(a) assume the Assumed Liabilities; and

(b) pay to Seller the sum of $3,875,000 (the “Consideration”), subject to adjustment pursuant to Section 1.6.

1.5 Payment of the Consideration. At the Closing, Buyer shall pay Seller the Consideration as follows:

(a) Buyer shall deliver a portion of the Consideration equal to $500,000 (together with interest accrued thereon from time to time, the “Escrow Funds”) to Wells Fargo Bank, as escrow agent (the “Escrow Agent”), by wire transfer of immediately available funds to an account designated in writing by the Escrow Agent. Subject to Section 1.13, the Escrow Funds shall be held in escrow by the Escrow Agent for a period of twelve (12) months pursuant to the terms of an escrow agreement substantially in the form attached hereto as Exhibit A (the “Escrow Agreement”) in order to provide a convenient source for the payment of: (i) any indemnification obligations of Seller pursuant to Article 7 or (ii) any Post-Closing Adjustment pursuant to Section 1.6(c); and

(b) At the Closing, Buyer shall pay to Seller the remaining portion of the Consideration by wire transfer of immediately available funds to an account or accounts designated in writing by Seller.

1.6 Working Capital Adjustment.

(a) Closing Adjustment. Prior to the date hereof Seller shall have prepared and delivered to Buyer:

(i) a statement (the “Estimated Closing Statement”) setting forth Seller’s good faith estimate of the Net Working Capital Amount of the Business as of the close of

5

business on the date immediately prior to the Closing Date prepared in accordance with GAAP, consistently applied, and the definition of Net Working Capital Amount, and containing the line items set forth in the sample working capital amount calculation set forth solely for illustration purposes on Schedule 1.6, without giving effect to the transactions contemplated herein (the “Estimated Net Working Capital Amount”); and

(ii) an estimated unaudited balance sheet of the Business (excluding the Excluded Assets and Retained Liabilities) as of the close of business on the date immediately prior to the Closing Date prepared in accordance with GAAP, consistently applied, without giving effect to the transactions contemplated herein (the “Estimated Closing Date Balance Sheet”).

The Estimated Closing Statement shall contain detailed calculations of the Estimated Net Working Capital Amount, and shall be accompanied by a certificate of an authorized officer of Seller certifying that the Estimated Closing Statement and Estimated Closing Date Balance Sheet were prepared in accordance with GAAP, consistently applied.

The Consideration shall be adjusted at Closing to the extent that the Estimated Net Working Capital Amount is less than or greater than $850,000 (the “Target Working Capital Amount” and such adjustment, the “Closing Adjustment”). If the Estimated Net Working Capital Amount is less than the Target Working Capital Amount, the Consideration shall be decreased on a dollar-for-dollar basis by the amount of the Closing Adjustment. If the Estimated Net Working Capital Amount is greater than the Target Working Capital Amount, the Consideration shall be increased on a dollar-for-dollar basis by the amount of the Closing Adjustment.

(b) Working Capital Determination. Not later than one hundred (100) days after the Closing Date, Buyer shall prepare and deliver to Seller:

(i) a statement (the “Closing Statement”) containing detailed calculations of the Net Working Capital Amount of the Business as of the close of business on the date immediately prior to the Closing Date prepared in accordance with GAAP, consistently applied, and the definition of Net Working Capital Amount, and containing the line items set forth in the sample working capital amount calculation set forth solely for illustration purposes on Schedule 1.6, without giving effect to the transactions contemplated herein; and

(ii) an actual unaudited balance sheet of the Business (excluding the Excluded Assets and Retained Liabilities) as of the close of business on the date immediately prior to the Closing Date, prepared in accordance with GAAP, consistently applied, without giving effect to the transactions contemplated hereby (the “Closing Date Balance Sheet”).

Buyer shall provide Seller with reasonable access to the work papers in connection with such calculations. With respect to Accounts Receivable not collected within ninety (90) days following the Closing Date and therefore excluded from the Net Working Capital Amount, to the

6

extent that Buyer subsequently receives cash in respect of such Accounts Receivable, Buyer shall promptly deliver such cash to Seller. Seller shall have thirty (30) days after delivery of the Closing Statement and the Closing Date Balance Sheet to notify Buyer in writing that Seller disputes any aspect of the Closing Statement or the Closing Date Balance Sheet, and if no such notice is given within such time period, the Closing Statement and the Closing Date Balance Sheet shall conclusively be deemed final. If Seller disputes any aspect of the Closing Statement or the Closing Date Balance Sheet, Buyer and Seller shall use commercially reasonable efforts to reconcile such disputes and reach agreement on a final Closing Statement and Closing Date Balance Sheet. In the event Buyer and Seller are unable to reach agreement on a final Closing Statement and Closing Date Balance Sheet within thirty (30) days following Seller’s delivery of the dispute notice, then Buyer and Seller shall submit the remaining issues in dispute to KPMG (the “Selected Accountants”), which firm shall resolve such dispute within thirty (30) days following its selection. Buyer and Seller shall cooperate with the Selected Accountants in all respects, including providing the Selected Accountants with all work papers and back-up materials used in preparation and review of their calculations of the Closing Statement and the Closing Date Balance Sheet. Buyer and Seller acknowledge and agree that the Selected Accountants shall have the authority to determine all matters related to the dispute notice and that such determination by the Selected Accountants, including with respect to the Closing Statement and the Closing Date Balance Sheet, shall be final, binding and conclusive upon the Parties. The fees, expenses and costs of the Selected Accountants shall be paid by Seller, on the one hand, and Buyer, on the other hand, based upon the percentage that the amount actually contested but not awarded to Seller or Buyer, respectively, bears to the aggregate amount actually contested by Seller and Buyer. The Procedures set forth in this Section 1.6 for resolving disputes with respect to any aspect of the Closing Statement or the Closing Date Balance Sheet shall be the sole and exclusive method for resolving any such disputes.

(c) Post-Closing Adjustment. Subject to the resolution of all disputes, if any, regarding the Closing Statement and the Closing Date Balance Sheet in accordance with Section 1.6(b) above, the Consideration shall be further adjusted to the extent that the final Net Working Capital Amount as determined in clause “(b)” above is: (i) less than Estimated Net Working Capital Amount minus $100,000 (the “Target Working Capital Minimum”) or (ii) greater than Estimated Net Working Capital Amount plus $100,000 (the “Target Working Capital Maximum” and such adjustment as reflected in clauses “(i)” and “(ii)”, the “Post-Closing Adjustment”).

If the Net Working Capital Amount is less than the Target Working Capital Minimum, then the Consideration will be decreased on a dollar-for-dollar basis by the amount by which the Target Working Capital Minimum exceeds the final Net Working Capital Amount (the “Shortfall Post-Closing Adjustment”) and the Escrow Agent shall release the amount of the Shortfall Post-Closing Adjustment to Buyer from the Escrow Funds in satisfaction thereof; provided, however, that notwithstanding the foregoing, to the extent the Shortfall Post-Closing Adjustment exceeds the lesser of (i) $200,000 or (ii) the amount of the remaining Escrow Funds, Seller shall pay such excess amount in cash funds to Buyer within five (5) Business Days after the date on which the Closing Statement and the Closing Date Balance Sheet are determined to be final pursuant to Section 1.6(b) above. If the Net Working Capital Amount is greater than the Target Working Capital Maximum, then the Consideration will be increased on a dollar-for-dollar basis by the amount by which the final Net Working Capital Amount exceeds the Target Working Capital Maximum (the “Surplus Post-Closing Adjustment”), and Buyer shall, within five (5) Business

7

Days after the date on which the Closing Statement and the Closing Date Balance Sheet are determined to be final pursuant to Section 1.6(b) above, pay cash funds in an amount equal to the Surplus Post-Closing Adjustment to Seller.

1.7 Transfer of Purchased Assets and Assumption of Assumed Liabilities. At the Closing, Seller shall deliver or cause to be delivered to Buyer: (a) a Bill of Sale substantially in the form attached hereto as Exhibit B (the “Bill of Sale”); (b) an Assignment and Assumption Agreement substantially in the form attached hereto as Exhibit C (the “Assumption Agreement”); and (c) an Intellectual Property Assignment substantially in the form attached hereto as Exhibit D (the “IP Assignment”).

1.8 Delivery of Records and Contracts. At the Closing, Seller shall deliver or cause to be delivered to Buyer all written leases, contracts and other written documents included in the Purchased Assets and Assumed Liabilities. Seller shall deliver the tangible Purchased Assets to Buyer at 3501 Tri-Center Boulevard, Durham, North Carolina 27713 (the “Facility”).

1.9 Closing. The closing of the sale and purchase of the Purchased Assets and the transactions contemplated hereby (the “Closing”) shall take place contemporaneously with the execution of this Agreement (the date of such closing, the “Closing Date”) by the release of documents by the Parties after delivery thereof by overnight or electronic transmission, at such place mutually agreed by the Parties. The Closing will be deemed effective at 12:01 a.m. or such other time to be mutually agreed to by the parties on the Closing Date.

1.10 Allocation of Consideration. Not later than ninety (90) days following the Closing, Buyer shall prepare and deliver to Seller a statement of allocation which shall provide for the allocation of the Consideration, plus the Assumed Liabilities, to the extent properly taken into account pursuant to the provisions of Section 1060 of the Code, among the Purchased Assets and the covenants contained in Article 8 (the “Allocation Schedule”). Such Allocation Schedule shall be prepared in accordance with the provisions of Code Section 1060 and the Treasury Regulations thereunder (the “Allocation Principles”). Within twenty (20) days after the receipt of such Allocation Schedule, Seller will propose to Buyer in writing any changes to such Allocation Schedule together with reasonable documentation supporting such changes (and in the event that no such changes are proposed in writing to Buyer within such time period, Seller will be deemed to have agreed to, and accepted, the Allocation Schedule as delivered). Buyer and Seller will attempt in good faith to resolve any differences with respect to the Allocation Schedule, in accordance with the Allocation Principles, within fifteen (15) days after Buyer’s receipt of a timely written notice of objection from Seller. If Buyer and Seller are unable to resolve such differences within such time period, then any remaining disputed matters will be submitted to the Selected Accountants for resolution, in accordance with the Allocation Principles. Promptly, but not later than fifteen (15) days after such matters are submitted to it for resolution hereunder, the Selected Accountants will determine those matters in dispute and will render a written report as to the disputed matters and the resulting allocation of such amounts, which report shall be conclusive and binding upon Buyer and Seller. The fees and expenses of the Selected Accountants in respect of such report shall be paid one-half by Buyer and one-half by Seller. Buyer and Seller shall each file or cause to be filed their Tax Returns for their taxable years that include the Closing Date in a manner consistent with the allocation set forth on the Allocation Schedule as so finalized, and (except as set forth below relating to a revised

8

Allocation Schedule) shall not take any position on any Tax Return or in the course of any Tax audit, review, or litigation inconsistent with the allocation provided in the Allocation Schedule. In the event that any adjustment is required to be made to the Allocation Schedule as a result of any adjustment to the Consideration pursuant to this Agreement, Buyer shall prepare or cause to be prepared, and shall provide to Seller, a revised Allocation Schedule reflecting such adjustment. Such revised Allocation Schedule shall be subject to review and resolution of timely raised disputes in the same manner as the initial Allocation Schedule. Each of Buyer and Seller shall file or cause to be filed their Tax Returns reflecting such adjustments as so finalized for their taxable years that include the event or events giving rise to such adjustment, and (except as required by future revised Allocation Schedule) shall not take any position on any Tax Return or in the course of any Tax audit, review, or litigation inconsistent with the allocation provided in the revised Allocation Schedule.

1.11 Transfer Taxes. All transfer, excise, documentary, sales, use, stamp, registration, and other similar Taxes and fees (including any penalties and interest) incurred in connection with the consummation of the transactions contemplated by this Agreement (the “Transfer Taxes”) shall be borne one-half by each of Seller and Buyer. Buyer and Seller shall cooperate in (i) determining the amount of Transfer Taxes, (ii) using commercially reasonable efforts to provide all requisite certificates or other similar documents providing for an exemption to or reduction of such Transfer Taxes and (iii) preparing and timely filing any and all required Tax Returns for or with respect to such Transfer Taxes with any and all appropriate Tax authorities.

1.12 Withholding. Buyer and the Escrow Agent shall be entitled to deduct and withhold from any amounts otherwise payable pursuant to this Agreement (or, as the case may be, be promptly reimbursed therefor) such amounts as it reasonably determines that it is required to deduct and withhold with respect to the making of such payment under the Code or any provision of state, local, provincial or foreign Tax law; provided that prior to making any such deduction or withholding from the amounts that are otherwise payable to the Seller by the Buyer, the Buyer shall notify the Seller and cooperate in good faith with the Seller to use commercially reasonable efforts identified by the Seller to mitigate any such requirement to deduct or withhold to the extent permitted by applicable Law. To the extent that amounts are so withheld and properly remitted to the appropriate Tax authorities in accordance with applicable law, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Person entitled to receipt of the payment in respect of which such deduction and withholding was made by Buyer. Any such withholding shall be paid by Buyer to the appropriate authorities on a timely basis.

1.13 Escrow. The Escrow Funds will be deposited in trust and will be held and distributed solely for the purpose and in accordance with the terms of the Escrow Agreement. In accordance with the terms set forth in the Escrow Agreement, the Escrow Funds, other than such portion, if any, to be paid to Buyer, will be held by the Escrow Agent. The Escrow Agent will be required to release the Escrow Funds to Seller, except for amounts previously paid to Buyer therefrom or subject to a pending claim for indemnification pursuant to Article 7, on the twelve (12) month anniversary of the Closing Date. The fees and expenses of the Escrow Agent will be paid equally by Seller and Buyer, and the Parties will indemnify the Escrow Agent against actions taken by the Escrow Agent pursuant to the Escrow Agreement other than for acts or omissions which constitute intentional misconduct or gross negligence.

No issue relating to Seller with respect to the Business or the Purchased Assets or involving any Tax for which Seller might be liable with respect to the Business or the Purchased Assets has been resolved in favor of any taxing authority in any audit or examination which, by application of the same principles, could reasonably be expected to result in a deficiency for Taxes for any other period.

None of such inventory is obsolete and no write-down

15

of such inventory has been made or should have been made in the period since the Statement Date other than in the ordinary course of business.

(d) To the knowledge of the Seller, neither the conduct of the Business by Seller nor the services or products of Seller offered in the operations of the Business infringe, or violate, any Intellectual Property Rights of any third party in any material respects.

(a) On and after the Closing Date, each of the Parties shall execute such documents, further instruments of sale, transfer, conveyance, assignment and confirmation and other papers and take such further actions as may be reasonably required to: (x) transfer, convey and assign to Buyer, and to confirm Buyer’s title to, all of the Purchased Assets; and (y) carry out and give effect to the assumption of Assumed Liabilities by Buyer. Each Party shall use its commercially reasonable efforts to take such other actions to ensure that, to the extent within its control or capable of influence by it, the transactions contemplated by this Agreement shall be fully carried out in a timely fashion. Seller will not take any action that is designed or intended to have the effect of discouraging any lessor, lessee, licensee, licensor, supplier, customer or employee of Seller or any other Person with whom Seller has a relationship from maintaining the

27

same relationship with Buyer after the Closing as it maintained with Seller prior to the Closing. Seller will refer all customer inquiries relating to the Business to Buyer from and after the Closing.

(b) The Parties agree to furnish or cause to be furnished to each other, upon request, as promptly as practicable, such information and assistance relating to the Purchased Assets as is reasonably necessary for the filing of all Tax Returns, and making of any election related to Taxes, the preparation for any audit by any Governmental Entity, and the prosecution or defense of any claim, suit or proceeding relating to any Tax Return, including without limitation any audit or Tax working papers. The Parties shall cooperate with each other in the conduct of any audit or other proceeding related to Taxes involving the Business and each shall execute and deliver such powers of attorney and other documents as are necessary to carry out the intent of this Section 4.1(c). In addition, Buyer and Seller, with respect to the documents referred to in this Section 4.1(c), agree to maintain such records for a period of six (6) years from due date (including extensions) for the federal income Tax Returns of Seller and Buyer for the year that includes the Closing Date and each such Party agrees to afford the other reasonable access to such records during normal business hours.

4.2 Assignment of Contracts. To the extent that any lease, license, contract, agreement, sales or purchase order of Seller included in the Purchased Assets, or any claim, right or benefit arising thereunder or resulting therefrom (each, an “Interest”), is not capable of being sold, assigned, transferred or conveyed without causing a violation of applicable Laws and Regulations or without the authorization, approval, consent or waiver of the issuer thereof or the other party or parties thereto, or any other Person, including a Governmental Entity (or if such Interest would be breached in the event of a sale, assignment, transfer or conveyance without such approval, consent or waiver), then (a) this Agreement shall not, in the event such issuer or other Person shall object to such assignment, constitute an assignment or conveyance thereof absent such approval, consent or waiver and (b) Seller shall use its commercially reasonable efforts to obtain all such necessary approvals, consents or waivers necessary to convey to Buyer each such Interest. To the extent any of the approvals, consents or waivers referred to in this Section 4.2 have not been obtained as of the Closing, Seller shall, for a period of time commencing on the Closing Date and ending on the earlier of twelve (12) months following the Closing or the expiration of the remaining term of such Interest, exercise its commercially reasonable efforts to cooperate with Buyer, at its request, in any reasonable and lawful arrangements designed to provide the benefits of such Interest to Buyer.

All real property Taxes, personal property Taxes and similar ad valorem obligations levied with respect to any Purchased Assets for a taxable period which includes (but does not end on) the Closing Date, whether or not imposed or assessed before or after the Closing Date, shall be apportioned between Seller and Buyer based on the number of days of such taxable period through the Closing Date (the “Pre-Closing Property Tax Period”) and the number of days of such taxable period after the Closing Date (the “Post-Closing Property Tax Period”). Seller shall be liable under this Section 4.4 for the proportionate amount of such Taxes that is attributable to the Pre-Closing Property Tax Period, and Buyer shall be liable for the proportionate amount of such Taxes that is attributable to the Post-Closing Property Tax Period. Within ninety (90) days after the Closing, Seller and Buyer shall present a statement to the other setting forth the amount of reimbursement to which each is entitled under this Section 4.4 together with such supporting evidence as is reasonably necessary to calculate the amount of such reimbursement. Thereafter, upon receipt of any bill for such Taxes, Buyer or Seller, as applicable, shall notify the other Party of the receipt of such bill and shall present a statement to the other Party setting forth the amount of reimbursement to which it shall be entitled under this Section 4.4 upon payment of such bill, together with such supporting evidence as is reasonably necessary to calculate the amount of reimbursement.

Seller agrees to cooperate with Buyer and use commercially reasonable efforts to cause the Designated Employees to accept employment with Buyer. Seller hereby consents to the hiring of such Designated Employees by Buyer and waives any claims or rights Seller may have against Buyer or any such Designated Employees under any non-competition, confidentiality or employment agreement arising out of or relating to the employment by Buyer of such Designated Employees.

(b) On the Closing Date, Seller shall terminate the employment of all Designated Employees who accept an offer of employment from Buyer (each, a “Continuing Employee”) and provide such employees with written notice of termination.

7.5 Satisfaction of Indemnification Claims. Subject to Section 7.6, any claim by Seller for Losses under Section 7.4 shall be payable by Buyer in cash, by wire transfer, check or other method acceptable to Seller.

7.6 Limitation on Indemnification. The obligations of the Parties to indemnify one another under this Article 7 shall be subject to the following limitations:

(a) Time Limitations on Claims. No indemnification shall be payable pursuant to Section 7.2(a) or Section 7.4(a) unless the applicable Indemnitee provides the applicable Indemnitor (as such terms are defined below) with a written claim for Losses with respect thereto on or prior to the twelve (12) month anniversary of the Closing Date, except that indemnification for claims based on any inaccuracy or breach of the representations made in Sections 2.1 (Organization), 2.2 (Authority), 2.6 (Compliance with Laws), 2.7 (Tax Matters), 2.8 (Litigation), 2.9(b) and (c) (Properties; Title to Assets), 2.11 (Intellectual Property), 2.16 (Environmental Matters), 2.19 (Relationships with Affiliates), 2.25 (Broker’s Fee), 3.1 (Organization), 3.2(Authority to Execute and Perform Agreements) and 3.4 (Broker’s Fee) (such claims referred to above being collectively referred to as the “Specified Claims”), shall be payable until the expiration of the applicable statutes of limitation, including any extensions thereof.

(b) Threshold on Losses. No Losses shall be paid pursuant to Section 7.2(a) or 7.4(a) unless and until the aggregate claims for Losses exceed $50,000 (the “Threshold”), after which the applicable Indemnitee shall be entitled to all such Losses commencing from the first dollar of all such Losses. Notwithstanding the foregoing, the Threshold shall not apply to Specified Claims.

(c) Ceiling on Claims for Losses. Except for any Losses incurred as a result of a Specified Claim, the maximum aggregate liability of the applicable Indemnitor for indemnification under Section 7.2(a) or Section 7.4(a) shall not exceed: (x) with respect to Buyer as Indemnitor, an amount equal to the Escrow Funds, and (y) with respect to Seller as Indemnitor, funds available in the Escrow Fund. For Losses incurred as a result of any Specified Claim or for indemnification pursuant to Section 7.2(b) or Section 7.4(b), the maximum aggregate liability of the applicable Indemnitor under Section 7.2(a), Section 7.2(b) or Section 7.4(b), as applicable, shall not exceed an amount equal to the Consideration actually received by

35

Seller, as adjusted pursuant to the terms of this Agreement. For the avoidance of doubt, in the event a claim by an applicable Indemnitor could be brought under either Sections 7.2(a) or 7.2(c), on the one hand, or Sections 7.4(a) or 7.4(c), on the other hand, Buyer or Seller, as the case may be and at its sole discretion, may elect to bring such claim under either subpart (a) or (c), or under both such subsections.

(d) Punitive Damages; Net of Insurance Recovery. Notwithstanding anything to the contrary contained herein, Losses shall not include punitive, special, exemplary or unforeseeable damages. The amount of any Losses subject to indemnification under Section 7.2 or 7.4 shall be calculated net of any insurance proceeds applicable to such Losses and actually recovered by Buyer or Seller, as applicable, under applicable insurance policies.

7.7 Assertion of Claims.

(a) Notice of Claim. After becoming aware of any Losses for which either Buyer or Seller may seek indemnification hereunder (such Party, an “Indemnitee”), such Indemnitee shall give written notice thereof to either Buyer or Seller, as applicable (an “Indemnitor”), demanding payment, subject to Section 7.6, of an indemnification claim arising under Section 7.2 or Section 7.4 (a “Demand”), and, if the Seller is the Indemnitor and the Escrow Agreement has not terminated, copying the Escrow Agent. Such Demand shall describe in reasonable detail the nature of the claim, an estimate of the amount of Losses attributable to such claim (to the extent then known) and the basis of Indemnitee’s request for indemnification under this Agreement. Subject to Section 7.7(a), no delay on the part of the Indemnitee in notifying the Indemnitor under this Section 7.7 shall relieve the Indemnitor from any obligation hereunder, except to the extent that the Indemnitor shall have been materially adversely affected by such delay.

(b) Response to a Demand. The Indemnitor may reply to a Demand made under Section 7.7(a) hereof by written notice given to the Indemnitee and, if the Seller is the Indemnitor and the Escrow Agreement has not terminated, the Escrow Agent, which notice shall state (i) whether Indemnitor agrees or disagrees that the claim asserted is a valid claim under this Agreement and agrees or disagrees with respect to the amount of the Losses in such Demand and (ii) if Indemnitor disagrees with either the validity of such claim or the amount of such Losses, the basis for such disagreement.

(i) If the Indemnitor does not give the Indemnitee and, if the Seller is the Indemnitor and the Escrow Agreement has not terminated, the Escrow Agent a notice disputing such Demand within forty five (45) days after receipt of the Demand (the “Indemnity Notice Period”) or Indemnitor gives notice that such Demand is uncontested, then: (x) if Seller is the Indemnitor and the Escrow Agreement has not terminated, the Escrow Agent shall release from the Escrow Funds and deliver to Buyer the amount of the Losses stated in the Demand (to the extent that such losses do not exceed the Escrow Funds); (y) if Buyer is the Indemnitor, Buyer shall pay Seller the amount of Losses stated in the Demand. If (1) Seller is the Indemnitor and the Escrow Agreement has not terminated, and the notice from the Seller admits that a portion of the Demand is a valid claim under Section 7.2 and the remaining portion of the Demand is disputed, the Escrow Agent shall disburse to Buyer only such amounts from the Escrow Funds as are allocable to mutually agreed Losses (to the extent that such agreed Losses

36

do not exceed the Escrow Funds), and the disputed portion of such Demand shall be resolved in accordance with Section 7.7(c); and (2) If Buyer is the Indemnitor, and the notice from Buyer admits that a portion of the Demand is a valid claim under Section 7.3 and the remaining portion of the Demand is disputed, Buyer shall pay to Seller only such amounts as are allocable to mutually agreed Losses (subject to the limitations negotiated in Section 7.6), and the disputed portion of such Demand shall be resolved in accordance with Section 7.7(c).

(ii) If either (A) Seller is the Indemnitor and either (1) the Escrow Agreement has not terminated and the Losses payable pursuant to Section 7.7(b)(i) above exceed the Escrow Funds, or (2) the Escrow Agreement has terminated (subject to the limitations on indemnification sect forth in Section 7.6) or (B) Buyer is the Indemnitor, and the Indemnitor does not give the Indemnitee a notice disputing such Demand and specifying the nature and amount of such dispute within the Indemnity Notice Period or the Indemnitor gives notice that such Demand or a portion thereof is uncontested; then, in the case of (A) or (B) above, the Indemnitor shall deliver payment to the Indemnitee in cash an amount equal to the value of the Losses (and in the case of clause (A) above, less any amounts received by Buyer from the Escrow Funds with respect to such Losses) stated in the Demand within fifteen (15) days of the earlier of expiration of such Indemnity Notice Period or notice that the Demand is uncontested. If the notice from the Indemnitor admits that a portion of the Demand is a valid claim under Section 7.2 and the remaining portion of the Demand is disputed, the Indemnitor shall pay to the Indemnitee in cash an amount equal to the value of the Losses as are allocable to mutually agreed upon Losses (and in the case of clause (A) above, less any amounts received by Buyer from the Escrow Funds with respect to such Losses) within fifteen (15) days of delivery of such notice from the Indemnitor, and the disputed portion of such Demand shall be resolved in accordance with Section 7.7(c).

(c) Disputed Claims. If the notice given by the Indemnitor as provided in Section 7.7(b) hereof disputes all or part of the claim or claims asserted in the Demand by the Indemnitee or the amount of Losses thereof, within the Indemnity Notice Period (a “Disputed Claim”), then, to the extent of the disputed portion of the Demand, the Demand shall be treated as a Disputed Claim and, if the Seller is the Indemnitor and the Escrow Agreement has not terminated, the amount of such claim shall be held by the Escrow Agent. The Parties hereto shall make a reasonable good faith effort to resolve their differences for a period of thirty (30) days following the Indemnity Notice Period asserting a Disputed Claim. If the Seller is the Indemnitor, the Escrow Agent shall not disburse any Escrow Funds as to a Disputed Claim until the final determination of Seller liability to Buyer.

(d) Third Party Claims. After receipt of any assertion of Losses by any third party (“Third Party Claims”) that might give rise to any Losses for which indemnification may be sought pursuant to Section 7.2 or 7.4, the Indemnitee shall promptly give written notice of such Third Party Claim (a “Notice of Third Party Claim”) to the Indemnitor and, if the Seller is the Indemnitor and the Escrow Agreement has not terminated, copying the Escrow Agent, which Notice shall state the (i) nature, basis and facts giving rise to such Third Party Claim, (ii) the specific representation(s), warranty(ies) or covenant(s) with respect to which such Third Party Claim is made, (iii) the amount of Losses or the estimated amount thereof to the extent known and feasible, and (iv) the amount of liability asserted against the Indemnitor by reason of the Third Party Claim. Such Notice of Third Party Claim shall be accompanied by copies of all

37

relevant documentation with respect to such Third Party Claim. Notwithstanding the foregoing, the failure to provide notice as aforesaid to the Indemnitor (and the Escrow Agent, if applicable) will not relieve the Indemnitor from any liability which it may have to the Indemnitee under this Agreement or otherwise except to the extent that the Indemnitor shall have been materially adversely affected by such failure.

(e) Defense of Third Party Claims. The Indemnitor may elect to defend any Third Party Claim (an “Election to Defend”) with counsel of its own choosing, reasonably acceptable to the Indemnitee, so long as (i) within ten (10) days after receipt of notice of the Third Party Claim, the Indemnitor notifies the Indemnitee in writing that the Indemnitor will, subject to the limitations of this Article 7, indemnify the Indemnitee from and against any Losses that the Indemnitee may incur relating to or arising out of the Third Party Claim, (ii) the Indemnitor provides the Indemnitee with evidence that the Indemnitor has the financial resources to defend against the Third Party Claim and fulfill its indemnification obligations hereunder, (iii) the Indemnitee has determined in good faith that there would be no conflict of interest with respect to the Election to Defend, (iv) the Third Party Claim does not involve, and is not likely to involve, any claim by any Governmental Entity, (v) the Third Party Claim involves only money damages and does not seek an injunction or other equitable relief or involve a criminal matter, (vi) the amount of the Third Party Claim does not exceed the amount of the Consideration, (vii) settlement of, or an adverse judgment with respect to, the Third Party Claim is not, in the good faith judgment of the Indemnitee, likely to establish a precedential custom or practice adverse to the continuing business interests of the Indemnitee or the Indemnitor or injure the Indemnitee’s reputation, customer or supplier relations or future business prospects, (viii) the Indemnitor conducts the defense of the Third Party Claim actively and diligently, and (ix) the Indemnitor keeps the Indemnitee apprised of all material developments, including settlement offers, with respect to the Third Party Claim and permits the Indemnitee to participate, at its own expense, through counsel of the Indemnitee’s choice, in the defense of the Third Party Claim. No Third Party Claim may be settled without the consent of the Indemnitee, which shall not be unreasonably withheld or delayed. An Election to Defend constitutes an admission that such claim is within the scope of the Indemnitor’s indemnification obligations hereunder. If the Indemnitor chooses not to defend any Third Party Claim by failure to deliver on a timely basis the Election to Defend or by failure to meet the conditions specified above, the Indemnitee may defend against such Third Party Claim, consent to the entry of any judgment or enter into any settlement with respect to the Third Party Claim in any manner it may deem appropriate, and solely if the Indemnitee proves its right for indemnification pursuant to Section 7 also obtain indemnification pursuant to this Article 7 for Losses resulting from such Third Party Claim. In addition, if the Indemnitor has assumed defense of the Third Party Claim and if a potential or actual conflict of interest shall exist or if different defenses shall be available between the Indemnitor and the Indemnitee, then the Indemnitee shall be entitled to retain separate legal counsel and submit the fees and expenses of such counsel as part of a Demand pursuant to Section 7.2. Notwithstanding the foregoing, the Indemnitee will at all times have the right to fully participate in such defense at its own expense directly or through counsel. Each Party shall make available to each other and their counsel and accountants all books and records and information relating to any Third Party Claim, keep each other fully apprised as to the details and progress of all proceedings relating thereto and render to each other such assistance as may be reasonably required for the proper and adequate defense of any Third Party Claim.

38

7.8 Tax Treatment. The Parties agree to treat all payments made by or deemed to be made by a Party under this Article 7 as adjustments to the Consideration hereunder unless otherwise required by applicable law.

7.9 Related Persons. Notwithstanding anything that may be expressed or implied in this Agreement, Seller acknowledges and agrees that (a) no recourse hereunder or under any document or instrument delivered in connection herewith may be had against any director, officer, agent, partner, management company or employee of any stockholder of Buyer or any entity or individual affiliated therewith (whether such affiliate is a partner, member, stockholder or otherwise), or any direct or indirect director, officer, employee, partner, affiliate, member, controlling person or representative of any of the foregoing (any such Person, a “Related Person”), whether by the enforcement of any judgment or assessment or by any legal or equitable proceeding, or by virtue of any statute, regulation or other applicable law; and (b) no personal liability whatsoever will attach to, be imposed on or otherwise be incurred by any Related Person under this Agreement or any document or instrument delivered in connection herewith, or for any claim based on, in respect of or by reason of such obligations, and all such claims against the Related Persons are hereby waived and released.

7.10 Exclusivity. Except as provided in Section 10.11 and except for claims for fraud or fraudulent concealment, the indemnities set forth in this Article 7 shall be the exclusive remedies of the Parties for any misrepresentation, breach of warranty or nonfulfillment or failure to perform any covenant or agreement contained in this Agreement, and the Parties shall not be entitled to any further indemnification rights or claims of any nature whatsoever in respect thereof. Nothing in this Section 7.10 shall operate to interfere with or impede the operation of the provisions of Section 1.6.

ARTICLE 8

NON-COMPETITION AND NON-SOLICITATION COVENANTS

8.1 Non-Competition and Non-Solicitation. As further consideration for the purchase and sale of the Purchased Assets and the other transactions contemplated by this Agreement:

(a) For a period ending on the third (3rd) anniversary of the Closing Date (the “Restriction Period”), Seller shall not directly or indirectly engage in any business competitive to the Business; and

(b) Seller agrees during the Restriction Period, not to, directly or indirectly:

(i) employ or hire any person who is a Designated Employee, unless the employment of such Designated Employee is terminated by Buyer or any of its Affiliates; or

(ii) call upon, solicit or communicate with any person who is a Designated Employee for the purpose or with the intent of enticing such Designated Employee away from Buyer or any of its Affiliates.

8.2 Confidentiality. Seller recognizes that the Purchased Assets include Confidential Information regarding the Business, that in connection with the transactions contemplated by this

39

Agreement certain other Confidential Information of Buyer may be disclosed to Seller, and that the use or disclosure of the Confidential Information by Seller or third parties would cause Buyer substantial losses and damages that could not be readily calculated and for which no remedy at law would be adequate. Accordingly, Seller covenants and agrees with Buyer not to at any time, directly or indirectly, use, disclose or publish, or permit other Persons (including Affiliates of Seller), to directly or indirectly use, disclose or publish, any Confidential Information, except as set forth herein or in the License Agreement or unless (a) such information becomes generally known to the public through no fault of Seller, (b) the disclosing party is advised by counsel that disclosure is required by law or the order of any Governmental Entity of competent jurisdiction under color of law, or (c) the disclosing party reasonably believes (based on advice of counsel) that such disclosure is required in connection with the defense of a lawsuit; provided, that prior to disclosing any information pursuant to clause (b) or (c) above, such Person shall give prior written notice thereof to Buyer and provide Buyer with the opportunity to contest or limit such disclosure and shall cooperate with efforts to prevent such disclosure at Buyer’s expense. Seller shall not divulge, disclose or communicate to others in any manner whatsoever, information or statements which disparage or are intended to disparage the Business or Buyer and its Affiliates or their respective business reputations.

8.3 Reasonable Restraint. The Parties agree that the foregoing covenants in this Article 8 impose a reasonable restraint on each of the Parties in light of the activities and business of the Parties on the date of the execution of this Agreement and the current plans of the Parties.

8.4 Severability; Reformation. The covenants in this Article 8 are severable and separate, and the unenforceability of any specific covenant shall not affect the provisions of any other covenant. Moreover, in the event any court of competent jurisdiction shall determine that the scope, time or territorial restrictions set forth are unreasonable, then it is the intention of the Parties that such restrictions be enforced to the fullest extent which the court deems reasonable, and the Agreement shall thereby be reformed.

8.5 Independent Covenant. All of the covenants in this Article 8 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 a Party against the other Party, whether predicated on this Agreement or otherwise, shall not constitute a defense to the enforcement by either Party of such covenants. The Parties expressly acknowledge that the terms and conditions of this Article 8 are independent of the terms and conditions of any other agreements entered into in connection with this Agreement. It is specifically agreed that the periods set forth in this Article 8 during which the agreements and covenants made in this Article 8 shall be effective, shall be computed by excluding from such computation any time during which the Person bound by such agreement or covenant is found by a court of competent jurisdiction to have been in violation of any provision of this Article 8. The covenants contained in this Article 8 shall not be affected by any breach of any other provision hereof by any Party hereto.

8.6 Materiality. Each of the Parties hereto hereby agrees that the covenants set forth in this Article 8 are a material and substantial part of the transactions contemplated by this Agreement and are supported by adequate consideration.

40

8.7 Successors and Assigns. Seller agrees and covenants that it shall require and cause any successor, whether direct or indirect, by purchase, merger, consolidation, operation of law or otherwise, of all or substantially all of the assets and/or business of Seller, to assume by written agreement, and perform all of the obligations of this Article 8 to the same extent as Seller would be required to perform such obligations if no such succession had taken place.
