In the event that CSRA becomes eligible to use Form S-3 under the Securities Act after twelve (12) calendar months following the Closing Date, CSRA shall use its commercially reasonable efforts to convert the Form S-1 Shelf to a Shelf Registration on Form S-3 (a “Form S-3 Shelf” and together with the Form S-1 Shelf, the “Shelf Registration Statement”). Subject to the terms of this Agreement, including any applicable Blackout Period, CSRA shall respond to any comments from the SEC as promptly as practicable and use its commercially reasonable efforts to cause the Shelf Registration Statement to be declared effective under the Securities Act as promptly as reasonably practicable after the filing thereof

and shall use its commercially reasonable efforts to keep such Shelf Registration Statement continuously effective under the Securities Act until the date that all Stockholder Registrable Securities covered by such Registration Statement are no longer Stockholder Registrable Securities (the period during which CSRA shall use its commercially reasonable efforts to keep the Shelf Registration Statement continuously effective under the Securities Act in accordance with this Section 2.1 the “Shelf Period”). CSRA shall notify the holders of Stockholder Registrable Securities named in the Shelf Registration Statement via facsimile or by email of the effectiveness of a Form S-1 Shelf promptly once CSRA telephonically confirms effectiveness with the SEC. CSRA shall file a final Prospectus with the SEC to the extent required by Rule 424. The “Plan of Distribution” section of such Shelf Registration Statement shall provide for all permitted means of disposition of Stockholder Registrable Securities requested in writing to be included therein by Providence including, if so requested in writing by Providence, firm commitment underwritten public offerings, agented transactions, sales directly into the market, purchases or sales by brokers and sales not involving a public offering.

Subject to Article 3 and the other terms and conditions of this Agreement, at any time during the Shelf Period Providence on behalf of the holders of Providence Registrable Securities may request to sell all or any portion of their Providence Registrable Securities in an offering that is registered pursuant to the Shelf Registration Statement (each, a “Shelf Takedown”). Providence may request CSRA to initiate up to five underwritten Shelf Takedowns. For the avoidance of doubt, there shall be no limit on resales by Providence pursuant to any Shelf Registration Statement that are not underwritten Shelf Takedowns. An offering using any such registration statement may be an Underwritten Offering if requested by Providence.

All requests for Shelf Takedowns shall be made only by Providence giving written notice to CSRA (a "Shelf Takedown Notice"). Each Shelf Takedown Notice shall specify the number of Providence Registrable Securities to be sold and the intended methods of disposition. Within one (1) Business Day after receipt of any Shelf Takedown Notice for an Underwritten Offering, CSRA shall give written notice of such requested underwritten Shelf Takedown (which notice shall state the material terms of such proposed Shelf Takedown, to the extent known) to all other holders of Stockholder Registrable Securities and, subject to the provisions of Section 2.4, shall include in such Shelf Takedown all Stockholder Registrable Securities with respect to which CSRA has received written requests for inclusion therein within two (2) Business Days after giving such notice; provided, that any such Stockholder Registrable Securities shall be sold subject to the same terms as are applicable to the Providence Registrable Securities. For the avoidance of doubt, a Shelf Takedown Notice may be given by Providence during a Blackout Period with such Shelf Takedown to occur immediately following the later of the expiration of the notice periods described in the preceding sentence or the next succeeding Business Day following expiration of the Blackout Period.

CSRA shall not include in any Shelf Takedown any securities that are not Stockholder Registrable Securities without the prior written consent of Providence; which consent shall not be unreasonably withheld, conditioned or delayed. In any Underwritten Offering, if the managing underwriter(s) advises CSRA in writing that in its opinion the number of Stockholder Registrable Securities and, if permitted hereunder, other securities requested to be included in such Underwritten Offering exceeds the number of Stockholder

Registrable Securities and other securities, if any, that can be sold therein in an orderly manner at a price that is acceptable to Providence, then CSRA shall include in such registration only such number of shares of CSRA Common Stock that in the opinion of the managing underwriter(s) can be sold in an orderly manner at a price that is acceptable to Providence, which shares shall be included in the following order of priority:

Providence shall have the right to select the underwriter or underwriters to administer any Underwritten Offering in connection with a sale of Stockholder Registrable Securities pursuant to a Shelf Takedown from a list to be supplied by CSRA, which list shall include at least 5 nationally recognized investment banking firms. If Providence wishes to select a lead underwriter that is not on the list provided by CSRA, Providence may propose an alternative lead underwriter; provided however that if CSRA objects in good faith to such alternative lead underwriter, CSRA may require Providence to select a different alternative lead underwriter after good faith consultation with CSRA, and, for the avoidance of doubt, CSRA may not object to such different alternative lead underwriter.

CSRA represents and warrants that it is not a party to, or otherwise subject to, any other agreement granting registration rights to any Person with respect to any securities of CSRA other than this Agreement.

CSRA will not be obligated to effect more than one underwritten Shelf Takedown in any 90 day period or more than three underwritten Shelf Takedowns in any 365 day period. CSRA shall not be obligated to effect any underwritten Shelf Takedown unless the reasonably anticipated gross proceeds from the sale of Providence Registrable Securities in such underwritten Shelf Takedown are $100 million. Notwithstanding anything in this Agreement to the contrary, no Stockholder Registrable Securities may be registered, offered,

sold or otherwise transferred under, and CSRA shall not be required to maintain the effectiveness of, more than one registration statement with respect to Stockholder Registrable Securities at any time nor shall CSRA be required, beginning six months after the Closing Date, to maintain a Shelf Registration Statement once the fair market value of all Stockholder Registrable Securities is less than $200 million in the aggregate.

Notwithstanding anything to the contrary contained in this Agreement, CSRA shall be entitled, from time to time, by providing written notice, to require any holder of Stockholder Registrable Securities to suspend the use of any Prospectus for sales of Stockholder Registrable Securities during any Blackout Period. After the expiration of any Blackout Period and without any further request from Providence, CSRA to the extent necessary shall as promptly as reasonably practicable and, if Providence has delivered a Shelf Takedown Notice during any Blackout Period, the next succeeding Business Day following such expiration, prepare and file a post-effective amendment or supplement to the Shelf Registration Statement or the Prospectus, or any document incorporated therein by reference, or file any other required document so that, as thereafter delivered to purchasers of the Stockholder Registrable Securities included therein, the Prospectus will not include an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

If CSRA proposes to register any of its CSRA Common Stock (whether or not in combination with any other equity or debt security or otherwise and whether or not in connection with a Shelf Registration) under the Securities Act (other than in connection with registration on Form S-4 or Form S-8 or any successor or similar forms, or relating solely to the sale of debt or convertible debt instruments) and the registration form to be used may be used for the registration of Stockholder Registrable Securities (a "Piggyback Registration"), CSRA shall give prompt written notice to the Stockholders of its intention to effect such a registration. Each such notice shall specify the approximate number of shares of CSRA Common Stock to be registered. Subject to Sections 4.2 and 4.3, if Stockholder Registrable Securities in the aggregate equal 2% or more of the outstanding shares of CSRA Common Stock, CSRA will include in such registration (and in all related registrations or qualifications under blue sky laws and in any related underwriting) all Stockholder Registrable Securities with respect to which CSRA has received a written request from any Stockholder for inclusion therein within 10 days after the delivery of such notice; provided that (i) each seller must sell its Stockholder Registrable Securities to the underwriter or underwriters selected by CSRA in connection with such offering on the same terms and conditions as apply to CSRA and (ii) if, at any time after giving notice to the relevant Stockholder of its intention to effect such registration, CSRA shall determine for any reason not to register any of its CSRA Common Stock under the Securities Act, CSRA shall give notice to the relevant Stockholder and thereupon shall be relieved of its obligation to register any Stockholder Registrable Securities in connection with such registration and, except for the obligation to pay Registration Expenses pursuant to Section 5.2 CSRA shall have no liability to the holders of Stockholder Registrable Securities in connection with such termination or withdrawal. CSRA shall have the right to select the underwriter or underwriters to administer any underwritten offering in connection with such registration and related offering.

If a Piggyback Registration is an underwritten primary registration on behalf of CSRA, and the managing underwriter(s) advises CSRA that in its opinion the number of securities requested to be included in such registration exceeds the number which can be sold in such offering in an orderly manner at a price that is acceptable to CSRA, CSRA will include in such registration only such number of shares of CSRA Common Stock that in the opinion of the managing underwriter(s) can be sold in an orderly manner at a price that is acceptable to CSRA, which shares shall be included in the following order of priority:

If a Piggyback Registration is an underwritten secondary registration on behalf of holders of CSRA Common Stock (other than the holders of Stockholder Registrable Securities), and the managing underwriter(s) advises CSRA in writing that in its opinion the number of securities requested to be included in such registration exceeds the number which can be sold in such offering in an orderly manner at a price that is acceptable to CSRA, CSRA will include in such registration only such number of shares of CSRA Common Stock that in the opinion of the managing underwriter(s) can be sold in an orderly manner at a price that is acceptable to CSRA, which shares shall be included in the following order of priority:

Without limiting its obligations in Section 2.1, CSRA will:

and any attorney or accountant retained by the relevant Stockholders or any managing underwriter, all material financial and other records and pertinent corporate and business documents of CSRA as will be reasonably necessary to enable them to exercise their due diligence responsibilities; provided that the relevant Stockholders, any such managing underwriter, attorney or accountant will enter into a confidentiality agreement satisfactory to CSRA;

customarily covered from time to time by legal opinions and negative assurance letters of such nature;

CSRA may require the Stockholders to furnish in writing to CSRA such information relating to the sellers of Stockholder Registrable Securities and the sale or registration of Stockholder Registrable Securities by the Stockholders and the distribution thereof as CSRA may from time to time reasonably request in writing. In the event of a Piggyback Registration, if within 10 days of the receipt of a written request from CSRA, the Stockholders fail to provide to CSRA any information relating to the Stockholders that is required by applicable law to be disclosed in any registration statement, CSRA may exclude the Stockholders' Stockholder Registrable Securities from such registration statement.

If any registration or comparable statement refers to any holder by name or otherwise as the holder of any securities of CSRA and if in such holder's sole and exclusive judgment, such holder is or might be deemed to be an underwriter or a controlling person of CSRA, such holder shall have the right to require the insertion therein of language, in form and substance satisfactory to such holder and presented to CSRA in writing, to the effect that the holding by such holder of such securities is not to be construed as a recommendation by such holder of the investment quality of CSRA's securities covered thereby and that such holding does not imply that such holder will assist in meeting any future financial requirements of CSRA.

All reasonable fees and expenses incurred in the performance of or compliance with this Agreement by CSRA including, without limitation, (i) all registration and filing fees (including, without limitation, fees and expenses (A) with respect to filings required to be made with the SEC, all applicable securities exchanges and/or FINRA and (B) of compliance with securities or blue sky laws, including, without limitation, any fees and disbursements of counsel for the underwriters in connection with blue sky qualifications of the Registrable Securities pursuant to Section 5.1(d)), (ii) printing expenses (including, without limitation, expenses of printing certificates for Registrable Securities in a form eligible for deposit with The Depository Trust Company and of printing prospectuses if the printing of prospectuses is requested by the managing underwriter(s), if any, or by a holder making a Shelf Registration with respect to such offering), (iii) messenger, telephone and delivery expenses of the Issuer, (iv) fees and disbursements of counsel for CSRA, (v) expenses of CSRA incurred in connection with any road show, (vi) fees and disbursements of all independent registered public accounting firms referred to in Section 5.1(n) hereof (including, without limitation, the expenses of any “cold comfort” letters required by this Agreement) and any other persons, including special experts retained by CSRA and (vii) fees and disbursements of separate counsel for Providence if it participating in the offering (which counsel shall be selected by such participating Holders) shall be borne by CSRA whether or not any Registration Statement is filed or becomes effective. In addition, CSRA shall pay its internal expenses (including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties), the expense of any annual audit, the fees and expenses incurred in connection with the listing of the securities to be registered on any securities exchange on which similar securities issued by CSRA are then listed and rating agency fees and the fees and expenses of any Person, including special experts, retained by CSRA.

such Person will forthwith discontinue the disposition of its Stockholder Registrable Securities pursuant to the registration statement until such Person's receipt of the copies of a supplemented or amended prospectus as contemplated by such Section 5.1(e), as the case may be. In the event CSRA shall give any such notice, the applicable time period mentioned in Section 5.1(b) during which a registration statement is to remain effective shall be extended by the number of days during the period from and including the date of the giving of such notice pursuant to this paragraph to and including the date when each seller of a Stockholder Registrable Security covered by such registration statement shall have received the copies of the supplemented or amended prospectus contemplated by Section 5.1(e).

At all times after the date of this Agreement, CSRA will timely file all reports required to be filed by it under the Securities Act and the Exchange Act and the rules and regulations adopted by the SEC thereunder at any time when CSRA is subject to such reporting requirements (or, if CSRA is not required to file such reports, it will, upon the request of Providence, make publicly available such information as necessary to permit sales of Stockholder Registrable Securities pursuant to Rule 144), all to the extent required to enable the Stockholders to sell Stockholder Registrable Securities pursuant to Securities Act Rule 144.

CSRA agrees to: (a) indemnify and hold harmless, to the fullest extent permitted by law, the Stockholders and, as applicable, their respective officers, directors, trustees, employees, unitholders, holders of beneficial interests, members, general and limited partners, agents and representatives and each Person who controls the Stockholders or such holder (within the meaning of the Securities Act) (collectively, "Stockholder Indemnitees") against any and all losses, claims, actions, damages, liabilities and expenses (including reasonable attorney's fees and expenses), to which the Stockholders or any such holder or Stockholder Indemnitee may become subject under the Securities Act or otherwise, insofar as such losses, claims, actions, damages, liabilities or expenses (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of, result from or are based upon (i) any untrue or alleged untrue statement of material fact contained in any registration statement of CSRA under the Securities Act that covers any Stockholder Registrable Securities pursuant to this Agreement, or prospectus or preliminary prospectus or any amendment thereof or supplement thereto relating to Stockholder Registrable Securities, together with any documents incorporated therein by reference, or (ii) any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus or preliminary prospectus, in the light of the circumstances under which they were made) not misleading; and (b) reimburse the Stockholders and each such holder and Stockholder Indemnitee for any legal or any other expenses as incurred, including any amounts paid in any settlement effected with the consent of CSRA, which consent will not be unreasonably withheld or delayed, reasonably incurred by them in connection with investigating or defending any such loss, claim, liability, action or proceeding; provided, however, that CSRA shall not be liable in any such case to the extent that any such loss, claim, action, damage, liability or expense (or action or proceeding in respect thereof) arises out of, results from or is based upon an untrue statement or alleged untrue statement, or omission or alleged omission, made in such registration statement, any such prospectus or preliminary prospectus or any amendment or supplement

thereto, in reliance upon, and in conformity with, written information prepared and furnished to CSRA by or on behalf of such holder with respect to such holder expressly for use therein.

In connection with any registration statement in which a holder of Stockholder Registrable Securities is participating, each such holder will furnish to CSRA in writing such information as CSRA reasonably requests for use in connection with any such registration statement, prospectus, preliminary or prospectus and, to the extent permitted by law, will indemnify and hold harmless, severally and not jointly, CSRA and its officers, directors, employees, agents, representatives, trustees and each Person who controls CSRA (within the meaning of the Securities Act) (collectively, the "CSRA Indemnitees") against any losses, claims, damages, liabilities and expenses (including reasonable attorney's fees and expenses) to which CSRA or any such CSRA Indemnitee may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages, liabilities and expenses (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of, result from or are based upon (a) any untrue or alleged untrue statement of material fact contained in any registration statement of CSRA under the Securities Act that covers any Stockholder Registrable Securities pursuant to this Agreement, or prospectus, preliminary prospectus or Free Writing Prospectus or any amendment thereof or supplement thereto relating to Stockholder Registrable Securities, together with any documents incorporated therein by reference, or (b) any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, preliminary prospectus or Free Writing Prospectus, in the light of the circumstances under which they were made) not misleading, but, in the case of each of (a) and (b), only to the extent that such untrue statement (or alleged untrue statement) or omission (or alleged omission) is made in such registration statement, any such prospectus, preliminary prospectus or Free Writing Prospectus or any amendment thereof or supplement thereto, together with any documents incorporated therein by reference, in reliance upon and in conformity with written information prepared and furnished to CSRA by or on behalf of such holder with respect to such holder expressly for use therein. In addition, such holder will reimburse CSRA and each such CSRA Indemnitee for any legal or any other expenses as incurred including any amounts paid in any settlement effected with the consent of such holder, which consent will not be unreasonably withheld or delayed, incurred by them in connection with investigating or defending any such loss, claim, liability, action or proceeding. The liability of any holder of Stockholder Registrable Securities shall be several and not joint and shall be limited to the net proceeds after underwriting commissions and discounts (but before any taxes and expenses which may be payable by such holder) received by such holder from the sale of Stockholder Registrable Securities covered by such registration statement, less any other amounts paid by such holder to CSRA and each such CSRA Indemnitee in respect of such untrue statement, alleged untrue statement, omission or alleged omission.

Any Person entitled to indemnification hereunder will (a) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided, that the failure of any indemnified party to give such notice shall not relieve the indemnifying party of its obligations hereunder, except to the extent that the indemnifying party is actually prejudiced by such failure to give such notice), and (b) unless in such indemnified party's reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party will not be subject to any liability for any settlement made by

the indemnified party without its consent (but such consent will not be unreasonably withheld). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim will not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim.

The indemnifying party shall not, except with the approval of each indemnified party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof, the giving by the claimant or plaintiff to each indemnified party of a release from all liability in respect to such claim or litigation without any payment or consideration provided by such indemnified party.

If the indemnification provided for in this Article 6 is, other than expressly pursuant to its terms, unavailable to or is insufficient to hold harmless an indemnified party under the provisions above in respect of any losses, claims, damages, liabilities or expenses referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities or expenses in such proportion as is appropriate to reflect the relative fault of CSRA on the one hand and of the sellers of Stockholder Registrable Securities and any other sellers participating in the registration statement on the other hand in connection with the statement or omissions which resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the sellers of Stockholder Registrable Securities and any other sellers participating in the registration statement shall be deemed to be the total net proceeds from the offering (before deducting expenses) to the sellers of Stockholder Registrable Securities and any other sellers participating in the registration statement. The relative fault of CSRA on the one hand, and of the sellers of Stockholder Registrable Securities and any other sellers participating in the registration statement on the other hand, shall be determined by reference to, among other things, whether the untrue or alleged statement or omission to state a material fact relates to information supplied by CSRA or by the sellers of Stockholder Registrable Securities or other sellers participating in the registration statement and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

CSRA and the sellers of Stockholder Registrable Securities agree that it would not be just and equitable if contribution pursuant to this Article 6 were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities and expenses referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Article 6, no seller of Stockholder Registrable Securities shall be required to contribute any amount in excess of the net proceeds received by the Stockholders from the sale of Stockholder Registrable Securities covered by the registration statement filed pursuant hereto, less any other amounts paid by the Stockholders in respect of such untrue statement, alleged untrue statement, omission or alleged omission. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the

Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation.

The indemnification and contribution by any such party provided for under this Agreement shall be in addition to any other rights to indemnification or contribution which any indemnified party may have pursuant to law or contract and will remain in full force and effect regardless of any investigation made or omitted by or on behalf of the indemnified party or any officer, director or controlling Person of such indemnified party and will survive the transfer of Stockholder Registrable Securities and the termination or expiration of this Agreement.

The indemnification provided for under this Agreement will remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, agent or employee and each other Person who participates as an underwriter in the offering or sale of such securities and each other Person, if any, who controls (within the meaning of the Securities Act) such indemnified party, and will survive the transfer of securities.

This Agreement will be effective as of the date hereof and will continue in effect thereafter until the earliest of: (a) its termination by the written consent of the parties hereto or their respective successors in interest; (b) the date on which Stockholder Registrable Securities comprise fewer than 2% of the outstanding shares of CSRA Common Stock; or (c) the dissolution, liquidation or winding up of CSRA.

CSRA will not hereafter grant any registration rights with respect to its securities that violate or are materially more favorable than the rights granted to the holders of Stockholder Registrable Securities in this Agreement.

The parties hereto agree and acknowledge that money damages may not be an adequate remedy for any breach of the provisions of this Agreement and that, in addition to any other rights and remedies at law or in equity existing in its favor, any party shall be entitled to specific performance and/or other injunctive relief from any court of law or equity of competent jurisdiction (without posting any bond or other security) in order to enforce or prevent violation of the provisions of this Agreement.

Capitalized terms used in this Agreement that are not defined in Section 1.1 have the meanings specified elsewhere in this Agreement. Defined terms used in this Agreement in the singular shall import the plural and vice versa. Whenever the context may require, any pronoun shall include the corresponding masculine, feminine and neuter forms. All references herein to Sections shall be deemed to be references to Sections

of this Agreement unless the context shall otherwise require. The words "include," "includes" and "including" shall be deemed to be followed by the phrase "without limitation." The words "hereof," "herein" and "hereunder" and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not to any particular provision of this Agreement. Any statute or laws defined or referred to herein shall include any rules, regulations or forms promulgated thereunder from time to time and as from time to time, amended, amended and restated, modified or supplemented, including by succession of comparable rules, regulations or forms. Unless otherwise expressly provided herein, any agreement, instrument or statute defined or referred to herein or in any agreement or instrument that is referred to herein means such agreement, instrument or statute as from time to time amended, amended and restated, modified or supplemented, including (in the case of agreements or instruments) by waiver or consent and (in the case of statutes) by succession of comparable successor statutes and references to all attachments thereto and instruments incorporated therein. Any reference to the number of shares of capital stock of CSRA means such shares of capital stock of CSRA as appropriately adjusted to give effect to any share combinations or exchanges, restructuring or other recapitalizations of CSRA or its capital structure. Any reference herein to the holder of a particular class or series of capital stock of CSRA shall be a reference to such Person solely in its capacity as a holder of that particular class or series of such capital stock of CSRA.

This Agreement may be amended, modified, extended, terminated or waived (an "Amendment"), and the provisions hereof may be waived, only by an agreement in writing signed by CSRA and Providence. Each such Amendment shall be binding upon each party hereto. In addition, each party hereto may waive any right hereunder, as to itself, by an instrument in writing signed by such party. The failure of any party to enforce any provisions of this Agreement shall in no way be construed as a waiver of such provisions and shall not affect the right of such party thereafter to enforce each and every provision of this Agreement in accordance with its terms. To the extent the Amendment of any Section of this Agreement would require a specific consent pursuant to this Section 7.5, any Amendment to the definitions used in such Section as applied to such Section shall also require the same specified consent.

This Agreement shall be binding upon and inure to the benefit of and be enforceable by the parties hereto and their respective successors and assigns. Stockholder Registrable Securities shall cease to be Stockholder Registrable Securities after any Transfer to any Person other than a Permitted Transferee. Prior to the Transfer of any Stockholder Registrable Securities to any Permitted Transferee, and as a condition thereto, each Stockholder proposing to effect such Transfer shall cause such Permitted Transferee to deliver to CSRA its written agreement, in form and substance reasonably satisfactory to CSRA, to be bound by the terms and conditions of this Agreement.

Whenever possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability shall not affect any other provision or the effectiveness or validity of any provision in

any other jurisdiction, and this Agreement shall be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable provision had never been contained herein.

This Agreement may be executed in separate counterparts (including by means of facsimile or electronic transmission in portable document format), each of which shall be an original and all of which taken together shall constitute one and the same Agreement.

The descriptive headings of this Agreement are inserted for convenience only and do not constitute a part of this Agreement. The parties hereto agree that they have been represented by counsel during the negotiation and execution of this Agreement and have participated jointly in the drafting of this Agreement and, therefore, waive the application of any law, holding or rule of construction providing that ambiguities in an agreement or other document will be construed against the party drafting such agreement or document.

Any notices and other communications required or permitted in this Agreement shall be effective if in writing and (a) delivered personally, (b) sent by facsimile, or (c) sent by overnight courier, in each case, addressed as follows:

with copies to (which shall not constitute notice):

Allen & Overy LLP

and

with a copy to (which shall not constitute notice):

Debevoise & Plimpton LLP

and

with a copy to (which shall not constitute notice):

Debevoise & Plimpton LLP

If to any other Person, to it at the address set forth in the records of CSRA.

Notice to the holder of record of any capital stock shall be deemed to be notice to the holder of such shares for all purposes hereof.

Unless otherwise specified herein, such notices or other communications shall be deemed effective (x) on the date received, if personally delivered, (y) on the date received if delivered by facsimile on a Business Day, or if not delivered on a Business Day, on the first Business Day thereafter, and (z) two Business Days after being sent by overnight courier. Each of the parties hereto shall be entitled to specify a different address by giving notice as aforesaid to each of the other parties hereto.

This Agreement and any signed agreement or instrument entered into in connection herewith or contemplated hereby, and any amendments hereto or thereto, to the extent signed and delivered by means of a facsimile machine or electronic mail, shall be treated in all manner and respects as an original agreement or instrument and shall be considered to have the same binding legal effect as if it were the original signed version thereof delivered in person. At the request of any party hereto or to any such agreement or instrument, each other party hereto or thereto shall re-execute original forms thereof and deliver them to all other parties. No party hereto or to any such agreement or instrument shall raise the use of a facsimile machine or electronic mail to deliver a signature or the fact that any signature or agreement or instrument was transmitted or communicated through the use of a facsimile machine or electronic mail as a defense to the formation or enforceability of a contract and each such party forever waives any such defense.

No delay of or omission in the exercise of any right, power or remedy accruing to any party as a result of any breach or default by any other party under this Agreement shall impair any such right, power or remedy, nor shall it be construed as a waiver of or acquiescence in any such breach or default, or of any similar breach or default occurring later; nor shall any such delay, omission nor waiver of any single breach or default be deemed a waiver of any other breach or default occurring before or after that waiver.

If, from time to time, there is any change in the capital structure of CSRA by way of a split, dividend, combination or reclassification, or through a merger, consolidation, reorganization or recapitalization, or

by any other means, appropriate adjustment shall be made in the provisions hereof so that the rights and privileges granted hereby shall continue.

IN WITNESS WHEREOF, the Parties hereto have caused this Agreement to be signed by their respective officers thereunto duly authorized, as of the date first written above.
