                               GUARANTY AGREEMENT

         FOR VALUE RECEIVED, and in consideration of credit given or to be

to time afforded or to be afforded to SUSA PARTNERSHIP, L.P., a Tennessee
limited partnership whose address is 175 Toyota Plaza, Suite 700, Memphis,
Tennessee 38103 (hereinafter called the "Debtor"), by FIRST TENNESSEE BANK
NATIONAL ASSOCIATION, a national banking association organized and existing
under the laws of the United States, and having a place of business in Memphis,
Tennessee (hereinafter called the "Bank"), the undersigned STORAGE USA, INC., a
Tennessee corporation whose address is 175 Toyota Plaza, Suite 700, Memphis,
Tennessee 38103, and STORAGE USA TRUST, a Maryland business trust whose address
is 175 Toyota Plaza, Suite 700, Memphis, Tennessee 38103 (hereinafter
collectively the "Guarantor") hereby jointly and severally (if more than one),
for themselves, their heirs, executors, administrators and successors absolutely
and unconditionally guarantee(s) the full and prompt payment to the Bank, at
maturity (whether by acceleration or otherwise) and at all times thereafter, of
each and all of the following:

                  1. the indebtedness (and interest thereon) evidenced by that
         certain Second Amended and Restated Revolving Credit Note (the "Note"),
         bearing date of the 16th day of October, 2001, in the principal sum of
         Forty Million Dollars ($40,000,000.00), bearing interest from date at
         the rate specified in said Note, said Note being payable to the order
         of the Bank, at the offices of the Bank at 165 Madison Avenue, Memphis,
         Tennessee 38103, or at such other place as the holder may designate in
         writing, being executed by the Debtor, and being given for value
         received, said Note being incorporated herein by reference as fully and
         particularly as if set out verbatim herein, said Note being an
         amendment and restatement of an Amended and Restated Revolving Credit
         Note in the principal amount of Forty Million Dollars ($40,000,000.00),
         dated May 4, 1998, executed by the Debtor and payable to Bank, which to
         the extent of Fifteen Million Dollars ($15,000,000.00), amended and
         restated a Revolving Credit Note in such principal amount, dated July
         14, 1994, executed by the Debtor and payable to Bank; and

                  2. all obligations of Debtor pursuant to any and all renewals,
         modifications, or extensions, in whole or in part, of the Note; and

                  3. all obligations of the Debtor under and pursuant to any
         deed of trust, mortgage, security agreement, assignment of rents and
         leases, or other security document (collectively herein called
         "Security Documents") which now or hereafter secures the payment of the
         indebtedness evidenced by the Note; and

                  4. all obligations of Debtor pursuant to any and all renewals,
         modifications, or extensions, in whole or in part, of any of the
         Security Documents;

<PAGE>

together with all expenses, legal and/or otherwise (including court costs and
reasonable attorney's fees) incurred by the Bank in collecting or endeavoring to
collect the Indebtedness, or any part thereof, in protecting any collateral, and
in enforcing this Guaranty (all of which is hereinafter collectively referred to
as the "Indebtedness").

         THIS GUARANTY SHALL BE A CONTINUING, ABSOLUTE AND UNCONDITIONAL
GUARANTY, and shall remain in full force and effect until the Indebtedness (and
interest thereon and expenses in connection therewith), and all renewals,
modifications, or extensions thereof, in whole or in part, shall have been fully
paid and satisfied and shall remain in full force and effect until written
notice of its discontinuance, addressed to the President of the Bank, shall be
actually received by the Bank (the burden of proof of receipt by the Bank of
such notice being in all cases upon the Guarantor), and also until any and all
said indebtedness, or any extensions or renewals thereof, existing before
receipt of such notice, and expenses in connection therewith, shall be fully
paid. Regardless of when a renewal or extension of pre-termination debt occurs
(with or without adjustment of interest rate or other terms), the debt is deemed
to have been incurred prior to termination to the extent of the renewal or
extension, and to be fully covered by this Guaranty. The death, dissolution or
withdrawal of the Guarantor (or any of them, if more than one) shall not
terminate this Guaranty until notice of any such death, dissolution or
withdrawal, given as above provided, shall have actually been received by the
Bank, and until all of said indebtedness, or any extensions or renewals thereof,
existing before receipt of such notice shall be fully paid. And in the event of
any such death, dissolution or withdrawal and notice thereof to the Bank, this
Guaranty shall, notwithstanding, continue and remain in force against any
surviving Guarantor until discontinued as hereinabove provided.

         The Bank is hereby expressly authorized to make from time to time,
without notice to anyone: any renewals, modifications or extensions, whether
such renewals, modifications or extensions be in whole or in part and without
limit as to the number of such extensions or of the renewal periods thereof, and
without notice to or further assent from the undersigned, sales, pledges,
surrenders, compromises, settlements, releases, indulgences, alterations,
substitutions, exchanges, changes in, modifications, or other dispositions
including, without limitation, cancellations, of all or any part of the
collateral pledged to secure the Indebtedness or any part of said Indebtedness,
either express or implied, or of any contracts or instruments evidencing any
thereof, or of any security or collateral therefor, and/or to take any security
for or other guaranties upon any of said Indebtedness; and the liability of the
Guarantor (or any of them, if more than one) shall not be in any manner
affected, diminished or impaired thereby, or by any lack of diligence, failure,
neglect or omission on the part of the Bank to make any demand or protest, or
give any notice of dishonor or default, or to realize upon or protect any of
said Indebtedness, or any collateral or security therefor, or to exercise any
lien upon or right of appropriation or setoff of any moneys, accounts, credits,
or property of said Debtor, possessed by the Bank, towards the liquidation of
said Indebtedness, or by any application of payments or credits thereon. The
Bank shall have the exclusive right to determine how, when and what application
of payments and credits, if any, shall be made on said Indebtedness, or any part
thereof, and shall be under no obligation, at any time, to first resort to, make
demand on, file a claim against, or exhaust its remedies against the Debtor, or
any one or more of the Guarantors, or other persons or corporations, their
properties or estates, or to resort to or exhaust its remedies against, any
collateral, security, property, liens or other rights whatsoever. It is
expressly agreed that the Bank may at any time make demand for payment on, or
bring suit against the Guarantor

                                      -2-
<PAGE>

(or any of them, if more than one), or any other guarantors, may compound with
the Guarantor or any other guarantor for such sums or on such terms as Bank may
see fit and release the Guarantor (or any of them, if more than one) or any
other guarantor from all further liability to the Bank, without thereby
impairing the rights of the Bank in any respect to demand, sue for and collect
the balance of the Indebtedness from any guarantor not so released; and that any
claims against Debtor, against any other guarantor, or against any collateral,
accruing to the Guarantor (or any of them, if more than one) by reason of
payments made hereunder shall be in all respects junior and subordinate to any
obligation then or subsequently owed by the Debtor or by such other guarantor to
the Bank. In addition, the liability of the Guarantors (or each of them, if more
than one) shall not be affected by any lack of validity or enforceability of the
guaranteed debt. As security for the undertakings and obligations of the
Guarantor hereunder, the Guarantor (or each of them, if more than one) expressly
grants and gives to the Bank a right of immediate setoff, without demand or
notice, of the balance of every deposit account, now or at any time hereafter
existing, of the Guarantor (or each of them, if more than one) with the Bank,
and a general lien upon, and security interest in all money, negotiable
instruments, commercial paper, notes, bonds, stocks, credits and/or choses in
action, or any interest therein, and any other property, rights, and interests
of the Guarantor (or each of them, if more than one) or any evidence thereof,
which have or any time shall come into the possession, custody, or control of
the Bank, and, in the event of default hereunder, the Bank may sell or cause to
be sold at public or private sale in any manner which may be lawful, for cash or
credit and upon such terms as the Bank may see fit, and (except as may be
otherwise expressly provided by the Uniform Commercial Code, or other applicable
law) without demand or notice to the Guarantor (or each of them, if more than
one), all or any of such security, and the Bank (unless prohibited by the
Uniform Commercial Code from so doing) or any other person may purchase such
property, rights or interests so sold and thereafter hold the same free of any
claim or right of whatsoever kind, including any right or equity or redemption,
of the Guarantor (or each of them, if more than one), such demand, notice, right
or equity of redemption being hereby expressly waived and released.

         In the event of the death, incompetency, dissolution, liquidation,
insolvency (however evidenced) of the Debtor, or institution of bankruptcy or
receivership proceedings by the Debtor, or in the event that any involuntary
bankruptcy or receivership proceedings filed against the Debtor shall not be
dismissed within thirty (30) days following the institution of such proceedings,
then and in any such event all of the Indebtedness shall, for the purposes of
this Guaranty, and at the option of the Bank, immediately become due and payable
from the Guarantor; and, in such event, any and all sums or payments of any
nature which may be or become due and payable by the Debtor to the undersigned
are hereby assigned to the Bank, and shall be collectible by the Bank, without
necessity for other authority than this instrument, until the Indebtedness shall
be fully paid and discharged, but such collection by the Bank shall not in any
respect affect, impair or diminish any other rights of the Bank hereunder.

         The granting of credit from time to time by the Bank to the Debtor, in
excess of the amount to which right of recovery under this Guaranty is limited
and without notice to the Guarantor (or any of them, if more than one), is
hereby expressly authorized and shall in no way affect or impair this Guaranty;
and, in the event that the Indebtedness of the Debtor to the Bank shall so
exceed the amount to which this Guaranty is limited, any payment by the Debtor
or any collections or recovery by the Bank from any sources other than this
Guaranty may first be

                                      -3-
<PAGE>

applied by the Bank to any portion of the Indebtedness which exceeds the limits
of this Guaranty.

         The Guarantor (or each of them, if more than one) will not exercise any
rights that Guarantor (or any of them, if more than one) may acquire by way of
subrogation under this Guaranty, by any payment made hereunder or otherwise,
until all of the Indebtedness shall have been paid in full. If any amount shall
be paid to the Guarantor (or any of them, if more than one) on account of such
subrogation rights at any time when all the Indebtedness shall not have been
paid in full, such amount shall be held in trust for the benefit of the Bank and
shall forthwith be paid to the Bank to be credited and applied upon the
Indebtedness.

         NOTWITHSTANDING ANY PROVISION OF THE PRECEDING PARAGRAPH TO THE
CONTRARY, IF AT ANY TIME THE GUARANTOR (OR ANY OF THEM, IF MORE THAN ONE) IS OR
BECOMES AN "INSIDER" (AS DEFINED FROM TIME TO TIME IN SECTION 101 OF THE FEDERAL
BANKRUPTCY CODE) WITH RESPECT TO THE DEBTOR, THE GUARANTOR (OR EACH OF THEM, IF
MORE THAN ONE) WAIVES ANY AND ALL RIGHTS OF SUBROGATION AGAINST THE DEBTOR WITH
RESPECT TO THIS GUARANTY, WHETHER SUCH RIGHTS ARISE UNDER AN EXPRESS OR IMPLIED
CONTRACT OR BY OPERATION OF LAW, IT BEING THE INTENTION OF THE PARTIES THAT, IF
ANY GUARANTOR IS AN "INSIDER" WITH RESPECT TO THE DEBTOR, THE GUARANTOR SHALL
NOT BE DEEMED TO BE A "CREDITOR" (AS DEFINED IN SECTION 101 OF THE FEDERAL
BANKRUPTCY CODE) OF THE DEBTOR, BY REASON OF THE EXISTENCE OF THIS GUARANTY IN
THE EVENT THAT THE DEBTOR BECOMES A DEBTOR IN ANY PROCEEDING UNDER THE FEDERAL
BANKRUPTCY CODE.

         Notwithstanding any other provision of this Guaranty to the contrary,
if the obligations of the Guarantor hereunder would otherwise be held or
determined by a court of competent jurisdiction in any action or proceeding
involving any state corporate law or any state or Federal bankruptcy,
insolvency, reorganization, moratorium, fraudulent conveyance or other law
affecting the rights of creditors generally, to be void, invalid or
unenforceable to any extent on account of the amount of the Guarantor's (or each
of them, if more than one) liability under this Guaranty, then notwithstanding
any other provision of this Guaranty to the contrary, the amount of such
liability shall, without any further action by the Guarantor (or each of them,
if more than one) or any other person, be automatically limited and reduced to
the highest amount which is valid and enforceable as determined in such action
or proceeding.

         The Bank may without any notice whatsoever to anyone, sell, assign or
transfer all or any part of said Indebtedness; and in that event each and every
immediate and successive assignee, transferee or holder of all or any part of
said Indebtedness shall have the right to enforce this Guaranty, by suit or
otherwise, for the benefit of such assignee, transferee or holder, as fully as
though such assignee, transferee or holder were herein by name given such
rights, powers and benefits; but the Bank shall have an unimpaired right, prior
and superior to that of any said assignee, transferee or holder, to enforce this
Guaranty for the benefit of the Bank, as to so much of said Indebtedness that
has not been sold, assigned or transferred.

         No act of commission or omission of any kind, or at any time, on the
part of the Bank in respect of any matter whatsoever shall in any way affect or
impair this Guaranty. This Guaranty is in addition to and not in substitution
for or discharge of any other Guaranty held by the Bank. The Guarantor (or each
of them, if more than one) waives any rights of action Guarantor (or any

                                      -4-
<PAGE>

of them, if more than one) might have against the Bank because of the exercise
by the Bank in any manner howsoever of any rights granted to the Bank herein.

         This Guaranty contains the entire agreement between the parties and
every part thereof shall be binding upon the Guarantor (or each of them, if more
than one), Guarantor's successors and assigns, as fully as though everywhere
specifically mentioned, and shall inure to the benefit of the Bank, and its
successors and assigns, and shall be construed according to the laws of the
State of Tennessee, in which state it is accepted by the Bank.

         If any provision hereof is invalid or unenforceable, the remaining
provisions hereof shall not be affected by such invalidity or unenforceability.
Each term and provision contained herein shall, however, be valid and
enforceable to the fullest extent permitted by applicable law.

         The Guarantor (or each of them, if more than one) acknowledges that
this Guaranty Agreement is and shall be effective against such Guarantor upon
execution by such Guarantor (regardless of whether any other person named herein
as Guarantor shall sign), and delivery hereof to the Bank, or its agent; and
that it shall not be necessary for the Bank to execute any acceptance hereof or
otherwise to signify or express its acceptance hereof.

         ALL OF THE PARTIES HEREBY WAIVE TRIAL BY JURY IN ANY ACTION, PROCEEDING
OR COUNTERCLAIM BROUGHT BY ANY OF THE PARTIES AGAINST THE OTHER ON ANY MATTER
WHATSOEVER ARISING OUT OF OR IN ANY WAY CONNECTED WITH THIS AGREEMENT OR UNDER
ANY AMENDMENT, INSTRUMENT, DOCUMENT OR AGREEMENT DELIVERED (OR WHICH MAY BE
DELIVERED IN THE FUTURE) IN CONNECTION HEREWITH OR ARISING FROM ANY BANKING
RELATIONSHIP BETWEEN THE PARTIES TO THIS AGREEMENT.

         IN WITNESS WHEREOF, the Guarantor (or each of them, if more than one)
has caused this Guaranty Agreement to be executed by its duly authorized
officers on this the 16th day of October, 2001.

                SECOND AMENDED AND RESTATED REVOLVING CREDIT NOTE

$40,000,000.00                                                Memphis, Tennessee
                                                          As of October 16, 2001

         On July 31, 2002, the undersigned, SUSA PARTNERSHIP, L.P., a Tennessee
limited partnership (the "Maker"), promises to pay to the order of FIRST
TENNESSEE BANK NATIONAL ASSOCIATION, a national banking association having its
principal place of business in Memphis, Tennessee (the "Bank"), the lesser of
(i) the principal sum of FORTY MILLION DOLLARS ($40,000,000.00), or (ii) the
outstanding principal balance hereof, value received, together with interest
from date until paid, upon disbursed and unpaid principal balances, at the rate
hereinafter specified, said interest being payable on each Interest Payment Date
(as defined in the Loan Agreement), with the final installment of interest being
due and payable concurrently on the same date that the principal balance is due
hereunder.

         Subject to the limitations hereinafter set forth, the disbursed and
unpaid principal balances of the indebtedness hereby evidenced shall bear
interest prior to maturity at a variable rate per annum which shall, from day to
day, be equal to the lesser of (a) the maximum variable rate of interest
("Maximum Rate") which Bank may from time to time lawfully charge, or (b) the
variable rate chosen by the Maker pursuant to the terms of that certain Second
Amended and Restated Loan Agreement between the Maker and the Bank, of even date
herewith (the "Loan Agreement").

         In the event that the provisions of the Loan Agreement regarding the
interest rate should be construed by a court of competent jurisdiction not to
constitute a valid, enforceable designation of a rate of interest or method of
determining same, the indebtedness hereby evidenced shall bear interest at the
maximum effective variable contract rate which may be charged by the Bank under
applicable law from time to time in effect.

         All installments of interest, and the principal hereof, are payable at
the office of First Tennessee Bank National Association, 165 Madison Avenue,
Memphis, Tennessee 38103, or at such other place as the holder may designate in
writing, in lawful money of the United States of America, which shall be legal
tender in payment of all debts and dues, public and private, at the time of
payment.

         Any amounts not paid when due hereunder (whether by acceleration or
otherwise) shall bear interest after maturity at the Maximum Rate.

         If the Maker shall fail to make payment of any installment of interest,
as above provided, and such failure shall continue for ten (10) days past the
applicable due date or upon any default in the terms and provisions of the Loan
Agreement of even date herewith between the Maker and the Bank, or upon any
default in any other mortgage, trust deed, security agreement, or other
instrument of pledge or hypothecation which now or hereafter secures the payment
of the indebtedness evidenced hereby, or upon the death or dissolution of the
Maker or any endorser or guarantor or (if the Maker, or any endorser or
guarantor is a partnership) the death or dissolution of any general partner
thereof, or upon any default in full payment, promptly as and when due

<PAGE>

(whether by reason of demand, acceleration or otherwise) of any other
indebtednesses, liabilities or obligations of the Maker to the Bank, whether now
existing or hereafter created or arising, absolute or contingent, due or to
become due, then, in any of such events, the entire unpaid principal balance of
the indebtedness evidenced hereby together with all interest then accrued,
shall, at the absolute option of the Bank, at once become due and payable,
without demand or notice, the same being expressly waived.

         If this Note is placed in the hands of an attorney for collection, by
suit or otherwise, or to protect the security for its payment, or to enforce its
collection, or to represent the rights of the Bank in connection with any loan
documentation executed in connection herewith, or to defend successfully against
any claim, cause of action or suit brought by the Maker against the Bank, the
Maker shall pay on demand all costs of collection and litigation (including
court costs), together with a reasonable attorney's fee.

         The Maker and any endorsers or guarantors hereof waive protest, demand,
presentment, and notice of dishonor, and agree that this Note may be extended,
in whole or in part, without limit as to the number of such extensions or the
period or periods thereof, without notice to them and without affecting their
liability hereon.

         This Second Amended and Restated Revolving Credit Note evidences the
same indebtedness as that evidenced by the Amended and Restated Revolving Credit
Note (the "Amended Note") dated as of May 4, 1998, in the principal amount of
Forty Million Dollars ($40,000,000.00) issued by the Maker to the Bank. To the
extent of Fifteen Million Dollars ($15,000,000.00), the Amended Note evidenced
the same indebtedness as that evidenced by the Revolving Credit Note (the
"Original Note") dated as of July 14, 1994, in the principal amount of Fifteen
Million Dollars ($15,000,000.00) issued by the Maker to the Bank. This Second
Amended and Restated Revolving Credit Note is a restatement of the Amended Note.
The execution and delivery of this Second Amended and Restated Revolving Credit
Note does not constitute payment, cancellation, satisfaction, discharge, release
or novation of the Amended Note or Original Note or the indebtedness evidenced
by the Amended Note and Original Note, and such Amended Note and Original Note
shall continue to constitute evidence of such indebtedness.
