(a) In furtherance of the transactions contemplated by this Agreement and in order to secure the interests of the parties hereto, Seller agrees that it will not, for a period of ten years following the Closing Date, for any reason whatsoever, directly or indirectly, for itself or on behalf of or in conjunction with any other Person: (i) engage in any activities related to developing, filing for and obtaining regulatory approval, and handling other regulatory affairs relating to, formulating, manufacturing, using, marketing, promoting, selling, distributing, commercializing, licensing, improving, or otherwise exploiting the Compounds or any compounds, preparations, procedures, methodologies, or products with ophthalmic application; or (ii) call upon any person who is at that time an employee of Buyer who is engaged in any aspect of Buyer's Compound-related business for the purpose or with the intent of enticing such employee away from or out of the employ of Buyer. (b) It is expressly understood and agreed that, if any of the agreements contained in this Section 5.10 are for any reason found to be unreasonably broad, oppressive or unenforceable in an action, suit or proceeding before any federal or state court, such court (i) shall narrow the covenant not to compete or shall otherwise endeavor to reform the scope of such agreements in order to ensure that the application thereof is not unreasonably broad, oppressive or unenforceable and (ii) to the fullest extent permitted by law, shall enforce such agreements as so reformed. (c) All of the covenants in this Section 5.10 shall be construed as an agreement independent of any other provision in this Agreement, and the existence of any claim or cause of action of Seller against Buyer, whether predicated on this Agreement or otherwise, shall not constitute a defense to the enforcement by Buyer of such covenants. It is specifically agreed that the period of ten years stated at the beginning of this Section 5.10, during which period the agreements and covenants of Seller made in this Section 5.10 shall be effective, shall be computed by excluding from such computation any time during which Seller is found by a court of competent jurisdiction to have been in violation of any provision of this Section 5.10. The covenants contained in Section 0 shall not be affected by any breach of any other provision hereof by an party hereto and shall have no effect if the transactions contemplated by this Agreement are not consummated. (d) Seller and Buyer hereby agree that the covenants set forth in this Section 5.10 are a material and substantial part of the transactions contemplated by this Agreement. (e) Because of the difficulty of measuring economic losses to Buyer as a result of a breach of the restrictive covenants set forth in this Section 5.10, and because of the immediate and irreparable damage that would be caused to Buyer for which monetary damages would not be a sufficient remedy, it is hereby agreed that in addition to all other remedies that may be available to 24 Buyer at law or in equity, Buyer shall be entitled to specific performance and any injunctive or other equitable relief as a remedy for any breach or threatened breach of the aforementioned restrictive covenants. 5.11 Expenses.

(a) Indemnification by Seller. Seller covenants and agrees to indemnify, defend, protect and hold harmless, Buyer and its officers, directors, employees, stockholders, assigns, successors and Affiliates (individually, a "Buyer Indemnified Party" and collectively, "Buyer Indemnified Parties") from, against and in respect of: (i) all Losses suffered, sustained, incurred or paid by any Buyer Indemnified Party in connection with, resulting from or arising out of or relating to, directly or indirectly: (A) any breach of any representation or warranty of Seller set forth in this Agreement or any certificate, document or instrument delivered by Seller in connection herewith; (B) any nonfulfillment of any covenant or agreement on the part of Seller in this Agreement; (C) claims or causes of actions relating in any way to the Assets arising from Seller's ownership or license of the Assets prior to the Closing; (D) claims or causes of actions arising subsequent to the Closing attributable to Seller's failure to comply with any bulk sales laws of any jurisdiction in connection with the sale of the Assets under this Agreement; (E) any negligent or reckless actions by Seller or its employees in connection with the fulfillment of its obligations set forth in this Agreement; and (F) non-compliance with the terms and conditions of any Bulk Sales Laws with respect to the transactions contemplated by this Agreement. 27 (ii) any and all Losses arising from the foregoing or to the enforcement of this Section 7.02(a). The provisions for indemnification contained in this Section 7.02(a) shall be effective only after the aggregate amount of all Losses for which Seller is liable under this Agreement exceeds $50,000, in which case the Seller shall be obligated to indemnify the Buyer Indemnified Parties for the full amount of such Losses. In no event shall the maximum amount of all Losses for which Seller is liable pursuant to this Section 7.02(a) exceed $390,000, except for Losses, for which the Seller is liable, asserted against, resulting to, imposed upon, or incurred by Buyer Indemnified Parties by reason of or resulting from Seller's breach or non-performance of Section 3.17, 3.21, 5.09, or 5.10. (b) Indemnification by Buyer. Buyer covenants and agrees to indemnify, defend, protect and hold harmless, Seller and its officers, directors, employees, stockholders, assigns, successors and Affiliates (individually, a "Seller Indemnified Party" and collectively, the "Seller Indemnified Parties") from, against and in respect of: (i) all Losses suffered, sustained, incurred or paid by any Seller Indemnified Party in connection with, resulting from or arising out of or relating to, directly or indirectly: (A) any breach of any representation or warranty of Buyer set forth in this Agreement or any certificate or other writing delivered by Buyer in connection herewith; and (B) any nonfulfillment of any covenant or agreement on the part of Buyer set forth in this Agreement. (ii) any and all Losses arising from the foregoing or to the enforcement of this Section 7.02(b). (c) All Claims for indemnification under this Section 7.02 shall be asserted and resolved as follows: (i) Any party that may be entitled to indemnification under this Agreement, (an "Indemnified Party") shall send a Claim Notice (as defined below) to the party obligated to indemnify it (an "Indemnifying Party") with reasonable promptness upon becoming aware of any claim or other facts upon which a claim for indemnification might be based. If the Indemnifying Party does not notify the Indemnified Party within 30 days from the date of receipt of such Claim Notice that the Indemnifying Party disputes such claim, the amount of such claim shall be conclusively deemed a liability of the Indemnifying Party hereunder. In case the Indemnifying Party shall object in writing to any claim made in accordance with this Section 7.02, the Indemnified Party shall have 15 days to respond in a written statement to the objection of the Indemnifying Party. If after such 15 day period, there remains a dispute as to any claims, the parties shall attempt in good faith for 60 days to agree upon the rights of the respective parties with respect to each of such claims. If the parties should so agree, a memorandum setting forth such agreement shall be prepared and signed by both parties. 28 (ii) In the event that any claim for which an Indemnifying Party would be liable to an Indemnified Party hereunder is asserted against an Indemnified Party by a third party, the Indemnified Party shall with reasonable promptness notify the Indemnifying Party of such claim, including a copy of the claim made if the claim was made in writing, specifying the nature of such claim and the amount or the estimated amount thereof to the extent then feasible (which estimate shall not be conclusive of the final amount of such claim) (the "Claim Notice"). The Indemnifying Party shall have 30 days from the receipt of the Claim Notice (the "Notice Period") to notify the Indemnified Party (i) whether or not the Indemnifying Party disputes the Indemnifying Party's liability to the Indemnified Party hereunder with respect to such claim and (ii) if the Indemnifying Party does not dispute such liability, whether or not the Indemnifying Party desires, at the sole cost and expense of the Indemnifying Party, to defend against such claim, provided that the Indemnifying Party is hereby authorized (but not obligated) prior to and during the Notice Period to file any motion, answer or other pleading and to take any other action which the Indemnifying Party shall deem necessary or appropriate to protect the Indemnifying Party's interests. In the event that the Indemnifying Party notifies the Indemnified Party within the Notice Period that the Indemnifying Party does not dispute the Indemnifying Party's obligation to indemnify hereunder and desires to defend the Indemnified Party against such claim and except as hereinafter provided, the Indemnifying Party shall have the right to defend by appropriate proceedings, which proceedings shall be diligently settled or prosecuted by the Indemnifying Party to a final conclusion; provided that, unless the Indemnified Party otherwise agrees in writing, the Indemnifying Party may not settle any matter (in whole or in part) unless such settlement includes a complete and unconditional release of the Indemnified Party. If the Indemnified Party desires to participate in, but not control, any such defense or settlement the Indemnified Party may do so at the Indemnified Party's sole cost and expense. If the Indemnifying Party elects not to defend the Indemnified Party against such claim, whether by failure of the Indemnifying Party to give the Indemnified Party timely notice as provided above or otherwise, then the Indemnified Party, without waiving any rights against the Indemnifying Party, may settle or defend against any such claim in the Indemnified Party's sole discretion and the Indemnified Party shall be entitled to recover from the Indemnifying Party the amount of any settlement or judgment and, on an ongoing basis, all indemnifiable costs and expenses of the Indemnified Party with respect thereto, including interest from the date such costs and expenses were incurred. (iii) Nothing herein shall be deemed to prevent an Indemnified Party from making a claim, and an Indemnified Party may make a claim hereunder, for potential or contingent claims or demands provided the Claim Notice sets forth the specific basis for any such potential or contingent claim or demand to the extent then feasible and an Indemnified Party has reasonable grounds to believe that such a claim or demand may be made. (iv) Subject to Section 7.04, the Indemnified Party's failure to give reasonably prompt notice to the Indemnifying Party of any actual, threatened or possible claim or demand which may give rise to a right of indemnification hereunder shall not relieve the Indemnifying Party of any liability which the Indemnifying Party may have to the Indemnified Party unless the failure to give such notice materially and adversely prejudiced the Indemnifying Party. 29 7.03 Indemnification for Brokerage Claims. Seller and Buyer each represents that no broker or finder has been used in connection with the transactions contemplated by this Agreement and Seller and Buyer shall mutually indemnify the other against any claim for brokerage or like commission arising from each other's conduct or alleged conduct. 7.04 Survival of Representations, Warranties, Covenants and Indemnifications. All representations, warranties, covenants and indemnifications contained in this Agreement shall survive for a period of one year from the Closing Date and thereafter shall be of no force or effect. Any claim for indemnification with respect thereto must be asserted by written notice to the Indemnifying Party prior to such date. 7.05 Assignability and Amendments. This Agreement may not be assigned by either party without the prior written consent of the other party, which consent shall not be unreasonably withheld, except that, subsequent to the Closing Date, Buyer may assign this Agreement to any of its Affiliates, provided, that such Affiliates agree to be bound by the provisions of this Agreement. No such assignment will relieve the assigning party of any of its liabilities hereunder. This Agreement cannot be altered or otherwise amended except pursuant to an instrument in writing signed by each of the parties. 7.06 Notices. All notices or communications to be given hereunder will be deemed to have been duly given only if delivered personally or by facsimile transmission or by registered or certified mail (first class or air mail in the case of international correspondence, postage prepaid) or by an internationally recognized common carrier's overnight courier to the parties at the following addresses or facsimile numbers: If to Seller. addressed to: AcSentient, Inc. 110 Doric Court Morrisville, North Carolina 27560 Attention: Lisa T.
