                                 AVERSTAR, INC.
                                23 FOURTH AVENUE
                              BURLINGTON, MA 01803

                                MERGER PROPOSAL

Dear stockholders:

    We are pleased to report that the Boards of Directors of AverStar and The
Titan Corporation have approved a merger agreement which provides for the merger
of a Titan subsidiary into AverStar. As a result of the proposed merger, we will
become a wholly owned subsidiary of Titan. Our board of directors believes that
the combination with Titan enables our stockholders to realize a significant
return on their investment, while allowing our business to continue to grow.

    If we complete the proposed merger:

    - our seven classes of common stock, Class A, Class B, Class C, Class D,
      Class E, Class F and Class G, will be converted into one class of common
      stock as provided in our certificate of incorporation; and

    - you will become a stockholder of Titan and receive the number of shares of
      Titan common stock determined according to a formula contained in the
      merger agreement in exchange for your shares of our common stock.


    These transactions are more fully described in the accompanying proxy
statement. If the merger were completed on May 19, 2000, AverStar stockholders
would own approximately 7.07% of Titan's outstanding common stock immediately
after the proposed merger. Titan's common stock is listed on the New York Stock
Exchange under the trading symbol "TTN."


    This proxy statement also serves as Titan's prospectus under the Securities
Act of 1933 for the issuance of Titan's common stock to you in the proposed
merger. We encourage you to read this joint proxy statement/prospectus
carefully. IN PARTICULAR, YOU SHOULD REVIEW THE MATTERS REFERRED TO UNDER "RISK
FACTORS" STARTING ON PAGE 14.

    We are asking our stockholders to approve the proposed merger, the merger
agreement and the related transactions at a special meeting. We cannot complete
the proposed merger unless a majority of the shares of our voting common stock
vote to approve it.

    The date, time and place of our special meeting is:


    10:30 a.m., Eastern Time
    June 26, 2000
    AverStar, Inc.
    23 Fourth Avenue
    Burlington, MA 01803


    We appreciate your consideration in this matter.


                                          Sincerely,
                                          /s/ MICHAEL B. ALEXANDER
                                          Michael B. Alexander

                                          CHIEF EXECUTIVE OFFICER


                            YOUR VOTE IS IMPORTANT.
               PLEASE COMPLETE, SIGN, DATE AND RETURN YOUR PROXY.


             This proxy statement/prospectus is dated May 24, 2000
              and is first being mailed on or about May 26, 2000.

                     QUESTIONS AND ANSWERS ABOUT THE MERGER

Q.  WHY ARE AVERSTAR AND TITAN PROPOSING THE MERGER?

A.  The boards of directors of AverStar and Titan believe the combined strengths
    of the two companies will enable them to compete more effectively than
    either can compete alone. The merger will allow both Titan and AverStar to
    take advantage of the trend toward consolidation in the government
    information technology industry in recent years. The combined company's
    greater resources will enhance its ability to effectively compete for large,
    multiple award contracts, will provide it access to broader information
    technology and commercial customer bases and broader technology and
    expertise. To review the background and reasons for the merger in greater
    detail, see page 27.

Q.  WHAT WILL HAPPEN TO AVERSTAR AS A RESULT OF THE MERGER?

A.  If the merger is completed, AverStar will become a wholly owned subsidiary
    of Titan.

Q.  WHAT WILL I RECEIVE IN THE MERGER?

A.  After the consolidation of all classes of AverStar common stock into one
    class of AverStar common stock as required by AverStar's certificate of
    incorporation and stockholders' agreement, all shares of AverStar common
    stock will be converted into the right to receive shares of Titan common
    stock in an amount which will be determined at the time of the merger based
    on the average of the closing sale prices of the Titan common stock on the
    New York Stock Exchange for the ten consecutive trading days ending two
    trading days immediately before the merger closing date.

Q.  HOW WILL THE MERGER AFFECT MY FUTURE DIVIDENDS?

A.  Neither Titan nor AverStar has historically paid dividends to its common
    stockholders. Titan does not anticipate that it will pay dividends to its
    common stockholders in the foreseeable future.

Q.  WHAT ARE THE TAX CONSEQUENCES OF THE MERGER TO AVERSTAR STOCKHOLDERS?

A.  In general, AverStar stockholders who exchange their shares of AverStar
    common stock for shares of Titan common stock as a result of the merger will
    not recognize any gain or loss on the exchange for U.S. federal income tax
    purposes. To review the tax consequences to AverStar stockholders in greater
    detail, see page 35.

Q.  WHEN DO AVERSTAR AND TITAN EXPECT THE MERGER TO BE COMPLETED?

A.  AverStar and Titan are working to complete the merger as quickly as
    possible. We hope to complete the merger during the second quarter of 2000.

Q.  ARE AVERSTAR STOCKHOLDERS ENTITLED TO DISSENTERS' RIGHTS?

A.  Yes. Under Delaware law, which governs AverStar and the rights of its
    stockholders, AverStar stockholders who comply with section 262 of the
    Delaware General Corporation Law are entitled to dissenters' rights of
    appraisal for their shares in cash instead of Titan shares by reason of the
    merger.

<PAGE>
Q.  WHO MUST APPROVE THE MERGER?


A.  In addition to the boards of directors of AverStar and Titan, which have
    already approved the merger, the stockholders of AverStar must adopt the
    merger agreement. The AverStar special meeting of stockholders to approve
    the merger will take place on June 26, 2000. AverStar and Titan must also
    obtain some regulatory approvals for the merger.


Q.  WHAT DO I NEED TO DO NOW?

A.  You should carefully read and consider the information contained in this
    proxy statement/ prospectus. You should then complete and sign your proxy
    and return it in the enclosed return envelope as soon as possible so that
    your shares of AverStar common stock will be represented at the AverStar
    special meeting. If you sign, date and mail your proxy card without
    identifying how you want to vote, your proxy will be voted "FOR" adoption of
    the merger agreement and approval of the merger and related transactions. If
    you do not vote in person or by returning your completed proxy card, your
    failure to vote will have the same effect as a vote "AGAINST" the merger
    agreement.

Q.  CAN I CHANGE MY VOTE AFTER I MAIL MY SIGNED PROXY?

A.  Yes. You can change your vote at any time before your proxy is voted at the
    special meeting of AverStar stockholders. You can do this in one of three
    ways. First, you can send a written notice stating that you would like to
    revoke your proxy. Second, you can complete and submit a new proxy
    reflecting a later date. If you choose either of these two methods, you must
    submit your notice of revocation or your new proxy to the address on page 25
    before the vote at the special meeting. Third, you can attend the special
    meeting and vote in person.

Q.  SHOULD I SEND IN MY STOCK CERTIFICATES NOW?

A.  NO, YOU SHOULD NOT SEND IN YOUR STOCK CERTIFICATES WITH YOUR PROXY. Titan
    will send you written instructions on how to exchange your stock
    certificates.

Q.  WHO CAN HELP ANSWER MY QUESTIONS?

A.  If you have any questions about the merger or if you need additional copies
    of this proxy statement/prospectus or the enclosed proxy, you should contact
    AverStar at the following address:

THE COMPANIES (PAGE 71)


    The parties to the merger agreement are The Titan Corporation,
AverStar, Inc. and V T Acquisition Corp.

THE TITAN CORPORATION

Telephone: (619) 552-9500

    The Titan Corporation is a leading provider of communications and
information solutions to U.S. military and allied government agencies, as well
as commercial customers. Titan's systems, products and services enable
government and commercial customers to generate, process, transmit, store and
distribute information in a secure, cost-effective and timely manner. Titan has
organized its business into five segments: information technologies, or IT,
software systems, medical sterilization and food pasteurization, communications
systems, and emerging businesses.

AVERSTAR, INC.

23 Fourth Avenue
Burlington, Massachusetts 01803
Telephone: (781) 221-6990

    AverStar provides information technology, or IT, services and software
products for the mission-critical systems of a significant number of civilian
and defense agencies of the United States government. AverStar also provides IT
services and software products to large commercial companies. During its 30-year
history, AverStar has maintained a strong record of customer satisfaction based
on the quality and reliability of its services and products.

V T ACQUISITION CORP.

3033 Science Park Road
San Diego, California 92121
Telephone: (619) 552-9500

    V T Acquisition Corp. is a wholly owned subsidiary of Titan which Titan
formed solely for the purpose of completing the merger. V T Acquisition Corp. is
a newly formed corporation that to date has not conducted any activities other
than activities related to its formation, the execution of the merger agreement
and the preparation of this proxy statement/prospectus.

THE MERGER (PAGE 27)

    The merger agreement is attached as Appendix A to this proxy
statement/prospectus and is incorporated by reference into this document. We
encourage you to read the entire merger agreement because it is the legal
document that governs the merger.

                                       3
<PAGE>

    In the merger, Titan will acquire AverStar by merging V T Acquisition Corp.
with and into AverStar. AverStar will become a wholly owned subsidiary of Titan
and AverStar stockholders will become stockholders of Titan. Based on the number
of shares of Titan and AverStar common stock outstanding on May 19, 2000, if the
merger were completed on that date, AverStar stockholders would own
approximately 7.07% of Titan's outstanding common stock immediately after the
merger.


    Some AverStar stockholders, who are members of AverStar's management and
board of directors and who collectively own approximately 31.3% of AverStar's
outstanding voting common stock, have signed an agreement to vote their shares
in favor of adoption of the merger agreement and approval of the merger and
related transactions. Each of these stockholders also has given Titan an
irrevocable proxy authorizing Titan to vote the stockholder's shares of AverStar
voting common stock in favor of adoption of the merger agreement and approval of
the merger and related transactions. These stockholders are referred to as the
AverStar Principal Stockholders in this proxy statement/prospectus. See "Terms
of the Merger Agreement and Related Transactions--AverStar Voting Agreement"
beginning on page 57 for more information about the voting agreement.

WHAT YOU WILL RECEIVE IN THE MERGER (PAGE 39)

    In connection with the merger, AverStar's seven classes of common stock,
Class A, Class B, Class C, Class D, Class E, Class F and Class G, will be
converted into one class of common stock as required by AverStar's certificate
of incorporation and stockholders agreement.

    In the merger, after the conversion of all classes of AverStar common stock
into one class of common stock as required by AverStar's certificate of
incorporation and stockholders' agreement, each outstanding share of AverStar
common stock will be converted into the right to receive shares of Titan common
stock. The number of Titan common shares you will be entitled to receive for
each share of AverStar common stock that you own will depend on the exchange
ratio of Titan common stock to AverStar common stock. The exchange ratio has not
been fixed in the merger agreement, but will be calculated at the time of the
merger according to a formula contained in the merger agreement. Under this
formula, the exchange ratio will be based on the average of the closing sale
prices of Titan common stock on the New York Stock Exchange for the ten
consecutive trading days ending two trading days immediately before the merger
closing date.

    - If the average Titan stock price is less than $39.60, (a) AverStar has the
      right to terminate the merger agreement, unless Titan elects to have the
      exchange ratio fixed at an amount equal to the quotient obtained by
      dividing the product of the "AverStar stock value" (as defined below)
      multiplied by 0.90 by the average Titan stock price or (b) if AverStar
      does not exercise this termination right and Titan does not make the
      election described in (a), the exchange ratio will be equal to the
      quotient obtained by dividing the AverStar stock value by $44.00.

    - If the average Titan stock price is greater than or equal to $39.60 and
      less than $44.00, the exchange ratio will be equal to the quotient
      obtained by dividing the AverStar stock value by $44.00.

    - If the average Titan stock price is greater than or equal to $44.00 and
      less than or equal to $56.00, the exchange ratio will be equal to the
      quotient obtained by dividing the AverStar stock value by the average
      Titan stock price.

    - If the average Titan stock price is greater than $56.00 and less than or
      equal to $61.60, the exchange ratio will be equal to the quotient obtained
      by dividing the AverStar stock value by $56.00.

    - If the average Titan stock price is greater than $61.60, (a) Titan has the
      right to terminate the merger agreement unless AverStar elects to have the
      exchange ratio fixed at an amount equal to the quotient obtained by
      dividing the product of the AverStar stock value multiplied by 1.10 by

                                       4
<PAGE>
      the average Titan stock price or (b) if Titan does not exercise this
      termination right and AverStar does not make the election described in
      (a), the exchange ratio will be equal to the quotient obtained by dividing
      the AverStar stock value by $56.00.

    As used in this proxy statement/prospectus, the term "AverStar stock value"
means the result of dividing the "transaction value" by the sum of (a) the
number of shares of AverStar common stock outstanding as of the merger effective
time (assuming for such purposes, that as of the merger effective time, all
shares of AverStar capital stock were converted into a single class of common
stock as required in AverStar's certificate of incorporation) and (b) the number
of shares of AverStar common stock which would be issuable with respect to all
vested AverStar options outstanding as of the merger effective time if all of
the conditions to exercisability of such option had been satisfied at that time
and (c) one-half of the number of shares of AverStar common stock which would be
issuable with respect to all unvested AverStar options outstanding as of the
merger effective time if all of the conditions to exercisability of such options
(including, without limitation, vesting) had been satisfied at that time.

    As used in this proxy statement/prospectus, the term "transaction value"
means $205 million plus (i) the sum of (a) the total consideration payable to
AverStar upon the exercise of all vested AverStar options issued and outstanding
immediately prior to the merger effective time and (b) one-half of the total
consideration payable to AverStar upon the exercise of all unvested AverStar
options issued and outstanding immediately prior to the merger effective time,
less (ii) AverStar's estimated net debt as of the merger closing date (as
certified by AverStar's chief financial officer two days prior to the merger
closing date), less (iii) all payments made to AverStar common stockholders
after the date of the merger agreement and prior to the merger effective time to
redeem AverStar common stock.

    FOR INFORMATION ON SOME OF THE POSSIBLE MARKET VALUES OF TITAN SHARES YOU
COULD RECEIVE, SEE "TERMS OF THE MERGER AGREEMENT AND RELATED
TRANSACTIONS--GENERAL--CONVERSION OF AVERSTAR COMMON STOCK" AND "--CONVERSION OF
AVERSTAR COMMON STOCK TO TITAN COMMON STOCK" BEGINNING ON PAGE 39.

    Titan will not issue fractional shares of its common stock in the merger.
Instead, fractional shares will be rounded up to the nearest whole share of
Titan common stock.

ESCROW (PAGE 44)

    Under the merger agreement, Titan will withhold shares of its common stock
issuable to AverStar stockholders in connection with the merger in an amount
equal to 5% of the transaction value divided by the average of the closing sale
prices of Titan common stock on the New York Stock Exchange for the ten
consecutive trading days ending two trading days immediately before the merger
closing date. Promptly after the merger, Titan will deposit such shares in
escrow with First Union National Bank, as escrow agent, as security for
performance of AverStar's indemnity obligations to Titan in the merger agreement
and to pay Titan any required closing adjustment due under the merger agreement.
The amount of closing adjustment will be equal to the amount by which the net
debt of AverStar and its subsidiaries as of the closing date of the merger is
greater or less than the estimated net debt as set forth in the certificate that
AverStar is required to deliver to Titan two days prior to the closing date of
the merger. Any amounts of losses to which Titan or its affiliates are entitled
to indemnification will be determined by a loss adjustment and paid for out of
the shares of Titan common stock held in escrow. The escrow will be governed by
a separate escrow agreement, a form of which is attached as Appendix B.

    On the earlier of (a) five business days after the final determination of
the closing adjustment and loss adjustment (including, without limitation, final
resolution of any disputes thereto); or (b) 90 days after the closing of the
merger, the shares of Titan common stock held in escrow, other than any amounts
taken out to pay any closing or loss adjustment or any amounts that are pending
final resolution of any disputes therefrom, will be released to the former
holders of AverStar common stock

                                       5
<PAGE>
(other than those who exercised appraisal rights) pro-rata in accordance with
the number of shares of Titan common stock held by each former AverStar
stockholder immediately after the effective time of the merger.

TREATMENT OF OPTIONS IN THE MERGER (PAGE 44)

    Titan will assume each outstanding option to purchase shares of AverStar
common stock at the effective time of the merger. Each assumed option will be
converted into an option to purchase shares of Titan common stock. The number of
shares subject to the assumed options and the option exercise prices will be
adjusted based on the exchange ratio. All other terms of the options will remain
unchanged.

EXCHANGE OF STOCK CERTIFICATES (PAGE 37)

    You will receive a letter of transmittal that will provide you with
instructions on how to exchange your AverStar stock certificates for stock
certificates representing the Titan common stock you receive in the merger.

PLEASE DO NOT SEND YOUR STOCK CERTIFICATES AT THIS TIME.

SPECIAL MEETING OF AVERSTAR STOCKHOLDERS (PAGE 24)

    Under Delaware law, AverStar stockholders must vote to adopt the merger
agreement in order for AverStar to complete the merger.


    The special meeting of AverStar stockholders will be held at the offices of
AverStar at 23 Fourth Avenue, Burlington, Massachusetts 01803 on June 26, 2000,
at 10:30 a.m., eastern time. At the special meeting, you will be asked to vote
to adopt the merger agreement and to approve the merger and the other
transactions contemplated by the merger agreement.



    You may vote, or submit a proxy to vote, at the special meeting if you were
a record holder of AverStar voting common stock at the close of business on
May 19, 2000, which is the record date for the special meeting. If you return
your proxy, you may revoke it at any time before the vote at the special meeting
by sending a later-dated proxy or a written notice revoking the proxy to the
secretary of AverStar or by attending the meeting and voting in person.


VOTE REQUIRED (PAGE 24)


    A majority of the shares of AverStar voting common stock issued and
outstanding on May 19, 2000 must vote to approve the merger and adopt the merger
agreement. If you do not vote your shares of AverStar voting common stock, the
effect will be the same as a vote against the merger.



    As of May 19, 2000, directors and officers of AverStar beneficially owned
25.3% of the outstanding shares of AverStar common stock and 28.5% of the
outstanding shares of AverStar voting common stock.


AVERSTAR'S REASONS FOR THE MERGER (PAGE 29)

    In reaching its decision to approve the merger and recommend the approval of
the merger agreement to the AverStar stockholders, the AverStar board of
directors considered and analyzed a number of factors, including the following:

    - the opportunity for AverStar stockholders to own stock of a publicly
      traded company, with greater resources and a more diversified business;

                                       6
<PAGE>
    - the realization of full value for AverStar's stockholders and a
      significant return to them on their investment, based on the current value
      of the Titan common stock to be issued in the merger;

    - the access to Titan's complimentary base of customers and to broader
      technology and expertise to offer to existing and potential customers;

    - the benefits of consolidation in response to the current market trends in
      the federal IT industry toward larger, multiple-award contracts; and

    - the potential opportunities in a larger company for AverStar employees and
      customers.

RECOMMENDATION OF AVERSTAR'S BOARD OF DIRECTORS (PAGE 29)

    The AverStar board of directors has concluded unanimously that the merger is
in the best interests of, and that the terms of the merger are fair to, AverStar
and to the AverStar stockholders. The AverStar board of directors has
recommended unanimously that you vote "FOR" adoption of the merger agreement and
approval of the merger and the other transactions contemplated by the merger
agreement.

INTERESTS OF AVERSTAR'S DIRECTORS AND OFFICERS IN THE MERGER (PAGE 31)

    In considering the recommendation of the AverStar board of directors that
you vote to adopt the merger agreement, you should be aware that some of the
AverStar directors and executive officers identified in this proxy
statement/prospectus have interests in the merger that are different from, or in
addition to, their rights as AverStar stockholders.

CLEARANCE UNDER FEDERAL ANTITRUST LAWS (PAGE 35)

    In order to complete the merger, AverStar and Titan had to make filings with
the Department of Justice and the Federal Trade Commission in compliance with
federal antitrust law. Before the merger can occur, the applicable pre-merger
30-day waiting period under this law must expire or be terminated.

CONDITIONS TO THE MERGER (PAGE 53)

    The merger will not be completed unless customary conditions are satisfied
or waived by Titan or AverStar. Some conditions may not be waived, however, such
as approval of the merger by the AverStar stockholders, clearance under federal
antitrust laws and the absence of governmental action to block the merger.

TERMINATION OF THE MERGER AGREEMENT (PAGE 55)

    The merger agreement may be terminated by either Titan or AverStar in a
number of circumstances, in which case the merger will not be completed.
Breaches of the merger agreement, withdrawal by the AverStar board of directors
of its recommendation that AverStar stockholders adopt the merger agreement and
the failure of the AverStar stockholders to adopt the merger agreement are some
of the factors that could permit Titan or AverStar to terminate the merger
agreement. See "Terms of the Merger Agreement and Related
Transactions--Termination of the Merger Agreement; Termination Fee" beginning on
page 55 for a more detailed description of the termination provisions of the
merger agreement.

TERMINATION FEE (PAGE 55)

    If the merger agreement is terminated, under some circumstances AverStar may
have to pay Titan a termination fee of up to $4 million. See "Terms of the
Merger Agreement and Related

                                       7
<PAGE>
Transactions--Termination of the Merger Agreement; Termination Fee" beginning on
page 55 for more information about when this termination fee or other
termination payments may be payable.

FEDERAL INCOME TAX CONSEQUENCES (PAGE 35)

    It is a condition to the merger that Titan and AverStar receive opinions
from their counsel to the effect that the merger will constitute a
reorganization for U.S. federal income tax purposes. Accordingly, AverStar
stockholders will not recognize gain or loss upon the exchange of their AverStar
common stock for Titan common stock in the merger. To review the expected
federal income tax consequences of the merger, see the tax discussion beginning
on page 35.

    The tax consequences of the merger to AverStar stockholders will depend on
the particular facts of each AverStar stockholder's own situation. Therefore,
AverStar stockholders should consult their own tax advisors regarding the
merger's specific tax consequences.

ACCOUNTING TREATMENT (PAGE 32)

    Titan and AverStar have structured the merger to be accounted for as a
pooling of interests in accordance with generally accepted accounting
principles. This means that the two companies will be treated as if they had
always been combined for accounting and financial reporting purposes.

DISSENTERS' RIGHTS (PAGE 33)

    Under Delaware law, which governs your rights as an AverStar stockholder,
you will be entitled to dissent from the merger and to exercise appraisal rights
in connection with the merger.


DIFFERENCES IN THE RIGHTS OF STOCKHOLDERS (PAGE 99)



    If you own AverStar common stock, you will receive Titan common stock and
become a stockholder of Titan after the merger. Your rights will continue to be
governed by Delaware law, but also will be governed by Titan's certificate of
incorporation, bylaws and shareholder rights plan, rather than by AverStar's
certificate of incorporation, bylaws and stockholders agreement. For a
description of how your rights as a Titan stockholder would differ from your
rights as an AverStar stockholder, see "Comparative Rights of Titan Stockholders
and AverStar Stockholders" beginning on page 99.



WHERE YOU CAN FIND MORE INFORMATION (PAGE 108)



    If you would like more information about Titan, you can find this
information in documents filed by Titan with the Securities and Exchange
Commission. These documents are identified on page 108. Instructions on how you

(1) For purposes of computing the ratio of earnings to fixed charges, earnings
    consist of income before income taxes plus fixed charges and "fixed charges"
    consist of interest expense (including amortization of debt discount and
    expense), leasing expense and the estimated interest factor attributable to
    rentals. The ratio of earnings to combined fixed charges and preferred
    dividends was 1.5x during 1995, 2.1x during 1996, 1.4x during 1997, 2.4x

                 SELECTED HISTORICAL FINANCIAL DATA OF AVERSTAR


    The following tables set forth AverStar's selected historical financial
data. These tables do not present all of AverStar's financial information. You
should read this information together with AverStar's financial statements and
the notes to those statements contained in this proxy statement/ prospectus and
the information under "Information About AverStar--Management's Discussion and
Analysis of Financial Condition and Results of Operations." On March 13, 1995,
an investor group formed a holding company which acquired Intermetrics
(AverStar's predecessor) in August 1995. Substantially all data for the period
March 13, 1995 through February 29, 1996 relate to the operations and financial
position of Intermetrics. The selected financial data for the 12 months ended
February 29, 1996, which are unaudited, combine the two preceding columns which
reflect the operations of Intermetrics for the first six months of the period
based on Intermetrics' basis of accounting prior to the acquisition, and
AverStar's operations giving effect to the acquisition of Intermetrics in
August 1995. In February 1998, AverStar acquired Pacer, whose results of
operations are included from the date of acquisition in AverStar's results for
the 12 months ended December 31, 1998. In March 1999, AverStar acquired Computer
Based Systems, Inc. whose results of operations are included from the date of
acquisition in AverStar's results for the 12 months ended December 31, 1999. The
selected financial data for the 12 months ended February 28, 1997, the
10 months ended December 31, 1997 and the 12 months ended December 31, 1998, and
the 12 months ended December 31, 1999, are derived from AverStar's audited
financial statements. The results of operations for the three months ended March
31, 1999 and 2000 and as of March  31, 2000 are derived from unaudited financial
statements.

                      COMPARATIVE UNAUDITED PER SHARE DATA


    The following table shows selected historical per share data of Titan and
AverStar and combined per share data on an unaudited pro forma combined basis
for the years ended December 31, 1999, 1998 and 1997 after giving effect to the
merger as if it had occurred on January 1, 1997 under the pooling of interests
method of accounting. The Titan pro forma combined per share data for the year
ended December 31, 1999 combines the historical per share data of Titan (which
includes the pooling of interests with ACS) with the historical per share data
of Mainsaver, Assist and SFG as if each company had been combined with Titan on
January 1, 1999. The pro forma combined per share data assume that .5150 of a
share of Titan common stock had been issued in exchange for each outstanding
share of AverStar common stock. You should read this information in conjuction
with the selected historical audited and unaudited financial information
included elsewhere in this proxy statement/ prospectus and the historical
audited and unaudited financial statements of Titan and AverStar and related
notes that are included elsewhere or incorporated by reference in this proxy
statement/ prospectus.


    The per share data presented below are derived from the historical
consolidated financial statements of Titan and AverStar, of which the Titan
financial statements are incorporated in this proxy statement/prospectus by
reference and the AverStar financial statements are included herein. The
unaudited pro forma combined results of Titan and of AverStar are not
necessarily indicative of results of operations that would have resulted if the
merger had been completed at the beginning of the periods indicated or of the
results that will be achieved in the future.

</TABLE>


- ------------------------

(1) The historical book value per share is computed by dividing stockholders'
    equity by the number of shares of common stock and equivalents outstanding
    at the end of each period. The pro forma book value per share is computed by
    dividing pro forma stockholders' equity by the pro forma number of shares of
    common stock and equivalents at the end of each period.

(2) Titan estimates that Titan and AverStar will incur approximately
    $11.6 million of primarily direct transaction and employee termination costs
    associated with the merger, which will be charged to operations as the costs
    are incurred. The book value per share data under pro forma combined per
    Titan share give effect to estimated costs of $8.1 million, net of tax, as
    if such costs had been incurred and charged to operations as of
    December 31, 1999. These costs and this charge are not included in the pro
    forma income per share data. See "Unaudited Pro Forma Financial Information"
    and the related notes in this proxy statement/prospectus.


(3) The amounts for equivalent pro forma combined per AverStar share are
    calculated by dividing the amounts for pro forma combined per Titan share by
    an assumed total exchange of 3,863,000 Titan shares for all outstanding
    shares and outstanding options of AverStar (or a .5150 exchange ratio based
    upon total diluted AverStar shares and options as of December 31, 1999 of
    7,500,000).

                                  RISK FACTORS

    YOU SHOULD CAREFULLY CONSIDER THE FOLLOWING RISK FACTORS RELATING TO THE
MERGER AND OWNERSHIP OF TITAN COMMON STOCK BEFORE YOU DECIDE WHETHER TO VOTE TO
ADOPT THE MERGER AGREEMENT AND APPROVE THE MERGER AND RELATED TRANSACTIONS. YOU
ALSO SHOULD CONSIDER THE OTHER INFORMATION IN THIS PROXY STATEMENT/PROSPECTUS
AND THE OTHER DOCUMENTS CONSIDERED A PART OF THIS PROXY STATEMENT/PROSPECTUS.
FOR INFORMATION ABOUT THESE OTHER DOCUMENTS, SEE "WHERE YOU CAN FIND MORE
INFORMATION."

RISKS RELATING TO THE MERGER

    TITAN CANNOT ASSURE YOU THAT TITAN'S AND AVERSTAR'S BUSINESS OPERATIONS WILL
BE SUCCESSFULLY INTEGRATED.

    If Titan and the stockholders of the combined company are to realize the
anticipated benefits of the merger, the operations of Titan and AverStar must be
integrated and combined efficiently. Titan cannot assure you that the
integration will be successful or that the anticipated benefits of the merger
will be fully realized. Similarly, Titan cannot guarantee that the AverStar
stockholders will achieve greater value through their ownership of Titan common
stock than they would have achieved as stockholders of AverStar as a separate
entity. The dedication of Titan's management resources to integration activities
may detract attention from the day-to-day business of the combined company. The
difficulties of integration may be increased by the need to coordinate
geographically separate organizations, integrate personnel with disparate
business backgrounds and combine different corporate cultures. This integration
may also be more difficult due to Titan's integration challenges as a result of
its recently completed acquisitions or any future acquisitions. Titan cannot
assure you that there will not be substantial costs associated with the
integration process, that integration activities will not result in a decrease
in revenues or a decrease in the value of Titan common stock, or that there will
not be other material adverse effects from Titan's integration efforts.

    THE EXPECTED COSTS OF THE MERGER WILL BE SUBSTANTIAL.

    Titan estimates that it will incur primarily direct transaction costs of
approximately $11.6 million associated with the merger. These costs will be
charged to operations as incurred. This amount is a preliminary estimate only;
there can be no assurance that Titan will not actually incur charges in excess
of this estimate.

    SALES OF SUBSTANTIAL AMOUNTS OF TITAN'S COMMON STOCK IN THE OPEN MARKET BY
AVERSTAR STOCKHOLDERS COULD DEPRESS TITAN'S STOCK PRICE.


    If AverStar stockholders sell substantial amounts of Titan common stock in
the public market following the merger, including shares issued upon the
exercise of outstanding options, the market price of Titan common stock could
fall. These sales might also make it more difficult for Titan to sell equity or
equity-related securities at a time and price that it otherwise would deem
appropriate. Based on the number of outstanding shares of AverStar common stock
as of May 19, 2000, Titan will issue approximately 3,862,281 shares of Titan
common stock in the merger. In addition, Titan will assume all outstanding
options to purchase AverStar common stock, which will be converted into options
to acquire shares of Titan common stock using the same exchange ratio which is
applicable to AverStar common stock in the merger. All of the shares of Titan
common stock issued to stockholders of AverStar, including those issued upon the
exercise of options, will be freely tradable without restrictions or further
registration under the Securities Act of 1933, unless you are an AverStar
"affiliate," as that term is defined under the Securities Act, at the time the
merger is submitted for approval by AverStar stockholders. The term "affiliate"
would generally include directors, executive officers and some significant
stockholders of AverStar.

RISKS RELATING TO TITAN'S BUSINESS AND COMMON STOCK


    THE CAYENTA, SUREBEAM AND TITAN WIRELESS BUSINESSES OPERATE IN EMERGING
MARKETS, AND TITAN WILL BE UNABLE TO EXPAND THESE BUSINESSES AS IT EXPECTS IF
THE PRINCIPAL PRODUCTS AND SERVICES OF THOSE BUSINESSES DO NOT MEET WITH MARKET
ACCEPTANCE.



    Titan is committed to creating, building and launching technology-based
businesses. As part of implementing that strategy, Titan has created, built and
launched technology-based businesses known as Cayenta, SureBeam and Titan
Wireless. If any of the primary markets targeted by Cayenta, SureBeam or Titan
Wireless fails to develop as Titan anticipates, Titan's revenues will be less
than expected, its business will suffer and it may be unable to recoup the
investments it has made to develop and market the principal products and
services of those businesses.



    To grow as currently contemplated, Titan will need to derive an increasing
portion of its revenues from the Cayenta, SureBeam and Titan Wireless
businesses.


    To date, none of Cayenta's revenues have been derived from direct sales by
it of its total services provider offering, or TSP. Cayenta's only TSP-related
revenues have resulted from providing TSP services to the customers of a joint
venture in which it holds a 10% equity interest. The market for TSP offerings
has only recently begun to develop, and Cayenta cannot be certain that the
market for TSP offerings will develop.


    The use of the SureBeam electron beam technology for food irradiation has
only recently been approved by the applicable regulatory authorities in the
United States. Accordingly, a market for pasteurized foods has only recently
begun to develop, and its continued development will depend on broad acceptance
of irradiated foods by customers, food producers and providers, restaurant
chains and food retailers. This acceptance may not occur.


    Titan Wireless' principal strategy is to provide products used in telephony
systems in developing countries. Titan cannot guarantee that a substantial
market for telephony services in developing countries will ever develop, or if
such a market does develop, that fixed-site satellite equipment will capture a
significant portion of that market. The development of a market for telephony
services in developing countries will depend upon a variety of factors including
whether a particular country has sufficient resources to support such a market
and whether the telephony services are offered at a reasonable cost to the end
users of such services. Titan Wireless' ability to penetrate the telephony
market in developing countries will be adversely affected to the extent that
other competing elements of the communications infrastructure, such as telephone
lines, other satellite-delivered solutions and fiber optic cable and television
cable, are installed in the developing countries. In addition, the development
and implementation of telephony systems will be dependent upon, among other
items, the continued development of necessary technologies, continued financial
and other support from governmental agencies, the implementation of
cost-effective systems, market acceptance for such systems and approval by
appropriate regulatory agencies.

    TITAN HAS A LIMITED HISTORY OF COMMERCIALIZING NEW TECHNOLOGIES AND ITS
COMMERCIAL BUSINESSES MAY NOT REMAIN OR EVER BECOME SUCCESSFUL.


    In 1991, Titan adopted a strategy of seeking to develop commercial
businesses using technology developed in its defense businesses. The SureBeam
and Titan Wireless businesses are a product of this strategy. Many of Titan's
commercial businesses are in an early stage of development or have only recently
begun to offer their products, services, systems or solutions in the emerging
markets in which they operate. These technology-based businesses are subject to
risks inherent in companies at these early stages of development, including:


    - the risks that their base technology will become obsolete and that they
      will fail to respond in a timely and cost-effective manner to rapid
      technological changes;

                                       15
<PAGE>
    - the risks associated with operating in markets that are subject to a high
      degree of competition;

    - the risk that they will have inadequate management resources to capitalize
      on market opportunities and execute their strategy;

    - the risk that they will be unable to manage rapid growth effectively;

    - the risk that they will be unable to execute successfully each portion of
      their business strategy on schedule;

    - the risk that Titan may not identify markets with sufficient opportunities
      to justify its investments in products and solutions for these markets;

    - the market and operating risks that are unique to each particular
      business; and

    - the risk that adequate capital may not be available to fund their
      continued development.

    TITAN CANNOT GUARANTEE THAT CAYENTA'S PENDING INITIAL PUBLIC OFFERING WILL
CLOSE OR THAT TITAN WILL BE ABLE TO EXECUTE ON ITS STRATEGY OF OBTAINING PUBLIC
OR PRIVATE FINANCING TO FUND THE GROWTH OF ITS COMMERCIAL BUSINESSES.

    As part of Titan's strategy of seeking external financing to grow its
commercial businesses, Titan's Cayenta subsidiary filed a registration statement
for an initial public offering of its common stock in December 1999, as last
amended in March 2000. Titan cannot guarantee that Cayenta will succeed in
completing the offering, which may be adversely affected by market conditions or
other factors. Titan has extended a credit facility of up to a maximum of
$70.0 million under which Cayenta owed Titan approximately $68.4 million as of
March 20, 2000. Cayenta may not use the proceeds of its initial public offering
to pay amounts outstanding under its credit facility with Titan.

    Titan may seek public or private financing for one or more of its commercial
businesses to fund their growth, including through initial public offerings or
spin-offs for any of its segments. Titan cannot guarantee that adequate capital
to fund its growth will be available to Titan or be available on acceptable
terms or that Titan will complete any spin-off of any of its segments.

    TITAN DEPENDS ON GOVERNMENT CONTRACTS FOR A MAJORITY OF ITS REVENUES.

    Titan earns a majority of its total revenues from U.S. government contracts.
Any cancellations or modifications of Titan's significant U.S. government
contracts or subcontracts, or failure by the U.S. government to exercise an
option period relating to those contracts or subcontracts, could hurt Titan's
business, financial condition and results of operations in the short or long
term. Continuing declines in U.S. defense and other federal agency budgets also
may hurt Titan's prospects.


    Titan's revenues from U.S. government business represented approximately 83%
of its total revenues in 1997 and 1998 and 80% of its total revenues for 1999.
This percentage may rise in the future. Although Titan bids for and is awarded
long-term U.S. government contracts and subcontracts, the U.S. government only
funds these contracts on an annual basis, and many of Titan's contracts and
subcontracts include option years. The U.S. government may cancel these
contracts at any time without penalty or may change its requirements, programs
or contract budget, and generally has the right not to exercise option periods.
The U.S. Congress may decline to appropriate funds needed to complete the
contracts awarded to Titan or the prime contractor. On its subcontracts, Titan
generally does not control the prime contractor's allocation of resources. Titan
also depends upon the prime contractor to perform its obligations on the primary
government contract. In addition to contract cancellations and declines in
agency budgets, Titan's prospects may be adversely affected by:


    - budgetary constraints affecting U.S. government spending generally, and
      changes in fiscal policy or available funding;

    - curtailment of the U.S. government's use of technology services providers;

                                       16
<PAGE>
    - the adoption of new laws or regulations;

    - technological developments;

    - U.S. government shutdowns, such as that which occurred during the U.S.
      government's 1996 fiscal year;

    - competition and consolidation in Titan's business areas; and

    - general economic conditions.

These or other factors could cause government agencies to reduce their purchases
under contracts, to exercise their right to terminate contracts or not to
exercise options to renew contracts. Any of these actions could have a material
adverse effect on Titan's business, financial condition and results of
operations.

    GOVERNMENT AUDITS OF TITAN'S GOVERNMENT CONTRACTS COULD CAUSE A MATERIAL
NEGATIVE ADJUSTMENT TO ITS REVENUES.

    Titan's government contracts are subject to cost audits by the government.
These audits may occur several years after completion of the audited work.
Audits may result in a recalculation of contract revenues or result in the
government refusing to reimburse some of Titan's contract costs and fees.
Generally, Titan resolves audit issues by negotiation without material
adjustments. However, in the future, Titan could have a material adjustment to
revenue as a result of an audit, including an audit of one of the companies
Titan has recently acquired. Before Titan acquired them, some of its recently
acquired companies did not impose internal controls as rigorous as those Titan
imposes on the government contracts it performs. As part of the integration
process, Titan seeks to apply its policies throughout the acquired companies.

    TITAN'S OPERATING MARGINS MAY DECLINE UNDER ITS FIXED-PRICE CONTRACTS IF IT
FAILS TO ESTIMATE ACCURATELY THE RESOURCES NECESSARY TO SATISFY ITS OBLIGATIONS.

    Some of Titan's contracts are fixed-price contracts under which Titan bears
the risk of any cost overruns. Its profits are adversely affected if its costs
under a contract exceed the assumptions it used in bidding for these contracts.

    TITAN IS NOT ABLE TO GUARANTEE THAT IT WILL RETAIN ITS CONTRACTS WITH THE
U.S. GOVERNMENT AND SUBCONTRACTS UNDER U.S. GOVERNMENT PRIME CONTRACTS IN ANY
COMPETITIVE REBIDDING PROCESS.

    Upon expiration of a U.S. government contract or subcontract under U.S.
government prime contracts, if the government customer requires further services
of the type provided in the contract, there is frequently a competitive
rebidding process. Titan cannot guarantee that it, or the prime contractor, will
win any particular bid, or that it will be able to replace business lost upon
expiration or completion of a contract. Further, all U.S. government contracts
are subject to protest by competitors. The unexpected termination of one or more
of Titan's significant contracts could result in significant revenue shortfalls.
The termination or non-renewal of any of its significant contracts, short-term
revenue shortfalls, the imposition of fines or damages, or Titan's suspension or
debarment from bidding on additional contracts could have a material adverse
effect on its business, financial condition and results of operations.

    MANY OF TITAN'S U.S. GOVERNMENT CUSTOMERS SPEND THEIR PROCUREMENT BUDGETS
THROUGH GSA SCHEDULE CONTRACTS, AND TITAN IS REQUIRED TO COMPETE FOR POST-AWARD
ORDERS.

    Budgetary pressures and reforms in the procurement process have caused many
U.S. government customers increasingly to purchase goods and services through
"indefinite delivery, indefinite quantity" contracts, General Services
Administration, or GSA, Schedule contracts and other multiple award or
government-wide acquisitions contract vehicles. Titan's failure to compete
effectively in this

                                       17
<PAGE>
procurement environment could have a material adverse effect on its business,
financial condition and results of operations. These contract vehicles have
resulted in increased competition and pricing pressure and required Titan to
make sustained post-award efforts to realize revenues under the relevant
contract. Titan cannot guarantee that it will continue to increase revenues or
otherwise sell successfully under these contract vehicles.

    TITAN MAY BE LIABLE FOR PENALTIES UNDER A VARIETY OF PROCUREMENT RULES AND
REGULATIONS, AND CHANGES IN GOVERNMENT REGULATIONS COULD ADVERSELY AFFECT ITS
BUSINESS.

    Titan's defense, government and commercial businesses must comply with and
are affected by various government regulations. Among the most significant
regulations are the following:

    - the Federal Acquisition Regulations, which comprehensively regulate the
      formation, administration and performance of government contracts;

    - the Truth in Negotiations Act, which requires certification and disclosure
      of all cost and pricing data in connection with contract negotiations;

    - the Cost Accounting Standards, which impose accounting requirements that
      govern Titan's right to reimbursement under certain cost-based government
      contracts; and

    - laws, regulations and Executive Orders restricting the use and
      dissemination of information classified for national security purposes and
      the exportation of certain products and technical data.

These regulations affect how Titan and its customers do business and, in some
instances, impose added costs on its businesses. Any changes in applicable laws
could adversely affect the financial performance of the business affected by the
changed regulations. Any failure to comply with applicable laws could result in
contract termination, price or fee reductions or suspension or debarment from
contracting with the U.S. government.

    TITAN'S FAILURE TO RETAIN QUALIFIED TECHNICAL AND MANAGEMENT PERSONNEL COULD
ADVERSELY AFFECT ITS FINANCIAL PERFORMANCE.

    Titan needs to maintain its workforce of highly qualified technical and
management personnel for each of its business segments, including its engineers,
computer programmers and personnel with security clearances required for
classified work. In addition, Titan's future success will depend in part on its
ability to identify, recruit and retain additional qualified personnel,
including individuals with security clearances required for classified work. The
loss of any key personnel could negatively affect its business, financial
condition and results of operations. Titan's employees generally have many other
job opportunities, and there is intense competition for their services.
Consequently, Titan strives to maintain an entrepreneurial work environment and
provide financial incentives to attract and retain its key personnel. Titan
cannot guarantee that it will be able to continue to attract and retain
personnel with the advanced technical and security clearance qualifications
necessary for the development of its business.

    TITAN COMPETES IN HIGHLY COMPETITIVE MARKETS AGAINST MANY COMPANIES THAT ARE
LARGER, BETTER FINANCED AND BETTER KNOWN THAN TITAN.

    Titan's businesses operate in highly competitive markets. Many of Titan's
competitors are larger, better financed and better known companies who may
compete more effectively. Titan believes it must continue to expand its defense
and government information technology businesses so that it can remain price
competitive and compete for larger contracts. For that reason, Titan is
continuing to look for acquisition candidates. Titan's commercial businesses
compete against other technologies as well as against companies with similar
products. In order to remain competitive, Titan must invest to keep its products
technically advanced and compete on price and on value added to its customers.
Titan's ability

                                       18
<PAGE>
to compete may be adversely affected by limits on its capital resources and its
ability to invest in maintaining and expanding its market share. Any adverse
financial developments could make Titan a less effective competitor.

    TITAN IS SUBJECT TO RISKS ASSOCIATED WITH ITS ACQUISITIONS OF OTHER
COMPANIES.

    Since January 1, 1998, Titan has acquired ten defense information technology
companies as part of the consolidation strategy for its defense and government
information technology businesses. Five of these ten transactions were
structured as stock-for-stock pooling of interests transactions. In addition,
since January 1, 1999, Titan has acquired four information technology services
and solutions companies as part of Cayenta's development of its total services
provider offering. The acquisition and integration of new companies involves
risk. The integration of acquired businesses may be costly and may result in a
decrease in its revenues or a decrease in the value of its common stock for the
following reasons, among others:

    - Titan may need to divert more management resources to integration than it
      planned, which may adversely affect its ability to pursue other more
      profitable activities;

    - the difficulties of integration may be increased by the necessity of
      coordinating geographically separated organizations, integrating personnel
      with disparate business backgrounds and combining different corporate
      cultures;

    - Titan may not eliminate as many redundant costs as it anticipated in
      selecting its acquisition candidates; and

    - one or more of Titan's acquisition candidates also may have liabilities or
      adverse operating issues that Titan failed to discover through its
      diligence prior to the acquisition.

Consequently, Titan's recent acquisitions may not improve its business,
financial condition and results of operations in the short-term or long-term as
it expects them to do.

    Titan intends to continue to look for complementary businesses or
technologies to acquire so that it can expand its core businesses. However,
Titan may not find any more attractive candidates or may find that the
acquisition terms are not favorable to it. In addition, Titan may compete with
other companies for these acquisition candidates. Instability in the U.S.
securities markets and volatility in its stock price may make acquisitions with
Titan stock more expensive. Titan also may not adequately assess the risks
inherent in a particular acquisition candidate or correctly assess the
candidate's potential contribution to its financial performance. Accordingly,
Titan's acquisition strategy may not improve its overall business, financial
condition and results of operations, and could weaken them.

    TITAN MAY INCUR SIGNIFICANT COSTS IN PROTECTING ITS INTELLECTUAL PROPERTY.

    As a policy, Titan seeks to protect its proprietary technology and
inventions through patents, copyrights, trade secret law and other legal
protections. While Titan's patent portfolio is valuable, its financial success
ultimately depends upon its ability to deliver products and services that meet
customer needs, not on intellectual property laws. Titan may, however, incur
significant expense both in protecting its intellectual property and in
depending or assessing claims with respect to intellectual property owned by
others. Any patent or other infringement litigation by or against Titan could
have an adverse effect on its business, financial condition and results of
operations. Titan also could be forced to modify or abandon one or more planned
or current products based upon its assessment of intellectual property risks or
actual or threatened claims by other companies.

    On January 6, 2000, Ion Beam Applications s.a., a Belgian corporation, and
some of its U.S. subsidiaries filed an action for declaratory judgment in a
federal court in Virginia against Titan relating to its patent for its SureBeam
technology. The action attacks the validity of Titan's patent, seeks a
declaration that Ion Beam Applications and its customers have not infringed any
of the 62 claims in

                                       19
<PAGE>
Titan's patent, and alleges that Titan has engaged in unfair competition and
that Titan's conduct constitutes patent misuse. Titan intends to vigorously
defend its patent position. A finding in favor of Ion Beam Applications in this
action could adversely affect Titan's business, financial condition and results
of operations by reducing the growth of its Titan Scan business segment and
preventing Titan from generating the revenues that it expects from food
pasteurization.

    TITAN'S QUARTERLY AND ANNUAL FINANCIAL PERFORMANCE AND STOCK PRICE HAVE
HISTORICALLY FLUCTUATED AND MAY CONTINUE TO FLUCTUATE SIGNIFICANTLY IN THE
FUTURE.

    Titan's revenues are affected by factors such as the unpredictability of
sales and contracts awards due to the long procurement process for most of its
products and services, defense, intelligence and government information
technology budgets, competition and general economic conditions. Titan's product
mix and unit volume, its ability to keep expenses within budgets, its
distribution channels and its pricing affect its gross margins. These factors
and other risk factors described in this proxy statement/prospectus may
adversely affect Titan's financial performance within a period and cause its
financial results to fluctuate significantly on a quarterly or annual basis.
Consequently, Titan does not believe that comparison of its financial
performance from period to period is necessarily meaningful or predictive of its
likely future performance. It is possible that in some future quarter or
quarters Titan's operating results will be below the expectations of public
market analysts or investors. If so, the market price of Titan's common stock
may decline significantly.


    From time to time, there may be significant volatility in the market price
for Titan's common stock. Over the past three years, the market price of Titan's
common stock has fluctuated over a wide range. From January 1, 1999 through
May 19, 2000, the highest sale price of its common stock on the New York Stock
Exchange was $60.50 and the lowest sale price of its common stock was $4.75. A
number of factors involving Titan and its industry could contribute to future
fluctuations in its stock price, including the risk factors described in this
proxy statement/prospectus.


    RISKS OF TITAN'S INTERNATIONAL OPERATIONS, INCLUDING ECONOMIC CONDITIONS IN
EMERGING MARKETS, COULD ADVERSELY AFFECT THE PROSPECTS OF ITS COMMERCIAL
COMMUNICATIONS BUSINESS.

    Titan sells commercial communications products and services primarily in
developing countries. Its revenues from sales of these products and services in
foreign countries represented 5% of its total revenues for the year ended
December 31, 1999. Titan expects its revenues from these activities in foreign
countries to increase. Although Titan generally sells commercial communications
products and services in U.S. dollars, currency devaluations and adverse market
conditions in emerging markets have negatively affected demand for its
commercial communications products and services and, consequently, its revenues
for this segment. Titan's commercial communications products generally require
substantial capital investments, and its potential customers have not had the
capital resources to make these investments. Titan has assisted its established
marketing partner in Indonesia by providing trade credit that has subsequently
been extended with a final installment due in September 2000. Because of market
conditions in Indonesia and other factors, there is a risk that its customer in
Indonesia may not be able to pay this debt in accordance with the extended
terms. Further, Titan does not have the capital resources or tolerance of risk
to finance the purchase of its commercial communications products and therefore
relies upon its customers' abilities to obtain such financing. As a result,
revenues in this group may be adversely affected by economic conditions in
emerging markets and the unavailability of financing on reasonable terms. Titan
also is increasingly seeking opportunities to capture operating revenues from
use of its systems to provide telephony services. These services generally are
billed in U.S. dollars but in the future may be billed in local currency. Titan
does not believe that its international operations currently subject it to
material risks from fluctuations in currency exchange rates. However, as Titan
increases its commercial communications activities in foreign countries, its
risks from fluctuations in currency exchange rates could increase.

                                       20
<PAGE>
    Selling products or services in international markets also entails other
market, economic, cultural, legal and political risks, conditions and expenses.
These risks include:

    - trade barriers;

    - export and import restrictions and other applicable laws;

    - political and economic instability;

    - difficulties in collecting amounts owed to Titan; and

    - difficulties in managing overseas employees and contractors.

Any one of these factors or other international business risks could adversely
affect Titan's financial performance.

    TITAN'S OPERATING RESULTS MAY SUFFER IF A SIGNIFICANT NUMBER OF ITS U.S.
NAVY CONTRACTS ARE DELAYED OR CANCELED.

    A significant percentage of Titan's products and services are predominately
sold and performed under contracts with various parts of the U.S. Navy or with
prime contractors to the U.S. Navy. Although these various parts of the U.S.
Navy are subject to common budgetary pressures and other factors, Titan's
various U.S. Navy customers exercise independent purchasing decisions. However,
because of such concentration of its contracts, Titan is vulnerable to adverse
changes in its business, financial condition and results of operations if a
significant number of its U.S. Navy contracts and subcontracts are
simultaneously delayed or canceled for budgetary or other reasons.

    THE COVENANTS IN TITAN'S EXISTING CREDIT FACILITY RESTRICT ITS FINANCIAL AND
OPERATIONAL FLEXIBILITY, AND IT IS LIKELY THAT ITS ANTICIPATED REPLACEMENT
CREDIT FACILITY WILL CONTAIN SIMILAR OR MORE RESTRICTIVE COVENANTS.

    Titan's existing credit facility contains covenants that restrict, among
other things, its ability to borrow money, make particular types of investments
or other restricted payments, swap or sell assets, merge or consolidate or make
acquisitions. An event of default under its credit facility could allow the
lenders to declare all amounts outstanding to be immediately due and payable.
Titan has pledged substantially all of its consolidated assets and the stock of
its subsidiaries to secure the debt under its credit facility. If the amounts
outstanding under the credit facility were accelerated, the lenders could
proceed against Titan's consolidated assets and the stock of its subsidiaries.
Any event of default, therefore, could have a material adverse effect on its
business. Titan's credit facility also requires it to maintain specified
financial ratios. Titan's ability to meet these financial ratios can be affected
by events beyond its control, and Titan cannot assure you that it will meet
those ratios. Titan also may incur future debt obligations that might subject it
to restrictive covenants that could affect its financial and operational
flexibility or subject it to other events of default.

    TITAN'S OPERATING RESULTS MAY BE ADVERSELY AFFECTED BY DISRUPTIONS IN ITS
SUPPLY OF PRODUCTS AND COMPONENTS OR SERVICES.

    Because its internal manufacturing capacity is limited, Titan uses contract
manufacturers. While it uses care in selecting its manufacturers, this
arrangement gives Titan less control over the quality and price of products or
components than if it manufactured them. In some cases, Titan obtains products
from a sole supplier or a limited group of suppliers. Consequently, Titan risks
disruptions in its supply of key products and components if its suppliers fail
or are unable to perform because of strikes, natural disasters, financial
condition or other factors. Any material supply disruptions could adversely
affect its business, financial condition and results of operations as well as
its ongoing product cost structure.

                                       21
<PAGE>
    TITAN'S BUSINESS IS SUBJECT TO SIGNIFICANT ENVIRONMENTAL REGULATION.

    Titan is subject to environmental and safety laws and regulations governing
the uses, storage and disposal of hazardous substances or waste and imposing
liability for the cleanup of contamination from these substances. Titan cannot
completely eliminate the risk of contamination or injury from these substances
or waste, and, in the event of such an incident, Titan could be held liable for
any damages that result. From time to time, Titan has been notified of
violations of government and environmental regulations. Titan attempts to
correct these violations promptly without any material impact on Titan's
operations. In addition, Titan may be required to incur significant additional
costs to comply with environmental laws and regulations in the future. These
costs, and any future violations or liability under environmental laws or
regulations, could have a material adverse effect on Titan's business, financial
condition and results of operations.

    TITAN DOES NOT ANTICIPATE THAT IT WILL PAY DIVIDENDS ON ITS COMMON STOCK.

    Titan has not paid cash dividends on its common stock within the past three
years and does not anticipate that it will pay cash dividends in the foreseeable
future. Titan may pay cash dividends only if it complies with financial tests
and other restrictions contained in agreements relating to its indebtedness.

    PROVISIONS IN TITAN'S CERTIFICATE OF INCORPORATION AND BYLAWS AND IN
DELAWARE LAW COULD DISCOURAGE TAKEOVER ATTEMPTS TITAN OPPOSES EVEN IF TITAN'S
STOCKHOLDERS MIGHT BENEFIT FROM A CHANGE IN CONTROL OF TITAN.

    Provisions in Titan's certificate of incorporation and bylaws and in the
Delaware General Corporation Law may make it difficult and expensive for a third
party to pursue a takeover attempt Titan opposes even if a change in control of
Titan would be beneficial to the interests of its stockholders. Titan's bylaws
permit its stockholders to take action by written consent instead of at a
meeting and to nominate directors or bring other business before stockholder
meetings only if they comply with advance notice and other procedural
requirements in its bylaws. Titan's board of directors currently has the
authority under its certificate of incorporation to issue up to 2,500,000
authorized shares of Titan preferred stock in one or more series and to fix the
powers, preferences and rights of each series without stockholder approval. The
ability to issue preferred stock could discourage unsolicited acquisition
proposals or make it more difficult for a third party to gain control of Titan,
or otherwise could adversely affect the market price of Titan's common stock.
Further, as a Delaware corporation, Titan is subject to section 203 of the
Delaware General Corporation Law. This section generally prohibits Titan from
engaging in mergers and other business combinations with stockholders that
beneficially own 15% or more of its voting stock, or with their affiliates,
unless Titan's directors or stockholders approve the business combination in the
prescribed manner.

    TITAN HAS ADOPTED A SHAREHOLDER RIGHTS PLAN WHICH COULD DISCOURAGE HOSTILE
ACQUISITIONS OF CONTROL IN WHICH ITS STOCKHOLDERS MAY WISH TO PARTICIPATE.

    In 1995, Titan's board of directors adopted a "poison pill" shareholder
rights plan, which may discourage a third party from making a proposal to
acquire Titan which Titan has not solicited or does not approve, even if the
acquisition would be beneficial to its stockholders. As a result, Titan's
stockholders who wish to participate in such a transaction may not have an
opportunity to do so. Under Titan's rights plan, preferred share purchase
rights, which are attached to its common stock, generally will be triggered upon
the acquisition, or actions that would result in the acquisition, of 15% or more
of its common stock by any person or group. If triggered, these rights would
entitle its stockholders other than the acquiror to purchase, for the exercise
price, shares of its common stock having a market value of two times the
exercise price. In addition, if a company acquires Titan in a merger or other
business combination not approved by the board of directors, these rights will
entitle Titan's stockholders other than the acquiror to purchase, for the
exercise price, shares of the common stock of the acquiring company having a
market value of two times the exercise price.

                          THE AVERSTAR SPECIAL MEETING

GENERAL


    This proxy statement/prospectus, together with a notice of special meeting
and a form of proxy, is being provided to AverStar stockholders in connection
with the solicitation of proxies by the AverStar board of directors for use at a
special meeting of AverStar stockholders to be held on June 26, 2000, at
10:30 a.m., eastern time, at the offices of AverStar at 23 Fourth Avenue,
Burlington, Massachusetts 01803, or at any adjournment, postponement or
rescheduling of that meeting.



    This proxy statement/prospectus and the accompanying notice of special
meeting and form of proxy are first being mailed to stockholders of AverStar
around May 26, 2000.


MATTERS TO BE CONSIDERED

    The special meeting of stockholders is being held so that AverStar
stockholders may consider and vote on adoption of the merger agreement and
approval of the merger and the other transactions contemplated by the merger
agreement.

    AverStar stockholders also will be asked to act on any other matters that
may properly come before the meeting.

RECOMMENDATION OF THE AVERSTAR BOARD OF DIRECTORS

    THE AVERSTAR BOARD OF DIRECTORS HAS APPROVED UNANIMOUSLY THE MERGER
AGREEMENT, THE PROPOSED MERGER AND OTHER TRANSACTIONS RELATED TO THE MERGER AND
CONTEMPLATED BY THE MERGER AGREEMENT. THE AVERSTAR BOARD OF DIRECTORS BELIEVES
THAT THE MERGER IS IN THE BEST INTERESTS OF, AND THAT THE TERMS OF THE MERGER
ARE FAIR TO, AVERSTAR AND ITS STOCKHOLDERS. THE AVERSTAR BOARD RECOMMENDS
UNANIMOUSLY THAT AVERSTAR STOCKHOLDERS VOTE "FOR" THE ADOPTION OF THE MERGER
AGREEMENT AND APPROVAL OF THE MERGER AND THE OTHER TRANSACTIONS CONTEMPLATED BY
THE MERGER AGREEMENT.

RECORD DATE AND VOTE REQUIRED


    The AverStar board of directors has fixed May 19, 2000 as the record date
for determining the AverStar stockholders who are entitled to notice of and to
vote at the special meeting. Therefore, only stockholders of record at the close
of business on the record date will receive notice of, and be able to vote at,
the special meeting of AverStar stockholders.



    At the close of business on the record date, there were 5,958,125 shares of
AverStar common stock outstanding and entitled to a vote, held by 1,203 record
holders. A majority of these shares must be represented, in person or by proxy,
at the special meeting in order to constitute a quorum. A quorum must be present
before a vote can be taken on the adoption of the merger agreement, or any other
matter except adjournment or postponement of the meeting due to the absence of a
quorum. Abstentions, but not shares held in AverStar's treasury, will be counted
for purposes of determining the presence of a quorum at the special meeting.



    At the close of business on the record date, there were 922,136 shares of
AverStar non-voting common stock outstanding, held by 5 record holders. These
shares are not entitled to vote on any matters at the special meeting and will
not be counted for purposes of determining the presence of a quorum at the
special meeting.


    Each share of AverStar voting common stock entitles its holder to cast one
vote on each matter submitted to a vote at the special meeting. For the merger
to be approved under Delaware law and AverStar's certificate of incorporation,
at least a majority of the outstanding shares of AverStar voting common stock on
the record date must be voted for the adoption of the merger agreement. In the
event that stockholders are asked to vote on a proposal to adjourn or postpone
the special meeting to

                                       24
<PAGE>
permit solicitation of additional proxies, approval of that proposal would
require the affirmative vote of at least a majority of the shares of AverStar
voting common stock present in person or represented by proxy at the meeting.


    As of May 19, 2000, 2,062,168 of the outstanding shares of AverStar common
stock, which represented approximately 25.3% of the AverStar common stock
outstanding and approximately 28.5% of the AverStar voting common stock, were
beneficially owned by directors and executive officers of AverStar.


    The AverStar Principal Stockholders, who collectively owned approximately
31.3% of AverStar's outstanding voting common stock as of the record date, have
signed an agreement to vote their shares in favor of adoption of the merger
agreement and approval of the merger and the other transactions contemplated by
the merger agreement. Each of these stockholders also has given Titan an
irrevocable proxy authorizing Titan to vote the stockholder's shares in favor of
adoption of the merger agreement and approval of the merger and the other
transactions contemplated by the merger agreement. See "Terms of the Merger
Agreement and Related Transactions--AverStar Voting Agreement" for more
information about this voting agreement.

PROXIES

    This proxy statement/prospectus is being furnished to AverStar stockholders
in connection with the solicitation of proxies by the AverStar board of
directors for use at the special meeting of AverStar stockholders. It is
accompanied by a form of proxy.

    AverStar stockholders should complete, sign and return the form of proxy if
they will not be able to attend the special meeting in person. A stockholder who
submits a proxy and later changes his or her mind as to the vote, or decides to
attend the meeting in person, may revoke the proxy at any time before the vote
at the special meeting by (x) notifying the corporate secretary of AverStar in
writing of the revocation or (y) completing, signing and returning a proxy with
a later date. In addition, an AverStar stockholder may revoke a prior proxy by
attending the special meeting and voting in person. However, attendance at the
special meeting by an AverStar stockholder who has signed a proxy but does not
provide a notice of revocation or request to vote in person is not sufficient to
revoke that proxy.

    Written notices of revocation of proxies and other communications relating
to proxies should be addressed to:


                   AverStar, Inc.
                   23 Fourth Avenue
                   Burlington, Massachusetts 01803
                   Attn: Carol Doherty


    All shares of AverStar stock entitled to vote represented at the special
meeting of AverStar stockholders by properly executed proxies that are received
prior to or at the meeting and not revoked before the vote at the special
meeting will be voted at the meeting as directed by the stockholders in the
proxies for such shares. If a properly executed proxy is returned but contains
no voting instructions, the shares of AverStar common stock represented by the
proxy will be voted "FOR" adoption of the merger agreement and approval of the
merger and the other transactions contemplated by the merger agreement. In the
event that AverStar stockholders are asked to vote on a proposal to adjourn or
postpone the meeting to permit the solicitation of additional proxies and no
directions on this proposal are indicated, proxies that indicate a vote in favor
of adoption of the merger agreement will be voted "FOR" the proposal to postpone
or adjourn, proxies that indicate a vote against adoption of the merger
agreement will be voted "AGAINST" the proposal to postpone or adjourn, and
proxies that

                                       25
<PAGE>
abstain from a vote on adoption of the merger agreement will be voted "FOR" the
adjournment or postponement.

    ADOPTION OF THE MERGER AGREEMENT AND APPROVAL OF THE MERGER AND THE OTHER
TRANSACTIONS CONTEMPLATED BY THE MERGER AGREEMENT REQUIRES THE AFFIRMATIVE VOTE
OF A MAJORITY OF THE OUTSTANDING SHARES OF AVERSTAR VOTING COMMON STOCK ON THE
RECORD DATE. ACCORDINGLY, ABSTENTIONS AND FAILURES TO VOTE WILL HAVE THE SAME
EFFECT AS VOTES AGAINST ADOPTION OF THE MERGER AGREEMENT AND APPROVAL OF THE
MERGER AND THE OTHER TRANSACTIONS CONTEMPLATED BY THE MERGER AGREEMENT.
THEREFORE, THE AVERSTAR BOARD OF DIRECTORS URGES ALL AVERSTAR STOCKHOLDERS TO
COMPLETE, DATE AND SIGN THE ACCOMPANYING PROXY AND RETURN IT PROMPTLY IN THE
PRE-ADDRESSED, POSTAGE-PAID ENVELOPE PROVIDED FOR THAT PURPOSE.

    If any other matters are properly presented for consideration at the special
meeting, the persons named in the enclosed form of proxy will have the
discretion to vote on those matters using their best judgment.

    All expenses incurred in connection with the solicitation of proxies,
including the cost of preparing and mailing the proxy materials, are
approximately $100,000 and will be paid by AverStar. If the merger is not
completed, AverStar and Titan have agreed to share equally certain costs,
including costs of printing, filing and mailing this proxy statement/prospectus
and the registration statement of which it is a part, up to $100,000, and Titan
shall bear all such costs and expenses in excess of $100,000. Directors,
officers and employees of AverStar may solicit proxies in person or by
telephone, mail, facsimile or other means. These directors, officers and
employees will not be separately compensated for soliciting proxies.

    PLEASE DO NOT SEND STOCK CERTIFICATES WITH YOUR PROXY CARD.

AVAILABILITY OF INDEPENDENT AUDITORS

    Ernst & Young LLP has acted as AverStar's independent auditors since 1995.
Representatives of Ernst & Young LLP familiar with AverStar are expected to
attend the special meeting and to be available to answer appropriate questions
and will have an opportunity to make a statement if they should desire to do so.

                                       26

                                   THE MERGER

    The discussion in this proxy statement/prospectus of the merger and the
principal terms of the merger agreement is qualified in its entirety by
reference to the merger agreement, which is attached to this proxy
statement/prospectus as Appendix A and is incorporated in this document by
reference.

GENERAL

    Under the terms of the merger agreement, V T Acquisition Corp., a wholly
owned subsidiary of Titan, will be merged with and into AverStar at the
effective time of the merger. AverStar will be the surviving corporation in the
merger and will become a wholly owned subsidiary of Titan.

    At the effective time of the merger, all issued and outstanding shares of
AverStar common stock will be converted into the right to receive the number of
shares of Titan common stock calculated as described below. Titan will not issue
fractional shares of its common stock in the merger. Instead, fractional shares
will be rounded up to the nearest whole share of Titan common stock. After the
conversion of all classes of AverStar common stock into one class of common
stock as required by AverStar's certificate of incorporation and stockholders'
agreement, the number of shares of Titan common stock AverStar stockholders will
be entitled to receive will depend on the exchange ratio of Titan common stock
to AverStar common stock. The exchange ratio has not been fixed in the merger
agreement, but will be calculated at the time of the merger in accordance with a
formula contained in the merger agreement. Under this formula, the exchange
ratio will be based on the average of the closing sale prices of the Titan
common stock on the NYSE for the ten consecutive trading days ending two trading
days immediately before the merger closing date.

    At the effective time of the merger, Titan will assume all outstanding
AverStar stock options. Each assumed option will be converted in the merger into
an option to purchase shares of Titan common stock using the same exchange ratio
which is applicable to AverStar common stock in the merger. Except for the
number of shares issuable upon exercise of such options and the option exercise
prices, which will be adjusted based on the exchange ratio, the assumed options
will remain subject to the same terms and conditions that were in effect before
the merger. The exercise price per share of Titan common stock issuable under
the assumed options will equal the exercise price per share of AverStar common
stock issuable under the applicable option at the effective time of the merger
divided by the exchange ratio, rounded to the nearest whole cent. The option
conversion will not result in accelerated vesting of any assumed options or
otherwise affect the vesting schedules in effect before the merger for the
assumed options.

BACKGROUND OF THE MERGER

    AVERSTAR CONSIDERATION OF STRATEGIC ALTERNATIVES.  AverStar has pursued a
strategy of internal growth, through leveraging both its position in IT
assurance and its expertise and reputation in the federal IT market, and
external growth, through the acquisition of complimentary companies that operate
in defined vertical market niches. As part of its external growth strategy,
AverStar's current management has completed a series of strategic acquisitions
of five well established IT companies. In order to position itself to continue
to benefit from the consolidation in the federal IT industry, AverStar pursued
an initial public offering of its common stock during the summer of 1999.
Because of adverse market conditions, however, AverStar decided not to complete
its initial public offering. AverStar continued to explore all of its strategic
opportunities, including combining with a larger company in the federal IT
industry, and continuing to grow and develop AverStar's business.

    TITAN ACQUISITION STRATEGY.  In recent years, developments in government
procurement policies and other factors have contributed to substantial
consolidation in the government information technology industry, as larger
companies have acquired smaller companies without the broad capabilities needed
to compete effectively for government contracts. Titan has pursued a policy of
supplementing the internal

                                       27
<PAGE>
growth in its defense and government information technology business with an
active program of strategic acquisitions to take advantage of growth
opportunities from this ongoing consolidation. Since January 1, 1998, Titan has
acquired ten defense information technology companies as part of its
consolidation strategy. In implementing its strategy, Titan seeks acquisition
candidates it believes are capable of bringing strategic advantages, earnings
and strong management resources to the combined company.

    CHRONOLOGY OF EVENTS LEADING UP TO EXECUTION OF THE MERGER AGREEMENT.

    On January 20, 2000, Gene Ray, Titan's Chairman, President and Chief
Executive Officer, called Michael Alexander, AverStar's Chairman and Chief
Executive Officer, and requested a meeting among Mr. Ray, Mr. Alexander and Eric
DeMarco, Titan's Chief Financial Officer in New York on February 10, 2000.
Mr. Ray said he could not discuss the reason for the meeting and would explain
at the meeting. Mr. Alexander asked if Joe Saponaro, AverStar's President,
should also attend the meeting and Mr. Ray responded that it would probably be
helpful.

    Early the next week, Mr. Ray's assistant called Mr. Alexander to reschedule
the meeting for February 14, 2000, and to ask for a suggestion of a meeting
place. Mr. Alexander suggested the offices of AverStar's counsel.

    On February 14, 2000, Mr. Alexander and Mr. Saponaro met with Mr. Ray and
Nick Costanza, Titan's in-house counsel at the offices of Swidler Berlin Shereff
Friedman, LLP, counsel to AverStar, in New York City. Mr. DeMarco participated
by telephone. Swidler Berlin Shereff Friedman, LLP attended parts of the
meeting. Mr. Ray began the meeting by stating that Titan would like to explore
the possibility of a business combination with AverStar, particularly if it
could be structured as a tax-free exchange of stock accounted for as a pooling
of interests. He apologized for not disclosing the purpose of the meeting in
advance, explaining that Titan needed to close its preferred stock offering
prior to beginning any such discussions.

    AverStar and Titan spent the next ten hours or so exchanging and clarifying
financial numbers on both the companies. Ultimately, Mr. Ray made an offer of
$185 million for the enterprise value of AverStar. Mr. Alexander and
Mr. Saponaro responded that AverStar would require an enterprise value of at
least $200 million to move forward under the structure of the proposed deal, and
that AverStar would require a collar around Titan's stock to protect that
enterprise value during the time period between the signing of a definitive
agreement and the closing of a merger. Titan agreed to AverStar's requests
subject to AverStar agreeing to a 10% holdback of shares of Titan's common stock
until the expiration of the normal representations and warranties. AverStar
agreed to a holdback of not longer than 90 days.

    AverStar and Titan worked through the evening and into the next day,
February 15, to craft an exclusivity agreement and a term sheet which were
consistent with the terms discussed. On February 15, 2000, AverStar's board of
directors approved the signing of a 30-day exclusivity agreement with Titan,
including appropriate break-up fees, based upon an accompanying unsigned,
non-binding term sheet.

    On February 17, 2000, Titan's board of directors met to review the proposed
terms of the merger on a preliminary basis.

    On February 24, 2000, AverStar engaged Ernst & Young LLP to perform certain
limited due diligence procedures at Titan in connection with the proposed
merger.

    Over the next six weeks, Titan and AverStar performed due diligence
investigations of each other and, with the assistance of Swidler Berlin Shereff
Friedman, LLP, CS First Boston, Titan's financial adviser, Nick Costanza,
Titan's in-house counsel, and Hogan & Hartson L.L.P., counsel to Titan,
negotiated a definitive merger agreement. The merger agreement contained
essentially the same terms as contemplated by the term sheet, with the following
exceptions:

                                       28
<PAGE>
    - When the merger agreement was almost fully negotiated and the parties were
      nearly comfortable with the proposed deal, Titan's common stock
      experienced a significant price increase. On March 22, 2000, Mr. Ray
      called Mr. Alexander to explain that the price increase had caused a
      problem with Titan's investment bankers recommendation of the proposed
      deal to Titan's board of directors. Mr. Ray asked Mr. Alexander to work
      together to devise a solution. Over the next day and a half the parties
      explored several suggested solutions. Titan and its advisers insisted that
      the only acceptable solution was to adjust the midpoint of the collar
      upward, so that the current trading price of Titan would be within the
      collar when the transaction was announced.

    - On March 22, 2000, Titan's board of directors met in a special meeting. At
      this meeting, members of Titan's senior management, together with Hogan &
      Hartson L.L.P. and CS First Boston, reviewed with Titan's board of
      directors, among other things, the financial and legal aspects of the
      transaction, the terms of the merger agreement, the agreement with the
      AverStar Principal Stockholders, and the other matters described below
      under "Titan Reasons for the Merger." After discussion and consideration,
      the Titan board of directors unanimously approved the merger agreement and
      the merger and the issuance of Titan common stock in connection with the
      merger, subject to finalizing certain open points in the merger agreement.

    - On March 23, 2000, Mr. Ray and Bob Lovett of CS First Boston called
      Mr. Alexander to propose a solution to the problem. In exchange for
      raising the midpoint of the collar, Titan offered to increase the
      enterprise value to $205 million. Mr. Alexander responded that he believed
      he could recommend that proposal to AverStar's board of directors if Titan
      would also agree to drop the holdback provision. Later that day, Mr. Ray
      informed Mr. Alexander that Titan would agree to reduce the holdback to
      5%.

    - AverStar's board of directors held a meeting on the evening of March 23,
      2000. Mr. Alexander explained the status of the proposed merger to
      AverStar's board of directors and a lengthy discussion ensued. The Board
      authorized the merger agreement, subject to finalizing certain open points
      in the merger agreement.

    During the day of March 24, 2000, the final provisions of the merger
agreement were negotiated. Titan and AverStar exchanged signatures that evening.

RECOMMENDATION OF AVERSTAR BOARD OF DIRECTORS; AVERSTAR REASONS FOR THE MERGER

    AVERSTAR'S BOARD OF DIRECTORS BELIEVES THAT THE MERGER IS ADVISABLE, FAIR
TO, AND IN THE BEST INTERESTS OF AVERSTAR AND THE AVERSTAR STOCKHOLDERS.
ACCORDINGLY, AVERSTAR'S BOARD OF DIRECTORS HAS UNANIMOUSLY APPROVED THE MERGER
AGREEMENT, UNANIMOUSLY ADOPTED A RESOLUTION DECLARING THE MERGER ADVISABLE AND
UNANIMOUSLY RECOMMENDS THAT AVERSTAR STOCKHOLDERS VOTE "FOR" THE ADOPTION OF THE
MERGER AGREEMENT AND THE APPROVAL OF THE MERGER AND THE TRANSACTIONS
CONTEMPLATED BY THE MERGER AGREEMENT.

    AverStar's board of directors and senior management believe that the
proposed merger will benefit AverStar and our stockholders for the following
reasons:

    - the opportunity for AverStar stockholders to own stock of a publicly
      traded company, with greater resources and a more diversified business;

    - the realization of full value for AverStar's stockholders and a
      significant return to them on their investment, based on the current value
      of the Titan common stock to be issued in the merger;

    - the access to Titan's complimentary base of customers and to broader
      technology and expertise to offer to existing and potential customers;

                                       29
<PAGE>
    - the benefits of consolidation in response to the current market trends in
      the federal IT industry toward larger, multiple award contracts; and

    - the potential opportunities in a larger company for AverStar employees and
      customers.

    At a meeting of AverStar's board of directors held on March 23, 2000, after
due consideration, AverStar's board of directors unanimously:

    - determined that the merger agreement and the proposed merger are fair to,
      and in the best interests of, AverStar and its stockholders;

    - approved the merger agreement, the proposed merger and related
      transactions; and

    - determined to recommend that AverStar's stockholders approve the merger,
      the proposed merger and related transactions.

Accordingly, AverStar's board of directors recommends that you vote FOR the
approval of the proposed merger, the merger agreement and the related
transactions.

    In the course of its deliberations, AverStar's board of directors and senior
management reviewed a number of other factors relevant to the proposed merger.
In particular, AverStar's board of directors considered, among other things:

    - all the proposed benefits described above;

    - information relating to the business, assets, management, competitive
      position, operating performance, trading performance and prospects of each
      of AverStar and Titan, including the prospects of AverStar if it were to
      continue as an independent company;

    - Titan's filings with the Securities and Exchange Commission;

    - the current and historical market prices of Titan's common stock and the
      risks associated with ownership of Titan's common stock;

    - Titan's management presentation;

    - information and advice based on the results of due diligence
      investigations of Titan by members of AverStar's management and legal and
      financial advisors;

    - the capabilities of Titan's management team;

    - the fact that the proposed merger is expected to qualify as a tax free
      reorganization and be accounted for as a pooling of interest;

    - the possibility of other alternatives to the proposed merger to increase
      AverStar stockholder value;

    - the impact of the proposed merger on AverStar's customers, suppliers and
      employees;

    - the likelihood that the proposed merger would be completed; and

    - the terms of the merger agreement, including representations and
      warranties, conditions to closing, rights of termination and provisions
      permitting the AverStar board of directors to terminate the merger
      agreement in response to a third party proposal which the AverStar board
      of directors determines in its good faith judgment to be more favorable to
      the AverStar stockholders than the proposed merger.

                                       30
<PAGE>
    AverStar's board of directors also identified and considered a number of
potentially negative factors in its deliberations concerning the proposed
merger, including:

    - the risk that AverStar's operations might not be successfully integrated;

    - the risk that the merger will not be completed;

    - the risk that the price of Titan's common stock may fall precipitously
      after the merger is completed;

    - the risk that Titan may not grow or remain profitable after the proposed
      merger; and

    - the risk that the potential benefits of the proposed merger might not be
      fully realized.

AverStar's board of directors believes that some of these risks are unlikely to
occur, that AverStar and Titan can avoid or mitigate others, and that, overall,
these risks are outweighed by the potential benefits of the proposed merger.

    In view of the variety of factors considered in connection with its
evaluation of the merger agreement and the proposed merger, AverStar's board of
directors did not find it practical to and did not quantify or otherwise assign
relative weight to the specific factors considered in making its decisions and
recommendations. AverStar's board of directors considered the factors described
above as a whole and, overall, considered the factors to be favorable to and
support its decisions and recommendations. Individual members of AverStar's
board of directors may have given different weight to different factors.

TITAN REASONS FOR THE MERGER

    Titan believes a business combination with AverStar will advance its
strategic objective of taking advantage through acquisitions of growth
opportunities from ongoing consolidation in the commercial and government
information technology industries. Titan expects the combination with AverStar
to offer the following strategic benefits to Titan after the merger:

    - enhancement of Titan's government information technology and commercial
      business revenues;

    - expansion of Titan's government information technology and commercial
      customer bases;

    - broadening of Titan's capability to serve the government information
      technology industry and to compete for new projects;

    - enhancement of Titan's ability to create, build and launch
      technology-based businesses; and

    - strengthening of Titan's ability to develop promising emerging businesses
      in its new Network, Internet and Information Security and Information
      Technology Services business units.

INTERESTS OF AVERSTAR DIRECTORS AND EXECUTIVE OFFICERS IN THE MERGER

    The following AverStar directors and executive officers have interests in
the merger that are different from, or in addition to, the interests generally
of AverStar stockholders:

    - The merger agreement provides that Michael B. Alexander, the Chairman and
      Chief Executive Officer of AverStar, will become a member of the Titan
      board of directors.

    - Michael B. Alexander's and Joseph A. Saponaro's outstanding options to
      purchase 387,831 shares and 116,349 shares of AverStar common stock,
      respectively, will immediately and fully vest upon completion of the
      merger.

                                       31
<PAGE>

    - Upon completion of the merger, holders of certain classes of AverStar
      common stock, including Messrs. Levy and Schulte, will receive
      approximately 386,230 additional shares of AverStar common stock pursuant
      to allocations on certain classes of AverStar common stock required by
      AverStar's certificate of incorporation and stockholders agreement.



    As of May 19, 2000, directors and executive officers of AverStar held a
total of 1,484,629 shares of AverStar common stock and options to purchase
577,539 shares of AverStar common stock. These shares and options will be
converted in the merger into the right to receive shares of Titan common stock
or options to purchase shares of Titan common stock on the same basis as all
other outstanding AverStar shares and options.


    As a result of their interests in the merger, the individuals listed above
may be more likely to vote to approve the merger agreement and the merger than
if they did not hold such interests. The AverStar board of directors was aware
of these interests and considered them, among other matters, in approving the
merger agreement and the transactions contemplated thereby.

STOCKHOLDER APPROVAL REQUIREMENTS

    Under Delaware law, AverStar stockholders must vote to adopt the merger
agreement in order for AverStar to complete the merger. Titan stockholders are
not required to adopt the merger agreement under Delaware law because Titan is
not a constituent corporation in the merger, or under NYSE rules because the
maximum number of shares of Titan common stock which Titan is obligated to issue
in the merger will be less than 20% of the Titan common stock outstanding before
the merger.

ACCOUNTING TREATMENT

    It is intended that the merger be accounted for by Titan as a pooling of
interests under generally accepted accounting principles. This means that Titan
and AverStar will be treated as if they had always been combined for accounting
and financial reporting purposes. It is a condition to the completion of the
merger that the following will occur:

    - AverStar and Titan will receive a letter, dated the merger closing date,
      from AverStar's independent auditors setting forth a statement that
      AverStar's independent auditors, after reasonable investigation, are not
      aware of any fact concerning AverStar or its stockholders or affiliates
      that could preclude Titan from accounting for the merger as a pooling of
      interests. In satisfaction of such condition, such letter from AverStar's
      independent auditors will state that they concur with AverStar
      management's conclusion that certain criteria relating to pooling of
      interests accounting have been met; and

    - Titan and AverStar will receive a letter, dated the merger closing date,
      from Titan's independent accountants stating that the accountants are not
      aware of any fact concerning Titan or any of its affiliates which could
      preclude Titan from accounting for the merger as a pooling of interests,
      and that the merger is eligible to be accounted for as a pooling of
      interests.

LISTING OF TITAN COMMON STOCK ON THE NYSE

    It is a condition to the obligation of Titan and AverStar to complete the
merger that the Titan common stock to be issued under the merger agreement,
including the Titan shares issuable upon exercise of the assumed stock options,
be approved for listing on the NYSE, subject to official notice of issuance.

                                       32

DISSENTERS' RIGHTS

    Both Titan and AverStar are incorporated under the laws of Delaware, and are
therefore governed by the Delaware General Corporation Law. Titan stockholders
are not entitled to dissent from the merger or to exercise appraisal rights
under section 262 of the Delaware General Corporation Law because Titan is not a
constituent corporation in the merger. Under section 262 of the Delaware General
Corporation Law, the stockholders of AverStar are entitled to dissent from the
merger and to exercise appraisal rights in connection with the merger.

    If the merger is consummated, a holder of record of AverStar common stock on
the date of making a demand for appraisal, as described below, will be entitled
to have those shares appraised by the Delaware Court of Chancery under
section 262 of the Delaware General Corporation Law and to receive payment for
the "fair value" of those shares instead of the consideration provided for in
the merger agreement. In order to be eligible to receive this payment, however,
a stockholder must (1) continue to hold his shares through the time of the
merger; (2) strictly comply with the procedures discussed under section 262; and
(3) not vote in favor of the merger. Shares of AverStar common stock outstanding
immediately prior to the effective time of the merger, with respect to which
appraisal shall have been properly demanded in accordance with section 262, will
not be converted into the right to receive shares of Titan common stock in the
merger at or after the effective time of the merger unless and until the holder
of such shares withdraws his demand for such appraisal or becomes ineligible for
such appraisal.

    This proxy statement and prospectus is being sent to all holders of record
of AverStar common stock on the record date for the AverStar special meeting and
constitutes notice of the appraisal rights available to those holders under
section 262.

    The following summary is not a complete statement of section 262 of the
Delaware General Corporation law, and is qualified in its entirety by reference
to section 262 which is incorporated herein by reference, together with any
amendments to the laws that may be adopted after the date of this proxy
statement and prospectus. A copy of section 262 is attached as Appendix C to
this proxy statement/prospectus.

    A holder of AverStar common stock who elects to exercise appraisal rights
under section 262 must deliver a written demand for appraisal of his shares of
AverStar prior to the vote on the merger. The written demand must identify the
stockholder of record and state the stockholder's intention to demand appraisal
of his shares. Voting against approval of the merger, abstaining from voting or
failing to vote with respect to approval of the merger will not constitute a
demand for appraisal within the meaning of section 262. All demands should be
delivered to: AverStar, Inc., 23 Fourth Avenue, Burlington, MA 01803,
Attn: Secretary.

    Only a holder of shares of AverStar common stock on the date of making a
written demand for appraisal who continuously holds those shares through the
time of the merger is entitled to seek appraisal. Demand for appraisal must be
executed by or for the holder of record, fully and correctly, as that holder's
name appears on the holder's stock certificates representing shares of AverStar
common stock. If AverStar common stock is owned of record in a fiduciary
capacity by a trustee, guardian or custodian, the demand should be made in that
capacity. If AverStar common stock is owned of record by more than one person,
as in a joint tenancy or tenancy in common, the demand should be made by or for
all owners of record. An authorized agent, including one or more joint owners,
may execute the demand for appraisal for a holder of record; that agent,
however, must identify the record owner or owners and expressly disclose in the
demand that the agent is acting as agent for the record owner or owners of the
shares.

    A record holder such as a broker who holds shares of AverStar common stock
as a nominee for beneficial owners, some of whom desire to demand appraisal,
must exercise appraisal rights on behalf

                                       33
<PAGE>
of those beneficial owners with respect to the shares of AverStar common stock
held for those beneficial owners. In that case, the written demand for appraisal
should state the number of shares of AverStar common stock covered by it. Unless
a demand for appraisal specifies a number of shares, the demand will be presumed
to cover all shares of AverStar stock held in the name of the record owner.

    BENEFICIAL OWNERS WHO ARE NOT RECORD OWNERS AND WHO INTEND TO EXERCISE
APPRAISAL RIGHTS SHOULD INSTRUCT THE RECORD OWNER TO COMPLY WITH THE STATUTORY
REQUIREMENTS WITH RESPECT TO THE EXERCISE OF APPRAISAL RIGHTS BEFORE THE DATE OF
THE AVERSTAR SPECIAL MEETING.

    Within 10 days after the merger, the surviving corporation in the merger is
required to send notice of the effectiveness of the merger to each stockholder
who prior to the time of the merger has complied with the requirements of
section 262.

    Within 120 days after the merger, the surviving corporation in the merger or
any stockholder who has complied with the requirement of section 262 may file a
petition in the Delaware Court of Chancery demanding a determination of the fair
value of the shares of AverStar common stock held by all stockholders seeking
appraisal. A dissenting stockholder must serve a copy of the petition on
AverStar, as the surviving corporation in the merger. If no petition is filed by
either the surviving corporation or any dissenting stockholder within the
120-day period, the rights of all dissenting stockholders to appraisal will
cease. Stockholders seeking to exercise appraisal rights should not assume that
the surviving corporation will file a petition with respect to the appraisal of
the fair value of their shares or that the surviving corporation will initiate
any negotiations with respect to the fair value of those shares. The surviving
corporation is under no obligation to and has no present intention to take any
action in this regard. Accordingly, stockholders who wish to seek appraisal of
their shares should initiate all necessary action with respect to the perfection
of their appraisal rights within the time periods and in the manner prescribed
in section 262.

    Within 120 days after the time of the merger, any stockholder who has
complied with subsections (a) and (d) of section 262 is entitled, upon written
request, to receive from the surviving corporation in the merger a statement
setting forth the total number of shares of AverStar common stock not voted in
favor of the merger with respect to which demands for appraisal have been
received and the number of holders of those shares. The statement must be mailed
within 10 days after the surviving corporation has received the written request
or within 10 days after the time for delivery of demands for appraisal under
subsection (d) of section 262 has expired, whichever is later.

    If a petition for an appraisal is filed in a timely manner, at the hearing
on that petition the Delaware Court of Chancery will determine which
stockholders are entitled to appraisal rights and will appraise the shares of
AverStar common stock owned by those stockholders. The court will determine the
fair value of those shares, exclusive of any element of value arising from the
accomplishment or expectation of the merger, together with a fair rate of
interest, to be paid, if any, upon the fair value. The Delaware Court of
Chancery may require the stockholders who have demanded appraisal rights for
their shares of AverStar common stock and who hold certificates representing
such shares to submit such certificates to the Register in Chancery for notation
thereon during the pendency of any hearing. The Court of Chancery may dismiss
the proceedings as to any stockholder who fails to comply with any such
directions.

    Stockholders who consider seeking appraisal should consider that the fair
value of their shares under section 262 could be more than, the same as, or less
than, the value of the consideration provided for in the merger agreement
without the exercise of appraisal rights. The Court of Chancery may determine
the cost of the appraisal proceeding and assess it against the parties as the
Court deems equitable. Upon application of a dissenting stockholder, the Court
may order that all or a portion of the expenses incurred by any dissenting
stockholder in connection with the appraisal proceeding

                                       34
<PAGE>
(including, without limitation, reasonable attorney's fees and the fees and
expenses of experts) be charged pro rata against the value of all shares of
AverStar common stock entitled to appraisal. In the absence of a court
determination or assessment, each party bears its own expenses.

    Any stockholder who has demanded appraisal in compliance with section 262
will not, after the merger, be entitled to vote such stock for any purpose or
receive payment of dividends or other distributions, if any, on the AverStar
common stock, except for dividends or distributions, if any, payable to
stockholders of record at a date prior to the merger.

    A stockholder may withdraw a demand for appraisal and accept the Titan
common stock at any time within 60 days after the effective date of merger, or
thereafter may withdraw a demand for appraisal with the written approval of the
surviving corporation in the merger. If an appraisal proceeding is properly
instituted, it may not be dismissed as to any stockholder without the approval
of the Delaware Court of Chancery, and any such approval may be conditioned on
the Court of Chancery's deeming the terms to be just. If, after the merger, a
holder of AverStar common stock who had demanded appraisal for his shares fails
to perfect or loses his right to appraisal, those shares will be treated under
the merger agreement as if they were converted into Titan common stock at the
time of the merger.

CLEARANCE UNDER FEDERAL ANTITRUST LAWS

    Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, the merger
may not be completed until notifications have been given and certain information
has been furnished to the Federal Trade Commission and the Antitrust Division of
the Department of Justice and specified waiting period requirements have been
satisfied. The obligations of Titan and AverStar to complete the merger are
subject to the condition that the applicable waiting period will have expired or
been terminated. Titan and AverStar filed pre-merger notification and report
forms with respect to the merger with the Federal Trade Commission and the
Antitrust Division on April 14, 2000. Satisfaction or termination of the waiting
period requirement with respect to any such filing does not preclude the Federal
Trade Commission, the Antitrust Division or any other party from challenging or
seeking to delay or enjoin the merger on antitrust or other grounds either
before or after the effective time of the merger. There can be no assurance that
such a challenge will not be made or, if made, would not succeed.

FEDERAL INCOME TAX CONSEQUENCES

    The following discussion is a summary of the material U.S. federal income
tax consequences of the merger to a stockholder of AverStar holding shares of
AverStar common stock as a capital asset within the meaning of section 1221 of
the Internal Revenue Code of 1986 at the effective time of the merger.

    This discussion does not address all aspects of federal taxation that may be
relevant to particular stockholders of AverStar in light of their personal
circumstances or to stockholders of AverStar subject to special treatment under
the Internal Revenue Code. Stockholders subject to special treatment include
banks, tax-exempt organizations, insurance companies, dealers in securities or
foreign currencies, stockholders who received their AverStar common stock
through the exercise of employee stock options or otherwise as compensation,
stockholders who are not U.S. persons and stockholders who hold AverStar common
stock as part of a hedge, straddle or conversion transaction. In addition, the
discussion does not address any state, local or foreign tax consequences of the
merger, or the tax consequences of the merger to holders of stock options or
restricted stock.

    This discussion is based on the Internal Revenue Code, the U.S. Department
of Treasury regulations and administrative rulings and court decisions as of the
date of this proxy statement/ prospectus. These sources of legal authority are
all subject to change, possibly with retroactive effects,

                                       35
<PAGE>
and are subject to differing interpretations. Neither Titan nor AverStar has
sought or will seek a ruling from the Internal Revenue Service concerning the
tax consequences of the merger. AverStar stockholders are urged to consult their
tax advisors regarding the tax consequences of the merger to them, including the
effects of U.S. federal, state, local, foreign and other tax laws.

    TAX CONSEQUENCES OF THE MERGER.  One of the conditions of the merger is that
Titan must receive the opinion of Hogan & Hartson L.L.P., counsel to Titan, and
AverStar and the AverStar stockholders must receive the opinion of Swidler
Berlin Shereff Friedman, LLP, counsel to AverStar, that the merger of V T
Acquisition Corp. into AverStar will qualify as a reorganization under
section 368(a) of the Internal Revenue Code, subject to the assumptions,
limitations, qualifications and other considerations described below under
"Considerations with Respect to Opinions." Under such treatment,

        (1) no gain or loss will be recognized by an AverStar stockholder as a
    result of the receipt solely of shares of Titan common stock in exchange for
    the stockholder's AverStar common stock;

        (2) an AverStar stockholder's tax basis in the Titan common stock
    received in the merger will be equal to the stockholder's aggregate tax
    basis in the AverStar common stock immediately before the merger;

        (3) an AverStar stockholder's holding period for Titan common stock
    received in the merger will include the holding period of the AverStar
    common stock for which it was exchanged, assuming such AverStar common stock
    was held as a capital asset on the effective date of the merger; and

        (4) neither Titan nor AverStar will recognize any gain or loss as a
    result of the merger.

    CONSIDERATIONS WITH RESPECT TO OPINIONS.  The tax opinions of Hogan &
Hartson L.L.P. and Swidler Berlin Shereff Friedman, LLP and the foregoing
summary of the U.S. federal income tax consequences of the merger will be and
are subject to assumptions, limitations and qualifications and are based on
current law and, among other things, representations of AverStar and Titan,
including representations made by the respective managements of AverStar and
Titan. Opinions of counsel are not binding on the Internal Revenue Service and
do not preclude the Internal Revenue Service from adopting a contrary position.
In addition, if any of the representations or assumptions underlying the
opinions are inconsistent with the facts relating to the merger and the parties
to the merger, the U.S. federal income tax consequences of the merger could
differ from those described above.

    THIS DISCUSSION IS ONLY A GENERAL SUMMARY OF THE MATERIAL FEDERAL INCOME TAX
CONSEQUENCES OF THE MERGER. THE TAX CONSEQUENCES OF THE MERGER TO AN AVERSTAR
STOCKHOLDER MAY BE DIFFERENT FROM THOSE SUMMARIZED ABOVE, BASED ON THE AVERSTAR
STOCKHOLDER'S INDIVIDUAL SITUATION. THE STOCKHOLDERS OF AVERSTAR ARE STRONGLY
ENCOURAGED TO CONSULT THEIR OWN TAX ADVISORS AS TO THE SPECIFIC TAX CONSEQUENCES
TO THEM OF THE MERGER, INCLUDING TAX RETURN REPORTING REQUIREMENTS, THE
APPLICABILITY AND EFFECT OF FEDERAL, STATE, LOCAL AND OTHER APPLICABLE TAX LAWS,
AND THE EFFECT OF ANY PROPOSED CHANGES IN THE TAX LAWS.

RESTRICTIONS ON RESALE OF TITAN COMMON STOCK BY AFFILIATES

    The issuance of Titan shares to AverStar stockholders in connection with the
merger has been registered under the Securities Act. Such shares may be traded
freely and without restriction by those AverStar stockholders who are not deemed
to be AverStar "affiliates," as that term is defined under the Securities Act,
at the time the merger agreement is submitted for approval by the AverStar
stockholders at the special meeting. An affiliate of AverStar is a person who
directly, or indirectly through one or more intermediaries, controls, is
controlled by or is under common control with

                                       36
<PAGE>
AverStar. Any subsequent transfer of Titan common stock issued in the merger by
any AverStar affiliate will, under existing law, require one of the following:

    - registration of the transfer under the Securities Act;

    - compliance with Rule 145 under the Securities Act, which allows limited
      sales under specified circumstances; or

    - availability of another exemption from registration.

The foregoing restrictions are expected to apply to, among other persons,
directors and executive officers of AverStar and any holders of 10% or more of
the AverStar common stock converted in the merger.

    SEC guidelines regarding qualifying for the pooling of interests method of
accounting also limit sales of shares of the acquiring and acquired companies by
affiliates of either company. SEC guidelines indicate further that the pooling
of interests method of accounting generally will not be challenged on the basis
of sales by affiliates of the acquiring or acquired company if the affiliates do
not dispose of any of the shares of the corporation they own or shares of a
corporation they receive in connection with a business combination during the
period beginning 30 days before the completion of the business combination and
ending when financial results covering at least 30 days of post-merger
operations of the combined entity have been published in accordance with SEC
Accounting Series Release No. 135.

    Titan has agreed in the merger agreement to use its reasonable best efforts
to cause each person who is an affiliate of Titan, for purposes of qualifying
the merger for pooling of interests accounting treatment, to deliver to AverStar
no later than 31 days before the effective time of the merger a written
agreement intended to preserve the ability to treat the merger as a pooling of
interests and to ensure compliance with the Securities Act. AverStar has agreed
to the same undertaking with respect to its affiliates.

    This proxy statement/prospectus does not cover any resales of Titan common
stock, including Titan common stock issuable upon the exercise of any assumed
options, to be received by AverStar stockholders upon completion of the merger.
No person is authorized to make use of this proxy statement/prospectus in
connection with any resale.

ANTI-DILUTION ADJUSTMENTS

    If between March 24, 2000 and the effective time of the merger, the
outstanding shares of Titan common stock or AverStar common stock are changed
into a different number of shares because of any reclassification,
recapitalization, split-up, combination or exchange of shares, or if any
dividend payable in stock or other securities is declared on such shares with a
record date within this period, the merger agreement requires that the exchange
ratio be adjusted accordingly to provide the same economic effect as
contemplated by the merger agreement before such reclassification,
recapitalization, split-up, combination, exchange or dividend.

EXCHANGE OF CERTIFICATES

    Titan has agreed to deposit certificates representing the shares of Titan
common stock to be issued or paid under the merger agreement with an agent
designated by Titan and reasonably acceptable to AverStar, which will act as
exchange agent in the merger for the benefit of the holders of issued and
outstanding shares of AverStar common stock. Titan will cause the exchange agent
to mail a letter of transmittal to each holder of AverStar common stock. The
letter of transmittal will contain instructions on how AverStar stockholders may
surrender their AverStar stock certificates to the exchange agent in exchange
for Titan certificates.

                                       37
<PAGE>
    YOU SHOULD NOT RETURN YOUR STOCK CERTIFICATES WITH THE ENCLOSED PROXY, AND
YOU SHOULD NOT FORWARD THEM TO THE EXCHANGE AGENT UNTIL YOU RECEIVE THE LETTER
OF TRANSMITTAL. FOLLOWING YOUR RECEIPT OF THE LETTER OF TRANSMITTAL, YOU SHOULD
FORWARD THE CERTIFICATES ONLY IN ACCORDANCE WITH THE INSTRUCTIONS SPECIFIED IN
THE LETTER.

    After the effective time of the merger and until AverStar stockholders
surrender the certificates representing their AverStar common stock for
exchange, holders of these certificates will not be paid any dividends or other
distributions declared after the effective time of the merger on the Titan
common stock issuable to such stockholders in the merger. Any such unpaid
dividends or other distributions on such Titan common stock will be paid,
without interest, only to the holders who have properly tendered their AverStar
common stock certificates for exchange. All stock certificates presented after
the effective time of the merger will be canceled and exchanged for a
certificate or certificates representing the applicable number of shares of
Titan common stock to be received in the merger.

    Any shares of Titan common stock that remain undistributed 12 months after
the effective time of the merger will be delivered to Titan on demand. After
that time, certificates representing AverStar common stock must be surrendered
for exchange to Titan or to AverStar as the surviving corporation of the merger.
Titan and AverStar, as the surviving corporation of the merger, will not be
liable for any shares of Titan common stock or cash delivered to a public
official under any abandoned property, escheat or similar laws.

    If a certificate representing AverStar common stock has been lost, stolen or
destroyed, the exchange agent will issue the consideration payable under the
merger agreement when the claimant submits an affidavit of loss, theft or
destruction, and, if required by Titan in the case of any certificate
representing more than 7,500 shares of AverStar common stock, posts a bond as
indemnity against any claim that may be made later with respect to the lost
certificate.

             TERMS OF THE MERGER AGREEMENT AND RELATED TRANSACTIONS

    The following summary of the material terms and provisions of the merger
agreement is qualified in its entirety by reference to the merger agreement. The
merger agreement is attached as Appendix A to this proxy statement/prospectus
and is considered a part of this document.

GENERAL

    The merger agreement provides that at the effective time of the merger, V T
Acquisition Corp., a wholly owned subsidiary of Titan, will merge with and into
AverStar. AverStar will be the surviving corporation of the merger and will be a
wholly owned subsidiary of Titan. The separate corporate existence of V T
Acquisition Corp. will terminate at the effective time of the merger. At the
effective time of the merger, each AverStar stockholder will obtain the right to
receive, in exchange for each share of AverStar common stock held, the number of
shares of Titan common stock calculated as described below under "Conversion of
AverStar Common Stock."

    CERTIFICATE OF INCORPORATION AND BYLAWS OF THE SURVIVING CORPORATION.  The
certificate of incorporation of V T Acquisition Corp., as amended by the
certificate of merger, will become the certificate of incorporation of AverStar
after the merger. The bylaws of V T Acquisition Corp. will become the bylaws of
AverStar after the merger.

    DIRECTORS AND OFFICERS OF THE AVERSTAR AFTER THE MERGER.  The directors and
officers of V T Acquisition Corp. will be the initial directors and officers of
AverStar as the surviving corporation of the merger, and will serve until their
successors have been duly elected or appointed and qualified, or until their
earlier death, resignation or removal.

    DIRECTORS AND OFFICERS OF TITAN AFTER THE MERGER.  The merger agreement
provides that Michael B. Alexander, who currently is the Chairman and Chief
Executive Officer of AverStar, will become a director of Titan after the merger.
The following sets forth biographical information concerning Mr. Alexander:

    Michael B. Alexander has served as AverStar's Chief Executive Officer and
Chairman from February 1998 to the present, and as Chief Executive Officer and
Chairman of Intermetrics from August 1995 to February 1998. From 1993 to
August 1995, Mr. Alexander was the principal of AFH Partners, which invests in
public and private computer software companies. From 1990 to 1993,
Mr. Alexander served as President and Chief Operating Officer of
Pinelands, Inc., a New York Stock Exchange company that was a spin-off from
MCA, Inc. From 1981 to 1990, Mr. Alexander worked for MCA/Universal in several
capacities, including as President and General Manager of WWOR-TV, Executive
Vice President of MCA Broadcasting and Vice President and Chief Financial
Officer of USA Network. Mr. Alexander is a member of the Board of Directors of
IES Holding, Inc. Mr. Alexander received an AB from Harvard College, cum laude,
an MA in Education from Ohio State and completed the course work for a doctorate
in education from the Harvard Graduate School of Education.

    CONVERSION OF AVERSTAR COMMON STOCK.  In connection with the merger, all
outstanding classes of AverStar's common stock will be automatically converted
into one class of AverStar common stock pursuant to AverStar's certificate of
incorporation, as amended and restated, filed on February 27, 1998, and
stockholders' agreement dated as of February 27, 1998. Each share of Class D
common stock, Class F common stock and Class G common stock will be converted
into one share of AverStar common stock.


    The conversion rate of Class A common stock, Class B common stock, Class C
common stock and Class E common stock will be based upon several variables,
including the date the merger is completed and the determination of "transaction
value' as defined in the merger agreement. The determination of


                                       39
<PAGE>

"transaction value' is based in part on the consideration payable to AverStar
upon exercise of certain outstanding options, AverStar's net debt, and payments
made to AverStar stockholders to redeem AverStar common stock. The conversion
rate among Class A, Class B, Class C and Class E also may vary based upon the
trading price of Titan's common stock. However, AverStar's management believes
any such variation of the conversion rate would be immaterial. The discussion of
the conversion rate below is qualified in its entirety by reference to
AverStar's certificate of incorporation and stockholders' agreement.


    For illustration purposes, the allocations described below are based on the
following assumptions:


    - The merger is completed on June 28, 2000;


    - The relevant option consideration is $3.725 million;


    - AverStar's net debt is $61 million;



    - No payments are made to redeem stock;



    - If the average Titan stock price is less than $39.60, Titan elected to
      exercise the exchange ratio to prevent AverStar's termination of the
      merger agreement; and



    - If the average Titan stock price is greater than $61.60, AverStar elected
      to exercise the exchange ratio to prevent Titan's termination of the
      merger agreement.


Although AverStar's management believes that these assumptions are reasonable,
the final conversion rate may vary.

    CLASS A COMMON STOCK

    AverStar's Class A common stock is subject to an allocation for the benefit
of AverStar's Class E common stock. This allocation represents a percentage of
the increased value of AverStar Class A common stock from the date of the
acquisition of Intermetrics, as well as an interest factor.


    Based on the assumptions described above, upon the completion of the merger
and all required allocations, each share of Class A common stock will be
converted into approximately 0.96 shares of AverStar common stock.


    CLASS B COMMON STOCK

    AverStar's Class B common stock is subject to an allocation for the benefit
of AverStar's Class C common stock. This allocation represents a percentage of
the return on the original investment in Class B common stock in the acquisition
of Intermetrics.


    Based on the assumptions described above, upon the completion of the merger
and all required allocations, each share of Class B common stock will be
converted into approximately 0.82 shares of AverStar common stock.


    CLASS C COMMON STOCK

    AverStar's Class C common stock is entitled to the benefit of an allocation
from AverStar's Class B common stock. This allocation represents a percentage of
the return on the original investment in Class B common stock in the acquisition
of Intermetrics.


    Based on the assumptions described above, upon the completion of the merger
and all required allocations, each share of Class C common stock will be
converted into approximately 3.16 shares of AverStar common stock.


                                       40
<PAGE>
    CLASS E COMMON STOCK

    AverStar's Class E common stock is entitled to the benefit of an allocation
from AverStar's Class A common stock, including shares of AverStar's Class A
common stock held in treasury. This allocation represents a percentage of the
increased value of AverStar Class A common stock from the date of the
acquisition of Intermetrics, as well as an interest factor.


    Based on the assumptions described above, upon the completion of the merger
and all required allocations, each share of Class E common stock will be
converted into approximately 1.96 shares of AverStar common stock.


    CONVERSION OF AVERSTAR COMMON STOCK TO TITAN COMMON STOCK.  At the effective
time of the merger, after the conversion of all outstanding classes of AverStar
common stock into one class of AverStar common stock as explained above, each
issued and outstanding share of AverStar common stock will be converted into the
right to receive the number of shares of Titan common stock calculated as
described below. Fractional shares of Titan common stock will not be issued in
the merger, but instead will be rounded up to the nearest whole share of Titan
common stock.

    The number of shares of Titan common stock you will be entitled to receive
will depend on the merger exchange ratio of Titan common stock to AverStar
common stock. For example, if the merger exchange ratio is fixed at .35, you
would receive .35 of a share of Titan common stock for each AverStar share you
own. The merger exchange ratio has not been fixed in the merger agreement, but
will be calculated at the time of the merger in accordance with a formula
contained in the merger agreement. Under this formula, the merger exchange ratio
will be based on the average of the closing sale prices of the Titan common
stock on the NYSE for the ten consecutive trading days ending two trading days
immediately before the merger closing date. References to the average Titan
stock price in the following discussion mean the average of these closing sale
prices over the ten-day period.

    - If the average Titan stock price is less than $39.60, (a) AverStar has the
      right to terminate the merger agreement, unless Titan elects to have the
      exchange ratio fixed at an amount equal to the quotient obtained by
      dividing the product of the "AverStar stock value" (as defined below)
      multiplied by 0.90 by the average Titan stock price or (b) if AverStar
      does not exercise this termination right and Titan does not make the
      election described in (a), the exchange ratio will be equal to the
      quotient obtained by dividing the AverStar stock value by $44.00.

    - If the average Titan stock price is greater than or equal to $39.60 and
      less than $44.00, the exchange ratio will be equal to the quotient
      obtained by dividing the AverStar stock value by $44.00.

    - If the average Titan stock price is greater than or equal to $44.00 and
      less than or equal to $56.00, the exchange ratio will be equal to the
      quotient obtained by dividing the AverStar stock value by the average
      Titan stock price.

    - If the average Titan stock price is greater than $56.00 and less than or
      equal to $61.60, the exchange ratio will be equal to the quotient obtained
      by dividing the AverStar stock value by $56.00.

    - If the average Titan stock price is greater than $61.60, (a) Titan has the
      right to terminate the merger agreement unless AverStar elects to have the
      exchange ratio fixed at an amount equal to the quotient obtained by
      dividing the product of the AverStar stock value multiplied by 1.10 by the
      average Titan stock price or (b) if Titan does not exercise this
      termination right and AverStar does not make the election described in
      (a), the exchange ratio will be equal to the quotient obtained by dividing
      the AverStar stock value by $56.00.

    exchange ratio to prevent AverStar's termination of the merger agreement.

(2) This merger exchange ratio assumes AverStar elected to exercise its right to
    accept this merger exchange ratio to prevent Titan's termination of the
    merger agreement.

    Each share of AverStar common stock held in the treasury of AverStar after
all required allocations will be canceled at the effective time of the merger
without the payment of any consideration. Each share of common stock of V T
Acquisition Corp. issued and outstanding immediately before the effective time
of the merger will be converted into and exchanged for one share of common stock
of the surviving corporation of the merger, which will continue to be held by
Titan.


    ASSUMPTION OF OPTIONS.  As of May 19, 2000, AverStar's employees and others
had outstanding options to purchase 1,386,105 shares of AverStar common stock.
At the effective time of the merger, Titan will assume all outstanding AverStar
stock options. Each assumed option will be converted in the merger into an
option to purchase shares of Titan common stock using the same merger exchange
ratio. Except for the number of shares issuable upon exercise of such options
and the option exercise prices, which will be adjusted based on the merger
exchange ratio, the assumed options will remain subject to the same terms and
conditions that were in effect before the merger. The exercise price per share
of Titan common stock issuable under the assumed options will equal the exercise
price per share of AverStar common stock issuable under the applicable option at
the effective time of the merger divided by the exchange ratio, rounded to the
nearest whole cent.


    ESCROW.  Under the merger agreement, Titan, the surviving corporation after
the merger and their respective officers and directors, and each person who
controls or may control Titan or the surviving corporation within the meaning of
the Securities Act will be indemnified against losses and expenses incurred as a
result of:

    - any inaccuracy or breach of a representation or warranty of AverStar given
      or made by AverStar in the merger agreement or in any certificate,
      document or agreement delivered by AverStar pursuant to the merger
      agreement, including the certificate of merger; and

    - any failure of AverStar to perform or comply with any covenant or
      agreement contained in the merger agreement or in any other certificate,
      document or agreement delivered by AverStar pursuant to the merger
      agreement.

    Titan and its affiliates will be indemnified from an escrow fund. In
addition, any difference between AverStar's estimated net debt as set forth in
the certificate that AverStar is required to deliver to Titan two days prior to
the closing date of the merger and the actual net debt as of the closing date of
the merger will be paid to Titan from the escrow fund. The escrow fund will be
governed by an escrow agreement and First Union National Bank will act as escrow
agent. The escrow agreement is attached to this proxy statement/prospectus
substantially in the form of Appendix B. On the earlier of five business days
after the final determination of any adjustment or 90 days after the closing of
the merger, the shares of Titan common stock held in escrow, other than any
amounts taken out to pay any closing or loss adjustment or any amounts that are
pending final resolution of any disputes therefrom, will be released to the
former holders of AverStar common stock (other than those who exercised
appraisal rights) pro-rata in accordance with the number of shares of Titan
common stock held by each former AverStar stockholder immediately after the
effective time of the merger.

    Upon the surrender of a properly executed certificate representing shares of
AverStar common stock to the exchange agent, a number of shares of Titan common
stock equal to 5% of the transaction value divided by the average of the closing
sale prices of Titan common stock on the New York Stock Exchange for the ten
consecutive trading days ending two trading days immediately before the merger
closing date will be delivered to the escrow agent and will comprise the escrow
fund. All dividends or

                                       44
<PAGE>
distributions (other than stock or similar dividends) will be distributed to
stockholders whose shares are held in the escrow fund by the escrow agent in
accordance with the escrow agreement.

EFFECTIVE TIME

    The merger will occur as soon as practicable after the satisfaction or
waiver of all of the conditions precedent set forth in the merger agreement. The
effective time of the merger will be the date and time that Titan and AverStar
file a certificate of merger with the Delaware secretary of state. If the merger
is not completed by September 20, 2000, which date may be extended by mutual
consent of Titan and AverStar, the merger agreement may be terminated by either
Titan or AverStar, unless the failure to consummate the merger by this date is
due to the material failure of the party seeking to terminate the merger
agreement to fulfill any of its obligations.

      law;

    - before furnishing information to, or entering into discussions or
      negotiations with, the person or entity, AverStar provides written notice

AVERSTAR VOTING AGREEMENT

    AVERSTAR VOTING AGREEMENT.  On March 24, 2000, as an essential condition and
inducement to Titan and V T Acquisition Corp. entering into the merger
agreement, Titan, V T Acquisition Corp. and several AverStar stockholders,
referred to as the AverStar Principal Stockholders, entered into a Voting
Agreement. Under the Voting Agreement, the AverStar Principal Stockholders have
agreed to vote, or cause the record holders of their AverStar securities to
vote, the AverStar common stock beneficially owned by them as of March 24, 2000
and any other voting interests in AverStar acquired by them after March 24, 2000
in the following manner:

    - in favor of the merger and adoption of the merger agreement;

    - in favor of other actions contemplated by the merger agreement in
      connection with any meeting of, or solicitation of consents from, AverStar
      stockholders where such matters are submitted to a vote of AverStar
      stockholders;

    - against approval or adoption of any extraordinary transaction (other than
      the merger) including, without limitation, the sale or transfer of all or
      substantially all of AverStar's capital stock or assets, a reorganization
      or liquidation or AverStar or the creation of a new class of AverStar
      securities;

    - against approval or adoption of resolutions which would have the effect of
      preventing or materially delaying completion of the merger or AverStar
      from performing its obligations under the merger agreement; and

    - against any other action which would constitute a material breach of any
      provision of the merger agreement.


    The AverStar common stock beneficially owned by the AverStar Principal
Stockholders represented approximately 31.3% of the AverStar voting common stock
outstanding as of May 19, 2000. The AverStar Principal Stockholders consist of
the following persons:


    - Michael B. Alexander, AverStar's Chairman and Chief Executive Officer of
      AverStar;

                                       57
<PAGE>
    - AFH Partners, L.P.;

    - Peter J. Dwyer, AverStar's Chief Financial Officer;

    - Nicholas A. Pettinella;

    - John C. Rennie, AverStar's Vice Chairman;

    - Sigmund H. Goldblum, AverStar's President of Applications Group;

    - Joseph A. Saponaro, AverStar's President and Chief Operating Officer;

    - Peter M. Shulte;

    - Levy Family Partnership; and

    - Bruce A. Burton

    Under the Voting Agreement, each AverStar Principal Stockholder delivered an
irrevocable proxy to Titan to vote the AverStar shares of such AverStar
Principal Stockholder in favor of the merger, as described under "Irrevocable
Proxies" below.

    The AverStar Principal Stockholders have agreed not to take any of the
following actions until the effective time of the merger or, if earlier
terminated, the termination of the Voting Agreement, and to use their reasonable
efforts not to allow any of their representatives to take any of the following
actions:

    - initiate, solicit, facilitate or encourage the submission of an
      acquisition proposal for AverStar;

    - participate in any discussions with respect to an acquisition proposal for
      AverStar;

    - agree to, approve or recommend or authorize any representative of AverStar
      to approve or recommend any acquisition proposal for AverStar;

    - execute any proxies or other voting arrangements with respect to AverStar
      capital stock or rights to acquire AverStar capital stock; or

    - transfer or otherwise dispose of any shares of capital stock beneficially
      owned by the AverStar Principal Stockholders.

    The Voting Agreement will terminate on the earlier to occur of the effective
time of the merger or on the date the merger agreement is validly terminated.

    IRREVOCABLE PROXIES.  Under the Voting Agreement, and as a condition and
inducement to Titan's entering into the merger agreement, each AverStar
Principal Stockholder granted an irrevocable proxy dated March 24, 2000 to
Titan, with power of substitution and resubstitution. Under the terms of each
proxy, Titan has the authority to vote the AverStar common stock owned by the
applicable AverStar Principal Stockholder as of March 24, 2000, together with
all other shares of AverStar capital stock the AverStar Principal Stockholder
acquires after March 24, 2000, in favor of the approval and adoption of the
merger agreement and the transactions contemplated by the merger agreement. Each
proxy authorizes Titan to vote these shares at any meeting of stockholders of
AverStar, or in connection with any solicitation of written consents from
stockholders of AverStar, called or solicited for the purpose of voting on the
merger agreement, the merger and the other actions contemplated by the merger
agreement. Each proxy is coupled with an interest and is irrevocable. The proxy
and the rights contained in it will terminate upon the termination of the Voting
Agreement.

                    THE TITAN CORPORATION AND AVERSTAR, INC.
             UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL DATA


    We expect that the merger of Titan and AverStar will be accounted for under
the pooling of interests method of accounting, which means that, for accounting
and financial reporting purposes, Titan and AverStar will be treated as if they
had always been combined. We have presented below unaudited pro forma condensed
combined financial data that reflect the pooling of interests method of
accounting and are intended to give you a better picture of what the businesses
of Titan and AverStar might have looked like if the merger between the two
companies had occurred on January 1, 1997, the first day of the first period for
which financial information is presented here. We have combined the Titan
unaudited pro forma condensed statement of operations data for the years ended
December 31, 1997, 1998 and 1999 and for the three months ended March 31, 2000
with the AverStar consolidated statements of operations for the years ended
December 31, 1997, 1998 and 1999 and for the three months ended March 31, 2000
to reflect the proposed merger of Titan and AverStar. Titan and AverStar might
have performed differently if they had been combined.



    The unaudited pro forma condensed combined statement of operations data for
Titan for the year ended December 31, 1999 assumes that Titan completed the
acquisitions of JB Systems, Inc., doing business as Mainsaver, Assist
Cornerstone Technologies, Inc. ("Assist") and SFG Technologies, Inc. ("SFG") as
of the beginning of such period. The unaudited pro forma condensed combined
financial data presented below have been derived from, and should be read in
conjunction with, the "The Titan Corporation Unaudited Pro Forma Condensed
Combined Financial Information" and related notes herein and the financial
statements of Mainsaver, Assist and SFG incorporated by reference herein. You
should not rely on the unaudited pro forma condensed combined financial data as
being indicative of the results that would have occurred or of the future
results that will occur after the merger.



    Unaudited condensed combined balance sheets have been prepared as of
December 31, 1999 and March 31, 2000 giving effect to the merger with AverStar
as though it had been consummated on those dates.

                    THE TITAN CORPORATION AND AVERSTAR, INC.

      NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

NOTE 1.  BASIS OF PRESENTATION


    The unaudited pro forma condensed combined statements of operations combine
the unaudited pro forma condensed combined statements of operations for Titan
for the years ended December 31, 1999, 1998 and 1997 and the three months ended
March 31, 2000 with the historical statements of operations of AverStar for the
years ended December 31, 1999, 1998 and 1997 and the three months ended
March 31, 2000.


NOTE 2.  BALANCE SHEET

    (a) Titan estimates that Titan and AverStar will incur direct transaction
costs and employee termination costs of approximately $11.6 million associated
with the Merger, the direct transaction costs consisting primarily of investment
banking, filings with regulatory agencies, accounting, legal, financial printing
and other related costs.


    These estimates are preliminary and are therefore subject to change. These
costs will be charged to operations as incurred. The unaudited pro forma
combined balance sheets give effect to such charges as if they had been incurred
as of December 31, 1999 and as of March 31, 2000, but the effect has not been
reflected in the unaudited pro forma condensed combined statements of operations
as they are nonrecurring in nature.


    The income tax effect of these charges has also been reflected as a pro
forma adjustment.


    (b) Titan has eliminated AverStar's treasury stock and reflected the
estimated impact to common stock and capital in excess of par value for the
estimated Titan shares to be issued.


NOTE 3.  STATEMENTS OF OPERATIONS


    (c) Titan bases the unaudited pro forma combined net income (loss) from
continuing operations per common share on the weighted average number of common
and equivalent shares of Titan outstanding for each period with an assumed
3,863,000 Titan shares issued for shares of AverStar common stock issued and
stock options issued and outstanding. The exchange assumes the sum of
transaction value of $205 million plus approximately $3.7 million, which is the
sum of the exercise of all vested AverStar options issued and outstanding less
one-half of the exercise of all unvested AverStar options issued and
outstanding, less estimated net debt of approximately $61 million the sum of
which is multiplied by .90, then divided by an assumed Titan average stock price
of $34.39 per share, the trailing ten-day average assuming a close date of
May 19, 2000. The assumed Titan shares to be issued equals an approximate .5150
exchange ratio (calculated as the quotient of the 3,863,000 Titan shares to be
issued divided by the total diluted outstanding AverStar shares of 7,500,000 as
of December 31, 1999) per AverStar share outstanding as of December 31, 1999.
The estimated exchange ratio calculated using the total AverStar outstanding
shares and options as of May 19, 2000 of 8,214,000, assuming 3,863,000 of Titan
shares issued is approximately .470195.


    The effect of the estimated direct transaction costs are not reflected in
the pro forma condensed combined statements of operations included herein. These
costs will be charged to operations in the period in which they are incurred,
which is estimated to be in the quarter ended June 30, 2000.

          UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION


    The accompanying unaudited pro forma condensed combined financial statements
should be read in conjunction with the notes to consolidated financial
statements contained in Titan's Annual Report on Form 10-K/A for the year ended
December 31, 1999, the notes to the financial statements of JB Systems, Inc.
(d.b.a. "Mainsaver"), Assist Cornerstone Technologies, Inc. ("Assist") and SFG
Technologies, Inc. ("SFG Technologies") incorporated by reference herein.
Mainsaver, Assist and SFG Technologies are collectively referred to hereinafter
as the "acquired companies."



    The following unaudited pro forma condensed combined statements of
operations have been prepared to illustrate the estimated effects of the
acquisitions of the acquired companies, for the year ended December 31, 1999.
The operating results of Mainsaver, Assist and SFG Technologies from their
respective dates of acquisition through December 31, 1999 are included in
Titan's operating results for the year ended December 31, 1999. The unaudited
pro forma condensed combined statements of operations for 1999 combine Titan's
revenues and expenses for the year ended December 31, 1999 with the acquired
companies' revenues and expenses from January 1, 1999 through their respective
dates of acquisition in November and December 1999.



    The unaudited pro forma adjustments are based upon available information and
upon certain assumptions that management believes are reasonable in the
circumstances. The unaudited pro forma condensed combined statements of
operations include the recurring items which are directly attributable to
acquisitions, such as amortization of additional goodwill, increase in interest
expense and the related tax effects thereof. The unaudited pro forma condensed
combined statements of operations give effect to the acquisitions of the
acquired companies as if they had occurred on January 1, 1999. The unaudited pro
forma condensed combined statements do not purport to represent what Titan's
financial position or results of operations would actually have been if the
acquisitions in fact had occurred on the date or at the beginning of the periods
indicated, nor do they purport to project our financial position or results of
operations for any future date or period.

           NOTES TO PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

                                  (UNAUDITED)

1. GENERAL


    Cayenta, Inc. ("Cayenta"), a majority owned subsidiary of The Titan
Corporation ("Titan"), acquired substantially all of the assets and liabilities
of Transnational Partners in January 1999. Thereafter, Cayenta acquired
Mainsaver in November 1999, and Assist and SFG Technologies in December 1999.
(See Note 3--The Acquired Companies).


2. BASIS OF PRESENTATION


    The accompanying unaudited pro forma condensed combined financial statements
are based on adjustments to Titan's historical consolidated financial statements
to give effect to the acquisitions described in Note 3 below. The pro forma
combined statements of operations assume the acquisitions were consummated as of
the beginning of the periods presented. The pro forma combined statements of
operations are not necessarily indicative of results that would have occurred if
the acquisitions had been consummated as of the beginning of the periods
presented or the results that may be attained in the future.



    Certain information normally included in financial statements prepared in
accordance with generally accepted accounting principles has been condensed or
omitted pursuant to the rules and regulations of the SEC. The pro forma combined
financial statements should be read in conjunction with the historical
consolidated financial statements of Titan and the historical financial
statements of the acquired companies.



    The information in the unaudited pro forma combined statements of operations
for the year ended December 31, 1999 was derived from (i) the audited statements
of operations of Titan, and each of the acquired companies for the year ended
December 31, 1999, and Mainsaver, Assist and SFG Technologies from January 1,
1999 through the respective dates of acquisition in November and December 1999.


    The financial statements of SFG Technologies are translated from Canadian
dollars to U.S. dollars based on the end of the period exchange rate for balance
sheet items and average for the period rates for statement of operations data.
There are no significant differences between U.S. and Canadian generally
accepted accounting principles relative to SFG Technologies.

3. ACQUISITIONS

    All acquisitions were accounted for as purchases. Accordingly the operating
results are reflected in the consolidated results of Cayenta from the date of
acquisition. Summary information on the acquisitions follows:

THE ACQUIRED COMPANIES


    TRANSNATIONAL PARTNERS.  In January 1999, Cayenta acquired substantially all
of the assets of Transnational Partners, an enterprise application integration
consulting company. Cayenta acquired these assets for an initial installment of
$7 million in cash and 2,345,000 shares of Cayenta's convertible stock. Cayenta
paid an additional $2.8 million note that was issued as part of its acquisition
of Transnational Partners, plus 7% interest thereon, in February 2000.

                                  (UNAUDITED)

3. ACQUISITIONS (CONTINUED)
    MAINSAVER.  In November 1999, Cayenta acquired Mainsaver, an enterprise
asset management company. Cayenta acquired Mainsaver for $11.7 million in cash,
of which $8.2 million was paid at the closing. Of the $3.5 million withheld at
the closing, $500,000 was due in March 2000 and $3.0 million is due in May 2001,
after satisfaction of possible working capital adjustments or indemnification
obligations. In addition, Cayenta paid approximately $3.4 million to reduce
outstanding indebtedness of Mainsaver.


    ASSIST CORNERSTONE.  In December 1999, Cayenta acquired Assist, an
e-commerce solutions and software company. Cayenta acquired Assist for 516,458
shares of its Class A common stock and approximately $12.9 million in cash, of
which $9.9 million was paid at the closing. Of the $3.0 million withheld at the
closing, $1.7 million was due and paid in March 2000 and $1.3 million is due in
June 2001, after satisfaction of possible working capital adjustments or
indemnification obligations. In addition, Cayenta paid approximately
$3.2 million to retire outstanding indebtedness of Assist and redeem all of its
outstanding redeemable preferred stock.


    SFG TECHNOLOGIES.  In December 1999, Cayenta acquired SFG Technologies, a
solutions and software provider focusing on revenue cycle services for the
utility industry. Cayenta acquired SFG Technologies for $11.6 million in cash,
less a $2.0 million holdback. Of the $2.0 million holdback placed into escrow at
the closing, approximately $0.4 million was paid in March 2000, $0.1 million was
offset against post closing adjustments in March 2000 and $1.5 million is due in
June 2001, after satisfaction of certain working capital adjustments or
indemnification obligations. In addition, Cayenta paid approximately
$3.1 million to retire outstanding indebtedness of SFG Technologies.


    Acquisition costs related to the acquired companies approximated $5.1
million, which includes approximately $2.1 million of estimated fair value
assigned to 495,800 warrants granted to an investment advisor for certain
advisory services performed in connection with these acquisitions. Goodwill
related to these acquisitions amounted to approximately $55.8 million and is
being amortized over their estimated useful lives.


4. ADJUSTMENTS TO HISTORICAL FINANCIAL STATEMENTS


    The following pro forma adjustments have been made to the historical
condensed consolidated statements of operations as if the acquisitions of the
acquired companies were consummated at January 1, 1999



    STATEMENTS OF OPERATIONS


    Acquisitions:


        (b) To reflect incremental amortization of goodwill related to the
    purchase of Mainsaver, Assist and SFG Technologies.

                            INFORMATION ABOUT TITAN

GENERAL


    Titan is a leading diversified technology company that provides information
technology, communications, and electron beam food pasteurization and medical
product sterilization systems and services. Through extensive government-funded
contract and research and development activities since 1981 under contracts
totaling in excess of $2 billion, Titan has accumulated a broad portfolio of
technologies, intellectual property and expertise from which Titan has developed
many of its commercial businesses. The core technologies supporting the SureBeam
and Titan Wireless segments were derived from technologies originally developed
for government applications. Titan believes that its government-funded contract
and research and development activities enhance its technical expertise with
sophisticated technologies and facilitate its ability to develop commercial
applications. Titan funds the development of commercial technologies from its
technology base both internally as well as in conjunction with partners. In
1997, for example, Titan contributed the core technology to form IPivot, Inc., a
company which designs and manufactures Internet commerce equipment that improves
the performance of server farms, web sites and software applications. In
November 1999, Titan received approximately $42 million in cash for its 8.1%
equity interest when IPivot was acquired by Intel Corporation. Titan plans to
continue building its technology portfolio, identifying commercial applications
and entering into strategic relationships to further its growth.


    Titan has organized its business into five segments that reflect the
specific markets and industries in which Titan operates:

experience in the segment's particular business and market area. Consistent with
its strategy of aligning management motivation with stockholder interests, each
of Titan's segments other than Emerging Technologies, which is not a separate
subsidiary, has its own key employee stock option plan to foster an
entrepreneurial environment.

Titan Systems................   The U.S. government is among the largest
                                buyers of information technology systems and
                                services in the world. According to the

                                2003. In addition, International Data
                                Corporation estimates that the worldwide
                                market for consulting, design, systems
                                integration, support, management and

                                $7.8 billion 1998 to $78.5 billion in 2003.

SureBeam.....................   With 75.4 billion pounds of meat, including
                                beef, pork and poultry, produced in the
                                United States in 1999, SureBeam estimates
                                that the market for food pasteurization
                                systems and services could develop to be in
                                excess of $3.0 billion annually if irradiated
                                foods gain consumer acceptance. If such
                                consumer acceptance occurs, SureBeam believes
                                that meat producers will initially elect to
                                pasteurize a portion of their ground beef and
                                poultry production. According to a market
                                research report, the global market for
                                sterilization services for medical products
                                was approximately $368 million in 1999.

Titan Wireless...............   In Titan's targeted markets, telephone
                                availability is relatively low. In 1998,
                                according to the International
                                Telecommunication Union, countries in Titan's
                                targeted markets, which represent

                                population, had fewer than two subscriber

                           INFORMATION ABOUT AVERSTAR

GENERAL

    AverStar provides information technology, or IT, services and software
products for the mission-critical systems of a significant number of civilian
and defense agencies of the United States government.

    AverStar provides an integrated offering of services and products in three
areas of IT:

    - IT ASSURANCE. AverStar provides independent analysis, testing and
      verification of critical information systems under development or being
      upgraded. AverStar also provides security for customers' information
      systems.

    - IT DEVELOPMENT. AverStar offers a full range of software and systems
      development services for customer-specific applications and Internet
      applications.

    - IT OPERATIONS. AverStar manages and operates information system networks

    AverStar provides IT assurance services for many of the United States
government's mission-critical systems. Our key IT assurance contracts include
NASA's space shuttle, space station and ground systems, the Health Care Finance
Administration's Medicare transactions system and the United States Postal
Service's automation systems.


    AverStar's current business and operations result from a series of strategic
acquisitions of well established IT companies, executed by its current
management team. In February 1998, AverStar was formed to combine the businesses
of Intermetrics, Inc. and Pacer Infotec, Inc. Previously, Pacer acquired Infotec
Development, Inc. in July 1996. Founded in 1969, Intermetrics brought AverStar
expertise in IT assurance and IT development services for United States civilian
and defense agencies and for commercial organizations. Founded in 1968, Pacer
broadened AverStar's base of contracts for IT assurance and IT development
services for United States defense and civilian agencies. In March 1999,
AverStar acquired Computer Based Systems, Inc. Founded in 1978, CBSI
strengthened AverStar's IT operations services and broadened AverStar's customer
base among civilian agencies of the federal government. In March 2000, AverStar
acquired MJR for $9.6 million in cash, plus a maximum contingent future
consideration of $3.75 million based on MJR's year 2000 financial results. MJR
is an IT service company supporting New York city area clients, primarily in the
financial services industry.


AVERSTAR'S SERVICES AND PRODUCTS

    AverStar provides its customers with an integrated offering of services and
products in three areas: IT assurance, IT development and IT operations. Through
these offerings, AverStar is able to support customers during all or any
particular phase of the life cycle of an information system.

IT ASSURANCE

    AverStar's IT assurance services include the independent analysis, review,
testing, verification and validation of information systems under development or
being upgraded. Customers increasingly view more of their information systems as
being critical to their operations. This growth in the number of critical
systems, which must operate correctly and be delivered within schedule and cost
constraints, has increased the market demand for our IT assurance services.

    AverStar provides the following types of IT assurance services:

    SYSTEMS ASSURANCE.  AverStar's systems assurance services involve
independent assessment of the specification, design, implementation and testing
of information systems being developed for our

                                       75
<PAGE>
customers. AverStar focuses on early detection of problems so that
cost-effective corrections can be made early in the development cycle. AverStar
also evaluates the processes and tools being used by the systems developer and
provide oversight in tracking the customer's schedule and budget. AverStar's
systems assurance methodologies, tools and services verify its customers'
information systems and provide them with comprehensive technical reports
detailing any and all tracking and reporting problems.

    INFORMATION ASSURANCE.  AverStar's information assurance services include
providing customers with security risk assessments, security policy and
architecture design, and certification and accreditation of IT systems.
AverStar's solutions help customers automate highly secure transmissions of data
across communications networks. With more information systems migrating to
Internet and Intranet applications, the potential threat from computer viruses
and computer hackers increases the demand for these services. AverStar also
offers products that provide customers with the ability to control a user's
access to network systems in a multi-level, secure environment.

    COMPLIANCE ASSESSMENTS.  Customers retain AverStar to determine whether a
specific component of an information system complies with their specifications.
The scope of AverStar's compliance assessment services may vary from assessing
the readiness of software for operational implementation, to assessing the
process, cost and schedule for an information system upgrade.

IT DEVELOPMENT

    AverStar's IT development services include specification and design, coding
and implementation, system integration, testing and verification, training and
operational deployment of IT systems. AverStar uses both its proprietary and
commercially available tools, together with well established procedures, to
develop and implement IT systems. AverStar's many years of experience in
performing IT assurance services on major systems provide it with a competitive
advantage as an IT developer through the use of processes that avoid common
development problems and through the utilization of project management
disciplines to control the cost, schedule and performance of our projects.
AverStar's IT development services specialize in the following:

    MISSION APPLICATIONS.  Mission applications involve developing and
maintaining software and systems to support customer-specific programs or
operations.

    ELECTRONIC BUSINESS.  Applications for electronic business involve enabling
legacy systems for web-based access and building new Internet and intranet
applications for government and commercial customers.

IT OPERATIONS

    AverStar's IT operations include network and desktop operations and complete
data center operations at its customers' facilities. AverStar installs,
maintains and supports its customers' network and desktop operations. AverStar's
data center operations include software development, data collection and input,
database archives, report generation and hardware maintenance. AverStar also
supports customers in incorporating new technologies and requirements into their
operations. As a provider of end-to-end services for these operations, AverStar
frequently calls upon its expertise in IT assurance and IT development to
fulfill particular requirements of an IT operations contract.

    AverStar recently expanded its IT operations services through the
acquisition of CBSI, a company that has significant expertise in providing IT
operations services to several civilian agencies of the federal government.

AVERSTAR'S MARKETS AND CUSTOMERS

    AverStar's primary customers are agencies of the United States government.
AverStar's ten largest contracts by revenues are all with United States
government agencies and accounted for approximately 49% of AverStar's 1999 pro
forma revenues. In 1999, the United States Navy accounted for approximately 12%
of AverStar's pro forma revenues and NASA accounted for approximately 12% of
AverStar's pro forma revenues. These revenues are the result of various
contracts awarded by several procurement offices within these agencies.
AverStar's experience has indicated that particular contracts are subject to the
discretion of each procurement office. Of the 20 government agencies with the
largest IT budgets for the government's 1999 fiscal year, AverStar has contracts
with 16. The breadth of AverStar's government contract base and service
offerings provides it with less dependence on any one agency and more
opportunities to sell additional services to AverStar's customers.

CONTRACTS

GOVERNMENT CONTRACTS

    Typically, the government purchases AverStar's IT services and products
through one of the following contract vehicles: single-agency contracts,
multiple award contracts, government wide acquisition contracts, or GWACs, or
Government Services Agency Schedule contracts. A single agency contract is
awarded by one government agency to one or more IT service providers to perform
a specific task. Multiple award contracts, GWACs and Government Services Agency
Schedule contracts permit government agencies to purchase IT services and
products at pre-approved prices, terms and conditions without any additional
competitive bidding. Multiple award contracts and GWACs are awarded by one
government agency to several IT service providers. Government Services Agency
Schedule contracts are awarded by one government agency to one IT service
provider, covering multiple services and products. Even government agencies that
are not parties to the contract may purchase IT services and products through
any GWAC or Government Services Agency Schedule contract. The term of AverStar's
current Government Services Agency Schedule contract expires in September 2002.

    AverStar has several multi-year contracts with United States government
agencies, typically for three to five years. These contracts require AverStar to
provide a broad range of requested services. AverStar receives specific
assignments under a given contract through the issuance by the government of
task orders. Task orders describe the specific assignment, the number of
employees allocated to the assignment and the estimated cost, fee and travel
allocated to the assignment.

    AverStar serves as the prime contractor on a majority of AverStar's
contracts. Prime contracts accounted for approximately 76% of AverStar's 1999
pro forma revenues. AverStar believes that its position as prime contractor
allows it to develop closer relationships with its customers, to control the
quality of services and products delivered to the customer and to expand its
customer relationships.

COMMERCIAL CONTRACTS

    Typically, commercial contracts require AverStar to complete a specific task
or provide a defined range of services and support. Payments are usually made
incrementally during the performance of each specific work assignment.
Currently, AverStar is working to expand its customer base and increase the
sales of AverStar's products and services in the commercial IT market. Most of
AverStar's existing commercial contracts are time and materials contracts.

BACKLOG

    Backlog represents AverStar's management's estimate of AverStar's aggregate
realizable revenues over the term of all of AverStar's contracts, including any
option periods. However, backlog is not

                                       77
<PAGE>
necessarily indicative of future revenues. AverStar's contract backlog was
approximately $350 million as of December 31, 1999. AverStar's backlog is
composed of:

    - Customer authorized contract values for which the customer has set aside,
      appropriated or committed funds for specifically identified services,
      products, tasks or delivery orders; and

    - AverStar's management's estimate, based on AverStar's past experience and
      long-term relationships with many of AverStar's customers, of the
      realizable contract values for all expected future services, products,
      tasks or delivery orders under AverStar's commercial contracts and single
      agency, Government Service Administration schedule, multiple award and
      government-wide acquisition contracts, for which funds have not yet been
      set aside, appropriated or committed, even if AverStar's customer is not
      obligated to request any services under a contract.

    The actual timing of AverStar's receipt of revenues, if any, on projects
included in its backlog could change because many factors affect the scheduling
of projects. In addition, cancellations or adjustments to contracts may occur.
AverStar's backlog is subject to large variations from quarter to quarter as
existing contracts are renewed or new contracts are awarded. Additionally,
virtually all of AverStar's backlog represents contracts with the United States
government which may be terminated at any time for any reason.

COMPETITION

    AverStar experiences significant competition in all areas of its business.
In general, the markets in which AverStar competes are not dominated by a single
company or a small number of companies. Rather, a large number of companies
offer services that overlap and are competitive with AverStar's services and
products. However, AverStar competes regularly with approximately seven
different competitors in its IT assurance service offerings, 18 in its IT
development service offerings and six in its IT operation service offerings.

    AverStar believes that the principal competitive factors in its business are
technical understanding, management capability, past contract performance,
personnel qualifications and price. While AverStar has considerable experience,
there are many other contractors that have comparable skills. Many of AverStar's
competitors are significantly larger and have greater financial resources than
AverStar does. In addition, many of AverStar's competitors have significantly
more experience in the commercial IT market than AverStar does.

PROPRIETARY INFORMATION

    Although much of AverStar's work is performed for the United States
government, wherever possible AverStar attempts to retain proprietary rights in
its products. AverStar relies on copyright, patent and trade secret laws and
internal non-disclosure safeguards, as well as restrictions incorporated into
software product license agreements and other contractual provisions to protect
its proprietary rights. However, AverStar does not have any patents, trademarks
or licenses that are material to its business. In addition, AverStar's efforts
to protect its proprietary rights may not prevent the unauthorized disclosure or
use of AverStar's technical knowledge, practices or procedures, or prevent
others from independently developing similar knowledge, practices or procedures.
Further, the government may acquire proprietary rights to software programs and
other products that AverStar develops while performing services under government
contracts. The government may disclose this information to others, including
AverStar's competitors. Disclosure or loss of control over AverStar's
proprietary information could have a material adverse effect on AverStar's
business, financial condition and results of operations.

EMPLOYEES

    As of December 31, 1999, AverStar had a total of 1,713 employees, consisting
of 1,557 full-time and 156 part-time or temporary employees. Of AverStar's total
full-time employees, approximately 1,420 are in engineering, technical and
technical support positions, 109 are in general and administrative positions and
28 are in sales and marketing positions. None of AverStar's employees are
covered by a collective bargaining agreement.

    AverStar has several full-time employees dedicated to recruiting technical
and administrative professionals and managing its human resources. As part of
AverStar's retention efforts, AverStar seeks to minimize turnover by emphasizing
its reputation, the nature of its work, its work environment, its encouragement
of technical publications, its participation in professional societies and its
competitive compensation packages.

REGULATORY MATTERS

    United States government contracts are subject to the Federal Acquisition
Regulations, or FAR, and other agency FAR supplements. Major United States
government contracts are also subject to the Truth in Negotiations Act, or TIN
Act, and Cost Accounting Standards, or CAS. Among other procurement regulations,
the FAR contains the cost principles for setting contract prices while the TIN
Act requires AverStar to provide current, accurate and complete cost or pricing
data in connection with the negotiation of a contract. CAS requires consistency
of accounting practices over time and compliance with specific cost accounting
criteria.

    To the extent that a company fails to comply with procurement requirements,
the United States government may adjust contract prices. Additionally, changes
in cost accounting practices are subject to a required procedure for negotiation
of the cost of the change. The United States government is protected from paying
increased costs resulting from accounting changes. Finally, the United States
government has the right to audit contractors for three years after final
payment. Accordingly, Averstar's revenues from United States government
contracts are subject to adjustment.

    United States law and regulations restrict and regulate the export of
technology as well as goods and commodities provided by United States businesses
to controlled foreign subsidiaries and affiliates. AverStar is subject to
regulations applicable to its technology that is sold to non-United States
customers.

LEGAL PROCEEDINGS

    AverStar is not involved in any material litigation.

AVERSTAR'S MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
  RESULTS OF OPERATIONS

    OVERVIEW.  AverStar provides IT services and products to the United States
government and to commercial companies. Through both internal growth and a
series of acquisitions, AverStar has increased its revenues from $53.3 million
for the fiscal period ended February 28, 1997 to $195 million in pro forma
revenues for the fiscal period ended December 31, 1999. AverStar's growth has
resulted in a broader base of long-term contracts and a more diverse group of
established customers.

    AverStar is the result of a series of strategic acquisitions executed by
AverStar's current management. In February 1998, AverStar combined the
businesses of Intermetrics and Pacer. In March 1999, AverStar acquired CBSI for
$26 million in cash, $25 million of which was paid to the former CBSI
stockholders at the closing and $1 million of which will be paid ratably over
the next five years. In March 2000, AverStar acquired MJR for $9.6 million in
cash, plus a maximum contingent future consideration of $3.75 million based on
MJR's year 2000 financial results. All three transactions were accounted for as
purchases. During 1997, AverStar changed its fiscal year to a
December 31 year-end in anticipation of the merger with Pacer. As a result, the
fiscal period ended December 31, 1997 is a ten-month period.

    A substantial portion of AverStar's revenues are derived from contracts with
the United States government. Approximately 91% of AverStar's pro forma revenues
in the fiscal period ended December 31, 1999, were derived from government
contracts, either directly with government customers or indirectly through
government prime contractors.

    AverStar enters into three types of contracts: cost-reimbursable,
time-and-materials and fixed-price contracts. Of AverStar's total pro forma
revenues for 1999, cost-reimbursable contracts represented approximately 41%,
time-and-materials contracts approximately 49% and fixed-price and licensing
contracts approximately 10%. Cost-reimbursable contracts provide for the
reimbursement of costs plus the payment of a fixed fee. Under time-and-materials
contracts, AverStar is reimbursed for labor hours at negotiated hourly billing
rates and reimbursed for travel and other direct expenses at actual cost plus
applied indirect, general and administrative expenses. Under fixed-price
contracts, AverStar agrees to perform an assignment for a fixed price and,
accordingly, realize a benefit or detriment to the extent that our actual cost
of performing the work differs from the negotiated price.

    AverStar assumes greater financial risk on fixed-price contracts than on
either time-and-materials or cost-reimbursable contracts. AverStar believes that
an increasing percentage of its contracts will be time and materials contracts
as its commercial business increases and as the government increases its
procurement under AverStar's GSA Schedule and GWAC's. Failure to anticipate
technical problems, estimate costs accurately or control costs during
performance of a fixed-price contract may reduce AverStar's profits or cause
AverStar to suffer a loss. If AverStar is successful in providing its services
at a reduced cost, however, AverStar expects that fixed-price contracts will
result in greater profitability. In addition, greater risks are involved under
time-and-materials contracts than under cost-reimbursement contracts because
AverStar assumes the responsibility for the delivery of specified skills at a
fixed hourly rate. AverStar's management believes that adequate reserves for its
fixed-price and time-and-materials contracts are reflected in its financial
statements.

    AverStar recognizes revenues on government and commercial contracts under
the percentage-of-completion method. This method involves a periodic assessment
of the estimated total cost to complete each contract. The
percentage-of-completion method is determined by relating the actual costs
incurred to date to the estimated total costs at completion. The cumulative
effects resulting from revisions of estimated total costs and revenues are
recorded in the period in which the facts requiring revisions become known. When
a loss is anticipated on a contract, the full amount of the anticipated loss is
provided for at that time.

                                       80
<PAGE>
    Revenues from standard software products are recognized upon shipment in
accordance with Statement of Position 97-2, "Software Revenue Recognition," as
amended by the Statement of Position 98-4. Revenues from maintenance agreements
are deferred and amortized over the life of the maintenance agreements.
AverStar's royalty income is derived from licensing agreements that AverStar has
with commercial companies. Typically, the amount of AverStar's royalty income is
based on a percentage of AverStar's customer's revenues for the products that
incorporate AverStar's technology. Per unit royalties earned from the license of
standard software products are recognized when received from the customer.
AverStar's royalty income does not represent a significant portion of its
revenues.

FISCAL PERIODS ENDED DECEMBER 31, 1997, DECEMBER 31, 1998, AND DECEMBER 31, 1999

    REVENUES.  For the 12 months ended December 31, 1999, AverStar's revenues
were $184.3 million compared to $121.1 million for the 12 months ended
December 31, 1998 and $53.6 million for the 10 months ended December 31, 1997,
representing a 244% increase over this period. Of the approximately $68 million
increase in revenues from December 31, 1997 to December 31, 1998, approximately
$39 million, or 57% of the increase, was the result of the acquisition of Pacer
which became effective February 27, 1998. Approximately $12 million, or 18% of
the increase, resulted from AverStar winning two contracts with the United
States Postal Service in mid-1997. AverStar benefited from the first full-year
effect of these contracts in 1998. The increased work under a contract awarded
by NASA in 1996 accounted for approximately $9 million, or 13% of the increase.
Revenues were also positively affected by increased business with commercial
customers, by new contracts with the National Institute of Health and the United
States Navy and by increased royalty income. Of the approximately $63 million
increase from December 31, 1998 to December 31, 1999, approximately $41 million
or 65% of the increase was the result of the acquisition of CBSI which became
effective March 18, 1999.

                                       81
<PAGE>
Approximately $7.5 million, or 12% of the increase, was attributable to the
inclusion of 12 months of Pacer's operations during 1999 compared to 10 months
in 1998. The remaining $14.5 million, or 23% of the increase, was a result of
internal growth and further expansion of the contracts listed above.

    COST OF REVENUES.  For the 12 months ended December 31, 1999, AverStar's
cost of revenues was $145.1 million compared to $93.6 million for the 12 months
ended December 31, 1998 and $41.7 million for the 10 months ended December 31,
1997, representing a 248% increase over this period. The increase primarily
resulted from higher labor costs to support a larger number of contracts due to
the acquisitions of Pacer and CBSI. As a percentage of revenues, cost of
revenues has not changed significantly: 78.7% for the period ended December 31,
1999, 77.3% for the period ended December 31, 1998 and 77.7% for the period
ended December 31, 1997.

    SELLING, GENERAL AND ADMINISTRATIVE EXPENSE.  For the 12 months ended
December 31, 1999, AverStar's selling, general and administrative expense,
including amortization expense, was $28.9 million compared to $20.6 million for
the 12 months ended December 31, 1998, and $10.4 million for the 10 months ended
December 31, 1997, representing an increase of $18.5 million, or 178%, over this
period. This increase is attributed to increased staff related to the
acquisition of Pacer and CBSI, and additional hiring of sales and marketing
staff. In addition, over this period, amortization expense increased from
$150,000 for the 10 months ended December 31, 1997 to $3.5 million for the
12 months ended December 31, 1999 due to the acquisitions of Pacer and CBSI. As
a percentage of revenues, SG&A expense decreased to 16% in the 12 months ended
December 31, 1999, from 17% in the 12 months ended December 31, 1998 and from
19% in the 10 months ended December 31, 1997, primarily because SG&A expense was
spread over a larger revenue base in 1999.

    INCOME FROM OPERATIONS.  For the 12 months ended December 31, 1999,
AverStar's income from operations was $10.3 million compared to $6.9 million for
the 12 months ended December 31, 1998, and $1.6 million for the 10 months ended
December 31, 1997, representing a 544% increase over this period. Of the
$8.7 million increase in income from operations over this period, approximately
$4.3 million of the increase was attributable to the acquisition of Pacer,
$3.3 million was attributable to the acquisition of CBSI, and $4.6 million was
attributable to internal growth. These increases were offset by $3.5 million of
amortization related to the acquisitions of Pacer and CBSI.

    NET INCOME FROM CONTINUING OPERATIONS.  For the 12 months ended
December 31, 1999, net income from continuing operations was $2.6 million
compared to $2.4 million for the 12 months ended December 31, 1998 and $198,000
for the 10 months ended December 31, 1997. The increase in net income from
continuing operations of $2.4 million over this period resulted from the
increase in income from operations of $8.7 million offset by a $3.4 million net
increase in interest expense, a one time offering expense of $845,000 and an
increase in taxes of $2.1 million. The increase in interest expense is
attributed to additional borrowing to partially fund the acquisition of Pacer
and CBSI and to support working capital needs. The increase in taxes resulted
from the increased operating income.

    NET INCOME.  For the 12 months ended December 31, 1999, AverStar's net
income was $2.6 million, compared to a net loss of $2.7 million for the
12 months ended December 31, 1998, and net loss of $1.5 million for the
10 months ended December 31, 1997. The net loss for 1998 resulted from income
from continuing operations of $2.4 million offset by a net loss from the
discontinued operations of $2.5 million and by a net loss on the disposal of
discontinued operations of $2.6 million. Similarly, the net loss for the ten
months ended December 31, 1997 was the result of income from continuing
operations of $198,000 and a net loss from discontinued operations of
$1.7 million.

    LIQUIDITY AND CAPITAL RESOURCES.  In March 1999, AverStar refinanced its
outstanding debt in conjunction with the purchase of CBSI. AverStar obtained a
$75.0 million credit facility from a group of lenders led by First Union
Commercial Corporation. This facility comprised $45.0 million in senior debt and
$30.0 million in revolving credit. In addition, AverStar maintains a
$5.0 million subordinated

                                       82
<PAGE>
debt agreement, which AverStar obtained in August 1995, with MassMutual.
AverStar's total debt capacity has a face value of $80 million. At December 31,
1999, AverStar's outstanding debt under these agreements was approximately
$57.1 million. The availability of approximately $20.6 million under the
revolving credit agreement is subject to covenants and collateral limitations.
At December 31, 1999, about $20.0 million of additional borrowing under the
revolving credit facility was available to AverStar based on the covenants and
limitations. AverStar's First Union Credit Facility is secured by the stock of
AverStar's subsidiaries, AverStar's accounts receivable and substantially all
AverStar's other assets. The agreements expire in March 2004 and March 2005.
Loans outstanding under these agreements bear interest at variable rates
generally based on LIBOR approximating 8.5% per year.

    BACKLOG.  Backlog represents management's estimate of AverStar's aggregate
realizable revenues over the term of all of AverStar's contracts, including any
option periods. However, backlog is not necessarily indicative of future
revenues. AverStar's contract backlog was approximately $350 million as of
December 31, 1999. AverStar's backlog is composed of:

    - Customer authorized contract values for which the customer has set aside,
      appropriated or committed funds for specifically identified services,
      products, tasks or delivery orders; and

    - Management's estimate, based on AverStar's past experience and long-term
      relationships with many of AverStar's customers, of the realizable
      contract values for all expected future services, products, tasks or
      delivery orders under our commercial contracts and single agency,
      Government Service Administration Schedule, multiple award and
      government-wide acquisition contracts, for which funds have not yet been
      set aside, appropriated or committed, even if our customer is not
      obligated to request any services under a contract.

    The actual timing of AverStar's receipt of revenues, if any, on projects
included in its backlog could change because many factors affect the scheduling
of projects. In addition, cancellations or adjustments to contracts may occur.
AverStar's backlog is subject to large variations from quarter to quarter as
existing contracts are renewed or new contracts are awarded. Additionally,
virtually all of AverStar's backlog represents contracts with the United States
government which may be terminated at any time for any reason.

    DISCONTINUED OPERATIONS.  In August 1997, AverStar combined its computer and
video game business with the operations of Looking Glass Technologies, Inc. to
form Intermetrics Entertainment Software, LLC, or IES. After the combination,
AverStar owned 66% of IES and consolidated the results of IES' operations with
AverStar's operations for AverStar's financial reporting purposes. In
December 1998, AverStar approved a plan of divestiture of IES by means of a
distribution of AverStar's interest in IES to AverStar's stockholders. AverStar
completed the distribution in March 1999. Please see note 3 to AverStar's
consolidated financial statements. As part of AverStar's plan of divestiture,
AverStar structured financial arrangements with IES that included the conversion
of $1.3 million of capital contributed to IES into a term loan, and the
establishment of a $2.0 million revolving credit facility for use by IES through
December 31, 1999. The term loan is equal to AverStar's capital contributed to
IES, reduced by the operating losses of IES during AverStar's ownership period.
AverStar converted the contributed capital to a term loan because the term loan
provides it with the possibility to recover some of the advances AverStar made
to IES without creating adverse tax consequences. The revolving credit facility
obligates AverStar to advance up to $2.0 million to IES through December 31,
1999. These advances must be made available at any time, for any amount up to
$2.0 million, as long as IES has not filed for bankruptcy and is not in the
process of liquidation or the equivalent. Amounts advanced under the term loan
and revolving credit facility and an additional $400,000 in term loans mature on
December 31, 2001. If not prepaid, AverStar will pursue collection of all
amounts due. However, AverStar presently does not believe that it will be
successful in its collection efforts.

    As a result of the plan of divestiture approved by AverStar in
December 1998 and completed in March 1999, AverStar has accounted for its
investment in IES as a discontinued operation in 1997 and 1998. For the five
months ended December 31, 1997, IES recorded revenues of $1.9 million and a net
loss from operations of $1.7 million. For the twelve months ended December 31,
1998, IES recorded revenues of $7.2 million and a net loss from operations of
$2.5 million. The increase in revenues in 1998 over 1997 was the result of a
full year of operations and a higher level of development activities supported
by advances of royalties from publishers of the games under development. The
increased loss in 1998 over 1997 is primarily attributable to the full year of
operations in 1998. The operating losses in both years were the result of the
increasing number of game development projects, for some of which the estimated
costs to complete the development exceeded the expected advances from
publishers, resulting in the recording of losses in current periods. The net
losses in both 1997 and 1998 are accounted for in AverStar's statement of
operations as losses from discontinued operations. In addition, AverStar
incurred a net loss from the disposal of IES of $2.6 million, $3.9 million on a
pre-tax basis, representing the write-off of $1.7 million of term loans,
$200,000 of professional fees, $500,000 of estimated operating losses through
the disposal date and the accrual of our remaining estimated funding commitment
of $1.5 million described in the preceding paragraph.

    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.  AverStar's
exposure to market risk relates to changes in interest rates for borrowings
under its senior term loans and its revolving credit facility. These borrowings
bear interest at variable rates. The unsecured notes bear interest at a fixed
rate. Based on AverStar's borrowings during 1998, a hypothetical 10% increase in
interest rates would have increased AverStar's annual interest expense by
approximately $250,000 and would have decreased AverStar's annual cash flow from
operations by approximately $150,000.

    IMPACT OF YEAR 2000.  In late 1999, the Company completed its remediation
and testing of systems to determine that such systems were Year 2000 ready. As a
result of those planning and implementation efforts, the Company experienced no
significant disruptions in mission critical information technology and
non-information technology systems and believes those systems successfully
responded to the Year 2000 date change. The Company expensed approximately
$200,000 during 1999 in connection with remediating its systems. The Company is
not aware of any material problems resulting from Year 2000 issues, either with
its products, its internal systems, or the products and services of third
parties. The Company will continue to monitor its mission critical computer
applications and those of its suppliers and vendors throughout the year 2000 to
ensure that any latent Year 2000 matters that may arise are addressed promptly.

    PENDING ACCOUNTING PRONOUNCEMENTS.  In June 1998, the Financial Accounting
Standards Board issued Statement No. 133 (FAS 133), "Accounting for Derivative
Investments and Hedging Activities," which required adoption for fiscal years
beginning after June 15, 1999. FAS 133 was subsequently amended by Statement of
Financial Accounting Standards No. 137, "Accounting for Derivative Instruments
and Hedging activities--Deferral of the Effective Date of FASB Statement
No. 133," and now will be effective for fiscal years beginning after June 15,
2000, with earlier adoption permitted. The adoption of FAS 133 is not expected
to have a material impact on the results of operations or financial position of
AverStar.

    In December 1999, the Securities Exchange Commission issued Staff Accounting
Bulletin 101 (SAB 101), "Revenue Recognition in Financial Statements." SAB 101
summarizes the application of generally accepted accounting principles to
revenue recognition in financial statements. On March 24, 2000, the SEC issued
an Amendment to SAB 101 (SAB 101A), delaying the effective date for certain
companies. AverStar will adopt SAB 101 in the second quarter of fiscal 2000 and
is presently analyzing what impact, if any, SAB 101 will have on the results of
operations or financial position of AverStar.

THREE MONTH PERIODS ENDED MARCH 31, 2000 AND 1999



    The results of operations for the three months ended March 31, 2000 include
the activity of MJR Associates, Inc., since the date of acquisition, March 10,
2000. The results of operations for the three months ended March 31, 1999
include the activity of Computer Based System, Inc., or CBSI, since the date of
acquisition, March 18, 1999.



    REVENUES. For the three months ended March 31, 2000 AverStar's revenues were
$46.2 million compared to $36.3 million for the three months ended March 31,
1999. Of the $9.9 million increase, approximately $12.6 million related to the
acquisition of CBSI and approximately $1.2 million related to the acquisition of
MJR. These increases were offset by a reduction of approximately $3.9 million in
Year 2000 readiness services.



    COST OF REVENUES. For the three months ended March 31, 2000 AverStar's cost
of revenues was $36.5 million compared to $28.8 million for the three months
ended March 31, 1999. The increase of $7.7 million is primarily attributable to
the CBSI and MJR acquisitions. As a percentage of revenues, cost of revenues was
essentially flat at 79.1% for the three months ended March 31, 2000 compared to
79.4% for the three months ended March 31, 1999.



    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. For the three months ended
March 31, 2000 AverStar's selling, general and administrative expense was $7.6
million compared to $5.3 million for the three months ended March 31, 1999, an
increase of $2.3 million. Amortization of goodwill increased to $968,000 for the
three months ended March 31, 2000, compared to $357,000 for the three months
ended March 31, 1999. This increase reflects three months of amortization for
CBSI and 21 days of amortization for MJR for the three months ended March 31,
2000 compared to 10 days of amortization for CBSI for the three months ended
March 31, 1999. The remaining increase of $1.7 million is associated with the
increase in staff from the CBSI and MJR acquisitions and growth in the sales and
marketing functions during 1999.



    INCOME FROM OPERATIONS. For the three months ended March 31, 2000,
AverStar's income from operations was $2.0 million compared with $2.2 million
for the three months ended March 31, 1999. Income from operations related to
CBSI and MJR activities were approximately $1,053,000 and $173,000 for the three
months ended March 31, 2000, respectively, compared to none for the three months
ended March 31, 1999. This increase was offset by the increase in amortization
expense of $611,000, investment of approximately $300,000 in the development of
the eTective business and a reduction of approximately $500,000 in Year 2000
related services.



    INCOME BEFORE INCOME TAXES. For the three months ended March 31, 2000.
AverStar's income before income taxes was $601,000 compared to $1.4 million for
the three months ended March 31, 1999. This decrease is attributable to the
lower income from operations and an increase in interest expense of $687,000 for
the three months ended March 31, 2000 compared to the three months ended
March 31, 1999. The increase in interest expense for the three months ended
March 31, 2000 resulted from additional borrowings to fund the acquisitions of
CBSI and MJR, and to support working capital requirements.



    NET INCOME. For the three months ended March 31, 2000, AverStar's net income
was $331,000 compared to $792,000 for the three months ended March 31, 1999. The
income tax provision reflects a 45% effective tax rate for the three months
ended March 31, 2000 and 1999. The effective tax rate is higher than the
statutory rate of 40% primarily because of non-deductible amortization of
goodwill.



    LIQUIDITY AND CAPITAL RESOURCES. In March 1999, AverStar obtained a $75.0
million credit facility from a group of lenders led by First Union Commercial
Corporation. This facility is comprised of $45.0 million in senior debt and
$30.0 million in revolving credit. In addition, AverStar maintains a $5.0
million subordinated debt agreement, which AverStar obtained in August 1995,
with MassMutual. AverStar's total debt capacity has a face value of $80 million.
At March 31, 2000, AverStar's outstanding debt under these agreements was
approximately $68.3 million. At March 31, 2000, approximately $8.7 million of
additional borrowing under the revolving credit facility was available to
AverStar based on the covenants and limitations. AverStar's First Union Credit
Facility is secured by the stock of AverStar's subsidiaries and substantially
all of AverStar's assets. The agreements expire in March 2004 and March 2005.
Loans outstanding under these agreements bear interest at variable rates
generally based on LIBOR (9% at March 31, 2000).

 (2) The information regarding beneficial ownership of Titan common stock has
     been presented according to rules of the SEC and is not necessarily
     indicative of beneficial ownership for any other purpose. Under the SEC
     rules, beneficial ownership of Titan common stock includes any shares as to
     which a person has sole or shared voting power or investment power and also
     any shares which a person has the right to acquire within 60 days through
     the exercise of any stock option or other right. Under California and some
     other state laws, personal property owned by a married person may be
     community property that either spouse may manage and control. Titan has no
     information as to whether any shares shown in this table are subject to
     such community property laws.

 (3) Percentage of beneficial ownership as to any person as of a particular date
     is calculated by dividing the number of shares beneficially owned by that
     person by the sum of the number of shares outstanding as of such date and
     the number of shares as to which that person has the right to acquire
     voting or investment power with respect to their shares. Information with
     respect to beneficial owners of more than 5% of the common stock is based
     upon the most recent Schedule 13D or Schedule 13G on file with the SEC.

                       DESCRIPTION OF TITAN CAPITAL STOCK


    Titan's authorized capital stock currently consists of 100,000,000 shares of
common stock, par value $.01 per share, of which 50,737,637 shares were
outstanding as of May 19, 2000, and 2,500,000 shares of preferred stock, par
value $1.00 per share. Of the 2,500,000 authorized shares of Titan preferred
stock, 250,000 shares have been designated as series A junior participating
preferred stock, none of which have been issued as of the date hereof, and
1,068,102 shares have been designated as $1.00 cumulative convertible preferred
stock, $1.00 par value per share, 692,900 of which were issued and outstanding
as of May 19, 2000. If passed by the required number of votes at Titan's annual
meeting to be held on May 30, 2000, Titan will amend its certificate of
incorporation to increase the number of authorized shares of Titan's common
stock to 200,000,000 and to increase the number of authorized shares of Titan
preferred stock to 5,000,000.


    The following summary description of Titan's capital stock and its
shareholder rights plan is not complete and is subject to the provisions of the
Titan certificate of incorporation and bylaws, the rights agreement described
below and the provisions of applicable law. Copies of these documents have been
filed as part of, or incorporated by reference as exhibits to, the registration
statement of which this proxy statement/prospectus is a part and may be obtained
as described under "Where You Can Find More Information."

COMMON STOCK

    DIVIDENDS.  Subject to the right of the holders of any class of preferred
stock, holders of shares of Titan common stock are entitled to receive dividends
that may be declared by Titan's board of directors out of legally available
funds. No dividend may be declared or paid in cash or property on any share of
any class of common stock unless sumultaneously the same dividend is declared or
paid on each share of that and every other class of common stock; provided,
that, in the event of stock dividends, holders of a specific class of common
stock shall be entitled to receive only additional shares of that class.

    VOTING RIGHTS.  Holders of Titan common stock are entitled to one vote for
each share held. Holders do not have cumulative voting rights.

    LIQUIDATION RIGHTS.  Upon Titan's liquidation, dissolution or winding-up,
the holders of Titan common stock are entitled to share ratably in all assets
avaible for distribution after payment in full to creditors and holders of Titan
preferred stock, if any.

    OTHER PROVISION.  The holders of Titan common stock are not entitled to
preemptive or similar rights.

PREFERRED SHARE PURCHASE RIGHTS

    Each outstanding share of Titan common stock has or will have attached to it
one preferred share purchase right, which we refer to as a right. Each right
entitles the registered holder of common stock to purchase from Titan, upon the
occurrence of specified events, one one-hundredth of a share of series A junior
participating preferred stock of Titan, which we refer to as the participating
preferred shares, at a price of $42 per one one-hundredth of a participating
preferred share, subject to adjustment. The terms of the rights are set forth in
a rights agreement dated as of August 21, 1995 between Titan and American Stock
Transfer and Trust Company, as rights agent.

    Until the distribution date described below, Titan will not issue separate
certificates evidencing the rights. Until that date, the rights will be
evidenced, with respect to any common stock certificate, by

                                       91
<PAGE>
that common stock certificate. The rights will detach from the common stock and
a distribution date will occur upon the earlier of the following dates:

    - subject to the exceptions described below, the tenth day following a
      public announcement that an "acquiring person," which, subject to the
      exceptions listed in the following sentence, includes a person or "group"
      of affiliated or associated persons, has acquired, or obtained the right
      to acquire, beneficial ownership of 15% or more of the outstanding common
      stock, or

    - the tenth day following the commencement, or the first public announcement
      by any person or group of an intention to commence, a tender offer or
      exchange offer that would result in beneficial ownership by a person or
      group of 15% or more of the outstanding common stock.

    The Titan board of directors, with the concurrence of a majority of the
continuing directors, may postpone the distribution date by determining a later
distribution date before the time any person or group becomes an acquiring
person. Any board member who is not an acquiring person or an affiliate or
associate of an acquiring person, or an employee, director, representative,
nominee or designee of an acquiring person, or its affiliate or associate, but
who:

    - was a member of the Titan board of directors before any person becomes an
      acquiring person; or

    - became a member of the Titan board of directors after any person becomes
      an acquiring person if the member was nominated for election or elected to
      the Titan board of directors upon the recommendation or approval of a
      majority of the continuing directors,

is considered to be a continuing director of Titan.

    The term "acquiring person" does not include Titan, any subsidiary of Titan,
any employee benefit plan of Titan or of any subsidiary of Titan, or any entity
holding Titan common stock for or under an employee benefit plan of Titan or any
of its subsidiaries. In addition, a person who would otherwise be an acquiring
person will not be considered an acquiring person if the Titan board of
directors determines in good faith that such person inadvertently became the
beneficial owner of 15% or more of the Titan common stock and such person
divests itself, as promptly as practicable, of beneficial ownership of a
sufficient number of shares of Titan common stock so that it would no longer
otherwise qualify as an acquiring person.

    The rights agreement provides that, until the distribution date, or earlier
redemption or expiration of the rights, the rights will be transferred only with
the Titan common stock. The rights will be evidenced, with respect to any common
stock certificate outstanding as of September 7, 1995, by that common stock
certificate with a summary of the rights attached to it. Until the distribution
date, or earlier redemption or expiration of the rights, new common stock
certificates issued after September 7, 1995 upon transfer or new issuances of
common stock will contain a notation incorporating the rights agreement by
reference. Until the distribution date, the surrender for transfer of any
certificates for common stock, even without a summary of the rights attached to
it, also will constitute the transfer of the rights associated with the common
stock represented by that certificate. As soon as practicable after the
distribution date, separate certificates evidencing the rights will be mailed to
holders of record of the Titan common stock as of the close of business on the
distribution date, and the separate right certificates alone will evidence the
rights. Only Titan common stock issued before the distribution date will be
issued with rights.

    The rights are not exercisable until the distribution date. The rights will
expire on August 17, 2005, unless the expiration date is extended or unless the
rights are earlier redeemed or exchanged by Titan, in each case as described
below.

    The purchase price payable for the participating preferred shares, and the
number of participating preferred shares or other securities or property
issuable, upon exercise of the rights, as well as the

                                       92
<PAGE>
number of rights outstanding, are subject to adjustment from time to time to
prevent dilution in the following circumstances:

    - in the event of a stock dividend on, or a subdivision, combination or
      reclassification of the participating preferred shares,

    - upon the grant to holders of the participating preferred shares of rights
      or warrants to subscribe for or purchase participating preferred shares at
      a price, or securities convertible into participating preferred shares
      with a conversion price, less than the current market price of the
      participating preferred shares, or

    - upon the distribution to holders of the participating preferred shares of
      evidences of indebtedness, securities or assets, excluding regular
      periodic cash dividends at a rate not in excess of 125% of the last cash
      dividend paid or, in the case that regular cash dividends have not been
      paid, at a rate not in excess of 50% of the average net income per share
      of the four quarters ended immediately before the payment of the dividend,
      or dividends payable in participating preferred shares or of subscription
      rights or warrants, other than those referred to above.

The number of outstanding rights and the number of one one-hundredths of a
participating preferred share issuable upon exercise of each right are also
subject to adjustment in the event of a dividend or other distribution on the
common stock payable in common stock or subdivisions, consolidations or
combinations of Titan common stock occurring, in any of those cases, before the
distribution date.

    Participating preferred shares purchasable upon exercise of the rights will
not be redeemable. Each participating preferred share will be entitled to a
minimum preferential quarterly dividend payment of $1.00 per share, but will be
entitled to an aggregate dividend of 100 times the dividend declared per share
of Titan common stock. If there is a liquidation, the holders of the
participating preferred shares will be entitled to a minimum preferential
liquidation payment of $100 per share, but will be entitled to an aggregate
payment of 100 times the payment made per share of Titan common stock. Each
participating preferred share will have 100 votes, voting together with the
Titan common stock. If there is a merger, consolidation or other transaction in
which Titan common stock is exchanged, each participating preferred share will
be entitled to receive 100 times the amount received per share of Titan common
stock. These rights are protected by customary antidilution provisions.

    Because of the nature of the dividend, liquidation and voting rights of the
participating preferred shares, the value of the one one-hundredth interest in a
participating preferred share purchasable upon exercise of each right should
approximate the value of one share of Titan common stock.

    If any person or group becomes an acquiring person, except pursuant to
specified cash offers for all outstanding shares of Titan common stock approved
by the Titan board of directors, or if Titan is the surviving corporation in a
merger with an acquiring person or any affiliate or associate of an acquiring
person and Titan common stock is not changed or exchanged, proper provision will
be made so that each holder of a right, other than rights beneficially owned by
the acquiring person, which will become null and void, will have the right to
receive upon exercise of the right at the then-current market price, instead of
participating preferred shares, that number of shares of Titan common stock
having a market value of two times the exercise price of the right. If Titan
does not have sufficient common stock issued but not outstanding, or authorized
but unissued, to permit the exercise in full of the rights, Titan will be
required to take all action necessary to authorize additional common stock for
issuance upon exercise of the rights. If, after a good-faith effort, Titan is
unable to take all necessary action, Titan will substitute, for each share of
common stock that would otherwise be issuable upon exercise of a right, a number
of participating preferred shares, or fractional participating preferred shares,
with the same market value as that share of common stock.

                                       93
<PAGE>
    If, after a person or group has become an acquiring person, Titan is
acquired in a merger or other business combination transaction or 50% or more of
its consolidated assets or earning power are sold, proper provision will be made
so that each holder of a right, other than rights beneficially owned by the
acquiring person, which will become null and void, will have the right to
receive, upon the exercise of the right at its then-current exercise price and
instead of participating preferred shares, that number of shares of common stock
of the acquiring company, or its parent, which at the time of the transaction
will have a market value of two times the exercise price of the right.

    The exercise price of a right at any date will be equal to the purchase
price at that date multiplied by the number of one one-hundredths of a
participating preferred share for which a right is exercisable at that date.

    At any time after any person or group becomes an acquiring person and before
the acquisition by that person or group of 50% or more of the outstanding Titan
common stock, the Titan board of directors may exchange the rights, in whole or
in part, for a number of shares of Titan common stock, per right, having an
aggregate value equal to the excess of the value of the shares of Titan common
stock issuable upon exercise of a right after a person or group becomes an
acquiring person over the purchase price, subject to adjustment. The Titan board
of directors will not exchange the rights owned by the acquiring person or
group, which will have become null and void.

    With specified exceptions, no adjustments in the purchase price for the
preferred shares will be required until cumulative adjustments require an
adjustment of at least 1% of that purchase price. No fractional participating
preferred shares will be issued, other than fractions which are integral
multiples of one one-hundredth of a participating preferred share, which may, at
the election of Titan, be evidenced by depositary receipts. Instead of issuing
fractional participating preferred shares, Titan will make an adjustment in cash
based on the market price of the participating preferred shares on the last
trading day before the date of exercise.

    Upon approval by its board of directors, Titan may redeem the rights, in
whole, but not in part, at a price of $.01 per right at any time until ten days
following the public announcement that a person or group has become an acquiring
person. The Titan board of directors, with the concurrence of a majority of the
continuing directors, may extend the period during which the rights are
redeemable beyond the ten days following the public announcement that a person
or group has become an acquiring person. Under circumstances described in the
rights agreement, the decision to redeem will require the concurrence of a
majority of the continuing directors. Immediately upon the determination of the
Titan board of directors to redeem the rights, Titan will make an announcement
of the redemption. Upon the redemption, the right to exercise the rights will
terminate and the only right of right holders will be to receive the redemption
price.

    Until a right is exercised, the holder of the right, in the capacity of a
holder, will have no rights as a stockholder of Titan, including, without
limitation, the right to vote or to receive dividends. Although the distribution
of the rights will not be taxable to stockholders or to Titan, stockholders may,
depending upon the circumstances, recognize taxable income in the event that the
rights become exercisable for Titan common stock or other consideration, or for
common stock of the acquiring company or its parent as set forth above.

    Any of the provisions of the rights agreement may be amended or supplemented
by the Titan board of directors before the distribution date. From and after the
distribution date, Titan and the rights agent may amend or supplement the rights
agreement from time to time without the approval of any holders of rights

    - to cure any ambiguity, to correct or supplement any defective or
      inconsistent provisions,

                                       94
<PAGE>
    - to shorten or lengthen any time period under the rights agreement relating
      to when the rights may be redeemed, so long as, under specified
      circumstances, a majority of the continuing directors approve the
      shortening or lengthening, or

    - to make any other provisions with respect to the rights which Titan and
      the rights agent may deem necessary or desirable.

Notwithstanding this right to amend or supplement, from and after the
distribution date, the rights agreement may not be amended in any manner which
would adversely affect the interest of the holders of rights.

PREFERRED STOCK

    Under the Titan certificate of incorporation, the board of directors has the
authority, without further action by Titan stockholders, to issue up to
2,500,000 shares of preferred stock in one or more series and to fix the voting
powers, designations, preferences and the relative participating, optional or
other special rights and qualifications, limitations and restrictions of each
series, including dividend rights, conversion rights, voting rights, terms of
redemption, liquidation preferences and the number of shares constituting any
series. Of the preferred stock currently outstanding, the board of directors has
fixed the terms of the participating preferred shares issuable upon exercise of
the rights and the $1.00 cumulative convertible preferred stock. Because the
board of directors has the power to establish the preferences and rights of the
shares of any additional series of preferred stock, it may afford holders of any
preferred stock preferences, powers and rights, including voting rights, senior
to the rights of holders of the common stock, which could adversely affect the
holders of the common stock.

    CUMULATIVE CONVERTIBLE PREFERRED STOCK

    DIVIDENDS.  Each share of cumulative convertible preferred stock accrues
dividends at the rate of $1.00 per share per annum.

    VOTING RIGHTS.  Holders of Titan cumulative convertible preferred stock are
entitled to one-third of one vote for each share held. Holders do not have
cumulative voting rights.

    LIQUIDATION RIGHTS.  Upon Titan's liquidation, dissolution or winding-up,
the holders of cumulative convertible preferred stock are entitled to a
liquidation preference of $20 per share plus any unpaid cumulative dividends
before any distribution to holders of Titan common stock.

    CONVERSION RIGHTS.  Each outstanding share of cumulative convertible
preferred stock is convertible into Titan common stock, at the option of the
holder, at a rate of two-thirds shares of common stock for each share of
cumulative convertible preferred stock.

    REDEMPTION.  Each share of cumulative convertible preferred stock is
redeemable, but only at Titan's option, at a redemption price of $20 per share
plus any accrued and unpaid dividends.

    OTHER PROVISIONS.  The holders of Titan cumulative convertible preferred
stock are not entitled to preemptive or similar rights.

ANTI-TAKEOVER EFFECT OF TITAN'S BYLAW PROVISIONS

    The Titan bylaws contain provisions that could make it more difficult to
consummate an acquisition of Titan by means of a tender offer, a proxy contest
or otherwise.

    STOCKHOLDER ACTION BY WRITTEN CONSENT.  The Titan bylaws provide that
stockholder action may be taken by written consent instead of a meeting, but
only upon compliance with advance notice and other procedural requirements
specified in the bylaws. Any Titan stockholder of record seeking to have the
stockholders authorize or take corporate action by written consent must, by
written notice to Titan's

                                       95
<PAGE>
secretary, request the Titan board of directors to fix a record date for the
purpose of determining the stockholders entitled to consent to the action in
writing without a meeting. Within ten days of receiving the notice, the Titan
board of directors must adopt a resolution fixing the record date, which must
not precede, or be more than ten days after, the date of the resolution. If the
Titan board of directors does not fix a record date in this manner, the record
date:

    - when no prior action by the Titan board of directors is required by
      applicable law, will be the first date on which a signed written consent
      describing the action taken or proposed to be taken is delivered to Titan;
      or

    - when prior action by the Titan board of directors is required by
      applicable law, will be at the close of business on the date on which the
      Titan board of directors adopts the resolution taking the prior action.

In addition, the bylaws provide that no stockholder action by written consent is
effective until nationally recognized inspectors of election certify to Titan
that the consents properly delivered to Titan represent at least the minimum
number of votes that would be necessary to take the corporate action. All
stockholder consents must be properly delivered to Titan within 60 days of the
date that the earliest dated written consent was received by Titan.

    Compliance with these requirements or the failure of Titan stockholders to
satisfy any of the requirements could delay, prevent or invalidate stockholder
action.

    STOCKHOLDER ADVANCE NOTICE PROCEDURE.  The Titan bylaws establish an advance
notice procedure for stockholders to make nominations of candidates for election
as directors before an annual or special meeting of Titan stockholders or to
bring other business before an annual meeting of Titan stockholders. Titan
stockholders are not authorized to bring other business before a special meeting
of Titan stockholders and are only authorized to make nominations of candidates
for election as directors before a special meeting when the election of
directors at the special meeting has been authorized by or at the direction of
the Titan board of directors.

    The stockholder notice procedures provide that only persons who are
nominated by or at the direction of the Titan board of directors or by a
stockholder who has given timely written notice to the secretary of Titan before
the meeting at which directors are to be elected will be eligible for election
as directors. The notices required for a stockholder to nominate a person for
election as a director at any annual meeting or at special meetings which the
Titan board of directors has determined that directors will be elected include
specified information about the stockholder and each proposed director nominee,
a description of all arrangements or understandings between the stockholder and
each proposed nominee and any other persons, other information regarding each
proposed nominee that would be required to be included in a proxy statement
filed under SEC rules and regulations, and the written consent of each proposed
nominee to serve as a director if elected. The stockholder notice procedure also
provides that the only business that may be conducted at an annual meeting is
business which has been brought before the meeting by, or at the direction of,
the board of directors or by a stockholder who has given timely written notice
to the secretary of Titan. This notice is required to include a brief
description of the business desired to be brought before the meeting, any
material interest of the stockholder in that business, and specified information
about the stockholder and the stockholder's ownership of Titan capital stock.

SECTION 203 OF THE DELAWARE GENERAL CORPORATION LAW

    Titan is subject to section 203 of the Delaware General Corporation Law,
which, with specified exceptions, prohibits a Delaware corporation from engaging
in any "business combination" with any

                                       96
<PAGE>
"interested stockholder" for a period of three years following the time that the
stockholder became an interested stockholder unless:

    - before that time, the board of directors of the corporation approved
      either the business combination or the transaction which resulted in the
      stockholder becoming an interested stockholder;

    - upon completion of the transaction which resulted in the stockholder
      becoming an interested stockholder, the interested stockholder owned at
      least 85% of the voting stock of the corporation outstanding at the time
      the transaction commenced, excluding for purposes of determining the
      number of shares outstanding those shares owned by persons who are
      directors and also officers and by employee stock plans in which employee
      participants do not have the right to determine confidentially whether
      shares held subject to the plan will he tendered in a tender or exchange
      offer; or

    - at or after that time, the business combination is approved by the board
      of directors and authorized at an annual or special meeting of
      stockholders, and not by written consent, by the affirmative vote of at
      least 66 2/3% of the outstanding voting stock which is not owned by the
      interested stockholder.

    Section 203 defines "business combination" to include the following:

    - any merger or consolidation of the corporation with the interested
      stockholder;

    - any sale, transfer, pledge or other disposition of 10% or more of the
      assets of the corporation involving the interested stockholder;

    - subject to specified exceptions, any transaction that results in the
      issuance or transfer by the corporation of any stock of the corporation to
      the interested stockholder;

    - any transaction involving the corporation that has the effect of
      increasing the proportionate share of the stock of any class or series of
      the corporation beneficially owned by the interested stockholder; or

    - any receipt by the interested stockholder of the benefit of any loans,
      advances, guarantees, pledges or other financial benefits provided by or
      through the corporation.

    In general, section 203 defines an "interested stockholder" as any entity or
person beneficially owning 15% or more of the outstanding voting stock of the
corporation and any entity or person affiliated with or controlling or
controlled by that entity or person.

DIRECTOR LIABILITY AND INDEMNIFICATION OF DIRECTORS AND OFFICERS

    The Delaware General Corporation Law provides that a corporation may
eliminate or limit the personal liability of each director to the corporation or
its stockholders for monetary damages for breach of fiduciary duty as a director
except for liability for any breach of the director's duty of loyalty to the
corporation or its stockholders, for acts or omissions not in good faith or that
involve intentional misconduct or a knowing violation of law, in respect of
unlawful dividend payments or stock redemptions or repurchases, and for any
transaction from which the director derives an improper personal benefit. The
Titan certificate of incorporation provides for the elimination and limitation
of the personal liability of directors for monetary damages to the fullest
extent permitted by the Delaware General Corporation Law. In addition, the
certificate of incorporation provides that if the Delaware General Corporation
Law is amended to authorize the further elimination or limitation of the
liability of a director, then the liability of the directors will be eliminated
or limited to the fullest extent permitted by the Delaware General Corporation
Law, as so amended. The effect of this provision is to eliminate the rights of
Titan and its stockholders, through stockholder derivative suits on behalf of

                                       97
<PAGE>
Titan, to recover monetary damages against a director for breach of the
fiduciary duty of care as a director, including breaches resulting from
negligent or grossly negligent behavior, except in the situations described
above. The provision does not limit or eliminate the rights of Titan or any
stockholder to seek non-monetary relief such as an injunction or rescission upon
breach of a director's duty of care. This provision is consistent with
section 102(b)(7) of the Delaware General Corporation Law, which is designed,
among other things, to encourage qualified individuals to serve as directors of
Delaware corporations.

    The Titan bylaws provide that, to the full extent permitted by Delaware
General Corporation Law, Titan will indemnify, and advance expenses to, each of
its currently acting and former directors and officers, employees and agents.

                    COMPARATIVE RIGHTS OF TITAN STOCKHOLDERS
                           AND AVERSTAR STOCKHOLDERS

    AverStar is a Delaware corporation and a private company, and your rights as
an AverStar stockholder are governed by the Delaware General Corporation Law and
AverStar's certificate of incorporation, bylaws and the Stockholders Agreement
between AverStar and the stockholders listed therein. Following the merger,
AverStar stockholders will be common stockholders of Titan, which is a Delaware
corporation and a public company. Your rights as a Titan stockholder will
continue to be governed by the Delaware General Corporation Law, but also will
be governed by Titan's certificate of incorporation, bylaws and shareholder
rights agreement, which is referred to as the rights agreement. For more
information on Titan's organizational documents, see "Description of Titan
Capital Stock."

    Significant differences, which Titan and AverStar believe are all the
material differences, between the rights of Titan stockholders and AverStar
stockholders are summarized below. This summary is not an exhaustive list or
detailed description of the provisions discussed and is qualified in its
entirety by Titan's certificate of incorporation, bylaws and rights agreement,
and AverStar's certificate of incorporation, bylaws and Stockholders Agreement,
each of which you should review carefully. Copies of these documents may be
obtained as described under "Where You Can Find More Information."

    The following summary describes the rights of AverStar stockholders prior to
the consolidation of all classes of AverStar common stock into one class of
common stock. See "Terms of the Merger Agreement and Related
Transactions--General--Conversion of AverStar Common Stock." In addition, the
Stockholders Agreement will terminate upon the completion of the merger.

AUTHORIZED SHARES OF CAPITAL STOCK; DIVIDEND RIGHTS; OTHER DISTRIBUTIONS

VOTING RIGHTS

    TITAN.  Subject to the voting rights of holders of any then outstanding
Titan preferred stock, each share of Titan common stock is entitled to one vote
on each matter submitted to a vote of the stockholders of Titan. Shares of Titan
common stock are not entitled to any cumulative voting rights.

    Each holder of Titan's $1.00 cumulative convertible preferred stock is
entitled to one-third vote per share of such stock. Holders of the common stock
and the $1.00 cumulative convertible preferred stock generally vote as a single
class.

    AVERSTAR.  The AverStar certificate of incorporation and bylaws provide that
the holders of Voting Class A Common Stock, Voting Class B Common Stock, Voting
Class C Common Stock, Voting Class D Common Stock, Voting Class E Common Stock
and Voting Class F Common Stock shall vote together as one class on all matters
presented to the stockholders. Each share of AverStar common stock is entitled
to one vote. Any non-voting common stock may be converted at any time at the
option of the holder for one share of voting common stock of the same class
except that each share of Class G Non-Voting Common Stock may be converted into
shares of Voting Class D Common Stock or shares of Non-Voting Class D Common
Stock at any time at the option of the holder, initially at a rate of one share
of Class D Common Stock for one share of Class G Common Stock, as such rate may
be adjusted from time to time by certain anti-dilution provisions. Shares of
AverStar common stock are not entitled to any cumulative voting rights.

PREEMPTIVE RIGHTS

    TITAN.  Titan common stock has no preemptive rights enabling a holder to
subscribe for or receive shares of any class of stock of Titan or any other
securities convertible into shares of any class of stock of Titan under Titan's
certificate of incorporation.

    AVERSTAR.  Each AverStar stock holder is entitled to preemptive rights under
AverStar's Stockholders Agreement to purchase on a pro rata basis any "new
securities" or "new stock" that AverStar proposes to issue for the purpose of
raising additional private capital. New securities and new stock include any
shares of AverStar common stock, any rights or options to purchase shares of

                                      100
<PAGE>
common stock and any securities that may be converted into shares of common
stock, except that the definitions of new securities and new stock do not
include securities or stock issued:

    - pursuant to any employment agreement;

    - for the purpose of acquiring another company;

    - pursuant to any incentive stock option plans; or

    - by reason of the provisions with respect to the Class G Common Stock in

BUSINESS COMBINATIONS; SUPERMAJORITY VOTING REQUIREMENTS

    Titan and AverStar are subject to section 203 of the Delaware General
Corporation Law, which, with specified exceptions, prohibits a Delaware
corporation from engaging in any "business combination" with any "interested
stockholder" for a period of three years following the time that the stockholder
became an interested stockholder unless:

    - before that time, the board of directors of the corporation approved
      either the business combination or the transaction which resulted in the
      stockholder becoming an interested stockholder;

    - upon completion of the transaction which resulted in the stockholder
      becoming an interested stockholder, the interested stockholder owned at
      least 85% of the voting stock of the corporation outstanding at the time
      the transaction commenced, excluding for purposes of determining the
      number of shares outstanding those shares owned by persons who are
      directors and also officers and by employee stock plans in which employee
      participants do not have the right to determine confidentially whether
      shares held subject to the plan will be tendered in a tender or exchange
      offer; or

    - at or after that time, the business combination is approved by the board
      of directors and authorized at an annual or special meeting of
      stockholders, and not by written consent, by the affirmative vote of at
      least 66 2/3% of the outstanding voting stock which is not owned by the
      interested stockholder.

    Section 203 defines "business combination" to include the following:

    - any merger or consolidation of the corporation with the interested
      stockholder;

    - any sale, transfer, pledge or other disposition of 10% or more of the
      assets of the corporation involving the interested stockholder;

    - subject to specified exceptions, any transaction that results in the
      issuance or transfer by the corporation of any stock of the corporation to
      the interested stockholder;

    - any transaction involving the corporation that has the effect of
      increasing the proportionate share of the stock of any class or series of
      the corporation beneficially owned by the interested stockholder; or

    - any receipt by the interested stockholder of the benefit of any loans,
      advances, guarantees, pledges or other financial benefits provided by or
      through the corporation.

In general, section 203 defines an "interested stockholder" as any entity or
person beneficially owning 15% or more of the outstanding voting stock of the
corporation and any entity or person affiliated with or controlling or
controlled by that entity or person.

    TITAN.  Titan's certificate of incorporation and bylaws do not have
supermajority or other special voting requirements for business combinations or
other transactions.

                                      101
<PAGE>
    AVERSTAR.  Averstar's Stockholders Agreement requires that a majority of
AverStar's board of directors, including at least one of the designees of John
C. Rennie and/or Signmund Goldblum, approve an extraordinary transaction.
AverStar's certificate of incorporation and bylaws also do not have
supermajority or other special voting requirements for business combinations or
other transactions.

APPRAISAL RIGHTS

    TITAN.  Titan's certificate of incorporation does not provide for appraisal
rights other than those rights designated by the Delaware General Corporation
Law. The Delaware General Corporation Law provides for appraisal rights only in
the case of specified mergers or consolidations and not, unless the certificate
of incorporation of a corporation so provides, in the case of other mergers, a
sale or transfer of all or substantially all of its assets or an amendment to
its certificate of incorporation. In addition, the Delaware General Corporation
Law does not provide appraisal rights in connection with a merger or
consolidation, unless the certificate of incorporation of a corporation so
provides, to the holders of shares of a constituent corporation listed on a
national securities exchange, or designated as a national market system security
by the National Association of Securities Dealers, Inc., or held of record by
more than 2,000 stockholders, unless the applicable agreement of merger or
consolidation requires the holders of those shares to receive, in exchange for
those shares, any property other than shares of stock of the resulting or
surviving corporation, shares of stock of any other corporation listed on a
national securities exchange or designated as described above, or held of record
by more than 2,000 holders, cash in lieu of fractional shares or any combination
of the foregoing. The Delaware General Corporation Law also denies appraisal
rights to the stockholders of the surviving corporation in a merger if such
merger did not require approval by the stockholders of the surviving
corporation.

    AVERSTAR.  AverStar's certification of incorporation does not provide for
appraisal rights other than those rights designated by the Delaware General
Corporation Law, as summarized above.

SPECIAL MEETINGS OF STOCKHOLDERS

    TITAN.  Titan's bylaws provide that special meetings may be called by Titan
pursuant to Titan's notice of meeting provisions. The stockholders of Titan do
not have the right to request or call a special meeting of stockholders, but a
stockholder may nominate persons for election as directors at a special meeting
called by Titan for the purpose of electing directors if the stockholder
complies with the advance notice provisions of the bylaws. For information on
these procedures, see "Description of Titan Capital Stock--Stockholder Advance
Notice Procedures."

    AVERSTAR.  The AverStar bylaws provides that special meetings of
stockholders may be called by the president, a vice-president, the secretary,
chairman of the board of directors, vice-chairman of the board of directors, a
majority of the board of directors or by written request of the holders of a
majority of the outstanding shares of AverStar common stock entitled to vote
(voting together as a single class if more than one class of voting common stock
is outstanding).

STOCKHOLDER ACTION WITHOUT A MEETING

    TITAN.  Titan's bylaws provide that stockholder action may be taken by
written consent instead of a meeting, but only upon compliance with advance
notice and other procedural requirements specified in Titan's bylaws. Any Titan
stockholder of record seeking to have Titan's stockholders authorize or take
corporate action by written consent must, by written notice to Titan's
secretary, request Titan's board of directors to fix a record date for the
purpose of determining the stockholders entitled to consent to the action in
writing without a meeting. Within ten days of receiving the notice, Titan's
board of directors must adopt a resolution fixing the record date, which must
not precede, or be more than ten days after,

                                      102
<PAGE>
the date of the resolution. If the Titan board of directors does not fix a
record date in this manner, the record date:

    - when no prior action by the Titan board of directors is required by
      applicable law, will be the first date on which a signed written consent
      describing the action taken or proposed to be taken is delivered to Titan;
      or

    - when prior action by the Titan board of directors is required by
      applicable law, will be at the close of business on the date on which the
      Titan board of directors adopts the resolution taking the required action.

In addition, Titan's bylaws provide that no stockholder action by written
consent is effective until nationally recognized inspectors of election certify
to Titan that the consents properly delivered to Titan represent at least the
minimum number of votes that would be necessary to take the corporate action.
All stockholder consents must be properly delivered to Titan within 60 days of
the date that the earliest dated written consent was received by Titan.

    AVERSTAR.  The AverStar bylaws permit any action required or permitted at
any meeting of the stockholders to be taken without a meeting, without prior
notice, and without a vote, if one or more written consents describing the
action to be taken are signed by the holders of at least that number of shares
of outstanding stock necessary to approve the matter at a meeting at which the
holders of all shares entitled to vote were present and voted.

STOCKHOLDER PROPOSAL PROCEDURES

    TITAN.  Titan's bylaws require that notice of proposals by stockholders to
be brought before any annual meeting must be delivered to Titan not later than
the 60th day nor earlier than the 90th day before the first anniversary of the
preceding year's annual meeting. If, however, the annual meeting is more than
30 days before or more than 60 days after the anniversary date, the notice must
be delivered not earlier than the 90th day nor later than the 60th day before
the annual meeting, or the 10th day following the date on which Titan first
publicly announces the annual meeting date. The notice must include, as to each
matter the stockholder proposes to bring before the annual meeting:

    - a brief description of the business desired to be brought before the
      annual meeting and the reasons for conducting that business at the annual
      meeting;

    - the name, age and business and residential addresses, as they appear on
      Titan's records, of the stockholders proposing such business;

    - the class and number of Titan's capital stock which are beneficially owned
      by the stockholder; and

    - any material interest of the stockholder in the proposed business.

    AVERSTAR.  The AverStar bylaws do not include any provisions regarding
shareholder proposal procedures.

SHAREHOLDER RIGHTS PLAN

    TITAN.  Titan is a party to the rights agreement with American Stock
Transfer and Trust Company, as rights agent. For information on the rights
agreement, see "Description of Titan Capital Stock--Preferred Share Purchase
Rights."

    AVERSTAR.  AverStar is not a party to any shareholder rights plan.

<PAGE>
CLASSIFIED BOARD OF DIRECTORS

    TITAN.  Titan's certificate of incorporation and bylaws do not provide for a
classified board of directors. The size of Titan's board of directors is
currently fixed by the Titan bylaws at nine directors.

    AVERSTAR.  AverStar's certificate of incorporation and bylaws do not provide
for a classified board of directors. The size of the AverStar board of directors
was initially set by the bylaws at seven and may thereafter be increase or
decreased (but not decreased to less than three directors) as determined by a
majority of the AverStar board of directors or stockholders. The number of
directors of AverStar is currently seven.

NOMINATIONS OF DIRECTORS

    TITAN.  Subject to the rights of holders of Titan's $1.00 cumulative
convertible preferred stock described below, Titan's bylaws provide that
nominations for the election of directors may be made by Titan's board of
directors or Titan's stockholders. Titan's bylaws provide that any stockholder
wishing to nominate persons for election as directors at an annual meeting must
deliver to the secretary of Titan, at Titan's principal office in San Diego, a
written notice of the stockholder's intention to make a director nomination. The
stockholder is required to furnish the notice not later than 60 days nor earlier
than 90 days before the first anniversary of the preceding year's annual
meeting. If, however, the annual meeting is more than 30 days before or more
than 60 days after the anniversary date, the notice must be delivered not
earlier than the 90th day nor later than the 60th day before the annual meeting,
or the 10th day following the date on which Titan first publicly announces the
annual meeting date. The notice must set forth the following information:

    - the name and address of record of the stockholder who intends to make the
      nomination;

    - a representation that the stockholder is a holder of record of Titan
      common stock and intends to appear in person or by proxy at the meeting to
      nominate the person or persons specified in the notice;

    - the name, age, business and residential addresses and principal occupation
      or employment of each nominee;

    - a description of all arrangements or understandings between the
      stockholder and each proposed nominee and any other person or persons,
      naming such person or persons, pursuant to which the nomination or
      nominations are to be made by the stockholder;

    - other information regarding each proposed nominee as would be required to
      be included in a proxy statement filed pursuant to the rules and
      regulations of the SEC; and

    - the written consent of each proposed nominee to serve as a director of
      Titan if so elected.

    Holders of Titan's $1.00 cumulative preferred stock are entitled to elect
two directors to Titan's board of directors in the event of a default in the
payment of dividends on the $1.00 cumulative convertible preferred stock. The
size of Titan's board in this event would be increased by two directors.

    AVERSTAR.  The AverStar bylaws provide that the terms of election and
nomination of directors, other than the initial directors, will be determined in
accordance with AverStar's Stockholders' Agreement. The Stockholders Agreement
provides that AverStar will take all necessary actions to elect and re-elect as
directors of AverStar the following:

    - two nominees designated by Michael B. Alexander (or in the event of
      Mr. Alexander's death or inability to act, the majority of the holders of
      Class A and Class D Voting Common Stock);

    - two nominees designated by Joel N. Levy/Peter M. Shulte, L.L.C.; and

                                      104
<PAGE>
    - three nominees designated by John C. Rennie and/or Sigmund H. Goldblum (or
      in the event of Mr. Rennie's and Mr. Sigmund's death or inability to act,
      the majority of the holders of the Class F Common Stock); provided,
      however that J. Fernando Niebla has the right to designate one of
      Mr. Rennie's and Mr. Goldblum's nominees subject to the reasonable
      approval of the remaining members of AverStar's board of directors.

In addition, the Stockholders Agreement grants various parties the right to
designate certain persons to act as an observer at, and to attend all the
meetings of, the AverStar board of directors, but without the right to vote as a
director at any such meeting.

REMOVAL OF DIRECTORS

    TITAN.  Under Titan's bylaws, Titan's directors may be removed at any time,
either with or without cause, by the affirmative vote of stockholders having a
majority of the voting power of Titan. This bylaw provision is subject to rights
under Titan's certificate of incorporation of holders of Titan's $1.00
cumulative convertible preferred stock during any period in which Titan defaults
on the payment of dividends on the $1.00 cumulative convertible preferred stock.

    AVERSTAR.  The AverStar bylaws provides that any director may be removed,
with or without cause, at any time, by the nominee who elected such director in
accordance with AverStar's Stockholders Agreement.

VACANCIES IN THE BOARD OF DIRECTORS

    TITAN.  Titan's bylaws provide that, when any vacancy occurs in the Titan
board of directors, whether by reason of an increase in the number of members
composing the Titan board of directors, or otherwise, a majority of the
remaining members of the Titan board of directors, even though less than a
quorum may appoint a director or directors to fill such vacancy or vacancies.
The bylaws further provide, however, that if a vacancy is caused by removal,
then the successor must be elected by Titan stockholders at a special meeting
called for that purpose. This bylaw provision is subject to rights under Titan's
certificate of incorporation of holders of Titan's $1.00 cumulative convertible
preferred stock during any period in which Titan defaults on the payment of
dividends on the $1.00 cumulative convertible preferred stock.

    AVERSTAR.  The AverStar bylaws provide that any vacancy in the AverStar
board of directors, arising from the removal of a director or otherwise, may be
filled by the nominee who elected or who has the right to elect such director in
accordance with Averstar's Stockholders Agreement. Any vacancy in the AverStar
board of directors arising by an increase in the number of members composing the
AverStar board of directors may be filled by a majority of the board of
directors, including at least one of the designees of John C. Rennie and/or
Sigmund Goldblum.

INDEMNIFICATION

    TITAN.  Titan's bylaws provide for indemnification by Titan, to the fullest
extent permitted by law, of its officers, directors, employees and agents.

    AVERSTAR.  The AverStar certificate of incorporation provides for
indemnification by AverStar, to the fullest extent permitted by law, of its
officers, directors and any other persons with respect of service to AverStar to
the extent the AverStar board of directors specifies that such persons are
entitled to indemnification.

LIMITATION OF PERSONAL LIABILITY OF DIRECTORS

    TITAN.  Titan's certificate of incorporation provides for the elimination
and limitation of the personal liability of directors for monetary damages to
the fullest extent permitted by the Delaware

                                      105
<PAGE>
General Corporation Law. In addition, Titan's certificate of incorporation
provides that if the Delaware General Corporation Law is amended to authorize
the further elimination or limitation of the liability of a director, then the
liability of the directors will be eliminated or limited to the fullest extent
permitted by the Delaware General Corporation Law, as so amended. The effect of
this provision is to eliminate the rights of Titan and its stockholders, through
stockholder derivative suits on behalf of Titan, to recover monetary damages
against a director for breach of the fiduciary duty of care as a director,
including breaches resulting from negligent or grossly negligent behavior,
except in certain situations. The provision does not limit or eliminate the
rights of Titan or any stockholder to seek non-monetary relief such as an
injunction or rescission upon breach of a director's duty of care. This
provision is consistent with section 102(b)(7) of the Delaware General
Corporation Law, which is designed, among other things, to encourage qualified
individuals to serve as directors of Delaware corporations.

    AVERSTAR.  The AverStar certificate of incorporation eliminates the personal
liability of the AverStar directors to the same extent that the Titan
certificate of incorporation eliminates the personal liability of the Titan
directors.

AMENDMENT OF CERTIFICATE OF INCORPORATION

    TITAN.  Titan's certificate of incorporation may be amended under the
Delaware General Corporation Law by a majority vote of the total number of
shares outstanding and entitled to vote on the amendment. If any amendment of
Titan's certificate of incorporation would adversely affect the rights of any
holders of shares of a class or series of capital stock, or such holders are
entitled to vote on the amendment, the vote of the holders of a majority of all
outstanding shares of the class or series, voting as a class, is also necessary
to authorize the amendment.

    AVERSTAR.  AverStar's certificate of incorporation may be amended under the
Delaware General Corporation Law by a majority vote of the total number of
shares outstanding and entitled to vote on the amendment. The affirmative vote
of at least 85% of the outstanding shares of each voting class, voting
separately as a class, of Class A Common Stock, Class B Common Stock, Class C
Common Stock, Class D Common Stock, Class E Common Stock and, if the interest of
the holders of Class F Common Stock would be adversely affected by such change,
Class F Common Stock would be required to amend or repeal the provisions of the
certificate of incorporation regarding the rights and privileges of AverStar's
common stock or the provisions of the Stockholders' Agreement regarding
nomination and election of directors. If any amendment of AverStar's certificate
of incorporation would adversely affect the rights of any holders of shares of
Non-Voting Class G Common Stock the vote of the holders of at least 85% of all
outstanding shares of Non-Voting Class G Common Stock, voting as a separate
class, is also necessary to authorize the amendment. In addition, any term,
covenant, agreement or condition in the AverStar certificate of amendment
describing the rights of holders of Non-Voting Class G Common Stock may be
amended or compliance thereof may be waived by a written consent signed by the
holders of 66 2/3% or more in interest of the shares of Class G Common Stock
outstanding at any time (excluding all shares owned by AverStar or any of its
affiliates). If any such amendment or waiver will change the number of Class D
Common Stock issuable upon the conversion of any share of Non-Voting Class G
Common Stock or the manner of conversion, such amendment or waiver will also
require the written consent of such affected share of Non-Voting Class G Common
Stock.

AMENDMENT OF BYLAWS

    TITAN.  Titan's bylaws may be amended or repealed either by the Titan board
of directors, acting by the affirmative vote of a majority of the Titan
directors, or by Titan's stockholders.

    AVERSTAR.  AverStar's bylaws may be amended or repealed either by the
AverStar board of directors, acting by the affirmative vote of a majority of the
AverStar directors or by AverStar's stockholders holding a majority of common
stock entitled to vote.

                         REPORT OF INDEPENDENT AUDITORS

Board of Directors and Stockholders
AverStar, Inc.

    We have audited the accompanying consolidated balance sheets of
AverStar, Inc. (the Company) as of December 31, 1999 and 1998, and the related
consolidated statements of operations, changes in redeemable common stock and
stockholders' equity, and cash flows for the years ended December 31, 1999 and
1998 and the ten-month period ended December 31, 1997. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

    We conducted our audits in accordance with auditing standards generally
accepted in the United States. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

    In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
AverStar, Inc. at December 31, 1999 and 1998, and the consolidated results of
its operations and its cash flows for the years ended December 31, 1999 and 1998
and the ten-month period ended December 31, 1997, in conformity with accounting
principles generally accepted in the United States.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                               DECEMBER 31, 1999

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND BASIS OF PRESENTATION

NATURE OF OPERATIONS

    AverStar, Inc. (AverStar or the Company) provides information technology, or
IT, services and software products for the mission-critical systems of civilian
and defense agencies of the United States government, as well as large
commercial companies.

BASIS OF PRESENTATION

    These consolidated financial statements include the accounts of AverStar and
its wholly-owned subsidiary, Computer Based Systems, Inc. (CBSI). The Company
was incorporated in Delaware on February 4, 1998 for the purpose of combining
the businesses of Apollo Holdings, Inc. (Apollo) and Pacer Infotec, Inc.
(Pacer). All material intercompany balances and transactions have been
eliminated.

    Prior to February 4, 1998, the Company operated as Apollo, and the financial
statements included herein reflect the operations of Apollo for those periods
presented. On February 4, 1998, the Company was formed by the Apollo
shareholders to acquire the business of Pacer (see Note 2) and to combine the
businesses of Apollo and Pacer. In connection with these activities, the Company
effected exchanges of stock with both Apollo and Pacer shareholders at the time
of the acquisition of Pacer. As described in Note 2, the acquisition of Pacer
has been accounted for as a purchase. The exchange by Apollo shareholders of
their shares in Apollo for their shares in AverStar was accounted for as an
exchange of shares by entities under common control in accordance with
paragraph 5 of APB No. 16. Accordingly, the Apollo operations retained their
historical cost basis. All share and per share data in these financial
statements and related footnotes have been adjusted to reflect such exchanges.

    In 1997, the Board of Directors changed Apollo's fiscal year from the last
day of February to the last day of December. For the year ended December 31,
1999, the financial statements include twelve months of operations for AverStar
and approximately nine months of operations of CBSI. For the year ended
December 31, 1998, the financial statements include twelve months of operations
for Apollo and approximately ten months of operations for Pacer. For the period
ended December 31, 1997, the financial statements include ten months of
operations for Apollo.

Federal Government. These contracts provide for periodic payments as the
services are performed and generally do not represent any unusual burden on the
Company's liquidity. All contracts with the Federal Government are subject to
termination by the customer. The Company has not suffered any adverse effects
from the termination of Government contracts in the past.

    The Company recognizes revenue on government and commercial contracts under
the percentage-of-completion method in accordance with Statement of Position
81-1, "Accounting for Performance of Construction-Type and Certain
Production-Type Contracts." The percentage of completion is determined by
relating the costs incurred to date to the estimated total costs at completion.

revenues are recorded in the period in which the facts requiring revision become
known. When a loss is anticipated on a contract, the full amount of the
anticipated loss is provided for when it becomes probable. The Company sometimes
recognizes revenue that is not billable to the customer at a given balance sheet
date. Such amounts are included in unbilled receivables.

    Revenues from standard software products are recognized upon shipment in
accordance with Statement of Position 97-2, "Software Revenue Recognition," as
amended by the Statement of Position 98-4. Revenues from maintenance agreements
are recognized over the life of the maintenance agreement. Per unit royalties
earned from the license of standard software products are recognized when
received from the customer.

CASH EQUIVALENTS

    The Company considers all highly liquid investments purchased with a
maturity of three months or less to be cash equivalents.

UNBILLED ACCOUNTS RECEIVABLE

    Unbilled accounts receivable represent amounts earned on contracts in
process and retainage that are not billable at the balance sheet date. Such
amounts generally become billable upon completion of a specific phase of the
contract, documentation of approved contract modifications, completion of
government audit or upon customer acceptance, if the Company believes the
acceptance criteria present no risk to the Company. The Company has not
recognized significant revenue relating to customer claims for amounts in excess
of agreed-upon contract prices. To the extent billings exceed costs incurred,
plus fees or less losses, the difference is recorded as unearned revenue.

PROPERTY, PLANT AND EQUIPMENT

    Property, plant and equipment are stated at cost. The Company provides for
depreciation and amortization over estimated useful lives using the
straight-line method as follows:

STOCK COMPENSATION

    The Company accounts for grants of stock options in accordance with the

The Company has adopted the disclosure-only provision of Statement of Financial
Accounting Standards No. 123, "Accounting for Stock-Based Compensation." (See

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND BASIS OF PRESENTATION
(CONTINUED)
USE OF ESTIMATES

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

IMPAIRMENT EVALUATION

    The Company examines the carrying value of its long-lived assets,
identifiable intangibles and goodwill to determine whether there are any
impairment losses. If indicators of impairment were present in those assets, and
future undiscounted cash flows were not expected to be sufficient to recover the
assets' carrying amounts, an impairment loss would be charged to expense in the
period identified. No event has been identified that would indicate an
impairment of the value of long-lived assets, identifiable intangibles and
goodwill recorded in the accompanying consolidated financial statements.

CONCENTRATIONS OF CREDIT RISK

    Financial instruments that subject the Company to credit risk consist of
cash equivalents and accounts receivable. The risk with respect to cash
equivalents is minimized by the Company's policies in which investments are
placed with highly rated issuers with relatively short maturities. The risk with
respect to accounts receivable is minimized due to the fact that customer
accounts and unbilled receivables represent amounts earned under the Company's
contracts, which are principally with U.S. Government agencies.

FAIR VALUE OF FINANCIAL INSTRUMENTS

    The Company's cash equivalents, accounts receivable, long-term debt and
redeemable common stock are carried at cost, which approximates fair value.

RECLASSIFICATIONS

    Certain reclassifications have been made to the 1998 financial statements to
conform to the 1999 basis of presentation.

SEGMENTS OF AN ENTERPRISE

    The Company has one reportable segment from continuing operations: the
development and delivery of information technology products and services. The
U.S. Government and its prime aerospace, civil and defense contractors accounted
for approximately 90%, 90% and 80% of the Company's revenues for the years ended
December 31, 1999 and 1998 and the ten-month period ended December 31, 1997,
respectively.

PENDING ACCOUNTING PRONOUNCEMENTS

    In June 1998, the Financial Accounting Standards Board issued Statement
No. 133 (FAS 133), "Accounting for Derivative Investments and Hedging
Activities," which required adoption for fiscal years beginning after June 15,
1999. FAS 133 was subsequently amended by Statement of Financial Accounting
Standards No. 137, "Accounting for Derivative Instruments and Hedging
Activities--Deferral of the Effective Date of FASB Statement No. 133," and now
will be effective for fiscal years beginning after June 15, 2000, with earlier
adoption permitted. The adoption of FAS 133 is not expected to have a material
impact on the results of operations or financial position of the Company.

    In December 1999, the Securities Exchange Commission issued Staff Accounting
Bulletin 101 (SAB 101), "Revenue Recognition in Financial Statements." SAB 101
summarizes the application of generally accepted accounting principles to
revenue recognition in financial statements. On March 24, 2000, the SEC issued
an Amendment to SAB 101 (SAB 101A), delaying the effective date for certain
companies. The Company will adopt SAB 101 in the second quarter of fiscal 2000
and is presently analyzing what impact, if any, SAB 101 will have on the results
of operations or financial position of the Company.

2. ACQUISITIONS

    On February 27, 1998, Pacer, a company providing software-engineering
services primarily to government customers, was acquired for a purchase price of
approximately $17,000,000, plus transaction-related expenses of approximately
$1,700,000. Of the total purchase price, approximately $7,000,000 was paid in
cash to Pacer shareholders. The balance was paid by the issuance of
approximately 2,255,000 shares of Class F common stock issued by AverStar and
the fair value of options exchanged in the transaction; said shares and options
having a value of approximately $10,000,000. The acquisition has been accounted
for using the purchase method of accounting, whereby assets and liabilities have
been allocated based upon their respective fair values, resulting in goodwill
and other intangible assets of approximately $12 million, which will be
amortized for periods not to exceed 20 years.

    On March 18, 1999, the Company acquired all of the outstanding shares of
Computer Based Systems, Inc. (CBSI) for $26,000,000, plus transaction related
expenses of $261,000. CBSI provides IT network operations services primarily to
government customers. Of the total purchase price, $25,000,000 was paid to the
shareholders at the closing, with the balance paid equally over five years. The
acquisition was accounted for using the purchase method of accounting, whereby
assets and liabilities have been allocated based upon their respective fair
value, resulting in goodwill and other intangibles assets of approximately
$19,100,000, which will be amortized for periods not to exceed 20 years.

3. DISCONTINUED OPERATIONS

    In December 1998, the Board of Directors of AverStar, Inc. adopted a plan to
divest of its 66% interest in Intermetrics Entertainment Software, Inc.'s (IES)
operations, which developed software games, by distributing such interest to
AverStar shareholders.

    As part of the plan to dispose of IES, the Company converted $1.3 million of
contributed capital (representing capital contributed by the Company reduced by
cumulative operating losses) into an 8.5% term loan due on December 31, 2001. In
connection with this conversion, the Company recorded the term loan and fully
reserved the amount and also fully reserved a pre-existing term loan of $400,000
because, based upon forecasted operating results for IES, the Company believed
it was uncollectible. This write-off is part of the loss on disposal of
discontinued operations described below. In addition, the Company was obligated
to provide on demand financing of up to $2 million pursuant to an 8.5% revolving
credit agreement, unless IES filed for bankruptcy, is in the process of
liquidation or the equivalent. Under the terms of the revolving credit
agreement, no new borrowings may occur subsequent to December 31, 1999 and
amounts borrowed are due on December 31, 2001. As of December 31, 1999, the
Company funded the revolving credit agreement up to the maximum $2 million.
Management does not believe such amount will be recoverable and, therefore, has
assigned no value to it in the accompanying consolidated financial statements.
The Company is, however, pursuing collection efforts. Any subsequent recovery of
such amounts due under the term loans or the revolving credit agreement, all of
which are due not later than December 31, 2001, and currently represent a
deferred gain of $3,700,000, will be reflected as a gain from discontinued
operations at the time of such recovery.

    The major components of the $3,900,000 loss on disposal of discontinued
operations in 1998 are estimated operating losses through the disposal date of
$500,000, estimated remaining funding commitment of $1,500,000 pursuant to a
$2,000,000 revolving credit agreement, estimated professional fees of $200,000
and write-offs of estimated non-recoverable term loans of $1,700,000.

    As of December 31, 1998, the liabilities of IES exceeded its assets by
$565,000, which comprised billed and unbilled accounts receivable of $4,200,000,
other assets and equipment of $2,300,000, bank debt of $3,900,000, accrued
expenses of $1,500,000 and obligations to AverStar of approximately $1,700,000.
Included in the loss on disposal in 1998 is approximately $500,000 of operating
losses from the date the plan was adopted through the date of divestiture, which
occurred on March 18, 1999.

3. DISCONTINUED OPERATIONS (CONTINUED)
    In addition, interest of $293,000 was allocated to the loss from
discontinued operations based on the financing that was specifically attributed
to those operations.

    Revenues from discontinued operations were $1,516,000 for the period from
January 1, 1999 through March 18, 1999, $7,232,000 for the year ended
December 31, 1998 and $1,928,000 for the period from August 9, 1997 through
December 31, 1997. Losses from operations for these periods were approximately
$715,000, $3,895,000 and $1,802,000, respectively.

6. BENEFIT PLANS

    The Company has a 401(k) Profit Sharing and Savings Plan (the Plan) that
covers substantially all employees and provides for a Company matching
contribution. As defined under the Plan, employees are allowed to contribute the
maximum established by law, and the Company may match 50% of an employee's
contribution, up to 4% of an employee's eligible compensation. Expenses relating
to the Plan amounted to $1,771,000 and $1,405,000 for the years ended
December 31, 1999 and 1998 and $784,000 for the ten-month period ended
December 31, 1997. In 1999, $120,000 of forfeitures from unvested benefits of
terminated employees were used to reduce the expenses of the Plan.

    In connection with the merger of Apollo and Pacer (as described in Note 2),
the Apollo stockholders agreed to exchange their shares of Class A, B, C, D, E
and G into shares of AverStar at a ratio of approximately 4.6:1. Pacer
stockholders were given the choice of receiving $2.00 per share in cash or
exchanging their shares of Pacer into Class F shares of AverStar at a ratio of
approximately 0.5:1. Such issuance and exchanges are reflected in the table.

    Certain classes of common stock have provisions which require the holders,
in certain circumstances, to share a portion of proceeds received upon the sale
of such shares with holders of other classes of common stock.

9. REDEEMABLE COMMON STOCK

    In connection with the Pacer acquisition (as described in Note 2), the
Company granted certain shareholders rights that require the Company to purchase
up to a maximum number of shares of Class F--voting common stock held by the
shareholders at $4.09 per share over a four-year period. Shares that are not
redeemed in a year convert to shareholders' equity and the shareholders' rights
to redeem these shares expire. The 1999 activity and schedule of
Class F--voting redeemable shares are as follows:

    Certain Class F--voting, redeemable shares serve as collateral on a note
receivable of approximately $850,000 issued to the Company by a former employee.
The note bears interest at 6.36% per annum with scheduled repayments through
May 2001. In the event the Class F shareholder presents certain shares to the
Company for redemption, the proceeds from such redemption are required to be
remitted to the Company in satisfaction of this note, which is included in other
assets in the accompanying consolidated balance sheet.

    In addition to the redemption features of the Class F--voting shares, the
Company has also granted to certain management shareholders the right to have
the Company redeem shares of Class A-F stock at certain amounts, as defined. As
of December 31, 1999, management shareholders held approximately 1,526,000
shares with an estimated redemption of fair value of $3,429,000. The redemption
of such shares is limited in the first five years by amounts stipulated in the
Stockholder Agreements. Upon the occurrence of certain events, including an
initial public offering, the redemption features for all classes of stock lapse.

    The Company holds promissory notes of $200,000 issued by certain employees
for the purchase of Class A common stock. The promissory notes, which are fully
recourse to the issuers and have been classified as a reduction of redeemable
common stock, bear interest at 7% per annum. Interest is payable semiannually or
annually, and the principal is scheduled for payment from March 2000 through
August 2005.

10. STOCK OPTIONS

    The Company has a Long-Term Incentive Plan (the Plan) pursuant to which the
Company may grant Incentive Stock Options, Non-qualified Stock Options, Stock
Appreciation Rights, Restricted Stock, Deferred Stock, Stock Purchase Rights or
Other Stock-Based Awards. The maximum aggregate number of shares of stock
reserved and available for distribution under the Plan shall be 3,349,447,
reduced by the number of shares of stock subject to being issued from time to
time upon the exercise of outstanding awards granted under the Plan. At
December 31, 1999, there were 1,779,834 shares of stock reserved and available
for distribution.

    The Company has adopted the disclosure-only provisions of Statement of
Financial Accounting Standards (SFAS) No. 123, "Accounting for Stock-Based
Compensation," and will continue to account for option grants to employees under
the Plan in accordance with APB No. 25, "Accounting for Stock Issued to
Employees." Adoption of SFAS No. 123 did not have a material impact on the
Company's financial statements and, accordingly, no pro forma net income has
been disclosed for the years ended December 31, 1999 and 1998 and the ten-month
period ended December 31, 1997 for the

               CONVERSION OF SECURITIES; EXCHANGE OF CERTIFICATES

SECTION 2.01 THE MERGER

    At the Effective Time, by virtue of the Merger and without any action on the
part of Acquiror, Acquiror Sub, the Company or the holders of any of the
securities referred to in this Section 2.01:

    (a)  COMMON STOCK.  Subject to Section 2.06, (i) each share of Company
Common Stock (excluding any shares described in Section 2.01(c) and (f)) issued
and outstanding immediately prior to the Effective Time shall cease to be
outstanding and shall be converted into and exchanged for the right to receive a
portion of a share of common stock, par value $0.01, of Acquiror ("Acquiror
Common Stock") equal to the Exchange Ratio (as defined below). The shares of
Acquiror Common Stock issuable to the holders of Company Common Stock pursuant
hereto is sometimes referred to herein, collectively, as the "Merger
Consideration". All such shares of Company Common Stock shall cease to be
outstanding and shall automatically be canceled and retired and shall cease to
exist, and each certificate previously evidencing any such shares shall
thereafter represent only the right to receive the Merger Consideration. Except
as otherwise provided herein or by applicable law, the holders of certificates
previously evidencing such shares of Company Common Stock outstanding
immediately prior to the Effective Time shall cease to have any rights with
respect to such shares of Company Common Stock. Each such certificate previously
evidencing such shares of Company Common Stock shall be exchanged for the number
of shares indicated in the certificate provided by the Company pursuant to
Section 6.08 in accordance with the provisions of Section 2.02 multiplied by the
Exchange Ratio, rounded up to the nearest whole number.

    The "Exchange Ratio" shall be determined as follows:

        (i) if the Acquiror Stock Price is less than or equal to $56.00 per
    share and greater than or equal to $44.00 per share, the Exchange Ratio
    shall be equal to the quotient obtained by dividing the Company Stock Value
    by the Acquiror Stock Price;

        (ii) if the Acquiror Stock Price is less than $44.00 per share and
    greater than or equal to $39.60 per share, the Exchange Ratio shall be equal
    to the quotient obtained by dividing the Company Stock Value by $44.00;

       (iii) if the Acquiror Stock Price is greater than $56.00 per share and
    less than or equal to $61.60 per share, the Exchange Ratio shall be equal to
    the quotient obtained by dividing the Company Stock Value by $56.00;

        (iv) if the Acquiror Stock Price is greater than $61.60 per share,
    (A) Acquiror may terminate this Merger Agreement pursuant to
    Section 8.01(d)(i), unless the Company makes a "Company Floating Rate
    Election" prior to the Scheduled Closing Date, in which case the Exchange
    Ratio shall be equal to the quotient obtained by dividing (x) the product of
    the Company Stock Value multiplied by 1.10 by (y) the Acquiror Stock Price
    or (B) in the event that Acquiror does not terminate this Agreement pursuant
    to clause (A) and the Company does not make a Company Floating Rate
    Election, the Exchange Ratio shall be equal to the quotient obtained by
    dividing the Company Stock Value by $56.00;

        (v) if the Acquiror Stock Price is less than $39.60 per share,
    (A) Company may terminate this Merger Agreement pursuant to
    Section 8.01(d)(ii), unless the Acquiror makes an "Acquiror Floating Rate
    Election" prior to the Scheduled Closing Date, in which case the Exchange
    Ratio shall be equal to the quotient obtained by dividing (x) the product of
    the Company Stock Value multiplied by 0.90 by (y) the Acquiror Stock Price
    or (B) in the event that Company does not terminate this Agreement pursuant
    to clause (A) and Acquiror does not make the Acquiror

                                      A-3
<PAGE>
    Floating Rate Election, the Exchange Ratio shall be equal to the quotient
    obtained by dividing the Company Stock Value by $44.00.

    (b)  CERTAIN DEFINITIONS.  For purposes of this Merger Agreement, (i) the
term "Acquiror Stock Price" shall mean the average of the closing sale prices of
a share of Acquiror Common Stock as reported on the New York Stock Exchange
("NYSE") for the ten (10) consecutive trading days ending with and including the
second trading day immediately preceding the date of the Scheduled Closing Date;
(ii) the term "Acquiror Floating Rate Election" shall mean an election made by
Acquiror to use the Exchange Ratio calculated pursuant to
Section 2.01(a)(v)(A); and (iii) the term "Company Floating Rate Election" shall
mean an election made by the Company to use the Exchange Ratio calculated
pursuant to Section 2.01(a)(iv)(A).

    (c)  TREASURY STOCK.  All shares of capital stock of the Company held in the
treasury of the Company immediately prior to the Effective Time shall be
canceled and extinguished without any conversion thereof and no amount shall be
delivered or deliverable in exchange therefor.

    (d)  ACQUIROR SUB STOCK.  Each share of common stock, par value $.01 per
share, of Acquiror Sub issued and outstanding immediately prior to the Effective
Time ("Acquiror Sub Stock") shall be converted into and exchanged for one
(1) duly and validly issued, fully paid and nonassessable share of common stock
of the Surviving Corporation.

    (e)  [Intentionally Omitted].

    (f)  DISSENTING SHARES.  Notwithstanding anything in this Merger Agreement
to the contrary and unless otherwise provided by applicable law, shares of
Company Common Stock that are issued and outstanding immediately prior to the
Effective Time and that are owned by Company Stockholders who have properly
demanded payment of the fair value of their stock (the "Dissenting Shares")
within the meaning of Section 262 of Delaware Law shall not be converted into
the right to receive the Merger Consideration unless and until such Company
Stockholders shall have failed to perfect or shall have effectively withdrawn
their demand, or lost their right of payment under applicable law. If any such
Company Stockholder shall have failed to perfect or shall have effectively
withdrawn or lost such right of payment, each share of Company Common Stock held
by such Company Stockholder shall thereupon be deemed converted into the right
to receive and exchangeable for, at the Effective Time, the Merger Consideration
pursuant to Section 2.02 of this Merger Agreement. Subject to the terms and
conditions of this Merger Agreement, at and after the Effective Time, any holder
of shares of Company Common Stock who complies with Section 262 of Delaware Law
(a "Company Dissenting Stockholder") shall be entitled to obtain payment from
Surviving Corporation of the fair value of such Company Dissenting Stockholder's
shares of Company Common Stock as determined pursuant to Delaware Law; PROVIDED,
HOWEVER, that, to the extent permissible under Delaware Law, no such payment
shall be made unless and until such Company Dissenting Stockholder has
surrendered to the Exchange Agent the Certificate representing the shares of
Company Common Stock for which payment is being made.

    (g)  PROCEDURE WITH RESPECT TO DISSENTING SHARES.  Company shall give
Acquiror (i) prompt notice of any written notice of intent to demand payment for
shares filed pursuant to Section 262 of Delaware Law received by Company,
withdrawals of such notices, and any other instruments served in connection with
such notices pursuant to the relevant provisions of Delaware Law and received by
Company and (ii) the opportunity to direct all negotiations and proceedings with
respect to such notices under Delaware Law consistent with the obligations of
Company thereunder. Company shall not, except with the prior written consent of
Acquiror (which shall not be unreasonably withheld), (A) make any payment with
respect to any such notice, (B) offer to settle or settle any such notices or
(C) waive any failure to timely deliver a written notice in accordance with the
Delaware Law.

                                      A-4
<PAGE>
    (h)  FLOATING RATE ELECTION.  The Company and the Acquiror shall deliver the
Company Floating Rate Election or the Acquiror Floating Rate Election, as the
case may be, by notice to the other Party prior to the Scheduled Closing Date.
The Company Floating Rate Election and the Acquiror Floating Rate Election may
be delivered notwithstanding the fact that the other Party has not then elected
to terminate this Merger Agreement pursuant to Section 2.01(a) and
Section 8.01(d), in which event the other Party shall not be entitled to
terminate this Merger Agreement pursuant to Section 2.01(a) or Section 8.01(d).

SECTION 2.02 EXCHANGE OF CERTIFICATES

    (a)  EXCHANGE AGENT.  As soon as reasonably practicable after the Effective
Time, but in no event later than four (4) business days after the Effective Time
(assuming the Company has provided to Acquiror an electronic list of the names,
addresses, and tax identification numbers of the Company Stockholders and the
information provided in the certificate in Section 6.08 at least one
(1) business day prior to the Effective Time), Acquiror shall deposit with an
exchange agent designated by Acquiror and reasonably acceptable to Company (the
"Exchange Agent") pursuant to an exchange agreement in the form attached hereto
as Exhibit C, for the benefit of the former holders of shares of Company Common
Stock (excluding any shares described in Section 2.01(c)), for issuance and
payment in accordance with this Article II the shares of Acquiror Common Stock
(but not including the Escrow Stock) issuable pursuant to Section 2.01(a) (such
shares of Acquiror Common Stock being hereinafter referred to as the "Exchange
Fund"). Acquiror shall cause the Exchange Agent, pursuant to irrevocable
instructions, to deliver Acquiror Common Stock contemplated to be delivered
pursuant to Section 2.01(a) out of the Exchange Fund within three (3) business
days of the Exchange Agent's receipt of all information and documentation
required pursuant to Section 2.02(b). The Exchange Fund shall not be used for
any purpose other than as set forth in this Section 2.02(a).

    (b)  PAYMENT PROCEDURES.  As soon as reasonably practicable after the
Effective Time, but in no event later than four (4) business days after the
Effective Time (assuming the Company has provided to Acquiror an electronic list
of the names, addresses, and tax identification numbers of the Company
Stockholders and the information provided in the certificate in Section 6.08 at
least one (1) business day prior to the Effective Time), Acquiror shall cause
the Exchange Agent to mail to each record holder, as of the Effective Time, of
an outstanding certificate or certificates (each a "Certificate" and
collectively, the "Certificates") that immediately prior to the Effective Time
evidenced outstanding shares of Company Common Stock (excluding any shares
described in Sections 2.01(c)): (i) a form letter of transmittal and
(ii) instructions for use in effecting the surrender of the Certificates for
payment therefor. The Exchange Agent shall provide to the Company (for delivery
to the Company Stockholders) all such documentation in advance of the Effective
Time, but in any event not less than one (1) week prior to the Closing Date.
Upon surrender to the Exchange Agent of a Certificate, together with such letter
of transmittal duly executed and any other required documents, the holder of
such Certificate shall be entitled to receive in exchange therefor the
applicable consideration set forth in Section 2.01, and such Certificate shall
forthwith be canceled. In the event of a surrender of a Certificate representing
shares of Company Common Stock which are not registered in the transfer records
of the Company under the name of the Person surrendering such Certificate, a
certificate representing the proper number of shares of Acquiror Common Stock
may be issued to a Person other than the Person in whose name the Certificate so
surrendered is registered if (x) such Certificate shall be properly endorsed or
otherwise be in proper form for transfer to the Person surrendering such
Certificate and requesting such issuance, (y) such Person surrendering such
Certificate and requesting such issuance shall pay any transfer or other Taxes
required by reason of the issuance of shares of Acquiror Common Stock to a
Person other than the registered holder of such Certificate or shall establish
to the satisfaction of Acquiror that such Taxes have been paid or are not
applicable, and (z) such Person surrendering such certificate shall, if required
by Acquiror, have such Person's signature

                                      A-5
<PAGE>
guaranteed by a bank, brokerage firm or other financial intermediary that is a
member of a medallion guarantee program. Until surrendered in accordance with
the provisions of this Section 2.02, each Certificate shall represent for all
purposes only the right to receive the applicable consideration set forth in
Section 2.01, without any interest thereon.

    (c)  ISSUANCES TO AFFILIATES.  Notwithstanding anything herein to the
contrary, any Certificate surrendered for exchange by any "affiliate" of the
Company (as that term is used in SEC Accounting Series Release Nos. 130 and 135
and Rule 145 of the rules and regulations of the SEC under the Securities Act)
shall not be exchanged until Acquiror shall have received a signed agreement
from such "affiliate" as provided in Section 5.12 hereof.

    (d)  NO FURTHER RIGHTS IN STOCK.  All shares of Acquiror Common Stock issued
upon the surrender for exchange of Certificates in accordance with the terms of
Sections 2.01 and 2.02 hereof shall be deemed to have been issued in full
satisfaction of all rights pertaining to the shares of Company Common Stock
theretofore represented by such Certificates, and there shall be no further
registration of transfer on the stock transfer books of the Surviving
Corporation of the shares of Company Common Stock represented by such
Certificates which were outstanding immediately prior to the Effective Time. If,
after the Effective Time, any such Certificates are presented to Acquiror, the
Surviving Corporation or the Exchange Agent for any reason, they shall be
canceled and exchanged as provided in this Article II, except as otherwise
provided by law.

    (e)  [Intentionally Omitted]

    (f)  TERMINATION OF EXCHANGE FUND.  Any portion of the Exchange Fund that
remains undistributed to the holders of Company Common Stock for twelve
(12) months after the Effective Time shall be delivered to Acquiror, upon
demand, and any holder of Company Common Stock that has not theretofore complied
with this Article II shall thereafter look only to the Surviving Corporation and
Acquiror for the Merger Consideration to which such holder is entitled pursuant
hereto.

    (g)  NO LIABILITY.  Neither Acquiror nor the Surviving Corporation shall be
liable to any holder of shares of Company Common Stock for any Acquiror Common
Stock or cash delivered to a public official pursuant to any applicable
abandoned property, escheat or similar law.

    (h)  WITHHOLDING OF TAX.  Acquiror or the Exchange Agent shall be entitled
to deduct and withhold from the applicable amount of the Merger Consideration
otherwise issuable to any former holder of Company Common Stock such amounts as
Acquiror (or any Affiliate thereof) or the Exchange Agent are required to deduct
and withhold with respect to the making of such payment under the Code, or any
provision of state, local or foreign Tax law. To the extent that amounts are so
withheld by Acquiror (or any Affiliate thereof) or the Exchange Agent, such
withheld amounts shall be treated for all purposes of this Merger Agreement as
having been paid to the former holder of Company Common Stock in respect of whom
such deduction and withholding was made by Acquiror (or any Affiliate thereof)
or the Exchange Agent.

    (i)  LOST, STOLEN OR DESTROYED CERTIFICATES.  In the event any Certificate
evidencing shares of Company Common Stock shall have been lost, stolen or
destroyed, upon the making of an affidavit setting forth that fact by the Person
claiming such lost, stolen or destroyed Certificate and the granting of a
reasonable indemnity against any claim that may be made against Acquiror or the
Exchange Agent with respect to such Certificate (and if required by Acquiror in
the case of any Certificate or Certificates from any Company Stockholder
representing more than seven thousand five hundred (7,500) shares of Company
Common Stock, the posting by such Person of a bond, in such reasonable amount as
Acquiror may direct), Acquiror shall cause the Exchange Agent to pay to such
Person the applicable amount of the Merger Consideration with respect to such
lost, stolen or destroyed Certificate.

                                      A-6
<PAGE>
    (j)  DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED SHARES OF ACQUIROR COMMON
STOCK.  No dividends or other distributions declared or made after the Effective
Time with respect to Acquiror Common Stock with a record date after the
Effective Time shall be paid to the holder of any unsurrendered Certificate with
respect to the shares of Acquiror Common Stock evidenced thereby until the
holder of such Certificate shall properly surrender such Certificate in
accordance with the requirements of Section 2.02(b). Subject to the effect of
escheat, tax or other applicable laws, following surrender of any such
Certificate, there shall be paid to the holder of the certificates evidencing
whole shares of Acquiror Common Stock issued in exchange therefor, without
interest, (i) promptly the amount of dividends or other distributions with a
record date after the Effective Time and theretofore paid with respect to such
whole shares of Acquiror Common Stock, and (ii) at the appropriate payment date,
the amount of dividends or other distributions, with a record date after the
Effective Time but prior to surrender and a payment date occurring after
surrender, payable with respect to such whole shares of Acquiror Common Stock.

    (k)  APPOINTMENT OF STOCKHOLDERS' REPRESENTATIVES.  Michael B. Alexander,
Sigmund H. Goldblum and Peter Schulte shall, by virtue of the Merger, be
appointed attorneys-in-fact and authorized and empowered to act, for and on
behalf of any or all of the Company Stockholders (with full power of
substitution in the premises), in connection with the provisions of Article IX
as they relate to the Company and the Company Stockholders generally, and such
other matters as are reasonably necessary for the consummation of the
transactions contemplated hereby including, without limitation, (i) to

(ii) to execute and deliver on behalf of the Company Stockholders any documents
or agreements contemplated by or necessary or desirable in connection with this
Merger Agreement and (iii) to take such further actions including coordinating
and administering post-closing matters related to the rights and obligations of
the Company Stockholders as are authorized in this Merger Agreement (the above
named representatives, as well as any subsequent representative(s) of the
Company Stockholders appointed by the Company Stockholders being referred to
herein as the "Stockholders' Representatives"). The Stockholders'
Representatives shall not be liable to any Company Stockholder, Acquiror, the
Surviving Corporation or their respective Affiliates or any other Person with
respect to any action taken or omitted to be taken by the any of Stockholders'
Representatives in their role as Stockholders' Representatives under or in
connection with this Merger Agreement unless such action or omission results

on the part of the Stockholders' Representatives. Acquiror, Acquiror Sub and the
Surviving Corporation shall be entitled to rely on such appointment and treat
such Stockholders' Representatives, or any one of them, as the duly appointed
attorney-in-fact of each Company Stockholder. Each Company Stockholder who votes
in favor of the Merger pursuant to the terms hereof, by such vote and without

Consideration in connection with the Merger, by acceptance thereof and without

Acquiror receives conflicting instructions from different Stockholders'
Representatives, Acquiror shall be permitted to take no action with respect

Representatives or directed by court order.

SECTION 2.03 STOCK OPTIONS

    (a) As of the Effective Time, each outstanding Option shall be converted
into an option to acquire Acquiror Common Stock as provided in this
Section 2.03. Following the Effective Time, each Option shall continue to have,
and shall be subject to, the terms and conditions of each agreement pursuant to
which such Option was subject immediately prior to the Effective Time
(including, in the case of each Option granted under the Company's 1998 Long
Term Incentive Plan, the terms and conditions of the Company's 1998 Long Term
Incentive Plan under which such Option was granted), except that: (i) each
Option (as converted pursuant to this Section 2.03) shall be exercisable for
that number of whole shares of Acquiror Common Stock equal to the product of
(A) the aggregate number

                                      A-7
<PAGE>
of shares of Company Common Stock for which such Option was exercisable at the
Effective Time, multiplied by (B) the Exchange Ratio, rounded up to the nearest
whole share (provided that all references in such Company Stock Option Plans and
the agreement under which such Option was granted to the Company shall be
references to Acquiror and references to the Company's Common Stock shall be
references to Acquiror Common Stock); and (ii) the exercise price per share of
Acquiror Common Stock issuable pursuant to each Option (as converted pursuant to
this Section 2.03) shall be equal to the exercise price per share of Company
Common Stock under such Option at the Effective Time divided by the Exchange
Ratio, rounded to the nearest whole cent.

    (b) The assumption and substitution of Options as provided herein shall not
give the holders of such Options additional benefits or additional (or
accelerated) vesting rights that they did not have immediately prior to the
Effective Time or relieve the holders of such Options from any obligations or
restrictions applicable to their Options or the shares obtainable upon exercise
of the Options. The adjustment provided herein with respect to any Options that
are "incentive stock options" (as defined in Section 422 of the Code) shall be
and is intended to be, effected in a manner that is consistent with continued
treatment of such Options as "incentive stock options" under Section 424(a) of
the Code. The duration and other terms of the converted options provided for in
this Section 2.03 shall be the same as the Options except that all references to
the Company shall be references to Acquiror and references to the Company's
Common Stock shall be references to Acquiror Common Stock. Acquiror shall take
all corporate action necessary to reserve for issuance, at all times any
converted Options provided for in this Section 2.03 are outstanding, a
sufficient number of shares of Acquiror Common Stock for delivery upon the
exercise of such converted Options. The Company will take such action as shall
be reasonably necessary (including but not limited to obtaining waivers from
holders of Options) so that each Option that was unvested or subject to a
repurchase option, risk of forfeiture or other condition under any applicable
Company Stock Option Plans immediately prior to the Effective Time shall
continue to be subject to such vesting, repurchase, forfeiture or other
conditions with respect to the Acquiror Common Stock that may be issuable with
respect thereto after the occurrence of the Effective Time or the consummation
of the transactions contemplated by this Merger Agreement. As of the Effective
Time, the Company shall effect the termination of each other outstanding
unexpired and unexercised option to purchase shares of Company Common Stock.

SECTION 2.04 CERTAIN ADJUSTMENTS

    If between the date hereof and the Effective Time, the outstanding shares of
Company Common Stock or of Acquiror Common Stock shall be changed into a
different number of shares by reason of any reclassification, recapitalization,
split-up, combination or exchange of shares, or any dividend payable in stock or
other securities shall be declared thereon with a record date within such
period, the Exchange Ratio (and any other references herein to a price per share
of Acquiror Common Stock) shall be adjusted accordingly to provide the same
economic effect as contemplated by this Merger Agreement prior to such
reclassification, recapitalization, split-up, combination, exchange or dividend.

SECTION 2.05 CLOSING

    Subject to the terms and conditions of this Merger Agreement, the closing of
the Merger (the "Closing" and the date of such Closing, the "Scheduled Closing

SECTION 2.06 ESCROW STOCK; DETERMINATION OF CLOSING ADJUSTMENT

    (a)  ESCROW STOCK.  When making the issuances of Acquiror Common Stock
pursuant to Section 2.01(a) above, Acquiror shall withhold from the Company
Stockholders a number of shares of Acquiror Common Stock equal to the quotient
of five percent (5%) of the Transaction Value divided by the Acquiror Stock
Price (the "Escrow Stock"). The Escrow Stock will be placed in escrow as
security for the performance of the indemnity obligations of the Company
Stockholders under Section 9.02 of this Merger Agreement and to pay Acquiror any
Closing Adjustment required to be paid to Acquiror pursuant to this
Section 2.06, all pursuant to the terms and conditions of an escrow agreement
among Acquiror, the Surviving Corporation, the Stockholders' Representatives and
First Union National Bank or another escrow agent designated by Acquiror and
reasonably acceptable to the Company (the "Escrow Agent"), in form attached
hereto as Exhibit D (the "Escrow Agreement"). The Escrow Stock shall be
registered in the name of the Escrow Agent as nominee for the Company
Stockholders. The Merger Consideration otherwise distributable as of the
Effective Time to each Company Stockholder in connection with the Merger as
provided in Section 2.01(a) shall be proportionately reduced to reflect the
Escrow Stock required to be deposited in Escrow pursuant to this
Section 2.06(a) and the Escrow Agreement, and such Escrow Stock shall be
released to the Company Stockholders or Acquiror, as the case may be, only in
accordance with the terms of this Merger Agreement and the Escrow Agreement. The
fees of the Escrow Agent shall be paid by Acquiror. On the earlier to occur of
(i) five (5) business days after the final determination of the Closing
Adjustment and the Loss Adjustment pursuant to Section 2.06(b) (including,
without limitation, final resolution of any disputes with respect thereto) or
(ii) ninety (90) days after Closing, the Escrow Agent shall deliver to the
Company Stockholders, pro-rata in accordance with the number of shares of
Company Common Stock held by each such Company Stockholder immediately prior to
the Effective Time, the Escrow Stock, after deducting therefrom an amount of
Escrow Stock having a value equal to the sum (which shall not be less than zero)
of the Closing Adjustment, if any, and the Loss Adjustment, if any, and shall
deliver to Acquiror an amount of Escrow Stock having a value equal to such sum;
PROVIDED, HOWEVER, that in the event of any dispute over the sum of the Closing
Adjustment and the Loss Adjustment pursuant to Section 2.06(b), the Escrow Stock
having a value equal to the amount of any disputed Closing Adjustment and Loss
Adjustment (together with a number of shares of Escrow Stock which are, in
Acquiror's reasonable judgment, necessary to cover any expenses of Acquiror
necessary to resolve such dispute) need not be delivered until such dispute is
finally resolved. For purposes of this Section 2.06, the value of each share of
Escrow Stock shall be equal to the Closing Acquiror Stock Price.

    (b)  DETERMINATION OF CLOSING ADJUSTMENT AND LOSS ADJUSTMENT.  The "Closing
Adjustment" shall equal (i) the amount by which the Net Debt of the Company and
the Company Subsidiaries as of the Closing Date is greater or less than
(ii) the Estimated Net Debt as set forth in the certificate required to be
delivered pursuant to Section 7.02(k) of this Merger Agreement. The "Loss
Adjustment" shall equal the amount of any Losses for which Acquiror Indemnified
Persons are entitled to indemnification pursuant to Section 9.02. The Company
will use its best efforts to close its books and records for the period ending
on the Closing Date within five (5) days after the Closing Date and shall
deliver to the Acquiror or, at the request of the Acquiror, to Acquiror and
Arthur Andersen LLP, such books and records as shall be requested by Acquiror or
Arthur Andersen LLP to enable Arthur Andersen LLP to perform an audit of the
consolidated financial statements of the Company as of the Closing Date and to
determine the amount of the Closing Adjustment and the Loss Adjustment. Upon
receipt of such books and records, the Acquiror shall use its best efforts to
cause Arthur Andersen LLP to complete an audit of the consolidated financial
statements of the Company in order to provide Acquiror the information necessary
to calculate the amount of the Closing Adjustment and the Loss Adjustment within
sixty (60) days following receipt of the books and records of the Company.
Acquiror shall deliver to the Stockholders' Representatives a draft copy of such
audited financial statements and the draft

                                      A-9
<PAGE>
determination of the amount of the Closing Adjustment and the Loss Adjustment
promptly upon receipt of such items from Arthur Andersen LLP. The Stockholders'
Representatives shall have the right to review and copy the computations and
review workpapers used in connection with the preparation of the audited
financial statements after providing Arthur Andersen LLP with written releases
reasonably acceptable to Arthur Andersen LLP and the computation of the Closing
Adjustment and the Loss Adjustment. If the Stockholders' Representatives
disagree with the determination of the Closing Adjustment or the Loss
Adjustment, the Stockholders' Representatives shall so notify the Acquiror in
writing within ten (10) days after the date of their receipt of the audited
financial statements and the computation of the Closing Adjustment and the Loss
Adjustment, specifying in detail any point of disagreement; PROVIDED, HOWEVER,
that if the Stockholders' Representatives fail to notify the Acquiror in writing
of the Stockholders' Representatives' disagreement within such ten (10) day
period, the determination of the Closing Adjustment and the Loss Adjustment
shall be final, conclusive and binding on the Parties for purposes of
determining the amount of the Escrow Stock to be delivered to Company
Stockholders pursuant to this Section 2.06, PROVIDED, FURTHER, HOWEVER, that the
sum of the Closing Adjustment and the Loss Adjustment shall not exceed five
percent (5%) of the Transaction Value. The Acquiror and the Stockholders'
Representatives shall negotiate in good faith to resolve any such disagreement.
It is the intent of the Parties hereto that upon final determination of the
Closing Adjustment, if any, and the Loss Adjustment, if any, the net amount of
such adjustments, provided such amount is in Acquiror's favor, shall be paid to
Acquiror from the Escrow Stock pursuant to this section. There shall be no
adjustment in the case of a net sum in the Company's favor but the escrow stock
shall be distributed to the Company Stockholders as provided above.

    (c)  RESOLUTION OF CLOSING ADJUSTMENT.  If any such disagreement with
respect to the Closing Adjustment cannot be resolved by the Acquiror and the
Stockholders' Representatives within fifteen (15) days after the Stockholders'
Representatives have received notice from the Acquiror in accordance with
Section 2.06(b) of the existence of such disagreement, the Acquiror and the
Stockholders' Representatives shall jointly select a nationally recognized
independent public accounting firm (which has not performed any service since
January 1, 1996 for either the Company or the Acquiror or any of their
respective Affiliates (the "Accounting Firm")), to act as an arbitrator to
resolve as expeditiously as possible all points of disagreement with respect to
the Closing Adjustment (or, in the event they are unable to agree, either may
request the San Diego, CA office of the American Arbitration Association to make
such selection, which shall be final and binding on the Parties). All
determinations made by the Accounting Firm with respect to the Closing
Adjustment shall be final, conclusive and binding on the Parties hereto. Each
party shall be responsible for its fees and expenses, as well as one-half of the
fees and expenses of the Accounting Firm, incurred in connection with the
resolution of the Closing Adjustment; PROVIDED, HOWEVER, that any such fees and
expenses incurred on behalf of the Company Stockholders may be paid from any
excess Escrow Stock (that is, any Escrow Stock remaining after the final
distribution to Acquiror of Escrow Stock, if any, in respect of the Closing
Adjustment or the Loss Adjustment) pursuant to the Escrow Agreement.

    (d)  RESOLUTION OF LOSS ADJUSTMENT.  If any such disagreement with respect
to the Loss Adjustment cannot be resolved by the Acquiror and the Stockholders'
Representatives within fifteen (15) days after the Stockholders' Representatives
have received notice from the Acquiror in accordance with Section 2.06(b) of the
existence of such disagreement, the Acquiror and the Stockholders'
Representatives shall submit the matter to the San Diego, CA office of the
American Arbitration Association ("AAA") for binding arbitration to be conducted
in accordance with the AAA commercial arbitration rules in effect at the time
such matter is submitted. If any such matter is submitted to the AAA as provided
herein, (A) each of the Acquiror and the Stockholders' Representatives will
furnish to AAA such workpapers and other documents and information as AAA may
request and will be afforded the opportunity to present to AAA any material
relevant to the matter, (B) the determination by AAA, as set forth in a notice
delivered to the Acquiror and the Stockholders' Representatives by

                                      A-10
<PAGE>
AAA, will be binding and conclusive on such parties and (C) the non-prevailing
party shall be responsible for the fees and expenses incurred in connection with
the resolution of the Loss Adjustment; provided, however, that any such fees and
expenses that are to be paid by the Company Stockholders may be paid from any
excess Escrow Stock (that is, any Escrow Stock remaining after the final
distribution to Acquiror of Escrow Stock, if any, in respect of the Closing
Adjustment or Loss Adjustment) pursuant to the Escrow Agreement.

the right to use all Intangible and Other Property used in the business of

unrelated Persons may involve such infringement or violation) and (ii) no claim
has been asserted, and Company is not aware of any claim which can be asserted,
by any Person against Company or Company Subsidiaries with respect to the use of
any item of Intangible and Other Property challenging or questioning the
validity or effectiveness of such use of any such item, except for such
infringements, violations or claims which are not reasonably likely,
individually or in the aggregate (together with the items set forth in

Subsidiary. Unless specifically noted in Section 3.07 of the Company Disclosure
Letter, no Person (other than employees of Company or any Company Subsidiary)

obligations of the other parties thereto, except as such enforceability may be
subject to the effects of any applicable bankruptcy, insolvency, fraudulent
conveyance, reorganization, moratorium or similar Laws affecting creditors'
rights generally or subject to the effects of general equitable principles
(whether considered in a proceeding in equity or at law). Company has complied
with all of the provisions of such Company Contracts and is not in default
thereunder, and there has not occurred any event which (whether with or without
notice, lapse of time, or the happening or occurrence of any other event) would
constitute such a default, and the execution of this Merger Agreement by Company

Contract to comply with all material provisions thereof which default or failure

Effect, (B) any default by Company or, to the knowledge of Company, any other

Letter or the Acquiror Disclosure Letter, as the case may be, to deliver to the
other as promptly as practicable but in no event later than thirty-one
(31) days prior to the Closing Date, a signed agreement substantially in the
form attached hereto as Exhibit E, in the case of the Company, and Exhibit F, in

Stock held by any such "affiliate" shall not be transferable, regardless of
whether such "affiliate" has provided the applicable signed agreement referred

policies of the SEC, and each of the Company and Acquiror agrees that it shall
take no action that would cause such accounting treatment not to be obtained.

accounted for in Section 2.06 hereof, split, combine or reclassify any shares of

    (b) take any action that is intended or would reasonably be expected to
result in any of Acquiror's representations and warranties set forth in this

the Merger from qualifying as a reorganization under the provisions of
Section 368(a) of the Code; or

    The obligations and liabilities of the Company Stockholders with respect to
their respective indemnities pursuant to this Article IX, resulting from any
Third Party Claim shall be subject to the following terms and conditions:

    (a) The party seeking indemnification (the "Indemnified Party") must give
the party obligated to indemnify (the "Indemnifying Party"), notice of any Third
Party Claim which is asserted against, resulting to, imposed upon or incurred by
the Indemnified Party and which may give rise to liability of the Indemnifying
Party pursuant to this Article IX, stating (to the extent known or reasonably
anticipated) the nature and basis of such Third Party Claim and the amount
thereof; provided that the failure to give such notice shall not affect the
rights of the Indemnified Party hereunder except to the extent (i) that the
Indemnifying Party shall have suffered actual damage by reason of such failure,
or (ii) such failure or delay materially adversely affects the ability of the
Indemnifying Party to defend, settle or compromise such Third Party Claim.

    (b) Subject to Section 9.03(c) below, if the Indemnifying Party assumes
responsibility for Losses arising out of such Third Party Claim, then the
Indemnifying Party shall have the right to undertake, by counsel or other
representatives of its own choosing, the defense of such Third Party Claim at
the Indemnifying Party's risk and expense.

    (c) In the event that (i) the Indemnifying Party shall elect not to
undertake such defense, (ii) within a reasonable time after notice from the
Indemnified Party of any such Third Party Claim, the Indemnifying Party shall
fail to undertake to defend such Third Party Claim, or (iii) there is a
reasonable probability that such Third Party Claim may materially and adversely
affect the Indemnified Party other than as a result of money damages or other
money payments, then the Indemnified Party (upon further written notice to the
Indemnifying Party) shall have the right to undertake the defense, compromise or
settlement of such Third Party Claim, by counsel or other representatives of its
own choosing, on behalf of and for the account and risk of the Indemnifying
Party. In the event that the Indemnified Party undertakes the defense of a Third
Party Claim under this Section 9.03, the Indemnifying Party shall pay to the
Indemnified Party, in addition to the other sums required to be paid hereunder,
the reasonable costs and expenses incurred by the Indemnified Party in
connection with such defense, compromise or settlement as and when such costs
and expenses are so incurred.

    (d) Anything in this Section 9.03 to the contrary notwithstanding,
(i) neither the Indemnified Party nor the Indemnifying Party shall, without the
other party's written consent (which consent shall not be unreasonably withheld

                                    FORM OF
                                ESCROW AGREEMENT

    WHEREAS, pursuant to the Agreement and Plan of Merger dated as of March   ,
2000 by and among Acquiror, Merger Sub and the Company (as amended, the "Merger
Agreement"), the Merger Sub is being merged with and into the Company (the

    WHEREAS, the adoption and approval of the Merger Agreement by the Company
Stockholders also constitutes their approval of the specific terms of the Merger
Agreement provided therein (including this escrow), of the terms and provisions
of this Escrow Agreement, of the appointment of the Escrow Agent, and of the
appointment of each of the Stockholders' Representatives to act on behalf of the
Company Stockholders;

    WHEREAS, pursuant to the terms of the Merger Agreement, the parties thereto
have agreed, as a condition to their respective obligations thereunder, to enter
into this Escrow Agreement; and

    WHEREAS, the Escrow Agent has agreed to act as Escrow Agent hereunder, in
accordance with the terms and conditions hereinafter set forth.

    NOW, THEREFORE, in consideration of the foregoing and of the mutual
covenants and agreements set forth herein, the parties hereto hereby agree as
follows:

    1.  APPOINTMENT OF ESCROW AGENT; COMPENSATION.

    Acquiror, the Company and the Stockholders' Representatives hereby mutually
appoint and designate the Escrow Agent as escrow agent to receive, hold and
disburse the Escrow Stock (as defined in the Merger Agreement), and the Escrow

reasonable fees and expenses of the Escrow Agent.

    2.  ESCROW DEPOSIT.

    At the Effective Time (as defined in the Merger Agreement), Acquiror shall
deliver to the Escrow Agent the Escrow Stock. In connection with any delivery of
any Escrow Stock pursuant to this Escrow Agreement,

        (i) all property ("Escrow Property") that would have been distributed to
    the Company Stockholders as a result of any non-taxable stock dividend,
    stock split, recapitalization, merger, combination or similar transaction
    occurring during the period (the "Post-closing Escrow Period") beginning at
    the Effective Time and ending on the date of disbursement of all Escrow
    Stock pursuant to Section 2.06 of the Merger Agreement, (the "Adjustment
    Date"), which Adjustment Date shall be no later than the date which is
    ninety (90) days after the Closing (as defined in the Merger Agreement),

        (ii) less any Escrow Stock, and any Escrow Property distributed with
    respect thereto, that have been applied as provided in the Merger Agreement
    and this Escrow Agreement in

                                      B-1
<PAGE>
    satisfaction of any Closing Adjustments or Loss Adjustments, if any (as
    defined in Section 2.06 of the Merger Agreement), and

       (iii) less any Escrow Stock, and any Escrow Property, the distribution of
    which is contested pursuant to Section 3(a);

    shall be delivered as soon as practicable after the Adjustment Date as set
forth herein or otherwise in accordance with written instructions provided by
any of the Stockholders' Representatives, for redelivery to the Company
Stockholders based on each such Company Stockholder's proportionate interests
set forth on Exhibit A attached hereto. Notwithstanding such delivery, any
remaining Escrow Stock (and any Escrow Property to be distributed with respect
thereto) held in escrow pursuant to clause (iii) above shall continue to be held
by the Escrow Agent under this Escrow Agreement in accordance with the
provisions of this Escrow Agreement. The Escrow Stock together with any Escrow
Property are sometimes collectively referred to herein as the "Shares." The
Shares shall be registered in the name of the Escrow Agent as escrow agent
hereunder. The Escrow Agent shall hold the Shares for the accounts of the
Company Stockholders in accordance with each Company Stockholder's respective
interest therein, and shall (to the extent legally permissible) vote the Escrow
Stock and any other shares of stock included in the Escrow Property at the
direction of the Stockholders' Representatives. Any cash dividends paid with
respect to the Escrow Stock shall be distributed as, if and when paid to the
Company Stockholders, set forth on Exhibit A attached hereto.

    3.  CONDITIONS OF ESCROW.

    The Escrow Agent shall hold the Shares solely for the benefit of Acquiror
Indemnified Persons and/or the Company Stockholders, as the case may be, as
provided in this Escrow Agreement and the Merger Agreement. The Escrow Agent
shall deliver the Shares to the Acquiror Indemnified Persons and/or the Company
Stockholders only in accordance with the following terms and conditions:

    3(a) If an Acquiror Indemnified Person believes he or it is entitled to a
Closing Adjustment or Loss Adjustment pursuant to the Merger Agreement (an
"Indemnification Amount"), then such Acquiror Indemnified Person may provide
written notice (an "Adjustment Notice") to the Escrow Agent and the
Stockholder's Representatives of the amount of such payment, the basis upon
which such payment is required to be made, and the number of shares of Escrow
Stock deliverable to such Acquiror Indemnified Person (calculated pursuant to
Section 2.06 of the Merger Agreement), with respect thereto on or prior to the
Adjustment Date. The date on which the Adjustment Notice is received by Escrow
Agent and the Stockholders' Representatives shall be the adjustment notice date
(the "Adjustment Notice Date").

        (i) If the Stockholders' Representatives do not deliver to the Escrow
    Agent a notice contesting the determination of the Closing Adjustment or the
    Loss Adjustment as specified in the Adjustment Notice within 15 days after
    the Adjustment Notice Date, then the Escrow Agent shall deliver to such
    Acquiror Indemnified Person the number of Adjustment Escrow Shares specified
    in such notice (together with any Escrow Property to be distributed with
    respect thereto) on the 16th business day after the Adjustment Notice Date.

        (ii) If the Stockholders' Representatives deliver to the Escrow Agent a
    notice (with a copy to the relevant Acquiror Indemnified Person) contesting
    the determination of the Closing Adjustment or the Loss Adjustment as
    specified in the Adjustment Notice within 15 days after the Adjustment
    Notice Date, then the Escrow Agent shall notify the Acquiror Indemnified
    Person thereof on the 16(th) business day after the Adjustment Notice Date
    and the Escrow Agent shall deliver to the Acquiror Indemnified Person only
    the number of shares of Escrow Stock not so contested (together with any
    Escrow Property to be distributed with respect thereto) on the 15th business
    day after the Adjustment Notice Date. Unless the Acquiror Indemnified Person
    and the Stockholders' Representatives deliver a notice to the Escrow Agent
    modifying the provisions of the

                                      B-2
<PAGE>
    Adjustment Notice, the Escrow Stock (together with any Escrow Property to be
    distributed with respect thereto and any additional shares of Escrow Stock
    which the Acquiror Indemnified Person has notified the Escrow Agent in
    writing prior to the 15(th) business day following the Adjustment Notice
    Date are, in the Acquiror's reasonable judgment, necessary to cover any
    expenses which the Acquiror Indemnified Person may waive in connection with
    such dispute ("Expenses Shares")) contested and not so distributed as
    provided in the preceding sentence shall either (i) continue to be held by
    the Escrow Agent pursuant to the terms hereof until such time as the
    (A) Acquiror Indemnified Person and the Stockholders' Representatives shall
    have delivered to the Escrow Agent a jointly executed notice advising the
    Escrow Agent as to how such Escrow Stock shall be delivered or (B) the
    Accounting Firm or the AAA, as the case may be, shall have resolved such
    contest pursuant to Sections 2.06(c) and (d) of the Merger Agreement, in
    which event the Escrow Stock shall be delivered in accordance with such
    resolution.

    3(b) As soon as practicable after the Adjustment Date, the Escrow Agent
shall:

        (i) Deliver to the respective Acquiror Indemnified Persons any Escrow
    Stock to which any Acquiror Indemnified Person remains entitled to under
    Section 3(a) above, together with any Escrow Property to be distributed with
    respect thereto;

        (ii) Set aside for the retention by it for application in accordance
    with the terms of Section 3(a) of this Escrow Agreement any Escrow Stock
    (together with any Escrow Property to be distributed with respect thereto
    and any Expenses Shares) the distribution of which is contested pursuant to
    Section 3(a); and

       (iii) Deliver any remaining Escrow Stock (together with any Escrow
    Property to be distributed with respect thereto) to the Company
    Stockholders, in accordance with written instructions provided by such
    Stockholders' Representatives, for redelivery to the Company Stockholders
    based on each such Company Stockholder's proportionate interest immediately
    following the Effective Time in the Acquiror Shares as set forth in
    Schedule 3 hereto.

    3(c) Notwithstanding the foregoing, in each circumstances under any of the
foregoing provisions in which Acquiror Shares are deliverable to any Acquiror
Indemnified Person, the number of shares so deliverable shall be rounded upward
to the nearest whole number.

    4.  INDEMNIFICATION OF ESCROW AGENT.

    4(a) The Escrow Agent may rely and shall be protected in acting or
refraining from acting upon any certificate or affidavit furnished to it
hereunder and believed by it to be genuine and to have been signed or presented
by the proper party or parties.

    4(b) The Escrow Agent shall not be liable for any action taken by it in good
faith and without negligence and believed by it to be authorized or within the
rights or powers conferred upon it by this Escrow Agreement.

    4(c) Acquiror hereby agrees to indemnify the Escrow Agent for, and hold it
harmless against, any loss, liability or expense incurred without negligence or
bad faith on the part of the Escrow Agent arising out of or in connection with
its entering into this Escrow Agreement and carrying out its duties hereunder,
including costs and expenses of defending itself from any claims of liability
with respect thereto.

    4(d) The Escrow Agent (and any successor Escrow Agent) may at any time
resign as such by delivering the Shares to any successor Escrow Agent jointly
designated in writing by Acquiror and the Stockholders' Representatives or to
any court of competent jurisdiction, whereupon the Escrow Agent shall be
discharged of and from any and all further obligations arising in connection
with this Escrow Agreement. The resignation of the Escrow Agent will take effect
on the earlier of (i) the appointment

                                      B-3
<PAGE>
of a successor (including a court of competent jurisdiction) or (ii) the day
which is 30 days after the date of delivery of its written notice of resignation
to Acquiror and the Stockholders' Representatives. If at that time the Escrow
Agent has not received a designation of a successor Escrow Agent, the Escrow
Agent's sole responsibility after that time shall be to safekeep the Shares
until receipt of a designation of successor Escrow Agent or a joint written
disposition instruction by Acquiror and the Stockholders' Representatives or a
final order of a court of competent jurisdiction.

    4(e) This Escrow Agreement expressly sets forth all the duties of the Escrow
Agent with respect to any and all matters pertinent hereto. No implied duties or
obligations shall be read into this Escrow Agreement against the Escrow Agent.
The Escrow Agent shall not be bound by the provisions of any agreement between
Acquiror, the Company and/or the Stockholders' Representatives except this
Escrow Agreement and, solely for the purposes of defining the Escrow Agent's
responsibilities with respect to this Escrow Agreement and the Merger Agreement.

    4(f) The Escrow Agent does not have any interest in the Shares, but is
serving as escrow holder only, and only has possession thereof.

    5.  TERMINATION.

    This Escrow Agreement shall be terminated when the Shares have been finally
disbursed as provided in Section 3 hereof and may be terminated prior thereto by
written instruction signed by Acquiror and the Stockholders' Representatives.

    6.  WAIVER.

    The waiver by the Stockholders' Representatives of a breach of this Escrow
Agreement by the Escrow Agent shall not constitute a waiver of any right or
remedy the Company Stockholders may have against Acquiror under the Merger
Agreement or hereunder. The waiver by Acquiror of a breach of this Escrow
Agreement by the Escrow Agent shall not constitute a waiver of any right or
remedy it may have against the Company Stockholders under the Merger Agreement
or hereunder. No delay or failure on the part of any party hereto in exercising
any right, power, or privilege under this Escrow Agreement or under any other
agreement or instrument given or entered into in connection with or pursuant to
this Escrow Agreement shall impair any such right, power, or privilege or be
construed as a waiver of any event of default hereunder or any acquiescence
therein. No single or partial exercise of any such right, power, or privilege
shall preclude the further exercise of such right, power, or privilege, or the
exercise of any other right, power, or privilege. No waiver shall be valid
against any party hereto unless made in writing and signed by the party against
whom enforcement of such waiver is sought and then only to the extent expressly
specified therein.

                        DELAWARE GENERAL CORPORATION LAW
                            SS. 262 APPRAISAL RIGHTS

    (a) Any stockholder of a corporation of this State who holds shares of stock
on the date of the making of a demand pursuant to subsection (d) of this section
with respect to such shares, who continuously holds such shares through the
effective date of the merger or consolidation, who has otherwise complied with
subsection (d) of this section and who has neither voted in favor of the merger
or consolidation nor consented thereto in writing pursuant to ss. 228 of this
title shall be entitled to an appraisal by the Court of Chancery of the fair
value of the stockholder's shares of stock under the circumstances described in
subsections (b) and (c) of this section. As used in this section, the word
"stockholder" means a holder of record of stock in a stock corporation and also
a member of record of a nonstock corporation; the words "stock" and "share" mean
and include what is ordinarily meant by those words and also membership or
membership interest of a member of a nonstock corporation; and the words
"depository receipt" mean a receipt or other instrument issued by a depository
representing an interest in one or more shares, or fractions thereof, solely of
stock of a corporation, which stock is deposited with the depository.

    (b) Appraisal rights shall be available for the shares of any class or
series of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to ss. 251 (other than a merger effected pursuant to ss.
251(g) of this title), ss. 252, ss. 254, ss. 257, ss. 258, ss. 263 or ss. 264 of
this title:

        (1) Provided, however, that no appraisal rights under this section shall
    be available for the shares of any class or series of stock, which stock, or
    depository receipts in respect thereof, at the record date fixed to
    determine the stockholders entitled to receive notice of and to vote at the
    meeting of stockholders to act upon the agreement of merger or
    consolidation, were either (i) listed on a national securities exchange or
    designated as a national market system security on an interdealer quotation
    system by the National Association of Securities Dealers, Inc. or (ii) held
    of record by more than 2,000 holders; and further provided that no appraisal
    rights shall be available for any shares of stock of the constituent
    corporation surviving a merger if the merger did not require for its
    approval the vote of the stockholders of the surviving corporation as
    provided in subsection (f) of ss. 251 of this title.

        (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
    under this section shall be available for the shares of any class or series
    of stock of a constituent corporation if the holders thereof are required by
    the terms of an agreement of merger or consolidation pursuant to ss.ss. 251,
    252, 254, 257, 258, 263 and 264 of this title to accept for such stock
    anything except:

           a.  Shares of stock of the corporation surviving or resulting from
       such merger or consolidation, or depository receipts in respect thereof;

           b.  Shares of stock of any other corporation, or depository receipts
       in respect thereof, which shares of stock (or depository receipts in
       respect thereof) or depository receipts at the effective date of the
       merger or consolidation will be either listed on a national securities
       exchange or designated as a national market system security on an
       interdealer quotation system by the National Association of Securities
       Dealers, Inc. or held of record by more than 2,000 holders;

           c.  Cash in lieu of fractional shares or fractional depository
       receipts described in the foregoing subparagraphs a. and b. of this
       paragraph; or

                                      C-1
<PAGE>
           d.  Any combination of the shares of stock, depository receipts and
       cash in lieu of fractional shares or fractional depository receipts
       described in the foregoing subparagraphs a., b. and c. of this paragraph.

        (3) In the event all of the stock of a subsidiary Delaware corporation
    party to a merger effected under ss. 253 of this title is not owned by the
    parent corporation immediately prior to the merger, appraisal rights shall
    be available for the shares of the subsidiary Delaware corporation.

    (c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets of
the corporation. If the certificate of incorporation contains such a provision,
the procedures of this section, including those set forth in subsections
(d) and (e) of this section, shall apply as nearly as is practicable.

    (d) Appraisal rights shall be perfected as follows:

        (1) If a proposed merger or consolidation for which appraisal rights are
    provided under this section is to be submitted for approval at a meeting of
    stockholders, the corporation, not less than 20 days prior to the meeting,
    shall notify each of its stockholders who was such on the record date for
    such meeting with respect to shares for which appraisal rights are available
    pursuant to subsection (b) or (c) hereof that appraisal rights are available
    for any or all of the shares of the constituent corporations, and shall
    include in such notice a copy of this section. Each stockholder electing to
    demand the appraisal of such stockholder's shares shall deliver to the
    corporation, before the taking of the vote on the merger or consolidation, a
    written demand for appraisal of such stockholder's shares. Such demand will
    be sufficient if it reasonably informs the corporation of the identity of
    the stockholder and that the stockholder intends thereby to demand the
    appraisal of such stockholder's shares. A proxy or vote against the merger
    or consolidation shall not constitute such a demand. A stockholder electing
    to take such action must do so by a separate written demand as herein
    provided. Within 10 days after the effective date of such merger or
    consolidation, the surviving or resulting corporation shall notify each
    stockholder of each constituent corporation who has complied with this
    subsection and has not voted in favor of or consented to the merger or
    consolidation of the date that the merger or consolidation has become
    effective; or

        (2) If the merger or consolidation was approved pursuant to ss. 228 or
    ss. 253 of this title, each constituent corporation, either before the
    effective date of the merger or consolidation or within ten days thereafter,
    shall notify each of the holders of any class or series of stock of such
    constituent corporation who are entitled to appraisal rights of the approval
    of the merger or consolidation and that appraisal rights are available for
    any or all shares of such class or series of stock of such constituent
    corporation, and shall include in such notice a copy of this section;
    provided that, if the notice is given on or after the effective date of the
    merger or consolidation, such notice shall be given by the surviving or
    resulting corporation to all such holders of any class or series of stock of
    a constituent corporation that are entitled to appraisal rights. Such notice
    may, and, if given on or after the effective date of the merger or
    consolidation, shall, also notify such stockholders of the effective date of
    the merger or consolidation. Any stockholder entitled to appraisal rights
    may, within 20 days after the date of mailing of such notice, demand in
    writing from the surviving or resulting corporation the appraisal of such
    holder's shares. Such demand will be sufficient if it reasonably informs the
    corporation of the identity of the stockholder and that the stockholder
    intends thereby to demand the appraisal of such holder's shares. If such
    notice did not notify stockholders of the effective date of the merger or
    consolidation, either (i) each such constituent corporation shall send a
    second notice before the effective date of the merger or consolidation
    notifying each of the holders of any class or series of stock of such
    constituent

                                      C-2
<PAGE>
    corporation that are entitled to appraisal rights of the effective date of
    the merger or consolidation or (ii) the surviving or resulting corporation
    shall send such a second notice to all such holders on or within 10 days
    after such effective date; provided, however, that if such second notice is
    sent more than 20 days following the sending of the first notice, such
    second notice need only be sent to each stockholder who is entitled to
    appraisal rights and who has demanded appraisal of such holder's shares in
    accordance with this subsection. An affidavit of the secretary or assistant
    secretary or of the transfer agent of the corporation that is required to
    give either notice that such notice has been given shall, in the absence of
    fraud, be prima facie evidence of the facts stated therein. For purposes of
    determining the stockholders entitled to receive either notice, each
    constituent corporation may fix, in advance, a record date that shall be not
    more than 10 days prior to the date the notice is given, provided, that if
    the notice is given on or after the effective date of the merger or
    consolidation, the record date shall be such effective date. If no record
    date is fixed and the notice is given prior to the effective date, the
    record date shall be the close of business on the day next preceding the day
    on which the notice is given.

    (e) Within 120 days after the effective date of the merger or consolidation,
the surviving or resulting corporation or any stockholder who has complied with
subsections (a) and (d) hereof and who is otherwise entitled to appraisal
rights, may file a petition in the Court of Chancery demanding a determination
of the value of the stock of all such stockholders. Notwithstanding the
foregoing, at any time within 60 days after the effective date of the merger or
consolidation, any stockholder shall have the right to withdraw such
stockholder's demand for appraisal and to accept the terms offered upon the
merger or consolidation. Within 120 days after the effective date of the merger
or consolidation, any stockholder who has complied with the requirements of
subsections (a) and (d) hereof, upon written request, shall be entitled to
receive from the corporation surviving the merger or resulting from the
consolidation a statement setting forth the aggregate number of shares not voted
in favor of the merger or consolidation and with respect to which demands for
appraisal have been received and the aggregate number of holders of such shares.
Such written statement shall be mailed to the stockholder within 10 days after
such stockholder's written request for such a statement is received by the
surviving or resulting corporation or within 10 days after expiration of the
period for delivery of demands for appraisal under subsection (d) hereof,
whichever is later.

    (f) Upon the filing of any such petition by a stockholder, service of a copy
thereof shall be made upon the surviving or resulting corporation, which shall
within 20 days after such service file in the office of the Register in Chancery
in which the petition was filed a duly verified list containing the names and
addresses of all stockholders who have demanded payment for their shares and
with whom agreements as to the value of their shares have not been reached by
the surviving or resulting corporation. If the petition shall be filed by the
surviving or resulting corporation, the petition shall be accompanied by such a
duly verified list. The Register in Chancery, if so ordered by the Court, shall
give notice of the time and place fixed for the hearing of such petition by
registered or certified mail to the surviving or resulting corporation and to
the stockholders shown on the list at the addresses therein stated. Such notice
shall also be given by 1 or more publications at least 1 week before the day of
the hearing, in a newspaper of general circulation published in the City of
Wilmington, Delaware or such publication as the Court deems advisable. The forms
of the notices by mail and by publication shall be approved by the Court, and
the costs thereof shall be borne by the surviving or resulting corporation.

    (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled to
appraisal rights. The Court may require the stockholders who have demanded an
appraisal for their shares and who hold stock represented by certificates to
submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as to
such stockholder.

                                      C-3

    (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any element
of value arising from the accomplishment or expectation of the merger or
consolidation, together with a fair rate of interest, if any, to be paid upon
the amount determined to be the fair value. In determining such fair value, the
Court shall take into account all relevant factors. In determining the fair rate
of interest, the Court may consider all relevant factors, including the rate of
interest which the surviving or resulting corporation would have had to pay to
borrow money during the pendency of the proceeding. Upon application by the
surviving or resulting corporation or by any stockholder entitled to participate
in the appraisal proceeding, the Court may, in its discretion, permit discovery
or other pretrial proceedings and may proceed to trial upon the appraisal prior
to the final determination of the stockholder entitled to an appraisal. Any
stockholder whose name appears on the list filed by the surviving or resulting
corporation pursuant to subsection (f) of this section and who has submitted
such stockholder's certificates of stock to the Register in Chancery, if such is
required, may participate fully in all proceedings until it is finally
determined that such stockholder is not entitled to appraisal rights under this
section.

    (i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to the
stockholders entitled thereto. Interest may be simple or compound, as the Court
may direct. Payment shall be so made to each such stockholder, in the case of
holders of uncertificated stock forthwith, and the case of holders of shares
represented by certificates upon the surrender to the corporation of the
certificates representing such stock. The Court's decree may be enforced as
other decrees in the Court of Chancery may be enforced, whether such surviving
or resulting corporation be a corporation of this State or of any state.

    (j) The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.

    (k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded appraisal rights as provided in subsection (d) of
this section shall be entitled to vote such stock for any purpose or to receive
payment of dividends or other distributions on the stock (except dividends or
other distributions payable to stockholders of record at a date which is prior
to the effective date of the merger or consolidation); provided, however, that
if no petition for an appraisal shall be filed within the time provided in
subsection (e) of this section, or if such stockholder shall deliver to the
surviving or resulting corporation a written withdrawal of such stockholder's
demand for an appraisal and an acceptance of the merger or consolidation, either
within 60 days after the effective date of the merger or consolidation as
provided in subsection (e) of this section or thereafter with the written
approval of the corporation, then the right of such stockholder to an appraisal
shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court
of Chancery shall be dismissed as to any stockholder without the approval of the
Court, and such approval may be conditioned upon such terms as the Court deems
just.

    (l) The shares of the surviving or resulting corporation to which the shares
of such objecting stockholders would have been converted had they assented to
the merger or consolidation shall have the status of authorized and unissued
shares of the surviving or resulting corporation.

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS

    Section 145 of the General Corporation Law of the State of Delaware (the
"Delaware Law") empowers a Delaware corporation to indemnify any persons who
are, or are threatened to be made, parties to any threatened, pending or
completed legal action, suit or proceeding, whether civil, criminal,
administrative or investigative (other than an action by or in the right of such
corporation), by reason of the fact that such person was an officer or director
of such corporation, or is or was serving at the request of such corporation as
a director, officer, employee or agent of another corporation or enterprise. The
indemnity may include expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement of such action, suit or proceeding, provided that
amounts paid in settlement of such action, suit or proceeding, provided that
such officer or director acted in good faith and in a manner he or she
reasonably believed to be in or not opposed to the corporation's best interest,
and, for criminal proceedings, had no reasonable cause to believe his or her
conduct was illegal. A Delaware corporation may indemnify officers and directors
against expenses (including attorney's fees) in connection with the defense or
settlement of an action by or in the right of the corporation under the same
conditions, except that no indemnification is permitted without judicial
approval if the officer or director is successful on the merits or otherwise in
the defense of any action referred to above, the corporation must indemnify him
or her against the expenses which such officer or director actually and
reasonably incurred.

    The Bylaws of Titan contain a provision to limit the personal liability of
the directors of Titan for violations of their fiduciary duty, except to the
extent such limitation of liability is prohibited by the Delaware Law. This
provision eliminates each director's liability to Titan or its stockholders for
monetary damages except (i) for any breach of the director's duty of loyalty to
Titan or its stockholders, (ii) for acts or omissions not in good faith or which
involve intentional misconduct or a knowing violation of law, (iii) under
Section 174 of the Delaware Law providing for liability of directors for
unlawful payment of dividends or unlawful stock purchases or redemptions, or
(iv) for any transaction from which a director derived an improper personal
benefit. The Bylaws of Titan provide that Titan shall indemnify directors and
officers to the fullest extent permitted by law. The effect of these provisions
is to eliminate the personal liability of directors for monetary damages for
actions involving a breach of their fiduciary duty of care, including any such
actions involving gross negligence.

    In addition, Titan has entered into indemnity agreements with its executive
officers and directors whereby Titan obligates itself to indemnify such officers
and directors from any amounts which the officer or director becomes obligated
to pay because of any claim made against him or her arising out of any act or
omission committed while he or she is acting in his or her capacity as a
director and/or officer of Titan.

    Titan maintains directors and officers liability insurance coverage that
insures its officers and directors against certain losses that may arise out of
their positions with Titan and insures Titan for liabilities it may incur to
indemnity its officers and directors.

ITEM 22. UNDERTAKINGS.

    (a) The undersigned Registrant hereby undertakes:

        (1) To file, during any period in which offers or sales are being made,
    a post-effective amendment to this registration statement:

        (i) To include any prospectus required by Section 10(a)(3) of the
            Securities Act of 1933;

        (ii) To reflect in the prospectus any facts or events arising after the
             effective date of the registration statement (or the most recent
             post-effective amendment thereof) which, individually or in the
             aggregate, represent a fundamental change in the information set
             forth in the registration statement. Notwithstanding the foregoing,
             any increase or decrease in volume of securities offered (if the
             total dollar value of securities offered would not exceed that
             which was registered) and any deviation from the low or high and of
             the estimated maximum offering range may be reflected in the form
             of prospectus filed with the Commission pursuant to Rule 424(b) if,
             in the aggregate, the changes in volume and price represent no more
             than a 20 percent change in the maximum offering price set forth in
             the "Calculation of Registration Fee" table in the effective
             registration statement; and

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

        (2) That, for the purpose of determining any liability under the
    Securities Act of 1933, each such post-effective amendment shall be deemed
    to be a new registration statement relating to the securities offered
    therein, and the offering of such securities at that time shall be deemed to
    be the initial BONA FIDE offering thereof.

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

    (b) The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee

                                      II-3
<PAGE>
benefit plan's annual report pursuant to Section 15(d) of the Securities
Exchange Act of 1934) that is incorporated by reference in the registration
statement shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time
shall be deemed to be the initial BONA FIDE offering thereof.

    (c) The undersigned registrant hereby undertakes as follows: that prior to
any public reoffering of the securities registered hereunder through use of a
prospectus that is a part of this registration statement, by any person or party
who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer
undertakes that such reoffering prospectus will contain the information called
for by the applicable registration form with respect to reofferings by persons
who may be deemed underwriters, in addition to the information called for by the
other items of the applicable form.

    (d) The undersigned registrant undertakes that every prospectus (i) that is
filed pursuant to paragraph (c) immediately preceding, or (ii) that purports to
meet the requirements of Section 10(a)(3) of the Act and is used in connection
with an offering of securities subject to Rule 415, will be filed as a part of
an amendment to the registration statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933, each such post-effective amendment shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial BONA FIDE offering thereof.

    (e) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

    (f) The undersigned Registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Item 4, 10(b), 11 or 13 of this form, within one business day of receipt of such
request, and to send the incorporated documents by first class mail or other
equally prompt means. This includes information contained in documents filed
subsequent to the effective date of the registration statements through the date
of responding to the request.

    (g) The undersigned Registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

Ladies and Gentlemen:

                  This opinion is being delivered to you in connection with the
proposed merger of V T Acquisition Corp. ("Acquiror Sub"), a Delaware
corporation and wholly-owned subsidiary of The Titan Corporation ("Acquiror"), a
Delaware corporation, with and into AverStar, Inc. (the "Company"), a Delaware
corporation, with the separate corporate existence of Acquiror Sub ceasing and
the Company continuing as the surviving corporation (the "Merger"). The Merger
will be consummated pursuant to the Agreement and Plan of Merger (the
"Agreement"), dated as of March 24, 2000, by and among Acquiror, Acquiror Sub
and the Company.

                  In connection with the preparation of this opinion, we have
examined and with your consent relied upon (without any independent
investigation or review thereof) the following documents (including all exhibits
and schedules thereto): (1) the Agreement; (2) the Registration Statement on
Form S-4 to be filed with the Securities and Exchange Commission (the
"Registration Statement") and/or the Proxy Statement/Prospectus of Acquiror and
the Company; (3) representations and certifications made to us by Acquiror
(attached hereto as Exhibit A); (4) representations and certifications made to
us by the Company (attached hereto as Exhibit B); and (5) such other instruments
and documents related to the formation, organization and operation of Acquiror,
Acquiror Sub and the Company or to the consummation of the Merger and the
transactions contemplated thereby as we have deemed necessary or appropriate.1/

- ------------------------
1/ All capitalized terms used herein and not otherwise defined shall have the
same meaning as they have in the Agreement. All section references, unless
otherwise indicated, are to the Internal Revenue Code of 1986, as amended (the
"Code").

                            THE PROPOSED TRANSACTION

                  Based solely upon our review of the documents set forth above,
and upon such information as Acquiror, Acquiror Sub and the Company have
provided to us (which we have not attempted to verify in any respect), and in
reliance upon such documents and information, we understand that the proposed
transaction and the relevant facts with respect thereto are as follows:

                  Acquiror is a leading provider of communications and
information solutions to U.S. military and allied government agencies, as well
as to commercial customers. Acquiror Sub was organized solely for the purpose of
accomplishing the merger described below. The Company provides communications
services, information systems and aerospace services predominantly to U.S.
government agencies and commercial customers.

                  For the reasons set forth in the Registration Statement, it is
proposed that pursuant to the Agreement and the laws of the State of Delaware,
Acquiror Sub merge with and into the Company. Acquiror Sub's separate corporate
existence will cease and the Company will be the surviving corporation (the
"Surviving Corporation"). As the Surviving Corporation, the Company will succeed
to all of the assets and liabilities of Acquiror Sub under Delaware corporate
law.

                  By virtue of the Merger, each share of Company Common Stock,
excluding any Treasury Shares and any Dissenting Shares, issued and outstanding
at the Effective Time will be converted into the right to receive Acquiror
Common Stock equal to the Exchange Ratio. The Exchange Ratio will be based on
the average of the closing sale prices of the Acquiror Common Stock on the New
York Stock Exchange for the ten consecutive trading days ending two trading days
immediately before the Closing Date. Fractional shares of Acquiror Common Stock
will not be issued in the Merger. Rather, fractional shares will be rounded up
to the nearest whole share of Acquiror Common Stock. Under Delaware General
Corporation Law, stockholders of the Company are entitled to dissent from the
Merger and to exercise appraisal rights in connection with the Merger. It is a
condition to the obligations of Acquiror and Acquiror Sub to effect the Merger
that the Company Dissenting Stockholders not hold more than 5 percent of the
Company Common Stock.

                         ASSUMPTIONS AND REPRESENTATIONS

                  In connection with rendering this opinion, we have assumed or
obtained representations (and, with your consent, are relying thereon, without
any independent investigation or review thereof, although we are not aware of
any material facts or circumstances contrary to or inconsistent therewith) that:

                  1. All information contained in each of the documents we have
examined and relied upon in connection with the preparation of this opinion is
accurate and completely describes all material facts relevant to our opinion,
all copies are accurate and all signatures are genuine. We have also assumed
that there has been (or will be by the Effective Time of the Merger) due
execution and delivery of all documents where due execution and delivery are
prerequisites to the effectiveness thereof.

                  2. The Merger will be consummated in accordance with
applicable state law and will qualify as a statutory merger under applicable
state law.

                  3. All representations made in the exhibits hereto are true,
correct, and complete in all material respects. Any representation or statement
made "to the best of knowledge" or similarly qualified is correct without such
qualification.

                  4. The Merger will be consummated in accordance with the
Agreement and as described in the Proxy Statement/Prospectus (including
satisfaction of all covenants and conditions to the obligations of the parties
without amendment or waiver thereof); each of Acquiror, Acquiror Sub and the
Company will comply with all reporting obligations with respect to the Merger
required under the Code and the Treasury Regulations thereunder; and the
Agreement and all other documents and instruments referred to therein or in the
Proxy Statement/Prospectus are valid and binding in accordance with their terms.

                    OPINION - FEDERAL INCOME TAX CONSEQUENCES

                  Based upon and subject to the assumptions and qualifications
set forth herein, it is our opinion that for federal income tax purposes: (1)
the Merger will qualify as a reorganization within the meaning of Section 368(a)
of the Code; and (2) the discussion in the Registration Statement under the
heading "Federal Income Tax Consequences," to the extent such discussion
describes applicable federal income tax law, is correct in all material
respects, as of the date hereof.

                  In addition to the assumptions set forth above, this opinion
is subject to the exceptions, limitations and qualifications set forth below:

                  1. This opinion represents and is based upon our best judgment
regarding the application of relevant current provisions of the Code and
interpretations of the foregoing as expressed in existing court decisions,
administrative determinations (including the practices and procedures of the
Internal Revenue Service (the "IRS") in issuing private letter rulings, which
are not binding on the IRS except with respect to the taxpayer that receives
such a ruling) and published rulings and procedures all as of the date hereof.
An opinion of counsel merely represents counsel's best judgment with respect to
the probable outcome on the merits and is not binding on the IRS or the courts.
There can be no assurance that positions contrary to our opinions will not be
taken by the IRS, or that a court considering the issues would not hold contrary
to such opinions. Acquiror has not requested a ruling from the IRS (and no
ruling will be sought) as to any of the federal income tax consequences
addressed in this opinion. Furthermore, no assurance can be given that future
legislative, judicial or administrative changes, on either a prospective or
retroactive basis, would not adversely affect the accuracy of the opinion
expressed herein. Nevertheless, we undertake no responsibility to advise you of
any new developments in the law or in the application or interpretation of the
federal income tax laws.

                  2. This letter addresses only the specific tax opinions set
forth above. This letter does not address any other federal, state, local or
foreign tax consequences that may result from the Merger or any other
transaction (including any transaction undertaken in connection with the
Merger).

                  3. We express no opinion regarding, among other things, the
tax consequences of the Merger (including the opinion set forth above) as
applied to specific stockholders of the Company that may be relevant to
particular classes of the Company shareholders, such as dealers in securities,
corporate shareholders subject to the alternative minimum tax, foreign persons,
and holders of shares acquired upon exercise of stock options or in other
compensatory transactions.

                  4. Our opinion set forth herein is based upon the description
of the contemplated transactions as set forth above in the section captioned
"The Proposed Transaction," the Agreement and the Proxy Statement/Prospectus. If
the actual facts relating to any aspect of the transactions differ from this
description in any material respect, our opinion may become inapplicable. No
opinion is expressed as to any transaction other than those set forth in the
section captioned "The Proposed Transaction," the Agreement and the Proxy
Statement/Prospectus or to any transaction whatsoever, including the Merger, if
all the transactions described in the section captioned "The Proposed
Transaction," the Agreement and the Proxy Statement/Prospectus are not
consummated in accordance with the terms of the section captioned "The Proposed

Transaction," the Agreement and the Proxy Statement/Prospectus and without
waiver or breach of any material provision thereof or if all of the
representations, warranties, statements and assumptions upon which we relied are
not true and accurate at all relevant times. In the event any one of the
statements, representations, warranties or assumptions upon which we have relied
to issue this opinion is incorrect, our opinion might be adversely affected and
may not be relied upon.

                  This opinion is provided to Acquiror only, and without our
prior consent, may not be relied upon, used, circulated, quoted or otherwise
referred to in any manner by any person, firm, governmental authority or entity
whatsoever other than reliance thereon by Acquiror. Notwithstanding the prior
sentence, we hereby consent to the use of the opinion letter as an exhibit to
the Registration Statement and to the use of our name in the Registration
Statement. In giving the consent, we do not thereby admit that we are an
"expert" within the meaning of the Securities Act of 1933, as amended.



                                                     Sincerely yours,
