Item 5.  Other Events.

         On March 27, 1995,  Diagnostek,  Inc. (the "Registrant") entered into a
definitive Agreement and Plan of Merger, dated as of March 27, 1995, among Value
Health,  Inc. ("VHI"),  VHI Merger-Sub. Corp., a wholly-owned  subsidiary of VHI
("VHI Sub"), and the Registrant (the "Merger Agreement"),  pursuant to which VHI
Sub will merge (the "Merger") with and into the Registrant,  with the Registrant
being the surviving  corporation  in the Merger.  It is intended that the Merger
will qualify as a "pooling of interests"  for  accounting  purposes and that the
Merger  will  constitute  a  tax-free  reorganization  for  federal  income  tax
purposes.

         Pursuant to the terms and  conditions of the Merger  Agreement,  at the
effective  time of the Merger,  each share of common  stock,  par value $.01 per
share, of the Registrant (the "Registrant  Common Stock") will be converted into
the right to receive .55 shares (the "Exchange  Ratio") of the common stock,  no
par value, of VHI.

     Consummation   of  the  Merger  is  subject  to   satisfaction  of  certain
conditions,  including  approval by the Registrant's  stockholders of the Merger
Agreement,  receipt  of  regulatory  approvals,  treatment  of the  Merger  as a
"pooling of interest" for  accounting  purposes and the accuracy of each party's
representations  and warranties as of the effective  time of the Merger.  In the
event of termination under specified conditions,  VHI may be entitled to receive
a fee of $15 million  from the  Registrant.  A copy of the Merger  Agreement  is
attached as Exhibit 10.1 and is hereby incorporated by reference.

     In  connection  with  the  Merger  Agreement,   Nunzio  P.  DeSantis,   the
Registrant's Chairman of the Board and Chief Executive Officer, has entered into
a five year  Consulting  Agreement and a ten year  Agreement Not to Compete with
VHI and the Registrant,  effective only upon the  consummation of the Merger.  A
copy of each of the  Consulting  Agreement  and  Agreement  Not to  Compete  are
attached as Exhibits 10.2 and 10.3, respectively, and are hereby incorporated by
reference.

         A copy of the joint  press  release of the  Registrant  and VHI,  dated
March 27,  1995,  is  attached  as Exhibit  10.4 and is hereby  incorporated  by
reference.

     As a result of the announcement of the execution of the Merger Agreement, a
number of  shareholder  suits  have been filed in the Court of  Chancery  in the
State of Delaware against the Registrant,  its directors and VHI seeking,  among
other things,  to enjoin the Merger and compel the  directors to reconsider  the
Exchange Ratio.

                          THE SURVIVING CORPORATION

     Section 2. l Certificate of Incorporation. The Certificate of Incorporation

Date shall be the Bylaws of the Surviving Corporation.

     Section 2.3 Board of Directors,  Officers. The directors of Sub immediately

and the officers of the Company immediately prior to the Effective Date shall be

                                  ARTICLE III
                             CONVERSION OF SHARES

     Section 3.1 Exchange  Ratio. On the Effective Date, by virtue of the Merger
and without any action on the part of any holder of any common stock,  $0.01 par
value, of the Company ("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)  Subject to  Section  3.4,  each  remaining  outstanding  share of
Company  Common  Stock  shall be  converted  into the right to receive  .55 (the
"Exchange Ratio") fully paid and nonassessable shares of the no par value common
stock of Parent ("Parent Common Stock").

          (c) In the event of any stock dividend, stock split, reclassification,

<PAGE>



     Section 3.2 Parent to Make Certificates Available.

          (a)  Prior to the  Closing,  Parent  shall  select  Mellon  Securities
Transfer Services or such other person or persons reasonably satisfactory to the
Company to act as Exchange Agent for the Merger (the "Exchange Agent").  As soon
as practicable after the Effective Date,  Parent shall make available,  and each
holder of Company  Common Stock will be entitled to receive,  upon  surrender to
the Exchange  Agent of one or more  certificates  ("Certificates")  representing
such stock for cancellation,  certificates  representing the number of shares of
Parent  Common Stock into which such shares are converted in the Merger and cash
in consideration of fractional  shares as provided in Section 3.4. Parent Common
Stock into which Company  Common Stock shall be converted in the Merger shall be
deemed to have been issued on the Effective Date (the "Share Consideration").

          (b) Any holder of shares of Company Common Stock who has not exchanged
his shares for Parent Common Stock in accordance  with subsection (a) within six
months after the  Effective  Time shall have no further  claim upon the Exchange
Agent and shall thereafter look only to Parent and the Surviving Corporation for
payment in respect of his shares of Company Common Stock.  Until so surrendered,
certificates  representing Company Common Stock shall represent solely the right
to receive the Share  Consideration  (and cash in lieu of any fractional  shares
pursuant to Section 3.4  hereof).  If any  certificates  representing  shares of
Company Common Stock entitled to payment  pursuant to Section 3.l shall not have
been  surrendered  for such  payment  prior to such date on which any payment in
respect  thereof  would  otherwise  escheat  to or become  the  property  of any
governmental agency or other governmental  entity, such shares of Company Common
Stock 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.

     Section 3.3 Dividends;  Transfer Taxes. No dividends or other distributions
that  are  declared  or made on  Parent  Common  Stock  will be paid to  persons
entitled to receive  certificates  representing  Parent Common Stock pursuant to
this  Merger   Agreement  until  such  persons   surrender  their   Certificates
representing  Company Common Stock. Upon such surrender,  there shall be paid to
the person in whose name the certificates  representing such Parent Common Stock
shall be issued any  dividends  or other  distributions  which shall have become
payable  with  respect to such Parent  Common  Stock in respect of a record date
after the Effective  Date. In no event shall the person entitled to receive such
dividends be entitled to receive  interest on such dividends.  In the event that
any  certificates  for any shares of Parent  Common  Stock are to be issued in a
name other than that in which the  Certificates  representing  shares of Company
Common Stock  surrendered  in exchange  therefor are  registered,  it shall be a
condition of such exchange that the  certificate or  certificates so surrendered
shall be properly  endorsed or be otherwise in proper form for transfer and that
the person requesting such exchange shall pay to the Exchange Agent any transfer
or other taxes  required  by reason of the  issuance  of  certificates  for such
shares of Parent Common Stock in a name other than that of the registered holder
of the Certificate  surrendered,  or shall establish to the  satisfaction of the
Exchange Agent that such tax has been paid or is not

applicable.  Notwithstanding  the foregoing,  neither the Exchange Agent nor any
party hereto  shall be liable to a holder of shares of Company  Common Stock for
any shares of Parent  Common  Stock or dividends  thereon  delivered to a public
official pursuant to any applicable escheat laws.

     Section 3.4 No Fractional  Shares.  No certificates  or scrip  representing
less than one share of Parent  Common  Stock shall be issued upon the  surrender
for exchange of  Certificates  representing  Company  Common  Stock  pursuant to
Section  3.1(b).  In lieu of any such fractional  share,  each holder of Company
Common Stock who would  otherwise have been entitled to a fraction of a share of
Parent  Common Stock upon  surrender of  Certificates  for exchange  pursuant to
Section 3.l(b) shall be paid upon such  surrender cash (without  interest) in an
amount equal to such  holder's  proportionate  interest in the net proceeds from
the sale or sales in the open  market by the  Exchange  Agent,  on behalf of all
such holders, of the aggregate fractional Parent Common Stock issued pursuant to
this Section 3.4. As soon as  practicable  following  the  Effective  Date,  the
Exchange  Agent shall  determine  the excess of (a) the number of full shares of
Parent  Common  Stock  delivered  to the  Exchange  Agent by Parent over (b) the
aggregate  number of full shares of Parent  Common  Stock to be  distributed  to
holders of Company  Common Stock (such  excess  being herein  called the "Excess
Shares"),  and the Exchange  Agent,  as agent for the former  holders of Company
Common Stock,  shall sell the Excess Shares at the prevailing  prices on the New
York Stock  Exchange  ("NYSE").  The sale of the Excess  Shares by the  Exchange
Agent shall be executed on the NYSE through one or more member firms of the NYSE
and shall be  executed  in round lots to the extent  practicable.  The  Exchange
Agent  shall  deduct  from the  proceeds  of the sale of the  Excess  Shares all
commissions, transfer taxes and other out-of-pocket transaction costs, including
the expenses and compensation of the Exchange Agent, incurred in connection with
such  sale of  Excess  Shares.  Until  the net  proceeds  of such sale have been
distributed to the former  stockholders of the Company,  the Exchange Agent will
hold  such  proceeds  in trust for such  former  stockholders  (the  "Fractional
Securities  Fund"). As soon as practicable after the determination of the amount
of  cash  to be  paid  to  former  stockholders  of the  Company  in lieu of any
fractional interests, the Exchange Agent shall make available in accordance with
this Agreement such amounts to such former stockholders.

     Section 3.5 Stock Options.

          (a) At or prior to the  Effective  Date,  the Company and Parent shall
take all action  necessary to cause the assumption by Parent as of the Effective
Date of all of the following which remain  outstanding as of the Effective Date:
(i) the options to purchase  Company  Common  Stock listed in Section 5.2 of the
Company  Disclosure  Schedule (as defined  below),  whether  vested or unvested,
issued under the Company's 1983  Non-qualified  and Incentive  Stock Option Plan
and 1991 Stock  Option  Plan  (collectively,  the "Stock  Option  Plans"),  (ii)
options to purchase  Company  Common  Stock listed in Section 5.2 of the Company
Disclosure  Schedule pursuant to option  agreements  outside of the Stock Option
Plans, and (iii) the warrants to purchase Company Common Stock listed in Section
5.2 of the Company  Disclosure  Schedule issued  pursuant to warrant  agreements
(collectively, the


<PAGE>



"Outstanding  Options").  To the extent  permitted under  applicable law and the
applicable  agreements and Stock Option Plans,  each of the Outstanding  Options
shall be converted  without any action on the part of the holder thereof into an
option to purchase  shares of Parent Common Stock as of the Effective  Date. The
number  of  shares  of  Parent  Common  Stock  that  the  holder  of an  assumed
Outstanding Option shall be entitled to receive upon the exercise of such option
shall be a number of whole and fractional  shares  determined by multiplying the
number of shares of Company  Common  Stock  subject to such  option,  determined
immediately before the Effective Date, by the Exchange Ratio. The exercise price
of each share of Parent Common Stock subject to an  Outstanding  Option shall be
the amount  (rounded up to the  nearest  whole  cent)  obtained by dividing  the
exercise  price  per  share of  Company  Common  Stock at which  such  option is
exercisable  immediately  before the Effective Date by the Exchange Ratio. Other
than as set forth in the Outstanding Options, the assumption and substitution of
options as provided herein shall not give the holders of such options additional
benefits or additional  vesting rights which they did not have immediately prior
to the Effective Date or relieve the holders of any  obligations or restrictions
applicable  to their  options  or the shares  obtainable  upon  exercise  of the
options.  Only whole shares of Parent Common Stock shall be issued upon exercise
of any  Outstanding  Option,  and in lieu of receiving any  fractional  share of
Parent Common Stock, the holder of such option shall, upon exercise,  receive in
cash the  fair  market  value of the  fractional  share,  net of the  applicable
exercise price of the fractional share and applicable  withholding  taxes. Prior
to the Effective  Date,  the Company shall take such  additional  actions as are
necessary  under  applicable law and the applicable  agreements and Stock Option
Plans to assure that each Outstanding Option shall, from and after the Effective
Date, represent only the right to urchase, upon exercise, whole shares of Parent
Common Stock and cash in lieu of any  fractional  share in  accordance  with the
provisions of this Section 3.5.

          (b)  After  the  Effective  Date,  the  Stock  Option  Plans  shall be
continued in effect by Parent  subject to amendment,  modification,  suspension,
abandonment or termination as provided therein, and the Stock Option Plans as so
continued (i) shall relate solely to those Outstanding Options that are governed
by such  Stock  Option  Plans  immediately  prior to the  Effective  Date,  (ii)
thereafter  shall relate only to the issuance of Parent Common Stock as provided
in this Section and (iii) shall continue to provide for equitable  adjustment in
the terms of Outstanding  Options in the event of certain corporate events which
alter the capital  structure of Parent.  Parent  shall  reserve for issuance the
number of shares of Parent  Common  Stock that will  become  issuable  after the
Effective  Date upon the exercise of the  Outstanding  Options  pursuant to this
Section 3.5. After the Effective Date,  Parent shall promptly notify the holders
of Outstanding  Options of the assumption by Parent of such options  pursuant to
this Merger Agreement.

     Section 3.6  Shareholders' Meetings.

          (a) The Company shall take all action  necessary,  in accordance  with
applicable law and its  Certificate of  Incorporation  and Bylaws,  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 Merger Agreement. Subject
to its fiduciary duties,  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  Merger  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 Merger Agreement.

          (b)  Parent  shall  take all  action  necessary,  in  accordance  with
applicable law and its  Certificate of  Incorporation  and Bylaws,  to convene a
special meeting of the holders of Parent Common Stock (the "Parent  Meeting") as
promptly as  practicable  for the purpose of  considering  and taking  action to
authorize the issuance of Parent  Common Stock  pursuant to the Merger under the
applicable guidelines of the NYSE (the "Parent Share Proposal").  Subject to its
fiduciary  duties,  as advised by outside  counsel,  the Board of  Directors  of
Parent will  recommend  that holders of Parent Common Stock vote in favor of and
approve the Parent Share Proposal at the Parent Meeting.

     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 full shares of Parent
Common  Stock as  provided  in  Section  3.1(b)  and cash in lieu of  fractional
shares, if any, as provided in Section 3.4.

     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 Merger  Agreement.
Parent shall cause Sub to perform all of its obligations in connection with this
Merger Agreement.

     Section 3.9 Closing.  The closing of the transactions  contemplated by this
Merger Agreement shall take place (a) at the offices of Gibson, Dunn & Crutcher,
200 Park Avenue,  New York,  New York 10166,  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 is  fulfilled or waived or (b) at such other
time and place as Parent and the Company shall agree in writing.

purposes (the "Parent Disclosure  Schedule"),  Parent represents and warrants to
the Company as follows:

     Section 4.1  Organization and  Qualification.  Parent is a corporation duly
organized,  validly existing and in good standing under the laws of the 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.  Parent 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 make such qualification necessary, except where the
failure to be so qualified will not,  individually  or in the aggregate,  have a
"Parent Material Adverse Effect" (as defined below).  As used in this Agreement,
a  "Parent  Material  Adverse  Effect"  shall  mean  any  event,   circumstance,
development  or occurrence,  individually  or when taken together with all other
such events, circumstances,  developments or occurrences,  causing, resulting in
or having, or reasonably likely to cause,  result in or have, a material adverse
effect on the condition (financial or otherwise), business, properties, business
relationships, prospects or results of operations of Parent and its subsidiaries
taken  as  a  whole.   Complete  and  correct  copies  of  the   Certificate  of
Incorporation  and Bylaws of Parent,  as amended to the date  hereof,  have been
delivered to the Company as attachments to Section 4.1 of the Parent  Disclosure
Schedule.

     Section 4.2 Capitalization. The authorized capital stock of Parent consists
of 100,000,000 shares of Parent Common Stock, and l ,000,000 shares of preferred
stock, $0.01 par value. As of March 17, 1995, 40,587,272 shares of Parent Common
Stock were validly issued and outstanding, fully paid, and nonassessable, and no
shares of  preferred  stock were issued and  outstanding,  and,  since that date
through  the  date of  execution  and  delivery  of this  Merger  Agreement,  no
additional  shares of capital  stock of Parent have been issued except shares of
Parent  Common Stock issued  pursuant to the exercise of stock  options or other
commitments  set  forth  herein  or in  Section  4.2  of the  Parent  Disclosure
Schedule. As of the date hereof, there are no bonds, debentures,  notes or other
indebtedness  having  the right to vote on any  matters  on which  the  Parent's
shareholders  may vote issued or outstanding.  As of March 17, 1995,  except for
options  to  acquire  4,497,477  shares of Parent  Common  Stock,  and except as
provided herein or in Section 4.2 of the Parent Disclosure  Schedule,  there are
no options, warrants, calls or other rights, agreements or commitments presently
outstanding  obligating  Parent to issue,  deliver or sell shares of its capital
stock or any debt securities or other instruments or rights  convertible into or
exchangeable  for such capital stock, or obligating  Parent to grant,  extend or
enter into any such  option,  warrant,  call or other such right,  agreement  or
commitment,  or to issue any such  convertible  or  exchangeable  debt security,
instrument  or right and,  since that date  through  the date of  execution  and
delivery of this Merger  Agreement,  no such options,  warrants,  calls or other
rights,  agreements or commitments,  or such  convertible or  exchangeable  debt
securities,  instruments  or other rights have been  issued,  granted or entered
into except for the grant of additional stock options pursuant to Parent's stock
plans. All of the shares of Parent Common Stock issuable in accordance with this
Merger  Agreement in exchange for Company  Common Stock at the Effective Date in
accordance with this Merger Agreement will be, when so issued, duly


<PAGE>



authorized,  validly issued, fully paid and nonassessable and shall be delivered
free and clear of all liens,  claims,  charges and  encumbrances  of any kind or
nature whatsoever, including any preemptive rights of any stockholder of Parent.
There  are no  obligations,  contingent  or  otherwise,  of Parent or any of its
Significant  Subsidiaries (as defined below) to repurchase,  redeem or otherwise
acquire any shares of capital stock of Parent or any  Significant  Subsidiary of
Parent.

     Section 4.3  Subsidiaries.  Section 4.3 of the Parent  Disclosure  Schedule
lists the only "Significant  Subsidiaries" (as such term is defined in Rule 1-02
of Regulation S-X of the Securities and Exchange  Commission (the "Commission"))
("Significant  Subsidiaries")  owned  directly  or  indirectly  by Parent.  Each
Significant Subsidiary is a corporation duly organized,  validly existing and in
good standing under the laws of its  jurisdiction of  incorporation  and has the
corporate  power  to carry  on its  business  as it is now  being  conducted  or
currently  proposed  to  be  conducted.  Each  Significant  Subsidiary  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  will not have a Parent  Material  Adverse
Effect.  All the  outstanding  shares  of  capital  stock  of  each  Significant
Subsidiary are validly issued,  fully paid and  nonassessable and those owned by
Parent or by a Significant  Subsidiary of Parent are owned free and clear of any
liens, claims or encumbrances. 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  Significant
Subsidiaries  of  Parent.  Parent has made  available  to the  Company  true and
complete  copies of the  charter and bylaws,  in the case of a  corporation,  or
equivalent governing document, in the case of non-corporate  entities,  for each
corporation,. partnership, joint venture or other business association or entity
owned,  directly  or  indirectly,  by Parent  that is material to Parent and its
subsidiaries taken as a whole.

     Section 4.4  Authority  Relative to This Merger  Agreement.  Parent has the
corporate  power  to enter  into  this  Merger  Agreement  and to carry  out its
obligations  hereunder.  The execution and delivery of this Merger Agreement and
the  consummation  of  the  transactions  contemplated  hereby  have  been  duly
authorized by Parent's Board of Directors.  The Merger  Agreement  constitutes a
valid and binding  obligation of Parent enforceable in accordance with its terms
except as enforcement may 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 discretion of the court before which any proceeding  therefor may
be brought.  Except for the  approval of the holders of the Parent  Common Stock
described  in Section  3.6(b),  no other  corporate  proceedings  on the part of
Parent are  necessary to authorize  the Merger  Agreement  and the  transactions
contemplated hereby. Except as disclosed in Section 4.4 of the Parent Disclosure
Schedule,  Parent is not subject to or obligated  under (a) any charter or bylaw
provision,  or (b)  any  indenture  or  other  loan  document  provision,  other
contract,  license,  franchise,   permit,  order,  decree,  concession,   lease,
instrument,  judgment, statute, law, ordinance, rule or regulation applicable to
Parent 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 or acceleration of
any obligation or the loss of a material benefit,  by its executing and carrying
out this  Merger  Agreement  other than in the case of clause (b) only,  (i) any
breaches, violations,  defaults, terminations,  cancellations,  accelerations or
losses which, either singly or in the aggregate, will not have a Parent Material
Adverse  Effect or prevent the  consummation  of the  transactions  contemplated
hereby  and  (ii) the laws and  regulations  referred  to in the next  sentence.
Except as disclosed in Section 4.4 of the Parent Disclosure  Schedule and except
for  compliance   with  the  provisions  of  the   Hart-Scott-Rodino   Antitrust
Improvements  Act of 1976,  as amended (the "HSR Act"),  the  Securities  Act of
1933, as amended (the "Securities Act"), the Securities Exchange Act of 1934, as

authorization, consent or approval of, any public body or authority is necessary
for  the  consummation  by  Parent  of  the  Merger  or the  other  transactions
contemplated  by this  Merger  Agreement,  other  than  filings,  registrations,
authorizations,  consents  or  approvals  the failure of which to make or obtain
would not have a Parent Material  Adverse Effect or prevent the  consummation of
the transactions contemplated hereby.

insurance and health commissions,  except for such permits, licenses, variances,

Parent  Material  Adverse  Effect  (the  "Parent   Permits").   Parent  and  its
Significant Subsidiaries are in compliance with the terms of the Parent Permits,

have a Parent  Material  Adverse  Effect.  Except as disclosed in the Parent SEC

Form 10-Q for the quarter  ended  September  30,  1994 or in the 1994  Financial
Statements or (b) for liabilities or obligations incurred in the ordinary course
of business  since  December  31,  1994,  that would not have a Parent  Material
Adverse Effect.

     Section 4.14 Accounting Matters. Neither Parent nor, to its best knowledge,
any of its affiliates,  has through the date hereof, taken or agreed to take any
action that would prevent the business  combination to be effected by the Merger
from being  accounted  for as a "pooling of  interests."  Parent has  received a
letter  from  Coopers & Lybrand  L.L.P.,  a copy of which is attached to Section
4.14 of the  Parent  Disclosure  Schedule,  to the effect  that the Merger  will
qualify for  "pooling of  interests"  accounting  treatment  if  consummated  in
accordance  with this Merger  Agreement and if the  operations of Parent and the
Surviving  Corporation are conducted in a manner that do not violate "pooling of
interests" accounting treatment.

     Section 4.15 Environmental Liability.

          (a) The  businesses of Parent and its  Significant  Subsidiaries  have
been and are operated in material  compliance  with all applicable  statutory or
regulatory  requirements of all Governmental Entities with jurisdiction over the
environment or over workplace  health and safety,  and neither Parent nor any of
its Significant  Subsidiaries  has caused or allowed the generation,  treatment,
storage,  release or disposal of hazardous  substances except in accordance with
such statutes and  regulations  as they existed at the time of such  generation,
treatment, storage, release or disposal.

          (b) Neither Parent nor its Significant  Subsidiaries  has received any
written  notice or, to the best  knowledge of Parent,  any other  communication,
from any Governmental Entities alleging or concerning any violation by Parent or
any of its Significant Subsidiaries of,


<PAGE>



or responsibility  or liability of Parent or any of its Significant Subsidiaries
under,  any  statute or  regulation  relating to the  environment.  There are no
pending  or,  to the  best  knowledge  of  Parent,  threatened,  claims,  suits,
proceedings  or  investigations  with respect to the businesses or operations of
Parent  or  any of its  Significant  Subsidiaries  alleging  or  concerning  any
violation of or  responsibility  or liability  under any statutes or regulations
relating to the  environment,  nor does Parent have any knowledge of any fact or
condition which might reasonably be expected to give rise to such a claim, suit,
proceeding or investigation.

          (c) Parent and its Significant  Subsidiaries  are in possession of all
material  approvals,  permits and licenses from all Governmental  Entities under
statutes and regulations relating to the environment and to workplace health and
safety  with  respect  to the  operation  of the  businesses  of Parent  and its
Significant  Subsidiaries;  there are no pending  or, to the best  knowledge  of
Parent, threatened,  actions, proceedings or investigations seeking to revoke or
deny renewal of any of such  approvals,  permits and  licenses;  nor does Parent
have  knowledge of any fact or condition  which might  reasonably be expected to
give rise to any action,  proceeding or  investigation to revoke or deny renewal
of such  approvals,  permits or  licenses  if such  revocation  or denial  would
constitute a Parent Material Adverse Effect.

     Section 4.16 Certain  Relationships.  All  billings  made to customers  and
suppliers of Parent or any Significant  Subsidiary  have been properly  computed
and billed in compliance with applicable laws,  rules,  regulations,  agreements
and procedures,  and no such customer has any right to any refund,  price or fee
adjustments,  offsets or similar right with respect to any such charges,  except
where the  failure  to so comply or the  amount of such  right  would not have a
Parent Material Adverse Effect.

     Section 4.17 Certain Healthcare Regulatory Matters.

          (a) To the  best  knowledge  of  Parent,  Parent  and its  Significant
Subsidiaries  have not engaged  knowingly and willfully in any activities  which
are prohibited under federal Medicare and Medicaid statutes,  including, without
limitation,  42 U.S.C.  Section 1320a-7b and 42 U.S.C. Section 1395nn or related
state or local  statutes or regulations or which  otherwise  constitutes  fraud,
including, without limitation, the following: (i) knowingly and willfully making
or causing to be made a false statement or  representation of a material fact in
any application for any benefit or payment;  (ii) knowingly and willfully making
or causing to be made any false statement or  representation  of a material fact
for use in  determining  rights to any benefit or payment;  (iii)  knowingly and
willfully failing to disclose knowledge of the occurrence of any event affecting
the  initial or  continued  right to any  benefit or payment on its behalf or on
behalf of another,  with intent to secure such benefit or payment  fraudulently;
(iv) knowingly and willfully soliciting or receiving any remuneration (including
any kickback, bribe, or rebate), directly or indirectly, overtly or covertly, in
cash or in kind or offering to pay such remuneration (A) in return for referring
an individual to a person for the  furnishing or arranging for the furnishing of
any  item or  service  for  which  payment  may be made in  whole  or in part by
Medicare or Medicaid or (B) in return for purchasing, leasing, or


<PAGE>



ordering or arranging for or  recommending  purchasing,  leasing or ordering any
good,  facility,  service or item for which  payment  may be made in whole or in
part by Medicare or Medicaid.

          (b) Parent and its Significant  Subsidiaries  have complied and are in
compliance,  in all material  respects,  with  applicable  state laws regulating
pharmacies.

     Section 4.18  Certain  Agreements.  Section  4.18 of the Parent  Disclosure
Schedule contains a list of each contract,  agreement and understanding with any
customer or supplier of Parent or any Significant Subsidiary that is material to
the business of Parent and its subsidiaries taken as a whole.

                                ARTICLE V
               REPRESENTATIONS AND WARRANTIES OF THE COMPANY

     Except as disclosed in the schedule  delivered to Parent  concurrently with
the  execution  hereof,  which  schedule  shall  identify  exceptions  and other
information by specific Section references and shall be initialed by Company and
the Parent for identification purposes (the "Company Disclosure Schedule"),  the
Company represents and warrants to Parent and Sub as follows:

     Section 5.1  Organization and  Qualification.  The Company is a corporation
duly  organized,  validly  existing and in good  standing  under the laws of the
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 necessary, except
where the failure to be so qualified will not have a "Company  Material  Adverse
Effect" (as  defined  below).  As used in this  Agreement,  a "Company  Material
Adverse Effect" shall mean any event,  circumstance,  development or occurrence,
individually  or when taken together with all other such events,  circumstances,
developments  or  occurrences,  causing,  resulting in or having,  or reasonably
likely to cause,  result in or have, a material  adverse effect on the condition
(financial  or  otherwise),   business,   properties,   business  relationships,
prospects or results of  operations of Company and its  subsidiaries  taken as a
whole.  Complete and correct  copies of the  Certificate  of  Incorporation  and
Bylaws of the Company,  Diagnostek Pharmacy Services, Inc. ("DPSI"), Health Care
Services, Inc. ("HCS") and HPI Health Care Services, Inc. ("HPI"), as amended to
the date hereof,  have been delivered to Parent as attachments to Section 5.1 of
the Company Disclosure Schedule.

     Section 5.2  Capitalization.  The  authorized  capital stock of the Company
consists of 45,000,000  shares of Company  Common Stock and 5,000,000  shares of
preferred  stock,  $0.01 par value. As of March 22, 1995,  24,238,246  shares of
Company  Common  Stock  were  validly  issued  and  outstanding,  fully paid and
nonassessable, 111,989 shares of Company Common Stock were held in treasury, and
no shares of  preferred  stock  were  outstanding,  and,  since  that  date,  no
additional shares of capital stock of Company have been


<PAGE>



issued except shares of Company Common Stock issued  pursuant to the exercise of
stock  options  or other  commitments  set forth in Section  5.2 of the  Company
Disclosure  Schedule.  As of the date  hereof,  there are no bonds,  debentures,
notes or other indebtedness having the right to vote on any matters on which the
Company's  shareholders  may vote issued or outstanding.  Except as set forth in
Section 5.2 of the Company Disclosure Schedule, there are no options,  warrants,
calls or other rights,  agreements or  commitments  outstanding  obligating  the
Company  to  issue,  deliver  or sell  shares of its  capital  stock or any debt
securities or other  instruments or rights  convertible into or exchangeable for
such capital stock, or obligating the Company to grant, extend or enter into any
such option,  warrant, call or other such right, agreement or commitment,  or to
issue any such convertible or exchangeable  debt security,  instrument or right.
There are no obligations,  contingent or otherwise, of the Company or any of its
subsidiaries  to repurchase,  redeem or otherwise  acquire any shares of capital
stock of the Company or any subsidiary of the Company. The Company has delivered
to  Parent  complete  and  correct  copies  of (a) the  1983  Non-qualified  and
Incentive  Stock Option Plan and the 1991 Stock Option Plan,  and all amendments
thereto,  and (b) each form of stock option agreement and warrant agreement used
by the Company with respect to the Outstanding Options.

     Section 5.3 Subsidiaries.  Section 5.3 of the Company  Disclosure  Schedule
lists all  subsidiaries  of the Company.  Each such  subsidiary is a corporation
duly  organized,  validly  existing and in good  standing  under the laws of its
jurisdiction  of  incorporation  and has the  corporate  power  to  carry on its
business as it is now being  conducted  or currently  proposed to be  conducted.
Each such subsidiary 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  will not
have a Company  Material Adverse Effect.  All the outstanding  shares of capital
stock of each such subsidiary 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.  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
such subsidiaries.  Except as disclosed in Section 5.3 of the Company Disclosure
Schedule and except for wholly  owned  subsidiaries  the  formation of which was
approved  pursuant to Section  7.1(f)  hereof,  the Company does not directly or
indirectly own any interest in any other corporation, partnership, joint venture
or other business association or entity.

     Section 5.4 Authority  Relative to This Merger  Agreement.  The Company has
the corporate power to enter into this Merger Agreement and, subject to approval
of this  Agreement  by the  holders of Company  Common  Stock,  to carry out its
obligations  hereunder.  The execution and delivery of this Merger Agreement and
the  consummation  of  the  transactions  contemplated  hereby  have  been  duly
authorized  by  the  Company's  Board  of  Directors.   This  Merger   Agreement
constitutes  a valid  and  binding  obligation  of the  Company  enforceable  in
accordance  with its terms except as  enforcement  may be limited by bankruptcy,
insolvency or other similar laws affecting the enforcement of creditors'  rights
generally and


<PAGE>



except  that  the  availability  of  equitable   remedies,   including  specific
performance,  is  subject  to the  discretion  of the  court  before  which  any
proceeding  therefor  may be brought.  Except for the approval of the holders of
Company Common Stock, no other corporate  proceedings on the part of the Company
are  necessary  to  authorize  this  Merger   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 (a) any
charter  or  bylaw  provision,  or (b) any  indenture  or  other  loan  document
provision,   other  contract,   license,   franchise,   permit,  order,  decree,
concession,  lease,  instrument,  judgment,  statute,  law,  ordinance,  rule or
regulation  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 or
acceleration  of any  obligation  or the  loss  of a  material  benefit,  by its
executing  and carrying out this Merger  Agreement,  other than,  in the case of
clause  (b)  only,  (A)  any  breaches,  violations,   defaults,   terminations,
cancellations, accelerations or losses which, either singly or in the aggregate,
will not 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
would not have a Company  Material Adverse Effect or prevent the consummation of
the transactions contemplated hereby.

     Section 5.5 Reports and Financial Statements.

          (a) The Company has previously furnished Parent with true and complete
copies of its (i) Annual  Reports on Form 10-K for the fiscal  years ended March
31, 1993 and 1994, as filed with the Commission  (and any  amendments  thereto),
(ii) Quarterly Reports on Form 10-Q for the fiscal quarters ended June 30, 1994,

thereto) related to all meetings of its shareholders (whether annual or special)
since April 1, 1994 and (iv) all other  reports  filed by the  Company  with the
Commission  since  March 31,  1994,  which  are all the  documents  (other  than
preliminary  material) that the Company was required to file with the Commission
pursuant to the Exchange  Act and the rules and  regulations  of the  Commission
thereunder  since that date  (clauses (i) through (iv) being  referred to herein
collectively as the "Company SEC Reports").  As of their  respective  dates, the
Company SEC Reports  complied in all material  respects with the requirements of
the  Exchange Act 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


<PAGE>



omit to state a material fact required to be stated therein or necessary to make
the  statements  therein,  in light of the  circumstances  under which they were
made,  not  misleading.   The  audited  consolidated  financial  statements  and
unaudited  interim  financial  statements of the Company included in the Company
SEC  Reports  comply  in  all  material  respects  with  applicable   accounting
requirements and with the published rules and regulations of the Commission with
respect thereto.  The financial  statements included in the Company SEC Reports:
have been prepared in accordance with generally accepted  accounting  principles
applied on a  consistent  basis  (except as may be  indicated  therein or in the
notes thereto); present fairly, in all material respects, the financial position
of the Company and its  subsidiaries  as at the dates thereof and the results of
their  operations and cash flow for the periods then ended subject,  in the case
of  the  unaudited  interim  financial  statements,  to  normal  year-end  audit
adjustments  and any  other  adjustments  described  therein  and the fact  that
certain  information and notes have been condensed or omitted in accordance with
the Exchange Act and the rules promulgated  thereunder;  and are in all material
respects, in accordance with the books of account and records of the Company.

          (b) The audited  consolidated  financial statements of the Company for
the fiscal year ended March 31, 1995 (the "1995 Financial Statements") delivered
to Parent pursuant to Section 9.3(d) hereof comply in all material respects with
applicable accounting  requirements and with the published rules and regulations
of the Commission with respect thereto.  The 1995 Financial Statements have been
prepared in accordance with generally accepted accounting  principles applied on
a consistent basis (except as may be indicated therein or in the notes thereto);
present fairly, in all material respects,  the financial position of the Company
and its  subsidiaries  as at March 31, 1995 and the results of their  operations
and cash flow for the fiscal year then ended; and are in all material  respects,
in accordance with the books of account and records of the Company.  The parties
hereto  acknowledge  that the  representation  and  warranty  contained  in this
Section  5.5(b)  shall  not be  effective  until  the date  the  1995  Financial
Statements are delivered to Parent pursuant to Section 9.3(d) hereof.

     Section 5.6 Absence of Certain  Changes or Events.  Except as  disclosed in
the Company SEC Reports or as disclosed in Section 5.6 of the Company Disclosure
Schedule,  since March 31, 1994, there has not been any Company Material Adverse
Effect  (other  than as a result of  changes in laws or  regulations  of general
applicability).

     Section 5.7  Litigation.  Except 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,  is likely, insofar as the
Company reasonably  foresees,  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
specifically  against the Company or any of its subsidiaries  having,  or which,
insofar as the Company  reasonably  foresees,  in the future could have,  either
alone or in the aggregate, a Company Material Adverse Effect.

     Section 5.8 Information in Disclosure Documents.



<PAGE>



          (a) None of the information concerning the Company or its subsidiaries
to be  included or  incorporated  by  reference  in the Proxy  Statement  or the
Registration  Statement  will,  in  the  case  of  the  Proxy  Statement  or any
amendments  or  supplements  thereto,  at the time of the  mailing  of the Proxy
Statement and any  amendments  or  supplements  thereto,  and at the time of the
Meeting of holders of Company  Common  Stock to be held in  connection  with the
Merger,  or, in the case of the Registration  Statement,  at the time it becomes
effective and at the Effective Date,  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 will comply as to
form in all material  respects  with the  provisions of the Exchange Act and the
rules and regulations thereunder.  The foregoing  representations and warranties
of  Company  contained  in this  Section  5.8  shall  in no  event  apply to any
statements  or omissions in the  Registration  Statement or the Proxy  Statement
based upon information provided by Parent for use therein.

          (b) No  representation  or warranty  made by the Company  contained in
this Agreement and no statement  contained in any certificate,  list, exhibit or
other instrument  specified in this Agreement,  including without limitation the
Company Disclosure Schedule, contains any untrue statement of a material fact or
omits or will omit to state a material  fact  necessary  to make the  statements
contained therein, in light of the circumstances under which they were made, not
misleading.

     Section 5.9 Employee Benefit Plans.  Except as disclosed in the Company SEC
Reports or in  Section  5.9 of the  Company  Disclosure  Schedule,  there are no
employee  benefit or compensation  plans or  arrangements,  including  "employee
benefit  plans," as defined in Section  3(3) of ERISA,  and  including,  but not
limited to, plans or arrangements relating to former employees,  including,  but
not  limited  to,  retiree  medical  plans,  established  or  maintained  by  or
contributed to by the Company or any of its subsidiaries or "ERISA  Affiliates",
or  collective  bargaining  agreements  to  which  the  Company  or  any  of its
subsidiaries  is a party  (together,  the "Company  Benefit  Plans").  An "ERISA
Affiliate"  shall mean any  corporation or trade or business that is a member of
any group of organizations  (i) described in Section 4.14(b) or (c) of the Code,
of which the Company is a member and (ii) described in Section 4.14(m) or (o) of
the  Code,  of which  the  Company  is a member.  To the best  knowledge  of the
Company, no default exists with respect to the obligations of the Company or any
of its  subsidiaries or ERISA  Affiliates under such Company Benefit Plan, which
default,  alone or in the  aggregate,  would  have a  Company  Material  Adverse
Effect.  Except as disclosed in Section 5.9 of the Company Disclosure  Schedule,
there are no disputes or grievances subject to any grievance  procedure,  unfair
labor practice proceedings, arbitration or litigation under such Company Benefit
Plans,  which have not been finally resolved,  settled or otherwise disposed of,
nor is there any default,  or any condition which,  with notice or lapse of time
or both, would  constitute such a default,  under any such Plans, by the Company
or its subsidiaries or ERISA Affiliates or, to the best knowledge of the Company
and its subsidiaries,  any other party thereto, which failure to resolve, settle
or otherwise dispose of, or which default, alone or in the aggregate, would have
a Company


<PAGE>



Material  Adverse Effect.  Since December 31, 1994,  there have been no strikes,
lockouts or work stoppages or slowdowns, or to the best knowledge of the Company
and its subsidiaries,  jurisdictional disputes or except as set forth in Section
5.9  of  the  Company  Disclosure  Schedule  organizing  activity  occurring  or
threatened  with  respect to the  business or  operations  of the Company or its
subsidiaries which have had or would have a Company Material Adverse Effect.

     Section 5.10 ERISA.  All Company  Benefit Plans have been  administered  in
accordance,  and are in  compliance,  with the  applicable  provisions of ERISA,
except  where such  failures to  administer  or comply  would not have a Company
Material  Adverse  Effect.  Except as  disclosed  in Section 5.10 of the Company
Disclosure Schedule, each of the Company Benefit Plans which is intended to meet
the  requirements  of  Section  401(a)  of the Code has been  determined  by the
Internal  Revenue Service to be "qualified,"  within the meaning of such section
of the Code, and the Company knows of no fact which is likely to have an adverse
effect on the  qualified  status of such plans.  Except with respect to the SEIU
Local 36 Pension Plan as to which the Company makes no  representation,  none of
the Company  Benefit Plans which are defined benefit pension plans have incurred
any  "accumulated  funding  deficiency"  (whether or not waived) as that term is
defined in Section  412 of the Code and the fair  market  value of the assets of
each such plan equal or exceed the accrued liabilities of such plan. To the best
knowledge of the Company,  except with respect to the SEIU Local 36 Pension Plan
as to which  the  Company  makes no  representation,  there are not now nor have
there been any non-exempt "prohibited  transactions," as such term is defined in
Section  4975 of the Code or  Section  406 of  ERISA,  involving  the  Company's
Benefit  Plans  which  could  subject  the  Company,  its  subsidiaries,   ERISA
Affiliates or Parent to the penalty or tax imposed under Section 502(i) of ERISA
or Section 4975 of the Code.  No Company  Benefit Plan which is subject to Title
IV of ERISA has been  completely  or partially  terminated;  no  proceedings  to
completely or partially  terminate any Company Benefit Plan have been instituted
within the  meaning of Subtitle C of said Title IV of ERISA;  and no  reportable
event  within the  meaning of  Section  4043(b) of said  Subtitle C of ERISA has
occurred with respect to any Company Benefit Plan except,  in each case that the
Company makes no representation  with respect to the SEIU Local 36 Pension Plan.
Neither the Company nor any of its  subsidiaries or ERISA  Affiliates has made a
complete or partial  withdrawal,  within the  meaning of Section  4201 of ERISA,
from any multiemployer plan which has resulted in, or is reasonably  expected to
result in, any  withdrawal  liability to the Company or any of its  subsidiaries
except for any such liability  which would not have a Company  Material  Adverse
Effect.  Neither the Company nor any of its subsidiaries or ERISA Affiliates has
engaged in any  transaction  described  in Section 4069 of ERISA within the last
five  years  except  for any such  transaction  which  would  not have a Company
Material Adverse Effect.

     Section 5.11 Takeover Provisions Inapplicable.  Assuming the representation
in Section 4.9 is  accurate,  as of the date hereof and at all times on or prior
to the Effective Date, Section 203 of the DGCL is, and shall be, inapplicable to
the Merger and the transactions contemplated by this Merger Agreement.


<PAGE>



     Section 5.12 Fairness Opinion. The Company has received the written opinion
of  Lazard  Freres & Co.,  financial  advisors  to the  Company,  dated the date
hereof,  to the effect that the  consideration  to be received by the  Company's
shareholders  is fair to the  shareholders of the Company from a financial point
of view.

     Section 5.13 Financial  Advisor.  The Company represents and warrants that,
(a) except for Lazard Freres & Co., no broker,  finder or  investment  banker is
entitled to any  brokerage,  finder's or other fee or  commission  in connection
with the Merger or the transactions  contemplated by this Merger Agreement based
upon  arrangements  made by or on  behalf of the  Company,  and (b) the fees and
commissions payable to Lazard Freres & Co., as contemplated by this Section will
not exceed the  aggregate  amount set forth in the letter  dated March 15, 1995,
from Lazard  Freres & Co. to the Company (a complete  and correct  copy of which
has been  delivered  to Parent as an  attachment  to Section 5.13 of the Company
Disclosure Schedule).

     Section  5.14  Compliance  with  Applicable   Laws.  The  Company  and  its
subsidiaries  hold all  permits,  licenses,  variances,  exemptions,  orders and
approvals  of  all  Governmental   Entities,   including,   without  limitation,
applicable  state  insurance  and health  commissions,  except for such permits,
licenses,  variances,  exemptions,  orders and approvals the failure of which to
hold would not have a Company Material  Adverse Effect (the "Company  Permits").
The Company and its subsidiaries are in compliance with the terms of the Company
Permits,  except for such failures to comply,  which singly or in the aggregate,
would not have a Company  Material  Adverse  Effect.  Except as disclosed in the
Company SEC  Reports  filed  prior to the date of this  Merger  Agreement  or in
Section 5.14 of the Company Disclosure  Schedule,  the businesses of the Company
and its subsidiaries are not being conducted in violation of any law,  ordinance
or  regulation  of  any  Governmental  Entity,  including,  without  limitation,
applicable  state  insurance  and  health   commissions,   except  for  possible
violations  which  individually  or in the aggregate do not and would not have a
Company  Material  Adverse  Effect.  Except as  disclosed in Section 5.14 of the
Company  Disclosure  Schedule,  no  investigation  or review by any Governmental
Entity,  including,  without  limitation,  applicable state insurance and health
commissions,  with respect to the Company or any of its subsidiaries is pending,
or,  to the  knowledge  of the  Company,  threatened,  nor has any  Governmental
Entity,  including,  without  limitation,  applicable state insurance and health
commissions,  indicated an  intention to conduct the same,  other than those the
outcome of which would not have a Company Material Adverse Effect.

     Section  5.15  Liabilities.  Except as  disclosed  in  Section  5.15 of the
Company Disclosure Schedule, neither the Company nor any of its subsidiaries has
any material  liabilities  or  obligations  (absolute,  accrued,  contingent  or
otherwise) that would be required to be reflected on, or reserved  against in, a

or  obligations  incurred in the ordinary  course of business since December 31,
1994, that would not have a Company Material Adverse Effect.

     Section 5.16 Taxes.  Each of the Company and its subsidiaries has filed all
tax returns (including,  without limitation,  estimated tax returns) required to
be filed by any of them (other than for returns,  the due date for the filing of
which,  including  extensions,  has not yet passed) and has paid (or the Company
has paid on its behalf),  or has set up an adequate  reserve for the payment of,
all taxes (including,  without limitation,  estimated taxes) required to be paid
in respect of the periods  covered by such returns (except (a) where the failure
to pay would  not have a Company  Material  Adverse  Effect,  (b) in the case of
failure to file any return with any state or local taxing  authority (other than
any return  required to be filed with respect to income taxes,  franchise  taxes
imposed  in lieu of  income  taxes,  sales  taxes  and  employment  taxes by the
Company, DPSI, HCS or HPI with the States of Arizona,  California and New Mexico
and the  Commonwealth  of  Pennsylvania),  where such  failure  would not have a
Company  Material  Adverse  Effect  and (c) in the case of  failure  to file any
return  required  to be filed with  respect  to income  taxes,  franchise  taxes
imposed  in lieu of  income  taxes,  sales  taxes  and  employment  taxes by the
Company, DPSI, HCS or HPI with the States of Arizona,  California and New Mexico
and the Commonwealth of Pennsylvania,  where such failures would not subject the
Company and such  subsidiaries  to liability  attributable  solely to failure to
file in excess of $100,000 in the aggregate).  The information contained in such
tax returns is true,  complete  and  accurate,  except  where a failure to be so
would not have a Company Material Adverse Effect. Except as disclosed in Section
5.16 of the Company Disclosure Schedule,  neither the Company nor any subsidiary
of  the  Company  is  delinquent  in  the  payment  of any  tax,  assessment  or
governmental  charge,  except  where such  delinquency  would not have a Company
Material  Adverse  Effect.  Except as  disclosed  in Section 5.16 of the Company
Disclosure Schedule, no deficiencies for any taxes have been proposed,  asserted
or assessed  against the Company or any of its  subsidiaries  that have not been
finally  settled or paid in full,  which would have a Company  Material  Adverse
Effect,  and no  requests  for  waivers  of the time to assess  any such tax are
pending.  The  federal  income  tax  returns  of the  Company  and  each  of its
subsidiaries  consolidated  in such returns for periods  through  March 31, 1990
have been  examined  by and settled  with the  Internal  Revenue  Service or are
considered closed years for federal income tax purposes. Neither the Company nor
any  of its  subsidiaries  is a  party  to or  obligated  under  any  agreement,
commitment  or  arrangement  that  could in  connection  with  the  transactions
contemplated hereby require the payment of any "excess parachute payment" within
the  meaning of section  280G of the Code.  Neither  the  Company nor any of its
subsidiaries (a) has filed a consent under section 341(f) of the Code concerning
collapsible  corporations  or (b)  been a  member  of an  affiliated,  combined,
unitary group, other than a group the common parent of which is the Company,  or
has any  liability  for  taxes of any other  person  under  Treasury  Regulation
section  1.1502-6 or any similar  provision  of state,  local or foreign law, as
transferee  or  successor,  by contract or  otherwise.  For the purposes of this
Merger  Agreement,  the term "tax" shall include all federal,  state,  local and
foreign income, profits,  franchise, gross receipts, payroll, sales, employment,
use, property,  withholding,  excise and other taxes,  duties and assessments of
any nature  whatsoever  together  with all  interest,  penalties  and  additions
imposed with respect to such amounts.

     Section 5.17 Certain Agreements.

          (a) Except as disclosed in the Company SEC Reports  filed prior to the
date of this  Merger  Agreement  or in Section  5.17 of the  Company  Disclosure
Schedule, neither the Company nor any of its subsidiaries is a party to any oral
or written (i) agreement,  contract,  indenture or other instrument  relating to
Indebtedness (as defined below) in an amount outstanding  exceeding  $1,000,000,
(ii) agreement which,  after giving effect to the  transactions  contemplated by
this  Merger  Agreement,  purports  to  restrict  or bind  Parent  or any of its
subsidiaries (other than the Surviving Corporation and its subsidiaries but only
to the extent such  agreement  would bind or restrict the Company  and/or one or
more of its  subsidiaries  without  regard to the  consummation  of this  Merger
Agreement) in any respect that could have a Parent  Material  Adverse  Effect or
(iii)  contract,  agreement  or  commitment  (except  those  entered into in the
ordinary  course of business)  having a Company  Material  Adverse  Effect.  For
purposes of this Merger Agreement, "Indebtedness" means any liability in respect
of (A) borrowed  money,  (B)  capitalized  lease  obligations,  (C) the deferred
purchase  price of  property  or  services  (other  than trade  payables  in the
ordinary course of business) and (D) guarantees of any of the foregoing.  Except
as  disclosed in Section 5.17 of the Company  Disclosure  Schedule,  neither the
Company nor any of its  subsidiaries  is in default (or would be in default with
notice or lapse of time, or both) under any indenture,  note,  credit agreement,
loan document,  lease, license or other agreement including, but not limited to,
any Company  Benefit  Plan,  whether or not such default has been waived,  which
default,  alone or in the  aggregate  with  other  such  defaults,  would have a
Company Material Adverse Effect.

          (b) Section 5.17 of the Company Disclosure Schedule contains a list of
(i) each of the customers of HCS who as a group constitute such  subsidiary's 30
highest revenue producing customers for the nine months ended December 31, 1994,
(ii) each of the customers of HPI who as a group constitute such subsidiary's 30
highest revenue producing  customers for the nine months ended December 31, 1994
and  (iii)  each  of  the  pharmaceutical  suppliers  of  the  Company  and  its
subsidiaries who as a group  constitute the 30 most  significant  pharmaceutical
suppliers to the Company and its  subsidiaries  taken as a whole (as measured by
the dollar amounts paid to such pharmaceutical  suppliers during the nine months
ended December 31, 1994).

          (c) The Company has made  available to Parent a true and complete copy
of each  agreement  between the Company or any subsidiary of the Company and any
employee  or  consultant  which (i) in any year  could  involve  the  payment of
$50,000 or more to any such employee, or $100,000 or more to any such consultant
or (ii) is not terminable by the Company or a subsidiary of the Company  without
additional liability upon notice of 90 days or less.

     Section 5.18  Patents,  Trademarks,  etc. The Company and its  subsidiaries
have all  patents,  trademarks,  trade  names,  service  marks,  trade  secrets,
copyrights and licenses and other proprietary  intellectual  property rights and
licenses as are necessary in connection  with the  businesses of the Company and
its  subsidiaries,  the lack of which  would  have a  Company  Material  Adverse
Effect, and except as disclosed in Section 5.18 of the


<PAGE>



Company  Disclosure  Statement,  the Company does not have any  knowledge of any
conflict  with the rights of the  Company  and its  subsidiaries  therein or any
knowledge  of any  conflict  by them with the  rights of others  therein  which,
insofar as reasonably  can be foreseen,  could have a Company  Material  Adverse
Effect.

     Section  5.19  Accounting  Matters.  Neither the  Company  nor, to its best
knowledge,  any of its affiliates,  has through the date hereof, taken or agreed
to take any action that would prevent  Parent from  accounting  for the business
combination  to be  effected  by the Merger as a  "pooling  of  interests."  The
Company  has  received a letter from KPMG Peat  Marwick  LLP, a copy of which is
attached to Section 5.19 of the Company Disclosure Schedule,  to the effect that
the Merger will  qualify for  "pooling of  interests"  accounting  treatment  if
consummated  in accordance  with this Merger  Agreement and if the operations of
Parent and the  Surviving  Corporation  are  conducted  in a manner  that do not
violate "pooling of interests" accounting treatment.

     Section 5.20  Investment  Company  Act.  The Company is not an  "investment
company" within the meaning of the Investment Company Act of 1940.

     Section 5.21  Properties,  Liens.  The Company and its  subsidiaries own or
lease all of their  respective  tangible  and  intangible  properties,  real and
personal,  free and  clear  of any  liens,  claims,  charges,  options  or other
encumbrance (it being understood that, with respect to leased  properties,  such
representation regarding the absence of liens, claims, charges, options or other
encumbrances   relates  only  to  the  leasehold  interest  of  Company  or  its
subsidiary),  except for (a)  statutory  mechanics and  materialmen's  liens (b)
liens for current taxes not yet delinquent and (c) liens to secure  Indebtedness
created solely to finance the acquisition of the property subject  thereto,  the
existence of which,  are not reasonably  likely to result in a Company  Material
Adverse Effect.  All buildings,  structures and equipment owned or leased by the
Company or its  subsidiaries  are in  satisfactory  condition and repair for the
requirements of its business as now being conducted, except where the failure to
be in such  condition  and  repair  would  not have a Company  Material  Adverse
Effect.  There are no proceedings  affecting any of such  properties  pending or
threatened  which may reasonably be expected to curtail the use of such property
for the  purpose  for which it was  acquired  or the purpose for which it is now
used,  except where such  curtailment  would not have a Company Material Adverse
Effect.  Section 5.21 of the Company Disclosure Schedule lists all real property
owned or leased by the Company. The Company has delivered to Parent complete and
correct  copies of all leases of real or personal  property to which the Company
or any of its  subsidiaries  is a party and which  involve  payment by or to the
Company  or any of its  subsidiaries  in excess  of  $150,000  per any  12-month
period.

     Section 5.22 Environmental Liability.

          (a) The businesses of the Company and its  subsidiaries  have been and
are operated in material compliance with all applicable  statutory or regulatory
requirements of all Governmental Entities with jurisdiction over the environment
or over  workplace  health and  safety,  and  neither the Company nor any of its
subsidiaries has caused or allowed the


<PAGE>



generation,  treatment,  storage,  release or disposal of  hazardous  substances
except in accordance  with such statutes and  regulations as they existed at the
time of such generation, treatment, storage, release or disposal.

          (b) Neither the Company nor its  subsidiaries has received any written
notice or, to the best knowledge of the Company, any other  communication,  from
any  Governmental  Entity alleging or concerning any violation by the Company or
any of its subsidiaries of, or responsibility or liability of the Company or any
of  its  subsidiaries   under,  any  statute  or  regulation   relating  to  the
environment.  There are no pending  or, to the best  knowledge  of the  Company,
threatened,  claims,  suits,  proceedings or investigations  with respect to the
businesses or operations of the Company or any of its  subsidiaries  alleging or
concerning any violation of or responsibility or liability under any statutes or
regulations relating to the environment, nor does the Company have any knowledge
of any fact or condition which might reasonably be expected to give rise to such
a claim, suit, proceeding or investigation.

          (c) The Company and its subsidiaries are in possession of all material
approvals,  permits and licenses from all  Governmental  Entities under statutes
and regulations  relating to the environment and to workplace  health and safety
with  respect  to  the  operation  of the  businesses  of the  Company  and  its
subsidiaries;  there are no pending or, to the best  knowledge  of the  Company,
threatened,  actions,  proceedings or  investigations  seeking to revoke or deny
renewal of any of such  approvals,  permits and  licenses;  nor does the Company
have  knowledge of any fact or condition  which might  reasonably be expected to
give rise to any action,  proceeding or  investigation to revoke or deny renewal
of such  approvals,  permits or  licenses  if such  revocation  or denial  would
constitute a Company Material Adverse Effect.

     Section 5.23 Certain  Relationships.  All  billings  made to customers  and
suppliers  of the Company or any  subsidiary  have been  properly  computed  and
billed in compliance with applicable laws, rules, regulations,  agreements,  and
procedures,  and no such  customer  has any  right to any  refund,  price or fee
adjustments,  offsets, or similar right with respect to any such charges, except
where the  failure  to so comply or the  amount of such  right  would not have a
Company Material Adverse Effect.

     Section 5.24  Insurance.  Section 5.24 of the Company  Disclosure  Schedule
contains a complete list of all of the Company's current insurance  policies and
bonds and sets  forth for each such  policy  and bond the name of the  insurance
company,  the name of the  insured,  the name of any  additional  insureds,  the
amount and type of  coverage,  and, if greater than  $10,000,  the amount of the
deductible or retention, if any.

     Section 5.25 Certain Healthcare Regulatory Matters.

          (a) To the  best  knowledge  of  the  Company,  the  Company  and  its
subsidiaries  have not engaged  knowingly and willfully in any activities  which
are prohibited under federal Medicare and Medicaid statutes,  including, without
limitation,  42 U.S.C.  Section 1320a-7b and 42 U.S.C. Section 1395nn or related
state or local statutes or


<PAGE>



regulations or which otherwise constitutes fraud, including, without limitation,
the following:  (i) knowingly and willfully making or causing to be made a false
statement  or  representation  of a  material  fact in any  application  for any
benefit or payment;  (ii)  knowingly and willfully  making or causing to be made
any false statement or  representation of a material fact for use in determining
rights to any benefit or  payment;  (iii)  knowingly  and  willfully  failing to
disclose  knowledge  of the  occurrence  of any event  affecting  the initial or
continued right to any benefit or payment on its behalf or on behalf of another,
with intent to secure such benefit or payment  fraudulently;  (iv) knowingly and
willfully  soliciting or receiving  any  remuneration  (including  any kickback,
bribe, or rebate),  directly or indirectly,  overtly or covertly,  in cash or in
kind or  offering  to pay such  remuneration  (a) in  return  for  referring  an
individual to a person for the furnishing or arranging for the furnishing of any
item or service for which payment may be made in whole or in part by Medicare or
Medicaid or (b) in return for purchasing,  leasing, or ordering or arranging for
or recommending purchasing, leasing, or ordering any good, facility, service, or
item for which payment may be made in whole or in part by Medicare or Medicaid.

          (b)  The  Company  and  its  subsidiaries  have  complied  and  are in
compliance,  in all material  respects,  with  applicable  state laws regulating
pharmacies.

     with customers,  suppliers and others having business dealings with them to

          (d)  except as  disclosed  in the  Company  Disclosure  Schedule,  the
     Company shall not, nor shall it permit,  any of its subsidiaries to, except

     course of business  consistent with past practice),  (v) take any action to

     past practice,  or (vi) adopt, enter into, amend or terminate any contract,
     agreement,  commitment or arrangement to do any of the foregoing, provided,
     however,  that nothing contained herein shall prevent the Company or any of
     its subsidiaries from paying any bonus to or increasing the compensation of
     any employee in accordance  with the terms of any employment  agreement for
     such employee that was provided to Parent prior to the date hereof;



<PAGE>



          (e) the Company shall not, nor shall it permit any of its subsidiaries
     to, (i) make any investments in non-investment  grade securities  exceeding
     $1,000,000  or (ii)  sell,  at a loss of  greater  than  $50,000,  any debt
     securities held for investment purposes;

          (f) the Company shall not, nor shall it permit any of its subsidiaries
     to form any  corporation,  partnership,  joint  venture  or other  business
     association  or entity,  provided,  however,  that the  Company  may form a
     wholly owned  subsidiary  with the prior written  consent of Parent,  which
     consent shall not be unreasonably withheld; and

          (g) the Company shall not, nor shall it permit any of its subsidiaries
     to, take or cause to be taken any action, which would disqualify the Merger
     as a "pooling of interests" for accounting purposes.

     Section 7.2 Conduct of Business by Parent Pending the Merger.  Prior to the
Effective Date, unless the Company shall otherwise agree in writing or except as
otherwise required by this Merger Agreement:

          (a) Parent shall, and shall cause its Significant Subsidiaries to, use
     their  reasonable  best  efforts  to  preserve  their   relationships  with
     customers,  suppliers and others having business  dealings with them to the
     end that their goodwill and on-going  businesses shall be unimpaired at the
     Effective Date,  except such impairment as would not have a Parent Material
     Adverse Effect. Parent shall, and shall cause its Significant  Subsidiaries
     to use their reasonable best efforts to, (i) maintain  insurance  coverages
     and its books,  accounts  and records in the usual manner  consistent  with
     prior  practices;  (ii)  comply  in all  material  respects  with all laws,
     ordinances and  regulations of Governmental  Entities  applicable to Parent
     and its  Significant  Subsidiaries;  (iii) maintain and keep its properties
     and equipment in good repair,  working order and  condition,  ordinary wear
     and  tear  excepted;   and  (iv)  perform  in  all  material  respects  its
     obligations  under all contracts and  commitments to which it is a party or
     by which it is bound,  in each case  other  than  where the  failure  to so
     maintain, comply or perform, either individually or in the aggregate, would
     result in a Parent Material Adverse Effect;

          (b) Parent shall not amend any of the material  terms or provisions of
     the Parent Company Stock;

          (c) Parent  shall not take any action that would result in the failure
     to  maintain  the  trading  of Parent  Common  Stock on the New York  Stock
     Exchange;

          (d) Parent  shall not declare or pay any dividend or  distribution  on
     any outstanding shares of its capital stock; and



<PAGE>



          (e) Parent shall not, nor shall it permit any of its  subsidiaries to,
     take, or cause to be taken, any action which would disqualify the Merger as
     a "pooling of interests" for accounting purposes.

     Section 7.3 Conduct of Business of Sub.  During the period from the date of
this  Merger  Agreement  to the  Effective  Date,  Sub shall  not  engage in any
activities  of any nature except as provided in or  contemplated  by this Merger
Agreement.  Parent shall take all actions  necessary to cause Sub to perform its
obligations  under this Merger  Agreement  and to  consummate  the Merger on the
terms and conditions set forth herein.

     Section 7.4 Notice of Breach. Each party shall promptly give written notice
to the other party upon becoming  aware of the  occurrence or, to its knowledge,
impending or threatened occurrence, of any event which would cause or constitute
a breach of any of its  representations,  warranties  or covenants  contained or
referenced  in this  Merger  Agreement  and will use all  reasonable  efforts to
prevent or promptly remedy the same. Any such  notification  shall not be deemed

their  respective  subsidiaries  shall  afford to the  other and to the  other's

Statement and a preliminary  prospectus  with respect to the Parent Common Stock

Parent  and  the  Company  shall  use  all  reasonable   efforts  to  cause  the
Registration Statement to become effective as soon thereafter as practicable.

          (b)  Parent and the  Company  shall make all  necessary  filings  with
respect to the Merger and the Parent Share  Proposal,  under the  Securities Act
and the  Exchange  Act and the  rules  and  regulations  thereunder,  and  under
applicable  blue sky or  similar  securities  laws and shall use all  reasonable
efforts to obtain required approvals and clearances with respect thereto.

     Section 8.3  Compliance with the Securities Act.

          (a) Prior to the Effective Date, the Company shall deliver to Parent a
letter   identifying   all  persons  who  were,  at  the  time  of  the  Company
Shareholders'  Meeting convened in accordance with Section 3.6,  "affiliates" of
the Company as that term is used in paragraphs (c) and (d) of Rule 145 under the
Securities Act (the "Affiliates").  In identifying such Affiliates,  the Company
shall consult with counsel,  which counsel shall be  satisfactory to counsel for
Parent.

          (b) The Company shall obtain a written  agreement from each person who
is identified as an Affiliate in the letter  referred to in clause (a) above, in
the form  previously  approved by the parties,  that he or she will not offer to
sell, sell or otherwise  dispose of any Parent Common Stock issued to him or her
pursuant to the Merger,  except in compliance with Rule 145 or another exemption
from the  registration  requirements  of the  Securities  Act. The Company shall
deliver such written agreements to Parent on or prior to the Effective Date. The
Company  shall use its best efforts to cause each person who is identified as an
Affiliate  in such  opinion to deliver to Parent,  on or prior to the earlier of
(i) the mailing of the Proxy  Statement/Prospectus or (ii) the 30th day prior to
the  Effective  Date,  a written  agreement,  in the form to be  approved by the
parties hereto, that such Affiliate will not thereafter sell or in any other way
reduce such Affiliate's risk relative to any Parent Common Stock received in the
Merger (within the meaning of the Commission's  Financial  Reporting Release No.
l,  "Codification  of Financing  Reporting  Policies,"  Section  201.01 (47 F.R.
21030)  (April 15,  1982)),  until  such time as  financial  results  (including
combined  sales  and net  income)  covering  at  least  30  days of  post-merger
operations have been published, except as permitted by Staff Accounting Bulletin
No.  76  issued by the  Commission.  Within  45 days  after the end of the first
fiscal  quarter  of Parent  ending at least 30 days  after the  Effective  Date,
Parent will publish results including at least 30 days of combined operations of
Parent and the Company as referred to in the written agreements  provided for by

     Section 8.5 Employee Matters.

          (a) Subject to the  provisions of subsection  (b) of this Section 8.5,
Parent shall take all actions  necessary or  appropriate to permit the employees
of the Company and its subsidiaries on the Effective Date ("Affected Employees")
to participate  after the Effective Date in those of Parent's  employee  benefit
programs that are comparable to Company  employee  benefit programs and to cause
the Surviving  Corporation to take all actions necessary or appropriate to adopt
such Parent employee benefit programs effective as of the Effective Date. Parent
will cause the Surviving  Corporation to give each Affected Employee full credit
for service  with the Company for purposes of  eligibility  to  participate  in,
vesting  and  payment  of  benefits  under,  and  eligibility  for  any  Parent-
subsidized  benefit provided under (but not, except as provided in the preceding
clause for purposes of determining  the amount of any benefit  under),  any such
Parent employee benefit program.

          (b) After the Effective  Date,  Parent shall have a reasonable  period
not to  exceed  one year (the  "Review  Period")  in which to review  all of the
employee  and  fringe  benefit  plans  maintained  by the  Company or any of its
subsidiaries  (the  "Company  Plans") for  compatibility  and  consistency  with
Parent's  employee  benefit  programs.  During  the  Review  Period,  Parent may
determine to have the Surviving  Corporation  continue in effect any one or more
of the  Company  Plans,  amend or modify any one or more of the  Company  Plans,
merge one or more of the Company Plans into a comparable Parent employee benefit
plan adopted by the  Surviving  Corporation  or terminate any one or more of the
Company Plans in its or their  entirety.  Any such  amendment,  modification  or
termination shall not deprive any Affected Employee of any benefit in which such
Affected  Employee has become  entitled to  immediately  prior to the  Effective
Date.  If the Surviving  Corporation  is continuing in effect any of the Company
Plans  during  the  Review  Period,  then (i)  neither  it nor  Parent  shall be
obligated  to adopt a  comparable  Parent  employee  benefit  plan for  Affected
Employees,  it being  intended by the parties  that there be no  duplication  of
benefits,  and (ii) the obligation to have the Surviving  Corporation  adopt the
comparable Parent employee benefit plan or program, as set out in subsection (a)
above, shall arise, and such adoption shall be effective only as of the date the
comparable  Company Plan is  discontinued  and not as of the Effective  Date. If
Parent does not  maintain  an employee  benefit  plan  comparable  to one of the
Company  Plans,  there shall be no  obligation to adopt any plan or program upon
the discontinuance or termination of such Company Plan.

          (c) Parent  acknowledges  the existence and continuing  obligations of
HCS under the  collective  bargaining  agreements  listed on Section  5.9 of the
Company Disclosure Schedule. Notwithstanding the foregoing, nothing contained in
this Merger Agreement shall be construed under any  circumstances as imposing on
Parent or any of its subsidiaries  (other than HCS after the Effective Date) any
obligation or liability under such collective bargaining agreements.

     Section 8.6  Registration of Securities.  Parent promptly shall prepare and
file with the  Commission a  registration  statement  under the  Securities  Act
covering the shares of Parent Common Stock  issuable to  directors,  officers or
employees of the Company upon


<PAGE>



exercise of the  Outstanding  Options  pursuant to the provisions of Section 3.5
(the  "Employee  Shares  Registration  Statement").  Subsequent to the Effective
Date,  Parent will use all reasonable  efforts to (a) cause the Employee  Shares
Registration  Statement to become  effective  and (b) to the extent  required by
law, keep the Employee Shares Registration Statement current and effective under
the Securities Act.

     Section 8.7 Indemnification of Directors and Officers.

          (a) The  Certificate  of  Incorporation  of the Surviving  Corporation
shall contain the  provision  with respect to  indemnification  set forth in the
Certificate of Incorporation of the Company on the date of this Agreement, which
provisions shall not be amended,  repealed or otherwise modified for a period of
six years after the Effective Date in any manner that would adversely affect the
rights  thereunder of  individuals  who at the Effective  Date were directors or
officers of the Company in respect of actions or omissions occurring at or prior
to  the  Effective  Date  (including,   without  limitation,   the  transactions
contemplated by this Agreement), unless such modification is required by law.

          (b) From and after the Effective Date,  Parent shall,  and shall cause
the Surviving  Corporation to,  indemnify,  defend and hold harmless the present
and former officers and directors of the Company (collectively, the "Indemnified
Parties") against all losses, expenses, claims, damages,  liabilities or amounts
that are paid in  settlement  of, with the approval of Parent and the  Surviving
Corporation, or otherwise in connection with any claim, action, suit, proceeding
or  investigation  (a "Claim"),  based in whole or in part on the fact that such
person is or was a director or officer of the Company and arising out of actions
or omissions  occurring at or prior to the Effective  Date  (including,  without
limitation,  the transactions  contemplated by this Agreement),  in each case to
the full extent  permitted  under the DGCL (and shall pay expenses in advance of
the final disposition of any such action or proceeding to each Indemnified Party
to the fullest extent  permitted  under DGCL,  upon receipt from the Indemnified
Party to whom  expenses are advanced of the  undertaking  to repay such advances
contemplated by Section 145(e) of the DGCL).

          (c) Any Indemnified Party wishing to claim  indemnification under this
Section 8.7, upon learning of any such Claim,  shall notify Parent (although the
failure so to notify Parent shall not relieve  Parent from any  liability  which
Parent may have  under  this  Section  8.7  except to the  extent  such  failure
prejudices Parent), and shall deliver to Parent the undertaking  contemplated by
Section 145(e) of the DGCL.

          (d)  Parent  shall  use its  reasonable  best  efforts  to cause to be
maintained 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  prior to the  Effective  Date;
provided,   however,  that  (i)  Parent  may  substitute  therefor  policies  of
substantially  similar  coverage  containing  substantially  similar  terms  and
conditions for the Indemnified  Parties to the extent  reasonably  available and
(ii) Parent shall not be required to pay an annual premium for such insurance in
excess of 150% of the last annual premium paid


<PAGE>



prior to the date hereof,  but in such case shall  purchase as much  coverage as
possible for such amount.

          (e) This  Section  8.7 is intended to be for the benefit of, and shall
be  enforceable   by,  the  Indemnified   Parties,   their  heirs  and  personal
representatives and shall be binding on Parent and the Surviving Corporation and
their respective successors and assigns.

     Section  8.8 HSR Act.  The  Company  and  Parent  shall use all  reasonable
efforts  to  file  as soon as  practicable  notifications  under  the HSR Act in
connection  with the  Merger  and the  transactions  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 8.9 Further Assurances.  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 Merger
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 or other legal bar
to the Merger (and, in such case, to proceed with the Merger as expeditiously as
possible),  subject, however, in the case of the Merger Agreement and the Parent
Share Proposal,  to the appropriate  vote of the shareholders of the Company and
Parent.  Notwithstanding the foregoing,  there shall be no action required to be
taken and no action will be taken in order to consummate  and make effective the
transactions  contemplated by this Merger Agreement if such action, either alone
or together  with another  action,  would result in a Company  Material  Adverse
Effect or a Parent Material Adverse Effect.

     Section 8.10 No Solicitation.  Subject to the fiduciary duties of the Board
of Directors of the Company, as advised by outside counsel,  neither the Company
nor any of its subsidiaries shall,  directly or indirectly,  take (nor shall the
Company authorize or permit its subsidiaries,  officers,  directors,  employees,
representatives,  investment bankers, attorneys,  accountants or other agents or
affiliates,  to take) any  action to (a)  encourage,  solicit  or  initiate  the
submission of any Acquisition  Proposal (as defined  below),  (b) enter into any
agreement with respect to any Acquisition Proposal or (c) participate in any way
in discussions or  negotiations  with, or furnish any information to, any person
in connection  with, or take any other action to facilitate any inquiries or the
making of any proposal that  constitutes,  or may reasonably be expected to lead
to, any Acquisition  Proposal.  The Company will promptly  communicate to Parent
any  solicitation  by the  Company  and the terms of any  proposal  or  inquiry,
including the identity of the person and its affiliates making the same, that it
may  receive  in  respect of any such  transaction,  or of any such  information
requested from it or of


<PAGE>



any such  negotiations or discussions  being sought to be initiated with it. For
purposes  of this  Merger  Agreement,  "Acquisition  Proposal"  shall  mean  any
proposed (i) merger, consolidation or similar transaction involving the Company,
(ii)  sale,  lease  or other  disposition  directly  or  indirectly  by  merger,
consolidation,  share  exchange  or  otherwise  of assets of the  Company or its
subsidiaries  representing 25% or more of the consolidated assets of the Company
and its subsidiaries,  (iii) issue,  sale, or other disposition of (including by
way  of  merger,  consolidation,  share  exchange  or any  similar  transaction)
securities  (or  options,   rights  or  warrants  to  purchase,   or  securities
convertible into, such securities)  representing 25% or more of the voting power
of the Company or (iv) transaction in which any person shall acquire  beneficial
ownership (as such term is defined in Rule 13d-3 under the Exchange Act), or the
right to acquire  beneficial  ownership  or any "group" (as such term is defined
under the Exchange  Act) shall have been formed which  beneficially  owns or has
the right to  acquire  beneficial  ownership  of 25% or more of the  outstanding
Company Common Stock.

Agreement  are for  reference  purposes only and shall not affect in any way the
meaning or interpretation of this Merger Agreement.

          (b) For purposes of this Agreement the  promulgation of proposals for,
or the  implementation  of, federal or state health care  legislation  shall not
constitute either a Parent Material Adverse Effect or a Company Material Adverse
Effect.

          (d) Notwithstanding any other provision of the Agreement, it shall not

                              CONSULTING AGREEMENT

                  CONSULTING  AGREEMENT  dated as of  March  27,  1995,  between
Diagnostek,  Inc., a Delaware  corporation  (the  "Corporation"),  Value Health,
Inc., a Delaware  corporation  ("Parent") (for purposes of Section 6 hereof) and
Nunzio P. DeSantis (the "Consultant");

                  WHEREAS, pursuant to the Agreement and Plan of Merger dated as
of the date hereof (the "Merger Agreement"),  VHI Merger- Sub. Corp., a Delaware
corporation  and  a  wholly-owned   subsidiary  of  Parent,   will,  subject  to
satisfaction of certain conditions, be merged with and into the Corporation with
the result that the Corporation will become a wholly-owned  subsidiary of Parent
(such merger being referred to herein as the "Merger"); and

                  WHEREAS, effective as of the Effective Date (as defined in the
Merger Agreement),  the employment of Consultant by the Corporation  pursuant to
the Employment Agreement dated as of October 1, 1990 between the Corporation and
the  Consultant  (the  "Employment   Agreement")  shall  be  terminated  by  the
Corporation; Consultant will thereupon be entitled to and shall receive from the
Corporation  the  "Termination  Compensation"  specified  in Section 5(c) of the
Employment Agreement;  and neither the Consultant nor the Corporation shall have
any further  obligations  thereunder relating to the employment of Consultant by
the Corporation or any of its subsidiaries; and

                  WHEREAS,  the  Corporation   recognizes  that  the  Consultant
possesses  unique  and  extensive  skill  and  expertise  with  respect  to  the
businesses  in which the  Corporation  is  engaged  and with  respect to current
trends and developments in the healthcare industry generally; and

                  WHEREAS, the Corporation desires to retain the services of the
Consultant  as a  consultant  in order that his  personal  knowledge,  skill and
experience  be  available  to assist the  Corporation  and its  affiliates  with
respect to specified aspects of their operations and strategic planning, and the
Consultant  is willing to perform in such  capacity on the terms and  conditions
hereinafter set forth;

                  NOW,  THEREFORE,  in  consideration  of the premises and other
mutual covenants and agreements herein contained,  the parties hereto, intending
to be legally bound, hereby mutually covenant and agree as follows:


<PAGE>




                  1. Consultant's Duties and Responsibilities.

                  (a) Effective as of the Effective Date, the Corporation hereby
retains the  Consultant as a consultant for the Term (as  hereinafter  defined).
The  Consultant  agrees to act in such  capacity  on the  terms  and  conditions
hereinafter  set forth.  The  Consultant's  services  shall consist of providing
advice to the  Corporation  or any of its  affiliates  with respect to specified
aspects  of their  operations  and  strategic  planning,  to the  extent  and as
instructed  from  time to time by the  Chairman  of the  Board or  President  of
Parent.  Initial duties are expected to include assistance in integration of the
Corporation  within the Parent  organization,  maintenance of the  Corporation's
customer  relationships and assistance to Parent in exploration of opportunities
for the imaging  business of the Corporation.  In performing such services,  the
Consultant shall use all reasonable efforts to promote the best interests of the
Corporation. For purposes of this Agreement, the term "affiliates" shall include
all entities  controlled by or under common  control with the  Corporation.  The
Consultant shall perform his services in Albuquerque, New Mexico.

                  (b) In performing  his services,  the  Consultant is not to be
considered an officer or employee of the  Corporation or any of its  affiliates,
and he will not be eligible to  participate in any profit  sharing,  retirement,
life  insurance,  health  insurance  or any  other  benefit  plan  available  to
employees  of the  Corporation  or any of its  affiliates,  except to the extent
otherwise  provided in Section 3(c) hereof.  The Consultant agrees that he shall
not  represent  himself  as  acting  in  his  capacity  as a  consultant  to the
Corporation (or any affiliate  thereof),  or otherwise use his affiliation  with
the  Corporation  (or any affiliate  thereof),  in his business  activities  not
conducted  pursuant  to this  Agreement  on  behalf of the  Corporation  (or any
affiliate  thereof).  In the  performance  of  Consultant's  services under this
Agreement,  Consultant  shall  adhere  to  those  fiduciary  standards,  ethical
practices,  and standards of care and competence  which are normal and customary
for  professionals  rendering  consulting  and  advisory  services of the nature
provided for in this Agreement.  Consultant is not authorized to waive any right
or to incur,  enter into, assume, or create any debt,  obligation,  agreement or
release of any kind  whatsoever  in the name of or on behalf of the  Corporation
(or  any  affiliate  thereof)  or in any  way to bind  the  Corporation  (or any
affiliate thereof).

                  (c) For a period of six months from the  Effective  Date,  the
Corporation shall provide  Consultant with suitable office and secretarial space
and  equipment  at the  Corporation's  offices  in  Albuquerque,  New Mexico and
support to enable Consultant to assist the Corporation in the


<PAGE>



transition of management of the Corporation following the Merger.

                  2. Term.

                  (a) The term of this  Agreement  (the "Term") will commence on
the  Effective  Date and will  continue  through  the fifth  anniversary  of the
Effective  Date  subject to earlier  termination  pursuant  to the terms of this
Agreement.  This Agreement  (except for the  obligations set forth in Section 7)
shall terminate  immediately in the event of the Consultant's death,  disability
or resignation;  provided that, in the event of disability of Consultant,  until
the earlier of the death of Consultant or the fifth anniversary of the Effective
Date, the Corporation shall continue to comply with Section 3(b) hereof.

                  (b) In the event this Agreement is terminated by reason of the
death or  disability  of the  Consultant,  the  Corporation  shall  continue the
payment of the fee  described  in Section  3(a) hereof for a period of 12 months
thereafter (but not beyond the original five-year term) to the Consultant or his
personal  representatives (in the case of disability) or to the surviving spouse
of the Consultant or, if none, to the  Consultant's  estate,  in the case of the
Consultant's death. For purposes of this Agreement,  "disability" shall mean the
Consultant's  inability or incapacity  to perform his duties  hereunder due to a
mental or physical illness,  accident,  injury or condition, or any other cause,
for a period of 180 days in any twelve consecutive month period.

                  (c)  Notwithstanding   anything  in  this  Agreement,   it  is
expressly  understood  and agreed by all parties  hereto that,  in the event the
Merger Agreement is terminated for any reason  whatsoever,  this Agreement shall
be null and void, ab initio,  without any liability on the part of any party (or
any of such party's affiliates) to any other party.

                  3. Consulting  Fees. In  consideration  for the services to be
rendered under this Agreement,  the Consultant shall,  during the Term,  receive
the following:

                    (a)  Fee.  A fee of  $120,000  per  year  (payable  in equal
          monthly installments on the 15th day of each month).

                    (b) Split Dollar  Agreement.  The Corporation  will pay when
          due the  portion of the  premiums  for life  insurance  policies  (the
          "Policies")  required to be paid pursuant to a Split Dollar Agreement,
          dated as of April 1, 1992,  by and  between  the  Corporation  and the
          DeSantis Family Irrevocable Trust, a Split Dollar Agreement,  dated as
          of April 1, 1992, by and between the Corporation and


<PAGE>



          the Dorothy  Smith  Irrevocable  Trust and a Split  Dollar  Agreement,
          dated as of April 1, 1992,  by and  between  the  Corporation  and the
          Velia DeSantis Family Trust (together,  the "Split Dollar Agreements")
          which are due within the Term (provided that,  without  increasing the
          foregoing obligation, the annual aggregate premiums payable thereunder
          shall not exceed $327,000). The Consultant agrees that the Corporation
          may assign its rights and interest in the Split Dollar  Agreements  to
          Parent or any affiliate  thereof and that the  Corporation  and/or any
          such assignee shall have a perfected first priority  secured  interest
          in the  Policies  for,  and  shall  have a right to  receive  from the
          proceeds of such  Policies,  the full  amount of any premium  payments
          with  respect to such  Policies  made by the  Corporation  or any such
          affiliate or their  predecessors,  and the Consultant  agrees to amend
          the Split Dollar Agreements to the extent reasonably  requested by the
          Corporation  to  provide   therefor,   and  further  agrees  that  the
          Corporation  shall have no obligation to make any payments  under this
          Section  3(b) at any  time at which  the  Corporation  has  reasonably
          determined, after giving Consultant notice and a 30-day opportunity to
          cure,  that  the  Corporation  does not have  such a  perfected  first
          priority   secured   interest.   Without   limiting  in  any  way  the
          Corporation's  rights hereunder and under the Split Dollar Agreements,
          the  Corporation's  obligations  under this  Section 3(b) shall cease,
          prior  to the  expiration  of  the  Term,  upon  the  first  to die of
          Consultant or  Consultant's  spouse if, but only if, the proceeds from
          the policies covered by the Split Dollar  Agreements which are paid to
          beneficiaries  (other than the  Corporation or any of its  affiliates)
          upon such first death are  sufficient  to pay or otherwise  adequately
          provide  for  all  future  premiums  estimated  to be  due  under  the
          remaining policies covered by the Split Dollar Agreements.  Subject to
          the foregoing  provisions of this Section 3(b), the payments  required
          by the  Corporation  in this Section 3(b) shall continue for the Term,
          but for not less than five years;  provided that the Corporation shall
          have no obligation to make any further payments hereunder in the event
          of an  uncured  material  breach  by  Consultant  of the Non-  Compete
          Agreement (as defined in Section 4(i) hereof).

                    (c)  Health  Insurance.  If  and  to  the  extent  that  the
          Corporation's  existing  group health  benefits  providers  confirm in
          writing prior to the Effective Date that Consultant's  engagement as a
          consultant  under this Agreement will enable  Consultant (and eligible
          family  members)  to continue  to be covered  under the  Corporation's
          group health  benefit plan or plans at normal group rates as in effect
          from time to time, then


<PAGE>



          the Corporation will take reasonable steps to facilitate the obtaining
          and  maintaining  of such  coverage  during  the Term  subject  to its
          continued  availability.  No  assurance  has or will be  given  by the
          Corporation with respect to the availability of this coverage. If such
          coverage is available,  the  Corporation  will pay that portion of the
          premiums for such coverage  which it currently pays for Consultant and
          his eligible family members.

                  4.  Termination.   The  Corporation  may  only  terminate  the
consulting  engagement  set forth in this  Agreement for cause.  For purposes of
this Agreement, the term "cause" shall mean any of the following:

                    (i) Any material  breach by the  Consultant of any provision
               of this Agreement or the Agreement Not to Compete  between Parent
               and   Consultant   of  even  date  herewith  (the  "Non-  Compete
               Agreement"),  which breach  continues  for 45 days after  written
               notice to the Consultant specifying the breach.

                    (ii) Any  willful  action by the  Consultant  (other than an
               action taken at the direction of the Corporation) that

                         (A) is intended to have; or

                         (B) could have reasonably been expected to have,

               a  materially   detrimental   effect  on  the  interests  of  the
               Corporation or any of its affiliates; or

                    (iii)  Any  final  and   unappealable   conviction   of  the
               Consultant  of any offense  involving  (A) moral  turpitude,  (B)
               misappropriation of funds or (C) drug addiction.

                  Upon  termination of this Agreement for cause,  the Consultant
shall  forfeit  any  unvested  portion of the  Option  (as  defined in Section 6
hereof) and any right to  additional  fees  (except for accrued but unpaid fees)
under this Agreement or the Non-Compete  Agreement,  and the  Corporation  shall
have no further  obligation to the  Consultant  hereunder with respect hereto or
thereto (except as otherwise provided in Section 3(b) hereof).

                  5. Status as  Independent  Contractor.  It is mutually  agreed
that the  Consultant  is an  independent  contractor  and not an employee of the
Corporation  and as such, the Consultant  shall be responsible for the following
throughout the entire Term of this Agreement.


<PAGE>





                  (a) Maintaining his own records of expenses;

                  (b) Paying self-employment taxes, income taxes and other taxes
          and assessments for which Consultant has responsibility; and

                  (c) Complying with all relevant local,  state and federal laws
          applicable to Consultant in the context of this Agreement.

                  6.  Stock Option; Guaranty.

                  (a) In further  consideration  of the valuable  and  extensive
services to be rendered by Consultant  hereunder,  effective as of the Effective
Date,  the  Consultant  shall be granted an option  (the  "Option")  to purchase
350,000 shares of common stock, no par value per share, of Parent at an exercise
price per share equal to the closing  price of the common stock of Parent on the
New York  Stock  Exchange  on the date on which the Merger is  consummated.  The
Option  shall be  subject to terms and  conditions  set forth in the form of the
Stock Option Agreement annexed hereto as Annex I.

                  (b) Parent hereby  guarantees  all of the  obligations  of the
Corporation under this Agreement.

                  7. Indemnification.

                  The  parties  hereto  agree,   and  this  Agreement  has  been
negotiated  based  on  the  mutual  belief,  that  all  amounts  payable  to the
Consultant hereunder and under the Non-Compete  Agreement,  severally and in the
aggregate,  constitute "reasonable compensation" for the personal services to be
rendered (or, in the case of the  Non-Compete  Agreement,  not rendered to third
parties) by the  Consultant,  within the meaning of Section 280G of the Internal
Revenue  Code  of  1986,  as  amended  (the  "Code").  If,  notwithstanding  the
foregoing,  there is a final  determination  that  any  portion  of the  amounts
payable to or for the  benefit of the  Consultant  under this  Agreement  and/or
under the  Employment  Agreement or the  Non-Compete  Agreement  constitutes  an
"excess parachute  payment" as such term is used in Section 280G and 4999 of the
Code, then the Corporation  shall,  within 60 days of said final  determination,
pay to the Consultant an additional sum (the  "Additional  Amount") in an amount
such that after all federal, state and local taxes of any kind which would apply
to the receipt by the Consultant of the Additional  Amount have been  subtracted
therefrom, the remainder of the Additional Amount would equal the sum of (i) the
amount of the tax imposed on the  Consultant by Section  4999(a) of the Code and
by any comparable provision of any state or local tax law with


<PAGE>



respect  to the  "excess  parachute  payment",  plus  (ii) any  interest  and/or
penalties thereon.

                  The Corporation shall have the right, at its sole expense,  to
contest an assertion by any taxing  authority that any of the aforesaid  amounts
payable to the Consultant  constitutes an "excess parachute payment" and, if the
Corporation  chooses to contest any such  assertion,  the  Consultant  agrees to
cooperate with and assist the  Corporation in such context.  If, the Corporation
elects not to contest such assertion,  there shall be no obligation hereunder on
the part of the  Consultant  to contest  such  assertion.  For  purposes of this
Agreement,  a "final  determination" shall mean a court decision or an assertion
or  determination by a taxing authority from which the Corporation (on behalf of
Consultant) is unable to appeal further (or from which any further  appeals have
been rejected or refused); or which the Corporation  determines not to appeal or
contest  further;  or an assertion or  determination by a taxing authority which
the Corporation  elects not to contest;  or the settlement of any such assertion
or  determination  to  which  the  Corporation  agrees.  The  obligation  of the
Corporation  to the  Consultant  set forth in this  Section 7 shall  survive the
expiration or other  termination of this  Agreement,  the  Employment  Agreement
and/or the  Non-Compete  Agreement,  any  provision  of this  Agreement or those
Agreements to the contrary notwithstanding.

                  Consultant agrees to notify the Corporation in a timely manner
in the event of any audit or other  proceeding by any taxing  authority in which
it is asserted that any portion of the amounts  payable to or for the benefit of
Consultant  under this  Agreement,  the Employment  Agreement or the Non-Compete
Agreement  constitutes an "excess parachute payment".  Consultant further agrees
not to settle  any such  assertion  without  the prior  written  consent  of the
Corporation.

                  8.  Notice.  Any notice that either party hereto may desire to
give the other shall be deemed delivered three days after the date on which such
Notice has been  deposited in the United  States Mail as certified or registered
mail, return receipt requested, addressed as follows:

                    To the Corporation:

hereto by giving notice thereof to the other pursuant to this paragraph.  Notice
may also be given by facsimile to the  foregoing  facsimile  numbers or personal
delivery at the  foregoing  addresses,  and delivery of any such notice shall be
deemed made at the time of the  sending of a  facsimile  or upon the making of a
personal delivery.

                  9. No Conflict.  Consultant represents and warrants that he is
not a party to any agreement or under any  obligation  which would conflict with
the  terms  of  this   Agreement   or  prevent   him  from   carrying   out  his
responsibilities under this Agreement.

                  10.  Waiver/Miscellaneous.  No waiver of any provision of this
Agreement  shall be effective  unless in a writing  signed by the waiving party.
The  Corporation  shall be permitted  to withhold  any amounts  which any taxing
authority asserts are required by law to be withheld for federal, state or local
tax  purposes  (the  withholding  of which  shall be treated as a payment to the
Consultant for purposes of this Agreement), and the Consultant shall upon notice
and request  reimburse  the  Corporation  for any amounts not withheld that were
required to be withheld.

                  11. Assignment;  Binding Effect. The obligations of Consultant
hereunder  are  personal  and may not be assigned or  delegated by him under any
circumstances.  This Agreement shall be binding upon and inure to the benefit of
the  parities  hereto and their  respective  heirs (to the extent  provided  for
herein), successors and permitted assigns.

                  12.  Headings.  The  paragraph  and  other  headings  in  this
Agreement are inserted  solely as a matter of convenience  and for reference and
are not a part of this Agreement.

                  13.  Severability.  If the final  determination  of a court of
competent jurisdiction  declares,  after the expiration of the time within which
judicial review (if permitted) of such determination may be perfected,  that any
term or provisions  hereof is invalid or  unenforceable  (a) the remaining terms
and provisions  hereof shall be unimpaired and (b) the invalid or  unenforceable
term or provision  shall be deemed replaced by a term or provision that is valid
and


<PAGE>



enforceable and that comes closest to expressing the intention of the invalid or
unenforceable term or provision.

                  14.  Governing  Law. This  Agreement  shall be governed by and
construed in  accordance  with the laws of the State of Delaware  applicable  to
contracts  to be  performed  in that state and without  regard to law that might
otherwise govern under applicable principles of conflict of laws.

                  15.  Counterparts.  This  Agreement  may be executed in two or
more counterparts,  each of which shall be deemed an original,  but all of which
together shall constitute one and the same instrument.

                  16. Entire Agreement/Modification. The terms and provisions of
this instrument constitute the entire agreement between the parties with respect
to the subject  matter hereof and shall  supersede all previous  communications,
representations  or  agreements,  either  oral or  written,  between the parties
hereto with respect to the subject  matter  hereof.  This  Agreement  may not be
amended, modified or altered except in writing signed by the parties.

                  17.  Expenses.  The Corporation  will reimburse the Consultant
for  reasonable  out-of-pocket  expenses  incurred by Consultant  outside of New
Mexico  which are  incurred  in the  performance  of his  duties  hereunder,  in
accordance with Parent's corporate  policies and subject to reasonably  detailed
documentation.

                  18.  Release.  In  consideration  of the payments and benefits
provided to the  Consultant  under this  Consulting  Agreement,  the  Consultant
hereby  releases  and  forever  discharges  the  Corporation,  Parent  and their
respective  affiliates,  and each of their  respective  officers,  employees and
directors  from any and all  claims,  actions  and  causes  of  action  that the
Consultant may have, or in the future may possess, arising out of his employment
relationship  with the  Corporation or any of its affiliates and the termination
thereof.  The  provisions of this Section 18 shall not apply with respect to (i)
the  obligations  of  the  Corporation   hereunder  and  under  the  Non-Compete
Agreement,  (ii) claims for payment of  currently  accrued  compensation,  (iii)
rights to indemnification in the Consultant's capacity as an officer or director
of the  Corporation or any of its  subsidiaries,  (iv) any benefits to which the
Consultant is entitled under terms of employee  benefit plans of the Corporation

                              VALUE HEALTH, INC.

                     Non-Qualified Stock Option Agreement

                  Value Health,  Inc., a Delaware  corporation  (the "Company"),
hereby  grants  this  ___  day  of  _________,  1995,   (the  "Grant  Date")  to
___________________  (the "Optionee") an option to purchase a maximum of 350,000
shares of its Common Stock, no par value (the "Option Shares"),  at the price of
$_________ per share, on the following terms and conditions:

                  1. Grant Under 1991 Stock Option Plan;  Consulting  Agreement.
This option is granted  pursuant to and is governed by the Company's  1991 Stock
Option Plan (the "Plan") and, unless the context otherwise requires,  terms used
herein  shall  have the same  meanings  as in the Plan.  Determinations  made in
connection  with this option  pursuant to the Plan shall be governed by the Plan
as it exists on this date. Optionee has entered into a Consulting Agreement (the
"Consulting  Agreement") with Diagnostek,  Inc. (the "Corporation") of even date
herewith  pursuant to which  Optionee has been retained by the  Corporation as a
consultant.

                  2. Grant as Non-Qualified Option. This option shall be treated
for  federal  income tax  purposes as a  Non-Qualified  Option  (rather  than an
incentive  stock  option),  and the Board of Directors  of the  Company,  or any
committee  approved  by the  Board,  intends  to  take  appropriate  action,  if
necessary, to achieve this result.

                  3. Vesting.  If the Optionee has  continued to be engaged as a
consultant under the  Consulting Agreement on  the following dates, the Optionee
may exercise  this option  for the number of shares set opposite  the applicable
date:

                  On January 2, 1996          -        70,000 shares

                  On January 2, 1997          -        70,000 shares

                  On January 2, 1998          -        70,000 shares

                  On January 2, 1999          -        70,000 shares

                  On January 2, 2000          -        70,000 shares

Except as otherwise  provided in Articles 4 and 5, the  foregoing  rights may be
exercised  up to and  including  the date  which is ten (10) years from the date
this option is granted.


<PAGE>



                  4. Termination of Consulting  Agreement.  If the engagement of
Optionee as a consultant  under the  Consulting  Agreement is  terminated by the
resignation  of  Optionee  prior  to the  end of the  Term  (as  defined  in the
Consulting  Agreement)  or by the  Corporation  for  cause  (as  defined  in the
Consulting  Agreement),  no further  installments  of this option  shall  become
exercisable  and this option  shall  terminate  after the passage of ninety (90)
days from the date of such termination, but in no event later than the scheduled
expiration  date. In such case, the Optionee's  only rights  hereunder  shall be
those which are properly exercised before the termination of this option.

                  5. Death; Disability.  If the Optionee dies while engaged as a
consultant under the Consulting Agreement,  this option may be exercised, to the
extent of the number of shares  with  respect to which the  Optionee  could have
exercised it on the date of his death, by his estate, personal representative or
beneficiary to whom this option has been assigned  pursuant to Article 9 hereof,
at any time  within  180 days  after the date of death,  but not later  than the
scheduled  expiration  date. If the Optionee's  engagement as a consultant under
the  Consulting  Agreement is terminated by reason of his disability (as defined
in the Consulting Agreement), this option may be exercised, to the extent of the
number of shares with respect to which the Optionee  could have  exercised it on
the date of such termination, at any time within 180 days after the date of such
termination, but not later than the scheduled expiration date. At the expiration
of such  180-day  period or the  scheduled  expiration  date,  whichever  is the
earlier,  this option shall  terminate  and the only rights  hereunder  shall be
those as to which the option was properly exercised before such termination.

                  6. Partial Exercise.  Exercise of this option up to the extent
above  stated  may be made in part at any time and from time to time  within the
above  limits,  except that this option may not be exercised for a fraction of a
share  unless such  exercise is with respect to the final  installment  of stock
subject to this option and a fractional  share (or cash in lieu thereof) must be
issued to permit the Optionee to exercise completely such final installment. Any
fractional  share with respect to which an  installment of this option cannot be
exercised  because of the limitation  contained in the preceding  sentence shall
remain  subject to this option and shall be available for later  purchase by the
Optionee in accordance with the terms hereof.

                  7. Payment of Price.  The option  price  is  payable in United
States dollars and may be paid in cash or by check, or any combination of the
foregoing, equal in amount to the option price.



<PAGE>



                  8.  Method  of  Exercising  Option.  Subject  to the terms and
conditions of this Agreement,  this option may be exercised by written notice to
the Company, at the principal executive office of the Company. Such notice shall
state the  election to exercise  this option and the number of shares in respect
of which it is being  exercised  and shall be signed by the person or persons so
exercising this option.  Such notice shall be accompanied by payment of the full
purchase  price of such  shares,  and the  Company or its  transfer  agent shall
deliver  a  certificate  or  certificates  representing  such  shares as soon as
practicable after the notice shall be received.  The certificate or certificates
for the shares as to which this  option  shall have been so  exercised  shall be
registered in the name of the person or persons so  exercising  this option (or,
if this option shall be  exercised by the Optionee and if the Optionee  shall so
request in the notice exercising this option, shall be registered in the name of
the Optionee and another person jointly,  with right or survivorship)  and shall
be  delivered  as provided  above to or upon the written  order of the person or
persons  exercising  this option.  In the event this option shall be  exercised,
pursuant to Article 5 hereof,  by any person or persons other than the Optionee,
such  notice  shall be  accompanied  by  appropriate  proof of the right of such
person or persons to exercise  this  option.  All shares that shall be purchased
upon the  exercise  of this option as  provided  herein  shall be fully paid and
non-assessable.

                  9. Option Not Transferable. This option is not transferable or
assignable except by will or by the laws of descent and distribution. During the
Optionee's lifetime, only the Optionee can exercise this option.

                  10. No Obligation to Exercise Option. The grant and acceptance
of this option impose no obligation on the Optionee to exercise it.

                  11.  Right  to  Terminate  Services  as  a  Consultant.   This
Agreement does not constitute a contract of, or an implied  promise to continue,
Optionee's  status  as a  consultant  to the  Corporation  or to be  engaged  or
retained  in any status or  position  by or with the Company or any of its other
affiliated  entities;  nor does this Agreement  affect any right the Corporation
may have to terminate  Optionee's  consulting  engagement at any time.  Optionee
shall  have no rights in the  benefits  conferred  by this  Agreement  or in any
Option  Shares  except to the extent the Option is  exercised  while  vested and
otherwise  in  accordance  with the  terms of this  Agreement.  Nothing  in this
Section  11 shall  alter  the  rights  and  obligations  of the  parties  to the
Consulting Agreement.


<PAGE>



                  12. No Rights as  Stockholder  until  Exercise.  The  Optionee
shall have no rights as a  stockholder  with  respect to shares  subject to this
Agreement until a stock certificate therefor has been issued to the Optionee and
is fully paid for.  Except as is expressly  provided in the Plan with respect to
certain changes in the  capitalization  of the Company,  no adjustment  shall be
made for  dividends or similar  rights for which the record date is prior to the
date such stock certificate is issued.

                  13.  Capital  Changes  and  Business  Successions.  It is  the
purpose of this option to encourage the Optionee to work for the best  interests
of the Company and its stockholders.  Since, for example, that might require the
issuance of a stock dividend or a merger with another  corporation,  the purpose
of this option would not be served if such a stock  dividend,  merger or similar
occurrence  would  cause  the  Optionee's  rights  hereunder  to be  diluted  or
terminated  and thus be contrary to the Optionee's  interest.  The Plan contains
provisions   designed  to  preserve  options  at  full  value  in  a  number  of
contingencies.  Therefore, provisions in the Plan for adjustment with respect to
stock subject to options and the related  provisions  with respect to successors
to the  business of the Company are hereby  made  applicable  hereunder  and are
incorporated herein by reference.

                  14.  Withholding  Taxes.  The Company  shall be  permitted  to
withhold any amounts which any taxing  authority  asserts are required by law to
be withheld  for  federal,  state or local tax  purposes  upon  exercise of this
option,  and the Optionee shall, upon notice and request,  reimburse the Company
for any amounts not withheld that were required to be withheld.

                  15.  Governing  Law. This  Agreement  shall be governed by and
interpreted in accordance with the internal laws of the State of Delaware.

                  IN WITNESS  WHEREOF,  the Company and the Optionee have caused

                         AGREEMENT NOT TO COMPETE

                  AGREEMENT NOT TO COMPETE  dated as of March 27, 1995,  between
Value Health,  Inc., a Delaware  corporation (the "Corporation") and Diagnostek,
Inc., a Delaware  corporation  (the  "Acquired  Company") and Nunzio P. DeSantis
("DeSantis");

                  WHEREAS, pursuant to the Agreement and Plan of Merger dated as
of the date hereof (the "Merger  Agreement"),  Value Health  Merger-Sub Corp., a
Delaware  corporation and a wholly-owned  subsidiary of the  Corporation,  will,
subject to  satisfaction  of  certain  conditions,  be merged  with and into the
Acquired   Company  with  the  result  that  Acquired   Company  will  become  a
wholly-owned subsidiary of the Corporation (such merger being referred to herein
as the "Merger"); and

                  WHEREAS, effective as of the Effective Date (as defined in the
Merger  Agreement),  the employment of DeSantis by the Acquired Company pursuant
to the Employment Agreement dated as of October 1, 1990 between Acquired Company
and DeSantis shall be terminated by the Acquired Company; and

                  WHEREAS,  the  Corporation  has requested  that DeSantis enter
into a consulting agreement (the "Consulting Agreement") so that the Corporation
can avail  itself  of  DeSantis'  unique  skills  and  expertise  and  extensive
experience  with respect to those  businesses in which the  Corporation  and the
Acquired  Company are presently  engaged,  and DeSantis has agreed to enter into
the Consulting Agreement on the terms and conditions set forth therein; and

                  WHEREAS, in the course of developing his skills, expertise and
experience,  DeSantis has  established  valuable  relationships  with suppliers,
customers  and  agencies  throughout  the  United  States in  healthcare-related
fields; and

                  WHEREAS,   the  Corporation  and  the  Acquired  Company  have
determined  that it is imperative in order to protect the value and the benefits
which they  anticipate  will accrue to them by virtue of the  Merger,  to secure
DeSantis' agreement, inter alia, to refrain from competing with the Corporation,
the Acquired Company and their affiliates for a period of time considered by the
parties hereto to be sufficient to protect the interests of the Corporation, the
Acquired  Company and their  affiliates,  and DeSantis is willing to extend such
protection to the  Corporation  and the Acquired  Company,  all on the terms and
conditions hereinafter set forth;

                  NOW,  THEREFORE,  in  consideration  of the premises and other
mutual covenants and agreements herein contained,  the parties hereto, intending
to be legally bound hereby, mutually covenant and agree as follows:

                  1.   0bligations  of  and   Restrictions  and  Limitations  on
DeSantis.

                           (a) No Competing  Employment  or Service.  During the

                  recent l2- month  period,  a customer  or client of any of the
                  Companies.

                           (c)   Confidential   Information.    Throughout   the
                  Restricted   Period,   DeSantis   agrees   to   maintain   the
                  confidentiality  of,  and shall  not  disclose  to anyone  not
                  employed by any of the  Companies  nor use for his own benefit
                  or for the benefit of any third party,  without  prior written
                  consent  of  the  Corporation,   any  confidential  matter  or
                  information  of  any  of  the  Companies  including,   without

                  information,  plans  for  future  development  and  any  other
                  information  of like nature to the extent such  information is

                  of the Companies  without specific public disclosure shall not
                  constitute    a   release   of   DeSantis'    obligation    of
                  confidentiality.

                  Consulting  Agreement  or at  any  time  the  Corporation  may

                  Companies,  including  all  copies  of  such  materials  which

                  extent reasonably  required by DeSantis in connection with any
                  tax audit or other government inquiry.

                           (e)   Inventions.   Any  invention,   improvement  or
                  discovery,   whether  or  not  patentable;  any  copyrightable
                  materials; any trademark or service mark; and any trade secret
                  that  relates  to the past or present  business  of any of the
                  Companies (including research and evaluation),  which DeSantis
                  may have conceived,  made, developed or authored, either alone
                  or in  conjunction  with  others,  in the  course of his prior
                  employment  by the  Acquired  Company,  shall  be the sole and
                  exclusive  property of the  Acquired  Company.  DeSantis  will
                  disclose  to  the  Acquired  Company,   each  such  invention,
                  improvement,  discovery,  copyrightable  material,  trademark,
                  service mark,  or trade secret and will whenever  requested to
                  do so  by  the  Corporation,  promptly  execute  any  and  all
                  applications,  assignments  and  other  instruments  which the
                  Corporation  shall  deem  necessary  in order to apply for and
                  obtain  letters  patent of the United  States  and/or  foreign
                  countries for such invention, improvement or discovery or U.S.
                  or   foreign   registrations   with   respect   to  any   such
                  copyrightable material, trademark or service mark and in order
                  to assign and convey to the Acquired  Company or its order the
                  sole and  exclusive  right,  title and interest in and to such
                  invention,  improvement,  discovery,  copyrightable  material,
                  trademark, service mark, or trade secret.

                           (f) Remedies.  DeSantis recognizes that, in the event
                  that any of the provisions of this Section 1 are violated, the
                  damage  and  loss  to  the  Corporation  would  be  immediate,
                  irreparable and incalculable.  The parties,  therefore,  agree
                  that in the event of a violation of any of the  provisions  of
                  this Section 1, DeSantis shall  immediately  forfeit the right
                  to receive any  additional  fees or payments of any kind under
                  both this Agreement and the Consulting  Agreement  (except for
                  accrued  fees for services  previously  rendered and except as
                  otherwise  provided in Section 7 of the Consulting  Agreement,
                  the  provisions  of which shall also apply with respect to the
                  payment of the  consideration  to which  DeSantis  is entitled
                  hereunder) and the right to exercise any


<PAGE>



                  unvested  portion of the Option  referred to in the Consulting
                  Agreement.  In addition,  the Corporation shall be entitled to
                  specific  performance  of Section 1 of this  Agreement  and to
                  injunctive  relief,  whether  mandatory  or  prohibitory,   to
                  prevent  the  loss  of,  the   unauthorized   use  of  or  the
                  dissemination  of,  any  confidential   information  or  other
                  matter. Nothing contained herein,  however, shall restrict the
                  Corporation's  right to pursue  any other  remedy at law or in
                  equity  with  respect to such  breach or  violation  including
                  without limitation the right to seek recovery of any fees paid
                  to DeSantis  hereunder  and other  damages which are available
                  under applicable law.

                  2. Payment for Agreement Not to Compete.  In  consideration of
the promises,  restrictions and obligations set forth in or imposed by Section 1
hereof,  the Corporation  shall pay DeSantis the sum of $3,500,000  which amount
shall be paid in two equal installments, the first of which shall be paid on the
Effective Date and the second of which shall be paid on the first anniversary of

                 VALUE HEALTH, INC. TO ACQUIRE DIAGNOSTEK, INC.
        To Create Largest Independent Prescription Drug Benefit Manager

AVON, CONN. & ALBUQUERQUE,  N.M., MARCH 27, 1995 -- Value Health, Inc. (NYSE:VH)
and  Diagnostek,  Inc.  (NYSE:DXK)  today  announced  that  they  have  signed a
definitive  agreement  whereby Value Health will acquire  Diagnostek in a merger
valued at close to $480 million.

The merger will create the nation's  largest  independent  prescription  benefit
management (PBM) company covering approximately 32 million lives, of which about
24 million  are served by retail or mail  service  pharmacy  benefits,  and with
combined  1994 PBM  revenues  of more than  $1.1  billion.  When  pharmaceutical
manufacturer-owned  PBMs are included in the comparisons,  the new company would
rank  second  in  revenues  and third in  covered  lives  and drug  spend  under
management.

Terms of the  transaction  call for each share of Diagnostek to be exchanged for
0.55 shares of Value Health's stock. The transaction  will provide  shareholders
of  Diagnostek  with an  indicated  value of  $18.84  per  share  based on Value
Health's  closing  stock price on Friday,  March 24,  1995.  Actual  transaction
values  will  depend  on  Value  Health's  closing  stock  price  on the day the
transaction  is  completed.  The  transaction  is intended  to be  tax-free  and
accounted for as a pooling-of-interests, and could close as early as June.

"We believe that relative size will be an important  determinant  of PBM success
in the future,"  said Robert E.  Patricelli,  Chairman and CEO of Value  Health.
"Combining  our  ValueRx  subsidiary  with  Diagnostek  will  give us a  leading
competitive  position and the opportunity to preserve the best practices of both
companies so that we can better serve our customers," Patricelli added.

"The transaction will be non-dilutive to Value Health's earnings going forward,"
Patricelli  said, "and there will be  opportunities  for  significant  synergies
beginning in 1996. We will be taking a  restructuring  reserve in the quarter in
which the deal closes," he added.

"We're pleased to be joining an  outstanding  managed care company such as Value
Health,  and feel the union will afford our employees many opportunities to grow
with the new company," said Nunzio P. DeSantis,  Diagnostek's founder,  Chairman
and Chief  Executive  Officer.  DeSantis  will leave  active  management  of the
company  at  closing  to pursue  other  business  interests  and will serve as a
consultant to Value Health. Barry M. Smith, Chairman and Chief Executive Officer
of ValueRx, will head the new combined PBM

company. Smith commented,  "I want to commit to our customers and employees that
we are joining the ValueRx and  Diagnostek  resources in order to build the vary
best PBM and institutional pharmacy enterprise in the country."

Diagnostek and ValueRx are both providers of integrated drug management services
designed to contain the costs of prescription  benefit  programs.  The companies
arrange for the provision of  prescription  drugs through their own mail service
dispensing facilities and through contracted networks of retail pharmacies.

Diagnostek was founded in 1983 as a provider of stand-alone  diagnostic  imaging
centers,  and entered the PBM  business in 1988 and the  institutional  pharmacy
business  the  following  year.  Headquartered  in  Albuquerque,  NM,  it is the
nation's third largest provider of mail order services  dispensing more than 3.5
million mail order  prescriptions in 1994. It maintains mail order facilities in
Albuquerque  and  Bensalem,  PA, and  operates  a national  network of more than
51,000 retail pharmacies which dispensed more than 8.9 million  prescriptions in
1994.  Its mail and retail drug programs  combined cover about 16 million lives.
The company has 1400 employees, and had 1994 revenues from all divisions of $656
million.

Diagnostek also provides  pharmacy  contract  management  services to hospitals,
nursing homes, HMOs and other institutions.  Its institutional pharmacy business
is comprised of HPI Health Care Services,  Inc., acquired from Omnicare in 1989,
and  Diagnostek  Pharmacy  Inc.,  originally  part of Chronitech and acquired in
1993. HPI primarily  manages hospital  pharmacies and services 130 facilities in
the U.S. and one in Canada.  Diagnostek Pharmacy provides specialty services for
HIV/AIDS patients and has pharmacies in San Francisco and Los Angeles, CA.

ValueRx,  headquartered  in Scottsdale,  AZ, recently opened a  state-of-the-art
mail order  facility  in  Davenport,  IA and has mail order and retail  programs
covering 8 million  lives and  another 8 million  lives  under drug  utilization
review programs.  ValueRx works through 37,000 retail pharmacies in its national
network.  ValueRx dispensed more than 34.4 million mail and retail prescriptions
in 1994 and had 1994 revenues of $660 million.

Value Health, Inc., ValueRx's parent company, is a leading provider of specialty
managed  care  benefit  programs  and health care  information  services.  Value
Health's  specialty  managed care benefit programs include  prescription  drugs,
mental  health and substance  abuse and workers'  compensation.  Value  Health's
health care information  services include clinically based  precertification and
claims  review,  provider  profiling,  claims  cost  analysis,   evaluation  and
management of health benefit providers,  health policy and management consulting
and disease  management program  development.  Value Health provides services to
more than 64 million  people and its  customers  include 58 of the  nation's 250
largest corporations.
