Section 2

LOAN

Section 2.1. The Loan. Subject to the terms and conditions and
relying on the representations and warranties set forth herein, Lender shall
advance to Borrower, and Borrower shall borrow from Lender, a senior secured
term loan in the amount of One Million and No/100 Dollars ($1,000,000) which is
evidenced by the Note. The proceeds of the Loan must be used by Borrower for
part of the purchase price paid by Borrower to acquire the assets of Seller
pursuant to the Asset Purchase Agreement and to fund the closing costs incurred
in connection with the transactions contemplated in this Agreement.

Section 2.2. Term and Repayment of Loan. The "Term" of the Loan is
seventy-two (72) months and is payable in (i) a single payment on the first day
of August of interest accrued on the unpaid principal balance at the Stated Rate
from the date of the initial Advance to July 31, (ii) two (2) payments of
interest only on the first day of the following two calendar months of interest
accrued on the unpaid principal balance at the Stated Rate for the preceding
calendar

month, (iii) sixty-nine (69) consecutive monthly installments of Twenty Thousand
Fifty-One and 03/100 Dollars ($20,051.03) on the first day of each calendar
month thereafter, with all unpaid principal and interest due and payable in full
on the final installment date. All payments of principal and interest must be
paid in full without setoff, deduction or counterclaim. Lender will debit the
Lock Box Accounts maintained pursuant to the Lock Box Agreement for payment of
each monthly installment of amounts due and payable pursuant to this Agreement.
Borrower shall satisfy any Obligations not paid by such deductions by direct
payment to Lender at ▇▇▇ ▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇.

Section 2.3. Prepayment. The Loan is not subject to prepayment or
redemption in whole or in part prior to the expiration of the Term.

Section 2.4. Late Payments. If Borrower fails to make any payment of
interest or principal, including the payment due upon maturity, when the same is
due and payable and such payment can not be made by debit from the Lock Box
Accounts and such failure continues for five (5) business days after
nonpayment, a late charge by way of damages to the extent provided in this
Section 2.4 is immediately due and payable. Borrower recognizes that default by
Borrower in making the payments herein agreed to be paid when due will result in
the Lender incurring additional expenses, in loss to the Lender of the use of
the money due and in frustration to the Lender in meeting its other commitments.
Lender is entitled to damages for the detriment caused thereby, but it is
extremely difficult and impractical to ascertain the extent of such damages.
Borrower shall pay on demand a sum equal to five cents ($.05) for each one
dollar ($1.00) of each payment which is not received within five (5) business
days after the date it is due and payable is a reasonable estimate of the
damages to the Lender. If any part of the principal or interest is not paid
when due, it thereafter bears interest at the rate of eighteen percent (18%) per
annum from and as of the date of delinquency until paid, provided, however, that
any amount due pursuant to the preceding sentence must be deducted from the
amount due pursuant to this sentence. If the specified interest rate at any
time exceeds the maximum rate allowed by law, then the applicable interest rate
is reduced to the maximum rate allowed by law.

Section 2.5. Conditions to the Closing. The obligation of Lender to
make an Advance on the Closing Date is subject to Lender's determination that
Borrower has satisfied the following conditions on the Closing Date:

(a) The representations and warranties set forth in this Agreement and
in the Other Loan Documents are true and correct on and as of the date hereof

Section 5

PROVISIONS CONCERNING COLLATERAL

Section 5.1. Title. Borrower has good and marketable title to the
Collateral, and the Liens granted to Lender pursuant to this Agreement are fully
perfected first-priority Liens, in and to the Collateral with priority over the
rights of every person in the Collateral, free, clear and unencumbered by any
Liens in favor of any person other than Lender except for Permitted Liens.

Section 5.2. No Warranties. This Agreement is solely a financing
agreement. Borrower acknowledges that with respect to the appropriate
Collateral: the Collateral has or will have been selected and acquired solely
by Borrower for Borrower's purposes; Lender is not the manufacturer, dealer,
vendor or supplier of the Collateral; the Collateral is of a size, design,
capacity, description and manufacturer selected by Borrower; Borrower is
satisfied that the Collateral is suitable and fit for its purposes; and LENDER
HAS NOT MADE AND DOES NOT MAKE ANY WARRANTY OR REPRESENTATION WHATSOEVER, EITHER
EXPRESS OR IMPLIED, AS TO THE FITNESS, CONDITION, MERCHANTABILITY, DESIGN OR
OPERATION OF THE COLLATERAL, ITS FITNESS FOR ANY PARTICULAR PURPOSE, THE VALUE
OF THE COLLATERAL, THE QUALITY OR CAPACITY OF THE MATERIALS IN THE COLLATERAL OR
WORKMANSHIP IN THE COLLATERAL, NOR ANY OTHER REPRESENTATION OR WARRANTY
WHATSOEVER.

Section 5.3. Further Assurances. Borrower shall execute and deliver
to Lender, concurrent with Borrower's execution of this Agreement and at any
time or times hereafter at the request of Lender, all financing statements,
continuation financing statements, security agreements, chattel mortgages,
assignments, endorsements of certificates of title, applications for titles,
affidavits, reports, notices, schedules of accounts, letters of authority and
all other documents Lender may reasonably request, in form satisfactory to
Lender, to perfect and maintain perfected Lender's Liens

in the Collateral and in order to consummate fully all of the transactions
contemplated under the Loan Documents. Borrower hereby irrevocably makes,
constitutes, and appoints Lender (and any of Lender's officers, employees or
agents designated by Lender) as Borrower's true and lawful attorney with power
to sign the name of Borrower on any of the above-described documents or on any
other similar documents that need to be executed, recorded, or filed in order to
perfect or continue perfected Lender's Liens in the Collateral. The appointment
of Lender as Borrower's attorney is irrevocable as long as any Obligations are
outstanding. Any person dealing with Lender is entitled to rely conclusively on
any written or oral statement of Lender that this power of attorney is in
effect.

Section 5.4. Intentionally Deleted.

Section 5.5. Lender's Duty of Care. Lender has no duty of care with
respect to the Collateral except that Lender shall exercise reasonable care with
respect to the Collateral in Lender's custody. Lender will be deemed to have
exercised reasonable care if such property is accorded treatment substantially
equal to that which Lender accords its own property or if Lender takes such
action with respect to the Collateral as the Borrower requests or agrees to in
writing, provided that no failure to comply with any such request nor any
omission to do any such act requested by the Borrower may be deemed a failure to
exercise reasonable care. Lender's failure to take steps to preserve rights
against any parties or property may not be deemed to be failure to exercise
reasonable care with respect to the Collateral in Lender's custody. All risk,
loss, damage or destruction of the Collateral is borne by Borrower except to the
extent Lender breaches the standard of care set forth in this Section 5.5.

Section 5.6. Borrower's Contracts. Schedule 5.6 attached hereto is a
true and complete list of all material contracts and agreements to which
Borrower is a party or will become a party pursuant to the assumption of
Seller's rights and obligations under the terms of the Asset Purchase Agreement.
Borrower remains liable to perform its Obligations under any contracts and
agreements included in the Collateral to the same extent as though this
Agreement had not been entered into and Lender does not have any obligation or
liability under such contracts and agreements by reason of this Agreement or
otherwise.

Section 5.7. Reinstatement of Liens. If, at any time after payment in
full by Borrower of all Obligations and termination of Lender's Liens, any
payments on Obligations previously made by Borrower or any other Person must be
disgorged by Lender for any reason whatsoever (including, the insolvency,
bankruptcy, or reorganization of Borrower or such other Person), this Agreement
and then Lender's Liens granted hereunder are reinstated as to all disgorged
payments as though such payments had not been made, and Borrower shall sign and
deliver to Lender all documents and things necessary to perfect all terminated
Liens.

Section 5.8. Lender Expenses. If Borrower fails to pay any moneys
(whether taxes, assessments, insurance premiums or otherwise) due to third
persons or entities, fails to make any deposits or furnish any required proof of
payment or deposit or fails to discharge any Lien not permitted hereby, all as
required under the terms of this Agreement, then Lender may, to the extent that
it determines that such failure by Borrower could have a material adverse effect
on Lender's

interest in the Collateral, in its discretion and without prior notice to
Borrower, make payment of the same or any part thereof; provided, however,
Lender shall make a reasonable attempt to make a prior notification of Borrower
if a delay in making such payment would not have a material advise impact on
Lender's interest in the Collateral. Any amounts paid or deposited by Lender
constitute Lender Expenses, become part of the Obligations, bear interest at the
rate of eighteen percent (18%) per annum, and are secured by the Collateral. Any
payments made by Lender do not constitute (a) an agreement by Lender to make
similar payments in the future or (b) a waiver by Lender of any Event of Default
under this Agreement. Lender need not inquire as to, or contest the validity of,
any such expense, tax, security interest, encumbrance or Lien, and the receipt
of the usual official notice for the payment of moneys to a governmental entity
is conclusive evidence that the same was validly due and owing.

Borrower shall immediately and without demand reimburse Lender for all
sums expended by Lender that constitute Lender Expenses, and Borrower hereby
authorizes and approves all advances and payments by Lender for items
constituting Lender Expenses.

Section 5.9. Inspection of Collateral and Records. During usual
business hours, Lender may inspect and examine the Collateral and check and test
the same as to quality, quantity, value and condition and Borrower shall
reimburse Lender for its reasonable costs and expenses in so doing. Lender also
has the right at any time or times hereafter, during usual business hours to
inspect and verify Borrower's Books in order to verify the amount or condition
of, or any other matter relating to, the Collateral and Borrower's financial
condition and to copy and make extracts therefrom. Borrower waives the right to
assert a confidential relationship, if any, it may have with any accounting firm
or service bureau in connection with any information requested by Lender
pursuant to this Agreement. Lender may directly contact any such accounting
firm or service bureau in order to obtain such information.

Section 5.10. Waivers. Except as specifically provided for herein,
Borrower waives demand, protest, notice of protest, notice of default or
dishonor, notice of payment and nonpayment, notice of any default, nonpayment at
maturity, release, compromise, settlement, extension or renewal of any or all
commercial paper, accounts, documents, instruments, chattel paper, and
guaranties at any time held by Lender on which Borrower may in any way be
liable.

consent, which may not be unreasonably withheld, provided however that Borrower
shall provide Lender written notice of its intention to incur any such liability
and if such financing can be provided by a third party source such as Lender,
offer Lender a right of first offer to provide such financing. In order to
comply with the right of first offer contained in this Section, Borrower shall
provide Lender with the terms of the proposed financing, including interest
rate, term, amount and collateral for the financing. If Lender declines to
provide the financing on such terms, or does not respond to Borrower's notice
within ten Business Days of receipt thereof, then Borrower can seek alternative
financing on such terms, provided Borrower continues to comply with the first
sentence of this Section. Lender's decision not to provide any such financing
does not waive its right of first offer with respect to any subsequent
financing.

credit;

more, or (ii) at the end of any fiscal quarter Guarantor or its successor, by

REMEDIES

Section 9.1. Specific Remedies. Upon the occurrence of any Event of

(a) Lender may declare all Obligations to be due and payable
immediately, whereupon they immediately become due and payable without
presentment, demand, protest, or notice of any kind, all of which are hereby
expressly waived by Borrower.

(b) Lender may set off against the Obligations all Collateral,
balances, credits, deposits, accounts, or moneys of Borrower then or thereafter
held with Lender, including amounts represented by certificates of deposit.

(c) Lender may enter any premises of Borrower, with or without
judicial process, and take possession of the Collateral; provided however, that
Lender may only exercise such remedy if it may do so without a breach of the
peace. Lender may remove the Collateral and may remove or copy all records
pertaining thereto, or Lender may remain on such premises and use the premises
for the purpose of collecting, preparing and disposing of the Collateral,
without any liability for rent or occupancy charges. Borrower shall, upon
request of Lender, assemble the Collateral and any records pertaining thereto
and make them available at a place designated by Lender that is reasonably
convenient to both parties.

(d) Lender may dispose of the Collateral in its then-existing
condition or, at its election, may take such measures as it deems necessary or
advisable to improve, process, finish, operation, demonstrate and prepare for
sale the Collateral, and may store, ship, reclaim, recover, protect, advertise
for sale or lease, and insure the Collateral. Lender may use and operate
equipment of Borrower in order to process or finish inventory included in the
Collateral. If any Collateral consists of documents, Lender may proceed either
as to the documents or as to the goods represented thereby.

(e) Lender may pay, purchase, contest, or compromise any encumbrance,
charge or Lien that, in the opinion of Lender, appears to be prior or superior
to its Lien and pay all reasonable expenses incurred in connection therewith.

drafts, money orders or other forms of payment of or security for Accounts or
other Collateral; (ii) sign Borrower's name on drafts drawn on Account Debtors
or issuers of letters of credit; and (iii) notify the postal authorities in
Borrower's name to change the address for delivery of Borrower's mail to an
address designated by Lender, receive and open all mail addressed to Borrower,
copy all mail, return all mail relating to Collateral, and hold all other mail
available for pickup by Borrower.

(g) Lender may sell the Collateral at public or private sale and is
not required to repossess Collateral before selling it. Any requirement of
reasonable notice of any disposition of the Collateral is satisfied if such
notice is sent to Borrower, ten (10) days prior to such disposition by any of
the methods provided in Section 11.5 hereof. Borrower will be credited with the
net proceeds of such sale only when they are actually received by Lender, and
Borrower continues to be liable for any deficiency remaining after the
Collateral is sold or collected.

(h) If the sale is to be a public sale, Lender shall also give notice
of the time and place by publishing a notice one time at least five (5) days
before the date of the sale in a newspaper of general circulation in the county
in which the sale is to be held.

(i) To the maximum extent permitted by applicable law, Lender may be
the purchaser of any or all of the Collateral at any public sale and is
entitled, for the purpose of bidding and making settlement or payment of the
purchase price for all or any portion of the Collateral sold at any public sale,
to use and apply all or any part of the Obligations as a credit on account of
the purchase price of any Collateral payable by Lender at such sale.

Section 9.2. Power of Attorney. Borrower hereby appoints Lender (and
any of Lender's officers, employees, or agents designated by Lender) as
Borrower's attorney, with power after the occurrence of an Event of Default:
(a) to endorse Borrower's name on any checks, notes, acceptances, money orders,
drafts or other forms of payment or security that may come into Lender's
possession; (b) to sign Borrower's name on drafts against Account Debtors, on
schedules and assignments of Accounts, on verifications of Accounts, and on
notices to Account Debtors; (c) to notify the post office authorities to change
the address for delivery of Borrower's mail to an address designated by Lender,
to receive and open all mail addressed to Borrower and to retain all mail

relating to the Collateral and forward all other mail to Borrower; (d) to send
requests for verification of Accounts; (e) to execute UCC Financing Statements;
and (f) to do all things necessary to carry out this Agreement. The appointment
of Lender as Borrower's attorney and each and every one of Lender's rights and
powers, being coupled with an interest, are irrevocable as long as any
Obligations are outstanding. Lender shall not exercise the power granted in
clauses 9.2(a) through 9.2(c) prior to the occurrence of an Event of Default and
shall not exercise the power granted in clause 9.2(d) prior to notification of
Borrower of its intent to do so, but such limitations do not limit the
effectiveness of such power of attorney at any time. Any person dealing with
Lender is entitled to rely conclusively on any written or oral statement of
Lender that this power of attorney is in effect. Lender may also use Borrower's
stationery in connection with exercising its rights and remedies and performing
the Obligations of Borrower.

Section 9.3. Expenses Secured. All expenses, including reasonable
attorney fees, incurred by Lender in the exercise of its rights and remedies
provided in this Agreement, in the Other Loan Documents or by law shall be
payable by Borrower to Lender, are part of the Obligations, and are secured by
the Collateral.

Section 9.4. Equitable Relief. Borrower recognizes that in the event
Borrower fails to perform, observe, or discharge any of its Obligations or
liabilities under this Agreement, in certain cases no remedy of law will provide
adequate relief to Lender, and Lender is entitled to temporary and permanent
injunctive relief in any such case without the necessity of proving actual
damages.

Section 9.5. Remedies Are Cumulative. No remedy set forth herein is
exclusive of any other available remedy or remedies, but each is cumulative and
in addition to every other right or remedy given under this Agreement or under
any other agreement between Lender and Borrower or Guarantor or now or hereafter
existing at law or in equity or by statute. Lender may pursue its rights and
remedies concurrently or in any sequence, and no exercise of one right or remedy
may be deemed to be an election. No delay by Lender constitutes a waiver,
election, or acquiescence by it. Borrower on its behalf waives any rights to
require Lender to proceed against Guarantor or any other party; or proceed
against or exhaust any security held from Guarantor or any other party. Lender
may at any time and from time to time, without notice to, or consent of,
Borrower, and without affecting or impairing the obligation of Borrower
hereunder do any of the following: (i) renew or extend any obligations of
Guarantor, or of any other party at any time directly or contingently liable for
payment of any of the obligations of Guarantor; (ii) accept partial payments of
the obligations of Guarantor; (iii) settle, release (by operation of law or
otherwise), compound, compromise, collect or liquidate any of the obligations of
Guarantor and the security therefor in any manner; or (iv) consent to the
transfer or sale of any security or bid and purchase at any sale of any security
of Guarantor. The validity of this Agreement and the Obligations of Borrower
are not terminated, affected or impaired by reason of the waiving, delaying,
exercising or non-exercising, of any of Lender's rights against Guarantor or as
a result of the substitution, release, repossession, sale, disposition or
destruction of any Collateral securing any obligations of Guarantor. Borrower
is not released or discharged, either in whole or in part, by Lender's failure
or delay to perfect or continue the perfection of any security interest in any
Collateral which secures the obligations of Guarantor or to protect the property
covered by such security interest.

Section 10

INDEMNITY

Section 10.1. General Indemnity. BORROWER SHALL UNCONDITIONALLY
PROTECT, INDEMNIFY, DEFEND AND HOLD HARMLESS LENDER AND ITS DIRECTORS, OFFICERS,
EMPLOYEES AND AGENTS FROM AND AGAINST ANY LOSS, COST, LIABILITY (INCLUDING
NEGLIGENCE, TORT AND STRICT LIABILITY), EXPENSE, DAMAGE, SUITS, DEMANDS OR
CLAIMS (INCLUDING FEES AND DISBURSEMENTS OF COUNSEL) ON ACCOUNT OF ANY SUIT OR
PROCEEDING BEFORE ANY GOVERNMENTAL AUTHORITY WHICH ARISES FROM THE TRANSACTIONS
CONTEMPLATED IN THIS AGREEMENT OR OTHERWISE ARISING IN CONNECTION WITH OR
RELATING TO THE LOAN AND ANY SECURITY THEREFOR, UNLESS SUCH SUIT, CLAIM OR
DAMAGES ARE CAUSED BY THE GROSS NEGLIGENCE OR INTENTIONAL MALFEASANCE OF LENDER
OR ITS DIRECTORS, OFFICER, AGENTS OR EMPLOYEES. Upon receiving knowledge of any
suit, claim or demand asserted by a third-party that Lender believes is covered
by this indemnity, Lender shall give Borrower timely notice of the matter and an
opportunity to defend it, at Borrower's sole cost and expense, with legal
counsel acceptable to Lender. Lender may, at its option, also require Borrower
to so defend the matter. This obligation on the part of Borrower survives the
termination of this Agreement and the repayment of the Note.

Section 10.2. Specific Environmental Indemnity. Borrower shall
unconditionally protect, indemnify, defend and hold harmless Lender, its
directors, officers, employees and agents against any loss, cost, liability
(including negligence, tort and strict liability), expense, damage, suits,
demands or claim (including fees and disbursements of counsel) arising under any
Environmental Laws having jurisdiction over the property or assets of Borrower
or any portion thereof or its use.

Section 11

MISCELLANEOUS

Section 11.1. Delay and Waiver. No delay or omission to exercise any
right impairs any such right or be a waiver thereof, but any such right may be
exercised from time to time and as often as may be deemed expedient. A waiver
on one occasion is limited to that particular occasion.

Section 11.2. Complete Agreement. This Agreement and the Schedules
are the complete agreement of the parties hereto and supersede all previous
understandings relating to the subject matter hereof. This Agreement may be
amended only by an instrument in writing that explicitly states that it amends
this Agreement and is signed by the party against whom enforcement of the
amendment is sought. This Agreement may be executed in counterparts, each of
which will be an original and all of which will constitute a single agreement.

Section 11.3. Severability; Headings. If any part of this Agreement
or the application thereof to any person or circumstance is held invalid, the
remainder of this Agreement is unaffected thereby. The section headings herein
are included for convenience only and may not be deemed to be a part of this
Agreement.

Section 11.4. Binding Effect. This Agreement is binding upon and
inures to the benefit of the respective legal representatives, successors and
assigns of the parties hereto; provided however, Borrower may not assign any of
its rights or delegate any of its Obligations hereunder. Lender (and any
subsequent assignee) may transfer and assign this Agreement and deliver the
Collateral to the assignee, who thereupon has all of the rights of Lender; and
Lender (or such subsequent assignee who in turn assigns as aforesaid) is then
relieved and discharged of any responsibility or liability with respect to this
Agreement and said Collateral.

Section 11.5. Notices. Any notices under or pursuant to this
Agreement are deemed duly sent when delivered in hand or when mailed by
