               iv. The Borrower shall have filed all UCC financing statements in

     5. Representations and Warranties. To induce each Lender, severally and not

Lender that at and as of the date hereof:

          a. The Borrower has been duly incorporated and is validly existing and
in good standing under the laws of the state of Delaware, with full corporate
power and authority to own, lease and operate its properties and to conduct its
business as currently conducted. The Borrower is duly qualified as a foreign
entity to do business and is in good standing in every jurisdiction in which its
ownership of property or the nature of the business conducted by it makes such
qualification necessary and where the failure so to qualify would have a
Material Adverse Effect. "Material Adverse Effect" means any material adverse
effect on the ability of the Borrower to perform its obligations hereunder or on
the business, operations, properties, prospects or financial condition of the
Borrower.

          b. Each of the Loan Documents has been duly authorized, validly
executed and delivered on behalf of the Borrower and is a valid and binding
obligation of the Borrower enforceable against the Borrower in accordance with
its terms, subject to limitations on enforcement by general principles of equity
and by bankruptcy or other laws affecting the enforcement of creditors' rights
generally, and the Borrower has full power and authority to execute and deliver
this Agreement and the Loan Documents and to perform its obligations hereunder
and thereunder.

          c. The execution, delivery and performance of this Agreement and the
Loan Documents will not (i) conflict with or result in a breach of or a default
under any of the terms or provisions of, (A) the Borrower's certificate of
incorporation or by-laws, or (B) any material provision of any indenture,
mortgage, deed of trust or other material agreement or instrument to

                                       2

<PAGE>

which the Borrower is a party or by which it or any of its material properties
or assets is bound, (ii) result in a violation of any material provision of any
law, statute, rule, regulation, or any existing applicable decree, judgment or
order by any court, Federal or state regulatory body, administrative agency, or
other governmental body having jurisdiction over the Borrower, or any of its
material properties or assets or (iii) result in the creation or imposition of
any material lien, charge or encumbrance upon any material property or assets of
the Borrower or any of its subsidiaries pursuant to the terms of any agreement
or instrument to which any of them is a party or by which any of them may be
bound or to which any of their property or any of them is subject.

          d. No consent, approval or authorization of or designation,
declaration or filing with any governmental authority on the part of the
Borrower is required in connection with the valid execution and delivery of this
Agreement or the Loan Documents.

All representations and warranties made by the Borrower under or in connection
with this Agreement shall survive the making of the Loans and issuance and
delivery of the Note to the Lenders, notwithstanding any investigation made by
the Lenders or on the Lenders' behalf. All statements contained in any
certificate or financial statement delivered by the Borrower to the Lenders
under this Agreement or any other Loan Document shall constitute representations
and warranties made by the Borrower hereunder.

     6. Events of Default; Remedies. Upon the occurrence of any of the following

principal outstanding after the date such payment shall become due and payable
hereunder; or

          b. the Borrower shall fail to make any payment of interest after the
date such interest shall become due and payable hereunder; or

          c. any representation, warranty, covenant or certification made by the
Borrower herein, in the Notes, any other Loan Document or in any certificate or
financial statement shall prove to have been false or incorrect or breached in a
material respect on the date as of which made; or

          d. the Borrower or any of its subsidiaries shall (i) default in any
payment of any amount or amounts of principal of or interest on any indebtedness
for borrowed money (the "Indebtedness") (other than the Indebtedness hereunder)
the aggregate principal amount of which Indebtedness of all such persons is in
excess of $100,000, whether such Indebtedness now exists or shall hereinafter be

indebtedness to be due and payable, and such indebtedness has not been

annulled within twelve (12) business days of such acceleration, or (ii) default
in the observance or performance of any other agreement or condition relating to
any Indebtedness in excess of $100,000 or contained in any instrument or
agreement evidencing, securing or relating thereto, or any other event shall
occur or condition exist, the effect of which default or other event or
condition is to cause, or to permit the holder or holders or beneficiary or

reason of a pending appeal or otherwise, shall not be in effect; or

domestic), or (vii) take any action under the laws of any jurisdiction (foreign
or domestic) analogous to any of the foregoing; or

          g. a proceeding or case shall be commenced in respect of the Borrower

     Section 3.2. Filings; Actions to Achieve Perfection. Fully executed Uniform
Commercial Code financing statements (including fixture filings, as applicable)
or other appropriate filings, recordings or registrations containing a
description of the Collateral have been delivered to the Secured Parties for
filing in each United States governmental, municipal or other office specified
in Schedule A, which are all the filings, recordings and registrations that are
necessary to publish notice of and protect the validity of and to establish a
legal, valid and perfected security interest in favor of the Secured Parties in
respect of all Collateral in which the Security Interest may be perfected by
filing, recording or registration in the United States (or any political
subdivision thereof) and its territories and possessions, and no further or
subsequent filing, refiling, recording, rerecording, registration or
reregistration is necessary in any such jurisdiction, except as provided under
applicable law with respect to the filing of continuation statements or with
respect to the filing of amendments or new filings to reflect the change of the
Grantor's name, location, identity or corporate structure. The Grantor's name is
listed in the preamble of this Agreement identically to how it appears on its
certificate of incorporation or other organizational documents.

     Section 3.3. Validity and Priority of Security Interest. The Security
Interest constitutes (a) a legal and valid security interest in all the
Collateral securing the payment and performance of the Obligations, (b) subject
only to the filings described in Section 3.2 above and other previously
perfected security interests in the Collateral listed on Schedule 3.3 to this
Agreement ("Existing Liens"), a perfected security interest in all Collateral in
which a security interest may be perfected by filing, recording or registration
in the United States pursuant to the Uniform Commercial Code or other applicable
law in the United States (or any political subdivision thereof) and its
territories and possessions or any other country, state or nation (or any
political subdivision thereof). The Security Interest is and shall be
subordinate to any other Existing Lien on any of the Collateral.

     Section 3.4. Absence of Other Liens. The Grantor's Collateral is owned by
the Grantor free and clear of any Lien other than Existing Liens. Without
limiting the foregoing and except as set forth on Schedule 3.4 to this
Agreement, the Grantor has not filed or consented to any filing described in
Schedule A in favor of any Person other than the Secured Parties, nor permitted
the granting or assignment of a security interest or permitted perfection of any
security interest in the Collateral in favor of any Person other than the
Secured Parties. The Grantor's

having possession of all instruments and cash constituting Collateral from time
to time and the filing of financing statements in the offices referred to in
Schedule A hereto results in the perfection of such security interest. Such
security interest is, or in the case of Collateral in which the Grantor obtain
rights after the date hereof, will be, a perfected, first priority security
interest. Such notices, filings and all other action necessary or desirable to
perfect and protect such security interest have been duly taken.

     Section 3.5. Valid and Binding Obligation. This Agreement constitutes the
legal, valid and binding obligation of the Grantor, enforceable against the
Grantor in accordance with its terms, except (i) as limited by applicable
bankruptcy, insolvency, reorganization, moratorium, and other laws of general
application affecting enforcement of creditors' rights generally, (ii) as
limited by laws relating to the availability of specific performance, injunctive
relief, or other equitable remedies, and (iii) to the extent the indemnification
provisions contained in this Agreement may be limited by applicable federal or
state securities laws.

                             ARTICLE IV. Covenants

     Section 4.1. Change of Name; Location of Collateral; Place of Business,
State of Formation or Organization.

          (a) The Grantor shall notify the Secured Parties in writing promptly
     of any change (i) in its corporate name or in any trade name used to
     identify it in the conduct of its business or in the ownership of its
     properties, (ii) in the location of its chief executive office, its
     principal place of business, any office in which it maintains books or
     records relating to Collateral owned by it (including the establishment of
     any such new office or facility), (iii) in its identity or corporate
     structure such that a filed filing made under the Uniform Commercial Code
     becomes misleading or (iv) in its Federal Taxpayer Identification Number.
     In extension of the foregoing, the Grantor shall not effect or permit any
     change referred to in the preceding sentence unless all filings have been
     made under the Uniform Commercial Code or otherwise that are required in
     order for the Secured Parties to continue at all times following such
     change to have a valid, legal and perfected first priority security
     interest in all the Collateral.

          (b) Without limiting Section 4.1(a), without the prior written consent
     of the Secured Parties in each instance, the Grantor shall not change its
     (i) principal residence, if it is an individual, (ii) place of business, if
     it has only one place of business and is not a Registered Organization,
     (iii) principal place of business, if it has more than one place of
     business and is not a Registered Organization, or (iv) state of
     incorporation, formation or organization, if it is a Registered
     Organization.

similar to those in which the Grantor is engaged, but in any event to include
complete accounting records indicating all payments and proceeds received with
respect to any part of the Collateral, and, at such time or times as the Secured
Parties may reasonably request, promptly to prepare and deliver to the Secured
Parties a duly certified schedule or

<PAGE>

                                                                               5

schedules in form and detail satisfactory to the Secured Parties showing the
identity, amount and location of any and all Collateral.

     Section 4.3. Periodic Certification; Notice of Changes. In the event there
should at any time be any change in the information represented and warranted
herein or in the documents and instruments executed and delivered in connection
herewith, the Grantor shall immediately notify the Secured Parties in writing of
such change (this notice requirement shall be in extension of and shall not
limit or relieve the Grantor of any other covenants hereunder).

     Section 4.4. Protection of Security. The Grantor shall, at its own cost and
expense, take any and all actions necessary to defend title to the Collateral
against all persons and to defend the Security Interest of the Secured Parties
in the Collateral and the priority thereof against any Lien.

     Section 4.5. Inspection and Verification. The Secured Parties and such
persons as the Secured Parties may reasonably designate shall have the right to
inspect the Collateral, all records related thereto (and to make extracts and
copies from such records) and the premises upon which any of the Collateral is
located, to discuss the Grantor's affairs with the officers of the Grantor and
its independent accountants and to verify under reasonable procedures the
validity, amount, quality, quantity, value, condition and status of, or any
other matter relating to, the Collateral, including, in the case of collateral
in the possession of any third Person, by contacting any account debtor or third
Person possessing such Collateral for the purpose of making such a verification.
Out-of-pocket expenses in connection with any inspections by representatives of
the Secured Parties shall be (a) the obligations of the Grantor with respect to
any inspection after the Secured Parties' demand payment of the Notes or (b) the
obligation of the Secured Parties in any other case.

     Section 4.6. Taxes; Encumbrances. At their option, the Secured Parties may
discharge, Liens other than Existing Liens at any time levied or placed on the
Collateral and may pay for the maintenance and preservation of the Collateral to
the extent the Grantor fails to do so and the Grantor shall reimburse the
Secured Parties on demand for any payment made or any expense incurred by the
Secured Parties pursuant to the foregoing authorization; provided, however, that
nothing in this Section shall be interpreted as excusing the Grantor from the
performance of, or imposing any obligation on the Secured Parties to cure or
perform, any covenants or other obligation of the Grantor with respect to any
Lien or maintenance or preservation of Collateral as set forth herein.

     Section 4.7. Use and Disposition of Collateral. The Grantor shall not make
or permit to be made an assignment, pledge or hypothecation of any Collateral or
shall grant any other Lien in respect of the Collateral without the prior
written consent of the Secured Parties. The Grantor shall not make or permit to
be made any transfer of any Collateral and the Grantor shall remain at all times
in possession of the Collateral owned by it, other than with respect to Existing
Liens and other liens approved by the Secured Parties.

     Section 4.8. Insurance/Notice of Loss. Within a reasonable period of time
following the date of this Agreement, Grantor, at its own expense, shall
maintain or cause to be maintained insurance covering physical loss or damage to
the Collateral. In extension of the foregoing and without limitation, such
insurance shall be payable to the Secured Parties as loss payee under a

<PAGE>

                                                                               6

"standard" loss payee clause, and the Secured Parties shall be listed as an
"additional insured" on Grantor's general liability insurance. Such insurance
shall not be terminated, cancelled or not renewed for any reason, including
non-payment of insurance premiums, unless the insurer shall have provided the
Secured Parties at least 30 days prior written notice. Grantor irrevocably
makes, constitutes and appoints the Secured Parties (and all officers, employees
or agents designated by the Secured Parties) as its true and lawful agent and
attorney-in-fact for the purpose, at any time following the Secured Parties'
demand for payment of the Notes, of making, settling and adjusting claims in
respect of Collateral under policies of insurance, endorsing the name of Grantor
on any check, draft, instrument or other item of payment for the proceeds of
such policies of insurance and for making all determinations and decisions with
respect thereto. In the event that Grantor at any time or times shall fail to
obtain or maintain any of the policies of insurance required hereby or to pay
any premium in whole or part relating thereto, the Secured Parties may, without
waiving or releasing any obligation or liability of Grantor hereunder, in their
sole discretion, obtain and maintain such policies of insurance and pay such
premium and take any other actions with respect thereto as the Secured Parties
deem advisable. All sums disbursed by the Secured Parties in connection and in
accordance with this Section, including reasonable attorneys' fees, court costs,
expenses and other charges relating thereto, shall be payable upon demand, by
Grantor to the Secured Parties and shall be additional Obligations secured
hereby. Grantor shall promptly notify the Secured Parties if any material
portion of the Collateral owned or held by Grantor is damaged or destroyed. The
proceeds of any casualty insurance in respect of any casualty loss of any of the
Collateral shall (i) so long as the Secured Parties have not demanded payment of
the Notes, be disbursed to Grantor for direct application by Grantor solely to
the repair or replacement of Grantor's property so damaged or destroyed, and
(ii) in all other circumstances, be held by the Secured Parties as cash
collateral for the Obligations. The Secured Parties may, at their sole option,
disburse from time to time all or any part of such proceeds so held as cash
collateral, upon such terms and conditions as the Secured Parties may reasonably
prescribe, for direct application by the Secured Parties solely to the repair or
replacement of Grantor's property so damaged or destroyed, or Grantor may apply
all or any part of such proceeds to the Obligations.

     Section 4.9. Legend. Grantor shall legend, in form and manner satisfactory
to the Secured Parties, its accounts and its books, records and documents
evidencing or pertaining thereto with an appropriate reference to the fact that
such accounts have been assigned to the Secured Parties and that the Secured
Parties have a security interest therein.

                ARTICLE V. Further Assurances; Power of Attorney

     Section 5.1. Further Assurances. Grantor shall, at its own expense,
execute, acknowledge, deliver and cause to be duly filed all such further
instruments and documents and take all such actions as the Secured Parties may
from time to time reasonably request to better assure, preserve, protect and
perfect the Security Interest and the rights and remedies created hereby,
including the payment of any fees and taxes required in connection with the
execution and delivery of this Agreement, the granting of the Security Interest
and the filing of any financing statements (including fixture filings) or other
documents in connection herewith or therewith. If any amount payable under or in
connection with any of the Collateral shall be or become evidenced by any
promissory note or other instrument, such note or instrument shall be
immediately pledged and delivered to the Secured Parties, duly endorsed in a
manner satisfactory to the Secured Parties.

     Section 5.2. Power of Attorney.

          (a) Grantor hereby irrevocably (as a power coupled with an interest)
constitutes and appoints the Secured Parties (and all officers, employees or
agents designated by the Secured Parties), its attorney-in-fact with full power
of substitution, for the benefit of the Secured Parties,

               (i) to take all appropriate action and to execute all documents
     and instruments that may be necessary or desirable to accomplish the
     purposes of this Agreement, and without limiting the generality of the
     foregoing, Grantor hereby grants the power to file one or more financing
     statements (including fixture filings), continuation statements, filings
     with the United States Patent and Trademark Office or United States
     Copyright Office (or any successor office or any similar office in any
     other country) or other documents for the purpose of perfecting,
     confirming, continuing, enforcing or protecting the Security Interest
     granted by Grantor, without the signature of Grantor, and naming Grantor as
     debtor and the Secured Parties as secured party; and

               (ii) at any time following the Secured Parties' demand for
     payment of the Notes (i) to receive, endorse, assign and/or deliver any and
     all notes, acceptances, checks, drafts, money orders or other evidences of
     payment relating to the Collateral or any part thereof; (ii) to demand,
     collect, receive payment of, give receipt for and give discharges and
     releases of all or any of the Collateral; (iii) to sign the name of Grantor
     on any invoice or bill of lading relating to any of the Collateral; (iv) to
     send verifications of accounts to any account debtor or any other Person
     liable for an account; (v) to commence and prosecute any and all suits,
     actions or proceedings at law or in equity in any court of competent
     jurisdiction to collect or otherwise realize on all or any of the
     Collateral or to enforce any rights in respect of any Collateral; (vi) to
     settle, compromise, compound, adjust or defend any actions, suits or
     proceeding relating to all or any of the Collateral; and (vii) to use,
     sell, assign, transfer, pledge, make any agreement with respect to or
     otherwise deal with all or any of the Collateral, and to do all other acts
     and things necessary to carry out the purposes of this Agreement, as fully
     and completely as though the Secured Parties were the absolute owner of the
     Collateral for all purposes; provided, however, that nothing herein
     contained shall be construed as requiring or obligating the Secured Parties
     to make any commitment or to make any inquiry as to the nature or
     sufficiency of any payment received by the Secured Parties, or to present
     or file any claim or notice, or to take any action with respect to the
     Collateral or any part thereof or the moneys due or to become due in
     respect thereof or any property covered thereby, and no action taken or
     omitted to be taken by the Secured Parties with respect to the Collateral
     or any part thereof shall give rise to any defense, counterclaim or offset
     in favor of Grantor or to any claim or action against the Secured Parties.

          (b) The provisions of this Article shall in no event relieve Grantor
of any of its obligations hereunder with respect to the Collateral or any part
thereof or impose any obligation on the Secured Parties to proceed in any
particular manner with respect to the Collateral or any part thereof, or in any
way limit the exercise by the Secured Parties of any other or further right
which it may have on the date of this Agreement or hereafter, whether hereunder,
by law or otherwise.

                                                                               8

                              ARTICLE VI. Remedies

     Section 6.1. Remedies upon Default.

          (a) Upon the occurrence and during the continuance of an Event of
     Default, Grantor agrees to deliver each item of its Collateral to the
     Secured Parties on demand, and it is agreed that the Secured Parties shall
     have the right to take any of or all the following actions at the same or
     different times (but at all times subject to any Existing Liens): with or
     without legal process and with or without prior notice or demand for
     performance, to take possession of the Collateral and without liability for
     trespass to enter any premises where the Collateral may be located for the
     purpose of taking possession of or removing the Collateral, exercise
     Grantor's right to bill and receive payment for completed work and,
     generally, to exercise any and all rights afforded to a secured party under
     the Uniform Commercial Code or other applicable law. Without limiting the
     generality of the foregoing, Grantor agrees that the Secured Parties shall
     have the right, subject to the mandatory requirements of applicable law, to
     sell or otherwise dispose of all or any part of the Collateral, at public
     or private sale or at any broker's board or on any securities exchange, for
     cash, upon credit or for future delivery as the Secured Parties shall deem
     appropriate. The Secured Parties shall be authorized at any such sale (if
     it deems it advisable to do so) to restrict the prospective bidders or
     purchasers to persons who will represent and agree that they are purchasing
     the Collateral for their own account for investment and not with a view to
     the distribution or sale thereof, and upon consummation of any such sale
     the Secured Parties shall have the right to assign, transfer and deliver to
     the purchaser or purchasers thereof the Collateral so sold. Each such
     purchaser at any such sale shall hold the property sold absolutely, free
     from any claim or right on the part of Grantor, and Grantor hereby waives
     (to the extent permitted by law) all rights of redemption, stay and
     appraisal which Grantor now has or may at any time in the future have under
     any rule of law or statute now existing or hereafter enacted.

          (b) The Secured Parties shall give Grantor ten (10) days' written
     notice (which Grantor agrees is reasonable notice within the meaning of
     Section 9-504(3) of the Uniform Commercial Code) of the Secured Parties'
     intention to make any sale of Collateral. Such notice, in the case of a
     public sale, shall state the time and place for such sale and, in the case
     of a sale at a broker's board or on a securities exchange, shall state the
     board or exchange at which such sale is to be made and the day on which the
     Collateral, or portion thereof, will first be offered for sale at such
     board or exchange. Any such public sale shall be held at such time or times
     within ordinary business hours and at such place or places as the Secured
     Parties may fix and state in the notice (if any) of such sale. At any such
     sale, the Collateral, or portion thereof, to be sold may be sold in one lot
     as an entirety or in separate parcels, as the Secured Parties may (in their
     sole and absolute discretion) determine. The Secured Parties shall not be
     obligated to make any sale of any Collateral if it shall determine not to
     do so, regardless of the fact that notice of sale of such Collateral shall
     have been given. The Secured Parties may, without notice or publication,
     adjourn any public or private sale or cause the same to be adjourned from
     time to time by announcement at the time and place fixed for sale, and such
     sale may, without further notice, be made at the time and place to which
     the same was so adjourned. In case any sale of all or any part of the
     Collateral is made on credit or for future delivery, the Collateral so sold
     may be retained by the Secured Parties until the

<PAGE>

                                                                               9

     sale price is paid by the purchaser or purchasers thereof, but the Secured
     Parties shall not incur any liability in case any such purchaser or
     purchasers shall fail to take up and pay for the Collateral so sold and, in
     case of any such failure, such Collateral may be sold again upon like
     notice. At any public (or, to the extent permitted by law, private) sale
     made pursuant to this Section, the Secured Parties may bid for or purchase,
     free (to the extent permitted by law) from any right of redemption, stay,
     valuation or appraisal on the part of Grantor (all said rights being also
     hereby waived and released to the extent permitted by law), the Collateral
     or any part thereof offered for sale and may make payment on account
     thereof by using any claim then due and payable to the Secured Parties from
     Grantor as a credit against the purchase price, and the Secured Parties
     may, upon compliance with the terms of sale, hold, retain and dispose of
     such property without further accountability to Grantor therefor. For
     purposes hereof, a written agreement to purchase the Collateral or any
     portion thereof shall be treated as a sale thereof; the Secured Parties
     shall be free to carry out such sale pursuant to such agreement and Grantor
     shall not be entitled to the return of the Collateral or any portion
     thereof subject thereto, notwithstanding the fact that after the Secured
     Parties shall have entered into such an agreement all Obligations have been
     paid in full. As an alternative to exercising the power of sale herein
     conferred upon it, the Secured Parties may proceed by a suit or suits at
     law or in equity to foreclose this Agreement and to sell the Collateral or
     any portion thereof pursuant to a judgment or decree of a court or courts
     having competent jurisdiction or pursuant to a proceeding by a
     court-appointed receiver.

     Section 6.2. Application of Proceeds. The Secured Parties shall apply the
proceeds of any collection or sale of the Collateral, as well as any Collateral
consisting of cash, as follows:

          (a) FIRST, to the payment of all costs and expenses incurred by the
Secured Parties in connection with such collection or sale or otherwise in
connection with this Agreement or any of the Obligations, including all court
costs and the fees and expenses of its agents and legal counsel, and any other
costs or expenses incurred in connection with the exercise of any right or
remedy hereunder, under the Letter Loan Agreement, the Notes and the other Loan
Documents;

          (b) SECOND, to the payment in full of the Obligations; and

          (c) THIRD, to Grantor, its successors or assigns, or to whomsoever may
be lawfully entitled to receive the same, or as a court of competent
jurisdiction may otherwise direct.

     Subject to the foregoing, the Secured Parties shall have absolute
discretion as to the time of application of such proceeds, moneys or balances in
accordance with this Agreement. Upon any sale of the Collateral by the Secured
Parties (including pursuant to a power of sale granted by statute or under a
judicial proceeding), the receipt of any such proceeds, moneys or balances by
the Secured Parties or of the officer making the sale shall be a sufficient
discharge to the purchaser or purchasers of the Collateral so sold and such
purchaser or purchasers shall not be obligated to see to the application of any
part of the purchase money paid over to the Secured Parties or such officer or
be answerable in any way for the misapplication thereof.

                                                                              10

     Section 6.3. Grant of License to Use Intellectual Property. For the purpose
of enabling the Secured Parties to exercise rights and remedies under this
Article at such time as the Secured Parties shall be lawfully entitled to
exercise such rights and remedies, Grantor hereby grants to the Secured Parties
an irrevocable, non-exclusive license (exercisable without payment of royalty or
other compensation to Grantor) to use, license or sub-license any of the
Collateral consisting of intellectual property now owned or hereafter acquired
by Grantor, and wherever the same may be located, and including in such license
reasonable access to all media in which any of the licensed items may be
recorded or stored and to all computer software and programs used for the
compilation or printout thereof. The use of such license by the Secured Parties
may be exercised, at the option of the Secured Parties, only following the
Secured Parties' demand for payment of the Notes.

                           ARTICLE VII. Miscellaneous

     Section 7.1. Notices. All communications and notices hereunder to the
Grantor and to the Secured Parties shall (except as otherwise expressly
permitted herein) be in writing and delivered to the Grantor or the Secured
Parties, as the case may be, as provided in the Letter Loan Agreement.

     Section 7.2. Security Interest Absolute. All rights of the Secured Parties
hereunder, the Security Interest and all obligations of Grantor hereunder shall
be absolute and unconditional irrespective of (a) any lack of validity or
enforceability of the Letter Loan Agreement, the Notes, any Loan Document or any
agreement with respect to any of the Obligations or any other agreement or
instrument relating to any of the foregoing, (b) any change in the time, manner
or place of payment of, or in any other term of, all or any of the Obligations,
or any other amendment or waiver of or any consent to any departure from the
Letter Loan Agreement, the Notes, any Loan Document or any other agreement or
instrument, (c) any exchange, release or non-perfection of any Lien on other
collateral, or any release or amendment or waiver of or consent under or
departure from any guarantee, securing or guaranteeing all or any of the
Obligations, or (d) any other circumstance that might otherwise constitute a
defense available to, or a discharge of, Grantor in respect of the Obligations
or this Agreement.

     Section 7.3. Survival of Agreement. All covenants, agreements,
representations and warranties made by Grantor herein and in the certificates or
other instruments prepared or delivered in connection with or pursuant to this
Agreement shall be considered to have been relied upon by the Secured Parties
and shall survive the making of the loan and the execution and delivery to the
Secured Parties of the Notes, regardless of any investigation made by the
Secured Parties or on their behalf; and shall continue in full force and effect
until this Agreement shall terminate.

     Section 7.4. Binding Effect; Several Agreement; Successors and Assigns.
This Agreement shall become effective as to Grantor when a counterpart hereof
executed on behalf of Grantor shall have been delivered to the Secured Parties
and a counterpart hereof shall have been executed on behalf of the Secured
Parties, and thereafter shall be binding upon Grantor and the Secured Parties
and their respective successors and assigns, and shall inure to the benefit of
Grantor, the Secured Parties and their respective successors and assigns, except
that Grantor shall not have the right to assign or transfer its rights or
obligations hereunder or any interest herein or in the Collateral (and any such
assignment or transfer shall be void) except as expressly

<PAGE>

                                                                              11

contemplated by this Agreement, the Letter Loan Agreement, the Notes or the
other Loan Documents.

     Section 7.5. Secured Parties' Fees and Expense; Indemnification.

          (a) Grantor agrees to pay upon demand to the Secured Parties the
     amount of any and all reasonable expenses, including all reasonable fees,
     disbursements and other charges of its counsel and of any experts or
     agents, which the Secured Parties may incur in connection with (i) the
     administration of this Agreement (including the customary fees and charges
     of the Secured Parties for any audits conducted by them or on their behalf
     with respect to the accounts inventory), (ii) the custody or preservation
     of, or the sale of, collection from or other realization upon any of the
     Collateral, (iii) the exercise, enforcement or protection of any of the

          (b) Grantor agrees to indemnify the Secured Parties and the agent,
     contractors and employees of the Secured Parties (collectively, the
     "Indemnitees") against, and hold each of them harmless from, any and all
     losses, claims, damages, liabilities and related expenses, including
     reasonable fees, disbursements and other charges of counsel, incurred by or
     asserted against any of them arising out of, in any way connected with, or
     as a result of, the execution, delivery, or performance of this Agreement
     or any agreement or instrument contemplated hereby or any claim,
     litigation, investigation or proceeding relating hereto or to the
     Collateral, whether or not any Indemnitee is a party thereto; provided that
     such indemnity shall not, as to any Indemnitee, be available to the extent
     that such losses, claims, damages, liabilities or related expenses are
     determined by a court of competent jurisdiction by final and nonappealable
     judgment to have resulted from the gross negligence or willful misconduct
     of such Indemnitee.

          (c) Any such amounts payable as provided hereunder shall be additional
     Obligations secured hereby. The provisions of this Section shall remain
     operative and in full force and effect regardless of the termination of
     this Agreement, the Letter Loan Agreement, the Notes or the other Loan
     Documents, the consummation of the transactions contemplated hereby, the
     repayment of any of the Obligations, the invalidity or unenforceability of
     any term or provision of this Agreement, the Letter Loan Agreement, the
     Notes or the other Loan Documents, or any investigation made by or on
     behalf of the Secured Parties. All amounts due under this Section shall be
     payable on written demand therefor.

     Section 7.6. GOVERNING LAW. THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE
WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK.

     Section 7.7. Waivers; Amendment.

          (a) No failure or delay of the Secured Parties in exercising any power
or right hereunder shall operate as a waiver thereof, nor shall any single or
partial exercise of any such right or power, or any abandonment or
discontinuance of steps to enforce such a right or power,

<PAGE>

                                                                              12

preclude any other or further exercise thereof or the exercise of any other
right or power. The rights and remedies of the Secured Parties hereunder and
under the Letter Loan Agreement are cumulative and are not exclusive of any
rights or remedies that they would otherwise have. No waiver of any provisions
of this Agreement, the Letter Loan Agreement, the Notes or the other Loan
Documents or consent to any departure by Grantor therefrom shall in any event be
effective unless the same shall be permitted by paragraph (b) below, and then
such waiver or consent shall be effective only in the specific instance and for
the purpose for which given. No notice to or demand on Grantor in any case shall
entitle Grantor to any other or further notice or demand in similar or other
circumstances.

          (b) Neither this Agreement nor any provision hereof may be waived,
amended or modified except pursuant to an agreement or agreements, in writing
entered into by the Secured Parties and Grantor.

     Section 7.8. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO THE
FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY
JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER
OR IN CONNECTION WITH THIS AGREEMENT, THE LETTER LOAN AGREEMENT OR THE NOTES.
EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY
OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD
NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B)
ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER
INTO THIS AGREEMENT, THE LETTER LOAN AGREEMENT AND THE NOTES, AS APPLICABLE, BY,
AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

     Section 7.9. Severability. In the event any one or more of the provisions
contained in this Agreement should be held invalid, illegal or unenforceable in
any respect, the validity, legality and enforceability of the remaining
provisions contained herein shall not in any way be affected or impaired thereby
(it being understood that the invalidity of a particular provision in a
particular jurisdiction shall not in and of itself affect the validity of such
provision in any other jurisdiction). The parties shall endeavor in good-faith
negotiations to replace the invalid, illegal or unenforceable provisions with
valid provisions the economic effect of which comes as close as possible to that
of the invalid, illegal or unenforceable provisions.

     Section 7.10. Counterparts. This Agreement may be executed in two or more
counterparts, each of which shall constitute an original but all of which when
taken together shall constitute but one contract. Each party shall be entitled
to rely on a facsimile signature of any other party hereunder as if it were an
original.

     Section 7.11. Jurisdiction; Consent to Service of Process.

          (a) Grantor hereby irrevocably and unconditionally submits, for itself
     and its property, to the nonexclusive jurisdiction of any New York State
     court or Federal court of the United States of America sitting in New York
     City, and any appellate court from any thereof, in any action or proceeding
     arising out of or relating to this Agreement, the Letter Loan Agreement or
     the Notes, or for recognition or enforcement of any judgment,

<PAGE>

                                                                              13

     and each of the parties hereto hereby irrevocably and unconditionally
     agrees that all claims in respect of any such action or proceeding may be
     heard and determined in such New York State or, to the extent permitted by
     law, in such Federal court. Each of the parties hereto agrees that a final
     judgment in any such action or proceeding shall be conclusive and may be
     enforced in other jurisdictions by suit on the judgment or in any other
     manner provided by law. Nothing in this Agreement shall affect any right
     that the Secured Parties may otherwise have to bring any action or
     proceeding relating to this Agreement, the Letter Loan Agreement, the Notes
     or the other Loan Documents against Grantor or its properties in the courts
     of any jurisdiction.

          (b) Grantor hereby irrevocably and unconditionally waives, to the
     fullest extent it may legally and effectively do so, any objection which it
     may now or hereafter have to the laying of venue of any suit, action or
     proceeding arising out of or relating to this Agreement, the Letter Loan
     Agreement, the Notes or the other Loan Documents in any New York State or
     Federal court. Each of the parties hereto hereby irrevocably waives, to the
     fullest extent permitted by law, the defense of an inconvenient forum to
     the maintenance of such action or proceeding in any such court.

          (c) Each party to this Agreement irrevocably consents to service of
     process in the manner provided for notices in Section 7.1. Nothing in this
     Agreement will affect the right of any party to this Agreement to process
     in any other manner permitted by law.

     Section 7.12. Termination. This Agreement and the Security Interest shall
terminate when all the Obligations have been paid in full, at which time the
Secured Parties shall execute and deliver to Grantor, at Grantor's expense, all
Uniform Commercial Code termination statements and similar documents which
Grantor shall reasonably request to evidence such termination. Any execution and
delivery of termination statements or documents pursuant to this Section shall
be without recourse to or warranty by the Secured Parties.

     Section 7.13. Prejudgment Remedy Waiver. Grantor acknowledges that this
Agreement, the Letter Loan Agreement, the Notes and the other Loan Documents
evidence a commercial transaction and that it could, under certain circumstances
have the right, to notice of and hearing on the right of the Secured Parties to
obtain a prejudgment remedy, such as attachment, garnishment and/or replevin,
upon commencing any litigation against Grantor. Notwithstanding, Grantor hereby
waives all rights to notice, judicial hearing or prior court order to which it
might otherwise have the right under any state or federal statute or
constitution in connection with the obtaining by the Secured Parties of any
prejudgment remedy by reason of this Agreement, the Letter Loan Agreement, the
Notes, the other Loan Documents or by reason of the Obligations or any renewals
or extensions of the same. Grantor also waives any and all objection which it
might otherwise assert, now or in the future, to the exercise or use by the
Secured Parties of any right of setoff, repossession or self help as may
presently exist under statute or common law.
