LOAN AGREEMENT

THIS LOAN AGREEMENT (the “Agreement”), dated as of February 11, 2005, is between SPACEHAB, INCORPORATED, a Washington corporation (the “Borrower”), and FIRST AMERICAN BANK, SSB, a statement savings bank organized under the laws of the State of Texas (the “Lender”).

R E C I T A L S:

The Borrower has requested the Lender to extend credit to the Borrower in the form described in this Agreement the Lender is willing to make such extensions of credit to the Borrower upon the terms and conditions hereinafter set forth.

NOW THEREFORE, in consideration of the premises and the mutual covenants herein contained, the parties hereto agree as follows:

Definitions

1.1 Definitions. As used in this Agreement, the capitalized terms shall have the meanings given such terms in Annex I (and as defined in any other Annex) to this Agreement, except as may be defined above. In the event of any conflict between a particular definition in Annex I and any other Annex, the definitions set forth in Annex I shall control unless the definition outside Annex I specifically states that it is intended to control over the equivalent Annex I definition. Any Annex page containing the words “NOT APPLICABLE” shall constitute the agreement of the Lender and the Borrower that the subject matter of such Annex is inapplicable and of no effect with respect to this Agreement.

Advances

2.1 Advances. Subject to the terms and conditions of this Agreement, the Lender agrees to make one or more revolving credit Advances to the Borrower from time to time from the date hereof to and including the Termination Date in an aggregate principal amount at any time outstanding up to but not exceeding the amount of the Commitment, provided that the aggregate amount of all revolving credit Advances at any time outstanding shall not exceed the lesser of (a) the amount of the Commitment or (b) the Borrowing Base. Subject to the foregoing limitations, and the other terms and provisions of this Agreement, the Borrower may borrow, repay, and reborrow hereunder. The Lender shall be under no obligation to make an Advance hereunder any time Default exists.

2.2 The Revolving Credit Note. The obligation of the Borrower to repay the revolving credit Advances and interest thereon shall be evidenced by the Revolving Credit Note executed by the Borrower, payable to the order of the Lender, in the principal amount of the Commitment as originally in effect, and dated the date hereof.

2.3 Repayment of Advances. The Borrower shall repay the unpaid principal amount of all revolving credit Advances on the Termination Date.

2.4 Interest. The unpaid principal amount of the revolving credit Advances shall bear interest prior to maturity at a varying rate per annum equal from day to day to the lesser of (a) the Maximum Rate, or (b) the Applicable Rate. If at any time the rate of interest specified in clause (b) above shall exceed the Maximum Rate, thereby causing the interest accruing on the Advances to be limited to the Maximum Rate, then any subsequent reduction in the Applicable Rate shall not reduce the rate of interest on the Advances below the Maximum Rate until the aggregate amount of interest accrued on the revolving credit Advances equals the aggregate amount of interest which would have accrued on the revolving credit Advances if the interest rate specified in clause (b) above had at all times been in effect. Accrued and unpaid interest on the revolving credit Advances shall be payable on each Payment Date and on the Termination Date. Notwithstanding the foregoing, any outstanding principal of any Advance and (to the fullest extent permitted by law) any other amount payable by the Borrower under this Agreement or any other Loan Document that is not paid in full when due (whether at stated maturity, by acceleration, or otherwise) shall bear interest at the Default Rate for the period from and including the due date thereof to but excluding the date the same is paid in full. Additionally, upon the occurrence of an Event of Default (and from the date of such occurrence) all outstanding and unpaid principal amounts of all of the Obligations shall, to the extent permitted by law, bear interest at the Default Rate until such time as the Lender shall waive in writing the application of the Default Rate to such Event of Default situation. Interest payable at the Default Rate shall be payable from time to time on demand.

2.5 Borrowing Procedure. The Borrower shall give the Lender notice of each such Advance by means of an Advance Request Form containing the information required therein and delivered (by hand or by mechanically confirmed facsimile) to the Lender no later than 1:00 p.m. (Texas time) on the day on which the Advance is desired to be funded. The Lender at its option may accept telephonic requests for Advances, provided that such acceptance shall not constitute a waiver of the Lender’s right to require delivery of an Advance Request Form in connection with subsequent revolving credit Advances. Any telephonic request for a revolving credit Advance by the Borrower shall be promptly confirmed by submission of a properly completed Advance Request Form to the Lender. Subject to the terms and conditions of this Agreement, each Advance shall be made available to the Borrower by depositing the same, in immediately available funds, in an account of the Borrower maintained with the Lender at the Principal Office designated by the Borrower.

2.6 Use of Proceeds. The proceeds of revolving credit Advances shall be used by the Borrower for working capital and/or capital expenditures incurred in the ordinary course of business.

2.7 Unused Facility Fee. The Borrower agrees to pay to the Lender an unused facility fee on the daily average unused amount of the Commitment for the period from and including the date of this Agreement to and including the Termination Date, at the rate of one half of one percent (.50%) per annum based on a 360-day year and the actual number of days elapsed. For the purpose of calculating the commitment fee hereunder, the Commitment shall be deemed utilized by the amount of all outstanding revolving credit Advances. Accrued commitment fees

shall be payable in arrears on each consecutive Quarterly Payment Date and on the Termination Date. In the event that the Borrower maintains, on average, collected balances of $5,000,000 or more for each period the unused commitment fee is charged, the fee shall be reduced from one half of one percent (.50%) per annum to one quarter of one percent (.25%) per annum. The Borrower acknowledges that it is not required to maintain any deposits as compensating balances with the Lender or as a condition precedent to the credit being made available hereunder.

III

Payments

3.1 Method of Payment. All payments of principal, interest, and other amounts to be made by the Borrower under this Agreement and the other Loan Documents shall be made to the Lender at the Principal Office in Dollars and immediately available funds, without setoff, deduction, or counterclaim, not later than 11:00 A.M., Texas time, on the date on which such payment shall become due (each such payment made after such time on such due date to be deemed to have been made on the next succeeding Business Day). The Borrower shall, at the time of making each such payment, specify to the Lender the sums payable by the Borrower under this Agreement and the other Loan Documents to which such payment is to be applied (and in the event the Borrower fails to so specify, or if an Event of Default has occurred and is continuing, the Lender may apply such payment to the Obligations in the order set forth in Section 3.2 of the Revolving Credit Note or in such order and manner as it may elect in its sole discretion). Whenever any payment under this Agreement or any other Loan Document shall be stated to be due on a day that is not a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of the payment of interest and commitment fee, as the case may be.

3.2 Voluntary Prepayment. The Borrower may prepay the Advances in whole at any time or from time to time in part without premium or penalty but with accrued interest to the date of prepayment on the amount so prepaid, provided that each partial prepayment shall be in the principal amount of $10,000.00 or an integral multiple thereof.

3.3 Mandatory Prepayment. If at any time the outstanding principal amount of the Advances exceeds the Borrowing Base, the Borrower shall, within five (5) days, prepay the outstanding Advances by the amount of the excess.

3.4 Computation of Interest. Interest on the Advances and all other amounts payable by the Borrower hereunder shall be computed on the basis of a year of 360 days and the actual number of days elapsed (including the first day but excluding the last day) unless such calculation would result in a usurious rate, in which case interest shall be calculated on the basis of a year of 365 or 366 days, as the case may be.

3.5 Capital Adequacy. If after the date hereof, the Lender shall have determined that the adoption or implementation of any applicable law, rule, or regulation regarding capital adequacy (including, without limitation, any law, rule, or regulation implementing the Basle Accord), or any change therein, or any change in the interpretation or administration thereof by any central bank or other Governmental Authority charged with the interpretation or

administration thereof, or compliance by the Lender (or its parent) with any guideline, request, or directive regarding capital adequacy (whether or not having the force of law) of any such central bank or other Governmental Authority (including, without limitation, any guideline or other requirement implementing the Basle Accord), has or would have the effect of reducing the rate of return on the Lender’s (or its parent’s) capital as a consequence of its obligations hereunder or the transactions contemplated hereby to a level below that which the Lender (or its parent) could have achieved but for such adoption, implementation, change, or compliance (taking into consideration the Lender’s policies with respect to capital adequacy) by an amount deemed by the Lender to be material, then from time to time, within ten (10) Business Days after demand by the Lender, the Borrower shall pay to the Lender (or its parent) such additional amount or amounts as will compensate the Lender for such reduction. A certificate of the Lender claiming compensation under this Section and setting forth the additional amount or amounts to be paid to it hereunder shall be conclusive, provided that the determination thereof is made on a reasonable basis. In determining such amount or amounts, the Lender may use any reasonable averaging and attribution methods.

Security

4.1 Collateral. To secure full and complete payment and performance of the Obligations, the Borrower shall execute and deliver or cause to be executed and delivered the documents described below covering the property and collateral described in this Section 4.1 (which, together with any other property and collateral which may now or hereafter secure the Obligations or any part thereof, is sometimes herein called the “Collateral”):

4.2 Setoff. If an Event of Default shall have occurred and be continuing, the Lender shall have the right to set off and apply against the Obligations in such manner as the Lender may determine, at any time and without notice to the Borrower, any and all deposits (general or special, time or demand, provisional or final) or other sums at any time credited by or owing from the Lender to the Borrower whether or not the Obligations are then due. As further security for the Obligations, the Borrower hereby grants to the Lender a security interest in all money, instruments, and other property of the Borrower now or hereafter held by the Lender, including, without limitation, property held in safekeeping. In addition to the Lender’s right of setoff and as

The Borrower hereby waives, releases, and agrees not to ▇▇▇ the Lender or any of the Lender’s Affiliates, officers, directors, employees, attorneys, or agents for punitive damages in respect of any claim in connection with, arising out of, or in any way related to, this Agreement or any of the other Loan Documents, or any of the transactions contemplated by this Agreement or any of the other Loan Documents.

11.4 No Duty. All attorneys, accountants, appraisers, and other professional Persons and consultants retained by the Lender shall have the right to act exclusively in the interest of the Lender and shall have no duty of disclosure, duty of loyalty, duty of care, or other duty or obligation of any type or nature whatsoever to the Borrower or any of the Borrower’s shareholders or any other Person.

11.5 Lender Not Fiduciary. The relationship between the Borrower and the Lender is solely that of debtor and creditor, and the Lender has no fiduciary or other special relationship with the Borrower, and no term or condition of any of the Loan Documents shall be construed so as to deem the relationship between the Borrower and the Lender to be other than that of debtor and creditor.

11.6 Equitable Relief. The Borrower recognizes that in the event the Borrower fails to pay, perform, observe, or discharge any or all of the Obligations, any remedy at law may prove to be inadequate relief to the Lender. The Borrower therefore agrees that the Lender, if the Lender so requests, shall be entitled to temporary and permanent injunctive relief in any such case without the necessity of proving actual damages.

11.7 No Waiver; Cumulative Remedies. No failure on the part of the Lender to exercise and no delay in exercising, and no course of dealing with respect to, any right, power, or privilege under this Agreement shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power, or privilege under this Agreement preclude any other or further exercise thereof or the exercise of any other right, power, or privilege. The rights and remedies provided for in this Agreement and the other Loan Documents are cumulative and not exclusive of any rights and remedies provided by law.

This Agreement is binding upon and shall inure to the benefit of the Lender and the Borrower and their respective successors and assigns, except that the Borrower may not assign or transfer any of its rights or obligations under this Agreement without the prior written consent of the Lender.

11.9 Survival. All representations and warranties made in this Agreement or any other Loan Document or in any document, statement, or certificate furnished in connection with this Agreement shall survive the execution and delivery of this Agreement and the other Loan Documents and repayment of the Obligation, and no investigation by the Lender or any closing shall affect the representations and warranties or the right of the Lender to rely upon them.

11.10 ENTIRE AGREEMENT; AMENDMENT; WAIVERS. THIS AGREEMENT, THE NOTE, AND THE OTHER LOAN DOCUMENTS REFERRED TO HEREIN EMBODY THE FINAL, ENTIRE AGREEMENT AMONG THE PARTIES HERETO AND SUPERSEDE ANY AND ALL PRIOR COMMITMENTS, AGREEMENTS, REPRESENTATIONS, AND UNDERSTANDINGS, WHETHER WRITTEN OR ORAL, RELATING TO THE SUBJECT MATTER HEREOF AND MAY NOT BE CONTRADICTED OR VARIED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OR DISCUSSIONS OF THE PARTIES HERETO. THERE ARE NO ORAL AGREEMENTS AMONG THE PARTIES HERETO. The provisions of this Agreement and the other Loan Documents to which the Borrower is a party may be amended or waived only by an instrument in writing signed by the parties hereto.

11.11 Maximum Interest Rate. No provision of this Agreement or any other Loan Document shall require the payment or the collection of interest in excess of the maximum amount permitted by applicable law. If any excess of interest in such respect is hereby provided for, or shall be adjudicated to be so provided, in any Loan Document or otherwise in connection with this loan transaction, the provisions of this Section shall govern and prevail and neither the Borrower nor the sureties, guarantors, successors, or assigns of the Borrower shall be obligated to pay the excess amount of such interest or any other excess sum paid for the use, forbearance, or detention of sums loaned pursuant hereto. In the event the Lender ever receives, collects, or applies as interest any such sum, such amount which would be in excess of the maximum amount permitted by applicable law shall be applied as a payment and reduction of the principal of the indebtedness evidenced by the Note; and, if the principal of the Note has been paid in full, any remaining excess shall forthwith be paid to the Borrower. In determining whether or not the interest paid or payable exceeds the Maximum Rate, the Borrower and the Lender shall, to the extent permitted by applicable law, (a) characterize any non-principal payment as an expense, fee, or premium rather than as interest, (b) exclude voluntary prepayments and the effects

thereof, and (c) amortize, prorate, allocate, and spread in equal or unequal parts the total amount of interest throughout the entire contemplated term of the indebtedness evidenced by the Note so that interest for the entire term does not exceed the Maximum Rate.

11.12 Notices. All notices and other communications provided for in this Agreement and the other Loan Documents to which the Borrower is a party shall be given in writing and made by telecopy or mailed by certified mail return receipt requested, or delivered to the intended recipient at the “Address for Notices” specified below its name on the signature pages hereof; or, as to any party at such other address as shall be designated by such party in a notice to the other party given in accordance with this Section. Except as otherwise provided in this Agreement, all such communications shall be deemed to have been duly given when transmitted by telecopy, subject to mechanical confirmation of receipt, or when personally delivered or, in the case of a mailed notice, when duly deposited in the mails, in each case given or addressed as aforesaid.

11.13 Governing Law; Venue; Service of Process.

EXISTING LITIGATION

Contract Claim. In January 2004, Borrower filed a formal proceeding with NASA seeking indemnification under Borrower’s ReALMS contract in the amount of $87.7 million for the value of Borrower’s RDM and related equipment that was destroyed during the STS-107 Space Shuttle Columbia tragedy. NASA responded to this contract claim on October 5, 2004. NASA’s determination states that its liability is limited under the ReALMS contract to $8.0 million. Borrower received payment of $8.2 million, which included $0.2 million of interest, from NASA in October 2004. In January 2005, Borrower filed an appeal of NASA’s decision to deny its claim for indemnification in excess of $8.0 million with the Armed Services Board of Contract Appeals.

Lloyd’s Complaint. In January 2004, Lloyd’s, Borrower’s insurer for the RDM, filed a complaint in the United States District Court for the Western District of Washington seeking the return of the $17.7 million Lloyd’s had paid to Borrower under the RDM insurance policy alleging that, among other things, (i) such proceeds were paid erroneously primarily due to the fact that NASA had not paid indemnification due to Borrower prior to the payment of the insurance proceeds, (ii) Borrower and its insurance broker misled Lloyd’s in issuing the policy, and (iii) Borrower has not cooperated with Lloyd’s in protecting Lloyd’s right of subrogation. In February 2004, Lloyd’s withdrew its complaint from the United States District Court and filed a similar complaint in Superior Court of the State of Washington. Borrower believes that Lloyd’s complaint is without merit and will continue to respond to the complaint accordingly.

Tort Claim. On November 8, 2004, Borrower filed a second claim with NASA seeking damages of $79.7 million under the Federal Tort Claims Act for the loss of the RDM resulting from NASA’s alleged negligence leading to the destruction of the Space Shuttle Columbia and the loss of the RDM. Borrower’s claim represents its loss of $87.7 million less the $8.0 million recovered from NASA. Under federal tort claim procedures, NASA has statutory deadlines for responding to such claims. In the event that Borrower’s administrative claim is denied, Borrower would have the right to pursue the claim in Federal District Court.

(b) If on either the date of determination or the date any Advance is to be made hereunder the Consolidated Tangible Net Worth shall be less than the Required Amount, then: (i) the Borrower shall, pursuant to documentation in form and substance reasonably satisfactory to the Lender, within three (3) business days pledge to the Lender cash or deposit accounts (the “Cash Collateral”) in an amount equal to the lesser of (A) the revolving credit Advances at such time outstanding and (B) the difference, as most recently calculated, between Consolidated Tangible Net Worth and the Required Amount; and (ii) the Lender shall not be required to make additional revolving credit Advances to the Borrower unless after giving effect to such additional Advances the Borrower shall be in compliance with the requirements of clause (b)(i) above.
