The Merger Consideration, when distributed by the Exchange Agent pursuant to Section 1.10, shall be distributed as follows: (a) DISTRIBUTION OF CASH DISTRIBUTION. The Cash Distribution (other than the portion of the Cash Distribution withheld by Parent for the Assumed Option Amount and the Assumed Warrant Amount) shall be distributed ratably among the holders of the Company Common Stock in proportion to the number of shares of Company Common Stock held by each holder. The portion of the Cash Distribution withheld by Parent for the Assumed Option Amount and the Assumed Warrant Amount shall be delivered by Parent to the Exchange Agent at the same time that Parent delivers shares of Parent Common Stock, if any, issued pursuant to Section 1.6(b)(ii)(A) or (B), and such portion of the Cash Distribution shall be distributed, after the expiration of the Assumed Options and the Assumed Warrants, among the holders of Assumed Options and Assumed Warrants who timely and properly exercise their Assumed Options and Assumed Warrants so that such holders receive the portion of the Cash Distribution that they would have received had they exercised their Assumed Options and Assumed Warrants immediately prior to the Effective Time. Any portion of the Cash Distribution withheld by Parent for the Assumed Option Amount and the Assumed Warrant Amount not required to be distributed pursuant to the preceding sentence shall be added to and be distributed as part of the Designated Assets (as defined in Section 1.7(b) below). Notwithstanding anything to the contrary in this Agreement, in no event shall any holder receiving a portion of the Cash Distribution distributed pursuant to this Section 1.7(a) be required to pay any portion of such Cash Distribution to any other holder of Company Common Stock or Company Preferred Stock on account of the distribution arrangements described in Section 1.7(b) below. (b) DISTRIBUTION OF DESIGNATED ASSETS. (i) DESIGNATED ASSETS. The distribution arrangement described in this Section 1.7(b) shall apply to the following (collectively, the "Designated Assets"): (A) the Stock Consideration; (B) the cash, if any, actually received by Parent on account of the exercise of Assumed Options and Assumed Warrants; and (C) any portion of the Cash Distribution withheld by Parent for the Assumed Option Amount and the Assumed Warrant Amount not required to be distributed pursuant to Section 1.7(a) above. (ii) DISTRIBUTION PROCEDURES. The Designated Assets shall be distributed as follows: (A) First, if the amount of the Cash Distribution is less than $1,000,000, a portion of the First Payment shall be distributed ratably among the holders of the Company Common Stock. The portion of the First Payment to be distributed to the holders of Company Common Stock shall be a number of shares with a dollar value -5- equal to $1,000,000 minus the amount of the Cash Distribution, with the First Payment shares to be valued pursuant to Section 1.7(e). (B) Second, the remaining Designated Assets shall be distributed ratably among the holders of the Company Series A Preferred Stock, the Company Series B Preferred Stock and the Company Series C Preferred Stock (collectively, "Company Preferred Stock"), until each such holder has respectively received the full Series A Preference Amount, Series B Preference Amount and Series C Preference Amount (each as defined in Section 1.7(f) below) for all shares of Company Preferred Stock held by such holder. In the event that the value of the Designated Assets available for distribution under this Section 1.7(b)(ii)(B) is less than the amount that is required to satisfy in full all of the Preference Amounts (as defined in Section 1.7(f) below), the amount of the Designated Assets available for distribution under this Section 1.7(b)(ii)(B) shall be distributed ratably among the holders of the Company Preferred Stock in proportion to the Preference Amount each holder would otherwise be entitled to receive. All Stock Consideration distributed pursuant to this Section 1.7(b)(ii)(B) shall be valued pursuant to Section 1.7(e). (C) Third, any remaining Designated Assets shall be distributed ratably among the holders of the Company Common Stock and the Company Series C Preferred Stock in proportion to the number of shares of Company Common Stock held by each holder (taking into account, for purposes of calculating the amount deemed received by holders of Company Common Stock under this Section 1.7(b)(ii)(C), the portion of the Cash Distribution, if any, received at any time by the holders of the Company Common Stock as well as the amount distributed to holders of the Company Common Stock pursuant to Section 1.7(b)(ii)(A)). The parties intend that the Designated Assets shall be distributed under this Section 1.7(b)(ii)(C) so that each holder of Company Common Stock and each holder of Company Series C Preferred Stock receives an amount equal to the holder's pro rata portion (in proportion to the number of shares of Company Common Stock held or deemed held by each holder) of the sum of the Designated Assets distributed under this Section 1.7(b)(ii)(C) plus the portion of the Cash Distribution received at any time by the holders of Company Common Stock. For purposes of this Section 1.7(b)(ii)(C), each holder of the Company Series C Preferred Stock will be deemed to hold the number of shares of Company Common Stock that would have been issued to the holder had the holder converted all of his or her Company Series C Preferred Stock into Company Common Stock on the Revaluation Date (as defined in Section 1.7(b)(iii) below). (iii) REVALUATION OF DESIGNATED ASSETS. Notwithstanding any prior distribution of the Designated Assets, as of the date on which all unexercised Assumed Options and Assumed Warrants expire (the "Revaluation Date") and prior to release to any Former Company Stockholders (as defined in Section 5.17 below) of any portion of the Escrow Fund (as defined in Section 7.2(a) below), the Designated Assets shall be redistributed among the Former Company Stockholders in accordance with Section 1.7(b)(ii) based on the valuation of such Designated Assets as of the Revaluation Date. Solely for purposes of the redistribution of the Designated Assets as of the Revaluation -6- Date contemplated by this Section 1.7(b)(iii), the shares of Parent Common Stock included in such Designated Assets shall be valued at the average of the closing prices of Parent Common Stock on the Nasdaq National Market for the five (5) consecutive trading days ending five (5) trading days prior to the Revaluation Date. No revaluation or redistribution of any of the Designated Assets shall occur with respect to the Stock Consideration, if any, distributed by Parent after the Revaluation Date. In no event, however, shall the aggregate value of the Merger Consideration distributed to the holders of Company Preferred Stock be less than the aggregate value of the Merger Consideration distributed to the holders of the Company Common Stock and the holders of Assumed Options and Assumed Warrants. (c) TAX ALLOCATION OF MERGER CONSIDERATION. Solely in connection with tax matters, the Merger Consideration will be allocated among the holders of Company Common Stock and Company Preferred Stock consistent with the distribution arrangements described in Section 1.7(a) and (b) above (making the assumption that none of the First Payment is paid to Parent pursuant to Article VII). (d) CERTIFICATES OF SECURITYHOLDER AGENT; RELEASE. (i) CERTIFICATES. Not later than fifteen (15) days prior to the date that any of the Merger Consideration is to be delivered by Parent to the Exchange Agent pursuant to Section 1.10(b) for distribution to the Former Company Stockholders, the Securityholder Agent shall deliver to Parent a certificate (each, an "Agent Certificate") identifying each of the Former Company Stockholders and the portion of such Merger Consideration, if any, that each such Former Company Stockholder is entitled to receive pursuant to Section 1.7(a) and (b) above. Parent shall be entitled to rely without investigation on the information set forth in each Agent Certificate in delivering the Merger Consideration to the Exchange Agent for distribution pursuant to Section 1.10(b). Notwithstanding anything to the contrary in this Agreement, Parent shall not be obligated to deliver any portion of the Merger Consideration to the Exchange Agent unless and until the Securityholder Agent shall have delivered an Agent Certificate to Parent with respect to such portion of the Merger Consideration as required by this Section 1.7(d)(i). (ii) RELEASE. The Company, for itself, each of its Subsidiaries, all Former Company Stockholders and each of their respective officers, directors, stockholders, partners, agents, administrators, representatives, affiliates, predecessors in interest, successors and assigns, hereby unconditionally and forever releases and discharges Parent, each of its subsidiaries (including the Surviving Corporation), and each of their respective officers, directors, stockholders, partners, agents, administrators, representatives, affiliates, predecessors in interest, successors and assigns (the "Released Parties") of and from any and all claims, causes of action, liabilities, obligations, costs and expenses of every kind and nature whatsoever, at law or in equity, whether contractual, common law, statutory, federal, state or otherwise, known or unknown, suspected or unsuspected, direct or derivative, which now exists or may exist at any time in the future based upon or relating in any manner to the distribution of the Merger -7- Consideration pursuant to Section 1.7 or any dispute with respect to the interpretation of the manner in which the Merger Consideration is to be distributed pursuant to Section 1.7.

(c) EXCHANGE PROCEDURES. Promptly after the Effective Time, the Surviving Corporation shall cause to be mailed to each holder of record of a certificate or certificates (the "Certificates") which immediately prior to the Effective Time represented outstanding shares of Company Capital Stock and which shares were converted into the right to receive the portion of the Merger Consideration issuable with respect to such shares pursuant to Section 1.7, (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent and shall be in such form and have such other provisions as Parent may reasonably specify) and (ii) instructions for use in effecting the surrender of the Certificates in exchange for the Merger Consideration. Upon surrender of a Certificate for cancellation to the Exchange Agent or to such other agent or agents as may be appointed by Parent, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, the holder of such Certificate shall be entitled to receive in -13- exchange therefor the portion of the Merger Consideration issuable pursuant to Section 1.7 (less the First Payment to be deposited in the Escrow Fund on such holder's behalf pursuant to Article VII below) as and when the Exchange Agent receives the Merger Consideration with respect to the shares of Company Capital Stock represented by such Certificate, and the Certificate so surrendered shall forthwith be canceled. Subject to and in accordance with the provisions of Article VII hereof, Parent shall cause to be distributed to the Escrow Agent (as defined in Article VII) a certificate or certificates representing the number of shares of Parent Common Stock equal to the First Payment, which certificate shall be registered in the name of the Escrow Agent. Such shares shall be beneficially owned by the holders on whose behalf such shares were deposited in the Escrow Fund and shall be available to compensate Parent as provided in Article VII. Until so surrendered, each outstanding Certificate that, prior to the Effective Time, represented shares of Company Capital Stock will be deemed from and after the Effective Time, for all corporate purposes, other than the payment of dividends, to evidence the right to receive in accordance with Section 1.8(a) the portion of the Merger Consideration issuable pursuant to Section 1.7 (less the Escrow Amount to be deposited in the Escrow Fund on such holder's behalf pursuant to Article VII below) as and when the Exchange Agent receives the Merger Consideration with respect to the shares of Company Capital Stock represented by such Certificate. (d) DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED SHARES. No dividends or other distributions with respect to Parent Common Stock declared or made after the date such shares are to be distributed to the holders of the Company Capital Stock and with a record date after such date will be paid to the holder of any unsurrendered Certificate with respect to the shares of Parent Common Stock represented thereby until the holder of record of such Certificate shall surrender such Certificate. Subject to applicable law, following surrender of any such Certificate, there shall be paid to the record holder of the certificates representing whole shares of Parent Common Stock issued in exchange therefor, without interest, at the time of such surrender, the amount of dividends or other distributions with a record date after the date such shares are to be distributed to the holders of the Company Capital Stock theretofore payable with respect to such whole shares of Parent Common Stock. (e) TRANSFERS OF OWNERSHIP. If any certificate for shares of Parent Common Stock is to be issued in a name other than that in which the Certificate surrendered in exchange therefor is registered, it will be a condition of the issuance thereof that the Certificate so surrendered will be properly endorsed and otherwise in proper form for transfer and that the person requesting such exchange will have paid to Parent or any agent designated by it any transfer or other taxes required by reason of the issuance of a certificate for shares of Parent Common Stock in any name other than that of the registered holder of the Certificate surrendered, or established to the satisfaction of Parent or any agent designated by it that such tax has been paid or is not payable. (f) NO LIABILITY. Notwithstanding anything to the contrary in this Section 1.10, none of the Exchange Agent, the Surviving Corporation or any party hereto shall be liable to a holder of shares of Parent Common Stock or Company Capital Stock -14- for any amount properly paid to a public official pursuant to any applicable abandoned property, escheat or similar law. 1.11 NO FURTHER OWNERSHIP RIGHTS IN COMPANY COMMON STOCK. All shares of Parent Common Stock issued upon the surrender for exchange of shares of Company Capital Stock 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 Capital Stock, and there shall be no further registration of transfers on the records of the Surviving Corporation of shares of Company Capital Stock which were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Corporation for any reason, they shall be canceled and exchanged as provided in this Article 1. 1.12 LOST, STOLEN OR DESTROYED CERTIFICATES. In the event any Certificates evidencing shares of Company Capital Stock shall have been lost, stolen or destroyed, the Exchange Agent shall issue in exchange for such lost, stolen or destroyed Certificates, upon the making of an affidavit of that fact by the holder thereof, such shares of Parent Common Stock, if any, as may be required to be delivered in exchange therefor pursuant to Section 1.7; provided, however, that Parent may, in its discretion and as a condition precedent to the issuance thereof, require the owner of such lost, stolen or destroyed Certificates to deliver a bond in such sum as it may reasonably direct as indemnity against any claim that may be made against Parent or the Exchange Agent with respect to the Certificates alleged to have been lost, stolen or destroyed. 1.13 TAX AND ACCOUNTING CONSEQUENCES. It is intended by the parties hereto that the Merger shall be accounted for as a purchase, NOT a pooling of interests. It is also intended by the Company that the Merger shall constitute a reorganization within the meaning of Section 368 of the Internal Revenue Code of 1986, as amended (the "Code"). Each party agrees to report the Merger as a reorganization within the meaning of Section 368 of the Code unless (i) there is a final determination following an audit that the Merger does not qualify for such reporting or (ii) such party's tax advisors conclude after consultation with the other party's tax advisors that there is not substantial authority for such reporting. 1.14 TAKING OF NECESSARY ACTION; FURTHER ACTION.

The Escrow Fund shall be available to compensate Parent and its affiliates for any claims, losses, liabilities, damages, deficiencies, costs and expenses, including reasonable attorneys' fees and expenses, and expenses of investigation and defense (hereinafter individually a "Loss" and collectively "Losses") incurred by Parent, its officers, directors, or affiliates (including the Surviving Corporation) directly or indirectly as a result of (i) any inaccuracy or breach of a representation or warranty of the Company contained in Article II herein (as modified by the Company Schedules), (ii) any failure by the Company to perform or comply with any covenant contained herein, including but not limited to Section 2.23 of this Agreement, (iii) any Taxes owing by the Company or any Subsidiary, whether before or after the Closing, as a result of the activities of the Company or the Subsidiary prior to the Closing, (iv) any claim by any holder of Company Capital Stock that it did not receive the portion of the Merger Consideration to which it was entitled, (v) the Company's ownership of QBI or the operation or conduct of QBI's business, (vi) any unpaid Third Party Expenses of the Company, (vii) any claim by any person employed by the Company prior to the Effective Time arising out of the relationship of employment, the termination of employment, or any matter arising out of the person's relationship with the Company or the transactions contemplated by this Agreement, other than any rights the person may have (A) to receive a portion of the Merger Consideration as a holder of any Company Capital Stock or an Assumed Option, (B) to receive the distribution of such person's vested interest in the Avid Corporation Savings Retirement Plan, or (C) to receive the portion of the Severance Payments to which the person may be entitled, or (vii) any liability or obligation of any type, whether accrued, absolute, contingent, matured, unmatured or other, incurred by the Company or arising out of or relating to the operation of the Company's business at or prior to the Effective Time, excluding (A) all liabilities and obligations that are specified in the Company Schedules and both (1) first become due and payable after the Closing and (2) for which the goods, services or other consideration to be received by the Company in connection therewith are to be provided to the Company after the Closing, and (B) the Lead Compound Expenses (such excluded liabilities and obligations, the "Assumed Liabilities"). Parent and the Company each acknowledge that such Losses, if any, would relate to the unresolved contingencies existing at the Effective Time, which, if resolved at the Effective Time would have led to a reduction in the aggregate Merger consideration. Nothing herein shall limit the liability of the Company for any such breach of any representation, warranty or covenant if the Merger does not close. (b) DISTRIBUTIONS OF ESCROW AMOUNT. (i) In the event that neither of the conditions described in Section 1.6(b)(ii)(A) is satisfied on or prior to the date that is eighteen (18) months after the Closing Date, Parent and the Securityholder Agent shall deliver written notice to the Escrow Agent certifying that neither of such conditions has been satisfied. The Escrow Agent shall within seventy-five (75) days thereafter deliver to the stockholders of the Company the portion of the Escrow Fund, if any, in excess of 200,000 shares of Parent -57- Common Stock. Deliveries of Escrow Amounts to the stockholders of the Company pursuant to this Section 7.2(b)(i) shall be made based on their interest in such Escrow Amounts as of the Revaluation Date as certified by the Securityholder Agent in an Agent Certificate delivered to Parent and the Escrow Agent no later than fifteen (15) days prior to the date of the distribution from the Escrow Fund. The Escrow Agent shall not be obligated to deliver any Escrow Amounts to the stockholders of the Company pursuant to this Section 7.2(b)(i) unless and until the Securityholder Agent shall have delivered an Agent Certificate to Parent and the Escrow Agent with respect to such Escrow Amounts as required by this Section 7.2(b)(i). (ii) As soon as all claims specified in any Officer's Certificate delivered to the Escrow Agent prior to termination of the Escrow Period have been resolved and after the termination of the Escrow Period, the Escrow Agent shall deliver to the stockholders of the Company the remaining portion of the Escrow Fund not required to satisfy such claims. Deliveries of Escrow Amounts to the stockholders of the Company pursuant to this Section 7.2(b)(ii) shall be made based on their interest in such Escrow Amounts as of the date of distribution from the Escrow Fund as certified by the Securityholder Agent in an Agent Certificate delivered to Parent and the Escrow Agent no later than fifteen (15) days prior to the date of the distribution from the Escrow Fund. The Escrow Agent shall not be obligated to deliver any Escrow Amounts to the stockholders of the Company pursuant to this Section 7.2(b)(ii) unless and until the Securityholder Agent shall have delivered an Agent Certificate to Parent and the Escrow Agent with respect to such Escrow Amounts as required by this Section 7.2(b)(ii). (c) PROTECTION OF ESCROW FUND. (i) The Escrow Agent shall hold and safeguard the Escrow Fund during the Escrow Period, shall treat such fund as a trust fund in accordance with the terms of this Agreement and not as the property of Parent and shall hold and dispose of the Escrow Fund only in accordance with the terms hereof. (ii) Any shares of Parent Common Stock or other equity securities issued or distributed by Parent (including shares issued upon a stock split, stock dividend or recapitalization effected by Parent after the Effective Time) ("New Shares") in respect of Parent Common Stock in the Escrow Fund which have not been released from the Escrow Fund shall be added to the Escrow Fund and become a part thereof. New Shares issued in respect of shares of Parent Common Stock which have been released from the Escrow Fund shall not be added to the Escrow Fund but shall be distributed to the recordholders thereof. Cash dividends on Parent Common Stock shall not be added to the Escrow Fund but shall be distributed to the recordholders thereof. (iii) Each stockholder shall have voting rights with respect to the shares of Parent Common Stock contributed to the Escrow Fund by such stockholder (and any voting securities added to the Escrow Fund in respect of such shares of Parent Common Stock). -58- (d) CLAIMS UPON ESCROW FUND. (i) Upon receipt by the Escrow Agent at any time on or before the last day of the Escrow Period of a certificate signed by any officer of Parent (an "Officer Certificate"): (A) stating that Parent has paid or properly accrued or reasonably anticipates that it will have to pay or accrue Losses, and (B) specifying in reasonable detail the individual items of Losses included in the amount so stated, the date each such item was paid or properly accrued, or the basis for such anticipated liability, and the nature of the misrepresentation, breach of warranty or covenant to which such item is related, the Escrow Agent shall, subject to the provisions of Section 7.2(f) hereof, deliver to Parent out of the Escrow Fund, as promptly as practicable following expiration of the 30-day period specified in Section 7.2(e) or after the Escrow Agent shall have received written authorization from the Securityholder Agent to make such delivery if such authorization is given prior to the end of the 30-day period, shares of Parent Common Stock held in the Escrow Fund in an amount equal to such Losses. (ii) For purposes of determining the number of shares of Parent Common Stock to be delivered to Parent out of the Escrow Fund pursuant to Section 7.2(d)(i) hereof, the shares of Parent Common Stock shall be valued at the average of the closing prices of Parent Common Stock on the Nasdaq National Market for the five (5) consecutive trading days ending five (5) trading days prior to the Closing Date. Parent and the Securityholder Agent (as defined below) shall certify such fair market value in a certificate signed by both Parent and the Securityholder Agent, and shall deliver such certificate to the Escrow Agent. (e) OBJECTIONS OF CLAIMS. At the time of delivery of any Officer's Certificate to the Escrow Agent, a duplicate copy of such certificate shall be delivered to the Securityholder Agent and Parent shall certify to the Escrow Agent that such duplicate copy has been so delivered. For a period of thirty (30) days after such delivery, the Escrow Agent shall make no delivery to Parent of any shares of Parent Common Stock held in the Escrow Fund pursuant to Section 7.2(d) hereof unless the Escrow Agent shall have received written authorization from the Securityholder Agent to make such delivery. After the expiration of such thirty (30) day period, the Escrow Agent shall make delivery of shares of Parent Common Stock from the Escrow Fund in accordance with Section 7.2(d) hereof, provided that no such payment or delivery may be made if the Securityholder Agent shall object in a written statement to the claim made in the Officer's Certificate, and such statement shall have been delivered to the Escrow Agent prior to the expiration of such thirty (30) day period. (f) RESOLUTION OF CONFLICTS; ARBITRATION. (i) In case the Securityholder Agent shall so object in writing to any claim or claims made in any Officer's Certificate, the Securityholder Agent and Parent shall attempt in good faith to agree upon the rights of the respective parties with respect to each of such claims. If the Securityholder Agent and Parent should so agree, a memorandum setting forth such agreement shall be prepared and signed by both -59- parties and shall be furnished to the Escrow Agent. The Escrow Agent shall be entitled to rely on any such memorandum and distribute shares of Parent Common Stock form the Escrow Fund in accordance with the terms thereof. (ii) If no such agreement can be reached after good faith negotiation, either Parent or the Securityholder Agent may demand arbitration of the matter unless the amount of the damage or loss is at issue in pending litigation with a third party, in which event arbitration shall not be commenced until such amount is ascertained or both parties agree to arbitration; and in either such event the matter shall be settled by arbitration conducted by three arbitrators. Parent and the Securityholder Agent shall each select one arbitrator, and the two arbitrators so selected shall select a third arbitrator. The arbitrators shall set a limited time period and establish procedures designed to reduce the cost and time for discovery while allowing the parties an opportunity, adequate in the sole judgment of the arbitrators, to discover relevant information from the opposing parties about the subject matter of the dispute. The arbitrators shall rule upon motions to compel or limit discovery and shall have the authority to impose sanctions, including attorneys' fees and costs, to the extent as a court of competent law or equity, should the arbitrators determine that discovery was sought without substantial justification or that discovery was refused or objected to without substantial justification. The decision of a majority of the three arbitrators as to the validity and amount of any claim in such Officer's Certificate shall be binding and conclusive upon the parties to this Agreement, and notwithstanding anything in Section 7.2(f) hereof, the Escrow Agent shall be entitled to act in accordance with such decision and make or withhold payments out of the Escrow Fund in accordance therewith. Such decision shall be written and shall be supported by written findings of fact and conclusions which shall set forth the award, judgment, decree or order awarded by the arbitrators. (iii) Judgment upon any award rendered by the arbitrators may be entered in any court having jurisdiction. Any such arbitration shall be held in New York, New York under the rules then in effect of the American Arbitration Association. For purposes of this Section 7.2(f)(iii), in any arbitration hereunder in which any claim or the amount thereof stated in the Officer's Certificate is at issue, Parent shall be deemed to be the Non-Prevailing Party in the event that the arbitrators award Parent less than the sum of one-half (1/2) of the disputed amount plus any amounts not in dispute; otherwise, the stockholders of the Company as represented by the Securityholder Agent shall be deemed to be the Non-Prevailing Party. The disputed amount shall equal the difference between the amount claimed or offered in settlement by Parent and the amount claimed or offered in settlement by the Securityholder Agent prior to the initiation of the arbitration. The Non-Prevailing Party to an arbitration shall pay its own expenses, the fees of each arbitrator, the administrative costs of the arbitration and the expenses, including without limitation, the reasonable attorneys' fees and costs, incurred by the other party to the arbitration. -60- (g) SECURITY AGENT OF THE STOCKHOLDERS; POWER OF ATTORNEY. (i) In the event that the Merger is approved, effective upon such vote, and without further act of any stockholder, Forrest H. Anthony, Marcia T. Bates and Alan G. Walton shall be appointed as agents and attorneys- in-fact (collectively, the "Securityholder Agent") for each stockholder of the Company (except such stockholders, if any, as shall have perfected their appraisal or dissenters' rights under Pennsylvania Law), for and on behalf of stockholders of the Company, to give and receive notices and communication, to authorize delivery to Parent of shares of Parent Common Stock from the Escrow Fund in satisfaction of claims by Parent, to object to such deliveries, to agree to, negotiate, enter into settlements and compromises of, and demand arbitration and comply with orders of courts and awards of arbitrators with respect to such claims, and to take all actions necessary or appropriate in the judgment of the Securityholder Agent for the accomplishment of the foregoing. Such agency may be changed by the stockholders of the Company from time to time upon not less than thirty (30) days prior written notice to Parent; provided that none of the Securityholder Agent may be removed unless holders of two-thirds in interest of the Escrow Fund agree to such removal and to the identity of the substituted agent. Any vacancy in the position of the Securityholder Agent may be filled by approval of the holders of a majority in interest of the Escrow Fund. No bond shall be required of the Securityholder Agent, and the Securityholder Agent shall not receive compensation for his or her services. Notice or communications to or from the Securityholder Agent shall constitute notice to or from each of the stockholders of the Company. The Securityholder Agent shall, and are hereby authorized to, act by majority approval as to any matter, even if there are less than three (3) individuals acting as Securityholder Agent at the time the action is taken. (ii) The Securityholder Agent shall not be liable for any act done or omitted hereunder as Securityholder Agent while acting in good faith and in the exercise of reasonable judgement. The stockholders of the Company on whose behalf the Escrow Amount was contributed to the Escrow Fund shall severally indemnify the Securityholder Agent and hold the Securityholder Agent harmless against any loss, liability or expense incurred without negligence or bad faith on the part of the Securityholder Agent and arising out of or in connection with the acceptance or administration of the Securityholder Agent's duties hereunder, including the reasonable fees and expenses of any legal counsel retained by the Securityholder Agent. (h) ACTIONS OF THE SECURITYHOLDER AGENT. A decision, act, consent or instruction of the Securityholder Agent shall constitute a decision of all the stockholders for whom a portion of the Escrow Amount otherwise issuable to them are deposited in the Escrow Fund and shall be final, binding and conclusive upon each of such stockholders, and the Escrow Agent and Parent may rely upon any such decision, act, consent or instruction of the Securityholder Agent as being the decision, act, consent or instruction of each and every such stockholder of the Company. The Escrow Agent and Parent are hereby relieved from any liability to any person for any acts done by them in accordance with such decision, act, consent or instruction of the Securityholder Agent. -61- (i) THIRD-PARTY CLAIMS. In the event Parent becomes aware of a third-party claim which Parent believes may result in a demand against the Escrow Fund, Parent shall notify the Securityholder Agent of such claim, and the Securityholder Agent, as representative for the stockholders of the Company, shall be entitled, at the stockholders' expense, to participate in any defense of such claim. Parent shall have the right in its sole discretion to settle any such claim; provided, however, that except with the consent of the Securityholder Agent, no settlement of any such claim with third-party claimants shall alone be determinative of the amount of any claims against the Escrow Fund. In the event that the Securityholder Agent has consented to any such settlement, the Securityholder Agent shall have no power or authority to object under any provision of this Article VII to the amount of any claim by Parent against the Escrow Fund with respect to such settlement. (j) ESCROW AGENT'S DUTIES. (i) The Escrow Agent shall be obligated only for the performance of such duties as are specifically set forth herein, and as set forth in any additional written escrow instructions which the Escrow Agent may receive after the date of this Agreement which are signed by an officer of Parent and the Securityholder Agent, and may rely and shall be protected in relying or refraining from acting on any instruction reasonably believed to be genuine and to have been signed or presented by the proper party or parties. The Escrow Agent shall not be liable for any act done or omitted hereunder as Escrow Agent while acting in good faith and in the exercise of reasonable judgment, and any act done or omitted pursuant to the advice of counsel shall be conclusive evidence of such good faith. (ii) The Escrow Agent is hereby expressly authorized to comply with and obey orders, judgments or decrees of any court of law, notwithstanding any notices, warning or other communications form any party or any other person to the contrary. In case the Escrow Agent obeys or complies with any such order, judgment or decree of any court, the Escrow Agent shall not be liable to any of the parties hereto or to any other person by reason of such compliance, notwithstanding any such order, judgment or decree being subsequently reversed, modified, annulled, set aside, vacated or found to have been entered without justification. (iii) The Escrow Agent shall not be liable in any respect on account of the identity, authority or rights of the parties executing or delivering or purporting to execute or deliver this Agreement or any documents or papers deposited or called for hereunder. (iv) The Escrow Agent shall not be liable for the expiration of any rights under any statute of limitations with respect to this Agreement or any documents deposited with the Escrow Agent. (v) In performing any duties under the Agreement, the Escrow Agent shall not be liable to any party for damages, losses, or expenses, except for gross -62- negligence or willful misconduct on the part of the Escrow Agent. The Escrow Agent shall not incur any such liability for (A) any act or failure to act made or omitted in good faith, or (B) any action taken or omitted in reliance upon any instrument, including any written statement or affidavit provided for in this Agreement that the Escrow Agent shall in good faith believe to be genuine, nor will the Escrow Agent be liable or responsible for forgeries, fraud, impersonations, or determining the scope of any representative authority. In addition, the Escrow Agent may consult with legal counsel in connection with Escrow Agent's duties under this Agreement and shall be fully protected in any act taken, suffered, or permitted by it in good faith in accordance with the advice of counsel. The Escrow Agent is not responsible for determining and verifying the authority of any person acting or purporting to act on behalf of any party to this Agreement. (vi) If any controversy arises between the parties to this Agreement, or with any other party, concerning the subject matter of this Agreement, its terms or conditions, the Escrow Agent will not be required to determine the controversy or to take any action regarding it. The Escrow Agent may hold all documents and shares of Parent Common Stock and may wait for settlement of any such controversy by final appropriate legal proceedings or other means as, in the Escrow Agent's discretion, the Escrow Agent may be required, despite what may be set forth elsewhere in this Agreement. In such event, the Escrow Agent will not be liable for damage. Furthermore, the Escrow Agent may at its option, file an action of interpleader requiring the parties to answer and litigate any claims and rights among themselves. The Escrow Agent is authorized to deposit with the clerk of the court all documents and shares of Parent Common Stock held in the Escrow Fund except all cost, expenses, charges and reasonable attorneys' fees incurred by the Escrow Agent due to the interpleader action and which the parties jointly and severally agree to pay. Upon initiating such action, the Escrow Agent shall be fully released and discharged of and from all obligations and liability imposed by the terms of this Agreement. (vii) The parties and their respective successors and assigns agree jointly and severally to indemnify and hold the Escrow Agent harmless against all losses, claims, damages, liabilities, and expenses, including reasonable costs of investigation, counsel fees, and disbursements that may be imposed on Escrow Agent or incurred by Escrow Agent in connection with the performance of his or her duties under this Agreement, including but not limited to any litigation arising from this Agreement or involving its subject matter. (viii) The Escrow Agent may resign at any time upon giving at least thirty (30) days written notice to the parties; provided, however, that no such resignation shall become effective until the appointment of a successor escrow agent which shall be accomplished as follows: the parties shall use their best efforts to mutually agree on a successor escrow agent within thirty (30) days after receiving such notice. If the parties fail to agree upon a successor escrow agent within such time, the Escrow Agent shall have the right to appoint a successor escrow agent authorized to do business in the State of North Carolina. The successor escrow agent shall execute and -63- deliver an instrument accepting such appointment and it shall, without further acts, be vested with all the estates, properties, rights, powers, and duties of the predecessor escrow agent as if originally named as escrow agent. The Escrow Agent shall be discharged from any further duties and liability under this Agreement. (k) FEES. All fees of the Escrow Agent for performance of its duties hereunder shall be paid by Parent. It is understood that the fees and usual charges agreed upon for services of the Escrow Agent shall be considered compensation for ordinary services as contemplated by this Agreement. In the event that the conditions of this Agreement are not promptly fulfilled, or if the Escrow Agent renders any service not provided for in this Agreement, or if the parties request a substantial modification of its terms, or if any controversy arises, or if the Escrow Agent is made a party to, or intervenes in, any litigation pertaining to this escrow or its subject matter, the Escrow Agent shall be reasonably compensated for such extraordinary services and reimbursed for all costs, attorney's fees, and expenses occasioned by such default, delay, controversy or litigation. Parent promises to pay these sums upon demand. ARTICLE VIII TERMINATION, AMENDMENT AND WAIVER 8.1 TERMINATION. Except as provided in Section 8.2 below, this Agreement may be terminated and the Merger abandoned at any time prior to the Effective Time: (a) by mutual written consent of the Company and Parent; (b) by Parent or the Company if: (i) the Effective Time has not occurred before 5:00 p.m. (Eastern Daylight Savings Time) on August 29, 1997 (provided that the right to terminate this Agreement under this clause 8.1(b)(i) shall not be available to pay any party whose willful failure to fulfill any obligation hereunder has been the cause of, or resulted in, the failure of the Effective Time to occur on or before such date); (ii) there shall be a final nonappealable order of a federal or state court in effect preventing consummation of the Merger; or (iii) there shall be any statute, rule, regulation or order enacted, promulgated or issued or deemed applicable to the Merger by any governmental entity that would make consummation of the Merger illegal; (c) by Parent if there shall be any action taken, or any statute, rule, regulation or order enacted, promulgated or issued or deemed applicable to the Merger, by any governmental entity, which would: (i) prohibit Parent's or the Company's ownership or operation of all or any portion of the business of the Company or (ii) compel Parent or the Company to dispose of or hold separate all or a portion of the business or assets of the Company or Parent as a result of the Merger; (d) by Parent if it is not in material breach of its obligations under this Agreement and there has been a material breach of representation, warranty, covenant -64- or agreement contained in this Agreement on the part of the Company and (i) such breach has not been cured within five (5) business days after written notice to the Company (provided that, no cure period shall be required for a breach which by its nature cannot be cured), and (ii) as a result of such breach the conditions set forth in Section 6.3(a) or 6.3(b), as the case may be, would not then be satisfied; (e) by the Company if it is not in material breach of its obligations under this Agreement and there has been a material breach of any representation, warranty, covenant or agreement contained in this Agreement on the part of the Parent or Merger Sub and (i) such breach has not been cured within. five (5) business days after written notice to Parent (provided that, no cure period shall be required for a breach which by its nature cannot be cured), and (ii) as a result of such breach the conditions set forth in Section 6.2(a) or 6.2(b), as the case may be, would not then be satisfied.
