<PAGE>

as such other parties may reasonably request to consummate the transactions
contemplated hereby.

                  2.6      USE OF PROCEEDS. In no event shall any proceeds from
the sale of the TCW Sub Notes be used directly or indirectly by any Person for

"margin stock" or any "margin securities" (as such terms are defined
respectively in Regulations T, U and X promulgated by the Board of Governors of

for the purpose of purchasing or carrying any such margin stock or margin
securities. Inland represents and warrants to the Note Purchaser that Inland is

time to time outstanding at the coupon rate of eleven percent (11%) per annum
compounded quarterly on each Quarterly Accrual Date, from and after the Closing

arrears in cash on each Payment Date, subject to any restriction on such payment
in the Bank Subordination Agreement. If interest on the TCW Sub Notes is not
paid in full on any Payment Date for any reason in cash, such interest shall be
accrued until and shall be due and payable on the Maturity Date. Inland shall
have the option to accrue interest (in lieu of cash payment thereof) until the

payments on each Payment Date shall be mandatory, subject to any restriction on
such payment in the Bank Subordination Agreement.

                  2.9      COMPUTATION OF INTEREST. Interest shall be computed
on the TCW Sub Notes on the basis of a 360-day year consisting of twelve 30-day
months. Interest on the TCW Sub Notes shall be computed as the sum of the daily
interest for the period prior to each Payment Date, taking into account the
outstanding principal balance of the TCW Sub Notes and accrued unpaid interest
on each day of the period (where such balance on any given day shall reflect any
payment of principal credited on such date pursuant to SECTION 2.12 hereof).

                  2.10     PAYMENT OF PRINCIPAL. Inland shall make payments of
principal on the TCW Sub Notes each in an amount equal to one-third of the

Requisite Holders and without premium or penalty.

                  (b)      Each prepayment of principal under this SECTION 2.11
shall be accompanied by all interest then accrued and unpaid on the principal so
prepaid. Any principal prepaid pursuant to this SECTION 2.11 shall be (i) in
addition to, and not in lieu of, all payments otherwise required to be paid
under the Note Purchase Documents at the time of such prepayment and (ii)
applied first, to accrued but unpaid interest on the TCW Sub Notes, and second,
to amortization payments of principal due under SECTION 2.10 in the direct order
of maturity.

                  2.12     GENERAL PAYMENT PROVISION.

such other directions as the Holders may from time to time specify). Any payment
received by the Holders after such time shall be deemed to have been made on the
next following Business Day. Should any such payment become due and payable on a
day other than a Business Day, the maturity of such payment shall be the
succeeding Business Day. Each payment under a Note Purchase Document shall be
due and payable at the place provided therein and, if no specific place of
payment is provided, shall be due and payable at the place of payment of the TCW
Sub Notes. When the Holders collect or receive money on account of the
Obligations which is insufficient to pay all Obligations then due and payable,
the Holders shall apply such money pursuant to SUBSECTION 2.12(B) below.

                  (b)      Payments or prepayments of principal or interest on
the TCW Sub Notes shall be applied ratably to such TCW Sub Notes. Except for
optional prepayments pursuant to SECTION 2.11 (which shall be applied as
provided in SECTION 2.11), any amount received by any Holder, whether as an
interest payment or principal payment from or on behalf of Inland, shall be
applied as follows in descending order of priority:

                           (i)      to all costs and expenses (including

                  Purchase Documents;

                           (iii)    to interest which has accrued on any amounts

                  pursuant to SECTION 2.8;

                           (iv)     to principal that is currently due and

20 days of receipt of the proposed Development Plan and failure to disapprove in
writing within such 20 day period shall constitute approval.

                  5.2      BOARD OF DIRECTORS REPRESENTATION. From and after the
date hereof until the Obligations are repaid in full, the Requisite Holders
shall have the right to Designate, upon written notice to Inland, either (a) one
member to each Board of Directors and one observer entitled to receive all
notices and distributions to members of each Board of Directors and to attend
all meetings thereof (including committees thereof) (an "OBSERVER") or (b) one
or two Observers to each Board of Directors. Any such person Designated by the
Requisite Holders that is elected to any Board of Directors pursuant to this
SECTION 5.2 shall have a term that automatically expires at such time as the
Obligations have been repaid in full. Only one member of each Board of Directors
(whether serving on the board of directors of Inland or any Subsidiary) so
Designated by the Requisite Holders pursuant to this SECTION 5.2, as long as
such Designated member is an independent member (I.E., not an employee or
Affiliate of TCW or an employee or Affiliate of such Affiliate), shall be
entitled to receive compensation, and only one

                                       10
<PAGE>

Designated member of each Board of Directors and one Observer shall be entitled
to receive reimbursement of reasonable travel and other expenses as provided in
the Shareholders Agreement.

                  5.3      INCREASED BOARD OF DIRECTORS REPRESENTATION ARISING
FROM INTEREST NON-PAYMENT. If any cash payment of interest is not made on any
Quarterly Payment Date on or after the Interest Payment Commencement Date,
solely by reason of a restriction or prohibition on such payment in the Bank
Subordination Agreement which is not waived by the Banks (an "INTEREST
NON-PAYMENT"), in addition to their rights under SECTION 5.2 hereof, the
Requisite Holders shall have the right to Designate one or more individuals ("RH
DESIGNEE(S)") to become a member of the Board of Directors and, cause such RH
Designee(s) to become a member of each Board of Directors as provided herein.
Subject to SECTION 9.2(D), such right shall accrue at the rate of one director
on every Board of Directors for each two Calendar Quarter period in which
interest is not paid in full commencing on the first day of the Calendar Quarter
in which the Interest Non-Payment occurs, until all interest accrued from the
first day of the Calendar Quarter in which the first Interest Non-Payment
occurred is paid in full in cash. Subject to SECTION 9.2(D), so long as an
Interest Non-Payment has occurred and is continuing, such right to cause RH
Designees to become a member of every Board of Directors will accumulate and the
Requisite Holders shall keep and retain such right even if not exercised at the
end of any two Calendar Quarter period and shall have the right to have
additional RH Designees to become additional member(s) of every Board of
Directors pursuant to the foregoing sentence. By way of example, if an Interest
Non-Payment shall occur on September 30, 2005 and shall be continuing on
December 31, 2005, on and after January 1, 2006, so long as any Interest
Non-Payment is continuing, the Requisite Holders shall have the right to have
one RH Designee become a member of every Board of Directors and if any Interest
Non-Payment is continuing as of June 30, 2006, the Requisite Holders shall have
the right to have two RH Designees become members of every Board of Directors on
and after July 1, 2006. The right of the Requisite Holders to have one or more
RH Designees become a member of every Board of Directors pursuant to this
SECTION 5.3 shall be the sole remedy of the Holders with respect to any Interest
Non-Payment that has occurred and is continuing, unless such RH Designee(s) is
for any reason does not become a member of every Board of Directors as set forth
in SECTION 9.1(A)(II), and the Requisite Holders shall not have the right to
deliver the notice of Subordinated Payment Event of Default to the Agent
pursuant to SECTION 2(B)(3)(A) of the Bank Subordination Agreement so long as
any RH Designee(s) has become a member of every designated Board of Directors as
provided herein. Any RH Designee that becomes a member of any Board of Directors
pursuant to this SECTION 5.3 may be replaced by the holder(s) of a majority of
Inland's Common Stock upon the payment (the "CURE EVENT") in full in cash of
interest unpaid and accrued from the first day of the Calendar Quarter in which
the Interest Non-Payment occurred, or as an alternate to such replacement, shall
resign if requested by TCW and the vacancy shall be filled by the remaining
Board of Directors. Any RH Designee that becomes a member of any Board of
Directors pursuant to this SECTION 5.3 shall have a term that shall
automatically expire upon the occurrence of the Cure Event.

                  SECTION 7.        GUARANTY.

                  7.1      GUARANTY.

                  (a)      The Guarantor, for valuable consideration, the
receipt and sufficiency of which is hereby acknowledged, effective as of the
Closing, hereby unconditionally and irrevocably guarantees to each Holder of the
TCW Sub Notes at any time outstanding (a) the prompt, indefeasible payment in
full, in dollars, when due (whether at stated maturity, by acceleration, by
prepayment or otherwise) of the Obligations and (b) the prompt performance and
observance by Inland of all covenants, agreements and conditions on its part to
be performed and observed hereunder, in each case strictly in accordance with
the terms thereof (such payments and other obligations being herein collectively
called the "GUARANTEED OBLIGATIONS").

                  (b)      The Guarantor hereby further agrees that if Inland
shall default in the payment or performance of any of the Guaranteed
Obligations, the Guarantor will (x) promptly pay or perform the same, without
any demand or notice whatsoever, and that in the case of any extension of time
of payment or renewal of any of the Guaranteed Obligations, the same will be
promptly paid in full when due (whether at extended maturity, by acceleration,
by prepayment or otherwise) in accordance with the terms of such extension or
renewal and (y) pay to the Holder of any TCW Sub Note such amounts, to the
extent lawful, as shall be sufficient to pay the costs and expenses of
collection or of otherwise enforcing any of such Holder's rights under this
Agreement, including, without limitation, reasonable counsel fees. Anything in
any Note Purchase Document to the contrary notwithstanding, the maximum
liability of the Guarantor under this Agreement shall in no event exceed the
amount which can be guaranteed by the Guarantor under applicable Laws relating
to the insolvency of debtors (after giving effect to the right of contribution
established in the following paragraph). the Guarantor further agrees that the
Guaranteed Obligations may at any time and from time to time exceed the amount
of the liability of the Guarantor under this Agreement without impairing the
guarantee contained in this Section or affecting the rights and remedies of any
Holder of any TCW Sub Notes.

                                      13
<PAGE>

                  (c)      All obligations of the Guarantor under this Section
shall survive any transfer of any TCW Sub Note, and any obligations of the
Guarantor under this Section with respect to which the underlying obligation of
Inland is expressly stated to survive payment of any TCW Sub Note shall also
survive payment of such TCW Sub Note.

                  7.2      OBLIGATIONS UNCONDITIONAL.

                  (a)      Upon effectiveness, the obligations of the Guarantor
hereunder constitute a present and continuing guaranty of payment and not of
collectibility and are absolute and unconditional, irrespective of the value,
genuineness, validity, regularity or enforceability of the Obligations, or any
substitution, release or exchange of any other guarantee of or security for any
of the Guaranteed Obligations, and, to the fullest extent permitted by
applicable Law, irrespective of any other circumstance whatsoever which might
otherwise constitute a legal or equitable discharge or defense of a surety or
guarantor, it being the intent of this Section that the obligations of the
Guarantor hereunder shall, upon effectiveness, be absolute and unconditional,
under any and all circumstances. Without limiting the generality of the
foregoing, it is agreed that the occurrence of any one or more of the following
shall not alter or impair the liability of the Guarantor hereunder which shall
remain absolute and unconditional as described above:

                           (i)      any amendment or modification of any
                  provision of this Agreement or any of the TCW Sub Notes or any
                  assignment or transfer thereof, including without limitation
                  the renewal or extension of the time of payment of any of the
                  TCW Sub Notes or the granting of time in respect of such
                  payment thereof, or of any furnishing or acceptance of
                  security or any additional guarantee or any release of any
                  security or guarantee so furnished or accepted for any of the
                  TCW Sub Notes;

                           (ii)     any waiver, consent, extension, granting of
                  time, forbearance, indulgence or other action or inaction
                  under or in respect of this Agreement or the TCW Sub Notes, or
                  any exercise or non-exercise of any right, remedy or power in
                  respect hereof or thereof;

                           (iii)    any bankruptcy, receivership, insolvency,
                  reorganization, arrangement, readjustment, composition,
                  liquidation or similar proceedings with respect to Inland or
                  any other Person or the Properties or creditors of any of
                  them;

                           (iv)     the occurrence of any Default or Event of
                  Default under, or any invalidity or any unenforceability of,
                  or any misrepresentation, irregularity or other defect in,
                  this Agreement, the TCW Sub Notes or any other Note Purchase
                  Document;

                           (v)      any transfer of any assets to or from
                  Inland, including without limitation any transfer or purported
                  transfer to Inland from any Person, any invalidity, illegality
                  of, or inability to enforce, any such transfer or purported
                  transfer, any consolidation or merger of Inland with or into
                  any Person, any change in the ownership of any shares of
                  capital stock or similar equity interests

                                      14
<PAGE>

                  of Inland, or any change whatsoever in the objects, capital
                  structure, constitution or business of Inland;

                           (vi)     any default, failure or delay, willful or
                  otherwise, on the part of Inland or any other Person to
                  perform or comply with, or the impossibility or illegality of
                  performance by Inland or any other Person of, any term of this
                  Agreement, the TCW Sub Notes or any other Note Purchase
                  Document;

                           (vii)    any suit or other action brought by, or any
                  judgment in favor of, any beneficiaries or creditors of,
                  Inland or any other Person for any reason whatsoever,
                  including without limitation any suit or action in any way
                  attacking or involving any issue, matter or thing in respect
                  of this Agreement, the TCW Sub Notes or any other Note
                  Purchase Document;

                           (viii)   any lack or limitation of status or of
                  power, incapacity or disability of Inland or any trustee or
                  agent thereof; or

                           (ix)     any other thing, event, happening, matter,
                  circumstance or condition whatsoever, not in any way limited
                  to the foregoing.

                  (b)      The Guarantor hereby unconditionally waives
diligence, presentment, demand of payment, protest and all notices whatsoever
and any requirement that any Holder of a TCW Sub Note exhaust any right, power
or remedy against Inland under this Agreement or the TCW Sub Notes or any other
Note Purchase Document, or against any other Person under any other guarantee
of, or security for, any of the Guaranteed Obligations.

                  (c)      In the event that the Guarantor shall at any time pay
any amount on account of the Guaranteed Obligations or take any other action in
performance of its obligations hereunder, the Guarantor shall not exercise any
subrogation or other rights hereunder or the TCW Sub Notes and the Guarantor
hereby waives all rights it may have to exercise any such subrogation or other
rights, and all other remedies that it may have against Inland, in respect of
any payment made hereunder unless and until the Guaranteed Obligations shall
have been indefeasibly paid in full. If any amount shall be paid to the
Guarantor on account of any such subrogation rights or other remedy,
notwithstanding the waiver thereof, such amount shall be received in trust for
the benefit of the Holders of the TCW Sub Notes and shall forthwith be paid to
such Holders to be credited and applied upon the Guaranteed Obligations, whether
matured or unmatured, in accordance with the terms hereof. The Guarantor agrees
that its obligations under this Section shall be automatically reinstated if and
to the extent that for any reason any payment (including payment in full) by or
on behalf of Inland is rescinded or must be otherwise restored by any Holder of
a TCW Sub Note, whether as a result of any proceedings in bankruptcy or
reorganization or otherwise, all as though such amount had not been paid.

                  (d)      The guarantee in this Section is a continuing
guarantee and shall apply to the Guaranteed Obligations whenever arising. Each
default in the payment or performance of any of the Guaranteed Obligations shall
give rise to a separate claim and cause of action hereunder, and separate claims
or suits may be made and brought, as the case may be, hereunder as each such
default occurs.

                                      15
<PAGE>

                  7.3      GUARANTEE ENDORSED ON THE TCW SUB NOTES. Each TCW Sub
Note shall have endorsed thereon a Guarantee executed by the Guarantor in the
form of EXHIBIT B attached hereto.

                  SECTION 8.        TRANSFERABILITY OF TCW SUB NOTES.

                  8.1      RESTRICTIVE LEGEND. Each note evidencing the TCW Sub
Notes issued by Inland shall be stamped or otherwise imprinted with a legend in
substantially the following form:

                  "THE SECURITIES EVIDENCED BY THIS TCW SUB NOTE HAVE NOT BEEN
                  REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR
                  ANY STATE SECURITIES LAWS. NEITHER THIS SECURITY NOR ANY
                  INTEREST OR PARTICIPATION HEREIN MAY BE OFFERED, SOLD,
                  ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE
                  DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION OR UNLESS SUCH
                  TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO, REGISTRATION."

PROVIDED, that such restrictive legend shall not be required after the date on
which the securities evidenced by a TCW Sub Note bearing such restrictive legend
no longer constitute Restricted Securities, and upon the request of the holder
of such certificate and subject to the last sentence of SECTION 8.2, Inland,
without expense to the Holder, shall issue a new TCW Sub Note not bearing the
restrictive legend otherwise required to be borne thereby.

                  8.2      RULE 144 AND 144A. At any time when Inland is subject
neither to Section 13 nor Section 15(d) of the Exchange Act, Inland will, with
reasonable promptness upon the request of any Holder, in order to permit such
Holders to transfer if they so desire, pursuant to Rule 144 or 144A promulgated
by the Commission (or any successor to such rule), comply with all rules and
regulations of the Commission applicable in connection with use of Rule 144 and
144A (or any successor rules thereto), including the provision of information
concerning Inland to such Holders and the timely filing of all reports with the
Commission in order to enable such Holders, if they so elect, to utilize Rule
144 or 144A, and Inland will cause any restrictive legends to be removed and any
transfer restrictions to be rescinded with respect to any sale of TCW Sub Notes
which is exempt from registration under the Securities Act pursuant to Rule 144
or 144A. If the Note Purchaser shall request that the restrictive legend on the
TCW Sub Note be removed, the Note Purchaser, if requested by Inland, will have
the obligation in connection with such request, at the Note Purchaser's expense,
of delivering an opinion of counsel in form and substance reasonably
satisfactory to Inland, in connection with such request, to the effect that the
removal of such restrictive legend would not be in violation of the Securities
Act or any applicable state securities laws.

                  SECTION 9.        EVENTS OF DEFAULT AND REMEDIES.

                  9.1      EVENTS OF DEFAULT.

                  (a)      If (i) any of the events listed on ANNEX D attached
hereto (other than with respect to the failure to comply with SECTION 5.3
hereof), shall occur and be continuing it shall

                                      16
<PAGE>

constitute an "Event of Default" under this Agreement, or (ii) any RH Designee
Designated by the Requisite Holders pursuant to SECTION 5.3 to any Board of
Directors shall not become a member of such Board of Directors for any reason
whatsoever on or before the fifteenth (15th) day (or thirtieth (30th) day if
Rule 14f-1 promulgated under the Exchange Act is applicable) after the date the
Requisite Holders give notice to Inland of the Designation of such RH
Designee(s) to become a member of each Board of Directors, it shall constitute
an "Event of Default" under this Agreement.

                  (b)      Subject to the restrictions in the Bank Subordination
Agreement, upon the occurrence and continuation of an Event of Default described
in clauses (e)(i) - (iii) of SECTION D-1 of ANNEX D or the acceleration of the
Senior Bank Debt, the Senior Sub Debt or the Junior Sub Debt, all of the
Obligations shall thereupon be immediately due and payable, without demand,
presentment, notice of demand or of dishonor and nonpayment, protest, notice of
protest, notice of intention to accelerate, declaration or notice of
acceleration, or any other notice or declaration of any kind, all of which are
hereby expressly waived by Inland. Subject to the restrictions in the Bank
Subordination Agreement, during the continuance of any other Event of Default
(except as provided below in SECTION 9.2), the Requisite Holders at any time and
from time to time may without notice to Inland declare any or all of the
Obligations immediately due and payable, and all such obligations shall
thereupon be immediately due and payable, without demand, presentment, notice of
demand or of dishonor and nonpayment, protest, notice of protest, notice of
intention to accelerate, declaration or notice of acceleration, or any other
notice or declaration of any kind, all of which are hereby expressly waived by
Inland.

                  9.2      REMEDIES.

                  (a)      Subject to the restrictions in the Bank Subordination
Agreement, if any Event of Default shall occur, the Requisite Holders may
protect and enforce their rights under the Note Purchase Documents by any
appropriate proceedings, including proceedings for specific performance of any
covenant or agreement contained in any Note Purchase Document, and the Requisite
Holders may enforce the payment of any Obligations due or enforce any other
legal or equitable right. Notwithstanding SECTION 9.1 above or this SECTION 9.2,
if any Event of Default shall occur as a result of a breach of the working
capital covenant set forth in SECTION C-1.9 of ANNEX C hereto while the Senior
Bank Debt is still outstanding, the Holders shall not be entitled to take any
action including without limitation acceleration of the TCW Sub Notes or the
exercise of other remedies under SECTION 9.1 or this SECTION 9.2, unless there
has been an acceleration of the Senior Bank Debt as a result thereof.

                  (b)      Upon the occurrence and continuation of any Event of
Default (other than pursuant to SECTION 9.1(A)(II) of this Agreement), the
Requisite Holders shall have the unqualified right to Designate RH Designees for
election and cause such RH Designees to become members of each Board of
Directors as provided herein. Such right shall accrue immediately upon the
occurrence of such Event of Default and thereafter at the rate of one director
for each ninety day period after the date on which such Event of Default occurs
until all Events of Default are cured or waived. So long as any Event of Default
(other than pursuant to SECTION 9.1(A)(II) of this Agreement) shall be
continuing, the Requisite Holders shall keep and retain such right even if not
exercised and shall have the right to have additional RH Designees become
additional member(s) of every Board of Directors which shall become exercisable
every

                                      17
<PAGE>

ninety (90) days thereafter. The foregoing right and remedy of Holders shall not
be an exclusive remedy with respect to any Event of Default (other than pursuant
to SECTION 9.1(A)(II) of this Agreement) and shall be cumulative with all other
remedies. Any RH Designee that becomes a member of any Board of Directors
pursuant to this SECTION 9.2(B) shall have a term that shall automatically
expire upon the date such Event of Default is cured or waived.

                  (c)      Any RH Designee elected to any Board of Directors
pursuant to SECTION 9.2(B) may be replaced by the holder(s) of a majority of
Inland's Common Stock upon the cure of all outstanding Events of Default (other
than pursuant to SECTION 9.1(A)(II) of this Agreement), or as an alternate to
such replacement, shall resign if requested by TCW and the vacancy shall be
filled by the remaining Board of Directors.

                  (d)      Notwithstanding any provision of SECTION 5, SECTION
9, or any Transaction Document which might be construed to the contrary, as long
as each Board of Directors has no more than six members, the Requisite Holders
shall not be entitled to Designate or elect more than four of the six members at
any time that Hampton shall own more than 50% of the outstanding Common Stock of
Inland.

                  SECTION 10.       INDEMNITY.

                  The Companies jointly and severally agree to indemnify each
Indemnified Party, upon demand, from and against any and all liabilities,
obligations, claims, losses, damages, penalties, fines, actions, judgments,
suits, settlements, costs, expenses or disbursements (including reasonable fees
of attorneys, accountants, experts and advisors) of any kind or nature
whatsoever (in this section collectively called "LIABILITIES AND COSTS") which
to any extent (in whole or in part) may be imposed on, incurred by, or asserted
against such Indemnified Party arising out of, resulting from or in any other
way associated with (i) the Note Purchase Documents or any transaction
contemplated thereby, (ii) any matter, event or occurrence with respect to the
Note Purchaser and its Affiliates as shareholders and the Holders as noteholders
of the TCW Sub Notes or (iii) this Agreement, the Exchange or any of the
transactions and events (including the enforcement or defense thereof) at any
time associated therewith or contemplated therein (including any violation or
noncompliance with any Environmental Laws by any Related Person or any
liabilities or duties of any Related Person or of any Indemnified Party with
respect to Hazardous Materials found in or released into the environment).

THE FOREGOING INDEMNIFICATION SHALL APPLY WHETHER OR NOT SUCH LIABILITIES AND
COSTS ARE IN ANY WAY OR TO ANY WAY OR TO ANY EXTENT OWED, IN WHOLE OR IN PART,
UNDER ANY CLAIM OR THEORY OF STRICT LIABILITY OR ARE IN ANY EXTENT CAUSED, IN
WHOLE OR IN PART, BY ANY NEGLIGENT ACT OR OMISSION OF ANY KIND BY ANY
INDEMNIFIED PARTY,

provided only that no Indemnified Party shall be entitled under this section to
receive indemnification for that portion, if any, of any liabilities and costs
which is proximately caused by its own individual gross negligence or willful
misconduct, as determined in a final judgment. As used in this section, the term
"INDEMNIFIED PARTY" refers to each of TCW Asset Management Company, a California
corporation, Trust Company of the West, a California trust company and

                                      18

the Note Purchaser, (and each of their respective Affiliates) and each director,
officer, agent, trustee, manager, member, partner, shareholder, principal,
attorney, employee, representative and Affiliate of any such Person acting in
such capacity.

                  SECTION 11.       MISCELLANEOUS.

                  11.1     WAIVERS AND AMENDMENTS; ACKNOWLEDGMENT.

                  (a)      WAIVERS AND AMENDMENTS. No failure or delay (whether
by course of conduct or otherwise) by the Holders in exercising any right, power
or remedy which either may have under any of the Note Purchase Documents shall
operate as a waiver thereof or of any other right, power or remedy, nor shall
any single or partial exercise by the Holders of any such right, power or remedy
preclude any other or further exercise thereof or of any other right, power or
remedy. No waiver of any provision of any Note Purchase Document and no consent
to any departure therefrom shall ever be effective unless it is in writing and
signed by the Requisite Holders, or, if so specified, by the Majority Holder, if
any, and may be given or withheld in its sole and absolute discretion and then
such waiver or consent shall be effective only in the specific instances and for
the purposes for which given and to the extent specified in such writing. This
Agreement and the other Note Purchase Documents set forth the entire
understanding and agreement of the parties hereto and thereto with respect to
the transactions contemplated herein and therein and supersede all prior
discussions and understandings with respect to the subject matter hereof and
thereof, and no modification or amendment of or supplement to this Agreement or
the other Note Purchase Documents shall be valid or effective unless the same is
in writing and signed by the party against whom it is sought to be enforced.
THIS WRITTEN AGREEMENT AND THE OTHER NOTE PURCHASE DOCUMENTS REPRESENT THE FINAL
AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR,
CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. This Agreement
may be amended, but only with the written consent of each of the Companies and
the Requisite Holders. The remedies provided for herein are cumulative and are
not exclusive of any remedies that may be available to the Holders at Law or in
equity or otherwise.

                  (b)      ACKNOWLEDGMENTS AND ADMISSIONS. Inland hereby
represents, warrants, acknowledges and admits that:

                           (i)      it has been advised by counsel in the
                  negotiation, execution and delivery of the Note Purchase
                  Documents to which it is a party;

                           (ii)     it has made an independent decision to enter
                  into this Agreement and the other Note Purchase Documents to
                  which it is a party, without reliance on any representation,
                  warranty, covenant or undertaking by the Note Purchaser,
                  whether written, oral or implicit, other than as expressly set
                  out in this Agreement or in another Note Purchase Document
                  delivered on or after the date hereof,

                           (iii)    there are no representations, warranties,
                  covenants, undertakings or agreements by the Note Purchaser as
                  to the Note Purchase Documents except as

                                       19
<PAGE>

                  expressly set out in this Agreement or in another Note
                  Purchase Document delivered on or after the date hereof,

                           (iv)     The Note Purchaser, in its capacity as Note
                  Purchaser or a Holder, does not owe any fiduciary duty to
                  Inland with respect to any Note Purchase Document or the
                  transactions contemplated thereby;

                           (v)      the relationship pursuant to the Note
                  Purchase Documents between Inland, on the one hand, and the
                  Note Purchaser, on the other hand, is and shall be solely that
                  of debtor and creditor, respectively;

                           (vi)     no partnership or joint venture exists with
                  respect to the Note Purchase Documents between Inland and the
                  Note Purchaser;

                          (vii)     should an Event of Default or Default occur
                  or exist, the Note Purchaser will determine in its sole
                  discretion and for its own reasons what remedies and actions
                  it will or will not exercise or take at that time;

                           (viii)   without limiting any of the foregoing,
                  Inland is not relying upon any representation or covenant by
                  the Note Purchaser, or any representative thereof, and no such
                  representation or covenant has been made, that the Note
                  Purchaser will, at the time of an Event of Default or Default,
                  or at any other time, waive, negotiate, discuss, or take or
                  refrain from taking any action permitted under the Note
                  Purchase Documents with respect to any such Event of Default
                  or Default or any other provision of the Note Purchase
                  Documents; and

                           (ix)     the Note Purchaser has relied upon the
                  truthfulness of the acknowledgments in this Section in
                  deciding to execute and deliver this Agreement and to purchase
                  the TCW Sub Notes.

                  11.2     SURVIVAL OF AGREEMENTS; CUMULATIVE NATURE. All of the
Companies' various representations, warranties, covenants and agreements in this
Agreement and the Note Purchase Documents shall survive the execution and
delivery of this Agreement and the other Note Purchase Documents and the
performance hereof and thereof, including the purchase of the TCW Sub Notes and
the delivery of the TCW Sub Notes and the other Note Purchase Documents, and
shall further survive until all of the Obligations are paid in full to the
Holders and all of the Holders' obligations to Inland hereunder are terminated
or otherwise satisfied. Except as expressly provided herein, the
representations, warranties, and covenants made by Inland in the Note Purchase
Documents, and the rights, powers and privileges granted to the Holders in the
Note Purchase Documents, are cumulative, and, except for expressly specified
waivers and consents, no Note Purchase Document shall be construed in the
context of another to diminish, nullify, or otherwise reduce the benefit to the
Holders of any such representation, warranty, covenant, right, power or
privilege. In particular and without limitation, no exception set out in this
Agreement to any representation, warranty or covenant herein contained shall
apply to any similar representation, warranty or covenant contained in any other
Note Purchase Document, and each such similar representation, warranty or
covenant shall be subject only to

                                       20

those exceptions which are expressly made applicable to it by the terms of the
various Note Purchase Documents.

other communications required or permitted under any Note Purchase Document

                  11.4     GOVERNING LAW; SUBMISSION TO PROCESS. EXCEPT TO THE
EXTENT THAT THE LAW OF ANOTHER JURISDICTION IS EXPRESSLY ELECTED IN A NOTE
PURCHASE DOCUMENT, THE NOTE PURCHASE DOCUMENTS, INCLUDING THIS AGREEMENT, SHALL
BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE
OF NEW YORK, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW; PROVIDED, THAT
THE PROVISIONS OF SECTIONS 5.2, 5.3 AND 9.2 SHALL BE GOVERNED BY THE LAW OF THE
STATE OF WASHINGTON. INLAND HEREBY IRREVOCABLY SUBMITS ITSELF AND EACH OTHER
RELATED PERSON TO THE NON-EXCLUSIVE JURISDICTION OF THE STATE AND FEDERAL COURTS
SITTING IN THE STATE OF NEW YORK AND THE COUNTY OF NEW YORK AND AGREES AND
CONSENTS THAT SERVICE OF PROCESS MAY BE MADE UPON IT OR ANY OF ITS SUBSIDIARIES
IN ANY LEGAL PROCEEDING RELATING TO THE NOTE PURCHASE DOCUMENTS OR THE
OBLIGATIONS BY ANY MEANS ALLOWED UNDER NEW YORK OR FEDERAL LAW. INLAND
IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY
OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF THE VENUE OF ANY
SUCH PROCEEDING BROUGHT IN SUCH A COURT AND ANY CLAIM THAT ANY SUCH PROCEEDING
BROUGHT IN SUCH A COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM.

                  11.5     LIMITATION ON INTEREST.

                  (a)      The Holders, Inland and any other parties to the Note
Purchase Documents intend to contract in strict compliance with applicable usury
law from time to time in effect. In furtherance thereof such Persons stipulate
and agree that none of the terms and provisions contained in the Note Purchase
Documents shall ever be construed to create a contract to pay, for the use,
forbearance or detention of money, interest in excess of the maximum amount of
interest permitted to be charged by applicable law from time to time in effect.
Neither Inland nor any present or future guarantors, endorsers, or other Persons
hereafter becoming liable for payment of any Obligation shall ever be liable for
unearned interest thereon or shall ever be required to pay interest thereon in
excess of the maximum amount that may be lawfully charged under applicable law
from time to time in effect, and the provisions of this Section shall control
over all other provisions of the Note Purchase Documents which may be in
conflict or apparent conflict herewith.

                  (b)      The Holders expressly disavow any intention to
contract for, charge or collect unearned interest or finance charges in the
event the maturity of any Obligation is accelerated. If (i) the maturity of any
Obligation is accelerated for any reason, (ii) any Obligation is prepaid and as
a result any amounts held to constitute interest are determined to be in excess
of the legal maximum, or (iii) the Holders or any other holder of any or all of
the Obligations shall otherwise collect moneys which are determined to
constitute interest which would otherwise increase the interest on any or all of
the obligations to an amount in excess of that permitted to be charged by
applicable Law then in effect, then all such sums determined to constitute
interest in excess of such legal limit shall, without penalty, be promptly
applied to reduce the then-outstanding principal of the related Obligations or,
at the Holders' option, promptly returned to Inland or the other payor thereof
upon such determination.

                  (c)      In determining whether or not the interest paid or
payable under any specific circumstances exceeds the maximum amount permitted
under applicable Law, the Holders and the Related Persons (and any other payors
thereof) shall, to the greatest extent permitted under applicable law, (i)
characterize any non-principal payment as an expense, fee or premium rather than
as interest, (ii) exclude voluntary prepayments and the effects thereof, and
(iii) amortize, prorate, allocate, and spread the total amount of interest
throughout the entire contemplated term of the instruments evidencing the
Obligations in accordance with the amounts outstanding from time to time
thereunder and the Highest Lawful Rate from time to time in effect under
applicable Law in order to lawfully charge the maximum amount of interest
permitted under applicable Law.

                  11.6     TERMINATION; LIMITED SURVIVAL. Inland may, in its
sole and absolute discretion at any time that no Obligation is owing under the
Note Purchase Documents, elect in a notice delivered to the Holders to terminate
this Agreement. Upon receipt by the Holders of such a notice, if no such
Obligation is then owing, then this Agreement and all other Note Purchase
Documents shall thereupon be terminated and the parties thereto released from
all prospective obligations thereunder. Notwithstanding the foregoing or
anything herein to the contrary, any waivers or admissions made by Inland in any
Note Purchase Documents and any obligations which any Person may have to
indemnify or compensate the Holders shall survive any termination of this
Agreement or any other Note Purchase Document. At Inland's request

                                       22
<PAGE>

and expense, the Holders shall prepare and execute all necessary instruments to
reflect and effect such termination of the Note Purchase Documents. All
representations and warranties and covenants made herein by the Companies or in
any certificate or other instrument delivered by them or on their behalf under
this Agreement shall be considered to have been relied upon by TCW and shall
survive the issuance of the TCW Sub Notes regardless of any investigation made
by or on behalf of TCW.

                  11.7     REGISTRATION, TRANSFER, EXCHANGE AND SUBSTITUTION OF
TCW SUB NOTES. Inland shall keep at its principal executive office a register
for the registration and registration of transfers of TCW Sub Notes (the
"Register"). The name and address of each Holder, each transfer thereof and the
name and address of each transferee of one or more TCW Sub Notes shall be
registered in such Register. Prior to due presentment for registration of
transfer, the Person in whose name any TCW Sub Notes shall be registered shall
be deemed and treated as the owner and Holder thereof for all purposes hereof,
and Inland shall not be affected by any notice or knowledge to the contrary.
Inland shall give to any Holder, promptly upon request therefor, a complete and
correct copy of the names and addresses of all registered Holders of TCW Sub
Notes.

                  (a)      TRANSFER AND EXCHANGE OF TCW SUB NOTES. Upon
surrender of any TCW Sub Note at the principal executive office of Inland for
registration of transfer or exchange (and in the case of a surrender for
registration of transfer, duly endorsed or accompanied by a written instrument
of transfer duly executed by the registered Holder of such TCW Sub Note or its
attorney duly authorized in writing and accompanied by the address for notices
of each transferee of such TCW Sub Note or part thereof), Inland shall execute
and deliver, at Inland's expense, one or more new TCW Sub Note (as requested by
the Holder thereof) of the same series in exchange therefor, in an aggregate
principal amount equal to the unpaid principal amount of the surrendered TCW Sub
Note; provided, however, that no transfer of TCW Sub Notes may be made (i) to a
transferee who is not an accredited institutional investor or a qualified
institutional buyer and (ii) unless such transfer is made pursuant to an
exemption from registration under the securities laws of the United States
including without limitation any resale of any TCW Sub Notes under Rule 144A of
the Securities Act. Any purported transfer of a TCW Sub Notes or an interest
therein which is prohibited hereby shall be null and void ab initio and of no
force or effect whatever. Each such new TCW Sub Note shall be payable to such
Person as such holder may request and shall be substantially in the form of
Exhibit A. Each such new TCW Sub Note shall be dated and bear interest from the
date to which interest shall have been paid on the surrendered TCW Sub Note or
dated the date of the surrendered TCW Sub Note if no interest shall have been
paid thereon. TCW Sub Notes shall not be transferred in denominations of less
than $1,000,000 provided that if necessary to enable the registration of
transfer by a Holder of its entire holding of TCW Sub Notes, one TCW Sub Note
may be in a denomination of less than $1,000,000. If the Note Purchaser shall
request that the restrictive legend on the TCW Sub Note be removed, the Note
Purchaser, if requested by Inland, will have the obligation in connection with
such request, as applicable, at the Note Purchaser's expense, of delivering an
opinion of counsel in form and substance reasonably satisfactory to Inland, in
connection with such request to the effect that the removal of such restrictive
legend would not be in violation of the Securities Act or any applicable state
securities laws.

                                       23
<PAGE>

                  (b)      REPLACEMENT OF TCW SUB NOTES. Upon receipt by Inland
of evidence reasonably satisfactory to it of the ownership of and the loss,
theft, destruction or mutilation of any TCW Sub Notes, and (i) in the case of
loss, theft or destruction, of indemnity reasonably satisfactory to it (provided
that if the Holder of such TCW Sub Note is, or is a nominee for, the Note
Purchaser or another Holder of a TCW Sub Note with a minimum net worth of at
least $5,000,000, such Person's own unsecured agreement of indemnity shall be
deemed to be satisfactory), or in the case of mutilation, upon surrender and
cancellation thereof, Inland at its own expense shall execute and deliver, in
lieu thereof, a new TCW Sub Note of the same series, dated and bearing interest
from the date to which interest shall have been paid on such lost, stolen,
destroyed or mutilated TCW Sub Note or dated the date of such lost, stolen,
destroyed or mutilated TCW Sub Note if no interest shall have been paid thereon.

                  11.8     WAIVER OF JURY TRIAL, PUNITIVE DAMAGES, ETC. EACH OF
INLAND AND THE HOLDERS HEREBY:

                  (a)      KNOWINGLY, VOLUNTARILY, INTENTIONALLY, AND
IRREVOCABLY WAIVES, TO THE MAXIMUM EXTENT NOT PROHIBITED BY LAW, ANY RIGHT IT
MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED HEREON, OR
DIRECTLY OR INDIRECTLY AT ANY TIME ARISING OUT OF, UNDER OR IN CONNECTION WITH
THE NOTE PURCHASE DOCUMENTS OR THE PURCHASE AND SALE OF ANY TCW SUB NOTES
CONTEMPLATED THEREBY OR ASSOCIATED THEREWITH, BEFORE OR AFTER MATURITY;

                  (b)      IRREVOCABLY WAIVES, TO THE MAXIMUM EXTENT NOT
PROHIBITED BY LAW, ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY SUCH
LITIGATION ANY SPECIAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES, OR DAMAGES
OTHER THAN, OR IN ADDITION TO, ACTUAL DAMAGES;

                  (c)      CERTIFIES THAT NO PARTY HERETO NOR ANY REPRESENTATIVE
OR AGENT OR COUNSEL FOR ANY PARTY HERETO HAS REPRESENTED, EXPRESSLY OR
OTHERWISE, OR IMPLIED THAT SUCH PARTY WOULD NOT, IN THE EVENT OF LITIGATION,
SEEK TO ENFORCE THE FOREGOING WAIVERS; AND

                  (d)      ACKNOWLEDGES THAT IT HAS BEEN INDUCED TO ENTER INTO
THIS AGREEMENT, THE OTHER NOTE PURCHASE DOCUMENTS AND THE TRANSACTIONS
CONTEMPLATED HEREBY AND THEREBY BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND
CERTIFICATIONS CONTAINED IN THIS SECTION.

                  11.9     EXHIBITS AND SCHEDULES; ADDITIONAL DEFINITIONS. All
Exhibits and Schedules to this Agreement are a part hereof for all purposes.

                  11.10    CONFIDENTIALITY OF HOLDERS.

                  (a)      Notwithstanding the termination of this Agreement and
except as otherwise provided herein or in subsection (a) or (b) below, Inland
shall maintain the confidentiality of the identities of (i) any Holder or any
holder of any Obligation other than the TCW Sub Notes; and (ii) any owner of a
beneficial interest in the TCW Sub Notes (collectively, "CONFIDENTIAL
INFORMATION") and shall not, without the Requisite Holders' prior written
consent, disclose any such information to another Person or use such information
for purposes other than those contemplated herein.

                  (b)      Inland may disclose Confidential Information to its
directors, officers, members, employees, and agents (including attorneys,
accountants, and consultants) to whom such disclosure is reasonably necessary
for the execution or effectuation hereof, provided Inland notifies all such
Persons that the Confidential Information disclosed to them is subject to this
section and requires them not to disclose or use such information in breach of
this Section. Inland may also disclose Confidential Information in filings with
the Commission to the extent required to be disclosed therein.

                  (c)      If Inland is requested or required by legal process
(including law or regulation, oral questions, interrogatories, request for
information or documents, subpoena, and civil investigative demand) to disclose
any Confidential Information, Inland shall promptly notify the Holders of such
request prior to complying with such process so that the Holders may seek an
appropriate protective order or waive the respondent's compliance with this
section. If, after such notice and after providing the Holders a reasonable
opportunity to obtain a protective order or to grant such waiver (so long as the
granting of such time does not put Inland in breach of its obligations to
disclose), Inland is nonetheless legally compelled to disclose such information,
Inland may do so without liability under this Section.

                  (d)      Any Confidential Information which becomes publicly
available through no breach by Inland of its obligations hereunder or a breach
by a third party of a confidential obligation to the Holders shall no longer be
deemed to be Confidential Information.

                  11.11    REPRODUCTION OF DOCUMENTS This Agreement and all
documents relating hereto may be reproduced by you and by any photographic,
photostatic, microfilm, microcard, miniature photographic or other similar
process and you may destroy any original documents so produced. Each of the
parties hereto agrees and stipulates that, to the extent permitted by applicable
law, any such reproduction shall be admissible in evidence as the original
itself in any judicial or administrative proceeding (whether or not the original
is in existence and whether or not such reproduction was made by you in the
regular course of business) and any enlargement, facsimile or further
reproduction of such reproduction shall likewise be admissible in evidence.

                  11.12    SUCCESSORS AND ASSIGNS. Except as otherwise expressly
provided herein, this Agreement shall inure to the benefit of and be binding
upon the successors and assigns of each of the parties whether so expressed or
not.

                  11.13    COUNTERPARTS. Two or more duplicate originals of this
Agreement may be signed by the parties, each of which shall be an original but
all of which together shall constitute one and the same instrument.

                  11.14    SEVERABILITY. In the event that any one or more of
the provisions contained herein, or the application thereof in any circumstance,
is held invalid, illegal or unenforceable, the validity, legality and
enforceability of any such provision in every other respect and of the remaining
provisions contained herein shall not be affected or impaired thereby.

                  11.15    EXPENSES. The Companies will pay all reasonable costs
and expenses incurred by TCW and any other Holders (a) relating to the
negotiation, preparation, execution and delivery of this Agreement and the other
Note Purchase Documents and the issuance of the TCW Sub Notes (including,
without limitation, reasonable fees, office charges and expenses of counsel to
TCW and Portfolio, Milbank, Tweed, Hadley & McCloy LLP), (b) relating to
printing the instruments evidencing the TCW Sub Notes, (c) relating to any
amendments, waivers or consents under this Agreement to the same extent as set
forth in clause (a) and (b) above, (d) relating to the filing, recording,
refiling and re-recording of any Note Purchase Documents and any other documents
or instruments or further assurances required to be filed or recorded or refiled
or re-recorded by the terms of any Note Purchase Document, or any other event
with respect to which Inland shall have the right to recover from any party
expenses or costs paid or reimbursed to Holders, (e) incident to the enforcement

The Companies shall pay such costs and expenses, to the extent then payable, on

described in clauses (b) through (f) above, thereafter from time to time upon
demand by TCW upon presentation, in each such case, of a reasonably detailed
statement thereof. The Companies' obligations under this SECTION 11.15 shall
survive the payment of the TCW Sub Notes, but only with respect to expenses
incurred prior to payment in full of the TCW Sub Notes and any other obligations
under the Note Purchase Documents.

                  11.16    SPECIFIC PERFORMANCE. The Companies recognize that
money damages may be inadequate to compensate the Holders for a breach by the
Companies of their obligations hereunder, and the Companies irrevocably agree
that the Holders shall be entitled to the remedy of specific performance or the
granting of such other equitable remedies as may be awarded by a court of
competent jurisdiction in order to afford the Holders the benefits of this
Agreement and that the Companies shall not object and hereby waive any right to
object to such remedy or such granting of other equitable remedies on the
grounds that money damages will be sufficient to compensate the Holders.
