     A. The  Board of  Directors  of the  Company  (the  "Board")  considers  it
essential to the best interests of the Company and its stockholders that its key
management   personnel  be  encouraged  to  remain  with  the  Company  and  its

Company's principal businesses, subsidiaries, divisions or functions.

     C. The Board believes the Executive has made and is expected to continue to
make valuable contributions to the productivity and profitability of the Company
and its subsidiaries.

     D. The Board believes it imperative  that the Company and the Board be able
to rely upon the  Executive  to  continue in his or her  position,  and that the
Company and the Board be able to receive and rely upon his or her advice,  if so
requested,  as to the best interests of the Company and its stockholders without
concern that he or she might be  distracted  by the personal  uncertainties  and
risks  created  by events  that are not within  such  person's  control,  and to
encourage the Executive's full attention and dedication to the Company.

     E. The Board, upon the recommendation of the Compensation  Committee of the

                              TERMS AND CONDITIONS:

     NOW,  THEREFORE,  to assure the Company and its  subsidiaries  that it will

Executive and the  availability  of the Executive's  advice and counsel,  and to

subsidiaries,  and for other good and valuable  consideration,  the adequacy and
sufficiency  of which are hereby  acknowledged,  the Company  and the  Executive
agree as follows:

     1. CERTAIN DEFINITIONS

     For  purposes  of this  Agreement,  the  following  terms  shall  have  the
following meanings:

          (a) "Cause" means:

connection with his or her employment by the Company, constituting a felony 
under applicable law;

               (ii)  any  act or acts of  gross  dishonesty  or  gross  
misconduct  on the Executive's  part which result or are intended to result  
directly or indirectly in gain or personal advantage or enrichment at the 
expense of the Company or its subsidiaries; or

               (iii) any  violation  by the  Executive  of his or her  
obligations  to the Company  or  its  subsidiaries  which  violation  is  
demonstrably  willful  and deliberate on the  Executive's  part and which 
results in material damage to the business or reputation of the Company or its 
subsidiaries.

     Notwithstanding the foregoing,  the employment of the Executive shall in no
event  be  deemed  to  have  been  terminated  by the  Company  for  "Cause"  if
termination  of his or her  employment  by the Company  took  place:  (A) as the
result of bad judgment or  negligence  on the part of the  Executive  other than
gross negligence; (B) because of an act or omission believed by the Executive in
good faith to have been in or not  opposed to the  interests  of the Company and
its  subsidiaries;   (C)  for  any  act  or  omission  in  respect  of  which  a
determination  could  properly  be made that the  Executive  met the  applicable
standard of conduct  prescribed for  indemnification or reimbursement or payment
of expenses under the Certificate of  Incorporation  or bylaws of the Company or
the laws of the state of incorporation of the Company, in each case as in effect

such  commission  or omission have been known to the President of the Company or
to a member  of the  Board  (other  than the  Executive,  if he or she is then a
member of the Board),  in which case more than twelve (12) calendar  months from
the  date  that  the  commission  of such  act or  such  omission  was or  could
reasonably  have been so known;  or (E) as the result of a continuing  course of
action  which  commenced  and was or could  reasonably  have  been  known to the
President of the Company or to a member of the Board (other than the  Executive)
more than twelve calendar months prior to the Executive having been given Notice
of Termination.

          (b) "Change in Control" means and shall be deemed to have occurred 
upon:

securities of the Company or any successor of the Company;

               (ii) when individuals who, as of the date hereof, constitute the 
Board (the "Incumbent Board") cease for any reason to constitute at least a 
majority of the Board,  provided  that any person who becomes a director  
subsequent to the date hereof whose election or nomination  for election by the
Company's  stockholders was approved by a vote of at least a majority of the 
directors  then  comprising the Incumbent Board (other than an individual whose
initial assumption of office is in connection with an actual or threatened 
election  contest relating to the election of the directors of the Company,  as
such terms are used in Rule 14a-11 of  Regulation  14A under the  Exchange  Act)
shall be, for purposes  of this definition,  considered  as though such  person
were a member of the Incumbent Board;

               (iii) approval by the stockholders of the Company of the 
liquidation of the Company or any sale or disposition,  or series of related 
sales or dispositions, of 50% or more of the assets or earning power of the 
Company; or

               (iv) approval by the stockholders of the Company and consummation

Company is a party and as a result of which the persons who were stockholders 
of the Company immediately  prior to the  effective  date of the  merger  or  
consolidation  or statutory share exchange shall have beneficial ownership of 
less than 50% of the combined voting power in the election of directors of the 
surviving  corporation following the effective date of such merger or  
consolidation or statutory share exchange.

     Notwithstanding the foregoing,  a "Change in Control" shall not include (A)
the sale or other  transfer of  beneficial  ownership of Class B Common Stock of
the Company by NYLIFE Healthcare Management, Inc. to (or any acquisition of such
beneficial  ownership by) an affiliate thereof,  including,  without limitation,
New York  Life  Insurance  Company  or any  holding  company  formed by any such
affiliate,  or (B) an isolated sale,  spin-off,  joint venture or other business
combination by the Company, which involves one or more divisions or subsidiaries
of the Company and is approved by a majority vote of the Incumbent Board.

     "Good Reason" means the occurrence of any one or more of the following:

hereunder or thereunder, in any such case, after receipt of written notice of 
such breach or failure from the Executive and the failure by the Company to cure
such breach or failure within fifteen (15) business days after receipt of such 
notice;

               (ii) The Company's requiring the Executive to be based at any 
office or location more than 50 miles from his or her  then-current  office or 
location at which he or she is then  based,  except for travel  reasonably  
required  in the performance of the Executive's responsibilities to the extent
substantially consistent  with  the  Executive's  business  travel  obligations
prior to such required  relocation,  either (A) within three (3) years of any 
prior relocation at the Company's request(other than a relocation in connection
with his or her initial  employment by the Company) or (B) within two (2) years
following any Change in Control;

               (iii) The assignment to the Executive of any duties inconsistent
in any material adverse respect with his or her position, authority or 
responsibilities with the Company and its subsidiaries  immediately prior to 
such assignment, or any other material adverse change in such position, 
including titles, authority, or responsibilities, as compared with the 
Executive's position immediately prior to such change;

               (iv) A material  reduction by the Company in the amount of the  
Executive's base salary or target annual bonus  compensation  paid or payable as
compared to that which was paid or made available to the Executive immediately 
prior to such reduction; or

               (v) The failure by the Company to continue to provide the
Executive with substantially  similar  perquisites  or benefits the  Executive

long-term  incentive compensation programs), such as any of the Company's 
pension, savings, vacation, life insurance, medical, health and accident, or 
disability plans in which he or she  was participating at the time of any such
discontinuation (or, alternatively, if such plans are amended, modified or 
discontinued, substantially similar equivalent benefits thereto in the 
aggregate), or the taking of any action by the Company which would directly or  
indirectly cause such benefits to be no longer  substantially equivalent in the
aggregate to the benefits in effect immediately prior to taking such action;  
provided, that any amendment,  modification or discontinuation of any plans or 
benefits referred to in this Subsection (v) that generally affect substantially 
all domestic salaried employees of the Company shall not be deemed to constitute
Good Reason.

     2. OBLIGATIONS OF THE COMPANY UPON TERMINATION; CONDITIONS TO THE COMPANY'S
OBLIGATIONS; ACKNOWLEDGMENTS AND AGREEMENTS OF THE EXECUTIVE

          (a) DEATH OR DISABILITY.If the Executive's employment is terminated by
reason of the  Executive's  death or disability,  this Agreement shall terminate
without further  obligations to the  Executive's  legal  representatives  or the
Executive,  as the case may be, under this  Agreement.  For the purposes of this
Agreement,  "disability"  shall have the same  definition  as  contained  in any
long-term  disability  insurance  plan or  program  of the  Company in which the
Executive is  participating at the time of termination of his or her employment.
If the Executive is not so  participating  or is  participating in more than one
such  plan  or  program  at the  time of  termination,  "disability"  means  the
Executive's  inability  by  reason  of  illness  or  other  physical  or  mental
disability to perform the principal  duties required by the position held by the
Executive at the  inception of such illness or  disability  for any  consecutive
180-day  period.  A  determination  of  "disability"  shall  be  subject  to the
certification  of a qualified  medical  doctor  agreed to by the Company and the
Executive  or,  in  the  Executive's  incapacity  to  designate  a  doctor,  the
Executive's legal representative.  If the Company and the Executive cannot agree
on the  designation of a doctor,  each party shall nominate a qualified  medical
doctor and the two doctors shall select a third  doctor;  the third doctor shall
make the determination as to "disability."

          (b) TERMINATION BY THE COMPANY FOR CAUSE;TERMINATION BY THE EXECUTIVE
OTHER THAN FOR GOOD Reason. If the Executive's employment shall be terminated by
the  Company  for Cause or by the  Executive  other than for Good  Reason,  this
Agreement  shall terminate  without further  obligations to the Executive on the
Termination Date.

          (c) TERMINATION BY THE COMPANY OTHER THAN FOR CAUSE;TERMINATION BY THE
EXECUTIVE  FOR GOOD  REASON.  If the Company  shall  terminate  the  Executive's
employment  other than for Cause,  or the  employment of the Executive  shall be
terminated by the Executive  for Good Reason,  the Executive  shall be entitled,
subject to Sections 2(e) and 4 hereof, to a severance benefit in an amount equal
to (i) twelve (12) times the monthly  base  salary  being paid to the  Executive
immediately  prior to the  Termination  Date plus  (ii) an  amount  equal to the
product  of (x) the  Executive's  Bonus  Potential  for the  year in  which  the
Termination Date occurs (the  "Termination  Year") multiplied by (y) the average
percentage of the Bonus Potential earned by the Executive for the three (3) full
years immediately  preceding the Termination Year (or such shorter period if the
Executive  was  employed  by the  Company for less than three (3) full years and
received or was eligible to receive a bonus during such  period),  which product
shall be prorated for the portion of the Termination Year in which the Executive
was employed by the Company.  For purposes of this Agreement,  "Bonus Potential"
shall mean the maximum bonus amount the Executive  could receive under the terms
of his or her annual bonus letter or, if no bonus letter is issued, otherwise in
accordance  with the terms of the  Company's  bonus  plan then in effect for all
senior executives of the Company. If a maximum bonus amount is not determinable,
then the Compensation  Committee shall determine in good faith the amount of the
bonus the Executive could reasonably have been expected to have received for the
Termination  Year,  and such  determination  shall be final and  binding  on all
parties;  provided  that,  for purposes of this  Agreement,  if a maximum  bonus
amount  is not  determinable,  in no event  shall  such  amount be less than the
average of the actual bonus payment  received by the Executive in respect of the
three (3) full years immediately preceding the Termination Year (or such shorter
period if the  Executive  was  employed  by the  Company for less than three (3)
years).

         (d)PAYMENTS IN INSTALLMENTS.The Company shall pay the severance benefit
required  under  Section  2(c) hereof,  without  interest  thereon,  in four (4)
substantially  equal  quarterly  installments,  payable on the first day of each
calendar  quarter,  with the first  such  installment  payable in the first full
calendar quarter  commencing  twenty-eight (28) days after the date on which the
Executive  complies with Section  2(e)(i) and, if applicable,  Section  2(e)(ii)
below, subject to applicable withholding and employment taxes.

          (e) CONDITIONS TO RECEIPT OF PAYMENTS. As a condition to the Company's
obligation to pay the severance benefit hereunder, the Executive must deliver to
the Company the following:

               (i) No later than thirty (30) days after the  Termination  Date,
a general release  and  acknowledgment  in the form  attached  hereto  as  
EXHIBIT  A (the "General Release"); and

               (ii) An acknowledgement and agreement in a form reasonably  
satisfactory to the  Company  that  the  noncompetition  provisions  of  the  
Nondisclosure  and Noncompetition  Agreement  between the  Executive  and the 
Company,  in the form    previously executed by the Executive,  will be 
effective for a period of one (1) year  commencing  on the  Termination  Date, 
notwithstanding  the fact that the Executive's  employment with the Company may 
have been terminated by the Company other than for Cause; provided,  however, 
that the foregoing  acknowledgment and agreement shall not be required if the  
Termination  Date occurs within eighteen (18) months following a Change of 
Control.

          (f)  ACKNOWLEDGEMENTS  OF THE  EXECUTIVE.  The Executive acknowledges
and agrees that:

               (i) The provisions of Section 2(e) are reasonable and enforceable
because, among other things, (1) the Executive will be receiving  compensation
under this Agreement and (2) there are many other areas in which, and companies
for which, the Executive could work in view of the Executive's background, and 
Section 2(e)therefore does not impose any undue hardship on the Executive;

               (ii) The  provisions of the Nondisclosure and Noncompetition 
Agreement, including by way of its applicability hereunder in the event of a 
termination of the Executive's employment without Cause, are reasonable and 
enforceable in view of the Company's legitimate interests in protecting its 
confidential information and customer goodwill and the limitations contained 
therein on the duration and geographic scope of, and activities covered by,such
provisions; and

               (iii) In deciding to sign this Agreement, the Executive has not
relied upon any  statements  or promises  by the Company  other than those set 
forth in this Agreement, and the Executive understands that this Agreement 
contains the entire agreement between the parties.

          (g) ADDITIONAL AGREEMENTS.

               (i) The Executive  represents that he or she has not, and agrees 
that he or she will not,  in any way  disparage  the  Company  or its  current  
and  former officers, directors and employees, or make or solicit any comments,
statements, or the like to the media or to others that may be considered to be 
derogatory or detrimental to the good name or business reputation of any of the
aforementioned parties or entities;

               (ii)  The  Executive  further  agrees  that he or she  will not 
at any time discuss any matter  concerning  the Company with anyone  adverse or
potentially adverse to the Company on any matter, including, without limitation,
employment claims or customer  claims,  without the prior  written  consent of 
the Company. However, if required by a  governmental  regulatory  agency or  
self-regulatory agency to provide testimony or information  regarding the 
Company, the Executive will cooperate with said regulatory agency. If compelled
to testify by a validly served  subpoena  or  by  regulatory  authority,   the 
Executive  will  testify truthfully as to all matters  concerning his or her 
employment with the Company. If  a  regulatory  agency  or  self-regulatory  
agency  contacts  the  Executive regarding the Company or if the Executive  
receives a subpoena or other court or legal  process  relating  in any way to 
the Company, or any present or former Company  customer or employee, the 
Executive immediately will give the Company prior  written  notice  and  shall 
make himself or herself available to be interviewed concerning the subject 
matter of such contact; and

               (iii) The  Executive  agrees to cooperate  with and make himself
or herself readily  available  to the  Company or its General  Counsel,  as the
Company may reasonably  request,  to  assist  it in  any  matter,  including  
litigation or proceedings or potential litigation or proceedings, over which the
Executive may have knowledge,  information or expertise,  provided,  however, 
that the Company shall pay the reasonable out-of-pocket expenses of the 
Executive in performing his or her obligations under this Section 2(g)(iii).

     3. NOTICE OF TERMINATION

     For  purposes  of  this  Agreement,  any  termination  of  the  Executive's
employment by the Company as  contemplated by Sections 2(a) or 2(b) hereof or by
the Executive as  contemplated  by Section 2(c) hereof shall be  communicated by
written  "Notice of  Termination"  to the other  party  hereto.  Any  "Notice of
Termination" shall set forth (a) the effective date of termination (for purposes
of determining the Executive's  entitlement to benefits hereunder),  which shall
not be less than  fifteen  (15) or more than thirty (30) days after the date the
Notice of Termination is delivered (the  "Termination  Date");  (b) the specific
provision in this Agreement relied upon; and (c) in reasonable  detail the facts
and   circumstances   claimed   to   provide  a  basis  for  such   termination.
Notwithstanding  the foregoing,  if within fifteen (15) days after any Notice of
Termination is given,  the party  receiving such Notice of Termination  notifies
the other party that a good faith dispute exists concerning the termination, the
effective  date of  termination  for  purposes of  determining  the  Executive's
entitlement  to  benefits  under this  Agreement  shall be the date on which the
dispute is finally  determined in accordance  with the  provisions of Section 12
hereof. In the case of any good faith dispute as to the Executive's  entitlement
to benefits under this Agreement  resulting from any  termination by the Company
for which the Company does not deliver a Notice of  Termination,  the  effective
date of termination for purposes of determining  the Executive's  entitlement to
benefits under this Agreement  shall be the date on which the dispute is finally
determined  in  accordance  with the  provisions  of Section  12 hereof.  If the
parties do not dispute the Executive's  entitlement to benefits  hereunder,  the
effective date of termination shall be the Termination Date.

     4. MITIGATION

     The  Executive  is not  required  to seek  other  employment  or  otherwise
mitigate the amount of any  payments to be made by the Company  pursuant to this
Agreement;  provided,  however,  that any amounts  earned by the Executive  from
employment  with another  employer  prior to the final payment by the Company of
amounts payable  hereunder will reduce any amounts or benefits due the Executive
pursuant to this  Agreement on a  dollar-for-dollar  basis;  provided,  further,
however,  that no such  reduction  shall be  required  or made in the  event the
Termination  Date  occurs  within  eighteen  (18)  months  following a Change in
Control.

     5. BREACH

     In the  event  of a  breach  by  the  Executive  of any of the  Executive's
agreements  in Section  2(e) or Section  2(g) hereof  (including a breach of any
agreements in the General  Release or in the  Nondisclosure  and  Noncompetition
Agreement),  the Executive shall pay to the Company all amounts previously paid,
allocated,  accrued or provided by the Company to the Executive pursuant to this
Agreement and the Company shall be entitled to discontinue  the future  payment,
allocation,  accrual  or  provision  of  any  amounts  or  benefits  under  this
Agreement.  The  Executive  recognizes  and agrees  that it is the intent of the
parties that neither this Agreement nor any of its provisions shall be construed
to  adversely  affect any rights or remedies  that the  Company  would have had,
including, without limitation, the amount of any damages for which it could have
sought recovery,  had this Agreement not been entered into. Without limiting the
generality of the foregoing, nothing in this Section 5 or any other provision of
this Agreement shall limit or otherwise affect the Company's right to seek legal
or equitable  remedies it may otherwise have, or the amount of damages for which
it may seek  recovery,  resulting from or arising out of statutory or common law
or any Company policies relating to fiduciary duties,  confidential  information
or trade secrets.

     6. SUCCESSORS

          (a) The Company shall require any successor (whether direct or 
indirect, by purchase, merger, consolidation or otherwise) to all or 
substantially all of the business  and/or  assets of the Company,  by agreement
to assume  expressly  and agree to perform  this  Agreement in the same manner 
and to the same extent that the  Company  would be required  to perform it if no
such  succession  had taken place. For  purposes  of this  Agreement, "Company"
shall mean the Company as hereinbefore  defined  and  any  successor  to its  
business  and/or  assets  as aforesaid.

         (b) This Agreement shall inure to the benefit of and be enforceable by
the Executive's personal or legal representatives, executors, administrators,
successors, heirs, distributees, beneficiaries, devises and legatees. If the
Executive should die while any amounts are payable to him or her hereunder, all
such amounts, unless otherwise provided herein, shall be paid in accordance with
the terms of this Agreement to the Executive's devisee, legatee, beneficiary or
other designee or, if there be no such designee, to the Executive's estate.

2(g)  hereof) or to preserve the status quo pending resolutions of Disputes 
hereunder;  and PROVIDED FURTHER,  that  resolution  of Disputes  with respect 
to claims by third parties shall be deferred until judicial proceedings with 
respect thereto are concluded. Either party to this  Agreement  (each a "Party" 
and together the "Parties") may commence  proceedings  hereunder  by  delivery
of written  notice  providing  a reasonable  description  of the Dispute to the
other, including a reference to this Section (the "Dispute Notice").

          (b) NEGOTIATIONS BETWEEN PARTIES.The Parties shall first attempt in
good faith to resolve promptly any Dispute by good faith negotiations. Not later
than three (3) business days after delivery of the Dispute Notice, the Company
shall appoint an officer to meet with the Executive or his or her representative
at a reasonably acceptable time and place,and thereafter as such representatives
deem reasonably  necessary.  The Parties shall exchange relevant  non-privileged
information and endeavor to resolve the Dispute. Prior to any such meeting, each
Party or  representative  shall advise the other as to any other individuals who
will attend such meeting. All negotiations  pursuant to this Section 12(b) shall

Rule 408 of the Federal Rules of Evidence and similarly  under other federal and
state rules of evidence.

         (c) BINDING ARBITRATION. The Parties hereby agree to submit all
Disputes to arbitration under the following provisions, which arbitration shall
be final and binding upon the Parties, their successors and assigns, and that
the following provisions constitute a binding arbitration clause under
applicable law.

               (i) Either  Party may  initiate  arbitration  of a Dispute by 
delivery of a demand  therefor (the  "Arbitration  Demand") to the other Party 
not sooner than five (5) business  days after the date of delivery of the 
Dispute  Notice but at any time thereafter.

               (ii)The arbitration shall be conducted in the County of St.Louis,
Missouri,  by three arbitrators  (acting by majority vote, the "Panel") selected
by agreement  of the Parties not later than ten (10) days after  delivery of the
Arbitration  Demand  or,  failing  such  agreement,  appointed  pursuant  to the
Commercial Arbitration Rules of the American Arbitration Association, as amended
from time to time (the "AAA Rules").  If an arbitrator  becomes unable to serve,
his or her successor(s) shall be similarly selected or appointed.

               (iii)The arbitration shall be conducted pursuant to the Federal
Arbitration Act and the Missouri Uniform Arbitration Act, such procedures as the
Parties may agree or, in the absence of or failing such  agreement,  pursuant to
the AAA Rules. Notwithstanding the foregoing: (w) each party shall be allowed to
conduct discovery through written requests for information,  document  requests,
requests for stipulations of fact, and depositions; (x) the nature and extent of
such discovery  shall be determined by the Panel,  taking into account the needs
of the  Parties  and  the  desirability  of  making  discovery  expeditious  and
cost-effective; (y) the Panel may issue orders to protect the confidentiality of
information to be disclosed in discovery;  and (z) the Panel's discovery rulings
may be enforced in any court of competent jurisdiction.

               (iv) All hearings shall be conducted on an expedited schedule,
and all proceedings shall be confidential. Either Party may at its expense make
a stenographic record thereof.

               (v) The Panel shall  complete  all hearings not later than 
twenty (20) days after selection or appointment,  and shall make a final award
not later than ten (10) days  thereafter.  The award  shall be in  writing  and
shall specify  the factual  and legal  bases of the award. The Panel may assess
all or part of the costs and expenses of the  arbitration, including the Panel's
fees and expenses and fees and expenses of experts and legal counsel  
("Arbitration  Costs") as it deems  fair and  reasonable and, in  circumstances
where a Dispute has been asserted or defended against on grounds that the Panel
deems manifestly unreasonable  or  the  non-prevailing   Party  has  rejected
participation in procedures  under  Section  12(b),  the Panel may assess all  
Arbitration Costs against the  non-prevailing  Party and may include in the 
award the  Executive's and the Company's  attorneys'  fees and expenses in 
connection  with any and all proceedings under this Section 12. Notwithstanding
the foregoing, in no event may the Panel award multiple, punitive or exemplary 
damages to either Party.

          (d) CONFIDENTIALITY-NOTICE.Each Party shall notify the other promptly,
and in any event prior to  disclosure  to any third  person,  if it receives any
request for access to confidential information or proceedings hereunder.

     The Company shall have no right of setoff or counterclaim in respect of any
claim,  debt or obligation  against any payment  provided for in this Agreement,
except to the extent provided in Section 4 hereof.

     14. NON-EXCLUSIVITY OF RIGHTS

     Nothing in this Agreement shall prevent or limit the Executive's continuing
or future  participation  in any  benefit,  bonus,  incentive  or other  plan or
program provided by the Company or any of its subsidiaries or successors and for
which the Executive may qualify,  nor shall anything herein limit or reduce such
rights as the Executive may have under any other  agreements with the Company or
any of its  subsidiaries  or  successors.  Amounts which are vested  benefits or
which the  Executive is otherwise  entitled to receive under any plan or program
of the Company or any of its  subsidiaries  shall be payable in accordance  with
such plan or program, except as expressly modified by this Agreement.

     15. NO GUARANTEED EMPLOYMENT

     The Executive and the Company  acknowledge  that this  Agreement  shall not
confer  upon the  Executive  any  right to  continued  employment  and shall not
interfere  with the right of the  Company to  terminate  the  employment  of the
Executive at will, for any reason, and at any time, subject to the rights of the
Executive under any other agreement with the Company.

     16. NO TRUST CREATED

     Nothing  contained in this  Agreement  and no action taken  pursuant to the
provisions of this Agreement shall create or be construed to create a trust fund
of any kind.  Any funds which may be set aside or provided for in this Agreement
shall continue for all purposes to be a part of the general funds of the Company
and no person other than the Company  shall by virtue of the  provisions of this
Agreement  have any  interest  in such  funds.  To the  extent  that any  person
acquires a right to receive payments from the Company under this Agreement, such
right shall be no greater than the right of any  unsecured  general  creditor of
the Company.

     17. INVALIDITY OF PROVISIONS

     In the event that any  provision  of this  Agreement is  adjudicated  to be
invalid or unenforceable under applicable law in any jurisdiction,  the validity
or enforceability of the remaining  provisions thereof shall be unaffected as to
such  jurisdiction  and such  adjudication  shall not  affect  the  validity  or
enforceability of such provision in any other  jurisdiction.  To the extent that
any provision of this Agreement is  adjudicated  to be invalid or  unenforceable
because it is overbroad,  that  provision  shall not be void but rather shall be
limited to the extent required by applicable law and enforced as so limited. The
parties  expressly  acknowledge  and agree that this Section 17 is reasonable in
view of the Parties' respective interests.

     18. NON-WAIVER OF RIGHTS

     The failure by the Company or the  Executive  to enforce at any time any of
the  provisions of this  Agreement or to require at any time  performance by the
other party of any of the provisions hereof shall in no way be construed to be a
waiver of such provisions or to affect either the validity of this Agreement, or
any part  hereof,  or the right of the Company or the  Executive  thereafter  to
enforce each and every provision in accordance with the terms of this Agreement.

     19. MISCELLANEOUS

     No  provisions  of this  Agreement  may be  amended,  modified,  waived  or
discharged unless such amendment, waiver, modification or discharge is agreed to
in  writing  signed  by  the  Executive  and  the  Company.   No  agreements  or
representations,  oral or  otherwise,  express or implied,  with  respect to the
subject  matter  hereof  have been made by either  party which are not set forth
expressly  in  this  Agreement.   Section  headings  contained  herein  are  for
convenience  of reference only and shall not affect the  interpretation  of this
Agreement.
