(a) Within forty-five (45) days following the occurrence of any one of the following events (each a "Buyout Option Event"): (i) if a Partner does not make contributions to the capital of the Partnership in addition to those contributions required by Section 8.1 upon a proposal therefor, (ii) if cumulative Net Sales (as defined below) of Products to third-party end users are less than *** over a four-year period commencing upon the first sale of the first Product or (iii) if the Partnership Business does not achieve a profit (calculated in accordance with generally accepted accounting principles) for at least one fiscal year ending prior to January 1, 2005, either Partner or an Affiliate of either Partner will have the right, but not the obligation, to initiate the buyout procedures (the initiating Partner, the "Offeror") set forth in this Section 7.8 by delivering written notice thereof (the "Offering Notice") to the other Partner (the "Offeree") which shall constitute an offer by the Offeror to purchase the Offeree's Partnership Interest in the Partnership at its fair market value. For purposes of this Section 7.8(a), "Net Sales" shall mean, with respect to any Product, the invoiced sales price of such Product billed to independent customers who are not Affiliates, less to the extent actually included in the invoiced sales price (i) credits, allowances, discounts and rebates to, and chargebacks from the account of, such independent customers for spoiled, damaged, out-dated and returned Product; (ii) actual freight and insurance costs incurred in transporting such Product in final form to such customers; (iii) cash, quantity and trade discounts, rebates and other price reduction programs; (iv) sales, value-added and other direct taxes incurred; and (v) customs duties, surcharges and other governmental charges incurred in connection with the exportation or importation of such Product in final form. (b) Within forty-five (45) days following the date of the Offering Notice, the Partners shall take all necessary steps to determine the fair market value of the Partnership and the purchase price of the Partnership Interest as set forth in subsection (h) below (the "Purchase Price"). The Partners shall set forth the Purchase Price in a written notice delivered to both Partners (the "Price Determination Notice"). (c) Within thirty (30) days following the date of the Price Determination Notice, the Offeree shall elect, at its sole option, by written notice (the "Election Notice") to the Offeror (A) to sell its Partnership Interest in the Partnership to the Offeror or (B) to buy the Partnership Interest of the Offeror at the Purchase Price. Thereafter, the party designated in the Election Notice as selling its Partnership Interest shall be referred to as the Selling Party and the party designated in the Election Notice as purchasing the Partnership Interest shall be referred to as the Purchasing Party. (d) The purchase and sale pursuant to this Section 7.8 shall be accomplished through an escrow established at a title insurance or escrow company mutually approved by the Selling Party and the Purchasing Party, and shall be consummated within forty-five (45) days following the effective date of the Price Determination Notice. The Partners shall execute such further instructions as the escrow holder and the Purchasing Party reasonably may require to consummate ***CONFIDENTIAL MATERIAL REDACTED AND FILED SEPARATELY WITH THE COMMISSION. -8- <PAGE> 38 such escrow, provided such instructions are not inconsistent with the terms of this Agreement. Closing costs shall be shared equally by the Partners. The Selling Party shall transfer to the Purchasing Party the entire Partnership Interest of the Selling Party free and clear of all liens, security interests and competing claims, and shall deliver to the Purchasing Party such instruments of transfer and such evidence of due authorization, execution and delivery and of the absence of such liens, security interests or competing claims as the Purchasing Party shall reasonably request. At the closing, the Purchasing Party shall pay the Purchase Price to the Selling Party by a wire transfer of immediately available funds to a bank account designated by the Selling Party. (e) The Purchasing Party shall, effective as of the date of the closing described in paragraph (d) above, indemnify and hold harmless the Selling Party from and against any and all claims, liabilities, causes of action, liens, charges and all other matters arising out of or in connection with the Partnership and the Partnership Business, whether arising prior to or subsequent to the date of the closing, except for unknown liabilities arising prior to the date of closing and not taken into account in calculating the Purchase Price and except for continuing obligations of the Selling Party pursuant to the Research Agreement. If the Selling Party or any Affiliate of the Selling Party is a guarantor of any obligations of the Partnership or otherwise liable thereon, prior to closing the Purchasing Party shall use reasonable best efforts to obtain a release of each such guaranty or liability in form and content reasonably acceptable to the Selling Party and its guarantor Affiliates. If such release cannot be obtained prior to closing, the Purchasing Party shall hold the Selling Party harmless with respect to such guaranties and liabilities in form and content reasonably acceptable to the Selling Party and its guarantor Affiliates. (f) Either the Purchasing Party or the Selling Party shall have the right to seek specific performance of this Section 7.8 in a court of competent jurisdiction, and the other Party shall not plead as a defense that an adequate remedy at law exists. (g) Upon the occurrence of a Buyout Option Event, if neither Partner institutes the buyout provisions set forth in Section 7.8(a), then the Partnership shall be dissolved pursuant to Section 10.1 unless the Partners otherwise agree to continue the Partnership. (h)(i) If required by subsection (b) above, each Partner will select a qualified appraiser who will determine the fair market value of the Partnership. The appraisers shall value the Partnership based on the value of the Partnership Business and, therefore, to the extent that the appraisers utilize historical financial information in their analysis, they shall take into account not only the historical net profit or loss of the Partnership for financial reporting purposes and related cash flows but also the historical Profit or Loss for financial reporting purposes (as defined in Section 2.3(c)(ii) of the Master Agreement) and related cash flows. In addition, the appraisers' analysis shall take into consideration the value of the underlying tangible and intangible assets and the liabilities of the Partnership Business. To the extent that the Selling Party or an Affiliate -9- <PAGE> 39 of the Selling Party is to perform any service or other function relating to the Partnership Business subsequent to the buyout, the amounts to be or projected to be paid for such service or function shall be taken into account by the appraisers in determining profit, loss and related cash flows projected to be generated by the Partnership Business subsequent to the buyout. For purposes of this Section 7.8(h)(i), the Partnership Business for periods subsequent to the buyout shall mean the same functions and activities encompassing the Partnership Business as defined in the Master Agreement without regard to whether the parties described in such definition are the parties performing such functions or activities after the buyout. (ii) If the fair market value of the Partnership determined by the higher of the two appraisals (the "Higher Initial Appraisal") is not greater than *** of the fair market value of the Partnership determined by the lower of the two appraisals (the "Lower Initial Appraisal"), the fair market value of the Partnership will be the average of the two appraisals; however, if the resulting value of the Partnership would not fall within this range, the two appraisers selected by the parties will select a third qualified appraiser to determine the fair market value of the Partnership. If the Higher Initial Appraisal is greater than *** but not greater than *** of the Lower Initial Appraisal, then the fair market value of the Partnership will be equal to the average of the two of the three appraisals that are closest to one another (or if the highest and lowest appraisal are equidistant from the middle, then such fair market value will be equal to the middle appraisal). If the fair market value of the Partnership determined by the Higher Initial Appraisal is greater than *** of the fair market value of the Partnership determined by the Lower Initial Appraisal, then the fair market value of the Partnership will be equal to either the Higher Initial Appraisal or the Lower Initial Appraisal, whichever is closest to the third appraisal (or if the Higher Initial Appraisal and the Lower Initial Appraisal are equidistant from the third appraisal, then such fair market value will be equal to the third appraisal). Each Partner will pay the cost of the appraiser it selects. Such parties will split the costs of a third appraiser if used. The fair market value of the Selling Partner's Partnership Interest shall be an amount equal to the balance that the Selling Partner would have in its Capital Account for purposes of Section 10.3(d) if the Partnership were liquidated at the time that the fair market value of the Partnership was the value determined under this Section 7.8(h). For purposes of determining such Capital Account balance, in applying Section 8.3(b), the value of the Partnership's assets shall be the value of the assets of the Partnership Business determined under this Section 7.8(h) in determining the fair market value of the Partnership. ***CONFIDENTIAL MATERIAL REDACTED AND FILED SEPARATELY WITH THE COMMISSION. -10- <PAGE> 40 8.

This provision is intended to be a "minimum gain chargeback" within the meaning of Sections 1.704-2(f) and 1.704-2(i)(4) of the Regulations and shall be interpreted and implemented as therein provided. (d) Qualified Income Offset. Subject to the provisions of Section 9.1(c), but otherwise notwithstanding anything to the contrary in this Section 9, if any Partner's Capital Account has a deficit balance in excess of such Partner's obligation to restore its Capital Account balance, computed in accordance with the rules of Section 1.704-l(b)(2)(ii)(d) of the Regulations (including such Partner's share of Partnership Minimum Gain and Partner Nonrecourse Debt Minimum Gain as provided in Sections 1.704-2(g) and 1.704-2(i)(5) of the Regulations), then sufficient amounts of income and gain (consisting of a pro rata portion of each item of Partnership income, including gross income, and gain for such year) shall be allocated to such Partner in an amount and manner sufficient to eliminate such deficit as quickly as possible. This provision is intended to be a "qualified income offset" within the meaning of Section 1.704-1(b)(2)(ii)(d) of the Regulations and shall be interpreted and implemented as therein provided.

Subject to the provisions of section 704(c) of the Code and Sections 9.1(b) through (d), if and to the extent the Partnership is deemed to recognize income as a result of any loans to a Partner described herein pursuant to the rules of -16- <PAGE> 46 sections 1272, 1273, 1274, 1274A, 7872, 482 or 483 of the Code, or any similar provision now or hereafter in effect, such income shall be allocated to such Partner. (g) Except as otherwise required by law, tax credits shall be allocated among the Partners in proportion to the amounts of contributions made to the Partnership by each Partner that were used by the Partnership to fund any expenditures giving rise to such tax credit, or if no expenditure gave rise to the tax credit, pro rata in accordance with the manner in which Partnership profits are allocated to the Partners under Section 9(a)(iii) as of the time the credit property is placed in service or if no property is involved, as of the time the credit is earned. Recapture of any tax credit required by the Code shall be allocated to the Partners in the same proportion in which such tax credit was allocated.

(i) Any special allocation of income or gain pursuant to Section 9.1(d) shall be taken into account in computing subsequent allocations of income and gain pursuant to this Section 9 so that the net amount of all such allocations to each Partner shall, to the extent possible, be equal to the net amount that would have been allocated to each such Partner pursuant to the provisions of this Section 9 if such special allocations of income or gain under Section 9.1(d) had not occurred. (j) (i) Items of deduction and loss attributable to recourse liabilities of the Partnership (within the meaning of section 1.752-1(a)(1) of the Regulations but excluding Partner nonrecourse debt within the meaning of Section 1.704-2(b)(4) of the Regulations) shall be allocated among the Partners in accordance with the ratio in which the Partners share the economic risk of loss (within the meaning of section 1.752-2 of the Regulations) for such liabilities.

MISCELLANEOUS 14.1 This Agreement, the Master Agreement, the Partnership Agreement, the Administrative Services Agreement and the Confidentiality Agreement together constitute the entire understanding among the parties with respect to the subject matter hereof and supersede and replace all prior agreements, understandings, writings and discussions between the parties relating to said subject matter, including, without limitation, the Prior R&D Agreement, which Prior R&D Agreement is hereby terminated immediately and of no further force and effect. In the event of any conflict between any term or provision of this Agreement and any of the foregoing agreements, the Master Agreement shall control. 14.2 This Agreement may be amended only by a written instrument executed by the parties hereto. The failure of any party at any time or times to require performance of any provision hereof shall in no manner affect its rights at a later time to enforce the same. No waiver by any party of any condition or term in any one or more instances shall be construed as a further or continuing waiver of such condition or term or any other condition or term. 14.3 The terms and provisions contained in this Agreement are for the sole benefit of the parties and their successors and assigns, and they shall not be construed as conferring and are not intended to confer any rights on any other persons. 14.4 Any delays in or failure of performance by any party under this Agreement shall not be considered a breach of this Agreement if and to the extent caused by occurrences beyond the reasonable control of the party affected, including but not limited to acts of God; acts, regulations, or laws of any government; strikes or other considered acts of workers; fires; floods; -27- <PAGE> 85 explosions; riots; wars; rebellion; and sabotage; and any time for performance hereunder shall be extended by the actual time of delay caused by such occurrence. 14.5 This Agreement shall not be assignable by either Researching Party, nor shall any of its obligations hereunder be delegated to a third party, without the prior written consent of the other Researching Party and the Partnership, which consent shall not be unreasonably withheld or delayed. In the event that the other Researching Party or the Partnership does not respond to a request from a Researching Party for consent to an assignment or delegation within fifteen (15) days following written notice requesting such consent, such Researching Party's or the Partnership's consent shall be deemed to be granted. In addition, a condition to any assignment or delegation hereunder shall be that the successor in interest expressly agrees in writing to assume the assigning or delegating party's obligations hereunder. All of the terms and provisions of this Agreement shall be binding upon and inure to the benefit of and be enforceable by the respective permitted successors and assigns. No such assignment shall release the assigning party from its obligations hereunder. Notwithstanding the foregoing, the consent of the other Researching Party and the Partnership shall not be required in connection with a merger involving either Becton or Nanogen or with respect to an assignment of this Agreement in connection with, as the case may be, the acquisition, sale of all or substantially all of the assets of Becton or Nanogen, or a change of control or similar transaction. 14.6 If any provision(s) of this Agreement are or become invalid, or are ruled illegal by any court of competent jurisdiction, or are deemed unenforceable under then current applicable law from time to time in effect during the term hereof, it is the intention of the parties hereto that the remainder of this Agreement shall not be affected thereby. It is further the -28- <PAGE> 86 intention of the parties that in lieu of each such provision which is invalid, illegal, or unenforceable, there be substituted or added as part of this Agreement, a provision which shall be as similar as possible in economic and business objectives as intended by the parties to such invalid, illegal, or unenforceable provision, but which shall be valid, legal, and enforceable, and shall be mutually agreed by the parties. 14.7 This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware without regard to its choice of laws principles. This Agreement shall be construed and interpreted without application of any principle or rule to the effect that ambiguities are to be construed against the party responsible for drafting the agreement. The headings contained herein are for reference purposes only and shall not in any way affect the meaning of this Agreement. 14.8 This Agreement may be executed in any number of counterparts, each of which shall be deemed an original, but all of which together shall constitute one instrument. 14.9 (a) During the term of this Agreement, the Partnership, Nanogen and Becton each acknowledge each party's interest in publishing certain of its results to obtain recognition within the scientific community and to advance the state of scientific knowledge. Each party also recognizes the mutual interest in obtaining valid patent protection and protecting business interests. Consequently, each party, its employees or consultants wishing to make a publication (including any oral disclosure made without obligation of confidentiality) relating to work performed by such party as part of the Research Program (the "Publishing Party") shall transmit to the Research Management Committee a copy of the proposed written publication at least forty-five (45) days prior to submission for publication, or an outline of such oral disclosure -29- <PAGE> 87 at least fifteen (15) days prior to presentation. The Research Management Committee shall have the right (i) to propose modifications to the publication for patent reasons and (ii) to request a reasonable delay in publication in order to protect patentable information. (b) If the Research Management Committee requests such a delay, the Publishing Party shall delay submission or presentation of the publication for a period of ninety (90) days to enable patent applications protecting each party's rights in such information to be filed in accordance with Paragraph 7 above. Upon the expiration of forty-five (45) days, in the case of proposed written disclosures, or fifteen (15) days, in the case of proposed oral disclosures, from transmission to the Research Management Committee, the Publishing Party shall be free to proceed with the written publication or the presentation, respectively, unless the Research Management Committee has requested the delay described above.

Service Provider and the Partnership are herein referred to jointly as the "Parties" and individually as "Party". WITNESSETH: WHEREAS, Service Provider and Nanogen, Inc. ("Nanogen") have entered into a Master Agreement dated as of October 1, 1997 (the "Master Agreement") pursuant to which Service Provider and Nanogen have formed a partnership (the "Partnership") pursuant to that certain General Partnership Agreement of even date therewith and herewith between Becton Dickinson Venture LLC, a Delaware limited liability company (the "Becton Partner"), and NanoVenture LLC, a Delaware limited liability company (the "Nanogen Partner") (the "Partnership Agreement"); and WHEREAS, the Master Agreement provides that Service Provider and the Partnership shall enter into an agreement relating to certain administrative services to be provided by Service Provider to the Partnership after the Effective Date (as such term is defined in the Master Agreement). NOW, THEREFORE, in consideration of the mutual covenants herein contained, the parties hereby agree as follows: 1. SERVICES. 1.1 Service Provider agrees to provide to the Partnership the tax, accounting and financial services (the "Services"). The Partnership shall pay for such Services an amount of compensation which shall reflect the "Reimbursable Cost" thereof, as such term is defined below. 1.2 The Parties understand that, prior to the date of this Agreement, Service Provider may have subcontracted for services in connection with all or any portion of the Services to be provided to the Partnership hereunder. Service Provider reserves the right to continue to subcontract with third parties for Services or enter into new subcontract relationships for any Service; provided, however, that any such subcontracting relationship or services shall not relieve Service Provider of any obligation to provide Services -1- <PAGE> 108 hereunder. Such subcontractors used in connection with Services provided under this Agreement will be charged to the Partnership at actual cost. 1.3 Unless otherwise agreed by the Parties, it is understood and agreed that a Party shall not provide any services not specifically provided for in this Agreement. 1.4 As used herein, the term "Reimbursable Cost" shall mean all direct and indirect costs incurred by Service Provider in performing its obligations under this Agreement as determined in accordance with generally accepted accounting principles and the accounting policies described herein and in accordance with the budget agreed to annually by the Parties hereto. 1.5.1 Such costs shall include without limitation: a. salaries and wages, b. payroll taxes, c. contract labor, d. fringe benefits, e. expenses incurred in occupying facilities (including leasehold improvements) and equipment related expenses, excluding depreciation and amortization expenses, f. recruitment and relocation, g. communications expense, h. supplies, i. freight and transportation, j. training and education, k. travel expenses, l. data processing costs, m. insurance, n. professional services, o. depreciation and amortization of facilities (including leasehold improvements) and equipment, p. a financing charge for capital acquisitions made by Service Provider for use in performing work under this Agreement, q. outside purchased services, r. sales and use taxes (including such taxes applicable to the acquisition, use, transfer or deemed transfer of property by Service Provider), s. periodic lease and rental payments under capital or financing leases, and t. periodic and special reports, 1.5.2 In determining Reimbursable Costs allocable to this Agreement, Service Provider will employ the following accounting policies: -2- <PAGE> 109 a. Capital equipment, facilities and leasehold improvements will be assigned an estimated economic useful life and salvage value, if any, and depreciation and amortization will be computed using the straight-line method. Depreciation and amortization will be allocated to Reimbursable Costs under this Agreement directly or through overhead rates applied to direct labor expense. b. Total facilities expenses of Service Provider, excluding leasehold improvement amortization allocated to specific functional areas and net of any sublease revenues, will be allocated to Reimbursable Costs under this Agreement based on the ratio of square footage utilized by or committed to use by direct and indirect personnel engaged in work under this Agreement to the total amount of utilized or committed square footage owned or leased by Service Provider. c. General and administrative expenses of Service Provider will be allocated to Reimbursable Costs under this Agreement directly or based on the ratio of total Reimbursable Costs to total operating expenses of Service Provider, excluding (in both instances) general and administrative expenses subject to such allocation. d. All other indirect expenses not covered in paragraphs (a) through (c) above which are in support of work under this Agreement will be allocated to Reimbursable Costs under this Agreement through overhead rates applied to direct labor expense. 1.5.3. The term "capital acquisition" as used herein shall mean that portion of capital equipment, leasehold improvements or other property, whenever acquired by Service Provider, which are capitalized on Service Provider's accounting records and which are either: i. purchased directly by Service Provider; ii. financed by Service Provider under a conditional sale contract; iii. financed by Service Provider through a secured loan; or iv. assets constructed in-house by Service Provider. Assets acquired under capital or financing leases will not be considered capital acquisitions for purposes of this section. With respect to capital acquisitions financed by Service Provider with specific borrowing, the financing charge referred to above will be in the amount and at the time of the actual financing costs incurred by Service Provider. With respect to capital acquisitions not financed by Service Provider with specific borrowing, the financing charge will be based on the prime lending rate in effect from time to time at Citibank, N.A., New York, New York, plus two (2) percentage points, to the extent permitted by applicable law, applied to Service Provider's net book value. Net book value is defined -3- <PAGE> 110 as the gross capital acquisition value excluding capital acquisitions financed by Service Provider with specific borrowing, less related accumulated depreciation and amortization. The financing charge for each billing period will be prorated to the extent depreciation or amortization of the capital acquisitions has been allocated to work other than work under this Agreement during such period. The financing charge will be calculated monthly based on the net book value at the end of the preceding fiscal month. 2. TERM AND RENEWAL. 2.1 The term of this Agreement shall commence as of October 1, 1997 and shall expire on September 30, 2000, unless terminated by the Parties as provided herein or conterminously with the dissolution of the Partnership or with the buyout of a Partnership Interest pursuant to Section 7.8 of the Partnership Agreement. 2.2 The Parties may, upon mutual written agreement, extend the term of this Agreement for additional, successive two (2) year terms. In the event the Partnership desires to renew this Agreement, the Partnership shall provide Service Provider with written notice ("Notice of Renewal") thirty (30) days in advance of the expiration of the Service term, or any renewal term. Service Provider shall respond in writing to the Partnership within fifteen (15) days. Upon mutual agreement of the Parties, this Agreement shall be amended in writing to effect such renewal of Services. 3. COMPENSATION. 3.1 In consideration for the Services to be performed by Service Provider, the Partnership shall pay to Service Provider the compensation described in Section 1.1 hereof. 3.2 Except as otherwise provided in the applicable schedule, invoices for Services provided hereunder shall be rendered in accordance with the Service Provider's current and reasonable practices, and invoiced amounts shall be paid promptly when due. In the event that a dispute arises, the Partnership may either pay the entire amount of the invoice (including the disputed amount) and notify the Service Provider that it disputes the invoice, or return the invoice without payment before the due date. Both parties agree that any such disputes shall be resolved in accordance with the provisions of Article V of the Master Agreement. If resolution is in favor of Service Provider, and if payment has been withheld, a late payment charge may be added to the extent permitted under applicable law, based on the Citibank, N.A., reference rate on the date such payment is made plus two (2) percentage points and computed from the date the original invoice was due to be paid to the date of payment.

In the event that the acquisition by the Partnership of the *** assets and the *** intellectual property rights is ultimately agreed upon by Becton, Nanogen and the respective parties, it is intended that Becton and Nanogen each would contribute to the Partnership *** of the *** of the purchase price payable at the closing for the *** assets, and the *** for the *** intellectual property rights. Subject to approval of the proposed transactions and agreement as to all applicable terms and conditions, Becton would lend to Nanogen not more than ***, representing Nanogen's contribution toward the aggregate *** outlay *** for the two transactions (the "Loan"), on the following basic terms: (a) The Loan would be evidenced by a Promissory Note with a term of not greater than *** (as more fully discussed below), bearing interest at the rate of *** per annum, in a form to be mutually agreed upon. (b) The entire outstanding principal balance of the Loan, together with accumulated interest thereon, would be payable on the sooner to occur of the second anniversary of the Loan or upon the consummation by Nanogen of an iniital public offering (the "IPO") of Nanoen's common stock (the "Common Stock"). In the event of Nanogen's consummation of an IPO prior to the second anniversary date, uponNanogen's consummation of the IPO: (i) the accumulated interest would be payable in full; and (ii) Becton would convert the entire outstanding principal balance of the Loan into such number of shars of the Common Stock as would result from dividing the outstanding principal balance of the Loan by the per-share price of the Common Stock in the IPO. Becton would have the right to demand that Nanogen file a registration statement covering the Common Stock to be effective no earlier than six (6) months following the closing of the IPO. In the event that such demand registration were filed prior to one (1) year following the closing of the IPO, Becton and Nanogen would split the costs of the registration, other than underwriting discounts and commissions, which would be paid by Becton. If such registration statement were filed thereafter, Nanogen would bear all costs of the registration, other than underwriting discounts and commissions, which would be paid by Becton. The registration rights would otherwise be on customary terms and conditions. 4. If the Partnership were to so determine, the Partnership would contract with Becton on terms to be negotiated to manufacture, market and sell the *** products for the Partnership. ***CONFIDENTIAL MATERIAL REDACTED AND FILED SEPARATELY WITH THE COMMISSION. <PAGE> 129 Mr. Howard C.

As part of these transactions, consistent with our mutual goal of allowig the fullest possible exploitation by the parties of the *** and *** intellectual property, the Partnership would conconcurrently confer upon each of Becton and Nanogen rights in such intellectual property as would not conflict with the Partnership's activities on arm's-length terms and conditions to be agreed upon.
