                                ARTICLE I-PURPOSE

1.01. Purpose.

         The Healthcare  Services Group,  Inc. Employee Stock Purchase Plan (the
"Plan") is intended to provide a method whereby Employees of Healthcare Services
Group, Inc. and its subsidiary corporations (hereinafter referred to, unless the
context  otherwise  requires,  as the  "Company")  will have an  opportunity  to
acquire a proprietary  interest in the Company through the purchase of shares of
the Common Stock of the Company.  It is the intention of the Company to have the
Plan  qualify as an  "employee  stock  purchase  plan" under  Section 423 of the
Internal  Revenue Code of 1986, as amended (the "Code").  The  provisions of the
Plan  shall be  construed  so as to extend and limit  participation  in a manner
consistent with the requirements of that section of the Code.

                             ARTICLE II-DEFINITIONS

2.01. Committee.

         "Committee" shall mean the individuals described in Article XI.

 2.02. Common Stock.

         "Common Stock" means the voting common stock of the Company,  $0.01 par
value per share.

2.03. Earnings.

         "Earnings" shall mean total W-2 compensation earned by an Employee with
respect to services rendered to or on behalf of the Company.

2.04. Employee.

         "Employee" means any person who is customarily  employed on a full-time
or part-time  basis by the Company and is regularly  scheduled to work more than
20 hours per week.





2.05. Subsidiary Corporation.

         "Subsidiary  Corporation"  shall mean any present or future corporation
which (i) would be a  "subsidiary  corporation"  of the  Company as that term is
defined in Section 424 of the Code and (ii) is designated  as a  participant  in
the Plan by the Committee.


                    ARTICLE III-ELIGIBILITY AND PARTICIPATION

3.01. Initial Eligibility.

         Any  Employee  who shall  have  completed  two (2) years of  continuous
employment  with HCSG shall be eligible to  participate  in offerings  under the
Plan which commence on or after such period of employment has concluded.

3.02. Leave of Absence.

         For purposes of participation in the Plan, a person on leave of absence
shall be  deemed to be an  employee  for the  first  (90) days of such  leave of
absence and such employee's employment shall be deemed to have terminated at the
close of business on the 90th day of such leave of absence  unless such employee
shall have returned to regular  full-time or part-time  employment  (as the case
may be) prior to the close of  business  on such  90th day.  Termination  by the
Company of any employee's leave of absence, other than termination of such leave
of absence on return to full-time or part-time  employment,  shall  terminate an
employee's  employment  for all  purposes of the Plan and shall  terminate  such
employee's participation in the Plan and right to exercise any option.

3.03. Restrictions on Participation.

         Notwithstanding any provisions of the Plan to the contrary, no employee
shall be granted an option to purchase Common Stock under the Plan:

         (a) if,  immediately  after the grant,  such employee  would own stock,
and/or hold outstanding options to purchase stock,  possessing 5% or more of the
total combined voting power or value of all classes of stock of the Company (for
purposes of this paragraph,  the rules of Section 424(d) of the Code shall apply
in determining stock ownership of any employee); or

         (b) which permits his rights to purchase stock under all employee stock
purchase  plans (as described in Code Section 423) of the Company to accrue at a
rate which exceeds $25,000 in fair market value of the stock  (determined at the
time such  option is  granted)  for each  calendar  year in which such option is
outstanding.


                                      -2-

limitation described in Section 3.03(b).

specifically,  a participant may not alter the amount of his payroll  deductions
for that Offering.

5.04. Leave of Absence.

         If a participant  goes on a leave of absence,  such  participant  shall
have the right to elect:  (a) to withdraw the balance in his account pursuant to
Section  7.02,  (b) to  discontinue  contributions  to the  Plan  but  remain  a
participant  in the Plan, or remain a participant  in the Plan during such leave

the  participant  during  such leave of  absence  and  undertaking  to make cash
payments  to the  Plan at the end of each  payroll  period  to the  extent  that

participant's authorized Plan deductions.


                          ARTICLE VI-GRANTING OF OPTION

6.01. Number of Option Shares.

         On the  Commencement  Date of each Offering,  a participating  Employee

securities exchange; or

         (b) 85% of the closing  price of the stock on the Offering  Termination
Date or the nearest prior business day on which trading occurred on a recognized
securities exchange.


                                      -4-

         If the Common Stock of the Company is not admitted to trading on any of
the  aforesaid  dates for which  closing  prices of the  Common  Stock are to be
determined,  then reference shall be made to the fair market value of the Common
Stock on that  date,  as  determined  on such basis as shall be  established  or
specified for the purpose by the Committee.


                         ARTICLE VII-EXERCISE OF OPTION

7.01. Automatic Exercise.

         Unless a participant gives written notice to the Company as hereinafter
provided,  his option for the  purchase of stock with  payroll  deductions  made
during any offering will be deemed to have been exercised  automatically  on the
Offering  Termination Date applicable to such offering,  for the purchase of the
number of full shares of stock which the accumulated  payroll  deductions in his
account at that time will  purchase at the  applicable  option price (but not in
excess of the  number  of shares  for which  options  have been  granted  to the
employee  pursuant to Section 6.01),  and any excess in his account at that time
will be returned to him.

7.02. Withdrawal of Account.

         By written notice to the Human Resources  Department of the Company, at
any time prior to the Offering  Termination  Date applicable to any Offering,  a
participant may elect to withdraw all the accumulated  payroll deductions in his
account at such time.

7.03. Fractional Shares.

         Fractional shares will not be issued under the Plan and any accumulated
payroll deductions which would have been used to purchase fractional shares will
be returned to any employee  promptly  following the termination of an Offering,
without interest.

7.04. Transferability of Option.

         During a participant's lifetime, options held by such participant shall
be exercisable only by that participant.

Offering,  the Company will deliver to each  participant,  as  appropriate,  the
stock purchased upon exercise of his option.

                             ARTICLE VIII-WITHDRAWAL

8.01. In General.


                                      -5-

deductions  credited to his account under the Plan at any time by giving written
notice  to  the  Human  Resources   Department  of  the  Company.   All  of  the
participant's  payroll  deductions  credited to his account  will be paid to him
promptly  after  receipt of his  notice of  withdrawal,  and no further  payroll
deductions  will be made from his pay during such Offering.  The Company may, at
its option,  treat any  attempt to borrow by an employee on the  security of his
accumulated  payroll deductions as an election,  under Section 3.02, to withdraw
such deductions.

8.02. Effect on Subsequent Participation.

         A  participant's  withdrawal from any Offering will not have any effect
upon his eligibility to participate in any succeeding Offering or in any similar
plan which may hereafter be adopted by the Company.

8.03. Termination of Employment.

         Upon  termination  of the  participant's  employment  for  any  reason,
including  retirement (but excluding death while in the employ of the Company or
continuation  of a leave of absence  for a period  beyond 90 days),  the payroll
deductions  credited to his account  will be returned to him, or, in the case of
his death  subsequent to the  termination  of his  employment,  to the person or
persons entitled thereto under Section 12.01.

8.04. Termination of Employment Due to Death.

         Upon termination of the participant's  employment because of his death,
his  beneficiary (as defined in Section 12.01) shall have the right to elect, by
written notice given to the Human  Resources  Department of the Company prior to
the earlier of the Offering  Termination  Date or the  expiration of a period of
sixty  (60)  days  commencing  with  the date of the  death of the  participant,
either:

         (a)  to  withdraw  all  of  the  payroll  deductions  credited  to  the
participant's account under the Plan, or

         (b) to exercise the  participant's  option for the purchase of stock on
the Offering Termination Date next following the date of the participant's death
for the  purchase of the number of full  shares of stock  which the  accumulated
payroll deductions in the participant's account at the date of the participant's
death will  purchase  at the  applicable  option  price,  and any excess in such
account will be returned to said beneficiary, without interest.


                                      -6-


         In the event  that no such  written  notice of  election  shall be duly
received by the office of the Human  Resources  Department  of the Company,  the
beneficiary shall automatically be deemed to have elected, pursuant to paragraph
(b), to exercise the participant's option.

8.05. Leave of Absence.

         A participant on leave of absence  shall,  subject to the election made
by such participant pursuant to ?5.04,  continue to be a participant in the Plan
so long as such participant is on continuous leave of absence. A participant who
has been on leave of absence for more than 90 days and who  therefore  is not an
employee for the purpose of the Plan shall not be entitled to participate in any
offering  provisions  of the  Plan,  unless a  participant  on leave of  absence
returns to regular  full-time  or part-time  employment  with the Company at the
earlier  of: (a) the  termination  of such leave of absence or (b) three  months
from the 90th day of such leave of absence, such participant's  participation in
the Plan shall terminate on whichever of such dates first occurs.

                               ARTICLE IX-INTEREST

9.01. Payment of Interest

         No interest  will be paid or allowed on any money paid into the Plan or
credited to the account of any participant.  Moreover, no interest shall be paid

the provisions of Sections 7.02, 8.01, 8.03, 8.04 or 10.01.

                                 ARTICLE X-STOCK

         The  maximum  number of shares  which  shall be issued  under the Plan,
subject to adjustment upon changes in  capitalization of the Company as provided
in Section 12.04 shall be 200,000  shares in each annual  Offering plus, in each
Offering all unissued shares from prior  Offerings,  whether offered or not, not
to exceed 800,000  shares for all  Offerings.  If the total number of shares for
which options are exercised on any Offering  Termination Date in accordance with
Article VI exceeds the maximum number of shares for the applicable offering, the
Company shall make a pro-rata  allocation  of the shares  available for delivery
and distribution in an nearly a uniform manner as shall be practicable and as it
shall determine to be equitable,  and the balance of payroll deductions credited
to the  account of each  participant  under the Plan shall be returned to him as
promptly as possible.

10.02. Participant's Interest in Option Stock.

         The  participant  will have no interest in stock  covered by his option
until such option has been exercised.

                                      -7-

10.03. Registration of Stock.

         Stock  to  be  delivered  to a  participant  under  the  Plan  will  be
registered in the name of the participant,  or, if the participant so directs by
written  notice to the Human  Resources  Department  of the Company prior to the
Offering  Termination Date applicable  thereto,  in the names of the participant
and one such other  person as may be  designated  by the  participant,  as joint
tenants  with rights of  survivorship  or as tenants by the  entireties,  to the
extent permitted by applicable law.

10.04. Restrictions on Exercise.

         The Board of Directors may, in its  discretion,  require as a condition
to the  purchase  of Common  Stock  hereunder  that the  shares of Common  Stock
reserved  for purchase  hereunder  shall have been duly  listed,  upon  official
notice of issuance, upon a stock exchange, and that either:

         (a) a  Registration  Statement  under the  Securities  Act of 1933,  as
amended, with respect to said shares shall be effective, or

         (b) the participant shall have represented at the time of purchase,  in
form and  substance  satisfactory  to the Company,  that it is his  intention to
purchase the shares for investment and not for resale or distribution.


                            ARTICLE XI-ADMINISTRATION

11.01. Appointment of Committee

         The Board of Directors  shall appoint a committee (the  "Committee") to
administer  the Plan,  which shall consist of no fewer than three (3) members of
the Board of Directors.

11.02. Authority of Committee

         Subject to the express provisions of the Plan, the Committee shall have
plenary  authority  in its  discretion  to  interpret  and  construe any and all
provisions of the Plan, to adopt rules and  regulations  for  administering  the
Plan,  and to make all other  determinations  deemed  necessary or advisable for
administering  the Plan. The Committee's  determination on the foregoing matters
shall be conclusive.


                                      -8-

11.03. Rules Governing the Administration of the Committee

         The Board of  Directors  may from time to time  appoint  members of the
Committee in substitution for or in addition to members previously appointed and
may fill vacancies,  however caused, in the Committee.  The Committee may select
one of its members as its Chairman and shall hold its meetings at such times and
places as it shall deem advisable and may hold telephonic  meetings.  A majority
of its members shall constitute a quorum.  All  determinations  of the Committee
shall be made by a majority of its members. The Committee may correct any defect
or omission or reconcile any inconsistency in the Plan, in the manner and to the
extent it shall deem desirable. Any decision or determination reduced to writing
and  signed by a majority  of the  members  of the  Committee  shall be as fully
effective as if it had been made by a majority vote at a meeting duly called and
held.  The  Committee  may  appoint a  secretary  and shall  make such rules and
regulations for the conduct of its business as it shall deem advisable.


                            ARTICLE XII-MISCELLANEOUS

12.01. Designation of Beneficiary.

         A participant may file a written designation of a beneficiary who is to
receive any stock and/or cash. Such designation of beneficiary may be changed by
the participant at any time by written notice to the Human Resources  Department
of the Company.  Upon the death of a participant and upon receipt by the Company
of proof of identity and existence at the  participant's  death of a beneficiary
validly  designated by him under the Plan,  the Company shall deliver such stock
and/or cash to such beneficiary.  In the event of the death of a participant and
in the absence of a beneficiary  validly designated under the Plan who is living
at the time of such  participant's  death,  the company shall deliver such stock
and/or cash to the executor or  administrator  of the estate of the participant,
or if no such executor or administrator  has been appointed (to the knowledge of
the Company), the Company, in its discretion, may deliver such stock and/or cash
to the spouse or to any one or more dependents of the participant as the Company
may designate.  No beneficiary  shall,  prior to the death of the participant by
whom he has been designated,  acquire any interest in the stock or cash credited
to the participant under the Plan

12.02. Transferability.

         Neither payroll deductions credited to a participant's  account nor any
rights  with regard to the  exercise of an option or to receive  stock under the
Plan may be assigned, transferred,  pledged, or otherwise disposed of in any way
by the participant  other than by will or the laws of descent and  distribution.
Any such attempted  assignment,  transfer,  pledge or other disposition shall be
without  effect,  except  that the  Company may treat such act as an election to
withdraw funds in accordance with Section 7.02.

12.03. Use of Funds.

         All payroll deductions  received or held by the Company under this Plan
may be used by the Company for any  corporate  purpose and the Company shall not
be obligated to segregate such payroll deductions.


                                      -9-

12.04. Adjustment Upon Changes in Capitalization.

         (a) If, while any options are  outstanding,  the outstanding  shares of
Common Stock of the Company have  increased,  decreased,  changed  into, or been
exchanged for a different  number or kind of shares or securities of the Company
through reorganization, merger, recapitalization, reclassification, stock split,
reverse  stock  split or  similar  transaction,  appropriate  and  proportionate
adjustments  may be made by the  Committee  in the number  and/or kind of shares
which are  subject  to  purchase  under  outstanding  options  and on the option
exercise price or prices applicable to such outstanding options. In addition, in
any such event,  the number  and/or  kind of shares  which may be offered in the
Offerings described in Article IV hereof shall also be proportionately adjusted.
No  adjustments  shall be made for stock  dividends.  For the  purposes  of this
Paragraph,  any distribution of shares to shareholders in an amount  aggregating
20% or more of the  outstanding  shares  shall be  deemed a stock  split and any
distributions  of shares  aggregating  less than 20% of the  outstanding  shares
shall be deemed a stock dividend.

         (b) Upon the  dissolution  or  liquidation  of the  Company,  or upon a
reorganization,  merger  or  consolidation  of the  Company  with  one  or  more
corporations as a result of which the Company is not the surviving  corporation,
or upon a sale of  substantially  all of the property or stock of the Company to
another  corporation,  the holder of each option then outstanding under the Plan
will  thereafter be entitled to receive at the next Offering  Termination  Date,
upon the exercise of such option for each share as to which such option shall be
exercised,  as nearly as  reasonably  may be  determined,  the cash,  securities
and/or  property which a holder of one share of the Common stock was entitled to
receive upon, and at the time of, such transaction. The Board of Directors shall
take such steps in  connection  with such  transactions  as the Board shall deem
necessary to assure that the  provisions of this Section 12.04 shall  thereafter
be applicable,  as nearly as reasonably  may be  determined,  in relation to the
said cash,  securities  and/or  property  as to which such holder of such option
might thereafter be entitled to receive.

12.05. Amendment and Termination.

         The Board of  Directors  shall have  complete  power and  authority  to
terminate  or amend the Plan;  provided,  however,  that the Board of  Directors
shall not,  without the  approval of the  stockholders  of the  Corporation  (i)
increase  the maximum  number of shares  which may be issued  under any Offering
(except pursuant to Section 12.04);  (ii) amend the requirements as to the class
of employees  eligible to purchase stock under the Plan or permit the members of
the Committee to purchase stock under the Plan. No termination, modification, or
amendment  of the Plan may,  without the  consent of an employee  then having an
option  under the Plan to purchase  stock,  adversely  affect the rights of such
employee under such option.

12.06. Effective Date.

         The Plan shall  become  effective  as of  January  1, 2000,  subject to
approval  by the  holders  of the  majority  of the  Common  Stock  present  and
represented at a special or annual meeting of the shareholders held on or before
June  30,  2000.  If the Plan is not so  approved,  the Plan  shall  not  become
effective.

12.07. No Employment Rights.

         The Plan does not,  directly  or  indirectly,  create any right for the
benefit of any  employee or class of  employees to purchase any shares under the
Plan,  or create in any employee or class of employees any right with respect to
continuation  of  employment  by the  Company,  and it shall  not be  deemed  to
interfere in any way with the Company's right to terminate, or otherwise modify,
an employee's employment at any time.

12.08. Effect of Plan.

         The  provisions  of the Plan shall,  in accordance  with its terms,  be
binding  upon,  and inure to the benefit  of, all  successors  of each  employee
participating in the Plan, including, without limitation, such employee's estate
and the executors,  administrators or trustees thereof,  heirs and legatees, and
any  receiver,  trustee in  bankruptcy  or  representative  of creditors of such
employee.

12.09. Governing Law.

         The law of the  Commonwealth  of  Pennsylvania  will govern all matters
relating to this Plan except to the extent it is  superseded  by the laws of the
United States.
