 interest in and to all computer software required to utilize, create, maintain, and process any such records
 or data on electronic media.

Despite any other provision of this Agreement, Lender is not granted, and
will not have, a nonpurchase money security interest in household goods, to the extent such a security interest would be
prohibited by
applicable law. In addition, if because of the type of any Property, Lenderis required to give a notice of the
right to cancel under Truth in
Lending for the Indebtedness, then Lender will not have a security interest insuch
Collateral unless and until such a notice is given.

CROSS-COLLATERALIZATION.In addition to the Note, this Agreement secures all
obligations, debts
and liabilities, plus interest thereon, ofGrantor
to Lender, or any one or more of them, as well as all claims by Lender against
Grantor or any one or more of them, whether nowexisting
or hereafter arising, whether related or unrelated to the purpose of the Note,
whether voluntary or otherwise, whether due or not due,direct or
indirect, determined or undetermined, absolute or contingent, liquidated or
unliquidated whether Grantor may be liable individually or jointly with others, whether obligated as
guarantor, surety, accommodation party or otherwise, and whether recovery upon
such amounts may be or hereafter may
become barred by any statute of limitations, and whether the obligation to
repay such amounts may be or hereafter may become otherwise
unenforceable.

RIGHT OF SETOFF.To
the extent permitted by applicable law, Lender reserves a right of setoff in
all Grantors accounts with Lender (whetherchecking,
savings, or some other account). This includes all accounts Grantor holds
jointly with someone else and all accounts Grantor mayopen in the future. However, this does not include any IRA
or Keogh
accounts, or any trust accounts for which setoff would be prohibited bylaw. Grantor authorizes Lender, to the
extent permitted by applicable
law, to charge or setoff all sums owing on the Indebtedness against anyand all such
accounts, and, at Lenders option, to administratively freeze all such accounts
to allow Lender to protect Lenders charge and setoff rights provided in this paragraph.

GRANTORS REPRESENTATIONS AND WARRANTIES WITH RESPECT
TO THE COLLATERAL.With respect to the Collateral,
Grantor representsand promises to Lender that:

| | Perfection of Security Interest.Grantor agrees to execute financing statements and to take whatever other
actions are requested by Lender to

request of Lender, Grantor will deliver to Lender any and all of the
documents evidencing or constituting the Collateral, and Grantor will note
Lenders interest upon any and all chattel paper if not delivered to Lender
for possession by Lender. This is a continuing Security Agreement and will
continue in effect even though all or any part of the Indebtedness is paid in
full and even though for a period of time Grantor may not be indebted to
Lender.

 shall not sell, offer to sell, or otherwise transfer or dispose of the
 Collateral. WhileGrantor is not in default under
 this Agreement, Grantor may sell inventory, but only in the ordinary course
 of its business and only to buyerswho qualify as a buyer in

 business does not include a transfer in partial
 or total satisfaction of a debt or any bulk sale. Grantor shall not pledge,
 mortgage, encumber or otherwise permit the Collateral to be subject to any
 lien, security interest, encumbrance, or charge, other than the security
 interest provided for in this Agreement, without the prior written consent of

 security interests granted under this Agreement. Unless waived by Lender, all proceeds from any disposition
 of the Collateral (for whatever reason) shall be held in trust for Lender and shall not be commingled with any other
 funds; provided however, this requirement shall not constitute consent by Lender
 to any sale or other disposition. Upon receipt, Grantor shall
 immediately deliver any such proceeds to Lender.

| | Maintenance of Casualty Insurance.Grantor shall procure and maintain all risks insurance, including without
 limitation fire, theft andliability coverage
 together with such other insurance as Lender may require with respect to the
 Collateral, in form, amounts, coverages and basis
 reasonably acceptable to Lender and issued by a company or companies
 reasonably acceptable to Lender. Grantor, upon request of Lender, will deliver to Lender from time to time
 the policies or certificates of insurance in form satisfactory to Lender,
 including stipulations that
 coverages will not be cancelled or diminished without at least ten (10) days
 prior written notice to Lender and not including any disclaimer of the insurers liability for failure
 to give such a notice. Each insurance policy also shall include an
 endorsement providing that coverage
 in favor of Lender will not be impaired in any way by any act, omission or
 default of Grantor or any other person. In connection with all policies
 covering assets in which Lender holds or is offered a security
 interest, Grantor will provide Lender with such loss payable or other endorsements as Lender may require. If
 Grantor at any time fails to obtain or maintain any insurance as required
 under this Agreement, Lender may (but shall not be obligated to)
 obtain such insurance as Lender deems appropriate, including if Lender so
 chooses single interest insurance, which will cover only Lenders interest
 in the Collateral.

 within fifteen (15) days of the casualty. All proceeds of any insurance on
 the Collateral, including accrued proceeds
 thereon, shall be held by Lender as part of the Collateral. If Lender
 consents to repair or replacement of the damaged or destroyed Collateral, Lender shall, upon
 satisfactory proof of expenditure, pay or reimburse Grantor from the proceeds
 for the reasonable cost of repair or restoration. If Lender does not
 consent to repair or replacement of the Collateral, Lender shall retain a
 sufficient amount of the proceeds to pay
 all of the Indebtedness, and shall pay the balance to Grantor. Any proceeds

| | Insurance Reserves.Lender may require Grantor to maintain with Lender reserves for payment of
 insurance premiums, which reserves shallbe
 created by monthly payments from Grantor of a sum estimated by Lender to be
 sufficient to produce, at least fifteen (15) days beforethe
 premium due date, amounts at least equal to the insurance premiums to be
 paid. If fifteen (15) days before payment is due, the reserve funds are insufficient, Grantor shall upon demand
 pay any deficiency to Lender. The reserve funds shall be held by Lender as a
 general deposit and shall constitute a non-interest-bearing account
 which Lender may satisfy by payment of the insurance premiums required to be paid by Grantor as they become due. Lender does
 not hold the reserve funds in trust for Grantor, and Lender is not the agent
 of Grantor for payment of the insurance premiums required to be paid by
 Grantor. The responsibility for the payment of premiums shall remain Grantors
 sole responsibility.

 Reports.Grantor, upon request of Lender, shall furnish to
 Lender reports on each existing policy of insurance showing such information as Lender may reasonably request
 including the following: (1) the name of the insurer; (2) the risks insured;
 (3) the amount of the policy; (4) the property insured; (5) the then
 current value on the basis of which insurance has been obtained and the
 manner of determining that value; and (6)
 the expiration date of the policy. In addition, Grantor shall upon request by
 Lender (however not more often than
 annually) have an independent appraiser satisfactory to Lender determine, as
 applicable, the cash value or replacement cost of the Collateral.

otherwise provided below with respect toaccounts, Grantor may have possession of the tangible personal property
and beneficial use of all the Collateral and may use it in any lawfulmanner not
inconsistent with this Agreement or the Related Documents, provided that
Grantors right to possession and beneficial use shall not apply to any Collateral where possession of the
Collateral by Lender is required by law to perfect Lenders security interest
in such Collateral. Until otherwise notified by Lender, Grantor may
collect any of the Collateral consisting of accounts. At any time and even
though no Event of Default exists, Lender may
exercise its rights to collect the accounts and to notify account debtors to
make payments directly to Lender for application to the Indebtedness. If
Lender at any time has possession of any Collateral, whether before or after an
Event of Default, Lender shall be deemed to
have exercised reasonable care in the custody and preservation of the
Collateral if Lender takes such action for that purpose as Grantor shall
request or as Lender, in Lenders sole discretion, shall deem appropriate under
the circumstances, but failure to honor any request by Grantor shall not
of itself be deemed to be a failure to exercise reasonable care. Lender shall
not be required to take any steps necessary to preserve any rights in the Collateral against prior parties, nor to
protect, preserve or maintain any security interest given to secure the
Indebtedness.

LENDERS EXPENDITURES.If any action or proceeding
is commenced that would materially affect Lenders interest in the Collateral
or if Grantor fails to comply with any
provision of this Agreement or any Related Documents, including but not limited
to Grantors failure to discharge or pay when due any amounts Grantor is
required to discharge or pay under this Agreement or any Related Documents,
Lender on Grantors behalf may (but shall not
be obligated to) take any action that Lender deems appropriate, including but
not limited to discharging or paying
all taxes, liens, security interests, encumbrances and other claims, at any
time levied or placed on the Collateral and paying all costs for insuring,
maintaining and preserving the Collateral. All such expenditures incurred or
paid by Lender for such purposes will then bear interest at the rate charged
under the Note from the date incurred or paid by Lender to the date of
repayment by Grantor. All such expenses will become a part of the Indebtedness and, at Lenders option, will (A) be payable on
demand; (B) be added to the balance of the Note and be apportioned among
and be payable with any installment payments to become due during either (1)
the term of any applicable insurance policy; or (2) the remaining term of the Note; or (C) be treated as a balloon payment which
will be due and
payable at the Notes maturity. The Agreement also will secure payment of these
amounts. Such right shall be in addition to all other rights and remedies to
which Lender may be entitled upon Default.

DEFAULT.Each
of the following shall constitute an Event of Default under this Agreement:

the Collateral or proceeds thereof in Lenders own name or that of Grantor. Lender may sell the
Collateral at public auction or private sale. Unless the Collateral threatens
to decline speedily in value or is of a
type customarily sold on a recognized
market, Lender will give Grantor, and other persons as required by law, reasonable
notice of the time and place of any public sale, or the time after which any
private sale or any other disposition of the Collateral is to be made. However, no notice need be
provided to any person who, after Event of Default occurs, enters into and
authenticates an agreement waiving that persons right to notification of sale.
The requirements of reasonable notice shall be met if such notice is given at
least ten (105) days before the time of the sale or disposition. All
expenses relating to the disposition of the Collateral, including without limitation the expenses of retaking, holding,
insuring, preparing for sale and selling the Collateral, shall become a part
of the Indebtedness secured by this

 shall have the right to have a receiver appointed to take possession of all
 or any part of the Collateral, with the power
 to protect and preserve the Collateral, to operate the Collateral preceding
 foreclosure or sale, and to collect the Rents from the Collateral and apply the proceeds, over and above
 the cost of the receivership, against the Indebtedness. The receiver may
 serve without bond if permitted by law. Lenders right to the appointment of
 a receiver shall exist whether or not the apparent value of the Collateral
 exceeds the Indebtedness by a substantial amount. Employment by Lender shall
 not disqualify a person from serving as a receiver.

 Revenues, Apply Accounts.Lender, either itself or
 through a receiver, may collect the payments, rents, income, and revenues
 from the Collateral. Lender may at any time
 in Lenders discretion transfer any Collateral into Lenders own name or that
 of Lenders nominee and receive the
 payments, rents, income, and revenues therefrom and hold the same as security
 for the Indebtedness or apply it to payment
 of the Indebtedness in such order of preference as Lender may determine.
 Insofar as the Collateral consists of accounts, general intangibles,
 insurance policies, instruments, chattel paper, choses in action, or similar
 property, Lender may demand, collect, receipt for, settle, compromise, adjust, sue for, foreclose, or realize on the
 Collateral as Lender may determine, whether or not Indebtedness or Collateral
 is then due. For these purposes, Lender may, on behalf of and in the name of
 Grantor, receive, open and dispose of mail addressed to Grantor; change any address to which mail and payments are
 to be sent; and endorse notes, checks, drafts, money orders, documents of title, instruments and items
 pertaining to payment, shipment, or storage of any Collateral. To facilitate
 collection, Lender may notify account debtors and obligors on any
 Collateral to make payments directly to Lender.

ARBITRATION.

Binding Arbitration.Lender, Borrower, and every
other party to this agreement hereby agree, upon demand by any party, to submit
any Dispute to binding arbitration in
accordance with the terms of this Arbitration Program. A Dispute shall
include any dispute, claim or controversy of any kind, whether in contract or in tort, legal or equitable, now
existing or hereafter arising, relating in any way to this Agreement or any
related agreement incorporating this
Arbitration Program (the Documents), or any past, present, or future loans,
transactions, contracts, agreements, relationships, incidents or injuries of
any kind whatsoever relating to or involving Business Banking, Community
Banking, or any successor group or
department of Bank. DISPUTES SUBMITTED TO ARBITRATION ARE NOT RESOLVED IN COURT
BY A JUDGE OR JURY.

Governing Rules.Any
arbitration proceeding will (i)be governed by the Federal Arbitration Act (Title 9
of the United States
Code),notwithstanding any conflicting choice of law provision in
any of the documents between the parties; and (ii)
be conducted by the American Arbitration
Association (AAA), or such other administrator as the parties shall mutually
agree upon, in accordance with the AAAs commercial dispute resolution procedures, unless the claim ofcounterclaim is at

costs in
which case the arbitration shall be conducted in accordance with the AAAs
optional procedures for large, complex commercial disputes (the commercial
dispute resolution procedures or the optional procedures for large, complex
commercial disputes to be referred to, as applicable, as the Rules). If there
is any inconsistency between the terms hereof and the Rules, the terms and
procedures set forth herein shall control. Arbitration proceedings hereunder
shall be conducted at a location mutually agreeable to the parties, or if they
cannot agree, then at a location selected by the AAA in the state of the
applicable substantive law primarily governing the Credit. Any party who fails
or refuses to submit to arbitration
following a demand by any other party shall bear all costs and expenses
incurred by such other party in compelling arbitration of any Dispute. Arbitration may be demanded at any time,
and may be compelled by summary proceedings in Court. The institution and
maintenance of an action for judicial
relief or pursuit of a provisional or ancillary remedy shall not constitute a
waiver of the right of any party, including the plaintiff, to submit the
controversy or claim to arbitration if any other party contests such action for
judicial relief. The arbitrator shall award all costs and expenses of
the arbitration proceeding. Nothing contained herein shall be deemed to be a
waiver by any party that is a bank of the protections afforded to it under 12
U.S.C. °91 or any similar applicable state law.

No Waiver of Provisional Remedies, Self-Help and
Foreclosure.The arbitration requirement does
not limit the right of any party to (i) forecloseagainst real or personal property collateral; (ii) exercise
self-help
remedies relating to collateral or proceeds of collateral such as setoff or
repossession; or (iii) obtain provisional or ancillary remedies such as
replevin, injunctive relief, attachment or the appointment of a receiver,
before during or after the pendency of any arbitration proceeding. This
exclusion does not constitute a waiver of the right or obligation of anyparty to
submit any Dispute to arbitration or reference hereunder, including those
arising from the exercise of the actions detailed in sections (i), (ii) and
(iii) of this paragraph.

Arbitrator Qualifications and Powers.Any arbitration proceeding in which the
amount in controversy is
$5,000,000.00 or less will be decided by a single arbitrator selected according
to the Rules, and who shall not render an award of greater than $5,000,000.00.
Any Dispute in which the amount in controversy exceeds $5,000,000.00 shall be
decided by majority vote of a panel of three arbitrators; provided however,
that allthree arbitrators must actively participate in all hearings
and deliberations. Every arbitrator must be a practicing attorney or a retired
member of the state or federal judiciary, in
either case with a minimum of ten years experience in the substantive law
applicable to the subject matter of the Dispute. The arbitrator will
determine whether or not an issue is arbitratable and will give effect to the
statutes of limitation in determining any claim.
In any arbitration proceeding the arbitrator will decide (by documents only or
with a hearing at the arbitrators discretion) any pre-hearing motions which
are similar to motions to dismiss for failure to state a claim or motions for
summary adjudication. The arbitrator shall resolve all Disputes in accordance with the applicable
substantive law and may grant any remedy or relief that a court of such state
could order or grant within the scope
hereof and such ancillary relief as is necessary to make effective any award.
The arbitrator shall also have the power to award recovery of all costs and fees, to impose
sanctions and to take such other action as the arbitrator deems necessary to
the same extent a judge could pursuant
to the Federal Rules of Civil Procedure, the applicable State Rules of Civil
Procedure, or other applicable law. Judgment upon the award rendered by
the arbitrator may be entered in any court having jurisdiction.

Discovery.In any arbitration proceeding discovery will be
permitted in accordance with the Rules. All discovery shall be expressly
limited to matters directly relevant to the
Dispute being arbitrated and must be completed no later than 20 days before the
hearing date and within 180 days of
the filing of the Dispute with the AAA. Any requests for an extension of the
discovery periods, or any discovery disputes, will be subject to final determination by the arbitrator
upon a showing that the request for discovery is essential for the partys
presentation and that no alternative means for obtaining information is
available.

Miscellaneous.To the
maximum extent practicable, the AAA, the arbitrators and the parties shall take
all action required to conclude anyarbitration
proceeding within 180 days of the filing of the Dispute with the AAA. The
resolution of any Dispute shall be determined by aseparate
arbitration proceeding and such Dispute shall not be consolidated with other
disputes or included in any class proceeding. No arbitrator or other party to
an arbitration proceeding may disclose the existence, content or results
thereof, except for disclosures of information by a party required in the
ordinary course of its business or by applicable law or regulation. If more
than one agreement for arbitration by or between the parties potentially applies to a Dispute, the arbitration provision
most directly related to the documents between the parties or the subject matter of the Dispute shall control. This
arbitration provision shall survive termination, amendment or expiration of any
of the documents or any relationship
between the parties.

| | No Waiver by Lender.Lender shall not be deemed to have waived any rights under this Agreement
unless such waiver is given in writing and signed by Lender. No delay
or omission on the part of Lender in exercising any right shall operate as a
waiver of such right or any other right. A waiver by Lender of a provision of
this Agreement shall not prejudice or constitute a waiver of Lenders right
otherwise to demand strict compliance with
that provision or any other provision of this Agreement. No prior waiver by
Lender, nor any course of dealing
between Lender and Grantor, shall constitute a waiver of any of Lenders
rights or of any of Grantors obligations as to any future transactions. Whenever the consent of
Lender is required
under this Agreement, the granting of such consent by Lender in any instance shall not constitute
continuing consent to subsequent
instances where such consent is required
and in all cases such consent may be granted or withheld in the
sole discretion of Lender.
