                   The purpose of the Supplemental  Executive Retirement Plan as
set forth herein and as the same may  hereafter be amended (the  "Plan"),  is to
secure  and  retain  the  services  of a select  group of  management  or highly

these Key Employees who have devoted extraordinary energies to HCSG.

                   GENERAL CREDITOR STATUS OF PARTICIPANTS.

                   (a)   TAX QUALIFICATION UNDER THE INTERNAL REVENUE CODE.

                         It is  intended  that the  Plan not be a  tax-qualified

1986, as amended (the "Code").

                   (b)   STATUS UNDER THE EMPLOYEE RETIREMENT INCOME

                         It is  intended  that  the  Plan  be  entitled  to  all
statutory  and  regulatory  exemptions  under  the  Employee  Retirement  Income
Security  Act of 1974,  as  amended  ("ERISA")  applicable  to plans  maintained
primarily for the purpose of providing deferred  compensation for a select group
of management or highly compensated employees.

                   (c)   CREDITOR STATUS OF PARTICIPANTS.

                         It is  intended  that  all  benefits  be paid  from the
general  assets of HCSG,  that  benefits  accrued under the Plan be unfunded for
ERISA and Code  purposes  until paid,  and that, as to unpaid  accrued  benefits
under the Plan, each Participant is an unsecured general creditor of HCSG.

terms of the Trust Agreement.

         Section 4.4   Payment of Benefits.

                       Within  ninety  (90) days of a  Participant's  Employment

of the month following the Participant's  Employment Termination Date. Shares of
Stock allocated to a Participant's Account shall be distributed in-kind.

         Section 4.5   Early Distribution of Benefits.

                       A  Participant   may  request  a   distribution   due  to
Unforeseeable   Emergency  by   submitting   a  written   request  to  the  Plan
Administrator  accompanied  by evidence to  demonstrate  that the  circumstances
being experienced qualify as an Unforeseeable  Emergency. The Plan Administrator
shall have the  authority  to require  such  evidence as it deems  necessary  to
determine if a  distribution  is  warranted.  If an  application  for a hardship
distribution  due to an  Unforeseeable  Emergency is approved,  the distribution
shall be limited to amounts  contributed by the Participant to the Plan pursuant
to Section 4.1 (and the  earnings  thereon)  and shall be further  limited to an
amount  sufficient  to meet the  emergency.  The allowed  distribution  shall be
payable in a method  determined  by the Plan  Administrator  as soon as possible
after approval of such  distribution.  "Unforeseeable  Emergency" means a severe
financial  hardship to the  Participant  resulting  from a sudden and unexpected
illness or accident of the  Participant  or of a dependent  of the  Participant,
loss  of  the  Participant's   property  due  to  casualty,   or  other  similar
extraordinary  and  unforeseeable  circumstances  arising  as a result of events
beyond the control of the Participant. The circumstances that will constitute an
"Unforeseeable  Emergency"  will depend upon the facts of each case, but, in any
event, payment may not be made if such hardship is or may be relieved:

                       (a)    Through reimbursement or compensation by insurance
or otherwise;


                                      -5-

                       (b)    By liquidation of the Participant's assets, to the
extent that  liquidation of such assets would not itself cause severe  financial
hardship, or

                       (c)    By cessation of Deferrals under the Plan.

                                   ARTICLE 5.

         Section 5.1   Designation by Participant.

                       Each Participant shall have the right to designate one or
more primary  Beneficiaries and one or more contingent  Beneficiaries to receive
the amount  represented  by his or her Account in the event of his or her death.
Beneficiary  designation(s) shall be made on the form attached hereto as Exhibit
"C" or on such other forms as may be prescribed by the Plan  Administrator.  The
Participant  shall have the right to revoke or change  Beneficiary  designations
from time to time,  and each such change shall  constitute  a revocation  of all
prior  designations.  No Beneficiary  designation  shall be effective  unless in
writing  and  delivered  to the Plan  Administrator  prior  to the  death of the
Participant.  Any such Beneficiary designation shall be subordinate to any court
order applicable to the Participant's interest in the Plan.

         Section 5.2   Default Provision.

                       If  a  Participant  dies  without  having   designated  a
Beneficiary, or if no such designated Beneficiary survives the Participant,  any
benefit  payable by reason of the death of the  Participant  shall be payable to
his or her surviving spouse,  or, if there is no surviving spouse, to his or her
surviving  children,  in equal shares. If the Participant dies with no surviving
spouse or children, any benefit shall be paid to the Participant's estate.

                         PLAN AMENDMENT AND TERMINATION


         Section 8.1   Amendment.

                       The provisions of the Plan may be amended at any time and
from time to time by the Board or any  subcommittee  thereof  or any  officer of
HCSG to whom the Board has delegated such authority. Any such amendment shall be
by written instrument, shall be communicated to the Participants,  and shall not
deprive the  Participant of any benefit  previously  earned or accrued as of the
date of the proposed amendment.

         Section 8.2   Plan Termination.

                       (a)    HCSG  reserves the right to terminate  the Plan in
whole  or in part at any  time and  without  notice  to any  person  or  entity.
Notwithstanding the foregoing, no such termination shall deprive the Participant
of any benefit earned or accrued as of the date of the proposed termination.  In
the event of any such  termination,  HCSG,  at its option,  may  distribute  the
Account  of all  Participants  as  though  the date of  termination  or  partial
termination of the Plan were the Participants'  Employment Termination Date, and
may  accelerate  the payment of benefits to all  distributees  then  receiving a
stream of  benefits  under the Plan,  or,  HCSG may elect to  continue  all such
streams of benefit  payments  and to defer the  distribution  of benefits to all
other potential distributees until a later date. A termination of the Plan shall
be duly  authorized by the Board or any  subcommittee  thereof or any officer of
HCSG to whom the Board has delegated such  authority.  Upon a termination of the
Plan for any reason,  each  Participant  shall become fully vested in all of the
Stock  contributed  and  allocated  to his or her  Account  pursuant  to Section
4.2(a).

                       (b)    In the event of a Change In  Control  (hereinafter
defined),  the Plan shall be  terminated  and the Accounts of all  Participant's
shall be  distributed  as  though  the date of  termination  were an  Employment
Termination Date for each Participant. A "Change In Control" shall occur if:

                              (i) (A)  any person (a "Person"),  as such term is
used in Sections  13(d) and 14(d) of the  Securities  Exchange  Act of 1934 (the
"Act")  and/or its wholly  owned  subsidiaries;  (B) any ESOP or other  employee
benefit plan of HCSG and any trustee or other fiduciary in such capacity holding
securities under such plan; (C) any corporation  owned,  directly or indirectly,
by the  shareholders  of HCSG in  substantially  the same  proportions  as their
ownership  of stock of HCSG;  or (D) any other  Person  who is as of the date of
this Plan  presently  an  executive  officer  of HCSG or any group of Persons of
which he voluntarily is a part) is or becomes the "beneficial owner" (as defined
in Rule 13d-3 under the Act),  directly or  indirectly,  of  securities  of HCSG
representing 30% or more of the combined voting power of HCSG's then outstanding
securities  or such lesser  percentage  of voting power but not less than 15% as
the Board of Directors of HCSG shall determine;


                                      -10-




                              (ii)     during any two-year  period  beginning on
the effective date of this Plan, Directors of HCSG in office at the beginning of
such period plus any new Director (other than a Director  designated by a Person
who has entered into an agreement  with HCSG to effect a transaction  within the
purview  of  subsections  (A) or (C)  hereof)  whose  election  by the  Board of
Directors or whose  nomination for election by HCSG's  shareholders was approved
by a vote of at least  two-thirds  of the  Directors  then  still in office  who
either  were  Directors  at the  beginning  of the period or whose  election  or
nomination for election was previously so approved shall cease for any reason to
constitute at least a majority of the Board of Directors; or

                              (iii)    HCSG's  shareholders  or HCSG's  Board of
Directors shall approve (A) any consolidation or merger of HCSG in which HCSG is
not the  continuing or surviving  corporation  or pursuant to which HCSG's Stock
would be converted into cash,  securities,  and/or other property,  other than a
merger of HCSG in which  holders of Stock  immediately  prior to the merger have
the  same  proportionate   ownership  of  Stock  of  the  surviving  corporation
immediately after the merger as they had in the Stock immediately before (B) any
sale,  lease,  exchange,  or other  transfer (in one  transaction or a series of
related transactions) of all or substantially all of the assets or earning power
of HCSG; or (C) the liquidation or dissolution of HCSG.

Participant  or any  Beneficiary  shall be subject to any claim of any  creditor
other than HCSG, and, in particular, to the fullest extent permitted by law, all
such payments,  benefits and rights shall be free from attachment,  garnishment,
trustee's  process or any other  legal or  equitable  process  available  to any
creditor of the  Participant or any  Beneficiary of the  Participant  other than
HCSG.  Neither  the  Participant  nor any  Beneficiary  shall  have the right to
alienate, anticipate, commute, pledge, encumber or assign any of the benefits or
payments which he or she may expect to receive, contingently or otherwise, under
the Plan or the Trust,  except that the  Participant  may  designate one or more

modification  thereof,  nor the creation of any fund, Trust or account,  nor the
admission  of any person to  participation  in the Plan,  nor the payment of any
benefits  shall be  construed as giving any Employee the right to be retained in
the service of HCSG;  and each Employee shall remain subject to retention in the
employ of HCSG and to  discharge  from such employ to the same extent and on the
same conditions as if the Plan was never adopted.

         Section 9.3   Severability of Provisions.

                       If any  provision  of the  Plan is  found  by a court  of
competent jurisdiction to be unlawful or unenforceable,  such provision shall be
deemed null and void,  and the balance of the Plan shall  continue in full force
and  effect,  as if such  unlawful  or  unenforceable  provision  had  not  been
included.

gender-neutral.   Accordingly,  except  where  otherwise  clearly  indicated  by
context,  the masculine,  feminine and neuter form of any word shall include all
other  gender-designating  forms,  the  singular  shall  include  the plural and

                       Any benefit  payable to or for the benefit of a minor, an
incompetent person or other person incapable of effectively  receipting therefor
shall be  deemed  paid  when  paid to such  person's  guardian  or to the  party
providing or  reasonably  appearing to provide for the care of such person,  and
such payments shall fully discharge the payor, the Plan Administrator,  HCSG and
all other parties with respect thereto.

         Section 9.8   Reliance on Data and Consents.

                       HCSG,  the Plan  Administrator  and all  other  person or
