PARTICIPATION

3.1 Designation by Deferral Authority. The Deferral Authority in its sole discretion shall designate those Employees or Directors who are to be eligible to participate in the Plan with respect to Deferrals for a particular Plan Year or with respect to a particular Deferrable Amount or Amounts. Designating an individual as eligible to participate in the Plan for a particular Plan Year or with respect to a particular Deferrable Amount shall not require the Deferral Authority to designate such individual for any subsequent Plan Year or with respect to any subsequent Deferrable Amounts. The designation of eligibility by the Deferral Authority may be made in such manner as determined by the Deferral Authority, including, without limitation, establishment of criteria such as compensation level or level or authority.

3.2 Deferral Elections.

(a) An eligible Employee or Director shall not become a Participant in the Plan unless and until he or she has executed and delivered to the Committee a Deferral election, including any forms or agreements as may be prescribed by the Committee, and the Committee shall have accepted such Deferral election and/or additional forms or agreements. Participation in the Plan and any elections made by a Participant, including Deferral elections and elections as to form of distribution under Article VII, is conditioned on the Participant executing an agreement with the Company, in a manner prescribed by the Committee, relating to the Company’s right of repurchase of Company Stock (to the extent applicable) and such other matters as the Committee shall prescribe. To initially participate in the Plan, the Employee or Director must submit his or her Deferral election, including any forms or agreements prescribed by the Committee, during the applicable Deferral election period established by the Committee. Effective for Deferrals on or after January 1, 2005, the last day of the Deferral election period for any Deferrable Amount other than “performance-based compensation” (as defined below) shall be no later than the last day of the calendar year prior to the first calendar year during which the Employee or Director performs services for which such Deferral Amount is earned. Beginning with the Deferral election made in the 2003 Plan Year for Deferrable Amounts received during calendar year 2004, the Participant’s election shall be carried forward automatically to future Plan Years for which the Participant is eligible to participate unless, during the applicable Deferral election period for such future Plan Years, the Participant elects to modify or cancel the prior election under procedures established by the Committee. In addition to amounts deferred pursuant to a Deferral election, additional Deferrals may be credited to a Participant’s Account pursuant to the terms of an offer letter with an Employee made at the time of commencement of employment with the

4

Company, as determined and approved by the Deferral Authority in its sole discretion. Furthermore, the Committee may, to the extent consistent with satisfying Code Section 409A, permit an Employee or Director to make a Deferral Election within 30 days of the date such Employee or Director first becomes eligible to participate in the Plan, as indicated by the effective date of his status change in the Plan’s records. Such a Deferral election shall be with respect to compensation earned for services performed after the election.

(b) If a Deferrable Amount constitutes “performance-based compensation,” then the Committee may, but need not, delay the last day of the Deferral election period. The last day of the Deferral election period with respect to any Deferrable Amount which is considered to be performance-based compensation shall be no later than six months before the end of the service period over which such Deferrable Amount is earned. For this purpose, “performance-based compensation” means compensation where the amount of or entitlement to the compensation is contingent on the satisfaction of pre-established written performance criteria relating to a performance period of at least twelve consecutive months, provided that performance-based compensation does not include any amount that will be paid regardless of performance, or based upon a level of performance that is substantially certain to be met at the time the criteria is established. Performance-based compensation must also meet any other applicable requirements established under authority issued pursuant to Code Section 409A.

3.3 Amounts Subject to Deferral. The total Deferrals elected for a particular Plan Year may be in an amount up to a specified percentage of Deferrable Amounts, such maximum percentage to be up to one hundred percent (100%) as determined by the Deferral Authority.

3.4 Deferral Election Irrevocable. Any Deferral election by a Participant for a particular Plan Year shall be irrevocable for that Plan Year following the end of such Plan Year’s Deferral election period.

3.5 Deferrals May be Held in Trust.

(a) With respect to Deferrals before January 1, 2005, within a reasonable period of time following the date on which a Deferrable Amount would have been paid to a Participant but for the Deferral hereunder, the Company shall contribute, to the Trust, Company Stock or money in an amount sufficient to purchase shares of Company Stock equal in value (based, prior to any public offering of Company Stock, on the then prevailing Formula Price as determined under the Company’s Certificate of Incorporation) to the Deferral. The Trustee shall apply such contribution toward the purchase of Company Stock in accordance with the directions of the Committee and the terms of the Trust and the Participant shall be credited with the applicable number of Share Units.

(b) Effective January 1, 2005, contributions to the Trust with respect to Deferrals shall be made only if the Company, in its sole discretion, determines to make such contributions. Regardless of whether the Company makes contributions to the Trust with respect to Deferrals, the Participant shall be credited with a number of Share Units equal to the Deferral. If it becomes necessary to determine the value of a full or partial Share Unit prior to any public offering of Company Stock, such value shall be based on the then prevailing Formula Price (as determined under the Company’s Certificate of Incorporation) as of the date the Deferrable Amount

5

would have been paid to the Participant but for the Deferral hereunder. Following any public offering of Company Stock, such value shall be determined according to the Fair Market Value of the Company Stock as of the date the Deferrable Amount would have been paid to the Participant but for the Deferral hereunder.

ARTICLE IV

TRUST FUND

4.1 Trust Fund Established. The Company has established the Trust pursuant to a trust agreement under which the Trustee will hold and administer in trust all assets deposited with the Trustee in accordance with the terms of this Plan. The Board shall have the authority to select and remove the Trustee to act under the Trust agreement, and to enter into new or amended trust agreements as it deems advisable.

4.2 Company, Board, Deferral Authority, Committee and Trustee Not Responsible for Adequacy of Trust Fund. Neither the Company, Board, Deferral Authority, Committee nor Trustee shall be liable or responsible for the adequacy of the funds held in the Trust to meet and discharge any or all payments and liabilities hereunder. All Plan benefits will be paid from the Trust assets or by the Company to the extent not paid from Trust assets, and neither the Board, Deferral Authority, Committee nor Trustee shall have any duty or liability to pay such benefits or furnish the Trust with any funds, securities or other assets.

4.3 Invasion of Trust by Creditors. If assets of the Trust should be reduced due to action of the Company’s creditors, as provided in the Trust document, the Committee shall reduce each Account for which the Trust held assets on a pro rata basis to reflect such reduction in Trust assets, and the Company shall have no obligation to replace such lost assets.

4.4 Trust Expenses. Expenses of the Trust which are not paid by the Company shall be applied to reduce each Account for which the Trust holds assets on a pro rata basis.

ARTICLE V

ACCOUNTS

5.1 Committee to Maintain Accounts. The Committee shall open and maintain a separate Account for each Participant to record the Deferrals made by the Participant and the number of Share Units credited as a result of the Deferrals.

5.2 Additional Accounting Procedures. The Committee shall establish and may amend from time to time additional accounting procedures for the purpose of making allocations, distributions, valuations and adjustments to Accounts, and to allocate Trust earnings expenses and losses to such accounts. A Participant or Beneficiary shall have no contractual or other right to have a particular accounting procedure or convention apply, or continue to apply, and the Committee shall be free to alter any such procedure or convention without notice or obligation to any Participant or Beneficiary.

6

5.3 Limitation on Benefits. Benefits payable to a Participant or Beneficiary under the Plan shall be limited to the vested Account balance credited to such Participant or Beneficiary.

5.4 Vesting of Account Balances. A Participant’s Account balance shall be one hundred percent (100%) vested except with respect to the portion of the Account balance attributable to vesting bonuses awarded under the Bonus Compensation Plan. Such portion of a Participant’s Account balance shall become vested (and the nonvested portion forfeited) at the time or times the bonus would have become vested (and the nonvested portion forfeited) under the Bonus Compensation Plan without regard to deferral under this Plan. The Share Units represented by such forfeited portion shall be returned to the Company or reallocated in accordance with the Committee’s directions and the terms of the Trust.

ARTICLE VI

RIGHTS IN ACQUIRED STOCK

6.1 Power to Vote Stock Rests With Trustee. The power to vote any stock held by the Trustee shall rest solely with the Trustee, who shall vote such stock in the same proportion that the other shareholders vote their shares of stock of the Company. For purposes of this Section 6.1, in determining how other shareholders voted, the Trustee shall take into account the votes of shareholders with respect to all classes of voting stock, including but not limited to Class A and Class B Common Stock.

6.2 Tender Offers. In the case of a tender offer for the Company Stock, the Trustee shall tender the shares of Company Stock held by the Trust only if more than fifty percent (50%) of the shares of Company Stock held outside the Trust are tendered by the shareholders.

6.3 Dividends. All Ordinary Dividends on Company Stock held in Trust shall be held by the Trustee and reinvested as directed by the Committee. The Committee shall allocate such Ordinary Dividends among the Accounts pro rata to the shares allocated to each Account. The Capital Restructuring Dividend on Company Stock held in Trust shall be immediately disbursed by the Trustee to the Company for immediate distribution by the Company to Participants in accordance with Section 7.7. No person (including, but not limited to, the Trustee, the Company, the Committee or the Board) shall have the authority or ability to delay the immediate transfer of the Capital Restructuring Dividend from the Trustee to the Company pursuant to this Section 6.3.

ARTICLE VII

DISTRIBUTIONS

7.1 Time of Commencement of Distribution. Subject to the acceleration provisions of Article VIII, the balance credited to a Participant’s Account shall be distributed, or commence to be distributed, to the Participant on the first to occur of the following events:

(a) the Participant’s Retirement Date; or

(b) the date of the Participant’s Termination of Affiliation with the Company.

7.2 Form of Distribution. Each distribution shall be made in the form of Company Stock, except that fractional Share Units shall, as determined according to procedures established by the Committee, be distributed in kind as fractional shares or applied towards satisfying tax withholding obligations with respect to Participants’ distributions. A Participant shall have no right to request a cash distribution.

7.3 Methods of Distribution.

(a) Lump Sum on Death. If a Participant dies having an Account balance (regardless of whether distributions have begun under the Plan), the remaining balance in the Participant’s Account shall be paid in the form of a lump sum to the Beneficiary or Beneficiaries designated in accordance with Section 7.4, or as otherwise provided in Sections 7.4 and 7.5, within a reasonable period following the date when the Committee receives notice of the Participant’s death.

(b) Election for Retirement Distributions. Subject to the acceleration provisions in Article VIII, distributions made on account of a Participant’s Retirement Date shall be made to the Participant in accordance with a valid election made by the Participant under this subsection (b). The Participant may elect in a manner prescribed by the Committee to have his or her Account paid in one of the following forms:

(1) A lump sum payment of the entire Account Balance; or

(2) A series of annual payments over a five or ten year period. Each installment shall include one-fifth or one-tenth, as applicable, of the number of shares of Company Stock distributable to the Participant. Effective for new Participants making Deferral elections for the 2004 and subsequent Plan Years, a series of annual payments over a fifteen year period shall be an available option for Retirement distributions. Each installment shall include one-fifteenth of the number of shares of Company Stock distributable to the Participant.

In the event Participant elects a lump sum payment as described in Section 7.3(b)(1) and Participant has an Account balance attributable to vesting bonuses under the Bonus Compensation Plan that will continue vesting after such lump sum payment, additional distributions shall be made within a reasonable period of time following each date Share Units vest. In the event Participant

8

elects a series of annual payments as described in Section 7.3(b)(2) and Participant has an Account balance attributable to vesting bonuses under the Bonus Compensation Plan that will continue vesting after any annual distribution of Participant’s Account balance occurs, any Share Units that vest after a distribution will be added to the Account balance and distributed ratably over the remaining series of annual payments.

Effective January 1, 2005, a Participant’s election of the form of distribution shall be made at the time the Participant first makes a Deferral election. Such election of form of distribution shall be applicable to all subsequent Deferral elections by the Participant.

(c) Change of Distribution Election. Except as set forth in this Section 7.3(c), a Participant’s election of form of distribution shall be irrevocable. Each of the forms of distribution set forth in Section 7.3(b) shall be considered a single payment for purposes of Code Section 409A. Accordingly, Participants shall be allowed to make a new form of distribution election, provided that the following requirements are satisfied:

(1) the election does not take effect until at least twelve months after the date the election is made, and the election must be made at least twelve months prior to the date the first payment would be made to the Participant absent the election;

(2) the commencement date of the first payment to the Participant shall be five years following the date the payment would have commenced absent the change in the Participant’s election; and

(3) no Participant may make more than one new form of distribution election.

Any attempt to change a distribution election that does not satisfy these requirements shall be void.

(d) Other Distributions. Distributions other than those specified in (a) or (b) above shall be made as a lump sum within a reasonable period of time following a Participant’s Termination of Affiliation.

(e) Default Distribution. If the Participant fails to make a valid election as described in subsection (b), the Participant’s Account shall be distributed in full as a lump sum payment within a reasonable period of time following the Distribution Date. If Participant has an Account balance attributable to vesting bonuses under the Bonus Compensation Plan that will continue vesting after such lump sum payment is made, additional distributions shall be made within a reasonable period of time following each date Share Units vest.

(f) Notwithstanding the foregoing, if any stock of the Company is publicly traded on an established securities market, the distribution to any Participant who is a “specified employee” under Code Section 409A(a)(1)(B)(i) shall not be made (or commence to be made in the case of installment payments) before the earlier of (i) the date which is six months after such Participant’s Separation From Service or (ii) the date of the Participant’s death. For any twelve month period commencing April 1 and ending

9

March 31, a Employee is a “specified employee” if the Employee was a “key employee” at any time during the calendar year ending before such April 1. A key employee is defined in Code Section 416(i) without regard to Code Section 416(i)(5).

7.4 Beneficiary Designation.

(a) Upon forms provided by the Committee, each Participant shall designate in writing the Beneficiary or Beneficiaries whom such Participant desires to receive the benefits of this Plan, if any, payable in the event of such Participant’s death. A Participant may from time to time change his or her designated Beneficiary or Beneficiaries without the consent of such Beneficiary or Beneficiaries by filing a new designation in writing with the Committee. The Committee may rely upon the designation of Beneficiary or Beneficiaries last filed by the Participant in accordance with the terms of this Plan.

(b) If the designated Beneficiary does not survive the Participant, or if there is no valid Beneficiary designation, amounts payable under the Plan shall be paid to the Participant’s spouse, or if there is no surviving spouse, then to the duly appointed and currently acting personal representative of the Participant’s estate. If there is no personal representative of the Participant’s estate duly appointed and acting in that capacity within sixty (60) days after the Participant’s death, then all payments due under the Plan shall be payable to the person or persons who can verify by affidavit or court order to the satisfaction of the Committee that they are legally entitled to receive the benefits specified hereunder pursuant to the laws of intestate succession or other legal provision in effect at the Participant’s death in the jurisdiction having authority over disposition of the Participant’s estate.

7.5 Distribution to Guardian. If the Committee shall find that any person to whom any payment is payable under this Plan is unable to care for his or her affairs because of illness or accident, or is a minor, a payment due (unless a prior claim therefore shall have been made by a duly appointed guardian or other legal representative) may be paid to the spouse, a child, a parent, or a brother or sister, or to any custodian, conservator or other fiduciary responsible for the management and control of such person’s financial affairs in such manner and proportions as the Committee may determine. Any such payment shall, to the extent thereof, discharge of the liabilities of the Company to the Participant or Beneficiary under this Plan.

7.6 Withholding of Taxes. To the extent any distribution is subject to withholding taxes, the Committee shall require, as a condition to the payment of such distribution, that the taxes be withheld from such distribution by the Trustee, in which case the withheld amounts shall be delivered to the Company which shall pay over the withheld taxes as required by law; provided, however, that the Committee may, but need not, allow the Participant to make payment to the Company in the form of a check for such withholding taxes.

10

7.7 Distribution of Dividend Equivalents.

(a) Notwithstanding anything to the contrary in this Article VII, effective January 1, 2006, Dividend Equivalents with respect to the Capital Restructuring Dividend shall be distributed as set forth in this Section 7.7.

(b) Dividend Equivalents with respect to the Capital Restructuring Dividend shall be distributed by the Company to Participants as soon as administratively feasible upon the Company’s receipt of the Capital Restructuring Dividend from the Trustee in accordance with Section 6.3. No one (including, but not limited to, the Trustee, the Company, the Board, the Committee or any Participant) shall have the authority or the ability to delay the immediate distribution of Dividend Equivalents or alter the amount of Dividend Equivalents distributed with respect to the Capital Restructuring Dividend. The distribution of Dividend Equivalents with respect to the Capital Restructuring Dividend to be made to a Participant in accordance with this Section 7.7(b) shall equal the product of (i) the Participant’s Share Units as of the record date for the Capital Restructuring Dividend, times (ii) the per share Capital Restructuring Dividend. Immediate payment of the Dividend Equivalent upon the payment of the Capital Restructuring Dividend by the Company is intended to satisfy the requirement of Code Section 409A that payment be made as of a specified time or pursuant to a fixed schedule.

(c) Distributions of Dividend Equivalents with respect to the Capital Restructuring Dividend shall be made in cash without interest and shall be made from the Capital Restructuring Dividend paid to the Trust and transferred to the Company pursuant to Section 6.3.

ARTICLE VIII

ACCELERATION OF DISTRIBUTION

8.1 Change in Control. All Accounts shall be immediately distributed to the Participants to whom such Accounts belong, upon the occurrence of a Change in Control (as hereinafter defined) of the Company. A Change in Control shall be deemed to occur upon any “person” (as defined in Section 3(a)(9) of the United States Securities Exchange Act of 1934 (the “34 Act”)), other than the Company, any subsidiary or any employee benefit plan or trust maintained by the Company or subsidiary becoming the beneficial owner (as defined in Rule 13d-3 under the 34 Act), directly or indirectly, of more than 25% of the Company Stock outstanding at such time, without the prior approval of the Board. For purposes of the foregoing, a subsidiary is any corporation in an unbroken chain of corporations beginning with the Company if each of the corporations, other than the last corporation in such chain, owns at least fifty percent (50%) of the total voting power in one of the other corporations in such chain. Effective January 1, 2005, 35% shall be substituted for 25% in the above definition of Change in Control, in accordance with Code Section 409A.

11

8.2 Hardship.

(a) Prior to January 1, 2005, notwithstanding the provisions of Section 7.1 and 7.3 hereof, a Participant shall be entitled to request a hardship distribution of all or any portion of his or her Account. A Participant or legal representative of the Participant must make a written request for a hardship distribution, stating the reasons such withdrawal is necessary because of a financial hardship. The Committee, in its sole discretion, shall determine whether or not to grant the hardship distribution of such Participant’s Account and, in so doing, may rely on the Participant’s statements, and a hardship distribution may be approved without further investigation unless the Committee has reason to believe such statements are false.

(b) Effective January 1, 2005, a withdrawal under this Section 8.2 shall be permitted only if the Participant incurs an “unforeseeable emergency,” as defined below. Any such distribution shall be limited to the amount for which distribution is reasonably necessary to satisfy the emergency need (which may include amounts necessary to pay any Federal, State or local income taxes or penalties reasonably anticipated to result from the distribution). For purposes of this Section 8.2(b), an “unforeseeable emergency” is a severe financial hardship of the Participant resulting from (i) an illness or accident of the Participant, the Participant’s spouse or dependent, (ii) the loss of the Participant’s property due to casualty (including the need to rebuild a home following damage to a home to the extent not otherwise covered by insurance, or (iii) other similar extraordinary and unforeseeable circumstances arising as a result of events beyond the control of the Participant. The determination of whether an Participant has an unforeseeable emergency shall be made in accordance with the authorities published pursuant to Code Section 409A.

ARTICLE IX

SOURCE OF PAYMENT

9.1 No Direct Interest in Trust Assets. All distributions hereunder shall be paid solely from the Trust or from the assets of the Company, as determined by the Company. The Company shall pay any distributions not paid by the Trust. No special or separate funds shall be established and no other segregation of assets shall be made to assure the payment of benefits hereunder. A Participant shall have no right, title, or interest whatever in or to any investments which the Company may make through the Trust to meet its obligations hereunder. Nothing contained in this Plan, and no action taken pursuant to its provisions, shall create or be construed to create any kind of a fiduciary relationship between the Company and a Participant or any other person.

12

ARTICLE X

PLAN TERMINATION AND AMENDMENT

10.1 Termination and Amendments. The Plan shall continue until all amounts credited to the Participants’ Accounts have been distributed in accordance with the terms of the Plan. Notwithstanding the foregoing sentence, the Company retains the right to amend or terminate the Plan for any reason, including but not limited to adverse changes in tax laws or the bankruptcy, receivership or dissolution of the Company. In the event of a Plan termination, benefits will be paid out when due under the terms of the Plan. To the extent feasible, the Committee shall use its best efforts to avoid adversely affecting the rights of any existing Participants in the Plan, but prior to a Change in Control, the Committee shall be under no specific duty or obligation in this regard. Following a Change in Control no amendment or termination of the Plan shall adversely affect any benefits earned by Participants prior to the amendment or termination.

ARTICLE XI

PLAN ADMINISTRATION

11.1 Committee. The Plan shall be administered by the Committee. Subject to the provisions of the Plan and the authority granted to the Deferral Authority, the Committee shall have exclusive power to determine the manner and time of Deferrals and payment of benefits to the extent herein provided and to exercise any other discretionary powers granted to the Committee pursuant to the Plan.

The Committee, the Deferral Authority, the Board, or the Company may require satisfactory proof of any matter under this Plan from or with respect to any Employee, director, consultant, Participant or Beneficiary, and no such person shall acquire any rights or be entitled to receive any benefits under this Plan until such proof shall be furnished as so required.

11.6 Reliance on Committee Memorandum.

(b) This indemnification shall apply against expenses including, without limitation, attorneys fees and any expenses of establishing a right to indemnification hereunder, judgments, fines, settlements and other amounts actually and reasonably incurred in connection with such proceeding, except in relation to matters as to which he or she has acted fraudulently or in bad faith in the performance of such duties.

(c) The termination of any proceeding by judgment, order, settlement, conviction, upon a plea of nolo contendere or its equivalent shall not, in and of itself, create a presumption that the person acted fraudulently or in bad faith in the performance of his or her duties.

15

(d) Expenses incurred in defending any such proceeding may be advanced by the Company prior to the final disposition of such proceeding, upon receipt of an undertaking by or on behalf of the recipient to repay such amount, unless it shall be determined ultimately that the recipient is entitled to be indemnified as authorized in this Section 11.8.

ARTICLE XII

MISCELLANEOUS PROVISIONS

12.1 Restrictions on Plan Interest.

(a) A Participant’s interest in this Plan shall be limited to his or her Account and he or she shall have no other interest in any assets of the Company nor any right as against the Company, Deferral Authority or Committee for payment of benefits under this Plan.

(b) None of the benefits, payments, proceeds, claims or rights hereunder of any Participant or Beneficiary shall be subject to any claim of any creditor of such Participant or Beneficiary and in particular the same shall not be subject to attachment, garnishment, or other legal process by any creditor of such Participant or Beneficiary.

(c) A Participant or Beneficiary shall not have any right to alienate, anticipate, commute, pledge, encumber, or assign any of the benefits or payments or proceeds which he or she may expect to receive, contingently or otherwise, under the Plan.

(d) A Participant’s and Beneficiary’s interest in this Plan and his or her Account in the Trust are subject to the claims of the Company’s creditors as provided in the Trust. Each Participant and Beneficiary shall, however, be considered a general creditor of the Company with respect to his or her Account, so that if the Company should become insolvent, the Participant or Beneficiary will have a claim against the Company and Trust assets equal to that of the Company’s other general creditors (regardless of whether assets are removed from the Trust by a trustee in bankruptcy).

(e) Whenever a provision of this Plan restricts or limits a Participant or a Participant’s Account, benefit or distribution, such limitation shall also apply to a Beneficiary unless otherwise specified.

16

12.2 No Enlargement of Employee Rights.

(a) This Plan is strictly a voluntary undertaking on the part of the Company and shall not be deemed to constitute a contract between the Company and any Employee or Director, or be consideration for, or an inducement to, or a condition of, the employment of any Employee or affiliation of any Director.

(b) The employment of any Employee is not for any specified term and may be terminated by any Employee or by the Company at any time, for any reason, with or without cause. Nothing contained in the Plan shall be deemed to give any Employee the right to be retained in the employ of the Company, to constitute any promise or commitment by the Company regarding future positions, future work assignments, future compensation or any other term or condition of employment or to interfere with the right of the Company to discharge or retire any Employee at any time.

(c) No person shall have any right to any benefits under this Plan, except to the extent expressly provided herein.

12.3 Rights of Repurchase and First Refusal for the Company. Any Company Stock distributed from the Plan may be subject to a right of repurchase and right of first refusal by the Company, as well as any conditions, limitations or restrictions contained in an agreement specified in Section 3.2. The terms and conditions of the right of repurchase and right of first refusal to the extent applicable, shall be in addition to those applied to Company Stock by the Restated Certificate of Incorporation of Science Applications International Corporation, as amended.

12.4 Mailing of Payments. All payments under the Plan shall be delivered in person or mailed to the last address of the Participant (or, in the case of the death of the Participant to that of any other person entitled to such payments under the terms of the Plan). Each Participant shall be responsible for furnishing the Committee with his or her correct current address and the correct current name and address of his or her Beneficiary.

12.5 Inability to Locate Participant or Beneficiary. In the event that the Committee is unable to locate a Participant or Beneficiary to whom benefits are payable hereunder after mailing a notice to the Participant’s or Beneficiary’s last known address, and such inability lasts for a period of three (3) years, then any remaining benefits payable hereunder shall be forfeited to the Company and no Participant or Beneficiary shall have any right to further benefits from the Plan, even if subsequently located.

12.6 Governing Law. All legal questions pertaining to the Plan shall be determined in accordance with the laws of California, excluding its rules governing conflicts of laws. Without limiting Section 12.9, it is intended that this Plan be administered and interpreted in a manner consistent with the applicable requirements of Code Section 409A, and further that the Plan be interpreted in a manner that satisfies the applicable requirements of Rule 16b-3 promulgated under the Securities Exchange Act of 1934, so that elective deferrals will be entitled to the benefits of Rule 16b-3 or other exemptive rules under Section 16 of the Exchange Act and will not be subjected to avoidable liability thereunder.

17

12.7 Illegality of Particular Provision. If any particular provision of this Plan shall be found to be illegal or unenforceable, such provision shall not affect the other provisions thereof, but the Plan shall be construed in all respect as if such invalid provision were omitted.

12.8 Interpretation. Section headings are for convenient reference only and shall not be deemed to be part of the substance of this instrument or in any way to enlarge or limit the contents of any article or section.

12.9 Tax Effects. The Company makes no representations or warranties as to the tax consequences to a Participant or to a Participant’s Beneficiary from Deferrals hereunder or the subsequent receipt of any benefits as a result thereof. Each Participant must rely solely on his or her own tax advisor with respect to the tax consequences arising from the Deferrals or the receipt of benefits hereunder, or from any other related transaction.

12.10 Receipt or Release. Any payment to any Participant or Beneficiary in accordance with the provisions of this Plan shall, to the extent thereof, be in full satisfaction of all claims against the Committee and the Company, and the Committee may require such Participant or Beneficiary, as a condition precedent to such payment, to execute a receipt and release to such effect.

12.11 Records. The records of the Company with respect to the Plan shall be conclusive on all Participants, Beneficiaries, and all other persons whomsoever.

12.12 Arbitration. Any person disputing a decision of the Committee shall submit such dispute to binding arbitration pursuant to the rules of the American Arbitration Association, to be held in San Diego County. In any arbitration with respect to a decision or action of the Committee taken before a Change in Control, the losing party in such arbitration proceedings shall bear the costs of arbitration, and each party shall bear its own attorneys’ fees. In any arbitration with respect to a decision or action of the Committee taken after a Change in Control, the Company shall bear the costs of arbitration (other than attorneys’ fees), and the arbitrator may make an award of attorneys’ fees; any such award shall be made according to the then-prevailing standards for judicial awards of attorneys’ fees applicable to civil actions brought under the Employee Retirement Income Security Act of 1974, as amended.

WHEREAS, the Plan is subject to Section 409A of the Internal Revenue Code of 1986, as amended, which generally restricts the ability of participants in the Plan to make changes to the manner in which their Plan benefits will be paid;

WHEREAS, transition rules announced by the Internal Revenue Service allow the Company to grant participants a limited right to make changes to the manner in which their Plan benefits will be paid; and

WHEREAS, certain provisions of the Plan do not conform with corresponding provisions of other plans maintained by the Company regarding the possible Capital Restructuring Dividend and tax withholding;

NOW, THEREFORE, the Plan is hereby amended, effective January 1, 2006, as follows:

1. Section 2.5 of the Plan, the definition of Capital Restructuring Dividend, is amended to read in its entirety as follows:

“2.5 Capital Restructuring Dividend. The non-recurring cash dividend paid by the Company in 2006 or 2007 on shares of Company Stock in connection with the Company’s capital restructuring and the initial public offering of Company Stock.”

2. A new subsection (g) to Section 7.3 of the Plan is added to read in its entirety as follows:

“(g) Notwithstanding Section 7.3(c), pursuant to a transition rule issued by the Internal Revenue Service under Code Section 409A, each Participant who had not had a Separation From Service as of December 31, 2006 shall be permitted to elect among the forms of distribution specified in Section 7.3(b) with respect to distributions made on account of the Participant’s Retirement Date. The elections under this Section 7.3(g) shall be made pursuant to rules prescribed by the Committee, but shall in no event be made after December 31, 2006.

The Committee may, but need not, allow the Participant to make payment to the Company in the form of a check for such withholding taxes, and the Committee may provide in its discretion for other methods of withholding acceptable to the Company.”

FURTHER RESOLVED, officers of the Company, or any delegate of such person, be, and each of them hereby is, authorized at any time and from time to time to do and perform any and all acts or things, including, without limitation, the execution and delivery any and all further agreements, documents, instruments or papers of whatever kind or nature, which such officers or any of them may consider necessary or desirable to effect the intent of any and all of the foregoing resolutions, and the performance of such other acts and things by any of such officers shall evidence conclusively and for all purposes that such officer or officers considered the same to be necessary or desirable as aforesaid and that such act or thing so done or performed was hereby authorized, and that all such acts or things heretofore performed by the officers of this Company are hereby ratified and approved.

Amendment Two

Science Applications International Corporation

Key Executive Stock Deferral Plan

Section 3.5(b) of the Plan is amended to read in its entirely as follows:

“(b) Effective January 1, 2005, contributions to the Trust with respect to Deferrals shall be made only if the Company, in its sole discretion, determines to make such contributions. Regardless of whether the Company makes contribution to the Trust with respect to Deferrals, the Participant shall be credited with a number of Share Units equal to the Deferral. If it becomes necessary to determine the value of a full or partial share Unit prior to any public offering of Company Stock, such value shall be based on the then prevailing Formula Price (as determined under the Company’s Certificate of Incorporation) as of the date the Deferrable Amount would have been paid to the participant but for the Deferral hereunder. Following any public offering of Company Stock, such value shall be determined according to the Fair Market Value of the Company Stock as of the date the Deferrable Amount would have been paid to the Participant but for the Deferral hereunder. However, for Deferrals made by Directors following any public offering of Company Stock, such value shall be determined according to the Fair Market Value of the Company Stock as of the third business day of the calendar quarter following the calendar quarter in which the Deferral Amount was earned by the Director.”

IN WITNESS WHEREOF, the undersigned has adopted this Amendment on the date shown below, but effective as of the dates indicated above.
