LOAN AND SECURITY AGREEMENT

THIS LOAN AND SECURITY AGREEMENT (this “Agreement”) dated as of the Effective Date between SILICON VALLEY BANK, a California corporation (“Bank”), and LUCA TECHNOLOGIES INC., a Delaware corporation (“Borrower”), provides the terms on which Bank shall lend to Borrower and Borrower shall repay Bank. The parties agree as follows:

1.	ACCOUNTING AND OTHER TERMS

Accounting terms not defined in this Agreement shall be construed following GAAP. Calculations and determinations must be made following GAAP. Capitalized terms not otherwise defined in this Agreement shall have the meanings set forth in Section 13. All other terms contained in this Agreement, unless otherwise indicated, shall have the meaning provided by the Code to the extent such terms are defined therein.

2.	LOAN AND TERMS OF PAYMENT

2.1 Promise to Pay. Borrower hereby unconditionally promises to pay Bank the outstanding principal amount of all Credit Extensions and accrued and unpaid interest thereon as and when due in accordance with this Agreement.

2.1.1 Advances.

(a) Availability. Subject to the terms and conditions of this Agreement, from the Effective Date through April 30, 2009, Bank shall make Advances not exceeding the Availability Amount. Each Advance will be at least $250,000. Any Advances that are outstanding on April 30, 2009 are payable in thirty-six (36) consecutive equal monthly installments of principal plus accrued interest, beginning on May 1, 2009, and continuing on the same day of each month thereafter through the Maturity Date. On the Maturity Date, the entire unpaid principal balance and all outstanding interest shall be immediately due and payable.

(b) Prepayment. Borrower may prepay all or any portion of the Advances without premium or penalty, but may not re-borrow any Advances.

2.2 Payment of Interest on the Credit Extensions.

(a) Interest Rate. Subject to Section 2.2(b), the outstanding principal amount of the Advances shall accrue interest at a floating rate per annum equal to the Prime Rate through April 30, 2009, on which date the interest rate will be fixed at a rate per annum equal to the Prime Rate then in effect.

(b) Default Rate. Immediately upon the occurrence and during the continuance of an Event of Default, Obligations shall bear interest at a rate per annum which is five percentage points above the rate effective immediately before the Event of Default (the “Default Rate”). Payment or acceptance of the increased interest rate provided in this Section 2.2(b) is not a permitted alternative to timely payment and shall not constitute a waiver of any Event of Default or otherwise prejudice or limit any rights or remedies of Bank.

(c) Adjustment to Interest Rate. Changes to the interest rate of any Credit Extension shall be effective on the effective date of any change to the Prime Rate and to the extent of any such change.

(d) 360-Day Year. Interest shall be computed on the basis of a 360-day year for the actual number of days elapsed.

(e) Debit of Accounts. Bank may debit any of Borrower’s deposit accounts, including the Designated Deposit Account (but excluding deposit accounts exclusively used for payroll, payroll taxes and other employee wage and benefit payments to or for the benefit of Borrower’s employees and identified to Bank by Borrower as such), for principal and interest payments or any other amounts Borrower owes Bank under the Loan Documents when due. These debits shall not constitute a set-off.

(f) Payments. Unless otherwise provided, interest is payable monthly on the first calendar day of each month following the Effective Date. Payments of principal and/or interest received after 12:00 p.m. Pacific time are considered received at the opening of business on the next Business Day. When a payment is due on a day that is not a Business Day, the payment is due the next Business Day and additional fees or interest, as applicable, shall continue to accrue.

2.3 Fees. Borrower shall pay to Bank:

(a) Commitment Fee. On the Effective Date, a fully earned, non-refundable commitment fee of $3,000.

(b) Bank Expenses. All Bank Expenses (including reasonable attorneys’ fees and expenses, for documentation and negotiation of this Agreement up to an aggregate amount of $7,000) incurred through and after the Effective Date, when due.

3.	CONDITIONS OF LOANS

3.1 Conditions Precedent to Initial Credit Extension.

(e) Bank shall have received certified copies, dated as of a recent date, of financing statement searches, as Bank shall request, accompanied by written evidence (including any UCC termination statements) that the Liens indicated in any such financing statements either constitute Permitted Liens or have been or, in connection with the initial Credit Extension, will be terminated or released;

(a) except as otherwise provided in Section 3.4, timely receipt of an executed Payment/Advance Form;

(b) the representations and warranties in Section 5 shall be true in all material respects on the date of the Payment/Advance Form and on the Funding Date of each Credit Extension; provided, however, that such materiality qualifier shall not be applicable to any representations and warranties that already are qualified or

-2-

modified by materiality in the text thereof; and provided, further that those representations and warranties expressly referring to a specific date shall be true in all material respects as of such date, and no Default or Event of Default shall have occurred and be continuing or result from the Credit Extension. Each Credit Extension is Borrower’s representation and warranty on that date that the representations and warranties in Section 5 are true in all material respects on the date of such Credit Extension; provided, however, that such materiality qualifier shall not be applicable to any representations and warranties that already are qualified or modified by materiality in the text thereof; and provided, further that those representations and warranties expressly referring to a specific date shall be true in all material respects as of such date; and

3.3 Covenant to Deliver.

Borrower agrees to deliver to Bank each item required to be delivered to Bank under this Agreement as a condition to any Credit Extension. Borrower expressly agrees that the extension of a Credit Extension prior to the receipt by Bank of any such item shall not constitute a waiver by Bank of Borrower’s obligation to deliver such item, and any such extension in the absence of a required item shall be in Bank’s sole discretion.

3.4 Procedures for Borrowing.

Subject to the prior satisfaction of all other applicable conditions to the making of an Advance set forth in this Agreement, to obtain an Advance, Borrower shall notify Bank (which notice shall be irrevocable) by electronic mail, facsimile, or telephone by 12:00 p.m. Pacific time on the Funding Date of the Advance. Together with any such electronic or facsimile notification, Borrower shall deliver to Bank by electronic mail or facsimile a completed Payment/Advance Form executed by a Responsible Officer or his or her designee. Bank may rely on any telephone notice given by a person whom Bank believes is a Responsible Officer or designee. Bank shall credit Advances to the Designated Deposit Account. Bank may make Advances under this Agreement based on instructions from a Responsible Officer or his or her designee or without instructions if the Advances are necessary to meet Obligations which have become due.

4.	CREATION OF SECURITY INTEREST

4.1 Grant of Security Interest. To secure the payment and performance in full of all of the Obligations, Borrower grants Bank a continuing security interest in, and pledges to Bank, all of Borrower’s right, title and interest in, to and under the Collateral, wherever located, whether now owned or hereafter acquired or arising, and all proceeds and products thereof. Borrower represents, warrants, and covenants that the security interest granted herein is and shall at all times continue to be a first priority perfected security interest in the Collateral (subject only to Permitted Liens that may have superior priority to Bank’s Lien under this Agreement). If Borrower shall acquire a commercial tort claim, Borrower shall promptly notify Bank in a writing signed by Borrower of the general details thereof and, if requested by Bank, grant to Bank in such writing a security interest therein and in the proceeds thereof, all upon the terms of this Agreement, with such writing to be in form and substance reasonably satisfactory to Bank.

If this Agreement is terminated, Bank’s Lien in the Collateral shall continue until the Obligations (other than inchoate indemnity obligations) are repaid in full in cash. Upon payment in full in cash of the Obligations (other than inchoate indemnity obligations) and at such time as Bank’s obligation to make Credit Extensions under this Agreement has terminated, Bank’s Lien in the Collateral shall automatically terminate and all rights therein shall revert to Borrower and Bank shall, at Borrower’s sole cost and expense deliver such documents and make such filings as Bank shall reasonably request to evidence such termination.

4.2 Authorization to File Financing Statements. Borrower authorizes Bank to file financing statements with all appropriate jurisdictions to perfect or protect Bank’s interest or rights hereunder.

-3-

5.	REPRESENTATIONS AND WARRANTIES

Except as disclosed in the Perfection Certificate, Borrower represents and warrants as follows:

5.1 Due Organization and Authorization. Borrower is duly existing and in good standing in its jurisdiction of formation and is qualified and licensed to do business and is in good standing in any jurisdiction in which the conduct of its business or its ownership of property requires that it be qualified except where the failure to do so could not reasonably be expected to have a material adverse effect on Borrower’s business. In connection with this Agreement, Borrower has delivered to Bank a completed certificate entitled “Perfection Certificate”. Borrower represents and warrants to Bank that, as of the Effective Date: (a) Borrower’s exact legal name is that indicated on the Perfection Certificate and on the signature page hereof; (b) Borrower is an organization of the type and is organized in the jurisdiction set forth in the Perfection Certificate; (c) the Perfection Certificate accurately sets forth Borrower’s organizational identification number or accurately states that Borrower has none; (d) the Perfection Certificate accurately sets forth Borrower’s place of business, or, if more than one, its chief executive office as well as Borrower’s mailing address (if different than its chief executive office); (e) Borrower (and each of its predecessors) has not, in the five (5) years preceding the Effective Date, changed its state of formation, organizational structure or type, or any organizational number assigned by its jurisdiction (unless included on the Perfection Certificate); and (f) all other information set forth on the Perfection Certificate pertaining to Borrower and each of its Subsidiaries is accurate and complete in all material respects. If Borrower is not now a Registered Organization but later becomes one, Borrower shall promptly notify Bank of such occurrence and provide Bank with Borrower’s organizational identification number.

The execution, delivery and performance by Borrower of the Loan Documents and the Warrant have been duly authorized by all requisite corporate action, and do not conflict with Borrower’s organizational documents, nor constitute an event of default under any material agreement by which Borrower is bound. Borrower is not in default under any agreement to which it is a party or by which it is bound in which the default could have a material adverse effect on Borrower’s business.

5.2 Collateral. Borrower has good title to, or has sufficient rights by license or otherwise in, and the power to grant a security interest in each item of the Collateral upon which it purports to grant a Lien hereunder, free and clear of any and all Liens except Permitted Liens. Borrower has no deposit accounts other than the deposit accounts with Bank, the deposit accounts, if any, described in the Perfection Certificate delivered to Bank in connection herewith, or of which Borrower has given Bank notice (such notice shall be deemed to automatically update the disclosure regarding Deposit Accounts in the Perfection Certificate) and taken such actions as are necessary to give Bank a perfected security interest therein.

The Collateral is not in the possession of any third party bailee (such as a warehouse) except as otherwise provided in the Perfection Certificate or as Borrower has given notice pursuant to Section 7.2 (such notice shall be deemed to automatically update such disclosure in the Perfection Certificate). None of the material components of the Collateral shall be maintained at locations other than as provided in the Perfection Certificate, as Borrower has given Bank notice pursuant to Section 7.2 (such notice shall be deemed to automatically update such disclosure in the Perfection Certificate). In the event that Borrower, after the date hereof, intends to store or otherwise deliver any material portion of the Collateral to a bailee, then Borrower will first receive the written consent of Bank and such bailee must execute and deliver a bailee agreement in form and substance satisfactory to Bank in its sole discretion.

5.3 Accounts Receivable. For any Accounts, all statements made and all unpaid balances appearing in all invoices, instruments and other documents evidencing such Accounts are and shall be true and correct in all material respects and all such invoices, instruments and other documents, and all of Borrower’s Books are genuine and in all material 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 Borrower’s knowledge, all signatures and endorsements on all documents, instruments, and agreements relating to all Accounts are genuine, and all such documents, instruments and agreements are legally enforceable in accordance with their terms.

5.4 Litigation. Except as disclosed to Bank pursuant to Section 6.2, there are no actions or proceedings pending or, to the knowledge of the Responsible Officers, threatened in writing by or against Borrower

-4-

or any of its Subsidiaries which could reasonably be expected to result in liability of more than One Hundred Thousand Dollars ($100,000).

5.5 No Material Deviation in Financial Statements. The consolidated financial statements for Borrower and any of its Subsidiaries delivered to Bank fairly present in all material respects Borrower’s consolidated financial condition and Borrower’s consolidated results of operations as of the dates, and for the periods, indicated therein, subject in the case of the unaudited financial statements to normal year-end audit adjustments and matters that would be disclosed in footnotes thereto. As of the Effective Date, there has not been any material deterioration in Borrower’s consolidated financial condition since the date of the most recent financial statements submitted to Bank.

5.6 Solvency. The fair salable value of Borrower’s assets (including goodwill minus disposition costs) exceeds the fair value of its liabilities; Borrower is not left with unreasonably small capital after the transactions in this Agreement; and Borrower is able to pay its debts (including trade debts) as they mature.

5.7 Regulatory Compliance. Borrower is not an “investment company” or a company “controlled” by an “investment company” under the Investment Company Act. Borrower is not engaged as one of its important activities in extending credit for margin stock (under Regulations T and U of the Federal Reserve Board of Governors). Borrower is in compliance in all material respects with the Federal Fair Labor Standards Act. Borrower is not in violation of any laws, ordinances or rules, the violation of which could reasonably be expected to have a material adverse effect on its business. None of Borrower’s or any of its Subsidiaries’ properties or assets has been used by Borrower or any Subsidiary or, to the best of Borrower’s knowledge, by previous Persons, in disposing, producing, storing, treating, or transporting any hazardous substance other than legally. Borrower and each of its Subsidiaries have obtained all consents, approvals and authorizations of, made all declarations or filings with, and given all notices to, all government authorities that are necessary to continue its business as currently conducted, except, where failure to do so could not reasonably, in each such case, be expected to result in a material adverse effect on the Borrower’s business.

5.8 Subsidiaries; Investments. Borrower does not own any stock, partnership interest or other equity securities except for Permitted Investments. As of the Closing Date, Patriot is the sole Subsidiary of Borrower.

5.9 Tax Returns and Payments; Pension Contributions. Borrower has timely filed all required material tax returns and reports, and Borrower has timely paid all material foreign, federal, state and local taxes, assessments, deposits and contributions owed by Borrower. Borrower may defer payment of any contested taxes, provided that Borrower (a) in good faith contests its obligation to pay the taxes by appropriate proceedings promptly and diligently instituted and conducted and (b) with respect to contested amounts in excess of One Hundred Thousand Dollars ($100,000), notifies Bank in writing of the commencement of, and any material development in, the proceedings and posts bonds or takes any other steps required to prevent the governmental authority levying such contested taxes from obtaining a Lien upon any of the Collateral that is other than a “Permitted Lien”. Except as disclosed to Bank in writing, Borrower is unaware of any claims or adjustments proposed for any of Borrower’s prior tax years which could result in additional taxes becoming due and payable by Borrower. Borrower has paid all amounts necessary to fund all present pension, profit sharing and deferred compensation plans in accordance with their terms, and Borrower has not withdrawn from participation in, and has not permitted partial or complete termination of, or permitted the occurrence of any other event with respect to, any such plan which could reasonably be expected to result in any liability of Borrower, including any liability to the Pension Benefit Guaranty Corporation or its successors or any other governmental agency.

5.10 Use of Proceeds. Borrower shall use the proceeds of the Credit Extensions solely as working capital and to fund its general business requirements and not for personal, family, household or agricultural purposes.

5.11 Full Disclosure. No written representation, warranty or other statement of Borrower in any certificate or written statement given to Bank, as of the date such representations, warranties, or other statements were made, taken together with all such written certificates and written statements given to Bank, contains any untrue statement of a material fact or omits to state a material fact necessary to make the statements contained in the certificates or statements not misleading (it being recognized by Bank that the projections and forecasts provided by

-5-

Borrower in good faith and based upon reasonable assumptions are not viewed as facts and that actual results during the period or periods covered by such projections and forecasts may differ from the projected or forecasted results).

6.	AFFIRMATIVE COVENANTS

So long as any Obligation shall remain unpaid (other than inchoate indemnity obligations) or Bank shall have any commitment to make Credit Extensions hereunder, Borrower shall do all of the following:

6.1 Government Compliance. Except as permitted by Section 7.3, maintain its and all its Subsidiaries’ legal existence and good standing in their respective jurisdictions of formation and maintain qualification in each jurisdiction in which the failure to so qualify would reasonably be expected to have a material adverse effect on Borrower’s business or operations. Borrower shall comply, and have each Subsidiary comply, with all laws, ordinances and regulations to which it is subject, noncompliance with which could have a material adverse effect on Borrower’s business.

6.2 Financial Statements, Reports, Certificates.

(a) Deliver to Bank: (i) as soon as available, but no later than thirty-five (35) days after the last day of each month before the first anniversary of the Closing Date, and thirty (30) days after the last day of each month thereafter, a company prepared consolidated balance sheet and income statement covering the consolidated operations of Borrower and its consolidated Subsidiaries during the period certified by a Responsible Officer and in a form acceptable to Bank; (ii) as soon as available, but no later than one hundred eighty (180) days after the last day of Borrower’s fiscal year, audited consolidated financial statements prepared under GAAP, consistently applied, together with an unqualified opinion (other than a “going concern” qualification) on the financial statements from an independent certified public accounting firm acceptable to Bank in its reasonable discretion; (iii) within five (5) days of delivery, copies of all statements, reports and notices made available generally to Borrower’s security holders or to any holders of Subordinated Debt, (iv) in the event that Borrower becomes subject to the reporting requirements under the Securities Exchange Act of 1934, as amended, within five (5) days of filing, all reports on Form 10-K, 10-Q and 8-K filed with the Securities and Exchange Commission or a link thereto on Borrower’s or another website on the Internet; (v) a prompt report of any legal actions pending or threatened in writing against Borrower or any of its Subsidiaries that could reasonably be expected to result in damages or costs to Borrower or any of its Subsidiaries of One Hundred Thousand Dollars ($100,000) or more; (vi) prompt notice of an event that materially and adversely affects the value of the intellectual property that is material to the business of Borrower; (vii) annual financial projections commensurate with those provided to the Borrower’s venture capital investors, approved by the Borrower’s board of directors promptly after approval of the same by Borrower’s board of directors but no later than February 15 of each fiscal year; and (viii) other financial information reasonably requested by Bank.

(b) Allow Bank to audit Borrower’s Collateral at Borrower’s expense, provided that so long as no Event of Default has occurred and is continuing, Bank shall not exercise such rights more often than one time during any calendar year.

6.3 Inventory; Returns. Keep all material Inventory in good and marketable condition, free from material defects. Returns and allowances between Borrower and its Account Debtors shall follow Borrower’s customary practices. Borrower must promptly notify Bank of all returns, recoveries, disputes and claims that involve more than One Hundred Thousand Dollars ($100,000).

6.4 Taxes; Pensions. Make, and cause each of its Subsidiaries to make, timely payment of all material foreign, federal, state, and local taxes or assessments (other than taxes and assessments which Borrower is contesting pursuant to the terms of Section 5.9 hereof) and shall deliver to Bank, on demand, appropriate certificates attesting to such payments, and pay all amounts necessary to fund all present pension, profit sharing and deferred compensation plans in accordance with their terms.

6.5 Insurance. Keep its business and the Collateral insured for risks and in amounts standard for companies in Borrower’s industry and location and as Bank may reasonably request. Insurance policies shall be in a form, with companies, and in amounts that are reasonably satisfactory to Bank. All property policies shall have a lender’s loss payable endorsement showing Bank as an additional loss payee and waive subrogation against Bank, and all liability policies shall show, or have endorsements showing, Bank as an additional insured. All policies (or

-6-

the loss payable and additional insured endorsements) shall provide that the insurer must give Bank at least twenty (20) days notice before canceling, amending, or declining to renew its policy. At Bank’s request, Borrower shall deliver certified copies of policies and evidence of all premium payments. Proceeds payable under any casualty policy shall be payable to Borrower for repair or replacement of the damaged or destroyed property so long as no Event of Default is outstanding; provided, however, that if an Event of Default is outstanding, at Bank’s option, such proceeds may be payable to Bank on account of the Obligations. If Borrower fails to obtain insurance as required under this Section 6.5 or to pay any amount or furnish any required proof of payment to third persons and Bank, Bank may, after reasonable prior written notice to Borrower, make all or part of such payment or obtain such insurance policies required in this Section 6.5, and take any action under the policies Bank reasonably deems prudent.

6.6 Operating Accounts.

(a) Maintain its primary operating, depository and securities accounts with Bank and Bank’s affiliates, provided Borrower may maintain certificates of deposit and other securities with US Bank until they mature, at which time Borrower will deposit the proceeds of those securities with Bank, and provided further that Borrower shall deliver a securities account control agreement to Bank in form reasonably acceptable to Bank if any securities remain invested with US Bank 90 days after the Effective Date.

(b) Provide Bank five (5) days prior written notice before establishing any Collateral Account at or with any bank or financial institution other than Bank or its Affiliates. In addition, for each Collateral Account that Borrower at any time maintains, Borrower shall cause the applicable bank or financial institution (other than Bank) at or with which any Collateral Account is maintained to execute and deliver a Control Agreement or other appropriate instrument with respect to such Collateral Account to perfect Bank’s Lien in such Collateral Account in accordance with the terms hereunder. The provisions of the previous sentence shall not apply to deposit accounts exclusively used for payroll, payroll taxes and other employee wage and benefit payments to or for the benefit of Borrower’s employees and identified to Bank by Borrower as such.

6.7 Protection of Intellectual Property Rights. Borrower shall: (a) protect, defend and maintain the validity and enforceability of its intellectual property except where Borrower in the exercise of its business judgment deems it in its best interest not to do so; (b) promptly advise Bank in writing of material infringements of its intellectual property; and (c) not allow any intellectual property material to Borrower’s business to be abandoned, forfeited or dedicated to the public without Bank’s written consent except where Borrower in the exercise of its business judgment deems it in its best interest to do so.

8.2 Covenant Default.

(a) Borrower fails to perform any obligation in Sections 6.2 or 6.6 or violates any covenant in Section 7; or

(b) Borrower fails to perform, keep, or observe any other term, provision, condition, covenant or agreement contained in this Agreement, any Loan Documents, and as to any default (other than those specified elsewhere in this Section 8) under such other term, provision, condition, covenant or agreement that can be cured, has failed to cure the default within twenty (20) days after Borrower receives written notice thereof from Bank or, if earlier, within twenty (20) days after Borrower reasonably should have known of such default or non-performance; provided, however, that if the default cannot by its nature be cured within the twenty (20) day period or cannot after diligent attempts by Borrower be cured within such twenty (20) day period, and such default is likely

-9-

to be cured within a reasonable time, then Borrower shall have an additional period (which shall not in any case exceed thirty (30) days) to attempt to cure such default, and within such reasonable time period the failure to cure the default shall not be deemed an Event of Default (but no Credit Extensions shall be made during such cure period). Grace periods provided under this section shall not apply to any other covenants set forth in subsection (a) above;

8.3 Investor Support. Bank reasonably and in good faith determines that Borrower does not have Investor Support.

8.4 Attachment. (a) Any material portion of Borrower’s assets is attached, seized, levied on, or comes into possession of a trustee or receiver and the attachment, seizure or levy is not removed, rescinded or discharged within ten (10) days; (b) the service of process upon Bank seeking to attach, by trustee or similar process, any funds of Borrower or of any Restricted Subsidiary on deposit with Bank that is not rescinded or dismissed within ten (10) days; (c) Borrower is enjoined, restrained, or prevented by court order from conducting a material part of its business; (d) a judgment or other claim in excess of One Hundred Thousand Dollars ($100,000) becomes a Lien on any of Borrower’s assets and such lien or encumbrance has not been released or removed within ten (10) days of attaching; or (e) a notice of lien, levy, or assessment is filed against any of Borrower’s assets by any government agency and not paid within thirty (30) days after Borrower receives notice. These are not Events of Default if stayed or if a bond is posted pending contest by Borrower (but no Credit Extensions shall be made during the cure period);

8.5 Insolvency. Borrower is unable to pay its debts (including trade debts) as they become due; (b) Borrower begins an Insolvency Proceeding; or (c) an Insolvency Proceeding is begun against Borrower and not dismissed or stayed within forty-five (45) days (but no Credit Extensions shall be made while of any of the conditions described in clause (a) exist and/or until any Insolvency Proceeding is dismissed);

8.6 Other Agreements. There is a default in any agreement to which Borrower is a party with a third party or parties relating to any Indebtedness (other than the Obligations or unsecured Indebtedness to trade creditors incurred in the ordinary course of business) in the outstanding principal amount in excess of One Hundred Thousand Dollars ($100,000) in the aggregate, which default is not waived or cured within any applicable grace or cure period and results in a right by such third party or parties, whether or not exercised, to accelerate the maturity of such Indebtedness;

8.7 Judgments. A judgment or judgments for the payment of money in an amount, individually or in the aggregate, of at least One Hundred Thousand Dollars ($100,000) (not covered by independent third-party insurance) shall be rendered against Borrower and shall remain unsatisfied and unstayed for a period of thirty (30) days after the entry thereof (provided that no Credit Extensions will be made prior to the satisfaction or stay of such judgment);

8.8 Misrepresentations. Borrower or any Person acting for Borrower makes any representation, warranty, or other statement now or later in this Agreement, any Loan Document or in any writing delivered to Bank or to induce Bank to enter this Agreement or any Loan Document, and such representation, warranty, or other statement is incorrect in any material respect when made; or

8.9 Subordinated Debt. A default or breach occurs under any agreement between Borrower and any creditor of Borrower that signed a subordination, intercreditor, or other similar agreement with Bank, or any creditor that has signed such an agreement with Bank breaches any material terms of such agreement, and in each such case, the default or breach is not waived or cured within any applicable grace or cure period.

9.	BANK’S RIGHTS AND REMEDIES

9.1 Rights and Remedies. While an Event of Default occurs and continues Bank may, without notice or demand, do any or all of the following:

(a) declare all Obligations immediately due and payable (but if an Event of Default described in Section 8.5 occurs all Obligations are immediately due and payable without any action by Bank);

-10-

(b) stop advancing money or extending credit for Borrower’s benefit under this Agreement or under any other agreement between Borrower and Bank;

(c) settle or adjust disputes and claims directly with Account Debtors for amounts on terms and in any order that Bank reasonably considers advisable, notify any Person owing Borrower money of Bank’s security interest in such funds, and verify the amount of such account;

(d) make any payments and do any acts it considers necessary or reasonable to protect the Collateral and/or its security interest in the Collateral. Borrower shall assemble the Collateral if Bank requests and make it available at a place or places designated by Bank which are reasonably convenient to Bank and Borrower. Bank may enter premises where the Collateral is located, take and maintain possession of any part of the Collateral, and pay, purchase, contest, or compromise any Lien which appears to be prior or superior to its security interest (other than Permitted Liens that may have superior priority to Bank’s Lien under this Agreement) and pay all expenses incurred in connection therewith. Borrower grants Bank a license to enter and occupy any of its premises, without charge, to exercise any of Bank’s rights or remedies (provided, that such license shall only be granted with respect to premises that are not owned by Borrower to the extent such license does not violate or breach the lease or other agreement pursuant to which Borrower has a right to use and occupy such premises);

(e) apply to the Obligations any (i) balances and deposits of Borrower it holds, or (ii) any amount held by Bank owing to or for the credit or the account of Borrower (Bank agrees to notify Borrower promptly after any such application, provided that the failure to give such notice shall not affect the validity of such application);

(f) ship, reclaim, recover, store, finish, maintain, repair, prepare for sale, advertise for sale, and sell the Collateral. Except to the extent that such use, assignment, license or sublicense is expressly prohibited under a license agreement and would result in a breach under such agreement for which such agreement would reasonably be expected to be terminated by such licensor, upon the occurrence of such an Event of Default and the exercise of its rights under this Section 9.1(f), Bank is hereby granted a non-exclusive, royalty-free license or other right to use, without charge and solely pursuant to this Section 9.1, Borrower’s labels, patents, copyrights, mask works, rights of use of any name, trade secrets, trade names, trademarks, service marks, and advertising matter, or any similar property as it pertains to the Collateral, solely as necessary in completing production of, advertising for sale, and selling any Collateral and, solely in connection with Bank’s exercise of its rights under this Section, Borrower’s rights under all licenses and all franchise agreements inure to Bank’s benefit;

(g) place a “hold” on any account maintained with Bank (excluding accounts exclusively used for payroll, payroll taxes and other employee wage and benefit payments to or for the benefit of Borrower’s employees and identified to Bank by Borrower as such) and/or deliver a notice of exclusive control, any entitlement order, or other directions or instructions pursuant to any Control Agreement or similar agreements providing control of any Collateral; and

(h) exercise all rights and remedies available to Bank under the Loan Documents or at law or equity, including all remedies provided under the Code (including disposal of the Collateral pursuant to the terms thereof).

9.2 Power of Attorney. Borrower hereby irrevocably appoints Bank as its lawful attorney-in-fact, exercisable only upon the occurrence and during the continuance of an Event of Default, to: (a) endorse Borrower’s name on any checks or other forms of payment or security that may come into Bank’s possession; (b) sign Borrower’s name on any invoice or bill of lading for any Account or drafts against Account Debtors; (c) settle and adjust disputes and claims about the Accounts directly with Account Debtors, for amounts and on terms Bank determines reasonable; (d) make, settle, and adjust all claims under Borrower’s insurance policies; (e) pay, contest or settle any Lien, charge, encumbrance, security interest, and adverse claim in or to the Collateral, or any judgment based thereon, or otherwise take any action to terminate or discharge the same; (f) transfer the Collateral into the name of Bank or a third party as the Code permits; and (g) sign Borrower’s name on any documents necessary to perfect or continue the perfection of any security interest. Bank’s foregoing appointment as Borrower’s attorney in fact, and all of Bank’s rights and powers, coupled with an interest, are irrevocable until all Obligations (other than inchoate indemnity obligations) have been fully repaid and performed and Bank’s obligation to provide Credit Extensions terminates.

-11-

9.3 Accounts Verification; Collection. During the existence of an Event of Default, Bank may notify any Person owing Borrower money of Bank’s security interest in such funds and verify the amount of such account. During the existence of an Event of Default, any amounts received by Borrower shall be held in trust by Borrower for Bank, and, if requested by Bank, Borrower shall immediately deliver such receipts to Bank in the form received from the Account Debtor, with proper endorsements for deposit.

9.4 Protective Payments. If Borrower fails to obtain the insurance called for by Section 6.5 or fails to pay any premium thereon or fails to pay any other amount which Borrower is obligated to pay under this Agreement or any other Loan Document, Bank may, after reasonable written notice to Borrower, obtain such insurance or make such payment. All amounts so paid by Bank are Bank Expenses, shall be due and payable within five (5) Business Days following demand, and, to the extent not paid when due, shall bear interest at the then highest applicable rate hereinabove provided, and shall be secured by the Collateral. No payments by Bank are deemed an agreement to make similar payments in the future or Bank’s waiver of any Event of Default.

9.5 Application of Payments and Proceeds. Unless an Event of Default has occurred and is continuing, Bank shall apply any funds in its possession, whether from Borrower account balances, payments, or proceeds realized as the result of any collection of Accounts or other disposition of the Collateral, first, to Bank Expenses, including without limitation, the reasonable costs, expenses, liabilities, obligations and attorneys’ fees incurred by Bank 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 and any applicable fees and other charges, in such order as Bank shall determine in its sole discretion. Any surplus shall be paid to Borrower or other Persons legally entitled thereto; Borrower shall remain liable to Bank for any deficiency. If an Event of Default has occurred and is continuing, Bank may apply any funds in its possession, whether from Borrower account balances, payments, proceeds realized as the result of any collection of Accounts or other disposition of the Collateral, or otherwise, to the Obligations in such order as Bank shall determine in its sole discretion. Any surplus shall be paid to Borrower or other Persons legally entitled thereto; Borrower shall remain liable to Bank for any deficiency. If Bank, 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 in connection with exercise of Bank’s rights and remedies during the continuance of an Event of Default, Bank shall have the option, exercisable at any time, of either reducing the Obligations by the principal amount of the purchase price or deferring the reduction of the Obligations until the actual receipt by Bank of cash therefor.

9.6 Bank’s Liability for Collateral. So long as Bank complies with reasonable banking practices and the Code regarding the safekeeping of the Collateral in the possession or under the control of Bank, Bank shall not be liable or responsible for: (a) the safekeeping of the Collateral; (b) any loss or damage to the Collateral; (c) any diminution in the value of the Collateral; or (d) any act or default of any carrier, warehouseman, bailee, or other Person. Borrower bears all risk of loss, damage or destruction of the Collateral.

9.7 No Waiver; Remedies Cumulative. Bank’s failure, at any time or times, to require strict performance by Borrower of any provision of this Agreement or any other Loan Document shall not waive, affect, or diminish any right of Bank thereafter to demand strict performance and compliance herewith or therewith. No waiver hereunder shall be effective unless signed by Bank and then is only effective for the specific instance and purpose for which it is given. Bank’s rights and remedies under this Agreement and the other Loan Documents are cumulative. Bank has all rights and remedies provided under the Code, by law, or in equity. Bank’s exercise of one right or remedy is not an election, and Bank’s waiver of any Event of Default is not a continuing waiver. Bank’s delay in exercising any remedy is not a waiver, election, or acquiescence.

9.8 Demand Waiver. Except as expressly provided for herein or in any other Loan Document, Borrower waives demand, notice of default or dishonor, notice of payment and nonpayment, notice of any default, nonpayment at maturity, release, compromise, settlement, extension, or renewal of accounts, documents, instruments, chattel paper, and guarantees held by Bank on which Borrower is liable.

10.

CHOICE OF LAW, VENUE, JURY TRIAL WAIVER AND JUDICIAL REFERENCE

California law governs the Loan Documents without regard to principles of conflicts of law. Borrower and Bank each submit to the exclusive jurisdiction of the State and Federal courts in Santa Clara County, California; provided, however, that nothing in this Agreement shall be deemed to operate to preclude Bank from bringing suit or taking other legal action in any other jurisdiction to realize on the Collateral or any other security for the Obligations, or to enforce a judgment or other court order in favor of Bank. Borrower expressly submits and consents in advance to such jurisdiction in any action or suit commenced in any such court, and Borrower hereby waives any objection that it may have based upon lack of personal jurisdiction, improper venue, or forum non conveniens and hereby consents to the granting of such legal or equitable relief as is deemed appropriate by such court. Borrower hereby waives personal service of the summons, complaints, and other process issued in such action or suit and agrees that service of such summons, complaints, and other process may be made by registered or certified mail addressed to Borrower at the address set forth in Section 10 of this Agreement and that service so made shall be deemed completed upon the earlier to occur of Borrower’s actual receipt thereof or three (3) days after deposit in the U.S. mails, proper postage prepaid.

TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, BORROWER AND BANK EACH WAIVE THEIR RIGHT TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION ARISING OUT OF OR BASED UPON THIS AGREEMENT, THE LOAN DOCUMENTS OR ANY CONTEMPLATED TRANSACTION, INCLUDING CONTRACT, TORT, BREACH OF DUTY AND ALL OTHER CLAIMS. THIS WAIVER IS A MATERIAL INDUCEMENT FOR BOTH PARTIES TO ENTER INTO THIS AGREEMENT. EACH PARTY HAS REVIEWED THIS WAIVER WITH ITS COUNSEL.

WITHOUT INTENDING IN ANY WAY TO LIMIT THE PARTIES’ AGREEMENT TO WAIVE THEIR RESPECTIVE RIGHT TO A TRIAL BY JURY, if the above waiver of the right to a trial by jury is not enforceable, the parties hereto agree that any and all disputes or controversies of any nature between them arising at any time shall be decided by a reference to a private judge, mutually selected by the parties (or, if they cannot agree, by the Presiding Judge of the Santa Clara County, California Superior Court) appointed in accordance with California Code of Civil Procedure Section 638 (or pursuant to comparable provisions of federal law if the dispute falls within the exclusive jurisdiction of the federal courts), sitting without a jury, in Santa Clara County, California; and the parties hereby submit to the jurisdiction of such court. The reference proceedings shall be conducted pursuant to and in accordance with the provisions of California Code of Civil Procedure §§ 638 through 645.1, inclusive. The private judge shall have the power, among others, to grant provisional relief, including without limitation, entering temporary restraining orders, issuing preliminary and permanent injunctions and appointing receivers. All such

-13-

proceedings shall be closed to the public and confidential and all records relating thereto shall be permanently sealed. If during the course of any dispute, a party desires to seek provisional relief, but a judge has not been appointed at that point pursuant to the judicial reference procedures, then such party may apply to the Santa Clara County, California Superior Court for such relief. The proceeding before the private judge shall be conducted in the same manner as it would be before a court under the rules of evidence applicable to judicial proceedings. The parties shall be entitled to discovery which shall be conducted in the same manner as it would be before a court under the rules of discovery applicable to judicial proceedings. The private judge shall oversee discovery and may enforce all discovery rules and order applicable to judicial proceedings in the same manner as a trial court judge. The parties agree that the selected or appointed private judge shall have the power to decide all issues in the action or proceeding, whether of fact or of law, and shall report a statement of decision thereon pursuant to the California Code of Civil Procedure § 644(a). Nothing in this paragraph shall limit the right of any party at any time to exercise self-help remedies, foreclose against collateral, or obtain provisional remedies. The private judge shall also determine all issues relating to the applicability, interpretation, and enforceability of this paragraph.

12.

GENERAL PROVISIONS

12.1 Successors and Assigns. This Agreement binds and is for the benefit of the successors and permitted assigns of each party.

12.2 Indemnification. Borrower agrees to indemnify, defend and hold Bank and its directors, officers, employees, agents, attorneys, or any other Person affiliated with or representing Bank harmless against: (a) all obligations, demands, claims, and liabilities (collectively, “Claims”) asserted by any other party in connection with the transactions contemplated by the Loan Documents; and (b) all losses or Bank Expenses incurred, or paid by Bank from, following, or arising from transactions between Bank and Borrower (including reasonable attorneys’ fees and expenses), except for Claims and/or losses directly caused by Bank’s gross negligence or willful misconduct.

12.6 Counterparts. This Agreement may be executed in any number of counterparts and by different parties on separate counterparts, each of which, when executed and delivered, are an original, and all taken together, constitute one Agreement. Delivery of an executed counterpart of a signature page of this Agreement by telecopy or electronic copy shall be effective as delivery of a manually executed counterpart of this Agreement.

12.7 Survival. All covenants, representations and warranties made in this Agreement continue in full force until this Agreement has terminated pursuant to its terms and all Obligations (other than inchoate indemnity obligations and any other obligations which, by their terms, are to survive the termination of this Agreement) have been satisfied. The obligation of Borrower in Section 12.2 to indemnify Bank, and the Bank’s obligations under Section 12.8 (Confidentiality), shall survive until the statute of limitations with respect to such claim or cause of action shall have run.

12.8 Confidentiality. In handling any confidential information, Bank and all employees and agents of Bank shall exercise the same degree of care that it exercises for its own proprietary information, but disclosure of information may be made: (a) to Bank’s Subsidiaries or Affiliates in connection with their present or prospective

-14-

business relations with Borrower (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such information and instructed to keep such information confidential in accordance with this Section 12.8); (b) to prospective transferees or purchasers of any interest in the Credit Extensions (provided that they have entered into a comparable confidentiality agreement in favor of Borrower to which Borrower is a party or pursuant to which Borrower and its Subsidiaries are third party beneficiaries); (c) as required by law, regulation, subpoena, or other order; (d) to Bank’s regulators or as otherwise required in connection with Bank’s examination or audit; and (e) as Bank considers appropriate in exercising remedies under this Agreement at any time during the existence of an Event of Default. Confidential information does not include information that either: (i) is in the public domain or in Bank’s possession when disclosed to Bank, or becomes part of the public domain after disclosure to Bank through no fault of Bank; or (ii) is disclosed to Bank by a third party on a non-confidential basis other than as a result of this Section 12.8, if Bank does not know that the third party is prohibited from disclosing the information. Should Bank be required to disclose any such information by virtue of a subpoena or similar process by any court, tribunal, or agency pursuant to items (c), (d) or (e) above, then Bank shall use commercially reasonable efforts to promptly notify Borrower thereof so as to allow Borrower, at its sole cost and expense, to seek a protective order or to take any other appropriate action to protect its rights.

12.9 Attorneys’ Fees, Costs and Expenses. In any action or proceeding between Borrower and Bank arising out of or relating to the Loan Documents, the prevailing party shall be entitled to recover its reasonable attorneys’ fees and other costs and expenses incurred, in addition to any other relief to which it may be entitled.

12.10 Additional Covenants of Bank in connection with Patriot Financing. In the event that Patriot obtains financing from one or more banks, financial institutions or other lending entities (collectively, the “Patriot Lenders”), then Bank agrees, if requested by the Patriot Lenders or any agent acting on their behalf: (a) to execute a control agreement or control agreements in form and substance reasonably satisfactory to Bank and the Patriot Lenders or such agent, with respect to each Patriot Account (if any) that Patriot elects to maintain with Bank following such financing; and (b) to execute such instruments and documents, and to authorize the filing of applicable amendments or partial release/termination statements with respect to financing statements filed by Bank against Borrower, as may be reasonably requested by the Patriot Lenders or any agent acting on their behalf to confirm that Bank security’s interest under the Loan Documents does not extend to the Excluded Patriot Equity Interest Collateral.
