Community Hospital,  Central General Hospital,  Huntington Hospital,  St. John's
Hospital,  Mather, Central Suffolk/Eastern Long  Island/Southampton,  Brookhaven

criteria,  propose to MDLI the network of hospitals which will contract with the
Hospital  IPA  as  participating  providers,   subject  to  MDLI's  approval  or
disapproval  of such  network;  provided  that  MDLI  shall  not  add or  delete
individual hospitals as providers contracting with the Hospital IPA, without the
concurrence  of CHNLI and the Hospital IPA. If the Hospital IPA is not approved,
CHNLI shall,  in its  discretion and subject to the above  criteria,  propose to
MDLI the network of hospitals  which will  contract  with MDLI as  participating
providers,  subject to MDLI's approval or disapproval of such network;  provided
that MDLI shall not add or delete individual hospitals as providers  contracting
with it without the concurrence of CHNLI. If the Hospital IPA is approved,  MDLI
shall negotiate the rates to be paid to participating hospitals, subject to such
guidelines as may be contained in the risk-sharing  arrangement between MDLI and
the Hospital IPA, and compliance with all applicable laws.

            (c) The parties  hereto  acknowledge  that Good  Samaritan  Hospital
Medical  Center,  which is one of the CHNLI  Hospitals,  is a party to a Consent
Decree/Final  Judgment  with the U.S.  Department  of Justice in U.S. v. Classic
Care Network Inc.,  and that  pursuant to that Final  Judgment,  Good  Samaritan
Hospital Medical Center is required to give notice of certain  activities to the
Justice  Department.  The parties  acknowledge  that the Justice  Department may
review the MDLI hospital  network and  relationships  with respect to compliance
with the antitrust laws and may make  recommendations  with respect thereto, and
the parties agree to comply with any such  recommendations.  The parties  hereto
further  acknowledge  that the Department may, from time to time,  review MDLI's
hospital network, and make recommendations thereto, and the parties hereto agree
to comply with any Department requirements.

      8.5 Risk Sharing Arrangement.

            (a) MDLI  shall,  pursuant  to a budget  duly  adopted by its Board,
allocate  the  premium  dollars   received  from  Members  between  amounts  for
administrative  expenses  and reserves on the one hand and amounts to be used to
pay for all types of medical  expenses  on the other hand.  Of the total  amount
MDLI allocates to pay for medical  expenses each year, MDLI shall allocate funds
("Percentage of Medical Expense") between a Hospital Pool, a Physician Pool, and
a Carve-Out Pool in accordance with Schedule 8.5 attached  hereto.  MDLI further
agrees  to  allocate  the  Hospital  Pool  between  two  sub-pools,  one for all
in-patient  stays  attributable to psychiatric,  alcohol and/or  substance abuse
stays  ("Behavioral  Health  Hospital  Pool") and one for all other  in-patient,
emergency room,  ambulatory  surgery,  and home health


                                       9
<PAGE>

stays  ("Med-Surg  Hospital  Pool") in accordance with Schedule 8.5. MDLI agrees
that the Percentage of Medical Expense and the Utilization  Targets set forth in
Schedule 8.5 with respect to the Hospital Pool and each of its  sub-pools  shall
be the  minimum  amount it shall  allocate to each of these  pools,  and that it
shall fund these pools, at a minimum, according to these amounts.

            (b) The Hospital  IPA, if approved,  shall be entitled to 1/3 of any
surplus  in each  of the  Hospital  Sub-pools  (i.e.,  in  each of the  Med-Surg
Hospital Pool and the Behavioral  Health  Hospital  Pool).  The Hospital IPA, if
approved,  shall be responsible  for 1/3 of any deficit in excess of 110% of the
total  deficit in the combined  Hospital  Pool (i.e.  combining the two Hospital
Sub-pools  and  calculating  any  deficit  in the  combined  Sub-pools).  If the
Hospital  IPA is not  approved,  each  CHNLI  Hospital  may  elect,  in its sole
discretion,  to enter into a  risk-sharing  arrangement  with MDLI in which such
CHNLI  Hospital would bear 1/3 of the risk of any surplus and 1/3 of the risk of
any deficit in excess of 110% of the total deficit in the Combined Hospital Pool
in its LDU,  and,  for any LDU in which a CHNLI  Hospital has not agreed to bear
risk,  MDLI shall  bear the same  proportion  of risk of any  surplus or deficit
which the Hospital IPA, if approved, would have borne.

            (c) The  parties  agree  that  LIPHC or a  DOH-approved  independent
practice  association  formed by LIPHC or the physicians who sign  participating
provider agreements with a DOH-approved  independent practice association formed
by LIPHC shall bear the  remainder  of the risk of any deficit or surplus in the
Hospital  Pool in  accordance  with the  terms  of  Schedule  8.5 as more  fully
explained below:

                  (i) With respect to the  Med-Surg  Hospital  Pool,  MDLI shall
divide the Service  Area into a series of local  delivery  units (each such unit
within the Service Area, an "LDU").  Each LDU will be its own economic unit, and
the method for funding the Med-Surg  Hospital  Pool in each LDU shall be uniform
and shall be in accordance with Schedule 8.5. MDLI participating physicians and'
other   participating   practitioners   who  participate  with  Island  Practice
Association,  I.P.A.,  Inc.  ("Island  IPA")  will  each  select  an LDU  (which
selection may be based upon  traditional  referral  patterns,  as well as office
location). The Island IPA participating practitioners who have selected the same
LDU and have entered into  participating  provider  agreement  agreeing to share
risks  within their LDU shall be known as "LDU  Physicians,"  and shall agree to
share risk within  their LDU as set forth in Schedule  8.5.  MDLI and LIPHC each
agree that  either MDLI or Island IPA shall  enter into  participating  provider
contracts with each LDU Physician which will obligate each such physician to the
risk-sharing  arrangement  set forth in this Section 8.5 and which shall entitle
MDLI or Island IPA to deduct from any funds owed or to be paid to such physician
for rendering professional services the amount of any deficit to be allocated to
such physician pursuant to this section. The LDU Physicians and Island IPA shall
be responsible  for all deficits  experienced by the LDU  Physician's LDU in the
Med-Surg  Hospital Pool,  except as set forth in Section  8.5(b).  Downside risk
will be minimized by MDLI being  responsible  for in-patient  costs in excess of
$50,000 for each patient whose annual in-patient hospital costs are in excess of
$50,000  per  year.  The  cost of high  risk  cases  (i.e.,  organ  transplants,
extensive burns,  HIV) shall be borne by all  Nassau/Suffolk  County LDUs either
through  reinsurance  or other  stop-loss  mechanisms  funded  by MDLI.  The LDU
Physicians  within each LDU shall be entitled to 2/3 of any surplus generated in
the Med-Surg Hospital Pool within their LDU.


                                       10
<PAGE>

                  (ii) With  respect to the  Behavioral  Health  Hospital  Pool,
certain MDLI participating physicians and other participating  practitioners who
participate with the Island Behavioral Health Association I.P.A.  ("IBHA") shall
be responsible  for all deficits  experienced by the Behavioral  Health Hospital
Pool,  except  as set  forth  above in  Section  8.5(b).  Downside  risk will be
minimized by MDLI being  responsible for in-patient  behavioral  health hospital
costs in excess of $50,000 for each patient whose annual  in-patient  behavioral
health  hospital  costs are in excess of $50,000  per year.  MDLI and LIPHC each
agree that either MDLI or IBHA shall enter into participating provider contracts
with each physician which will obligate each such physician to the  risk-sharing
arrangement set forth in this Section 8.5 and which shall entitle MDLI, or IBHA,
to deduct  from any funds  owed or to be paid to such  physician  for  rendering
professional  services  the  amount  of any  deficit  to be  allocated  to  such
physician pursuant to this section. IBHA shall be entitled to 2/3 of any surplus
generated in the Behavioral Health Hospital Pool.

            (d) There  shall be no  allocation  of  surplus  or  deficit  to the
Hospital IPA, if approved,  or to a CHNLI Hospital or to MDLI from the Physician
Pool or the Carve-Out  Pool,  including no allocation of surplus or deficit from
the provision of dental or chiropractic services.

            (e) MDLI agrees to be responsible for costs in excess of $10,000 per
year for each patient  whose annual costs for services  covered by the Physician
Pool exceed $10,000 per year.

      8.6 Management Contracts.

            (a) The  parties  hereto  agree  that in the  event  any  management
services are needed by the IPA if approved,  such IPA shall contract Management,
Inc.,  a Delaware  corporation  affiliated  with LIPHC and CHNLI  ("NextStage");
provided  that such  services are provided by NextStage on terms and  conditions
that are  competitive  with other  management  services  providers.  The parties
hereto agree and acknowledge that certain terms and conditions of any management
agreement,  including,  without  limitation,  management  fees,  are governed by
regulations  promulgated  by the  Department,  and  that  the  final  terms  and
conditions of any management  agreement  shall be subject to review and comments
by the Department.

            (b) In  addition  to any  management  agreement  between  the IPA if
approved,  and  NextStage,  MDLI shall  enter into an  agreement  with LIPHC and
CHNLI.  Pursuant to the terms of this  agreement,  LIPHC and CHNLI shall perform
various specified duties and provide consulting services to MDLI in exchange for
a fee equal to one percent  (1%) of MDLI  premium  revenues,  once a  break-even
point has been  achieved  by MDLI.  The fee  payable by MSLI shall be  allocated
between LIPHC and CHNLI at a ratio of  two-thirds-to-one-third  (2/3:  1/3). For
purposes of the foregoing, "break-even" with respect to MDLI shall mean the date
on which MDLI has 50,000 HMO enrollees.

      8.7 Exclusivity.

            (a)  CHNLI  Hospitals  shall  be  engaged  by MDLI as the  exclusive
in-patient  provider of available  services within each CHNLI  Hospital's  local
service  area.  The parties  hereto agree and  acknowledge  that the list of the
CHNLI  Hospitals  attached  hereto as Schedule


                                       11
<PAGE>

8.7(a)  identifies all services  available at the respective CHNLI Hospitals for
which such hospital shall be the exclusive provider of such in-patient  services
for MDLI. Schedule 8.7(a)also defines each CHNLI Hospital's local service area.

            (b) In  addition  to being  the  exclusive  in-patient  provider  of
available  services,  Mercy Medical  Center and St.  Charles  Hospital  shall be
engaged by MDLI as the exclusive providers of in-patient rehabilitation services
for MDLI  members  residing  within  Nassau  and  Suffolk  Counties,  New  York,
respectively;  provided  that  the  total  reimbursement  arrangement  for  such
in-patient  rehabilitation  services  compares  favorably  with  Mercy's  or St.
Charles' total  reimbursement  arrangement for comparable  services with any HMO
certified pursuant to New York State law. This exclusive  provision is dependent
upon an  adequate  number  of  appropriately  qualified  Mercy  and St.  Charles
physicians  agreeing to be MDLI  participating  providers  who can provide  such
services.

            (c) St. Francis Hospital shall be engaged as the exclusive  contract
provider of tertiary cardiac services for Nassau and Suffolk Counties,  New York
(except where  performed by other CHNLI  Hospitals),  including  PTCA's and open
heart  surgery,  for MDLI members,  provided that St.  Francis  provides  timely
access to MDLI members and the total reimbursement arrangement for such services
compares  favorably  with  St.  Francis'  total  reimbursement  arrangement  for
comparable  services with any HMO certified pursuant to New York State law. With
respect to  electrophysiology  services  (EPS),  this exclusive  provision shall
apply only when a  participating  hospital does not perform said  service.  This
exclusive  provision  is  dependent  upon an  adequate  number of  appropriately
qualified St. Francis'  physicians  agreeing to be MDLI participating  providers
who can provide such services.

            (d) The  parties  hereto  agree  that  entities  owned,  managed  or
otherwise  affiliated  with either  CHNLI (such as  Catholic  Charities  and the
Nursing Sisters Home visiting Services) or LIPHC that provide ancillary services
shall be engaged by MDLI as the exclusive  providers of the respective  services
provided by such entities in the Service  Area,  provided that such services are
provided on as competitive terms and conditions, including price and quality, to
MDLI and its enrollees/subscribers as they could receive from other providers of
such care.

            (e) With the  exception  of St.  Francis,  CHNLI  shall use its best
efforts to cause each CHNLI Hospital to extend privileges on a full or qualified
basis,  to all MDLI  providers who seek to have  privileges at such hospital and
otherwise qualify and meet the standards  maintained by such CHNLI Hospital.  In
accordance with applicable  by-laws and medical staff  regulations of each CHNLI
Hospital,  CHNLI  Hospitals  shall use their  best  efforts  to grant  admitting
privileges  to MDLI  providers  that,  with  respect to the  coverage  and other
obligations  of the MDLI  provider,  allow for some  reduction or elimination of
such  obligations  where  the  MDLI  provider   maintains  his  or  her  primary
affiliation with another  hospital and where the number of patients  admitted by
such provider to the CHNLI hospital is not large enough to warrant requiring the
provider to satisfy all of the otherwise applicable obligations.

            (f) The parties hereto agree that Schedule  8.7(f)  attached  hereto
identifies: (1) all Article 28 and Article 36 services available from respective
CHNLI Hospitals for which such hospitals shall be the exclusive provider of such
services in the  respective  local  services area for the CHNLI Hospital and (2)
all other  out-patient  services for which CHNLI  Hospitals  shall be


                                       12
<PAGE>

either the exclusive  provider of a preferred provider in the respective service
area of such hospital, as noted in the attached Schedule 8.7(f).

            (g) For the purposes of the foregoing,  "exclusive  provider"  shall
mean that,  for the  applicable  geographic  area or treatment  specified,  MDLI
participating  physicians  shall be  required  to refer  and/or  admit  patients
requiring  hospital-based  care to the appropriate CHNLI Hospital,  except where
the referral or the admission of the patient to another  participating  hospital
is justified by documented  market-related factors (including factors related to
the market for purchasing HMO services,  such as employer  requirements),  sound
medical judgment, or justifiable concerns for  patient-subscriber  satisfaction.
It is further agreed by the parties hereto that referral  patterns and practices
subject to these provisions shall be the subject of ongoing review by MDLI. MDLI
will  implement  a  precertification  program to  monitor  this  provision.  For
purposes  of the  foregoing,  "preferred  provider"  shall  mean that MDLI shall
contract  with each CHNLI  Hospital  to  provide  the  specified  service in its
service area,  but that MDLI may also  contract with other  providers to provide
such service.

      8.8 Future Expansion.  The parties hereto agree and acknowledge that it is
the intent of MDLI to expand its Service Area to include  other  counties in New
York  State  under the name of MDNY  Healthcare,  Inc.  (the  application  for a
certificate  of  authority  to  operate  an HMO  currently  pending  before  the
Department relates to Nassau and Suffolk Counties, only). In furtherance of this
intended  expansion,  the  parties  recognize  that there may be some  degree of
dilution  of  their  initial  equity  positions  and  the  corporate  governance
associated with such equity positions,  and agree to negotiate in good faith all
future  expansion plans and  strategies,  and to effect those  transactions,  if
necessary,  that may result in dilution  and/or other  changes in the  corporate
governance  of MDLI. It is the further  intent of the parties  hereto that LIPHC
shall be  responsible  for  establishing  the physician  and ancillary  provider
networks,  and CHNLI or an entity formed by,  affiliated  with, or designated by
CHNLI  shall  be  responsible,   if  CHNLI  or  such  entity  elects,   for  the
establishment of the hospital network, including the sale of ownership interests
in such network, if appropriate, in any expanded MDLI Service Area. In the event
CHNLI or an entity formed by,  affiliated  with, or designated by CHNLI can not,
or elects not to,  establish a hospital  network in such  expanded  Service Area
within the time  allotted  for such  establishment  by MDLI,  MDLI shall  assume
responsibility  for establishing the hospital network.  CHNLI shall use its best
efforts to assist  LIPHC and MDLI if and when a  decision  is made to expand the
Service Area of MDLI beyond Nassau and Suffolk Counties, New York.

      8.9 Other Terms and Conditions.

            (a) LIPHC shall grant to CHNLI the  opportunity to  participate  (on
terms and conditions to be agreed upon, however, in no event less favorable than
terms and  conditions  available  from an  unaffiliated  third party) in any new
venture  proposed to be entered into by LIPHC to the extent LIPHC seeks or plans
to seek equity participants who are outside investors,  and CHNLI shall grant to
LIPHC the opportunity to participate (on terms and conditions to be agreed upon,
however, in no event less favorable than terms and conditions  available from an
unaffiliated third party) in any new, non-Article 28-related venture proposed to
be  established  by  CHNLI to the  extent  CHNLI  seeks or plans to seek  equity
participants who are outside investors.


                                       13
<PAGE>

            (b) LIPHC hereby  agrees not to acquire,  establish or invest in, in
any Service Area in which CHNLI  Hospital  operates,  any facility  regulated by
Article 28 of the New York Public  Health Law or any HMO regulated by Article 44
of the New York Public  Health Law,  without  the  approval of CHNLI;  provided,
however that this  agreement  by LIPHC is not meant to preclude  any  individual
investor  in LIPHC  from  acquiring,  establishing  or  investing  in any entity
regulated  under  Article 28 or Article 44 of the New York Public  Health Law or
from contracting to provide health care services to such regulated entities.

            (c) At  CHNLI's  request,  LIPHC  shall  cause MDLI to  establish  a
private label  medicaid/indigent  and a Medicare insurance program that identify
the  Diocese  of  Rockville  Centre as the  sponsor.  In  consideration  for the
establishment  of each such  program,  MDLI  participating  physicians  shall be
offered  the  right to  participate  in each  program  at  reimbursement  levels
comparable with Medicare  reimbursement levels, with appropriate  incentives and
disincentives.  The parties  hereto  further agree that such program shall enter
into an  agreement  with each of LIPHC and CHNLI,  pursuant  to which  LIPHC and
CHNLI shall perform various specified duties and provide consulting  services to
the program in exchange for a fee equal to one percent  (1%) of program  premium
revenue.  The fee payable by the program  shall be allocated  between  LIPHC and
CHNLI at a ratio of two-thirds to one-third (2/3 1/3).

            (d) CHNLI shall cause each CHNLI  Hospital to  cooperate  fully with
LIPHC,  MDLI or any  practice  associations  with respect to  credentialing  any
physician  on staff at a CHNLI  Hospital  who has applied to be a  participating
provider in MDLI, and shall facilitate, to the extent reasonably necessary, such
credentialing  process  by  making  available  any and  all  records  and  other
information in the possession of such CHNLI Hospital  regarding such physicians.
This obligation shall be an on-going obligation of CHNLI and CHNLI Hospitals.

            (e) The Diocese of Rockville  Centre and its sponsored  hospital and
health care entities shall offer,  on terms and conditions at least as favorable
to the  employee  as other  comparable  plans  being  offered by the  Diocese of
Rockville  Centre and its  sponsored  hospital  and health care  entities,  MDLI
health insurance  through the Diocesan Health Plan ("DHP"),  where DHP is acting
in a group purchasing capacity, to all of its employees no later than the end of
the first quarter of 1996 if MDLI has been  certified to operate an HMO prior to
that date, or as soon  thereafter  as is  practicable.  In connection  with such
offering,  MDLI shall agree to  establish  a  commercial  product,  on terms and
conditions  substantially  similar  to its  other  commercial  health  insurance
policies, that identifies the DHP, as well as MDLI, as the product's sponsors.

            (f) Any other  hospital or health  care entity  invited to secure an
equity ownership interest in MDLI (through CHNLI affiliation or otherwise) shall
offer,  on terms and  conditions  at least as favorable to the employee as other
comparable  plans being  offered by such entity,  MDLI  coverage to all eligible
employees of such member-hospitals no later than the end of the first quarter of
1996, or as soon thereafter as practicable.

            (g)  MDLI  shall  not  offer  medical   services  that  are  morally
objectionable  to the Diocese of Rockville  Centre as part of its basic  benefit
plan,  but only as a rider to ensure that CHNLI  Hospitals  shall not derive any
economic  benefit from the sale of such  coverage or from the  provision of such
services.  The parties  hereto agree that all necessary  steps shall be taken to
ensure that this provision is fully effectuated.


                                       14
<PAGE>

            (h) MDLI has adopted the operating  philosophy set forth on Schedule
8.9(h) hereto as its operating philosophy, and MDLI will conduct its business in
accordance therewith.

      8.10  HMO  Network.   MDLI  shall  assure  that  primary  care  physicians
(including   obstetricians  and   gynecologists)   shall  consist  of  at  least
twenty-eight   percent  (28%)  of  its  total   physician   network   (excluding
psychiatrists  and  podiatrists)  as such  network  shall  be  submitted  to the
Department in connection with the Application for Certification.

      8.11 Indemnity by MDLI and LIPHC.  MDLI and LIPHC will  indemnify,  defend
and hold harmless CHNLI and its successors and assigns, from and against any and
all claims, judgments, damages, losses, costs and expenses (including reasonable
attorneys'  fees) arising out of relating to any of the following  matters:  (i)
the inaccuracy of any  representation or warranty  contained in Sections 5 and 6
hereof; and (ii) the breach of any covenant,  agreement or obligation of MDLI or
LIPHC contained in this Agreement.

      8.12 Indemnity by CHNLI.  CHNLI will  indemnify,  defend and hold harmless
MDLI and LIPHC and their  successors  and assigns,  from and against any and all
claims,  judgments,  damages,  losses, costs and expenses (including  reasonable
attorneys'  fees) arising out of relating to any of the following  matters:  (i)
the inaccuracy of any  representation or warranty contained in Section 7 hereof;
and (ii) the breach of any covenant,  agreement or obligation of CHNLI contained
in this Agreement.

      9.  Forfeiture.  The  parties  hereto  agree  that if CHNLI  (a)  fails to
subscribe  for and  purchase  the  appropriate  number of Shares as set forth in
Section 2 hereof, (b) fails to remit the appropriate payments in connection with
such  subscriptions as set forth in Section 3 hereof,  or (c) otherwise fails to
purchase any of the Shares pursuant to this Agreement,  then, upon such failure,
this Agreement  shall  terminate and all of the covenants and agreements made by
LIPHC and MDLI in Section 8 hereof shall terminate and be of no further force or
effect,  and  CHNLI's  rights as a  shareholder  of MDLI shall be limited to the
powers  ordinarily  vested in a shareholder of a New York  corporation.  Without
limiting the  foregoing,  in the event CHNLI fails,  at any time, to comply with
and perform its obligations  under Sections 2 and/or 3 hereof,  CHNLI shall: (a)
not be  entitled  to nominate  the board  members or have such  members or other
representatives  participate  in board or  advisory  committees  pursuant to the
Shareholders Agreement; (b) not be entitled to enforce or otherwise exercise any
of  the  supermajority   voting  rights  accorded  CHNLI  in  the  Amendment  to
Certificate or Amended By-laws;  (c) not be entitled to continue the development
and  maintenance  of the hospital  network  servicing MDLI members in Nassau and
Suffolk  Counties,  New York, or in any expanded  service  area,  except for the
maintenance of any hospital network  then-existing within such areas; (d) not be
entitled to enforce the provisions of Section 8.5 of this Agreement;  (e) not be
retained by MDLI for the provision of any  management  services  pursuant to the
agreement  referenced in Section 8.6(b),  and such  agreement,  at least as such
relates to CHNLI, shall be terminated immediately; (f) not be granted any of the
rights to exclusivity provided by Section 8.7 hereof; and (g) not be entitled to
participate in any future  expansions of MDLI as provided by Section 8.8 hereof.
CHNLI  agrees  to take  all  actions  necessary  or  advisable,  in the sole and
complete  discretion of LIPHC or MDLI, to effectuate the foregoing  termination,
including the due execution and delivery of any and all  documents,  instruments
or certificates, and voting any shares of Common Stock held by CHNLI at the time


                                       15
<PAGE>

in favor of any and all matters relating to the forfeiture of any and all rights
vested in CHNLI arising out of the covenants and other  agreements made by LIPHC
in Section 8 hereof.

      10. Miscellaneous.

      10.1 Entire Agreement;  Successors and Assigns. This Agreement constitutes
the entire  agreement  between the parties  with  respect to the subject  matter
hereof,  and any previous or contemporaneous  agreement,  including all prior or
contemporaneous  correspondence and negotiations,  between MDLI, LIPHC and CHNLI
regarding the subject matter of this Agreement are superseded by this Agreement.
Subject to the exceptions specified in this Agreement,  the terms and conditions
of  this  Agreement  will  inure  to the  benefit  of and be  binding  upon  the
respective successors and permitted assigns of the parties hereto.

      10.2 Survival of Representations  and Warranties.  All representations and
warranties  and  agreements  made  by the  parties  in  this  Agreement  and all
statements  contained  in  any  certificate  or  document  delivered  at  or  in
connection  with the Initial Closing shall survive the execution and delivery of
this Agreement or such  certificate or other document,  the sale and purchase of
the Shares and any disposition thereof.

      10.3 Expenses.  LIPHC and CHNLI will each bear their  respective legal and
other  expenses  in  connection  with  the  transactions  contemplated  by  this
Agreement;  provided,  that in the event the  purchase of the MDLI Common  Stock
pursuant hereto does not occur for any reason, LIPHC shall be entitled to retain
that amount of the One Hundred Fifty Thousand Dollar ($150,000) deposit given by
CHNLI  to  LIPHC  in  connection  with  the  actions  contemplated  hereby  (the
"Deposit")  equal to fifty  percent (50%) of the legal fees incurred by LIPHC in
connection with the transactions  contemplated  hereby;  and provided,  further,
that in no respect is the  foregoing  intended to be or intended to be construed
as  liquidated  or  other  agreed-upon  damages  for the  non-occurrence  of the
purchase  by CHNLI of MDLI  Common  Stock  contemplated  hereby,  but rather the
foregoing is intended  only as an  agreement  between the parties to share legal
expenses  incurred in  connection  herewith in the event CHNLI does not purchase
the Shares.

      10.4 Department  Review.  The parties hereto further  acknowledge that the
transactions  contemplated hereunder are subject to review and approval, in some
instances  by certain  regulatory  agencies  of New York  State,  including  the
Department,  and agree that, to the extent required by such regulatory agencies,
