5.3(j).

United States Federal law or Tennessee law permits the higher interest rate,
including to the extent permitted by applicable law, any amendments thereof
hereafter or any new law hereafter coming into effect to the extent that a
higher rate is permitted thereby. The Highest Lawful Rate shall be applied by
taking into account all amounts characterized by applicable law as interest on
indebtedness evidenced by the Notes, the Loan Documents (as amended and modified
hereby) or the Modification Loan Documents, so that the aggregate of all
interest does not exceed the maximum nonusurious amount permitted by applicable
law. It is the intent of Obligors, the Agent and each of the Lenders to conform
to and contract in strict compliance with applicable usury law from time to time
in effect. All agreements among Obligors, the Agent and/or any of the Lenders
(or any other party liable with respect to any indebtedness under the Loan
Documents or the Modification Loan Documents) are hereby limited by the
provisions of this Section which shall override and control all such agreements,
whether now existing or hereafter arising and whether written or oral (however,
reference to the term "oral" shall not be construed to modify or negate any



                                       9
<PAGE>   10

provisions hereof or of any other Loan Document or Modification Loan Document
regarding the absence or ineffectiveness of oral agreements). In no way, nor in
any event or contingency (including but not limited to prepayment, default,
demand for payment or acceleration of the maturity of any obligation), shall the
interest taken, reserved, contracted for, charged or received under this
Agreement, the Note, any of the other Loan Documents or the Modification Loan
Documents, any documents executed in connection with or relating to the
indebtedness or otherwise, or any documents evidencing any prior indebtedness
renewed, extended or modified by the Loan Documents or the Modification Loan
Documents, exceed the Highest Lawful Rate. If, from any possible construction of
any document, interest would otherwise be payable in excess of the Highest
Lawful Rate, any such construction shall be subject to the provisions of this
Section and such document shall be automatically reformed and the interest
payable shall be automatically reduced to the Highest Lawful Rate, without the
necessity of execution of any amendment or new document. If the Agent or any of
the Lenders shall ever receive anything of value which is characterized as
interest under applicable law and which would apart from this provision be in
excess of the Highest Lawful Rate (by reason of the allocation of interest among
any prior indebtedness which may have been extended, renewed and/or modified
pursuant to the Loan Documents or the Modification Loan Documents or by any
reason whatsoever), an amount equal to the amount which would have been
excessive interest shall, without penalty, be applied to the reduction of the
principal amount owing on the indebtedness in the inverse order of its maturity
and not to the payment of interest, or refunded to Obligors or the other payor
thereof if and to the extent such amount which would have been excessive exceeds
such unpaid principal. The right to accelerate maturity of the Notes or any
other indebtedness does not include the right to accelerate any interest which
has not otherwise accrued on the date of such acceleration, and neither the
Agent nor any of the Lenders intends to charge or receive any unearned interest
in the event of acceleration. All interest paid or agreed to be paid to the
Agent or any of the Lenders shall, to the extent permitted by applicable law, be
amortized, prorated, allocated and spread throughout the full stated term
(including any renewal or extension) of such indebtedness so that the amount of
interest on account of such indebtedness does not exceed the Highest Lawful
Rate. As used in this Section, the term "applicable law" shall mean the laws of
the State of Tennessee or the federal laws of the United States, whichever laws
allow the greater interest, as such laws now exist or may be changed or amended
or come into effect in the future. By execution of this Amendment, Obligors
acknowledge that they each believe the Notes, the Loan Documents and the
Modification Loan Documents to be nonusurious and agree that, if at any time,
any Obligor should have reason to believe that the Notes, the Loan Documents or
the Modification Loan Documents are in fact usurious, it shall give the Agent
written notice of its belief and the reasons why it believes the Note, the Loan
Documents or the Modification Loan Documents to be usurious, and each Obligor
agrees that the Agent shall have ninety (90) days following its receipt of such
written notice to make (or cause to be made) appropriate refund or other
adjustment in order to correct such condition if it in fact exists.

         12. NO THIRD PARTY RIGHTS OR OBLIGATIONS. No person or entity not a
party to or expressly identified by name in this Amendment as a beneficiary
under this Amendment shall have any third-party beneficiary or other rights
under this Amendment. Without limiting the foregoing, this Agreement shall not
affect or impair in any manner whatsoever any rights, claims, actions, demands
or causes of action which the Agent may have against either Obligor, the Hotel
Properties (including, without limitation the Additional Property) or any other
collateral for the indebtedness



                                       10
<PAGE>   11

evidenced by the Loan Documents (as amended and modified hereby) or the
Modification Loan Documents, or otherwise under or with respect to the Loan
Documents (as amended and modified hereby) or the Modification Loan Documents.

         13. CONTINUING VALIDITY. Except as expressly provided herein, all of
the terms, provisions, debts, duties, obligations, liabilities, representations
and warranties, rights, titles, security interests, liens, powers and privileges
existing by virtue of the Loan Documents (as amended and modified hereby) and
the Modification Loan Documents shall be and continue in full force and effect,
and are hereby acknowledged by each Obligor to be legal, valid, binding and
subsisting.

         14. APPLICABLE LAW. THIS AMENDMENT SHALL BE GOVERNED BY, AND CONSTRUED
IN ACCORDANCE WITH, THE LAWS OF THE STATE OF TENNESSEE AND THE LAWS OF THE
UNITED STATES APPLICABLE TO TRANSACTIONS WITHIN TENNESSEE.

         15. BINDING AGREEMENT. This Amendment shall be binding upon the parties
hereto and their respective heirs, personal representatives, successors and
assigns; provided, however, that the foregoing shall not be deemed or construed
to confer any right, title, benefit, cause of action or remedy upon any person
or entity not a party hereto, which such party would not or did not otherwise
possess.

         16. SEVERABILITY. This Amendment is intended to be performed in
accordance with, and only to the extent permitted by, all applicable laws and
court decisions. If any provision of this Amendment or the application thereof
to any person or circumstance shall, for any reason or to any extent, be invalid
or unenforceable, neither the remainder of this Amendment nor the application of
such provision to other persons or circumstances or other instruments referred
to in this Amendment shall be affected thereby, but rather the same shall be
enforced to the greatest extent permitted by law.

         17. MODIFICATION. Neither this Amendment nor any provision of this
Amendment may be waived, modified or amended except by an instrument in writing
signed by the party against which the enforcement of such waiver, modification
or amendment is sought, and then only to the extent set forth in such
instrument.

         18. NO PARTNERSHIP OR FIDUCIARY OBLIGATIONS. The Agent and Obligors
each expressly acknowledge and agree that the Agent has not formed, and is not
hereby forming, with any Obligor and/or any other party, a partnership, joint
venture or any other similar entity, and this Amendment is not intended, and
shall not be construed, to create any such entity or relationship. Furthermore,
the Agent and Obligors acknowledge and agree that the Agent has no fiduciary
obligations, of any type, with respect to any Obligor or any such party. IN NO
EVENT SHALL THE AGENT EVER BE LIABLE FOR ANY DEBTS, DUTIES OR OBLIGATIONS OF ANY
OBLIGOR OR WITH RESPECT TO THE HOTEL PROPERTIES (INCLUDING, WITHOUT LIMITATION,
THE ADDITIONAL PROPERTY) (UNLESS EXPRESSLY ASSUMED BY THE AGENT IN WRITING).

<PAGE>   12

         19. CONSTRUCTION. The terms, provisions and conditions of this
Amendment represent the results of negotiations between the Agent and Obligors,
each of whom has either represented itself or has been represented by counsel of
its own choosing, and none of whom has acted under duress or compulsion, whether
legal, economic or otherwise. Accordingly, the terms, provisions and conditions
of this Amendment shall be interpreted and construed in accordance with their
usual and customary meanings, and the Agent and Obligors, expressly, knowingly
and voluntarily, waive the application, in connection with the interpretation
and construction of this Amendment, of any rule of law or procedure to the
effect that ambiguous or conflicting terms, conditions or provisions shall be
interpreted or construed against the party whose attorney prepared the executed
version or any prior drafts of this Amendment.

         20. COOPERATION BY OBLIGORS. Upon request from the Agent, from time to
time, each Obligor will reasonably cooperate with and assist the Agent in
connection with the enforcement by the Agent of its rights and remedies under,
and the defense of any claims with respect to, the Loan Documents (as amended
and modified hereby) and the Modification Loan Documents. Obligors further agree
that, except for bona fide disputes arising after the date of this Amendment
based upon the conduct of the parties to this Amendment after the date of this
Amendment, they will not at any time challenge, contest or seek to set aside in
whole or in part the transactions provided in this Amendment.

         21. FURTHER ASSURANCES. In addition to the documents, instruments and
acts described in this Amendment and which are to be executed and/or delivered
and/or taken pursuant to this Agreement, Obligors agree to execute and deliver
from time to time upon request by the Agent such other documents and
instruments, and take such other action, as the Agent may reasonably request or
require to (i) more fully and completely evidence and carry out the transactions
contemplated by this Amendment, (ii) promptly correct any defect, error or
omission which may be discovered in this Amendment, the Loan Documents (as
amended and modified hereby) and the Modification Loan Documents, and execute
any and all additional documents, as may be requested by the Agent to correct
such defect, error or omission, (iii) create, perfect, preserve, maintain and
protect the liens and security interests created or intended to be created by
the Loan Documents (as amended and modified hereby) and the Modification Loan
Documents, and (iv) provide the rights and remedies to the Agent granted or
provided for by the Loan Documents (as amended and modified hereby) the
Modification Loan Documents, and this Amendment.

         22. ENTIRE AGREEMENT. This Amendment embodies and constitutes the
entire understanding between the Agent and Obligors with respect to the
transactions contemplated in this Amendment, and all prior or contemporaneous
agreements, understandings, representations and statements, oral or written, are
merged into this Amendment.

         23. HEADINGS. Descriptive headings are used in this Amendment for
convenience only and shall not control, limit, amplify or otherwise modify or
affect the terms and provisions of this Amendment or the meaning or construction
of the terms and provisions of this Amendment.

         24. TIME OF ESSENCE. Time is of the essence of this Amendment and of
each covenant and agreement that is to be performed at a particular time or
within a particular period of time. However, if the date or the final date of
any period which is set out in any provision of this



                                       12
<PAGE>   13

Amendment falls on a Saturday, Sunday or legal holiday under the laws of the
United States or the State of Texas, in such event, the date or the time of such
period shall be extended to the next date which is not a Saturday, Sunday or
legal holiday.

         25. ATTORNEYS' FEES. If it becomes necessary for the Agent and/or any
of the Lenders to file suit to enforce this Amendment or any Loan Document (as
amended and modified hereby) or any Modification Loan Document, or any provision
contained in this Amendment or any Loan Document (as amended and modified
hereby) or any Modification Loan Document, or to enforce any of its or their
rights in regard thereto or to otherwise incur legal and/or related expenses
concerning this Amendment, on demand from the Agent, and without limitation of
any other rights and remedies of the Agent and the Lenders, Obligors agree to
immediately reimburse the Agent and the Lenders for the attorneys' fees and
other costs incurred by the Agent and the Lenders.

         26. MULTIPLE COUNTERPARTS. This Amendment may be executed in a number
of identical counterparts, each of which for all purposes is deemed an original,
and all of which constitute collectively one Amendment, but in making proof of
this Amendment, it shall not be necessary to produce or account for more than
one such counterpart. In the event this Amendment is not executed by all of the
parties set forth herein, such fact shall not affect the binding effect of this
Amendment on those parties who have executed this Amendment, and those parties
who have executed this Amendment shall nevertheless be bound by all of the terms
and provisions contained herein.

         27. SOLE AGREEMENT. THIS WRITTEN AMENDMENT REPRESENTS THE FINAL
AGREEMENT BETWEEN THE AGENT AND OBLIGORS AND MAY NOT BE CONTRADICTED BY EVIDENCE
OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE AGENT AND
OBLIGORS. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE AGENT AND OBLIGORS.

         28. DEFINED TERMS. The defined terms utilized in this Amendment, unless
otherwise specifically defined herein, shall have the same meaning as the
meaning ascribed to such terms in the Fourth Restated Loan Agreement.

                      CONTINUING AND UNCONDITIONAL GUARANTY

         This CONTINUING AND UNCONDITIONAL GUARANTY (this "Guaranty") is
executed effective as of the 1st day of August, 2000, by PLANO INN, L.P., a
Texas limited partnership ("Guarantor"), to and in favor of BANK OF AMERICA,
N.A., a national banking association ("Bank of America"), and the other Lenders
who are parties to the Loan Agreement (collectively, the "Lender"s; Bank of
America and the Lenders are sometimes hereinafter collectively referred to as
"Bank")

1. GUARANTY. FOR VALUE RECEIVED, and to induce Bank to make loans or advances or
to extend credit or other financial accommodations or benefits, with or without
security, to or for the account of RFS Partnership, L.P., a Tennessee limited
partnership ("Borrower"), the undersigned "Guarantor", if more than one, then
each of them jointly and severally, hereby irrevocably and unconditionally
guarantees to Bank the full and prompt payment when due, whether by acceleration
or otherwise, of any and all Liabilities (as hereinafter defined) of Borrower to
Bank. This Guaranty is continuing and unlimited as to the amount, and is
cumulative to and does not supersede any other guaranties. All such capital
liabilities, fees, costs and expenses constitute the "Guaranty Obligations."

Guarantor further unconditionally guarantees the faithful, prompt and complete
compliance by Borrower with all Obligations (as hereinafter defined). The
undertakings of Guarantor hereunder are independent of the Liabilities and
Obligations of Borrower and a separate action or actions for payment, damages or
performance may be brought or prosecuted against Guarantor, whether or not an
action is brought against Borrower or to realize upon the security for the
Liabilities and/or Obligations, whether or not Borrower is joined in any such
action or actions, and whether or not notice is given or demand is made upon
Borrower.

Bank shall not be required to proceed first against Borrower, or any other
person or entity, whether primarily or secondarily liable, or against any
collateral held by it, before resorting to Guarantor for payment, and Guarantor
shall not be entitled to assert as a defense to the enforceability of the
Guaranty any defense of Borrower with respect to any Liabilities or Obligations.

2. PARAGRAPH HEADINGS, GOVERNING LAW AND BINDING EFFECT. Guarantor agrees that
the paragraph headings in this Guaranty are for convenience only and that they
will not limit any of the provisions of this Guaranty. Guarantor further agrees
that this Guaranty shall be governed by, and construed in accordance with, the
laws of the State of Tennessee. In any litigation in connection with or to
enforce this Guaranty or any other Loan Documents, Guarantor, and each of them,
irrevocably consent to and confer personal jurisdiction on the courts of the
State of Tennessee or the United States courts located within the State of
Tennessee. Nothing contained herein shall, however, prevent Bank from bringing
any action or exercising any rights within any other state or jurisdiction or
from obtaining personal jurisdiction by any other means available by applicable
law. This Guaranty is binding upon Guarantor, his, their or its executors,


<PAGE>   40
administrators, successors or assigns, and shall inure to the benefit of Bank,
its successors, indorsees or assigns. Anyone executing this Guaranty shall be
bound by the terms hereof without regard to execution by anyone else.

notice of any Liabilities or Obligations to which it may apply, presentment,
demand for payment, protest, notice of dishonor or nonpayment of any
Liabilities, notice of intent to accelerate, notice of acceleration, and notice
of any suit or the taking of other action by Bank against Borrower, Guarantor or
any other person, any applicable statute of limitations and any other notice to
any party liable on any Loan Document (including Guarantor).

Each Guarantor also hereby waives any claim, right or remedy which such
Guarantor may now have or hereafter acquire against Borrower that arises
hereunder and/or from the performance by any other Guarantor hereunder
including, without limitation, any claim, remedy or right of subrogation,
reimbursement, exoneration, contribution, indemnification or participation in
any claim, right or remedy of Bank against Borrower or against any security
which Bank now has or hereafter acquires, whether or not such claim, right or
remedy arises in equity, under contract, by statute, under common law or
otherwise.

Guarantor also waives the benefits of any provision of law requiring that Bank
exhaust any right or remedy, or take any action, against Borrower, any Guarantor
or any other person and/or property.

Bank may at any time and from time to time (whether before or after revocation
or termination of this Guaranty) without notice to Guarantor (except as required
by law), without incurring responsibility to Guarantor, without impairing,
releasing or otherwise affecting the Obligations of Guarantor, in whole or in
part, and without the indorsement or execution by Guarantor of any additional
consent, waiver or guaranty: (a) change the manner, place or terms of payment,
or change or extend the time of or renew, or change any interest rate or alter
any Liability or Obligation or installment thereof, or any security therefor;
(b) loan additional monies or extend additional credit to Borrower, with or
without security, thereby creating new Liabilities or Obligations the payment or
performance of which shall be guaranteed hereunder, and the Guaranty herein made
shall apply to the Liabilities and Obligations as so changed, extended,
surrendered, realized upon or otherwise altered; (c) sell, exchange, release,
surrender, realize upon or otherwise deal with in any manner and in any order
any property at any time pledged or mortgaged to secure the Liabilities or
Obligations and any offset there against; (d) exercise or refrain from
exercising any rights against Borrower or others (including Guarantor) or act or
refrain from acting in any other manner; (e) settle or compromise any Liability
or Obligation or any security therefor and subordinate the payment of all or any
part thereof to the payment of any


<PAGE>   42

Liability or Obligation of any other parties primarily or secondarily liable on
any of the Liabilities or Obligations; (f) release or compromise any Liability
of Guarantor hereunder or any Liability or Obligation of any other parties
primarily or secondarily liable on any of the Liabilities or Obligations; or (g)
apply any sums from any sources to any Liability without regard to any
Liabilities remaining unpaid.

5. SUBORDINATION. Guarantor agrees that it will not demand, take or receive from
Borrower, by set-off or in any other manner, payment of any debt, now and at any
time or times hereafter owing by Borrower to Guarantor unless and until all the
Liabilities and Obligations shall have been fully paid and performed, and any
security interest, liens or encumbrances which Guarantor now has and from time
to time hereafter may have upon any of the assets of Borrower shall be made
subordinate, junior and inferior and postponed in priority, operation and effect
to any security interest of Bank in such assets.

6. WAIVERS BY BANK. No delay on the part of Bank in exercising any of its
options, powers or rights, and no partial or single exercise thereof, shall
constitute a waiver thereof. No waiver of any of its rights hereunder, and no
modification or amendment of this Guaranty, shall be deemed to be made by Bank
unless the same shall be in writing, duly signed on behalf of Bank; and each
such waiver, if any, shall apply only with respect to the specific instance
involved, and shall in no way impair the rights of Bank or the obligations of
Guarantor to Bank in any other respect at any other time.

7. TERMINATION. This Guaranty shall be binding on each Guarantor until written
notice of revocation signed by such Guarantor or written notice of the death of
such Guarantor shall have been received by Bank, notwithstanding change in name,
location, composition or structure of, or the dissolution, termination or
increase, decrease or change in personnel, owners or partners of Borrower, or
any one or more of Guarantors. No notice of revocation or termination hereof
shall affect in any manner rights arising under this Guaranty with respect to
Liabilities or Obligations that shall have been committed, created, contracted,
assumed or incurred prior to receipt of such written notice pursuant to any
agreement entered into by Bank prior to receipt of such notice. The sole effect
of such notice of revocation or termination hereof shall be to exclude from this
Guaranty, Liabilities or Obligations thereafter arising that are unconnected
with Liabilities or Obligations theretofore arising or transactions entered into
theretofore.

8. PARTIAL INVALIDITY AND/OR ENFORCEABILITY OF GUARANTY. The unenforceability or
invalidity of any provision of this Guaranty shall not affect the enforceability
or validity of any other provision herein and the invalidity or unenforceability
of any provision of any Loan Document as it may apply to any person or
circumstance shall not affect the enforceability or validity of such provision
as it may apply to other persons or circumstances.

In the event Bank is required to relinquish or return the payments, the
collateral or the proceeds thereof, in whole or in part, which had been
previously applied to or retained for application against any Liability, by
reason of a proceeding arising under the Bankruptcy Code, or for any other
reason, this Guaranty shall automatically continue to be effective
notwithstanding any previous cancellation or release effected by Bank. This
Guaranty shall remain in full force and effect and continue to be effective
should any petition be filed by or against Borrower and/or


<PAGE>   43

Guarantor for liquidation or reorganization, should Borrower and/or Guarantor
become insolvent or make an assignment for the benefit of creditors or should a
receiver or trustee be appointed for all or any significant part of any of
Borrower's and/or Guarantor's assets, and shall, to the fullest extent permitted
by law, continue to be effective or be reinstated, as the case may be, if any
time, payment and performance of the Obligations and Liabilities, or any part
thereof, is, pursuant to applicable law, rescinded or reduced in amount, or must
otherwise be restored or returned by any obligee of the Obligations or
Liabilities or such part thereof, whether as a "voidable preference,"
"fraudulent transfer," or otherwise, all as though such payment or performance
had not been made. In the event that any payment, or any part thereof is
rescinded, reduced, restored or returned, the Obligations and Liabilities shall,
to the fullest extent permitted by law, be reinstated and deemed reduced only by
such amount paid and not so rescinded, reduced, restored or returned.

9. CHANGE OF STATUS. Guarantor will not become a party to a merger or
consolidation with any other company, or change its legal structure without the
written consent of Bank, except as may be expressly permitted in the Loan
Agreement; provided, however, that all covenants under this Guaranty shall be
assumed by the new or surviving entity. Guarantor further agrees that this
Guaranty shall be binding, legal and enforceable against Guarantor in the event
Borrower changes its name, status or type of entity.

10. FINANCIAL AND OTHER INFORMATION. Guarantor agrees to furnish to Bank any and
all financial information and any other information regarding Guarantor and/or
collateral requested in writing by Bank within ten (10) days of the date of the
request. Guarantor has made an independent investigation of the financial
condition and affairs of Borrower prior to entering into this Guaranty, and
Guarantor will continue to make such investigation; and in entering into this
Guaranty Guarantor has not relied upon any representation of Bank as to the
financial condition, operation or creditworthiness of Borrower. Guarantor
further agrees that Bank shall have no duty or responsibility now or hereafter
to make any investigation or appraisal of Borrower on behalf of Guarantor or to
provide Guarantor with any credit or other information which may come to its
attention now or hereafter.

11. NOTICES. Notice shall be deemed reasonable if mailed postage prepaid at
least five (5) days before the related action to the address of Guarantor or
Bank, at their respective addresses indicated below, or to such other address as
any party may designate by written notice to the other party. Each notice,
request and demand shall be deemed given or made, if sent by mail, upon the
earlier of the date of receipt or five (5) days after deposit in the U.S. Mail,
first class postage prepaid, or if sent by any other means, upon delivery.

13. REMEDIES. Upon the failure of Guarantor to fulfill its duty to pay
Liabilities and perform and satisfy all Obligations as required hereunder, Bank
shall have all of the remedies of a creditor and, to the extent applicable, of a
secured party, under all applicable laws, and without limiting the generality of
the foregoing, Bank may, at its option and without notice or demand: (a) declare
any Liability due and payable at once; (b) take possession of any collateral
pledged by


<PAGE>   45

Borrower or Guarantor wherever located, and sell, resell, assign, transfer and
deliver all or any part of said collateral of Borrower or Guarantor at any
public or private sale or otherwise dispose of any or all of the collateral in
its then condition, for cash or on credit or for future delivery, and in
connection therewith Bank may impose reasonable conditions upon any such sale,
and Bank, unless prohibited by law the provisions of which cannot be waived, may
purchase all or any part of said collateral to be sold, free from and discharged
of all trusts, claims, rights or redemption and equities of Borrower or
Guarantor whatsoever; Guarantor acknowledges and agrees that the sale of any
collateral through any nationally recognized broker-dealer, investment banker or
any other method common in the securities industry shall be deemed a
commercially reasonable sale under the Uniform Commercial Code or any other
equivalent statute or federal law, and expressly waives notice thereof except as
provided herein; and (c) set-off against any or all liabilities of Guarantor all
money owed by Bank or any of its agents or affiliates in any capacity to
Guarantor whether or not due, and also set-off against all other Liabilities of
Guarantor to Bank all money owed by Bank in any capacity to Guarantor, and if
exercised by Bank, Bank shall be deemed to have exercised such right of set-off
and to have made a charge against any such money immediately upon the occurrence
of such default although made or entered on the books subsequent thereto.

Bank shall have a properly perfected security interest in all of Guarantor's
funds on deposit with Bank to secure the balance of any Liabilities and/or
Obligations that Guarantor may now or in the future owe Bank. Bank is granted a
contractual right of set-off and will not be liable for dishonoring checks or
withdrawals where the exercise of Bank's contractual right of set-off or
security interest results in insufficient funds in Guarantor's account. As
authorized by law, Guarantor grants to Bank this contractual right of set-off
and security interest in all property of Guarantor now or at anytime hereafter
in the possession of Bank, including but not limited to any joint account,
special account, account by the entireties, tenancy in common, and all dividends
and distributions now or hereafter in the possession or control of Bank.

14. ATTORNEY FEES, COST AND EXPENSES. Guarantor shall pay all costs of
collection and reasonable attorney's fees, including reasonable attorney's fees
in connection with any suit, mediation or arbitration proceeding, out of court
payment agreement, trial, appeal, bankruptcy proceedings or otherwise, incurred
or paid by Bank in (a) defending this Guaranty or (b) enforcing the payment or
performance of any Liability or Obligation.

15. COLLATERAL. Bank at all times and from time to time shall have the right to
require Guarantor to deliver to Bank collateral satisfactory to Bank to secure
Guarantor's undertakings hereunder and/or the Liabilities or Obligations of
Guarantor hereunder.

16. PRESERVATION OF PROPERTY. Bank shall not be bound to take any steps
necessary to preserve any rights in any property pledged as collateral to Bank
to secure Borrower and/or Guarantor's Liabilities and Obligations as against
prior parties who may be liable in connection therewith, and Borrower and
Guarantor hereby agree to take any such steps. Bank, nevertheless, at any time,
may (a) take any action it deems appropriate for the care or preservation of
such property or of any rights of Borrower and/or Guarantor or Bank therein; (b)
demand, sue for, collect or receive any money or property at any time due,
payable or receivable on account of or in exchange for any property pledged as
collateral to Bank to secure Borrower and/or Guarantor's


<PAGE>   46

Liabilities to Bank; (c) compromise and settle with any person liable on such
property; or (d) extend the time of payment or otherwise change the terms of the
Loan Documents as to any party liable on the Loan Documents, all without notice
to, without incurring responsibility to, and without affecting any of the
Obligations or Liabilities of Guarantor.

INCLUDING BUT NOT LIMITED TO THOSE ARISING OUT OF OR RELATING TO THIS
INSTRUMENT, AGREEMENT OR DOCUMENT OR ANY RELATED INSTRUMENTS, AGREEMENTS OR

Guaranty subject to avoidance under Sections 544, 548 or 550 of the Federal
Bankruptcy Code or subject to being set aside or annulled under any applicable
state law relating to fraud on creditors; provided, however, that, for purposes
of the immediately preceding clause, it shall be presumed that the Guaranteed
Obligations of Guarantor under this Guaranty do not equal or exceed any
aggregate amount which would render Guarantor's indebtedness, liabilities or
obligations under this Guaranty subject to being so avoided, set aside or
annulled, and the burden of proof to the contrary shall be on the party
asserting to the contrary. Subject to but without limiting the generality of the
foregoing sentence, the provisions of this Guaranty are severable and, in any
legally binding action or proceeding involving any state corporate law or any
bankruptcy, insolvency or other laws of general application relating to the
enforcement of creditors' rights and general principles of equity, if the
indebtedness, liabilities or obligations of Guarantor under this Guaranty would
otherwise be held or determined to be void, invalid or unenforceable on account
of the amount of its indebtedness, liabilities or obligations under this
Guaranty, then, notwithstanding any other provision of this Guaranty to the
contrary, the amount of such indebtedness, liabilities or obligations shall,
without any further action by Guarantor, Bank or any other Person, be
automatically limited and reduced to the greatest amount which is valid and
enforceable as determined in such action or proceeding.
