GUARANTEE

               In order to induce Dime Commercial  Corp.  (which,  together with
its successors,  endorsees and assigns,  is hereinafter  called the "Lender") to
make such advances,  loans or extensions of credit,  directly or indirectly,  to
GSE Power Systems,  Inc. ("Power") and GSE Process Solutions,  Inc.  ("Process")
(hereinafter,  whether one or more,  called the  "Borrower") and to grant to the
Borrower  such  renewals,  extensions,  forbearances,  releases of collateral or
other relinquishments of rights as the Lender may deem advisable,  and for other
valuable  consideration,  the  receipt  of which  is  hereby  acknowledged,  the
undersigned  (hereinafter,  whether one or more, called the "Guarantor") who, if
more  than  one,  shall  be  jointly  and  severally  liable  hereunder,  hereby
absolutely  and  unconditionally  guarantees  to the Lender the due and punctual
payment when due,  whether by acceleration or otherwise,  in accordance with the
terms  thereof,  of the  principal of and interest on and all other sums payable
with  respect to any and every  obligation  or  liability of the Borrower to the
Lender,   whether  now  existing  or  hereafter  incurred  (including,   without
limitation,  interest  accruing after, and advances made after, the commencement
of a  bankruptcy  case or  proceeding  with  respect to the  Borrower),  whether
contracted by the Borrower alone or jointly with others, and whether absolute or
contingent,  secured  or  unsecured,  matured or  unmatured  arising  under,  in
connection with or relating to the Loan and Security Agreement dated June , 1999
(as amended,  modified,  restated or  supplemented  from time to time, the "Loan
Agreement")  among GSE  Systems,  Inc.,  GSE Power  Systems,  Inc.,  GSE Process
Solutions,  Inc.,MSHI, Inc., GP International Engineering & Simulation, Inc. and
Lender (such  obligations  and  liabilities  of the Borrower  being  hereinafter
collectively called the  "Liabilities").  Notwithstanding any language contained
in this Guarantee relating to loans, it is expressly intended,  contemplated and
agreed that  Guarantor's  obligations  under this Guarantee shall extend to each
and all of the Liabilities,  whether or not such Liabilities  relate directly or
indirectly to loans.

               The liability of the Guarantor hereunder shall in no event exceed
the principal amount of One Million Eight Hundred Thousand Dollars  ($1,800,000)
(the  "Original  Principal  Amount") as such amount may be increased as provided
below in this paragraph,  plus interest on such amount to the extent hereinafter
provided  in  this  Guarantee  and  expenses  related  to  enforcement  of  this
Guarantee.  Interest  will  accrue on the  principal  amount of the  Guarantor's
obligations  hereunder  from and after  the date  three  (3)  Business  Days (as
defined in the Loan  Agreement)  after any demand for payment  hereunder  at the
Default Rate (as defined in the Loan Agreement).  The Original  Principal Amount
shall be increased by (a) the amount of all payments by the Guarantor  hereunder
of the outstanding principal amount of the Liabilities of Process, provided that
the amount of such increase shall not exceed  $1,500,000,  and (b) the amount of
all payments by the Guarantor  hereunder of the outstanding  principal amount of
the  Liabilities  of Power,  provided that the amount of such increase shall not
exceed $1,500,000.  In no event will the Guarantor be obligated to pay hereunder
more than $3,300,000 of the outstanding  principal  amount of the Liabilities of
Power and Process in the aggregate  (including the Original  Principal  Amount),
plus  interest  and  enforcement  expenses  as herein  provided.  The  Lender is
expressly  authorized  to demand  payment  from the  Guarantor  and enforce this
Guarantee  against the  Guarantor and to recover the Original  Principal  Amount
plus the  maximum  amount  by  which  the  Original  Principal  Amount  could be
increased pursuant to this paragraph.  Notwithstanding  anything to the contrary
herein,  in the event of the  occurrence  of any Event of Default under the Loan
Agreement,  the Lender shall have the right at any time to commence a litigation
against the Guarantor and exercise any other remedies and to recover a principal
amount equal to the  outstanding  principal  amount of the  Liabilities of Power
(other  than its  Liabilities  under  Section 11 of the Loan  Agreement)  not to
exceed  $1,800,000 plus the outstanding  principal  amount of the Liabilities of
Process (other than its Liabilities  under Section 11 of the Loan Agreement) not
to exceed  $1,500,000,  plus such interest and enforcement  expenses referred to
above.  In any such  litigation,  the Guarantor shall not be permitted to assert
that its liability hereunder is limited to $1,800,000. Moreover, in the event of
any bankruptcy,  insolvency,  reorganization  or similar case or proceeding with
respect to the  Guarantor,  the  Lender  shall have the right to file a proof of
claim,  claim or other similar  document and to recover a principal amount equal
to the outstanding  principal amount of the Liabilities of Power (other than its
Liabilities  under Section 11 of the Loan  Agreement)  not to exceed  $1,800,000
plus the outstanding  principal amount of the Liabilities of Process (other than
its  Liabilities  under  Section  11  of  the  Loan  Agreement)  not  to  exceed
$1,500,000, plus such interest and enforcement expenses referred to above.

     The Guarantor expressly  acknowledges that the Lender may assign certain of
its  rights and  claims  under the Loan  Agreement  and the Loan  Documents  (as
defined in the Loan Agreement) against Power, a portion of its security interest
in Power's assets and certain  related  rights,  claims and security  interests,
including,  without  limitation,  a portion of its rights  under this  Guarantee
relating to the  Liabilities of Power, to the  Export-Import  Bank of the United
States ("EximBank"). In the event of such an assignment:

     (a) the Lender  shall have the right at any time to  commence a  litigation
against the  Guarantor  and  exercise  any other  remedies  (including,  without
limitation,  filing  a  proof  of  claim,  claim  or  similar  document  in  any
bankruptcy, insolvency, reorganization or similar proceeding with respect to the
Guarantor) and to recover a principal amount equal to the outstanding  principal
amount of the Liabilities of Process (other than its  Liabilities  under Section
11 of the Loan  Agreement)  not to exceed  $1,500,000,  plus such  interest  and
enforcement expenses referred to above,

     (b) EximBank  shall have the right at any time to commence a litigation  in
the same or any other court of competent  jurisdiction against the Guarantor and
exercise any other remedies  (including,  without limitation,  filing a proof of
claim, claim or similar document in any bankruptcy,  insolvency,  reorganization
or  similar  proceeding)  and  to  recover  a  principal  amount  equal  to  the
outstanding  principal  amount  of the  Liabilities  of  Power  (other  than its
Liabilities  under Section 11 of the Loan  Agreement) not to exceed  $1,800,000,
plus such interest and enforcement expenses referred to above, and

     (c) the  Guarantor  shall not be  permitted  to assert  that its  liability
hereunder is limited to $1,800,000.

          The  liability  of the  Guarantor  under this  Guarantee  shall not be
affected by nor shall anything herein  contained be deemed to be a limitation on
the nature or the amount of loans,  advances or other  extensions of credit made
to the Borrower.  Such  continuing  liability shall not be reduced on account of
any payment or  performance  by the  Borrower,  but shall be reduced only to the
extent the Guarantor  makes  payments to the Bank on account of liability of the
Guarantor pursuant to this Guarantee.

          This  Guarantee  will  terminate  one  year  after  the  date  of this
Guarantee  but only to the extent it relates to  Liabilities  arising from Loans
and Lender Letters of Credit (as defined in the Loan  Agreement)  made or issued
after the effective  date of such  termination,  provided that such  termination
will not be effective unless the Guarantor gives at least thirty (30) days prior
written  notice to the Lender,  which must be receipted for by an officer of the
Lender. The Guarantor acknowledges and agrees that delivery of such notice shall
constitute an immediate  Event of Default under the Loan Agreement and,  without
limiting the rights and remedies  available to the Lender, the Lender shall have
the right to demand payment under and otherwise enforce this Guarantee.

          In the event of any such termination of this Guarantee,  the Guarantor
shall  nevertheless  remain  liable with respect to all  Liabilities  created or
arising prior to the  effective  date of  termination;  and with respect to such
Liabilities and any renewals and extensions,  and any Liabilities arising out of
them,  including,  without limitation,  interest,  fees and enforcement expenses
relating  thereto,  this Guarantee shall remain in full force and effect and the
Lender shall have all the rights herein  provided for as if no such  termination
had occurred.

          As used  in  this  Guarantee,  the  following  terms  shall  have  the
following meanings:

               (a) "Claims"  shall mean any and all claims,  rights and demands,
presently  existing  or  hereafter  arising,  and  all  interest  heretofore  or
hereafter  accrued  thereon,  and any and all  collateral or security  interests
relating  thereto and the proceeds  thereof,  which the Guarantor now has or may
hereafter have or acquire against the Borrower.

               (b) "Collateral"  shall mean any and all collateral  described in
any and  all  credit  accommodations,  notes,  loan  agreements,  and any  other
agreements  and  documents,  now or hereafter  existing,  creating,  evidencing,
guaranteeing,  securing, or relating to any or all of the Liabilities,  together
with all amendments, modifications, renewals or extensions thereof.

               The  Guarantor  hereby  grants to the Lender full power,  without
notice  to the  Guarantor,  and,  if there is more  than  one  Guarantor  liable
hereunder,  without in any way  affecting the joint and several  obligations  of
each  Guarantor  hereunder,  to  deal  in any  manner  with  the  Borrower,  the
Liabilities,  the Collateral  and with any other  Guarantor  hereunder,  and any
other guarantor of the Liabilities  including,  without limitation,  the powers:
(a) to  modify  or  otherwise  change  any  terms  of all  or  any  part  of the
Liabilities and/or the Collateral, to grant any extension or renewal thereof and
any  other  indulgence  with  respect  thereto,   and  to  effect  any  release,
subordination,  compromise  or  settlement  with  respect to the  Borrower,  the
Liabilities,  the  Collateral,  and  the  obligation  of any  one or more of the
Guarantors;  (b) to enter into any agreement of forbearance  with respect to all
or any  part  of the  Collateral,  or with  respect  to the  Liabilities  of the
Borrower or the obligations of any Guarantor, or to change the terms of any such
agreement;  (c) to forbear from calling for additional  collateral to secure any
of the Liabilities or to secure any obligation comprised in the Collateral;  and
(d) to consent to the substitution,  exchange,  or release of all or any part of
the Collateral,  whether or not the collateral,  if any,  received by the Lender
upon  such  substitution,  exchange,  or  release  shall  be of the same or of a
different character or value than the collateral surrendered by the Lender.

               The  Guarantor  waives  any  notice  of the  acceptance  of  this
Guarantee,  or of the  creation,  renewal or accrual of any of the  Liabilities,
present or future,  or of the  reliance of the Lender upon this  Guarantee.  The
Liabilities shall conclusively be presumed to have been created, contracted for,
incurred or suffered to exist in reliance upon this Guarantee,  and all dealings
between the Borrower and the Lender shall likewise be presumed to be in reliance
upon this  Guarantee.  The Guarantor  waives  protest,  presentment,  demand for
payment, notice of default or non-payment, and notice of dishonor to or upon the
Guarantor,  the Borrower,  or any other party liable for any of the Liabilities.
The Guarantor  acknowledges that this Guarantee and the Guarantor's  obligations
under this  Guarantee  are and shall at all times  continue to be  absolute  and
unconditional  in all respects,  and shall at all times be valid and enforceable
irrespective  of (a)  any  other  agreements  or  circumstances  of  any  nature
whatsoever which might otherwise  constitute a defense to this Guarantee and the
obligations of the Guarantor  under this  Guarantee,  (b) the obligations of any
other person or party (including,  without limitation, the Borrower) relating to
this  Guarantee,  or (c) the  obligations  of any  other  guarantor  under  this
Guarantee or otherwise with respect to the  Liabilities.  The obligations of the
Guarantor hereunder,  and the rights of the Lender in the Collateral,  shall not
be released, discharged or in any way affected, nor shall the Guarantor have any
rights  against  the  Lender  by reason  of the fact  that the  Lender  fails to
preserve any rights in the Collateral or take any action whatsoever in regard to
the  Collateral or that any of the  Collateral  may be in default at the time of
acceptance  thereof  by the  Lender or  later;  nor by reason of the fact that a
valid lien in any of the  Collateral may not be conveyed to, or created in favor
of the  Lender;  nor by  reason of the fact  that any of the  Collateral  may be
subject to  equities  or defenses or claims in favor of others or may be invalid
or defective  in any way; nor by reason of the fact that any of the  Liabilities
may be invalid or unenforceable  against the Borrower or any obligor thereon for
any  reason  whatsoever;  nor by  reason  of the  fact  that  the  value  of the
Collateral,  if any,  or the  financial  condition  of the  Borrower,  or of any
obligor on the Liabilities or any obligation  included in the Collateral may not
have been correctly  estimated or was thereafter  changed;  nor by reason of any
deterioration,  waste,  or loss  by  fire,  theft,  or  otherwise  of any of the
Collateral;  nor by reason of the release,  in whole or in part, with or without
consideration of the Collateral or any of it.

               Subject to the second  paragraph in this  Guarantee,  in case the
Borrower  shall  fail to pay all or any part of the  Liabilities  when due,  the
Guarantor  immediately  will pay to the  Lender the amount due and unpaid by the
Borrower under such  Liabilities,  in like manner as if such amount  constituted
the direct and primary obligation of the Guarantor. The Lender shall be entitled
to exercise  any rights and  remedies it may have under this  Guarantee  without
being obligated to resort first to the Collateral or to any other security or to
any  other  remedy  or  remedies  to  enforce   payment  or  collection  of  the
Liabilities,  and may pursue all or any of its  remedies at one or at  different
times. With respect to the Claims, the Guarantor hereby irrevocably subordinates
the  Claims  to the prior  payment  in full of all of the  Liabilities,  and the
Guarantor agrees that the Lender shall have the full right in its own name or in
the name of the  Guarantor to collect and enforce  such Claims by legal  action,
proof  of debt in  bankruptcy  or  other  liquidation  proceedings,  vote in any
proceeding for the arrangement of debts at any time proposed, or otherwise,  the
Lender  and  each  of  its  officers   being  hereby   irrevocably   constituted
attorneys-in-fact  for the Guarantor for the purpose of such enforcement and for
the purpose of endorsing in the name of the  Guarantor  any  instrument  for the
payment of money. In furtherance of such subordination,  but without limiting or
reducing the amount of the Guarantor's  obligations  under this  Guarantee,  the
Guarantor  will  receive  as  trustee  for the Lender and will pay to the Lender
forthwith upon receipt  thereof any amounts which the Guarantor may receive from
the Borrower on account of the Claims.  The Guarantor  agrees that no payment on
account  of such  Claims or any  security  interest  therein  shall be  created,
received,  accepted or retained nor shall any financing  statement be filed with
respect  thereto by the  Guarantor  unless and until the  Borrower  has paid and
satisfied  in full all the  Liabilities.  The  Lender is hereby  authorized  and
empowered, upon the occurrence of any Event of Default, to appropriate and apply
to the payment and extinguishment of the Liabilities of the Borrower any and all
Claims and payments  thereof,  without demand,  advertisement or notice,  all of
which are  hereby  expressly  waived,  and such  application  shall not limit or
reduce the amount of the Guarantor's obligations under this Guarantee.

               In the event  that the  Lender  shall  receive  any  payments  on
account of any of the Liabilities,  whether directly or indirectly, and it shall
subsequently be determined that such payments were for any reason improper, or a
claim  shall be made  against the Lender  that the same were  improper,  and the
Lender either  voluntarily or pursuant to court order shall return the same, the
Guarantor  shall be liable,  with the same  effect as if the said  payments  had
never been paid to, or received by, the Lender, for the amount of such repaid or
returned  payments,  notwithstanding  the fact  that  such  repaid  or  returned
payments may theretofore have been credited on account of the Liabilities or any
of them. If the Guarantee  hereunder with respect to any Guarantor would be held
or determined to be void,  invalid or  unenforceable on account of the amount of
such Guarantor's aggregate liability under this Guarantee,  then notwithstanding
any other provision of this Guarantee to the contrary,  the maximum liability of
such Guarantor hereunder shall be automatically limited and reduced to an amount
equal to the maximum amount that would not render this Guarantee with respect to
such   Guarantor   void,   invalid   or   unenforceable.   The   invalidity   or
unenforceability  of any  portion of this  Guarantee  shall in no way affect the
validity or enforceability of any other portion of this Guarantee.

               The Guarantor  hereby  irrevocably  waives for the benefit of the
Borrower and the Lender, and agrees that it will not exercise,  any rights which
it may have or  acquire  by way of  subrogation  under  this  Guarantee,  by any
payment made  hereunder or otherwise,  until all of the  Liabilities  shall have
been paid in full.  If any amount  shall be paid to the  Guarantor on account of
such subrogation  rights at any time when any of the Liabilities  shall not have
been paid in full,  such  amount  shall be held in trust for the  benefit of the
Lender and shall forthwith be paid to the Lender to be credited and applied upon
the Liabilities, whether matured or unmatured, in accordance with their terms.

               The Guarantor agrees to pay all reasonable  expenses  incurred by
the  Lender  (including,  without  limitation,  reasonable  attorneys'  fees and
disbursements) in connection with enforcement of this Guarantee.

               No delay on the part of the  Lender  in  exercising  any power or
right  hereunder  shall  operate  as a waiver  thereof;  nor shall any single or
partial  exercise of any power or right hereunder or the failure to exercise the
same in any instance  preclude other or further exercise thereof or the exercise
of any other power or right;  nor shall the Lender be liable for  exercising  or
failing to exercise any such power or right;  the rights and remedies  hereunder
expressly  specified are  cumulative and not exclusive of any rights or remedies
which the  Lender or anyone on whose  behalf it has acted or shall act as herein
provided, or its or his or their transferees, may or will otherwise have.

               All  payments   hereunder   shall  be  made  without  set-off  or
counterclaim  and free and clear of, and without  deduction  for, any present or
future  withholding or other taxes or duties,  including stamp duties,  or other
charges of any nature imposed on such payments by or on behalf of any government
or any political  subdivision or agency  thereof or therein.  If any such taxes,
duties or charges are so levied or imposed on any such  payment,  the  Guarantor
will make  additional  payments in such  amounts as may be necessary so that the
net amount received by the Lender, after deduction for or on account of all such
taxes,  duties or charges,  will be equal to the amount provided for herein. The
Guarantor shall furnish promptly to the Lender official receipts  evidencing the
payment  of any such  taxes,  duties  or  charges  paid by the  Guarantor.  This
paragraph  shall not apply to taxes  imposed  on the net income of the Lender by
the  United  States  of  America,  or the  State  of New  York or any  political
subdivision  thereof. In the event that the Lender actually receives a refund of
or  credit  for taxes in  respect  of which the  Guarantor  has made  additional
payments  to  the  Lender  under  this  paragraph  which  credit  or  refund  is
identifiable  by the  Lender as being a result of taxes in  respect of which the
Guarantor has made additional  payments to the Lender under this paragraph,  the
Lender shall promptly  notify the Guarantor and shall remit to the Guarantor the
amount of such refund or credit  (without  interest) up to but not exceeding the
lesser of (a) such additional  payment or payments by the Guarantor,  or (b) the
actual  after-tax  benefit to the Lender resulting from such refund or credit as
conclusively  determined  by the  Lender.  Nothing  contained  herein  shall (i)
obligate  the  Lender to apply for such a refund or credit or (b)  afford to the
Guarantor  any right to inspect or review any  financial  or tax  records of the
Lender.

               The term "the Lender" as used throughout this instrument shall be
deemed to include Dime Commercial  Corp.,  all of its branches and  departments,
and any individual,  partnership or corporation  acting as its nominee or agent,
and any  corporation  the  majority  of the  voting  stock  of which is owned or
controlled, directly or indirectly, by Dime Commercial Corp. or The Dime Savings
Bank of New York,  FSB. The term  "Borrower" as used  throughout this instrument
shall include the individual or individuals,  association,  partnership, limited
liability  company,  or corporations  named herein as the Borrower,  and (a) any
successor,  individual  or  individuals,  association,  partnership,  or limited
liability  company  or  corporations  to which all or  substantially  all of the
business or assets of the Borrower shall have been transferred,  (b) in the case
of a Borrower  which is a  partnership  or limited  liability  company,  any new
partnership or limited liability company which shall have been created by reason
of the admission of any new partner or partners or new member or members therein
or the  dissolution  of the existing  partnership  by the death,  resignation or
other  withdrawal  of any  partner or member,  and (c) in the case of a Borrower
which is a corporation,  any other  corporation  into or with which the Borrower
shall have been merged, consolidated, reorganized, purchased or absorbed.

               This Guarantee shall, without further reference,  pass to and may
be relied on and enforced by any  successor  or assignee of the Lender,  and any
transferee  or  subsequent  holder of any of the  Liabilities,  and the Borrower
and/or the  Guarantor  will not assert any claims it may have against the Lender
against  any such  assignee,  successor,  transferee,  or any  other  subsequent
holder.  Subject to the fifth paragraph in this  Guarantee,  this Guarantee is a
continuing  guarantee,  and is to remain  in full  force  and  effect  until the
termination of the Commitment (as defined in the Loan Agreement) and the payment
of all  Liabilities  of the  Borrower  to the Lender,  whether  now  existing or
hereafter  incurred,  notwithstanding  the  appointment of a receiver of, or the
dissolution of, and/or any other change in, or with respect to, the Borrower. No
change,  modification,  waiver,  or  discharge,  in whole  or in  part,  of this
Guarantee  shall be effective  unless in writing and signed by the party against
whom such change, modification, waiver, or discharge is sought to be enforced.

               THIS GUARANTEE SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED
BY THE LAW OF, THE STATE OF NEW YORK,  WITHOUT REGARD TO PRINCIPLES OF CONFLICTS
OF LAWS. THE GUARANTOR HEREBY AGREES THAT ANY LEGAL ACTION OR PROCEEDING AGAINST
THE GUARANTOR WITH RESPECT TO THIS GUARANTEE MAY BE BROUGHT IN THE COURTS OF THE
STATE OF NEW YORK IN THE CITY OF NEW YORK OR OF THE UNITED STATES OF AMERICA FOR
THE SOUTHERN DISTRICT OF NEW YORK AS THE LENDER MAY ELECT, AND, BY EXECUTION AND
DELIVERY  HEREOF,  THE  GUARANTOR  ACCEPTS  AND  CONSENTS  TO, FOR ITSELF AND IN
RESPECT OF ITS PROPERTY, GENERALLY AND UNCONDITIONALLY,  THE JURISDICTION OF THE
AFORESAID COURTS AND AGREES THAT SUCH  JURISDICTION  SHALL BE EXCLUSIVE,  UNLESS
WAIVED BY THE LENDER IN WRITING, WITH RESPECT TO ANY CLAIM, ACTION OR PROCEEDING
BROUGHT BY IT AGAINST THE LENDER AND ANY  QUESTIONS  RELATING TO USURY.  NOTHING
HEREIN  SHALL  LIMIT THE RIGHT OF THE LENDER TO BRING  PROCEEDINGS  AGAINST  THE
GUARANTOR IN ANY OTHER JURISDICTION.  THE GUARANTOR  IRREVOCABLY CONSENTS TO THE
SERVICE OF PROCESS IN ANY SUCH LEGAL ACTION OR PROCEEDING  BY PERSONAL  DELIVERY
OR BY THE MAILING THEREOF BY THE LENDER BY REGISTERED OR CERTIFIED MAIL,  RETURN
RECEIPT REQUESTED,  POSTAGE PREPAID,  TO THE ADDRESS SPECIFIED IN THE RECORDS OF
THE LENDER,  SUCH SERVICE OF PROCESS BY MAIL TO BE DEEMED EFFECTIVE ON THE FIFTH
DAY FOLLOWING  SUCH MAILING.  THE GUARANTOR  AGREES THAT A FINAL JUDGMENT IN ANY
SUCH LEGAL ACTION OR PROCEEDING  SHALL BE CONCLUSIVE  AND MAY BE ENFORCED IN ANY
MANNER PROVIDED BY LAW.

               The  Guarantor  has  made  an  independent  investigation  of the
Borrower and of the financial condition of the Borrower. The Lender has not made
and does not make any  representations  as to the  income,  expense,  operation,
finances or any other matter or thing  affecting the Borrower nor has the Lender
made any  representation  as to the amount or nature of the  Liabilities  of the
Borrower to which this Guarantee  applies as specifically  herein set forth, nor
has  the  Lender  or  any  officer,  agent  or  employee  of the  Lender  or any
representative  thereof,  made any other  oral  representations,  agreements  or
commitments  of  any  kind  or  nature,   and  the  Guarantor  hereby  expressly
acknowledges that no such  representations have been made. It is agreed that any
and all understandings and agreements heretofore made between the parties hereto
are  merged  in this  Guarantee,  and  that  this  Guarantee  alone,  fully  and
completely, expresses the understanding of such parties.

               If for the  purposes  of  obtaining  judgment  in any court it is
necessary to convert a sum due hereunder in U.S. Dollars into another  currency,
the parties hereto agree, to the fullest extent that they may effectively do so,
that the rate of exchange used shall be that at which in accordance  with normal
banking  procedures  the Lender  could  purchase  U.S.  Dollars  with such other
currency in New York City on the business day (being any day on which commercial
banks are open for domestic and international  business  (including  dealings in
foreign  exchange) in New York City)  preceding  that on which final judgment is
given.  The obligation of the Guarantor in respect of any sum due from it to the
Lender  hereunder shall,  notwithstanding  any judgment in a currency other than
U.S.  Dollars,  be  discharged  only  to the  extent  that on the  business  day
following  receipt by the Lender of any sum  adjudged to be so due in such other
currency the Lender may in accordance  with normal banking  procedures  purchase
U.S. Dollars with such other currency; if the U.S. Dollars so purchased are less
than the sum originally due to the Lender in U.S. Dollars, the Guarantor agrees,
as a separate obligation and notwithstanding any such judgment, to indemnify the
Lender  against such loss, and if the U.S.  Dollars so purchased  exceed the sum
originally due to the Lender in U.S. Dollars,  the Lender agrees to remit to the
Guarantor such excess.

               NO CLAIM MAY BE MADE BY ANY  GUARANTOR  AGAINST THE LENDER OR THE
AFFILIATES,  DIRECTORS,  OFFICERS, EMPLOYEES,  ATTORNEYS OR AGENTS OF THE LENDER
FOR ANY SPECIAL,  INDIRECT OR  CONSEQUENTIAL  DAMAGES OR, TO THE FULLEST  EXTENT
PERMITTED BY LAW,  FOR ANY PUNITIVE  DAMAGES IN RESPECT OF ANY CLAIM OR CAUSE OF
ACTION  (WHETHER  BASED ON CONTRACT,  TORT,  STATUTORY  LIABILITY,  OR ANY OTHER
GROUND) BASED ON, ARISING OUT OF OR RELATED TO THIS  GUARANTEE,  THE LIABILITIES
OR THE TRANSACTIONS  CONTEMPLATED HEREBY OR ANY ACT, OMISSION OR EVENT OCCURRING
IN CONNECTION THEREWITH,  AND EACH GUARANTOR HEREBY WAIVES,  RELEASES AND AGREES
NEVER TO SUE UPON ANY CLAIM FOR ANY SUCH DAMAGES,  WHETHER SUCH CLAIM NOW EXISTS
OR HEREAFTER  ARISES AND WHETHER OR NOT IT IS NOW KNOWN OR SUSPECTED TO EXIST IN
ITS FAVOR.

               TO THE EXTENT  PERMITTED BY APPLICABLE LAW, THE GUARANTOR  WAIVES
THE RIGHT TO INTERPOSE  COUNTERCLAIMS,  CROSS-CLAIMS  OR SETOFFS OF ANY KIND AND
DESCRIPTION  AND ALL DEFENSES  (OTHER THAN PAYMENT IN FULL OF ALL LIABILITIES IN
CASH) IN ANY LITIGATION ARISING HEREUNDER.

               AFTER REVIEWING THIS PROVISION  SPECIFICALLY  WITH ITS RESPECTIVE
COUNSEL, EACH OF THE GUARANTOR AND THE LENDER HEREBY KNOWINGLY,  VOLUNTARILY AND
INTENTIONALLY  WAIVE ANY AND ALL RIGHTS THE GUARANTOR AND THE LENDER MAY HAVE TO
A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED ON, OR ARISING OUT OF, UNDER,
OR IN  CONNECTION  WITH,  THIS  GUARANTEE  OR ANY COURSE OF  CONDUCT,  COURSE OF
DEALING, STATEMENTS (WHETHER VERBAL OR WRITTEN) OR ACTIONS OF THE GUARANTOR, THE
