AMENDED AND RESTATED
AGREEMENT AND PLAN OF MERGER

THIS AMENDED AND RESTATED AGREEMENT AND PLAN OF MERGER (the "Amended and
Restated Agreement"), dated as of April 14, 1997, by and among Columbia/HCA
Healthcare Corporation, a Delaware corporation ("Parent"), CVH Acquisition
Corporation, a Delaware corporation and a wholly owned subsidiary of Parent
("Sub"), and Value Health, Inc., a Delaware corporation (the "Company"):

W I T N E S S E T H:

WHEREAS, on January 15, 1997, Parent, Sub and the Company entered into an
agreement and plan of merger (the "Initial Agreement") to effect a business
combination by means of the merger of Sub with and into the Company (the
"Merger");

WHEREAS, the Initial Agreement provided for the exchange of the outstanding
shares of common stock, no par value, of the Company ("Company Common Stock")
for shares of common stock, $.01 par value, of Parent ("Parent Common Stock")
pursuant to the Merger;

WHEREAS, Parent, Sub and the Company desire to amend and restate the Initial
Agreement to, among other things, provide that the outstanding shares of
Company Common Stock be exchanged for cash rather than Parent Common Stock;

WHEREAS, the Boards of Directors of Parent, Sub and the Company have
approved the Merger as modified by the terms of this Amended and Restated
Agreement, upon the terms and subject to the conditions set forth herein;

NOW, THEREFORE, in consideration of the foregoing premises and the
representations, warranties and agreements contained herein the parties hereto
agree as follows:

ARTICLE I.

The Merger

Section 1.1. The Merger. Upon the terms and subject to the conditions
hereof, on the Effective Date (as defined in Section 1.2), Sub shall be merged
into the Company and the separate existence of Sub shall thereupon cease, and
the Company, as the corporation surviving the Merger (the "Surviving
Corporation"), shall by virtue of the Merger continue its corporate existence
under the laws of the State of Delaware.

Section 1.2. Effective Date of the Merger. The Merger shall become effective
at the date and time (the "Effective Date") when a properly executed
Certificate of Merger is duly filed with the Secretary of State of the State
of Delaware, which filing shall be made as soon as practicable following
fulfillment of the conditions set forth in Article IX hereof, or at such time
thereafter as is provided in such Certificate of Merger.

ARTICLE II.

The Surviving Corporation

Section 2.1. Certificate of Incorporation. Subject to Section 8.4(a), the
Certificate of Incorporation of Sub shall be the Certificate of Incorporation
of the Surviving Corporation after the Effective Date, and thereafter may be
amended in accordance with its terms and as provided by law and this Amended
and Restated Agreement.

Section 2.2. By-Laws. The By-laws of Sub as in effect on the Effective Date
shall be the By-laws of the Surviving Corporation, and thereafter may be
amended in accordance with its terms and as provided by law and this Amended
and Restated Agreement.

Section 2.3. Board of Directors; Officers. The directors of Sub immediately
prior to the Effective Date shall be the directors of the Surviving
Corporation, and the officers of the Company immediately prior to the
Effective Date shall be the officers of the Surviving Corporation, in each
case until their respective successors are duly elected and qualified.

Section 2.4. Effects of Merger. The Merger shall have the effects set forth
in Section 259 of the Delaware General Corporation Law (the "DGCL").

ARTICLE III.

Conversion of Shares

Section 3.1. Merger Consideration. On the Effective Date, by virtue of the
Merger and without any action on the part of any holder of any Company Common
Stock:

(a) All shares of Company Common Stock which are held by the Company or
any subsidiary of the Company, and any shares of Company Common Stock owned
by Parent, Sub or any other subsidiary of Parent, shall be canceled.

(b) Each remaining outstanding share of Company Common Stock shall be
converted into and represent the right to receive $20.50 in cash (the
"Merger Consideration") in accordance with Section 3.2.

(c) In the event of any stock dividend, stock split, reclassification,
recapitalization, combination or exchange of shares with respect to, or
rights issued in respect of, Company Common Stock after the date hereof,
the Merger Consideration shall be adjusted accordingly.

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

Section 3.2. Payment Procedures.

(a) Prior to the Effective Date, Parent shall select a Payment Agent, which
shall be Parent's Transfer Agent or such other person or persons reasonably
satisfactory to the Company, to act as Payment Agent for the Merger (the
"Payment Agent").

(b) As soon as practicable after the Effective Date (but in no event more
than five days thereafter), Parent shall instruct the Payment Agent to mail to
each holder of a certificate or certificates evidencing shares of Company
Common Stock (other than Dissenting Shares, as defined in Section 3.3)
("Certificates") (A) a letter of transmittal (which shall include a Substitute
Form W-9 and shall specify that delivery shall be effected, and risk of loss
and title to the Certificates shall pass, only upon proper delivery of such
Certificates to the Payment Agent) and (B) instructions to effect the
surrender of the Certificates in exchange for the Merger Consideration. Each
holder of Company Common Stock, upon surrender to the Payment Agent of such
holder's Certificates with the letter of transmittal, duly executed, and such
other customary documents as may be required pursuant to such instructions,
shall be paid the amount to which such holder is entitled, pursuant to this
Amended and Restated Agreement, of cash as payment of the Merger Consideration
(without any interest accrued thereon). Until so surrendered, each Certificate
shall after the Effective Date represent for all purposes only the right to
receive the Merger Consideration. In the event any Certificate shall have been
lost, stolen or destroyed, upon the making of an affidavit of that fact by the
person claiming such Certificate to be lost, stolen or destroyed and, if
required by the Surviving Corporation, the posting by such person of a bond in
such reasonable amount as the Surviving Corporation may direct as indemnity
against any claim that may be made against it with respect to

such Certificate, the Paying Agent will deliver in exchange for such lost,
stolen or destroyed Certificate the Merger Consideration payable in respect
thereof pursuant to this Amended and Restated Agreement.

(c) At the Closing of the transactions contemplated by this Amended and
Restated Agreement (the "Closing"), Parent shall deposit in trust with the
Payment Agent, for the ratable benefit of the holders of Company Common Stock,
the appropriate amount of cash to which such holders are entitled pursuant to
this Amended and Restated Agreement for payment of the Merger Consideration
(the "Payment Fund"). The Payment Agent shall, pursuant to irrevocable
instructions, make the payments to the holders of Company Common Stock as set
forth in this Amended and Restated Agreement.

(d) If any delivery of the Merger Consideration is to be made to a person
other than the registered holder of the Certificates surrendered in exchange
therefor, it shall be a condition to such delivery that the Certificate so
surrendered shall be properly endorsed or be otherwise in proper form for
transfer and that the person requesting such delivery shall (i) pay to the
Payment Agent any transfer or other taxes required as a result of delivery to
a person other than the registered holder or (ii) establish to the
satisfaction of the Payment Agent that such tax has been paid or is not
payable.

(e) Any portion of the Payment Fund that remains undistributed to the
holders of Company Common Stock as of the first anniversary of the Effective
Date shall be delivered to Parent upon demand, and any holder of Company
Common Stock who has not theretofore complied with the exchange requirements
of this Section shall have no further claim upon the Payment Agent and shall
thereafter look only to Parent for payment of the Merger Consideration.

(f) If a Certificate has not been surrendered prior to the date on which any
receipt of Merger Consideration would otherwise escheat to or become the
property of any governmental agency, such Certificate shall, to the extent
permitted by applicable law, be deemed to be canceled and no money or other
property will be due to the holder thereof.

(g) The Payment Agent may invest cash in the Payment Fund, as directed by
Parent, on a daily basis, provided that all such investments shall be in
obligations of or guaranteed by the United States of America with remaining
maturities not exceeding 180 days, in commercial paper obligations receiving
the highest rating from either ▇▇▇▇▇'▇ Investors Services, Inc. or Standard &
Poor's Corporation, or in certificates of deposit or banker's acceptances of
commercial banks with capital exceeding $500 million (collectively, "Permitted
Investments"). The maturities of Permitted Investments shall be such as to
permit the Payment Agent to make prompt payment to former stockholders of the
Company entitled thereto as contemplated by this Section. Parent shall
promptly replenish the Payment Fund to the extent of any losses incurred as a
result of Permitted Investments. Any interest and other income resulting from
such investments shall be paid to Parent. If for any reason (including losses)
the Payment Fund is inadequate to pay the amounts to which holders of Company
Common Stock shall be entitled under this Amended and Restated Agreement,
Parent shall in any event be liable for payment thereof. The Payment Fund
shall not be used for any purpose not specifically provided for in this
Amended and Restated Agreement.

Section 3.3. Dissenting Shares. (a) Notwithstanding any other provision of
this Amended and Restated Agreement to the contrary, shares of Company Common
Stock that are outstanding immediately prior to the Effective Date and which
are held by holders who shall have not voted in favor of the Merger or
consented thereto in writing and who shall have demanded properly in writing
appraisal for such shares in accordance with Section 262 of the DGCL and who
shall not have withdrawn such demand or otherwise have forfeited appraisal
rights (collectively, the "Dissenting Shares") shall not be converted into or
represent the right to receive the Merger Consideration. Such holders shall be
entitled to receive payment of the appraised value of such shares, except that
all Dissenting Shares held by holders who shall have failed to perfect or who
effectively shall have withdrawn or lost their rights to appraisal of such
shares under such Section 262 shall thereupon be deemed to have been converted
into and to have become exchangeable, as of the Effective Date, for the right
to receive, without any interest thereon, the Merger Consideration, upon
surrender of the Certificates evidencing such shares.

(b) The Company shall give Parent (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 direct all negotiations and proceedings with respect to
demands for appraisal under the DGCL. The Company shall not, except with the
prior written consent of Parent, make any payment with respect to any demands
for appraisal, or offer to settle, or settle, any such demands.

Section 3.4. [Reserved].

Section 3.5. Stock Options. (a) Each of the Company's stock option plans,
each of which is set forth in Section 3.5(a) of the Company Disclosure
Schedule (as defined in Section 5.1) (the "Option Plans"), and each option to
acquire shares of Common Stock outstanding immediately prior to the Effective
Date thereunder, whether vested or unvested (each, an "Option" and
collectively, the "Options"), shall be assumed by the Parent at the Effective
Date, and each such Option shall become an option to purchase a number of
shares of Parent Common Stock (a "Substitute Option") (rounded to the nearest
whole share, with 0.5 shares being rounded up) equal to the number of shares
of Company Common Stock subject to such Option multiplied by the Option
Exchange Ratio (as defined below). The per share exercise price for each
Substitute Option shall be the current exercise price per share of Company
Common Stock divided by the Option Exchange Ratio (rounded up to the nearest
full cent), and each Substitute Option otherwise shall after the Effective
Date be subject to all of the other terms and conditions of the original
Option to which it relates (including, without limitation, all provisions
relating to acceleration of vesting). Prior to the Effective Date, the Company
shall take such additional actions as are necessary under applicable law and
the applicable agreements and Option Plans to ensure that each outstanding
Option shall, from and after the Effective Date, represent only the right to
purchase, upon exercise, shares of Parent Common Stock. Except as set forth in
Section 3.5(a) of the Company Disclosure Schedule, the vesting of no Option
shall be accelerated by reason of the Merger unless the agreement or
arrangement under which it was granted or by which it is otherwise governed
specifically provides for such acceleration. For avoidance of doubt, it is the
intention of Parent and the Company that the Substitute Options be identical
in all respects to the Options (except for the number and type of shares for
which they shall be exercisable and the exercise price thereof) and that,
without limitation, (i) all terms of the plans under which such Options were
issued and (ii) all policies set forth in Sections 3.5 and 5.8 of the Company
Disclosure Schedule, shall apply thereto from and after the Effective Date.

(b) For purposes of this Amended and Restated Agreement, the term "Option
Exchange Ratio" shall mean the ratio of (x) $20.50 to (y) the average of the
closing prices per share of the Parent Common Stock on the New York Stock
Exchange, as reported in the Wall Street Journal, for each of the ten trading
days immediately preceding the Effective Date.

(c) As soon as practicable after the Effective Date, Parent shall cause to
be included under a registration statement on Form S-8 of Parent all shares of
Parent Common Stock which are subject to Substitute Options, and shall
maintain the effectiveness of such registration statement until all Substitute
Options have been exercised, expired or forfeited.

Section 3.6. Stockholders' Meetings. The Company shall take all action
necessary, in accordance with applicable law and its Certificate of
Incorporation and By-laws, to convene a special meeting of the holders of
Company Common Stock (the "Company Meeting") as promptly as practicable for
the purpose of considering and taking action upon this Amended and Restated
Agreement. Subject to the exercise of its good faith judgment as to its
fiduciary duties to its stockholders imposed by law, as advised by outside
counsel, the Board of Directors of the Company will recommend that holders of
Company Common Stock vote in favor of and approve the Merger and the adoption
of the Amended and Restated Agreement at the Company Meeting. At the Company
Meeting, all of the shares of Company Common Stock then owned by Parent, Sub,
or any other subsidiary of Parent, or with respect to which Parent, Sub, or
any other subsidiary of Parent holds the power to direct the voting, will be
voted in favor of approval of the Merger and adoption of this Amended and
Restated Agreement.

Section 3.7. Closing of the Company's Transfer Books. At the Effective Date,
the stock transfer books of the Company shall be closed and no transfer of
shares of Company Common Stock shall be made thereafter. In the event that,
after the Effective Date, Certificates are presented to the Surviving
Corporation, they shall be canceled and exchanged for the Merger Consideration
as provided in Sections 3.1(b) and 3.2.

Section 3.8. Assistance in Consummation of the Merger. Each of Parent, Sub
and the Company shall provide all reasonable assistance to, and shall
cooperate with, each other to bring about the consummation of the Merger as
soon as possible in accordance with the terms and conditions of this Amended
and Restated Agreement. Parent shall cause Sub to perform all of its
obligations in connection with this Amended and Restated Agreement.

Section 3.9. Closing. The Closing shall take place (i) at the offices of
▇▇▇▇▇▇▇ ▇▇▇▇ & ▇▇▇▇▇▇▇▇▇, One Citicorp Center, ▇▇▇ ▇▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇,
▇▇▇ ▇▇▇▇ ▇▇▇▇▇, at 9:00 A.M. local time on the day which is at least one
business day after the day on which the last of the conditions set forth in
Article IX (other than those that can only be fulfilled on the Effective Date)
is fulfilled or waived or (ii) at such other time and place as Parent and the
Company shall agree in writing.

Section 3.10. Transfer Taxes. Parent and Company shall cooperate in the
preparation, execution and filing of all returns, applications or other
documents regarding any real property transfer, stamp, recording, documentary
or other taxes (including, without limitation, any New York State Real Estate
Transfer Tax) and any other fees and similar taxes which become payable in
connection with the Merger other than transfer or stamp taxes payable in
respect of transfers pursuant to Section 3.2(d)(i) (collectively, "Transfer
Taxes"). From and after the Effective Date, Parent shall pay or cause to be
paid, without deduction or withholding from any amounts payable to the holders
of Company Common Stock, all Transfer Taxes.

State of Delaware and has the corporate power to carry on its business as it
is now being conducted or currently proposed to be conducted. The Company is
duly qualified as a foreign corporation to do business, and is in good
standing, in each jurisdiction where the character of its properties owned or
held under lease or the nature of its activities makes such qualification

"Securities Act")) ("Significant Subsidiary") of the Company has been named in
the Company SEC Reports (as hereinafter defined). Each Subsidiary of the
Company is a corporation duly organized, validly existing and in good standing
under the laws of its jurisdiction of incorporation (except where the failure
to be validly existing and in good standing would not be material to the
business of such Subsidiary) and has the corporate power to carry on its
business as it is now being conducted or currently proposed to be conducted.
Each Subsidiary of the Company is duly qualified as a foreign corporation to
do business, and is in good standing, in each jurisdiction where the character
of its properties owned or held under lease or the nature of its activities
makes such qualification necessary except where the failure to be so
qualified, when taken together with all such failures, has not had, or would
not reasonably be expected to have, a Company Material Adverse Effect. Section
5.3 of the Company

Disclosure Schedule contains, with respect to each Subsidiary of the Company,
its name and jurisdiction of incorporation and, with respect to each
Subsidiary that is not wholly owned, the number of issued and outstanding
shares of capital stock and the number of shares of capital stock owned by the
Company or a Subsidiary. All the outstanding shares of capital stock of each
Subsidiary of the Company are validly issued, fully paid and nonassessable,
and those owned by the Company or by a Subsidiary of the Company are owned
free and clear of any liens, claims or encumbrances. Except as set forth in
Section 5.3 of the Company Disclosure Schedule, there are no existing options,
warrants, calls or other rights, agreements or commitments of any character
relating to the issued or unissued capital stock or other securities of any of
the Subsidiaries of the Company. Except as set forth in the Company's Annual
Report on Form 10-K for the fiscal year ended December 31, 1996, or as
disclosed in Section 5.3 of the Company Disclosure Schedule and except for
wholly owned subsidiaries which are formed after the date hereof in the
ordinary course of business consistent with past practice, the Company does

partnership, joint venture or other business association or entity.

Restated Agreement and the consummation of the transactions contemplated

be limited by bankruptcy, insolvency or other similar laws affecting the
enforcement of creditors' rights generally and except that the availability of
equitable remedies, including specific performance, is subject to the

Except for the approval of the holders of a majority of the shares of Company
Common Stock, no other corporate proceedings on the part of the Company are
necessary to authorize this Amended and Restated Agreement and the
transactions contemplated hereby. Except as set forth in Section 5.4 of the
Company Disclosure Schedule, the Company is not subject to or obligated under
(i) any charter, by-law, indenture or other loan document provision or (ii)

applicable to the Company or any of its Subsidiaries or their respective
properties or assets which would be breached or violated, or under which there
would be a default (with or without notice or lapse of time, or both), or
under which there would arise a right of termination, cancellation,
modification or acceleration of any obligation or the loss of a material
benefit, by its executing and carrying out this Amended and Restated
Agreement, other than, in the case of clause (ii) only, (A) any breaches,
violations, defaults, terminations, cancellations, modifications,
accelerations or losses which, either singly or in the aggregate, have not
had, or would not reasonably be expected to have, a Company Material Adverse
Effect or prevent the consummation of the transactions contemplated hereby and
(B) the laws and regulations referred to in the next sentence. Except as
disclosed in Section 5.4 of the Company Disclosure Schedule or, with respect
to the Merger or the transactions contemplated thereby, in connection, or in
compliance, with the provisions of the HSR Act, the Securities Act, the
Exchange Act, and the corporation, securities or blue sky laws or regulations
of the various states, no filing or registration with, or authorization,
consent or approval of, any public body or authority is necessary for the
consummation by the Company of the Merger or the other transactions
contemplated hereby, other than filings, registrations, authorizations,
consents or approvals the failure of which to make or obtain has not had, or
would not reasonably be expected to have, a Company Material Adverse Effect or
prevent the consummation of the transactions contemplated hereby.

furnished Parent with true and complete copies of its (i) Annual Reports on

as to form in all material respects with the requirements of the Securities
Act or the Exchange Act, as the case may be, and the rules and regulations of
the Commission thereunder applicable to such Company SEC Reports. As of their
respective dates, the Company SEC Reports did not contain any untrue statement
of a material fact or omit to state a material fact required to be stated

circumstances under which they were made, not misleading. The audited
consolidated financial statements of the Company included in the Company SEC
Reports comply as to form in all material respects with applicable accounting

with respect thereto. The financial statements included in the Company SEC

termination pay; (x) any entry by the Company or any of its Subsidiaries into
any employment, severance, bonus or termination agreement with any director,
officer or employee of the Company or any of its Subsidiaries; or (xi) any
agreement (whether or not in writing), arrangement or understanding to do any
of the foregoing.

Section 5.7. Litigation. Except as disclosed in the Company's Annual Report
on Form 10-K for the year ended December 31, 1996 or as disclosed in Section
5.7 of the Company Disclosure Schedule, there is no suit, action or proceeding
pending or, to the knowledge of the Company, threatened against the Company or
any of its Subsidiaries which, either alone or in the aggregate, has had or
would reasonably be expected to have a Company Material Adverse Effect, nor is
there any judgment, decree, injunction, rule or order of any court,
governmental department, commission, agency, instrumentality or arbitrator
outstanding against the Company or any of its subsidiaries having, or which
would reasonably be expected to have, either alone or in the aggregate, any
such Company Material Adverse Effect.

Section 5.8. Employee Benefit Plans. (a) Section 5.8 of the Company
Disclosure Schedule hereto sets forth a list of all "employee benefit plans",
as defined in Section 3(3) of ERISA, and all other material employee benefit
arrangements or payroll practices, including, without limitation, any such
arrangements or payroll practices providing severance pay, sick leave,
vacation pay, salary continuation for disability, retirement benefits,
deferred compensation, bonus pay, incentive pay, stock options (including
those held by Directors, employees, and consultants), hospitalization
insurance, medical insurance, life insurance, scholarships or tuition
reimbursements, that are maintained by the Company, any Subsidiary of the
Company or any Company ERISA

Affiliate (as defined below) or to which the Company, any Subsidiary of the
Company or any Company ERISA Affiliate is obligated to contribute thereunder
for current or former employees, independent contractors, consultants and
leased employees of the Company, any Subsidiary of the Company or any Company
ERISA Affiliate (the "Company Employee Benefit Plans").

(b) None of the Company Employee Benefit Plans is a "multiemployer plan", as
defined in Section 4001(a)(3) of ERISA (a "Multiemployer Plan"), and neither
the Company nor any Company ERISA Affiliate presently maintains such a plan.
None of the Company, any Subsidiary or Company ERISA Affiliate (subject to the
knowledge of the Company, in the case of any Subsidiary or Company ERISA
Affiliate acquired by the Company, for periods prior to such acquisition), has
withdrawn in a complete or partial withdrawal from any Multiemployer Plan, nor
has any of them incurred any material liability due to the termination or
reorganization of such a Multiemployer Plan.

(c) No Company Benefit Plan nor the Company has incurred any material
liability or penalty under Section 4975 of the Code or Section 502(i) of
ERISA.

(d) Except as set forth in Section 5.8 of the Company Disclosure Schedule,
the Company does not maintain or contribute to any plan or arrangement which
provides or has any liability to provide life insurance or medical or other
employee welfare benefits to any employee or former employee upon his
retirement or termination of employment, and the Company has never
represented, promised or contracted (whether in oral or written form) to any
employee or former employee that such benefits would be provided.

(e) Except as set forth on Section 5.8 of the Company Disclosure Schedule,
the execution of, and performance of the transactions contemplated in, this
Amended and Restated Agreement will not, either alone or upon the occurrence
of subsequent events, result in any payment (whether of severance pay or
otherwise), acceleration, forgiveness of indebtedness, vesting, distribution,
increase in benefits or obligation to fund benefits with respect to any
employee. The only severance agreements or severance policies applicable to
the Company or its Subsidiaries in the event of a change of control of the
Company are the agreements and policies specifically referred to in Section
5.8 of the Company Disclosure Schedule (and, in the case of such agreements,
the form of which is attached to the Company Disclosure Schedule). Each
executive officer of the Company (as such term is defined in Rule 3b-7 under
the Exchange Act) and each of the individuals identified on Section 5.8(e) of
the Company Disclosure Schedule is a party to a non-competition agreement with
the Company or a Significant Subsidiary, as the case may be, and copies of the
forms of such non-competition agreements are attached to Section 5.8 of the
Company Disclosure Schedule.

(f) None of the Company Employee Benefit Plans is a "single employer plan",
as defined in Section 4001(a)(15) of ERISA, that is subject to Title IV of
ERISA, and neither the Company nor any Company ERISA Affiliate presently
maintains such a plan. None of the Company, any of its Subsidiaries or any
ERISA Affiliate has any material liability under Section 4062 of ERISA to the
Pension Benefit Guaranty Corporation or to a trustee appointed under Section
4042 of ERISA. None of the Company, any Subsidiary, or any Company ERISA
Affiliate (subject to the knowledge of the Company, in the case of any
Subsidiary or Company ERISA Affiliate acquired by the Company, for periods
prior to such acquisition) has engaged in any transaction described in Section
4069 of ERISA.

(g) Each Company Employee Benefit Plan that is intended to qualify under
Section 401 of the Code, and each trust maintained pursuant thereto, has been
determined to be exempt from federal income taxation under Section 501 of the
Code by the IRS, and, to the Company's knowledge, nothing has occurred with
respect to the operation or organization of any such Company Employee Benefit
Plan and there have been no amendments to any such Company Employee Benefit
Plan that would cause the loss of such qualification or exemption or the
imposition of any material liability, penalty or tax under ERISA or the Code.

(h) Except as set forth on Section 5.8(h) of the Company Disclosure
Schedule, all contributions (including all employer contributions and employee
salary reduction contributions) required to have been made under any

of the Company Employee Benefit Plans to any funds or trusts established
thereunder or in connection therewith have been made by the due date thereof
and no contributions have been made to the Company Employee Benefit Plans that
would be considered non-deductible under the Code.

(i) There has been no material violation of ERISA or the Code with respect
to the filing of applicable reports, documents and notices regarding the
Company Employee Benefit Plans with the Secretary of Labor or the Secretary of
the Treasury or the furnishing of required reports, documents or notices to
the participants or beneficiaries of the Company Employee Benefit Plans.

(j) True, correct and complete copies of the following documents, with
respect to each of the Company Benefit Plans, have been delivered or made
available to the Parent by the Company: (i) all plans and related trust
documents and any other instruments or contracts under which the Company
Employee Benefit Plans are operated, and amendments thereto; (ii) the Forms
5500 for the past three years and (iii) summary plan descriptions.

(k) There are no pending actions, claims or lawsuits which have been
asserted, instituted or, to the Company's knowledge, threatened, against the
Company Employee Benefit Plans, the assets of any of the trusts under such
plans or the plan sponsor or the plan administrator, or, to the Company's
knowledge, against any fiduciary of the Company Employee Benefit Plans with
respect to the operation of such plans (other than routine benefit claims).

(l) The Company Employee Benefit Plans have been maintained, in all material
respects, in accordance with their terms and with all provisions of ERISA and
the Code (including rules and regulations thereunder) and other applicable
federal and state laws and regulations.

For purposes of this Amended and Restated Agreement, "Company ERISA
Affiliate" means any business or entity which is a member of the same
"controlled group of corporations," under "common control" or an "affiliated
service group" with an entity within the meanings of Sections 414(b), (c) or
(m) of the Code, or required to be aggregated with the entity under Section
414(o) of the Code, or is under "common control" with the entity, within the

to the knowledge of the executive officers of the Company, threatened against
the Company or its Subsidiaries relating to their business, except for any
such proceeding which has not had, or would not reasonably be expected to
have, a Company Material Adverse Effect. To the best knowledge of the Company,
there are no organizational efforts with respect to the formation of a
collective bargaining unit presently being made or threatened involving
employees of the Company or any of its Subsidiaries. There is no labor strike,
material slowdown or material work stoppage or lockout actually pending or, to

Section 5.12. Compliance with Applicable Laws. The Company and each of its
Subsidiaries hold all permits, licenses, variances, exemptions, orders and
approvals of all courts, administrative agencies or commissions or other
governmental authorities or instrumentalities, domestic or foreign (each, a
"Governmental Entity"), material to the business of the Company or such
Subsidiary, as the case may be, including, without limitation, applicable
state insurance and health commissions, and other Governmental Entities
regulating exclusive provider organizations, preferred provider organizations,
medical utilization review organizations or third-party administrators (the
"Company Permits"). The Company and its Subsidiaries are in compliance in all
material respects with the terms of the Company Permits, except for such
failures to comply which, singly or in the aggregate, would not be material to
the business of the Company or such Subsidiary, as the case may be. Except as
disclosed in the Company SEC Reports filed prior to the date of this Amended
and Restated Agreement or in Section 5.12 of the Company Disclosure Schedule,
the Company and each of its Subsidiaries are in compliance in all material

between Parent and the Company.

Section 8.2. Proxy Statement. Parent and the Company shall cooperate and
promptly prepare, and the Company shall file with the Commission as soon as

the Parent or its affiliates is made available to the employees of the
Surviving Corporation or its Subsidiaries: (i) service with the Company and
the Subsidiaries by any employee prior to the Effective Date shall be credited
for eligibility and vesting purposes under such plan, program or policy, but
not for benefit accrual purposes, and (ii) with respect to any welfare benefit
plans to which such employees may become eligible, Parent shall cause such
plans to provide credit for any co-payments or deductibles by such employees

welfare plans maintained by the Company and the Subsidiaries for their
employees prior to the Effective Date.

Section 8.4. Indemnification. (a) From and after the Effective Date, Parent
shall indemnify, defend and hold harmless the officers, directors and
employees of the Company and its subsidiaries who were such at any time prior

expenses, claims, damages or liabilities arising out of the transactions
contemplated by this Amended and Restated Agreement to the fullest extent
permitted or required under applicable law, including without limitation the
advancement of expenses. Parent agrees that all rights to indemnification
existing in favor of the directors, officers or employees of the Company as
provided in the Company's Certificate of Incorporation or By-Laws, as in
effect as of the date hereof, with respect to matters occurring through the
Effective Date, shall survive the Merger and shall continue in full force and
effect for a period of not less than six years from the Effective Date. Parent
agrees to cause the Surviving Corporation to maintain in effect for not less
than three years after the Effective Date the current policies of directors'
and officers' liability insurance maintained by the Company with respect to
matters occurring on or prior to the Effective Date; provided, however, that
the Surviving Corporation may substitute therefor policies of at least the
same coverage (with carriers comparable to the Company's existing carriers)
containing terms and conditions which are no less advantageous to the
Indemnified Parties; and provided, further, that Parent shall not be required
in order to maintain or procure such coverage to pay an annual premium in
excess of 200% of the current annual premium paid by the Company for its
existing coverage (the "Cap"); and provided, further, that if equivalent
coverage cannot be obtained, or can be obtained only by paying an annual
premium in excess of the Cap, Parent shall only be required to obtain as much
coverage as can be obtained by paying an annual premium equal to the Cap.

(b) In the event that any action, suit, proceeding or investigation relating
hereto or to the transactions contemplated by this Amended and Restated
Agreement is commenced, whether before or after the Effective

Date, the parties hereto agree to cooperate and use their respective
reasonable efforts to vigorously defend against and respond thereto.

contemplated hereby, and to respond as promptly as practicable to any
inquiries received from the Federal Trade Commission (the "FTC") and the
Antitrust Division of the Department of Justice (the "Antitrust Division") for
additional information or documentation and to respond as promptly as
practicable to all inquiries and requests received from any State Attorney
General or other governmental authority in connection with antitrust matters.

Section 8.6. Additional Agreements. (a) Subject to the terms and conditions
herein provided, each of the parties hereto agrees to use all reasonable
efforts to take, or cause to be taken, all actions 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 Amended and Restated Agreement, including using all reasonable efforts to
obtain all necessary waivers, consents and approvals, to effect all necessary
registrations and filings (including, but not limited to, filings under the
HSR Act and with all applicable Governmental Entities) and to lift any
injunction to the Merger (and, in such case, to proceed with the Merger as
expeditiously as possible).

(b) In case at any time after the Effective Date any further action is
necessary or desirable to carry out the purposes of this Amended and Restated
Agreement, the proper officers and/or directors of Parent, the Company and the
Surviving Corporation shall take all such necessary action.

Section 8.7. Alternative Proposals. Prior to the Effective Date, the Company
agrees (a) that neither it nor any of its Subsidiaries shall, and it shall
direct and use its best efforts to cause its officers, directors, employees,
agents and representatives (including, without limitation, any investment
banker, attorney or accountant retained by it or any of its Subsidiaries) not
to, initiate, solicit or encourage, directly or indirectly, any inquiries or
the making or implementation of any proposal or offer (including, without
limitation, any proposal or offer to its stockholders) with respect to a
merger, acquisition, consolidation or similar transaction involving, or any
purchase of all or any significant portion of the assets or any equity
securities of, the Company or any of its Significant Subsidiaries (any such
proposal or offer being hereinafter referred to as an "Alternative Proposal")
or engage in any negotiations concerning, or provide any confidential
information or data to, or have any discussions with, any person relating to
an Alternative Proposal, or release any third party from any obligations under
any existing standstill agreement or arrangement relating to any Alternative
Proposal, or otherwise facilitate any effort or attempt to make or implement
an Alternative Proposal; (b) 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 of the foregoing, and it will
take the necessary steps to inform the individuals or entities referred to
above of the obligations undertaken in this Section 8.7; and (c) that it will
notify Parent immediately if any such inquiries or proposals are received by,
any such information is requested from, or any such negotiations or
discussions are sought to be initiated or continued with, it; provided,
however, that nothing contained in this Section 8.7 shall prohibit the Board
of Directors of the Company from (i) furnishing information to or entering
into discussions or negotiations with, any person or entity that makes an
unsolicited bona fide proposal to acquire the Company pursuant to a merger,
consolidation, share exchange, purchase of a substantial portion of assets,
business combination or other similar transaction, if, and only to the extent
that, (A) the Board of Directors of the Company determines in good faith that
such action is required for the Board of Directors to comply with its
fiduciary duties to stockholders imposed by law, (B) prior to furnishing such
information to, or entering into discussions or negotiations with, such person
or entity, the Company provides written notice to Parent to the effect that it
is furnishing information to, or entering into discussions or negotiations
with, such person or entity and (C) the Company keeps Parent promptly informed
of the status and all material terms and conditions of any such discussions or
negotiations (including identities of parties) and, if any such proposal or
inquiry is in writing, furnishes a copy of such proposal or inquiry to Parent
as soon as practicable after the receipt thereof; and (ii) to the extent
applicable, complying with Rule 14e-2 promulgated

under the Exchange Act with regard to an Alternative Proposal. Nothing in this
Section 8.7 shall (x) permit the Company to terminate this Amended and
Restated Agreement (except as specifically provided in Article X hereof), (y)
permit the Company to enter into any agreement with respect to an Alternative
Proposal during the term of this Amended and Restated Agreement (it being
agreed that during the term of this Amended and Restated Agreement, the
Company shall not enter into any agreement with any person that provides for,
or in any way facilitates, an Alternative Proposal (other than a
confidentiality agreement in customary form)), or (z) affect any other
obligation of the Company under this Amended and Restated Agreement.

Section 8.8. Advice of Changes; SEC Filings. The Company shall confer on a
regular basis with Parent on operational matters. Parent and the Company shall
promptly advise each other orally and in writing of any change or event that
has had, or could reasonably be expected to have, a Company Material Adverse
Effect or a Parent Material Adverse Effect, as the case may be. The Company
and Parent shall promptly provide each other (or their respective counsel)
copies of all filings made by such party with the Commission or any other
state or federal Governmental Entity in connection with this Amended and
Restated Agreement and the transactions contemplated hereby.

Section 8.9. Restructuring of Merger. Upon the mutual agreement of Parent
and the Company, the Merger shall be restructured in the form of a forward
subsidiary merger of the Company into Sub, with Sub being the surviving
corporation, or as a merger of the Company into Parent, with Parent being the
surviving corporation. In such event, this Amended and Restated Agreement
shall be deemed appropriately modified to reflect such form of merger.

representations and warranties (including the Company Disclosure Schedule to
the extent it relates thereto) in this Amended and Restated Agreement, insofar
as they relate to its Subsidiaries, are made as though Value Oncology

taking such action of compliance with any representations, warranties,
covenants or agreements contained in this Amended and Restated Agreement. The
waiver by any party hereto of a breach of any provision hereunder shall not
operate or be construed as a waiver of any prior or subsequent breach of the
same or any other provision hereunder.

the Parent Disclosure Schedule and all Exhibits attached hereto and referred
to herein are hereby incorporated herein and made a part hereof for all

affecting the validity or enforceability of any of the terms or provisions

of this Amended and Restated Agreement in any other jurisdiction. If any
