                                                         -------   



          WHEREAS the respective Boards of Directors of Parent, Sub and the
Company have approved the acquisition of the Company by Parent on the terms and
subject to the conditions set forth in this Agreement;

          WHEREAS, in furtherance of such acquisition, Parent proposes to cause

                                        -----                                 
the Company has adopted resolutions approving the Offer and the Merger (as
defined below), recommending that the Company's stockholders accept the Offer
and approving the acquisition of Shares and the associated Rights by Sub
pursuant to the Offer and the Stockholder Agreement (as defined herein);

          WHEREAS the respective Boards of Directors of Parent, Sub and the
Company have each approved the merger of Sub into the Company (the "Merger"),
                                                                    ------   
upon the terms and subject to the conditions set forth in this Agreement,
whereby each Share, other than Shares owned directly or indirectly by Parent or
the Company and Dissenting Shares (as defined in Section 3.1(d)), will be
converted into the right to receive the price per share paid in the Offer;

          WHEREAS, concurrently with the execution of this Agreement and as an
inducement to Parent to enter into this Agreement, Parent, Sub and certain
stockholders of the Company are entering into a Stockholder Agreement (the
"Stockholder Agreement") pursuant to which such stockholders have, among other
- ----------------------                                                        
things, agreed to sell all of such stockholders' Shares to Sub at a cash price
per Share equal to the Offer Price, upon the terms and subject to the conditions
set forth in the Stockholder Agreement;

          WHEREAS, concurrently with the execution of this Agreement and as an
inducement to Parent to enter into this Agreement, Parent and certain
stockholders of the Company who are employed by the Company are executing and
delivering the Employment Agreements, attached hereto as Exhibits B - E (the
"Employment Agreements") pursuant to which such stockholders have, among other
- ----------------------                                                        
things, agreed to certain non-competition and non- solicitation covenants; and

 
          WHEREAS Parent, Sub and the Company desire to make certain
representations, warranties, covenants and agreements in connection with the

the Merger.

          NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants and agreements herein contained, and intending to be legally bound
hereby, Parent, Sub and the Company hereby agree as follows:

                                   ARTICLE I

                                   THE OFFER

1.1.   The Offer.
       --------- 

          (a) Subject to the terms and conditions set forth in this Agreement,
within five business days after the date of the public announcement, which shall
occur on the date hereof or the following day, by Parent and the Company of this
Agreement, Sub shall, and Parent shall cause Sub to, commence (within the
meaning of Rule 14d-2 under the Exchange Act (as hereinafter defined)) the
Offer. The obligation of Sub to, and of Parent to cause Sub to, commence the
Offer, conduct and consummate the Offer as soon as practicable after the date
hereof and accept for payment, and pay for, any Shares tendered and not
withdrawn pursuant to the Offer shall be subject only to the conditions set
forth in Exhibit A (the "Offer Conditions") (any of which may be waived in whole
                         ----------------
or in part by Sub in its sole discretion, provided that, without the express
written consent of the Company, Sub may not waive the Minimum Condition (as
defined in Exhibit A)). Sub expressly reserves the right, subject to compliance
with the Exchange Act, to modify the terms of the Offer, except that, without
the express written consent of the Company, Sub shall not (i) reduce the number
of Shares subject to the Offer, (ii) reduce the Offer Price, (iii) add to or
modify the Offer Conditions, including the Minimum Condition, (iv) except as
provided in the next sentence, extend the Offer, if all of the Offer Conditions
are satisfied or waived, (v) change the form of consideration payable in the
Offer or (vi) amend or alter any term of the Offer in any manner materially
adverse to the holders of the Shares, provided, however, that nothing contained
herein shall prohibit Sub, in its sole discretion without the consent of the
Company, from waiving satisfaction of any condition to the Offer other than the
Minimum Condition. Notwithstanding the foregoing, Sub may, without the consent
of the Company, (A) extend the Offer for a specified period, if at the then
scheduled or any extended expiration date of the Offer any of the Offer
Conditions shall not be satisfied or waived, until such time as such conditions
are satisfied or waived, (B) extend the Offer for any period required by any
rule, regulation, interpretation or position of the Securities and Exchange
Commission (the "SEC") or the staff thereof applicable to the Offer, (C) extend
                 ---
the Offer pursuant to Section 9.1(d) and (D) extend the Offer for any reason on
one or more occasions for an aggregate period of not more than 10 business days
beyond the latest expiration date that would be permitted under clause (A), (B)
or (C) of this sentence. Subject to the terms and conditions of the Offer and
this Section 1.1(a), Sub shall, and Parent shall cause Sub to, accept for
payment, and pay for, all Shares validly tendered and not withdrawn pursuant to
the Offer 

                                      -2-

 
that Sub becomes obligated to accept for payment, and pay for, pursuant to the
Offer as soon as practicable after the expiration of the Offer.

          (b) On the date of commencement of the Offer, Parent and Sub shall
file with the SEC a Tender Offer Statement on Schedule 14D-1 (the 
"Schedule 14D-1") with respect to the Offer, which shall contain an offer to
 --------------
purchase and a related letter of transmittal (such Schedule 14D-1 and the
documents included therein pursuant to which the Offer will be made, together
with any supplements or amendments thereto, the "Offer Documents"). Parent and
                                                 ---------------
Sub agree that the Offer Documents shall comply as to form in all material
respects with the Securities Exchange Act of 1934, as amended and the rules and
regulations promulgated thereunder (the "Exchange Act"), and the Offer
                                         ------------
Documents, on the date first published, sent or given to the Company's
stockholders, shall not contain any untrue statement of a material fact or omit
to state any material fact required to be stated therein or necessary in order
to make the statements therein, in light of the circumstances under which they
were made, not misleading, except that no representation or warranty is made by
Parent or Sub with respect to written information supplied by or on behalf of
the Company or any of its stockholders for inclusion or incorporation by
reference in the Offer Documents. Parent, Sub and the Company each agrees
promptly to correct any written information provided by it for use in the Offer
Documents if and to the extent that such information shall have become false or
misleading in any material respect, and Parent and Sub further agree to take all
steps necessary to cause the Schedule 14D-1 as so corrected to be filed with the
SEC and the other Offer Documents as so corrected to be disseminated to holders
of Shares, in each case as and to the extent required by applicable Federal
securities laws. The Company and its counsel shall be given reasonable
opportunity to review and comment upon the Offer Documents prior to their filing
with the SEC or dissemination to the stockholders of the Company. Parent and Sub
agree to provide the Company and its counsel any comments Parent, Sub or their
counsel may receive from the SEC or its staff with respect to the Offer
Documents promptly after the receipt of such comments.

          (c) Parent shall provide or cause to be provided to Sub on a timely
basis the funds sufficient to accept for payment, and pay for, any and all
Shares that Sub becomes obligated to accept for payment, and pay for, pursuant
to the Offer.

1.2.   Company Actions.
       --------------- 

          (a) The Company hereby approves of and consents to the Offer and
represents that the Board of Directors of the Company, at a meeting duly called
and held, duly and unanimously adopted resolutions approving this Agreement and
the Stockholder Agreement, the Offer and the Merger, determining that the terms
of the Offer and the Merger are fair to, and in the best interests of, the
Company and its stockholders and recommending that the Company's stockholders
accept the Offer, tender their Shares and the associated Rights pursuant to the
Offer and approve and adopt the Merger and this Agreement (if required). The
Company represents that its Board of Directors has received the opinion of Smith
Barney Inc. ("Smith Barney") dated the date of this Agreement to the effect
that, as of such date and based upon and subject to the matters set forth
therein, the cash consideration to be received by the holders of Shares (other
than Parent and its Affiliates) pursuant to the Offer and the Merger is fair
                    ----------
from a financial point of view to such holders, and a complete and correct
signed copy of such opinion will be

                                      -3-

 
delivered by the Company to Parent after receipt thereof by the Company. The
Company has been authorized by Smith Barney to permit the inclusion of such
opinion (or a reference thereto) in the Schedule 14D-1, the Schedule 14D-9 (as
hereinafter defined) and the Proxy Statement (as hereinafter defined).

          (b) On the date the Offer Documents are filed with the SEC, or
promptly thereafter, the Company shall file with the SEC a
Solicitation/Recommendation Statement on Schedule 14D-9 with respect to the
Offer (such Schedule 14D-9, as amended from time to time, the "Schedule 14D-9")
                                                               --------------
containing the recommendation described in paragraph (a) and shall mail the
Schedule 14D-9 to the stockholders of the Company. The Schedule 14D-9 shall
comply as to form in all material respects with the requirements of the Exchange
Act and the rules and regulations promulgated thereunder and, on the date filed
with the SEC and on the date first published, sent or given to the Company's
stockholders, shall not contain any untrue statement of a material fact or omit
to state any material fact required to be stated therein or necessary in order
to make the statements therein, in light of the circumstances under which they
were made, not misleading, except that no representation or warranty is made by
the Company with respect to written information supplied by or on behalf of
Parent or Sub for inclusion in the Schedule 14D-9. Each of the Company, Parent
and Sub agrees promptly to correct any written information provided by it for
use in the Schedule 14D-9 if and to the extent that such information shall have
become false or misleading in any material respect, and the Company further
agrees to take all steps necessary to amend or supplement the Schedule 14D-9 and
to cause the Schedule 14D-9 as so amended or supplemented to be filed with the
SEC and disseminated to the Company's stockholders, in each case as and to the
extent required by applicable Federal securities laws. Parent and its counsel
shall be given reasonable opportunity to review and comment upon the Schedule
14D-9 prior to its filing with the SEC or dissemination to stockholders of the
Company. The Company agrees to provide Parent and its counsel any comments the
Company or its counsel may receive from the SEC or its staff with respect to the
Schedule 14D-9 promptly after the receipt of such comments.

          (c) In connection with the Offer and the Merger, the Company shall
cause its transfer agent to furnish Sub promptly with mailing labels containing
the names and addresses of the record holders of Shares as of a recent date and
of those persons becoming record holders subsequent to such date, together with
copies of all lists of stockholders, security position listings and computer
files and all other information in the Company's possession or control regarding
the beneficial owners of Shares, and shall furnish to Sub such information and
assistance (including updated lists of stockholders, security position listings
and computer files) as Parent may reasonably request in communicating the Offer
to the Company's stockholders. Subject to the requirements of applicable law,
and except for such steps as are necessary to disseminate the Offer Documents
and any other documents necessary to consummate the Merger, Parent and Sub and
their agents shall hold in confidence the information contained in any such
labels, listings and files, will use such information only in connection with
the Offer and the Merger and, if this Agreement shall be terminated, will, upon
request, promptly deliver, and will use their best efforts to cause their agents
promptly to deliver, to the Company all copies of such information then in their
possession or control.

                                      -4-

 
          (d) Immediately after consummation of the Offer, each outstanding
Warrant (as defined in Section 7.4) to purchase Common Stock of the Company
issued under the Company's 1995 Directors Warrant Plan held by a director of the
Company (a "Director Warrant"), shall be purchased by Sub for an amount in cash,
            ----------------
payable at the time of such purchase, equal to the product of (x) the number of
shares subject to such Director Warrant and (y) the excess of the price paid in
the Offer over the per share exercise price of such Director Warrant.


                                  ARTICLE II

on the part of the holder of any Shares or any shares of capital stock of Sub:

          (a) Capital Stock of Sub.  Each issued and outstanding share of
              --------------------
capital stock of Sub shall be converted into and become one fully paid and
nonassessable share of Common Stock, par value $.01 per share, of the Surviving
Corporation.

          (b) Cancellation of Treasury Stock and Parent Owned Stock. Each share
              -----------------------------------------------------
of the Common Stock of the Company that is owned by the Company and each Share
that is owned by Parent, Sub or any other direct or indirect wholly owned
subsidiary of Parent shall automatically be canceled and retired and shall cease
to exist, and no consideration shall be delivered in exchange therefor.

                                      -6-

 
          (c) Conversion of Company Common Stock. Subject to Section 3.1(d),
              ----------------------------------
each issued and outstanding Share (other than shares to be canceled in
accordance with Section 3.1(b)), together with the associated Rights, shall be
converted into the right to receive from the Surviving Corporation in cash,
without interest, the price actually paid in the Offer (the "Merger
                                                             ------
Consideration"). As of the Effective Time, all such Shares (and the associated
- -------------
Rights) shall no longer be outstanding and shall be canceled and retired
automatically and shall cease to exist, and each holder of a certificate
representing any such Shares shall cease to have any rights with respect
thereto, except the right to receive the Merger Consideration, without interest.

          (d) Shares of Dissenting Stockholders. Notwithstanding anything in
              ---------------------------------
this Agreement to the contrary, any issued and outstanding Shares held by a
person (a "Dissenting Stockholder") who has neither voted in favor of the Merger
           ----------------------
nor consented in writing thereto and otherwise complies with all the applicable
provisions of the DGCL concerning the right of holders of Company Common Stock
to dissent from the Merger and require appraisal of their Shares ("Dissenting
                                                                   ----------
Shares") shall not be converted as described in Section 3.1(c) but shall become
- ------
the right to receive such consideration as may be determined to be due to such
Dissenting Stockholder pursuant to the laws of the State of Delaware. If, after
the Effective Time, such Dissenting Stockholder withdraws his demand for
appraisal or fails to perfect or otherwise loses his right of appraisal, in any
case pursuant to the DGCL, his Shares shall be deemed to be converted as of the
Effective Time into the right to receive the Merger Consideration. The Company
shall give Parent (i) prompt notice of any demands for appraisal of Shares
received by the Company and (ii) if and after Sub shall have accepted for
payment Shares pursuant to and subject to the conditions of the Offer (including
the Minimum Condition) the opportunity to participate in and direct all
negotiations and proceedings with respect to any such demands. The Company shall
not, without the prior written consent of Parent, make any payment with respect
to, or settle, offer to settle or otherwise negotiate, any such demands.

3.2.   Exchange of Certificates.
       ------------------------ 

          (a) Paying Agent. Prior to the Effective Time, Parent shall designate
              ------------
a commercial bank or trust company to act as paying agent in the Merger (the
"Paying Agent"). Parent shall cause the Surviving Corporation to deposit with
 ------------
the Paying Agent in separate trust for holders of the Certificates (as
hereinafter defined) immediately available funds in an amount sufficient for the
payment of the aggregate Merger Consideration for the shares converted pursuant
to Section 3.1(c) (it being understood that any and all interest earned on funds
made available to the Paying Agent pursuant to this Agreement shall be turned
over to Parent).

          (b) Exchange Procedure.  As soon as reasonably practicable after the
              ------------------                                              
Effective Time, the Paying Agent shall mail to each holder of record of a
certificate or certificates that immediately prior to the Effective Time
represented Shares (the "Certificates"), (i) a letter of transmittal (which
                         ------------                                      
shall specify that delivery shall be effected, and risk of loss and title to the
Certificates shall pass, only upon delivery of the Certificates to the Paying
Agent and shall be in a form and have such other provisions as Parent may
reasonably specify) and (ii) instructions for use in effecting the surrender of
the Certificates in exchange for the Merger Consideration.  Upon surrender of a
Certificate for cancellation to the Paying Agent or to such other agent or
agents as may be appointed by Parent, together with such letter of transmittal,
duly executed, and such 

                                      -7-

 
other documents as may reasonably be required by the Paying Agent, the holder of
such Certificate shall be entitled to receive in exchange therefor, and the
Paying Agent shall pay pursuant to irrevocable instructions given by Sub or
Parent, the amount of cash into which the Shares theretofore represented by such
Certificate shall have been converted pursuant to Section 3.1, and the
Certificate so surrendered shall forthwith be canceled. In the event of a
transfer of ownership of Shares that is not registered in the transfer records
of the Company, payment may be made to a person other than the person in whose
name the Certificate so surrendered is registered, if such Certificate shall be
properly endorsed or otherwise be in proper form for transfer and the person
requesting such payment shall pay any transfer or other taxes required by reason
of the payment to a person other than the registered holder of such Certificate
or establish to the satisfaction of the Surviving Corporation that such tax has
been paid or is not applicable. Until surrendered as contemplated by this
Section, each Certificate shall be deemed at any time after the Effective Time
to represent only the right to receive upon such surrender the amount of cash,
without interest, into which the Shares theretofore represented by such
Certificate shall have been converted pursuant to Section 3.1. No interest will
be paid or will accrue on the cash payable upon the surrender of any
Certificate.

          (c) No Further Ownership Rights in Company Common Stock. All cash paid
              ---------------------------------------------------
upon the surrender of Certificates in accordance with the terms of this Article
III shall be deemed to have been paid in full satisfaction of all rights
pertaining to the Shares formerly represented by such Certificates. At the
Effective Time, the stock transfer books of the Company shall be closed, and
there shall be no further registration of transfers on the stock transfer books
of the Surviving Corporation of the Shares that were outstanding immediately
prior to the Effective Time. If, after the Effective Time, Certificates are
presented to the Surviving Corporation or the Paying Agent for any reason except
notation thereon that a stockholder has elected to exercise his right to
appraisal pursuant to the DGCL they shall be canceled and exchanged as provided
in this Article III.

          (d) No Liability. Any funds deposited with the Paying Agent that
              ------------
remain unclaimed by the former stockholders of the Company for three (3) months
after the Effective Time shall be paid to the Surviving Corporation upon demand,
and any former stockholders of the Company who have not theretofore complied
with the instructions for exchanging their Certificates provided herein shall
thereafter look only to the Surviving Corporation for payment of their claims
for the Merger Consideration set forth in Section 3.1 hereof for each Share held
by such stockholder, without any interest thereon. None of Parent, Sub, the
Company or the Paying Agent shall be liable to any person in respect of any cash
delivered to a public official pursuant to any applicable abandoned property,
escheat or similar law. If any Certificates shall not have been surrendered
prior to seven years after the Effective Time (or immediately prior to such
earlier date on which any payment pursuant to this Article III would otherwise
escheat to or become the property of any Governmental Entity (as defined in
Section 4.5)), the cash payment in respect of such Certificate shall, to the
extent permitted by applicable law, become the property of the Surviving
Corporation, free and clear of all claims or interests of any person previously
entitled thereto.

adverse effect (as defined in Section 10.3) or prevent or materially delay the

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

                                                     -----
referred to herein as "Pension Plans"), "employee welfare benefit plans" (as

benefit of any current or former employees, officers or directors of the Company
or dependents of any such person (collectively, "Benefit Plans"). The Company

its terms. The Company and each Subsidiary and all the Benefit Plans are all in
compliance in all material respects, and all Benefit Plans have been operated
and administered in all material respects with applicable provisions of ERISA
and the Code, and no "reportable event," or "prohibited transaction" (as such
terms are defined in ERISA and the Code, as applicable), or termination has
occurred with respect to any Benefit Plan, and the consummation of the
transaction entered into pursuant to this Agreement will not result in the
occurrence of any such event.

          (b)  Except as disclosed in Schedule 4.15(b), all Pension Plans
                                      ----------------
intended to qualify under Section 401(a) of the Code have been the subject of

has been revoked nor has any such Pension Plan been amended since the 


                                     -17-

 
date of its most recent determination letter or application therefor in any
respect, and no event has occurred that would adversely affect its qualification
or materially increase its costs. All amendments to Pension Plans required under

the five year period immediately preceding the date hereof maintained,
contributed to or been obligated to contribute to any Benefit Plan that is

419 (e) of the Code, (2) each such Benefit Plan that is a "group health plan",

substantially with the applicable requirements of Section 4980B(f) of the Code

agreements or undertakings, written or oral, that would prevent any such plan
(including any such plan covering retirees or other former employees) from being
amended or terminated without material liability to the Company or any
Subsidiary on or at any time after the Effective Time. Except as set forth in
Schedule 4.15(d), no Benefit Plan that is a welfare benefit plan provides for
post-retirement medical or life insurance benefits coverage to any current or
former employee, officer, or director of the Company or any dependent of any
such individual except as may be required under Section 4980B of the Code.

         (e)  Except as set forth on Schedule 4.15(e) and except with respect to

entitled to any additional compensation or benefits or any acceleration of the
time of payment or vesting of any compensation or benefits under any Benefit
Plan as a result of the transactions contemplated by this Agreement. It shall be

by, or accelerated to, any such employee or director as a result of the
termination of such individual's employment/service relationship by the
Surviving Corporation after the Effective Time.

                                     -18-

 
an adequate reserve for all taxes payable by the Company or any Subsidiary for
all taxable periods and portions thereof through the date of such financial

proposed, asserted or assessed against the Company or any Subsidiary, and no
requests for waivers of the time to assess any such taxes are pending. None of

examined by the United States Internal Revenue Service. As of March 31, 1997
(assuming the Company's taxable year closed on such date), the Company and its
Subsidiaries had consolidated Federal net operating loss carryforwards (the "NOL
                                                                             ---

Carryforwards, identifies which amounts are currently limited under Section 382
of the Code or the "separate return limitation year" ("SRLY") rules of the
                                                       ----
consolidated return regulations, and, in the case of NOL Carryforwards currently
limited under Section 382 of the Code, the relevant Section 382 limitation
(within the meaning of Section 382(b) (1) of the Code). As used in this
Agreement, "taxes" shall mean all Federal, state, local and foreign income,
            -----
property, sales, payroll, employment, excise, withholding and other taxes,
tariffs or other governmental charges in the nature of a tax as well as any
interest, penalties and additions to tax.

pursuant to the Benefit Plans or any executed and delivered agreements between
the Company or any Subsidiary and any officer, director or employee thereof in
effect as of the date hereof (whether in cash or property or the vesting of
property) as a result of any of the transactions contemplated by this Agreement
by any employee, officer or director of the Company or any Subsidiary who is a
"disqualified individual" (as such term is defined in proposed Treasury
Regulation Section 1.280G-1) under any employment, severance, change-in-control
or termination agreement, other compensation arrangement or Benefit Plan
currently in effect would be an "excess parachute payment" (as such term is
defined in Section 280G(b) (1) of the Code).  No disqualified individual is
entitled to receive any additional payment from the Company, any Subsidiary, the
Surviving Corporation, or any other person referred to in Q&A 10 under proposed
Treasury Regulation Section 1.280G-1 (a "Parachute Gross-Up Payment") in the
                                         --------------------------         
event that the 20 per cent parachute excise tax of Section 4999(a) of the Code
is imposed on such person.  Except as set forth in Schedule 4.17, neither the
                                                   -------------

person under the Rights Agreement or enable or require any outstanding rights to
be exercised, distributed or triggered, and that the Rights (as defined in the
Rights Agreement) will expire without any further force or effect as of the
Effective Time. Other than Parent and Sub (and their Affiliates), the Company

Parent orally and in writing of any request for information or of any proposal

such employee, in which such employee 

                                      -29-

 
certifies that such employee has paid in full all taxes applicable to the

7.1    Stockholder Approval; Preparation of Proxy Statement.
       ---------------------------------------------------- 

         (a)  If the Company Stockholder Approval is required by law, the
Company will, as soon as practicable following the acceptance for payment of,
and payment for, Shares by Sub pursuant to and subject to the conditions
(including the Minimum Condition) of the Offer, duly call, give notice of,
convene and hold a meeting of its stockholders (the "Stockholders Meeting") for
                                                     --------------------    
the purpose of obtaining the Company Stockholder Approval. The Company will,
through its Board of Directors, and subject to such board's fiduciary duties
under applicable law following receipt of written advice of counsel, recommend
to its stockholders that the Company Stockholder Approval be given.
Notwithstanding the foregoing, if Sub or any other subsidiary of Parent shall
acquire at least 90% of the outstanding Shares, the parties shall, at the
request of Parent, take all necessary and appropriate action to cause the Merger
to become effective as soon as practicable after the expiration of the Offer
without a Stockholders Meeting in accordance with Section 253 of the DGCL.

         (b)  If the Company Stockholder Approval is required by law, the
Company will, at Parent's request, as soon as practicable following the
expiration of the Offer, prepare and file a preliminary Proxy Statement with the
SEC and will use its best efforts to respond to any comments of the SEC or its
staff and to cause the Proxy Statement to be mailed to the Company's
stockholders as promptly as practicable after responding to all such comments to
the satisfaction of the staff. The Company will notify Parent promptly of the
receipt of any comments from the SEC or its staff and of any request by the SEC
or its staff for amendments or supplements to the Proxy Statement or for
additional information and will supply Parent with copies of all correspondence
between the Company or any of its representatives, on the one hand, and the SEC
or its staff, on the other hand, with respect to the Proxy Statement or the
Merger. If at any time prior to the Stockholders Meeting there shall occur any
event that should be set forth in an amendment or supplement to the Proxy
Statement, the Company will promptly prepare and mail to its stockholders such
an amendment or supplement. The Company will not mail any Proxy Statement, or
any amendment or supplement thereto, to which Parent reasonably objects, unless
required by law, rule, regulation or the SEC staff, in the opinion of outside
counsel; provided, that Parent shall identify its objections and fully cooperate
         --------      
with the Company to create a mutually satisfactory Proxy Statement. In
connection with such preliminary proxy statement, Proxy Statement and any
amendment or supplement thereto, Parent and Sub should promptly provide all
information reasonably requested by the Company.

         (c)  Parent agrees to cause all Shares purchased pursuant to the Offer
and all other Shares owned by Parent or any subsidiary of Parent to be voted in
favor of the Company Stockholder Approval.

                                      -31-

 
7.2    Access to Information; Confidentiality.
       -------------------------------------- 

       The Company and its Subsidiaries shall afford to Parent, and to Parent's
officers, employees, accountants, counsel, financial advisers and other
representatives, reasonable access during normal business hours from the date
hereof to the Effective Time to all their respective properties, books,
contracts, commitments, personnel and records and, during such period, the
Company shall furnish promptly to Parent (a) a copy of each report, schedule,
registration statement and other document filed by it during such period
pursuant to the requirements of Federal or state securities laws and (b) all
other information concerning its business, properties and personnel as Parent
may reasonably request.  Except as required by law, Parent will hold, and will
cause its officers, employees, accountants, counsel, financial advisers and
other representatives and Affiliates to hold, any and all information received
from the Company, directly or indirectly, in confidence, according to the terms
of the confidentiality agreement dated as of April 2, 1997, between the Company
and an affiliate of Parent (the "Confidentiality Agreement").

7.3    Reasonable Efforts; Notification.
       -------------------------------- 

         (a)  Upon the terms and subject to the conditions set forth in this
Agreement, each of the parties agrees to use all reasonable efforts to take, or
cause to be taken, all actions, and to do, or cause to be done, and to assist
and cooperate with the other parties in doing, all things necessary, proper or
advisable to consummate and make effective, in the most expeditious manner
practicable, the Offer and the Merger, and the other transactions contemplated
by this Agreement, including (i) the obtaining of all necessary actions or
nonactions, waivers, consents and approvals from Governmental Entities and the
making of all necessary registrations and filings (including filings with
Governmental Entities, if any) and the taking of all reasonable steps as may be
necessary to obtain an approval or waiver from, or to avoid an action or
proceeding by, any Governmental Entity, (ii) the obtaining of all necessary
consents, approvals or waivers from third parties, (iii) the defending of any
lawsuits or other legal proceedings, whether judicial or administrative,
challenging this Agreement or the consummation of any of the transactions
contemplated by this Agreement, including seeking to have any stay or temporary
restraining order entered by any court or other Governmental Entity vacated or
reversed, (iv) the execution and delivery of any additional instruments
necessary to consummate the transactions contemplated by, and to fully carry out
the purposes of, this Agreement, and (v) reasonably cooperating with all
potential sources of financing to Parent in connection with the Offer, the
Merger, and the other transactions contemplated by this Agreement, and the
taking of all reasonable steps as may be necessary or advisable to consummate
one or more lending transactions with such potential sources of financing.  In
connection with and without limiting the foregoing, the Company and its Board of
Directors shall (i) take all action necessary to ensure that no state takeover
statute or similar statute or regulation is or becomes applicable to the Offer,
the Merger, this Agreement, the Stockholder Agreement or any of the other
transactions contemplated by this Agreement or the Stockholder Agreement and
(ii) if any state takeover statute or similar statute or regulation becomes
applicable to the Offer, the Merger, this Agreement, the Stockholder Agreement
or any other transaction contemplated by this Agreement or the Stockholder
Agreement, take all action reasonably necessary to ensure that the Offer, the
Merger and the other transactions contemplated by this Agreement may be
consummated as 

                                      -32-

 
promptly as practicable on the terms contemplated by this Agreement and
otherwise to minimize the effect of such statute or regulation on the Offer, the
Merger, this Agreement, the Stockholder Agreement and the other transactions
contemplated by this Agreement or the Stockholder Agreement. Nothing in this
Agreement shall be deemed to require Parent to dispose of or hold separate any
asset or collection of assets.

         (b)  The Company shall give prompt notice to Parent of, to the
knowledge of the Company (i) any representation or warranty made by it contained
in this Agreement becoming untrue or inaccurate or (ii) the failure by it or any
Subsidiary to comply with or satisfy any covenant, condition or agreement to be
compiled with or satisfied by it or any Subsidiary under this Agreement;
provided, however, that no such notification shall affect the representations,
- --------  -------

obligations of the parties under this Agreement.

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

         (a)  As soon as practicable following the date hereof but in no event
later than the consummation of the Offer, the Company (or, if appropriate, the
Board of Directors of the Company or any committee administering the Stock
Option Plans (as defined below)) shall (including by adopting resolutions or
taking any other actions) take action so as to allow each outstanding option to
purchase Shares (a "Company Stock Option") heretofore granted under any stock
                    --------------------  
option, stock appreciation rights or stock purchase plan, program or arrangement
of the Company (collectively, the "Stock Option Plans") and each outstanding
                                   ------------------
warrant or other right to purchase Shares (a "Warrant") in each case outstanding
                                              -------
immediately prior to the date hereof (except the Director Warrants), whether or
not then exercisable, either (i) shall be canceled immediately after
consummation of the Offer in exchange for an amount in cash, payable at the time
of such cancellation, equal to the product of (x) the number of Shares subject
to such Company Stock Option or Warrant immediately prior to the Effective Time
and (y) the excess of the price per Share to be paid in the Offer over the per
Share exercise price of such Company Stock Option or Warrant (the "Net Amount")
                                                                   ----------  
or (ii) shall be converted immediately prior to the Effective Time into the
right solely to receive the Net Amount; provided, that no such cash payment has
                                        --------                               
been made.  The Company shall not make, or agree to make, any payment of any
kind to any holder of a Company Stock Option or a  Warrant (except for the
payment described above) without the consent of Parent (which consent will not
be unreasonably withheld).

         (b)  All Stock Option Plans shall be terminated as of the Effective
Time and the provisions in any other Benefit Plan providing for the issuance,
transfer or grant of any capital stock of the Company or any interest in respect
of any capital stock of the Company shall be terminated as of the Effective
Time. The Company shall ensure that following the Effective Time, no holder of a
Company Stock Option or Warrant or any participant in any Stock Option Plan
(other than those holders who are parties to an agreement to exchange or roll
their equity interest in the Company for or into equity of Parent or the
Surviving Corporation) shall have any right thereunder to acquire any capital
stock of the Company, Parent or the Surviving Corporation.

                                      -33-

the Net Amount to holders of any Company Stock Options or Warrants converted in
accordance with clause (y) of Section 7.4(a).

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

         (a)  All rights to indemnification and exculpation (including the
advancement of expenses) from liabilities for acts or omissions occurring at or
prior to the Effective Time (including with respect to the transactions
contemplated by this Agreement) existing as of the date hereof in favor of the
current or former directors or officers of the Company as provided in its
Certificate of Incorporation, its By-laws and the indemnification agreements set
forth in Schedule 7.5 shall be assumed by the Surviving Corporation in the
         ------------
Merger, without further action, as of the Effective Time and shall survive the
Merger and shall continue in full force and effect without amendment,
modification or repeal in accordance with their terms for a period of not less
than six years after the Effective Time; provided however, that if any claims
                                         -------- -------
are asserted or made within such period, all rights to indemnification (and to
advancement of expenses) hereunder in respect of any such claims shall continue,
without diminution, until disposition of any and all such claims.

         (b)  The Parent shall cause the Company to use commercially reasonable
efforts to maintain the Company's existing directors and officers liability
insurance (the "D & O Insurance") covering persons who are currently covered by
the Company's D & O Insurance for a period of six (6) years after the Effective
Time on terms no less favorable than those in effect on the date hereof;
provided, however, that the Parent may substitute therefor policies providing at
- -----------------                                                               
least comparable coverage containing terms and conditions no less favorable than
those in effect on the date hereof.

         (c)  The provisions of this Section 7.5 are intended to be for the
benefit of, and will be enforceable by, each indemnified party, his or her heirs
and his or her representatives.

       --------- 

       Promptly upon the acceptance for payment of, and payment for, any
Shares by Sub pursuant to and subject to the conditions (including the Minimum
Condition) of the Offer, Sub shall be entitled to designate such number of
directors on the Board of Directors of the Company as will give Sub, subject to
compliance with Section 14(f) of the Exchange Act, a majority of such directors,
and the Company shall, at such time, cause Sub's designees to be so elected by
its existing Board of Directors. Subject to applicable law, the Company shall
take all action requested by Parent necessary to effect any such election,
including mailing to its stockholders the Information Statement containing the
information required by Section 14(f) of the Exchange Act and Rule 14f-1
promulgated thereunder, and the Company agrees to make such mailing with the
mailing of the Schedule 14D-9 (provided that Parent and Sub shall have provided
to the 

                                      -34-

 
Company on a timely basis in writing all information required to be included in
the Information Statement and Schedule 14D-9 with respect to Sub's designees).
In connection with the foregoing, the Company will promptly, at the option of
Parent, either increase the size of the Company's Board of Directors and/or
obtain the resignation of such number of its current directors as is necessary
to enable Sub's designees to be elected or appointed to, and to constitute a
majority of, the Company's Board of Directors as provided above.

7.7    Fees and Expenses.
       ----------------- 

         (a)  Except as otherwise provided herein and as provided below in this
Section 7.7, all fees and expenses incurred in connection with the Offer, the
Merger, this Agreement and the transactions contemplated by this Agreement shall
be paid by the party incurring such fees or expenses, whether or not the Offer
or the Merger is consummated, except that printing and mailing costs and
expenses shall be shared equally by Parent and the Company.

         (b)  In the event that this Agreement is terminated (i) by Parent or
Sub pursuant to Section 9.1(c), (ii) by Parent pursuant to and in accordance
with Section 9.1(b)(i) in connection with any breach by the Company of any
covenant or agreement (including, without limitation, the covenants set forth in
Section 6.2(b)) or any representation or warranty made by the Company in this
Agreement or (iii) pursuant to Section 9.1(d), the Company shall promptly pay to
Parent in immediately available funds the Termination Fee (as defined herein)
plus all Expenses (as defined herein). Notwithstanding the above (but subject to
the payment of the Termination Fee pursuant to the consummation of an
Alternative Transaction or the execution of an Acquisition Agreement as set
forth below), no Termination Fee shall be payable if any termination by Parent
or Sub is solely (A) pursuant to Section 9.1(b)(i) that is caused solely by a
breach of one or more representations and warranties of the Company that is or
are true and correct as of the date hereof but that becomes untrue hereafter
other than any such breach after the date hereof that results from or arises out
of any act or failure to act by the Company, its Subsidiaries or any of their
respective officers, directors, employees or agents, (B) pursuant to Section
9.1(b)(ii), or (C) pursuant to the failure of the conditions set forth in either
paragraph (c) or paragraph (h) of Exhibit A to be satisfied other than any such
failure which results from or arises out of any act or failure to act by the
Company, its Subsidiaries or any of their respective officers, directors,
employees or agents. The "Termination Fee" shall be equal to 4% of the sum of
                          ---------------
(A) the outstanding consolidated indebtedness of the Company and its
Subsidiaries at the time of termination, determined in accordance with generally
accepted accounting principles consistently applied, plus (B) the product of
(i) the total number of shares outstanding at the time of such termination on a
fully diluted basis and (ii) the Offer Price. If this Agreement shall be
terminated for any reason (other than as set forth in clauses (i), (ii) or (iii)
of this Section 7.7(b) for pursuant to Section 9.1(e)), including a termination
pursuant to which no Termination Fee is paid pursuant to this Section 7.7(b),
then the Company shall pay all Expenses to Parent in immediately funds on the
date of such termination, and if, prior to the one year anniversary of such
termination, either an Alternative Transaction shall be consummated or the
Company shall enter into an Acquisition Agreement providing for an Alternative
Transaction, then the Company shall pay to Parent in immediately available funds
the Termination Fee, such payment to be made on the earlier of the date of
consummation of such Alternative Transaction or the one year anniversary of the
date of the termination of this Agreement. The Company acknowledges that

                                      -35-

 
the agreements contained in this Section 7.7(b) are an integral part of the
transactions contemplated by this Agreement, and that, without these agreements,
Parent would not enter into this Agreement. Accordingly, if the Company fails
promptly to pay the amount due pursuant to this Section 7.7(b), and, in order to
obtain such payment, Parent commences a suit which results in a judgment against
the Company for the fee set forth in this Section 7.7(b), the Company shall pay
to Parent all costs and expenses (including attorneys' fees and expenses) in
connection with such suit, together with interest on the amount of the fee at
the prime rate of the Bankers Trust Company in effect on the date such payment
was required to be made. If such a suit results in a judgment against Parent
and/or Sub, Parent shall pay to the Company all costs and expenses (including
attorney's fees and expenses) in connection with such suit. "Expenses" shall
                                                             --------       
mean all out-of-pocket expenses incurred by Parent and Sub in connection with
this Agreement, the Stockholder Agreement and the transactions contemplated
hereby and thereby, including fees and expenses of its printer, consultants,
attorneys, accountants, and other advisors, not to exceed $1,750,000.

7.8    Public Announcements.
       -------------------- 

       Parent and Sub, on the one hand, and the Company, on the other hand, will
consult with each other before issuing, and provide each other the opportunity
to review and comment upon, any press release or other public statements with
respect to the transactions contemplated by this Agreement, including the Offer
and the Merger, and shall not issue any such press release or make any such
public statement prior to such consultation, except as may be required by
applicable law, court process or by obligations pursuant to any listing
agreement with any national securities exchange or national securities quotation
system.  The parties agree that the initial press release to be issued with
respect to the transactions contemplated by this Agreement shall be in the form
heretofore agreed to by the parties.

7.9    Stop Transfer.
       ------------- 

       The Company shall not register the transfer of any certificate
representing any Subject Shares (as defined in the Stockholder Agreement),
unless such transfer is made to Parent or Sub or otherwise in compliance with
the Stockholder Agreement.  The Company will inscribe upon any certificates
representing Subject Shares tendered by a Stockholder (as defined in the
Stockholder Agreement) for such purpose the following legend:

       "THE SHARES OF COMMON STOCK, $.01 PAR VALUE OF SMT HEALTH SERVICES INC.
       REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A STOCKHOLDERS AGREEMENT
       DATED AS OF JUNE 24, 1997, AND MAY NOT BE SOLD OR OTHERWISE TRANSFERRED,
       EXCEPT IN ACCORDANCE THEREWITH. COPIES OF SUCH AGREEMENT MAY BE OBTAINED
       AT THE PRINCIPAL EXECUTIVE OFFICES OF SMT HEALTH SERVICES INC."

     Conditions the Offer shall have terminated or expired in accordance with
     its terms without Sub having accepted for payment Shares pursuant to and
     subject to the conditions (including the 

                                      -37-

 
     Minimum Condition) of the Offer or (y) Sub shall not have accepted for
     payment Shares pursuant to the Offer prior to September 30, 1997; provided,
                                                                       --------
     however, that if as of such date any of the conditions set forth in either
     -------  
     paragraph (a) or paragraph (b) of Exhibit A are not satisfied, Parent and
     Sub may in their sole discretion extend such date until December 31, 1997;
     and provided, further, that the right to terminate this Agreement pursuant
         --------  -------  
     to this Section 9.1(b) (i) shall not be available to any party whose
     failure to perform any of its obligations under this Agreement results in
     the failure of any such condition or if the failure of such condition
     results from facts or circumstances that constitute a breach of any
     representation or warranty under this Agreement by such party; or

                (ii)  if any Governmental Entity shall have issued an order,
     decree or ruling or taken any other action permanently enjoining,
     restraining or otherwise prohibiting the acceptance for payment of, or
     payment for, Shares pursuant to the Offer or the Merger and such order,
     decree or ruling or other action shall have become final and nonappealable.

        (c)  By Parent or Sub prior to Sub's obligation to accept Shares for
payment pursuant to the Offer in the event of a breach by the Company of any
representation, warranty, covenant or other agreement contained in this
Agreement which would or reasonably would be expected to give rise to the
failure of a condition set forth in Exhibit A.

        (d)  By either Parent or the Company if, prior to the obligation of Sub
to accept Shares for payment pursuant to the Offer, (i) the Board of Directors
of the Company determines that a Third Party Proposal for an Alternative
Transaction constitutes a Superior Proposal (as defined below), (ii) the Company
promptly notifies Parent of its determination in writing (unless, following
receipt of written advice of outside counsel, the Board of Directors' fiduciary
duties under applicable law would be violated thereby), which writing shall set
forth the terms and conditions of the Third Party Proposal and the identity of
the person making the Third Party Proposal, (iii) ten days have elapsed
following receipt by Parent of such written notice, (iv) during such ten day
period the Company cooperates with Parent with the intent of enabling, but not
obligating, Parent to agree to a modification of the terms and conditions of
this Agreement so that the transactions contemplated hereby may be effected, and
(v) at the end of such ten day period, the Board of Directors of the Company
continues to believe that such Third Party Proposal constitutes a Superior
Proposal and the Company pays to Parent the amount specified under Section
7.7(b) pursuant to the terms thereof; provided that in the event the
                                      --------                      
determination of the Board of Directors of the Company that such Third Party
Proposal constitutes a Superior Proposal is made less than ten days prior to the
scheduled expiration of the Offer, Parent and Sub will (in their sole
discretion) either (x) reduce the period described in clause (iii) hereof or (y)
extend the Offer, in either case such that the period described in clause (iii)
hereof will end prior to the expiration of the Offer.  For purposes of this
Agreement, a "Superior Proposal" means any Third Party Proposal to acquire,
              -----------------                                            
directly or indirectly all of the Shares or all or substantially all of the
assets of the Company; provided that (i) the Board of Directors of the Company
                       --------                                               
determines in its good faith judgment (based on the advice of a financial
advisor of nationally recognized reputation) that such Third Party Proposal is
on terms that are more favorable to the Company's stockholders than the Offer
and the Merger (taking into account all relevant factors,

                                      -38-

 
including the amount and form of consideration to be received in respect of the
Shares, the relative value of any non-cash consideration, and the timing and
certainty of closing), (ii) the Board of Directors of the Company determines in
its good faith judgment (based on the written advice of outside counsel) that
the failure to recommend or accept such Third Party Proposal would violate the
fiduciary duties of the Board of Directors of the Company under applicable law,
and (iii) if required, the financing necessary to consummate a transaction
pursuant to such Third Party Proposal is then committed.

        (e)  By the Company, if Sub or Parent shall have (i) failed to commence
the Offer within five business days of the date hereof, (ii) failed to pay for
Shares pursuant to the Offer to the extent required by Section 1.1(a) hereof or
(iii) breached in any material respect any of their respective representations,
warranties, other covenants or other agreements contained in this Agreement,
which breach or failure to perform in respect of clause (iii) is incapable of
being cured or has not been cured within 30 days after the giving of written
notice to Parent or Sub, as applicable, except, in any case under clause (iii),
such breaches and failures which would not prevent the consummation of the Offer
or the Merger subject to the terms and conditions of this Agreement.

9.2.   Effect of Termination.
       --------------------- 

       In the event of a termination of this Agreement by either the Company or
Parent as provided in Section 9.1, this Agreement shall forthwith become void
and there shall be no liability or obligation on the part of Parent, Sub or the
Company or their respective officers or directors, except with respect to the
last sentence of Section 1.2(c), Section 5.6, the last sentence of Section 7.2,
Section 7.7, Section 9.1, this Section 9.2 and Article X; provided, however,
                                                          --------  ------- 
that nothing herein shall relieve any party for liability for any breach hereof.

9.3.   Amendment.
       --------- 

       This Agreement may be amended by the parties hereto, by action taken or
authorized by their respective Boards of Directors, at any time before or after
obtaining the Company Stockholder Approval (if required by law), but, after any
such approval, no amendment shall be made which by law requires further approval
by such shareholders without obtaining such further approval.  This Agreement
may not be amended except by an instrument in writing signed on behalf of each
of the parties hereto.

9.4.   Extension; Waiver.
       ----------------- 

       At any time prior to the Effective Time, the parties hereto, by action
taken or authorized by their respective Boards of Directors, may, to the extent
legally allowed, (i) extend the time for the performance of any of the
obligations or other acts of the other parties hereto, (ii) waive any
inaccuracies in the representations and warranties contained herein or in any
document delivered pursuant hereto or (iii) subject to Section 9.3, waive
compliance with any of the agreements or conditions contained herein.  Any
agreement on the part of a party hereto to any such extension or waiver shall be
valid only if set forth in a written instrument signed on behalf 

                                      -39-

 
of such party. The failure of any party to this Agreement to assert any of its
rights under this Agreement or otherwise shall not constitute a waiver of those
rights.

9.5.   Procedure for Termination, Amendment, Extension or Waiver.
       --------------------------------------------------------- 

       A termination of this Agreement pursuant to Section 9.1, an amendment of
this Agreement pursuant to Section 9.3 or an extension or waiver pursuant to
Section 9.4 shall, in order to be effective, require in the case of Parent, Sub
or the Company, action by its Board of Directors or the duly authorized designee
of its Board of Directors; provided, however, that in the event that Sub's
                           --------  -------                              
designees are appointed or elected to the Board of Directors of the Company as
provided in Section 7.6, after the acceptance for payment and payment of Shares
pursuant to and subject to the Conditions (including the Minimum Condition) of
the Offer and prior to the Effective Time, the affirmative vote of a majority of
the directors of the Company that were not designated by Parent or Sub shall be
required by the Company to (i) amend or terminate this Agreement by the Company,
(ii) exercise or waive any of the Company's rights or remedies under this
Agreement, (iii) extend the time for performance of Parent's and Sub's
respective obligations under this Agreement or (iv) take any action to amend or
otherwise modify the Company's Certificate of Incorporation or By-laws.

documentation to which the Company or any Subsidiary is a party or by which the
assets or properties of either the Company or any Subsidiary are bound
(including those in respect of the MRI Units owned, leased or on order by the
Company or any Subsidiary) shall have been amended or restated, as necessary, so
that (a) all MRI Units leased by the Company and/or any Subsidiary may be
purchased by the applicable lessee at any time, and the leases thereunder and
all lending or other financing arrangements to which the Company or any
Subsidiary is a party pertaining to the MRI Units owned, leased or on order by
the Company or any Subsidiary may be terminated at any time (other than leases
or lending or other financing arrangements with respect to such MRI Units that
have an aggregate principal amount outstanding of less than $6 million), in each
case without any payment made or liability or obligation incurred by or on
behalf of the Company or any Subsidiary, other than payments made or liabilities
or obligations incurred prior to the Effective Time which, in the aggregate, do
not exceed an amount reasonably acceptable to Parent and the Company and (b)
none of the Merger, the Offer or any of the transactions contemplated

                                      A-2

 
hereby shall constitute a violation or breach of, or constitute (with or without
due notice or lapse of time or both) a default (or give rise to any right of
termination, amendment, accelaration or cancellation or right of non-renewal or
give rise to the loss of a material benefit) thereunder; which, in the judgment
of Sub in any such case, and regardless of the circumstances (including any
action or omission by Sub not inconsistent with the terms of this Agreement)
giving rise to any such condition, makes it inadvisable to proceed with such
acceptance for payment or payments.

       The foregoing conditions in paragraphs (a) through (h) are for the sole
benefit of Sub and Parent and may, subject to the terms of this Agreement, be
waived by Sub and Parent in whole or in part at any time and from time to time
in their sole discretion.  The failure by Parent or Sub at any time to exercise
any of the foregoing rights shall not be deemed a waiver of any such right, the
waiver of any such right with respect to particular facts and circumstances
shall not be deemed a waiver with respect to any other facts and circumstances
and each such right shall be deemed an ongoing right that may be asserted at any
time and from time to time.

                        PARENT OPTION PLAN TERMS SHEET

Issuer               Three Rivers Holding Corp. ("Issuer")
                                                  ------

Percent of           10% of the shares outstanding immediately after the 
Outstanding Common   Effective Time of the Merger (assuming 35,000,000 common 
Stock                shares of initial equity before granting of options,
                     options with respect to a total of 3,500,000 shares will
                     be available for grant).

Allocation           Unless the board of directors with the concurrence of 
                     Messrs. Bergman and Dickman unanimously determines 
                     otherwise (except with respect to any employee who has 
                     an employment agreement with SMT Health Services Inc. 
                     (the "Company")), the option shares shall be allocated
                           -------
                     to the individuals and in the amounts set forth on the
                     schedule attached hereto, with any unallocated options to
                     be allocated by the Compensation Committee in consultation
                     with Messrs. Bergman and Dickman.

Time Vesting         50% of the total number of available options will vest over
                     four years (1998, 1999, 2000, 2001), beginning on the first
                     anniversary of the grant date, which will be 15 days after
                     the Effective Time. In the event of a sale of the Company 
                     (as defined below) which is followed within six months by 
                     the termination of an employee, all of the options 
                     described in the preceding sentence allocated to such
                     terminated employee shall vest immediately upon such
                     termination.

Performance Vesting  50% of total available options will vest over four years
                     (4/1/99, 4/1/00, 4/1/01, 4/1/02) in equal increments 
                     conditioned upon achievement of annual equity value 
                     targets. The Per Share Equity targets for each of 12/31/98,
                     12/31/99, 12/31/00 and 12/31/01 are $1.68, $2.35, $3.29 and
                     $4.61. For each target that is achieved, the options 
                     attributable to that year will vest


                                      B-1


 
                on April 1 of the following year. If any target is not achieved,
                the compensation committee of the board, upon consultation with
                management, will have the discretion to cause all or part of
                such options to vest. In addition, for any year in which a Per
                Share Equity target is missed by less than 20%, the shares that
                did not vest in such year shall vest in the next succeeding year
                if the Per Share Equity target for such year is attained. Per
                Share Equity will equal (((i) EBITDA for the relevant calendar
                year times (ii) six) plus ((i) 12/31 cash minus (ii) 12/31
                debt)) divided by (as of 12/31 (i) number of shares outstanding
                plus (ii) number of shares subject to vested options.

                In the event of the sale of the Company (including a merger, the
                sale of substantially all assets, or the sale by Apollo of more
                than 50% of its common stock, if such sale is made to a company
                which after giving effect to such sale will own (i) more than
                25% of the outstanding stock of the Company and (ii) more of the
                common stock of the Company than is owned by Apollo after such
                sale), other than to an affiliate of Apollo, prior to 1/1/03,
                all unvested performance-based options will vest if the fair
                market value of the per share consideration received in the sale
                equals or exceeds the Per Share Equity target established for
                12/31 of the nearest year for which Per Share Equity targets
                have been established after such sale closes.

Exercise Price  Apollo's per share buy-in price.

Expiration Date Options expire ten years from the date of grant.

Tag Along/Drag  Shares purchased pursuant to the options ("Shares") will have 
Along Rights    the benefit of tag along rights if the Issuer is sold and be
                subject to drag along rights in favor of the Issuer and/or the
                controlling stockholder.

                                      B-2


 
Repurchase Right    Vested options and Shares will be subject to repurchase
                    rights in favor of the Issuer and Apollo from and after the
                    first anniversary of termination of employment at the fair
                    market value thereof. If employee terminates without good
                    reason, he must exercise all vested options within 30 days
                    of termination or lose the right to exercise such options
                    (unless such employee continues in a consulting or other
                    material business relationship with the Company in which
                    case such options must be exercised prior to the termination
                    of such consulting or other relationship but in any event
                    within 2 years of the termination of employment), but
                    employee is entitled to the fair market value of shares
                    received upon exercise of such options if the repurchase
                    right is exercised.

Registration Rights An S-8 will be filed within one year of the IPO (as defined 
                    below).

Vesting             Vesting of options will occur only during an employee's 
                    term of employment.

IPO                 If the Issuer sells shares of Common stock in a qualified
                    public offering (the "IPO") before 1/1/03, all unvested
                    performance-based options attributable to the years prior to
                    the year in which the IPO closes vest if the per share net
                    proceeds to the Issuer equal or exceed the Per Share Equity
                    target for 12/31 of the nearest year for which Per Share
                    Equity targets have been established after the IPO closes.

                    The Per Share Equity performance targets for 12/31 of each
                    year after the close of the IPO will be measured against the
                    average closing stock price for the 30 trading days
                    immediately preceding the applicable target date (with the
                    five highest and five lowest prices disregarded).

                    All tag along/drag along rights and repurchase rights 
                    terminate upon consummation of the IPO.
