Event of Default, Lender may, without notice or demand, exercise in any
jurisdiction in which enforcement hereof is sought, the following rights and
remedies, in addition to the rights and remedies available to Lender under the
Loan Documents, the rights and remedies of a secured party under the Uniform
Commercial Code and all other rights and remedies available to Lender under
applicable law, all such rights and remedies being cumulative and enforceable
alternatively, successively or concurrently:

10.1.1. Declare the Note, all interest accrued and unpaid thereon and all
other Obligations to be immediately due and payable and the same shall thereupon
become immediately due and payable without presentment, demand for payment,
protest or notice of any kind, all of which are hereby expressly waived.

10.1.2. Institute any proceeding or proceedings to enforce the Obligations
and any Liens of Lender.

10.1.3. Take possession of the Collateral, and for that purpose, so far as
Borrower may give authority therefor, enter upon any premises on which the
Collateral or any part thereof may be situated and remove the same therefrom
without any liability for suit, action or other proceeding, and require
Borrower, at Borrower's expense, to assemble and deliver the Collateral to such
place or places as Lender may designate.

10.1.4. Operate, manage and control the Collateral (including use of the
Collateral and any other property or assets of Borrower in order to continue or
complete performance of Borrower's obligations under any contracts of Borrower),
or permit the Collateral or any portion thereof to remain idle or store the
same, and collect all rents and revenues therefrom and sell or otherwise dispose
of any or all of the Collateral upon such terms and under such conditions as
Lender, in its sole discretion, may determine, and purchase or acquire any of
the Collateral at any such sale or other disposition, all to the extent
permitted by applicable law.

10.1.5. Enforce Borrower's rights against any account debtors and other
obligors.

10.1.6. Cease making advances hereunder and under any other commitments or
credit accommodations of Lender to Borrower and stop and retract the making of
any advance hereunder or thereunder which may have been requested by Borrower.

10.2. Power of Attorney. Effective upon the occurrence of an Event of
Default, Borrower hereby designates and appoints Lender and its designees as
attorney-in-fact of Borrower, irrevocably and with power of substitution, with
authority to endorse Borrower's name on any notes, acceptances, checks, drafts,
money orders, instruments or other evidences of payment or proceeds of the
Collateral that may come into Lender's possession; to execute proofs of claim
and loss; to adjust and compromise any claims under insurance policies; and to
perform all other acts necessary and advisable, in Lender's sole discretion, to
carry out and enforce this Agreement and the Loan Documents. All acts of said
attorney or designee are hereby ratified and approved by Borrower and said
attorney or designee shall not be liable for any acts of commission or omission
nor for any error of judgment or mistake of fact or law. This power of attorney
is coupled with an interest and is irrevocable so long as any of the Obligations
remain unpaid or unperformed or there exists any commitment by Lender which
could give rise to any Obligations.

10.3. Costs and Expenses. Borrower agrees to pay to Lender on demand the
amount of all expenses paid or incurred by Lender in consulting with counsel
concerning any of its rights hereunder, under the Loan Documents or under
applicable law, all expenses, including reasonable attorneys' fees and court
costs paid or incurred by Lender in exercising or enforcing any of its rights
hereunder, under the Loan Documents or under applicable law together with
interest on all such expenses paid by Lender at the default rate under the Notes
and calculated in the manner provided in the Note. The provisions of this
Section shall survive the termination of this Agreement and the payment of all
other Obligations.

11. MISCELLANEOUS.

11.1. Performance for Borrower. Borrower agrees and hereby authorizes that
Lender may, in Lender's sole discretion, but Lender shall not be obligated to,
whether or not an Event of Default shall have occurred, advance funds on behalf
of Borrower, without prior notice to Borrower, in order to insure Borrower's
compliance with any covenant, warranty, representation or agreement of Borrower
made in or pursuant to this Agreement or any of the Loan Documents, to continue
or complete, or cause to be continued or completed, performance of Borrower's
obligations under any contracts of Borrower, to cover overdrafts in any checking
or other accounts of Borrower at Lender or to preserve or protect any right or
interest of Lender in the Collateral or under or pursuant to this Agreement or
any of the Loan Documents, including, without limitation, the payment of any
insurance premiums or taxes and the satisfaction or discharge of any judgment or
any Lien upon the Collateral or other property or assets of Borrower; provided,
however, that the making of any such advance by Lender shall not constitute a
waiver by Lender of any Event of Default with respect to which such advance is
made nor relieve Borrower of any such Event of Default. Borrower shall pay to
Lender upon demand all such advances made by Lender with interest thereon at the
highest rate and calculated in the manner provided in the Note. All such
advances shall be deemed to be included in the Obligations and secured by the
security interest granted Lender hereunder; provided, however, that the
provisions of this Section shall survive the termination of this Agreement and
Lender's security interest hereunder and the payment of all other Obligations.

11.2. Expenses. Whether or not any of the transactions contemplated hereby
shall be consummated, Borrower agrees to pay to Lender on demand the amount of
all expenses paid or incurred by Lender (including the reasonable fees and
expenses of its counsel) in connection with the preparation of all written
commitments of Lender antedating this Agreement, this Agreement and the Loan
Documents and all documents and instruments referred to herein and all expenses
paid or incurred by Lender in connection with the filing or recordation of all
financing statements and instruments as may be required by Lender at the time
of, or subsequent to, the execution of this Agreement, including, without
limitation, all documentary stamps, recordation and transfer taxes and other
costs and taxes incident to recordation of any document or instrument in
connection herewith. Borrower shall pay Lender $25.00 for each response to
Borrower's request for an accounting or confirmation of a list of Collateral or
statement of account exceeding one request per 6-month period. Borrower agrees
to save harmless and indemnify Lender from and against any liability resulting
from the failure to pay any required documentary stamps, recordation and
transfer taxes, recording costs or any other expenses incurred by Lender in
connection with this Agreement. The provisions of this Section shall survive the
termination of this Agreement, Lender's security interest, and the payment of
all other Obligations.

11.3. Applications of Payments and Collateral. Except as may be otherwise
specifically provided in this Agreement, all Collateral and proceeds of
Collateral coming into Lender's possession and all payments made by any Obligor
may be applied by Lender to any of the Obligations, whether matured or
unmatured, as Lender shall determine in its sole but reasonable discretion.

11.4. Waivers by Borrower. Borrower hereby waives, to the extent the same
may be waived under applicable law: (a) notice of acceptance of this Agreement;
(b) all claims, causes of action and rights of Borrower against Lender on
account of actions taken or not taken by Lender in the exercise of Lender's
rights or remedies hereunder, under the Loan Documents or under applicable law;
(c) all claims of Borrower for failure of Lender to comply with any requirement
of applicable law relating to enforcement of Lender's rights or remedies
hereunder, under the Loan Documents or under applicable law; (d) all rights of
redemption of Borrower with respect to the Collateral; (e) in the event Lender
seeks to repossess any or all of the Collateral by judicial proceedings, any
bond(s) or demand(s) for possession which otherwise may be necessary or
required; (f) presentment, demand for payment, protest and notice of non-payment
and all exemptions; (g) any and all other notices or demands which by applicable
law must be given to or made upon Borrower by Lender; (h) settlement, compromise
or release of the obligations of any person primarily or secondarily liable upon
any of the Obligations; (i) trial by jury in any action or proceeding of any
kind or nature in connection with any of the Obligations, this Agreement or any
of the Loan Documents; and (j) substitution, impairment, exchange or release of
any Collateral for any of the Obligations. Borrower agrees that Lender may
exercise any or all of its rights and/or remedies hereunder, under the Loan
Documents and under applicable law without resorting to and without regard to
any Collateral or sources of liability with respect to any of the Obligations.
Upon termination of this Agreement and Lender's security interest hereunder and
payment of all Obligations, within 45 days following Borrower's request to
Lender, Lender shall release control of any security interest in the Collateral
perfected by control and Lender shall send Borrower a statement terminating any
financing statement filed against the Collateral.

11.5. Waivers by Lender. Neither any failure nor any delay on the part of
Lender in exercising any right, power or remedy hereunder, under any of the Loan
Documents or under applicable law shall operate as a waiver thereof, nor shall a
single or partial exercise thereof preclude any other or further exercise
thereof or the exercise of any other right, power or remedy.

11.6. Lender's Setoff. Lender shall have the right, in addition to all
other rights and remedies available to it, following an Event of Default, to set
off against any Obligations due Lender, any debt owing to Borrower by Lender,
including, without limitation, any funds in any checking or other account now or
hereafter maintained by Borrower at Lender. Borrower hereby confirms Lender's
right to banker's lien and setoff, and nothing in this Agreement or any of the
Loan Documents shall be deemed a waiver or prohibition of Lender's right of
banker's lien and setoff.

11.7. Modifications. No modifications or waiver of any provision of this
Agreement or any of the Loan Documents, and no consent by Lender to any
departure by Borrower therefrom, shall in any event be effective unless the same
shall be in writing, 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 upon Borrower in any case shall entitle Borrower to any other or further
notice or demand in the same, similar or other circumstances.

11.8. Notices. Any notice or other communication in connection with this
Agreement, if by registered or certified mail, shall be deemed to have been
given when received by the party to whom directed, or, if by mail but not
registered or certified, when deposited in the mail, postage prepaid, provided
that any such notice or communication shall be addressed to a party hereto as

construction of this Agreement and the Loan Documents shall be governed by the

proceeding instituted against Borrower with respect to any of the Obligations,
the Collateral, this Agreement or any of the Loan Documents may be brought in

execution hereof, Borrower hereby irrevocably waives any objection and any right
of immunity on the ground of venue, the convenience of the forum or the
jurisdiction of such courts or from the execution of judgments resulting
therefrom. Borrower hereby irrevocably accepts and submits to the jurisdiction
of the aforesaid courts in any such suit, action or proceeding.

representations and warranties made herein and in the Loan Documents shall

shall continue in full force and effect until all Obligations have been paid in
full, there exists no commitment by Lender which could give rise to any
Obligations and all appropriate termination statements have been filed

Agreement any of the parties hereto is referred to, such reference shall be
deemed to include the successors and assigns of such party. In the event that

Collateral, Lender shall give written notice to Borrower of any such assignment.
All covenants, agreements, representations and warranties by or on behalf of
Borrower which are contained in this Agreement and the Loan Documents shall
inure to the benefit of Lender, its successors and assigns. Borrower may not
assign this Agreement or any of its rights hereunder without the prior written
consent of Lender.

thereof, of this Agreement or any of the Loan Documents shall for any reason be
found or held invalid or unenforceable by any court or governmental agency of
competent jurisdiction, such invalidity or unenforceability shall not affect the
remainder of such term, provision or condition nor any other term, provision or
condition, and this Agreement and the Loan Documents shall survive and be
construed as if such invalid or unenforceable term, provision or condition had
not been contained therein.

11.12. Merger and Integration. This Agreement and the attached Schedules
(if any) contain the entire agreement of the parties hereto with respect to the
matters covered and the transactions contemplated hereby, and no other
agreement, statement or promise made by any party hereto, or by any employee,
officer, agent or attorney of any party hereto, which is not contained herein
shall be valid or binding.

11.13. WAIVER OF JURY TRIAL. BORROWER HEREBY (a) COVENANTS AND AGREES NOT
TO ELECT A TRIAL BY JURY OF ANY ISSUE TRIABLE OF RIGHT BY A JURY, AND (b) WAIVES
TRIAL BY JURY IN ANY ACTION OR PROCEEDING TO WHICH LENDER AND BORROWER MAY BE
PARTIES, ARISING OUT OF, IN CONNECTION WITH OR IN ANY WAY PERTAINING TO THIS
