                                RELEASE AGREEMENT

     THIS SEPARATION AND RELEASE  AGREEMENT  ("Agreement") is entered into as of
this 17th day of September, 2004, by and between Garry L. Randolph ("Employee"),
an individual  residing in the State of Missouri,  and Ameren  Services  Company
("Ameren"), a Missouri corporation, on behalf of itself and its subsidiaries and
affiliates.

                                    RECITALS
                                    --------

     A.  Employee  has been an employee  and officer of Ameren and an officer of
certain of Ameren's affiliated companies and entities.

     B.  Employee's  employment  with Ameren,  and all of its  subsidiaries  and
affiliated companies and entities,  will cease as of December 31, 2004, at which
time Employee shall retire.

     C.  Employee  and  Ameren  desire to end their  relationship  in a mutually
agreeable and satisfactory manner.

     D. Employee and Ameren desire to agree upon  provisions for the termination
of the employment  arrangement,  and provide for the  termination of all duties,
responsibilities, and compensation requirements of both parties.

     NOW,  THEREFORE,  for good and  valuable  consideration,  the  receipt  and
sufficiency  of  which is  hereby  acknowledged,  the  parties  hereto  agree as
follows:

     1.   Cessation of Duties as an Employee; Consulting Services.

          (a)  Employee will cease being  employed by  Ameren, and shall retire,
effective  at the close of  business  on  December  31,  2004 (the  "Termination
Date"), thereby terminating as of that date all further obligations of Ameren to
him,  of whatever  kind and  nature,  including  all forms of  compensation  and
benefits that otherwise  might have been due to the Employee  because of holding
any  employment or other  position with Ameren or its  affiliated  companies and
entities, except such compensation and benefits as are expressly provided for in
this Agreement.  As of the Termination Date, Employee resigns from his positions
as an officer of Ameren and all affiliated  companies and entities.  Through the
Termination  Date Employee shall perform such duties as shall be assigned to him
by Ameren,  and Paragraphs 2 and 3 of this Agreement  shall be effective only in
the event Employee performs such duties to the satisfaction of Ameren.

          (b) For the twelve-month  period beginning  January 1, 2005 and ending
December  31, 2005,  Employee  shall render  consulting  services to Ameren,  in
accordance with the terms of the Consulting Agreement attached hereto as Exhibit
B.

     2.   Restricted Stock.   Employee has been awarded  Restricted Shares under
the Ameren Corporation  Long-Term Incentive Plan of 1998 (the "Incentive Plan"),
as defined and set forth in those  Restricted  Stock Awards under the  Incentive
Plan and Notices of Restricted




Stock Award  previously  granted to Employee  (the  "Awards"),  and dividends on
Restricted  Shares have been  reinvested in additional  Restricted  Shares.  The
Restrictions, as defined in the Awards, shall lapse on the Employee's Restricted
Shares  in  accordance  with  and  to the  extent  provided  in  the  applicable
provisions  of the Awards as if the  Employee's  employment  with Ameren had not
terminated.  Except as otherwise  provided in this Paragraph 2, the  provisions,
terms and  conditions  of the  Incentive  Plan and the Awards shall  continue in
effect with respect to the Employee and his Restricted Shares.

     3.   Stock  Options.  In  accordance  with  their  terms,   the  Employee's
outstanding  options to purchase  shares of common  stock of Ameren  Corporation
which were granted  under the  Incentive  Plan or a  substantially  similar plan
previously  adopted  by Union  Electric  Company,  whether  otherwise  vested or
unvested on the Termination Date, may be exercised within thirty-six (36) months
after the  Termination  Date;  provided,  however,  that no such  option  may be
exercised  after the expiration  date set forth in the  applicable  stock option
agreement  therefor.  At the end of such  thirty-six  (36) month  period (or, if
earlier,  the expiration  for any such option),  any  unexercised  options shall
terminate and cease to be exercisable.

     4.   Retiree  Medical  Coverage.  From  and  after  the  Termination  Date,
Employee  and his  eligible  dependents  shall be  entitled  to retiree  medical
coverage under the Ameren Group Medical Plan (the "Medical Plan"), in accordance
with the  provisions,  terms and  conditions  thereof,  subject  to the right of
Ameren Corporation to amend or terminate the Medical Plan at any time.

     5.   Salary, Vacation Pay and Annual Bonus.

          (a) On the  Termination  Date,  Employee shall be paid any accrued but
unpaid salary and vacation pay, subject to applicable  federal,  state and local
withholding taxes.

          (b)  Employee  shall receive an annual bonus under the 2004  Executive
Incentive Plan, determined and payable as provided in Exhibit A hereto,  subject
to applicable federal, state and local withholding taxes.

     6.   Benefit  Plans.  Employee  acknowledges  that  except as  provided  in
Paragraphs 2, 3, 4 and 5 of this Agreement and Exhibit A hereto, Employee is not
entitled to any payments or benefits under any employee benefit plan (as defined
in this Paragraph 6) of Ameren or its affiliates, including, without limitation,
the Ameren  Corporation  Change in Control  Plan and the Ameren  Severance  Plan
(collectively, the "Plans").

     With  respect to Plan  amounts  set forth on Exhibit  A,  unless  otherwise
explicitly  stated,  such  amounts  have  been  determined  consistent  with the
respective  Plan  provisions and  consistent  with Ameren's  normal  practice in
determining such benefit amounts.  If Ameren becomes aware of any discrepancy in
any  amount  set forth in  Exhibit A, it will  immediately  notify  Employee  in
writing of such discrepancy and make an appropriate adjustment, whether positive
or negative, to the respective Plan account balance.

     "Employee benefit plan" means each deferred compensation and each incentive
compensation,  stock purchase,  stock option and other equity compensation plan,
program,  agreement or arrangement;  each severance or termination pay, medical,
surgical,  hospitalization,

                                       2




life insurance and other  "welfare" plan, fund or program (within the meaning of
Section 3(1) of Title I of the Employee  Retirement  Income Security Act of 1974
("ERISA");  each  profit-sharing,  stock bonus or other  "pension" plan, fund or
program  (within  the  meaning  of  Section  3(2)  of  Title I of  ERISA);  each
employment,  termination or severance agreement; and each other employee benefit
plan, fund, program, agreement or arrangement,  in each case, that is sponsored,
maintained or  contributed  to or required to be  contributed to by Ameren or by
any of its  affiliates,  or to which Ameren or any of its  affiliates  is party,
whether written or oral, for the benefit of the Employee.

     7.   General and Full Release. Effective upon the date of execution of this
Agreement, subject to the revocation period provided for below in this Paragraph
7, (a) the Employee expressly waives any claim, demand or right to reinstatement
or rehiring to any position or relationship with Ameren, or any other subsidiary
or affiliate of Ameren, now and in the future, and (b) on behalf of himself, his
heirs and assigns and for the consideration provided for in this Agreement,  the
Employee hereby releases,  settles, and forever discharges Ameren, its officers,
directors, shareholders,  employees, agents, representatives and successors, and
each  of its  subsidiaries  and  affiliates  and  the  officers  and  directors,
shareholders,  agents  and  representatives  of each,  and any  related  entity,
including  the Plans and each  administrator,  trustee and  fiduciary  under the
Plans  (collectively  referred to as the  "Releasees")  from any and all claims,
complaints, actions, rights, demands, damages, or any liability of whatever kind
or nature (including attorneys' fees and costs actually incurred), whether known
or unknown, including, but without limiting the generality of the foregoing, (i)
except as provided in Paragraph 6 and in Exhibit A, any claim  arising under the
Plans, (ii) any claim pursuant to or under the Age  Discrimination in Employment
Act, Title VII of the Civil Rights Act of 1964, the Americans with  Disabilities
Act, the  Rehabilitation  Act of 1973, the Equal Pay Act, the Family and Medical
Leave Act,  the Employee  Retirement  Income  Security  Act  (ERISA),  42 U.S.C.
ss.ss.1981,  et seq., the Missouri  Human Rights Act (R.S.Mo.,  Chapter 213, et.
seq.), the Missouri Service Letter Statute (R.S.Mo.  ss.290.140), or pursuant to
any employment  discrimination laws of any federal,  state, or local government,
(iii) any claim based upon contract,  direct or implied, or upon a tort claim of
any kind,  relating to or arising from  employment  with  Ameren,  or any of its
subsidiaries  or  affiliated  entities,  or  (iv)  any  claim  relating  to  the
resignation  or  termination  of the Employee  from  employment  by and from any
position  with Ameren or any  subsidiary  or  affiliated  entity of Ameren.  The
Employee  further  understands  that the payments  and benefits  provided to the
Employee  in this  Agreement  constitute  full  consideration  for the  complete
release and  discharge by the Employee of all claims and actions  against any of
the  Releasees  that can be lawfully  released and waived,  of whatever  kind or
nature,  whether arising or pursuant to a federal,  state or local law, statute,
ordinance or  regulation,  or otherwise  arising by contract,  by law, or in any
manner.

     Employee  expressly  agrees,  acknowledges  and  understands  that: (A) the
consideration  set  forth  in  Paragraphs  2 and 3 and,  in  part,  5(b) of this
Agreement is consideration  that he is not otherwise entitled to and is given in
exchange  for the  release  contained  in  this  Paragraph  7 and for the  other
promises  contained in this  Agreement;  (B) he is waiving any and all rights or
claims arising under the Age  Discrimination in Employment Act; (C) he has been,
and is hereby,  advised by Ameren to consult with an attorney prior to executing
the Agreement;  (D) he has been given a period of at least  twenty-one (21) days
within  which to  consider  the  Agreement;  (E) the  Agreement  does not become
effective or enforceable until seven (7) days after he executes it


                                       3




or, if later,  seven (7) days  after the end of the  twenty-one  (21) day period
described  in clause (D);  (F) he may revoke the  Agreement at any time prior to
the end of the applicable  seven (7) day period described in clause (E); and (G)
he shall not be entitled to any payments or benefits  under this Agreement if he
revokes it in accordance with clause (F).

     Notwithstanding  the release given by Employee in this paragraph 7, nothing
in this Agreement shall be deemed to limit:

          (a) Any right of  indemnification to which Employee might otherwise be
entitled pursuant to the Articles of Incorporation of Ameren; and

          (b)  Any fiduciary insurance, director and officer liability insurance
coverage, and any other liability insurance coverage provided by Ameren.

     Ameren,  for itself and all of its  subsidiaries  and  affiliated  entities
(collectively  referred  to as  "Releasors"),  does hereby  remise,  release and
forever  discharge  Employee  and all of his  personal  representatives,  heirs,
devisees,  agents and assigns (collectively referred to as "Employee Releasees")
of and from any and all claims,  complaints,  actions, rights, demands, damages,
claims for  indemnity or  contribution,  or any  liability  of whatever  kind or
nature (including attorneys' fees and costs actually incurred), whether known or
unknown,  including,  but without  limiting  the  generality  of the  foregoing,
anything relating to or arising from Employee's  employment by Ameren and/or its
subsidiaries or affiliates for the benefit of one or more of them, or Employee's
actions  as an  employee,  officer,  director  or  shareholder  of  Ameren,  its
subsidiaries or affiliates, arising prior to the Effective Date.

     In  agreeing  to the  respective  release  of  claims  set  forth  in  this
paragraph, Employee does not waive any rights or claims that may arise after the
date this  Agreement  is executed and Ameren does not waive any rights or claims
that may arise on or after the date this Agreement is executed.

     8.   Confidentiality.  Employee  agrees  not to  disclose  or use  for  his
account or for the benefit of any third party,  now or in the future,  any trade
secrets, marketing, financial, management,  personnel, hiring, salary, know-how,
ideas, or any other information  concerning Ameren or any of its subsidiaries or
related entities  (collectively,  the "Confidential  Information"),  whether the
Employee  has such  information  in his memory or  embodied  in writing or other
physical form. Further, Employee agrees not to divulge or release this Agreement
or its contents, except to his attorney, financial advisor, or immediate family,
provided they agree to keep this document and its contents confidential, and not
disclose it to anyone  except  pursuant to a valid court  subpoena.  Information
that is or  becomes  publicly  available  through no  wrongful  act or breach of
obligation by Employee shall not be deemed to be  Confidential  Information.  In
the event the Employee  receives a court subpoena  requiring the release of this
Agreement or its content or any  Confidential  Information,  the  Employee  will
notify  Ameren  sufficiently  in advance of the date for the  disclosure of such
information  in order to enable  Ameren to contest  the  subpoena  and  Employee
agrees to cooperate with Ameren in any court proceeding involving the release of
Confidential Information pursuant to such subpoena.

                                       4




     9.   Non-Disparagement.    Employee agrees that he will not make any public
statement  which  would  adversely  affect the  business  of Ameren or any other
related entity of Ameren, in any manner, at any time, even beyond the date after
which  Employee  will  receive no further  compensation  or benefits of any kind
pursuant to the provisions of this  Agreement.  The Employee agrees that he will
not  publicly  disparage,  criticize  or speak  negatively  about  Ameren or its
subsidiaries  and  affiliates,  or  their  decisions  or  actions,  about  their
products,  services or  operations,  about any of their past,  present or future
directors,  officers or employees or any of their actions or decisions, or about
its customers.  Ameren and any of its  subsidiaries and affiliates will not, and
shall take all necessary or  appropriate  action to ensure that the officers and
directors  of  Ameren  and any of its  subsidiaries  and  affiliates  will  not,
disparage,  criticize or speak negatively  about the Employee,  his work, or the
decisions he made while employed by Ameren or any of its related  entities.  The
parties  agree  that  the  Employee  shall  refer  any  and all  inquiries  from
prospective employers solely to Donna K. Martin.

     10.  Non-Solicitation.    Employee will not, directly or indirectly, either
for his own account or for the account of any other entity or person, (i) induce
or attempt to induce any employee of Ameren or an affiliated entity to leave the
employ of such entity,  (ii) in any way interfere with the relationship  between
Ameren and its  affiliates  and any  employee of such  entity,  (iii)  employ or
otherwise  engage as an  employee,  independent  contractor,  or  otherwise  any
employee of Ameren or an affiliated  entity, or (iv) induce or attempt to induce
any  customer,  supplier,  licensee,  or  business  relation  of  Ameren  or  an
affiliated  entity  to  cease  doing  business  with the  entity,  or in any way
interfere with the relationship  between any customer,  supplier,  licensee,  or
business relation of Ameren or an affiliated entity.

     11.  Remedies.    The Employee and Ameren respectively acknowledge that the
other party would be greatly injured by, and have no adequate remedy at law for,
breach of his or its obligations under Paragraphs 8, 9 and 10 of this Agreement.
Accordingly,  each of the parties  agrees that wherever such breach occurs or is
threatened,  the other party may, in addition to all other remedies available to
it, enjoin the party committing such breach or threatened  breach (together with
all persons  acting with such party from such breach or threatened  breach).  In
each case,  the losing party shall pay the court costs,  attorney fees and other
expenses of the prevailing party in enforcing its rights under this Agreement.

     12.  Governing Law and Third Party Benefit.  Employee and Ameren agree that
this  Agreement  shall be governed by, and  interpreted  in accordance  with the
internal  laws,  and not the  conflicts of laws,  of the State of Missouri.  The
provisions  of this  Agreement are intended to benefit each of the Releasees and
Employee  Releasees and as such may be enforced by each Releasee in such party's
individual right.

     13.  Severability.  In the event that a provision of this  Agreement,  or a
portion thereof, is judicially  determined to be unenforceable as written,  such
provision shall be construed so as to give it the maximum effect permitted under
applicable  law, or, in the event such  provision  would  otherwise  render this
Agreement void or  unenforceable,  such provision  shall be considered  stricken
from the Agreement and as if it had never been included herein.

     14.  Entire  Agreement. This  Agreement  constitutes  the entire  agreement
between Ameren and Employee with respect to the subject matter of this Agreement
and supersedes all


                                       5




prior  negotiations and agreements,  whether written or oral. This Agreement may
not be altered or amended except by a written document  executed by the parties.
Employee represents and acknowledges that in executing this Agreement he has not
relied upon any  representation or statement not set forth herein made by Ameren
or any of the Releasees or by any of the Releasees' agents, representatives,  or
attorneys with regard to the subject matter,  basis or effect of this Agreement,
Ameren, its business or its stock, or any other matter.

     15.  Arbitration.  Other  than  disputes  pertaining  to the  Plans  or the
provisions of Paragraphs 8, 9, 10 and 11, any other dispute regarding any aspect
of this Agreement or any act which  allegedly has or would violate any provision
of  this  Agreement  ("Arbitrable  Claim")  will  be  exclusively  submitted  to
arbitration  before a neutral  arbitrator.  If Employee and Ameren are unable to
agree  upon a  neutral  arbitrator,  the  parties  will  obtain  a list  of five
arbitrators from the American Arbitration Association. Employee (first) and then
Ameren will alternately  strike names from the list until only one name remains;
the remaining person shall be the arbitrator.  Arbitration of Arbitrable  Claims
shall  be in  accordance  with the  Dispute  Resolution  Rules  of the  American
Arbitration Association for employment. Arbitration proceedings shall be held in
St. Louis,  Missouri or at any other location  mutually  agreed upon by Employee
and  Ameren.  The  arbitrator  shall  determine  the  prevailing  party  in  the
arbitration.  The arbitrator  shall be permitted to award only those remedies in
law or equity which are  requested by the parties,  appropriate  for the claims,
and  supported by credible,  relevant  evidence.  Employee and Ameren agree that
this arbitration  shall be the exclusive means of resolving any Arbitrable Claim
and that no other  action  will be  brought  by  Employee  in any court or other
forum.  Notwithstanding,  any  party  may  bring an  action  in court to  compel
arbitration under this Agreement and to enforce an arbitration award. Otherwise,
neither  Employee  nor  Ameren  shall  initiate  or  prosecute  any  lawsuit  or
administrative  action in any way related to any Arbitrable  Claim.  The Federal
Arbitration  Act  shall  govern  the  interpretation  and  enforcement  of  this
Paragraph 15.

     IN WITNESS WHEREOF,  the undersigned have executed this Agreement as of the
17th day of September, 2004.

     PLEASE READ  CAREFULLY.  THIS SEPARATION AND RELEASE  AGREEMENT  INCLUDES A
RELEASE OF ALL CLAIMS. THIS AGREEMENT CONTAINS A BINDING  ARBITRATION  PROVISION
WHICH MAY BE ENFORCED BY THE PARTIES.

                              CONSULTING AGREEMENT

     This  Consulting  Agreement  (the  "Agreement")  is made and  entered  into
effective as of the 17th day of September,  2004, by and between Ameren Services
Company,   a   Missouri   corporation   ("Company"),   and  Garry  L.   Randolph
("Consultant"), (as an individual or as a business entity as the case may be).

         A.    Company is engaged in the business of providing  energy  services
to customers in Missouri and Illinois, with its headquarters and principal place
of business located in St. Louis, Missouri.

         B.    Company desires  to engage Consultant, and  Consultant  wishes to
be engaged by Company, to perform consulting services, upon the terms herein set
forth.

         C.    Company  has expended  a great deal of time,  money and effort to
develop  and  maintain  its  proprietary  Confidential  Information  (as defined
herein)  which,  if misused or  disclosed,  could be very  harmful to  Company's
business.

          D.   The success of Company depends to  a substantial  extent upon the
protection of its Confidential Information and customer goodwill.

          E.  Following  Consultant's  engagement  by Company,  Company,  in all
fairness   needs   certain   protections   in  order  to   prevent   misuse   or
misappropriation by Consultant of the Confidential Information.

          NOW,  THEREFORE,  in  consideration  of the premises and of the mutual
covenants and agreements hereinafter set forth, it is agreed as follows:

     1.   Engagement.

          (a)  Subject to the terms and provisions of this Agreement and for the
term  hereinafter  set  forth,  Company  hereby  engages  Consultant  to perform
consulting services at times and locations  reasonably agreeable to both parties
for Company,  its  subsidiaries or affiliates on an as-needed basis as requested
by Company, but not in excess of 800 hours in 12-month period during the term of
this Agreement.  Consultant hereby accepts such engagement pursuant to the terms
and provisions herein.

          (b)  Consultant  warrants that his  consulting  services under Section
1(a) shall be performed in a good,  workmanlike  manner,  in conformity with the
highest  professional  and ethical  standards,  in an expeditious and economical
manner,  consistent  with the best interests of Company,  and in compliance with
all statutes, laws, ordinances, codes, rules and regulations applicable thereto.
Nothing in this  Agreement  shall in any manner  prevent or restrict  Consultant
from seeking other  consulting or  employment  opportunities,  either during the
term of this Agreement or after its expiration or termination.



                                                                       Exhibit B

     2.   Term and Termination.

          (a)  The term of this Agreement shall be for a period of twelve months
commencing  January 1, 2005 and ending  December  31,  2005,  unless  terminated
earlier in accordance with the provisions of Section 2(b).

          (b)  Company may terminate this Agreement  effective  immediately upon
written notice to Consultant if Consultant:

               (i) fails to  perform  his duties and  obligations  hereunder  as
described in section 1 (a) of this Agreement;

               (ii) breaches any of the terms or conditions hereof; or

               (iii)  commits  acts  constituting  willful  fraud or  dishonesty
against  Company or willful  conduct which  significantly  impairs the
reputation of, or harms, Company, its subsidiaries or affiliates.

     3.   Consulting Fees.

          (a)  In consideration for the consulting services described in Section
1 and subject to the due performance  thereof,  Consultant  shall receive during
the term of this  Agreement  the  amount of  $350,000,  to be paid by Company in
monthly installments on the first day of each month.

     4.   Independent  Contractor.   Consultant  is retained by Company only for
the  purposes  of,  and to the  extent  set forth in,  this  Agreement,  and the
relationship of Consultant with Company under this Agreement shall be that of an
independent  contractor.  Subject to the limitations and conditions set forth in
Section 1,  Consultant  agrees to devote  sufficient  time,  effort,  resources,
ability,  skill and attention as may be necessary for  Consultant to perform the
services required to be provided to Company under this Agreement, but Consultant
shall  have the full  authority  to select  the  means,  manner,  and  method of
performing  such services.  Consultant  shall not be considered by reason of the
provisions of this Agreement or otherwise as being an employee of Company. As an
independent  contractor,  Consultant  shall not be  entitled  to any  insurance,
retirement or other  benefits  afforded  generally by Company to its  employees.
Consultant  shall be responsible for all federal,  state and local taxes payable
in connection with the services he renders  pursuant to this Agreement.  Company
agrees to  reimburse  Consultant  for  reasonable  expenses  incurred in travel,
transportation and living expenses away from his permanent residence. Consultant
agrees to provide a listing of expenses  with copies of airline  tickets,  hotel
bills,  car rental  receipts,  copies of receipts  and/or  description  of other
expenses.

     5.   Confidential Information.

          (a) Both  during  and  after  the term of this  Agreement,  Consultant
agrees to keep secret and confidential,  and not to use or disclose (directly or
indirectly) to any third parties,  except as directly required for Consultant to
perform  Consultant's  responsibilities  to Company hereunder,  any of Company's
Confidential Information.


                                                                               2



                                                                       Exhibit B

services for which he is being engaged.  Consultant will not copy,  reproduce or
otherwise duplicate,  record, abstract,  summarize or otherwise use, any papers,

Property"),  which  are  developed,  conceived,  created,  discovered,  learned,
produced  and/or  otherwise  generated by Consultant,  whether  individually  or
otherwise, during the time that Consultant is engaged by Company, that relate to
(i) the  business  and/or  activities  of Company,  (ii)  Company's  anticipated
research or development,  or (iii) any work performed by Consultant for Company,
shall be the sole and exclusive  property of Company,  and Company shall own any
and all right, title and interest to such.  Consultant hereby assigns and agrees
to assign to Company  any and all right,  title and  interest in and to any such
Intellectual   Property,   and   Consultant   agrees  to  execute  any  and  all
applications,  assignments or other  instruments,  at Company's  expense,  which
Company  deems  necessary or  appropriate  to evidence such  assignments  and to
protect such interests.

          (b)  Section  6(a)  shall  not  apply to any  invention  for  which no
equipment,  supplies, facilities, or Confidential Information of Company is used
and which was  developed  entirely  on  Consultant's  own time,  unless  (i) the
invention  relates  to the  business  and/or  activities  of  Company,  (ii) the
invention  relates to Company's actual or demonstrably  anticipated  research or
development,  or  (iii)  the  invention  results  from  any  work  performed  by

documentation and other copyrightable  works.  Consultant hereby agrees that any
and all computer programs,  documentation and other copyrightable materials that
he has prepared or worked on for  Company,  or is asked to prepare or work on by
Company,  shall be  "works  made for hire"  and that  Company  shall own all the
copyright rights in such works. If and to the extent that such material does not
satisfy the legal  requirements  to constitute a work made for hire,  Consultant
hereby assigns all of his copyright rights in the work to Company.

     7.  Company  Property.  Consultant  acknowledges  that  any and all  notes,
records,  sketches,  computer diskettes,  training materials and other documents
relating to Company  obtained by or provided to Consultant,  or otherwise  made,
produced or compiled during the term of this Agreement regardless of the type of
medium in which  they are  preserved,  are the sole and  exclusive  property  of
Company and shall be surrendered to Company  immediately upon the termination of
Consultant's engagement hereunder and on demand at any time by Company.

                                                                               4



                                                                       Exhibit B

     8.  Company's  Right to  Injunctive  Relief.  In the  event of a breach  or
threatened breach of any of Consultant's  duties and obligations under the terms
and provisions of this Agreement,  Company shall be entitled, in addition to any
other legal or equitable remedies it may have in connection  herewith (including
any  right  to  damages  that it may  suffer),  to  temporary,  preliminary  and
permanent  injunctive  relief  restraining  such  breach or  threatened  breach.
Consultant  hereby  expressly  acknowledges  that the harm which might result to
Company's  business as a result of any  noncompliance  by Consultant with any of
the  provisions  of  Sections  5 or 6 would be largely  irreparable.  Consultant
specifically  agrees that if there is a question as to the enforceability of any
of the provisions of Sections 5 or 6 hereof,  Consultant  will not engage in any
conduct  inconsistent with or contrary to such sections until after the question
has been resolved by a final judgment of a court of competent jurisdiction.

     9.  Judicial   Enforcement.   If  any   provision  of  this   Agreement  is
unenforceable  under  applicable  law,  that shall not affect  the  validity  or
enforceability of the remaining provisions.  To the extent that any provision of
this Agreement is  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.

     10. Assignment. This Agreement shall be freely assignable by Company to its
subsidiaries  and shall  inure to the  benefit of and be binding  upon any other
entity which shall succeed to the business  presently being operated by Company.
Neither this Agreement nor any rights  hereunder shall be assigned by Consultant
because of the personal services nature of this Agreement.

     11.  Choice of Forum and Governing  Law. In light of Company's  substantial
contacts  with the State of Missouri,  the parties'  interests in ensuring  that
disputes  regarding  the  interpretation,  validity and  enforceability  of this
Agreement are resolved on a uniform basis,  and Company's  execution of, and the
making  of,  this  Agreement  in  Missouri,  the  parties  agree  that:  (i) any
litigation  involving  any  noncompliance  with or breach of the  Agreement,  or
regarding the interpretation,  validity and/or  enforceability of the Agreement,
shall be filed and conducted in the state or federal courts in St. Louis City or
County, Missouri; and (ii) the Agreement shall be interpreted in accordance with
and  governed  by the laws of the  State of  Missouri,  without  regard  for any
conflict of law principles.

     12.  Integration  and  Amendments.  This Agreement  constitutes  the entire
agreement  between the parties with  respect to the subject  matter  hereof.  No
modification,  amendment or waiver of any of the  provisions  of this  Agreement
shall be effective unless in writing  specifically  referring hereto, and signed
by the parties hereto.

     13.  Right to Recover  Costs.  Consultant  undertakes  and  agrees  that if
Consultant  breaches or  threatens to breach any  provision  of this  Agreement,
Consultant shall be liable for any attorneys' fees and costs incurred by Company
in enforcing its rights under this Agreement. Company undertakes and agrees that
if company  breaches or  threatens to breach any  provision  of this  Agreement,
Company shall be liable for any attorneys' fees and costs incurred by Consultant
in enforcing his rights under this Agreement.

     14.  Non Waiver of  Rights.  The  failure 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

                                                                               5


                                                                       Exhibit B

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 either party  thereafter  to enforce each and every  provision in  accordance
with the terms of this Agreement.

     15.  Survival.  The  provisions  of  Sections 5, 6, 8, 9, 11, 13, 14 and 16
hereof shall survive the termination of this Agreement.
