WHO IS OFFERING TO BUY MY SECURITIES?


    - We are Convergent Acquisition Sub, Inc., a wholly owned subsidiary of
      Convergent Holding Corporation (our Parent), which is currently wholly
      owned by Schlumberger Technology Corporation (STC), which is a wholly
      owned subsidiary of Schlumberger Limited (Schlumberger). We and our Parent

      activities other than in connection with this offer.



    - STC is a Texas corporation that is a United States wholly owned subsidiary
      of Schlumberger, a worldwide leader in technical services. STC operates in
      the United States and is engaged either directly or indirectly, through
      wholly owned subsidiaries, in three primary business segments:


       - oilfield services, which is organized into three product groups:
         reservoir evaluation, reservoir development, and reservoir management,
         that provide exploration and production services required during the
         life of an oil and gas reservoir to the petroleum industry;

       - resource management services, a solutions provider to electricity, gas
         and water resource industry clients, to design, install, operate and
         maintain resource measurement networks and services; and

       - test and transaction services, which provides smart card-based
         solutions, semiconductor test, metrology and handling systems and
         services, and corporate internet protocol and network solutions to
         customers.


    - Please see "The Tender Offer--Information Concerning Us, Our Parent, STC
      and Schlumberger."


WHAT ARE THE CLASSES AND AMOUNTS OF SECURITIES SOUGHT IN THIS OFFER?

    - We are offering to purchase all the issued and outstanding common stock of
      Convergent. Please see the "Introduction" and "The Tender Offer--Terms of
      Our Offer; Expiration Date."

HOW MUCH ARE YOU OFFERING TO PAY AND WHAT IS THE FORM OF PAYMENT?

    - We are offering to pay $8.00 for each share, net to you in cash, less any
      required withholding taxes and without interest. You will not have to pay
      brokerage fees or commissions in connection with our offer. Please see
      "Introduction" and "The Tender Offer--Terms of Our Offer; Expiration
      Date."

WHAT ARE THE MOST SIGNIFICANT CONDITIONS OF YOUR OFFER?

    - We are not obligated to purchase any tendered shares unless, after the
      purchase of all of the tendered shares, we would beneficially own at least
      a majority of the outstanding shares (after giving effect to the
      conversion or exercise of all of the then outstanding options and other
      rights and securities exercisable or convertible into shares, whether or
      not exercised or converted at the time of determination). In calculating
      the number of shares we beneficially own, we are required to count shares
      owned by our Parent and STC and shares that are contributed to our

                                       1
<PAGE>
      Parent by Cinergy Ventures, LLC, a stockholder of Convergent and a
      subsidiary of one of Convergent's largest customers, and members of
      Convergent's senior management team. Please see the "Introduction" "The
      Tender Offer--Terms of Our Offer; Expiration Date," "The Tender
      Offer--Merger Agreement; Subscription and Contribution Agreement; Tender
      and Voting Agreement; Voting Agreement; Exclusivity Agreement;
      Nondisclosure Agreement; Employment Agreements" and "The Tender
      Offer--Conditions of Our Offer."

    - We are not obligated to purchase any shares unless and until all material
      governmental or regulatory notices, approvals or other requirements
      necessary to consummate the merger have been given, obtained or complied
      with, including the applicable waiting period under the U.S. antitrust
      laws have expired or been terminated. Please see "The Tender
      Offer--Conditions of Our Offer" and "The Tender Offer--Legal Matters and
      Regulatory Approvals."

    - Please read "The Tender Offer--Conditions of Our Offer," which sets forth
      in full the conditions to our offer.

WHAT AGREEMENTS DO YOU HAVE WITH CONVERGENT OR ANY OF ITS STOCKHOLDERS RELATING
  TO YOUR OFFER?

    - Prior to our entering into the merger agreement with Convergent, we
      entered into a separate agreement with members of Convergent's senior
      management, whom we refer to as the management investors, and Cinergy, in
      which these parties agreed to contribute shares of Convergent common stock
      to our Parent for shares of our Parent's common stock and to tender in our
      offer all the shares that they do not contribute to our Parent. Generally,
      each of these parties agreed to contribute approximately 80% of their
      holdings in Convergent, except for Cinergy which agreed to contribute 50%
      of its holdings in Convergent. As a result, these stockholders will become
      stockholders of our Parent and will not receive any cash for the shares
      they contribute to our Parent. They will, however, have the opportunity to
      share in any future growth of Convergent, which will be a wholly owned
      subsidiary of our Parent. The shares to be contributed represent
      approximately 28.3% of the Convergent stock on a fully diluted basis.

    - Simultaneously with our entering into the merger agreement, we also
      entered into a voting agreement with the management investors and Cinergy
      in which these parties agreed to vote all of their shares in favor of the
      merger and the merger agreement and against any takeover proposal.

    - Simultaneously with entering into the merger agreement, we also entered
      into a tender and voting agreement with InSight Capital Partners III,
      L.P., InSight Capital Partners III (Cayman), L.P., InSight Capital
      Partners III (Co-Investors), L.P., GS Private Equity Partners II, L.P., GS
      Private Equity Partners II Offshore, L.P., GS Private Equity
      Partners III, L.P., GS Private Equity Partners III Offshore, L.P., NBK/GS
      Private Equity Partners, L.P. and Cinergy Ventures, LLC, whom we refer to
      as the major stockholders. The major stockholders agreed to tender all, or
      in the case of Cinergy, half, of their shares in the tender offer and
      agreed to vote all of their shares in favor of the merger and the merger
      agreement and against any takeover proposal. Cinergy has agreed to
      contribute the other half of its shares to our Parent pursuant to the
      subscription and contribution agreement.

    - Please see "The Tender Offer--Merger Agreement; Subscription and
      Contribution Agreement; Tender and Voting Agreement; Voting Agreement;
      Exclusivity Agreement; Nondisclosure Agreement; Employment Agreements."

DO YOU HAVE ENOUGH FINANCIAL RESOURCES TO MAKE PAYMENT?

    - We will obtain all necessary funds to purchase the shares from our Parent,
      which will obtain these funds from STC. STC will provide the necessary
      funds to us as set forth in "The Tender Offer--Financing of Our Offer and
      the Merger."

                                       2
<PAGE>
IS YOUR FINANCIAL CONDITION RELEVANT TO MY DECISION TO TENDER IN YOUR OFFER?

    - We do not think our financial condition is relevant to your decision to
      tender in our offer because our offer does not contain a financing
      condition, we are offering only cash, and all of the funding that will be
      needed will be provided from STC's existing financial resources, as well
      as the lack of any relevant historical information concerning us.

HOW LONG DO I HAVE TO DECIDE WHETHER TO TENDER IN YOUR OFFER?

    - You will have until at least 12:00 Midnight, New York City time, on
      Monday, November 27, 2000, to tender your shares. If you cannot deliver
      everything that is required in order to make a valid tender by that time,
      you may be able to use the guaranteed delivery procedure that is described
      in "The Tender Offer--Procedures for Accepting Our Offer and Tendering
      Shares."

CAN YOUR OFFER BE EXTENDED, AND UNDER WHAT CIRCUMSTANCES?

    - We have the right, in our sole discretion, but subject to the terms of the
      merger agreement and applicable law, to extend the period of time during
      which our offer remains open. If on November 27, 2000 all conditions to
      our offer are not then satisfied or waived, we have agreed that we will
      extend our offer from time to time until March 31, 2001. Please see "The
      Tender Offer--Terms of Our Offer; Expiration Date" and "The Tender
      Offer--Merger Agreement; Subscription and Contribution Agreement; Tender
      and Voting Agreement; Voting Agreement; Exclusivity Agreement;
      Nondisclosure Agreement; Employment Agreements."

HOW WILL I BE NOTIFIED IF YOUR OFFER IS EXTENDED?

    - If we decide to extend our offer, we will inform Citibank, N.A., our
      Depositary, of that fact, and will issue a press release giving the new
      expiration date no later than 9:00 a.m., New York City time, on the
      business day after the day on which our offer was previously scheduled to
      expire. Please see "The Tender Offer--Terms of Our Offer; Expiration
      Date."

HOW DO I TENDER MY SHARES?

To tender your shares in our offer, you must:

    - complete and sign the accompanying Letter of Transmittal (or a manually
      signed facsimile of the Letter of Transmittal) in accordance with the
      instructions in the Letter of Transmittal and mail or deliver it together
      with your stock certificates and any other required documents, to our
      Depositary or tender your shares by book-entry transfer as described in
      "The Tender Offer--Procedures for Accepting Our Offer and Tendering
      Shares;" or

    - if your stock certificates are not immediately available or if you cannot
      deliver your stock certificates and any other required documents to our
      Depositary prior to the expiration of our offer, or you cannot complete
      the procedure for delivery by book-entry transfer on a timely basis, you
      may still tender your shares if you comply with the guaranteed delivery
      procedures described in "The Tender Offer--Procedures for Accepting Our
      Offer and Tendering Shares."

UNTIL WHAT TIME CAN I WITHDRAW PREVIOUSLY TENDERED SHARES?

    - Except in the case of a subsequent offering period, you may withdraw any
      previously tendered shares at any time prior to the expiration of our
      offer. Please see "The Tender Offer--Withdrawal Rights."

                                       3
<PAGE>
HOW DO I WITHDRAW MY PREVIOUSLY TENDERED SHARES?

    - In order to withdraw your tender of shares, you must deliver a written or
      facsimile notice of withdrawal with the required information to our
      Depositary while you still have the right to withdraw. If you tendered
      shares by giving instructions to a broker or bank, you must instruct the
      broker or bank to arrange for the withdrawal of your shares. Please see
      "The Tender Offer--Withdrawal Rights."

WHAT DOES CONVERGENT'S BOARD OF DIRECTORS THINK OF OUR OFFER?

    - Convergent's board of directors, based in part upon the unanimous
      recommendation of a special committee of independent directors of the
      board, (1) unanimously determined that each of the merger agreement, our
      offer, the merger and the other transactions contemplated by the merger
      agreement is fair to, advisable and in the best interests of Convergent's
      stockholders, (2) unanimously approved the merger agreement, our offer,
      the merger and the transactions contemplated by the merger agreement and
      (3) unanimously recommends that Convergent's stockholders accept our offer
      and tender their shares pursuant to our offer and adopt the merger
      agreement.

    - Please see "Special Factors--Reasons and Recommendations of the Special
      Committee and the Board of Directors of Convergent; Fairness of the
      Transaction."

WHAT WILL HAPPEN IF ALL THE SHARES ARE NOT TENDERED?

    - If we are able to acquire beneficial ownership of at least a majority of
      the outstanding shares on a fully diluted basis, then, in accordance with
      Delaware General Corporation Law, we will merge with and into Convergent,
      and Convergent will become a wholly owned subsidiary of our Parent. In
      calculating the number of shares we beneficially own, we are required to
      count shares owned by our Parent and STC and shares that are contributed
      to our Parent, by Cinergy and by members of Convergent's senior management
      team. Each share of Convergent that is outstanding at the time of the
      merger (other than any shares held in the treasury of Convergent, or owned
      by us, and any shares held by stockholders seeking appraisal rights for
      their shares) will be canceled and converted automatically into the right
      to receive the same consideration as stockholders who tendered their
      shares in our offer received.

    - If we are not able to acquire beneficial ownership of at least a majority
      of the outstanding shares on a fully diluted basis, we will either
      purchase those shares which have been tendered, extend our offer or
      terminate our offer in the manner specified in the merger agreement.

    - Because the management investors and Cinergy are contributing
      approximately 28.3% of the outstanding Convergent common stock to our
      Parent and the management investors have agreed to tender approximately
      3.5% of the outstanding Convergent common stock, and because several
      venture capital investors, including Cinergy, have agreed to tender
      approximately 23.7% of the outstanding Convergent common stock, on a fully
      diluted basis, we anticipate that we will acquire at least a majority of
      Convergent's outstanding shares. See "The Tender Offer--Merger Agreement;
      Subscription and Contribution Agreement; Tender and Voting Agreement;
      Voting Agreement; Exclusivity Agreement; Nondisclosure Agreement;
      Employment Agreements."

    - If all of the conditions to our offer have been satisfied or waived, we
      may commence a subsequent offering period of up to 20 business days for
      the purpose of securing tenders of enough shares so that after we buy
      shares in the subsequent offering period, we will own at least 90% of the
      outstanding shares of Convergent common stock. We will pay the same price
      per share in the subsequent offering period as we pay in our offer. Our
      ownership of 90% or more of the shares of Convergent may allow us to
      complete a "short form" merger. This type of merger will not require
      Convergent to hold a stockholders' meeting to approve the merger. See

                                       4
<PAGE>
      "Introduction," "Special Factors--Purposes, Alternatives, Effects and
      Plans" and "The Tender Offer--Legal Matters and Regulatory Approvals."

WILL CONVERGENT CONTINUE AS A PUBLIC COMPANY?

    - If the merger occurs, Convergent will no longer be publicly owned. Even if
      the merger does not occur, if we purchase all the tendered shares,
      (1) there may be so few remaining stockholders and publicly held shares
      that the Convergent common stock may no longer be eligible to trade on the
      Nasdaq National Market, (2) there may not be a public trading market for
      the Convergent common stock, and (3) Convergent may cease making filings
      with the SEC or otherwise cease being required to comply with SEC rules
      relating to publicly held companies. Please see "Special
      Factors--Purposes, Alternatives, Effects and Plans" and "The Tender
      Offer--Possible Effects of Our Offer on the Market for the Shares; Nasdaq
      Listing; Margin Regulations and Exchange Act Registration."

IF I DECIDE NOT TO TENDER, HOW WILL YOUR OFFER AFFECT MY SHARES?

    - If you decide not to tender your shares in our offer and the merger
      occurs, you will receive in the merger the same amount of cash per share
      as you would have received if you tendered your shares in our offer.

    - If you decide not to tender your shares in our offer and the merger does
      not occur, if we purchase all the tendered shares, (1) there may be so few
      remaining stockholders and publicly held shares that the Convergent common
      stock will no longer be eligible to trade on the Nasdaq National Market,
      (2) there may not be a public trading market for the Convergent common
      stock, or (3) Convergent may cease making filings with the SEC or
      otherwise cease being required to comply with SEC rules relating to
      publicly held companies. Please see "The Tender Offer--Possible Effects of
      Our Offer on the Market for the Shares; Nasdaq Listing; Margin Regulations
      and Exchange Act Registration."

WILL I HAVE APPRAISAL RIGHTS?

    - We do not believe that appraisal rights are available in connection with
      our offer; however, appraisal rights may be available in connection with
      the merger. If the merger is consummated, stockholders who have not
      tendered their shares may have the right under Delaware law to dissent
      from the merger and demand appraisal of, and to receive payment in cash of
      the fair value of, their shares. See "The Tender Offer--State Take-Over
      Laws" and "The Tender Offer--Rights of Dissenting Stockholders."

WHAT IS THE MARKET VALUE OF MY SHARES AS OF A RECENT DATE?

    - On October 13, 2000, the last full trading day before we announced our
      offer, the closing price per share on the Nasdaq National Market was $4.72
      per share. On October 25, 2000, the last full day of trading before the
      printing of this Offer to Purchase, the closing price per share on the
      Nasdaq National Market was $7.84. See "The Tender Offer--Price Range of
      Convergent's Common Stock."

WITH WHOM MAY I TALK IF I HAVE QUESTIONS ABOUT YOUR OFFER?

    - You can call (toll free) D.F. King & Co., Inc., our Information Agent, at
      (800) 714-3305, or Salomon Smith Barney Inc., our Dealer Manager at
      (877) 518-9871. See the back cover of this document.

SECURITIES EXERCISABLE OR CONVERTIBLE INTO SHARES OF CONVERGENT COMMON STOCK,
WHETHER OR NOT EXERCISED OR CONVERTED AT THE TIME OF DETERMINATION), EXCLUDING
ANY SHARES OF CONVERGENT COMMON STOCK HELD BY CONVERGENT OR ANY OF ITS
SUBSIDIARIES, AND (2) ALL MATERIAL GOVERNMENTAL OR REGULATORY NOTICES, APPROVALS
OR OTHER REQUIREMENTS NECESSARY TO CONSUMMATE THE MERGER SHALL HAVE BEEN GIVEN,
OBTAINED OR COMPLIED WITH, INCLUDING THE EXPIRATION OR TERMINATION OF THE

ABOVE AS THE MINIMUM CONDITION. OUR OFFER IS ALSO SUBJECT TO OTHER CONDITIONS
CONTAINED IN THIS DOCUMENT. WE REFER YOU TO "THE TENDER OFFER--CONDITIONS OF OUR
OFFER," WHICH SETS FORTH IN FULL THE CONDITIONS TO OUR OFFER.

    We are making this offer pursuant to an Agreement and Plan of Merger, dated
as of October 13, 2000, by and among us, our Parent, STC and Convergent. The
merger agreement provides, among other things, that as promptly as practicable
after the purchase of shares pursuant to our offer and the satisfaction or, if
permissible, waiver of the other conditions set forth in the merger agreement
and in accordance with the relevant provisions of the Delaware General
Corporation Law, we will be merged

                                       6
<PAGE>
with and into Convergent. At the effective time of the merger, each share issued
and outstanding immediately prior to the effective time of the merger (other
than shares held in the treasury of Convergent and other than shares held by
stockholders who will have demanded and perfected appraisal rights under
applicable law) will be canceled and converted automatically into the right to
receive $8.00 in cash (or any higher price that may be paid per share in our
offer) without interest. The merger agreement is more fully described in "The
Tender Offer--Merger Agreement; Subscription and Contribution Agreement; Tender
and Voting Agreement; Voting Agreement; Exclusivity Agreement; Nondisclosure
Agreement; Employment Agreements." The material federal income tax consequences
of the sale of shares pursuant to our offer and the merger are described in "The
Tender Offer--Material Federal Income Tax Consequences."

    Prior to the execution of the merger agreement, Cinergy, six of Convergent's
most senior executive officers (including its chief executive officer and its
chief financial officer) and 27 other executives of Convergent have agreed to
contribute a portion of their shares to us prior to the merger and to tender the
remaining portion pursuant to a subscription and contribution agreement. There
are potential conflicts of interest that the Convergent board of directors had
to consider with respect to the transaction, which are described in more detail
in "Special Factors--Reasons and Recommendations of the Special Committee and
the Board of Directors of Convergent; Fairness of the Transaction."

    Simultaneously with the execution of the merger agreement, we, our Parent
and STC entered into a voting agreement with the management investors and
Cinergy which obligates each of them to, among other things:

    - vote (1) in favor of the merger and the merger agreement, (2) against any
      Acquisition Proposal (as that term is defined in the merger agreement),
      against any proposal for action or agreement that would result in a breach
      of any covenant, representation or warranty or any other obligation or
      agreement of Convergent under the merger agreement, against any change in
      the directors of Convergent, against any change in the present
      capitalization of Convergent, against any amendment to Convergent's
      certificate of incorporation or bylaws which in each case could reasonably
      be expected to impede, interfere with, delay, postpone or materially
      adversely affect the transactions contemplated by the merger agreement or
      the likelihood of the transactions being consummated and (3) in favor of
      any other matter necessary for consummation of the transactions
      contemplated by the merger agreement;

    - execute any documents which are necessary or appropriate in order to
      effectuate the foregoing, including the ability for us or our nominees to
      vote shares owned by the management investors;

    - waive any rights of appraisal or rights to dissent from the merger; and

    - (1) revoke all prior proxies or powers of attorney governing the shares
      owned by them and (2) grant an irrevocable proxy to us and our Parent, or
      any of its nominees to vote and act (by written consent or otherwise) with
      respect to all of the shares owned by them at any meeting of Convergent's
      stockholders or by written consent in lieu of any meetings with regard to
      any matter covered in the paragraph above. See "The Tender Offer--Merger
      Agreement; Subscription and Contribution Agreement; Tender and Voting
      Agreement; Voting Agreement; Exclusivity Agreement; Nondisclosure
      Agreement; Employment Agreements."

    Simultaneously with the execution of the merger agreement, we, our Parent
and STC entered into a tender and voting agreement with the major stockholders,
which obligates the major stockholders to, among other things:

    - tender all of their shares of Convergent common stock to us in our offer,
      with the exception of Cinergy who will tender 50% of its shares in our
      offer and contribute 50% of its shares to our Parent pursuant to the
      subscription and contribution agreement;

                                       7
<PAGE>
    - vote (1) in favor of the merger and the merger agreement, (2) against any
      Acquisition Proposal (as that term is defined in the merger agreement),
      against any proposal for action or agreement that would result in a breach
      of any covenant, representation or warranty or any other obligation or
      agreement of Convergent under the merger agreement, against any change in
      the directors of Convergent, against any change in the present
      capitalization of Convergent, against any amendment to Convergent's
      certificate of incorporation or bylaws which in each case could reasonably
      be expected to impede, interfere with, delay, postpone or materially
      adversely affect the transactions contemplated by the merger agreement or
      the likelihood of the transactions being consummated and (3) in favor of
      any other matter necessary for consummation of the transactions
      contemplated by the merger agreement;

    - execute any documents which are necessary or appropriate in order to
      effectuate the foregoing, including the ability for us or our nominees to
      vote shares owned by the major stockholders;

    - waive any rights of appraisal or rights to dissent from the merger; and

    - (1) revoke all prior proxies or powers of attorney governing the shares
      owned by them and (2) grant an irrevocable proxy to us and our Parent, or
      any of our nominees to vote and act (by written consent or otherwise) with
      respect to all of the shares owned by them at any meeting of Convergent's
      stockholders or by written consent in lieu of any meetings with regard to
      any matter covered in the paragraph above.

    Pursuant to the tender and voting agreement, the major stockholders will
receive $8.00 per share of Convergent common stock tendered in our offer, the
same consideration to be received by the public stockholders.

    See "The Tender Offer--Merger Agreement; Subscription and Contribution
Agreement; Tender and Voting Agreement; Voting Agreement; Exclusivity Agreement;
Nondisclosure Agreement; Employment Agreements."

    The merger agreement provides that promptly after the later to occur of
(1) the purchase of and payment for any shares as a result of which Parent and
its subsidiaries own at least a majority of then outstanding shares (together
with the shares beneficially owned by us and STC, including, the shares to be
contributed to our Parent pursuant to the subscription and contribution
agreement) and (2) compliance with Section 14f-1 of the Exchange Act, and the
SEC's Rule 14f-1, our Parent will be entitled to designate the number of
directors on Convergent's board of directors as will give our Parent
representation proportionate to the percentage of the total outstanding number
of shares that our Parent or any of its subsidiaries beneficially owns.
Convergent will, upon request of our Parent, use its best efforts promptly
either to increase the size of its board of directors or to secure the
resignations of some of its incumbent directors, or both as is necessary to
enable our Parent's designees to be so elected or appointed to Convergent's
board of directors, and Convergent will take all actions available to Convergent
to cause our Parent's designees to be elected or appointed at that time.

    We will complete the merger if conditions specified in the merger agreement
are satisfied, including the consummation of our offer, and, if required under
Delaware law, the adoption of the merger agreement at a meeting of Convergent's
stockholders. For a more detailed description of the conditions to the merger,
please see "The Tender Offer--Merger Agreement; Subscription and Contribution
Agreement; Tender and Voting Agreement; Voting Agreement; Exclusivity Agreement;
Nondisclosure Agreement; Employment Agreements" and "The Tender
Offer--Conditions of Our Offer." The affirmative vote of the holders of at least
a majority of the outstanding shares of Convergent common stock is required to
adopt the merger agreement. Consequently, if we acquire (pursuant to our offer
or otherwise) at least a majority of the outstanding shares, then we will be
able to adopt the merger agreement without the affirmative vote of any other
stockholder. See "The Tender Offer--Merger Agreement; Subscription and
Contribution Agreement; Tender and Voting Agreement;

                                       8
<PAGE>
Voting Agreement; Exclusivity Agreement; Nondisclosure Agreement; Employment
Agreements" and "The Tender Offer--Conditions of Our Offer."

    Under Delaware law, if we, together with our Parent, acquire, pursuant to
our offer, the subscription and contribution agreement or otherwise, at least
90% of the then outstanding shares of Convergent capital stock, we will be able
effect the merger without holding a meeting of Convergent's stockholders to vote
on the merger and without requesting the affirmative vote of Convergent's other
stockholders. If that happens, we, our Parent and Convergent have agreed to take
all necessary and appropriate action to cause the merger to become effective in
accordance with Delaware law as soon as practicable after we acquire 90% of the
then outstanding shares without a meeting of Convergent's stockholders. If,
however, we do not acquire at least 90% of the then outstanding shares and a
meeting of Convergent's stockholders to approve the merger is required under
Delaware law, a significantly longer period of time will be required in order to
effect the merger. See "The Tender Offer--Legal Matters and Regulatory
Approvals."

    Convergent has advised us that as of October 13, 2000, 43,414,402 shares
were issued and outstanding, 4,484,786 shares were subject to outstanding and
exercisable stock options, and 5,000 shares were held in the treasury of
Convergent. As a result, as of October 13, 2000:

    - our Minimum Condition would be satisfied if we had acquired 23,949,595
      shares;

    - we would have been able to approve the merger without the calling a
      meeting of Convergent's stockholders or getting the consent or vote of any
      other Convergent stockholder, if we had acquired 43,109,270 shares.

    - Because the management investors and Cinergy are contributing
      approximately 28.3% of the outstanding Convergent common stock to our
      Parent, and the management investors have agreed to tender approximately
      3.5% of the outstanding Convergent common stock, and because several
      venture capital investors, including Cinergy, have agreed to tender
      approximately 23.7% of the outstanding Convergent common stock, on a fully
      diluted basis, we anticipate that the Minimum Condition will be satisfied.
      See "The Tender Offer--Merger Agreement; Subscription and Contribution
      Agreement; Tender and Voting Agreement; Voting Agreement; Exclusivity
      Agreement; Nondisclosure Agreement; Employment Agreements."

    We do not believe that appraisal rights are available in connection with our
offer; however, appraisal rights may be available in connection with the merger.
If the merger is consummated, stockholders who have not tendered their shares
may have the right under Delaware law to dissent from the merger and demand
appraisal of, and to receive payment in cash of the fair value of, their shares.
See "The Tender Offer--State Take-Over Laws" and "The Tender Offer--Rights of
Dissenting Stockholders."

                                SPECIAL FACTORS

1.  BACKGROUND OF OUR OFFER; CONTACTS WITH CONVERGENT, NEGOTIATIONS AND
    AGREEMENTS.


    The following information (other than information concerning us, our Parent,
STC or Schlumberger (or their affiliates) has been provided to us by Convergent:



    During 1999 and the first three quarters of 2000, Convergent's management
pursued several growth strategies in the market for eBusiness solutions for
utility and local government clients, including an initial public offering of
its common stock and possible strategic relationships with a number of
companies, including Schlumberger or one or more of its subsidiaries.
Convergent's management believed that a strategic relationship with Schlumberger
could complement Convergent's growth strategy by offering synergies with STC's
businesses and expertise in providing solutions and technologies, particularly
to the utility industry. In addition, Convergent's Digital Utility solution
could


                                       9
<PAGE>

provide Schlumberger with direct, real-time access to services and information
and reduce utility transaction and operational costs by enabling end-to-end
automation of customers' business processes. Digital Utility offers eBusiness
solutions for front-office applications, including call center and customer
relationship management; back-office applications such as finance, accounting
and human resources; and energy delivery applications such as mobile work force
and outage management. Convergent also believed that a strategic relationship
with Schlumberger could allow it to expand the scope of its Digital Utility to
include revenue management, load data management and fixed network optimization,
areas in which Schlumberger could provide significant expertise.



    As a result, in the spring and early summer of 2000, representatives of
Convergent and Schlumberger held several meetings to discuss a possible business
relationship. During these meetings, representatives of Convergent informed
Schlumberger that Convergent was preparing for an initial public offering. The
discussions focused exclusively on the feasibility of establishing a cooperative
business relationship. During this period, consistent with its normal and
customary practice, Convergent was also holding similar discussions with other
companies.



    As a result of those discussions, Convergent and Schlumberger Industries
S.A., a subsidiary of Schlumberger, entered into a nondisclosure agreement on
July 6, 2000, whereby Convergent agreed to provide information to Schlumberger
to enable Schlumberger to evaluate a possible business relationship with
Convergent. On August 4, 2000, the nondisclosure agreement was amended to make
the exchange of information between Convergent and Schlumberger reciprocal in
order to prepare a joint business plan with the aim to identify and quantify the
opportunities resulting from a possible business relationship. During this
period, the discussions between the parties continued and Convergent and
Schlumberger explored numerous areas of possible cooperation and Schlumberger
undertook a limited due diligence investigation.



    On August 4, 2000, Convergent completed its initial public offering at a
price of $7.00 per share of its common stock. From the time of its initial
public offering, the per share price of Convergent's common stock has declined.
Following the initial public offering, representatives of Schlumberger and
Convergent continued their ongoing discussion of synergies and areas of possible
joint cooperation between the two firms. Thereafter, in early-September 2000,
for the first time, representatives of Schlumberger approached representatives
of InSight Capital Partners, one of the venture capital investors in Convergent,
to discuss the possibility of STC's acquisition of all of the various venture
capital investors' shares of Convergent's common stock. Representatives of
InSight declined to discuss any possible transaction with STC unless STC offered
all holders of Convergent's common stock the possibility to participate on the
same terms. STC and Schlumberger also concluded that the risks associated with
individually negotiated purchases from the venture capital firms outweighed the
speed of acquiring control of Convergent through a series of private placements.



    Thereafter, representatives of STC and Schlumberger had meetings and
telephone calls with representatives of Convergent to discuss the timing and
structure of a proposal, and expanded the scope of their due diligence. On
September 13, 2000, Schlumberger delivered to Convergent a non-binding
expression of interest and a term sheet in connection with a proposed
acquisition of Convergent through a tender offer for all of the shares of
Convergent common stock held by the public and a subsequent merger.
Schlumberger's proposal was conditioned on management's contribution of all, or
a substantial part, of management's shares of Convergent in exchange for shares
of a newly formed holding company for Convergent and the execution of new
employment agreements with a significant number of members of management. The
proposal also contemplated the contribution by Cinergy of all of its shares of
Convergent to the newly formed holding company in exchange for shares of the
newly formed holding company. Convergent's management would continue to be
employed by the surviving corporation. Schlumberger requested a 21-day
exclusivity period to complete its due diligence and to prepare definitive
documentation.


                                       10
<PAGE>

    On September 14, 2000, Convergent informed Schlumberger that a 21 day
exclusivity period was too long and indicated that it would be willing to enter
into an exclusivity period until September 20, 2000. After negotiations, the
parties entered into an exclusivity agreement on September 20, 2000, whereby
Convergent granted Schlumberger an exclusivity period until September 29, 2000.



    The board of directors of Convergent held a special meeting on September 18,
2000 to consider the Schlumberger proposal. The board determined that it would
be willing to consider a proposal if Schlumberger indicated a serious interest
in acquiring Convergent at a price that provided Convergent's stockholders with
a substantial premium over the then-current market price of Convergent's common
stock. Subsequent discussions with Schlumberger and STC resulted in a
preliminary proposal by Schlumberger and STC suggesting a cash price of $10.00
per share of Convergent common stock. Convergent's board of directors noted that
the $10.00 price represented a substantial premium over Convergent's market
price at the time. As of the close of the Nasdaq National Market on the previous
trading day, the price per share of Convergent common stock was $4.50.



    At the September 18 board meeting Convergent's board of directors considered
the qualifications of each of its members to serve on a special committee of the
board of directors that would be formed to review, evaluate and negotiate the
terms and conditions of the Schlumberger and STC proposal and to report final
recommendations regarding the proposed merger to the board. Because two of
Convergent's executive officers, Glenn E. Montgomery, Jr. and Scott M. Schley,
also serve on Convergent's board of directors, and based on Schlumberger's and
STC's proposal, were expected to remain employed by Convergent following the
closing of the offer and the merger and to contribute a substantial portion of
their Convergent common stock to the newly formed holding company, the board
determined that a special committee comprised solely of the board's three
remaining directors be formed to review, evaluate and negotiate the merger
agreement and the terms of our offer. Convergent's board established a special
committee consisting of Jerry Murdock, John W. Blend, III and Robert Sharpe,
constituting all of the non-employee directors of Convergent.



    At that time, Convergent's board of directors also authorized the engagement
of Morgan Stanley to serve as the special committee's financial advisor for the
purpose of (1) assisting in the negotiations with Schlumberger and STC, (2)
advising the special committee with respect to the fairness of the transaction
from a financial point of view and (3) delivering a fairness opinion to the
special committee in connection with the proposed transaction.



    During various periods throughout September 2000, representatives of
Schlumberger and STC conducted further due diligence of Convergent at
Convergent's offices in Greenwood Village, Colorado.



    On September 21, 2000, STC's outside counsel, Brobeck Phleger & Harrison
LLP, delivered a draft merger agreement and other ancillary agreements. Although
the draft merger agreement did not contain pricing terms, the special committee
evaluated the agreement based on the special committee's expectation that STC
would make an offer at a price reflecting a premium to the then-current market
price. The draft merger agreement provided extensive representations and
warranties to be made by Convergent; numerous conditions to STC's offer; an
agreement by Convergent restricting it from pursuing a superior proposal; a 4%
termination fee; and the granting to STC of an option to purchase 19.9% of the
shares of Convergent common stock. The draft tender and voting agreement also
granted STC an option to acquire the shares of the significant venture capital
investors in Convergent.



    On September 21, 2000, Brobeck also delivered drafts of the subscription and
contribution agreement and voting agreement to Holland & Hart LLP, counsel to
certain of the management investors. The documents reflected that Cinergy had
agreed to contribute only 50% of its Convergent common stock to Parent. Over the
next two weeks, the terms of these agreements were negotiated by STC, management
and their respective counsel. In addition, during this period representatives of
STC and Mr. Montgomery negotiated with representatives of Cinergy regarding the
terms of Cinergy's participation in the transaction.


                                       11
<PAGE>
    During the period from September 24 through September 28, 2000, the special
committee adopted organizational resolutions and elected Mr. Sharpe as its
chairman. The committee also reviewed the progress of the negotiations with its
legal and financial advisors, O'Sullivan Graev & Karabell LLP and Morgan
Stanley, respectively, and O'Sullivan Graev & Karabell reviewed in detail with
the special committee the terms of the merger agreement. At the direction of the
special committee, O'Sullivan Graev & Karabell and Morgan Stanley were directed
to proceed with the negotiation of the merger agreement and the other ancillary
documents in accordance with the instructions of the special committee.


    On September 25, 2000 O'Sullivan Graev & Karabell delivered detailed
comments to the draft merger agreement and advised STC that the special
committee had rejected various terms of the initial merger proposal including,
among other things, the granting to us of an option to purchase 19.9% of the
outstanding shares of Convergent's common stock, the amount of the termination
fee and the expense reimbursement provisions. On September 26, O'Sullivan
Graev & Karabell negotiated a number of the terms of the merger agreement with
Brobeck, making progress on the scope of Convergent's representations and
warranties and conditions to STC's offer and the timing and trigger of the
termination fee. At that time, STC dropped its requirements for an option to
purchase 19.9% of the outstanding shares of Convergent's common stock. The
parties, however, did not make progress on the amount of the termination fee.


    On September 28, 2000, O'Sullivan Graev & Karabell and Brobeck continued to
negotiate the terms of the merger agreement. During this meeting, STC agreed to
a reduced termination fee of $10 million, and an expense reimbursement provision
capped at a $2.5 million, which together represented approximately 3% of the
proposed transaction value.

    On September 29, 2000, Holland & Hart, LLP, counsel to certain of the
management investors provided its initial draft of employment agreements to
Brobeck.

    In the evening of September 29, 2000, the exclusivity agreement was extended
until October 6, 2000.

    From September 29 through October 6, 2000, Holland & Hart negotiated the
terms of employment agreements for Mr. Montgomery, the executive vice presidents
and the vice presidents of Convergent.


    Thereafter, during the first week of October negotiations between
representatives of STC and the special committee centered on, among other
issues, (1) the participation of venture funds managed by affiliates of Goldman,
Sachs & Co. in the transaction, (2) the circumstances surrounding the payment of
the termination fee, (3) Cinergy's participation in the transaction and
Convergent's future business relationship with Cinergy and (4) the possibility
of a reduction to the purchase price as a result of due diligence findings by
STC and Schlumberger.


    During the course of those several weeks, O'Sullivan Graev & Karabell,
Holland & Hart and Morgan Stanley provided updates and advice at several
meetings of management and the special committee, at the conclusion of which,
Holland & Hart and O'Sullivan Graev & Karabell were directed to proceed with the
negotiations in accordance with the instructions of management and the special
committee, respectively. In addition, during this period O'Sullivan Graev &
Karabell had numerous conversations with the chairman of the special committee
regarding various issues.


    On October 5, 2000, O'Sullivan Graev & Karabell informed the special
committee that STC had indicated that, based on due diligence findings that,
among other things, Convergent was exceeding its estimated burden rate for 2000
and that unbilled revenue had increased since 1999, STC would be prepared to
move forward with the proposal only if the purchase price per share were reduced
to $9.90 per share. At the direction of the special committee, representatives
of Morgan Stanley advised representatives of STC that the special committee was
not prepared to accept STC's initial price


                                       12
<PAGE>

reduction proposal. The parties to the negotiation ultimately settled on a
reduced price of $9.93 per share and Convergent agreed to present this reduced
price to its board of directors. Morgan Stanley evaluated the transaction in
light of the proposed reduction to the consideration to be paid to Convergent's
stockholders and discussed with the special committee the terms of the proposed
transaction. At that stage, the special committee and management directed their
respective advisors to proceed with the negotiations and work towards finalizing
the documents. At this point in the negotiations, the extent of management's and
Cinergy's participation in the proposed transactions and numerous issues
concerning the employment agreements remained open.



    Late on October 5, 2000, Cinergy's management informed STC's management of
their unwillingness to contribute any of their Convergent shares to the newly
formed holding company but that they would tender all of their shares in the
tender offer.



    On October 9, 2000, STC indicated to Convergent's board of directors that it
would move forward with the proposed transaction only if the following revised
terms were satisfied: (1) the price per share was further reduced, (2) Cinergy
agreed to maintain 50% of its current investment in Convergent and (3) the
documents evidencing the new terms of the transaction were executed on or prior
to October 13, 2000. Based upon these new facts, Mr. Montgomery was authorized
to inform STC that unless STC provided a more definitive revised proposal,
including the price at which STC would be prepared to go forward with the
transaction, Convergent's negotiations would cease with STC.


    The revised terms resulted primarily from STC's growing concern over the
weakness of the e-consulting market and the market generally, as well as its
uncertainty regarding the future of the customer relationship between Cinergy
and Convergent.

    Subsequently, during a special meeting of Convergent's board of directors on
October 10, 2000, the board was informed that STC had presented a revised
proposal which included a new price per share of $8.00. The revised proposal
also included STC's previously stated conditions regarding Cinergy's continued
investment and the timely execution of all transaction documents. Convergent's
board of directors unanimously agreed that before taking any action with respect
to the new proposal, the venture capital investors in Convergent should evaluate
the revised proposal and if desired, pursue negotiations directly with STC.
Following that meeting, from October 10, 2000 until the morning of October 13,
2000, representatives of InSight had discussions with STC regarding the price,
the involvement of each of the venture capital investors in Convergent in the
proposed transactions, the timing of the execution of the documents and the
consummation of the related transactions and the other matters discussed during
the course of the October 10, 2000 meeting of Convergent's board of directors.

    The special committee directed O'Sullivan Graev & Karabell to inform Brobeck
that Convergent would not proceed with the revised STC proposal unless STC
agreed to (1) the elimination of any restrictions on the right of the major
stockholders to solicit superior proposals; (2) a reduction to (A) the
transaction's termination fee and (B) the expense reimbursement obligations of
Convergent and (3) the elimination of STC's option to purchase the shares held
by the major stockholders.

    During that same time period, O'Sullivan Graev & Karabell negotiated with
Brobeck other aspects of the proposed transaction. As a result, at a special
meeting of Convergent's board of directors in the morning of October 13, 2000,
the board and O'Sullivan Graev & Karabell were informed that STC was prepared to
proceed with a revised proposal on the following terms: (1) a purchase price of
$8.00 per share; (2) the elimination of any restrictions on the right of the
major stockholders to solicit superior proposals; (3) a reduction to (A) the
transaction's break-up fee from $10 million to $8.0 million and (B) the expense
reimbursement obligations of Convergent from $2.5 million to $2.0 million;
(4) STC would not have an option to purchase the shares held by any of the major
stockholders; (5) Cinergy would tender half of its shares of Convergent in the
offer and contribute the other half to Parent, in accordance with the terms of a
subscription and contribution agreement; and (6) changes would be

                                       13
<PAGE>
required in the employment agreements for Convergent's executive officers. The
board was further advised that Cinergy was prepared to commit to the revised
proposal.

    Based upon the revised proposal, during the morning meeting on October 13,
2000, Morgan Stanley reviewed in detail with the board its updated fairness
opinion and advised the board that it was prepared to deliver its fairness
opinion that, as of October 13, 2000, and subject to and based upon the various
considerations set forth in its opinion, the cash consideration to be received
by holders of Convergent common stock was fair, from a financial point of view,
to the holders of Convergent common stock. In the course of the meeting, InSight
informed the Board that (1) it was willing to commit to the proposal at the
price of $8.00 per share, (2) the venture funds managed by Goldman Sachs had
indicated to InSight that they would similarly be willing to commit to the
proposal, and (3) certain other significant venture capital investors were not
willing to commit to the proposal.

    The special committee met separately later on the same day, after the market
had closed and was updated on the status of the final negotiations and the
resolution of open issues. At that time, Morgan Stanley again reviewed its
updated fairness analysis and reaffirmed its opinion to the special committee
and orally delivered its opinion that the cash consideration to be received in
our offer and the merger were fair to Convergent's stockholders from a financial
point of view. Thereafter, following further discussion, the special committee
determined that the proposed merger agreement, tender offer and merger were fair
to, advisable and in the best interests of, Convergent and its stockholders. The
special committee recommended that Convergent's board of directors approve the
transactions contemplated by the merger agreement and the voting agreement, and
recommend to the stockholders that they accept the tender offer, tender their
shares to us and adopt the merger agreement. At such time, the special committee
also directed the advisors to finalize the documents. Shortly thereafter, Morgan
Stanley delivered its written fairness opinion to the special committee.

    Convergent's board of directors reconvened immediately following the meeting
of the special committee. After considerable discussion, and after having
received the recommendation of the special committee, the board determined that
the proposed merger agreement, tender offer, merger and related transactions
were fair to, advisable and in the best interests of, Convergent and its
stockholders.

    During the night of October 13, 2000,

    - we, our Parent, STC and Convergent executed the merger agreement;

    - we, the management investors and Cinergy executed the voting agreement;
      and

    - we, the major stockholders and Cinergy executed the tender and voting
      agreement.

    On October 27, 2000, we commenced our offer.

2.  PURPOSES, ALTERNATIVES, EFFECTS AND PLANS.

    PURPOSES OF OUR OFFER.  The purpose of our offer and the merger is for our
Parent to acquire control of, and the entire equity interest in, Convergent. Our
offer, as the first step in the acquisition of Convergent, is intended to
facilitate the acquisition of all outstanding shares of Convergent. The purpose
of the merger is to acquire all of the outstanding common stock not purchased
pursuant to our offer or otherwise. If, after consummation of our offer, we own
at least 90% of the shares then outstanding, we will be able to cause the merger
to occur without holding a meeting of Convergent's stockholders to adopt the
merger agreement and without the affirmative vote of Convergent's other
stockholders. If, however, after consummation of our offer, we own less than 90%
of the then-outstanding shares but our Minimum Condition has been satisfied, we
will have sufficient voting power to cause the approval and adoption of the
merger without the affirmative vote of any other stockholder.

                                       14
<PAGE>
    ALTERNATIVES.  Convergent believes that the proposed transaction represents
the best available means to acquire adequate working capital. Management
considers the prospects for raising capital in a secondary public offering less
attractive because the decline in the price for Convergent's stock following its
initial public offering and the general decline in the systems integration and
Internet consulting industries would adversely affect Convergent's ability to
obtain the best possible price from the public. Additionally, although
management continues to explore joint ventures and other business relationships
with strategic partners, including Cinergy, such alternatives do not offer the
potential for access to the same amount of capital that a merger with our Parent
would provide.


    EFFECTS OF OUR OFFER.  As a result of our offer and the merger, the entire
equity interest in Convergent will be beneficially owned by STC, Cinergy and the
management investors through their ownership of our Parent. The stockholders of
Convergent will no longer have any interest in, and will not be stockholders of,
Convergent. The public stockholders of Convergent will have the right to receive
$8.00 in cash, without interest, for each share of Convergent common stock held
(other than shares of Convergent common stock for which appraisal rights have
been perfected).


    To the extent that the management investors and Cinergy receive shares of
our Parent's common stock for their shares of Convergent common stock, they will
have the ability to benefit from any corporate opportunities that may be pursued
by Convergent in the future. However, to the extent that the management
investors receive shares of our Parent for their shares of Convergent common
stock, they will also bear the risk of any decreases in the value of Convergent.
See "The Tender Offer--Merger Agreement; Subscription and Contribution
Agreement; Tender and Voting Agreement; Voting Agreement; Exclusivity Agreement;
Nondisclosure Agreement; Employment Agreements."

    In addition, after the merger, Convergent will no longer be subject to the
reporting requirements of the Exchange Act, which will allow Convergent to
eliminate the time devoted by its management and other employees to matters
which relate exclusively to Convergent being a publicly held company.
Convergent's officers, directors and the owners of more than 10% of the shares
of Convergent will no longer be subject to reporting and the short-swing profit
provisions of Section 16 of the Exchange Act.

    An equity investment in our Parent following the merger will involve
substantial risk resulting from the limited liquidity of the investment and the
leverage resulting from Convergent's existing leverage and any other
indebtedness required to fund the capital expenditures and acquisitions
necessary to execute Convergent's business strategy. Nonetheless, if Convergent
successfully executes its business strategy, the value of an equity investment
in our Parent could be considerably greater than the original cost of the
investment.

    Depending upon the number of shares purchased pursuant to our offer, the
Convergent common stock may no longer meet the standards for continued listing
on the Nasdaq National Market. According to Nasdaq's published guidelines, the
shares would not be eligible to be included for listing if, among other things,
the number of shares that are not held directly or indirectly by any officer or
director of Convergent and by any other person who is the beneficial owner of
more than 10% of the total shares outstanding is less than 750,000, or the
number of holders of shares falls below 400. If, as a result of the purchase of
shares pursuant to our offer, the merger, the merger agreement or otherwise, the
Convergent common stock no longer meet the requirements of the Nasdaq National
Market for continued listing, the listing of the shares will be discontinued. If
that happens, the market for the shares would be adversely affected. If the
shares were no longer eligible for listing on the Nasdaq National Market,
quotations might still be available from other sources. The extent of the public
market for the shares and the availability of quotations would, however, depend
upon the number of stockholders remaining at the time, the interest in
maintaining a market in the shares on the part of securities firms, the possible
termination of registration of the shares under the Exchange Act as described
below and other factors. Assuming we acquire the requisite number of shares to
effect a

                                       15
<PAGE>
delisting of the shares, we intend to cause the delisting of the shares from
Nasdaq following consummation of our offer.

    PLANS FOR CONVERGENT.  Upon completion of our offer, we intend to effect the
merger in accordance with the terms and conditions of the merger agreement.

    The merger agreement provides that, effective upon the consummation of our
offer, Convergent will take such action required to cause persons nominated by
us to constitute the number of directors of Convergent equal to our pro rata
ownership of Convergent.

    Except as otherwise described in this document and except for the
transactions contemplated by the merger agreement, we have no current plans or
proposals which relate to or would result in: (1) an extraordinary corporate
transaction, such as a merger, reorganization or liquidation involving
Convergent; (2) a sale or transfer of a material amount of assets of Convergent;
(3) any change in the management or any change in any material term of the
employment contract of any executive officer; or (4) any other material change
in Convergent's corporate structure or business.

    Nevertheless, we may initiate a review of Convergent and its assets,
corporate structure, capitalization, operations, properties, policies,
management and personnel to determine what changes, if any, would be desirable
following the merger in order best to organize and coordinate the activities of
Convergent and our Parent and its stockholders. Furthermore, in connection with
our ongoing review of Convergent's long term strategy, we may, in the future,
consider the disposition or acquisition of material assets, alliances, joint
ventures, other forms of cooperation with third parties or other extraordinary
transactions affecting Convergent or its operations.

3. REASONS AND RECOMMENDATIONS OF THE SPECIAL COMMITTEE AND THE BOARD OF
   DIRECTORS OF CONVERGENT; FAIRNESS OF THE TRANSACTION.


    The following information (other than information concerning us, our Parent
or STC has been provided to us by Convergent):


    REASONS OF THE SPECIAL COMMITTEE AND THE BOARD OF DIRECTORS OF
CONVERGENT.  The board of directors formed a special committee to review,
negotiate and evaluate the proposed transactions because it appeared that the
management directors would have a significant interest in the proposed
transaction to the extent that they held Convergent stock and their retention as
officers of Convergent would be part of the negotiations. The special committee
(comprised of the three non-employee directors) met and had discussions on
several occasions between September 24, 2000 and October 13, 2000 to consider
developments relating to the proposed transaction. The special committee was
advised during its deliberations by its financial advisor, Morgan Stanley, and
was advised by its legal counsel, O'Sullivan Graev & Karabell. After
considerable discussion and deliberation, at a meeting held on October 13, 2000,
the special committee determined that the merger agreement, our offer, the
merger and the other transactions contemplated by the merger agreement were fair
to, and in the best interests of, the stockholders of Convergent and recommended
that Convergent's board of directors approve the merger agreement.

    Following the unanimous recommendation of the special committee, the board
unanimously approved the merger agreement, our offer, the merger and the
transactions contemplated by the merger agreement, and recommended that
Convergent's stockholders tender their shares pursuant to the offer and adopt
the merger agreement. In connection with each of their unanimous
recommendations, the special committee and the board each reviewed and adopted
the analyses, findings and opinion of the special committee's financial advisor,
Morgan Stanley. Morgan Stanley delivered its opinion that, as of October 13,
2000, and subject to and based on the various considerations set forth in its
opinion the cash consideration to be paid pursuant to the merger agreement was
fair from a financial point of view to the holders of Convergent common stock.

                                       16
<PAGE>
    The special committee is unaware of any developments since its meeting on
October 13, 2000, that would affect its determination that the merger agreement,
our offer, the merger and the transactions contemplated by the merger agreement
are fair to, advisable and in the best interests of, Convergent's stockholders.
Based on the foregoing, the board also determined that the merger agreement, our
offer, the merger and the transactions contemplated thereby are fair to, and in
the best interests of, Convergent's stockholders.

    The material factors that the special committee evaluated in connection with
our offer and the merger are described below. Except as noted below, the special
committee considered each of the following factors to be positive factors
supporting its determination that the merger agreement, our offer, the merger
and the transactions contemplated thereby are fair to, and in the best interests
of, Convergent's stockholders.

    - Morgan Stanley's oral opinion was delivered to the special committee on
      October 13, 2000, that, subject to and based upon the various
      considerations set forth in its opinion, the cash consideration of $8.00
      per share of Convergent common stock to be received by the Convergent
      stockholders in our offer and the merger pursuant to the merger agreement
      was fair to such holders from a financial point of view. The full text of
      Morgan Stanley's written opinion sets forth the assumptions made, the
      matters considered and the limitations on the review undertaken in
      connection with the opinion, and is attached to this document as Annex A
      and is incorporated herein by reference. Convergent's stockholders are
      urged to and should read the Morgan Stanley opinion in its entirety, a
      copy of which is attached to this document as Annex A. See "Special
      Factors--Reports, Opinions, Appraisals and Negotiations."

    - The special committee considered the possibility that we would withdraw
      our bid if our proposal was used to attempt to generate higher bids from
      third parties and, based on advice from Morgan Stanley, the special
      committee determined that, despite the fact that no auction had been
      concluded, the $8.00 price per share to be paid by us in our offer and the
      merger likely exceeds the consideration that holders of Convergent's
      common stock could reasonably expect to receive in a transaction with
      another party.

    - In addition, through the negotiation of the merger agreement the special
      committee was able to reduce significantly the amount of the break-up fee
      and the expenses associated with certain terminations of the merger
      agreement, as well as eliminate the restrictions on solicitation of
      competing bids, which the special committee believes would facilitate the
      creation of competing bids. The special committee noted that members of
      Convergent's management believed that Convergent's August 2000 initial
      public offering had not been as successful as originally hoped, and that
      the recent decline of stock values in the technology, consulting and
      systems integration industries, and the decline in Convergent's stock
      price in particular, made access to the public markets as a source of
      capital less attractive to Convergent and that Convergent would likely
      have better access to the capital necessary to fund its growth as a
      private company if it were controlled by a party such as STC, with better
      access to public and private capital.

    - Specifically, the special committee believes that the termination fee and
      expense reimbursement obligations would not have the effect of
      unreasonably discouraging competing bids and, subject to the satisfaction
      of specified conditions set forth in the merger agreement, the board is
      permitted to withdraw or modify its recommendation to the stockholders
      regarding the merger and enter into an agreement with respect to a more
      favorable transaction with a third party, should such a "Superior
      Proposal" become available prior to the consummation of the offer. In
      addition, Convergent indicated in its press release announcing the merger
      agreement's execution that Convergent may respond to unsolicited proposals
      from alternative bidders. See "The Tender Offer--Merger Agreement;
      Subscription and Contribution Agreement; Tender and Voting

                                       17
<PAGE>
      Agreement; Voting Agreement; Exclusivity Agreement; Nondisclosure
      Agreement; Employment Agreements."

    - Based in part on the declining price of Convergent's common stock, the
      negative change on the systems integration and internet consulting
      industries in general, and advice from Morgan Stanley that, despite the
      fact that no auction had been conducted and based upon Morgan Stanley's
      experience, the group of potential bidders for Convergent was relatively
      small, the special committee believed that it was unlikely that another
      bidder would make a definitive proposal that would result in a transaction
      which would provide greater value to Convergent's stockholders. This
      belief has now been reinforced by the fact that no other party has come
      forward to express interest in an acquisition of Convergent since the
      execution of the merger agreement and the issuance of Convergent's press
      release announcing the transaction.

    - The merger agreement requires that there have been tendered and not
      withdrawn that number of shares which, when taken together with the shares
      beneficially owned by STC, our Parent and us (including the shares to be
      contributed to our Parent pursuant to the subscription and contribution
      agreement), constitute at least a majority of the shares of common stock
      outstanding on a fully diluted basis. The special committee also
      considered the support of affiliates of InSight Capital Partners of the
      tender offer at the board meeting of October 13, 2000, as well as the fact
      that the Goldman Sachs affiliated venture funds and Cinergy had agreed to
      tender their shares in the offer pursuant to the tender and voting
      agreement and, therefore, were supportive of the offer.

    - On October 13, 2000, prior to the announcement of the merger agreement,
      Convergent's common stock on the Nasdaq National Market closed at $4.72
      per share and, therefore, the $8.00 per share price to be paid pursuant to
      our offer represented approximately a 69% premium. Morgan Stanley also
      informed the board that the $8.00 per share to be received by the
      stockholders in our offer and the merger represented premiums ranging from
      approximately 14% to 69% when compared to Convergent's stock price over
      specified pre-announcement trading periods.

    - The merger agreement does not condition our obligations to consummate the
      merger on our or our Parent's ability to obtain financing for the merger.
      Each of STC, our Parent and us has represented in the merger agreement
      that one of such entities will have available funds sufficient to purchase
      all of the outstanding shares of Convergent on a fully diluted basis at
      our offer price and to pay all fees and expenses of our Parent and us in
      connection with the transactions contemplated by the merger agreement.

    - If the merger is consummated, stockholders who have not tendered their
      shares may have the right under Delaware law to dissent from the merger
      and demand appraisal of, and to receive payment in cash equal to the fair
      value of, their shares. Stockholders who perfect appraisal rights by
      complying with the procedures set forth in Section 262 of the Delaware
      General Corporation Law will be entitled to an appraisal by the Delaware
      Court of Chancery of the fair value of the shares. The fair value of the
      shares will be determined as exclusive of any element of value arising
      from the accomplishment or expectation of the merger. In addition,
      dissenting stockholders may be entitled to receive payment of a fair rate
      of interest on the amount determined to be the fair value of their shares,
      interest will be computed from the date Convergent is obligated to pay the
      award to the dissenting stockholders through the date of payment.

    Potentially negative factors considered by the special committee were as
follows:

    - The special committee considered that our Parent has given members of
      Convergent's management an opportunity to contribute their equity
      investments in Convergent for an

                                       18
<PAGE>
      investment in our Parent. As a result, the members of Convergent's
      management will own shares of our Parent. The special committee considered
      that the contribution of a substantial portion of current equity
      investment in Convergent would indicate a level of confidence in
      Convergent's prospects that might be inconsistent with the special
      committee's assessment of the risks associated with Convergent's future.

    - The special committee considered that, under the merger agreement, members
      of Convergent's management would continue as officers of the surviving
      corporation and that their existing options of Convergent would be
      converted on a one-for-one basis for options of our Parent. In the board's
      first meeting on October 13, 2000, it was reported that management would
      enter into amended employment agreements with Convergent. Those employment
      agreements contain new benefits to management, including stock repurchase
      agreements, options to purchase shares in our Parent at a per share price
      of $8.00, severance benefits, and, in Mr. Montgomery's case, a $500,000
      payment for termination of his prior employment agreement and the
      discretion to allocate no less than 25% of any over-allotment options in
      connection with any future underwritten public offering of shares of our
      Parent's common stock.

    In view of the variety of factors considered in connection with its
evaluation of the merger agreement, the special committee found it impracticable
to, and did not, quantify, rank or otherwise assign relative weights to the
factors considered or determine that any factor was of particular importance in
reaching its determination that the merger is fair to, advisable and in the best
interests of, the public stockholders of Convergent. Rather, the special
committee viewed its recommendations as being based upon its judgment, in light
of the totality of the information presented and considered, of the overall
effect of the merger and the transactions contemplated by the merger agreement
on the stockholders compared to any alternative transaction and the likely
effect of rejecting the merger proposal. In arriving at its determination that
our offer, the merger, the merger agreement and the transactions contemplated
thereby were fair to, advisable and in the best interests of, Convergent and all
of its stockholders, the special committee did not consider the net book value,
the liquidation value or the going concern value of Convergent, as the special
committee did not deem these factors relevant to its determination.

    FAIRNESS OF THE TRANSACTION AND RECOMMENDATIONS OF THE SPECIAL COMMITTEE AND
THE BOARD OF DIRECTORS OF CONVERGENT.  The special committee believes that the
procedure that was followed in determining the purchase price to be paid to the
stockholders of Convergent was fair to, and in the best interests of, all
stockholders of Convergent. Convergent's five-person board (of which two
individuals are members of management), appointed as members of the special
committee the three non-employee directors and granted the special committee
exclusive authority on behalf of the board to review, evaluate and negotiate the
proposed transactions. The merger agreement negotiated by the special committee
and its financial and legal advisors contains provisions which enable
Convergent's board of directors to withdraw or modify its recommendation to
Convergent's stockholders regarding our offer and the merger and to enter into
an agreement with respect to a more favorable transaction with a third party.
The merger agreement also contains provisions (without which the special
committee believes we would not have entered into the merger agreement) imposing
upon Convergent termination fee and expense reimbursement obligations that, in
the view of the special committee, are reasonable and would not have the effect
of unreasonably discouraging competing bids.

    Although the merger agreement requires Convergent to notify our Parent of
the existence of any proposal, discussion, negotiation or inquiry which could
reasonably be expected to lead to a superior proposal, Convergent is not
prohibited from entering into negotiations with other perspective buyers. In
addition, Convergent's stockholders may decide not to tender their shares in our
offer and dissent from the merger and be paid cash for the fair value of their
shares under Delaware law. The merger is structured to require the tender of
that number of shares which, when taken together with the shares, if any,
beneficially owned by our Parent, represent more than a majority of the
outstanding shares of

                                       19
<PAGE>
Convergent's common stock on a fully diluted basis. The special committee
believes, as of the date of this offer and for this and the reasons set forth
below, that the merger is procedurally fair to the Convergent's stockholders.


    The special committee believes that the merger is procedurally and
substantively fair to all of Convergent's stockholders because (1) the special
committee (comprised of directors who are not members of management) was
authorized to review, evaluate and negotiate the proposed merger; (2) Morgan
Stanley, a financial advisor unaffiliated to Schlumberger, STC, Parent or us,
was retained to advise the special committee and render an opinion as to the
fairness to the holders of Convergent common stock of the cash consideration to
be received in our offer and the merger from a financial point of view; (3) the
merger agreement allows the board to withdraw its recommendation to the holders
of Convergent common stock and does not prohibit Convergent from entering into
an alternative transaction; (4) the merger requires the tender by holders of
Convergent common stock, which when taken together with the shares of
Convergent's common stock, if any beneficially owned by us, our Parent and STC,
represent more than a majority of the outstanding shares on a fully diluted
basis; and (5) all of the non-employee directors approved the merger.


    The special committee unanimously determined that our offer, the merger, the
merger agreement and the transactions contemplated thereby were fair to,
advisable and in the best interests of, Convergent and all of its stockholders
and recommended that Convergent's board of directors approve the merger
agreement, our offer, the merger and the transactions contemplated by the merger
agreement and that Convergent's board of directors recommend to the stockholders
of Convergent to accept our offer, to tender their shares pursuant to our offer
and to adopt the merger agreement. The board approved the merger agreement, our
offer, the merger and the other transactions contemplated hereby late in the day
on October 13, 2000, after the market had closed, and has confirmed, as of the
date of this offer, that the merger is fair to, advisable and in the best
interests of, all of the stockholders of Convergent.

    All of the directors of Convergent, other than the members of the special
committee, may be considered to have an interest in our offer and the merger.
Accordingly, the board based its determination that the terms of our offer are
fair to the stockholders upon the conclusions of the special committee described
above, the Morgan Stanley opinion and the other factors described above in the
discussion of the reasons of the special committee.


4. THE POSITION OF CONVERGENT, US, OUR PARENT, STC, SCHLUMBERGER AND THE SENIOR
   MANAGEMENT AS TO THE FAIRNESS OF OUR OFFER AND THE MERGER TO THE PUBLIC
   STOCKHOLDERS.



    Rule 13e-3 of the Exchange Act governs "going-private" transactions by
issuers and their affiliates. Accordingly, in compliance with Rule 13e-3, we,
our Parent, STC, Schlumberger, Convergent and the management investors who are
filing persons hereto, whom we refer to as the senior management, may be
required to consider the fairness of our offer and the merger to the public
stockholders.



    We, our Parent, STC, Schlumberger, Convergent and the senior management
believe our offer and the merger to be substantively and procedurally fair to
the public stockholders who are not affiliates of Convergent. We, our Parent,
STC, Schlumberger, Convergent and the senior management have considered the
following factors:


    - The fact that the board of directors and the special committee of the
      board concluded that our offer and the merger are fair to, advisable and
      in the best interests of, Convergent.

    - The historical and projected financial performance of Convergent and its
      financial results.

    - The per share amount represents approximately a 69% premium over the
      closing price for the shares on October 13, 2000, the last full trading
      day prior to announcement of the $8.00 offer.

                                       20
<PAGE>
    - Our offer is an all cash offer for all of the outstanding shares and the
      unaffiliated public stockholders can accept or reject our offer.

    - The ability of unaffiliated public stockholders who do not tender their
      shares and object to the merger to obtain "fair value" for their shares if
      they exercise and perfect their appraisal rights under the Delaware
      General Corporation Law.

    - Our offer is not subject to a financing condition.

    - Our offer provides the unaffiliated public stockholders who are
      considering selling their shares with the opportunity to sell their shares
      at the per share amount without incurring the transaction costs typically
      associated with market sales.


    - The terms of the merger agreement were determined through arm's-length
      negotiations between the special committee and its legal and financial
      advisors, on the one hand, and representatives of us, our Parent, STC and
      Schlumberger, on the other hand, and provide for our offer to allow
      unaffiliated public stockholders to receive payment for their shares on an
      accelerated basis. These terms were negotiated before we, our Parent or
      STC beneficially owned any shares.



    We, our Parent, STC, Schlumberger, Convergent and the senior management have
reviewed the factors considered by the special committee and Convergent's board
of directors in support of its decision as described above, and had no basis to
question their consideration of or reliance on these factors. In view of the
variety of factors considered with their evaluation of our offer and the merger,
we, our Parent, STC, Schlumberger, Convergent and the senior management found it
impracticable to, and did not, quantify, rank or otherwise assign relative
weights to the factors considered or determine that any factor was of particular
importance in reaching their determination that our offer and the merger are
fair to, advisable and in the best interests of the unaffiliated public
stockholders of Convergent. Rather, we, our Parent, STC, Schlumberger,
Convergent and the senior management viewed their position as being based upon
their judgement, in light of the totality of the information presented and
considered, of the overall effect of the merger and the transactions
contemplated by the merger agreement on the unaffiliated public stockholders
compared to any alternative transaction and the likely effect of rejecting the
merger proposal.


5.  INTERESTS OF CERTAIN PERSONS IN OUR OFFER AND THE MERGER.

    In considering the recommendations of the board of directors of Convergent
and the special committee with respect to the merger, you should be aware that
Convergent's officers, directors and the management investors have interests in
connection with our offer and the Merger which may present them with actual or
potential conflicts of interest as described below. The special committee was
aware of these interests and considered them among the other matters described
below and in "Special Factors--Reasons and Recommendations of the Special
Committee and the Board of Directors of Convergent; Fairness of the
Transaction."

    The management investors together own approximately 29.7% of Convergent's
shares and Cinergy owns approximately 4.5% of Convergent's shares on a fully

    TRANSACTIONS WITH GLENN MONTGOMERY.  On August 13, 1999, Convergent extended
a $2,000,000 loan to Glenn E. Montgomery, Jr., evidenced by a promissory note.
The interest rate on the loan is 5.9% per annum, and Mr. Montgomery is required
to make payments of principal and interest to Convergent in four equal
installments of $652,685.27 on or before each of July 1, 2003, January 1, 2004,
July 1, 2004 and August 13, 2004. Mr. Montgomery may prepay the outstanding
principal and accrued interest on the loan at any time without penalty.
Mr. Montgomery will repay this loan pursuant to the terms of his new employment
agreement upon the consummation of the merger.

    The loan to Mr. Montgomery is non-recourse. To secure the loan,
Mr. Montgomery executed a stock pledge agreement whereby he pledged to
Convergent all shares of the common stock of Convergent then owned by him. In
addition, Mr. Montgomery's obligations under the promissory note were initially
guaranteed on a non-recourse basis by GMJM Stock Partnership, Ltd. ("GMJM").
GMJM's obligations under the guaranty are secured by a pledge to Convergent of
all shares of the common stock owned by GMJM. The GMJM guaranty and pledge were
released in January 2000 in connection with the sale of the shares owned by
GMJM. In connection with the release of the GMJM guaranty and pledge,
Mr. Montgomery pledged additional shares of Convergent's common stock that he
acquired subsequent to the date of his original pledge.

    Between January 15, 2000 and February 14, 2000, Mr. Montgomery sold 755,420
shares of preferred and common stock in private transactions to three separate
investor groups. Total aggregate consideration for the transactions amounted to
approximately $6.0 million, or approximately $8.00 per share.

    1999/2000 ISSUANCE OF RESTRICTED STOCK TO CERTAIN DIRECTORS.  On
October 29, 1999 Convergent issued 377,710 shares of common stock each to Robert
Sharpe and John W. Blend III, members of its board of directors. The shares were
subject to vesting at the rate of 47,213.5 shares per calendar quarter,
effective on the last day of such quarter, commencing September 30, 1999, as
well as forfeiture in the event that Mr. Sharpe or Mr. Blend's service as a
director terminated. In connection with the tender offer, the board resolved on
October 13, 2000 to accelerate the vesting of these shares and waive
restrictions on transfer contained in the restricted stock agreements whereby
the shares were issued to Mr. Sharpe and Mr. Blend.

    THE 1999 RECAPITALIZATION.  The following information was provided to us by
Convergent.

    On August 13, 1999, Convergent consummated a recapitalization pursuant to an
agreement among Convergent, a number of its then existing stockholders and
investors led by InSight, including UBS Capital II LLC and the Goldman Sachs
managed venture funds. In connection with the recapitalization, these investors
acquired approximately a 63% controlling interest in Convergent through the
purchase of shares of a new series of Convergent's voting convertible
participating preferred stock for a total purchase price of approximately
$45.5 million. As a part of the recapitalization:

    - Convergent entered into a $25.0 million revolving line of credit with
      Fleet National Bank, of which $22.0 million was borrowed in order to
      finance the recapitalization;

    - all shares of Convergent's then outstanding preferred stock and all shares
      of common stock owned by Convergent's two largest non-employee
      stockholders were purchased for a total purchase price of approximately
      $44.3 million;

    - Convergent's employee stockholders, including several management
      investors, received cash payments totaling $11.8 million for the sale of a
      portion of their equity interest in Convergent;


    - Convergent made cash payments totaling approximately $5.4 million to
      members of Convergent's senior management in connection with the
      termination of their then effective employment agreements, as finance fees
      in connection with the recapitalization and to satisfy deferred
      compensation obligations to those members of senior management;


                                       24
<PAGE>
    - Convergent issued 10,516,424 shares of common stock and options to
      purchase 694,506 shares of its common stock at an exercise price of $0.092
      per share, to employees, including several management investors, in
      consideration for their continued employment with Convergent; and

    - Convergent loaned $2.0 million to Glenn Montgomery.


    Under the recapitalization agreement, Convergent agreed to indemnify the
investors, in the form of cash, additional shares of its stock, or a combination
of both, for breaches of representations, warranties and covenants Convergent
made to them in connection with their purchase of its capital stock (including
representations and warranties regarding Convergent's financial condition, its
liabilities and its client contracts), up to a maximum of $1.5 million in cash
and $3.0 million in preferred stock, valued at $1.08 per share. The majority of
the representations and warranties under the recapitalization agreement survive
for one year. The obligation to indemnify the investors against environmental
claims remains in effect until the seventh anniversary of the closing of the
recapitalization. The obligations to indemnify the investors against tax-related
and ERISA claims remain in effect until the expiration of all applicable
statutes of limitation. The obligation to indemnify the investors against claims
made in connection with certain representations and warranties relating to
certain fundamental corporate matters, such as Convergent's organization, its
subsidiaries, its outstanding stock and corporate approvals, remains in effect
indefinitely. Also in connection with the recapitalization, Convergent's
continuing stockholders agreed to elect two designees of the investors (John W.
Blend III and Jerry Murdock) to serve on the board of directors. This obligation
to elect the designees of the investors terminated upon Convergent's initial
public offering.

following the merger the following individuals and entities will beneficially
own the number of shares of our Parent's common stock shown in the following
table, which shares will represent all of the outstanding shares of Parent

    MERGER CONSIDERATION ANALYSIS.  Morgan Stanley reviewed the cash
consideration to be received by Convergent stockholders in connection with our
offer and the merger. As part of this analysis, Morgan Stanley also calculated

Convergent's common stock over various time periods ending on October 11, 2000.
Based on the all-cash offer of $8 per share of Convergent's common stock, Morgan
Stanley calculated the premium to be 65% relative to the price of shares of
Convergent's common stock as of October 11, 2000. Additionally, relative to the
average closing price of shares of Convergent's common stock for the 5-trading
day, 10-trading day and 30-trading day periods ending on October 11, 2000,
respectively, Morgan Stanley calculated the premium to be 65%, 69% and 69%,
respectively. Finally, relative to the average price from the August 1, 2000
initial public offering to October 11, 2000 and the price of the August 1, 2000

- Proxicom, Inc.                       - Viant Corporation
</TABLE>

    Morgan Stanley then reviewed publicly available information to compare
financial information and public market multiples of these comparable public
companies to Convergent's public market multiples. The comparison included:

    - aggregate value to last twelve months' revenue;

    - aggregate value to 2000 estimated revenue;

    - aggregate value to 2001 estimated revenue;

    - stock price to 2001 estimated net income per share; and

    - stock price to the ratio of 2001 estimated net income per share to the
      estimated long term growth rate of earnings.

    The following table reflects the results of the analysis, as compared to the
multiples for Convergent:

</TABLE>

    Applying a range of multiples derived from the comparable public companies
analysis, Morgan Stanley calculated a range of implied equity values per share
of Convergent with respect to Convergent's:

    - aggregate value to last twelve months revenue;

    - aggregate value to 2000 estimated revenue;

    - aggregate value to 2001 estimated revenue;

    - stock price to 2001 estimated net income per share; and

    - stock price to 2001 estimated net income per share to the estimated long
      term growth rate of earnings.

    Based on this analysis, Morgan Stanley derived a range of implied equity
values per share of Convergent of $3.00 to $5.00.

    No company utilized in the comparable public companies analysis is identical
to Convergent. Accordingly, an analysis of the results necessarily involves
complex considerations and judgments concerning differences in financial and
operating characteristics of Convergent and other factors that could affect the
public trading value of the companies to which Convergent is being compared. In
evaluating the comparable companies, Morgan Stanley made judgments and
assumptions with regard to industry performance, general business, economic,
market and financial conditions and other matters, many of which are beyond the
control of Convergent, like the impact of competition on Convergent and the
industry generally, industry growth and the absence of any adverse material
change in the financial conditions and prospects of Convergent or the industry
or in the financial markets in general. Mathematical analysis, such as
determining the mean, median or average, is not in itself a meaningful method of
using comparable company data.

    PRECEDENT TRANSACTIONS ANALYSIS.  Using publicly available information,
Morgan Stanley considered 18 announced or completed transactions in the
technology services industry comparable in respects to the tender offer and the
merger which we refer to collectively as the precedent transactions. These
precedent transactions included:

    - Diamond Technology Partners' acquisition of Cluster Consulting;

    - General Electric's acquisition of Smallworldwide;

    - CommerceOne's acquisition of AppNet;

    - Eltrax Systems' acquisition of Cereus Technology Partners;

    - Computer Sciences Corporation's acquisition of Policy Management Systems;

    - PSINet's acquisition of Metamor Worldwide;

    - Whittman-Hart's acquisition of USWeb/CKS;

    - iXL Enterprises' acquisition of Tessera Enterprise Systems;

    - Lucent Technologies' acquisition of International Network Services;

                                       29
<PAGE>
    - Razorfish's acquisition of I-Cube;

    - USWeb/CKS' acquisition of Mitchell Madison Group;

    - I-Cube's acquisition of Conduit;

    - AnswerThink Consulting Group's acquisition of Think New Ideas;

    - Welsh Carson Anderson & Stowe's acquisition of Banctec;

    - Iron Mountain, Inc.'s acquisition of Data Base, Inc.;

    - Computer Associates International Inc.'s acquisition of Computer
      Management Systems, Inc.;

    - Affiliated Computer Services' acquisition of BRC Holdings, Inc.; and

    - IAT Multimedia, Inc.'s acquisition of ATEC Group.

    Morgan Stanley then reviewed publicly available information to compare
financial information and market statistics of the precedent transactions to the
merger. The comparison included:

    - percentage premium to unaffected market price; and

    - aggregate value to last twelve month revenue

    The following table reflects the results of the analysis, as compared to the
multiples for Convergent:

<TABLE>

Precedent Transactions..................             42-60              3.2x-5.1x
</TABLE>

    Based on an analysis of the corresponding premium to unaffected market price
and aggregate value to last twelve month revenue, Morgan Stanley calculated per
share transaction values for Convergent ranging from $7.00 to $9.00.

    No transaction utilized as a comparison in the precedent transactions
analysis is identical to the tender offer or the merger, and, accordingly, an
analysis of the results of the foregoing necessarily involves complex
considerations and judgments concerning differences in financial and operating
characteristics of Convergent and other factors that would affect the
acquisition value of the companies to which it is being compared. In evaluating
the precedent transactions, Morgan Stanley made judgments and assumptions with
regard to industry performance, general business, economic, market and financial
conditions and other matters, many of which are beyond the control of
Convergent, such as the impact of competition on Convergent and the industry
generally, industry growth and the absence of any adverse material change in the
financial conditions and prospects of Convergent or the industry or in the
financial markets in general. Mathematical analysis, such as determining the
mean or median, is not, in itself, a meaningful method of using precedent
transactions data.

    In connection with the review of our offer and the merger by the special
committee, Morgan Stanley performed a variety of financial and comparative
analyses for purposes of delivering its opinion. The preparation of a fairness
opinion is a complex process and is not necessarily susceptible to partial
analysis or summary description. In arriving at its opinion, Morgan Stanley
considered the results of all of its analyses as a whole and did not attribute
any particular weight to any analysis or factor it considered. Furthermore,
Morgan Stanley believes that selecting any portion of its analyses, without
considering all analyses would create an incomplete view of the process
underlying its analyses and opinion. In addition, Morgan Stanley may have given
various analyses and factors more or less weight than other analyses and
factors, and may have deemed various assumptions more or less probable than
other assumptions, so that the ranges of valuations resulting from any
particular analysis described above should not be taken to be Morgan Stanley's
view of the actual value of Convergent.

                                       30
<PAGE>

    In performing its analyses, Morgan Stanley made numerous assumptions with
respect to industry performance, general business and economic conditions and
other matters, many of which are beyond the control of Convergent, us, our
Parent, STC and Schlumberger. Any estimates contained in Morgan Stanley's
analysis are not necessarily indicative of future results or actual values,
which may be significantly more or less favorable than those suggested by the
estimates. The analyses performed were prepared solely as part of Morgan
Stanley's analysis of the fairness from a financial point of view of the cash
consideration to be received by the Convergent stockholders pursuant to our
offer and the merger agreement and were conducted in connection with the
delivery of Morgan Stanley's opinion, dated October 13, 2000, to the special
committee. The analyses do not purport to be appraisals or to reflect the prices
at which the Convergent common stock might actually trade. The cash
consideration pursuant to the merger agreement and other terms of the merger
agreement were determined through arm's length negotiations between Convergent,
us, our Parent, STC and Schlumberger and were approved by the special committee.
Morgan Stanley provided advice to Convergent during such negotiations; however,
Morgan Stanley did not recommend any specific consideration to Convergent or
that any specific consideration constituted the only appropriate consideration
for the tender offer or the merger. In arriving at its opinion, Morgan Stanley
was not authorized to solicit, and did not solicit, interest from any party with
respect to the acquisition, business combination or other extraordinary
transaction involving Convergent. Morgan Stanley's opinion was one of many
factors taken into consideration by the special committee in making its decision
to recommend the merger agreement and the transactions contemplated thereby to
Convergent's board of directors. Consequently, the Morgan Stanley analyses as
described above should not be viewed as determinative of the opinion of the
special committee with respect to value of Convergent or whether the special
committee would have been willing to agree to different consideration.



    Morgan Stanley was retained as financial advisor to the special committee
based upon Morgan Stanley's qualifications, experience and expertise. Morgan
Stanley is an internationally recognized investment banking and advisory firm.
Morgan Stanley, as part of its investment banking and financial advisory
business, is continuously involved in the valuation of business and securities
in connection with mergers and acquisitions, negotiated underwritings,
competitive biddings, secondary distributions of listed and unlisted securities,
private placements and valuations for corporate and other purposes. In the
ordinary course of Morgan Stanley's business, Morgan Stanley or its affiliates
may from time to time hold or trade in the securities or indebtedness of
Convergent, STC or Schlumberger and its affiliates for its own account, the
accounts of investment funds and other clients under the management of Morgan
Stanley or its affiliates and for the account of its customers, and,
accordingly, may at any time hold long or short positions in these securities or
indebtedness.


    Pursuant to the terms of the engagement letter, Morgan Stanley has provided
advisory services in connection with the tender offer and the merger and
Convergent has agreed to pay a customary fee in connection therewith. In
addition, Convergent has also agreed to reimburse Morgan Stanley for its
reasonable expenses incurred in performing its services and to indemnify Morgan
Stanley and its affiliates, their respective directors, officers, agents and
employees and each person, if any, controlling Morgan Stanley or any of its
affiliates against certain liabilities and expenses, including the fees of its
legal counsel and certain liabilities under the federal securities laws, related
to or arising out of Morgan Stanley's engagement and any related transactions.

    The full text of Morgan Stanley's written presentation to the special
committee on October 13, 2000 has been attached as an exhibit to the Schedule TO
we filed with the Securities and Exchange Commission and we incorporated it by
reference. In addition to Annex A to this document, Convergent will make Morgan
Stanley's opinion letter available to any interested Convergent stockholder or a
stockholder's representative who has been designated as an authorized
representative in writing for inspection and copying at Convergent's principal
executive offices.

                                THE TENDER OFFER

1.  TERMS OF OUR OFFER; EXPIRATION DATE.

    Upon the terms and subject to the conditions of our offer (including any
terms and conditions of any extension or amendment), we will accept for payment
and pay for all shares validly tendered (and not withdrawn in accordance with
the procedures set forth in "The Tender Offer--Withdrawal Rights") on or prior
to the "Expiration Date." The "Expiration Date" means 12:00 Midnight, New York
City time, on Monday, November 27, 2000, unless and until we (subject to the
terms and conditions of the merger agreement) extend the period during which our
offer is open, in which case "Expiration Date" will mean the latest time and
date at which our offer, as we have extended it, will expire.

    Our offer is subject to the conditions set forth in "The Tender
Offer--Conditions of Our Offer," including the satisfaction of the Minimum
Condition and the acquiring of material governmental approvals. Subject to the
terms of the merger agreement, we expressly reserve the right to waive any
condition to our offer in whole or in part, in our sole discretion, and also
expressly reserve the right to increase the price per share payable in our offer
and to make any other changes in the terms and conditions of our offer; but,
without the written consent of Convergent, we will not amend or waive the
Minimum Condition. We cannot legally waive material governmental approvals. We
have also agreed that we will not decrease the number of shares sought in our
offer, change the form of or decrease the amount of consideration to be paid,
impose conditions to our offer in addition to those set forth in "The Tender
Offer--Conditions of Our Offer," make any other change in our offer which is
materially adverse to you or extend our offer (except as provided in the merger
agreement).

    The merger agreement provides that we may, without the consent of
Convergent, extend our offer beyond 12:00 Midnight, New York City time, on
Monday November 27, 2000, if, on that date, any of the conditions to our offer,
are not satisfied or waived, until that condition is satisfied or waived (except
that the Minimum Condition may not be waived). We have agreed to extend our
offer from time to time until March 31, 2001 if, and to the extent that, at the
Expiration Date, the conditions to our offer have not been satisfied or waived.
We may extend our offer after the acceptance of shares for a further period of
time by means of a subsequent offering period under Rule 14d-11 under the
Exchange Act, of not more than twenty business days to meet the objective that
there be validly tendered and not withdrawn prior to the Expiration Date (as so
extended) a number of shares which, together with shares then owned by us and
our Parent, represents at least 90% of the outstanding shares. If, during an
extension for this purpose, you have previously tendered your shares, you will
not be able to withdraw your shares. Under no circumstances will interest be
paid on the purchase price for tendered shares, whether or not our offer is
extended.

    We will pay for all shares validly tendered and not withdrawn promptly
following the acceptance of shares for payment pursuant to our offer. Subject to
the rules of the Securities and Exchange Commission and the terms and conditions
of our offer, we also expressly reserve the right to delay payment for shares in
order to comply in whole or in part with applicable laws (any delay will be
effected in compliance with Rule 14e-1(c) under the Exchange Act, which requires
us to pay the consideration offered or to return shares deposited by or on
behalf of stockholders promptly after the termination or withdrawal of our
offer).

    We will, as promptly as practicable, make a public announcement of any
extension, delay, termination, waiver or amendment. If we extend our offer, we
will make the announcement no later than 9:00 a.m., New York City time, on the
next business day after the previously scheduled Expiration Date. Subject to
applicable law (including Rules 14d-4(c), 14d-6(d) and 14e-1 under the Exchange
Act, which require that material changes be promptly disseminated to you in a
manner reasonably designed to inform you of changes) and without limiting the
manner in which we may choose to make any public announcement, we will have no
obligation to publish, advertise or otherwise communicate any public
announcement other than by issuing a press release to Business Wire.

                                       32
<PAGE>
    If we make a material change in the terms of our offer or the information
concerning our offer, or if we waive a material condition of our offer, we will
extend our offer to the extent required by Rules 14d-4(c), 14d-6(d) and 14e-1
under the Exchange Act. If, before the Expiration Date, we decide to increase
the consideration being offered our offer, the increase in the offered
consideration will be applicable to all stockholders whose shares are accepted
for payment pursuant to our offer. If at the time notice of any increase in the
offered consideration being is first published, sent or given, our offer is
scheduled to expire at any time earlier than the period ending on the tenth
business day from and including the date that the notice is first so published,
sent or given, our offer will be extended at least ten business days after that
notice.

    For purposes of our offer, a "business day" means any day other than a
Saturday, a Sunday or a day on which commercial banks in New York City are
permitted by law, rule or regulation to be closed.

    Convergent has provided us mailing labels, security position listings and
any available listing or computer file containing the names and addresses of all
recordholders of the shares. This document and the related Letter of Transmittal
will be mailed to the recordholders whose names appeared on Convergent's
stockholder list and will be furnished, for subsequent transmittal to beneficial
owners of shares, to brokers, dealers, commercial banks, trust companies and
similar persons whose names, or the names of whose nominees, appear on the
stockholder list or, if applicable, who are listed as participants in a clearing
agency's security position listing.

2.  ACCEPTANCE FOR PAYMENT AND PAYMENT FOR SHARES.

    Upon the terms and subject to the conditions of our offer (including, if our
offer is extended or amended, the terms and conditions of any extension or
amendment), we will accept for payment all shares validly tendered (and not
properly withdrawn in accordance with "The Tender Offer--Withdrawal Rights")
prior to the Expiration Date promptly after the occurrence of the Expiration
Date. Additionally, we will pay for all shares validly tendered and not
withdrawn promptly following the acceptance of shares pursuant to our offer.

    In all cases, we will pay for shares tendered and accepted for payment
pursuant to our offer only after timely receipt by our Depositary of (1) the
stock certificates evidencing tendered shares or timely confirmation of a
book-entry transfer of shares into our Depositary's account at The Depository
Trust Company, or DTC, pursuant to the procedures set forth in "The Tender
Offer--Procedures for Accepting Our Offer and Tendering Shares," (2) the Letter
of Transmittal (or a manually signed facsimile of the Letter of Transmittal),
properly completed and duly executed, with any required signature guarantees or
an Agent's Message, in connection with the book-entry transfer and (3) any other
documents required by the Letter of Transmittal. An "Agent's Message" is a
message, transmitted by DTC to, and received by, our Depositary and forming a
part of the book-entry confirmation which states that DTC has received an
express acknowledgment from the participant in DTC tendering the shares that are
the subject of the book-entry confirmation, that the participant has received
and agrees to be bound by the Letter of Transmittal and that we may enforce the
agreement against that participant.

    For purposes of our offer, we will be deemed to have purchased shares which
have been validly tendered and not properly withdrawn if and when we give oral
or written notice to our Depositary of our acceptance for payment of shares
pursuant to our offer. Upon the terms and subject to the conditions of our
offer, payment for the shares will be made by depositing the aggregate purchase
price with our Depositary. UNDER NO CIRCUMSTANCES WILL INTEREST ON THE PURCHASE
PRICE FOR SHARES BE PAID, REGARDLESS OF ANY DELAY IN MAKING PAYMENT.

    If we do not accept tendered shares for payment for any reason pursuant to
the terms and conditions of our offer, or if stock certificates are submitted
evidencing more shares than are tendered, the stock certificates evidencing
unpurchased shares will be returned, without expense to the tendering

                                       33
<PAGE>
stockholder (or, in the case of shares tendered by book-entry transfer into our
Depositary's account at DTC pursuant to the procedure set forth in "The Tender
Offer--Procedures for Accepting Our Offer and Tendering Shares," the shares will
be credited to an account maintained at DTC), as promptly as practicable
following the expiration or termination of our offer.

    We reserve the right to assign, in our sole discretion, any or all of our
rights, interests and obligations contained in the merger agreement to STC or to
any direct or indirect wholly owned subsidiary of STC, but any assignment will
not relieve us of our obligations under our offer and will in no way prejudice
your rights to receive payment for shares validly tendered and accepted for
payment pursuant to our offer.

    If you are a record owner of shares and tender directly to our Depositary,
you will not be obligated to pay brokerage fees or commissions or, except as
provided in Instruction 6 of the Letter of Transmittal, stock transfer taxes
with respect to our purchase of shares pursuant to our offer. Nonetheless, if
you fail to complete and sign the Substitute Form W-9, which is included in the
Letter of Transmittal, you may be subject to a required back-up U.S. federal
income tax withholding of 31% of the gross proceeds payable to you. See "The
Tender Offer--Material Federal Income Tax Consequences."

3.  PROCEDURES FOR ACCEPTING OUR OFFER AND TENDERING SHARES.

    In order for you to validly tender shares pursuant to our offer, the Letter
of Transmittal (or a manually signed facsimile of the Letter of Transmittal),
properly completed and duly executed, together with any required signature
guarantees or, in the case of a book-entry transfer, an Agent's Message, and any
other documents required by the Letter of Transmittal, must be received by our
Depositary at one of its addresses set forth on the back cover of this document
and either (1) the stock certificates evidencing tendered shares must be
received by our Depositary at its address or the shares must be tendered
pursuant to the procedure for book-entry transfer described below and a
book-entry confirmation must be received by our Depositary (including an Agent's
Message if you did not deliver a Letter of Transmittal), in each case prior to
the Expiration Date, or (2) you must comply with the guaranteed delivery
procedures described below.

    THE METHOD OF DELIVERY OF STOCK CERTIFICATES AND ALL OTHER REQUIRED
DOCUMENTS, INCLUDING DELIVERY THROUGH DTC, IS AT YOUR OPTION AND RISK, AND THE
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY OUR DEPOSITARY. IF
DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERTY
INSURED, IS RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO
ENSURE TIMELY DELIVERY.

    BOOK-ENTRY TRANSFER.  Our Depositary will establish an account with respect
to the shares at DTC for purposes of our offer within two business days after
the date of this document. Any financial institution that is a participant in
the system of DTC may make a book-entry delivery of shares by causing DTC to
transfer shares into our Depositary's account at DTC in accordance with DTC's
procedures. However, although delivery of shares may be effected through
book-entry transfer at DTC, the Letter of Transmittal (or a manually signed
facsimile of the Letter of Transmittal), properly completed and duly executed,
together with any required signature guarantees, or an Agent's Message, and any
other required documents, must, in any case, be received by our Depositary at
one of its addresses set forth on the back cover of this document prior to the
Expiration Date, or you must comply with the guaranteed delivery procedure
described below. Delivery of documents to DTC does not constitute delivery to
our Depositary.

    SIGNATURE GUARANTEES.  Signatures on all Letters of Transmittal must be
guaranteed by a firm that is a member of the Security Transfer Agent Medallion
Signature Program, or by any other "eligible guarantor institution," as the term
is defined in Rule 17Ad-15 under the Exchange Act, except in cases where shares
are tendered (1) by a registered holder of shares who has not completed either
the box

                                       34
<PAGE>
entitled "Special Payment Instructions" or the box entitled "Special Delivery
Instructions" on the Letter of Transmittal or (2) for the account of an eligible
guarantor institution. If a stock certificate is registered in the name of a
person other than the signer of the Letter of Transmittal, or if payment is to
be made, or a stock certificate not accepted for payment or not tendered is to
be returned, to a person other than the registered holder(s), then the stock
certificate must be endorsed or accompanied by appropriate stock powers, in
either case signed exactly as the name(s) of the registered holder(s) appear on
the stock certificate, with the signature(s) on the stock certificate or stock
powers guaranteed by an eligible guarantor institution. See Instructions 1 and 5
of the Letter of Transmittal.

    GUARANTEED DELIVERY.  If you desire to tender shares pursuant to our offer
and the stock certificate(s) evidencing your shares are not immediately
available or you cannot deliver your stock certificate(s) and all other required
documents to our Depositary prior to the Expiration Date, or you cannot complete
the procedure for delivery by book-entry transfer on a timely basis, your shares
may still be tendered, provided that all the following conditions are satisfied:

    - the tender is made by or through an eligible guarantor institution;

    - a properly completed and duly executed Notice of Guaranteed Delivery is
      received prior to the Expiration Date by our Depositary; and

    - the stock certificate(s) (or a book-entry confirmation) evidencing all
      tendered shares, in proper form for transfer, in each case together with
      the Letter of Transmittal (or a manually signed facsimile of the Letter of
      Transmittal), properly completed and duly executed, with any required
      signature guarantees or, in the case of a book-entry transfer, an Agent's
      Message, and any other documents required by the Letter of Transmittal are
      received by our Depositary within three trading days after the date of
      execution of the Notice of Guaranteed Delivery.

    You may deliver your Notice of Guaranteed Delivery by hand or mail or by
facsimile transmission to our Depositary. Your Notice of Guaranteed Delivery
must include a guarantee by an eligible guarantor institution in the form set
forth in the Notice of Guaranteed Delivery.

    In all cases, we will pay for shares tendered and accepted pursuant to our
offer only after timely receipt by our Depositary of the stock certificate(s)
evidencing shares, or a book-entry confirmation of the delivery of shares, and
the Letter of Transmittal (or a manually signed facsimile of the Letter of
Transmittal), properly completed and duly executed, with any required signature
guarantees or, in the case of a book-entry transfer, an Agent's Message, and any
other documents required by the Letter of Transmittal.

    DETERMINATION OF VALIDITY.  We will determine, in our sole discretion, all
questions as to the form of documents and the validity, form, eligibility
(including time of receipt) and acceptance for payment of any tender of shares.
Our determination will be final and binding on all parties. We reserve the
absolute right to reject any and all tenders determined by us not to be in
proper form or the acceptance for payment of which may be unlawful. We also
reserve the absolute right to waive any condition of our offer to the extent
permitted by applicable law and the merger agreement or any defect or
irregularity in the tender of any shares of any particular stockholder, whether
or not similar defects or irregularities are waived in the case of other
stockholders. A TENDER OF SHARES WILL NOT HAVE BEEN VALIDLY MADE UNTIL ALL
DEFECTS AND IRREGULARITIES HAVE BEEN CURED OR WAIVED. NEITHER WE, OUR PARENT,
STC NOR ANY OF STC'S, OUR PARENT'S OR OUR RESPECTIVE AFFILIATES OR ASSIGNS, OUR
DEALER MANAGER, OUR DEPOSITARY, OUR INFORMATION AGENT, OR ANY OTHER PERSON WILL
BE UNDER ANY DUTY TO GIVE NOTIFICATION OF ANY DEFECTS OR IRREGULARITIES IN
TENDERS OR INCUR ANY LIABILITY FOR FAILURE TO GIVE ANY NOTIFICATION. Our
interpretation of the terms and conditions of our offer (including the Letter of
Transmittal and the instructions thereto) will be final and binding

    If you tender your shares pursuant to any of the procedures described above,
it will constitute your acceptance of the terms and conditions of our offer, as
well as your representation and warranty to us

                                       35
<PAGE>
that (1) you have the full power and authority to tender, sell, assign and
transfer the tendered shares (and any and all other shares or other securities
issued or issuable in respect of your shares), and (2) when we accept your
shares for payment, we will acquire good and unencumbered title thereto, free
and clear of all liens, restrictions, charges and encumbrances and not subject
to any adverse claims.

    OUR ACCEPTANCE OF YOUR SHARES PURSUANT TO ANY OF THE PROCEDURES DESCRIBED
ABOVE WILL CONSTITUTE A BINDING AGREEMENT BETWEEN YOU AND US UPON THE TERMS AND
SUBJECT TO THE CONDITIONS OF OUR OFFER.

    APPOINTMENT AS PROXY.  By executing the Letter of Transmittal, you
irrevocably appoint our designees as your agents, attorneys-in-fact and proxies,
each with full power of substitution, in the manner set forth in the Letter of
Transmittal, to the full extent of your rights with respect to the shares you
tender and we accept for payment (and with respect to any and all other shares
or other securities issued or issuable on or after October 27, 2000). These
powers of attorney and proxies will be considered irrevocable and coupled with
an interest in the tendered shares. The appointment will be effective when, and
only to the extent that, we accept your shares for payment. Upon our acceptance
for payment, all prior powers of attorney and proxies given by you with respect
to your shares (and your other shares and securities) will be revoked, without
further action, and no subsequent powers of attorney or proxies may be given nor
any subsequent written consent executed by you (and, if given or executed, will
not be deemed to be effective). Our designees will, with respect to the shares
for which the appointment is effective, be empowered to exercise all of your
voting and other rights as they in their sole discretion may deem proper at any
annual or special meeting of Convergent's stockholders or any adjournment or
postponement of that meeting, by written consent in lieu of any meeting or
otherwise. We reserve the right to require that, in order for shares to be
deemed validly tendered, immediately upon our payment for the shares, we must be
able to exercise full voting rights with respect to the shares (and the other
shares and securities).

4.  WITHDRAWAL RIGHTS.

    Tenders of shares made pursuant to our offer are irrevocable except that
tendered shares may be withdrawn at any time prior to the Expiration Date. If we
extend our offer, are delayed in our acceptance for payment of shares or are
unable to accept shares for payment pursuant to our offer for any reason, then,
without prejudice to our rights under our offer, our Depositary may,
nevertheless, on our behalf, retain tendered shares, and those shares may not be
withdrawn except to the extent that tendering stockholders are entitled to
withdrawal rights as described in this Section 4. Any delay will be by an
extension of our offer to the extent required by law.

    We may, without the consent of Convergent, extend our offer beyond 12:00
Midnight, New York City time, if, on the 60th day from the date of this
document, any of the conditions to our offer, are not satisfied or waived, until
that condition is satisfied or waived (except that the Minimum Condition may not
be waived). We have agreed to extend our offer from time to time until
March 31, 2001 if, and to the extent that, at the Expiration Date, the
conditions to our offer have not been satisfied or waived.

    We may extend our offer after the acceptance of shares for a further period
of time by means of a subsequent offering period under Rule 14d-11 under the
Exchange Act, of not more than twenty business days to meet the objective that
there be validly tendered and not withdrawn prior to the Expiration Date a
number of shares which, together with shares then owned by our Parent and us,
represents at least 90% of the outstanding shares. If, during an extension for
this purpose, you have previously tendered your shares, you will not be able to
withdraw your shares. Under no circumstances will interest be paid on the
purchase price for tendered shares, whether or not our offer is extended.

    For a withdrawal to be effective, a written or facsimile transmission notice
of withdrawal must be timely received by our Depositary at one of its addresses
set forth on the back cover page of this document. Any notice of withdrawal must
specify the name of the person who tendered the shares to be withdrawn, the
number of shares to be withdrawn and the name of the registered holder of the

                                       36
<PAGE>
shares, if different from that of the person who tendered the shares. If stock
certificates evidencing shares to be withdrawn have been delivered or otherwise
identified to our Depositary, then, prior to the physical release of the stock
certificates, the serial numbers shown on the stock certificates must be
submitted to our Depositary and the signature(s) on the notice of withdrawal
must be guaranteed by an eligible guarantor institution, unless the shares have
been tendered for the account of an eligible guarantor institution. If shares
have been tendered pursuant to the procedure for book-entry transfer as set
forth in "The Tender Offer--Procedures for Accepting Our Offer and Tendering
Shares," any notice of withdrawal must specify the name and number of the
account at DTC to be credited with the withdrawn shares.


    WE WILL DETERMINE, IN OUR SOLE DISCRETION, ALL QUESTIONS AS TO THE FORM AND
VALIDITY (INCLUDING TIME OF RECEIPT) OF ANY NOTICE OF WITHDRAWAL. OUR
DETERMINATION WILL BE FINAL AND BINDING. NEITHER WE, OUR PARENT, STC,
SCHLUMBERGER NOR ANY OF SCHLUMBERGER'S, STC'S, OUR PARENT'S OR OUR RESPECTIVE
AFFILIATES OR ASSIGNS, OUR DEALER MANAGER, OUR DEPOSITARY, OUR INFORMATION
AGENT, OR ANY OTHER PERSON WILL BE UNDER ANY DUTY TO GIVE ANY NOTIFICATION OF
ANY DEFECTS OR IRREGULARITIES IN ANY NOTICE OF WITHDRAWAL OR INCUR ANY LIABILITY
FOR FAILURE TO GIVE ANY NOTIFICATION.


    Withdrawals of shares may not be rescinded. If you have properly withdrawn
shares they will be deemed not to have been validly tendered for purposes of our
offer. However, withdrawn shares may be re-tendered at any time prior to the
Expiration Date by following one of the procedures described in "The Tender
Offer--Procedures for Accepting Our Offer and Tendering Shares."

5.  MATERIAL FEDERAL INCOME TAX CONSEQUENCES.

    The following is a summary of the principal U.S. federal income tax
consequences of our offer and the merger to holders whose shares are purchased
pursuant to our offer or whose shares are converted into the right to receive
cash in the merger (whether upon receipt of the merger consideration or pursuant
to the proper exercise of dissenter's rights). The discussion applies only to
holders of shares in whose hands shares are capital assets, and may not apply to
shares received pursuant to the exercise of employee stock options or otherwise
as compensation, or to holders of shares who are not citizens or residents of
the United States of America, who hold their shares as part of an integrated
investment (including a "straddle"), who are subject to alternative minimum tax
or who are subject to special rules, like financial institutions or insurance
companies. The discussion also assumes that the "collapsible corporation" rules
of the Internal Revenue Code do not apply to convert any gain to ordinary
income.

    This tax discussion is included for general information purposes only and is
based upon present law. Because individual circumstances may differ, you should
consult your own tax advisor to determine the applicability of the rules
discussed below to you and the particular tax effects of our offer and the
merger, including the application and effect of other federal, state, local and
other tax laws.

    The receipt of payment for shares accepted in our offer and the receipt of
cash pursuant to the merger (whether as merger consideration or pursuant to the
proper exercise of dissenter's rights) will be a taxable transaction for federal
income tax purposes (and also may be a taxable transaction under applicable
state, local and other income tax laws). In general, for federal income tax
purposes, a holder of shares will recognize gain or loss equal to the difference
between the holder's adjusted tax basis in the shares sold pursuant to our offer
or converted to cash in the merger and the amount of cash received therefor.
Gain or loss must be determined separately for each block of shares (i.e.,
shares acquired at the same cost in a single transaction) sold pursuant to our
offer or converted to cash in the merger. The gain or loss will be capital gain
or loss. Individual holders generally will be subject to federal income tax on
the net amount of the gain at a maximum rate of 20% if the holder's holding
period for the shares exceeds 12 months. The deduction of capital losses is
subject to limitations.

    Payments in connection with our offer or the merger may be subject to backup
withholding at a 31% rate. Backup withholding generally applies if you (1) fail
to properly furnish a social security

                                       37
<PAGE>
number or taxpayer identification number, or (2) furnish an incorrect social
security number or taxpayer identification number. Backup withholding is not an
additional tax but merely an advance payment of tax, which may be refunded to
the extent it results in an overpayment. Some persons, including corporations
and financial institutions generally, are exempt from backup withholding.
Penalties apply for failure to furnish correct information and for failure to
include the reportable payments in income. You should consult with your own tax
advisor as to your qualifications for exemption from withholding and the
procedure for obtaining such exemption.

6.  PRICE RANGE OF CONVERGENT'S COMMON STOCK.

    According to Convergent's Quarterly Report on Form 10-Q for the quarter
ended June 30, 2000 and information supplied by Convergent, the Convergent
shares were approved for listing on the Nasdaq National Market under the symbol
"CVGP" on August 1, 2000. In August 2000, Convergent completed its initial
public offering of 5,000,000 shares of its common stock at a price of $7.00 per
share, for aggregate proceeds of approximately $34.7 million. The lead manager
of that offering was Robertson Stephens Inc.

    According to the Convergent 10-Q, Convergent has never paid cash dividends
on its common stock and intends to retain earnings for the growth and expansion
of its business and not to declare or pay any cash dividends. Convergent agreed
in the merger agreement that, without the prior written consent of us or our
Parent, it will not declare, set aside or pay any dividend or other distribution
on any shares of capital stock of Convergent.

    The following table sets forth the high and low sales prices per Convergent
share on the Nasdaq National Market for the periods indicated, as reported in
published financial sources.

<TABLE>
<CAPTION>
CALENDAR YEAR                                               HIGH       LOW

  Fourth Quarter (through October 25, 2000).............  $   7.84   $   4.34
</TABLE>

    On October 13, 2000, the last full day of trading prior to the public
announcement of the execution of the merger agreement, the closing sale price
per Convergent share on the Nasdaq National Market was $4.72. On October 25,
2000, the last full trading day before the printing of this Offer to Purchase,
the closing sale price per share on the Nasdaq National Market was $7.84. YOU
ARE URGED TO OBTAIN A CURRENT MARKET QUOTATION FOR THE SHARES.

7. POSSIBLE EFFECTS OF OUR OFFER ON THE MARKET FOR THE SHARES; NASDAQ LISTING;
   MARGIN REGULATIONS AND EXCHANGE ACT REGISTRATION.

    POSSIBLE EFFECTS OF OUR OFFER ON THE MARKET FOR SHARES OF CONVERGENT.  Our
purchase of shares pursuant to our offer will reduce the number of shares that
might otherwise trade publicly and will reduce the number of holders of shares,
which could adversely affect the liquidity and market value of the remaining
shares held by the public.

    NASDAQ LISTING.  Depending upon the number of shares purchased pursuant to
our offer, the Convergent common stock may no longer meet the standards for
continued listing on the Nasdaq National Market. According to Nasdaq's published
guidelines, the shares would not be eligible to be included for listing if,
among other things, the number of shares that are not held directly or
indirectly by any officer or director of Convergent and by any other person who
is the beneficial owner of more than 10% of the total shares outstanding is less
than 750,000, or the number of holders of shares falls below 400. If, as a
result of the purchase of shares pursuant to our offer, the merger, the merger
agreement or otherwise, the Convergent common stock no longer meet the
requirements of the Nasdaq National Market for continued listing, the listing of
the shares will be discontinued. If that happens, the

                                       38
<PAGE>
market for the shares would be adversely affected. If the shares were no longer
eligible for listing on the Nasdaq National Market, quotations might still be
available from other sources. The extent of the public market for the shares and
the availability of quotations would, however, depend upon the number of
stockholders remaining at the time, the interest in maintaining a market in the
shares on the part of securities firms, the possible termination of registration
of the shares under the Exchange Act as described below and other factors.
Assuming we acquire the requisite number of shares to effect a delisting of the
shares, we intend to cause the delisting of the shares from Nasdaq following
consummation of our offer.

    EXCHANGE ACT REGISTRATION.  Convergent's common stock is currently
registered under the Exchange Act. If Convergent has less than 300 record
holders, Convergent may, upon application to the SEC, terminate that
registration under the Exchange Act. The termination of the registration of
Convergent's common stock under the Exchange Act would substantially reduce the
information required to be furnished by Convergent to holders of shares and to
the SEC and would make provisions of the Exchange Act, like the short-swing
profit recovery provisions of Section 16(b) of the Exchange Act, the requirement
of furnishing a proxy statement in connection with stockholders' meetings
pursuant to Section 14(a) or 14(c) of the Exchange Act and the related
requirements of an annual report, and the requirements of Rule 13e-3 under the
Exchange Act with respect to "going private" transactions, no longer applicable
to Convergent's common stock. In addition, once Convergent ceases to make its
public filings, affiliates of Convergent and persons holding "restricted
securities" of Convergent may have difficulty selling their shares pursuant to
Rule 144 promulgated under the Securities Act. We currently intend to seek to
cause Convergent to terminate the registration of the Convergent common stock
under the Exchange Act as soon after consummation of our offer as the
requirements for termination of registration are met.

    MARGIN REGULATIONS.  Shares of Convergent's common stock are currently
"margin securities," as defined under the rules of the Board of Governors of the
Federal Reserve System, which has the effect, among other things, of allowing
brokers to extend credit on shares of Convergent common stock used as
collateral. Depending upon factors similar to those described above regarding
listing and market quotations, following our offer it is possible that the
shares might no longer constitute "margin securities" for purposes of the margin
regulations of the Board of Governors of the Federal Reserve Board, with the
effect that shares could no longer be used as collateral for loans made by
brokers. In addition, if we terminate registration of the shares under the
Exchange Act, the shares would no longer constitute "margin securities."

    The major assumptions made by Convergent with respect to Convergent's
projections were as follows:

    - revenues increased by 24.6% from 1999 to 2000, 53.2% from 2000 to 2001,
      and 43.8% from 2001 to 2002;

    - overall gross margin was 36.2% in 1999, gross margins are expected to
      increase to 41.1% in 2000, 43.5% in 2001, and 44.6% in 2002;

    - operating margin was 10.9% in 1999 (excluding nonrecurring charges and
      stock compensation expense), operating margins are expected to drop to
      1.6% in 2000, before increasing to 9.1% in 2001, and 13.2% in 2002;

    - net profit margins were -22.9% in 1999, and are expected to be -2.7% in
      2000, 4.1% in 2001, and 7.1% in 2002; and

    - an effective tax rate of 39.0% was utilized.

    These projections are forward-looking statements. These forward-looking
statements are based on Convergent's current expectations and are subject to a
number of risks, uncertainties and assumptions. Among the important factors that
could cause actual results to differ significantly from those expressed or
implied by the forward-looking statements are Convergent's dependence on a
limited number of significant clients and the loss of any major client or the
loss or reduction in scope of any significant project, unexpected project
delays, project cancellations or the failure to obtain new projects and
increased costs from any associated employee underutilization; the failure to
maintain costs under Convergent's fixed-price contracts at or below the
estimated levels; Convergent's reliance on a single subcontractor for its data
conversion services and the failure of that subcontractor to perform services on
a timely basis; the failure of Convergent's eBusiness transformation products
and services to be accepted in the marketplace; the intense competition in
Convergent's industry; technological change; damage to Convergent's reputation
which could result from unexpected network interruptions, undetected errors or
defects in Convergent's services, breaches of Convergent's network security or
computer viruses or government audits; the risk that Convergent's utility and
government clients will

                                       43
<PAGE>
postpone or cancel projects if there is an economic downturn or if they are
unable to comply with their regulatory requirements; demand for Convergent's
services could decrease if the rate of deregulation in the utility industry
slows; the imposition of new burdensome government regulations and legal
uncertainties regarding the Internet which could increase Convergent's costs or
limit its operations; the risk that Convergent's intellectual property and
proprietary rights may not be fully protected; Convergent's inability to
negotiate contracts which permit it to reuse its software codes and
methodologies; the risk that Convergent will fail to manage and maintain its
growth, including its international growth; Convergent's need to successfully
develop awareness of its brand names; the risk that Convergent may be subject to
employment-related claims relating to the hiring of new employees; the potential
need for additional financing; as well as the other risk factors affecting
Convergent detailed from time to time in the documents filed by Convergent with
the Securities and Exchange Commission. Accordingly, there can be no assurance
that Convergent's projections will be realized, and actual results may prove to
be materially higher or lower than those contained in the projections. The
inclusion of this information should not be regarded as an indication that we,
Convergent or anyone else who received this information considered it a reliable
predictor of future events, and this information should not be relied on as
such. None of us, Convergent or any of our respective representatives assumes
any responsibility for the validity, reasonableness, or completeness of the
projected financial information, and Convergent has made no representation to us
regarding such information.

11. FINANCING OF OUR OFFER AND THE MERGER.

    We estimate the maximum total funds required to consummate our offer and the
merger is approximately $276 million. We estimate our related fees and expenses
to be approximately $4.0 million. See "Tender Offer--Fees and Expenses."

    Our offer is not conditioned upon any financing arrangements. We will obtain
all necessary funds required to consummate the transaction through capital
contributions or advances made by STC. STC plans to make these contributions or
advances from funds on hand and through borrowings under the revolving credit
line under its existing credit agreement, dated as of August 31, 1998, with
Banque Nationale De Paris, The Chase Manhattan Bank and Citibank, N.A., as
agents, and Banque Nationale De Paris, Chase Securities Inc. and Citicorp
Securities, Inc., as lead arrangers, and ABN Amro Bank N.V., as arranger.

    The credit agreement consists of a senior unsecured (1) $1.0 billion
revolving credit commitment and (2) $1.8 billion term commitment. The final
maturity date for the outstanding loans under the credit agreement is
August 31, 2003.

    At STC's option, any advance under the credit agreement made to it will be
available at either the "base rate" or the "eurodollar rate." The "base rate" is
a fluctuating rate equal to the greater of (1) Citibank's rate of interest
publicly announced as its base rate and (2) 1/2 of one percent per annum above
the federal funds rate. The "eurodollar rate" is a periodic fixed rate equal to
the London interbank market, commonly referred to as LIBOR, plus the applicable
margin, which is an amount that will vary based on a pricing grid with
applicable spreads based on the ratio of STC's adjusted cash flow to its
interest expense.

    In addition to the rates set forth above, STC may request competitive bids
from the participating lenders under the credit agreement for advances under its
revolving credit commitment. Each lender may bid at its discretion. STC may
accept one or more bids, provided that the aggregate outstanding advances of all
lenders on the date of, and giving effect to, any advance under a competitive
bid may not exceed $1.0 billion. STC does not intend to request a competitive
bid from the participating lenders for any loans made in connection with our
offer or the merger.

    Advances (other than competitive bid advances) may be prepaid without
penalty, in minimum amounts of $10.0 million and increments of $1.0 million.
Competitive bid advances cannot be prepaid. STC has not made any formal plans
concerning the repayment or refinancing of the credit agreement.

    The credit agreement contains representations and warranties, affirmative
covenants, financial covenants, negative covenants and events of default that
are usual and customary for facilities similar to the credit agreement. STC is
permitted to make borrowings under the credit agreement so long as its
representations and warranties contained in the credit agreement are correct in
all material respects and so long as no event of default has occurred and is
continuing.

    No alternative financing plans or arrangements have been made in the event
STC is unable to borrow the funds under its credit agreement described above in
connection with our offer and the merger.

    This summary is qualified in its entirety by reference to the credit
agreement, which we incorporate by reference, and which has been filed as an
exhibit to the Schedule TO in connection with our offer.

Condition, decrease the number of shares sought in our offer, change the form of
or decrease the amount of consideration to be paid, impose conditions to our
offer in addition to those set forth in "The Tender Offer--Conditions of Our
Offer" or amend any other term in our offer which is materially adverse to
Convergent's stockholders.

    THE MERGER.  The merger agreement provides that, upon the terms and subject
to the conditions in the merger agreement, and in accordance with Delaware law,
we will be merged with and into Convergent. As a result of the merger, our
separate corporate existence will cease and Convergent will continue as the
surviving corporation and will become a wholly owned subsidiary of our Parent.
Upon consummation of the merger, each issued and then outstanding share (other
than shares held in the treasury of Convergent and any shares that are held by
stockholders who have not voted in favor of the merger or consented thereto in
writing and who will have demanded and perfected their appraisal rights for such
shares in accordance with Delaware law) will be canceled and converted
automatically into the right to receive the merger consideration, which will be
equal to the consideration given pursuant to our offer.

    The merger agreement provides that our directors and Convergent's officers
immediately prior to the effective time of the merger will be the directors and
officers of Convergent, as the surviving corporation. Subject to the merger
agreement, the certificate of incorporation of Convergent, as in effect
immediately prior to the effective time of the merger, will be the certificate
of incorporation of Convergent after the merger. Immediately following the
merger, the certificate of incorporation of Convergent will be amended and
restated to be substantially identical to ours immediately prior to the
effective time of the merger. Subject to the merger agreement, our bylaws, as in
effect immediately prior to the effective time of the merger, will be the bylaws
of Convergent after the merger.

    STOCKHOLDERS' MEETING.  If required by applicable law in order to consummate
the merger, Convergent, acting through its board of directors, will, in
accordance with applicable law, duly call, give notice of, convene and hold a
special meeting of its stockholders, as promptly as practicable following the
acceptance for payment and purchase of shares by us pursuant to our offer, for
the purpose of considering and taking action upon the adoption of the merger
agreement. If we acquire at least a majority of the outstanding shares in our
offer, we will have sufficient voting power to adopt the merger agreement
without requiring other stockholders to vote in favor of adoption of the merger

                                       52
<PAGE>
agreement. We have agreed to cause all shares then owned beneficially by us to
be voted in favor of the adoption of the merger agreement. The merger agreement
provides that, if we acquire at least 90% of the then outstanding shares, we,
our Parent, STC and Convergent will take all necessary and appropriate action to
cause the merger to become effective, in accordance with Delaware law, as soon
as practicable after that acquisition, without a meeting of Convergent's
stockholders.

    PROXY STATEMENT.  If required by applicable law in order to consummate the
merger, Convergent, acting through its board of directors, will, in accordance
with applicable law:

    - prepare and file with the SEC a preliminary proxy or information statement
      relating to the merger and the merger agreement;

    - use its best efforts to obtain and furnish information required to be
      included by the SEC in the proxy statement;

    - after consultation with our Parent, respond promptly to any comments made
      by the SEC or its staff with respect to the preliminary proxy or
      information statement;

    - cause the proxy statement to be mailed to its stockholders;

    - use its commercially reasonable efforts to solicit proxies in favor of the
      adoption of the merger agreement; and

    - take all other action necessary or advisable to secure any vote or consent
      of stockholders required by Delaware law to effect the merger.

    Convergent has agreed to include in the proxy statement the recommendation
of the board of directors of Convergent that stockholders of Convergent vote in
favor of the adoption of the merger agreement.

    CONDUCT OF BUSINESS BY CONVERGENT PENDING THE MERGER.  In the merger
agreement, Convergent agreed that between October 13, 2000 and the date on which
our Parent appoints a majority of the members of the board of directors of
Convergent, except as expressly contemplated by the merger agreement or the
tender agreements or as agreed in writing by our Parent (which consent will not
be unreasonably withheld):

      be conducted only in the usual, regular and ordinary course and

      and each subsidiary of Convergent will use its commercially reasonable
      efforts to preserve its business organization substantially intact, keep
      available the services of its current officers and employees and maintain
      its existing relations with franchisees, customers, suppliers, creditors,
      business partners and others having significant business dealings with it,
      so that the goodwill and ongoing business is materially unimpaired at the
      effective time of the merger;

      any shares of any class or series of its capital stock or any voting debt,
      other than shares reserved for issuance on October 13, 2000 pursuant to

    - except as otherwise specifically provided in the merger agreement or in

      will make or offer to make any material change in the compensation payable
      or to become payable to any of its officers, directors, employees, agents
      or consultants (other than normal recurring increases in wages to
      employees who are not officers or directors or affiliates in the ordinary

      with past practice), (3) adopt or pay, grant, issue, accelerate or accrue

    - neither Convergent nor any subsidiary of Convergent will settle or

      for in Convergent's financial statements contained in filings by

      commit to take, any action that would be reasonably likely to result in
      any of the conditions to our offer or any of the conditions to the merger

      Convergent contained in the merger agreement inaccurate in any material
      respect at, or as of any time prior to the effective time of the merger,
      or that would materially impair the ability of Convergent, our Parent, us
      or the holders of shares to consummate our offer or the merger in
      accordance with its terms or materially delay consummation;

    - Convergent will not permit its plan administrator or similar person or

    BOARD REPRESENTATION.  The merger agreement provides that promptly after the
later to occur of (1) the purchase of and payment for any shares by our Parent
or any of its subsidiaries as a result of which our Parent and its subsidiaries
beneficially own at least a majority of then outstanding shares and
(2) compliance with Section 14(f) of the Exchange Act, and Rule 14f-1
thereunder, our Parent will be

                                       55
<PAGE>
entitled to designate up to such number of directors, rounded up to the next
whole number, on Convergent's board of directors as will give our Parent
representation on the board equal to the product of the total number of
directors on the board (giving effect to the directors elected pursuant to the
merger agreement) multiplied by the percentage of the total outstanding number
of shares that we or any affiliate of ours beneficially owns. Convergent will,
upon request of our Parent, use its best efforts promptly either to increase the
size of its board of directors or to secure the resignations of such number of
its incumbent directors, or both as is necessary to enable such designees of our
Parent to be so elected or appointed to Convergent's board of directors, and
Convergent will take all actions available to Convergent to cause such designees
of our Parent to be so elected or appointed at that time. At that time,
Convergent will, if requested by our Parent, also take all action necessary to
cause persons designated by our Parent to have the same percentage
representation on each committee of Convergent's board of directors, each board
of directors (or similar body) of each subsidiary of Convergent, and each
committee (or similar body) of each board of directors.

    The parties have agreed that, in the event that our Parent's designees are
elected or appointed to Convergent's board of directors, all members of the
special committee of the board will remain on Convergent's board of directors.
The affirmative vote of a majority of the special committee will be required
after the acceptance for payment of shares pursuant to our offer and prior to
the effective time of the merger, before Convergent (1) amends or terminates the
merger agreement, (2) exercises or waives any of its rights, benefits or
remedies under the merger agreement if such exercise or waiver adversely affects
holders of shares (other than ours or our Parent), (3) takes any other action
under or in connection with the merger agreement if such action adversely
affects holders of shares (other than ours or our Parent) or (4) take any other
action on behalf of Convergent in connection with the merger agreement required
to be taken by Convergent's board of directors.

    ACCESS TO INFORMATION.  Convergent has agreed to (and will cause each of its
subsidiaries to) give the officers, employees, accountants, counsel and other
representatives of our Parent, upon reasonable notice given by our Parent to
Convergent prior to the later of the termination date of the merger agreement or
the date our Parent appoints a majority of the board of directors, reasonable
access to all its properties, books, contracts, commitments and records, and,
during that period, Convergent will (and will cause each of its subsidiaries to)
furnish reasonably promptly to our Parent a copy of each report, schedule,
registration statement and other document filed or received by it during such
period pursuant to the requirements of federal securities laws and all other
information concerning its business, properties and personnel as our Parent
reasonably requests. We have agreed to keep that information confidential,
except in limited circumstances.

    NOTIFICATION OF COMPETING TRANSACTIONS.  Convergent will promptly, and in
any event within twenty-four hours, notify our Parent of the existence of any
proposal, discussion, negotiation or inquiry received by Convergent, and
Convergent will promptly, and in any event within twenty-four hours, communicate
to our Parent the material terms of any proposal, discussion, negotiation or
inquiry, which could reasonably be expected to lead to an Acquisition Proposal,
which it may receive (and will promptly, and in any event within twenty-four
hours, provide to our Parent copies of any written materials received by
Convergent, any subsidiary of Convergent or their respective representatives in
connection with a proposal, discussion, negotiation or inquiry) and the identity
of the party making the proposal or inquiry or engaging in such discussion or
negotiation, and will immediately communicate to our Parent the status of the
proposal, discussion or inquiry. Convergent will promptly, but in any event
within 24 hours, provide to our Parent any non-public information concerning
Convergent provided to any other party which was not previously provided to our
Parent.

    An "Acquisition Proposal" means any proposal or offer from any person (other
than our Parent, us or any of our or our Parent's affiliates) to acquire
(1) all or a substantial part of the business or properties of Convergent or any
significant subsidiary of Convergent or any capital stock of Convergent, whether
by merger, tender offer, exchange offer, sale of assets, consolidation, other

                                       56
<PAGE>
business combination, recapitalization, reorganization, liquidation, dissolution
or other transactions involving Convergent or any significant subsidiary of
Convergent or (2) 15% or more of the capital stock or other equity interests in
Convergent or 100% of the capital stock or other equity interests in any
significant subsidiary of Convergent.

    As a general rule, neither Convergent's board of directors nor any committee
thereof can:

    - withdraw or modify, or propose to withdraw or modify in a manner adverse
      to our Parent or us, the approval or recommendation by such board of
      directors or any such committee of our offer, the merger agreement or the
      merger;

    - approve or recommend or propose to approve or recommend any Acquisition
      Proposal; or

    - enter into any agreement with respect to any Acquisition Proposal.

    However, prior to the time of acceptance for payment of shares pursuant to
our offer, Convergent's board of directors may withdraw or modify its approval
or recommendation of our offer, the merger agreement or the merger, approve or
recommend a Superior Proposal, or enter into an agreement with respect to a
Superior Proposal, in each case at any time after the third business day
following our Parent's receipt of written notice from Convergent advising our
Parent that the board of directors of Convergent has received a Superior
Proposal which it intends to accept, specifying the material terms and
conditions of the Superior Proposal, identifying the person making the Superior
Proposal. Convergent will not be entitled to enter into any agreement with
respect to a Superior Proposal unless and until the merger agreement is
terminated and Convergent has paid the termination fee due to our Parent.

    The merger agreement clearly does not prohibit Convergent or Convergent's
board of directors from (1) soliciting a Superior Proposal, (2) taking and
disclosing to Convergent's stockholders a position with respect to a tender or
exchange offer by a third party pursuant to Rules 14d-9 and 14e-2 under the
Exchange Act, or (3) making disclosure to Convergent's stockholders if, as and
when the board of directors of Convergent determines in good faith, after
consultation with outside counsel, that disclosure is required in order to
comply with their fiduciary duties to Convergent's stockholders under applicable
law; PROVIDED, HOWEVER, that Convergent will not, except as permitted by the
merger agreement, withdraw or modify, or propose to withdraw or modify, its
position with respect to our offer or the merger or approve or recommend, or
propose publicly to approve or recommend, any Acquisition Proposal, or enter
into any agreement with respect to any Acquisition Proposal.

    A "Superior Proposal" means an unsolicited Acquisition Proposal (but
changing the 15% amount in clause (a)(ii) of the definition of Acquisition
Proposal to 50%) which is (a) (1) a bona fide written offer, (2) capable of
being, and likely to be, funded on the terms disclosed, and (3) likely to be
consummated in accordance with its terms, each as determined in good faith by
the board of directors and consistent with the advice of an independent
investment bank and (b) the board of directors determines in good faith (after
(1) receiving advice from the Convergent's independent investment banking firm
that the Acquisition Proposal is superior, from a financial point of view, to
our offer, the merger and merger agreement and (2) consultation with outside
legal counsel that failure to take that action would likely be contrary to its
fiduciary duties to Convergent's stockholders under applicable law.

    Convergent agreed not to enter into any agreement with respect to a Superior
Proposal without giving us the opportunity to match the Superior Proposal and
unless and until the merger agreement is terminated and Convergent has paid the
termination fee.

    TREATMENT OF STOCK OPTIONS.  The merger agreement provides that, at the
effective time of the merger, each stock option of Convergent which is then
outstanding and unexercised will be converted into options to purchase common
stock of our Parent. Each option assumed by our Parent under the merger
agreement will continue to have, and be subject to, the same terms and
conditions set forth in Convergent's stock option plan and the applicable stock
option agreement then in effect, except that

                                       57
<PAGE>
(1) the option will be exercisable for that number of shares of our Parent's
common stock equal to the number of shares of Convergent's common stock subject
to such option immediately prior to the effective time of the merger, and
(2) the exercise price per share will remain as the exercise price per share in
effect for that option immediately prior to the effective time of the merger.
Consistent with the terms of Convergent's stock option plan and the documents
governing the outstanding options under the plan, the merger will not terminate
any of the outstanding options under Convergent's stock option plan. Within 20
business days after the effective time of the merger, our Parent will issue to
each person who, immediately prior to the effective time of the merger, was a
holder of an outstanding option under the Convergent's stock option plan, a
document in form and substance satisfactory to Convergent evidencing the
assumption of options by our Parent. All outstanding rights of Convergent which
it held immediately prior to the effective time of the merger will, at the
effective time of the merger, be assigned to our Parent in the merger and will
be exercisable by our Parent upon the same terms and conditions in effect
immediately prior to the effective time of the merger.

    DIRECTORS' AND OFFICERS' INDEMNIFICATION.  In the merger agreement, our
Parent agreed that, to the fullest extent permitted under applicable law after
the effective time of merger, our Parent will, and will cause Convergent to, as
the surviving corporation (or any successor), indemnify, defend and hold
harmless each present and former officer and director, fiduciary or agent of
Convergent or the subsidiaries of Convergent against all losses arising out of
actions or omissions occurring at or prior to the effective time of the merger
to the full extent permitted under applicable Delaware law, the terms of
Convergent's certificate of incorporation or by-laws, as in effect on
October 13, 2000.

    Our Parent or Convergent, as the surviving corporation, will maintain
Convergent's existing officers' and directors' liability insurance for at least
six years following the effective date of the merger. Parent may substitute
policies with substantially equivalent coverage and amounts which contain terms
no less favorable to the former directors or officers. In no event will our
Parent or Convergent be required to pay aggregate annual directors and officers
insurance premiums in excess of 200% of the aggregate premiums paid by
Convergent in the twelve months prior to October 13, 2000, on an annualized
basis; but if our Parent or Convergent is unable to obtain the amount of
insurance required by the merger agreement for the aggregate premium, our Parent
or Convergent will obtain as much insurance as can be obtained for an annual
premium not in excess of 200% of the aggregate directors and officers insurance
premiums paid by Convergent in the twelve months prior to October 13, 2000, on
an annualized basis.

    REPRESENTATIONS AND WARRANTIES.  The merger agreement contains various
customary representations and warranties of the parties thereto including

the merger agreement, receipt of board approval, the vote of stockholders

       or recommends a Superior Proposal, or enters into an agreement with
       respect to a Superior Proposal, in each case at any time after the third
       business day following our Parent's receipt of written notice from
       Convergent advising our Parent that the board of directors of Convergent
       has received a Superior Proposal which it intends to accept, specifying

       making the Superior Proposal, so long as Convergent makes simultaneous
       payment to our Parent of the termination fee; or

     - if we have breached in any material respect any of our representations,
       warranties, covenants or other agreements contained in the merger
       agreement and (1) that breach is not curable or (2) 20 days have elapsed

       has not been cured within the 20 day period.

    - By our Parent (on behalf of itself, STC and us):

     - if, due to an occurrence, involving a material breach by Convergent of
       its obligations under the merger agreement, we failed to commence our
       offer within 15 business days following the date of the initial public
       announcement of our offer;

     - if, prior to the purchase of shares by us pursuant to our offer,

       merger agreement or the merger or recommends the approval or acceptance
       of an Acquisition Proposal or executes a letter of intent, agreement in

<PAGE>
     - if, prior to the purchase of shares by us pursuant to our offer,

       20 days after the giving of written notice of that breach.

    EFFECT OF TERMINATION.  In the event of the termination of the merger
agreement or abandonment of the merger pursuant to the terms of the merger
agreement, written notice will be given to the other party or parties specifying
the provision of the merger agreement pursuant to which such termination or
abandonment is made, the merger agreement will become void and have no further
effect, without any liability or obligation on the part of STC, our Parent, us
or Convergent; except that (1) a number of administrative provisions survive
termination; (2) nothing in the merger agreement will relieve Convergent or any
of its affiliates from liability or damages resulting from any willful and
material breach of the merger agreement; and (3) nothing in the merger agreement
will relieve STC, our Parent or us or any of our affiliates from liability or
damages resulting from any breach of STC's, our Parent's or our the merger
agreement.

    EXPENSES; TERMINATION FEES.  Generally, each party will pay its own costs
incurred in connection with the merger agreement with the transactions
contemplated by the merger, our offer and the tender agreements; except the

funds:

      March 31, 2001 (or a later termination date, if extended in accordance
      with the merger agreement) and, before that time, there was publicly
      announced another Acquisition Proposal by a person other than our Parent,
      us or any of our affiliates (and that Acquisition Proposal has not been
      withdrawn prior to the time of termination), and at any time prior to, or
      within twelve months after the termination of the merger agreement,
      Convergent has consummated a transaction with respect to that Acquisition
      Proposal;

SUBSCRIPTION AND CONTRIBUTION AGREEMENT

    ON OCTOBER 13, 2000, OUR PARENT ENTERED INTO THE SUBSCRIPTION AND
CONTRIBUTION AGREEMENT WITH STC, CINERGY AND THE MANAGEMENT INVESTORS. WE
QUALIFY THE FOLLOWING SUMMARY OF THE SUBSCRIPTION AND CONTRIBUTION AGREEMENT IN
ITS ENTIRETY BY REFERENCE TO THE SUBSCRIPTION AND CONTRIBUTION AGREEMENT. WE
INCORPORATE BY REFERENCE THE SUBSCRIPTION AND CONTRIBUTION AGREEMENT WHICH IS
FILED WITH THE SEC AS AN EXHIBIT TO THE SCHEDULE TO WHICH WE FILED WITH THE SEC.
THE SUBSCRIPTION AND CONTRIBUTION AGREEMENT MAY BE EXAMINED AND COPIES MAY BE
OBTAINED IN THE MANNER SET FORTH IN "THE TENDER OFFER--INFORMATION CONCERNING
CONVERGENT."

                                       60
<PAGE>
    Pursuant to the subscription and contribution agreement, STC has agreed to
purchase a number of our Parent's shares at $8.00 per share sufficient to enable
us to pay (1) for all Convergent shares accepted for payment in the tender
offer, (2) $8.00 per Convergent share converted into cash pursuant to the merger
and (3) for all Convergent shares which we may be required to purchase pursuant
to employment agreements with certain executive officers.

    Pursuant to the subscription and contribution agreement, Cinergy has agreed
to contribute 1,083,280 Convergent shares for 1,083,280 of our Parent's shares
and the management investors have agreed to contribute approximately 12,465,000
shares of their Convergent common stock or options exercisable for Convergent
common stock (tendering to us their remaining shares) and receive an equal
number of shares of or options for our Parent's common stock. Based on the
anticipated number of our Parent's shares that will be outstanding following the
consummation of the tender offer, the merger and the transactions contemplated
by the subscription and contribution agreement, the shares of our Parent's
common stock received by all of the management investors and Cinergy will
represent approximately 28% of our Parent's outstanding stock (before giving
effect to any stock options or other issuances of our Parent's securities or
rights to acquire our Parent's securities).

    Pursuant to the subscription and contribution agreement, the management
investors and Cinergy made representations and warranties to our Parent, STC and
us and also agreed to do the following:

    - deliver, within 15 business days of the date of the subscription and
      contribution agreement (by November 2, 2000), their certificates
      representing their Convergent common stock;

    - treat their acquisition of our Parent's common stock as a tax free
      exchange in accordance with Section 351 of the Internal Revenue Code;

    - not to transfer their Parent common stock received pursuant to the
      subscription and contribution agreement except in compliance with the
      Securities Act and the stockholders' agreement; and

    - waive their rights to a jury trial and submit to the personal jurisdiction
      of any Federal court in the State of Delaware or any Delaware state court.

    Concurrently with the closing of the purchases and contributions pursuant to
the subscription and contribution agreement, our Parent, the management
investors and Cinergy will enter into a stockholders agreement. The stockholders
agreement will contain various rights and restrictions, including redemption,
tag-along and drag-along rights, certain restrictions on transfer and
indemnification provisions, in connection with such parties' ownership of equity
securities of our Parent following the merger. In addition, the stockholders
agreement will contain provisions regarding the constitution of the our Parent's
board of directors, including provisions permitting STC to designate a specified
number of directors and permitting Cinergy to designate one director so long as
Cinergy holds 500,000 shares of our Parent's common stock. In the event that the
purchases and contributions contemplated by the subscription and contribution
agreement are consummated after termination of the merger agreement, Cinergy and
the management investors will have a put right. This means that our Parent or
STC will be obligated, upon notice from the stockholder exercising such right,
to repurchase the shares of our Parent's common stock owned by such stockholder.
The stockholders agreement will also give the parties certain rights to register
their shares of our Parent's common stock under the Securities Act. This brief
description of the form of stockholders' agreement, which will be executed upon
the closing of the purchases and contributions pursuant to the subscription and
contribution agreement, is qualified in its entirety by reference to the
stockholders' agreement, a copy of which is incorporated herein by reference and
copies or forms of which have been filed with the SEC as exhibits to the
Schedule TO to which our offer is an exhibit. The stockholders' agreement may be

EMPLOYMENT AGREEMENTS

AGREEMENTS") WITH GLENN E. MONTGOMERY, JR. (THE "CEO") AND LARRY J. ENGELKEN,
SCOTT M. SCHLEY, ANDREA S. MAIZES, BRYAN R. MILEGER AND DAVID J. RUBINSTEIN,
KNOWN AS THE SENIOR EXECUTIVES, WHICH AS OF THE EFFECTIVE TIME OF THE MERGER
WILL SUPERSEDE AND REPLACE IN ALL RESPECTS THE SENIOR EXECUTIVES' CURRENT
EMPLOYMENT AGREEMENTS. IN THE EVENT THE MERGER AGREEMENT IS TERMINATED, EACH OF
THE NEW AGREEMENTS WOULD BE VOID AND THE SENIOR EXECUTIVES' CURRENT EMPLOYMENT
AGREEMENTS WOULD REMAIN IN FULL FORCE AND EFFECT. THE FOLLOWING SUMMARY OF THE
NEW AGREEMENTS IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE NEW AGREEMENTS,
COPIES OF WHICH ARE INCORPORATED HEREIN BY REFERENCE AND COPIES OR FORMS OF
WHICH HAVE BEEN FILED WITH THE SEC AS EXHIBITS TO THE SCHEDULE TO TO WHICH OUR
OFFER IS AN EXHIBIT. THE NEW AGREEMENTS MAY BE EXAMINED AND COPIES MAY BE
OBTAINED IN THE MANNER SET FORTH IN "THE TENDER OFFER--INFORMATION CONCERNING
CONVERGENT."

    THE CEO.  Mr. Montgomery's New Agreement provides that, as of the effective
time of the merger, he will serve as Chief Executive Officer and President of
Convergent. The initial term of employment is for a period of three years.
Thereafter, the New Agreement will automatically renew for one year periods,
provided neither we nor Mr. Montgomery give written notice of an intent not to
renew the New Agreement.

    - Mr. Montgomery's present annual salary of $225,000 will continue up to the
      effective time of the merger; thereafter Mr. Montgomery's initial annual
      salary will be determined by the compensation committee of the board of
      directors of our Parent, which will include one disinterested director
      nominated by Mr. Montgomery. Subsequent annual adjustments to
      Mr. Montgomery's annual salary will be made by the compensation committee
      then in effect, with no requirement that Mr. Montgomery nominate a member
      of that committee.

                                       65
<PAGE>
    - Mr. Montgomery's bonus for calendar year 2000 is $50,000. The target
      annual bonus after calendar year 2000 will be set using the same procedure
      set for determining Mr. Montgomery's annual salary.

    - Mr. Montgomery's New Agreement provides for the sale of shares of
      Convergent to us, and also grants Mr. Montgomery an option to purchase
      certain shares in our Parent.

    - Mr. Montgomery will be entitled to participate in all employee benefit
      plans generally made available to other employees, as well as to
      "grossed-up" reimbursements for the costs of a $4,000,000 life insurance
      policy and to certain other fringe benefits.

    - Convergent may terminate Mr. Montgomery's employment at any time for
      "Cause" (as defined in the New Agreement) and upon thirty days' written
      notice without "Cause." Mr. Montgomery may terminate his employment with
      "Good Reason" (as defined in the New Agreement) upon written notice and
      failure by Convergent to cure within 20 days. Mr. Montgomery may terminate
      his employment agreement without "Good Reason" upon 30 days' notice. The
      New Agreement may be terminated at any time upon the mutual agreement of
      the parties. If Mr. Montgomery's employment were to terminate without
      "Cause," or if Mr. Montgomery were to terminate his employment for "Good
      Reason," or if the New Agreement were to terminate because of
      Mr. Montgomery's disability (as defined in the New Agreement), then
      Mr. Montgomery would be entitled to continuation of his employee benefits
      and salary for a period of six months and, in the case of termination
      without "Cause" or by Mr. Montgomery for "Good Reason" only, to exercise
      his option to require our Parent to purchase his remaining shares of our
      Parent. If Mr. Montgomery's employment were to terminate for "Cause" and
      such "Cause" was a failure to adequately perform material responsibilities
      and duties in a professionally reasonable manner or in accordance with
      Convergent's work standards, then Mr. Montgomery would be entitled to a
      continuation of his employee benefits and salary for a period of one
      month.

    - If Mr. Montgomery's employment were to terminate because of
      Mr. Montgomery's death, then his dependents would be entitled to a six
      month continuation of his employee benefits and to payment of one month of
      Mr. Montgomery's salary.

    - Mr. Montgomery's New Agreement contains a one year post-termination
      non-competition provision, as well a one year post-termination prohibition
      on the solicitation of our customers or employees.

    - The New Agreement also contains provisions concerning the protection of
      Convergent's trade secrets and other intellectual property.

    - In consideration for the termination of his prior employment agreement,
      Mr. Montgomery will receive a one-time payment of $500,000.

    - The New Agreement provides Mr. Montgomery with the discretion to allocate,
      among one or more of the senior management of Convergent, no less than 25%
      of any over-allotment options granted in connection with any underwritten
      public offering of shares of our Parent's common stock.

    THE SENIOR EXECUTIVES.  The New Agreements for Messrs. Engelken, Schley,
Mileger and Rubinstein and for Ms. Maizes are substantially similar and include
the following terms:

    - The initial term of employment is for a period of three years. Thereafter,
      the New Agreement will automatically renew for one year periods, provided
      neither Convergent nor the senior executive give written notice of an
      intent not to renew the New Agreement.

    - The senior executive's annual salary will be reviewed at least annually,
      and may be increased but not decreased. The senior executive will also
      receive annual cost of living adjustments.

                                       66
<PAGE>
    - Bonus arrangements for calendar year 2000 which were in place prior to
      execution of the New Agreement will remain in place. Beginning with
      calendar year 2001, the senior executive will be eligible for performance
      bonuses in an amount between 50% and 100% of the senior executive's annual
      salary.

    - Each senior executive's New Agreement (except Mr. Engelken's) provides for
      the sale of certain shares of Convergent to us, and each New Agreement
      grants the senior executive an option to purchase certain shares in our
      Parent.

    - The senior executive will be entitled to participate in all employee
      benefit plans generally made available to other employees. In addition,
      the senior executives will be entitled to participate in certain other
      fringe benefits.

    - Convergent may terminate the senior executive's employment at any time for
      "cause" and upon thirty days' written notice without "cause." The senior
      executive may terminate his or her employment with "good reason" upon
      written notice and failure by Convergent to cure within 20 days. The
      Senior Executive may terminate his or her employment agreement without
      "good reason" upon 30 days' notice. The New Agreement may be terminated at
      any time upon the mutual agreement of the parties.

    - If the senior executive's employment were to terminate without "cause," or
      if the senior executive were to terminate his or her employment for "good
      reason," then the senior executive would be entitled to continuation of
      his or her employee benefits and salary for a period of six months and to
      exercise his or her option to require our Parent to purchase his or her
      remaining shares of our Parent. If the senior executive's employment were
      to terminate for "cause" and such "cause" was a failure to adequately
      perform material responsibilities and duties in a
      professionally-reasonable manner or in accordance with Convergent's work
      standards, then the senior executive would be entitled to continuation of
      his or her employee benefits and salary for a period of one month. If the
      senior executive's employment were to terminate because of death or
      disability (as defined in the New Agreement), then either senior executive
      or his or her dependents would be entitled to a six month continuation of
      the senior executive's employee benefits and to payment of three months'
      salary upon termination for disability and one month's salary upon the
      death of the senior executive.

    - The senior executives' New Agreements contain a one year post-termination
      non-competition provision, as well a one year post-termination prohibition
      on the solicitation of Convergent's customers or employees. The New
      Agreements also contain provisions concerning the protection of
      Convergent's trade secrets and other intellectual property.

    The titles and salaries for each of the senior executives other than the CEO
are as follows:

    - Mr. Engelken: Executive Vice President of Strategic Accounts. $200,000
      annual salary.

    - Mr. Schley: Executive Vice President of Finance. $176,400 annual salary.

    - Ms. Maizes: Executive Vice President of Resource Management. $200,000
      annual salary.

    - Mr. Mileger: Chief Financial Officer, Treasurer and Assistant Secretary.
      $200,000 annual salary.

    - Mr. Rubinstein: Executive Vice President of Global Operations. $225,000
      annual salary.

14. LEGAL MATTERS AND REGULATORY APPROVALS.


    GENERAL.  Based upon its examination of publicly available information with
respect to Convergent and the review of information furnished by Convergent to
STC, Schlumberger and their affiliates and discussions between representatives
of affiliates of STC and Schlumberger with representatives of Convergent during
STC's and Schlumberger's investigation of Convergent, except to the extent set
forth below, neither we, STC nor Schlumberger are aware of any approval or other
action by any domestic (federal or state) or foreign governmental authority,
which in either case would be required prior to our acquisition of shares
pursuant to our offer. Should any approval or other action be required, it is
our present intention to seek the approval or action. We do not currently
intend, however, to delay the purchase of shares tendered pursuant to our offer
pending the outcome of any action or the receipt of any approval (subject to our
right to decline to purchase shares if any of the conditions in "The Tender
Offer--Conditions of Our Offer" will have occurred). There can be no assurance
that any approval or other action, if needed, would be obtained without
substantial conditions or that adverse consequences might not result to our
business or the business of Convergent, STC or Schlumberger or that parts of our
business or the businesses of Convergent, STC or Schlumberger might not have to
be disposed of or held separate or other substantial conditions complied with in
order to obtain such approval or other action or in the event that such approval
was not obtained or such other action was not taken. Our obligation under our
offer to accept for payment and pay for shares is subject to conditions,
including conditions relating to the legal matters discussed in this
Section 14. See "The Tender Offer--Conditions of Our Offer" for additional
conditions of our offer.



    Schlumberger, STC and Convergent conduct operations in a number of
jurisdictions where other regulatory filings or approvals may be required or
advisable in connection with the completion of the merger. Schlumberger, STC and
Convergent are currently in the process of reviewing whether filings or
approvals may be required or desirable in these jurisdictions which may be
material to Schlumberger, STC and Convergent and its subsidiaries. It is
possible that one or more of these filings may not be made, or one or more of
these approvals, which are not as a matter of practice required to be obtained
prior to effectiveness of a merger transaction, may not be obtained, prior to
the merger.


    ANTITRUST.  Under U.S. antitrust laws and the rules that have been
promulgated thereunder by the FTC, some acquisition transactions may not be
consummated unless information has been furnished to the Antitrust Division and
the FTC and waiting period requirements have been satisfied. Our acquisition of
shares pursuant to our offer is subject to these requirements. See "The Tender
Offer--Acceptance for Payment and Payment for Shares."


    Schlumberger filed the appropriate Premerger Notification and Report Forms
in connection with the purchase of shares pursuant to our offer with the
Antitrust Division and the FTC on October 31, 2000.


                                       69
<PAGE>

    Under the applicable provisions of U.S. antitrust laws, the purchase of
shares pursuant to our offer may not be consummated until the expiration of a
15 day waiting period following the filing by Schlumberger. Accordingly, the
waiting period under U.S. antitrust laws applicable to the purchase of shares
pursuant to our offer will expire at 11:59 p.m., New York City time, on November
15, 2000, unless the waiting period is earlier terminated by the FTC and the
Antitrust Division or extended by a request from the FTC or the Antitrust
Division for additional information or documentary material prior to the
expiration of the waiting period. Schlumberger has requested early termination
of the waiting period applicable to the transaction. There can be no assurance,
however, that the 15-day antitrust waiting period will be terminated early. If
either the FTC or the Antitrust Division were to request additional information
or documentary material from Schlumberger, Convergent or both companies with
respect to our acquisition of shares, the waiting period would expire at 11:59
p.m., New York City time, on the 10th day after the date of substantial
compliance with the request(s). Thereafter, the waiting period could be extended
only with the consent of Schlumberger. If the acquisition of shares is delayed
pursuant to a request by the FTC or the Antitrust Division for additional
information or documentary material pursuant to U.S. antitrust laws, our offer
will be extended and, in any event, the purchase of and payment for shares will
be deferred until 10 days after the request is substantially complied with,
unless the waiting period is sooner terminated by the FTC and the Antitrust
Division. Only one extension of the waiting period pursuant to a request for
additional information is authorized by U.S. antitrust laws and the rules
promulgated thereunder, except by court order. Any extension of the waiting
period will not give rise to any withdrawal rights not otherwise provided for by
applicable law. See "The Tender Offer--Withdrawal Rights." It is a condition to
our offer that the waiting period applicable under U.S. antitrust laws to our
offer expire or be terminated. See "The Tender Offer--Acceptance for Payment and
Payment for Shares" and "The Tender Offer--Conditions of Our Offer."


    The FTC and the Antitrust Division frequently scrutinize the legality under
the antitrust laws of transactions such as our proposed acquisition of shares
pursuant to our offer. At any time before or after our purchase of shares
pursuant to our offer, the FTC or the Antitrust Division could take any action
under the antitrust laws as it deems necessary or desirable in the public
interest, including seeking to enjoin the purchase of shares pursuant to our
offer or seeking the divestiture of shares purchased by us or the divestiture of
substantial assets of Schlumberger, Convergent or their respective subsidiaries.
The merger agreement provides that in connection with the receipt of any
necessary approvals under the U.S. antitrust laws, neither Convergent nor any of
Convergent's subsidiaries can divest or hold separate or otherwise take or
commit to take any action that limits STC's or our freedom of action with
respect of, or their ability to retain, Convergent or any of Convergent's
subsidiaries or any material portions thereof or any of the businesses, product
lines, properties or assets of Convergent or any of its subsidiaries, without
STC's prior written consent (which may be withheld in STC's sole and absolute
discretion).


    Private parties and state attorneys general may also bring legal action
under federal or state antitrust laws under certain circumstances. Based upon an
examination of information available to Schlumberger and STC relating to the
businesses in which Schlumberger, STC, Convergent and their respective
subsidiaries are engaged, we, Schlumberger and STC believe that our offer will
not violate the antitrust laws. Nevertheless, there can be no assurance that a
challenge to our offer on antitrust grounds will not be made or, if a challenge
is made, what the result would be. See "The Tender Offer--Conditions of Our
Offer" for the conditions to our offer, including conditions with respect to
litigation.


    SHORT-FORM MERGER.  Section 253 of the Delaware General Corporation Law
provides, among other things, that, if the parent corporation owns at least 90%
of the outstanding shares of each voting class of a subsidiary corporation, the
merger of the subsidiary corporation and the parent corporation may be effected
by a resolution adopted and approved by the board of directors of the parent
corporation

                                       70
<PAGE>
and the appropriate filings with the Delaware Secretary of State, without any
action or vote on the part of the stockholders of the subsidiary corporation.
Under the Delaware General Corporation Law, if we acquire at least 90% of
Convergent's outstanding shares, we will be able to effect the merger without a
vote of the other stockholders of Convergent. In such event, STC, our Parent, we
and Convergent have agreed in the merger agreement to take all necessary and
appropriate action to cause the merger to become effective as soon as
practicable after such acquisition, without a meeting of Convergent's
stockholders. In the event that less than 90% of the shares then outstanding are
tendered pursuant to the offer, we may extend the offer for up to 20 business
days so that the merger may be consummated as described in this paragraph.

    LITIGATION.  On October 16, 2000, three class actions were filed in the
Court of Chancery of the State of Delaware against Convergent and each member of
its board of directors. Each of the actions alleges that the members of
Convergent's board of directors breached their fiduciary duties to Convergent
and to its stockholders by allegedly failing to maximize stockholder value in
connection with the merger agreement, our offer, the merger and the transactions
contemplated by the merger agreement. Two of the actions seek to enjoin
Convergent from proceeding with the offer and the merger, and all three of the
actions seek an award of unspecified damages. Convergent believes that each of
the three actions is without merit, and Convergent intends to vigorously defend
itself against each action. The three actions are as follows: (1) C.A.
No. 18426: STEVE SCHNIPPER V. GLENN E. MONTGOMERY, JR., SCOTT M. SCHLEY, ROBERT
SHARPE, JERRY MURDOCK, JOHN W. BLEND III, AND CONVERGENT GROUP CORPORATION; (2)
C.A. No. 18427: ARMEN MINASSIAN V. GLENN E. MONTGOMERY, JR., SCOTT M. SCHLEY,
ROBERT SHARPE, JERRY MURDOCK, JOHN W. BLEND III, AND CONVERGENT GROUP
CORPORATION and (3) C.A. No. 18431 NC: PATRICIA EICH V. GLENN E.
MONTGOMERY, JR., SCOTT M. SCHLEY, ROBERT SHARPE, JERRY MURDOCK, JOHN W. BLEND
III, AND CONVERGENT GROUP CORPORATION.

15. STATE TAKE-OVER LAWS.

    Convergent is incorporated under the laws of the State of Delaware. In
general, Section 203 of the General Corporation Law of the State of Delaware
prevents an "interested stockholder" (generally a person who owns or has the
right to acquire 15% or more of a corporation's outstanding voting stock, or is
an affiliate or associate of the corporation and was the owner of 15% or more of
the outstanding voting stock of the corporation within the prior 3 years) from
engaging in a "business combination" (defined to include mergers and similar
transactions) with a Delaware corporation for a period of three years following
the time the person became an interested stockholder unless, among other things,
prior to the time of the business combination the board of directors of the
corporation approved either (a) the business combination or (b) the transaction
which resulted in the stockholder becoming an interested stockholder.

    On October 13, 2000, prior to the execution of the merger agreement, based
upon the unanimous recommendation of the special committee of Convergent's board
of directors approved the merger and each of the transactions contemplated by
the merger agreement, approved by the board as a unitary transaction and not
separately.

    A number of other states have adopted laws and regulations applicable to
attempts to acquire securities of corporations which are incorporated, or have
substantial assets, stockholders, principal executive offices or principal
places of business, or whose business operations otherwise have substantial
economic effects, in such states. Convergent, directly or through its
subsidiaries, conducts business in a number of states throughout the United
States, some of which have enacted takeover laws. We do not know whether any of
these laws will, by their terms, apply to our offer or the merger and has not
complied with any such laws. Should any person seek to apply any state takeover
law, we will take any action as then appears desirable, which may include
challenging the validity or applicability of any such statute in appropriate
court proceedings. In the event it is asserted that one or more state takeover
laws is applicable to our offer or the merger, and an appropriate court does not

                                       71
<PAGE>
determine that it is inapplicable or invalid as applied to our offer, we might
be required to file information with, or receive approvals from, the relevant
state authorities. In addition, if enjoined, we might be unable to accept for
payment any shares tendered pursuant to our offer, or be delayed in continuing
or consummating our offer, and the merger. In such case, we may not be obligated
to accept for payment any shares tendered. See "The Tender Offer--Conditions of
Our Offer."

16. RIGHTS OF DISSENTING STOCKHOLDERS.


    We, our Parent, STC and Schlumberger do not believe that appraisal rights
are available in connection with our offer; however, appraisal rights may be
available in connection with the merger. If the merger is consummated,
stockholders who have not tendered their shares may have the right under
Delaware law to dissent from the merger and demand appraisal of, and to receive
payment in cash of the fair value of, their shares. Stockholders who perfect
appraisal rights by complying with the procedures set forth in Section 262 of
the Delaware General Corporation Law will be entitled to an appraisal by the
Delaware Court of Chancery of the fair value of the shares exclusive of any
element of value arising from the accomplishment or expectation of the merger.
In addition, dissenting stockholders may be entitled to receive payment of a
fair rate of interest from the date of consummation of the merger on the amount
determined to be the fair value of their shares.



    STC does not intend to object, assuming the proper procedures are followed,
to the exercise of appraisal rights by any stockholder and the demand for
appraisal of, and payment in cash for the fair value of, the shares. STC
intends, however, to cause Convergent, as the surviving corporation, to argue in
an appraisal proceeding that, for purposes of the proceeding, the fair value of
each share is less than or equal to the merger consideration.


    You should be aware that opinions of investment banking firms (including
Morgan Stanley's) as to the fairness from a financial point of view are not
necessarily opinions as to "fair value" under Delaware law.

    This summary of the rights of dissenting stockholders under Delaware law is
not a complete statement of the procedures to be followed by stockholders
desiring to exercise any dissenters' rights under Delaware law. The preservation
and exercise of dissenters' rights require strict adherence to the applicable
provisions of Delaware law. See Section 262 of the Delaware General Corporation
Law which is incorporated herein by reference and a copy of which has been filed
with the SEC as an exhibit to the Schedule TO to which our offer is an exhibit.

17. FEES AND EXPENSES.

    Except as set forth below, we will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of shares pursuant to our
offer.


    Salomon Smith Barney Inc. is acting as Dealer Manager for our offer and as
financial advisor to Schlumberger in connection with our offer and the merger,
for which services Salomon Smith Barney Inc. will receive customary

    STC has retained D.F. King & Co., Inc., as our Information Agent, and
Citibank, N.A., as our Depositary, in connection with our offer. The Information
Agent may contact holders of shares by mail, telephone, telex, telecopy,

18. MISCELLANEOUS.

    We are making our offer to Convergent stockholders solely through this
document and the related Letter of Transmittal. We are not aware of any
jurisdiction where the making of our offer is prohibited by any administrative
or judicial action pursuant to any valid state statute. If we become aware of
any valid state statute prohibiting the making of our offer or the acceptance of
shares pursuant thereto, we

                                       73
<PAGE>
will make a good faith effort to comply with that state statute. If, after a
good faith effort, we cannot comply with that state statute, our offer will not
be made to (nor will tenders be accepted from or on behalf of) the holders of
shares in that state. In any jurisdiction where the securities, blue sky or
other laws require our offer to be made by a licensed broker or dealer, our
offer will be deemed to be made on our behalf by one or more registered brokers
or dealers licensed under the laws of such jurisdiction.

    NO PERSON HAS BEEN AUTHORIZED TO GIVE ANY INFORMATION OR MAKE ANY
REPRESENTATION ON BEHALF OF US, OUR PARENT OR STC NOT CONTAINED IN THIS DOCUMENT
OR IN THE LETTER OF TRANSMITTAL, AND IF GIVEN OR MADE, THAT INFORMATION OR
REPRESENTATION MUST NOT BE RELIED UPON AS HAVING BEEN AUTHORIZED.


    Pursuant to Rule 14d-3 under the Exchange Act, we, STC and Schlumberger have
filed with the SEC the Schedule TO, together with exhibits, furnishing
additional information with respect to our offer. The Schedule TO and any
amendments to the Schedule TO, including exhibits, may be inspected at, and
copies may be obtained from, the same places and in the same manner as set forth
in "The Tender Offer--Information Concerning Convergent" (except that they will
not be available at the regional offices of the SEC).
