                    OMEGA COMPLETES NORTH TEXAS ACQUISITIONS

MEMPHIS - September 11 - Omega Health  Systems  (Nasdaq:  OHSI) today  announced
that  it had  completed  the  acquisition  of the  net  assets  of  EyeCare  and
SurgeryCenter  of North Texas (ECSC),  the  ophthalmology  practice of Wesley K.
Herman,  MD, and Bradford Pazandak,  MD, and acquired a controlling  interest in
SurgEyeCare,   an  ambulatory   surgery   center   located   adjacent  to  ECSC.
Simultaneously  with the acquisitions,  Omega entered into long-term  management
agreements with the  Herman-Pazandak  practice,  the related retina practice and
the surgery center.

Omega  acquired the net assets of ECSC in exchange  for 771,429  shares of Omega
common stock. The acquisition of the net assets of ECSC will be accounted for as
a pooling of interests. Omega acquired its 75% interest in SurgEyeCare for $4.55
million,  which  was  partially  funded  with the  proceeds  of a $3.28  million
acquisition  term loan from a commercial  bank.  The  acquisition of SurgEyeCare
will be accounted for as a purchase.

Tom Lewis,  President  & CEO of Omega,  commented  on the  Dallas  acquisitions,
"These acquisitions  represent a significant step forward for Omega in executing
its growth  through  acquisition  strategy.  The  Herman-Pazandak  practice is a
leader in  ophthalmology-optometry  programs in North Texas.  These acquisitions
will add  materially  to Omega's  revenues and  earnings and will be  materially
accretive to 1996 earnings per share."

Omega Health Systems is an integrated eye care services company, with operations
in  physician  practice  management,  managed eye care  programs,  eye  surgical
facilities,   excimer  laser  refractive  surgery  programs  and  an  ophthalmic
specialty supplies and equipment distribution company.

Certain statements in this press release consists of forward-looking  statements
based on  management's  current  expectations  that  are  subject  to risks  and
uncertainties  that could cause actual results to differ  materially  from those
set forth in or implied by forward-looking statements. These risks are described
in the  Company's  annual  report on Form 10-KSB filed with the  Securities  and
Exchange Commission.

                               EXCHANGE OF ASSETS
                               ------------------

        Subject to the terms and  conditions  hereof,  at  Closing,  P.A.  shall
transfer,  assign, convey and deliver to Omega North Texas and Omega North Texas
shall  acquire  from P.A.  all of the Assets of P.A.  Omega North Texas will not
acquire the  Excluded  Assets.  The P.A.  and Omega North Texas  intend that the
exchange  consummated  pursuant to this  Agreement  shall  qualify as a tax-free
reorganization  pursuant to the provisions of Section  368(a)(1)(C) of the Code.
In connection with such tax-free reorganization, it is anticipated that the P.A.
will liquidate and dissolve,  distributing its remaining  assets,  including the
Omega Stock  (hereinafter  defined),  to Dr. Herman and Dr. Pazandak.  After Dr.
Herman  and Dr.  Pazandak  notify  Omega  North  Texas  of the  liquidation  and
dissolution  of the P.A.  and  deliver  to Omega  North  Texas  the  certificate
representing the Omega Stock (endorsed in favor of Dr. Herman and Dr. Pazandak),
Omega shall issue,  upon receipt by Dr. Herman and Dr.  Pazandak of  appropriate
representations,  substantially in the form of EXHIBIT 2.1, two (2) separate new
certificates  (the  "Replacement  Shares")  replacing the Omega Stock,  one such
certificate  to be  issued  in the  name  of  Dr.  Herman  and  the  other  such
certificate to be issued in the name of Dr. Pazandak,  as directed by Dr. Herman
and Dr. Pazandak.  If the P.A. is liquidated promptly following  consummation of
the  exchange  hereunder,  Omega  North  Texas  and the  P.A.  will  report  the
transaction  on  their  respective  income  tax  returns  or  other  appropriate
schedules or  informational  returns as qualifying  for tax-free  reorganization
treatment under Section 368(a)(1)(C) of the Code. Omega North Texas shall not be
liable to the P.A.,  however, if the transaction does not ultimately result in a
tax-free  reorganization  unless  Omega  North Texas has  breached or  otherwise
violated  this  Agreement  in such a manner  so as to  render  the  contemplated
transaction as other than a tax-free reorganization.

                                   ARTICLE III
                                  CONSIDERATION
                                  -------------

      III.1 AMOUNT OF  CONSIDERATION.  As  consideration  for the Assets,  Omega
North Texas shall at Closing transfer to P.A., Omega Health Systems, Inc. Common
Stock (the "Omega  Stock")  valued at Three Million Six Hundred  Forty  Thousand
Dollars ($3,640,000) with the shares of Omega Stock valued at the average of the
closing  price of Omega Stock for the twenty (20) trading days ending August 31,
1996,  provided that the maximum  conversion  price shall be Six Dollars ($6.00)
per  share.  The Omega  Stock  will not be  registered,  and will be  restricted
securities  that are not  fully  transferrable,  except to the  extent  provided
herein, and the certificates representing the Omega Stock shall bear a legend to
that effect.


      III.2  REGISTRATION  RIGHTS.  The P.A.  will be  entitled  to  "piggyback"
registration  rights for  unregistered  Omega Stock on  registrations of Omega's
stock or  securities,  subject  to the  right of Omega and its  underwriters  to
reduce the number of shares of Omega Stock  proposed to be registered in view of
market  conditions,  and Omega shall  promptly  advise the P.A. of any  proposed



                                     - 7 -

registration.  Such underwriter's  "cutback" shall be applied proportionately to
all unregistered  Omega Stock or other  securities and unregistered  warrants or
stock  options  which  are  requesting  registration  at such time  pursuant  to
contractual  rights.  Omega may not  include  unregistered  Omega Stock or other
securities held by shareholders other than the P.A. (the "Non-P.A.  Stock") in a
registration statement pursuant to this SECTION 3.2 if such Omega Stock or other
securities were not granted  registration rights similar to the rights contained
in this SECTION 3.2 as a condition  to their  original  issuance,  except to the
extent that the amount of unregistered  Omega Stock  otherwise  included in such
registration  statement  would not thereby be diminished by the inclusion of the
Non-P.A.  Stock.  The  costs to  Omega  of  registering  such  Omega  Stock in a
piggyback  registration  shall be  borne  by  Omega,  except  that  underwriting
discounts  and  commissions  shall be paid by the P.A.,  and the costs of P.A.'s
counsel shall be paid by the P.A.

      III.3  TRANSFERABILITY OF OMEGA STOCK.  Provided any transferee under this
subsection  acknowledges any restrictions placed on the Omega Stock,  nothing in
this Agreement shall prevent the Omega Stock from being transferred in whole, or
in part,  to one or more members of the  respective  family of Dr. Herman or Dr.
Pazandak,  to a trust,  established for the respective  benefit of Dr. Herman or
Dr. Pazandak  and/or one or more of the members of the respective  family of Dr.
Herman or Dr. Pazandak, to a family partnership (general or limited) established
respectively  by Dr. Herman or Dr. Pazandak and/or one or more of the members of
the respective family of Dr. Herman or Dr. Pazandak, to any other entity that is
respectively  owned by Dr.  Herman  or Dr.  Pazandak  and/or  one or more of the
members of the respective family of Dr. Herman or Dr. Pazandak.

      III.4  REFERRALS.  The parties  agree that  nothing in this  Agreement  is
intended to violate state or federal health care laws or regulations  including,
but not limited to, those  listed in SECTION 6.10 herein,  nor shall any portion
of the consideration be construed as a payment for or inducement of the referral
of patients. P.A. shall be free to refer patients to whomever it sees fit in the
exercise of professional judgment, according to the convenience or preference of
the patient, or otherwise.

leases of the P.A.'s business,  leases of equipment and other personal  property
listed on SCHEDULE 6.7.1, and those material contracts  described in SECTION 6.7
hereof,  Omega North Texas assumes and agrees to be liable for any other amounts

Texas a final list of the Payables (the "Payables  List").  Without limiting the

negligence,  strict liability in tort,  product  liability or breach of warranty
claims;

      (c) any liability  arising out of any employee benefit plans maintained by
P.A.  for the benefit of any  employees  of P.A. or any other  liability of P.A.
with  respect  to any  employees,  including,  but  not  limited  to,  incentive
compensation plans,  severance pay, accrued salaries,  wages,  bonuses,  payroll
taxes, hospitalization and medical insurance,  deferred compensation of vacation
and sick pay;

      (d) any liability  attributable  to personal  property tax assessed by any
governmental  entity,  federal,  state or local, against any of the Assets to be
conveyed or leased hereunder,  such taxes to remain the  responsibility of P.A.;
and

      (e) any liability for any other tax assessed by any  governmental  entity,
federal,  state or local,  attributable to the business of P.A.  relating to the
period on or before the  Closing  including,  but not  limited  to, any  income,

       X.1  MEDIATION.  In the event a dispute arises out of or relating to this
Agreement,  or the breach thereof, and if said dispute cannot be settled through
negotiation, the parties agree to attempt in good faith to settle the dispute by
mediation  under the  Commercial  Mediation  Rules of the  American  Arbitration
Association.  Unless the parties  reach an  agreement  reduced to writing,  this
mediation will be non-binding, but the parties must participate in good faith in
non-binding mediation, before resorting to binding arbitration.

      X.2  BINDING  ARBITRATION.  Any  controversy  or claim  arising  out of or
relating  to  this  Agreement,  or its  breach,  not  satisfied  through  either
negotiation or mediation,  shall be settled by binding arbitration in accordance
with the Commercial  Arbitration Rules of the American Arbitration  Association.
Judgment upon the award  rendered by the  arbitrator may be entered in any court
having jurisdiction.

      As soon as reasonably  practical after  submission of a demand for binding
arbitration,  Omega  North  Texas  and the P.A.  shall  select  one  arbitrator,
agreeable to all parties.  This  arbitrator will be selected from lists prepared
by  the  American  Arbitration   Association.   From  the  American  Arbitration
Association list the parties will submit to the American Arbitration Association
a  ranked  list  of  arbitrators  which  are  acceptable.  The  highest  ranking
acceptable candidate will be selected by the American  Arbitration  Association.
If no arbitrators from the list composed by the American Arbitration Association
are acceptable by either of the parties,  the American  Arbitration  Association
will compile a second list.  This  procedure  will be followed until the parties
have selected an  arbitrator.  The results of the  arbitrator's  finding will be
binding on the parties.

                               EXCHANGE OF ASSETS
                               ------------------

        Subject to the terms and  conditions  hereof,  at  Closing,  P.A.  shall
transfer,  assign, convey and deliver to Omega North Texas and Omega North Texas
shall  acquire  from P.A.  all of the Assets of P.A.  Omega North Texas will not
acquire the  Excluded  Assets.  The P.A.  and Omega North Texas  intend that the
exchange  consummated  pursuant to this  Agreement  shall  qualify as a tax-free
reorganization  pursuant to the provisions of Section  368(a)(1)(C) of the Code.
In connection with such tax-free reorganization, it is anticipated that the P.A.
will liquidate and dissolve,  distributing its remaining  assets,  including the
Omega Stock  (hereinafter  defined),  to Dr. Herman and Dr. Pazandak.  After Dr.
Herman  and Dr.  Pazandak  notify  Omega  North  Texas  of the  liquidation  and
dissolution  of the P.A.  and  deliver  to Omega  North  Texas  the  certificate
representing the Omega Stock (endorsed in favor of Dr. Herman and Dr. Pazandak),
Omega shall issue,  upon receipt by Dr. Herman and Dr.  Pazandak of  appropriate
representations,  substantially in the form of EXHIBIT 2.1, two (2) separate new
certificates  (the  "Replacement  Shares")  replacing the Omega Stock,  one such
certificate  to be  issued  in the  name  of  Dr.  Herman  and  the  other  such
certificate to be issued in the name of Dr. Pazandak,  as directed by Dr. Herman
and Dr. Pazandak.  If the P.A. is liquidated promptly following  consummation of
the  exchange  hereunder,  Omega  North  Texas  and the  P.A.  will  report  the
transaction  on  their  respective  income  tax  returns  or  other  appropriate
schedules or  informational  returns as qualifying  for tax-free  reorganization
treatment under Section 368(a)(1)(C) of the Code. Omega North Texas shall not be
liable to the P.A.,  however, if the transaction does not ultimately result in a
tax-free  reorganization  unless  Omega  North Texas has  breached or  otherwise
violated  this  Agreement  in such a manner  so as to  render  the  contemplated
transaction as other than a tax-free reorganization.

                                   ARTICLE III
                                  CONSIDERATION
                                  -------------

      III.1 AMOUNT OF  CONSIDERATION.  As  consideration  for the Assets,  Omega
North Texas shall at Closing transfer to P.A. Omega Health Systems,  Inc. Common
Stock  (the  "Omega  Stock")  valued  at Nine  Hundred  Fifty  Thousand  Dollars
($950,000),  with the shares of Omega Stock valued at the average of the closing
price of Omega Stock for the twenty (20)  trading  days ending  August 31, 1996,
provided  that the maximum  conversion  price  shall be Six Dollars  ($6.00) per
share. The Omega Stock will not be registered, and will be restricted securities
that are not fully transferrable,  except to the extent provided herein, and the
certificates representing the Omega Stock shall bear a legend to that effect.

      III.2  REGISTRATION  RIGHTS.  The P.A.  will be  entitled  to  "piggyback"
registration  rights for  unregistered  Omega Stock on  registrations of Omega's
stock or  securities,  subject  to the  right of Omega and its  underwriters  to
reduce the number of shares of Omega Stock  proposed to be registered in view of
market  conditions,  and Omega shall  promptly  advise the P.A. of any  proposed
registration.  Such underwriter's  "cutback" shall be applied proportionately to
all unregistered  Omega Stock or other  securities and unregistered  warrants or
stock  options  which  are  requesting  registration  at such time  pursuant  to

                                     - 29 -


<PAGE>

contractual  rights.  Omega may not  include  unregistered  Omega Stock or other
securities held by shareholders other than the P.A. (the "Non-P.A.  Stock") in a
registration statement pursuant to this SECTION 3.2 if such Omega Stock or other
securities were not granted  registration rights similar to the rights contained
in this SECTION 3.2 as a condition  to their  original  issuance,  except to the
extent that the amount of unregistered  Omega Stock  otherwise  included in such
registration  statement  would not thereby be diminished by the inclusion of the
Non-P.A.  Stock.  The  costs to  Omega  of  registering  such  Omega  Stock in a
piggyback  registration  shall be  borne  by  Omega,  except  that  underwriting
discounts  and  commissions  shall be paid by the P.A.,  and the costs of P.A.'s
counsel shall be paid by the P.A.

      III.3  TRANSFERABILITY OF OMEGA STOCK.   Provided  any  transferee   under
this subsection acknowledges any restrictions placed on the Omega Stock, nothing
in this Agreement shall prevent the Omega Stock from being transferred in whole,
or in part, to one or more members of the respective family of Dr. Herman or Dr.
Pazandak,  to a trust,  established for the respective  benefit of Dr. Herman or
Dr. Pazandak  and/or one or more of the members of the respective  family of Dr.
Herman or Dr. Pazandak, to a family partnership (general or limited) established
respectively  by Dr. Herman or Dr. Pazandak and/or one or more of the members of
the respective family of Dr. Herman or Dr. Pazandak, to any other entity that is
respectively  owned by Dr.  Herman  or Dr.  Pazandak  and/or  one or more of the
members of the respective family of Dr. Herman or Dr. Pazandak.

      III.4  REFERRALS.  The parties  agree that  nothing in this  Agreement  is
intended to violate state or federal health care laws or regulations  including,
but not limited to, those  listed in SECTION 6.10 herein,  nor shall any portion
of the consideration be construed as a payment for or inducement of the referral
of patients. P.A. shall be free to refer patients to whomever it sees fit in the
exercise of professional judgment, according to the convenience or preference of
the patient, or otherwise.

                                   ARTICLE IV
                             LIABILITIES NOT ASSUMED
                             -----------------------

leases of equipment and other personal property listed on SCHEDULE 6.7.1,  those
material  contracts  described in SECTION 6.7 hereof,  and those payables of the
P.A. listed on SCHEDULE 4.1 hereof, it is expressly acknowledged and agreed that
Omega North Texas will not assume and shall not be liable,  either  expressly or

      (c) any  liability or claim arising out of or related to the operation and
use of the Assets  prior to the  Closing,  including,  without  limitation,  any

Medicaid  fraud or abuse,  overpayments  under any third party  payor  programs,
negligence,  strict liability in tort,  product  liability or breach of warranty
claims;

      (d) any liability  arising out of any employee benefit plans maintained by

and

      (f) any liability for any other tax assessed by any  governmental  entity,
federal,  state or local,  attributable to the business of P.A.  relating to the
period on or before the  Closing  including,  but not  limited  to, any  income,
franchise, excise, sales or use taxes.

                                    ARTICLE V
                                   THE CLOSING
                                   -----------

      The acquisition of the Assets as contemplated hereby shall close at a time
and  place  mutually  agreed  upon  by the  parties  after  satisfaction  of all
regulatory requirements, if any, and the conditions provided for in SECTIONS 8.1
AND 8.3  hereof.  At the  Closing,  all  assignments,  bills of sale  and  other
documents  required to be delivered  hereunder shall be delivered to Omega North
Texas.  Also at Closing,  Omega North Texas shall deliver executed copies of all
required  documents.  P.A. and Omega North Texas covenant and agree to use their

                     REPRESENTATIONS AND WARRANTIES OF P.A.,
                     ---------------------------------------
                           DR. HERMAN AND DR. PAZANDAK
                           ---------------------------

      P.A., Dr. Herman and Dr. Pazandak represent,  warrant,  covenant and agree
with Omega North Texas that:

      VI.1  TITLE;  CONDITION.  SCHEDULE  6.1.1  contains a  complete,  true and
correct list of P.A.'s Assets.  P.A. has good and marketable title to all of the
Assets,  and all Assets are in good  operating  condition.  Except as  otherwise
provided in this  Section 6.1,  the Assets are being  transferred  "as is, where
is." Except as disclosed on SCHEDULE  6.1.2 hereto,  none of such Assets of P.A.
is subject to sale by the P.A. under a sales contract or other agreement of sale
or subject to security  interests,  mortgages,  encumbrances,  liens  (including
income,  personal  property  and other  tax  liens)  or  charges  of any kind or
character.  Except as  indicated  on  SCHEDULE  6.1.2,  P.A.'s  Assets  shall be
conveyed to Omega North Texas free and clear of all liens and encumbrances.

      VI.2 AUTHORITY TO EXECUTE AND PERFORM AGREEMENT.  P.A. has the full right,
power and  capacity,  and all  authority  and  approval  required to enter into,
execute and deliver  this  Agreement  and to perform  and observe  fully  P.A.'s
obligations hereunder and to perform the transactions  contemplated hereby. This
Agreement  has been fully  executed  and  delivered by P.A. and is the valid and
binding obligation of P.A. enforceable in accordance with its terms.

      VI.3  LITIGATION.  Other than that set forth on SCHEDULE 6.3,  there is no
suit,  action,  proceeding  at law  or in  equity,  arbitration,  administrative
proceeding or other proceeding by any governmental entity pending or to the best
knowledge of P.A., Dr. Herman and Dr. Pazandak, threatened against, or affecting
P.A., or any of the Assets to be conveyed  hereunder,  and to the best knowledge
of P.A., Dr. Herman and Dr. Pazandak there is no basis for any of the foregoing.

      VI.4 LICENSES.  SCHEDULE 6.4 is a list of all material licenses,  permits,
authorizations, approvals and consents (collectively, the "Licenses") P.A. owns,
uses, or has obtained relative to operating or conducting P.A.'s business. There
are no other material licenses, permits,  authorizations,  approvals or consents
required by any federal,  state, or local  government or government  department,
agency,   board,   commission,   bureau   or   instrumentality    (collectively,
"Governmental  Authority") to properly  operate or conduct the P.A.'s  business.
Each license has been duly  obtained as valid and in full force and effect,  and
is not subject to any pending or, to the best  knowledge of P.A., Dr. Herman and
Dr. Pazandak, threatened administrative or judicial proceeding to revoke, cancel
or declare such license  invalid in any respect.  To the best knowledge of P.A.,
Dr. Herman and Dr. Pazandak, P.A. is not in default or in violation with respect
to any of the licenses, and no event has occurred which constitutes, or with due
notice or lapse of time or both may  constitute,  a default  by P.A.  under,  or
violation of, any license. P.A. has completed and submitted,  on a timely basis,
all reports and filings  associated  with the P.A.'s business as are required by
any governmental authority. P.A. will take all necessary actions to transfer, or

its designee.

      VI.5 TANGIBLE  PERSONAL  PROPERTY.  The machinery,  equipment,  furniture,
fixtures,  office  supplies,  warranty  rights,  supplies,  books  and  records,
(excluding medical records),  and other tangible personal property owned, leased
or used by P.A. (the "Tangible  Personal  Property") are sufficient and adequate
to  permit  P.A.  to  conduct  the  P.A.'s  business  as it is  presently  being
conducted,  and P.A.  has not  received  notice  that any such item of  Tangible
Personal  Property or the use thereof is in violation of any existing law or any
building, zoning, health, safety or other ordinance, code or regulation. P.A. is
not in default with respect to any item of Tangible Personal Property  purported
to be leased by it, and no event has  occurred  which  constitutes,  or with due
notice or lapse of time or both may constitute,  a default under any such lease.

Personal  Property  of any other  person,  firm or  corporation  pursuant to any
consignment or similar arrangement.

United  States  and  state  trademarks,   servicemarks,  trade  names,  patents,
copyrights,  trade secrets,  technical  data and  proprietary  know-how  (either

used in the business of P.A. (the "Intangible Property"). Such a list includes a
summary description of each such item and specifies,  where applicable, the date
the license or registration  was granted or applied for, the expiration date and
the current status thereof.  There is no restriction effecting the use of any of
the  Intangible  Property by P.A.  and no license has been  granted with respect
thereto.  Each item of Intangible Property is valid and in good standing, is not
currently  being  challenged  or  infringed,  is not  involved in any pending or
threatened administrative or judicial proceeding, and does not conflict with any
rights of any other person,  firm or corporation.  Other than listed on SCHEDULE
6.6.2,  P.A. has only  operated or  transacted  business  under the name of ECSC
Retina, P.A.

      VI.7 CONTRACTS OR OTHER  AGREEMENTS.  P.A. has described on SCHEDULE 6.7.1
and has  furnished  to Omega  North  Texas  copies  and/or  descriptions  of all
Contracts or Other  Agreements  affecting  the Assets.  P.A. has  performed  all
obligations  required of P.A.  with respect to, and except as listed on SCHEDULE
6.7.2,  P.A. is not in default under,  any such  Contracts or Other  Agreements.
Except as listed on SCHEDULE  6.7.3,  neither the  execution nor the delivery of
this Agreement,  nor the  consummation of the transactions  contemplated  hereby
will:  (i) conflict with,  constitute a breach,  violation or termination of any
provision of any  Contracts or Other  Agreements  to which P.A. is a party or by
which P.A. is bound;  (ii)  result in the  creation  or  imposition  of any lien
against any of the Assets;  or (iii) to the best  knowledge of P.A.,  Dr. Herman
and Dr.  Pazandak  after  due  inquiry  by each,  violate  any law,  regulation,
judgment,  rule, order or any other material restriction  applicable to the P.A.
or the Assets.

      VI.8 FUTURE  BILLING.  To the extent  permitted  by  applicable  law,  Dr.
Herman,  Dr. Pazandak,  and P.A. hereby appoint Omega North Texas as their agent
to bill,  collect and otherwise seek payment for professional  services rendered
by Dr.  Matthews,  or any  related  entity;  provided,  however,  to the  extent
permitted by applicable law, such appointment may, upon thirty (30) days written

                                     - 33 -

notice to Omega North  Texas,  be revoked by any of Dr.  Herman,  Dr.  Pazandak,
P.A.,  or any related  entity for the purpose of enforcing  any  indemnification

controlled by Dr. Herman or Dr. Pazandak.

      VI.9  HEALTHCARE  COMPLIANCE.   P.A.  is  participating  in  or  otherwise
authorized to receive  reimbursement  from or is a party to Medicare,  Medicaid,
and other third-party payor programs. All necessary certifications and contracts
required  for  participation  in such  programs are in full force and effect and
have not been amended or otherwise modified,  rescinded,  revoked or assigned as
of the date  hereof,  and to the best  knowledge  of P.A.,  Dr.  Herman  and Dr.
Pazandak,  no condition exists or event has occurred which in itself or with the
giving of notice or the lapse of time or both  would  result in the  suspension,
revocation, impairment, forfeiture, or non-renewal of any such third-party payor
program. To the best knowledge of P.A., Dr. Herman and Dr. Pazandak,  P.A. is in
full compliance with the  requirements  of all such  third-party  payor programs
applicable thereto.

      VI.10  FRAUD  AND  ABUSE.   P.A.  and  persons  and   entities   providing
professional  services for P.A.,  have not, to the  knowledge of P.A., or to the

own behalf or on behalf of  another,  with  intent to  fraudulently  secure such
benefit or payment; or

      (d)  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 or receive such remuneration (i)

contained  herein,  no representation or warranty made by P.A. in this Agreement
contains or will  contain any untrue  statement  of a material  fact or omits or

and SECTION 3.3, may not be sold,  transferred  or otherwise  disposed of absent
such  registration,  or unless an exemption from registration is available.  The
P.A. is acquiring the Omega Stock for its own account,  for investment  purposes
only and not with a view to  distribution of such Omega Stock within the meaning
of Section 2(11) of the  Securities  Act. Each of the  shareholders  of the P.A.

opportunity to obtain other additional  information  concerning Omega from Omega
senior management.

      VI.16  FINANCIAL   INFORMATION.   Attached  hereto  as  SCHEDULE  6.16  is
certain financial  information  relating to the P.A. for its operations  through
July 31, 1996. Such financial  information fairly reflects results of operations

acceptable candidate will be selected by the American  Arbitration  Association.

have selected an  arbitrator.  The results of the  arbitrator's  finding will be
binding on the parties.

SECTION 2.  MANAGEMENT SERVICE AND OTHER FEES.

      2.1 ECSC and  Manager  hereby  mutually  recognize  and  acknowledge  that
Manager will incur  substantial  costs in arranging for ECSC's use of the Center
and in providing  the office space,  support  services,  personnel,  management,
administration  and other items and services that are the subject matter of this
Agreement.  As  compensation  for  services  rendered  under  the  terms of this
Agreement,  and subject to the  conditions  set forth  below,  ECSC shall pay to
Manager a fee of $42,333.00 per month (the "Service  Fee");  provided,  however,
with respect to any month  during which this  Agreement is not in effect for the
entirety of such  month,  the Service Fee for such month shall be reduced at the
rate of  $1,411.10  for each day of such  month  that this  Agreement  is not in
effect. Such fee is acknowledged as the parties' negotiated  agreement as to the
reasonable  fair market value of the  equipment,  support  services,  personnel,
office space, management,  administration and other items and services furnished
by Manager pursuant to this Agreement,  considering the nature and volume of the
services required and the risks assumed by Manager.

        2.2 (a) In  addition to the  Service  Fee,  ECSC shall pay to Manager an
"Administration Fee" (as hereinafter  defined).  ECSC and Manager recognize that
certain of such costs and expenses may vary to a considerable  degree  according
to the extent of ECSC's  business and  services.  Furthermore,  ECSC and Manager
agree that it will be  impracticable to ascertain and segregate all of the exact
costs  and  expenses  that  will be  incurred  by  Manager  from time to time in
performance of its obligations under this Agreement.  However,  it is the intent
of the parties that the  Administration  Fee paid to Manager (as  calculated  in
SECTION 2.3 herein)  shall reflect the risk taken by Manager and an incentive to
Manager to enhance the cost effectiveness of ECSC's operations .

      (b)  Payment of the  Administration  Fee is not  intended  to be and shall
neither be interpreted or applied as permitting  Manager to share in ECSC's fees
for medical services or any other services, nor shall such fee be interpreted as
being paid in whole or in part for referrals of any kind whatsoever.

      2.3  (a)  Manager  shall  be  entitled  to  an  administration   fee  (the
"Administration  Fee") on a monthly basis equal to  twenty-six  percent (26%) of
the amount by which and after the time the "Gross  Collections"  (as hereinafter
defined) of ECSC exceed  $3,640,000  (the "Base Amount") each and every calendar
year during the term of this Agreement; provided further, the Administration Fee
to which Manager is entitled for the calendar year 1996 shall be calculated only
from the  effective  date of this  Agreement and shall not take into account any
amount of Gross  Collections  of ECSC prior to such  effective  date;  provided,
however,  the  Administration  Fee for  1996  shall  be  pro-rated  based on the
percentage  of the calendar  year  involved as a percentage  of the Base Amount;
provided further,  however,  the Administration Fee to which Manager is entitled
for the calendar year during which this Agreement terminates  (regardless of the
reason for such  termination)  shall not take into  account  any amount of Gross
Collections subsequent to the date of termination.







                                     - 50 -


<PAGE>

      (b)  On May 1,  1998,  the  parties  agree  to  review  the  adequacy  and
appropriatness of the  Administration  Fee and to adjust such fee based upon the
facts and  circumstances  then  existing.  In the event the parties cannot agree
upon an  appropriate  adjustment,  the  parties  agree to submit  the  matter to
arbitration,  and the costs of such  arbitration  shall be borne  equally by the
parties. Thereafter, the parties agree to a similar annual review beginning each
May 1 thereafter during the term of this Agreement.

      2.4 As a result of ECSC's licensed use of the Marks (as "Marks" is defined
in SECTION 19  hereof),  Manager  shall be paid a License Fee of  $1,000.00  per
month; provided,  however, with respect to any month during which this Agreement
is not in effect  for the  entirety  of such  month,  the  License  Fee shall be
reduced at the rate of $33.00 for each day of such month that this  Agreement is
not in effect.

      2.5 The  compensation  provided  to  Manager  under this  Agreement  shall
constitute  full  compensation  for all services  rendered by Manager under this
Agreement,  and no further  compensation  shall be due.  Manager  shall not seek
additional  compensation  from any  source  for  services  rendered  under  this
Agreement.  Except as otherwise  specifically  provided  for in this  Agreement,
amounts  delivered or required to be  delivered to ECSC  pursuant to SECTION 2.6
hereof shall  constitute  the only amount that Manager is required to deliver to
ECSC under this  Agreement;  and ECSC shall not seek the  payment of  additional
amounts from any other source for medical services rendered by ECSC.

      2.6 On the  first  (1st)  day of  each  month  during  the  term  of  this
Agreement,  Manager  shall  be paid the  Service  Fee and the  License  Fee with
respect to the immediately  preceding month (the "Month in Question").  No later
than the twentieth  (20th) day of each month during the term of this  Agreement,
Manager shall be paid the  Administration Fee (if any) with respect to the Month
in Question.  No later than the twentieth (20th) day of each month Manager shall
deliver  to ECSC  an  amount  equal  to the  difference  between  (a) the  Gross
Collections  during the Month in  Question,  minus (b) the sum of (i) the Direct
Operating Expenses (hereinafter defined) paid during the Month in Question,  and
(ii) a  reasonable  reserve,  not  exceeding  ten  percent  (10%) of the  Direct
Operating  Expenses for the Month in Question,  to pay Direct Operating Expenses
subsequent to the Month in Question.

      2.7 For purposes of this Agreement,  the term "Direct Operating  Expenses"
shall mean all costs and  expenses of the Center,  computed in  accordance  with
generally  accepted  accounting  principles  using a cash method of  accounting,
including,  but not be limited to, all employees and support staff  salaries and
benefits,  compensation  for doctors  employed by ECSC (other than Dr. Wesley K.
Herman ("Dr.  Herman") and Dr.  Bradford B. Pazandak  ("Dr.  Pazandak")),  rent,
office and medical supplies and tools,  taxes (including  interest and penalties
thereon), health insurance,  malpractice insurance, amounts paid in satisfaction
of malpractice claims not reimbursed by insurance,  general liability  insurance
(including  extended  (umbrella)  coverage),   disability  insurance,  marketing
expenses, interest expenses, utilities, maintenance, general and hazardous waste
disposal,  "Expense Account Items" (as hereinafter  defined),  rentals,  leases,
depreciation and amortization of leasehold improvements, furniture, fixtures and
equipment, other fixed assets, and intangibles purchased after the Closing Date,


                                     - 51 -


<PAGE>

and the License Fee, the Service Fee and the Administration Fee, if any, paid to
Manager  under this  Agreement.  The  amount of  depreciation  and  amortization
included in Direct Operating Expenses shall relate only to those assets acquired
by ECSC after August 31, 1996,  and shall be based upon a five (5) year life for
such assets  computed  on a  straight-line  method.  The  corporate  overhead of
Manager,  beyond the Service Fee,  Administration Fee, and License Fee shall not
be included as a Direct Operating Expense.

      2.8 For purposes of this  Agreement,  the term "Gross  Collections"  shall
mean all revenues  attributable to medical  services and other related  services
rendered  on or after  September  1, 1996 by the Center  and/or  its  employees,
computed in accordance with generally  accepted  accounting  principles  using a
cash method of  accounting,  less (i) all refunds  paid,  and (ii) any amount(s)
paid toward the  satisfaction  of the  insurance  deductible  applicable  to the
defense of any medical  malpractice  claim made against the Center,  ECSC or its
employees.   Gross  Collections   shall  not  include  loan  proceeds,   capital
contributions,  casualty insurance  proceeds,  proceeds from sale of assets, and
any other extraordinary payments received not relating to the normal business of
ECSC.

      2.9 Manager shall have the  responsibility  for billing and collecting for
services  provided by ECSC.  Except as  provided  for in the last  paragraph  of
SECTION 12 hereof,  and to the extent  permitted by  applicable  law, ECSC shall
have no right to receive, nor shall ECSC attempt to bill for or collect, payment
from the  patient  or any  third  party  for  services  provided  by ECSC.  ECSC
acknowledges that Manager has the sole right of and  responsibility  for billing
and collecting for services provided by ECSC;  however,  ECSC shall be consulted
on all bad debt write offs,  courtesy discounts and collection agency referrals.
Notwithstanding  the  foregoing,  ECSC  does not  assign  any sums or  rights of
payment for which assignment is prohibited by law.

      2.10 ECSC shall  establish,  and Manager shall  jointly agree upon,  fees,
charges and appropriate  diagnosis codes,  procedure codes and billing codes for
all  services  provided  under  this  Agreement.  In all  cases,  fees  shall be
competitive  with fees for similar  services  by others in the Service  Area (as
hereinafter defined); provided, however, ECSC shall not be required to incur any
cost or expense to determine whether its fees are competitive as described, and,

SECTION 3.  RESPONSIBILITIES.

      3.1 During the Term of this  Agreement,  Manager  shall  provide  all such
management,  administrative,  financial,  fiscal, management information system,
and  business  services as are  reasonably  necessary  and  appropriate  for the
day-to-day  administration  of the  business  aspects of ECSC's  operations,  in
accordance with the law and all rules,  regulations and guidelines of applicable
governmental agencies.

      3.2 (a) Manager shall employ or otherwise  retain and shall be responsible
for  selecting,   training,   supervising,   and   terminating  all  management,
administrative, clerical, secretarial, bookkeeping, accounting, payroll, billing
and collection  and other  personnel as Manager deems  reasonably  necessary and
appropriate for Manager's  performance of its duties and obligations  under this
Agreement.  Manager  specifically  agrees to provide one  full-time  employee to
serve as Center  Director  of ECSC on such  terms as  determined  by  Manager in
consultation  with ECSC and  officed  in  Dallas,  Texas.  As part of  Manager's
staffing  obligations,  Manager shall be solely  responsible for determining the
salaries and fringe benefits of the above-described  employees,  for paying such
salaries and providing such fringe benefits, for withholding as required by law,
any sums of income tax,  unemployment  insurance,  social  security or any other
withholding  pursuant to any applicable  law or  governmental  requirement,  for
determining  bonuses for such employees and for providing worker's  compensation
insurance for all of the above-described  employees.  In recognition of the fact
that  management  personnel  provided to ECSC under this  Agreement  may perform
similar services from time to time for others,  this Agreement shall not prevent
Manager from  performing  such similar  services for others or restrict  Manager
from using the personnel  provided to ECSC under this  Agreement to provide such
services  to  others.  Manager  will make  every  effort  consistent  with sound
business  practices  to honor the  specific  requests of ECSC with regard to the
assignment  of  Manager's  employees  but  Manager  reserves  the sole  right to
determine the assignment of its employees.  Manager shall be responsible for any
appropriate  disciplinary  action  required  to be  taken  against  any  of  the
above-described staff personnel.

      (b)  Manager  shall have sole  responsibility  for  administering  payroll
services,  providing any fringe  benefits,  withholding any sums for income tax,
unemployment insurance,  social security as required by law, and withholding any
other sums required by applicable law or governmental requirement. Manager shall
have sole  responsibility  for preparing,  maintaining  and filing all requisite
reports  and  statements   regarding  income  tax   withholdings,   unemployment
insurance,  social security, equal employment opportunity,  or other reports and
statements  required by law with respect to personnel  provided by Manager under
this Agreement.

      (c) In  recognition  of the  fact  that  Manager  and the  management  and
administrative  personnel provided to ECSC by Manager pursuant to this Agreement
may from time to time perform  services  for others,  this  Agreement  shall not
prevent  Manager  or such  personnel  from  performing  services  for  others or
restrict  Manager from so using Manager's  personnel.  Manager reserves the sole
right to determine the assignment of its personnel.

      3.3 The parties acknowledge and agree that the rights, powers, duties, and
responsibilities  of ECSC and  Manager  may be  limited by  applicable  federal,
state, and local laws and regulations  affecting the operation of the Center and
the  services  provided at the Center.  ECSC and Manager  agree to and intend to
comply fully with such  applicable  laws and  regulations in the  performance of
their respective responsibilities.

      3.4 ECSC is  responsible  for the  quality of medical  and  surgical  care
rendered at the Center and, therefore, retains full authority concerning medical
and  ethical  matters  that arise  within and in  relation  to ECSC's  practice.
Manager and ECSC shall  perform  their  obligations  under this  Agreement  in a
manner consistent with ECSC's responsibility for patient care.

      3.5 ECSC shall be responsible for hiring  additional  ophthalmologists  as
needed to accommodate patient volume.

      3.6 ECSC  and its  licensed  ophthalmologists  shall  be  responsible  for
encouraging  and  providing  quality  patient  care and  developing  a  positive
professional  relationship with other health care professionals  involved in the
care of  patients  treated  at the  Center,  including,  where  appropriate  and
consistent with law,  facilitating  co-management  of patients under the primary
care of practitioners practicing independently of the Center.

      3.7 ECSC shall seek to secure any licenses  that are needed to operate the
Center, as well as accreditation or certification by Medicare,  Medicaid, JCAHO,
and other organizations, as appropriate.

      3.8 ECSC shall  acquire and  maintain at all times during the term of this
Agreement,  professional liability insurance coverage, subject to exclusions and
deductibles  included in such  policies.  All such policies are to be written or
amended to include  Manager as an additional  named insured.  Evidence of ECSC's
insurance  coverage  shall  be  supplied  to  Manager  upon  execution  of  this
Agreement,  and at any time thereafter upon request, and such insurance coverage
shall (a) be paid as a Direct Operating Expense of the Center,  (b) have minimum
limits of $1,000,000 per occurrence,  $3,000,000  annual  aggregate,  and (c) be
provided through insurers acceptable to ECSC and Manager. Any investigational or
other care provided by ECSC and not covered by professional  liability insurance
coverage may be undertaken  with the approval of Manager,  which  approval shall
not be unreasonably withheld.

      3.9 ECSC  shall  review  and  consult  with  Manager  in the  location  of
additional facilities,  selection of equipment and other key activities relating
to the growth of the Center.  Notwithstanding the foregoing, however, nothing in
this SECTION 3.9 shall be construed to include (i) those medical  decisions that
are  the  sole  responsibility  of ECSC or  (ii)  those  non-medical  decisions,
described in this Agreement that are the sole responsibility of Manager.

      3.10  ECSC  and  its  licensed   ophthalmologists   shall  participate  in
continuing  education  programs sponsored by the Center for the benefit of local
health care professionals, including formal and informal educational activities,

                                     - 54 -


<PAGE>

observation  of medical  management of patients and, when in the opinion of ECSC
it is appropriate and consistent with applicable law and good surgical practice,
observation  of surgical  procedures.  Such licensed  ophthalmologists  may also
participate in ophthalmology training programs so long as Manager is notified in
advance and scheduling conflicts are resolved.

      3.11 Manager  shall employ a Center  Director.  The Center  Director  will
oversee all business and financial activities of the Center and communicate with
Manager all business  activities  and/or financial  information  relative to the
Center as required by Manager.  The Center  Director  will also  provide  direct
patient care to patients of the Center on a limited basis. In addition,  Manager
shall employ an Administrator for the Center.  The  Administrator  will directly
manage the day-to-day  operations of the Center,  including fiscal monitoring of
the Center, in-house accounting for the Center, and personnel management for the
Center.  The Center Director and the Administrator  will be jointly  responsible
for the Center's strategic planning, financial management,  budgeting,  business
operations,  marketing  activities,  personnel  training,  and development.  The
Administrator will report to the Center Director.

      3.12 ECSC shall provide and arrange for  professional  ophthalmic  medical
services at the Center  including,  without  limitation,  secondary and tertiary
medical and surgical eye care services,  on a full-time  basis.  "Full-time," as
that term is used in this Agreement,  refers to twenty-four  (24) hours per day,
seven (7) days per week, as patient  demand  warrants.  On call services will be
provided or arranged by ECSC.  Leave time and coverage shall be jointly arranged
by ECSC and Manager  consistent with the terms of this Agreement and, except for
death,  illness,  injury,  family  tragedy,  or as required under the Family and
Medical Leave Act, as amended,  if applicable,  or other applicable law, neither
Dr. Herman nor Dr.  Pazandak shall be away from the Center for more than fifteen
(15)  consecutive  business  days  unless  agreed  upon by both  the  applicable
physician and Manager.  Except as otherwise  provided in this SECTION 3.12, each
of Dr.  Herman and Dr.  Pazandak  will work at the Center  (which also  includes
professional  services at other  locations as necessitated by patient care needs
or availability  of equipment and technology) for at least two hundred  thirteen
(213) days (the "Required  Work Days") during the "Calendar  Year." For purposes
of this  SECTION  3.12,  "Calendar  Year"  means the twelve  (12)  month  period
beginning January 1 of each year and ending at the close of business on December
31 of each year.  For periods less than a full Calendar  Year, the Required Work
Days will be prorated  accordingly.  In the event that either Dr.  Herman or Dr.
Pazandak works over the Required Work Days in any Calendar  Year,  then any such
days, up to a maximum of five (5) days annually, may be carried over to the next
Calendar  Year for the  benefit  of such  person.  ECSC and Dr.  Herman  and Dr.
Pazandak agree, subject to family commitments and other personal considerations,
to use their best efforts to have either Dr. Herman or Dr. Pazandak available to
the Center for  professional  services or  consultation  during normal  business
hours.  Notwithstanding  the  foregoing,  nothing in this  SECTION 3.12 shall be
construed  to  require  either Dr.  Herman or Dr.  Pazandak  to perform  primary
eyecare services.  In addition,  Dr. Herman and Dr. Pazandak shall be allowed to
continue  their work with Insight  International,  Inc.,  a Delaware  non-stock,
non-profit corporation ("Insight International").

      3.13  During  the  term  of  this  Agreement,  Manager  agrees,  upon  the
presentation of a premium invoice or evidence of an automated bank draft premium
transaction,  to  promptly  reimburse  ECSC  for the  cost of  acquiring  and/or
maintaining a $250,000 term life insurance  policy on the life of Dr. Herman and
a $250,000  term life  insurance  policy on the life of Dr.  Pazandak (the "Life
Insurance Policies"). Each of the Life Insurance Policies shall be owned by ECSC
but Dr.  Herman shall have the right to designate  the  beneficiary  of the Life
Insurance  Policy  insuring  his life and Dr.  Pazandak  shall have the right to
designate  the  beneficiary  of the Life  Insurance  Policy  insuring  his life.
Nothing in this  SECTION  3.3 shall  preclude  or prevent  ECSC from  assigning,
cancelling or otherwise  terminating one or both of the Life Insurance Policies,
and acquiring another Life Insurance Policy to replace the Life Insurance Policy
so  assigned,  cancelled  or otherwise  terminated;  likewise,  ECSC may assign,
cancel or otherwise  terminate  one or both of the Life  Insurance  Policies and
elect,  in its sole  direction,  not to replace the Life  Insurance  Policies so
assigned, cancelled or otherwise terminated. The cost of acquiring,  maintaining
and replacing the Life Insurance Policies shall be a Direct Operating Expense of
the  Center.  ECSC  shall  provide  Manager  with a copy of the  Life  Insurance
Policies in effect as they exist from time to time.

      3.14  During the term of this  Agreement,  Manager  shall be  entitled  to
obtain,  at  Manager's  sole  cost and  expense,  one or more  policies  of life
insurance on the lives of Dr. Herman and Dr.  Pazandak  naming  Manager,  to the
extent  permitted by applicable law, as beneficiary  (the "Key Man  Insurance").
Dr. Herman and Dr. Pazandak shall cooperate as is reasonably necessary to assist
Manager in  obtaining  the Key Man  Insurance,  including,  but not  limited to,
providing  authorization  for release to the insurance company of the respective
medical  records  of each  and  submitting  to  medical  examinations  as may be
reasonably  required by the insurance  company.  If either or both of Dr. Herman
and Dr.  Pazandak  are, for any reason,  determined to be  uninsurable,  neither
ECSC, Dr. Herman nor Dr. Pazandak shall have any liability or  responsibility to
Manager or to any other person or entity for  Manager's  failure or inability to
obtain the Key Man Insurance.

      3.15  During  the  term  of  this  Agreement,  Manager  agrees,  upon  the
presentation of a premium invoice or evidence of an automated bank draft premium
transaction, to promptly reimburse ECSC for the cost, not to exceed Ten Thousand
Dollars ($10,000) annually, of acquiring and/or maintaining an income disability
insurance  policy with Dr. Herman as the named insured and an income  disability
insurance  policy  with Dr.  Pazandak  as the  named  insured  (the  "Disability
Policies").  Each of the  Disability  Policies  shall be owned by ECSC,  but Dr.
Herman  shall have the right to  designate  the  beneficiary  of his  Disability
Policy and Dr. Pazandak shall have the right to designate the beneficiary of his
Disability  Policy.  Nothing in this SECTION 3.15 shall preclude or prevent ECSC
from  assigning,  cancelling  or  otherwise  terminating  one  or  both  of  the
Disability  Policies  and  acquiring  another  Disability  Policy to replace the
Disability Policy so assigned, cancelled or otherwise terminated; likewise, ECSC
may assign, cancel or otherwise terminate one or both of the Disability Policies
and elect,  in its sole  discretion,  not to replace  the  Disability  Policy so
assigned, cancelled or otherwise terminated. The cost of acquiring,  maintaining
and/or replacing the Disability  Policies shall be a Direct Operating Expense of
the Center. ECSC shall provide Manager with a copy of the Disability Policies in
effect as they exist from time to time.

<PAGE>

      3.16 During the term of this Agreement,  Manager agrees that ECSC shall be
paid Five  Thousand  Dollars  ($5,000) per month for each of Dr.  Herman and Dr.
Pazandak  (i.e.,  $10,000 per month in the aggregate) for certain  discretionary
costs and expenses  specifically  designated  by ECSC as  discretionary  expense
account  items (the  "Expense  Account  Items").  Expense  Account  Items  shall
include, but not be limited to, professional dues,  subscriptions,  licenses and
memberships  in  professional   organizations   and   professional   activities,
continuing  education expenses (including all travel,  meals and lodging related
thereto),  entertainment and related expenses  (including all travel,  meals and
lodging related  thereto) and such other costs and expenses deemed by Dr. Herman
or Dr.  Pazandak to be Expense  Account  Items.  Expense  Account Items shall be
included as a Direct Operating Expense of the Center.

SECTION 4.  GENERAL COVENANTS.

      4.1 ECSC and  Manager  are  independent  legal  entities.  Except  for the
principal and agent  relationship  created  under SECTION 12 hereof,  nothing in
this  Agreement  shall be construed to create the  relationship  of employer and
employee,  joint venturers,  partnership or any relationship  other than that of
independent  parties  contracting  with each other  solely for the  purposes  of
carrying  out the terms of this  Agreement.  Neither ECSC nor Manager nor any of
their respective  agents or employees shall control or have any right to control
the manner and means by which the other party carries out its obligations  under
this Agreement,  nor shall either party, its respective agents or employees,  be
liable  to  third  parties  for any act or  omission  of the  other  party.  The
professional responsibility to patients for the delivery of medical and surgical
services  under this  Agreement  shall at all times  remain with ECSC,  and ECSC
shall be expected to exercise independent  professional  judgment in the conduct
of any and all activities which may reasonably be considered as constituting the
practice of medicine.  Neither  Manager nor any of its employees or agents shall
in any way interfere with the professional  judgment of ECSC in the provision of
professional  medical services.  Each party further  understands and agrees that
(i) the other will not be treated as an employee for federal tax purposes;  (ii)
neither  will  withhold  on  behalf  of the  other  any  sums  for  income  tax,
unemployment  insurance,  social security,  or any other withholding pursuant to
any law or  requirement  of any  governmental  body or make available any of the
benefits  afforded to its employees;  (iii) all of such payments,  withholdings,
and benefits,  if any, are the sole  responsibility  of the party  incurring the
liability; and (iv) each will indemnify and hold harmless the other from any and
all loss or  liability  arising with respect to such  payments,  withholds,  and
benefits, if any.

      4.2 Except as provided in SECTION 2 of this  Agreement,  all the costs and
expenses  of  providing,  maintaining,  repairing  and  operating  the  Center's
physical plant, shall be Direct Operating Expenses of the Center.

      4.3 (a) Manager  shall  indemnify and hold  harmless  ECSC,  its officers,
directors and employees  from and against any and all liability,  loss,  damage,
claims,  causes of action, costs and expenses (including  reasonable  attorneys'
fees), whether or not covered by insurance,  caused, directly or indirectly,  by
or as a result of the  performance  of any acts or omissions  by Manager  and/or

                                     - 57 -

<PAGE>

Manager's shareholder or agents, employees and/or subcontractors during the term
hereof.  ECSC agrees to give prompt  notice to Manager of the  assertion  of any
claim, or the threat or commencement  of any suit,  action,  proceeding or other
matter in respect of which  indemnity  may be sought under this SECTION  4.3(A).
Manager may participate in the defense of any such suit,  action,  proceeding or
other  matter at  Manager's  expense.  Manager  shall not be liable  under  this
SECTION  4.3(A) for any settlement  effected  without  Manager's  consent of any
claim,  suit,  action,  proceeding or other matter in respect of which indemnity
may be sought under this SECTION 4.3(A), which consent shall not be unreasonably
withheld.  Should  Manager refuse to pay any indemnity  obligation  owed to ECSC
under this SECTION 4.3(A) within the thirty (30) day cure period provided for in
SECTION  6.1  hereof,  ECSC may (i)  revoke  its  appointment  of Manager as its
attorney-in-fact  pursuant  to SECTION 12 hereof and (ii)  withhold  the Service
Fee, the  Administration Fee and the License Fee owed to Manager under SECTION 2
of this Agreement,  until such time as Manager has paid to ECSC any amounts owed
under this SECTION 4.3(A).

      (b) ECSC shall  indemnify,  hold  harmless and defend  Manager,  Manager's
officers, directors and employees, from and against any and all liability, loss,
damage,  claims,  causes of action,  costs, and expenses  (including  reasonable
attorneys'  fees),  caused,  directly  or  indirectly,  by or as a result of the
performance of any intentional acts,  negligent acts or omissions by ECSC and/or
its shareholders,  agents,  employees and/or subcontractors (other than Manager)
during the term of this Agreement.  Manager agrees to give prompt notice to ECSC
of the  assertion  of any  claim,  or the  threat or  commencement  of any suit,
action,  proceeding or other matter in respect of which  indemnity may be sought
under this SECTION 4.3(B). ECSC may participate in the defense of any such suit,
action,  proceeding or other matter at ECSC's expense.  ECSC shall not be liable
under this SECTION 4.3(B) for any settlement  effected without ECSC's consent of
any  claim,  suit,  action,  proceeding  or other  matter  in  respect  of which
indemnity  may be sought under this SECTION  4.3(B),  which consent shall not be
unreasonably withheld.

SECTION 5.  TERM.

      This Agreement shall become  effective August 31, 1996, shall continue for
a term ending  August 30, 2021 (the  "Initial  Term"),  and shall  automatically
renew thereafter for consecutive  terms of three (3) years each (the "Subsequent
Term"),  unless and until (i) terminated pursuant to SECTION 6 of this Agreement
or (ii) unless and until either party gives one hundred eighty (180) days notice
of an  intent  to  terminate  this  Agreement  prior  to the  expiration  of any
Subsequent Term.

SECTION 6.  DEFAULTS OR TERMINATION.

      6.1 Either party shall be entitled to terminate this Agreement immediately
on written notice to the other party in the event of the failure of either party
to pay the other any undisputed  amount payable pursuant to this Agreement for a
period of thirty (30) days after such undisputed  amount is due.  Declaration of
default and termination  shall not excuse the defaulting party of any obligation
for  payments  due  hereunder  for  services  rendered  prior  to  the  date  of
termination.

      quality of patient care provided at the Center.

      6.3 Manager  shall be entitled to terminate  this  Agreement on sixty (60)
days  written  notice  to ECSC of any of the  following  events  (excluding  any
payment  default as provided for in SECTION 6.1) and the failure of ECSC to cure
any such matter during such notice period:

      (a) any act or omission on the part of ECSC which  jeopardizes the quality
      and delivery of patient care;

      (b) the  failure  of ECSC to  perform,  keep or  fulfill  any of the other
      covenants,  undertakings,  obligations  or  conditions  set  forth in this
      Agreement; or

      (c) any act of ECSC involving dishonesty, moral turpitude or disloyalty to
      the Center.

      6.4 Upon  notification  by the  appropriate  authority,  and  pursuant  to
SECTION 14.2 of those certain Employment  Agreements by and between ECSC and Dr.
Herman  and ECSC and Dr.  Pazandak  (the  "Employment  Agreements"),  ECSC shall
immediately  terminate  the  Employment  Agreement of the  offending  party upon
written notice to ECSC that Dr. Herman or Dr.  Pazandak is the subject of any of
the following:

      (a) revocation,  termination,  a material restriction,  or a suspension of
      either Dr. Herman's or Dr. Pazandak's  license to practice medicine in the
      State of Texas, subject to no further administrative or judicial process;

      (b) revocation,  termination,  a material restriction,  or a suspension of

      relinquishment of such privileges to avoid disciplinary action, subject to
      no further administrative or judicial process;

      (d) exclusion from  participation  in Medicare,  Medicaid or other similar
      government program;





                                     - 59 -


<PAGE>

      (e)  inability to obtain professional liability insurance coverage;

      (f) a finding by any court,  governmental  agency, or professional society
      of  unprofessional  or illegal conduct by ECSC, Dr. Herman or Dr. Pazandak
      which materially  adversely  affects either Dr. Herman's or Dr. Pazandak's
      ability to perform the  obligations of a physician,  subject to no further
      administrative or judicial process;

      (g)  the conviction of a felony; or

      (h) the death or disability of Dr. Herman or Dr.  Pazandak.  Disability is
      here defined to mean the physical or mental inability of Dr. Herman or Dr.
      Pazandak  to  perform  for a period of ninety  (90)  consecutive  days the
      material  duties  of Dr.  Herman's  or Dr.  Pazandak's  occupation  or any
      covenant or duty of ECSC required by this Agreement.

      Manager's  failure  to  immediately  exercise  its  right  of  termination
hereunder shall not be deemed a waiver of its right to do so; provided, however,
the Manager's right of termination pursuant to this SECTION 6 shall survive only
ninety (90) days  following  Manager's  receipt of actual  notice of an event in
this Section.

      6.5 Upon any termination of this Agreement,  the Manager shall pay to ECSC
and ECSC shall pay to the  Manager  any  accrued  but unpaid sums due under this
Agreement  through the date of termination  such as  receivables  billed but not
collected at the time of termination.  Following the date of termination of this
Agreement, Manager will continue to use its best efforts to collect all accounts
receivable that existed as of the date of termination.

SECTION 7.  ARBITRATION AND MEDIATION.

      7.1 In the event a dispute arises out of or relating to this Agreement, or
the breach thereof,  and if said dispute cannot be settled through  negotiation,
the parties  agree to attempt in good faith to settle the  dispute by  mediation
under the Commercial  Mediation Rules of the American  Arbitration  Association.
Unless the parties reach an agreement reduced to writing, this mediation will be
non-binding,  but the  parties  must  participate  in good faith in  non-binding
mediation, before resorting to binding arbitration.

      7.2 Any controversy or claim arising out of or relating to this Agreement,
or its breach, not satisfied through either  negotiation or mediation,  shall be
settled by binding  arbitration in accordance  with the  Commercial  Arbitration
Rules of the American Arbitration Association.  Judgment upon the award rendered
by the arbitrator may be entered in any court having jurisdiction.

      As soon as reasonably  practical after  submission of a demand for binding
arbitration,  Manager and ECSC shall  select one  arbitrator,  agreeable  to all
parties.  This  arbitrator  will be selected from lists prepared by the American
Arbitration  Association.  From the American  Arbitration  Association list, the




                                     - 60 -


<PAGE>

parties will submit to the  American  Arbitration  Association  a ranked list of
arbitrators which are acceptable.  The highest ranking acceptable candidate will
be selected by the American Arbitration Association.  If no arbitrators from the
list composed by the American  Arbitration  Association are acceptable by either
of the parties, the American Arbitration Association will compile a second list.
This  procedure  will be followed until the parties have selected an arbitrator.
The results of the arbitrator's finding will be binding on the parties.

      7.3 The arbitration  and mediation  provisions in this Agreement shall not
apply to a suit instituted by Manager to enforce the provisions of those certain
Non-Competition  Agreement,  dated  as  of  August  31,  1996  (the  "Noncompete
Agreement")  with  Dr.  Herman  or Dr.  Pazandak,  respectively,  or  any  other
non-competition agreement with a licensed professional employed by ECSC.

SECTION 8.  RESTRICTIVE COVENANTS, CONFIDENTIALITY.

      8.1 The  parties  recognize  that the  services  to be provided by Manager
shall be  feasible  only if ECSC  operates an active  medical  practice to which
ECSC, Dr. Herman, Dr. Pazandak,  and any physicians  associated with ECSC devote
their  full time and  attention.  During  the term of this  Agreement  and for a
period of five (5) years following termination of this Agreement for any reason,
except a  termination  pursuant to SECTION 6.2, or a  termination  by ECSC under
SECTION 6.1, ECSC will not establish,  operate or provide  ophthalmic  physician
services at any medical office,  clinic or other health care facility  providing
services  substantially  similar to those  provided by Manager  pursuant to this
Agreement  anywhere  within the Service Area, as defined in SECTION 2.10 hereof.
Notwithstanding  the foregoing,  Dr. Herman and Dr. Pazandak shall be allowed to
continue their work with Insight International.

      8.2 ECSC and the Manager shall obtain and enforce written  agreements from
Dr.  Herman  and Dr.  Pazandak  and any other  physicians  associated  with ECSC
pursuant to which these  physicians  agree not to establish,  operate or provide
ophthalmic  physician  services at any  medical  office,  clinic or  out-patient
and/or  ambulatory   treatment  or  diagnostic   facility   providing   services
substantially  similar to those  provided by Manager  pursuant to this Agreement
within the Service Area and for a period of five (5) years after any termination
of their  respective  Employment  Agreements,  except a termination  pursuant to
SECTION 6.2, or a  termination  by ECSC under SECTION 6.1, ECSC shall obtain and
enforce formal written  agreements  from any future  physicians  associated with
ECSC as described in this SECTION 8.2.

      8.3 Except a termination  pursuant to SECTION 6.2 or a termination by ECSC
under  SECTION 6.1, and except for (i) those  entities  listed on SCHEDULE  8.3;
(ii) those entities in which Dr. Herman or Dr.  Pazandak own not more than a one
percent  (1%)  interest;  and (iii) the  practice of  ophthalmology  and related
activities by ECSC at the Center, during the term of their respective Employment
Agreements,  and for a period of five (5) years following a termination thereof,
neither  ECSC,  Dr.  Herman  or Dr.  Pazandak  will  engage in the  practice  of
ophthalmology,  either  directly or  indirectly,  actively or  passively,  under



                                     - 61 -

contract or  otherwise,  as an employee,  owner,  partner,  agent,  stockholder,
director,  or  otherwise,  within the Service  Area,  as defined in SECTION 2.10
hereof.

      8.4 In addition to, and separate from, the foregoing,  upon termination of
this  Agreement  (except  for  a  termination  pursuant  to  SECTION  6.2  or  a
termination  by ECSC under  SECTION 6.1, or a  termination  by Dr. Herman or Dr.
Pazandak pursuant to Section 14.3 of Dr. Herman's or Dr.  Pazandak's  respective
Employment  Agreement) and subject to the  limitations  set forth in SECTION 8.1
hereof,  ECSC will not,  within the Service Area:  (i) solicit for treatment any
person who has  received  medical  treatment  from ECSC  during the term of this
Agreement,  regardless  of whether  such person was treated by ECSC prior to the
effective date of this Agreement;  or (ii) offer employment to, solicit,  engage
by contract, or enter into any business relationship relating to the practice of
ophthalmology   with  any  person,   including   the  Center   Director  or  the
Administrator,  who is now or at any  time  during  the  term of this  Agreement
becomes an employee or service contractor of Manager. In the event ECSC employs,
engages by contract,  or enters into any business  relationship  not relating to
the practice of ophthalmology with any person,  including the Center Director or
the  Administrator,  who at that time is an  employee or service  contractor  of
Manager, ECSC shall give concurrent written notice of such action to Manager.

      8.5 ECSC understands and agrees that any breach of the covenants contained
in this SECTION 8 will cause irreparable injury and damages to Manager for which
there is no  adequate  remedy at law,  and as to which money  damages  cannot be
readily ascertained. Accordingly, ECSC consents in such event to the granting of
injunctive relief against any continuing breach, together with such other relief
available at law or equity.

      In the event Manager is granted  temporary  injunctive  relief as provided
herein,  whatever  portion of the five (5) year term (if  applicable)  stated in
SECTION  8.1 had not  expired at the time the  breach  first  occurred  shall be
tolled by the breach,  and shall begin to run again as of the first to occur of:
(i) the date the temporary injunctive relief expires or is withdrawn or (ii) the
date permanent  injunctive relief is granted.  If ECSC is found to have violated
the  covenants  of this SECTION 8, ECSC shall be liable to Manager for all costs
reasonably incurred by Manager in pursuing enforcement of the provisions of this
section,  including,  but not limited to,  reasonable  attorneys' fees and court
costs.

      8.6 The parties  acknowledge and agree that the provisions of this SECTION
8 have been specifically  bargained for, are reasonably necessary to protect the
legitimate business interests of Manager,  and shall survive termination of this
Agreement for any reason (except for a termination  pursuant to SECTION 6.2 or a
termination by ECSC under SECTION 6.1.).

      8.7  ECSC  acknowledges  that  as a  result  of the  business  arrangement
outlined in this  Agreement,  ECSC will learn  certain  proprietary  information
solely  through  its  relationship  with  Manager.   This  information  includes
information relating to billing procedures, patient lists, and other non-medical
patient records  constituting  proprietary  information which is the property of
Manager.  ECSC hereby agrees to protect the  confidentiality of this information
and consents to injunctive  relief and  liquidated  damages as described in this

                                     - 62 -


<PAGE>

SECTION  8, in the  event  ECSC  breaches  this  obligation.  Subject  to  those
disclosures  required by law, Manager agrees to protect the  confidentiality  of
any proprietary or other confidential  information Manager learns as a result of
its business arrangement with ECSC.  Notwithstanding the foregoing, it shall not
be a breach of this section for Manager to share  information  related to ECSC's
practice with  Manager's  Affiliates.  "Manager's  Affiliates"  shall mean Omega
Health  Systems,  Inc.,  a Delaware  corporation;  subsidiaries  of Manager;  or
subsidiaries of Omega Health Systems, Inc.

SECTION 9.  UTILIZATION MANAGEMENT; QUALITY ASSURANCE.

      ECSC shall  establish  a  utilization  management  and  quality  assurance
program to assure  the  appropriateness  and  quality of  services  rendered  to
patients at the Center.  Manager and ECSC mutually  agree to  participate in and
cooperate with such programs.

SECTION 10.  FURNITURE, FIXTURES, AND EQUIPMENT.

      All  furniture,  fixtures,  equipment,  and other  property  purchased  or
otherwise  provided by Manager to the Center  under the terms of this  Agreement
shall be and remain the property of Manager.  Upon any termination or expiration
of this  Agreement,  ECSC  shall be  entitled  to remove  and  retain  only such
furniture,  equipment,  and other  property  as shall have been  purchased  with
ECSC's own funds,  and shall have no claim or  property  interest  in any of the
furniture,  fixtures, or equipment provided by Manager. Any property provided by
ECSC and purchased with ECSC's own funds shall nevertheless become a part of the
premises,  and shall not be removed unless such property can be removed  without
substantial damage to the premises.

SECTION 11.  PATIENT FILES AND RECORDS.

      11.1  ECSC  and  Manager  shall  cooperate  fully in the  preparation  and
maintenance  of  appropriate  clinical  records with regard to all  professional
services  provided  by ECSC  under this  Agreement.  All such  records  shall be
maintained as a part of the clinical  records system in accordance  with prudent
record  keeping  procedures and as required by law. Both parties shall use their
best efforts to assure the adequacy of documentation  for professional  services
provided under this Agreement for third-party reimbursement purposes.

      11.2 In the event of (i) any  termination  or expiration of this Agreement
for any reason and (ii) the passage of forty-five  (45) days  following the date
upon which this Agreement  terminated or expired,  all clinical records prepared
and  maintained  pursuant  to this  Agreement  shall  remain in the custody of a
licensed  ophthalmologist approved by Manager, subject to applicable law. In the
event of any such termination or expiration,  and the subsequent transfer of any
records to such ophthalmologist,  ECSC, at its expense and upon written request,
shall be entitled to a copy of any and all such records  prepared and maintained
with regard to services rendered under this Agreement.

<PAGE>

      11.3 ECSC and  Manager  each agree to take all  necessary  precautions  to
prevent  the  unauthorized  disclosure  of  any  and  all  records  prepared  or
maintained under this Agreement and to keep such records confidential.

SECTION 12.  APPOINTMENT OF MANAGER AS ATTORNEY-IN-FACT.

      In  connection  with  Manager's  billing  and  collection   authority  and
responsibility and the discharge of its  responsibilities  under this Agreement,
and to the extent  permitted by applicable  law,  ECSC appoints  Manager for the
term hereof its true and lawful attorney-in-fact for the following purposes:

      (a)  To bill ECSC's patients in ECSC's name and on ECSC's behalf;

      (b)  To collect  accounts  receivable generated by such billings in ECSC's
name and on ECSC's behalf;

      (c)  To have access to ECSC's  designated  bank account for ECSC's medical
practice and to deposit in such account  collected  fees  generated  from ECSC's
medical  practice.  It is  expressly  understood  that the extent to which,  and
methods of which,  Manager will endeavor to collect such accounts,  the settling
of disputes  with  respect to charges and the writing off of charges that may be
or appear to be uncollectible  shall be mutually agreed upon in each instance by
ECSC and Manager.  Neither Manager's nor ECSC's decision in this regard shall be
unreasonably withheld or delayed. Manager does not guarantee the extent to which
any charges  billed will be collected.  Manager and ECSC shall consult with each
other prior to the institution of litigation to collect any account.  ECSC shall
initiate and be responsible for all such  litigation and the costs thereof.  All
costs of collection are a Direct Operating  Expense of the Center  regardless of
whether the collection is successful;

      (d) To receive payments from Blue Cross/Blue Shield,  insurance companies,
Medicare, Medicaid and all other third-party payers; and

      (e) To take  possession  of and  endorse  in the name of ECSC  any  notes,
checks, money orders,  insurance payments, and any other instruments received in
payment of the accounts receivable.

      To the extent  permitted by applicable  law, in the event of (i) a payment
default  under  SECTION 6.1 of this  Agreement (a "Payment  Default")  not cured
within the period  specified in SECTION 6.1, or (ii) a default under SECTION 6.2
of this  Agreement  ("Other  Default") not cured within the period  specified in
SECTION 6.2, ECSC's appointment of Manager as a true and lawful attorney-in-fact
may be  terminated  upon fifteen  (15) days  written  notice to Manager by ECSC.
Notwithstanding  the foregoing,  and to the extent  permitted by applicable law,
should ECSC attempt to effect such a  termination  of Manager's  appointment  as
attorney-in-fact  prior to the  expiration  of the  cure  periods  specified  in
SECTION 6.1 or SECTION  6.2,  ECSC  agrees to pay to Omega all  amounts  owed or
payable to Dr. Herman or to Dr. Pazandak under SECTION 2 of each of Dr. Herman's
and Dr. Pazandak's respective Employment  Agreements,  up to the amount, if any,




                                     - 64 -


<PAGE>

to which Manager is entitled under SECTION 2 of this Agreement,  until such time
as  Manager  is  reappointed  as  ECSC's  attorney-in-fact  or  this  Management
Agreement is terminated in accordance with SECTION 6 hereof. In no event shall a
default  by Manager  under this  Agreement  and/or the  cessation  of Manager as
attorney-in-fact  for ECSC, as provided in this SECTION 12, in any way change or
diminish the obligations of Manager under this Agreement.

SECTION 13.  MEDICAL OFFICE SPACE.

      Manager agrees to provide to ECSC a leasehold  interest for medical office
space (the "Medical  Office  Space")  necessary for ECSC to carry on its medical
practice at the following locations:  5421 La Sierra Drive, Dallas,  Texas; 2800
Hulen Street, Fort Worth, Texas; 4815 King Street, Greenville,  Texas; 406 South
Main, Weatherford, Texas; and such other and/or additional locations as ECSC may
designate. The leasehold interest in the Medical Office Space ("ECSC's Leasehold
Interest")  shall  be  provided  to ECSC by  separate  respective  subleases  of
Manager's leasehold interest in such Medical Office Space ("Manager's  Leasehold
Interest"),  and shall be  evidenced  by a  sublease  agreement  (the  "Sublease
Agreement") between ECSC and Manager, the terms and provisions of which shall be
substantially  the same as the terms and provisions  contained in the applicable
agreement  between  Manager  and the  party  from  whom  Manager  has  leased or
subleased  Manager's  Leasehold  Interest  (the  "Manager's  Lease");  provided,
however, anything in the Manager's Lease to the contrary  notwithstanding,  each
Sublease  Agreement shall  terminate upon the termination of this Agreement.  If
any  Manager's  Leasehold  Interest is  terminated  pursuant  to the  applicable
Manager's  Lease,  Manager,  with the prior written  consent of ECSC,  shall (i)
enter into a lease of new Medical Office Space  comparable to the Medical Office
Space in which the Manager's Leasehold Interest terminated and (ii) enter into a
Sublease Agreement with ECSC with respect to such new Medical Office Space.

SECTION 14. FEDERAL AND STATE REGULATORY COMPLIANCE; PATIENT REFERRAL.

      The parties  enter into this  Agreement  with the  intention of conducting
their  relationship in full compliance with applicable state,  local and federal
law,  including the  Medicare/Medicaid  Anti-Fraud and Abuse  Amendments and the
Texas Health & Safety Code.  Notwithstanding any unanticipated  effect of any of
the provisions herein, neither party will intentionally conduct itself under the
terms of this  Agreement  in a manner to  constitute a violation of the Medicare
and  Medicaid  Fraud  and Abuse law or Texas  Health & Safety  Code  provisions.
Nothing in this Agreement shall be construed to suggest that either party or any
related person or entity has, shall, or is obligated to compensate  either party
or any related  person or entity for referrals of patients for items or services
to the Center or to any other  provider  of goods or  services.  The parties and
related  persons and entities  shall be free to refer  patients to whomever they
see fit in the exercise of professional  judgment,  according to the convenience
or preferences of the patient, or otherwise.

SECTION 15.  ACCESS TO RECORDS.

      To the extent  required by Section  1861(v)(1)(I)  of the Social  Security
Act, each party shall,  upon proper request,  allow the United States Department
of Health and Human Services,  the Comptroller General of the United States, and
their duly authorized representatives access to this Agreement and to all books,
documents, and records necessary to verify the nature and extent of the costs of
services  provided by either party under this Agreement,  at any time during the
term of this Agreement and for an additional  period of four (4) years following
the last date  services  are  furnished  under this  Agreement.  If either party
carries out any of its duties under this Agreement  through an agreement between
it and an individual or organization related to it or through a subcontract with
an unrelated party,  that party to this Agreement shall require that a clause be
included in such  agreement  (the value of which is in excess of  $10,000.00) to
the effect that until the  expiration of four (4) years after the  furnishing of
services  pursuant  to such  agreement,  the  related  organization  shall  make
available,  upon  request by the United  States  Department  of Health and Human
Services,  the  Comptroller  General of the United States,  or any of their duly
authorized  representatives,  all agreements,  books, documents,  and records of
such related  organization that are necessary to verify the nature and extent of
the costs of services provided under that agreement.

SECTION 16.  ASSIGNMENT.

      Neither  party  shall  have  the  right  to  assign  any  of  its  rights,
obligations, or performance of services hereunder to any third party without the
prior  written  consent of the other party,  except that Manager  shall have the
right to assign its  rights  and  obligations  under  this  Agreement  to any of
Manager's Affiliates,  as well as any person or entity purchasing  substantially
all of the assets or stock of Manager  (a  "Change in Control  Event").  Manager
shall make best  efforts to notify  ECSC,  in advance,  of any Change in Control
Event,  and shall  seek  input  from ECSC  including,  but not  limited  to, the
reputation of the third party and its standing in the medical community. Nothing
in this  Section  shall be deemed to  prohibit  ECSC from  obtaining  short term
on-call services from other physicians as contemplated by SECTION 3.12.

SECTION 17.  NOTICES.

      Any  notice  hereunder  shall be deemed to have been given by one party to

SECTION 18.  AMENDMENTS.

by both parties.

       18.2  Manager  and  ECSC  acknowledge  that  the  structure,   terms  and
requirements of management agreements for medical professionals are periodically
reviewed by government  regulators  and that as new  regulations  are published,
changes  in this  Agreement  may be  required  to bring it into  conformance  or
compliance  with  these  new or  amended  regulations.  Both  parties  agree  to
implement  any  necessary  changes with the goal of, to the extent  permitted by
applicable law, not altering the basic rights or financial  advantages  accruing
to either party.

SECTION 19.  TRADEMARKS AND TRADE NAMES.

        By  this  Agreement  and  as  supported  by  the  consideration   herein
expressed,  Manager  grants  and  conveys  to ECSC  an  exclusive  license  (the

agreement between them and supersedes all previous and collateral  agreements of
understandings  relating thereto. This Agreement shall be binding upon and inure
to the benefit of each of the parties,  their respective  heirs,  successors and
assigns.  The parties acknowledge that they have access to counsel.  The parties
agree that this  Agreement  should be  construed  fairly and not against  either
party as the drafter.

      It is agreed that if any provision of this  Agreement is rendered  invalid
or  unenforceable by the decision of any court of competent  jurisdiction,  that
invalid or unenforceable  provision shall be severed from this Agreement and all
other provisions of this Agreement shall remain in full force and effect, except
that if the effect of such severance is to substantially deprive either party of
any material benefit to which it is entitled under this Agreement,  the party so
deprived may at its option  terminate  this Agreement  immediately  upon written
notice to the other party.

      IN WITNESS WHEREOF,  the parties have executed duplicate originals of this

      matters,  such  procedures may set forth required fees,  indemnifications,
      documentation and signatures (including guarantees thereof) to be obtained
      from parties requesting  reissuance of certificates.  Such procedures need
      not be  incorporated  into this  Agreement,  but a copy  thereof  shall be
      delivered to all Partners.

      Section 6.3 NO FURTHER CAPITAL CONTRIBUTIONS.  Without the approval of all
the  Partners,  no Partner  shall be  obligated  or allowed to make any  Capital

ss.1.704-1(b)(4)(iii).  The Partners'  capital accounts also shall be maintained
and    adjusted   as   permitted   by   the    provisions    of   Treas.    Reg.

such  advances  shall not result in any  increase  in the amount of the  Capital
Account of such Partner. The amounts of any such advances shall be a debt of the
Partnership to such Partner and shall be payable or collectible  only out of the
Partnership  assets in accordance  with the terms and conditions upon which such

                   ARTICLE VII - ALLOCATIONS AND DISTRIBUTIONS

      Section 7.1  ALLOCATION OF INCOME AND LOSS.  Except as otherwise  provided
for herein,  the following  provisions shall apply with regard to the allocation
of income and loss of the Partnership:

            A.  ALLOCATIONS  GENERALLY.  Except as  may  be  required by Section
      704(c) of the Code and Treas. Reg. ss.1.704-1(b)(2)(iv)(f)(4), the income,
      gains,   losses,   deductions  and  credits  (or  items  thereof)  of  the
      Partnership  shall be shared by the  Partners  in  accordance  with  their
      respective percentage Interests.  It is the intention of the Partners that
      allocations  of income,  gains,  losses,  deductions and credits (or items
      thereof)  pursuant to this Section 7.1 be in accordance with the Partners'
      Interests for tax purposes.

            B.  ALLOCATIONS WITH RESPECT TO TRANSFERRED INTERESTS.  All items of
      income, gain, loss,  deduction,  and credit allocable to any Interest that
      may have been  transferred  shall be allocated  between the transferor and
      the transferee based on the portion of the calendar year during which each
      was recognized as owning that  Interest,  without regard to the results of
      Partnership operations during any particular portion of that calendar year
      and  without  regard  to  whether  cash  distributions  were  made  to the
      transferor or the transferee during that calendar year; provided, however,

                                     - 75 -


<PAGE>

      that this allocation must be made in accordance with a method  permissible
      under Section 706 of the Code and the regulations thereunder.

      Section 7.2  DETERMINATION  OF INCOME AND LOSS.  At the end of each fiscal
year of the  Partnership,  income,  gain,  loss,  deduction and credit (or items
thereof) shall be determined by the Managing  Partner pursuant to this Agreement
for the accounting  period then ending and shall be allocated to the Partners in
accordance with Section 7.1.

      Section 7.3 CASH  DISTRIBUTIONS.  Commencing  no later than the end of the
Partnership's  first  fiscal  quarter,  the  Managing  Partner  shall,  at least
quarterly, balance the Partnership's accounts and distribute to the Partners, in
accordance  with their  respective  Interests,  the amount by which cash on hand
exceeds the amount necessary to meet the current costs, expenses and liabilities
of the Partnership (including, without limitation, a reasonably adequate reserve
for  working  capital and  contingencies).  The  Partnership  shall not make any
distribution  to  the  Partners  if,  immediately  after  giving  effect  to the
distribution,  all  liabilities of the  Partnership,  other than  liabilities to
Partners with respect to their  Interests and liabilities for which the recourse
of  creditors is limited to specified  property of the  Partnership,  exceed the
fair value of  Partnership  Property,  except that the fair value of Partnership
Property  that is subject to a  liability  for which  recourse of  creditors  is
limited shall be included in the Partnership  assets only to the extent that the
fair value of that Partnership Property exceeds that liability.

      Section  7.4  DISTRIBUTIONS  OF OTHER  PROPERTY.  From  time to time,  the
Managing  Partner also may cause property of the Partnership  other than cash to
be distributed to the Partners,  which  distribution  must be made in accordance
with their respective  Interests and may be made subject to existing liabilities
and obligations. Immediately prior to such distribution, the capital accounts of
the    Partners    shall   be   adjusted    as    provided   in   Treas.    Reg.
ss.1.704-1(b)(2)(iv)(f).

      Section 7.5  MINIMUM GAIN LIMITATIONS/ QUALIFIED INCOME OFFSET.

            A. MINIMUM GAIN DEFINED.  The term  "Minimum  Gain" means the amount
      determined by computing, with respect to each nonrecourse liability of the
      Partnership,  the amount of gain (of  whatever  character),  if any,  that
      would be realized by the Partnership if the Partnership  disposed of (in a
      taxable  transaction) the Partnership Property subject to such nonrecourse
      liability  in  full  satisfaction  thereof,  and by then  aggregating  the
      amounts so computed.


            B. NONRECOURSE DEDUCTIONS DEFINED. The term "Nonrecourse  Deduction"
      means,  for a taxable year, an amount of the net increase,  if any, in the
      amount of Minimum  Gain of the  Partnership  during that taxable year plus
      the  amount,  if any,  by which the net  increase  in Minimum  Gain of the
      Partnership  during any prior  taxable  year  exceeds the total  amount of
      items of Partnership loss, deduction and expenditures set forth in Section
      705(a)(2)(B) of the Code for such year. The  nonrecourse  deductions for a
      taxable  year  shall  consist  first  of  depreciation  or  cost  recovery
      deductions,  if any, with respect to items of Partnership Property subject
      to one or more nonrecourse liabilities of the Partnership to the extent of

                                     - 76 -


<PAGE>

      the  increase  in  the  Minimum  Gain   attributable  to  the  nonrecourse
      liabilities  to which  each such item of  property  is  subject,  with the
      remainder Nonrecourse Deductions,  if any, made up of a prorata portion of
      the  Partnership's  other items of deduction,  loss and  expenditures  set
      forth in Section 705(a)(2)(B) of the Code for that year.

            C.  DEFICIT  CAPITAL  ACCOUNT   DEFINED.   For   purposes   of  this
      Section 7.5, the term "Deficit Capital Account" means the deficit balance,
      if any, of a Partner's  Capital Account as determined  pursuant to Section
      6.4 adjusted by (i) adding  (crediting) to such Capital Account the amount
      of  such  Partner's  share  of the  Minimum  Gain,  and  (ii)  subtracting
      (debiting) from such Capital Account the amount of such Partner's share of
      the items described in Treas.  Reg. ss.ss.  1.704-1(b)(2)(ii)(d)(4),  (5),
      and (6).

            D.  PARTNER'S  SHARE OF MINIMUM  GAIN. A Partner's  share of Minimum
      Gain of the Partnership at the end of any Partnership  taxable year equals
      the aggregate  Nonrecourse  Deductions allocated to such Partner (and such
      Partner's  predecessor  in interest) up to that time,  less such Partner's
      (and such Partner's  predecessor in interest)  aggregate  share of the net
      decreases in Minimum Gain of the  Partnership up to that time. A Partner's
      share of the net  decrease  in Minimum  Gain of the  Partnership  during a
      Partnership  taxable year equals an amount that bears the same relation to
      the net  decrease in Minimum Gain of the  Partnership  during such year as
      such Partner's  share of Minimum Gain of the Partnership at the end of the
      prior taxable year of the Partnership  bears to the amount of Minimum Gain
      of the Partnership at the end of such prior taxable year.

            E. LIMITATION ON LOSS ALLOCATIONS.  Notwithstanding anything in this
      Article VII to the  contrary,  any  allocation of loss or deduction of the
      Partnership  (other than a Nonrecourse  Deduction) shall be allocated to a
      Partner  only to the  extent  that such  allocation  does not  cause  such
      Partner to have a Deficit Capital Account.

            F.  MINIMUM  GAIN  CHARGEBACK.   Notwithstanding   anything  in  the
      foregoing sections of this Article VII to the contrary,  in the event that
      there is a net  decrease  in Minimum  Gain of the  Partnership  during the
      Partnership's  taxable year, all Partners with a Deficit  Capital  Account
      will be allocated,  before any other  allocations of Partnership items for
      such taxable year under this Agreement,  items of income and gain for such
      year  (and,  if  necessary,  subsequent  years)  in an  amount  needed  to
      eliminate such deficit as quickly as possible. The Minimum Gain chargeback
      allocated in any taxable year shall consist first of gains recognized from
      the  disposition of items of Partnership  Property  subject to one or more
      nonrecourse  liabilities of the  Partnership to the extent of the decrease
      in Minimum Gain  attributable to the disposition of such items of property
      with the remainder of such Minimum Gain  chargeback,  if any, made up of a
      prorata  portion of the  Partnership's  other items of income and gain for
      that year.

            G.  QUALIFIED  INCOME  OFFSET.   Notwithstanding   anything  in  the
      foregoing sections of this Article VII to the contrary,  in the event that
      any  Partner  unexpectedly  receives  any  adjustments,   allocations,  or
      distributions described in Treas. Reg. ss.ss.1.704-1(b)(2)(ii)(d)(4),  (5)
      or (6), which causes a deficit  balance in such Partner's  Capital Account
 
                                     - 77 -


<PAGE>

      (or causes an increase in an existing  deficit  balance in such  Partner's
      Capital  Account),  items of income  and gain shall be  allocated  to such
      Partner  in an amount and  manner  sufficient  to  eliminate  the  deficit
      balance  in  such  Partner's  Capital  Account  as  quickly  as  possible;
      provided,  however,  that  allocations  of  income or gain  shall  only be
      required pursuant to this Subsection G of Section 7.5 if and to the extent
      that the  foregoing  adjustments,  allocations  or  distributions  cause a
      Deficit  Capital  Account  of the  Partners  receiving  such  adjustments,
      allocations, or distributions determined at the end of the taxable year of
      the Partnership to which such allocations relate.

      Section 7.6  COMPLIANCE  WITH SECTION 704 OF THE CODE.  The  provisions of
this Agreement  relating to maintenance of Capital  Accounts and the computation
and  allocation  of net income,  gains,  and losses are  intended to comply with
Section  704 of the  Code and the  Regulations  thereunder  (including,  without
limitation,  the provisions  regarding  substantial  economic effect,  qualified
income offset,  allocations of nonrecourse deductions,  minimum gain chargeback,
and  other  considerations  under  Section  704 of the Code and the  Regulations
thereunder),  and shall be interpreted  and applied in a manner  consistent with
Section  704 of the Code and such  Regulations  in order to  achieve  the agreed
allocation of cash among the Partners.  In the event the Partners determine that
it is prudent or necessary  to modify the manner in which the Capital  Accounts,
or any debits or credits  thereto,  are computed or allocated in order to comply
with Section 704 of the Code and/or the  Regulations  thereunder  and/or to make
any optional  elections  thereunder,  the Partnership may make such modification
and/or  election,  including an amendment to this Agreement if the Partners deem
it necessary. The Partners shall also make any appropriate modifications to this
Agreement in the event unanticipated events might otherwise cause this Agreement
not to comply with  Section 704 of the Code and/or the  Regulations  thereunder.
Further,  notwithstanding  anything to the contrary contained in this Agreement,
if the Regulations  thereunder  require an allocation of net income,  gains, and
losses in a manner different from that set forth in Article VII (other than this
Section 7.6) of this Agreement, such allocations shall be taken into account for
the purpose of equitably adjusting subsequent  allocations of net income, gains,
and losses so that the net cumulative allocations,  in the aggregate,  allocated
to each  Partner  pursuant  to Article  VII of this  Agreement,  including  this
Section  7.6 shall,  as  quickly as  possible  and to the extent  possible,  and
without violating the constraints  contained in this Section 7.6, be the same as
if no such  allocations  had been made under this Section 7.6 so that the agreed
upon allocation of cash among the Partners will be respected.

      Section 7.7 SAVINGS  CLAUSE.  The tax allocation  provisions  contained in
Article VII of this  Agreement  are intended to produce  final  Capital  Account
balances that are at levels ("Target Final Balances")  which permit  liquidating
distributions  that are made in  accordance  with  such  final  Capital  Account
balances to be equal to distributions  that would occur on final  liquidation of
the Partnership.  To the extent that the tax allocation  provisions contained in
Article VII of this Agreement would not produce the Target Final  Balances,  the
provisions  of this  Agreement  shall be amended to produce  such  Target  Final
Balances. Notwithstanding the other provisions of this Agreement, allocations of
net income,  gains,  and losses  shall be made  prospectively  as  necessary  to
produce  such  Target  Final  Balances  (and,  to the  extent  such  prospective
allocations  would  not  reach  such  result,  the  prior  tax  returns  of  the
Partnership  shall be amended to reallocate  Partnership net income,  gains, and
losses to produce such Target Final Balances).

      Section 7.8 DEPRECIATION  RECAPTURE.  To the extent not inconsistent  with
the  foregoing  provisions  of this  Article  VII,  any gain of the  Partnership
attributable to depreciation  recapture shall be allocated among the Partners in
proportion with the depreciation deductions previously allowable to the Partners
with respect to the assets generating such recapture.

eligible  Person's  representative,  at any  reasonable  time,  for  any  proper

significant  matters  that may come to its  attention  in its  capacity  as "tax
matters  partner" by giving notice  thereof on or before the fifth  Business Day
after becoming aware thereof and, within that time,  shall forward to each other
Partner copies of all significant written  communications it may receive in that
capacity.  The Managing Partner may not take any action contemplated by Sections
6222  through  6232 of the Code  without the consent of the  Partners,  but this
sentence does not authorize the Managing  Partner to take any action left to the
determination  of an individual  Partner under Sections 6222 through 6232 of the
Code.

      Section 11.1 AUTHORITY.  Except as otherwise specifically provided in this
Agreement,  no Partner has the authority or power to act for or on behalf of the
Partnership, to do any act that would be binding on the Partnership, or to incur
any expenditures on behalf of the Partnership.

      Section 11.2 TRANSFERS OF INTERESTS.  A Partner may make a Transfer of his
Interest,  in  whole  or in  part,  only  upon  compliance  with  the  following
procedure:

            A.  DOCUMENTATION.  The Partner or the  transferee  must  file  with
      the  Partnership  a written and dated  instrument  of  such  Transfer,  in





                                     - 84 -


<PAGE>

      form  and  substance  reasonably  satisfactory   to  the  other  Partners,
      executed by both the transferor and the transferee, which instrument shall
      (i)  contain  the  acceptance  by the  transferee  of all of the terms and
      provisions of this Agreement,  to the extent  applicable to an assignee of
      an  Interest,  (ii) contain  such  representations  as may be necessary or
      advisable to assure that such Transfer  need not be  registered  under any
      applicable   federal  or  state   securities   laws,  (iii)  instruct  the
      Partnership as to the Interest transferred and to whom and at what address
      Partnership  distributions  and  Notifications in respect of such Interest
      should henceforth be sent, and (iv) contain any information required under
      the Code that is requested by the other Partners.

            B.  OPINION  OF  COUNSEL.  Unless  expressly  waived  by  the  other
      Partners,  the transferor  Partner or the transferee  shall deliver to the
      Partnership  an opinion of counsel  acceptable to the other  Partners that
      (i) such  Transfer is exempt  from the  registration  requirements  of the
      Securities Act of 1933, as amended,  applicable state securities laws, and
      any rules or regulations  promulgated  thereunder,  and will not otherwise
      cause the  Partnership  to be in violation  of such laws and  regulations,
      (ii) the Transfer will not result in the  termination  of the  Partnership
      within the meaning of section  708(b) of the Code,  and (iii) the Transfer
      will not adversely  affect the status of the  Partnership as a partnership
      under the Code.

            C. APPROVAL OF PARTNERS.  The transferor  Partner and the transferee
      shall have received a written  acknowledgment from the other Partners that
      the  Transfer  has  been  approved  by all  Partners  of the  Partnership;
      provided,  however,  that the Interest of any individual  Partner shall be
      transferrable  without the  approval of the other  Partners if both of the
      following  factors  apply:  (i) such  Transfer  occurs  by  reason  of the
      dissolution  and  liquidation  of the  Partner  and each  transferee  is a
      shareholder  or  successor  in  interest  to the  Partner;  and (ii)  each
      transferee otherwise complies with the provisions of paragraphs A and B of
      this Section 11.2.

      Section  11.3 EFFECT OF TRANSFER  OF  INTEREST.  A Transfer of an Interest
pursuant to Section 11.2 above does not entitle the transferee to become,  or to
exercise rights or powers of, a Partner. A Transfer only entitles the transferee
to receive cash distributions and allocations of Partnership  profits and losses
to the extent of the Interest transferred. Until the transferee is admitted as a
Partner pursuant to Section 11.4 below, the transferor Partner shall continue to
be a Partner and to be  entitled  to exercise  any rights or powers of a Partner
with respect to the Interest transferred.

      Section  11.4  ADMISSION  OF  TRANSFEREE  AS PARTNER.  A  transferee  of a
Partner's  Interest  desiring  to  be  admitted  as a  Partner  must  execute  a
counterpart of, or an agreement adopting, this Agreement.  The admission of such
transferee is subject to the unanimous approval of the Partners.  Upon admission
of the transferee as a Partner,  the transferee shall have, to the extent of the
Interest  transferred,  the  rights  and  powers,  and shall be  subject  to the
restrictions and liabilities of, a Partner under this Agreement and the Act. The
transferee shall also be liable, to the extent of the Interest transferred,  for
the unfulfilled  obligations,  if any, of the transferor Partner to make Capital
Contributions,  but  shall  not be  obligated  for  liabilities  unknown  to the
transferee at the time the  transferee  was admitted as a Partner and that could
not be  ascertained  from this  Agreement.  Whether or not the  transferee of an

required  in  connection  with the use of a  written  consent  pursuant  to this

an  execution in writing for  purposes of this  Section.  Proxies for use at any
meeting of  Partners or in  connection  with the taking of any action by written
consent  shall be filed with the General  Partner,  before or at the time of the
meeting or  execution  of the written  consent,  as the case may be. All proxies
shall be  received  and taken  charge of and all ballots  shall be received  and
canvassed by the Managing  Partner who shall decide all questions  touching upon
the qualification of voters, the validity of the proxies,  and the acceptance or
rejection of votes,  unless an inspector or inspectors shall have been appointed
by the chairman of the  meeting,  in which event such  inspector  or  inspectors
shall  decide all such  questions.  No proxy  shall be valid  after  eleven (11)
months from the date of its execution unless otherwise  provided in the proxy. A
proxy shall be  revocable  unless the proxy form  conspicuously  states that the
proxy is irrevocable  and the proxy is coupled with an interest.  Should a proxy
designate two or more Persons to act as proxies,  unless such  instrument  shall
provide to the  contrary,  a majority of such Persons  present at any meeting at
which their powers  thereunder  are to be exercised  shall have and may exercise
all the powers of voting or giving consents thereby conferred, or if only one be
present,  then such powers may be  exercised  by that one; or, if an even number
attend and a majority  do not agree on any  particular  issue,  the  Partnership
shall not be required to recognize such proxy with respect to such issue if such
proxy does not specify how the Interests  that are the subject of such proxy are
to be voted with respect to such issue.

set  forth in this  Agreement,  each  Partner  is  entitled  to all  information

            payment or establishment of reserves;

an  asset of the  Partnership  and  such  Partners  shall  not be  obligated  to

             ARTICLE XIV - LIABILITY, INDEMNIFICATION AND INSURANCE

      Section  14.1  LIABILITY  OF  PARTNERS.  No Partner  nor any  shareholder,
director,  officer, agent, affiliate or employee of any Partner shall be liable,
responsible  or  accountable  in damages or otherwise to the  Partnership or any
other  Partner  for  any  action  taken  or  failure  to  act on  behalf  of the
Partnership within the scope of the authority  conferred on such Partner by this
Agreement  or by law unless such act or omission  constituted  willful or wanton
misconduct  or  was  performed  or  omitted  fraudulently  or in  bad  faith  or
constituted gross negligence. No Partner nor any shareholder, director, officer,
agent,  affiliate or employee of any Partner shall be personally  liable for the
return or repayment of all or any portion of the capital or profits of any other
Partner (or transferee thereof),  it being expressly agreed that any such return
of capital or profits made pursuant to this Agreement  shall be made solely from
the assets of the Partnership.  Nothing herein shall be interpreted to (i) limit
the  liability  of any Partner with  respect to debts and  obligations  to third
parties under Section 3.04 of the Act, (ii) limit the  obligation of any Partner
to transfer to the Partnership the full amount of such Partner's Initial Capital
Contribution and subsequent  capital  contributions,  if any, or (iii) limit the
liability of any Partner with respect to the  fiduciary  duty of such Partner to
the Partnership or to the other Partners.

      Section  14.2   REIMBURSEMENT  AND   INDEMNIFICATION   OF  PARTNERS.   The
Partnership  shall  promptly  reimburse and indemnify each Partner in respect of
reasonable  payments made and personal  liabilities  reasonably incurred by such
Partner  for  services  performed  for  the  benefit  of or  on  behalf  of  the
Partnership business,  or for the preservation of the Partnership's  business or
property.  Without limiting the generality of the foregoing,  in any threatened,
pending,  or contemplated  action,  suit or proceeding to which a Partner and/or
any officer, director, shareholder, agent, affiliate or employee of such Partner
(collectively, the "Indemnified Parties"), was or is a party or is threatened to
be made a party by reason or because  of the fact that such  Partner is or was a
Partner  in the  Partnership  (including  any  action  by or in the right of the
Partnership),  the Partnership  shall indemnify the Indemnified  Parties against
expenses,  including  attorneys' fees,  judgments and amounts paid in settlement
incurred by the  Indemnified  Parties in  connection  with such action,  suit or
proceeding if the Indemnified Parties acted in accordance with the standards set
forth in  Section  4.04 of the  Act.  The  termination  of any  action,  suit or
proceeding  by  judgment,  order or  settlement  shall not, of itself,  create a
presumption  that the  Indemnified  Parties did not act in accordance  with such
standards.  Nothing  herein  shall be  interpreted  to  indemnify  or limit  the
liability  of  any  Partner  with  respect  to  debts  or   obligations  of  the
Partnership.   Nothing   herein  shall  be  considered  to  guarantee  that  the
Partnership  or any of the  Partners  shall gain or derive any profit or benefit
from the operations of the Partnership's  business or that such operations shall
result in any particular outcome.

in this  Article XIV shall in no event cause the  Partners to incur any personal
liability beyond their total Capital  Contributions,  nor shall it result in any
liability of the Partners to any third party.

      Section 14.4  INSURANCE.  To the extent not prohibited by applicable  law,
the Partnership may purchase and maintain  insurance or another  arrangements on
behalf of any Person who is or was an  Indemnified  Party  against any liability
asserted against him or incurred by him in such a capacity or arising out of his
status as an Indemnified Party.

in the  Partnership  to Omega  upon  written  notice  to Omega  (the  "SEC  Sale
Notice"). Upon the expiration of one hundred eighty (180) days following the SEC
Sale Notice (the "Sale Date"), Omega shall purchase from SEC, and SEC shall sell
to Omega, SEC's Interest at the Buyout Amount.

      Section 15.4 MANDATORY SALE AND PURCHASE FROM EVENT  INVOLVING DR. HERMAN.
In the event that at any time beginning September 1, 2001, Dr. Herman decides to
partially  retire from ECSC II by choosing to reduce the number of Required Work
Days, in the manner provided in Section 13 of the Herman  Employment  Agreement,
to a lesser  number of days (the "Herman Work Days"),  SEC is obligated to sell,
and Omega is obligated  to buy, a portion of the SEC  Interest  that is equal to
the "Herman  Partial  Retirement  Portion"  (hereinafter  defined).  The "Herman
Partial Retirement  Portion" means a portion of the Partnership that is owned by
SEC that is the  result of (A) an  amount  equal to fifty  percent  (50%) of the
product of (1) the  result of (a) 1.000  minus (2) a  fraction  (expressed  as a
decimal),  the  denominator of which is the Required Work Days and the numerator
of which is the Herman Work Days  multiplied by (b)  twenty-five  one hundredths
(.25),  minus (B) an amount  (if any) equal to the SEC  Interest  that Omega was
previously  required  to buy from SEC  pursuant  to the first  sentence  of this
Section 15.4. For example,  and for purposes of illustration only, if the Herman
Work Days equals 106 days and Omega was not previously required to buy a portion
of the SEC Interest  pursuant to the first  sentence of this Section  15.4,  SEC
would be required to sell,  and Omega would be required to buy, a 6.25% Interest
in the  Partnership  ([{[1.000  - .500] x .25} x .50] - 0.00 =  .0625),  and the
Herman  Allocable  Portion As Adjusted  would then equal a 6.25% interest in the
Partnership (.125 - .0625 = .0625).  Further,  upon the occurrence of any one of
the following  events:  (i) the death of Dr. Herman;  (ii) the Disability of Dr.
Herman;  or  (iii)  the full  retirement  of Dr.  Herman  from  ECSC II,  SEC is
obligated to sell, and Omega is obligated to buy, that portion of SEC's Interest
that is equal to the  smaller  of (a) the  Herman  Allocable  Portion or (b) the
Herman  Allocable  Portion As Adjusted.  Upon the  expiration of sixty (60) days
following the Trigger Date, Omega shall purchase from SEC, and SEC shall sell to
Omega,  at the  Buyout  Amount,  the  portion  of the SEC  Interest  that SEC is
required to sell,  and that Omega is required to buy,  under the  provisions  of
this Section 15.4.

      Section  15.5  MANDATORY  SALE  AND  PURCHASE  FROM  EVENT  INVOLVING  DR.
PAZANDAK.  In the event that any time beginning  September 1, 2001, Dr. Pazandak
decides to  partially  retire  from ECSC II by  choosing to reduce the number of
Required  Work Days,  in the  manner  provided  in  Section  13 of the  Pazandak
Employment Agreement, to a lesser number of days (the "Pazandak Work Days"), SEC
is  obligated  to sell,  and Omega is  obligated  to buy,  a portion  of the SEC
Interest that is equal to the "Pazandak Partial Retirement Portion" (hereinafter
defined).  The  "Pazandak  Partial  Retirement  Portion"  means a portion of the
Partnership  that is owned by SEC that is the  result of (A) an amount  equal to
fifty  percent  (50%) of the  product of (1) the result of (a) 1.000 minus (2) a
fraction (expressed as a decimal), the denominator of which is the Required Work
Days and the  numerator of which is the  Pazandak  Work Days  multiplied  by (b)
twenty-five one hundredths (.25),  minus (B) an amount (if any) equal to the SEC
Interest  that Omega was  previously  required  to buy from SEC  pursuant to the
first  sentence  of  this  Section  15.5.  For  example,  and  for  purposes  of
illustration  only,  if the  Pazandak  Work  Days  equals  53 days and Omega was
previously  required  to buy a  3.125%  interest  in the  Partnership  from  SEC
pursuant to the first  sentence of this Section  15.5,  SEC would be required to
sell,  and Omega would be required to buy, a 6.25%  Interest in the  Partnership

                                     - 94 -

([{[1.000 - .250] x .25} x .50] - .03125 = .0625),  and the  Pazandak  Allocable
Portion As Adjusted would then equal a 3.125% interest in the Partnership ([.125
- - .03125] - .0625 =  .03125).  Further,  upon the  occurrence  of any one of the
following  events:  (i) the death of Dr.  Pazandak;  (ii) the  Disability of Dr.
Pazandak;  or (iii) the full  retirement  of Dr.  Pazandak  from ECSC II, SEC is
obligated to sell, and Omega is obligated to buy, that portion of SEC's Interest
that is equal to the smaller of (a) the  Pazandak  Allocable  Portion or (b) the
Pazandak  Allocable Portion As Adjusted.  Upon the expiration of sixty (60) days
following the Trigger Date, Omega shall purchase from SEC, and SEC shall sell to
Omega,  at the  Buyout  Amount,  the  portion  of the SEC  Interest  that SEC is
required to sell,  and that Omega is required to buy,  under the  provisions  of
this Section 15.5.

      Section 15.6 PAYMENT OF THE BUYOUT AMOUNT. The Buyout Amount shall be paid
by Omega to SEC by  delivery  to SEC of (i) an amount of cash  equal to at least
fifty  percent  (50%) of the  Buyout  Amount,  and (ii) an  amount  equal to the
difference  between the Buyout Amount minus the amount of cash paid to SEC under
(i) of this Section 15.6 which shall,  at the option of Omega,  be paid in cash,
in  unregistered  common stock (the  "Stock") of Omega Health  Systems,  Inc., a
Delaware  corporation ("OHS"), or in a combination of both. For purposes of this
Section  15.6,  the Stock shall be valued at the average of the closing price of
the publicly  traded common stock of OHS for the twenty (20) trading days ending
four (4) trading days prior to the date that the  certificates  representing the
Stock are required to be delivered to SEC.
