Exhibit 10.53

                            INDEMNIFICATION AGREEMENT

          THIS INDEMNIFICATION AGREEMENT ("Agreement") is made as of this 26th
day of July 2001, by and between NQL INC., a Delaware corporation (the
"Company"), and Matthew C. Harrison, Jr. ("Indemnitee"), a director and/or
officer of the Company.

          WHEREAS, the Company and Indemnitee recognize the increasing
difficulty in obtaining directors' and officers' liability insurance, the
significant increases in the cost of such insurance and the general reductions
in the coverage of such insurance;

          WHEREAS, the Company and Indemnitee further recognize the substantial
increase in corporate litigation subjecting officers and directors to expensive
litigation risks at the same time that liability insurance has been severely
limited;

          WHEREAS, Indemnitee does not regard the current protection available
as adequate given the present circumstances, and Indemnitee and other officers
and directors of the Company may not be willing to serve as officers and
directors without adequate protection;

          WHEREAS, the Company desires to attract and retain the services of
highly qualified individuals, such as Indemnitee, to serve as officers and
directors of the Company and to indemnify its officers and directors so as to
provide them with the maximum protection permitted by law;

          NOW, THEREFORE, the Company and Indemnitee hereby agree as follows:

                                       I.

                                 INDEMNIFICATION

          1.01 Third Party Proceedings. The Company shall indemnify Indemnitee
if Indemnitee is or was a party or is threatened to be made a party to any
threatened, pending or complete action, suit or proceeding, whether civil,
criminal, administrative or investigative (other than action by or in the right
of the Company) by reason of the fact that Indemnitee is or was a director
and/or officer of the Company or any subsidiary of the Company, by reason of any
action or inaction on the part of Indemnitee while a director and/or officer or
by reason of the fact that Indemnitee is or was serving at the request of the
Company as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, against all expense,
liability and loss (including attorneys' fees), judgments, fines and amounts
paid in settlement (if such settlement is approved in advance by the Company,
which approval shall not be unreasonably withheld) actually and reasonably
incurred by Indemnitee in connection with such action, suit or proceeding if
Indemnitee acted in good faith and in a manner Indemnitee

<PAGE>

reasonably believed to be in the best interests of the Company, and, with
respect to any criminal action or proceeding, had no reasonable cause to believe
Indemnitee's conduct was unlawful.

          The termination of any action, suit or proceeding by judgment, order,
settlement, conviction, or upon a plea of nolo contendere or its equivalent,
shall not, of itself, create a presumption that Indemnitee did not act in good
faith and in a manner which Indemnitee reasonably believed to be in the best
interests of the Company, and with respect to any criminal action or proceeding,
had reasonable cause to believe that Indemnitee's conduct was unlawful.

          1.02 Proceedings by or in the Right of the Company. The Company shall
indemnify Indemnitee if Indemnitee was or is a party or is threatened to be made
a party to any threatened, pending or completed action or suit by or in the
right of the Company or any subsidiary of the Company to procure a judgment in
its favor by reason of fact that Indemnitee is or was a director and/or officer
of the Company or any subsidiary of the Company, by reason of any action or
inaction on the part of Indemnitee while a director and/or officer or by reason
of the fact that Indemnitee is or was serving at the request of the Company as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, against all expense, liability and loss
(including attorneys' fees) and amounts paid in settlement (if such settlement
is court-approved) actually and reasonably incurred by Indemnitee in connection
with the defense or settlement of such action or suit if Indemnitee acted in
good faith and in a manner Indemnitee reasonably believed to be in the best
interests of the Company and its shareholders. No indemnification shall be made
in respect of any claim, issue or matter as to which Indemnitee shall have been
adjudged to be liable to the Company in the performance of Indemnitee's duties
to the Company and its shareholders, unless and only to the extent that the
Court in which such proceeding is or was pending shall determine upon
application that, in view of all the circumstances of the case, Indemnitee is
fairly and reasonably entitled to indemnity for expenses and then only to the
extent that the court shall determine.

          1.03 Mandatory Payment of Expenses. To the extent that Indemnitee has
been successful on the merits or otherwise in defense of any action, suit or
proceeding referred to in Section 1.01 or 1.02 or the defense of any claim,
issue or matter therein, Indemnitee shall be indemnified against expenses
(including attorneys' fees) actually and reasonably incurred by Indemnitee in
connection therewith.

                                       II.

                       EXPENSES; INDEMNIFICATION PROCEDURE

          2.01 Advancement of Expenses. The Company shall advance all expenses
incurred by Indemnitee in connection with the investigation, defense, settlement
or appeal of any civil or criminal action, suit or proceeding referenced in
Section 1.01 or 1.02 hereof. Indemnitee hereby undertakes to repay such amounts
advanced only if, and to the extent that, it shall ultimately be determined that
Indemnitee is not entitled to be indemnified by the Company as authorized
hereby. The advance to be made hereunder shall be paid by the Company to
Indemnitee within thirty (30) days following delivery of a written request
therefor by Indemnitee to the Company.

                                       -2-
<PAGE>

          2.02 Determination of Conduct. Any indemnification (unless ordered by
a court) shall be made by the Company only as authorized in the specific case
upon a determination that indemnification of Indemnitee is proper under the
circumstances because Indemnitee has met the applicable standard of conduct set
forth in Section 1.01 or 1.02 of this Agreement. Such determination shall be
made by any of the following: (1) the Board of Directors (or by an executive
committee thereof) by a majority vote of a quorum consisting of directors who
were not parties to such action, suit or proceeding, (2) if such a quorum is not
obtainable, or, even if obtainable, if a quorum of disinterested directors so
directs, by independent legal counsel in a written opinion, (3) by the
shareholders, with the shares owned by Indemnitee not being entitled to vote
thereon, or (4) the court in which such proceeding is or was pending upon
application made by the Company or Indemnitee or the attorney or other person
rendering service in connection with the defense, whether or not such
application by Indemnitee, the attorney or the other person is opposed by the
Company.

          2.03 Notice/Cooperation by Indemnitee. Indemnitee shall, as a
condition precedent to his or her right to be indemnified under this Agreement,
give the Company notice in writing as soon as practicable of any claim made
against Indemnitee for which indemnification will or could be sought under this
Agreement. Notice to the Company shall be directed to NQL Inc., 4 Hutton Centre
Drive, Suite 500, South Coast Metro, California 92707, or such other address as
the Company shall designate in writing to Indemnitee. Notice shall be deemed
received on the third business day after the date postmarked if sent by domestic
certified or registered mail, properly addressed; otherwise, notice shall be
deemed received when such notice shall actually be received by the Company. In
addition, Indemnitee shall give the Company such information and cooperation as
it may reasonably require and as shall be within Indemnitee's power.

          2.04 Notice to Insurers. If, at the time of the receipt of a notice of
a claim pursuant to Section 2.03 hereof, the Company has director and officer
liability insurance in effect, the Company shall give prompt notice of the
commencement of such proceeding to the insurers in accordance with the
procedures set forth in the respective policies. The Company shall thereafter
take all necessary or desirable actions to cause such insurers to pay, on behalf
of the Indemnitee, all amounts payable as a result of such proceeding in
accordance with the terms of such policies.

          2.05 Selection of Counsel. In the event the Company shall be obligated
under Section 2.01 hereof to pay the expenses of any proceeding against
Indemnitee, the Company, shall be entitled to assume the defense of such
proceeding, with counsel approved by Indemnitee, upon the delivery to Indemnitee
of written notice of its election so to do. After delivery of such notice,
approval of such counsel by Indemnitee and the retention of such counsel by the
Company, the Company will not be liable to Indemnitee under this Agreement for
any fees of counsel subsequently incurred by Indemnitee with respect to the same
proceeding, provided that (a) Indemnitee shall have the right to employ his or
her counsel in any such proceeding at Indemnitee's expense; and (b) if (i) the
employment of counsel by Indemnitee has been previously authorized by the
Company, (ii) Indemnitee shall have reasonably concluded that there may be a
conflict of interest between the Company and Indemnitee in the conduct of any
such defense, or (iii) the Company shall not, in fact, have employed counsel to
assume the

                                      -3-
<PAGE>

defense of such proceeding, then the fees and expenses of Indemnitee's counsel
shall be at the expense of the Company.

                                      III.

               ADDITIONAL INDEMNIFICATION RIGHTS; NON-EXCLUSIVITY

          3.01 Application. The provisions of this Agreement shall be deemed
applicable to all actual or alleged actions or omissions by Indemnitee during
any and all periods of time that Indemnitee was, is, or shall be serving as a
director and/or officer of the Company.

          3.02 Scope. The Company hereby agrees to indemnify Indemnitee to the
fullest extent permitted by law (except as set forth in Article VIII hereof),
notwithstanding that such indemnification is not specifically authorized by the
other provisions of this Agreement, the Company's Certificate of Incorporation,
the Company's Bylaws or by statute. In the event of any changes, after the date
of this Agreement, in any applicable law, statute, or rule which expands the
right of a Delaware corporation to indemnify a member of its board of directors
or an officer, such changes shall be, ipso facto, within the purview of
Indemnitee's rights and the Company's obligations under this Agreement. In the
event of any change in any applicable law, statute, or rule which narrows the
right of a Delaware corporation to indemnify a member of its board of directors
or an officer, such changes, to the extent not otherwise required by such law,
statute or rule to be applied to this Agreement shall have no effect on this
Agreement or the parties' rights and obligations hereunder.

          3.03 Non-Exclusivity. The indemnification provided by this Agreement
shall not be deemed exclusive of any rights to which an Indemnitee may be
entitled under the Company's Certificate of Incorporation, its Bylaws, any
agreement, any vote of shareholders or disinterested directors, the Delaware
General Corporation Law, or otherwise, both as to action in Indemnitee's
official capacity and as to action in another capacity while holding such
office. The indemnification provided under this Agreement shall continue as to
Indemnitee for an action taken or not taken while serving in an indemnified
capacity even though he or she may have ceased to serve in such capacity at the
time of any action, suit or other covered proceeding.

                                       IV.

                             PARTIAL INDEMNIFICATION

          4.01 If Indemnitee is entitled under any provision of this Agreement
to indemnification by the Company for some or a portion of the expenses,
judgments, fines or penalties actually or reasonably incurred by him in the
investigation, defense, appeal or settlement of any civil or criminal action,
suit or proceeding, but not, however, for the total amount thereof, the Company
shall nevertheless indemnify Indemnitee for the portion of such expenses,
judgments, fines or penalties to which Indemnitee is entitled.

                                       V.

                              MUTUAL ACKNOWLEDGMENT

          5.01 Both the Company and Indemnitee acknowledge that in certain
instances, federal law or public policy may override applicable state law and
prohibit the Company from indemnifying its directors and officers under this
Agreement or otherwise. For example, the Company and Indemnitee acknowledge that
the Securities and Exchange Commission (the "SEC") has taken the position that
indemnification is not permissible for liabilities arising under certain federal
securities laws, and federal legislation prohibits indemnification for certain
ERISA violations. Indemnitee understands and acknowledges that the Company has
undertaken or may be required in the future to undertake with the SEC to submit
the question of indemnification to a court in certain circumstances for a
determination of the Company's right under public policy to indemnify
Indemnitee.

                                       VI.

                  DIRECTORS' AND OFFICERS' LIABILITY INSURANCE

          6.01 The Company shall, from time to time, make the good faith
determination whether or not it is practicable for the Company to obtain and
maintain a policy or policies of insurance with reputable insurance companies
providing the directors and officers with coverage for losses from wrongful
acts, or to ensure the Company's performance of its indemnification obligations
under this Agreement. Among other considerations, the Company will weigh the
costs of obtaining such insurance coverage against the protection afforded by
such coverage. In all policies of directors' and officers' liability insurance,
Indemnitee shall be named as an insured in such a manner as to provide
Indemnitee the same rights and benefits as are accorded to the most favorably
insured of the Company's directors, if Indemnitee is a director; or of the
Company's officers, if Indemnitee is not a director of the Company but is an
officer. Notwithstanding the foregoing, the Company shall have no obligation to
obtain or maintain such insurance if the Company determines in good faith that
such insurance is not reasonably available, if the premium costs for such
insurance are disproportionate to the amount of coverage provided, if the
coverage provided by such insurance is limited by exclusions so as to provide an
insufficient benefit, or if Indemnitee is covered by similar insurance
maintained by a parent or subsidiary of the Company.

                                      VII.

                                  SEVERABILITY

          7.01 Nothing in this Agreement is intended to require or shall be
construed as requiring the Company to do or fail to do any act in violation of
applicable law. The Company's inability, pursuant to court order, to perform its
obligations under this Agreement shall not constitute a breach of this
Agreement. The provisions of this Agreement shall be severable as provided in
this Article VII. If this Agreement or any portion hereof shall be invalidated
on any ground by any court of competent jurisdiction, then the Company shall
nevertheless indemnify

                                      -5-
<PAGE>

Indemnitee to the full extent permitted by any applicable portion of this
Agreement that shall not have been invalidated, and the balance of this
Agreement not so invalidated shall be enforceable in accordance with its terms.

                                      VIII.

                                   EXCEPTIONS

          8.01 Any other provision to the contrary notwithstanding, the Company
shall not be obligated pursuant to the terms of this Agreement for the
following:

               (a) Claims Initiated by Indemnitee. To indemnify or advance
expenses to Indemnitee with respect to proceedings or claims initiated or
brought voluntarily by Indemnitee and not by way of defense, unless said
proceedings or claims were authorized by the board of directors of the Company.

               (b) Improper Personal Benefit. To indemnify Indemnitee against
liability for any transactions from which Indemnitee derived an improper
personal benefit, including, but not limited to, self-dealing or usurpation of a
corporate opportunity.

               (c) Dishonesty. To indemnify Indemnitee if a judgment or other
final adjudication adverse to Indemnitee established that Indemnitee committed
acts of active and deliberate dishonesty, with actual dishonest purpose and
intent, which acts were material to the cause of action so adjudicated.

               (d) Insured Claims. To indemnify Indemnitee for expenses or
liabilities of any type whatsoever (including, but not limited to, judgments,
fines, ERISA excise taxes or penalties, and amounts paid in settlement) which
have been paid directly to Indemnitee by an insurance carrier under a policy of
officers' and directors' liability insurance maintained by the Company.

               (e) Claims Under Section 16(b). To indemnify Indemnitee for
expenses or the payment of profits arising from the purchase and sale by
Indemnitee of securities in violation of Section 16(b) of the Securities
Exchange Act of 1934, as amended, or any similar successor statute.

                                       IX.

                                  MISCELLANEOUS

          9.01 Construction of Certain Phrases.

               (a) For purposes of this Agreement, references to the "Company"
shall include any constituent corporation (including any constituent of a
constituent) absorbed in a consolidation or merger so that if Indemnitee is or
was a director, officer, employee or agent of such constituent corporation, or
is or was serving at the request of such constituent corporation as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust or

                                      -6-
<PAGE>

other enterprise, Indemnitee shall stand in the same position under the
provisions of this Agreement with respect to the resulting or surviving
corporation as Indemnitee would have with respect to such constituent
corporation if its separate existence had continued.

               (b) For purposes of this Agreement, references to "other
enterprises" shall include employee benefit plans; references to "fines" shall
include any excise taxes assessed on Indemnitee with respect to an employee
benefit plan; and references to "serving at the request of the Company" shall
include any service as a director, officer, employee or agent of the Company
which impose duties on, or involves services by, such director, officer,
employee or agent with respect to an employee benefit plan, its participants, or
beneficiaries; and if Indemnitee acted in good faith and in a manner Indemnitee
reasonably believed to be in the best interests of the participants and
beneficiaries of an employee benefit plan, Indemnitee shall be deemed to have
acted in a manner "reasonably believed to be in the best interests of the
Company and its shareholders" as referred to in this Agreement.

                  9.02 Successors and Assigns. This Agreement shall be binding
upon the Company and its successors and assigns, and shall insure to the benefit

                      FIRST AMENDMENT TO LOAN AND SECURITY
                         AGREEMENT AND RELATED DOCUMENTS

     This First Amendment to Loan and Security  Agreement and Related  Documents
("Amendment")  of August 15, 2001, by and among DELTA  COMPUTEC INC., a New York
corporation,  having  its  principal  place of  business  located  at 900 Huyler
Street,  Teterboro,  New  Jersey  07608  ("Borrower"),   NQL  INC.,  a  Delaware
corporation,  having an address at 4 Hutton Centre Drive, Suite 500, South Coast
Metro, California 92707 ("Guarantor",  together with Borrower, being hereinafter
sometimes  collectively  referred to as the  "Obligors"),  and KELTIC  FINANCIAL
PARTNERS, LP, having offices at 555 Theodore Fremd Avenue, Suite C-209, Rye, New
York 10580 ("Lender").

                                    RECITALS:

     A. Borrower and Guarantor  have executed and delivered to Lender and/or one
or more of its predecessors in interest,  one or more promissory  notes,  letter
agreements, loan agreements, security agreements, pledge agreements,  collateral
assignments and other agreements, instruments,  certificates and documents, some
or all of which are described on attached Exhibit A, which is annexed hereto and
made a part  hereof  (collectively,  as  amended  from  time to time,  the "Loan
Documents"),  and  which  evidence  or  secure  some  or all  of the  Borrower's
obligations  to Lender for one or more loans or other  extensions of credit (the
"Obligations").

     B. The  Borrower  and the  Lender  desire  to amend the Loan  Documents  as
provided for in this Amendment.

     NOW,  THEREFORE,  for and in  consideration  of the mutual covenants herein
contained,   and  other  good  and  valuable  consideration,   the  receipt  and
sufficiency of which is hereby acknowledged, it is agreed as follows:

1.   Reaffirmation of Recitals.  The Obligors and the Lender hereby  acknowledge
and agree that the recitations  contained in the recitals noted above,  together
with the  information  set forth on the  Exhibits  attached  hereto are true and
complete,  and that all such recitations and information are deemed incorporated
into this Amendment by reference as if set forth herein at length.

2.   Definitions.

         Unless  otherwise  defined herein,  all  capitalized  terms used herein
shall have the meaning set forth in the Loan Documents.

3.   Ratification of Existing Agreements.

     (a)  Obligors  acknowledge  that all of the  Obligations  to the  Lender as
evidenced by or otherwise arising under the Loan Documents,  except as otherwise
expressly  modified  in this

<PAGE>

Amendment  upon the  terms set forth  herein  and  therein,  are,  by  Obligors'
execution of this Amendment,  ratified and confirmed in all respects and without
condition. The Obligors  unconditionally  acknowledge and agree and confirm that
they are  absolutely  liable and  indebted  to the  Lender for all  indebtedness
evidenced by the Loan Documents.  Each of the Obligors  acknowledges that all of
the Obligations are joint and several.  In addition,  by Obligors'  execution of
this Amendment,  Obligors  represent and warrant that no counterclaim,  right of
set-off, recoupment or defense of any kind exists or is outstanding with respect
to the  Obligations.  As of August 13, 2001,  there remains due under the Credit
Facility,  the  principal sum of  $848,298.14,  together with accrued and unpaid
interest.

     (b) Obligors  acknowledge that (i) the Collateral  securing the Obligations
constitutes  a valid  lien  and  security  interest  therein;  (ii)  each of the
Obligors shall take no action to impair or invalidate the security interests and
liens  granted  by said  Obligor  to the  Lender;  and (iii)  all such  security
interests and liens shall  continue  unimpaired and in full force and effect and
shall cover and secure all of the Obligations.

4.   Representations and Warranties.

     The Obligors, as applicable, represent and warrant that:

          (a)  Obligors  are  justly  indebted  to the  Lender  as set  forth in
Paragraph 3 hereof.

          (b) The Obligors  expressly  acknowledge  that each of the instruments
and agreements, to which they are a party, evidencing, governing and/or securing
the  Obligations  are good,  valid,  enforceable,  and supported by  appropriate
consideration, which shall remain in full force and effect until paid in full in
accordance with the terms of each such Obligation, as modified herein.

          (c) All of their respective representations and warranties in the Loan
Documents to which each of the Obligors is a party are,  except as may otherwise
be stated in Section  4(d) below or elsewhere  in this  Amendment,  (i) true and
correct as of the date hereof,  (ii) ratified and confirmed without condition as
if made anew; and (iii) incorporated into this Amendment by reference.

          (d) No default or Event of Default or event which, with the passage of
time or the  giving of notice or both,  would  constitute  an Event of  Default,
exists  under any Loan  Document  which will not be cured by the  execution  and
effectiveness  of this Amendment;  except that the Obligors are in default under
the  Loan  Documents  due to the  Material  Adverse  Effect  in the  Guarantor's
financial condition.

          (e) No consent,  approval,  order or authorization of, or registration
or filing with,  any third party is required in connection  with the  execution,

          (f) This Amendment has been duly authorized, executed and delivered so
that it  constitutes  the legal,  valid and binding  obligation of the Obligors,
enforceable in accordance with its terms.

5.   Modifications: (a) Any and all references to any Loan Document in any other
Loan Document  shall be deemed to refer to such Loan Document as amended by this
Amendment.  This  Amendment  is  deemed  incorporated  into  each  of  the  Loan
Documents.  To the extent that any term or provision of this Amendment is or may
be inconsistent  with any term or provision in any Loan Document,  the terms and
provisions of this Amendment shall control.

     (b) The Loan and Security  Agreement  and the  Subordination  Agreement are
hereby  modified  to provide  that,  from and after the date of this  Amendment,
until full and final payment and performance of the Obligations,  Borrower shall
not  make  any  payments,  directly  or  indirectly,  to or for the  benefit  of
Guarantor,  whether by way of dividend or any other  distribution or transfer of
any kind, including without limitation, payments relating to Guarantor's payroll
and other operating  expenses,  except as set forth in the following sentence or
as otherwise consented to in writing by Lender, which consent may be withheld in
Lender's   sole  and  absolute   discretion.   Notwithstanding   the   aforesaid
prohibition,  Borrower shall,  for a period of no more than ninety (90) days, be
authorized to fund and/or pay Guarantor's  payroll  expenses in an amount not to
exceed  $42,000.00 per month  relating to the following  employees of Guarantor,
who are also  performing  services for the benefit of Borrower:  David  Pallman,
John Ross, Christopher Hunter, Jeannie Ho and Heather Vuncanon.

     (c)  Expect  as  amended  hereby,  the  terms  and  provisions  of the Loan
Documents remain unchanged, are and shall remain in full force and effect unless
and until modified or amended in writing in accordance with their terms, and are
hereby  ratified  and  confirmed.  Except as  expressly  provided  herein,  this
Amendment  shall not  constitute an amendment,  waiver,  consent or release with
respect to any provision of any Loan Document,  a waiver of any default or Event
of  Default  under  any Loan  Document,  or a waiver  or  release  of any of the
Lender's rights and remedies (all of which are hereby reserved).

6.   Conditions:  Lender's execution  and  delivery of this  Amendment  shall be
subject to the satisfaction of the following conditions:

     (a) On the execution of this  Amendment,  Borrower  shall pay to the Lender
all costs and  expenses  incurred by the Lender to the date  hereof,  including,
without limitation, legal fees and costs.

     (b) On or before  the  execution  of this  Amendment,  the  Obligors  shall
execute  and/or deliver or cause to be executed  and/or  delivered to the Lender
any additional  documentation or information as shall be reasonably requested by
the Lender.

7.  Release of Lender. By execution of this Amendment, each of the Obligors, for
themselves and their heirs, executors, personal representatives,  successors and
assigns,

                                       3
<PAGE>

jointly and severally  hereby  acknowledge and confirm that they do not have any
offsets,  defenses, rights of recoupment or claims of any kind or nature against
the Lender or any of its  officers,  agents,  directors  or  employees,  whether
asserted  or  unasserted  arising  from  or in any  way  relating  to  the  Loan
Documents,  this Amendment,  the Obligations and the  transactions  contemplated
thereby or  hereby.  To the extent  that they may have such  offsets,  defenses,
rights  of  recoupment  or  claims,  each of the  Obligors  and  each  of  their
respective successors, assigns, parents, subsidiaries, affiliates, predecessors,
employees,   agents,  heirs,  executors,   and  personal   representatives,   as
applicable, jointly and severally, release and forever discharge the Lender, its
subsidiaries,  affiliates, officers, directors, shareholders, employees, agents,
attorneys,  successors and assigns,  both present and former  (collectively  the
"Lender  Affiliates"),  of and from any and all  manner of action  and  actions,
cause and causes of action,  suits, debts,  controversies,  damages,  judgments,
executions, claims and demands whatsoever,  asserted or unasserted, in law or in
equity which against the Lender and/or the Lender  Affiliates they ever had, now
have or which any of the Obligors' successors,  assigns, parents,  subsidiaries,
affiliates,  predecessors,  employees,  agents,  heirs,  executors,  or personal
representatives,  as applicable,  both present and former,  ever had or now has,
upon or by reason of any manner,  cause, causes or thing whatsoever,  including,
without  limitation,  any  presently  existing  claim or defense  whether or not
presently suspected, contemplated or anticipated.

     It is understood and agreed that the release set forth hereinabove will not
be impaired or otherwise  affected by the  occurrence of an Event of Default and
the Lender's exercise of any rights and remedies available to it. The provisions
of this  Section  7 shall  be  effective  and  binding  upon  the  Obligors  and
enforceable by the Lender as of the date of this Amendment.

8.   Entire Agreement;  Binding  Affect.  The Loan  Documents and this Amendment
constitute  the entire and final  agreement  among the  parties and there are no
agreements,  understandings,  warranties or  representations  among the parties.
This  Amendment  will  inure  to the  benefit  and bind  the  respective  heirs,
administrators, executors, representatives,  successors and permitted assigns of
the parties hereto.

9.   Severability. If any clause or provision of this Amendment determined to be
illegal,  invalid or unenforceable  under any present or future law by the final
judgment of a court of competent  jurisdiction,  the remainder of this Amendment
will not be affected  thereby.  It is the  intention  of the parties that if any
such provision is held to be invalid,  illegal or  unenforceable,  there will be
added in lieu  thereof a provision  as similar in terms to such  provision as is
possible, and that such added provision will be legal, valid and enforceable.

10.  Headings;  Interpretation.  All headings  contained in this  Amendment  for
reference purposes only and are not intended to affect in any way the meaning or
interpretation  of this Amendment.  In this Amendment the singular  includes the

as including all statutory provisions  consolidating,  amending or replacing the
statute  referred  to; the word "or" shall be deemed to  include  "and/or",  the

INTENTIONALLY  WAIVES ANY RIGHT IT MAY HAVE OR HEREAFTER HAVE TO A TRIAL BY JURY
IN RESPECT OF ANY SUIT, ACTION OR PROCEEDING  ARISING OUT OF OR RELATING TO THIS

CERTIFY  THAT  NEITHER  THE  LENDER  NOR ANY OF ITS  REPRESENTATIVES,  AGENTS OR

all  aspects of and the basis for this  Amendment  and/or  have chosen not to so
review and  investigate (in which case,  each of the Obligors  acknowledges  and
agrees that it has knowingly and upon the advice of counsel  waived any claim or
defense  based  on any  fact or  knowledge  that any  investigation  would  have
disclosed), including without limitation:

          (i) the risks and benefits of the various waivers of rights  contained
          in this  Amendment,  including  but not  limited to, the waiver of the
          right to a jury trial; and
