This LOAN AND SECURITY AGREEMENT dated as of the 15th day of July, 2005 (the “Effective Date”), between SILICON VALLEY BANK (“Bank”), whose address is 3003 Tasman Drive, Santa Clara, California 95054, and KOSAN BIOSCIENCES INCORPORATED, a Delaware corporation (“Borrower”), whose address is 3832 Bay Center Place, Hayward, CA 94545, provides the terms on which Bank will lend to Borrower and Borrower will repay Bank. The parties agree as follows:

1. ACCOUNTING AND OTHER TERMS.

Accounting terms not defined in this Agreement will be construed following GAAP. Calculations and determinations must be made following GAAP. The term “financial statements” includes the notes and schedules. The terms “including” and “includes” always mean “including (or includes) without limitation,” in this or any Loan Document.

2. LOAN AND TERMS OF PAYMENT.

2.1 Promise to Pay.

Borrower will pay Bank the unpaid principal amount of all Credit Extensions and interest on the unpaid principal amount of the Credit Extensions.

2.1.1 Term Loan.

(a) Bank will make a Term Loan available to Borrower. The Term Loan shall be available to Borrower in a maximum of two advances during the period from the Effective Date through May 31, 2006, and the minimum amount of the initial Term Loan advance shall be $15,000,000. To obtain an advance under the Term Loan, Borrower must notify Bank (the notice is irrevocable) by facsimile no later than 3:00 p.m. Pacific time one (1) Business Day before the day on which the Term Loan advance is to be made. The notice in the form of Exhibit B (Payment/Advance Form) must be signed by a Responsible Officer or designee.

(b) Interest accrued on the principal balance of the Term Loan shall be due and payable on the day of each month. With respect to each Term Loan advance, equal installments of principal and interest shall be due and payable on the day of each month commencing with the day of the 25th month following the date of such Term Loan advance, which installments shall be calculated based upon an 84-month amortization of the principal balance of such Term Loan advance outstanding on the day of such 25th month. If no Event of Default has occurred and is continuing, Bank may debit only Borrower’s deposit account (Account Number 3300091145) for principal and interest payments owing or any other amounts Borrower owes Bank. If an Event of Default has occurred and is continuing, Bank may debit any of Borrower’s deposit accounts, including Borrower’s deposit account (Account Number 3300091145) for principal and interest payments owing or any other amounts Borrower owes Bank. Bank will promptly notify Borrower when it debits Borrower’s accounts. These debits are not a set-off. Payments received after 12:00 noon 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 accrue.

(c) On the Maturity Date of each Term Loan advance, Borrower will pay to Bank the unpaid principal and accrued interest on such Term Loan advance and all other amounts due on such date with respect to such Term Loan advance, together with the Final Payment for such Term Loan advance.

(d) Borrower shall have the option to prepay all of either Term Loan advance without penalty or premium, provided Borrower (i) provides written notice to Bank of its election to make such prepayment at least ten (10) days prior to such prepayment, and (ii) pays, on the date of the prepayment (A) all unpaid scheduled payments then due (including principal and interest) with respect to such Term Loan advance; (B) the then principal balance of such Term Loan advance; (C) the Final Payment applicable to that Term Loan advance; and (D) all other amounts, if any, that shall then be due and payable hereunder with respect to this Agreement.

2.2 Intentionally Omitted.

2.3 Interest Rate.

(a) Interest Rate. The Term Loan accrues interest at a per annum fixed rate of interest equal to the greater of (i) four and four-tenths percent (4.4%), and (ii) one-half (0.5) percentage point above the Treasury Note Rate. The rate of interest applicable to the Term Loan shall be fixed on the date of the initial Term Loan advance. After an Event of Default and during the continuance thereof, Obligations accrue interest at three (3) percentage points above the rate effective immediately before the Event of Default. Interest is computed on a 360 day year for the actual number of days elapsed.

2.4 Fees.

Borrower will pay:

(a) Loan Fee. A loan fee equal to three-fourths of one percent (0.75%) of the difference between $35,000,000 and the aggregate amount advanced under the Term Loan as of the earlier of (i) May 31, 2006, or (ii) the date Borrower terminates this Agreement; provided that no such fee shall be payable in the event Bank does not fund the Term Loan after a request for a Term Loan advance by Borrower if no Event of Default then exists and if all conditions applicable hereunder to such advance have been satisfied by Borrower.

(b) Bank Expenses. All Bank Expenses (including reasonable attorneys’ fees and reasonable expenses) incurred through and after the date of this Agreement, are payable when due; provided that Bank Expenses reimbursable by Borrower consisting of reasonable attorneys’ fees and expenses incurred by Bank through the Effective Date shall not exceed $10,000 without Borrower’s prior written consent.

(c) Good Faith Deposit. Bank acknowledges receipt of Borrower’s good faith deposit in the amount of $50,000 (the “Deposit”). Bank will return the Deposit to Borrower on the Effective Date less such Bank Expenses as are then payable therefrom.

3. CONDITIONS OF LOANS

3.1 Conditions Precedent to Initial Credit Extension.

Bank’s obligation to make the initial Credit Extension is subject to the following conditions precedent:

(i) Borrower’s financial projections, approved by Borrower’s board of directors, in a format reasonably acceptable to Bank (and Bank hereby acknowledges that the format of Borrower’s projections delivered to Bank prior to the Effective Date is acceptable).

3.2 Conditions Precedent to all Credit Extensions.

Bank’s obligations to make each Credit Extension, including the initial Credit Extension, is subject to the following:

(a) timely receipt of any Payment/Advance Form; and

(b) the representations and warranties in Section 5 must be materially true on the date of the Payment/Advance Form and on the effective date of each Credit Extension and no Event of Default may 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 of Section 5 remain true in all material respects.

4. CREATION OF SECURITY INTEREST

4.1 Grant of Security Interest.

Borrower grants Bank a continuing security interest in all presently existing and later acquired Collateral to secure all Obligations and performance of each of Borrower’s duties under the Loan Documents. Except for Permitted Liens, any security interest will be a first priority security interest in the Collateral. Upon the occurrence and during the continuance of an Event of Default, Bank may place a “hold” on any deposit account pledged as Collateral. If this Agreement is terminated, Bank’s lien and security interest in the Collateral will continue until Borrower fully satisfies its Obligations. Upon the indefeasible payment in full in cash of all Obligations under this Agreement, Bank shall execute and deliver to Borrower all documents and instruments as shall be reasonably necessary to evidence termination of the security interest in the Collateral created hereunder, including a UCC-3 Termination Statement.

4.2 Authorization to File.

Borrower authorizes Bank to file financing statements without notice to Borrower, with all appropriate jurisdictions, as Bank deems appropriate, in order to perfect or protect Bank’s interest in the Collateral.

5. REPRESENTATIONS AND WARRANTIES

Borrower represents and warrants as follows:

5.1 Due Organization and Authorization.

Borrower and each Subsidiary is duly existing and in good standing in its state of formation and qualified and licensed to do business in, and in good standing in, any state in which the conduct of its business or its ownership of property requires that it be qualified, except where the failure to do so would not reasonably be expected to cause a Material Adverse Change. Borrower has not changed its state of formation or its organizational structure or type or any organizational number (if any) assigned by its jurisdiction of formation.

The execution, delivery and performance of the Loan Documents have been duly authorized, and do not conflict with Borrower’s formation 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 or by which it is bound in which the default would reasonably be expected to cause a Material Adverse Change.

5.2 Collateral.

Borrower has good title to the Collateral, free of Liens except Permitted Liens, or Borrower has Rights to each asset that is Collateral. Borrower has no other deposit account, other than the deposit accounts described in the Schedule. The Accounts are bona fide, existing obligations, and the service or property has been performed or delivered to the account debtor or its agent for immediate shipment to and unconditional acceptance by the account debtor. The Collateral is not in the possession of any third party bailee (such as at a warehouse) except as set forth on Schedule 6.7 (as the same may be amended pursuant to Section 6.7) and except for certain drug compounds of Borrower that are located with third party manufacturers. In the event that Borrower, after the date hereof, intends to store or otherwise deliver the Collateral to such a bailee (other than such manufacturers), then Borrower will receive the prior written consent of Bank, which consent shall not be unreasonably withheld, and such bailee must acknowledge in writing that the bailee is holding such Collateral for the benefit of Bank. All Inventory consisting of finished products is in all material respects of good and marketable quality, free from material defects.

5.3 Litigation.

Except as shown in the Schedule, there are no actions or proceedings pending or, to the knowledge of Borrower’s Responsible Officers, threatened by or against Borrower or any Subsidiary in which a likely adverse decision would reasonably be expected to cause a Material Adverse Change.

5.4 No Material Adverse Change in Financial Statements.

All consolidated financial statements for Borrower, and any Subsidiary, delivered to Bank fairly present in all material respects Borrower’s consolidated financial condition and Borrower’s consolidated results of operations. 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.

5.5 Solvency.

The fair salable value of Borrower’s assets exceeds the fair value of its liabilities; the 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.

5.6 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 has complied in all material respects with the Federal Fair Labor Standards Act. Borrower has not violated any laws, ordinances or rules, the violation of which would reasonably be expected to cause a Material Adverse Change. None of Borrower’s or any Subsidiary’s 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 Subsidiary has timely filed all required tax returns and paid, or made adequate provision to pay, all material taxes, except those being contested in good faith with adequate reserves under GAAP. Borrower and each Subsidiary has 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 the failure to do so could not reasonably be expected to cause a Material Adverse Change.

5.7 Subsidiaries.

Borrower does not own any stock, partnership interest or other equity securities except for Permitted Investments.

5.8 Full Disclosure.

No written representation, warranty or other statement of Borrower in any certificate or written statement given to Bank (taken together with all such written certificates and written statements 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 is recognized by Bank that the projections and forecasts provided by 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 and forecasted results.

6. AFFIRMATIVE COVENANTS

Borrower will do all of the following for so long as Bank has an obligation to lend under this Agreement, or there are outstanding Obligations:

6.1 Government Compliance.

Borrower will maintain its and all Subsidiaries’ legal existence and good standing in its jurisdiction of formation and maintain qualification in each jurisdiction in which the failure to so qualify would reasonably be expected to cause a material adverse effect on Borrower’s business or operations. Borrower will comply, and have each Subsidiary comply, with all laws, ordinances and regulations to which it is subject, noncompliance with which would reasonably be expected to cause a Material Adverse Change.

6.2 Financial Statements, Reports, Certificates.

(b) Within 30 days after the last day of each month, Borrower will deliver to Bank with the monthly financial statements a Compliance Certificate signed by a Responsible Officer in the form of Exhibit C.

(c) Bank has the right to audit Borrower’s Collateral at Borrower’s expense (not to exceed $5,000 unless an Event of Default has occurred and is continuing), but the audits will be conducted no more often than every year unless an Event of Default has occurred and is continuing. Each audit will be conducted during reasonable business hours and upon reasonable (and in no event less than 5 Business Days) prior notice, unless an Event of Default has occurred and is continuing.

Borrower will keep all Inventory consisting of finished products in good and marketable condition, free from material defects.

6.4 Taxes.

Borrower will make, and cause each Subsidiary to make, timely payment of all material federal, state, and local taxes or assessments (other than taxes and assessments which Borrower is contesting in good faith, with adequate reserves maintained in accordance with GAAP) and will deliver to Bank, on demand, appropriate certificates attesting to the payment.

6.5 Insurance.

Borrower will keep its business and the Collateral insured for risks and in amounts that are standard for Borrower’s industry. Insurance policies will be in a form, with companies, and in amounts that are standard for Borrower’s industry. All property policies will have a lender’s loss payable endorsement showing Bank as an additional loss payee and all general liability policies will show the Bank as an additional insured. At Bank’s request, Borrower will deliver certified copies of policies and evidence of all premium payments. If an Event of Default has occurred and is continuing, proceeds payable under any policy will, at Bank’s option, be payable to Bank on account of the Obligations. Bank hereby acknowledges that Borrower’s existing insurance policies (as disclosed to Bank prior to the Effective Date) satisfy the requirements of this Section 6.5.

At least six (6) months Remaining Months Liquidity. “Remaining Months Liquidity” is cash and cash equivalents, plus marketable securities, plus Eligible Accounts, divided by Cash Burn. “Cash Burn” is net loss, plus depreciation, plus amortization, minus any decrease in deferred revenue, plus any increase in deferred revenue, plus stock based compensation, in each case for the reporting period. Cash Burn shall be calculated on a rolling three-month basis. Eligible Accounts shall be included in foregoing calculation only after Bank shall have performed a collateral audit reasonably satisfactory to Bank.

likely to be cured within a reasonable time, then Borrower shall have an additional reasonable 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 have cured such default shall not be deemed an Event of Default (provided that no Credit Extensions will be made during such cure period).

9.1 Rights and Remedies.

When 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);

(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 considers advisable; notify any Person owing Borrower money of Bank’s security interest in the funds and verify the amount of the Account. Borrower must collect all payments in trust for Bank and, if requested by Bank, immediately deliver the payments to Bank in the form received from the account debtor, with proper endorsements for deposit;

(d) Make any payments and do any acts it considers necessary or reasonable to protect its security interest in the Collateral. Borrower will assemble the Collateral if Bank requires and make it available as Bank designates. 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 and pay all expenses incurred. Borrower grants Bank a license to enter and occupy any of its premises, without charge, to exercise any of Bank’s rights or remedies;

(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;

(f) Ship, reclaim, recover, store, finish, maintain, repair, prepare for sale, advertise for sale, and sell the Collateral; and

(g) Dispose of the Collateral according to the Code.

9.2 Power of Attorney.

Effective only when an Event of Default occurs and continues, Borrower irrevocably appoints Bank as its lawful attorney to: (i) endorse Borrower’s name on any checks or other forms of payment or security; (ii) sign Borrower’s name on any invoice or bill of lading for any Account or drafts against account debtors, (iii) make, settle, and adjust all claims under Borrower’s insurance policies; (iv) settle and adjust disputes and claims about the Accounts directly with account debtors, for amounts and on terms Bank determines reasonable; and (v) transfer the Collateral into the name of Bank or a third party as the Code permits. Bank may exercise the power of attorney to sign Borrower’s name on any documents necessary to perfect or continue the perfection of any security interest regardless of whether an Event of Default has occurred. Bank’s appointment as Borrower’s attorney in fact, and all of Bank’s rights and powers, coupled with an interest, are irrevocable until all Obligations have been fully repaid and performed and Bank’s obligation to provide Credit Extensions terminates.

9.3 Accounts Collection.

When an Event of Default occurs and continues, Bank may notify any Person owing Borrower money of Bank’s security interest in the funds and verify the amount of the Account. Borrower must collect all payments in trust for Bank and, if requested by Bank, immediately deliver the payments to Bank in the form received from the account debtor, with proper endorsements for deposit.

9.4 Bank Expenses.

If Borrower fails to pay any amount or furnish any required proof of payment to third persons, Bank may make all or part of the payment or obtain insurance policies required in Section 6.5, and take any action under the policies Bank deems prudent. Any amounts paid by Bank are Bank Expenses and immediately due and payable, bearing interest at the then applicable rate and 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 Bank’s Liability for Collateral.

If Bank complies with reasonable banking practices and Section 9-207 of the Code, it is not liable 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.

9.6 Remedies Cumulative.

Bank’s rights and remedies under this Agreement, the Loan Documents, and all other agreements 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 is not a waiver, election, or acquiescence. No waiver is effective unless signed by Bank and then is only effective for the specific instance and purpose for which it was given.

9.7 Demand Waiver.

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. NOTICES

All notices or demands by any party about this Agreement or any other related agreement must be in writing and be personally delivered or sent by an overnight delivery service, by certified mail, postage prepaid, return receipt requested, or by telefacsimile to the addresses set forth at the beginning of this Agreement. A party may change its notice address by giving the other party written notice.

11. CHOICE OF LAW, VENUE AND JURY TRIAL WAIVER

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.

BORROWER AND BANK EACH WAIVE THEIR RIGHT TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION ARISING OUT OF ANY OF 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.

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. Borrower may not assign this Agreement or any rights under it without Bank’s prior written consent which may be granted or withheld in Bank’s discretion. Bank has the right, without the consent of or notice to Borrower, to sell, transfer, negotiate, or grant participation in all or any part of, or any interest in, Bank’s obligations, rights and benefits under this Agreement.

12.2 Indemnification.

Borrower will indemnify, defend and hold harmless Bank and its officers, employees, and agents against: (a) all obligations, demands, claims, and liabilities asserted by any other party in connection with the transactions contemplated by the Loan Documents; and (b) all losses or Bank Expenses (subject to the limitation contained in Section 2.4(b)) incurred, or paid by Bank from, following, or consequential to transactions between Bank and Borrower (including reasonable attorneys fees and expenses), except as to (a) and (b) for losses caused by Bank’s gross negligence or willful misconduct.

12.3 Time of Essence.

Time is of the essence for the performance of all obligations in this Agreement.

12.4 Severability of Provision.

Each provision of this Agreement is severable from every other provision in determining the enforceability of any provision.

12.5 Amendments in Writing, Integration.

All amendments to this Agreement must be in writing and signed by Borrower and Bank. Except for that certain Mutual Non-Disclosure Agreement between Borrower and Bank dated as of May 4, 2005 (the “Non-Disclosure Agreement”), this Agreement represents the entire agreement about this subject matter, and supersedes prior negotiations or agreements. Except for the Non-Disclosure Agreement, all prior agreements, understandings, representations, warranties, and negotiations between the parties about the subject matter of this Agreement merge into this Agreement and the other Loan Documents.

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.

12.7 Survival.

All covenants, representations and warranties made in this Agreement continue in full force while any Obligations remain outstanding. The obligations of Borrower in Section 12.2 to indemnify Bank will survive until all statutes of limitations for actions that may be brought against Bank have run.

12.8 Confidentiality.

The terms of the Non-Disclosure Agreement shall apply with respect to information received by Bank in connection with this Agreement, except that the term of Bank’s obligations with respect to confidentiality and disclosure of such information shall continue until five years after the expiration or earlier termination of this Agreement and except that disclosure of information may be made (i) to Bank’s subsidiaries or affiliates in connection with their business with Borrower, (ii) to prospective transferees or purchasers of any interest in the loans (provided, however, Bank shall require that such prospective transferee or purchasers agree to abide by the terms of the Non-Disclosure Agreement), (iii) as required by law, regulation, subpoena, or other order, (iv) as required in connection with Bank’s examination or audit, and (v) as may be required in Bank’s exercise of remedies under this Agreement.
