| | Compliance
 with Governmental Requirements. Comply with all laws, ordinances, and regulations, now or hereafter
 in effect, of all governmental authorities applicable to the conduct of
 Borrowers properties, businesses and operations, and to the use or occupancy
 of the Collateral, including without limitation, the Americans With
 Disabilities Act. Borrower may contest in good faith any such law, ordinance,
 or regulation and withhold compliance during any proceeding, including
 appropriate appeals, so long as Borrower has notified Lender in writing prior
 to doing so and so long as, in Lenders sole opinion, Lenders interests in
 the Collateral are not jeopardized. Lender may require Borrower to post
 adequate security or a surety bond, reasonably satisfactory to Lender, to
 protect Lenders interest.

| | Inspection. Permit employees or agents of Lender at any
 reasonable time to inspect any and all Collateral for the Loan or Loans and
 Borrowers other properties and to examine or audit Borrowers books,
 accounts, and records and to make copies and memoranda of Borrowers books,
 accounts, and records. If Borrower now or at any time hereafter maintains any
 records (including without limitation computer generated records and computer
 software programs for the generation of such records) in the possession of a
 third party, Borrower, upon request of Lender, shall notify such party to
 permit Lender free access to such records at all reasonable times and to
 provide Lender with copies of any records it may request, all at Borrowers
 expense.                                                               

LENDERS EXPENDITURES. If any action or proceeding is commenced that
would materially affect Lenders interest in the Collateral or if Borrower
fails to comply with any provision of this Agreement or any Related Documents,
including but not limited to Borrowers failure to discharge or pay when due
any amounts Borrower is required
to discharge or pay under this Agreement or any Related Documents, Lender on
Borrowers behalf may (but shall not be obligated to) take any action that
Lender deems appropriate on any Collateral and paying all costs for insuring,
maintaining and preserving any 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 Borrower. 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.

CESSATION OF ADVANCES. If Lender has made any commitment to make any
Loan to Borrower, whether under this Agreement or under any other agreement,
Lender shall have no obligation to make Loan advances or to disburse Loan
proceeds if: (A) Borrower or any guarantor is in default under the terms of
this Agreement or any other agreement that Borrower or any guarantor has with
Lender; (B) Borrower or any guarantor dies, becomes incompetent or becomes insolvent,
files a petition in bankruptcy or similar proceedings, or is adjudged a
bankrupt; (C) there occurs a material adverse change in Borrowers financial
condition, in the financial condition of any guarantor, or in the value of any
collateral securing any Loan; or (D) any guarantor seeks, claims or otherwise
attempts to limit, modify or revoke such guarantors guaranty of the Loan or
any other loan with Lender; or (E) Lender in good faith deems itself insecure,
even though no Event of Default shall have occurred.

RIGHT OF SETOFF. To the extent permitted by applicable law, Lender reserves a right of
setoff in all Borrowers accounts with Lender (whether checking, savings, or
some other account). This includes all accounts Borrower holds jointly with
someone else and all accounts Borrower may open in the future. However, this
does not include any IRA or Keogh accounts, or any trust accounts for which
setoff would be prohibited by law. Borrower authorizes Lender, to the extent
permitted by applicable law, to charge or setoff all sums owing on the
Indebtedness against any and 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.

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

of any kind to Borrower,
except that in the case of an Event of Default of the type described in the
Insolvency subsection above, such acceleration shall be automatic and not
optional. In addition, Lender shall have all the rights and remedies provided
in the Related Documents or available at law, in equity, or otherwise. Except
as may be prohibited by applicable law, all of Lenders rights and remedies
shall be cumulative and may be exercised singularly or concurrently. Election
by Lender to pursue any remedy shall not exclude pursuit of any other remedy,
and an election to make expenditures or to take action to perform an obligation
of Borrower or of any Grantor shall not affect Lenders right to declare a
default and to exercise its rights and remedies.

FACSIMILE AND COUNTERPART. This document may be signed in any number of
separate copies, each of which shall be effective as an original, but all of
which taken together shall constitute a single document. An electronic
transmission or other facsimile of this document or any related document shall
be deemed an original and shall be admissible as evidence of the document and
the signers execution.

ADDITIONAL SECURITY. Notwithstanding anything to the contrary in this or any related
agreement, to further secure the indebtedness and obligations of the Note and
related loan documents, Borrower pledges and grants to Lender a security
interest in Borrowers accounts with Lender, including without limitation,
checking, savings, investment, general and special accounts, and accounts held
for safekeeping, held jointly with others, and accounts opened in the future,
excluding however all IRAs, Keogh accounts, and trust accounts to the extent a
security interest would be invalid or prohibited by law.

INSURANCE. Borrower shall assure that insurance is maintained pursuant to any
insurance requirements set forth in the Agreement To Provide Insurance and /or
other Related Documents, if applicable.

ARBITRATION AGREEMENT. Arbitration - Binding Arbitration. Lender and
each 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, Regional Banking, or any successor group or department
of Lender. 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 AAA (American Arbitration Association), or such other
administrator as the parties shall mutually agree upon, in accordance with the
AAAs commercial dispute resolution procedures, unless the claim or
counterclaim is at least $1,000,000.00 exclusive of claimed interest,
arbitration fees and 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) foreclose against 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 any party 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 all three 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 any arbitration proceeding
within 180 days of the filing of the Dispute with the AAA. The resolution of
any Dispute shall be determined by a separate 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.

State-Specific Provisions.

specifically elects in writing to proceed with the arbitration, or (ii) all
parties to the arbitration waive any rights or benefits that might accrue to
them by virtue of the single action rule statute of Nevada, thereby agreeing

specifically elects in writing to proceed with the arbitration. If any such
Dispute is not submitted to arbitration, the Dispute shall, at the election of

Procedure 53, and this general reference agreement is intended to be
specifically enforceable. A master with the qualifications required herein for
arbitrators shall be selected pursuant to the AAAs selection procedures.
Judgment upon the decision rendered by a master shall be entered in the court
in which such proceeding was commenced in accordance with Utah Rule of Civil
Procedure 53(e).

Banking Group, or its successors (Excluded Loans). These covenants supersede
and replace any prior financial reporting and condition covenants and shall
