(collectively,  the "Related Documents").  Capitalized terms not defined in this
Agreement  shall  have  the  meanings  given  them  in  the  Related  Documents,
applicable to each respective SHCR Stockholder.

     The  parties  to this  Agreement  desire  to set  forth  the terms of their
interest in the securities of SHCR.

     In  consideration  of the foregoing and the mutual covenants and agreements
contained in this Agreement, the parties to this Agreement agree as follows:

ARTICLE I  ACQUISITION OF SECURITIES
- ---------  -------------------------

     Section  1  Acquisition  of SHCR  Common  Stock  by SHCR  Stockholders.  In
connection  with the  execution  and delivery of the Related  Documents  and the
consummation of the transactions  contemplated by the MSA, each SHCR Stockholder
has been issued by SHCR the respective number of shares of SHCR Common Stock (as
defined in the Purchase Option  Agreement),  set forth opposite the name of that
Stockholder on Schedule A to this Agreement.

ARTICLE II  THE CLOSING
- ----------  -----------

     Section 1 Closing. The delivery and acceptance of the shares of SHCR Common
Stock being acquired by the SHCR Stockholders  pursuant to the Related Documents
applicable to each respective SHCR  Stockholder  (the "Closing  Shares"),  shall
take  place at the  offices of  Sheridan  concurrently  with the  Closing of the
transactions contemplated by the Related Documents, or at a later date as agreed
to in writing by the parties and subject to satisfaction or waiver of all of the
conditions  set forth in the Related  Documents and in this  Agreement.  For the
purposes of this Agreement, the term "Closing Shares" shall mean: (a) any shares



of SHCR  Common  Stock  issued  at  Closing  or at a later  date as agreed to in
writing  by the  parties,  pursuant  to the  Related  Documents;  and,  (b)  any
securities  of  SHCR  issued  or  issuable  with  respect  to any of the  shares
described  in clause (a) above by way of a stock  dividend  or stock split or in
connection with a combination of shares, recapitalization, merger, consolidation
or  other  reorganization  (it  being  understood  that  for  purposes  of  this
Agreement,  a person  will be deemed to be a holder of Closing  Shares  whenever
that  person  has the  right to then  acquire  or obtain  from SHCR any  Closing
Shares, whether or not that acquisition has actually been effected).

ARTICLE III  RESTRICTIONS ON TRANSFER
- -----------  ------------------------

     Section 1     Restrictions on Transfer of Closing Shares.

          (a) Each SHCR Stockholder agrees not to offer, transfer, donate, sell,
assign, pledge, hypothecate or otherwise dispose of (collectively "Transfer" and
the result of any of these  actions is a "Transfer")  any Closing  Shares now or
hereafter  acquired or other rights in respect to those Closing Shares or rights
pursuant to this  Agreement,  whether  occurring  voluntarily or  involuntarily,
directly or indirectly, or by operation of law or otherwise,  except that a SHCR
Stockholder  may Transfer  Closing  Shares in accordance  with the provisions of
Article III, Section 1(b).

          (b)  Notwithstanding   anything  in  this  Agreement,   the  following
transactions  shall be exempt from the  prohibition on Transfers in Section 1 of
this Article III:

               (i) Transfers  between a SHCR  Stockholder  and the trustees of a
          trust  revocable  by  that  SHCR   Stockholder   alone  and  the  sole
          beneficiary of which is that SHCR Stockholder;

               (ii)  Transfers  by  gift  by a SHCR  Stockholder  to  that  SHCR
          Stockholder's  spouse or issue or to the  trustees  or a trust for the
          benefit of that spouse and/or issue;

               (iii)  Transfers   between  a  SHCR  Stockholder  and  that  SHCR
          Stockholder's guardian or conservator; and,

               (iv)  Transfers  upon the  death of a SHCR  Stockholder  by will,
          intestacy laws or the laws of survivorship to that SHCR  Stockholder's
          personal representatives, heirs or delegatees.

     provided,  however,  that,  except  in the case of  Transfers  pursuant  to
Article III, the transferee  agrees in writing for the benefit of the other SHCR
Stockholders  and SHCR, as a condition to that  Transfer,  to be bound by all of
the provisions of this Agreement to the same extent as was the transferor  prior
to that Transfer;  and provided,  further,  that any of these  transferees shall
take all Closing Shares and rights so transferred  subject to all the provisions
of this  Agreement as if those  Closing  Shares or rights were still held by the

                                       2


SHCR  Stockholder  who  made  the  Transfer.  If any  Transfer  is  effected  in
accordance with the provisions of this Article III, Section 1(b)(i), (ii), (iii)
or (iv), then the transferee  shall be referred to as a "Permitted  Transferee,"
and for all  purposes  of  this  Agreement  unless  expressly  indicated  to the
contrary,  the Permitted  Transferee shall be deemed to be a "SHCR Stockholder,"
but only to the extent that the transferor was included  within that  definition
prior to the transfer.

          (c) If any  Transfer  by a  SHCR  Stockholder  is  made  or  attempted
contrary to the provisions of this Agreement,  that purported  Transfer shall be
void ab initio;  SHCR and the other SHCR  Stockholders  (and their  transferees)
shall have, in addition to any other legal or equitable  remedies which they may
have,  the right to enforce  the  provisions  of this  Agreement  by actions for
specific  performance (to the extent  permitted by law); and SHCR shall have the
right to refuse to recognize any  Transferee of a SHCR  Stockholder  pursuant to
any  Transfer  that is made or  attempted  contrary  to the  provisions  of this
Agreement as one of its stockholders for any purpose.

     Section 2 Termination of Restrictions  on Transfer of Closing  Shares.  The
provisions of this Article III, as they relate to certain Closing Shares,  shall
terminate and be of no further force and effect as of March 5, 1999.

ARTICLE IV  REPRESENTATIONS AND WARRANTIES OF THE SHCR STOCKHOLDERS
- ----------  -------------------------------------------------------

     By execution of a counterpart of this  Agreement,  any SHCR  Stockholder at
the time of that execution makes the following representations and warranties to
SHCR,  these  representations  and warranties  being made in connection with the
issuance of the Closing Shares:

     1.  This  Agreement  is  made  in  reliance  on  each  SHCR   Stockholder's
     representations  to SHCR  that all  Closing  Shares  acquired  by that SHCR
     Stockholder will be acquired for investment for that SHCR Stockholder's own
     account, not as a nominee or agent, and not with a view toward distribution
     of any part thereof,  and that SHCR  Stockholder  has,  except as otherwise
     contemplated  in the Related  Documents,  no present  intention of selling,
     granting participation in, or otherwise distributing those Closing Shares.

     2. Each SHCR  Stockholder  understands  that the Closing Shares will not be
     registered  under  the  Securities  Act,  on the  ground  that the sale and
     issuance of the same are exempt from registration under Section 4(2) of the
     Securities Act, and that SHCR's reliance on that exemption is predicated on
     the representations of each SHCR Stockholder set forth in this Agreement.

     3. Each SHCR  Stockholder  understands  that the Closing  Shares may not be
     sold,  transferred or otherwise disposed of without  registration under the
     Securities  Act or an  exemption  therefrom,  and that in the absence of an
     effective   registration  statement  covering  the  Closing  Shares  or  an
     available exemption from registration under the Securities Act, the Closing
     Shares must be held  indefinitely.  Each SHCR  Stockholder  agrees that, in

                                       3


     addition to any other applicable limitations on the transfer of the Closing
     Shares, in no event will it make a transfer, pledge or other disposition of
     any of the Closing Shares other than pursuant to an effective  registration
     statement  under  the  Securities  Act,  unless  and  until:  (i) that SHCR
     Stockholder shall have notified SHCR of the proposed  disposition and shall
     have  furnished to SHCR a statement of the  circumstances  surrounding  the
     disposition;  and, (ii) if Sheridan  reasonably  determines Rule 144 is not
     available as an exemption,  then at the expense of the SHCR  Stockholder or
     its  transferee,  it shall  have  furnished  to SHCR an  opinion of counsel
     reasonably  satisfactory  to SHCR and its  counsel to the  effect  that the
     proposed  transfer,  pledge  or  other  disposition  may  be  made  without
     registration under the Securities Act.

     4.  Each  SHCR  Stockholder:  (i) by  reason  of his  or her  business  and
financial  experience,  has that  knowledge,  sophistication  and  experience in
business and  financial  matters as to be capable of  evaluating  the merits and
risks of his or her investment in the Closing Shares;  and, (ii) believes his or
her financial  condition and investments  enable him or her to bear the economic
risk of a  complete  loss of the  Closing  Shares.  Each  SHCR  Stockholder  has
consulted  with its own advisers  with respect to their  proposed  investment in
SHCR.  Each SHCR  Stockholder  has had the  opportunity  to ask questions and to
receive answers concerning the financial condition,  operations and prospects of
SHCR and the terms and conditions of the SHCR Stockholder's  investment, as well
as the opportunity to obtain any additional  information necessary to verify the
accuracy of information furnished in connection therewith that SHCR possesses or
can acquire  without  unreasonable  effort or  expense.  In  addition,  the SHCR
Stockholder  acknowledges  that he or she has received prior to the execution of
this Agreement the following documentation:  (i) a prospectus for SHCR, dated as
of October 31, 1995 (ii) annual  reports for 1995 and 1996;  (iii) 10Ks for 1995
and 1996;  and,  (iv) SHCR's Form 10-Q for the time period ended  September  30,
1997. Each SHCR Stockholder has carefully  reviewed that  documentation  and has
had the  opportunity to review that  documentation  with his or her own advisers
and SHCR.

6. Each SHCR  Stockholder  is an individual who either (i) has an individual net
worth,  or joint net worth  with that SHCR  Stockholder's  spouse as of the date
hereof which exceeds One Million Dollars ($1,000,000.00); or (ii) has had income
in excess of Two Hundred Thousand  Dollars  ($200,000.00) in each of the two (2)
most recent years or joint income with that SHCR Stockholder's  spouse in excess
of Three Hundred Thousand Dollars ($300,000.00) in each of those years and has a
reasonable expectation of reaching the same income level in the current year.

     7. Each SHCR  Stockholder's  legal  domicile for purposes of the applicable
securities  laws is as set  forth  on  Schedule  A  attached  to this  Agreement
executed by that SHCR Stockholder.

     8.  This  Agreement  and each  agreement,  instrument  and  document  to be
executed and delivered by each SHCR  Stockholder  pursuant to or as contemplated
by this  Agreement  constitute,  or when  executed  and  delivered  by that SHCR

                                       4


Stockholder  will  constitute,  valid  and  binding  obligations  of  that  SHCR
Stockholder enforceable in accordance with their respective terms.

     9. The execution, delivery and performance by each SHCR Stockholder of this
Agreement and each agreement, document and instrument:

     (d) do not and will not  violate  any  laws,  rules or  regulations  of the
     United  States or any state or other  jurisdiction  applicable to that SHCR
     Stockholder,  or require  that SHCR  Stockholder  to obtain  any  approval,
     consent or waiver of, or to make any filing  with,  any person that has not
     been obtained or made; and

     (e) do not and  will not  result  in a breach  of,  constitute  a   default
         under,  accelerate any obligation under  or  give  rise to  a  right of
         right  of  termination  of  any  indenture  or loan   agreement or  any
         other agreement, contract, instrument, mortgage, lien,  lease,  permit,
         authorization, order, writ, judgment, injunction, decree, determination
         or arbitration award to which that SHCR Stockholder is a  party  or  by
         which the property of that SHCR  Stockholder  is bound or affected,  or
         result in the creation or imposition of any   mortgage,  pledge,  lien,
         security  interest  or other  charge or encumbrance  on  any   of   the
         assets  or  properties  of that  SHCR Stockholder.

provisions  contained  in this  Agreement,  or the  application  thereof  in any
circumstances,  is held invalid, illegal or unenforceable in any respect for any
reason,  the validity,  legality and  enforceability  of that provision in every
other respect and of the remaining  provisions contained in this Agreement shall
not be in any way impaired thereby, it being intended that all of the rights and
privileges of the parties to this Agreement  shall be enforceable to the fullest
extent permitted by law.
