meeting will not revoke your proxy. If you have instructed a broker to vote your
shares, you must follow the instructions received from your broker to change
your vote.

      o     each of the voting agreement and the earnout agreement (as described
            in the section entitled "Related Agreements") must have been entered
            into and remain in full force and effect.

Conduct of Business Pending the Merger (See page 36)

      We have agreed to operate our business in the usual and ordinary course
and generally to preserve our business organization, properties and assets,
retain the services of our principal officers and key employees and maintain our
relationships with our principal customers and suppliers until the merger is
completed. In addition, we have agreed to a number of specific conditions on the
conduct of our business until the closing of the merger.

Termination of the Merger Agreement; Termination Fee (See page 44)

      The merger agreement may be terminated by the mutual written consent of
the company and PA Consulting Group, Inc.

      In addition, subject to qualifications, the merger agreement may be
terminated by either the company or PA Consulting Group, Inc. if:

      o     the other materially breaches any of its representations,
            warranties, covenants or agreements contained in the merger
            agreement and causes the conditions to closing relating to those
            representations, warranties, covenants and agreements to be
            unsatisfied, and such breach has not been cured, or by its nature or
            timing cannot be cured, within 30 days after written notice thereof;

      o     a final injunction or order prohibiting the merger is issued and is
            not appealable;

      o     our stockholders do not approve the merger agreement at the special
            meeting; or

      o     the merger is not consummated by the date which is 180 days after
            the date of the merger agreement, provided that the right to
            terminate the merger agreement is not available to any party whose
            breach of its obligations under the merger agreement has caused such
            termination and that applicable cure periods have run;

      PA Consulting Group, Inc. may terminate the merger agreement if:

      o     our board of directors accepts or recommends to its stockholders a
            "superior proposal," as described in the section entitled "No
            Solicitation of Proposals";

      o     any of our stockholders who are parties to the voting agreement
            breach in any material respect any representation, warranty, or
            agreement in the voting agreement without curing it and such breach
            denies PA Consulting Group, Inc. the material benefits contemplated
            by the voting agreement; or

      o     subject to certain notice and cure periods, after the date of the
            merger agreement, there shall occur and be continuing a material
            adverse effect relating to us.

      We may terminate the merger agreement if:

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

      o     our board of directors accepts or recommends to our stockholders a
            superior proposal, provided that our board of directors has
            materially complied with their obligations relating to negotiation
            with others under the merger agreement.

      Under the merger agreement, we are obligated to pay PA Consulting Group,
Inc. a termination fee of $5,000,000 if either we or PA Consulting Group, Inc.
terminates the merger agreement as a result of our board of directors accepting
or recommending to our stockholders a superior proposal.

No Solicitation of Proposals (See page 40)

      Until the merger is completed or the merger agreement is terminated, we
have generally agreed not to solicit, initiate, facilitate or encourage any
inquiries or engage in discussions that could be expected to result in an
"acquisition proposal," as described in the section entitled "No Solicitation of
Proposals".

      However, if we receive an unsolicited acquisition proposal that our board
of directors reasonably concludes, after consultation with an independent
investment bank, may constitute a superior proposal, we may furnish non-public
information regarding the acquisition proposal and may enter into discussions
with the person or entity who has made the acquisition proposal if we follow
other specified procedures.

Opinion of Financial Advisor (See page 20)

      Banc of America Securities LLC delivered an opinion to our board of
directors that as of June 19, 2000 the merger consideration was fair from a
financial point of view to the holders of our common stock. We have attached
this opinion as Appendix B to this proxy statement.

Interests of Certain Persons in the Merger (See page 24)

      In considering the recommendation of the board of directors with respect
to the merger, you should be aware that certain of our directors and executive
officers have interests in the merger that are different from, or are in
addition to, yours. These interests include:

      o     specified indemnification rights to which our directors and officers
            are entitled;

      o     payment of certain cash amounts for outstanding options to purchase
            our common stock; and

      o     employment and other agreements with certain of our executive
            officers and former directors and executive officers.

      As a result, these directors and officers may be more likely to vote in
favor of approving the merger and the merger agreement than if they did not have
these interests.

Regulatory Approvals (See page 28)

      The merger is subject to antitrust laws. On July 7, 2000, the company and
PA Consulting Group, Inc. each filed the required information and materials with
the Department of Justice and Federal Trade Commission. The applicable waiting
period has terminated. However, the Antitrust Division of the Department of
Justice, the Federal Trade Commission, state antitrust authorities or a private
person or entity may challenge the merger at any time before or after its
completion.

Certain Federal Income Tax Consequences of the Merger (See page 28)

       The merger will be a taxable transaction to our stockholders.
Stockholders will recognize long or short-term capital gain or loss in the
merger in an amount determined by the difference between the cash received and
their tax basis in the exchanged shares.

Accounting Treatment of the Merger (See page 29)

      The merger is expected to be accounted for using the purchase method of
accounting.

Appraisal Rights of Dissenting Stockholders (See page 29)

      If you are a stockholder who does not vote in favor of the merger
agreement, and you satisfy all other conditions of Section 262 of the Delaware
General Corporation Law you will be entitled to dissent and demand an appraisal
of the "fair value" of your shares. To exercise your appraisal rights, you must
deliver a written objection to the merger to us at or before the special
meeting. Your failure to follow the exact procedures specified under Section 262
of the Delaware General Corporation Law, which is included as Appendix C to this
proxy statement, will result in the loss of your dissenters' rights.

</TABLE>

(1)   The operating data for the year--ended December 31, 1995 reflect the
      combined results of operations of the RCG/Hagler Bailly, Inc. from January
      1, 1995 to May 24, 1995, the company from May 25, 1995 to December 31,
      1995, and the annual results of Apogee, TB&A, IGA and PHB.

(2)   The statements of operations data for the years ended December 31, 1995,
      1996 and 1997 include performance incentive compensation paid to PHB
      senior staff members in excess of a standard bonus set for their
      respective staff levels. The excess performance incentive compensation was
      included in cost of services and selling, general and administrative
      expenses was $6,260, $9,588 and $7,294 for the years ended December 31,
      1995, 1996 and 1997, respectively. In addition, the year ended December
      31, 1996 includes approximately $500 of cost of services, representing
      that portion of officer compensation that exceeded the compensation that
      would have been paid had the compensation plan adopted in January 1997
      been in effect for all of 1996; and the year ended December 31, 1999
      includes $10,868 in bonuses paid to key staff. In 1997 the Board adopted a
      resolution limiting the amount that may be set aside for bonuses to forty
      percent (40%) of net income before bonuses and taxes. In approving bonuses
      for 1999 the Board of Directors made an exception to this limitation.

(3)   In connection with an amendment to the Hagler Bailly, Inc. Employee
      Incentive and Non-Qualified Stock Option and Restricted Stock Plan and a
      reclassification of its common stock, each effective December 31, 1996,
      the company incurred non-recurring, non-cash charges to operations
      amounting to approximately $4,600 for options and approximately $1,600 for
      stock in 1996. In connection with a stock bonus to an employee, the
      company incurred a non-cash compensation charge to operations in the first
      quarter of 1997 of $65. PHB common stock issued or subject to issuance
      under subscriptions receivable entered into within 12 months preceding the
      closing of the merger were presumed to have been issued in contemplation
      of the proposed transaction and were accounted for at their fair market
      value at date of issuance. Accordingly, PHB recognized a non-recurring,
      non-cash, non-tax deductible compensation charges for the years ended
      December 31, 1997 and 1998 of approximately $9,900 and $2,600,
      respectively, representing the difference between the fair market and book
      value of shares of common stock then issuable.

(4)   On December 31, 1996, PHB liquidated its wholly owned subsidiary in the
      U.K. Of PHB's loss of $662 in 1996, $549 represented cumulative foreign
      currency translation losses that had previously been recorded as a
      separate component of the PHB's shareholders' equity. In 1997, $328 was
      recorded as management's estimate of the uncollectable net proceeds
      resulting from the liquidation.

(5)   For the year ended December 31, 1997, 1998 and 1999, the company recorded
      merger related and other nonrecurring costs of $1,235, $8,275 and $292,
      respectively, as a result of business combinations and related costs (see
      note 17 to the 1999 financial statements).

(6)   For the years ended December 31, 1995, 1996 and 1997, the company recorded
      extraordinary gains of $1,055, $145 and $2,336, respectively, as a result
      of extinguishment of debt at beneficial terms by TB&A.

(7)   Other income (expenses), net includes interest income, interest expense,
      minority interest, other income, and other expenses.

(8)   For the years ended December 31, 1998 and 1999, the company recorded asset
      impairment expenses of $1,107 and $4,591, respectively. In 1998, the
      expense was recorded as a result of certain software development costs
      which were impaired due to the duplication of technologies resulting from
      the company's business combinations and its joint venture with Cap Gemini.
      In 1999, the expense was recorded as a result of the impairment of
      goodwill associated with certain subsidiaries (see note 18 to the 1999
      financial statements).

                               THE SPECIAL MEETING

Date, Time, Place and Purpose of the Special Meeting

      This proxy statement is being furnished to stockholders as part of the
solicitation of proxies by our board of directors for use at the special meeting
and at any adjournments or postponements thereof.

      The special meeting is scheduled to be held on ___________, 2000 at ____
[a.m.] [p.m.] at our corporate headquarters, located at 1530 Wilson Boulevard,
Suite 400, Arlington, Virginia 22209.

      At the special meeting, stockholders will be asked to approve and adopt
the merger agreement and to transact any other business that is properly brought
before the special meeting or any postponement or adjournment thereof.

Record Date and Outstanding Shares

      Only holders of record of our common stock at the close of business on
_________, 2000, the record date, are entitled to notice of and to vote at the
special meeting or any adjournments thereof. As of the close of business on the
record date, there were 17,927,812 shares of common stock outstanding and
entitled to vote. These shares were held of record by approximately ___________
stockholders.

Vote and Quorum Required

      Holders of common stock are entitled to one vote for each share held on
the record date on all matters properly presented at the special meeting. The
presence, in person or by proxy, of the holders of a majority of the outstanding
shares of common stock entitled to vote is necessary to constitute a quorum for
the transaction of business at the special meeting. Approval of the merger
agreement requires the affirmative vote of the holders of a majority of the
outstanding shares of common stock entitled to vote.

Broker Non-Votes; Abstentions

      Broker "non-votes" and abstentions will be included in determining the
number of shares represented at the special meeting. Because approval of the
merger agreement requires the affirmative vote of the holders of a majority of
the outstanding shares of common stock entitled to vote, abstentions and broker
"non-votes" will have the same effect as a vote against approval of the merger
agreement. A broker "non-vote" occurs when a nominee holding shares for a
beneficial owner does not vote on a particular proposal because the nominee does
not have discretionary voting power on that item and has not received
instructions from the beneficial owner.

Stock Ownership of Management and Other Affiliates; Voting Agreement

      Certain directors, executive officers and affiliates who own an aggregate
of 2,170,849 shares of our common stock as of the record date, or approximately
12.1% of the outstanding shares, have executed a voting agreement with PA
Consulting Group, Inc. under which they have agreed to vote all of their shares
in favor of approval of the merger agreement. See "Related Agreements -- The
Voting Agreement" for a description of the terms of the voting agreement.


                                       10
<PAGE>

Voting and Revocation of Proxies

      All shares entitled to vote and represented by properly executed proxies
received prior to the special meeting, and not revoked, will be voted as
instructed on those proxies. Executed proxies with no instructions indicated
thereon will be voted "FOR" approval and adoption of the merger agreement.

      Our board of directors is not aware of any matters other than the approval
of the merger agreement that may be properly brought before the special meeting.
If any other matters are properly presented at the special meeting or any
adjournments or postponements of the special meeting for consideration, the
persons named in the accompanying proxy will vote the shares represented by all
properly executed proxies on such matters in such manner as determined in their
discretion.

      The accompanying form of proxy is for use at the meeting if a holder of
common stock is unable to attend in person. You may revoke your proxy at any
time before it is exercised at the meeting by taking any of the following
actions:

      o     delivering to our Corporate Secretary a written notice bearing a
            date later than the date of the proxy, stating that the proxy is
            revoked;

      o     signing and delivering a proxy relating to the same shares and
            bearing a later date prior to the vote at the special meeting; or

      o     attending the special meeting and voting in person, although
            attendance at the meeting will not, by itself, revoke a proxy.

      Any written notice of revocation or subsequent proxy should be sent before
the taking of the vote at the special meeting to Hagler Bailly, Inc., 1530
Wilson Boulevard, Suite 400, Arlington, Virginia 22209, Attention: Stephen V.R.
Whitman, Secretary.

       You should not send in any stock certificates with your proxies. A
transmittal form with instructions for the surrender of your stock certificates
will be mailed to you as soon as practicable after completion of the merger.

Solicitation of Proxies

       We will pay the expenses of soliciting proxies and the cost of printing
and mailing this proxy statement. In addition to soliciting proxies by mail,
proxies may be solicited personally or by telephone, facsimile, or other means
of communications, without additional remuneration, by directors, officers and
employees. We have retained a proxy solicitation firm, Corporate Investor
Communications, Inc., to assist us in the solicitation process for a fee of
approximately $5,000, plus out-of-pocket expenses. We will also request brokers,
custodians, nominees and other fiduciaries to send solicitation materials to
beneficial owners of shares of common stock and will reimburse them for their
reasonable expenses in connection therewith.

                                   THE MERGER

      The following is a summary of the material provisions of the merger. This
summary does not purport to describe all the terms of the merger and is
qualified in its entirety by reference to the merger agreement which is attached
as Appendix A to this proxy statement and is incorporated by reference. You are
urged to read the merger agreement carefully and in its entirety.

Background of the Merger

      On March 3, 1999 our management decided to retain Banc of America
Securities LLC ("Banc of America Securities") under a broad mandate to assist us
in exploring various strategic and financial alternatives in an effort to
maximize stockholder value, including possible acquisitions and sale
transactions. In subsequent months, however, we were disappointed with our
profit performance, the depressed level of our share price and our inability to
leverage our market position, intellectual capital and reputation to the benefit
of our shareholders.

      On September 27, 1999 we publicly announced that our board of directors
had engaged Banc of America Securities as our financial advisor to assist us in
exploring strategic and financial alternatives to maximize shareholder value,
including the potential sale or merger of the company.

      After discussions with management, Banc of America Securities undertook to
solicit interest in a potential sale or merger of the company. During October
and November 1999, in conjunction with management, Banc of America Securities
prepared a confidential memorandum concerning the company and its business.
Throughout December 1999 and January 2000, Banc of America Securities contacted
64 potential purchasers, including 45 potential strategic partners and 19
potential financial partners. Confidentiality agreements and a confidential
memorandum dated December 1999, were then sent to 32 potential purchasers,
including 18 potential strategic partners and 14 potential financial partners.
Banc of America Securities also distributed an addendum to the confidential
memorandum, dated January 2000, to potential purchasers. Initial indications of
interest were received between January 24, 2000 and February 4, 2000, from two
potential strategic partners for the entire company, two potential strategic
partners for the commercial consulting business on a stand-alone basis and three
potential strategic partners for the government consulting business on a
stand-alone basis.

        At a board of directors meeting on February 2, 2000, Banc of America
Securities reviewed for the board of directors the initial indications of
interest, and the board of directors requested that Banc of America Securities
invite five of the interested parties to attend management presentations and
complete their initial due diligence and submit proposals for a transaction with
the company. Banc of America Securities received a third indication of interest
for the commercial consulting business two weeks after the initial bid date
which it also discussed with the board of directors. We hosted five management
presentations between February 14, 2000 and March 1, 2000, and the five
interested parties interviewed members of our management and reviewed additional
information made available by the company regarding its business operation,
contracts, employee benefit plans, business projections and other operational
information. Final indications of interest were received on March 17, 2000 and
March 20, 2000 from two parties. The first was a letter of interest for the
government consulting business on a stand-alone basis.

        The second was a written proposal from PA Consulting Group, Inc. for an
all-cash acquisition of the company for consideration of $7.12 per share. PA
Consulting Group, Inc.'s proposal was contingent upon satisfactory completion of
further due diligence review of the company, the absence of any material adverse
change with respect to the company and its performance, execution of an
exclusive negotiation agreement and various other conditions.

       At a board of directors meeting on March 24, 2000, the board members
received a detailed briefing on the developments regarding the strategic
transaction discussions. The briefing also included a presentation by Banc of
America Securities regarding the following:

      o     an overview of the company's financial condition including a
            discussion of the viability of the business in the absence of a
            strategic transaction, reliability of our projected financial
            performance in light of the impact of potential consultant
            resignations, and lack of market interest in the company;

      o     a summary of marketing efforts by Banc of America Securities to
            solicit interest from potential strategic and financial partners,
            including a tally of parties solicited, initial indications of
            interest received and letters of interest received with respect to a
            potential strategic transaction;

      o     our stock price, historical trading ranges and stock performance
            relative to the selected market and peer group indices since our
            initial public offering in July 1997;

      o     a summary of analyst commentaries on the company's stock since 1998;

      o     a review of the institutional holdings in the company, including a
            discussion of the decrease or elimination of major institutional
            holdings since the first quarter of 1999;

      o     information with respect to our financial condition, financial
            projections, results of operation, cash flow and business prospects;
            and

      o     a preliminary valuation analysis for our common stock, including a
            comparable company analysis, precedent transaction analysis,
            discounted cash flow analysis and premiums analysis.

      The board of directors evaluated Banc of America Securities' presentation,
including its recommendation to pursue further negotiations with PA Consulting
Group, Inc., subject to certain conditions, and held discussions with management
regarding the future prospects of the company. Based on all the factors
presented, at the March 24, 2000 meeting, the board of directors concluded that
management should proceed with the merger discussions with PA Consulting Group,
Inc. and take all the necessary steps to conclude the merger transaction in a
speedy manner. The board of directors appointed a transaction team led by
Stephen V.R. Whitman, Senior Vice President and General Counsel, to negotiate
the definitive merger agreement.

      On March 29, 2000, members of our management, Jeremy Asher, Group Chief
Executive of PA Consulting Group, and representatives of Banc of America
Securities met at the company's offices to discuss and clarify certain terms of
PA Consulting Group, Inc.'s proposal. As a result of these discussions, PA
Consulting Group, Inc. submitted a revised written proposal to us in a letter
dated March 30, 2000 for an all-cash acquisition of the company for
consideration of $7.12 per share subject to possible downward adjustments
resulting from payments to certain executive officers, payments relating to the
earnout agreement and other matters that might arise as a result of further due
diligence.

      At a board of directors' meeting on March 31, 2000, Stephen V.R. Whitman
summarized the discussions with, and the terms of the revised proposal from, PA
Consulting Group, Inc. for the board of directors. The board of directors
reviewed and discussed the items in the revised proposal that could lead to
possible downward adjustments to the merger consideration. After further


                                       16
<PAGE>

deliberations, the board of directors authorized Mr. Whitman and the transaction
team to proceed with discussions with PA Consulting Group, Inc. on an exclusive
basis.

      On April 7, 2000, the company and PA Consulting Group, Inc. entered into
an exclusive negotiation agreement which provided for an exclusive negotiation
period between the parties through June 30, 2000. Between April 7, 2000 and June
18, 2000, our management, Banc of America Securities and PA Consulting Group,
Inc. continued to hold merger discussions regarding the deal structure, merger
agreement provisions, transaction timing, integration of the businesses,
employee matters and various other financial and operational matters. In
addition, during the same period, the company and PA Consulting Group, Inc.,
through respective counsel, exchanged drafts and negotiated the specific terms
of a proposed agreement and plan of merger, pursuant to which PA Consulting
Group, Inc. would acquire all of the company's outstanding capital stock and
stock options for cash.

      Concurrent with these merger discussions, management of the company held a
series of meetings and discussions with its board of directors to apprise them
of the merger discussions. During board of directors' meetings on April 20, 2000
and May 11, 2000, Stephen V.R. Whitman provided status reports to the board of
directors on the progress of the merger negotiations.

      On May 23, 2000, Henri-Claude Bailly, Geoffrey Bobsin, and Stephen V.R.
Whitman of the company met with Nick Hayes, Chief Financial Officer of PA
Consulting Group, to further discuss and negotiate various issues including the
merger consideration, future revenue stream, settlement with GKMG stockholders,
treatment of bonuses and the need to make additional retention bonuses available
to certain employees, retention of senior vice presidents and various other
business and operational matters.

      On June 2, 2000, Jeremy Asher and Nick Hayes of PA Consulting Group,
Geoffrey Bobsin and Stephen V.R. Whitman of the company, and representatives of
Banc of America Securities met to discuss various business and pricing issues.
Jeremy Asher and Nick Hayes reviewed the results of PA Consulting Group, Inc.'s
additional due diligence with the members of our management and expressed the
view that the total adjustments to the merger consideration identified to date
exceeded $2 per share. The parties then discussed in detail PA Consulting Group,
Inc.'s suggestion that this could decrease the merger consideration from $7.12
per share to a range between $3.50 and $5.00 per share. The potential
adjustments reflected, among other things, the contractual payments to Messrs.
Dickenson, Bailly and Pifer, earnout payments to the former GKMG stockholders,
payments of third and fourth quarter retention bonuses to employees and various
other payments and liabilities. In addition, the parties discussed the future
prospects of the environmental, telecommunications, energy and commercial
litigation practices and the potential adverse impact of loss of business in
such practices on the merger consideration. At a meeting on June 6, 2000,
members of the board of directors deliberated on the issues discussed at the
June 2, 2000 meeting.

      Subsequent to the discussions on June 2, 2000 there were numerous
telephone conversations between Geoffrey Bobsin and Jeremy Asher about the price
PA Consulting Group, Inc. would pay for the company. Managements of both the
company and PA Consulting Group, Inc. decided not to address and negotiate
separately each factor that might affect price but rather to negotiate the price
based on the overall condition of the company and its prospects. Henri-Claude
Bailly and Fred Schriever, an outside director of the company, also had
telephone discussions with Jeremy Asher during this time concerning the price to
be paid by PA Consulting Group, Inc. for the company.

      At a board of directors' meeting on June 14, 2000, Henri-Claude Bailly and
Geoffrey Bobsin gave a progress report on the status of negotiations with PA
Consulting Group, Inc. to the members of the board of directors. Messrs. Bailly
and Bobsin reported to the board of directors that PA


                                       17
<PAGE>

Consulting Group, Inc.'s offer was for $5.25 per share. After discussion, the
board of directors requested that Henri-Claude Bailly, Geoffrey Bobsin, Fred
Schriever and representatives of Banc of America Securities contact PA
Consulting Group, Inc. with a counteroffer of $5.35 per share. Ultimately the
managements of both the company and PA Consulting Group, Inc. agreed on a price
of $5.32 per share, subject to possible downward adjustments.

      In the afternoon of June 18, 2000, Banc of America Securities delivered an
updated presentation to the board of directors and indicated that it expected to
be in a position to render a fairness opinion, subject to review of the final
merger agreement. After further deliberations with respect to the terms of the
merger transaction, the board of directors determined that the merger with PA
Consulting Group, Inc. was fair and in the best interests of the stockholders
and approved the merger and authorized the execution of the merger agreement and
related agreements, substantially in the form presented to them at the meeting,
subject to resolution of certain pending issues and receipt of the final
fairness opinion from Banc of America Securities. The board of directors also
determined that the merger agreement be submitted to a vote of stockholders and
unanimously recommended that the stockholders approve and adopt the merger
agreement.

      During the evening of June 18, 2000, the management of the company and PA
Consulting Group, Inc. met for several hours and resolved all the pending issues
relating to the merger. On the morning of June 19, 2000, Banc of America
Securities delivered its oral fairness opinion to the board of directors
(subsequently confirmed by delivery of a written opinion dated June 19, 2000)
that as of such date and subject to the assumptions, limitations and
qualifications contained in the written opinion dated June 19, 2000, the
consideration to be received by stockholders pursuant to the merger agreement
was fair from a financial point of view to the stockholders. By unanimous
written consent effective June 19, 2000, the board of directors ratified and
approved the merger agreement.

      On June 19, 2000, each of the company, PA Consulting Group, Inc., PA
Holdings Inc. and PA Holdings Limited executed the merger agreement. The company
and PA Consulting Group then issued a joint press release announcing the
execution of the merger agreement.

Reasons for the Merger

      In making its decision to approve the merger agreement and to recommend to
the holders of common stock that they vote their shares in favor of adoption of
the merger agreement, the board of directors considered a number of factors,
including, among others, the following:

      o     the viability of the company's business in the absence of a
            strategic transaction in view of the potential significant loss of
            senior consultants, the difficulty in attracting market attention
            due to lack of equity coverage, lack of size and loss of credibility
            in the market, the difficult environment in which to restructure and
            gain momentum to regain market confidence, and the decline in
            operating margins and growth rate;

      o     the fact that no potential acquirors were identified that were
            prepared to make a proposal competitive to that of PA Consulting
            Group, Inc.;

      o     the recent decline in the company's earnings and its failure to meet
            analysts' projections for earnings for the first, second, third and
            fourth quarters in 1999 and first quarter of 2000, resulting in the
            need to revise earnings estimates downward;

      o     declines in the company's stock price from a 52-week high of $10.38
            to a 52-week low of $1.73;


                                       18
<PAGE>

      o     the current and prospective environment in which the company
            operates, including the loss of interest of the investment community
            in the management consulting industry and the dramatic decline in
            the price of the stock of several large publicly-traded management
            consulting firms;

      o     the relationship of the merger consideration to the historical and
            current market prices for the shares of our common stock preceding
            the announcement of the merger, including the fact that the merger
            price of $5.32 per share in cash (subject to possible downward
            adjustments) represents a premium of approximately 33% over the
            $4.00 per share closing price of the shares of the common stock on
            June 16, 2000, the last trading day before the announcement of the
            merger;

      o     disagreements among members of senior management regarding the
            direction and leadership of the company;

      o     presentations by Banc of America Securities and the opinion of Banc
            of America Securities that as of the date of, and subject to the
            assumptions, limitations and qualifications contained in, such
            opinion, the merger consideration was fair from a financial point of
            view to our stockholders;

      o     oral presentations by executive officers of the company regarding
            the business, financial condition and recent results of operations
            of the company, and their best estimates of the prospects of the
            company;

      o     the fact that the terms of the merger agreement were determined
            through arm's-length negotiations;

      o     the terms of the merger agreement as reviewed by the board of
            directors with its legal and financial advisors;

      o     the board of directors' assessment that PA Consulting Group, Inc.
            has the financial capability to acquire the company for the merger
            consideration and therefore is likely to consummate the merger,
            coupled with the fact that there are no financing conditions
            relating to the merger; and

      o     the board of directors' belief, after consultation with its legal
            counsel, that the required regulatory approvals for the merger could
            be obtained.

      In view of the variety of factors considered in connection with its
evaluation of the merger and the transactions contemplated by the merger
agreement, the board of directors did not quantify or otherwise assign relative
weights to the various factors that it considered or determine that any factor
was of particular importance in reaching its determination that the merger is
fair to and in the best interests of stockholders. In addition, individual
members of the board of directors may have given different weight to the
different factors.

Recommendation of the Board of Directors

      After careful consideration, our board of directors has unanimously
determined that the merger agreement and the merger are fair to and in the best
interests of the company and its stockholders. The board of directors
unanimously recommends that stockholders vote "FOR" approval of the merger
agreement and the merger.

Opinion of Hagler Bailly's Financial Advisor

      We retained Banc of America Securities on March 3, 1999 under a broad
mandate to assist the company in evaluating strategic alternatives, including
maximizing stockholder value through a possible sale transaction as well as to
help evaluate acquisition candidates.

      Banc of America Securities delivered an oral opinion, subsequently
confirmed in writing, to our board of directors on June 19, 2000 that, based
upon and subject to the assumptions, limitations and qualifications set forth in
the written opinion, the consideration to be received by our stockholders
pursuant to the merger agreement was fair, from a financial point of view, to
the company's stockholders.

      The full text of the written opinion of Banc of America Securities, dated
June 19, 2000, which sets forth assumptions made, general procedures followed,
matters considered and limitations on the review undertaken in connection with
the opinion, is attached as Appendix B to this proxy statement and is
incorporated herein by reference. You are urged to, and should, read the opinion
in its entirety. The opinion addresses only the consideration to be paid in the
merger transaction and is not a recommendation to any stockholder as to how that
stockholder should vote at the special meeting.

      For purposes of the opinion set forth herein, Banc of America Securities:

      o     reviewed certain publicly available financial statements and other
            business and financial information of the company;

      o     reviewed certain internal financial statements and other financial
            and operating data relating to the company;

      o     analyzed certain financial forecasts prepared in conjunction with
            the management of the company and considered the company's present
            financial condition;

      o     discussed the past and current operations, financial condition and
            prospects of the company with senior executives and members of the
            Board of Directors, including, without limitation, their belief that
            the company would suffer a potential significant loss of key
            consultants in the event that a strategic transaction did not occur
            in the near future;

      o     at the request of the board of directors, spoke with a number of
            potential purchasers concerning their possible interest in the
            company, and noted that no potential purchaser other than PA
            Consulting Group, Inc. presented a proposal to acquire the company;

      o     reviewed the reported prices and trading activity for the company's
            common stock;

      o     compared the financial performance of the company and the prices and
            trading activity of the company's common stock with that of certain
            other publicly traded companies Banc of America Securities deemed
            relevant;

      o     compared certain financial terms to financial terms, to the extent
            publicly available, of certain other business combination
            transactions Banc of America Securities deemed relevant;

      o     participated in discussions and negotiations among representatives
            of the company and PA Consulting Group, Inc. and their legal
            advisors;


                                       20
<PAGE>

      o     reviewed the merger agreement, including the form of earnout
            agreement attached as Schedule A to the merger agreement, and
            certain related documents; and

      o     performed such other analyses and considered such other factors as
            Banc of America Securities deemed appropriate.

      Banc of America Securities assumed and relied upon, without independent
verification, the accuracy and completeness of the financial and other
information reviewed by Banc of America Securities for the purposes of this
opinion, including the company's representation regarding the number of shares
and options outstanding. Banc of America Securities with management's consent
also assumed, and relied upon, the representations of management that it
believes that the earnout agreement (as described in the section entitled
"Related Agreements") would be executed on terms substantially similar to the
form thereof included in the merger agreement and any difference between the
actual earnout agreement and the form thereof included in the merger agreement
would not materially affect the consideration paid to the stockholders in the
merger. With respect to the financial forecasts, Banc of America Securities
assumed, and relied upon, without independent verification, the views of
management that they have been reasonably prepared on bases reflecting the best
currently available estimates and good faith judgments of the future financial
performance of the company. Banc of America Securities did not make any
independent valuation or appraisal of the assets or liabilities of the company,
nor had Banc of America Securities been furnished with any such appraisals.

      Banc of America Securities also held discussions with certain members of
the management of the company and PA Consulting Group, Inc. regarding numerous
aspects of the transaction, the past and current business operations of the
company, the financial condition and future prospects and operations of the
company, the effects of the transaction on the financial condition and prospects
of the company, and other matters that Banc of America Securities believed
necessary or appropriate to its inquiry. In addition, Banc of America Securities
reviewed other financial studies and analyses and considered other information
that it considered appropriate for the purposes of its opinion.

      The following is a summary of the financial analyses performed by Banc of
America Securities in connection with providing its written opinion attached as
Appendix B to this proxy statement. These descriptions of financial analyses
include information presented in tabular format. In order to fully understand
the financial analyses performed by Banc of America Securities, the tables must
be read together with the text of each description. The tables alone do not
constitute a complete description of such financial analyses. Considering the
data in the tables without considering the full narrative description of the
financial analyses, including the methodologies and assumptions underlying the
analyses, could create a misleading or incomplete view of the financial analyses
performed by Banc of America Securities.

      Analysis of Selected Publicly Traded Companies. Based on public and other
available information, Banc of America Securities calculated the multiples of
aggregate value, which Banc of America Securities defined as equity value plus
debt, less cash and cash equivalents, to revenues, earnings before interest,
taxes, depreciation and amortization ("EBITDA") and earnings before interest and
taxes ("EBIT") covering the latest twelve months ("LTM"), projected 2000
("2000P") and projected 2001 ("2001P"), where available. Based on public and
other available information, Banc of America Securities also calculated the
multiples of current stock price to LTM and projected earnings per share ("EPS")
for fiscal years 2000 and 2001, where available. Banc of America Securities
calculated these multiples for six companies in the management consulting sector
whose securities are publicly traded. Banc of America Securities analyzed
Charles River Associates Inc., Maximus, Inc., Navigant Consulting, Inc., Nextera
Enterprises, Inc., Superior Consultant Holdings Corp. and Tetra Tech, Inc. (the
"Banc of America Securities Selected Companies"). Banc of America Securities
believes that these six companies in the management consulting sector have
operations


                                       21
<PAGE>

similar to some of the operations of the company, but noted that none of these
companies has the same management, composition, size or combination of
businesses as the company.

      The following table presents information concerning the range, averages
and medians of multiples for the Banc of America Securities Selected Companies:

-------------------------------------------------------------------------------
                                  Range of Multiples

-------------------------------------------------------------------------------
2000P EBIT                      6.7x      -      13.5x        9.2x        8.3x
-------------------------------------------------------------------------------
2001P EBIT                      2.1x      -      11.2x        6.0x        5.8x
-------------------------------------------------------------------------------
Current Stock Price to:
-------------------------------------------------------------------------------
LTM EPS                        14.5x      -      25.2x       19.4x       19.0x
-------------------------------------------------------------------------------
2000P EPS                      12.6x      -      22.8x       15.9x       14.2x
-------------------------------------------------------------------------------
2001P EPS                      10.0x      -      18.7x       12.1x       10.5x
-------------------------------------------------------------------------------

      Banc of America Securities noted that the aggregate value of the
consideration to be paid by PA Consulting Group, Inc. in connection with the
transaction implied multiples of 0.61x LTM gross revenue, 0.84x 2000P gross
revenue, 0.90x 2001P gross revenue, 7.0x LTM EBITDA, 8.6x 2000P EBITDA, 9.6x
2001P EBITDA, 10.7x LTM EBIT, 14.0x 2000P EBIT and 17.5x 2001P EBIT. The offer
price of $5.32 per share of company common stock, subject to downward adjustment
pursuant to the merger agreement, to be paid in the transaction implied
multiples of 16.0x LTM EPS, 21.1x 2000P EPS and 27.7x 2001P EPS. LTM data is
largely misleading in the company's case because of the projected significant
loss of senior consultants throughout 2000 in the event that a strategic
transaction is not consummated. As a result, application of LTM multiples
largely overstates the implied per share value of the company as these results
are based on a higher billing capacity relative to the company's projected
billing capacity.

      Analysis of Selected Acquisitions. Banc of America Securities analyzed
information relating to the following selected transactions in the management
consulting sector above a $50 million aggregate value which became effective
between August 6, 1997 and March 10, 2000, collectively referred to as the "Banc
of America Securities Selected Transactions":

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

      Based on public and other available information, Banc of America
Securities calculated the multiples for the Banc of America Securities Selected
Transactions of (a) aggregate value to gross revenue (in those transactions
where publicly available data did not confirm whether the disclosed revenue
figures were stated on a gross or net basis, Banc of America Securities
conservatively assumed that such statistics were gross revenue figures), EBITDA
and EBIT and (b) equity value to net income in each case for the acquired
business in the twelve months preceding the acquisition announcements. The
following table sets forth the range, averages and medians of the Banc of
America Securities Selected Transactions:

---------------------------------------------------------------------------
                           Range of Multiples
Aggregate Value to:       Low             High       Average        Median
---------------------------------------------------------------------------
LTM Gross Revenue        0.75x     -      5.01x       2.27x          1.82x
---------------------------------------------------------------------------
LTM EBITDA                9.3x     -      24.9x       17.1x          17.1x
---------------------------------------------------------------------------
LTM EBIT                  8.8x     -      27.1x       15.5x          10.5x

Equity Value to:

LTM Net Income           15.2x     -      31.3x       23.2x          23.2x
---------------------------------------------------------------------------

      As previously discussed, LTM data is largely misleading in the company's
case because of the projected significant loss of senior consultants throughout
2000 in the event that a strategic transaction is not consummated.

      No company or transaction used in the comparable company or comparable
transactions analyses is identical to the company or the merger transaction,
respectively. Accordingly, an analysis of the results of the foregoing is not
merely a mathematical exercise, but rather involves complex considerations and
judgments concerning differences in financial and operating characteristics of
the companies and other factors that could affect the public trading value or
purchase price of the companies to which the company and the merger transaction
are being compared.

      Discounted Cash Flow Analysis. Banc of America Securities performed a
discounted cash flow analysis by using financial cash flow forecasts of the
company for fiscal years 2000 through 2004 prepared in conjunction with the
management of the company. In conducting this analysis, Banc of America
Securities assumed that the company would perform in accordance with these
forecasts. Banc of America Securities first estimated the terminal value of the
projected cash flows by applying multiples to the company's projected 2004
EBITDA, which multiples ranged from 6.0x to 8.0x. Banc of America Securities
then discounted the cash flows projected through 2004 and the terminal values to
present values using rates ranging from 13.0% to 15.0%. This analysis indicated
a range of aggregate values, which were then reduced by the company's net debt
as of May 31, 2000


                                       23
<PAGE>

(which, for purposes of analyses conducted by Banc of America Securities,
included the estimated present value of obligations to be assumed by PA
Consulting Group, Inc. using a 21.0% discount rate), to calculate a range of
equity values. These equity values were then divided by fully diluted shares to
calculate implied equity values per share ranging from $3.87 to $5.18. Banc of
America Securities noted that the value of consideration to be received in
connection with the merger transaction was $5.32 per share, subject to downward
adjustment pursuant to the merger agreement.

      Premiums Paid Analysis. Banc of America Securities analyzed the premiums
paid in 81 U.S. acquisitions announced since January 1, 1999 in which 100% of
the target's stock was purchased with cash and that had an aggregate value
between $50 to $150 million. Banc of America Securities calculated the premiums
paid one day and four weeks prior to the announcement of the acquisition offer.
The following table sets forth the average and median premiums paid in these
transactions:

--------------------------------------------------------------
                        Premium One Day        Premium 4 Weeks

      Banc of America Securities noted that the value of the cash consideration
in connection with the merger transaction implied a premium of 33.0% over the
company's share price of $4.00 at the close of trading on June 16, 2000, and a
64.2% premium over the company's three-month average share price of $3.24 as of
the same date.

      The foregoing description is only a summary of the analyses and
examinations that Banc of America Securities deems material to its opinion. It
is not a comprehensive description of all analyses and examinations actually
conducted by Banc of America Securities and is qualified by reference to the
written opinion of Banc of America Securities set forth in Appendix B to this
proxy statement. The preparation of a fairness opinion necessarily is not
susceptible to partial analysis or summary description. Banc of America
Securities believes that its analyses and the summary set forth above must be
considered as a whole. Banc of America Securities further believes that
selecting portions of its analyses and of the factors considered, without
considering all analyses and factors, would create an incomplete view of the
process underlying the analyses set forth in its presentation to the board of
directors. In addition, Banc of America Securities may have given various
analyses more or less weight than other analyses, and may have deemed various
assumptions more or less probable than other assumptions. The fact that any
specific analysis has been referred to in the summary above is not meant to
indicate that such analysis was given greater weight than any other analysis.
Accordingly, the ranges of valuations resulting from any particular analysis
described above should not be taken to be Banc of America Securities' view of
the actual value of the company.

        In performing its analyses, Banc of America Securities made numerous
assumptions with respect to industry performance, general business and economic
conditions and other matters, many of which are beyond the control of the
company and PA Consulting Group, Inc. The analyses performed by Banc of America
Securities are not necessarily indicative of actual values or actual future
results, which may be significantly more or less favorable than those suggested
by these analyses. These analyses were prepared solely as part of Banc of
America Securities' analysis of the financial fairness of the consideration to
be paid by PA Consulting Group, Inc. for the acquisition of the company and were
provided to the board of directors in connection with the delivery of its
opinion. The analyses do not purport to be appraisals or to reflect the prices
at which a company might actually be sold or the prices at which any securities
may trade at any time in the future.

      As described above, Banc of America Securities' opinion and presentation
to the board of directors were among the many factors taken into consideration
by the board of directors in making its determination to approve the merger
agreement.

      The company engaged Banc of America Securities to act as its financial
advisor under an agreement dated March 3, 1999 as amended on October 5, 2000.
Under this agreement, the company will pay Banc of America Securities a fee of
$1.5 million. We have also agreed to reimburse Banc of America Securities for
its reasonable out-of-pocket expenses, including reasonable fees and expenses of
counsel, and to indemnify Banc of America Securities and related persons against
certain liabilities, including, without limitation, liabilities under federal
securities laws arising out of Banc of America Securities' engagement.

      In the ordinary course of its business, Banc of America Securities may
actively trade the equity securities of the company for its own account and for
the accounts of customers and, accordingly, may at any time hold a long or short
position in such securities.

      Banc of America Securities, as part of its investment banking business, is
continually engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions, negotiated underwritings, competitive
biddings, secondary distributions of listed and unlisted securities, private
placements and valuations for estate, corporate and other purposes. Banc of
America Securities was selected by the company as its financial advisor with
respect to the merger transaction on the basis of its experience and familiarity
with the company.

Interests of Certain Persons in the Merger

      In considering the recommendation of the board of directors with respect
to the merger, you should be aware that certain directors and executive officers
of the company have interests in the merger that are different from, or are in
addition to, yours.

      Agreements With Certain Executive Officers and Former Executive Officers
and Directors. The company had an employment agreement with each of Messrs.
Bailly, Dickenson and Pifer. Pursuant to each of the employment agreements, upon
a change in control as defined in the employment agreement, each of Messrs.
Bailly, Dickenson and Pifer would be entitled to certain payments.

      The definition of change in control in the employment agreements includes
when, other than as a result of death, disability or termination for cause, (x)
Mr. Dickenson shall cease to serve as chief executive officer of PHB Hagler
Bailly or as executive vice president and chief operating officer of the company
before January 1, 2000, or after January 1, 2000, as chief executive officer of
the company or as a member of the company's board of directors; (y) Dr. Pifer
shall cease to serve as chairman of the company's board of directors before
January 1, 2000, or as a member of the company's board of directors; or (z) Mr.
Bailly shall cease to serve as chief executive officer of the company before
January 1, 2000, or after January 1, 2000, as chairman of the company's board of
directors. In addition, the definition includes (i) certain changes in ownership
of the stock of the company (in connection with a merger or other corporate
reorganization or otherwise) and (ii) a sale of all or substantially all of the
assets of the company or dissolution or liquidation of the company.

      On March 31, 1999, the company's board of directors elected Mr. Dickenson
president and chief executive officer of the company. At the same time, the
board of directors determined that Mr. Bailly would become chairman of the board
of directors on September 1, 1999. Dr. Pifer served as chairman of the board of
directors until September 1, 1999. Each of Messrs. Bailly, Pifer and Dickenson
construed the board of directors' actions on March 31, 1999 to have caused a
change in


                                       25
<PAGE>

control of the company within the meaning of that term under their respective
employment agreements. Each of Messrs. Bailly, Dickenson and Pifer, in a
separate letter dated April 7, 1999, determined not to exercise his right to
terminate his employment agreement as a result of the board of directors' action
on March 31, 1999 for so long as the other two individuals exercised such powers
and performed such duties as are set forth for their respective offices in the
then current by-laws of the company.

            William E. Dickenson. On May 11, 2000, Mr. William E. Dickenson
resigned as president, chief executive officer and a member of the board of
directors of the company. On May 3, 2000, the company entered into an Employment
Separation Agreement and General Release with Mr. Dickenson, pursuant to which
the company paid Mr. Dickenson a lump-sum amount of $2.376 million on May 11,
2000.

            Mr. Dickenson's resignation constituted a change in control as
defined in the respective employment agreements of Mr. Bailly and Dr. Pifer,
thereby granting the right to Mr. Bailly and Dr. Pifer to terminate their
respective employment agreements and to receive the payments described below.
Moreover, since Mr. Dickenson ceased to carry out his duties as president and
chief executive officer on May 11, 2000, Mr. Bailly construed such event to
relieve him from the obligation, if any, to continue to refrain, in accordance
with his letter of April 7, 1999, from exercising his right to terminate his
employment agreement as a result of the board of directors' actions of March 31,
1999. Mr. Bailly construed that the right to terminate his employment agreement
and to receive certain payments thereunder as having vested on March 31, 1999.
The terminations of Mr. Bailly's and Dr. Pifer's respective employment
agreements are unrelated to the merger, the merger agreement or the board of
directors' recommendation relating to the merger.

            Howard W. Pifer, III. On May 12, 2000, Dr. Pifer terminated his
employment agreement with the company. On June 9, 2000, the company paid Dr.
Pifer a lump-sum amount of $1,526,304. Pursuant to the terms of his employment
agreement, Dr. Pifer will receive semi-monthly payments for a period of
thirty-six (36) months commencing on May 12, 2000, at an annual rate of
$381,576. On May 25, 2000, the company entered into an agreement with Dr. Pifer
pursuant to which Dr. Pifer will serve as a senior advisor to the company. Dr.
Pifer resigned as a member of the board of directors of the company on July 5,
2000.

            Henri-Claude A. Bailly. On July 3, 2000, Mr. Bailly terminated his
employment agreement with the company. On August 2, 2000, the company will pay
Mr. Bailly a lump-sum amount of $1,737,616. Pursuant to the terms of his
employment agreement, Mr. Bailly will receive semi-monthly payments for a period
of thirty-six (36) months commencing on July 3, 2000, at an annual rate of
$434,404. Mr. Bailly remains as an executive officer of the company with the
title of chairman of the board of directors.

            Geoffrey W. Bobsin. The company has an employment agreement with
Geoffrey W. Bobsin dated as of October 20, 1999, as amended on February 29, 2000
and May 31, 2000, pursuant to which Mr. Bobsin will, as of May 11, 2000, serve
as president and chief executive officer of the company. Mr. Bobsin's agreement
will terminate on March 31, 2001, unless terminated earlier in accordance with
the terms of the agreement. Under the agreement, Mr. Bobsin receives a base
salary, as of May 10, 2000, at an annual rate of $363,480. Mr. Bobsin is also
entitled to a bonus payment for the calendar year 2000 in the aggregate amount
of $122,500, payable in several installments. Mr. Bobsin is also entitled to
participate in all of the benefit programs provided by the company. Upon a
change in control of the company as defined in the employment agreement, Mr.
Bobsin is entitled to an additional amount of $102,500, as well as the payment
of any unpaid installments of his calendar year 2000 bonus.

            Stephen V.R. Whitman. The company has an employment agreement with
Stephen V.R. Whitman dated as of May 31, 2000, pursuant to which Mr. Whitman
will serve as Senior Vice


                                       26
<PAGE>

President and General Counsel of the company. Mr. Whitman's agreement will
terminate on March 31, 2001, unless terminated earlier in accordance with the
terms of the agreement. Under the agreement, Mr. Whitman receives a base salary
at an annual rate of $225,264. Mr. Whitman is also entitled to a bonus payment
for the calendar year 2000 in the aggregate amount of $122,500, payable in
several installments. Mr. Whitman is also entitled to participate in all of the
benefit programs provided by the company. Upon a change in control of the
company as defined in the employment agreement, Mr. Whitman is entitled to an
additional amount of $102,500, as well as the payment of any unpaid installments
of his calendar year 2000 bonus.

      Certain directors and officers of the company have entered into a voting
agreement with PA Consulting Group, Inc. and PA Holdings Inc., pursuant to which
they have agreed to vote all of their shares of common stock (i) in favor of the
merger and the adoption of the merger agreement and the transactions
contemplated thereby; (ii) against approval or adoption of resolutions which
would prevent or materially delay the company from performing its obligations
under the merger agreement; and (iii) against any action which would constitute
a material breach of any provision of the merger agreement. See "Related
Agreements -- The Voting Agreement". As a result of the interests described
above, these directors and officers may have been more likely to enter into the
voting agreement requiring them to vote in favor of approving the merger
agreement and the merger than if they did not have these interests.

      Stock Options. Under the merger agreement, at the effective time of the
merger, each option to purchase a share of the company's common stock
outstanding and unexercised as of the effective time of the merger granted
pursuant to the Hagler Bailly Employee Incentive and Non-Qualified Stock Option
and Restricted Stock Plan will be canceled, whether or not then exercisable or
vested.

      With respect to options which are vested and have an exercise price of
less than $5.32, PA Consulting Group, Inc. will pay an amount per option equal
to the excess of $5.32 (as may be adjusted) over each option's per share
exercise price (the "option spread") to the holders of such options.

      With respect to options which have an exercise price equal to or greater
than $5.32 per share, PA Consulting Group, Inc. will pay an amount per option
grant equal to $1.00 (or a lesser amount if the total number of grants of
out-of-the-money options is greater than 2,000) multiplied by the total number
of grants of out-of-the-money options to such optionholder. To the extent that
the number of grants of out-of-the-money options exceeds 2,000, the amount to be
received by each optionholder per grant will be reduced pro rata so that in the
aggregate the consideration paid to holders of out-of-the-money options does not
exceed $2,000.

      With respect to any option which is not, as of the effective time of the
merger, vested, but which has an exercise price of less than $5.32, PA
Consulting Group, Inc. will pay to the optionholder the option spread as soon as
practicable after the date when (but only if) such option would otherwise have
vested if such option had not been canceled.

      As of July 7, 2000, directors, executive officers and other employees held
in the aggregate (i) 137,501 in-the-money options and (ii) 2,707,342
out-of-the-money options for a total amount of 2,844,843 options outstanding.

      Indemnification of Directors and Officers. Under the merger agreement, PA
Consulting Group, Inc. has agreed that it will not, for a period of six years
after the effective time of the merger, amend the surviving corporation's
certificate of incorporation or bylaws in any manner that would adversely affect
the rights of persons who at any time prior to the effective time of the merger
were identified as prospective indemnitees in respect of actions or omissions
occurring at or prior to the effective time of the merger, unless such amendment
is required by law. In addition, the merger agreement provides that the
surviving corporation will, after the effective time of the


                                       27
<PAGE>

merger and to the extent permitted by Delaware law, indemnify, defend and hold
harmless the present and former officers, directors and employees of the company
and its subsidiaries against all losses, expenses, claims, damages, liabilities
or amounts that are paid in settlement of, with the approval of PA Consulting
Group, Inc., and the surviving corporation, or otherwise in connection with, any
claim, action, suit, proceeding or investigation based in whole or in part on
the fact that such person is or was such a director, officer or employee and
arising out of actions or omissions occurring at or prior to the effective time
of the merger. PA Consulting Group, Inc. has also agreed to cause to be
maintained in effect for not less than six years after the effective time of the
merger the current policies of directors' and officers' liability insurance and
fiduciary liability insurance maintained by the company (or substitute policies
with substantially the same coverage and terms) with respect to matters
occurring prior to the effective time of the merger except that PA Consulting
Group, Inc. shall not be required to pay an annual premium for such insurance of
more than 200% of the last annual premium paid prior to the date of the merger
agreement.

Merger Financing

      The total amount of funds required to pay the merger consideration is
estimated to be approximately $95.4 million. PA Holdings Limited will ensure
that PA Consulting Group, Inc. has sufficient funds to pay the merger
consideration and will provide for such funds from PA Holdings Limited's
available cash or lines of credit. Approximately $319,280 will be required to
pay holders of outstanding options upon cancellation of such options.

Regulatory Approvals

      The merger is subject to the requirements of the Hart-Scott-Rodino
Antitrust Improvements Act (the "HSR Act"), which prevents certain transactions
from being completed until required information and materials are furnished to
the Antitrust Division of the Department of Justice and the Federal Trade
Commission and the appropriate waiting periods expire without objection. On July
7, 2000, the company and PA Consulting Group, Inc. each filed the required
information and materials with the Department of Justice and the Federal Trade
Commission. The applicable waiting period has terminated.

      At any time before of after the merger becomes effective, the Antitrust
Division, the Federal Trade Commission, state antitrust authorities or a private
person or entity could seek to enjoin the merger or to seek divestiture of
substantial assets of the company, PA Consulting Group, Inc., or their
subsidiaries. A challenge to the merger could be made, and if a challenge is
made, we may not prevail.

      The company is not aware of any other material governmental or regulatory
approval required for completion of the merger, other than compliance with the
applicable corporate law of Delaware.

Certain Federal Income Tax Consequences of the Merger

      The following discussion describes certain United States federal income
tax consequences of the merger. The discussion is based upon the Internal
Revenue Code of 1986, as amended, existing and proposed Treasury regulations,
rulings, administrative pronouncements and judicial decisions, changes to which
could materially affect the tax consequences described in this proxy statement
and could be made on a retroactive basis. This discussion does not address all
aspects of federal income taxation that may be important to you based on your
particular circumstances and does not address any aspect of state, local or
foreign tax laws. This summary generally considers only shares of common stock
that are held as capital assets (generally, assets held for investment) and may
not apply to holders who are subject to special treatment under the Internal
Revenue Code, including,


                                       28
<PAGE>

without limitation, financial institutions or trusts; tax-exempt entities;
insurance companies; dealers in securities or foreign currencies; stockholders
who received their shares of common stock through an exercise of employee stock
options or otherwise as compensation; stockholders who are foreign corporations,
foreign partnerships or other foreign entities, or individuals who are not
citizens or residents of the U.S.; and holders that hold common stock as part of
a "straddle," "hedge" or "conversion transaction."

      For federal income tax purposes, the merger will be treated as a taxable
purchase of stock by PA Consulting Group, Inc. from the stockholders. A holder
of common stock will recognize taxable gain or loss equal to the difference
between the amount of cash received in the merger and such holder's adjusted tax
basis in the shares of common stock exchanged. Such gain or loss will generally
be capital gain or loss and will be long-term capital gain or loss if at the
effective time of the merger, the holder has a holding period for the common
stock of more than one year.

      Payments of cash to a holder surrendering shares of common stock will be
subject to information reporting and "backup" withholding at a rate of 31% of
the cash payable to the holder, unless the holder furnishes its taxpayer
identification number in the manner prescribed in applicable treasury
regulations, certifies that such number is correct, certifies as to no loss of
exemption from backup withholding and meets certain other conditions. Any
amounts withheld from payments to a holder under the backup withholding rules
generally will be allowed as a credit against the holder's United States federal
income tax liability, which may entitle such holder to a refund provided the
required information is furnished to the Internal Revenue Service.

      No ruling has been requested from the Internal Revenue Service as to any
of the tax effects to stockholders of the transactions discussed in this proxy
statement, and no opinion of counsel has or will be rendered to stockholders
with respect to any of the tax effects of the merger or the other related
transactions.

      THE PRECEDING DISCUSSION DOES NOT PURPORT TO BE A COMPLETE ANALYSIS OR
DISCUSSION OF ALL POTENTIAL TAX EFFECTS RELEVANT TO THE MERGER. STOCKHOLDERS ARE
URGED TO CONSULT THEIR OWN TAX ADVISORS AS TO THE SPECIFIC TAX CONSEQUENCES TO
THEM (INCLUDING THE APPLICABILITY AND EFFECT OF ANY FEDERAL, STATE, LOCAL,
FOREIGN AND OTHER TAX LAWS AND THE EFFECT OF ANY PROPOSED CHANGES IN THE TAX
LAWS) OF THE MERGER.

Accounting Treatment of the Merger

      The merger will be treated as a purchase for accounting purposes under
generally accepted accounting principles.

Appraisal Rights of Dissenting Stockholders

      If you are a stockholder who does not vote in favor of the merger
agreement and who properly demands appraisal of your shares of common stock, you
will be entitled to appraisal rights in connection with the merger under Section
262 of the Delaware General Corporation Law.

      The following discussion only applies to stockholders who wish to dissent
from the merger. Only a holder of record of shares may exercise appraisal
rights.

      The following discussion is not a complete statement of the law pertaining
to appraisal rights under the Delaware General Corporation Law and is qualified
in its entirety by the full text of Section 262 which is attached as Appendix C
to this proxy statement. All references in Section 262 and in this summary to a
stockholder are to the


                                       29
<PAGE>

record holder of the shares as to which appraisal rights are asserted. A person
having a beneficial interest in shares held of record in the name of another
person, such as a broker or nominee, must act promptly to cause the record
holder to follow the steps summarized below in a proper and timely manner to
perfect appraisal rights.

      Under the Delaware General Corporation Law, if you follow the procedures
set forth in Section 262, you will be entitled to have your shares appraised by
the Delaware Court of Chancery and to receive payment of the fair value of your
shares, exclusive of any element of value arising from the accomplishment or
expectation of the merger, together with a fair rate of interest, as determined
by the Court.

      Under Section 262, where a proposed merger is to be submitted for approval
at a meeting of stockholders, as in the case of the special meeting, the
corporation, not less than 20 days prior to the meeting, must notify each of its
stockholders entitled to appraisal rights that appraisal rights are available
and include in the notice a copy of Section 262. This proxy statement will
constitute such notice to the stockholders, and the applicable statutory
provisions are attached as Appendix C to this proxy statement. If you wish to
exercise appraisal rights or to preserve your right to do so, you should review
the following discussion and Appendix C carefully. If you fail to timely and
properly comply with the procedures specified, you will lose your appraisal
rights.

      If you wish to exercise appraisal rights, you must:

            o     deliver to the company, before the vote on the merger at the
                  special meeting, a written demand for appraisal;

            o     not vote in favor of the merger; and

            o     continuously hold of record your shares from the date of
                  delivering a demand for appraisal through the effective time
                  of the merger.

      To not vote in favor of the merger, you can either (a) vote "no" in person
or by proxy, (b) fail to vote or (c) abstain from voting. However, if you vote
in favor of the merger agreement, by proxy or in person, or return a signed
proxy that does not contain voting instructions and do not revoke it, you will
waive your right of appraisal and nullify any previously filed written demand
for appraisal. A vote against the merger, in person or by proxy, will not in and
of itself constitute a written demand for appraisal satisfying the requirements
of Section 262. If you fail to comply with any of these conditions and the
merger becomes effective, you will lose your appraisal rights and receive
instead the merger consideration you are entitled to in accordance with the
merger agreement.

      Only a holder of record of shares may assert appraisal rights for the
shares registered in his or her name. A demand for appraisal should be executed
by or on behalf of the holder of record, fully and correctly, as the holder of
record's name appears on the stock certificates. It must also state that the
holder of record intends to demand appraisal of his or her shares in connection
with the merger. If the shares are owned of record in a fiduciary capacity, such
as by a trustee, guardian or custodian, execution of the demand should be made
in that capacity. If the shares are owned of record by more than one person, as
in a joint tenancy and tenancy in common, the demand should be executed by or on
behalf of all joint owners. An authorized agent, including two or more joint
owners, may execute a demand for appraisal on behalf of a holder of record.
However, the agent must identify the record owner or owners and expressly
disclose the fact that, in executing the demand, the agent is agent for such
owner or owners.

      A record holder such as a broker who holds shares as nominee for several
beneficial owners may exercise appraisal rights with respect to the shares held
for one or more beneficial owners without exercising appraisal rights with
respect to the shares held for other beneficial owners. If you hold your shares
in brokerage accounts or other nominee forms and wish to exercise appraisal


                                       30
<PAGE>

rights, you should consult your broker to determine the appropriate procedures
for making a demand for appraisal.

      All written demands for appraisal under Section 262 should be sent or
delivered to Hagler Bailly, Inc., 1530 Wilson Boulevard, Suite 400, Arlington,
Virginia 22209, Attention: Corporate Secretary.

      Within 10 days after the effective time of the merger, the surviving
corporation of the merger must notify each holder of shares who has complied
with Section 262 and has not voted in favor of or consented to the merger of the
date that the merger has become effective. At any time within 60 days after the
effective time of the merger, you have the right to withdraw your demand for
appraisal and to accept the consideration offered in the merger. Within 120 days
after the effective time of the merger, but not after that time, the surviving
corporation of the merger or any holder of shares who is entitled to appraisal
rights may file a petition in the Delaware Court of Chancery demanding a
determination of the fair value of the dissenting shares. The surviving
corporation of the merger is under no obligation to file this petition and PA
Consulting Group, Inc. has no present intention to cause the surviving
corporation of the merger to do so. Accordingly, it is the obligation of the
holders of shares to initiate all necessary action to perfect appraisal rights
within the time prescribed in Section 262.

      Within 120 days after the effective time of the merger, if you have
complied with the requirements for exercise of appraisal rights, you will be
entitled, upon written request, to receive from the surviving corporation of the
merger a statement setting forth the aggregate number of shares not voted in
favor of the merger as to which demands for appraisal have been received and the
aggregate number of holders of those shares. The surviving corporation of the
merger must mail this statement to you within 10 days after it receives a
written request from you or within 10 days after the expiration of the period
for delivery of demands for appraisal, whichever is later.

      If a petition for an appraisal is timely filed by a holder of shares and a
copy is served upon the surviving corporation of the merger, the surviving
corporation of the merger will then be obligated within 20 days to file with the
Delaware Register in Chancery a duly verified list containing the names and
addresses of all holders of shares who have demanded an appraisal of their
shares and with whom agreements as to the value of their shares have not been
reached. After notice to these stockholders as required by the Court, the
Delaware Court of Chancery may conduct a hearing on this petition to determine
those holders of shares who have complied with Section 262 and who have become
entitled to appraisal rights. The Delaware Court of Chancery may require the
holders of shares who demanded appraisal to submit their stock certificates to
the Register in Chancery for notation of the pendency of the appraisal
proceeding. If you fail to comply with this direction, the Court of Chancery may
dismiss the proceedings as to you.

      After determining the holders of shares entitled to appraisal, the
Delaware Court of Chancery will appraise the fair value of their shares,
exclusive of any element of value arising from the accomplishment or expectation
of the merger, together with a fair rate of interest, if any, to be paid upon
the amount determined to be the fair value. You should be aware that the fair
value of your shares as determined by Section 262 could be more than, the same
as or less than the consideration you would receive in the merger if you did not
seek appraisal of your shares.

      Section 262 provides that fair value is to be "exclusive of any element of
value arising from the accomplishment or expectation of the merger." The
Delaware Supreme Court has stated, in Cede & Co. v. Technicolor, Inc., 684 A.2d
289, 299 (Del. 1996), that this "narrow exclusion does not encompass known
elements of value, including those which exist on the date of the merger because
of a majority acquiror's interim acquisition in a two-step cash-out
transaction." In Weinberger v.

Uop, Inc., 457 A.2d 701 (Del. 1983), the Delaware Supreme Court held that
"elements of future value, including the nature of the enterprise, which are
known or susceptible of proof as of the date of the merger and not the product
of speculation, may be considered." The Delaware Supreme Court has stated that
"proof of value by any techniques or methods which are generally considered
acceptable in the financial community and otherwise admissible in court" should
be considered in the appraisal proceedings.

      In addition, Delaware courts have decided that the statutory appraisal
remedy, depending on factual circumstances, may or may not be a dissenter's
exclusive remedy. The Court of Chancery will also determine the amount of
interest, if any, to be paid upon the amounts to be received by persons whose
shares have been appraised. The costs of the action may be determined by the
Court and taxed upon the parties as the Court deems equitable. Upon application
by a stockholder, the Court may also order that all or a portion of the expenses
incurred by any stockholder in connection with an appraisal, including, without
limitation, reasonable attorneys' fees and the fees and expenses of experts
utilized in the appraisal proceeding, be charged pro rata against the value of
all the shares entitled to be appraised.

      If you have duly demanded an appraisal in compliance with Section 262, you
will not, after the effective time of the merger, be entitled to vote your
shares for any purpose or be entitled to the payment of dividends or other
distributions on those shares, except dividends or other distributions payable
to holders of record of shares as of a date prior to the effective time of the
merger.

      If you demand appraisal of your shares under Section 262 but fail to
perfect, or effectively withdraw or lose, your right to appraisal, your shares
will be converted into the right to receive the merger consideration you are
entitled to under the merger agreement, without interest. You will fail to
perfect, or effectively lose or withdraw, your right to appraisal if no petition
for appraisal is filed within 120 days after the effective time of the merger,
or if you deliver to the surviving corporation of the merger a written
withdrawal of your demand for appraisal and an acceptance of the merger.
However, any attempt to withdraw made more than 60 days after the effective time
of the merger will require the written approval of the surviving corporation of
the merger and, once a petition for appraisal is filed, the appraisal proceeding
may not be dismissed as to any holder absent court approval. It is not necessary
that each holder of shares properly demanding appraisal file a petition for
appraisal in the Delaware Court of Chancery. Rather, a single valid petition
suffices for the petitioning and non-petitioning holders of shares who have
properly demanded appraisal.

      If you fail to follow the steps required by Section 262 of the Delaware
General Corporation Law for perfecting appraisal rights, you may lose these
rights. In that case, you will receive the merger consideration you are entitled
to in accordance with the merger agreement.

                              THE MERGER AGREEMENT

      The following is a summary of the material terms and provisions of the
merger agreement. This summary does not purport to describe all the terms of the
merger agreement and is qualified in its entirety by reference to the merger
agreement which is attached as Appendix A to this proxy statement and is
incorporated by reference. You are urged to read the merger agreement carefully
and in its entirety.

Structure and Effectiveness of the Merger

      In the merger, PA Holdings Inc., an indirect wholly-owned subsidiary of PA
Holdings Limited, will merge with and into the company. As a result of the
merger, the separate corporate existence of PA Holdings Inc. will cease and the
company will survive the merger as an indirect wholly-owned subsidiary of PA
Holdings Limited.

      The merger will be completed when all of the conditions to completion of
the merger are satisfied or waived. This includes approval and adoption of the
merger agreement by our stockholders. Approval and adoption of the merger
agreement will also constitute approval of the merger and the other transactions
contemplated by the merger agreement. The merger will become effective upon the
filing of a certificate of merger with the Secretary of State of the State of
Delaware.

Conversion of Common Stock

      At the effective time of the merger, without any further action on the
part of PA Holdings Inc., the company or the holders of any securities of the
company:

      o     all shares of the company's common stock held in the treasury or
            owned by PA Consulting Group, Inc., or any of its subsidiaries, or
            PA Holdings Inc. will be canceled and no consideration will be
            delivered for the shares; and

      o     each other share of the company common stock issued and outstanding
            prior to the effective time of the merger (other than shares as to
            which dissenters' rights of appraisal have been perfected) will be
            converted into the right to receive $5.32 in cash (subject to
            possible downward adjustments). If the number of outstanding shares
            of our common stock or the number of in-the-money options to
            purchase our common stock are greater than as set forth in the
            merger agreement, the purchase price per share will be adjusted
            downward so that the total consideration paid by PA Consulting
            Group, Inc. to stockholders and optionholders stays the same.
            Management believes that the number of shares and in-the-money
            options is correctly set forth in the merger agreement and that an
            adjustment will not be made to the purchase price. Upon
            effectiveness of the merger, all shares of the company's common
            stock will no longer be outstanding and will automatically be
            canceled and retired and each holder of a certificate representing
            any of these shares shall cease to have any rights as a stockholder
            except the right to receive the merger consideration.

Treatment of Stock Options

      Under the merger agreement, at the effective time of the merger, each
option to purchase a share of the company's common stock outstanding and
unexercised as of the effective time of the merger granted pursuant to the
Hagler Bailly Employee Incentive and Non-Qualified Stock Option and Restricted
Stock Plan will be canceled, whether or not then exercisable or vested.


                                       33
<PAGE>

      With respect to options which are vested and have an exercise price of
less than $5.32, PA Consulting Group, Inc. will pay an amount per option equal
to the excess of $5.32 (as may be adjusted) over each option's per share
exercise price (the "option spread") to the holders of such options.

      With respect to options which have an exercise price equal to or greater
than $5.32 per share, PA Consulting Group, Inc. will pay an amount per option
grant equal to $1.00 (or a lesser amount if the total number of grants of
out-of-the-money options is greater 2,000) multiplied by the total number of
grants of out-of-the-money options to such optionholder. To the extent that the
number of grants of out-of-the-money options exceeds 2,000, the amount to be
received by each optionholder per grant will be reduced pro rata so that in the
aggregate the consideration paid to holders of out-of-the-money options does not
exceed $2,000.

      With respect to any option which is not, as of the effective time of the
merger, vested, but which has an exercise price of less than $5.32, PA
Consulting Group, Inc. will pay to the optionholder the option spread as soon as
practicable after the date when (but only if) such option would otherwise have
vested if such option had not been canceled.

Exchange of Shares for Cash

      Immediately prior to the effective time of the merger, PA Consulting
Group, Inc. will deposit with a paying agent designated by the company and PA
Consulting Group, Inc. an amount in cash equal to the product of the number of
shares outstanding immediately prior to the effective time of the merger and
$5.32 (subject to possible downward adjustment). Promptly after the effective
time of the merger (but in any event within one business day thereafter), the
paying agent will mail to each holder of record of common stock (other than
holders who have perfected dissenters' rights of appraisal) a letter of
transmittal and instructions on how to surrender their stock certificates in
exchange for the cash merger consideration.

      Please do not send in your stock certificates until you receive the letter
of transmittal and instructions from the paying agent. Do not return your stock
certificates with the enclosed proxy card.

      After receipt of the letter of transmittal, each holder of certificates
(other than holders who have perfected dissenters' rights of appraisal) that
represented common stock prior to the merger should surrender the certificates
together with the signed letter of transmittal duly executed, and any other
required documents as set forth in the letter of transmittal to the paying
agent, and each such holder will receive in exchange the merger consideration.
Thereafter, the stockholder will be entitled to receive an amount of cash equal
to the product of the number of shares of common stock formerly represented by
that stockholder's certificate(s) and $5.32 (subject to possible downward
adjustment).

      After the effective time of the merger, each certificate formerly
representing shares of common stock (other than those with respect to which
dissenters' rights of appraisal have been perfected), until surrendered and
exchanged, will be deemed for all purposes to evidence the right to receive only
the merger consideration, without interest, for the shares of common stock
represented.

      Other than transfers pursuant to Section 262 of the Delaware General
Corporation Law relating to dissenters' rights of appraisal, after the
completion of the merger, (i) there will be no further transfers of shares of
common stock, and (ii) stock certificates presented for transfer after the
completion of the merger will be canceled and exchanged for the merger
consideration.


                                       34
<PAGE>

      If a certificate for shares of common stock has been lost, stolen or
destroyed, payment will be made in accordance with the merger agreement upon
receipt by the paying agent of an affidavit setting forth that fact by the
person claiming such lost, stolen and destroyed certificate and granting a
reasonable indemnity against any claim that may be made against PA Consulting
Group, Inc., the company or the paying agent with respect to such certificate.

      o     notice of any event which would cause any of the representations or

            use of commercially reasonable efforts not to take any action or
            enter into any transaction which would be expected to cause the

Effect of the Earnout Agreement

      On August 12, 1999, the company entered into a Share Exchange Agreement by
and among the company, GKMG and the stockholders of GKMG. (See "Related
Agreements -- The Earnout Agreement"). As a condition to the consummation of the
merger, the company was required to amend certain of the terms and conditions of
the Share Exchange Agreement. If the Share Exchange Agreement had not been
amended as contemplated by the merger agreement, the per share consideration of
$5.32 could have been reduced.

      On July 3, 2000 the company entered into the First Amendment to Share
Exchange Agreement (the "earnout agreement") with the former stockholders of
GKMG, pursuant to which the company and the former stockholders of GKMG amended
the Share Exchange Agreement with respect to certain contingent payment
obligations of the company under the Share Exchange Agreement, as well as other
terms. In full satisfaction of the contingent payment obligations of the company
under the Share Exchange Agreement, the former stockholders of GKMG and the
company agreed that the former stockholders of GKMG will be paid an aggregate
cash amount equal to (i) a cash payment for the first year earnout payment in
accordance with the Share Exchange Agreement; (ii) $2,620,000 over the next two
years in lieu of the second year earnout payment; and (iii) 192,857 multiplied
by $5.32 (subject to possible downward adjustment, but in no event less than
$5.25) payable immediately prior to the closing of the merger agreement.
Additionally, the company agreed to waive any claims which the company might
have against the former stockholders of GKMG under the indemnification
provisions of the Share Exchange Agreement. The effectiveness of the earnout
agreement is conditioned on the closing of the merger agreement as more fully
described in the earnout agreement. PA Consulting Group, Inc. has approved the
terms of the earnout agreement and agreed that there will be no downward
adjustment to the $5.32 per share purchase price as a result of the earnout
agreement and/or the Share Exchange Agreement.

No Solicitation of Proposals

      Under the merger agreement, the company has agreed to, and shall cause any
of its subsidiaries and their respective affiliates, directors, officers,
financial and legal advisors and other representatives to, cease immediately all
activities, discussions, and negotiations, if any, with any person conducted
with respect to any acquisition proposal (as defined below).

      In addition, the company has agreed not to, and not to permit any of its
subsidiaries to, directly or indirectly, through any of their respective
affiliates, directors, officers, financial or legal advisors, or other
representatives:

      o     take any action to solicit, initiate, facilitate or encourage any
            acquisition proposal; or

      o     engage in negotiations or discussions with, or disclose any
            nonpublic information relating to the company or any of its
            subsidiaries or afford access to the properties, books or records of
            the company or any of its subsidiaries to any person making, or
            which the company or any such representative has reason to believe
            is likely to make, an acquisition proposal (or a potential
            acquisition proposal).

      However, prior to the adoption of the merger agreement by the company's
stockholders, the company, in response to an unsolicited acquisition proposal,
may:

      o     request clarifications from, or furnish information to, any third
            party which makes such an unsolicited acquisition proposal, for the
            purpose of obtaining information reasonably necessary to ascertain
            whether such acquisition proposal is, or should reasonably be
            expected to lead to, a superior proposal (as defined below); and


                                       40
<PAGE>

      o     if the board of directors (after consultation with an independent,
            nationally recognized investment bank) reasonably determines in good
            faith that such acquisition proposal is or is reasonably expected to
            be a superior proposal, participate in discussions or negotiations
            with or furnish information to the third party which has made such
            acquisition proposal.

      Prior to taking any action with respect to such unsolicited acquisition
proposal, the following conditions must be met:

      o     the company must enter into a confidentiality agreement with such
            third party with confidentiality and standstill terms at least as
            stringent as those contained in the confidentiality agreement
            between the company and PA Consulting Group, Inc. and, to the extent
            permitted by such confidentiality agreement to which the company
            becomes subject, the company has notified PA Consulting Group, Inc.
            in writing of the receipt of an acquisition proposal which notice
            will include a detailed summary of the acquisition proposal and
            copies of any documentation received by the company in connection
            with such acquisition proposal;

      o     the board of directors (after receiving advice from outside legal
            counsel) reasonably determines in good faith that it is necessary to
            take each such action in order to comply with its fiduciary duties
            under Delaware law; and

      o     the board of directors has concluded that such third party is
            capable of executing a definitive agreement and consummating a
            transaction on a reasonable schedule.

      Under the merger agreement, the term:

      o     "acquisition proposal" means any proposal or offer to acquire all or
            any substantial part of the business and properties or capital stock
            of the company or its subsidiaries, whether by merger,
            consolidation, sale of assets, tender offer or similar transaction
            or series of transactions involving the company or its subsidiaries;
            and

      o     "superior proposal" means a bona fide acquisition proposal that the
            board of directors determines in good faith (after consultation with
            its financial advisor and outside legal counsel) (i) would, if
            consummated, result in a transaction more favorable to stockholders,
            from a financial point of view, than the transactions contemplated
            by the merger agreement, taking into account all the terms and
            conditions of such acquisition proposal, including any proposed
            break-up fees or similar devices, expense reimbursement provisions,
            conditions to consummation and conditions to execution of a
            definitive agreement, and (ii) is reasonably capable of being
            consummated.

      Notwithstanding the terms of the no solicitation provision of the merger
agreement, the company and PA Consulting Group, Inc. have agreed that the
company may take any necessary actions to divest its Indonesian subsidiary,
Fieldston Publications, Inc. and CapGemini Hagler Bailly LLC, subject to PA
Consulting Group, Inc.'s reasonable satisfaction with the terms of any such
divestitures.

            or its subsidiaries operate or provide services, but only to the
            extent in the case of (A) or (B) that any such effect, change or
            development adversely affects the company in substantially the same
            manner and to substantially the same degree as similarly situated
            companies in the same industry;

      The merger agreement may be terminated at any time prior to the effective
time of the merger, whether before or after the requisite stockholder approval,
in the circumstances listed below.

      The merger agreement may be terminated by mutual written consent of the
company and PA Consulting Group, Inc.

      The merger agreement may be terminated by either the company or PA
Consulting Group, Inc., if any of the following events occur:

      o     the other materially breaches any of its representations,
            warranties, covenants or agreements contained in the merger
            agreement and causes the conditions to closing relating to those
            representations, warranties, covenants and agreements to be
            unsatisfied, and such breach has not been cured, or by its nature or
            timing cannot be cured, within 30 days after written notice thereof;

      o     there exists any final and nonappealable decree, permanent
            injunction, judgment, order or other action preventing or
            prohibiting consummation of the merger;

      o     the stockholders do not approve the merger and do not approve and
            adopt the merger agreement at the special meeting; or

      o     the merger is not consummated by the date which is 180 days after
            the date of the merger agreement, provided that the right to
            terminate the merger agreement is not available to any party whose
            breach of its obligations under the merger agreement has caused such
            termination and that applicable cure periods have run.

      PA Consulting Group, Inc. may terminate the merger agreement if:

      o     the company or its board of directors accepts or recommends to the
            stockholders a superior proposal;

      o     any of the stockholders who are parties to the voting agreement
            breach in any material respect any representation, warranty,
            covenant or agreement thereof and such breach has not been promptly
            cured after written notice to any such stockholder; provided that
            such breach shall be of the kind that denies PA Consulting Group,
            Inc. the material benefits contemplated by the voting agreement; or

      o     there has been a material adverse effect on the company which has
            not been cured within thirty days after notice thereof, provided
            that PA Consulting Group, Inc. shall be deemed to waive the right to
            terminate or not to close based on such material adverse effect if
            PA Consulting Group, Inc. has not exercised its right to terminate
            before the date which is sixty days after receipt or delivery of the
            notice that the material adverse effect has occurred.

      The company may terminate the merger agreement if:

      o     the company or its board of directors shall have accepted or
            recommended to the stockholders a superior proposal, provided that
            the company and its board of directors have materially complied with
            their obligations relating to negotiation with others under the
            merger agreement.

<PAGE>

      Under the merger agreement, the company is obligated to pay PA Consulting
Group, Inc. a termination fee of $5,000,000 if either the company or PA
Consulting Group, Inc. terminates the merger agreement as a result of the
company or its board of directors accepting or recommending to the stockholders
a superior proposal. The termination fee must be paid within 5 days of such
termination by wire transfer of immediately available funds.

Amendment, Extension and Waiver of the Merger Agreement

       The merger agreement may be amended in writing by the parties thereto by
action taken by or on behalf of their respective boards of directors at any time
prior to the effective time of the merger; provided that, after approval of the
merger agreement by the stockholders, no amendment may be made which would
reduce the amount of consideration beyond the amount of purchase price
adjustments provided for in the merger agreement or change the type of
consideration into which each share of common stock shall be converted pursuant
to the merger agreement upon consummation of the merger.

       At any time prior to the effective time of the merger, either the company
or PA Consulting Group, Inc. may, in writing, extend the other's time for the
performance of any of its obligations or other acts, waive any inaccuracies in
the other's representations and warranties contained in the merger agreement or
in any document delivered pursuant to the merger agreement and waive compliance
by the other with any of the agreements or conditions contained in the merger
agreement.

Indemnification and Insurance

      Under the merger agreement, PA Consulting Group, Inc. has agreed that it
will not, for a period of six years after the effective time of the merger,
amend the surviving corporation's certificate of incorporation or bylaws in any
manner that would adversely affect the rights of persons who at any time prior
to the effective time of the merger were identified as prospective indemnitees
in respect of actions or omissions occurring at or prior to the effective time
of the merger, unless such amendment is required by law.

      In addition, the merger agreement provides that the surviving corporation
will, after the effective time of the merger and to the extent permitted by
Delaware law, indemnify, defend and hold harmless the present and former
officers, directors and employees of the company and its subsidiaries against
all losses, expenses, claims, damages, liabilities or amounts that are paid in
settlement of, with the approval of PA Consulting Group, Inc. and the surviving
corporation, or otherwise in connection with, any claim, action, suit,
proceeding or investigation based in whole or in part on the fact that such
person is or was such a director, officer or employee and arising out of actions
or omissions occurring at or prior to the effective time of the merger. PA
Consulting Group, Inc. has also agreed to cause to be maintained in effect for
not less than six years after the effective time of the merger the current
policies of directors' and officers' liability insurance and fiduciary liability
insurance maintained by the company (or substitute policies with substantially
the same coverage and terms) with respect to matters occurring prior to the
effective time of the merger, except that PA Consulting Group, Inc. shall not be
required to pay an annual premium for such insurance of more than 200% of the
last annual premium paid prior to the date of the merger agreement.

Expenses of the Merger

      The company and PA Consulting Group, Inc. will each pay their own costs
and expenses relating to the merger agreement and the transactions contemplated
thereby. If the closing does not occur, the company will reimburse PA Consulting
Group, Inc. one-half of the filing fees paid by


                                       45

PA Consulting Group, Inc. in connection with filings made pursuant to U.S. and
foreign antitrust laws.

                                 RELATED AGREEMENTS

The Voting Agreement

      As an inducement for PA Consulting Group, Inc. to enter into the merger
agreement, certain of the directors, officers and affiliates of the company have
entered into a voting agreement with PA Consulting Group, Inc. and PA Holdings
Inc., pursuant to which they have agreed to vote all of their shares of common
stock: (i) in favor of the merger and the adoption of the merger and the
transactions contemplated thereby; (ii) against approval or adoption of
resolutions which would prevent or materially delay the company from performing
its obligations under the merger agreement; and (iii) against any action which
would constitute a material breach of any provision of the merger agreement.

      As of July 7, 2000, these directors, officers and affiliates owned in the
aggregate 2,170,849 shares of common stock, which represented approximately
12.1% of the outstanding company common stock. The voting agreement will
terminate upon the earlier of the termination of the merger agreement or the
effective time of the merger.

The Earnout Agreement

      On August 12, 1999, the company acquired all of the outstanding stock of
GKMG, Inc., a Washington, D.C.-based consulting firm specializing in the
economic, strategic, financial and regulatory analysis of the aviation industry,
in exchange for 1,420,000 shares of the company's common stock. Under the terms
of the Share Exchange Agreement by and among the company, GKMG and former
stockholders of GKMG, the company is obligated to issue additional shares of its
common stock to the former stockholders of GKMG with a fair market value (as
defined in the Share Exchange Agreement) up to $15 million if certain earnings
targets for GKMG are met for the periods July 1, 1999 to June 30, 2000 and July
1, 2000 to June 30, 2001. In addition, the company is obligated to issue up to
192,857 additional shares of its common stock to the former shareholders of GKMG
if certain stock price performance contingencies are not met.

      As a condition to the consummation of the merger, the company was required
to amend certain of the terms and conditions of the Share Exchange Agreement. If
the Share Exchange Agreement had not been amended as contemplated by the merger
agreement, the merger consideration of $5.32 per share could have been reduced.

      On July 3, 2000, the company entered into the earnout agreement with the
former stockholders of GKMG, pursuant to which the company and the former
stockholders of GKMG amended the Share Exchange Agreement with respect to
certain contingent payment obligations of the company under the Share Exchange
Agreement, as well as other terms. In full satisfaction of the contingent
payment obligations of the company under the Share Exchange Agreement, the
former stockholders of GKMG and the company agreed that the former stockholders
of GKMG will be paid an aggregate cash amount equal to (i) a cash payment for
the first year earnout payment in accordance with the Share Exchange Agreement;
(ii) $2,620,000 over the next two years in lieu of the second year earnout
payment; and (iii) 192,857 multiplied by $5.32 (subject to possible downward
adjustment, but in no event less than $5.25) payable immediately prior to the
closing of the merger agreement. Additionally, the company agreed to waive any
claims which the company might have against the former stockholders of GKMG
under the indemnification provisions of the Share Exchange Agreement. The
effectiveness of the earnout agreement is conditioned on the closing of the
merger agreement as is more fully described in the earnout agreement. PA
Consulting Group, Inc. has approved the terms of the earnout agreement and
agreed that there will be no downward adjustment to the $5.32 per share purchase
price as a result of the earnout agreement and/or the Share Exchange Agreement.

                          AGREEMENT AND PLAN OF MERGER

            THIS AGREEMENT AND PLAN OF MERGER (this "Agreement") is entered into
as of the 19th day of June, 2000, by and among Hagler Bailly, Inc., a Delaware
corporation (the "Company"), PA Consulting Group, Inc., a New Jersey corporation
("Acquiror"), PA Holdings Inc., a Delaware corporation ("Merger Sub") and PA
Holdings Limited, a corporation organized under the laws of England and Wales
and the ultimate parent entity of the Acquiror (the "Parent"), only with respect
to the payment obligations contained in Section 2.2, the representations
contained in Sections 5.5 and 5.8, and the provisions of Article X hereof.

            WHEREAS, the Board of Directors of the Company has determined that
it is fair to, and in the best interest of its stockholders that Merger Sub, a
wholly-owned subsidiary of Acquiror, merge with and into the Company, pursuant
to and subject to the terms and conditions of this Agreement and the Delaware
General Corporation Law ("Delaware Law");

            WHEREAS, concurrently with the execution of this Agreement and as an
inducement to Acquiror to enter into this Agreement, certain of the officers,
directors and affiliates of the Company ("Company Affiliates"), have entered or
will enter into a voting agreement with Acquiror (the "Voting Agreement")
pursuant to which, among other things, each Company Affiliate has agreed to vote
all of its shares of common stock of the Company in favor of this Agreement, the
Merger (as defined below) and the other transactions contemplated by this
Agreement;

            WHEREAS, the Company is negotiating to enter into an agreement (the
"Earnout Agreement") with respect to the future payment by the Company of its
obligations under existing earn-out and price performance share arrangements
with the former shareholders of GKMG, Inc., a draft of which is attached hereto
as Schedule A.

      NOW, THEREFORE, in consideration of the foregoing and the respective
representations, warranties, covenants and agreements set forth in this
Agreement, the parties hereto agree as follows:

Agreement, and in accordance with Delaware Law, at the Effective Time (as

corporation of the Merger (sometimes referred to herein as the "Surviving
Corporation") and a wholly-owned subsidiary of Acquiror. The name of the
Surviving Corporation shall be PA/Hagler Bailly Inc.

<PAGE>

      SECTION 1.2 Effective Time.

            As promptly as practicable after the Closing, the parties hereto
shall cause the Merger to be consummated by filing a certificate of merger (the

      SECTION 1.3 Effect of the Merger.

            At the Effective Time, the effect of the Merger shall be as provided
in the applicable provisions of Delaware Law. At the Effective Time, except as
otherwise provided herein, all the rights, privileges, powers and franchises of
Merger Sub and the Company, shall vest in the Surviving Corporation, and all
debts, liabilities and duties of Merger Sub and the Company shall become the
debts, liabilities and duties of the Surviving Corporation.

      SECTION 1.4 Certificate of Incorporation; Bylaws.

            At the Effective Time, (a) the certificate of incorporation of the

Corporation.

      SECTION 1.5 Directors and Officers.

Effective Time shall be the initial directors and officers of the Surviving
Corporation, in each case until their respective successors are duly elected or
appointed and qualified.

      SECTION 1.6 Closing.

            Subject to the terms and conditions of this Agreement, the closing

agreed to in writing by the parties hereto.

      SECTION 1.7 Subsequent Actions.

            If, at any time after the Effective Time, the Surviving Corporation
shall consider or be advised that any deeds, bills of sale, assignments,
assurances or any other actions or things are necessary or desirable to continue
in, vest, perfect or confirm of record or otherwise in the Surviving Corporation
its right, title or interest in, to or under any of the rights, properties,
privileges, franchises or assets of either of its constituent corporations
acquired or to be acquired by the Surviving Corporation as a result of, or in
connection with, the Merger or otherwise to carry out this Agreement, the
officers and directors of the Surviving Corporation shall be


                                       A-2
<PAGE>

directed and authorized to execute and deliver, in the name and on behalf of
either of such constituent corporations, all such deeds, bills of sale,
assignments and assurances and to take and do, in the name and on behalf of each
of such corporations or otherwise, all such other actions and things as may be
necessary or desirable to vest, perfect or confirm any and all right, title and

                                   ARTICLE II.

               CONVERSION OF SECURITIES; EXCHANGE OF CERTIFICATES

      SECTION 2.1 Conversion of Securities.

            At the Effective Time, by virtue of the Merger and without any
action on the part of Acquiror, Merger Sub, the Company or the holders of any of
the following securities:

            (a) Company Common Stock. Subject to the other provisions of this
Section 2.1, each share of common stock, par value $.01 per share, of the
Company (the "Common Stock") issued and outstanding immediately prior to the
Effective Time (excluding any shares described in Sections 2.1(b) and (c) and
any Dissenting Shares (as hereinafter defined)), shall be converted into the
right to receive $5.32 in cash, without interest (the "Per Share Amount");
provided, however, that the Per Share Amount shall be adjusted in accordance
with Section 2.1(e) below if and only if (i) the number of shares of Common
Stock issued and outstanding immediately prior to the Effective Time shall be
greater than the sum of (A) 17,927,812 plus (B) the number of shares of Common
Stock issued upon any exercise of the Options set forth on Schedule 2.1 hereto
prior to the Effective Time plus (C) any other Options that have an exercise
price of $5.32 or higher which are exercised prior to the Effective Time; and/or
(ii) Schedule 2.1 does not set forth all of the Options outstanding immediately
prior to the Effective Time which have an exercise price which is less than
$5.32; and/or (iii) any further shares of Common Stock are issued by the Company
pursuant to the Share Exchange Agreement dated August 12, 1999 relating to GKMG,
Inc.; and/or (iv) if the aggregate economic value of the consideration and other
terms to be paid or assumed by the Company pursuant to the Earn-Out Agreement
exceeds the amount contemplated in the draft Earn-Out Agreement attached hereto
as Schedule A. All such shares of Common Stock shall cease to be outstanding and
shall automatically be canceled and retired and shall cease to exist, and each
certificate previously evidencing any such shares shall thereafter represent
only the right to receive the Merger Consideration as described below. The
holders of certificates previously evidencing such shares of Common Stock
outstanding immediately prior to the Effective Time shall cease to have any
rights with respect to such shares of Common Stock, except as otherwise provided
herein or by law. Each such certificate previously evidencing such shares of
Common Stock shall be exchanged for the Per Share Amount multiplied by the
number of shares previously evidenced by the canceled certificate upon the
surrender of such certificate in accordance with the provisions of Section 2.2,
without interest;

            (b) Acquiror-Owned Shares. All shares of capital stock of the
Company owned, directly or indirectly, by Acquiror, Merger Sub or any Subsidiary
of Acquiror immediately prior


                                       A-3
<PAGE>

to the Effective Time shall be canceled and extinguished without any conversion
thereof and no cash or other consideration shall be delivered or deliverable in
exchange therefor;

            (c) Treasury Stock. All shares of capital stock of the Company held
in the treasury of the Company immediately prior to the Effective Time shall be
canceled and extinguished without any conversion thereof and no cash or other
consideration shall be delivered or deliverable in exchange therefor; and

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

            (e) Purchase Price Adjustment. If the Unadjusted Aggregate Purchase
Price would have exceeded $95,708,973.83 as calculated at the Effective Time
prior to any adjustments as contemplated by this Section 2.1(e), then the Per
Share Amount shall be reduced as follows: (a) if the Unadjusted Aggregate
Purchase Price is greater than $95,708,973.83 but is less than or equal to
$95,890,877.83, then the Per Share Amount shall be reduced to $5.31, (b) if the
Unadjusted Aggregate Purchase Price is greater than $95,890,877.83 but is less
than or equal to $96,072,781.83, then the Per Share Amount shall be reduced to
$5.30, and (c) if the Unadjusted Aggregate Purchase Price is greater than
$96,072,781.83, then for each $181,528 increment above such amount, the Per
Share Amount shall be reduced by $.01.

      For purposes of this Section 2.1(e), the "Unadjusted Aggregate Purchase
Price" shall mean initially the amount equal to (a) the number of shares of
Common Stock outstanding immediately prior to the Effective Time multiplied by a
Per Share Amount of $5.32, plus (b) the aggregate value of the Option Spread
calculated based on a Per Share Amount of $5.32, plus (c) One Thousand Five
Hundred Two Dollars ($1,502), plus (d) the amount by which the aggregate
economic value of the consideration or other terms to be paid or assumed by the
Company pursuant to the final form of the Earn-Out Agreement exceeds the
aggregate economic value of the consideration or other terms contemplated in the
draft of the Earn-Out Agreement attached as Schedule A, minus (e) all amounts
received by the Company after the date hereof in connection with the exercise of
Options prior to the Closing Date.

      The provisions of this Section 2.1(e) shall only be operative as set forth
in Section 2.1(a).

      SECTION 2.2 Payment.

            (a) Paying Agent. Immediately prior to the Effective Time, Acquiror
shall, on behalf of Merger Sub, deposit with a bank theretofore designated by
the Company and Acquiror (the "Paying Agent"), for the benefit of the holders of
shares of Common Stock (excluding any shares described in Sections 2.1(b) and
(c) and any Dissenting Shares), for payment in accordance with this Article II,
through the Paying Agent, cash in an aggregate amount equal to the Per Share
Amount multiplied by the number of shares of Common Stock outstanding
immediately prior to the Effective Time (excluding any shares described in
Sections 2.1(b) and (c) and any Dissenting Shares) (such cash being hereinafter
referred to as the "Payment Fund"). Acquiror shall cause the Paying Agent,
pursuant to irrevocable instructions, to deliver


                                       A-4
<PAGE>

the cash contemplated to be paid pursuant to Section 2.1(a) out of the Payment
Fund. The Payment Fund shall not be used for any other purpose.

            (b) Payment Procedures. Promptly after the Effective Time, but in no
event later than one (1) business day thereafter, Acquiror shall cause the
Paying Agent to mail to each record holder, as of the Effective Time, of an
outstanding certificate (each a "Certificate" and collectively, the
"Certificates") that immediately prior to the Effective Time evidenced
outstanding shares of Common Stock (excluding any shares described in Section
2.1(b) and Section 2.1 (c) and any Dissenting Shares), a form letter of
transmittal and instructions for use in effecting the surrender of the
Certificates for payment therefor. Upon surrender to the Paying Agent of a
Certificate, together with such letter of transmittal duly executed, and any
other required documents, the holder of such Certificate shall be entitled to
receive in exchange therefor the consideration set forth in Section 2.1(a) (the
"Merger Consideration"), and such Certificate shall forthwith be canceled. No
interest will be paid or accrued on the cash payable upon the surrender of the
Certificates. Until surrendered in accordance with the provisions of this
Section 2.2, each Certificate shall represent for all purposes only the right to
receive the consideration set forth in Section 2.1(a), without any interest
thereon.

            (c) No Further Rights in Common Stock. All cash paid upon conversion
of the shares of Common Stock in accordance with the terms of this Article II,
and all cash paid pursuant to Section 2.5, shall be deemed to have been paid in
full satisfaction of all rights pertaining to such shares of Common Stock.

            (d) Termination of Payment Fund. Any portion of the Payment Fund
that remains undistributed to the holders of Common Stock for one hundred eighty
(180) days after the Effective Time shall be delivered to Acquiror, upon demand,
and any holders of Common Stock that have not theretofore complied with this
Article II shall thereafter look only to the Surviving Corporation and Acquiror
for the Merger Consideration to which they are entitled.

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

            (f) Lost, Stolen or Destroyed Certificates. In the event any
Certificate evidencing shares of Common Stock shall have been lost, stolen or
destroyed, upon the making of an affidavit setting forth that fact by the person
claiming such lost, stolen or destroyed Certificate(s) and granting a reasonable
indemnity against any claim that may be made against Acquiror or the Paying
Agent with respect to such Certificate(s), Acquiror shall cause the Paying Agent
to pay to such person the Merger Consideration with respect to such lost, stolen
or destroyed Certificate(s).

      SECTION 2.3 Company Options; Restricted Stock.

            (a) Options. At the Effective Time, each option to purchase a share
of the Company Stock (an "Option" and, collectively, the "Options") outstanding
and unexercised as of the Closing Date granted pursuant to the Company Stock
Option Plan shall be canceled, whether or not then exercisable or vested, and
shall represent the right to receive the following


                                       A-5
<PAGE>

consideration in settlement thereof. As soon as practicable after the Effective
Time, the Acquiror shall, on behalf of Merger Sub, pay to the optionholder
thereof the greater of (i) the excess, if any, of the Per Share Amount (as may
be adjusted pursuant to Section 2.1(e)) over such Option's per share exercise
price (the "Option Spread") multiplied by the number of Options which remain
unexercised at the Effective Time in relation to those Options set forth in
Schedule 2.1 or (ii) One Dollar ($1.00) multiplied by the total number of grants
(as opposed to the number of shares of Common Stock underlying a particular
grant) of Options to such optionholder; provided, that the number of such grants
shall not exceed 2,000. To the extent that the number of grants exceeds 2,000,
then the amount to be received by each optionholder per grant shall be reduced
pro rata so that in the aggregate the consideration per grant multiplied by the
number of grants does not exceed $2,000. With respect to any Option which is
not, as of the Effective Term, vested, the Acquiror shall, on behalf of Merger
Sub, pay to the optionholder thereof the Option Spread, as soon as practicable
after the date when (but only if) such Option would otherwise have vested had
such Option not been canceled pursuant hereto.

            (b) The Company has no outstanding shares of restricted stock.

            (c) Notice. As soon as practicable after the Effective Time,
Acquiror shall deliver to each holder of an Option an appropriate written notice
setting forth such holder's rights pursuant thereto.

      SECTION 2.4 Stock Transfer Books.

            At the Effective Time, the stock transfer books of the Company with
respect to all shares of capital stock of the Company shall be closed and no
further registration or transfers of such shares of capital stock shall
thereafter be made on the records of the Company. On or after the Effective
Time, any Certificates for shares of Common Stock (excluding any shares
described in Sections 2.1(b) and (c) and Dissenting Shares) presented to the
Paying Agent, the Surviving Corporation or Acquiror for any reason shall be
converted into the Merger Consideration.

      SECTION 2.5 Dissenting Shares.

            Notwithstanding any other provisions of this Agreement to the
contrary, shares of Common Stock that are issued and outstanding immediately
prior to the Effective Time and that are held by stockholders who shall not have
voted in favor of the Merger or consented thereto in writing and who shall have
demanded properly in writing appraisal for such shares in accordance with
Section 262 of Delaware Law (collectively, the "Dissenting Shares") shall not be
converted into or represent the right to receive the Merger Consideration. Such
stockholders shall be entitled to receive payment of the appraised value of such
shares of Common Stock held by them in accordance with the provisions of such
Section 262, except that all Dissenting Shares held by stockholders who shall
have failed to perfect or who effectively shall have withdrawn or lost their
rights to appraisal of such shares of Common Stock under such Section 262 shall
thereupon be deemed to have been converted into and to have become exchangeable,
as of the Effective Time, for the right to receive, without any interest
thereon, the Merger Consideration, upon surrender, in the manner provided in
Section 2.2, of the certificate or certificates that formerly evidenced such
shares of Common Stock.

            The Company hereby represents and warrants to Acquiror and Merger
Sub as follows:

      SECTION 3.1 Organization and Qualification; Company Subsidiaries.

            (a) Each of the Company and the Subsidiaries (as defined below) of
the Company (each a "Company Subsidiary" and collectively, the "Company
Subsidiaries") is a corporation or limited liability company duly organized,
validly existing and in good standing under the laws of the jurisdiction of its
organization. Each of the Company and the Company Subsidiaries is duly qualified
to conduct its business, and is in good standing, in each jurisdiction where the
character of its properties owned, operated or leased or the nature of its
activities makes such qualification necessary, except for such jurisdictions
where failure to be so qualified and in good standing, individually or in the
aggregate, would not reasonably be expected to have a Company Material Adverse
Effect (as defined below). The minute books of the Company accurately reflect in
all material respects all material corporate actions taken by their stockholders
and boards of directors (including committees of their boards of directors).
Each of the Company and the Company Subsidiaries has the requisite power and
authority and any necessary governmental authority, franchise, license or permit
to own, operate, lease and otherwise to hold and operate its assets and
properties and to carry on the businesses as now being conducted, except for
such failure which, individually or in the aggregate, is not reasonably expected
to have a Company Material Adverse Effect. The Company has no Company
Subsidiaries (as defined below) or any equity or similar interest in any entity
other than those listed in Schedule 3.1.

      SECTION 3.2 Certificate of Incorporation and Bylaws.

            The Company has heretofore made available to Acquiror a complete and
correct copy of the certificate or articles of incorporation and the bylaws of
the Company, (ii) a complete and correct copy of the certificate or articles of
incorporation and the bylaws of each Company Subsidiary that is a corporation,
and a correct copy of the limited liability company agreement for each Company
Subsidiary that is a limited liability company, and (iii) a complete and correct
copy of the certificate or articles of incorporation and the bylaws, limited
liability company agreement or partnership agreement, as the case may be, of
each entity in which the Company or a Company Subsidiary has an equity or
equity-related investment (individually a "Company Investee Entity" and
collectively "Company Investee Entities"). Each such certificate or articles of
incorporation, bylaws, limited liability company agreement and partnership
agreement is in full force and effect. Neither the Company, any Company
Subsidiary or Company Investee Entity is in violation of any of the provisions
of each such certificate or articles of incorporation, bylaws, limited liability
company agreement, partnership agreement or other organizational document.

      SECTION 3.3 Capitalization.


                                       A-7
<PAGE>

            The authorized capital stock of the Company consists of: (a) fifty
million (50,000,000) shares of Common Stock, of which seventeen million nine
hundred twenty-seven thousand eight hundred twelve (17,927,812) shares are
issued and outstanding as of the date of this Agreement; and (b) five million
(5,000,000) shares of preferred stock, par value $.01 per share, of which no
shares are issued and outstanding. The Board has amended the Company Stock
Option Plan to increase the number to eight million (8,000,000) but the
amendment will only become effective when the Stockholders of the Company
approve this amendment; provided, however, that in the event that the Merger
shall take place, nothing in this Section 3.3 shall be construed to permit the
issuance of a greater number of shares than 17,927,812 shares of Common Stock
plus the number of shares of Common Stock issuable upon any exercise of the
Options set forth either on Schedule 2.1 hereto plus any shares of Common Stock
issuable upon any exercise of other Options that have an exercise price in
excess of the Per Share Amount. Eight million (8,000,000) shares of Common Stock
have been reserved for issuance upon the exercise of Options granted under the
Company Stock Option Plan, of which 2,859,293 shares are issuable upon the
exercise of Options outstanding under the Company Stock Option Plan as of the
date hereof. Except as set forth in Schedule 3.3 and other than as set forth on
Schedule 2.1 and Options issued under the Company Stock Option Plan with
exercise prices above the Per Share Amount, there are no options, warrants or
other rights, agreements, arrangements or commitments of any character relating
to the issued or unissued capital stock of the Company or any Company Subsidiary
or obligating the Company or any Company Subsidiary to issue or sell any shares
of capital stock of, or other equity interests in the Company or any Company
Subsidiary. Except as set forth in Schedule 3.3 and other than as set forth on
Schedule 2.1 and Options issued under the Company Stock Option Plan with
exercise prices above the Per Share Amount, there are no outstanding contractual
obligations of the Company to repurchase, redeem or otherwise acquire any shares
of its capital stock or make any material investment (in the form of a loan,
capital contribution or otherwise) in any other person. All of the issued and
outstanding shares of Common Stock have been duly authorized and validly issued
and are fully paid and nonassessable and not subject to preemptive rights. With
respect to each Company Subsidiary that is a corporation, all of the outstanding
shares of capital stock of such Company Subsidiary have been duly authorized and
validly issued and are fully paid and nonassessable. With respect to each
Company Subsidiary that is a corporation, all of the outstanding shares of
capital stock owned by the Company, and with respect to each Company Subsidiary
that is a limited liability company, all of the limited liability company
interests owned by the Company, are owned by the Company free and clear of any
liens, security interests, pledges, agreements, claims, charges or encumbrances
(the "Encumbrances"). As of the date hereof, the only outstanding indebtedness
for borrowed money for which the Company or any of the Company Subsidiaries is
liable (including contingent liability) is as set forth in Schedule 3.3.

      SECTION 3.4 Authority.

            Subject to the approval of this Agreement by the holders of a
majority of the outstanding shares of Common Stock, the Company has the
necessary corporate power and authority to enter into, perform its obligations
under and engage in any transactions contemplated by this Agreement and to
consummate the Merger. The execution and delivery of this Agreement by the
Company and the consummation by the Company of the transactions contemplated
hereby have been duly and validly authorized by all necessary corporate action
and no other corporate proceedings on the part of the Company are necessary to
authorize this


                                       A-8
<PAGE>

Agreement or to consummate the transactions contemplated hereby, other than,
with respect to consummation of the Merger, the foregoing approval of this
Agreement by the stockholders of the Company in accordance with Delaware Law.
This Agreement has been duly executed and delivered by the Company and, assuming
the due authorization, execution and delivery by Acquiror and Merger Sub,
constitutes a legal, valid and binding obligation of the Company, enforceable in
accordance with its terms, except as such enforceability may be limited by
bankruptcy, insolvency, reorganization, moratorium and other similar laws of
general applicability relating to or affecting creditors' rights generally and
by the application of general principles of equity.

      SECTION 3.5 No Conflict; Required Filings and Consents.

            (a) The execution and delivery of this Agreement by the Company do
not, and the performance by the Company of its obligations under this Agreement
will not, (i) conflict with or violate the certificate or articles of
incorporation, bylaws, limited liability company agreement, partnership
agreement or other organizational document of the Company, any Company
Subsidiary or any Company Investee Entity, (ii) subject to compliance with the
requirements set forth in Section 3.5(b) below, conflict with or violate any
law, statute, ordinance, rule, regulation, order, judgment or decree applicable
to the Company, any Company Subsidiary or any Company Investee Entity or by
which any of their respective properties is bound or affected, (iii) result in
any breach of or constitute a default (or an event which with notice or lapse of
time or both would become a default) under, or give to others any rights of
termination, amendment, acceleration or cancellation of, or result in the
creation of an Encumbrance on any of the properties or assets of the Company,
any Company Subsidiary or any Company Investee Entity pursuant to, any note,
bond, mortgage, indenture, contract, agreement, lease, license, permit,
franchise or other instrument or obligation to which the Company, any Company
Subsidiary or any Company Investee Entity is a party or by which the Company,
any Company Subsidiary, any Company Investee Entity or any of their respective
properties or assets is bound or affected, except, in the case of clauses (ii)
and (iii) above, for any such conflicts, violations, breaches, defaults or other
alterations or occurrences which, individually or in the aggregate, are not
reasonably expected to have a Company Material Adverse Effect.

            (b) The execution and delivery of this Agreement by the Company does
not, and the performance of this Agreement by the Company will not, require any
consent, approval, authorization or permit of, or filing with or notification
to, any government or any agency, bureau, board, commission, court, department,
political subdivision or other instrumentality of the U.S. Government or any of
the fifty states (each a "Governmental Entity"), except (i) for (A) applicable
requirements, if any, of the Securities Exchange Act of 1934 (the "Exchange
Act"), any exchange on which the Company's securities are traded, the

foreign antitrust or competition law or regulation, (B) applicable requirements,
if any, of the consents, approvals, authorizations or permits described in
Schedule 3.5, and (C) filing and recordation of appropriate merger documents as
required by Delaware Law and (ii) where failure to obtain such consents,
approvals, authorizations or permits, or to make such filings or notifications,
individually or in the aggregate, would not have a Company Material Adverse
Effect.

Subsidiary); (xi) all deferred compensation arrangements; and (xii) all swaps,
options, collars and any other hedging or derivative transactions. To the best
of the Company's knowledge, there are no agreements (except for restrictions

competing in any line of business.

            (b) Except as set forth in Schedule 3.12, all the Material Contracts
are valid and in full force and effect on the date hereof except to the extent
they have previously expired in accordance with their terms, and neither the
Company nor any Company Subsidiary has (or has any knowledge that any other
party thereto has) violated any provision of, or committed or failed to perform
any act which with or without notice, lapse of time or both would constitute a
default under the provisions of, any Material Contract, except for defaults

Company Material Adverse Effect. True and complete copies of all Material
Contracts have been delivered to Acquiror or made available for inspection.

      SECTION 3.13 Employee Benefit Plans.

            Except as set forth in Schedule 3.13,

            (a) All material benefit and compensation plans, contracts, policies
or arrangements covering current or former employees of the Company and its
Company Subsidiaries (the "Employees") and current or former directors of the
Company, including, but not limited to, "employee benefit plans" within the
meaning of Section 3(3) of the Employee Retirement Income Security Act of 1974,
as amended ("ERISA"), and deferred compensation, stock option, stock purchase,
stock appreciation rights, stock based, incentive and bonus plans (the "Benefit
Plans"), are listed in Schedule 3.13. True and complete copies of all Benefit
Plans, including, but not limited to, any trust instruments and insurance
contracts forming a part of any Benefit Plans, and all amendments thereto have
been provided or made available to Acquiror.

            (b) All employee benefit plans covering Employees (the "Plans") are
in substantial compliance with all applicable legal requirements. Each Plan
which is an "employee pension benefit plan" within the meaning of Section 3(2)
of ERISA ("Pension Plan") and which is intended to be qualified under Section
401(a) of the Code, has received a favorable determination letter from the
Internal Revenue Service with respect to "TRA" (as defined in Section 1 of Rev.
Proc. 93-39), and the Company is not aware of any circumstances likely to result
in revocation of any such favorable determination letter. There is no material
pending or, to the knowledge of the Company threatened, litigation relating to
the Plans. Neither the Company nor any Company Subsidiaries has engaged in a
transaction with respect to any Plan that, assuming the taxable period of such
transaction expired as of the date hereof, could subject the Company or any
subsidiary to a tax or penalty imposed by either Section 4975 of the Code or
Section 502(i) of ERISA in an amount which would be material.

            (c) No liability under Title IV of ERISA has been or is expected to
be incurred by the Company or any Company Subsidiaries with respect to any
ongoing, frozen or terminated "single-employer plan", within the meaning of
Section 4001(a)(15) of ERISA, currently or formerly maintained by any of them,
or the single-employer plan of any entity which is


                                      A-15

considered one employer with the Company under Section 4001 of ERISA or Section
414 of the Code (an "ERISA Affiliate"). Neither the Company, any Company
Subsidiaries nor an ERISA Affiliate has contributed to a "multiemployer plan",
within the meaning of Section 3(37) of ERISA, at any time on or after September
26, 1980. No notice of a "reportable event", within the meaning of Section 4043
of ERISA for which the 30-day reporting requirement has not been waived, has
been required to be filed for any Pension Plan or by any ERISA Affiliate within
the 12-month period ending on the date hereof or will be required to be filed in
connection with the transactions contemplated by this Agreement. All
contributions required to be made under the terms of any Benefit Plan have been
timely made or have been reflected on the financial statements contained in the
Company SEC Reports. Neither any Pension Plan nor any single-employer plan of
an ERISA Affiliate has an "accumulated funding deficiency" (whether or not
waived) within the meaning of Section 412 of the Code or Section 302 of ERISA
and no ERISA Affiliate has an outstanding funding waiver. Neither the Company
nor any Company Subsidiaries has provided, or is required to provide, security
to any Pension Plan or to any single-employer plan of an ERISA Affiliate
pursuant to Section 401(a)(29) of the Code.

            (d) Under each Pension Plan which is a single-employer plan, as of
the last day of the most recent plan year ended prior to the date hereof, the
actuarially determined present value of all "benefit liabilities", within the
meaning of Section 4001(a)(16) of ERISA (as determined on the basis of the
actuarial assumptions contained in the Plan's most recent actuarial valuation),
did not exceed the then current value of the assets of such Plan, there has been
no material change in the financial condition of such Plan since the last day of
the most recent plan year and the assets of each such Plan are sufficient to
satisfy all Plan liabilities on a termination basis.

            (e) Other than under Section 4980B of the Code, the Federal Social
Security Act, or a plan qualified under Section 401 of the Code, neither the
Company nor any of Company Subsidiaries has any obligations for retiree health
and life benefits under any Benefit Plan, except as set forth on Schedule 3.13.
The Company or the Company Subsidiaries may amend or terminate any such Benefit
Plan at any time without incurring any material liability thereunder.

            (f) Except as set forth on Schedule 3.13 the consummation of the
transactions contemplated by this Agreement will not (i) entitle any employees
of the Company or any of the Company Subsidiaries to severance pay, (ii)
accelerate the time of payment or vesting or trigger any payment or funding
(through a grantor trust or otherwise) of compensation or benefits under,
increase the amount payable or trigger any other material obligation pursuant

Benefit Plans which would not be deductible under Section 162(m) or Section 280G
of the Code.

                              ADDITIONAL AGREEMENTS

      SECTION 7.1 Access and Information.

            (a) From the date hereof to the Effective Time, the Company shall,
and shall cause the Company Subsidiaries to, afford to Acquiror and its
officers, employees, accountants, consultants, legal counsel, representatives of
current and prospective sources of financing for the Merger and other
representatives of Acquiror (collectively, the "Acquiror Representatives"),
reasonable access during normal business hours to the properties, executive
personnel and all information concerning the business, properties, contracts,
records and personnel of the Company and the Company Subsidiaries as Acquiror
may reasonably request.

            (b) Any formal general communication with the Company's employees or
any communication of determination of future employment with any of the
Company's administrative employees, or any pre-merger activities which would
have a direct material impact on the financial condition of the Company shall be
subject to the prior approval of the Chief Executive Officer of the Company,
which approval shall not be unreasonably withheld, delayed or conditioned;
provided, however, that nothing contained in this Section 7.1(b) shall be
construed to prevent reasonable planning of the post-Closing integration or to
delay the Closing.

      SECTION 7.2 Confidentiality.

            Acquiror acknowledges and agrees that all information received from
or on behalf of the Company or any of the Company Subsidiaries in connection
with the Merger shall be deemed received pursuant to the confidentiality
agreement, dated as of December 9, 1999, between the Company and Acquiror (the
"Confidentiality Agreement") and Acquiror shall, and shall cause the Acquiror
Representatives to comply with the provisions of the Confidentiality Agreement
with respect to such information and the provisions of the Confidentiality
Agreement are hereby incorporated herein by reference with the same effect as if
fully set forth herein.

      SECTION 7.3 Stockholder Approval.

            The Company shall, promptly after the date of this Agreement, take
all action necessary in accordance with Delaware Law and its certificate of
incorporation and bylaws to convene, as promptly as possible, a meeting of the
Company's stockholders (the "Stockholders' Meeting") to approve and adopt this
Agreement and the Merger (and to take any and all other action that may be
necessary in order to effect consummation of the transactions contemplated
hereby); provided, however, that the Board of Directors of the Company shall
submit this Agreement to the Company's stockholders, whether or not the Board of
Directors of the Company at any time subsequent to the date hereof determines
that this Agreement is no longer advisable or recommends that the Stockholders
of the Company reject it. Unless the Board of Directors of the Company has
withdrawn its recommendation of this Agreement in compliance


                                      A-27
<PAGE>

herewith, the Company shall use its reasonable efforts to solicit from
stockholders of the Company proxies in favor of the approval and adoption of
this Agreement and the Merger.

      SECTION 7.4 Proxy Statement.

            (a) As promptly as practicable, the Company shall prepare and file
with the SEC a proxy statement in connection with the matters to be considered
at the Stockholders' Meeting (such proxy statement, together with any
supplements or amendments thereto, the "Proxy Statement"). The Company shall use
its reasonable efforts to cause the Proxy Statement to be cleared by the SEC for
mailing to the stockholders of the Company as promptly as practicable and shall
mail the Proxy Statement to its stockholders as promptly as practicable
thereafter. Acquiror shall furnish all information concerning it and the holders
of its capital stock as the Company may reasonably request in connection with
such actions. Unless the Board of Directors of the Company has withdrawn its
recommendation of this Agreement in compliance herewith, the Proxy Statement
shall include the recommendation of the Company's Board of Directors in favor of
approval of this Agreement (and any other necessary matters). Acquiror shall
have the right to review and comment on the Proxy Statement from time to time
before it is mailed to shareholders. The Company shall deliver drafts of the
Proxy Statement, any comments from the SEC on the Proxy Statement, draft
responses by the Company to any SEC comments, and other similar information and
documents related to the Proxy Statement and the related meeting of the Company
stockholders to the Acquiror in a timely manner sufficient so that Acquiror
shall have the opportunity to effectively comment thereon; provided, however,
that the contents of the Proxy Statement shall be prepared in the sole and
absolute discretion of the Company.

            (b) The information supplied by Acquiror for inclusion in the Proxy
Statement shall not, at the date the Proxy Statement (or any supplement thereto)
is first mailed by stockholders or at the time of the Stockholders' Meeting,
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they are made, not
misleading. If at any time prior to the Stockholders' Meeting any event or
circumstance relating to Acquiror or any of its affiliates, or its or their
respective officers or directors, should be discovered by Acquiror that should
be set forth in a supplement to the Proxy Statement, Acquiror shall promptly
inform the Company.

            (c) All information contained in the Proxy Statement (other than
information provided by Acquiror in writing for inclusion therein) shall not, at
the date the Proxy Statement (or any supplement thereto) is first mailed to
stockholders or at the time of the Stockholders' Meeting, contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary in order to make the statements therein, in light of
the circumstances under which they are made, not misleading. If at any time
prior to the Stockholders' Meeting any event or circumstance relating to the
Company or any of the Company Subsidiaries, or to its or their respective
officers or directors, should be discovered by the Company that should be set
forth in a supplement to the Proxy Statement, the Company shall promptly inform
Acquiror, continue to keep the Acquiror informed on a current basis of any
developments thereafter and mail such supplement to its shareholders within five
(5) business days of the occurrence of any such event or circumstance. All
documents that the Company is


                                      A-28
<PAGE>

responsible for filing with the SEC in connection with the transactions
contemplated herein, including the Proxy Statement, will comply as to form and
substance in all material respects with the applicable requirements of the
Exchange Act and the rules and regulations thereunder.

      SECTION 7.5 Further Action; Reasonable Efforts.

            (a) Each of the parties shall use commercially reasonable efforts to
take, or cause to be taken, all appropriate action, and do, or cause to be done,
all things necessary, proper or advisable under applicable laws or otherwise to
consummate and make effective the transactions contemplated by this Agreement as
promptly as practicable. This shall include commercially reasonable efforts to
(i) obtain all licenses, Permits, consents, approvals, authorizations,
qualifications and orders of Governmental Entities and parties to contracts with
the Company and Acquiror as are necessary for the transactions contemplated
herein, and (ii) retain SVPs, VPs and other Consulting Staff and to encourage
such persons to enter into employment agreements with Acquiror on substantially
the terms offered by Acquiror in writing to such persons prior to the date
hereof. In case at any time after the Effective Time any further action is
necessary or desirable to carry out the purposes of this Agreement, the proper
officers and directors of each party to this Agreement shall use commercially
reasonable efforts to take all such action.

            (b) From the date of this Agreement until the Effective Time, each
of the parties shall promptly notify the other in writing (and subsequently keep
the other party informed on a current basis) of any pending or, to the knowledge
of such party, threatened action, proceeding or investigation by any
Governmental Entity or any other person (i) challenging or seeking damages in
connection with the Merger or the conversion of the Common Stock into the Merger
Consideration pursuant to the Merger or (ii) seeking to restrain or prohibit the
consummation of the Merger or otherwise limit the right of Acquiror to own or
operate all or any portion of the business or assets of the Company.

            (c) The Company shall give prompt written notice to Acquiror (and
subsequently keep the Acquiror informed on a current basis), and Acquiror and
Merger Sub shall give prompt written notice to the Company (and subsequently
keep the Company informed on a current basis) of the occurrence, or failure to
occur, of any event, which occurrence or failure to occur would be likely to
cause any representation or warranty contained in this Agreement to be untrue or
inaccurate in any material respect at any time from the date of this Agreement
to the Effective Time. Each party shall use its commercially reasonable efforts
to not take, or omit to take, any action, or enter into any transaction, which
would be expected to cause any of its representations or warranties contained in
this Agreement to be untrue or result in a breach of any covenant made by it in
this Agreement.

      SECTION 7.6 Public Announcements.

            Acquiror and the Company shall consult with each other before
issuing any press release or otherwise making any public statements with respect
to the Merger and shall not issue any such press release or make any such public
statement prior to such consultation, except as may be required by law or any
listing agreement of Acquiror or the Company with any exchange on which the
securities of the Company or Acquiror are traded or quotation service on which
the prices of trades of the Company's or Acquiror's securities are quoted.

      SECTION 7.7 Indemnification and Insurance.

            (a) The certificate of incorporation and bylaws of the Surviving
Corporation shall contain the provisions with respect to indemnification set
forth in the certificate of incorporation and bylaws of the Company on the date
of this Agreement, which provisions shall not be amended, repealed or otherwise
modified for a period of six (6) years after the Effective Time in any manner
that would adversely affect the rights thereunder of persons who at any time
prior to the Effective Time were identified as prospective indemnities under the
certificate of incorporation or bylaws of the Company in respect of actions or
omissions occurring at or prior to the Effective Time (including, without
limitation, the transactions contemplated by this Agreement), unless such
modification is required by applicable law.

            (b) From and after the Effective Time, the Surviving Corporation
shall indemnify, defend and hold harmless the present and former officers,
directors and employees of the Company and the Company Subsidiaries
(collectively, the "Indemnified Parties") against all losses, expenses, claims,
damages, liabilities or amounts that are paid in settlement of, with the
approval of Acquiror and the Surviving Corporation (which approval shall not be
unreasonably withheld), or otherwise in connection with, any claim, action,
suit, proceeding or investigation (a "Claim"), based in whole or in part on the
fact that such person is or was such a director, officer or employee and arising
out of actions or omissions occurring at or prior to the Effective Time
(including, without limitation, the transactions contemplated by this
Agreement), in each case to the fullest extent permitted under Delaware Law (and
shall pay expenses in advance of the final disposition of any such action or
proceeding to each Indemnified Party to the fullest extent permitted under
Delaware Law, upon receipt from the Indemnified Party to whom expenses are
advanced of the undertaking to repay such advances contemplated by Section
145(e) of Delaware Law).

            (c) Without limiting the foregoing, in the event any Claim is
brought against any Indemnified Party (whether arising before or after the
Effective Time) after the Effective Time (i) the Indemnified Parties may retain
its regularly engaged independent legal counsel as of the date of this
Agreement, or other independent legal counsel satisfactory to them provided that
such other counsel shall be reasonably acceptable to Acquiror and the Surviving
Corporation, (ii) the Surviving Corporation shall pay all reasonable fees and
expenses of such counsel for the Indemnified Parties promptly as statements
therefor are received, and (iii) the Surviving Corporation will use its
reasonable efforts to assist in the vigorous defense of any such matter,
provided that the Surviving Corporation shall not be liable for any settlement
of any Claim effected without its written consent, which consent shall not be
unreasonably withheld. Any Indemnified Party wishing to claim indemnification
under this Section 7.7, upon learning of any such Claim, shall notify the
Surviving Corporation (although the failure so to notify the Surviving
Corporation shall not relieve the Surviving Corporation from any liability which
the Surviving Corporation may have under this Section 7.7, except to the extent
such failure prejudices the Surviving Corporation), and shall deliver to the
Surviving Corporation the undertaking contemplated by Section 145(e) of Delaware
Law. The Indemnified Parties as a group may retain one law firm (in addition to
local counsel) to represent them with respect to each such matter unless there
is, under applicable standards of professional conduct (as determined by counsel
to such Indemnified Parties) a conflict on any significant issue between


                                      A-30
<PAGE>

the position of any two or more of such Indemnified Parties, in which event, an
additional counsel as may be required may be retained by such Indemnified
Parties.

            (d) Acquiror shall cause to be maintained in effect for not less
than six (6) years after the Effective Time the current policies of directors'
and officers' liability insurance and fiduciary liability insurance maintained
by the Company with respect to matters occurring prior to the Effective Time;
provided, however, that (i) Acquiror may substitute therefor policies of
substantially the same coverage containing terms and conditions that are
substantially the same for the Indemnified Parties to the extent reasonably
available and (ii) Acquiror shall not be required to pay an annual premium for
such insurance in excess of two hundred percent (200%) of the last annual
premium paid prior to the date of this Agreement, but in such case shall
purchase as much coverage as possible for such amount.

            (e) This Section 7.7 is intended to be for the benefit of, and shall
be enforceable by, the Indemnified Parties referred to herein, their heirs and
personal representatives and shall be binding on Acquiror and Merger Sub and the
Surviving Corporation and their respective successors and assigns. Acquiror
hereby guarantees the Surviving Corporation's obligations pursuant to this
Section 7.7.

            (f) The Company shall use commercially reasonable efforts to
increase its errors and omissions insurance policy coverage to $150,000,000;
provided, however, that if the increase in premium for such increased coverage
exceeds $50,000, the Company shall obtain the maximum policy coverage obtainable
for an increased premium equal to $50,000.

      SECTION 7.8 Employee Benefits Matters.

            (a) Acquiror shall cause the Surviving Corporation to provide
employee benefits under plans, programs and arrangements, which will provide
benefits to the employees of the Company and the Company Subsidiaries
substantially comparable in the aggregate to benefits provided to similarly
situated employees of the Acquiror; provided, however, that nothing herein shall
interfere with the Surviving Corporation's right or obligation to make such
changes to such plans, programs or arrangements as are necessary to conform with
applicable law. Acquiror will cause each employee benefit plan of Acquiror in
which employees of the Company are eligible to participate to take into account
for purposes of eligibility and vesting thereunder the service of such employees
with the Company (and any predecessors of the Company) as if such service were
with Acquiror, to the same extent that such service was credited under a
comparable plan of the Company as reflected on the records of such plan. Unless
otherwise required by law, only employees of the Company who sign and comply
with the Acquiror's standard forms of employment and related agreements will be
eligible to participate in Acquiror's bonus, share and other benefit plans.

            (b) Following the Effective Time, with respect to the Company's
retention bonus plan, Acquiror shall, or shall cause the Surviving Corporation
to honor the letters to employees in respect of such retention bonus plan, all
of which letters are substantially in the form of the letter attached hereto as
Schedule 7.8(b); provided, however, that the employee is on the payroll at the
time any retention bonus is due.


                                      A-31
<PAGE>

            (c) Following the Effective Time, Acquiror shall, or shall cause the
Surviving Corporation to, honor all terms and conditions of the Company's
administrative retention plan and related agreements attached as Schedule
7.8(c).

      SECTION 7.9 HSR Act Matters; Foreign Antitrust Laws.

            Acquiror, Merger Sub and the Company (as may be required pursuant to
the HSR Act and any applicable foreign antitrust or competition law or
regulation) promptly will complete and file all documents required to be filed
with the Federal Trade Commission and the United States Department of Justice or
any foreign Governmental Entity in order to comply with the HSR Act and any
applicable foreign antitrust or competition law or regulation. Acquiror, Merger
Sub and the Company shall furnish promptly all materials thereafter required by
any of the Governmental Entities having jurisdiction over such filings, and
shall take all reasonable actions and shall file and use reasonable best efforts
to have declared effective or approved all documents and notifications with any
such Governmental Entity, as may be required under the HSR Act, other Federal
antitrust laws, or any applicable foreign antitrust or competition law or
regulation for the consummation of the Merger and the other transactions
contemplated hereby. If the Closing does not occur, for whatever reason, unless
the Company shall have paid the Acquiror the Termination Fee, the Company shall
reimburse the Acquiror for one-half (1/2) of all fees paid by the Acquiror in
connection with any filings made pursuant to the HSR Act and any applicable
foreign antitrust or competition law or regulation in connection with this
Agreement. The Company shall reimburse such fees to the Acquiror within five (5)
days after the termination of this Agreement.

      SECTION 7.10 Board Recommendations; Negotiation With Others.

            (a) The Company shall, and shall cause any Company Subsidiary and
the respective affiliates, directors, officers, financial and legal advisors and
other representatives of the Company or the Company Subsidiaries to, cease
immediately all activities, discussions or negotiations, if any, with any person
conducted heretofore with respect to any Acquisition Proposal.

            (b) From and after the date of this Agreement, the Company, the
Company Subsidiaries, and their respective affiliates, directors, officers,
financial or legal advisors or other representatives, will not, directly or
indirectly, (i) take any action to solicit, initiate, facilitate or encourage
any Acquisition Proposal or (ii) engage in negotiations or discussions with, or
disclose any nonpublic information relating to the Company or any of the Company
Subsidiaries or afford access to the properties, books or records of the Company
or any of the Company Subsidiaries to, any person making or which the Company or
any such representative has reason to believe is likely to make an Acquisition
Proposal (or a potential Acquisition Proposal); provided, however, that if at
any time prior to the time that the stockholders of the Company shall have voted
on this Agreement at a meeting held for such purpose pursuant to Section 7.3
hereof, the Company is otherwise in compliance with the Company's obligations
under Section 7.3 and this Section 7.10, the Company, in response to an
unsolicited Acquisition Proposal, may (1) request clarifications from, or
furnish information to, any third party which makes such an unsolicited
Acquisition Proposal, for the purpose of obtaining information reasonably
necessary to ascertain whether such Acquisition Proposal is, or should
reasonably be expected to lead to, a Superior


                                      A-32
<PAGE>

Proposal and (2) if the board of directors of the Company (after consultation
with an independent, nationally recognized investment bank) reasonably
determines in good faith that such Acquisition Proposal is or is reasonably
expected to be a Superior Proposal, participate in discussions or negotiations
with or furnish information to the third party which has made such Acquisition
Proposal, if, in the case of each action to be taken under clause (1) or (2),
(x) each such action is taken subject to a confidentiality agreement with
confidentiality and standstill terms at least as stringent as those contained in
the Confidentiality Agreement, and, to the extent permitted by the terms of any
confidentiality agreement to which the Company is or becomes subject, the
Company has notified Acquiror in writing of the receipt of an Acquisition
Proposal which notice will include a detailed summary of the Acquisition
Proposal and copies of any documentation received by the Company in connection
with such Acquisition Proposal, (y) the board of directors of the Company (after
receiving advice from outside legal counsel to the Company) reasonably
determines in good faith that it is necessary to take each such action in order
to comply with its fiduciary duties under Delaware Law, and (z) the board of
directors of the Company has concluded that such third party is capable of
executing a definitive agreement and consummating a transaction on a reasonable
schedule.

            (c) Notwithstanding anything in this Agreement to the contrary,
Acquiror and the Company agree that the Company may take such actions as are
necessary to divest its Indonesian subsidiary, Fieldston Publications, Inc. and
CapGemini Hagler Bailly LLC (it being recognized that this Agreement has been
made subject to Acquiror's reasonable satisfaction with the terms of any such
divestitures).

            (d) Nothing contained in this Section 7.10 shall prohibit the board
of directors of the Company from, to the extent applicable, complying with Rules
14d-9 and 14e-2 promulgated under the Exchange Act with regard to an Acquisition
Proposal for the Company.

            (e) For purposes of this Agreement, "Acquisition Proposal" means any

            (f) For purposes of this Agreement, "Superior Proposal" means a bona
fide Acquisition Proposal that the board of directors of the Company determines
in good faith (after consultation with its financial advisor and outside legal
counsel) (i) would, if consummated, result in a transaction more favorable to
the Company's stockholders, from a financial point of view, than the
transactions contemplated by this Agreement, taking into account all the terms
and conditions of such Acquisition Proposal, including any proposed break-up
fees or similar devices, expense reimbursement provisions, conditions to
consummation and conditions to execution of a definitive agreement and (ii) is
reasonably capable of being consummated.

and correct as of such date), except where the failure of such representations
and warranties to be true and correct (without giving any effect, solely for

specific date was true and correct as of such date), except where the failure of
such representations and warranties to be true and correct (without giving any
effect, solely for purposes of this Section 8.3, to any materiality or Acquiror
Material Adverse Effect qualification contained therein and reading any
representation or warranty in Article IV and Article V respectively as if that
language were not present in the applicable sections, does not have, and is not
reasonably likely to have, individually or in the aggregate, an Acquiror
Material Adverse Effect; and (b) each of Acquiror and Merger Sub, respectively,
shall have performed and complied in all material respects with all covenants,
obligations, and conditions of this Agreement required to be

            (a) by mutual written consent of each of Acquiror and the Company;

            (b) by either the Company or Acquiror, if the other shall have
breached, or failed to comply with, in any material respect, any of its
obligations under this Agreement or any representation or warranty made by such

within thirty (30) days after written notice thereof or such breach, by its
nature or timing, cannot be cured within such a 30-day period;

jurisdiction or any Governmental Entity preventing or prohibiting consummation
of the Merger shall have become final and nonappealable;

            (d) by either Acquiror or the Company, if the Merger and the
Agreement shall fail to receive the requisite vote for approval and adoption by
the stockholders of the Company at the Stockholders' Meeting;

            (e) by either the Company or Acquiror, if the merger shall not have
been consummated on the date which is one hundred eighty (180) days after the
date hereof (the "Termination Date"); provided, however, that the right to
terminate this Agreement under this Section 9.1(e) shall not be available to any
party who is in breach of this Agreement or whose failure to fulfill any
obligation under this Agreement has been the cause of, or resulted in, the
failure of the Effective Time to occur on or before the Termination Date;
provided, further, that the Termination Date shall be automatically extended to
allow sufficient time for any cure, notice and termination periods pursuant to
Section 9.1(h) to expire;

            (f) by Acquiror, if the Company or its board of directors shall have
accepted or recommended to the stockholders of the Company a Superior Proposal;

have accepted or recommended to the stockholders of the Company a Superior
Proposal; provided that the Company and its board of directors shall have
complied, in all material respects, with their obligations under Section 7.10;


                                      A-36

Company and subject to the following conditions: (i) in the event that either
the Company or the Acquiror becomes aware of a Company Material Adverse Effect,
such party shall immediately provide written notice of the specific Company
Material Adverse Effect (the "MAE Notice") to the other party; (ii) upon either
receipt or delivery of an MAE Notice, the Company shall have thirty (30) days to
cure such Company Material Adverse Effect; and (iii) if such Company Material
Adverse Effect is not cured by the Company within such thirty-day period, then
following thirty (30) days from receipt or delivery of the MAE Notice, Acquiror
shall have a further thirty (30) days to terminate this Agreement or else shall
be deemed to waive the right to terminate (or not consummate the transactions
hereunder) as a result of such Company Material Adverse Effect that gave rise to
the specific MAE Notice (for the avoidance of doubt, sixty (60) days from the
receipt or delivery of the original MAE Notice);

            (i) by Acquiror, if any of the stockholders who are parties to the
Voting Agreement shall have breached in any material respect any representation,
warranty, covenant or agreement thereof and such breach has not been promptly
cured after written notice to any such stockholder; provided, however, that such
breach shall be of the kind that denies Acquiror the material benefits
contemplated by the Voting Agreement.

      SECTION 9.2 Effect of Termination.

            (a) Except as provided in Section 9.2(b), Section 9.3 or Section

this Agreement shall forthwith become void, there shall be no liability on the
part of Acquiror, Merger Sub or the Company or any of their respective officers

any willful breach of this Agreement provided, however, that no party hereto
shall be liable for any consequential or punitive damages.

9.1(g) or (ii) Acquiror terminates this Agreement pursuant to Section 9.1(f),

Acquiror by wire transfer in immediately available funds a fee of Five Million

            (c) Each party hereto acknowledges and agrees that any controversy

difficult issues, and therefore each party hereby irrevocably and
unconditionally waives any right such party may have to a trial by jury in

                 [LETTERHEAD OF BANC OF AMERICA SECURITIES LLC]

                                  June 19, 2000

Board of Directors
Hagler Bailly, Inc.
1530 Wilson Blvd.
Suite 400
Arlington, VA 22209

Members of the Board of Directors:

      You have requested our opinion as to the fairness from a financial point
of view to the stockholders of Hagler Bailly, Inc. (the "Company") of the
consideration proposed to be received by such stockholders in the proposed
merger (the "Merger") of the Company with a wholly owned subsidiary of PA
Consulting Group, Inc. (the "Purchaser"). Pursuant to the terms of the Agreement
and Plan of Merger, dated as of June 19, 2000 (the "Agreement"), among the
Company, the Purchaser, PA Holdings Inc. and PA Holdings Limited, the ultimate
parent of the Purchaser, the Company will become a wholly owned subsidiary of
the Purchaser, and stockholders of the Company will receive for each share of
common stock, par value $.01 per share, of the Company (the "Company Common
Stock"), held by them, other than shares held in treasury or held by the
Purchaser or any affiliate of the Purchaser or as to which dissenters' or
appraisal rights have been perfected, consideration equal to $5.32 per share,
subject to adjustment. The terms and conditions of the Merger are more fully set
out in the Agreement.

      For purposes of the opinion set forth herein, we have:

            (i) reviewed certain publicly available financial statements and
      other business and financial information of the Company;

            (ii) reviewed certain internal financial statements and other
      financial and operating data concerning the Company;

            (iii) analyzed certain financial forecasts prepared in conjunction
      with the management of the Company and considered the present financial
      condition of the Company;

            (iv) discussed the past and current operations, financial condition
      and prospects of the Company with senior executives and members of the
      Board of Directors of the Company, including, without limitation, their
      belief that the Company would suffer


                                       B-1
<PAGE>

      a significant loss of key consultants in the event that a strategic
      transaction does not occur in the near future;

            (v) at the request of the Board of Directors of the Company, spoke
      with a number of potential purchasers concerning their possible interest
      in the Company, and noted that no potential purchaser other than the
      Purchaser presented a proposal to acquire the Company;

            (vi) reviewed the reported prices and trading activity for the
      Company Common Stock;

            (vii) compared the financial performance of the Company and the
      prices and trading activity of the Company Common Stock with that of
      certain other publicly traded companies we deemed relevant;

            (viii) compared certain financial terms to financial terms, to the
      extent publicly available, of certain other business combination
      transactions we deemed relevant;

            (ix) participated in discussions and negotiations among
      representatives of the Company and the Purchaser and their legal advisors;

            (x) reviewed the Agreement, including the form of Earnout Agreement
      (as defined in the Agreement) attached thereto as Schedule A, and certain
      related documents; and

            (xi) performed such other analyses and considered such other factors
      as we have deemed appropriate.

      We have assumed and relied upon, without independent verification, the
accuracy and completeness of the financial and other information reviewed by us
for the purposes of this opinion, including the Company's representation
regarding the number of shares and options outstanding. We have with your
consent also assumed, and relied upon the representations of management of the
Company that it believes, that the Earnout Agreement will be executed on terms
substantially similar to the form thereof included in the Agreement and any
difference between the actual Earnout Agreement and the form thereof included in
the Agreement will not materially affect the consideration paid to the
stockholders of the Company in the Merger. With respect to the financial
forecasts, we have assumed, and relied upon, without independent verification,
the views of management of the Company that they have been reasonably prepared
on bases reflecting the best currently available estimates and good faith
judgments of the future financial performance of the Company. We have not made
any independent valuation or appraisal of the assets or liabilities of the
Company, nor have we been furnished with any such appraisals.

      We have acted as financial advisor to the Board of Directors of the
Company in connection with this transaction and will receive a fee for our
services, including a fee, which is contingent upon the consummation of the
Merger. In the past, Banc of America Securities LLC


                                       B-2
<PAGE>

or its affiliates have provided financial advisory and financing services for
the Company and have received fees for the rendering of these services. In the
ordinary course of our businesses, we and our affiliates may actively trade the
debt and equity securities of the Company and the Purchaser for our own account
or for the accounts of customers and, accordingly, we or our affiliates may at
any time hold long or short positions in such securities. We serve as the
Company's lender under a senior credit facility and have received and expect to
receive fees for the rendering of such services.

      It is understood that this letter is for the benefit and use of the Board
of Directors of the Company in connection with and for purposes of its
evaluation of the Merger and is not on behalf of, and shall not confer rights or
remedies upon, any person other than the Board of Directors. This opinion may
not be disclosed, referred to, or communicated (in whole or in part) to any
third party for any purpose whatsoever except with our prior written consent in
each instance. However, this opinion may be included in its entirety in any
filing made by the Company in respect of the transactions contemplated by the
Agreement with the Securities and Exchange Commission, so long as this opinion
is reproduced in such filing in full and any description of or reference to us
or summary of this opinion in such filing is in a form acceptable to us and our
counsel. In furnishing this opinion, we do not admit that we are experts within
the meaning of the term "experts" as used in the Securities Act of 1933, as
amended (the "Securities Act"), and the rules and regulations promulgated
thereunder, nor do we admit that this opinion constitutes a report or valuation
within the meaning of Section 11 of the Securities Act. Our opinion is
necessarily based on economic, market and other conditions as in effect on, and
the information made available to us as of, the date hereof. It should be
understood that subsequent developments may affect this opinion and we do not
have any obligation to update, revise, or reaffirm this opinion. In addition,
BAS expresses no opinion or recommendation as to how the stockholders of the
Company should vote at the stockholders' meeting held in connection with the
Merger.

      Based upon and subject to the foregoing, including the various assumptions
and limitations set forth herein, we are of the opinion on the date hereof that
the consideration to be received by the Company's stockholders in the proposed
Merger is fair from a financial point of view to the Company's stockholders.

                                                  Very truly yours,

                                                  BANC OF AMERICA SECURITIES LLC

                           SECTION 262 OF THE DELAWARE
                             GENERAL CORPORATION LAW

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

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

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

                  (2) Notwithstanding paragraph (1) of this subsection,
appraisal rights under this section shall be available for the shares of any
class or series of stock of a constituent corporation if the holders thereof are
required by the


                                      C-1
<PAGE>

terms of an agreement of merger or consolidation pursuant to 251, 252, 254, 257,
258, 263 and 264 of this title to accept for such stock anything except:

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

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

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

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

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

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

            (d) Appraisal rights shall be perfected as follows:

                  (1) If a proposed merger or consolidation for which appraisal
rights are provided under this section is to be submitted for approval at a
meeting of stockholders, the corporation, not less than 20 days prior to the
meeting, shall notify each of its stockholders who was such on the record date
for such meeting with respect to shares for which appraisal rights are available
pursuant to subsections (b) or (c) hereof that appraisal rights are available
for any or all of the shares of the constituent corporations, and shall include
in such notice a copy of this section. Each stockholder electing to demand the
appraisal of such stockholder's


                                      C-2
<PAGE>

shares shall deliver to the corporation, before the taking of the vote on the
merger or consolidation, a written demand for appraisal of such stockholder's
shares. Such demand will be sufficient if it reasonably informs the corporation
of the identity of the stockholder and that the stockholder intends thereby to
demand the appraisal of such stockholder's shares. A proxy or vote against the
merger or consolidation shall not constitute such a demand. A stockholder
electing to take such action must do so by a separate written demand as herein
provided. Within 10 days after the effective date of such merger or
consolidation, the surviving or resulting corporation shall notify each
stockholder of each constituent corporation who has complied with this
subsection and has not voted in favor of or consented to the merger or
consolidation of the date that the merger or consolidation has become effective;
or

                  (2) If the merger or consolidation was approved pursuant to
228 or 253 of this title, each constituent corporation, either before the
effective date of the merger or consolidation or within ten days thereafter,
shall notify each of the holders of any class or series of stock of such
constituent corporation who are entitled to appraisal rights of the approval of
the merger or consolidation and that appraisal rights are available for any or
all shares of such class or series of stock of such constituent corporation, and
shall include in such notice a copy of this section; provided that, if the
notice is given on or after the effective date of the merger or consolidation,
such notice shall be given by the surviving or resulting corporation to all such
holders of any class or series of stock of a constituent corporation that are
entitled to appraisal rights. Such notice may, and, if given on or after the
effective date of the merger or consolidation, shall, also notify such
stockholders of the effective date of the merger or consolidation. Any
stockholder entitled to appraisal rights may, within 20 days after the date of
mailing of such notice, demand in writing from the surviving or resulting
corporation the appraisal of such holder's shares. Such demand will be
sufficient if it reasonably informs the corporation of the identity of the
stockholder and that the stockholder intends thereby to demand the appraisal of
such holder's shares. If such notice did not notify stockholders of the
effective date of the merger or consolidation, either (i) each such constituent
corporation shall send a second notice before the effective date of the merger
or consolidation notifying each of the holders of any class or series of stock
of such constituent corporation that are entitled to appraisal rights of the
effective date of the merger or consolidation or (ii) the surviving or resulting
corporation shall send such a second notice to all such holders on or within 10
days after such effective date; provided, however, that if such second notice is
sent more than 20 days following the sending of the first notice, such second
notice need only be sent to each stockholder who is entitled to appraisal rights
and who has demanded appraisal of such holder's shares in accordance with this
subsection. An affidavit of the secretary or assistant secretary or of the
transfer agent of the corporation that is required to give either notice that
such notice has been given shall, in the absence of fraud, be prima facie
evidence of the facts stated therein. For purposes of determining the
stockholders entitled to receive either notice, each constituent corporation may
fix,


                                      C-3
<PAGE>

in advance, a record date that shall be not more than 10 days prior to the date
the notice is given, provided, that if the notice is given on or after the
effective date of the merger or consolidation, the record date shall be such
effective date. If no record date is fixed and the notice is given prior to the
effective date, the record date shall be the close of business on the day next
preceding the day on which the notice is given.

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

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

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

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

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

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

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

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