DEBTOR: NANOGEN, INC. By: Signature of Tina Berger-Nova, Ph.D. --------------------------------------- Title: President & COO ------------------------------------ Date: 5/10/94 ------------------------------------- <PAGE> 2 LEASE MANAGEMENT SERVICES, INC. EQUIPMENT FINANCING AGREEMENT (Number 10766) THIS EQUIPMENT FINANCING AGREEMENT NUMBER 10766 ("Agreement") is dated as of the date set forth at the foot hereof and is between LEASE MANAGEMENT SERVICES, INC., ("Secured Party") and NANOGEN, INC., ("Debtor"). 1. EQUIPMENT; SECURITY INTEREST. The terms and conditions of this Agreement cover each item of machinery, equipment and other property (individually an "Item" or "Item of Equipment" and collectively the "Equipment") described in a schedule now or hereafter executed by the parties hereto and made a part hereof (individually a "Schedule" and collectively the "Schedules"). Debtor hereby grants Secured Party a security interest in and to all Debtor's right, title and interest in and to the Equipment under the Uniform Commercial Code, such grant with respect to an Item of Equipment to be as of Debtor's execution of a related Equipment Financing Commitment referencing this Agreement or, if Debtor then has no interest in such Item, as of such subsequent time as Debtor acquires an interest in the Item. Such security interest is granted by Debtor to secure performance by Debtor of Debtor's obligations to Secured Party hereunder and under any other agreements under which Debtor has or may hereafter have obligations to Secured Party. Debtor will ensure that such security interest will be and remain a sole and valid first lien security interest subject only to the lien of current taxes and assessment not in default but only if such taxes are entitled to priority as a matter of law. 2. DEBTOR'S OBLIGATIONS. The obligations of Debtor under this Agreement respecting an Item of Equipment, except the obligation to pay installment payments with respect thereto which will commence as set forth in Paragraph 3 below, commence upon the grant to Secured Party of a security interest in the Item. Debtor's obligations hereunder with respect to an Item of Equipment and Secured Party's security interest therein will continue until payment of all amounts due, and performance of all terms and conditions required hereunder provided, however, that if this Agreement is in default said obligations and security interest will continue during the continuance of said default. Upon termination of Secured Party's security interest in an Item of Equipment, Secured Party will execute such release of interest with respect thereto as Debtor reasonably requests. 3. INSTALLMENT PAYMENTS AND OTHER PAYMENTS. Debtor will repay advances Secured Party makes on account of the Equipment in installment payments in the amounts and at the times set forth in the Schedules, whether or not Secured Party has rendered an invoice therefor, at the office of Secured Party set forth at the foot hereof, or to such person and/or at such other place as Secured Party may from time to time designate by notice to Debtor. Any other amounts required to be paid Secured Party by Debtor hereunder are due upon Debtor's receipt of Secured Party's invoice therefor and will be payable as directed in the invoice. Payments under this Agreement may be applied to Debtor's then accrued obligations to Secured Party in such order as Secured Party may choose. 4. NET AGREEMENT; NO OFFSET, SURVIVAL. This Agreement is a net agreement, and Debtor will not be entitled to any abatement of installment payments or other payments due hereunder or any reduction thereof under any circumstance or for any reason whatsoever. Debtor hereby waives any and all existing and future claims, as offsets, against any installment payments or other payments due hereunder and agrees to pay the installment payments and other amounts due hereunder as and when due regardless of any offset or claim which may be asserted by Debtor or on its behalf. The obligations and liabilities of Debtor hereunder will survive the termination of the Agreement. 5. FINANCING AGREEMENT. THIS AGREEMENT IS SOLELY A FINANCING AGREEMENT. DEBTOR ACKNOWLEDGES THAT THE EQUIPMENT HAS OR WILL HAVE BEEN SELECTED AND ACQUIRED SOLELY BY DEBTOR FOR DEBTOR'S PURPOSES, THAT SECURED PARTY IS NOT AND WILL NOT BE THE VENDOR OF ANY EQUIPMENT AND THAT SECURED PARTY HAS NOT MADE AND WILL NOT MAKE ANY AGREEMENT, REPRESENTATION OR WARRANTY WITH RESPECT TO THE <PAGE> 3 NANOGEN, INC. EQUIPMENT FINANCING AGREEMENT NUMBER 10766 PAGE 2 OF 8 MERCHANTABILITY, CONDITION, QUALIFICATION OR FITNESS FOR A PARTICULAR PURPOSE OR VALUE OF THE EQUIPMENT OR ANY OTHER MATTER WITH RESPECT THERETO IN ANY RESPECT WHATSOEVER. 6. NO AGENCY. DEBTOR ACKNOWLEDGES THAT NO AGENT OF THE MANUFACTURER OR OTHER SUPPLIER OF AN ITEM OF EQUIPMENT OR OF ANY FINANCIAL INTERMEDIARY IN CONNECTION WITH THIS AGREEMENT IS AN AGENT OF SECURED PARTY. SECURED PARTY IS NOT BOUND BY A REPRESENTATION OF ANY SUCH PARTY AND, AS CONTEMPLATED IN PARAGRAPH 27 BELOW, THE ENTIRE AGREEMENT OF SECURED PARTY AND DEBTOR CONCERNING THE FINANCING OF THE EQUIPMENT IS CONTAINED IN THIS AGREEMENT AS IT MAY BE AMENDED ONLY AS PROVIDED IN THAT PARAGRAPH. 7. ACCEPTANCE. Execution by Debtor and Secured Party of a Schedule covering the Equipment or any Items thereof will conclusively establish that such Equipment has been included under and will be subject to all the terms and conditions of this Agreement. If Debtor has not furnished Secured Party with an executed Schedule by the Earlier of fourteen (14) days after receipt thereof or expiration of the commitment period set forth in the applicable Equipment Financing Agreement, Secured Party may terminate its obligation to advance funds as to the applicable Equipment. 8. LOCATION; INSPECTION; USE. Debtor will keep, or in the case of motor vehicles, permanently garage and not remove from the United States, as appropriate, each Item of Equipment in Debtor's possession and control at the Equipment Location designated in the applicable Schedule, or at such other location to which such Item may have been moved with the prior written consent of Secured Party. Whenever requested by Secured Party, Debtor will advise Secured Party as to the exact location of an Item of Equipment. Secured Party will have the right to inspect the Equipment and observe its use during normal business hours, subject to Debtor's security procedures and to enter into and upon the premises where the Equipment may be located for such purpose. The Equipment will at all times be used solely for commercial or business purposes and operated in a careful and proper manner and in compliance with all applicable laws, ordinances, rules and regulations, all conditions and requirements of the policy or policies of insurance required to be carried by Debtor under the terms of this Agreement and all manufacturer's instructions and warranty requirements. Any modifications or additions to the Equipment required by any such governmental edict or insurance policy will be promptly made by Debtor. 9. ALTERATIONS; SECURITY INTEREST COVERAGE. Without the prior written consent of Secured Party, Debtor will not make any alterations, additions or improvements to any Item of Equipment which detract from its economic value or functional utility, except as may be required pursuant to Paragraph 8 above. Secured Party's security interest in the Equipment will include all modifications and additions thereto and replacements and substitutions therefor, in whole or in part. Such reference to replacements and substitutions will not grant Debtor greater rights to replace or substitute than are provided in Paragraph 11 below or as may be allowed upon the prior written consent of Secured Party. 10. MAINTENANCE: Debtor will maintain the Equipment in good repair, condition and working order. Debtor will also cause each Item of Equipment for which a service contract is generally available to be covered by such a contract which provides coverages typical to property of the type involved and is issued by a competent servicing entity. 11. LOSS AND DAMAGE; CASUALTY VALUE. In the event of the loss of, theft of, requisition of, damage to or destruction of an Item of Equipment ("Casualty Occurrence"), Debtor will give Secured Party prompt notice thereof and will thereafter place such Item in good repair, condition and working order, provided, however, that if such Item is determined by Secured Party to be lost, stolen, destroyed or damaged beyond repair, is requisitioned or suffers a constructive total loss as defined in any applicable insurance policy carried by Debtor in accordance with Paragraph 14 <PAGE> 4 NANOGEN, INC. EQUIPMENT FINANCING AGREEMENT NUMBER 10766 PAGE 3 OF 8 below, Debtor, at Secured Party's option, will (a) replace such Item with like Equipment in good repair, condition and working order whereupon such replacement equipment will be deemed such Item for all purposes hereof or (b) pay Secured Party the "Casualty Value" of such Item which will equal the total of (i) all installment payments and other amounts due from Debtor to Secured Party at the time of such payment and (ii) future installment payments due with respect to such Item with each such payment including any final uneven payment discounted at a rate equal to the discount rate of the Federal Reserve Bank of San Francisco from the date due to the date of such payment. Upon such replacement or payment, as appropriate, this Agreement and Secured Party's security interest will terminate with, and only with, respect to the Item of Equipment so replaced or as to which such payment is made in accordance with Paragraph 2 above. 12. TITLING; REGISTRATION. Each item of Equipment subject to title registration laws will at all times be titled and/or registered by Debtor as Secured Party's agent and attorney-in-fact with full power and authority to register (but without power to affect title to) the Equipment in such manner and in such jurisdiction or jurisdictions as Secured Party directs. Debtor will promptly notify Secured Party of any necessary or advisable retitling and/or reregistration of an Item of Equipment in a jurisdiction other than the one in which such Item is then titled and/or registered. Any and all documents of title will be furnished or caused to be furnished Secured Party by Debtor within sixty (60) days of the date any titling or registering or restating or reregistering, as appropriate, is directed by Secured Party. 13. TAXES. Debtor will make all filings as to and pay when due all personal property and other ad valorem taxes and all other taxes, fees, charges and assessments based on the ownership or use of the Equipment and will pay as directed by Secured Party or reimburse Secured Party for all other taxes, including, but not limited to, gross receipt taxes (exclusive of federal and state taxes based on Secured Party's net income, unless such net income taxes are in substitution for or relieve Debtor from any taxes which Debtor would otherwise be obligated to pay under the terms of this Paragraph 13), fees, charges and assessments whatsoever, however designated, whether based on the installment payments or other amounts due hereunder, levied, assessed or imposed upon the Equipment or otherwise related hereto or to the Equipment, now or hereafter levied, assessed or imposed under the authority of a federal, state, or local taxing jurisdiction, regardless of when and by whom payable. Filings with respect to such other amounts will, at Secured Party's option, be made by Secured Party or by Debtor as directed by Secured Party. 14. INSURANCE. Debtor will procure and continuously maintain all risk insurance against loss or damage to the Equipment from any cause whatsoever for not less than the full replacement value thereof naming Secured Party as Loss Payee. Such insurance must be in a form and with companies approved by Secured Party, must provide at least thirty (30) days advance written notice to Secured Party of cancellation, change or modification in any term, condition, or amount of protection provided therein, must provide full breach of warranty protection and must provide that the coverage is "primary coverage" (does not require contribution from any other applicable coverage). Debtor will provide Secured Party with an original policy or certificate evidencing such insurance. In the event of an assignment of this Agreement of which Debtor has notice, Debtor will cause such insurance to provide the same protection to the assignee as its interests may appear. The proceeds of such insurance, at the option of the Secured Party or such assignee, as appropriate, will be applied toward (a) repair or replacement of the appropriate Item or Items of Equipment, (b) payment of the Casualty Value thereof and/or (c) payment of, or as provision for, satisfaction of any other accrued obligations of Debtor hereunder. Debtor hereby appoints Secured Party as Debtor's attorney-in-fact with full power and authority to do all things, including, but not limited to, making claims, receiving payments and endorsing documents, checks or drafts, necessary to secure payments due under any policy contemplated hereby on account of a Casualty Occurrence. Debtor and Secured Party contemplate that the jurisdictions where the Equipment will be located will not impose any liability upon Secured Party for personal injury and/or property damage resulting out of the possession, use, operation or condition of the Equipment. In the event Secured Party determines that such is not or may not be the case with respect to a given jurisdiction, Debtor will provide Secured Party with <PAGE> 5 NANOGEN, INC. EQUIPMENT FINANCING AGREEMENT NUMBER 10766 PAGE 4 OF 8 public liability and property damage coverage applicable to the Equipment in such amounts and in such form as Secured Party requires. 15. SECURED PARTY'S PAYMENT. If Debtor fails to pay any amounts due hereunder or to perform any of its other obligations under this Agreement, Secured Party may, at its option, but without any obligation to do so, pay such amounts or perform such obligations, and Debtor will reimburse Secured Party the amount of such payment or cost of such performance, plus interest at 1.5% per month. 16. INDEMNITY. Debtor does hereby assume liability for and does agree to indemnify, defend, protect, save and keep harmless Secured Party from and against any and all liabilities, losses, damages, penalties, claims, actions, suits, costs, expenses and disbursements, including court costs and legal expenses, of whatever kind and nature, imposed on, incurred by or asserted against Secured Party (whether or not also indemnified against by any other person) in any way relating to or arising out of this Agreement or the manufacture, financing, ownership, delivery, possession, use, operation, condition or disposition of the Equipment by Secured Party or Debtor, including, without limitation, any claim alleging latent and other defects, whether or not discoverable by Secured Party or Debtor, and any other claim arising out of strict liability in tort, whether or not in either instance relating to an event occurring while Debtor remains obligated under this Agreement, and any claim for patent, trademark or copyright infringement. Debtor agrees to give Secured Party and Secured Party agrees to give Debtor notice of any claim or liability hereby indemnified against promptly following learning thereof. 17. DEFAULT.

REMEDIES. Upon the occurrence of an event of default, Secured Party will have the rights, options, duties and remedies of a Secured Party, and Debtor will have the rights and duties of a debtor, under the Uniform Commercial Code (regardless of whether such Code or a law similar thereto has been enacted in a jurisdiction wherein the rights or remedies are asserted) and, without limiting the foregoing, Secured Party may exercise any one or more of the following remedies: (a) declare the Casualty Value or such lesser amount as may be set by law immediately due and payable with respect to any or all Items of Equipment without notice or demand to Debtor; (b) sue from time to time for and recover all installment payments and other payments then accrued and which accrue during the pendency of such action with respect to any or all Items of Equipment; (c) take possession of and, if deemed appropriate, render unusable any or all Items of Equipment, without demand or notice, wherever same may be located, without any court order or other process of law and without liability for any damages occasioned by such taking of possession and remove, keep and store the same or use and operate or lease the same until sold; (d) require Debtor to assemble any or all Items of Equipment at the Equipment Location therefor, or at such location to which such Equipment may have been moved with the written consent of Secured Party or such other location in reasonable proximity to either of the foregoing as Secured Party designates; (e) upon ten (10) days notice to Debtor or such other notice as may be required by law, sell or otherwise dispose of any Item of Equipment, whether or not in Secured Party's possession, in a commercially reasonable manner at public or private sale at any place deemed appropriate and apply the new proceeds of such sale, after deducting all costs of such sale, including, but not limited to, costs of transportation, repossession, storage, refurbishing, advertising and brokers' fees, to the obligations of Debtor to Secured Party hereunder or otherwise, with Debtor remaining liable for any deficiency and with any excess being returned to Debtor; (f) upon thirty (30) days notice to Debtor, retain any repossessed or assembled Items of Equipment as Secured Party's own property in full satisfaction of Debtor's liability for the installment payments due hereunder with respect thereto, provided that Debtor will have the right to redeem such Items by payment in full of its obligations to Secured Party hereunder or otherwise or to require Secured Party to sell or otherwise dispose of such Items in the manner set forth in subparagraph (e) hereinabove upon notice to Secured Party within such thirty (30) day period; or (g) utilize any other remedy available to Secured Party under the Uniform Commercial Code or similar provision of law or otherwise at law or in equity. No right or remedy conferred herein is exclusive of any other right or remedy conferred herein or by law; but all such remedies are cumulative of every other right or remedy conferred hereunder or at law or in equity, by statute or otherwise, and may be exercised concurrently or separately from time to time. Any sale contemplated by subparagraph (e) of this Paragraph 18 may be adjourned from time to time by announcement at the time and place appointed for such sale, or for any such adjourned sale, without further published notice, Secured Party may bid and become the purchaser at any such sale. Any sale of an Item of Equipment, whether under said subparagraph or by virtue of judicial proceedings, will operate to divest all right, title, interest, claim and demand whatsoever; either at law or in equity, of Debtor in and to said item and will be a perpetual bar to any claim against such Item, both at law and in equity, against Debtor and all persons claiming by, through or under Debtor. 19. DISCONTINUANCE OF REMEDIES. If Secured Party proceeds to enforce any right under this Agreement and such proceedings are discontinued or abandoned for any reason or are determined adversely, then and in every such case Debtor and Secured Party will be restored to their former positions and rights hereunder. 20. SECURED PARTY'S EXPENSES. Debtor will pay Secured Party all costs and expenses, including attorney's fees and court costs and sales costs not offset against sales proceeds under Paragraph 18 above, incurred by Secured Party in exercising any of its rights or remedies hereunder or enforcing any of the terms, conditions or provisions hereof. This obligation includes the payment <PAGE> 7 NANOGEN, INC. EQUIPMENT FINANCING AGREEMENT NUMBER 10766 PAGE 6 OF 8 or reimbursement of all such amounts whether an action is ultimately filed and whether an action is ultimately dismissed. 21. ASSIGNMENT. Without the prior written consent of Secured Party, Debtor will not sell, lease, pledge or hypothecate, except as provided in this Agreement, any Item of Equipment or any interest therein or assign, transfer, pledge, or hypothecate this Agreement or any interest in this Agreement or permit the Equipment to be subject to any lien, charge or encumbrance of any nature except the security interest of Secured Party contemplated hereby. Debtors interest herein is not assignable and will not be assigned or transferred by operation of law. Consent to any of the foregoing prohibited acts applies only in the given instance and is not a consent to any subsequent like act by Debtor or any other person. All rights of Secured Party hereunder may be assigned, pledged, mortgaged, transferred or otherwise disposed of, either in whole or in part, without notice to Debtor but always, however, subject to the rights of Debtor under this Agreement. If Debtor is given notice of any such assignment, Debtor will acknowledge receipt thereof in writing. In the event Secured Party assigns this Agreement or the installment payments due or to become due hereunder or any other interest herein, whether as security for any of its indebtedness or otherwise, no breach or default by Secured Party hereunder or pursuant to any other agreement between Secured Party and Debtor, should there be one, will excuse performance by Debtor of any provision hereof, it being understood that in the event of such default or breach by Secured Party that Debtor will pursue any rights on account thereof solely against Secured Party. No such assignee, unless such assignee agrees in writing, will be obligated to perform any duty, covenant or condition required to be performed by Secured Party in connection with this Agreement. Subject always to the foregoing, this Agreement inures to the benefit of, and is binding upon, the heirs, legatees, personal representative, successors and assigns of the parties hereto. 22. MARKINGS; PERSONAL PROPERTY. If Secured Party supplies Debtor with labels, plates, decals or other markings stating that Secured Party has an interest in the Equipment, Debtor will affix and keep the same prominently displayed on the Equipment or will otherwise mark the Equipment or its then location or locations, as appropriate, at Secured Party's request to indicate Secured Party's security interest in the Equipment. The Equipment is, and at all times will remain, personal property notwithstanding that the Equipment or any Item thereof may now be, or hereafter become, in any manner affixed or attached to, or embedded in, or permanently resting upon real property or any improvement thereof or attached in any manner to what is permanent as by means of cement, plaster, nails, bolts, screws or otherwise. If requested by Secured Party, Debtor will obtain and deliver to Secured Party waivers of interest or liens in recordable form satisfactory to Secured Party from all persons claiming any interest in the real property on which an Item of Equipment is or is to be installed or located. 23. LATE CHARGES. Time is of the essence in this Agreement and if any Installment Payment is not paid within ten (10) days after the due date thereof, Secured Party shall have the right to add and collect, and Debtor agrees to pay: (a) a late charge on and in addition to, such Installment Payment equal to five percent (5%) of such Installment Payment or a lesser amount if established by any state or federal statute applicable thereto, and (b) interest on such Installment Payment from thirty (30) days after the due date until paid at the highest contract rate enforceable against Debtor under applicable law but never to exceed eighteen percent (18%) per annum. 24. NON-WAIVER. No covenant or condition of this Agreement can be waived except by the written consent of Secured Party. Forbearance or indulgence by Secured Party in regard to any breach hereunder will not constitute a waiver of the related covenant or condition to be performed by Debtor. 25. ADDITIONAL DOCUMENTS.

EQUIPMENT FINANCING AGREEMENT NUMBER 10766 PAGE 7 OF 8 Secured Party such financing statements and similar documents as Secured Party requests.

Debtor will pay as directed by Secured Party or reimburse Secured Party for all filing, search, title report, legal and other fees incurred by Secured Party in connection with any documents to be provided by Debtor pursuant to this Paragraph or Paragraph 22 and any further similar documents Secured Party may procure. 26. DEBTOR'S WARRANTIES. Debtor certifies and warrants that the financial data and other information which Debtor has submitted, or will submit, to Secured Party in connection with this Agreement is, or will be at time of delivery, as appropriate, a true and complete statement of the matters therein contained. Debtor further certifies and warrants: (a) this Agreement has been duly authorized by Debtor and when executed and delivered by the person signing on behalf of Debtor below will constitute the legal, valid and binding obligation, contract and agreement of Debtor enforceable against Debtor in accordance with its respective terms; (b) this Agreement and each and every showing provided by or on behalf of Debtor in connection herewith may be relied upon by Secured Party in accordance with the terms thereof notwithstanding the failure of Debtor or other applicable party to ensure proper attestation thereto, whether by absence of a seal or acknowledgment or otherwise; (c) Debtor has the right, power and authority to grant a security interest in the Equipment to Secured Party for the uses and purposes herein set forth and (d) each Item of Equipment will, at the time such Item becomes subject hereto, be in good repair, condition and working order. 27.

Whenever the context of this Agreement requires, the neuter gender includes the feminine or masculine and the singular number includes the plural; and whenever the words "Secured Party" are used herein, they include all assignees of Secured Party, it being understood that specific reference to "assignee" in Paragraph 14 above is for further emphasis. If there is more than one Debtor named in this Agreement, the liability of each will be joint and several. 30. TITLES. The titles to the Paragraphs of this Agreement are solely for the convenience of the parties and are not an aid in the interpretation of the instrument. 31. GOVERNING LAW; VENUE.

All such insurance policies shall protect Lessor and Lessee, as their respective interests may appear, and shall provide that all losses shall be payable to and adjusted solely with Lessor. Lessee shall, at Lessee's own expense, also maintain public liability insurance, in such form and with such companies as are satisfactory to Lessor, insuring Lessor with respect to injury to person or property resulting from the condition, locations, maintenance, and actual or alleged use of the Equipment. Lessee shall, prior to the acceptance of a Schedule by Lessor, deliver to Lessor each of the foregoing policies or satisfactory evidence of such insurance. Each such policy shall contain an endorsement providing that the insurer will give Lessor not less than 30 days' prior written notice of the effective date of any alteration or cancellation of such policy. Lessee shall furnish annually to Lessor satisfactory evidence of the maintenance of such insurance. Lessee hereby irrevocably appoints Lessor as Lessee's attorney-in-fact to make claim for, receive payment of, and execute any and endorse all documents for loss or damages under any insurance policy as herein specified. In case of the failure of Lessee to maintain any of such insurance, Lessor shall have the right, but shall not be obligated, to obtain such insurance, and therefor, Lessee hereby grants Lessor the irrevocable right to select an insurance broker for the procurement and maintenance of such insurance coverage herein specified. 10.

NANOGEN hereby agrees to repay immediately, and without demand, all sums so expended by LMSI, with interest from date of expenditure at the rate of Eighteen Percent (18%), but never to exceed any legal limit for such interest. Any officer of LMSI is hereby irrevocably appointed the attorney-in-fact of NANOGEN, with full power of substitution, to sign any certificate of ownership, registration card, application therefor, affidavits or documents necessary to transfer title to any of the Collateral, to receive and give receipt for all licenses, registration cards and certificates of ownership, and to do all acts necessary or incident to the powers granted to LMSI herein, as full as NANOGEN might. Should NANOGEN default under the Lease, upon written notice, pursuant to the terms and conditions of the Agreements, LMSI may (a) immediately take possession of the Collateral wherever it may be found, using all necessary force to do so or require NANOGEN to assemble the Collateral and make it available to LMSI at a place designated by LMSI which is reasonably convenient to LMSI, and NANOGEN waives all claims for damages due to or arising from or connected with any such taking; (b) proceed in the foreclosure of LMSI's security interest and the sale of the Collateral in any manner permitted by law, or provided for herein; (c) sell, lease or otherwise dispose of the Collateral at public or private sale, with or without having the Collateral at the place of sale, and upon terms and in such manner as LMSI may determine, and LMSI may purchase the same at any such sale; (d) retain the Collateral in full satisfaction of the obligations secured thereby; (e) exercise any remedies of a LMSI under the Uniform Commercial Code. Prior to any such disposition, LMSI may, at its option, cause any of the Collateral to be repaired or reconditioned in such manner and to such extent as LMSI may deem advisable, and any sums expended therefor by LMSI shall be repaid by NANOGEN and secured hereby; LMSI shall have the right to enforce one or more remedies hereunder successively or concurrently, and any such action shall not stop or prevent LMSI from pursuing any further remedy which it may have hereunder or by law. If a sufficient sum is not realized from any such disposition of Collateral to pay all obligations secured by this agreement, NANOGEN hereby promises and agrees to pay LMSI any deficiency. Time and exactitude of each of the terms, obligations, covenants and conditions are hereby declared to be the essence hereof. No waiver by LMSI of any breach or default shall be deemed a waiver of any breach or default thereafter occurring and the taking of any action by LMSI shall not be deemed to be an election of that action but rather the rights and privileges and options <PAGE> 18 COLLATERAL SECURITY AGREEMENT NANOGEN, INC. PAGE 3 OF 3 granted to LMSI under the terms hereof shall be deemed cumulative, the one with the other and not alternative. Should the Collateral be sold, with or without the consent of LMSI, then it is expressly agreed that the proceeds from said sale are hereby assigned to LMSI who shall immediately receive the entire proceeds. NANOGEN agrees to execute any additional documents deemed necessary by LMSI to assure the perfection of the security interest created hereunder and to pay any fees or charges paid by LMSI in connection with the perfection of, or continue the perfection of, the security interest created hereunder. Upon termination of the Agreements and the satisfaction of all obligations of NANOGEN thereunder, LMSI shall release its security interest in the Collateral, and this Collateral Security Agreement shall thereupon be without further effect.
