     This LOAN AND SECURITY AGREEMENT dated March 20, 2002, between SILICON VALLEY BANK (“Bank”), whose address is ▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇ and ALEXZA MOLECULAR DELIVERY CORPORATION (“Borrower”), whose address is ▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇., ▇▇▇▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇ 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 promises to pay Bank the unpaid principal amount of all Credit Extensions and interest on the unpaid principal amount of the Credit Extensions.

2.1.1 Equipment Facility.

     (a) Subject to the terms and conditions of this Agreement, Bank agrees to lend to Borrower, from time to time prior to the Commitment Termination Date, equipment advances (each an “Equipment Advance” and collectively the “Equipment Advances”) in an aggregate amount not to exceed the Committed Equipment Line. When repaid, the Equipment Advances may not be re-borrowed. The proceeds of the Equipment Advances will be used solely to reimburse Borrower for the purchase of Eligible Equipment purchased within 90 days of the Equipment Advance, provided however, the proceeds of the initial Equipment Advance may be used to finance (i) Eligible Equipment purchased as far back as November 20, 2001 and (ii) Other Equipment up to $165,057 without invoices. Each Equipment Advance shall be considered a promissory note evidencing the amounts due hereunder for all purposes. Bank’s obligation to lend hereunder shall terminate on the earlier of (i) the occurrence and continuance of an Event of Default, or (ii) the Commitment Termination Date. For purposes of this Section, the minimum amount of each Equipment Advance is $100,000 (with the exception of the initial Equipment Advance and the final Equipment Advance which may be a lesser amount) and the maximum number of Equipment Advances that will be made is 6.

     (b) To obtain an Equipment Advance, Borrower will deliver to Bank a completed supplement in substantially the form attached as Exhibit C (“Loan Supplement”) signed by a Responsible Officer or his or her designee, copies of invoices for the Financed Equipment and such additional information as Bank may request at least five (5) Business Days before the proposed funding date (the “Funding Date”). On each Funding Date, Bank will specify in the Loan Supplement for each Equipment Advance, the Basic Rate, the Loan Factor, and the Payment Dates. If Borrower satisfies the conditions of each Equipment Advance specified herein, Bank will disburse such Equipment Advance by internal transfer to Borrower’s deposit account with Bank. Each Equipment Advance may not exceed 100% of the Original Stated Cost. Notwithstanding the foregoing, Equipment Advances used to reimburse Borrower for the purchase of Eligible Equipment made beyond 90 days of the Equipment Advance approved by Bank shall be advanced at 100% of the net book value in accordance with GAAP.

     (c) Bank’s obligation to lend the undisbursed portion of the Committed Equipment Line will terminate if, in Bank’s sole discretion, there has been a material adverse change in the general affairs, management, results of operation, condition (financial or otherwise) or the

prospects of Borrower, whether or not arising from transactions in the ordinary course of business, or there has been any material adverse deviation by Borrower, in excess of 25%, from Borrower’s most recent cash and operating forecast presented to and accepted by Bank prior to the execution of this Agreement.

2.2 Interest Rate, Payments.

     (a) Principal and Interest Payments On Payment Dates. Borrower will repay the Equipment Advances on the terms provided in the Loan Supplement. Borrower will make payments monthly in advance of principal and accrued interest for each Equipment Advance (collectively, “Scheduled Payments”), on the first Business Day of the month following the Funding Date (or commencing on the Funding Date if the Funding Date is the first Business Day of the month) with respect to such Equipment Advance and continuing thereafter during the Repayment Period on the first Business Day of each calendar month (each a “Payment Date”), in an amount equal to the Loan Factor multiplied by the Loan Amount for such Equipment Advance as of such Payment Date. All unpaid principal and accrued interest is due and payable in full on the last Payment Date with respect to such Equipment Advance. Payments received after 12:00 noon Pacific time are considered received at the opening of business on the next Business Day. An Equipment Advance may only be prepaid in accordance with Section 2.2(f).

     (b) Interest Rate. Borrower will pay interest on the Payment Dates (as described above) at the per annum rate of interest equal to the Basic Rate determined by Bank as of the Funding Date for each Equipment Advance in accordance with the definition of the Basic Rate. Any amounts outstanding during the continuance of an Event of Default shall bear interest at a per annum rate equal to the Basic Rate plus five percent (5%). If any change in the law increases Bank’s expenses or decreases its return from the Equipment Advances, Borrower will pay Bank upon request the amount of such increase or decrease.

     (c) Interim Payment. In addition to the Scheduled Payments, on the Funding Date for each Equipment Advance (unless the Funding Date is the first Business Day of the month) Borrower shall pay to Bank, on behalf of Bank, an amount (the “Interim Payment”) equal to (i) the initial Equipment Advance multiplied by (ii) the sum of the Prime Rate plus 1.5 percentage points, divided by (iii) 360 days and then multiplied by (iv) the number of days from the actual Funding Date of the Equipment Advance until the first day of the month following such Equipment Advance.

     (d) Final Payment. On the Maturity Date with respect to each Equipment Advance, Borrower will pay, in addition to the unpaid principal and accrued interest and all other amounts due on such date with respect to such Equipment Advance, an amount equal to the Final Payment.

     (e) Mandatory Prepayment Upon an Acceleration. If the Equipment Advances are accelerated following the occurrence of an Event of Default or otherwise, then Borrower will immediately pay to Bank (i) all unpaid Scheduled Payments (including principal and interest) with respect to each Equipment Advance, (ii) all remaining Scheduled Payments (including principal and interest unpaid) (iii) all accrued unpaid interest, including the default rate of interest, to the date of the prepayment, (iv) the Final Payment and (v) all other sums, if any, that shall have become due and payable with respect to any Equipment Advance.

     (f) Permitted Prepayment of Loans. Borrower shall have the option to prepay all, but not less than all, of the Equipment Advances advanced by Bank under this Agreement, provided Borrower (i) provides written notice to Bank of its election to prepay the Equipment Advances at least thirty (30) days prior to such prepayment, and (ii) pays, on the date of the prepayment (A) all accrued unpaid interest with respect to each Equipment Advance to the date of prepayment; (B) all outstanding principal with respect to each Equipment Advance (C) the Final Payment; and

(D) all other sums, if any, that shall have become due and payable hereunder with respect to this Agreement.

2.2.1 Request to Debit Accounts.

     Bank may debit any of Borrower’s deposit accounts including Account Number                                          for principal and interest payments or any amounts Borrower owes Bank when due. Bank will notify Borrower when it debits Borrower’s accounts. These debits are not a set-off.

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 could reasonably be expected to cause a Material Adverse Change.

5.2 Collateral.

All Inventory 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 and legal counsel, threatened by or against Borrower or any Subsidiary in which a likely adverse decision could reasonably be expected to cause a Material Adverse Change.

the transactions in this Agreement; and Borrower is able to pay its debts (including trade debts) as they mature.

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 ▇▇▇▇ 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 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.

9.4 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. Except as provided above, Borrower bears all risk of loss, damage or destruction of the Collateral.

9.5 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.

9.6 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.

The following Sections are hereby incorporated into the Loan Agreement:

2.1.2 Equipment 2 Facility.

(a) Subject to the terms and conditions of this Agreement, Bank agrees to lend to Borrower, from time to time prior to the Commitment 2 Termination Date, equipment advances (each an “Equipment 2 Advance” and collectively the “Equipment 2 Advances”) in an aggregate amount not to exceed the Committed Equipment 2 Line. When repaid, the Equipment 2 Advances may not be re-borrowed. The proceeds of the Equipment 2 Advances will be used solely to reimburse Borrower for the purchase of Eligible Equipment purchased within 90 days of the Equipment 2 Advance. Each Equipment 2 Advance shall be considered a promissory note evidencing the amounts due hereunder for all purposes. Bank’s obligation to lend hereunder shall terminate on the earlier of (i) the occurrence and continuance of an Event of Default, or (ii) the Commitment 2 Termination Date. For purposes of this Section, the minimum amount of each Equipment 2 Advance is $100,000 (with the exception of the final Equipment 2 Advance which may be a lesser amount) and the maximum number of Equipment 2 Advances that will be made is 8.

(b) To obtain an Equipment 2 Advance, Borrower will deliver to Bank a completed supplement in substantially the form attached as Exhibit D (“Loan 2 Supplement”) signed by a Responsible Officer or his or her designee, copies of invoices for the Financed Equipment and such additional information as Bank may request at least five (5) Business Days before the proposed funding date (the “Funding Date”). On each Funding Date, Bank will specify in the Loan 2 Supplement for each Equipment 2 Advance, the Basic Rate, the Loan Factor, and the Payment Dates. If Borrower satisfies the conditions of each Equipment 2 Advance specified herein, Bank will disburse such Equipment 2 Advance by

internal transfer to Borrower’s deposit account with Bank. Each Equipment 2 Advance may not exceed 100% of the Original Stated Cost. Notwithstanding the foregoing, Equipment 2 Advances used to reimburse Borrower for the purchase of Eligible Equipment made beyond 90 days of the Equipment Advance approved by Bank on a case by case basis shall be advanced at 100% of the net book value in accordance with GAAP.

(c) Bank’s obligation to lend the undisbursed portion of the Committed Equipment 2 Line will terminate if, in Bank’s sole discretion, there has been a material adverse change in the general affairs, management, results of operation, condition (financial or otherwise) or the prospects of Borrower, whether or not arising from transactions in the ordinary course of business, or there has been any material adverse deviation by Borrower, in excess of 25%, from Borrower’s most recent cash and operating forecast presented to and accepted by Bank prior to the execution of this Agreement.

All unpaid principal and accrued interest is due and payable in full on the last Payment Date with respect to such Equipment 2 Advance.

Any amounts outstanding during the continuance of an Event of Default shall bear interest at a per annum rate equal to the greater of either (i) Basic Rate plus five percentage points or (ii) 10.75% per annum. If any change in the law increases Bank’s expenses or decreases its return from the Equipment 2 Advances, Borrower will pay Bank upon request the amount of such increase or decrease.

(c) Interim Payment. In addition to the Scheduled Payments, on the Funding Date for each Equipment 2 Advance (unless the Funding Date is the first Business Day of the month) Borrower shall pay to Bank, on behalf of Bank, an amount (the “Interim Payment”) equal to (i) the initial Equipment 2 Advance multiplied by (ii) the Basic Rate, divided by (iii) 360 days and then multiplied by (iv) the number of days from the actual Funding Date of the Equipment 2 Advance until the first day of the month following such Equipment 2 Advance.
