 THIS LOAN AND SECURITY
AGREEMENT (“Loan Agreement” or “Agreement”) is entered into on the above date among PARTNERS FOR GROWTH, L.P. (“PFG”), whose address is 180 Pacific Avenue, San Francisco, CA 94111 Xenogen Corporation (the
“Parent”), whose chief executive office is located at the above address (“Parent’s Address”) and Xenogen Biosciences Corporation (“XBC”), whose chief executive office is located at the above address
(“XBC’s Address”). Each of Parent and XBC is a “Borrower” and collectively, they are the “Borrowers”. The Schedule to this Agreement (the “Schedule”) being signed by the parties concurrently, is an
integral part of this Agreement. (Definitions of certain terms used in this Agreement are set forth in Section 8 below.) 
  
  
 1. LOANS. 
  
 1.1 Loans. Subject to Section 1.8, PFG will make loans to Borrowers (the “Loans”), in accordance
with the provisions of Section 1.7, up to the amounts (the “Credit Limit”) shown on the Schedule, provided no Default or Event of Default has occurred and is continuing and, at any time there are monetary Obligations outstanding or
requested by a Borrower, subject to reduction of the Credit Limit to reflect such Reserves as PFG deems appropriate from time to time in its good faith business judgment. 
  
 1.2 Interest. All Loans and all other monetary Obligations shall bear interest at the rate shown on the
Schedule, except where expressly set forth to the contrary in this Agreement. Interest shall be payable monthly, on the last day of the month. Interest that is not paid when due may, in PFG’s discretion, be charged to Parent’s loan
account, and the same shall thereafter bear interest at the same rate as the other Loans. 
  
 1.3 Overadvances. If, at any time or for any reason, the total of all outstanding Loans and all other monetary Obligations then due exceeds the Credit Limit (an “Overadvance”), subject to the
rights of the Senior Lender, Borrowers shall immediately pay the amount of the excess to PFG, without notice or demand. Without limiting Borrower’s obligation to repay to PFG the amount of any Overadvance, Borrowers agree to pay PFG interest on
the outstanding amount of any Overadvance, on demand, at the Default Rate. 
  
 1.4 Fees. Borrowers shall pay PFG the fees shown on the Schedule, which are in addition to all interest and other sums payable to PFG and are not refundable. 
  
 1.5 Loan Requests. To obtain a Loan, Agent shall make a request
to PFG by facsimile or telephone. Loan requests may also be made by a Borrower by email, but the same shall not be deemed made until PFG acknowledges receipt of the same by email or otherwise in writing. PFG will use reasonable commercial efforts to
fund any requests for Loans within ten (10) Business Days of its receipt of all information it may request of Borrowers in connection with such Loan request, including without limitation, all information which is not required to be delivered under
the terms of this Agreement to PFG if there are no monetary Obligations outstanding to PFG. PFG may rely on any telephone request for a Loan given by a person whom PFG believes in good faith is a Responsible Officer of Agent, and each Borrower will
indemnify PFG for any loss PFG suffers as a result of that reliance. 
  
 1.6 Late Fee. If any payment of accrued interest for any month is not made within three business days after the date a bill therefor is sent by PFG to Borrower, or if any payment of principal or any other payment is not made
within three Business Days after the date due, Borrower shall pay PFG a late payment fee equal to 5% of the amount of such late payment. The provisions of this paragraph shall not be construed as PFG’s consent to Borrower’s failure to pay
any amounts when due, and PFG’s acceptance of any such late payments shall not restrict PFG’s exercise of any remedies arising out of any such failure.

 1.7 Agented Loan
Arrangement. 
  
 (a) XBC hereby designates
Parent as its agent (the “Agent”) to discharge the duties and responsibilities of the Agent as provided in this Section 1.7. Except as otherwise permitted by PFG, loans hereunder shall be requested solely by the Agent as agent for each
Borrower. Any Loan which may be made by PFG under this Agreement and which is directed to the Agent is received by the Agent in trust for that Borrower who is intended to receive such Loan. The Agent shall distribute the proceeds of any such Loan
solely to that Borrower. Each Borrower shall be directly indebted to PFG for each Loan distributed to any Borrower by the Agent, together with all accrued interest thereon, as if that amount had been advanced directly by PFG to a Borrower (whether
or not the subject Loan was based upon the assets of the Borrower which actually received such distribution), in addition to which each Borrower shall be liable to PFG for all Obligations under this Agreement, whether or not the proceeds of the Loan
are distributed to any particular Borrower. PFG shall have no responsibility to inquire as to the distribution of Loans made by PFG through the Agent as described herein. 
  
 (b) If Agent withdraws as Agent hereunder, or is otherwise unable to, or prohibited from carrying out its obligations as
Agent under this Agreement (as determined by PFG in its reasonable discretion in consultation with Borrower); PFG’s obligation to make Loans hereunder shall terminate. 
  
 (c) The authority of the Agent to request Loans on behalf of, and to bind, each Borrower, shall continue unless and until
PFG acts as provided in Section 1.7(b) above, or PFG actually receives: (i) written notice of: (A) the termination of such authority, and (B) the subsequent appointment of a successor Agent, which notice is executed by the respective chief executive
or financial officers of each Borrower (other than the chief executive officer of the Agent being replaced) then eligible for borrowing under this Agreement; and (ii) written notice from the successor Agent (A) accepting such appointment; (B)
acknowledging that the removal and appointment has been effected by the respective chief executive or financial officer of each Borrower eligible for borrowing under the within Agreement; and (B) acknowledging that from and after the date of
appointment, the newly appointed Agent shall be bound by the terms hereof, and that as used herein, the term “Agent” shall mean and include the newly appointed Agent. 
  
 (d) The Agent and each Borrower respectively shall indemnify, defend, and save and hold PFG harmless from and against any
liabilities, claims, demands, expenses, or losses made against or suffered by PFG on account of, or arising out of, this Agreement, PFG’s reliance upon Loan requests made by the Agent, or any other action taken by PFG hereunder or under any of
PFG’s various agreements with the Agent and/or any Borrower and/or any other Person arising under this Agreement, absent PFG’s gross negligence or intentional misconduct. 
  
 1.8 Conditional Obligation to Lend. Notwithstanding anything to the contrary set forth in this Agreement and
in addition to PFG’s right to impose Reserves at any time, the obligation of PFG to make each and every Loan shall be subject to and conditional upon PFG’s determination in its sole judgment at the time of any Borrower request for a Loan
that from the date hereof until the date of such request, no transactions that would not otherwise have been permitted under Section 5.5 have occurred (irrespective of whether or not monetary Obligations are or were, at the time of any such
transactions, outstanding). If any such transactions have occurred, it may, inter alia, condition any Loan on such additional or modified terms and conditions as it may determine appropriate in its sole discretion.  
  
 2. SECURITY INTEREST. 
  
 2.1 Grant of Security Interest. To secure the payment and
performance of all of the Obligations when due, each Borrower hereby grants to PFG a security interest in all of the following (collectively, the “Collateral”): all right, title and interest of such Borrower in and to all of the following,
whether now owned or hereafter arising or acquired and wherever located: all Accounts; all Inventory; all Equipment; all Deposit Accounts; all General Intangibles (excluding Intellectual Property); all Investment Property; all Other Property; and
any and all claims, rights and interests in any of the above, and all guaranties and security for any of the above, and all substitutions and replacements for, additions, accessions, attachments, accessories, and improvements to, and proceeds
(including proceeds of any insurance policies, proceeds of proceeds and claims against third parties) of, any and all of the above, and all of such Borrower’s books relating to any and all of the above. Notwithstanding anything contained in
this Section 2, the term Collateral shall not include any property that is subject to a lien that is otherwise permitted pursuant to subsection (ii) of the definition of “Permitted Liens.” 
  
 2.2 Excluded Collateral. Notwithstanding the foregoing, the
Collateral shall not be deemed to include any copyrights, copyright applications, copyright registration and like protection in each work of authorship and derivative work thereof, whether published or unpublished, now owned or hereafter acquired;
any patents, patent applications and like protections including without limitation improvements, divisions, continuations, renewals, reissues, extensions and continuations-in-part of the same, trademarks, servicemarks and applications therefor,
whether registered or not, and the goodwill of the business of either Borrower connected with and symbolized by such trademarks, any trade secret rights, including any rights to unpatented inventions, know-how, operating manuals, license rights and
agreements and confidential information, now owned or hereafter acquired; or any claims for damage by way of any past, present and future infringement of any of the foregoing (collectively, the “Intellectual Property”), except that the
Collateral shall include the proceeds of all the Intellectual

	Partners for Growth	 	Loan and Security Agreement

  
 Property that are accounts, (i.e.
accounts receivable) of either Borrower, or general intangibles consisting of rights to payment, if a judicial authority (including a U.S. Bankruptcy Court) holds that a security interest in the underlying Intellectual Property is necessary to have
a security interest in such accounts and general intangibles of Borrower that are proceeds of the Intellectual Property, then the Collateral shall automatically, and effective as of the Closing Date, include the Intellectual Property to the extent
necessary to permit perfection of Silicon’s security interest in such accounts and general intangibles of Borrowers that are proceeds of the Intellectual Property. Notwithstanding anything contained in this paragraph, the term Collateral shall
not include any property that is subject to a Lien is otherwise permitted pursuant to paragraph (c) of the definition of “Permitted Liens.” 
  
 3. REPRESENTATIONS, WARRANTIES AND COVENANTS OF BORROWER.

date each Loan is made or requested to be made hereunder and on the date each Compliance Certificate is delivered to PFG as follows, and each Borrower covenants that at any time there are Loans or other monetary Obligations outstanding to or
requested from PFG, it will comply with all of the following covenants until all Obligations have been paid and performed in full: 
  
 3.1 Corporate Existence and Authority. Such Borrower is and will continue to be, duly organized, validly existing and in good standing under
the laws of the jurisdiction of its incorporation. Such Borrower is and will continue to be qualified and licensed to do business in all jurisdictions in which any failure to do so would result in a Material Adverse Change. The execution, delivery
and performance by such Borrower of this Agreement, and all other documents contemplated hereby (i) have been duly and validly authorized, (ii) are enforceable against such Borrower in accordance with their terms (except as enforcement may be
limited by equitable principles and by bankruptcy, insolvency, reorganization, moratorium or similar laws relating to creditors’ rights generally), and (iii) do not violate such Borrower’s articles or certificate of incorporation, or such
Borrower’s by-laws, or any law or any material agreement or instrument which is binding upon such Borrower or its property, and (iv) do not constitute grounds for acceleration of any material indebtedness or obligation under any agreement or
instrument which is binding upon such Borrower or its property. 
  
 3.2 Name; Trade Names and Styles. As of the date hereof, the name of such Borrower set forth in the heading to this Agreement is its correct name, as set forth in its Articles or Certificate of Incorporation. Listed in the
Representations are all prior names of such Borrower and all of such Borrower’s present and prior trade names as of the date hereof. Such Borrower shall give PFG 30 days’ prior written notice before changing its name or doing business
under any other name. Such Borrower has complied, and will in the future comply, in all material respects, with all laws relating to the conduct of business under a fictitious business name, if applicable to such Borrower except where the failure to
do so could not reasonably be expected to result in a Material Adverse Change. 
  
 3.3 Place of Business; Location of Collateral. As of the date hereof, the address set forth in the heading to this Agreement is such Borrower’s chief executive office. In addition, as of the date
hereof, such Borrower has places of business and Collateral is located only at the locations set forth in the Representations. such Borrower will give PFG at least 30 days prior written notice before opening any additional place of business,
changing its chief executive office, or moving any of the Collateral to a location other than such Borrower’s Address or one of the locations set forth in the Representations, except that such Borrower may maintain sales offices in the ordinary
course of business at which not more than a total of $100,000 fair market value of Equipment is located. 
  
 3.4 Title to Collateral; Perfection; Permitted Liens. 
  
 (a) Such Borrower is now, and will at all times in the future be, the sole owner of all the Collateral, except for items of
Equipment which are leased to such Borrower. The Collateral now is and will remain free and clear of any and all liens, charges, security interests, encumbrances and adverse claims, except for Permitted Liens. PFG now has, and will continue to have,
a priority (subject only to the security interest of the Senior Lender, to the extent of the Senior Debt Limit) perfected and enforceable security interest in all of the Collateral, subject only to the Permitted Liens, and such Borrower will at all
times defend PFG and the Collateral against all claims of others. 
  
 (b) Such Borrower has set forth in the Representations all of such Borrower’s Deposit Accounts, and such Borrower will give PFG five Business Days advance written notice before establishing any new Deposit Accounts and will, subject to
the rights of the Senior Lender, cause the institution where any such new Deposit Account is maintained to execute and deliver to PFG a control agreement in form sufficient to perfect PFG’s security interest in the Deposit Account and otherwise
satisfactory to PFG in its good faith business judgment. 
  
 (c)
In the event that such Borrower shall at any time after the date hereof have any commercial tort claims against others, which it is asserting, and in which the potential recovery exceeds $100,000, such Borrower shall promptly notify PFG thereof in
writing and provide PFG with such information regarding the same as PFG shall request (unless providing such 
  

 -3- 








			
	Partners for Growth	 	Loan and Security Agreement

  
 information would waive the such
Borrower’s attorney-client privilege). Such notification to PFG shall constitute a grant of a security interest in the commercial tort claim and all proceeds thereof to PFG, and such Borrower shall execute and deliver all such documents and
take all such actions as PFG shall request in connection therewith. 
  
 (d) None of the Collateral now is or will be affixed to any real property in such a manner, or with such intent, as to become a fixture. Except as set forth in the Representations, such Borrower is not and will not become a lessee under any
real property lease pursuant to which the lessor may obtain any rights in any of the Collateral and no such lease now prohibits, restrains, impairs or will prohibit, restrain or impair such Borrower’s right to remove any Collateral from the
leased premises. Whenever any Collateral is located upon premises in which any third party has an interest, such Borrower shall, whenever requested by PFG at any time there are monetary Obligations outstanding or requested by a Borrower, use
commercially reasonable efforts to cause such third party to execute and deliver to PFG, in form acceptable to PFG, such waivers and subordinations as PFG shall specify in its good faith business judgment. Such Borrower will keep in full force and
effect, and will comply with all material terms of, any lease of real property where any of the Collateral now or in the future may be located. 
  
 3.5 Maintenance of Collateral. Such Borrower will maintain the Collateral in good working condition (ordinary wear and tear excepted), and
such Borrower will not use the Collateral for any unlawful purpose. Such Borrower will immediately advise PFG in writing of any material loss or damage to the Collateral. 
  
 3.6 Books and Records. Such Borrower has maintained and will maintain at such Borrower’s Address (or in
the case of XBC, also at Parent’s address) complete and accurate books and records, comprising an accounting system in accordance with GAAP. 
  
 3.7 Financial Condition, Statements and Reports. All financial statements now or in the future delivered to PFG have been, and will be,
prepared in conformity with GAAP and now and in the future will fairly present the consolidated results of operations and consolidated financial condition of Parent in all material respects, in accordance with GAAP (except that interim financial
statements shall be subject to year-end adjustment and shall not have footnotes), at the times and for the periods therein stated. Between the last date covered by any such statement provided to PFG and the date hereof, there has been no Material
Adverse Change. 
  
 3.8 Tax Returns and Payments; Pension
Contributions. Such Borrower has timely filed, and will timely file, all required tax returns and reports, and such Borrower has timely paid, and will timely pay, all foreign, federal, state and local taxes, assessments, deposits and
contributions now or in the future owed by such Borrower. Such Borrower may, however, defer payment of any of the foregoing which are contested by such Borrower in good faith, provided that such Borrower (i) contests the same by appropriate
proceedings promptly and diligently instituted and conducted, (ii) notifies PFG in writing of the commencement of, and any material development in, the proceedings, and (iii) posts bonds or takes any other steps required to keep the same from
becoming a lien upon any of the Collateral. Such Borrower is unaware of any claims or adjustments proposed for any of such Borrower’s prior tax years which could result in additional taxes becoming due and payable by such Borrower. Such
Borrower has paid, and shall continue to pay all amounts necessary to fund all present and future pension, profit sharing and deferred compensation plans in accordance with their terms, and such Borrower has not and will not withdraw from
participation in, permit partial or complete termination of, or permit the occurrence of any other event with respect to, any such plan which could reasonably be expected to result in any liability of such Borrower, including any liability to the
Pension Benefit Guaranty Corporation or its successors or any other governmental agency. 
  
 3.9 Compliance with Law. Such Borrower has, to the best of its knowledge, complied, and will comply, in all material respects, with all provisions of all foreign, federal, state and local laws and
regulations applicable to such Borrower, including, but not limited to, those relating to such Borrower’s ownership of real or personal property, the conduct and licensing of such Borrower’s business, and all environmental matters except
where the failure to do so could not reasonably be expected to result in a Material Adverse Change. 
  
 3.10 Litigation. Except as set forth in the Representations, there is no claim, suit, litigation, proceeding or investigation pending or (to
best of such Borrower’s knowledge) threatened against or affecting such Borrower in any court or before any governmental agency (or any basis therefor known to such Borrower) which could reasonably be expected to result, either separately or in
the aggregate, in any Material Adverse Change. Each Borrower will promptly inform PFG in writing of any claim, proceeding, litigation or investigation in the future threatened or instituted against such Borrower involving any single claim of $50,000
or more, or involving $100,000 or more in the aggregate. 
  
 3.11 Use of Proceeds. All proceeds of all Loans shall be used solely for lawful business purposes. Such Borrower is not purchasing or carrying any “margin stock” (as defined in Regulation U of the Board of Governors
of the Federal Reserve System) and no part of the proceeds of any Loan will be used to purchase or carry any “margin stock” or to extend credit to others for the purpose of purchasing or carrying any “margin stock.”

 4.1 Representations Relating to Accounts. Each Borrower represents and warrants as of the date of this
Agreement and as of the date of each Loan made hereunder to PFG as follows: Each Account reflected on such Borrower’s books shall, on the date each Loan is requested and made, represent an undisputed bona fide existing unconditional obligation

and all unpaid balances appearing in all invoices, instruments and other documents evidencing the Accounts are and shall be true and correct in all material respects and all such invoices, instruments and other documents and all of such
Borrower’s books and records are and shall be genuine and in all respects what they purport to be. All sales and other transactions underlying or giving rise to each Account shall comply in all material respects with all applicable laws and
governmental rules and regulations. To the best of each Borrower’s knowledge, all signatures and endorsements on all documents, instruments, and agreements relating to all Accounts are and shall be genuine, and all such documents, instruments
and agreements are and shall be legally enforceable in accordance with their terms. 
  
 4.3 Documents Relating to Accounts. If requested by PFG, at any time there are monetary Obligations outstanding to or requested by any Borrower; each such Borrower shall furnish PFG with copies (or, at
PFG’s request, originals) of all contracts, orders, invoices, and other similar documents, and all shipping instructions, delivery receipts, bills of lading, and other evidence of delivery, for any goods the sale or disposition of which gave
rise to such Accounts, and such Borrower warrants the genuineness of all of the foregoing. Each Borrower shall also furnish to PFG an aged accounts receivable trial balance as provided in the Schedule. In addition, subject to the rights of the
Senior Lender, each Borrower shall deliver to PFG, on its request, the originals of all instruments, chattel paper, security agreements, guarantees and other documents and property evidencing or securing any Accounts, in the same form as received,
with all necessary indorsements, and copies of all credit memos. 
  
 4.4 Collection of Accounts. Borrowers shall have the right to collect all Accounts, unless and until a Default or an Event of Default has occurred and is continuing. Subject to the rights of the Senior Lender, PFG may, in its
good faith business judgment, require that all proceeds of Collateral be deposited by each Borrower into a lockbox account, or such other “blocked account” as PFG may specify, pursuant to a blocked account agreement in such form as PFG may
specify in its good faith business judgment. 
  
 4.5.
Remittance of Proceeds. At any time there are monetary Obligations outstanding or requested by a Borrower, subject to the rights of the Senior Lender, all proceeds arising from (i) the disposition of any Collateral, and (ii)

course of business, or (y) the proceeds of the sale of worn out or obsolete Equipment disposed of by Borrower in good faith in an arm’s length transaction for an aggregate purchase price of $25,000 or less (for all such transactions in any
fiscal year). Borrower agrees that it will not commingle proceeds of Collateral with any of Borrower’s other funds or property, but will hold such proceeds separate and apart from such other funds and property and in an express trust for PFG,
except as set forth above, and subject to the rights of the Senior Lender. Nothing in this Section limits the restrictions on disposition of Collateral set forth elsewhere in this Agreement. 
  
 4.6 Disputes. At any time there are monetary Obligations
outstanding or requested by a Borrower, Borrower shall notify PFG promptly of all disputes or claims relating to Accounts. Borrower shall not forgive (completely or partially), compromise or settle any Account for less than payment in full, or agree

 -5- 








			
	Partners for Growth	 	Loan and Security Agreement

  
 Inventory to Borrower, Borrower shall
promptly determine the reason for such return and promptly issue a credit memorandum to the Account Debtor in the appropriate amount. In the event any attempted return occurs after the occurrence and during the continuance of any Event of Default,
Borrower, upon PFG’s request, shall hold the returned Inventory in trust for PFG, and immediately notify PFG of the return of the Inventory. 
  
 4.8 Verification. At any time there are monetary Obligations outstanding or requested by a Borrower (and subject to the rights of the Senior
Lender),PFG may, from time to time, verify directly with the respective Account Debtors the validity, amount and other matters relating to the Accounts, by means of mail, telephone or otherwise, either in the name of Borrower or PFG or such other
name as PFG may choose. 
  
 4.9 No Liability. PFG
shall not be responsible or liable for any shortage or discrepancy in, damage to, or loss or destruction of, any goods, the sale or other disposition of which gives rise to an Account, or for any error, act, omission, or delay of any kind occurring
in the settlement, failure to settle, collection or failure to collect any Account, or for settling any Account in good faith for less than the full amount thereof, nor shall PFG be deemed to be responsible for any of a Borrower’s obligations
under any contract or agreement giving rise to an Account. Nothing herein shall, however, relieve PFG from liability for its own gross negligence or willful misconduct. 
  
 5. ADDITIONAL DUTIES OF BORROWERS. 
  

5.1 Financial and Other Covenants. Each Borrower shall at all times comply with the covenants set forth in the Schedule.

except that, provided no Default or Event of Default has occurred and is continuing, PFG shall release to such Borrower insurance proceeds with respect to Equipment totaling less than $100,000, which shall be utilized by such Borrower for the
replacement of the Equipment with respect to which the insurance proceeds were paid. PFG may require reasonable assurance that the insurance proceeds so released will be so used. If such Borrower fails to provide or pay for any insurance, PFG may,
but is not obligated to, obtain the same at such Borrower’s expense. Such Borrower shall promptly deliver to PFG copies of all material reports made to insurance companies. 
  
 5.3 Reports. At any time there are monetary Obligations outstanding or requested by a Borrower, Parent, at its
expense, shall provide PFG with the written reports set forth in the Schedule, and such other written reports with respect to either Borrower (including budgets, projections, operating plans and other financial documentation), as PFG shall from time
to time specify in its good faith business judgment. 
  
 5.4
Access to Collateral, Books and Records. At any time there are monetary Obligations outstanding or requested by a Borrower, at reasonable times, and on one Business Day’s notice, PFG, or its agents, shall have the right to inspect the
Collateral, and the right to audit and copy Borrowers’ books and records. The foregoing inspections and audits shall be at Borrower’s expense and the charge therefor shall be $750 per person per day (or such higher amount as shall
represent PFG’s then current standard charge for the same), plus reasonable out-of-pocket expenses. Neither Borrower shall be required to disclose to PFG any document or information (i) where disclosure is prohibited by applicable law, rule or
regulation or any agreement binding on such Borrower, or (ii) is subject to attorney-client or similar privilege or constitutes attorney work product. If such Borrower is withholding any information under the preceding sentence, it shall so advise
PFG in writing, giving PFG a general description of the nature of the information withheld. 
  
 5.5 Negative Covenants. Except as may be permitted in the Schedule and except when there are no monetary Obligations outstanding or requested by a Borrower, neither Borrower shall, nor shall it permit

 (i) merge or consolidate with another corporation or entity, or acquire any assets outside the ordinary course of business, except (A) that a subsidiary
may merge or consolidate into another subsidiary or into Parent, and (B) where (1) the aggregate of such transactions do not in the aggregate exceed $2,000,000 (provided however that Borrowers may make a one-time acquisition valued at not more than
$7,000,000 (in addition to the $2,000,000 amount otherwise available) where the consideration is not cash and, if at the time of such proposed transaction there are monetary Obligations outstanding or requested by a Borrower, PFG has reviewed and
consented to the transaction), (2) no Event of Default has occurred and is

Borrower’s monthly cash burn, and (5) such transaction would not result in a decrease of more than 25% of Tangible Net Worth; 
  
 (ii) make any Investments other than Permitted Investments; 
  
 (iii) sell or transfer any Collateral (including without limitation and sale or transfer of Collateral which is then leased back by Borrower except to the

ordinary course of business, (C) the making of Permitted Investments, (D) the granting of Permitted Liens and (E) other sales or transfers of Collateral which in the aggregate do not exceed $250,000 in any fiscal year; 
  
 (iv) store any Inventory or other Collateral with any warehouseman or other

Intellectual Property) become subject to a perfected security interest in favor of PFG; 
  
 (vi) make any loans of any money or other assets, other than Permitted Investments;

or cause a custodian to remain on the premises in exclusive control thereof, without charge for so long as PFG deems it necessary, in its good faith business judgment, in order to complete the enforcement of its rights under this Agreement or any
other agreement; provided, however, that should PFG seek to take possession of any of the Collateral by court process, each Borrower hereby irrevocably waives: (i) any bond and any surety or security relating thereto required by any statute, court

transfer is required; (vi) With respect to any sale of any of the Collateral, PFG may (but is not obligated to) direct any prospective purchaser to ascertain directly from such Borrower any and all information concerning the same. PFG shall be free
to employ other methods of noticing and selling the Collateral, in its discretion, if they are commercially reasonable. 
  
 7.4 Power of Attorney. Upon the occurrence and during the continuance of any Event of Default, without limiting PFG’s other rights and
remedies, each Borrower grants to PFG an irrevocable power of attorney coupled with an interest, authorizing and permitting PFG (acting through any of its employees, attorneys or agents) at any time, at its option, but without obligation, with or
without notice to such Borrower, and at such Borrower’s expense, to do any or all of the following, in such Borrower’s name or otherwise, but PFG agrees that if it exercises any right hereunder, it will do so in good faith and in a
commercially reasonable manner: (a) Execute on behalf of such Borrower any documents that PFG may, in its good faith business judgment, deem advisable in order to perfect and maintain PFG’s security interest in the Collateral, or in order to
exercise a right of such Borrower or PFG, or in order to fully consummate all the transactions contemplated under this Agreement, and all other Loan Documents; (b) Execute on behalf of such Borrower, any invoices relating to any Account, any draft
against any Account Debtor and any notice to any Account Debtor, any proof of claim in bankruptcy, any Notice of Lien, claim of mechanic’s, materialman’s or other lien, or assignment or satisfaction of mechanic’s, materialman’s

possession; (d) Endorse all checks and other forms of remittances received by PFG; (e) Pay, contest or settle any lien, charge, encumbrance, security interest and adverse claim in or to any of the Collateral, or any judgment based thereon, or

and (j) Take any action or pay any sum required of such Borrower pursuant to this Agreement and any other Loan Documents. Any and all reasonable sums paid and any and all reasonable costs, expenses, liabilities, obligations and attorneys’ fees
incurred by PFG with respect to the foregoing shall be added to and become part of the Obligations, shall be payable on demand, and shall bear interest at a rate equal to the highest interest rate applicable to any of the Obligations. In no event
shall PFG’s rights under the foregoing power of attorney or any of PFG’s other rights under this Agreement be deemed to indicate that PFG is in control of the business, management or properties of such Borrower. 
  
 7.5 Application of Proceeds. All proceeds realized as the
result of any sale of the Collateral shall be applied by PFG first to the reasonable costs, expenses, liabilities, obligations and attorneys’ fees incurred by PFG in the exercise of its rights under this Agreement, second to the interest due
upon any of the Obligations, and third to the principal of the Obligations, in such order as PFG shall determine in its sole discretion. Any surplus shall be paid to the applicable Borrower or other persons legally entitled thereto; such Borrower
shall remain liable to PFG for any deficiency. If, PFG, in its good faith business judgment, directly or indirectly enters into a deferred payment or other credit transaction with any purchaser at any sale of Collateral, PFG shall have the option,
exercisable at any time, in its good faith business judgment, of either reducing the Obligations by the principal amount of purchase price or deferring the reduction of the Obligations until the actual receipt by PFG of the cash therefor.

  
 7.6 Remedies Cumulative. In addition to the
rights and remedies set forth in this Agreement, PFG shall have all the other rights and remedies accorded a secured party under the Code and under all other applicable laws, and under any other instrument or agreement now or in the future entered
into between PFG and such Borrower, and all of such rights and remedies are cumulative and none is exclusive. Exercise or partial exercise by PFG of one or more of its rights or remedies shall not be deemed an election, nor bar PFG from subsequent
exercise or partial exercise of any other rights or remedies.

the same degree of care that it exercises with respect to its own proprietary information, to maintain the confidentiality of any and all proprietary, trade secret or confidential information provided to or received by PFG from the Borrowers, which
indicates that it is confidential, including business plans and forecasts, non-public financial information, confidential or secret processes, formulae, devices and contractual information, customer lists, and employee relation matters, provided
that PFG may disclose such information (i) to its officers, directors, employees, attorneys, accountants, affiliates, participants, prospective participants, assignees and prospective assignees, and such other Persons to whom PFG shall at any time
be required to make such disclosure in accordance with applicable law or legal process, and (ii) in its good faith business judgment in connection with the enforcement of its rights or remedies after an Event of Default, or in connection with any
dispute with a Borrower or any other Person relating to a Borrower. The confidentiality agreement in this Section supersedes any prior confidentiality agreement of PFG relating to Borrowers. 
  
 9.2 Interest Computation. In computing interest on the
Obligations, all Payments received after 12:00 Noon, Pacific Time, on any day shall be deemed received on the next Business Day. 
  
 9.3 Payments. All Payments may be applied, and in PFG’s good faith business judgment reversed and re-applied, to the
Obligations, in such order and manner as PFG shall determine in its good faith business judgment. 
  
 9.4 Charges to Accounts. PFG may, in its discretion, require that Borrower pay monetary Obligations in cash to PFG, or charge them to
Borrower’s Loan account, in which event they will bear interest at the same rate applicable to the Loans. 
  
 9.5 Monthly Accountings. PFG shall provide Agent monthly with an account of advances, charges, expenses and payments made pursuant to this
Agreement. Such account shall be deemed correct, accurate and binding on each Borrower 
  

 -15- 








			
	Partners for Growth	 	Loan and Security Agreement

  
 and an account stated (except for
reverses and reapplications of payments made and corrections of errors discovered by PFG), unless a Borrower notifies PFG in writing to the contrary within 60 days after such account is rendered, describing the nature of any alleged errors or
omissions. 
  
 9.6 Notices. All notices to be given
under this Agreement shall be in writing and shall be given either personally, or by reputable private delivery service, or by regular first-class mail, or certified mail return receipt requested, or by fax to the most recent fax number a party has
for the other party (and if by fax, sent concurrently by one of the other methods provided herein), addressed to PFG or a Borrower at the addresses shown in the heading to this Agreement, or at any other address designated in writing by one party to
the other party. All notices shall be deemed to have been given upon delivery in the case of notices personally delivered, or at the expiration of one Business Day following delivery to the private delivery service, or two Business Days following

the final, entire and complete agreement between Borrowers and PFG and supersede all prior and contemporaneous negotiations and oral representations and agreements, all of which are merged and integrated in this Agreement. There are no oral
understandings, representations or agreements between the parties which are not set forth in this Agreement, the Non-Disclosure Agreement, dated as of May 1, 2005,_or in other written agreements signed by the parties in connection herewith.

  
 9.9 Waivers; Indemnity. The failure of PFG at
any time or times to require Borrowers to strictly comply with any of the provisions of this Agreement or any other Loan Document shall not waive or diminish any right of PFG later to demand and receive strict compliance therewith. Any waiver of any
default shall not waive or affect any other default, whether prior or subsequent, and whether or not similar. None of the provisions of this Agreement or any other Loan Document shall be deemed to have been waived by any act or knowledge of PFG or
its agents or employees, but only by a specific written waiver signed by an authorized officer of PFG and delivered to Borrowers. Each Borrower waives the benefit of all statutes of limitations relating to any of the Obligations or this Agreement or
any other Loan Document, and each Borrower waives demand, protest, notice of protest and notice of default or dishonor, notice of payment and nonpayment, release, compromise, settlement, extension or renewal of any commercial paper, instrument,
account, General Intangible, document or guaranty at any time held by PFG on which such Borrower is or may in any way be liable, and notice of any action taken by PFG, unless expressly required by this Agreement. Each Borrower hereby agrees to
indemnify PFG and its affiliates, subsidiaries, parent, directors, officers, employees, agents, and attorneys, and to hold them harmless from and against any and all claims, debts, liabilities, demands, obligations, actions, causes of action,
penalties, costs and expenses (including reasonable attorneys’ fees), of every kind, which they may sustain or incur based upon or arising out of any of the Obligations, or any relationship or agreement between PFG and such Borrower, or any
other matter, relating to such Borrower or the Obligations; provided that this indemnity shall not extend to damages proximately caused by the indemnitee’s own gross negligence or willful misconduct. Notwithstanding any provision in this
Agreement to the contrary, the indemnity agreement set forth in this Section shall survive any termination of this Agreement and shall for all purposes continue in full force and effect. 
  
 9.10 No Liability for Ordinary Negligence. Neither PFG, nor any of its directors, officers, employees, agents,
attorneys or any other Person affiliated with or representing PFG shall be liable for any claims, demands, losses or damages, of any kind whatsoever, made, claimed, incurred or suffered by Borrower or any other party through the ordinary negligence
of PFG, or any of its directors, officers, employees, agents, attorneys or any other Person affiliated with or representing PFG, but nothing herein shall relieve PFG from liability for its own gross negligence or willful misconduct. 
  
 9.11 Amendment. The terms and provisions of this Agreement may
not be waived or amended, except in a writing executed by Borrowers and a duly authorized officer of PFG. 
  
 9.12 Time of Essence. Time is of the essence in the performance by Borrowers of each and every obligation under this Agreement. 

 
 9.13 Attorneys Fees and Costs. Borrowers shall reimburse PFG
for all reasonable attorneys’ fees and all filing, recording, search, title insurance, appraisal, audit, and other reasonable costs incurred by PFG, pursuant to, or in connection with, or relating to this Agreement (whether or not a lawsuit is
filed), including, but not limited to, any reasonable attorneys’ fees and costs PFG incurs in order to do the following: prepare and negotiate this Agreement and all present and future documents relating to this Agreement; obtain legal advice
in connection with this Agreement or Borrowers; enforce, or seek to enforce, any of its rights; prosecute actions against, or defend actions by, Account Debtors; commence, intervene in, or defend any

records; protect, obtain possession of, lease, dispose of, or otherwise enforce PFG’s security interest in, the Collateral; and otherwise represent PFG in any litigation relating to Borrowers. If either PFG or Borrower files any lawsuit against
the other predicated on a breach of this Agreement, the prevailing party in such action shall be entitled to recover its reasonable costs and attorneys’ fees, including (but not limited to) reasonable attorneys’ fees and costs incurred in
the enforcement of, execution upon or defense of any order, decree, award or judgment. All attorneys’ fees and costs to which PFG may be entitled pursuant to this Paragraph shall immediately become part of the Obligations, shall be due on
demand, and shall bear interest at a rate equal to the highest interest rate applicable to any of the Obligations. 
  
 9.14 Benefit of Agreement. The provisions of this Agreement shall be binding upon and inure to the benefit of the respective successors,
assigns, heirs, beneficiaries and representatives of Borrowers and PFG; provided, however, that Borrowers may not assign or transfer any of their rights under this Agreement without the prior written consent of PFG, and any prohibited assignment
shall be void. No consent by PFG to any assignment shall release a Borrower from its liability for the Obligations. 
  
 9.15 Joint and Several Liability. Each Borrower’s liability shall be joint and several, and the compromise of any claim with, or the
release of, any Borrower shall not constitute a compromise with, or a release of, any other Borrower. 
  
 9.16 Limitation of Actions. Any claim or cause of action by any Borrower against PFG, its directors, officers, employees, agents,
accountants or attorneys, based upon, arising from, or relating to this Loan Agreement, or any other Loan Document, or any other transaction contemplated hereby or thereby or relating hereto or thereto, or any other matter, cause or thing
whatsoever, occurred, done, omitted or suffered to be done by PFG, its directors, officers, employees, agents, accountants or attorneys, shall be barred unless asserted by Borrowers by the commencement of an action or proceeding in a court of
competent jurisdiction by the filing of a complaint within one year after the first act, occurrence or omission upon which such claim or cause of action, or any part thereof, is based, and the service of a summons and complaint on an officer of PFG,
or on any other person authorized to accept service on behalf of PFG, within thirty (30) days thereafter. Borrowers agree that such one-year period is a reasonable and sufficient time for Borrowers to investigate and act upon any such claim or cause
of action. The one-year period provided herein shall not be waived, tolled, or extended except by the written consent of PFG in its sole discretion. This provision shall survive any termination of this Loan Agreement or any other Loan Document.

  
 9.17 Paragraph Headings; Construction. Paragraph
headings are only used in this Agreement for convenience. Borrowers and PFG acknowledge that the headings may not describe completely the subject matter of the applicable paragraph, and the headings shall not be used in any manner to construe,
limit, define or interpret any term or provision of this Agreement. This Agreement has been fully reviewed and negotiated between the parties and no uncertainty or ambiguity in any term or provision of this Agreement shall be construed strictly
against PFG or Borrowers under any rule of construction or otherwise. 
  
 9.18 Governing Law; Jurisdiction; Venue. This Agreement and all acts and transactions hereunder and all rights and obligations of PFG and Borrowers shall be governed by the laws of the State of California. As a material part
of the consideration to PFG to enter into this Agreement, each Borrower (i) agrees that all actions and proceedings relating directly or indirectly to this Agreement shall, at PFG’s option, be litigated in courts located within California, and
that the exclusive venue therefor shall be San Francisco County; (ii) consents to the jurisdiction and venue of any such court and consents to service of process in any such action or proceeding by personal delivery or any other method permitted by

Agreement [($27 million x 0.50) - $7 million = $6.5 million].

 These investment guidelines have been adopted by the Board of Directors of Xenogen Corporation in order to establish policy and guidelines for investing
surplus corporate cash, with the goal of capital preservation and liquidity. All investments must be made in compliance with these guidelines, the Investment Company Act of 1940 (the “1940 Act”) and the non-exclusive safe harbor for
research and development companies set forth in rule 3a-8 of the 1940 Act. 
  
 “Surplus cash” is cash not required for short-term debt repayment, working capital, capital investment, or other outstanding near-term financial obligations. 
  
 Objectives 
  
 The key objectives of the company investment policy are the preservation of
capital and maintenance of appropriate short-term liquidity. 
  
 More specifically: 
  

	 	A.	Preserve capital; 

  

	 	B.	Maintain sufficient liquidity to meet forecasted cash needs; 

  

	 	C.	Maintain diversified portfolio of investments in order to minimize the concentration risks; 

  

	 	D.	Maximize yield on investments within the parameters set forth below; 

  

	 	E.	Establish fiduciary control of cash and investments. 

  

	II.	Liquidity Guidelines 

  
 Excess cash is invested with liquidity in mind, and without any loss of principal. 
  
 Daily liquidity is essential; restrictions on liquidity are: 
  

	 	1.	Twice the amount of the monthly burn must be available each business day with no loss of principal. 



	1	Guidelines originally adopted by the Board on July 22, 2003; Amended and Restated Guidelines adopted by the Audit Committee on October 21, 2004









	 	2.	The remainders of the funds are to be invested, consistent with anticipated cash needs, in securities with maturities no longer than 24 months. The weighted-average-maturity cannot
exceed 12-months. Repositioning of these securities before their maturity, generating small gains or losses, is permitted for managing liquidity requirements only. Any loss from such repositioning can only be incurred if the gain in the previous
three months fully offsets this loss. 

  

	III.	Investment Restrictions 

  
 Investments shall be made in the context of the following investment guidelines. 
  

	 	A.	Investment Portfolio 

  

	 	1.	No more than 10 percent of the company’s total assets may consist of investments other than Capital Preservation Investments (defined below). 

  

	 	B.	Capital Preservation Investments 

  

	 	1.	Direct obligations of the U.S. Treasury, including bills, notes, and bonds. 

  

	 	2.	Obligations issued or guaranteed by agencies or instrumentalities of the U.S. government. 

  

	 	3.	Municipal securities (taxable and tax-exempt, when appropriate), including variable rate demand notes and auction rate municipals. 

  

	 	4.	Bank obligations, including certificates of deposit, bank notes, and bankers acceptances. 

  

	 	5.	Corporate obligations, including commercial paper, corporate notes, medium-term notes and corporate bonds. 

  

	 	6.	Repurchase agreements collateralized at a minimum of 102% with U.S. Treasury securities or other securities rated “AAA” or equivalent that would be permitted by this
policy. 

  

	 	7.	Money market funds over $1 billion in assets (must be AAA-rated), with an historically constant dollar net asset value, consisting of acceptable securities as stated above are
appropriate for investing, as long as the fund’s manager has been in business over five years, has name recognition, and has performance that is easily tracked. 

  

	 	8.	U.S. dollar-denominated international corporate debt of all types is acceptable as long as the issuer meets credit rating and marketability guidelines. 

  

	 	9.	Derivative instruments are ineligible as investments. This would cover all investments where the value is based on an underlying variable causing the coupon and/or the maturity
value to be unknown for the life of the security. 








	 	C.	Credit Quality 

  

	 	1.	In all categories described above, the emphasis will be on securities of high credit quality. 

  

	 	2.	Investments which bear a short-term credit rating must be explicitly rated by two of the three following rating services: A1 by Standard & Poor’s, P1 by Moody’s
and/or F-1 by Fitch (no split-rated paper permitted). 

  

	 	3.	Investments which bear a long-term credit rating must be explicitly rated by two of the following rating services: A by Standard & Poor’s, A2 by Moody’s
and/or A by Fitch. 

  

	 	4.	Investments which bear an AAA-rating may only be rated by one of the three rating agencies. 

  

	IV.	Maturities 

  
 The maximum maturity of individual securities in the portfolio may not exceed Twenty-four (24) months. 
  
 The dollar-weighted-average maturity of the portfolio may not exceed twelve
(12) months. 
  
 For securities which have put dates, reset dates
or auction dates, the put date, reset date or auction date will be used, instead of the final maturity date, for maturity guideline purposes. 
  

	V.	Concentration Limits/Restrictions 

  
 There is no limit to the percentage of the portfolio which may be maintained in securities issued by the U.S. Treasury or by its agencies and
instrumentalities. 
  
 No one issuer or group of issuers from the
same holding company is to exceed 10% of the portfolio or $1.0 million, whichever is greater of the portfolio at time of purchase, with the exception of Government securities. 
  
 AND, no more than 10% of the total issue size outstanding at time of purchase. 
  
 Any investment in common stocks, preferred stocks, options (put or calls),
commodities, foreign securities, futures or mutual funds whose underlying securities are not considered Capital Preservation Investments must comply with Part III.A of this policy. 
  

	VI.	Investment Performance 

  
 The company shall review the performance of the selected investment-banking group on quarterly basis. The investment banks will issue separate quarterly
investment performance analysis using time-weighted measures. 
  
 The net income derived from investments for the last four fiscal quarters combined may not exceed twice the amount of the company’s research and development expenses for the same period. 






 Expenses for investment advisory and management activities, investment research and custody for the last
four fiscal quarters combined may not exceed five percent of the company’s total expenses for the same period. 
  

	VII.	Marketability 

  
 All securities are to be purchased through investment banking and brokerage firms of high quality and reputation, with a history of making markets for the
securities in which we invest. In the unlikely event that securities must be sold before their maturity, the securities must be easily re-marketed. To accomplish this, the securities must be conventional “products” with strong name
recognition. 
  

	VIII.	Trading Guidelines 

  
 Normal investing practice is to reinvest the funds on the day a security matures, to minimize lost interest. A daily transaction log is to be maintained
and available for review at any time. All trading firms must generate a hard copy document for each transaction which is mailed to us on a timely basis, and then matched to the transaction log. Quarterly summaries of our investment holdings and cash
usage are to be made available for Board review. 
  

	IX.	Communication 

  
 The investment manager will contact the Chief Financial Officer immediately upon the occurrence of any of the following events: 
  

	 	A.	An issuer is placed on “CreditWatch” with Negative Implications” and/or on “Negative Outlook” whereby any whereby any potential action could result in a
credit rating cut; 

  

	 	B.	A decline in the issuer’s credit rating below the minimum credit quality standards stated in this Investment Policy. 

  

	 	C.	Research and development expenses for the last four fiscal quarters combined are no longer a substantial percentage of the company’s total expenses for the same period.


  

	 	D.	The company is not in compliance with any of these guidelines. 

  

	X.	Safekeeping 

  
 Assets/investment securities are to be held in segregated bank account; they cannot be co-mingled. Assets/investment securities can be held by the
investment manager as long as the manager’s minimum long-term rating is A2 by Moody’s and A by S&P. 







	XI.	Fiduciary Discretion 

  
 The Chief Financial Officer or other individual appointed by the Board and his/her authorized employees are responsible for securing and managing
investments and cash for operations. These individuals have full discretion to invest any excess capital subject to strict adherence to these guidelines. These guidelines and the performance of the investments are to be reviewed periodically with
the Board of Directors and only then can guideline revisions be made.
