ITEM 5.  OTHER EVENTS

     Pursuant to an Agreement and Plan of Merger and Reorganization dated
September 9, 1998 (the "Reorganization Agreement") among FCG, Foxtrot
Acquisition Sub, Inc., a Delaware corporation and wholly-owned subsidiary of FCG
("Merger Sub"), and ISCG, and subject to the conditions set forth therein
(including approval by the stockholders of FCG and shareholders ISCG), Merger
Sub will be merged with and into ISCG (the "Merger"), with each share of ISCG
Common Stock being converted into the right to receive 0.77 ("FCG Common Stock")
shares of FCG's Common Stock.  In addition, FCG will assume all options
outstanding under ISCG's Amended and Restated Stock Option Plan and all warrants
outstanding and issued by ISCG.  If the Merger is consummated, ISCG Common Stock
will be deregistered under the Exchange Act and delisted from the Nasdaq
National Market.

     At the effective time of the Merger (the "Effective Time"), the separate
existence of Merger Sub will cease, and ISCG will continue as the surviving
corporation and as a wholly-owned subsidiary of FCG ("Surviving Corporation").
The officers and directors of the Surviving Corporation immediately after the
Effective Time shall be the officers and directors of Merger Sub immediately
prior to the Effective Time and shall serve as the officers and directors of the
Surviving Corporation until their respective successors are elected and
qualified or duly appointed, as the case may be.  The Articles of Incorporation
of the Surviving Corporation shall be amended and restated as of the Effective
Time to conform to the Certificate of Incorporation of Merger Sub as in effect
immediately prior to the Effective Time; PROVIDED, HOWEVER, that at the
Effective Time the Articles of Incorporation of the Surviving Corporation shall
be amended so that the name of the Surviving Corporation shall be Integrated
Systems Consulting Group, Inc.  The Bylaws of the Surviving Corporation shall be
amended and restated as of the Effective Time to conform to the Bylaws of Merger
Sub as in effect immediately prior to the Effective Time.

     REPRESENTATIONS, WARRANTIES, COVENANTS AND CLOSING CONDITIONS.  The
Reorganization Agreement contains customary representations and warranties on
the part of ISCG and FCG, and the consummation of the Merger is subject to
customary closing conditions, including, without limitation, approval by the
stockholders of ISCG and FCG, regulatory approval and the occurrence of no
material adverse effect with respect to a party.  The Reorganization Agreement
also contains covenants regarding the activities of ISCG prior to the earlier of
the Effective Time and the termination of the Reorganization Agreement.  ISCG
has agreed to, among other things, conduct its business in the ordinary course,
in accordance with past practices and in compliance with applicable laws and the
requirements of all of its material contracts.  In addition, a number of
corporate actions by ISCG during the period pending the closing of the Merger
require FCG's approval, including dividends, issuances of capital stock,
borrowings, capital expenditures and stock option grants above specified
minimums.

     TERMINATION OF REORGANIZATION AGREEMENT.  The Reorganization Agreement may
be terminated prior to the Effective Time, whether before or after approval of
the Reorganization Agreement and the Merger by the shareholders of ISCG: (i) by
mutual written consent of the Boards of Directors of FCG and ISCG; (ii) subject
to certain exceptions, by either FCG or ISCG if the Merger shall not have been
consummated by January 31, 1999; (iii) by either FCG or ISCG in connection with
certain legal or governmental actions having the effect of permanently
restraining,


                                          1.

enjoining or otherwise prohibiting the Merger; (iv) subject to certain
limitations, by FCG or ISCG if the ISCG Special Meeting shall have been held and
the Reorganization Agreement and the Merger shall not have been approved by the
necessary vote of the ISCG shareholders; (v) by FCG if (at any time prior to the
adoption and approval of the Reorganization Agreement and approval of the Merger
by the ISCG shareholders) a "Triggering Event" (as defined in the Reorganization
Agreement) shall have occurred; (vi) subject to certain limitations, by FCG or
ISCG if the FCG Special Meeting shall have been held and the issuance of FCG
Common Stock in the Merger shall not have been approved by the necessary vote of
the FCG stockholders; (vii) by FCG, subject to certain limitations, if any of
the representations and warranties of ISCG contained in the Reorganization
Agreement shall be or have become materially inaccurate, or if any of ISCG's
covenants contained in the Reorganization Agreement shall have been breached in
any material respect such that certain conditions precedent to Closing would not
be satisfied as of the time of such breach or as of the time such representation
or warranty became untrue; or (viii) by ISCG, subject to certain limitations, if
any of the representations and warranties of FCG contained in the Reorganization
Agreement shall be or have become materially inaccurate, or if any of FCG's
covenants contained in the Reorganization shall have been breached in any
material respect such that certain conditions precedent to Closing would not be
satisfied as of the time of such breach or as of the time such representation or
warranty became untrue.

     VOTING AGREEMENTS.  As an inducement to FCG to enter into the
Reorganization Agreement, each of David S. Lipson, Technology Leaders II,
Safeguard Scientifics, Inc. and Warrant and Stock Trust (individually, a "ISCG
Voting Agreement Shareholder" and, collectively, the "ISCG Voting Agreement
Shareholders") has entered into a Voting Agreement dated as of September 9, 1998
(individually, a "ISCG Voting Agreement" and, collectively, the "ISCG Voting
Agreements") with FCG.  The number of shares of ISCG Common Stock beneficially
owned by each of the ISCG Voting Agreement Shareholders is set forth on Schedule

who beneficially own an aggregate of 5,253,996 (includes 679,723 shares of ISCG
Common Stock issuable upon the exercise of currently exercisable warrants)
outstanding shares of ISCG Common Stock (representing approximately 60.0% of the
shares of ISCG Common Stock as of August 31, 1998) have agreed that, prior to
the Expiration Date, they will vote their shares of ISCG Common Stock in favor
of: (i) approval of the Merger; (ii) approval and adoption of the Reorganization
Agreement; and (iii) each of the other actions contemplated by the
Reorganization Agreement.  The ISCG Voting Agreement Shareholders have also
delivered to FCG irrevocable proxies with respect to the matters covered by the
ISCG Voting Agreements.  In addition, the ISCG Voting Agreement Shareholders
have agreed not to transfer any securities of ISCG owned by them unless and
until the proposed transferee of such ISCG securities shall have (i) executed a
counterpart of the ISCG Voting Agreement and an irrevocable proxy and (ii)
agreed to hold such ISCG securities subject to all of the terms and provisions
of the ISCG Voting Agreement. FCG did not pay any additional consideration to
any ISCG Voting Agreement Shareholders in connection with the execution and
delivery of the ISCG Voting Agreements.

     As an inducement to ISCG to enter into the Reorganization Agreement, each
of James A. Reep, Thomas A. Reep and Brent A. Hanson (individually, a "FCG

<PAGE>

Common Stock beneficially owned by each of the FCG Voting Agreement Stockholders
as of September 9, 1998 is set forth on Schedule II to this Current Report on
Form 8-K.  The FCG Voting Agreement Stockholders, who beneficially own an
aggregate of 4,339,072 outstanding shares of FCG Common Stock (representing
approximately 27.3% of the shares of FCG Common Stock as of August 31,1998) have
agreed that, prior to the Expiration Date, they will vote their shares of FCG
Common Stock in favor (i) of the issuance of the shares of FCG Common Stock to
be issued in the Merger and (ii) each of the other actions contemplated by the
Reorganization Agreement.  The FCG Voting Agreement Stockholders have also
delivered to ISCG irrevocable proxies with respect to the matters covered by the
FCG Voting Agreements.  The FCG Voting Agreement Stockholders have also agreed,
in certain instances, to require any party to whom their shares of FCG Common
Stock may be sold, pledged, granted an option to purchase, or otherwise
transferred to execute a counterpart of the FCG Voting Agreement and agree to
hold such FCG securities subject to all the terms and provisions of the FCG
Voting Agreements. ISCG did not pay any additional consideration to the FCG
Voting Agreement Stockholders in connection with the execution and delivery of
the FCG Voting Agreements.

     AFFILIATE AGREEMENTS.  As an inducement to ISCG to enter into the 
Reorganization Agreement, each of David S. Lipson, Technology Leaders II,

Affiliate" and, collectively, the "ISCG Affiliates") has entered into an 
agreement (each an "ISCG Affiliate Agreement" and, collectively the "ISCG 
Affiliate Agreements") whereby each ISCG Affiliate agreed not to effect any 
sale, transfer or other disposition of the FCG Common Stock received by such 
ISCG Affiliate in the Merger unless: (i) such sale, transfer or other 
disposition is made in conformity with the volume and other requirements of 
Rule 145 under the Securities Act of 1933, as amended (the "Securities Act"), 
as evidenced by a broker's letter and a representation letter executed by the 
ISCG Affiliate (reasonably satisfactory in form and content to FCG), each 
stating that such requirements have been met; (ii) legal counsel reasonably 
satisfactory to FCG shall have advised FCG in a written opinion letter 
(reasonably satisfactory in form and content to FCG), upon which FCG may 
rely, that such sale, transfer or other disposition will be exempt from 
registration under the Securities Act; (iii) such sale, transfer or other 
disposition is effected pursuant to an effective registration statement under 
the Securities Act; or (iv) an authorized representative of the Securities

action, or that the staff of the Commission would not recommend that the 
Commission take action, with respect to such proposed sale, transfer or other 
disposition, and a copy of such written advice and all other related 
communications with the Commission shall have been delivered to FCG.

     In addition, so as to help ensure that the Merger will be treated as a
pooling of interests for accounting and financial reporting purposes, the ISCG
Affiliate Agreements provide that during the period contemplated by the
Commission's Staff Accounting Bulletin Number 65 until the earlier of (i) FCG's
public announcement of financial results covering at least 30 days of combined
operations of FCG and ISCG or (ii) the Reorganization Agreement is terminated in
accordance with its terms, no ISCG Affiliate shall sell, exchange, transfer,
pledge, distribute or otherwise dispose of or grant any option, establish any
"short" or put-equivalent position with respect to or enter into any similar
transaction (through derivative's or otherwise) intended or having the effect,
directly or indirectly, to reduce such ISCG Affiliate's risk relative to:  (i)
any ISCG Common Stock (except pursuant to and upon consummation of the Merger);
or (ii) any FCG Common Stock received by such ISCG Affiliate in the Merger or
upon exercise of options


                                          3.

assumed by FCG in the Merger.  Provided certain conditions are met, the ISCG
Affiliate Agreements provide for certain exceptions to the foregoing
restrictions on transfer relating to:  (i) certain DE MINIMIS transfers; (ii)
transfers in payment of the exercise price of options to purchase ISCG Common
Stock or FCG Common Stock; (iii) charitable donations; or (iv) transfers to

and fair to, and in the best interests of, the Company and its shareholders,

Company adopt and approve this Agreement and approve the Merger.

and inducement to Parent's willingness to enter into this Agreement, each of the
affiliate shareholders of the Company listed on Exhibit B-1 hereto is entering
into a Voting Agreement substantially in the form attached hereto as Exhibit
C-1; and as a condition and inducement to the Company's willingness to enter
into this Agreement, each of the affiliate stockholders of Parent listed on
Exhibit B-2 hereto is entering into a Voting Agreement substantially in the form
attached hereto as Exhibit C-2.
 
    F.  Concurrently with the execution of this Agreement, and as a condition
and inducement to Parent's willingness to enter into this Agreement, each of the
Persons identified on Exhibit D-1 hereto is entering into an Affiliate Agreement
substantially in the form attached hereto as Exhibit E-1. Concurrently with the
execution of this Agreement, and as a condition and inducement to the Company's

form attached hereto as Exhibit E-2.
 
                                   AGREEMENT
 
    The parties to this Agreement, intending to be legally bound, agree as
follows:

of Cooley Godward LLP, Five Palo Alto Square, 3000 El Camino Real, Palo Alto,
California, at 10:00 a.m. on a date to be designated by Parent (the "CLOSING
DATE"), which shall be no later than the second business day after satisfaction
or waiver of the conditions set forth in Sections 6 and 7. Contemporaneously
with or as promptly as practicable after the Closing, properly executed articles
of merger conforming to the requirements of the PBCL (the "ARTICLES OF MERGER")
shall be filed with the Department of State of the Commonwealth of Pennsylvania
and a properly executed certificate of merger conforming to the requirements of
the DGCL shall be filed with the Secretary of State of the State of Delaware.
The Merger shall take effect at the later of (a) the time the Articles of Merger

Pennsylvania, (b) the time the certificate of merger is accepted for filing by
the Secretary of State of the State of Delaware and (c) at such later time as
may be specified in the Articles of Merger (the "EFFECTIVE TIME").
 
    1.4  CERTIFICATE OF INCORPORATION AND BYLAWS; DIRECTORS AND
OFFICERS.  Unless otherwise determined by Parent prior to the Effective Time:
 
        (A) the Articles of Incorporation and Bylaws of the Surviving
    Corporation shall be amended and restated as of the Effective Time to
    conform to the Amended and Restated Articles of Incorporation and Amended
    and Restated Bylaws substantially in the form attached hereto as Exhibits
    F-1 and F-2, respectively; PROVIDED, HOWEVER, that at the Effective Time the
    Articles of Incorporation of the Surviving Corporation shall be amended so
    that the name of the Surviving Corporation shall be Integrated Systems
    Consulting Group, Inc.; and
 
        (B) the directors and officers of the Surviving Corporation immediately
    after the Effective Time shall be the directors and officers of Merger Sub
    immediately prior to the Effective Time, until their respective successors
    are elected and qualified or duly appointed, as the case may be.
 
    1.5  CONVERSION OF SHARES.
 
        (A) Subject to Section 1.5(d), at the Effective Time, by virtue of the
    Merger and without any further action on the part of Parent, Merger Sub, the
    Company or any shareholder of the Company:
 
            (I) any shares of Company Common Stock then held by the Company or
       any subsidiary of the Company (or held in the Company's treasury) shall
       be canceled;
 
            (II) any shares of Company Common Stock then held by Parent, Merger
       Sub or any other subsidiary of Parent shall be canceled;
 
           (III) except as provided in clauses "(i)" and "(ii)" above and
       subject to Sections 1.5(b) and (d) and Section 1.9, each share of Company
       Common Stock then outstanding shall be converted into the right to
       receive 0.77 of a share of Parent Common Stock; and
 
           (IV) each share of the common stock, no par value per share, of
       Merger Sub then outstanding shall be converted into one share of common
       stock of the Surviving Corporation.
 
        (B) The fraction of a share of Parent Common Stock into which each
    outstanding share of Company Common Stock is to be converted pursuant to
    Section 1.5(a)(iii) (as such fraction may be adjusted in accordance with
    this Section 1.5(b)) is referred to as the "EXCHANGE RATIO." If, between the
    date of this Agreement and the Effective Time, the outstanding shares of
    Company Common Stock or Parent Common Stock are changed into a different
    number or class of shares by reason of any stock split, stock dividend,
    reverse stock split, reclassification, recapitalization or other similar
    transaction, then the Exchange Ratio shall be appropriately adjusted.
 
                                       2
<PAGE>
        (C) If any shares of Company Common Stock outstanding immediately prior
    to the Effective Time are unvested or are subject to a repurchase option,
    risk of forfeiture or other condition under any applicable restricted stock
    purchase agreement or other agreement with the Company, then the shares of
    Parent Common Stock issued in exchange for such shares of Company Common
    Stock will also be unvested and subject to the same repurchase option, risk
    of forfeiture or other condition, and the certificates representing such
    shares of Parent Common Stock may accordingly be marked with appropriate
    legends. The Company shall take all action that may be necessary to ensure
    that, from and after the Effective Time, Parent is entitled to exercise any
    such repurchase option or other right set forth in any such restricted stock
    purchase agreement or other agreement.
 
        (D) No fractional shares of Parent Common Stock shall be issued in
    connection with the Merger, and no certificates for any such fractional
    shares shall be issued. In lieu of such fractional shares, any holder of
    Company Common Stock who would otherwise be entitled to receive a fraction
    of a share of Parent Common Stock (after aggregating all fractional shares
    of Parent Common Stock issuable to such holder) shall, upon surrender of
    such holder's Company Stock Certificate(s) (as defined in Section 1.7), be
    paid in cash the dollar amount (rounded to the nearest whole cent), without
    interest, determined by multiplying such fraction by the closing price of a
    share of Parent Common Stock on Nasdaq on the Effective Date.
 
    1.6  STOCK OPTIONS AND WARRANTS.  At the Effective Time, all Company Options
(as defined in Section 2.3(b)) shall be assumed by Parent in accordance with
Section 5.5, and all Company Warrants (as defined in Section 2.3(c)) shall be
assumed by Parent in accordance with Section 5.7.
 
    1.7  CLOSING OF THE COMPANY'S TRANSFER BOOKS.  At the Effective Time: (a)
all shares of Company Common Stock outstanding immediately prior to the
Effective Time shall automatically be canceled and retired and shall cease to
exist, and all holders of certificates representing shares of Company Common
Stock that were outstanding immediately prior to the Effective Time shall cease
to have any rights as shareholders of the Company; and (b) the stock transfer
books of the Company shall be closed with respect to all shares of Company
Common Stock outstanding immediately prior to the Effective Time. No further
transfer of any such shares of Company Common Stock shall be made on such stock
transfer books after the Effective Time. If, after the Effective Time, a valid
certificate previously representing any of such shares of Company Common Stock
(a "COMPANY STOCK CERTIFICATE") is presented to the Exchange Agent (as defined
in Section 1.8) or to the Surviving Corporation or Parent, such Company Stock
Certificate shall be canceled and shall be exchanged as provided in Section 1.8.
 
    1.8  EXCHANGE OF CERTIFICATES.
 
        (A) Prior to the Closing Date, Parent shall select a reputable bank or
    trust company to act as exchange agent in the Merger (the "EXCHANGE AGENT").
    Promptly after the Effective Time, Parent shall deposit with the Exchange
    Agent (i) certificates representing the shares of Parent Common Stock
    issuable pursuant to this Section 1 and (ii) cash sufficient to make
    payments in lieu of fractional shares in accordance with Section 1.5(d). The
    shares of Parent Common Stock and cash amounts so deposited with the
    Exchange Agent, together with any dividends or distributions received by the
    Exchange Agent with respect to such shares, are referred to collectively as
    the "EXCHANGE FUND."
 
        (B) As soon as practicable after the Effective Time, the Exchange Agent
    will mail to the registered holders of Company Stock Certificates (i) a
    letter of transmittal in customary form and containing such provisions as
    Parent may reasonably specify (including a provision confirming that
    delivery of Company Stock Certificates shall be effected, and risk of loss
    and title to Company Stock Certificates shall pass, only upon delivery of
    such Company Stock Certificates to the Exchange Agent), and (ii)
    instructions for use in effecting the surrender of Company Stock
    Certificates in exchange for certificates representing Parent Common Stock.
    Subject to Section 1.5(d), upon surrender of a Company Stock Certificate to
    the Exchange Agent for exchange, together with a duly executed letter of
    transmittal and such other documents as may be reasonably required by the
 
                                       3
<PAGE>
    Exchange Agent or Parent, (A) the holder of such Company Stock Certificate
    shall be entitled to receive in exchange therefor a certificate representing
    the number of shares of Parent Common Stock that such holder has the right
    to receive pursuant to the provisions of Section 1.5(a)(iii) together with
    any cash in lieu of fractional share(s) pursuant to the provisions of
    Section 1.5(d), and (B) the Company Stock Certificate so surrendered shall
    be canceled. Until surrendered as contemplated by this Section 1.8(b), each
    Company Stock Certificate shall be deemed, from and after the Effective
    Time, to represent only the right to receive shares of Parent Common Stock
    (and cash in lieu of any fractional share of Parent Common Stock) as
    contemplated by Section 1.5. If any Company Stock Certificate shall have
    been lost, stolen or destroyed, Parent may, in its discretion and as a
    condition precedent to the issuance of any certificate representing Parent
    Common Stock, require the owner of such lost, stolen or destroyed Company
    Stock Certificate to provide an appropriate affidavit and to deliver a bond
    (in such sum as Parent may reasonably direct) as indemnity against any claim
    that may be made against the Exchange Agent, Parent or the Surviving
    Corporation with respect to such Company Stock Certificate.
 
        (C) No dividends or other distributions declared or made with respect to
    Parent Common Stock with a record date after the Effective Time shall be
    paid to the holder of any unsurrendered Company Stock Certificate with
    respect to the shares of Parent Common Stock represented thereby, until such
    holder surrenders such Company Stock Certificate in accordance with this
    Section 1.8 (at which time such holder shall be entitled to receive all such
    dividends and distributions, without interest).
 
        (D) Any portion of the Exchange Fund that remains undistributed to
    holders of Company Stock Certificates as of the date 180 days after the date
    on which the Merger becomes effective shall be delivered to Parent upon
    demand, and any holders of Company Stock Certificates who have not
    theretofore surrendered their Company Stock Certificates in accordance with
    this Section 1.8 shall thereafter look only to Parent for satisfaction of
    their claims for Parent Common Stock, cash in lieu of fractional shares of
    Parent Common Stock and any dividends or distributions with respect to
    Parent Common Stock.
 
        (E) Each of the Exchange Agent, Parent and the Surviving Corporation
    shall be entitled to deduct and withhold from any consideration payable or
    otherwise deliverable pursuant to this Agreement to any holder or former
    holder of Company Common Stock such amounts as may be required to be
    deducted or withheld therefrom under the Code or under any provision of
    state, local or foreign tax law or under any other applicable Legal
    Requirement. To the extent such amounts are so deducted or withheld, such
    amounts shall be treated for all purposes under this Agreement as having
    been paid to the Person to whom such amounts would otherwise have been paid.
 
        (F) Neither Parent nor the Surviving Corporation shall be liable to any
    holder or former holder of Company Common Stock with respect to any shares
    of Parent Common Stock (or dividends or distributions with respect thereto),
    or for any cash amounts, delivered to any public official pursuant to any
    applicable abandoned property, escheat or similar Legal Requirement.
 
    1.9  DISSENTING SHARES.  Notwithstanding anything in this Agreement to the
contrary, shares, if any, of Company Common Stock that are issued and
outstanding immediately prior to the Effective Time that are held by any
shareholder who has not voted such shares in favor of the Merger and who shall
have delivered a written notice of intention to demand payment of fair value of
such shares in the manner provided in Section 1574 of the PBCL ("DISSENTING
SHARES") shall not be converted into or be exchangeable for the right to receive
the consideration provided in Section 1.5(a)(iii) (or cash in lieu of fractional
shares in accordance with Section 1.5(d)) unless and until such holder shall
have failed to perfect or shall have effectively withdrawn or lost his right to
be paid fair value under the PBCL. If such holder shall have failed to perfect
or have effectively withdrawn or lost such right, his shares of Company Common
Stock shall thereupon be deemed to have been converted into and to have become
exchangeable for, at the Effective
 
                                       4
<PAGE>
Time, the right to receive the consideration provided in Section 1.5(a)(iii) (or
cash in lieu of fractional shares in accordance with Section 1.5(d)) without any
interest thereon.
 
    1.10  TAX CONSEQUENCES.  For federal income tax purposes, the Merger is
intended to constitute a reorganization within the meaning of Section 368 of the
Code. The parties to this Agreement hereby adopt this Agreement as a "plan of
reorganization" within the meaning of Sections 1.368-2(g) and 1.368-3(a) of the
United States Treasury Regulations.
 
    1.11  ACCOUNTING CONSEQUENCES.  For accounting purposes, the Merger is
intended to be treated as a "pooling of interests."
 
    1.12  FURTHER ACTION.  If, at any time after the Effective Time, any further
action is determined by Parent to be necessary or desirable to carry out the
purposes of this Agreement or to vest the Surviving Corporation with full right,
title and possession of and to all rights and property of Merger Sub and the
Company, the officers and directors of the Surviving Corporation and Parent
shall be fully authorized (in the name of Merger Sub, in the name of the Company
and otherwise) to take such action.

    specification, documentation, performance standard, representation or
    statement made or provided by or on behalf of the Company, and, to the best
    of the knowledge of the Company, there is no basis for any such claim. To

    and/or use the century portion of any date fields without special
    processing; and (ii) respond to all date elements and date input so as to
    resolve any ambiguity as to century in a disclosed, defined and
    pre-determined manner and provide date information in ways which are
    unambiguous as to century, either by permitting or requiring the century to
    be specified or where the data element is represented without a century, the
    correct century is unambiguous for all manipulations involving that element.

    (ii) self-funded medical, dental or other similar Plan. None of the Plans
    identified in Part 2.16(a) of the Company Disclosure Schedule is a
    multi-employer plan (within the meaning of Section 3(37) of ERISA).
 
        (D) With respect to each Plan, the Company has delivered to Parent: (i)
    an accurate and complete copy of such Plan (including all amendments
    thereto); (ii) an accurate and complete copy of the annual report, if
    required under ERISA, with respect to such Plan for the last two years;
    (iii) an accurate and complete copy of the most recent summary plan
    description, together with each Summary of Material Modifications, if
    required under ERISA, with respect to such Plan, (iv) if such Plan is funded
    through a trust or any third party funding vehicle, an accurate and complete
    copy of the trust or other funding agreement (including all amendments
    thereto) and accurate and complete copies the most recent financial
    statements thereof; (v) accurate and complete copies of all Contracts
    relating to such Plan, including service provider agreements, insurance

    treated as a single employer with any other Person under Section 4001(b)(1)
    of ERISA or Section 414(b), (c), (m) or (o) of the Code. None of the
    Acquired Corporations has ever been a member of an "affiliated service
    group" within the meaning of Section 414(m) of the Code. None of the
    Acquired Corporations has ever made a complete or partial withdrawal from a
    multi-employer plan, as such term is defined in Section 3(37) of ERISA,
    resulting in "withdrawal liability," as such term is defined in Section 4201
    of ERISA (without regard to subsequent reduction or waiver of such liability
    under either Section 4207 or 4208 of ERISA).
 
        (F) None of the Acquired Corporations has any plan or commitment to
    create any Welfare Plan or any additional Pension Plan, or to modify or
    change any existing Pension Plan (other than to comply with applicable law)
    in a manner that would affect any employee of any of the Acquired
    Corporations.

        (G) Except as set forth in Part 2.16(g) of the Company Disclosure
    Schedule, no Plan provides death, medical or health benefits (whether or not
    insured) with respect to any current or former employee of any of the
    Acquired Corporations after any such employee's termination of service
    (other than (i) benefit coverage mandated by applicable law, including
    coverage provided pursuant to Section 4980B of the Code, (ii) deferred
    compensation benefits accrued as liabilities on the Company Balance Sheet,
    and (iii) benefits the full cost of which are borne by current or former
    employees of any of the Acquired Corporations (or the employees'
    beneficiaries)).
 
        (H) With respect to any Plan constituting a group health plan within the
    meaning of Section 4980B(g)(2) of the Code, the provisions of Section 4980B
    of the Code ("COBRA") have been complied with in all material respects. Part
    2.16(h) of the Company Disclosure Schedule describes all obligations of the
    Acquired Corporations as of the date of this Agreement under any of the
    provisions of COBRA.
 
        (I) Each of the Plans has been operated and administered in all material
    respects in accordance with applicable Legal Requirements, including but not
    limited to ERISA and the Code.
 
        (J) Each of the Plans intended to be qualified under Section 401(a) of
    the Code has received a favorable determination from the Internal Revenue
    Service, and the Company is not aware of any reason why any such
    determination letter should be revoked.
 
        (K) Except as set forth in Part 2.16(k) of the Company Disclosure
    Schedule, neither the execution, delivery or performance of this Agreement,
    nor the consummation of the Merger or any of the other transactions
    contemplated by this Agreement, will result in any payment (including any
    bonus, golden parachute or severance payment) to any current or former
    employee or director of any of the Acquired Corporations (whether or not
    under any Plan), or materially increase the benefits payable under any Plan,
    or result in any acceleration of the time of payment or vesting of any such
    benefits.
 
        (L) Part 2.16(l) of the Company Disclosure Schedule contains a list of
    all salaried employees of each of the Acquired Corporations as of the date
    of this Agreement, and correctly reflects, in all material respects, their
    base salaries, their targeted annual bonus amounts, their dates of
    employment and their positions. None of the Acquired Corporations is a party
    to any collective bargaining contract or other Contract with a labor union
    involving any of its employees. All of the employees of the Acquired
    Corporations are "at will" employees.
 
        (M) Part 2.16(m) of the Company Disclosure Schedule identifies each
    Employee who is not fully available to perform work because of disability or
    other leave and sets forth the basis of such leave and the anticipated date
    of return to full service.
 
        (N) Each Plan complies in all material respects with all applicable
    Legal Requirements. Each of the Acquired Corporations is in compliance in
    all material respects with all Contracts relating to employment, employment
    practices, wages, bonuses and terms and conditions of employment, including
    employee compensation matters.
 
        (O) Except as set forth in Part 2.16(o) of the Company Disclosure
    Schedule, each of the Acquired Corporations has good labor relations, and
    none of the Acquired Corporations has any knowledge of any facts indicating
    that (i) the consummation of the Merger or any of the other transactions
    contemplated by this Agreement will have a material adverse effect on the
    labor relations of any of the Acquired Corporations, or (ii) any of the
    employees of the Acquired Corporations intends to terminate his or her
    employment with the Acquired Corporation with which such employee is
    employed.
 
    2.17  ENVIRONMENTAL MATTERS.  Each of the Acquired Corporations is in
compliance in all material respects with all applicable Environmental Laws,
which compliance includes the possession by each of the
 
                                       17
<PAGE>
Acquired Corporations of all permits and other Governmental Authorizations
required under applicable Environmental Laws, and compliance with the terms and
conditions thereof. None of the Acquired Corporations has received any notice or
other communication (in writing or otherwise), whether from a Governmental Body,
citizens group, employee or otherwise, that alleges that any of the Acquired
Corporations is not in compliance with any Environmental Law, and, to the best
of the knowledge of the Company, there are no circumstances that may prevent or
interfere with the compliance by any of the Acquired Corporations with any
Environmental Law in the future. To the best of the knowledge of the Company, no
current or prior owner of any property leased or controlled by any of the
Acquired Corporations has received any notice or other communication (in writing
or otherwise), whether from a Government Body, citizens group, employee or
otherwise, that alleges that such current or prior owner or any of the Acquired
Corporations is not in compliance with any Environmental Law. To the best of the
knowledge of the Company, all property that is leased to, controlled by or used
by the Company, and all surface water, groundwater and soil associated with or
adjacent to such property is in clean and healthful condition and is free of any
material environmental contamination of any nature. (For purposes of this
Section 2.17 and Section 3.13: (i) "ENVIRONMENTAL LAW" means any federal, state,
local or foreign Legal Requirement relating to pollution or protection of human
health or the environment (including ambient air, surface water, ground water,
land surface or subsurface strata), including any law or regulation relating to
emissions, discharges, releases or threatened releases of Materials of
Environmental Concern, or otherwise relating to the manufacture, processing,
distribution, use, treatment, storage, disposal, transport or handling of
Materials of Environmental Concern; and (ii) "MATERIALS OF ENVIRONMENTAL
CONCERN" include chemicals, pollutants, contaminants, wastes, toxic substances,
petroleum and petroleum products and any other substance that is now or
hereafter regulated by any Environmental Law or that is otherwise a danger to
health, reproduction or the environment.)
 
    2.18  INSURANCE.  The Company has delivered to Parent a copy of each
insurance policy and each self insurance program relating to the business,
assets or operations of any of the Acquired Corporations. Each such insurance
policy is in full force and effect. Since June 3, 1996, none of the Acquired
Corporations has received any notice or other communication regarding any actual
or possible (a) cancellation or invalidation of any insurance policy, (b)
refusal of any coverage or rejection of any material claim under any insurance
policy, or (c) material adjustment in the amount of the premiums payable with
respect to any insurance policy. Except as set forth in Part 2.18 of the Company
Disclosure Schedule, there is no pending claim (including any workers'
compensation claim) under or based upon any insurance policy of any of the
Acquired Corporations; and, to the best of the knowledge of the Company, no
event has occurred, and no condition or circumstance exists, that might (with or
without notice or lapse of time) directly or indirectly give rise to or serve as
a basis for any such claim.
 
    2.19  TRANSACTIONS WITH AFFILIATES.  Except as set forth in the Company SEC
Documents, since the date of the Company's last proxy statement filed with the
SEC, no event has occurred that would be required to be reported by the Company
pursuant to Item 404 of Regulation S-K promulgated by the SEC. Part 2.19 of the
Company Disclosure Schedule identifies each person who is an "affiliate" (as
that term is used in Rule 145 promulgated under the Securities Act) of the
Company as of the date of this Agreement.
 
    2.20  LEGAL PROCEEDINGS; ORDERS.
 
        (A) Except as set forth in Part 2.20(a) of the Company Disclosure
    Schedule, there is no pending Legal Proceeding (including, to the best
    knowledge of the Company, any investigation), and no Person has overtly
    threatened to commence any Legal Proceeding: (i) that involves any of the
    Acquired Corporations or any of the assets owned or used by any of the
    Acquired Corporations, including, without limitation, any Acquired Company
    Proprietary Asset; or (ii) that challenges, or that may have the effect of
    preventing, delaying, making illegal or otherwise interfering with, the
    Merger or any of the other transactions contemplated by this Agreement. To
    the best of the knowledge of the Company, no event has occurred, and no
    claim, dispute or other condition or circumstance exists, that will, or
 
                                       18
<PAGE>
    that could reasonably be expected to, give rise to or serve as a basis for
    the commencement of any such Legal Proceeding. To the best of the knowledge
    of the Company, no event has occurred, and no claim, dispute or other
    condition or circumstance exists, that will, or that could reasonably be
    expected to, cause or provide a basis for a director, officer or other
    Representative of any of the Acquired Corporations to seek indemnification
    from, or commence a Legal Proceeding against or involving, any of the
    Acquired Corporations.
 
        (B) There is no order, writ, injunction, judgment or decree to which any
    of the Acquired Corporations, or any of the assets owned or used by any of
    the Acquired Corporations, is subject. To the best of the knowledge of the
    Company, no officer or other employee of any of the Acquired Corporations is
    subject to any order, writ, injunction, judgment or decree that prohibits
    such officer or other employee from engaging in or continuing any conduct,
    activity or practice relating to the business of any of the Acquired
    Corporations.
 
    2.21  AUTHORITY; INAPPLICABILITY OF ANTI-TAKEOVER STATUTES; BINDING NATURE
OF AGREEMENT.  The Company has the absolute and unrestricted right, corporate
power and authority to enter into and to perform its obligations under this
Agreement. The Board of Directors of the Company (at a meeting duly called and
held) has (a) unanimously determined that the Merger is advisable and fair and
in the best interests of the Company and its shareholders, (b) unanimously
approved the execution, delivery and performance of this Agreement by the
Company and has unanimously approved the Merger, (c) unanimously recommended the
adoption and approval of this Agreement and the Merger by the holders of Company
Common Stock and directed that this Agreement and the Merger be submitted for
consideration by the Company's shareholders at the Company Shareholders' Meeting
(as defined in Section 5.2), and (d) approved, and the stockholders of the
Company have adopted, an amendment to the Company's Articles of Incorporation
having the effect of causing the Company not to be subject to any state takeover
law or similar Legal Requirement that might otherwise apply to the Merger or any
of the other transactions contemplated by this Agreement except as set forth in
Part 2.21 of the Company Disclosure Schedule. This Agreement constitutes the
legal, valid and binding obligation of the Company, enforceable against the
Company in accordance with its terms, subject to (i) laws of general application
relating to bankruptcy, insolvency and the relief of debtors, and (ii) rules of
law governing specific performance, injunctive relief and other equitable
remedies.
 
    2.22  NO EXISTING DISCUSSIONS.  None of the Acquired Corporations, and no
Representative of any of the Acquired Corporations, is engaged, directly or
indirectly, in any discussions or negotiations with any other Person relating to
any Acquisition Proposal.
 
    2.23  ACCOUNTING MATTERS.  To the best of the knowledge of the Company,
neither the Company nor any of its affiliates has taken or agreed to, or plans
to, take any action that would prevent Parent from accounting for the Merger as
a "pooling of interests."
 
    2.24  VOTE REQUIRED.  The affirmative vote of the holders of a majority of
the shares of Company Common Stock outstanding on the record date for the
Company Shareholder Meeting (the "REQUIRED COMPANY SHAREHOLDER VOTE") is the
only vote of the holders of any class or series of the Company's capital stock
necessary to adopt and approve this Agreement, the Merger and the other
transactions contemplated by this Agreement.
 
    2.25  NON-CONTRAVENTION; CONSENTS.  Neither (i) the execution, delivery or
performance of this Agreement or any of the other agreements referred to in this
Agreement, nor (ii) the consummation of the
 
                                       19
<PAGE>
Merger or any of the other transactions contemplated by this Agreement, will
directly or indirectly (with or without notice or lapse of time):
 
        (A) contravene, conflict with or result in a violation of (i) any of the
    provisions of the articles of incorporation, bylaws or other charter or
    organizational documents of any of the Acquired Corporations, or (ii) any
    resolution adopted by the shareholders, the board of directors or any
    committee of the board of directors of any of the Acquired Corporations;
 
        (B) contravene, conflict with or result in a violation of, or give any
    Governmental Body or other Person the right to challenge the Merger or any

    injunction, judgment or decree to which any of the Acquired Corporations, or
    any of the assets owned or used by any of the Acquired Corporations, is
    subject;
 
        (C) contravene, conflict with or result in a violation of any of the
    terms or requirements of, or give any Governmental Body the right to revoke,
    withdraw, suspend, cancel, terminate or modify, any Governmental
    Authorization that is held by any of the Acquired Corporations or that
    otherwise relates to the business of any of the Acquired Corporations or to
    any of the assets owned or used by any of the Acquired Corporations;
 
        (D) except as set forth in Part 2.25(d) of the Company Disclosure
    Schedule, contravene, conflict with or result in a violation or breach of,
    or result in a default under, any provision of any Acquired Corporation
    Contract that is or would constitute a Material Contract, or give any Person
    the right to (i) declare a default or exercise any remedy under any such
    Acquired Corporation Contract, (ii) a rebate, chargeback, penalty or change
    in delivery schedule under any such Acquired Corporation Contract, (iii)
    accelerate the maturity or performance of any such Acquired Corporation
    Contract, or (iv) cancel, terminate or modify any term of such Acquired
    Corporation Contract; or
 
        (E) result in the imposition or creation of any Encumbrance upon or with
    respect to any asset owned or used by any of the Acquired Corporations
    (except for minor liens that will not, in any case or in the aggregate,
    materially detract from the value of the assets subject thereto or
    materially impair the operations of any of the Acquired Corporations).
 
Except as may be required by the Exchange Act, the PBCL, the DGCL and the rules
of the National Association of Securities Dealers, Inc. ("NASD") (as they relate
to the S-4 Registration Statement and the Joint Proxy Statement/Prospectus, as
defined in Section 2.28(b)), none of the Acquired Corporations was, is or will
be required to make any filing with or give any notice to, or to obtain any
Consent from, any Person in connection with (x) the execution, delivery or
performance of this Agreement or any of the other agreements referred to in this
Agreement, or (y) the consummation of the Merger or any of the other
transactions contemplated by this Agreement.

written opinion of Robert W. Baird & Co. Incorporated, financial advisor to the
Company, dated the date of this Agreement, to the effect that the Exchange Ratio
is fair to the shareholders of the Company from a financial point of view. The
Company has furnished an accurate and complete copy of said written opinion to
Parent.
 
    2.27  FINANCIAL ADVISOR.  Except for Robert W. Baird & Co. Incorporated, no
broker, finder or investment banker is entitled to any brokerage, finder's or

Parent the fee formula pursuant to which fees, commissions and other amounts
will be paid by the Company to Robert W. Baird & Co. Incorporated if the Merger
is consummated. The Company has furnished to Parent accurate and complete copies
of all agreements under which any such fees, commissions or other amounts have

event that has had a Material Adverse Effect on Parent; (ii) Parent has not
declared, accrued, set aside or paid any dividend; and (iii) Parent has not
incurred any liabilities other than in the ordinary course of business and
consistent with past practices.
 
    3.6  AUTHORITY; BINDING NATURE OF AGREEMENT.  Parent and Merger Sub have the
absolute and unrestricted right, power and authority to perform their
obligations under this Agreement; and the execution, delivery and performance by
Parent and Merger Sub of this Agreement have been duly authorized by all
necessary action on the part of Parent and Merger Sub and their respective
boards of directors. This Agreement constitutes the legal, valid and binding
obligation of Parent and Merger Sub, enforceable against them in accordance with
its terms, subject to (i) laws of general application relating to bankruptcy,
insolvency and the relief of debtors, and (ii) rules of law governing specific
performance, injunctive relief and other equitable remedies.
 
    3.7  NON-CONTRAVENTION; CONSENTS.  Neither the execution and delivery of
this Agreement by Parent and Merger Sub nor the consummation by Parent and
Merger Sub of the Merger will (a) conflict with or result in any breach of any
provision of the certificate of incorporation or bylaws of Parent or the
articles of incorporation or bylaws of Merger Sub, or (b) result in a default by
Parent or Merger Sub under any Contract to which Parent or Merger Sub is a
party, except for any default which has not had and will not have a Material
Adverse Effect on Parent, or (c) result in a violation by Parent or Merger Sub
of any law, statute, rule, regulation, order, writ, injunction, judgment or
decree to which Parent or Merger Sub is subject, except for any violation which
has not had and will not have a Material Adverse Effect on Parent. Except as may
be required by the Securities Act, the Exchange Act, state securities or "blue
sky" laws, the PBCL, the DGCL and the rules of the NASD (as they relate to the
S-4 Registration Statement and the Joint Proxy Statement/Prospectus), Parent is
not and will not be required to make any filing with or give any notice to, or
to obtain any Consent from, any Person in connection with the execution and
delivery of this Agreement, or the consummation of the Merger.
 
    3.8  VOTE REQUIRED.  The only vote of Parent's stockholders required to
approve the issuance of Parent Common Stock in the Merger is the vote of a
majority of votes cast in person or by proxy as prescribed by rules of the NASD
(the "REQUIRED PARENT STOCKHOLDER VOTE").
 
    3.9  VALID ISSUANCE.  The Parent Common Stock to be issued in the Merger
will, when issued in accordance with the provisions of this Agreement, be duly
authorized, validly issued, fully paid and nonassessable.
 
    3.10  ACCOUNTING MATTERS.  To the best of the knowledge of Parent, Parent
has not taken and has not agreed, and does not plan, to take any action that
would prevent Parent from accounting for the Merger as a "pooling of interests."
 
    3.11  FAIRNESS OPINION.  Parent's Board of Directors has received the
written opinion of Hambrecht & Quist LLC, financial advisor to Parent, dated as
of the date of this Agreement, to the effect that
 
                                       23
<PAGE>
the Exchange Ratio is fair to Parent from a financial point of view. Parent has
furnished an accurate and complete copy of said written opinion to the Company.
 
    3.12  TAX MATTERS.
 
        (A) All Tax Returns required to be filed by or on behalf of the Parent
    and its Subsidiaries with any Governmental Body with respect to any taxable
    period ending on or before the Closing Date (the "PARENT RETURNS") (i) have
    been or will be filed on or before the applicable due date (including any
    extensions of such due date if properly obtained), and (ii) have been, or
    will be when filed, prepared in all material respects in compliance with all
    applicable Legal Requirements. All amounts shown on the Parent Returns to be
    due on or before the Closing Date have been or will be paid on or before the
    Closing Date.
 
        (B) The Parent financial statements in the Parent SEC Documents fully
    accrue all actual and contingent liabilities for Taxes with respect to all
    periods through the dates thereof in accordance with GAAP. Parent will
    establish, in the ordinary course of business and consistent with its past
    practices, reserves adequate for the payment of all Taxes for the period
    from the date of this Agreement through the Closing Date.
 
        (C) Since the Parent Return for the taxable period ended December 31,
    1992, no Parent Return has ever been examined or audited by any Governmental
    Body. No extension or waiver of the limitation period applicable to any of
    the Parent Returns has been granted (by Parent or any other Person), and no
    such extension or waiver has been requested from Parent or any of its
    Subsidiaries.
 
        (D) No claim or Legal Proceeding is pending or, to the best of the
    knowledge of the Parent, has been threatened against or with respect to
    Parent or any of its Subsidiaries in respect of any material Tax. There are
    no unsatisfied liabilities for material Taxes (including liabilities for
    interest, additions to tax and penalties thereon and related expenses) with
    respect to any notice of deficiency or similar document received by Parent
    or any of its Subsidiaries with respect to any material Tax (other than
    liabilities for Taxes asserted under any such notice of deficiency or
    similar document which are being contested in good faith by Parent or any of
    its Subsidiaries and with respect to which adequate reserves for payment
    have been established). There are no liens for material Taxes upon any of
    the assets of any of Parent or any of its Subsidiaries except liens for
    current Taxes not yet due and payable. Neither Parent nor any of its
    Subsidiaries has entered into or become bound by any agreement or consent
    pursuant to Section 341(f) of the Code. Neither Parent nor any of its
    Subsidiaries has been, and neither Parent nor any of its Subsidiaries will
    be, required to include any adjustment in taxable income for any tax period
    (or portion thereof) pursuant to Section 481 or 263A of the Code or any
    comparable provision under state or foreign Tax laws as a result of
    transactions or events occurring, or accounting methods employed, prior to
    the Closing.
 
        (E) There is no agreement, plan, arrangement or other Contract covering
    any employee or independent contractor or former employee or independent
    contractor of Parent or any of its Subsidiaries that, considered
    individually or considered collectively with any other such Contracts, will,
    or could reasonably be expected to, give rise directly or indirectly to the
    payment of any amount that would not be deductible pursuant to Section 280G
    or Section 162 of the Code. Neither Parent nor any of its Subsidiaries is,
    or has ever been, a party to or bound by any tax indemnity agreement, tax
    sharing agreement, tax allocation agreement or similar Contract.
 
    3.13  ENVIRONMENTAL MATTERS.  Except as set forth in Part 3.13 of the Parent
Disclosure Schedule, each of Parent and its Subsidiaries is in compliance in all
material respects with all applicable Environmental Laws, which compliance
includes the possession by each of Parent and its Subsidiaries of all permits
and other Governmental Authorizations required under applicable Environmental
Laws, and compliance with the terms and conditions thereof. Neither Parent nor
any of its Subsidiaries has received any notice or other communication (in
writing or otherwise), whether from a Governmental Body, citizens group,
 
                                       24
<PAGE>
employee or otherwise, that alleges that any of Parent or its Subsidiaries is
not in compliance with any Environmental Law, and, to the knowledge of Parent,
there are no circumstances that may prevent or interfere with the compliance by
Parent or any of its Subsidiaries with any Environmental Law in the future. To
the knowledge of the Parent, no current or prior owner of any property leased or
controlled by Parent or any of its Subsidiaries has received any notice or other
communication (in writing or otherwise), whether from a Government Body,
citizens group, employee or otherwise, that alleges that such current or prior
owner or Parent or any of its Subsidiaries is not in compliance with any
Environmental Law. To the knowledge of Parent, all property that is leased to,
controlled by or used by Parent, and all surface water, groundwater and soil
associated with or adjacent to such property is in clean and healthful condition
and is free of any material environmental contamination of any nature.
 
    3.14  SIGNIFICANT CUSTOMERS.  Part 3.14 of the Parent Disclosure Schedule
sets forth a complete and accurate list of all Parent's Significant Customers.
For purposes of this Agreement, "PARENT'S SIGNIFICANT CUSTOMERS" are the twenty
(20) customers of the Parent that have effected the most purchases, in dollar
terms, and accounted for the most revenues, in dollar terms, during the fiscal
year ended December 31, 1997. None of the Parent's Significant Customers has
canceled, returned or substantially reduced or, to the knowledge of the Parent,
is currently attempting or threatening to cancel, return or substantially
reduce, any purchases from, orders to or services provided by the Parent. Parent
has not received any material customer complaints concerning its products and/or
services.
 
    3.15  YEAR 2000 LIABILITIES.  Neither Parent nor any of its Subsidiaries has
any accrued, contingent or other liabilities of any nature, either matured or
unmatured, including, without limitation, any liabilities relating to costs
associated with insuring that all software (and related Parent Proprietary
Assets) that is sold, licensed or transferred by Parent or any of its
Subsidiaries to any Person, computer systems, any software utilized by the
Parent or other components of the Parent's information technology infrastructure
are Year 2000 Compliant (whether or not required to be reflected in financial
statements in accordance with GAAP, and whether due or to become due), except
for: (a) liabilities identified as such in the "liabilities" column of the
Parent Unaudited Interim Balance Sheet as of June 30, 1998 included in the
Parent's Quarterly Report on Form 10-Q for the quarter ended June 30, 1998; and
(b) normal and recurring liabilities that have been incurred by Parent since the
date of the Parent Unaudited Interim Balance Sheet in the ordinary course of
business and consistent with past practices.

    shall
 
                                       28
<PAGE>
    not prohibit the Company from furnishing nonpublic information regarding the
    Acquired Corporations to, or entering into discussions with, any Person in
    response to a Superior Offer submitted by such Person (and not withdrawn) if
    (1) neither the Company nor any Representative of any of the Acquired
    Corporations shall have violated any of the restrictions set forth in this
    Section 4.3, (2) the Board of Directors of the Company concludes in good
    faith, based upon the advice of its outside legal counsel, that such action

    to furnish nonpublic information to, or enter into discussions with, such
    Person, and the Company receives from such Person an executed
    confidentiality agreement containing customary limitations on the use and
    disclosure of all nonpublic written and oral information furnished to such
    Person by or on behalf of the Company, and (4) prior to furnishing any such
    nonpublic information to such Person, the Company furnishes such nonpublic

    violation of any of the restrictions set forth in the preceding sentence by

    Representative is purporting to act on behalf of any of the Acquired
    Corporations, shall be deemed to constitute a breach of this Section 4.3 by
    the Company. In addition to the foregoing, the Company shall (i) provide

    S-4 Registration Statement declared effective under the Securities Act as
    promptly as practicable after it is filed with the SEC. Parent will use all
    reasonable efforts to cause the Joint Proxy Statement/ Prospectus to be
    mailed to Parent's stockholders and the Company will use all reasonable
    efforts to cause the Joint Proxy Statement/Prospectus to be mailed to the
    Company's shareholders, as promptly as practicable after the Form S-4
    Registration Statement is declared effective under the Securities Act. The
    Company shall promptly furnish to Parent all information concerning the
    Acquired Corporations and the Company's shareholders that may be required or
    reasonably requested in connection with any action contemplated by this
    Section 5.1. If any event relating to any of the Acquired Corporations
    occurs, or if the Company becomes aware of any information, that should be
    set forth in an amendment or supplement to the S-4 Registration Statement or
    the Joint Proxy Statement/Prospectus, then the Company shall promptly inform
    Parent thereof and shall cooperate with Parent in filing such amendment or
    supplement with the SEC and, if appropriate, in mailing such amendment or
    supplement to the shareholders of the Company and the stockholders of
    Parent.
 
        (B) Prior to the Effective Time, Parent shall use reasonable efforts to
    obtain all regulatory approvals needed to ensure that the Parent Common

    securities law of every jurisdiction of the United States in which any
    registered holder of Company Common Stock has an address of record on the
    record date for determining the shareholders entitled to notice of and to
    vote at the Company Shareholders' Meeting; PROVIDED, HOWEVER, that Parent
    shall not be required (i) to qualify to do business as a foreign corporation
    in any jurisdiction in which it is not now qualified or (ii) to file a
    general consent to service of process in any jurisdiction.
 
    5.2  COMPANY SHAREHOLDERS' MEETING.
 
        (A) The Company shall take all action necessary under all applicable
    Legal Requirements to call, give notice of, convene and hold a meeting of
    the holders of Company Common Stock (the "COMPANY SHAREHOLDERS' MEETING") to
    consider, act upon and vote upon the adoption of this Agreement and approval
    of the Merger. The Company Shareholders' Meeting will be held as promptly as
    practicable and in any event within forty-five (45) days after the S-4
    Registration Statement is declared effective under the Securities Act;
    PROVIDED, HOWEVER, that notwithstanding anything to the contrary contained
    in this Agreement, the Company may adjourn or postpone the Company
    Shareholders' Meeting to the extent necessary to ensure that any necessary
    supplement or amendment to the Joint Proxy Statement/ Prospectus is provided
    to the Company's shareholders in advance of a vote on the Merger and this
    Agreement or, if as of the time for which Company Shareholders' Meeting is
    originally scheduled (as set forth in the Joint Proxy Statement/Prospectus)
    there are insufficient shares of Company Common Stock represented (either in
    person or by proxy) to constitute a quorum necessary to conduct the business
    of the Company's Shareholders' Meeting. The Company shall ensure that the
    Company Shareholders' Meeting is called, noticed, convened, held and
    conducted, and that all proxies solicited in connection with the Company
    Shareholders' Meeting are solicited, in compliance with all applicable Legal
    Requirements. The Company's obligation to call, give notice of, convene and
    hold the Company Shareholders' Meeting in accordance with this Section
    5.2(a) shall not be limited or otherwise affected by the commencement,
    disclosure, announcement or submission to the Company of any Acquisition
    Proposal, or by any withdrawal, amendment or modification of the
    recommendation of the Board of Directors of the Company with respect to the
    Merger.
 
        (B) Subject to Section 5.2(c): (i) the Board of Directors of the Company
    shall unanimously recommend that the Company's shareholders vote in favor of
    and adopt and approve this Agreement and the Merger at the Company
    Shareholders' Meeting; (ii) the Joint Proxy Statement/Prospectus shall
    include a statement to the effect that the Board of Directors of the Company
    has unanimously recommended that the Company's shareholders vote in favor of
    and adopt and approve this Agreement and the Merger at the Company
    Shareholders' Meeting; and (iii) neither the Board of Directors of the
    Company nor any committee thereof shall withdraw, amend or modify, or
    propose or resolve to
 
                                       30
<PAGE>
withdraw, amend or modify, in a manner adverse to Parent, the unanimous
recommendation of the Board of Directors of the Company that the Company's
shareholders vote in favor of and adopt and approve this Agreement and the
Merger. For purposes of this Agreement, said recommendation of the Board of
Directors shall be deemed to have been modified in a manner adverse to Parent if
said recommendation shall no longer be unanimous.
 
        (C) Nothing in Section 5.2(b) shall prevent the Board of Directors of
    the Company from withdrawing, amending or modifying its unanimous
    recommendation in favor of the Merger if (i) a Superior Offer is made to the
    Company and is not withdrawn, (ii) neither the Company nor any of its
    Representatives shall have violated any of the restrictions set forth in
    Section 4.3, and (iii) the Board of Directors of the Company concludes in
    good faith, based upon the advice of its outside counsel, that, in light of
    such Superior Offer, the withdrawal, amendment or modification of such
    recommendation is required in order for the Board of Directors of the
    Company to comply with its fiduciary obligations to the Company's
    shareholders under applicable law. Nothing contained in this Section 5.2
    shall limit the Company's obligation to hold and convene the Company
    Shareholders' Meeting (regardless of whether the unanimous recommendation of
    the Board of Directors of the Company shall have been withdrawn, amended or
    modified).
 
    5.3  PARENT STOCKHOLDERS' MEETING.
 
        (A) Parent shall take all action necessary to call, give notice of,
    convene and hold a meeting of the holders of Parent Common Stock to consider
    and vote upon the issuance of Parent Common Stock in the Merger (the "PARENT
    STOCKHOLDERS' MEETING"). The Parent Stockholders' Meeting will be held as
    promptly as practicable and in any event within forty-five (45) days after
    the S-4 Registration Statement is declared effective under the Securities
    Act; PROVIDED, HOWEVER, that notwithstanding anything to the contrary
    contained in this Agreement, Parent may adjourn or postpone the Parent
    Stockholders' Meeting to the extent necessary to ensure that any necessary
    supplement or amendment to the Joint Proxy Statement/Prospectus is provided
    to Parent's stockholders in advance of a vote on the issuance of Parent
    Common Stock in the Merger or, if as of the time for which the Parent
    Stockholders' Meeting is originally scheduled (as set forth in the Joint
    Proxy Statement/Prospectus) there are insufficient shares of Parent Common
    Stock represented (either in person or by proxy) to constitute a quorum
    necessary to conduct the business of the Parent's Stockholders' Meeting.
 
        (B) (i) The board of directors of Parent shall unanimously recommend
    that Parent's stockholders vote in favor of the issuance of Parent Common
    Stock in the Merger; (ii) the Joint Proxy Statement/ Prospectus shall

    unanimously recommended that Parent's stockholders vote in favor of the
    issuance of Parent Common Stock in the Merger; and (iii) neither the board
    of directors of Parent nor any committee thereof shall withdraw, amend or
    modify, or propose or resolve to withdraw, amend or modify, in a manner
    adverse to the Company, the unanimous recommendation of the board of
    directors of Parent that Parent's stockholders vote in favor of the issuance
    of Parent Common Stock in the Merger. For purposes of this Agreement, said
    recommendation of Parent's board of directors shall be deemed to have been
    modified in a manner adverse to the Company if said recommendation shall no
    longer be unanimous.
 
    5.4  REGULATORY APPROVALS.  The Company and Parent shall use all reasonable
efforts to file, as soon as practicable after the date of this Agreement, all
notices, reports and other documents required to be filed with any Governmental
Body with respect to the Merger and the other transactions contemplated by this
Agreement, and to submit promptly any additional information requested by any
such Governmental Body. The Company and Parent shall respond as promptly as
practicable to any inquiries or requests received from any state attorney
general or other Governmental Body in connection with antitrust or related
matters. Each of the Company and Parent shall (1) give the other party prompt

Body with respect to the Merger or any of the other transactions contemplated by
this Agreement, (2) keep the other party informed as to
 
                                       31

the status of any such Legal Proceeding, and (3) promptly inform the other party
of any communication to or from the Federal Trade Commission, the Department of
Justice or any other Governmental Body regarding the Merger. The Company and
Parent will consult and cooperate with one another, and will consider in good
faith the views of one another, in connection with any analysis, appearance,
presentation, memorandum, brief, argument, opinion or proposal made or submitted
in connection with any Legal Proceeding under or any other federal or state
antitrust or fair trade law. In addition, except as may be prohibited by any
Governmental Body or by any Legal Requirement, in connection with any Legal
Proceeding under or any other federal or state antitrust or fair trade law or
any other similar Legal Proceeding, each of the Company and Parent agrees to
permit authorized Representatives of the other party to be present at each
meeting or conference relating to any such Legal Proceeding and to have access
to and be consulted in connection with any document, opinion or proposal made or
submitted to any Governmental Body in connection with any such Legal Proceeding.

    dividend, reverse stock split, reclassification, recapitalization or other

    plans pursuant to which Company Options are outstanding and otherwise) to

<PAGE>
number of shares of Parent Common Stock subject to each Company Warrant shall be
equal to the number of shares of Company Common Stock subject to such Company
Warrant immediately prior to the Effective Time multiplied by the Exchange
Ratio, rounding down to the nearest whole share (with cash, less the applicable
exercise price, being payable for any fraction of a share), (c) the per share
exercise price under each such Company Warrant shall be adjusted by dividing the
per share exercise price under such Company Warrant by the Exchange Ratio and
rounding up to the nearest cent and (d) any restriction on the exercise of any
Company Warrant shall continue in full force and effect and the term,
exercisability, schedule and other provisions of such Company Warrant shall
otherwise remain unchanged; PROVIDED, HOWEVER, that such Company Warrant shall,

        (B) by either Parent or the Company if the Merger shall not have been
    consummated by January 31, 1999 (unless the failure to consummate the Merger

    by such party at or prior to the Effective Time);
 
        (C) by either Parent or the Company if a court of competent jurisdiction

    adopted and approved at such meeting by the Company Required Shareholder
    Vote (PROVIDED that the right to terminate this Agreement under this Section

    Required Stockholder Vote;
 
        (G) by Parent if any of the Company's representations and warranties
    contained in this Agreement shall be or shall have become materially
    inaccurate, or if any of the Company's covenants contained in this Agreement
    shall have been breached in any material respect; PROVIDED, HOWEVER, that if
    an inaccuracy in the Company's representations and warranties or a breach of
    a covenant by the Company is curable by the Company and the Company is
    continuing to exercise all reasonable efforts to cure such inaccuracy or
    breach, then Parent may not terminate this Agreement under this Section
    8.1(g) on account of such inaccuracy or breach; or
 
        (H) by the Company if any of Parent's representations and warranties
    contained in this Agreement shall be or shall have become materially
    inaccurate, or if any of Parent's covenants contained in this Agreement
    shall have been breached in any material respect; PROVIDED, HOWEVER, that if
    an inaccuracy in Parent's representations and warranties or a breach of a
    covenant by Parent is curable by Parent and Parent is continuing to exercise
    all reasonable efforts to cure such inaccuracy or breach, then the Company
    may not terminate this Agreement under this Section 8.1(h) on account of
    such inaccuracy or breach.
 
    8.2  NOTICE OF TERMINATION; EFFECT OF TERMINATION.  Any termination under
Section 8.1 above will be effective immediately upon the delivery of written
notice of the terminating party to the other parties hereto. In the event of the

shall remain in full force and effect, (ii) the termination of this Agreement
shall not relieve any party from any liability for any breach of this Agreement

    8.3  EXPENSES; TERMINATION FEES.
 
        (A) Except as set forth in this Section 8.3, all fees and expenses
    incurred in connection with this Agreement and the transactions contemplated
    by this Agreement shall be paid by the party incurring such expenses,
    whether or not the Merger is consummated; PROVIDED, HOWEVER, that Parent and
    the Company shall share equally all fees and expenses, other than attorneys'
    fees, incurred in connection with the printing and filing of the S-4
    Registration Statement and the Joint Proxy Statement/ Prospectus and any
    amendments or supplements thereto.

    7.14  WAIVER.  No failure on the part of Parent to exercise any power,
right, privilege or remedy under this Agreement, and no delay on the part of

    The undersigned stockholder of INTEGRATED SYSTEMS CONSULTING GROUP, INC., a
Pennsylvania corporation (the "COMPANY"), hereby irrevocably (to the fullest
extent permitted by law) appoints and constitutes James A. Reep, Luther J.
Nussbaum and Thomas A. Reep, and First Consulting Group, Inc., a Delaware
corporation ("Parent"), and each of them, the attorneys and proxies of the
undersigned with full power of substitution and resubstitution, to the full
extent of the undersigned's rights with respect to (i) the outstanding shares of
capital stock of the Company owned of record by the undersigned as of the date
of this proxy, which shares are specified on the final page of this proxy, and
(ii) any and all other shares of capital stock of the Company which the
undersigned may acquire on or after the date hereof. (The shares of the capital
stock of the Company referred to in clauses "(i)" and "(ii)" of the immediately
preceding sentence are collectively referred to as the "SHARES.") Upon the
execution hereof, all prior proxies given by the undersigned with respect to any
of the Shares are hereby revoked, and the undersigned agrees that no subsequent
proxies will be given with respect to any of the Shares.
 
    This proxy is irrevocable, is coupled with an interest and is granted in
connection with the Voting Agreement, dated as of the date hereof, between
Parent and the undersigned (the "VOTING AGREEMENT"), and is granted in
consideration of Parent entering into the Agreement and Plan of Merger and
Reorganization, dated as of the date hereof, among Parent, Foxtrot Acquisition
Sub, Inc. and the Company (the "MERGER AGREEMENT").
 
    The attorneys and proxies named above will be empowered, and may exercise
this proxy, to vote the Shares at any time until the earlier to occur of the
valid termination of the Merger Agreement or the effective time of the merger
contemplated thereby (the "MERGER") at any meeting of the stockholders of the
Company, however called, or in connection with any solicitation of written
consents from stockholders of the Company, in favor of the approval and adoption
of the Merger Agreement and the approval of the Merger, and in favor of each of
the other actions contemplated by the Merger Agreement.
 
    The undersigned may vote the Shares on all other matters.
 
    This proxy shall be binding upon the heirs, estate, executors, personal
representatives, successors and assigns of the undersigned (including any
transferee of any of the Shares).
 
    If any provision of this proxy or any part of any such provision is held
under any circumstances to be invalid or unenforceable in any jurisdiction, then
(a) such provision or part thereof shall, with respect to such circumstances and
in such jurisdiction, be deemed amended to conform to applicable laws so as to
be valid and enforceable to the fullest possible extent, (b) the invalidity or
unenforceability of such provision or part thereof under such circumstances and
in such jurisdiction shall not affect the validity or enforceability of such
provision or part thereof under any other circumstances or in any other
jurisdiction, and (c) the invalidity or unenforceability of such provision or
part thereof shall not affect the validity or enforceability of the remainder of
such provision or the validity or enforceability of any other provision of this
proxy. Each provision of this proxy is separable from every other provision of
this proxy, and each part of each provision of this proxy is separable from
every other part of such provision.

between the parties with respect to the subject matter hereof and thereof and
supersede all prior agreements and understandings between the parties with
respect thereto.
 
    5.7  ASSIGNMENT; BINDING EFFECT.  Except as provided herein, neither this
Agreement nor any of the interests or obligations hereunder may be assigned or
delegated by Stockholder and any attempted or purported assignment or delegation
of any of such interests or obligations shall be void. Subject to the preceding

right, privilege or remedy under this Agreement, and no delay on the part of
Company in exercising any power, right, privilege or remedy under this
Agreement, shall operate as a waiver of such power, right, privilege or remedy;

                           FORM OF IRREVOCABLE PROXY
 
    The undersigned stockholder of FIRST CONSULTING GROUP, INC. a Delaware
corporation ("PARENT"), hereby irrevocably (to the fullest extent permitted by
law) appoints and constitutes David S. Lipson, and Integrated Systems Consulting
Group, Inc., a Pennsylvania corporation (the "COMPANY"), and each of them, the

resubstitution, to the full extent of the undersigned's rights with respect to
(i) the outstanding shares of capital stock of Parent owned of record by the
undersigned as of the date of this proxy, which shares are specified on the
final page of this proxy, and (ii) any and all other shares of capital stock of
Parent which the undersigned may acquire on or after the date hereof. (The
shares of the capital stock of Parent referred to in clauses "(i)" and "(ii)" of
the immediately preceding sentence are collectively referred to as the
"SHARES.") Upon the execution hereof, all prior proxies given by the undersigned
with respect to any of the Shares are hereby revoked, and the undersigned agrees
that no subsequent proxies will be given with respect to any of the Shares.
 
    This proxy is irrevocable, is coupled with an interest and is granted in
connection with the Voting Agreement, dated as of the date hereof, between the
Company and the undersigned (the "VOTING AGREEMENT"), and is granted in
consideration of the Company entering into the Agreement and Plan of Merger and
Reorganization, dated as of the date hereof, among Parent, Foxtrot Acquisition
Sub, Inc. and the Company (the "MERGER AGREEMENT").
 
    The attorneys and proxies named above will be empowered, and may exercise
this proxy, to vote the Shares at any time until the earlier to occur of the
valid termination of the Merger Agreement or the effective time of the merger
contemplated thereby (the "MERGER") at any meeting of the stockholders of
Parent, however called, or in connection with any solicitation of written
consents from stockholders of Parent, in favor of the approval and adoption of
the Merger Agreement and the approval of the Merger, and in favor of each of the
other actions contemplated by the Merger Agreement.
 
    The undersigned may vote the Shares on all other matters.
 
    This proxy shall be binding upon the heirs, estate, executors, personal
representatives, successors and assigns of the undersigned (including any
transferee of any of the Shares).
 
    If any provision of this proxy or any part of any such provision is held
under any circumstances to be invalid or unenforceable in any jurisdiction, then
(a) such provision or part thereof shall, with respect to such circumstances and
in such jurisdiction, be deemed amended to conform to applicable laws so as to
be valid and enforceable to the fullest possible extent, (b) the invalidity or
unenforceability of such provision or part thereof under such circumstances and
in such jurisdiction shall not affect the validity or enforceability of such
provision or part thereof under any other circumstances or in any other
jurisdiction, and (c) the invalidity or unenforceability of such provision or
part thereof shall not affect the validity or enforceability of the remainder of
such provision or the validity or enforceability of any other provision of this
proxy. Each provision of this proxy is separable from every other provision of
this proxy, and each part of each provision of this proxy is separable from
every other part of such provision.
 
    This proxy shall terminate upon the earlier of the valid termination of the
Merger Agreement or the effective time of the Merger.

                          COMPANY AFFILIATE AGREEMENT
 
    THIS COMPANY AFFILIATE AGREEMENT (this "AGREEMENT") is dated as of September
9, 1998, by and between FIRST CONSULTING GROUP, INC., a Delaware corporation
("PARENT"), INTEGRATED SYSTEMS CONSULTING GROUP, INC., a Pennsylvania
corporation ("COMPANY"), and the undersigned affiliate ("AFFILIATE").
 
                                    RECITALS
 
    WHEREAS, Affiliate is a stockholder of Company.
 
    WHEREAS, Parent, Foxtrot Acquisition Sub, Inc., a Delaware corporation and a
wholly-owned subsidiary of Parent ("MERGER SUB"), and Company have entered into
an Agreement and Plan of Merger and Reorganization dated as of September 9, 1998
(the "MERGER AGREEMENT"), providing for the merger of Merger Sub with and into
Company (the "MERGER"). The Merger Agreement contemplates that, upon
consummation of the Merger, (i) the holders of the common stock of Company
("COMPANY COMMON STOCK") will receive shares of common stock of Parent ("PARENT
COMMON STOCK") in exchange for their shares of Company Common Stock and (ii)
Company will become a wholly-owned subsidiary of Parent. It is accordingly
contemplated that Affiliate will receive shares of Parent Common Stock in the
Merger.
 
    WHEREAS, Affiliate understands that the Parent Common Stock being issued in
the Merger will be issued pursuant to a registration statement on Form S-4 and
that Affiliate may be deemed to be an "affiliate" of Company, as the term
"affiliate" is used (i) for purposes of paragraphs (c) and (d) of Rule 145
("RULE 145") of the General Rules and Regulations of the Securities and Exchange
Commission (the "SEC") under the Securities Act of 1933, as amended (the
"SECURITIES ACT"), and (ii) in the SEC's Accounting Series Releases 130 and 135,
and, as such, Affiliate may only transfer, sell or dispose of such Parent Common
Stock in accordance with this Affiliate Agreement and Rule 145.
 
    WHEREAS, it is a condition to the consummation of the Merger pursuant to the
Merger Agreement that the independent accounting firms that audit the annual
financial statements of Parent and Company will have delivered the written
concurrences with the conclusions of management of Parent and Company to the
effect that the Merger will be accounted for as a pooling of interests under
Accounting Principles Board Opinion No. 16.
 
                                   AGREEMENT
 
    NOW, THEREFORE, in order to induce Parent and Company to consummate the
transactions contemplated by the Merger Agreement, and for other valuable
consideration (the receipt and sufficiency of which are hereby acknowledged by
Affiliate), Affiliate hereby covenants and agrees as follows:
 
    1.  REPRESENTATIONS AND WARRANTIES.  Affiliate represents and warrants to
Parent as follows:
 
        (A) Affiliate is the holder and "beneficial owner" (as defined in Rule
    13d-3 under the Securities Exchange Act of 1934, as amended) of the number
    of shares of Company Common Stock set forth under Affiliate's signature
    below (the "COMPANY SHARES"), and Affiliate has good and valid title to
    Company Shares, free and clear of any liens, pledges, security interests,
    adverse claims, equities, options, proxies, charges, encumbrances or
    restrictions of any nature.
 
        (B) Affiliate has carefully read this Agreement, and has discussed with
    Affiliate's own independent counsel to the extent Affiliate felt necessary
    the limitations imposed on Affiliate's ability to sell, transfer or
    otherwise dispose of the shares of Parent Common Stock that Affiliate is to
    receive in the Merger (the "PARENT SHARES"). Affiliate fully understands the
    limitations this Agreement places upon Affiliate's ability to sell, transfer
    or otherwise dispose of the Parent Shares.
 
        (C) Affiliate understands that the representations, warranties and
    covenants set forth herein will be relied upon by Parent, Company, and their
    respective affiliates, counsel and accounting firms for
 
                                       1
<PAGE>
    purposes of determining Parent's eligibility to account for the Merger as a
    "pooling of interests," and that substantial losses and damages may be
    incurred by these persons if Affiliate's representations, warranties or
    covenants are breached.
 
    2.  PROHIBITION AGAINST TRANSFER.  In addition to the restrictions set forth
elsewhere herein, Affiliate agrees that Affiliate shall not effect any sale,
transfer or other disposition of the Parent Shares unless:
 
        (A) such sale, transfer or other disposition is made in conformity with
    the volume and other requirements of Rule 145 under the Securities Act, as
    evidenced by a broker's letter and a representation letter executed by
    Affiliate (reasonably satisfactory in form and content to Parent), each
    stating that such requirements have been met;
 
        (B) counsel reasonably satisfactory to Parent shall have advised Parent
    in a written opinion letter (reasonably satisfactory in form and content to
    Parent), upon which Parent may rely, that such sale, transfer or other
    disposition will be exempt from registration under the Securities Act;
 
        (C) such sale, transfer or other disposition is effected pursuant to an
    effective registration statement under the Securities Act; or
 
        (D) an authorized representative of the SEC shall have rendered written
    advice to Affiliate to the effect that the SEC would take no action, or that
    the staff of the SEC would not recommend that the SEC take action, with
    respect to such proposed sale, transfer or other disposition, and a copy of
    such written advice and all other related communications with the SEC shall
    have been delivered to Parent.
 
    3.  STOP TRANSFER INSTRUCTIONS; LEGEND.  Affiliate acknowledges and agrees
that (a) stop transfer instructions will be given to Parent's transfer agent
with respect to the Parent Shares, and (b) each certificate representing any of
such shares of Parent Common Stock or any substitutions thereof shall bear a
legend (together with any other legend or legends required by applicable state
securities laws or otherwise), stating in substance:
 
       THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED IN A
       TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT
       OF 1933 APPLIES. THE SHARES REPRESENTED BY THIS CERTIFICATE MAY
       NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, ASSIGNED, PLEDGED
       OR HYPOTHECATED EXCEPT IN ACCORDANCE WITH THE PROVISIONS OF SUCH
       RULE AND IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT DATED AS OF
       SEPTEMBER 9, 1998, BETWEEN THE REGISTERED HOLDER FIRST CONSULTING
       GROUP, INC., A COPY OF WHICH AGREEMENT IS ON FILE AT THE PRINCIPAL
       OFFICES OF FIRST CONSULTING GROUP, INC.
 
    4.  COVENANTS RELATED TO POOLING OF INTERESTS.  In accordance with SEC Staff
Accounting Bulletin No. 65 ("SAB 65"), during the period contemplated by SAB 65,
until the earlier of (i) Parent's public announcement of financial results
covering at least 30 days of combined operations of Parent and Company or (ii)
the Merger Agreement is terminated in accordance with its terms, Affiliate will
not sell, exchange, transfer, pledge, distribute, or otherwise dispose of or
grant any option, establish any "short" or put-equivalent position with respect
to or enter into any similar transaction (through derivatives or otherwise)
intended or having the effect, directly or indirectly, to reduce its risk
relative to: (i) any shares of Company Common Stock, except pursuant to and upon
the consummation of the Merger; or (ii) any shares of Parent Common Stock
received by Affiliate in the Merger or any shares of Parent Common Stock
received by Affiliate upon exercise of options assumed by Parent in connection
with the Merger. Parent may, at its discretion, cause a restrictive legend
covering the restrictions referred to in this Section 4 to be placed on Parent
Common Stock certificates issued to Affiliate in the Merger and place a stock
transfer notice consistent with the restrictions referred to in this Section 4
with its transfer agent with
 
                                       2
<PAGE>
respect to such certificates, provided such restrictive legend shall be removed
and/or notice shall be countermanded promptly upon expiration of the necessity
therefor at the request of Affiliate.
 
    5.  PERMITTED TRANSFERS.  Notwithstanding anything to the contrary contained
in this Agreement, Affiliate (i) may transfer Affiliate's PRO RATA portion (of
the total number of shares available under the "de minimis" exception referred
to in this clause (i) to all affiliates of Parent and Company) of the "de
minimis" number of shares of Company Common Stock and Parent Common Stock
available for sale in accordance with SEC Staff Accounting Bulletin No. 76 (the
"DE MINIMIS POOL") contingent upon confirmation and approval by legal counsel
for Company and independent auditors to Company and Parent that such transfer
qualifies as within Affiliate's pro rata portion of the De Minimis Pool and does
not otherwise adversely affect the Parent's ability to account for the Merger as
a "pooling of interests" (ii) may (with the written consent of Parent, not to be
unreasonably withheld): (A) transfer shares of Company Common Stock or Parent
Common Stock to Company in payment of the exercise price of options to purchase
Company Common Stock; (B) transfer shares of Parent Common Stock in payment of
the exercise price of options to purchase Parent Common Stock; (C) transfer
shares of Company Common Stock or Parent Common Stock to any organization
qualified under Section 501(c)(3) of the Internal Revenue Code of 1986, as
amended, so long as such organization has traditionally been supported by
contributions from the general public (as opposed to being supported largely by
a specific donor); and (D) transfer shares of Company Common Stock or shares of
Parent Common Stock to a trust established for the benefit of Affiliate and/or
for the benefit of one or more members of Affiliate's family, or make a bona
fide gift of shares of Common Stock of Company or shares of Parent Common Stock
to one or more members of Affiliate's family, provided that in the case of a
transfer or gift pursuant to this clause (C) or (D), a transferee of such shares
agrees to be bound by the limitations set forth in this Agreement.
 
    6.  SPECIFIC PERFORMANCE.  The parties agree that irreparable damage would
occur in the event that any of the provisions of this Agreement was not
performed in accordance with its specific terms or was otherwise breached.
Affiliate agrees that, in the event of any breach or threatened breach by
Affiliate of any covenant or obligation contained in this Agreement, each of
Parent and Company shall be entitled (in addition to any other remedy that may
be available to it, including monetary damages) to seek and obtain (a) a decree
or order of specific performance to enforce the observance and performance of
such covenant or obligation, and (b) an injunction restraining such breach or
threatened breach.
 
    7.  INDEPENDENCE OF OBLIGATIONS.  The covenants and obligations of Affiliate
set forth in this Affiliate Agreement shall be construed as independent of any
other agreement or arrangement between Affiliate, on the one hand, and Company
or Parent, on the other. The existence of any claim or cause of action by
Affiliate against Company or Parent shall not constitute a defense to the
enforcement of any of such covenants or obligations against Affiliate.
 
    8.  NOTICES.  Any notice or other communication required or permitted to be
delivered under this Agreement shall be in writing and shall be deemed properly
delivered, given and received when delivered (by hand, by registered mail, by
courier or express delivery service or by facsimile confirmation) to the address
or facsimile telephone number set forth beneath the name of such party below (or
to such other address or facsimile telephone number as such party shall have

such circumstances and in such jurisdiction, be deemed amended to conform to
applicable laws so as to be valid and enforceable to the fullest possible
extent, (b) the invalidity or unenforceability of such provision or part thereof
under such circumstances and in such jurisdiction shall not affect the validity

power, right, privilege or remedy under this Agreement, and no delay on the part
of Parent or Company in exercising any power, right, privilege or remedy under
this Agreement, shall operate as a waiver of such power, right, privilege or
remedy; and no single or partial exercise of any such power, right, privilege or
remedy shall preclude any
 
                                       4
<PAGE>
other or further exercise thereof or of any other power, right, privilege or
remedy. Neither Parent or Company shall be deemed to have waived any claim
arising out of this Agreement, or any power, right, privilege or remedy under
this Agreement, unless the waiver of such claim, power, right, privilege or
remedy is expressly set forth in a written instrument duly executed and
delivered on behalf of the party deemed to be charged; and any such waiver shall
not be applicable or have any effect except in the specific instance in which it
is given.

hereunder are not exclusive of or limited by any other rights or remedies which
Parent may have, whether at law, in equity, by contract or otherwise, all of
which shall be cumulative (and not alternative). Nothing in this Agreement shall

Company, under any Voting Agreement (including any Irrevocable Proxy contained

Agreement shall limit any of Affiliate's obligations, or any of the rights or
remedies of Parent, under this Agreement.

obligations contained in this Agreement shall survive the consummation of the

                           PARENT AFFILIATE AGREEMENT
 
    THIS PARENT AFFILIATE AGREEMENT (this "AGREEMENT") is dated as of September
9, 1998, by and between FIRST CONSULTING GROUP, INC., a Delaware corporation
("PARENT"), INTEGRATED SYSTEMS CONSULTING GROUP, INC., a Pennsylvania
corporation (the "COMPANY"), and the undersigned affiliate of Parent
("AFFILIATE").
 
                                    RECITALS
 
    WHEREAS, Affiliate is a stockholder of Parent.
 
    WHEREAS, Parent, Foxtrot Acquisition Sub, Inc., a Delaware corporation and a
wholly-owned subsidiary of Parent ("MERGER SUB"), and the Company have entered
into an Agreement and Plan of Merger and Reorganization dated as of September 9,
1998 (the "MERGER AGREEMENT"), providing for the merger of Merger Sub with and
into the Company (the "MERGER"). The Merger Agreement contemplates that, upon
consummation of the Merger, (i) the holders of the common stock of the Company
("COMPANY COMMON STOCK") will receive shares of common stock of Parent ("PARENT
COMMON STOCK") in exchange for their shares of Company Common Stock and (ii) the
Company will become a wholly-owned subsidiary of Parent.
 
    WHEREAS, pursuant to the Merger Agreement it is a condition to consummation
of the Merger that Parent register shares of Parent Common Stock issued to
certain stockholders of the Company in connection with the Merger pursuant to
the terms of a Registration Rights Agreement in the form of Exhibit I to the
Merger Agreement.
 
    WHEREAS, it is a condition to the consummation of the Merger pursuant to the
Merger Agreement that the independent accounting firms that audit the annual
financial statements of Parent and the Company will have delivered the written
concurrences with the conclusions of management of Parent and the Company to the
effect that the Merger will be accounted for as a pooling of interests under
Accounting Principles Board Opinion No. 16.
 
                                   AGREEMENT
 
    NOW, THEREFORE, in order to induce Parent and the Company to consummate the
transactions contemplated by the Merger Agreement, and for other valuable
consideration (the receipt and sufficiency of which are hereby acknowledged by
Affiliate), Affiliate hereby covenants and agrees as follows:
 
    1.  REPRESENTATIONS AND WARRANTIES.  Affiliate represents and warrants to
Parent as follows:
 
        (A) Affiliate is the holder and "beneficial owner" (as defined in Rule
    13d-3 under the Securities Exchange Act of 1934, as amended) of the number
    of shares of the Parent Common Stock set forth under Affiliate's signature
    below (the "PARENT SHARES"), and Affiliate has good and valid title to the
    Parent Shares, free and clear of any liens, pledges, security interests,
    adverse claims, equities, options, proxies, charges, encumbrances or
    restrictions of any nature.
 
        (B) Affiliate has carefully read this Agreement, and has discussed with
    Affiliate's own independent counsel to the extent Affiliate felt necessary
    the limitations imposed on Affiliate's ability to sell, transfer or
    otherwise dispose of the shares of Parent Common Stock. Affiliate fully
    understands the limitations this Agreement places upon Affiliate's ability
    to sell, transfer or otherwise dispose of the Parent Shares.
 
        (C) Affiliate understands that the representations, warranties and
    covenants set forth herein will be relied upon by Parent, the Company, and
    their respective affiliates, counsel and accounting firms for purposes of
    determining Parent's eligibility to account for the Merger as a "pooling of
    interests,"
 
                                                                  EXECUTION COPY
 
                                       1
<PAGE>
    and that substantial losses and damages may be incurred by these persons if
    Affiliate's representations, warranties or covenants are breached.
 
    2.  COVENANTS RELATED TO POOLING OF INTERESTS.  In accordance with SEC Staff
Accounting Bulletin No. 65 ("SAB 65"), during the period contemplated by SAB 65,
until the earlier of (i) Parent's public announcement of financial results
covering at least thirty (30) days of combined operations of Parent and the
Company or (ii) the Merger Agreement is terminated in accordance with its terms,
Affiliate will not sell, exchange, transfer, pledge, distribute, or otherwise
dispose of or grant any option, establish any "short" or put-equivalent position
with respect to or enter into any similar transaction (through derivatives or
otherwise) intended or having the effect, directly or indirectly, to reduce its
risk relative to any Parent shares. Parent may, at its discretion, place a stock
transfer notice consistent with the restrictions referred to in this Section 2
with its transfer agent with respect to such certificates, provided such
restrictive legend shall be removed and/or notice shall be countermanded
promptly upon expiration of the necessity therefor at the request of Affiliate.
 
    3.  PERMITTED TRANSFERS.  Notwithstanding anything to the contrary contained
in this Agreement, Affiliate may (i) transfer a "de minimis" amount of Parent
Common Stock as contemplated by SEC Staff Accounting Bulletin No. 76 contingent
upon consultation with legal counsel for Parent as to whether such transfer
qualifies as "de minimis" and (ii) may (with the written consent of Parent, not
to be unreasonably withheld): (A) transfer shares of Parent Common Stock in
payment of the exercise price of options to purchase Parent Common Stock; (B)
transfer shares of Parent Common Stock to any organization qualified under
Section 501(c)(3) of the Internal Revenue Code of 1986, as amended, so long as
such organization has traditionally been supported by contributions from the
general public (as opposed to being supported largely by a specific donor); and
(C) transfer shares of Parent Common Stock to a trust established for the
benefit of Affiliate and/or for the benefit of one or more members of
Affiliate's family, or make a bona fide gift of Parent Common Stock to one or
more members of Affiliate's family, provided that in the case of a transfer or
gift pursuant to this clause (B) or (C), a transferee of such shares agrees to
be bound by the limitations set forth in this Agreement.
 
    4.  SPECIFIC PERFORMANCE.  The parties agree that irreparable damage would
occur in the event that any of the provisions of this Agreement was not
performed in accordance with its specific terms or was otherwise breached.
Affiliate agrees that, in the event of any breach or threatened breach by
Affiliate of any covenant or obligation contained in this Agreement, Parent
shall be entitled (in addition to any other remedy that may be available to it,
including monetary damages) to seek and obtain (a) a decree or order of specific
performance to enforce the observance and performance of such covenant or
obligation, and (b) an injunction restraining such breach or threatened breach.
 
    5.  INDEPENDENCE OF OBLIGATIONS.  The covenants and obligations of Affiliate
set forth in this Affiliate Agreement shall be construed as independent of any
other agreement or arrangement between Affiliate, on the one hand, and Parent,
on the other. The existence of any claim or cause of action by Affiliate against
Parent shall not constitute a defense to the enforcement of any of such
covenants or obligations against Affiliate.
 
    6.  NOTICES.  Any notice or other communication required or permitted to be
delivered under this Agreement shall be in writing and shall be deemed properly
delivered, given and received when delivered (by hand, by registered mail, by
courier or express delivery service or by facsimile confirmation) to the address
or facsimile telephone number set forth beneath the name of such party below (or
