Item 1.01  Entering into a Material Definitive Agreement.

     On April 3, 2006,  the Company  entered  into a Separation  Agreement  with
     Leicle E. Chesser (the "Chesser  Separation  Agreement") in connection with
     his resignation as Executive Vice President and Chief Financial  Officer of
     the Company and his election to the newly  created  office of Vice Chairman
     of the Company through December 31, 2006 (the  "Termination  Date").  Under
     the terms of the Chesser Separation Agreement, Mr. Chesser will receive the
     benefits described below in consideration of his agreeing to remain as Vice
     Chairman of the Company  through  December  31, 2006 and his  agreement  to
     provide the Company  with a general  release and his  agreement to abide by
     certain confidentiality,  non-competition and non-solicitation obligations.
     The Chesser Separation Agreement is attached hereto as Exhibit 10.1, and is
     incorporated by reference herein.

     Pursuant to the Chesser Separation  Agreement,  it was agreed,  among other
     things,  that Mr.  Chesser  shall  continue  to receive  his base salary of
     $450,000 per annum through the  Termination  Date. In addition,  he will be
     entitled  to be  considered  for a senior  executive  incentive  bonus with
     respect to the 2006 fiscal year, which such bonus (if any) shall be payable
     entirely  in cash no later  than  March  15,  2007.  Mr.  Chesser  shall be
     entitled to continue  his  participation  in the  Company's  benefit  plans
     through the Termination Date, and for 18 months after the Termination Date,
     the Company shall pay the employer's share of his health insurance premiums
     as if his employment had not been terminated.

     The  Separation  Agreement  also  provides,  among other  things,  that Mr.
     Chesser may  exercise the 67,400  options (as  adjusted  for the  Company's
     2-for-1 stock split  effective  February 10, 2006, the "Split")  granted to
     him on January 3, 2005 at any time prior to  December  31,  2007,  provided
     that he may not exercise  more than 22,466 of such options prior to January
     3, 2007. In addition,  shares issuable in respect of 6,834 restricted stock
     units (as adjusted for the Split)  granted to Mr. Chesser on March 3, 2005,
     under the Company's  Executive Stock Bonus Plan, shall be delivered on July
     1, 2007,  rather than on  termination  of  employment as is provided in the
     plan.  Mr.  Chesser also  relinquished  his rights under the Company's Long
     Term Incentive Plan (the "LTIP"),  including his rights,  if any, to 15,284
     stock units granted to him under the LTIP (as adjusted for the Split),  but
     Mr. Chesser  received 5,095 restricted stock units under the Company's 2003
     Management  Incentive Plan,  evidenced by a Restricted Share Unit Agreement
     dated  April 3,  2006,  the form of which  is  attached  to the  Separation
     Agreement as Exhibit I. The Company  also agreed to pay the annual  premium
     for 2006 of $14,859.20 on Mr. Chesser's term life insurance policy.

     In addition to agreeing to abide by  confidentiality,  non-competition  and
     non-solicitation  provisions,  Mr.  Chesser  agreed that for a period of 18
     months  from the  Termination  Date,  he would make  himself  available  to
     provide  consulting  services to the Company upon the Company's  request at
     the rate of $300 per hour. In addition, he agreed to make himself available
     to assist the  Company in any  investigations,  litigation  or other  court
     proceedings at the rate of $300 per hour.

Item 5.02 Departure of Directors or Principal  Officers;  Election of Directors;
     Appointment of Principal Officers.

     On April 3, 2006,  Mr.  Chesser  resigned as Executive  Vice  President and
     Chief  Financial  Officer of the Company and was elected to the position of
     Vice Chairman of the Company. In addition, on April 3, 2006, Mark A. Pompa,
     the Company's Senior Vice President-Chief  Accounting Officer and Treasurer
     was elected to the position of Executive Vice President and Chief Financial
     Officer of the  Company.  He will  retain the  office of  Treasurer  of the
     Company.

     In connection  with Mr.  Chesser's  resignation as the Company's  Executive
     Vice President and Chief  Financial  Officer,  the Company entered into the
     Chesser  Separation  Agreement  discussed  above in Item 1.01 and  attached
     hereto as Exhibit  10.1 to this  Current  Report on Form 8-K.  The terms of
     such Chesser Separation Agreement are incorporated herein by reference.

     On  April  3,  2006,  the  Company  issued a press  release  regarding  Mr.
     Chesser's  election as Vice Chairman,  and the election of Mark A. Pompa as
     Executive Vice President and Chief Financial Officer of the Company. A copy
     of such Press  Release is filed as Exhibit 99.1 to this  Current  Report on
     Form 8-K and is incorporated herein by reference.

Re:      Separation Agreement and Mutual Release

Dear Leicle:

     The  purpose of this  letter  agreement  and mutual  general  release  (the
"Agreement")  is to set forth the terms of our mutual  agreement  with regard to
your employment and separation from EMCOR Group, Inc. (the "Company").

1.   The Company has  informed  you that  effective  April 3, 2006 it intends to
     elect Mark A. Pompa,  Senior Vice President - Chief Accounting  Officer and
     Treasurer of the Company,  as its new Chief Financial Officer and has asked
     you to take on different responsibilities. Because of that proposed change,
     you have  informed  the Company  that you propose to resign.  However,  the
     Company has  requested,  and you have agreed,  that you shall remain in its
     employ as Vice Chairman of the Company with duties described in paragraph 2
     below through December 31, 2006 (the "Termination Date").

2.   From  April  3,  2006   through  the   Termination   Date  you  shall  have
     responsibility  with  respect to (a)  analysis  of  proposed  acquisitions,
     including  related due diligence,  (b) integration of acquisitions into the
     Company,  (c) review,  analysis and oversight of any proposed  expansion of
     the operations of the Company's Canadian subsidiary,  and (d) oversight and
     assistance in the  transition of Mark A. Pompa to Chief  Financial  Officer
     and the reorganization of his staff.

3.   Your  employment  shall  continue  through the  Termination  Date at a base
     salary of $450,000 per annum, which base salary shall be paid in accordance
     with the Company's  regular payroll  practices.  In addition,  you shall be
     entitled  to be  considered  for a senior  executive  incentive  bonus with
     respect to the Company's 2006  operations  and your personal  contributions
     thereto.  Such bonus,  if any,  shall be payable  entirely in cash no later
     than March 15, 2007.

4.   You shall be entitled, through the Termination Date, to the employee fringe
     benefits  that  you and  other  senior  executive  offices  of the  Company
     currently  enjoy.  Following the  Termination  Date and  continuing  for 18
     months  thereafter,  the  Company  shall  pay,  in  respect  of the  health
     insurance  premiums  for  your  COBRA  election,  an  amount  equal  to the
     employer's share of such premiums as if your employment had not terminated.
     In the event of your death,  the Company shall continue to pay such portion
     of the premiums  for your family  throughout  the period  noted  above.  In
     addition,  the Company  shall  reimburse  you for any valid and  reasonable
     outstanding  expenses  incurred  on its  behalf  during  the course of your
     employment   with  the   Company   after  you  submit   vouchers  or  other
     documentation  consistent with the Company's regular reimbursement policies
     and past practices.

               employment  will be treated as a termination  for good reason for
               purposes of determining your stock option entitlements; that such
               stock  options will be fully vested as of the  Termination  Date;

          (c)  If you receive a subpoena  from any person or entity  (including,
               but not limited to, any government  agency) to give testimony (in
               a deposition,  court  proceeding  or otherwise)  which in any way
               relates to the  Company  (including  its  subsidiaries  and other
               affiliates) or to your employment with the Company (including its
               subsidiaries  and  other  affiliates),  you  agree  that you will
               promptly  notify  the  General  Counsel  of  the  Company  of the
               subpoena and will make no disclosure  until the Company has had a
               reasonable opportunity (i) to contest the right of the requesting
               person  or  entity  to  such  disclosure  and/or  (ii) to seek to
               participate in the proceeding or matter in which the testimony is
               to be given,  except if the Company fails to timely  respond then
               you shall be entitled to comply with the  subpoena as required by
               law.

10.

          (a)  On the  Termination  Date,  you shall be deemed to have  resigned
               from all offices and directorships  then held with the Company or
               any subsidiary or affiliate thereof.

          (b)  You and  the  Company  shall  not  (except  as  required  by law)
               directly  or  indirectly   make  any  statement  or  release  any
               information, or encourage others to make any statement or release
               any  information  that is designed to embarrass or criticize  the
               other (or the Company's employees, directors or shareholders).

          (c)  During the period of your  employment  by the Company and for one
               year following the Termination Date, you agree that,  without the
               prior  written  consent of the  Company,  such  consent not to be
               unreasonably  withheld, you shall not, in any state in the United
               States  where a member of the  Restricted  Group (as that term is
               hereafter  defined)  conducts  business,  directly or indirectly,
               own,  manage,  operate,  conduct,  control or  participate  as an
               officer,  employee,  consultant,  partner,  or  equity  owner  or
               otherwise, in the ownership,  management,  operation,  conduct or
               control,  or accept employment with, or be connected in any other
               manner with, any business (a  "Business")  that is in competition
               with any member of the Restricted Group,  except for ownership of
               no more than 2% of the debt or equity  securities of corporations
               listed on a registered  securities exchange;  provided,  however,
               that a Business shall not be deemed to be in competition with any
               members  of the  Restricted  Group if (i) no more than 20% of the
               annual  consolidated  revenues of such  Business  (based upon its
               most recently  completed  fiscal year) are attributable to one or
               more business activities ("Incidental Competitive Activity") that
               are in competition  with any member of the  Restricted  Group and
               (ii)  you  are  not  engaged,  directly  or  indirectly,  in such
               Incidental  Competitive  Activity  and have no direct or indirect
               responsibility for, or oversight of, such Incidental  Competitive
               Activity.   "Restricted   Group"   means  the   Company  and  its
               subsidiaries  and  affiliates.   However,   notwithstanding   the
               foregoing,  you may act as a bona fide  outside  consultant  to a
               Business if such  consulting  services  are on an  assignment  by
               assignment  basis  and do not,  with  respect  to any  particular
               Business, represent regular, as opposed to occasional, consulting
               with such Business and any such assignment does not take any more
               than 90 days.

          (d)  For one year following the  Termination  Date, you agree that you
               shall not (without  the prior  written  consent of the  Company),
               either on your own  behalf or on  behalf of any  person,  firm or
               company,  directly  or  indirectly,  (a)  solicit,  encourage  or
               participate in soliciting or encouraging any customer or supplier
               of any member of the  Restricted  Group,  or any other  person or
               entity to terminate (or otherwise adversely alter) such person or
               entity's  customer,  supplier  or other  relationship  with  such
               member of the Restricted Group, and/or (b) hire any person who is
               at the time of the offer of  employment,  or within  three months
               prior  to such  offer  was,  an  employee  of any  member  of the
               Restricted  Group or encourage or  participate  in  soliciting or
               encouraging any employee of any member of the Restricted Group to
               terminate (or otherwise adversely alter) such person's employment
               relationship with such member of the Restricted Group.

          (e)  You and the Company  agree that the  covenants  set forth in this
               paragraph 10 are reasonable  covenants  under the  circumstances,
               and  further  agree that,  if in the  opinion of any  arbitration
               panel or court of competent  jurisdiction,  such restraint is not
               reasonable  in  any  respect,  this  Agreement  shall  be  deemed
               modified to the least  degree  necessary  to make this  Agreement
               reasonable  and fully  enforceable.  You agree that any breach of
               the covenants  contained in this  paragraph 10 would  irreparably
               injure the Company.  Accordingly, you agree that the Company may,
               in addition to pursuing any other  remedies it may have in law or
               in equity,  cease making any payments and/or  providing  benefits
               otherwise  required by this  Agreement,  including those provided
               for in  paragraphs  3 and 7  hereof,  and  obtain  an  injunction
               against you from any court  having  jurisdiction  over the matter
               restraining any further violation of this Agreement by you.

11.  You acknowledge  and agree that the payments,  benefits and/or other things
     of value provided to you and on your behalf  pursuant to this Agreement are
     in full discharge of any and all liabilities and obligations of the Company
     to you, monetarily or with respect to your employment.  You and the Company
     acknowledge  that nothing in this Agreement  shall impact your right to any
     vested  employee  benefits  that may have  accrued  under  the terms of the
     Company's benefit plans prior to your Termination Date.

12.

          (a)  For and in  consideration  of the  payments,  benefits  and other
               things  of value to be  provided  to you  and/or  on your  behalf
               pursuant  to this  Agreement,  you, on behalf of  yourself,  your
               heirs,  dependents,  executors,  administrators,  trustees, legal
               representatives   and  assigns   (collectively   referred  to  as
               "Releasors")  hereby  forever  release and discharge the Company,
               its  parents,  subsidiaries,   divisions,   affiliated  entities,
               branches,  predecessors,  successors  and  assigns  (collectively
               referred to herein as the "Company and/or its  affiliates"),  and
               all of its and their past  and/or  present  officers,  directors,
               agents,  attorneys,  representatives,  insurers,  employees,  and
               assigns,  whether  acting as agents for the Company,  or in their
               individual  capacities  (collectively with the Company and/or its
               affiliates  referred to as the "Company  Entities and  Persons"),
               from any and all  claims,  demands,  causes of action,  expenses,
               fees and  liabilities  of any kind  whatsoever,  whether known or
               unknown,  which  Releasors  ever had, now have,  or hereafter may
               have against any of the Company Entities and Persons by reason of
               employment,  breach of  agreement,  any  actual or  alleged  act,
               omission, transaction,  practice, conduct, statement, occurrence,
               or any  other  matter up to and  including  the date on which you
               sign this  Agreement,  except that this release  shall not affect
               any  claim  by  you  for   indemnification   by  the  Company  or
               contribution  from the Company or anyone else  relating to claims
               brought by parties  other than the  Company or in the name of the
               Company.

          (b)  Without  limiting  the  generality  of the  foregoing,  Releasors
               release and discharge the Company  Entities and Persons from: (i)
               any  claim  under  federal,  state or  local  law  pertaining  to
               employment   or   employment    discrimination    (statutory   or
               decisional),  including the Age Discrimination in Employment Act,

               (ii) any claim under the Employee  Retirement Income Security Act
               ("ERISA"); (iii) any claim under the Family and Medical Leave Act
               ("FMLA");  (iv) any claim  for  breach of  contract  (express  or
               implied) or tort, including claims of fraud, duress,  wrongful or
               constructive     discharge,      intentional     or     negligent

               or  compensatory  or  punitive  damages;  (vii) any  other  claim
               (whether  based on  federal,  state or local  law,  statutory  or
               decisional)  in connection  with,  relating to, or arising out of
               your  employment  with the Company  and/or its  affiliates or the
               terms  and  conditions  of  such  employment,  including  but not
               limited to, the  separation  or  termination  of such  employment
               and/or any of the events relating  directly or indirectly to such
               separation or  termination;  and (viii) any claim for  attorneys'
               fees,  costs,  disbursements and the like (which relate to claims
               referred  to in clauses (i)  through  (vii) of this  subparagraph
               12(b)), which Releasors ever had, now have, or hereafter may have
               against any of the Company  Entities and Persons by reason of any
               actual or alleged act, omission, transaction,  practice, conduct,
               statement,  occurrence,  or  other  matter  occurring  up to  and
               including the date on which you sign this Agreement.

          (c)  The provisions of paragraphs 12(a) and (b) above notwithstanding,
               nothing in this Agreement  shall  release,  diminish or otherwise
               affect any vested  monies or other  benefits  to which you may be
               entitled to under any pension or retirement savings plan.

          (d)  You   agree   not   to   commence   any   proceeding   (judicial,
               administrative  or  otherwise)  against the  Company  Entities or
               persons  with  respect  to any  matter  or claim  released  under
               paragraphs  12(a) and (b) above,  and you represent that you have
               not done so as of the date you sign this  Agreement.  You further
               agree  that  your  release  set  forth in this  Agreement  may be
               pleaded as a full and  complete  defense to any claim so released
               that is or may be  instituted,  prosecuted  or  maintained by any
               person or entity.

          (e)  The Company  represents  that,  as of the date hereof,  it is not
               aware of any  misconduct  or  neglect  on your  part  that  would
               subject you to liability  for your  conduct at the  Company,  and
               recognizes that you are relying on this representation in signing
               this   Agreement.   To  the   extent   you   are   eligible   for
               indemnification by the Company as an officer of the Company under
               the Company's  bylaws and certificate of  incorporation  or under
               applicable law or otherwise,  this Agreement shall have no impact
               on your eligibility for such indemnification.

          (f)  You  agree,  and  it  shall  be  a  condition  to  the  Company's
               obligations to provide you with the payments, benefits, and other
               things of value hereunder,  that you shall execute and deliver to
               the  Company  immediately  following  your  Termination  Date  an
               executed  form of  release  attached  hereto as  Appendix A which
               release  is not  thereafter  revoked.  If you  fail to do so this
               Agreement shall be null and void.

          (g)  Each of us acknowledges, for himself/itself, he/it is agreeing to
               the  releases  contained  in this  Agreement,  and is  releasing,
               waiving and  discharging  rights or claims,  only in exchange for
               consideration that he/it is not already entitled to receive.

13.

          (a)  For and in  consideration  of the value  provided  to the Company
               pursuant to this Agreement,  the Company,  its subsidiaries,  and
               their successors and assigns hereby forever release and discharge
               you from any and all claims, demands, causes of action, expenses,
               fees and  liabilities  of any kind  whatsoever,  whether known or
               unknown,  which the Company ever had,  now has, or hereafter  may
               have  against you by reason of  employment,  breach of  contract,
               breach of fiduciary  duty,  any actual or alleged act,  omission,
               transaction,  practice, conduct, statement,  occurrence, or other
               matter  up to and  including  the  date  hereof,  other  than any
               claims, demands, causes of action, expenses, fees and liabilities
               that arise out of (or otherwise relate to) willful misconduct, or
               gross neglect, by you.

          (b)  The Company  agrees not to  commence  any  proceeding  (judicial,
               administrative  or  otherwise)  against you,  with respect to any
               matter or claim released  under  paragraph  13(a) above,  and the
               Company represents that it has not done so as of the date hereof.
               The Company  further  agrees that its release may be pleaded as a
               full and complete defense to any claim so released that is or may
               be instituted, prosecuted or maintained by any person or entity.

          (c)  You  represent  that,  as of the  date on  which  you  sign  this
               Agreement,  you are not aware of any misconduct or neglect on the
               Company's part that would subject it to liability to you for your
               conduct,  and  recognizes  that the  Company is  relaying on this
               representation in signing this Agreement.

14.  Each of us agrees to perform  any  further  acts and to execute and deliver
     any further  documents  that may be  reasonably  necessary to carry out the
     provisions of this Agreement.

15.  If any  provision  of this  Agreement  shall be  declared  to be invalid or
     unenforceable,  in whole or in part,  such  invalidity or  unenforceability
     shall not affect the  remaining  provisions  hereof,  which shall remain in
     full force and effect.  Any controversy or claim arising out of or relating
     to this  Agreement or the breach of this  Agreement that cannot be resolved
     by you and the Company, including any dispute as to the calculation of your
     benefits or any payments  hereunder,  shall be submitted to  arbitration in
     New York, New York in accordance with the laws of the State of New York and
     the procedures of the American Arbitration Association, except if equitable
     relief is sought,  such  action  may be  brought in any court of  competent
     jurisdiction.  Judgment  may be entered on an  arbitrator(s)'  award in any
     court having jurisdiction.

16.  This Agreement shall be binding upon and inure to the benefit of your heirs
     and  representatives  and the assigns and  successors  of the Company,  but
     neither this  Agreement  nor any rights  hereunder  shall be  assignable or
     otherwise  subject to  hypothecation by you (except by will or by operation
     of the laws of intestate  succession) or by the Company (any such purported
     assignment  by either shall be null and void),  except that the Company may
     assign this  Agreement  to any  successor  (whether by merger,  purchase or
     otherwise) to all or substantially all of the stock,  assets or business of
     the Company.

17.  The  Agreement may be amended at any time,  but only by our mutual  written
     agreement. Either you or the Company may waive compliance by the other with
     any provision hereof,  but only by an instrument in writing executed by the
     one granting such waiver.

18.  All notices or communications  hereunder shall be in writing,  addressed as
     follows:

                                   Exhibit I
                                   ---------

                                EMCOR GROUP, INC.

                         RESTRICTED SHARE UNIT AGREEMENT



Recipient:    Leicle E. Chesser                   Date of Grant:  April 3, 2006
Number of RSUs:   5,095
Date of Vesting of RSUs:
The first business day immediately following
the day upon which the Company releases to
the public generally its results for the
fourth quarter of 2008


1.   Grant of RSUs.
     For valuable consideration,  receipt of which is hereby acknowledged, Emcor
     Group,  Inc., a Delaware  Corporation  (the  "Company"),  hereby grants the
     number of restricted stock units ("RSUs") listed above to the Recipient, on
     the terms and conditions hereinafter set forth. This grant is made pursuant
     to  the  terms  and  conditions  of the  Company's  2003  Management  Stock
     Incentive Plan (the "Plan").  Each RSU  represents the unfunded,  unsecured
     right of the  Recipient  to receive a share of common stock of the Company,
     $.01 par value per share (a "Share") on the date specified herein.

2.   Vesting and Timing of Transfer.

     (a)  The Recipient  will become  vested in the RSUs in accordance  with the
          schedule set forth above.

     (b)  The Company  shall  transfer to the  Recipient,  after the  applicable
          vesting  date,  a number  of Shares  equal to the  number of RSUs that
          became vested on that vesting date (rounded down, if necessary, to the
          next whole share).

     (c)  Notwithstanding  Sections  2(a) and 2(b) of this  Agreement,  upon the
          death of the  Recipient  or if there is a "Change of  Control"  of the
          Company,  as defined in the Plan,  the Company shall cause there to be
          transferred  to the Recipient,  as soon as  practicable  following his
          death or  Change  of  Control,  as the case may be, a number of Shares
          equal to the  aggregate  number of then  unvested  RSUs granted to the
          Recipient  under  this  Agreement.  In the  event of the  death of the
          Recipient,  the  transfer of Shares  under this  Section 2(c) shall be
          made in accordance  with a beneficiary  designation  form on file with
          the  Company;  provided,  however,  that,  in the  absence of any such
          beneficiary  designation  form,  the  transfer  of Shares  under  this
          Section  2(c)  shall  be made to the  person  or  persons  to whom the
          Recipient's  rights under the  Agreement  shall pass by will or by the
          applicable laws of descent and distribution.

     (d)  Upon each transfer of Shares in accordance  with Sections  2(a),  2(b)
          and 2(c) of this  Agreement,  a number of RSUs  equal to the number of
          Shares transferred to the Recipient shall be extinguished.

3.   Dividends.
     If on any date while RSUs are  outstanding  hereunder the Company shall pay
     any dividend on the Shares (other than a dividend  referred to in Section 4
     hereof),  the number of RSUs  granted to the  Recipient  shall,  as of such
     dividend  payment  date,  be increased by a number of RSUs (rounded down to
     the nearest whole RSU) equal to: (a) the cash value of the dividend paid on
     one  Share  multiplied  by the  number  of RSUs  represented  hereby on the
     dividend record date divided by (b) the closing price of a Share on the New
     York Stock Exchange on the trading day  immediately  preceding the dividend
     payment date.

4.   Adjustments   Upon   Certain   Events.
     In the event of any merger, reorganization, recapitalization, sale or other
     distribution  of assets of the  Company,  any stock or  extraordinary  cash
     dividend,  stock split,  spin-off,  split-up,  split-off,  distribution  of
     security or other property of the Company, or other change in the Company's
     capital  structure   affecting   Shares,   the  number  of  RSUs  shall  be
     appropriately  adjusted as  determined  by the  Compensation  and Personnel
     Committee of the Board of  Directors of the Company in its sole  discretion
     in a manner intended to prevent  dilution or enlargement of the benefits of
     the Recipient hereunder.

5.   No Rights of a  Shareholder.
     The Recipient  shall not have any rights or privileges as a shareholder  of
     the  Company  until the  Shares in  question  have been  registered  in the
     Company's register of shareholders.

6.   Transferability.
     Except as  provided  in  Section  2(c)  hereof,  RSUs may not be  assigned,
     alienated,  pledged,  attached, sold or otherwise transferred or encumbered
     by the  Recipient  otherwise  than by will or by the  laws of  descent  and
     distribution, and any purported assignment, alienation, pledge, attachment,
     sale, transfer or encumbrance not permitted by this Section 6 shall be void
     and unenforceable against the Company or any affiliate of the Company.

7.   Withholding.
     The  Recipient  may be required to pay to the Company and the Company shall
     have the right and is hereby  authorized  to withhold from any transfer due
     under this Agreement or from any  compensation or other amount owing to the
     Recipient,  applicable  withholding  taxes,  if any,  with  respect  to any
     transfer  under this  Agreement and to take such action as may be necessary
     in the opinion of the Company to satisfy all obligations for the payment of
     such taxes.

8.   Choice of Law.
     THE INTERPRETATION,  PERFORMANCE AND ENFORCEMENT OF THIS AGREEMENT SHALL BE
     GOVERNED BY THE LAWS OF THE STATE OF DELAWARE  WITHOUT REGARD TO PRINCIPLES
     OF CONFLICTS OF LAW.


9.   Signature in  Counterparts.
     This  Agreement  may be signed in  counterparts,  each of which shall be an
     original, with the same effect as if the signatures thereto and hereto were
     upon the same instrument.

            IN WITNESS WHEREOF, the parties hereto have executed this Agreement.
