                                    ARTICLE 2

                                   THE MERGER

         ARTICLE 2.1. THE MERGER.

         (a) At the Effective Time, the Company shall be merged with and into
Acquiror (the "MERGER") in accordance with the terms and conditions of this
Agreement and the Delaware General Corporation Law (the "DGCL"), at which time
the separate corporate existence of the Company shall cease and Acquiror shall
continue in existence. In its capacity as the corporation surviving the Merger,
this Agreement sometimes refers to Acquiror as the "SURVIVING CORPORATION".

         (b) As soon as practicable on or after the Closing Date, Acquiror will
file a certificate of merger or other appropriate documents (the "CERTIFICATE OF
MERGER") with the Delaware Secretary of State (the "SECRETARY OF STATE") and
make all other filings or recordings required by the DGCL in connection with the
Merger. The Merger shall become effective at the time when the Certificate of
Merger is duly filed with and accepted by the Secretary of State, or at such
later time as is agreed upon by the parties and specified in the Certificate of
Merger (such time as the Merger becomes effective is referred to herein as the
"EFFECTIVE TIME").

         (c) From and after the Effective Time, the Merger shall have the
effects set forth in Section 259 of the DGCL.

         (d) The closing of the Merger (the "CLOSING") shall be held at the
offices of Dewey Ballantine LLP, 1301 Avenue of the Americas, New York, NY 10019
(or such other place as agreed by the parties) on the later of one Business Day
after (a) the date of the Company Stockholder Meeting, (b) the date of the
Acquiror Stockholder Meeting, or (c) the day on which all of the conditions set
forth in Article 9 are satisfied or waived, unless the parties hereto agree to
another date. The date upon which the Closing occurs is hereinafter referred to
as the "CLOSING DATE".

         ARTICLE 2.2. ORGANIZATIONAL DOCUMENTS. The Certificate of Merger shall
provide that at the Effective Time (i) Acquiror's certificate of incorporation
in effect immediately prior to the Effective Time shall be the Surviving
Corporation's certificate of incorporation and (ii) Acquiror's bylaws in effect
immediately prior to the Effective Time shall be the Surviving Corporation's
bylaws, in each case until amended in accordance with applicable law.

         ARTICLE 2.3. DIRECTORS AND OFFICERS.

         (a) From and after the Effective Time (until successors are duly
elected or appointed and qualified), (i) Acquiror's directors at the Effective
Time shall be the Surviving Corporation's directors and (ii) the officers of
Acquiror immediately prior to the Effective Time shall be the Surviving
Corporation's officers.

         (b) Acquiror agrees to take all necessary actions to slate and to use
its best efforts to obtain the approval of, the election of Russell Carson and
James Dalton (or, if unavailable, another member of the Company's current Board
of Directors reasonably acceptable to Acquiror)


                                       6
<PAGE>   12

to serve, from and after the Effective Time, on Acquiror's Board of Directors.

                                    ARTICLE 3

                  CONVERSION OF SECURITIES AND RELATED MATTERS

         ARTICLE 3.1. CANCELLATION OF TREASURY STOCK AND ACQUIROR OWNED SHARES.
As of the Effective Time, by virtue of the Merger and without any action on the
part of the holder of any Company Shares, each Company Share held by the Company
as treasury stock or owned by Acquiror, any Acquiror Subsidiary or any Company
Subsidiary immediately prior to the Effective Time shall be canceled and
retired, and no payment shall be made or consideration delivered in respect
thereof.

         ARTICLE 3.2. CONVERSION OF COMPANY SHARES.

         (a) As of the Effective Time, by virtue of the Merger and without any
action on the part of the holder of any Company Shares, except as otherwise
provided in this Section 3.2, each Company Share issued and outstanding
immediately prior to the Effective Time (other than shares to be cancelled in
accordance with Section 3.1) shall be converted into the right to receive .4107
Acquiror Shares (the "STOCK CONSIDERATION") and the right to receive in cash
from Acquiror, without interest, an amount equal to $3.50 (the $3.50 and the
increase, if any, contemplated by Section 3.2(b) is hereinafter referred to as
the "CASH CONSIDERATION" and, together with the Stock Consideration, the "MERGER
CONSIDERATION").

         (b) In the event that the 20 trading day average closing price of an
Acquiror Share (as reported on NASDAQ) for the period ending five Business Days
prior to the date of the Company Stockholder Meeting (the "MEETING PRICE") is
less than $21.00, the Company shall have the right, in its sole discretion, and
no later than four Business Days prior to the Company Stockholder Meeting, to
give notice to Acquiror of the Company's intention to terminate this Agreement
(a "PRICE DEFICIENCY NOTICE"); provided, however, that if the Company gives a
Price Deficiency Notice, Acquiror shall have the right, in its sole discretion
and by the giving of notice to the Company no later than two (2) Business Days
after the Company gives the Price Deficiency Notice, to increase the Cash
Consideration, by an amount equal to the difference between the Meeting Price
and $21.00, multiplied by .4107, rounded up to the nearest whole cent. If
Acquiror does not exercise its right to increase the Cash Consideration, the
Company shall have the right to terminate this Agreement as provided in Section
10.1(c)(i).

         (c) Fractional Shares. No fractional shares shall be issued in the
Merger. All fractional shares that a holder of any Company Shares or Company
Stock Options would otherwise be entitled to receive as a result of the Merger
shall be aggregated. If a fractional Acquiror Share results from the
aggregation, the holder shall be entitled to receive, in lieu thereof, a cash
amount, without interest, determined by multiplying the fraction of an Acquiror
Share to which the holder would otherwise have been entitled by the Meeting
Price rounded up to the nearest whole cent. As promptly as practicable after the
determination of the amount of cash, if any, to be paid to holders of fractional
share interests, the Exchange Agent shall so notify Acquiror, and Acquiror shall
deposit that amount with the Exchange Agent and shall cause the Exchange Agent


                                       7
<PAGE>   13

to forward payments to the holders of fractional share interests, subject to and
in accordance with the terms of this Section 3.2.

         ARTICLE 3.3. CAPITALIZATION CHANGES. If at any time during the period
between the date of this Agreement and the Effective Time, any change in the
outstanding shares of capital stock of Acquiror or securities convertible or
exchangeable into capital stock of Acquiror shall occur, including by reason of
any reclassification, recapitalization, stock split or combination, exchange or
readjustment of shares, or any dividend or distribution thereon (other than
regular quarterly cash dividends) or a record date with respect to any of the
foregoing shall occur during such period, the number of Acquiror Shares
constituting part of the Merger Consideration shall be appropriately adjusted to
provide to the holders of the Acquiror Shares and the Company Shares the same
economic effect as contemplated by this Agreement prior to the consummation of
such event.

         ARTICLE 3.4. EXCHANGE OF CERTIFICATES.

         (a) Exchange Agent. Promptly after the date hereof, Acquiror shall
appoint a bank or trust company reasonably acceptable to the Company as an agent
(the "EXCHANGE AGENT") for the benefit of holders of Company Shares for the
purpose of exchanging, pursuant to this Article 3, certificates representing the
Company Shares (the "CERTIFICATES"). Acquiror will make available to the
Exchange Agent, as needed, the Merger Consideration, together with any dividends
or distributions with respect thereto, if any, to be paid in respect of Company
Shares pursuant to this Article 3 (the "EXCHANGE FUND"), and, except as
contemplated by Section 3.4(e) or Section 3.4(g) hereof, the Exchange Fund shall
not be used for any other purpose.

         (B) Exchange Procedures. As promptly as practicable after the Effective
Time, Acquiror shall send, or shall cause the Exchange Agent to send, to each
record holder of Certificates a letter of transmittal and instructions (which
shall be in customary form and specify that delivery shall be effected, and risk
of loss and title shall pass, only upon delivery of the Certificates to the
Exchange Agent), for use in the exchange contemplated by this Section 3.4. Upon
surrender of a Certificate to the Exchange Agent, together with a duly executed
letter of transmittal, the holder shall be entitled to receive in exchange
therefor the Merger Consideration and any unpaid dividends and distributions
thereon as provided in this Article 3 in respect of the Company Shares
represented by the Certificate (after giving effect to any required withholding
tax). Until surrendered as contemplated by this Section 3.4, each Certificate
shall be deemed after the Effective Time to represent only the right to receive
the Merger Consideration and any unpaid dividends and distributions thereon as
provided in this Article 3. If any portion of the Merger Consideration is to be
paid to a Person other than the registered holder of the Certificate, it shall
be a condition to payment that the Certificate so surrendered shall be properly
endorsed or otherwise be in proper form for transfer and that the Person
requesting payment shall pay to the Exchange Agent any transfer or other taxes
required as a result of payment to a Person other than the registered holder of
the Certificate or establish to the satisfaction of the Exchange Agent that the
tax has been paid or is not payable.

         (c) Distributions with Respect to Unexchanged Shares. Whenever a
dividend or other distribution is declared by Acquiror in respect of the
Acquiror Shares, the record date for which is at or after the Effective Time,
that declaration shall include dividends or other distributions in respect of
all Acquiror Shares issuable pursuant to this Agreement. No dividends or other


                                       8
<PAGE>   14

distributions declared or made after the Effective Time with respect to Acquiror
Shares constituting part of the Merger Consideration shall be paid to the holder
of any unsurrendered Certificate, and no cash payment in lieu of fractional
shares shall be paid to any holder, until the Certificate is surrendered as
provided in this Section 3.4. Following surrender, there shall be paid, without
interest, to the Person in whose name the Acquiror Shares have been registered
(i) at the time of surrender, the amount of dividends or other distributions
with a record date after the Effective Time previously paid or payable on the
date of surrender with respect to whole Acquiror Shares, less the amount of any
withholding taxes that may be required thereon, and (ii) at the appropriate
payment date subsequent to surrender, the amount of dividends or other
distributions with a record date after the Effective Time but prior to surrender
and a payment date subsequent to surrender payable with respect to whole
Acquiror Shares, less the amount of any withholding taxes which may be required
thereon.

         (d) No Further Rights in Company Shares. All Acquiror Shares issued or
cash paid upon surrender of Certificates in accordance with the terms hereof
shall be deemed to have been issued in full satisfaction of all rights
pertaining to Company Shares represented thereby. From and after the Effective
Time, the holders of Certificates shall cease to have any rights with respect to
Company Shares, except as otherwise provided herein or by law. As of the
Effective Time, the stock transfer books of the Company shall be closed and
there shall be no further registration of transfers on the Company's stock
transfer books of any Company Shares. If, after the Effective Time, Certificates
are presented to the Surviving Corporation for any reason, they shall be
canceled and exchanged as provided in this Section 3.4.

         (e) Return of Merger Consideration. Upon demand by Acquiror, the
Exchange Agent shall deliver to Acquiror any portion of the Merger Consideration
made available to the Exchange Agent pursuant to this Section 3.4 that remains
undistributed to holders of Company Shares six months after the Effective Time.
Holders of Certificates who have not complied with this Section 3.4 prior to the
demand by the Acquiror shall thereafter look only to Acquiror for payment of any
claim to the Merger Consideration and dividends or distributions, if any, in
respect thereof.

         (f) No Liability. Neither Acquiror nor the Exchange Agent shall be
liable to any Person in respect of any Company Shares (or dividends or
distributions with respect thereto) for any amounts paid to a public official
pursuant to any applicable abandoned property, escheat or similar law.

         (g) Withholding Rights. Acquiror shall be entitled to deduct and
withhold from the Merger Consideration (and any dividends or distributions
thereon) otherwise payable hereunder to any Person, and to deduct and withhold
from any cash or Acquiror Shares paid to any holder of a Company Option, any
amounts which it is required to deduct and withhold with respect to payment
under any provision of federal, state or local income, employment or other tax
law. To the extent that Acquiror withholds those amounts, the withheld amounts
shall be treated for all purposes of this Agreement as having been paid to the
holder of Company Shares in respect of which deduction and withholding was made
by Acquiror.

         (h) Lost Certificates. If any Certificate has been or is claimed to
have been lost, stolen or destroyed, upon the making of an affidavit of that
fact by the person claiming that Certificate has


                                       9
<PAGE>   15

been lost, stolen or destroyed and, if required by Acquiror, the posting by such
Person of a bond, in such reasonable amount as Acquiror may direct, as indemnity
against any claim that may be made against it with respect to that Certificate,
the Exchange Agent will deliver in exchange for such lost, stolen or destroyed
Certificate, the proper amount of the Merger Consideration, together with any
unpaid dividends and distributions on any Acquiror Shares, as contemplated by
this Article 3.

         ARTICLE 3.5. COMPANY STOCK OPTIONS.

         (a) At the Effective Time, each option to purchase Company Shares
(each, a "COMPANY OPTION") outstanding under any stock option or compensation
plan or arrangement of the Company, whether or not vested or exercisable, shall
be converted, at the holder's election (made prior to the Effective Time) to
either (i) the right to receive, as soon as practicable following the Effective
Time, cash and a number of Acquiror Shares determined as follows:

x        Cash Consideration

  cash =   _______________________                                      x Spread
           Total Option Consideration

  number of                 =        .4107 x the Meeting Price     x Spread
                                     -------------------------
  Acquiror Shares                    Total Option Consideration

                                     --------------------------------
                                              Meeting Price

or (ii) a fully vested and exercisable option to purchase, on the same terms and
conditions as were applicable to such Company Option as of the Effective Time
(A) a number of Acquiror Shares determined by dividing the Total Option
Consideration by the Meeting Price and multiplying the result by the number of
Company Shares subject to the Company Option (rounded to the nearest whole
Acquiror share), (B) at a price per share equal to the aggregate exercise price
with respect to the Company Option divided by the total number of Acquiror
Shares subject to the new option (as determined under (A) immediately above),
rounded up to the nearest whole cent; provided, in the case of any Company
Option that would continue to qualify as an "incentive stock option" under
Section 422 of the Code, such adjustment shall be made in a manner consistent
with the requirements of Section 424(a) of the Code. If no such election is made
by the holder, the Company Option shall be treated as provided in (ii) above.

For purposes of the foregoing:

"TOTAL OPTION CONSIDERATION" means the Cash Consideration + (.4107 x the Meeting
Price)

"SPREAD" means
(Total Option Consideration - exercise price                   number of
                              per Company Share         x      Company Shares
                              of the Company Option)           subject to the
                                                               Company Option

         (b) Prior to the Effective Time, the Company and the Acquiror shall
take all actions (including amending the terms of any Company stock option or
compensation plan or


                                       10
<PAGE>   16

arrangement) necessary to give effect to the transactions contemplated by
Section 3.5(a), including obtaining all necessary consents.

         ARTICLE 3.6. EMPLOYEE STOCK PURCHASE PLAN.

         (a) The Company shall take all necessary action to provide that, not
later than five (5) Business Days prior to the Effective Time, (i) any
outstanding options to purchase Company Shares under the Company's Employee
Stock Purchase Plans (collectively, the "ESPP") shall terminate (the "ESPP
TERMINATION DATE"), and (ii) all amounts allocated to each participant's account
under the ESPP shall thereupon, at the election of the participant (x) be used
to purchase from the Company newly-issued whole Company Shares at a price equal
to the lower of 85% of (A) the closing price per Share on the first day of the
plan year, or (B) the ESPP Termination Date, or (y) returned to the participant,
and (iii) the ESPPs will terminate. At the Effective Time, any Company Shares so
purchased will be treated as provided in Section 3.2 of this Agreement. The
Company shall take all actions necessary so as not to allow participants to
increase the rate of their contributions to the ESSP.

         (b) Prior to the Effective Time, the Company shall take all actions
(including amending the terms of the ESPP) necessary to give effect to the
transactions contemplated by Section 3.6(a).

         ARTICLE 3.7. DISSENTING SHARES.

         (a) Notwithstanding any provision of this Agreement to the contrary,
Company Shares that are outstanding immediately prior to the Effective Time and
which are held by persons who shall not have voted in favor of this Agreement
and the Merger or consented thereto in writing and who shall have properly
demanded in writing appraisal for such shares in accordance with Section 262 of
the DGCL (collectively, the "DISSENTING SHARES") shall not be converted into or
represent the right to receive the Merger Consideration as provided hereunder.
Such persons shall be entitled to receive payment of the appraised value of such
Company Shares in accordance with the provisions of Section 262 of the DGCL,
except that all Dissenting Shares held by persons who shall have failed to
perfect or who effectively shall have withdrawn or lost their right to appraisal
of such shares under Section 262 shall thereupon be deemed to have been
converted into, as of the Effective Time, the right to receive the Merger
Consideration without any interest thereon upon surrender of the certificate
therefor in the manner provided hereunder.

         (b) The Company shall give Acquiror (i) prompt notice of any demands
for appraisal received by the Company, withdrawals of such demands and any other
instruments served pursuant to the DGCL and received by the Company and (ii) the
opportunity to participate in all negotiations and proceedings with respect to
demands for appraisal under the DGCL. The Company shall not, except with the
prior written consent of Acquiror, make any payment with respect to any demands
for appraisal or offer to settle or settle any such demands. All payments made

own funds and shall not be reimbursed by Acquiror or any Acquiror Subsidiary.

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

         Except as disclosed in (i) the Company Disclosure Schedule attached
hereto or (ii) the Company SEC Documents filed prior to the date hereof, the
Company represents and warrants to Acquiror as set forth below.

         ARTICLE 4.1. CORPORATE EXISTENCE AND POWER. The Company is a
corporation validly existing and in good standing under the laws of the State of
Delaware, and has all corporate powers and authority required to own, lease and
operate its assets and properties and to carry on its business as now conducted.
The Company is duly qualified to do business as a foreign corporation and is in
good standing in each jurisdiction where the character of the properties owned,
leased or operated by it or the nature of its activities makes qualification
necessary, except where the failure to be qualified or in good standing would
not be reasonably likely to have, individually or in the aggregate, a Company
Material Adverse Effect.

         ARTICLE 4.2. CORPORATE AUTHORIZATION. The execution, delivery and
performance by the Company of this Agreement and the consummation by the Company
of the transactions contemplated hereby are within the Company's corporate
powers and, except for the Company Stockholder Approval, have been duly
authorized by all necessary corporate action. Assuming that this Agreement
constitutes the valid and binding obligation of Acquiror, this Agreement
constitutes the valid and binding agreement of the Company, enforceable in
accordance with its terms.

         ARTICLE 4.3. GOVERNMENTAL AUTHORIZATION. The execution, delivery and
performance by the Company of this Agreement and the consummation by the Company
of the transactions contemplated hereby require no action by or in respect of,
or filing with, any Governmental Entity, other than (a) the filing of (i) a
certificate of merger in accordance with the DGCL and (ii) appropriate documents
with the relevant authorities of other states or jurisdictions in which the
Company is qualified to do business; (b) compliance with any applicable
requirements of the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (the

any applicable requirements of the Securities Act and the Exchange Act; (d) such
as may be required under any applicable state securities or blue sky laws; and
(e) such other consents, approvals, actions, orders, authorizations,
registrations, declarations and filings which, if not obtained or made, would
not be reasonably likely to have, individually or in the aggregate, a Company
Material Adverse Effect.

         ARTICLE 4.4. NON-CONTRAVENTION. The execution, delivery and performance
by the Company of this Agreement and the consummation by the Company of the
transactions contemplated hereby do not and will not (i) contravene or conflict
with the Company's or any Company Subsidiary's certificate of incorporation,
bylaws or any similar organizational documents, (ii) assuming compliance with
the matters referred to in Section 4.3, to the Knowledge of the Company
contravene or conflict with or constitute a violation of any provision of any
law, statute, ordinance, rule, regulation, judgment, injunction, order, writ,
permit, license or decree binding upon or applicable to the Company, any Company
Subsidiary or any of their respective properties or assets, (iii) violate,
conflict with or result in a breach of any provision of,


                                       12

or constitute a default (or an event which, with notice or lapse of time or
both, would constitute a default) under, or give rise to a right of, or result
in, the termination, cancellation, modification, acceleration or the loss of a
material benefit under any note, bond, mortgage, indenture, deed of trust,
concession, lease, contract or other instrument, obligation or agreement of any
kind or any license, franchise, permit or other similar authorization to which
the Company or any Company Subsidiary is a party or by which the Company or any
Company Subsidiary or any of their respective assets may be bound or affected,
or (iv) result in the creation or imposition of any Lien on any asset of the
Company or any Company Subsidiary, other than, in the case of each of (ii),
(iii) and (iv), any such items that would not, individually or in the aggregate,
be reasonably likely to have a Company Material Adverse Effect.

         ARTICLE 4.5. CAPITALIZATION.

         (a) The authorized capital stock of the Company consists of 300,000,000
Company Shares. As of the date hereof, (i) 71,506,544 Company Shares were issued
and outstanding (no Company Shares were held in treasury, and no Company Shares
were owned by any Company Subsidiary) and (ii) the Company had outstanding stock
options to purchase an aggregate of 6,848,427 Company Shares (all of which will

or voting securities of the Company or obligating the Company or any Company
Subsidiary to grant, extend or enter into any such agreement or commitment (the
items in clauses (i), (ii) and (iii) being referred to collectively as the

Rights Agreement dated as of April 16, 1997, between the Company and First Union
National Bank of North Carolina (the "COMPANY RIGHTS AGREEMENT"). There are no
outstanding obligations of the Company or any Company Subsidiary to repurchase,
redeem or otherwise acquire any Company Securities. There are no voting trusts,
proxies or other agreements or understandings to which the Company or any

<PAGE>   19

         ARTICLE 4.6. SUBSIDIARIES.

         (a) Each Company Subsidiary is a corporation duly incorporated or an
entity duly organized, and is validly existing and in good standing under the
laws of its jurisdiction of incorporation or organization, has all powers and
authority and all governmental licenses, authorizations, consents and approvals
required to own, lease and operate its assets and to carry on its business as
now conducted and is duly qualified to do business as a foreign corporation and
is in good standing in each jurisdiction where the character of the property
owned, leased or operated by it or the nature of its activities makes such
qualification necessary, in each case with exceptions which would not be
reasonably likely to have, individually or in the aggregate, a Company Material
Adverse Effect.

         (b) All of the outstanding shares of capital stock of, or other
ownership interest in, each Company Subsidiary have been validly issued and are
fully paid and nonassessable and free of statutory preemptive rights. All of the
outstanding capital stock of, or other ownership interest, which is owned,
directly or indirectly, by the Company in, each of its Subsidiaries is owned
free and clear of any Lien and free of any other limitation or restriction
(including any limitation or restriction on the right to vote, sell or otherwise
dispose of the stock or other ownership interests) with exceptions which would
not be reasonably likely to have, individually or in the aggregate, a Company
Material Adverse Effect. Except as set forth on the Company Disclosure Schedule,
there are no outstanding (i) shares of capital stock, debt securities or other
voting securities of the Company or any Company Subsidiary convertible into or
exchangeable or exercisable for shares of capital stock, debt securities or
voting securities or ownership interests in any Company Subsidiary, (ii)
subscriptions, calls, contracts, commitments, understandings, restrictions,
arrangements, warrants, options, or other rights to acquire from the Company or
any Company Subsidiary, or obligations of the Company or any Company Subsidiary
to issue, any capital stock, debt securities, voting securities or other
ownership interests in, or any securities convertible into or exchangeable or
exercisable for any capital stock, voting securities, debt securities or
ownership interests in, any Company Subsidiary, or obligations of the Company or
any Company Subsidiary to grant, extend or enter into any such agreement or
commitment, or (iii) obligations of the Company or any Company Subsidiary to
repurchase, redeem or otherwise acquire any outstanding securities of any
Company Subsidiary or any capital stock of, or other ownership interests in, any
Company Subsidiary.

         ARTICLE 4.7. COMPANY SEC DOCUMENTS.

         (a) The Company has made available to Acquiror the Company SEC
Documents. The Company has filed all reports, filings, registration statements
and other documents required to be filed by it with the SEC since June 30, 1998.
No Company Subsidiary is required under the Exchange Act or Securities Act to
file any form, report, registration statement or prospectus or other document
with the SEC.

         (b) As of its filing date, each Company SEC Document complied as to
form in all material respects with the applicable requirements of the Securities
Act and/or the Exchange Act, as the case may be.

         (c) No Company SEC Document filed since June 30, 1998 pursuant to the
Exchange Act contained, as of its filing date, any untrue statement of a
material fact or omitted to state any


                                       14
<PAGE>   20

material fact necessary in order to make the statements made therein, in the
light of the circumstances under which they were made, not misleading. No
Company SEC Document, as amended or supplemented, if applicable, filed since
June 30, 1998 pursuant to the Securities Act contained, as of the date on which
the document or amendment became effective, any untrue statement of a material
fact or omitted to state any material fact required to be stated therein or
necessary to make the statements therein not misleading.

         ARTICLE 4.8. FINANCIAL STATEMENTS; NO MATERIAL UNDISCLOSED LIABILITIES.

         (a) The audited consolidated financial statements and unaudited
consolidated interim financial statements of the Company included in the Company
10-Ks and the Company 10-Qs fairly present in all material respects, in
conformity with generally accepted accounting principles applied on a consistent
basis ("GAAP") (except as may be indicated in the notes thereto), the
consolidated financial position of the Company and its consolidated Subsidiaries
as of the dates thereof and their consolidated results of operations and changes
in financial position for the periods then ended (subject to normal year-end
adjustments in the case of any unaudited interim financial statements which in
the aggregate are not material).

         (b) As of the date of this Agreement, except as set forth in the
Company SEC Documents filed prior to the date hereof, neither the Company nor
any Company Subsidiary is party to or bound by (i) any "material contract" (as
such term is defined in Item 601(b)(10) of regulation S-K of the SEC) or (ii)
any non-competition agreement or any other agreement or arrangement that
similarly limits the Company or any Company Subsidiary.

         (c) There are no liabilities of the Company or any Company Subsidiary
of any kind whatsoever, whether accrued, contingent, absolute, determined,
determinable or otherwise, in each case, other than:

                  (i) liabilities or obligations disclosed in the Company
         Balance Sheet or the notes thereto;

                  (ii) liabilities or obligations incurred after June 30, 2000,
         in the ordinary course of business consistent with past practice which
         would not be reasonably likely to have, individually or in the
         aggregate, a Company Material Adverse Effect;

                  (iii) liabilities or obligations under this Agreement or
         incurred in connection with the transactions contemplated hereby; and

                  (iv) other liabilities or obligations, which would not be
         reasonably likely to have, individually or in the aggregate, a Company
         Material Adverse Effect.


                                       15
<PAGE>   21

         ARTICLE 4.9. INFORMATION TO BE SUPPLIED.

         (a) The information to be supplied by the Company for inclusion or
incorporation by reference in the Proxy Statement/Prospectus will (i) in the
case of the Registration Statement, at the time it becomes effective, not
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary in order to make the statements
therein not misleading and (ii) in the case of the remainder of the Proxy
Statement/Prospectus, at the time of the mailing thereof, at the time of the
Company Stockholder Meeting and at the time of the Acquiror Stockholder Meeting,
not contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary in order to make the
statements therein, in light of the circumstances under which they are made, not
misleading. The Proxy Statement/Prospectus will comply (with respect to
information relating to the Company) as to form in all material respects with
the provisions of the Securities Act and the Exchange Act.

         (b) Notwithstanding the foregoing, the Company makes no representation
or warranty with respect to any statements made or incorporated by reference in
the Proxy Statement/Prospectus based on information supplied by Acquiror for
inclusion or incorporation by reference therein.

         ARTICLE 4.10. ABSENCE OF CERTAIN CHANGES. Since June 30, 2000, except
as otherwise expressly contemplated by this Agreement, the Company and each of
its Subsidiaries have conducted their business in the ordinary course consistent
with past practice and there has not been (a) any damage, destruction or other
casualty loss (whether or not covered by insurance) affecting the business or
assets of the Company or any Company Subsidiary that would be reasonably likely
to have, individually or in the aggregate, a Company Material Adverse Effect,
(b) any action, event, occurrence, development, transaction, commitment,
dispute, change, violation, inaccuracy or other condition (financial or
otherwise) of any character (whether or not in the ordinary course of business)
that would be reasonably likely to have, individually or in the aggregate, a
Company Material Adverse Effect, or (c) any action prohibited by Section 6.1 of
this Agreement.

         ARTICLE 4.11. LITIGATION. There is no claim, action, suit,
investigation, arbitration or proceeding pending, or to the Knowledge of the
Company threatened, against, relating to or affecting the Company or any Company
Subsidiary or any of their respective assets or properties before any arbitrator
or Governmental Entity that would be reasonably likely to have, individually or
in the aggregate, a Company Material Adverse Effect. Neither the Company nor any
Company Subsidiary is subject to any judgment, decree, injunction, rule or order
of any arbitrator or Governmental Entity which prohibits or restricts the
consummation of the transactions contemplated hereby or has had or would be
reasonably likely to have, individually or in the aggregate, a Company Material
Adverse Effect.

         ARTICLE 4.12. TAXES. All material tax returns, statements, reports and
forms (collectively, the "COMPANY RETURNS") required to be filed with any taxing
authority by, or with respect to, the Company and the Company Subsidiaries have
been filed in accordance with all applicable laws; the Company and the Company
Subsidiaries have timely paid all taxes shown as due and payable on the Company
Returns that have been so filed, and, as of the time of filing, the Company
Returns correctly and completely reflected the facts regarding the income,
business, assets, operations, activities and the status of the Company and the
Company Subsidiaries (other


                                       16
<PAGE>   22

than taxes which are being contested in good faith and for which adequate
reserves are reflected on the Company Balance Sheet); the Company and the
Company Subsidiaries have made adequate provision for all taxes payable by them
for which no Company Return has yet been filed; the charges, accruals and
reserves for taxes with respect to the Company and its Subsidiaries reflected on
the Company Balance Sheet are adequate under GAAP to cover the tax liabilities
accruing through the date thereof; there is no action, suit, proceeding, audit
or claim now proposed or pending against or with respect to the Company or any
of the Company Subsidiaries in respect of any material amount of tax; neither
the Company nor any of the Company Subsidiaries has been a member of an
affiliated, consolidated, combined or unitary group, other than one of which the
Company was the common parent; neither the Company nor any Company Subsidiary is
a party to any tax allocation or sharing agreement; neither the Company nor any
Company Subsidiary has executed any outstanding waivers or comparable consents
regarding the application of the statute of limitations with respect to any
taxes or tax returns; and neither the Company nor any Company Subsidiary has
engaged in any transaction that could give rise to (i) a registration obligation
with respect to any Person under Section 6111 of the Code or the regulations
thereunder, (ii) a list maintenance obligation with respect to any Person under
Section 6112 of the Code or the regulations thereunder, or (iii) a disclosure
obligation as a "reportable transaction" under Section 6011 of the Code and the
regulations thereunder. The total adjusted basis for federal income tax purposes
of the assets to be transferred to Acquiror by the Company in the Merger will,
at the time of the Merger, equal or exceed the sum of the liabilities to be
assumed (within the meaning of ss.357(d) of the Code) by Acquiror.

         ARTICLE 4.13. EMPLOYEE BENEFITS.

         (a) With respect to each material "employee benefit plan", as defined
in Section 3(3) of the Employee Retirement Income Security Act of 1974
("ERISA"), each employment, severance or similar contract, plan, arrangement or
policy and each other plan or arrangement (written or oral) providing for
compensation, bonuses, profit-sharing, stock option or other stock related
rights or other forms of incentive or deferred compensation, vacation benefits,
insurance coverage (including any self-insured arrangements), health or medical
benefits, disability benefits, workers' compensation, supplemental unemployment
benefits, severance benefits and post-employment or retirement benefits
(including compensation, pension, health, medical or life insurance benefits)
which is maintained, administered or contributed to by the Company or any ERISA
Affiliate (as defined below) and covers any consultant, director, employee or
former employee of the Company or any Company Subsidiary, the Company has
delivered or will make available upon request copies of the plans (and, if
applicable, related trust agreements) and all amendments thereto and written
interpretations thereof to Acquiror together with the most recent annual report
(Form 5500 including, if applicable, Schedule B thereto) prepared in connection
with any plan. The material plans are referred to collectively herein as the
"COMPANY EMPLOYEE PLANS". An "ERISA AFFILIATE" of any Person means any other
Person which, together with such Person, would be treated as a single employer
under Section 414 of the Code.

         (b) With respect to each Company Employee Plan that constitutes a
"multiemployer plan", as defined in Section 3(37) of ERISA (a "MULTIEMPLOYER
PLAN"), or any other plan subject to Title IV of ERISA (a "RETIREMENT PLAN"), no
"accumulated funding deficiency", as


                                       17
<PAGE>   23

defined in Section 412 of the Code, has been incurred with respect to any
Company Employee Plan which is a Retirement Plan, whether or not waived. With
respect to any Company Employee Plans subject to Title IV of ERISA, the
actuarially determined present value of all "benefit liabilities" within the
meaning of Section 4001(a)(16) of ERISA (as determined on the basis of the
actuarial assumptions contained in the plans' most recent actuarial valuation)
did not exceed the then current value of the assets of such plans, and there has
not been an adverse change in the financial condition of such plans which would
have caused a material change in the funded status of such plans. To the
Knowledge of the Company, no condition exists and no event has occurred that
would be reasonably likely to constitute grounds for termination of any Company
Employee Plan which is a Retirement Plan or, with respect to any Company
Employee Plan which is a Multiemployer Plan, presents a material risk of a
complete or partial withdrawal under Title IV of ERISA and neither the Company
nor any of its ERISA Affiliates has incurred any liability under Title IV of
ERISA arising in connection with the termination of, or complete or partial
withdrawal from, any plan covered or previously covered by Title IV of ERISA
that would be reasonably likely to have, individually or in the aggregate, a
Company Material Adverse Effect. To the Knowledge of the Company, nothing has
been done or omitted to be done and no transaction or holding of any asset under
or in connection with any Company Employee Plan has occurred that will make the
Company or any Company Subsidiary, or any officer or director of the Company or
any Company Subsidiary, subject to any liability under Title I of ERISA or
liable for any tax pursuant to Section 4975 of the Code (assuming the taxable
period of any such transaction expired as of the date hereof) that would be
reasonably likely to have a Company Material Adverse Effect.

         (c) Each Company Employee Plan which is intended to be qualified under
Section 401(a) of the Code is so qualified and has been so qualified during the
period from its adoption to date, and each trust forming a part thereof is
exempt from tax pursuant to Section 501(a) of the Code. The Company has
furnished, or will make available upon request, to Acquiror copies of the most
recent Internal Revenue Service determination letters with respect to each
Company Employee Plan. Each Company Employee Plan has been maintained in
substantial compliance with its terms and with the requirements prescribed by
any and all statutes, orders, rules and regulations, including ERISA and the
Code, which are applicable to such Company Employee Plan.

         (d) There is no contract, agreement, plan or arrangement covering any
employee or former employee of the Company that, individually or collectively,
would be reasonably likely to give rise to the payment of any amount that would
not be deductible pursuant to the terms of Section 280G of the Code. The
execution of, and performance of the transactions contemplated in, this
Agreement will not (either alone or upon the occurrence of any additional or
subsequent events) constitute an event under any Company Employee Plan that will
result in any payment (whether of severance pay or otherwise), acceleration of,
forgiveness of indebtedness owing from, vesting of, distribution of, or increase
in or obligation to fund, any benefits with respect to any current or former
employee, director or consultant of the Company or any Company Subsidiary.

         (e) There has been no amendment to, written interpretation or
announcement (whether or not written) relating to, or change in employee
participation or coverage under, any Company Employee Plan which would increase
materially the expense of maintaining such Company


                                       18
<PAGE>   24

Employee Plan above the level of the expense incurred in respect thereof for the
fiscal year ended June 30, 2000.

         (f) Neither the Company nor any Company Subsidiary has any obligations
to provide retiree health and life insurance or other retiree death benefits
under any Company Employee Plan, other than benefits mandated by Section 4980B
of the Code or under applicable State law, and each such Company Employee Plan
may be amended or terminated without incurring liability thereunder.

         (g) To the Knowledge of the Company, no Company Employee Plan is
threatened with any dispute, lawsuit, claim (other than routine claims for
benefits), investigation or complaint to, or by, any Person or Governmental
Entity. No Company Employee Plan is the subject of an audit or, to the Knowledge
of the Company, under investigation by the Internal Revenue Service, the
Department of Labor, the Pension Benefit Guaranty Corporation or any other
Governmental Entity, nor, to the Knowledge of the Company, is any such audit or
investigation threatened.

         ARTICLE 4.14. LABOR MATTERS. There is no pending or, to the Knowledge
of the Company, threatened union organizational effort, material labor dispute,
strike or work stoppage against the Company or any Company Subsidiary or charge
or complaint against the Company or any Company Subsidiary by the National Labor
Relations Board or any similar Governmental Entity alleging any unfair labor
practice by the Company or any Company Subsidiary in connection with the
operation of their respective business. The Company and all Company Subsidiaries
have in the past been and are currently in compliance in all material respects
with all applicable collective bargaining agreements and laws respecting
employment, employment practices, labor relations, safety and health (other than
environmental), wages, hours and terms and conditions of employment. Neither the
Company nor any Company Subsidiary has experienced within the past 12 months a
"plant closing" or "mass layoff" within the meaning of the Worker Adjustment and
Retraining Notification Act, 29 U.S.C. ss.ss. 2101 et seq. Neither the execution
and delivery of this Agreement, nor the consummation by the Company of
transactions contemplated in accordance with the terms hereby will violate any
of the Company's or Company Subsidiaries' collective bargaining agreement(s)
with any labor organization(s).

         ARTICLE 4.15. COMPLIANCE WITH LAWS; LICENSES, PERMITS AND
REGISTRATIONS.

         (a) Neither the Company nor any Company Subsidiary is in violation of,
or has violated, any applicable provisions of any laws, statutes, ordinances,
regulations, judgments, injunctions, orders or consent decrees, except for
violations which would not be reasonably likely to have, individually or in the
aggregate, a Company Material Adverse Effect.

         (b) The Company and each Company Subsidiary has been and is in
compliance with all permits, licenses, franchises, variances, exceptions,
orders, consents, approvals, authorizations of and registrations with and under
all federal, state, local and foreign laws, and from all Governmental Entities
required by the Company and each of its Subsidiaries to carry on their
respective businesses as currently conducted, except where the failure to have
or be in compliance with the permits, licenses, franchises, variances,
exceptions, orders, consents, approvals, authorizations or registrations would
not be reasonably likely to have, individually or in the aggregate, a Company
Material Adverse Effect.


                                       19
<PAGE>   25

         (c) The Company and each Company Subsidiary are, to the extent
applicable to their operations, certified for participation or enrollment in the
Medicare and Medicaid programs, have a current and valid provider contract with
the Medicare and Medicaid programs, are in substantial compliance with the
conditions of participation of such programs and have received all approvals or
qualifications necessary for capital reimbursement of the Company's and its
Subsidiaries' assets, except where the failure to be so certified, to have such
contracts, to be in such compliance or to have such approvals or qualifications
would not be reasonably likely to have, individually or in the aggregate, a
Company Material Adverse Effect. Neither the Company nor any Company Subsidiary
has received notice from the regulatory authorities which enforce the statutory
or regulatory provisions in respect of either the Medicare or Medicaid program
of any pending or threatened investigations, and neither the Company nor any of
its Subsidiaries has any reason to believe that any such investigations or
surveys are pending, threatened or imminent which may have, individually or in
the aggregate, a Company Material Adverse Effect.

         ARTICLE 4.16. TITLE TO PROPERTIES.

         (a) The Company and each Company Subsidiary have good and marketable
title to, or valid leasehold interests in, all their properties and assets,
except for those which are no longer used or useful in the conduct of their
businesses, except for defects in title, easements, restrictive covenants and
similar Liens, encumbrances or impediments that (i) are not substantial in
character, amount or extent and do not detract from the value, or interfere with
the present use of the property subject thereto or affected thereby or otherwise
impair the Company's or any Company Subsidiary's business operations and (ii) in
the aggregate, would not be reasonably likely to have, individually or in the
aggregate, a Company Material Adverse Effect. All of these assets and
properties, other than assets and properties in which the Company or any of its
Subsidiaries has leasehold interests, are free and clear of all Liens, except
for Liens that, in the aggregate, would not have a Company Material Adverse
Effect.

         (b) Except as would not be reasonably likely to have a Company Material
Adverse Effect, (i) the Company and each of its Subsidiaries are in compliance
with the terms of all leases to which they are a party and under which they are
in occupancy, and all such leases are in full force and effect and (ii) the
Company and each of its Subsidiaries enjoy peaceful and undisturbed possession
under all such leases.

         ARTICLE 4.17. INTELLECTUAL PROPERTY. Except as would not be reasonably
likely to have, individually or in the aggregate, a Company Material Adverse
Effect, the Company and each of its Subsidiaries own or have a valid license to
use each trademark, service mark, trade name, mask work, invention, patent,

ownership interest in, each Acquiror Subsidiary have been validly issued and are
fully paid and nonassessable and free of statutory preemptive rights. All of the

dispose of the stock or other ownership interests) with exceptions which would
not be reasonably likely to have, individually or in the aggregate, an Acquiror
Material Adverse Effect. Except as set forth on the Acquiror Disclosure

Acquiror SEC Documents filed prior to the date hereof, neither the Acquiror nor
any Acquiror Subsidiary is party to or bound by (i) any "material contract" (as

any kind whatsoever, whether accrued, contingent, absolute, determined,

         which would not be reasonably likely to have, individually or in the
         aggregate, an Acquiror Material Adverse Effect;

         reasonably likely to have, individually or in the aggregate, an
         Acquiror Material Adverse Effect.

         ARTICLE 5.9. INFORMATION TO BE SUPPLIED.

         (a) The information to be supplied by Acquiror for inclusion or
incorporation by reference in the Proxy Statement/Prospectus will (i) in the
case of the Registration Statement, at the time it becomes effective, not

of its Subsidiaries have conducted their business in the ordinary course
consistent with past practice and there has not been (a) any damage, destruction
or other casualty loss (whether or not covered by insurance) affecting the
business or assets of Acquiror or any Acquiror Subsidiary that would be
reasonably likely to have, individually or in the aggregate, an Acquiror
Material Adverse Effect or (b) any action, event, occurrence, development,
transaction, commitment, dispute, change, violation, inaccuracy or other
condition (financial or otherwise) of any character (whether or not in the
ordinary course of business) that would be reasonably likely to have,
individually or in the aggregate, an Acquiror Material Adverse Effect, or (c)
any action prohibited by Section 7.1 of this Agreement.

or Governmental Entity that would be reasonably likely to have, individually or
in the aggregate, an Acquiror Material Adverse Effect. Neither the Acquiror nor
any Acquiror Subsidiary is subject to any judgment, decree, injunction, rule or
order of any arbitrator or Governmental Entity which prohibits or restricts the
consummation of the transactions contemplated hereby or has had or would be
reasonably likely to have, individually or in the aggregate, an Acquiror
Material Adverse Effect.

<PAGE>   33

applicable laws; Acquiror and the Acquiror Subsidiaries have timely paid all
taxes shown as due and payable on the Acquiror Returns that have been so filed,
and, as of the time of filing, the Acquiror Returns correctly and completely
reflected the facts regarding the income, business, assets, operations,
activities and the status of Acquiror and the Acquiror Subsidiaries (other than
taxes which are being contested in good faith and for which adequate reserves
are reflected on the Acquiror Balance Sheet); Acquiror and the Acquiror
Subsidiaries have made adequate provision for all taxes payable by them for
which no Acquiror Return has yet been filed; the charges, accruals and reserves
for taxes with respect to Acquiror and its Subsidiaries reflected on the
Acquiror Balance Sheet are adequate under GAAP to cover the tax liabilities
accruing through the date thereof; there is no action, suit, proceeding, audit
or claim now proposed or pending against or with respect to Acquiror or any of

affiliated, consolidated, combined or unitary group, other than one of which
Acquiror was the common parent; neither the Acquiror nor any Acquiror Subsidiary
is a party to any tax allocation or sharing agreement; neither the Acquiror nor
any Acquiror Subsidiary has executed any outstanding waivers or comparable
consents regarding the application of the statute of limitations with respect to

obligation with respect to any Person under Section 6111 of the Code or the
regulations thereunder, (ii) a list maintenance obligation with respect to any
Person under Section 6112 of the Code or the regulations thereunder, or (iii) a
disclosure obligation as a "reportable transaction" under Section 6011 of the
Code and the regulations thereunder.

         ARTICLE 5.13. EMPLOYEE BENEFITS.

         (a) With respect to each material "employee benefit plan", as defined
in Section 3(3) of ERISA, each employment, severance or similar contract, plan,
arrangement or policy and each other plan or arrangement (written or oral)
providing for compensation, bonuses, profit-sharing, stock option or other stock
related rights or other forms of incentive or deferred compensation, vacation
benefits, insurance coverage (including any self-insured arrangements), health
or medical benefits, disability benefits, workers' compensation, supplemental
unemployment benefits, severance benefits and post-employment or retirement
benefits (including compensation, pension, health, medical or life insurance
benefits) which is maintained, administered or contributed to by Acquiror or any
ERISA Affiliate and covers any consultant, director, employee or former employee
of Acquiror or any Acquiror Subsidiary, Acquiror has delivered or will make
available upon request copies of the plans (and, if applicable, related trust
agreements) and all amendments thereto and written interpretations thereof to
the Company together with the most recent annual report (Form 5500 including, if
applicable, Schedule B thereto) prepared in connection with any plan. The
material plans are referred to collectively herein as the "ACQUIROR EMPLOYEE
PLANS".

         (b) With respect to each Acquiror Employee Plan that constitutes a
Multiemployer Plan or any Retirement Plan, no "accumulated funding deficiency",
as defined in Section 412 of the Code, has been incurred with respect to any
Acquiror Employee Plan which is a Retirement Plan, whether or not waived. With
respect to any Acquiror Employee Plans subject to Title IV of ERISA, the
actuarially determined present value of all "benefit liabilities" within the
meaning of Section 4001(a)(16) of ERISA (as determined on the basis of the
actuarial assumptions contained


                                       28
<PAGE>   34

in the plans' most recent actuarial valuation) did not exceed the then current
value of the assets of such plans, and there has not been an adverse change in
the financial condition of such plans which would have caused a material change
in the funded status of such plans. To the Knowledge of Acquiror, no condition
exists and no event has occurred that would be reasonably likely to constitute
grounds for termination of any Acquiror Employee Plan which is a Retirement Plan
or, with respect to any Acquiror Employee Plan which is a Multiemployer Plan,
presents a material risk of a complete or partial withdrawal under Title IV of
ERISA and neither Acquiror nor any of its ERISA Affiliates has incurred any
liability under Title IV of ERISA arising in connection with the termination of,
or complete or partial withdrawal from, any plan covered or previously covered
by Title IV of ERISA that would be reasonably likely to have, individually or
in the aggregate, an Acquiror Material Adverse Effect. To the Knowledge of
Acquiror, nothing has been done or omitted to be done and no transaction or
holding of any asset under or in connection with any Acquiror Employee Plan has
occurred that will make Acquiror or any Acquiror Subsidiary, or any officer or
director of the Acquiror or any Acquiror Subsidiary, subject to any liability
under Title I of ERISA or liable for any tax pursuant to Section 4975 of the
Code (assuming the taxable period of any such transaction expired as of the date
hereof) that would be reasonably likely to have, individually or in the
aggregate, an Acquiror Material Adverse Effect.

         (c) Each Acquiror Employee Plan which is intended to be qualified under
Section 401(a) of the Code is so qualified and has been so qualified during the
period from its adoption to date, and each trust forming a part thereof is
exempt from tax pursuant to Section 501(a) of the Code. Acquiror has furnished,
or will make available upon request, to the Company copies of the most recent
Internal Revenue Service determination letters with respect to each Acquiror
Employee Plan. Each Acquiror Employee Plan has been maintained in substantial
compliance with its terms and with the requirements prescribed by any and all
statutes, orders, rules and regulations, including ERISA and the Code, which are
applicable to such Acquiror Employee Plan.

         (d) There is no contract, agreement, plan or arrangement covering any
employee or former employee of Acquiror that, individually or collectively,
would be reasonably likely to give rise to the payment of any amount that would
not be deductible pursuant to the terms of Section 280G of the Code. The
execution of, and performance of the transactions contemplated in, this
Agreement will not (either alone or upon the occurrence of any additional or
subsequent events) constitute an event under any Acquiror Employee Plan that
will result in any payment (whether of severance pay or otherwise), acceleration
of, forgiveness of indebtedness owing from, vesting of, distribution of, or
increase in or obligation to fund, any benefits with respect to any current or
former employee, director or consultant of the Acquiror or any Acquiror
Subsidiary.

         (e) There has been no amendment to, written interpretation or
announcement (whether or not written) relating to, or change in employee
participation or coverage under, any Acquiror Employee Plan which would increase
materially the expense of maintaining such Acquiror Employee Plan above the
level of the expense incurred in respect thereof for the fiscal year ended
December 31, 1999.

         (f) Neither Acquiror nor any Acquiror Subsidiary has any obligations to
provide retiree health and life insurance or other retiree death benefits under
any Acquiror Employee Plan, other


                                       29
<PAGE>   35

than benefits mandated by Section 4980B of the Code or under applicable State
law, and each such Acquiror Employee Plan may be amended or terminated without
incurring liability thereunder.

         (g) To the Knowledge of Acquiror, no Acquiror Employee Plan is
threatened with any dispute, lawsuit, claim (other than routine claims for
benefits), investigation or complaint to, or by, any Person or Governmental
Entity. No Acquiror Employee Plan is the subject of an audit or, to the
Knowledge of Acquiror, under investigation by the Internal Revenue Service, the
Department of Labor, the Pension Benefit Guaranty Corporation or any other
Governmental Entity, nor, to the Knowledge of Acquiror, is any such audit or
investigation threatened.

         ARTICLE 5.14. LABOR MATTERS. There is no pending or, to the Knowledge
of Acquiror, threatened union organizational effort, material labor dispute,
strike or work stoppage against Acquiror or any Acquiror Subsidiary or charge or
complaint against Acquiror or any Acquiror Subsidiary by the National Labor
Relations Board or any similar Governmental Entity alleging any unfair labor
practice by Acquiror or any Acquiror Subsidiary in connection with the operation
of their respective business. Acquiror and all Acquiror Subsidiaries have in the
past been and are currently in compliance in all material respects with all
applicable collective bargaining agreements and laws respecting employment,
employment practices, labor relations, safety and health (other than
environmental), wages, hours and terms and conditions of employment. Neither
Acquiror nor any Acquiror Subsidiary has experienced within the past 12 months a
"plant closing" or "mass layoff" within the meaning of the Worker Adjustment and
Retraining Notification Act, 29 U.S.C. ss.ss. 2101 et seq. Neither the execution
and delivery of this Agreement, nor the consummation by Acquiror of transactions
contemplated in accordance with the terms hereby will violate any of Acquiror's
or Acquiror Subsidiaries' collective bargaining agreement(s) with any labor
organization(s).

         ARTICLE 5.15. COMPLIANCE WITH LAWS; LICENSES, PERMITS AND
REGISTRATIONS.

         (a) Neither Acquiror nor any Acquiror Subsidiary is in violation of, or
has violated, any applicable provisions of any laws, statutes, ordinances,
regulations, judgments, injunctions, orders or consent decrees, except for
violations which would not be reasonably likely to have, individually or in the
aggregate, an Acquiror Material Adverse Effect.

         (b) Acquiror and each Acquiror Subsidiary has been and is in compliance
with all permits, licenses, franchises, variances, exceptions, orders, consents,
approvals, authorizations of and registrations with and under all federal,
state, local and foreign laws, and from all Governmental Entities required by
Acquiror and each Acquiror Subsidiary to carry on their respective businesses as
currently conducted, except where the failure to have or be in compliance with
the permits, licenses, franchises, variances, exceptions, orders, consents,
approvals, authorizations or registrations would not be reasonably likely to
have, individually or in the aggregate, an Acquiror Material Adverse Effect.

         (c) Acquiror and each Acquiror Subsidiary are, to the extent applicable
to their operations, certified for participation or enrollment in the Medicare
and Medicaid programs, have a current and valid provider contract with the
Medicare and Medicaid programs, are in substantial compliance with the
conditions of participation of such programs and have received all approvals or
qualifications necessary for capital reimbursement of Acquiror's and the


                                       30
<PAGE>   36

Acquiror's Subsidiaries' assets, except where the failure to be so certified, to
have such contracts, to be in such compliance or to have such approvals or
qualifications would not be reasonably likely to have, individually or in the
aggregate, an Acquiror Material Adverse Effect. Neither Acquiror nor any
Acquiror Subsidiary has received notice from the regulatory authorities which
enforce the statutory or regulatory provisions in respect of either the Medicare
or Medicaid program of any pending or threatened investigations, and neither
Acquiror nor any Acquiror Subsidiary has any reason to believe that any such
investigations or surveys are pending, threatened or imminent which may have,
individually or in the aggregate, an Acquiror Material Adverse Effect.

         ARTICLE 5.16. TITLE TO PROPERTIES.

         (a) Acquiror and each Acquiror Subsidiary have good and marketable
title to, or valid leasehold interests in, all their properties and assets,
except for those which are no longer used or useful in the conduct of their
businesses, except for defects in title, easements, restrictive covenants and
similar Liens, encumbrances or impediments that (i) are not substantial in
character, amount or extent and do not detract from the value, or interfere with
the present use of the property subject thereto or affected thereby or otherwise
impair Acquiror's or any Acquiror Subsidiary's business operations and (ii) in
the aggregate, would not be reasonably likely to have, individually or in the
aggregate, an Acquiror Material Adverse Effect. All of these assets and
properties, other than assets and properties in which Acquiror or any Acquiror
Subsidiary has leasehold interests, are free and clear of all Liens, except for
Liens that, in the aggregate, would not have an Acquiror Material Adverse
Effect.

         (b) Except as set forth on the Acquiror Disclosure Schedule or as would
not be reasonably likely to have an Acquiror Material Adverse Effect, (i)
Acquiror and each Acquiror Subsidiary are in compliance with the terms of all
leases to which they are a party and under which they are in occupancy, and all
of these leases are in full force and effect and (ii) Acquiror and each Acquiror
Subsidiary enjoy peaceful and undisturbed possession under all such leases.

         ARTICLE 5.17. INTELLECTUAL PROPERTY. Except as would not be reasonably
likely to have, individually or in the aggregate, an Acquiror Material Adverse
Effect, Acquiror and the Acquiror Subsidiaries own or have a valid license to
use each trademark, service mark, trade name, mask work, invention, patent,
trade secret, copyright, know-how (including any registrations or applications
for registration of any of the foregoing) or any other similar type of
proprietary intellectual property right (collectively, the "ACQUIROR
INTELLECTUAL PROPERTY") necessary to carry on the business of Acquiror and the
Acquiror Subsidiaries, taken as a whole, as currently conducted. Neither
Acquiror nor any Acquiror Subsidiary has received any written notice of
infringement of or challenge to the validity or enforceability of, and, to
Acquiror's Knowledge, there are no claims pending with respect to the rights of
others to the use of, any Acquiror Intellectual Property that, in any case,
would be reasonably likely to have, individually or in the aggregate, an
Acquiror Material Adverse Effect. To Acquiror's Knowledge, there is no basis for
any such claims. To the Acquiror's Knowledge, no other person is infringing any
Acquiror Intellectual Property, except such infringement as would not have,
individually or in the aggregate, an Acquiror Material Adverse Effect. Neither
Acquiror nor any Acquiror Subsidiary, nor the respective businesses thereof as
currently conducted, violates or infringes the intellectual property or
proprietary rights of any other Person, except such violations and


                                       31
<PAGE>   37

infringements as would not have, individually or in the aggregate, an Acquiror
Material Adverse Effect.

         ARTICLE 5.18. FINDERS' FEES; OPINION OF FINANCIAL ADVISOR.

         (a) Except pursuant to and in accordance with the terms of the
agreement with Merrill Lynch, Pierce, Fenner & Smith Incorporated, whose fees
will be paid by Acquiror, and except for fees paid pursuant to the Commitment
Letters referenced in Section 5.20, there is no investment banker, broker,
finder or other intermediary which has been retained by, or is authorized to act
on behalf of Acquiror or any Acquiror Subsidiary which might be entitled to any
fee or commission from, the Company, any Company Subsidiary, Acquiror or any of
its Affiliates in connection with or upon consummation of the transactions
contemplated by this Agreement.

         (b) Acquiror has received the opinion of Merrill Lynch, Pierce, Fenner
& Smith Incorporated, to the effect that, as of the date hereof and subject to
the qualifications stated therein, the Merger is fair to the Acquiror from a
financial point of view.

         ARTICLE 5.19. REQUIRED VOTE; BOARD RECOMMENDATION.

         (a) The only vote of the holders of any class or series of capital
stock of Acquiror required by law, rule or regulation to approve this Agreement,
the Merger and/or any of the other transactions contemplated hereby are the
affirmative vote of the holders of a majority of the Acquiror Shares present and
voting at the Acquiror Stockholder Meeting (as defined in Section 7.2) in favor

Section 251 of the DGCL and (iii) resolved to recommend to such stockholders
that they vote in favor of adopting and approving this Agreement and the Merger
and the issuance of the Acquiror Shares pursuant to the Merger in accordance
with the terms hereof.

         ARTICLE 5.20. STATE TAKEOVER STATUTES. Acquiror has taken all actions
required to be taken by it in order to exempt this Agreement and the
transactions contemplated hereby and thereby from the provisions of Section 203
of the DGCL, and accordingly, that section does not apply to the Merger or any
of the transactions contemplated hereby. No other "control share acquisition",
"fair price" or other anti-takeover laws or regulations enacted under state or
federal laws in the United States apply to this Agreement or any of the
transactions contemplated hereby and thereby.

         ARTICLE 5.21. ACQUIROR'S STOCKHOLDER RIGHTS PLAN. The Board of
Directors of Acquiror has complied with or amended the Acquiror Rights Agreement
in accordance with its terms to render it inapplicable to the transactions
contemplated by this Agreement. Acquiror has


                                       32

as amended, in effect as of execution and delivery of this Agreement.

policies and binders of all insurance covering all material assets, business,
equipment, properties, operations, employees, officers and directors of Acquiror
and the Acquiror Subsidiaries have been made available for inspection by the
Company. The coverage under each such policy and binder is in full force and
effect, and no notice of cancellation or non-renewal has been received by
Acquiror or any Acquiror Subsidiary.

         ARTICLE 5.23. AGREEMENTS AND COMMITMENTS. Neither Acquiror nor any
Acquiror Subsidiary, nor, to the Knowledge of Acquiror, any other party, is in
breach or violation of, or in default in the performance or observance of any
term or provision of (and no event has occurred which, with lapse of time or
notice by a third party, would result in a breach or violation of, or the
default under, or give rise to any right of termination, amendment,
cancellation, acceleration or loss of benefits or result in the creation of any
lien upon any of the properties or assets of Acquiror or any Acquiror Subsidiary
under), any contract to which Acquiror or any Acquiror Subsidiary is a party or
by which it or any of its properties or assets are bound, other than breaches,
violations and defaults which have not had and would not be reasonably likely to
have, individually or in the aggregate, an Acquiror Material Adverse Effect.

         ARTICLE 5.24. AFFILIATE AGREEMENTS. There are no material oral or
written agreements or transactions between Acquiror or any Acquiror Subsidiary
on the one hand, and any (i) officer or director of Acquiror or any Acquiror
Subsidiary, (ii) record or beneficial owner of five percent or more of the
voting securities of Acquiror or (iii) to the Knowledge of Acquiror, an
Affiliate of any such officer, director or beneficial owner, on the other hand,
other than payment of compensation for services rendered in the ordinary course
of employment for Acquiror or any Acquiror Subsidiary.

         ARTICLE 5.25. ENVIRONMENTAL MATTERS. Except as would not be reasonable

conditions involving Acquiror or any of the Acquiror Subsidiaries (including,
without limitation, any Release or threatened Release of any Hazardous Substance

         ARTICLE 6.3. ACQUISITION PROPOSALS; BOARD RECOMMENDATION.

         (a) The Company agrees that it shall not, nor shall it permit any
Company Subsidiary to, nor shall it authorize or knowingly permit any officer,
director, employee, investment banker, attorney, accountant, agent or other
advisor or representative of the Company or any Company Subsidiary
("REPRESENTATIVES"), directly or indirectly, to and it shall use reasonable best
efforts to cause such persons not to (i) solicit, initiate or encourage any
inquiries or the making of any proposal or offer with respect to any Acquisition

Representatives to, furnish or cause to be furnished information and may
participate in negotiations and discussions with respect to any Acquisition
Proposal, which the Company's Board of Directors determines in good faith, after
consulting with its outside counsel and its financial advisors, is reasonably
likely to lead to the delivery of a Superior Proposal, (B) the Company's Board
of Directors may take the actions described in the last sentence of Section 6.2,
(C) the Company's Board of Directors may recommend an Acquisition Proposal to
Company Stockholders and (D) the Company may terminate this Agreement pursuant

agreement with respect to such Acquisition Proposal, in each case, if the
Company's Board of Directors determines, in good faith after consulting with its
outside counsel and its financial advisors, that such action is necessary to
comply with its fiduciary duties under applicable law; provided that such
Acquisition Proposal was not solicited in violation of this Section 6.3, and in
the case of (B), (C) or (D) there exists an Acquisition Proposal which
constitutes a Superior Proposal; provided, further, that prior to furnishing
non- public information to any such party, the Company shall have entered into a
confidentiality agreement no less favorable to the Company than the
Confidentiality Agreement between the Company and the Acquiror dated July 17,
2000.

         (b) The Company agrees that it will immediately cease and cause to be
terminated any existing activities, discussions or negotiations with any parties
conducted heretofore with respect to any proposed Acquisition Proposal.

         (c) Unless the Company's Board of Directors has previously withdrawn,
or is concurrently therewith withdrawing, the Company Recommendation in
accordance with Section 6.2, neither the Company's Board of Directors nor any
committee thereof shall recommend any Acquisition Proposal to the Company
Stockholders. Notwithstanding the foregoing, nothing contained in this Section
6.3(b) or elsewhere in this Agreement shall prevent the Company's Board of
Directors from complying with Rule 14e-2 under the 1934 Act with respect to any

Proposal or any request for nonpublic information or for access to the
properties, books or records of the Company or any

amendments) of any Acquisition Proposal or request.

shall use its reasonable best efforts to cause each person who is an Affiliate
of the Company to execute a written agreement on or prior to Closing in
substantially the form of Exhibit B hereto ("AFFILIATE LETTERS"). Acquiror shall
be entitled to place legends as specified in such Affiliate Letters on the
certificates evidencing any Acquiror Shares to be received by such Affiliates of

         The Acquiror agrees as set forth below.

         ARTICLE 7.1. ACQUIROR INTERIM OPERATIONS. Except as set forth in the
Acquiror Disclosure Schedule or as otherwise expressly contemplated hereby,
without the prior consent of the Company (which consent shall not be
unreasonably withheld or delayed), from the date hereof until the Effective
Time, Acquiror shall and shall cause each of the Acquiror Subsidiaries to,
conduct their business in all material respects in the ordinary course
consistent with past practice and shall use commercially reasonable efforts to
(i) preserve intact its present business organization, (ii) maintain in effect
all material foreign, federal, state and local licenses, approvals and
authorizations, including, without limitation, all material licenses and permits
that are required for Acquiror or any Acquiror Subsidiary to carry on its
business and (iii) preserve existing relationship with its material customers,
lenders, suppliers and others having material business relationships with it;
provided, however, that in each case, the Acquiror shall not be held responsible
for any change or development relating to (w) U.S. or global economic or
industry conditions, (x) changes in U.S. or global financial markets or
conditions, (y) any generally applicable change in law, rule or regulation or
GAAP or interpretation of any thereof and/or (z) the announcement of this
Agreement or the transactions contemplated hereby. Without limiting the
generality of the foregoing, except as otherwise expressly contemplated by this
Agreement, from the date hereof until the Effective Time, without the prior
consent of the Company (which consent shall not be unreasonably withheld or
delayed), Acquiror shall not, nor shall it permit any Acquiror Subsidiary to:


                                       39
<PAGE>   45

         (a) make any amendment to Acquiror's certificate of incorporation that
changes any material term or provision of the Acquiror Shares;

         (b) engage in any material repurchase at a premium, recapitalization,
restructuring or reorganization with respect to Acquiror's capital stock,
including, without limitation, by way of any extraordinary dividend on, or other
extraordinary distributions with respect to, Acquiror's capital stock;

         (c) acquire by merging or consolidating with, or by purchasing a
substantial portion of the assets of or equity in, or by any other manner, any
Person or any business or division thereof, other than Triad Hospitals Holdings,
Inc., or otherwise acquire any assets, unless Acquiror concludes in good faith
that such acquisition or the entering into of a definitive agreement relating to
or the consummation of such transaction would not (i) impose any material delay
in the obtaining of, or significantly increase the risk of not obtaining, any
authorizations, consents, orders, declarations or approvals of any Governmental
Entity necessary to consummate the Merger or the expiration or termination of
any applicable waiting period, (ii) significantly increase the risk of any
Governmental Entity entering an order prohibiting the consummation of the Merger
or (iii) significantly increase the risk of not being able to remove any such
order on appeal or otherwise; or

         (d)  agree, resolve or otherwise commit to do any of the foregoing.

         ARTICLE 7.2. STOCKHOLDER MEETING; BOARD RECOMMENDATION. Acquiror shall
cause a meeting of its Stockholders (the "ACQUIROR STOCKHOLDER MEETING") to be
duly called and held as close as reasonably practicable to the date on which all
of the other conditions to the Closing, as specified in Article 9, are expected
to be satisfied, for the purpose of obtaining the Acquiror Stockholder Approval.
Pursuant thereto, (i) Acquiror's Board of Directors shall recommend (the
"ACQUIROR RECOMMENDATION") approval and adoption by its Stockholders of the
issuance of Acquiror Shares pursuant to the Merger, (ii) neither Acquiror's
Board of Directors nor any committee thereof shall amend, modify, withdraw,
condition or qualify the Acquiror Recommendation in a manner adverse to the
Company or take any action or make any statement inconsistent with the Acquiror
Recommendation and (iii) Acquiror shall take all lawful action to solicit the
Acquiror Stockholder Approval.

         ARTICLE 7.3.  DIRECTOR AND OFFICER LIABILITY.

         (a) CONTINUING PROTECTION. Acquiror and the Surviving Corporation agree
that the Surviving Corporation shall adopt prior to the Effective Time, in its
Certificate of Incorporation and bylaws, the same indemnification, limitation of
or exculpation from liability and expense advancement provisions as those set
forth in the Company's certificate of incorporation and bylaws, in each case as
of the date of this Agreement, and that such provisions shall not be amended,
repealed, revoked or otherwise modified for a period of six (6) years after the
Effective Time in any manner that would adversely affect the rights thereunder
of the individuals who on or prior to the Effective Time were directors,
officers, employees or agents of the Company or the Company Subsidiaries or are
otherwise entitled to the benefit of such provisions.

         (b) INDEMNIFICATION. To the fullest extent permitted under applicable
law, after the Effective Time, Acquiror shall, and Acquiror shall cause the
Surviving Corporation to,


                                       40
<PAGE>   46

indemnify, defend and hold harmless, each present and former director or officer
of the Company and each Company Subsidiary and each Person entitled to
indemnification under the Certificate of Incorporation or Bylaws of the
Surviving Corporation (collectively, the "INDEMNIFIED PARTIES") against all
costs and expenses (including reasonable attorneys' fees), judgments, fines,
losses, claims, damages, liabilities and settlement amounts paid in connection
with any claim, action, suit, proceeding or investigation (whether arising
before or after the Effective Time), arising out of or pertaining to any action
or omission in their capacity as director, officer, trustee, partner or
fiduciary in each case occurring on or before the Effective Time (including the
transactions contemplated by this Agreement). Without limiting the foregoing, in
the event of any claim, action, suit, proceeding or investigation, (i) Acquiror
and the Surviving Corporation shall (x) periodically advance reasonable fees and
expenses (including attorneys fees) with respect to the foregoing, (y) pay the
reasonable fees and expenses of counsel selected by each Indemnified Party which
counsel shall be reasonably satisfactory to the Surviving Corporation, promptly
after statements therefor are received and (z) vigorously assist each
Indemnified Party in such defense, and (ii) Acquiror and the Surviving
Corporation, as applicable, shall cooperate in the defense of any matter;
provided, however, that Acquiror and the Surviving Corporation shall not be
liable for any settlement effected without its prior written consent (which
consent shall not be unreasonably withheld or delayed).

         (c) INSURANCE. For six (6) years from the Effective Time, the Surviving
Corporation shall, and the Acquiror shall cause the Surviving Corporation to,
provide to the Company's and each Company Subsidiary's directors and officers
liability and fiduciary liability insurance protection with substantially the
same coverage and in substantially the same amount, and on terms no less
favorable to the directors and officers than, that provided by the Company's
directors' and officers' liability insurance policies in effect on the date
hereof; provided, however, that the Surviving Corporation shall be obligated to
purchase and maintain such insurance only to the extent such insurance is
available; and provided, further, the Surviving Corporation shall not be
required in order to maintain or procure such coverage to pay an annual premium
in excess of 150% of the current annual premium paid by the Company for its
existing coverage (the "CAP"). If equivalent coverage cannot be obtained, or can
be obtained only by paying an annual premium in excess of the Cap, Acquiror
shall only be required to obtain as much coverage as can be obtained by paying
an annual premium equal to the Cap. With the Acquiror's consent, which consent
shall not be unreasonably withheld, the Company may purchase such insurance
prior to the Closing on a prepaid noncancellable basis, so long as the premium
does not exceed six times the Cap.

         ARTICLE 7.4. EMPLOYEE BENEFITS. For one (1) year from the Effective
Time, Acquiror shall provide (or shall cause the Surviving Corporation to
provide) employees of the Company and the Company Subsidiaries with salary and
benefits under employee benefit plans that are comparable in the aggregate than
those currently provided by the Company and the Company Subsidiaries to its
employees (including benefits pursuant to qualified and nonqualified retirement
plans, savings plans, medical, dental, disability and life insurance plans and
programs, deferred compensation arrangements, bonus and retiree benefit plans,
policies and arrangements). For purposes of any employee benefit plan or
arrangement maintained by Acquiror or any Acquiror Subsidiary, Acquiror shall
recognize (or cause to be recognized), as vesting and eligibility service, any
service with the Company and its Subsidiaries and any predecessor


                                       41
<PAGE>   47

entities under similar benefit plans (and any other service credited by the
Company under similar benefit plans). In addition, such service shall be
recognized for benefit accrual purposes under any vacation and severance plans
of Acquiror or any Acquiror Subsidiary; provided, however, that solely to the
extent necessary to avoid duplication of benefits, amounts payable under
employee benefit plans provided by Acquiror or an Acquiror Subsidiary may be
reduced by amounts payable under similar Company Employee Plans with respect to
the same periods of service). From and after the Effective Time, Acquiror shall,
and Acquiror shall cause the Acquiror Subsidiaries to, waive any pre-existing
condition limitations and credit any flexible spending account balances,
deductibles and out-of-pocket expenses to the same extent applicable and/or
covered under the Company Employee Plans, and are incurred by the employees and
their beneficiaries during the portion of the plan year prior to participation
in the benefit plans provided by Acquiror and the Acquiror Subsidiaries. The
provisions of this Section 7.4 shall not create in any employee or former
employee of the Company or any Company Subsidiary any rights to employment or
continued employment with Acquiror or the Company or any of their respective
Subsidiaries, successors or Affiliates. The provisions of this Section 7.4 shall
apply to employees and the Company who are on disability or leave of absence.

         Participants in the Company's 401(k) plan and non-qualified retirement
plans will receive all Company contributions for the partial year ending on the
Effective Time without regard to any last day of the plan year requirement or
service requirement.

         ARTICLE 7.5. SEVERANCE PLAN. For one (1) year from the Effective Time,
Acquiror shall provide employees of the Company and the Company's subsidiaries
with a Severance Plan that is no less favorable than the Company's plan
currently in effect. Acquiror shall recognize (or cause to be recognized)
service with the Company and its Subsidiaries or any predecessor entities (and
any other services credited by the Company under similar severance plans) for
all purposes under such severance plan; provided, however, that solely to the
extent necessary to avoid duplication of benefits, amounts payable under other
severance plans provided by Acquiror or an Acquiror Subsidiary may be reduced by
the amounts payable under the Company's Severance Plan.

         ARTICLE 7.6. CHANGE IN CONTROL. With respect to the Executive
Employment Agreements, the Severance Agreements and the Plans listed on Schedule
7.6(a) of the Company Disclosure Schedule (the "CHANGE IN CONTROL PLANS"), (a)
the consummation of the Merger will constitute a Change in Control as of the
Effective Time for purposes of each Change in Control Plan and (b) any
termination of employment at or following the Effective Time of or by any
individual listed on Schedule 7.6(b) of the Company Disclosure Schedule shall be
deemed to be for "Good Reason" for purposes of any Change in Control Plan in
which such individual participates or to which he or she is a party.

         ARTICLE 7.7. HEALTH INSURANCE. Acquiror will permit the individuals
listed in Schedule 7.7 of the Company Disclosure Schedule and their dependents
to receive benefits under the Acquiror's healthcare plans until such individual
reaches age 65 or is employed by another employer offering health care coverage
(including coverage of then pre-existing conditions), for the same net cost to
such individual as he or she was paying while employed by the Company (subject
to adjustment based on changes in the consumer price index).

<PAGE>   48
         ARTICLE 7.8.  THIRD PARTY BENEFICIARIES.

         (a) From and after the Effective Time, Acquiror will, and will cause
the Surviving Corporation to, honor, pay and perform all obligations under each
Change in Control Plan (including each employment, bonus, severance, termination
or similar agreement or arrangement with any current or former officer or other
employee of Company or any Company Subsidiary) in accordance with this Agreement
and the terms thereof in effect as of the date hereof (or, with the written
approval of Acquiror, as the same may be amended from time to time after the
date hereof). The obligations of Acquiror under Sections 7.3, 7.6, 7.7 and 7.8,
shall not be terminated, amended, repealed, revoked or modified in any manner
which will adversely affect any director or officer to whom such Section applies
without the consent of the affected director or officer (it being expressly
agreed that each director and officer to whom such Sections apply shall be
third-party beneficiaries of such Sections).

         (b) If Acquiror or any of its successors or assigns (i) consolidates
with or merges into any other person and shall not be the continuing or
surviving corporation or entity in a consolidation or merger or (ii) transfers
all or substantially all of its properties and assets to any Person, then, and
in each case, proper provision shall be made so that the successors and assigns
of Acquiror honor the obligations set forth in Sections 7.3, 7.6, 7.7 and 7.8.

         ARTICLE 7.9. STOCK EXCHANGE LISTING. Acquiror shall cause the Acquiror
Shares to be issued in connection with the Merger to be listed on the NASDAQ
National Market, subject to official notice of issuance.

         ARTICLE 7.10. TRANSFER TAXES. All state, local or foreign sales, use,
real property transfer, stock transfer or similar taxes (including any interest
or penalties with respect thereto) attributable to the Merger (collectively, the
"TRANSFER TAXES") shall be timely paid by Acquiror.

         ARTICLE 7.11. INVESTMENT BANKING FEE. Pursuant to the agreement
referenced in Section 4.18(a), promptly following the Effective Time, Acquiror
shall pay or cause to be paid all fees and expenses due to Goldman, Sachs & Co.
from the Company.

         ARTICLE 7.12. QUI TAM/FALSE CLAIMS ACT LITIGATION. Acquiror
acknowledges that the Company has agreed in principle with the U.S. Department
of Justice to settle the Qui Tam/False Claims Act Litigation with a payment by
the Company of $77.5 million plus relator's attorneys' fees, subject to
execution of a settlement agreement acceptable to the Company and DOJ and a
corporate integrity agreement acceptable to the Company and the Office of
Inspector General of the Department of Health and Human Services (collectively,
the "SETTLEMENT DOCUMENTS").

         Acquiror agrees to participate in good faith with the Company in
negotiating the Settlement Documents and executing such agreements as soon as
possible after the date hereof. The Company agrees to permit the Acquiror to
participate in such discussions. Acquiror further agrees to continue such good
faith negotiations if, as of the Effective Time, the Settlement Documents have
not been signed.

         ARTICLE 7.13. ACQUIROR STANDSTILL. If this Agreement is terminated,
then, for two (2) years after the date of termination, Acquiror and each of its
successors or assigns will not, and will cause its Affiliates not to:


                                       43
<PAGE>   49

                  (i) acquire, offer or propose or otherwise seek to acquire, or
         agree to acquire, directly or indirectly, by merger, purchase or
         otherwise, beneficial ownership of any assets or in excess of 1% of any
         class of securities of the Company or its Affiliates or any direct
         rights or options to acquire (through purchase, exchange, conversion or
         otherwise) any assets or in excess of 1% of any class of securities of
         the Company or its Affiliates;

                  (ii) make, or in any way participate in, directly or
         indirectly, any "solicitation" of "proxies" (as such terms are defined
         in Rule 14a-1 of Regulation 14A promulgated by the SEC as of the date
         hereof, disregarding clause (iv) of Rule 14a-1(1)(2), but including any
         solicitation exempted pursuant to Rule 14a-2(b)(1) to vote (including
         by the execution of actions by written consent), or seek to advise,
         encourage or influence any person or entity with respect to the voting
         of, any voting securities of the Company;

                  (iii) call, or in any way participate in a call for, any
         meeting of Stockholders of the Company (or take any action with respect
         to Stockholders acting by written consent);

                  (iv) form, join or in any way participate in a "group" (within
         the meaning of Section 13(d)(3) of the Exchange Act) with respect to
         any voting securities of the Company; or

                  (v) otherwise act to control or influence, or seek to control
         or influence, the Company or the management, Board of Directors,
         policies or affairs of the Company, including, (A) making any offer or
         proposal to acquire any securities or assets of the Company or any of
         its Affiliates or soliciting or proposing to effect or negotiate any
         form of business combination, restructuring, recapitalization or other
         extraordinary transaction involving the Company, its Affiliates or any
         of their respective securities or assets, (B) seeking board
         representation or the removal of any directors or a change in the
         composition or size of the Board of Directors of the Company, (C)
         making any request to amend or waive any provision of this Section
         7.13, (D) disclosing any intent, purpose, plan or proposal with respect
         to matters covered by this Section 7.13 with respect to the Company,
         its Affiliates or the boards of directors, management, policies or
         affairs or securities or assets of the Company or its Affiliates that
         is inconsistent with this Section 7.13, including an intent, purpose,
         plan or proposal that is conditioned on, or would require, waiver,
         amendment, nullification or invalidation of any provision of this
         Section 7.13, or take any action that could require the Company or any
         of its Affiliates to make any public disclosure relating to any such
         intent, purpose, plan, proposal or condition, or (E) assisting,
         advising or encouraging any person with respect to, or seeking to do,
         any of the foregoing.

         ARTICLE 7.14. PREPARATION OF RULING REQUEST. Acquiror shall be
responsible for preparing a ruling request for submission by Acquiror to the
Internal Revenue Service (the "RULING REQUEST") requesting rulings to the effect
that the transactions contemplated hereunder and related transactions will not
cause section 355(e) of the Code to apply to the spin-off of Acquiror or
LifePoint Hospitals, Inc. by Columbia/HCA Healthcare Corporation and will not
adversely affect the tax treatment of the internal restructuring transactions
that preceded such spin-off or any portion thereof. Prior to submitting the
Ruling Request or any supplement thereto to the Internal Revenue Service,
Acquiror shall deliver to the Company a draft of such item for review and
comment, and the Company shall provide its comments to Acquiror within


                                       44
<PAGE>   50

three (3) Business Days of the Company's receipt of such draft. Acquiror shall
in good faith consider any changes, modifications, additions or deletions
suggested by the Company. Acquiror shall furnish the Company with copies of all
correspondence and an oral description of all oral communications with the
Internal Revenue Service by or to Acquiror relating to the Ruling Request or the
subject matter thereof. Notwithstanding the foregoing, Acquiror shall not be
obligated to provide to the Company any information that Acquiror determines is
confidential information with respect to HCA-The Healthcare Company or LifePoint
Hospitals, Inc. The Company shall not take any action reasonably likely to
negatively affect the receipt by Acquiror or HCA-The Healthcare Company of the
Internal Revenue Service rulings described in Section 9.1(f).

         ARTICLE 7.15. Alternative Financing. If Merrill Lynch Capital
Corporation ("MLCC") terminates the Commitment Letters or indicates to Acquiror
that any condition to MLCC's obligation to provide the financing contemplated by
the Commitment Letters is not likely to be satisfied or if for any other reason
the funding contemplated by the Commitment Letters is reasonably likely to be
unavailable at Closing, Acquiror will promptly notify the Company of such fact
and will use its reasonable best efforts to obtain funding from another source
or sources to consummate the transactions contemplated by this Agreement. From
the date hereof until the Effective Time, Acquiror shall advise the Company of
any termination and of any material amendment or modification of the Commitment
Letters or any substitute therefor, including providing copies thereof to the
Company, and will provide the Company with copies of all agreements and
documents relevant to the Company's obligations under Section 6.6.

                                    ARTICLE 8

                      COVENANTS OF ACQUIROR AND THE COMPANY

         The parties hereto agree as set forth below.

         ARTICLE 8.1. REASONABLE BEST EFFORTS.

         (a) Subject to the terms and conditions hereof, each party will use
reasonable best efforts to take, or cause to be taken, all actions, to file, or
caused to be filed, all documents and to do, or cause to be done, all things
necessary, proper or advisable under applicable laws and regulations to
consummate and make effective the transactions contemplated by this Agreement as
promptly as practicable. Acquiror and the Company shall have the right to review
in advance, and to the extent reasonably practicable each will consult the other
on, all the information relating to the other and its Subsidiaries, that appear
in any filing made with, or written materials submitted to, any third party or
any Governmental Entity in connection with the Merger; provided, however, that
with respect to documents that one party reasonably believes should not be
disclosed to the other party, such party shall instead furnish those documents
to counsel for the other party pursuant to a mutually satisfactory
confidentiality agreement. In exercising the foregoing right, each of the
Company and Acquiror shall act reasonably and as promptly as reasonably
practicable.

         (b) Acquiror and the Company shall promptly respond to any request for
additional information pursuant to the HSR Act. Upon the terms and subject to
the provisions hereof,


                                       45
<PAGE>   51

Acquiror and the Company shall each use their reasonable best efforts to resolve
objections, if any, as may be asserted by any Governmental Entity with respect
to the Merger under any antitrust or trade or regulatory laws or regulations of
any Governmental Entity, which, in the case of Acquiror, will include if
necessary to resolve such objections, offering, and agreeing to enter into any
necessary agreements, including agreements to sell, license or otherwise dispose
of, or hold separate or otherwise divest itself of, all or any portion of
Acquiror's businesses or assets or any portion of the businesses or assets of
any of its Subsidiaries or any portion of the businesses or assets of the
Company or the Company's Subsidiaries. Acquiror shall reasonably consult with
the Company with regard to matters covered in this Section 8.1.

         ARTICLE 8.2. CERTAIN FILINGS; COOPERATION IN RECEIPT OF CONSENTS.

         (a) Promptly after the date hereof, Acquiror and the Company shall
prepare and Acquiror shall file with the SEC the Registration Statement, in
which the Proxy Statement/Prospectus will be included as Acquiror's prospectus.
Each of the Company and Acquiror shall use reasonable best efforts to have the
Registration Statement declared effective under the Securities Act as promptly
as practicable after the filing and to keep the Registration Statement effective
as long as is necessary to consummate the Merger. Each of the Company and
Acquiror shall mail the Proxy Statement/Prospectus to their respective
Stockholders as promptly as practicable after the Registration Statement is
declared effective under the Securities Act and, if necessary, after the Proxy
Statement/Prospectus shall have been so mailed, promptly circulate amended,
supplemental or supplemented proxy material, and, if required in connection
therewith, resolicit proxies. Acquiror shall also take any action required to be
taken under any applicable state securities or blue sky laws in connection with
the issuance of Acquiror Shares in the Merger.

         (b) No amendment or supplement to the Proxy Statement/Prospectus will
be made by the Company or Acquiror without the approval of the other party,
which approval will not be unreasonably withheld or delayed. Each party will
advise the other party, promptly after it receives notice thereof, of the time
when the Registration Statement has become effective or any supplement or
amendment has been filed, the issuance of any stop order, the suspension of the
qualification of the Acquiror Shares issuable in connection with the Merger for
offering or sale in any jurisdiction, or any request by the SEC for amendment of
the Proxy Statement/Prospectus or comments thereon and responses thereto or
requests by the SEC for additional information. If at any time prior to the
Effective Time, the Company or Acquiror discovers any information relating to
either party, or any of their respective Affiliates, officers or directors, that
should be set forth in an amendment or supplement to the Proxy
Statement/Prospectus, so that the document will not include any misstatement of
a material fact or omit to state any material fact necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading, the party that discovers any misleading information shall
promptly notify the other parties hereto and an appropriate amendment or
supplement describing the information shall be promptly filed with the SEC and,
to the extent required by law or regulation, disseminated to the Stockholders of
the Company and Acquiror.

         (c) The Company and Acquiror shall cooperate with one another in (i)
determining whether any other action by or in respect of, or filing with, any
Governmental Entity is required, or any actions, consents, approvals or waivers
are required to be obtained from parties to any material contracts, in
connection with the Merger, (ii) seeking any consents, approvals or waivers,
taking any actions, or making any filings, furnishing information required in
connection


                                       46
<PAGE>   52

therewith and seeking promptly to obtain any consents, approvals or waivers and
(iii) setting a mutually acceptable date, as close to the anticipated Closing
Date as is reasonably practicable, for the Company Stockholder Meeting and the
Acquiror Stockholder Meeting, if any, so as to enable them to occur, to the
extent practicable, on the same date. Each party shall permit the other party to
review any communication given by it to, and consult with each other in advance
of any meeting or conference with, any Governmental Entity or, in connection
with any proceeding by a private party, with any other Person, and to the extent
permitted by the applicable Governmental Entity or other Person, give the other
party the opportunity to attend and participate in the meetings and conferences,
in each case in connection with the transactions contemplated hereby.

         ARTICLE 8.3. PUBLIC ANNOUNCEMENTS. The parties shall consult with each
other before issuing any press release or making any public statement with
respect to this Agreement and the transactions contemplated hereby and, except
as may be required by applicable law or any listing agreement with any national
securities exchange, will not issue any such press release or make any public
statement prior to such consultation.

         ARTICLE 8.4. ACCESS TO INFORMATION; NOTIFICATION OF CERTAIN MATTERS.
From the date hereof until the Effective Time and subject to applicable law, the
Company and Acquiror shall (i) give to the other party, its counsel, financial
advisors, auditors and other authorized representatives reasonable access to its
personnel, offices, properties, books and records, (ii) furnish or make
available to the other party (and to any third party who has entered into a
confidentiality agreement with Acquiror, which agreement acknowledges that the
Company is a beneficiary thereunder and a copy is delivered to each party
hereto), its counsel, financial advisors, auditors and other authorized
representatives any financial and operating data and other information as those
Persons may reasonably request and (iii) instruct its employees, counsel,
financial advisors, auditors and other authorized representatives to cooperate
with the reasonable requests of the other party in its investigation. Any
investigation pursuant to this Section shall be conducted in a manner, which
will not interfere unreasonably with the conduct of the business of the other
party. Unless otherwise required by law, each of the Company and Acquiror will
hold, and will cause its respective officers, employees, counsel, financial
advisors, auditors and other authorized representatives to hold, any nonpublic
information obtained in any investigation in confidence in accordance with
Section 8.6.

         ARTICLE 8.5. FURTHER ASSURANCES. At and after the Effective Time, the
officers and directors of the Surviving Corporation will be authorized to
execute and deliver, in the name and on behalf of the Company, any deeds, bills
of sale, assignments or assurances and to take and do, in the name and on behalf
of the Company, any other actions and things to vest, perfect or confirm of
record or otherwise in the Surviving Corporation any and all right, title and
interest in, to and under any of the rights, properties or assets of the Company
acquired or to be acquired by the Surviving Corporation as a result of, or in
connection with, the Merger.

         ARTICLE 8.6. CONFIDENTIALITY. Subject to Schedule 8.6, prior to the
Effective Time and after any termination of this Agreement, each party hereto
will hold, and will use its reasonable best efforts to cause its officers,
directors, employees, accountants, counsel, consultants, advisors and agents to
hold, in confidence, unless compelled to disclose by judicial or administrative
process or by other requirements of law, all confidential documents and
information concerning


                                       47
<PAGE>   53

the other parties hereto furnished to the party in connection with the
transactions contemplated by this Agreement, except to the extent that the
information can be shown to have been (a) previously known on a nonconfidential
basis by the party, (b) in the public domain through no fault of the party or
(c) later lawfully acquired by such party from sources other than any of the
other parties hereto which sources are not known to be subject to any
confidentiality obligations; provided that a party may disclose information to
its officers, directors, employees, accountants, counsel, consultants, advisors
and agents in connection with the transactions contemplated by this Agreement,
so long as those Persons are informed by the party of the confidential nature of
information and are directed by the party to treat such information
confidentially. Each party's obligation to hold any information in confidence
shall be satisfied, if it exercises the same care with respect to the
information as it would take to preserve the confidentiality of its own similar
information. If this Agreement is terminated, each party hereto will, and will
use its reasonable best efforts to cause its officers, directors, employees,
accountants, counsel, consultants, advisors and agents to, destroy or deliver to
the party from whom the material was obtained, upon request, all documents and
other materials, and all copies thereof, obtained from the other party from the
other parties in connection with this Agreement that are subject to this
confidentiality requirement.

         ARTICLE 8.7. TAX TREATMENT. Prior to the Effective Time, each party
shall use its reasonable best efforts to cause the Merger to qualify as a 368
Reorganization, and will not take any action reasonably likely to cause the
Merger not so to qualify. Acquiror shall not take, or cause the Surviving
Corporation to take, any action after the Effective Time reasonably likely to
cause the Merger not to qualify as a 368 Reorganization.

                                    ARTICLE 9

         best efforts to resist, resolve or lift, as applicable, the law,
         regulation, judgment, injunction, order or decree;

agreement on the part of Acquiror set forth in this Agreement shall have
occurred which would cause the condition set forth in Section 9.2(a) not to be
satisfied, and such condition shall be incapable of being satisfied by the End
Date.

         (d) by Acquiror, (i) if the Company's Board of Directors shall have (A)
amended, modified, withdrawn, conditioned or qualified the Company
Recommendation in a manner adverse to Acquiror and/or (B) recommended any
Acquisition Proposal to the Company's Stockholders or entered into an
acquisition agreement with respect to a Superior Proposal; or (ii) if a breach
of or failure to perform any representation, warranty, covenant or agreement on
the part of the Company set forth in this Agreement shall have occurred which
would cause the condition set forth in Section 9.3(a) not to be satisfied, and
the condition is incapable of being satisfied by the End Date.

that the Company's Board of Directors determines to be a Superior Proposal and
(ii) the Company's Board of Directors determines in good faith, after
consultation with its outside counsel and its financial advisors, that it is
legally required for the discharge of its fiduciary duties to accept such
Superior Proposal and enter into a binding agreement concerning such Superior
Proposal; provided, however, that the Company shall not be permitted to
terminate this Agreement pursuant to this Section 10.1(e) unless it has provided
Acquiror with at least three (3) Business Days' notice of its intention to so
terminate this Agreement, specifying the material terms and conditions of the
Acquisition Proposal and the identity of the Person making the Acquisition
Proposal; provided, further, that Acquiror shall receive the fee set forth in

to provide, or obtaining, the financing for the transactions contemplated hereby
(including any fees payable to the entities providing such financing and their
respective counsel).

         (b) If this Agreement shall be terminated pursuant to (i) Section
10.1(b)(iv) and (x) at any time after the date hereof and prior to the Company

definitive agreement with respect to, or consummates, a transaction similar to
the transactions contemplated by an Acquisition Proposal with any third party or

in this Section 10.3 are an integral part of the transactions contemplated in

respectively, would not enter into this Agreement; accordingly, if the Company
or Acquiror fail to promptly pay any amount due pursuant to this Section 10.3,

which results in a judgment against the other party for a fee set forth in this

or otherwise transfer any of its rights or obligations under this Agreement
without the consent of the other parties hereto, except that Acquiror may
transfer or assign to any wholly owned Acquiror Subsidiary the right to enter
into the transactions contemplated by this Agreement; provided that no
assignment shall be permitted, if it would delay or impede the Merger or any of
the other transactions contemplated by this Agreement, and any transfer or
assignment will not relieve Acquiror of its obligations hereunder. Any purported
assignment in violation hereof shall be null and void.

         ARTICLE 11.5. COUNTERPARTS; EFFECTIVENESS; THIRD PARTY BENEFICIARIES.
This Agreement may be signed in any number of counterparts, each of which shall
be an original, with the same effect as if the signatures thereto and hereto
were upon the same instrument. This Agreement shall become effective when each
party hereto shall have received counterparts hereof signed by all of the other
parties hereto. Except as set forth in Sections 3.5 and 7.3, 7.6, 7.7 and 7.8,
no provision of this Agreement is intended to confer upon any Person other than
the parties hereto any rights or remedies hereunder.

this Agreement, the parties hereto agree that any suit, action or proceeding
seeking to enforce any provision of, or based on any matter arising out of or in
connection with, this Agreement or the transactions contemplated hereby shall be
brought in the United States District Court for the District of Delaware or, if
such court does not have jurisdiction over the subject matter of such proceeding
or if such jurisdiction is not available, in the Court of Chancery of the State
of Delaware, County of New Castle, and each of the parties hereby consents to
the exclusive jurisdiction of those courts (and of the appropriate appellate
courts therefrom) in any suit, action or proceeding and irrevocably waives, to
the fullest extent permitted by law, any objection which it may now or hereafter
have to the laying of the venue of any suit, action or proceeding in any of
those courts or that any suit, action or proceeding which is brought in any of
those courts has been brought in an inconvenient forum. Process in any suit,
action or proceeding may be served on any party anywhere in the world, whether
within or without the jurisdiction of any of the named courts. Without limiting
the foregoing, each party agrees that service of process on it by notice as
provided in Section 11.1 shall be deemed effective service of process.

         ARTICLE 11.8. ENFORCEMENT. The parties agree that irreparable damage
would occur in the event that any of the provisions of this Agreement were not
performed in accordance with their specific terms. It is accordingly agreed that
the parties shall be entitled to specific performance of the terms hereof, this
being in addition to any other remedy to which they are entitled at law or in
equity.

         ARTICLE 11.9. ENTIRE AGREEMENT. This Agreement (together with the
Schedules hereto) constitutes the entire agreement between the parties with
