     Section 2.04. Covenant Not To Compete.

          (a) The Seller, on behalf of itself and its Affiliates, hereby covenants and agrees that, for a period of six years beginning on the Closing Date (the “Restriction Period”), neither Seller nor its Affiliates shall, anywhere in the world, formulate, develop, produce, manufacture, market, sell or distribute (either through its own efforts or by contracting with or licensing a third party to do any of the foregoing) any product that (i) contains cyanocobalamin as an active ingredient formulated for intranasal delivery, (ii) can be used to determine glomerular filtration rate, (iii) can be utilized in the treatment of the indications set forth on Schedule 2.04, or (iv) contains the active ingredients contained in any of the Products (products includible in any of sub parts (i) – (iv) of the previous sentence, the “Competing Products”). Other products that contain the active ingredients contained in any of the Products shall not be considered Competing Products if the presence of such ingredient is present solely as a carrier and is not sold for treatment of any of the indications for which any of the Products are sold. During the Restriction Period, neither Seller nor its Affiliates shall prepare for or pursue (or assist a third party in preparing for or pursuing) an IND or NDA (in the USA, or its equivalent in any other country in the world) with respect to the Products (including any additional indications with respect thereto) or any Competing Product, nor shall Seller or any of its Affiliates formulate, develop, use, or commercially exploit (or assist any third party in such) the Products or the active ingredients thereof anywhere in the world for any usages (except usages solely as a carrier (but not as the active ingredient) for drugs to be utilized for indications other than those for which the Products are sold). For purposes of this Section 2.04, the provision of, or allowing access to, any Product related Know-how to third parties shall be considered “assisting” such third party in violation of this Section 2.04. This covenant shall not apply to then existing or future operations of any Person that acquires the Company (including its continuation of such then existing operations), by way of merger, stock purchase, asset purchase or otherwise, or any of such Person’s Affiliates provided such acquirer thereafter does not utilize any assets, rights, know-how, facilities, clinical data, sales or marketing or distribution systems of the Seller or its Affiliates (that were Affiliates prior to such acquisition), or any employees of the Seller or its Affiliates (that were Affiliates prior to such acquisition) in the activities that would, but for this sentence, be a violation of this Section 2.04. This covenant shall further not apply to any of Seller’s shareholders and other Affiliates of Seller that are not controlled or employed by Seller (“Excluded Affiliates”) provided that any such Excluded Affiliate does not utilize any assets, rights, know-how, facilities, clinical data, sales or marketing or distribution systems of Seller or obtained from the Seller (unless such was misappropriated or otherwise wrongfully obtained), or any employees of the Seller in the activities that would, but for this sentence, be a violation of this Section 2.04.

          (b) Seller, for itself and its Affiliates, acknowledges and agrees that (i) the covenants contained in this Section 2.04 are incident to the sale of the Business and the Products and are an important part of the consideration to be received by Buyer in exchange for the consideration paid by Buyer pursuant hereto; (ii) the activities prohibited by this Section 2.04 are not Seller’s only means for business and are not required for the continuation of its business; (iii) that the Buyer is relying on the covenants contained in this Section 2.04 in its decision to enter into this Agreement and purchase the Business and Purchased Assets; (iv) the Buyer has a right to protection from competition from the Seller and its current Affiliates during the Restriction Period; and (v) the Buyer has a valid interest in preventing such competition throughout the United States and the entire world.

          (c) Each of the provisions of this Section 2.04 shall be construed as an agreement independent of any other provision contained in this Section 2.04 or elsewhere in this Agreement, and the restrictions herein with respect to each of the States in the United States and each country in the world shall be an agreement independent of the restrictions with respect to the other States or other countries, and each provision (and the restrictions with respect to each such state or country) shall be enforceable in both law and equity, including by temporary or permanent restraining orders or injunctions, notwithstanding the existence of any claim or cause of action Seller may have or claim against Buyer, whether predicated on this Agreement or otherwise. In the event any provision of this Section 2.04, or the restrictions with respect the conduct that constitutes competition, to any one or more States or countries, or the time period of the restrictions, are held to be invalid or overbroad, then such provisions, States or countries shall be modified, reduced, or deleted if deemed appropriate, by the applicable court such that the remainder of this Section 2.04, restricted conduct, the States and countries included in the restricted territory, and the time period, as thus modified shall remain in full force and effect. During each period in which Seller is in breach of this Section 2.04 of this Agreement, the Restriction Period in the applicable country shall be extended for the length of each such period of breach. Seller acknowledges and agrees that a breach by Seller of the covenants set forth in this Section 2.04 will cause irreparable damage to Buyer and the Business and, therefore, Seller agrees that in the event it or its Affiliates breaches any of such covenants, Buyer is entitled to a grant of injunctive relief from a court of competent jurisdiction in addition to any and all other remedies allowed by law or in equity, without the requirement to post bond.

REPRESENTATIONS AND WARRANTIES OF SELLER

     Seller represents and warrants to Buyer as of (i) the date hereof and (ii) the Closing Date, except as to certain representations and warranties which expressly speak as of a date certain, which shall speak as of such date, subject to such exceptions as are disclosed in the disclosure schedule (that constitutes a part of this Agreement) supplied by Seller to Buyer and dated as of the date hereof (the “Seller Disclosure Schedule”), as follows (each Seller Disclosure Schedule shall be titled to identify it as a specific schedule referenced in this Agreement and the disclosures on each such schedule shall relate to and modify only the specific Sections or representations hereof that reference such individual Schedule):

     Section 6.01. Organization. Seller is duly organized, validly existing and in good standing under the laws of California and has requisite corporate power and authority to own its assets and

carry on the Business as currently conducted by it. Seller is duly authorized to conduct its business and is in good standing in each jurisdiction where such qualification is required, except for any jurisdiction where failure to so qualify would not have a Material Adverse Effect.

     Section 6.02. Authority of Seller. Seller has all necessary corporate power and authority and has taken all actions necessary to enter into and deliver this Agreement and the Related Agreements and carry out the transactions contemplated hereby and thereby. The shareholders and the board of directors of Seller have taken all action, if any, required by Law and its Charter Documents and otherwise to be taken by it to authorize (a) the execution and delivery of this Agreement and the Related Agreements and (b) the consummation of the transactions contemplated hereby and thereby. This Agreement has been duly and validly executed and delivered by Seller and, when executed and delivered by Buyer, will constitute a legal, valid and binding obligation of Seller enforceable against it in accordance with its terms. When executed and delivered by Seller and by Buyer, each Related Agreement will constitute a legal, valid and binding obligation of Seller, enforceable against it in accordance with its terms.

     Section 6.03. Consents and Approvals.

          (a) Schedule 6.03(a) of the Seller Disclosure Schedule sets forth a complete and accurate list (the “Seller Governmental Consents”) of all consents, waivers, approvals, Orders, permits or authorizations of, or registrations, declarations, payments or filings with, any Governmental or Regulatory Authority that are required by or with respect to Seller in connection with the execution and delivery of this Agreement and the Related Agreements by Seller, the transactions contemplated hereby and thereby or the performance of its obligations hereunder and thereunder.

          (b) Schedule 6.03(b) of the Seller Disclosure Schedule sets forth a complete and accurate list (the “Seller Third Party Consents”) of all consents, waivers, approvals, or authorizations of, or notices to, any third party (other than a Governmental or Regulatory Authority) that are required by or with respect to Seller in connection with the execution and delivery of this Agreement and the Related Agreements by Seller, the transactions contemplated hereby and thereby or the performance of its obligations hereunder and thereunder except for those consents, waivers, approvals, authorizations or notices which a failure to obtain or make would not have a Material Adverse Effect.

     Section 6.04. Non-Contravention. The execution and delivery by Seller of this Agreement and the Related Agreements, does not, and the performance by it of its obligations under this Agreement and the Related Agreements and the consummation of the transactions contemplated hereby and thereby will not, except as would not have a Material Adverse Effect:

          (a) conflict with or result in a violation or breach of any of the terms, conditions or provisions of the Charter Documents of Seller;

          (b) assuming the receipt of Seller Governmental Consents, conflict with or result in a violation or breach of any term or provision of any Law applicable to Seller, the Business as conducted by Seller or the Purchased Assets; or

          (c) conflict with or result in a Default under any Assumed Contract, assuming receipt of required consents to the assignment of such Assumed Contract to Buyer.

     Section 6.05. Financial Information.

          (a) Seller has made available to Buyer all financial information related to the Products, the Purchased Assets and the Assumed Liabilities requested by Buyer, including without limitation the attached Schedule 6.05(a) which shows for each of the last three years and the five months ended May, 2005, units sold and gross revenues for each of the Products; the cost of the Products sold; direct sales, distribution and other operating expenses (including separately shown allocations of costs shared with other business of Seller); the amount of any Assumed Liabilities that are currently capable of being reduced to a fixed dollar amount; and the units and dollar amount by Product of all returns, discounts, rebates and charge-backs for each of the Products. Such financial information was derived from the books and records of Seller and was prepared by Seller in good faith and fairly presents, in all material respects, in accordance with generally accepted accounting principles, such financial information with respect to the Products, Purchased Assets and Assumed Liabilities as of the dates and for the periods shown. There are no discounts or similar arrangements with insurance companies or other payors that are not included in the information shown on Schedule 6.05(a) and in the Contracts listed on Schedule 6.08 (and for which copies of such agreements have been provided to Buyer) that affected the rebates, discounts, chargebacks or the net revenues received by Seller for the Products.

          (b) As of June 30, 2005, the Purchased Assets accounted for 42% of Seller’s year to date revenues through June 30, 2005 and 39% of Seller’s Product Contribution (as defined hereinafter). Seller believes that the Purchased Assets constitute significantly less than half of the Fair Market Value of Seller’s total assets. As of the date of this Agreement and after giving affect to the transactions contemplated hereby, Seller’s business strategy (“Seller’s Business Strategy”) is to focus exclusively on developing and commercializing products that treat diseases and disorders of the central nervous system. Seller will use a substantial portion of the net proceeds from the transactions contemplated hereby to license, acquire and develop products that promote the Seller Business Strategy. For purposes of this Section 6.05(b), the term “Product Contribution” shall mean: net revenues minus cost of goods sold minus specifically identified direct product costs (such as marketing costs but excluding sales expense and corporate overhead), as set forth on Schedule 6.05(b).

          Section 6.06. Title to Purchased Assets; Inventory, Channel. Except as set forth on Schedule 6.06, Seller has good and valid title to all of the Purchased Assets, free and clear of all Encumbrances other than Permitted Encumbrances. There are no contracts, agreements or obligations of any nature that permit any third party to acquire any of the Purchased Assets (other than inventory in the ordinary course). The identity, amounts and expiry dating of the Products included in the Inventory are set forth in Schedule 6.06. Seller is in compliance with all applicable legal requirements regarding the storage, sale and distribution of the Products. There does not exist as of the date hereof, and will not exist at the time of Closing, more than two months of supply of the Products, on an aggregate basis, in the distribution “channels” (of Seller or its distributors or customers) for the Products (assuming sales levels consistent with the past sales levels of the Business). All discounts, rebates, chargebacks, and returns are fully reflected in Schedule 6.05 for the periods shown therein. The currently held ownership rights of Seller with respect to the spray formulations of Nascobal and the rights that Seller is entitled to acquire pursuant to the Nastech APA together represent all ownership, use and marketing rights with respect to the Nascobal spray formulation, including all rights with respect to the applicable IND and/or NDA, the Spray Patent Applications and any patents issued therefrom (including inchoate inventions not yet reduced to practice).

     Section 6.07. Regulatory Issues;

          (a) Except as set forth on Schedule 6.07(a), during the last three (3) years prior to the date of this Agreement, with respect to the Products, neither Seller nor any Affiliate thereof (nor any predecessor owner of rights to the Products or the Business) has received or been subject to: (i) any FDA Form 483’s relating to the Products, (ii) any FDA Notices of Adverse Findings relating to the Products, or (iii) any warning letters or other written correspondence from the FDA concerning the Products, in which the FDA asserted that the operations of Seller were not in compliance with applicable governmental rules or guidelines with respect to the Products. All of the Product Registrations are in full force and effect and all required information and materials relating thereto have been submitted. The Seller is in compliance with all requirements of Code of Federal Regulations Section 21 that are applicable to the Business and the Products.

          (b) During the last three (3) years there has not been any occurrence of any product recall, market withdrawal or replacement, or post-sale warning conducted by or on behalf of Seller (nor any predecessor owner of rights to the Products or the Business) concerning the Products or any product recall, market withdrawal or replacement conducted by or on behalf of any entity as a result of any alleged defect in the Products.

          (c) The information contained in all reports filed with the United States Food & Drug Administration (the “FDA”) by Seller with respect to the Products and the Business is accurate and complete in all material respects and there has been no adverse occurrence, event, effect, study, test, article, report, investigation, or finding that was omitted from such reports, that would require, amendment, modification, updating or supplementing of such reports, or that would require disclosure in a future FDA report (other than current sales and distribution information). To the Knowledge of the Seller, the previous sentence is true with respect to FDA reports filed by prior owners of the Products.

     Section 6.08. Contracts. Schedule 6.08 of the Seller Disclosure Schedule sets forth a complete and correct list of each Contract to which Seller or any Affiliate is a party (or any other Contract to the Knowledge of Seller) that (x) relates to the Business or the research, development, manufacture, marketing, sale or distribution of the Products and (y) (i) restricts or governs in any manner the use, production, distribution, sales or marketing of the Products or conduct of the Business, or (ii) provides for aggregate payments or has a value in excess of $10,000. Seller has provided Buyer with complete and correct copies of all such Contracts. Each of such Contracts is in effect and constitutes a legal, valid and binding agreement of Seller and is enforceable in accordance with its terms; and Seller has performed all of its required obligations under, and is not in violation or breach of or Default under, such Contract and, to the Knowledge of Seller, the other party[ies] to all of such Contracts are not in violation or breach of or under Default thereunder. Except for the $2,000,000.00 obligation relating to the Nastech Asset Purchase Agreement upon satisfaction of certain conditions relating to patent issuances as referred to in Section 3.01(a)(ii), and except as disclosed in Schedule 6.08, there are no remaining obligations of any sort relating to the Products or the Business that are owed to the third parties from which Seller acquired ownership of the Products, irrespective of whether such obligations are being retained by Seller (and Buyer specifically does not assume any such obligation).

     Section 6.09. Intellectual Property Rights. Schedule 6.09(a) contains a true and correct list of all Trademarks (other than Excluded Intellectual Property) owned by Seller and used by Seller in the marketing, manufacture, use, importation, sale and distribution of the Products. Seller represents

and warrants that it owns all rights and interests in the Purchased Intellectual Property and has all right and power to transfer all rights, interest and title to said Purchased Intellectual Property to Buyer pursuant hereto and that Seller has all right and authority to grant to Buyer the license to use the Excluded Intellectual Property granted to Buyer pursuant to the provisions of Section 2.02 above.

The Seller owns and has the exclusive right to use and transfer the trade dress currently used in connection with the packaging and promotion of the Products under these Trademarks. Except as disclosed on Schedule 6.09(a), there have been, and are, no unresolved past or present disputes, demands, or litigation challenging the ownership by Seller or any predecessor of any of the said marks or challenging the validity of any of the marks or the registration thereof. Seller has taken commercially reasonable measures to protect the confidentiality, value and secrecy of the trade secrets and Know-How of Seller in respect to the formulation, manufacture or use of the Products, and no third party has obtained any intellectual property rights with respect to the Purchased Intellectual Property.

          (b) Except as described in Schedule 6.09(b), to the Knowledge of Seller no third party is infringing or misappropriating any of the Purchased Intellectual Property. No third party has gained any rights in the Purchased Intellectual Property as a result of its infringement or misappropriation of the Purchased Intellectual Property.

          (c) Except as set forth on Schedule 6.09(c), there are no outstanding claims asserted in writing against Seller alleging that Seller’s (or its predecessors in the Business) development, marketing, distribution, sale or use of the Products infringes or misappropriates any intellectual property or other proprietary rights of any other Person, and Seller’s development, marketing, manufacture, distribution, sale or use of the Products does not infringe or misappropriate any intellectual property or other proprietary rights of any other Person.

          (d) Seller has not entered into any Contract (i) granting any Person the right to bring infringement actions with respect to, or otherwise to enforce rights with respect to, any of the Purchased Intellectual Property, or (ii) expressly agreeing to indemnify any Person against any charge of infringement of any of the Purchased Intellectual Property.

          (e) Seller has not entered into any Contract (i) granting any Person any right of any nature anywhere in the world with respect to the Business, the Trademarks, the Patent Rights, or the Products other than the agreements included in the contracts listed on Schedule 6.08, or (ii) restricting in any respect the right to sell the Products or conduct the Business anywhere in the world. Except as disclosed in Schedule 6.08 , there are no prior settlements, agreements, or administrative or judicial decisions affecting ownership or validity of the assigned marks or limiting the right of the Seller or any predecessor owner to use or register the marks or to grant this assignment.

          (f) Except as disclosed on Schedule 6.09(f), the Purchased Assets include all intellectual property necessary for Seller to conduct the Business as currently conducted, and no Third Party Intellectual Property is necessary for the conduct of the Business as currently conducted.

          (g) The Product Books and Records include without limitation documents sufficient to establish the Seller’s ownership of and complete chain of title to the Purchased

Intellectual Property, and documents sufficient to establish the first use dates of the Trademarks and the continuous use of the Trademarks since then until the Closing Date, and to complete file histories for U.S. Reg Nos. 1,374,539, No. 2,623,137 and No. 2,157,683.

               (h) In its agreements with third parties, the Seller has taken reasonable measures to protect its rights with respect to the Products throughout the United States and in substantial portions of the world.

     Section 6.10. Litigation. There are no Orders, Actions or Proceedings pending or threatened against, in connection with or relating to (i) the Purchased Assets or the Business as conducted by Seller (or its predecessors in ownership of the Business or the Products), (ii) this Agreement or any Related Agreement or (iii) the transactions contemplated by this Agreement or any Related Agreement.

     Section 6.11. Compliance with Law.

          (a) Except as would not have a Material Adverse Effect, the Business as currently conducted by Seller is in compliance with all applicable Laws.

          (b) Since December 31, 2001, and to the Knowledge of Seller at any time prior to such date, no Governmental or Regulatory Authority has served notice on Seller (or its predecessors in ownership of the Purchased Assets) that the Business as currently conducted by Seller or the Purchased Assets were or are in violation of any Law or the subject of any investigation.

     The Seller possesses, and the Purchased Assets include, (i) all governmental legal rights, permits and authorizations required for the conduct of the Business and the manufacture, marketing, sale and distribution of the Products in the United States and Puerto Rico and (ii) all governmental rights of Seller with respect to the Products in the entire world.

          (a) Each of Buyer and Seller shall to the extent reasonably practicable consult with each other before issuing, and provide each other a reasonable opportunity to review and comment upon, any press release or other public statements with respect to this Agreement, the Related Agreements and the transactions contemplated hereby and thereby, and shall not issue any such press release or make any such public statement prior to such consultation, except as may be

required by applicable law, by court process or by obligations pursuant to any listing agreement with any national securities exchange.

     Section 8.05. Returns, Rebates and Chargebacks.

          (a) (i) Buyer shall not use Seller’s name or NDC number in connection with the sale of the Products after the Closing, and agrees to overlabel the Products with new labels containing Buyer’s NDC number prior to selling any Products after the Closing. Seller shall be financially responsible for all returns, rebates and chargebacks that relate to the Products sold prior to Closing and for any returns that relate to defects in Products included in the Inventory purchased by Buyer pursuant to this Agreement. Buyer shall be financially responsible for returns, rebates and chargebacks relating to Products sold following Closing, except for any returns that relate to defects in Products included in the Inventory purchased by Buyer pursuant to this Agreement.

Notwithstanding the foregoing, Buyer shall be financially responsible for any returns that relate to Products sold prior to the Closing if such returns are received after January 31, 2006.

               (ii) Seller and Buyer will use commercially reasonable efforts in requesting that customers direct all Product returns after the Closing to Buyer. All returned Products received by Seller or Buyer after the Closing will be destroyed by such party, after documentation. For Products returned to Seller at any time after the Closing and for Products returned to Buyer after Closing that are the responsibility of Seller, the destructing party will forward to the other party any necessary accompanying documentation to determine the financially responsible party pursuant to Section 8.05(a)(i) and to assist both parties in compliance with any recordkeeping and/or reporting obligations. If Seller destroys Products for which Buyer was financially responsible, Seller shall bill Buyer for the cost of the destruction. If Buyer destroys Products for which Seller was financially responsible, Buyer shall bill Seller for the cost of the destruction. Each such invoice shall set forth the number of units processed, together with such other information as shall be necessary to support the invoice and to assist both parties in compliance with any recordkeeping and/or reporting obligations. Buyer and Seller shall, within thirty (30) days of its receipt of invoice, pay the other party for the full invoiced amount of such costs. The party financially responsible pursuant to Section 8.05(a)(i) for any returned Product shall have the responsibility for issuing a proper credit to the returning customers, or otherwise properly compensating such customers. For purposes of this Section 8.05(a)(ii), the dollar value of returned Products paid or credited for by Seller or Buyer, as applicable, shall be determined in accordance with such party’s then current returned goods policy.

          (b) Seller shall process and be financially responsible for all chargeback claims and related administrative service fees for the Products with a chargeback invoice dated (i.e., the date of sale from the wholesaler to the wholesaler customer, subsequently referred to as the “Activity Date”) prior to the Closing Date. Buyer shall process and be financially liable for all chargeback claims and related administrative service fees with an Activity Date subsequent to such date. Notwithstanding the foregoing, the parties acknowledge that the VA National Acquisition Center must approve the removal of the Products from Seller’s Federal Supply Schedule (“FSS”) before the responsibility of processing such chargebacks is transferred from Seller to Buyer. Accordingly, in the event such approval is not obtained prior to the Closing Date, Seller shall continue to be responsible for processing the FSS chargebacks and related administrative service fees on Buyer’s behalf, and Buyer shall reimburse Seller for same within thirty (30) days of receipt of invoices that describe the requested payments in reasonable detail. Buyer and Seller agree that (a) Seller’s financial liability for such transition chargebacks and related administrative service fees shall be limited to those commercial customers with which Seller has chargeback obligations as of the Closing, and (b) any such chargebacks and related administrative service fees issued by Seller shall be made on the terms and conditions comparable to Seller’s chargeback obligations as of the Closing with respect to each such commercial customer and shall be based on the terms of Seller’s agreement with such customer as of the Closing. Buyer and Seller agree that Seller’s financial liability for processing and administrating chargeback claims and related administrative service fees shall terminate on the date that is thirty (30) days after the Closing Date. To the extent that Seller is required to process or administrate any such matters, Buyer shall, within thirty (30) days of its receipt

of an invoice from Seller setting forth Seller’s reasonable costs relating thereto, pay Seller for the full invoiced amount.

     Section 8.06. Multi-Product Contracts. Schedule 8.06 of the Seller Disclosure Schedule sets forth a complete and correct list of each Contract to which Seller is a party and pursuant to which Seller sells any of the Products, together with other pharmaceutical products of Seller, to a third party (the “Multi-Product Contracts”). Seller has made available to Buyer copies of all Multi-Product Contracts; provided, that such copies may have been redacted only to prevent disclosure of information not related to any of the Products or the Business. From and after the Closing Date, (i) Buyer shall honor and perform the Product delivery obligations of Seller under and pursuant to each Multi-Product Contract with respect only to supplying the Products to the applicable third party after the Closing Date and (ii) Seller shall honor and perform the administrative obligation of processing and issuing chargeback claims and related administrative service fees applicable to the Products sold by Buyer after Closing under and pursuant to the Multi-Product Contracts, both until such time as Seller has terminated each such Multi-Product Contract. Buyer shall be entitled to all proceeds of sales of Products made pursuant to the Multi-Product Contracts after the Closing Date. Seller agrees that after the date hereof it will not take any action with respect to any Multi-Product Contract that would extend the term of such Multi-Product Contract with respect to the Products, fail to take any action with respect to any Multi-Product Contract that would terminate such Multi-Product Contract with respect to the Products, create or agree to any additional obligations with respect to the Products, including entering into any new Multi-Product Contracts that include the sale of Product, or otherwise adversely affect Buyer, without the prior written consent of Buyer, although Seller may enter into separate agreements with such third parties that do not contain any provisions relating to the Products.

     Section 8.07. Bulk Transfer Laws. Buyer hereby waives compliance by Seller with the provisions of any so-called “bulk transfer law” of any jurisdiction in connection with the sale of the Purchased Assets to Buyer.

     Section 8.08. Further Assurances.

          (a) On and after the Closing Date, Seller shall, from time to time, at the request of Buyer, execute and deliver, or cause to be executed and delivered, such other instruments of conveyance and transfer and take such other actions as Buyer may reasonably request, in order to more effectively consummate the transactions contemplated hereby and in the Related Agreements and to vest in Buyer good and marketable title to the Purchased Assets (including assistance in the collection or reduction to possession of any of the Purchased Assets). Without limiting the generality of the foregoing, Seller agrees that, in the event it transfers any technology or intellectual property related to the Products, it will, as a condition to any such transfer, obtain the agreement from any such transferee that such transferee will not import or otherwise sell or transfer any products based on or containing such technology or intellectual property.

          (b) On and after the Closing Date, Buyer shall, from time to time, at the request of Seller, take such actions as Seller may reasonably request, in order to more effectively consummate the transactions contemplated hereby and in the Related Agreements, including Buyer’s assumption of the Assumed Liabilities to the limited extent provided herein.

     Section 8.09. No Solicitation. Seller and its Affiliates, officers, directors, representatives shall immediately cease any discussions or negotiations with any parties with respect to any Third

Party Acquisition Proposal. Seller also agrees promptly to request each person that has heretofore executed a confidentiality agreement in connection with its consideration of acquiring (whether by merger, acquisition of stock or assets or otherwise) all or part of the Purchased Assets, if any, to return all confidential information heretofore furnished to such person by or on behalf of Seller and, if requested by Buyer, to enforce such person’s obligation to do so. Neither Seller nor its Affiliates shall, and neither Seller nor its Affiliates shall authorize or permit any of their respective officers, directors or representatives to, directly or indirectly, encourage, solicit, participate in, continue, or initiate discussions or negotiations with or provide any information to or enter into any agreement with any person or group (other than Buyer or any designees of Buyer) concerning any Third Party Acquisition Proposal.

     Section 8.10. Insurance. For a period of three (3) years following the Closing, Seller will maintain insurance policies covering the conduct of the Business prior to the Closing, including but not limited to product liability insurance relating to the Products sold by Seller (collectively, the “Seller Insurance Policies”), which are of the type and in amounts customarily carried by Persons conducting businesses similar to the Business, or Seller will put in place substantially equivalent “tail” coverage and maintain it for at least three (3) years following the Closing.

     Section 8.11. Post-Closing Assistance. Following Closing, Seller shall forward all inquiries regarding purchasing the Products from current or potential customers of the Business that it receives to the Buyer and provide such third parties with the names and contact information of Buyer customer representatives provided to Seller by Buyer at or following the Closing. Seller shall provide reasonable assistance to Buyer in alerting current or potential customers of the Business of the change in Product provider, including issuance of written notices to current customers, and FDA informing them of the change.

     Section 8.12. Special Obligation Regarding Materiality Qualifications. Certain of the representations and warranties of the parties contained in Articles Six and Seven of this Agreement are qualified by references such as “Material Adverse Effect,” “Buyer Adverse Effect” or other materiality limitations. It is the specific intent of the parties that such provisions shall not affect the obligations of the parties with respect to the representations and warranties. Therefore, Seller covenants and agrees that if a representation or warranty of Seller would have been a misrepresentation or false or would have been breached or in breach by an event, circumstance, occurrence or state of facts if the representation or warranty had not been qualified by the materiality reference, then Buyer and the Buyer Indemnitees shall be entitled to indemnity under Section 11.02(a) hereof as fully and completely as if the materiality qualifier were not included in the representation. Similarly, Buyer covenants and agrees that if a representation or warranty of Buyer would have been a misrepresentation or false or would have been breached by an event, circumstance, occurrence or state of facts if the representation or warranty had not been qualified by the materiality reference, then Seller and the Seller Indemnitees shall be entitled to indemnity under Section 11.02(b) hereof as fully and completely as if the materiality qualifier were not included in the representation.

     Section 10.02. No Actions or Proceedings. No Orders prohibiting the transactions contemplated by this Agreement or the Related Agreements shall have been instituted and not settled or otherwise terminated. No Law shall have been enacted, entered, promulgated or enforced by any Governmental or Regulatory Authority that is in effect and has the effect of making the purchase and sale of the Purchased Assets illegal or otherwise prohibiting the consummation of such purchase and sale or the other transactions contemplated by this Agreement or the Related Agreements.

     Section 10.03. Consents. All Seller Governmental Consents and Seller Third Party Consents shall have been obtained or made, as the case may be.

     Section 10.04. Related Agreements. The other parties thereto shall have executed and delivered to Buyer all of the Related Agreements.

     Section 10.05. Absence of Material Adverse Effects. There shall have been no change in the Business, financial condition, or results of operations of the Seller since December 31, 2004, which has had a Material Adverse Effect or reasonably could be expected to have a Material Adverse Effect.

ARTICLE XI

INDEMNIFICATION

     Section 11.01. Survival of Representations, Warranties, Covenants, Etc. The representations and warranties and covenants and agreements of Seller or Buyer contained in this Agreement shall survive Closing and terminate 18 months following the Closing Date (except for (i) the

representations and warranties contained in Sections 6.07(c) and 6.10, all of which shall survive for a period of four (4) years from Closing, (ii) the representations and warranties contained in Sections 6.01, 6.06, 6.07(a), 6.07(b), 6.09, 7.01 and 7.02, all of which shall survive until expiration of the applicable statute of limitations, (iii) the representations and warranties contained in Sections 6.02 and 6.05(b) shall survive without limitation, irrespective of the time following Closing that elapses before a claim may arise, and (iv) the obligations undertaken in the covenants contained herein which by their terms provide for a longer period of time (such as Section 2.04), which covenants shall survive for the respective periods provided in this Agreement). So long as an Indemnified Party gives an Indemnification Claim Notice for such a claim on or before the applicable expiration date, such Indemnified Party shall be entitled to pursue its rights to indemnification with respect to such claim.

     Section 11.02. Indemnification.

          (a) By Seller. Subject to Sections 11.01 and 11.03, from and after the Closing, Seller shall indemnify, reimburse, defend and hold harmless Buyer, its Affiliates and owners (other than any of its members and lenders in their capacities as such) and their respective officers, directors, employees, agents, successors and assigns (collectively, the “Buyer Indemnitees”) from and against any and all losses, damages, fines, penalties, judgments, lawsuits, deficiencies, claims, expenses, and out-of-pocket costs, (including reasonable fees and disbursements of attorneys and other professionals, including third-party consultants and, to the extent allowable at Law, medical monitoring costs and expenses) of every kind and nature (collectively, “Damages”) incurred in connection with, arising out of, resulting from or incident to (i) any breach of a representation or warranty of Seller made in this Agreement or any Related Agreement, (ii) any breach of any covenant or agreement of Seller in this Agreement or any Related Agreement, (iii) any Excluded Liabilities, and (iv) the conduct of the Business and/or the use of the Purchased Assets prior to the Closing. For purposes of determining whether a representation or warranty of Seller has been breached, and the amount of any Damages attributable to any such breach, such determinations shall be made without giving any effect to any materiality qualifications in the representations and warranties including without limitation references to “Material Adverse Effect” or “in all material respects,” and all such materiality qualifications shall be disregarded. In other words, it is the specific and expressed intent of the parties that if a representation or warranty of Seller contained in this Agreement that is modified by Material Adverse Effect or words of similar effect would have been untrue or breached by or due to an occurrence, event or circumstance if such representation or warranty were not so qualified, then because all such materiality qualifications are disregarded for purposes of indemnification, the representation or warranty shall be deem to have been breached and Buyer shall be entitled to indemnification pursuant to this Section 11.02(a). For purposes of clarification, the modification of Affiliates and owners contained in the parenthetical on the second and third line of this Section 11.02(a) is intended to provide that the indemnification hereunder are not intended to extend to claims by a member or lender of Buyer for indirect damages resulting from Damages incurred by Buyer due to a misrepresentation or breach by Seller to the extent that such member or lender is affected solely because of their investment in or loan to the Buyer (such as diminished value of the member’s investment in Buyer or a higher risk of collection of a loan for the lender, respectively) because these items are the subject of indemnification of Buyer by Seller hereunder; provided however, the members or lenders of Buyer shall be entitled to indemnification hereunder for Damages they directly incur due to a misrepresentation or breach by Seller (such as being named in a Third Party Claim).

          (b) By Buyer. Subject to Sections 11.01 and 11.03, from and after the Closing, Buyer shall indemnify, reimburse, defend and hold harmless Seller, its Affiliates and owners (other than any of its shareholders and lenders in their capacities as such) and their respective officers, directors, employees, agents, successors and assigns (collectively, the “Seller Indemnitees”) from and against any and all Damages incurred in connection with, arising out of, resulting from or incident to (i) any breach of a representation or warranty of Buyer made in this Agreement or any Related Agreement, (ii) any breach of any covenant or agreement of Buyer in this Agreement or any Related Agreement, (iii) any Assumed Liabilities, and (iv) the conduct of the Business and/or the use of the Purchased Assets by Buyer or its successors and assigns after the Closing, unless such conduct or use, or the matter giving rise to the claim, relates to a breach of a representation, warranty or covenant of Seller hereunder or is subject to indemnification by Seller under Section 11.02(a) (or would be subject but for the expiration of indemnities under Section 11.01 or the effect of the Buyer Deductible or the Buyer Cap). For purposes of determining whether a representation or warranty of Buyer has been breached, and the amount of any Damages attributable to any such breach, such determinations shall be made without giving any effect to any materiality qualifications in the representations and warranties including without limitation references to “Buyer Adverse Effect” or “in all material respects,” and all such materiality qualifications shall be disregarded. In other words, it is the specific and expressed intent of the parties that if a representation or warranty of Buyer contained in this Agreement that is modified by Buyer Adverse Effect or words of similar effect would have been breached by or due to an occurrence, event or circumstance if such representation or warranty were not so qualified, then because all such materiality qualifications are disregarded, the representation or warranty shall be deemed to have been breached and Seller shall be entitled to indemnification pursuant to this Section 11.02(b). For purposes of clarification, the modification of Affiliates and owners contained in the parenthetical on the second and third line of this Section 11.02(b) is intended to provide that the indemnification hereunder are not intended to extend to claims by a member or lender of Seller for indirect damages resulting from Damages incurred by Buyer due to a misrepresentation or breach by Buyer to the extent that such shareholder or lender is affected solely because of their investment in or loan to the Seller (such as diminished value of the shareholder’s investment in Buyer or a higher risk of collection of a loan for the lender, respectively) because these items are the subject of indemnification of Seller by Buyer hereunder; provided however, the members or lenders of Seller shall be entitled to indemnification hereunder for Damages they directly incur due to a misrepresentation or breach by Buyer (such as being named in a Third Party Claim).

          (c) Procedure for Claims. The indemnified party shall give the indemnifying party prompt written Notice (an “Indemnification Claim Notice”) of any Damages or with respect to which such indemnified party intends to base a request for indemnification under Section 11.02(a) or Section 11.02(b). Failure to promptly give any such Indemnification Claim Notice shall not constitute a waiver of any right to indemnification or reduce in any way the indemnification available hereunder, except to the extent such failure to notify directly increases the amount to be indemnified hereunder. Each Indemnification Claim Notice must contain a description of the claim and the nature and amount of such Damages (to the extent that the nature and amount of such Damages are known at such time). The indemnified party shall furnish promptly to the indemnifying party copies of all papers and official documents received in respect of any Damages. All indemnification claims in respect of a party, its Affiliates or their respective directors, officers, employees and agents (collectively, the “Indemnitees” and each an “Indemnitee”) shall be made solely by such party (or their respective counsel) to this Agreement (the “Indemnified Party”).

          (d) Third Party Claims. The obligations of an indemnifying party under this Section 11.02 with respect to Damages arising from claims of any third party that are subject to indemnification as provided for in Section 11.02(a) or Section 11.02(b) (a “Third Party Claim”) shall be governed by and be contingent upon the following additional terms and conditions:

               (i) At its option, the indemnifying party may assume the defense of any Third Party Claim by giving written Notice to the Indemnified Party within thirty (30) days after the indemnifying party’s receipt of an Indemnification Claim Notice. The assumption of the defense of a Third Party Claim by the indemnifying party shall be construed as an acknowledgment that the indemnifying party is liable to indemnify any Indemnitee in respect of the Third Party Claim, and it shall constitute a waiver by the indemnifying party of any defenses it may assert against any Indemnitee’s claim for indemnification. If the indemnifying party disputes liability for the indemnification it may not assume control of the litigation; however, it may nonetheless employ counsel of its own at its own expense and participate in the defense of the Third Party Claim; provided however, all final decisions regarding the Third Party Claim shall be made by the party subject to the Third Party Claim. Upon assuming the defense of a Third Party Claim, the indemnifying party may appoint as lead counsel in the defense of the Third Party Claim any legal counsel reasonably selected by the indemnifying party; provided, however, that in the event that a conflict of interest arises between the indemnifying party and the Indemnified Party such that such legal counsel cannot represent both the indemnifying party and the Indemnified Party, the Indemnified Party may retain its own legal counsel at the expense of the indemnifying party, and the indemnifying party and its counsel shall cooperate with the Indemnified Party and its counsel as may be reasonably requested. In the event the indemnifying party assumes the defense of a Third Party Claim, the Indemnified Party shall promptly deliver to the indemnifying party all original notices and documents (including court papers) received by any Indemnitee in connection with the Third Party Claim. Except as set forth above, should the indemnifying party assume the defense of a Third Party Claim, the indemnifying party shall not be liable to the Indemnified Party or any other Indemnitee for any legal expenses subsequently incurred by such Indemnified Party or other Indemnitee in connection with the analysis, defense or settlement of the Third Party Claim. Notwithstanding the foregoing, if the Third Party Claim alleges any criminal conduct or any other allegation that if consented to or determined adversely will adversely affect the Indemnified Party (including without limitation, the Business or the Products), seeks damages in excess of the Cap Amount below, or seeks any form of injunctive relief against the Indemnified Party, the Indemnified Party shall control the litigation if it chooses, and in any event, no settlement of the Third Party Claim may include any admission of wrongdoing or accept any curtailment of the Business or otherwise affect Buyer’s rights with respect to the Product or the development or commercialization thereof, or otherwise affect the business or assets of Buyer without its written consent. In any of the circumstances referred to in the immediately preceding sentence, the reasonable legal fees and costs of the Indemnified Party in such event shall be included in the computation of Damages subject to indemnity hereunder.

               (ii) Without limiting Section 11.02(d)(i), any Indemnitee shall be entitled to participate in, but not control, the defense of such Third Party Claim and to employ counsel of its choice for such purpose; provided, however, that such employment shall be at the Indemnitee’s own expense, except as provided in Section 11.02(d)(i), unless (A) the employment thereof has been specifically authorized by the indemnifying party in writing, or (B) the indemnifying party has failed to assume the defense and employ counsel in accordance with Section 11.02(d)(i) (in which case the Indemnified Party shall control the defense).

               (iii) With respect to any Damages relating solely to the payment of money damages in connection with a Third Party Claim and that will not result in the Indemnitee’s or the Indemnified Party’s becoming subject to injunctive or other relief or otherwise adversely affect the business or reputation of the Indemnitee or the Indemnified Party in any manner, and as to which the indemnifying party shall have acknowledged in writing the obligation to indemnify the Indemnitee hereunder, the indemnifying party shall have the sole right to consent to the entry of any judgment, enter into any settlement or otherwise dispose of such Damages, on such terms as the indemnifying party, in its sole discretion, shall deem appropriate, provided that, as a result of or in connection with any such settlement each Indemnitee or Indemnified Party shall receive a full release with respect to such claim. With respect to all other Damages in connection with Third Party Claims, where the indemnifying party has assumed the defense of the Third Party Claim in accordance with Section 11.02(d)(i), the indemnifying party shall have authority to consent to the entry of any judgment, enter into any settlement or otherwise dispose of such Damages; provided, however, that it obtains the prior written consent of the Indemnified Party (which consent shall not be unreasonably withheld, delayed or conditioned). The indemnifying party shall not be liable for any settlement or other disposition of Damages by an Indemnitee or Indemnified Party that is reached without the written consent of the indemnifying party; provided however, if the indemnifying party refuses to consent to such settlement or other disposition of Damages and there is ultimately a judicial determination of other disposition of the matter resulting in higher Damages, the indemnifying party shall be liable for such additional Damages without regard to the Cap Amount defined below. Regardless of whether the indemnifying party chooses to defend or prosecute any Third Party Claim, no Indemnitee or Indemnified Party shall admit any liability with respect to, or settle, compromise or discharge, any Third Party Claim without the prior written consent of the indemnifying party; subject to the proviso in the immediately preceding sentence.

               (iv) Regardless of whether the indemnifying party chooses to defend or prosecute any Third Party Claim, the Indemnified Party and each indemnifying party shall, and shall cause each other Indemnitee or Affiliate of any such indemnifying party, as applicable, to, cooperate in the defense or prosecution thereof and shall furnish such records, information and testimony, provide such witnesses and attend such conferences, discovery proceedings, hearings, trials and appeals as may be reasonably requested in connection therewith. Such cooperation shall include access during normal business hours afforded to the indemnifying party or Indemnified Party, as applicable, to, and reasonable retention by each such Person of, records and information that are reasonably relevant to such Third Party Claim, and making each such Person and other employees and agents available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder, and the indemnifying party shall reimburse each such Person for all its reasonable out-of-pocket expenses in connection therewith.

     Section 11.03. Limitations.

          (a) In no event shall Seller be liable for any Damages pursuant to a claim based upon a representation or warranty or covenant or agreement pursuant to Section 11.02(a) (“Buyer Eligible Claim”), (i) unless and until the aggregate amount of all Buyer Eligible Claims exceeds of $350,000 (the “Buyer Deductible”), in which case Seller shall be liable only for Damages in excess of the Buyer Deductible, and then (ii) not for any amount in excess of the aggregate of the Consideration paid and the Assumed Liabilities assumed by Buyer under Section 4.01 (the “Buyer Cap Amount”) for all Buyer Eligible Claims made under Section 11.02(a), in the aggregate. For purposes of determining the Buyer Cap Amount, the term Assumed Liabilities as used in this Section 11.03 shall exclude the Nastech Payment, unless, and until, Buyer has paid the Nastech Payment.

Notwithstanding any other provision hereof, the Buyer Deductible and the Buyer Cap Amount shall not apply to breaches of the following Sections by Seller: 2.04, 6.01, 6.02, 6.06, 6.07, 6.13, or to claims under Sections 11.02(a)(ii) and 11.02(a)(iii). With respect to claims relating to breaches of the representations and warranties contained in Sections 6.02 and 6.05(b), (i) there expressly shall be no limitations or reductions of any nature whether pursuant to this Section 11.03(a), 11.03(c), 11.03(d), the last sentence of Section 11.02(a), or otherwise and all of such limitations shall be deemed inapplicable and (ii) irrespective of any provisions of Section 11.02(d) that may limit or restrict Buyer’s entitlement to separate counsel or to indemnification for all legal costs, the Buyer shall be entitled to full indemnification of all Damages and all other losses of any nature and costs of legal fees and other costs and expenses in any respect relating to a breach or alleged breach of the representations and warranties of Seller set forth in Sections 6.02 and 6.05(b).

          (b) In no event shall Buyer be liable for any Damages pursuant to a claim based upon a representation or warranty or covenant or agreement pursuant to Section 11.02(b) (“Seller Eligible Claim”), (i) unless and until the aggregate amount of all Seller Eligible Claims exceeds of $350,000 (the “Seller Deductible”), in which case Buyer shall be liable only for Damages in excess of the Seller Deductible, and then (ii) not for any amount in excess of $1,500,000 (the “Seller Cap Amount”) for all Eligible Claims made under Section 11.02(b), in the aggregate. Notwithstanding any other provision hereof, the Seller Deductible and the Seller Cap Amount shall not apply to breaches of the following Sections by Buyer: 7.01, 7.02 and 7.06, or to claims under Sections 11.02(b)(ii), 11.02(b)(iii) and 11.02(b)(iv) (except that claims under Section 11.02(b)(iv) for attorneys’ fees and related litigation costs shall be subject to the Seller Cap Amount).

          (c) The amount of any Damages for which indemnification is provided under this Article XI shall be net of any amounts recovered by the Indemnified Party under insurance policies with respect to such Damages, after giving effect to any premium adjustments related to such Damages, provided that an Indemnified Party shall have no obligation to seek recovery under any insurance policies prior to seeking recovery from the indemnifying party. For purposes of clarification, in the event there is a reduction in Damages payable hereunder by a party due to an insurance recovery, the amount of the insurance recovery that will be used to reduce the Damages claim shall be offset by the increase in insurance premiums due to the incurrence of the insurance claim. If there is no reduction of the amount of Damages payable because there is either no insurance recovery or the recovery must be repaid from the Damages paid pursuant to this Article 11, then Damages shall not be increased by any increase in insurance premiums relating to the event or occurrence that gave rise to the Damages claim.

          (d) Buyer and Seller agree that the sole and exclusive remedy for money damages for any matters relating to this Agreement, the Related Agreements and any certificate or instrument delivered pursuant hereto or thereto shall be the rights to indemnification set forth in this Article XI; provided however, each party shall be entitled to seek such injunctive or other non-monetary equitable relief as may be appropriate with respect to breaches of covenants contained herein.

     Section 11.04. Indemnification Payments Made to Buyer. Any payments required of Seller to Buyer pursuant to the terms of this Agreement (whether for indemnification or otherwise) shall be paid into the Buyer’s bank account maintained under a control account structure with its primary lender Fortress Credit Corp. The Buyer and Fortress Credit Corp. shall by joint instruction to Seller provide the relevant account information for wire transfer or other delivery of such payments and

keep such account information up to date as appropriate following the closing, or by joint instruction provide notice to Seller that this Section 11.04 is no longer applicable.

ARTICLE XII

TERMINATION AND ABANDONMENT

     Section 12.01. Methods of Termination. Prior to the Closing, the transactions contemplated herein may be terminated and/or abandoned at any time:

          (a) by mutual written agreement of Seller and Buyer;

          (b) by Seller if the Closing shall not have occurred by December 31, 2005 (the “Termination Date”); provided, however, that the right to terminate this Agreement pursuant to this Section 12.01(b) shall not be available to Seller if its failure to perform any of its obligations under this Agreement or any Related Agreement results in the failure of the Closing to occur by such time;

          (c) by Buyer if the Closing shall not have occurred by the Termination Date; provided, however, that the right to terminate this Agreement pursuant to this Section 12.01(c) shall not be available to Buyer if its failure to perform in all material respects any of its obligations under this Agreement or any Related Agreement results in the failure of the Closing to occur by such time;

          (d) by either Seller or Buyer if there shall be in effect any Law that prohibits the Closing or if the Closing would violate any non-appealable Order;

          (e) by either Seller or Buyer if any of the conditions to their obligations to Close pursuant to Articles VIII or IX, respectively, are not met or waived on or before the Termination Date; or

          (f) by either Seller or Buyer if the other party has breached any material obligation (including but not limited to a breach of representation or warranty herein) hereunder that remains uncured for a period of thirty (30) days following the delivery of Notice to the breaching party, unless such breach is not capable of cure, in which event the non-breaching party may terminate immediately.

          (g) by Buyer if Seller shall have willfully and materially breached its obligations under Section 8.11.

     Section 12.02. Procedure upon Termination. In the event of termination and abandonment pursuant to Section 12.01, written Notice thereof shall forthwith be given to the other party, and the transactions contemplated by this Agreement shall be terminated and abandoned, without further action by the parties hereto. If the transactions contemplated by this Agreement are terminated and/or abandoned as provided herein:

          (a) each party, if requested, will redeliver all documents, work papers and other material of the other party and its Affiliates relating to the transactions contemplated hereby, whether so obtained before or after the execution hereof, to the party furnishing the same; and

          (b) no party hereto and none of its directors, officers, stockholders, Affiliates or Controlling Persons shall have any further liability or obligation to any other party to this Agreement,

except that nothing in this Section 12.02 shall prejudice any rights, claims, or causes of action that may have accrued hereunder or with respect hereto prior to the date of such termination, including for breach of this Agreement (whether based upon the termination or otherwise).

     Section 12.03. Specific Performance. The parties acknowledge that the transactions contemplated hereby are unique and specifically identifiable. Accordingly, the parties further agree and stipulate that, if the Closing does not occur because of the willful failure of Seller, on the one hand, or Buyer, on the other hand, to perform their respective obligations hereunder, (a) monetary damages and any other remedy at law will not be adequate, (b) the non-defaulting party shall be entitled to specific performance as the remedy for such breach, (c) each party agrees to waive any objection to the remedy of specific performance, (d) each party agrees that the granting of specific performance by any court will not be deemed to be harsh or oppressive to the party who is ordered specifically to perform its obligations under this Agreement and (e) in connection with any action for specific performance, the prevailing party shall be entitled to reasonable attorneys’ fees and other costs of prosecuting or defending such action. The right to seek specific performance hereunder shall not preclude any party to seek any other remedy at law or in equity.

     Section 13.09. Governing Law; Venue. This Agreement shall be deemed to be made in and in all respects shall be interpreted, construed and governed by and in accordance with the law of the state of California without regard to the conflict of applicable law principles thereof.

Each of the parties hereto further agrees that, to the fullest extent permitted by applicable Law, service of any process, summons, notice or document by U.S. registered mail to such person’s respective address set forth above shall be effective service of process for any action, suit or proceeding with respect to any matters to which it has submitted to jurisdiction as set forth above in the immediately preceding sentence. Each of the parties hereto irrevocably and unconditionally waives (and agrees not to plead or claim) any objection to the laying of venue of any action, suit or proceeding arising out of this Agreement or the transactions contemplated hereby in such courts, or that any such action, suit or proceeding brought in any such court has been brought in an inconvenient forum.

     Section 13.10. Equitable Relief. The parties agree that irreparable damage would occur and that the parties would not have any adequate remedy at law in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached.

Alameda and the United States District Court for the Northern District of California, this being in addition to any other remedy to which they are entitled at law or in equity
