E.MERGENT, INC. MERGER PROPOSAL - YOUR VOTE IS VERY IMPORTANT Dear Stockholders: The board of directors of E.mergent, Inc. has approved a merger in which E.mergent will be purchased by ClearOne Communications, Inc. As a result of the proposed merger, you will become a shareholder of ClearOne. The E.mergent board believes that the complementary product lines and businesses of ClearOne and E.mergent create an overall strategic fit. It also believes that the merger will create synergies and efficiencies that will accelerate product development and technological innovation. I cordially invite you to attend our special meeting of shareholders to vote on a proposal to approve the merger and the merger agreement. We cannot complete the merger unless the holders of a majority of the outstanding shares of E.mergent common stock approve it. The date, time, and place of the special meeting are May 31, 2002, 10:00 a.m., local time, E.mergent, Inc., 6110 Golden Hills Drive, Golden Valley, MN 55416. Your board of directors has carefully considered the terms and conditions of the merger and has determined that the merger is advisable, in the best interests of our stockholders and on terms that are fair to our stockholders. Accordingly, except for one director who abstained due to a conflict of interest, your board of directors has unanimously approved the merger agreement and the merger and recommends that you vote for adoption and approval of the merger agreement and approval of the merger. If the merger is completed, ClearOne will issue, or reserve for issuance upon the exercise of assumed E.mergent stock options, a total of 873,000 shares of ClearOne common stock and pay a total of $7,300,000 in cash in exchange for all of E.mergent's outstanding common stock shares and stock options. Assuming that E.mergent does not issue any additional shares prior to the merger, for each share of E.mergent common stock you hold, you will receive in the merger between approximately $1.17 to $1.23 in cash and up to approximately 0.145 of a share of ClearOne common stock. The exact amount of cash and stock that you will receive for each E.mergent share depends on the number of E.mergent shares outstanding immediately prior to the completion of the merger, the exercise of E.mergent stock options prior to the merger and other factors. The common stock of ClearOne (which was formerly known as Gentner Communications Corporation) is traded on the Nasdaq National Market System under the symbol "CLRO." On May 3, 2002, the closing price of ClearOne common stock was $17.20 per share. Following this letter you will find a formal notice of the special meeting and a proxy statement/prospectus providing you with detailed information concerning the merger agreement, the merger, E.mergent and ClearOne. In particular, you should carefully consider the discussion in the section entitled "Risk Factors" beginning on page 21 of this document, including those risk factors that are incorporated by reference into this document. It is also accompanied by the most recent annual report on Form 10-KSB for E.mergent, the most recent annual report on Form 10-K for ClearOne, certain other reports previously filed by ClearOne with the Securities and Exchange Commission and certain other relevant documents. You can also obtain information about ClearOne and E.mergent from documents filed with the Securities and Exchange Commission. Please read this entire document carefully. We enthusiastically support the merger and urge you to vote "FOR" the merger and the merger agreement. Thank you, and I look forward to seeing you at the special meeting. Sincerely, /s/ James W. Hansen James W. Hansen Chief Executive Officer and President - -------------------------------------------------------------------------------- NEITHER THE SECURITIES AND EXCHANGE COMMISSION NOR ANY STATE SECURITIES COMMISSION HAS APPROVED OR DISAPPROVED OF THE MERGER OR THE SHARES OF CLEARONE'S COMMON STOCK TO BE ISSUED IN THE MERGER, OR DETERMINED IF THIS DOCUMENT IS ACCURATE OR ADEQUATE. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE. - -------------------------------------------------------------------------------- This document is dated May 7, 2002 and was first mailed to E.mergent stockholders on or about May 9, 2002.

QUESTIONS AND ANSWERS ABOUT THE MERGER The following are some questions that you, as a stockholder of E.mergent, may have and answers to those questions. After this questions and answers section is a summary of the other information included in the proxy statement/prospectus. These questions and answers and the following summary section may not address all of the information that may be important to you as a stockholder of E.mergent. E.mergent and ClearOne urge you to read carefully the remainder of this proxy statement/prospectus because the information in these sections is not complete and additional important information is contained in the remainder of this proxy statement/prospectus, the annexes to this proxy statement/prospectus and the documents referred to or incorporated by reference in this proxy statement/prospectus. Q: Why am I receiving this document and proxy card? A: You are receiving this document and proxy card because you own shares of E.mergent common stock. E.mergent and ClearOne are proposing to combine the two companies through a merger of E.mergent into a subsidiary of ClearOne. This document describes a proposal that the E.mergent stockholders adopt the merger agreement between the parties and approve the merger at a special shareholders meeting. This document also gives you information about E.mergent and ClearOne and other background information so that you can make an informed investment decision, as ClearOne is offering its shares of common stock as part of the merger consideration that you will receive in the merger in exchange for your E.mergent common stock. Q: When and where is the special shareholders meeting? A: The E.mergent special shareholders meeting to consider and vote upon the merger will be held at E.mergent's offices at 6110 Golden Hills Drive, Golden Valley, MN 55416 on May 31, 2002 at 10:00 a.m., local time. Q: How do I vote on the merger? (see page 30) A: You are entitled to receive this notice and vote at the meeting if you were a shareholder of E.mergent on April 5, 2002, the record date for the meeting. To vote, first, please review the information contained or incorporated by reference in this document, including the annexes. It contains important information about E.mergent and ClearOne. It also contains important information about what the boards of directors of E.mergent and ClearOne considered in evaluating the merger. Next, complete and sign the enclosed proxy card, indicating how you wish to vote. Then, mail the proxy card in the enclosed return envelope as soon as possible so that your shares can be voted at the special meeting of E.mergent stockholders at which the merger agreement and the merger will be presented and voted upon. Alternatively, you may vote your proxy via phone or the Internet. You may vote your proxy by phone twenty-four (24) hours a day, 7 days a week, until 11:00 a.m., Central Time, one business day prior to the meeting by dialing 800-240-6326 and following the instructions. You may vote your proxy via the Internet twenty-four (24) hours a day, 7 days a week, until 11:00 a.m., Central Time, one business day prior to the meeting by going to http://www.eproxy.com/emrt and following the instructions. You may also attend the special meeting in person and vote at the special meeting instead of submitting a proxy. Q: If my shares are held in "street name" by a broker, will my broker vote my shares for me? A: No. Your broker will not be able to vote your shares without instructions from you. If you hold your shares in street name, you should receive with this proxy statement/prospectus a form for instructing you how to vote your shares through your broker. If you do not provide your broker with voting instructions, your shares may be considered present at the special meeting for purposes of determining a quorum, but will not be considered to have been voted in favor of adoption and approval of the merger agreement or approval of the merger and, therefore, such action will have the effect of a vote against the merger agreement and the merger. If you have instructed a broker to vote your shares and wish to change your vote, you must follow directions received from your broker to change those instructions. Please note, however, that if the holder of record of your shares is your broker, bank or other nominee and you wish to vote at the special meeting, you must bring a letter from the broker, bank or other nominee confirming that you are the beneficial owner of the shares. 1

Q: What if I do not indicate how to vote my proxy or indicate I abstain from the vote? (see page 29) A: If you properly sign and return your proxy but do not indicate how you want to vote, your proxy will be counted as a vote in favor of the merger agreement and the merger. If, however, you return your proxy and indicate that you are abstaining from voting, your proxy will have the same effect as a vote against the merger agreement and merger. Q: What if I don't return my proxy vote? (see page 29) A: If you fail to return your proxy, it will have the same effect as a vote against the merger agreement and the merger. Q: Can I change my vote after I have delivered my proxy or voted by phone or Internet? (see page 30) A: Yes. You can change your vote at any time before your proxy is voted at the special meeting of E.mergent stockholders at which the merger agreement and merger will be presented and voted upon. You can do this in one of four ways: o sending a written notice to the Secretary of E.mergent, if you are an E.mergent stockholder, before the meeting stating that you would like to revoke your proxy; o signing a later-dated proxy card and returning it by mail in time to be received before the meeting; o vote again by phone or Internet prior to 11:00 a.m., Central Time, on May 30, 2002 ; or o you can attend the special meeting and vote in person. Your attendance at the special meeting alone will not revoke your proxy. You must also vote at the special meeting in order to revoke your previously submitted proxy. Q: Should I send in my stock certificates now? A: No. If the merger is completed, we will send to you written instructions for exchanging your E.mergent stock certificates (or VideoLabs, Inc. stock certificates issued before E.mergent's name change) for ClearOne stock certificates.

SUMMARY The Companies ClearOne Communications, Inc. (see pages 64 and 72) 1825 Research Way Salt Lake City, Utah 84119 Telephone (801) 975-7200 ClearOne (formerly known as Gentner Communications Corporation) primarily develops, manufactures, markets and distributes products and services for the conferencing equipment, conferencing services, and broadcast markets. Until 1991, ClearOne's primary business was the sale of studio and transmitter-related equipment to broadcast facilities. Since then, ClearOne has applied its core digital audio technology to the development of products for audio and video conferencing, sound reinforcement, and assistive listening applications. In addition, ClearOne offers conferencing services, including conference calling, Webconferencing, audio and video streaming, and customer training and education. E.mergent, Inc. (see pages 63 and 72) 6110 Golden Hills Drive Golden Valley, MN 55416 Telephone (763) 542-0061 E.mergent sells its products and services through a global network of resellers and Original Equipment Manufacturers ("OEM"). E.mergent classifies its business into two segments: Products Division ("VideoLabs"), which designs, manufactures and markets a complete line of peripherals that support core technologies in the videoconferencing, audio visual, identification, education and medical markets and its Services Division ("ACS"), which is a full-service communications integration provider, specializing in the design, installation and support of meeting room technologies. E.mergent is headquartered in Golden Valley, Minnesota with locations in Plymouth, Minnesota; Maple Grove, Minnesota; Chicago, Illinois; and Des Moines, Iowa. ClearOne's and E.mergent's Reasons for the Merger (see pages 34 and 40) ClearOne and E.mergent are proposing to merge because they believe, for a variety of reasons, that each company will benefit from the combination of the two companies and the merger will result in a combined company that is better positioned to succeed in the audio and video conferencing markets than they would be separately. A complete discussion of the companies' respective reasons for proposing the merger is contained under the captions "E.mergent's Reasons for the Merger" beginning on page 33 and "Consideration of the Merger by ClearOne's Board of Directors and Reasons for the Merger" beginning on page 39. Recommendations of the E.mergent Board of Directors (see page 30) After careful consideration, E.mergent's board of directors determined that the merger is advisable, in the best interests of E.mergent stockholders and on terms that are fair to the stockholders of E.mergent. Accordingly, except for one director who abstained, E.mergent's board of directors unanimously approved the merger agreement and the merger and recommends that you vote "FOR" adoption and approval of the merger agreement and approval of the merger. The director who abstained chose to do so because he was previously employed by E.mergent's financial advisor, who rendered an opinion on the fairness of the merger as described below. Opinion of E.mergent's Financial Advisor (see page 35) In deciding to approve the merger, the E.mergent board of directors considered an opinion from its financial advisor, Goldsmith, Agio, Helms. On January 18, 2002, Goldsmith, Agio, Helms delivered its oral opinion, subsequently confirmed in writing, to the board of directors of E.mergent that, as of the date of such opinion, the consideration to be received by E.mergent stockholders as set forth in the merger agreement was fair, from a financial point of view, to the holders of E.mergent common stock. 3

The full text of the Goldsmith, Agio, Helms' written opinion is attached to this document as Annex C. We encourage you to read the opinion carefully. The opinion of Goldsmith, Agio, Helms does not constitute a recommendation as to how any holder of E.mergent common stock should vote with respect to the merger agreement and the merger. Shareholder Approval (see page 29) The affirmative vote of the holders of a majority of the outstanding shares of E.mergent common stock is required to approve the merger agreement and merger. Each share of E.mergent common stock will be entitled to one vote per share. As a result, you will be entitled to cast one vote per share of E.mergent common stock that you owned as of April 5, 2002, the record date for the E.mergent special meeting. As of May 3, 2002, there were 5,931,280 shares of E.mergent common stock outstanding. Holders of approximately 40% of the outstanding shares of E.mergent common stock have already agreed to vote in favor of approving the merger agreement and the merger. ClearOne stockholders are not required to vote on the merger agreement or the merger. Structure and Effects of the Merger (see page 47) At the effective time of the merger, E.mergent will be merged into a wholly owned subsidiary of ClearOne, with the subsidiary continuing as the surviving entity. As part of the process, the stockholders of E.mergent will become stockholders of ClearOne, and their rights as stockholders will be governed by the ClearOne articles of incorporation and bylaws, as currently in effect, and the laws of the State of Utah. Following the merger, ClearOne intends to maintain E.mergent's operations as a wholly-owned subsidiary of ClearOne for some period of time. The membership of ClearOne's board of directors will remain unchanged as a result of the merger. ClearOne and E.mergent anticipate that following the merger Robin Sheeley, E.mergent's current Chief Technical Officer will become the Chief Technology Officer of ClearOne, while James Hansen will resign as E.mergent's Chairman, Chief Executive Officer, President and Treasurer and Jill Larson will resign as E.mergent's Vice President-Administration and Corporate Secretary. If the merger is completed, ClearOne will issue, or reserve for issuance upon the exercise of assumed E.mergent stock options, a total of 873,000 shares of ClearOne common stock and pay a total of $7,300,000 in cash in exchange for all of E.mergent's outstanding common stock shares and stock options. As a result, each outstanding share of E.mergent common stock will be converted into the right to receive cash and a fraction of a share of ClearOne common stock. For each of your shares of E.mergent common stock you will receive a payment of cash between approximately $1.17 and $1.23 and up to approximately 0.145 of a share of ClearOne common stock. The exact amount to be paid per E.mergent share depends on a number of factors, including the average closing price of ClearOne common stock and the number of E.mergent stock options outstanding, both of which are determined immediately prior to the merger. As a result, we cannot tell you at this time the exact amount of cash and stock that you will receive for your E.mergent common stock. The chart below, however, gives examples of the approximate amount of cash and stock that you would receive based on a range of closing prices for ClearOne common stock (including the actual closing sales price of $17.20 on May 3, 2002) and assumptions about options outstanding at the time of merger. 4

Please note that the above table contains examples based on such assumptions. The actual amounts you will receive in the merger may differ from such examples. For a discussion of the actual calculation of the amounts to be exchanged in the merger, please see the discussion entitled "Conversion of E.mergent Common Stock" beginning on page 47. Additionally, ClearOne will not issue fractional shares. If the total number of shares of ClearOne common stock that you are entitled to receive includes a fraction of a share, you will instead receive cash, without interest, rather than that fractional share. Changes in the trading price of ClearOne common stock prior to the merger will not change the total amount of cash or total number of shares being paid by ClearOne in the merger. Of course, changes in the trading price of ClearOne common stock will affect the actual value of the ClearOne common stock that you will receive in the merger. However, either ClearOne or E.mergent may terminate the merger agreement if the weighted average closing price of ClearOne common stock as quoted on the Nasdaq National Market for the fifteen (15) trading days ending one day prior to the date of the scheduled completion of the merger is greater than $23 or less than $14. Options to purchase shares of E.mergent common stock outstanding immediately prior to completion of the merger will be converted into options to purchase shares of ClearOne common stock after the merger. The number of ClearOne shares issuable upon the exercise of these options, and their applicable exercise prices, will be adjusted based on the value of the ClearOne common stock and cash each share of E.mergent stock received in the merger. The formula for determining the exchange ratio for assuming the E.mergent stock options is described beginning on page 47 in this proxy statement/prospectus. Each share of E.mergent common stock held by E.mergent, ClearOne, or any direct or indirect wholly-owned subsidiary of ClearOne immediately prior to the effective time of the merger will be canceled and extinguished. Fifty thousand three hundred and seventeen (50,317) shares of E.mergent common stock currently held by E.mergent as treasury shares will be issued to E.mergent employees as part of an anticipated bonus prior to completion of the merger and will be 5

treated as issued and outstanding shares at the effective time of the merger. The 50,317 shares will be allocated equally among all employees, for a bonus of approximately 689 shares each. Conflicts of Interest of Directors and Officers (see page 39) Some of E.mergent's directors and executive officers have interests in the merger that are different from, or in addition to, those of E.mergent stockholders generally. These include interests of James Hansen, E.mergent's Chief Executive Officer and Chairman, Robin Sheeley, the Chief Technical Officer and a director, and Jill Larson, the Vice President-Administration and Corporate Secretary. In the event that the employment of these executive officers is terminated immediately after the merger (as is currently anticipated for Mr. Hansen and Ms. Larson but not for Mr. Sheeley), it is estimated that the severance payments payable under their employment agreements, plus the value of the related benefits, would be approximately $189,000 to Mr. Hansen, $120,000 to Ms. Larson, and $160,000 to Mr. Sheeley. Also, Mr. Hansen has an option to buy 10,000 E.mergent common shares at $3.37 per share and Ms. Larson has an option to buy 3,333 E.mergent common shares at $1.47, which options will become vested immediately prior to the closing of the merger. Ms. Larson and Messrs. Hanson and Sheeley will also each receive approximately 689 shares of E.mergent common stock when the treasury shares of E.mergent common stock are issued to employees as a bonus prior to completion of the merger. E.mergent's board of directors was aware of these interests and considered them, among other matters, when it approved the merger agreement and the merger. All disinterested directors voted in favor of the merger. The Merger Agreement (see page 47) We have attached the merger agreement as Annex A to this proxy statement/prospectus. We urge you to read the merger agreement carefully. In addition to the features summarized below, in the merger agreement each company has made certain representations, warranties and agreements regarding the merger. Conditions to Completion of the Merger. ClearOne's and E.mergent's obligations to complete the merger are subject to the satisfaction of conditions specified in the merger agreement, including the following: o adoption and approval of the merger agreement and approval of the merger by the requisite holders of the outstanding E.mergent common stock; o the absence of any law, injunction or order preventing the completion of the merger; o with regard to ClearOne's registration statement on Form S-4 of which this document forms a part, no stop order suspending its effectiveness may be in effect and no proceedings for suspension of its effectiveness may be pending before or threatened in writing by the Securities and Exchange Commission; and o the continuing accuracy of the representations and warranties of ClearOne and E.mergent contained in the merger agreement, subject to certain exceptions. Except for the conditions that are required to be met by law, such as the first three items above, the conditions to completion of the merger may be waived by the company entitled to assert the condition. However, in the event that either E.mergent or ClearOne elect to waive a condition to closing that it's board of directors considers material, they intend to resolicit shareholder approval of the merger following appropriate disclosure of such waiver. Termination of the Merger; Fees Payable. ClearOne and E.mergent may mutually agree to terminate the merger agreement without completing the merger. In addition, either ClearOne or E.mergent may terminate the merger agreement under certain circumstances, including any of the following: o if ClearOne and E.mergent do not complete the merger by May 31, 2002; o if the E.mergent stockholders do not adopt and approve the merger agreement and approve the merger, provided such failure is not the result of a breach by E.mergent; or 6

o in the event that the weighted average closing price of ClearOne common stock as quoted on the Nasdaq National Market for the fifteen (15) trading days ending one day prior to the date of the scheduled completion of the merger is greater than $23 or less than $14. E.mergent may also terminate the merger agreement if it elects to enter into certain types of extraordinary transactions with a third party, such as a merger, business combination or sale of a material amount of assets or capital stock; it pays ClearOne the termination fees described below; and, otherwise complies with all of the restrictions in the merger agreement applicable to E.mergent's involvement with such an alternative proposal. ClearOne may also terminate the merger agreement if E.mergent stockholders holding 15% or more of the issued and outstanding shares of E.mergent elect to pursue dissenters' rights, whether such holders have perfected such rights or not. Additionally, ClearOne may terminate the merger under the following circumstances, in which case E.mergent must pay ClearOne the termination fees described below: o E.mergent's board of directors undertakes certain action, or fails to take certain action, unfavorable to the proposed merger, when addressing certain types of extraordinary transactions with a third party, such as a merger, exchange offer, business combination or sale of a material amount of assets or capital stock; or o E.mergent's board of directors withdraws, amends or modifies in a manner adverse to ClearOne the unanimous recommendation of its non-interested directors in favor of the adoption and approval of the merger agreement or the approval of the merger. If the merger is terminated under the circumstances described above as requiring the payment of termination fees E.mergent must pay ClearOne a fee of $1,000,000 in cash and reimburse ClearOne for up to $500,000 in actual legal, accounting and advisory fees and costs incurred by ClearOne. Alternatively, if ClearOne terminates the merger agreement for a material breach of any agreement on the part of E.mergent, or if any of E.mergent's representations or warranties are or become untrue in certain ways, then E.mergent must pay up to $500,000 of ClearOne's actual legal, advisory and accounting fees incurred in connection with the merger. Conversely, if E.mergent terminates the merger agreement for a material breach of any agreement on the part of ClearOne, or if any of ClearOne's representations or warranties are or become untrue in certain ways, then ClearOne must pay up to $500,000 of E.mergent's actual legal, advisory and accounting fees incurred in connection with the merger. E.mergent Prohibited from Soliciting Other Offers (see page 53) E.mergent has agreed that, while the merger is pending, it will not initiate or, subject to some exceptions, engage in discussions with third parties regarding some types of extraordinary transactions, such as a merger, business combination or sale of a material amount of assets or capital stock. Share Ownership of Management As of the close of business on the record date for the special meeting of E.mergent stockholders at which the merger agreement and the merger will be presented and voted upon, directors and executive officers of E.mergent (and their respective affiliates) collectively owned approximately 41% of the outstanding shares of E.mergent common stock. This does not include 342,000 shares of E.mergent common stock issuable upon the exercise of presently exercisable options which these directors and officers beneficially own. If all of these stock options had been exercised prior to the record date for the special meeting, the directors and executive officers of E.mergent (and their respective affiliates) would collectively own approximately 44% of the outstanding shares of E.mergent common stock entitled to vote at the special meeting. Material United States Federal Income Tax Consequences of the Merger (see page 42) Fredrikson & Byron, P.A., counsel to E.mergent, and Jones, Waldo, Holbrook & McDonough, P.C., counsel to ClearOne, have provided tax opinions regarding the material U. S. federal income tax consequences of the merger. In summary, the opinions provide that, assuming that the ClearOne common stock that 7

E.mergent shareholders receive in the merger has a value above approximately $10.25 per share, so that the value of the stock is greater than the value of the cash that they receive in the merger, the merger will qualify as a "reorganization" under section 368(a) of the Internal Revenue Code. In that case, E.mergent's stockholders will only recognize gain, if any, for federal income tax purposes, to the extent they receive cash in the merger. In addition, E.mergent stockholders will recognize gain or loss, as the case may be, to the extent they receive cash in lieu of the receipt of a fractional share of ClearOne's common stock. However, if the merger is completed at a time when the ClearOne common stock is below approximately $10.25 per share, so that the stock has a value less than the cash that the E.mergent stockholders receive in the merger, the merger may not so qualify as a "reorganization." In such event, E.mergent stockholders will recognize gain, if any, for federal income tax purposes, based on both the cash and the value of the ClearOne stock received in the merger. Under the merger agreement, ClearOne and E.mergent may choose to complete the merger even though the value of the ClearOne common stock declines below $10.25 and the merger does not qualify as a reorganization under Section 368(a) of the Internal Revenue Code. However, in the event that prior to closing, ClearOne and E.mergent determine, due a decline in the value of ClearOne common stock, the gain based on both the cash and ClearOne stock would be taxable because the merger did not qualify as a "reorganization," and neither E.mergent nor ClearOne terminates the merger due to such a decline as allowed under the merger agreement, ClearOne and E.mergent intend to advise E.mergent's shareholders of such circumstances and resolicit their approval of the merger. Tax matters are complicated, and the tax consequences of the merger to you will depend on the facts of your own situation. We urge you to contact your own tax advisor to understand fully how the merger will affect you, including how any state, local, or foreign tax laws may apply to you. Appraisal Rights (see page 44) You are entitled to appraisal rights in connection with the merger under Section 262 of the Delaware General Corporate Law. If appraisal rights are available, the merger is completed, and you (1) file written notice with E.mergent of an intention to exercise appraisal rights prior to the time the vote is taken at the special meeting, (2) do not vote in favor of the merger agreement or merger and (3) follow the other procedures set forth in Section 262, you generally will be entitled to be paid the fair value of the shares of E.mergent common stock in cash for which appraisal rights have been perfected. You should carefully read the disclosure beginning on page 44 and included in Annex D. The exercise of appraisal rights is a complicated legal act and you should not rely solely on the disclosure in this document to inform you how to perfect your rights. Your failure to comply with the procedures described in Annex D will result in the loss of your appraisal rights. Restrictions on the Ability to Sell ClearOne Common Stock Received in the Merger (see page 62) Generally, the shares of ClearOne common stock that you receive in connection with the merger will be freely transferable unless you are deemed to be an affiliate of E.mergent or ClearOne prior to the completion of the merger under the Securities Act of 1933. Shares of ClearOne common stock received by E.mergent's or ClearOne's affiliates in the merger may only be sold in compliance with Rule 145 under the Securities Act of 1933. The ClearOne common stock is listed on the Nasdaq National Market under the symbol "CLRO." 8

Risks of the Merger (see page 21) By voting to approve the merger, you will be choosing to invest in ClearOne common stock. An investment in ClearOne common stock involves a high degree of risk. In deciding whether to vote for the merger, you should carefully consider the risks that are discussed in detail in this proxy statement/prospectus under the caption "Risk Factors." No Governmental Approvals or Regulatory Requirements We are not aware of any material federal or state regulatory requirements or approvals required for completion of the merger, other than filing a certificate of merger in Delaware at or before the effective time of the merger. Completion of the Merger We will complete the merger when all of the conditions to completion of the merger contained in the merger agreement have been satisfied or waived. We currently expect that to occur promptly after the meeting of the E.mergent stockholders to vote on the merger. However, because the merger is subject to such conditions, some of which are beyond our control, we cannot predict the exact timing. 9

Selected Historical Financial Data E.mergent The following selected historical financial data for the most recent five fiscal years ended December 31, 2001 are derived from the audited financial statements of E.mergent.

ClearOne The following selected historical financial data for the most recent five fiscal years ended June 30, 2001 are derived from the audited consolidated financial statements of ClearOne. The financial data for the six-month periods ended December 31, 2001 and 2000 are derived from unaudited financial statements. The unaudited financial statements include all adjustments, consisting of normal recurring adjustments, which ClearOne considers necessary for a fair presentation of the financial position and the results of operations for these periods.

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION The following unaudited pro forma condensed combined financial information gives effect to the acquisitions of Ivron Systems, Ltd. and E.mergent by ClearOne. Effective October 3, 2001, ClearOne, through a wholly owned subsidiary, acquired the shares of Ivron Systems for a combination of cash and stock. The share purchase agreement dated October 3, 2001 was amended April 8, 2002. On January 21, 2002, ClearOne entered into a definitive agreement to acquire the stock of E.mergent for a combination of cash and stock. Both of these acquisitions either have been or will be accounted for under the purchase method of accounting. The unaudited pro forma condensed combined statements of operations for the year ended June 30, 2001 and the six months ended December 31, 2001 have been prepared as if each transaction occurred on July 1, 2000, whereas the pro forma condensed combined balance sheet as of December 31, 2001 has been prepared as if each transaction occurred on December 31, 2001. Please see the notes to these pro forma combined condensed statements regarding certain assumptions utilized in the preparation of the statements. ClearOne's fiscal year ends on June 30 while the fiscal years of Ivron Systems and E.mergent historically ended on December 31. Accordingly, ClearOne has combined its historical results from continuing operations for the year ended June 30, 2001 with the unaudited financial results of Ivron Systems and E.mergent for the fiscal year ended June 30, 2001, comprising the last six months of operations of Ivron Systems and E.mergent for the year ended December 31, 2000 and the first six months of operations of Ivron Systems and E.mergent for the year ended December 31, 2001. The unaudited pro forma condensed combined statement of operations presented for the six months ended December 31, 2001 includes the historical unaudited financial results from continuing operations of ClearOne and E.mergent for the six months ended December 31, 2001. The historical unaudited financial results from continuing operations of Ivron Systems are included from July 1, 2001 to October 2, 2001, with the results from October 3, 2001 to December 31, 2001 already consolidated in ClearOne's operating results. Unaudited pro forma condensed combined financial information is presented for illustrative purposes only and is not necessarily indicative of the financial position or results of operations that would have actually been reported had the transactions occurred on the proforma dates indicated above, nor is it necessarily indicative of future financial position or results of operations. These unaudited pro forma condensed combined financial statements are based on the respective historical financial statements of ClearOne, Ivron Systems and E.mergent and do not incorporate, nor do they assume, any benefits from cost savings or synergies of operations of the combined company. The unaudited pro forma condensed combined financial information should be read together with ClearOne's historical financial statements and those of Ivron Systems and E.mergent, including the related notes and "Management's Discussion and Analysis of Financial Condition and Results of Operations," all of which are incorporated by reference. Pro forma results of operations include adjustments, which are based upon management's preliminary estimates, to reflect the allocation of the purchase consideration to the acquired assets and liabilities of E.mergent. The final allocation of the purchase consideration will be determined after completion of the merger and will be based on appraisals and a comprehensive final evaluation of the fair value of E.mergent's tangible assets, liabilities and identifiable intangible assets after completion of the merger. Accordingly, while ClearOne does not anticipate that the final valuation and related intangible asset allocation will differ significantly from the preliminary valuation, the final determination of tangible and intangible assets may result in depreciation and amortization expense that is higher than the preliminary estimates of these amounts. 12

Notes to Unaudited Pro Forma Condensed Combined Financial Information NOTE 1. On October 3, 2001, ClearOne executed a share purchase agreement, which was amended on April 8, 2002, with the shareholders of Ivron Systems. ClearOne paid cash of $6,000,000 for all issued and outstanding shares of Ivron Systems, cash of $650,000 for all outstanding options to purchase common shares of Ivron Systems, and incurred acquisition costs of $274,000 in the transaction. Additional consideration may be issued to Ivron Systems' shareholders if certain contingencies related to future earnings targets as defined in the share purchase agreement are met. The following is a summary of the purchase price allocation using the October 3, 2001 balance sheet of Ivron Systems (in 000's): Cash $ 460 Accounts receivable 132 Inventory 608 Fixed assets 21 Goodwill and other intangible assets 6,144 Accounts payable (175) Accrued expenses (266) ------------- Total $6,924 ============= On January 21, 2002, ClearOne entered into a definitive agreement to acquire E.mergent. Under the terms of the agreement, ClearOne will acquire all of the issued and outstanding stock of E.mergent; thereby acquiring title to all assets and assuming all liabilities of E.mergent. As consideration in the transaction, ClearOne will pay cash of $7,300,000 and issue 873,000 shares of its common stock, less the aggregate number of shares of common stock allocated to E.mergent's outstanding stock options assumed by ClearOne in the merger because, in accordance with the agreement and plan of merger, the 873,000 shares of ClearOne common stock are allocated first to E.mergent stock options being assumed by ClearOne. Outstanding E.mergent stock options will be converted to options to purchase ClearOne's common stock at the ratio specified in the agreement and plan of merger. The value of such stock consideration is based on ClearOne's average closing price two days prior to and two days subsequent to January 21, 2002 (the announcement date for the acquisition and merger) of $16.55. Additionally, ClearOne expects to incur acquisition costs of $890,000 in the transaction (including approximately $312,000 for anticipated severance payments to terminating E.mergent executives). E.mergent expects to incur transaction related costs of approximately $850,000. Such costs will be paid immediately prior to the merger. The following is a summary of the preliminary purchase price allocation using the December 31, 2001 balance sheet of E.mergent (in 000's): Cash $ (43) Accounts receivable 3,300 Inventory 3,736 Fixed assets 473 Other assets 678 Shareholder receivable 122 Goodwill and other intangible assets 16,775 Accounts payable (862) Accrued expenses and customer deposits (619) Unearned maintenance contracts (1,064) Capital leases and long-term debt (641) ------------- Total $ 21,855 ============= The purchase price was determined as follows: Cash to be paid to E.mergent shareholders $ 7,300 Value of ClearOne common stock issued to E.mergent shareholders (751,181 shares 12,432 x $16.55) Fair value of ClearOne options issued to E.mergent option holders, determined using the Black-Scholes model 1,233 Acquisition costs to be paid by ClearOne 890 ------------- Total purchase price $ 21,855 ============= NOTE 2. The unaudited pro forma condensed combined balance sheet includes the adjustments necessary to give effect to the Ivron Systems and E.mergent acquisitions as if they had occurred on December 31, 2001 as noted above. The unaudited pro forma condensed combined statements of operations include the adjustments necessary to give effect to the Ivron Systems and E.mergent acquisitions as if they had occurred on July 1, 2000. Adjustments included in the pro forma condensed combined financial statements are summarized as follows: 16

(A) On April 8, 2002, ClearOne completed its negotiations of an amendment to the Ivron Systems share purchase agreement whereby the future contingent consideration to be received by the Ivron shareholders was reduced. Such amendment resulted from the determination that certain of the intended benefits of the Ivron acquisition have not been achieved and are likely not to be achieved. Based on these negotiations and the resulting amendment to the Ivron share purchase agreement, the purchase price allocation has been adjusted to reflect the overall decrease in the purchase price of Ivron. The revised purchase price allocation was based on an analysis performed by an independent financial consulting firm, LECG, LLC. The revised final calculation has the effect of decreasing the fair value of the intangible assets previously recorded. Therefore, the deferred consideration originally recorded was also reduced. The initial deferred consideration reflected the difference between the fair value of the assets acquired and the cash consideration paid, pursuant to the provisions of FASB Statement No. 141 (FAS No. 141), Business Combinations. Deferred consideration still may be paid out if certain contingencies related to future earnings targets, as defined in the amended share purchase agreement between ClearOne and the Ivron Systems shareholders, are met. However, any such additional consideration will be allocated to goodwill. (B) Elimination of E.mergent and Ivron historical goodwill and other intangibles (and the related amortization) that were or will be revalued as part of the purchase price allocation. (C) Values were assigned to intangibles related to the Ivron Systems acquisition as follows: developed technology - $5,780,000; goodwill - $364,000. These allocations are based upon a final report from LECG, LLC, an independent financial consulting firm. The developed technology was determined to have useful lives as follows, with the resulting impact on amortization expense: Amortization for the Six months ended Fiscal Year ended Value of Technology Useful Life December 31, 2001 June 30, 2001 ------------------------------------------------------------------------------ $ 135,000 3 $ 11,250 $ 45,000 1,002,000 5 50,100 200,400 4,643,000 15 77,383 309,533 --------------------- ------------------------------------------ $ 5,780,000 $138,733(i) $ 554,933 ===================== ========================================== (i) Reflects the amortization expense from July 1, 2001 to October 2, 2001, the period prior to the acquisition of Ivron Systems by ClearOne. (D) The tax impact of amortization, as calculated using ClearOne's blended statutory rate of 37.2%. (E) Cash consideration to be paid to former E.mergent shareholders of $7,300,000 plus ClearOne and E.mergent transaction costs of $1,740,000. (F) Amount represents goodwill of $16,775,000 including capitalized acquisition costs of approximately $890,000 (including approximately $312,000 for anticipated severance payments to terminating E.mergent executives). For purposes of these pro forma financial statements and based upon a preliminary valuation by LECG, LLC, ClearOne's independent financial consulting firm, the excess of the purchase price over the fair value of the tangible assets acquired has been allocated to goodwill. Based on LECG, LLC'S preliminary analysis, ClearOne does not believe that any material value should be allocated to acquired intangible assets other than goodwill. Accordingly, pursuant to FAS No. 142, Goodwill and Other Intangible Assets, no related amortization has been reflected in the accompanying pro forma statements of operations. (G) Represents the elimination of an investment that was deemed to have no future value to ClearOne. (H) Represents the fair value, as determined in accordance with FASB Interpretation No. 44, Accounting for Certain Transactions Involving Stock Compensation--An Interpretation of APB Opinion 25, of the vested options to purchase ClearOne common stock that were issued in exchange for vested options to purchase E.mergent common stock in conjunction with the agreement and plan of merger. The weighted average fair value of the ClearOne options is approximately $10.12, using the Black-Scholes method, as determined using the following assumptions: volatility of 62%, weighted average expected life of the options of approximately 2 years, dividend yield of 0%, and risk-free interest rate of 4.38%. (I) Elimination of E.mergent's historical equity. (J) In accordance with the agreement and plan of merger, the treasury stock held by E.mergent, which consisted of 50,317 shares, will be distributed to E.mergent employees immediately prior to the consummation of the merger. (K) Reflects the value of the shares of ClearOne common stock issued to holders of E.mergent common stock as follows: (751,181 shares x $16.55 per share). The per share price is based on ClearOne's average closing price two days prior to and two days subsequent to January 21, 2002 (the announcement date for the acquisition and 17

merger) and assumes that no E.mergent stock options outstanding on the date of the merger agreement have been exercised. (L) Elimination of sales and related cost of sales between ClearOne and E.mergent. 18

HISTORICAL AND PRO FORMA COMPARATIVE PER SHARE DATA The following table compares historical and unaudited pro forma earnings (loss) per share and book value per share information for ClearOne and E.mergent. You should read the table together with the financial information for ClearOne and E.mergent incorporated by reference in this proxy statement/prospectus. You should not rely on the pro forma financial information as an indication of the results that ClearOne would have achieved if the merger had taken place earlier or of the results of ClearOne after the merger. The unaudited equivalent pro forma per share data are calculated based on the unaudited pro forma combined per share data (which gives effect to the Ivron acquisition and the E.mergent acquisition) multiplied by an exchange ratio of 0.20102 of a share of ClearOne common stock for each share of E.mergent common stock outstanding. This exchange ratio (i) reflects the average closing price of the ClearOne common stock two days prior to and two days subsequent to January 21, 2002 of $16.55, and (ii) assumes that no E.mergent stock options outstanding on the date of the merger agreement have been exercised. The actual exchange ratio will not be determined until shortly before the completion of the merger and will impact the pro forma per share amounts shown on this page.

COMPARATIVE PER SHARE MARKET PRICE DATA E.mergent common stock is traded on the Nasdaq SmallCap Market under the symbol "EMRT." ClearOne common stock is traded on the Nasdaq National Market under the symbol "CLRO." The following table shows the closing prices per share of E.mergent common stock and ClearOne common stock as reported on the Nasdaq SmallCap Market and the Nasdaq National Market, respectively, on (1) January 18, 2002, the business day preceding the public announcement that ClearOne and E.mergent had entered into the merger agreement and (2) May 3, 2002. The following table also includes the equivalent price per share of E.mergent common stock on those dates. This equivalent per share price reflects the combined value of the ClearOne common stock and cash that you would receive for each share of your E.mergent common stock if the merger had been completed on any of these dates. E.mergent ClearOne Equivalent Common Stock Common Stock Price Per Share ------------ ------------ --------------- January 18, 2002 $2.95 $17.16 $3.41 (1) May 3, 2002 $3.40 $17.20 $3.41 (2) (1) Represents the combined value of cash ($1.23) and stock ($2.18). (2) Represents the combined value of cash ($1.23) and stock ($2.18). Assumes that no E.mergent stock options were exercised after January 18, 2002. Because the market price of E.mergent common stock and ClearOne common stock may increase or decrease before the completion of the merger, you are urged to obtain current market quotations. 20

RISK FACTORS By voting in favor of the approval of the merger agreement and merger, E.mergent stockholders will be choosing to invest in ClearOne common stock. An investment in ClearOne common stock involves a high degree of risk. In addition to the other information contained in this proxy statement/prospectus, E.mergent stockholders should carefully consider the following risk factors in deciding whether to vote for the merger. Any of the following risks could seriously harm ClearOne's or E.mergent's business and financial results and cause the value of ClearOne's or E.mergent's securities to decline which, in turn, could cause you to lose all or part of your investment. Risks Relating to the Merger The ClearOne common stock to be received by E.mergent stockholders in the merger and E.mergent's common stock will fluctuate in value. Upon completion of the merger, each share of common stock of E.mergent will be exchanged for a specific amount of cash and a fraction of a share of ClearOne common stock. The cash portion and the share portion that you receive as merger consideration will depend on a number of factors including the weighted-average closing price of ClearOne stock during the ten (10) trading days ending one day prior to the completion of the merger and the number of E.mergent stock options exercised prior to the merger. (See page 47 of this document for a description of the merger consideration). The specific dollar value of ClearOne common stock that you will receive upon completion of the merger will depend on the market value of ClearOne common stock on the date of completion of the merger, and could vary significantly from its current value. The specific dollar value of the E.mergent common stock that you will exchange in the merger could also vary from its current value. The value of both companies' stock has been volatile and you should expect them to continue to fluctuate. These values may substantially decrease from the date you submit your proxy. We urge you to obtain recent market quotations for ClearOne common stock and E.mergent common stock. Neither ClearOne nor E.mergent can predict or give any assurance as to the respective market prices of its common stock at any time before or after completion of the merger. ClearOne may experience problems integrating the businesses of ClearOne and E.mergent. Difficulties in integrating the businesses, operations, product lines and personnel of ClearOne and E.mergent could cause ClearOne to not realize the expected benefits of the merger and incur unanticipated costs. If ClearOne fails to successfully integrate E.mergent's business into ClearOne's business, ClearOne will incur substantial costs, which will increase its expenses and potentially decrease profitability. ClearOne's ability to achieve the benefits of the merger will depend in part on the integration of technology, operations, products and personnel of ClearOne and E.mergent. The integration process will be a complex, time-consuming and expensive process. The challenges involved in this integration include the following: o retaining the combined company's customers and suppliers by maintaining client service standards, business focus and product quality during the period of integration; o retaining certain key employees that are important to the profitable growth of ClearOne's and E.mergent's combined business; o developing and implementing uniform standards, controls, procedures and policies; o implementing potential cost savings measures by eliminating redundant operations and expenses without causing customer service and employee morale to suffer; and o effectively integrating different administrative and information systems at multiple, geographically dispersed locations in an efficient and timely manner. If ClearOne is unsuccessful in integrating E.mergent's business into its own, the combined revenues could fall or grow at a slower rate than anticipated, ClearOne could incur substantial unexpected expenses, and ClearOne could fail to realize the anticipated benefits of the merger. In addition, any integration problems ClearOne experiences could divert ClearOne management's attention from other business opportunities, which could result in slower revenue growth than anticipated or in declines in revenue. 21

ClearOne may not realize the expected benefits of the merger due to difficulties with maximizing the anticipated advantages of combining the businesses. ClearOne's ability to achieve the benefits of the merger will also depend in part on its ability to take advantage of the combined company's product and customer base. There is no assurance that ClearOne will be able to efficiently and effectively utilize the company's combined customer base to take advantage of cross-selling opportunities that will result in the sale of more products than if the companies were separate. ClearOne will need to successfully integrate and adapt each company's product line to create new product offerings that are attractive to customers. The challenges faced by ClearOne and E.mergent in maximizing the anticipated advantages of combining the businesses include: o combining sales efforts and procedures so that customers can easily do business with the combined company, and sales agents can effectively access the customers of the other company; and o combining product offerings and product lines effectively and quickly, including technical integration by each company's respective engineering teams. Customer uncertainty or concerns about the merger could have an adverse effect on revenues and profitability in near-term quarters for either or both companies. ClearOne's and E.mergent's customers may, in response to the announcement or consummation of the merger, delay or defer purchasing decisions. This could occur because they may be reluctant to purchase either company's product if they are uncertain about the direction of the combined company's product offerings and its willingness to support and service existing products. Specifically, certain customers of E.mergent are competitive with ClearOne in certain product markets and such customers could be reluctant to continue its historical purchasing patterns with the involvement of ClearOne. Similarly, certain customers of ClearOne have been competitive with E.mergent and there could be concerns that the combined company would result in additional competition for them. Since announcement of the merger, ClearOne and E.mergent have received questions from current and prospective customers about the status of the merger and anticipated product integration plans, which have not yet been determined. If one large customer, or a significant group of small customers, were to delay their purchase decisions pending resolution of the merger or seek products from other vendors, the quarterly revenues of either ClearOne or E.mergent could be below expectations. The merger could impair existing company relationships with employees, thereby increasing employee related expenses. E.mergent's and ClearOne's employees may experience uncertainty about their future role with the combined company. ClearOne has yet to announce its strategies with regard to employee changes resulting from the merger. This may adversely affect the combined company's ability to retain or attract key management, marketing and technical personnel. Such employee uncertainty could also cause employee productivity to suffer. Officers and directors of E.mergent have potential conflicts of interest. E.mergent stockholders should be aware of potential conflicts of interest and the benefits available to E.mergent directors when considering E.mergent's board of directors' recommendation to approve the transaction. E.mergent officers and directors have stock options, indemnification rights and/or employment agreements that provide them with interests in the transaction that are different from, or in addition to, interests of E.mergent stockholders. These interests include the following: o the accelerated vesting of stock options upon completion of the merger; o the receipt of severance benefits under employment agreements upon termination of employment following the merger; and o the indemnification and insurance coverage with respect to acts taken and omissions to take action in their capacities as directors and officers of E.mergent. The E.mergent board of directors was aware of these interests when it approved the merger agreement and merger. For a more detailed description of these interests, see "Interests of E.mergent Officers and Directors in the Transaction" on page 39. 22

Due to the preliminary nature of the purchase price allocation, the impact of additional amortization of intangibles other than goodwill and subsequent impairment analyses of goodwill relating to the merger could adversely affect ClearOne's future operating results. In accordance with United States generally accepted accounting principles that apply to ClearOne, ClearOne will account for the merger using the purchase method of accounting. Under purchase accounting, ClearOne will record the following as the cost of acquiring the business of E.mergent: o the cash paid to E.mergent stockholders in the merger; o the market value of ClearOne common stock issued in connection with the merger; o the fair value, using the Black-Scholes model, of the options to acquire ClearOne common stock that are issued to holders of options to purchase E.mergent common stock in connection with the merger; and o the amount of direct transaction costs paid by ClearOne. ClearOne will allocate the cost of the items described above to the individual assets acquired and liabilities assumed, including intangible assets such as acquired technology based on their respective fair values. Any excess of the consideration paid over the fair values of tangible and identifiable intangible assets will be recorded as goodwill. Intangible assets other than goodwill, if any, will be amortized over their respective useful lives. In accordance with the provisions of FASB Statement No. 142, "Goodwill and Other Intangible Assets," ClearOne will not amortize any goodwill recorded. Instead, such goodwill will be evaluated for potential impairment on at least an annual basis. Any impairment will be recorded in the period in which it is determined to exist. The amount of purchase cost allocated to goodwill and other intangibles is estimated to be approximately $16.8 million, computed using the estimated purchase price of $21.9 million which is based on the average closing price ($16.55) of ClearOne's common stock two days prior to and two days subsequent to January 21, 2002. Although ClearOne does not anticipate that a material change will occur, the estimated goodwill reflected in the unaudited condensed combined balance sheet as of December 31, 2001 could change upon completion of the merger and the receipt of a final independent valuation of intangible assets based on the final purchase price, which will subsequently be requested by ClearOne. In the event the final purchase price valuation results in an allocation of a portion of the purchase price to other intangible assets, which are subject to amortization, pro forma amortization expense could be higher than the amount currently reflected in the pro forma statements of operations. ClearOne and E.mergent expect to incur significant costs associated with the merger. ClearOne estimates that it will incur direct transaction costs of approximately $890,000 associated with the merger (including approximately $312,000 for anticipated severance payments to terminating E.mergent executives), which will be included as a part of the total purchase price for accounting purposes. In addition, E.mergent estimates that it will incur direct transaction costs of approximately $850,000, including the fees and expenses payable to Goldsmith, Agio, Helms in connection with the merger (which fees will be in large part determined by the value of the ClearOne common stock and cash paid by ClearOne, calculated at the time of the merger). See "The Merger and Related Transaction - Opinion of E.mergent's Financial Advisor beginning on page 35 of this document. ClearOne believes the combined company may incur charges to operations, which currently cannot be reasonably estimated, in the quarter in which the merger is completed or the following quarters, to reflect costs associated with integrating the businesses and operations of ClearOne and E.mergent. There can be no assurance that the combined company will not incur additional material charges in subsequent quarters to reflect additional costs associated with the merger. The merger may be terminated by either ClearOne or E.mergent in the event the closing price of ClearOne common stock does not fall within a certain range. Under the terms of the merger agreement, if the weighted-average closing price of ClearOne common stock as quoted on the Nasdaq National Market for the fifteen (15) trading days ending one day prior to the date of the scheduled completion of the merger is greater than $23 or less than $14, either ClearOne or E.mergent may terminate the merger agreement. As a result, the merger may not be completed if either company concludes it is not in its best interest to complete the merger because of a substantial increase or decrease in the closing price of the ClearOne common stock. 23

Failure to complete the merger could have a negative impact on ClearOne's and E.mergent's stock price and future business. If the merger is not completed, ClearOne and E.mergent may be subject to the following material risks, among others: o ClearOne may be required to pay E.mergent up to $500,000 of E.mergent's expenses incurred in connection with the merger; o E.mergent may be required to pay ClearOne a termination fee of $1,000,000 plus an additional amount of up to $500,000 of ClearOne's expenses incurred in connection with the merger; o the price of ClearOne and E.mergent common stock may decline to the extent that the current market price of their respective common stock reflects a market assumption that the merger will be completed; o costs related to the merger, such as legal and accounting fees and some of the fees of E.mergent's financial advisor, must be paid even if the merger is not completed; and o the diversion of management attention from the day-to-day businesses of ClearOne and E.mergent and the unavoidable disruption to their employees and their relationships with customers and suppliers during the period before consummation of the merger may make it difficult for ClearOne or E.mergent to regain their respective financial market positions if the merger does not occur. Further, if the merger agreement is terminated and the E.mergent board of directors determines to seek another merger or business combination, E.mergent may not be able to find a partner willing to pay an equivalent or more attractive price than that which would be paid in the merger. The termination fee and restrictions on solicitation contained in the merger agreement may discourage other companies from trying to acquire E.mergent. Until completion of the merger, with some exceptions, E.mergent is prohibited from initiating or engaging in discussions with a third party regarding some types of extraordinary transactions, such as a merger, business, combination or sale of a material amount of assets or capital stock. In addition, E.mergent agreed to pay a termination fee to ClearOne in specified circumstances. These provisions could discourage other companies from trying to acquire E.mergent even though those other companies might be willing to offer greater value to E.mergent stockholders than ClearOne has offered in the merger. The payment of the termination fee could also have a material adverse effect on E.mergent's financial condition and results of operations. Risks Relating to ClearOne's Business ClearOne faces intense competition in the audio and videoconferencing industries, and its operating results will be harmed if ClearOne cannot compete effectively against other companies. The markets for ClearOne products and services are highly competitive. These markets include ClearOne's traditional dealer channel, the market for its conferencing services, and its retail channel. ClearOne competes with businesses having substantially greater financial, research and development, manufacturing, marketing, and other resources. ClearOne expects its competitors to continue to improve the performance of their current products or services, to reduce their current products or service sales prices and to introduce new products or services that may offer greater performance and improved pricing. To remain competitive, ClearOne is required to devote substantial resources to maintaining product and services offerings that include current technology and advance features, but it is possible these efforts will not be sufficient to keep pace with competitors' efforts to improve their technology and product features. If ClearOne is not able to continually design, manufacture, and successfully introduce new or enhanced products or services that are comparable or superior to those provided by other companies, ClearOne could experience pricing pressures and reduced sales, margin, profits, and market share, each of which could materially harm its business. Difficulties in estimating customer demand in its product segment could harm ClearOne's profit margins. Orders from ClearOne's resellers are based on demand from end-users. Prospective end-user demand is difficult to measure. This means that any period could be adversely impacted by low ClearOne end-user demand, which could in turn negatively affect orders ClearOne receives from resellers. ClearOne's 24

expectations for both short- and long-term future net revenues are based on its own estimates of future demand as well as backlog based on its blanket purchase order program in which certain dealers commit to purchase specified quantities of products over a twelve month period. ClearOne also bases expense levels on those revenue estimates. If ClearOne's estimates of sales are not accurate and it experiences unforeseen variability in its revenues and operating results, it will hamper ClearOne's ability to manage expense levels accordingly, thereby adversely affecting profit margins. ClearOne's profitability may be adversely affected by its continuing dependence on its distribution channels. ClearOne markets its products primarily through a network of dealers and master distributors. All of its agreements regarding such dealers and distributors are non-exclusive and terminable at will by either party. It cannot be assured that any or all such dealers or distributors will continue to offer ClearOne products. Price discounts to ClearOne's distribution channels are based on performance. However, there are no obligations on the part of such dealers and distributors to provide any specified level of support to ClearOne's products or to devote any specified time, resources or efforts to the marketing of ClearOne's products. There are no prohibitions on dealers or distributors offering products that are competitive with ClearOne's products. Most dealers do offer competitive products. ClearOne reserves the right to maintain house accounts, which are for products sold directly to customers. The loss of dealers or distributors could have a material adverse effect on ClearOne's business. ClearOne's reseller customer contracts are typically short-term and early terminations of its contracts may cause its revenues to decline and harm its profit margins. ClearOne does not typically enter into long-term contracts with its reseller customers, and ClearOne cannot be certain as to future order levels from its reseller customers. When ClearOne does enter into a long-term contract, the contract is generally terminable at the convenience of the customer. In the event of an early or unanticipated termination by one or more of ClearOne's larger reseller customers, it is unlikely that ClearOne will be able to rapidly replace that revenue source or rapidly reduce its expense levels to compensate for such loss of revenues, both of which would harm its net revenues and profit margins. Service interruptions could negatively affect revenues from ClearOne's conference calling service business. ClearOne relies heavily on its network equipment, telecommunications providers, data, and software to support all of its functions. ClearOne's conference calling services, which produced 29.3% of ClearOne's revenues during its last fiscal year, relies 100 percent on its network equipment for its revenues. ClearOne cannot guarantee that its back-up systems and procedures will operate satisfactorily in an emergency. Should ClearOne experience such a material failure of its equipment or the services of its telecommunications providers, it would substantially affect revenues and could seriously jeopardize ClearOne's ability to continue operations. In particular, should ClearOne's conference calling service experience even a short-term interruption of its network or telecommunication providers, ClearOne's ongoing customers may choose a different provider, and its reputation may be damaged, reducing its ability to retain current customers and attract new customers. ClearOne depends on a limited number of suppliers for components and the inability to obtain sufficient components could adversely affect its product sales. Certain electronic components used in connection with ClearOne's products can only be obtained from single manufacturers and ClearOne is dependent upon the ability of these manufacturers to deliver such components to its suppliers so that they can meet ClearOne's delivery schedules. ClearOne does not have a written commitment from such suppliers to fulfill ClearOne's future requirements. ClearOne's suppliers maintain an inventory of such components, but ClearOne has no assurance that such components will always be readily available, available at reasonable prices, available in sufficient quantities, or deliverable in a timely fashion. If such key components become unavailable, it is likely that ClearOne will experience delays, which could be significant, in production and delivery of its products unless and until ClearOne can otherwise procure the required component or components at competitive prices, if at all. The lack of availability of these components could have a materially adverse effect on ClearOne ability to sell products. ClearOne has experienced long component lead times in the past, but it is experiencing improved lead times on many products. Even though ClearOne has purchased more of these "longer-lead-time" parts to ensure continued delivery of products, reduction in these inventories has tracked with the reduction of lead times. Suppliers of some of these components are currently or may become competitors of ClearOne, which might also affect the availability of key components to ClearOne. It is possible that other components required in the 25

future may necessitate custom fabrication in accordance with specifications developed or to be developed by ClearOne. Also, in the event ClearOne, or any of the manufacturers whose products ClearOne expects to utilize in the manufacture of its products, are unable to develop or acquire components in a timely fashion, ClearOne's ability to achieve production yields, revenues and net income may be adversely affected. Product development delays could harm ClearOne's competitive position and reduce its revenues. ClearOne may experience technical difficulties and delays with the development and introduction of new products. The products developed by ClearOne involve sophisticated and complicated components and manufacturing techniques involving new technologies. Potential difficulties in the development process that could be experienced by ClearOne include difficulty in meeting required specifications, hiring a sufficient number of developers, discovery of software bugs, and achieving necessary manufacturing efficiencies. ClearOne has experienced product development delays associated with its video conferencing products. If ClearOne is not able to manage and minimize such potential difficulties, its sales could be negatively affected. Delays in the distribution process could have an adverse effect on ClearOne's sales. ClearOne's sales results are dependent in part on its ability to provide prompt, accurate, and complete services to customers on a timely and competitive basis. Delays in distribution in ClearOne's day-to-day operations or material increases in costs of procuring and delivering products could have an adverse effect on ClearOne's ability to generate revenues from product sales. Any failure of ClearOne's computer operating systems, the Internet or its telephone system could adversely affect its ability to receive and process customers' orders and ship products on a timely basis. Strikes, termination of air travel, or other service interruptions affecting Federal Express Corporation, United Parcel Service of America, Inc., or other common carriers used by ClearOne to receive necessary components or other materials or to ship its products also could impair its ability to deliver products on a timely and cost-effective basis. Such failures would likely negatively affect ClearOne's sales and net revenues. If ClearOne is unable to protect its intellectual property rights, its competitive position could be harmed or ClearOne could be required to incur expenses to enforce its rights. ClearOne currently relies primarily on a combination of trade secrets, copyrights, trademarks, and nondisclosure agreements to establish and protect its proprietary rights in its products. ClearOne cannot assure that others will not independently develop similar technologies, or duplicate or design around aspects of its technology. ClearOne believes that its products and other proprietary rights do not infringe upon any proprietary rights of third parties. ClearOne cannot assure you, however, that third parties will not assert infringement claims in the future. Such claims could divert ClearOne's management's attention and be expensive, regardless of their merit. In the event of a claim, ClearOne might be required to license third party technology or redesign its products, which may not be possible or economically feasible. Existing directors and officers can exert considerable control over ClearOne. The officers and directors of ClearOne together had beneficial ownership of approximately 21.5% of its common stock (including options that are currently exercisable or exercisable within sixty (60) days) as of March 1, 2002. Assuming the ClearOne officers' and directors' actual beneficial ownership remained unchanged until completion of the merger, together they would have beneficial ownership of approximately 19.8% of ClearOne's common stock after the merger. This significant holding in the aggregate places the officers and directors in a position, when acting together, to have substantial control over ClearOne and could delay or prevent a change in control. International sales are accounting for an increasing portion of ClearOne's net revenue, and risks inherent in international sales could harm its profitability. International sales represent a significant portion of ClearOne's total revenue from continuing operations. For example, international sales represented 13% of its total sales from continuing operations for fiscal 2001 and 12% for fiscal 2000. ClearOne's international business is subject to the financial and operating risks of conducting business internationally, including: unexpected changes in, or imposition of, legislative or regulatory requirements; fluctuating exchange rates, tariffs and other barriers; difficulties in staffing and managing foreign subsidiary operations; export restrictions; greater difficulties in accounts receivable collection and longer payment cycles; potentially adverse tax consequences; and, potential hostilities and changes in diplomatic and trade relationships. 26

ClearOne's sales in the international market are denominated in U.S. Dollars and ClearOne EuMEA transacts business in U.S. Dollars, however, its financial statements are prepared in the Euro, according to German accounting principles. Although conversion to the Euro has eliminated currency exchange rate risk for transactions between the member countries, consolidation of ClearOne EuMEA's financial statements with those of ClearOne, under United States generally accepted accounting principles, requires remeasurement to U.S. Dollars which is subject to exchange rate risks. ClearOne currently does not undertake any hedging activities that might protect against such risks. The continued integration of ClearOne's subsidiaries and the integration of any additional acquired businesses involve uncertainty and risk. Following the acquisition of Ivron Systems in October 2001, ClearOne has dedicated substantial management resources in order to achieve the anticipated operating efficiencies from integrating Ivron Systems with ClearOne. The merger with E.mergent will result in additional demands on management resources that could prolong or adversely affect the successful integration of Ivron Systems. In addition, ClearOne intends to pursue acquisition opportunities in the future. The integration of such acquired businesses could require substantial management resources. There can be no assurance that any such integration will be accomplished without having a short or potentially long-term adverse impact on the business, results of operations or financial condition of ClearOne or that the benefits expected from any such integration will be fully realized. 27

In evaluating the merger agreement and the merger, you should carefully consider the discussion of risks and uncertainties discussed in the Risk Factor section. 28

THE E.MERGENT SPECIAL MEETING General E.mergent is furnishing this document to all stockholders of record of E.mergent common stock in connection with the solicitation of proxies by the E.mergent board of directors for use at the special meeting of E.mergent stockholders to be held on May 31, 2002. This document also is being furnished by ClearOne to E.mergent stockholders as a prospectus for ClearOne common stock to be issued in connection with the merger. Date, Place, and Time The special meeting will be held at 10:00 a.m., local time, on May 31, 2002, at E.mergent's offices located at 6110 Golden Hills Drive, Golden Valley, MN 55416. Purpose of Special Meeting At the special meeting, E.mergent stockholders will be asked: 1. to consider and vote upon a proposal to adopt and approve the merger agreement and approve the merger; and 2. to transact other business that may properly come before the special meeting. A copy of the merger agreement is attached to this document as Annex A. E.mergent stockholders are encouraged to read the merger agreement in its entirety and the other information contained in this document carefully before deciding how to vote. Under Delaware law, stockholders can consider at the special meeting only the matters contained in the notice for the special meeting. Record Date for the Special Meeting The E.mergent board of directors has fixed the close of business on April 5, 2002, as the record date for determination of E.mergent stockholders entitled to notice of and to vote at the special meeting. Voting Rights; Quorum E.mergent has one class of common stock outstanding, which has a par value of $.01 per share. Each holder of E.mergent common stock outstanding on the record date is entitled to one vote for each share held. The holders of a majority of the outstanding shares of E.mergent capital stock entitled to vote must be present at the special meeting, in person or by proxy, to constitute a quorum to transact business. Required Vote; Abstentions and Broker Non-Votes As a condition to completion of the merger, the Delaware General Corporation Law and the merger agreement require that the holders of a majority of all the outstanding shares of E.mergent common stock as of the record date must vote in favor of the merger and merger agreement in order to approve the merger. On the record date, 5,931,280 shares of E.mergent common stock were outstanding, held by approximately 280 holders of record. As of the close of business on the record date for the special meeting of E.mergent stockholders at which the merger agreement and the merger will be presented and voted upon, directors and executive officers of E.mergent (and their respective affiliates) collectively owned approximately 41% of the outstanding shares of E.mergent common stock entitled to vote at the special meeting on the merger agreement and the merger. This does not include 342,000 shares of E.mergent common stock issuable upon the exercise of presently exercisable options which these directors and officers beneficially own. Four of E.mergent's directors and one officer, holding 2,393,800 shares (approximately 40% of the outstanding shares of E.mergent common stock) have entered into voting agreements and delivered irrevocable proxies, pursuant to which they have agreed to vote their E.mergent shares in favor of adoption and approval of the merger agreement and approval of the merger, in favor of any matter that could reasonably be expected to facilitate the merger, and against 29

any matter which could reasonably be expected to result in a breach by E.mergent of the merger agreement or which could reasonably be expected to result in E.mergent's obligations under the merger agreement to fail to be satisfied. Abstentions will be treated as shares present in determining whether E.mergent has a quorum for the special meeting, but will not be voted. Accordingly, abstentions will have the same effect as a vote against approval of the merger. In addition, the failure of an E.mergent stockholder to return a proxy will have the effect of a vote against the proposal to adopt and approve the merger agreement and to approve the merger. Under the rules that govern brokers who have record ownership of shares that are held in "street name" for their clients, who are the beneficial owners of the shares, brokers have discretion to vote these shares on routine matters but not on non-routine matters. The adoption and approval of the merger agreement and the approval of the merger at the special meeting are not considered routine matters. Accordingly, brokers will not have discretionary voting authority to vote your shares at the special meeting. A "broker non-vote" occurs when brokers do not have discretionary voting authority and have not received instructions from the beneficial owners of the shares. At the special meeting, broker non-votes will be counted for the purpose of determining the presence of a quorum but will not be counted for the purpose of determining the number of votes cast on the merger agreement and the merger. Accordingly, at the special meeting, broker non-votes will have the same effect as a vote against the proposal to adopt and approve the merger agreement and to approve the merger. Consequently, E.mergent stockholders are urged to return the enclosed proxy card marked to indicate their vote. The board of directors of ClearOne has approved the merger and the issuance of shares of ClearOne common stock in the merger. See "The Merger and Related Transactions - Background of the Merger." Utah law does not require that ClearOne's stockholders approve the merger. Recommendation of the Board of Directors of E.mergent The E.mergent board of directors has determined that the merger is advisable, in the best interests of E.mergent stockholders and on terms that are fair to the stockholders of E.mergent. Accordingly, except for one director who abstained due to a conflict of interest, the E.mergent board of directors has unanimously approved the merger agreement and the merger and recommends that stockholders vote "FOR" adoption and approval of the merger agreement and approval of the merger. The director who abstained chose to do so because he was previously employed by E.mergent's financial advisor, who rendered an opinion on the fairness of the merger as described below. See "The Merger and Related Transactions- Interests of E.mergent's Directors and Officers in the Merger" for a discussion of conflicts of interest that certain directors and members of management may have in connection with the merger. Dissenters Rights of Appraisal Under Delaware law, holders of E.mergent common stock that comply with the applicable statutory procedures under Delaware law will be entitled to appraisal rights and to receive payment in cash for the fair value of their shares as determined by the Delaware Chancery Court. A summary of the applicable requirements of Delaware law is contained in this proxy statement/prospectus under the caption "The Merger and Related Transactions - Dissenters Rights of Appraisal ." In addition, the text of the applicable provisions of the Delaware General Corporate Law is attached as Annex D.

THE MERGER AND RELATED TRANSACTIONS This section of the proxy statement/prospectus and the following two sections entitled "Agreement and Plan of Merger" and "Ancillary Agreements" contain descriptions of the material aspects of the merger and related transactions, including the merger agreement and certain other agreements entered into in connection therewith. While we believe that the following description covers the material terms of the merger, the merger agreement and the related transactions and agreements, the description may not contain all of the information that is important to you. You should read carefully this entire document and the other documents that we refer to for a more complete understanding of the merger and the related transactions. Background of the Merger The terms of the merger agreement are the result of arm's-length negotiations between representatives of ClearOne and E.mergent. The following is a brief discussion of the background of these negotiations, the merger and related transactions: During 2001, E.mergent's board of directors and senior management explored methods of enhancing shareholder value through internal growth in the videoconferencing channel, raising new capital, development of the audiovisual channel, the acquisition of technology or acquiring other conferencing services companies. In July 2001, the CEO of E.mergent, Jim Hansen, and one of its directors approached a substantial industry partner concerning expanding its existing supplier relationship, forming a joint venture or having the partner acquire E.mergent due to the growing importance of the relationship. The companies conducted a video call on August 30, 2001, further discussing potential synergies, and senior technical officers of both companies met to explore their respective plans. This party continued its discussions with E.mergent, signing a confidentiality agreement in October 2001 as described below. In late August 2001, the CEO of E.mergent was approached by a director of a public company, not in the audio-visual industry, about the interest or willingness of E.mergent to consider being acquired. That discussion was very preliminary in nature and no further discussions with this company occurred. During the first week of September 2001, the CEO of E.mergent discussed with E.mergent's board of directors the possibility of engaging in more serious business combination discussions with both companies. The discussions held with these companies regarding possible acquisitions of E.mergent suggested to the CEO and E.mergent's board that such interest in acquiring E.mergent increased the likelihood of maximizing shareholder value through an acquisition rather than internal growth. Following the events of September 11, 2001, management and the board of directors of E.mergent determined that it was in the best interests of shareholders to explore strategic alternatives, including the possible sale of E.mergent. The Board concluded this because it believed that the events of September 11, 2001 would further slow the economy and reduce the availability of investment capital, making it more difficult to maximize shareholder value through internal growth. Thereafter, E.mergent interviewed several investment banking firms and on September 28, 2001, E.mergent engaged Goldsmith, Agio, Helms on an exclusive basis to explore various strategic alternatives for E.mergent, including the sale of E.mergent to a third-party. E.mergent selected Goldsmith, Agio, Helms because of their extensive experience representing selling companies of a size similar to E.mergent and the presence of their principal office in Minneapolis. In addition, one of E.mergent's directors was a managing director of Goldsmith, Agio, Helms at that time, and the E.mergent board was familiar with many of its principals. In connection with its engagement, Goldsmith, Agio, Helms prepared a Confidential Executive Summary and worked with E.mergent's senior management team to prepare a list of potential buyers. In early to mid October 2001, Goldsmith, Agio, Helms contacted a select group of potential buyers regarding their interest in acquiring E.mergent. The parties that were approached were believed to have both strategic interest and the financial ability to consummate a transaction. As part of this effort, Robin Sheeley, the Chief Technical Officer of E.mergent, telephoned the CEO of ClearOne, Frances Flood, on October 10 and they discussed very briefly whether ClearOne had an interest in acquiring E.mergent. After that conversation, ClearOne asked Wedbush Morgan Securities, Inc. to initiate a preliminary review of E.mergent and to handle preliminary discussions about a potential acquisition with Goldsmith, Agio, Helms. Six of the potential buyers Goldsmith, Agio, Helms contacted, including ClearOne, subsequently signed Confidentiality Agreements to permit the exchange of confidential information for the purpose of evaluating the merits of a potential acquisition of E.mergent. ClearOne entered into its Confidentiality 32

Agreement with E.mergent on October 10, 2001. Shortly after signing the Confidentiality Agreements, Goldsmith, Agio, Helms distributed the Confidential Executive Summary to the six potential buyers, including ClearOne. After further review of the opportunity, one of the other potential buyers declined to further participate in any discussions regarding an acquisition of E.mergent. After receiving the Confidential Executive Summary on or about October 12, ClearOne began its review of the summary and other publicly available information on E.mergent. On October 23, 2001, five of the potential buyers who executed Confidentiality Agreements, including ClearOne, met with E.mergent's senior management team at the Telcom Conference in Anaheim, California. Two of these buyers expressed interest in buying one of E.mergent's divisions rather than the entire company. E.mergent, with the advice of Goldsmith, Agio, Helms, decided to terminate further discussions with these two buyers as the sale of a division could adversely impact the future of the remaining parts of E.mergent's business and could also result in significant tax expenses to E.mergent. The October 23, 2001 meeting between E.mergent and ClearOne was attended by: Frances Flood, Randy Wichinski, CFO of ClearOne, and Gene Kuntz, COO of ClearOne; Michael Gardner and Robert Cherry from Wedbush Morgan Securities; Jim Hansen, Robin Sheeley, and Jill Larson, the Vice President of Administration, from E.mergent; and Jerry Caruso and Roger Redmond from Goldsmith, Agio, Helms. The participants discussed some of the key characteristics of both companies and opportunities within the industry in general. A follow-up meeting for the first week of November was discussed and subsequently, over the next several days, scheduled for November 6. Following the meetings in Anaheim, California in late October and early November 2001, E.mergent's senior management team and Goldsmith, Agio, Helms held additional meetings with three of the remaining potential buyers, including ClearOne on November 6. On that date, Frances Flood, Randy Wichinski, and Robert Cherry met with Jim Hansen, Robin Sheeley and Jill Larson at the E.mergent corporate offices and continued discussions regarding the potential benefits of the proposed acquisition, including a presentation by E.mergent covering the product and marketing opportunities possible from the proposed combination of the two companies. In late November and early December, E.mergent and Goldsmith, Agio, Helms held subsequent meetings and video conference calls with the three remaining potential buyers, including ClearOne. Meetings and calls with ClearOne involved further discussions regarding E.mergent's business, recent financial results, and financial prospects, as well as aspects of the possible transaction, including possible transaction structures and price. Also during this period, E.mergent and ClearOne continued to exchange additional information about their respective companies. ClearOne continued its investigation of E.mergent. On December 4, 2001, at the request of ClearOne management, Wedbush Morgan Securities provided ClearOne with certain financial analyses regarding the potential acquisition of E.mergent. On December 7, 2001, Wedbush Morgan Securities delivered to E.mergent, for discussion purposes only, a tentative proposal on behalf of ClearOne for the acquisition of E.mergent. On December 10, 2001, one other potential buyer made a proposal to purchase E.mergent. That proposal was verbal and not at a specific price but rather a range of multiples of E.mergent's earnings. There was no definition of what the potential buyer meant by "earnings." The proposal also did not contain a cash component. Because E.mergent had received specific proposals and was considering them, and to avoid concerns regarding premature disclosure of the proposed acquisition, on December 12, 2001, E.mergent issued a press release stating that it had engaged Goldsmith, Agio, Helms to explore strategic options. Between December 12, 2001 and December 18, 2001, E.mergent focused its negotiations with ClearOne, as ClearOne appeared to represent the best potential transaction to E.mergent's shareholders. The negotiations with ClearOne involved further discussion of the structure of the transaction and the consideration offered by ClearOne. ClearOne's proposal was determined to be superior due to its strategic fit with E.mergent, ClearOne's desire to rapidly consummate a transaction, and because ClearOne's proposal was superior both in value and structure, due to the potentially tax-free exchange of stock component to its proposal. Strategically, ClearOne and E.mergent would be able to sell each other's products in their respective distribution channels. ClearOne sold more equipment in the audio visual channel than the other potential buyer and that offered more opportunity for cross selling products. This was viewed as a considerable advantage. Also, E.mergent's board, with the advice of its financial advisor, concluded that the price range proposed by the other prospective buyer was likely to result in a price that was less than the specific price proposed by ClearOne. The board concluded that considerable negotiation of both the specific multiple and the definition of E.mergent's "earnings" was likely. ClearOne's proposal did not depend on a definition of "earnings" to which a multiple would be applied. 33

During this period of time, E.mergent also received an unsolicited inquiry by an institutional investor interested in potentially investing $10 million for newly issued E.mergent stock with the proceeds to be used for internal growth. This proposal was verbal and nonspecific with regard to terms and conditions. None of the investment proceeds were to go to existing stockholders. E.mergent had undertaken no due diligence with respect to this potential investor and was on the verge of signing an exclusivity agreement with ClearOne. For these reasons, E.mergent decided not to proceed with further discussions with this institutional investor until it determined whether or not a satisfactory transaction could be negotiated with ClearOne. On December 18, 2001, E.mergent entered into an exclusivity agreement with ClearOne. Pursuant to this agreement, E.mergent agreed to cease all acquisition negotiations with all other parties and to negotiate exclusively with ClearOne for 30 days. Shortly thereafter, ClearOne and E.mergent began negotiation of the specific terms of a transaction and the definitive merger agreement and exchanged drafts of the proposed definitive agreement. On December 27, 2001, Randy Wichinski met with Jim Hansen and Jill Larson at E.mergent corporate headquarters in Minneapolis to initiate a formal due diligence process. On December 28, 2001, the ClearOne board of directors met in person and by telephone with members of ClearOne management and representatives of Jones Waldo Holbrook & McDonough, P.C., ClearOne's legal counsel, to discuss the status of the proposed transaction with E.mergent and ClearOne management's due diligence findings to date. On January 3 and 4, 2002, members of ClearOne's management and representatives of ClearOne's independent auditors, Ernst & Young LLP, a representative of Jones Waldo, Holbrook & McDonough, P.C. and a representative from Wedbush Morgan Securities visited E.mergent's offices and also met with E.mergent's independent auditors, Deloitte & Touche LLP, to conduct business, financial, accounting tax, and legal due diligence and participate in discussions with E.mergent management, E.mergent's legal counsel and its independent auditors on various issues. Between January 4 and January 18, ClearOne continued its investigation and analysis of E.mergent, requesting additional information from E.mergent. Also during this period, ClearOne and E.mergent continued negotiation of the definitive merger agreement. On January 17, 2002, E.mergent and ClearOne essentially completed their negotiations with respect to the merger agreement. On that date, the ClearOne board of directors met telephonically, together with representatives of Jones Waldo Holbrook & McDonough P.C. and Robert Cherry of Wedbush Morgan Securities, to informally discuss in detail the terms and negotiations of the definitive merger agreement and the final results of ClearOne management's due diligence investigation. On January 18, 2002, E.mergent's board of directors conducted a meeting at which, among other things, Goldsmith, Agio, Helms delivered its opinion as to the fairness, from a financial point of view, of the proposed merger consideration. The board of directors approved the merger agreement with ClearOne. On January 21, 2002, ClearOne's board of directors held a meeting attended by ClearOne management and legal counsel from Jones Waldo Holbrook & McDonough. After reviewing in further detail the proposed acquisition and the terms and conditions of the merger agreement, the ClearOne board of directors approved the merger agreement with E.mergent. On January 21, 2002, ClearOne and E.mergent executed the Merger Agreement and certain E.mergent shareholders executed the related Voting Agreement, Irrevocable Proxies and Affiliate Agreements. ClearOne and E.mergent issued separate press releases early in the morning on January 22, 2002 announcing execution of the merger agreement. E.mergent's Reasons for the Merger The board of directors of E.mergent has determined that the terms of the merger and the merger agreement are fair to, and in the best interests of, E.mergent and its stockholders. In reaching its decision, E.mergent `s board of directors consulted with senior management and E.mergent `s financial and legal advisors and considered the material factors set forth below in reaching its decision to approve the merger agreement and the transactions contemplated by the merger agreement, and to recommend that E.mergent `s stockholders vote FOR adoption and approval of the merger agreement and approval of the merger: o the merger was viewed as a quicker and more certain method to enhance shareholder value than E.mergent's strategic alternatives, each of which involved a considerable degree of uncertainty of success, including raising additional capital, acquisition of E.mergent by another party, a merger of equals or a joint venture with another party; 34

o the difficulties, due to E.mergent's relatively small size and limited resources, in independently responding successfully to pervading competitive factors in the audio and videoconferencing industry, including the cost of developing sales channels, pricing competition and the need to develop complete product lines in order to compete; o the overall strategic fit between E.mergent and ClearOne in view of their respective product lines, markets, and distribution channels and the potential synergies, efficiencies, and cost savings that could be realized through a combination of E.mergent and ClearOne; o the opportunity for E.mergent shareholders to continue equity participation in a larger, more diversified audio and videoconferencing company at a premium over market prices for E.mergent common stock prior to announcement of the merger; o the financial advice provided to E.mergent by Goldsmith, Agio, Helms and its opinion that the consideration to be received by E.mergent shareholders in the merger is fair from a financial point of view; o the advice of its accounting and legal advisors that the merger is expected to be a partially tax-free and partially taxable transaction for federal income tax purposes to E.mergent shareholders receiving ClearOne common stock--in this regard, E.mergent `s board of directors considered the possibility that all the merger consideration could be taxable to E.mergent's shareholders under certain circumstances; and o the terms and conditions of the merger agreement, which were viewed to be fair to E.mergent and its shareholders. E.mergent's board of directors also identified and considered a number of uncertainties and risks in its deliberations concerning the merger, including the following: o the risk that the potential benefits sought in the merger may not be fully realized, if at all; o the risk of management and employee disruption as a result of the merger, including the risk that key personnel may choose not to remain employed with the combined company; and o other applicable risks associated with the businesses of E.mergent and ClearOne described in this proxy statement/prospectus. The foregoing discussion of the information and factors considered by E.mergent `s board of directors includes all material factors considered by the E.mergent board of directors. In view of the variety of factors considered in connection with its evaluation of the merger, E.mergent `s board of directors did not find it practicable to, and did not, quantify or otherwise assign relative or specific weight or values to any of these factors, and individual directors may have given different weights to different factors. Opinion of E.mergent's Financial Advisor Goldsmith, Agio, Helms has acted as E.mergent's exclusive financial advisor in connection with the proposed merger. E.mergent selected Goldsmith, Agio, Helms based on Goldsmith, Agio, Helms' experience, expertise, and reputation. Goldsmith, Agio, Helms is a nationally recognized investment banking firm which, as a customary part of its business, is engaged in the valuation of businesses and securities in connection with mergers and acquisitions, private placements, and valuations for corporate and other purposes. In connection with Goldsmith, Agio, Helms' engagement, E.mergent requested that Goldsmith, Agio, Helms evaluate the fairness, from a financial point of view, to the holders of E.mergent common stock of the merger consideration. On January 18, 2002, at a meeting of the E.mergent board of directors held to evaluate the merger, Goldsmith, Agio, Helms delivered to the E.mergent board of directors an oral opinion, which was confirmed thereafter by delivery of a written opinion dated January 18, 2002, to the effect that, as of such date, and based upon and subject to the assumptions, procedures, and limitations set forth therein, the proposed merger consideration was fair, from a financial point of view, to the holders of E.mergent common stock. The full text of Goldsmith, Agio, Helms' written opinion, dated January 18, 2002, to the E.mergent board of directors, which sets forth the procedures followed, assumptions made, matters considered, and limitations on the review 35

undertaken, is attached to this document as Annex C and is incorporated into this document by reference. You are urged to read the Goldsmith, Agio, Helms opinion in its entirety. The description of the Goldsmith, Agio, Helms opinion set forth in this proxy statement/prospectus is qualified in its entirety by reference to the full text of such opinion. Goldsmith, Agio, Helms' opinion is rendered for the benefit and use of the board of directors of E.mergent in connection with the board of directors' consideration of the merger, relates only to the fairness of the merger consideration from a financial point of view, does not address any other aspect of the merger or any related transaction and does not constitute a recommendation to any holder of E.mergent common stock with respect to any matters, including the shareholder vote, relating to the proposed merger. In arriving at its opinion, Goldsmith, Agio, Helms undertook such reviews, analyses, and inquiries as it deemed necessary and appropriate under the circumstances. Among other things, Goldsmith, Agio, Helms: o reviewed the latest draft of the merger agreement made available to Goldsmith, Agio, Helms, dated January 17, 2002, and assumed that the final form of the merger agreement would not vary in any material respect from the January 17th draft, and that the terms of the consideration to be paid to the holders of E.mergent common stock will be identical to those set forth in the January 17th draft; o reviewed certain financial and other information that is publicly available relating to E.mergent; o reviewed certain financial and other information that is publicly available relating to ClearOne; o reviewed certain internal financial and operating data of E.mergent that was made available to Goldsmith, Agio, Helms by E.mergent; o discussed with senior management of E.mergent the financial condition, operating results, business outlook and prospects of E.mergent; o discussed with senior management of ClearOne the present financial condition, operating results, and near term business outlook of ClearOne; o reviewed E.mergent's and ClearOne's historical common stock price trends; o analyzed the stock price premiums paid in recent mergers and acquisitions of publicly traded companies with transaction values ranging from $10 to $50 million, and compared those premiums to the premium implied by the consideration in the proposed merger; o performed a discounted cash flow analysis of E.mergent's projected financial performance as a stand-alone entity, based on financial projections that E.mergent management provided to Goldsmith, Agio, Helms; o reviewed the valuations of publicly traded companies that Goldsmith, Agio, Helms deemed generally comparable (for such purposes) to E.mergent; and o reviewed the financial terms of certain transactions Goldsmith, Agio, Helms deemed comparable to the merger that recently have been effected. In arriving at its opinion, Goldsmith, Agio, Helms relied upon and assumed, without independent verification, the accuracy and completeness of the financial statements and other information furnished by, or publicly available relating to, E.mergent or ClearOne, or otherwise made available to Goldsmith, Agio, Helms. Goldsmith, Agio, Helms also relied upon the representations and warranties of E.mergent and ClearOne contained in the merger agreement and have assumed, without independent verification, that they are true and correct. Goldsmith, Agio, Helms was not engaged to, and did not attempt to, or assume responsibility to, verify independently such information. Goldsmith, Agio, Helms further relied upon assurances by E.mergent that the information provided to Goldsmith, Agio, Helms had a reasonable basis, and with respect to projections and other business outlook information, reflected the best then-currently available estimates and judgments of future financial performance of E.mergent, and that E.mergent was not aware of any information or fact that would make the information provided to Goldsmith, Agio, Helms incomplete or misleading. Goldsmith, Agio, Helms also assumed that E.mergent and ClearOne each would perform all of the covenants and agreements to be performed by it under the merger agreement, that the conditions to the merger set forth in the merger agreement would be satisfied and that the merger would be consummated on a timely basis in the manner contemplated by the merger agreement. Goldsmith, 36

Agio, Helms also assumed that, once consummated, the merger would qualify as a partially tax-free reorganization for federal income tax purposes. In arriving at its opinion, Goldsmith, Agio, Helms did not perform any appraisals or valuations of specific assets or liabilities of E.mergent, nor was Goldsmith, Agio, Helms furnished with any such appraisals. The Goldsmith, Agio, Helms opinion is necessarily based upon the information available to Goldsmith, Agio, Helms and the facts and circumstances as they existed and are subject to evaluation on the date of the opinion, including the financial, economic, market and other conditions as in effect on the date of the opinion; events and conditions occurring or existing after the date of the opinion could materially affect the assumptions used in preparing the opinion. Goldsmith, Agio, Helms did not analyze the tax consequences of the merger, including tax consequences to any holder of E.mergent common stock. Goldsmith, Agio, Helms was not asked to, nor did it, express any opinion as to the relative merits of the merger as compared to any alternative business strategies that might exist for E.mergent, the effect of any other transaction in which E.mergent might engage, or the form of the merger agreement or the terms contained therein. Furthermore, Goldsmith, Agio, Helms expressed no opinion as to the prices at which either E.mergent or ClearOne stock may trade following the date of its opinion. Goldsmith, Agio, Helms' opinion was rendered as of the date thereof, and Goldsmith, Agio, Helms did not express any opinion as to whether, on or about the effective time of the merger, the merger consideration would be fair, from a financial point of view, to E.mergent's shareholders. The Goldsmith, Agio, Helms analyses set forth below are a complete description of the analyses performed by Goldsmith, Agio, Helms in arriving at its opinion. In arriving at its opinion, Goldsmith, Agio, Helms did not attribute any particular weight to any analysis or factor considered by it, but rather considered the results of its analyses as a whole. Accordingly, Goldsmith, Agio, Helms believes that its analyses and the summary set forth below must be considered as a whole and that selecting portions of its analyses, or of the summary, without considering all factors and analyses, could create an incomplete view of the processes underlying its analyses. The analyses performed by Goldsmith, Agio, Helms (and summarized below) are not necessarily indicative of actual values or actual future results, which may be significantly more or less favorable than suggested by such analyses. Additionally, analyses relating to the values of businesses do not purport to be appraisals or to reflect the prices at which businesses or securities actually may be sold. Accordingly, Goldsmith, Agio, Helms' analyses and estimates are inherently subject to substantial uncertainty. The type and amount of merger consideration payable pursuant to the merger was determined through negotiation between E.mergent and ClearOne. Although Goldsmith, Agio, Helms provided financial advice to E.mergent during the course of the negotiations, Goldsmith, Agio, Helms did not recommend the amount of the merger consideration or the payment or other terms thereof, and the decision to enter into the merger agreement was solely that of E.mergent's board of directors. Goldsmith, Agio, Helms' opinion as to the fairness of the merger consideration from a financial point of view was only one of many factors considered by the board of directors in making their determination to recommend adoption of the merger agreement, and should be not be viewed as determinative of the views of the E.mergent board of directors or management with respect to the proposed merger or the merger consideration payable in the merger. The following is a summary of the material financial analyses underlying Goldsmith, Agio, Helms' opinion dated January 18, 2002, delivered to the E.mergent board of directors in connection with the proposed merger. On that date, the closing prices of ClearOne and E.mergent common stock were $17.15 and $2.96, respectively. Discounted Cash Flow Analysis. Goldsmith, Agio, Helms performed a discounted cash flow analysis based on the projected five-year financial performance of E.mergent provided to Goldsmith, Agio, Helms by E.mergent management. E.mergent's weighted average cost of capital for purposes of this analysis was calculated to be approximately 19.2 %. Terminal values were calculated by applying alternative perpetual growth rates of 3.0 % to 4.5 % to the projected free cash flow in fiscal year 2006. Based on this analysis, E.mergent's implied per share equity values ranged from approximately $2.02 to $2.98. Discounted cash flow analysis is a widely-used valuation methodology, but it relies on numerous assumptions, including assets and earnings growth rates, terminal values, and discount rates. Analysis of Publicly Traded Comparable Companies. Goldsmith, Agio, Helms analyzed selected historical financial, operating, and stock market data of E.mergent, ClearOne, and other publicly traded companies that Goldsmith, Agio, Helms deemed to be comparable to E.mergent for this analysis. The five companies 37

(collectively, the "Comparable Companies") deemed by Goldsmith, Agio, Helms to be reasonably comparable to E.mergent in terms of products and services offered, markets served, and business prospects were: o InFocus Corporation; o Inter-Tel Inc.; o MCSi, Inc.; o Forgent Corporation (formerly VTEL Corporation); and o Wire One Technologies, Inc. Although E.mergent was included in the analysis for reference purposes, E.mergent was not included in any calculation of implied multiples for purposes of Goldsmith, Agio, Helms' analysis. No company utilized in the Comparable Company Analysis is identical to E.mergent. Accordingly, an analysis of the results of the foregoing necessarily involves complex considerations and judgments concerning the differences in financial and operating characteristics of E.mergent and other factors that could affect the public trading value of the comparable companies to which they are being compared. Goldsmith, Agio, Helms examined certain publicly available financial data of the Comparable Companies, including the ratio of enterprise value (equity value plus total debt, including preferred stock, less cash and cash equivalents) to latest-12-month ("LTM") revenue, earnings before interest, taxes, depreciation and amortization ("EBITDA"), and earnings before interest and taxes ("EBIT"). This analysis showed that the Comparable Companies had a multiple represented by the ratio of enterprise value to LTM revenue ranging from 0.7x to 2.4x, with a mean of 1.4x and a median of 1.1x; a multiple represented by the ratio of enterprise value to LTM EBIT ranging from 14.0x to 19.3x, with a mean of 15.9x and a median of 14.5x; and a multiple represented by the ratio of enterprise value to LTM EBITDA ranging from 11.0x to 12.7x, with a mean of 11.7x and a median of 11.5x. By applying the median ratios derived from the Comparable Company Analysis to E.mergent's estimated operating results for its LTM results ending September 30, 2001, E.mergent's implied range of equity value per share was calculated to be approximately $2.45 to $3.96. Analysis of Selected Merger and Acquisition Transactions. Goldsmith, Agio, Helms compared the proposed merger with selected comparable merger and acquisition transactions (the "Comparable Transaction Analysis"). No transaction analyzed in the Comparable Transaction Analysis is identical to the merger. Accordingly, an analysis of the results of the foregoing necessarily involves complex considerations and judgments concerning differences in financial and operating characteristics of E.mergent and other factors that could affect the acquisition value of the companies to which E.mergent is being compared. Goldsmith, Agio, Helms performed an analysis of 28 merger and acquisition transactions involving companies operating in the audio and video conferencing services and equipment and other related markets that occurred between November 1995 and January 2002. From the 28, Goldsmith, Agio, Helms selected eight that were deemed to be closely relevant. For the eight merger and acquisition transactions analyzed, the multiple represented by the ratio of enterprise value to LTM revenue ranged from 0.5x to 3.0x, with a mean of 1.5x and a median of 0.8x. The multiple represented by the ratio of enterprise value to LTM EBITDA was 8.7x. By applying the median ratios derived from the Comparable Transaction Analysis to E.mergent's estimated operating results for the LTM results ending September 30, 2001, E.mergent's range of implied equity value per share was calculated to be approximately $2.27 to $2.86. Acquisition Premiums Analysis. Goldsmith, Agio, Helms analyzed the premiums paid for approximately 150 publicly disclosed mergers and acquisitions of companies with enterprise values ranging from $10 to $50 million executed between January 2000 and December 2001. The mean and the median premium paid over the targets' stock prices 30 business days before the announcement date, five business days before the announcement date, and one business day before the announcement date were 50.4 % and 46.5 %, 44.9 % and 39.3 %, and 39.5 % and 33.1 %, respectively. The range on these transactions vary from negative premiums to premiums in excess of 130 %. 38

The per share price to be paid to E.mergent shareholders by ClearOne of approximately $3.47 (calculated based on ClearOne's share price as of the close of trading on January 16, 2002) represents a premium of 10.2 % over E.mergent's share price as of the close of trading on January 16, 2002, and a premium of 21.3% over E.mergent's share price as of the close of trading on December 11, 2001 (the date immediately prior to the date of the press release announcing the engagement of Goldsmith, Agio, Helms by E.mergent). Common Stock Trading History. Goldsmith, Agio, Helms' analysis of E.mergent's and ClearOne's common stock trading history consisted of historical analyses of the closing prices and volumes of E.mergent and ClearOne and the relative performance of E.mergent, ClearOne, the Dow Jones Industrial Average, and the S&P 500 Index. Goldsmith, Agio, Helms' analysis considered the high and low closing prices for E.mergent and ClearOne over the twelve-month period ended January 16, 2002. On December 14, 2001, E.mergent's common stock reached a twelve-month high closing price per share of $3.29 and on September 27, 2001, reached a twelve-month low closing price per share of $1.10. On October 10, 2001, ClearOne's common stock reached a twelve-month high closing price per share of $21.75 and on April 3, 2001, experienced a twelve-month low closing price per share of $9.63. Goldsmith, Agio, Helms also analyzed the volume of shares traded at various prices. For E.mergent's common stock, the volume-weighted average price per share for the twelve months ending on January 16, 2002 was $2.15. For ClearOne, the volume-weighted average price per share for the twelve months ending January 16, 2002 was $17.25. Miscellaneous. E.mergent has agreed to pay Goldsmith, Agio, Helms a fee for its financial advisory services in connection with the proposed merger based upon a percentage of the transaction value of the merger calculated upon the closing of the merger. Assuming the closing sales price of the ClearOne common stock is $17.20 on the day of the merger (which was the closing sales price on May 3, 2002), the fee payable to Goldsmith, Agio, Helms upon consummation of the merger would be approximately $775,780. Goldsmith, Agio, Helms received a non-contingent fee of $100,000 upon delivery to the E.mergent board of directors of its fairness opinion, which amount will be credited against the total fee to be paid by E.mergent to Goldsmith, Agio, Helms upon the closing of the merger. Goldsmith, Agio, Helms also received a one-time retainer of $50,000 following its engagement by E.mergent. E.mergent has agreed to reimburse Goldsmith, Agio, Helms for reasonable out-of-pocket expenses (up to a maximum of $10,000), including, but not limited to, fees and expenses of counsel, and to indemnify Goldsmith, Agio, Helms against liabilities and expenses arising out of its engagement. Roger Redmond, a current director or E.mergent, was employed by Goldsmith, Agio, Helms from June 1999 to December 2001, most recently as a Managing Director. Recommendation of E.mergent's Board of Directors The E.mergent board of directors believes that the merger is advisable and in the best interests of E.mergent and its stockholders. The E.mergent board, therefore, recommends that its stockholders vote FOR approval of the merger. See "The Merger and Related Transactions - Background of the Merger," "E.mergent's Reasons for the Merger," "Opinion of E.mergent's Financial Advisor," and "Material U.S. Federal Income Tax Consequences." Interests of E.mergent's Directors and Executive Officers in the Merger When you are considering the recommendation of E.mergent's board of directors with respect to approving the merger and the merger agreement, you should be aware that some of the directors and executive officers of E.mergent have interests in the merger and participate in arrangements that are different from, or are in addition to, those of E.mergent stockholders generally. The E.mergent board of directors was aware of these interests and considered them, among other matters, when it approved the merger and the merger agreement. These interests include the following: Options, Accelerated Vesting of Options and Bonus Shares The following directors and executive officers of E.mergent hold the total number of stock options indicated: James Hansen, Chairman and CEO, 130,000; Richard Craven, Director, 28,000; Robin Sheeley, Chief Technical Officer and Director, 35,000; Peter McDonnell, Director, 22,000; Roger Redmond, Director, 22,000; and Jill Larson, Vice President-Administration, 105,000. The vesting restrictions on all outstanding options held by directors and executive officers to purchase E.mergent stock will accelerate, thereby causing such stock options to become fully vested and exercisable immediately prior to the closing of the merger. The aggregate number of shares of E.mergent common stock issuable 39

upon the exercise of options held by directors and executive officers, that would become vested upon the merger is 13,333 shares held as follows: 10,000 shares held by Mr. Hansen at an exercise price of $3.37 per share, and 3,333 shares held by Ms. Larson at an exercise price of $1.47 per share. Pursuant to the terms of the merger agreement, all options to purchase E.mergent common stock will be assumed by ClearOne in the merger and converted into options to purchase ClearOne common stock. For further discussion about the treatment of E.mergent options in the merger, see the section entitled "Agreement and Plan of Merger - Stock Options" on page 49 of this document. Ms. Larson and Messrs. Hanson and Sheeley will also each receive approximately 689 shares of E.mergent common stock when the treasury shares of E.mergent common stock are issued to employees as a bonus prior to completion of the merger. Executive Employment Agreements ClearOne and E.mergent expect that upon the completion of the merger, Robin Sheeley, a director and the Chief Technical Officer of E.mergent, will become ClearOne's Chief Technology Officer. Based on discussions between Mr. Sheeley and ClearOne, they anticipate his employment with ClearOne will be on terms substantially similar to those of his current employment with E.mergent. The current executive employment agreement with E.mergent continues through August 2, 2002, and provides that it is to be automatically extended each year for additional one-year periods, unless E.mergent gives prior notice of non-renewal. His executive employment agreement provides that if, within six months following a merger, Mr. Sheeley's employment is terminated for any reason, other than for cause, or he voluntarily terminates his employment, then Mr. Sheeley is entitled to a severance payment that will be equal to the sum of his current annual base salary for twelve months, plus the last annual bonus from E.mergent. The severance payment generally would be made in equal installments over twelve months. As of January 1, 2000, E.mergent entered into an executive employment agreement with James Hansen, E.mergent's Chairman, Chief Executive Officer, President and Treasurer. The executive employment agreement continues through January 1, 2003, and provides that it is to be automatically extended each year for additional one-year periods, unless E.mergent gives prior notice of non-renewal. His executive employment agreement provides that if, within six months following a merger, Mr. Hansen's employment is terminated for any reason, other than for cause, or if his job responsibilities or authority are substantially reduced, then Mr. Hansen is entitled to a severance payment that will be equal to the sum of his current annual base salary for twelve months, plus the last annual bonus paid by E.mergent. The severance payment generally would be made in equal installments over twelve months. On January 1, 1998, E.mergent entered into an employment agreement with Jill Larson, E.mergent's Vice President-Administration and Corporate Secretary. The executive employment agreement continued through January 1, 2002, and provides that it is to be automatically extended each year for additional one-year periods, unless E.mergent gives prior notice of non-renewal. Such notice was not given by E.mergent during 2001, and Ms. Larson's employment agreement has been extended to January 1, 2003. Her executive employment agreement provides that if, within six months following a merger, Ms. Larson's employment is terminated for any reason, other than for cause, or she voluntarily terminates her employment, then Ms. Larson is entitled to a severance payment that will be equal to the sum of her current annual base salary for twelve months, plus the last annual bonus from E.mergent. The severance payment generally would be made in equal installments over twelve months. In the event that the employment of the executive officers is terminated immediately after the merger (as is currently anticipated for Mr. Hansen and Ms. Larson but not for Mr. Sheeley), it is estimated that, based on specific assumptions, the severance payments payable under these agreements, plus the value of the related benefits, would be approximately $189,000 to Mr. Hansen, $120,000 to Ms. Larson, and $160,000 to Mr. Sheeley. Indemnification and Directors and Officers Insurance E.mergent officers and directors are entitled to continuing indemnification against some liabilities by virtue of provisions contained in E.mergent's certificate of incorporation, and bylaws. In addition, the executive officers have continuing coverage by E.mergent's directors and officers liability insurance for acts arising during their tenure with E.mergent Consideration of the Merger by ClearOne's Board of Directors and Reasons for the Merger The ClearOne board of directors approved the merger agreement and the merger with E.mergent because it believes that the combined company has the potential to become a stronger conferencing products and services company in a growing and competitive market. In particular, the ClearOne board of directors believes that the acquisition will help position ClearOne to achieve its long-term operating and financial objectives, and reinforce its strategy of providing a comprehensive suite of conferencing products and services. In 40

addition, the ClearOne board of directors believes that the merger will allow the combined company the opportunity to realize the following anticipated benefits of the merger: o The ability to expand and enhance certain product lines of the combined company. For example, ClearOne's Gentner division plans to enhance its V-There(TM) videoconferencing products with a full line of other patented video equipment, from E.mergent's VideoLabs division. o The ability to utilize the other company's existing sales channels. For example, ClearOne will have the opportunity to sell ClearOne's line of video and audio products into E.mergent's established videoconferencing sales channel. In turn, ClearOne intends to use its existing sales channels to sell VideoLabs' products. o The ability to expand ClearOne's best-in-class technical team, which assists its dealer channel with service, support, and training, with E.mergent's Acoustic Communications Systems(TM) division, and which is anticipated to function as installation support to the existing dealer network of ClearOne's Gentner division. o The ability to bring ClearOne products and services, as well as new products and services that the combined company has the opportunity to produce, to E.mergent's customer base that currently uses other vendors for conferencing products and services. o The ability to expand ClearOne's management team through the addition of E.mergent's Chief Technical Officer Robin Sheeley, who will join ClearOne as Chief Technology Officer with responsibility for all research and product development. o The ability to have an expanded geographic representation with additional locations in Chicago, Illinois; Minneapolis, Minnesota; and Des Moines, Iowa. o The ability to broaden ClearOne's international distribution and expertise by gaining E.mergent's experience and distribution in international markets. o The ability to realize benefits from combining each company's proprietary intellectual property. The ClearOne board of directors also reviewed with its financial and legal advisors the specific terms and conditions of the merger agreement, including the representations, warranties and covenants and the conditions to each party's obligations to complete the merger. The ClearOne board of directors also received reports from its management and financial and legal advisors as to the results of the due diligence investigation of E.mergent, which was performed with the assistance of its financial and legal advisors, and determined that these reports did not disclose information that would preclude its approval of the merger. The ClearOne board of directors also considered the following risks and additional factors relating to the merger: o the risk that the benefits sought in the merger would not be fully achieved; o the risk that the merger would not be consummated; o possible post-merger resignations of E.mergent's management; o the risk that the stockholders of E.mergent would not approve of the merger; and o the other applicable risks described in this proxy statement/prospectus under "Risk Factors." The foregoing discussion of the factors considered by ClearOne's board of directors, while not exhaustive, includes the material factors considered by its board of directors. In view of the variety of factors considered in connection with its evaluation of the merger, ClearOne's board of directors did not find it practicable to, and did not, quantify or otherwise assign relative or specific weight or values to any of these factors, and individual directors may have given different weights to different factors. After taking into account these and other factors, the ClearOne board of directors unanimously determined that the merger agreement and the merger were in the best interests of ClearOne and its stockholders and that ClearOne should enter into the merger agreement and complete the merger. 41

Other Prior Contacts Between ClearOne and E.mergent Prior to the negotiations leading to the merger agreement described in this proxy statement/prospectus, E.mergent served as a dealer for some of ClearOne's products pursuant to an August 1998 room systems product dealer agreement between ClearOne and Acoustic Communications System. The agreement is a standard dealer agreement used by ClearOne for its other dealers, containing usual and customary responsibilities and conditions. During calendar year 2001, E.mergent purchased approximately $173,974 of products from ClearOne pursuant to the dealer agreement. Restrictions on Resale of ClearOne Common Stock The shares of ClearOne common stock to be issued in connection with the merger have been registered under the Securities Act and will be freely transferable under the Securities Act, except for shares of ClearOne common stock issued to any person who is deemed to be an "affiliate" of either ClearOne or E.mergent immediately prior to the consummation of the merger. Persons who may be deemed to be affiliates include individuals or entities that control, are controlled by, or are under common control of either of ClearOne or E.mergent and may include some of E.mergent's officers and directors, as well as E.mergent's principal stockholders. Affiliates may not sell their shares of ClearOne common stock acquired in connection with the merger except pursuant to: o an effective registration statement under the Securities Act covering the resale of those shares; o an exemption under paragraph (d) of Rule 145 under the Securities Act; or o any other applicable exemption under the Securities Act. ClearOne's registration statement on Form S-4, of which this document forms a part, does not cover the resale of shares of ClearOne common stock to be received by any person in the merger. This proxy statement/prospectus does not cover any resale of ClearOne common stock that you receive in the merger, and no person is authorized to make any use of this proxy statement/prospectus in connection with any such resale. Accounting Treatment of the Merger ClearOne intends to account for the merger using the "purchase" method. After the merger, the results of operations of E.mergent will be included in the consolidated financial statements of ClearOne. Material U.S. Federal Income Tax Consequences In the opinion of Fredrikson & Byron, P.A., counsel to E.mergent, and Jones, Waldo, Holbrook & McDonough, P.C., counsel to ClearOne, the following are the material U.S. federal income tax consequences of the merger, assuming that the merger is effected as described in the merger agreement and this proxy statement/prospectus and subject to the other assumptions, limitations, and qualifications described herein. If the value of ClearOne common stock exceeds $10.25 per share on the merger date, so that the aggregate value of the ClearOne common stock that is received by the E.mergent shareholders in the merger is greater than the aggregate value of the cash received by E.mergent shareholders in the merger, then o To the extent that you receive ClearOne common stock in exchange for E.mergent common stock, you will not recognize capital gain or loss, but you may recognize dividend income or capital gains with respect to the cash payment that you receive in exchange for each share of E.mergent common stock. The amount of your taxable gain will be calculated as follows: You will need to determine the total value of ClearOne stock and cash that you receive. This amount must be compared to your adjusted basis in your E.mergent stock. The excess of the total value of ClearOne stock and cash received over your adjusted basis in your E.mergent stock is your "realized gain." If the amount of cash you receive is less than your "realized gain," your taxable gain will be limited to the amount of cash received. If the cash received exceeds your "realized gain," then the amount of the "realized gain" will be your taxable gain. If the total value of ClearOne stock and cash received is less than your adjusted basis in E.mergent stock, you are not allowed to recognize a loss for tax reporting purposes. o To the extent that you receive cash in exchange for E.mergent common stock, the gain you recognize will be capital gain unless the exchange "has the effect of the distribution of a dividend" in which case you would generally have ordinary income. In order to determine whether the exchange has the effect of the distribution of a 42

dividend, your receipt of cash should be analyzed as if, first, you received solely ClearOne common stock in exchange for your E.mergent common stock and then the cash paid reduces your ClearOne common stock, in a taxable redemption, to the number of shares of ClearOne stock that you actually received. The deemed redemption will be treated as a sale or exchange of the shares and not the distribution of a dividend only if the deemed redemption of your ClearOne shares satisfies one or more of the provisions of Section 302(b) of the Internal Revenue Code. This determination is made separately for each shareholder of E.mergent. Assuming that the redemption satisfies the requirements of one or more of the provisions of Section 302(b) of the Internal Revenue Code and you have held your E.mergent shares for more than 12 months at the time of the merger, any gain on such redemption will be a long-term capital gain. o If the deemed redemption does not satisfy one or more of the provisions of Section 302(b) of the Internal Revenue Code, it will be treated as a distribution that is subject to Section 301 of the Internal Revenue Code. In such case, the cash proceeds will be treated first as a dividend (taxed as ordinary income) to the extent of E.mergent's accumulated earnings and profits at the time of the merger (on a pro rata basis taking into account other Section 301 distributions made by E.mergent during the year, including other deemed redemptions resulting from the merger that are treated as Section 301 distributions). To the extent the cash received exceeds your ratable share of accumulated earnings and profits, the excess will be treated as a capital gain. o The aggregate tax basis of the ClearOne common stock received by you in the merger (including any fractional shares of ClearOne common stock deemed received and exchanged for cash), will be equal to the aggregate adjusted tax basis of the E.mergent stock exchanged in the merger, reduced by any amount of cash that you receive in the merger for the E.mergent common stock surrendered, and increased by the amount of cash treated as a dividend and the amount recognized as a capital gain. o The holding period of the ClearOne common stock received by you in the merger will include the holding period of the E.mergent common stock surrendered in exchange for ClearOne common stock. o ClearOne and E.mergent will not recognize gain or loss solely as a result of the merger. Assuming that the value of ClearOne common stock exceeds $10.25 per share on the merger date and certain other assumptions, limitations, and qualifications described below, Fredrikson & Byron, P.A., at the request of E.mergent, has rendered an opinion that the merger will qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code. If, however, the merger is completed at a time when the value of the ClearOne stock declined below $10.25 per share so that the aggregate value of the ClearOne common stock that is received by the E.mergent shareholders is less than the aggregate value of the cash received by E.mergent shareholders in the merger, the merger may not qualify as a reorganization under Section 368(a) of the Internal Revenue Code. Additionally, the Internal Revenue Service could challenge the reorganization status of the merger. If the merger does not qualify as a reorganization under Section 368(a), for U.S. federal income tax purposes, gain or loss would generally be recognized equal to the difference between the value of the cash and stock received and the tax basis for the E.mergent shares that were exchanged. Any gain or loss will be a capital gain or loss (assuming shares are held as a capital asset). Any such capital gain or loss will be long-term if, as of the date of exchange, shares were held for more than one year, or will be short-term if, as of such date, shares were held for one year or less. An E.mergent shareholder's aggregate basis in the ClearOne common stock so received would equal its fair market value as of the closing of the merger and the holding period for such stock would begin the day after the closing of the merger. Under the merger agreement, ClearOne and E.mergent may choose to complete the merger even though the value of the ClearOne common stock declines below $10.25 and the merger does not qualify as a reorganization under Section 368(a) of the Internal Revenue Code. However, in the event that prior to the closing, ClearOne and E.mergent determine that due to such a decline in the value the merger would not qualify as a reorganization, and neither E.mergent nor ClearOne terminates the merger due to such a decline as allowed under the merger agreement, ClearOne and E.mergent intend to advise E.mergent's shareholders of such circumstances and resolicit their approval of the merger. Limitations on Opinions and Discussion. As noted earlier, the tax opinions described herein are subject to certain assumptions, relating to, among other things, the truth and accuracy of certain factual representations made by E.mergent and ClearOne, the consummation of the merger in accordance with the 43

terms of the merger agreement and applicable state law and completion of the merger at a time when the aggregate value of the ClearOne common stock that is received by the E.mergent shareholders is greater than the aggregate value of the cash received by E.mergent shareholders. Further neither E.mergent nor ClearOne will request a ruling from the Internal Revenue Service with regard to any of the U.S. federal income tax consequences of the merger. Furthermore, the tax opinions will not bind the Internal Revenue Service and, therefore, the Internal Revenue Service is not precluded from asserting a contrary position. The tax opinions and this discussion are based on currently existing provisions of the Internal Revenue Code, existing and proposed Treasury regulations, and current administrative rulings and court decisions. There can be no assurance that future legislative, judicial, or administrative changes or interpretations will not adversely affect the accuracy of the tax opinions or of the statements and conclusions set forth herein. Any such changes or interpretations could be applied retroactively and could affect the tax consequences of the merger. This discussion does not address all U.S. federal income tax considerations that may be relevant to certain E.mergent shareholders in light of their particular circumstances, or to shareholders subject to special rules under U.S. federal income tax law, including dealers in securities, banks, insurance companies, shareholders who do not hold their E.mergent common stock as capital assets, foreign persons, tax-exempt entities, or persons who are subject to the alternative minimum tax provisions of the Internal Revenue Code Furthermore, it does not address E.mergent shareholders who acquired their shares in connection with stock options or stock purchase plans or in other compensatory transactions. It also does not address the tax consequences of the merger under foreign, state, or local tax laws or the tax consequences of transactions effectuated prior or subsequent to or concurrently with the merger, whether or not such transactions are in connection with the merger, including, without limitation, transactions in which E.mergent common stock is acquired or ClearOne common stock is disposed of. Accordingly, E.mergent shareholders are urged to consult their own tax advisors as to the consequences of the merger, including the applicable federal, state, local, and foreign tax consequences to them in their particular circumstances. Governmental Approvals and Regulatory Requirements Under the merger agreement, we have agreed to use commercially reasonable efforts to obtain all required governmental approvals and fulfill all applicable regulatory requirements. We are not aware, however, of any material federal or state regulatory requirements or approvals required for completion of the merger, other than filing a certificate of merger in Delaware at or before the effective time of the merger. Dissenters' Rights of Appraisal E.mergent stockholders will be entitled to appraisal rights as a result of the merger under Section 262 of the Delaware General Corporate Law. Attached is the full text of Section 262 of the Delaware General Corporate Law as Annex D to this proxy statement/prospectus. The following summary of the provisions of Section 262 of the Delaware General Corporation Law is not intended to be a complete statement of its provisions and is qualified in its entirety by reference to the full text of that law, which is incorporated by reference. If the merger is completed, and a holder of E.mergent common stock (1) delivers to E.mergent, prior to the special meeting vote on the merger, written notice of an intention to exercise rights to appraisal of shares, (2) does not vote in favor of the merger and (3) follows the procedures set forth in Section 262, the holder will be entitled to be paid the fair value of the shares of E.mergent common stock as to which appraisal rights have been perfected. The fair value of shares of E.mergent common stock will be determined by the Delaware Court of Chancery, exclusive of any element of value arising from the merger. The shares of E.mergent common stock with respect to which holders have perfected their appraisal rights in accordance with Section 262 and have not effectively withdrawn or lost their appraisal rights are referred to in this section as the "dissenting shares." Appraisal rights are available only to the record holder of shares. If an E.mergent stockholder wishes to exercise appraisal rights but has a beneficial interest in shares which are held of record by or in the name of another person, such as a broker or nominee, the stockholder should act promptly to cause the record holder to follow the procedures set forth in Section 262 to perfect the stockholder's appraisal rights. A demand for appraisal should be signed by or on behalf of the stockholder exactly as the stockholder's name appears on the stockholder's stock certificates. If the shares are owned of record in a fiduciary capacity such as by a trustee, guardian or custodian, the demand should be executed in that capacity, and if the shares are owned of record by more than one person, as in a joint tenancy or tenancy in common, the demand should be executed by or on behalf of all joint owners. An authorized agent, including one or more joint 44

owners, may execute a demand for appraisal on behalf of a record holder; however, in the demand the agent must identify the record owner or owners and expressly disclose that the agent is executing the demand as an agent of the record owner or owners. A record holder such as a broker who holds shares as nominee for several beneficial owners may exercise appraisal rights of the shares held for one or more beneficial owners and not exercise rights of the shares held for other beneficial owners. In this case, the written demand should state the number of shares for which appraisal rights are being demanded. When no number of shares is stated, the demand will be presented to cover all shares of record by the broker or nominee. If an E.mergent stockholder demands appraisal of the stockholder's shares under Section 262 and fails to perfect, or effectively withdraws or loses, the stockholder's right to appraisal, the stockholder's shares will be converted into a right to receive cash and a number of shares of ClearOne common stock in accordance with the terms of the merger agreement. Dissenting shares lose their status as dissenting shares if: o the merger is abandoned; o the dissenting stockholder fails to make a timely written demand for appraisal; o the dissenting shares are voted in favor of adoption of the merger or the merger agreement; o no petition for appraisal is filed with the Court of Chancery within 120 days after the effective date of the merger; o the dissenting stockholder fails to hold the dissenting shares on the date of the demand through the effective date of the merger; or o the dissenting stockholder delivers to ClearOne within 60 days of the effective date of the merger, or thereafter with ClearOne's approval, a written withdrawal of the stockholder's demand for appraisal of the dissenting shares, although no appraisal proceeding in the Delaware Court of Chancery may be dismissed as to any stockholder without the approval of the court. Failure to follow the steps required by Section 262 of the Delaware General Corporation Law for perfecting appraisal rights may result in the loss of the stockholder's appraisal rights, in which event a stockholder will be entitled to receive the consideration with respect to the stockholder's dissenting shares in accordance with the merger agreement. In view of the complexity of the provisions of Section 262 of the Delaware General Corporation Law, if a stockholder is considering objecting to the merger should that option become available, the stockholder should consult the stockholder's own legal advisor. Within ten days after the effective date of the merger, ClearOne must mail a notice to all stockholders who have complied with (1) and (2) above notifying such stockholders of the effective date of the merger. Within 120 days after the effective date, holders of E.mergent common stock may file a petition in the Delaware Court of Chancery for the appraisal of their shares, although they may, within 60 days of the effective date, withdraw their demand for appraisal. Within 120 days of the effective date, the holders of dissenting shares may also, upon written request, receive from ClearOne a statement setting forth the aggregate number of shares with respect to which demands for appraisals have been received. Description of ClearOne Capital Stock The authorized capital stock of ClearOne consists of 50,000,000 shares of common stock, $0.001 par value. As of the close of business on May 3, 2002, 10,283,918 shares of ClearOne common stock were issued and outstanding. Holders of common stock are entitled to one vote per share on all matters voted upon by stockholders. All shares rank equally as to voting and all other matters. The shares of ClearOne common stock have no preemptive or conversion rights, no redemption or sinking fund provisions, are not liable for further call or assessment, and are not entitled to cumulative voting rights. All of the issued and outstanding shares of ClearOne common stock are fully paid and nonassessable. In the event of a liquidation or dissolution of ClearOne, whether voluntary or involuntary, the holders of ClearOne common stock will be entitled to receive, pro rata, the assets of ClearOne remaining for distribution to its stockholders. The holders of ClearOne common stock will be entitled to receive, pro rata, dividends out of legally available funds, but only when, as and if declared by the ClearOne board of directors. See also "Comparison of Stockholder Rights." 45

Listing with Nasdaq the ClearOne Common Stock to be Issued in the Merger ClearOne has agreed to cause the shares of ClearOne common stock to be issued in the merger to be approved for listing on the Nasdaq National Market before the completion of the merger, subject to official notice of issuance. Delisting and Deregistration of E.mergent Common Stock After the Merger When the merger is completed, E.mergent common stock will be delisted from the Nasdaq SmallCap Market and will be deregistered under the Securities Exchange Act. Operations After the Merger Following the merger, E.mergent will continue its operations as a wholly-owned subsidiary of ClearOne for some period of time. The stockholders of E.mergent will become stockholders of ClearOne, and their rights as stockholders will be governed by the ClearOne articles of incorporation, as currently in effect, the ClearOne bylaws and the laws of the State of Utah. See the section entitled "Comparison of Stockholder Rights" beginning on page 67 of this document. The membership of ClearOne's board of directors will remain unchanged as a result of the merger. Further, it is anticipated that upon the closing of the merger, Robin Sheeley, E.mergent's current Chief Technical Officer will become ClearOne's new Chief Technology Officer, Jim Hansen will resign as E.mergent's Chairman, Chief Executive Officer, President and Treasurer and Jill Larson will resign as E.mergent's Vice President-Administration and Corporate Secretary. Exchange of E.mergent Stock Certificates for ClearOne Stock Certificates Promptly after the effective time of the merger, if you are the holder of an E.mergent stock certificate, the exchange agent for the merger, American Stock Transfer, will mail to you a letter of transmittal and instructions for surrendering your E.mergent stock certificates in exchange for the cash payment and ClearOne stock certificates being issued in the merger, and any dividends or other distributions, if any, to which you are or may be entitled. When you deliver your E.mergent stock certificates to the exchange agent, along with any required documents, your E.mergent stock certificates will be canceled and, if you are a holder of E.mergent common stock, you will receive ClearOne stock certificates representing the number of full shares of ClearOne common stock to which you are entitled under the merger agreement and you will receive a check payable in the amount of the aggregate cash consideration, without interest, payable to you in connection with the merger. You will also receive payment in cash, without interest, in lieu of any fractional share of ClearOne common stock that would have been otherwise issuable to you as a result of the merger. YOU SHOULD NOT SUBMIT YOUR E.MERGENT STOCK CERTIFICATES FOR EXCHANGE UNTIL YOU RECEIVE INSTRUCTIONS FROM THE EXCHANGE AGENT FOR THE MERGER. You are not entitled to receive any dividends or other distributions on ClearOne common stock with a record date after the merger is completed until you have surrendered your E.mergent stock certificates. Promptly after your ClearOne stock certificates are issued, you will receive payment for any dividend or other distribution on ClearOne common stock with a record date after the merger and a payment date prior to the date you surrender your E.mergent stock certificates. ClearOne will only make the cash payment and issue a ClearOne stock certificate in a name other than the name in which a surrendered E.mergent stock certificate is registered if you present the exchange agent with all documents required to show and effect the unrecorded transfer of ownership of the shares of E.mergent common stock formerly represented by such E.mergent stock certificate, and show that you paid any applicable stock transfer taxes. If your E.mergent stock certificate has been lost, stolen or destroyed, you may be required to deliver an affidavit and a lost certificate bond as a condition to receiving your cash payment and ClearOne stock certificate. The cash and stock issuable to you in the merger is subject to withholding taxes to the extent required under U.S. federal or state, local or foreign law. 46

AGREEMENT AND PLAN OF MERGER The following summary of the merger agreement is qualified in its entirety by reference to the complete text of the merger agreement, which is attached as Annex A to this proxy statement/prospectus. We urge you to read the full text of the merger agreement. Structure of the Merger Under the terms of the merger agreement, E.mergent will be merged with and into Tundra, and Tundra will survive the merger as a wholly-owned subsidiary of ClearOne. After the merger, the subsidiary will use the name E.mergent, Inc. or such other name as determined by ClearOne. Completion and Effectiveness of the Merger Assuming that all of the conditions to completion of the merger contained in the merger agreement have been satisfied or waived, we expect to complete the merger shortly after approval of the merger by the E.mergent stockholders. As part of completing the merger, ClearOne and E.mergent will file a certificate of merger with the State of Delaware, and the merger will become effective at the time specified in the certificate of merger. Because the merger is subject to certain conditions as described below, however, we are not able to predict the precise timing of the completion of the merger. Conversion of E.mergent Common Stock At the effective time of the merger, by virtue of the merger and without any action on the part of ClearOne, E.mergent or any of their respective security holders, each outstanding share of E.mergent common stock issued and outstanding immediately prior to the effective time will be canceled and extinguished and automatically converted into the right to receive a fixed number of shares of ClearOne common stock and a fixed amount of cash. The number of shares of ClearOne common stock and the amount of cash is based on exchange ratios calculated at the completion of the merger as follows: o each issued and outstanding share of E.mergent common stock will receive an amount of cash determined by dividing (A) $7,300,000 by (B) the total number of shares of E.mergent common stock issued and outstanding immediately prior to the effective time of the merger; and o each issued and outstanding share of E.mergent common stock will receive a fraction of a share of ClearOne common stock determined by the following formula: (A - B) / C where A = 873,000 B = the aggregate number of shares of ClearOne common stock allocated to the E.mergent shares subject to the E.mergent stock options being assumed by ClearOne in the merger C = the number of issued and outstanding shares of E.mergent common stock issued and outstanding immediately prior to the effective time of the merger The number of ClearOne common stock shares allocated to the E.mergent stock options being assumed by ClearOne is determined by multiplying the number of E.mergent stock options outstanding immediately prior to completion of the merger by an option exchange ratio. The option exchange ratio is calculated at completion of the merger as follows: Option exchange ratio = (TV / TS) / AP where TV = the sum of $7,300,000 plus the product of (i) 873,000 times (ii) the weighted average closing price of the ClearOne common stock for the 10 trading days ending one trading day prior to the date of completion of the merger, as quoted on the Nasdaq National Market 47

TS = the aggregate number of shares of E.mergent common stock and E.mergent stock options outstanding immediately prior to the effective time of the merger AP = the weighted average closing price of the ClearOne common stock for the 10 trading days ending one trading day prior to the date of completion of the merger, as quoted on the Nasdaq National Market E.mergent common stock held in the E.mergent Employee Stock Purchase Plan immediately prior to the effective time will be converted at the completion of the merger in the manner applicable to other outstanding E.mergent common stock. Any outstanding employee deposits in the Employee Stock Purchase Plan not applied to the purchase of shares of E.mergent common stock at that time will be refunded to the depositing employee. As described above, the amount of cash and shares of ClearOne common stock that will be exchanged in the merger for each share of E.mergent common stock will depend on a number of factors determined immediately prior to the merger: (1) the number of issued and outstanding shares of E.mergent common stock; (2) the weighted average closing price of ClearOne common stock, (3) the number of E.mergent stock options remaining outstanding after any option exercises completed prior to the merger, (4) whether the exercise of stock options prior to the merger is done with cash or in a cashless manner, and (5) if options are exercised in a cashless manner, the closing price of a share of E.mergent common stock on the date of exercise. The table below shows how the approximate amount of cash and ClearOne common stock shares that would be exchanged for each issued and outstanding share of E.mergent common stock in the merger may vary with changes in the weighted average closing price of the ClearOne common stock and the number of E.mergent stock options that are exercised prior to the merger: E.mergent Stock Options Exercised (Cashless Exercise) -------------------------------------------------------------------------------------------- ClearOne None 50% 100% Average ------------------------------ ----------------------------- ---------------------------- Market ClearOne Combined ClearOne Combined ClearOne Combined Price Cash Shares Value Cash Shares Value Cash Shares Value - ------------ ------------------------------ ----------------------------- ---------------------------- $12.00 $1.231 0.1240 $2.719 $1.198 0.1318 $2.779 $1.167 0.1396 $2.842 $13.00 $1.231 0.1248 $2.853 $1.198 0.1321 $2.916 $1.167 0.1396 $2.981 $14.00 $1.231 0.1254 $2.986 $1.198 0.1324 $3.052 $1.167 0.1396 $3.121 $15.00 $1.231 0.1259 $3.120 $1.198 0.1327 $3.189 $1.167 0.1396 $3.260 $16.00 $1.231 0.1264 $3.253 $1.198 0.1329 $3.325 $1.167 0.1396 $3.400 $17.00 $1.231 0.1268 $3.387 $1.198 0.1331 $3.461 $1.167 0.1396 $3.539 *$17.20 $1.231 0.1269 $3.414 $1.198 0.1331 $3.489 $1.167 0.1396 $3.567 $18.00 $1.231 0.1272 $3.520 $1.198 0.1333 $3.598 $1.167 0.1396 $3.679 $19.00 $1.231 0.1275 $3.654 $1.198 0.1335 $3.734 $1.167 0.1396 $3.819 $20.00 $1.231 0.1278 $3.787 $1.198 0.1336 $3.871 $1.167 0.1396 $3.958 $21.00 $1.231 0.1281 $3.921 $1.198 0.1338 $4.007 $1.167 0.1396 $4.098 $22.00 $1.231 0.1284 $4.055 $1.198 0.1339 $4.144 $1.167 0.1396 $4.237 $23.00 $1.231 0.1286 $4.188 $1.198 0.1340 $4.280 $1.167 0.1396 $4.377 ------------------------------ ----------------------------- ---------------------------- *The actual closing sales price of ClearOne common stock on May 3, 2002. The table is based on the following assumptions: (1) E.mergent has 5,931,280 shares issued and outstanding (which was the number actually issued and outstanding on May 3, 2002, including 50,317 treasury shares E.mergent intends to issue as employee bonuses prior to the merger), (2) E.mergent does not issue additional shares of common stock prior to the merger except pursuant to the exercise of outstanding stock options; and (3) any exercise of the 606,000 outstanding E.mergent stock options is done in a cashless manner using a price of $3.40 per E.mergent share (which was the closing share price of E.mergent common stock on May 3, 2002) to determine the value of the options extinguished in the exercise. While the table above shows the approximate exchange amounts resulting from a weighted average price of ClearOne common stock that is between $23 and $12, such weighted average price could be above or below that range. In such 48

case, the approximate exchange amounts would change based on such price. However, both E.mergent and ClearOne have the right to terminate the merger if the weighted average closing price of ClearOne common stock for the 15 trading days ending one day prior to the date of the scheduled completion of the merger is greater than $23 or less than $14. The examples given above are estimates based upon assumptions that may or may not be accurate at the effective time of the merger. The actual exchange ratios in the merger may differ from these examples. For example, the exercise of E.mergent stock options with cash instead of through cashless exercises, will have the effect of increasing the number of issued and outstanding E.mergent common stock shares at the time of the merger, thereby reducing the amount of cash and shares of ClearOne common stock that would be exchanged for each E.mergent share. Each share of E.mergent common stock held by E.mergent, ClearOne, or any direct or indirect wholly-owned subsidiary of ClearOne immediately prior to the effective time of the merger will be canceled and extinguished. Fifty thousand three hundred and seventeen (50,317) shares of E.mergent common stock currently held by E.mergent as treasury shares will be issued to E.mergent employees as part of an anticipated bonus prior to completion of the merger and will be treated as issued and outstanding shares at the effective time of the merger. The exchange ratios used in the merger will also be adjusted to reflect the effect of any forward stock split, reverse stock split, stock dividend (including any dividend or distribution of securities convertible into ClearOne common stock or E.mergent common stock), extraordinary cash dividend, reorganization, recapitalization, reclassification, combination, exchange of shares or other like changes with respect to ClearOne common stock or E.mergent common stock occurring prior to the effective time of the merger. Fractional Shares No fractional shares of ClearOne common stock will be issued in connection with the merger. In lieu of a fraction of a share of ClearOne common stock each holder of E.mergent common stock who would otherwise be entitled to receive a fraction of a share of ClearOne common stock will receive an amount of cash, without interest, and rounded to the nearest cent, determined by multiplying such fraction by the average closing price of a share of ClearOne common stock for the ten (10) trading days ending one trading day prior to the date of completion of the merger, as reported on the Nasdaq National Market. Stock Options Upon completion of the merger, each outstanding option to purchase E.mergent common stock, whether vested or unvested, will be assumed by ClearOne and become an option to purchase that number of shares of ClearOne common stock equal to the number of shares of E.mergent common stock issuable upon the exercise of such E.mergent stock option, multiplied by the option exchange ratio for the merger, rounded down to the nearest whole number of shares. The per share exercise price of each such E.mergent stock option will be adjusted to an exercise price equal to the per share exercise price of such E.mergent stock option divided by the option exchange ratio for the merger, rounded up to the nearest whole cent. All other terms of each E.mergent stock option will be unchanged by the merger. As of May 3, 2002, options to purchase approximately 606,000 shares of E.mergent common stock were outstanding in the aggregate. ClearOne will file a registration statement on Form S-8 to register the shares of ClearOne common stock issuable upon the exercise of E.mergent stock options assumed by ClearOne within 15 business days after the effective time of the merger. Certificate Exchange Procedures The merger agreement establishes the procedures for the E.mergent stockholders to exchange their stock certificates in the merger, which procedures are described on page 46 of this proxy statement/prospectus. E.mergent's Representations and Warranties E.mergent made a number of customary representations and warranties to ClearOne in the merger agreement regarding aspects of its business, financial condition, structure and other facts pertinent to the merger.

You are urged to carefully read Articles II and III of the merger agreement entitled "Representations and Warranties of Company" and "Representations and Warranties of Parent and Merger Sub," respectively. E.mergent's Conduct of Business Before Completion of the Merger Under the terms of the merger agreement, E.mergent agreed that, until the earlier of the completion of the merger or termination of the merger agreement, or unless ClearOne consents in writing, E.mergent will: o carry on its business in the usual, regular and ordinary course, in substantially the same manner as it was conducted prior to the date of the merger agreement and in compliance with all applicable laws; o pay its debts and taxes when due; and o pay or perform other material obligations when due; and use its commercially reasonable efforts consistent with past practices and policies to: o preserve intact its present business organization; o keep available the services of its present officers and employees; and o preserve its relationships with customers, suppliers, distributors, licensors, licensees and others with which it has significant business dealings.

You are urged to carefully read Article IV of the merger agreement entitled "Interim Conduct." ClearOne's Conduct of Business Before Completion of the Merger Under the terms of the merger agreement, ClearOne agreed that, until the earlier of the completion of the merger or termination of the merger agreement, or unless E.mergent consents in writing, ClearOne will not declare, set aside or pay any dividends or other distributions unless the consideration given in the merger is appropriately adjusted. Material Covenants Recommendation by E.mergent Board of Directors Under the terms of the merger agreement, E.mergent has agreed that, subject to the merger agreement's provisions regarding withdrawal of the E.mergent board of directors' recommendation regarding the merger: o its board of directors will recommend by unanimous vote of its non-interested directors that its stockholders vote in favor of and adopt and approve the merger agreement and the merger at the E.mergent special stockholders' meeting; o this document will include a statement to the effect that the E.mergent board of directors so unanimously recommends such stockholder approval; and 52

o neither E.mergent nor its board of directors will withdraw, amend or modify, or propose or resolve to withdraw, amend or modify in a manner adverse to ClearOne such unanimous recommendation. For purposes of the merger agreement, the recommendation of the E.mergent board of directors is deemed to have been modified in a manner adverse to ClearOne if it is no longer a unanimous recommendation of its non-interested directors. Solicitations by E.mergent; Withdrawal of Recommendation by E.mergent Board of Directors Under the terms of the merger agreement, E.mergent agreed to cease, as of the date of the merger agreement, any and all existing activities, discussions or negotiations with any parties other than ClearOne conducted prior to the date of the merger agreement with respect to any Acquisition Proposal. Under the terms of the merger agreement, an Acquisition Proposal is any offer or proposal relating to an Acquisition Transaction (other than an offer or proposal from ClearOne), and an Acquisition Transaction is any transaction or series of related transactions (other than the merger) involving any of the following: o the acquisition or purchase from E.mergent by any person or group of more than a 15% interest in the total outstanding voting securities of E.mergent or any of its subsidiaries; o any tender offer or exchange offer that if consummated would result in any person or group beneficially owning 15% or more of the total outstanding voting securities of E.mergent or any of its subsidiaries; o any merger, consolidation, business combination or similar transaction involving E.mergent in which the stockholders of E.mergent immediately preceding such transaction hold less than 85% of the equity interests in the surviving or resulting entity of such transaction; o any sale, lease, exchange, transfer, license, acquisition or disposition of more than 15% of the assets of E.mergent; or o any liquidation or dissolution of E.mergent. Until the merger is completed or the merger agreement is terminated, under the terms of the merger agreement E.mergent further agreed that neither it nor any of its subsidiaries will, directly or indirectly (nor will they authorize or permit any of their respective officers, directors, affiliates or employees or any of their investment bankers, attorneys or other advisors or representatives to): o solicit, initiate, encourage or induce the making, submission or announcement of any Acquisition Proposal; o subject to certain limited exceptions applicable upon receipt of a Superior Offer, as described below, participate in any discussions or negotiations regarding, or furnish non-public information with respect to, any Acquisition Proposal; o take any other action to facilitate any inquiries or the making of any proposal that is or may reasonably be expected to lead to any Acquisition Proposal; o subject to certain limited exceptions applicable upon receipt of a Superior Offer, as described below, engage in discussions with any person with respect to any Acquisition Proposal; o subject to certain limited exceptions in the event of a Superior Offer, as described below, approve, endorse or recommend any Acquisition Proposal; or o enter into any letter of intent or similar document or any contract, agreement or commitment contemplating or otherwise relating to any Acquisition Transaction. Any violation of any of the restrictions described in the preceding paragraph by any officer or director of E.mergent, or any investment banker, attorney or other advisor or representative of E.mergent is deemed to be a breach of the relevant restriction by E.mergent. 53

Under the terms of the merger agreement, E.mergent has also agreed to inform ClearOne, as promptly as practicable, of any request received by E.mergent for non-public information that E.mergent reasonably believes would lead to an Acquisition Proposal, or of any Acquisition Proposal, or any inquiry received by E.mergent with respect to or which E.mergent reasonably should believe would lead to any Acquisition Proposal, the material terms and conditions of such request, Acquisition Proposal or inquiry, and the identity of the person or group making any such request, Acquisition Proposal or inquiry. E.mergent further agreed to use reasonable efforts to keep ClearOne informed in all material respects of the status and details, including material amendments or proposed amendments, of any such request, Acquisition Proposal or inquiry. E.mergent is expressly permitted, however, to furnish non-public information regarding E.mergent and its subsidiaries to, and to enter into a confidentiality agreement with or discussions with, any person or group in response to a Superior Offer submitted by the person or group, and not withdrawn, if all of the following conditions are met: o neither E.mergent nor any of its representatives, or subsidiaries has breached the non-solicitation provisions contained in the merger agreement described above; o the board of directors of E.mergent concludes in good faith, after consultation with its outside legal counsel, that such action is required in order for the E.mergent board of directors to comply with its fiduciary duties to E.mergent's stockholders under applicable law; o at least three business days prior to furnishing any such information to, or entering into discussions or negotiations with, the person or group, E.mergent gives ClearOne written notice of the identity of such person or group and of E.mergent's intention to furnish information to, or enter into discussion or negotiations with, such person or group, and E.mergent receives from such person or group an executed confidentiality agreement containing customary limitations on the use and disclosure of all non-public written and oral information furnished to such person or group by or on behalf of E.mergent; and o contemporaneously with furnishing any non-public information to the person or group, E.mergent furnishes the same non-public information to ClearOne, to the extent such non-public information has not been previously furnished by E.mergent to ClearOne. Under the terms of the merger agreement, a Superior Offer is an unsolicited, bona fide, written offer from a third party to consummate any of the following transactions on terms that the board of directors of E.mergent determines, in its reasonable judgment, based on the advice of a financial advisor of nationally recognized reputation, to be more favorable to the E.mergent stockholders from a financial point of view than the terms of the merger: o a merger, consolidation, business combination, recapitalization, liquidation, dissolution or similar transaction involving E.mergent pursuant to which the stockholders of E.mergent immediately preceding such transaction hold less than a majority of the equity interests in the surviving or resulting entity of such transaction; o the acquisition by any person or group, including by way of a tender or exchange offer or issuance by E.mergent, directly or indirectly, of beneficial ownership or a right to acquire beneficial ownership of shares representing a majority of the voting power of the outstanding shares of E.mergent's capital stock; or o a sale or other disposition by E.mergent of substantially all of its assets. Under the terms of the merger agreement, the E.mergent board of directors is permitted to withdraw, amend or modify the unanimous recommendation of its non-interested directors in favor of the merger only if: o a Superior Offer is made and not withdrawn; o neither E.mergent nor any of its representatives has breached the non-solicitation provisions of the merger agreement described above; and o the board of directors of E.mergent concludes in good faith, after consultation with its outside counsel that, in light of the Superior Offer, the withdrawal, amendment or modification of its 54

recommendation is required in order for the E.mergent board of directors to comply with its fiduciary duties to E.mergent's stockholders under applicable law. E.mergent must give ClearOne at least 72 hours notice of the commencement of the change to the unanimous recommendation of its non-interested directors, and provide ClearOne with the opportunity to meet with E.mergent and its counsel. In addition, under the terms of the merger agreement, E.mergent has agreed to provide ClearOne with at least 48 hours prior notice (or such lesser prior notice as provided to the E.mergent board of directors, but in no event less than eight hours) of any meeting of the E.mergent board of directors at which the E.mergent board of directors is reasonably expected to consider a Superior Offer. Furthermore, E.mergent has agreed to provide ClearOne with at least three business days prior written notice of a meeting of the E.mergent board of directors at which the E.mergent board of directors is reasonably expected to recommend a Superior Offer to E.mergent's stockholders (together with a copy of the all documentation relating to such Superior Offer). Regardless of whether there has been a Superior Offer, and regardless of whether the E.mergent board of directors withdraws, amends or modifies the unanimous recommendation of its non-interested directors in favor of the merger, E.mergent is obligated, under the terms of the merger agreement, to hold and convene the special meeting of E.mergent stockholders at which the merger agreement and the merger will be considered and voted upon. Other Covenants Under the terms of the merger agreement, each of ClearOne and E.mergent have also agreed to the following additional items: o E.mergent has agreed to take the necessary action to hold the special shareholders meeting for the purposes of obtaining stockholder approval of the merger agreement and the merger, all in compliance with applicable law and Nasdaq requirements. o E.mergent has agreed to use its commercially reasonable efforts to solicit from its stockholders proxies in favor of the adoption and approval of the merger agreement and the approval of the merger and shall take all other action necessary or advisable to secure the vote or consent of its stockholders required by the rules of Nasdaq and applicable law. o Both ClearOne and E.mergent will take the necessary action to prepare this proxy statement/prospectus and related registration statement, and cooperate with each other to take such other action and file other documents as are necessary to comply with applicable securities laws. o E.mergent will allow ClearOne and its agents access to E.mergent's properties, books, records and personnel for the purpose of obtaining information about E.mergent and its properties. o ClearOne will provide E.mergent employees who remain after the merger with employment benefits that are substantially comparable in the aggregate to benefits available to similarly situated employees of ClearOne and its subsidiaries, provided such benefits are available on reasonably acceptable terms. Unless requested otherwise by ClearOne, E.mergent's 401k plan will be terminated. ClearOne will take steps, to the extent practicable and permitted by ClearOne's plan, to enable continuing employees to roll over distributions to a tax-qualified defined contribution plan maintained by ClearOne or an affiliate of ClearOne. o Each of ClearOne and E.mergent will use its commercially reasonable efforts to take, or cause to be taken, all reasonable actions and to do, or cause to be done, all things necessary, proper or advisable to consummate and make effective in the most expeditious manner practicable the merger and transactions contemplated by the merger agreement and to assist and cooperate with each other in doing such things, including: o causing the conditions to the completion of the merger to be satisfied; o obtaining any necessary actions, waivers, consents, approvals, orders and authorizations by or from any governmental entity, making all necessary registrations, declarations and filings, avoiding any suit, claim, action, investigation or proceeding by any governmental entity; 55

o defending all lawsuits or other legal proceedings challenging the merger agreement or the consummation of the merger; and o executing or delivering any additional instruments reasonably necessary to consummate the transactions contemplated by the merger agreement. o Each of ClearOne and E.mergent will use its commercially reasonable efforts to obtain any consents, waivers and approvals under any of its or its subsidiaries' respective agreements, contracts, licenses or leases required to be obtained from third parties in connection with the consummation of the transactions contemplated by the merger agreement. o Each of ClearOne and E.mergent will promptly notify the other upon becoming aware of any breach in any material respect of any representation or warranty contained in, or failure to comply in any material respect with any covenant, condition or agreement to be complied with or satisfied by it under, the merger agreement. o ClearOne will take such action as is necessary to ensure that the shares of ClearOne common stock issuable in connection with the merger will be listed on the Nasdaq National Market. o ClearOne and E.mergent will consult with each other, and agree, before issuing any press release, and will consult with each other and to the extent practicable, agree, before otherwise making any public statement with respect to the merger agreement, the other party, or an Acquisition Proposal. o ClearOne will file a registration statement on Form S-8 to register the shares of ClearOne common stock issuable upon the exercise of E.mergent stock options assumed by ClearOne within 15 business days after the effective time of the merger. The agreements related to the conduct of E.mergent and ClearOne prior to the closing of the merger are complicated and not easily summarized. You are urged to carefully read Article V of the merger agreement entitled "Additional Agreements." Conditions to Completion of the Merger The obligations of ClearOne and E.mergent to complete the merger and the other transactions contemplated by the merger agreement are subject to the satisfaction or waiver, where permitted, of each of the following conditions: o the merger agreement must have been adopted and approved, and the merger must have been approved, by the requisite stockholders of E.mergent; o no court or other governmental entity have enacted or issued any statute, rule, regulation, judgment, decree, injunction or other order which prohibits consummation of the merger; o ClearOne's registration statement on Form S-4 of which this document forms a part must have been declared effective, no stop order suspending its effectiveness may be in effect and no proceedings for suspension of its effectiveness may be pending before or threatened in writing by the Securities and Exchange Commission; and o the shares of ClearOne common stock to be issued in the merger must have been authorized for listing on the Nasdaq National Market. E.mergent's obligations to complete the merger and the other transactions contemplated by the merger agreement are subject to the satisfaction or waiver of each of the following additional conditions: o each of ClearOne's and Tundra's representations and warranties must have been true and correct as of the date of the merger agreement, and must continue to be true and correct on and as of the date the merger is to be completed as if made on such date, except: o to the extent ClearOne's and Tundra's representations and warranties address matters only as of a particular date, they must be true correct only as of that date; 56

o to the extent that any inaccuracies of such representations and breaches of such warranties do not in any case, or in the aggregate, have a material adverse effect on ClearOne and Tundra; or o for changes contemplated by the merger agreement; and o ClearOne and Tundra must have performed or complied in all material respects with all of their agreements and covenants required by the merger agreement to be performed or complied with by ClearOne and Tundra. ClearOne's obligations to complete the merger and the other transactions contemplated by the merger agreement are subject to the satisfaction or waiver of each of the following additional conditions: o each of E.mergent's representations and warranties must have been true and correct as of the date of the merger agreement, and must continue to be true and correct on and as of the date the merger is to be completed as if made on such date, except: o to the extent E.mergent's representations and warranties address matters only as of a particular date, they must be true and correct only as of that date; o to the extent that any inaccuracies of such representations and breaches of such warranties do not in any case, or in the aggregate, have a material adverse effect on E.mergent (except with regard to capitalization); or o for changes contemplated by the merger agreement; and o E.mergent must have performed or complied in all material respects with all of its agreements and covenants required by the merger agreement to be performed or complied with by E.mergent; o E.mergent shall have obtained all consents, waivers and approvals required by specific contracts identified in the merger agreement; o each of the affiliate agreements contemplated by the merger agreement, as described below, must have been delivered and must be in full force and effect; and o the audited financial statements of E.mergent for the year ended December 31, 2001, shall provide (i) balance sheet net equity of not less than $7,267,500, (ii) year end revenues of not less than $21,280,000 and (iii) net income of not less than $498,750 (excluding transaction related expenses estimated to be $85,000, and any excess tax liability over forty percent (40%) that has been applied to the calculation of net income by E.mergent for the year ending December 31, 2001). This last condition has been met by E.mergent. In the event that either E.mergent or ClearOne elect to waive a condition to closing that it's board of directors considers material, they intend to resolicit shareholder approval of the merger following appropriate disclosure of such waiver. Termination of the Merger Agreement The merger agreement may be terminated in accordance with its terms at any time prior to completion of the merger, whether before or after the adoption and approval of the merger agreement and approval of the merger by E.mergent's stockholders: o by mutual written consent duly authorized by the boards of directors of ClearOne and E.mergent; o by ClearOne or E.mergent, if the merger is not completed before May 31, 2002, except that either party's right to terminate the merger agreement under this provision will not be available to any party whose action or failure to act has been a principal cause of or resulted in the failure of the merger to occur on or before such dates, and such action or failure to act constitutes a breach of the merger agreement; o by ClearOne or E.mergent, if E.mergent's stockholders fail to adopt and approve the merger agreement and approve the merger at the E.mergent special meeting or at any adjournment or postponement of 57

that meeting, except that E.mergent's right to terminate the merger agreement under this provision is not available to E.mergent where the failure to obtain stockholder approval was caused by E.mergent's action or failure to act which constitutes a breach by E.mergent of the merger agreement; o by ClearOne or E.mergent, if any governmental authority has issued an order, or taken any other action, having the effect of making the merger illegal or permanently restraining, enjoining or otherwise prohibiting the merger and which is final and nonappealable; o by E.mergent, upon a material breach of any covenant or agreement on the part of ClearOne in the merger agreement, or if any of ClearOne's representations or warranties are or become untrue such that the condition to E.mergent's obligation to complete the merger relating to the continued accuracy of ClearOne's representations and warranties would not be satisfied. However, if the breach or inaccuracy is curable by ClearOne through the exercise of its commercially reasonable efforts, and ClearOne continues to exercise such commercially reasonable efforts, E.mergent may not terminate the merger agreement for 30 days after delivery of written notice to ClearOne of the breach. If the breach or inaccuracy is cured during those 30 days, E.mergent may not terminate the merger agreement under this provision; o by ClearOne, upon a material breach of any covenant or agreement on the part of E.mergent set forth in the merger agreement, or if any of E.mergent's representations or warranties are or become untrue such that the condition to ClearOne's obligation to complete the merger relating to the continued accuracy of E.mergent's representations and warranties would not be satisfied. However, if the breach or inaccuracy is curable by E.mergent through the exercise of its commercially reasonable efforts, and E.mergent continues to exercise such commercially reasonable efforts, ClearOne may not terminate the merger agreement for 30 days after delivery of written notice to E.mergent of the breach. If the breach or inaccuracy is cured during those 30 days, ClearOne may not terminate the merger agreement under this provision; o by ClearOne, if an event has occurred or a circumstance has arisen that would reasonably be expected to have a material adverse effect on E.mergent that is not curable by E.mergent through the exercise of its commercially reasonable efforts within sixty (60) days of the date of such occurrence or circumstance; o by E.mergent, if an event has occurred or a circumstance has arisen that would reasonably be expected to have a material adverse effect on ClearOne that is not curable by ClearOne through the exercise of its commercially reasonable efforts within sixty (60) days of the date of such occurrence or circumstance; o by ClearOne, if a Triggering Event shall have occurred; o by ClearOne, in the event that E.mergent stockholders holding 15% or more of the issued and outstanding shares of the E.mergent elect to pursue dissenters rights, whether such holders have perfected such rights or not; or o by ClearOne or E.mergent in the event that the weighted average closing price of ClearOne common stock as quoted on the Nasdaq National Market for the fifteen (15) trading days ending one day prior to the date of the scheduled completion of the merger is greater than $23 or less than $14. Under the terms of the merger agreement, a Triggering Event is deemed to have occurred if: o E.mergent's board of directors withdraws, amends or modifies in a manner adverse to ClearOne, the unanimous recommendation of its non-interested directors in favor of the adoption and approval of the merger agreement or the approval of the merger; o E.mergent fails to include in this document such unanimous recommendation of E.mergent's board of directors in favor of the adoption and approval of the merger agreement and the approval of the merger; o E.mergent's board of directors approves or recommends any Acquisition Proposal; 58

o E.mergent enters into any letter of intent or similar agreement, contract or commitment accepting any Acquisition Proposal; or o a tender or exchange offer relating to the securities of E.mergent is commenced by a person unaffiliated with ClearOne, and E.mergent does not send to its stockholders within 10 business days after such tender or exchange offer is first published, sent or given, a statement disclosing that E.mergent recommends rejection of such tender or exchange offer. E.mergent may also terminate the merger agreement if it intends to enter into a definitive agreement with respect to an Acquisition Proposal, provided that: o E.mergent is not in breach of its obligations under the merger agreement with respect to such Acquisition Proposals; and continues to comply with all such obligations in all respects; o E.mergent's board of directors has authorized, subject to complying with the terms of the merger agreement, E.mergent to enter into a definitive written agreement for a transaction that constitutes a Superior Proposal; o E.mergent notified ClearOne in writing that E.mergent has received a Superior Proposal and intends to enter into a definitive agreement with respect to such Superior Proposal, attaching the most current version of such agreement to such notice; o ClearOne does not make, within three business days after receipt of E.mergent's written notice of its intention to enter into a definitive agreement for a Superior Proposal, an offer that E.mergent's board of directors in good faith reasonably determines, after consultation with a financial advisor of nationally recognized standing and its outside legal counsel, is at least as favorable to E.mergent's stockholders as such Superior Proposal; o during such period, E.mergent has informed ClearOne of the terms and conditions of such Superior Proposal, and the identity of the person making such Superior Proposal, with the intent of enabling both parties to agree to a modification of the terms and conditions of the merger agreement so that the transactions contemplated under the merger agreement may be effected; and o prior to E.mergent's termination under the above provisions, E.mergent pays to ClearOne the Termination Fee described below. Payment of the Termination Fee Under the terms of the merger agreement, E.mergent must pay ClearOne a termination fee of $1,000,000 plus up to $500,000 of ClearOne's actual legal, advisory and accounting fees incurred in connection with the merger, within one business day after termination, if the merger agreement is terminated: o by ClearOne upon the occurrence of a Triggering Event; or o by E.mergent if it determined to enter into a definitive agreement with respect to an Acquisition Proposal in accordance with the termination provisions described above. Alternatively, if ClearOne terminates the merger agreement for a material breach of any covenant or agreement on the part of E.mergent, or if any of E.mergent's representations or warranties are or become untrue such that the condition to ClearOne's obligation to complete the merger relating to the continued accuracy of E.mergent's representations and warranties would not be satisfied (subject to the applicable cure period), then E.mergent must pay up to $500,000 of ClearOne's actual legal, advisory and accounting fees incurred in connection with the merger. In addition, if E.mergent terminates the merger agreement for a material breach of any covenant or agreement on the part of ClearOne, or if any of ClearOne's representations or warranties are or become untrue such that the condition to E.mergent's obligation to complete the merger relating to the continued accuracy of ClearOne's representations and warranties would not be satisfied (subject to the applicable cure period), then ClearOne must pay up to $500,000 of E.mergent's actual legal, advisory and accounting fees incurred in connection with the merger. 59

Effect of Termination Upon termination of the merger agreement, it will be of no further force or effect without liability of any party to the other parties, except for: o payment of the termination fee as described above; o liability for any intentional or willful breach of or fraud in connection with the merger agreement; and o the miscellaneous provisions of the merger agreement. Except for the termination fee described above and cost associated with the collection of such fee, each party will pay all fees and expenses it incurs in the merger. Extension, Waiver and Amendment of the Merger Agreement ClearOne and E.mergent may amend the merger agreement before completion of the merger by mutual written consent. Either ClearOne or E.mergent may extend the other party's time for the performance of any of the obligations or other acts under the merger agreement, waive any inaccuracies in the other's representations and warranties and waive compliance by the other party with any of the agreements or conditions contained in the merger agreement. Definition of Material Adverse Effect Under the terms of the merger agreement, a "material adverse effect" on either ClearOne or E.mergent is defined to mean any change or effect in the business of such company that, individually or when taken together with all other such changes or effects that have occurred prior to the date of determination, is or is reasonably likely to be materially adverse to the business, assets, financial condition or results of operations of such entity and its subsidiaries, taken as a whole. However, none of the following, alone or in combination, will be deemed to constitute, or taken into account in determining whether there has been or will be, a material adverse effect on any entity: o any change or effect that results or arises from changes affecting any of the industries in which such entity operates generally or the United States economy generally (which changes or effects in each case do not materially disproportionately affect such entity); or o any change or effect that results or arises from changes affecting general worldwide economic or capital market conditions (which changes in each case do not materially disproportionately affect such entity). Amendment of Merger Agreement On March 29, 2002, ClearOne and E.mergent amended the merger agreement to extend, from May 7, 2002 to May 31, 2002, the date after which the merger agreement could be terminated by either party if the merger had yet to be completed (see Annex A-1). 60

ANCILLARY AGREEMENTS Voting Agreement In connection with the execution of the merger agreement, three directors and one officer of E.mergent who together hold approximately 40% of the voting power of E.mergent's voting shares, each executed voting agreements with ClearOne dated as of the date of the merger agreement. The directors and officer are James Hansen, Robin Sheeley, Richard Craven and Jill Larson. In the voting agreements, these E.mergent stockholders agreed to: o vote the stockholder's shares and exercise all consent and similar rights in favor of the approval and adoption of the merger, the merger agreement, each other transaction contemplated by the merger agreement and in favor of any action required in furtherance of the consummation of the merger; o vote against any proposal made in opposition to, or in competition with, consummation of the merger and the transactions contemplated by the merger agreement; o grant, and did grant, to ClearOne irrevocable proxies to vote their shares as required by the voting agreement; and o upon request of ClearOne, execute and deliver any additional documents and take such further actions as may reasonably be deemed by ClearOne to be necessary or desirable to carry out the provisions of the voting agreement and to vest in ClearOne the power to vote stockholder's shares as contemplated by the voting agreement. Furthermore, each of these stockholders agreed not to: o sell, transfer, pledge, encumber, grant an option with respect to or otherwise dispose any interest in the stockholders shares of voting securities of E.mergent, including E.mergent stock options, unless the transferee of the voting securities agrees to be bound by the terms of the voting agreement and delivers a proxy to ClearOne; o enter into any agreement or commitment, with respect to the sale, transfer, pledge, encumbrance, grant of an option with respect to or other disposition of any of the voting securities of E.mergent unless the transferee of the voting securities agrees to be bound by the terms of the voting agreement and delivers a proxy to ClearOne; o deposit its shares of voting securities of E.mergent into a voting trust or grant any proxy or enter into a voting agreement or other arrangement with respect to such shares in contravention of the voting agreement; or o exercise dissenter's rights. Further, under the voting agreement, no stockholder subject to the agreement will, nor will any stockholder authorize or permit any of such stockholder's affiliates or any investment banker, attorney or other advisor or representative retained by any of them to, directly or indirectly: o solicit, initiate, encourage or induce the making, submission or announcement of any Acquisition Proposal; o participate in any discussions or negotiations regarding, or furnish to any person any information with respect to, or take any other action to facilitate any inquiries or the making of any proposal that constitutes or may reasonably be expected to lead to, any Acquisition Proposal; o engage in discussions with any person with respect to any Acquisition Proposal; o approve, endorse or recommend any Acquisition Proposal; or o enter into any letter of intent or similar document or any contract, agreement or commitment contemplating or otherwise relating to any Acquisition Transaction. 61

However, nothing in the voting agreement prohibits such a stockholder from taking action in the stockholder's capacity as a director or officer of E.mergent to the extent otherwise permitted by the merger agreement. The voting agreement terminates upon the earliest to occur of: o the closing of the transactions contemplated by the merger agreement; and o the date the merger agreement is terminated in accordance with its terms. The form of voting agreement is attached to this document as Annex B, and you are urged to read it in its entirety. Affiliate Agreements As a condition to ClearOne's entering into the merger agreement, each member of the E.mergent board of directors of E.mergent are required to enter into affiliate agreements with ClearOne. Under the terms of the affiliate agreements, ClearOne will be entitled to place appropriate legends on the certificates evidencing any ClearOne common stock to be received by these persons and to issue stop transfer instructions to the transfer agent for the ClearOne common stock. Additionally, these persons have acknowledged the resale restrictions imposed by Rule 145 under the Securities Act on shares of ClearOne common stock to be received by them in the merger. 62

INFORMATION ABOUT CLEARONE For information about ClearOne, see "Where You Can Find More Information" on page 72 of this proxy statement/prospectus. In addition, certain recent ClearOne events and changes in ClearOne's operations are described below. Amendment of Agreement Regarding Acquisition of Ivron Systems On April 8, 2002, ClearOne entered into an amendment to the original Share Purchase Agreement between ClearOne and the shareholders of Ivron Systems, Ltd. Under the original agreement, on October 3, 2001, ClearOne, through its wholly owned subsidiary, Gentner Ventures, Inc., purchased all of the issued and outstanding shares of Ivron Systems. Under the original Share Purchase Agreement, the shareholders of Ivron received approximately US$6,000,000 at closing of the purchase. Further, under that agreement, after June 30, 2002, each former Ivron shareholder would be entitled to receive approximately .08 shares of ClearOne's common shares for each Ivron share previously held by such shareholder, provided that certain video product development contingencies were achieved. That represented approximately 429,000 shares of ClearOne's common stock. Thereafter, for ClearOne's completed fiscal years 2003 and 2004, the former Ivron shareholders would be entitled to share in up to approximately US$17,000,000 of additional cash and stock consideration provided that certain agreed upon earnings per share targets for ClearOne were achieved. As part of the purchase, all outstanding options to purchase Ivron shares were cancelled in consideration for an aggregate cash payment of US$650,000, allocated among the optionees on the basis of the number of options originally held by each such optionee. In addition, former optionees of Ivron who remain with Ivron are eligible to participate in a cash bonus program paid by Ivron, but based on the combined performance of ClearOne and Ivron in fiscal years 2003 and 2004. The maximum amount payable under this bonus program is up to approximately US$1,000,000. On March 26, 2002, ClearOne entered into negotiations with the former shareholders of Ivron Systems to modify the terms of the original purchase agreement because, upon further analysis, certain aspects of the technology acquired from Ivron may not meet the intended product objectives established by ClearOne in its original purchase negotiations. Originally, ClearOne expected to develop a full line of videoconferencing products, including an installed video codec product, based on the Ivron Systems V-There technology platform. Given the results of its analysis, ClearOne has now identified an opportunity to collaborate in the development of a video codec, based on other readily-available technology, specifically designed for the high-end, installed videoconferencing market, that combines faster frames-per-second, built-in multipoint conferencing, and ClearOne's high-quality audio. The negotiations were based on the results of an analysis by ClearOne that although the Ivron platform is well-suited for the lower- to mid-priced videoconferencing products, it is not as well-suited for an installed video codec product. These negotiations resulted in an amendment to the original October 3, 2001 purchase agreement. The amendment eliminates the earn-out that the Ivron shareholders would have been entitled to receive after June 30, 2002 for approximately 429,000 shares and the $17 million earn-out in subsequent years. Instead, upon meeting certain gross profit targets for ClearOne's "V-There", "Vu-Link" set top videoconferencing products, technologies, and variants and sub-elements thereof (including licensed products), the former Ivron Shareholders may share in an earn-out of up to 109,000 shares of common stock of ClearOne, issuable in four installments, on a quarterly basis, through July 15, 2003. Therefore, with the amendment, the total purchase price will now include the original $6.7 million in cash paid in October of 2001, the revised earn-out of up to 109,000 shares, and the original bonus to be paid in 2003 and 2004 of up to $1 million for the former option holders of Ivron, the last two of which are dependent upon the achievement of certain targets. ClearOne currently anticipates that the Dublin, Ireland operations acquired in the Ivron transaction will continue, although it is expected that existing research and development efforts and personnel there will be reduced to focus primarily on the development and enhancement of the V-There products and not on the installed video codec element. Management Following the closing of the purchase of Ivron Systems, Michael Peirce, the former chairman of Ivron, was appointed to ClearOne's board of directors. Since September 30, 2001, the following new ClearOne officers have been appointed: DeLonnie Call - Vice President - Human Resources; Angelina Beitia - Vice President - Marketing; Kevin Davis - Vice President - Conferencing Services; Gene Kuntz - Chief Operating Officer; and Andrew S. Fellows, Vice President of Services. Mr. Kuntz subsequently resigned effective May 1, 2002. 64

In August 2001, ClearOne granted its CEO, Frances Flood, options to purchase 100,000 shares of common stock. The options have an exercise price of $11.39, expire on August 6, 2010, and are subject to vesting as provided under the ClearOne 1998 Stock Option Plan. Marketing On October 23, 2001, ClearOne announced the implementation a new and major marketing and advertising campaign. This campaign focuses on ClearOne being a provider of an integrated suite of audio and videoconferencing products and services. ClearOne intends to build product demand through its current distribution channel and increase end-user awareness of the Gentner(R) brand. ClearOne anticipates that these marketing efforts will include a new advertising campaign, website, traditional and electronic direct marketing efforts, dealer road shows and training programs, and collateral materials that support channel partner efforts. Recent Financial Developments On April 23, 2002, ClearOne issued a press release reporting its financial results for the three and nine months ended March 31, 2002. Set forth below is certain financial information reported by ClearOne in the press release and filed on Form 8-K on April 23, 2002, which is incorporated by reference. ClearOne Communications Inc.

COMPARISON OF STOCKHOLDER RIGHTS ClearOne is incorporated in the state of Utah under the Utah Revised Business Corporation Act ("URBCA"), and E.mergent is incorporated in the state of Delaware under the Delaware General Corporation Law ("DGCL"). E.mergent's stockholders will, upon consummation of the merger, become stockholders of ClearOne and their rights will be governed by the ClearOne Articles of Incorporation, as amended (the "ClearOne Articles"), the ClearOne By-laws and the URBCA. Certain material differences between the rights of stockholders of ClearOne and stockholders of E.mergent are set forth below. This summary is not intended to be relied upon as an exhaustive list or detailed description of the provisions discussed and is qualified entirely by the URBCA, the DGCL, the ClearOne Articles, the ClearOne By-laws, the E.mergent Certificate of Incorporation ("E.mergent Certificate") and the E.mergent bylaws. Authorized Shares of Capital Stock The authorized capital stock of ClearOne consists of 50,000,000 shares of common stock, $0.001 par value. As of May 3, 2002, 10,283,918 shares of common stock of ClearOne were issued and outstanding. The E.mergent Certificate authorizes the issuance of (i) 20,000,000 shares of common stock, par value $.01 per share, and (ii) 5,000,000 shares of preferred stock, $.01 par value per share, none of which have been issued. As of May 3, 2002, there were outstanding (a) 5,931,280 shares of E.mergent common stock, and (b) employee options to purchase an aggregate of 606,000 shares of common stock. The E.mergent Certificate provides that the board of directors is authorized to provide for the issuance of shares of undesignated preferred stock in one or more series, and to fix the designations, power, preferences and rights of the shares of each series and any related qualifications, limitations or restrictions. Directors Number The ClearOne bylaws provide that the number of directors shall consist of not less than three nor more than nine directors, with the number of directors currently being fixed at seven. Under the ClearOne bylaws the number of directors is required to be fixed by resolution by either the board of directors of ClearOne or the stockholders. The E.mergent bylaws provide that the board of directors of E.mergent will consist of at least one director, with the number of directors currently being fixed at five. In the absence of a resolution of the E.mergent stockholders or the board of directors of E.mergent, the number shall be the number last fixed by the E.mergent's stockholders or the board of directors of E.mergent, provided however, that the board of directors of E.mergent may not decrease the number of directors below the number last designated by the stockholders. Special Meetings Under the ClearOne bylaws, special meetings of ClearOne's board of directors may be called by the chairman of the board or the president on at least two days' notice to each director either by mail, telephone, electronic transmission or facsimile. Under the E.mergent bylaws, special meetings of E.mergent's board of directors may be called by the chairman of the board, the president or by the secretary on three business days' notice to each director if by mail or twenty-four (24) hours notice to each director if delivered personally or by telephone, telegram or facsimile. Removal Any ClearOne director, or the entire board of directors, may be removed from office for cause or without cause by a vote of the ClearOne stockholders provided that the number of the votes cast by the stockholders to remove the director exceeds the number of votes cast not to remove the director. 67

Any E.mergent director, or the entire board of directors, may be removed from office for cause or without cause by the vote of a majority of the shares of E.mergent common stock entitled to vote at the election of the director or board of directors. Election The ClearOne bylaws provide that directors shall be elected at each annual meeting of stockholders by a plurality of the votes present in person or represented by proxy at the meeting and entitled to vote for the election of directors. The E.mergent bylaws provide that directors are elected by a majority of the stockholders voting at a duly held meeting in person or by proxy. Stockholder Action by Written Consent Under the ClearOne bylaws and the URBCA, stockholders may take action without a meeting if a written consent is signed by the holders of outstanding shares of capital stock having the requisite number of votes that would be necessary to authorize or take such action at a meeting of stockholders, and notice of such action is given to all non-consenting stockholders at least 10 days prior to the effectiveness of such action. However, directors may be elected by written consent only if signed by the holders of all outstanding shares of capital stock. Under the E.mergent bylaws and the DGCL, stockholders may take action without a meeting, including election of directors and without prior notice, if a written consent is signed by the holders of outstanding shares of capital stock having the requisite number of votes that would be necessary to authorize or take such action at a meeting of stockholders. Notice of such action must be given promptly to all non-consenting stockholders. Ability to Call Special Meetings of Stockholders Under the ClearOne bylaws and the URBCA, special meetings of the stockholders may be called by either the president or the chairman of the board of directors and must be called by the president at the request of the holders of not less than one-tenth of all the outstanding shares entitled to vote at the meeting. Under the E.mergent bylaws and the DGCL, special meetings of the stockholders may be called by either the president or the board of directors. Stockholders generally do not have the right to call meetings of stockholders unless such right is granted in the certificate of incorporation or bylaws. However, if a corporation fails to hold its annual meeting within a period of 30 days after the date designated therefore, or if no date has been designated for a period of 13 months after its last annual meeting, the Delaware Court of Chancery may order a meeting to be held upon the application of a stockholder. Amendments To Charter Under the ClearOne bylaws and the URBCA, the board of directors may propose amendments to the for submission to the stockholders. For an amendment to be adopted, (i) the board of directors must recommend the amendment to the stockholders (unless the board determines that because of a conflict of interest or other special circumstances it should not make a recommendation and communicates the basis for its determination to the stockholders) and (ii) unless the ClearOne Articles, the ClearOne bylaws (if authorized by the ClearOne Articles), or a resolution of the board of directors require a greater number, the amendment must be approved by (a) a majority of the votes entitled to be cast on the amendment by any voting group as to which the amendment would create dissenters' rights, (b) a majority of the votes entitled to be cast on the amendment by any voting group as to which the amendment would materially and adversely affect the voting group's rights in shares (including preferential rights, rights in redemption, preemptive rights, voting rights or rights in certain reverse splits) and (c) a majority of the votes cast for all other voting groups (voting separately, as applicable). The E.mergent Certificate reserves E.mergent's right to amend, alter, change or repeal any provision contained in the certificate, in the manner prescribed by Delaware law. Under Delaware law, a certificate of incorporation of a Delaware corporation may be amended by approval of the board of directors of the corporation and the affirmative vote of the holders of a majority of the outstanding shares entitled to vote for the amendment, unless a higher vote is required by the corporation's certificate of incorporation. 68

Amendments To By-laws Under the ClearOne bylaws and the URBCA, the board of directors may amend the ClearOne bylaws at any time, except to the extent that the URBCA reserves such power exclusively to a corporation's stockholders. The URBCA provides that stockholders may amend a corporation's bylaws at any time, even though the bylaws may also be amended at any time by the board of directors. Under Delaware law, stockholders entitled to vote have the power to adopt, amend or repeal bylaws. In addition, a corporation may, in its certificate of incorporation, confer such power upon the board of directors. The stockholders have the power to adopt, amend or repeal bylaws, even though the board may also be delegated such power. E.mergent has, in the E.mergent Certificate, conferred the power to adopt, amend or repeal the E.mergent bylaws upon its directors. The fact that this power has been conferred upon the directors does not divest the stockholders of the power, or limit their power to adopt, amend or repeal the bylaws. Limitation of Liability of Directors The URBCA provides that a director or officer of a Utah corporation is not liable to the corporation or its stockholders for any action taken, or any failure to take any action, as an officer or director, unless (i) the director or officer has breached or failed to perform the duties of the office (which requires that the director or officer acted (A) in good faith, (B) with the care an ordinarily prudent person in like position would exercise under similar circumstances and (C) in a manner the director or officer reasonably believes to be in the best interests of the corporation) and (ii) the breach or failure to perform constitutes gross negligence, willful misconduct or intentional infliction of harm on the corporation or the stockholders. The URBCA permits a corporation to eliminate or limit the liability of a director to the corporation or its stockholders for monetary damages for any action taken or failure to take any action, as a director, except liability for (i) the amount of a financial benefit received by a director to which he is not entitled, (ii) an intentional infliction of harm on the corporation or its stockholders, (iii) voting for or assenting to an unlawful distribution of assets as defined under the URBCA or (iv) an intentional violation of criminal law. The ClearOne Articles provide that to the fullest extent permitted by the URBCA as now, or as it may in the future be, in effect, no director shall be liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director. Delaware law permits a corporation to include a provision in its certificate of incorporation eliminating or limiting the personal liability of a director or officer to the corporation or its stockholders for damages for a breach of the director's fiduciary duty. However, no such provision can eliminate or limit director liability for: o any breach of the director's duty of loyalty to the corporation or it stockholders; o acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of the law; o willful or negligent violation of the laws governing the payment of dividends or the purchase or redemption of stock; and o any transaction from which the director derived an improper personal benefit. E.mergent's Certificate includes such a provision to limit directors' personal liability to the corporation to the maximum extent permitted by law. Indemnification of Directors and Officers The ClearOne bylaws provide that it shall indemnify an individual made a party to a proceeding because he is or was a director, against any liability incurred in the proceeding if (i) the individual's conduct was in good faith, (ii) the individual reasonably believed that his conduct was in, or not opposed to, the corporation's best interests and (iii) in the case of a criminal proceeding he had no reasonable cause to believe his conduct was unlawful; provided, however, that (x) in the case of an action by or in the right of the corporation, indemnification is limited to reasonable expenses incurred in connection with the proceeding and (y) the corporation may not, unless authorized by a court of competent jurisdiction, indemnify an individual (A) in connection with a proceeding by or in the right of the corporation in which the individual was adjudged liable to the corporation or (B) in connection with any other proceeding in which the individual is adjudged liable on the basis that he derived an improper personal benefit. In a judicial proceeding under the foregoing clause (y), in order to authorize indemnification the court must determine that the individual is fairly and reasonably entitled to indemnification in view of all the relevant circumstances. A director is 69

entitled to mandatory indemnification if he was successful, on the merits or otherwise, in the defense of any proceeding, or in the defense of any claim, issue or matter in the proceeding, against the reasonable expenses incurred by him in connection with the proceeding or claim with respect to which he was successful. ClearOne must also advance a director expenses under certain circumstances. ClearOne may also indemnify and advance expenses to an officer, employee, fiduciary or agent to a greater extent if not inconsistent with public policy. Delaware law permits a corporation to indemnify officers and directors for actions taken in good faith and in a manner they reasonably believed to be in, or not opposed to, the best interests of the corporation, and with respect to any criminal action, which they had no reasonable cause to believe was unlawful. Under E.mergent's bylaws, E.mergent commits itself to indemnify each of its directors and officers to the maximum extent and in the manner permitted by Delaware law against expenses (including attorneys' fees), judgments, fines, settlements, and other amounts actually and reasonably incurred in connection with any proceeding, arising by reason of the fact that such person is or was an agent of E.mergent. Furthermore, E.mergent's bylaws authorize it to provide insurance for its directors, officers and/or agents, against any expense, liability or loss, whether or not E.mergent would have the power to indemnify such person against such expense, liability or loss under Delaware law. Dissenters' Rights Under the URBCA, in connection with a merger, share exchange or sale, lease, exchange or other disposition of all or substantially all of the assets of a corporation (other than in the ordinary course of the corporation's business), a dissenting stockholder, after complying with certain procedures, is entitled to payment from the corporation of the fair value of the stockholder's shares. The fair value is estimated by the corporation. However, if the stockholder is unwilling to accept the corporation's estimate, the stockholder may provide the corporation with an estimate of the fair value and demand payment of that amount. If the corporation is unwilling to pay that amount, the corporation shall apply for judicial determination of the fair value. Unless the articles of incorporation, bylaws or a resolution of the board of directors provide otherwise, stockholders are not entitled to dissenters' rights when the shares are listed on a national securities exchange or the Nasdaq National Market, or are held of record by more than 2,000 holders. However, this exception does not apply if, pursuant to the corporate action, the stockholder will receive anything except: (i) shares of the surviving corporation; (ii) shares of a corporation that is or will be listed on a national securities exchange, the Nasdaq National Market, or held of record by more than 2,000 holders; (iii) cash in lieu of fractional shares; or (iv) any combination of the foregoing. Under the DGCL, stockholders are entitled to demand appraisal of their shares in the case of mergers or consolidations, except where: (i) they are stockholders of the surviving corporation and the merger did not require their approval under the DGCL; (ii) the corporation's shares are either listed on a national securities exchange or designated as a national market system security on an inter-dealer quotation system by The National Association of Securities Dealers, Inc.; or (iii) the corporation's shares are held of record by more than 2,000 stockholders. Appraisal rights are not available in either (i), (ii) or (iii) above, however, if the stockholders are required by the terms of the merger or consolidation to accept any consideration other than (a) stock of the corporation surviving or resulting from the merger or consolidation, (b) shares of stock of another corporation which are either listed on a national securities exchange or designated as a national market system security on an interdealer quotation system by The National Association of Securities Dealers, Inc. or held of record by more than 2,000 stockholders, (c) cash in lieu of fractional shares, or (d) any combination of the foregoing. Appraisal rights are not available in the case of a sale, lease, exchange or other disposition by a corporation of all or substantially all of its property and assets. Anti-Takeover Statutes The Utah Control Share Acquisitions Act, set forth in Sections 61-6-1 through 61-6-12 of the Utah Code Annotated, generally provides that, when any person obtains shares (or the power to direct the voting of shares) of "an issuing public corporation" such that the person's voting power equals or exceeds any of three levels (20%, 33 1/3% or 50%), the ability to vote (or to direct the voting of) the "control shares" is conditioned on the approval by a majority of the corporation's shares (voting in voting groups, if applicable), excluding the "interested shares." Stockholder approval may occur at the next annual meeting of the stockholders, or, if the acquiring person requests and agrees to pay the associated costs of the corporation, at a special meeting of the stockholders (to be held within 50 days of the corporation's receipt of the request by an acquiring person). If authorized by the articles of incorporation or the bylaws, the corporation may redeem "control shares" at the fair market value if the acquiring person fails to file an "acquiring person statement" or if the stockholders do not grant voting rights to control shares. The ClearOne Articles and ClearOne bylaws make no reference to the Act. If the stockholders grant voting rights to the control shares, and if the acquiring person obtained a majority of the voting power, stockholders may be entitled to dissenters' 70

rights under the URBCA. An acquisition of shares does not constitute a control share acquisition if (i) the corporation's articles of incorporation of bylaws provide that this Act does not apply (ii) the acquisition is consummated pursuant to a merger in accordance with the URBCA or (iii) under certain other specified circumstances. Delaware has adopted an anti-takeover statute governing takeovers of Delaware corporations. Effective December 31, 1987, a Delaware corporation may not engage in a business combination with any person acquiring 15% or more of the voting stock of such Delaware corporation (an "interested stockholder") for a period of three years following the date of such acquisition, unless: (i) prior to the date the stockholder became an interested stockholder, the board of directors of the corporation approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder; (ii) the interested stockholder acquired 85% or more of the corporation's voting stock in the transaction in which he became an interested stockholder; or (iii) on or subsequent to the date the stockholder became an interested stockholder, the board of directors and stockholders owning two-thirds of the outstanding voting stock, other than the interested stockholder's stock, approve the business combination. The corporation may opt out of the effect of this statute by: (i) including a provision to such effect in the corporation's original certificate of incorporation; (ii) amendment to the corporation's bylaws made by the board of directors; or (iii) amendment of the corporation's certificate of incorporation or bylaws approved by holders of a majority of the shares entitled to vote; provided that such amendment shall not take effect until 12 months after its adoption and shall not effect any business combinations with interested stockholders which are effected during such 12 months. E.mergent has not elected to opt out of the effects of the statute. 71

ANNEX A AGREEMENT AND PLAN OF MERGER This AGREEMENT AND PLAN OF MERGER is made and entered into as of January 21, 2002, by and among CLEARONE COMMUNICATIONS, INC. (formerly, Gentner Communications Corporation), a Utah corporation ("Parent"), TUNDRA ACQUISITION CORPORATION, a Delaware corporation and a wholly-owned subsidiary of Parent ("Merger Sub"), and E.MERGENT, INC., a Delaware corporation (the "Company"). RECITALS A. The Boards of Directors of the Company, Parent and Merger Sub have each (i) determined that the Merger (as defined in Section 1.1) is advisable and fair to and in the best interests of their respective stockholders, (ii) approved the Merger upon the terms and subject to the conditions set forth in this Agreement, and (iii) determined, subject to the terms of this Agreement, to recommend that the stockholders of the Company adopt and approve this Agreement and the Merger; B. In furtherance thereof, it is proposed that Company merge with and into the Merger Sub (the "Merger") and the stock of the Company will thereupon be converted into the right to receive both cash and a fraction of a share of the common stock, par value $0.001, of the Parent (the "Parent Common Stock") in the amounts set forth in Section 1.7(a) hereof; C. Concurrently with the execution of this Agreement, as a condition and inducement to Parent's willingness to enter into this Agreement, certain executive officers and directors of Company, in their capacity as stockholders, are entering into a Voting Agreement in substantially the form attached hereto as Exhibit A (the "Voting Agreement"); D. As a condition and inducement to Parent's willingness to enter into this Agreement, certain affiliates of the Company are entering into Company Affiliate Agreements in substantially the form attached hereto as Exhibit B (the "Company Affiliate Agreements"), at or prior to the consummation of the Merger; and E. The parties hereto intend, by executing this Agreement, to adopt a plan of "reorganization" within the meaning of section 368(a) of the Internal Revenue Code of 1986, as amended (the "Code"). NOW, THEREFORE, in consideration of the foregoing premises and the representations, warranties, covenants and agreements herein contained, and intending to be legally bound hereby, the Company, Parent and Merger Sub hereby agree as follows: ARTICLE I THE MERGER 1.1 The Merger. At the Effective Time (as defined in Section 1.2) and subject to and upon the terms and conditions of this Agreement and the applicable provisions of Delaware Law, the Company shall be merged with and into the Merger Sub, the separate corporate existence of Company shall cease and Merger Sub shall continue as the surviving corporation. Merger Sub as the surviving corporation after the Merger is hereinafter sometimes referred to as the "Surviving Corporation." 1.2 Effective Time; Closing. Subject to the provisions of this Agreement, the parties hereto shall cause the Merger to be consummated by filing the Certificate of Merger with the Secretary of State of the State of Delaware in accordance with the relevant provisions of Delaware Law (the "Merger Certificate") (the time of such filing, or such later time as may be agreed in writing by Company and Parent and specified in the Merger Certificate, being the "Effective Time") as soon as practicable on or after the Closing Date (as herein defined). Unless the context otherwise requires, the term "Agreement" as used herein refers collectively to this Agreement and Plan of Merger and the Merger Certificate. The closing of the Merger (the "Closing") shall take place at the offices of Jones, Waldo, Holbrook & McDonough, 170 South Main Street, Salt Lake City, UT 84101, or at such other location as the parties may agree, and at a time and date to be specified by the parties, which shall be no later than the A-1

second business day after the satisfaction or waiver of the conditions set forth in Article VI, or at such other time, date and location as the parties hereto agree in writing (the "Closing Date"). 1.3 Registration Statement. As soon as practicable after the date of this Agreement, Parent shall prepare and file with the SEC a registration statement on Form S-4 to register the offer and sale of Parent Common Stock pursuant to the Merger (the "Registration Statement"). The Company agrees that the information provided by the Company in writing specifically for inclusion or incorporation by reference in the Registration Statement shall not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. Each of Parent, Merger Sub and the Company agrees promptly to correct any information provided by it for use in the Registration Statement if and to the extent that such information shall have become false or misleading in any material respect. The Company and its counsel shall be given reasonable opportunity to review and comment on the Registration Statement prior to the filing thereof with the SEC. Parent agrees to provide in writing to the Company and its counsel any comments Parent or its counsel may receive from the SEC or its staff with respect to the Registration Statement promptly after receipt of such comments and shall provide Company and its counsel with a reasonable opportunity to participate in the response of Parent to such comments. 1.4 Effect of the Merger. At the Effective Time, the effect of the Merger shall be as provided in this Agreement and the applicable provisions of Delaware Law. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time all the property, rights, privileges, powers and franchises of Company and Merger Sub shall vest in the Surviving Corporation, and all debts, liabilities and duties of Company and Merger Sub shall become the debts, liabilities and duties of the Surviving Corporation. 1.5 Certificate of Incorporation; Bylaws. (a) At the Effective Time, the Certificate of Incorporation of Merger Sub shall be the Certificate of Incorporation of the Surviving Corporation except that it shall be amended to provide that the name of the Surviving Corporation shall be the Company name, or such other name as may be determined by Parent and/or Merger Sub, until thereafter amended in accordance with Delaware Law and such Certificate of Incorporation. (b) The Bylaws of Merger Sub, as in effect immediately prior to the Effective Time, shall be, at the Effective Time, the Bylaws of the Surviving Corporation until thereafter amended. 1.6 Directors and Officers. The initial director of the Surviving Corporation shall be the director of Merger Sub immediately prior to the Effective Time, to hold office in accordance with the Certificate of Incorporation and Bylaws of the Surviving Corporation until his successors are duly elected or appointed and qualified. The initial officers of the Surviving Corporation shall be the officers of Merger Sub immediately prior to the Effective Time, each to hold office in accordance with the Certificate of Incorporation and Bylaws of the Surviving Corporation until their respective successors are duly appointed. 1.7 Effect on Capital Stock. Subject to the terms and conditions of this Agreement, at the Effective Time, by virtue of the Merger and without any action on the part of Merger Sub, Company, or the holders of any of the following securities, the following shall occur: (a) Conversion of Company Common Stock. Each share of Common Stock, $0.01 par value per share, of Company (the "Company Common Stock") issued and outstanding immediately prior to the Effective Time will be canceled and extinguished and automatically converted into the right to receive (x) a cash payment per Share, without any interest thereon (the "Cash Portion"), and (y) a fraction of a share of Parent Common Stock (the "Stock Portion") (the Cash Portion and the Stock Portion, and cash in lieu of fractional shares as specified below, are collectively referred to as the "Merger Consideration") upon surrender of the certificate representing such share of Company Common Stock (each a "Share Certificate"), in the manner provided in Section 1.10 (or in the case of a lost, stolen or destroyed upon delivery of an affidavit (and bond, if required) in the manner provided in Section 1.9). The parties agree that the aggregate Cash Portion shall be $7,300,000 and the aggregate Stock Portion shall be 873,000 shares of Parent Common Stock less the aggregate number of shares of Parent Common Stock allocated to the Company Stock Options (defined below) as provided in A-2

Sections 1.7(c) and 5.8 (the "Parent Option Shares"). Accordingly, the Cash Portion shall be the quotient obtained by dividing (A) $7,300,000 by (B) the total number of shares of Company Common Stock issued and outstanding immediately prior to the Effective Time. The Stock Portion shall be a quotient obtained by dividing (X) the sum of (a) 873,000 minus (b) the Parent Option Shares divided by (Y) the total number of shares of Company Common Stock issued and outstanding immediately prior to the Effective Time. (b) Cancellation of Company-Owned Stock. Each share of Company Common Stock held by Company immediately prior to the Effective Time shall be cancelled and extinguished without any conversion thereof, other than fifty thousand three hundred seventeen (50,317) shares currently held in treasury which will be distributed to Company employees effective immediately prior to the Closing and treated pursuant to Section 1.7(a). (c) Stock Options. At the Effective Time all options to purchase Company Common Stock ("Company Stock Options") then outstanding under the E.mergent Employee Stock Option Plan (the "Company Option Plans") shall be treated in accordance with Section 5.8 hereof. (d) Employee Stock Purchase Plan. All shares outstanding under Company's Employee Stock Purchase Plan (the "ESPP") will be converted as of the Effective Time pursuant to Section 1.7(a), above. Any outstanding employee deposits not applied to the purchase of shares of Company Common Stock will be refunded to the depositing employee. (e) Adjustments to the Stock Portion and the Cash Portion. The Stock Portion and the Cash Portion shall be adjusted appropriately to reflect the effect of any permitted stock split, reverse stock split, stock dividend (including any dividend or distribution of securities convertible into Company Common Stock or Parent Common Stock), extraordinary cash dividends, reorganization, recapitalization, reclassification, combination, exchange of shares or other like change with respect to the Company Common Stock or the Parent Common Stock occurring on or after the date hereof and prior to the Effective Time. (f) Fractional Shares. No fraction of a share of Parent Common Stock will be issued in connection with the payment of the Stock Portion of the Merger Consideration, but in lieu thereof each holder of a Share Certificate who would otherwise be entitled to receive a fraction of a share of Parent Common Stock (after aggregating all fractional shares of Parent Common Stock that otherwise would be received by such holder) in the Merger shall receive from Parent an amount of cash (rounded to the nearest whole cent), without interest, equal to the product obtained by multiplying such fraction by the Average Price. 1.8 Exchange of Certificates. (a) Exchange Agent. Parent shall select an entity reasonably acceptable to Company to act as the exchange agent (the "Exchange Agent") in the Merger. (b) Parent to Provide Cash and Stock. Promptly after the Effective Time, Parent shall make available to the Exchange Agent, for payment in accordance with this Article I, (i) an amount in cash equal to the product of the Cash Portion and the number of shares that are issued and outstanding at the Effective Time and (ii) a number of shares of Parent Common Stock representing the number of shares of Parent Common Stock equal to the product of the Stock Portion and the number of shares issued and outstanding at the Effective Time, and (iii) the cash amount payable in lieu of fractional shares in accordance with Section 1.7(f). Any portion of such cash and stock which remains undistributed to the holders of the Share Certificates for six (6) months after the Effective Time shall be delivered to Parent, upon demand, and any holders of shares of Company Common Stock prior to the Merger who have not theretofore complied with this Article I shall thereafter look for payment, as general creditors thereof, only to Parent for their claim for the Merger Consideration to which such holders may be entitled. (c) Payment Procedures. Promptly after the Effective Time, Parent shall cause the Exchange Agent to mail to each holder of record (as of the Effective Time) of a Share Certificate, which immediately prior to the Effective Time represented outstanding shares of Company Common Stock (i) a letter of transmittal in customary form (which shall specify that delivery A-3

shall be effected, and risk of loss and title to the Share Certificates shall pass, only upon delivery of the Share Certificates to the Exchange Agent, and (ii) instructions for use in effecting the surrender of the Share Certificates in exchange for the Merger Consideration.

To the extent such amounts are so deducted or withheld, such amounts shall be treated for all purposes under this Agreement as having been paid to the person to whom such amounts would otherwise have been paid. (e) No Liability. Notwithstanding anything to the contrary in this Section 1.8, neither the Exchange Agent, Parent, the Surviving Corporation nor any party hereto shall be liable to a holder of shares of Parent Common Stock or Company Common Stock for any amount properly paid to a public official pursuant to any applicable abandoned property, escheat or similar law. 1.9 No Further Ownership Rights in Company Common Stock. From and after the Effective Time, all shares of Company Common Stock shall no longer be outstanding and shall automatically be cancelled, retired and cease to exist and each holder of a Share Certificate representing any such shares shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration therefor upon the surrender thereof in accordance with Section 1.8 hereof. The Merger Consideration issued in accordance with the terms hereof shall be deemed to have been issued in full satisfaction of all rights pertaining to such shares of Company Common Stock. There shall be no further registration of transfers on the records of the Surviving Corporation of shares of Company Common Stock which were outstanding immediately prior to the Effective Time. If, after the Effective Time, Share Certificates are presented to the Surviving Corporation for any reason, they shall be canceled and exchanged as provided in this Article I. 1.10 Lost, Stolen or Destroyed Share Certificates. In the event that any Share Certificates shall have been lost, stolen or destroyed, the Exchange Agent shall issue in exchange for such lost, stolen or destroyed Share Certificates, upon the making of an affidavit of that fact by the holder thereof, the Merger Consideration pursuant to Section 1.7; provided, however, that Parent may, in its discretion and as a condition precedent to the issuance of such Merger Consideration and other distributions, require the owner of such lost, stolen or destroyed Share Certificates to deliver a bond in such sum as it may reasonably direct as indemnity against any claim that may be made against Parent, the Surviving Corporation or the Exchange Agent with respect to the Share Certificates alleged to have been lost, stolen or destroyed.

Such stockholders shall be entitled to receive payment of the appraised value of such shares held by them in accordance with the provisions of such Section 262, except that all Dissenting Shares held by stockholders who shall have failed to perfect or who effectively shall have withdrawn or lost their rights to appraisal of such shares under such Section 262 shall thereupon be deemed to have been converted into, and to have become exchangeable for, as of the Effective Time, the right to receive the Merger Consideration, without any interest thereon, upon surrender, in the manner provided in Section 1.7, of the certificate or certificates that formerly evidenced such shares. (b) The Company shall give Parent (i) prompt notice of any demands for appraisal received by the Company, withdrawals of such demands, and any other instruments served pursuant to Delaware Law and received by the Company and (ii) the opportunity to direct all negotiations and proceedings with respect to demands for appraisal under Delaware Law.

In the case of any holder of a Company Stock Option, the parties shall take reasonable steps (i) to enable the holder thereof to exercise any portion of the option that is either exercisable or that first becomes exercisable in connection with the Merger, or (ii) convert such option to an option in the Parent's 1998 Stock Option Plan as more fully described below. (i) Following the date of execution of this Agreement, and unless the Merger does not close as contemplated by this Agreement, the Company shall make no additional grants of Company Stock Options; (ii) At the Effective Time of the Merger, Parent shall assume the Company Stock Options, and such assumed Company Stock Options will continue to have, and be subject to, the terms and conditions of such options immediately prior to the Effective Time except that (a) each Company Grant will be solely exercisable (or will become exercisable in accordance with its terms) for that number of whole shares of Parent Common Stock equal to the product of the number of shares of Company Common Stock that were issuable upon exercise of such Company Stock Options immediately prior to the Effective Time multiplied by the Option Exchange Ratio, rounded down to the nearest whole number of shares of Parent Common Stock and (b) the per share exercise price for the shares of Parent Common Stock issuable upon exercise of such assumed Company Stock Options will be equal to the quotient determined by dividing the exercise price per share of Company Common Stock at which such Company Stock Option was exercisable immediately prior to the Effective Time by the Option Exchange Ratio, rounded up to the nearest whole cent. Parent shall comply with the terms of all such grants of Company Stock Options. Parent shall take all corporate actions necessary to reserve for issuance a sufficient number of shares of Parent Common Stock for delivery pursuant to the terms set forth in this Section 5.8(a). The "Option Exchange Ratio" shall be determined as follows: Option Exchange Ratio = (TV/ TS) / AP Where TV = The sum of $7,300,000 plus the product of (i) the Average Price (defined below) times (ii) 873,000 ("Transaction Value") TS = The aggregate the number of shares of Company Common Stock and Company Stock Options outstanding immediately prior to the Effective Time AP = The weighted average closing price of the Parent Common Stock for the ten (10) trading days ending one trading day prior to the Closing Date, as quoted on the NASDAQ National Market (the "Average Price")) The parties acknowledge that the formula for the Option Exchange Ratio is intended to exchange a fraction of a share of Parent Common Stock for each for each share of Company Common Stock subject to a Company Stock Option, with the value of such fraction of a share of Parent Common Stock to be approximately equivalent to the aggregate value of the Cash Portion and Stock Portion exchanged for each outstanding share of Company Common Stock, as such value is determined by the Average Price. (b) ESPP. Company shall take all steps necessary to terminate Company's ESPP as soon as practicable following the Closing Date. Any shares of Company Common Stock in the ESPP shall by virtue of the Merger, and without any action on the part of the holder thereof, be converted into the right A-30

to receive the Merger Consideration described in Section 1.7(a), above, without issuance of certificates representing issued and outstanding shares of Company Common Stock to participants under the ESPP. Company shall, prior to the Effective Time, provide Parent with evidence of the termination of the ESPP. 5.9 Employee Benefits. (a) Company shall terminate, effective as of the day immediately preceding the date the Company becomes a member of the same Controlled Group of Corporations (as defined in Section 414(b) of the Code) as the Parent (the "401(k) Termination Date"), any and all 401(k) plans unless Parent provides notice to Company that such 401(k) plan(s) shall not be terminated. Parent shall receive from Company evidence that Company's plan(s) and/or program(s) have been terminated pursuant to resolutions of each such entity's Board of Directors (the form and substance of such resolutions shall be subject to review and approval of Parent), effective as of the 401(k) Termination Date. To the extent permitted by Parent's applicable plan and otherwise practicable, Parent shall take appropriate steps to enable continuing employees to roll over distributions from the terminated plans to a tax-qualified defined contribution plan or plans maintained by Parent or an affiliate. (b) Parent will cause the Surviving Corporation to provide the benefits (including health benefits, severance policies, 401(k) plans and general employment policies and procedures, subject to the terms and conditions of such plans) which are substantially comparable in the aggregate to benefits that are available to similarly situated employees of Parent and its subsidiaries as of the date hereof, provided, however, that such insurance carriers, outside providers or the like are able to provide such benefits on terms reasonably acceptable to Parent, and provided, further, that nothing in this Section 5.8 shall prevent the Surviving Corporation or any of its subsidiaries from making any change required by applicable law, and provided, further, that it shall not result in any duplication of benefits. 5.10 Inspection of Real Property. From and after the date of this Agreement, Parent and its agents, contractors and representatives shall have the right and privilege of entering upon all properties owned or leased by Company and of reviewing Company's books and records regarding such properties from time to time as needed to make any inspections, evaluations, surveys or tests which Parent may reasonably deem necessary or appropriate. Without limiting the generality of the foregoing, Parent and its agents, contractors and representatives shall have the right and privilege of conducting such engineering studies, seismic tests, environmental studies (including, without limitation, surface and subsurface tests, borings and samplings) and surveys of such properties and such feasibility studies as Parent deems necessary or appropriate and to investigate all matters relating to zoning, use and compliance with other applicable laws regarding the use and occupancy of such properties and any proposed impositions, assessments and governmental regulations affecting such properties. Company shall cooperate reasonably with Parent in completing such inspections and evaluations. Parent's exercise of its right to inspect such properties, or Parent's election not to inspect any property, shall in no way be interpreted as a waiver of any of Parent's rights or remedies contained in this Agreement, including, without limitation, Parent's right to rely on Company's representations and warranties made herein. 5.11 Company Affiliate Agreements. Set forth in Section 5.11 of the Company Schedule is a complete and accurate list of those persons who may be deemed to be, in Company's reasonable judgment, affiliates of Company within the meaning of Rule 145 promulgated under the Securities Act (each, a "Company Affiliate"). Company will provide Parent with such information and documents as Parent reasonably requests for purposes of reviewing such list. Company has delivered herewith written Company Affiliate Agreements substantially in the form attached hereto as Exhibit B executed by all Company Affiliates as of the date hereof. Company will use its commercially reasonable efforts to deliver or cause to be delivered to Parent, on or as promptly as practicable following the date hereof, from each Company Affiliate that has not delivered a Company Affiliate Agreement on or prior to the date hereof, an executed Company Affiliate Agreement. Each Company Affiliate Agreement will be in full force and effect as of the Effective Time. Parent will be entitled to place appropriate legends on the certificates evidencing any Parent Common Stock to be received by a Company Affiliate pursuant to the terms of this Agreement, and to issue appropriate stop transfer instructions to the transfer agent for the Parent Common Stock, consistent with the terms of the Company Affiliate Agreement.

Except as provided in Section 1. above, the Merger Agreement shall remain in full force and effect with no amendment or modification. 3. This Amendment Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, regardless of the laws that might otherwise govern under applicable principles of conflicts of law thereof. 4.

The Shares beneficially owned by the undersigned stockholder of the Company as of the date of this Proxy are listed on the final page of this Proxy. Upon the execution of this Proxy by the undersigned, any and all prior proxies given by the undersigned with respect to any Shares are hereby revoked and the undersigned hereby agrees not to grant any subsequent proxies with respect to the Shares until after the Expiration Date (as defined below). This Proxy is irrevocable (to the fullest extent permitted by law), is coupled with an interest and is granted pursuant to that certain Voting Agreement of even date herewith by and between Parent and the undersigned stockholder, and is granted in consideration of Parent entering into that certain Agreement and Plan of Merger (the "Merger Agreement"), by and among Parent, Tundra Acquisition Corporation, a Delaware corporation and a wholly-owned subsidiary of Parent ("Purchaser"), and the Company, which provides for the merger of the Company with and into the Purchaser in accordance with its terms (the "Merger"). As used herein, the term "Expiration Date" shall mean the earlier to occur of (i) such date and time as the Merger Agreement shall have been terminated in accordance with its terms, or (ii) such date and time as the Merger shall become effective in accordance with the terms and conditions set forth in the Merger Agreement.

ANNEX C 18 January 2002 Confidential The Board of Directors E.mergent Corporation 5960 Golden Hills Drive Minneapolis, MN 55416 Re: Fairness Opinion Members of the Board of Directors: You have requested our opinion as to the fairness, from a financial point of view, to the holders of common stock of E.mergent Corporation, a Delaware corporation ("E.mergent" or the "Company"), of the consideration to be received by such shareholders for their common stock pursuant to the terms of a proposed Merger Agreement (the "Merger Agreement") to be executed on or about the date hereof by and among the Company, ClearOne Communications Corporation (formerly Gentner Communications Corporation) ("ClearOne"), and Tundra Acquisition Corporation, a wholly owned subsidiary of ClearOne ("Merger Sub"). All capitalized and undefined terms used herein have the meanings given to them in the Merger Agreement. The Merger Agreement provides for, among other things, the merger of the Company with and into Merger Sub (the "Merger"), as a result of which each share of E.mergent common stock ("Company Common Stock") outstanding on the Closing Date will be converted into the right to receive an amount of cash and shares of common stock of ClearOne ("ClearOne Common Stock") equal to the amounts resulting from dividing each of $7,300,000 cash and 873,000 shares of ClearOne Common Stock by the number of shares of Company Common Stock outstanding on the Closing Date (subject to adjustment, as more fully described in the Merger Agreement) (as so adjusted, the "Consideration"). As a result of the Merger, the Company shall be merged with and into the Merger Sub, with the Merger Sub surviving and remaining a wholly owned subsidiary of ClearOne. We understand that the Merger is intended to qualify as a tax-free reorganization within the meaning of Sections 368(a)(1)(A) and 368(a)(2)(D) of the Internal Revenue Code C-1

of 1986, as amended. The terms and conditions of the Merger are set forth more fully in the Merger Agreement. As a customary part of its investment banking business, Goldsmith, Agio, Helms Securities, Inc. is regularly engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, private placements, and valuations for corporate and other purposes. In return for our services in connection with providing this opinion, the Company will pay us a fee, which fee is not contingent upon the consummation of the Merger, and indemnify us against certain liabilities. We also are acting as the exclusive financial advisor to the Company in connection with the Merger, for which we will receive certain other fees, a significant portion of which is contingent upon the consummation of the Merger. In arriving at our opinion, we have undertaken such reviews, analyses and inquiries as we deemed necessary and appropriate under the circumstances. Among other things, we have (i) reviewed the latest draft of the Merger Agreement, dated January 17, 2002; (ii) reviewed certain financial and other information that is publicly available relating to the Company and ClearOne; (iii) reviewed certain internal financial and operating data of the Company that has been made available to us by the Company; (iv) discussed with senior management of the Company the past and present financial condition, operating results, business outlook and prospects of the Company; (v) discussed with senior management of ClearOne the present financial condition, operating results, and near term business outlook of ClearOne; (vi) reviewed the Company's and ClearOne's historical common stock price trends; (vii) analyzed the stock price premiums paid in recent mergers and acquisitions of publicly traded companies with transaction values ranging from $10 to $50 million, and compared those premiums to the premium implied by the consideration in the Merger; (viii) performed a discounted cash flow analysis of the Company's projected financial performance; (ix) reviewed the valuations of publicly traded companies that we deemed generally comparable to the Company; and (x) reviewed the financial terms of certain transactions we deemed generally similar to the Merger that recently have been effected. We have relied upon and assume, without independent verification, the accuracy and completeness of the financial statements and other information furnished by, or publicly available relating to, the Company and ClearOne, or otherwise made available to us. We have also relied upon the representations and warranties of the Company and other parties thereto contained in the Merger Agreement and have assumed, without independent verification, that they are true and correct. We were not engaged to, and did not attempt to, or assume responsibility to, verify independently such information. We have further relied upon assurances by the C-2

Company that the information provided to us has a reasonable basis, and with respect to projections and other business outlook information, reflects the best currently available estimates and judgments of the future financial performance of the Company, and that the Company is not aware of any information or fact that would make the information provided to us incomplete or misleading. We have also assumed that the Company and ClearOne each will perform all of the covenants and agreements to be performed by it under the Merger Agreement, that the conditions to the Merger set forth in the Merger Agreement would be satisfied and that the Merger would be consummated on a timely basis in the manner contemplated by the Merger Agreement. We have assumed that the executed version of the Merger Agreement will not differ in any material respects from the last draft we reviewed, and that the terms of the consideration to be paid to the holders of the Company Common Stock will be identical to those set forth in the last draft that we reviewed. We have also assumed that, once consummated, the Merger will qualify as a tax-free reorganization for federal income tax purposes. In arriving at our opinion, we have not performed any appraisals or valuations of specific assets or liabilities of the Company, nor have we been furnished with any such appraisals. Our opinion is necessarily based upon the information available to us and the facts and circumstances as they exist and are subject to evaluation on the date hereof, including the financial, economic, market and other conditions as in effect on the date hereof; events and conditions occurring or existing after the date hereof could materially affect the assumptions used in preparing this opinion. Our opinion is rendered for the benefit and use of the Board of Directors of the Company in connection with the Board's consideration of the Merger and does not constitute a recommendation to any holder of Company Common Stock as to how to vote such holder's shares of Company Common Stock in connection with the Merger. We do not opine on, nor does our opinion consider, the tax consequences of the Merger to any holder of Company Common Stock. We have not been asked to, nor do we, express any opinion as to the relative merits of the Merger as compared to any alternative business strategies that might exist for the Company, the effect of any other transaction in which the Company might engage, or the form of the Merger Agreement or the terms contained therein. Furthermore, we express no opinion as to the prices at which either Company Common Stock or ClearOne Common Stock may trade following the date of this opinion. This opinion may not be published or otherwise used or referred to publicly without our written consent; provided, however, that this opinion may be included in its entirety in any filing with the Securities and Exchange Commission with respect to the Merger. C-3

Based upon and subject to the foregoing, it is our opinion that, as of the date hereof, the Consideration to be received by the holders of Company Common Stock in the proposed Merger is fair, from a financial point of view, to such shareholders. Sincerely, Goldsmith, Agio, Helms Securities, Inc. C-4

ANNEX D SECTION 262 OF THE GENERAL CORPORATION LAW OF THE STATE OF DELAWARE Section 262. Appraisal Rights. (a) Any stockholder of a corporation of this State who holds shares of stock on the date of the making of a demand pursuant to subsection (d) of this section with respect to such shares, who continuously holds such shares through the effective date of the merger or consolidation, who has otherwise complied with subsection (d) of this section and who has neither voted in favor of the merger or consolidation nor consented thereto in writing pursuant to ss. 228 of this title shall be entitled to an appraisal by the Court of Chancery of the fair value of the stockholder's shares of stock under the circumstances described in subsections (b) and (c) of this section. As used in this section, the word "stockholder" means a holder of record of stock in a stock corporation and also a member of record of a nonstock corporation; the words "stock" and "share" mean and include what is ordinarily meant by those words and also membership or membership interest of a member of a nonstock corporation; and the words "depository receipt" mean a receipt or other instrument issued by a depository representing an interest in one (1) or more shares, or fractions thereof, solely of stock of a corporation, which stock is deposited with the depository. (b) Appraisal rights shall be available for the shares of any class or series of stock of a constituent corporation in a merger or consolidation to be effected pursuant to ss. 251 (other than a merger effected pursuant to ss. 251(g) of this title), ss. 252, ss. 254, ss. 257, ss. 258, ss. 263 or ss. 264 of this title: (1) Provided, however, that no appraisal rights under this section shall be available for the shares of any class of series of stock, which stock, or depository receipts in respect thereof, at the record date fixed to determine the stockholders entitled to receive notice of and to vote at the meeting of stockholders to act upon the agreement of merger or consolidation, were either (i) listed on a national securities exchange or designated as a national market system security on an interdealer quotation system by the National Association of Securities Dealers, Inc. or (ii) held of record by more than 2,000 holders; and further provided that no appraisal rights shall be available for any shares of stock of the constituent corporation surviving a merger if the merger did not require for its approval the vote of the stockholders of the surviving corporation as provided in subsection (f) of ss. 251 of this title. (2) Notwithstanding paragraph (1) of this subsection, appraisal rights under this section shall be available for the shares of any class or series of stock of a constituent corporation if the holders thereof are required by the terms of an agreement of merger or consolidation pursuant to ss.ss. 251, 252, 254, 257, 258, 263 and 264 of this title to accept for such stock anything except: a. Shares of stock of the corporation surviving or resulting from such merger or consolidation, or depository receipts in respect thereof; b. Shares of stock of any other corporation, or depository receipts in respect thereof, which shares of stock (or depository receipts in respect thereof) or depository receipts at the effective date of the merger or consolidation will be either listed on a national securities exchange or designated as a national market system security on an interdealer quotation system by the National Association of Securities Dealers, Inc. or held of record by more than 2,000 holders; c. Cash in lieu of fractional shares or fractional depository receipts described in the foregoing subparagraphs a. and b. of this paragraph; or d. Any combination of the shares of stock, depository receipts and cash in lieu of fractional shares or fractional depository receipts described in the foregoing subparagraphs a, b and c of this paragraph. (3) In the event all of the stock of a subsidiary Delaware corporation party to a merger effected under ss. 253 of this title is not owned by the parent corporation immediately prior to the merger, appraisal rights shall be available for the shares of the subsidiary Delaware corporation. D-1

(c) Any corporation may provide in its certificate of incorporation that appraisal rights under this section shall be available for the shares of any class or series of its stock as a result of an amendment to its certificate of incorporation, any merger or consolidation in which the corporation is a constituent corporation or the sale of all or substantially all of the assets of the corporation. If the certificate of incorporation contains such a provision, the procedures of this section, including those set forth in subsections (d) and (e) of this section, shall apply as nearly as is practicable. (d) Appraisal rights shall be perfected as follows: (1) If a proposed merger or consolidation for which appraisal rights are provided under this section is to be submitted for approval at a meeting of stockholders, the corporation, not less than 20 days prior to the meeting, shall notify each of its stockholders who was such on the record date for such meeting with respect to shares for which appraisal rights are available pursuant to subsection (b) or (c) hereof that appraisal rights are available for any or all of the shares of the constituent corporations, and shall include in such notice a copy of this section. Each stockholder electing to demand the appraisal of such stockholder's shares shall deliver to the corporation, before the taking of the vote on the merger or consolidation, a written demand for appraisal of such stockholder's shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such stockholder's shares. A proxy or vote against the merger or consolidation shall not constitute such a demand. A stockholder electing to take such action must do so by a separate written demand as herein provided. Within 10 days after the effective date of such merger or consolidation, the surviving or resulting corporation shall notify each stockholder of each constituent corporation who has complied with this subsection and has not voted in favor of or consented to the merger or consolidation of the date that the merger or consolidation has become effective; or (2) If the merger or consolidation was approved pursuant toss. 228 or ss. 253 of this title, each constituent corporation, either before the effective date of the merger or consolidation or within ten days thereafter, shall notify each of the holders of any class or series of stock of such constituent corporation who are entitled to appraisal rights of the approval of the merger or consolidation and that appraisal rights are available for any or all shares of such class of series of stock of such constituent corporation, and shall include in such notice a copy of this section; provided that, if the notice is given on or after the effective date of the merger or consolidation, such notice shall be given by the surviving or resulting corporation to all such holders of any class or series of stock of a constituent corporation that are entitled to appraisal rights. Such notice may, and, if given on or after the effective date of the merger or consolidation, shall, also notify such stockholders of the effective date of the merger or consolidation. Any stockholder entitled to appraisal rights may, within 20 days after the date of mailing of such notice, demand in writing from the surviving or resulting corporation the appraisal of such holder's shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such holder's shares. If such notice did not notify stockholders of the effective date of the merger or consolidation, either (i) each such constituent corporation shall send a second notice before the effective date of the merger or consolidation notifying each of the holders of any class or series of stock of such constituent corporation that are entitled to appraisal rights of the effective date of the merger or consolidation or (ii) the surviving or resulting corporation shall send such a second notice to all such holders on or within 10 days after such effective date; provided, however, that if such second notice is sent more than 20 days following the sending of the first notice, such second notice need only be sent to each stockholder who is entitled to appraisal rights and who has demanded appraisal of such holder's shares in accordance with this subsection. An affidavit of the secretary or assistant secretary or of the transfer agent of the corporation that is required to give either notice that such notice has been given shall, in the absence of fraud, be prima facie evidence of the facts stated therein. For purposes of determining the stockholders entitled to receive either notice, each constituent corporation may fix, in advance, a record date that shall be not more than 10 days prior to the date the notice is given, provided that if the notice is given on or after the effective date of the merger or consolidation, the record date shall be such effective date. If no record date is fixed and the notice is given prior to the effective date, the record date shall be the close of business on the day next preceding the day on which the notice is given. D-2

(e) Within 120 days after the effective date of the merger or consolidation, the surviving or resulting corporation or any stockholder who has complied with subsections (a) and (d) hereof and who is otherwise entitled to appraisal rights, may file a petition in the Court of Chancery demanding a determination of the value of the stock of all such stockholders. Notwithstanding the foregoing, at any time within 60 days after the effective date of the merger or consolidation, any stockholder shall have the right to withdraw such stockholder's demand for appraisal and to accept the terms offered upon the merger or consolidation. Within 120 days after the effective date of the merger or consolidation, any stockholder who has complied with the requirements of subsections (a) and (d) hereof, upon written request, shall be entitled to receive from the corporation surviving the merger or resulting from the consolidation a statement setting forth the aggregate number of shares not voted in favor of the merger or consolidation and with respect to which demands for appraisal have been received and the aggregate number of holders of such shares. Such written statement shall be mailed to the stockholder within 10 days after such stockholder's written request for such a statement is received by the surviving or resulting corporation or within 10 days after expiration of the period for delivery of demands for appraisal under subsection (d) hereof, whichever is later. (f) Upon the filing of any such petition by a stockholder, service of a copy thereof shall be made upon the surviving or resulting corporation, which shall within 20 days after such service file in the office of the Register in Chancery in which the petition was filed a duly verified list containing the names and addresses of all stockholders who have demanded payment for their shares and with whom agreements as to the value of their shares have not been reached by the surviving or resulting corporation. If the petition shall be filed by the surviving or resulting corporation, the petition shall be accompanied by such a duly verified list. The Register in Chancery, if so ordered by the Court, shall give notice of the time and place fixed for the hearing of such petition by registered or certified mail to the surviving or resulting corporation and to the stockholders shown on the list at the addresses therein stated. Such notice shall also be given by 1 or more publications at least 1 week before the day of the hearing in a newspaper of general circulation published in the City of Wilmington, Delaware or such publication as the Court deems advisable. The forms of the notices by mail and by publication shall be approved by the Court, and the costs thereof shall be borne by the surviving or resulting corporation. (g) At the hearing on such petition, the Court shall determine the stockholders who have complied with this section and who have become entitled to appraisal rights. The Court may require the stockholders who have demanded an appraisal for their shares and who hold stock represented by certificates to submit their certificates of stock to the Register in Chancery for notation thereon of the pendency of the appraisal proceedings; and if any stockholder fails to comply with such direction, the Court may dismiss the proceedings as to such stockholder. (h) After determining the stockholders entitled to an appraisal, the Court shall appraise the shares, determining their fair value exclusive of any element of value arising from the accomplishment or expectation of the merger or consolidation, together with a fair rate of interest, if any, to be paid upon the amount determined to be the fair value. In determining such fair value, the Court shall take into account all relevant factors. In determining the fair rate of interest, the Court may consider all relevant factors, including the rate of interest which the surviving or resulting corporation would have had to pay to borrow money during the pendency of the proceeding. Upon application by the surviving or resulting corporation or by any stockholder entitled to participate in the appraisal proceeding, the Court may, in its discretion, permit discovery or other pretrial proceedings and may proceed to trial upon the appraisal prior to the final determination of the stockholder entitled to an appraisal. Any stockholder whose name appears on the list filed by the surviving or resulting corporation pursuant to subsection (f) of this section and who has submitted such stockholder's certificates of stock to the Register in Chancery, if such is required, may participate fully in all proceedings until it is finally determined that such stockholder is not entitled to appraisal rights under this section. (i) The Court shall direct the payment of the fair value of the shares, together with interest, if any, by the surviving or resulting corporation to the stockholders entitled thereto. Interest may be simple or compound, as the Court may direct. Payment shall be so made to each such stockholder, in the case of holders of uncertificated stock forthwith, and the case of holders of shares represented by certificates upon the surrender to the corporation of the certificates representing such stock. The Court's decree may be enforced as other decrees in the Court of Chancery may be enforced, whether such surviving or resulting corporation be a corporation of this State or of any state. D-3

(j) The costs of the proceeding may be determined by the Court and taxed upon the parties as the Court deems equitable in the circumstances. Upon application of a stockholder, the Court may order all or a portion of the expenses incurred by any stockholder in connection with the appraisal proceeding, including, without limitation, reasonable attorney's fees and the fees and expenses of experts, to be charged pro rata against the value of all the shares entitled to an appraisal. (k) From and after the effective date of the merger or consolidation, no stockholder who has demanded appraisal rights as provided in subsection (d) of this section shall be entitled to vote such stock for any purpose or to receive payment of dividends or other distributions on the stock (except dividends or other distributions payable to stockholders of record at a date which is prior to the effective date of the merger or consolidation); provided, however, that if no petition for an appraisal shall be filed within the time provided in subsection (e) of this section, or if such stockholder shall deliver to the surviving or resulting corporation a written withdrawal of such stockholder's demand for an appraisal and an acceptance of the merger or consolidation, either within 60 days after the effective date of the merger or consolidation as provided in subsection (e) of this section or thereafter with the written approval of the corporation, then the right of such stockholder to an appraisal shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery shall be dismissed as to any stockholder without the approval of the Court, and such approval may be conditioned upon such terms as the Court deems just. (1) The shares of the surviving or resulting corporation to which the shares of such objecting stockholders would have been converted had they asserted to the merger or consolidation shall have the status of authorized and unissued shares of the surviving or resulting corporation. D-4

PART II INFORMATION NOT REQUIRED IN PROSPECTUS ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS. ClearOne's Articles of Incorporation provide for the mandatory indemnification of ClearOne's directors to the fullest extent permitted by the Utah Revised Business Corporation Act ("URBCA"). The liability of directors and officers of ClearOne is limited such that a director or officer is not liable to ClearOne or its stockholders for any action taken or any failure to take any action, as an officer or director, as the case may be, unless: (i) the director or officer has breached or failed to perform the duties of the office in compliance with Section 841 of the URBCA; and (ii) the breach or failure to perform constitutes gross negligence, willful misconduct, or intentional infliction of harm on ClearOne or its stockholders. If a director of ClearOne votes for or assents to an distribution prohibited under the URBCA or ClearOne's Articles of Incorporation, the director is personally liable to ClearOne for the prohibited amount of the distribution. ClearOne will, pursuant to Section 902 of the URBCA, indemnify an individual, made party to a proceeding because he was a director, against liability incurred in the proceeding if: (i) the director's conduct was in good faith; (ii) the director reasonably believed that his conduct was in, or not opposed to, ClearOne's best interests; and (iii) in the case of any criminal proceeding, he had no reasonable cause to believe his conduct was unlawful; provided that, the company may not indemnify the same director if (a) indemnification is sought in connection with a proceeding by or in the right of ClearOne in which the director was adjudged liable to ClearOne or (b) indemnification is sought in connection with any other proceeding charging that the director derived an impersonal personal benefit, whether or not including action in his official capacity, in which proceeding he was adjudged liable on the basis that he derived an improper personal benefit. Indemnification in connection with a proceeding by or in the right of ClearOne is limited to reasonable expenses incurred in connection with the proceeding. In accordance with Section 903 of the URBCA ClearOne must indemnify a director, who is successful on the merits or otherwise, in defense of any proceeding, or in the defense of any claim, issue or matter in the proceeding, to which he was a party because he is or was a director of ClearOne, as the case may be, against reasonable expenses incurred by him in connection with the proceeding or claim with respect to which he has been successful. In accordance with Section 904 of the URBCA, ClearOne will pay or reimburse the reasonable expenses incurred by a party to a proceeding in advance of the final disposition of the proceeding, provided that, (i) the director furnishes the corporation a written affirmation of his good faith belief that he has met the applicable standard of conduct described in Section 902 of the URBCA; (ii) the director furnishes to ClearOne a written undertaking, executed personally or on his behalf, to repay the advance if it is ultimately determined that he did not meet such standard of conduct; and (iii) a determination is made that the facts then known to those making the determination would not preclude indemnification under the URBCA. Section 16-10a-905 permits a director or officer who is or was a party to a proceeding to apply for indemnification to the court conducting the proceeding or another court of competent jurisdiction. A court may order indemnification if it is required under Section 903 of the URBCA, or in other circumstances if deem fair and reasonable to do so. ClearOne may indemnify and advance expenses to an officer, employee, fiduciary or agent of ClearOne to the extent consistent with public policy, as determined by the board of directors. ClearOne maintains a directors' and officers' liability insurance policy which, subject to the limitations and exclusions stated therein, covers the officers and directors of ClearOne for certain actions or inactions that they may take or omit to take in their capacities as officers and directors of ClearOne. Insofar as indemnification for liabilities arising under the Securities Act, as amended, may be permitted to officers and directors under any of the foregoing provisions, ClearOne has been informed that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933, as amended, and is therefore unenforceable.

UNDERTAKINGS The undersigned registrant hereby undertakes: (1) that, for purposes of determining any liability under Securities Act of 1933, each filing of the registrant's annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof; (2) that prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other items of the applicable form; (3) that every prospectus (i) that is filed pursuant to paragraph (2) immediately preceding, or (ii) that purports to meet the requirements of Section 10(a)(3) of the Act and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof; (4) to respond to requests for information that is incorporated by reference into the prospectus pursuant to Items 4, 10(b), 11, or 13 of this Form, within one business day of receipt of such request and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request; and (5) to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective. Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the provisions described in Item 20 above, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer, or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.

Re:     Agreement and Plan of Merger, dated January 21, 2002 between ClearOne
Communications, Inc., Tundra Acquisition Corporation and E.mergent Inc.

Ladies and Gentlemen:

        We have acted as counsel to ClearOne Communications, Inc., a Utah
corporation ("ClearOne") in connection with the Agreement and Plan of Merger
(the "Merger Agreement") dated as of January 21, 2002 between E.mergent, Inc.
("E.mergent"), a Delaware corporation, ClearOne, and Tundra Acquisition
Corporation, a Delaware corporation and a wholly owned subsidiary of ClearOne
("Merger Sub"), pursuant to which E.mergent shall be merged with and into
MegerSub with MergerSub the surviving corporation in the merger (the "Merger"),
on the terms and conditions set forth therein, the time at which the Merger
become effective being hereafter referred to as the "Effective Time." For
purposes of this opinion, capitalized terms used and not otherwise defined
herein shall have the meaning ascribed thereto in the Merger Agreement. This
opinion is being delivered solely in connection with ClearOne's Registration
Statement on Form S-4 relating to the proposed Merger pursuant to the Merger
Agreement (the "Registration Statement") to which this opinion appears as an
exhibit.

        In acting as counsel to ClearOne in connection with the Merger, we have,
in preparing our opinion, as hereinafter set forth, participated in the
preparation of the Merger Agreement and the preparation and filing of the
Registration Statement.

        You have requested that we render the opinion set forth below. In
rendering such opinion, we have assumed with your consent that (i) the Merger
will be effected in accordance with the Merger Agreement, (ii) the statements
concerning the Merger set forth in the Merger Agreement and the Registration
Statement are true, complete and correct and will remain true, complete and
correct at all times up to and including the Effective Time, (iii) the factual
representations made by ClearOne, E.mergent and Merger Sub in their respective
letters delivered to us for purposes of this opinion (the "Representation
Letters") are true, complete and correct and will remain true, complete and
correct at all times up to and including the Effective Time, and (iv) any
representations made in the Representation Letters "to the knowledge of," or
based on the belief of, ClearOne, E.mergent and Merger Sub or similarly
qualified are true, complete and correct without such qualification. We have
also assumed that the parties have complied with and, if applicable, will
continue to comply with, the covenants contained in the Merger Agreement.

        We have examined the documents referred to above and the originals, or
duplicates or certified or conformed copies, of such records, documents,
certificates or other instruments and made such other inquiries as in our
judgment are necessary or appropriate to enable us to render the opinion set
forth below. We have not, however, undertaken any independent investigation of
any factual matter set forth in any of the foregoing.

       If any of the above-described assumptions are untrue for any reason or if
the Merger is effected on a factual basis different from that contemplated in
the Merger Agreement and the Registration Statement, the opinion expressed
herein may be inapplicable. Our opinion is based on the Internal Revenue Code of
1986, as amended (the "Code"), Treasury Regulations, administrative
interpretations, and judicial precedents as of the date hereof. If there is any
subsequent change in the applicable law or regulations, or if there are
subsequently any new applicable administrative or judicial interpretations of
the law or regulations, the opinion expressed herein may become inapplicable.

        Based on and subject to the foregoing, we hereby confirm our opinion set
forth in the discussion contained in the Registration Statement under the
caption "Material U.S. Federal Income Tax Consequences."

        We express our opinion herein only as to those matters specifically set
forth in the Registration Statement and no opinion should be inferred as to the
tax consequences of the Merger under any state, local or foreign law, or with


respect to other areas of United States federal taxation. We are members of the Bar of the State of Utah, and we do not express any opinion herein concerning any law other than the federal law of the United States. We hereby consent to the filing of this opinion as an exhibit to the Registration Statement, and to the references to our firm name wherever appearing in the Registration Statement with respect to the discussion of the material U.S. Federal income tax consequences of the Merger, including the proxy statement/prospectus constituting a party thereof. In giving this consent, we do not thereby admit that we in the category of persons whose consent is required under Section 7 of the Securities Act of 1933, as amended, or the rules and regulations of the Securities and Exchange Commission thereunder, nor do we thereby admit that we are experts with respect to any part of such Registration Statement within the meaning of the term "experts" as used in the Securities Act of 1933, as amended, or the rules and regulations of the Securities and Exchange Commission thereunder. Very truly yours, JONES WALDO HOLBROOK & MCDONOUGH, P.C. /s/ Jones Waldo Holbrook & McDonough, P.C.

             "Merger Agreement")

Ladies and Gentlemen:

        We have acted as counsel to E.mergent, Inc. ("E.mergent"), a Delaware
corporation, in connection with (i) the proposed merger (the "Merger") of
E.mergent with and into Tundra Acquisition Corporation ("Merger Sub"), a
Delaware corporation, which is a wholly-owned subsidiary of ClearOne
Communications, Inc. (f/k/a Gentner Communications Corporation), a Utah
corporation ("ClearOne"), and the surviving corporation in the Merger; and (ii)
ClearOne's filing of a Registration Statement on Form S-4 (the "Registration
Statement") relating to the registration under the Securities Act of 1933, as
amended (the "1933 Act"), of up to 873,000 shares of Common Stock of ClearOne
(the "ClearOne Shares"). Pursuant to the Merger Agreement, in the Merger the
shareholders of E.mergent will receive, in exchange for their shares of stock of
E.mergent ("E.mergent Shares"), merger consideration (the "Merger
Consideration") consisting of (i) an aggregate of $7,300,000 in cash (the "Cash
Portion") and (ii) an aggregate of 873,000 ClearOne Shares (the "Stock
Portion"). No other consideration will be received for their E.mergent Shares,
except that cash will be paid to E.mergent shareholders in lieu of any
fractional ClearOne Shares that they would otherwise receive in the Merger.

        You have requested our opinion with respect to the material United
States federal income tax consequences of the Merger. The Merger is being
consummated pursuant to the Merger Agreement. Unless otherwise defined,
capitalized terms used herein have the meanings assigned to them in the Merger
Agreement.

        In connection with rendering our opinion, we have reviewed the Merger
Agreement, including the Exhibits thereto, the Proxy Statement/Prospectus
constituting part of the Registration Statement filed by ClearOne with the
Securities and Exchange Commission on February 6, 2002, and such other documents
and corporate records as we have deemed necessary or appropriate as a basis
therefor. We have assumed that the representations and warranties contained in
the Merger Agreement were true, correct and complete when made and will continue
to be true, correct and complete through the Effective Time, and that the
parties have complied with and, if applicable, will continue to comply with the
covenants contained in the Merger Agreement. We also have assumed that
statements as to factual matters contained in the Proxy Statement/Prospectus are
true, correct, and complete and will continue to be true, correct, and complete
through the Effective Time. Finally, we have relied on the factual
representations made by officers of E.mergent and ClearOne in tax certificates
provided to us dated March 15, 2002, and we have assumed that such
representations will continue to be true, correct, and complete through the
Effective Time.

        Based upon the foregoing, in reliance thereon and subject thereto, and
based upon the Internal Revenue Code of 1986, as amended (the "Code"), the
Treasury Regulations promulgated thereunder, judicial decisions, revenue rulings
and revenue procedures of the Internal Revenue Service, and other administrative
pronouncements, all as in effect on the date hereof, and assuming that the
Merger and related transactions will be consummated in accordance with the terms
of the Merger Agreement, it is our opinion that the Merger will qualify as a
reorganization within the meaning of Section 368(a) by virtue of Section
368(a)(2)(D) of the Code, and that each of Emergent, ClearOne and Merger Sub
will be a party to such reorganization within the meaning of Section 368(b) of
the Code. Furthermore, we hereby confirm that the discussion set forth under the
caption "Material U.S. Federal Income Tax Consequences" in the Proxy
Statement/Prospectus, insofar as such discussion constitutes statements of
United States federal income tax law or legal conclusions, subject to the
assumptions, limitations and qualifications set forth therein, accurately
reflects our opinion of the material United States federal income tax
consequences of the Merger.

        No opinion is expressed as to any matter not specifically addressed
above, including the accuracy of the representations or reasonableness of the
assumptions relied upon by us in rendering the opinion set forth above. Our
opinion is based on current United States federal income tax law and
administrative practice, and we do not undertake to advise you as to any future

changes in United States federal income tax law or administrative practice that may affect our opinion unless we are specifically retained to do so. We consent to the use of this opinion as an Exhibit to the Registration Statement that includes the Proxy Statement/Prospectus, and to the references to Fredrikson & Byron, P.A. under the captions "The Transaction--Material Federal Income Tax Consequences" and "Legal Opinions" in the Proxy Statement/Prospectus. In giving our consent, we do not admit that we are "experts" within the meaning of Section 11 of the Securities Act of 1933 or within the category of persons whose consent is required by Section 7 of the Securities Act of 1933. Very truly yours, FREDRIKSON & BYRON, P.A. /s/ Robert Riberio
