Item 5.  Other Events.

         On September 8, 1999, NovaCare Employee Services, Inc., a Delaware
corporation (the "Company"), entered into an Agreement and Plan of Merger (the
"Merger Agreement") with Plato Holdings, Inc., a Delaware corporation
("Parent"), and New Plato Acquisition, Inc., a Delaware corporation and wholly
owned subsidiary of Parent ("Merger Sub"), pursuant to which Merger Sub agreed
to commence a cash tender offer (the "Offer") to acquire any and all shares of
the issued and outstanding common stock, $.01 par value ("Common Stock" or
"Shares"), of the Company, for $2.50 per share, net to the seller in cash (the
"Offer Price"). Parent is a newly organized corporation formed in connection
with the Offer and all of the outstanding capital stock of Parent is owned by
Plato Holdings, LLC, a Delaware limited liability company ("Plato LLC"). Plato
LLC is a newly organized limited liability company formed in connection with the
Offer. Plato LLC's equity interests currently are owned approximately: 26.9% by
Fidelity Ventures Limited; 13.5% by Fidelity Investors II Limited Partnership;
6.75% by The P/A Fund III, L.P.; 33.37% by APA Excelsior V, L.P.; 0.28% by The
Patricof Private Investment Club II, L.P.; and 19.2% by AFLAC Incorporated.

         Subsequent to Parent or Merger Sub accepting for payment and paying for
that number of Shares which, when added to any Shares owned beneficially by
Parent or Merger Sub, would constitute a majority of the Shares outstanding on a
fully diluted basis (the "Minimum Condition"), in accordance with applicable law
and subject to the terms and conditions of the Merger Agreement, Merger Sub will
merge with and into the Company, with the Company becoming a wholly owned
subsidiary of Parent (the "Merger"). Upon the consummation of the Merger, each
share of Common Stock outstanding immediately prior to the Merger (other than
Shares owned by Parent or Merger Sub or shares held by stockholders who properly
perfect their
<PAGE>   3
                                                                               3


dissenters' rights under the Delaware General Corporation Law (the "DGCL")) will
be converted into the right to receive the Offer Price.

         The Merger Agreement provides that, upon the purchase by Merger Sub or
Parent or any subsidiary of Parent of a majority of the Shares and from time to
time thereafter, Parent will be entitled to designate such number of directors,
rounded up to the next whole number, on the Board of Directors of the Company
(the "Company Board") so that the percentage of Parent's designees on the
Company Board equals the percentage of outstanding Shares beneficially owned by
Merger Sub, Parent and their affiliates. The Company will take all action
necessary to cause such persons designated by Parent to be appointed or elected
to the Company Board and to secure resignations of such number of its incumbent
directors as is necessary to enable Parent's designees to be so elected or
appointed.

         Consummation of the Merger is conditioned upon, among other things, (i)
the approval and adoption of the Merger Agreement by the holders of a majority
of the outstanding Shares of the Company, if required by applicable law, and
(ii) the approval of the holders of a majority of the outstanding shares of
common stock, $.01 par value, of NovaCare, Inc., a Delaware corporation and
principal stockholder of the Company ("NovaCare"), which such approval occurred
on September 21, 1999.

         Under the DGCL and pursuant to the Company's Certificate of
Incorporation, the affirmative vote of the holders of a majority of the
outstanding Shares is the only vote of any class or series of the Company's
capital stock that would be necessary to approve the Merger Agreement at a
meeting of the Company's stockholders. If Merger Sub purchases a majority of the
outstanding Shares in the Offer (which will be the case if the Minimum Condition
is satisfied and the other conditions to the Offer are satisfied or waived),
Merger Sub will be able to effect
<PAGE>   4
                                                                               4


the Merger without the affirmative vote of any other stockholder. Pursuant to
the Merger Agreement, Parent and Merger Sub have agreed to vote the Shares
acquired by them pursuant to the Offer in favor of the Merger.

         Under Section 253 of the DGCL, if a corporation owns at least 90% of
the outstanding shares of each class of a subsidiary corporation, the
corporation holding such stock may merge such subsidiary into itself, or itself
into such subsidiary, without any action or vote on the part of the board of
directors or the stockholders of such other corporation (a "short-form merger").
In the event that Merger Sub acquires in the aggregate at least 90% of the
outstanding Shares pursuant to the Offer or otherwise, then, at the election of
Parent, a short-form merger could be effected without any further approval of
the Company Board or the stockholders of the Company.

         Even if Merger Sub does not own 90% of the outstanding Shares following
consummation of the Offer, Parent or Purchaser could seek to (a) purchase
additional Shares in the open market or otherwise in order to reach the 90%
threshold and employ a short-form merger or (b) exercise its option to purchase
newly issued Shares pursuant to the Short Form Merger Option Agreement, dated as
of September 8, 1999, among Parent, Merger Sub and the Company (the "Short Form
Merger Option Agreement"). It is the Company's understanding that Parent
presently intends to effect a short-form merger, if permitted to do so under the
DGCL, pursuant to which Merger Sub will be merged with and into the Company.

         In connection with the Merger Agreement, Parent, Merger Sub and the
Company have entered into the Short Form Merger Option Agreement, pursuant to
which the Company granted to Merger Sub an irrevocable option to purchase from
the Company, at the Offer Price, newly issued Shares in an amount equal to the
number of Shares (up to a maximum of 19.9% of
<PAGE>   5
                                                                               5


the number of Shares outstanding) that, when added to the number of Shares owned
by Merger Sub and its affiliates immediately following consummation of the
Offer, constitutes 90% of the Shares then outstanding on a fully diluted basis
(giving effect to the issuance of such Shares). The option is exercisable at any
time after the acceptance for payment by Merger Sub of Shares in the Offer. For
a more detailed description of the short-form merger, reference is made to the
Short Form Merger Option Agreement included as Exhibit 2(b) to this Current
Report on Form 8-K.

         The Offer and the Merger are also subject to various other conditions,
including the Minimum Condition being satisfied, the receipt of all necessary
consents and approvals from the Company's and NovaCare's lenders, and the
expiration of the applicable waiting period under the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, if applicable. Subject to satisfaction of
these conditions and others, and assuming the Company will be able to effectuate
a short-form merger, it is expected that the Merger will be consummated sometime
in mid to late October 1999.

         For a more detailed description of the Merger and the Merger Agreement,
reference is made to the Merger Agreement included as Exhibit 2(a) to this
Current Report on Form 8-K.

                          AGREEMENT AND PLAN OF MERGER



                  AGREEMENT AND PLAN OF MERGER (this "Agreement"), dated as of

("Parent"), New Plato Acquisition, Inc., a Delaware corporation and a wholly
owned subsidiary of Parent ("Sub"), and NovaCare Employee Services, Inc., a
Delaware corporation (the "Company"). Capitalized terms used herein and not
defined in the specific Section in which they are used shall have the meanings
assigned to such terms in Article IX hereof.

                                    RECITALS

                  WHEREAS, the Board of Directors of each of Parent, Sub and the
Company has approved, and deems it advisable and in the best interests of its
respective stockholders to consummate, the acquisition of the Company by Parent
upon the terms and subject to the conditions set forth herein;

                  WHEREAS, in furtherance thereof, it is proposed that Parent
make a cash tender offer (the "Offer") to acquire any and all shares of the
issued and outstanding common stock, $0.01 par value, of the Company (referred
to herein as either the "Shares" or "Company Common Stock") for $2.50 per share,
net to the seller in cash or, in the alternative, at Parent's election, to
purchase Shares from NC Resources, Inc., a Delaware corporation and the holder
of record of 19,400,000 Shares of the Company ("Target Parent"), pursuant to the
Stockholder Agreement (as defined below) and thereafter to acquire the remaining
Shares pursuant to the Merger provided for herein; and

                  WHEREAS, also in furtherance of such acquisition, the Board of
Directors of each of Parent, Sub and the Company has approved this Agreement and
the Merger (as defined in Section 1.4 hereof) following the Offer in accordance
with the General Corporation Law of the State of Delaware (the "DGCL") and upon
the terms and subject to the conditions set forth herein; and

                  WHEREAS, the Board of Directors of the Company (the "Company
Board") has determined that the consideration to be paid for each Share in the
Offer and the Merger is fair to the holders of such Shares and has resolved to

                  NOW, THEREFORE, in consideration of the foregoing and the

Parent, Sub and the Company hereby agree as follows:

                                    ARTICLE I

                              THE OFFER AND MERGER

                  1.1 The Offer; Merger Election. (a) Within five business days
following the date hereof, Sub shall commence (within the meaning of Rule 14d-2
under the Securities Exchange Act of 1934, as amended (the "Exchange Act")) a
cash tender offer to acquire any and all Shares at a price of $2.50 per Share,
net to the seller in cash (such price, or such higher price per Share as may be
paid in the Offer, being referred to herein as the "Offer Price") and, subject
to there being validly tendered and not withdrawn prior to the expiration of the
Offer such number of Shares which, when added to the Shares, if any,
beneficially owned by Parent or Sub, would constitute a majority of the Shares
outstanding on a fully diluted basis (the "Minimum Condition") and to the other
conditions set forth in Annex A hereto (any of which may be waived in whole or
in part by Sub in its sole discretion), Sub shall, on the terms and subject to
the prior satisfaction or waiver of the conditions of the Offer, accept for
payment and pay for Shares tendered as soon as it is legally permitted to do so
under Applicable Law. The obligations of Sub to commence the Offer and to accept
for payment and to pay for any Shares validly tendered on or prior to the
expiration of the Offer and not withdrawn shall be subject only to the
conditions set forth in Annex A hereto. The Offer shall be made by means of an
offer to purchase (the "Offer to Purchase") containing the terms set forth in
this Agreement, the Minimum Condition and the conditions set forth in Annex A
hereto. Sub expressly reserves the right to amend any of the terms and
conditions of the Offer; provided, that Sub shall not without the prior written
consent of the Company (such consent to be authorized by the Company Board or a
duly authorized committee thereof) (i) decrease the Offer Price, (ii) decrease
the number of Shares sought, (iii) change the form of consideration to be paid
pursuant to the Offer, (iv) impose conditions to the Offer in addition to those
set forth in Annex A hereto, (v) amend any other term or condition of the Offer
in any manner adverse to the holders of the Shares or (vi) extend the expiration
date of the Offer. Notwithstanding the foregoing, Sub may, without the consent
of the Company, (A) extend the Offer, if at the initial scheduled or any
extended expiration date of the Offer any of the conditions of the Offer 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,


                                       2
<PAGE>   8
regulation, interpretation or position of the United States Securities and
Exchange Commission (the "SEC") or the staff thereof applicable to the Offer,
(C) extend the Offer for up to ten business days if there have not been validly
tendered and not withdrawn prior to the expiration of the Offer such number of
Shares that, together with Shares, if any, beneficially owned by Parent or Sub,
would constitute at least 90% of the fully diluted Shares as of the date of
determination, provided that all other conditions to the Offer are satisfied or
waived and (D) extend the Offer for any reason for up to two business days;
provided, that no more than three extensions in the aggregate shall be permitted
under clauses (C) and (D) of this sentence. In addition, the Offer Price may be
increased and the Offer may be extended to the extent required by law, in each
case without the consent of the Company.

                  (b) On the date the Offer is commenced, Parent and Sub shall
file with the SEC a Tender Offer Statement on Schedule 14D-1 with respect to the
Offer (together with all amendments and supplements thereto and including the
exhibits thereto, the "Schedule 14D-1"). The Schedule 14D-1 will include, as
exhibits, the Offer to Purchase and a form of letter of transmittal and summary
advertisement (collectively, together with any amendments and supplements
thereto, the "Offer Documents").

                  (c) Parent and Sub further agree to take all steps necessary
to cause the Offer Documents to be filed with the SEC and to be disseminated to
holders of Shares, in each case as and to the extent required by applicable
federal securities laws. Each of Parent and Sub, on the one hand, and the
Company, on the other hand, agrees promptly to correct any information provided
by it for use in the Offer Documents if and to the extent that it shall have
become false and misleading in any material respect and Parent and Sub further
agree to take all steps necessary to cause the Offer Documents as so corrected
to be filed with the SEC and 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 a reasonable opportunity to review the
Schedule 14D-1 and the Offer Documents before they are filed with the SEC. In
addition, Parent and Sub agree to provide the Company and its counsel in writing
with any comments, whether written or oral, that Parent, Sub or their counsel
may receive from time to time from the SEC or its staff with respect to the
Offer Documents promptly after the receipt of such comments or other
communications.

                  1.2 Company Actions.

                  (a) On the date the Offer Documents are filed with the SEC,
the Company shall file with the SEC a Solicitation/Recommendation Statement on
Schedule 14D-9 (together with all amendments and supplements thereto and
including the exhibits thereto, the "Schedule 14D-9") containing the
recommendation described in Section 3.21 hereof. At the time the Offer Documents
are first mailed to the stockholders of the Company, the Company shall mail or
cause to be mailed to the stockholders of the Company such Schedule 14D-9
together with such Offer Documents. The Company further agrees to take all steps
necessary to cause the Schedule 14D-9 to be disseminated to holders of Shares,
in each case as and to the extent required by applicable federal securities
laws. Each of the Company, on the one hand, and Parent and Sub, on the other
hand, agrees promptly to correct any information provided by it for use in the
Schedule 14D-9 if and to the extent that it shall have become false and
misleading in any material respect and the Company further agrees to take all
steps necessary to cause the Schedule 14D-9 as so corrected


                                       3
<PAGE>   9
to be filed with the SEC and to be disseminated to holders of the Shares, in
each case as and to the extent required by applicable federal securities laws.
Parent and its counsel shall be given a reasonable opportunity to review the
Schedule 14D-9 before it is filed with the SEC. In addition, the Company agrees
to provide Parent, Sub and their counsel in writing with any comments, whether
written or oral, that the Company or its counsel may receive from time to time
from the SEC or its staff with respect to the Schedule 14D-9 promptly after the
receipt of such comments or other communications.

                  (b) In connection with the Offer and the Merger, if requested
by Sub, the Company shall promptly furnish or cause to be furnished to Sub
mailing labels, security position listings and any available listing or computer
file containing the names and addresses of the record holders of the Shares as
of a recent date, and shall furnish Sub with such information and assistance as
Sub or its agents may reasonably request in communicating the Offer to the
stockholders of the Company. Except for such steps as are necessary to
disseminate the Offer Documents, Parent and Sub shall hold in confidence the
information contained in any of such labels and lists and the additional
information referred to in the preceding sentence, will use such information
only in connection with the Offer and the Merger, and, if this Agreement is
term-mated, will upon request of the Company deliver or cause to be delivered to
the Company all copies of such information then in its possession or the
possession of its agents or representatives.

                  1.3 Directors.

                  (a) Promptly upon the purchase of and payment for Shares by
Parent or any of its subsidiaries which represent at least a majority of the
then outstanding shares of Company Common Stock, Parent shall be entitled to
designate such number of directors, rounded up to the next whole number, on the
Company Board as is equal to the product of the total number of directors on the
Company Board (giving effect to the directors designated by Parent pursuant to
this sentence) multiplied by the percentage that the aggregate number of Shares
beneficially owned by Sub, Parent and any of their Affiliates (including Shares
so accepted for payment) bears to the total number of shares of Company Common
Stock then outstanding (on a fully diluted basis). The Company shall take all
action necessary to cause Parent's designees to be elected or appointed to the
Company Board and to secure the resignations of such number of its incumbent
directors as is necessary to enable Parent's designees to be so elected or
appointed. At such times, the Company will cause individuals designated by
Parent to constitute the same percentage (rounded up to the nearest whole
number) as such individuals represent on the Company Board of (A) each committee
of the Company Board and (B) each board of directors (and committee thereof) of
each Company Subsidiary (as defined in Section 3.1 hereof) in each case to the
extent permitted by Applicable Law or the rules or applicable listing agreement
of any stock exchange or over-the-counter market on which the Company Common
Stock is listed or traded. Notwithstanding the foregoing, until the Effective
Time (as defined in Section 1.5 hereof), the Company shall use its best efforts
to retain as members of the Company Board at least two directors that are
directors of the Company on the date hereof (the "Independent Directors");
provided, that subsequent to the purchase of and payment for Shares pursuant to
the Offer, Parent shall always have its designees represent at least a majority
of the entire Company Board. The Company's obligations under this Section 1.3(a)
shall be subject to Section 14(f) of the Exchange Act and Rule 14f-1 promulgated
thereunder. The Company shall promptly take all


                                       4
<PAGE>   10
actions required pursuant to such Section 14(f) and Rule l4f-1 in order to
fulfill its obligations under this Section 1.3(a), including mailing to
stockholders the information required by such Section 14(f) and Rule 14f-1 as is
necessary to enable Parent's designees to be elected or appointed to the Company
Board. Parent or Sub shall supply the Company any information with respect to
either of them and their nominees, officers, directors and affiliates required
by such Section 14(f) and Rule 14f-1. The provisions of this Section 1.3 are in
addition to and shall not limit any rights which Sub, Parent or any of their
Affiliates may have as a holder or beneficial owner of Shares as a matter of law
with respect to the election of directors or otherwise.

                  (b) In the event that Parent's designees are elected or
appointed to the Company Board, until the Effective Time, the Company shall use
its best efforts to maintain as members of the Company Board at least two
directors who are Independent Directors, provided that, in such event, if the
number of Independent Directors shall be reduced below two for any reason
whatsoever, the remaining Independent Director, if any, shall be entitled to
designate a person to fill such vacancy who shall be deemed to be an Independent
Director for purposes of this Agreement or, if no Independent Director then
remains, the other directors shall designate two persons to fill such vacancies
who shall not be stockholders, Affiliates or associates of Parent or Sub, and
each such person shall be deemed to be an Independent Director, for purposes of
this Agreement. Notwithstanding anything in this Agreement to the contrary, in
the event that Parent's designees constitute a majority of the directors on the
Company Board, the affirmative vote of a majority of the Independent Directors
shall be required after the acceptance for payment of Shares pursuant to the
Offer and prior to the Effective Time, to (a) amend or terminate this Agreement
by the Company, (b) exercise or waive any of the Company's rights, benefits or
remedies hereunder if such exercise or waiver materially and adversely affects
holders of Shares other than Parent or Sub, (c) take action with respect to the
retention of counsel and other advisors in connection with the transactions
contemplated hereby or (d) take any other action under or in connection with
this Agreement if such action materially and adversely affects holders of Shares
other than Parent or Sub; provided, that if there shall be no such directors,
such actions may be effected by unanimous vote of the entire Company Board. The
Independent Directors shall have the right to retain, at the expense of the
Company, one separate firm of counsel to represent them in connection with the
Transactions.

                  1.4 The Merger. Subject to the terms and conditions of this
Agreement, the Company and Sub shall consummate a merger (the "Merger") pursuant
to which (a) Sub shall be merged with and into the Company and the separate
corporate existence of Sub shall thereupon cease, (b) the Company shall be the
successor or surviving corporation in the Merger and shall continue to be
governed by the laws of the State of Delaware and (c) the separate corporate
existence of the Company with all its rights, privileges, immunities, powers and
franchises shall continue unaffected by the Merger. The corporation surviving
the Merger is sometimes hereinafter referred to as the "Surviving Corporation."
The Merger shall have the effects set forth in the DGCL.

                  1.5 Effective Time. Parent, Sub and the Company will cause a
Certificate of Merger (the "Certificate of Merger") to be executed and filed on
the date of the Closing (as defined in Section 1.6 hereof) (or on such other
date as Parent and the Company may agree) with the Secretary of State of the
State of Delaware (the "Secretary of State") as provided in the DGCL. The Merger
shall become effective at the time at which the Certificate of Merger has


                                       5
<PAGE>   11
been duly filed with the Secretary of State or at such time as is agreed upon by
the parties and specified in the Certificate of Merger, and such time is
hereinafter referred to as the "Effective Time."

                  1.6 Closing. The closing of the Merger (the "Closing") shall
take place at 10:00 a.m., local time, on a date to be specified by Parent or
Sub, which shall be no later than the second business day after the satisfaction
or waiver of all of the conditions set forth in Article VI hereof (the "Closing
Date") at the offices of Blank Rome Comisky & McCauley LLP, One Logan Square,
Philadelphia, Pennsylvania 19103, unless another date, time or place is agreed
to in writing by the parties hereto.

                  1.7 Certificate of Incorporation of the Surviving Corporation.
The Certificate of Incorporation of the Company, as in effect immediately prior
to the Effective Time, shall be the Certificate of Incorporation of the
Surviving Corporation until thereafter amended as provided by Applicable Law and
such Certificate of Incorporation.

                  1.8 By-Laws of the Surviving Corporation. The By-Laws of the
Company, as in effect immediately prior to the Effective Time, shall be the
By-Laws of the Surviving Corporation until thereafter amended as provided by
Applicable Law, the Certificate of Incorporation of the Surviving Corporation
and such By-Laws.

                  1.9 Directors and Officers of the Surviving Incorporation. The
directors of Sub at the Effective Time and the officers of the Company at the
Effective Time shall be the initial directors and officers, respectively, of the
Surviving Corporation until their respective successors have been duly elected
or appointed and qualified or until their earlier death, resignation or removal
in accordance with the Surviving Corporation's Certificate of Incorporation and
By-Laws.

                  1.10 Subsequent Actions. If at any time after the Effective
Time, the Surviving Corporation will consider or be advised that any deeds,
bills of sale, assignments, assurances or any other actions or things are
necessary or desirable to vest, perfect or confirm of record or otherwise in the
Surviving Corporation its right, title or interest in, to or under any of the
rights, properties or assets of either of the Company or Sub acquired or to be
acquired by the Surviving Corporation as a result of, or in connection with, the
Merger or otherwise to carry out this Agreement, the officers and directors of
the Surviving Corporation shall be authorized to execute and deliver, in the
name and on behalf of either the Company or Sub, all such deeds, bills of sale,
instruments of conveyance, assignments and assurances and to take and do, in the
name and on behalf of each of such corporations or otherwise, all such other
actions and things as may be necessary or desirable to vest, perfect or confirm

                  1.11 Stockholders' Meeting.

<PAGE>   12
                          (i) duly call, give notice of, convene and hold a
         special meeting of its stockholders (the "Special Meeting") as soon as
         practicable following the acceptance for payment and purchase of Shares
         by Sub pursuant to the Offer for the purpose of considering and taking
         action upon the approval of the Merger and the adoption of this
         Agreement;

                          (ii) prepare and file with the SEC a preliminary proxy
         or information statement relating to the Merger and this Agreement and
         shall obtain and furnish the information required to be included by the
         SEC in the Proxy Statement (as hereinafter defined) and, after
         consultation with Parent, to respond promptly to any comments made by
         the SEC with respect to the preliminary proxy or information statement
         and cause a definitive proxy or information statement, including any
         amendment or supplement thereto (the "Proxy Statement"), to be mailed
         to its stockholders, provided that no amendment or supplement to the
         Proxy Statement will be made by the Company without consultation with
         Parent and its counsel,

                          (iii) include in the Proxy Statement the
         recommendation of the Company Board that stockholders of the Company
         vote in favor of the approval of the Merger and the adoption of this
         Agreement; and

                          (iv) use its best efforts to solicit from holders of
         Shares proxies in favor of the Merger and shall take all other action
         necessary or, in the reasonable opinion of Parent, advisable to secure
         any vote or consent of stockholders required by the DGCL to effect the
         Merger.

                  (b) Parent agrees that it will provide the Company with the
information concerning Parent and Sub required to be included in the Proxy
Statement and will vote, or cause to be voted, all of the Shares then owned by
it, Sub or any of its other subsidiaries and Affiliates in favor of the approval
of the Merger and the adoption of this Agreement; provided that this Section
1.11(b) shall not apply to Shares held in any client or customer accounts over
which FMR Corp. or any of its Affiliates has investment management or advisory
responsibilities, including any of the Fidelity Investments mutual funds.

                  (c) The Company represents that the Proxy Statement (or any

therein, in light of the circumstances under which they are made, not
misleading, except that no representation is made by the Company with respect to

Effective Time, any event with respect to the Company, Stockholder or any of the
Company Subsidiaries should occur which is required to be described in a
supplement to the Proxy Statement, such event shall be so described, and such
supplement shall be promptly filed with the SEC and, as required by law,

                  1.12 Merger Without Meeting of Stockholders. Notwithstanding
Section 1.11 hereof, in the event that Parent, Sub or any other subsidiary of
Parent shall acquire in the aggregate a number of the outstanding Shares,
pursuant to the Offer or otherwise, sufficient to enable Sub or the Company to
cause the Merger to become effective under Applicable Law without a meeting of
stockholders of the Company, the parties hereto shall, at the request of Parent
and subject to Article VI hereof, take all necessary and appropriate action to
cause the Merger to become effective as soon as practicable after such
acquisition, without a meeting of stockholders of the Company, in accordance
with Section 253 of the DGCL.

                                   ARTICLE II

                            CONVERSION OF SECURITIES

                  2.1 Conversion of Capital Stock. As of the Effective Time, by
virtue of the Merger and without any action on the part of the holders of any
shares of Company Common Stock or common stock, par value $.01 per share, of Sub
("Sub Common Stock"):

                      (a) Sub Common Stock. Each issued and outstanding share of
Sub Common Stock shall be converted into and become one fully paid and
nonassessable share of common stock of the Surviving Corporation.

                      (b) Cancellation of Treasury Stock and Parent-Owned Stock.
All shares of Company Common Stock that are owned by the Company as treasury
stock and any shares of Company Common Stock owned by Parent, Sub or any other
wholly owned subsidiary of Parent shall be cancelled and retired and shall cease
to exist and no consideration shall be delivered in exchange therefor.

                      (c) Conversion of Shares. Each share of Company Common
Stock issued and outstanding (other than Shares to be cancelled in accordance
with Section 2.1 (b) hereof and Dissenting Shares (as defined in Section 2.4
hereof)), shall be converted into the right to receive the Offer Price, payable
to the holder thereof, without interest (the "Merger Consideration"), upon
surrender of the certificate formerly representing such share of Company Common
Stock in the manner provided in Section 2.2 hereof. All such shares of Company
Common Stock, when so converted, shall no longer be outstanding and shall
automatically be cancelled and retired 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
therefor, without interest, upon the surrender of such certificate in accordance
with Section 2.2 hereof or the right, if any, to receive payment from the
Surviving Corporation of the "fair value" of such Shares in accordance with
Section 262 of the DGCL.

                      (d) Stock Options. Information concerning outstanding
stock options to purchase Shares ("Options") granted under the Company's stock
option plans and agreements (the "Option Plans") (including the names of the
optionees, the dates of grant, the number of shares subject to such options and
the exercise prices of such options) is set forth in Section 2.1(d) of the
disclosure schedule delivered to Parent and Sub by the Company concurrently with
the execution hereof (the "Company Disclosure Schedule"). In consideration for
the cancellation of the outstanding "in the money" Options pursuant to this
Section 2.1(d),


                                       8
<PAGE>   14
the Company shall pay to the holders of such Options an amount, in cash, equal
to the product of (A) the difference between the Offer Price and the per share
exercise price of such Options multiplied by (B) the number of Shares covered by
such Options. The Company agrees that with respect to all outstanding
"underwater" Options, the Company shall, prior to completion of the Offer,
obtain agreements from the holders of Options who are senior management,
executive officers, and/or directors of the Company and the officers and
directors of Ultimate Parent deemed to have been founders of the Company, as set
forth in Section 2.1(d) of the Company Disclosure Schedule, to cancel their
Options and shall use its best efforts to obtain agreements from all other
holders of Options to cancel their Options, and, after such cancellation
pursuant to this Section 2.1(d), there shall be outstanding no more than an
aggregate of underwater Options to purchase 75,000 shares held by such other
holders of Options.

                  2.2 Exchange of Certificates.

                      (a) Paying Agent. Parent shall designate a bank or trust
company reasonably acceptable to the Company to act as agent for the holders of
shares of Company Common Stock in connection with the Merger (the "Paying
Agent") to receive the funds to which holders of shares of Company Common Stock
shall become entitled pursuant to Section 2.1(c) hereof. Parent shall, from time
to time, make available to the Paying Agent funds in amounts and at times
necessary for the payment of the Merger Consideration as provided herein. Such
funds shall be invested by the Paying Agent as directed by Parent. Earnings from
such investments shall be the sole and exclusive property of Parent, and no part
of such earnings shall accrue to the benefit of holders of Shares.

                      (b) Exchange Procedures. As soon as reasonably
practicable, but in no event more than five business days, after the Effective
Time, Parent shall cause the Paying Agent to mail to each holder of record of a
certificate or certificates, which immediately prior to the Effective Time
represented outstanding shares of Company Common Stock (the "Certificates"),
whose shares were converted pursuant to Section 2.1 hereof into the right to
receive the Merger Consideration (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 such form and have such other provisions not inconsistent
with this Agreement as Parent may reasonably specify) and (ii) instructions for
use of such letter of transmittal in effecting the surrender of the Certificates
in exchange for payment of 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, the holder of such Certificate shall be entitled to receive in
exchange therefor the Merger Consideration for each share of Company Common
Stock formerly represented by such Certificate and the Certificate so
surrendered shall forthwith be cancelled. If payment of the Merger Consideration
is to be made to a person other than the person in whose name the surrendered
Certificate is registered, it shall be a condition of payment that the
Certificate so surrendered shall be properly endorsed or shall be otherwise in
proper form for transfer and that the person requesting such payment shall have
paid any transfer and other taxes required by reason of the payment of the
Merger Consideration to a person other than the registered holder of the
Certificate surrendered or shall have established to the satisfaction of the
Surviving Corporation that such tax either has been paid or is not applicable.
Until surrendered as contemplated by this Section 2.2, each Certificate shall be
deemed at any time after the Effective

Time to represent only the right to receive the Merger Consideration in cash as
contemplated by this Section 2.2. No interest shall be paid or will accrue on
the Merger Consideration payable to holders of Certificates pursuant to the
provisions of this Article II.

                      (c) Transfer Books; No Further Ownership Rights in Company
Common Stock. At the Effective Time, the stock transfer books of the Company
shall be closed and thereafter there shall be no further registration of
transfers of shares of Company Common Stock on the records of the Company. From
and after the Effective Time, the holders of Certificates evidencing ownership
of shares of Company Common Stock outstanding immediately prior to the Effective
Time shall cease to have any rights with respect to such Shares, except as
otherwise provided for herein or by Applicable Law. If, after the Effective
Time, Certificates are presented to the Surviving Corporation for any reason,
they shall be cancelled and exchanged as provided in this Article II.

                      (d) Termination of Fund, No Liability. At any time
following six months after the Effective Time, the Surviving Corporation shall
be entitled to require the Paying Agent to deliver to it any funds (including
any interest received with respect thereto) which had been made available to the
Paying Agent and which have not been disbursed to holders of Certificates, and
thereafter such holders shall be entitled to look to the Surviving Corporation
(subject to abandoned property, escheat or other similar laws) only as general
creditors thereof with respect to the Merger Consideration payable upon due
surrender of their Certificates, without any interest thereon. Notwithstanding
the foregoing, none of Parent, the Surviving Corporation or the Paying Agent
shall be liable to any holder of a Certificate for Merger Consideration
delivered to a public official pursuant to any applicable abandoned property,
escheat or similar law.

                      (e) Lost Certificates. If any Certificate shall have been
lost, stolen or destroyed, upon the making of an affidavit of that fact by the
person claiming such Certificate to be lost, stolen or destroyed with such
assurances as the Paying Agent may, in its discretion require, and, if required
by the Surviving Corporation, the posting by such person of a bond in such
reasonable amount as the Surviving Corporation may direct as indemnity against
any claim that may be made against it with respect to such Certificate, the
Paying Agent shall pay in exchange for such lost, stolen or destroyed
Certificates the Merger Consideration pursuant to this Agreement.

                  2.3 Withholding Taxes. Parent and Sub shall be entitled to
deduct and withhold, or cause the Paying Agent to deduct and withhold, from the
Offer Price or the Merger Consideration payable to a holder of Shares pursuant
to the Offer or the Merger any withholding and stock transfer Taxes (as defined
in Section 3.8 hereof) and such amounts as are required under the Code or any
applicable provision of state, local or foreign Tax law. To the extent that
amounts are so withheld by Parent or Sub, such withheld amounts shall be treated
for all purposes of this Agreement as having been paid to the holder of the
Shares in respect of which such deduction and withholding was made by Parent or
Sub.

                  2.4 Appraisal Rights. Notwithstanding anything in this
Agreement to the contrary, Shares (the "Dissenting Shares") that are issued and
outstanding immediately prior to the Effective Time and which are held by
stockholders who did not vote in favor of the Merger


                                       10
<PAGE>   16
and who comply with all of the relevant provisions of Section 262 of the DGCL
(the "Dissenting Stockholders") shall not be converted into or be exchangeable
for the right to receive the Merger Consideration, unless and until such holders
shall have failed to perfect or shall have effectively withdrawn or lost their
rights to appraisal under the DGCL, but the holders thereof shall be entitled to
only such rights as are granted by the DGCL. If any Dissenting Stockholder shall
have failed to perfect or shall have effectively withdrawn or lost such right,
such holder's Shares shall thereupon be converted into and become exchangeable
for the right to receive, as of the Effective Time, the Merger Consideration
without any interest thereon, upon surrender of the Certificate or Certificates
representing such Shares pursuant to Section 2.2 hereof. The Company shall give
Parent (i) prompt notice of any written demands for appraisal of any Shares,
attempted withdrawals of such demands and any other instruments served pursuant
to the DGCL and received by the Company relating to the stockholders' rights of
appraisal and (ii) the opportunity to direct all negotiations and proceedings
with respect to demands for appraisal under the DGCL. Neither the Company nor
the Surviving Corporation shall, except with the prior written consent of
Parent, voluntarily make any payment with respect to, or settle or offer to
settle, any such demand for payment. If any Dissenting Stockholder shall fail to
perfect or shall have effectively withdrawn or lost the right to dissent, the
Shares held by such Dissenting Stockholder shall thereupon be treated as though
such Shares had been converted into the right to receive the Merger
Consideration pursuant to Section 2.1 (c) hereof.

                                   ARTICLE III

                         REPRESENTATIONS AND WARRANTIES
                                 OF THE COMPANY

                  The Company hereby represents and warrants to Parent and Sub
as follows:

                  3.1 Organization and Qualification; Company Subsidiaries. The
Company and each of its subsidiaries (each a "Company Subsidiary" and
collectively, the "Company Subsidiaries") is validly existing and in good
standing under the laws of the jurisdiction of its organization, and has all
requisite corporate or partnership (as applicable) power, authority and legal
right to own, operate and lease its assets and properties and to conduct the
businesses in which it is now engaged. The Company and each Company Subsidiary
is duly qualified and in good standing to transact business as a foreign
corporation or limited partnership (as applicable) in all jurisdictions wherein
it is required to be so qualified, except where the failure to be so qualified
would not have, individually or in the aggregate, a Company Material Adverse
Effect. Neither the Company nor any Company Subsidiary conducts business in any
jurisdiction outside of the United States. The Company does not have any
subsidiaries other than the Company Subsidiaries listed in Section 3.1 of the
Company Disclosure Schedule. Except as set forth in Section 3.1 of the Company
Disclosure Schedule, the Company, directly or indirectly through a wholly owned
Company Subsidiary, owns of record and beneficially all of the issued and
outstanding shares of capital stock of each Company Subsidiary, free and clear
of all Liens. Other than the Company Subsidiaries and other than as set forth in
Section 3.1 of the Company Disclosure Schedule, the Company does not own any
capital stock or other proprietary interest, directly or indirectly, in any
corporation, association, trust, partnership, joint venture, limited liability
company or other entity nor is the Company bound by any agreement to acquire any
such capital stock or other proprietary interest. Copies of the Certificate of
Incorporation and


                                       11
<PAGE>   17
By-Laws of the Company and each Company Subsidiary which is a corporation and
copies of the Certificate of Limited Partnership and Agreement of Limited
Partnership of each Company Subsidiary which is a limited partnership have been
heretofore made available to Parent and Sub, which copies are complete and
correct and include all amendments, modifications or supplements thereto.

                  3.2 Conflicts. Neither the execution, delivery or performance
of this Agreement or the Stock Option Agreement by the Company, nor the
consummation of the Transactions contemplated hereby or thereby to be
consummated by the Company, (a) violates any provision of the Certificate of
Incorporation or By-Laws or other organizational documents of the Company or any
Company Subsidiary or (b) constitutes a violation of any Applicable Law. Except
as set forth in Section 3.2 of the Company Disclosure Schedule, neither the
execution, delivery or performance of this Agreement or the Stock Option
Agreement by the Company nor the consummation of the Transactions contemplated
hereby or thereby to be consummated by the Company, with or without notice
and/or lapse of time, (i) violates, conflicts with, results in any breach of any
of the terms of, or results in the termination or modification of, or the
exercise or acceleration of any right or remedy under, any Company Material
Contract (as defined in Section 3.10 hereof), any other contract of the Company
or any Company Subsidiary, or other obligation to which the Company or any
Company Subsidiary is subject, (ii) violates, conflicts with, results in any
breach of any of the terms of, or results in the termination, modification or
revocation of, any Permit held by the Company or any Company Subsidiary, or
(iii) results in the creation of any Lien on any of the assets or properties
owned or used by the Company or any Company Subsidiary, except where such
violation, conflict, breach, termination or Lien would not have, individually or
in the aggregate, a Company Material Adverse Effect.

                  3.3 Capitalization. The authorized capital stock of the
Company consists of: (i) 60,000,000 Shares, of which, as of the date hereof,
30,274,000 Shares were issued and outstanding and (ii) 1,000,000 shares of
preferred stock, $0.01 par value per share, none of which, as of the date
hereof, were issued and outstanding. As of the date hereof, 2,271,250 Shares
were reserved for issuance upon exercise of outstanding Options under the 1997

exercise of outstanding Options and as earn-out payments pursuant to the
Acquisition Agreements, will be, when so issued, duly authorized, validly
issued, fully paid and nonassessable and not subject to preemptive rights. There
are no bonds, debentures, notes or other indebtedness or securities of the
Company or of any Company Subsidiary issued and outstanding which have the right

Company Subsidiary may vote. Except as set forth above or in Section 2.1(d) of
the Company Disclosure Schedule and except for a maximum of 6,124,000 Shares

securities of the Company are issued, reserved for issuance or outstanding, (ii)
there are no stock appreciation rights, phantom stock units, restricted stock
grants, contingent stock grants or Benefit Plans (as defined in Section 3.11
hereof) which grant awards of any of the foregoing, and there are no other
outstanding contractual rights to which the Company is a party the value of
which is based on the value of Shares; and (iii) except as set forth above,
there are no outstanding securities, options, warrants, calls, rights,
commitments, agreements, arrangements or undertakings of any kind to which the
Company or any Company Subsidiary is a party or by which any of them is bound

cause to be issued, delivered or sold, shares of capital stock or other
securities of the Company or of any Company Subsidiary or obligating the Company
or any Company Subsidiary to issue, grant, extend or enter into any such

Schedule, there are no programs in place, nor any outstanding contractual
obligations of the Company or any Company Subsidiary, to repurchase, redeem or
otherwise acquire any shares of capital stock or other equity securities of the
Company or any Company Subsidiary or to provide funds to make any investment (in
the form of a loan, capital contribution or otherwise) in any Company Subsidiary
or any other entity. There are no voting trusts or other agreements or
understandings to which the Company or any Company Subsidiary is a party with
respect to the voting of the capital stock or other equity securities of the
Company or any Company Subsidiary. Except as set forth in Section 3.3 of the
Company Disclosure Schedule, no indebtedness of the Company or any Company
Subsidiary or as to which the Company or any Company Subsidiary has given a
guarantee or by which any of their respective assets or properties are bound
contains any restriction upon (i) the prepayment of any indebtedness of the

Subsidiary that is wholly owned by the Company, free and clear of all Liens.

                  3.4 SEC Reports: Financial Statements; Undisclosed
Liabilities.

                      (a) The Company has filed all forms, reports, schedules,
statements and other documents required to be filed by it with the SEC since its
inception pursuant to the federal securities laws and the SEC rules and
regulations thereunder, all of which, as of their respective dates, complied in
all material respects with applicable requirements of the Securities Act of
1933, as amended (the "Securities Act"), and the Exchange Act, as the case may
be, and the applicable rules and regulations of the SEC thereunder
(collectively, the "Company SEC Reports"). None of the Company SEC Reports,
including, without limitation, any financial statements or schedules included
therein, as of their respective dates, contained any untrue statement of a
material fact or omitted to state a 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.

                      (b) The financial statements (including the related notes
thereto) of the Company included in the Company SEC Reports comply in all
material respects with applicable


                                       13
<PAGE>   19
accounting requirements and the published rules and regulations of the SEC with
respect thereto, have been prepared in conformity with generally accepted
accounting principles ("GAAP") in the United States applied on a consistent
basis during the periods involved (except as otherwise noted therein), and
present fairly the consolidated financial position of the Company and its
consolidated Company Subsidiaries as of their respective dates, and the
consolidated results of their operations and cash flows for the periods
presented therein (subject, in the case of the unaudited interim financial
statements, to normal year-end adjustments).

                      (c) Except (i) as set forth in Section 3.4(c) of the
Company Disclosure Schedule, (ii) as set forth in the consolidated balance sheet
of the Company as of March 31, 1999 set forth in the Company's Quarterly Report
on Form 10-Q for the quarter ended March 31, 1999 (the "Balance Sheet") and
(iii) for current liabilities and obligations incurred in the ordinary course of
business consistent with past practice since March 31, 1999 (and not materially
different in type or amount), neither the Company nor any Company Subsidiary has
any material liabilities or obligations of any nature (whether accrued,
absolute, contingent or otherwise).

                      (d) All accounts receivable of the Company and each
Company Subsidiary that are reflected in the Balance Sheet or on the accounting
records of the Company and the Company Subsidiaries as of the date any Shares
have been accepted for payment pursuant to the Offer represent and will
represent valid obligations arising from sales actually made or services
actually performed in the ordinary course of business. Section 3.4(d) of the
Company Disclosure Schedule contains a complete and accurate aged accounts
receivable list of the Company and the Company Subsidiaries as of June 30, 1999.
As of the date any Shares have been accepted for payment pursuant to the Offer,
there shall have been no material increase in the accounts receivable of the
Company and the Company Subsidiaries that are 30 days or more past due. Unless
paid prior to the date any Shares have been accepted for payment pursuant to the
Offer, the accounts receivable of the Company and each Company Subsidiary are or
will be as of the date any Shares have been accepted for payment pursuant to the
Offer, collectible net of the respective reserves shown in Section 3.4(d) of the
Company Disclosure Schedule or on the accounting records of the Company and each
Company Subsidiary as of the date any Shares have been accepted for payment
pursuant to the Offer (which reserves are adequate and calculated consistent
with past practice and, in the case of the reserves as of the date any Shares
have been accepted for payment pursuant to the Offer, will not represent a
greater percentage of the 30 days or more past due accounts receivable as of
such date than the reserves reflected in Section 3.4(d) of the Company
Disclosure Schedule represented of such past due accounts receivable reflected
therein).

                  3.5 Schedule 14D-9; Offer Documents; Proxy Statement. Neither
the Schedule 14D-9, any other document required to be filed by the Company with
the SEC in connection with the Transactions, nor any information supplied by the
Company for inclusion in the Offer Documents shall, at the respective times the
Schedule 14D-9, any such other filings by the Company, the Offer Documents or
any amendments or supplements thereto are filed with the SEC or are first
published, sent or given to stockholders of the Company, as the case may be,
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
made therein, in light of the circumstances under which they are made, not
misleading. The Proxy Statement, if any, will not, on the date the Proxy
Statement (including any amendment or supplement thereto) is first mailed


                                       14
<PAGE>   20
to stockholders of the Company and at the time of the Special Meeting, contain
any untrue statement of a material fact, or omit to state any material fact
required to be stated therein or necessary in order to make the statements made
therein, in light of the circumstances under which they are made, not misleading
and the Proxy Statement will not, at the time of the Special Meeting, omit to
state any material fact necessary to correct any statement in any earlier
communication with respect to the solicitation of proxies for the Special
Meeting which shall have become false or misleading in any material respect. The
Schedule 14D-9, any other document required to be filed by the Company with the
SEC in connection with the Transactions, and the Proxy Statement will, when
filed by the Company with the SEC, comply as to form in all material respects
with the applicable provisions of the Exchange Act and the rules and regulations
thereunder. Notwithstanding the foregoing, the Company makes no representation
or warranty with respect to the statements made in any of the foregoing
documents based on and in conformity with information supplied in writing by or
on behalf of Parent or Sub specifically for inclusion therein.

                 3.6 Absence of Certain Changes. Except as set forth in Section
3.6 of the Company Disclosure Schedule or in the Company SEC Reports, since the
date of the Balance Sheet, (i) the Company and each Company Subsidiary has
conducted its respective business in all material respects in the ordinary and
usual course consistent with past practice, (ii) there has not occurred any
events or changes (including the incurrence of any liabilities of any nature,
whether or not accrued, contingent or otherwise) having or reasonably likely to
have, individually or in the aggregate, a Company Material Adverse Effect, and
(iii) neither the Company nor any Company Subsidiary has taken any action that
would have been prohibited by Section 5.1 if such section applied to the period
between the date of the Balance Sheet and the date hereof.

                  3.7 Taxes. Except as set forth in Section 3.7 of the Company
Disclosure Schedule:

license, transfer, capital, net worth, gains, excise, social security and
workers' compensation taxes and estimated income and franchise tax payments, and
penalties, interest and fines with respect to any thereof) (collectively,
"Taxes") due and payable by it. Since their respective dates of acquisition, the
taxable income of the Company and each Company Subsidiary has been included in
the consolidated federal income Tax Returns of the Company to the extent
required to be included under the Code and in the consolidated, combined or
unitary state income Tax Returns of the Company to the extent required to be
included under applicable state income Tax rules.

                      (b) With respect to any Taxes of the Company or any
Company Subsidiary not yet due and payable, adequate reserves and accruals for
such Taxes have been made in the Financial Statements or in the books and

received written notice from any taxing authority of any material deficiency,
claim or other dispute relating to the payment or assessment of any Taxes for

Subsidiary.

                      (j) The Company has delivered or caused to be delivered to

severance contracts or agreements with officers or key employees of the Company
and each Company Subsidiary and all agreements or arrangements that provide for
any payment by the Company or any Company Subsidiary upon a change of control
(all contracts of the type described in clauses (i) - (x) whether existing as of
the date hereof or entered into at any time between the date hereof and the
Closing being referred to herein as "Company Material Contracts"). Each Company
Material Contract is valid and binding on the Company (or, to the extent a
Company Subsidiary is a party, such Company Subsidiary) and is in full force and
effect, and the Company and Company Subsidiary have performed in all material
respects all obligations required to be performed by them to date under each
Company Material Contract. Neither the Company nor any Company Subsidiary knows
of, or has received notice of, any violation or default under (nor, to the
knowledge of the Company, does there exist any condition which with the passage
of time or the giving of notice or both would result in such a violation or
default under) any Company Material Contract by either the Company or a Company
Subsidiary, as the case may be, or any other party to a Company Material
Contract, except for violations or defaults which would not, individually or in
the aggregate, result in a Company Material Adverse Effect. Originals or true,
correct and complete copies of all Company Material Contracts have been provided
or made available to Parent. The Company has delivered to Parent the standard
forms of agreement used by the Company and the Company Subsidiaries for the
provision of professional employer services, and, except for the agreements
entered into with Ultimate Parent, Hanger Orthopedic Group, Inc., and The Boston
Financial Group Limited Partnership, each agreement entered into by the Company
or a Company Subsidiary (during such time as it was a Company Subsidiary) with a
subscriber for the provision of such services is substantially the same as one
of the standard forms of agreement. The Company has sent a Notice of Termination
to the shareholders of Unified Management Corporation and its affiliated
corporations (collectively, "Unified") notifying Unified and the shareholders of
Unified of the Company's termination of the Agreement of Purchase and Sale dated
as of June 16, 1999 by and among Unified, the shareholders of Unified and the
Company.

                    REPRESENTATIONS AND WARRANTIES OF PARENT
                                     AND SUB

                  Each of Parent and Sub represents and warrants, jointly and
severally, to the Company that:

                  4.1 Organization and Qualification. Each of Parent and Sub is
a corporation, duly organized, validly existing and in good standing under the
laws of its respective jurisdiction of organization. Each of Parent and Sub is
qualified and in good standing as a foreign corporation, in each jurisdiction
where the properties owned, leased or operated, or the business conducted, by it
require such qualification, except where the failure to so qualify or be in good
standing would not materially impair or delay the ability of Parent or Sub to
consummate the Transactions (a "Parent Material Adverse Effect").

                  4.2 Authority. Each of Parent and Sub has the requisite
corporate power and authority to execute and deliver this Agreement and the
Stock Option Agreement and to consummate the transactions contemplated hereby
and thereby. The execution, delivery and performance of this Agreement and the
Stock Option Agreement and the consummation by Parent and Sub of the
Transactions have been duly and validly authorized by the Board of


                                       26
<PAGE>   32
Directors of each of Parent and Sub and by Parent as the sole stockholder of
Sub, and no other corporate action on the part of Parent and Sub is necessary to
authorize this Agreement or the Stock Option Agreement or to consummate the
Transactions. This Agreement and the Stock Option Agreement have been duly and
validly executed and delivered by each of Parent and Sub and, assuming this
Agreement and the Stock Option Agreement constitute the valid and binding
agreements of the Company, constitute the valid and binding agreements of each
of Parent and Sub, enforceable against each of them in accordance with its
terms, except that the enforcement hereof or thereof may be limited by (a)
bankruptcy, insolvency, reorganization, moratorium or other similar laws now or
hereafter in effect relating to creditors' rights generally and (b) general
principles of equity (regardless of whether enforceability is considered in a
proceeding at law or in equity).

                  4.3 Consents and Approvals; No Violation.

                      (a) Except as set forth in Section 4.3(a) of the
disclosure schedule delivered to the Company by Parent concurrently with the
execution hereof (the "Parent Disclosure Schedule"), neither the execution,
delivery and performance of this Agreement or the Stock Option Agreement by
Parent or Sub nor the consummation by Parent or Sub of the Transactions
contemplated hereby or thereby to be consummated by Parent or Sub will require
any consent, approval, authorization or permit of, or filing with or
notification to, any Governmental Entity, other than (A) in connection with the
applicable requirements of the HSR Act, (B) pursuant to the applicable
requirements of the Exchange Act, (C) the filing of the Certificate of Merger
pursuant to the DGCL and appropriate documents with the relevant authorities of
other states in which Parent or Sub is authorized to do business, or (D) as may
be required by any applicable state corporation, securities or "blue sky" laws
or state takeover laws. Parent will use its reasonable best efforts to obtain
and deliver to the Company executed counterpart copies of all consents referred
to in the preceding sentence prior to consummation of the Offer.

                      (b) Neither the execution, delivery and performance of
this Agreement or the Stock Option Agreement by Parent or Sub nor the
consummation by Parent or Sub of the Transactions will (i) conflict with or
result in any breach of any provision of the Certificate of Incorporation or the
By-Laws of either Parent or Sub; (ii) subject to obtaining the required third
party consents set forth in Section 4.3(a) of the Parent Disclosure Schedule,
result in 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,
cancellation or acceleration or Lien or other charge or encumbrance) under any
of the terms, conditions or provisions of any note, license, agreement or other
instrument or obligation to which Parent or Sub is a party or by which either of
them or any of their respective assets may be bound; or (iii) assuming the
consents, approvals, authorizations or permits and filings or notifications
referred to in Section 4.3(a) hereof are duly and timely obtained or made,
violate any order, writ, injunction, decree, statute, rule or regulation in
effect as of the date of this Agreement and applicable to Parent or Sub or any
of their respective assets, excluding from the foregoing clauses (ii) and (iii)
such violations, breaches or defaults (or rights of termination, cancellation or
acceleration or Liens or other charges or encumbrances) which would not,
individually or in the aggregate, have a Parent Material Adverse Effect.

                  4.4 Interim Operations of Sub. Sub was formed solely for the
purpose of engaging in the Transactions and has not engaged in any business
activities or conducted any operations other than in connection with the
Transactions.

                  4.5 Financing. As of the date hereof and at the expiration of
the Offer and at the Effective Time, either Parent or Sub has and will have
available all the funds, or has written binding commitments from financial
institutions or other sources to obtain all the funds, necessary to purchase all
of the Shares pursuant to the Offer and the Merger and to pay all fees, expenses
and payments payable by Parent or Sub related to the Transactions.

                  4.6 Share Ownership. Except for shares owned by Affiliates of
FMR Corp. in the ordinary course of business, none of Parent, Sub nor any of
their respective "affiliates" or "associates" (as such terms are defined in Rule
12b-2 under the Exchange Act) beneficially owns any Shares.

                  4.7 Information in Proxy Statement and Schedule 14D-9. None of
the information supplied by Parent or Sub for inclusion or incorporation by
reference in the Proxy Statement or the Schedule 14D-9 will, at the date mailed
to stockholders and at the time of the Special Meeting, contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary in order to make the statements therein, in light of
the circumstances under which they are made, not misleading. If at any time
prior to the Effective Time any event with respect to Parent or Sub should occur
which is required to be described in a supplement to the Proxy Statement or the
Schedule 14D-9, such event shall be so described, and such supplement shall be
promptly filed with the SEC and, as required by law, disseminated to the
stockholders of the Company. With respect to information relating to Parent or
Sub, the Proxy Statement will comply in all material respects with the
provisions of the Exchange Act and the rules and regulations thereunder.

                  4.8 Brokers and Finders. Parent and Sub have not employed any
investment banker, broker, finder, advisor, consultant or intermediary in
connection with the Transactions which would be entitled to any investment
banking, brokerage, finder's, advisory or similar fee or commission in
connection with this Agreement, or the Stock Option Agreement or the
Transactions.

indirectly, solicit, initiate or encourage any inquiry, proposal or offer, or
participate in or initiate discussions or negotiations with, or provide any
information to, any person or group (other than Parent, any of its Affiliates or
representatives), concerning any proposal or offer for a merger, share exchange,
consolidation, recapitalization, asset acquisition or other business combination
or similar transaction involving the Company or any Company Subsidiary or any
proposal or offer to acquire an equity interest representing 20% or more of the
outstanding Common Stock or voting power in, or 20% or more of the fair market
value of the assets of, the Company or any Company Subsidiary other than the
Transactions (an "Alternative Proposal"), or otherwise cooperate in any way
with, or participate in, facilitate or actively encourage any effort or attempt
by, any person or group (other than Parent, any of its Affiliates or
representatives) to do or seek any of the foregoing, except that nothing
contained in this Section 5.2 or any other provision hereof shall prior to the
time of acceptance of Shares for payment pursuant to the Offer prohibit the
Company or the Company Board from (i) taking and disclosing to the Company's
stockholders a position with respect to a tender or exchange offer by a third
party pursuant to Rules 14d-9 and 14e-2 promulgated under the Exchange Act, or
(ii) making such disclosure to the Company's stockholders as, in the good faith
judgment of the Company Board, after receiving advice from outside counsel, is
required under Applicable Law, provided that the Company may not, except as
permitted by Section 5.2(b) hereof, withdraw or modify, or propose to withdraw
or modify, its position with respect to the Offer or the Merger or approve or
recommend, or propose to approve or recommend, any Alternative Proposal, or
enter into any letter of intent, agreement in principle or definitive agreement
with respect to any Alternative Proposal. Upon execution of this Agreement, the
Company will immediately cease any existing activities, discussions or
negotiations with any parties conducted heretofore with respect to any of the
foregoing. Notwithstanding the foregoing, prior to the time of acceptance of
Shares for payment pursuant to the Offer, the Company may, subject to providing
prior written notice to Parent of its decision to take such action, furnish
information concerning its business, properties or assets to any corporation,
partnership, person or other entity or group in response to a Superior Proposal
that is submitted by such entity or group, and may, subject to providing prior
written notice to Parent of its decision to take such action, negotiate and
participate in discussions and negotiations with such entity or group concerning
a Superior Proposal (as defined below) if (A) such entity or group has on an
unsolicited basis submitted a bona fide written proposal to the Company Board to
acquire more than a majority of the Shares then outstanding on a fully diluted
basis or all or substantially all of the assets of the Company, which the
Company Board determines in good faith, based on the written advice of the
Company's financial advisors, to be more favorable from a financial point of
view to the Company's stockholders than the Offer and the Merger, and which is
neither subject to the receipt of any necessary financing nor otherwise on terms
less favorable than the terms hereof and which in the opinion of the Company
Board, based on the written advice of the Company's financial advisors, such
entity or group has the financial capacity to consummate (a "Superior
Proposal"), (B) the Company Board believes in good faith, based on the advice of
its outside legal counsel, that such action is reasonably necessary in order for
the Company Board to comply with its fiduciary obligations to the Company's
stockholders under Applicable Law, (C) the Company furnishes such information to

                                       32
<PAGE>   38
such entity or group pursuant to an appropriate confidentiality agreement on
terms no less favorable to the Company than the Confidentiality Agreement, and
(D) neither the Company nor any Company Subsidiary or Affiliate, nor any of
their respective officers, directors, employees, representatives or agents,
shall have violated any of the restrictions set forth in this Section 5.2.

                  The Company will immediately notify Parent of the existence of
any proposal, discussion, negotiation or inquiry received by the Company, and
the Company will immediately communicate to Parent the terms of any proposal,
discussion, negotiation or inquiry which it may receive (and will immediately
provide to Parent copies of any written materials received by the Company in
connection with such proposal, discussion, negotiation or inquiry) and the
identity of the party making such proposal or inquiry or engaging in such
discussion or negotiation. The Company will promptly provide to Parent any
non-public information concerning the Company provided to any other party which
was not previously provided to Parent.

                           (b) Except as set forth below in this subsection (b),
neither the Company Board nor any committee thereof shall (i) withdraw or
modify, or propose to withdraw or modify, in a manner adverse to Parent or Sub,
the approval or recommendation by the Company Board or any such committee of the
Offer, this Agreement or the Merger, (ii) approve or recommend or propose to
approve or recommend, any Alternative Proposal or (iii) cause the Company to
enter into any letter of intent, agreement in principle or definitive agreement
with respect to any Alternative Proposal. Notwithstanding the foregoing, prior
to the time of acceptance for payment of Shares pursuant to the Offer, the
Company Board may withdraw or modify its approval or recommendation of the
Offer, this Agreement or the Merger if (A) the Company has received a Superior
Proposal which is then pending and which the Company Board has determined to
recommend to the Company's stockholders, (B) the Company Board concludes, in
good faith, based on the advice of its outside legal counsel, that in light of
such Superior Proposal, the withdrawal or modification of such approval or
recommendation is reasonably necessary in order for the Company Board to comply
with its fiduciary obligations to the Company's stockholders under Applicable
Law, (C) the Company notifies Parent at least five business days prior to taking
any action with respect to such Superior Proposal or the withdrawal or
modification of its approval or recommendation, specifying the material terms
and conditions of such Superior Proposal, and identifying the person making such
Superior Proposal; and (D) the Company gives Parent at least five business days
after the Company gives notice to Parent pursuant to clause (C) to match or
better such Superior Proposal and Parent fails to or decides not to do so within
such five-day period.

                  5.3      Reasonable Best Efforts.

                           (a) Prior to the Closing, upon the terms and subject
to the conditions of this Agreement, Parent, Sub and the Company agree to use
their respective reasonable best efforts (x) to take, or cause to be taken, all
actions, and (y) to do, or cause to be done, all things necessary, proper or
advisable (subject to any Applicable Laws) to consummate and make effective the
Merger and the other Transactions as promptly as practicable including, but not
limited to (i) the preparation and filing of all forms, registrations and
notices required to be filed to consummate the Merger and the other Transactions
and the taking of such actions as are necessary to obtain any requisite
approvals, consents, orders, exemptions or waivers by any third party or
Governmental Entity, (ii) the preparation of any disclosure documents reasonably

                                       33
<PAGE>   39
requested by Parent in order to facilitate financing of any of the Transactions
and (iii) the satisfaction of the other parties' conditions to Closing. In
addition, no party hereto shall take any action after the date hereof that would
reasonably be expected to delay materially the obtaining of, or result in not
obtaining, any permission, approval or consent from any Governmental Entity
necessary to be obtained prior to Closing. Notwithstanding the foregoing, or any
other covenant herein contained, in connection with the receipt of any necessary
approvals under the HSR Act, neither the Company nor any Company Subsidiary
shall be entitled to divest or hold separate or otherwise take or commit to take
any action that limits Parent's or Sub's freedom of action with respect to, or
their ability to retain, the Company or any Company Subsidiary or any material
portions thereof or any of the businesses, product lines, properties or assets
of the Company or any Company Subsidiary, without Parent's prior written
consent.

                           (b) Prior to the Closing, subject to Applicable Law,
each party shall promptly consult with the other parties hereto with respect to,
provide any necessary information with respect to, and provide the other parties
(or their respective counsel) with copies of, all filings made by such party
with any Governmental Entity or any other information supplied by such party to
a Governmental Entity in connection with this Agreement, the Merger and the
other Transactions. Each party hereto shall promptly inform the other parties of
any communication from any Governmental Entity regarding any of the
Transactions. If any party hereto or Affiliate thereof receives a request for
additional information or documentary material from any such Governmental Entity
with respect to any of the Transactions, then such party shall endeavor in good
faith to make, or cause to be made, as soon as reasonably practicable and after
consultation with the other parties, an appropriate response in compliance with
such request. To the extent that transfers, amendments or modifications of
Permits (including Environmental Permits) are required as a result of the
execution of this Agreement or consummation of any of the Transactions, the
Company shall use its reasonable best efforts to effect such transfers,
amendments or modifications.

                           (c) The Company and Parent shall file, as soon as
practicable, notifications under the HSR Act and respond as promptly as
practicable to any inquiries received from the Federal Trade Commission and the
Antitrust Division of the Department of Justice for additional information or
documentation and respond as promptly as practicable to all inquiries and
requests received from any State Attorney General or other Governmental Entity
in connection with antitrust matters. Concurrently with the filing of
notifications under the HSR Act or as soon thereafter as practicable, the
Company and Parent shall each request early termination of the HSR Act waiting
period.

                           (d) Notwithstanding the foregoing, except as provided
in Section 7.1(b)(ii), nothing contained in this Agreement shall be deemed to
require the Company, Parent or Sub to commence any litigation against any entity
in order to facilitate the consummation of any of the Transactions or to defend
against any litigation brought by any Governmental Entity seeking to prevent the
consummation of any of the Transactions.

                  5.4 Access to Information. To the extent permitted by
applicable law, upon reasonable notice, the Company shall (and shall cause each
Company Subsidiary to), afford to the officers, employees, accountants, counsel,
financing sources and other representatives of Parent, access, during normal
business hours during the period prior to the Effective Time, to all

                                       34
<PAGE>   40
its properties, books, contracts, commitments and records and, during such
period, the Company shall (and shall cause each Company Subsidiary to), furnish
promptly to Parent (a) a copy of each report, schedule, registration statement
and other document filed or received by it during such period pursuant to the
requirements of the federal securities laws and (b) all other information
concerning its business, properties and personnel as Parent may reasonably
request. Access shall include the right to conduct such management information
systems, risk management and environmental studies as Parent, in its discretion,
shall reasonably deem appropriate. After the time the persons designated by
Parent have been elected to, and shall constitute a majority of, the Company
Board pursuant to Section 1.3 hereof (the "Appointment Date"), the Company shall
provide Parent and such persons as Parent shall designate with such information,
at any time as Parent shall request. Until the Effective Time, unless otherwise
required by law or in order to comply with disclosure requirements applicable to
the Offer Documents or the Proxy Statement, Parent will hold any such
information which is nonpublic in confidence in accordance with the
Confidentiality Agreements, dated as of May 24, 1999 and May 26, 1999 (the
"Confidentiality Agreements"), entered into by and among the members of Parent
and the Company.

                  5.5 Publicity. The initial press release with respect to the
execution of this Agreement shall be a joint press release acceptable to Parent
and the Company. Thereafter, until the Appointment Date or the date the
Transactions are terminated or abandoned, neither the Company, Parent nor any of
their respective Affiliates shall issue or cause the publication of any press
release or other announcement with respect to the Merger, this Agreement or the
other Transactions without prior consultation with the other parties, except to
the extent required by law, the rules and regulations of any national securities
exchange or over-the-counter market or by any listing agreement with a national
securities exchange or over-the-counter market.

                  5.6 State Takeover Laws. Notwithstanding any other provision
in this Agreement, in no event shall the approval given by the Company Board
with respect to Section 203 of the DGCL be withdrawn, revoked or modified by the
Company Board. If any state takeover statute other than Section 203 of the DGCL
becomes or is deemed to become applicable to the Company, the Stockholder
Agreement, the Offer, the Share Purchase, the acquisition of Shares pursuant to
the Offer or the Merger, the Company shall take all action necessary to render
such statute inapplicable to all of the foregoing.

                  5.7 Directors' and Officers' Insurance and Indemnification.

                           (a) The Company shall, to the fullest extent
permitted under the applicable provisions of the DGCL, the terms of the
Company's Certificate of Incorporation or By-Laws and regardless of whether the
Merger becomes effective, indemnify and hold harmless, and, after the Effective
Time, the Surviving Corporation shall, to the fullest extent permitted under the
applicable provisions of the DGCL, indemnify and hold harmless, each present and
former director, officer or employee of the Company or any Company Subsidiary
(collectively, the "Company Indemnified Parties") against any costs or expenses
(including reasonable attorneys' fees), judgments, losses, claims, damages and
liabilities incurred in connection with, and amounts paid in settlement of, any
claim, action, suit, proceeding or investigation, whether civil, criminal,
administrative or investigative and wherever asserted, brought or filed, based
on the fact that such person is or was a director, officer or employee of the
Company or any

                                       35
<PAGE>   41
Company Subsidiary and (x) arising out of or pertaining to the Transactions or
(y) otherwise with respect to any acts or omissions or alleged acts or omissions
occurring at or prior to the Effective Time, in each case for a period of six
years after the Effective Time. In the event of any such claim, action, suit,
proceeding or investigation (whether arising before or after the Effective
Time), (i) any counsel retained by the Company Indemnified Parties for any
period after the Effective Time must be reasonably satisfactory to the Surviving
Corporation, (ii) after the Effective Time, the Surviving Corporation shall pay
the reasonable fees and expenses of such counsel, promptly after statements
therefor are received, and (iii) the Surviving Corporation will cooperate in the
defense of any such matter; provided, however, that the Surviving Corporation
shall not be liable for any settlement effected without its written consent
(which consent shall not be unreasonably withheld or delayed); and provided,
further, that, in the event that any claim or claims for indemnification are
asserted or made within such six-year period, all rights to indemnification in
respect of any such claim or claims shall continue until the disposition of any
and all such claims. The Company Indemnified Parties as a group shall be
reimbursed for the costs of only one law firm to represent them with respect to
any single action unless there is, under applicable standards of professional
conduct, a conflict on any significant issue between the positions of any two or
more Company Indemnified Parties. The indemnity agreements of the Surviving
Corporation in this Section 5.7 (a) shall extend, on the same terms to, and
shall inure to the benefit of and shall be enforceable by, each person or entity
who controls, or in the past controlled, any present or former director, officer
or employee of the Company or any Company Subsidiary.

                           (b) At the Closing, the Surviving Corporation shall
purchase directors' and officers' liability tail insurance covering those
persons who are currently covered by the Company's directors' and officers'
liability insurance policy (a copy of which has been made available to Parent)
for a period of six years on terms (including the amounts of coverage and the
amounts of deductibles, if any) that are no less favorable to the covered
persons than the terms now applicable to them under the Company's current
policy; provided, however, that in no event shall the Surviving Corporation be
required to expend more than $125,000; and provided, further, that, if the
premium for such coverage exceeds such amount, the Surviving Corporation shall
purchase a policy with the greatest coverage available for such amount,

                           (c) This Section 5.7 shall survive the consummation
of the Merger at the Effective Time, and shall be binding on all successors and
assigns of the Surviving Corporation (including any transferee of all or
substantially all the assets of Parent or the Surviving Corporation).

                  5.8 Conduct of Business of Sub. During the period of time from
the date of this Agreement to the Effective Time, Sub shall not engage in any
activities of any nature except as provided in or contemplated by this
Agreement.

                  5.9 Transfer of Stockholder's Shares. The Company hereby
waives any rights the Company may have under any agreement or otherwise to
object to the transfer to Sub or Parent of any or all Shares held by Stockholder
and hereby covenants not to consent to the transfer of any Shares held by
Stockholder to any other person unless (i) the Company will have obtained the
specific, prior written consent of Parent with respect to any such transfer or
(ii) this Agreement will have been terminated pursuant to Article VII hereof.

                                       36
<PAGE>   42
                  5.10 Notification of Certain Matters. The Company shall give
prompt notice to Parent of (i) the occurrence or non-occurrence of any event the
occurrence or non-occurrence of which would cause any representation or warranty
contained in this Agreement to be untrue or inaccurate in any material respect
at or prior to the Effective Time and (ii) any material failure of the Company
to comply with or satisfy any covenant, condition or agreement to be complied
with or satisfied by it hereunder, provided, however, that the delivery of any
notice pursuant to this Section 5.10 shall not limit or otherwise affect the
remedies available hereunder to the party receiving such notice.

                  5.11 Company Employees. The Surviving Corporation will (i)
continue to provide each person (other than Worksite Employees) employed by the
Company or any Company Subsidiary on the Closing Date and who continue to be
employed by the Company or any Company Subsidiary thereafter such benefits and
salary comparable in the aggregate to the benefits and salary previously paid or
provided by the Company or any Company Subsidiary, as applicable (other than
stock options or stock awards), as of the Closing Date for a period ending on
the first anniversary of the Effective Time and (ii) grant to each such person
credit for his/her years of service with the Company or any Company Subsidiary,
as applicable, for purposes of calculating such person's right to participate in
applicable benefit plans and programs and the level of such participation.

                  5.12 Guaranty. The Company shall as promptly as practicable
after the date hereof, and in any event prior to the purchase of any Shares
pursuant to the Offer, obtain (i) a guaranty from Ultimate Parent in form and
substance reasonably satisfactory to Parent, pursuant to which Ultimate Parent
shall guaranty to Parent the earnings before interest, taxes, depreciation and
amortization (EBITDA) projected to be received by the Company under the
Subscriber Services Agreement, dated as of July 1, 1999, by and between Ultimate
Parent and the Company, relating to Ultimate Parent's PROH Division (the "PROH
Contract"), which such EBITDA amounts are set forth in Schedule 5.12 and (ii) an
irrevocable letter of credit or surety bond from a reputable and financially
sound financial institution or insurance company, or such other security, in
each case in form and substance reasonably satisfactory to Parent securing the
EBITDA payable with respect to the guaranty described in clause (i) or with
respect to the PROH Contract, as the case may be, and the EBITDA set forth in
Schedule 5.12 projected to be received by the Company under the Subscriber
Services Agreement dated as of July 1, 1999 by and between Ultimate Parent and
the Company relating to Ultimate Parent's Support Services Division.

contemplated herein or in the Irrevocable Proxy not be consummated or otherwise
materially limiting or restricting ownership or the operation of the business of
the Surviving Corporation, or (ii) pending by any Governmental Entity any suit,

         right to terminate this Agreement under this Section 7.1(b)(i) shall
         not be available to any party whose failure to fulfill any obligation

         Common Stock pursuant to the Offer on or prior to such date;

                                    (ii) if any Governmental Entity shall have

however, that if this Agreement is terminated by the Company pursuant to Section

provisions of the DGCL, at any time prior to the Effective Time, the parties
hereto may modify or amend this Agreement, by written agreement executed and
delivered by duly authorized officers of the respective parties; provided,
however, that after approval of this Agreement by the stockholders of the

payable in the Merger or adversely affects the rights of the Company's
stockholders hereunder without the approval of such stockholders.

Agreement, any failure of any of the parties to comply with any obligation,
covenant, agreement or condition herein may be waived by the party or parties
entitled to the benefits thereof only by a written instrument signed by the
party granting such waiver, but such waiver or failure to insist upon strict
compliance with such obligation, covenant, agreement or condition shall not
operate as a waiver of, or estoppel with respect to, any subsequent or other
failure.

or to such other persons or addresses as may be designated in writing by the
party to receive such notice.

                  8.8 Entire Agreement, Assignment. This Agreement and the
Confidentiality Agreements(a) constitute the entire agreement among the parties
with respect to the subject matter hereof and supersede all other prior
agreements and understandings, both written and oral, among the parties or any
of them with respect to the subject matter hereof and (b) shall not be assigned
by operation of law or otherwise without the prior written consent of the other
parties; except that Parent and Sub may assign, in its sole discretion, any or
all of its rights, interests and obligations hereunder to Parent or to any
direct or indirect wholly owned subsidiary of Parent or to any other entity
owned by the same members of Parent. Subject to the preceding sentence, this
Agreement will be binding upon, inure to the benefit of and be enforceable by
the parties and their respective permitted successors and assigns.

                  8.9 Parties in Interest. Nothing in this Agreement, express or
implied, other than the right to receive the consideration payable in the Merger
pursuant to Article II hereof and as provided in Section 5.7 hereof, is intended
to or shall confer upon any other person any rights, benefits or remedies of any
nature whatsoever under or by reason of this Agreement.

                  8.10 Obligation of Parent. Whenever this Agreement requires
Sub to take any action, such requirement shall be deemed to include an
undertaking on the part of Parent to cause Sub to take such action and a
guarantee of the performance thereof.

                  8.11 Validity. If any term, provision, covenant or restriction
of this Agreement is held by a court of competent jurisdiction or other
authority to be invalid, void, unenforceable

                                       43
<PAGE>   49
or against its regulatory policy, the remainder of the terms, provisions,
covenants and restrictions of this Agreement shall remain in full force and
effect and shall in no way be affected, impaired or invalidated so long as the
economic or legal substance of the transactions contemplated hereby is not
affected in any manner materially adverse to any party.

                  8.12 Captions. The Article, Section and paragraph captions
herein are for convenience of reference only, do not constitute part of this
Agreement and shall not be deemed to limit or otherwise affect any of the
provisions hereof.

                  8.13 Specific Performance. Each of the parties hereto
acknowledges and agrees that in the event of any breach of this Agreement, each
non-breaching party would be irreparably and immediately harmed and could not be
made whole by monetary damages. It is accordingly agreed that the parties hereto
(a) will waive, in any action for specific performance, the defense of adequacy
of a remedy at law and (b) shall be entitled, in addition to any other remedy to
which they may be entitled at law or in equity, to compel specific performance
of this Agreement in any action instituted in a court of competent jurisdiction.

                  8.14 "Knowledge" of the Company. For purposes of this
Agreement, unless otherwise expressly provided where the term is used,
"knowledge" of the Company will be deemed to mean (i) the actual knowledge of
any director or executive officer of the Company or any Company Subsidiary and
(ii) the knowledge that any such director or executive officer would have had if
he or she, in connection with the confirmation of the accuracy of the
representations and warranties of the Company in this Agreement, had made due
inquiry of the officers, employees, advisors, and agents of the Company or any
Company Subsidiary who are primarily responsible for the subject matter of such
representations and warranties.

                  8.15 Confidentiality. During the period from the date of this
Agreement to the Effective Date, the Company shall, and shall cause each Company
Subsidiary to, maintain the confidentiality of all confidential information
given to them by Parent or Sub or any Affiliate of Parent or Sub, in connection
with this Agreement, in the same manner that the recipient of the information
maintains the confidentiality of its own confidential information. If this
Agreement is terminated in accordance with Article VII, the Company shall, and
shall cause each Company Subsidiary to, promptly return all such confidential
information and materials, and the provisions of the foregoing sentence shall
survive such termination indefinitely. The Company acknowledges that any breach
of this Section 8.15 may cause irreparable injury to Parent or Sub for which
money damages could not adequately compensate. If there is such a breach, the
aggrieved parties shall be entitled, in addition to all other rights or remedies
it may have at law or in equity, to have an injunction issued by any competent
court enjoining and restraining the breaching parties from continuing such
breach. The existence of any claim or cause of action which any of the breaching
parties may have against the aggrieved parties shall not constitute a defense or
bar to the enforcement of this Section 8.15.

Nova Care Employee Services, Inc., a Delaware corporation (the "Company").
Capitalized terms used and not defined in this Agreement shall have the meaning

                  WHEREAS, concurrently with the execution of this Agreement,
Parent, Sub and the Company are entering into the Merger Agreement, providing
for the making of a tender offer (the "Offer") to purchase all of the issued and
outstanding shares of the Company's common stock, par value $0.01 per share (the
"Shares"), at a price per Share equal to the Offer Price and, following the
completion of the Offer, the merger (the "Merger") of Sub and the Company,
whereby each Share not purchased pursuant to the Offer (other than Shares owned
by Parent, Sub or any other wholly owned subsidiary of Parent, Shares held in
the treasury of the Company and Dissenting Shares) will be converted into the
right to receive in cash the Offer Price in accordance with the terms of the
Merger Agreement; and

                  WHEREAS, the Company desires to induce Parent and Sub to enter
into the Merger Agreement and to facilitate the prompt completion of the Merger
following the purchase of Shares pursuant to the Offer.

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

                  1. Grant of Option. The Company hereby grants to Sub an
irrevocable option (the "Option") to purchase up to that number of newly issued
Shares (the "Option Shares") equal to the number of Shares, that when added to
the number of Shares owned by Sub and its affiliates immediately following
consummation of the Offer, shall constitute 90% of the Shares then outstanding
on a fully diluted basis (giving effect to the issuance of the Option Shares)
for a consideration per Option Share equal to the Offer Price; provided,
however, that the number of Option Shares shall not exceed that number equal to
19.9% of the Shares outstanding on the date of this Agreement.

                  2. Exercise of the Option. The Option may be exercised by Sub
at any time after the acceptance for payment by Sub of Shares pursuant to the
Offer in accordance with the terms of the Merger Agreement. In the event Sub
wishes to exercise the Option, Sub shall give written notice (the "Notice") of
its exercise of the Option and specifying the number of Shares owned by Sub and
its affiliates immediately following consummation of the Offer and a place and a
time (which shall not be less than three business days from the date of the
Notice) for the closing of such purchase. The Company shall, within two business
days after receipt of the Notice, deliver written notice to Sub specifying the
number of Option Shares.

                  3. Payment and Delivery of Certificates. At the closing
hereunder: (i) the Company will deliver to Sub a certificate or certificates
representing the number of Option

Shares so purchased and (ii) Sub will make payment to the Company of the
aggregate price for the Option Shares being purchased, as stated in the Notice,
by check or wire transfer in an amount equal to the product of (x) the Offer
Price and (y) the total number of Option Shares delivered at the closing. The
Company shall pay all expenses, and any and all United States Federal, state and
local taxes and other charges, that may be payable in connection with the
preparation, issuance and delivery of stock certificates under this Section 3.

                  4. Representations and Warranties of the Company. The Company
hereby represents and warrants to Parent and Sub as follows:

                           4.1. The Company has all requisite corporate power
and authority to enter into and perform all of its obligations under this
Agreement. The execution and delivery of this Agreement and the consummation by
the Company of the transactions contemplated hereby have been duly authorized by
all necessary corporate action on the part of the Company. This Agreement has
been duly executed and delivered by the Company.

                           4.2. The Company has taken all necessary corporate
action to authorize and reserve for issuance, and at all times prior to the
termination of this Agreement shall have reserved, all of the Option Shares
issuable pursuant to this Agreement.

                           4.3. The Shares to be issued upon exercise of the
Option, upon their issuance and delivery in accordance with this Agreement as
provided herein, will be duly authorized, validly issued, fully paid and
non-assessable, will be delivered free and clear of all security interests,
liens, claims, pledges, options, rights of first refusal, agreements,
limitations on Sub's voting rights, charges, adverse rights and other
encumbrances of any nature whatsoever (other than this Agreement) and will not
be subject to any preemptive rights. Upon the delivery to Sub by the Company of
a certificate or certificates evidencing the Option Shares, Sub will receive
good, valid and marketable title to the Option Shares.

                  5. Representations and Warranties of Parent and Sub. Each of
Parent and Sub hereby represents and warrants to the Company that (i) it has all
requisite power and authority to enter into and perform all of its obligations
under this Agreement; (ii) the execution and delivery of this Agreement and the
consummation of the transactions contemplated hereby have been duly authorized
by all necessary action on the part of Parent and Sub; (iii) this Agreement has
been duly executed and delivered by Parent and Sub and, assuming the due and

and binding obligation of Parent and Sub, enforceable against each of Parent and
Sub in accordance with its terms, except as such enforceability may be limited
by applicable bankruptcy, insolvency, reorganization, moratorium or other
similar laws affecting creditors' rights generally, and by general equitable
principles; and (iv) if and when Sub exercises the Option, it will be acquiring
the Option Shares pursuant to this Agreement for its own account and not with a
view to any public distribution thereof.

                  6. Adjustment Upon Changes in Capitalization. In the event of
any change in the number of issued and outstanding Shares by reason of any stock
dividend, subdivision, merger, recapitalization, combination, conversion or
exchange of shares, or any other change in the corporate or capital structure of
the Company (including, without limitation, the declaration
<PAGE>   4
                                                                               4

or payment of any extraordinary dividend of cash or securities) which would have
the effect of diluting or otherwise adversely affecting Sub's rights and
privileges under this Agreement, the number and kind of the Option Shares and
the consideration payable in respect of the Option Shares shall be appropriately
and equitably adjusted to restore to Sub its rights and privileges under this
Agreement.

                  7. Termination. This Agreement will terminate upon the earlier

hereto (whether by operation of law or otherwise) without the prior written
consent of the other parties, except that Sub may assign, in its sole
discretion, any or all of its rights, interests and obligations hereunder to
Parent or to any direct or indirect wholly owned Subsidiary of Parent or to any
other entity owned by, or controlling, controlled by or under common control
with the same equityholders of Parent. Subject to the preceding sentence, this
Agreement will be binding upon, inure to the benefit of and be enforceable by
the parties and their respective successors and permitted assigns.

                  9. Notices. All notices and other communications hereunder
shall be in writing and shall be deemed to have been duly given (and shall be
deemed to have been duly received if so given) if personally delivered or sent
by registered or certified mail, postage prepaid, or telecopy addressed to the
respective parties at their addresses specified in Section 8.7 of the Merger
Agreement.

                  10. Specific Performance. Each of the parties hereto
acknowledges and agrees that in the event of any breach by the Company of this
Agreement, Parent and Sub would be irreparably and immediately harmed and could
not be made whole by monetary damages. It is accordingly agreed that the Company
will waive, in any action for specific performance, the defense of adequacy of a
remedy at law, and Parent and Sub shall be entitled, in addition to any other
remedy to which they may be entitled at law or in equity, to compel specific
performance of this Agreement in any action instituted in a court of competent
jurisdiction.

                  11. Governing Law. This Agreement shall be governed by and

waive compliance with the performance of any obligation or other act of any
other party hereto or (ii) waive any inaccuracy in the representations and
warranties contained herein or in any document delivered pursuant hereto. Any
such extension or waiver shall be valid only if set forth in an instrument in
writing signed by the party or parties to be bound thereby. 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.

policy, the remainder of the terms, provisions, covenants and restrictions of
this Agreement shall remain in full force and effect and shall in no way be

NOVACARE EMPLOYEE SERVICES ANNOUNCES SALE OF COMPANY

September 9, 1999 10:32 AM
NORRISTOWN, Pa., Sept. 9/PRNewswire/-- NovaCare Employee Services, Inc. NCES,
a premier national employee services company, or professional employer
organization (PEO), announced today a definitive agreement to sell the company
to an investment group comprising Patricof & Co. Ventures, Inc., Fidelity
Ventures Limited and AFLAC Incorporated (the Investors). Under the terms of the
agreement, a new private company established by the Investors will acquire all
the stock of NovaCare Employee Services at a price of $2.50 per share of common
stock.

The purchase will be effected through a cash tender offer to NovaCare Employee
Services stockholders and subsequent merger of NovaCare Employee Services into a
new private company managed by the Investors. The tender offer will commence on
or about September 15, 1999. NovaCare Employee Services has 30,273,782 fully
diluted shares of common stock outstanding.

"After several months of careful review of our strategic alternatives, we are
pleased with this transaction, which partners NovaCare Employee Services with
three firms with extensive understanding of the PEO industry and the resources
and synergies to support our future growth," said Loren J. Hulber, president and
chief executive officer.

Following the merger, Loren J. Hulber will be elected Chairman of the Board and
Craig P. Coy will be elected Chief Executive Officer. Mr. Coy has been Chief
Executive Officer of HR Logic, Inc., a portfolio company jointly owned by
Patricof & Co. Ventures, Inc. and Fidelity Ventures Limited, headquartered in
Newton, Massachusetts. Operations of NovaCare Employee Services will remain
intact and the company will, over a six month period, change its name to
NovaSource, Inc.

NovaCare, Inc., NOV holder of approximately 64% of NovaCare Employee Services'
outstanding common stock, also executed a definitive agreement, subject to
certain conditions, to tender its shares in the tender offer at the price of
$2.50 per share.

The tender offer is subject to the approval of the NovaCare, Inc. stockholders
and the satisfaction of customary closing conditions. The tender offer is
expected to close during October 1999. NovaCare Employee Services' previously
announced agreement to acquire Unified Management Corporation has terminated and
that transaction will not occur.

NovaCare Employee Services engaged CIBC World Markets to render a fairness
opinion on this transaction.

NovaCare Employee Services, Inc. is a premier national professional employer
organization. The company is an employee services company that provides small-
to medium-sized businesses with comprehensive, fully integrated outsourcing
solutions to human resource needs, including payroll management, risk
management, benefits procurement and management, unemployment insurance services

Except for historical information, matters discussed above including, but not
limited to, statements concerning future growth, are forward-looking statements
that are based on management's estimates, assumptions and projections. Important
factors that could cause results to differ materially from those expected by
management include management retention and development, management's success in
integrating acquired businesses, in developing and introducing new products and
lines of business and in entering new geographic markets, maintaining material
customer contracts, material changes in the economics of the contracts with
NovaCare, Inc., the ability of the company, its customers and its suppliers to
complete assessment, testing and remediation of Year 2000 issues, adverse
Internal Revenue Service rulings and state regulations with respect to the
employer status of employee services businesses and the company's ability to
implement the employee services business model.
