                                     PART II

              INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

Item 3. Incorporation of Documents by Reference

        Incorporated by reference in this Registration Statement are the
following documents heretofore filed by Network Solutions, Inc. (the "Company")
with the SEC pursuant to the Securities Exchange Act of 1934, as amended (the
"Exchange Act"):

        (a)     The Company's latest annual report filed pursuant to Section
                13(a) or 15(d) of the Exchange Act;

        (b)     All other reports filed by the Company pursuant to Section 13(a)
                or 15(d) of the Exchange Act since the end of the fiscal year
                covered by the annual report referred to in (a) above; and

        (c)     The description of the Company's Common Stock, par value $0.001
                per share (the "Common Stock"), contained in a registration
                statement filed under the Exchange Act, and any amendment or

        All documents subsequently filed by the Company pursuant to Sections

post-effective amendment that indicates that all securities offered hereby have

Item 4. Description of Securities

        Not applicable.

Item 5. Interests of Named Experts and Counsel

        The validity of the Common Stock will be passed upon for the Company by
Jonathan W. Emery, its General Counsel.

Item 6. Indemnification of Directors and Officers

        The Delaware General Corporation Law (the "Delaware Law") permits a
Delaware corporation to include a provision in its Certificate of Incorporation,
and the Company's Restated Certificate of

<PAGE>   3

Incorporation so provides, eliminating or limiting the personal liability of a
director to the Corporation or its stockholders for monetary damages for breach
of fiduciary duty as a director, provided that such provision may not eliminate
or limit the liability of a director (i) for any such breach of the director's
duty of loyalty to the corporation or its stockholders, (ii) for acts or
omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, or (iii) under Section 174 of the Delaware law which
makes directors personally liable for unlawful dividends or unlawful stock
repurchases or redemptions. Under Delaware law, directors and officers may be
indemnified against expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement in connection with any threatened, pending or
completed action, suit or proceeding whether civil, criminal, administrative or
investigative (other than an action by or in the right of the corporation (a
"derivative action")) if they acted in good faith and in a manner they
reasonably believed to be in or not opposed to the best interest of the
corporation and, with respect to any criminal action or proceeding, had no
reasonable cause to believe their conduct was unlawful. In derivative actions,
indemnification extends only to expenses (including attorneys' fees) incurred
in connection with defense or settlement of such an action and, in the event
such person shall have been adjudged to be liable to the corporation, only to
the extent that a proper court shall have determined that such person is fairly
and reasonably entitled to indemnity for such expenses.

        In addition to the Company's Restated Certificate of Incorporation, the
Company's Bylaws provide that directors and officers shall be, and at the
discretion of the Board of Directors, non-officer employees may be, indemnified
by the Company to the fullest extent authorized by Delaware law, as it now
exists or may in the future be amended, against all expenses and liabilities
reasonably incurred in connection with service for or on behalf of the Company
and further permits the advancing of expenses incurred in defending claims. The
Bylaws also provide that the right of directors and officers to indemnification
shall be a contract right and shall not be exclusive of any other right now
possessed or hereafter acquired under any Bylaw, agreement, vote of stockholders
or otherwise. The Company has contracted separately with its directors and
officers to indemnify such individuals to the extent permitted under law and in
accordance with the Company's Restated Certificate of Incorporation and Bylaws.

        The Company maintains directors' and officers' reimbursement and
liability insurance pursuant to standard form policies. The risks covered by
such policies include certain liabilities under the securities law.

Item 7. Exemption from Registration Claimed

        Not applicable.

Item 8. Exhibits

        An Exhibit Index, containing a list of all exhibits filed with this
Registration Statement, is included on page 9. Additionally, the Registrant
hereby undertakes to (i) submit the Network Solutions, Inc. 401(k) Retirement
Plan (the "Plan") and any amendment thereto to the Internal Revenue Service (the
"IRS") in a timely manner and (ii) make all changes required by the IRS in order
to qualify the Plan under Section 401(a) of the Internal Revenue Code of 1986,
as amended.

Item 9. Undertakings

        (a) Rule 415 Offering. The Company hereby undertakes:

        (1) To file, during any period in which it offers or sells securities, a
    post-effective amendment to this Registration Statement to:

            (i) include any Prospectus required by Section 10(a)(3) of the
        Securities Act, unless the information is contained in periodic reports
        filed by the Company pursuant to section 13 or section 15(d) of the
        Exchange Act that are incorporated by reference in the Registration
        Statement;

<PAGE>   4

            (ii) reflect in the Prospectus any facts or events arising after the
        effective date of the Registration Statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in the Registration Statement, unless the information is contained in
        periodic reports filed by the Registrant pursuant to Section 13 or
        Section 15(d) of the Exchange Act that are incorporated by reference in
        the Registration Statement; or

            (iii) include any material information with respect to the plan of
        distribution not previously disclosed in the Registration Statement or
        any material change to such information in the Registration Statement.

        (2) That, for the purpose of determining any liability under the
    Securities Act, each such post-effective amendment shall be deemed to be a
    new registration statement relating to the securities offered therein, and
    the offering of such securities at that time shall be deemed to be the
    initial bona fide offering thereof.

        (3) To file a post-effective amendment to remove from registration any
    of the securities being registered which remain unsold at the termination of
    the offering.

        (b) Subsequent Exchange Act Documents. The Company hereby undertakes
that, for purposes of determining any liability under the Securities Act, each
filing of the Company's annual report pursuant to section 13(a) or section 15(d)
of the Exchange Act (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to section 15(d) of the Exchange Act) that is
incorporated by reference in the Registration Statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

        (c) Indemnification. Insofar as indemnification for liabilities arising
under the Securities Act may be permitted to directors, officers and controlling
persons of the Company pursuant to the foregoing provisions, or otherwise, the
Company has been advised that in the opinion of the SEC such indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the Company of expenses incurred or paid
by a director, officer or controlling person of the Company in the successful
defense of any action, suit or proceeding) is asserted by such director, officer
or controlling person in connection with the securities being registered, the
Company will, unless in the opinion of its counsel the matter has been settled
by controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.

October 27, 1999

Network Solutions, Inc.
505 Huntmar Park Drive
Herndon, Virginia  20170

Dear Sirs:

As General Counsel for Network Solutions, Inc., a Delaware corporation (the
"Company"), I have participated in the preparation of the registration statement
on Form S-8 (the "Registration Statement") relating to 500,000 shares of the
Company's common stock, par value $.001 per share (the "Common Stock"), to be
issued pursuant to the Network Solutions, Inc. 401(k) Retirement Plan (the
"Plan").

I am familiar with the written document which comprises the Plan, and in
rendering the opinion expressed below, I have examined and am relying on
originals, or copies certified or otherwise identified to my satisfaction, of
such other corporate records, documents, certificates or other instruments, as
in my judgment are necessary or appropriate as a basis for such opinion. In
rendering such opinion, I have noted that the purchase price of the Common Stock
under the Plan with employee elective deferrals will not be less nor greater
than the fair market value of said shares as of the date of purchase by the
Plan's trustee.

Based on the foregoing, I am of the opinion that authorized but previously
unissued shares of Common Stock which may be issued by the Company for purchase
by the Plan have been duly authorized and when purchased in accordance with the
terms of the Plan will be validly issued, fully paid and non-assessable.

I hereby consent to the filing of this opinion as an exhibit to the Company's
Registration Statement. In giving such consent, I do not thereby admit that I am
within the category of persons whose consent is required under Section 7 of the
Act or the rules and regulations of the Securities and Exchange Commission
thereunder.

Very truly yours,

/s/ JONATHAN W. EMERY
Jonathan W. Emery
Senior Vice President, General Counsel

                   pursuant to an unfunded nonqualified plan of deferred
                   compensation are permitted to be considered as Compensation
                   for Code section 415 purposes in the year the amounts are
                   includible in the gross income of the Employee;

          (b)      Amounts realized from the exercise of a nonqualified stock
                   option, or when restricted stock (or property) held by the

                   subject to a substantial risk of forfeiture;

          (c)      Amounts realized from the sale, exchange or other
                   disposition of stock acquired under a qualified or incentive
                   stock option; and

          (d)      Other amounts that received special tax benefits, such as
                   premiums for group-term life insurance (but only to the
                   extent that the premiums are not includible in the gross
                   income of the Employee) or Company Contributions (whether or
                   not under a salary reduction agreement) towards the purchase
                   of an annuity described in Code section 403(b) (whether or
                   not the amounts are actually excludible from the gross
                   income of the Employee).

          Notwithstanding the foregoing, "Compensation" for purposes of this
subsection 2.19 shall include Elective Deferrals under Code section 402(g)(3)
and amounts

contributed under Code section 125, by the Company at the Employee's election

                   402(e)(3) and 402(h)(1)(B) and, in the case of Company
                   Contributions made pursuant to a salary reduction agreement,
                   without regard to Code section 403(b).

          (b)      For purposes of determining the Contribution Percentage and
                   Deferral Percentage of a Participant, "Compensation" shall
                   mean the amount determined above.

          (c)      For purposes of determining the amount that may be deferred
                   as provided in Article V, "Compensation" shall mean the
                   Participant's salary or wages (as otherwise would be
                   reflected in his regular payroll stub before reductions by
                   amounts the Participant elects to defer pursuant to Article
                   V) plus one hundred percent (100%) of any cash sums paid to
                   the Participant (or payable, but for an election by a
                   Participant pursuant to Article V) and exclusive of (i) any
                   stock bonus regardless of whether it was fully vested when
                   awarded and (ii) any taxable assignment allowances paid to
                   any Employee who is on assignment away from normal work
                   location(s) and entitled to receive one or more taxable
                   allowances or adjustments to Compensation based on such
                   assignment.

          (d)      In addition to other applicable limitations set forth in the
                   plan, and notwithstanding any other provision of the plan to
                   the contrary, the annual compensation of each employee taken
                   into account under the plan shall not exceed the OBRA '93
                   annual compensation limit.  The OBRA '93 annual compensation
                   limit is $150,000, as adjusted by the Commissioner for
                   increases in the cost of living in accordance with section
                   401(a)(17)(B) of the Internal Revenue Code.  The
                   cost-of-living adjustment in effect for a calendar year
                   applies to any period, not exceeding 12 months, over which
                   compensation is determined (determination period) beginning
                   in such calendar year.  If a determination period consists
                   of fewer than 12 months, the OBRA '93 annual compensation
                   limit will be multiplied by a fraction, the numerator of
                   which is the number of months in the determination period,
                   and the denominator of which is 12.

          Any reference in this plan to the limitation under section 401(a)(17)
of the Code shall mean the OBRA '93 annual compensation limit set forth in this
provision.

                                   Contribution Percentage of Nonhighly
                                   Compensated Employees; and

                        (B)        The Average Contribution Percentage of
                                   Nonhighly Compensated Employees plus two (2)
                                   percentage points or such lesser amount as
                                   the Secretary of the Treasury shall
                                   prescribe in order to prevent the multiple
                                   use of the alternative limitation with
                                   respect to any Highly Compensated Employee.

                   (ii) If any Highly Compensated Employee is eligible to make
                        elective salary deferrals under a cash or deferred
                        arrangement and to make after-tax Employee
                        contributions or to receive matching contributions
                        under the Plan or any other plan maintained by the
                        Company, the disparity between the Average Contribution
                        Percentage of the Highly Compensated Employee group and
                        the Nonhighly Compensated Employee group shall be
                        reduced as provided in Income Tax Regulations, Section
                        1.401(m)-2.

          (b)      Excess Aggregate Contributions (and income thereon if
                   required by applicable regulations) shall be distributed to
                   the appropriate Highly Compensated Employees (or forfeited,
                   if forfeitable) after the close of the Plan Year in which
                   the Excess Aggregate Contributions arose and in any event
                   within twelve (12) months after the close of such Plan Year.
                   Excess Aggregate Contributions shall be treated as Annual
                   Additions.  In the event of a complete termination of the
                   Plan during a Plan Year in which Excess Aggregate
                   Contributions arose, such distributions shall be made after
                   the date of termination of the Plan and as soon as
                   administratively feasible, but in no event later than the
                   close of the twelve-month period following the date of such
                   termination.  The income

                   allocable to Excess Aggregate Contributions shall be equal
                   to the sum of the allocable gain or loss for the Plan Year
                   and the allocable gain or loss for the period between the
                   end of the Plan Year and the date of distribution.  Income
                   includes all earnings and appreciation, including such items
                   as interest, dividends, rents, royalties, gains from sale of
                   property, appreciation in the value of stocks, bonds,
                   annuity and life insurance contracts, and other property,
                   without regard to whether such appreciation has been
                   realized.  A corrective distribution of Excess Aggregate
                   Contributions (and income thereon if required by applicable
                   regulations) may be made without regard to any notice or
                   consent that otherwise would be required under sections 411
                   and 417 of the Code.

                   The amount of Excess Aggregate Contributions for a Highly
                   Compensated Employee shall be determined as follows: First,
                   the matching contributions of the Highly Compensated
                   Employee with the highest dollar amount of matching
                   contributions is reduced to the extent necessary to satisfy
                   the Average Contribution Percentage test set forth above or
                   to cause such dollar amount of matching contributions of
                   such Highly Compensated Employee to equal the next highest
                   dollar amount of matching contributions for any Highly
                   compensated Employee.  Second, this process is repeated
                   until the Average Contribution Percentage test set forth
                   above is satisfied.  The amount of Excess Aggregate
                   Contributions for a Highly Compensated Employee is then
                   equal to the reduction in matching contributions as
                   determined above.

                   (i)  Forfeitures of Company matching contributions shall be
                        applied in accordance with Section 6.10.

                   (ii) Distributions or forfeitures, as applicable, of Excess
                        Aggregate Contributions shall be made from the
                        Participant's Matching Contribution Account.  No
                        distribution shall be made of Excess Aggregate
                        Contributions to any Highly Compensated Employee as
                        long as any other Highly Compensated Employee has a
                        higher dollar amount of matching contributions.

          (c)           Special Rules.

                   (i)  The Contribution Percentage of a Highly Compensated
                        Employee who is eligible to participate in two or more
                        plans maintained by the Company or an Affiliated
                        Company to which matching contributions, or elective
                        salary deferrals (with respect to the same
                        Compensation) are made shall be aggregated for purposes
                        of determining such Employee's Contribution Percentage.

                                                                   June 25, 1999



                   (ii) If this Plan satisfies the requirements of section
                        410(b) of the Code only if aggregated with one or more
                        other plans or if one or more other plans satisfy the
                        requirements of section 410(b) of the Code only if
                        aggregated with this Plan, then this Section 4.2 shall
                        be applied by determining the Contribution Percentages
                        of Participants as if all such plans were a single
                        plan.  Plans may be aggregated only if they have the
                        same plan year.

          The determination and treatment of the Contribution Percentage of any
Employee shall satisfy any other requirements prescribed by the Secretary of
the Treasury.

          No benefit other than matching contributions shall be conditioned
(directly or indirectly) upon the Employee's election to make or not to make
Elective Deferrals under the Plan.

          4.3      PROFIT SHARING CONTRIBUTIONS.  Profit Sharing Contributions
shall be allocated (based on the Participant's Compensation for the relevant
Plan Year) to those Participants who (a) were employed as of the last day of
the Plan Year for which such contribution is made or whose employment
terminated during such Plan Year due to death, Disability or retirement and (b)
who had completed at least one Year of Service by the last day of such Plan
Year.

          4.4      FORM OF COMPANY CONTRIBUTIONS.  Except as otherwise provided
for in this Article IV, the Company Contributions to the Trust Fund shall be
paid in cash, Company Stock, or such other property as the Board of Directors
may from time to time determine.

          4.5      VALUATION OF COMPANY CONTRIBUTIONS IN THE FORM OF COMPANY
STOCK.  Company Stock contributed by the Company to the Trust Fund shall be
valued using the rules set forth in Section 6.9(a)(ii).

          4.6      RETURN OF COMPANY CONTRIBUTIONS.  The Company shall have no
right or title to, nor interest in, the contributions made to the Trust Fund,
and no part of the Trust Fund shall revert to the Company except that funds may
be returned to the Company as follows:

          (a)      In the case of a Company Contribution which is made by a
                   mistake of fact, that contribution shall be returned to the
                   Company within one (1) year after such contribution is made.

          (b)      All Company Contributions to the Plan are conditioned upon
                   the deductibility of those contributions under Code section
                   404.  To the extent a deduction is disallowed, the
                   contribution shall, at the election of

                   the Company, be returned to the Company within one (1) year
                   after the disallowance.

                                   ARTICLE V
                          ELECTIVE DEFERRALS, ROLLOVER
                    CONTRIBUTIONS AND PLAN-TO-PLAN TRANSFERS

          5.1      ELECTION.  At the time or times established from time to
time by the Committee and subject to the terms and conditions of the Plan, each
Participant may elect, pursuant to such procedures as shall be established by
the Committee from time to time, to defer the receipt of a portion of his
Compensation for that Plan Year and to have the deferred amount contributed
directly by the Company to the Trust Fund as Elective Deferrals.
Notwithstanding the foregoing, no Elective Deferrals shall be taken with
respect to employee referral bonuses or other non-recurring cash payments, made
at the Company's sole discretion, and not forming a significant part of the
Participant's compensation.

          (a)      The Committee may, in its discretion, estimate, as soon as
                   is reasonably possible prior to the close of the Plan Year,
                   the extent (if any) to which deferral treatment under Code
                   section 401(k) may not be available to any Participant (or
                   class of Participants).  If, pursuant to these estimates by
                   the Committee, a Participant (or a class of Participants) is
                   not eligible for deferral treatment for any or all of the
                   amounts deferred pursuant to the election set forth above in
                   Section 5.1, then the Committee may authorize a suspension
                   of Elective Deferrals made pursuant to the provisions of
                   this Article V. This suspension shall be made pursuant to
                   rules promulgated by the Committee.  These rules may include
                   provisions authorizing the suspension of Elective Deferrals
                   above a specified dollar amount of Compensation, or any
                   other means that the Committee believes will help to ensure
                   that deferral treatment will be available for all
                   Participants.

          (b)      A Participant may at any time, pursuant to such procedures
                   as shall be established by the Committee, request that he
                   wishes to terminate, alter the rate of, or resume his
                   Elective Deferrals made pursuant to this Article V.  Any
                   such request for termination, alteration, or resumption
                   shall be effective as soon as practicable after the date
                   made in accordance with the applicable procedures.

          5.2      AMOUNT SUBJECT TO ELECTION.  Subject to the provisions of
Section 5.3, the maximum percentage of an individual's Compensation that may be
deferred subject to the election provided in Section 5.1 shall be eighteen
percent (18%).  For purposes of this Section 5.2, the amount of the
individual's Compensation shall be determined prior to the

                                                                   June 25, 1999


reduction caused by the deferral (if any) of a portion of his Compensation
pursuant to this Article V.

          (a)      The maximum amount of Elective Deferrals contributed on
                   behalf of a Participant under the Plan shall not exceed
                   $7,000 (adjusted by the Adjustment Factor) during any
                   calendar year.  If, during a calendar year, (i) an Employee
                   participates in this Plan and one or more other plans with
                   qualified cash or deferred arrangement described in Code
                   section 401(k), 408(k)(6) or 403(b), (ii) the Employee's
                   Elective Deferrals under all such plans (including this
                   Plan) exceed $7,000 (adjusted by the Adjustment Factor), and
                   (iii) all or any portion of such Employee's Elective
                   Deferrals under this Plan constitute Excess Deferrals by
                   virtue of an allocation and notification by the Employee
                   pursuant to Code section 402(g)(2)(A)(i), such Excess
                   Deferrals shall be distributed to such Employee as permitted
                   by Code section 402(g)(2)(A)(ii).

          5.3      NONDISCRIMINATION REQUIREMENT AND DISTRIBUTION OF EXCESS
CONTRIBUTIONS.    The Committee shall determine if Excess Contributions exist
(which shall be determined after determining Excess Deferrals) by
recharacterizing Elective Deferrals as Excess Contributions to the extent
necessary such that the remaining Elective Deferrals not so recharacterized
satisfy the Average Deferral Percentage test of either paragraph (i) or (ii)
below (together referred to as the "ADP test").

                   (i)       The Average Deferral Percentage of Participants
                             who are Highly Compensated Employees is not more
                             than the Average Deferral Percentage for Nonhighly
                             Compensated Employees multiplied by 1.25; or

                   (ii)      The Average Deferral Percentage of Participants
                             who are Highly Compensated Employees is not more
                             than two hundred percent (200%) of the Average
                             Deferral Percentage of Nonhighly Compensated
                             Employees and is also not more than the Average
                             Deferral Percentage of Nonhighly Compensated
                             Employees plus two (2) percentage points.

          (a)      Excess Contributions for a Highly Compensated Employee shall
                   be determined as follows:

                   (i)  First, the Elective Deferrals of the Highly Compensated
                        Employee with the highest dollar amount of Elective
                        Deferrals is reduced to the extent necessary to satisfy
                        the Average Deferral Percentage (ADP) test set forth in
                        Section 5.3(a) above or to cause such dollar amount of
                        Elective Deferrals to equal the dollar amount of
                        Elective





                                       21

                                                                   June 25, 1999


                        Deferrals of the Highly Compensated Employee with the
                        next highest dollar amount of Elective Deferrals.

                   (ii) Second, this process is repeated until the ADP test is
                        satisfied.  The amount of Excess Contributions for a
                        Highly Compensated Employee is then equal to the
                        reduction in Elective Deferrals made to satisfy the ADP
                        test.

          In determining the Average Deferral Percentage test of this Section
5.3, the Plan will take into account the Deferral Percentage of all eligible
Employees.  For this purpose, an eligible Employee is any Employee who is
directly or indirectly eligible to make a cash or deferred election under the
Plan (i.e., to make Elective Deferrals) for all or a portion of the Plan Year
and includes an Employee who would be a Participant but for the failure to make
Elective Deferrals; an Employee whose eligibility to make Elective Deferrals
has been suspended because of an election not to participate, or to take a
distribution or a loan; and an Employee who cannot make Elective Deferrals
because of the Code section 415 limits on Annual Additions.  In the case of an
eligible Employee who makes no Elective Deferrals, the Deferral Percentage that
is included in the Average Deferral Percentage test is zero.

          (b)      Excess Contributions plus, if required by applicable
                   regulations, any income and minus any loss allocable to such
                   Contributions shall be distributed no later than the last
                   day of each Plan Year to the Highly Compensated Employees to
                   whose Accounts such Excess Contributions were allocated for
                   the preceding Plan Year for which such contributions were
                   allocated.  Excess Contributions shall be treated as Annual
                   Additions.  The income or loss allocable to such
                   Contributions shall include the income or loss for the Plan
                   Year for which the Excess Contributions were made and income
                   or loss for the period between the end of the Plan Year and
                   the date of the distribution.  Such income or loss shall be
                   determined pursuant to procedures established by the
                   Committee consistent with Code section 401(k)(8)(A) and
                   Income Tax Regulations, Section 1.401(k)-1(f)(4).

          (c)      Distribution of Excess Contributions (plus income and minus
                   loss thereon if required by applicable regulations) shall be
                   made on the basis of the respective portions of the Excess
                   Contributions attributable to each Highly Compensated
                   Employee.  Distribution shall be made first from the Plan
                   Accounts of the Highly Compensated Employees whose Elective
                   Deferrals represent the highest dollar amount of Elective
                   Deferrals for the Plan Year.  No distribution shall be made
                   of Excess Contributions to any Highly Compensated Employee
                   as long as any other Highly Compensated Employee has a
                   higher dollar amount of Elective Deferrals.  Any decrease in
                   the amount of Elective Deferrals to be made

                   on behalf of a Participant or a distribution of Excess
                   Contributions under this subsection (c) will also be
                   effective for purposes of determining the amount of
                   Qualified Matching Contributions, if any, to be allocated to
                   such Participant under Section 6.8 below.

          (d)      The Deferral Percentage for any Participant who is a Highly
                   Compensated Employee for the Plan Year and who is eligible
                   to have salary deferrals described in Code section
                   402(g)(3)(A) or qualified nonelective contributions
                   described in Code section 401(m)(4)(C) allocated on his or
                   her behalf under two or more plans or arrangements described
                   in Code section 401(k) that are maintained by the Company or
                   any Affiliated Company shall be determined as if all such
                   deferrals and contributions were made under a single
                   arrangement.

          (e)      The Committee may prescribe such rules as it deems necessary
                   or appropriate regarding the maximum amount that a
                   Participant may elect to defer and the timing of such an
                   election.  These rules may prescribe a maximum percentage of
                   Compensation that may be deferred, or may provide that the
                   maximum percentage of Compensation that a Participant may
                   defer will be a lower percentage of his Compensation above a
                   certain dollar amount of Compensation than the maximum
                   deferral percentage below that dollar amount of
                   Compensation.  These rules shall apply to all individuals
                   eligible to make the election described in Section 5.1,
                   except to the extent that the Committee prescribes special
                   or more stringent rules applicable only to Highly
                   Compensated Employees.

          (f)      Subject to the Company's sole discretion, as an alternative
                   means for complying with the ADP test, the Company may:

                   1.   make Company Qualified Matching Contributions in
                        accordance with Code Section 401(m)(4)(a); or

                   2.   qualified nonelective contributions in accordance with
                        Code Section 401(m)(4)(c).

          5.4      ALTERNATIVE TESTING GROUPS AND METHODS.  In determining
whether the ADP test (under Section 5.3) and/or Average Contribution Percentage
test (under Section 4.2) is or are satisfied, the Committee may elect to test
separately those Employees who would not be eligible to participate if the Plan
imposed a minimum one Year of Service and minimum age twenty-one (21)
requirement for eligibility.

          (a)      In applying the ADP test (under Section 5.3) and Average
                   Contribution Percentage test (under Section 4.2), the Plan
                   shall use the current year testing method for the 1999
                   testing year and subsequent years unless and

                                                                   June 25, 1999


                   until changed by the Committee to the prior year method
                   consistent with procedures prescribed by the Internal
                   Revenue Service pursuant to Code sections 401(k)(3)(A) and
                   401(m)(2)(A).

          5.5      ROLLOVER CONTRIBUTIONS FROM OTHER PLANS.  An Eligible
Employee, regardless of whether he has satisfied the participation requirements
of Section 3.1, may transfer to the Trust Fund a Rollover Contribution pursuant
to procedures approved by the Committee from time to time.  The Committee shall
develop such procedures and may require such information from an Employee
desiring to make such a transfer as it deems necessary or desirable to
determine that the proposed transfer will meet the requirements of a Rollover
Contribution.  Upon approval by the Committee, the amount transferred shall be
deposited in the Trust Fund and shall be credited to a Rollover Account.  Such
Rollover Account shall be one hundred percent (100%) vested in the Employee and
shall be valued in accordance with Section 6.9, but shall not share in Company
Contribution allocations.  Upon termination of employment, the total amount of
the Rollover Account shall be treated as part of the Employee's "Distributable
Benefit" under Section 9.7 and distributed in accordance with Sections 9.1
through 9.7, as applicable.

          Upon such transfer by an Employee who is otherwise eligible to
participate in the Plan but who has not yet completed the participation
requirements of Section 3.1, his Rollover Account shall represent his sole
interest in the Plan until he becomes a Participant.

          5.6      PLAN-TO-PLAN TRANSFERS.  In its sole discretion, the
Committee may authorize (subject to procedures established by the Committee)
the Plan to accept a transfer, from a plan qualified under Code section 401(a),
of a Participant's Account balance under such transferee plan, but only to the
extent such Account balance satisfies each of the following requirements:

          (a)      It is comprised solely of pre-tax contributions and/or
                   earnings; and

          (b)      It is made to this Plan from a plan (other than a plan of
                   maintained by an employer who was a member of the same
                   controlled group of corporation as the Company) under which
                   annuities were not made available to Participants as a form
                   of distribution of their benefits thereunder.  Any such
                   transfer shall be allocated to whichever of the
                   Participant's Account(s) the Committee determines to be
                   appropriate.

          Notwithstanding the foregoing, in connection with the establishment
of the Plan, the Plan shall accept a trust to trust transfer from the
Predecessor Plans, and the amounts transferred from the Predecessor Plan shall
be allocated to the Accounts specified herein.

          To the extent required by Code section 411(d)(6), and pursuant to
procedures established by the Committee, an Account balance transferred
pursuant to this Section 5.6

shall retain optional forms of benefit payments that were applicable to such
Account balance prior to the transfer to the Plan.

                                   ARTICLE VI

          (a)      Profit Sharing Contributions shall be based on the
                   Compensation of all Participants eligible to receive an
                   allocation of such Profit Sharing Contributions pursuant to
                   Section 4.3 and shall be allocated to the Profit Sharing
                   Account.

          (b)      All Company Contributions which constitute Qualified
                   Matching Contributions shall be allocated to Participant's
                   Elective Deferral Accounts within ninety (90) days following
                   their contribution to the Trust.

          (c)      Company matching contributions (i.e., matching contributions
                   which do not constitute Qualified Matching Contributions)
                   shall be allocated to the Matching Contribution Accounts of
                   Participants who have made Elective Deferrals during the
                   Plan Year as follows:

                   (i)  In no event shall any Company matching contribution be
                        allocated with respect to Elective Deferrals in excess
                        of ten percent (10%) of Compensation;

                   (ii) Subject to subsection (i) above, with regard to
                        Elective Deferrals by a Participant, an amount of
                        Company matching contributions equal to fifty percent
                        (50%) of the first six percent (6%) of such Elective
                        Deferrals shall be allocated to that Participant.

          (d)      Company contributions in the form of Additional Company
                   Contributions shall be allocated so as to allow the Plan to
                   satisfy the nondiscrimination test set forth in Code section
                   401(k)(3)(A)(ii) and Section 5.3(a) of the Plan.  Subject to
                   the limitations of Article XIV of this Plan and to the
                   requirements of Code sections 401(k)(3)(A)(ii) and
                   401(k)(3)(C)(ii)(II), Additional Company Contributions shall
                   be allocated as an equal dollar amount to Elective Deferral
                   Accounts of all Eligible Employees who (i) are Nonhighly
                   Compensated Employees, (ii) are employed on the last day of
                   the Plan Year for which such allocation is made and (iii)
                   either already have, or would otherwise have (without regard
                   to an allocation of Additional Company Contributions) for
                   such Plan Year, an Elective Deferral Account established for
                   their benefit.  Such allocation shall be made on or before
                   the due date of the Company's Federal income tax return for
                   the fiscal year with which or within which such Plan Year
                   ends.

          (e)      Company Contributions which constitute Qualified Matching
                   Contributions shall be allocated to the Elective Deferral
                   Accounts of

                   Participants who are Nonhighly Compensated Employees and who
                   have made Elective Deferrals during the Plan Year as
                   follows:

                   (i)  In no event shall any Qualified Matching Contribution
                        be allocated with respect to Elective Deferrals in
                        excess of ten percent (10%) of Compensation;

                   (ii) Subject to subsection (i) above, Qualified Matching
                        Contributions shall be allocated in proportion to the
                        Elective Deferrals of eligible Participants.

          (f)      Company Contributions pursuant to Section 6.11 shall not be
                   allocated to Accounts of Participants but (together with any
                   gains or income thereon) shall be applied to defray Plan
                   expenses.

          (g)      In no event shall amounts be allocated which would cause the
                   limitation on Annual Additions set forth in Article XIV to
                   be exceeded.

          (h)      Company Contributions in the form of Company Stock shall be
                   allocated to the Accounts of the Participants based on the
                   fair market dollar value of such contributed Company Stock
                   as determined under the provisions of Section 6.9(b)(ii),
                   unless a different valuation method shall be required under
                   the applicable Treasury Regulations.

          6.9      VALUATION OF ACCOUNTS.    Within sixty (60) days after each
Valuation Date, within sixty (60) days after the removal or resignation of the
Trustee, and at such other times as determined by the Committee, the Trustee
shall value the assets of the Trust on the basis of fair market values.  If the
assets cannot be valued within any of the periods specified in the preceding
sentence, the assets shall be valued as soon thereafter as is practicable.

          (a)      As soon as is reasonably possible after receipt of these
                   valuations from the Trustee, the Committee shall value the
                   Accounts of each Participant, Suspended Participant and
                   Alternate Payee as of the Applicable Valuation Date so as to
                   reflect the current fair market value of each Account as of
                   such Valuation Date.  The valuation provisions of this
                   Section 6.9 shall be applied and implemented in accordance
                   with the following rules:

                   (i)  If separate subaccounts have been established for
                        separate investment alternatives, each subaccount shall
                        be valued separately and the total value of a
                        Participant's Account(s) shall equal the total value of
                        his interest in each of the respective subaccounts in
                        which his Account(s) have been invested.

                   (ii) Company Stock or SAIC Stock allocated and credited to
                        an account or subaccount, or to a separate fund within
                        the Trust Fund in which Participants' Accounts or
                        subaccounts are invested as provided in Section 8.1,
                        shall be valued as of the Applicable Valuation Date,
                        according to the following rules:

                        (A)  Company Stock acquired by the Trust Fund with cash
                             shall initially be valued at the purchase price
                             paid for such stock.  SAIC Stock transferred to
                             the Plan shall have the value assigned thereto
                             under the applicable Predecessor Plan immediately
                             prior to such transfer.  On any subsequent
                             Valuation Date, such Company Stock or SAIC Stock,
                             shall be valued in accordance with Section
                             6.9(a)(ii)(B) or 6.9(a)(ii)(C) below, as
                             applicable.

                        (B)  If any Company Stock or SAIC Stock does not
                             consist of securities listed on a national
                             securities exchange, or traded on a regular basis,
                             as determined by the Company, in the
                             over-the-counter market, the fair market value of
                             (x) the Company Stock shall be determined by the
                             Committee (or its delegate) and (y) SAIC Stock
                             shall be such value, as determined for purposes of
                             the Predecessor Plan by the committee responsible
                             for the administration thereof, acting in good
                             faith.  A Participant, Beneficiary or Alternate
                             Payee shall have no right to have a particular
                             valuation method applied (or continue to be
                             applied) to his Account(s).

                        (C)  If the Company Stock or SAIC Stock is listed on a
                             national securities exchange, fair market value of
                             such Company Stock or SAIC Stock shall be
                             considered to be equal to the closing price of
                             such Company Stock or SAIC Stock (as reported in
                             the consolidated transaction reporting system, or
                             if not so reported, as reported on the principal
                             exchange on which such Company Stock or SAIC Stock
                             is traded or on any national quotation system over
                             which the Company Stock or SAIC Stock is traded)
                             on the trading day immediately preceding the
                             Applicable Valuation Date.  If any Company Stock
                             or SAIC Stock consists of securities traded on a
                             regular basis, as determined by the Company, in

                   (iii) The fair market value of any guaranteed interest
                         contract, trust or fund holding such a contract, or
                         similar program entered into between an insurance
                         company and the Plan shall be determined based on the
                         principal amount of such contract or program, plus the
                         amount of the guaranteed interest or other increase in
                         value which is paid or credited to the Plan pursuant
                         to such contract or program.  The provisions of this
                         subparagraph (iii) shall apply to an investment
                         alternative established under Section 8.1 which is

                         investment alternative under the Trust, the value of
                         that portion of the Account shall be valued based on

                         company on the Applicable Valuation Date.

          (b)      The Company, the Committee and Trustee do not in any manner
                   or to any extent whatsoever warrant, guarantee or represent
                   that the value of a Participant's Account shall at any time
                   equal or exceed the amount previously contributed thereto,
                   or that any valuation or accounting method or practice will
                   continue to be applied.

          (c)      Allocation of Company Stock or SAIC Stock Received Pursuant
                   to Stock Dividends, Splits, Recapitalizations, Etc.  Any
                   Company Stock or SAIC Stock received by the Trustee as a
                   stock split or dividend, or as a result of a reorganization
                   or other recapitalization of the Company, shall be allocated
                   as of the day on which the stock is received by the Trustee
                   in the same manner as the Company Stock or SAIC Stock to
                   which it is attributable is then allocated.

          (d)      Allocation of Stock Rights, Warrants or Options.

                   (i)    In the event any rights, warrants or options are
                          issued on Company Stock held in the Trust Fund, the
                          Trustee shall exercise them for the acquisition of
                          additional Company Stock as directed by the Committee
                          and to the extent that funds are then available in
                          the Trust Fund.

                   (ii)   Any Company Stock acquired pursuant to subclause (i)
                          shall be treated as Company Stock purchased by the
                          Trustee for the net price paid and shall be allocated
                          in the same manner as the funds used to purchase the
                          Company Stock were or would be allocated under the
                          provisions of this Plan, pursuant to directions of
                          the Committee.

                   (iii)  Any rights, warrants, or options on Company Stock
                          which cannot be exercised for lack of available funds
                          may, as directed by the Committee, be sold by the
                          Trustee and the proceeds allocated in accordance with
                          the source of the Company Stock with respect to which
                          the rights, warrants or options were issued.

          (e)      Allocation of Cash Dividends and Other Distributions
                   Received in the Trust Fund.

                          to Company Stock or SAIC Stock that has been

                          dividend is received by the Trustee shall be
                          allocated to such Account.  If the Company Stock or
                          SAIC Stock in the Trust Fund is held in a Company
                          Stock or SAIC Stock fund as an investment alternative
                          pursuant to Section 8.1, such that Participants have
                          an interest in such Company Stock or SAIC Stock only
                          indirectly through an interest in such fund held in a
                          subaccount, the cash dividends shall be allocated to
                          such fund and shall thereafter be invested in
                          accordance with the investment practices of such
                          fund, and shall not be allocated directly to a
                          Participant's Account or subaccount.

                   (ii)   Other distributions received by the Trustee with
                          respect to investments of the Trust shall be
                          allocated to the applicable fund(s) established
                          pursuant to Article VIII, as prescribed by the
                          Committee.

          6.10     ALLOCATION OF FORFEITURES.  The treatment of all amounts
that are forfeited by reason of the termination of the employment of a

          (a)      Forfeitures shall be used to offset Company matching
                   contributions and profit sharing contributions and allocated
                   to the Matching Contribution Accounts and Profit Sharing
                   Accounts of those Participants who are entitled to receive

                   Year according to the rules of Section 4.1 and 4.3.

          (b)      No forfeitures shall be allocated to any Elective Deferral
                   Account, Profit Sharing Account, Rollover Account, SAIC
                   Stock Account or Alternate Payee Account.

          (c)      The forfeitures to be allocated shall be the amount of
                   forfeitures occurring since the next preceding allocation
                   under this Section 6.10 and prior to the date prescribed by
                   the Committee as the cutoff date for such allocation.

          6.11     COMPANY CONTRIBUTIONS TO DEFRAY PLAN EXPENSES.  The Company

of defraying Plan expenses.  Such contribution shall be used to defray Plan

          6.12     ACCOUNTING PROCEDURES.  The Committee shall establish
accounting procedures for the purpose of making the allocations, valuations and
adjustments to Accounts provided for in this Article VI, as well as the
implementation of investment direction by Participants pursuant to Section 8.1
and transfers between or distributions from subaccounts established pursuant to
Section 8.1(b). From time to time the Committee may modify such accounting
procedures for the purpose of achieving equitable, nondiscriminatory, and
administratively feasible allocations among the Accounts in accordance with the
general concepts of the Plan and the provisions of this Article VI.

          A Participant, Beneficiary or Alternate Payee 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 obligation to any Participant,
Beneficiary or Alternate Payee, consistent with the requirements of Code
section 411(d)(6).

          6.13     SUSPENDED PARTICIPANTS.  The Accounts of each Suspended
Participant shall be held intact and shall be valued on each Valuation Date as
provided in Section 6.9, but shall not receive any allocation of Company
Contributions related to Service while a Suspended Participant.

          6.14     ACCOUNTING FOR INTEREST OF AN ALTERNATE PAYEE.  In the event
an Alternate Payee is awarded an interest in the Plan benefits of a Participant
pursuant to a qualified domestic relations order, as defined in Section 15.2,
such interest shall be separated into one or more separate Accounts and
accounted for under rules prescribed by the Committee, pending distribution to
the Alternate Payee.

interest to, or any right of payment of, any assets of the Trust Fund, except

crediting of any amounts to the Account of a Participant, Beneficiary or
Alternate Payee shall vest in any Participant, Beneficiary or Alternate Payee
any right, title, or interest in or to any assets of the Trust Fund.

          7.2      PARTICIPANT'S VESTED INTEREST - GENERAL RULE.    Subject to
the provisions of Section 7.3, the Vested Interest of each Participant or
Suspended Participant in his Matching Contribution Account, Profit Sharing

</TABLE>

          7.3      VESTED INTEREST - SPECIAL RULES.  The determination of a
Participant's or Suspended Participant's Vested Interest in his Matching
Contribution Account, SAIC Stock Account and Profit Sharing Account shall be
subject to the following special rules:

          (a)      During an Employee's period of employment with the Company
                   or an Affiliated Company (including periods while on an
                   approved leave of absence or a Maternity or Paternity
                   Absence), in the event of his death, Disability, attainment
                   of Normal Retirement Date, or a judicial declaration of his
                   mental incompetence, the Employee's Vested Interest shall be
                   one hundred percent (100%), regardless of his number of
                   Years of Service.

          (b)      A former Employee who is reemployed by the Company or an
                   Affiliated Company, prior to incurring a Period of Severance
                   lasting at least five years shall have his Vested Interest
                   determined as if he had not terminated employment (subject
                   to the provisions of Section 9.5). If a former Employee
                   incurs a Period of Severance lasting at least five years,
                   amounts forfeited from his Matching Contribution Account
                   shall remain forfeited and shall not be restored.

          (c)      If an Employee whose Vested Interest is zero incurs a Period
                   of Severance lasting at least five years, his Years of
                   Service accumulated before such Period of Severance shall
                   not be taken into account for purposes of determining the
                   Vested Interest in his Matching Contribution Account at any
                   time or for any purpose.  An Employee's aggregate Years of
                   Service shall not include any Years of Service not required
                   to be taken into account under this Section 7.3(c) by reason
                   of any prior Period of Severance.

          (d)      No Employee shall be given credit for any Years of Service
                   prior to the date the Employee attained the age of 18.

          (e)      In the event of a divestiture of an operating group or
                   division, the Board of Directors or its delegate may, in its
                   sole discretion, determine, with respect to Eligible
                   Employees whose employment with the Company terminates as a
                   result of such divestiture and in lieu of the otherwise
                   applicable determination of Vested Interest specified in
                   this Article VII, (i) treat the Eligible Employees' Vested
                   Interest as 100%, notwithstanding their Years of Service
                   prior to termination; or (ii) treat such Eligible Employees
                   as Suspended Participants but credit Years of Service with
                   the new employer to whom such group is divested for purposes
                   of determining such Eligible Employees' Vested Interest.
                   Any such determination for a particular group or division
                   shall not bind the Company in any way with respect to any
                   subsequent determination relating to a different group or
                   division.  In the event of a subsequent divestiture from the
                   new employer, the Board of Directors or its delegate may
                   make a similar determination regarding vesting acceleration.

          (f)      In the event the Plan is amended to change any vesting
                   schedule under the Plan, each Participant having no less
                   than three Years of Service shall be permitted to elect,
                   within a reasonable period after the adoption of such
                   amendment, to have his Vested Interest determined under the
                   Plan without regard to such amendment.

          7.4      OTHER ACCOUNTS.  The Vested Interest of each Participant in
his Elective Deferrals Account and Rollover Account (if any) shall at all times
be the entire balance in each such Account.

          7.5      ALTERNATE PAYEE ACCOUNTS.  In the event that an Alternate
Payee is awarded an interest in the Matching Contribution Account of a
Participant whose Vested Interest in such Account is less than 100%, the Vested
Interest at any time of the Alternate Payee in that portion of the Alternate
Payee Account attributable to such awarded interest shall be the same
percentage as the Participant's Vested Interest in his Matching Contribution
Account at that time, determined in accordance with Sections 7.1 through 7.3.

                             INVESTMENT OF ACCOUNTS

          8.1      ELECTIVE DEFERRAL, PROFIT SHARING AND ROLLOVER ACCOUNTS.
The Committee shall establish a choice of investment alternatives from among
which each Participant may elect the manner in which his Elective Deferral
Account (if any), Profit Sharing Account and Rollover Account (if any) will be
invested; provided that in no

event may a Participant elect to invest more than 50% of the contributions to
any such Account in Company Stock or, in connection with a change in the way in
which existing balances in any such Account are invested, direct that more than
50% in the aggregate of the balance then credited to all of the Participant's
Accounts, including, without limitation, his Matching Contributions Account, be
invested in Company Stock.  The Committee shall prescribe procedures for
investment of amounts allocated to an Alternate Payee Account.

          (a)      If such investment alternatives are established, each
                   Participant may elect to invest the assets of his Accounts
                   in such alternatives at such time, in such manner, and
                   subject to such restrictions as the Committee shall specify.

          (b)      Separate funds within the Trust Fund shall be established to
                   reflect the available alternatives, and separate subaccounts
                   shall be established for each investment alternative
                   selected by a Participant, and each such subaccount shall be
                   valued separately.

          (c)      The Committee, in its discretion, may permit Participants to
                   transfer amounts from one investment alternative to one or
                   more other investment alternatives.  An election to transfer
                   such amounts shall be made only at such time, in such
                   manner, and subject to such restrictions as the Committee
                   may specify.  The Committee may provide that future
                   contributions may be invested in a different investment
                   alternative than amounts already accumulated in the
                   Participant's Accounts.

          (d)      The Committee shall prescribe rules relating to the
                   investment of the assets in the Accounts of a Participant
                   who fails to make an effective election, for any reason
                   whatsoever, as to how all or a portion of his Accounts shall
                   be invested.

          (e)      The Committee shall provide notice by arranging for reports
                   to Participants regarding the investment of their funds
                   pursuant to their investment elections.  Failure of a
                   Participant to notify the Committee regarding implementation
                   of his investment election within thirty (30) days following
                   such notice shall be deemed to be an election to have the
                   Accounts invested in the manner shown on such report, even
                   if the manner of investment is different from that specified
                   in the Participant's election form or investment
                   instructions.  If a Participant has not received a notice
                   confirming his investment election (or change therein) and
                   does not notify the Committee or its designated delegate
                   within thirty (30) days of the date such election (or
                   change) was to be effective, the Participant shall be deemed
                   to have elected to have the Accounts invested in the manner
                   in which they are in fact invested, even if that

                                                                   June 25, 1999


                   method differs from the Participant's election form or
                   investment instructions.

          8.2      MATCHING CONTRIBUTION ACCOUNT. Amounts allocated to a
Participant's Matching Contribution Account shall be invested entirely in
Company Stock.

          8.3      SAIC ACCOUNTS.  (a) General Rules.  To the extent that any
portion of any of a Participant's Accounts includes SAIC Stock transferred to
this Plan, such Participant may continue to invest the corresponding portion of
such Account in SAIC Stock until the fourth Quarterly Date.  No additional SAIC
Stock may be acquired.  Any dividends or distributions paid in cash on SAIC
Stock shall be transferred to the Participant's Profit Sharing Account and
invested in proportion to the other investments held in such Profit Sharing
Account.  The cash proceeds from the disposition of any such SAIC Stock or any
dividend or distribution on such SAIC Stock made other than in the form of cash
shall be transferred to the Participant's Profit Sharing Account and invested
in such investment choices as the Participant shall direct (or, absent any such
direction, in the investment option which in the opinion of the Plan
Administrator, involves the least risk of loss of principal).  A Participant
may at any time elect, in accordance with such rules and procedures as the
Committee may establish, to direct the sale of such SAIC Stock on each or any
of the four Quarterly Dates.  All such SAIC Stock not otherwise sold prior to
the fourth Quarterly Date shall be sold and, except as otherwise provided in
Section 8.3(b), the proceeds of any such sale shall be transferred to the
Participant's Profit Sharing Account and invested in the manner described
above.

          (b) Special Rules for Mandatory Transferees.  A Participant who had
an account balance under the SAIC Employee Stock Retirement Plan with a value
in excess of $5,000 immediately prior to the time at which assets are
transferred from such plan to this Plan had the choice not to transfer such
account balance into this Plan, and thereby preserve the right to continue to
invest in SAIC Stock after the fourth Quarterly Date.  A Participant who had an
account balance under the SAIC Employee Stock Retirement Plan with a value of
$5,000 or less immediately prior to the time at which assets are transferred
from such plan to this Plan (a "Mandatory Transferee") did not have such right.
Accordingly, a Mandatory Transferee shall have the right to elect, at the time
that his balance in the SAIC Employee Stock Retirement Plan is to be
transferred to the Plan, to have the cash amount derived from the sale of the
SAIC Stock held in his SAIC Employee Stock Account on the fourth Quarterly Date
retained in such account and thereafter invested in Company Stock.  A Mandatory
Transferee who makes such an election shall not have the right to change the
manner in which such SAIC Employee Stock Account is thereafter invested.  A
Mandatory Transferee who has either SAIC Stock or Company Stock in his SAIC
Employee Stock Account at the date of his termination of employment may elect
to receive a distribution from such Account (and only such Account) in shares
of such Stock, rather than in cash.

          In the event that a Participant receives a distribution from the Plan
consisting in whole or in part of SAIC Stock, such Participant (or the trustee
of any individual retirement account established for the benefit of such
Participant or any Beneficiary of the Participant who has received his or her
rights from the Participant due to the Participant's death or any donee of such
SAIC Stock from the Participant in a bone fide gift) shall have a put option,
having the following terms and conditions:

          (1)      Upon written notice to SAIC and the Company given within the
     sixty-day period following any distribution of such SAIC Stock and stating
     the number of shares of distributed SAIC Stock that the Participant
     intends to sell, the Participant shall have the right to require Science
     Applications International Corporation to purchase all or a portion of
     such distributed SAIC Stock held by such Participant.

          (2)      The purchase price to be paid for any such SAIC Stock shall
     be its fair market value determined as of the Applicable Valuation Date
     determined in accordance with the valuation rules specified in Section
     6.9.  However, in the case of a Participant who is a "disqualified person"
     (within the meaning of Code section 4975(e)(2)), the value of the SAIC
     Stock shall be determined as of the date the Participant gives written
     notice to SAIC of his exercise of the put option under this Section
     8.3(b).

          (3)      If the put option available hereunder is not exercised
     during the initial sixty-day period, the option right shall temporarily
     lapse upon the expiration of such sixty-day period.  As soon as is
     reasonably practicable following the Anniversary Date of the Plan Year in
     which the sixty-day option period expires, SAIC shall notify any person
     who had elected not to exercise such put option of the valuation of SAIC
     Stock as of that Anniversary Date.  During the sixty-day period following
     receipt of such valuation notice, such person shall have the right to
     require SAIC to purchase all or any portion of the distributed SAIC Stock
     that such person then still holds.  The purchase price to be paid therefor
     shall be based on the Anniversary Date valuation of SAIC Stock.  However,
     in the case of a transfer between a Participant who is a "disqualified
     person" (within the meaning of Code section 4975(e)(2)), the value of the
     stock shall be determined as of the date the Participant gives written
     notice to SAIC of his exercise of the put option under this Section
     8.3(b).  If any person fails to exercise his option right under this
     Section 8.3(b) with respect to any portion of the distributed SAIC Stock,
     no further put options shall be applicable under this Plan and SAIC shall
     have no further purchase obligations hereunder.

          (4)      In the event that a put option is exercised under this
     Section 8.3(b), then SAIC shall have the option of paying the purchase
     price of SAIC Stock which is subject to the put option ("Option Stock")
     under either of the following methods:





                                       36

                                                                   June 25, 1999



                   (i)  A lump-sum payment of the purchase price within ninety
          days after the date upon which the put option is exercised ("Exercise
          Date") or

                   (ii) A series of six equal installment payments, with the
          first payment to be made within thirty days following the Exercise
          Date and the five remaining payments to be made on the five
          anniversary dates of the Exercise Date, so that the full amount shall
          be paid as of the fifth anniversary of such Exercise Date.  If SAIC
          elects to pay the purchase price of the Option Stock under the
          installment method provided in this subparagraph (ii), then SAIC
          shall, within thirty days after the Exercise Date, give the person
          who is exercising the put option SAIC's promissory note for the full
          unpaid balance of the option price.  This note shall, at a minimum,
          provide adequate security, state a rate of interest reasonable under
          the circumstances but at least equal to the imputed compound rate in
          effect as of the Exercise Date pursuant to the Treasury Regulations
          promulgated under Code section 483, and provide that the full amount
          of the note shall accelerate and become due immediately in the event
          that SAIC defaults in the payment of a scheduled installment payment.

          (5)      The foregoing put options under this Sections 8.3(b) shall
     be effective solely against SAIC and shall not obligate the Plan or the
     Company in any manner.  Notwithstanding anything else contained in this
     Section 8.3(b) to the contrary, the foregoing put option shall expire and
     be void and without effect at any time that the SAIC Stock is readily
     tradeable on an established securities market.

          (6)      In the event that any person is unable to exercise the put
     option provided hereunder because SAIC is prohibited from honoring it by
     reason of any applicable Federal or State law, then the sixty-day option
     periods during which the put option is exercisable under Sections 8.3(b)
     (1) and (3) shall not include any such time during which the put option
     may not be exercised due to this reason.

          (7)      Except as is expressly provided above with respect to any
     distributed SAIC Stock, no Participant shall have any put option rights
     with respect to SAIC Stock or Company Stock distributed under this Plan,
     and neither SAIC, the Company nor this Plan shall have any obligation
     whatsoever to purchase any distributed SAIC Stock or Company Stock from
     any Participant or any other person.

          (8)      At the time of distribution of SAIC Stock to a Participant
     or Beneficiary, SAIC shall furnish to the Participant or Beneficiary the
     most recent annual certificate of value prepared by SAIC with respect to
     such SAIC Stock.  In addition, SAIC shall furnish to the Participant or
     Beneficiary a copy of each subsequent annual certificate of value until
     the put options provided for in this Section 8.3(b) with respect to the
     distributed SAIC Stock shall expire.

                                   ARTICLE IX
              PAYMENT OF PLAN BENEFITS, IN-SERVICE WITHDRAWALS AND
                           DESIGNATION OF BENEFICIARY

          9.1      RETIREMENT.    A Participant may retire from the employment
of the Company on or after his Normal Retirement Date, consistent with Company
policies.

          (a)      If the Participant continues in the service of the Company
                   beyond his Normal Retirement Date, he shall continue to
                   participate in the Plan in the same manner as Participants
                   who have not reached their Normal Retirement Dates, provided
                   that payment of his Distributable Benefit shall commence no
                   later than his Required Payment Commencement Date.  At the
                   subsequent termination of the Participant's employment, his
                   Distributable Benefit shall be based upon the value of his
                   Accounts as of the Applicable Valuation Date determined with
                   reference to his date of termination of employment as though
                   that were his Normal Retirement Date.

          9.2      METHOD OF DISTRIBUTION UPON RETIREMENT.    Upon retirement a
Participant shall be entitled to a lump-sum distribution of his entire
Distributable Benefit.

          (a)      Payment of the lump-sum distribution shall be made as soon
                   as practicable following the Participant's request made
                   after the Normal Retirement Date provided the Participant
                   consents to any distribution prior to the Participant
                   attaining age 62 and provided further that, in any event,
                   such distribution shall be made no later than the Required
                   Payment Commencement Date.

          9.3      DEATH OR DISABILITY PRIOR TO TERMINATION OF EMPLOYMENT.
Upon the death of a Participant during his employment, or in the event that the
Committee shall determine that a Participant has suffered a Disability while an
Employee of the Company, the Committee shall direct the Trustee to make a
distribution of the Participant's Distributable Benefit to the Participant's
Beneficiary determined under Section 9.8 (in the event of death), or to the
disabled Participant (in the event of Disability).

          (a)      The form of the Distributable Benefit shall be a lump-sum
                   distribution, payable within one hundred twenty (120) days
                   after the close of the Plan Year in which the death of the
                   Participant occurs, or in which he is determined to be
                   Disabled, as the case may be, subject to proof of death or
                   Disability satisfactory to the Committee.

          9.4      DEATH AFTER TERMINATION OF EMPLOYMENT.  Upon the death of a
former Participant after his retirement, Disability or other termination of
employment, but prior to the distribution of his Distributable Benefit to which
he is entitled, the Committee shall

                                                                   June 25, 1999


direct the Trustee to make a distribution of the balance to which the deceased
Participant was entitled, to the Participant's Beneficiary determined under
Section 9.8, such payment to be made within one hundred twenty (120) days after
the close of the Plan Year in which the death of the Participant occurs,
notwithstanding any elections previously made by the Participant.

          9.5      TERMINATION OF EMPLOYMENT PRIOR TO NORMAL RETIREMENT DATE
- -DEFERRED DISTRIBUTION.  Except as otherwise provided in Section 4.3, 9.3 or
9.6, the following rules of this Section 9.5 shall apply in the case of a
Participant whose employment with the Company terminates prior to his Normal
Retirement Date:

          (a)      The Participant's Accounts shall continue to be valued
                   pursuant to Section 6.9, but no further allocations of
                   Company Contributions under Article VI shall be made to such
                   Account, except for an allocation of Company Contributions
                   representing Elective Deferrals made prior to termination
                   and Company matching contributions related thereto.

          (b)      The Participant's Distributable Benefit shall be distributed
                   to him in a lump-sum distribution not later than one hundred
                   twenty (120) days after the Participant requests such
                   distribution pursuant to rules prescribed by the Committee,
                   except as provided in Section 9.5(e) or 9.6, but in any
                   event not later than the Required Payment Commencement Date.

          (c)      In the case of a distribution described in Section 9.5(b),
                   the nonvested portion of the Participant's Matching
                   Contribution Account, Profit Sharing Account and SAIC Stock
                   Account shall be forfeited as of the time of distribution.

          (d)      If the Participant is reemployed by the Company or an
                   Affiliated Company on (or before) incurring a Period of
                   Severance lasting at least five years, then:

                   (i)  If no distribution of his Distributable Benefit
                        following his termination of employment had occurred,
                        no forfeiture shall occur upon such reemployment; and

                   (ii) If a distribution of his Distributable Benefit had
                        previously been made following his termination of
                        employment (along with a forfeiture of the nonvested
                        portion of his Plan Account pursuant to Section
                        9.5(c)), then the Participant shall have the repayment
                        restoration right set forth in Sections 9.6(a)(ii) and
                        (iii).

          (e)      Distribution of benefits under Section 9.5(b) to a
                   Participant whose Distributable Benefit exceeds (or at the
                   time of any prior distribution

                                                                   June 25, 1999


                   exceeded) $5,000 may be made prior to age 62 only with the
                   consent of the Participant.

          (f)      In lieu of receiving his entire Distributable Benefit in a
                   single lump-sum distribution as provided in this Section
                   9.5, a Participant on or after attaining age 59-1/2 may
                   elect to receive a distribution of that portion of his
                   Account(s) that is not invested in Company Stock within the
                   Trust, while leaving in the Plan the remaining portion which
                   is invested in the Company Stock until a later distribution
                   prior to the Required Payment Commencement Date.  Any such
                   partial withdrawal shall be subject to such limitations and
                   restrictions as may be imposed by Committee rule.

          9.6      TERMINATION OF EMPLOYMENT PRIOR TO NORMAL RETIREMENT DATE
- -IMMEDIATE DISTRIBUTION.    A Participant whose employment with the Company
terminates prior to his Normal Retirement Date shall have his Distributable
Benefit, if any, paid to him within twelve months of the date of his
termination of his employment if:

                   (i)  The Distributable Benefit, if any, is $5,000 or less. A
                        Distributable Benefit of zero shall be deemed to result
                        in a distribution of zero.; or

                   (ii) He so elects (pursuant to rules prescribed by the
                        Committee).

          (a)      In the above-described cases, the following rules shall
                   apply:

                   (i)  The nonvested portion of his Matching Contribution
                        Account, Profit Sharing Account, SAIC Matching Account
                        and SAIC Employer Stock Account shall be forfeited as
                        of the date that his Vested Interest is distributed to
                        him.  In the case of a Participant with no Vested
                        Interest in his Matching Contribution Account, Profit
                        Sharing Account, SAIC Matching Account or SAIC Employer
                        Stock Account, the forfeiture shall occur within the
                        period commencing on the date of his termination of
                        employment and ending ninety (90) days following the
                        end of the Plan Year in which his termination of
                        employment occurs.

                   (ii) If the Participant is reemployed by the Company or an
                        Affiliated Company prior to incurring a Period of
                        Severance lasting at least five years, the Participant
                        shall be entitled to have the entire portion of his
                        Matching Contribution Account, Profit Sharing Account,
                        SAIC Matching Account and SAIC Employer Stock Account
                        (including the nonvested portion thereof) reinstated by
                        repaying the total amount distributed to him.  Such
                        reinstatement shall be made from current forfeitures
                        or, if necessary, from Company

                        Contributions and shall not be treated as an Annual
                        Addition.  However, this repayment must be made prior
                        to the earlier of (1) five years from the date of
                        reemployment or (2) the occurrence of a Period of
                        Severance lasting at least five years which commences
                        after the distribution of the Vested Interest in his
                        Plan Account following such termination of employment,
                        provided he is an Eligible Employee during that period.
                        If such repayment is not made, then the previously
                        forfeited amounts shall not be restored to the
                        Participant's Matching Contribution Account, Profit
                        Sharing Account, SAIC Matching Account and SAIC
                        Employer Stock Account.

                  (iii) In the case of a repayment made pursuant to the rules
                        of Section 9.6(a)(ii) above:

                        (A)  The Participant shall not be required to pay any
                             interest charge upon the amounts repaid by him;
                             and

                        (B)  The nonvested portion of his Matching Contribution
                             Account, Profit Sharing Account, SAIC Matching
                             Account and SAIC Employer Stock Account (which was
                             not distributed to him) shall not be adjusted for
                             gains or losses during the period between the
                             forfeiture and the repayment of the distributed
                             amount.

                  (iv)  In the case of a Participant with no Vested Interest in
                        his Matching Contribution Account, Profit Sharing
                        Account, SAIC Matching Account or SAIC Employer Stock
                        Account, who is reemployed prior to incurring a Period
                        of Severance lasting at least five years, the entire
                        nonvested portion of such Accounts (unadjusted for
                        gains or losses during the period between the date of
                        his forfeiture and the date of his reemployment) shall
                        be reinstated upon his reemployment, without regard to
                        the repayment requirement of subsection (iii) above.

                  (v)   In no event shall a Participant who has received a
                        distribution which includes the balance in his Accounts
                        and/or Rollover Account be entitled either to repay the
                        Plan or to have the balance in such Accounts or
                        Rollover Account reinstated upon reemployment by the
                        Company or an Affiliated Company.  However, if the
                        previous distribution otherwise qualifies for a
                        Rollover Contribution, the Participant may make a
                        Rollover Contribution upon reemployment.

          9.7      DISTRIBUTABLE BENEFIT; IN-SERVICE WITHDRAWALS.    A
Participant's "Distributable Benefit" shall be distributable in the form of
cash or, if elected in accordance with Section 9.12, by trustee-to-trustee
transfer.

          (a)      For purposes of determining the amount of Distributable
                   Benefit that will be distributed to a Participant or
                   Beneficiary pursuant to the rules of this Article IX, the
                   value of the Participant's Account shall be determined in
                   accordance with rules prescribed by the Committee.  However,
                   the value of the Participant's Account shall be increased or
                   decreased (as appropriate) by any contributions or
                   distributions properly allocable under the terms of this
                   Plan to his Account that occurred on or after the Applicable
                   Valuation Date or for any other reason were not otherwise
                   properly reflected in the valuation of his Account on such
                   Valuation Date.

          (b)      Neither the Committee, the Company, nor the Trustee shall
                   have any responsibility for any increase or decrease in the
                   value of a Participant's Account as a result of any
                   valuation made under the terms of this Plan after the date
                   of his termination of employment and before the date of the
                   distribution of his Account to him or his Beneficiary.
                   Also, neither the Committee, the Company, nor the Trustee
                   shall have any responsibility for failing to make any
                   interim valuation of a Participant's Account between the
                   date of distribution to the Participant of his Account and
                   the immediately preceding Valuation Date, even though the
                   Plan Assets may have been revalued in that interim for a
                   purpose other than to revalue the Accounts under this Plan.

          (c)      Additionally, a Participant shall be entitled to make
                   withdrawals from his Accounts after the date on which he
                   attains the age of 59-1/2 even though his employment with
                   the Company has not yet been terminated.  Further, a
                   Participant may withdraw amounts from his Elective Deferral
                   Account (and, if his Matching Contribution Account is 100%
                   vested, from his Matching Contribution Account) prior to
                   attaining age 59-1/2, upon incurring a hardship as
                   determined by the Committee, provided that no amount
                   representing earnings on amounts credited to the
                   Participant's Elective Deferral Account (including, without
                   limitation, in respect of a Predecessor Plan after December
                   31, 1988) may be withdrawn.  Any withdrawal permitted under
                   the second sentence of this Section 9.7(c) shall first be
                   made from the Participant's Matching Contributions Account,
                   until all available funds such Account are exhausted.  A
                   withdrawal will be deemed on account of hardship only if the
                   distribution is made on account of an immediate and heavy
                   financial need and is necessary to satisfy such financial
                   need.  Any withdrawal made pursuant to this subparagraph (c)
                   shall be made in accordance with

                                                                June 25, 1999
                   rules prescribed by the Committee that are consistent with
                   Regulations under Code section 401(k), and the following
                   rules:

                   (i)  The determination of whether a Participant has an
                        immediate and heavy financial need is to be made by the
                        Committee on the basis of all relevant facts and
                        circumstances.  A distribution will be deemed to be
                        made on account of an immediate and heavy financial
                        need of the Participant if the distribution is on
                        account of:

                        (A)  Medical expenses (as described in Code section
                             213(d)) of the Participant and his dependent(s)
                             (as defined in Code section 152) not covered by
                             insurance;

                        (B)  Purchase of the principal residence for the
                             Participant;

                        (C)  Payment of tuition and related education fees for
                             the next twelve months of post-secondary education
                             for the Participant or the Participant's spouse,
                             children or dependents (as defined in Code section
                             152); or

                        (D)  The need to prevent the eviction from the
                             Participant's principal residence or foreclosure
                             on the mortgage of the Participant's principal
                             residence.

                   (ii) To receive a hardship withdrawal, the following
                        requirements must first be met by the Participant:

                        (A)  The Participant must sign the appropriate forms
                             and certify all information requested on that
                             form;

                        (B)  The Participant must have withdrawn, or must
                             withdraw at the same time that an application for
                             hardship withdrawal is submitted, all post-tax
                             contributions made under all other Company
                             retirement plans;

                        (C)  The Participant must have applied for all eligible
                             loans from those Company retirement plans which
                             permit Participant loans;

                        (D)  The hardship withdrawal normally cannot be less
                             than $500.00;

                        (E)  The Participant must suspend all Elective
                             Deferrals for twelve (12) months after receiving
                             the hardship withdrawal pursuant to rules
                             prescribed by the Committee; and

                                                                   June 25, 1999



                         (F) The maximum amount of Elective Deferrals for the
                             calendar year following the year of the hardship
                             withdrawal will be the maximum amount permitted by
                             Code section 402(g) for such calendar year less
                             the amount of any Elective Deferrals made by the
                             Participant during the calendar year in which such
                             hardship withdrawal is made.

                   (iii) In the event that a Participant has elected to have
                         his Elective Deferral Account invested in more than
                         one investment alternative pursuant to the rules of
                         Section 8.1, then the withdrawal shall be made pro
                         rata from the subaccounts in which his Account is
                         invested.

                   (iv)  The timing of the payment of the withdrawal shall be
                         made as soon as practicable following the request in
                         accordance with the rules established by the
                         Committee.

          (d)      A Participant's Distributable Benefit from his Rollover
                   Account, if any, shall be distributed in the same fashion as
                   provided in subsection 9.5(a)-(e), 9.6(a)-(b) or 9.7(a)-(d),
                   as applicable.

          9.8      DESIGNATION OF BENEFICIARY.    Subject to the provisions of
Section 9.8(e), each Participant shall have the right to designate a
Beneficiary or Beneficiaries to receive his Distributable Benefit in the Trust
Fund in the event of his death before receipt of his entire interest in the
Trust Fund.  This designation is to be made on the form prescribed by and
delivered to the Committee or its delegate.

          (a)      Subject to the provisions of Section 9.8(e), a Participant
                   shall have the right to change or revoke any such
                   designation by filing a new designation or notice of
                   revocation with the Committee or its delegate.  Subject to
                   the provisions of Section 9.8(e), no notice to any
                   Beneficiary nor consent by any Beneficiary shall be required
                   to effect any such change or revocation.

          (b)      If a deceased Participant shall have failed to designate a
                   Beneficiary, if the Committee shall be unable to locate a
                   designated Beneficiary after reasonable efforts have been
                   made, if for any reason the designation shall be legally
                   ineffective, or if the Beneficiary shall have predeceased
                   the Participant (and no legally effective contingent
                   Beneficiary shall have been named), any distribution
                   required to be made under the provisions of this Plan shall
                   be payable to the Participant's estate (except as provided
                   in Section 9.8(e)), and the estate shall be considered the
                   Beneficiary under this Plan.

                                                                   June 25, 1999



          (c)      In the event that the deceased Participant was not a
                   resident of Virginia at the date of his death, the
                   Committee, in its discretion, may require the establishment
                   of ancillary administration in Virginia.  In the event that
                   a Participant shall predecease his Beneficiary and on the
                   subsequent death of the Beneficiary a remaining distribution
                   is payable under the applicable provisions of this Plan, the
                   distribution shall be payable to the Beneficiary's estate.

          (d)      If a Participant is married at the time of his death, the
                   designation by the Participant under Section 9.8 of a person
                   other than the current Spouse as his Beneficiary shall not
                   take effect (and the entire Distributable Benefit shall be
                   paid to such Spouse) (i) unless the Spouse of the
                   Participant consents in writing to such designation, and the
                   Spouse's consent acknowledges the effect of such designation
                   and is witnessed by a notary, or (ii) unless it is
                   established to the satisfaction of the Committee that such
                   consent is not required because there is no Spouse, because
                   the Spouse cannot be located, or because of such other
                   circumstances as the Secretary of the Treasury may by
                   regulations prescribe.

          (e)      The Company, the Committee and the Trustee shall have no
                   duty to determine whether a Beneficiary designation or
                   spousal consent made-pursuant to this Section 9.8 was an
                   informed designation or consent or was freely given, and
                   shall be entitled to rely upon the Beneficiary designation
                   filed with the Committee or its delegate, as well as such
                   other documents as may be required pursuant to Section 9.11,
                   and shall be under no duty or obligation to protect the
                   rights of a spouse or former spouse of a Participant, except
                   as may be required by law.

          9.9      FACILITY OF PAYMENT.  If any payee under the Plan is a minor
or if the Committee reasonably believes that any payee is legally incapable of
giving a valid receipt and discharge for any payment due him, the Committee may
have the payment, or any part thereof, made to the person (or persons or
institution) whom it reasonably believes is caring for or supporting the payee,
unless it has received due notice of claim therefor from a duly appointed
guardian or committee of the payee.  Any payment shall be a payment from the
Accounts of the payee and shall, to the extent thereof, be a complete discharge
of any liability under the Plan to the payee.

          9.10     DISTRIBUTION TO ALTERNATE PAYEES.  If an Alternate Payee is
entitled to a distribution of benefits from this Plan pursuant to a qualified
domestic relations order, as defined in Section 15.2, the benefits payable to
such Alternate Payee shall be distributed pursuant to such qualified domestic
relations order under rules or procedures described by the Committee. If
permitted by applicable law and regulations, the Committee may require or permit
immediate distribution of such benefits to an Alternate Payee at any time
following the determination by the Committee that such an order is a qualified

domestic relations order.  In the event that an Alternate Payee dies prior to
receipt of the amounts due him from an Alternate Payee Account, such amounts
shall be distributed to the estate of the Alternate Payee as soon as practicable
following the date such amounts would have been distributed to such Alternate
Payee.

          9.11     ADDITIONAL DOCUMENTS.    The Committee or Trustee, or both,
may require (and rely upon) the execution and delivery of such documents,
papers and receipts as the Committee or Trustee may determine necessary or
appropriate in order to establish the fact of death of the deceased Participant
and of the right and identity of any Beneficiary or other person or persons
claiming any benefits under this Article IX.

          (a)      The Committee or the Trustee, or both, may, as a condition
                   precedent to the payment of death benefits hereunder,
                   require an inheritance tax release and/or such security as
                   the Committee or Trustee, or both, may deem appropriate as
                   protection against possible liability for State or Federal
                   death taxes attributable to any death benefits.

          9.12     DIRECT ROLLOVERS.    Notwithstanding any provision of the
Plan to the contrary that would otherwise limit a distributee's election under
this Section 9.12, a distributee may elect, at the time and in the manner
prescribed by the Committee, to have any portion of an eligible rollover
distribution made payable directly to an eligible retirement plan specified by
the distributee in a direct rollover.

                   (i)  Eligible Rollover Distribution.  An eligible rollover
                        distribution is any distribution of all or any portion
                        of the balance to the credit of the distributee, except
                        that an eligible rollover distribution does not
                        include: any distribution that is one of a series of
                        substantially equal periodic payments (not less
                        frequently than annually) made for the life (or life
                        expectancy) of the distributee or the joint lives (or
                        joint life expectancies) of the distributee and the
                        distributee's designated Beneficiary, or for a
                        specified period of 10 years or more; any distribution
                        to the extent such distribution is required under Code
                        section 401(a)(9); and the portion of any distribution
                        that is not includible in gross income (determined
                        without regard to the exclusion for net unrealized
                        appreciation with respect to employer securities).

                   (ii) Eligible Retirement Plan.  An eligible retirement plan
                        is a retirement plan that accepts the distributee's
                        eligible rollover distribution and is an individual
                        retirement account described in Code section 408(a), an
                        individual retirement annuity described in Code section
                        408(b), an annuity plan described in Code section
                        403(a), or a qualified trust described in Code section
                        401(a).  However in the case of an eligible rollover
                        distribution to the surviving spouse, an eligible
                        retirement

                         plan is an individual retirement account or individual
                         retirement annuity.

                   (iii) Distributee.  A distributee includes an Employee or
                         former Employee.  In addition, the Employee's or
                         former Employee's surviving spouse and the Employee's
                         or former Employee's spouse or former spouse who is
                         the Alternative Payee are distributees with regard to
                         the interest of the spouse or former spouse.

                   (iv)  Direct rollover.  A direct rollover is a payment by
                         the Plan to the eligible retirement plan specified by
                         the distributee.

                   Investment Manager appointed pursuant to Section 10.3 shall
                   be named fiduciaries of this Plan.

          10.2     COMMITTEE POWERS.  The Committee shall have all powers
necessary to supervise the administration of the Plan and control its

                   preceding provisions of this Section 10.2(a) shall not limit
                   the authority of the Committee to appoint one or more

                   provisions of this Plan, including one or more persons to
                   render advice with regard to any responsibility any named
                   fiduciary or any other fiduciary may have under the Plan.

          (d)      To establish rules and regulations from time to time for the
                   conduct of the Committee's business and the administration
                   and effectuation of this Plan.

                   any employee, Participant, former Participant, Beneficiary,
                   Alternate Payee or other person whatsoever, including but
                   not limited to all questions relating to eligibility to
                   participate in the Plan, the amount of service of any
                   Participant, and the amount of benefits to which any

                   to purchase, exchange, or lease any property, real or
                   personal, which the Committee may designate.  This shall
                   include the right to direct the investment of all or any
                   part of the Trust in any one security or any one type of
                   securities permitted hereunder.  Among the securities which

                   "employer securities" as defined in Code section 409(1) or
                   any successor statute thereto.

                   Participants may select from in determining investment of
                   their Accounts, and to establish rules and procedures

                   bonding and reporting and disclosure requirements.

          (j)      To perform or cause to be performed such further acts as it
                   may deem to be necessary, appropriate or convenient in the
                   efficient administration of the Plan.

          Any action taken in good faith by the Committee in the exercise of
authority conferred upon it by this Plan shall be conclusive and binding upon
the Participants and their Beneficiaries and any Alternate Payees.  All
discretionary powers conferred upon the Committee shall be absolute, but shall
be exercised in a uniform and nondiscriminatory manner.

          10.3     INVESTMENT MANAGER.    The Committee, by action reflected in
the minutes thereof, may appoint one or more Investment Managers, as defined in
Section 3(38) of ERISA, to manage all or a portion of the assets of the Plan.

          (a)      An Investment Manager shall discharge its duties in
                   accordance with applicable law and in particular in
                   accordance with Section 404(a)(1) of ERISA.

          (b)      An Investment Manager, when appointed, shall have full power
                   to manage the assets of the Plan for which it has
                   responsibility, and neither the Company nor the Committee
                   shall thereafter have any responsibility for the management
                   of those assets, except to the extent such power or
                   responsibility shall have been reserved to the Company or
                   Committee in the documents governing the relationship
                   between or among the Plan, the Company and the Investment
                   Manager.

          10.4     PERIODIC REVIEW.  At periodic intervals, not less frequently
than annually, the Committee shall review the long-run and short-run financial
needs of the Plan and shall determine a funding policy for the Plan consistent
with the objectives of the Plan and the minimum funding standards of ERISA, if
applicable.  In determining the funding policy the Committee shall take into
account, at a minimum, not only the long-term investment objectives of the
Trust Fund consistent with the prudent management of the assets thereof, but
also the short-run needs of the Plan to pay benefits.

          (a)      All actions taken by the Committee with respect to the
                   funding policy of the Plan, including the reasons therefor,
                   shall be fully reflected in the minutes of the Committee.

          10.5     COMMITTEE PROCEDURE.  A majority of the members of the
Committee as constituted at any time shall constitute a quorum, and any action
by a majority of the

                   authorized to execute any document or documents on behalf of
                   the Committee, in which event the Committee shall notify the
                   Trustee of this action and the name or names of the
                   designated members.  The Trustee, Company, Participants,
                   Beneficiaries, and any other party dealing with the
                   Committee may accept and rely upon any document executed by
                   the designated members as representing action by the
                   Committee until the Committee shall file with the Trustee a
                   written revocation of the authorization of the designated
                   members.

          10.6     COMPENSATION OF COMMITTEE.  Members of the Committee shall

Employee receive compensation from the Plan for his services as a member of the
Committee.

                   appropriate expenditures incurred in the discharge of duties
                   as members of the Committee.

          (b)      The compensation or fees, as the case may be, of all
                   officers, agents, counsel, the Trustee, or other persons
                   retained or employed by the Committee shall be fixed by the
                   Committee.

                   status as a member of the Committee, the member's status as
                   a named fiduciary shall concurrently be terminated, and upon
                   the appointment of a successor Committee member the
                   successor shall assume the status of a named fiduciary as
                   provided in Section 10.1.

          10.9     RECORDS.  The Committee shall keep a record of all its
proceedings and shall keep, or cause to be kept, all such books, accounts,
records or other data as may be necessary or advisable in its judgment for the
administration of the Plan and to properly reflect the affairs thereof.

          10.10    RELIANCE UPON DOCUMENTS AND OPINIONS.    The members of the
Committee, the Board of Directors, the Company and any Employee of the Company
delegated under the provisions hereof to carry out any fiduciary responsible
under the Plan ("Delegated Fiduciary"), shall be entitled to rely upon any
tables, valuations, computations, estimates, certificates and reports furnished
by any consultant, or firm or corporation which employs one or more
consultants, upon any opinions furnished by legal counsel, and upon any reports
furnished by the Trustee.  The members of the Committee, the Board of
Directors, the Company and any Delegated Fiduciary shall not be liable in any
manner whatsoever for anything done or action taken or suffered in reliance
from any such consultant or firm or corporation which employs one or more
consultants, trustee, or counsel.

          (a)      Any and all such things done or actions taken or suffered by
                   the Committee, the Board of Directors, the Company and any
                   Delegated Fiduciary shall be conclusive and binding on all
                   Employees, Participants, Beneficiaries, Alternate Payees and
                   any other persons whomsoever, except as otherwise provided
                   by law.

          (b)      The Committee and any Delegated Fiduciary may, but are not
                   required to, rely upon all records of the Company with
                   respect to any matter or thing whatsoever, and may likewise
                   treat those records as conclusive with respect to all
                   Employees, Participants, Beneficiaries, and any other
                   persons whomsoever, except as otherwise provided by law.

          10.11    REQUIREMENT OF PROOF.  The Committee or the Company may, in
its (or their) sole discretion, require satisfactory proof of any matter under
this Plan from or with respect to any Employee, Participant, Beneficiary or
Alternate Payee and no benefits under this Plan need be paid until the required
proof shall be furnished.

          10.12    MULTIPLE FIDUCIARY CAPACITY.  Any person or group of persons
may serve in more than one fiduciary capacity with respect to the Plan.

          10.13    LIMITATION ON LIABILITY.  Except as provided in Part 4 of
Title I of ERISA, neither the Company, the Board of Directors (or any member
thereof), nor the Committee (or any member thereof) shall be subject to any
liability with respect to his duties under the Plan unless he or it acts
fraudulently or in bad faith.

          (a)      Neither the Company, the Board of Directors (or any member
                   thereof) nor the Committee (or any member thereof) shall be
                   liable for any breach

                                                                   June 25, 1999


                   of fiduciary responsibility resulting from the act or
                   omission of any other fiduciary or any person to whom
                   fiduciary responsibilities have been allocated or delegated,
                   except as provided in Part 4 of Title I of ERISA.

          (b)      Neither the Comapny, the Board of Directors (or any member
                   thereof), the Committee (or any member thereof), nor the
                   Trustee shall be liable to the extent relief from liability
                   is provided pursuant to Section 404(c) of ERISA.

          (c)      This Plan document is not intended to create additional
                   fiduciary liability, or to characterize actions or
                   responsibilities as fiduciary in nature, beyond that
                   required by ERISA or other applicable law.

          10.14    INDEMNIFICATION.  To the extent permitted by law, the
Company hereby indemnifies each member of the Board of Directors and the
Committee, and any other Employee of the Company with duties under the Plan,
against expenses (including any amount paid in settlement) reasonably incurred
by him in connection with any claims against him by reason of his conduct in
the performance of his duties under the Plan, except in relation to matters as
to which he acted fraudulently or in bad faith in the performance of such
duties.  The preceding right of indemnification shall pass to the estate of
such a person.

          (a)      The preceding right of indemnification shall be in addition
                   to any other right to which the Board of Directors or
                   Committee member or other person may be entitled as a matter
                   of law or otherwise.

          10.15    ALLOCATION OF FIDUCIARY RESPONSIBILITY.  Section 405(c) of
ERISA permits the division, allocation and delegation among Plan fiduciaries of
the fiduciary responsibilities owed to the Plan Participants and Beneficiaries.
Under this concept, each fiduciary, including a named Fiduciary, is accountable
only for its own functions, except to the extent of his co-fiduciary liability
under Section 405 of ERISA.  It is the intent of the Company in establishing
this Plan to comply with Section 405(c) and to have the limitation on liability
set forth in Section 405(c)(2) of ERISA apply to the maximum extent allowed by
law.

          (a)      Pursuant to Section 405(c) of ERISA, the authority to

                   the Committee include:

                   (i)  Responsibilities identified as Committee authority and

          (a)      The Committee shall not cause the Plan to engage in any
                   transaction that constitutes a nonexempt Prohibited
                   Transaction under Code section 4975(c) or section 406(a) of
                   ERISA.

          (b)      All individuals who are fiduciaries with respect to the Plan
                   (as defined in Section 3(21) of ERISA) shall discharge their
                   fiduciary duties in accordance with applicable law, and in
                   particular, in accordance with the standards of conduct
                   contained in Section 404 of ERISA.

          10.17    BONDING AND INSURANCE.  Except as provided in Section 412 of
ERISA, as may be required under any other applicable law, or as may be required
by the Committee in its sole discretion, no bond or other security shall be

Plan.

          (a)      For purposes of satisfying its indemnity obligations under
                   Section 10.14, the Company may (but need not) purchase and
                   pay premiums for one or more policies of insurance.
                   However, this insurance shall not release the Company of its
                   liability under the indemnification provisions.

          10.18    VOTING AND OTHER RIGHTS OF COMPANY STOCK AND SAIC STOCK.
All voting rights of Company Stock and SAIC Stock held in the Trust Fund shall
be exercised in accordance with the following provisions:

          (a)      Each Participant (which term shall include, for purposes of
                   this Section 10.18, Beneficiaries and Alternate Payees
                   having an interest in an Account or fund holding Company
                   Stock or SAIC Stock) shall be given the opportunity to
                   instruct the Trustee confidentially on a form (or in such
                   other manner as is) prescribed and provided by the Company
                   or Science Applications International Corporation, as
                   applicable, as to how to vote those shares (including
                   fractional shares) of Company Stock and SAIC Stock allocated
                   to his Account(s) under the Plan (directly or indirectly
                   through an interest in a Company Stock or SAIC Stock fund)
                   on the date immediately preceding the record date for the
                   corresponding meeting of shareholders.  The Trustee shall
                   not divulge to the Company or Science Applications
                   International Corporation, as the case may be, the
                   instructions of any Participant.  The Company may require
                   verification of the Trustee's compliance with such
                   confidential voting instructions by an independent auditor
                   elected by the Company or Science Applications International
                   Corporation, as the case may be.

                   (i)  All Participants entitled to direct such voting shall
                        be notified by the Committee (or the Company or Science
                        Applications International Corporation, as the case may
                        be, pursuant to its normal communications with
                        shareholders) of each occasion for the exercise of
                        these voting rights within a reasonable time (but not
                        less than the

                                                              June 25, 1999
                         time period that may be required by any applicable
                         state or federal law) before these rights are to be
                         exercised.  The notification shall include all
                         information distributed to other shareholders
                         regarding the exercise of such rights.

                   (ii)  The Participants shall be so entitled to direct the
                         voting of fractional shares (or fractional rights to
                         shares).  However, the Committee may, to the extent
                         possible, direct the Trustee to vote the combined
                         fractional shares (or fractional rights to shares) so
                         as to reflect the aggregate direction of all
                         Participants giving directions with respect to
                         fractional shares (or fractional rights to shares).

                   (iii) In the event that a Participant shall fail to direct
                         the Trustee, in whole or in part, as to the exercise
                         of voting rights arising under any Company Stock or
                         SAIC Stock allocated to his Account, then these voting
                         rights, together with voting rights as to shares, if
                         any, of Company Stock or SAIC Stock which have not
                         been allocated, shall be exercised by the Trustee in
                         the same proportion as the number of shares of Company
                         Stock or SAIC Stock for which the Trustee has received
                         direction in such matter (e.g., to vote for, against
                         or abstain from voting on a proposal, or to grant or
                         withhold authority to vote for a director or
                         directors), and the Trustee shall have no discretion
                         in such matter, except as may be required by
                         applicable law.

                   (iv)  Except as provided in paragraph (b) below, all rights
                         (other than voting rights) of Company Stock or SAIC
                         Stock held in the Trust Fund shall be exercised in the
                         same manner and to the same extent as provided above
                         with respect to the voting rights of the Company Stock
                         or SAIC Stock, subject to the rules prescribed by the
                         Committee, which rules, among other matters, may
                         prescribe that no action shall be taken with respect
                         to shares as to which no direction is received from
                         Participants.  The Trustee shall have no discretion
                         with respect to the exercise of any such rights,
                         except as may be required by applicable law.

                   (v)   Neither the Committee nor the Trustee shall make any
                         recommendation to any Participant regarding the
                         exercise of the Participant's voting rights or any
                         other rights under the provisions of this Section
                         10.18, nor shall the Committee or Trustee make any
                         recommendation as to whether any such rights should or
                         should not be exercised by the Participant.

          (b)      All responses to tender and exchange for Company Stock or
                   SAIC Stock offers shall be made in accordance with the
                   following provisions:

                   (i)  Each Participant shall be given the opportunity, to the
                        extent that shares of Company Stock or SAIC Stock are
                        allocated to his Account, to direct the Trustee in
                        writing as to the manner in which to respond to a
                        tender or exchange offer with respect to Company Stock
                        or SAIC Stock, and the Trustee shall respond in
                        accordance with the instructions so received.  The
                        Trustee shall not divulge to the Company or Science
                        Applications International Corporation, as the case may
                        be, the instructions of any Participant.  The Committee
                        shall utilize its best efforts to timely distribute or
                        cause to be distributed to each Participant such
                        information as will be distributed to shareholders in
                        connection with any such tender or exchange offer,
                        together with a form addressed to the Trustee
                        requesting confidential instructions on whether or not
                        such shares will be tendered or exchanged.  If the
                        Trustee shall not receive timely direction from a
                        Participant as to the manner in which to respond to
                        such a tender or exchange offer, the Trustee shall not
                        tender or exchange any shares of Company Stock or SAIC
                        Stock with respect to which such Participant has the
                        right of direction, and the Trustee shall have no
                        discretion in such matter, except as may be required by
                        applicable law.

                   (ii) Shares of Company Stock or SAIC Stock held by the
                        Trustee pending allocation to Participants' Accounts
                        shall be tendered or exchanged (or not tendered or
                        exchanged) by the Trustee in the same proportion as
                        shares with respect to which Participants have been
                        given the opportunity to direct the Trustee pursuant to
                        paragraph (i) above are tendered or exchanged, and the
                        Trustee shall have no discretion in such matter, except
                        as may be required by applicable law.

          10.19    PLAN EXPENSES.  All expenses incurred in the establishment,
administration and operation of the Plan, including but not limited to the
expenses incurred by the members of the Committee in exercising their duties,
to the extent these expenses are not paid by the Company, shall be charged to
the Trust Fund and accounted for pursuant to the provisions of Article VI.

          (a)      Costs or expenses which are particular to a specific asset
                   or group of assets in the Trust Fund, such as interest and
                   brokerage charges which are included in the cost of
                   securities purchased by the Trustee (or charged to proceeds
                   in the case of sales), as determined by the Committee, shall
                   be charged or allocated in a fair and equitable manner to
                   the Accounts, subaccounts or funds to which those assets are
                   allocated pursuant to rules prescribed by the Committee.

                       MERGER OF COMPANY; MERGER OF PLAN

          11.1     EFFECT OF REORGANIZATION OR TRANSFER OF ASSETS.  In the
event of a consolidation, merger, sale, liquidation, or other transfer of the
operating assets of the Company to any other company, the ultimate successor or
successors to the business of the Company shall automatically be deemed to have
elected to continue this Plan in full force and effect, in the same manner as
if the Plan had been adopted by resolution of its board of directors, unless
the successor(s), by resolution of its board of directors, shall elect not to
so continue this Plan in effect, in which case the Plan shall automatically be
deemed terminated as of the applicable effective date set forth in the board
resolution.

          11.2     MERGER RESTRICTION.  This Plan and its related Trust shall
not in whole or in part merge or consolidate with, or transfer its assets or
liabilities to any other plan or trust unless each affected Participant in this
Plan would receive a benefit immediately after the merger, consolidation, or
transfer (if the Plan then terminated) which is equal to or greater than the
benefit he would have been entitled to receive immediately before the merger,
consolidation, or transfer (if the Plan had then terminated).

                              PLAN TERMINATION AND
                        DISCONTINUANCE OF CONTRIBUTIONS

          12.1     PLAN TERMINATION.  Subject to the following provisions of
this Section 12.1, the Company may terminate the Plan and the Trust Agreements
at any time and for any reason by an instrument in writing executed in the name
of the Company by an officer or officers duly authorized to execute such an
instrument, and delivered to the Trustee.  The Company expressly disavows any
contractual obligation, implied or otherwise, to continue this Plan.

          (a)      The Plan and Trust Agreements may terminate if the Company
                   merges into any other corporation, if as a result of the
                   merger the corporate entity of the Company ceases, and the
                   Plan is terminated pursuant to the rules of Section 11.1.

          (b)      Upon and after the effective date of the termination, the
                   Company shall make no further contributions under the Plan
                   and no contributions need be made by the Company applicable
                   to the Plan Year in which the termination occurs, except as
                   may otherwise be required by law.

          (c)      The rights of all affected Participants to benefits accrued
                   to the date of termination of the Plan, to the extent funded
                   as of the date of termination, shall automatically become
                   fully vested as of that date.

          12.2     DISCONTINUANCE OF CONTRIBUTIONS.    The Company by
resolution of its Board of Directors may discontinue contributions to the Plan
at any time and for any reason in the Board's sole discretion.  Upon and after
the effective date of this discontinuance, the Company shall make no further
Company Contributions under the Plan and no Company Contributions need be made
by the Company with respect to the Plan Year in which the discontinuance
occurs, except as may otherwise be required by law.

          (a)      The discontinuance of Company Contributions on the part of
                   the Company shall not terminate the Plan as to the funds and
                   assets then held by the Trustee, or operate to accelerate
                   any payments of distributions to or for the benefit of
                   Participants, Beneficiaries or Alternate Payees, and the
                   Trustee shall continue to administer the Trust Fund in
                   accordance with the provisions of the Plan until all of the
                   obligations under the Plan shall have been discharged and
                   satisfied.

          (b)      However, if this discontinuance of Company Contributions
                   shall cause the Plan to lose its status as a qualified plan
                   under Code section 401(a), the Plan shall be terminated in
                   accordance with the provisions of this Article XII.

          (c)      On and after the effective date of a discontinuance of
                   Company contributions, the rights of all affected
                   participants to benefits accrued to that date, to the extent
                   funded as of that date, shall automatically become fully
                   vested as of that date.

          12.3     RIGHTS OF PARTICIPANTS.  In the event of the termination of
the Plan, for any cause whatsoever, all assets of the Plan, after payment of
expenses, shall be used for the exclusive benefit of Participants and their
Beneficiaries and no part thereof shall be returned to the Company, except as
provided in Article IV of this Plan or as otherwise permitted by law.

          12.4     TRUSTEE'S DUTIES ON TERMINATION.  Upon termination of the
Plan, the Committee shall determine whether to continue the Trust, to
distribute the assets of the Trust to Participants, Beneficiaries and Alternate
Payees, to transfer the assets in the Trust to another qualified plan
maintained by the Company, or to take other action consistent with applicable
law.

          (a)      If so directed by the Committee upon termination of this
                   Plan, the Trustee shall proceed as soon as possible to
                   reduce all of the assets of the Trust Fund to cash and/or
                   common stock and other securities in such proportions as the
                   Committee shall determine (after approval by the Internal
                   Revenue Service, if necessary or desirable, with respect to
                   any portion of the assets of the Trust Fund held in common
                   stock or

                                                                   June 25, 1999


                   securities of the Company).  After first deducting the
                   estimated expenses for liquidation and distribution
                   chargeable to the Trust Fund, and after setting aside a
                   reasonable reserve for expenses and liabilities (absolute or
                   contingent) of the Trust, the Committee shall make the
                   allocations required under Article VI, where applicable,
                   with the same effect as though the date of completion of
                   liquidation were an Anniversary Date of the Plan.  Following
                   these allocations, the Trustee shall promptly, after receipt
                   of appropriate instructions from the Committee, distribute
                   in accordance with such instructions to each former
                   Participant, or Beneficiary or Alternate Payee, a benefit
                   equal to the amount credited to his Accounts as of the date
                   of completion of the liquidation.

          (b)      The Trustee and the Committee shall continue to function as
                   such for such period of time as may be necessary for the
                   winding up of this Plan and for the making of distributions
                   in accordance with the provisions of this Plan.

          12.5     PARTIAL TERMINATION.  In the event of a partial termination
of the Plan within the meaning of Code section 411(d)(3), the interest of
affected Participants in the Trust Fund, as of the date of the partial
termination, shall become nonforfeitable as of that date.

          (a)      That portion of the assets of the Plan affected by the
                   partial termination shall be used exclusively for the
                   benefit of the affected Participants and their
                   Beneficiaries, and no part thereof shall otherwise be
                   applied.

          (b)      With respect to Plan assets and Participants affected by a
                   partial termination, the Committee and the Trustee shall
                   follow the same procedures and take the same actions
                   prescribed in this Article XII in the case of a total
                   termination of the Plan.

          12.6     FAILURE TO CONTRIBUTE.  The failure of the Company to
contribute to the Trust in any year, shall not, in and of itself, constitute a
complete discontinuance of contributions to the Plan.

                                  ARTICLE XIII
                            APPLICATION FOR BENEFITS

          13.1     APPLICATION FOR BENEFITS; CLAIMS PROCEDURE.  The Committee
may require any person claiming benefits under the Plan to submit an
application therefor in such form or medium as the Committee shall prescribed,
together with such documents and information as the Committee may require.  In
the case of any person suffering from a disability which prevents the claimant
from making personal application for benefits,

                                                                   June 25, 1999


the Committee may, in its discretion, permit another person acting on his
behalf to submit the application.

          13.2     ACTION ON APPLICATION.  Within ninety (90) days following
receipt of an application and all necessary documents and information, the
Committee's authorized delegate reviewing the claim shall furnish the claimant
with written notice of the decision rendered with respect to the application.

          (a)      In the case of a denial of the claimant's application, the
                   written notice shall set forth:

                   (i)    The specific reasons for the denial, with reference to
                         the Plan provisions upon which the denial is based;

                   (ii)  A description of any additional information or
                         material necessary for perfection of the application
                         (together with an explanation why the material or
                         information is necessary); and

                   (iii) An explanation of the Plan's claim review
                         procedure.

          (b)      A claimant who wishes to contest the denial of his
                   application for benefits or to contest the amount of
                   benefits payable to him shall follow the procedures for an
                   appeal of benefits as set forth in Section 13.3 below, and
                   shall exhaust such administrative procedures prior to
                   seeking any other form of relief.

          13.3     APPEALS.  A claimant who does not agree with the decision
rendered with respect to his application may appeal the decision to the
Committee.

                   (i)  The appeal shall be made, in writing, within sixty-five
                        (65) days after the date of notice of the decision with
                        respect to the application.

                   (ii) If the application has neither been approved nor denied
                        within the ninety-day period provided in Section 13.2
                        above, then the appeal shall be made within sixty-five
                        days (65) after the expiration of the ninety-day
                        period.

          (a)      The claimant may request that his application be given full
                   and fair review by the Committee.  The claimant may review
                   all pertinent documents and submit issues and comments in
                   writing in connection with the appeal.

          (b)      The decision of the Committee shall be made promptly, and
                   not later than sixty (60) days after the Committee's receipt
                   of a request for review,

                                                                   June 25, 1999


                   unless special circumstances require an extension of time
                   for processing, in which case a decision shall be rendered
                   as soon as possible, but not later than one hundred twenty
                   (120) days after receipt of a request for review.

          (c)      The decision on review shall be in writing and shall include
                   specific reasons for the decision, written in a manner
                   calculated to be understood by the claimant with specific
                   reference to the pertinent Plan provisions upon which the
                   decision is based.

                                  ARTICLE XIV
                        LIMITATIONS ON ANNUAL ADDITIONS

          14.1     MAXIMUM ANNUAL ADDITIONS.  The Annual Additions of a
Participant shall not exceed the maximum permissible amount specified in Code
section 415(c)(1).

          14.2     EFFECT OF PARTICIPATION IN OTHER COMPANY PLANS.  If a
Participant in this Plan is also a Participant in another defined contribution
plan maintained by the Company, the aggregate Annual Additions of the
Participant under this Plan and such other plan(s) shall not exceed the maximum
permissible amount specified in Code section 415(c)(1).  In order to avoid
having the aggregate Annual Additions exceed the limit, the Participant's
Elective Deferrals may be limited.  If limitation (down to zero) of such
Elective Deferrals does not sufficiently reduce the Annual Additions to come
within the limit, allocations of the Company Contributions to the Participant
shall be reduced.

          To the extent allocations to a Participant are reduced, such reduced
amounts shall be allocated and reallocated to other Participants in the
applicable Plan.

          If as a result of (i) forfeitures, (ii) a reasonable error in
estimating a Participant's Annual Compensation, (iii) a reasonable error in
determining the amount of Elective Deferrals that may be made with respect to
any individual under the limits of Code section 415, or (iv) under other
limited facts and circumstances that the Commissioner of Internal Revenue finds
as justifying the rules set forth in this subsection 14.2(a), the Annual
Additions under the terms of this Plan and other retirement plans of the
Company would cause the limitations of Code section 415 applicable to that
Participant to be exceeded, the excess amounts shall not be deemed Annual
Additions if Elective Deferrals within the meaning of Code section 402(g)(3)
are distributed to the Participant under the terms of this Plan.  Such
distributed amounts shall be disregarded for purposes of Code section 402(g)
and the average deferral percentage test of Code section 401(k)(3).

          (a)      If a Participant in this Plan is also a Participant in a
                   defined benefit plan maintained by the Company, the sum of
                   the Defined Contribution Plan Fraction (as defined in Code
                   section 415(e)(3)) and the Defined Benefit Plan Fraction (as
                   defined in Code section 415(e)(2)) shall not exceed 1.0.

                                                                  June 25, 1999
                   The Participant's benefit under such defined benefit plan
                   shall be reduced, as necessary to satisfy the requirement of
                   the preceding sentence.

          14.3     INCORPORATION BY REFERENCE OF CODE SECTION 415.  In order to
ensure compliance with Code section 415, the Plan hereby incorporates said
Section by reference as though it were set out as part of this Plan.  In
applying Section 415 to this Plan, the Plan shall include each grandfather or
transition rule provided by such Section or any law amending such Section, in
order to allow the largest benefit otherwise payable hereunder, or under other
plans maintained by the Company, to be paid.

          14.4     NO CONTRACTUAL RIGHT TO EXCESS CONTRIBUTIONS.  If, in order
to comply with the limitations of this Article XIV, it becomes necessary to
reduce a Participant's Account(s), to reduce or reallocate amounts previously
allocated to such Accounts, or otherwise, such action(s) may be taken by the
Committee and Trustee free of any contractual obligation to the Participant (or
Beneficiary) affected based on prior Account balances or allocations.

                                   ARTICLE XV
                  RESTRICTION ON ALIENATION; PARTICIPANT LOANS

          15.1     GENERAL RESTRICTIONS AGAINST ALIENATION.  Except as
otherwise provided by law and as otherwise provided by Sections 15.2 and 15.3:

          (a)      The interest of any Participant, Beneficiary or Alternate
                   Payee in the income, benefits, payments, claims or rights
                   hereunder, or in the Trust Fund shall not in any event be
                   subject to sale, assignment, hypothecation, or transfer.
                   Each Participant, Beneficiary or Alternate Payee is
                   prohibited from anticipating, encumbering, assigning, or in
                   any manner alienating his or her interest under the Trust
                   Fund, and is without power to do so, except as may otherwise
                   be provided for in the Trust Agreement.  The interest of any
                   Participant, Beneficiary or Alternate Payee shall not be
                   liable or subject to his debts, liabilities, or obligations,
                   now contracted, or which may be subsequently contracted.
                   The interest of any Participant, Beneficiary or Alternate
                   Payee shall be free from all claims, liabilities, bankruptcy
                   proceedings, or other legal process now or hereafter
                   incurred or arising; and the interest or any part thereof,
                   shall not be subject to any judgment rendered against the
                   Participant, Beneficiary or Alternate Payee.

          (b)      In the event any person attempts to take any action contrary
                   to this Article XV, that action shall be void and the
                   Company, the Committee, the Trustee and all Participants,
                   their Beneficiaries and Alternate Payees may disregard that
                   action and are not in any manner bound thereby, and

                                                                   June 25, 1999


                   they, and each of them separately, shall suffer no liability
                   for any disregard of that action, and shall be reimbursed on
                   demand out of the Trust Fund for the amount of any loss,
                   cost or expense incurred as a result of disregarding or of
                   acting in disregard of that action.

          (c)      The preceding provisions of this Section 15.1 shall be
                   interpreted and applied by the Committee in accordance with
                   the requirements of Code section 401 (a)(13) as construed
                   and interpreted by authoritative judicial and administrative
                   rulings and regulations.

          15.2     NONCONFORMING DISTRIBUTIONS UNDER COURT ORDER.  Benefits
shall be paid to an Alternate Payee if such payment is required pursuant to a
qualified domestic relations order, as defined in Code sections 401(a)(13) and
414(p).

          In the event that the Plan receives a domestic relations order, the
Committee or its delegate shall promptly notify the Participant and any
Alternate Payee (i.e., spouse, former spouse, child or other dependent of a
participant who is recognized by a domestic relations order as having a right
to receive all, or a portion of, the benefits payable under the Plan with
respect to such Participant) of the receipt of such order and the Plan's
procedures for determining the qualified status of such orders, and within a
reasonable period of time after receipt of such order, the Committee shall
determine whether such order is a qualified domestic relations order and notify
the Participant and each Alternate Payee of such determination.  In determining
the qualified status of a domestic relations order and in administering
distributions under such qualified orders, the Committee shall follow the
following procedures:

          (a)      When the Plan receives a domestic relations order affecting
                   Plan benefits, the Committee or its delegate shall promptly
                   notify each person specified in the order as entitled to
                   benefits under the Plan (using the address(es) included in
                   the domestic relations order) of the Plan procedure as set
                   forth herein (and as supplemented, if necessary, by
                   Committee procedures)

          (b)      The Plan shall permit an Alternate Payee to designate a
                   representative for receipt of copies of notices that are
                   sent to the Alternate Payee with respect to a domestic
                   relations order.

          (c)      The Committee shall review any domestic relations order to
                   determine if it satisfies the requirements of being a
                   qualified domestic relations order.  In making such
                   determination, the Committee may seek the advice of legal
                   counsel to the Plan and may rely upon the legal opinion of
                   such counsel in determining the qualified status of domestic
                   relations orders and appropriate measures to resist or
                   implement such orders.  The Committee may, but need not,
                   enter an appearance on behalf of the Plan





                                       63
<PAGE>   71

                                                                  June 25, 1999


                   in the domestic relations lawsuit, if any, and may pursue
                   such legal remedies as may be desirable for resisting
                   unqualified orders or in modifying proposed orders.

          (d)      During any period in which the issue of whether a domestic
                   relations order is a qualified domestic relations order is
                   being determined by the Committee, by a court of competent
                   jurisdiction, or otherwise, the Committee shall segregate in
                   a separate account in the Plan or in an escrow account the
                   amounts, if any, which would have been payable to the
                   Alternate Payee during such period if the order had been
                   determined to be a qualified domestic relations order.  If,
                   within eighteen (18) months it is determined that the order
                   is not a qualified domestic relations order or the issue as
                   to whether such order is a qualified domestic relations
                   order is not resolved, than the Committee shall pay the
                   segregated amounts (plus any interest thereon) to the person
                   or persons who would have been entitled to such amounts if
                   there had been no order.  Any determination that an order is
                   a qualified domestic relations order which is made after the
                   close of the aforementioned eighteen-month period shall be
                   applied prospectively only, should there be any
                   undistributed benefits of the Participant to which the order
                   related.

          (e)      If the Committee or other fiduciary of the Plan acts in
                   accordance with the foregoing procedures in treating a
                   domestic relations order as being (or not being) a qualified
                   domestic relations order or taking action to segregate an
                   account and ultimately make payment thereof in accordance
                   with subparagraph (d) above, then the Plan's obligations to
                   the Participant and each Alternate Payee shall be discharged
                   to the extent of any payment made pursuant to such act.

          15.3     AUTHORIZED PARTICIPANT LOANS.  The Committee may authorize
loans from the Trust Fund to Participants (including, for this purpose,
Suspended Participants) pursuant to rules prescribed by the Committee at any
time and from time to time.  These rules shall be designed to ensure that
Participant loans satisfy the requirements of Code sections 4975(d)(1) and
72(p), and any other provision of law that is, or may become, applicable.  The
decision as to whether or not any Participant Loans shall be made under this
Section 15.3 shall be made in the sole discretion of the Committee, and the
Participant shall not have a contractual right to obtain a loan hereunder.
These rules shall provide, among other things, that:

          (a)      The loans are available to all Participants on a reasonably
equivalent basis.

                                                                   June 25, 1999



          (b)      Unless otherwise determined by the Plan Administrator, a
                   Participant shall direct the source (i.e., from which
                   Account, and from which investments within an Account, if
                   the Account from which a loan is to be made has more than
                   one available investment choice) from which a loan shall be
                   made.  If the Participant fails to direct the source of any
                   loan, or if the source(s) selected by the Participant is not
                   sufficient to accommodate the loan, then the loan shall be
                   taken from all Accounts and all investment choices within an
                   Account on a pro-rata basis.  Notwithstanding the foregoing,
                   no loan shall be taken from the Participant's SAIC Employer
                   Stock Account or SAIC Matching Account.

          (c)      The loans are not made available to Highly Compensated
                   Employees in amounts greater than the amounts made available
                   for other Employees.  For this purpose, the rules prescribed
                   by the Committee may restrict the amount of the loan to a
                   percentage of the Participant's Account balance or to use
                   different percentages depending upon the amount of the loan,
                   provided the percentages are applicable to all Participants.
                   The Committee may also prescribe rules pursuant to which the
                   portion of an individual's Account that is invested in
                   Company Stock or SAIC Stock (or a fund within the Trust to
                   which Company Stock or SAIC Stock is allocated) may (or may
                   not) be taken into account in determining the maximum loan
                   he may obtain.

          (d)      The loans bear interest at the prime rate (as identified in
                   a source to be selected by the Plan Administrator) or such
                   other reasonable rate of interest determined by the Plan
                   Administrator.

          (e)      The loans are adequately secured.  For this purpose, the
                   amount of the security must be at least equal to the amount
                   of the loan.  The rules to be prescribed by the Committee
                   may permit a Participant to use up to his entire Vested
                   Interest under the Plan as security for the loan.

          (f)      If the loan is to be secured by some or all of the
                   Participant's Accounts under the Plan, the Participant and
                   his spouse, if any, must consent to the loan and the
                   possible reduction in the Accounts in the event of a set off
                   of the loan against the Account balances as a result of
                   nonpayment of the loan.  Such consent must be given in
                   writing within a ninety-day period before the Committee
                   makes the loan.  In the event the Participant defaults on
                   the loan and Participant's Accounts are security for the
                   loan, the Account balances will not be used to satisfy the
                   loan obligation prior to the earlier of the Participant's
                   termination of employment with the Company or an event
                   resulting in a permissible distribution of his Accounts
                   under the Plan.  In the event of default, the Company shall

                                                                   June 25, 1999


                   offset the amount owed by the Participant against any
                   amounts owed by the Company to the Participant.

          (g)      The loan must state the date upon which the loan must be
                   repaid, which may not exceed five years (except in the case
                   of loans used to acquire a dwelling unit which, within a
                   reasonable time after the loan is made, is to be used as the
                   principal residence of the Participant), and the loan must
                   be repayable in substantially level payments, with payments
                   not less frequently than quarterly.

          (h)      In connection with the making of any loan to a Participant
                   pursuant to the provisions of this Section 15.3, the
                   Participant receiving such a loan may be required to execute
                   such documents as may be required by the Committee and/or
                   Trustee.

          (i)      The amount of the loan may not exceed the lesser of:

                   (i)  $50,000 (reduced by the excess of the highest
                        outstanding balance of loans from the Plan during the
                        one-year period ending on the date preceding the date
                        on which such loan is made over the outstanding balance
                        of loans from the Plan on the date on which such loan
                        was made); or

                   (ii) One-half of the present value of the Participant's
                        Vested Interest in his Accounts.  For purposes of this
                        Section 15.3(i), the Participant's Vested Interest and
                        outstanding loan balances in all qualified employer
                        plans (as such term is defined in Code section
                        72(p)(3)) of the Company shall be aggregated to
                        determine whether a loan shall be permissible hereunder
                        and the maximum permissible amount thereof.

          (j)      In the event the Participant dies prior to distribution of
                   his Distributable Benefit, the amount payable to his
                   Beneficiary or spouse, as applicable, shall be reduced by
                   the amount of the security interest in the Participant's
                   vested interest held by the Plan by reason of a loan
                   outstanding to such Participant.

          (k)      In addition to the foregoing, the loan rules promulgated by
                   the Committee shall include the following:

                   (i)  The identify of the person or positions authorized to
                        administer the Participant loan program;

                   (ii) The procedures for applying for a loan;

                                                                   June 25, 1999



                   (iii) The basis on which loans will be approved or denied;

                   (iv)  Limitations on the types and amounts of loans offered;
                         and

                   (v)   The events constituting default and the steps that
                         will be taken to preserve Plan assets in the event of
                         such default.

          (l)      Notwithstanding the foregoing provisions of this section
                   15.3, loan repayments may be suspended in accordance with
                   Code section 414(u)(4).

                                  ARTICLE XVI
                                PLAN AMENDMENTS

          16.1     AMENDMENTS.  The Board of Directors in its sole discretion
may at any time, and from time to time, amend the Plan by an instrument in
writing executed in the name of the Company by an officer or officers duly
authorized to execute such instrument, and delivered to the applicable Trustee.
However, except as provided in Section 16.2 no amendment shall be made at any
time, the effect of which would be:

          (a)      To cause any assets of the Trust Fund to be used for or
                   diverted to purposes other than providing benefits to the
                   Participants and their Beneficiaries, and defraying
                   reasonable expenses of administering the Plan, except as
                   provided in Article IV or as otherwise permitted by law;

          (b)      To have any retroactive effect so as to deprive any
                   Participant or Beneficiary of any benefit to which he would
                   be entitled under this Plan if his employment were
                   terminated immediately before the amendment; or

          (c)      To increase the responsibilities or liabilities of a Trustee
                   or an Investment Manager without its written consent.

          16.2     RETROACTIVE AMENDMENTS.  The Plan may be amended
prospectively or retroactively (as provided in Code section 401(b)) to make the
Plan conform to any provision of ERISA, any Code provisions dealing with
tax-qualified employees' trusts, or any regulation under either.

                                  ARTICLE XVII

          (b)      This Plan is part of a Required Aggregation Group of plans,
                   but not part of a Permissive Aggregation Group, and the
                   Top-Heavy Ratio for the group of plans exceeds 60%.

          (c)      This Plan is a part of a Required Aggregation Group and part
                   of a Permissive Aggregation Group of plans and the Top-Heavy
                   Ratio for the Permissive Aggregation Group exceeds 60%.

          17.3     DEFINITIONS.  For purposes of this Article XVII, the

          (c)      Permissive Aggregation Group: The Required Aggregation Group
                   of plans plus any other plan or plans of the Company that,
                   when considered as a group with the Required Aggregation
                   Group, would continue to satisfy the requirements of Code
                   sections 401 (a)(4) and 410, and which are designated by the
                   Company to constitute a Permissive Aggregation Group.

          (d)      Required Aggregation Group: (1) Each plan of the Company in
                   which a Key Employee is a Participant or was a Participant
                   at any time during the determination period (regardless of
                   whether the Plan has terminated) and (2) any other qualified
                   plan of the Company that enables a plan described in (1) to
                   meet the requirements of Code section 401(a)(4) or 410.

          (e)      Top-Heavy Ratio:

                   (i)  If the Company maintains one or more defined
                        contribution plans (including any Simplified Employee
                        Pension) and the Company has not maintained any defined
                        benefit plan that during the five-year period ending on
                        the Determination Date has or has had accrued benefits,
                        the Top-Heavy Ratio for this Plan alone or for the
                        Required Aggregation Group or Permissive Aggregation
                        Group, as appropriate, is a fraction, the numerator of
                        which is the sum of the Account balances of Key
                        Employees as of the Determination Date (including any
                        part of any account balance distributed in the
                        five-year period ending on the Determination Date), and
                        the denominator of which is the sum of all account
                        balances (including any part of any account balance
                        distributed in the five-year period ending on the
                        Determination Date), both computed in accordance with
                        Code section 416 and regulations thereunder.  Both the
                        numerator and denominator of the Top-Heavy Ratio are
                        adjusted to reflect any contributions not actually made
                        as of the Determination Date, but which is to be taken
                        into account on that date under Code section 416 and
                        regulations thereunder.

                   (ii) If the Company maintains one or more defined
                        contribution plans (including any Simplified Employee
                        Pension) and the Company maintains or has maintained
                        one or more defined benefit plans that during the
                        five-year period ending on the Determination Date has
                        or has had any accrued benefits, the Top-Heavy Ratio
                        for any Required or Permissive Aggregation Group, as
                        appropriate, is a fraction, the numerator of which is
                        the sum of Account balances under the aggregated
                        defined contribution plan or plans for all Key
                        Employees determined in accordance with (1) above and
                        the present value of accrued benefits under the
                        aggregated defined benefit plan or plans

                         for all Key Employees as of the Determination Date,
                         and the denominator of which is the sum of the Account
                         balances under the aggregated defined contribution
                         plan or plans for all Participants determined in
                         accordance with (1) above, and the present value of
                         accrued benefits under the defined benefit plan or
                         plans for all Participants as of the Determination
                         Date, all determined in accordance with Code section
                         416 and the regulations thereunder.  The accrued
                         benefits under a defined benefit plan in both the
                         numerator and denominator of the Top-Heavy Ratio are
                         adjusted for any distribution of an accrued benefit
                         made in the five-year period ending on the
                         Determination Date. Solely for the purpose of
                         determining if the Plan, or any other plan included in
                         a Required Aggregation Group is top-heavy (within the
                         meaning of Code section 416(g)), the accrued benefit
                         of an Employee other than a Key Employee shall be
                         determined under (i) the method, if any, that
                         uniformly applies for accrual purposes under all plans
                         maintained by the Company and any Affiliated Companies
                         or (ii) if there is no such method, as if such benefit
                         accrued not more rapidly than the slowest accrual rate
                         permitted under the fractional accrual rate of Code
                         section 411(b)(1)(C).

                   (iii) For purposes of (i) and (ii) above, the value of
                         Account balances and the present value of accrued
                         benefits will be determined as of the most recent
                         Valuation Date that falls within or ends with the
                         twelve-month period ending on the Determination Date,
                         except as provided in Code section 416 and regulations
                         thereunder for the first and second Plan Years of a
                         defined benefit plan.  The Account balances and
                         accrued benefits of a Participant (A) who is not a Key
                         Employee but who was a Key Employee in a prior year or
                         (B) who has not been credited with at least one Hour
                         of Service with any Company maintaining the Plan at
                         any time during the five-year period ending on the
                         Determination Date will be disregarded.  The
                         calculation of the Top-Heavy Ratio, and the extent to
                         which distributions, rollovers and transfers are taken
                         into account, will be made in accordance with Code
                         section 416 and regulations thereunder.  Voluntary
                         deductible contributions will not be taken into
                         account in computing the Top-Heavy Ratio.  When
                         aggregating plans, the value of account balances and
                         accrued benefits will be calculated with reference to
                         the Determination Dates that fall within the same
                         calendar year.

                   (iv)  For purposes of establishing the present value in
                         order to compute the Top-Heavy Ratio any benefit shall
                         be discounted only for mortality and interest based on
                         the interest rate that would be used as

                                                                   June 25, 1999


                         of the date of distribution by the Pension Benefit
                         Guaranty Corporation to determine the present value of
                         a lump-sum distribution on plan termination.

          (f)      Valuation Date: The date as of which Account balances or
                   accrued benefits are valued for purposes of calculating the
                   Top-Heavy Ratio.

          17.4     ADJUSTMENT TO FRACTIONS.  In any Plan Year in which the Plan
is Top-Heavy, in applying the limitations of Code section 415, the denominator
of the Defined Benefit Fraction shall be computed using 100% of the dollar
limitation instead of 125%, and the maximum aggregate amount used with respect
to the denominator of the Defined Contribution Fraction shall be computed by
using 100% of the dollar limitation instead of 125%.

          17.5     VESTING REQUIREMENTS.  If the Plan is determined to be a
Top-Heavy Plan in any Plan Year, then a Participant's right to his Accounts
derived from Company Contributions, determined as of the end of such Plan Year,
shall vest in accordance with the following schedule, unless a more rapid
vesting schedule is then in effect under the terms of the Plan:

<TABLE>
<CAPTION>
YEARS OF VESTING SERVICE                       VESTING PERCENTAGE
- ------------------------                       ------------------
            <S>                                        <C>
            2                                           20%
            3                                           40%
            4                                           60%
            5                                           80%
            6 or more                                   100%
</TABLE>

If the Plan ceases to be a Top-Heavy Plan in any Plan Year, then the vesting
schedule set forth in Article VII shall apply for such Plan Year with respect
to any portion of a Participant's Accounts that is forfeitable as of the
beginning of such Plan Year; provided, however, that a Participant with three
or more years of vesting service shall be given the option of remaining under
the vesting schedule set forth above.

          17.6     MINIMUM CONTRIBUTION.  If this Plan is a Top-Heavy Plan in
any Plan Year, the Company Contributions for such year for each "participant"
(as defined for the purpose of providing mandatory minimum contributions under
regulations) who is not a Key Employee shall not be less than three percent
(3%) of such participant's compensation.  If, however, the Plan does not enable
a defined benefit plan to meet the requirements of Section 401(a)(4) or 410,
the Company Contributions shall not exceed that percentage of each
participant's compensation which is equal to the highest percentage of
compensation at which Company Contributions are made for the Plan Year for any
Key Employee (a) under the Plan or (b) if the Plan is part of an Aggregation
Group, under any defined contribution plan in such Group.  The percentage of

compensation at which Company Contributions are made for a Key Employee shall
be computed without regard to compensation in excess of the ceiling on
includible compensation set forth in Section 17.7 of this Article XVII.  For
Plan Years beginning before January 1, 1989, for purposes of this Section 17.6,
Company Contributions attributable to a salary reduction or similar arrangement
and contributions made pursuant to Chapter 21 of Title 11 of the Social
Security Act shall be disregarded.  For Plan Years beginning after December 31,
1988, Company Contributions attributable to a salary reduction or similar
arrangement made by Employees other than Key Employees shall not be taken into
account under this Section 17.6.

          17.7     CEILING ON INCLUDIBLE COMPENSATION.  If this Plan is
determined to be a Top-Heavy Plan in any Plan Year, then only the first
$150,000 of a Participant's Compensation shall be taken into account in
determining the allocation to the Accounts of such Participant for the Plan
Year.  The $150,000 limit shall automatically be adjusted for such Plan Years
and to such extent as is permitted by the Secretary of the Treasury.

                                 ARTICLE XVIII
                                 MISCELLANEOUS

          18.1     NO ENLARGEMENT OF EMPLOYEE RIGHTS.  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 to be
consideration for, or an inducement to, or a condition of, the employment of
any Employee.

          (a)      Nothing contained in this Plan or the Trust shall be deemed
                   to give any Employee the right to be retained in the employ
                   of the Company or to interfere with the right of the Company
                   to discharge or retire any Employee at any time.

          (b)      No Employee, or any other person, shall have any right to or
                   interest in any portion of the Trust Fund other than as
                   specifically provided in this Plan, and no Employee or any
                   other person shall be entitled to rely upon any
                   representations, whether oral or in writing, including
                   representations made in the summary plan description, any
                   prospectus or other document, which is inconsistent with
                   this Plan document.

          18.2     MAILING OF PAYMENTS; LAPSED BENEFITS.  All payments under
the Plan shall be delivered in person or mailed to the last address of the
Participant or Beneficiary furnished pursuant to Section 18.3 below.

          (a)      In the event that a benefit is payable under this Plan to a
                   Participant or Beneficiary and after reasonable efforts such
                   individual cannot be located for the purpose of paying the
                   benefit during a period of three consecutive years following
                   the date payment would otherwise have been made, the

                                                                   June 25, 1999


                   benefit shall be forfeited and allocated in the same manner
                   as Additional Company Contributions.  If the Participant or
                   Beneficiary later makes a valid claim for the benefit, the
                   claim shall be paid pursuant to directions by the Committee.

          (b)      For purposes of this Section 18.2, the term "Beneficiary"
                   shall include any person entitled under Section 9.9 to
                   receive the interest of a deceased Participant or deceased
                   designated Beneficiary and shall also include an Alternate
                   Payee.

          (c)      The Accounts of a Participant shall continue to be
                   maintained until the amounts in the Accounts are paid to the
                   Participant or his Beneficiary.  In the event that the Plan
                   is terminated and the Committee directs the Trustee to
                   liquidate the Trust and distribute the assets of the Trust
                   Fund, the following rules shall apply:

                   (i)   All Participants and Beneficiaries (including
                         Participants and Beneficiaries who have not previously
                         claimed their benefits under the Plan) shall be
                         notified of their right to receive a distribution of
                         their interests in the Plan.

                   (ii)  All Participants and Beneficiaries shall be given a
                         reasonable length of time, which shall be specified in
                         the notice, in which to claim their benefits.

                   (iii) All Participants (and their Beneficiaries) who do not
                         claim their benefits within the designated time period
                         shall be presumed to be dead.  The Accounts of such
                         Participants shall be forfeited at such time. These
                         forfeitures shall be disposed of according to rules
                         prescribed by the Committee, which rules shall be
                         consistent with applicable law.  Alternatively the
                         Committee may, but shall not be required to, deposit
                         such funds in an applicable state unclaimed property
                         or similar fund, pursuant to applicable state law.

                   (iv)  The Committee shall prescribe such rules as it may
                         deem necessary or appropriate with respect to the
                         notice, deposit or forfeiture rules stated above.

          (d)      Should it be determined that the preceding rules relating to
                   forfeiture of benefits upon Plan termination are
                   inconsistent with any of the provisions of the Code and/or
                   ERISA, these provisions shall become inoperative without the
                   need for a Plan amendment and the Committee shall prescribe
                   rules that are consistent with the applicable provisions of
                   the Code and/or ERISA.

                   person or by mail.  An item shall be deemed to have been
                   delivered and received by the Participant, Beneficiary or
                   Alternate Payee when it is deposited in the United States
                   Mail with postage prepaid, addressed to the Participant,
                   Beneficiary or Alternate Payee at his last address of record

                   satisfying the requirements of Code section 401(a).

          18.8     WITHHOLDING FOR TAXES.  Any payments out of the Trust Fund
may be subject to withholding for taxes as may be required by any applicable
