                        REPORT OF INDEPENDENT ACCOUNTANTS





To the Retirement Plans Committee
and Participants of the Science Applications
International Corporation Cash or Deferred Arrangement

In our opinion, the financial statements listed in the accompanying index
present fairly, in all material respects, the net assets available for benefits
of the Science Applications International Corporation Cash or Deferred
Arrangement (the Plan) at December 31, 1997 and 1996, and the changes in net
assets available for benefits for the years then ended, in conformity with
generally accepted accounting principles. These financial statements are the
responsibility of the Plan's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these statements in accordance with generally accepted auditing
standards which require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole. The additional information included in
Schedules I through III is presented for purposes of additional analysis and is
not a required part of the basic financial statements but is additional
information required by ERISA. Such information has been subjected to the
auditing procedures applied in the audit of the basic financial statements and,
in our opinion, is fairly stated in all material respects in relation to the
basic financial statements taken as a whole.

NOTE 1 - PLAN DESCRIPTION

GENERAL

The Science Applications International Corporation Cash or Deferred Arrangement
(the "Plan" or "CODA") was established on September 18, 1982 and became
effective January 1, 1983. The authority to administer the Plan is vested in the
Retirement Plans Committee (the "Committee") whose members are the Named
Fiduciaries for purposes of Section 402(a) of the Employee Retirement Income
Security Act of 1974, as amended. Generally, employees of Science Applications
International Corporation (the "Company" or "SAIC") and its subsidiaries are
eligible to participate in the Plan upon commencing employment, except for
employees in groups or units designated as ineligible. The following description
of the Plan provides only general information. Participants should refer to the
Plan document for a more complete description of the Plan's provisions.

The Plan consists of a Deferred Fund which is the fund in which assets acquired
by the Plan in its function as a qualified Cash or Deferred Arrangement are held
and accounted for. The Plan permits participants to elect to defer up to 18% of
their eligible compensation, as defined, for the Plan year and to have such
deferred amount contributed directly by the Company to the Deferred Fund for the
benefit of the participants. Such contributions are limited under Section 402(g)
of the Internal Revenue Code (the "Code") to $9,500 for the years ended December
31, 1997 and 1996. Amounts deferred by participants, including rollovers from
qualified plans, totaled $77,427,000 and $66,555,000 for the years ended
December 31, 1997 and 1996, respectively.

In addition to amounts deferred by participants, the Company, at its discretion,
may make a matching contribution equal to a specified percentage of the
aggregate amounts deferred by participants. The match is only provided on
eligible participant deferrals of up to 10% of compensation. In 1997 and 1996,
the Company contributed 50% and 30%, respectively, of the first $2,000 of a
participant's annual deferred compensation and 15% of such deferred compensation
above $2,000 for an annual total of $15,168,000 and $9,625,000, respectively.
During 1997 and 1996, the Company matching contribution was allocated to the
SAIC Stock Fund. Also, the Company, at its discretion, may make an additional
contribution to the Deferred Fund for the benefit of non-highly compensated
participants in order to comply with Section 401(k)(3) of the Code. The Company
made no additional contributions for the benefit non-highly compensated
participants during 1997 and 1996.

The Company's contribution to the Deferred Fund is to be paid in cash unless the
Company's Board of Directors determines to make the contribution in shares of
Class A Common Stock or another form. Contributions to the Deferred Fund shall
not exceed the maximum amount deductible by the Company for Federal income tax
purposes.

Employees hired prior to January 1, 1995 are immediately eligible for the
Company matching contributions. Employees hired on or after January 1, 1995, who
have elected to participate, are eligible for Company matching contributions if
they have attained age 21 and have both twelve calendar months of employment and
850 hours of service, as defined.

Participants may elect to borrow up to 50% of their vested plan balance, up to a
maximum of $50,000, excluding amounts included in the SAIC Stock Fund. Upon this
election, the loan balance is transferred from the applicable investment fund(s)
to a separate loan fund (participant loans) until repayment. Participants are
permitted to transfer to the Plan their account balances from a previous
employer's qualified retirement plan.

NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------


The participant's interest in the Deferred Fund account will be paid in a single
distribution to the participant or their designated beneficiary upon termination
of employment with the Company, retirement, permanent disability or death. A
participant may not make withdrawals from the Deferred Fund accounts while
employed with the Company prior to attaining age 59 1/2 unless the Committee
determines the participant is incurring financial hardship. After attaining age
59 1/2, a participant may make withdrawals even if still employed with the
Company. Distributions from the Deferred Fund are paid in cash.

VESTING

A participant's interest in the employee deferral portion of the Deferred Fund
account is 100% vested at all times. A participant's interest in the Company
matching contribution is 100% vested if the participant was hired prior to
January 1, 1995. If the participant was hired on or after January 1, 1995, the
participant's interest in the Company matching contribution vests at the rate of
25% per year in years three through six, becoming fully vested after six years
of service, as defined. Participants are deemed fully vested upon reaching age
59 1/2, permanent disability or death. Forfeitures, arising from participants
withdrawing from the Plan prior to achieving 100% vesting, are applied to the
Company's matching contribution. There were no Plan forfeitures applied against
Company matching contributions in 1997 or 1996.

INVESTMENT PROGRAMS

The investment programs offered to participants in the Deferred Fund allow
participants to choose among thirteen investment funds offered by the Vanguard
Group of Investment Companies. Participants are also allowed to direct a portion
of their investment into Class A Common Stock of the Company. Such investment
into the SAIC Stock Fund can be exchanged into one of the Vanguard Funds subject
to certain restrictions.

THE VANGUARD FUNDS OFFERED WERE AS FOLLOWS:

1) Vanguard Fixed Income Securities Fund - GNMA Portfolio, which invests in
fixed income securities guaranteed by the U.S. Government; 2) Vanguard Index
Trust - 500 Portfolio, which invests in common stocks; 3) Vanguard Money Market
Reserves - Prime Portfolio, which invests in money market instruments; 4)
Vanguard Fixed Income Securities Fund - Short Term Federal Portfolio, which
invests in U.S. government obligations; 5) Vanguard/ Wellesley Income Fund,
which invests in fixed income securities and common stocks; 6) Vanguard/Windsor
Fund, which invests in common stocks; 7) Vanguard International Growth
Portfolio, which invests in common stocks of companies based outside the United
States; 8) Vanguard U.S. Growth Portfolio, which invests in common stocks; 9)
Vanguard Fixed Income Securities Fund - Intermediate - Term Corporate Portfolio,
which invests primarily in investment grade corporate bonds; 10) Vanguard
LIFEStrategy Income Portfolio, which invests in common stocks, bonds and short
term reserves; 11) Vanguard LIFEStrategy Conservative Growth Portfolio, which
invests in common stocks, bonds and short term reserves; 12) Vanguard
LIFEStrategy Moderate Growth Portfolio, which invests in common stocks and
bonds; and 13) Vanguard LIFEStrategy Growth Portfolio, which invests in common
stocks and bonds. Separate Deferred Fund accounts are established for each
investment program selected by a participant. Participants may elect to transfer
their existing account balances at any time among the Vanguard investment funds
and/or alter the allocations of future contributions among any of the investment
alternatives under rules prescribed by the Committee.

PLAN TERMINATION

Although the Company has not expressed any intent to terminate the Plan, it
reserves the right to suspend or discontinue contributions to the Plan or to
terminate the Company's participation in the Plan at any time. In the event of
termination, a distribution of the participants' Deferred Fund account balances
will be made in accordance with the Plan provisions.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF ACCOUNTING

The accompanying financial statements are prepared on the accrual basis of
accounting.

INVESTMENT VALUATION AND INCOME, GAINS AND LOSSES

Vanguard Funds

Deposits to the Vanguard Funds are used to buy shares from the respective
investment fund. Vanguard Fund shares are valued at the net asset value per
share as of each valuation date.

Investment transactions are accounted for on the date the shares in the fund are
purchased or sold. Realized and unrealized gains and losses are computed based
on the market value at the beginning of the year or purchase price if purchased
during the year.

SAIC Common Stock

A general public market for the Company's Common Stock does not exist;
therefore, the fair market value of the Common Stock is determined pursuant to a
stock price formula and valuation process which includes an appraisal prepared
by an independent appraisal firm. Periodic determinations of fair market value
of the Common Stock are made by the Board of Directors, with the assistance of
the independent appraisal firm. The Board of Directors reserves the right to
alter the formula.

The gains or losses realized on distributions of investments and the increases
or decreases in unrealized appreciation are calculated as the difference between
the current fair market value and the fair market value of the investments at
the beginning of the year or purchase price if purchased during the year. As of
December 31, 1997 and 1996, the fair market value of the Company's Class A
Common Stock was $34.78 per share and $22.83 per share and the Plan held
approximately 7,599,000 shares and 6,994,000 shares, respectively.

It is the policy of the Committee to keep the SAIC Stock Fund invested primarily
in Common Stock, except for estimated reserves for use in distributions and
investment exchanges by participants. Such reserves are invested in the Vanguard
Money Market Reserves - Prime Portfolio mutual fund. If reserves in the SAIC
Stock Fund are less than the amount required at any given time to make requested
distributions and investment changes, investment exchanges out of the SAIC Stock
Fund by participants may have to be deferred.

Short-term investments

Short-term investments consist primarily of State Street Bank and Trust
Short-Term Investment Fund, which invests in short-term money market
instruments. State Street Bank and Trust Company is the Plan's Trustee.

CONTRIBUTIONS

Participant contributions and Company matching contributions are accrued based
upon the amounts deferred by participants at year end which are received by the
Trustee subsequent to year end. Additional Company contributions are accrued
based upon the amounts determined by the Company's Board of Directors (Note 1).

These amounts are reflected as liabilities in the Plan's Form 5500.

ADMINISTRATIVE EXPENSES OF THE PLAN

All expenses incurred in the administration of the Plan are paid out of Plan
assets unless the Company elects to pay such costs. Fees totaling $88,000 and
$52,000 were paid or accrued to the Trustee by the Plan during 1997 and 1996,
respectively. Other Plan expenses totaling $63,000 and $111,000 were paid or
accrued by the Plan during 1997 and 1996, respectively.

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.
