          PRELIMINARY PROXY SOLICITING MATERIAL DATED JANUARY 18, 2002

                                 [INFODATA LOGO]

                                                               January ___, 2002

Dear Fellow Shareholder:

         The board of directors of Infodata Systems Inc. ("Infodata") has
unanimously approved an Agreement and Plan of Merger, dated as of January 10,
2002, by and among Infodata, Science Applications International Corporation
("SAIC") and Info Acquisition Corp., a wholly-owned subsidiary of SAIC, and is
seeking your approval of the transaction. If the merger is completed, Infodata
shareholders will receive $1.00 in cash for each share of Infodata common stock
they own and Infodata will become a wholly-owned subsidiary of SAIC.

         The Infodata board of directors believes that the merger is in the best
interests of Infodata and its shareholders and unanimously recommends that you
vote "FOR" approval of the merger agreement. Investec PMG Capital, Infodata's
financial advisor, has advised the board that the merger consideration is fair
to Infodata's shareholders from a financial point of view.

         Infodata has scheduled a special meeting of Infodata's shareholders to
be held on March 1, 2002 at 10:00 a.m., local time at Infodata's corporate
headquarters located at 12150 Monument Drive, Fairfax, Virginia 22033. At the
special meeting, you will be asked to consider and vote on a proposal to approve
the merger agreement. The $1.00 per share cash merger consideration represents a
premium of approximately 41% over the $.71 closing price of Infodata common
stock on January 10, 2002, which was the business day prior to public
announcement of the merger agreement.

         Your participation in the special meeting, in person or by proxy, is
important. Even if you anticipate attending in person, we urge you to mark, sign
and return the enclosed proxy card promptly in the enclosed postage-paid
envelope to ensure that your shares of Infodata common stock will be represented
at the special meeting. If you do not vote, it will have the same effect as
voting against the merger.

         In the materials accompanying this letter, you will find a notice of
special meeting, a proxy statement relating to the actions to be taken by
Infodata's shareholders at the special meeting and a proxy card. The proxy
statement provides you with detailed information about the merger. I encourage
you to read the notice and the entire proxy statement carefully.

                                          Richard Bueschel

                                          Chairman of the Board

                           TO BE HELD ON MARCH 1, 2002

To Our Shareholders:

         Notice is hereby given that a special meeting of the shareholders of
Infodata Systems Inc. will be held at Infodata's corporate headquarters located
at 12150 Monument Drive, Fairfax, Virginia 22033 at 10:00 a.m., local time, on
March 1, 2002, for the following purposes:

     1.  To consider and vote on a proposal to approve the Agreement and Plan of
         Merger, dated as of January 10, 2002, by and among Infodata Systems
         Inc., Science Applications International Corporation ("SAIC") and Info
         Acquisition Corp., a wholly-owned subsidiary of SAIC, providing for the
         merger of Info Acquisition with and into Infodata, with Infodata
         becoming a wholly-owned subsidiary of SAIC; and

    2.   To consider and act on any other matters properly coming before the
         special meeting and any adjournment or postponement of the meeting.

         The board of directors has determined that only holders of record of
Infodata common stock at the close of business on January 22, 2002 are entitled
to vote at the special meeting or any adjournment or postponement thereof.
Approval of the merger proposal at the special meeting requires the affirmative
vote of the holders of more than 66-2/3% of the outstanding shares of Infodata
common stock.

         Your vote is important. Whether or not you are able to attend the
meeting, please date, sign and return the accompanying proxy card promptly in
the enclosed envelope which requires no postage if mailed in the United States.
Please do not send in any stock certificates at this time. Upon approval of the
merger, you will be sent instructions regarding the procedure to exchange your
stock certificates for the cash to be paid.

                                          By Order of the Board of Directors


                                          Curtis D. Carlson, Secretary

January ___, 2002

          Please mark, sign, date and return your proxy card promptly,
             whether or not you plan to attend the special meeting.

         recommends that shareholders vote "FOR" the proposal to approve
                  the merger agreement at the special meeting.


                                 PROXY STATEMENT

                              INFODATA SYSTEMS INC.
                             Corporate Headquarters
                              12150 Monument Drive
                                Fairfax, VA 22033

                         SPECIAL MEETING OF SHAREHOLDERS

                           TO BE HELD ON MARCH 1, 2002

         This proxy statement is being furnished to the shareholders of Infodata
Systems Inc., a Virginia corporation, in connection with the solicitation by its
board of directors of proxies to be used at a special meeting of shareholders to
be held on Friday, March 1, 2002 at 10:00 a.m., local time, at Infodata's
corporate headquarters located at 12150 Monument Drive, Fairfax, Virginia 22033
and at any adjournment or adjournments thereof.

         At the special meeting, the shareholders of Infodata will be asked to
consider and vote on a proposal to approve an Agreement and Plan of Merger,
dated as of January 10, 2002 by and among Infodata Systems Inc., Science
Applications International Corporation ("SAIC") and Info Acquisition Corp., a
wholly-owned subsidiary of SAIC. A copy of the Agreement and Plan of Merger is
attached to this proxy statement as Appendix A.

         Pursuant to the Agreement and Plan of Merger, (i) Info Acquisition
Corp. will be merged with and into Infodata and (ii) each outstanding share of
common stock, $0.03 par value, of Infodata, will be canceled and converted
automatically into the right to receive $1.00 in cash, payable to the
shareholder thereof, without interest. As a result of the merger, SAIC will own
all of the outstanding shares of Infodata's common stock and Infodata's
shareholders will no longer have an equity interest in Infodata.

         Only Infodata shareholders at the close of business on January 22, 2002
are entitled to notice of and to vote at the special meeting or any
adjournment(s) thereof. Under Virginia law, approval of the merger agreement
requires the affirmative vote of holders of more than 66-2/3% of the outstanding
shares of common stock entitled to vote at the special meeting. Each share of
common stock is entitled to one vote on all matters to come before the special
meeting. The common stock is the only outstanding class of our capital stock.

         Neither the Securities and Exchange Commission nor any state securities
commission has approved or disapproved of the transaction, passed upon the
merits or fairness of the transaction, or passed upon the adequacy or accuracy
of the disclosure in this document. Any representation to the contrary is
unlawful.

             This Proxy Statement is dated and is first being mailed
           to shareholders of Infodata on or about January ___, 2002.

                               SUMMARY TERM SHEET

         The following summary briefly describes the material terms of the
proposed merger whereby Infodata will become a wholly-owned subsidiary of SAIC.
This summary does not contain all the information that may be important for you
to consider when evaluating the merger. We encourage you to read this proxy
statement in its entirety before voting. The sections below include references
to direct you to more complete descriptions of the matters discussed in this
summary.

         If the merger is completed, you will receive the cash merger
consideration of $1.00 per share, without interest, for each share of Infodata
common stock owned by you. Holders of each outstanding option to purchase
Infodata common stock with an exercise price less than $1.00 per share will be
entitled to receive cash in an amount equal to the difference between $1.00 per
share and the applicable exercise price of the option. See "Questions and
Answers About the Merger," "The Merger" and "The Merger Agreement" beginning on
pages 5, 14 and 23, respectively.

         The most relevant aspects and consequences of the merger are summarized
as follows:

         o        Infodata shareholders and holders of options to purchase
                  Infodata common stock will no longer have any equity interest
                  in Infodata.

         o        All outstanding Infodata stock options and warrants will be
                  cancelled.

         o        Infodata will no longer be a public company.

         o        All Infodata common stock will be owned by SAIC. See "The
                  Merger Agreement - Description of the Merger" beginning on
                  page 24.

         o        The merger is subject to several conditions, including
                  obtaining the affirmative vote of the holders of more than
                  66-2/3% of the outstanding shares of Infodata common stock,
                  our entering into a new lease reducing the amount of our
                  office space, the continuity of a significant contract, the
                  updating of records relating to certain of our contracts,
                  maintenance of tangible net worth at least $925,000 at
                  December 31, 2001, and other customary closing conditions. See
                  "The Merger Agreement-Conditions to the Merger" beginning on
                  page 28.

         o        Our board of directors has unanimously determined that the
                  merger is advisable, fair to, and in the best interests of,
                  Infodata and its shareholders and unanimously recommends that
                  you approve the merger agreement. See "The Merger -
                  Recommendation of the Infodata Board of Directors" beginning
                  on page 16.

         o        Our board of directors has received an opinion from Investec
                  PMG Capital, Infodata's financial advisor, to the effect that
                  the cash merger consideration to be received by Infodata
                  shareholders is fair, from a financial point of view, to our
                  shareholders. See "The Merger - Fairness Opinion of Infodata's
                  Financial Advisor" beginning on page 21.

         o        The merger agreement must be approved by the affirmative vote
                  of the holders of more than 66-2/3% of the outstanding shares
                  of Infodata common stock. Current directors and officers and a
                  former director of Infodata holding an aggregate of
                  approximately 19% of Infodata's outstanding common stock have
                  agreed to vote in favor of the merger agreement. See "The
                  Special Meeting - Record Date and Voting Rights and
                  Requirements" beginning on page 11.

         o        Infodata shareholders are entitled to dissenters' rights under
                  Virginia law. See "The Merger - Rights of Dissenting
                  Shareholders" beginning on page 19.

         o        The receipt of the cash merger consideration by Infodata
                  shareholders will be a taxable transaction. See "The Merger -
                  Material Federal Income Tax Consequences" beginning on page
                  19.

                                       4

         o        If the merger agreement is terminated, Infodata may be
                  required to pay SAIC a break-up fee and/or reimburse SAIC for
                  merger-related expenses, with the maximum amount of such fee
                  and expenses ranging between $50,000 and a maximum $400,000
                  depending on the circumstances. SAIC may be required under
                  certain circumstances if the merger agreement is terminated to
                  pay Infodata a break-up fee and reimburse our merger-related
                  expenses, with the amount of such fee and expenses limited to
                  a maximum of $400,000. See "The Merger Agreement - Termination
                  Fees and Expenses" beginning on page 31.

         o        Infodata has granted to SAIC an option to purchase 400,000
                  shares of Infodata common stock at an exercise price of $1.00
                  per share that will be exercisable under certain circumstances
                  by SAIC in the event the merger agreement is terminated. See
                  "The Merger Agreement - SAIC Option to Acquire Shares of
                  Infodata Common Stock" beginning on page 32.


                     QUESTIONS AND ANSWERS ABOUT THE MERGER

Q:       What am I being asked to vote on at the special meeting?

A:       You are being asked to vote on the merger agreement that provides for
         the merger of a wholly-owned subsidiary of SAIC with and into Infodata
         with Infodata becoming a wholly-owned subsidiary of SAIC.

Q:       What percentage vote of shareholders is required to approve the merger
         proposal?

A:       The merger proposal must be approved by the affirmative vote of the
         holders of more than 66-2/3% of our outstanding shares of common stock.

Q:       What will I receive when the merger is consummated?

A:       You will receive $1.00 in cash as merger consideration in exchange for
         each of your shares of Infodata common stock if the merger occurs. In
         addition, the holder of each option with an exercise price less than
         $1.00 per share will receive the difference between $1.00 per share and
         the exercise price per share set forth in the relevant stock option
         agreement.

Q:       Will members of Infodata's management team receive anything different
         in the merger?

A:       Yes. Certain members of management will receive bonuses if the merger
         occurs. These bonus arrangements are described in further detail in
         "The Merger - Interests of Certain Persons in the Merger - Bonus
         Arrangements." Furthermore, certain members of our management will be
         entitled to severance benefits under existing employment agreements
         with us if the merger is consummated and their employment is
         terminated. See "The Merger - Interests of Certain Persons in the
         Merger - Severance Arrangements Under Existing Employment Agreements."

Q:       Why is Infodata proposing the merger?

A:       Infodata is proposing the merger because its board of directors
         believes that the merger is a more desirable alternative than
         continuing to operate as a public company with limited resources.

Q:       How does the board of directors recommend that I vote?

A:       The board of directors has determined that the merger is desirable and
         fair to you and in the best interests of Infodata and its shareholders,
         and recommends that you vote "FOR" approval of the merger proposal. In
         making this determination, the board of directors considered many
         factors including the opinion of its financial advisor, Investec PMG
         Capital, that the $1.00 per share to be received by you in cash in the
         merger is fair to you from a financial point of view.

         After carefully reading and considering the information contained in
         this proxy statement, you should fill out and sign your proxy card. You
         should then mail your completed, signed proxy card in the enclosed
         return envelope as soon as possible so that your shares can be voted at
         the special meeting.

         If you intend to vote to approve the merger agreement, you should mark
         the box on the proxy card to indicate that you vote "FOR" the merger
         agreement. You should return your proxy card whether


                                       5


         or not you plan to attend the special meeting. If you attend the
         special meeting, you may revoke your proxy at any time before it is
         voted and vote in person.

Q:       If my shares are held in "street name" by my broker, will my broker
         vote my shares for me?

A:       Your broker will not be able to vote your shares without instructions
         from you. You should follow the directions provided by your broker to
         vote your shares.

Q:       What happens if I do not send in my proxy card, or if I abstain from
         voting?

A:       If you do not send in your proxy card, or do not instruct your broker
         to vote your shares "FOR" the merger, or if you abstain from voting, it
         will have the same effect as a vote against the merger proposal.

Q:       May I change my vote after I have mailed my signed proxy card?

A:       Yes. You may change your vote by sending in a later-dated, signed proxy
         card or a written revocation before the special meeting or by attending
         the special meeting and voting in person. Your attendance at the
         meeting will not, by itself, revoke your proxy. If you have instructed
         a broker to vote your shares, you must follow the directions received
         from your broker to change those instructions.

Q:       Should I send my stock certificates now?

A:       No. If the merger is completed, we will send you written instructions
         for exchanging your stock certificates for the cash payment.

Q:       What are the tax consequences of the merger?

A:       The merger will be a taxable transaction to you for federal income tax
         purposes. See "The Merger - Material Federal Income Tax Consequences".
         You should consult your tax advisor as to the tax effects of the merger
         in your particular circumstances.

Q:       What rights do I have to dissent from the merger?

A:       If you wish, you may dissent from the merger and seek a judicial
         determination of the fair value of your shares, but only if you comply
         with all requirements of Virginia law which are set forth in Appendix C
         and summarized on pages 9 of this proxy statement. The judicially
         determined fair value of your shares may be more or less than the price
         per share to be paid in the merger.

Q:       When will the merger be effective?

A:       The merger will be effective when articles of merger are filed with the
         State Corporation Commission of Virginia, under the law of which
         Infodata is incorporated, and a certificate of merger is filed with the
         Secretary of State of Delaware, under the law of which Info Acquisition
         Corp. is incorporated. Subject to the satisfaction or waiver of certain
         closing conditions, we plan to file the articles and certificate on or
         about the third business day after the merger agreement is approved by
         Infodata shareholders at the special meeting.

Q:       To whom should I address questions?

A:       If you have questions or would like additional copies of this proxy
         statement, you should contact Curtis D. Carlson, Secretary of Infodata,
         at (703) 934-5205.

                                       7

INFODATA SYSTEMS INC.
12150 Monument Drive
Fairfax, Virginia 22033
(703) 934-5205

         Infodata designs, develops and delivers solutions that enable
enterprises to share, maintain and retrieve electronic documents and their
components. Infodata provides consulting and systems integration services and
products in the area of knowledge management to corporate and government
workgroups, departments and enterprises.

         The merger agreement provides that Info Acquisition Corp., a
wholly-owned subsidiary of SAIC, will merge with and into Infodata, with
Infodata becoming a wholly-owned subsidiary of SAIC. The merger agreement is
included in this proxy statement as Appendix A. Subject to the satisfaction or
waiver of certain closing conditions, we expect that the merger will become
effective promptly after the merger agreement is approved by Infodata
shareholders at the special meeting.

Reasons of Infodata for the Merger

         Infodata's board of directors approved the merger based on its
consideration of a number of material factors, including the following:

         o        Infodata's future prospects and possible alternatives to the
                  proposed merger, including the prospects for and challenges
                  and risks associated with, continuing as an independent
                  company;

         o        the substantial decline in the market price of Infodata's
                  common stock during the past five years and the view of
                  Infodata's board of directors and management that it could
                  take a long time for the market price of Infodata's common
                  stock to exceed the $1.00 per share merger consideration
                  offered by SAIC;

         o        the $1.00 per share merger consideration offered by SAIC
                  constitutes a 41% premium over the closing sale price of the
                  common stock on January 10, 2002;

         o        the opinion of Infodata's financial adviser to the effect that
                  the merger consideration is fair, from a financial point of
                  view, to Infodata's shareholders;

         o        the potential to produce significant synergies for growth due
                  to the involvement of SAIC and Infodata in providing
                  information technology services to the intelligence community;

         o        Infodata's board and management view that it could take a long
                  time for Infodata to attain the minimum net tangible assets
                  required for its common stock to be listed again on the NASDAQ
                  SmallCap market; and

         o        Infodata is currently in default and has not paid the amount
                  due under its line of credit as a result of recurring
                  operating and net losses incurred during the past several
                  years.

         The Infodata board also considered certain potentially adverse
consequences of the merger, including the potential disruption of Infodata's
business that could result from announcement of the merger, the uncertainties
regarding Infodata customers' and employees' perception of the merger and the
possibility that the merger might not be consummated. In the view of Infodata's
board, however, those considerations were not sufficient, individually or in the
aggregate, to outweigh the perceived favorable consequences and advantages of
the merger.

Recommendation of the Infodata Board of Directors

         The Infodata board of directors believes that the merger is in the best
interests of Infodata and its shareholders and unanimously recommends that you
vote "FOR" approval of the merger.


                                       8

Interests of Infodata's Directors and Officers in the Merger

         When considering the recommendation of Infodata's board, you should be
aware that one of Infodata's directors and some of its officers have interests
in the proposed transaction that are different from, or in addition to, your
interests. In particular, if the merger is consummated, three officers of
Infodata (one of whom is also a director) will be paid bonuses, and furthermore,
four officers (one of whom is also a director) will receive severance payments
under their existing employment agreements with us if their employment is
terminated after the merger.

Agreements to Vote in Favor of the Merger

         Directors and executive officers of Infodata owning an aggregate of
904,819 shares of Infodata common stock, constituting approximately 19% of the
outstanding shares, have entered into voting agreements and executed irrevocable
proxies obligating them to vote their shares in favor of the merger agreement.

Material Federal Income Tax Consequences

         The disposition of shares of Infodata common stock in the merger will
be a taxable transaction for federal income tax purposes, and may also be a
taxable transaction under applicable state, local, foreign or other tax laws. In
general, each shareholder will recognize a gain or loss in 2002 equal to the
difference, if any, between the cash payment received and the shareholder's tax
basis in the shares surrendered in the merger. You should consult with your tax
advisor about the tax consequences of the merger in light of your individual
circumstances, including the application of any federal, state, local or foreign
law.

Dissenters' Rights

         Infodata shareholders who do not vote to approve and adopt the merger
agreement may dissent from the merger and elect to have the fair value of their
shares, based on all relevant factors and excluding any element of value arising
from the accomplishment or expectation of the merger, judicially determined and
paid to them in cash. Such shareholders must deliver a written notice of intent
to demand payment for their shares prior to the taking of the vote on the merger
agreement and comply with the other requirements of Article 15 of the Virginia
Stock Corporation Act, the full text of which is attached to this proxy
statement as Appendix C. Any deviation from such requirements may result in a
forfeiture of dissenters' rights. See "The Merger -- Rights of Dissenting
Shareholders."

Fairness Opinion of Infodata's Financial Advisor

         Investec PMG Capital, Infodata's financial advisor, delivered an
opinion to Infodata's board of directors that, as of the date of execution of
the merger agreement, the consideration to be received in the merger was fair to
Infodata shareholders from a financial point of view, subject to certain
factors, qualifications and assumptions described in its opinion. The complete
opinion of Investec PMG Capital is attached as Appendix B. You should read the
opinion in its entirety.

Regulatory Requirements

         We are not aware of any material government or regulatory approvals or
actions that may be required for completion of the merger. If any governmental
or regulatory approval or action is or becomes, required, we would seek the
requisite approval or action.

                              The Merger Agreement
                                 (See page 23.)

Merger Consideration

         Under the merger agreement, upon consummation of the merger each share
of Infodata common stock will be converted into the right to receive $1.00 in
cash.

         At the effective time of the merger, all outstanding options and
warrants to purchase shares of Infodata common stock will be cancelled. Each
holder of an option with an exercise price of


                                       9


less than $1.00 per share will be entitled to receive cash in the amount of
$1.00 per share less the per share exercise price of the option.

Conditions to the Merger; Effective Date

         Infodata's and SAIC's respective obligations to complete the merger are
subject to the satisfaction or waiver of a number of conditions, including the
following, among others:

         o        The holders of more than 66-2/3% of Infodata's shares vote to
                  approve the merger agreement;

         o        No law has been passed nor court order entered prohibiting the
                  consummation of the merger;

         o        The respective representations and warranties of the parties
                  to the merger agreement must be true and correct and there
                  must not have been or be threatened a material adverse effect
                  on Infodata or its business; and

         o        Each of Infodata, SAIC and Info Acquisition Corp. must have
                  complied with its respective obligations under the merger
                  agreement.

         In addition, SAIC's obligation to complete the merger is subject to our
entering into a new lease reducing the amount of our office space, the
continuity of a significant contract, the updating of records relating to
certain of our contracts, our maintenance of tangible net worth of at least
$925,000 at December 31, 2001, and certain other customary conditions.
Infodata's obligation to complete the merger is also subject to certain
additional customary conditions.

No Solicitation of Transactions by Infodata

         The merger agreement includes provisions that prohibit Infodata from
soliciting or encouraging submission of a third party proposal, but which permit
Infodata to negotiate with and furnish information to a third party if the
Infodata board determines that failure to negotiate with or provide the
information to the third party would be inconsistent with the board's fiduciary
duties under applicable law.

SAIC Option to Acquire Shares of Infodata Common Stock

         In connection with entering into of the merger agreement, SAIC and
Infodata entered into an agreement pursuant to which Infodata has granted to
SAIC an option to purchase a total of 400,000 shares of Infodata common stock at
a price of $1.00 per share that will be exercisable by SAIC under certain
circumstances if the merger agreement is terminated.


Termination of the Merger Agreement

         The merger agreement may be terminated under certain circumstances at
any time before completion of the merger, as summarized below:

         o        By mutual consent of the parties;

         o        By either Infodata or SAIC, subject to limited exceptions, if
                  the merger has not become effective by June 30, 2002;

         o        By either Infodata or SAIC, subject to limited exceptions, if
                  the merger is not approved by holders of more than 66-2/3% of
                  Infodata's shares at the special meeting;

         o        By either Infodata or SAIC, if there is a final court order
                  that cannot be appealed prohibiting the merger;


                                       10


         o        By SAIC or Infodata, under certain circumstances, if the other
                  party has materially breached any representation, warranty,
                  covenant, or agreement contained in the merger agreement and
                  the breach is not cured within 30 business days' notice of the
                  commission of the breach;

         o        By Infodata, under certain circumstances, in order for
                  Infodata to accept a proposal from a party other than SAIC on
                  terms that would be more favorable to Infodata and its
                  shareholders than the merger;

         o        By SAIC, if the Infodata board of directors withdraws or
                  adversely modifies its approval or recommendation of the
                  merger or resolves to recommend a superior proposal from
                  another party, or if Infodata fails to enter into a new lease
                  reducing the amount of its office space, to maintain a
                  significant contract and customer relationship, and to update
                  records relating to certain of our contracts or to maintain
                  net tangible assets of $925,000 at December 31, 2001; or

         o        By SAIC, if Infodata fails (i) to enter into a new lease
                  reducing the amount of its office space, (ii) to maintain a
                  significant contract and customer relationship, (iii) to
                  update records relating to certain of our contracts, or (iv)
                  to maintain tangible net worth of $925,000 at December 31,
                  2001.

Termination Fees and Expenses

         If the merger agreement is terminated, Infodata may be required to pay
SAIC a break-up fee and/or reimburse SAIC for merger-related expenses, with the
maximum amount of such fee and expenses ranging between $50,000 and $400,000
depending on the circumstances. SAIC may be required to pay Infodata a break-up
fee and reimburse its merger-related expenses, with the amount of such fee and
expenses limited to a maximum of $400,000, under certain circumstances if the
merger agreement is terminated. See "The Merger Agreement - Termination Fees and
Expenses" beginning on page 31.

         Except as otherwise provided in the merger agreement, each party to the
merger agreement will bear its own expenses incurred in connection with the
merger agreement and the merger, whether or not the merger is consummated.

                               THE SPECIAL MEETING

         Infodata is furnishing this proxy statement to Infodata shareholders as
part of the solicitation of proxies by the Infodata board of directors for use
at a special meeting of Infodata shareholders.

Meeting Date

         The special meeting will be held at 10:00 a.m., local time, on Friday,
March 1, 2002, at Infodata's corporate headquarters located at 12150 Monument
Drive, Fairfax, Virginia 22033.

Matters to be Considered at the Special Meeting

         The purpose of the special meeting is to consider and vote on a
proposal to approve the Agreement and Plan of Merger, dated as of January 10,
2002, by and among Infodata, SAIC and Info Acquisition Corp., a wholly-owned
subsidiary of SAIC, and the merger of Info Acquisition Corp. with and into
Infodata. Upon the merger of Info Acquisition Corp. into Infodata, Infodata will
become a wholly-owned subsidiary of SAIC, and each share of Infodata common
stock outstanding as of the effective time of the merger will be converted into
the right to receive $1.00 in cash. Infodata shareholders may also be asked to
consider any other business that properly comes before the special meeting. Each
copy of the proxy statement mailed to Infodata shareholders is accompanied by a
proxy card for use at the special meeting.

Record Date and Voting Rights and Requirements

         Record Date For Voting. The close of business on January 22, 2002 is
the record date for determining holders of shares of Infodata common stock
entitled to vote at the special meeting. Each share of common stock will be
entitled to one vote. On the record date, there were [4,791,210] shares
outstanding and entitled to vote at the special meeting.

                                       11


         Voting Rights. Each share of Infodata common stock outstanding on the
record date entitles its holder to one vote on the proposal to approve the
merger agreement and on any other proposal that properly comes before the
special meeting.

         Vote Required. Approval of the merger proposal requires the affirmative
vote of more than 66-2/3% of the outstanding shares of our common stock. Certain
directors and officers, as well as a former director of Infodata, have entered
into voting agreements with SAIC pursuant to which they have committed to vote
all shares of our common stock beneficially owned by them in favor of the merger
proposal. Collectively, these individuals beneficially own an aggregate of
904,819 shares of our common stock, or 19% of the shares outstanding.

         Quorum Requirement. The presence, in person or by proxy, of shares of
Infodata common stock representing a majority of the total voting power of the
shares entitled to vote on the record date is necessary to constitute a quorum
at the special meeting.

Voting of Proxies

         A form of proxy card for your use at the special meeting accompanies
this proxy statement. Infodata shareholders may use the proxy card that came
with this proxy statement if they are unable to attend the special meeting in
person or wish to have their shares voted by proxy even if they do attend the
special meeting. All properly executed proxies that are received prior to or at
the special meeting and not revoked will be voted at the special meeting in the
manner specified. If you execute and return a proxy and do not specify
otherwise, the shares represented by your proxy will be voted "FOR" approval of
the merger proposal in accordance with the recommendation of our board of
directors. In that event, you will not have the right to dissent from the merger
and exercise your dissenters' rights under Virginia law. There are no matters
other than voting on the merger agreement that are scheduled to be brought
before the special meeting. If any other business is properly brought before the
special meeting, the persons named in the proxy will vote the shares represented
by proxies as determined in their discretion.

         If the special meeting is adjourned for any reason prior to the
approval of the merger, then the approval of the merger agreement may be
considered and voted on by shareholders at any subsequently reconvened meeting.

         Your vote is important. Please return your proxy card promptly so your
shares can be represented, even if you plan to attend the meeting in person. You
should not send any certificates representing common stock with your proxy card.
If we complete the merger, you will be sent further information regarding the
procedure for the exchange of certificates representing Infodata common stock.

Revocation of Proxies

         If you are a record holder of our common stock and you have given a
proxy pursuant to this solicitation, you may nonetheless revoke it by attending
the special meeting and giving oral notice of your intention to vote in person.
In addition, you may revoke any proxy you give at any time before the special
meeting by delivering to our Secretary a written statement revoking it or by
delivering a duly executed proxy bearing a later date. Your attendance at the
special meeting will not in and of itself constitute a revocation of your proxy.
If you have instructed a broker to vote your shares, you must follow the
directions provided by your broker to change those instructions. If you vote in
favor of the merger proposal, you will not have the right to dissent and seek
judicial determination of the fair value of your shares. If you do not send in
your proxy card or do not instruct your broker to vote your shares or if you
abstain from voting, it will have the same effect as a vote against the merger
proposal. Infodata shareholders should address any written notice of revocation
and other communications about the revocation of Infodata proxies to Infodata
Systems Inc., 12150 Monument Drive, Fairfax, Virginia, 22033, Attention:
Secretary.

         Abstentions and Broker Non-Votes. Abstentions and broker non-votes
(shares held by brokers for customers which may not be voted on the merger
because the broker has not received specific instructions from the customer)
will be counted for purposes of determining whether a quorum is present to
transact business at the special meeting, but will not be counted as "cast" for
purposes of determining whether the merger has been approved and, therefore,
will have no effect with regard to the merger. Accordingly, the board of
directors of Infodata urges each Infodata shareholder to complete, sign and date
the enclosed proxy card and return it promptly in the enclosed, postage-paid
envelope.

                                   THE MERGER

         The following description of the merger agreement and the merger does
not purport to be complete and is qualified in its entirety by reference to the
full text of the merger agreement, a copy of which is included in this proxy
statement as Appendix A and is incorporated herein by reference.

Background of the Merger

         On October 22, 2000, Infodata's board of directors engaged Investec PMG
Capital, an investment banking and advisory company, to serve as Infodata's
exclusive financial advisor to explore alternative corporate development and
shareholder value enhancement strategies.

         After reviewing all courses of action, Infodata instructed Investec PMG
Capital to market Infodata to potential acquirers. Between February and October
2001, Infodata communicated in varying degrees with over 40 companies that
expressed an interest in Infodata.

         On September 24, 2001, Steven M. Samowich, President and Chief
Executive Officer of Infodata, and Curtis D. Carlson, Secretary of Infodata, met
with several representatives of SAIC. On October 11, 2001, SAIC entered into a
confidentiality agreement with Infodata and on the following day, members of
Infodata's management met with acquisition officials of SAIC, who then proceeded
to engage in due diligence activities.

         On October 30, 2001, Infodata received a letter of intent from another
potential acquirer with whom it had been in off and on negotiations for 2
months, offering to acquire all of Infodata's outstanding shares for a price
ranging from $4.75 million to $5.7 million. However, there was no basis to
believe that the price would exceed the low end of that range. Furthermore, the
potential acquirer was a foreign company with no prior information technology
contracting experience with Infodata's primary intelligence customer and
Infodata's board of directors and management anticipated that significant costs,
delays and uncertainty would be encountered in connection with obtaining the
required governmental regulatory approvals mandated by the provisions of federal
laws regulating the acquisition by foreign companies of U.S. companies that
contract with certain U.S. government agencies. After discussing the offer with
Infodata's board of directors, Infodata management advised the potential
acquirer that Infodata did not desire to pursue the offer in view of Infodata's
receipt of a more favorable offer from SAIC, as discussed below.

         On October 30, 2001, SAIC submitted a letter of intent to Infodata
offering to acquire all of Infodata's outstanding shares of common stock for
$5.0 million. The offer was not conditioned upon the satisfaction of any
governmental regulatory approval requirement.

         On October 31, 2001, another potential acquirer offered to acquire
Infodata's Intelligence Systems Division for $4.0 million, which offer was
rejected by Infodata's board of directors as inadequate, as the board believed
it would leave Infodata with an operating base that would not be viable.

         On October 31, 2001, after discussing the terms of SAIC's letter of
intent with Infodata's board of directors, Infodata management advised SAIC of
its acceptance of SAIC's letter of intent and a 30-day exclusivity commenced.
SAIC continued due diligence activities and engaged in further discussions with
Infodata management.

         On November 2, 2001, Infodata entered into an additional agreement with
Investec PMG Capital providing that the investment advisory firm would review
and analyze the terms of the proposed merger; investigate the business,
financial condition, results of operations and prospects of Infodata; advise and
assist Infodata's board of directors with respect to the financial implications
of proceeding with the merger; and render a written opinion as to the fairness,
from a financial point of view, of the merger to Infodata shareholders.

         On November 29, 2001, Infodata received the first draft of the proposed
agreement and plan of merger from SAIC and agreed to extend the exclusivity
period for another 30 days. The November 29th draft did not quantify the amount
of consideration to be paid by SAIC in the merger. SAIC and


                                       14


Infodata officials then engaged in negotiations regarding the amount of
consideration and on December 13, 2001, SAIC offered to pay $4.83 million for
Infodata's outstanding shares, the equivalent of $1.00 per share. SAIC and
Infodata proceeded to further negotiate terms of the agreement and plan of
merger in mid-December and on January 3, 2002, representatives of Infodata and
SAIC reached an agreement that the merger consideration would be $1.00 per share
of Infodata common stock that is outstanding at the effective time of the
merger, plus the amount necessary to cash out stock options with an exercise
price of less than $1.00 per share that are outstanding at the effective time of
the merger. Infodata's board of directors held a special meeting on January 8,
2002, which was adjourned and continued on January 10, 2002, to vote on the
proposed merger. At the meeting, the principal terms of the proposed merger were
described and discussed in detail and alternative courses of action were
considered. Investec PMG Capital made a presentation regarding its analysis of
the financial terms of the proposed transaction, discussed the results of the
negotiations and expressed its opinion that the cash merger consideration was
fair to the holders of Infodata's common stock from a financial point of view.
(A copy of Investec PMG Capital's fairness opinion, dated January 10, 2002, is
set forth as Appendix B to this proxy statement.) Infodata's board of directors
unanimously adopted the agreement and plan of merger. Following receipt of the
board of directors' approval, Infodata and SAIC executed the merger agreement on
January 10, 2002, and on January 11, 2002, Infodata issued a press release
announcing the execution of the merger agreement.

Reasons for the Merger

         Infodata's board of directors approved the merger agreement and the
merger based on its consideration of a number of material factors, including the
following:

         o        Infodata's future financial outlook and possible alternatives
                  to the proposed merger, including the advantages, challenges
                  and risks associated with continuing as an independent
                  company. In this regard, the Infodata board considered the
                  amount and range of acquisition consideration most likely to
                  be offered by other prospective acquisition candidates, the
                  likelihood of realizing those values, the likelihood of
                  receiving a better financial offer from another potential
                  acquirer and the view of Infodata's management that the merger
                  represented the best strategic alternative available to
                  Infodata under the circumstances. The Infodata board also
                  considered the prospects of remaining as an independent
                  company, including Infodata's prospects for the success of its
                  business of providing complex information technology solutions
                  in the area of knowledge management and the information
                  technology services industry generally.

         o        The substantial decline in the market price of Infodata's
                  common stock during the past five years, with the average of
                  the closing sales prices of the shares declining from $9.22 in
                  1997 to $4.49 in 1998, to $2.12 in 1999, to $2.53 in 2000, to
                  $1.28 in the six months ended June 30, 2001 and to $0.79 in
                  the six months ended December 31, 2001, and the view of
                  Infodata's board of directors and management that it could
                  take a long time for the market price of Infodata's common
                  stock to exceed the $1.00 per share merger consideration
                  offered by SAIC;

         o        The $1.00 per share merger consideration offered by SAIC
                  constituted a 41% premium over the closing sale price of the
                  common stock on January 10, 2002, which was the business day
                  immediately preceding the date on which Infodata publicly
                  announced that the merger agreement had been entered into;

         o        Although Infodata's revenues increased from approximately
                  $10.3 million in 1999 to approximately $13.0 million in 2000,
                  and presently estimates that its revenues in 2001 will be
                  approximately $16.0 million, it incurred net losses of $5.0
                  million in 1999 and $2.3 million in 2000 and, without giving
                  effect to a non-recurring gain of $1.1 million in early 2001,
                  preliminarily estimates that its net loss for 2001 will be
                  approximately $1.0 million. Although estimated net income of
                  $330,000 is preliminarily expected to be recorded for the
                  fourth quarter of 2001, and profitability is expected in at
                  least the first quarter of 2002, there is no assurance such
                  profitability can be sustained in the future if Infodata were
                  to continue as an independent company.

         o        Investec PMG Capital, Infodata's financial adviser, expended
                  extensive advisory efforts over an approximate 18-month period
                  and rendered its opinion that as of the date of its opinion
                  and based upon and subject to the various considerations and
                  limitations set


                                       15


                  forth in its opinion, the $1.00 per share merger consideration
                  offered by SAIC is fair, from a financial point of view, to
                  Infodata's shareholders;

         o        SAIC, like Infodata, provides information technology services
                  to the intelligence community and the belief of Infodata's
                  board and management that the companies' activities in that
                  area of business would produce significant synergies for
                  growth;

         o        Infodata's common stock was delisted from the NASDAQ SmallCap
                  market on July 19, 2001 due to Infodata's failure to comply
                  with that market's minimum net tangible assets requirement for
                  continued listing, and Infodata's board and management
                  determination that it could take a long time for Infodata to
                  become eligible to have its common stock listed again in that
                  market; and

         o        Infodata's line of credit expired on April 30, 2001, and as a
                  result of recurring operating and net losses incurred during
                  the past four years and the nine months ended September 30,
                  2001, and continuing negative cash flow experienced in those
                  periods, Infodata has not paid the amount due under the line
                  of credit and has not negotiated a new line of credit or
                  alternative financing to pay off the amount due under the line
                  of credit.

         The Infodata board also considered certain potentially adverse
consequences of the merger, including the potential disruption of Infodata's
business that could result from the announcement of the merger, the
uncertainties regarding Infodata customers' and employees' perception of the
merger and the possibility that the merger might not be consummated. Infodata's
board, however, determined that those considerations were not sufficient,
individually or in the aggregate, to outweigh the perceived favorable
consequences and advantages of the merger.

         The Infodata board of directors considered the foregoing and other
factors as a whole, and did not attempt to quantify, rank or otherwise assign
relative weights to the specific factors it considered.

Recommendation of the Infodata Board of Directors

         At its meeting that concluded on January 10, 2002, Infodata's board of
directors voted unanimously to enter into the merger agreement and to recommend
that Infodata's shareholders vote to approve the merger agreement. Infodata's
board made its determination after careful consideration of, and based on, the
factors discussed above under "Reasons for the Merger," as well as the following
factors:

         o        the financial and valuation analyses presented to the board of
                  directors by Investec PMG Capital, including market prices and
                  financial data relating to other companies engaged in
                  businesses considered comparable to Infodata and the prices
                  and premiums paid in recent selected acquisitions of companies
                  engaged in businesses considered comparable to those of
                  Infodata;

         o        the likelihood that the merger would be consummated, including
                  the financial and operational risks to Infodata if the merger
                  were not consummated following its public announcement; and

         o        the nature of the conditions under the merger agreement to
                  SAIC's obligation to close the merger, the board's belief that
                  these conditions are expected to be satisfied and the fact
                  that the terms of the merger agreement should not unduly
                  discourage third parties from making bona fide proposals
                  subsequent to signing the merger agreement and, if any such
                  proposal were made, that Infodata's board of directors, in the
                  exercise of its good faith business judgment of the best
                  interests of Infodata and its shareholders, could authorize
                  Infodata to provide information to, engage in negotiations
                  with, and, subject to payment of the termination fee under
                  certain circumstances, enter into a transaction with, another
                  party.

         In view of the number and wide variety of factors considered in
connection with its evaluation of the merger and the complexity of these
matters, Infodata's board of directors did not find it practicable to, nor did
it attempt to, quantify, rank or otherwise assign relative weights to the
specific factors it considered. In addition, the Infodata board did not
undertake to make


                                       16


any specific determination as to whether any particular factor was favorable or
unfavorable to the board of directors' ultimate determination or assign any
particular weight to any factor, but rather conducted an overall analysis of the
factors described above, including consideration of the information, opinions,
reports and statements presented by Infodata's management and its legal and
financial advisors. In considering the foregoing factors, individual members of
the board of directors may have given different weight to different factors.
Infodata's board of directors considered all these factors as a whole, and
overall considered the factors to be favorable to, and to support, its
determination.

         Infodata's board of directors believes that the terms of the merger are
fair to and in the best interests of Infodata and its shareholders and
unanimously recommends to its shareholders that they vote "FOR" the proposal to
adopt and approve the merger.

         Directors and officers, as well as a former director of Infodata,
holding an aggregate of 904,819 shares of Infodata's common stock, constituting
approximately 19% of the outstanding shares, have entered into voting agreements
and irrevocable proxies with SAIC pursuant to which such persons have agreed to
vote their shares in favor of the merger agreement.

Certain Effects of The Merger

         As a result of the merger, the entire equity interest in Infodata will
be beneficially owned by SAIC. Infodata's shareholders will have no further
interest in Infodata except their right to receive $1.00 per share as cash
consideration for their shares. Furthermore, holders of outstanding options to
purchase Infodata common stock at an exercise price less than $1.00 per share
will be entitled to receive cash equal to the difference between $1.00 per share
and the applicable exercise price of the options. Finally, under the terms of
the merger agreement, all Infodata options and warrants outstanding as of the
effective date of the merger will be cancelled.

         In addition, Infodata common stock will no longer be traded on the OTC
Bulletin Board and price quotations with respect to sales of shares in the
public market will no longer be available. The registration of our common stock
under the Securities Exchange Act of 1934 will be terminated, and this
termination will eliminate Infodata's obligation to file periodic financial and
other information with the Securities and Exchange Commission and will make most
other provisions of the Exchange Act, such as the short-swing profit recovery
provisions of Section 16(b) and the requirements of furnishing a proxy or
information statement in connection with shareholders' meetings, no longer
applicable.

         The receipt of cash pursuant to the merger will be a taxable
transaction. See " THE MERGER - Material Federal Income Tax Consequences."

Interests of Certain Persons in the Merger

         In considering the recommendation of the board of directors with
respect to the merger, shareholders should be aware that certain officers and
directors of Infodata have interests in connection with the merger that present
them with actual or potential conflicts of interest. The board of directors was
aware of these matters, which are discussed below, and considered them in
connection with its consideration and approval of the merger.

         Bonus Arrangements

         On January 25, 2001, Infodata's board adopted a resolution to pay
bonuses to three officers and one employee of Infodata in the event of the
successful consummation of either a merger or the sale of substantially all of
Infodata's assets. Pursuant to the resolution, Steven M. Samowich (our President
and Chief Executive Officer and a director), Curtis D. Carlson (our Secretary),
Gary I. Gordon (our Chief Accounting Officer) and Eva Franklin (our Director of
Human Resources) will receive $100,000, $15,000, $15,000 and $15,000,
respectively, from Infodata if the merger is consummated.

         Stock Options

         Certain directors and officers of Infodata hold options to purchase
shares of Infodata common stock. All outstanding options will be cancelled as of
the effective time of the merger. Holders of those options with an exercise
price of less than $1.00 per share will be entitled upon


                                       17


consummation of the merger to receive a cash payment equal to $1.00 per share
minus the exercise price of the option. The following list sets forth
information regarding those options held by each director and executive officer
of Infodata, and by all directors and executive officers of Infodata as a group,
that will be entitled to receive that cash payment.

         Severance Arrangements Under Existing Employment Agreements

         On April 23, 2001, Infodata entered into executive separation
agreements with Curtis D. Carlson and Gary I. Gordon. In the event that either
officer's employment is terminated involuntarily, without cause, within six
months following a change in control of Infodata and such person is not offered
an equivalent position and compensation, that officer is entitled to separation
pay equal to four months salary and benefits.

         Infodata entered into a letter employment agreement with Steven M.
Samowich on October 29, 1998. Pursuant to the letter employment agreement, Mr.
Samowich is serving as Infodata's President and Chief Executive Officer, and
receives an annual base salary of $251,400 plus an annual incentive bonus based
on the achievement of certain management objectives and financial performance
measures. Mr. Samowich's employment with Infodata is terminable at will and is
not for a definite term. However, if Mr. Samowich is terminated by Infodata,
other than for cause, he will continue to be paid his base salary in monthly
increments for a period of 12 months.

         During 1986, Infodata entered into executive separation agreements with
Mr. Harry Kaplowitz, Executive Vice President of Infodata and Dr. Robert J.
Loane, Senior Vice President of Infodata. In the event that either officer's
employment is terminated involuntarily, without cause, following a change in
control of Infodata, that officer is entitled to separation pay equal to two
years base


                                       18


salary and continuation of life and health insurance coverage for two
years. Additionally, any type of pension or profit-sharing credited service will
be extended for two years.

Material Federal Income Tax Consequences

         The following summarizes the material federal income tax consequences
to Infodata shareholders of consummation of the merger. This summary is based on
current law, which is subject to change at any time, possibly with retroactive
effect. This summary is not a complete description of all tax consequences of
consummation of the merger and, in particular, may not address federal income
tax consequences applicable to you if you are subject to special treatment under
federal income tax law, including, without limitation, rules relating to
Infodata shareholders (i) who are not citizens or residents of the United
States, (ii) who are financial institutions, tax-exempt organizations, insurance
companies or dealers in securities, or (iii) who acquired their shares of
Infodata common stock pursuant to the exercise of options or otherwise as
compensation. In addition, this summary does not address the tax consequences of
the merger under applicable state, local or foreign laws. This discussion
assumes you hold your shares of Infodata common stock as a capital asset within
the meaning of Section 1221 of the Internal Revenue Code of 1986, as amended.

         The receipt of the merger consideration by shareholders will be a
taxable transaction for federal income tax purposes. Each shareholder will
recognize gain or loss equal to the difference between the shareholder's
adjusted basis in the common stock surrendered in the merger and the amount of
cash received therefor. Such gain or loss generally will be a capital gain or
loss provided that the shareholder held the common stock as a capital asset.
Capital gain or loss will be treated as long-term capital gain or loss if the
shareholder held the common stock for more than one year at the time of the
merger. Long-term capital gain recognized by a non-corporate shareholder is
generally subject to federal income tax at a maximum rate of 20%. In addition, a
shareholder may be limited in its ability to use capital losses to offset
ordinary income.

         Each Infodata shareholder should consult with his or her tax advisor
about the tax consequences of the merger in light of his or her individual
circumstances, including the application of any federal, state, local or foreign
law.

Rights of Dissenting Shareholders

         Shareholders of a corporation that is proposing to merge or consolidate
with another entity are sometimes entitled to appraisal or dissenters' rights in
connection with the proposed transaction depending on the circumstances. Most
commonly, these rights confer on shareholders who oppose the merger the right to
receive the fair value for their shares as determined in a judicial appraisal
proceeding, in lieu of the consideration being offered in the merger.

         Holders of record of Infodata common stock who comply with the
procedures described below will be entitled to dissenters' rights under Article
15 of the Virginia Stock Corporation Act. Where appropriate, shareholders are
urged to consult with their legal counsel to determine the appropriate
procedures for the making of a notice of intent (as described below).

         A vote in favor of the merger by an eligible holder will result in a
waiver of such eligible holder's dissenters' rights.

         The following discussion is only a summary and does not purport to be a
complete statement of the law pertaining to dissenters' rights under the
Virginia Stock Corporation Act. The text of Article 15 of the Virginia Stock
Corporation Act is reprinted in its entirety as Appendix C to this proxy
statement.

         Under the Virginia Stock Corporation Act, eligible holders who follow
the procedures set forth in Article 15 of the Virginia Stock Corporation Act
will be entitled to receive payment of the "fair value" of such shares. Any
eligible holder who wishes to exercise dissenters' rights should review the
following discussion and Appendix C carefully because failure to comply in a
timely and proper manner with the procedures specified may result in the loss of
dissenters' rights under the Virginia Stock Corporation Act.

         An eligible holder wishing to exercise dissenters' rights must deliver
to Infodata, prior to or at the shareholders' meeting (but in any event before
the vote is taken), a written notice of intent to demand payment for the
eligible holder's shares. An eligible holder delivering a notice


                                       19


of intent must not vote his shares in favor of the merger or he will lose his
dissenters' rights. All notices of intent should be sent or delivered to
Infodata Systems Inc., Attention: Secretary, 12150 Monument Drive, Fairfax,
Virginia 22033.

         Within ten days after the effective date of the merger, if the
shareholders approve the merger agreement, Infodata shall deliver a dissenter's
notice in writing to all dissenting holders. The dissenter's notice shall:

         o        state where the dissenting holder's payment demands should be
                  sent and where and when stock certificates should be
                  deposited;

         o        set a date by which the surviving corporation must receive the
                  payment demand; and

         o        include such other information as required by the Virginia
                  Stock Corporation Act.

         A dissenting holder to whom a notice is sent must demand payment within
the time specified in the dissenter's notice, deposit his stock certificates in
accordance with the terms of the dissenter's notice and make certain
certifications required by the Virginia Stock Corporation Act. Holders of
certificated shares must deposit their certificates in accordance with the
dissenter's notice. If a dissenting holder fails to take such actions, the
dissenting holder loses his dissenters' rights.

         Within 30 days of Infodata's receipt of a demand for payment from a
dissenting holder, Infodata must pay the dissenting holder Infodata's estimate
of the fair value of the dissenting holder's shares plus accrued interest. With
any payment, Infodata must provide its most recent year-end and income statement
from that year, an explanation of how Infodata calculated the fair value of the
shares and interest, the procedure a dissenter may follow if he is not satisfied
with the demand payment and a copy of Article 15 of the Virginia Stock
Corporation Act. Infodata's payment obligation may be enforced by a dissenting
holder on an expedited basis in a Virginia circuit court, if necessary.

         Infodata may elect to deliver your demand payment after the effective
time of the merger if you acquired your shares after the merger was announced or
publicized. In theses circumstances, Infodata will estimate the fair value of
the dissenting holder's shares plus accrued interest and shall offer to pay this
amount to each dissenter who agrees to accept it in full satisfaction of his
demand. With any such offer, Infodata must provide its most recent year-end and
income statement from that year, an explanation of how Infodata calculated the
fair value of the shares and interest, and the procedure a dissenter may follow
if he is not satisfied with the offer.

         A dissenting holder who is not satisfied with the amount paid or
offered by Infodata must notify Infodata of the dissenting holder's own estimate
of the fair value of his shares and the amount of interest due (less any amount
that may have been already received by the dissenting holder from Infodata) and
demand that Infodata pay this estimated amount. This notice must be given in
writing within 30 days of the date that Infodata made or offered to make payment
for the dissenting holder's shares.

         If a dissenting holder's demand for payment remains unsettled, Infodata
is obligated to commence a proceeding to determine the fair value of the shares
and accrued interest within 60 days of the receipt of the dissenting holder's
payment demand. If Infodata fails to commence such proceeding in accordance with
the Virginia Stock Corporation Act, Infodata must pay the dissenting holder the
amount demanded by the dissenting holder. The appraisal proceeding must be
brought in a Virginia circuit court.

         Dissenting holders considering seeking appraisal should be aware that
the fair value of their shares of common stock, as determined under Article 15
of the Virginia Stock Corporation Act, could be more than, the same as or less
than the merger consideration that would be paid to them pursuant to the merger
agreement. The costs and expenses of the appraisal proceeding will be determined
by the court and assessed against Infodata unless the court determines that the
dissenting holder did not act in good faith in demanding payment of the fair
value of their shares, in which case such costs and expenses may be assessed
against the dissenting holder.

         Dissenting holders will only be entitled to receive payment in
accordance with Article 15 of the Virginia Stock Corporation Act and will not be
entitled to vote their shares of common stock or


                                       20


exercise any other rights of a shareholder. A dissenting holder may withdraw his
demand only with the consent of Infodata.

         If any eligible holder who demands appraisal of his shares under
Article 15 fails to perfect, or effectively withdraws or loses, his right to
appraisal, as provided in the Virginia Stock Corporation Act, the shares of
Infodata stock of such holder will be converted into the right to receive the
merger consideration in accordance with the merger agreement.

         Failure to follow the steps required by Article 15 of the Virginia
Stock Corporation Act for perfecting dissenters' rights may result in the loss
of dissenters' rights. The preceding discussion summarizes the dissenters'
rights provisions of Article 15 of the Virginia Stock Corporation Act.
Shareholders are urged to consult Appendix C which sets forth in full Article 15
of the Virginia Stock Corporation Act. This summary is qualified in its entirety
by a reference to Article 15 of the Virginia Stock Corporation Act.

Fairness Opinion of Infodata's Financial Advisor

         Investec PMG Capital was retained by Infodata to render an opinion as
to the fairness, from a financial point of view, to Infodata's shareholders of
the consideration to be paid by SAIC in the merger. On January 8, 2002, Investec
PMG Capital rendered its oral opinion to the Infodata board of directors, and
issued a written opinion dated January 10, 2002, that as of such date, and
subject to the assumptions, factors and limitations stated in its opinion, the
consideration to be received was fair to Infodata's shareholders from a
financial point of view.

         As part of its investment banking services, Investec PMG Capital
regularly engages in the valuation of businesses and their securities in
connection with mergers and acquisitions involving both listed and unlisted
companies and their associated securities, primarily in the information
technology/professional services industries. Investec PMG Capital has acted as
financial advisor to Infodata in connection with the merger. For its services as
financial advisor, Investec PMG Capital received a retainer fee of $90,000 and
will receive an additional fee estimated to be $240,000 contingent on
consummation of the merger plus its expenses estimated to be approximately
$10,000. In addition, Investec PMG Capital received a fee of $50,000 from
Infodata for rendering its fairness opinion. The fee rendered for its fairness
opinion is not contingent upon the results of the merger.

         In arriving at its opinion, Investec PMG Capital reviewed among other
things, the final merger agreement; certain publicly available business and
financial information relating to Infodata for recent years and interim periods
to date; and certain internal financial and operating information, including
financial forecasts and projections that were provided to Investec PMG Capital
by Infodata, taking into account its growth prospects and the markets in which
it is involved. In addition, Investec PMG Capital held discussions with
management regarding the business prospects, financial outlook and operating
plans of Infodata. No limitations were imposed by Infodata on the scope of
Investec PMG Capital's investigation.

         In reviewing the merger agreement, Investec PMG Capital took into
account the financial terms of the merger as set forth in the merger agreement
in relation to, among other things, (1) current and historical market prices and
trading volumes of the Infodata common stock; (2) the limited trading volume and
public float of the Infodata common stock; (3) the historical and projected
earnings of Infodata; and (4) the performance in the public market of companies
similar to Infodata. Furthermore, Investec PMG Capital utilized a discounted
cash flow analysis to analyze the present value of the future cash flow streams
that Infodata is expecting to generate. In addition to the foregoing, Investec
PMG Capital performed such other studies, analyses and investigations and
considered such other financial, economic and market criteria as it considered
appropriate in arriving at its opinion.

         In rendering its opinion, Investec PMG Capital relied, without
verification, upon the accuracy and completeness of all financial information
and forecasts and other information provided to it by Infodata or through
publicly available sources. With respect to the financial projections and other
information provided by Infodata's management, Investec PMG Capital was advised
that in management's opinion such forecasts and other information were
reasonably prepared using the best currently available estimates and judgments
as to the financial and operational timing and achievability thereof.

                                       21


         THE FULL TEXT OF THE WRITTEN OPINION OF Investec PMG Capital DATED
JANUARY 10, 2002, WHICH SETS FORTH THE ASSUMPTIONS MADE, MATTERS CONSIDERED AND
LIMITATIONS ON THE REVIEW UNDERTAKEN, IS ATTACHED HERETO AS APPENDIX B AND
SHOULD BE READ CAREFULLY IN ITS ENTIRETY. THE OPINION OF Investec PMG Capital
WAS PREPARED FOR USE BY THE BOARD OF DIRECTORS OF INFODATA AND RELATES ONLY TO
THE FAIRNESS FROM A FINANCIAL POINT OF VIEW OF THE CONSIDERATION TO BE RECEIVED
BY INFODATA'S SHAREHOLDERS PURSUANT TO THE MERGER, AND DOES NOT CONSTITUTE A
RECOMMENDATION TO ANY SHAREHOLDER AS TO HOW SUCH SHAREHOLDER SHOULD VOTE AT THE
SPECIAL MEETING. THE SUMMARY OF THE OPINION OF Investec PMG Capital SET FORTH IN
THIS PROXY STATEMENT IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT
OF SUCH OPINION.

         In preparing its opinion, Investec PMG Capital performed a wide variety
of financial and comparative analyses as described below. The preparation of a
fairness opinion is subject to certain complex financial analyses, the
application of those methodologies to the circumstances at hand, and the global
economic and equity market conditions at the time such opinion is prepared and
accordingly does not lend itself to a summary description. As such, Investec PMG
Capital has told Infodata that it believes its analyses must be considered in
their totality and that selected portions of such analyses could be misleading
or create an incomplete view of the processes underlying such analyses and
opinion.

         Selected Company Analysis

         Investec PMG Capital compared selected historical stock market and
balance sheet data and financial ratios for Infodata to the corresponding
multiples and ratios of the following selected information technology services
companies: AnswerThink; First Consulting Group; RWD Technologies; Analysts
International; Covansys; Computer Horizons; RCM Technologies; Hall Kinion and
Assoc.; Razorfish; Sapient; CACI International; PEC Solutions; and Titan Corp.
Investec PMG Capital selected the companies used in this analysis based on a
variety of characteristics including the similarity of their size, growth,
profitability and customer base to that of Infodata. The data and ratios
Investec PMG Capital compared included, among other things, market value of
invested capital (MVIC) (current stock price multiplied by the shares
outstanding plus all indebtedness of the company plus any preferred stock
outstanding less cash and marketable securities) to last 12 months (LTM)
revenue. An analysis of MVIC to LTM revenues yielded an interquartile range of
0.25x to 1.14x with a median of 0.39x as compared to 0.30x for the contemplated
transaction. Because of Infodata's losses, as well as the losses of most of the
comparables, analyses of MVIC to LTM earnings before interest, taxes,
depreciation and amortization (EBITDA), to earnings before interest and taxes
(EBIT) and price-to-earnings ratios were not meaningful.

         Selected Transaction Analysis

         Using publicly available information, Investec PMG Capital analyzed the
purchase price and implied transaction value multiples paid in selected
transactions in the information technology services industry, consisting of
(acquirer/target): PEC Solutions/Troy Systems; Titan Corp./BTG; divine/Eprise;
divine/OpenMarket; Novell/Cambridge Technology Partners; divine/eshare
communications; divine/MarchFirst; Fusion Networks/Full Moon Interactive;
NCR/4Front Technologies; Perficient/Compete; Perot Systems/Solutions Consulting;
Drugmax.com/Desktop Corp.; Interliant/Soft Link; and CACI International/XEN
Corp. Investec PMG Capital selected the companies used in this analysis based
upon a variety of characteristics including the similarity of their size,
growth, profitability and customer base to that of Infodata. Investec PMG
Capital compared the purchase price paid (including total equity value plus
assumption of any liabilities and indebtedness less cash) in the selected
transactions as a multiple of LTM revenue. All of the multiples were based upon
information available at the time of the announcement of the transaction. Such
analysis indicated that for the selected transactions the interquartile range of
LTM revenue multiples was from 0.57x to 1.28x with a median of 0.83x (based on
12 of the identified transactions), as compared to 0.30x for the contemplated
transaction. Because information about each of the multiples described above was
not publicly available for all of the transactions identified, Investec PMG
Capital's computation of the mean and median multiples was based, in each case,
only on transactions for which relevant information about the multiple was
publicly available. Because of Infodata's losses, as well as the losses of
several of the comparables, analyses of purchase price paid to LTM earnings
before interest, taxes, depreciation and amortization (EBITDA), to earnings
before interest and taxes (EBIT) and price-to-earnings ratios were not
meaningful.


                                       22

         Selected Premium Analysis

         Using publicly available information, Investec PMG Capital reviewed the
premiums paid in merger and acquisition transactions involving companies
providing information technology services consisting of (acquirer/target): Titan
Corp./BTG; divine/Eprise; divine/OpenMarket; Novell/Cambridge Technology
Partners; divine/eshare communications; and NCR/4Front Technologies. Investec
PMG Capital compared the premium offered in these transactions for the period of
30 and 90 days prior to the announcement of a transaction (the Stated Period)
with the premium offered by the merger consideration for Infodata. This analysis
indicated that the range of premiums offered during the Stated Period was from
- -31.8% to 152.8% for the 30-day period and -2.3% to 256.6% for the 90-day period
with a median of 44.5% and 54.3%, respectively, compared to the premium offered
to Infodata of 38.9% and 58.7%, respectively.

         No company, transaction or business used in the Selected Company
Analysis, Selected Transaction Analysis, or Selected Premium Analysis as a
comparable is identical to Infodata or the merger. Accordingly, the results of
the foregoing are not entirely mathematical. Instead it involves complex
considerations and judgments concerning differences in financial and operating
characteristics of each of the businesses, which could affect the multiples
being used for comparison.

         Discounted Cash Flow Analysis

         Investec PMG Capital performed a discounted cash flow analysis of
Infodata. Investec PMG Capital calculated a net present value of discounted free
cash flows for fiscal years 2002 through 2004 using discount rates ranging from
20% to 26%. Investec PMG Capital calculated the terminal multiples in fiscal
year 2004 to range from 5.5x EBITDA to 7.0x EBITDA. These terminal values were
then discounted to their net present value using discount rates ranging from 20%
to 26%. Using the foregoing terminal values and discount rates for Infodata, the
equity value per share ranged from $0.81 to $1.10 per share as compared to the
equity value implied by the merger consideration of $1.00.

         Stock Trading History

         Investec PMG Capital examined the history of the trading prices and
volumes for the shares of Infodata common stock. This analysis showed that
during the three-month period from September 7, 2001 to December 7, 2001, the
trading price of Infodata common stock ranged from $0.88 to $0.57 with an
average price of $0.73. The merger consideration represents a premium of 37.0%
to the average stock price during that period. In addition this examination
showed that during the same period, the average daily trading volume for the
Infodata common stock was less than 1% of the outstanding shares. Further,
approximately 19% of the outstanding Infodata common stock was, at the time of
Investec PMG Capital's analysis, held by directors and executive officers of
Infodata.

         As described above, Investec PMG Capital's opinion to the board of
directors of Infodata was one of many factors taken into consideration by the
board of directors in making its determination to approve the merger agreement.
The foregoing summary of the analyses performed by Investec PMG Capital does not
purport to be a complete description of those analyses and is qualified by the
full written opinion set forth in Appendix B. Investec PMG Capital has consented
to the inclusion of its opinion as Appendix B and of the description of its
opinion in this proxy statement.

Regulatory Requirements

         We are not aware of any material government or regulatory approvals or
actions that may be required for completion of the merger. If any governmental
or regulatory approval or action is or becomes required, we would seek the
approval or action.

                              THE MERGER AGREEMENT

         The following description of the merger agreement does not purport to
be complete and is qualified in its entirety by reference to the full text of
the merger agreement, a copy of which is included in this proxy statement as
Appendix A and is incorporated herein by reference.


                                       23

Description of the Merger

         Form of Merger. Infodata, SAIC and Info Acquisition Corp. have entered
into a merger agreement, which provides that, if all of the conditions set forth
in the merger agreement are satisfied or waived, Info Acquisition Corp. will
merge with and into Infodata. Infodata will be the surviving corporation in the
merger and will become a wholly-owned subsidiary of SAIC.

         Consideration to be received by Infodata shareholders in the Merger;
Cancellation of Certificates. On the date the merger becomes effective, each
issued and outstanding share of Infodata common stock will be converted into,
and become exchangeable for, the right to receive the merger consideration in
the amount of $1.00 in cash. Certificates representing shares of Infodata common
stock immediately prior to the merger will, after the merger is effective,
represent only the right to receive, upon surrender of the certificate, the
merger consideration of $1.00 per share. Infodata shareholders will cease to
have an equity interest in, or possess any rights as shareholders of Infodata.
Each share of common stock in Info Acquisition Corp. outstanding immediately
before closing of the merger will be converted into and exchangeable for a share
of common stock in Infodata as the surviving corporation immediately after the
merger occurs.

         Treatment of Infodata Stock Options and Warrants. No later than the
effective time of the merger, each unexpired and unexercised option granted by
Infodata to purchase shares of Infodata common stock with an exercise price of
less than $1.00 per share will be cancelled in exchange for the right to receive
in cash the amount by which the $1.00 per share merger consideration exceeds the
per share exercise price of such option. All other options and warrants granted
by Infodata to purchase shares of Infodata common stock with an exercise price
of $1.00 per share or more will be canceled no later than the effective time of
the merger.

         The Effective Time. The merger will be effected by the filing of: (i)
articles of merger to the State Corporation Commission of the Commonwealth of
Virginia in accordance with the provisions of the Virginia Stock Corporation Act
and (ii) a certificate of merger with the Secretary of State of the State of
Delaware in accordance with the provisions of the Delaware General Corporation
Law promptly after the closing of the merger. The merger will become effective
at the time the articles of merger are filed with and accepted by the State
Corporation Commission of the Commonwealth of Virginia and the certificate of
merger is filed with the Secretary of the State of Delaware.

         The closing of the merger will take place as soon as practicable, and
no later than the fifth business day following satisfaction or waiver of all of
the conditions to consummation of the merger unless another date is agreed to by
Infodata, Info Acquisition Corp. and SAIC. See "The Merger Agreement--Conditions
to the Merger."

         Payment of Merger Consideration. On or prior to the date that the
merger becomes effective, SAIC will deposit into an exchange fund with a
disbursing agent the cash to be paid as the merger consideration. Promptly after
the effective time of the merger, SAIC will cause the disbursing agent to mail a
letter of transmittal to each Infodata shareholder and each holder of an option
to purchase shares of Infodata common stock with an exercise price less than
$1.00 per share. The letter of transmittal will contain instructions on how to
receive cash from the disbursing agent in exchange for outstanding shares of
Infodata common stock and/or shares purchasable under such stock option with an
exercise price of less than $1.00 per share.

         Any merger consideration deposited with the disbursing agent that has
remained unclaimed by Infodata shareholders or holders of an option to purchase
shares of Infodata common stock with an exercise price less than $1.00 per share
for one year after the effective date of the merger will be paid to SAIC upon
demand. Thereafter, record holders of Infodata common stock or holders of an
option to purchase shares of Infodata common stock with an exercise price less
than $1.00 per share that have not previously complied with the exchange
procedures pursuant to the merger agreement may look only to SAIC for payment of
any merger consideration, without interest. Any undisbursed merger consideration
shall become the property of SAIC after a period of five years following the
effective time of the merger or immediately before any payment of the merger
consideration to the record holder of Infodata common stock and/or the holder of
an option to purchase shares of Infodata common stock with an exercise price
less than $1.00 per share would become the property of any governmental agency.

         SAIC, or the disbursing agent appointed by SAIC, will be entitled to
deduct and withhold from the merger consideration any amounts that they are
required to deduct and withhold under applicable tax laws. Any amounts so
withheld will be treated for all purposes of the merger agreement as


                                       24


having been paid to the record holder of Infodata common stock and/or the holder
of an option to purchase shares of Infodata common stock with an exercise price
less than $1.00 per share in respect of which the deduction and withholding has
been made.

Covenants under the Merger Agreement

         Conduct of Infodata's Business. Infodata has agreed that until the
effective time of the merger, or unless SAIC consents in writing, that it will,
and will cause each of its subsidiaries to, conduct its operations according to
its ordinary course of business, consistent with past practice. Unless permitted

         o        amendment of articles of incorporation or bylaws;

         o        issuance, grant, pledge, creation, disposition, redemption or

         o        redemption, purchase, retirement of shares of capital stock;

         o        tax filings, audits, examinations and claims; and

         o        termination of Infodata's stock purchase plan and employees'
                  rights to purchase common stock.

         The merger agreement also contains covenants of Infodata relating to
(i) access to information about Infodata; (ii) obtaining shareholder approval of
the merger agreement, (iii) assisting SAIC in obtaining certain third party
consents to the merger, (iv) treatment of existing stock option and stock
purchase plans, (v) the non-solicitation of acquisition proposals from entities

anti-takeover statute or regulation is or may become applicable to the
transactions contemplated by the merger agreement, Infodata has agreed to take
the actions necessary to minimize the effects of the statute or regulation on
the merger and other transactions.

         The covenants in the merger agreement relating to the conduct of
Infodata's business are complicated and not easily summarized. You are urged to
read carefully the section of the merger agreement entitled "Additional
Agreements of the Parties."

         Mutual Covenants. The merger agreement contains a number of mutual
covenants of Infodata and SAIC, including covenants relating to:

                  communications received from governmental and other third
                  parties relating to the merger.

                                       27


         In addition, the merger agreement contains covenants requiring each of
the parties to:

         o        use all reasonable efforts to do, or cause to be done, all
                  things required to consummate and make effective the
                  transactions contemplated by the merger agreement, including
                  satisfying the conditions to the merger and obtaining required
                  governmental authorizations and consents;

         o        consult with each other before issuing any press release or
                  public statements with respect to the merger; and

         o        take actions to supplement securities filings relating to this
                  proxy statement as appropriate or required by law.

         Under the merger agreement, SAIC and Info Acquisition Corp. have agreed
that Infodata, as the surviving entity, will honor certain commitments, benefits
accrued and other arrangements regarding various employment, severance,
executive, change in control and other similar agreements that Infodata
currently has with its employees.

Conditions to the Merger

         The parties' respective obligations to complete the merger are subject
to the satisfaction of each of the following conditions:

         o        no statute, rule or regulation having been enacted or

                  governmental body required to permit the consummation of the
                  merger shall have been obtained and shall be in full force and
                  effect.

                  date of the closing of the merger, there must not have
                  occurred any material adverse effect on the business,
                  financial condition, results of operations, assets or
                  liabilities of Infodata and its subsidiaries, taken as a

         o        no material adverse change in Infodata's IPMS contract, which

                  that contract's maximum award fee potential and not more than
                  a 10% decrease of the billable hours allowable under that

                  correct at the time the merger is to become effective (except
                  as to any representation or warranty which speaks as of a
                  specific date, which must be true as of that date); and

         o        SAIC and Info Acquisition Corp. must have performed all of
                  their obligations and complied with all covenants necessary to
                  be performed by or complied with by either of them before the
                  effective time of the merger.

No Solicitation of Transactions by Infodata

         Prior to the time the merger becomes effective, Infodata has agreed to
certain limitations on its ability to take action with respect to any
acquisition proposal. Notwithstanding these limitations, Infodata may respond to
a superior acquisition proposal. As more fully defined in the merger agreement,

         o        the term "acquisition proposal" means any proposal or offer
                  regarding: (i) an acquisition of at least 50% of the net
                  revenue, net income or assets of Infodata and its
                  subsidiaries' business, taken as a whole, or at least 50% of
                  any shares of Infodata's capital stock or any of its
                  subsidiaries' capital stock, or (ii) any merger,
                  consolidation, business combination, recapitalization,
                  liquidation, dissolution or similar transaction involving
                  Infodata or any of its subsidiaries that constitutes at least
                  50% of the net revenues, net income or assets of Infodata and
                  its subsidiaries, taken as a whole; and

         o        the term "superior proposal" means any written proposal by a
                  third party to acquire for consideration consisting of cash or
                  securities, more than 50% of the Infodata common stock then
                  outstanding or at least 50% of the assets of Infodata and its
                  subsidiaries taken together and otherwise on terms which the
                  board of directors of Infodata, after receiving advice from
                  its financial advisor, determines in good faith to be more
                  favorable from a financial point of view to Infodata
                  shareholders than the merger.

         Infodata and each of its subsidiaries have ceased all discussions and
negotiations with third parties regarding any acquisition proposal. Prior to the
merger becoming effective, Infodata has agreed not to solicit, initiate, or
encourage or disclose directly or indirectly any information not customarily
disclosed concerning its business and properties, or afford any access to its
properties, books and records, to any person or group in connection with an
acquisition proposal


                                       29


and has agreed not to enter into any agreement with respect to any acquisition
proposal or approve any acquisition proposal.

         Prior to the special meeting of Infodata shareholders, Infodata may,
however, engage in discussions with and furnish information to a third party in
response to an unsolicited superior proposal if the board of directors of
Infodata determines in good faith, based on the advice of its outside legal
counsel that the failure to participate in those discussions or negotiations or
to furnish such information would be inconsistent with the fiduciary duties of
the Infodata board of directors under applicable law.

         Infodata has also agreed to provide SAIC with detailed information
about any inquiries or proposals, or indications of desire to make a proposal
that it receives with respect to an acquisition proposal from a third party. If
Infodata determines that it is required to provide any information to a third
party as described above or receives an acquisition proposal, Infodata must
promptly inform SAIC in writing that information is to be provided by Infodata
to such third-party, and Infodata will then furnish to SAIC the identity of the
recipient of the information or the person who submitted the acquisition
proposal and the terms of the acquisition proposal. Infodata has agreed to keep
SAIC fully informed of the status of any acquisition proposal.

         Infodata has agreed that its board of directors will not withdraw or
modify or propose to withdraw or modify, in any manner adverse to SAIC, the
board's approval or recommendation by the Infodata board of directors of the
merger agreement, the merger, or approve or recommend, or propose to approve or
recommend, any letter of intent, agreement in principle or acquisition proposal.

         However, prior to the special meeting of Infodata shareholders,
Infodata may enter into an acquisition agreement based on an unsolicited
superior proposal and concurrently terminate the merger agreement if the board
of directors determines after consultation with its outside legal counsel that
the failure to terminate the merger agreement and accept the superior proposal
would be inconsistent with the Infodata board's fiduciary duties under
applicable law. In such a circumstance, Infodata must notify SAIC in writing
that it is terminating the merger agreement to accept a superior proposal. If
the merger agreement is terminated by Infodata in order to accept a superior
proposal, Infodata is required to pay to SAIC a termination fee of $250,000 and
actual merger-related expenses up to $150,000. See "-- Termination of the Merger
Agreement."

Termination of the Merger Agreement

         The merger agreement may be terminated, and the transactions
contemplated by the merger agreement abandoned, at any time prior to the closing
of the merger, whether before or after approval of the merger agreement by
Infodata shareholders:

         o        by mutual written agreement of the parties;

         o        by either SAIC or Infodata, if the merger has not become
                  effective on or before June 30, 2002, except that the right to
                  terminate the merger agreement for that reason is not
                  available to any party responsible for the delay;

         o        by either SAIC or Infodata, if any court of competent
                  jurisdiction has issued a final and nonappealable order,
                  judgment or decree restraining or otherwise prohibiting the
                  merger;

         o        by Infodata, if SAIC or Info Acquisition Corp. has materially
                  breached any representation, warranty, covenant, or agreement
                  contained in the merger agreement and the breach is not cured
                  within 30 business days' following notice of the breach;
                  however, Infodata will not be able to terminate the merger
                  agreement in this instance if it is in material breach of any
                  representation, warranty, covenant or agreement under the
                  merger agreement;

         o        by SAIC, if Infodata has materially breached any
                  representation, warranty, covenant, or agreement contained in
                  the merger agreement and the breach is not cured within 30
                  business days' following notice of the commission of the
                  breach; however, SAIC will not be allowed to terminate the
                  merger agreement in this instance if it is in material breach
                  of any representation, warranty, covenant or agreement under
                  the merger agreement;

                                       30

         o        by either SAIC or Infodata, if the merger agreement fails to
                  receive the requisite vote by Infodata shareholders at the
                  special meeting, except that the right to terminate the merger
                  agreement in this instance is not available to any party if
                  such failure to receive the requisite vote is caused by or
                  results from the failure by that party to perform any
                  obligation under the merger agreement;

         o        by Infodata, prior to the special meeting of Infodata
                  shareholders, in order for Infodata to accept a superior
                  proposal;

         o        by SAIC if, at any time prior to the effective time of the
                  merger, the board of directors of Infodata has withdrawn,
                  modified or changed in any manner adverse to SAIC or Info
                  Acquisition Corp. its approval or recommendation of the merger
                  agreement and/or the merger; or

         o        by SAIC if, before the effective time of the merger, (i)there
                  is a material adverse change in the IPMS contract, which has
                  been defined to include not more than a 10% decrease in that
                  contract's maximum award fee potential and not more than a 10%
                  decrease of the billable hours allowable under that contract
                  as compared to the volume of billable hours during the last
                  three months of 2001; (ii) Infodata does not satisfactorily
                  update the resume files submitted to certain contract
                  customers in connection with five of Infodata's contracts;
                  (iii) Infodata is unable to obtain an amendment to its office
                  lease to reduce the total square footage under such lease to
                  result in a lease expense savings of at least $425,000 over
                  the remaining term of such lease; or (iv) Infodata does not
                  have tangible net worth of at least $925,000 as of December
                  31, 2001 with the inclusion of certain merger-related
                  expenses.

         In the event of termination of the merger agreement by SAIC, Info
Acquisition Corp. or Infodata as described above, no provision of the merger
agreement will survive other than (i) rights relating to obligations to keep
confidential, not to use, and return certain information obtained from the other
party; (ii) rights of either SAIC or Infodata to pursue legal action in
connection with breaches of representations, warranties, covenants or other
agreements contained in the merger agreement; and (iii) the obligation to pay a
termination fee and/or expenses in certain circumstances as described below.

Termination Fees and Expenses

         Pursuant to the merger agreement, Infodata or SAIC may be required to
pay a termination payment and/or expenses to the other party in the following
amounts and in the following events:

         o        In the event SAIC terminates the merger agreement due to (i)
                  the failure by Infodata to obtain the necessary approval of
                  the merger agreement by Infodata shareholders at the special
                  meeting, (ii) the failure by Infodata, on or before three
                  business days after the special meeting of its shareholders,
                  to obtain an amendment of its office lease to reduce the total
                  square footage under such lease to result in a lease expense
                  savings of at least $425,000 over the remaining term of such
                  lease, (iii) any expiration, termination or material adverse
                  change, as defined in the merger agreement, occurring in the
                  IPMS contract, or (iv) the failure by Infodata to
                  satisfactorily update the resume records submitted to contract
                  customers in connection with five contracts, then in any such
                  event, Infodata will be required to pay to SAIC the expenses
                  incurred by SAIC in this transaction up to a maximum amount of
                  $50,000; provided, however, that if within 12 months following
                  the termination of the merger agreement with SAIC, Infodata
                  executes an agreement to be acquired by another entity, then
                  Infodata will be required to pay to SAIC an additional fee
                  equal to the lesser of (A) the sum of a termination fee of
                  $250,000 and expenses incurred by SAIC up to $150,000 or (B)
                  the product of the amount determined under the preceding
                  clause (A) multiplied by a fraction, the numerator of which is
                  the aggregate acquisition consideration to be paid by SAIC.



                                       31


         o        In the event SAIC terminates the merger agreement due to a
                  breach by Infodata of the merger agreement, which breach is
                  not cured by Infodata within 30 business days following notice
                  from SAIC to Infodata of such breach or in the event
                  Infodata's board withdraws, modifies, or changes, in a manner
                  adverse to SAIC or Info Acquisition Corp., its approval or
                  recommendation of the merger agreement and/or the transactions
                  contemplated by the merger agreement, or in the event Infodata
                  terminates the merger agreement in order to accept a superior
                  proposal, or in the event Infodata does not satisfy the
                  tangible net worth condition, then in any such event Infodata
                  will be required to pay SAIC a termination fee equal to
                  $250,000 and expenses incurred by SAIC up to $150,000.

         o        In the event Infodata terminates the merger agreement due to a
                  breach by SAIC of the merger agreement, which breach is not
                  cured by SAIC within 30 business days following notice from
                  Infodata to SAIC of such breach, then SAIC will be required to
                  pay to Infodata a termination fee of $250,000 and expenses
                  incurred by Infodata up to $150,000.

         o        In each case, any termination fee and/or expenses which are
                  required to be paid under the merger agreement must be paid
                  not later than five business days after the termination of the
                  merger agreement, or if Infodata enters into a definitive
                  acquisition agreement with another party within 12 months
                  after the termination of the merger agreement with SAIC and
                  consummates such other transaction, within five business days
                  after consummation of such other business transaction.

         Except as provided above, the merger agreement provides that if the
merger agreement is not consummated, SAIC and Info Acquisition Corp., on the one
hand, and Infodata, on the other hand, will bear their respective fees and
expenses relating to the merger.

SAIC Option to Acquire Shares of Infodata Common Stock

         In connection with the entering into of the merger agreement, SAIC and
Infodata entered into a stock option agreement pursuant to which Infodata has
granted to SAIC an option to purchase a total of 400,000 shares of Infodata
common stock at a price of $1.00 that will be exercisable by SAIC under certain
circumstances if the merger agreement is terminated. SAIC will be entitled to
have that option cashed out if Infodata enters into a definitive acquisition
agreement with another company within 12 months after such termination and
subsequently consummates such transaction.

                              ACQUISITION FINANCING

         SAIC intends to use internal funds to finance the purchase of Infodata
common stock in the merger. SAIC has advised Infodata that as of the date of
this proxy statement, SAIC's available cash resources exceed $400 million. Under
the terms of the merger agreement, SAIC is obligated to continue to maintain
sufficient funds to pay the cash consideration required under the merger
agreement.

              BUSINESS AND RECENT RESULTS OF OPERATIONS OF INFODATA

Business

         Infodata designs, develops and delivers solutions that enable
enterprises to share, maintain, and retrieve electronic documents and their
components. Infodata provides consulting and systems integration services and
products in the area of knowledge management to corporate and government
workgroups, departments and enterprises.

         Revenues are generated from three segments, including (i) consulting
services, systems integration and application frameworks ("Solutions"), (ii)
sales of proprietary products ("Proprietary Products"), and (iii) the sale of
third party software and hardware ("Third Party Products").

         The Solutions business consists of designing, developing and
implementing web-based knowledge management (KM), content management, and
e-Commerce systems solutions for commercial and government clients. Solutions
represent the largest segment of Infodata's business. Proprietary Products
include INQUIRE(R)/Text, WebINQUIRE(R), Infodata's Adobe Acrobat plug-in
products Compose(R) and Aerial(R), AnnoDoc(TM), eHub(TM) and the annual support
arrangements associated with each of these products. Third Party Products refers
to software and hardware that is 1) manufactured by a third party, 2) purchased
by Infodata, and 3) resold by Infodata to its customer. Due to the low gross
margins typically associated with the sale of Third Party Products, Infodata
engages in such transactions only when they are coupled with Solutions
engagements or when the customer is of strategic importance.

Recent Results of Operations

         Infodata's revenues and net loss for the year ended December 31, 2000
were approximately $13.0 million and $2.3 million, respectively, compared to
revenues and a net loss of $10.3 million and $5.0 million, respectively, in
1999. Revenues of $11.8 million were recorded in the nine months ended September
30, 2001, compared to revenues $10.0 million in the first nine months of 2000.
Without giving effect to a non-recurring gain of $1.1 million from the sale of
an investment in the first quarter of 2001, Infodata would have recorded a net
loss of approximately $1.3 million for the nine months ended September 30, 2001.
Management of Infodata expects that Infodata's revenues for the quarter ended
December 31, 2001, will approximate $4.2 million, as compared to approximately
$3.1 million in the fourth quarter of 2000. Furthermore, management
preliminarily estimates that Infodata will record net income of approximately
$330,000 in the fourth quarter of 2001, compared to a net loss of $1.3 million
for the fourth quarter of 2000. As a result, Infodata expects that its revenues
for the full year ended December 31, 2001, will be approximately $16.0 million,
and preliminarily estimates that a net loss (without giving effect to the
non-recurring gain of $1.1 million) for 2001 will be approximately $1.0 million.

Cautionary Statement Regarding Forward-Looking Statements

         This proxy statement contains certain forward-looking statements. These
forward-looking statements are made pursuant to the safe harbor provisions of
the Private Securities Litigation Reform Act of 1995. The words "believe,"
"expect," "anticipate" and other similar expressions generally identify
forward-looking statements. You are cautioned not to place undue reliance on
these forward-looking statements, which speak only as of their dates. These
forward-looking statements are based largely on Infodata's current expectations
and are subject to a number of risks and uncertainties. Infodata undertakes no
obligation to revise the forward-looking statements publicly to reflect any
future events or circumstances.

Other Matters

         We know of no other matter to be presented at the special meeting.
However, if other matters should properly come before the special meeting, it is
the intention of the persons named in the enclosed proxy to vote the proxy with
respect to such matters in accordance with their best judgment.

Infodata Shareholder Proposal

         We do not currently expect to hold a 2002 annual meeting of
shareholders, as Infodata will be wholly-owned by SAIC if the merger is
completed. At such point, we would no longer have public shareholders or any
public participation in our shareholder meetings.

         If the merger is not completed, the annual meeting will be held, and
shareholder proposals for inclusion in our proxy statement for such 2002 annual
meeting would have to be submitted to our secretary in writing and received by
us at our corporate headquarters at 12150 Monument Drive, Fairfax, Virginia
22033, Curtis D. Carlson, Secretary of Infodata a reasonable time before we
begin to print and mail our proxy materials. Shareholder proposals must also
meet the other requirements of the SEC rules relating to shareholders proposals.

Where You Can Find More Information

         We file annual, quarterly and special reports, proxy statements and
other information with the SEC. Infodata's SEC filings are available to the
public over the Internet at the SEC's website at http://www.sec.gov. You may
also read and copy any document Infodata files at the SEC's public reference

2002, by and among SCIENCE APPLICATIONS INTERNATIONAL CORPORATION, a Delaware
corporation ("Parent"), INFODATA SYSTEMS INC., a Virginia corporation (the
"Company"), and INFO ACQUISITION CORP., a Delaware corporation and direct,

                              W I T N E S S E T H :
                              - - - - - - - - - -

       WHEREAS, the respective Boards of Directors of the Company and Merger Sub
have each approved the merger of Merger Sub with and into the Company, with the
Company surviving as a wholly-owned subsidiary of Parent (the "Merger"), on the
terms and conditions contained herein and in accordance with the Virginia Stock
Corporation Act (the "VSCA") and the Delaware General Corporation Law (the
"DGCL"), and have determined that the Merger and the transactions contemplated
herein are advisable and in the best interest of their respective corporations
and stockholders.

       WHEREAS, as a condition and inducement to Parent's willingness to enter
into this Agreement, (i) Parent, the Company and certain of the Company's
stockholders (the "Voting Stockholders") are entering into a voting agreement
and irrevocable proxy, dated as of the date hereof, substantially in the form as

and in accordance with this Agreement, and the separate existence of Merger Sub
shall cease. The Company shall be the

                                      A-1

or waiver of the conditions to Closing contained in Article VI (other than those
conditions that by their nature are to be satisfied at the Closing, but subject
to the fulfillment or waiver of those conditions), unless another date or place
is agreed to in writing by the parties hereto. The date on which the Closing
actually occurs is hereinafter referred to as the "Closing Date." As soon as is

consummated by delivering to (i) the State Corporation Commission of the
Commonwealth of Virginia (the "Commission") articles of merger (the "Articles of
Merger") and (ii) the Secretary of State of the State of Delaware a certificate
of merger (the "Certificate of Merger"), in each case, in such form as required
by, and executed and acknowledged in accordance with, the relevant provisions of
the VSCA and DGCL, as applicable. The Merger shall become effective as of the
date and at such time (the "Effective Time") as (i) the Certificate of Merger is
filed with the Secretary of State of the State of Delaware and (ii) the Articles
of Merger are filed with and accepted by the Commission, in each case, with
respect to the Merger.

       1.3 Effects of Merger. The Merger shall have the effects set forth in the
applicable provisions of the VSCA and DGCL. Without limiting the generality of
the foregoing, and subject thereto, at the Effective Time, all the properties,

Company and Merger Sub shall become the debts, liabilities and duties of the
Surviving Corporation.

Company in effect immediately prior to the Effective Time shall become, from and
after the Effective Time, the Articles of Incorporation of the Surviving
Corporation, until amended or repealed in accordance with the terms thereof and
with Applicable Laws.

Effective Time shall become, from and after the Effective Time, the Bylaws of
the Surviving Corporation, until thereafter amended or repealed in accordance
with the terms thereof and with Applicable Laws.

       1.6 Directors and Officers. The directors and officers of Merger Sub
immediately prior to the Effective Time shall become, from and after the
Effective Time, the directors and officers of the Surviving Corporation, each to
hold office from the Effective Time in accordance with the Articles of
Incorporation and Bylaws of the Surviving Corporation until their respective
successors are duly elected or appointed and qualify, or they resign or are
removed.

                                   ARTICLE II

                      EFFECT OF THE MERGER ON CAPITAL STOCK

       2.1 Conversion of Capital Stock. As of the Effective Time, by virtue of
the Merger and without any action on the part of the parties or the registered
holders of any shares of capital stock of the Company (each a "Stockholder," and
collectively, the "Stockholders"):

       (a) Each issued and outstanding share of common stock, par value $0.01
per share, of Merger Sub shall be converted into and become one fully paid and
non-assessable share of common stock, par value $0.03 per share, of the
Surviving Corporation.

       (b) Each issued and outstanding share of the Company's Common Stock, par
value $0.03 per share (the "Company Common Stock"), held by the Company or any
Company Subsidiary as treasury stock, and each issued and outstanding share of
Company Common Stock owned by Parent, Merger Sub or any other Subsidiary of
Parent (collectively, the "Parent Subsidiaries") shall automatically be canceled
and retired and shall cease to exist, and no other consideration shall be
delivered in exchange therefor.

       (c) Each issued and outstanding share of Company Common Stock, other than
(i) Company Common Stock to be canceled in accordance with clause (b) above, and
(ii) Dissenting Shares (as defined in Section 2.6), shall be converted into the
right to receive an amount in cash, without interest, equal to the Per Share
Merger Consideration, payable to the registered holder thereof, upon
satisfaction of the exchange procedures set forth in this Article II. At the
Effective Time, all such shares of Company Common Stock shall no longer be
outstanding and shall automatically be cancelled and retired and shall cease to
exist, and each registered holder of shares of Company Common Stock shall cease
to have any rights with respect thereto, except the right to receive the merger
consideration, without interest.

       (d) The parties shall accomplish the foregoing by means of the Merger,
and the amount, timing, and form of consideration to be paid to Stockholders,
and the manner of such payment, shall be as set forth in this Article II.

       2.2 Merger Consideration. Immediately subsequent to the Effective Time on
the Closing Date, upon complying with the procedures set forth in Section 2.4,
Parent shall pay, or cause the Surviving Corporation or other Company Subsidiary
to pay, to:

       (a) Each Stockholder entitled to receive a payment pursuant to Section
2.1(c), an amount in cash, without interest, equal to (i) the number of shares
of Company Common Stock registered in the name of such Stockholder immediately
prior to the Effective Time multiplied by (ii) the Per Share Merger
Consideration; and

       (b) Each holder of a Company Option (each an "Option Holder" and,
collectively, the "Option Holders") entitled to receive a payment pursuant to
Section 2.3, an amount in cash equal to (i) the number of shares of Company
Common Stock issuable pursuant to In-the-Money Options held by such Option
Holder immediately prior to the Effective Time,

                                      A-3


multiplied by (ii) the difference of (A) the Per Share Merger Consideration
minus (B) the Weighted Average Exercise Price of the In-the-Money Options held
by such Option Holder.

       2.3 Treatment of Options.

       (a) The Company shall use its reasonable best efforts, subject to any
necessary consents being received from the subject Option Holder, to cause: (i)
each option and warrant granted by the Company to purchase shares of Company
Common Stock (the "Company Options") with an exercise price per share equal to
or greater than $1.00 (the "Out-of-the-Money Options") to be irrevocably
cancelled as of the Effective Time; and (ii) each Company Option outstanding
with an exercise price per share less than $1.00 (the "In-the-Money Options") to
be fully vested and converted immediately prior to the Effective Time into the
right to receive an amount in cash, without interest, equal to (x) the excess of
the Per Share Merger Consideration over such exercise price per share of Company
Common Stock subject to such In-the-Money Option multiplied by (y) the number of
shares of Company Common Stock subject to such In-the-Money Option immediately
prior to the Effective Time. The Company shall use its reasonable best efforts
to take all action necessary to attempt to give effect to this Section 2.3 in
full (including, without limitation, using its reasonable best efforts to
attempt to obtain consents from the holders of Company Options to the
cancellation or conversion thereof, as applicable, in accordance with this
Section 2.3).

       (b) Promptly after the date of this Agreement, the Company shall cause
the adoption and approval of appropriate changes to the Company 1997 Employee
Stock Purchase Plan (the "Company Stock Purchase Plan") in order to result in no
Company stock purchase rights (each, an "ESPP Right") granted under the Company
Stock Purchase Plan to be in effect as of January 10, 2002.

       2.4 Exchange.

       (a) Prior to the Effective Time, Parent shall appoint a bank or trust
company reasonably satisfactory to the Company to act as disbursing agent (the
"Disbursing Agent") for the payment of the Aggregate Merger Consideration in
accordance with this Section 2.4 to the Stockholders and In-the-Money
Optionholders. At or prior to the Effective Time, Parent shall deposit or cause
to be deposited with the Disbursing Agent in trust for the benefit of the
Stockholders and In-the-Money Optionholders an amount in cash equal to the
Aggregate Merger Consideration (such amount being hereinafter referred to as the
"Exchange Fund").

       (b) The Disbursing Agent shall invest the Exchange Fund, as the Parent
directs, in direct obligations of the United States of America, obligations for
which the full faith and credit of the United States of America is pledged to
provide for the payment of all principal and interest or commercial paper
obligations receiving the highest rating from either Moody's Investors Service,
Inc. or Standard & Poor's, a division of The McGraw Hill Companies, or a
combination thereof, provided that, in any such case, no such instrument shall
have a maturity exceeding three months. Any net profit resulting from, or
interest or income produced by, such investments shall be payable to Parent. The
Exchange Fund shall not be used for any other purpose except as provided in this
Agreement.

                                      A-4


       (c) Promptly after the Effective Time, Parent shall cause the Disbursing
Agent to mail to each person who was a Stockholder as of the Effective Time, and
whose shares were converted into the right to receive merger consideration
pursuant to Section 2.2, and/or a holder of an In-the-Money Option (an
"In-the-Money Optionholder"), whose interests in each such option was converted
into the right to receive merger consideration pursuant to Section 2.2, a form
of letter of transmittal (which shall specify that legal delivery of their
shares of Common Stock and interests in the In-the-Money Options shall be
effected, and risk of loss and title shall pass, only upon proper delivery of
the letter of transmittal and other evidence of ownership specified therein (the
"Exchange Documentation") to the Disbursing Agent) and instructions for use in
effecting the surrender thereof in exchange for payment of the merger
consideration. Upon delivery to the Disbursing Agent of the Exchange
Documentation, together with such other documents as may be reasonably required
by the Disbursing Agent, the exchanging person or entity shall be paid promptly
in exchange therefor cash in an amount equal to (i) in the case of Common Stock,
the product of the number of shares of Company Common Stock represented by such
Exchange Documentation delivered to the Disbursing Agent, multiplied by the Per
Share Merger Consideration, and (ii) in the case of In-the-Money Options, the
number of shares of Company Common Stock issuable pursuant to In-the-Money
Options represented by Exchange Documentation delivered to the Disbursing Agent,
multiplied by the difference of (A) the Per Share Merger Consideration minus (B)
the Weighted Average Exercise Price of such In-the-Money Options. Any Company
Common Stock or Company Options tendered to the Disbursing Agent pursuant to
this Section 2.4 shall forthwith be canceled. No interest will be paid or
accrued on the cash payable upon the surrender of the Exchange Documentation.

       (d) If payment is to be made to a Person other than a registered
Stockholder or an In-the-Money Optionholder, then it shall be a condition of
payment of the merger consideration to that Person that the Exchange
Documentation be properly endorsed or otherwise be in proper form for transfer
of the securities represented thereby and that the Person requesting such
payment pay any transfer or other Taxes required by law to be paid as a result
of the payment to a Person other than the registered Stockholder or the
In-the-Money Optionholder or establish to the satisfaction of the Surviving
Corporation that such Tax has been paid or is not otherwise applicable.

       (e) At and after the Effective Time, there shall be no registration of
transfers of shares of Company Common Stock which were outstanding immediately
prior to the Effective Time on the stock transfer books of the Surviving
Corporation. At the close of business on the day of the Effective Time, the
stock ledger of the Company shall be closed.

       (f) At any time more than one (1) year after the Effective Time, Parent
shall be entitled to require the Disbursing Agent to deliver to it any funds
which had been made available to the Disbursing Agent and not disbursed in
exchange for the securities represented by the Exchange Documentation
(including, without limitation, all interest and other income received by the
Disbursing Agent in respect of all such funds). Thereafter, Stockholders and
In-the-Money Optionholders shall look only to Parent (subject to the terms of
this Agreement, abandoned property, escheat and other similar laws) as general
creditors thereof with respect to any merger consideration that may be payable,
without interest, upon due surrender of the


                                      A-5


Exchange Documentation held by them. If the Exchange Documentation shall not
have been surrendered prior to five (5) years after the Effective Time (or
immediately prior to such time on which any payment in respect hereof would
otherwise escheat to or become the property of any governmental unit or agency),
the payment in respect of such Exchange Documentation shall, to the extent
permitted by applicable law, become the property of Parent, free and clear of
all claims or interest of any Person previously entitled thereto.
Notwithstanding the foregoing, none of Parent, the Company, the Surviving
Corporation nor the Disbursing Agent shall be liable for any merger
consideration properly delivered to a public official pursuant to any applicable
abandoned property, escheat or other similar law.

       2.5 Withholdings; Net Payments. Notwithstanding anything in this
Agreement to the contrary, any amount paid to Stockholders or Option Holders
pursuant to this Agreement that are not United States Persons, as defined in
Section 7701(a)(30) of the Internal Revenue Code of 1986, as amended, and the
rules and regulations promulgated thereunder (the "Code"), shall be net of all
applicable Federal, state and local withholding Taxes, as determined by the
Surviving Corporation. Parent or Surviving Corporation shall withhold and remit,
and the Parent shall cause the Disbursing Agent to withhold and remit, to the
appropriate taxing authority all such withholding Taxes due in connection with
the payments made by it, and such remittance shall be deemed a payment of
amounts owed to any Person entitled to payment pursuant to this Agreement. Any
payment to non-employee Option Holders shall be at the minimum withholding
amount required by Applicable Laws. Prior to the Effective Time, the Company
shall use its reasonable best efforts to take such actions as shall be necessary
to allow Parent or the Disbursing Agent to comply with this Section 2.5.

       2.6 Dissenting Shares.

       (a) Notwithstanding anything contained in this Agreement to the contrary,
shares of Company Common Stock that are held by any Stockholder who has not
voted in favor of the Merger or consented thereto in writing, and who has
demanded appraisal rights in accordance with the VSCA (the "Dissenting Shares")
shall not be converted into the right to receive the merger consideration, but
shall become the right to receive such consideration as may be determined to be
due in respect of such Dissenting Shares pursuant to the VSCA; provided,
however, that any holder of Dissenting Shares who shall have failed to perfect
or shall have withdrawn or lost his or her rights to appraisal of such
Dissenting Shares, in each case under the VSCA, shall forfeit the right to
appraisal of such Dissenting Shares, and such Dissenting Shares shall be deemed
to have been converted into the right to receive, as of the Effective Time, cash
in an amount equal to the product of the number of such Dissenting Shares
multiplied by the Per Share Merger Consideration, without interest.

       (b) The Company shall give Parent (i) prompt notice of any demands for
appraisal, and any withdrawals of such demands, received by the Company and any
other related instruments served pursuant to the VSCA and received by the
Company, and (ii) the opportunity to direct all negotiations and proceedings
with respect to demands for appraisal under the VSCA. The Company shall not,
except with the prior written consent of Parent, make any payment with respect
to any demands for appraisal or offer to settle or settle any such demands.


                                      A-6


                                  ARTICLE III

                         REPRESENTATIONS AND WARRANTIES
                                 OF THE COMPANY

       The Company represents and warrants to Parent and Merger Sub as follows:

       3.1 Organization and Qualification; Subsidiaries.

       (a) The Company and each Subsidiary of the Company (collectively, the
"Company Subsidiaries") is a corporation, partnership or other legal entity duly
incorporated or organized, validly existing and in good standing under the laws
of its jurisdiction of incorporation or organization, has requisite power and
authority and governmental approvals to own, lease and operate its properties
and to carry on its business as currently conducted. The Company and each
Company Subsidiary is duly qualified or licensed to do business and is in good
standing in each jurisdiction in which the ownership or leasing of its property
or the conduct of its business requires such qualification or licensing, except
where the failure to be so qualified or licensed or in good standing would not,
individually or in the aggregate, have a Company Material Adverse Effect.
"Company Material Adverse Effect," as used in this Agreement, shall mean any
change, effect, event or occurrence that is materially adverse to the condition
(financial or otherwise), assets, properties, business or operations of the
Company and the Company Subsidiaries, taken as a whole. The copies of the
Articles of Incorporation and Bylaws (or equivalent organizational documents) of
the Company and each Company Subsidiary previously delivered to Parent or its
counsel are complete and correct.

       (b) Schedule 3.1 sets forth the name, type of entity, jurisdiction, date
of incorporation, formation or organization, the officers and directors, the
authorized stock, partnership capital or equivalent ownership interests, the
number and type of issued and outstanding shares of capital stock, partnership
interests or similar ownership interests, the current owners of the equity and
their respective ownership interests therein of each Company Subsidiary and each
other corporation or entity in which the Company directly or indirectly owns or
has the power to vote capital stock or other ownership interests, and the
jurisdictions in which each entity is qualified to do business as a foreign
corporation or other foreign entity, each as of the date of the Agreement. The
Company does not directly or indirectly own any interest in any other person or
entity. The respective minute books, or comparable records, of the Company and
each of the Company Subsidiaries contain true and complete records of all
meetings and consents in lieu of meetings of their Boards of Directors or
similar governing bodies (and any committees thereof) and of their stockholders
(or partners or members) since the times of their respective incorporation or
formation, and accurately reflect all transactions referred to in such minutes
and consents in lieu of meeting in all material respects. The stock books (or
analogous ownership records) of the Company and each of the Company Subsidiaries
are true and complete. True and complete copies of all of the foregoing, have

of a kind required by GAAP to be set forth on a financial statement or in the
notes thereto ("Liabilities"), that were not fully and adequately reflected or
reserved against on the balance sheet or described in the notes to the Audited
Financials, including, without limitation, those relating to environmental and
occupational safety and health matters, that, alone or in the aggregate, could
result in claims against, obligations of or liabilities to the Company or any of
the Company Subsidiaries which are reasonably likely to have a Company Material
Adverse Effect. Except as set forth on Schedule 3.6, neither the Company nor any

Company Material Adverse Effect, and neither the Company nor any of the Company
Subsidiaries has any Knowledge of any such change that is threatened, nor has
there been any damage, destruction or loss affecting the assets, properties,

are material to or necessary for the lawful conduct of the businesses of the
Company and each of the Company Subsidiaries or material to or necessary for the

Material Contracts, in each case as amended to date. All Material Contracts have
been delivered to, or, to the extent not requested to be delivered, have been

       (b) Except as set forth on Schedule 3.15, each Material Contract
constitutes a valid and binding obligation of the Company or a Company
Subsidiary, as the case may be, is in full force and effect and is enforceable
against the Company or a Company Subsidiary, as the case may be, in accordance
with its terms, except to the extent such enforceability may be limited by (i)
bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or
other laws relating to or affecting creditors' rights, and (ii) general
principles of equity (regardless of whether such enforceability is considered in
a proceeding in equity or at law). The Company and each of the Company
Subsidiaries have either paid in full all amounts due thereunder which are due
and payable or accrued in accordance with GAAP, all amounts due to others
thereunder (and have properly recognized revenues due from others thereunder),
and have satisfied in full or accrued all of their liabilities and obligations
thereunder which are due and payable, except amounts or liabilities disputed in
good faith by the Company or any of the Company Subsidiaries for which adequate
reserves have been set aside. Neither the Company nor any Company Subsidiary is
in default under any Material Contract, nor to the Knowledge of the Company and
the Company Subsidiaries, does any condition exist that, with notice or lapse of
time or both, would constitute a default thereunder. To the Knowledge of the
Company and the Company Subsidiaries, no other party to any such Material
Contract is in default thereunder, nor does any condition exist that with notice
or lapse of time or both would constitute a default thereunder. Neither the
Company nor any of the Company Subsidiaries has Knowledge that any person

Material Contract before its stated term, if any. Except as set forth on
Schedule 3.15, neither the Company nor any of the Company Subsidiaries has any
Knowledge of a claim for non-performance of any Material Contract, pending or
threatened, by any Governmental Body. There are no pending renegotiations of,
attempts to renegotiate or outstanding rights to renegotiate any material
amounts paid or payable under any Material Contract, and no person has made a
written demand for any such renegotiation. Except as separately identified on
Schedule 3.15, no approval or consent of any person is needed in order that the
contracts and other agreements set forth or required to be set forth on Schedule
3.15 or on any other Schedule


                                      A-13


continue in full force and effect following the consummation of the transactions
contemplated by this Agreement.

       3.16 Taxes. Except as set forth in Schedule 3.16:

       (a) Filing of Tax Returns. The Company and each Company Subsidiary have
timely filed, or have had timely filed on their behalf, with the appropriate
Taxing authorities all Tax Returns in respect of Taxes required to be filed by
them. The Tax Returns filed (including any amendments thereof) are complete and
accurate in all material respects. The Company and each Company Subsidiary have
not requested any extension of time within which to file any Tax Return in
respect of any Taxes, which Tax Return has not since been filed in a timely
manner. To the Knowledge of the Company, no claim has ever been made by any
Taxing authority in a jurisdiction where the Company or any Company Subsidiary
does not file Tax Returns, or has Tax Returns filed on their behalf, that they
are or may be subject to taxation by that jurisdiction, or liable for Taxes
owing to that jurisdiction. Schedule 3.16 lists all federal, state, local and
foreign income Tax Returns filed (including, but not limited to, income,
franchise, capital, net worth, sales, use, payroll, excise and ad valorem tax)
with respect to the Company and each Company Subsidiary for taxable periods
ended on or after December 31, 1997. The Company and each Company Subsidiary
have delivered to the Parent complete, correct and accurate copies of their
foreign, federal, state and local Tax Returns, examination reports and
statements of deficiencies assessed against or agreed to by the Company and each
Company Subsidiary for the years ended December 31, 1997, 1998, 1999 and 2000.


       (b) Payment of Taxes. All Taxes owed by the Company and each Company
Subsidiary (whether or not shown as due on any Tax Returns) have been paid in
full or adequate reserves on their respective books and/or records have been
established. The Company and each Company Subsidiary have withheld and paid all
Taxes required to have been withheld and paid in connection with amounts paid or
owing to any employee, independent contractor, creditor, stockholder, or other
third party. The Company has made all required estimated Tax payments sufficient
to avoid any underpayment penalties. The unpaid Taxes of the Company and each
Company Subsidiary (A) do not, as of the Closing Date, exceed the reserve for
Tax liability (rather than any reserve for deferred Taxes established to reflect
the timing differences between book and Tax income) set forth on the face of the
Company's and each Company Subsidiary's most recent balance sheets (rather than
any notes thereto) and (B) do not exceed that reserve as adjusted for the
passage of time through the Closing Date in accordance with the past custom and
practice of the Company and each Company Subsidiary in filing, or having filed
on their behalf, their Tax Returns. The charges, accruals and reserves on the
books of the Company and each Company Subsidiary in respect of any liability for
Taxes (x) based on or measured by net income for any years not finally
determined, (y) with respect to which the applicable statute of limitations has
not expired or (z) that has been previously deferred, are adequate to satisfy
any assessment for such Taxes for any such years.

       (c) Audits, Investigations or Claims. There is no dispute or claim which
has not been resolved concerning any Tax liability of the Company or any Company
Subsidiary either (A) claimed or raised by any Taxing authority in writing or
(B) as to which any of the


                                      A-14


directors and officers (and employees responsible for Tax matters) of the
Company or any Company Subsidiary has knowledge based upon personal contact with
any agent of such Taxing authority. Audits of foreign, federal, state and local
Tax Returns by the relevant Taxing authorities are currently ongoing where
indicated for the periods set forth on Schedule 3.16 and, except as set forth in
such Schedule, the Company and each Company Subsidiary have not been notified in
writing that any of these Taxing authorities intends to audit a Tax Return for
any other period. Neither the Company nor any Company Subsidiary has executed
any outstanding waivers or consents regarding the application of the statute of
limitations with respect to any Taxes or Tax Returns.

       (d) Lien. There are no encumbrances for Taxes (other than for current
Taxes not yet due and payable) on any assets of the Company or any Company
Subsidiary.

       (e) Tax Elections. The Company and each Company Subsidiary (i) have not
agreed, or are required, to make any adjustment under Section 481(a) of the Code
by reason of a change in accounting method or otherwise; (ii) have not made an
election pursuant to Code Sections 338 or 336(e) or the regulations thereunder
or any comparable provisions of any foreign or state or local income tax law;
(iii) are not subject to any constructive elections under Code Section 338 or
the regulations thereunder; (iv) have not made any payments, are obligated to
make any payments, or are a party to any agreement that under certain

under ss.280G and ss.162(m) of the Code; and (v) have not made any of the
foregoing elections or are required to apply any of the foregoing rules under
any comparable state or local income Tax provision.

       (f) Prior Affiliated Groups. The Company and each Company Subsidiary (A)
have never been a member of an affiliated group of corporations within the
meaning of Section 1504 of the Code (other than a group the common parent of
which was the Company) and (B) do not have any liability for the Taxes of any
person (other than any of the Company and the Company Subsidiaries) under Treas.
Reg. ss.1502-6 (or any similar provision of state, local or foreign law), as a
transferee or successor, by contract or otherwise. Neither the Company nor any
Company Subsidiary is a successor to any other person by way of merger,
reorganization or similar transaction.

       (g) Tax Sharing Agreements. Neither the Company nor any Company
Subsidiary is a party to any Tax allocation, indemnity or sharing or similar
agreement.

       (h) Net Operating Losses and General Business Credit. As of September 30,
2001, the net operating loss carryforward of the Company for federal income Tax
purposes was not less than $13,100,000, and, as of December 31, 2000, the
General Business Credit carryforward was not less than $170,792, and except as
set forth on Schedule 3.16, to the Knowledge of the Company, the Company is not
subject to any limitations, under Sections 382, 383 and 384 of the Code and
restrictions under the consolidated return regulations pursuant to Section 1502
of the Code or provisions of state laws affecting such net operating loss
carryforwards for state income tax or state franchise tax purposes, on its
ability to use the net operating loss carryforward other than those under the
Code or otherwise that may arise as a result of the Transactions.


                                      A-15


       (i) Section 355. Neither the Company nor any Company Subsidiary has
distributed the stock of a "controlled corporation" (within the meaning of that
term as used in Section 355(a) of the Code) in a transaction subject to Section
355 of the Code within the past two years.

       (j) Partnerships. Neither the Company nor any Company Subsidiary owns an
interest in a partnership for Tax purposes.

       (k) Neither the Company nor any Company Subsidiary will be required to
include any item of income in, or exclude any item of deduction from, taxable
income for any taxable period (or portion thereof) ending after the Closing Date
as a result of any: (A) change in any method of accounting for a taxable period
ending on or prior to the Closing Date under Code Section 481(c) (or any

       (a) Neither the Company nor any Company Subsidiary owns, or has owned,
any real property or any interest in any real property.

       (b) Schedule 3.18 sets forth a true, correct and complete list of all
leases, subleases, licenses and other agreements (collectively, the "Real
Property Leases") under which the Company or any Company Subsidiary uses or
occupies or has the right or obligation to use or occupy or pay rent or other
fees for use thereof, now or in the future, any real property (the land,
buildings and other improvements covered by the Real Property Leases being
hereinafter referred to as the "Leased Real Property") which Schedule includes
the true, correct and complete property address, square footage and lease
expiration date of each respective Real Property Lease, together with details of
any security deposit and other prepaid amounts owing in respect of each Real
Property Lease. The Company has heretofore delivered or made available to Parent
true, correct and complete copies of all Real Property Leases, including all
modifications, amendments and supplements thereto. Each Real Property Lease is
valid, binding and in full force and effect, and as of the Closing, all amounts
owing pursuant to the Real Property Leases will have been paid in full. Neither
the Company nor any Company Subsidiary has received notice of, or to the
Knowledge of the Company or the Company Subsidiaries, have there been any,
threatened defaults by any landlord or tenant under any Real Property Lease or
under any subordinate transfer under a Real Property Lease. All required
consents, approvals or authorization of, filing with, or notice to, any party to
any of the Real Property Leases in connection with the Transactions have been
completed. All of the land, buildings, structures, plants, facilities and other
improvements used by the Company and any Company Subsidiary in the conduct of
their respective businesses are included in the Leased Real Property.

       (c) Except as set forth on Schedule 3.18, neither the Company nor any

nor any Company Subsidiary has received notice that there are any pending, or to
the Knowledge of the Company and the Company Subsidiaries, have there been any,
threatened requests, applications or proceedings to alter or restrict any zoning
or other use restrictions applicable to the Leased Real Property, any
improvements thereon or any portion thereof. There are no adverse parties in
possession of the Leased Real Property or any portion or portions thereof, and
on the Closing Date the Company and the Company Subsidiaries' interests in the
Leased Real Property will be free and clear of any and all leases, licenses,
occupants or tenants except as set forth in Schedule 3.18.

       (d) All buildings, structures, fixtures and other improvements on the
Leased Real Property are in good repair, free of defects (latent or patent), and
fit for the uses to which they are currently devoted. All such buildings,
structures, fixtures and improvements on the Leased Real Property conform to all
Applicable Laws. The buildings, structures, fixtures and improvements on each
parcel of the Leased Real Property lie entirely within the boundaries of

Real Property.

       (e) None of the Leased Real Property is subject to any agreement or other
restriction of any nature whatsoever (recorded or unrecorded) preventing or
limiting Company's or the Company Subsidiary's right to convey or to use it.

       (f) The Leased Real Property has direct and unobstructed access to

intended to be devoted.

of all claims (exclusive of claims under medical and dental policies) made by
the Company or any of the Company Subsidiaries during the Company's past two
fiscal years and the amount paid out under each policy with respect to such
claims. Neither the Company nor any of the Company Subsidiaries has any
Knowledge of any facts or of the occurrence of any event that is reasonably
likely to form the basis for any material claim against the Company or any of
the Company Subsidiaries which will not be fully covered by such policies.

corporation or other person of which any officer or director of the Company or
any of the Company Subsidiaries, or an immediate family member of the foregoing,

investigating or examining party, during such period, with all such information
and copies of such documents as such representatives may reasonably request,
shall make available its officers and employees (and those of its Subsidiaries)
as such representatives may reasonably request, and shall cause its officers and

necessary in connection with the pursuit or defense of a claim, (ii) such
information was known by such party prior to such disclosure or was thereafter
developed or obtained by such party independent of such disclosure, (iii) such
party received such information on a non-confidential basis from a source, other
than the other party, which is not known by such party to be bound by a
confidentiality obligation with respect thereto or (iv) such information becomes
generally available to the public or is otherwise no longer confidential. Prior
to any disclosure of information pursuant to the exception in clause (i) of the
preceding sentence, the party intending to disclose the same shall so notify the
party which provided the same to the extent practicable in order that such party
may seek a protective order or other appropriate remedy should it choose to do
so.

       5.6 Notification of Certain Matters. The Company shall give prompt notice
to Parent if any of the following occurs after the date of this Agreement: (i)

with notice or lapse of time or both would become a default, under any Material
Contract; (ii) receipt of any notice or other communication in writing from any
person alleging that the consent of such person is or may be required in
connection with the transactions contemplated by this Agreement, other than a
consent disclosed pursuant to Section 3.13 above or not required to be disclosed

communication from any Governmental Authority (including, but not limited to,
the NASD or any securities exchange) in connection with the transactions

material respect; (v) the commencement or threat of any material litigation
involving or affecting the Company or any Company Subsidiary, or any of their
respective properties or assets; (vi) the occurrence or non-occurrence of any
fact or event that causes or is reasonably likely to cause a breach by the
Company of any provision of this Agreement, and (vii) the occurrence of any
event that, had it occurred prior to the date of this Agreement without any

Adverse Effect.


                                      A-27


       5.7 Non-Solicitation.

       (a) Neither the Company nor any Company Subsidiary, nor any of their
respective officers, directors, employees, agents, affiliates, accountants,
counsel, investment bankers, financial advisors or other representatives
(collectively, "Representatives") shall, (i) directly or indirectly, initiate,
solicit or encourage, or take any action to facilitate the making of, any
Acquisition Proposal, or (ii) directly or indirectly engage in any discussions
or negotiations with, or provide any information or data to, or afford any
access to the properties, books or records of the Company or any Company
Subsidiary to, or otherwise assist, facilitate or encourage, any person (other
than Parent or any affiliate or associate thereof) relating to any Acquisition
Proposal; provided, however, that at any time prior to the Company Stockholders
Meeting, the Company may, in response to a Superior Proposal (as defined below)
which was not solicited by it and which did not otherwise result from a breach
of this Section 5.7(a), and subject to providing prior written notice of its
decision to take such action to Parent (the "Notice") and compliance with
Section 5.7(c), following delivery of the Notice (x) furnish information with
respect to the Company, or the Company Subsidiaries to any person making a
Superior Proposal pursuant to a customary confidentiality agreement and (y)
participate in discussions and negotiations regarding such Superior Proposal
but, in each case, only if the Company's Board of Directors determines, after
consultation with its outside counsel, that failure to furnish such information
or to participate in such discussions or negotiations would be inconsistent with
the compliance by the Company's Board of Directors with its fiduciary duties to
stockholders imposed by Applicable Law. The Company shall keep Parent apprised
of any such discussions and negotiations promptly after they occur.

       (b) Except as set forth below, neither the Board of Directors of the
Company, nor any committee thereof, shall (x) withdraw or modify, or propose to
withdraw or modify, in a manner adverse to Parent, the Board of Directors'
approval or recommendation of the Merger or this Agreement, (y) approve any
letter of intent, agreement in principle, acquisition agreement or similar
agreement (other than a confidentiality agreement in connection with a Superior
Proposal which is executed by the Company in accordance with Section 5.7(a))
relating to any Acquisition Proposal (each, an "Acquisition Agreement"), or (z)
approve or recommend, or propose to approve or recommend, any Acquisition
Proposal. Notwithstanding the foregoing, in response to a Superior Proposal
which was not solicited by the Company, and which did not otherwise result from
a breach of Section 5.7(a), the Board of Directors of the Company may terminate
this Agreement pursuant to and subject to the terms of Section 7.1(g) and,
concurrently with such termination, cause the Company, to execute an Acquisition
Agreement with respect to a Superior Proposal, but only if the Company's Board
of Directors determines, after consultation with its outside counsel, that
failure to terminate this Merger Agreement and accept the Superior Proposal
would be inconsistent with the compliance by the Company's Board of Directors
with its fiduciary duties to stockholders imposed by Applicable Law.

       (c) The Company promptly shall advise the Parent orally and in writing of
any Acquisition Proposal with respect to or that could reasonably be expected to
lead to any Acquisition Proposal, the identity of the person making any such
Acquisition Proposal and the


                                      A-28


material terms of any such Acquisition Proposal. The Company shall keep the
Parent fully informed of the status and material terms of any such Acquisition
Proposal.

       (d) The Company and each Company Subsidiary and each of their
Representatives shall immediately cease and cause to be terminated all existing
discussions and negotiations, if any, with any other persons conducted
heretofore with respect to any Acquisition Proposal.

       For purposes of this Agreement, an "Acquisition Proposal" means any
inquiry, proposal or offer from any person relating to (i) any direct or
indirect acquisition or purchase of a business that constitutes 50% or more of
the net revenues, net income or assets of the Company and the Company
Subsidiaries, taken as a whole, or 50% or more of the common stock or voting
power (or of securities or rights convertible into or exercisable for such
common stock or voting power) of the Company, (ii) any tender offer or exchange
offer that if consummated would result in any person beneficially owning 50% or
more of the common stock or voting power (or of securities or rights convertible
into or exercisable for such common stock or voting power) of the Company, or
(iii) any merger, consolidation, business combination, recapitalization,
liquidation, dissolution or similar transaction involving the Company, or any of
its Subsidiaries that constitutes 50% or more of the net revenues, net income or
assets of the Company, and its Subsidiaries taken as a whole, in each case other
than the transactions contemplated by this Agreement. Each of the transactions
referred to in clauses (i) - (iii) of the foregoing definition of Acquisition
Proposal, other than the Merger proposed by this Agreement, is referred to
herein as an "Acquisition Transaction."

       For purposes of this Agreement, a "Superior Proposal" means any written
proposal made by a third party to acquire, directly or indirectly, including
pursuant to a tender offer, exchange offer, merger, consolidation, business
combination, recapitalization, liquidation, dissolution or similar transaction,
for consideration consisting of cash and/or securities, more than 50% of the
combined voting power of the shares of Company Common Stock then outstanding or
more than 50% of the assets of the Company and its Subsidiaries, taken together,
with respect to which (x) the Board of Directors of the Company determines in
its good faith judgment (based on the advice of a financial advisor of
nationally recognized reputation (the "Financial Advisor") and such other
matters as the Board of Directors of the Company deems relevant, which shall
include without limitation the likelihood of consummation and the trading market
and liquidity of any securities offered in connection with the Superior
Proposal) that the terms of the proposal are more favorable to the Company's
stockholders from a financial point of view as compared to the Merger, and (y)
if the proposal (1) is subject to a financing condition or (2) involves
consideration that is not entirely cash or does not permit stockholders to
receive the payment of the offered consideration in respect of all shares at the
same time, the Company's Board of Directors has been furnished with a written
opinion of the Financial Advisor to the effect that (in the case of clause (1))
the proposal is readily financeable and (in the case of clause (2)) that such
proposal provides a higher value per share than the consideration per share
pursuant to the Merger.


                                      A-29


       5.8 Further Assurances. At any time and from time to time after the

benefits earned or accrued under the Benefit Plans of the Company and each
Company Subsidiary, except as may otherwise be agreed to in writing by the
parties thereto.

       (b) To the extent that any individual employed by the Company or any
Company Subsidiary immediately prior to the Closing Date (each, an "Affected
Employee") becomes a participant in any Benefit Plan maintained by Parent or any
Subsidiary or Affiliate of Parent, Parent shall, or shall cause such Subsidiary
or Affiliate of Parent to, give such Affected Employee full credit, solely for
the purposes of determining eligibility and vesting under such Benefit Plan, for
such Affected Employee's service with the Company or any Company Subsidiary, to
the extent such service was recognized by the Company or any Company Subsidiary
immediately prior to the Closing Date. Notwithstanding the foregoing, with
respect to any Benefit Plan maintained by Parent or any Subsidiary or Affiliate
of Parent which constitutes a pension or retirement benefit plan, the entry date
for Affected Employees who otherwise meet the eligibility criteria of such
Benefit Plan shall be the first day of the calendar quarter immediately
following the later of (i) the Closing, and (ii) receipt by Parent from the
Company of all data deemed necessary by Parent regarding such Affected
Employees' hours of service with the Company and each Company Subsidiary. Parent
shall recognize each Affected Employee's hours of service worked for the Company
or any Company Subsidiary in the calculation of retirement plan eligibility and
service according to computation rules for similarly situated Parent employees.

       (c) After the Closing, Parent shall, or shall cause the Surviving
Corporation and its Subsidiaries to, provide Affected Employees with benefits
that are no less favorable in the aggregate than benefits provided to similarly
situated employees of Parent and its Subsidiaries and Affiliates.

       (d) Prior to the Closing Date, the Board of Directors of the Company
shall adopt resolutions (certified copies of which shall be delivered to Parent)
terminating each Benefit Plan maintained by the Company or any Company
Subsidiary which constitutes an employee pension benefit plan within the meaning
of Section 3(2) of ERISA effective immediately prior to the Closing.

the SEC with respect to the Proxy Statement and of any requests by the SEC for
any amendment or supplement thereto or for additional information and shall

its counsel the opportunity to review the Proxy Statement prior to its being

Subsidiary agrees to use its reasonable best efforts, after consultation with
the other parties hereto to respond promptly to all such comments of and
requests by the SEC. As promptly as practicable after the Proxy Statement has
been cleared by the SEC, the Company shall mail the Proxy Statement to the
stockholders of the Company. Prior to the date of approval of the Merger by the
Company's stockholders, each of the Company, Parent and Merger Subsidiary shall
correct promptly any information provided by it to be used specifically in the
Proxy Statement that shall have become false or misleading in any material
respect and the Company shall take all steps necessary to file with the SEC and
cleared by the SEC any amendment or supplement to the Proxy Statement so as to
correct the same and to cause the Proxy Statement as so corrected to be
disseminated to the stockholders of the Company, in each case to the extent
required by applicable law.

agreements with the Persons listed on Schedule 5.13(c), providing for the
termination of any Out-of-the-Money Options and the exercise of any In-the-Money
Options held by such Persons, in each case, as of the Effective Time, and (ii)
designate an exercise period under the Company's 1995 Stock Option Plan ending
not more than 10 days prior to the Closing Date. The Company shall promptly
notify Parent of any failure or prospective failure to obtain any such consents,
and shall use its reasonable best efforts to take all action reasonably
requested by Parent to attempt to obtain such consents.

       5.14 Anti-takeover Statutes. If, notwithstanding the actions taken
pursuant to Section 3.5, any "fair price," "moratorium," "control share
acquisition" or other form of anti-takeover statute is or shall become
applicable to the Merger or Transactions contemplated hereby, the Company and
the members of the Board of Directors, to the extent permitted by Applicable
Laws, shall grant such approvals and take such actions as are necessary and are
reasonably practicable to be granted or taken so that the Merger and other

$150,000), if (i) Parent terminates this Agreement pursuant to Sections 7.1(e),
(h) or (j), or (ii) the Company terminates this Agreement pursuant to Section

any expenses paid pursuant to the first sentence of this Section 7.3(c))
(collectively, the "Termination Payment"), and (B) the product of the

Acquisition Consideration" means the aggregate consideration paid by a third
party in connection with an Acquisition Transaction. Such Additional Fee shall
be paid by the Company not later than five (5) Business Days after the closing

7.3 are an integral part of the transactions contemplated by this Agreement, and
that, without these agreements, neither Parent nor the Company would not enter
into this Agreement. Accordingly, if either party fails to promptly pay any
amounts owing pursuant to this Section 7.3 when due, then the party from whom
such payment is due shall in addition thereto pay to the other party all costs
and expenses (including fees and disbursements of counsel) incurred in
collecting such amounts, together with interest on such amounts (or any unpaid
portion thereof) from the date such payment was required to be made until the
date such payment is received by the party entitled to such payment hereunder at
the prime rate of Chase Manhattan as in effect from time to time during such
period.

The Board of Directors
Infodata Systems, Inc.
12150 Monument Drive
Fairfax, VA  22033-4063

Members of the Board:

You have requested our opinion as to the fairness, from a financial point of
view, to the holders of common stock, par value $0.03 per share (the "Company
Common Stock") of Infodata Systems, Inc. ("Infodata" or the "Company") of the
consideration to be received by such holders pursuant to the terms of the draft
Agreement and Plan of Merger (the "Agreement"), dated December 13, 2001, by and
among the Company, Science Applications International Corporation ("Parent") and
Info Acquisition Corp., a wholly-owned subsidiary of Parent ("Merger Sub"). As
more fully described in the Agreement, (i) Merger Sub will be merged with and
into Infodata (the "Merger") and (ii) each outstanding share of common stock of
Infodata ("Shares") will be converted into the right to receive $1.00 per share
in cash (the Per Share Merger Consideration).

The Agreement further provides that each holder of an Infodata stock option with
an exercise price less than $1.00 per share (the "In-the-Money Options") will
receive a cash payment equal to the excess of (a) the Per Share Merger
Consideration over (b) such exercise price per share of Company Common Stock
subject to such In-the-Money Option multiplied by (c) the number of shares of
Company Common Stock subject to such In-the-Money Option.

In arriving at our opinion, we interviewed management regarding the business
prospects, financial outlook and operating plans of the Company, and reviewed
certain publicly available business and financial information relating to the
Company for recent years and

                                      B-1


interim periods to date. We also reviewed certain internal financial and
operating information, including financial forecasts and projections that were
provided to us by the Company taking into account the growth prospects of the
Company and the marketplaces in which Infodata is involved. Additionally, we
reviewed a copy of the Agreement.

We also compared certain financial data from the Company to similar data for
certain other companies, the securities of which are publicly traded, which we
believe are comparable to the Company, and we considered the financial terms of
recent acquisitions and business combination transactions in the information
technology industry specifically.

We utilized a discounted cash flow analysis to analyze the present value of the
future cash flow streams that the Company is expecting to generate. In addition,
we reviewed certain publicly available information concerning the trading of,
and the trading market for, the Shares, including without limitation the average
trading price of Infodata over the past three (3) months. We have also
considered the limited trading volume and public float of the Shares in
evaluating the Per Share Merger Consideration. We have also reviewed the
premiums paid in comparable merger and acquisition transactions in relation to
the premium represented by the Per Share Merger Consideration to the market
price of the shares at different times prior to the execution of the Agreement.
We have also performed such other studies, analyses and investigations as we
considered appropriate.

In soliciting offers, we marketed the Company to a broad spectrum of potential
acquirers, including both strategic and financial buyers in the United States
and abroad. The marketing process was conducted over a twelve (12) month period.
During the marketing period, we contacted several hundred companies and provided
many with the confidential offering memorandum. Multiple potential buyers were
provided the opportunity to meet with management, review detailed financial and
operating information about the Company, and perform due diligence.

In our review and analysis and in formulating our opinion, we have assumed and
relied upon the accuracy and completeness of all of the financial and other
information provided to us or publicly available, and we have not attempted to
independently verify any of such information. We have assumed, with your
consent, that the financial forecasts and projections provided to us by the
Company were prepared in good faith and on the basis reflecting the best
currently available judgments and estimates of the Company's management. We have
also assumed that there have been no material changes in the Company's assets,
financial condition, results of operations, business or prospects since the most
recent financial statements made available to us. In addition, we have not
conducted a physical inspection of the properties and facilities of the Company
and have not made or obtained an independent valuation or appraisal of the
assets or liabilities (contingent or otherwise) of the Company. Our opinion is
necessarily based on the economic and market conditions and other circumstances
as they exist and are evaluated by us on the date hereof. Although subsequent
developments may affect this opinion, we have not assumed any obligation to
update, revise or reaffirm this opinion.

                                      B-2


We have relied on advice of the counsel and independent accountants to the
Company as to all legal and financial reporting matters with respect to the
Company, the Merger and the Agreement. We have assumed that the Merger will be
consummated in a manner that complies in all respects with the applicable
provisions of the Securities Exchange Act of 1934, as amended, and all other
applicable federal and state statutes, rules and regulations. We have further
assumed with your consent that the Merger will be consummated in accordance with
the terms described in the Agreement, without any further material amendments
thereto, and without waiver by the Company of any of the conditions to Parent's
and Merger Sub's obligations thereunder.

As part of our investment banking services, we engage in the valuation of
businesses and their securities in connection with mergers and acquisitions
involving both listed and unlisted companies and their associated securities, in
the information technology services and other technology related industries. We
have acted as financial advisor to the Company in connection with the Merger and
will receive a fee for our services upon consummation of the Merger. We will
also receive a fee from the Company for rendering this opinion. The fee rendered
for this opinion is not contingent upon the results of the Merger.

It is understood that this letter is for the benefit and use of the Board of
Directors of the Company in its consideration of the Agreement and may not be
used by any other person, used for any other purpose or reproduced,
disseminated, quoted or referred to at any time, in any manner or for any
purpose without our prior written consent or as required under applicable law or
by the Securities and Exchange Commission (SEC). This letter may be included in
the proxy statement you file with the SEC and you distribute to your
shareholders with respect to the Merger. This letter does not constitute a
recommendation to any shareholder to vote in favor of the Merger and should not
be relied upon by any shareholder as such a recommendation. Further, this
opinion addresses only the financial fairness as of the date hereof of the Per
Share Merger Consideration to be received by the shareholders of the Company,
and it does not address any other aspect of the Merger.

Based upon and subject to the foregoing, including the various assumptions and
limitations set forth herein, it is our opinion that the Per Share Merger
Consideration to be received by the shareholders of the Company pursuant to the
Agreement is fair from a financial point of view to such shareholders as of the
date hereof.

Very truly yours,



INVESTEC PMG CAPITAL

                                   APPENDIX C

                                   Article 15.

                               Dissenters' Rights.


ss. 13.1-729. Definitions.

In this article:

         "Corporation" means the issuer of the shares held by a dissenter before
the corporate action, except that (i) with respect to a merger, "corporation"
means the surviving domestic or foreign corporation or limited liability company
by merger of that issuer, and (ii) with respect to a share exchange,
"corporation" means the acquiring corporation by share exchange, rather than the
issuer, if the plan of share exchange places the responsibility for dissenters'
rights on the acquiring corporation.

         "Dissenter" means a shareholder who is entitled to dissent from
corporate action under ss. 13.1-730 and who exercises that right when and in the
manner required by sections 13.1-732 through 13.1-739.

         "Fair value," with respect to a dissenter's shares, means the value of
the shares immediately before the effectuation of the corporate action to which
the dissenter objects, excluding any appreciation or depreciation in
anticipation of the corporate action unless exclusion would be inequitable.

         "Interest" means interest from the effective date of the corporate
action until the date of payment, at the average rate currently paid by the
corporation on its principal bank loans or, if none, at a rate that is fair and
equitable under all the circumstances.

         "Record shareholder" means the person in whose name shares are
registered in the records of a corporation or the beneficial owner of shares to
the extent of the rights granted by a nominee certificate on file with a
corporation.

         "Beneficial shareholder" means the person who is a beneficial owner of
shares held by a nominee as the record shareholder.

         "Shareholder" means the record shareholder or the beneficial
shareholder.

         ss. 13.1-730. Right to dissent.

         A. A shareholder is entitled to dissent from, and obtain payment of the
fair value of his shares in the event of, any of the following corporate
actions:

         1. Consummation of a plan of merger to which the corporation is a party
(i) if shareholder approval is required for the merger by ss. 13.1-718 or the
articles of incorporation and the shareholder is entitled to vote on the merger
or (ii) if the corporation is a subsidiary that is merged with its parent under
ss. 13.1-719;

         2. Consummation of a plan of share exchange to which the corporation is
a party as the corporation whose shares will be acquired, if the shareholder is
entitled to vote on the plan;

                                      C-1

         3. Consummation of a sale or exchange of all, or substantially all, of
the property of the corporation if the shareholder was entitled to vote on the
sale or exchange or if the sale or exchange was in furtherance of a dissolution
on which the shareholder was entitled to vote, provided that such dissenter's
rights shall not apply in the case of (i) a sale or exchange pursuant to court
order, or (ii) a sale for cash pursuant to a plan by which all or substantially
all of the net proceeds of the sale will be distributed to the shareholders
within one year after the date of sale;

         4. Any corporate action taken pursuant to a shareholder vote to the
extent the articles of incorporation, bylaws, or a resolution of the board of
directors provides that voting or nonvoting shareholders are entitled to dissent
and obtain payment for their shares.

         B. A shareholder entitled to dissent and obtain payment for his shares
under this article may not challenge the corporate action creating his
entitlement unless the action is unlawful or fraudulent with respect to the
shareholder or the corporation.

         C. Notwithstanding any other provision of this article, with respect to
a plan of merger or share exchange or a sale or exchange of property there shall
be no right of dissent in favor of holders of shares of any class or series
which, at the record date fixed to determine the shareholders entitled to
receive notice of and to vote at the meeting at which the plan of merger or
share exchange or the sale or exchange of property is to be acted on, were (i)
listed on a national securities exchange or on the National Association of
Securities Dealers Automated Quotation System (NASDAQ) or (ii) held by at least
2,000 record shareholders, unless in either case:

         1. The articles of incorporation of the corporation issuing such shares
provide otherwise;

         2. In the case of a plan of merger or share exchange, the holders of
the class or series are required under the plan of merger or share exchange to
accept for such shares anything except:

         a. Cash;

         b. Shares or membership interests, or shares or membership interests
and cash in lieu of fractional shares (i) of the surviving or acquiring
corporation or limited liability company or (ii) of any other corporation or
limited liability company which, at the record date fixed to determine the
shareholders entitled to receive notice of and to vote at the meeting at which
the plan of merger or share exchange is to be acted on, were either listed
subject to notice of issuance on a national securities exchange or held of
record by at least 2,000 record shareholders or members; or

         c. A combination of cash and shares or membership interests as set
forth in subdivisions 2 a and 2 b of this subsection; or

         3. The transaction to be voted on is an "affiliated transaction" and is
not approved by a majority of "disinterested directors" as such terms are
defined in ss.13.1-725.

         D. The right of a dissenting shareholder to obtain payment of the fair
value of his shares shall terminate upon the occurrence of any one of the
following events:

         1. The proposed corporate action is abandoned or rescinded;

                                      C-2

         2. A court having jurisdiction permanently enjoins or sets aside the
corporate action; or

         3. His demand for payment is withdrawn with the written consent of the
corporation.

         E. Notwithstanding any other provision of this article, no shareholder
of a corporation located in a county having a county manager form of government
and which is exempt from income taxation under ss. 501 (c) or ss. 528 of the
Internal Revenue Code and no part of whose income inures or may inure to the
benefit of any private share holder or individual shall be entitled to dissent
and obtain payment for his shares under this article.

         ss.13.1-731. Dissent by nominees and beneficial owners.

         A. A record shareholder may assert dissenters' rights as to fewer than
all the shares registered in his name only if he dissents with respect to all
shares beneficially owned by any one person and notifies the corporation in
writing of the name and address of each person on whose behalf he asserts
dissenters' rights. The rights of a partial dissenter under this subsection are
determined as if the shares as to which he dissents and his other shares were
registered in the names of different shareholders.

         B. A beneficial shareholder may assert dissenters' rights as to shares
held on his behalf only if:

         1. He submits to the corporation the record shareholder's written
consent to the dissent not later than the time the beneficial shareholder
asserts dissenters' rights; and

         2. He does so with respect to all shares of which he is the beneficial
shareholder or over which he has power to direct the vote.

         ss.13.1-732. Notice of dissenters' rights.

         A. If proposed corporate action creating dissenters' rights under ss.
13.1-730 is submitted to a vote at a shareholders' meeting, the meeting notice
shall state that shareholders are or may be entitled to assert dissenters'
rights under this article and be accompanied by a copy of this article.

         B. If corporate action creating dissenters' rights under ss. 13.1-730
is taken without a vote of shareholders, the corporation, during the ten-day
period after the effectuation of such corporate action, shall notify in writing
all record shareholders entitled to assert dissenters' rights that the action
was taken and send them the dissenters' notice described in ss. 13.1-734.

         ss.13.1-733. Notice of intent to demand payment.

         A. If proposed corporate action creating dissenters' rights under ss.
13.1-730 is submitted to a vote at a shareholders' meeting, a shareholder who
wishes to assert dissenters' rights (i) shall deliver to the corporation before
the vote is taken written notice of his intent to demand payment for his shares
if the proposed action is effectuated and (ii) shall not vote such shares in
favor of the proposed action.

         B. A shareholder who does not satisfy the requirements of subsection A
of this section is not entitled to payment for his shares under this article.

         ss. 13.1-734. Dissenters' notice.


                                      C-3

         A. If proposed corporate action creating dissenters' rights under ss.
13.1-730 is authorized at a shareholders' meeting, the corporation, during the
ten-day period after the effectuation of such corporate action, shall deliver a
dissenters' notice in writing to all shareholders who satisfied the requirements
of ss. 13.1-733.

         B. The dissenters' notice shall:

         1. State where the payment demand shall be sent and where and when
certificates for certificated shares shall be deposited;

         2. Inform holders of uncertificated shares to what extent transfer of
the shares will be restricted after the payment demand is received;

         3. Supply a form for demanding payment that includes the date of the
first announcement to news media or to shareholders of the terms of the proposed
corporate action and requires that the person asserting dissenters' rights
certify whether or not he acquired beneficial ownership of the shares before or
after that date;

         4. Set a date by which the corporation must receive the payment demand,
which date may not be fewer than thirty nor more than sixty days after the date
of delivery of the dissenters' notice; and

         5. Be accompanied by a copy of this article.

         ss.13.1-735. Duty to demand payment.

         A. A shareholder sent a dissenters' notice described in ss. 13.1-734
shall demand payment, certify that he acquired beneficial ownership of the
shares before or after the date required to be set forth in the dissenters'
notice pursuant to subdivision 3 of subsection B of ss. 13.1-734, and, in the
case of certificated shares, deposit his certificates in accordance with the
terms of the notice.

         B. The shareholder who deposits his shares pursuant to subsection A of
this section retains all other rights of a shareholder except to the extent that
these rights are canceled or modified by the taking of the proposed corporate
action.

         C. A shareholder who does not demand payment and deposits his share
certificates where required, each by the date set in the dissenters' notice, is
not entitled to payment for his shares under this article.

         ss. 13.1-736. Share restrictions.

         A. The corporation may restrict the transfer of uncertificated shares
from the date the demand for their payment is received.

         B. The person for whom dissenters' rights are asserted as to

extent that these rights are canceled or modified by the taking of the proposed
corporate action.

         ss. 13.1-737. Payment.

         A Except as provided in ss. 13.1-738, within thirty days after receipt
of a payment demand made pursuant to ss. 13.1-735, the corporation shall pay the
dissenter the amount the corporation estimates to be the fair value of his
shares, plus accrued interest. The obligation of the corporation under this

                                      C-4


paragraph may be enforced (i) by the circuit court in the city or county where
the corporation's principal office is located, or, if none in this Commonwealth,
where its registered office is located or (ii) at the election of any dissenter
residing or having its principal office in the Commonwealth, by the circuit
court in the city or county where the dissenter resides or has its principal
office. The court shall dispose of the complaint on an expedited basis.

         B. The payment shall be accompanied by:

         1. The corporation's balance sheet as of the end of a fiscal year
ending not more than sixteen months before the effective date of the corporate
action creating dissenters' rights, an income statement for that year, a
statement of changes in shareholders' equity for that year, and the latest
available interim financial statements, if any;

         2. An explanation of how the corporation estimated the fair value of
the shares and of how the interest was calculated;

         3. A statement of the dissenters' right to demand payment underss.13.1-
739; and

         4. A copy of this article.

         ss.13.1-738. After-acquired shares.

         A. A corporation may elect to withhold payment required by ss. 13.1-737
from a dissenter unless he was the beneficial owner of the shares on the date of
the first publication by news media or the first announcement to shareholders
generally, whichever is earlier, of the terms of the proposed corporate action,
as set forth in the dissenters' notice.

         B. To the extent the corporation elects to withhold payment under
subsection A of this section, after taking the proposed corporate action, it
shall estimate the fair value of the shares, plus accrued interest, and shall
offer to pay this amount to each dissenter who agrees to accept it in full
satisfaction of his demand. The corporation shall send with its offer an
explanation of how it estimated the fair value of the shares and of how the
interest was calculated, and a statement of the dissenter's right to demand
payment under ss. 13.1-739.

         ss.13.1-739. Procedure if shareholder dissatisfied with payment or
offer.

         A. A dissenter may notify the corporation in writing of his own
estimate of the fair value of his shares and amount of interest due, and demand
payment of his estimate (less any payment under ss. 13.1-737), or reject the
corporation's offer under ss. 13.1-738 and demand payment of the fair value of
his shares and interest due, if the dissenter believes that the amount paid
under ss. 13.1-737 or offered under ss. 13.1-738 is less than the fair value of
his shares or that the interest due is incorrectly calculated.

         B. A dissenter waives his right to demand payment under this section
unless he notifies the corporation of his demand in writing under subsection A
of this section within thirty days after the corporation made or offered payment
for his shares.

         ss. 13.1-740. Court action.

         A. If a demand for payment under ss. 13.1-739 remains unsettled, the
corporation shall commence a proceeding within sixty days after receiving the
payment demand and petition the circuit court in the city or county described

                                      C-5


in subsection B of this section to determine the fair value of the shares and
accrued interest. If the corporation does not commence the proceeding within the
sixty-day period, it shall pay each dissenter whose demand remains unsettled the
amount demanded.

         B. The corporation shall commence the proceeding in the city or county
where its principal office is located, or, if none in this Commonwealth, where
its registered office is located. If the corporation is a foreign corporation
without a registered office in this Commonwealth, it shall commence the
proceeding in the city or county in this Commonwealth where the registered
office of the domestic corporation merged with or whose shares were acquired by
the foreign corporation was located.

         C. The corporation shall make all dissenters, whether or not residents
of this Commonwealth, whose demands remain unsettled parties to the proceeding
as in an action against their shares and all parties shall be served with a copy
of the petition. Nonresidents may be served by registered or certified mail or
by publication as provided by law.

         D. The corporation may join as a party to the proceeding any
shareholder who claims to be a dissenter but who has not, in the opinion of the
corporation, complied with the provisions of this article. If the court
determines that such shareholder has not complied with the provisions of this
article, he shall be dismissed as a party.

         E. The jurisdiction of the court in which the proceeding is commenced
under subsection B of this section is plenary and exclusive. The court may
appoint one or more persons as appraisers to receive evidence and recommend a
decision on the question of fair value. The appraisers have the powers described
in the order appointing them, or in any amendment to it. The dissenters are
entitled to the same discovery rights as parties in other civil proceedings.

         F. Each dissenter made a party to the proceeding is entitled to
judgment (i) for the amount, if any, by which the court finds the fair value of
his shares, plus interest, exceeds the amount paid by the corporation or (ii)
for the fair value, plus accrued interest, of his after-acquired shares for
which the corporation elected to withhold payment under ss. 13.1-738.

         ss.13.1-741. Court costs and counsel fees.

         A. The court in an appraisal proceeding commenced under ss. 13.1-740
shall determine all costs of the proceeding, including the reasonable
compensation and expenses of appraisers appointed by the court. The court shall
assess the costs against the corporation, except that the court may assess costs
against all or some of the dissenters, in amounts the court finds equitable, to
the extent the court finds the dissenters did not act in good faith in demanding
payment under ss. 13.1-739.

         B. The court may also assess the reasonable fees and expenses of
experts, excluding those of counsel, for the respective parties, in amounts the
court finds equitable:

         1. Against the corporation and in favor of any or all dissenters if the
court finds the corporation did not substantially comply with the requirements
ofss.ss.13.1-732 through 13.1-739; or

         2. Against either the corporation or a dissenter, in favor of any other
party, if the court finds that the party against whom the fees and expenses are
assessed did not act in good faith with respect to the rights provided by this
article.

                                      C-6


         C. If the court finds that the services of counsel for any dissenter
were of substantial benefit to other dissenters similarly situated, the court
may award to these counsel reasonable fees to be paid out of the amounts awarded
the dissenters who were benefited.

         D. In a proceeding commenced under subsection A of ss. 13.1-737 the
court shall assess the costs against the corporation, except that the court may
assess costs against all or some of the dissenters who are parties to the
proceeding, in amounts the court finds equitable, to the extent the court finds
that such parties did not act in good faith in instituting the proceeding.
