Commitment Letter

Ladies and Gentlemen:

     Reference is made to the Credit Agreement dated as of August 2, 2004, as amended (the “Credit Agreement”), among Alion Science and Technology Corporation, a Delaware corporation (the “Borrower” or “you”), the lenders party thereto (the “Lenders”) and Credit Suisse (formerly known as Credit Suisse First Boston, “CS”), as Administrative Agent and Collateral Agent. Terms used but not defined in this commitment letter (including the Exhibits and other attachments hereto, this “Commitment Letter”) shall have the meanings assigned thereto in the Credit Agreement, in the Summary of Principal Terms and Conditions attached hereto as Exhibit A (the “Senior Facilities Term Sheet”) or in the Summary of Principal Terms and Conditions attached hereto as Exhibit B (the “Bridge Facility Term Sheet” and, together with the Senior Facilities Term Sheet, the “Term Sheets”).

     You have informed CS, in its capacity as the Administrative Agent, and Credit Suisse Securities (USA) LLC (“CS Securities” and, together with CS and their respective affiliates, “Credit Suisse”, “we” or “us”) that you intend (a) to acquire (the “Acquisition”) from Anteon Corporation (the “Seller”) all of the Seller’s rights, and to assume the Seller’s obligations, under the Anteon Contracts, (b) pursuant to Section 2.24 of the Credit Agreement, to obtain Incremental Term Loan Commitments for additional Term Loans (or, to the extent contemplated by the sixth paragraph of the fee letter dated the date hereof, among the Borrower, CS and CS Securities (the “Fee Letter”), Other Term Loans) in an aggregate principal amount of $50,000,000 (the “Incremental Term Facility”), (c) to borrow up to $175,000,000 of senior unsecured increasing

 2

rate loans (the “Bridge Loans”) under the senior unsecured credit facility (the “Bridge Facility”) described in the Bride Facility Term Sheet, and (d) to amend certain provisions of the Credit Agreement in order (i) to give effect to the making of loans under the Incremental Term Facility and the treatment of such loans as Term Loans for all purposes of the Credit Agreement and the other Loan Documents, (ii) to permit the Acquisition and the incurrence of the Bridge Loans and (iii) to make certain other changes thereto (the “Proposed Amendment”). If the Proposed Amendment is not obtained, then you would not obtain the Incremental Term Facility, but rather you would terminate the Credit Agreement, prepay all amounts outstanding thereunder and obtain the senior secured replacement credit facilities (the “Replacement Bank Facilities”) described in the Senior Facilities Term Sheet. The Incremental Term Facility, the Replacement Bank Facilities and the Bridge Facility are referred to collectively herein as the “Facilities”.

     In connection with the foregoing, (a) CS is pleased to advise you of its commitment to provide the entire principal amount of the Incremental Term Facility and the Bridge Facility and (b) CS Securities is pleased to advise you of its agreement to use commercially reasonable efforts to arrange the Proposed Amendment, in each case upon the terms and subject to the conditions set forth in this Commitment Letter. In addition, if the Proposed Amendment is not obtained, CS is pleased to advise you of its commitment to provide the entire principal amount of the Replacement Bank Facilities and the Bridge Facility, upon the terms and subject to the conditions set forth or referred to in this Commitment Letter.

     You hereby appoint (a) CS Securities to act, and CS Securities hereby agrees to act, as sole bookrunner and sole lead arranger in respect of the Facilities, and (b) CS to act, and CS hereby agrees to act, as sole administrative agent and sole collateral agent in respect of the Facilities. Each of CS Securities and CS, in such capacities, will perform the duties and exercise the authority customarily performed and exercised by it in such roles. You agree that no other titles will be awarded and no compensation (other than that expressly contemplated by this Commitment Letter and the Fee Letter) will be paid in connection with the Facilities or the Proposed Amendment unless you and we shall so agree.

     We reserve the right, prior to or after the execution of definitive documentation for the Facilities, to syndicate all or a portion of CS’s commitments in respect of the Facilities to a group of banks, financial institutions and other institutional lenders identified by us in consultation with and reasonably acceptable to you (together with CS, the “New Lenders”). We intend to commence syndication efforts promptly upon the execution of this Commitment Letter, and you agree actively to assist us in completing a satisfactory syndication. Such assistance shall include (a) your using commercially reasonable efforts to ensure that any syndication efforts benefit from your existing lending and investment banking relationships, (b) direct contact (at times mutually agreed) between senior management, representatives and advisors of the Borrower and the proposed New Lenders, (c) assistance by you in the preparation of a Confidential Information Memorandum for each of the Facilities and other marketing materials to be used in connection with the syndications, (d) prior to the launch of the syndications, the obtaining of ratings for the Incremental Term Facility or the Replacement Bank Facilities, as applicable, from each of Standard & Poor’s Ratings Service and Moody’s Investors Service, Inc., and (e) the hosting, with CS Securities, of one or more meetings (at times mutually agreed) of prospective New Lenders. You agree, at the request of CS Securities, to assist in the preparation of a version of the Confidential Information Memorandum and other marketing materials and presentations to be used in connection with the syndication of the Facilities, consisting exclusively of information and documentation that is either (i) publicly available or (ii) not material with respect to the

 3

Borrower and its subsidiaries or the Seller and its subsidiaries and any of their respective securities for purposes of United States Federal and state securities laws.

     CS Securities will manage, in consultation with you, all aspects of any syndication, including decisions as to the selection of institutions to be approached and when they will be approached, when their commitments will be accepted, which institutions will participate and the allocation of the commitments among the New Lenders (subject to the institutions which will participate and the commitment allocations being reasonably acceptable to you).

     To assist CS Securities in its syndication efforts, you agree promptly to prepare and provide to Credit Suisse all information with respect to the Borrower and its subsidiaries and the Acquisition, including all financial information and projections (the “Projections”), as we may reasonably request. You hereby represent and covenant that (a) all information other than the Projections and information of a general economic nature (the “Information”), taken as a whole, that has been or will be prepared by or on behalf of you or any of your representatives and that has been or will be made available to Credit Suisse by you or any of your representatives in connection with the transactions contemplated hereby is or will be, when furnished, complete and correct in all material respects and does not or will not, when furnished, contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements contained therein not materially misleading in light of the circumstances under which such statements are made and (b) the Projections that have been or will be prepared by or on behalf of you or any of your representatives and that have been or will be made available to Credit Suisse by you or any of your representatives in connection with the transactions contemplated hereby have been or will be prepared in good faith based upon assumptions that are reasonable at the time made and at the time the related Projections are made available to Credit Suisse (it being understood that the Projections are subject to significant uncertainties and contingencies, many of which are beyond the control of the Borrower, and that no assurance can be given that such Projections will be realized). You agree that if at any time prior to the closing of the Facilities and the effectiveness of the Proposed Amendment any of the representations in the preceding sentence would be incorrect if the Information and Projections were being furnished, and such representations were being made by you, at such time, then you will promptly supplement the Information and the Projections so that such representations will be correct under those circumstances. In arranging and syndicating the Facilities and arranging the Proposed Amendment, we will be entitled to use and rely primarily on the Information and the Projections without responsibility for independent verification thereof.

     As consideration for CS’s commitment hereunder, and Credit Suisse’s agreements to perform the services described herein, you agree to pay to CS Securities the fees set forth in the Fee Letter.

     CS’s commitment hereunder, and Credit Suisse’s agreements to perform the services described herein, are subject to (a) our not having discovered or otherwise become aware of any information not previously disclosed to us that we believe to be inconsistent in a material and adverse manner with our understanding, based on the information, taken as a whole, provided to us prior to the date hereof, of the business, assets, liabilities, operations, financial condition or Projections of the Borrower and its subsidiaries, taken as a whole, after giving effect to the Acquisition, (b) there not having occurred any event, change or condition since September 30, 2005 (the date of the most recent audited financial statements of the Borrower delivered to Credit Suisse as of the date hereof) that, individually or in the aggregate, has caused, or could reasonably

 4

be expected to cause, a material adverse condition in or materially adverse effect on the business, assets, liabilities, operations or financial condition of the Borrower and its subsidiaries, taken as a whole, (c) our satisfaction that, prior to and during the syndication of the Facilities, there shall be no other issues of debt securities or commercial bank or other credit facilities of the Borrower or its subsidiaries being offered, placed or arranged, (d) the negotiation, execution and delivery of definitive documentation with respect to the Facilities reflecting the terms and conditions set forth in this Commitment Letter and in the Credit Agreement and otherwise reasonably satisfactory to Credit Suisse and its counsel, (e) CS Securities having been afforded a period of at least 20 consecutive days following the launch of the general syndication of the Facilities (“launch” being defined as the date of the general meeting with prospective New Lenders) and immediately prior to the closing date to syndicate the Facilities, and (f) your compliance with the terms of the Fee Letter.

     You agree (a) to indemnify and hold harmless Credit Suisse and its officers, directors, employees, agents, controlling persons, members and successors and assigns (each, an “Indemnified Person”) from and against any and all losses, claims, damages, liabilities and expenses, joint or several, to which any such Indemnified Person may become subject arising out of or in connection with this Commitment Letter, the Fee Letter, the Transactions, the Facilities or any related transaction or any claim, litigation, investigation or proceeding relating to any of the foregoing, regardless of whether any such Indemnified Person is a party thereto, and to reimburse each such Indemnified Person upon demand for any reasonable legal or other reasonable expenses incurred in connection with investigating or defending any of the foregoing, provided that the foregoing indemnity will not, as to any Indemnified Person, apply to losses, claims, damages, liabilities or related expenses to the extent they are found in a final, non-appealable judgment of a court of competent jurisdiction to have resulted primarily from the willful misconduct or gross negligence of such Indemnified Person, and (b) to reimburse Credit Suisse, upon presentation of a summary statement, for all reasonable out-of-pocket expenses (including but not limited to expenses of Credit Suisse’s due diligence investigation, consultants’ fees (if such consultants are retained with your prior consent, which consent shall not be unreasonably withheld), syndication expenses, travel expenses and reasonable fees, disbursements and other charges of one counsel (as well as local counsel in each applicable jurisdiction), in each case incurred in connection with the Facilities and the preparation of this Commitment Letter, the Fee Letter, the definitive documentation for the Facilities and any security arrangements in connection therewith. Notwithstanding any other provision of this Commitment Letter, no Indemnified Person shall be liable for any damages arising from the unauthorized use by others of information or other materials obtained through electronic, telecommunications or other information transmission systems or for any indirect, special, punitive or consequential damages in connection with its activities related to the Facilities.

     You acknowledge that Credit Suisse may be providing debt financing, equity capital or other services (including financial advisory services) to other companies in respect of which you may have conflicting interests regarding the transactions described herein and otherwise. Neither we nor any of our affiliates will use confidential information obtained from you by virtue of the transactions contemplated by this Commitment Letter or our other relationships with you in connection with the performance by us of services for other companies, and we will not furnish any such information to other companies.

     This Commitment Letter shall not be assignable by you without the prior written consent of CS and CS Securities (and any attempted assignment without such consent shall be null and void), is intended to be solely for the benefit of the parties hereto (and Indemnitees (as defined below)), and is not intended to confer any benefits upon, or create any rights in favor of, any person other than the parties hereto (and Indemnitees). CS may assign its commitment hereunder to any of its affiliates or, with your consent (which shall not be unreasonably withheld or delayed), to any prospective New Lender. Any such assignment to an affiliate will not relieve CS from any of its obligations hereunder unless and until such affiliate shall have funded the portion of the commitment so assigned (or the commitment of CS hereunder shall have otherwise terminated in accordance with the terms of this Commitment Letter). Any such assignment to a prospective New Lender shall release CS from the portion of its commitment hereunder so assigned. Any and all obligations of, and services to be provided by, CS Securities or CS hereunder may be performed and any and all rights of CS Securities or CS hereunder may be exercised by or through any of their respective affiliates or branches.

     Each of the parties hereto hereby irrevocably and unconditionally (a) submits, for itself and its property, to the non-exclusive jurisdiction of any New York State court or Federal court of the United States of America sitting in New York City, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Commitment Letter or the

 6

transactions contemplated hereby, or for recognition or enforcement of any judgment, and agrees that all claims in respect of any such action or proceeding may be heard and determined in such New York State or, to the extent permitted by law, in such Federal court, (b) waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Commitment Letter or the transactions contemplated hereby in any New York State or in any such Federal court and (c) waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

For this purpose, the tax treatment of the transactions contemplated by this Commitment Letter and the Fee Letter is the purported or claimed U.S. federal income tax treatment of such transactions and the tax structure of such transactions is any fact that may be relevant to understanding the purported or claimed U.S. federal income tax treatment of such transactions.

     The compensation, reimbursement, indemnification, confidentiality, jurisdiction and waiver of jury trial provisions contained herein and in the Fee Letter shall remain in full force and effect regardless of whether definitive financing documentation for the Facilities or the Proposed Amendment shall be executed and delivered and notwithstanding the termination of this Commitment Letter.

Alion Science and Technology Corporation
$310,000,000 Senior Secured Replacement Bank Facilities
Summary of Principal Terms and Conditions

Borrower:		Alion Science and Technology Corporation, a Delaware corporation (the “Borrower”).
Transactions:		The Borrower intends to enter into a Purchase Agreement (the “Purchase Agreement”) with Anteon Corporation (the “Seller”), pursuant to which the Borrower will acquire (the “Acquisition”) all of the Seller’s rights, and assume the Seller’s obligations, under certain government contracts (the “Anteon Contracts”) in consideration of the payment by the Borrower to the Seller of approximately $225,000,000 in cash (the “Acquisition Consideration”). In connection with the foregoing, (a) the Borrower will obtain Senior Unsecured Term Loans in an aggregate amount of $175,000,000 (the “Senior Unsecured Term Loans”), (b) either (i) the Borrower’s existing Credit Agreement dated as of August 2, 2004, as amended (the “Existing Credit Agreement”) will be amended to, among other things, permit the Acquisition and the financing therefor and the Borrower will (x) obtain an Incremental Term Facility under the Existing Credit Agreement, as so amended, in the aggregate amount of $50,000,000, and (y) borrow $21,000,000 of delayed draw term loans (the “Delayed Draw Term Loans”) thereunder, or (ii) the Borrower will prepay in full, and terminate, the Existing Credit Agreement, using the proceeds of the Replacement Bank Facilities described below under the caption “Replacement Bank Facilities”, and (c) fees and expenses incurred in connection with the foregoing will be paid. The transactions described in this paragraph are collectively referred to herein as the “Transactions”.
Sources and Uses:		The approximate sources and uses of the funds necessary to consummate the Transactions are set forth on Exhibit C to the Commitment Letter (the “Commitment Letter”) to which this Term Sheet is attached.
Agent:		Credit Suisse, acting through one or more of its branches or affiliates (“CS”), will act as sole and exclusive administrative agent and collateral agent (collectively, the “Agent”) for a syndicate of banks, financial institutions and other institutional lenders

2

				(together with CS, the “Lenders”), and will perform the duties customarily associated with such roles.
Sole Bookrunner and Sole Lead Arranger:				Credit Suisse Securities (USA) LLC will act as sole bookrunner and sole lead arranger for the Senior Facilities described below (the “Arranger”), and will perform the duties customarily associated with such roles.
Syndication Agent:				At the option of the Arranger, a financial institution identified by the Arranger and acceptable to the Borrower (the “Syndication Agent”).
Documentation Agent:				At the option of the Arranger, a financial institution identified by the Arranger and acceptable to the Borrower (the “Documentation Agent”).
Replacement Bank Facilities:		(A)		A senior secured term loan facility in an aggregate principal amount of up to $260,000,000 (the “Term Facility”).
		(B)		A senior secured revolving credit facility in an aggregate principal amount of up to $50,000,000 (the “Revolving Facility” and, together with the Term Facility, the “Senior Facilities”), of which up to $5,000,000 will be available in the form of letters of credit.
				In connection with the Revolving Facility, CSFB (in such capacity, the “Swingline Lender”) will make available to the Borrower a swingline facility under which the Borrower may make short-term borrowings of up to $5,000,000. Except for purposes of calculating the Commitment Fee described below, any such swingline borrowings will reduce availability under the Revolving Facility on a dollar-for-dollar basis. Each Lender under the Revolving Facility shall, promptly upon request by the Swingline Lender, fund to the Swingline Lender its pro rata share of any swingline borrowings.
Purpose:		(A)		The proceeds of the Term Facility will be used by the Borrower on the date of the initial borrowing under the Senior Facilities (the “Closing Date”), solely (a) to refinance the Existing Credit Agreement and (b) together with the proceeds of the Senior Unsecured Term Loans, (i) to finance the Acquisition and (ii) to pay related fees and expenses.

3

		(B)		The proceeds of loans under the Revolving Facility will be used by the Borrower solely for working capital and other general corporate purposes, including for Permitted Acquisitions (as defined below).
		(C)		Letters of credit will be used solely to support payment obligations incurred in the ordinary course of business by the Borrower and its subsidiaries.
Availability:		(A)		The full amount of the Term Facility will be drawn in a single drawing on the Closing Date. Amounts borrowed under the Term Facility that are repaid or prepaid may not be reborrowed.
		(B)		No loans under the Revolving Facility may be made on the Closing Date. Thereafter, loans under the Revolving Facility will be available at any time prior to the final maturity of the Revolving Facility, in minimum principal amounts to be agreed upon. Amounts repaid under the Revolving Facility may be reborrowed.
Incremental Term Facility:				The definitive credit agreement for the Senior Facilities will provide for an uncommitted incremental term loan facility in an aggregate principal amount not to exceed $200,000,000.
Interest Rates and Fees:				As set forth on Annex I hereto.
Default Rate:				The applicable interest rate plus 2.0% per annum.
Letters of Credit:				Letters of credit under the Revolving Facility will be issued by CS or another Lender acceptable to the Borrower and the Agent (the “Issuing Bank”). Each letter of credit shall expire not later than the earlier of (a) 12 months after its date of issuance and (b) the fifth business day prior to the final maturity of the Revolving Facility; provided, however, that any letter of credit may provide for renewal thereof for additional periods of up to 12 months (which in no event shall extend beyond the date referred to in clause (b) above).
				Drawings under any letter of credit shall be reimbursed by the Borrower on the same business day. To the extent that the Borrower does not reimburse the Issuing Bank on the same business day, the Lenders under the Revolving Facility shall be irrevocably obligated to reimburse the Issuing Bank

4

				The issuance of all letters of credit shall be subject to the customary procedures of the Issuing Bank.
Final Maturity and Amortization:		(A)		Term Facility

				The Revolving Facility will mature on the date that is five years after the Closing Date.
Guarantees:				All obligations of the Borrower under the Facilities and under any interest rate protection or other hedging arrangements entered into with a Lender or any affiliate thereof (“Hedging Arrangements”) will be unconditionally guaranteed (the “Guarantees”) by each existing and subsequently acquired or organized domestic and, to the extent no adverse tax consequences to the Borrower would result therefrom, foreign subsidiary of the Borrower (the “Subsidiary Guarantors”).
Security:				The Facilities, the Guarantees and any Hedging Arrangements will be secured by substantially all the assets of the Borrower and each Subsidiary Guarantor (collectively, the “Collateral”), including but not limited to: (a) a perfected first-priority pledge of all the capital stock or other equity interests held by the Borrower or any Subsidiary Guarantor (which pledge, in the case of any foreign subsidiary, shall be limited to 100% of the non-voting stock or other equity interests (if any) and 65% of the voting stock or other equity interests of such foreign subsidiary to the extent the pledge of any greater percentage would result in adverse tax consequences to the Borrower) and (b) perfected first-priority security interests in, and mortgages on, substantially all tangible and intangible assets of the Borrower and each Subsidiary Guarantor (including but not limited to accounts receivable, inventory, equipment, general intangibles, investment property, intellectual property, real
