Gentlemen:

Upon your written acceptance, to be noted at the foot of this Agreement, the
following will state the terms and conditions under which you are to act as our
sole factor:

     1. APPOINTMENT AND SALE OF ACCOUNTS: We hereby appoint you our sole factor,
and hereby sell and assign to you, making you absolute owner thereof, all of our
accounts due from Ecogard, Inc. and such other accounts as you may agree to
purchase from us from time to time, contract rights, notes, bills, acceptances
and all other obligations to us (hereinafter referred to as "Receivables") for
the payment of money, in cash or in kind, together with all proceeds thereof,
all security and guarantees therefor, and all of our rights to the goods and
property represented thereby. You shall have all the rights of an unpaid seller
or provider of the goods or services, the sale or rendering of which gives rise
to each Receivable, including the rights of stoppage in transit, reclamation and
replevin. Upon each sale of goods or rendering of services, we shall execute and
deliver to you such confirmatory assignments of our Receivables as you may
require, in form and manner satisfactory to you, together with copies of
invoices, all shipping or delivery receipts, and such other proof of sale and
delivery or performance as you may, at any time or from time to time, require to
effect collection of our Receivables. We shall make appropriate notations upon
our books and records indicating the sale and assignment of our Receivables to
you. All invoices or other statements to our customers concerning Receivables
shall clearly state, in language satisfactory to you, that each such Receivable
has been sold and assigned to you and is payable to you and to you only. Copies
of Receivables sold and assigned to you shall also bear this language. During
the term of this Agreement, we agree not to sell, negotiate, pledge, assign or
grant any security interest in any or all of our Receivables to anyone other
than you. If we are or become engaged in finishing or improving goods, we agree,
notwithstanding any credit approval you may have given on the customer(s)
involved, to assert promptly, at our expense and upon your demand, any lien
rights provided by law on goods in our possession. We will remit to you the
proceeds of sale of such goods to satisfy the amounts owed to you by the owner
of the goods. It is understood that your credit approval is limited to the net
amount of the customer's obligation after the sale and disposition of such
goods.

     2. ADDITIONAL COLLATERAL: In addition to Receivables and all proceeds
thereof, we also assign to you all right, title and interest, and grant to you a
security interest in, the following collateral to secure all of our present and
future obligations and indebtedness to you: (1) all deposit, savings, passbook
or like accounts maintained at any bank, savings and loan or similar
institution; and (2) the proceeds of any tax refund due or to become due to us
by the state or federal government.

     3. CREDIT RISK: You will assume the credit risk only on Receivables for
which you have given credit approval in writing ("Credit Approvals"). In the
absence of such written Credit Approval from you, the Receivable is at our risk.
If we ship merchandise or provide services based on a verbal approval, we
acknowledge our responsibility to ensure that such approval is received by us in
writing in a timely manner. We acknowledge that Credit Approvals may be
withdrawn, either orally or in writing, in your discretion at any time if, in
your opinion, a customer's credit standing becomes impaired before actual
delivery of merchandise or rendering of services. Credit Approvals shall be
limited to the specific terms and amounts indicated, and, notwithstanding any
information subsequently provided to us by you, such credit approvals are
automatically rescinded and withdrawn if the terms of sale vary from the terms
approved by you, or if the terms of sale are changed by us


<PAGE>

                                  Page 2 of 9


without your written Credit Approval on the new terms, or if the Receivable is
not assigned to you promptly (within five days) after creation. We further
acknowledge that if we ship merchandise or provide services to a customer who
has outstanding Receivables from us, and such customer's credit line and/or
outstanding Credit Approvals have been withdrawn by you, and the Receivables
created thereby, whether or not they are sold and assigned to you, exceed ten
percent (10%) of the amount outstanding on your books, that any credit approvals
applying to those Receivables outstanding on your books are cancelled and all
outstanding Receivables from that customer are at our risk. If a customer, after
receiving and accepting delivery of goods or services (subject to all warranties
herein) for which you have given written Credit Approval, fails to pay a
Receivable when due, and such nonpayment is due solely to financial inability to
pay, you shall bear any loss thereon. If nonpayment is due to any other reason,
however, you shall not be responsible. Specifically, you shall not be
responsible for any nonpayment of a Receivable: (a) because of the assertion of
any claim or dispute by a customer for any reason whatsoever, including, without
limitation, disputes as to price, terms of sale, delivery, quantity, quality, or
other, or the exercise of any counterclaim or offset (whether or not such claim,
counterclaim or offset relates to the specific Receivable); (b) where nonpayment
is a consequence of enemy attack, civil commotion, strikes, lockouts, the act or
restraint of public authorities, acts of God or force majeure; or (c) if any
representation or warranty made by us to you in respect of such Receivable has
been breached. The assertion of a dispute by a customer shall have the effect of
negating any Credit Approval on the affected Receivable(s) and such
Receivable(s) shall be at our risk until paid or otherwise cleared from your
books. With regard to sales without Credit Approval or in excess of any Credit
Approval as to any given customer, we agree that any payments or credits
applying to any Receivables owing by such customer will be applied: FIRST, to
any Credit-Approved Receivables outstanding on your books; second, to any Client
Risk Receivables outstanding on your books; and, THIRD, to any Receivables
outstanding on our books. This order of payment applies regardless of the
respective dates the sales occurred and regardless of any notations on payment
items. If you fail to collect a Receivable for which you have given Credit
Approval within 120 days of its maturity, and your failure to collect such
Receivable is due solely to the customer's financial inability to pay, you shall
pay to us the net amount of such Receivable then owing on the Wednesday next
following the week during which said 120 days expired. Any Receivable for
freight, samples, or miscellaneous sales (including, without limitation, the
sale of merchandise and/or in quantities not regularly sold by us) is always
assigned to you at our risk, notwithstanding any written credit approval from
you. You shall have no liability of any kind for declining or refusing to give,
or for withdrawing, revoking, or modifying, any Credit Approval pursuant to the
terms of this Agreement, or for exercising or failing to exercise any rights or
remedies you may have under this Agreement or otherwise. In the event you
decline to give your Credit Approval on any order received by us from a
customer, and in advising us of such decline you furnish us with information as
to the credit standing of the customer, such information shall be deemed to have
been requested of you by us and your advice containing such information is
recognized as a privileged communication. We agree that such information shall
not be given to our customer or to our salesman. If necessary, we shall merely
advise our customer that credit has been declined on the account and that any
questions should be directed to you.

     4. CLIENT RISK RECEIVABLES: Any sale of goods or rendering of services by
us for which we have not received written Credit Approval, or for which Credit
Approval has been withdrawn or revoked, shall be known as a "Client Risk
Receivable." Any Client Risk Receivable(s) assigned to and purchased by you are
with recourse to us and at our sole credit risk. You shall have the right to
charge back to our account the amount of such Client Risk Receivable(s) at any
time and from time to time, either before or after maturity. We agree to pay you
on demand the full amount thereof, and, failing to do so, we agree to pay all
expenses incurred by you up to the date of such payment in attempting to collect
or enforce payment of such Receivable(s). However, in no event shall you have
any credit risk on the first $ 0 of any Receivable, notwithstanding the fact
that such Receivable has been credit approved by you. For purposes of
determining your credit risk hereunder, the Receivable balance due you from any
given customer shall be calculated as the aggregate amount owed by that customer
less any credits to which such customer may be entitled, and is not to be
construed to mean individual invoices owed by that customer.

     5.  PURCHASE PRICE:

           (a) The purchase price you shall pay to us for each Receivable shall
equal the Net Invoice Amount thereof less your factoring commission, as
specified below. As used herein, the term "Net Invoice Amount" means the gross
invoice amount of the Receivable, less returns (whenever made), all selling
discounts (at your option calculated on shortest terms) made available or
extended to our customer, whether taken or not, and credits or deductions of any
kind allowed or granted to or taken by the customer at any time. Unless
specifically shown on the invoice sold and assigned to you, no discount, credit,
allowance, or deduction with respect to any Receivable shall be granted, or
approved, by us to any customer without your prior written consent.


<PAGE>

                                  Page 3 of 9


           (b) The purchase price (as computed above), less (i) any reasonable
reserves or credit balance that you, in your sole discretion, determine to hold,
(ii) monies remitted, paid, or otherwise advanced by you to us or for our
account (including any amounts which you may be obligated to pay in the future),
and (iii) any other charges to our account provided for by this Agreement, shall
be payable by you to us on the date of collection. Monies shall be deemed to
have been collected on the date of receipt thereof by you plus THREE (3)
business days for clearing.

           (c) You shall be entitled to withhold a reserve of sums otherwise due
us, and may revise the amount of such reserve at any time and from time to time
if you deem it necessary to do so in order to protect your interests.
Furthermore, at your request, we shall maintain a credit balance ("credit
balance" or "reserve" shall be defined for purposes of this subparagraph 5(c) as
credit for amounts due us and not a "cash balance") with you in such amount as
you determine to be commensurate with the volume and character of the business
conducted by us and sufficient to protect you against all possible returns,
claims of our customers, indebtedness owing by us to you, or any other
contingencies. We shall pay you any debit balance in our account on demand.

           (d) In your sole discretion, in accordance with the terms of this
Agreement, you may from time to time advance to us, against the purchase price
of Receivables purchased by you hereunder, sums up to SEVENTY PERCENT (70%) of
the aggregate purchase price of Receivables outstanding at the time any such
advance is made, less: (1) Any such Receivables that are in dispute; (2) Any
such Receivables that are not credit approved; and (3) Any fees, actual or
estimated, that are chargeable to our reserve account. Unless otherwise
specified in any promissory note, or loan or other agreement, executed in
connection with such advance, any such advance shall be payable on demand and
shall bear interest at the rate set forth in subparagraph (e) below from the
date such advance is made until the date you would otherwise be obligated
hereunder to pay the purchase price of the Receivable(s) against which such
advance was made.

           (e) Interest upon the daily net balance of any monies remitted, paid,
advanced or otherwise charged to us or for our account before the payment date
(including any advance made pursuant to subparagraph 5(d) above), and interest
applicable to the charges or to the expenses referred to in this Agreement,
shall be charged to our reserve account as of the last day of each month at a
rate the greater of nine percent (9%) per anum or ONE PERCENT (1%) above the
Prime Rate. The Prime Rate shall mean, at any time, the rate of interest quoted
in the Wall Street Journal, Money Rates Section as the "Prime Rate" (currently
defined as the base rate on corporate loans posted by at least 75% of the
nation's thirty (30) largest banks). In the event that the Wall Street Journal
quotes more than one rate, or a range of rates as the Prime Rate, then the Prime
Rate shall mean the highest of the quoted rates. In the event that the Wall
Street Journal ceases to publish a Prime Rate, then the Prime Rate shall be the
average of the three largest U.S. money center commercial banks, as determined
by Capital Factors, Inc. If, during any month, our reserve account or credit
balance, subject to the terms and conditions of this Agreement, shall be in a
net credit balance (i.e., the reserve or credit balance exceeds outstanding
Receivables), then you agree to credit our reserve account as of the last day of
each month with interest at a rate equal to THREE PERCENT (3%) below the Prime
Rate. All such interest, whether charged or credited to our reserve account,
shall be computed for the actual number of days elapsed on the basis of year
consisting of 360 days. Any adjustment in your interest rate, whether downward
or upward, will become effective on the first day of the month following the
month in which the prime rate of interest is reduced or increased. HOWEVER, in
no event shall the rate of interest agreed to or charged to us hereunder exceed
the maximum rate of interest permitted to be agreed to or charged to us under
applicable law. IT IS THE INTENTION OF THE PARTIES HERETO NOT TO MAKE ANY
AGREEMENT VIOLATIVE OF THE LAWS OF THE STATE OF FLORIDA OR THE UNITED STATES
RELATING TO USURY. IN NO EVENT, THEREFORE, SHALL ANY INTEREST DUE HEREUNDER BE
AT A RATE IN EXCESS OF THE HIGHEST LAWFUL RATE, i.e., IN NO EVENT SHALL YOU
CHARGE OR SHALL WE BE REQUIRED TO PAY ANY INTEREST THAT, TOGETHER WITH ANY OTHER
CHARGES HEREUNDER THAT MAY BE DEEMED TO BE IN THE NATURE OF INTEREST, HOWEVER
COMPUTED, EXCEEDS THE MAXIMUM LAWFUL RATE OF INTEREST ALLOWABLE UNDER THE LAWS
OF THE STATE OF FLORIDA AND/OR OF THE UNITED STATES. SHOULD ANY PROVISION OF
THIS AGREEMENT OR ANY OTHER AGREEMENT BETWEEN US BE CONSTRUED TO REQUIRE THE
PAYMENT OF INTEREST THAT EXCEEDS SUCH MAXIMUM LAWFUL RATE, ANY SUCH EXCESS SHALL
BE AND IS EXPRESSLY HEREBY WAIVED BY YOU. SHOULD ANY EXCESS INTEREST IN FACT BE
PAID, SUCH EXCESS SHALL BE DEEMED TO BE A PAYMENT OF THE PRINCIPAL AMOUNT OF
OUTSTANDING INDEBTEDNESS OWING BY US TO YOU AND SHALL BE APPLIED TO SUCH
PRINCIPAL.

     6.  FACTORING COMMISSIONS.

<PAGE>

                                  Page 4 of 9


           (a) For your services hereunder, we shall pay and you shall be
entitled to receive a factoring commission equal to ONE-HALF PERCENT (.5%) of
the gross Invoice Amount of each Receivable, which commission shall be due and
payable to you on the date such Receivable arises. Factoring commissions shall
be chargeable to our account with you. You shall be entitled to receive a
surcharge equal to ONE PERCENT (1%) of the gross Invoice Amount of all
Receivables arising out of our sales to Debtors-In-Possession. The minimum
factoring commission on each invoice or credit memo shall be $0.

           (b) Your commission, specified in paragraph 6(a) above, is based upon
our maximum selling terms of NINETY (90) days, and no more extended terms or
additional dating will be granted by us to any customer without your prior
written approval. If and when such extended terms or additional dating are given
to our customers, your commission with respect to the Receivables represented
thereby shall be increased by twenty-five percent (25%) for each 30 days, or
portion thereof, of extended or additional dating.

           (c) The minimum aggregate factoring commissions payable under this
Agreement for each contract period hereof shall be TWELVE THOUSAND DOLLARS
($12,000.00), which shall be payable at the rate of TWO THOUSAND DOLLARS
($2,000.00) per month. To the extent of any deficiency (after giving effect to
commissions payable under the foregoing subparagraphs), the difference between
the minimum and the amount already charged shall be chargeable to our account
with you.

     7. STATEMENT OF ACCOUNT: Once each month you shall render a statement
(Client Ledger) to us with respect to the Receivables purchased by you during
the previous month, any advances made by you, collections received by you, and
charges made to our account under this Agreement. Our account shall be charged
with all discounts (at your option, calculated on shortest terms) made available
to customers on assigned Receivables, all returns, allowances, deductions and
credits, and your reasonable expenses, including, without limitation, postage on
invoices, bank wire fees, filing fees, UCC search and similar charges. We will
also be charged with interest at the rate specified in paragraph 5(e) above,
with respect both to Receivables as to which a credit is issued after the
payment date applicable thereto, and any Receivables collected or charged back
after such credit, or to the date of collection or chargeback, as the case may
be. A discount, credit or allowance after issuance or granting may be claimed
solely by the customer. Each statement, report, or accounting rendered or issued
by you to us shall be deemed accepted by us and shall be conclusive and binding
upon us, unless within thirty (30) days after the date thereof we notify you to
the contrary by registered or certified mail, setting forth with specificity the
reasons why we believe such statement, report, or accounting is incorrect and
what we believe to be the correct amount thereof. Moreover, if we fail to
receive a monthly statement, we shall likewise be obligated to notify you in the
same manner as if we fail to accept the statement, and our failure to do so
shall relieve you of any responsibility or liability arising out of our not
receiving such monthly statement.

     8. REPRESENTATIONS AND WARRANTIES: We hereby represent and warrant to you
that: (i) each Receivable is a bona fide existing obligation created by a
customer's express order for, and the actual sale and physical delivery of, or
legal passage of title to, goods or the rendering of services to customers in
the ordinary course of business, which goods, prior to sale, we owned free and
clear of any liens or encumbrances, and which Receivable is then unconditionally
owing to us without dispute, defense, offset, or counterclaim; (ii) the
customers, which are not affiliated with us, have received and have accepted the
goods or services, and the invoices therefor, without dispute, offset, or claim
of any kind as to price, terms, quality, quantity, delay in shipment, offsets,
counterclaims, contra accounts or any other defense of any other kind and
character; (iii) the Receivables will not be subject to discounts, deductions,
allowances, offsets, counterclaims or other contra items, nor to any other
special terms of payment that are not shown on the face of the invoice thereof;
(iv) the Receivables will not represent delivery of merchandise upon
"consignment," "guaranteed sale," "sale or return," "payment on reorder," or
similar terms; and (v) the Receivables will not represent "pack, bill and hold"
transactions unless we have furnished you with a copy of our customer's purchase
order soon after its receipt, and you have obtained such customer's agreement to
grant you a security interest in the merchandise and pay for such merchandise at
maturity of our invoice irrespective of whether or not we have received
instructions to deliver the same; (vi) we are solvent; (vii) we have full right
and authority to sell or assign to you, and to grant to you a security interest
in, our Receivables; (viii) we have not granted and will not hereafter grant to
any other person a security interest in, or grant to any other person any right
to purchase, our Receivables, or, without your prior written consent, grant to
any other person a security interest in any of our inventory at any time during
the term of this Agreement and until all security interests or purchases granted
hereunder have been terminated; (ix) we have paid all taxes which have become
due and payable and there are no judgements, assessments, or liens filed against
us or any of our property, real or personal.

                                  Page 5 of 9


      9. SECURITY: As collateral security for any and all of our (and our
parent's subsidiaries' and affiliates') indebtedness and obligations to you (and
to your parent, subsidiaries and affiliates), whether matured or unmatured,
absolute or contingent, now existing or hereafter arising (including under
indemnity or reimbursement agreements or by subrogation), and however acquired
by you, whether arising directly between us or acquired by you by assignment,
whether relating to this Agreement or independent hereof, including all
obligations incurred by us to any other person factored or financed by you
(collectively, the "Obligations"), we do hereby grant to you a security interest
in all of our accounts, contract rights, computer software, programs, stored
data, aging schedules, customer lists, and general intangibles and any of the
royalties and other fees which become due for the use of any patents,
trademarks, or copyrights, whether or not otherwise specifically assigned to you
in this Agreement, now existing or hereafter acquired, and in the proceeds and
products thereof, any security and guarantees therefor, in the goods and
property represented thereby, in all of our books and records relating to the
forgoing, and in all reserves, credit balances, sums of money at any time to our
credit with you, and any of our property at any time in your possession. We
hereby irrevocably authorize and direct you to charge at any time to our account
any Obligations, and to pay any Obligations owing by us to your parent,
subsidiaries or affiliates, by so charging our account. We agree to execute
financing statements and any and all other instruments and documents that may
now or hereafter be provided for by the Uniform Commercial Code or other law
applicable thereto reflecting security interests granted to you hereunder. We
hereby appoint you as our attorney-in-fact and authorize you to sign such
financing statements on our behalf as debtor or to file such financing
statements without our signature, signed only by you as secured party. We shall
be liable for, and you may charge our account with, all reasonable costs and
expenses of filing such financing statements (including any filing or recording
taxes), making lien searches, and any attorney's fees and expenses that may be
incurred by you in perfecting, protecting, preserving, or enforcing your
security interests and rights hereunder.

      10. TERM: This Agreement shall continue in full force and effect for a
period of SIX (6) MONTHS from the date hereof and shall be deemed renewed from
year to year thereafter unless we give you notice in writing, by registered or
certified mail, not less than thirty (30) and not more than sixty (60) days
prior to the expiration of the original term of this Agreement (or any renewal
term thereof), of our intention to terminate this Agreement as of the end of
such term. You may terminate this Agreement at any time upon thirty (30) days
prior written notice to us. Further, termination of the Agreement shall not
serve to terminate the separate License Agreement between the parties.
Notwithstanding the foregoing, if we become insolvent or unable to meet our
debts as they mature, fail, close, suspend, or go out of business, commit an act
of bankruptcy, file or become the subject of a petition under the Bankruptcy Act
or law permitting the appointment of a receiver, liquidator, conservator, or
similar functionary, breach or become in default under this Agreement or any
other agreement with you (or your parent, subsidiaries or affiliates), or any
Obligation to you, or if there is a material change (by death or otherwise) in
our principal stockholders or owners as a result of their sale or transfer of
shares of capital stock, then, notwithstanding the foregoing, you shall have the
right to terminate this Agreement at any time without notice; provided, however,
that nothing contained in the foregoing shall prevent Mansur Industries issuance
and sale of common stock or preferred stock or other securities convertible into
common stock or require Mansur Industries to obtain consent of Capital Factors
in connection with Mansur Industries' issuance and sale of common stock or
preferred stock or other securities convertible into common stock. In the event
you elect to terminate this Agreement, and your decision to do so is a result of
a breach of this Agreement by us, then, notwithstanding any other provisions
contained herein, you shall be entitled to charge our account, and we agree to
pay to you, the monthly minimum factoring fee specified in paragraph 6(c) herein
for the later of ninety (90) days from the effective date of termination or
until any and all of our indebtedness to you pursuant to this Agreement shall
have been paid in full. Your rights and our Obligations arising out of
transactions having their inception prior to the termination date shall not be
affected by any termination or notice thereof. Termination of this Agreement
shall not terminate, extinguish, or remove any liens or security interests
granted to you hereunder until we have fully paid and discharged any and all of
our Obligations to you, and we shall continue to furnish to you confirmatory
assignments and schedules of Receivables previously assigned to you and all
proceeds in respect thereof. After the giving of any notice of termination
hereunder, and until the full liquidation of our account, we shall not be
entitled to receive any payments from you. From and after the effective date of
termination, all amounts charged or chargeable to our account hereunder, and all
our Obligations to you, shall become immediately due and payable without further
notice or demand.


      11.  MISCELLANEOUS:

           (a) Any goods rejected or returned by any customer shall be your
property held by us in trust for you separate and apart from any other goods,
and, upon your demand and in accordance
<PAGE>

                                  Page 6 of 9


with your instructions, shall forthwith be delivered to you or disposed of by us
without charge to you, with the proceeds of such disposition to be remitted
promptly to you. We shall promptly report to you, in writing, all disputes and
claims made by our customers, the refusal of any services, and the rejection or
return of or offer to return any goods, and we will promptly and diligently
prosecute, defend or settle all such claims and disputes at our expense. WE
AGREE TO PREPARE AND ASSIGN TO YOU ALL CREDIT MEMOS TO WHICH OUR CUSTOMERS HAVE
BECOME ENTITLED SINCE THE DATE OF OUR LAST ASSIGNMENT, and our failure to do so
entitles you to charge our account with any expenses incurred by you as a
result. As absolute owner of each Receivable, you may, in your sole discretion,
enforce, effect any compromise regarding settlement, or adjust any Receivable,
in your name or ours, without affecting or limiting our obligations to you under
this Agreement, whether or not any such Receivable shall have been charged back
to us. You reserve the right at any time to charge back to our account the full
amount of the Receivable(s) involved in any claim, dispute, rejection, or return
asserted or made by our customers, and we agree to pay you upon demand the full
amount thereof. The chargeback to our account of the amount of any such
Receivable shall not be deemed a reassignment to us, and title thereto and to
the proceeds thereof, all security and guarantees therefor, and our interest in
the goods represented thereby shall remain in you. We shall indemnify you for,
and hold you harmless against, any loss, liability, claim or expense of any kind
arising from any claims of, or disputes with, our customers as to terms, price,
quality, quantity, or otherwise, relating to any Receivable, including any claim
for return or reimbursement of any payments therefor. We agree to notify you
promptly when a customer asserts a dispute or claim of any kind, and upon your
notice to us of a customer dispute or claim, we agree to contact the customer
promptly to effect a resolution of such dispute or claim.

           (b) If any check, draft, note, acceptance, cash collection or payment
in any form is received by us on any Receivable, WE SHALL IMMEDIATELY TRANSMIT
AND DELIVER IT TO YOU IN THE FORM RECEIVED, and our failure to do so entitles
you to charge our account with any expenses incurred by you as a result. Until
our delivery of each such payment to you, it shall be held by us in trust for
you. We agree that you, and any such person or entity as you may from time to
time designate, shall have the right to sign and/or endorse our name on all
remittances and all papers, bills of lading, receipts, instruments and documents
relating to the Receivables and the transactions between us. You shall have the
right to deposit any checks or other remittances received on Receivables
regardless of notations or conditions placed thereon by our customers or
deductions reflected thereby and to charge the amount of any such deduction to
our account.

           (c) In the event a sales or excise tax is levied by State or Federal
authorities, in such form that you are required to pay a tax on sales
represented by any Receivable(s), we agree to reimburse you for the full amount
of taxes payable and agree that all such amounts may be charged to our account.

           (d) We agree to keep proper books of record and accounts in
accordance with sound and accepted accounting practices, which books shall at
all times be open to inspection by you. You and such accountant or other agents
as you may from time to time designate shall have the right, at our expense, to
visit and inspect our properties, assets and books, and to discuss our affairs,
finances and accounts with our officers and employees at such reasonable times
as you may designate, and to make and take away copies of our records. We agree
to do all things necessary or appropriate to permit you to fully exercise your
rights under this Paragraph. We also agree to make available to you from time to
time, upon your request, copies of financial statements prepared by an
accountant acceptable to you. Unless specifically waived in writing, such
financial statements are to be provided to you on a quarterly basis.

           (e) Your failure at any time to insist upon performance of any term
or provision of this Agreement shall not be deemed a waiver of any right
reserved to you, and the waiver of one provision shall not be deemed to be a
waiver of any other provision.

           (f) This Agreement is our complete and final agreement, reflects our
mutual understanding, supersedes any prior agreement or understanding between
us, and may not be modified or amended orally. We acknowledge that, but for the
promises and representations expressly contained in this Agreement, no other
