7.3 No Conflicts. The execution and delivery of this Agreement and the Purchaser Collateral Documents by Purchaser does not, and the performance by Purchaser of the transactions contemplated by this Agreement and the Purchaser Collateral Documents will not, conflict with, or result in any violation of, or constitute a default under (a) any provision of the Certificate of Incorporation or Bylaws of Purchaser or (b) any Law or Order applicable to or binding on Purchaser.

POST-CLOSING COVENANTS

8.1 Covenant Not to Compete; Non Solicitation.

(a) Seller agrees that prior to the fourth anniversary of the Closing Date, except (i) pursuant to any Retained License Agreement, (ii) in accordance with the terms of the Software License Agreement, or (iii) or with respect to any Software that is licensed to Seller by a third party and is embedded in any of Seller's products, Seller will not, directly or indirectly, own, manage, operate, control or participate in the ownership, management, operation or control of any business, whether in corporate, proprietorship or partnership form or otherwise, engaged in the development, design, manufacturing, marketing or sale of voice enhancement and echo cancellation Software having substantially the same performance characteristics and functionality as the Software Products; provided, however, that nothing herein shall preclude Seller from owning an equity interest of five percent or less of any publicly traded company listed on a national stock exchange or on the Nasdaq National Market.

(b) Until the Fourth Anniversary, Seller will not directly or indirectly solicit, offer employment to or hire any Transferred Employee (i) who is still an employee of Purchaser, or (ii) who has, without the consent of Purchaser, terminated his or her employment with Purchaser within 180 days of such solicitation, offer or hire; provided, however, that the foregoing provision will not prevent Seller from soliciting the employment of any person pursuant to a general advertisement or similar notice.

8.2 Confidentiality. Except (a) as required by the Retained License Agreements and all other Contracts to which Seller is bound involving a license of the Software Products to a third party, and (b) as permitted pursuant to the terms of the Software License Agreement, the Joint Marketing Agreement or the Subcontractor Agreement, each party agrees that from and after the Closing, it will not, directly or indirectly, disclose, reveal, divulge or communicate to any person or entity other than its authorized officers, directors and employees, or use or otherwise exploit for its own benefit or for the benefit of anyone other than the other party, any Non-Public Information (as defined below). Neither party shall have any obligation to keep confidential any Non-Public Information if and to the extent disclosure thereof is specifically required by Law or in the enforcement of its rights hereunder; provided, however, that in the event disclosure is required by applicable Law, the disclosing party shall, to the extent reasonably possible, provide the other party with prompt notice of such requirement prior to making any disclosure so that the other party may seek an appropriate protective order. For purposes of this Section 8.2 only, "Non-Public Information" shall mean any Confidential Information that, with respect to Seller, relates to Seller's business other than the Software Business, and, with respect to Purchaser, relates to Purchaser's business (including, without limitation, the Software Business). The term Non-Public Information does not include, and there shall be no obligation hereunder with respect to, information that (i) is generally available to the public on the date of this Agreement, (ii) becomes generally available to the public other than as a result of a disclosure by a party not otherwise permissible hereunder, or (iii) a party learns from other sources and such sources have not violated their confidentiality obligation to the other party.

8.3 Specific Performance; Reformation. The parties hereto specifically acknowledge and agree that the remedy at law for any breach of Section 8.1 or 8.2 will be inadequate and that Purchaser, in addition to any other relief available to it, shall be entitled to temporary and permanent injunctive relief without the necessity of proving actual damage or posting any bond whatsoever. In the event that the provisions of Section 8.1 or 8.2 should ever be deemed to exceed the limitations provided by applicable Law, then the parties hereto agree that such provisions shall be reformed to set forth the maximum limitations permitted.

8.4 Retained License Agreements.

(a) Seller agrees that, subject to Section 8.4(c) and the terms of the Subcontractor Agreement, from and after the Closing Date, Seller (i) shall be solely responsible for all of Seller's liabilities and the performance of all of Seller's obligations under the Retained License Agreements for the benefit of Purchaser, (ii) shall not amend, modify, extend or waive any term of any Retained License Agreement without Purchaser's prior written consent, which consent shall not be unreasonably withheld, (iii) will give notice of termination with respect to each of the Retained License Agreements in accordance with the terms thereof in a form, and at such time, as reasonably requested by Purchaser, (iv) at Purchaser's request and expense (provided that, unless previously authorized in writing by Purchaser, the expenses to be borne by Purchaser shall not exceed $5,000 per assignment), assign to Purchaser or, in the event that such assignment shall require the consent of a third party, use its commercially reasonable efforts to obtain such consent to the assignment of, any Retained License Agreement (it being understood that Seller shall have no obligation pursuant to this Section 8.4(a) or otherwise to make any payment or incur any out-of-pocket expenses to obtain such consents), and (v) will, at Purchaser's sole cost and expense, (x) maintain, and upon Purchaser's request, exercise for the benefit of Purchaser, any audit rights contained in any Retained License Agreement or under applicable law to verify the amount, and validity, of any Royalty Payments due and owing to Purchaser under such Retained License Agreement, (y) provide to Purchaser the results of such audit, and (z) to the extent any such audit discloses discrepancies with the amounts paid or owing to Purchaser, cooperate and assist Purchaser in any actions, suits, proceedings, demands, assessments, judgments or compromises (collectively, "Actions") necessary for enforcing and securing the proper Royalty Payments due to Purchaser under such Retained License Agreement; provided, however, if any such Action would cause Seller to prosecute a claim against any Person that is a material customer of, or a material supplier to, Seller, the parties will cooperate with each other to determine a commercially reasonable course of action which may include the assignment to Purchaser of the applicable Retained License Agreement.

(b) Notwithstanding anything to the contrary contained herein, in the event that any audit conducted pursuant to clause (iv) in Section 8.4(a) results in the payment to Seller of any Royalty Payments (whether related to shipments made prior to, or subsequent to, the Closing Date), Seller shall pay to Purchaser all such Royalty Payments promptly upon the receipt thereof.

(c) Purchaser agrees that, from and after the Closing Date and until the termination of the applicable Retained License Agreement, Purchaser will, at its own expense, perform the support and maintenance obligations of Seller set forth in the Subcontractor Agreement.

8.5 Further Cooperation. Seller will cooperate with Purchaser, upon Purchaser's reasonable request and at Purchaser's expense, in any Actions necessary for the protection, enforcement or transfer of the Royalty Payments to Purchaser or of Purchaser's exclusive ownership rights in any the Transferred Assets.

8.6 Maintenance of Books and Records. Each of Seller and Purchaser shall preserve until the fourth anniversary of the Closing Date all records possessed by such party relating primarily to the Transferred Assets or the operation of the Software Business prior to the Closing Date. After the Closing Date, where there is a legitimate purpose, such party shall provide the other party with reasonable access, upon prior reasonable written request specifying the need therefor, during regular business hours, to (i) the relevant officers and employees of such party and (ii) the books of account and records of such party, but, in each case, only to the extent primarily relating to the Transferred Assets or the operation of the Software Business prior to the Closing Date, and the other party and its representatives shall have the right to make copies of such books and records; provided, however, that the foregoing right of access shall not be exercisable in such a manner as to interfere unreasonably with the normal operations and business of such party; and further provided that, to the extent such

information constitutes trade secrets or confidential information of such party, the requesting party will not, and shall ensure that its representatives are bound not to disclose such information except (i) as required by Law, (ii) with the prior written consent of such party, which consent shall not be unreasonably withheld, or (iii) where such information becomes available to the public generally, or becomes generally known to competitors of such party, through sources other than the requesting party and its representatives. Such records may nevertheless be destroyed by a party if such party sends the other party written notice of its intent to destroy records, specifying with particularity the contents of the records to be destroyed. Such records may then be destroyed after the 30th day following delivery of such notice unless the other party objects to the destruction, in which case the party seeking to destroy the records shall either agree to retain such records or to deliver such records to the objecting party.

8.7 Transferred Employees.

(a) Employment. Purchaser shall offer employment to each Software Business Employee on an "at will" basis on or prior to the date hereof, and the individuals who accept such offer shall be referred to as the "Transferred Employees." Each such offer of employment shall be at the same salary or hourly wage rate and position as set forth on Schedule 6.13 of the Disclosure Schedule. Subject to applicable Laws, Purchaser shall have the right to dismiss any or all Transferred Employees at any time, with or without cause, and to change the terms and conditions of their employment (including compensation and employee benefits provided to them).

(b) Past Service Credit. Purchaser agrees that, with respect to all of its employee benefit plans (except for Purchaser's retiree medical plan) covering or otherwise benefiting any of the Transferred Employees on or after the Closing Date, service with Seller as reflected on Schedule 6.13 of the Disclosure Schedule under the heading "date of hire" shall be counted solely for purposes of eligibility to participate or vesting to the same extent such service was counted under the corresponding Benefit Plans, and shall not be counted for benefit accrual purposes; provided, however, service credit with Seller as reflected on Schedule 6.13 of the Disclosure Schedule under the heading "service credit" shall be counted by Purchaser for purposes of eligibility and benefit accrual purposes for PTO to the same extent such service was counted under Seller's PTO.

(c) Paid Time Off. Except to the extent required by applicable Law, Seller shall not pay Transferred Employees their accrued and unused PTO, and Purchaser shall (i) assume all such obligations for accrued and unused PTO for each Transferred Employee, and (ii) provide, without duplication of benefits, all Transferred Employees with PTO time rather than cash in lieu of vacation time for all accrued and unused PTO through the Closing Date, but only to the extent reflected on Schedule 6.13 of the Disclosure Schedule.

(d) Benefit Plans. Purchaser shall take all actions necessary or appropriate to extend coverage as of the Closing Date to the Transferred Employees under the benefit plans maintained by Purchaser and shall ensure uninterrupted coverage of all Transferred Employees under such benefit plans. The Transferred Employees shall get credit under such benefit plans for amounts paid under the corresponding Benefit Plans by Transferred Employees during the applicable plan year preceding the Closing Date, and such benefit plans shall not exclude pre-existing conditions. Seller shall be exclusively responsible for complying with Part 6, Subtitle B, Title I of ERISA and Section 4980B of the Code ("COBRA Rights") with respect to all of Seller's employees (excluding the Transferred Employees) and their eligible dependents by reason of such employees' termination of employment with Seller, and Purchaser shall not have any obligation or liability to provide COBRA Rights on account of any such termination of employment. Purchaser shall be exclusively responsible for all COBRA Rights for all of the Transferred Employees.

(e) Seller Stock Options. Seller shall extend the exercise period of all vested options held by the Transferred Employees to one year following the termination of employment with Seller. Seller will not take any action to accelerate the vesting of any unvested Seller stock options held by such Transferred Employees, and all such unvested Seller options will terminate in accordance with their terms.

8.8 Further Cooperation. In the event that an asset of Seller that the parties did not intend to be transferred to Purchaser was transferred to Purchaser in error, Purchaser agrees to execute and deliver, or cause to be executed and delivered, all such documents and instruments and take such other actions as may be reasonably necessary to transfer all right, title and interest in such asset back to Seller. In the event that an asset of Seller should have been included as a part of the Transferred Assets transferred to Purchaser, Seller agrees to execute and deliver, or cause to be executed and delivered, all such documents and instruments and take such other actions as may be reasonably necessary to transfer all right, title and interest in such asset to Purchaser. In the event that a dispute arises between Seller and Purchaser with respect to whether a particular asset should or should not have been transferred to Purchaser, the parties agree to use reasonable efforts to resolve such dispute in a timely and mutually acceptable manner.

(a) For purposes of this Agreement, (i) "Indemnity Payment" means any amount of Indemnifiable Losses required to be paid pursuant to this Agreement, (ii) "Indemnitee" means any person or entity entitled to indemnification under this Agreement, (iii) "Indemnifying Party" means any person or entity required to provide indemnification under this Agreement, (iv) "Indemnifiable Losses" means any and all damages, losses, liabilities, obligations, costs and expenses suffered or incurred by an Indemnitee, and any and all claims, demands or suits brought against an Indemnitee (by any person or entity, including, without limitation, any Governmental Authority), including, without limitation, the costs and expenses of any and all actions, suits, proceedings, demands, assessments, judgments, settlements and compromises relating thereto and including reasonable attorneys' fees and expenses incurred by the Indemnitee in connection therewith and (v) "Third Party Claim" means any claim, action or proceeding made or brought by any Person other than a party to this Agreement (or an Affiliate thereof).

(b) Notwithstanding any other provision hereof or of any applicable law, (i) the maximum aggregate indemnification obligations of an Indemnifying Party arising from breaches of representations or warranties (other than those contained in Sections 6.4(b), and 6.8(c)) and asserted pursuant to Section 9.3(a)(i) or Section 9.3(b)(i), as applicable, shall be limited to, and

shall in no event exceed, U.S. $3,000,000, (ii) the maximum aggregate indemnification obligations of Seller arising from breaches of the representations or warranties contained in Sections 6.4(b) and 6.8(c) and asserted pursuant to Section 9.3(a)(i), as applicable, shall be limited to, and shall in no event exceed (A) the amount of the Purchase Price if a Claim Notice relating to any such breach is delivered by Purchaser to Seller on or before the date that is three (3) years following the Closing Date (the "Interim Date"); provided, however, if a Claim Notice relating to any such breach is delivered by Purchaser to Seller on or after December 8, 2003 and such breach relates to, results from or arises out of any event or circumstance that occurred prior February 1, 2000 and with respect to which (x) any of ▇▇▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇▇▇ or ▇▇▇▇▇▇▇ ▇▇▇▇▇ had any actual knowledge prior to February 1, 2000, and (y) neither ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇▇▇▇ nor ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇ have any actual knowledge as of the date hereof, then the maximum aggregate indemnification obligations of Seller related thereto shall be limited to, and shall in no event exceed, $10,000,000, or (B) $10,000,000 if a Claim Notice relating to any such breach is delivered by Purchaser to Seller during the period (the "Interim Period") between the Interim Date and the Title Warranty Termination Date (an "Interim Notice"), provided that, with respect to any claims for indemnification (X) relating to a breach of Sections 6.4(b) or 6.8(c), (Y) that are set forth in an Interim Notice, and (Z) for Indemnifiable Losses in excess of $10,000,000 in the aggregate (an "Excess Claim"), to the extent that Seller recovers any amounts from the seller parties under the Seller Acquisition Agreements, Seller additionally agrees to pay and transfer to Purchaser the lesser of (I) the amount by which such Indemnifiable Losses exceed $10,000,000, and (II) fifty percent (50%) of any amounts (whether in cash or other property) so recovered, and (iii) the maximum aggregate indemnification obligations of Seller arising from breaches of the representations and warranties contained in Article 6 shall be limited to, and shall in no event exceed, the amount of the Purchase Price (each an "Indemnification Cap"). In the event that an Indemnitee assumes the defense of a Third Party Claim, each applicable Indemnification Cap shall be deemed to be automatically reduced by the amount of any Action Expenses incurred by an Indemnifying Party on its own behalf in connection with its participation in the defense of such Third Party Claim.

(c) Notwithstanding anything to the contrary contained in this Agreement, an Indemnifying Party shall not be required to make any Indemnification Payment pursuant to Section 9.3 pursuant to any indemnification obligation under this Agreement until such time as the total amount of all Indemnifiable Losses that have been suffered or incurred by the Indemnitee exceeds $100,000 in the aggregate; provided, however, that if the total amount of such Indemnifiable Losses exceeds $100,000 in the aggregate, the Indemnitee shall be entitled to be indemnified against the entire amount of such Indemnifiable Losses, and not merely the portion of such Indemnifiable Losses exceeding $100,000.

9.3 Indemnification.

(a) Subject to Sections 9.1, 9.2, 9.5 and Article 10, from and after the Closing Date, Seller agrees to indemnify, defend and hold harmless Purchaser from and against any and all Indemnifiable Losses relating to, resulting from or arising out of:

(i) any breach of the representations and warranties of Seller contained in Article 6 of this Agreement (it being acknowledged and agreed by the parties that any disclosure or item on any schedule relating to a representation and warranty contained in Article 6 that is accompanied by the words "For information purposes only" or a similar phrase shall not, for purposes of indemnification, be deemed to qualify, or serve as an exception to, the representation or warranty to which such schedule relates);

(ii) any nonfulfillment of any covenant on the part of Seller under the terms of this Agreement;

(iii) any Retained Liabilities;

(iv) any failure to comply with any "bulk sales" laws applicable to the transactions contemplated hereby; and

(v) the use or ownership of any of the Transferred Assets prior to or on the Closing Date (other than the Assumed Liabilities).

(b) Subject to Sections 9.1, 9.2 and 9.5, from and after the Closing Date, Purchaser agrees to indemnify, defend and hold harmless Seller from and against any and all Indemnifiable Losses relating to, resulting from or arising out of:

(i) any breach of the representations and warranties of Purchaser contained in Article 7 of this Agreement;

(ii) any nonfulfillment of any covenant on the part of Purchaser under the terms of this Agreement;

(iii) any Assumed Liabilities; and

(iv) the use or ownership of any of the Transferred Assets after the Closing Date.

9.4 Defense of Third Party Claims.

(a) If any Indemnitee receives notice of assertion or commencement of any Third Party Claim against such Indemnitee with respect to which an Indemnifying Party is obligated to provide indemnification under this Agreement, the Indemnitee will give such Indemnifying Party reasonably prompt written notice thereof, but in any event not later than 30 calendar days after receipt of such notice of such Third Party Claim. Such notice will describe the Third Party Claim in reasonable detail, will include copies of all material written evidence thereof available after diligent search and attempt to locate the same and will indicate the estimated amount, if reasonably practicable, of the Indemnifiable Loss that has been or may be sustained by the Indemnitee. The Indemnifying Party will have the right to participate in, or, by giving written notice to the Indemnitee, to assume, the defense of any Third Party Claim at such Indemnifying Party's own expense and by such Indemnifying Party's own counsel (reasonably satisfactory to the Indemnitee), and the Indemnitee will cooperate in good faith in such defense.

(b) If, within 30 calendar days after giving notice of a Third Party Claim to an Indemnifying Party pursuant to Section 9.4(a), an Indemnitee receives written notice from the Indemnifying Party that the Indemnifying Party has elected to assume the defense of such Third Party Claim as provided in the last sentence of Section 9.4(a), the Indemnifying Party will not be liable for any legal expenses subsequently incurred by the Indemnitee in connection with the defense thereof; provided, however, that if the Indemnifying Party fails to take reasonable steps necessary to defend diligently such Third Party Claim within 30 calendar days after receiving written notice from the Indemnitee that the Indemnitee reasonably believes the Indemnifying Party has failed to take such steps or if the Indemnifying Party has not undertaken fully to indemnify the Indemnitee in respect of all Indemnifiable Losses (without regard to any applicable Indemnification Cap) relating to the matter, the Indemnitee may assume its own defense, and the Indemnifying Party will be liable for all reasonable costs and expenses paid or incurred in connection therewith. If the Indemnitee assumes the defense of the Third Party Claim, the Indemnitee shall not enter into any settlement of such claim, or admit any liability on the part of Seller with respect to such claim, without the prior written consent of the Indemnifying Party, which consent shall not be unreasonably withheld or delayed; provided, however, if the Indemnitee provides written notice to the Indemnifying Party that it relinquishes any and all claims for indemnification pursuant to Articles 9 or 10 in respect of such Third Party Claim, Indemnitee may freely enter into any settlement agreement without the prior written consent of the Indemnifying Party. Without the prior written consent of the

Indemnitee (which consent shall not be unreasonably withheld or delayed), the Indemnifying Party will not enter into any settlement of any Third Party Claim that would lead to liability or create any financial or other obligation on the part of the Indemnitee for which the Indemnitee is not entitled to indemnification hereunder. If (i) a firm offer is made to settle a Third Party Claim without leading to liability, or the creation of a financial or other obligation on the part of the Indemnitee, and (ii) the Indemnifying Party desires to accept and agree to such offer, the Indemnifying Party will give written notice to the Indemnitee to that effect. If the Indemnitee fails to consent to such firm offer within 5 Business Days after its receipt of such notice, the Indemnitee may continue to contest or defend such Third Party Claim. In any event, the maximum liability of the Indemnifying Party as to any Third Party Claim will not exceed the amount of such settlement offer, plus costs and expenses paid or incurred by the Indemnitee through the end of such 5 Business Day period.

(c) A failure to give timely notice or to include any specified information in any notice as provided in Sections 9.4(a) or 9.4(b) will not affect the rights or obligations of any party hereunder except and only to the extent that, as a result of such failure, any party that was entitled to receive such notice was deprived of its right to recover any payment under its applicable insurance coverage or was otherwise materially damaged as a result of such failure.

9.5 Claims.

(a) If any Indemnitee has, or claims to have, incurred or suffered Indemnifiable Losses for which it is, or may be, entitled to indemnification under this Section 9, such Indemnitee, acting in good faith, may deliver a claim notice (a "Claim Notice") to the Indemnifying Party. Each Claim Notice shall (i) state that such Indemnitee believes that there is or has been a breach of a representation, warranty or covenant contained in this Agreement or that such Indemnitee is otherwise entitled to indemnification under this Section 9, (ii) contain a brief description of the circumstances supporting such Indemnitee's belief that there is or has been such a breach or that such Indemnitee is so entitled to indemnification, and (iii) to the extent possible, contain a good faith, non-binding, preliminary estimate of the amount of Indemnifiable Losses such Indemnitee claims to have so incurred or suffered or will incur or suffer (the "Claimed Amount"), or a statement that such Indemnifiable Losses are not capable of being estimated or quantified at such time and that the Claim Notice will be amended to include a Claimed Amount at a later date. In the event that a Claim Notice contains a statement that the amount of the Indemnifiable Losses are not capable of being estimated or quantified at the time that the Claim Notice is delivered (a "Silent Claim Notice"), the Indemnitee shall, at such time as such Indemnifiable Losses are capable of being estimated or quantified promptly deliver to the Indemnifying Party an amended Claim Notice setting forth the Claimed Amount (the "Complete Claim Notice"). In the event that (x) an Indemnitee incurs or suffers additional Indemnifiable Losses subsequent to the date on which a Claim Notice (the "Original Claim Notice") had previously been sent resulting from the same fact or circumstances set forth in such Claim Notice, or (y) the Original Claim Notice did not otherwise accurately state the amount of Indemnifiable Losses incurred or suffered by the Indemnitee, then the Indemnitee will deliver to the Indemnifying Party an additional Claim Notice setting forth the amount of Indemnifiable Losses that were not included in the Original Claim Notice (an "Additional Claim Notice"). For the purposes of Section 9.1(a), a Complete Claim Notice shall be deemed to have been delivered to the Indemnifying Party on the date that the Silent Claim Notice was delivered and an Additional Claim Notice shall be deemed to have been delivered to the Indemnifying Party on the date that the Original Claim Notice was delivered.

(b) Within thirty (30) days after receipt by the Indemnifying Party of a Claim Notice (other than a Silent Claim Notice) (the "Dispute Period"), the Indemnifying Party may deliver to the Indemnitee who delivered such Claim Notice a written response (the "Response Notice") in which the Indemnifying Party: (i) agrees that the full Claimed Amount is owed to the Indemnitee;

(ii) agrees that part, but not all, of the Claimed Amount (the "Agreed Amount") is owed to the Indemnitee; or (iii) indicates that no part of the Claimed Amount is owing to the Indemnitee. Any part of the Claimed Amount that is not agreed to be owing to the Indemnitee pursuant to the Response Notice shall be the "Contested Amount." If a Response Notice is not received by the Indemnitee in respect of a Claim Notice (other than a Silent Claim Notice) prior to the expiration of the Dispute Period, then the Indemnifying Party shall be conclusively deemed to have agreed that the full Claimed Amount is owed to the Indemnitee.

(c) If (i) the Indemnifying Party delivers a Response Notice agreeing that the full Claimed Amount is owed to the Indemnitee, or (ii) the Indemnifying Party does not deliver a Response Notice on a timely basis in accordance with Section 9.5(b), then the Indemnifying Party shall, within ten (10) Business Days following the receipt of such Response Notice (or if the Indemnitee has not received a Response Notice, within ten (10) Business Days following the expiration of the Dispute Period referred to in Section 9.5(b)), subject to the limitations set forth in Section 9.2(b), pay the Claimed Amount to the Indemnitee; provided, however, that in the event Seller is the Indemnifying Party, the Claimed Amount is based upon a breach of a representation or warranty of Seller set forth in Article 6 and the Claimed Amount relates to a Claim Notice delivered to Seller prior to the First Anniversary, Seller shall have no obligation to pay the Claimed Amount and such amount shall, subject to the limitations set forth in Section 9.2(b), be deducted from the Conditional Payment; provided, further, if the Claimed Amount is based upon a breach of the representations and warranties contained in either Section 6.4(b) or Section 6.8(c) and the Conditional Payment is less than the Claimed Amount Seller shall, within ten (10) Business Days following the delivery of the Response Notice, subject to the limitations set forth in Section 9.2(b), pay the difference thereof to Purchaser; provided, further, if the Claimed Amount is based upon a breach of the representations and warranties contained in either Section 6.4(b) or Section 6.8(c) and such claim is made after the First Anniversary Seller shall, within ten (10) Business Days following the delivery of the Response Notice, subject to the limitations set forth in Section 9.2(b), pay the Claimed Amount to Purchaser.

(d) If the Indemnifying Party delivers a Response Notice agreeing that less than the full Claimed Amount is owed to the Indemnitee, the Indemnifying Party shall, within ten (10) Business Days following the delivery of such Response Notice, pay the Agreed Amount to such Indemnitee; provided, however, that in the event Seller is the Indemnifying Party, the Agreed Amount is based upon a breach of a representation or warranty of Seller set forth in Article 6 and the Agreed Amount relates to a Claim Notice delivered to Seller prior to the First Anniversary, Seller shall have no obligation to pay the Agreed Amount to Purchaser and such amount shall, subject to the limitations set forth in Section 9.2(b), be deducted from the Conditional Payment; provided, further, if the Agreed Amount is based upon a breach of the representations and warranties contained in either Section 6.4(b) or Section 6.8(c) and the Conditional Payment is less than the Agreed Amount, Seller shall, within ten (10) Business Days following the delivery of the Response Notice, subject to the limitations set forth in Section 9.2(b), pay the difference thereof to Purchaser; provided, further, if the Agreed Amount is based upon a breach of the representations and warranties contained in either Section 6.4(b) or Section 6.8(c) and such claim is made after the First Anniversary Seller shall, within ten (10) Business Days following the delivery of the Response Notice, subject to the limitations set forth in Section 9.2(b), pay the Agreed Amount to Purchaser.

(e) If the Indemnifying Party delivers a Response Notice indicating that there is a Contested Amount, the Indemnifying Party and the Indemnitee shall attempt in good faith to resolve the dispute related to the Contested Amount. In the event that the parties are unable to resolve such dispute, the Indemnitee will be free to pursue such remedies as are available under this Agreement, at law or in equity in respect of such claim for indemnification. If the Indemnitee and the Indemnifying Party resolve such dispute, such resolution shall be binding on the Indemnifying

Party and the Indemnitee if signed in writing by such parties. The Indemnifying Party shall, within ten (10) business days following the date of execution of such written instrument, or such shorter period as the parties may agree, subject to the limitations set forth in Section 9.2(b), pay the amount specified in such written instrument to the Indemnitee; provided, however, that in the event Seller is the Indemnifying Party, such claim is based upon a breach of a representation or warranty of Seller set forth in Article 6 and such claim relates to a Claim Notice delivered to Seller prior to the First Anniversary, Seller shall have no obligation to pay such amount to Purchaser and such amount shall, subject to the limitations set forth in Section 9.2(b), be deducted from the Conditional Payment; provided, further, if such claim is based upon a breach of the representations and warranties contained in either Section 6.4(b) or Section 6.8(c) and the Conditional Payment is less than the amount agreed to by the parties Seller shall, within ten (10) Business Days following the date of execution of such written instrument, subject to the limitations set forth in Section 9.2(b), pay the difference thereof to Purchaser; provided, further, if such claim is based upon a breach of the representations and warranties contained in either Section 6.4(b) or Section 6.8(c) and is made after the First Anniversary Seller shall, within ten (10) Business Days following the date of execution of such written instrument, subject to the limitations set forth in Section 9.2(b), pay the amount agreed to by the parties to Purchaser.

9.6 Exclusive Remedy; Adjustment to Purchase Price.

(a) To the extent permitted by Law, the indemnity provisions of this Article 9 and Article 10 shall be the sole and exclusive remedy of the parties with respect to any breach of the representations, warranties and covenants contained in this Agreement and the other indemnification obligations set forth in Section 9.3 that are asserted subsequent to Closing, provided, however, that the foregoing shall not prohibit any party from seeking an injunction or other equitable remedy in respect thereof.

(b) Any (i) reduction of the Conditional Payment or (ii) other payments by Seller to Purchaser pursuant to Article 9 or Article 10 shall be treated as an adjustment to the purchase price of the Transferred Assets.

ARTICLE 10

CONDITIONAL PAYMENT

10.1 Payment of Conditional Payment. Subject to Section 10.2, on the First Anniversary, Purchaser shall pay to Seller by wire transfer of immediately available funds to an account previously designated by Seller an amount, if greater than zero, equal to $3,000,000.00 (the "Conditional Payment") less all amounts deducted from the Conditional Payment pursuant to Section 9.5. If there has been any reduction of the Conditional Payment pursuant to Section 9.5, Purchaser shall notify Seller in writing of the final amount payable to Seller at least 5 Business Days prior to the First Anniversary and provide Seller with a description of how such final amount was calculated.

10.2 Reserves for Unresolved Indemnifiable Losses. Notwithstanding the foregoing, if prior to the First Anniversary Purchaser has delivered a Claim Notice to Seller containing a claim for indemnification that has not been resolved in accordance with Section 9.5 prior to the First Anniversary, Purchaser may, until such claim is finally resolved in accordance with Section 9.5, deduct from the portion of the Conditional Payment otherwise payable to Seller pursuant to Section 10.1, an amount equal to the Claimed Amount or the Contested Amount, as the case may be. Upon the final resolution of all claims by Purchaser pending as of the First Anniversary, and upon the satisfaction of all Indemnifiable Losses resulting therefrom, Purchaser shall distribute the remaining portion of the Conditional Payment, if any, with interest at the then applicable judgment rate of interest in the State of Texas accruing from the First Anniversary to the date of payment, to Seller. Notwithstanding anything to the contrary herein, Purchaser shall deduct and withhold from any payment required to be made pursuant hereto any amount required by law to be so deducted and withheld.

11.3 Successors and Assigns. This Agreement will be binding upon and inure to the benefit of the parties hereto and their respective successors and permitted assigns, but will not be assignable or delegable by any party without the prior written consent of the other party; provided, however, that upon notice to the other party delivered in accordance with Section 11.1, either party may assign or delegate any or all of their rights or obligations under this Agreement to any Affiliate thereof or to any Person that directly or indirectly acquires, after the Closing, all or substantially all of the assets or voting stock of such party, but such assignment or delegation shall not relieve the assigning party of any obligation hereunder.

11.4 Waiver. No failure on the part of any Person to exercise any power, right, privilege or remedy under this Agreement, and no delay on the part of any Person in exercising any power, right, privilege or remedy under this Agreement, shall operate as a waiver of such power, right, privilege or remedy; and no single or partial exercise of any such power, right, privilege or remedy shall preclude any other or further exercise thereof or of any other power, right, privilege or remedy. No Person shall be deemed to have waived any claim arising out of this Agreement, or any power, right, privilege or remedy under this Agreement, unless the waiver of such claim, power, right, privilege or remedy is expressly set forth in a written instrument duly executed and delivered on behalf of such Person; and any such waiver shall not be applicable or have any effect except in the specific instance in which it is given.

11.5 Entire Agreement; Disclosure Schedules. This Agreement, which includes the schedules, annexes and exhibits hereto, supersedes any other agreement, whether written or oral, that may have been made or entered into by any party relating to the matters contemplated hereby and constitutes the entire agreement by and among the parties hereto.

11.6 Amendments, Supplements, Etc. This Agreement may be amended or supplemented at any time by additional written agreements executed and delivered by each of the parties hereto.

11.7 Rights of the Parties. Nothing expressed or implied in this Agreement is intended or will be construed to confer upon or give any Person other than the parties hereto any rights or remedies under or by reason of this Agreement or any transaction contemplated hereby.

11.8 Further Assurances. From time to time, as and when reasonably requested by any party hereto, the other party will execute and deliver, or cause to be executed and delivered, all such documents and instruments, make such other deliveries and take such other actions as may be reasonably necessary to consummate the transactions contemplated by this Agreement.

11.9 Applicable Law. This Agreement and the legal relations among the parties hereto will be governed by and construed in accordance with the rules and substantive Laws of the State of Texas, United States of America, without regard to conflicts of law provisions thereof.

11.10 Execution in Counterparts. This Agreement may be executed in two or more counterparts, each of which will be deemed an original, but all of which together will constitute one and the same agreement.

11.11 Titles and Headings. Titles and headings to Sections herein are inserted for convenience of reference only, and are not intended to be a part of or to affect the meaning or interpretation of this Agreement.

11.12 Invalid Provisions. If any provision of this Agreement is held to be illegal, invalid, or unenforceable under any present or future Law, and if the rights or obligations under this Agreement of Seller on the one hand and Purchaser on the other hand will not be materially and adversely affected thereby, (a) such provision will be fully severable; (b) this Agreement will be construed and enforced as if such illegal, invalid, or unenforceable provision had never comprised a part hereof; (c) the remaining provisions of this Agreement will remain in full force and effect and will not be affected by the illegal, invalid, or unenforceable provision or by its severance from this Agreement; and (d) in lieu of such illegal, invalid, or unenforceable provision, there will be added automatically as a part of this Agreement a legal, valid, and enforceable provision as similar in terms to such illegal, invalid, or unenforceable provision as may be possible.

11.13 Bulk Sales. Purchaser waives compliance by Seller with the provisions of the so-called bulk sales Law of any applicable jurisdiction; provided, however, that Seller will indemnify, defend and hold harmless Purchaser in respect of any Indemnifiable Loss relating to, resulting from or arising out of Seller's failure so to comply with such Laws in connection with the transactions contemplated by this Agreement.

11.14 Specific Performance. The parties recognize that if Seller refuses to perform under the provisions of this Agreement, monetary damages alone will not be adequate to compensate Purchaser for its injury. Purchaser shall therefore be entitled, in addition to any other remedies that may be available, to obtain specific performance of the terms of this Agreement. If any action is brought by Purchaser to enforce this Agreement, Seller shall waive the defense that there is an adequate remedy at law.

11.15 Transfers. Purchaser and Seller will cooperate and take such action as may be reasonably requested by the other in order to effect an orderly transfer of the Transferred Assets with a minimum of disruption to the operations and employees of the businesses of Purchaser and Seller.
