The undersigned hereby tenders to Red Hawk Enterprises Corp., a Nevada corporation (“Purchaser”), which is a wholly owned subsidiary of General Dynamics Corporation, a Delaware corporation (“Parent”), the above-described shares of common stock, par value $0.001 per share (the “Shares”), of CSRA Inc., a Nevada corporation (the “Company”), pursuant to Purchaser’s offer to purchase all outstanding Shares at $40.75 per Share in cash, without interest thereon and less any applicable withholding of taxes, upon the terms and subject to the conditions set forth in the Offer to Purchase dated March 5, 2018 (as amended or supplemented from time to time, the “Offer to Purchase”), receipt of which is hereby acknowledged, and in this Letter of Transmittal (which, together with any amendments or supplements thereto, collectively constitute the “Offer”). The Offer expires at 11:59 PM, New York City time, on April 2, 2018, unless extended as described in the Offer to Purchase (as extended, the “Expiration Date”). Purchaser reserves the right to transfer or assign, in whole or from time to time in part, to one or more wholly owned subsidiaries of Parent the right to purchase Shares tendered pursuant to the Offer, but any such transfer or assignment will not relieve Purchaser of its obligations under the Offer or prejudice your rights to receive payment for Shares validly tendered and accepted for payment.

Upon the terms and subject to the conditions of the Offer (including, if the Offer is extended or amended, the terms and conditions of any such extension or amendment) and subject to, and effective upon, acceptance for payment of and payment for the Shares validly tendered herewith and not properly withdrawn prior to the Expiration Date in accordance with the terms of the Offer, the undersigned hereby sells, assigns and transfers to, or upon the order of, Purchaser all right, title and interest in and to all the Shares that are being tendered hereby (and any and all dividends, distributions, rights, other Shares or other securities issued or issuable in respect thereof on or after the date hereof (collectively, but excluding any dividends authorized and declared prior to the “Effective Time” as defined in the Merger Agreement, “Distributions”)) and irrevocably constitutes and appoints the Purchaser the true and lawful agent and attorney-in-fact of the undersigned with respect to such Shares (and any and all Distributions), with full power of substitution (such power of attorney being deemed to be an irrevocable power coupled with an interest), to (i) deliver certificates for such Shares (and any and all Distributions), or transfer ownership of such Shares (and any and all Distributions) on the account books maintained by the Book-Entry Transfer Facility, together, in any such case, with all accompanying evidences of transfer and authenticity, to or upon the order of Purchaser, (ii) present such Shares (and any and all Distributions) for transfer on the books of the Company and (iii) receive all benefits and otherwise exercise all rights of beneficial ownership of such Shares (and any and all Distributions), all in accordance with the terms and subject to the conditions of the Offer.

By executing this Letter of Transmittal, the undersigned hereby irrevocably appoints each of Kimberly A. Kuryea, Jason W. Aiken and Gregory S. Gallopoulos, individually, in their respective capacities as officers of Purchaser, the attorneys-in-fact and proxies of the undersigned, each with full power of substitution, (i) to vote at any annual or special meeting of the Company’s stockholders or any adjournment or postponement thereof or otherwise in such manner as each such attorney-in-fact and proxy or its, his or her substitute shall in its, his or her sole discretion deem proper with respect to, (ii) to execute any written consent concerning any matter as each such attorney-in-fact and proxy or its, his or her substitute shall in its, his or her sole discretion deem proper with respect to and (iii) to otherwise act as each such attorney-in-fact and proxy or its, his or her substitute shall in its, his or her sole discretion deem proper with respect to, in each case, all of the Shares (and any and all Distributions) tendered hereby and accepted for payment by Purchaser. This appointment will be effective if and when, and only to the extent that, Purchaser accepts such Shares for payment pursuant to the Offer. This power of attorney and proxy are irrevocable and are granted in consideration of the acceptance for payment of such Shares in accordance with the terms of the Offer. Such acceptance for payment shall, without further action, revoke any prior powers of attorney and proxies granted by the undersigned at any time with respect to such Shares (and any and all Distributions), and no subsequent powers of attorney, proxies, consents or revocations may be given by the undersigned with respect thereto (and, if given, will not be deemed effective). Purchaser reserves the right to require that, in order for the Shares to be deemed validly tendered, immediately upon

4

Purchaser’s acceptance for payment of such Shares, Purchaser must be able to exercise full voting, consent and other rights with respect to such Shares (and any and all Distributions), including voting at any meeting of the Company’s stockholders.

The undersigned hereby represents and warrants that the undersigned has full power and authority to tender, sell, assign and transfer the Shares tendered herein (and any and all Distributions) and that when the same are accepted for payment by Purchaser, Purchaser will acquire good, marketable and unencumbered title to such Shares (and any and all Distributions), free and clear of all liens, restrictions, charges and encumbrances and the same will not subject to any adverse claims. The undersigned will, upon request, execute and deliver any additional documents deemed by the Depositary or Purchaser to be necessary or desirable to complete the sale, assignment and transfer of the Shares tendered hereby. In addition, the undersigned will promptly remit and transfer to the Depositary for the account of Purchaser all Distributions in respect of any and all Shares tendered hereby, accompanied by appropriate documentation of transfer, and, pending such remittance and transfer or appropriate assurance thereof, Purchaser shall be entitled to all rights and privileges as owner of each such Distribution and may deduct from the purchase price of Shares tendered hereby the amount or value of such Distributions as determined by Purchaser in its sole discretion.

All authority herein conferred or agreed to be conferred shall not be affected by, and shall survive, the death or incapacity of the undersigned, and any obligation of the undersigned hereunder shall be binding upon the heirs, executors, administrators, personal representatives, trustees in bankruptcy, successors and assigns of the undersigned. Except as stated in Section 4 of the Offer to Purchase, this tender is irrevocable.

The undersigned understands that Purchaser’s acceptance for payment of Shares tendered pursuant to the Offer will constitute a binding agreement between the undersigned and Purchaser upon the terms and subject to the conditions of the Offer (including, if the Offer is extended or amended, the terms and conditions of any such extension or amendment).

Unless otherwise indicated under “Special Payment Instructions,” please issue the check for the purchase price of all of the Shares purchased and, if appropriate, return a statement of book entry shares evidencing Shares not tendered or not accepted for payment in the name(s) of the registered holder(s) appearing above under “Description of Shares Tendered.” Similarly, unless otherwise indicated under “Special Delivery Instructions,” please mail the check for the purchase price of all of the Shares purchased and, if appropriate, return a statement of book entry shares evidencing Shares not tendered or not accepted for payment (and any accompanying documents, as appropriate) to the address(es) of the registered holder(s) appearing above under “Description of Shares Tendered.” In the event that the boxes entitled “Special Payment Instructions” and “Special Delivery Instructions” are both completed, please issue the check for the purchase price of all Shares purchased and, if appropriate, return a statement of book entry shares evidencing Shares not tendered or not accepted for payment (and any accompanying documents, as appropriate) in the name(s) of, and deliver such check and, if appropriate, return any such statements (and any accompanying documents, as appropriate) to, the person(s) so indicated. The undersigned recognizes that Purchaser has no obligation, pursuant to the “Special Payment Instructions,” to transfer any Shares from the name of the registered holder thereof if Purchaser does not accept for payment any of the Shares so tendered.

INSTRUCTIONS

Forming Part of the Terms and Conditions of the Offer

1. Guarantee of Signatures. Except as otherwise provided below, all signatures on this Letter of Transmittal must be guaranteed by a financial institution (including most banks, savings and loan associations and brokerage houses) that is a member in good standing of a recognized Medallion Program approved by The Securities Transfer Association, Inc., including the Securities Transfer Agents Medallion Program (STAMP), the Stock Exchange Medallion Program (SEMP) and the New York Stock Exchange, Inc. Medallion Signature Program (MSP) or any other “eligible guarantor institution” (as such term is defined in Rule 17Ad-15 under the Securities Exchange Act of 1934, as amended) (each an “Eligible Institution”). Signatures on this Letter of Transmittal need not be guaranteed (i) if this Letter of Transmittal is signed by the registered holder(s) of the Shares tendered herewith (which term, for purposes of this document, shall include any participant in the Book-Entry Transfer Facility whose name appears on a security position listing as the owner of such Shares) and such holders have not completed either the box entitled “Special Payment Instructions” or the box entitled “Special Delivery Instructions” on this Letter of Transmittal or (ii) if Shares tendered herewith are tendered for the account of an Eligible Institution. See Instruction 5.

2. Requirements of Tender. This Letter of Transmittal is to be used either if certificates are to be forwarded herewith or, unless an Agent’s Message is utilized, if delivery of Shares is to be made by book-entry transfer pursuant to the procedures set forth in Section 3 of the Offer to Purchase. Certificates for all physically delivered Shares, or a confirmation of a book-entry transfer into the Depositary’s account at the Book-Entry Transfer Facility of all Shares delivered electronically, as well as a properly completed and duly executed Letter of Transmittal, together with any required signature guarantees (or, in the case of a book-entry transfer, an Agent’s Message) and any other documents required by this Letter of Transmittal, must be received by the Depositary at one of its addresses set forth on the front page of this Letter of Transmittal on or prior to the Expiration Date.

Stockholders whose certificates for Shares are not immediately available or stockholders who cannot deliver their certificates and all other required documents to the Depositary or who cannot comply with the procedures for book-entry transfer on or prior to the Expiration Date may tender their Shares pursuant to the guaranteed delivery procedure set forth in Section 3 of the Offer to Purchase.

Under the guaranteed delivery procedure:

(i) such tender must be made by or through an Eligible Institution;

(ii) a properly completed and duly executed Notice of Guaranteed Delivery substantially in the form made available by Purchaser with the Offer to Purchase must be received by the Depositary on or prior to the Expiration Date; and

(iii) the certificates for all physically delivered Shares, or a confirmation of a book-entry transfer into the Depositary’s account at the Book-Entry Transfer Facility of all Shares delivered electronically, as well as a properly completed and duly executed Letter of Transmittal with any required signature guarantee (or, in the case of a book-entry delivery, an Agent’s Message) and any other documents required by this Letter of Transmittal, must be received by the Depositary within two New York Stock Exchange trading days after the date of execution of such Notice of Guaranteed Delivery, all as provided in Section 3 of the Offer to Purchase.

The method of delivery of Shares, this Letter of Transmittal and all other required documents are at the election and sole risk of the tendering stockholder. Shares will be deemed delivered only when actually received by the Depositary (including, in the case of a book-entry transfer, upon receipt of a book-entry confirmation). If certificates for Shares are sent by mail, we recommend registered mail with return receipt requested, properly insured. In all cases, sufficient time should be allowed to ensure timely delivery.

10

No alternative, conditional or contingent tenders, and no fractional Shares, will be accepted for payment. By executing this Letter of Transmittal, the tendering stockholder waives any right to receive any notice of the acceptance for payment of the Shares.

3. Inadequate Space. If the space provided herein is inadequate, the certificate numbers and/or the number of Shares and any other relevant information should be listed on a separate signed schedule attached hereto.

4. Partial Tenders (not applicable to stockholders who tender by book-entry transfer). If fewer than all the Shares represented by any certificate delivered to the Depositary are to be tendered, fill in the number of Shares which are to be tendered in the box entitled “Number of Shares Tendered” under “Description of Shares Tendered” above. In such case, a statement evidencing book entry shares for the remainder of the Shares represented by the old certificate will be sent to the person(s) signing this Letter of Transmittal, unless otherwise provided in the appropriate box on this Letter of Transmittal, as promptly as practicable following the expiration or termination of the Offer. All Shares represented by certificates delivered to the Depositary and all the Shares held electronically through the Direct Registration System at the Depository will be deemed to have been tendered unless otherwise indicated.

5. Signatures on Letter of Transmittal; Stock Powers and Endorsements.

(a) Exact Signatures.

If this Letter of Transmittal is signed by the registered holder(s) of the Shares tendered hereby, the signature(s) must correspond with the name(s) as written on the face of the certificates without alteration, enlargement or any change whatsoever.

(b) Joint Holders.

If any of the Shares tendered hereby are held of record by two or more persons, all such persons must sign this Letter of Transmittal.

(c) Different Names on Certificates.

If any of the Shares tendered hereby are registered in different names on different certificates or (in the case of Shares not represented by certificates) in different accounts, it will be necessary to complete, sign and submit as many separate Letters of Transmittal as there are different registrations of Shares.

(d) When Endorsements or Stock Powers are Not Required.

If this Letter of Transmittal is signed by the registered holder(s) of the Shares tendered hereby, no endorsements of certificates or separate stock powers are required unless payment of the purchase price is to be made, or Shares not tendered or not accepted for payment are to be returned, in the name of any person other than the registered holder(s). Signatures on any such certificates or stock powers must be guaranteed by an Eligible Institution.

(e) When Endorsements or Stock Powers are Required.

If this Letter of Transmittal is signed by a person other than the registered holder(s) of the Shares tendered hereby, certificates must be endorsed or accompanied by appropriate stock powers, in either case, signed exactly as the name(s) of the registered holder(s) appear(s) on the certificates for such Shares. Signature(s) on any such certificates or stock powers must be guaranteed by an Eligible Institution. See Instruction 1.

(f) Evidence of Fiduciary or Representative Capacity.

If this Letter of Transmittal or any certificate or stock power is signed by a trustee, executor, administrator, guardian, attorney-in-fact, officer of a corporation or other person acting in a fiduciary or representative capacity,

11

such person should so indicate when signing, and proper evidence satisfactory to Purchaser of the authority of such person so to act must be submitted.

6. Stock Transfer Taxes. Purchaser (or any successor entity thereto) will pay any stock transfer taxes imposed on the sale and transfer of any Shares to it or its order pursuant to the Offer (for the avoidance of doubt, transfer taxes do not include U.S. federal income taxes or backup withholding taxes). If, however, payment of the purchase price is to be made to, or Shares not tendered or not accepted for payment are to be returned in the name of, any person other than the registered holder(s), or if a transfer tax is imposed for any reason other than the sale or transfer of Shares to Purchaser pursuant to the Offer, then the amount of any stock transfer taxes (whether imposed on the registered holder(s) or otherwise) will be deducted from the purchase price unless satisfactory evidence of the payment of such taxes, or exemption therefrom, is submitted.

Except as provided in this Instruction 6, it will not be necessary for transfer tax stamps to be affixed to the Share certificates listed in this Letter of Transmittal.

7. Special Payment and Delivery Instructions. If the check for the purchase price of any Shares purchased is to be issued, or any Shares not tendered or not accepted for payment are to be returned, in the name of a person other than the person(s) signing this Letter of Transmittal or if the check or any certificates for Shares not tendered or not purchased are to be mailed to someone other than the person(s) signing this Letter of Transmittal or to the person(s) signing this Letter of Transmittal at an address other than that shown above, the appropriate boxes on this Letter of Transmittal should be completed. The transferee must complete the IRS Form W-9 or applicable IRS Form W-8. Stockholders tendering Shares by book-entry transfer may request that Shares not accepted for payment be credited to such account at the Book-Entry Transfer Facility as such stockholder may designate under “Special Payment Instructions.” If no such instructions are given, any such Shares will be returned by crediting the account at the Book-Entry Transfer Facility designated above. To complete transfers using the “Special Payment Instructions” and/or “Special Delivery Instructions” above, you must also indicate a Transfer Reason under “Special Payment Instructions” above.

8. Tax Information and Backup Withholding. Under the U.S. federal income tax laws, unless certain certification requirements are met, the Depositary generally will be required to withhold at the applicable backup withholding rate (currently 24% as a result of a recent change in law) from any payments made to a stockholder pursuant to the Offer. In order to avoid such backup withholding, each tendering stockholder, and, if applicable, each other payee that is a United States Shareholder (as defined below), must provide the Depositary with such stockholder’s or payee’s correct taxpayer identification number and certify that such stockholder or payee is not subject to such backup withholding by completing the IRS Form W-9, which is included herein. In general, if a stockholder or payee is an individual, the taxpayer identification number is the social security number of such individual. If the stockholder or payee does not provide the Depositary with its correct taxpayer identification number, the stockholder or payee may be subject to a $50 penalty imposed by the IRS. Certain stockholders or payees (including, generally, domestic corporations and foreign stockholders) are not subject to these backup withholding and reporting requirements. In order to satisfy the Depositary that a stockholder that is not a United States Shareholder is exempt, such stockholder or payee must submit to the Depositary a properly completed appropriate IRS Form W-8, signed under penalties of perjury, attesting to that stockholder’s foreign status. IRS Forms W-8 can be obtained from the Depositary or the IRS (www.irs.gov/formspubs/index.html). The instructions on the enclosed IRS Form W-9 contain further information concerning backup withholding and instructions for completing the IRS Form W-9 (including how to obtain a taxpayer identification number if you do not have one and how to complete the IRS Form W-9 if Shares are held in more than one name).

Failure to provide an IRS Form W-9 or an appropriate IRS Form W-8, as applicable, will not, by itself, cause Shares to be deemed invalidly tendered, but may require the Depositary to withhold 24% of the amount of any payments made pursuant to the Offer. Backup withholding is not an additional U.S. federal income tax. Rather, the U.S. federal income tax liability of a person subject to backup withholding will be reduced by the amount of tax withheld. If withholding results in an overpayment of taxes, a refund may be obtained provided that the

12

required information is timely furnished to the IRS. Failure to complete and provide an IRS Form W-9 or an appropriate IRS Form W-8, as applicable, may result in backup withholding of 24% of any payments made to you pursuant to the Offer.

For purposes of these instructions, a “United States Shareholder” is (i) an individual who is a citizen or resident alien of the United States for United States federal income tax purposes, (ii) a corporation (including an entity taxable as a corporation for United States federal income tax purposes) or partnership (including an entity taxable as a partnership for United States federal income tax purposes) created under the laws of the United States, any state thereof or the District of Columbia, (iii) an estate the income of which is subject to United States federal income tax regardless of its source or (iv) a trust if (a) a court within the United States is able to exercise primary supervision over the administration of the trust and one or more United States persons have the authority to control all substantial decisions of the trust or (b) the trust has a valid election in effect under applicable Treasury regulations to be treated as a United States person.

9. Mutilated, Lost, Stolen or Destroyed Certificates. If the certificate(s) representing Shares to be tendered have been mutilated, lost, stolen or destroyed, stockholders should (i) complete this Letter of Transmittal and check the appropriate box above and contact the Depositary at (800) 522-6645 for further instructions on replacing your certificate(s). This Letter of Transmittal and related documents cannot be processed until the procedures for replacing lost, mutilated, destroyed or stolen certificates have been completed.

10. Requests for Assistance or Additional Copies. Requests for assistance or additional copies of the Offer to Purchase and this Letter of Transmittal may be obtained from the Information Agent at its address or telephone number set forth below.

11. Irregularities. All questions as to the validity, form, eligibility (including time of receipt) and acceptance for payment of any tender of Shares will be determined by Purchaser, in its sole discretion, which determination shall be final and binding on all parties. Purchaser reserves the absolute right to reject any and all tenders determined by Purchaser not to be in proper form or the acceptance for payment of which may, in the opinion of Purchaser’s counsel, be unlawful. Purchaser also reserves the absolute right to waive any defect or irregularity in the tender of any Shares of any particular stockholder, whether or not similar defects or irregularities are waived in the case of other stockholders. No tender of Shares will be deemed to have been validly made until all defects and irregularities have been cured or waived to Purchaser’s satisfaction. None of Purchaser, the Depositary, the Information Agent or any other person will be under any duty to give notification of any defects or irregularities in tenders or incur any liability for failure to give any such notification. Purchaser’s interpretation of the terms and conditions of the Offer (including this Letter of Transmittal and the instructions hereto) will be final and binding.

12. Waiver of Conditions. Subject to the terms and conditions of the Merger Agreement, the conditions of the Offer (other than the Minimum Condition and the Termination Condition) may be waived by Purchaser in whole or in part. See “Section 15—Conditions of the Offer” of the Offer to Purchase.

IMPORTANT: This Letter of Transmittal together with any signature guarantees, or, in the case of a book-entry transfer, an Agent’s Message, and any other required documents, must be received by the Depositary on or prior to the Expiration Date and either certificates for tendered Shares must be received by the Depositary or Shares must be delivered pursuant to the procedures for book-entry transfer, in each case on or prior to the Expiration Date, or the tendering stockholder must comply with the procedures for guaranteed delivery.
