(a) all obligations or liabilities of Seller to be performed on or after the Effective Date under those Contracts or Permits that are Acquired Assets, in each case solely to the extent legally assigned to Purchaser (other than with respect to the Restricted Contracts), provided such obligations under such Contracts or Permits (including the Restricted Contracts), to the extent required by GAAP, are reflected on the Closing Date Balance Statement and taken into account in the determination of the Final Net Working Capital. Notwithstanding the foregoing, obligations or liabilities arising from or related to any default, breach or violation of any such Contract or Permit (including Restricted Contracts) on or prior to the Effective Date, will not constitute a portion of the Assumed Liabilities. The parties acknowledge that performance obligations not involving payment obligations under Customer Service Contracts (including the Restricted Contracts) accruing on or after the Effective Date will not be taken into account in determining Final Net Working Capital because such obligations are not required to be recognized under GAAP. The obligation to perform services pursuant to such Customer Service Contracts that are part of the Acquired Assets shall be included in the Assumed Liabilities; (b) accounts payable and accrued expenses, including accrued salaries, wages, payroll and insurance withholding and accrued vacation obligations of or with respect to Hired Employees, that are current liabilities of Seller arising in the ordinary course of the Conferencing Business, consistent with past practices, in the amounts set forth on Schedule 1.3(b) but solely to the extent reflected on the Closing Date Balance Statement and taken into account in the determination of the Final Net Working Capital; (c) accrued excise and state taxes in the amounts set forth on Schedule 1.3(c) but solely to the extent reflected on the Closing Date Balance Statement and taken into account in the determination of the Final Net Working Capital; (d) the liabilities listed on Schedule 1.3(d), but solely to the extent reflected on the Closing Date Balance Statement and taken into account in the determination of the Final Net Working Capital; and (e) the liabilities, if any, for WARN Act obligations assumed pursuant to Section 5.1(g). 1.4 No Other Liabilities Assumed. (a) Notwithstanding anything in this Agreement to the contrary, neither Purchaser nor any of its Affiliates shall assume and in no event shall be deemed to have assumed, any Liability of Seller or any of its Affiliates whatsoever (collectively, the "Retained Liabilities"), other than as specifically set forth in Section 1.3. The liabilities retained by Seller are herein referred to as the Retained Liabilities. Without limiting the generality of the foregoing, Purchaser is assuming no obligation for, and shall have no responsibility with respect to, Taxes (other than sales, real estate (to the extent assumed under the Sublease) and personal property taxes not yet payable that shall be pro-rated between Purchaser and Seller as of the Effective Date and those Taxes referenced in Section 1.3(c)), liabilities under Environmental Laws or Benefit Plans.

(b) Notwithstanding any other provision of this Agreement, the obligations of Seller and Purchaser pursuant to this section shall survive the Effective Date and the transactions contemplated by this Agreement.

(a) Except as otherwise provided in Section 1.5(b), if there are any Consents that have not yet been obtained (or otherwise are not in full force and effect) as of the Closing, with respect to any Permits which comprise a portion of the Acquired Assets or any other property or right included in the Assumed Liabilities or the Acquired Assets as to which such Consents were not obtained (or otherwise are not in full force and effect) (collectively, the "Restricted Assets"), then notwithstanding Section 1.1, Section 1.3 and Section 3.5, neither this Agreement nor the Assignment and Assumption Agreement nor any other document related to the consummation of the Acquisition shall constitute a sale, conveyance, assignment, transfer or delivery or an attempted sale, conveyance, assignment, transfer or delivery of the Restricted Assets, and following the Closing, the parties shall use commercially reasonable efforts, and cooperate with each other, to obtain the Consent relating to each Restricted Assets as quickly as practicable. Pending the obtaining of such Consents relating to any Restricted Asset, the parties shall cooperate with each other in any reasonable and lawful arrangements designed to provide to Purchaser the benefits of use of the Restricted Asset for its term (or any right or benefit arising thereunder, including the enforcement for the benefit of Purchaser of any and all rights of Seller against a third party thereunder). Once a Consent for the sale, conveyance, assignment, transfer and delivery of a Restricted Asset is obtained, Seller shall (for no additional consideration hereunder) promptly convey, assign, transfer and deliver such Restricted Asset to Purchaser, and Purchaser shall assume the obligations under such Restricted Asset assigned to Purchaser from and after the date of assignment to Purchaser. (b) If there are any Consents necessary for the assignment and transfer of any Contracts (other than the Material Customer Contracts) (the "Nonmaterial Consents") that have not yet been obtained (or otherwise are not in full force and effect) as of the Closing (the "Restricted Contracts"), Purchaser shall accept the assignment of such Restricted Contracts, in which case, as between Seller and Purchaser, such Restricted Contracts shall, to the maximum extent practicable and notwithstanding the failure to obtain the applicable Nonmaterial Consent, be transferred at the Closing pursuant to the Assignment and Assumption Agreement.

ARTICLE II PURCHASE PRICE 2.1 Purchase Price. The aggregate purchase price for the Acquired Assets shall be $21,500,000, plus the assumption of the Assumed Liabilities (the "Purchase Price"), subject to adjustment as provided in Section 2.4. 2.2 Payment of the Purchase Price. The Purchase Price shall be paid by Purchaser to Seller at the Closing by: (a) assumption of the Assumed Liabilities; (b) delivery of the Escrow Amount in readily available funds to the Escrow Agent as provided in Section 2.3; and (c) delivery to Seller of the Closing Date Adjusted Purchase Price, less the Escrow Amount. 2.3 Escrow. At Closing, Purchaser shall deposit an amount equal to $1,300,000 (the "Escrow Amount") with an escrow agent jointly selected by Purchaser and Seller (the "Escrow Agent"), which amount shall be withheld from the Purchase Price. The parties acknowledge and agree that $300,000 of the Escrow Amount shall be used for the purpose of securing the post-Closing purchase price adjustment set forth in Section 2.4 (the "Working Capital Escrow Amount") and $1,000,000 of the Escrow Amount shall be used for the purpose of securing the Seller's indemnification obligations pursuant to Section 7.2 (the "Indemnity Escrow Amount"). The Escrow Amount shall be administered in accordance with the provisions of an Escrow Agreement in the form attached hereto as Exhibit A (the "Escrow Agreement"). The Escrow Amount shall be held as a trust fund and shall not be subject to any lien, attachment, trustee process or any other judicial process of any creditor of any party and shall be held and disbursed solely for the purposes and in accordance with the respective terms thereof. 2.4 Net Working Capital Purchase Price Adjustments. The Purchase Price shall be subject to adjustment as follows: (a) At the Closing, Seller shall deliver to Purchaser a statement of selected balance sheet items (the "Closing Date Balance Statement") with respect to the Conferencing Business as of the Effective Date, which items shall be prepared in accordance with GAAP. The Closing Date Balance Statement shall be accompanied by: (i) all relevant backup materials and schedules along with a certificate from Seller's Chairman of the Board and Controller or Principal Accounting Officer certifying as to the reasonableness of the estimates, all in detail reasonably acceptable to Purchaser; and (ii) a statement setting forth the calculation of the Closing Date Net Working Capital. If the Closing Date Net Working Capital is less than the Net Working Capital Target Amount, the amount of such deficiency shall be deducted from the Purchase Price at the Closing. The Purchase Price, as adjusted pursuant to this section shall be deemed to be the "Closing Date Adjusted Purchase Price." (b) Within ninety (90) days of the Effective Date, Purchaser will review the Closing Date Balance Statement and the calculation of the Closing Date Net Working Capital and if Purchaser disputes the calculation of Closing Date Net Working Capital, Purchaser shall notify Seller in writing (the "Dispute Notice") of the amount, nature and basis of such dispute. Seller shall have twenty (20) Business Days from the receipt of the Dispute Notice to dispute Purchaser's adjustment to the Closing Date Net Working Capital. If Seller fails to dispute such adjustment, then the adjustment shall be final and conclusive. - 6 -

In the event of a dispute, Purchaser and Seller shall first use their diligent good faith efforts to resolve such dispute between themselves. If the parties are unable to resolve the dispute within thirty (30) Business Days after delivery of the Dispute Notice, then any remaining items in dispute shall be submitted to an independent nationally recognized accounting firm selected in writing by Purchaser and Seller or, if Purchaser and Seller fail or refuse to select a firm within ten (10) calendar days after written request therefor by Purchaser or Seller, such an independent nationally recognized accounting firm shall be selected in accordance with the rules of the American Arbitration Association (the "Chosen Firm"). All determinations pursuant to this section shall be in writing and shall be delivered to the parties. The determination of the Chosen Firm as to the resolution of any dispute shall be binding and conclusive upon all parties. A judgment on the determination made by the Chosen Firm pursuant to this section may be entered in and enforced by any court having jurisdiction thereover. The fees and expenses of the Chosen Firm in connection with the resolution of disputes pursuant to this section shall be shared equally by Purchaser and Seller; provided, however, that if the Chosen Firm determines that one party has adopted a position or positions with respect to the calculation of Closing Date Net Working Capital that is frivolous or clearly without merit, the Chosen Firm may, in its discretion, assign a greater portion of any such fees and expenses to such party. The final amount of the Closing Date Net Working Capital as determined pursuant to this section shall be the "Final Net Working Capital." (c) Payments on Account of Adjustments. If the Final Net Working Capital is less than the Closing Date Net Working Capital, then the Escrow Agent shall pay the difference to Purchaser from the Working Capital Escrow Amount in accordance with the terms of the Escrow Agreement. If the amount of the difference between the Final Working Capital and the Closing Date Net Working Capital exceeds the Working Capital Escrow Amount, then Seller shall immediately pay such additional amount in cash to Purchaser. 2.5 Method of Payment. The payments being made from one party to another under this Agreement are being made by wire transfer of immediately available federal funds in United States dollars to an account previously designated in writing by the party to receive such payment. 2.6 Allocation of Purchase Price. Within thirty (30) days from the Effective Date, the parties shall allocate the Purchase Price among the Acquired Assets and such allocation shall be attached to this Agreement as Schedule 2.6. Such allocation is intended to comply with the requirements of Section 1060 of the Internal Revenue Code of 1986, as amended. Seller and Purchaser shall file Form 8594 with their respective Tax Returns consistent with such allocation. The parties shall treat and report the transaction contemplated by this Agreement in all respects consistently for purposes of any Federal, state or local tax, including the calculation of gain, loss and basis with reference to the Purchase Price allocation made pursuant to this Section 2.6. The parties shall not take any action or position inconsistent with the obligations set forth in this Agreement. Seller agrees to indemnify and hold Purchaser and its Affiliates harmless and Purchaser hereby agrees to indemnify and hold Seller harmless, from and against any and all losses, liabilities and expenses (including additional income taxes and reasonable fees and disbursements of counsel) that may be incurred by the indemnified party as a result of the failure of the indemnifying party so to report the sale and purchase of the Acquired Assets as required by applicable Laws. - 7 -

The foregoing notwithstanding, at least five (5) business days prior to the making of any such payment, Purchaser shall notify Seller in writing of its intent to make such payment. If Seller reasonably and in good faith believes that such payment is not owing, then within five (5) business days of its receipt of the same, it may communicate the same to Purchaser in writing. Purchaser shall be free to pay or not pay such Liability, but to the extent it pays any amount which Seller disputes in writing, it shall only be entitled to reimbursement from Seller if the alleged underlying obligation is ultimately determined to have been owing pursuant to the arbitration provisions of Article X, or if compulsory process is necessary to fully determine the validity of such underlying obligation, by a court of appropriate jurisdiction. If Purchaser agrees not to pay any such disputed portion, Seller shall indemnify Purchaser against liability for the same and any damages suffered by Purchaser as a consequence thereof, should it ultimately be determined in the manner provided above that the disputed portion was in fact due and owing. 5.5 Further Assurances.

The representations and warranties of the parties contained in this Agreement or in any other certificate, report or other writing delivered pursuant hereto shall survive until eighteen (18) months after the Effective Date, unless on or before the termination thereof (or of the period set forth below applicable to certain representations and warranties), the complaining party notifies the other party in writing of a claim specifying the factual basis for that claim in reasonable detail; provided, however, that: (a) the representations and warranties set forth at Sections 3.1, 3.2, 3.5, 4.1 and 4.2 shall survive and shall not expire; and (b) the representations and warranties set forth in Sections 3.7, 3.15 and 3.18 shall survive until the ninetieth (90th) day after expiration of the applicable statutes of limitation. 7.2 Indemnification by Seller. (a) Seller agrees to indemnify and defend Purchaser and its Affiliates (the "Purchaser Indemnified Parties") against, and agrees to hold them harmless from, any Losses incurred or suffered by any of the Purchaser Indemnified Parties relating to or arising out of any of the following: (i) any breach of or inaccuracy in any representation or warranty made by Seller pursuant to this Agreement or any certificate, document, writing or instrument delivered by Seller pursuant to this Agreement; (ii) any breach of or failure by Seller to perform any covenant or obligation (including the covenants contained in Article I and Article V) of Seller set out in this Agreement; (iii) any contingent or absolute debt, claim, obligation or other Liability of Seller other than the Assumed Liabilities; (iv) any past, present or future claim by, on behalf of or with respect to, and any obligation or Liability or loss relating to, current or former employees of Seller arising from or related to their employment with Seller, including termination of their employment with Seller, any claim for unfair labor practices or any obligation with respect to any Benefit Plan; (v) any and all Taxes of Seller (including any Taxes owed by Seller following any Restatement Actions), but excluding Taxes which are to be pro-rated hereunder and which Purchaser is required to pay; (vi) any brokerage or finders' fees or commissions or similar payments based upon any agreement or understanding made, or alleged to have been made, by any Person with Seller (or any Person acting on its behalf) in connection with the Acquisition; or (vii) any violation of the Bulk Sales Laws. (b) The Purchaser Indemnified Parties shall be entitled to indemnification under clauses (a)(i) and (a)(ii) of this Section 7.2 only after the aggregate amount of such Losses exceeds $50,000, at which point the Purchaser Indemnified Parties shall be entitled to recover the entire amount of - 23 -

such Losses from the first dollar (including the first $50,000). In no event will the limitation in the immediately preceding sentence apply to the Purchaser Indemnified Parties' right to indemnity under clauses (a)(iii) through (a)(vii) of this Section 7.2. (c) Until eighteen (18) months after the Effective Date (the "Indemnity Period"), the Purchaser may make a claim against the Indemnity Escrow Amount for indemnification pursuant to this Section 7.2. Upon the expiration of the Indemnity Period, the Indemnity Escrow Amount (net of any prior distributions therefrom) shall be disbursed to Seller or its assigns in accordance with the Escrow Agreement; provided, however, any amount claimed by Purchaser pursuant to this Article VII shall not be disbursed pending resolution of the claim in accordance herewith. If Purchaser becomes aware of a claim that it intends to make against the Indemnity Escrow Amount, Purchaser shall give Seller prompt notice, in accordance with Section 11.2, of the claim, specifying the basis therefore ("Escrow Notice"). Seller shall have fifteen (15) Business Days from the receipt of the Escrow Notice to dispute the claim or cure the condition for which such claim has been submitted. If Seller fails to cure the condition or dispute the claim within such fifteen-day period, the claim made by Purchaser against the Indemnity Escrow Amount shall conclusively be deemed a liability of Seller and the amount of such claim may be deducted from the Indemnity Escrow Amount and distributed to the Purchaser pursuant to the terms of the Escrow Agreement. If Seller disputes such claim within the ten-day period, and Seller and Purchaser are unable to reach a settlement of such claim within fifteen (15) days, such dispute shall be resolved by proceedings in accordance with Article X hereof. 7.3 Indemnification by Purchaser and Purchaser's Parent. Purchaser and Purchaser's Parent, joint and severally, agree to indemnify and defend Seller and its Affiliates (the "Seller Indemnified Parties") against, and agree to hold them harmless from, any Losses incurred or suffered by any of the Seller Indemnified Parties relating to or arising out of any of the following: (a) any breach of or any inaccuracy in any representation or warranty made by Purchaser pursuant to this Agreement or any certificate, document, writing or instrument delivered by Purchaser pursuant to this Agreement; (b) any breach of or failure by Purchaser to perform any covenant or obligation of Purchaser set out in this Agreement; (c) the Assumed Liabilities; (d) any claim by, or on behalf of or with respect to, and any obligation or Liability or loss relating to, employees of Purchaser employed in connection with the Conferencing Business and arising after the Effective Date; (e) any brokerage or finders' fees or commissions or similar payments based upon any agreement or understanding made, or alleged to have been made by any Person with Purchaser (or any person acting on its behalf) in connection with the Acquisition; or (f) Taxes which are pro-rated to Purchaser hereunder and which Purchaser is required to pay. - 24 -

7.4 Notice of Claims; Assumption of Defense. The indemnified party shall give prompt notice to the indemnifying party, in accordance with the terms of Section 11.2, of the assertion of any claim, or the commencement of any suit, action or proceeding in respect of which indemnity may be sought hereunder, specifying with reasonable particularity the basis therefor and giving the indemnifying party such information with respect thereto as the indemnifying party may reasonably request (but the giving of such notice shall not be a condition precedent to indemnification hereunder). The indemnifying party may, at its own expense: (a) participate in; and (b) upon notice to the indemnified party and the indemnifying party's written agreement that the indemnified party is entitled to indemnification pursuant to Section 7.2 or Section 7.3 for Losses arising out of such claim, suit, action or proceeding, at any time during the course of any such claim, suit, action or proceeding, assume the defense thereof; provided, that: (i) the indemnifying party's counsel is reasonably satisfactory to the indemnified party and (ii) the indemnifying party shall thereafter consult with the indemnified party upon the indemnified party's request for such consultation from time to time with respect to such claim, suit, action or proceeding. If the indemnifying party assumes such defense, the indemnified party shall have the right (but not the duty) to participate in the defense thereof and to employ counsel, at its own expense, separate from the counsel employed by the indemnifying party. Whether or not the indemnifying party chooses to defend or prosecute any such claim, suit, action or proceeding, the parties hereto shall cooperate in the defense or prosecution thereof. In the event that the indemnifying party elects not to assume the defense of any claim, suit, action or proceeding, such election shall not relieve the indemnifying party of its obligations hereunder. 7.5 Settlement or Compromise. No party shall settle or compromise any claim, suit, action or proceeding without the prior written consent of the other party, which shall not be unreasonably withheld or delayed. Any settlement or compromise made or caused to be made by the indemnified party or the indemnifying party, as the case may be, of any such claim, suit, action or proceeding of the kind referred to in Section 7.4 with the consent of the other party shall also be binding upon the indemnifying party or the indemnified party, as the case may be, in the same manner as if a final judgment or decree had been entered by a court of competent jurisdiction in the amount of such settlement or compromise. 7.6 Liability Limit. Other than in respect of claims arising out of fraud, intentional misrepresentation, willful misconduct or criminal conduct (in which case Purchaser and Seller shall have all remedies available at law or in equity), Purchaser's and Seller's sole remedy hereunder or at law for any loss shall be to seek indemnification pursuant to this Article VII and no party hereunder shall be liable to any other party in connection with any claim for indemnification pursuant to this Article VII for an amount in excess of the Closing Date Adjusted Purchase Price. ARTICLE VIII NON-COMPETITION AND CONFIDENTIALITY 8.1 Acknowledgments and Agreements of Seller. (a) Except as: (i) may be required by a Governmental Authority or applicable Law; (ii) is otherwise expressly permitted by this Agreement; (iii) may be reasonably necessary to permit Seller to wind up any administrative - 25 -

matters pertaining to the Conferencing Business and Seller's employees thereof (the "Administrative Wind-Up"); or (iv) is otherwise expressly permitted in writing by Purchaser, Seller and its Affiliates shall not, for a period of five (5) years beginning on the Effective Date (the "Restricted Period"), in any manner (including electronically, digitally or otherwise) disclose, communicate, transmit, transfer, duplicate, copy or use in its business any Confidential Information, which Seller acknowledges is proprietary to and owned solely by Purchaser, and which shall include the material terms of this Agreement and of any other instrument or agreement delivered pursuant to this Agreement; provided, however, that, the foregoing obligations shall extend beyond the Restricted Period with respect to any Confidential Information that also at that time constitutes a "trade secret" under applicable Law as long as such information continues to remain a trade secret. The parties stipulate that information that is generally known or available to the public or the conferencing services industry other than as a result of unauthorized or unlawful disclosure directly or indirectly by Seller or its Affiliates shall not be deemed to be a "trade secret" or Confidential Information for purposes of this Agreement. Seller shall deliver to Purchaser at any time Purchaser may request, all memoranda, notes, plans, records, reports, computer tapes, printouts and software data and other documents and data (and copies thereof) embodying Confidential Information or relating to the Conferencing Business which Seller may then possess or have under its control, subject to Seller's right to retain copies of the same as may be provided elsewhere herein, solely in order to enable it to comply with applicable Law, to provide evidence of compliance with applicable Law, including maintaining complete and accurate business records, or with respect to the Administrative Wind-Up. (b) If, at the time of enforcement of this Section 8.1, a court shall hold that the duration, scope, or any of the other provisions or restrictions stated herein are unreasonable and therefore unenforceable, the parties agree that the court should partially enforce the provision or restriction to the extent necessary to render the provision or restriction enforceable under applicable Law. (c) Seller acknowledges and agrees that a remedy at law for any breach or threatened breach of the provisions of this Section 8.1 would be inadequate and, therefore, agrees that Purchaser shall be entitled to seek and obtain injunctive relief in addition to any other available rights and remedies in case of any such breach or threatened breach; provided, however, that nothing contained herein shall be construed as prohibiting Purchaser from pursuing any other rights and remedies available for any such breach or threatened breach. 8.2 Non-Competition; Non-Solicitation. (a) In consideration of the Purchase Price and the Assumed Liabilities, during the Restricted Period, Seller and such of its Affiliates (for so long as they are Affiliates) who are not natural persons shall not, directly or indirectly, in any capacity (including as a stockholder, proprietor, partner, joint venturer, member, consultant, trustee, advisor, agent, contractor, lender, or otherwise): (i) own any interest in, manage, control, finance, invest in, consult with, render services for or, subject to Section 8.2(b), engage in any Business Combination with any business located anywhere that provides in North America: (A) operator assisted or reservationless audio conferencing - 26 -

services; (B) video conferencing services; (C) webconferencing services; (D) webcasting services; (E) audio, video and data streaming services; or (F) other services ancillary to the foregoing services, in each case, directly to end users, distributors, dealers, manufacturers' representatives, installers, resellers or agents, with such restriction to include Seller's or its Affiliates' offering any of the foregoing services in connection with the sale of any hardware, equipment and devices (as described below) other than routine installation and maintenance substantially as currently conducted by Seller (any and all such services being the "Restricted Conferencing Business"); provided, however, the Restricted Conferencing Business shall not include: (x) the sale, lease or provision to end users, resellers or agents of audio, visual and web conferencing hardware, software, firmware, equipment and devices, including audio, visual and web conferencing management and distribution devices, microphones, speakers, conference phones, cameras, monitors and use of the foregoing with related conferencing accessories (as long as such sales, leases or provisions are not in conjunction or in any way associated with the direct provision of services by Seller or its Affiliates, including as an application services solutions or managed services solutions provider, that are comprised within the Restricted Conferencing Business); or (y) the provision of consulting or other services other than services which are directly provided by Seller or its Affiliates which are competitive or directly substitutable for the type of services comprised within the Restricted Conferencing Business. The provisions of Section 8.2(a)(i)(x) and Section 8.2(a)(i)(y) are referred to collectively as the "Retained Business." (ii) except: (A) with respect to the right of Seller and its Affiliates to engage in the Retained Business; or (B) on behalf of, and at the direction of, Purchaser or its Affiliates, solicit, divert, sell or accept any Restricted Conferencing Business involving any of the customers of Seller's or Seller's Affiliates' Conferencing Business as of the Effective Date or at any time during the two (2) year period ending on the Effective Date (collectively, the "Restricted Customers"); (iii) except with respect to the right of Seller and its Affiliates to engage in the Retained Business, solicit, induce or attempt to solicit or induce any Restricted Customer, or any supplier, licensee, partner, licensor, consultant, franchisee of Purchaser or any of its Affiliates to cease conducting the Restricted Conferencing Business with Purchaser or any of its Affiliates, or in any way interfere with the Restricted Conferencing Business relationship between: (A) any such Restricted Customer; or (B) any supplier, licensee, partner, licensor, consultant, franchisee, and Purchaser or any of its Affiliates (including making any negative statements or communications about the Restricted Conferencing Business of Purchaser or any of its Affiliates); (iv) solicit, induce or conspire with or attempt to: (A) solicit, induce, or conspire with any employee, officer, contractor or consultant (collectively, the "Restricted Persons") of Purchaser or of any of its Affiliates to sever such Person's affiliation with Purchaser or any of its Affiliates, or to compete against Purchaser or any of its Affiliates, or (B) in any way interfere with the relationship between Purchaser or any of its Affiliates and such Person. Solicitations for employment of a general nature which are not specifically targeted at a Restricted Person shall not violate the foregoing prohibitions, nor shall the hiring of any non-managerial Restricted Person who was not specifically targeted violate the foregoing prohibitions. - 27 -

(b) Within the three (3) year period beginning on the Effective Date (the "Business Combination Restricted Period"), if: (i) Seller engages in a Business Combination; or (ii) a Transferee Affiliate engages in an Affiliate Business Combination, as a condition to consummation of the Business Combination or the Affiliate Business Combination, as the case may be, Seller or the Transferee Affiliate, as the case may be, will cause each Acquiror to agree in writing with Seller or the Transferee Affiliate, as the case may be (the "Acquiror Agreement") to be bound, until the expiration of the Business Combination Restricted Period, by all restrictions of this Article VIII, subject to the additional terms and conditions set forth in Schedule 8.2(b), and the Acquiror Agreement will provide that Purchaser is an express third party beneficiary of Acquiror's agreement to be bound by Article VIII and Schedule 8.2(b). Notwithstanding anything to the contrary in this Agreement, the provisions of Article VIII and Schedule 8.2(b) may be disclosed to any prospective Acquiror as reasonably necessary to facilitate the Acquiror's agreement to be bound by all restrictions of this Article VIII, subject to the additional terms and conditions set forth in Schedule 8.2(b). (c) Notwithstanding anything to the contrary in Sections 8.2(a)(i)-(iv) hereof, Seller and its Affiliates shall not be restricted from being, and shall be entitled to be a passive owner of not more than five percent (5%) of the outstanding securities of any class of an entity which is publicly traded, provided that Seller has no active participation in the business of such entity or any control over such entity. (d) The covenants in this Section 8.2 are severable and separate, and the unenforceability of any specific covenant in this Section 8.2 is not intended by any party hereto to, and shall not, affect the provisions of any other covenant in this Section 8.2. If any court of competent jurisdiction shall determine that the scope, time, or territorial restrictions set forth in this Section 8.2 are unreasonable and thus unenforceable, the parties hereto acknowledge their mutual intention and agreement that those restrictions be enforced to the extent necessary for the restrictions to meet the legal requirements for enforceability as determined by the court. (e) All of the covenants in this Section 8.2 are intended by each party hereto to be, and shall be construed as, an agreement independent of any other provision in this Agreement and the existence of any claim or cause of action of Seller against Purchaser, whether predicated on this Agreement or otherwise, shall not constitute a defense to the enforcement by Purchaser of any covenant in this Section 8.2. It is specifically agreed that the time periods specified in Section 8.2(a) and Section 8.2(b), including the Restricted Period and the Business Combination Restricted Period, shall be computed by excluding from that computation any time during which Seller is in material violation of any provision of Section 8.2(a) or Section 8.2(b). (f) Purchaser and Seller hereby agree that this Section 8.2 is a material and substantial part of this Agreement, and absent Seller agreeing to be bound by this Section 8.2, Purchaser would not have consummated the Acquisition. (g) Because Seller's services have been and are unique and because Seller has had access to Confidential Information, the parties hereto agree that money damages would not necessarily be an adequate remedy for any breach of this Section 8.2. Because of the difficulty in measuring the economic losses that may be incurred by Purchaser as a result of any breach by Seller of the covenants in this Section 8.2 and because of the immediate and irreparable - 28 -

damage that could be caused to Purchaser for which it would have no other adequate remedy, Seller agrees that Purchaser may enforce the provisions of this Section 8.2 by any equitable or legal means, including seeking an appropriate injunction or restraining order against Seller if a breach of any of those provisions occurs. Therefore, in the event of a breach or threatened breach of this Section 8.2, Purchaser or its successors or assigns may, in addition to other rights and remedies existing in their favor, apply to any court of competent jurisdiction for specific performance and/or injunctive or other relief (temporary and/or permanent), in order to enforce, or prevent any violations of, the provisions hereof. (h) In the event of any material breach or threatened material breach by Seller or any of its Affiliates of the terms of this Article VIII, Seller shall reimburse Purchaser for its reasonable attorneys' fees, court costs and other expenses it incurs in successfully enforcing the provisions of this Article VIII.
