ASSET PURCHASE AGREEMENT

This Asset Purchase Agreement is entered into as of October 7, 2005 (the “Effective Date”), by and between: DISCOVERY PARTNERS INTERNATIONAL, INC., a Delaware corporation (the “Seller”), and IRORI DISCOVERY, INC., a California corporation (the “Purchaser”). Certain capitalized terms used in this Agreement are defined in Exhibit A.

Recitals

The Seller wishes to provide for the sale of certain of the Seller's assets relating to the Seller's Discovery Systems Division (the “Business”) to the Purchaser on the terms set forth in this Agreement.

AGREEMENT

The parties to this Agreement, intending to be legally bound, agree as follows:

1. SALE OF ASSETS; RELATED TRANSACTIONS.

1.1 Sale of Assets. The Seller shall cause to be sold, assigned, transferred, conveyed and delivered to the Purchaser, at the Closing (as defined below), good and valid title to the Assets (as defined below), free of any Encumbrances, on the terms and subject to the conditions set forth in this Agreement. For purposes of this Agreement, “Assets” shall mean and include those assets related to the Business identified on Exhibit B; provided, however, that to the extent that any assets owned by the Seller on the Effective Date are necessary for the operation of the Business as currently operated by the Seller are not included on Exhibit B (the “Omitted Assets” and each an “Omitted Asset” ), the Seller will transfer, or if such transfer is not practicable, the parties will make good faith efforts to license or otherwise make generally available to the Purchaser all of such Omitted Assets, without any payment or other obligations imposed upon the Purchaser if such payment or other obligation is de minimis. Notwithstanding the foregoing: (i) the Omitted Assets shall not include any cash or licenses to commercially available software unless such software is expressly listed on Exhibit B or is located on any computer or other equipment transferred to the Purchaser as an Asset and (ii) the Omitted Assets shall not include any asset of the Seller not otherwise listed on Exhibit B if such transfer, license or availability of such Omitted Asset would impair the operations of the Seller.

1.2 Purchase Price.

(a) As consideration for the sale of the Assets to the Purchaser:

(i) at the Closing, the Purchaser shall pay to the Seller, in cash, a total of $1,500,000 (the “Closing Purchase Price”), which amount shall be subject to adjustment pursuant to Section 1.3; and

(ii) at the Closing, the Purchaser shall assume the Assumed Liabilities by delivering to the Seller an Assignment and Assumption Agreement in substantially the

form of Exhibit C (the “Assumption Agreement”). Purchaser shall not assume any liabilities of Seller pursuant hereto, other than the Assumed Liabilities.

(b) For purposes of this Agreement “Assumed Liabilities” shall mean only the following liabilities of the Seller (and specifically excluding the liabilities set forth on Schedule 1.2(b)):

(i) all accounts payable and accrued liabilities of the Seller relating to the Business arising after August 31, 2005;

(ii) all obligations, duties and liabilities of the Seller continuing after the Closing under the Contracts identified on Exhibit D to this Agreement (the “Assumed Contracts”), which become due and payable or are required to be performed after the Closing Date, except to the extent arising from any breach or default occurring prior to the Closing Date;

(iii) all liabilities expressly listed or described on Schedule 1.2(b)(iii);

(iv) all liabilities related to the Assets to the extent arising from or related to any facts or circumstances occurring after the Closing Date;

(v) the obligations of the Seller for existing and future field service and warranty expenses and liabilities for all Business products set forth on Schedule 1.2(b)(v) (the “Business Products”), including the Universal Stores sold to the Seller and Sanofi-Aventis;

(vi) the obligations of the Seller for non-salary marketing of Business Products, customer sales and support expenses for the Business that relate directly to the Assets, including, but not limited to, commitments for trade shows;

(vii) the obligations of the Seller set forth on Schedule 1.2(b)(vii) for non-salary research and development expenses for Business Products, including, but not limited to, commitments for parts and materials, license fees, and consulting services to be used in the Business that relate directly to the Assets.

1.3 Purchase Price Adjustment.

(a) Within 60 days after the Closing, the Seller shall prepare and deliver to the Purchaser (i) a balance sheet for the Business as of June 30, 2005, August 31, 2005, and the Closing Date, (ii) a cash flow statement for the Business for the period from September 1, 2005 through the Closing Date (collectively, the “Business Financial Information”), and (iii) a calculation of the Adjusted Purchase Price. In the event that the Adjusted Purchase Price is greater than the Closing Purchase Price, the amount of such difference shall be paid by Purchaser to Seller. In the event that the Closing Purchase Price is greater than the Adjusted Purchase Price, the amount of such difference shall be paid by the Seller to Purchaser.

(b) If within 15 days following delivery of the Business Financial Information and calculation of Adjusted Purchase Price, the Purchaser has not given the Seller written notice of its objection to the calculation of Adjusted Purchase Price (which notice shall state the basis of the Purchaser's objection, such notice being referred to herein as the “Dispute Notice”), then the calculation of Adjusted Purchase Price shall be final and binding on the parties, and the Purchaser or Seller, as the case may be, shall make the payment to the other party contemplated in Section 1.3(a).

(c) If the Purchaser delivers to the Seller the Dispute Notice, the Purchaser and the Seller shall attempt to resolve in good faith any disputed items during the 15-day period subsequent to the Seller's receipt of the Dispute Notice. If, after such 15-day period, the Seller and the Purchaser cannot resolve such dispute, the unresolved disputed items will be referred to a nationally-recognized firm of certified public accountants as the Seller and the Purchaser may designate (the “Accounting Firm”). Such referral shall be in the form of written statements of position by the Seller and the Purchaser to the Accounting Firm, with each party having the opportunity to respond to such written statements and any requests for statements or information that may be made by the Accounting Firm. The Accounting Firm shall as promptly as practicable (and in any event within 30 days) make a final determination of the Business Financial Information, which determination shall be made on the same basis and applying the same accounting principles, policies and practices that were used in preparing the Financial Statements (as defined in Section 2.14 below), and calculation of the Adjusted Purchase Price which shall be final and binding on the parties. Each of the Seller and the Purchaser shall provide the Accounting Firm with all information and documentation that the Accounting Firm reasonably requests in connection with its review of the disputed items. The fees and expenses incurred by the Accounting Firm in conducting the audit of the Business Financial Information shall be borne (i) by the Purchaser, in the event that the Purchase Price calculated using the Final Statement is greater than the Purchase Price as determined using the original Business Financial Information (the “Original Purchase Price”) by an amount equal to or greater than five percent (5%) of the Original Purchase Price, (ii) by the Seller, in the event that the Purchase Price calculated using the Final Statement is less than the Original Purchase Price by an amount equal to or greater than five percent (5%) of the Original Purchase Price, or (iii) in all other circumstances, fifty percent (50%) by the Seller and fifty percent (50%) by the Purchaser.

(d) All payments required to be made in accordance with this Section 1.3 shall be made within ten days after the calculation of the Adjusted Purchase Price becomes final and binding on the parties pursuant to this Section 1.3.

1.4 Sales Taxes. Any sales taxes, use taxes, transfer taxes, documentary charges, recording fees or similar taxes, charges, fees or expenses that may become payable in connection with the sale of the Assets to the Purchaser or in connection with any of the other Transactions shall be borne by the Purchaser.

1.5 Allocation. The parties hereto intend that the purchase of the Assets be treated as a taxable transaction for federal and state income tax purposes. Within 60 days of the Closing, the Seller shall deliver a proposed allocation of the consideration referred to in Section 1.2, as adjusted pursuant to Section 1.3, among the Assets (the “Allocation”), which Allocation shall be

reasonably acceptable to the Purchaser and determined in a manner consistent with Section 1060 of the Internal Revenue Code and the Treasury Regulations thereunder. The Allocation shall be conclusive and binding upon the Purchaser and the Seller for all purposes, and the Purchaser and the Seller agree that all returns and reports (including Internal Revenue Service (“IRS”) Form 8594) and all financial statements shall be prepared in a manner consistent with (and the parties shall not otherwise take a position on a Tax Return that is inconsistent with) the Allocation unless required by the IRS or any other applicable taxing authority.

1.6 Closing.

(a) The closing of the sale of the Assets to the Purchaser (the “Closing”) shall take place at the offices of ▇▇▇▇▇▇ Godward LLP in San Diego, California, at 10:00 a.m. on the Effective Date.

Subject to the limitations of authority described herein, the Seller hereby constitutes and appoints the Purchaser and its successors and assigns as its true and lawful attorney in fact in connection with the Transactions, with full power of substitution, in the name and stead of the Seller but on behalf of and for the benefit of the Purchaser and its successors and assigns, to demand and receive any and all of the Assets, and to give receipt and release for and in respect of the same and any part thereof, and from time to time to institute and prosecute, in the name of the Seller or otherwise, for the benefit of the Purchaser or its successors and assigns, proceedings at law, in equity, or otherwise, which the Purchaser or its successors or assigns reasonably deem proper in order to collect or reduce to possession or endorse any of the Assets.

In the event any such Transferred Employee accepts the Purchaser's offer of employment either before or after the Closing, the Purchaser shall be responsible for all liabilities (including but not limited to salaries and benefits, including the maintenance of appropriate levels of workers' compensation insurance) arising out of any such employment subsequent to the initial date of such employment.

4.3 Regulatory Matters and Bulk Sales Laws. The Purchaser acknowledges that it will be responsible for obtaining and maintaining the federal and state permits and licenses required in order for the Purchaser to carry on the Business or use the Assets, and except for any obligation set forth in this Agreement, that the Seller will not have duties or obligations to the Purchaser with respect to any such matters. The Purchaser agrees to waive compliance by the Seller with the provision of any “bulk sales” laws and similar applicable laws, as such laws relate to the transfer of the Assets.

4.4 ARCS Technology. The Purchaser may explore any application or enhancement to the ARCS Technology. The Seller will negotiate with the Purchaser in good faith regarding a possible license or co-marketing agreement between the parties hereto relating to the ARCS Technology.

4.5 Kan-Service Business. All of the X-Kan and Nano-Kan system assets, as set forth in Section 4.5 of the Disclosure Schedule (the “Kan Assets”), all related non-synthesis (sorting, washing and cleaving) service contracts (including without limitation the contract with Kalypsys, Inc.), and the future use of the Kan Assets to provide non-synthesis services to future customers (the “Kan Services”) shall be included in the Assets. The Purchaser shall grant the Seller a license to sell the Kan Services, as set forth in the license agreement set forth in Section 4.6 below, whether or not such Kan Services are bundled with other services provided by the Seller. The Purchaser shall permit an employee or officer of the Seller to use the Kan Assets, on an as available and “AS IS” basis (in no event to exceed, without agreement of Purchaser, 40% of the monthly usage capacity of the Kan Assets during normal business hours), at no charge to the Seller upon the reasonable request of the Seller, or, if the Seller requests and Purchaser agrees, the Purchaser shall provide the Kan Services to the Seller for an amount equal to cost plus 15%; provided, however, that Seller shall purchase consumables used in such services from Purchaser at Purchaser's then-current list price (or the price paid by a customer of the Purchaser, if more favorable), whether or not such services are conducted by Seller or Purchaser. The rights and privileges granted to the Seller under this Section 4.5 shall not be transferable or sublicenseable without the Purchaser's prior written consent, except that Seller may assign such rights and privileges to a third party that acquires all or substantially all of the Seller's assets, whether by merger or otherwise. The Seller shall be responsible for, and shall indemnify, defend, and hold the Purchaser harmless with respect to, (i) all obligations to, and claims by, the Seller's customers in connection with the Kan Services offered by the Seller to such customers, and (ii) all actions of the Seller's employees or agents in connection with their use of the Kan Assets, including without limitation any damage to such Kan Assets. The Purchaser represents and warrants that, with respect to Kan Services provided to Seller by Purchaser hereunder, Purchaser shall conduct such services in a professional and workmanlike manner comparable to the level used by Purchaser in providing such services to its other customers purchasing Kan Services. For a period of four years following the Closing Date, so long as the Purchaser continues to offer Kan Services to Persons other than the Seller, the Purchaser shall be obligated to maintain the Kan Assets in working order. The foregoing shall not be construed to prohibit the Purchaser from selling the Kan Assets and/or from discontinuing the business of providing the Kan Services during such period; provided, however, that (i) if the Purchaser sells the Kan Assets prior to the expiration of such four-year period, the Purchaser shall pay to the Seller an amount equal to 400,000, less 1/48^th of such amount for each month by which the effective date

of such sale follows the Closing Date (the “Liquidated Amount”), and (ii) if the Purchaser elects to discontinue the business of providing Kan Services during such four-year period, other than by sale of the Kan Assets as described in item (i) above, it shall notify the Seller of such election (the “Kan Notice”) at least 30 days prior to such discontinuance and, if the Seller delivers written notice to the Purchaser within 30 days of the Kan Notice, the Purchaser shall assign all of its right, title and interest in the Kan Assets (such assets to be transferred “AS-IS”) to the Seller (the “Option”). If the Seller does not exercise its Option hereunder, the Purchaser shall pay the Seller 50% of the Liquidated Amount, such amount to be determined as of the date of the delivery of the Kan Notice to the Seller (the “Notice Date”); provided, however, if the Purchaser sells the Kan Assets within 6 months of the Notice Date, the Purchaser must pay the Seller 100% of the Liquidated Amount determined as of the date of such sale less any portion previously paid by the Purchaser to the Seller.

4.6 License. The Purchaser hereby grants to the Seller an irrevocable, perpetual, worldwide, fully-paid, royalty-free, non-exclusive, under the Patent Rights solely for the purpose of providing or performing services using the inventions claimed or disclosed in such Patent Rights for the benefit of the Seller, any affiliate of the Seller and any licensee, strategic partner or customer of the Seller (the “License”). For clarity, the License does not convey any right to make, or to sell or otherwise transfer to any party, devices, equipment, software, or other products intended for use in the performance of such services. The Purchaser shall have the right, upon receipt of the Seller's prior written consent (which consent shall not be unreasonably withheld), to publicize, in a factually accurate manner, that the Seller is using systems of the Purchaser or intellectual property of the Purchaser which the Purchaser has available for sale or license, and to identify in such statements the systems and/or intellectual property the Seller is using. The License shall not be transferable or sublicenseable without the Purchaser's prior written consent, except that the Seller may assign such license to a third party that acquires all or substantially all of the Seller's assets, whether by merger or otherwise, upon the condition that the Purchaser shall have the right, upon receipt of such third party's prior written consent (which consent shall not be unreasonably withheld), to publicize such third party's use of the Purchaser's systems and/or intellectual property to the same extent as is set forth with respect to the Seller in the preceding sentence. The Purchaser makes no representations or warranties regarding the licensed Patent Rights, and expressly disclaims all warranties of merchantability, fitness for a particular purpose, or warranties of non-infringement. The Purchaser shall have no obligation to the Seller hereunder to maintain or enforce the Patent Rights. If for any reason the Purchaser intends to abandon any Patent Rights, Purchaser will use reasonable efforts to notify Seller in advance and to provide Seller the opportunity, in Seller's discretion and at Seller's expense, to take over prosecution and maintenance of any such Patent Rights on Purchaser's behalf. Notwithstanding the provisions of this Section 4.6, the Seller may not use the Patent Rights in the development, manufacture, or sale of any Prohibited Products (as defined in Section 4.9). The Seller hereby agrees to save, defend and hold the Purchaser and its agents and employees harmless from and against any and all third party suits, claims, actions and demands, and any resulting liabilities, expenses and/or losses, including reasonable legal expense and attorneys' fees, other than claims for infringement of a patent or other proprietary right of a third party (collectively, “Claims”) resulting directly or indirectly from the practice of the Patent Rights by the Seller, its affiliates, agents or sublicensees. The Seller's agreement to indemnify, defend, and hold the Purchaser and its agents and employees harmless is conditioned upon the indemnified

Person: (a) providing written notice to the Seller of any Claims arising out of the indemnified activities within thirty (30) days after the indemnified Person has knowledge of such Claims; (b) permitting the Seller to assume full responsibility and authority to investigate, prepare for, and defend against any such claim or demand; and (c) assisting the Seller, at the Seller's reasonable expense, in the investigation of, preparation for and defense of any such Claims. If the Seller assumes the defense of a Claim, the Seller will not be subject to any liability for any settlement of such claim made by the indemnified Person without the Seller's consent (but such consent will not be unreasonably withheld or delayed).

4.7 NIH Universal Store. Pursuant to the specifications attached hereto as Schedule 4.7, the Purchaser will build and install prior to December 31, 2005 (or such later date as agreed to by the Purchaser and the Seller) and the Seller shall purchase for a purchase price of $1,162,500 (the “NIH Purchase Price”) the “NIH Working Store” for the purposes of servicing the small molecule repository for the NIH (the “Repository”). The Seller shall pay to the Purchaser the NIH Purchase Price as follows: (i) $ 375,000 shall be paid following installation of the basic storage chamber associated with the NIH Working Store; (ii) $375,000 shall be paid following installation of the “cherry picking” and “I/O defrost” modules; and (iii) $412,500 shall be paid following acceptance by the Seller of the “NIH Working Store”. The Purchaser's warranty of the Repository and the terms for any future service contract between the Purchaser and the Seller that relates to the “NIH Working Store” will be in substantially the same form as the warranty and those terms included in that certain proposed warranty agreement submitted to NIH (including any implied warranties not expressly disclaimed therein) on or about the time of the purchase order of the “NIH Working Store” by NIH.

4.8 Compound Storage Business. Upon the Seller's request, the Purchaser shall provide the Seller with a written quotation and terms relating to the Purchaser's compound storage product offerings, provided that, the terms shall, for sales to Seller during the period of 3 years following the Closing Date, be at least as favorable as any terms regularly offered to the Purchaser's other customers and shall, at a minimum, reflect a discount of 25% off of the Purchaser's then-current listed rate. Furthermore, prior to purchasing compound storage product offerings from a third party, the Seller shall first allow the Purchaser to match the rate quoted by such third party, and if the Purchaser matches such third party's rate and agrees to provide the compound storage product offerings on the terms and conditions offered to the Seller by such third party the Seller shall purchase such services from the Purchaser (the “Right of First Refusal”). The Right of First Refusal shall expire on the date that is three years following the Closing Date.

4.9 Non-Competition and Non-Solicitation Agreement. For a period of two years after the Closing Date:

(a) except for any activities of officers and/or directors of the Seller not within the scope of such individual's duties to the Seller, the Seller and Seller Affiliates shall not, in any Restricted Territory, engage or be involved in the Restricted Territory in the sale of Products used in (such Products being referred to herein as the “Prohibited Products”):

(i) compound synthesizing (provided this shall not be construed to preclude the Purchaser from conducting the Kan Services in connection with synthesis by the Purchaser’s customers);

(ii) compound storage and/or management (provided that this shall not be construed to prevent or restrict the Purchaser’s sale of equipment of products to third parties for use in connection with compound storage and/or management);

(iii) protein crystallization;

(iv) drug discovery services currently provided by the Seller; or

(v) screening services currently provided by the Seller.

Notwithstanding the foregoing, the Purchaser may hire or attempt to hire ▇▇▇▇ ▇▇▇▇▇▇▇▇▇ and ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ (together, the “Permitted Hires”) to assist the Purchaser in the transition of its IT services after the Closing Date, provided that such assistance does not interfere with the Permitted Hires’ employment with the Seller.

The Purchaser shall use reasonable commercial efforts to take all actions necessary to execute and consummate such novation agreements.

4.11 Publicity. Neither the Purchaser nor the Seller shall make any disparaging statements about the other party or the other party’s products and/or services.

4.12 Business Information. Upon the Purchaser’s reasonable request, the Seller will permit the Purchaser, at its expense, to duplicate any and all written or recorded information owned and reasonably available to the Seller concerning the Business (the “Business Information”).

If the two arbitrators are unable to select a third arbitrator, a third arbitrator shall be appointed by the commercial panel of the American Arbitration Association. The arbitrator or arbitrators, as the case may be, shall set a limited time period and establish procedures designed to reduce the cost and time for discovery while allowing the parties an opportunity, adequate in the sole judgment of the arbitrator or majority of the three arbitrators, as the case may be, to discover relevant information from the opposing parties about the subject matter of the dispute. The arbitrator or a majority of the three arbitrators, as the case may be, shall rule upon motions to compel or limit discovery and shall have the authority to impose sanctions, including attorneys’ fees and costs, to the extent as a competent court of law or equity, should the arbitrators or a majority of the three arbitrators, as the case may be, determine that discovery was sought without substantial justification or that discovery was refused or objected to without substantial justification. The arbitrator(s) shall not have the power to award damages in connection with any dispute in excess of actual compensatory damages and shall not multiply actual damages or award consequential or punitive damages.

Such decision shall be written and shall be supported by written findings of fact and conclusions, which shall set forth the award, judgment, decree or order awarded by the arbitrator(s).

(b) Judgment upon any award rendered by the arbitrator(s) may be entered in any court having jurisdiction. Any such arbitration shall be held in the County of San Diego, under the rules then in effect of the American Arbitration Association. The arbitrator(s) shall determine how all expenses relating to the arbitration shall be paid, including without limitation, the respective expenses of each party, the fees of each arbitrator and the administrative fee of the American Arbitration Association.

5.15 Limitation of Liability. The maximum aggregate amount of claims, demands, damages, losses, liabilities, costs and expenses suffered or incurred by the Purchaser relating to the representations made in Sections 2.9(b),2.9(c), 2.9(e), 2.9(f), 2.9(i), 2.9(j), 2.9(k), 2.9(l), and 2.9(n) of this Agreement and for which the Seller may be liable to a Damaged Party under any theory of recovery shall not exceed $150,000.
