         SECTION 3.  Representations  and  Warranties.  Each of Holding  and the
Borrower hereby represents and warrants as follows:

                  (a) The execution, delivery and performance by each Loan Party
         of any of the Amendment  Documents and Loan  Documents to which it is a
         party, as amended  hereby,  and the  consummation  of the  transactions
         contemplated hereby and thereby, are within such Loan Party's corporate
         powers,  have been duly authorized by all necessary  corporate  action,
         and do not (i)  contravene  such Loan Party's  charter or bylaws,  (ii)
         violate any law (including, without limitation, the Securities Exchange
         Act  of  1934),  rule,  regulation   (including,   without  limitation,
         Regulation X of the Board of Governors of the Federal Reserve  System),
         order,  writ,  judgment,  injunction,  decree,  determination  or award
         applicable  to such Loan Party,  (iii)  conflict  with or result in the
         breach of, or constitute a default under, any contract, loan agreement,

         of trust,  lease or other  instrument  binding on or affecting any Loan
         Party, any of its Subsidiaries or any of their properties other than as
         specified  in the Credit  Agreement,  or (iv) except for Liens  created
         under the Collateral Documents, as amended hereby, result in or require
         the creation or  imposition  of any Lien upon or with respect to any of
         the  properties of any Loan Party or any of its  Subsidiaries.  No Loan
         Party or any of its Subsidiaries is in violation of any such law, rule,
         regulation, order, writ, judgment, injunction, decree, determination or
         award or in breach of any such  contract,  loan  agreement,  indenture,
         mortgage,  deed of trust,  lease or other instrument,  the violation or
         breach  of which is  reasonably  expected  to have a  Material  Adverse
         Effect.

                  (b) No  authorization  or approval or other  action by, and no
         notice to or filing with, any governmental authority or regulatory body
         or any other third party is required to be obtained by the Loan Parties
         in connection  with the execution and delivery,  or
<PAGE>
                                       5

         performance  by any Loan  Party of any of its  obligations  under,  any
         Amendment Document to which it is a party.

                  (c)  Each  Amendment  Document  has  been  duly  executed  and
         delivered by each Loan Party party thereto, and is the legal, valid and
         binding  obligation of such Loan Party,  enforceable  against such Loan
         Party  in  accordance  with  its  terms  except  as may be  limited  by
         bankruptcy,  insolvency,  reorganization,   moratorium  or  other  laws
         relating to or limiting  creditors'  rights or by equitable  principles
         generally.

                  (d) No Loan Party has an  existing  claim  against  any Lender
         Party  arising  out of,  relating  to or in  connection  with  the Loan
         Documents.

                  (e) No Loan Party is in breach of, or in default under, the 10
         5/8 % Senior Notes due 2007 issued by the Borrower, any contract,  loan
         agreement,   indenture,   mortgage,  deed  of  trust,  lease  or  other
         instrument,  binding  on or  affecting  any  Loan  Party,  any  of  its
         Subsidiaries or any of their properties,  where the consequence of such
         default is to confer rights upon any person against the Borrower or any
         of its Subsidiaries which, if exercised,  can be reasonably expected to
         have a Material Adverse Effect.

                  (f) Set forth on Schedule A hereto is a complete  and accurate
         list  of all  real  property  owned  by any  Loan  Party  or any of its
         Subsidiaries,  showing as of the date hereof the street address, county
         or other relevant  jurisdiction,  state,  record owner and showing also
         the  Loan  Parties  which  maintain  Equipment  and  Inventory  at such
         location.  Each Loan Party or such Subsidiary has good,  marketable and
         insurable fee simple title to such real property, free and clear of all
         Liens, other than Liens created or permitted by the Loan Documents.

                  (g) Set forth on Schedule B hereto is a complete  and accurate
         list of all leases of real  property  under which any Loan Party or any
         of its  Subsidiaries  is the lessee,  showing as of the date hereof the
         street address,  county or other relevant jurisdiction,  state, lessor,
         lessee and showing also the Loan Parties which  maintain  Equipment and
         Inventory at such  location.  To the best of the  knowledge of the Loan
         Party or Subsidiary  which leases the property,  each such lease is the
         legal, valid and binding obligation of the lessor thereof,  enforceable
         in accordance with its terms.

                  (h) All of the  Equipment  and  Inventory  of each  Grantor is
         located at the places listed on Schedules A and B.

         SECTION 4. Waiver and Release.  The  Borrower and Holding  hereby waive
and  agree  not  to  assert  any  claims  or  causes  of  action   against   the
Administrative Agent, the Syndication Agent, the Documentation Agent, any Lender
Party  or  any  of  their  Affiliates,  or any  of  their  respective  officers,
directors,  employees, attorneys and agents, on any theory of liability, whether
known or unknown,  matured or contingent,  including,  without  limitation,  for
special,  indirect,  consequential  or  punitive  damages,  arising  out  of  or
otherwise  relating to, or in connection  with, this Amendment,  the Facilities,
the actual or proposed  use of the  proceeds  of

transactions entered into in connection therewith.

         SECTION 5. Reference to and Effect on the Loan Documents.

                  (a) On and after the  Effective  Date,  each  reference in the
         Credit Agreement to "this Agreement", "hereunder", "hereof" or words of
         like import  referring to the Credit  Agreement,  and each reference in
         the Notes and the  other  Loan  Documents  to "the  Credit  Agreement",
         "thereunder", "thereof" or words of like import referring to the Credit
         Agreement,  shall mean and be a reference to the Credit  Agreement,  as
         amended and otherwise modified hereby.

                  (b) The Credit Agreement, the Notes and each of the other Loan
         Documents,   except  to  the  extent  of  the   amendments   and  other
         modifications specifically provided above, are and shall continue to be
         in full force and effect and are hereby in all  respects  ratified  and
         confirmed.  Without  limiting  the  generality  of the  foregoing,  the
         Collateral Documents and all of the Collateral described therein do and
         shall  continue  to secure the payment of all  Obligations  of the Loan
         Parties  under and in respect  of the Loan  Documents,  as amended  and
         otherwise modified by this Amendment.

                  (c)  The  execution,   delivery  and   effectiveness  of  this
         Amendment shall not, except as expressly provided herein,  operate as a
         waiver of any right,  power or remedy of any Lender  Party or any Agent
         under  any of the  Loan  Documents,  nor  constitute  a  waiver  of any
         provision of any of the Loan Documents.

         SECTION 6. Costs and Expenses.  The Borrower hereby agrees to pay, upon
demand, all costs and expenses of the Administrative  Agent (including,  without
limitation,  the reasonable fees and expenses of counsel and financial  advisors
for the  Administrative  Agent) in connection with the  preparation,  execution,
delivery,  administration,  syndication,  modification  and  amendment  of  this
Amendment and the other  documents,  instruments  and agreements to be delivered

Agreement.

         SECTION 7. Execution in Counterparts. This Amendment may be executed in
any  number  of  counterparts  and  by  different  parties  hereto  in  separate
counterparts,  each of which when so executed  shall be deemed to be an original
and all of which taken  together shall  constitute  one and the same  agreement.
Delivery of an executed  counterpart  of a signature  page to this  Amendment by
telecopier shall be effective as delivery of a manually executed  counterpart of
this Amendment.

         SECTION 8.  Governing  Law.  This  Amendment  shall be governed by, and
construed in accordance with, the laws of the State of New York.

         SECTION 9. Waiver of Jury Trial.  Each of the Borrower,  the Subsidiary

Premier.  The  parties  hereto  agree that up to six  hundred  and  twenty  five
thousand  dollars  ($625,000)  of the Working  Capital  Loan  proceeds  shall be
applied as and to the extent necessary for such purchase, but that any remaining
amounts of not less than eight hundred seventy-five  thousand dollars ($875,000)
may be used by OIS for general working capital purposes.

party hereto,  constitutes a legal,  valid and binding  agreement of MediVision,
enforceable against MediVision in accordance with its terms (subject,  as to the
enforcement of remedies, to applicable bankruptcy,  reorganization,  insolvency,
moratorium and similar laws affecting  creditors'  rights,  and, with respect to
the remedy of specific performance, equitable doctrines applicable thereto).

         2.2 No  Conflicts.  The  execution,  delivery and  performance  of this
Agreement  by  MediVision  will not (a)  constitute a breach or violation of any
provisions of  MediVision's  articles of  incorporation  or bylaws or comparable
charter  documents,  (b)  result in a  violation  of any law,  rule,  ordinance,
regulation,  order,  judgment or decree  applicable to or by which MediVision or
any of its assets or  properties  is bound,  or (c) conflict with or result in a

stock split, stock dividend, recapitalization, merger, or similar event shall be
stamped or otherwise  imprinted with an  appropriate  restrictive  legend.  Each
certificate  representing  the purchased shares may be endorsed with any legends
required by any state blue sky laws and/or the following legend:

which  conflict,  breach or default would have a material  adverse effect on the

(1) to own, lease, license or use its properties now owned, leased,  licensed or
used and proposed to be owned,  leased,  licensed or used or (2) to carry on its

                  (a) MediVision  acknowledges  and agrees that neither  Premier
nor OIS has made any  representations  or warranties to MediVision in connection
with the  transactions  contemplated  hereby  regarding the business,  condition
(financial or otherwise),  results of operations,  prospects or any other aspect
of the operations of OIS.

                  (b) MediVision agrees to promptly notify in writing OIS of any
events, facts or occurrences which would constitute or result in a breach of any
representation  or warranty made by MediVision  contained in this Agreement or a
breach of any  covenant,  agreement  or  obligation  of  MediVision  under  this
Agreement; provided, however, that no such disclosure shall be deemed to cure or
relieve any such breach or default.

                  (c)  Appointment  of Directors,  CEO. The parties hereto shall
take  commercially  reasonable  steps, in compliance with applicable law and the

designation by MediVision,  of new directors, who shall constitute a majority of

         4.3 Further  Assurances.  Subject to the terms and conditions  provided

each party to consummate the transactions  contemplated  hereby shall be subject
to the  satisfaction  at or  prior  to the  Closing  of  each  of the  following
conditions:

                  (a) Bankruptcy  Court Approval.  The federal  bankruptcy court
administering  Premier's  reorganization under Chapter 11 of the U.S. Bankruptcy

Transactions contemplated hereby and thereby.

                                       10
<PAGE>

                  (b) No  Injunctions,  Restraints or  Litigation.  No temporary
restraining order,  preliminary or permanent injunction or other order issued by
any court of competent  jurisdiction  or other legal  restraint  or  prohibition
preventing  consummation of the transactions  contemplated  hereby is in effect.
There  is no  pending  or  threatened,  claim,  action,  suit  or  other  legal,
administrative, investigative or arbitration proceeding in which it is sought to
restrain,  enjoin or prohibit the consummation of the transactions  contemplated
hereby or to obtain damages or other monetary or equitable  relief in connection
therewith.

                  (c)  Representations  and Warranties.  The representations and
warranties  of the other party  hereto  contained  in this  Agreement  are true,
accurate and complete in all material respects as of the Closing Date.

                  (d)  Performance  of  Agreement.  The other  party  hereto has
performed  and  satisfied  in all  material  respects  each  of  the  covenants,
agreements  and  obligations  required to be performed and satisfied by it under
this Agreement and the Purchase Agreement on or prior to the Closing Date.

                  (e) Purchase Agreement.  The transactions  contemplated by the
Purchase Agreement shall be consummated contemporaneously with the Closing.

                  (f)  Rights  Agreement.  OIS shall  have  amended  the  Rights
Agreement,  dated as of December 31, 1997,  as amended from time to time, by and
between OIS and American Securities Transfer, Inc. (the "Rights Agreement"),  to
provide that (i) none of the  transactions  contemplated  by this Agreement will
trigger a Distribution  Date and (ii) MediVision will not be deemed an Acquiring
Person thereunder, as those terms are defined in the Rights Agreement.

                                   ARTICLE VI

                                   TERMINATION

         6.1      Termination. This Agreement may be terminated at any time:

                  (a)      by mutual written consent of MediVision and OIS;

                  (b) by either party hereto if the Purchase  Agreement has been
terminated  or the  Closing  has not  occurred  by October  31,  2000,  and this
Agreement  has not  previously  been  terminated;  provided,  however,  that the
failure  to  consummate  the  Closing by such date is not a result of either the
failure by the party so electing to terminate  this  Agreement to perform any of
its  obligations  hereunder  or the  breach  by the  party  so  electing  of its
representations and warranties;

                  (c) by  MediVision  or OIS if OIS  enters  into  an  agreement
constituting a Superior Proposal;

                  (d) by any party hereto if the  Bankruptcy  Court  approves an
Overbid by any person or entity other than  MediVision or any of its Affiliates;
and

                                       11
<PAGE>

                  (e) by any party hereto in the event any court or governmental
agency of competent  jurisdiction has issued an order, decree or ruling or taken
any  other  action   restricting,   enjoining  or  otherwise   prohibiting   the
transactions  contemplated hereby and such order, decree, ruling or other action
shall have become final and unappealable.

         6.2 Effect of  Termination.  In the event that this Agreement  shall be
terminated  pursuant to this Article VI, all further  obligations of the parties
under this Agreement  other than the  obligations  set forth in this Section 6.2
shall  terminate,  and there shall be no liability of any party to another party
except  for a  party's  breach  of any of its  obligations,  representations  or
warranties under this Agreement prior to the termination of this Agreement.

                                   ARTICLE VII

                                  MISCELLANEOUS

         7.1 Governing Law. This  Agreement  shall be governed by, and construed
in accordance  with, the laws of the State of California  (without giving effect
to conflicts of law principles thereof).

         7.2 Remedies  Cumulative.  Except as may otherwise be provided  herein,
the  remedies  provided  herein  shall be  cumulative  and  shall  not  preclude
assertion by either party hereto of any other rights or the seeking of any other
remedies against either party hereto.

         7.3  Brokerage.  Each party hereto will indemnify and hold harmless the
other  party  against  and in  respect  of any  claim  for  brokerage  or  other
commission  relative  to  this  Agreement  or to the  transactions  contemplated
hereby,  based in any way on agreements,  arrangements or understandings made or
claimed to have been made by such party with any third party.

         7.4 Severability.  Whenever possible,  each provision of this Agreement
shall be  interpreted  in such a  manner  as to be  effective  and  valid  under
applicable law, but if any provision of this Agreement shall be prohibited by or
invalid under applicable law, such provisions shall be ineffective to the extent
of such  prohibition or invalidity,  without  invalidating the remainder of such
provision or the remaining provisions of this Agreement.

         7.5 Notices.  Notices  required under this Agreement shall be deemed to
have been  adequately  given if delivered in person or sent to the  recipient at
its address (or facsimile number, as the case may be) set forth on the signature
page hereto or such other address as such party may from time to time  designate
in writing by certified mail (return receipt requested),  facsimile or overnight
courier in the manner provided in this Section 7.5.

         7.6      Amendments and Waivers.

                  (a) Any provision of this  Agreement  and the Working  Capital
Note may be amended or waived if, but only if,  such  amendment  or waiver is in
writing and signed, in the case of an amendment,  by each of the parties hereto,
or in the case of a  waiver,  by the  party  against  whom the  waiver  is to be
effective.

                                       12
<PAGE>

                  (b) No waiver by a party of any default,  misrepresentation or
breach of a warranty or covenant hereunder, whether intentional or not, shall be
deemed to extend to any prior or subsequent default, misrepresentation or breach
of a warranty or covenant  hereunder or affect in any way any rights  arising by
virtue of any prior or  subsequent  occurrence.  No  failure or delay by a party
hereto in exercising any right, power or privilege  hereunder shall operate as a
waiver  thereof nor shall any single or partial  exercise  thereof  preclude any
other or further exercise  thereof or the exercise of any other right,  power or
privilege.

         7.7 Survival.  All  representations  and warranties made by the parties
contained  in  this  Agreement  and the  respective  covenants,  agreements  and
obligations of the parties under this Agreement  shall survive the execution and
delivery of this Agreement for a period of three years following the Closing.

         7.8 Entire  Understanding.  This  Agreement  and the  agreements  to be
executed in connection herewith at the Closing, express the entire understanding
of the  parties  and  supersede  all prior and  contemporaneous  agreements  and
undertakings  of the  parties  with  respect to the  subject  matter  hereof and
thereof.

         7.9 Expenses.  Each party will pay all of its own  expenses,  including
attorney's  fees,  incurred in connection with the negotiation of this Agreement
and the Working Capital Note, the  performance of its obligations  hereunder and
under  the  Working  Capital  Note  and  the  consummation  of the  transactions
contemplated  by this  Agreement.  In the event of any  action  at law,  suit in
equity or  arbitration  proceeding in relation to this  Agreement or the Working
Capital Note, the prevailing party shall be paid by the other party a reasonable
sum for attorneys' fees and expenses incurred therein.

         7.10  Counterparts.  This Agreement may be executed in counterparts and
the signatures delivered by telecopy in the manner provided in Section 7.5, each
of which  shall be  deemed to be an  original  but which  taken  together  shall
constitute one agreement with the same effect as if the signatures were upon the
same instrument and delivered in person.

         7.11     Assignment; No Third-Party Beneficiaries.

                  (a)  Except  as  otherwise  expressly  provided  herein,  this
Agreement and the rights  hereunder  shall not be  assignable  or  transferable,
except to an Affiliate, by either party without the prior written consent of the
other party hereto;  provided that, if such  assignment or transfer is consented
to, such  assignee or  transferee  expressly  assumes in writing all of the such
party's obligations hereunder. Subject to the preceding sentence, this Agreement
shall be binding upon, inure to the benefit of and be enforceable by the parties
hereto and their respective successors and assigns.

                  (b) This  Agreement  is for the sole  benefit  of the  parties
hereto and their respective  successors and permitted assigns and nothing herein
expressed or implied  shall give or be  construed  to give to any Person,  other
than the parties hereto and such successors and permitted assigns,  any legal or
equitable rights hereunder.

                                       13
<PAGE>

knowledgeable  in the matters dealt with in this Agreement.  Each party has been
represented by experienced and  knowledgeable  legal counsel.  Accordingly,  any
rule  of  law  or  legal  decision  that  would  require  interpretation  of any
ambiguities  in this  Agreement  against  the party  that has  drafted it is not
applicable and is waived.

         7.13  Titles  and  Subtitles.  The titles  and  subtitles  used in this
Agreement  are  used  for  convenience  only  and  are not to be  considered  in
construing or interpreting this Agreement.

Sacramento,  or (in a case involving diversity of citizenship) the United States
District Court of the Northern District of California shall have jurisdiction of

other process in any such action or proceeding  may be made by either party upon
the other by  registered  or  certified  mail  directed to the  recipient at its
address  referenced  on the  signature  page hereto,  each party hereby  waiving
personal service thereof.

         7.15 WAIVER OF THE RIGHT TO TRIAL BY JURY. EACH PARTY HERETO WAIVES THE
RIGHT TO TRIAL BY JURY IN ANY ACTION OR PROCEEDING, WHETHER IN CONTRACT OR TORT,
