1. CROSS-SECURITY. Debtor grants to Secured Party, its affiliates (including,
without limitation, any direct or indirect parent, subsidiary or sister entity),
successors and assigns a security interest in the Collateral (separate and
distinct from and subordinate to the security interest granted to Secured Party
on the first page of this Agreement) to secure the payment and performance of
all debts and all liabilities of Debtor to Secured Party of every kind and
character, whether now existing or hereafter arising, and whether direct,
indirect, absolute, contingent, primary, secondary, or otherwise, or to any
affiliates (including, without limitation, any direct or indirect parent,
subsidiary or sister entity), successors or assignees of Secured Party, now
existing or hereafter arising, whether under this Agreement or any other
agreement, and whether due directly or by assignment. The security interest
granted herein shall continue to be effective regardless of any retaking or
redelivery of the Collateral to Debtor. Upon any assignment of this Agreement by
Secured Party, the assignee shall then be deemed the Secured Party for the
purposes of this paragraph.

2. ADDITIONAL WARRANTIES AND AGREEMENTS. Debtor warrants and agrees that: the
execution of and performance by Debtor under the terms of this Agreement has
been approved for Debtor by all necessary action and by Debtor's partners or
board of directors, as applicable; the Equipment is currently and will continue
be maintained in good operating condition, repair and appearance and is
currently and will continue be used and operated with care only by qualified
personnel in the regular course of Debtor's business and in conformity with all
applicable governmental laws and regulations, manufacturer's specifications and
the restrictions contained in any insurance policy insuring the Equipment; the
Equipment is not currently and will not be used in conjunction with the storage,
transportation or disposal of substances considered to be toxic and/or hazardous
or in conjunction with any activity or for any use that would subject the
Equipment to seizure or confiscation by any governmental body; and the Equipment
is currently located at and will be kept by Debtor at the location set forth for
it on the reverse side of this Agreement and will not be removed from said
location without the prior written consent of Secured Party, except that if the
Equipment is of a type which is mobile and normally used by Debtor at more than
one location, Debtor may use the Equipment away from said location in the
regular course of Debtor's business provided that (a) if the Equipment is not
returned to said location within 30 days, Debtor will immediately thereafter,
and each 30 days thereafter until the Equipment is returned, report the then
current location of the Equipment to Secured Party in writing and (b) the
Equipment shall not be removed from the State(s) of use indicated on the
reverse side of this Agreement. Secured Party shall have the right to inspect
the Equipment at all reasonable times and from time to time.

      Debtor further warrants and agrees that: the security interest in the
Collateral granted to and/or retained by Secured Party is and will continue to
be superior to any title to or interest in the Equipment now or hereafter held
or claimed by any other party; the Collateral is free from and will be kept free
from all liens, claims, security interests and encumbrances (whether superior or
inferior to the interests of Secured Party) other than that created by this
Agreement; notwithstanding Secured Party's interest in proceeds, Debtor will not
and will not allow any other party to consign, sell, rent, lend, encumber,
pledge, transfer, secrete or otherwise dispose of any of the Collateral without
Secured Party's prior written consent; Debtor will do everything Secured Party
deems necessary or expedient to perfect or preserve the interests granted to
Secured Party under this Agreement and the first priority of such interests; any
Manufacturer's Statement or Certificate of Origin or Certificate of Title
relating to the Equipment shall be immediately delivered to Secured Party and,
if a Certificate of Title or registration is required for any item of Equipment,
Debtor will cooperate with Secured Party in obtaining the Certificate of Title
or registration disclosing the interests of Debtor and Secured Party in the
Equipment; Debtor will defend any action, proceeding or claim affecting the
Collateral or the interests of Secured Party in the Collateral; Debtor shall
promptly pay all amounts payable in conjunction with the storage, maintenance or
repair of the Equipment and all taxes, assessments, license fees and other
public or private charges levied or assessed in conjunction with the operation
or use of the Equipment or levied or assessed against the Collateral, this
Agreement or any accompanying note except for those which are being contested by
Debtor in good faith by appropriate proceedings and which do not constitute a
lien or encumbrance upon the Collateral; and Debtor will from time to time
furnish Secured Party with such financial statements and other information as
Secured Party may reasonably request.

3. INSURANCE AND RISK OF LOSS. Debtor shall at all times bear all risk of loss
of, damage to or destruction of the Equipment. Debtor agrees to immediately
procure and maintain insurance on the Equipment, for the full insurable value
thereof and for the life of this Agreement, in the form of "All Risk" or similar
insurance (insuring the Equipment for fire, extended coverage, vandalism, theft
and collision and containing only those exclusions from coverage which are
acceptable to Secured Party) plus such other insurance as Secured Party may
specify from time to time, all in form and amount and with insurers satisfactory
to Secured Party. Debtor agrees to deliver promptly to Secured Party
certificates or, if requested, policies of insurance satisfactory to Secured
Party, each with a standard long-form loss-payable endorsement naming Secured
Party or assigns as loss-payee and providing that Secured Party's rights under
such policy will not be invalidated by any act, omission or neglect of anyone
other than Secured Party and containing the insurer's agreement to give 30 days
prior written notice to Secured Party before any cancellation of or material
change in the policy(s) will be effective as to Secured Party, whether such
cancellation or change is at the direction of Debtor or insurer. Secured Party's
acceptance of policies in lesser amounts or risks will not be a waiver of
Debtor's obligation to procure insurance complying with the provisions hereof
promptly after notice from Secured Party. Debtor assigns to Secured Party all
proceeds of any physical damage or credit insurance for which a charge is stated
in this Agreement or which is maintained by Debtor in accordance herewith,
including returned and unearned premiums, up to the amount owing hereunder by
Debtor. Secured Party will not have the right to cancel any such insurance
without Debtor's consent prior to the occurrence of an event of default and the
repossession, loss or destruction of the Equipment. Debtor directs all insurers
to pay such proceeds solely to the order of Secured Party for application to
Debtor's indebtedness to Secured Party. Secured Party may, at its option, apply
any such proceeds received by Secured Party to the final maturing installments
due hereunder in the inverse order of their maturity.

4. PERFORMANCE BY SECURED PARTY. If Debtor fails to perform any of Debtor's
obligations pursuant to Paragraphs 1, 2, or 3 above, Secured Party may perform
the same for the account of Debtor. Any such action by Secured Party will be in
Secured Party's sole discretion and Secured Party will not be obligated in any
way to do so. Secured Party's performance on behalf of Debtor will not obligate
Secured Party to perform the same or any similar act in the future and will not
cure or waive Debtor's failure of performance as an event of default hereunder.
All sums advanced or costs and expenses incurred by Secured Party pursuant to
this Paragraph, including the reasonable fees of any attorney retained by
Secured Party, will be for the account of Debtor, will constitute indebtedness
secured by Secured Party's security interest in the Collateral, will bear
interest at the rate as specified on the reverse side of this Agreement in the
event of acceleration and, unless Secured Party, in Secured Party's sole
discretion agrees otherwise in writing, shall be immediately due and payable.

5. EVENTS OF DEFAULT. Time is of the essence. An event of default will occur if:

affiliate (including, without limitation, any direct or indirect parent,
subsidiary or sister entity), successor or assignee of Secured Party under this
Agreement or under the terms of any promissory note delivered in conjunction

shall hereinafter be collectively referred to as "Governmental Authority"); (m)
if anyone in the control, custody or possession of the Collateral or the Debtor

the indebtedness or obligation of Debtor to Secured Party. Secured Party's
inaction with respect to an event of default shall not be a waiver of such
default and Secured Party's waiver of any default shall not be a waiver of any
other default.

6. REMEDIES UPON DEFAULT. Upon the occurrence of an event of default, and at any
time thereafter as long as the default continues. Secured Party may, at its
option, with or without notice to Debtor (i) declare this Agreement to be in
default (ii) declare the indebtedness hereunder to be immediately due and
payable, (iii) declare all other debts then owing by Debtor to Secured Party or
any affiliate (including, without limitation any direct or indirect parent,
subsidiary or sister entity), successor or assignee of Secured Party to
immediately due and payable, (iv) cancel any insurance and credit any refund to
the indebtedness, and (v) exercise all of the rights and remedies of a Secured
Party under the Uniform Commercial Code and any other applicable laws,
including, without limitation, the right to require Debtor to assemble the
Equipment and deliver it to Secured Party at a place to be designated by Secured
Party which is reasonably convenient to both parties, and to lawfully enter any
premises where the Collateral may be without judicial process and take
possession thereof. Acceleration of any or all indebtedness, if so elected by
Secured Party, shall be subject to all applicable laws including those
pertaining to refunds and rebates of unearned charges. Any property other than
the Collateral which is in or upon the Equipment at the time of repossession may
be taken and held without liability until its return is requested by Debtor. Any
sale or other disposition of any of the Equipment may be made at public or
private sale or through public auction at the option of Secured Party. Secured
Party may buy at any sale and become the owner of the Equipment. Unless

before the time of sale or other disposition. Debtor agrees that Secured Party
may bring any legal proceedings it deems necessary to enforce the payment and
performance of Debtor's obligations hereunder in any court in the State shown in
Secured Party's address set forth herein, and service of process may be made

relating to this Agreement will be considered received when delivered in person
(including by facsimile transmission) or mailed to Debtor at the address of
Debtor contained in this Agreement or at any address later designated by Debtor
to Secured Party in writing. The filing by Secured Party of any action or
proceeding with respect to the Equipment or any of Debtor's obligations
hereunder shall not constitute an election by Secured Party of Secured Party's
remedies or a waiver of Secured Party's rights to take possession of the
Equipment as provided above. Expenses of retaking, holding, preparing for sale,
selling and the like shall include (a) the reasonable fees of any attorneys
retained by Secured Party, (b) any amounts advanced or expenses incurred by
Secured Party pursuant to Paragraph 4 hereof and (c) all other legal and other
expenses incurred by Secured Party. Debtor agrees that it is liable for and will
promptly pay any deficiency resulting from any disposition of Collateral after
default and all costs and expenses, including me reasonable fees of any
attorney, incurred by Secured Party in the collection of any such deficiency.
Secured Party may sell the Equipment without giving any warranties as to the
Equipment. Secured Party may disclaim any warranties of title, possession, quiet
enjoyment, or the like. This procedure will not be considered to adversely
affect the commercial reasonableness of any sale of the Equipment.

7. POWER OF ATTORNEY. DEBTOR HEREBY APPOINTS SECURED PARTY OR ANY OFFICER,
EMPLOYEE OR DESIGNEE OF SECURED PARTY, OR ANY ASSIGNEE OF SECURED PARTY (OR ANY
DESIGNEE OF SUCH ASSIGNEE) AS DEBTOR'S ATTORNEY-IN-FACT TO IN DEBTOR'S OR

LOSS IN ORDER TO REALIZE THE BENEFITS OF ANY INSURANCE POLICY INSURING THE

OPINION IS NECESSARY TO PERFECT AND/OR GIVE PUBLIC NOTICE OF THE INTERESTS OF
SECURED PARTY IN ANY COLLATERAL THAT SECURES OR THAT MAY SECURE ANY OBLIGATIONS
OR INDEBTEDNESS OF DEBTOR TO SECURED PARTY; AND (c) ENDORSE DEBTOR'S NAME ON ANY
REMITTANCE REPRESENTING PROCEEDS OF ANY INSURANCE RELATING TO THE COLLATERAL OR
THE PROCEEDS OF THE SALE, LEASE OR OTHER DISPOSITION OF THE COLLATERAL (WHETHER
OR NOT THE SAME IS A DEFAULT HEREUNDER). This power is coupled with an interest
and is irrevocable so long as indebtedness remains unpaid from Debtor to Secured
Party. Debtor agrees to execute and deliver to Secured Party, upon Secured
Party's request, such documents, writings, records and assurances as Secured
Party deems necessary or advisable for the confirmation or perfection of the
security interest in Collateral and Secured Party's rights hereunder, including
such documents, writings records and assurances as Secured Party may require for
filing or recording. Debtor authorizes Secured Party or any officer, employee or
designee of Secured Party or any assignee of Secured Party (or any designee of
such assignee) to file a financing statement describing the Collateral. Debtor
authorizes Secured Party or any officer, employee or designee of Secured Party
or any assignee of Secured Party (or any designee of such assignee) to file
financing statements covering assets of Debtor other than the Collateral

consent of Secured Party. Secured Party or any assignee or successor of Secured
Party shall have the right to transfer, sell or assign all or any portion of
this Agreement or the indebtedness and/or obligations hereunder, without notice,
acknowledgement or consent from Debtor. Upon assignment, the term "Secured
Party" shall mean and refer to any assignee who is the holder of this Agreement.
The assignor will not be the assignee's agent for any purpose. Debtor waives and
will not assert against any assignee of Secured Party any claims, counterclaim,
claims in recoupment, abatement, reduction, defenses, or set-offs for breach of
warranty or for any other reason which Debtor could assert against Secured
Party, except defenses which cannot be waived under the Uniform Commercial Code.
Upon full payment of all obligations secured by this Agreement, the assignee may
deliver all original papers to the assignor for Debtor.

9. PRIVACY WAIVER. Secured Party may receive from and disclose to any
individual, corporation, business trust, association, company, partnership,
joint venture, or other entity (herein collectively, the "Entity"), including,
without limiting the generality of the foregoing, Secured Party's parent or any
affiliate or any subsidiary of Secured Party and any credit reporting agency or
other entity whether or not related to Secured Party for any purpose,
information about Debtor's accounts, credit application and credit experience
with Secured Party and Debtor authorizes any Entity to release to Secured Party
any information related to Debtor's accounts, credit experience and account
information regarding the Debtor. THIS SHALL BE CONTINUING AUTHORIZATION FOR ALL
PRESENT AND FUTURE DISCLOSURES OF DEBTOR'S ACCOUNT INFORMATION, CREDIT
APPLICATION AND CREDIT EXPERIENCE ON DEBTOR MADE BY SECURED PARTY, OR ANY ENTITY
REQUESTED TO RELEASE SUCH INFORMATION TO SECURED PARTY.

10. DEBIT TRANSACTIONS. Secured Party may but shall not be required to offer
Debtor the option of paying any of Debtor's obligations to Secured Party through
printed checks ("Debit Transactions") drawn pursuant to this authorization upon
Debtor's checking account, using Debtor's checking account number, bank routing
code and other information which Debtor provides to Secured Party prior to the
first Debit Transaction. Debtor authorizes Secured Party to initiate Debit
Transactions from Debtor's checking account in the amount necessary to pay the
installment payments, delinquency charges, or such other amounts as may now or
hereafter be due hereunder or under any other present or future agreement with
or which is held by Secured Party plus a fee of ten dollars ($10.00) for each
Debit Transaction initiated by Secured Party. In the event applicable law
prohibits or restricts the amount of such fee, the fee chargeable under this
provision shall be limited and/or restricted in accordance with applicable law.
Secured Party may from time to time increase or decrease the Debit Transaction
fee upon prior written notice addressed to Debtor's last known address as shown
on the records of Secured Party and such increase or decrease shall be effective
as stated in the written notice. Unless prohibited by applicable law, Debtor's
continued use of Debit Transactions after the effective date specified in such
notice shall conclusively establish Debtor's agreement to pay the new Debit
Transaction fee stated therein. Debtor authorizes Secured Party or any officer,
employee or designee of Secured Party to endorse Debtor's name as drawer on any
printed check drawn in accordance with this authorization. Until cancelled by
Debtor, this authorization shall be valid for all Debit Transactions Secured
Party initiates in payment of Debtor's obligations hereunder or under any other
present or future agreement with or which is held by Secured Party. This
authorization may be canceled at any time by Debtor giving at least three (3)
business days prior written notice to Debtor's bank and Secured Party. Payment
by Debit Transactions is not required by Secured Party nor is its use a factor
in the approval of credit.

1. CROSS-SECURITY. Debtor grants to Secured Party, its affiliates (including,
without limitation, any direct or indirect parent, subsidiary or sister entity),
successors and assigns a security interest in the Collateral (separate and
distinct from and subordinate to the security interest granted to Secured party
on the first page of this Agreement) to secure the payment and performance of
all debts and all liabilities of Debtor to Secured Party of every kind and
character, whether now existing or hereafter arising, and whether direct,
indirect, absolute, contingent, primary, secondary, or otherwise, or to any
affiliates (including, without limitation, any direct or indirect parent,
subsidiary or sister entity), successors or assignees of Secured Party, now
existing or hereafter arising whether under this Agreement or any other
agreement, and whether due directly or by assignment. The security interest
granted herein shall continue to be effective regardless of any retaking or
redelivery of the Collateral to Debtor. Upon any assignment of this Agreement by
Secured Party, the assignee shall then be deemed the Secured Party for the
purposes of this paragraph.

2. ADDITIONAL WARRANTIES AND AGREEMENTS. Debtor warrants and agrees that: the
execution of and performance by Debtor under the terms of this Agreement has
been approved for Debtor by all necessary action and by Debtor's partners or
board of directors, as applicable; the Equipment is currently and will continue
be maintained in good operating condition, repair and appearance and is
currently and will continue be used and operated with care only by qualified
personnel in the regular course of Debtor's business and in conformity with all
applicable governmental laws and regulations, manufacturer's specifications and
the restrictions contained in any insurance policy insuring the Equipment; the
Equipment is not currently and will not be used in conjunction with the storage,
transportation or disposal of substances considered to be toxic and/or hazardous
or in conjunction with any activity or for any use that would subject the
Equipment to seizure or confiscation by any governmental body; and the Equipment
is currently located at and will be kept by Debtor at the location set forth for
it on the reverse side of this Agreement and will not be removed from said
location without the prior written consent of Secured Party, except that if the
Equipment is of a type which is mobile and normally used by Debtor at more than
one location, Debtor may use the Equipment away from said location in the
regular course of Debtor's business provided that (a) if the Equipment is not
returned to said location within 30 days, Debtor will immediately thereafter,
and each 30 days thereafter until the Equipment is returned, report the then
current location of the Equipment to Secured Party in writing and (b) the
Equipment shall not be removed from the State(s) of use indicated on the
reverse side of this Agreement. Secured Party shall have the right to inspect
the Equipment at all reasonable times and from time to time.

      Debtor further warrants and agrees that: the security interest in the
Collateral granted to and/or retained by Secured Party is and will continue to
be superior to any title to or interest in the Equipment now or hereafter held
or claimed by any other party; the Collateral is free from and will be kept free
from all liens, claims, security interests and encumbrances (whether superior or
inferior to the interests of Secured Party) other than that created by this
Agreement; notwithstanding Secured Party's interest in proceeds, Debtor will not
and will not allow any other party to consign, sell, rent, lend, encumber,
pledge, transfer, secrete or otherwise dispose of any of the Collateral without
Secured Party's prior written consent; Debtor will do everything Secured Party
deems necessary or expedient to perfect or preserve the interests granted to
Secured Party under this Agreement and the first priority of such interests; any
Manufacturer's Statement or Certificate of Origin or Certificate of Title
relating to the Equipment shall be immediately delivered to Secured Party and,
if a Certificate of Title or registration is required for any item of Equipment;
Debtor will cooperate with Secured Party in obtaining the Certificate of Title
or registration disclosing the interests of Debtor and Secured Party in the
Equipment; Debtor will defend any action, proceeding or claim affecting the
Collateral or the interests of Secured Party in the Collateral; Debtor shall
promptly pay all amounts payable in conjunction with the storage, maintenance or
repair of the Equipment and all taxes, assessments, license fees and other
public or private charges levied or assessed in conjunction with the operation
or use of the Equipment or levied or assessed against the Collateral, this
Agreement or any accompanying note except for those which are being contested by
Debtor in good faith by appropriate proceedings and which do not constitute a
lien or encumbrance upon the Collateral; and Debtor will from time to time
furnish Secured Party with such financial statements and other information as
Secured Party may reasonably request.

3. INSURANCE AND RISK OF LOSS. Debtor shall at all times bear all risk of loss
of, damage to or destruction of the Equipment. Debtor agrees to immediately
procure and maintain insurance on the Equipment, for the full insurable value
thereof and for the life of this Agreement, in the form of "All Risk" or similar
insurance (insuring the Equipment for fire, extended coverage, vandalism, theft
and collision and containing only those exclusions from coverage which are
acceptable to Secured Party) plus such other insurance as Secured Party may
specify from time to time, all in form and amount and with insurers satisfactory
to Secured Party. Debtor agrees to deliver promptly to Secured Party
certificates or, if requested policies of insurance satisfactory to Secured
Party, each with a standard long-form loss-payable endorsement naming Secured
Party or assigns as loss-payee and providing that Secured Party's rights under
such policy will not be invalidated by any act, omission or neglect of anyone
other than Secured Party, and containing the insurer's agreement to give 30 days
prior written notice to Secured Party before any cancellation of or material
change in the policy(s) will be effective as to Secured Party, whether such
cancellation or change is at the direction of Debtor or insurer. Secured Party's
acceptance of policies in lesser amounts or risks will not be a waiver of
Debtor's obligation to procure insurance complying with the provisions hereof
promptly after notice from Secured Party. Debtor assigns to Secured Party all
proceeds of any physical damage or credit insurance for which a charge is stated
in this Agreement or which is maintained by Debtor in accordance herewith,
including returned and unearned premiums, up to the amount owing hereunder by
Debtor. Secured Party will not have the right to cancel any such insurance
without Debtor's consent prior to the occurrence of an event of default and the
repossession, loss or destruction of the Equipment. Debtor directs all insurers
to pay such proceeds solely to the order of Secured Party for application to
Debtor's indebtedness to Secured Party. Secured Party may, at its option, apply
any such proceeds received by Secured Party to the final maturing installments
due hereunder in the inverse order of their maturity.

4. PERFORMANCE BY SECURED PARTY. If Debtor fails to perform any of Debtor's
obligations pursuant to Paragraphs 1, 2, or 3 above, Secured Party may perform
the same for the account of Debtor. Any such action by Secured Party will be in
Secured Party's sole discretion and Secured Party will not be obligated in any
way to do so. Secured Party's performance on behalf of Debtor will not obligate
Secured Party to perform the same or any similar act in the future and will not
cure or waive Debtor's failure of performance as an event of default hereunder.
All sums advanced or costs and expenses incurred by Secured Party pursuant to
this Paragraph, including the reasonable fees of any attorney, retained by
Secured Party will be for the account of Debtor, will constitute indebtedness
secured by Secured Party's security interest in the Collateral, will bear
interest at the rate as specified on the reverse side of this Agreement in the
event of acceleration and, unless Secured Party, in Secured Party's sole
discretion agrees otherwise in writing, shall be immediately due and payable.

5. EVENTS OF DEFAULT. Time is of the essence. An event of default will occur if:
(a) Debtor fails to pay when due any amount owed by it to Secured Party or any
affiliate (including, without limitation, any direct or indirect parent,
subsidiary or sister entity), successor or assignee of Secured Party under this
Agreement or under the terms of any promissory note delivered in conjunction
with this Agreement or if Debtor fails to pay when due any amount owed by it to
Secured Party or any affiliate (including, without limitation, any direct or
indirect parent, subsidiary or sister entity), successor or assignee of Secured
Party under any other document, agreement or instrument; (b) Debtor fails to
perform in compliance with any of its agreements hereunder or any warranty made
by Debtor in this Agreement is or becomes incorrect, or if Debtor fails to
perform or observe any term or provision to be performed or observed by it under
any other document, instrument or agreement furnished by Debtor to Secured Party
or any affiliate (including, without limitation, any direct or indirect parent,
subsidiary or sister entity), successor or assignee of Secured Party or
otherwise acquired by Secured Party or any affiliate (including, without
limitation, any direct or indirect parent, subsidiary or sister entity),
successor or assignee of Secured Party; (c) any information, representation, or

6. REMEDIES UPON DEFAULT. Upon the occurrence of an event of default, and at any
time thereafter as long as the default continues, Secured Party may, at its
option, with or without notice to Debtor (i) declare this Agreement to be in
default, (ii) declare the indebtedness hereunder to be immediately due and
payable, (iii) declare all other debts then owing by Debtor to Secured Party or
any affiliate (including, without limitation, any direct or indirect parent,
subsidiary or sister entity), successor or assignee of Secured Party to
immediately due and payable, (iv) cancel any insurance and credit any refund to
the indebtedness, and (v) exercise all of the rights and remedies of a Secured
Party under the Uniform Commercial Code and any other applicable laws,
including, without limitation, the right to require Debtor to assemble the
Equipment and deliver it to Secured Party at a place to be designated by Secured
Party which is reasonably convenient to both parties, and to lawfully enter any
premises where the Collateral may be without judicial process and take
possession thereof. Acceleration of any or all indebtedness, if so elected by
Secured Party, shall be subject to all applicable laws including those
pertaining to refunds and rebates of unearned charges. Any property other than
the Collateral which is in or upon the Equipment at the time of repossession may
be taken and held without liability until its return is requested by Debtor. Any
sale or other disposition of any of the Equipment may be made at public or
private sale or through public auction at the option of Secured Party. Secured
Party may buy at any sale and become the owner of the Equipment. Unless
otherwise provided by law, any requirement of reasonable notice which Secured
Party may be obligated to give regarding the sale or other disposition of
Collateral will be met if such notice is given to Debtor at least ten days
before the time of sale or other disposition. Debtor agrees that Secured Party
may bring any legal proceedings it deems necessary to enforce the payment and
performance of Debtor's obligations hereunder in any court in the State shown in
Secured Party's address set forth herein, and service of process may be made
upon Debtor by mailing a copy of the summons to Debtor. All notices to Debtor
relating to this Agreement will be considered received when delivered in person
(including by facsimile transmission) or mailed to Debtor at the address of
Debtor contained in this Agreement or at any address later designated by Debtor
to Secured Party in writing. The filing by Secured Party of any action or
proceeding with respect to the Equipment or any of Debtor's obligations
hereunder shall not constitute an erection by Secured Party of Secured Party's
remedies or a waiver of Secured Party's rights to take possession of the
Equipment as provided above. Expenses of retaking, holding, preparing for sale,
selling and the like shall include (a) the reasonable fees of any attorneys
retained by Secured Party, (b) any amounts advanced or expenses incurred by
Secured Party pursuant to Paragraph 4 hereof and (c) all other legal and other
expenses incurred by Secured Party. Debtor agrees that it is liable for and will
promptly pay any deficiency resulting from any disposition of Collateral after
default and all costs and expenses, including the reasonable fees of any
attorney, incurred by Secured Party in the collection of any such deficiency.
Secured Party may sell the Equipment without giving any warranties as to the
Equipment. Secured Party may disclaim any warranties of title, possession, quiet
enjoyment, or the like. This procedure will not be considered to adversely
affect the commercial reasonableness of any sale of the Equipment.

7. POWER OF ATTORNEY. DEBTOR HEREBY APPOINTS SECURED PARTY OR ANY OFFICER,
EMPLOYEE OR DESIGNEE OF SECURED PARTY, OR ANY ASSIGNEE OF SECURED PARTY (OR ANY
DESIGNEE OF SUCH ASSIGNEE) AS DEBTOR'S ATTORNEY-IN-FACT TO. IN DEBTOR'S OR
SECURED PARTY'S NAME: (a) PREPARE, EXECUTE AND SUBMIT ANY NOTICE OR PROOF OF
LOSS IN ORDER TO REALIZE THE BENEFITS OF ANY INSURANCE POLICY INSURING THE
COLLATERAL; (b) PREPARE, EXECUTE AND FILE ANY AGREEMENT, DOCUMENT FINANCING
STATEMENT, INSTRUMENT (OR ANY OTHER WRITING OR RECORD) THAT, IN SECURED PARTY'S
OPINION IS NECESSARY TO PERFECT AND/OR GIVE PUBLIC NOTICE OF THE INTERESTS OF
SECURED PARTY IN ANY COLLATERAL THAT SECURES OR THAT MAY SECURE ANY OBLIGATIONS
OR INDEBTEDNESS OF DEBTOR TO SECURED PARTY; AND (c) ENDORSE DEBTOR'S NAME ON ANY
REMITTANCE REPRESENTING PROCEEDS OF ANY INSURANCE RELATING TO THE COLLATERAL OR
THE PROCEEDS OF THE SALE, LEASE OR OTHER DISPOSITION OF THE COLLATERAL (WHETHER
OR NOT THE SAME IS A DEFAULT HEREUNDER). This power is coupled with an interest
and is irrevocable so long as indebtedness remains unpaid from Debtor to Secured
Party. Debtor agrees to execute and deliver to Secured Party, upon Secured
Party's request, such documents, writings, records and assurances as Secured
Party deems necessary or advisable for the confirmation or perfection of the
security interest in Collateral and Secured Party's rights hereunder, including
such documents, writings, records and assurances as Secured Party may require
for filing or recording. Debtor authorizes Secured Party or any officer,
employee or designee of Secured Party or any assignee of Secured Party (or any
designee of such assignee) to file a financing statement describing the
Collateral. Debtor authorizes Secured Party or any officer, employee or designee
of Secured Party or any assignee of Secured Party (or any designee of such
assignee) to file financing statements covering assets of Debtor other than the
Collateral described herein.

8. ASSIGNMENT. Debtor shall not assign this Agreement without the prior written
consent of Secured Party. Secured Party or any assignee or successor of Secured
Party shall have the right to transfer, sell or assign all or any portion of
this Agreement or the indebtedness and/or obligations hereunder, without notice,
acknowledgement or consent from Debtor. Upon assignment, the term "Secured
Party" shall mean and refer to any assignee who is the holder of this Agreement.
The assignor will not be the assignee's agent for any purpose. Debtor waives and
will not assert against any assignee of Secured Party any claims, counterclaim,
claims in recoupment, abatement, reduction, defenses, or set-offs for breach of
warranty or for any other reason which Debtor could assert against Secured
Party, except defenses which cannot be waived under the Uniform Commercial Code.
Upon full payment of all obligations secured by this Agreement, the assignee may
deliver all original papers to the assignor for Debtor.

9. PRIVACY WAIVER. Secured Party may receive from and disclose to any
individual, corporation, business trust, association, company, partnership,
joint venture, or other entity (herein collectively, the "Entity"), including,
without limiting the generality of the foregoing, Secured Party's parent or any
affiliate or any subsidiary of Secured Party and any credit reporting agency or
other entity whether or not related to Secured Party for any purpose,
information about Debtor's accounts, credit application and credit experience
with Secured Party and Debtor authorizes any Entity to release to Secured Party
any information related to Debtor's accounts, credit experience and account
information regarding the Debtor. THIS SHALL BE CONTINUING AUTHORIZATION FOR ALL
PRESENT AND FUTURE DISCLOSURES OF DEBTOR'S ACCOUNT INFORMATION, CREDIT
APPLICATION AND CREDIT EXPERIENCE ON DEBTOR MADE BY SECURED PARTY, OR ANY ENTITY
REQUESTED TO RELEASE SUCH INFORMATION TO SECURED PARTY.

10. DEBIT TRANSACTIONS. Secured Party may but shall not be required to offer
Debtor the option of paying any of Debtor's obligations to Secured Party through
printed checks ("Debit Transactions") drawn pursuant to this authorization upon
Debtor's checking account, using Debtor's checking account number, bank routing
code and other information which Debtor provides to Secured Party prior to the
first Debit Transaction. Debtor authorizes Secured Party to initiate Debit
Transactions from Debtor's checking account in the amount necessary to pay the
installment payments, delinquency charges, or such other amounts as may now or
hereafter be due hereunder or under any other present or future agreement with
or which is held by Secured Party, plus a fee of ten dollars ($10.00) for each
Debit Transaction initiated by Secured Party. In the event applicable law
prohibits or restricts the amount of such fee, the fee chargeable under this
provision shall be limited and/or restricted in accordance with applicable law.
Secured Party may from time to time increase or decrease the Debit Transaction
fee upon prior written notice addressed to Debtor's last known address as shown
on the records of Secured Party and such increase or decrease shall be effective
as stated in the written notice. Unless prohibited by applicable law, Debtor's
continued use of Debit Transactions after the effective date specified in such
notice shall conclusively establish Debtor's agreement to pay the new Debit
Transaction fee stated therein. Debtor authorizes Secured Party or any officer,
employee or designee of Secured Party to endorse Debtor's name as drawer on any
printed check drawn in accordance with this authorization. Until cancelled by
Debtor, this authorization shall be valid for all Debit Transactions Secured
Party initiates in payment of Debtor's obligations hereunder or under any other
present or future agreement with or which is held by Secured Party. This
authorization may be canceled at any time by Debtor giving at least three (3)
business days prior written notice to Debtor's bank and Secured Party. Payment
by Debit Transactions is not required by Secured Party nor is its use a factor
in the approval of credit.

11. MISCELLANEOUS. (A) All of Secured Party's rights hereunder are cumulative
and not alternative. (B) The inclusion of a trade name or division name in the
identification of Debtor hereunder does not limit Secured Party's rights, after
the occurrence of an event of default, to proceed against all of Debtor's
assets, including those held or used by Debtor individually or under another
trade or division name. (C) If permitted by law, Debtor agrees that a carbon,
photographic or other reproduction of this Agreement or of a financing statement
may be filed as a financing statement. (D) Secured Party may correct patent
errors herein and fill in blanks. (E) All of the terms and provisions hereof
will apply to and be binding upon Debtor, its heirs, personal representatives,
successors and assigns and shall inure to the benefit of Secured Party, its
successors and assigns. (F) DEBTOR AND SECURED PARTY HEREBY WAIVE ANY RIGHT TO
TRIAL BY JURY IN ANY ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR THE
TRANSACTION CONTEMPLATED HEREBY. (G) DEBTOR HEREBY EXPRESSLY WAIVES NOTICE OF
NONPAYMENT, PRESENTMENT, PROTEST, DISHONOR, DEFAULT, INTENT TO ACCELERATE THE
MATURITY HEREOF AND OF ACCELERATION OF THE MATURITY HEREOF. (H) If allowed by
law, "the reasonable fees of attorneys" retained by Secured Party shall include
the amount of any flat fee, retainer, contingent fee and/or the hourly charges
of any attorney retained by Secured Party in enforcing any of Secured Party's
rights hereunder in the prosecution or defense of any litigation related to this
Agreement or the transactions contemplated by this Agreement. (I) To the extent
allowed by law, Debtor hereby waives any exemptions or appraisals. (J) No waiver
or change in this Agreement or in any related note will be binding upon Secured
Party, or Secured Party's assignee, unless such waiver or change is in writing
and signed by one of its officers and any such waiver or change shall then be
effective only upon the terms and to the extent provided in such writing. (K)
The acceptance by Secured Party of any remittance from a party other than Debtor
will in no way constitute Secured Party's consent to the transfer of any of the
Collateral to such party. (L) Any captions or headings included in this
Agreement are for convenience of reference only and shall not limit or otherwise
affect the meaning of any provision contained in this Agreement. (M) Any
provision contained herein which is contrary to, prohibited by or invalid under
applicable laws or regulations will be deemed inapplicable and omitted herefrom,
but shall not invalidate the remaining provisions hereof. (N) The only copy of
this Agreement which constitutes "chattel paper" is the original executed copy
designated as "Original for CitiCapital".
