ITEM 4.           PURPOSE OF TRANSACTION.

1.  General

                  On August 31, 2000, the CGLH Partnerships entered into a
Securities Purchase Agreement with the Company (the "Securities Purchase
Agreement"). The discussion of the Securities Purchase Agreement herein is
qualified entirely by reference to copy of the Securities Purchase Agreement
attached hereto as Exhibit 2. Pursuant to the Securities Purchase Agreement the
CGLH Partnerships agreed to purchase, for an aggregate purchase price (the
"Purchase Price") of $30,000,000, subject to approval by the stockholders of the
Company and other customary closing conditions, (i) an aggregate of 500,000
shares of the Company's Series B Convertible Preferred Stock, par value $0.01
per share (the "Preferred Stock") and (ii) 8.75% Convertible Subordinated Notes
(the "Notes") having an aggregate principal amount of $25,000,000. Each of the
Preferred Stock and the Notes are convertible at any time, subject to certain
restrictions, into shares of the Company's Class A Common Stock at a conversion
rate of $4.00 per share, subject to anti-dilution adjustments.

                  The issuance of the Preferred Stock and the Notes, together
with the execution of a Registration Rights Agreement, an Investor Agreement,
and the formation of a joint venture with the Company, all described herein, is
expected to occur promptly after receipt of approval by the Company's
stockholders of the issuance of the Preferred Stock, the Notes and the shares of
Class A Common Stock issuable upon conversion of the Preferred Stock and the
Notes, assuming the satisfaction of the other conditions set forth in the
Securities Purchase Agreement.

                  $25,000,000 of the proceeds raised by the sale of the Notes
and the Preferred Stock will be invested by the Company in a newly formed joint
venture (the "Joint Venture") with affiliates of the CGLH Partnerships for
acquisition of hotel properties that will be managed by the Company. Affiliates
of the CGLH Partnerships have committed to invest $20,000,000 of additional
capital to the Joint Venture. A copy of the Form of Joint Venture Agreement is
attached hereto as Exhibit 3.

                  The principal terms and conditions of the securities to be
acquired by the CGLH Partnerships are set forth in the Securities Purchase
Agreement, and in the Form of Articles Supplementary and Form of 8.75%
Subordinated Convertible Note which are Exhibits thereto, and which are
described in greater detail under Item 6, below. The Form of Articles
Supplementary is attached as Exhibit 5 hereto, and the Form of 8.75%
Subordinated Convertible Note is attached as Exhibit 6 hereto. Pursuant to an
Investor Agreement, there will be certain restrictions on the rights of the CGLH
Partnerships to transfer their securities and to take certain actions in respect
of the Company.


                                      -26-
<PAGE>   24

2.  Payment-in-kind Dividends on the Preferred Stock

                  The Preferred Stock accrues cumulative dividends payable in
cash at the rate of 8.75% of the stated amount ($10 per share) on a quarterly
basis, with up to 25% of the dividends payable in additional shares of Preferred
Stock at the Company's option. Accordingly, for so long as any shares of
Preferred Stock are outstanding the Company may elect to issue additional shares
of Preferred Stock to the CGLH Partnerships or other holders of shares of
Preferred Stock.

3.  Payment-in-kind Interest on the Notes

                  The Notes accrue interest on a daily basis at a rate of 8.75%
per annum, compounded quarterly. Interest on the Notes is payable in cash;
however, up to 25% of the interest owed on any interest payment date is payable
by a payment-in-kind Note at the Company's option. Accordingly, for so long as
any Note is outstanding the Company may elect to issue additional Notes to the
CGLH Partnerships or other holders of the Notes.

4.  Right to appoint Directors

                  Pursuant to the Investor Agreement to be entered into at the
Closing between the Company and the CGLH Partnerships, a copy of which is
attached as Exhibit 4 hereto, the number of directors on the Board of Directors
of the Company will be increased to eleven. The CGLH Partnerships will have the
right to appoint up to five directors to the Board of Directors of the Company.

4.  Intentions of Reporting Persons

                  The CGLH Partnerships intend to continually evaluate the
business, prospects and financial condition of the Company, the market for the
Common Stock, other opportunities available to the CGLH Partnerships, general
economic conditions, money and stock market conditions and other factors and
future developments which the CGLH Partnerships may deem relevant from time to
time. Depending on such factors, the CGLH Partnerships may decide to sell all or
part of the interests they hold. Any such acquisition or disposition of Common
Stock may be effected through open market or privately negotiated transactions,
or otherwise.

                  The Lehman Investors intend to continually evaluate the
business, prospects and financial condition of the Company, the market for the
Common Stock, other opportunities available to the Lehman Investors, general
economic conditions, money and stock market conditions and other factors and
future developments which the Lehman Investors may deem relevant from time to
time. Depending on such factors, the Lehman Investors may decide to sell all or
part of the interests they hold. Any such acquisition or disposition of Common
Stock may be effected through open market or privately negotiated transactions,
or otherwise.

                  The CG Investors intend to continually evaluate the business,
prospects and financial condition of the Company, the market for the Common
Stock, other opportunities available to the CG Investors, general economic
conditions, money and stock market conditions and other factors and future
developments which the CG Investors may deem relevant from time to time.
Depending on such factors, the CG Investors may decide to sell all or part of
the interests they hold. Any such acquisition or disposition of Common Stock may
be effected through open market or privately negotiated transactions, or
otherwise.

<PAGE>   25

                  The shares of Common Stock of the Company beneficially owned
by each of Messrs. Weiser, Lefton and Alibhai immediately prior to August 31,
2000 were acquired by such individuals for long-term investment purposes.

                  The KFP Investors intend to continually evaluate the business,
prospects and financial condition of the Company, the market for the Common
Stock, other opportunities available to the KFP Investors, general economic
conditions, money and stock market conditions and other factors and future
developments which the KFP Investors may deem relevant from time to time.
Depending on such factors, the KFP Investors may decide to sell all or part of
the interests they hold. Any such acquisition or disposition of Common Stock may
be effected through open market or privately negotiated transactions, or
otherwise.

                  Except as set forth above in this Item 4, none of the CGLH
Partnerships, the Lehman Investors, the CG Investors, and the KFP Investors have
any specific plans or proposals that relate to or would result in any of the
actions specified in clauses (a) through (j) of Item 4 of Schedule 13D.

ITEM 5.         INTERESTS IN SECURITIES OF THE ISSUER.

                  (a) The information contained in Items 11 and 13 of each of
the cover pages to this Schedule 13D are incorporated herein by reference.

                  Based on the information disclosed by the Company in the
Securities Purchase Agreement, as of August 31, 2000, there were 6,091,802
shares of Common Stock issued and outstanding.

                  Pursuant to the Securities Purchase Agreement, at the closing
(the "Closing", which is to occur as promptly as practicable following the
satisfaction or waiver of all of the conditions to closing set forth in the
Securities Purchase Agreement) the GCLH Partnerships will acquire securities
which are initially convertible into shares of Common Stock at a conversion
price of $4.00 per share. The terms of the Notes and the Preferred Stock
prohibit any single holder from converting such securities if the conversion
would cause such holder and its affiliates or any group of which any of them is
a member to have beneficial ownership of more than 49% of the Company's Class A
Common Stock after the conversion. Accordingly, if the number of issued and
outstanding shares of Common Stock is otherwise unchanged at the Closing, and
affiliates of or any group of which the CGLH Partnerships are a member continue
to beneficially own the 74,262 shares of Common Stock directly owned such group
members at the date hereof, the CGLH Partnerships will not then have the right
to convert the Notes and the Preferred Stock into more than 5,778,646 shares of
Common Stock. Absent this restriction, the Notes and Preferred Stock would be
initially convertible into an aggregate of 7,500,000 shares of Common Stock,
representing approximately 55.2% of the outstanding shares of Common Stock after
giving effect to the conversion. In addition, if all or part of the Notes and
Preferred Stock are transferred to unaffiliated persons so that no single person
and its affiliates would, upon conversion, own more than 49%, then 7,500,000
shares of Common Stock would be issuable upon conversion of the Notes and the
Preferred Stock.

                  The Lehman Investors disclaim beneficial ownership of the
shares of Common Stock beneficially owned by the CGLH Partnerships to the extent
of the interests in the CGLH



                                      -28-
<PAGE>   26

Partnerships held by persons other than the Lehman Investors. Lehman Brothers
Inc., a wholly owned broker-dealer subsidiary of Lehman Brothers Holdings Inc.,
and other affiliates acting in the ordinary course of business as broker
dealers, may have purchased and sold shares of Common Stock on behalf of their
customers.

                  The CG Investors disclaim beneficial ownership of the shares
of Common Stock beneficially owned by the CGLH Partnerships to the extent of the
interests in the CGLH Partnerships held by persons other than the CG Investors.

                  The KFP Investors disclaim beneficial ownership of the shares
of Common Stock beneficially owned by the CGLH Partnerships to the extent of the
interests in the CGLH Partnerships held by persons other than the KFP Investors.

                  None of the Reporting Persons or, to the knowledge of the
Reporting Persons, the persons listed on Schedules A to D hereto beneficially
owns any shares of Common Stock other than as set forth herein.

                  (b) The information contained in Items 7, 8, 9 and 10 of each
of the cover pages to this Schedule 13D are incorporated herein by reference.
With respect to the Lehman Investors, neither the Lehman Investors nor to the
best knowledge of the Lehman Investors any of the persons listed in Schedules A
through C hereto know of any other person who has the right to receive or the
power to direct the receipt of, any shares of Common Stock beneficially owned by
the Lehman Investors, other than customers of Lehman Brothers over whose shares
Lehman Brothers may have investment discretion.

                  (c) Except as described in Item 4 of this Schedule 13D, no
transactions in the shares of Common Stock were effected by the Reporting
Persons, or, to their knowledge, any of the persons listed on SCHEDULES A
THROUGH D hereto, during the past sixty days.

                  (d) and (e)       Not applicable.


ITEM 6.           CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS
                  WITH RESPECT TO SECURITIES OF THE ISSUER.

                  The responses set forth in Items 3, 4 and 5 of this Schedule
13D are incorporated herein by reference.

1.       Securities Purchase Agreement

                  The following is a summary of certain terms of the Securities
Purchase Agreement, and is qualified entirely by reference to the Securities
Purchase Agreement, which is attached hereto as Exhibit 2.

                  The Securities Purchase Agreement sets forth the terms on
which the CGLH Partnerships will make the $30,000,000 investment in the Company.
The Securities Purchase Agreement was executed by the Company and the CGLH
Partnerships on August 31, 2000. It is the document by which the Company agreed
to issue, and the CGLH Partnerships agreed to purchase, the Notes and the
Preferred Stock.



                                      -29-
<PAGE>   27

                  It contains certain representations and warranties of both the
Company and the CGLH Partnerships which are customary in transactions of this
nature. It also includes a number of conditions which must be satisfied or
waived before the Closing can occur, including:

     o   Approval by the Company's stockholders of the issuance of the Preferred
         Stock, the Notes and the shares of Common Stock issuable upon
         conversion of the Preferred Stock and the Notes;

     o   Approval by NASDAQ of the quotation, subject to official notice of
         issuance, of the shares of Common Stock issuable upon conversion of the
         Preferred Stock and the Notes

     o   Execution by the parties of the Investor Agreement, the Registration
         Rights Agreement and the Joint Venture Agreement;

     o   Amendment of the Company's charter to designate the rights and
         preferences of the Preferred Stock; and

     o   Receipt by the CGLH Partnerships of opinions of counsel to the Company,
         a certificate of an officer of the Company and a Secretary's
         certificate certifying certain matters.

                  The Securities Purchase Agreement provides for its termination
prior to the Closing by either the CGLH Partnerships or the Company in certain
circumstances, including material breach by the other party of such party's
representations or warranties which would result in a failure to satisfy the
conditions to Closing. Upon such a termination by the CGLH Partnerships, and
upon a termination in certain other limited circumstances, the Company will pay
to the CGLH Partnerships a termination fee of $2,250,000. In addition, upon a
termination the Company may be liable to pay to the CGLH Partnerships their
reasonable documented fees and expenses up to a maximum of $2,250,000. The
agreement will terminate automatically if the Closing does not occur on or
before October 16, 2000, subject to extension by the Company, by payment of a
fee, to either November 15, 2000 or November 30, 2000.

2.       Investor Agreement

                  The following is a summary of certain terms of the Investor
Agreement, and is qualified entirely by reference to the Form of Investor
Agreement attached hereto as Exhibit 4.

                  Pursuant to the terms of the Investor Agreement, for a period
of either three of four years (depending on the type of transaction) following
the Closing (or until the holdings of the CGLH Partnerships or their affiliates
or related transferees decrease below a certain level, or the market price of
the Common Stock reaches a certain level), the security holders are prohibited
from engaging in certain transactions with respect to the voting securities of
the Company, including certain acquisitions or dispositions of stock of the
Company and certain actions with respect to the election of directors of the
Company.

                  For so long as the foregoing restrictions apply, the CGLH
Partnerships may not sell, transfer or dispose of its investment other than at a
date after 6 months following the purchase of the Notes and Preferred Stock:



                                      -30-
<PAGE>   28

     o   under the Registration Rights Agreement;

     o   under Rule 144, so long as the disposition is not made to any person
         who would thereafter own 12.5% of the Total Voting Power (as defined in
         the Investor Agreement) (or 20% in the case of institutional
         investors); and

     o   to any person that would not thereafter own 12.5% of Total Voting Power
         (or 20% in the case of certain institutional investors).

3.       The Notes

                  The following is a summary of certain terms of the Notes, and
is qualified entirely by reference to the Form of 8.75% Subordinated Convertible
Notes attached hereto as Exhibit 6 and, as applicable, to the Form of Investor
Agreement attached hereto as Exhibit 4.

                  Principal Amount, Maturity and Interest. The principal amount
of the Notes is $25 million. The Notes mature seven years after the Closing and
accrue interest on a daily basis at a rate of 8.75% per annum, compounded
quarterly. Interest on the Notes is payable in cash; however, up to 25% of the
interest owed on any interest payment date is payable by a payment-in-kind Note
at the Company's option. The terms of the Notes provide that during the
continuance of an event of default, the Notes accrue interest at a default
interest rate per annum of 10.75%.

                  Conversion. The Notes and any paid-in-kind Notes issued
instead of interest on the Notes are convertible at any time into shares of the
Company's Class A Common Stock at a conversion rate of $4.00 per share, subject
to anti-dilution adjustment. The terms of the Notes prohibit any holder from
converting the Notes if the conversion would cause the holder and its affiliates
or any group of which any of them is a member to have beneficial ownership of
more than 49% of the Company's Class A Common Stock after the conversion.
Subject to that restriction, on the date of issuance, the Notes will be
convertible into 6,250,000 shares of the Company's Class A Common Stock.

                  Redemption. In addition, upon a Change in Control (as defined
in the Notes) the Company has an obligation to offer to the Holders, and the
Holders have the right to require the Company to redeem the Notes for cash equal
to the greater of:

     o   the principal amount of the Notes plus accrued interest through the
         date of redemption; or

     o   the fair market value of the cash securities and other property that
         the Holder could have received had it converted its Notes, plus accrued
         interest payable in cash.

                  Holders of the Notes may elect not to have their Notes
redeemed.

                  Events of Default. The following events constitute defaults by
the Company which will accelerate the maturity of the Notes:

     o   principal or interest payment default on any of the Notes;

     o   a bankruptcy filing by the Company or the filing of a petition to
         declare the Company bankrupt that has not been discharged within 60
         days;


                                      -31-
<PAGE>   29

     o   acceleration of at least $1.5 million of the Company's indebtedness;

     o   material breach by the Company of its obligations under the Notes or of
         its obligation to nominate to the Board of Directors any designee of
         the CGLH Partnerships under the Investor Agreement, which remains
         uncured for 15 days after notice to the company; or

     o   final judgement against the Company in excess of $1.5 million which
         remains unsatisfied for 30 days after entry of such judgement.

                  Holders of more than 50% of the Notes may annul the
acceleration of the maturity of the Notes, if all interest due on the Notes is
duly paid and every event of default is cured or waived.

                  Subordination. Payments under the Notes are subordinated to
payments on all other senior indebtedness of the Company. Upon receipt by the
Company of a notice of default relating to senior indebtedness, for a period of
90 days after such notice (the "Payment Blockage Period"), the Company shall not
pay principal or interest on the Notes or redeem such Notes until the senior
indebtedness has been paid in full or the default is no longer continuing. The
Payment Blockage Period applies while any of the Notes are outstanding after
certain events described in the Investor Agreement have occurred, and shall not
restrict the holder's conversion rights. There are no limitations on the
issuance of additional senior indebtedness by the Company, other than the
obligation to obtain the consent of the Required Holders (as defined below) for
the incurrence of debt in general exceeding specified amounts.

                  Restrictions while Notes are Outstanding. For so long as the
Notes are outstanding, the Company agrees not to engage in the following
activities without the prior written consent of the holders of at least a
majority of the combined voting power of the Notes and the Preferred Stock
outstanding (the "Required Holders"):

     o   enter into a Change in Control transaction or merge with an entity
         other than a wholly-owned subsidiary;

     o   enter into an agreement which materially restricts the Company's
         performance of its obligations under its agreements with the CGLH
         Partnerships;

     o   grant any registration rights regarding the Company's securities which
         have an aggregate value in any year exceeding the lesser of certain
         specified amounts and 5% of the Company's market capitalization;

     o   amend the Company's charter, the Notes or bylaws in a manner that
         adversely affects the rights of the CGLH Partnerships; or

     o   redeem any securities of the Company without also offering to redeem
         the Notes (except for redemptions of the Company's Class C Common Stock
         or the Preferred Stock).

                  In addition, until certain conditions are met, the Company
must obtain the prior written consent of the Required Holders before taking
certain other actions described in the Investor Agreement.

                  Amendments. Amendments to the provisions of the Notes must be
approved by the Required Holders.

4.       The Preferred Stock

                  The following is a summary of certain terms of the Preferred
Stock, and is qualified entirely by reference to the Form of Articles
Supplementary attached hereto as Exhibit 5 and, as applicable, to the Form of
Investor Agreement attached hereto as Exhibit 6.

                  Dividends. The terms of the Preferred Stock are substantially
the same as the Notes, except as noted below. The Preferred Stock accrues
cumulative dividends payable in cash at the rate of 8.75% of the stated amount
($10 per share) on a quarterly basis, with up to 25% of the dividends payable in
additional shares of Preferred Stock at the Company's option. If the dividends
are in arrears for a period of 60 days or more, then an additional cumulative
dividend accrues at an annual rate of 2% of the stated amount ($10 per share)
payable in shares of Preferred Stock. The Preferred Stock also receives any
dividends paid to holders of Class A Common Stock of the Company on an
as-converted basis. The Company is precluded from paying dividends on or
repurchasing capital stock that is on parity with the Preferred Stock and from
repurchasing capital stock that is not ranked senior to the Preferred Stock,
unless all dividends accrued on the Preferred Stock have been paid.

                  Voting Rights. The Preferred Stock has the right to elect up
to five members to the Company's Board of Directors as described above under the
Investor Agreement. In addition, if the Company fails to pay dividends on the
Preferred Stock or interest on the Notes for six quarterly periods, then the
size of the Company's Board increases to thirteen directors and the CGLH
Partnerships are entitled to elect seven of the thirteen directors until such
time as the payment default has been cured. Other than for these rights and the
rights described under the discussion of "Restrictions While Preferred Stock is
Outstanding" below, the Preferred Stock has no voting rights.

                  Conversion. Each share of Preferred Stock, including any
shares issued of Preferred Stock issued instead of dividends, is convertible at
any time at the option of the holder into Class A Common Stock of the Company,
whether or not the Company has given notice of redemption. The conversion price
is $4.00 per share of Class A Common Stock subject to anti-dilution adjustment.

                  Restrictions While Preferred Stock is Outstanding. For so long
as the Preferred Stock is outstanding, the Company agrees not to engage in the
following activities without the prior written consent of the Required Holders:

     o   authorize, create, reclassify or issue any senior stock or parity stock
         or any stock convertible into senior or parity stock;

     o   amend any rights of the holders of the Preferred Stock or the Class B
         or Class C Common Stock;

     o   amend the rights of the Class A Common Stock in a manner adverse to the
         holders of the Preferred Stock;

     o   enter into a Change in Control transaction or merge with an entity
         other than a subsidiary;


                                      -33-
<PAGE>   31

     o   enter into an agreement which materially restricts the Company's
         performance of its obligations under its agreements with the CGLH
         Partnerships;

     o   grant any registration rights regarding the Company's securities which
         have a value in any year exceeding the lesser of certain specified
         amounts and 5% of the Company's market capitalization;

     o   amend the Company's charter, bylaws or the Notes in a manner that
         adversely affects the rights of the CGLH Partnerships; or

     o   redeem any securities of the Company without also offering to redeem
         the Preferred Stock (except for redemptions of the Company's Class C
         Common Stock or the Notes).

                  In addition, until certain conditions are met, the Company
must obtain the prior written consent of the Required Holders before taking
certain other actions described in the Investor Agreement.

                  Redemption Rights. The Company has an obligation to redeem the
Preferred Stock on the seventh anniversary of the issuance of the Preferred
Stock to the CGLH Partnerships. The redemption price will be $10 per share plus
all accrued dividends on the date of redemption. The Company is not required to
provide notice of such redemption to the holders of Preferred Stock. The holders
of the Preferred Stock may convert their shares of the Preferred Stock at any
time prior to the redemption date. There is no restriction on the redemption of
the Preferred Stock by the Company while the Company is in arrearage in the
payment of dividends. In addition, upon a Change in Control, the Company has an
obligation to offer to the holders of Preferred Stock, and the holders of
Preferred Stock may require from the Company to redeem the Preferred Stock on
the same basis as the Notes described above.

                  Liquidation Preference. Upon issuance, the Preferred Stock
will have an aggregate liquidation preference of $5,000,000. Upon a liquidation
of the Company the holders of Preferred Stock will be entitled to receive the
greater of (a) $10 per share plus any accrued dividends, and (b) the fair market
value of the cash, securities and other property that the holder of Preferred
Stock would have received had it converted, its Preferred Stock plus accrued
dividends.

                  Restriction on Conversion. The terms of the Preferred Stock
prohibit any single holder from exercising the right to convert any shares of
Preferred Stock if the conversion would cause the holder and its affiliates or
any group of which any of them is a member to have beneficial ownership of more
than 49% of the Company's Class A Common Stock after the conversion. Subject to
that restriction, on the date of issuance, the shares of Preferred Stock will be
convertible into, 1,250,000 shares of the Company's Class A Common Stock on the
date of issuance.

5.       The Registration Rights Agreement

                  The Registration Rights Agreement, to be entered into between
the Company and the CGLH Partnerships at the Closing (the "Registration Rights
Agreement") is attached hereto as Exhibit 7 and is incorporated in and made a
part of this Schedule 13D in its entirety by reference.


                                      -34-
<PAGE>   32

                  The Registration Rights Agreement provides, subject to the
limitations described therein, (i) the CGLH Partnerships have an unlimited right
to include their Notes, Preferred Stock (and the shares of Class A Common Stock
of the Company into which they are convertible) in a registration by the
Company; (ii) subject to the limitations on sales described in the Investor
Agreement, the CGLH Partnerships may, on seven occasions, make a demand for
registration of their Notes, Preferred Stock (and the shares of Class A Common
Stock of the Company into which they are convertible), so long as such demand
includes at least 500,000 shares or such lesser number of shares as would yield
gross proceeds of at least $2 million; (iii) the Company shall not to grant
registration rights to any other party that would limit the CGLH Partnerships'
priority for the sale or distribution of securities in connection with a demand
registration; and (iv) the CGLH Partnerships have the right to receive the most
favorable registration rights the Company makes available to any person in
connection with the registration of securities and the Registration Rights
Agreement is automatically amended to reflect such favorable terms upon grant.

6.       Stockholders Agreement

                  On August 31, 2000 the CGLH Partnerships entered into a
Stockholders Agreement with Thomas F. Hewitt, J. William Richardson and Kevin P.
Kilkeary (together the "Executives"). A copy of that agreement is annexed hereto
as Exhibit 8 and is incorporated in and made a part of this Schedule 13D in its
entirety by reference.

                  Pursuant to the Stockholders Agreement, the Executives granted
to the CGLH Partnerships an irrevocable proxy to vote certain shares of
Preferred Stock which will be granted to the Executives by the Company at the
time of Closing. The CGLH Partnerships do not have any rights in respect of the
shares of Common Stock issuable upon conversion of such shares of Preferred
Stock.

7.       Other matters

                  Other than as set forth in this Item 6 and Items 3, 4, and 5
above, none of the Reporting Persons is a party to any contract, arrangement,
understanding or relationship with respect to any securities of the issuer, and
none of the securities as to which this Schedule 13D relates is pledged or is
otherwise subject to a contingency the occurrence of which would give another
person voting power or investment power over such securities.

Business as presently conducted and as proposed by it to be conducted. The
Company has all requisite Power to enter into and carry out the transactions

approval of the Stockholder Proposal. No other approval or consent of the
stockholders of the Company is required by Law, the Charter or bylaws of the
Company or otherwise in order for the Company to consummate the transactions
contemplated hereby and by the Ancillary Documents. Each of this Agreement and
the Ancillary Documents constitutes a legal, valid and binding obligation of the
Company, enforceable against the Company in accordance with its terms except to
the extent that enforceability may be limited by bankruptcy, solvency or other
similar laws affecting creditors' rights generally and subject to limitations on
the availability of equitable remedies (the foregoing exception, the "Bankruptcy
Exception"). The Board of Directors of the Company, at a meeting duly called and
held at which a quorum was present throughout, has unanimously determined that

other governmental body applicable to it, or any of its Subsidiaries or any of
their respective properties or assets, (b) conflict with, or result in any
violation or breach of, or constitute (with due notice or lapse of time, or

or cancellation under, the terms, conditions or provisions of any Contract to
which it or any of its Subsidiaries is a party to which any of their respective

of any of the terms or provisions of such leases or has received notice of the
assertion of any claim adverse to its rights as lessee under such leases, or

power of such holders is set forth on Schedule 3.1 hereto, provided that such
Schedule 3.1 shall exclude Lehman Parent Entities other than LB Interstate GP
LLC and LB Interstate LP LLC. Other than as disclosed to the Company in writing
or pursuant to agreements of Lehman Parent Entities (other than LB Interstate GP
LLC or LB Interstate LP LLC) or as permitted in the limited partnership
agreements of entities comprising the Purchaser, the Purchaser is not a party to
any options, subscription rights, calls, commitments of any character whatsoever
relating to, the equity interests in the Purchaser or any other contract
agreement or arrangement, whether oral or written (and any amendments,

an equity interest in the Purchaser or to obtain voting control over such equity
interests. The Purchaser has made available to the Company for its review true,
correct and complete copies of the formation documents and operating agreements
of the Purchaser and any amendments or supplements thereto.

     3.2. Authorization of the Documents. The execution, delivery and
performance by the Purchaser of this Agreement, and each of the Ancillary
Documents to which it is a party has been duly authorized by all requisite
corporate action on the part of the Purchaser and do not or will not require the
approval or consent of the partners of the Purchaser. Each of this Agreement and
the Ancillary Documents constitutes a legal, valid and binding obligation of the
Company, enforceable against the Company in accordance with its terms except to
the extent that enforceability may be limited by the Bankruptcy Exception.

     3.3. No Conflict. The execution and delivery by the Purchaser of the
Agreement and each of the Ancillary Documents to which it is a party and the
consummation by the Purchaser of the transactions contemplated hereby and
thereby and its compliance with the provisions hereof and thereof will not (a)
violate any provision of any federal, state, local or foreign law, statute, rule
or regulation, or any ruling, writ, injunction, order, judgment or

of the transactions contemplated hereby or thereby.

the Notes and the Series B Preferred Stock and the Conversion Shares for its own
account for investment purposes and not as a nominee or agent, and not with a

applicable securities laws. The Purchaser has no present intention of selling,
granting any participation in, or otherwise distributing the same other than as

investment in the Company.

     3.7 Restrictions on Transfer. The Purchaser understands that the Notes and
the Series B Preferred Stock and the Conversion Shares will be characterized as
"restricted securities" under the federal securities laws inasmuch as they are
being or will be acquired from the Company in a transaction not involving a
public offering and that under such laws and applicable regulations such
securities may be resold without registration under the Act only in certain
limited circumstances. In this connection, the Purchaser represents that it is
familiar with Rule 144 under the Securities Act, as presently in effect, and

for the Notes (the "Note Register"), in which the Company shall record the name
and address of the Person in whose name each Note has been issued and the name
and address of each transferee and prior owner of each Note. The Company may
deem and treat the Person in whose name a Note is so registered as the holder

exchange or registration of transfer of any Note at the office of the Company
designated for notices in accordance with Section 14 of this Agreement, the
Company shall execute and deliver, at its expense, one or more new Notes
substantially in the form of Exhibit A as requested by the Holder of the
surrendered Note, each dated the date to which interest has been paid on the
Note so surrendered (or, if no interest has been paid, the date of such
surrendered Note), but in the same aggregate unpaid principal amount as such
surrendered Note, and registered in the name of such Person or Persons as shall
be designated in writing by such holder. Every Note surrendered for registration
of transfer shall be duly endorsed, or be accompanied by a written instrument of
transfer duly executed, by the Holder of such Note or by his attorney duly

a bank or brokerage firm. The Company may also condition the issuance of any new
Note or Notes to a Person other than the Holder thereof on the payment of a sum
sufficient to cover any stamp tax or other governmental charge imposed in
respect of such transfer. Notes shall be transferred in denominations of $1,000

registration of transfer by a Holder of its entire holding of Notes, one Note
may be in a denomination of any amount.

regard to its ongoing operations, to the assets, properties, offices and other
facilities, Contracts and books and records of the Business and of the Company
and its Subsidiaries, and to the outside auditors of the Company and their work
papers relating thereto, in each case, as the Purchaser may from time to time
reasonably request, provided, however, that the Company shall not be required to
provide access to, or disclose, information where such access or disclosure
would contravene applicable laws, rules, regulations, orders or decrees or
result in the waiver of the attorney-client privilege or the protection afforded

cause its respective officers, employees, accountants, counsel, financial
advisors and other representatives and Affiliates to hold, any nonpublic
information in confidence in accordance with Section 3.5 of the Investor

Series B Preferred Stock by means of any form of general solicitation or general
advertising (as those terms are used in Regulation D under the Securities Act)
or in any manner involving a public offering within the meaning of Section 4(2)
of the Securities Act that would require the registration of any Note or the
Series B Preferred Stock under the Securities Act unless the Note or the Series
B Preferred Stock, as applicable, is so registered or (ii) take any other action
which could reasonably be expected to require the registration under any
securities Laws of the issuance of the Notes, the shares of Series B Preferred
Stock provided for herein or the sale of any such Notes or shares of Series B

been, or will be prior to receiving any information furnished to the Purchaser
pursuant to this Section 5.4, advised by the Purchaser that applicable
securities laws may prohibit any person who has material, non-public information
from purchasing or selling securities of the Company or from communicating the
information to any other person or entity.

     5.7. No Solicitation of Competing Transactions.

     (a) Except as expressly permitted in writing by the Purchaser, the Company
shall not, nor shall it authorize or permit any of its Subsidiaries or any of
the Company's or any Subsidiary's directors, officers, employees,
representatives, agents and advisors (including any investment banker, financial
advisor, attorney, accountant or other representative retained by any of them),
directly or indirectly, to (i) solicit, initiate, encourage (including by way of
furnishing nonpublic information), respond to (other than by bare statement,
without any further detail or explanation, that they are not permitted to
respond), or take any other action designed to facilitate, any inquiries or the
making of any proposal by a third party (a "Third Party") with respect to any
merger, consolidation, transfer of material assets, sale or exchange of
securities or similar transaction (collectively, a "Competing Transaction"),
(ii) participate in any substantive discussions or negotiations regarding any
Competing Transaction or (iii) enter into any letter of intent, agreement in

foregoing.

     (b) Notwithstanding anything to the contrary in this Agreement, (i) the
Company may, in response to an unsolicited written offer or proposal with
respect to a potential or proposed Competing Transaction engage in negotiations
or discussions with, or provide information or data to, any Third Party relating
to any Competing Transaction if the Competing Transaction is a Superior
Proposal. Any information furnished to any Third Party in connection with any
Competing Transaction shall be provided pursuant to a confidentiality and
standstill agreement on customary terms (including without limitation
prohibitions on unsolicited tender offers, acquisitions of equity interests in
the Company, proposals to acquire stock or assets, formation of Section 13(d)
groups, public request for release from the standstill, actions that would
require the Company to make a public announcement, engaging in proxy contests,
etc.).

     (c) The Company shall promptly (but in any event by the next business day)
advise the Purchaser in writing of any inquiries, discussions, negotiations,
proposals or requests for information received on or after the date of this
Agreement relating to any Competing Transaction, the material terms and
conditions thereof and the identity of the person making such request or
proposing such Competing Transaction. The Company shall promptly advise the
Purchaser of any development on or after the date hereof relating to any
inquiries, discussions, negotiations, proposals or requests for information
relating to a Competing Transaction, whether the original inquiries,
discussions, negotiations, proposals or requests for information occurred
before, on or after the date of this Agreement.

     (d) In the event the Board of Directors of the Company has determined that
a potential or proposed Competing Transaction constitutes a Superior Proposal
that the Company intends to accept, the Company shall promptly deliver to the
Purchaser notice thereof and of its intention to terminate this Agreement not
fewer than five business days after delivery of such notice. After such five
business day period, the Board of Directors of the Company may then (and only
then) terminate this Agreement and enter into an agreement with respect the
Superior Proposal.

     (e) "Superior Proposal" means any bona fide written offer made by a Third
Party to acquire, directly or indirectly, for consideration consisting of cash
and/or securities, all of the shares of Common Stock, Class B Common Stock and
Class C Common Stock then outstanding (i) at a price greater than $4.00 per
share and (ii) that constitutes a transaction that, in the judgment of the Board
of Directors of the Company, is reasonably likely to be consummated on the terms
set forth, taking into account all legal, financial, regulatory and other
aspects of such proposal.

     (f) Nothing contained in this Agreement shall prohibit the Company from
taking and disclosing to its stockholders a position contemplated by Rule
14e-2(a) promulgated under the Securities Exchange Act of 1934 or from making
any disclosure to the Company's stockholders (including with respect to the
delivery by the Company to the Purchaser of a Notice of Superior Proposal) if,
in the judgment of the Board of Directors of the Company, after consultation
with outside counsel, failure so to disclosure would be inconsistent with its
obligations under applicable law.

     5.8. Stockholder Approval; Proxy Statement. (a) Subject to the terms and
conditions contained herein, the Company shall submit the proposed issuance of
Common Stock in the transactions contemplated hereby (the matter submitted, the
"Stockholder Proposal") for approval to the holders of shares of Common Stock,
Class B Common Stock and Class C Common Stock, voting together as a single
class, at a meeting to be duly held for this purpose by the Company (the
"Company Meeting"). The Company shall take all action in accordance with the
federal securities Laws, the Maryland General Corporations Law, its Charter and
Bylaws necessary to duly convene the Company Meeting, and shall use its
reasonable best efforts to hold such meeting as soon as reasonably practicable
after the date hereof.

     (b) The Company shall, as soon as practicable, prepare and file a
preliminary Proxy Statement (such proxy statement, and any amendments or
supplements thereto, the "Proxy Statement") with the SEC with respect to the
Company Meeting and shall use its reasonable efforts to respond to any comments
of the SEC or its staff and to cause the Proxy Statement to be cleared by the
SEC as soon as practicable. The Proxy Statement shall include the Board
Recommendation. The Company shall notify the Purchaser of the receipt of any
comments from the SEC or its staff and of any request by the SEC or its staff
for amendments or supplements to the Proxy Statement or for additional
information and shall supply the Purchaser with copies of all correspondence
between the Company or any of its representatives, on the one hand, and the SEC
or its staff, on the other hand, with respect to the Proxy Statement of the
transactions contemplated hereby. The Company shall give the Purchaser and its
counsel (who shall provide any comments thereon as soon as practicable, and the
Company shall incorporate any such comments that are reasonable into the Proxy
Statement) the opportunity to review the Proxy Statement prior to its being
filed with the SEC and shall give the Purchaser and its counsel (who shall
provide any comments thereon as soon as practicable, and the Company shall
incorporate any such comments that are reasonable into the Proxy Statement) the
opportunity to review all amendments and supplements to the Proxy Statement and
all responses to requests for additional information and replies to comments
prior to their being filed with, or sent to, the SEC. Each of the Company and
the Purchaser agrees to use its reasonable efforts, after consultation with the
other parties hereto, to respond promptly to all such comments of and requests
by the SEC. As promptly as practicable after the Proxy Statement has been
cleared by the SEC, the Company shall mail the Proxy Statement to the
stockholders of the Company. If at any time prior to the approval of the
Stockholder Proposal by the Company's stockholders there shall occur any event
that should be set forth in an amendment or supplement to the Proxy Statement,
the Company shall prepare and mail to its stockholders such an amendment or
supplement.

     (c) The Company represents and warrants that the Proxy Statement will
comply as to form in all material respects with the Exchange Act and, at the
respective times filed with the SEC and distributed to stockholders of the
Company, will not contain any untrue statement of a material fact or omit to
state any material fact required to be stated therein or necessary in order to
make the statements therein, in the light of the circumstances under which they
were made, not misleading; provided, that the Company makes no representation or
warranty as to any information included in the Proxy Statement which was
provided by the Purchaser. The Purchaser represents and warrants that none of
the information supplied by the Purchaser for inclusion in the Proxy Statement
will, at the respective times filed with the SEC and distributed to stockholders
of the Company, contain any untrue statement of a material fact or omit to state
any material fact required to be stated therein or necessary in order to make
the statements therein, in the light of the circumstances under which they were
made, not misleading.

     5.9 Reasonable Best Efforts. Upon the terms and subject to the conditions
set forth in this Agreement, each of the parties agrees to use its reasonable
best efforts to take, or cause to be taken, all actions, and to do, or cause to
be done, and to assist and cooperate with the other parties in doing, all things
necessary, proper or advisable to consummate and make effective, in the most
expeditious manner practicable, the Closing and the other transactions
contemplated by this Agreement and the Ancillary Documents, including using
reasonable efforts to accomplish the following: (i) the taking of all reasonable
acts necessary to cause the conditions to Closing to be satisfied as promptly as
practicable, (ii) the obtaining of all necessary actions or nonactions, waivers,
consents and approvals from Governmental Entities and the making of all
necessary registrations and filings (including filings with Governmental
Entities, if any) and the taking of all reasonable steps as may be necessary to
obtain an approval or waiver from, or to avoid an action or proceeding by any
Governmental Entity, (iii) the obtaining of all necessary consents, approvals or
waivers from third parties, (iv) the defending of any lawsuits or other legal
proceedings, whether judicial or administrative, challenging this Agreement or
the Ancillary Documents or the

                                      -22-

consummation of the Closing, including seeking to have any stay or temporary
restraining order entered by any court or other Governmental Entity vacated or
reversed and (v) the execution and delivery of any additional instruments
necessary to consummate the Closing and the other transactions contemplated by,
and to fully carry out the purposes of, this Agreement and the Ancillary
Documents. This Section 5.9 shall be deemed not to have been breached by the
Company as a result of any action taken by the Company with respect to a
Superior Proposal that is expressly permitted under Section 5.7.

     SECTION 6.  ADDITIONAL AGREEMENTS.

     6.1 Indenture Relating to the Notes. Upon the written request of the
Holders of at least 51% of the outstanding principal amount of the Notes at the
time outstanding (exclusive of Notes then owned by the Company or any of its
Affiliates) (the "Required Noteholders") in connection with a sale or offering
of the Notes pursuant to the Registration Rights Agreement, the Company, at its
expense, shall cause to be prepared, executed and delivered within 30 days after
such request an indenture (including a new form of note, any necessary related
documentation and, from time to time thereafter, any necessary supplements
thereto) (the "Indenture") with respect to the Notes, which Indenture shall
contain terms and provisions substantially the same as those set forth in
Sections 5, 6 and 7 hereof, and the substantive provisions of the Note,
including but not limited to, redemption, conversion, subordination, and
interest payment, in form and substance no less favorable to the Holders of the
Notes than as set forth in this Agreement and the Note, and such other terms and
provisions as are required under the Trust Indenture Act of 1939 and such other
items and provisions as are customary in indentures relating to publicly traded
senior secured debt securities having such terms. In such event, the Company
shall also appoint as trustee under the Indenture a national banking association
reasonably acceptable to the Required Noteholders having its principal offices
in New York, New York, and having capital, surplus, and undivided profits of at
least $50,000,000. In connection with the execution of the Indenture, the
Holders shall exchange all outstanding Notes for new notes in the form
contemplated by the Indenture, and upon such exchange such new notes shall be
deemed to be "Notes" for purposes hereof.

     6.2. Lost, Stolen, Damaged and Destroyed Securities. Upon receipt of
evidence reasonably satisfactory to the Company of the loss, theft, destruction
or mutilation of any certificate representing shares of Common Stock, Series B
Preferred Stock or a Note and in the case of loss, theft or destruction, upon
delivery of an indemnity satisfactory to the Company (which, in the case of the
Purchaser, may be an undertaking by the Purchaser to so indemnify the Company
and which, in the case of any Person other than the Purchaser, shall be delivery
of an indemnity bond), or, in the case of mutilation, upon surrender and
cancellation thereof, the Company will issue a new share certificate of like
tenor for a number of shares of Common Stock or Series B Preferred Stock, as
applicable, equal to the number of shares of such stock represented by the
certificate lost, stolen, destroyed or mutilated, or a new Note of like tenor in
an amount equal to the amount of such Note lost, stolen, destroyed or mutilated.

     6.3. Transactions with Affiliates. The Company agrees that, so long as any
of the Notes or any shares of Series B Preferred Stock are issued and
outstanding, without the consent of the Required Holders the Company will not,
and will not permit any of its Subsidiaries to, engage in any transaction or
group of related transactions (including, without limitation, the purchase,
lease, sale or exchange of any Properties, Personal Property or Intellectual
Property of any kind or the rendering of any service) involving an expected
payment by or to the Company or any Subsidiary in excess of $60,000 with any
Affiliate, except (i) compensation and employee benefit matters by the
Compensation Committee of the Board or (ii) any transaction approved by the
Board or any committee of the Board.

     6.4. Availability of Conversion Shares. The Company shall at all times that
any of the Notes or any shares of Series B Preferred Stock are issued and
outstanding reserve and keep available out of its authorized but unissued Common
Stock, for the purpose of effecting the conversion of Notes and the Series B
Preferred Stock, the full number of shares of Common Stock then issuable upon
the conversion of the Notes and the Series B Preferred Stock. The Company will
from time to time in accordance with the Maryland General Corporation Law
increase the authorized amount of Common Stock if at any time the number of
shares of Common Stock remaining unissued and available for issuance shall be
insufficient to permit full conversion of Notes and the Series B Preferred
Stock.

     6.5. Corporate Headquarters. For a period of not less than one year after
the Closing Date, the Company shall not relocate its corporate headquarters
outside of Pittsburgh, Pennsylvania.

     6.6. HSR. If at any time after the date hereof, the Purchaser or any
Related Transferee reasonably determines that the filing of a notification under
the HSR Act is required in connection with the conversion or possible conversion
of all or any portion of the Notes and/or Series B Preferred Stock, then the
Company shall as soon as reasonably practicable reimburse such person for the
costs of filing such notification. The Company agrees to make any filing
required under the HSR Act reasonably promptly after the filing of such person's
notification. Each of the Company and the Purchaser agree to provide the other
with such information as is reasonably required to make such filings.

     SECTION 7.  RESTRICTIVE LEGEND.

representing any (i) shares of Series B Preferred Stock, (ii) Conversion Shares

     (d) by the Purchaser, if (i) the Board of Directors of the Company shall or

in favor of the Stockholder Proposal or withdraw the Board Recommendation, (B)
modify the Board Recommendation in a manner adverse to the Purchaser, or (C)

in the Proxy Statement or failed to hold the Company Meeting, in each case prior
to the Termination Date (including any extensions thereof by exercise of the
Company's options granted in Sections 9.2(c)(i) and (ii)), unless in each case,
the failure to take such action is caused by a temporary restraining order,
preliminary or permanent injunction or other order or decree or regulatory or
legal action or the enactment of any statutes, rules or regulations which
prevent the consummation of the transactions contemplated hereby;

     (e) by either the Purchaser or the Company, if at the Company Meeting

<PAGE>   78

from consummating the transactions contemplated hereby shall have been entered
and become final and nonappealable;

     (g) by either the Purchaser or the Company, if there shall have been a
material breach by the other of any of its representations, warranties,
covenants or agreements contained in this Agreement, which breach would result
in the failure to satisfy one or more of the conditions set forth in Section
1.4(a) (in the case of a breach by either the Company or the Purchaser) or
Section 1.4(b) (in the case of a breach by the Company) or Section 1.4(c) (in

full by the Company in accordance with Section 9.3.

     9.3. Effect of Termination. In the event of the termination of this
Agreement pursuant to Section 9.2, this Agreement, except for the provisions of
the second sentence of Section 5.1, this Section 9.3 and Sections 9.4, and 19,
shall become void and have no effect, without any liability on the part of any
party or any of its affiliates. Notwithstanding the foregoing, nothing in this
Section 9.3 shall relieve any party to this Agreement of liability for any
willful breach of any provision of this Agreement.

     9.4. Payments Upon Termination. (a) Upon a termination of this Agreement

     and the Company pursuant to Section 9.2(a) no Termination Fee or Expenses
     shall be payable, unless otherwise agreed in writing;

          (ii) in the event of a termination of this Agreement by the Purchaser
     pursuant to Section 9.2(d), 9.2(g) or 9.2(h), or pursuant to Section 9.2(e)
     if both (A) any Competing Transaction is publicly proposed or announced on
     or after the date hereof and prior to the Company Meeting being held and
     (B) within 12 months of a termination pursuant to Section 9.2(e) the
     Company enters into a definitive agreement with respect to, or consummates,
     a Competing Transaction, the Termination Fee shall be the amount of
     $2,250,000 plus the amount of the Purchaser's Expenses (as defined below);
     and

          (iii) in the event of a termination of this Agreement pursuant to any

     Company shall pay to the Purchaser the Purchaser's Expenses.

     (b) The parties agree that the "Purchaser's Expenses" shall be the amount
of the Purchaser's reasonable, documented costs and expenses incurred in
connection with this transaction (including, without limitation, the fees and

one Termination Fee or more than one amount in payment of the Purchaser's
Expenses be payable under this Agreement.

     (d) The Company acknowledges that the agreements contained in paragraph (a)
of this Section 9.4 are an integral part of the transactions contemplated by
this Agreement, and that, without these agreements, the Purchaser would not
enter into this Agreement; accordingly, if the Company fails to pay promptly any
Termination Fee or Purchaser's Expenses payable by it pursuant to this Section
9.4, then the Company shall pay

                                      -26-

to the Purchaser its costs and expenses (including attorneys' fees) in
connection with any litigation brought by the Purchaser to obtain payment of
such Termination Fee or Purchaser's Expenses, together with interest on such
amounts at the prime or base rate of The Chase Manhattan Bank from the date such
payment was due under this Agreement until the date of payment.

     (e) The payment of a Termination Fee and/or Purchaser's Expenses hereunder
will constitute the sole and exclusive remedy of the Purchaser prior to the
Closing or the termination of this Agreement in accordance with its terms
regardless of any breach or alleged breach of this Agreement by the Company. In
no event will a Termination Fee or Purchaser's Expenses be payable pursuant to
this Section 9.4 if, prior to the termination of this Agreement, the Purchaser
shall have materially breached any of its representations, warranties, covenants
or agreements contained in this Agreement, which breach would result in a
failure to satisfy one or more of the conditions set forth in Section 1.4(a) or
1.4(c) and such breach shall be incapable of being cured or, if capable of being
cured, shall not have been cured within 20 days after written notice thereof
shall have been received by the Purchaser.

     (f) In the event that the Closing occurs, the Purchaser agrees to instruct
the Escrow Agent in writing to release to the Company as soon as practicable all
funds held by the Escrow Agent pursuant to the Escrow Agreement.

     SECTION 10.  INDEMNIFICATION.

     10.1. Survival of Representations, Warranties, Agreements and Covenants,
etc. All representations and warranties in this Agreement and in the Ancillary
Documents shall survive the execution and delivery of this Agreement and the
Closing for a period of 18 months and shall in no way be affected by any
investigation or knowledge of the subject matter thereof made by or on behalf of
any Purchaser; provided, however, that the representations and warranties set
forth in Sections 2.1 through 2.4, 2.19, 3.1 and 3.2 and 3.6 shall survive
indefinitely. All agreements and covenants contained herein shall survive the
Closing until, by their respective terms, they are no longer operative. The
Closing shall not be deemed in any way to constitute a waiver by any party of
any powers, rights or remedies that it may have with respect to any obligations
of the other parties hereunder, including, without limitation with respect to
any misrepresentation or breach of warranty Known to such party at the time of
Closing. No claim shall be made with respect to any representation, warranty,
covenant or agreement after it ceases to survive except that in the event that
any Purchaser Entity receives notice or identifies a matter which provides a
reasonable basis for indemnification hereunder and provides notice to the
Company within the applicable period provided for in this Section 10.1 of the
receipt of such notice or of the matter so identified and such claim shall not
have been finally resolved before the expiration of the applicable period
referred to in this Section 10.1 any representation, warranty, covenant or
agreement that is the basis for such claim shall continue to survive with
respect to such claim and shall remain a basis for indemnity as to such claim
until such claim is finally resolved.

     10.2. Indemnification by the Company.

     (a) From and after the Closing, the Company shall indemnify, defend and
hold the Purchaser, its Affiliates, their respective officers, directors,
partners, employees, attorneys, agents, representatives, successors and assigns
(each a "Purchaser Entity") harmless from and against all claims, losses
(including, without limitation, losses of earnings), liabilities, obligations,
payments, damages (actual, punitive or consequential), charges, judgments,
fines, penalties, amounts paid in settlement, costs and expenses (including,
without limitation, interest which may be imposed in connection therewith, costs
and expenses of investigation, actions, suits, proceedings, demands, assessments
and fees, expenses and disbursements of counsel, consultants and other experts)
("Losses") incurred or suffered by a Purchaser Entity (whether incurred or
suffered directly or indirectly through ownership of capital stock of the
Company) based upon, arising out of, or in connection with (i) the breach of any
of the representations, warranties or covenants of the Company in this Agreement
or in any Ancillary Document or (ii) claims by third parties relating to the
Agreement or any Ancillary Document or any of the transactions contemplated
hereby or thereby, the use of the proceeds thereof or any related transaction or
claim, litigation, investigation or proceeding relating to any of the foregoing,
regardless of whether the Purchaser Entity is a party thereto. Any
indemnification payment (the "Indemnification Payment") by the Company to a
Purchaser in connection with a (x) breach of the representations, warranties and
covenants of the Company or (y) claims by
                                      -27-
<PAGE>   80

third parties shall include an additional amount such that the Purchaser suffers
no loss as a result of any diminution in the as-converted value of the
Purchaser's equity related to its investment in the Company as a result of such
Indemnification Payment.

     (b) If the Purchaser in its sole discretion determines that any
Indemnification Payment need not be paid in cash, then such Indemnification
Payment shall, at the option of the Purchaser, be effected by decreasing the
Conversion Price (as defined in the Articles Supplementary) of Purchaser's
shares of the Series B Preferred Stock by an amount equal to the Indemnification
Payment divided by the number of Conversion Shares into which such shares of
Series B Preferred Stock are then convertible; provided, however, that Purchaser
shall not have the right to decrease the Conversion Price below $3.00 and any
Indemnification Payment shall be paid in cash to the extent it would result in a
decrease of the Conversion Price below $3.00.

     10.3. Indemnification by the Purchaser. From and after the Closing, the
Purchaser and any Related Transferee shall jointly and severally indemnify,
defend and hold the Company, its Affiliates, their respective officers,
directors, employees, attorneys, agents, representatives, successors and assigns
(each a "Company Entity") harmless against all Losses incurred or suffered by a
Company Entity (whether incurred or suffered directly or indirectly through the
Purchaser's investment in the Company) arising from the breach of any of its
representations, warranties or covenants in this Agreement or in any Ancillary
Documents.

     10.4. Limitations. Notwithstanding anything to the contrary in this
Agreement, no Indemnification Payment by the Company pursuant to this Section 10
with respect to any Losses otherwise payable hereunder pursuant to clause (i) of
Section 10.2 as a result of a breach of the Company's representations,
warranties and covenants (other than any Losses resulting from breaches of the
representation and warranty in Sections 2.1 through 2.4 and 2.19) and no
Indemnification Payment by the Purchaser pursuant to Section 10.3, in each case,
shall be payable until the time as such Losses shall aggregate to more than
$100,000 at which point the Indemnifying Party (as hereinafter defined) shall be
obligated to indemnify the Indemnified Party (as hereinafter defined) from and
against all Losses. In no event shall the Company's obligations in respect of
indemnification exceed the Purchase Price. Except as provided in Section 9, this
Section 10 constitutes the exclusive remedy for the breach of covenants,
agreements, representations or warranties set forth in this Agreement; provided,
however, that the provisions of this Section 10 will not prevent the parties
hereto from seeking specific performance or injunctive relief in connection with
the breach of a covenant or an agreement of any party hereto; provided, further,
that any breach of covenants, agreements, representations or warranties set
forth in this Agreement by either party hereto shall not excuse performance
under the Ancillary Documents or the Joint Venture Partnership Agreement.

     10.5. Procedure.

     (a) A party or parties responsible for indemnifying another party against
any matter pursuant to this Agreement is referred to herein as the "Indemnifying
Party," and a party or parties entitled to indemnity is referred to as the
"Indemnified Party."

     (b) An Indemnified Party under this Agreement shall, with respect to claims
asserted against such party by any third party, give written notice to each
Indemnifying Party of any liability which might give rise to a claim for
indemnity under this Agreement within 60 business days of the receipt of any
written claim from any such third party, and with respect to other matters for
which the Indemnified Party may seek indemnification, give prompt written notice
to each Indemnifying Party of any liability which might give rise to a claim for
indemnity; provided, however, that any failure to give such notice will not
result in a waiver of any rights of the Indemnified Party except to the extent
Indemnifying Party was deprived of its rights to recover any payment under its
applicable insurance coverage or was otherwise materially prejudiced as a result
of such failure by the Indemnified Party.

     (c) As to any claim, action, suit or proceeding by a third party, the
Indemnifying Party shall be entitled to assume the defense, compromise or
settlement of any such matter through the Indemnifying Party's own attorney (who
shall be reasonably satisfactory to the Indemnified Party); provided, however,
that if the Indemnifying Party reasonably determines that an adequate and proper
defense is not being provided by the Indemnified Party or if the Indemnified
Party elects not to assume such defense, then the Indemnifying Party shall
assume such defense.

                                      -28-
<PAGE>   81

The Indemnified Party shall provide such cooperation and such access to its
books, records and properties as the Indemnifying Party shall reasonably request
with respect to such matter; and the parties hereto agree to cooperate with each
other in order to ensure the proper and adequate defense thereof, it being
understood that the Indemnified Party shall control any such defense unless the
Indemnifying Party has assumed such defense in accordance with the terms hereof.

     (d) Neither an Indemnified Party nor an Indemnifying Party shall make any
settlement of any claims without the written consent of the other party, which
consent shall not be unreasonably withheld. Without limiting the generality of
the foregoing, it shall not be deemed unreasonable to withhold consent to a
settlement involving injunctive or other equitable relief against the other
party or its assets, employees or business.

     (e) With regard to claims of third parties for which indemnification is
payable hereunder, such indemnification shall be paid by the Indemnifying Party
upon the earliest to occur of: (i) the entry of a judgment against the
Indemnified Party and the expiration of any applicable appeal period, or if
earlier, five days prior to the date that the judgment creditor has the right to
execute the judgment or if earlier the date that the Indemnified Party must post
any bond with respect to any judgment or other judicial ruling, (ii) the date
payment is due in respect of the entry of an unappealable judgment or final
appellate decision against the Indemnified Party, (iii) the date payment is due
in respect of a settlement of the claim or (iv) with respect to indemnities for
Tax liabilities, upon the issuance of any resolution by a taxation authority.
Notwithstanding the foregoing, expenses of counsel to the Indemnified Party
shall be reimbursed on a current basis by the Indemnifying Party if such
expenses are a liability of the Indemnifying Party. With regard to other claims
for which indemnification is payable hereunder, such indemnification shall be
paid promptly by the Indemnifying Party upon demand by the Indemnified Party.

     SECTION 11.  FURTHER ASSURANCES. At any time or from time to time after the
Closing, the Company, on the one hand, and the Purchaser, on the other hand,
agree to cooperate with each other, and at the request of the other party, to
execute and deliver any further instruments or documents and to take all such
further action as the other party may reasonably request in order to evidence or
effectuate the consummation of the transactions contemplated hereby.

     SECTION 12.  SUCCESSORS AND ASSIGNS. This Agreement shall bind and inure to
the benefit of the Company and the Purchaser and the respective successors,
permitted assigns, heirs and personal representatives of the Company and the
Purchaser except that the Company may not assign its rights and obligations
under this Agreement to any person without the prior written consent of the
Purchaser. The parties hereby agree that, upon a transfer of any interest in
this Agreement to a permitted assign, such transferring party will, at or prior
to such transfer, ensure that such permitted assign becomes a party to the
Investor Agreement. In addition, and whether or not any express assignment has
been made, the provisions of this Agreement which are for the Purchaser's
benefit as a purchaser or holder of the Notes and the Series B Preferred Stock
are also for the benefit of, and enforceable by, any subsequent holder of any of
such Notes or any of the Series B Preferred Stock and/or the Conversion Shares.

     SECTION 13.  ENTIRE AGREEMENT. This Agreement, the side letter between the
Company and the Purchaser attached hereto as Schedule 13 and the irrevocable
undertaking to capitalize the Purchaser attached hereto as Schedule 13, and the
other writings referred to herein or delivered pursuant hereto which form a part
hereof contain the entire agreement among the parties with respect to the
subject matter hereof and thereof and supersede all prior and contemporaneous

         CAPITAL CONTRIBUTIONS; CAPITAL ACCOUNTS; PARTNERSHIP INTERESTS

         4.1 CAPITAL CONTRIBUTIONS; INITIAL CAPITAL CONTRIBUTIONS.

                  (a) Each Partner shall be required to contribute to the
         Partnership in cash, payable from time to time in accordance with
         Section 4.2 hereof, an amount equal to the sum of the amounts of Class
         A Capital Contributions and Class B Capital Contributions listed on
         Exhibit B hereto opposite such Partner's name under the headings,
         "Class A Capital Contribution" and "Class B Capital Contribution". All
         such capital contributions by all of the Partners are hereinafter
         sometimes collectively referred to as "Tier 1 Capital Contributions".
         To the extent that a Partner receives a return of capital in respect of
         any Class A Capital Contribution or Class B Capital Contribution on or
         before the fifth anniversary of the Effective Date, such returned
         capital shall be subject to subsequent capital call with respect to

         that the Partners or their Affiliates shall not be obligated to
         maintain liquid reserves in amounts equal to such returned capital for
         subsequent re-contribution. Nothing herein shall require the
         Partnership to make such subsequent capital call before electing to
         make a capital call for Tier 2 Capital Contributions, as provided in
         Section 4.3 below.

                  (b) On the Effective Date, the Partners shall make initial
         capital contributions to the Partnership, in cash, pro rata in
         proportion to their Tier 1 Capital Contributions obligations, as
         determined by the Managing General Partner and a Majority Interest, but
         not to exceed amounts reasonably necessary for the initial
         capitalization of the Partnership. Such initial capital contributions
         shall be credited against the Partners' respective Tier 1 Capital
         Contributions obligations.

         4.2 TIER 1 CAPITAL CONTRIBUTIONS.

                  (a) The Managing General Partner and a Majority Interest shall
         determine, from time to time, the capital needs of the Partnership.
         Upon such determination, the Managing General Partner shall give
         written notice to each Partner (a "Tier 1 Capital Call Notice"). The
         Partners shall make Tier 1 Capital Contributions to the Partnership,
         pro rata in proportion to their respective Tier 1 Capital Contributions
         obligations. Capital constituting all or a portion of IHC LP's Tier 1
         Capital Contributions shall be allocated as follows: (i) 53.02% as a
         Class A Capital Contribution and (ii) 46.98% as a Class B Capital
         Contribution, consistent with Exhibit B attached hereto. Each Partner
         shall have five (5) days from the date such Tier 1 Capital Call Notice
         is given to contribute to the Partnership its required amount of
         additional capital constituting all or a portion of its respective Tier
         1 Capital Contributions obligations. Each Partner shall receive a
         credit to its Capital Account in the amount of any such capital that it
         contributes to the Partnership.

                  (b) If a Partner does not timely contribute its required
         portion of the Tier 1 Capital Contributions when and in such amounts as
         required pursuant to subsection (a) hereof, that Partner shall be in
         default under this Agreement. The Managing General Partner or those
         non-defaulting Partners that hold a majority of the Percentage
         Interests held by all non-defaulting Partners may exercise any one or
         more of the following remedies, all of which are cumulative, and may be
         exercised concurrently (provided, however, that if more than one remedy
         is exercised, the non-defaulting Partners may not be compensated or
         obtain relief in the aggregate in excess of the actual portion of the
         Tier 1 Capital Contribution that the defaulting Partner has



                                       13

         failed to contribute, together with reimbursement for related expenses
         as and to the extent expressly permitted hereunder):

                           (i) One or more of the non-defaulting Partners may
                  advance funds to the Partnership to cover those amounts which
                  the defaulting Partner fails to contribute. Amounts that a
                  non-defaulting Partner(s) so advances on behalf of the
                  defaulting Partner shall become a fully-recourse loan due and
                  owing from the defaulting Partner to such non-defaulting
                  Partner(s) and shall bear interest at the lesser of the
                  maximum lawful rate and the rate of fifteen percent (15%) per
                  annum, payable monthly. All cash distributions otherwise
                  distributable to the defaulting Partner under this Agreement
                  shall instead be paid to the non-defaulting Partner(s) making
                  such advances until such advances and interest thereon are
                  paid in full. Any such advances shall be due and payable by
                  the defaulting Partner one (1) year from the date that such
                  advance was made, with any amounts repaid applied first to
                  interest and thereafter to principal. Effective upon a
                  Partner's becoming a defaulting Partner, such defaulting
                  Partner grants to the non-defaulting Partner(s) that advances
                  funds under this Section a security interest in such
                  defaulting Partner's right to its allocable share of Profits
                  and Losses, and its distributive share of the assets, of the
                  Partnership, to secure its obligation to repay such advances
                  and agrees to execute and deliver a promissory note evidencing
                  such obligations in form and substance as provided in this
                  clause (i) and reasonably acceptable to the Managing General
                  Partner, together with a security agreement in a form
                  reasonably acceptable to the Managing General Partner and such
                  UCC-1 financing statements and other documents as such
                  non-defaulting Partner(s) may reasonably request. If the
                  defaulting Partner shall fail to make its monthly payments of
                  interest or pay the loan in full when due, the defaulting
                  Partner shall lose, until such time as the default Partner
                  cures the default: (i) its voting and approval rights under
                  the Delaware Act, the Certificate and this Agreement and (ii)
                  its ability, if any, to participate in the management and
                  operations of the Partnership. In addition, the defaulting
                  Partner shall have no right to receive any distributions from
                  the Partnership until the non-defaulting Partners have first
                  received distributions in an amount equal to the additional
                  capital contributed by each non-defaulting Partner to the
                  Partnership (pursuant to the capital call as to which the
                  defaulting Partner defaulted) plus a cumulative,
                  non-compounded return thereon at the lesser of the maximum
                  lawful rate and the rate of fifteen percent (15%) per annum.

                           (ii) The then existing Percentage Interests of the
                  Partners (other than the Executives) shall be proportionately
                  adjusted to reflect the failure of the defaulting Partner to
                  contribute its required capital to the Partnership.

                           (iii) One or more of the non-defaulting Partners that
                  hold a majority of the Percentage Interests held by all
                  non-defaulting Partners may with the consent of the Managing
                  General Partner dissolve the Partnership, in which event the
                  Partnership shall be wound-up, liquidated and terminated
                  pursuant to Article XIII hereof.

                           (iv) The Partnership or one or more of the
                  non-defaulting Partners (other than the Executives) may
                  purchase the defaulting Partner's entire Partnership Interest
                  in accordance with the same terms and conditions as those set
                  forth in Section 11.8 hereof except that the purchase price
                  shall be an amount equal to eighty percent (80%) of the
                  amounts the Selling Partner would have received under Section
                  11.8(a)(iii) hereof based upon a Stated Value determined in
                  good faith; provided, that, the defaulting Partner shall not
                  have the rights of a Receiving Partner under Section
                  11.8(a)(ii) and shall be deemed to have accepted the offer of
                  purchase.

                           (v) One or more of the non-defaulting Partners may
                  contribute the capital that the defaulting Partner failed to
                  so contribute and such defaulting Partner shall have



                                       14

                  no right to receive any distributions from the Partnership
                  until the non-defaulting Partners have first received
                  distributions in an amount equal to the additional capital
                  contributed by each non-defaulting Partner to the Partnership,
                  in addition to any preferred return (and the priority of such
                  return) that may have been earned or payable with respect
                  thereto as if such contribution had been made by the
                  defaulting Partner.

                  (c) Each Partner acknowledges and agrees that (i) a default by
         any Partner in making Tier 1 Capital Contributions will result in the
         Partnership's and the non-defaulting Partners' incurring certain costs
         and other damages in an amount that would be extremely difficult or
         impractical to ascertain, and (ii) the remedies described herein bear a
         reasonable relationship to the damages which the Partners estimate may
         be suffered by the Partnership and the non-defaulting Partners by
         reason of the failure of a defaulting Partner to make any such required
         capital contribution and the exercise of any or all of the above
         described remedies is not unreasonable under the circumstances existing
         as of the date hereof.

                  (d) The exercise by the Managing General Partner or
         non-defaulting Partners, as applicable, of one or more remedies
         provided in this Section shall not be a waiver or limitation of the
         right to pursue any one or more remedies available hereunder or at law
         or equity with respect to any subsequent default.

                  (e) For the period commencing when a Partner does not timely
         contribute its required portion of Tier 1 Capital Contributions until
         such time as such loan is paid in full, any Preferences otherwise
         accruing to the defaulting Partner under this Agreement shall not be
         compounded (but shall accrue as aforesaid).

         4.3 ADDITIONAL CAPITAL CONTRIBUTIONS.

                  This Section relates only to required capital contributions IN
ADDITION TO Tier 1 Capital Contributions. The sole purpose of the Tier 2 Capital
Contributions is to provide the Partnership with additional capital necessary to
operate the Hotels and other, related assets (and any other property) acquired
by the Partnership (using Tier 1 Capital Contributions) and Tier 2 Capital
Contributions are expressly not intended for the acquisition of interests in
Hotels and other, related assets (and any other property). The consent of all
Partners shall be required for the Partnership to make a Tier 2 Capital
Contribution capital call to pay for capital expenditures with respect to a
Hotel and its other, related assets to the extent that such capital expenditure
exceed those required by the licensor or franchisor under such Hotel's license
agreement or franchise agreement. This Section is not intended, and shall not be
construed, as having any effect on the Partnership's use of Tier 1 Capital
Contributions, the Partners' obligations to make Tier 1 Capital Contributions
and the Partnership's and the Partners' remedies with respect to any failure to
make the Tier 1 Capital Contributions. To the extent that a Partner receives a
return of capital in respect of any Tier 2 Capital Contribution on or before the
fifth anniversary of the Effective Date, such returned capital shall be subject
to subsequent capital call, on the terms provided in this Section 4.3, provided,
that the Partners or their Affiliates shall not be obligated to maintain liquid
reserves in amounts equal to such returned capital for subsequent
re-contribution. For the avoidance of doubt, the Executives shall be required to
make Tier 2 Capital Contributions in accordance with the provision of this
Section 4.3.

                  (a) The Partners shall contribute additional capital to the
         Partnership as described in the first paragraph of this Section 4.3, in
         proportion to their respective Percentage Interests ("Tier 2 Capital
         Contributions") and in such amounts and at such times as required by
         the Managing General Partner with the consent of a Majority Interest.
         Upon such determination, the Managing General Partner shall give
         written notice thereof to each Partner (the "Tier 2 Capital Call
         Notice"). Each Partner shall have twenty (20) days from the date the
         Tier 2 Capital Call Notice is given (the "Tier 2 Capital Call Notice
         Period") to contribute its required Tier 2 Capital



                                       15
<PAGE>   105


         Contribution to the Partnership; provided, however, if the stated
         reason for the capital call is to cure a default under any obligation
         of the Partnership, the Tier 2 Capital Call Notice Period may be such
         lesser time as indicated in the Tier 2 Capital Call Notice. Each
         Partner shall receive a credit to its Capital Account in the amount of
         the Tier 2 Capital Contribution that it contributes to the Partnership.

                  (b) If a Partner does not timely contribute additional capital
         when and in such amounts as required pursuant to subsection (a) hereof,
         that Partner shall be in default under this Agreement. In such event,
         the Managing General Partner shall send the defaulting Partner written
         notice of such default, giving the defaulting Partner twenty (20) days
         from the date such notice is given (the "Grace Period") to contribute
         the entire amount of its required Tier 2 Capital Contribution;
         provided, however, that if the stated reason for the capital call is to
         cure a default under any obligation of the Partnership, there shall be
         no Grace Period. If the defaulting Partner does not contribute its
         required Tier 2 Capital Contribution to the Partnership within the Tier
         2 Capital Call Notice Period or within the Grace Period, if applicable,
         the Managing General Partner or those non-defaulting Partners that hold
         a majority of the Percentage Interests held by all non-defaulting
         Partners may exercise any one or more of the following remedies, all of
         which are cumulative, and may be exercised concurrently (provided,
         however, that if more than one remedy is exercised, the non-defaulting
         Partners may not be compensated or obtain relief in the aggregate in
         excess of the actual portion of the Tier 2 Capital Contribution that
         the defaulting Partner has failed to contribute, together with
         reimbursement for related expenses as and to the extent expressly
         permitted hereunder):

                           (i) One or more of the non-defaulting Partners (other
                  than the Executives) may advance funds to the Partnership to
                  cover those amounts which the defaulting Partner fails to
                  contribute. Amounts that a non-defaulting Partner(s) so
                  advances on behalf of the defaulting Partner shall become a
                  loan due and owing from the defaulting Partner to such
                  non-defaulting Partner(s) and shall bear interest at the
                  lesser of the maximum lawful rate and the rate of fifteen
                  percent (15%) per annum, payable monthly. Such loan shall be
                  recourse only to the Partnership Interests of the defaulting
                  Partner. All cash distributions otherwise distributable to the
                  defaulting Partner under this Agreement shall instead be paid
                  to the non-defaulting Partner(s) making such advances until
                  such advances and interest thereon are paid in full. Any such
                  advances shall be due and payable by the defaulting Partner
                  one (1) year from the date that such advance was made, with
                  any amounts repaid applied first to interest and thereafter to
                  principal. Effective upon a Partner's becoming a defaulting
                  Partner, such defaulting Partner grants to the non-defaulting
                  Partner(s) that advance funds under this Section a security
                  interest in such defaulting Partner's right to its allocable
                  share of Profits and Losses, and its distributive share of the
                  assets, of the Partnership, to secure its obligation to repay
                  such advances and agrees to execute and deliver a promissory
                  note evidencing such obligations in form and substance as
                  provided in this clause (i) and reasonably acceptable to the
                  Managing General Partner, together with a security agreement
                  in a form reasonably acceptable to the Managing General
                  Partner and such UCC-1 financing statements and other
                  documents as such non-defaulting Partner(s) may reasonably
                  request. If the defaulting Partner shall fail to make its
                  monthly payments of interest or pay the loan in full when due,
                  the defaulting Partner shall lose, until such time as the
                  default Partner cures the default: (i) its voting and approval
                  rights under the Delaware Act, the Certificate and this
                  Agreement and (ii) its ability, if any, to participate in the
                  management and operations of the Partnership. In addition, the
                  defaulting Partner shall have no right to receive any
                  distributions from the Partnership until the non-defaulting
                  Partner(s) have first received distributions in an amount
                  equal to the additional capital contributed by each
                  non-defaulting Partner(s) to the Partnership (pursuant to the
                  capital call as to which the defaulting Partner defaulted)
                  plus a cumulative, non-compounded



                                       16

                  return thereon at the lesser of the maximum lawful rate and
                  the rate of fifteen percent (15%) per annum.

                           (ii) The then existing Percentage Interests shall be
                  proportionately adjusted to reflect the failure of the
                  defaulting Partner to contribute its required additional
                  capital to the Partnership.

                           (iii) One or more of the non-defaulting Partners
                  (other than the Executives) may contribute the capital that
                  the defaulting Partner failed to so contribute and the
                  defaulting Partner shall have no right to receive any
                  distributions from the Partnership until the non-defaulting
                  Partners have first received distributions in an amount equal
                  to the additional capital contributed by each non-defaulting
                  Partner to the Partnership plus a cumulative, non-compounded
                  return thereon at the lesser of the maximum lawful rate and
                  the rate of fifteen percent (15%) per annum as if such
                  contribution had been made by the defaulting Partner.

                  (c) In addition to any of the remedies set forth in Section
         4.3(b) hereof, if IHC GP or IHC LP defaults on its obligation to make a
         Tier 2 Capital Contribution pursuant to a Tier 2 Capital Call Notice,
         then the Partnership shall have the right to terminate the property
         management agreement(s) covering the Hotel or Hotels for which the
         additional Tier 2 Capital Contribution was required. The defaulting IHC
         GP or IHC LP, and not the Partnership, shall be liable for termination
         payments in connection with such termination and the defaulting IHC GP
         or IHC LP shall indemnify and hold harmless the Partnership and the
         non-IHC Partners against any liability or obligation with respect to
         such payments.

                  (d) Each Partner acknowledges and agrees that (i) a default by
         any Partner in making a required capital contribution will result in
         the Partnership's and the non-defaulting Partners' incurring certain
         costs and other damages in an amount that would be extremely difficult
         or impractical to ascertain, and (ii) the remedies described herein
         bear a reasonable relationship to the damages which the Partners
         estimate may be suffered by the Partnership and the non-defaulting
         Partners by reason of the failure of a defaulting Partner to make any
         required additional capital contribution and the exercise of any or all
         of the above described remedies is not unreasonable under the
         circumstances existing as of the date hereof.

                  (e) The exercise by the Managing General Partner or
         non-defaulting Partners, as applicable, of one or more remedies
         provided in this Section shall not be a waiver or limitation of the
         right to pursue any one or more remedies available hereunder or at law
         or equity with respect to any subsequent default.

                  (f) For the period commencing when a Partner does not timely
         contribute its required portion of the Tier 2 Capital Contributions
         until such time as such loan is paid in full, any Preferences otherwise
         accruing to the defaulting Partner under this Agreement shall not be
         compounded (but shall accrue as aforesaid).

         4.4 CAPITAL ACCOUNTS.

                  (a) Maintenance Rules. The Partnership shall maintain for each
         Partner a separate Capital Account in accordance with this Section 4.4.
         Each Capital Account shall be maintained in accordance with the
         following provisions:

                           (i) Such Capital Account shall be increased by the
                  cash amount or Book Value of any property contributed by such
                  Partner to the Partnership pursuant to this Agreement, such
                  Partner's allocable share of Profits and any items in the
                  nature of income or gains which are specially allocated to
                  such Partner pursuant to Section 5.2 and



                                       17
<PAGE>   107


                  Section 5.3 hereof, and the amount of any Partnership
                  liabilities assumed by such Partner or which are secured by
                  any property distributed to such Partner.

                           (ii) Such Capital Account shall be decreased by the
                  cash amount or Book Value of any property distributed to such
                  Partner pursuant to this Agreement (except as payment with
                  respect to a loan), such Partner's allocable share of Losses
                  and any items in the nature of deductions or losses which are
                  specially allocated to such Partner pursuant to Section 5.2
                  and Section 5.3 hereof, and the amount of any liabilities of
                  the Partner assumed by the Partnership or which are secured by
                  any property contributed by such Partner to the Partnership.

                           (iii) In the event any interest in the Partnership is
                  transferred in accordance with the terms of this Agreement,
                  the transferee shall succeed to the Capital Account of the
                  transferor to the extent that it relates to the transferred
                  interest.

                           (iv) In determining the amount of any liability for
                  purposes of Sections 4.4(a)(i) and (ii) hereof, there shall be
                  taken into account Code Section 752(c) and any other
                  applicable provisions of the Code and Regulations.

                           (v) The Capital Accounts of each Partner shall be
                  adjusted as provided in Regulations Section
                  1.704-1(b)(2)(iv)(j) to take into account any required basis
                  adjustments with respect to Code Section 38 property.

         The foregoing provisions and the other provisions of this Agreement
         relating to the maintenance of Capital Accounts are intended to comply
         with Section 1.704-1(b) of the Regulations and shall be interpreted and
         applied in a manner consistent with such Regulations. If the Managing
         General Partner determines that it is prudent to modify the manner in
         which the Capital Accounts, or any increases or decreases to the
         Capital Accounts, are computed in order to comply with such
         Regulations, the Managing General Partner may authorize such
         modifications, provided that it is not likely to have a material effect
         on the amounts otherwise distributable to any Person.

                  (b) Definition of Profits and Losses. "Profits" and "Losses"
         mean, for each fiscal year or other period, an amount equal to the
         Partnership's taxable income or loss for such year or period,
         determined in accordance with Code Section 703(a) (for this purpose,
         all items of income, gain, loss or deduction required to be stated
         separately pursuant to Code Section 703(a)(1) shall be included in
         taxable income or loss), with the following adjustments:

                           (i) Income of the Partnership that is exempt from
                  federal income tax and not otherwise taken into account in
                  computing Profits and Losses pursuant to this Section 4.4(b)
                  shall be added to such taxable income or loss.

                           (ii) Any expenditures of the Partnership described in
                  Code Section 705(a)(2)(B), or treated as Code Section
                  705(a)(2)(B) expenditures pursuant to Section
                  1.704-1(b)(2)(iv)(i) of the Regulations, and not otherwise
                  taken into account in computing Profits and Losses pursuant to
                  this Section 4.4(b), shall be subtracted from such taxable
                  income or loss.

                           (iii) If the Book Value of any partnership asset is
                  adjusted pursuant to Sections 4.4(c)(ii) through (c)(iv), the
                  amount of such adjustment shall be taken into account as gain
                  or loss from the disposition of such asset for purposes of
                  computing Profits and Losses.



                                       18
<PAGE>   108


                           (iv) Gain or loss resulting from any disposition of
                  property with respect to which gain or loss is recognized for
                  federal income tax purposes shall be computed by reference to
                  the Book Value of the property disposed of, notwithstanding
                  that the adjusted tax basis of such property differs from its
                  Book Value.

                           (v) In lieu of the deduction for depreciation, cost
                  recovery or amortization taken into account in computing such
                  taxable income or loss, there shall be taken into account Book
                  Depreciation as defined in this Section 4.4(b)(v). Except as
                  may otherwise be provided in the Regulations, "Book
                  Depreciation" for any asset means for any fiscal year or other
                  period an amount that bears the same ratio to the Book Value
                  of that asset at the beginning of such fiscal year or other
                  period as the federal income tax depreciation, amortization or
                  other cost recovery deduction allowable for that asset for
                  such year or other period bears to the adjusted tax basis of
                  that asset at the beginning of such year or other period. If
                  the federal income tax depreciation, amortization or other
                  cost recovery deduction allowable for any asset for such year
                  or other period is zero, then Book Depreciation for that asset
                  shall be determined with reference to such beginning Book
                  Value using any reasonable method selected by the Managing
                  General Partner.

                           (vi) Notwithstanding any other provision of this
                  Section 4.4(b), any items that are specially allocated
                  pursuant to Section 5.2 or Section 5.3 shall not be taken into
                  account in computing Profits and Losses.

                  (c) Definition of Book Value. "Book Value" means for any asset
         the asset's adjusted basis for federal income tax purposes, except as
         follows:

                           (i) The initial Book Value of any asset contributed
                  by a Partner to the Partnership shall be the gross fair market
                  value of such asset, as determined by the Managing General
                  Partner in its reasonable discretion.

                           (ii) The Book Values of all Partnership assets shall
                  be adjusted to equal their respective gross fair market
                  values, as determined by the Managing General Partner in its
                  reasonable discretion, as of the following times: (A) on the
                  acquisition of an additional interest in the Partnership by
                  any new or existing Partner in exchange for more than a de
                  minimis capital contribution if the Managing General Partner
                  reasonably determines that such adjustment is necessary or
                  appropriate to reflect the relative economic interests of the
                  Partners in the Partnership; (B) on the distribution by the
                  Partnership to a Partner of more than a de minimis amount of
                  Partnership property as consideration for an interest in the
                  Partnership if the Managing General Partner reasonably
                  determines that such adjustment is necessary or appropriate to
                  reflect the relative economic interests of the Partners in the
                  Partnership; and (C) on the liquidation of the Partnership
                  within the meaning of Section 1.704-1(b)(2)(ii)(g) of the
                  Regulations.

                           (iii) The Book Value of any Partnership asset
                  distributed to any Partner shall be the gross fair market
                  value of such asset on the date of distribution.

                           (iv) The Book Values of Partnership assets shall be
                  increased (or decreased) to reflect any adjustment to the
                  adjusted basis of such assets pursuant to Code Section 734(b)
                  or Code Section 743(b), but only to the extent that such
                  adjustments are taken into account in determining Capital
                  Accounts pursuant to Section 1.704-1(b)(2)(iv)(m) of the
                  Regulations and Section 5.2(d) hereof; provided, however, that
                  Book Values shall not be adjusted pursuant to this Section
                  4.4(c)(iv) to the extent the Managing General Partner
                  determines that an adjustment pursuant to Section 4.4(c)(ii)
                  is necessary or



                                       19
<PAGE>   109


                  appropriate in connection with a transaction that would
                  otherwise result in an adjustment pursuant to this Section
                  4.4(c)(iv).

                           (v) If the Book Value of an asset has been determined
                  or adjusted pursuant to Section 4.4(c)(i), 4.4(c)(ii), or
                  4.4(c)(iv) hereof, such Book Value shall thereafter be
                  adjusted by the Book Depreciation taken into account with
                  respect to such asset for purposes of computing Profits and
                  Losses.

         4.5 NEGATIVE CAPITAL ACCOUNTS.

                  If any Partner has a deficit balance in its Capital Account,
such Partner shall have no obligation to restore such negative balance or to
make any Capital Contribution to the Partnership by reason thereof, and such
negative balance shall not be considered an asset of the Partnership or of any
Partner.

         4.6 INTEREST.

                  No interest shall be paid by the Partnership on Capital
Contributions or on balances in Capital Accounts. Nothing in this Section 4.6 is
intended to limit payments of Class A Preference Amounts and Class B Preference
Amounts to Partners as provided hereunder or on payments or contributions made
by non-defaulting Partners pursuant to Sections 4.2 and 4.3 hereof.

         4.7 NO WITHDRAWAL.

                  No Partner shall be entitled to withdraw any part of its
Capital Contributions or its Capital Account or to receive any distribution from
the Partnership, except as provided in Section 6.1, Section 11.10 and Article
XIII of this Agreement.

         4.8 LOANS FROM PARTNERS.

                  A Partner may advance funds to the Partnership upon the
request of the Partnership with the consent of all of the Partners as to the
terms thereof. Nothing in this Section 4.8 shall require the consent of all of
the Partners to the Partnership's incurring indebtedness or similar obligations,
including, without limitation, under secured and unsecured credit facilities of
every kind or nature, with an Affiliate of a Partner, or otherwise, where such
consent is not required under Section 7.2(a)(vi).


                                    ARTICLE V

                                   ALLOCATIONS

         5.1 ALLOCATIONS OF PROFITS AND LOSSES.

                  Profits, Losses and items thereof of the Partnership for each
Fiscal Year (or other fiscal period) shall be allocated to the Partners in such
manner that:

                  (a) the Adjusted Capital Account balances of all Partners with
         positive Adjusted Capital Account balances (after crediting or debiting
         Capital Accounts for Profits, Losses, items thereof, and allocations to
         Capital Accounts pursuant to all other provisions of this Article V for
         such Fiscal Year or other fiscal period) will correspond as closely as
         possible to the distributions that would result if an amount equal to
         the sum of (X) plus (Y) were distributed in accordance with Section
         13.3(d)(iii) at the end of such Fiscal Year or other fiscal period
         where (X) equals the aggregate of the Adjusted Capital Account balances
         of all Partners with positive Adjusted



                                       20
<PAGE>   110


         Capital Account balances and (Y) equals the aggregate amount that would
         be required to be contributed by the Partners with negative Adjusted
         Capital Account balances (as determined pursuant to Section (b) below
         and without duplication for amounts taken into account under clause
         (ii) of the definition of Adjusted Capital Account). Allocations shall
         be made as if the Executives' respective interests in the Partnership
         were not subject to forfeiture pursuant to Section 11.13 hereof.
         Notwithstanding the foregoing, an Executive shall only be allocated
         Profits that are not attributable to a Capital Event only to the extent
         that such Profits reflect such Executive's entitlement to greater
         current or future distribution of Available Cash; and

                  (b) the Adjusted Capital Account balances of all Partners with
         negative Adjusted Capital Account balances (after crediting or debiting
         Capital Accounts for Profits, Losses, items thereof, and allocations
         pursuant to all other provisions of this Article V for such Fiscal Year
         or other fiscal period) will correspond as closely as possible to the
         manner in which economic responsibility for any such negative balances
         in connection with a liquidation of the Partnership at the end of such
         Fiscal Year or other fiscal period would be borne by the Partners under
         the terms of the Agreement or any collateral agreement.

                  (c) Limitation on Loss Allocations. The Losses allocated
         pursuant to Section 5.1(b) hereof and the next sentence of this Section
         5.1(c) to any Partner for any Fiscal Year shall not exceed the maximum
         amount of Losses that may be allocated to such Partner without causing
         such Partner to have an Adjusted Capital Account Deficit at the end of
         such Fiscal Year. All Losses in excess of the limitation in this
         Section 5.1(c) shall be allocated solely to the other Partners in
         proportion to their respective Percentage Interests. If no other
         Partner may receive an additional allocation of Losses pursuant to the
         preceding sentence of this Section 5.1(c), such additional Losses not
         allocated pursuant to Section 5.1(b) of this Agreement or the preceding
         sentence shall be allocated solely to the Managing General Partner.

         5.2 SPECIAL ALLOCATIONS OF PROFITS AND LOSSES.

                  (a) Minimum Gain Chargeback--Partnership Nonrecourse
         Liabilities. If there is a net decrease in Partnership Minimum Gain
         during any Partnership taxable year, certain items of income and gain
         shall be allocated (on a gross basis) to the Partners in the amounts
         and manner described in Section 1.704-2(f) and (j)(2)(i) and (iii) of
         the Regulations, subject to the exemptions set forth in Section
         1.704-2(f)(2), (3), (4) and (5) of the Regulations. This Section 5.2(a)
         is intended to comply with the minimum gain chargeback requirement (set
         forth in Section 1.704-2(f) of the Regulations) relating to Partnership
         nonrecourse liabilities (as defined in Section 1.704-2(b)(3) of the
         Regulations) and shall be so interpreted.

                  (b) Minimum Gain Chargeback--Partner Nonrecourse Debt. If
         there is a net decrease in Partner Minimum Gain during any Partnership
         taxable year, certain items of income and gain shall be allocated (on a
         gross basis) as quickly as possible to those Partners that had a share
         of the Partner Minimum Gain (determined pursuant to Section
         1.704-2(i)(5) of the Regulations) in the amounts and manner described
         in Section 1.704-2(i)(4), (j)(2)(ii) and (iii) of the Regulations. This
         Section 5.2(b) is intended to comply with the minimum gain chargeback
         requirement (set forth in Section 1.704-2(i)(4) of the Regulations)
         relating to partner nonrecourse debt (as defined in Section
         1.704-2(b)(4) of the Regulations) and shall be so interpreted.

                  (c) Qualified Income Offset. If, after applying Section 5.2(a)
         and Section 5.2(b), any Partner has an Adjusted Capital Account
         Deficit, items of Partnership income and gain shall be specially
         allocated (on a gross basis) to each such Partner in an amount and
         manner sufficient to eliminate the Adjusted Capital Account Deficit of
         such Partner as quickly as possible. This Section 5.2(c) is intended to
         comply with the "qualified income offset" requirement set forth in
         Section 1.704-1(b)(2)(ii)(d) of the Regulations and shall be so
         interpreted.



                                       21
<PAGE>   111


                  (d) Basis Adjustments. To the extent an adjustment to the tax
         basis of any Partnership asset pursuant to Section 734(b) or 743(b) of
         the Code is required, pursuant to Section 1.704-1(b)(2)(iv)(m) of the
         Regulations, to be taken into account in determining Capital Accounts,
         the amount of such adjustment to the Capital Accounts shall be treated
         as an item of gain (if the adjustment increases the basis of the asset)
         or loss (if the adjustment decreases such basis), and such gain or loss
         shall be specially allocated to the Partners in a manner consistent
         with the manner in which their Capital Accounts are required to be
         adjusted pursuant to such Section of the Regulations.

                  (e) Nonrecourse Deductions. Nonrecourse Deductions for any
         Fiscal Year or other fiscal period shall be allocated: (i) first, among
         the Partners up to an amount equal to the sum of the Aggregate Net
         Profit Allocations for all of the Partners in proportion to their
         respective Aggregate Net Profit Allocations, and (ii) thereafter, among
         the Partners in proportion to their Percentage Interests.

                  (f) Partner Nonrecourse Deductions. Partner Nonrecourse
         Deductions shall be allocated pursuant to Section 1.704-2(b)(4) and
         (i)(1) of the Regulations to the Partner who bears the economic risk of
         loss with respect to the deductions.

         5.3 CURATIVE ALLOCATIONS.

                  The allocations set forth in Section 5.1(c) and Section 5.2(a)
through Section 5.2(f) hereof (the "Regulatory Allocations") are intended to
comply with certain requirements of the Regulations. It is the intent of the
Partners that, to the extent possible, all Regulatory Allocations shall be
offset either with other Regulatory Allocations or with special allocations of
other items of Partnership income, gain, loss, or deduction pursuant to this
Section 5.3. Therefore, notwithstanding any other provisions of this Article V
(other than the Regulatory Allocations), the Managing General Partner shall make
such offsetting special allocations of Partnership income, gain, loss, or
deduction in whatever manner it determines appropriate so that, after such
offsetting allocations are made, each Partner's Capital Account balance is, to
the extent possible, equal to the Capital Account balance such Partner would
have had if the Regulatory Allocations were not part of the Agreement and all
Partnership items were allocated pursuant to Section 5.1(a) and (b) hereof. In
exercising its discretion under this Section 5.3, the Managing General Partner
shall take into account future Regulatory Allocations under Sections 5.2(a) and
5.2(b) that, although not yet made, are likely to offset other Regulatory
Allocations previously made under Sections 5.2(e) and 5.2(f).

         5.4 TAX ALLOCATIONS: CODE SECTION 704(C).

                  (a) In accordance with Code Section 704(c) and the Regulations
         thereunder, income, gain, loss and deduction with respect to any
         property contributed to the capital of the Partnership shall, solely
         for tax purposes, be allocated among the Partners so as to take account
         of any variation between the adjusted basis of such property to the
         Partnership for federal income tax purposes and its initial Book Value
         (computed in accordance with Section 4.4(c)(i) hereof).

                  (b) If the Book Value of any Partnership asset is adjusted
         pursuant to Section 4.4(c)(ii) hereof, subsequent allocations of
         income, gain, loss and deduction with respect to such asset shall,
         solely for tax purposes, take account of any variation between the
         adjusted basis of such asset for federal income tax purposes and its
         Book Value in the same manner as under Code Section 704(c) and the
         Regulations thereunder.

                  (c) Any elections or other decisions relating to allocations
         made pursuant to this Section 5.4 shall be made by the Managing General
         Partner in any manner that reasonably



                                       22
<PAGE>   112


         reflects the purpose and intention of the Agreement. Allocations
         pursuant to this Section 5.4 are solely for purposes of federal, state,
         and local taxes and shall not affect or in any way be taken into
         account in computing any Partner's Capital Account, or share of
         Profits, Losses, and other items or distributions pursuant to any
         provision of this Agreement.

         5.5 OTHER ALLOCATION RULES.

                  (a) For purposes of determining the Profits, Losses, or any
         other item allocable to any period, Profits, Losses, and any such other
         item shall be determined on a daily, monthly, or other basis, as
         determined by the Managing General Partner using any permissible method
         under Section 706 of the Code and the Regulations thereunder.

                  (b) For federal income tax purposes, every item of income,
         gain, loss, and deduction shall be allocated among the Partners in
         accordance with the allocations under Sections 5.1, 5.2, 5.3 and 5.4 of
         this Agreement.

                  (c) The Partners are aware of the income tax consequences of
         the allocations made by this Article V and hereby agree to be bound by
         the provisions of this Article V in reporting their shares of
         Partnership income and loss for income tax purposes.

                  (d) It is intended that the allocations in Sections 5.1, 5.2,
         5.3 and 5.4 of this Agreement effect an allocation for federal income
         tax purposes consistent with Section 704 of the Code and comply with
         any limitations or restrictions therein.

                  (e) The Partners agree that their Percentage Interests
         represent their respective interests in Partnership profits for
         purposes of allocating excess nonrecourse liabilities (as defined in
         Section 1.752-3(a)(3) of the Regulations) pursuant to Section
         1.752-3(a)(3) of the Regulations.

         5.6 DEPRECIATION RECAPTURE.

                  Pursuant to Regulations Section 1.1245-1(e), to the extent the
Partnership recognizes gain as a result of sale, exchange or other disposition
of Partnership assets which is taxable as ordinary income under Code Section
1245 or Code Section 1250, such ordinary income shall be allocated among the
Partners in the same proportion as the depreciation giving rise to such ordinary
income was allocable among the Partners. In no event, however, shall any Partner
be allocated to ordinary income hereunder in excess of the amount of gain
allocated to the Partner under this Agreement. Any ordinary income that is not
allocated to a Partner due to the gain limitation described in the previous
sentence shall be allocated among those Partners whose shares of total gain on
the sale, exchange or other disposition of the property exceed their respective
shares of depreciation from those Partnership assets being disposed of, in
proportion to their relative shares of the total allocable gain.


                                   ARTICLE VI

                                  DISTRIBUTIONS

         6.1 DISTRIBUTIONS.

                  (a) The Managing General Partner shall review the
         Partnership's accounts at the end of each calendar quarter to determine
         whether distributions are appropriate. On each Distribution Date
         (commencing with the second Fiscal Year quarter following the Effective
         Date hereof or, in the Managing General Partner's sole discretion, the
         first Fiscal Year quarter



                                       23
<PAGE>   113


         following the Effective Date hereof), the Managing General Partner
         shall make such distributions of, and to the extent of, Available Cash
         calculated as of the end of such Fiscal Year quarter, in accordance
         with Section 6.1(b) hereof.

                  (b) The distributions under this Section 6.1 are subject,
         first, to any and all of the Partnership's obligations to lenders,
         indebtedness or other obligations, including, without limitation, under
         secured or unsecured credit facilities of every kind and nature (which
         may include, among other things, additional interest obligations, exit
         fees, equity kickers and similar obligations or payments) and, second,
         to the applicability of Sections 4.2(b), 4.2(c), 4.3(b), 4.3(c), 13.3
         or 13.4. Subject to the immediately preceding sentence, distributions
         of Available Cash shall be made to the Partners in the manner set forth
         below:

                           (i) With respect to Available Cash that does not
                  constitute net proceeds from a Capital Event:

                                    (A) First, to Partners entitled to receive
                           Class B Preference Amounts, any Undistributed Class B
                           Preference Amounts, pro rata in proportion to their
                           respective Undistributed Class B Preference Amounts;

                                    (B) Second, to Partners entitled to receive
                           Class A Preference Amounts, any Undistributed Class A
                           Preference Amounts, pro rata in proportion to their
                           respective Undistributed Class A Preference Amounts;
                           and

                                    (C) Third, to Partners pro rata in
                           proportion to their respective Percentage Interests;

                           (ii) With respect to Available Cash constituting net
                  proceeds from a Capital Event:

                                    (A) First, to Partners entitled to receive
                           Class B Preference Amounts, any Undistributed Class B
                           Preference Amounts, pro rata in proportion to their
                           respective Undistributed Class B Preference Amounts;

                                    (B) Second, to Partners entitled to receive
                           Class A Preference Amounts, any Undistributed Class A
                           Preference Amounts, pro rata in proportion to their
                           respective Undistributed Class A Preference Amounts;

                                    (C) Third, (1) first, to Partners to the
                           extent of their respective Undistributed Class B
                           Capital, pro rata in proportion to the Undistributed
                           Class B Capital, if any, of all Partners, until such
                           Undistributed Class B Capital is reduced to zero, (2)
                           second, to Partners (other than the Executives) to
                           the extent of their respective Undistributed Class A
                           Capital, pro rata in proportion to the Undistributed
                           Class A Capital, if any, of all Partners (other than
                           the Executives), until such Undistributed Class A
                           Capital is reduced to zero, and (3) third, to the
                           Executives, to the extent of their respective
                           Undistributed Class A Capital, pro rata in proportion
                           to the Undistributed Class A Capital, if any, of all
                           Executives, until such Undistributed Class A Capital
                           is reduced to zero; provided, that, (x) the amount
                           available to Partners under clause (1) hereof shall
                           be equal to the lesser of (I) the amount available
                           for distribution to Partners under this subsection
                           (C) and (II) Undistributed Class B Capital as of the
                           date of the distribution (but before giving effect to
                           a such distribution) invested in the Partnership's
                           asset that is the subject of the Capital Event for
                           which the proceeds are being distributed, and (y) the
                           amount available to Partners under clauses (2)



                                       24
<PAGE>   114


                           and (3) hereof shall be the difference between the
                           amount available for distribution under this
                           subsection (C) and the amounts paid to Partners under
                           clause (1) hereof, but such amount shall not be less
                           than zero;

                                    (D) Fourth, to the Partners, to the extent
                           of their respective Undistributed Tier 2 Capital, pro
                           rata in proportion to their respective Undistributed
                           Tier 2 Capital until the Undistributed Tier 2 Capital
                           is reduced to zero; and

                                    (E) Fifth, to the Partners, pro rata in
                           proportion to their respective Percentage Interests.

                           (iii) Any incentive-based management fees payable
                  under property management agreements as described in Section
                  7.16 of this Agreement (i) shall be calculated based upon
                  Available Cash prior to any distributions pursuant to Section
                  6.1(b) and (ii) shall be paid in the first Fiscal Year quarter
                  of the following Fiscal Year (or such later date as the
                  financial statements are available for the prior Fiscal Year
                  pursuant to Article IX hereof) after any distributions
                  pursuant to Sections 6.1(b)(i)(A) and (B), or Sections
                  6.1(b)(ii)(A) and (B), as applicable, and prior to any
                  distributions pursuant to Sections 6.1(b)(i)(C), or Sections
                  6.1(b)(ii)(C), (D) or (E), as applicable; provided, however,
                  that upon a Capital Event which results in the termination of
                  a property management agreement described in Section 7.16 of
                  this Agreement, any outstanding incentive-based management
                  fees under such terminated property management agreement shall
                  be payable upon distribution of proceeds of such Capital Event
                  pursuant to Section 6.1(b)(ii) hereof.

                  (c) Class A Preference Amounts and Class B Preference Amounts
         are, by their terms, calculated on a Fiscal Year basis. Accordingly,
         Fiscal Year quarter distributions in any Fiscal Year shall be made
         based upon the Managing General Partner's reasonable calculation of
         such Preference Amounts on a quarterly basis. In the first Fiscal Year
         quarter of the following Fiscal Year (or such later date as the
         financial statements are available for the prior Fiscal Year pursuant
         to Article IX hereof) distributions for such prior Fiscal Year shall be
         adjusted as necessary in order for the Partners to receive their
         respective Preference Amounts in accordance with the terms hereof.

         6.2 PAYMENTS NOT DEEMED DISTRIBUTIONS.

                  Any amounts paid pursuant to Section 7.4, Section 7.11 or
Section 7.16(a) of this Agreement shall not be considered distributions for
purposes of this Agreement and shall be treated as deductible items for tax
purposes and for purposes of determining Profit or Loss of the Partnership.

         6.3 WITHHELD AMOUNTS.

                  (a) Notwithstanding any other provision of this Article VI to
         the contrary, each Partner hereby authorizes the Partnership to
         withhold and to pay over, or otherwise pay, any withholding or other
         taxes payable by the Partnership with respect to such Partner as a
         result of such Partner's participation in the Partnership. If and to
         the extent that the Partnership shall be required to withhold or pay
         any such taxes, such Partner shall be deemed for all purposes of this
         Agreement to have received a payment from the Partnership as of the
         time such withholding or tax is paid, which payment shall be deemed to
         be a distribution with respect to such Partner's Partnership Interest
         to the extent that the Partner (or any successor to such Partner's
         Partnership Interest) is then entitled to receive a distribution.



                                       25
<PAGE>   115


                  (b) To the extent that the aggregate of such payments to a
         Partner for any period exceeds the distributions to which such Partner
         is entitled for such period, the amount of such excess shall be
         considered a loan from the Partnership to such Partner. Such loan shall
         bear interest (which interest shall be treated as an item of income to
         the Partnership) at the lesser of the maximum rate permitted by law or
         the rate of interest per annum most recently established by Citibank,
         N.A., in New York, New York, as such bank's general reference rate of
         interest (which rate may or may not be the lowest rate of interest then
         charged by such bank), as determined hereunder from time to time, until
         discharged by such Partner by repayment, which may be made in the sole
         discretion of the Managing General Partner out of distributions to
         which such Partner would otherwise be subsequently entitled.

                  (c) Any withholdings authorized by this Section 6.3 shall be
         made at the maximum applicable statutory rate under the applicable tax
         law unless the Managing General Partner shall have received an opinion
         of counsel or other evidence satisfactory to the Managing General
         Partner to the effect that a lower rate is applicable, or that no
         withholding is applicable.


                                   ARTICLE VII

                          MANAGEMENT OF THE PARTNERSHIP

         7.1 DESIGNATION AND AUTHORITY OF MANAGING GENERAL PARTNER AND GENERAL
             PARTNER.

                  (a) The Partners hereby designate CGLH GP as the managing
         general partner of the Partnership. The Partners hereby designate IHC
         GP as the general partner of the Partnership.

                  (b) The overall management and control of the business and
         affairs of the Partnership shall be vested in the Managing General
         Partner and the Managing General Partner shall have all of the power
         and authority of a general partner of the Partnership granted under the
         Act and pursuant to this Agreement. Except as otherwise provided in
         this Agreement and subject specifically to Section 7.2, all decisions
         concerning the management of the business and affairs of the
         Partnership and its assets shall be made exclusively by the Managing
         General Partner, in accordance with the objectives and purposes of the
         Partnership set forth in Section 3.1 hereof. The Managing General
         Partner shall be authorized to execute documents and take actions on
         behalf of the Partnership, in accordance with its power and authority
         granted under the Delaware Act and pursuant to this Agreement, which
         shall be binding on the Partnership and on which third parties shall be
         entitled to rely. The General Partner shall not take part in the
         control (within the meaning of the Delaware Act) of the Partnership's
         business, transact any business in the Partnership's name, or have the
         power to sign documents for or otherwise bind the Partnership other
         than as expressly set forth in this Agreement or as directed by the
         Managing General Partner in writing, and the General Partner shall have
         only the power and authority expressly granted it pursuant to this
         Agreement or by the Managing General Partner in writing. Without
         limiting the foregoing, the General Partner hereby disclaims any power
         or authority that may be granted to a general partner of a partnership
         pursuant to the Delaware Act that is not also granted to the General
         Partner under this Agreement or by the Managing General Partner in
         writing. Any grant of power or authority to the General Partner
         pursuant to this Agreement or by the Managing General Partner is
         non-exclusive and shall not divest the Managing General Partner of any
         such power or authority. Each of the Managing General Partner and the
         General Partner shall amend or otherwise modify its organizational and
         charter documents or take such other action to satisfy or comply with
         bankruptcy-remote, special purpose entity requirements of lenders, or
         other entities extending credit, to the Partnership or its Controlled
         or Non-Controlled Entities. The Partners agree that this Agreement and
         the Certificate may be amended or otherwise modified or such other
         action taken, as necessary to satisfy or otherwise comply with



                                       26
<PAGE>   116


         bankruptcy-remote, special purpose entity requirements of lenders, or
         other entities extending credit, to the Partnership or its Controlled
         or Non-Controlled Entities.

                  (c) Without in any way limiting the provisions of Section
         7.1(b), the General Partner shall submit for approval by the Managing
         General Partner: (i) a proposed business plan within 60 days of the
         effective date of this Agreement for the current Fiscal Year; and (ii)
         thereafter, on or before November 1 of each year that this Agreement
         shall be in effect, a proposed business plan for the next succeeding
         Fiscal Year. If the General Partner shall fail timely to submit any
         such proposed business plan when due, the Managing General Partner may
         submit a business plan for the applicable Fiscal Year, and any costs
         incurred by the Managing General Partner in connection therewith shall
         be deducted from distributions to the General Partner under Section 6.1
         hereof. Simultaneously with the submission of a proposed business plan
         to the Managing General Partner, the General Partner shall distribute
         copies of the proposed business plan (marked "proposed") to the other
         Partners for informational purposes. Each such business plan shall
         contain a proposed operating budget and a proposed capital budget for
         the Hotels and other, related assets, or interests in Hotels and other,
         related assets, presently owned and managed by the Partnership, a
         strategic plan for new acquisitions of Hotels and other, related
         assets, or interests in Hotels and other, related assets, and potential
         funding sources therefor. Each such business plan shall specify
         material assumptions contained therein. Each shall be sufficiently
         detailed so as to allow for the reasonable review thereof. The General
         Partner shall not be deemed to have made any guarantee, warranty or
         representation whatsoever, other than that the General Partner used
         good faith efforts in preparing such proposed plans and diligently
         reviewed and assessed the information provided by Hotel managers, in
         connection with such plans since the Partners acknowledge that such
         plans are intended to set forth reasonable performance objectives and
         goals based upon facts and circumstances known by the General Partner
         at the time of such plans' preparation. If an annual business plan is
         not approved prior to December 31 of the immediately preceding Fiscal
         Year, the Partnership shall be managed and operated in accordance with
         the approved annual business plan for such immediately preceding Fiscal
         Year with each expense item increased (but not decreased) by the
         average Consumer Price Index for all Urban Consumers for the
         immediately preceding calendar year as reported by the U.S. Department
         of Labor Bureau of Labor Statistics ("CPI") and each revenue item
         increased (but not decreased) by Market Tract RevPAR growth percentage
         for the immediately previous 12-month period, as published by Smith
         Travel Research, but in no event less than CPI.

         7.2 MAJOR DECISIONS.

                  (a) All Major Decisions with respect to the Partnership's
         business shall require the prior written approval of all the Partners
         other than the Executives. The term "Major Decision," as used in this
         Agreement, means any decision with respect to the following matters at
         any time:

                  (i) to do any act which would make it impossible to carry on
         the ordinary business of the Partnership;

                  (ii) to possess Partnership property for other than a
         Partnership purpose or assign any rights in specific Partnership
         property for other than a Partnership purpose;

                  (iii) to change or reorganize the Partnership into any other
         legal form or materially change the purpose of the Partnership set
         forth in Section 3.1 hereof;

                  (iv) to require any Limited Partner to make any contribution
         to the capital of the Partnership not provided for hereunder (it being
         understood that additional capital contributions (including, without
         limitation, those described in Sections 4.2 and 4.3 hereof) are
         expressly provided for hereunder);



                                       27
<PAGE>   117


                  (v) except as otherwise permitted herein, to admit any Person
         as a partner of the Partnership or transfer the obligation to make
         Class B Capital Contributions or the right to receive Class B
         Preference Amounts and Undistributed Class B Preference Amounts;

                  (vi) to permit the Partnership to incur any indebtedness,
         direct or indirect, absolute or contingent; provided, however, the
         Partners agree that: (A) the incurrence by the Partnership of any
         single indebtedness to any lender (an affiliate of a Partner or
         otherwise), on market terms, and secured by an interest in property of
         the Partnership, with a loan to value ratio of not greater than
         0.85:1.00 shall not be a Major Decision, if the Partnership exercises
         commercially reasonable efforts to seek such indebtedness from more
         than one unaffiliated institution regularly engaged in the business of
         making loans secured by interests in real property; and (B) the
         incurrence by the Partnership of unsecured debt shall not be a Major
         Decision; or

                  (vii) to approve any acquisition by the Partnership of a Hotel
         or a direct or indirect interest in a Hotel.

         7.3 CERTIFICATE OF LIMITED PARTNERSHIP.

                  The Managing General Partner shall cause the Certificate to be
filed with the Secretary of State of Delaware as required by the Delaware Act
and shall cause to be filed such other certificates or documents (including,
without limitation, copies, amendments, or restatements of this Agreement) as
may be determined by the Managing General Partner to be reasonable and necessary
or appropriate for the formation, qualification, or registration and operation
of a limited partnership (or a partnership in which Limited Partners have
limited liability) in the State of Delaware and in any other state where the
Partnership may elect to do business.

         7.4 COMPENSATION AND REIMBURSEMENT OF MANAGING GENERAL PARTNER AND
             GENERAL PARTNER.

                  Neither the Managing General Partner nor the General Partner
shall be compensated for services rendered to the Partnership as managing
general partner or as general partner, as applicable, unless such compensation
has previously been approved by all of the Partners. The Managing General
Partner shall, however, be reimbursed by the Partnership for all reasonable
expenditures incurred by the Managing General Partner on the Partnership's
behalf. The General Partner shall be reimbursed by the Partnership for all
reasonable expenditures incurred by the General Partner on the Partnership's
behalf that have been approved in advance by the Managing General Partner.

         7.5 PARTNERSHIP FUNDS.

                  Subject to the terms and provisions of the management
agreements entered into by the Partnership for the management of the Hotels and
other, related assets, the funds of the Partnership shall be deposited in such
interest-bearing Partnership account or Partnership accounts as are designated
by the Managing General Partner. All withdrawals from or charges against such
accounts shall be made by the Managing General Partner or by its representative.
Funds of the Partnership may be invested as determined by the Managing General
Partner in accordance with the terms and provisions of this Agreement.

         7.6 RETURN OF CAPITAL.

                  Neither the Managing General Partner nor the General Partner
shall be entitled to the withdrawal or return of its Capital Contribution except
to the extent, if any, that distributions made



                                       28
<PAGE>   118


pursuant to this Agreement or upon termination of the Partnership may be
considered as such by law, and then only to the extent provided for in this
Agreement.

         7.7 DUTIES.

                  The Managing General Partner shall manage the Partnership and
its business and affairs in accordance with the terms of this Agreement to the
best of its ability, and shall use its good faith efforts to carry out the
business of the Partnership in the best interest of the Partnership. The
Managing General Partner shall devote itself to the business of the Partnership
to the extent that it determines is necessary for the efficient discharge of its
obligations hereunder. To the extent that the General Partner acts for and on
behalf of the partnership as expressly granted herein or by the Manager General
Partner, the General Partner shall act to the best of its ability, and shall use
its good faith efforts to carry out the business of the Partnership in the best
interest of the Partnership. The General Partner shall devote itself to its
duties to the extent that the General Partner determines is necessary for the
efficient discharge of its duties.

         7.8 TRANSACTIONS WITH AFFILIATES.

                  Subject to the provisions of Section 7.2 hereof, the terms to
the Partnership of any transaction, agreement or contract involving the
Partnership with any Affiliate of a Partner shall be competitive with the terms
of similar transactions, agreements or contracts obtained by persons in the same
business as the Partnership in arms-length agreements with unrelated parties.

         7.9 OUTSIDE ACTIVITIES.

                  The provisions regarding outside activities of the Managing
General Partner and the General Partner are set forth in Section 8.3 of this
Agreement.

         7.10 RESOLUTION OF CONFLICTS OF INTEREST.

                  Unless otherwise expressly provided in this Agreement or any
other agreement contemplated herein, whenever a conflict of interest exists or
arises between the General Partner, or any of its Affiliates, or the Managing
General Partner, or any of its Affiliates, on the one hand, and the Partnership
or any Limited Partner, on the other hand, any action taken by the Managing
General Partner or the General Partner, as the case may be, in the absence of
bad faith by such entity, and in the case of the General Partner, pursuant to an
express grant of authority under this Agreement or by the Managing General
Partner in writing, shall not constitute a breach of this Agreement or any other
agreement contemplated herein or a breach of any standard of care or duty
imposed herein or therein or under the Delaware Act or any other applicable law,
rule, or regulation unless such action would have constituted a breach of the
Agreement in the absence of such conflict of interest.

         7.11 INDEMNIFICATION.

                  (a) The Partnership shall indemnify and hold harmless the
         Managing General Partner and General Partner and any director, officer,
         employee, agent, or representative of the Managing General Partner or
         the General Partner, against all liabilities, losses, and damages
         incurred by any of them by reason of any act performed or omitted to be
         performed in the name of or on behalf of the Partnership, or in
         connection with the Partnership's business, including attorneys' fees
         and any amounts expended in the settlement of any claims or
         liabilities, losses, or damages, to the fullest extent permitted by the
         Delaware Act, provided, that in the case of the General Partner, the
         General Partner has not exceeded its power and authority granted under
         this Agreement or by the Managing General Partner in writing. The
         negative disposition of any action, suit or proceeding by judgment,
         order, settlement, conviction or upon a plea of nolo

         contendere, or its equivalent, shall not, of itself, create a
         presumption that the indemnified Person has engaged in gross
         negligence, fraud, willful misconduct, or a material breach of this
         Agreement.

                  (b) The Partnership shall indemnify and hold harmless the
         Limited Partners, employee, agent, or representative of the
         Partnership, any Person who is or was serving at the request of the
         Partnership or the Managing General Partner as a director, officer,
         partner, trustee, employee, agent, or representative of another
         corporation, partnership, joint venture, trust, or other enterprise, to
         the fullest extent permitted by the Delaware Act. The negative
         disposition of any action, suit or proceeding by judgment, order,
         settlement, conviction or upon a plea of nolo contendere, or its
         equivalent, shall not, of itself, create a presumption that the
         indemnified Person has engaged in gross negligence, fraud, willful
         misconduct, or a material breach of this Agreement.

                  (c) Notwithstanding anything to the contrary contained in this
         Section 7.11, an indemnified Person shall not be entitled to
         indemnification under Section 7.11 with respect to any claim, issue or
         matter in which it has engaged in gross negligence, fraud, willful
         misconduct, or a material breach of this Agreement.

                  (d) Notwithstanding any of the provisions to this Section 7.11
         to the contrary, no amount shall be paid to any indemnitee under this
         Section 7.11 until the obligations of the Partnership with respect to
         any indebtedness of the Partnership are paid or satisfied in full.
         However, if such indemnitee would otherwise be entitled to be paid
         pursuant to this Section 7.11 but for the preceding sentence, an amount
         of cash equal to the amount which would otherwise be paid to such
         indemnitee shall be held by the Partnership in an escrow account until
         such amounts may be paid to such indemnitee pursuant to this Section
         7.11 or as otherwise required to be paid to satisfy claims against the
         Partnership if there are no other available Partnership assets to pay
         such claims.

         7.12 LIABILITY OF MANAGING GENERAL PARTNER AND THE GENERAL PARTNER.

                  The Managing General Partner may exercise any of the powers
granted to it by this Agreement and perform any of the duties imposed upon it
under the Delaware Act and/or hereunder either directly or by or through its
directors, officers, employees, agents, or representatives. The General Partner
may exercise any of the powers expressly granted to it, and perform any of the
duties expressly imposed upon it, under this Agreement or by the Managing
General Partner in writing either directly or by or through its directors,
officers, employees, agents, or representatives. Neither the Managing General
Partner nor its directors, officers, employees, agents, or representatives shall
be liable to the Partnership or the Limited Partners for errors in judgment or
for any acts or omissions that do not constitute gross negligence, fraud, or
willful or wanton misconduct. Neither the General Partner nor its directors,
officers, employees, agents, or representatives shall be liable to the
Partnership or the Limited Partners for errors in judgment or for any acts or
omissions with respect to matters within its power and authority expressly
granted under this Agreement or by the Managing General Partner in writing, that
do not constitute gross negligence, fraud, or willful or wanton misconduct.

         7.13 RELIANCE BY MANAGING GENERAL PARTNER AND THE GENERAL PARTNER.

                  (a) Each of the General Partner and the Managing General
         Partner may rely and shall be protected in acting or refraining from
         acting upon any resolution, certificate, statement, instrument,
         opinion, report, notice, request, consent, order, bond, debenture, or
         other paper or document believed by it to be genuine and to have been
         signed or presented by the proper party or parties.

                  (b) Each of the Managing General Partner and the General
         Partner may consult with legal counsel, accountants, appraisers,
         management consultants, investment bankers, and other consultants and
         advisers selected by it, and any opinion of any such Person as to
         matters which the Managing General Partner or the General Partner, as
         the case may be, believes to be within such Person's professional or
         expert competence shall be full and complete authorization and
         protection in respect of any action taken or suffered or omitted by the
         Managing General Partner or the General Partner, as the case may be,
         hereunder in good faith and in accordance with such opinion.

         7.14 INSURANCE.

                  The General Partner, on behalf of the Partnership and at the
Partnership's cost and expense, shall, during the entire term hereof, obtain,
maintain and keep in full force and effect, such insurance coverage as the
Managing General Partner reasonably deems advisable.

         7.15 ACQUISITION OF REAL PROPERTY; INVESTMENT BANKING; FINANCING.

                  (a) The Partnership intends to acquire, directly or through
         Controlled Entities and non-Controlled Entities, Hotels and other,
         related assets or interests in Hotels and other, related assets with an
         aggregate Value of $300,000,000.00. The Partnership shall not fail in
         its purposes if the aggregate Value of such Hotels and other, related
         assets or interests in Hotels and other, related assets is less than,
         greater than or equal to, $300,000,000.00, and the power and authority
         of the Partnership and the Managing General Partner hereunder shall in
         no way be diminished or otherwise affected thereby.

                  (b) Notwithstanding any provision in this Agreement to the
         contrary, the Managing General Partner is hereby authorized, on behalf
         of the Partnership and at the Partnership's cost and expense, to enter
         into negotiations for acquisitions of Hotels and other, related assets
         and interests in Hotels and other, related assets, investigate
         potential funding sources for such acquisitions and retain an
         investment bank or similar financial institution (a "Financial
         Institution") to provide investment banking, advisory, underwriting or
         other services in connection with the acquisition or disposition of
         Hotels and/or other, related assets and interests in Hotels and other,
         related assets, and any public offering of securities of the
         Partnership or its Controlled Entities (and non-Controlled Entities) or
         any secondary offering of securities of the Partnership or its
         Controlled Entities (and non-Controlled Entities) (collectively, the
         "Investment Banking Services"). The Managing General Partner, in its
         discretion, may direct the General Partner to enter into negotiations
         for the acquisitions of Hotels and other, related assets and to
         investigate potential funding sources for such acquisitions. For the
         purposes of Section 7.2, the right to negotiate pursuant to this
         Section shall not be deemed an implied consent to the consummation of
         any proposed transaction that may be the subject of such negotiation.

                  (c) If the Partnership seeks to retain a Financial Institution
         other than Lehman Brothers Holdings Inc., or any of its affiliates or
         its subsidiaries (collectively, "Lehman Brothers"), the Partnership
         shall deliver written notice of such intended retention of another
         Financial Institution (the "Notice") to a Senior Vice President of the
         Principal Transactions Group of Lehman Brothers, setting forth the
         identity of such other Financial Institution, the nature of the
         engagement or Investment Banking Services sought and offered, a
         description (including timing) of the contemplated transaction(s), and
         the fees charged by, or payable to, such Financial Institution. For a
         period of fifteen days after the date that Lehman Brothers shall have
         received such notice, Lehman Brothers shall have the right to advise
         the Partnership that Lehman Brothers will perform such Investment
         Banking Services on the terms set forth in the Notice; provided,
         however, that if the fees to be paid such Financial Institution are
         less than the market rate fees charged for the contemplated
         transaction, the fees payable to Lehman Brothers



                                       31
<PAGE>   121


         shall be the market rate fees. The Partners agree, for the purposes of
         this Agreement, that listed on Exhibit C annexed hereto and made a part
         hereof are market rate fees for the types of transactions described
         thereon. If Lehman Brothers declines the engagement set forth in the
         Notice, the Partnership may engage (i) the Financial Institution set
         forth in the Notice on the terms set forth therein or (ii) such other
         Financial Institution to provide the Investment Banking Services set
         forth in the Notice in connection with the contemplated transaction(s)
         described therein for fees not in excess of market rate fees. Lehman
         Brothers shall be a third party beneficiary of this Section and shall
         have the right to enforce the terms of this Section to their fullest
         extent.

                  (d) For so long as CGLH GP is the Managing General Partner,
         CGLH GP shall use its good faith efforts to obtain, on behalf of the
         Partnership, equity and/or debt financing for the acquisition of Hotels
         and other, related assets, on market terms.

         7.16 MANAGEMENT OF THE REAL PROPERTY.

                  (a) The Corporation shall have the option to manage, or have
         one or more of its Affiliates manage, the Hotels and other, related
         assets owned by the Partnership or its Controlled Entities pursuant to
         one or more property management agreements, which management agreements
         shall be substantially in the form annexed hereto as Exhibit D (the
         Corporation, or one or more Affiliates in its capacity as manager, the
         "Manager"). The Partners agree that the terms of such form property
         management agreement are subject to modification in connection with the
         specific requirements and financial performance of a particular Hotel
         and its other, related assets, which modifications shall be agreed upon
         before the acquisition of such Hotel and its other, related assets. For
         the management of a Hotel and its other, related assets, Manager shall
         be entitled to receive an annual base management fee and an incentive
         based management fee, on terms and conditions provided in the property
         management agreement covering such Hotel and other, related assets. In
         addition to any other terms and conditions set forth in any such
         management agreement, any incentive based management fee shall be
         payable only after the Partners have been paid their respective Class A
         Preference Amounts and Class B Preference Amounts in accordance with
         Section 6.1(b) hereof. Each property management agreement shall provide
         that the Manager shall not have the right to receive termination
         payments or fees for the termination of a property management agreement
         upon the sale, transfer or other disposition of the subject Hotel (and
         its other, related assets) if the original acquisition of such Hotel
         (and its other, related assets) was identified by the Partnership, a
         Controlled Entity or a non-Controlled Entity, prior to the acquisition
         thereof as a short-term acquisition. In addition, each property
         management agreement shall provide that the payment of termination
         payments or fees, if any, for the termination of a property management
         agreement upon the sale, transfer or other disposition of the subject
         Hotel (and its other, related assets) may be deferred (without
         interest, premium or penalty) for one year from the termination of such
         property management agreement and, no termination payments or fees
         shall be due under the terminated property management agreement if, at
         or before the end of such one-year period, the Partnership, a
         Controlled Entity or a non-Controlled Entity enters into another
         property management agreement, in substantially the same form of
         property management agreement as the agreement being terminated, with
         such Manager or such Manager's Affiliate covering a Hotel (and its
         other, related assets), and the ratio of management fees payable under
         such other property management agreement to the Class B Capital
         Contributions invested in such Hotel (and its other, related assets) is
         equal to or greater than such ratio with respect to the terminated
         property management agreement and the related Hotel (and other, related
         assets). In addition, each property management agreement with a Manager
         shall provide that, upon the occurrence of an event described in
         Section 4.3(c), the Manager shall look to the defaulting IHC Partner
         for payment of the applicable termination payments or fees, if any.
         Nothing set forth in this Section 7.16 shall affect the rights of IHC
         GP and IHC LP under Section 7.2 of this Agreement.

                  (b) For so long as CGLH LP, or its affiliate, shall remain a
         partner of the Partnership, the Partnership shall retain CG Asset
         Management Company LLC as the asset manager of the Hotels and other,
         related assets pursuant to an Asset Management Agreement substantially
         in the form annexed hereto as Exhibit E.

                   RIGHTS AND OBLIGATIONS OF LIMITED PARTNERS

         8.1 LIMITATION OF LIABILITY.

                  The Limited Partner shall have no liability under this
Agreement except as provided herein or under the Delaware Act.

         8.2 MANAGEMENT OF BUSINESS.

                  The Limited Partner shall not take part in the control (within
the meaning of the Delaware Act) of the Partnership's business, transact any
business in the Partnership's name, or have the power to sign documents for or
otherwise bind the Partnership other than as specifically set forth in this
Agreement. Notwithstanding anything stated or implied to the contrary in this
Agreement, neither of the Executives shall have any voting, consent or approval
rights as a limited partner of this Partnership or otherwise under this
Agreement, the Delaware Act or otherwise, and each of the Executives hereby
disclaims any such rights to the fullest extent permitted by law. If an
Executive shall nevertheless have voting, consent or approval rights with
respect to Partnership affairs under this Agreement, the Delaware Act or
otherwise, such Executive shall, in consideration of the rights and interests
granted hereunder, be deemed to have irrevocably appointed the Managing General
Partner, as his true and lawful proxy and attorney-in-fact, with full power of
substitution and re-substitution, to exercise any and all such rights, effective
for the term of the Partnership (including any extensions thereof and the term
of any wind-up following dissolution). Nothing herein shall preclude an
Executive from requesting an audit pursuant to Section 9.3 hereof or reviewing
the books and records of the Partnership in accordance with the terms hereof.
The Executives shall execute such further documentation as the Managing General
Partner may reasonably deem necessary to evidence such irrevocable proxies.
Notwithstanding anything contained in the Agreement to the contrary, this
Agreement shall not be amended without the consent of each Person materially and
adversely affected if such amendment would (i) convert a Limited Partner's
Partnership Interest into a General Partner's Partnership Interest, (ii) modify
the limited liability of a Limited Partner, or (iii) alter the interest of a
Partner in Profits, Losses, other items of income, gain, loss and deduction, or
any Partnership distributions, but only to the extent that such amendment has a
disproportionately larger adverse effect on such Person as compared with the
other Partners.

         8.3 OUTSIDE ACTIVITIES.

                  A Partner (including the Managing General Partner and the
General Partner) or any Affiliate thereof, and any director, officer, employee,
agent, or representative of such Partner or any Affiliate thereof, shall be
entitled to and may have business interests and engage in business activities in
addition to those relating to the Partnership, including business interests and
activities in direct competition with the Partnership. Neither the Partnership
nor any of the other Partners (including the Managing General Partner and the
General Partner) shall have any rights by virtue of this Agreement in any
business ventures of a Partner, any Affiliate thereof, or any director, officer,
employee, agent, or representative of such Partner or any Affiliate thereof.

         8.4 RETURN OF CAPITAL.

                  The Limited Partner shall not be entitled to the withdrawal or
return of its Capital Contribution except to the extent, if any, that
distributions made pursuant to this Agreement or upon termination of the
Partnership may be considered as such by law and then only to the extent
provided for in this Agreement.


                                   ARTICLE IX

         9.1 RECORDS AND ACCOUNTING.

                  The Managing General Partner shall keep or cause to be kept
appropriate books and records with respect to the Partnership's business, which
shall at all times be kept at the principal office of the Partnership or such
other office as the Managing General Partner may designate for such purposes.
Any books and records maintained by the Partnership in the regular course of its
business, including books of account and records of Partnership proceedings, may
be kept on any information storage device, provided that the books and records
so kept are convertible into clearly legible written form within a reasonable
period of time. The General Partner shall at no cost to the Partnership provide
day-to-day accounting services to the Partnership and its Controlled Entities,
and shall prepare financial and other reports reasonably requested by the
Managing General Partner. The books of the Partnership shall be maintained for
financial reporting purposes on the method of accounting approved by the
Managing General Partner in its reasonable discretion.

         9.2 FISCAL YEAR.

                  The fiscal year of the Partnership shall be the calendar year
(or relevant portion thereof with respect to the first and last years of the
Partnership) (the "Fiscal Year") for tax, accounting and other purposes.

         9.3 REPORTS.

                  The General Partner shall deliver to each Partner, at the
Partnership's expense, not later than 90 days following the end of each Fiscal
Year, a balance sheet, an income statement, and an annual statement of source
and application of funds of the Partnership for such Fiscal Year. In addition to
any and all other reports and business plans required hereunder, the General
Partner shall deliver to the Managing General Partner such reports as set forth
on Exhibit F hereof. The General Partner shall deliver to the Managing General
Partner: (i) weekly reports listed on Exhibit F hereof within seven days
following the end of such weekly period; (ii) monthly reports listed on Exhibit
F hereof within 30 days following the end of such monthly period; and (iii)
annual reports listed on Exhibit F hereof within 90 days following the end of

         10.1 PREPARATION OF TAX RETURNS.

                  The General Partner, under the supervision of the Managing
General Partner, shall arrange for the preparation and timely filing of all
returns of Partnership income, gains, deductions, losses and other items
necessary for federal, state and local income tax purposes and, in connection
therewith, the Managing General Partner shall make available to the General
Partner Partnership records necessary therefor. A copy of the Partnership's
federal income tax return will be furnished to all Partners at least 15 days
before such tax return is actually filed for their review and comment (the
Managing General Partner shall consider and may incorporate reasonable comments
made by the Partners), but in no event later than 120 days after the end of each

documents sent to or received from any taxing authority, (iii) consult with each
Limited Partner before making or implementing any material tax election or other

         10.2 TAX ELECTIONS.

                  (a) Except as otherwise provided herein, the Managing General
         Partner shall determine whether to make any election available to the
         Partnership under the Code. In connection with any transfer of a
         Partnership Interest permitted under Article XI hereof, the Managing
         General Partner shall cause the Partnership at the written request of
         the transferor or transferee, on behalf of a Partnership and at the
         time and in the manner provided in Regulations Section 1.754-1(b), to
         make an election to adjust the basis of the Partnership's property in
         the manner provided in Sections 734(b) and 743(b) of the Code, and such
         transferee shall pay all costs incurred by the Partnership in

proceedings. Notwithstanding the above, CGLH GP shall not extend the statute of
limitations with respect to any taxable years of the Partnership without the
consent of all the Partners.

                  No election shall be made by the Partnership or any Partner

of Subchapter K, Chapter 1 of Subtitle A of the Code or from any similar
provisions of any state tax laws.

                  (a) No Partnership Interest shall be transferred, in whole or
         in part, except in accordance with the terms and conditions set forth
         in Sections 11.2, 11.3, 11.4, 11.5, 11.6, 11.7, 11.8, 11.9 and 11.10.

                  (b) Any transfer or purported transfer of any Partnership
         Interest not made in accordance with this Article XI shall be null and
         void. An alleged transferee shall have no right to require any
         information or account of the Partnership's transactions or to inspect
         the Partnership's books. The Partnership shall be entitled to treat the
         alleged transferor of a Partnership Interest as the absolute owner
         thereof in all respects, and shall incur no liability to any alleged
         transferee for distributions to the Partner owning such Partnership
         Interest of record or for allocations of income, gain, losses,
         deductions or credits or for transmittal of reports and notices
         required to be given to holders of Partnership Interests. The term
         "transfer," when used in this Article XI with respect to a Partnership
         Interest, includes a sale, assignment, gift, pledge, encumbrance,
         hypothecation, mortgage, exchange, or any other disposition or
         transfer, whether voluntarily or by operation of law, at judicial sale
         or otherwise. Neither the Partnership nor the Managing General Partner
         shall keep a register of transfers of interests in the Partnership. A
         transfer of a Controlling interest in IHC GP and/or IHC LP, or any of
         its successors or assigns, shall be deemed a transfer by such Partner,
         or such successor or assign, of a Partnership Interest in the
         Partnership and subject to the restrictions hereof.

         11.2 TRANSFERS OF INTERESTS BY MANAGING GENERAL PARTNER.

                  The Managing General Partner may transfer all or a portion of
its Partnership Interest to any Person only after first obtaining the approval
of all of the Limited Partners other than the Executives (which approval may be
withheld in each such Limited Partner's sole and absolute discretion); provided,
however, that the consent of such Limited Partners shall not be required for a
transfer of the Managing General Partner's Partnership Interest: (a) as
collateral security for the indebtedness of an Affiliate of such Managing
General Partner; (b) to an Affiliate of the Managing General Partner, an
Affiliate of Sherwood M. Weiser, Karim Alibhai, Mahmood Khimji or an Affiliate
of, or investment fund or other vehicle sponsored by, Lehman Brothers; or (c)
pursuant to Sections 11.8, 11.9 and 11.10 of this Agreement. Any permitted
transfer by the Managing General Partner of its Partnership Interest under this
Section 11.2 shall not constitute a withdrawal of the Managing General Partner
under Article XII, Section 13.1(b), or any other provision of this Agreement. If
any such transfer is deemed to constitute a withdrawal under such provisions or
otherwise and results in the dissolution of the Partnership under this Agreement
or the laws of any jurisdiction to which the Partnership or this Agreement is
subject, the



                                       36
<PAGE>   126


Partners hereby unanimously consent to the reconstitution and continuation of
the Partnership immediately following such dissolution, pursuant to Section 13.2
of this Agreement.

         11.3 TRANSFERS OF INTERESTS BY GENERAL PARTNER.

                  The General Partner may transfer all, but not less than all,
of its Partnership Interest to any Person only after first obtaining the
approval of the Managing General Partner (which approval may be withheld in the
Managing General Partner's sole and absolute discretion); provided, however,
that the consent of the Managing General Partner shall not be required for a
transfer pursuant to Sections 11.8 and 11.10 of this Agreement. Any permitted
transfer by the General Partner of its Partnership Interest under this Section
11.2 shall not constitute a withdrawal of the General Partner under Article XII,
Section 13.1(b), or any other provision of this Agreement. If any such transfer
is deemed to constitute a withdrawal under such provisions or otherwise and
results in the dissolution of the Partnership under this Agreement or the laws
of any jurisdiction to which the Partnership or this Agreement is subject, the
Partners hereby unanimously consent to the reconstitution and continuation of
the Partnership immediately following such dissolution, pursuant to Section 13.2
of this Agreement.

         11.4 TRANSFER OF INTERESTS OF LIMITED PARTNER.

                  The Partnership Interests of IHC LP or the Executives, and any
of its successors or assigns, may not be transferred except: (a) if such
Partner, and any of its successors or assigns, is a natural person, by act of
law to his estate (for the benefit of an individual or other successor in
interest) or to the heir or legatee of such deceased individual; (b) if such
Partner, and any of its successors or assigns, is not an individual, upon the
adjudication of bankruptcy, dissolution or other cessation of its existence, to
the authorized representative thereof for the purpose of effecting the winding
up and disposition of the business of such entity; (c) to any other Person with
the prior written consent of the Managing General Partner and all of the Limited
Partners other than the Executives, which consent may be withheld in the sole
and absolute discretion of such Partners; (d) pursuant to the provisions of
Sections 11.8 and 11.10; and (e) in the case of the Executives, pursuant to
Section 11.12. Subject to the provisions of Sections 11.8, and 11.10, the
Partnership Interests of CGLH LP, and any of its successors or assigns, may be
transferred, in whole or in part, at the discretion of CGLH LP, or such
successor or assign.

         11.5 ADDITIONAL LIMITATIONS ON TRANSFERS OF LIMITED PARTNERSHIP
              INTERESTS.

                  The Managing General Partner may require, as a condition to
any transfer of a Partnership Interest of a Partner, that, in the Managing
General Partner's reasonable determination: (a) the transfer will not jeopardize
the treatment of the Partnership as a partnership not treated as a corporation
for federal income tax purposes; (b) the transfer will not result in or cause a
termination of the Partnership for federal income tax purposes; and (c) the
transfer will not violate the registration requirements of applicable securities
laws or cause any prior offer and sale of Partnership Interests to violate such
requirements. The Managing General Partner may also require the proposed
transferee to deliver to the Partnership acceptable representations and
warranties respecting its status under applicable securities laws and its
investment intent with respect to the Partnership Interest, and may require the
transferor and transferee to supply such other documentation as the Managing
General Partner may deem advisable in its sole discretion.

         11.6 DISTRIBUTIONS AND ALLOCATIONS IN RESPECT OF TRANSFERRED
              PARTNERSHIP INTERESTS.

                  If any Partnership Interest is transferred during any Fiscal
Year in compliance with the provisions of this Article XI, Profits, Losses, and
all other items attributable to the transferred interest for such period shall
be divided and allocated between the transferor and the transferee by taking
into account their varying interests during the period in accordance with Code
Section 706(d), using any



                                       37
<PAGE>   127


conventions permitted by law, selected by the Managing General Partner in its
reasonable discretion. All distributions on or before the date of such transfer
shall be made to the transferor. Solely for purposes of making such allocations
and distributions, the Partnership shall recognize such transfer not later than
the end of the calendar month during which it is given notice of such transfer,
provided that if the Partnership does not receive a notice stating the date such
Partnership Interest was transferred and such other information as the Managing
General Partner may reasonably require within 30 days after the end of the
Fiscal Year during which the transfer occurs, then all of such items shall be
allocated, and all distributions shall be made, to the person who, according to
the books and records of the Partnership, on the last day of the Fiscal Year
during which the transfer occurs, was the owner of the Partnership Interest.
Neither the Partnership nor any Partner shall incur any liability for making
allocations and distributions in accordance with the provisions of this Section
11.6, whether or not any Partner or the Partnership has knowledge of any
transfer of ownership of any Partnership Interest.

         11.7 ADMISSION OF SUBSTITUTE OR SUCCESSOR PARTNERS.

                  (a) Admission of Substitute Limited Partners. A transferee
         (which may be the heir or legatee of the Limited Partner) or assignee
         of the Limited Partner's Partnership Interest, or Person acquiring a
         Partnership Interest pursuant to any foreclosure made upon any
         permitted pledge or hypothecation of such Partnership Interest, shall
         be entitled to receive the distributive share of the Partnership's
         Profits, Losses, income, gains, losses, deductions, and credits
         attributable to such Partnership Interest. To become a substitute
         Limited Partner, such transferee, assignee, heir, or legatee must be
         acceptable to the Managing General Partner in the Managing General
         Partner's sole and absolute discretion. If acceptable to the Managing
         General Partner, such transferee, assignee, heir, or legatee shall
         execute a counterpart of this Agreement, thereby agreeing to be bound
         by the terms hereof as a Limited Partner with respect to the
         Partnership Interest so transferred. Upon admission of a substitute
         Limited Partner, such Limited Partner shall be subject to all of the
         restrictions applicable to, shall assume all of the obligations of, and
         shall attain the status of a Limited Partner under and pursuant to this
         Agreement with respect to the Partnership Interest held by such Limited
         Partner.

                  (b) Admission of Successor Managing General Partner. A
         successor Managing General Partner selected pursuant to Section 13.2 of
         this Agreement or the permitted transferee of or successor to the
         Partnership Interest of the Managing General Partner pursuant to
         Section 11.2 of this Agreement shall be admitted to the Partnership as
         the Managing General Partner, effective as of the date of the
         withdrawal or removal of the predecessor Managing General Partner or
         the date of transfer of such predecessor's Partnership Interest.

                  (c) Admission of Successor General Partner. A successor
         General Partner selected pursuant to Section 13.2 of this Agreement or
         the permitted transferee of or successor to all of the Partnership
         Interest of the General Partner pursuant to Section 11.3 of this
         Agreement shall be admitted to the Partnership as the General Partner,
         effective as of the date of the withdrawal or removal of the
         predecessor General Partner or the date of transfer of such
         predecessor's Partnership Interest.

                  (d) Action by Managing General Partner. In connection with the
         admission of any substitute Limited Partner, successor General Partner
         or successor Managing General Partner, the Managing General Partner
         shall have the authority to take all such actions as it deems necessary
         or advisable in connection therewith, including the amendment of
         Exhibit A to this Agreement and the execution and filing with
         appropriate authorities of any necessary documentation.

         11.8 BUY-SELL PROVISION.

                  (a) If a Partner wishes at any time after the Buy-Sell Date,
         for any reason or for no reason, to purchase the Partnership Interests
         of another Partner or other Partners (for the purposes of this Section
         11.8, the "Offering Partner"), the following procedure shall apply to
         such proposed purchase:

                           (i) The Offering Partner shall give notice (the
                  "Buy-Sell Notice") to the Partner or Partners whose
                  Partnership Interests the Offering Partner seeks to purchase
                  (individually or collectively, the "Receiving Partner")
                  specifying a gross value (i.e., without taking into account
                  liabilities) (the "Stated Value") attributable to all of the
                  assets of the Partnership. The Buy-Sell Notice must be
                  delivered with the words "Confidential/Urgent" clearly visible
                  from the exterior of the container in which the Buy-Sell
                  Notice is contained and must expressly alert the Receiving
                  Partner to the duration of the Response Period (as defined
                  below). Delivery shall be in accordance with the notice
                  provisions of this Agreement.

                           (ii) The Receiving Partner shall have the options (A)
                  to require that the Offering Partner purchase all of the
                  Partnership Interests of the Receiving Partner and the
                  Partnership Interests of its Affiliates; or (B) to elect to
                  purchase the Offering Partner's Partnership Interest and those
                  of its Affiliates. If the Receiving Partner elects to purchase
                  the Offering Partner's Partnership Interest and those of the
                  Offering Partner's Affiliates or require the purchase of all
                  of its Partnership Interests and its Affiliate's Partnership
                  Interests, the Receiving Partner shall so notify the Offering
                  Partner in writing within 30 days from the receipt of the
                  Buy-Sell Notice (the "Response Period") and, in the case of
                  the election to acquire the Offering Partner's Partnership
                  Interests and those of its Affiliates, the Partnership
                  Interests being acquired shall be those of the Offering
                  Partner and its Affiliates. The Partner purchasing the
                  Partnership Interests of other Partner(s) pursuant to this
                  Section 11.8 shall be the "Buying Partner" and the Partner(s)
                  selling Partnership Interests pursuant to this Section 11.8
                  shall be the "Selling Partner". Unless the Receiving Partner
                  responds within the Response Period that it will be the Buying
                  Partner or requiring the purchase of the Partnership Interests
                  of its Affiliates, (A) the Offering Partner will be the Buying
                  Partner, (B) the Receiving Partner will be the Selling Partner
                  and (C) the Partnership Interests being acquired shall be only
                  those set forth in the Buy-Sell Notice.

                           (iii) Within 75 days after the Buy-Sell Notice has
                  been given, the Buying Partner shall pay to the Selling
                  Partner (and, if applicable, the Selling Partner's Affiliates
                  in this Partnership), in full payment for its (and, if
                  applicable, their) interest(s) in this Partnership, the
                  amounts that such Selling Partner (and, if applicable, the
                  Selling Partner's Affiliates in this Partnership) would have
                  received if the assets of the Partnership had been sold for an
                  amount equal to the Stated Value on the date of such payment,
                  Profit, Loss, and other items of income, gain, loss or
                  deduction were allocated among the Partners in accordance with
                  this Agreement and the proceeds of such sale (net of
                  liabilities that would have been paid out of such proceeds,
                  including without limitation any amounts due to a Partner
                  (and, if applicable, the Selling Partner's Affiliates in this
                  Partnership), if such sale had actually occurred) were
                  distributed in accordance with the provisions of this
                  Agreement.

                           (v) If the Receiving Partner elects to be the Buying
                  Partner but fails to complete the transaction as described
                  above, the Offering Partner shall be entitled to be the Buying
                  Partner as described above.

                           (vi) The purchase price to be paid under this Section
                  11.8 shall be payable entirely in cash at the closing of the
                  sale of interests. The Selling Partner shall represent to the
                  Buying Partner that the Partnership Interests being sold are
                  free and clear of liens other than those liens in connection
                  with guaranties of the Partnership's indebtedness or otherwise
                  pursuant to Article XI hereof. Upon the Buying Partner's
                  tender of payment of the purchase price, including, without
                  limitation, by wire transfer or delivery of a certified check
                  to the Selling Member's address on the records of the
                  Partnership, the Selling Partner (and, if applicable, the
                  Selling Partner's Affiliates in this Partnership) shall be
                  deemed to have transferred its (or, if applicable, their)
                  Partnership Interest(s) and shall cease to be a Partner (or,
                  if applicable, Partners) of this Partnership (or to have any
                  economic or other interest therein).

                           (vii) Notwithstanding anything to the contrary
                  herein, an Executive may only be a Buying Partner with the
                  consent of all of the other Partners.

         11.9 RIGHT TO REQUIRE SALE.

                  (a) Upon, and for the two-year period after, the occurrence of
         a Change in Control, CGLH LP and CGLH GP shall have the right to
         require IHC to purchase all, but not less than all, of the Partnership
         Interests held by such entity(ies) for cash at the purchase price
         determined pursuant to Section 11.9(b) hereof. Such right shall be
         exercised by delivery of a written notice by CGLH LP and CGLH GP to IHC
         GP and IHC LP, respectively, that CGLH LP and CGLH GP elects to
         exercise their right under this Section 11.9. The date of such notice
         shall be the "Put Date".

                  (b) The purchase price to be paid shall be equal to the total
         amount, determined as of the Put Date, that a willing buyer would pay
         to a willing seller for CGLH LP's and CGLH GP's Partnership Interests,
         taking into account assumed liabilities, determined as a whole and in
         the context of the Partnership as a going concern in an arm's length,
         negotiated transaction without undue time constraints (the "Purchase
         Price"). In determining the Purchase Price, no discounts for lack of
         control or lack of marketability shall be applied. The Purchase Price
         shall be determined jointly by CGLH GP and CGLH LP, on the one hand,
         and IHC, on the other hand. If there is a dispute between these parties
         as to the Purchase Price (which dispute remains unresolved for 10
         Business Days), such dispute shall be submitted for final determination
         to a mutually acceptable investment banking firm of national reputation
         familiar with the valuation of companies in the hospitality and lodging
         industry ("Investment Banking Firm"). In the event that these parties
         cannot agree on a mutually acceptable Investment Banking Firm within 10
         Business Days, CGLH GP and CGLH LP, on the one hand, and IHC GP and IHC
         LP, on the other hand, shall each select one Investment Banking Firm,
         and shall cause such firms to promptly select a third Investment
         Banking Firm within five Business Days. The three Investment Banking
         Firms so selected shall, by majority vote, render their final
         determination as promptly as practicable and in any event within 20
         Business Days, which determination shall be final and binding on the
         parties. The fees and expenses of any such determination shall be borne
         by equally by CGLH GP and CGLH LP, on the one hand, and IHC GP and IHC
         LP, on the other hand.

                  (c) Upon the closing of the sale under this Section 11.9, CGLH
         LP and CGLH GP shall thereupon cease to be Partners of the Partnership
         (or to have any economic or other interest therein).

         11.10 TAG-ALONG RIGHT.

                  (a) In connection with the sale or syndication of any of CGLH
         GP's and/or CGLH LP's Partnership Interests to an unrelated third party
         (a "Sale"), IHC LP, IHC GP and the



                                       40
<PAGE>   130


         Executives shall be afforded the opportunity to participate in such
         Sale as and to the extent provided in this Agreement. At least twenty
         (20) days prior to the consummation of the Sale, CGLH shall send a
         written notice (a "Sale Notice") to IHC LP, IHC GP and the Executives
         setting forth the terms of the Sale, including the percentage of
         Partnership Interests being transferred and the purchase price offered
         by such unrelated third party. IHC LP, IHC GP and the Executives shall
         have twenty days from the date of the Sale Notice (the "Notice Period")
         within which to exercise the right to participate in the Sale. Each of
         IHC GP and IHC LP shall have the right to transfer such portion of its
         Partnership Interests as relates to its Class A Capital Contributions
         equal to the same percentage as being transferred by CGLH GP and/or
         CGLH LP (the "IHC Tag-Along Interest"). Each Executive shall have the
         right to transfer such portion of such Executive's Partnership Interest
         equal to the same percentage as being transferred by CGLH GP and/or
         CGLH LP(an "Executive Tag-Along Interest"). Neither the IHC Tag-Along
         Interest nor an Executive Tag-Along Interest shall include any
         interests or amounts related to Class B Capital Contributions,
         Undistributed Class B Capital, Class B Preference Amounts or
         Undistributed Class B Preference Amounts and no such interests or
         amounts shall be included in the consideration paid (or the calculation
         thereof) in respect of the IHC Tag-Along Interest or an Executive
         Tag-Along Interest. If IHC LP, IHC GP shall elect to participate in the
         Sale, it (or they) shall receive, as consideration therefor, the
         product of: (i) the purchase price set forth in the Sale Notice and
         (ii) the fraction, (A) the numerator of which is the IHC Tag-Along
         Interest, and (B) the denominator of which is the sum of (1) CGLH GP's
         and/or CGLH LP's Partnership Interests being transferred pursuant to
         the Sale and (2) the IHC Tag-Along Interest. If an Executive shall
         elect to participate in the Sale, he shall receive, as consideration
         therefor, the product of: (i) the purchase price set forth in the Sale
         Notice and (ii) the fraction, (A) the numerator of which is his
         Executive Tag-Along Interest, and (B) the denominator of which is the
         sum of (1) CGLH GP's and/or CGLH LP's Partnership Interests being
         transferred pursuant to the Sale and (2) such Executive Tag-Along
         Interest.

                  (b) If: (i) IHC GP and IHC LP elect to participate in the
         proposed Sale, (ii) the Sale would result in the transfer of all of IHC
         GP's and IHC LP's Partnership Interests and (iii) the termination of
         one or more property management agreements between the Manager and the
         Partnership or a Controlled Entity covering a Hotel (and its other,
         related assets) arises therefrom, CGLH GP and/or CGLH LP shall, upon
         consummation of the Sale, pay to the Partnership an amount equal to IHC
         LP's Undistributed Class B Capital invested in the Hotel, and other
         related assets as to which a property management agreement has been
         terminated as a result of the Sale. The Partnership shall distribute
         such amount to IHC LP in reduction of its Undistributed Class B
         Capital. The Partners and the Partnership acknowledge and agree that
         each of CGLH GP and CGLH LP has the right to consummate a Sale or other
         transfer, notwithstanding any termination of, or penalty with respect
         to, property management agreements or other agreements that may arise
         therefrom and without any liability with respect to any such
         termination or penalty.

                  (c) If IHC GP, IHC LP and/or the Executives elect to
         participate in the proposed Sale (to the extent of the IHC Tag-Along
         Interest or Executive Tag-Along Interest(s), as applicable), then IHC
         GP and/or IHC LP or an Executive, as applicable, shall give notice of
         such election by a signed writing by such electing party (the
         "Acceptance"). Any Acceptance shall be received by CGLH GP and/or CGLH
         LP prior to the end of the Notice Period. After the lapse of the Notice
         Period within which CGLH GP and/or CGLH LP shall not have received an
         Acceptance from IHC LP, IHC GP and/or the Executives, CGLH may
         consummate, without the participation of such party, a Sale to one or
         more purchasers, for consideration equal to or less than the purchase
         price specified in the Sale and on terms no more favorable to CGLH GP
         and/or CGLH LP than those specified in the Sale Notice. In the event
         CGLH GP's and/or CGLH LP's Partnership Interests covered by the Sale
         Notice are not disposed of within ninety (90) days following the lapse
         of the Notice Period, then they shall once again be subject to the
         tag-along rights set forth in this section.

                  (d) In connection with a Sale pursuant to which IHC GP and/or
         IHC LP exercises its right to "tag along" pursuant to this Section
         11.10 (and notwithstanding that an Executive did not exercise his right
         to "tag-along" pursuant to this Section 11.10), CGLH LP and/or CGLH GP
         may elect to require that the Executives, or either of them,
         participate in such Sale, as if such Executive(s) elected to
         "tag-along" pursuant to the other subsections of this Section 11.10.

         11.11 REDUCTION OF UNDISTRIBUTED CLASS B CAPITAL.

                  Except as otherwise provided in Section 11.10 of this
Agreement, if a property management agreement with a Manager is terminated for
any reason (including without limitation the failure by the Manager to meet
performance standards contained in such property management agreement), the
Partnership shall distribute to the holders of the Undistributed Class B Capital
an amount equal to such holders' Undistributed Class B Capital invested in the
Hotel and its other, related assets with respect to which the property
management agreement was terminated by the Partnership.

         11.12 OPTIONAL REDEMPTION.

                  Upon the termination of an Executive's employment with the
Corporation for any reason (including, without limitation, death, Cause, without
Cause, without Good Reason, with Good Reason or Disability, as such terms are
defined in such Executive's Executive Employment Agreement), the Partnership
shall have the right (but not the obligation) to acquire such Executive's
Percentage Interest in the Partnership as of the date immediately following the
date of such termination (i.e., after giving effect to the reduction in
Percentage Interest, if any, resulting from such termination) (such interest,
the "Redemption Interest"), for a purchase price (and subject to the amount of
such purchase price) determined pursuant to Section 11.12(a) and (h) hereof (the
"Redemption Price") as of the Redemption Closing Date. The following procedure
shall apply to such proposed acquisition:

                           (a) Upon the termination of an Executive's employment
         with the Corporation as a result of such Executive's death or
         Disability, without Cause or with Good Reason (as such terms are
         defined in such Executive's Executive Employment Agreement), the
         Redemption Price shall equal the greater of: (i) such Executive's
         Undistributed Tier 2 Capital allocable to his Redemption Interest and
         (ii) the fair market value of such Executive's Redemption Interest
         determined in accordance with Section 11.12(h) hereof. Upon the
         termination of an Executive's employment with the Corporation for Cause
         or without Good Reason (as such terms are defined in such Executive's
         Executive Employment Agreement), the Redemption Price shall equal the
         fair market value of such Executive's Redemption Interest determined in
         accordance with Section 11.12(h) hereof.

                           (b) The Partnership shall give notice (the
         "Redemption Notice") to such Executive of the Partnership's intent to
         acquire such Executive's Redemption Interest, subject to the
         determination of the fair market value thereof determined pursuant to
         Section 11.12(h). Delivery of the Redemption Notice shall be in
         accordance with the notice provisions of this Agreement.

                           (c) Within 75 days after the Redemption Notice has
         been given (or within 75 days after the delivery of a certified
         appraisal to the Partnership of the fair market value of the
         Executive's Redemption Interest as of the Redemption Date, if, after
         receipt of the appraisal, the Partnership elects to continue with the
         acquisition of the Redemption Interest), the Partnership shall pay to
         such Executive the Redemption Price, in full payment for his Redemption
         Interest



                                       42
<PAGE>   132


         and the Redemption Interest shall be assigned to the Partnership (such
         date, the "Redemption Closing Date"). The Redemption Price shall be
         payable entirely in cash. Such Executive shall represent to the
         Partnership that the Redemption Interests being sold are free and clear
         of liens other than those liens in connection with guaranties of the
         Partnership's indebtedness or otherwise pursuant to Article XI hereof.

                           (d) Upon the Partnership's tender of payment of the
         Redemption Price, including, without limitation, by wire transfer or
         delivery of a certified check to such Executive's address on the
         records of the Partnership, such Executive shall be deemed to have
         transferred his entire Partnership Interest and shall cease to be a
         Partner or to have any economic or other interest herein.

                           (e) Such Executive's only remedy in connection with a
         dispute arising under this Section (including, without limitation, any
         dispute over the Redemption Price) shall be for damages. The Partners
         agree that the remedy described herein bears a reasonable relationship
         to the damages which the Partners estimate may be suffered by an
         Executive for a breach by the Partnership under this Section and the
         limitation of remedy is not unreasonable under the circumstances
         existing as of the date hereof.

                           (f) The then existing Percentage Interests of the
         remaining Partners (other than an Executive) shall be proportionately
         increased to reflect the redemption of such Redemption Interest.

                           (g) For the purposes of this Section 11.12,
         "Executive's Percentage Interest" shall include any transferee of an
         Executive who is a spouse, natural or adopted child, grandchild,
         parent, sibling or natural or adopted child of any sibling of
         Executive, or trust for the benefit of any one of the foregoing
         persons, or his estate or designated beneficiary, heir or legatee.
         Nothing in this Section shall create a right of transfer contrary to
         the other provisions of Article XI or otherwise.

                           (h) The fair market value of an Executive's
         Redemption Interest shall be determined by agreement between the
         Partnership and such Executive. In the absence of an agreement within
         30 days following the date of the Redemption Notice, the following
         procedure shall apply: The value of an Executive's Redemption Interest
         as of the Redemption Closing Date shall be determined pursuant to an
         appraisal performed by an appraiser of recognized standing in the
         hospitality industry, selected by the Partnership in its reasonable
         discretion. If such appraiser is not reasonably acceptable to such
         Executive, such Executive shall so notify the Partnership and such
         Executive shall select a second appraiser of recognized standing in the
         hospitality industry. If, within ten days following notice to such
         Executive of the selection of an appraiser by the Partnership, such
         Executive does not notify the Partnership that such appraiser is not
         acceptable, such appraiser shall be deemed reasonably satisfactory to
         the Executive. If such Executive selects a second appraiser (as
         provided herein), such two appraisers shall jointly select a third
         appraiser of recognized standing in the hospitality industry and such
         third appraiser shall be the appraiser for purposes of this Section
         11.12. The appraiser selected by the Partnership, or the third
         appraiser selected pursuant to this paragraph, as the case may be,
         shall, within 60 days from the date of the Redemption Notice, complete
         and deliver to the Executive and the Partnership certified copies of
         the appraisal of the fair market value of the Executive's Redemption
         Interest as of the Redemption Date. The costs of the appraisal shall be
         borne by the Partnership. In order to determine the fair market value
         of the Executive's Redemption Interest, the appraiser shall determine
         the amount of cash the Executive would be entitled to receive under
         Section 13 hereof if (i) the Partnership sold all of its property for
         an amount of cash equal to the



                                       43
<PAGE>   133


         aggregate value of all hotels and other property owned by the
         Partnership, and paid or reserved for all liabilities of the
         Partnership, and the Partnership received liquidation value for its
         interests in entities in which the Partnership owns a direct or
         indirect interest and (ii) the Partnership thereafter liquidated in
         accordance with Section 13 hereof.

         11.13 TERMINATION FOR CAUSE AND WITHOUT GOOD REASON.

                  If the Corporation terminates an Executive for Cause (as such
term is defined in such Executive's Executive Employment Agreement) or if an
Executive terminates his employment with the Corporation without Good Reason (as
such term is defined in such Executive's Executive Employment Agreement), then
such Executive's Percentage Interest shall be reduced as of the date of such
termination, pursuant to Exhibit G hereto; provided, however, that if such
Percentage Interest has been reduced below the percentage provided on Exhibit G
hereto pursuant to the terms of this Agreement (by way of example and not as a
limitation, if such Executive's Percentage Interest has been diluted pursuant to
Section 4.3(b)) then such Executive's Percentage Interest shall equal such
lesser Percentage Interest. The then existing Percentage Interests of the
Partners (other than the Executives) shall each be increased by one-half of the
percentage by which such Executive's Percentage Interest is reduced. In any and
all events, such terminated Executive's Percentage Interest, if any, as reduced
hereby, shall be subject to optional redemption by the Partnership pursuant to
Section 11.12.

                                  ARTICLE XII

     WITHDRAWAL AND REMOVAL OF MANAGING GENERAL PARTNER AND GENERAL PARTNER

         12.1 EVENTS OF WITHDRAWAL.

                  (a) Neither the Managing General Partner nor the General
         Partner may voluntarily withdraw from the Partnership at any time. The
         Managing General Partner or the General Partner (as the case may be),
         however, will be deemed to have withdrawn from the Partnership on the
         occurrence of any one of the following events (each event herein
         referred to as an "Event of Withdrawal"):

                           (i) Pursuant to Section 12.2 hereof, the Managing
                  General Partner is removed as managing general partner of the
                  Partnership, or the General Partner is removed as general
                  partner of the Partnership; or

                           (ii) The Managing General Partner transfers all of
                  its right, title and interest as managing general partner of
                  the Partnership other than as permitted by Article XI; or

                           (iii) The General Partner transfers all of its right,
                  title and interest as general partner of the Partnership other
                  than as permitted by Article XI.



                                       44
<PAGE>   134


                  (b) Upon an Event of Withdrawal with respect to the General
         Partner, there shall be no dissolution of the Partnership, and if such
         dissolution is otherwise mandated by applicable law, the remaining
         Partners agree that they will be deemed to have unanimously elected to
         continue the Partnership and the Partnership shall be deemed to be
         dissolved and reconstituted as may be required by applicable law.

         12.2 REMOVAL.

                  (a) A Managing General Partner may be removed as Managing
         General Partner and a General Partner may be removed as General Partner
         at any time: (i) after such Person commits an act of fraud or gross
         negligence in its capacity as Managing General Partner or General
         Partner, as the case may be; (ii) after such Person commits a material
         breach of this Agreement; (iii) after such Person engages in
         intentional and willful misconduct against the interests of the
         Partnership; (iv) after such Person suffers or is subject to an Event
         of Bankruptcy; or (v) with respect to the General Partner only, upon
         the vote of a Majority Interest to remove the General Partner if the
         General Partner exceeds the power or authority expressly granted herein
         or the power or authority expressly granted by the Managing General
         Partner in writing, or purports to have power or authority in excess of
         those expressly granted herein or the power or authority expressly
         granted by the Managing General Partner in writing.

                  (b) Any such removal of that Person as the Managing General
         Partner or the General Partner shall be effective after the following
         conditions have been satisfied: (i) delivery of a removal notice to
         such Person, in the case of the removal of the Managing General
         Partner, from a Majority Interest, and in the case of the General
         Partner, from the Managing General Partner; and (ii) in the case of the
         Managing General Partner, approval by a Majority Interest of a new
         Managing General Partner and the admission of such Person as a Managing
         General Partner in the Partnership. The removal of the Managing General
         Partner shall cause a dissolution event under Section 13.1 of this
         Agreement.

                  (c) If a Person is removed as a General Partner but continues
         to own a Partnership Interest, then such Partnership Interest shall be
         converted into a Partnership Interest as a Limited Partner. In the
         event of a reconstitution of the Partnership pursuant to Section 13.2
         of this Agreement, the Partnership Interest of a removed Managing
         General Partner shall be converted into a Partnership Interest as a
         Limited Partner.

                  (d) If a Person is removed as a General Partner, such Person
         shall perform, execute and deliver or cause to be performed, executed
         and delivered any and all acts, documents and assurances as the
         Managing General Partner may reasonably require to evidence: (i) the
         removal of the former General Partner; and (ii) if applicable, a
         conversion of the Partnership Interest of the former General Partner to
         a Partnership Interest as a Limited Partner. If a Person is removed as
         a Managing General Partner, and thereafter the Partnership is
         reconstituted pursuant to Section 13.2 of this Agreement, such Person
         shall perform, execute and deliver or cause to be performed, executed
         and delivered any and all acts, documents and assurances as the newly
         appointed Managing General Partner may reasonably require to evidence:
         (i) the removal of the Managing General Partner; and (ii) if
         applicable, a conversion of the Partnership Interest of the former
         Managing General Partner to a Partnership Interest as a Limited
         Partner; and (iii) the admission of a new Managing General Partner.

                  (e) Notwithstanding anything to the contrary in Article XI, in
         connection with the admission of a new Managing General Partner, the
         Limited Partners may assign a portion of their respective Partnership
         Interests to such new Managing General Partner so that such new
         Managing General Partner has at least a 1% Percentage Interest in all
         items of Profit, Loss,



                                       45
<PAGE>   135


         income, gain, loss and deduction, Partnership capital, and
         distributions. The portion of the Partnership Interest of a Limited
         Partner that is assigned to such new Managing General Partner shall be
         converted into a Partnership Interest as a Managing General Partner
         upon its receipt by the new Managing General Partner.

                                  ARTICLE XIII

                           DISSOLUTION AND WINDING UP

         13.1 DISSOLUTION.

                  (a) Except as otherwise provided in this Agreement, no Partner
         shall have the right to terminate this Agreement or dissolve the
         Partnership by its express will or by withdrawal without the prior
         written consent of the other Partners.

                  (b) The Partnership shall be dissolved upon the first to occur
         of any of the following:

                           (i) The expiration of its term as provided in Section
                  1.3 of this Agreement (as such term may have been extended in
                  accordance with the provisions of Section 1.3 prior to an
                  event of dissolution);

                           (ii) The removal of the Managing General Partner, or
                  any other event that results in its ceasing to be the managing
                  general partner of the Partnership;

                           (iii) An election to dissolve the Partnership by the
                  Managing General Partner that is approved by all of the
                  Limited Partners other than the Executives;

                           (iv) At the election of CGLH GP, at such time as CGLH
                  Partners I LP, CGLH Partners II LP and their Affiliates cease
                  to Beneficially Own Voting Securities representing at least
                  30% or more of the Total Voting Power (without taking into
                  account any limitation on the conversion of such Voting
                  Securities in determining such Beneficial Ownership or the
                  number of shares issuable upon complete conversion); or

                           (v) Any other event, under the Delaware Act, that
                  would require (notwithstanding provisions in this Agreement to
                  the contrary) the Partnership's dissolution.

         13.2 CONTINUATION OF THE PARTNERSHIP.

                  (a) Except as otherwise provided in this Agreement, upon the
         occurrence of an event described in Section 13.1(b)(i), (b)(ii) or
         (b)(v), the Partnership shall be deemed to be dissolved and
         reconstituted only if 50.1% of the Percentage Interests of the
         remaining Partners elect to continue the Partnership within 90 days of
         such event. If no election to continue the Partnership is made within
         90 days of such event, the Partnership shall conduct only those
         activities necessary to wind up its affairs. If an election to continue
         the Partnership is made upon the occurrence of an event described in
         Section 13.1(b)(i), (b)(ii) or (b)(v), then:

                           (i) If there is no remaining Managing General Partner
                  as a result of Section 13.1(b)(ii), then within such 90 day
                  period a successor Managing General Partner shall be selected
                  by a Majority Interest (if such Partners cannot agree on the
                  selection of a successor Managing General Partner, the
                  Partnership shall be dissolved and liquidated);



                                       46
<PAGE>   136


                           (ii) The Partnership shall be deemed to be
                  reconstituted and shall continue until the end of the term for
                  which it is formed unless earlier dissolved in accordance with
                  this Article XIII;

                           (iii) If dissolution occurred pursuant to Section
                  (b)(ii), the withdrawn Managing General Partner shall be
                  automatically admitted to the Partnership as a Limited Partner
                  and its former Partnership Interest as a Managing General
                  Partner shall be automatically converted to a Limited
                  Partner's Partnership Interest in the manner provided in
                  Section 12.2 of the Agreement; and

                           (iv) All necessary steps shall be taken to amend or
                  restate this Agreement and the Certificate.

                  (b) Upon an Event of Withdrawal with respect to the General
         Partner or an Event of Withdrawal other than removal with respect to
         the Managing General Partner, there shall be no dissolution of the
         Partnership, and if such dissolution is otherwise mandated by
         applicable law, the remaining Partners agree that they will be deemed
         to have unanimously elected to continue the Partnership and the
         Partnership shall be deemed to be dissolved and reconstituted as may be
         required by applicable law.

         13.3 LIQUIDATION.

                  (a) Upon dissolution of the Partnership, unless the
         Partnership is continued under Section 13.2 of this Agreement, the
         Partnership's affairs shall be wound up. A Person selected by a
         Majority Interest shall be the liquidator (the "Liquidator"). The
         Liquidator shall be entitled to receive such compensation for its
         services as may be approved by all of the Limited Partners other than
         the Executives.

                  (b) The Liquidator shall agree not to resign at any time
         without 15 days' prior written notice and may be removed at any time,
         with or without cause, by notice of removal approved by a Majority
         Interest. Upon dissolution, removal, or resignation of the Liquidator,
         a successor and substitute Liquidator (who shall have, and succeed to,
         all rights, powers, and duties of the original Liquidator) shall within
         30 days thereafter be selected by a Majority Interest. The right to
         appoint a successor or substitute Liquidator in the manner provided
         herein shall be recurring and continuing for so long as the functions
         and services of the Liquidator are authorized to continue under the
         provisions hereof, and every reference herein to the Liquidator will be
         deemed to refer also to any such successor or substitute Liquidator
         appointed in the manner herein provided.

                  (c) Except as expressly provided in this Article XIII, the
         Liquidator appointed in the manner provided herein shall have and may
         exercise, without further authorization or consent of any of the
         parties hereto, all of the powers conferred upon the Managing General
         Partner under the terms of this Agreement (but subject to all of the
         applicable limitations, contractual and otherwise, upon the exercise of
         such powers) to the extent necessary or desirable in the good faith
         judgment of the Liquidator to carry out the duties and functions of the
         Liquidator hereunder for and during such period of time as shall be
         reasonably required in the good faith judgment of the Liquidator to
         complete the winding up and liquidation of the Partnership.

                  (d) The Liquidator shall liquidate the assets of the
         Partnership and apply and distribute the proceeds of such liquidation
         in the following order of priority, unless otherwise required by
         mandatory provisions of applicable law:



                                       47
<PAGE>   137


                           (i) To the payment of the expenses of the terminating
                  transactions including, without limitation, brokerage
                  commissions, legal fees, accounting fees and closing costs;

                           (ii) To the payment to creditors of the Partnership,
                  including Partners, in order of priority provided by law; and

                           (iii) To the Partners and assignees in accordance
                  with the manner in which proceeds from a Capital Event are
                  distributed pursuant to Section 6.1(b)(ii) hereof; provided,
                  however, that any Available Cash, on hand at the time of the
                  event of dissolution giving rise to the liquidation of the
                  Company and during the term of such liquidation, from the
                  operations of any Hotels and other, related assets or
                  otherwise not from a Capital Event shall be distributed in
                  accordance with the manner in which Available Cash is
                  distributed pursuant to Section 6.1(b)(i); provided, further,
                  however, that the Liquidator may place in escrow a reserve of
                  cash or other assets of the Partnership for contingent
                  liabilities in an amount determined by the Liquidator to be
                  appropriate for such purposes.

         13.4 DISTRIBUTION IN KIND.

                  Notwithstanding the provisions of Section 13.3 of this
Agreement which require the liquidation of the assets of the Partnership, but
subject to the order of priorities set forth therein, if on dissolution of the
Partnership the Liquidator determines (and if the Liquidator is the Managing
General Partner, then if the Liquidator determines after consultation with the
Limited Partners) that an immediate sale of part or all of the Partnership's
assets would be impractical or would cause undue loss to the Partners and
assignees, the Liquidator may defer for a reasonable time the liquidation of any
assets except those necessary to satisfy liabilities of the Partnership (other
than those to Partners) and/or may distribute to the Partners and assignees, in
lieu of cash, as tenants in common and in accordance with the provisions of
Section 13.3 of this Agreement, undivided interests in such Partnership assets
as the Liquidator deems not suitable for liquidation. Any such distributions in
kind shall be subject to such conditions relating to the disposition and
management of such properties as the Liquidator deems reasonable and equitable
and to any joint operating agreements or other agreements governing the
operation of such properties at such time. The Liquidator shall determine the
fair market value of any property distributed in kind using such reasonable
method of valuation as it may adopt.

         13.5 CANCELLATION OF CERTIFICATE OF LIMITED PARTNERSHIP.

                  Upon the completion of the distribution of Partnership
property as provided in Section 13.3 and Section 13.4 of this Agreement, the
Partnership shall be terminated, and the Liquidator (or the Managing General
Partner and Limited Partners if necessary) shall cause the cancellation of the
Certificate in the State of Delaware and of all qualifications and registrations
of the Partnership as a foreign limited partnership in jurisdictions other than
the State of Delaware and shall take such other actions as may be necessary to
terminate the Partnership.

         13.6 RETURN OF CAPITAL.

                  Except as otherwise provided in Section 4.5, neither the
Managing General Partner nor the General Partner shall be personally liable for
the return of the Capital Contributions, or any portion thereof, it being
expressly understood that any such return shall be made solely from Partnership
assets.

         13.7 CERTAIN TERMINATIONS.

                  Notwithstanding any other provisions of this Article XIII, in
the event the Partnership is terminated within the meaning of Code Section
708(b)(1)(B), but no event requiring liquidation has occurred, the Partnership
shall not be liquidated, the Partnership's liabilities shall not be paid or
discharged, and the Partnership's affairs shall not be wound up.

                                   ARTICLE XIV

                        AMENDMENT OF AGREEMENT; CONSENTS

         14.1 AMENDMENT PROCEDURES.

                  Except as provided in Section 1.2 of this Agreement and the
amendments to Exhibit A and Exhibit B hereto, all amendments to this Agreement
shall be in accordance with the following requirements: (a) amendments to this
Agreement may be proposed only by a Partner; (b) if an amendment is proposed,
the Managing General Partner shall seek the written consent of the requisite
Percentage Interests of Limited Partners and as may be required under any debt
instruments pursuant to which the Partnership is debtor; (c) a proposed
amendment shall be effective upon its approval by: (i) the Managing General
Partner and the General Partner, and (ii) all of the Limited Partners; and (d)
the Managing General Partner shall notify all Partners upon final adoption of
any such proposed amendment.

         14.2 ACTION WITHOUT A MEETING.

                  Any action that that requires the consent of all of the
Partners may be taken without a meeting if a consent in writing setting forth
the action so taken is signed by Limited Partners owning not less than the
minimum Percentage Interests that would be necessary to authorize or take such
action pursuant to the terms of this Agreement. To the extent that the laws of
any jurisdiction to which the Partnership or the Partnership Agreement is
subject require that any action of Limited Partners under this Agreement be
unanimous, any action taken by Limited Partners pursuant to and in accordance
with the preceding sentence shall be deemed to constitute the act of all Limited
Partners and, in such event, each Limited Partner that does not execute such
written consent hereby agrees to be bound by the decision of those Limited
Partners executing such consent and hereby approves such action to the extent
such approval is required for such matter to be effective under the laws of such
jurisdiction. Prompt notice of the taking of action shall be given to Limited
Partners that have not consented in writing.

                                   ARTICLE XV

                               GENERAL PROVISIONS

         15.1 ADDRESSES AND NOTICES.

                  Any notice, demand, request, or report required or permitted
to be given or made to a Partner under this Agreement shall be in writing and
shall be deemed given or made (unless otherwise expressly provided herein): (i)
when delivered in person, by overnight mail using a nationally recognized
courier service at his address as shown on the records of the Partnership or by
facsimile transmission (with call-back confirmation) at the telefacsimile phone
number for such Partner shown on the records of the Partnership, or (ii) three
days after being placed in a United States Postal Service mailbox when sent by
United States registered or certified mail to the Partner at its address as
shown on the records of the Partnership, in any case regardless of any claim of
any Person who may have an interest in any Partnership Interest by reason of an
assignment or otherwise. If any notice or action is to be given or taken, as the
case may be, on a day that is not a Business Day, then such notice or action may
be given or taken, as the case may be, on the next Business Day.

                  This Agreement shall be binding upon and inure to the benefit
of the parties hereto and their heirs, executors, administrators, successors,
legal representatives, and permitted assigns. The failure of any parties hereto
to execute and deliver this Agreement shall not invalidate the Partnership
created by and among those parties executing and delivering this Agreement.

         15.6 INTEGRATION.

                  This Agreement constitutes the entire agreement among the
parties hereto pertaining to the subject matter hereof and supersedes all prior
agreements and understandings pertaining thereto.

         15.7 CREDITORS.

                  Subject to the provisions of Section 7.15 only, none of the
provisions of this Agreement shall be for the benefit of or enforceable by any
creditors of the Partnership or any other Person not a party to this Agreement.

         15.8 WAIVER.

                  No failure by any party to insist upon the strict performance
of any covenant, duty, agreement, or condition of this Agreement or to exercise

         15.10 APPLICABLE LAW.

         15.11 INVALIDITY OF PROVISIONS.

                  If any provision of this Agreement is declared or found to be
illegal, unenforceable, or void, in whole or in part, then the parties shall be
relieved of all obligations arising under such provision, but only to the extent
that it is illegal, unenforceable, or void, it being the intent and agreement of
the parties that this Agreement shall be deemed amended by modifying such
provision to the extent necessary to make it legal and enforceable while
preserving its intent or, if that is not possible, by substituting therefor
another provision that is legal and enforceable and achieves the same
objectives.

         15.12 CONFIDENTIALITY.

                  (a) The terms of this Agreement and information about the
Hotels and other, related assets and properties and operations of the
Partnership, its Controlled Entities and its non-Controlled Entities constitute
proprietary information and each of the Partners agrees to keep (and cause its
employees, agents, advisors, officers, directors, members and partners to keep)
all such information confidential. Proprietary information does not include,
however, information that is or becomes generally available to the public other
than as a result of a disclosure by a Partner or its employees, agents,
advisors, officers, directors, members and/or partners. If a Partner is
requested pursuant to, or required by, applicable law or regulation or by legal
process to disclose any proprietary information, prior to such disclosure by
such Partner (which disclosure, in such circumstances, will not constitute, or
be deemed to constitute, a breach of this Agreement), such Partner will provide
the Partnership and the other Partners with prompt notice of such request or
requirement in order to enable the Partnership to seek an appropriate protective
order or other remedy, to consult with such Partner with respect to taking steps
to resist or narrow the scope of such request or legal process, or to waive
compliance, in whole or in part, with the terms of this Section. In any such
event, such Partner will use its reasonable efforts to cause all proprietary
information that is so disclosed to be accorded confidential treatment. Without
prejudice to the rights and remedies otherwise available to the Partnership or
the Partners individually and collectively, each Partner agrees that the
Partnership and each other Partner shall be entitled to equitable relief by way
of injunction or otherwise if a Partner or any of its employees, agents,
advisors, officers, directors, members and/or partners breaches or threatens to
breach any of the provisions of this Section.

                  (b) Notwithstanding anything in this Section or the remainder
of the Agreement to the contrary (but subject to Article XI), each of the
Partnership and the Partners acknowledges that CGLH GP and/or CGLH LP may sell
or otherwise transfer all or a portion of its or their Partnership Interest(s)
to an investment fund or a party which may pool such interests with a number of
other equity positions and grant participations therein or issue one or more
classes of securities evidencing a beneficial interest in a rated or unrated
public offering or private placement (the "Securities"). One or more national
rating agencies may rate the investment fund or the Securities. In connection
therewith, each of the Partnership and the Partners agrees that CGLH LP and CGLH
GP may make available certain proprietary information to investment banking
firms, rating agencies, accounting firms, law firms and other third-party
advisory firms involved with the Securities or the investment fund(s). Such
proprietary information provided may ultimately be incorporated into the
offering documents for the Securities or investment fund(s) and thus such
information may be disclosed to various investors, purchasers and prospective
purchasers of the Securities or interests in the investment fund(s). All of the
aforesaid third-party advisors and professional firms shall be entitled to rely
on the information supplied by, or on behalf of, the Partnership. The
Partnership shall execute and deliver all such instruments, documents and other
papers, and do or cause to be done all such acts and things as CGLH LP and/or
CGLH GP may reasonably request in order to effect such sale, transfers,
participations and/or issuance of Securities. CGLH LP and/or CGLH GP shall pay
all of the Partnership's actual out-of-pocket expenses and third-party costs
(including attorneys' fees and expenses) associated therewith.

     has the effect of reducing, as a percentage of Total Voting Power, the
     Voting Power of Voting Securities Beneficially Owned by Investor (a
     "Dilutive Issuance"), the acquisition by the Investor of such number of
     Voting Securities as restore the Investor's Voting Power to the percentage

     Investor immediately prior to such Dilutive Issuance or (G) any or all
     outstanding shares of Class C Common Stock unless the acquisition of Class

     Investor no longer Beneficially Owns any such shares or Voting Securities
     or has any agreement or understanding relating to such shares, this Section
     2.1 shall be deemed to not have been violated; and provided, further, that
     no violation of this provision shall be deemed to have occurred by reason
     of the indirect acquisition of Beneficial Ownership of securities resulting
     from (x) investments in investment funds as to which no Investor or
     Affiliate thereof has Control or power to Control with respect to voting or

     of the Investor Designees in communicating (without public disclosure or

to Section 3.2).

     (b) Affiliates of Investor who (i) are not Related Transferees of any

Affiliates (other than (i) the Investor and (ii) Affiliates of the Investor to
the extent that such Affiliates are not also either the Lehman Parent Entities

provided, however that no such person will be deemed an Exempt Affiliate (x) if
any person involved in making the decision to enter into any transaction or take
any action that is prohibited during the Standstill Period was, at the time of
such decision, in possession of any material non-public Information provided to
Investor by the Company, its subsidiaries or representatives pursuant to Section
3.4 hereof or otherwise, (y) with respect to any action or transaction by such

or indirectly, assert active involvement in the day-to-day management or
operations of the Company, (ii) not, directly or indirectly, utilize any
corporate or business tradename of the Company (including, without limitation,
in press releases, publications or interviews); provided, however, that nothing

and customary actions to be taken by members of boards of directors of public
companies in carrying out the fiduciary duties that such directors owe to
shareholders of a public company, (2) such Persons from carrying out their

the Board of Directors at the request of the Future Major Investor, and (b) such
agreement, understanding or arrangement contains any terms with respect to the
matters covered by this Article 2 that are more favorable to the Future Major

                        Board Representation and Voting

     SECTION 3.1.  BOARD REPRESENTATION. (a) The Company agrees to the
provisions set forth in Section 3(b) of the Articles Supplementary relating to
the Series B Preferred Stock as if such provisions were included herein so long

earliest to occur of (A) such time that there are no shares of Class B Common
Stock outstanding, (B) such time that there are no shares of Class C Common

of Directors of the Company otherwise may be validly fixed by a resolution

Period, the Board of Directors shall consist of no more than eleven directors.

     During the Investor Designee Period, the Investor shall be entitled to
nominate Investor Designees who shall serve on one-half of the seats on each
committee of the Board of Directors other than any committee formed for the
purpose of considering matters relating to the Investor provided, however, that
if the Applicable Number is less than one-half of the number of seats on any
committee of the Board of Directors, then the Investor shall be entitled to
nominate Investor Designees only to the Applicable Number of seats on such
committee.

     (b) Immediately following the Closing, the Company will cause the five
persons designated by the Investor to be elected or appointed to the Board of
Directors to serve as the Series B Preferred Directors and as the Investor
Designees pursuant to this Agreement and shall take all action required to cause
the election or appointment to the Board of Directors of the Investor Designees
nominated by the Company, as contemplated by the next sentence. At all times
until the Investor and its Related Transferees both (i) no longer Beneficially
Own at least 5% of the Total Voting Power and (ii) no longer Beneficially Own
shares of Series B Preferred Stock and Notes which have an aggregate liquidation
preference or outstanding principal amount of at least 10% of the Original
Investment Amount (the "Investor Designee Period"), the Company agrees, subject
to Section 3.1(d), to support the nomination of, and the Company's Nominating
Committee shall recommend to the Board of Directors the inclusion in the slate
of nominees recommended by the Board of Directors to stockholders for election
as directors at each annual meeting of stockholders of the Company: (i) the
Applicable Number of Investor Designees (as defined in the next sentence) and
(ii) the number of other persons obtained by subtracting the Applicable Number
of Investor Designees from eleven, each of whom is (A) recommended by the
Nominating Committee and (B) not a partner, employee, director, officer,
Affiliate or associate (as defined in Rule 12b-2 under the Exchange Act) of
Investor or any Affiliate of Investor or as to which the Investor or its
Affiliates own at least ten percent of the voting equity securities
("Unaffiliated Directors"). The "Applicable Number" of Investor Designees shall
be (A) five Investor Designees so long as the Investor and Related Persons
Beneficially Own Voting Securities representing at least 30% or more of the
Total Voting Power (without taking into account any limitation on the conversion
of such Voting Securities in determining such Beneficial Ownership or the number
of shares issuable upon complete conversion) ("Shares"), (B) four Investor
Designees, so long as the Investor and Related Persons Beneficially Own at least
20% or more but less than 30% of the Shares, (C) three Investor Designees, so
long as the Investor and Related Persons Beneficially Own at least 10% or more
but less than 20% of the Shares, and (D) one Investor Designee, so long as the
Investor and Related Persons Beneficially Own at least 5% or more but less than
10% of the Shares (each a "Beneficial Ownership Threshold"). If, during the
Investor Designee Period, any vacancy (whether by death, retirement,
disqualification, removal from office or other cause, or by increase in number
of directors) occurs prior to a meeting of the Company's stockholders, the Board
(i) shall appoint, subject to Section 3.1(d), a person designated by the
Investor to fill a vacancy created by an Investor Designee ceasing to serve as a
director (except as a result of the reduction of the number of Investor
Designees entitled to be included on the Board of Directors by reason of a
decrease in the Investor's Beneficial Ownership of Shares below any Beneficial
Ownership Threshold), and (ii) may appoint a person who qualifies as an
Unaffiliated Director and is recommended by the Nominating Committee pursuant to
the procedures set forth in the following paragraph to fill a vacancy created by
an Unaffiliated Director ceasing to serve as a director (provided, however, that
in the case of a vacancy relating to an Unaffiliated Director, if a majority of
the Nominating Committee is unable to recommend a replacement, then the Board
seat with respect to this vacancy shall remain vacant), and each such person
shall be an Investor Designee or Unaffiliated Director, as the case may be, for
purposes of this Agreement.

     At all times during the Investor Designee Period, Unaffiliated Directors
shall be designated exclusively by a majority of a nominating committee (the
"Nominating Committee"), which shall at all times during the Investor Designee
Period consist of not more than four persons, two (or such lesser number of
Investor Designees as are then required to be included on the Board of
Directors) of whom shall be Investor Designees and the remainder of whom shall
be Unaffiliated Directors. If the Nominating Committee is unable to recommend
one or more persons to serve as Unaffiliated Directors (except with respect to
any vacancy created by an Unaffiliated Director ceasing to serve as such) for a
period of 180 days from the date the Nominating Committee first meets to
consider such recommendation, then upon, and only upon, the expiration of such
180-day period the Board of Directors may nominate and recommend for election by
stockholders one or more persons to serve as such Unaffiliated Directors.

     At all times during the Investor Designee Period, the Board of Directors
shall maintain in existence a "Compensation Committee" consisting of four
directors of which two (or such lesser number of Investor Designees as are then
required to be included on the Board of Directors) shall be Investor Designees.
The Compensation Committee shall have the exclusive responsibility of
administering the Company's stock option and incentive plans and of determining
the compensation of executive officers of the Company.

                                      -10-
<PAGE>   158

     The foregoing provisions shall be effected pursuant to an amendment to the
Company's Bylaws in a form reasonably acceptable to the parties to this
Agreement, which shall not be further amended by the Board of Directors during
the Investor Designee Period.

     (c) Upon any decrease in the Investor's Beneficial Ownership of Shares
below any Beneficial Ownership Threshold, the Investor shall cause a number of
Investor Designees to offer to immediately resign from the Company's Board of
Directors such that the number of Investor Designees serving on the Board of
Directors immediately thereafter will be equal to the number of Investor
Designees which the Investor would then be entitled to designate under Section
3.1(b). Upon termination of the Investor Designee Period, the Investor shall
promptly cause all of the Investor Designees to offer to resign immediately from
the Board of Directors and any committees thereof and the Company's obligations
under this Section 3.1 shall terminate.

     (d) Notwithstanding the provisions of this Section 3.1, the Investor shall
not be entitled to designate any person to the Company's Board of Directors (or
any committee thereof) in the event (i) that the Company receives a written
opinion of its outside counsel that an Investor Designee would not be qualified
under any applicable law, rule or regulation to serve as a director of the
Company, (ii) if the Company objects to an Investor Designee because such
Investor Designee has been involved in any of the events enumerated in Item 2(d)
or (e) of Schedule 13D or such person is currently the target of an
investigation by any governmental authority or agency relating to felonious
criminal activity or is subject to any order, decree, or judgment of any court
or agency prohibiting service as a director of any public company or providing
investment or financial advisory services or (iii) such Investor Designee is an
employee of a Lehman Parent Entity but is not an officer of such Lehman Parent
Entity and, in any such event, the Investor shall withdraw the designation of
such proposed Investor Designee and designate a replacement therefor (which
replacement Investor Designee shall also be subject to the requirements of this
Section). The Company shall use its reasonable best efforts to notify the
Investor of any objection to an Investor Designee sufficiently in advance of the
date on which proxy materials are mailed by the Company in connection with such
election of directors to enable the Investor to propose a replacement Investor
Designee in accordance with the terms of this Agreement.

     (e) Each Investor Designee serving on the Board of Directors shall be
entitled to all compensation and stock incentives granted to directors who are
not employees of the Company on the same terms provided to, and subject to the
same limitations applicable to, such directors.

     (f) The Company shall obtain and cause to be maintained in effect, with
financially sound insurers, a policy of directors' and officers' liability
insurance in an amount and upon such terms as, from time to time, are reasonably
and customary for a public company, after taking into account the size and
nature of business of the Company.

     (g) The Charter or Bylaws, or both, shall to the fullest extent permitted
by law provide for indemnification of, and advancement of expenses to, and
limitation of the personal liability of, the directors of the Company or such
other person or persons, if any, who, pursuant to a provision of such
Certificate of Incorporation, exercise or perform any of the powers or duties
otherwise conferred or imposed upon such directors, which provisions shall not
be amended, repealed or otherwise modified in any manner adverse to the
directors until at least six (6) years following the date that the Investor is
no longer entitled to designate directors pursuant to this Section 3.1.

     (h) The parties acknowledge that Affiliates of the Investor and Investor
Partners and their Affiliates have investments in other business similar to and
which may compete with the Company's businesses ("Competing Businesses") and
reserve the right to make additional investments in other Competing Businesses
independent of their investments in the Company. By virtue of the Investor
holding securities of the Company or by having persons designated by or
affiliated with such Investor serving on the Board or any Subsidiary's Board of
Directors (or the functional equivalent thereof in the case of non-corporate
Subsidiaries) or otherwise, neither the Investor nor any of the Investor's
Affiliates and Investor Partners and their Affiliates shall have any obligation
to the Company, or any Subsidiary to refrain from competing with the Company or
any Subsidiary, making investments in Competing Businesses, otherwise engaging
in any commercial activity, and the Company and its Subsidiaries hereby waive
any right which they otherwise would have with respect to any such investments
or activities undertaken by Investor and Investor Partners and their Affiliates,
provided that nothing herein will affect the Company's rights under Section 3.5.
Without limitation of the foregoing, the Investor or any of the Investor's
                                      -11-
<PAGE>   159

Affiliates and Investor Partners and their Affiliates may engage in or possess
an interest in other business ventures of any nature or description,
independently or with others, similar or dissimilar to the business of the
Company or any Subsidiary, and none of the Company, nor any Subsidiary shall
have any rights or expectancy by virtue of Investor's relationships with the
Company, any Subsidiary, this Agreement or otherwise in and to such independent
ventures or the income of profits derived therefrom; and the pursuit of any such
venture, even if such investment is in a Competing Business, shall not be deemed
wrongful or improper, provided that nothing herein will affect the Company's
rights under Section 3.5. Neither the Investor nor any of its Affiliates and
Investor Partners and their Affiliates shall be obligated to present any
particular investment opportunity to the Company or any Subsidiary even if such
opportunity is of a character that, if presented to the Company or a Subsidiary,
could be taken by the Company or such Subsidiary, and the Investor and its
Affiliates and Investor Partners and their Affiliates shall continue to have the
right to take for their own respective account or to recommend to others any
such particular investment opportunity.

     (i) The Company shall pay all reasonable travel expenses and other
out-of-pocket disbursements incurred by the directors to attend meetings of the
Board, of any Subsidiary board of directors or of any committees thereof in
accordance with the procedures from time to time in effect for Unaffiliated
Directors.

     SECTION 3.2.  VOTING. (a) Investor agrees that during the Standstill Period
Investor shall be present in person or represented by proxy, at all meetings of
stockholders of the Company so that all Conversion Shares Beneficially Owned by
Investor and entitled to vote at that meeting shall be counted for the purpose
of determining the presence of a quorum at such meetings. Investor agrees that
during the Standstill Period:

          (i) In connection with the election of directors of the Company,
     Investor shall vote or cause to be voted all Conversion Shares Beneficially
     Owned by such Investor to elect those individuals nominated in accordance
     with the provisions of Section 3.1.

          (ii) In connection with other proposals submitted to stockholders of
     the Company, Investor shall be free to vote or cause to be voted, or
     consent with respect to, all Voting Securities Beneficially Owned by such
     Investor in its discretion.

     SECTION 3.3.  REQUIRED BOARD APPROVAL. In addition to any other required
vote of the Board of Directors, the Company agrees that until the later of (i)
the expiration or termination of the Standstill Period, (ii) if the Standstill
Period is terminated by reason of the occurrence of any of the events specified
in Section 2.2(a) through (f) or Section 2.2(l), the fourth anniversary of the
Closing and (iii) such time as the Investor and its Affiliates no longer
Beneficially Own securities of the Company having an aggregate principal amount,
liquidation preference or Fair Market Value, as the case may be, of at least 51%
of the Original Investment Amount, each of the following actions also shall
require the affirmative vote of at least a majority of the Investor Designees:

     (a) except for any transaction or series of transactions involving only
wholly-owned subsidiaries of the Company, (i) consolidate or merge into or with
any other Person, or (ii) enter into any other Reorganization Transaction (or

amount (as to the Company and all of its subsidiaries), including without
limitation, any liabilities of the acquired entities, in excess of the Threshold
Amount;

     (e) make or commit to make capital expenditures which exceed the amount set
forth in the Budget by more than the Threshold Amount;

     (g) enter into or commit to enter into any joint ventures or any
partnerships, establish any non-wholly-owned subsidiaries or form any joint

     (h) sell, lease, transfer or otherwise dispose of any assets of the Company
or any of its subsidiaries in excess of the Threshold Amount;

Agreement, except, in either case, (i) for any conversion of the Notes or the
Series B Preferred Stock into Common Stock or any Disposition by the Investor
permitted by this Agreement, (ii) in connection with a transaction approved or
recommended by unanimous vote of the Board members present and voting thereon

then required to be included on the Board of Directors), and (iii) as reasonably
determined by the Board to be required by law or the requirements of a National
Securities Exchange;

     (k) pay, or set aside any sums for the payment of, any dividends, or make
any distribution on, any shares of its common stock or redeem, repurchase or
otherwise acquire any outstanding shares of its common stock or any other of its
outstanding securities (other than indebtedness at maturity in accordance with
the terms thereof);

     (l) issue, sell or amend the rights of any capital stock or other
securities of the Company or any of its subsidiaries except for (i) dividends or

shares of Common Stock; (ii) in connection with the issuance of Common Stock
upon conversion of the Notes or Series B Preferred Stock or otherwise in

advisors, consultants or outside directors of the Company directly or pursuant

     (m) change the Company's independent public accountants (unless the Audit

divestiture involving or expected (in the opinion of the Board) to involve,
gross proceeds in excess of the Threshold Amount or a public offering of
securities;

     (n) become a party to any agreement which by its terms restricts the
Company's performance of the terms of the Purchase Agreement, the Registration

(together, the "Documents");

     (o) grant any registration rights in respect of securities of the Company
which have an aggregate value, in any year ending on the anniversary of the date
of this Agreement, greater than the lesser of (i) the Threshold Amount and (ii)
5% of the market capitalization of the Company that would be inconsistent with
the rights granted to the holders of Registrable Securities under the
Registration Rights Agreement or otherwise conflict with or violate the
provisions thereof;

     (p) amend, modify or waive the Charter, the Notes or the Bylaws in any

"affiliate" or "associate" (as such terms are defined under Rule 12b-2 under the
Exchange Act) of the Company or any stockholder of the Company (other than the
Investor or its Affiliates).

     For the purposes of this section the term "Threshold Amount" shall mean,
(a) with respect to any individual transaction, action or instance, the amount
of $2,000,000 at any time prior to the first anniversary of the Closing, which
amount shall increase by $1,000,000 from the amount then in effect on each
anniversary of the Closing if the Company EBITDA (as defined below) is greater
than or equal to the EBITDA Target (as defined below) for such anniversary, (b)
provided that (i) if the Company EBITDA for such anniversary is less than the
EBITDA Target for such anniversary, the Threshold Amount shall be the increased
Threshold Amount that would otherwise apply pursuant to clause (a) above
multiplied by the Company EBITDA for such anniversary divided by the EBITDA
Target for such anniversary, and (ii) the Threshold Amount shall not exceed
$5,000,000, and further provided, however, that all such transactions subject to
this limitation shall not, in the aggregate for any year ending on an
anniversary of the Closing, exceed the lesser of (x) two times the amount

attributable to management agreements with respect to hotels owned directly or
indirectly by CGLH-IHC Fund I, L.P.

     The "EBITDA Target" shall mean the EBITDA of the Company for calendar year
2000 adjusted for the revenues and expenses, including minority interest,
affected by the Wyndham Redemption Agreement as though such agreement had been
in effect throughout the entire year, plus: (i) for the first anniversary of the
date of the Closing, $10,000,000; (ii) for the second anniversary of the date of
the Closing, $20,000,000; and (iii) for the third anniversary of the date of the
Closing, $30,000,000.

     SECTION 3.4  NOTICES OF DISPOSITIONS OF VOTING SECURITIES. Not later than
the tenth day following the end of any calendar month during the Standstill
Period in which one or more Dispositions of Voting Securities by Investor or any
of its Affiliates shall have occurred, Investor shall give written notice of all
such Dispositions by Investor, and shall use its reasonable best efforts to
cause its Affiliates to give written notice of all such Dispositions by its
Affiliates, to the Company unless any such Disposition has been reflected in a
public filing that was delivered to the Company on or in advance of the date
upon which notice thereof under this Section 3.4 would have been due. Such
notice shall state the date upon which each such Disposition was effected, the
number and type of Voting Securities involved in each such Disposition, the
means by which each such Disposition was effected and, to the extent known, the
identity of the Person acquiring Voting Securities.

     SECTION 3.5.  ACCESS TO INFORMATION. The Company will provide Investor
during normal business hours upon reasonable prior notice with (i) access to the
books and records of the Company and information relating to the Company, its
properties, operations, financial condition and affairs (together with the
reports specified in the following sentence, the "Information") and (ii) the
opportunity to consult with management of the Company, at least once each month,
regarding the Company, its properties, operations, finances and affairs, in the
case of each of clauses (i) and (ii), in accordance with and subject to the
limitations in Section 5.4 of the Purchase Agreement. The Company will provide
Investor, on a timely basis, with the financial and other information required
to be delivered to the Purchaser pursuant to Section 5.4 of the Purchase
Agreement. Certain of the parties who may hold partnership interests in Investor
may request the Information and consultation rights provided herein to enable
the securities held by such person to qualify as a "venture capital investment"
as to which such persons have "management rights," in each case as such terms
are defined in Department of Labor Regulation Section 2510.3-101(d) in which
event the Company shall provide such access; provided, however, that nothing
herein shall require the Company to furnish such person with more than rights of
access to Information and consultation provided herein regardless of whether
such rights are sufficient for such person to comply with venture capital
operating company requirements. In furtherance of the foregoing, and in addition
to the rights of Investor Designees under Section 3.3 for so long as the
Investor Beneficially Owns any of the Notes, shares of Series B Preferred Stock
or Conversion Shares, the Company agrees to inform the Investor in advance of
any corporate actions which the Company considers to be major or significant,
including, without limitation,

                                      -14-
<PAGE>   162

extraordinary dividends, mergers, acquisitions or dispositions of significant
assets, issuances of significant amounts of debt or equity, the signing,
acquisition or termination of any hotel management contract, and material
amendments to the Charter or Bylaws of the Company, and (subject to the
limitations specified in the proviso in the preceding sentence) to provide the
Investor with the opportunity to consult with management of the Company with
respect to such matters. The Investor and such other persons exercising rights
under this Section agree to hold in strict confidence all nonpublic Information
furnished to them and to use all Information only in connection with the
management of their investment in the Company, except that they may disclose any
information that (i) is or becomes generally available to the public other than
as a result of disclosure by them, and (ii) is or becomes available to them from
a source other than the Company; provided, however, that, to their knowledge,
the source is not bound by a confidentiality obligation with the Company in
respect thereof. If any person is required by a court or administrative agency
to disclose any of the nonpublic Information, such person shall promptly notify
the Company of such requirement so that the Company may at its own expense
oppose such requirement or seek a protective order and request confidential
treatment of such Information. It is agreed that if such person is nonetheless
compelled to disclose the Information, the Investor may disclose such portion of
the Information which is legally required without liability hereunder. In any
event, such person will not oppose action by the Company to obtain a protective
order or other reliable assurance that confidential treatment will be accorded
the Information. Nothing herein shall permit any such person to disclose
material non-public Information to permit such person to purchase or sell
securities of the Company in compliance with the federal securities laws. The
Investor hereby acknowledges that it is aware, and that such other persons, and
the officers, partners, directors, employees, representatives and agents of such
other persons and the Investor, have been, or will be prior to receiving
Information, advised by the Investor that applicable securities laws may
prohibit any person who has material, non-public information from purchasing or
selling securities of the Company or from communicating the information to any
other person or entity.

                                   ARTICLE 4

                             Transfer Restrictions

     SECTION 4.1.  RESTRICTIONS ON DISPOSITIONS. During the Standstill Period,
Investor shall not directly or indirectly, sell, assign, donate, transfer,
pledge, hypothecate, grant any option with respect to or otherwise dispose of
any interest in (or enter into an agreement or understanding with respect to the
foregoing) any Voting Securities acquired pursuant to the Purchase Agreement or
upon conversion of such securities (a "Disposition"), except as set forth below
in this Section 4.1.

     Dispositions may be effected by an Investor during the Standstill Period as
follows:

     (a) No Dispositions of any nature may be made prior to the date that is six
months after the Closing, except pursuant to Sections 4.1(e) and (f).

     (b) After six months after the Closing, Dispositions of Voting Securities
may be made at any time in compliance with the Registration Rights Agreement.

     (c) After six months after the Closing, Dispositions of Voting Securities
may be made pursuant to sales effected in accordance with Rule 144 under the
Securities Act; provided that such Dispositions shall not be made to any Person
who or which would immediately thereafter, to the knowledge of Investor, any of
its Affiliates, or Investor's broker, Beneficially Own Voting Securities
representing more than the Maximum Ownership.

     (d) After six months after the Closing, Dispositions may be made to any
Person (other than pursuant to a Reorganization Transaction) that would,
following such Disposition, Beneficially Own no more than the Maximum Ownership.

     (e) Dispositions may be made pursuant to a merger transaction or other
business combination or a tender offer for outstanding shares of Common Stock
which is recommended to the stockholders of the Company generally by at least a
majority of the entire Board of Directors.

     (f) Dispositions may be made by Investor to (i) any holder of partnership
or other ownership interests in Investor or (ii) any other Person (provided,
that, in respect of any such disposition to any other Person before the
                                      -15-
<PAGE>   163

second anniversary of the date hereof, the Company must consent in writing to
such disposition, such consent not to be unreasonably withheld) that, in either
case, executes an instrument in form and substance satisfactory to the Company
in which it makes the representations and warranties set forth in Section 1.3(b)
as of the date of the execution of such instrument and agrees to be bound by the
terms of this Agreement as if an original signatory to this Agreement (each such
transferee, a "Related Transferee"), in which case such Related Transferee shall
thereafter be an "Investor" for all purposes of this Agreement.

     (g) With respect to Voting Securities which are, by their terms,
convertible into or exercisable or exchangeable for other Voting Securities such
conversion, exercise or exchange shall not be deemed a Disposition. Without
limiting the foregoing, the Company acknowledges that the conversion of the Note
or shares of Series B Preferred Stock into Conversion Shares shall not be a
Disposition.

     As used herein, the term "Maximum Ownership" shall mean 20% of the Total
Voting Power in the case of a Person who is eligible to report such ownership on
Schedule 13G under the Exchange Act and 12.5% of the Total Voting Power in the
case of any other Person.

     SECTION 4.2.  RIGHTS AGREEMENT. The Company represents that it has amended
its Rights Agreement to permit the Dispositions permitted by this Agreement such
that the acquisition of the Maximum Ownership by any transferee shall not result
in such transferee becoming an Acquiring Person as defined in the Rights
Agreement. The Company agrees that it shall not adopt any amendment to the
Rights Agreement inconsistent with the foregoing.

     UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED, OR THE
     SECURITIES LAWS OF ANY STATE OF THE UNITED STATES. SUCH SHARES MAY NOT BE

     (c) The Company may enter a stop transfer order with the transfer agent or

     SECTION 5.3.  ENFORCEMENT. Investor, on the one hand, and the Company, on
the other hand, acknowledge and agree that irreparable injury to the other party
would occur in the event any of the provisions of this Agreement were not
performed in accordance with their specific terms or were otherwise breached and
that such injury would not be adequately compensable in damages. It is
accordingly agreed that, in addition to any other remedies which may be
available at law or in equity, each party hereto (the "Moving Party") shall be
entitled to specific enforcement of, and injunctive relief to prevent any

take action, directly or indirectly, in opposition to the Moving Party seeking
such relief on the grounds that any other remedy or relief is available at law

condition to the granting of any such relief.

as expressed in such invalid, illegal or unenforceable provision.

provision of this Agreement shall not operate as or be construed to be a waiver
of any other breach of such provision or of any breach of any other provision of
this Agreement. The failure of a party to insist upon strict adherence to any
term of this Agreement on one or more occasions shall not be considered a waiver
or deprive that party of the right thereafter to insist upon strict adherence to
that term or any other term of this Agreement.

party's prior written consent, except by the Investor to a Related Transferee as
expressly provided in this Agreement (and that nothing herein restricts the
transfer of any of the rights of Investor under the Registration Rights
Agreement in accordance the terms of the Registration Rights Agreement).

     SECTION 5.11.  FURTHER ASSURANCE. From time to time on and after the date
of this Agreement, the Company and Investor, as the case may be, shall deliver
or cause to be delivered to the other party hereto such further documents and
instruments and shall do and cause to be done such further acts as the other

Agreement, the Company and Investor each irrevocably consent to service of
process out of any of the aforementioned courts in any such action or proceeding
by the mailing of copies thereof by registered or certified mail, postage
prepaid, or by recognized international express carrier or delivery service, to
the Company or Investor at their respective addresses referred to in this
Agreement. The Company and Investor each hereby irrevocably waives any objection
which it may now or hereafter have to the laying of venue of any of the
aforesaid actions or proceedings arising out of or in connection with this
Agreement brought in the courts referred to above and hereby further irrevocably
waives and agrees, to the extent permitted by applicable law, not to plead or
claim in any such court that any such action or proceeding brought in any such
court has been brought in an inconvenient forum. Nothing in this Agreement shall
affect the right of any party hereto to serve process in any other manner
permitted by law.

     SECTION 5.13.  INVESTMENT BANKING SERVICES. Until the end of the Investor
Designee Period, if the Company seeks to retain an investment bank or similar
financial institution ("Financial Institution") other than one of the Lehman
Parent Entities, the Company shall deliver written notice of such intended
retention of another Financial Institution (the "Notice") to a Senior Vice
President of the Principal Transactions Group of Lehman Brothers Holdings Inc
("Lehman Brothers"), setting forth the identity of such other Financial
Institution, the nature of the engagement or Investment Banking Services sought
and offered, a description (including timing) of the contemplated
transaction(s), and the fees charged by, or payable to, such Financial
Institution. For a period of fifteen days after the date that Lehman Brothers
shall have received such notice, Lehman Brothers shall have the right to advise
the Company that Lehman Brothers will perform such Investment Banking Services
on the terms set forth in the notice; provided, however, that if the fees to be
paid such Financial Institution are less than the market rate fees charged for
the contemplated transaction, the fees payable to Lehman Brothers shall be the
"market rate fees." The Partners agree, for the purposes of this Agreement, that
listed on Exhibit A annexed hereto and made a part hereof are "market rate fees"
for certain transactions. If Lehman Brothers declines the engagement set forth
in the Notice, the Company may engage (i) the Financial Institution set forth in
the Notice on the terms set forth therein or (ii) such other Financial
Institution to provide the Investment Banking Services set forth in the Notice
in connection with the contemplated transaction(s) described therein for fees
not in excess of "market rate fees." Lehman Brothers shall be a third party
beneficiary of this Section and shall have the right to enforce the terms of
this Section to their fullest extent.

                         INTERSTATE HOTELS CORPORATION
                    DESIGNATING A SERIES OF PREFERRED STOCK
                                  AS SHARES OF
                      SERIES B CONVERTIBLE PREFERRED STOCK
                           (PAR VALUE $.01 PER SHARE)
                            ------------------------

     Interstate Hotels Corporation, a corporation organized and existing under
the laws of Maryland (the "Corporation"), does hereby certify to the State
Department of Assessments and Taxation of Maryland that:

     FIRST: Pursuant to the authority contained in the Charter of the
Corporation (the "Charter"), and in accordance with the provisions of Section
2-208 of the Maryland General Corporation Law, the Board of Directors of the
Corporation duly adopted a resolution on [                ], 2000 creating and
classifying a series of preferred stock, par value $.01 per share (the
"Preferred Stock"), designated as Series B Convertible Preferred Stock (the
"Series B Preferred Stock") with the preferences, conversion and other rights,
voting powers, restrictions, limitations as to dividends and other
distributions, qualifications and terms and conditions of redemption of shares
of Series B Preferred Stock as set forth below.

                      SERIES B CONVERTIBLE PREFERRED STOCK

     SECTION 1.  DESIGNATION AND AMOUNT; RANK.

     (a) Designation and Amount. The shares of such series shall be designated
as the "Series B Convertible Preferred Stock" and the number of shares
constituting such series shall be 850,000 shares of Series B Preferred Stock.
Section 9 contains the definitions of certain defined terms used herein.

     (b) Rank. The Series B Preferred Stock shall, with respect to dividend
distributions and distributions upon liquidation, winding-up and dissolution of
the Corporation, rank (i) senior (to the extent set forth herein) to all Junior
Stock; (ii) on a parity with Parity Stock; provided that any such stock that was
not approved by the holders in accordance with Section 3(d) shall be deemed to
be Junior Stock and not Parity Stock; and (iii) junior to all Senior Stock;
provided, that any such stock that was not approved by the holders in accordance
with Section 3(d) shall be deemed to be Junior Stock and not Senior Stock.

     SECTION 2.  DIVIDENDS AND DISTRIBUTIONS.

     (a) The holders of shares of Series B Preferred Stock shall be entitled to
receive on each Dividend Payment Date in respect of the Dividend Period ending
on such Dividend Payment Date (but without including such Dividend Payment
Date), commencing on the first Dividend Payment Date, cumulative dividends
payable in cash on each such Dividend Payment Date at a rate per annum equal to
8.75% of the Stated Amount of each share of the then outstanding Series B
Preferred Stock. Up to 25% of the cumulative dividends payable on each Dividend
Payment Date may be paid in additional shares of Series B Preferred Stock. If
dividends on the Series B Preferred Stock are in arrears and unpaid for a period
of 60 days or more, then an additional amount of dividends shall accrue at a
rate per annum, equal to 2.00% of the Stated Amount of each share of the then
outstanding Series B Preferred Stock from the last Dividend Payment Date on
which cash dividends were to be paid in full until such time as all dividends in
arrears have been paid in full, such additional dividends to be cumulative and
payable in shares of Series B Preferred Stock (including fractional shares) at
the Stated Amount. Any reference herein to "cumulative dividends" or "accrued
dividends" or similar phrases means that such dividends are fully cumulative and
accumulate and accrue on a daily basis (computed on the basis of a 360-day year
of twelve 30-day months) and compound quarterly on the Dividend Payment Dates at
the rate indicated above and in the manner set forth herein, whether or not they
have been declared and whether or not there are profits, surplus or other funds
of the Corporation legally available for the payment of dividends. All dividends
payable in additional
<PAGE>   171

shares of Series B Preferred Stock shall be paid through the issuance of
additional shares of Series B Preferred Stock (including fractional shares) at
the Stated Amount.

     (b) In case the Corporation shall at any time or from time to time declare,
order, pay or make a dividend or other distribution (including, without
limitation, any distribution of stock or other securities or property or rights
or warrants to subscribe for securities of the Corporation or any of its
Subsidiaries by way of dividend or spin off on the Common Stock), other than any
dividend or distribution of shares of Common Stock covered by Section 7(b)(i) or
any issuance of rights pursuant to the Rights Plan, as it may be amended from
time to time, then, and in each such case (a "Triggering Distribution"), the
holders of shares of Series B Preferred Stock shall be entitled to receive from
the Corporation, with respect to each share of Series B Preferred Stock held, in
addition to the dividends payable under Section 2(a), the same dividend or
distribution received by a holder of the number of shares of Common Stock into
which such share of Series B Preferred Stock is convertible on the record date
for such dividend or distribution, after giving effect to the contemporaneous
issuance of any additional shares of Series B Preferred Stock as described in
Section 2(a) above with respect to Accrued Dividends. Any such dividend or
distribution shall be declared, ordered, paid or made on the Series B Preferred
Stock at the same time such dividend or distribution is declared, ordered, paid
or made on the Common Stock and shall be in addition to any dividends payable
under Section 2(a).

     (c) (ii) No dividends shall be authorized by the Board of Directors or paid
or Set Apart for Payment by the Corporation on any Parity Stock for any period
unless the Accrued Dividends have been or contemporaneously are authorized and
declared and paid in full, or declared and, if payable in cash, a sum in cash
Set Apart for Payment, on the Series B Preferred Stock for all Dividend Periods
terminating on or prior to the date of payment of such dividends on such Parity
Stock. If any dividends are not so paid, all dividends declared upon shares of
the Series B Preferred Stock and any other Parity Stock shall be declared pro
rata so that the amount of dividends declared per share on the Series B
Preferred Stock and such Parity Stock shall in all cases bear to each other the
same ratio that the Accrued Dividends per share on the Series B Preferred Stock
and the accrued dividends on such Parity Stock bear to each other.

          (ii) So long as any share of the Series B Preferred Stock is
     outstanding, the Corporation shall not declare, pay or Set Apart for
     Payment any dividend on any of the Junior Stock (other than dividends in
     Junior Stock to the holders of Junior Stock), or make any payment on
     account of, or Set Apart for Payment money for a sinking or other similar
     fund for, the purchase, redemption or other retirement of, any of the
     Junior Stock or any warrants, rights, calls or options exercisable for or
     convertible into any of the Junior Stock whether in cash, obligations or
     shares of the Corporation or other property (other than in exchange for
     Junior Stock), and shall not permit any corporation or other entity
     directly or indirectly controlled by the Corporation to purchase or redeem
     any of the Junior Stock or any such warrants, rights, calls or options
     (other than in exchange for Junior Stock) unless the Accrued Dividends on
     the Series B Preferred Stock for all Dividend Periods ended on or prior to
     the date of such payment in respect of Junior Stock have been or
     contemporaneously are paid in full.

          (iii) So long as any share of the Series B Preferred Stock is
     outstanding, the Corporation shall not (except with respect to dividends as
     permitted by Section 2(c)(i)) make any payment on account of, or Set Apart
     for Payment money for a sinking or other similar fund for, the purchase,
     redemption or other retirement of, any of the Parity Stock or any warrants,
     rights, calls or options exercisable for or convertible into any of the
     Parity Stock, and shall not permit any corporation or other entity directly
     or indirectly controlled by the Corporation to purchase or redeem any of
     the Parity Stock or any such warrants, rights, calls or options unless the
     Accrued Dividends on the Series B Preferred Stock for all Dividend Periods
     ended on or prior to the date of such payment in respect of Parity Stock
     have been or contemporaneously are paid in full.

     SECTION 3.  VOTING RIGHTS.

     (a) Other than as expressly set forth herein, the Series B Preferred Stock
shall have no voting rights.

     (b) Except in the case of a Payment Default (in which case the Board of
Directors of the Corporation shall consist of thirteen directors), after both
(i) the earliest to occur of (A) such time that there are no shares of

                                       -1-
<PAGE>   172

Class B Common Stock outstanding, (B) such time that there are no shares of
Class C Common Stock outstanding, (C) September 30, 2003, and (D) such other
time as the number of Directors of the Corporation otherwise may be validly
fixed by a resolution adopted by the Board of Directors and (ii) the end of the
Investor Designee Period, the Board of Directors shall consist of no more than
eleven directors. During the Investor Designee Period, the holders of Series B
Preferred Stock shall have, in addition to the other voting rights set forth
herein, the exclusive right, voting separately as a single class, (i) prior to a
Payment Default, to elect the Applicable Number of directors of the Corporation
(as defined in the next sentence), (the "Series B Preferred Directors") and (ii)
after an occurrence of a Payment Default, to elect seven directors (which number
shall include the Series B Preferred Directors) such that the directors elected
by the holders of Series B Preferred Stock constitute a majority of the maximum
number of directors of the Board of Directors of the Corporation (such
additional directors elected during a Payment Default being referred to as, the
"Default Series B Preferred Directors"). The "Applicable Number" of directors
shall be (A) five directors so long as the Investor and Related Persons
Beneficially Own Voting Securities representing at least 30% or more of the
Total Voting Power (without taking into account any limitation on the conversion
of such Voting Securities in determining such Beneficial Ownership or the number
of shares issuable upon complete conversion) ("Shares"), (B) four directors, so
long as the Investor and Related Persons beneficially own at least 20% or more
but less than 30% of the Shares, (C) three directors, so long as the Investor
and Related Persons Beneficially Own at least 10% or more but less than 20% of
the Shares, and (D) one director, so long as the Investor and Related Persons
Beneficially Own at least 5% or more but less than 10% of the Shares. The right
of the holders of Series B Preferred Stock to vote for the election of directors
may be exercised at any annual meeting or at any special meeting called for such
purpose or at any adjournment thereof, or by the written consent, delivered to
the Secretary of the Corporation, of the holders of a majority of all shares of
Series B Preferred Stock outstanding as of the record date of such written
consent.

     (c) (i) With respect to the Series B Preferred Directors, immediately after
the date of the Issuance Date, and (ii) with respect to the Default Series B
Preferred Directors, immediately after such Payment Default has occurred, the
Board of Directors of the Corporation shall call for a special meeting or
written consent of the holders of shares of Series B Preferred Stock to elect
the Series B Preferred Directors or Default Series B Preferred Directors, as the
case may be. If the Corporation fails to send a notice, the meeting may be
called by any such holder. Each director, and any subsequent director elected
pursuant to this paragraph, shall serve as a director until his successor is
elected and qualified. In the event of a vacancy in respect of any directorship
elected by the holders of shares of Series B Preferred Stock pursuant to this
clause (c), the Corporation agrees to call a special meeting of the holders of
shares of Series B Preferred Stock at the request of the majority of the holders
of outstanding Series B Preferred Stock, in order that the holders of the Series
B Preferred Stock may elect a successor director, and at which meeting the
holders of Series B Preferred Stock shall be entitled to the same voting rights
as provided in the second sentence of the prior paragraph. The voting rights
with respect to the Default Series B Preferred Directors will terminate at such
time as all cumulative dividends in respect of all previously completed full
Dividend Periods that are in arrears on the Series B Preferred Stock have been
paid regularly for at least one year. Simultaneously with the termination of
such voting rights, the terms of office of the Default Series B Preferred
Directors (but not the Series B Preferred Directors) shall terminate; and the
remaining directors shall constitute the directors of the Corporation and the
size of the Board of Directors shall be reduced to nine. The holders of the
Series B Preferred Stock will continue to be entitled to vote for the Series B
Preferred Directors after a Payment Default has been cured.

     (d) For so long as both (x) any share of Series B Preferred Stock is
outstanding and (y) the later of (i) the expiration or termination of the
Standstill Period (as such term is defined in the Investor Agreement), (ii) if
the Standstill Period is terminated by reason of the occurrence of any of the
events specified in Section 2.2(a) through (f) or Section 2.2(l) of the Investor
Agreement, the fourth anniversary of the Closing and (iii) such time as the
Investor and its Affiliates no longer Beneficially Own securities of the
Corporation having an aggregate principal amount, liquidation preference or Fair
Market Value, as the case may be, of at least 51% of the Original Investment
Amount, the Corporation shall not, nor shall it permit any of its Subsidiaries
to, without first obtaining the written consent or approval of at least the
Requisite Holders:

          (i) voluntarily liquidate, dissolve or wind up;

                                       -2-
<PAGE>   173

          (ii) purchase, acquire or obtain any capital stock or other
     proprietary interest, directly or indirectly, in any other entity, except
     for (i) any transaction or series of transactions involving only
     wholly-owned subsidiaries of the Corporation as of the date hereof, or (ii)
     the purchase of all or substantially all of the capital stock or other
     proprietary interest of other entities for an aggregate purchase price,
     including without limitation, any liabilities of the acquired entities, of
     less than the Threshold Amount;

          (iii) purchase, acquire or obtain assets of any third party in an
     aggregate amount (as to the Corporation and all of its subsidiaries),
     including without limitation, any liabilities of the acquired entities, in
     excess of the Threshold Amount;

          (iv) make or commit to make capital expenditures which exceed the
     amount set forth in a budget approved by the Board of Directors by more
     than the Threshold Amount;

          (v) sell, transfer or otherwise dispose of any equity interest of the
     Corporation or any of its subsidiaries, except for transactions involving
     only wholly-owned subsidiaries of the Corporation which either (i) is in
     excess of the Threshold Amount, or (ii) relates to the Venture Fund;

          (vi) enter into or commit to enter into any joint ventures or any
     partnerships, establish any non-wholly-owned subsidiaries or form any joint
     venture (other than the Venture Fund) either (i) in excess of the Threshold
     Amount, or (ii) in activity or business competitive with the Venture Fund;

          (vii) sell, lease, transfer or otherwise dispose of any assets of the
     Corporation or any of its subsidiaries in excess of the Threshold Amount;

          (viii) create, incur, assume or suffer to exist any indebtedness for
     borrowed money (including any capital leases) of the Corporation or any of
     its subsidiaries at any one time outstanding in excess of the Threshold
     Amount;

          (ix) redeem the Rights issued pursuant to the Rights Plan or any
     successor agreement thereto or otherwise render the Rights Plan
     inapplicable to any person who would otherwise be an "Acquiring Person" as
     defined in the Rights Plan, except, in either case, (i) for any conversion

     under this Section 3(d);

          (xii) change the Corporation's independent public accountants (unless

     relating to compensation of executive officers as determined by the
     Compensation Committee of the Board of Directors) with any Affiliate or
     Associate of the Corporation or any stockholder of the Corporation (other
     than the Investor or its Affiliates).

     For the purposes of this section the term "Threshold Amount" shall mean,
(a) with respect to any individual transaction, action or instance, the amount
of $2,000,000 at any time prior to the first anniversary of the Closing, which
amount shall increase by $1,000,000 from the amount then in effect on each
anniversary of the Closing if the Corporation EBITDA (as defined below) is
greater than or equal to the EBITDA Target (as defined below) for such
anniversary, (b) provided that (i) if the Corporation EBITDA for such
anniversary is less than the EBITDA Target for such anniversary, the Threshold
Amount shall be the increased Threshold Amount that would otherwise apply
pursuant to clause (a) above multiplied by the Corporation EBITDA for such
anniversary divided by the EBITDA Target for such anniversary, and (ii) the
Threshold Amount shall not exceed $5,000,000, and further provided, however,
that all such transactions subject to this limitation shall not, in the
aggregate for any year ending on an anniversary of the Closing, exceed the
lesser of (x) two times the amount applicable to any individual transaction,

     restricts the Corporation's performance of the terms of the Purchase
     Agreement, the Registration Rights Agreement, the Notes, the Series B

     anniversary of the date of the Investor Agreement, greater than the lesser
     of (i) the Threshold Amount and (ii) 5% of the market capitalization of the
     Corporation that would be

                                       -4-

     liquidation preference, from the holders of Series B Preferred Stock
     (ratably amongst such holders) such portion of the outstanding Series B
     Preferred Stock as such securities redeemed, purchased or otherwise
     acquired for consideration (on an as-converted basis) bear to the total of
     the then-outstanding securities of the Corporation (on an as-converted
     basis).

     SECTION 4.  REDEMPTION

     (a) The Corporation shall, on the seventh anniversary of the Issuance Date
and subject to applicable law, redeem (the "Mandatory Redemption") all remaining
issued and outstanding shares of Series B Preferred Stock, at a price per share
in cash equal to the Stated Amount thereof together with all Accrued Dividends
thereon to the date of redemption. The Corporation shall not be required to
provide written notice to holders of Series B Preferred Stock of the Mandatory
Redemption, and the redemption date with respect to the Mandatory Redemption
shall be the seventh anniversary of the Issuance Date. The holders shall be
permitted to convert their Series B Preferred Stock at any time prior to the
redemption date.

     (b) In the event there occurs a Change in Control, the Corporation shall
offer to purchase from each holder all of the Series B Preferred Stock held by
such holder for an amount in cash equal to the greater of (i) the Liquidation
Preference of the shares of Series B Preferred Stock held by the holder, and
(ii) the Fair Market Value (as defined below) of the cash, securities and other
property that such holder of the Series B Preferred Stock would have received
had it converted its Series B Preferred Stock (including for such purposes any
shares of Series B Preferred Stock issuable in respect of Accrued Dividends)
into shares of Common Stock immediately prior to such Change in Control, plus
Accrued Dividends payable in cash to the extent not otherwise reflected pursuant
to the parenthetical phrase of this clause (ii) (the greater of (i) and (ii)
above being referred to as the "Change in Control Redemption Price"), in each
case by delivery of a notice in accordance with Section 4(c). In the event of a
Change in Control, each holder of Series B Preferred Stock shall have the right
(but not the obligation) to require the Corporation to purchase any or all of
the Series B Preferred Stock held by such holder for an amount in cash equal to
the Change in Control Redemption Price. Each holder of Series B Preferred Stock
shall also be permitted, until 20 Business Days following the date of the
mailing to it of the Corporation's notice described in Section 4(c)(i), to
convert all, and not less than all, of the shares of Series B Preferred Stock
held by such holder (including shares of Series B Preferred Stock issuable to
such holder as Accrued Dividends that have accelerated or will accelerate as a
result of a Change in Control) pursuant to Section 7 below; provided that any
shares of Common Stock issuable upon conversion of any Series B Preferred Stock
converted pursuant to this sentence after a Change in Control has occurred shall
be entitled to receive the same amount of cash, securities and other property in
connection with such Change in Control as the Common Stock outstanding prior to
the Change in Control. In the event a holder of Series B Preferred Stock does
not elect to have all of its shares of Series B Preferred Stock either (i)
redeemed by the Corporation pursuant to Section 4 or (ii) converted pursuant to
Section 7 below, in each case in connection with a specific Change in Control
event, then no dividends shall be deemed to have been accelerated in connection
with such Change in Control. In the event that any holder does not elect to
convert or redeem such holder's shares of Series B Preferred Stock pursuant to
the foregoing sentence, such holder shall retain any rights it has to convert or
redeem its shares of Series B Preferred Stock in connection with any subsequent
Change in Control. "Fair Market Value" with respect to any securities shall be
the Current Market Price thereof as of the close of business on the date of
measurement. The Fair Market Value of any asset other than cash and securities
shall be determined jointly and in good faith by the Corporation and the
Requisite Stockholders. In the event any dispute between the Corporation and the
Requisite Stockholders as to the Fair Market Value or Current Market Price
(which dispute remains unresolved for 10 Business Days), such dispute

                                       -5-
<PAGE>   176

shall be submitted for final determination to a mutually acceptable Investment
Banking Firm of national reputation familiar with the valuation of companies in
the hospitality and lodging industry ("Investment Banking Firm"). In the event
that the Corporation and the Requisite Stockholders cannot agree on a mutually
acceptable Investment Banking Firm within 10 Business Days, the Corporation, on
the one hand, and the Requisite Stockholders, on the other hand, shall each
select one Investment Banking Firm which two Investment Banking Firms shall
jointly make such determination within 20 business days after the date of such
event, or, if such two Investment Banking Firms are unable to agree on such
determination, the two Investment Banking Firms shall, by the end of the 20(th)
business day after the date of such event, select a third Investment Banking
Firm and notify such third Investment Banking Firm in writing (with a copy to
the Corporation and the holders of Series B Preferred Stock) of their respective
determinations of the Fair Market Value or Current Market Price following which
such third Investment Banking Firm shall, within 15 business days after the date
of its selection, notify the Corporation and the holders of Series B Preferred
Stock in writing of its selection of one or the other of the two original
determinations of the Fair Market Value or Current Market Price, which
determination shall be final and binding on the Corporation and the holders. The
fees and expenses of any such determination shall be borne by the Corporation.

     (c) (i) Within five Business Days following an event giving a holder of
shares of Series B Preferred Stock the right, pursuant to Section 4(b), to
require the Corporation to redeem all of such shares, the Corporation shall give
notice by mail to each holder of Series B Preferred Stock, at such holder's
address as it appears on the transfer books of the Corporation, of such event,
which notice shall set forth each holder's right to convert all, and not less
than all, of the shares of Series B Preferred Stock held by such holder, or to
require the Corporation to redeem all, but not less than all, shares of Series B
Preferred Stock held by it which are eligible for redemption pursuant to the
terms of Section 4(b), the redemption date (which date shall be no more than 30
Business Days following the date of such mailed notice), and the procedures to
be followed by such holder in exercising its right to cause such redemption or
effect such conversion. In the event a record holder of shares of Series B
Preferred Stock shall elect to require the Corporation to redeem all such shares
of Series B Preferred Stock pursuant to Section 4(b), such holder shall deliver
within 20 Business Days of the mailing to it of the Corporation's notice
described in this Section 4(c)(i), a written notice to the Corporation so
stating, specifying the number of shares to be redeemed pursuant to Section
4(b). The Corporation shall, in accordance with the terms hereof, redeem the
number of shares so specified on the date fixed for redemption. Failure of the
Corporation to give any notice required by this Section 4(c)(i), or the formal
insufficiency of any such notice, shall not prejudice the rights of any holders
of shares of Series B Preferred Stock to cause the Corporation to redeem or to
convert all such shares held by them. Notwithstanding the foregoing, the Board
of Directors of the Corporation may modify any offer pursuant to this Section
4(c)(i) to the extent necessary to comply with the Exchange Act and the rules
and regulations thereunder.

          (ii) The Corporation shall publish the fact that it is redeeming, or
     offering to redeem, shares of Series B Preferred Stock through a nationally
     prominent newswire service on or before the date of mailing any notice of
     redemption or right of redemption. At any time after a notice of redemption
     shall have been mailed and before such date of redemption the Corporation
     may deposit for the benefit of the holders of the Series B Preferred Stock
     called for redemption the funds necessary for such redemption with a bank
     or trust company doing business in the Borough of Manhattan, the City of
     New York, and having a capital and surplus of at least $1,000,000,000. Any
     interest allowed on moneys so deposited shall be paid to the Corporation.
     Upon the deposit of such funds or, if no such deposit is made, upon the
     date fixed for redemption (unless the Corporation shall default in making
     payment of the appropriate redemption amount), whether or not certificates
     for shares so called for redemption have been surrendered for cancellation,
     the shares of Series B Preferred Stock to be redeemed shall be deemed to be
     no longer outstanding and the holders thereof shall cease to be
     stockholders with respect to such shares and shall have no rights with
     respect thereto, except for the rights to receive the amount payable upon
     redemption, but without interest, and, up to the close of business on the
     date immediately preceding the date fixed for such redemption, the right to
     convert such shares pursuant to Section 7 hereof. Such deposit in trust
     shall be irrevocable except that any funds deposited by the Corporation
     which shall not be required for the redemption for which they were
     deposited because of the exercise of conversion rights shall be returned to
     the Corporation forthwith, and any funds deposited by the Corporation which
     are unclaimed at the end of one year from the date fixed for such
     redemption shall be
                                       -6-
<PAGE>   177

     paid over to the Corporation upon its request, and upon such repayment the
     holders of the shares of Series B Preferred Stock so called for redemption
     shall look only to the Corporation for payment of the appropriate amount.
     Any such unclaimed amounts paid over to the Corporation shall, for a period
     of six years from the date fixed for such redemption, be set apart and held
     by the corporation in trust for the benefit of the holders of such shares
     of Series B Preferred Stock, but no such holder shall be entitled to
     interest thereon. At the expiration of such six-year period, all right,
     title, interest and claim of such holders in or to such unclaimed amounts
     shall be extinguished, terminated and discharged, and such unclaimed
     amounts shall become part of the general funds of the Corporation free of
     any claim of such holders.

     SECTION 5.  REACQUIRED SHARES. Any shares of Series B Preferred Stock
converted, redeemed, purchased or otherwise acquired by the Corporation in any
manner whatsoever shall be retired and canceled promptly after the acquisition
thereof, and, if necessary to provide for the lawful redemption or purchase of
such shares, the capital represented by such shares shall be reduced in
accordance with the Maryland General Corporation Law. All such shares shall upon
their cancellation become authorized but unissued shares of Preferred Stock, par
value $.01 per share, of the Corporation and may be reissued as part of another
series of Preferred Stock, par value $.01 per share, of the Corporation subject
to the conditions or restrictions on authorizing, creating or issuing any class
or series, or any shares of any class or series, set forth in Section 3(d).

     SECTION 6.  LIQUIDATION, DISSOLUTION OR WINDING-UP. If the Corporation
shall adopt a plan of liquidation or of dissolution, or commence a voluntary
case under the Federal bankruptcy laws or any other applicable state or Federal
bankruptcy, insolvency or similar law, or consent to the entry of an order for
relief in any involuntary case under any such law or to the appointment of a
receiver, liquidator, assignee, custodian, trustee or sequestrator (or similar
official) of the Corporation or of any substantial part of its property, or make
an assignment for the benefit of its creditors, or admit in writing its
inability to pay its debts generally as they become due, or if a decree or order
for relief in respect of the Corporation shall be entered by a court having
jurisdiction in the premises in an involuntary case under the Federal bankruptcy
laws or any other applicable Federal or state bankruptcy, insolvency or similar
law, or appointing a receiver, liquidator, assignee, custodian, trustee,
sequestrator (or other similar official) of the Corporation or of any
substantial part of its property, or ordering the winding-up or liquidation of
its affairs, and any such decree or order shall be unstayed and in effect for a
period of 90 consecutive days and on account of such event the Corporation shall
liquidate, dissolve or wind up, or upon any other liquidation, dissolution or
winding-up of the Corporation (a "Liquidation"), the holders shall be entitled
to receive the greatest of (i) the Liquidation Preference of the shares of
Series B Preferred Stock held by the holder, and (ii) the Fair Market Value of
the cash, securities and other property that such holder of the Series B
Preferred Stock would have received had they converted their Series B Preferred
Stock (including for such purposes any shares of Series B Preferred Stock
issuable in respect of Accrued Dividends) into shares of Common Stock
immediately prior to such Liquidation, plus Accrued Dividends payable in cash to
the extent not otherwise reflected pursuant to the parenthetical phrase of this
clause (ii) (including for such purposes any shares of Series B Preferred Stock
issuable in respect of Accrued Dividends through the date of the Liquidation),
before any distribution shall be made or any assets distributed in respect of
Junior Stock to the holders of any Junior Stock including, without limitation,
Common Stock of the Corporation. After payment of the full amount of the
greatest of the amounts set forth in clause (i) or (ii) above to which they are
entitled, the holders of shares of Series B Preferred Stock will not be entitled
to any further participation in any distribution of assets of the Corporation.
For the purposes of this Section 6 the voluntary sale, conveyance, exchange or
transfer of all or substantially all of the property or assets of the
Corporation or the consolidation or merger of the Corporation with or into one
or more other corporations shall not be deemed to be a liquidation, winding-up
or dissolution of the Corporation.

     SECTION 7.  CONVERSION INTO COMMON STOCK. Each share of Series B Preferred
Stock, including any shares of Series B Preferred Stock issued as Accrued
Dividends (including Accrued Dividends that have been accelerated in connection
with a Change in Control and assuming any shares of Common Stock into which such
shares are converted will be treated in all respects as shares of Common Stock
outstanding prior to the Change in Control), may, subject to the provisions of
paragraph (h) below, at the option of the holder thereof, be converted into
shares of Common Stock at any time, whether or not the Corporation has given
notice of redemption under Section 4, on the terms and conditions set forth in
this Section 7.

                                       -7-
<PAGE>   178

     (a) Subject to the provisions for adjustment hereinafter set forth, each
share of Series B Preferred Stock shall be convertible in the manner hereinafter
set forth into a number of fully paid and nonassessable shares of Common Stock
equal to the product obtained by multiplying the Applicable Conversion Rate (as
defined below) by the number of shares of Series B Preferred Stock being
converted. The "Applicable Conversion Rate" means the quotient obtained by
dividing the Conversion Value on the date of conversion by the Conversion Price
as adjusted pursuant to Section 7(b) on the date of conversion.

     (b) The Conversion Price shall be subject to adjustment from time to time
as follows:

          (i) In case the Corporation shall at any time or from time to time
     after the original issuance of the Series B Preferred Stock declare a
     dividend, or make a distribution, on the outstanding shares of Common Stock
     in either case, in shares of Common Stock, or effect a subdivision,
     combination, consolidation or reclassification of the outstanding shares of
     Common Stock into a greater or lesser number of shares of Common Stock,
     then, and in each such case, the Conversion Price in effect immediately
     prior to such event or the record date therefor, whichever is earlier,
     shall be adjusted by multiplying such Conversion Price by a fraction, the
     numerator of which is the number of shares of Common Stock that were
     outstanding immediately prior to such event and the denominator of which is
     the number of shares of Common Stock outstanding immediately after such
     event. An adjustment made pursuant to this Section 7(b)(i) shall become
     effective (x) in the case of any such dividend or distribution, immediately
     after the close of business on the record date for the determination of
     holders of shares of Common Stock entitled to receive such dividend or
     distribution, or (y) in the case of any such subdivision, reclassification,
     consolidation or combination, at the close of business on the day upon
     which such corporate action becomes effective.

          (ii) In case the Corporation shall issue (other than upon the exercise
     of options, rights or convertible securities) shares of Common Stock (or
     options, rights, warrants or other securities convertible into or
     exchangeable for shares of Common Stock) at a price per share (or having an
     exercise or conversion price per share) less than the Current Market Price
     as of the Business Day immediately preceding the Measurement Date, other
     than (x) in a transaction to which Section 2(a), 2(b) or 7(b)(i) applies,
     (y) pursuant to options or other securities under any employee or director
     benefit plan or program of the Corporation approved by the Board of
     Directors of the Corporation or shares of Common Stock issued upon the
     exercise thereof, (z) pursuant to the conversion of the Series B Preferred
     Stock or the Class B Common Stock or Class C Common Stock (the issuances
     under clauses (x), (y) and (z) being referred to as "Excluded Issuances"),
     then, and in each such case, the Conversion Price in effect immediately
     prior to the Measurement Date shall be reduced so as to be equal to an
     amount determined by multiplying such Conversion Price by a fraction of
     which the numerator shall be the number of shares of Common Stock of all
     classes outstanding at the close of business on the Measurement Date plus
     the number of shares of Common Stock (or the number of shares of Common
     Stock issuable upon the conversion, exchange or exercise of such options,
     rights, warrants or other securities convertible into or exchangeable for
     shares of Common Stock) which the aggregate consideration receivable by the
     Corporation in connection with such issuance would purchase at such Current
     Market Price and the denominator shall be the number of shares of Common
     Stock of all classes outstanding at the close of business on the
     Measurement Date plus the number of shares of Common Stock (or the number
     of shares of Common Stock issuable upon the conversion, exchange or
     exercise of such options, rights, warrants or other securities convertible
     into or exchangeable for shares of Common Stock) so issued. For purposes of
     this Section 7(b)(ii), the aggregate consideration receivable by the
     Corporation in connection with the issuance of shares of Common Stock or of
     options, rights, warrants or other convertible securities shall be deemed
     to be equal to the sum of the gross offering price (before deduction of
     customary underwriting discounts or commissions and expenses payable to
     third parties) of all such securities plus the minimum aggregate amount, if
     any, payable upon conversion or exercise of any such options, rights,
     warrants or other convertible securities into shares of Common Stock, less
     any original issue discount, premiums and other similar incentives which
     have the effect of reducing the effective price per share. For purposes of
     this Section 7(b)(ii), such adjustment shall become effective immediately
     prior to the opening of business on the Business Day immediately following
     the Measurement Date.

                                       -8-
<PAGE>   179

          (iii) In the event the Purchaser (as such term is defined in the
     Securities Purchase Agreement) exercises its option, pursuant to Section
     10.2(b) of the Securities Purchase Agreement, to decrease the Conversion
     Price of its shares of Series B Preferred Stock, the Conversion Price of
     such shares shall be decreased in the manner and to the extent set forth in
     Section 10.2(b) of the Securities Purchase Agreement.

          (iv) No adjustment in the Conversion Price shall be required unless
     such adjustment would require an increase or decrease of at least 0.1% of
     the Conversion Price; provided, that any adjustments which by reason of
     this Section 7(b)(iv) are not required to be made shall be carried forward
     and taken into account in any subsequent adjustment. All calculations under
     this Section 7 shall be made to the nearest cent or to the nearest
     one-hundredth of a share, as the case may be.

     (c) In case of any capital reorganization or reclassification of
outstanding shares of Common Stock (other than a reclassification covered by
Section 7(b)(i)), or in case of any consolidation or merger of the Corporation
with or into another Person, or in case of any sale or conveyance to another
Person of the property of the Corporation as an entirety or substantially as an
entirety (each of the foregoing being referred to as a "Transaction"), each
share of Series B Preferred Stock then outstanding shall thereafter be
convertible into, in lieu of the Common Stock issuable upon such conversion
prior to the consummation of such Transaction, the kind and amount of shares of
stock and other securities and property (including cash) receivable upon the
consummation of such transaction by a holder of that number of shares of Common
Stock into which one share of Series B Preferred Stock was convertible
immediately prior to such Transaction (including, on a pro rata basis, the cash,
securities or property received by holders of Common Stock in any tender or
exchange offer that is a step in such Transaction). In any such case, if
necessary, appropriate adjustment (as determined in good faith by the Board of
Directors) shall be made in the application of the provisions set forth in this
Section 7 with respect to rights and interests thereafter of the holders of
shares of Series B Preferred Stock to the end that the provisions set forth
herein for the protection of the conversion rights of the Series B Preferred
Stock shall thereafter be applicable, as nearly as reasonably may be, to any
such other shares of stock and other securities and property deliverable upon
conversion of the shares of Series B Preferred Stock remaining outstanding (with
such adjustments in the conversion price and number of shares issuable upon
conversion and such other adjustments in the provisions hereof as the Board of
Directors shall determine in good faith to be appropriate). In case securities
or property other than Common Stock shall be issuable or deliverable upon
conversion as aforesaid, then all references in this Section 7 shall be deemed
to apply, so far as appropriate and as nearly as may be, to such other
securities or property.

     Notwithstanding anything contained herein to the contrary, the Corporation
will not effect any Transaction unless, prior to the consummation thereof, (i)
the Surviving Person thereof, if other than the Corporation, shall assume, by
written instrument mailed to each record holder of shares of Series B Preferred
Stock, at such holder's address as it appears on the transfer books of the
Corporation, the obligation to deliver to such holder such cash, property and
securities to which, in accordance with the foregoing provisions, such holder is
entitled. Nothing contained in this Section 7(c) shall limit the rights of
holders of the Series B Preferred Stock to convert the Series B Preferred Stock
in connection with the Transaction or to exercise their rights to require the
redemption of the Series B Preferred Stock under Section 4(b).

     (d) The holder of any shares of Series B Preferred Stock may exercise its
right to convert such shares into shares of Common Stock by surrendering for
such purpose to the Corporation, at its principal office or at such other office
or agency maintained by the Corporation for that purpose, a certificate or
certificates representing the shares of Series B Preferred Stock to be converted
duly endorsed to the Corporation in blank accompanied by a written notice
stating that such holder elects to convert all or a specified whole number of
such shares in accordance with the provisions of this Section 7. The Corporation
will pay any and all documentary, stamp or similar issue or transfer tax and any
other taxes that may be payable in respect of any issue or delivery of shares of
Common Stock on conversion of Series B Preferred Stock pursuant hereto. As
promptly as practicable, and, in any event, within three Business Days after the
surrender of such certificate or certificates and the receipt of such notice
relating thereto and, if applicable, payment of all transfer taxes (or the
demonstration to the satisfaction of the Corporation that such taxes are
inapplicable), the Corporation shall deliver or cause to be delivered (i)
certificates registered in the name of such holder representing the number of
validly issued, fully paid and nonassessable full shares of Common Stock to
which the holder of shares of Series B Preferred Stock so
                                       -9-
<PAGE>   180

converted shall be entitled and (ii) if less than the full number of shares of
Series B Preferred Stock evidenced by the surrendered certificate or
certificates are being converted, a new certificate or certificates, of like
tenor, for the number of shares evidenced by such surrendered certificate or
certificates less the number of shares converted. Such conversion shall be
deemed to have been made at the close of business on the date of receipt of such
notice and of such surrender of the certificate or certificates representing the
shares of Series B Preferred Stock to be converted so that the rights of the
holder thereof as to the shares being converted shall cease except for the right
to receive shares of Common Stock, and the person entitled to receive the shares
of Common Stock shall be treated for all purposes as having become the record
holder of such shares of Common Stock at such time.

     (e) Shares of Series B Preferred Stock may be converted at any time and, if
subject to Mandatory Redemption, up to the close of business on the last
Business Day immediately preceding the date fixed for such Mandatory Redemption
of such shares.

     (f) In connection with the conversion of any shares of Series B Preferred
Stock, no fractions of shares of Common Stock shall be issued, but in lieu
thereof the Corporation shall pay a cash adjustment in respect of such
fractional interest in an amount equal to such fractional interest multiplied by
the Current Market Price per share of Common Stock on the day on which such
shares of Series B Preferred Stock are deemed to have been converted.

     (g) In case at any time or from time to time the Corporation shall pay any
dividend or make any other distribution to the holders of its Common Stock in
additional shares of stock of any class, or shall offer for subscription pro
rata to the holders of its Common Stock any additional shares of stock of any
class or any other right, other than pursuant to the Rights Plan, or there shall
be any capital reorganization or reclassification of the Common Stock of the
Corporation or consolidation or merger of the Corporation with or into another
corporation, or any sale or conveyance to another corporation of the property of
the Corporation as an entirety or substantially as an entirety, or there shall
be a voluntary or involuntary dissolution, liquidation or winding-up of the
Corporation, then, in any one or more of said cases the Corporation shall give
at least 20 days' prior written notice (the time of mailing of such notice shall
be deemed to be the time of giving thereof) to the registered holders of the
Series B Preferred Stock at the addresses of each as shown on the books of the
Corporation of the date on which (i) the books of the corporation shall close or
a record shall be taken for such stock dividend, distribution or subscription
rights or (ii) such reorganization, reclassification, consolidation, merger,
sale or conveyance, dissolution, liquidation or winding-up shall take place, as
the case may be, provided that in the case of any Transaction to which Section
7(c) applies the Corporation shall give at least 30 days' prior written notice
as aforesaid. Such notice shall also specify the date, if known, as of which the
holders of the Common Stock and of the Series B Preferred Stock of record shall
participate in said dividend, distribution or subscription rights or shall be
entitled to exchange their Common Stock or Series B Preferred Stock for
securities or other property deliverable upon such reorganization,
reclassification, consolidation, merger, sale or conveyance, or participate in
such dissolution, liquidation or winding-up, as the case may be.

     (h) Notwithstanding the provisions of this Section 7, no holder of Series B
Preferred Stock shall be permitted to convert a number of its shares of Series B
Preferred Stock which shall result in such holder and its Affiliates or any
group (as such term is used in Section 13(d)(3) of the Exchange Act) of which
any of them is a member having Beneficial Ownership, after giving effect to such
conversion, of more than 49% of the then-outstanding Common Stock. If a holder
requests conversion of shares of Series B Preferred Stock which would result in
ownership by such holder and its Affiliates or any group (as such term is used
in Section 13(d)(3) of the Exchange Act) of which any of them is a member of
more than 49% of the outstanding Common Stock after giving effect to such
conversion, then such holder's conversion request shall be deemed to represent a
request to convert up to the maximum number of shares of Series B Preferred
Stock permitted under the prior sentence and the Corporation shall deliver or
cause to be delivered, along with the Common Stock certificates and the new
certificate or certificates represent the remaining unconverted shares of Series
B Preferred Stock, a calculation in reasonable detail setting forth the maximum
number of shares convertible by such holder pursuant to the provisions of this
Section 7(h). If a holder of Series B Preferred Stock requests conversion of
such stock at the time it also requests conversion of any convertible debt of
the Corporation which it holds, then any limitation on conversion set forth in
such debt shall be applied first so as to permit the conversion of the maximum
amount of Series B Preferred Stock, subject to the beneficial ownership
limitation set forth above. If a holder is subject to
                                      -10-
<PAGE>   181

the limitation on conversion set forth in the first sentence of this Section
7(h), then such holder shall not be permitted to convert shares of Series B
Preferred Stock which were rendered non-convertible by the first sentence hereof
and have subsequently become convertible under the first sentence hereof for a
period of 75 days after such shares would otherwise first have become
convertible under the first sentence hereof (it being understood that
transferees of such shares whose beneficial ownership of Common Stock would not
exceed 49% of the then-outstanding Common Stock after giving effect to
conversion of their convertible securities, including the Series B Preferred
Stock, shall not be subject to any of the foregoing limitations on the amount or
timing of the conversion of shares of Series B Preferred Stock).

     (i) If the Corporation issues any securities convertible into any equity
security of the Corporation which contains any provisions that protect the
holder thereof against dilution upon the occurrence of certain events in a
manner more favorable to such holder than those set forth in this section (other
than a provision specifying an initial exercise or conversion price), such
provisions shall be deemed to be incorporated herein with respect to such events
as if fully set forth herein and to the extent any existing provision herein is
inconsistent with such provision, such incorporated provision shall be
substituted therefor.

     (j) If at the time of conversion of shares of Series B Preferred Stock, the
Common Stock of the Corporation is listed on a national securities exchange, or
is designated as a "national market system security" or "small cap market
security" on NASDAQ, the Corporation shall take all action necessary to cause
the shares of Common Stock issuable upon conversion of such shares of Series B
Preferred Stock to be listed on such exchange, subject to official notice of
issuance.

     (k) If the Corporation shall issue shares of Common Stock upon conversion
of the shares of Series B Preferred Stock as contemplated by this Section 7, the
Corporation shall issue together with each such share of Common Stock one Right
(as such term is defined in the Rights Plan) (or other securities in lieu
thereof), or any rights issued to holders of Common Stock in addition thereto or
in replacement therefor, whether or not such rights shall be exercisable at such
time, but only if such rights are issued and outstanding and held by other
holders of Common Stock at such time and have not expired, and only if the
Person to whom such shares of Common Stock are issued is not an "Acquiring
Person" under the Rights Plan or such other agreement pursuant to which such
rights are issued; provided, however, that, in such event such rights shall be
issued to such Person promptly after such time at which such Person is no longer
an "Acquiring Person."

     SECTION 8.  REPORTS AS TO ADJUSTMENTS AND OUTSTANDING SHARES. Whenever the
number of shares of Common Stock into which each share of Series B Preferred
Stock is convertible (or the number of votes to which each share of Series B
Preferred Stock is entitled) is adjusted as provided in Section 7, the
Corporation shall promptly mail to the holders of record of the outstanding
shares of Series B Preferred Stock at their respective addresses as the same
shall appear in the Corporation's stock records a notice stating that the number
of shares of Common Stock into which the shares of Series B Preferred Stock are
convertible has been adjusted and setting forth the new number of shares of
Common Stock (or describing the new stock, securities, cash or other property)
into which each share of Series B Preferred Stock is convertible, as a result of
such adjustment, a brief statement of the facts requiring such adjustment and
the computation thereof, and when such adjustment became effective.

     At the request of any holder of Series B Preferred Stock the Corporation
shall reasonably promptly issue to such holder, in any reasonable manner
requested by such holder, a notice setting forth the number of shares of Common
Stock then outstanding and the maximum number of shares into which the holder's
shares of Series B Preferred Stock are then convertible.

(together with all Accrued Interest) shall be paid in full by the Company on the

in kind" by the delivery to the Holder of an additional note (a "PIK Note")
identical in all respects to this Note except (a) registered in the name of the
Holder and (b) in the principal amount equal to the amount of interest then due

Business Days before such payment is due, by wire transfer of immediately
available funds no later than 2:00 p.m. on the due date of such payment. Before

payment or permit the collection of interest in excess of the maximum rate which
is permitted by Law. If any such excess interest is provided for herein, or
shall be adjudicated to be so provided for, then the Company shall not be
obligated to pay such interest in excess of the maximum rate permitted by Law,

any other provisions in this Note or in the Securities Purchase Agreement to the

entitled to the benefits, and is subject to the terms and conditions thereof as

     SECTION 3.  REDEMPTION OF NOTES.

     3.1 Mandatory Redemption Offer.

     (a) In the event there occurs a Change in Control, the Company shall offer
to purchase from each Holder all of the Notes held by such Holder for an amount
in cash equal to the greater of (i) the principal amount of the Notes held by
such Holder plus Accrued Interest through the date of purchase, and (ii) the
Fair Market Value (as defined below) of the cash, securities and other property
that such Holder of the Notes would have received had it converted its Notes
(including for such purposes any Notes issuable in respect of Accrued Interest)
into shares of Common Stock immediately prior to such Change in Control, plus
Accrued Interest payable in cash to the extent not otherwise reflected pursuant
to the parenthetical phrase of this clause (ii), (the greater of (i) and (ii)
above being referred to as the ("Change in Control Redemption Price"), in each
case by delivery of a notice in accordance with Section 3.1(b). In the event of
a Change in Control, each Holder of Notes shall have the right (but not the
obligation) to require the Company to purchase any or all of the Notes held by
such Holder for an amount in cash equal to the Change in Control Redemption
Price. Each Holder of Notes shall also be permitted, until 20 Business Days
following the date of the mailing to it of the Company's notice described in
Section 3.1(b)(i), to convert all, and not less than all, of the Notes held by
such Holder (including Notes issuable to such Holder as Accrued Interest that
have accelerated or will accelerate as a result of a Change in Control) pursuant
to Section 4 below; provided that any shares of Common Stock issuable upon
conversion of any Notes converted pursuant to this sentence after a Change in
Control has occurred shall be entitled to receive the same amount of cash,
securities and other property in connection with such Change in Control as the
Common Stock outstanding prior to the Change in Control. In the event a Holder
of Notes does not elect to have all of its Notes either (i) redeemed by the
Company pursuant to this Section 3 or (ii) converted pursuant to Section 4
below, in each case in connection with a specific Change in Control event, then
no interest shall be deemed to have been accelerated in connection with such
Change in Control. In the event that any Holder does not elect to convert or
redeem such Holder's Notes pursuant to the foregoing sentence, such Holder shall
retain any rights it has to convert or redeem its Notes in connection with any
subsequent Change in Control. "Fair Market Value" with respect to any securities
shall be the Current Market Price thereof as of the close of business on the
date of measurement. The Fair Market Value of any asset other than cash and
securities shall be determined jointly and in good faith by the Company and the
Required Noteholders. In the event any dispute between the Company and the
Required Noteholders as to the Fair Market Value or Current Market Price (which
dispute remains unresolved for 10 Business Days), such dispute shall be
submitted for final determination to a mutually acceptable investment banking
firm of national reputation familiar with the valuation of companies in the
hospitality and lodging industry ("Investment Banking Firm"). In the event that
the Company and the Required Noteholders cannot agree on a mutually acceptable
Investment Banking Firm within 10 Business Days, the Company, on the one hand,
and the Required Noteholders, on the other hand, shall each select one
Investment Banking Firm, which two investment banking firms shall jointly make
such determination within 20 business days after the date of such event, or, if
such two Investment Banking Firms are unable to agree on such determination, the
two Investment Banking Firms shall, by the end of the 20th business day after
the date of such event, select a third Investment Banking Firm and notify such
third Investment Banking Firm in writing (with a copy to the Company and the
Holders) of their respective determinations of the Fair Market Value or Current
Market Price following which such third Investment Banking Firm shall, within 15
business days after the date of its selection, notify the Company and the
Holders in writing of its selection of one or the other of the two original
determinations of the Fair Market Value or Current Market Price, which
determination shall be final and binding on the Company and the Holders. The
fees and expenses of any such determination shall be borne by the Company.

     (b) (i) Within five Business Days following an event giving a Holder of
Notes the right, pursuant to Section 3.1(a), to require the Company to redeem
all of such Notes, the Company shall give notice by mail to each Holder of
Notes, at such Holder's address as it appears on the Note Register, of such
event, which notice shall set forth each Holder's right to convert all, and not
less than all of the Notes held by such Holder, or to require the Company to
redeem all, but not less than all, of the Notes held by such Holder which are
eligible for redemption pursuant to the terms of Section 3.1(a), the redemption
date (which date shall be no more than 30 Business Days following the date of
such mailed notice), and the procedures to be followed by such Holder in
exercising its right to cause such redemption or effect such conversion. In the
event a record Holder of Notes shall

                                       -5-
<PAGE>   193

elect to require the Company to redeem all such Notes pursuant to Section
3.1(a), such Holder shall deliver, within 20 Business Days of the mailing to it
of the Company's notice described in this Section 3.1(b)(i), a written notice to
the Company so stating, specifying the principal amount of Notes to be redeemed
pursuant to Section 3.1(a). The Company shall, in accordance with the terms
hereof, redeem the principal amount of Notes so specified on the date fixed for
redemption. Failure of the Company to give any notice required by this Section
3.1(b)(i), or the formal insufficiency of any such notice, shall not prejudice
the rights of any Holders of Notes to cause the Company to redeem or to convert
all such Notes held by them. Notwithstanding the foregoing, the Board of
Directors of the Company may modify any offer pursuant to this Section 3.1(b)(i)
to the extent necessary to comply with the Exchange Act and the rules and
regulations thereunder.

     (ii) The Company shall publish the fact that it is redeeming, or offering
to redeem, Notes through a nationally prominent newswire service on or before
the date of mailing any notice of redemption or right of redemption. At any time
after a notice of redemption shall have been mailed and before such date of
redemption the Company may deposit for the benefit of the Holders of the Notes
called for redemption the funds necessary for such redemption with a bank or
trust company doing business in the Borough of Manhattan, the City of New York,
and having a capital and surplus of at least $1,000,000,000. Any interest
allowed on moneys so deposited shall be paid to the Company. Upon the deposit of
such funds or, if no such deposit is made, upon the date fixed for redemption
(unless the Company shall default in making payment of the appropriate
redemption amount), whether or not Notes so called for redemption have been
surrendered for cancellation, the Notes to be redeemed shall be deemed to be no
longer outstanding and the Holders thereof shall cease to be Holders with
respect to such Notes and shall have no rights with respect thereto, except for
the rights to receive the amount payable upon redemption, but without interest,
and, up to the close of business on the date immediately preceding the date
fixed for such redemption, the right to convert such Notes pursuant to Section 4
hereof. Such deposit in trust shall be irrevocable except that any funds
deposited by the Company which shall not be required for the redemption for
which they were deposited because of the exercise of conversion rights shall be
returned to the Company forthwith, and any funds deposited by the Company which
are unclaimed at the end of one year from the date fixed for such redemption
shall be paid over to the Company upon its request, and upon such repayment the
Holders of the Notes so called for redemption shall look only to the Company for
payment of the appropriate amount. Any such unclaimed amounts paid over to the
Company shall, for a period of six years from the date fixed for such
redemption, be set apart and held by the Company in trust for the benefit of the
Holders of such Notes, but no such Holder shall be entitled to interest thereon.
At the expiration of such six-year period, all right, title, interest and claim
of such Holders in or to such unclaimed amounts shall be extinguished,
terminated and discharged, and such unclaimed amounts shall become part of the
general funds of the Company free of any claim of such Holders.

     SECTION 4.  CONVERSION OF NOTES.

     4.1. Holder's Option to Convert Notes into Common Stock.

     (a) This Note or any portion of the outstanding principal amount of such
Note, including any Notes issued as PIK Notes under Section 1.3 of this Note,
shall be convertible at the option of the Holder at any time after the Closing
into a number of shares of Class A Common Stock, on the terms and conditions set
forth in this Section 4.

     (b) Subject to the provisions for adjustment hereinafter set forth, each
Note shall be convertible in the manner hereinafter set forth into a number of
fully paid and nonassessable shares of Class A Common Stock equal to the product
obtained by multiplying the Applicable Conversion Rate by the outstanding
principal amount of this Note or portion thereof being converted. The
"Applicable Conversion Rate" means the quotient obtained by dividing the
Conversion Value on the date of conversion by the Conversion Price as adjusted
pursuant to Section 4.1(c) on the date of conversion.

     (c) The Conversion Price shall be subject to adjustment from time to time
as follows:

          (i) In case the Company shall at any time or from time to time after
     the original issuance of the Notes declare a dividend, or make a
     distribution, on the outstanding shares of Common Stock in either case, in
     shares of Common Stock, or effect a subdivision, combination, consolidation
     or reclassification of the

                                       -6-
<PAGE>   194

     outstanding shares of Common Stock into a greater or lesser number of
     shares of Common Stock, then, and in each such case, the Conversion Price
     in effect immediately prior to such event or the record date therefor,
     whichever is earlier, shall be adjusted by multiplying such Conversion
     Price by a fraction, the numerator of which is the number of shares of
     Common Stock that were outstanding immediately prior to such event and the
     denominator of which is the number of shares of Common Stock outstanding
     immediately after such event. An adjustment made pursuant to this Section
     4.1(c)(i) shall become effective (x) in the case of any such dividend or
     distribution, immediately after the close of business on the record date
     for the determination of holders of shares of Common Stock entitled to
     receive such dividend or distribution, or (y) in the case of any such
     subdivision, reclassification, consolidation or combination, at the close
     of business on the day upon which such corporate action becomes effective.

          (ii) In case the Company shall issue (other than upon the exercise of
     options, rights or convertible securities) shares of Common Stock (or
     options, rights, warrants or other securities convertible into or
     exchangeable for shares of Common Stock) at a price per share (or having an
     exercise or conversion price per share) less than the Current Market Price
     as of the Measurement Date, other than (x) in a transaction to which
     Section 1.3 applies, (y) pursuant to options or other securities under any
     employee or director benefit plan or program of the Company approved by the
     Board of Directors of the Company or shares of Common Stock issued upon the
     exercise thereof, (z) pursuant to the conversion of the Notes, the Series B
     Preferred Stock, or the Class B Common Stock or Class C Common Stock (the
     issuances under clauses (x), (y) and (z) being referred to as "Excluded
     Issuances"), then, and in each such case, the Conversion Price in effect
     immediately prior to the Measurement Date shall be reduced so as to be
     equal to an amount determined by multiplying such Conversion Price by a
     fraction of which the numerator shall be the number of shares of Common
     Stock of all classes outstanding at the close of business on the
     Measurement Date plus the number of shares of Common Stock (or the number
     of shares of Common Stock issuable upon the conversion, exchange or
     exercise of such options, rights, warrants or other securities convertible
     into or exchangeable for shares of Common Stock) which the aggregate
     consideration receivable by the Company in connection with such issuance
     would purchase at such Current Market Price and the denominator shall be
     the number of shares of Common Stock of all classes outstanding at the
     close of business on the Measurement Date plus the number of shares of
     Common Stock (or the number of shares of Common Stock issuable upon the
     conversion, exchange or exercise of such options, rights, warrants or other
     securities convertible into or exchangeable for shares of Common Stock) so
     issued. For purposes of this Section 4.1(c)(ii), the aggregate
     consideration receivable by the Company in connection with the issuance of
     shares of Common Stock or of options, rights, warrants or other convertible
     securities shall be deemed to be equal to the sum of the gross offering
     price (before deduction of customary underwriting discounts or commissions
     and expenses payable to third parties) of all such securities plus the
     minimum aggregate amount, if any, payable upon conversion or exercise of
     any such options, rights, warrants or other convertible securities into
     shares of Common Stock, less any original issue discount, premiums and
     other similar incentives which have the effect of reducing the effective
     price per share. For purposes of this Section 4.1(c)(ii), such adjustment
     shall become effective immediately prior to the opening of business on the
     Business Day immediately following the Measurement Date.

          (iii) No adjustment in the Conversion Price shall be required unless
     such adjustment would require an increase or decrease of at least 0.1% of
     the Conversion Price; provided, that any adjustments which by reason of
     this Section 4.1(c)(iii) are not required to be made shall be carried
     forward and taken into account in any subsequent adjustment. All
     calculations under this Section 4 shall be made to the nearest cent or to
     the nearest one-hundredth of a share, as the case may be.

     (d) In case of any capital reorganization or reclassification of
outstanding shares of Common Stock (other than a reclassification covered by
Section 4.1(c)(i)), or in case of any consolidation or merger of the Company
with or into another Person, or in case of any sale or conveyance to another
Person of the property of the Company as an entirety or substantially as an
entirety (each of the foregoing being referred to as a "Transaction"), each Note
then outstanding shall thereafter be convertible into, in lieu of the Common
Stock issuable upon such conversion prior to the consummation of such
Transaction, the kind and amount of shares of stock and other securities and
property (including cash) receivable upon the consummation of such Transaction

                                       -7-
<PAGE>   195

by a holder of that number of shares of Common Stock into which such Note was
convertible immediately prior to such Transaction (including, on a pro rata
basis, the cash, securities or property received by holders of Common Stock in
any tender or exchange offer that is a step in such Transaction). In any such
case, if necessary, appropriate adjustment (as determined in good faith by the
Board of Directors) shall be made in the application of the provisions set forth
in this Section 4 with respect to rights and interests thereafter of the Holders
of Notes to the end that the provisions set forth herein for the protection of
the conversion rights of the Notes shall thereafter be applicable, as nearly as
reasonably may be, to any such other shares of stock and other securities and
property deliverable upon conversion of the Notes remaining outstanding (with
such adjustments in the Conversion Price and number of shares issuable upon
conversion and such other adjustments in the provisions hereof as the Board of
Directors shall determine in good faith to be appropriate). In case securities
or property other than Common Stock shall be issuable or deliverable upon
conversion as aforesaid, then all references in this Section 4 shall be deemed
to apply, so far as appropriate and as nearly as may be, to such other
securities or property.

     Notwithstanding anything contained herein to the contrary, the Company will
not effect any Transaction unless, prior to the consummation thereof, the
Surviving Person thereof, if other than the Company, shall assume, by written
instrument mailed to each record Holder of Notes, at such Holder's address as it
appears in the Note Register, the obligation to deliver to such Holder such
cash, property and securities to which, in accordance with the foregoing
provisions, such Holder is entitled. Nothing contained in this Section 4.1(d)
shall limit the rights of Holders of the Notes to convert the Notes in
connection with the Transaction or to exercise their rights to require the
redemption of the Notes under Section 3.

     (e) Conversion of this Note may be effected by the Holder upon the
surrender to the Company at the office of the Company designated for notices in
accordance with Section 8.4 or at the office of any agent or agents of the
Company, as may be designated by the Board of Directors, of this Note,
accompanied by a written notice (a "Note Holder Conversion Notice") stating that
such Holder elects to convert all or a specified portion of the outstanding
principal amount of this Note in accordance with the provisions of this Section
4.1 and specifying the name or names in which such Holder wishes the certificate
or certificates for shares of Common Stock to be issued. In case the Holder's
Note Holder Conversion Notice shall specify a name or names other than that of
such Holder, such notice shall be accompanied by payment of all transfer Taxes
payable upon the issuance of shares of Common Stock in such name or names that
would not have been incurred had such shares of Common Stock been issued in the
name of the Holder. Other than such Taxes, the Company will pay any and all
issue and other Taxes, whether or not imposed on the Company (other than taxes
based on income) that may be payable in respect of any issue or delivery of
shares of Common Stock on conversion of this Note pursuant hereto. As promptly
as practicable, and in any event within five (5) Business Days after the
surrender of such Note and, if applicable, the receipt of a Note Holder
Conversion Notice relating thereto by the Company and, if applicable, payment of
all transfer Taxes (or the demonstration to the satisfaction of the Company that
such taxes have been paid), the Company shall deliver or cause to be delivered
(i) certificates representing the number of validly issued, fully paid and
nonassessable full shares of Common Stock to which the Holder of the Note shall
be entitled and (ii) if less than the entire outstanding principal amount of
this Note is being converted, a new Note in the principal amount which remains
outstanding upon such partial conversion. The date of delivery of this Note
after or together with the delivery of a Note Holder Conversion Notice shall be
deemed to be the date of conversion.

     (f) Notes may be converted at any time up to the close of business on the
last Business Day immediately preceding the Due Date.

     (g) In connection with the conversion of any Notes, no fractions of shares
of Common Stock shall be issued, but in lieu thereof the Company shall pay a
cash adjustment in respect of such fractional interest in an amount equal to
such fractional interest multiplied by the Current Market Price per share of
Common Stock on the day on which such Notes are deemed to have been converted.

     (h) In case at any time or from time to time the Company shall pay any
dividend or make any other distribution to the holders of its Common Stock in
additional shares of stock of any class, or shall offer for subscription pro
rata to the holders of its Common Stock any additional shares of stock of any
class or any other right, other than pursuant to the Rights Plan, or there shall
be any capital reorganization or reclassification of the Common Stock of the
Company or consolidation or merger of the Company with or into another company,
or any

                                       -8-
<PAGE>   196

sale or conveyance to another company of the property of the Company as an
entirety or substantially as an entirety, or there shall be a voluntary or
involuntary dissolution, liquidation or winding up of the Company, then, in any
one or more of said cases the Company shall give at least 20 days' prior written
notice (the time of mailing of such notice shall be deemed to be the time of
giving thereof) to the Holders of the Notes at the addresses of each as shown in
the Note Register of the date on which (i) the books of the Company shall close
or a record shall be taken for such stock dividend, distribution or subscription
rights or (ii) such reorganization, reclassification, consolidation, merger,
sale or conveyance, dissolution, liquidation or winding up shall take place, as
the case may be, provided that in the case of any Transaction to which Section
4.1(d) applies the Company shall give at least 30 days' prior written notice as
aforesaid. Such notice shall also specify the date, if known, as of which the
holders of the Common Stock and the Holders of the Notes shall participate in
said dividend, distribution or subscription rights or shall be entitled to
exchange their Common Stock or Notes for securities or other property
deliverable upon such reorganization, reclassification, consolidation, merger,
sale or conveyance, or participate in such dissolution, liquidation or winding
up, as the case may be.

     (i) Notwithstanding the provisions of this Section 4.1, no Holder of Notes
shall be permitted to convert all or any portion of the principal amount of its
Notes which shall result in such Holder and its Affiliates or any group (as such
term is used in Section 13(d)(3) of the Exchange Act) of which any of them is a
member having Beneficial Ownership, after giving effect to such conversion, of
more than 49% of the then-outstanding Common Stock. If a Holder requests
conversion of Notes which would result in ownership by such Holder and its
Affiliates or any group (as such term is used in Section 13(d)(3) of the
Exchange Act) of which any of them is a member of more than 49% of the
outstanding Common Stock after giving effect to such conversion, then such
Holder's conversion request shall be deemed to represent a request to convert up
to the maximum principal amount of Notes permitted under the prior sentence and
the Company shall deliver or cause to be delivered, along with the Common Stock
certificates and the new Note representing the remaining unconverted principal
amount of such Notes, a calculation in reasonable detail setting forth the
maximum principal amount of such Notes convertible by such holder pursuant to
the provisions of this Section 4.1(i). If a Holder is subject to the limitation
on conversion set forth in the first sentence of this Section 4.1(i), then such
Holder shall not be permitted to convert Notes which were rendered
non-convertible by the first sentence hereof and have subsequently become
convertible under the first sentence hereof for a period of 75 days after such
Notes would otherwise first have become convertible under the first sentence
hereof (it being understood that transferees of the Note whose Beneficial
Ownership of Common Stock would not exceed 49% of the then-outstanding Common
Stock, after giving effect to the conversion of their Notes, shall not be
subject to any of the foregoing limitations on the amount or timing of the
conversion of the Note).

     (j) If the Company issues any securities convertible into any equity
security of the Company which contains any provisions that protect the holder
thereof against dilution upon the occurrence of certain events in a manner more
favorable to such holder than those set forth in this Section 4.1 (other than a
provision specifying an initial exercise or conversion price), such provisions
shall be deemed to be incorporated herein with respect to such events as if
fully set forth herein and to the extent any existing provision herein is
inconsistent with such provision, such incorporated provision shall be
substituted therefor.

     4.2. Reports as to Adjustments and Outstanding Shares.

     (a) Whenever the number of shares of Common Stock into which each Note is
convertible is adjusted as provided in Section 4.1, the Company shall promptly
mail to the Holders of the outstanding Notes at their respective addresses as
the same shall appear in the Note Register a notice stating that the number of
shares of Common Stock into which the Notes are convertible has been adjusted
and setting forth the new number of shares of Common Stock (or describing the
new stock, securities, cash or other property) into which each Note is
convertible, as a result of such adjustment, a brief statement of the facts
requiring such adjustment and the computation thereof, and when such adjustment
became effective.

     (b) At the request of any Holder the Company shall reasonably promptly
issue to such Holder, in any reasonable manner requested by such Holder, a
notice setting forth the number of shares of Common Stock then outstanding and
the maximum number of shares into which the Note is then convertible.

                                       -9-
<PAGE>   197

     4.3. Reservation of Stock; Listing Rights.

     (a) The Company shall at all times reserve and keep available for issuance
upon the conversion of the Notes, free from any preemptive rights, such number
of its authorized but unissued shares of Common Stock as will from time to time
be sufficient to permit the conversion of the entire outstanding principal
amount of the Notes into Common Stock, and shall take all action required to
increase the authorized number of shares of Common Stock, if necessary, to
permit the conversion of the entire outstanding principal amount of the Notes.

     (b) If at the time of conversion of any Notes, the Common Stock of the
Company is listed on a national securities exchange, or is designated as a
"national market system security" or "small cap market security" on NASDAQ, the
Company shall take all action necessary to cause the shares of Common Stock
issuable upon conversion of such Notes to be listed on such exchange, subject to
official notice of issuance.

     (c) If the Company shall issue shares of Common Stock upon conversion of
the Notes as contemplated by this Section 4, the Company shall issue together
with each such share of Common Stock one Right (as such term is defined in the
Rights Plan) (or other securities in lieu thereof), or any rights issued to
holders of Common Stock in addition thereto or in replacement therefor, whether
or not such rights shall be exercisable at such time, but only if such rights
are issued and outstanding and held by other holders of Common Stock at such
time and have not expired, and only if the Person to whom such shares of Common
Stock are issued is not an "Acquiring Person" under the Rights Plan or such
other agreement pursuant to which such rights are issued; provided, however,
that, in such event such rights shall be issued to such Person promptly after
such time at which such Person is no longer an "Acquiring Person."

     SECTION 5.  EVENTS OF DEFAULT AND REMEDIES.

     5.1. Events of Default. Each of the following shall constitute an Event of
Default with respect to this Note:

     (a) Nonpayment of Principal of the Notes. If the Company fails to pay the
principal of or any other sum (other than interest), if any, due on any of the
Notes, when and as the same becomes due and payable, whether at the maturity
thereof, on a date fixed for a redemption, or otherwise;

     (b) Nonpayment of Interest. If the Company fails to pay interest on any of
the Notes in full, when and as the same becomes due and payable, and such
failure shall be continuing for five (5) Business Days;

     (c) Voluntary Bankruptcy and Insolvency Proceedings. If the Company or any
Subsidiary shall file a petition in bankruptcy or for reorganization or for an
arrangement or any composition, readjustment, liquidation, dissolution or
similar relief pursuant to the Bankruptcy Code, or under any similar present or
future federal law or the law of any other jurisdiction or shall be adjudicated
a bankrupt or become insolvent, or consent to the appointment of or taking
possession by a receiver, liquidator, assignee, trustee, custodian, sequestrator
(or other similar official) of the Company or such Subsidiary or for all or any
substantial part of its respective property, or the Company or any of its
Subsidiaries shall make an assignment for the benefit of its creditors, or shall
admit in writing its inability to pay its debts generally as they become due, or
shall take any corporate action, as the case may be, in furtherance of any of
the foregoing;

     (d) Adjudication of Bankruptcy. If a petition or answer shall be filed
proposing the adjudication of the Company or any of its Subsidiaries as a
bankrupt or its reorganization or arrangement, or any composition, readjustment,
liquidation, dissolution or similar relief with respect to it pursuant to the
Bankruptcy Code or under any similar present or future federal law or the law of
any other jurisdiction applicable to the Company or any of its Subsidiaries, and
the Company or such Subsidiary (as applicable) shall consent to or acquiesce in
the filing thereof, or such petition or answer shall not be discharged or denied
within 60 days after the filing thereof;

     (e) Receivership or Sequestration. If a decree or order is rendered by a
court having jurisdiction (i) for the appointment of a receiver or custodian or
liquidator or trustee or sequestrator or assignee (or similar official) in
bankruptcy or insolvency of the Company or any of its Subsidiaries or of all or
a substantial part of its property, or for the winding-up or liquidation of its
affairs, and such decree or order shall have remained in force undischarged and
unstayed for a period of 60 days, or (ii) for the sequestration or attachment of
any property of the Company or any of its Subsidiaries without its return to the
possession of the Company or such Subsidiary (as applicable) or its release from
such sequestration or attachment within 60 days thereafter;
                                      -10-
<PAGE>   198

     (f) Acceleration of Other Indebtedness. If, during the Covenant Period,
default shall be made with respect to any Indebtedness of the Company (other
than the Notes) with a principal amount outstanding in excess of $1,500,000 with
the result that such Indebtedness can be accelerated so that the same will
become due and payable prior to the date on which the same would otherwise have
become due and payable;

     (g) Covenant Defaults. The Company shall have breached in any material
respect any of the covenants of the Company set forth in this Note or it shall
have breached its obligation, if any, to appoint or nominate for election to the
Company's Board of Directors any designee of the Investor under Section 3.1 of
the Investor Agreement; provided that, if capable of being remedied, such breach
continues for 15 days after notice to the Company in writing by any Holder of
this Note or other party entitled to the benefit of such covenant;

     (h) Judgments. A final judgment or judgments entered by a court of
competent jurisdiction for the payment of money aggregating in excess of
$1,500,000 is or are outstanding against the Company or any Subsidiary and any
one such judgment in excess of $1,500,000 has, or such judgments aggregating in
excess of $1,500,000 have, remained unpaid, unvacated, unbonded, or unstayed by
appeal or otherwise for a period of 30 days from the date of entry.

     5.2. Acceleration of Maturity. If any Event of Default shall have occurred
and be continuing, the Holders of a majority of the outstanding principal amount
of Notes may, by notice to the Company, declare the entire outstanding principal
balance of the Notes, and all accrued and unpaid interest thereon, to be due and
payable immediately, and upon any such declaration the entire outstanding
principal balance of this Note, and said accrued and unpaid interest shall
become and be immediately due and payable, without presentment, demand, protest
or other notice whatsoever, all of which are hereby expressly waived, anything
in this Note or the Securities Purchase Agreement to the contrary
notwithstanding; provided that if an Event of Default under clause (c), (d), or
(e) of Section 5.1 with respect to the Company shall have occurred, the
outstanding principal amount of this Note, and all accrued and unpaid interest
thereon, shall immediately become due and payable, without any declaration and
without presentment, demand, protest or other notice whatsoever, all of which
are hereby expressly waived, anything in this Note or the Securities Purchase
Agreement to the contrary notwithstanding.

     5.3. Other Remedies. If any Event of Default shall have occurred and be
continuing, from and including the date of such Event of Default to but not
including the date such Event of Default is cured or waived, the Holder may
enforce its rights by suit in equity, by action at law, or by any other
appropriate proceedings, whether for the specific performance (to the extent
permitted by law) of any covenant or agreement contained in this Note or the
Securities Purchase Agreement or in aid of the exercise of any power granted in
this Note or the Securities Purchase Agreement, and the Holder may enforce the
payment of this Note and any of its other legal or equitable rights.

     5.4. Conduct No Waiver; Collection Expenses. No course of dealing on the
part of the Holder, nor any delay or failure the part of the Holder to exercise
any of its rights, shall operate as a waiver of such right or otherwise
prejudice the Holder's rights, powers and remedies. If the Company fails to pay,
when due, the principal or the interest on this Note, the Company will pay to
the Holder to the extent permitted by law, on demand, all costs and expenses
incurred by the Holder in the collection of any amount due in respect of this
Note, including reasonable legal fees incurred by the Holder in enforcing its
rights hereunder.

     5.5 Annulment of Acceleration. If a declaration is made in accordance with
Section 5.2, then and in every such case, the Holders of at least a majority of
the outstanding principal amount of the Notes may, by an instrument delivered to
the Company, annul such declaration and the consequences thereof, provided that
at the time such declaration is annulled:

     (a) all arrears of interest on the Notes and all other sums payable on the
Notes and pursuant to the Securities Purchase Agreement (except any principal of
or interest or premium on the Notes which has become due and payable by reason
of such declaration) shall have been duly paid; and

     (b) every other Event of Default under each of the Notes shall have been
duly waived or otherwise made good or cured;

                                      -11-
<PAGE>   199

provided, however, that only the Purchaser or an Affiliate of the Purchaser (but
not any transferee thereof other than an Affiliate of the Purchaser) that is a
Holder of the Note or Notes with respect to which the declaration permitted by
the last proviso of Section 5.2 was made may annul such declaration; and
provided, further, that no such annulment shall extend to or affect any
subsequent Event of Default or impair any right consequent thereon.

     5.6. Remedies Cumulative, Etc. No right or remedy conferred upon or
reserved to the Holder of this Note is intended to be exclusive of any other
right or remedy, and every right and remedy shall be cumulative and in addition
to every other right and remedy given hereunder or now and hereafter existing
under applicable Law. Every right and remedy given by this Note or by applicable
Law to the Holder may be exercised from time to time and as often as may be
deemed expedient by such Holder. Notwithstanding the foregoing or any other
provision of this Section 5, the rights and obligations in this Note will be
subordinate as set forth in Section 6.

     SECTION 6.  SUBORDINATION OF NOTES.

     6.1. Subordination of Notes to Senior Indebtedness. The Indebtedness
evidenced by the Notes shall at all times be wholly subordinate and junior in
right of payment to any and all Senior Indebtedness of the Company (including
any claims by the holders of such Senior Indebtedness for interest accruing
after any assignment for the benefit of creditors by the Company or the
institution by or against the Company of any proceedings under the Bankruptcy
Code or any law for the relief of or relating to debtors, or any other claim by
such holders for any such interest which would have accrued in the absence of
such assignment or the institution of such proceedings) in the manner and with
the force and effect hereafter set forth:

     (a) In the event of any liquidation, dissolution or winding up of the
Company, or of any execution, sale, receivership, insolvency, bankruptcy,
liquidation, readjustment, reorganization or other similar proceeding relative
to the Company or its property, all sums owing on all Senior Indebtedness of the
Company (including cash collateral and amounts not yet due and payable) shall
first be paid in full in cash, or provision shall be made for such payment in
money or money's worth, before any payment is made upon the Notes; and if in any
such event any payment or distribution, whether in cash, property, or securities
shall be made upon or in respect of the Notes at a time when such payment is
prohibited under this Section 6, the same shall be paid over to the holders of
the Senior Indebtedness of the Company, pro rata, for application in payment
thereof unless and until such Senior Indebtedness shall have been paid or
satisfied in full in cash, or provision shall be made for such payment in money
or money's worth.

     In case of any assignment for the benefit of creditors by the Company or in
case any proceedings under the Bankruptcy Code or any other law for the relief
of or relating to debtors are instituted by or against the Company, or in case
of the appointment of any receiver for the Company's business or assets, or in
case of any dissolution or winding up of the affairs of the Company, the Company
and any assignee, trustee in bankruptcy, receiver, debtor in possession or other
person or persons in charge are hereby directed to pay to the holders of the
Senior Indebtedness of the Company the full amount of such holders' claims
against the Company (including interest to the date of payment) in cash, or
provision shall be made for such payment in money or money's worth, before
making any payments to the Holders of Notes, and insofar as may be necessary for
that purpose, the Holder hereby assigns and transfers to the holders of Senior
Indebtedness of the Company all rights to any payments, dividends or other
distributions.

     (b) In the event that all or any part of the Indebtedness evidenced by the
Notes is declared or becomes due and payable because of the occurrence of any
Event of Default or otherwise than at the option of the Company (other than
pursuant to its terms at its final maturity or upon a Change in Control), under
circumstances when the foregoing clause (a) shall not be applicable, the Holders
of the Notes consent, subject to Section 6.5, to the payment to holders of
Senior Indebtedness (or the provision, in a manner satisfactory to the holders
of Senior Indebtedness, for such payment) of such amounts as are then due and
payable pursuant to such Senior Indebtedness prior to the payment to the Holders
of Notes of any amount due and payable in respect of the Notes.

     (c) For purposes of this Section 6 only, the words "cash, property or
securities" shall (so long as the effect of this paragraph is not to cause the
Note to be treated in any case or proceeding or other event described in this
Section 6 as part of the same class of claims as any Senior Indebtedness or any
class of claims on a parity with or senior to any Senior Indebtedness for any
payment or distribution) not be deemed to include shares of stock of the

                                      -12-
<PAGE>   200

Company as reorganized or readjusted, or securities of the Company or any other
corporation provided for by a plan of reorganization or readjustment which are
subordinated in right of payment to all Senior Indebtedness which may at the
time be outstanding to substantially the same extent as, or to a greater extent
than, the Notes are so subordinated as provided in this Section 6.

     (d) All payments, cash, or noncash distributions made to the Holders of
Notes which should have been made to the holders of Senior Indebtedness of the
Company shall be received and held by the former in trust for the benefit of the
latter, and the Holders of Notes shall forthwith remit each such payment, cash,
or noncash distribution to the holders of the Senior Indebtedness of the
Company, pro rata, in the form in which it was received, together with such
endorsements or documents as may be necessary to effectively negotiate or
transfer the same to the holders of the Senior Indebtedness of the Company.

     (e) The Company shall not, at any time after the end of the Covenant
Period, pay the principal of, premium (if any) or interest on the Notes or make
any other payment to Holders of the Notes or repay, repurchase, redeem, defease
or otherwise retire any Notes (collectively, "pay the Notes") if (i) both (y)
any Senior Indebtedness is not paid when due in cash and (z) provision has not
been made for payment in full in a manner satisfactory to the holders of such
Senior Indebtedness or (ii) any other default on Senior Indebtedness occurs and
the maturity of such Senior Indebtedness is accelerated in accordance with its
terms unless, in either case, (x) the default has been cured or waived and any
such acceleration has been rescinded in writing or (y) such Senior Indebtedness
has been paid in full in cash or provision has been made for payment in full in
a manner satisfactory to the holders of such Senior Indebtedness; provided,
however, that the Company may pay the Notes without regard to the foregoing if
the Company and the Purchaser receive written notice approving such payment from
the representative of the Senior Indebtedness with respect to which either of
the events set forth in clause (i) or (ii) of this sentence has occurred or is
continuing. During the continuance of any Payment Blockage Period, the Company
may not pay the Notes. Notwithstanding the provisions of the immediately
preceding sentence, unless the holders of Senior Indebtedness which initiated
the Payment Blockage Period or the representative of such holders shall have
accelerated the maturity of the Senior Indebtedness, the Company may resume
payments on the Note after the end of such Payment Blockage Period. A "Payment
Blockage Period" commences on the receipt by the Company of a written notice (a
"Blockage Notice") from the representative of the holders of such Senior
Indebtedness of a default, other than a default set forth in clause (i) or (ii)
of the first sentence of this Section 6.1(e), on any Senior Indebtedness that
permits the holders of the Senior Indebtedness to accelerate its maturity
immediately without either further notice (except such notice as may be required
to effect such acceleration) or the expiration of any applicable grace periods,
specifying an election to effect a Payment Blockage Period and ends 90 days
thereafter. The Payment Blockage Period will end earlier if such Payment
Blockage Period is terminated (1) by written notice to the Company from the
Person or Persons who gave such Blockage Notice, (2) because the default giving
rise to such Blockage Notice is no longer continuing or (3) because such Senior
Indebtedness has been repaid in full or provision has been made for payment in
full in a manner satisfactory to the holders of such Senior Indebtedness. Not
more than one Blockage Notice may be given in any 360-day period, irrespective
of the number of defaults with respect to Senior Indebtedness during such
period.

     Notwithstanding anything set forth in this Section 6.1, nothing set forth
herein shall restrict Holders of the Notes from exercising their rights of
conversion hereunder.

     6.2. Proofs of Claim of Holders of Senior Indebtedness; Voting. Each Holder
of Notes undertakes and agrees for the benefit of each holder of Senior
Indebtedness of the Company to execute, verify, deliver and file any proofs of
claim relating to the Notes which any holder of such Senior Indebtedness may at
any time require in order to prove and realize upon any rights or claims
pertaining to the Notes and to effectuate the full benefit of the subordination

                               REGISTRATION RIGHTS

         2.1. Incidental Rights.

                  (a) If at any time or from time to time (but subject to the
         limitations on sales of Registrable Securities in the Investor
         Agreement) the Company proposes to file with the SEC a registration
         statement (whether on Form S-1, S-2, or S-3, or any equivalent form
         then in effect) for the registration under the Securities Act of any
         Subject Securities for sale, for cash consideration, to the public by
         the Company or on behalf of one or more securityholders of the Company
         (excluding any sale of securities upon conversion into or exchange or
         exercise for shares of Common Stock, and any shares of Common Stock
         issuable by the Company upon the exercise of employee stock options, or
         to any employee stock ownership plan, or in connection with any
         acquisition made by the Company, any securities exchange offer,
         dividend reinvestment plan, employee benefit plan, corporate
         reorganization, or in connection with any amalgamation, merger or
         consolidation of the Company or any direct or indirect subsidiary of
         the Company with one or more other corporations if the Company is the
         surviving corporation), the Company shall give Shareholder at least 20
         days' prior written notice of the proposed filing (or if 20 days'
         notice is not practicable, a reasonable shorter period to be not less
         than 7 days), which notice shall outline the nature of the proposed
         distribution and the jurisdictions in the United States in which the
         Company proposes to qualify and offer such securities (the "Elected
         Jurisdictions"). On the written request of Shareholder received by the
         Company within 15 days after the date of the Company's delivery to
         Shareholder of the notice of intended registration (which request shall
         specify the Registrable Securities sought to be disposed by Shareholder
         and the intended method or methods by which dispositions are intended
         to be made), the Company shall, under the terms and subject to the
         conditions of this Article II, at its own expense as provided in
         Section 4.1, include in the coverage of such registration statement (or
         in a separate registration statement concurrently filed) and qualify
         for sale under the blue sky or securities laws of the various states in
         the Elected Jurisdictions the number of Registrable Securities of the
         kind being registered (the "Specified Securities") held by Shareholder
         or into which the Registrable Securities are convertible, as the case
         may be, and which Shareholder has so requested to be registered or
         qualified for distribution, to the extent required to permit the
         distribution (in accordance with the intended method or methods


                                      -3-
<PAGE>   213

         thereof as aforesaid) in the Elected Jurisdictions requested by
         Shareholder of such Registrable Securities.

                  (b) If the distribution proposed to be effected by the Company
         involves an underwritten offering of the securities being so
         distributed by or through one or more underwriters, and if the managing
         underwriter of such underwritten offering indicates in writing its
         opinion that including all or part of the Specified Securities in the
         coverage of such registration statement or in the distribution to be
         effected by such prospectus will materially and adversely affect the
         sale of securities proposed to be sold (which opinion of the managing
         underwriter shall also state the maximum number of shares, if any,
         which can be sold by Shareholder requesting registration under this
         Section 2.1 without materially adversely affecting the sale of the
         securities proposed to be sold), then the number of Specified
         Securities which Shareholder shall have the right to include in such
         registration statement shall be reduced to the maximum number of shares
         or principal amount, in the case of debt, specified by the managing
         underwriter. First priority, after the absolute priority afforded to
         the Company, shall be afforded to the Specified Securities held by
         Shareholder and no securities proposed to be sold by Shareholder shall
         be so reduced until all securities proposed to be sold by all other
         parties (other than the Company) have been entirely eliminated.

                  (c) The Company shall have the sole right to select any
         underwriters, including the managing underwriter, of any public
         offering of securities made other than as a result of the rights
         granted in Section 2.2. Nothing in this Section 2.1 shall create any
         liability on the part of the Company to Shareholder if the Company for
         any reason decides not to file or to delay or withdraw a registration
         statement (which the Company may do in its sole discretion).

                  (d) Shareholder shall have the right to withdraw its request
         for inclusion of its Specified Securities in any registration statement
         pursuant to this Section 2.1 by giving written notice to the Company of
         its request to withdraw; provided, however, that (i) such request must
         be made in writing prior to the execution of the underwriting agreement
         (or such other similar agreement) with respect to such registration and
         (ii) such withdrawal shall be irrevocable and, after making such
         withdrawal, Shareholder shall no longer have any right to include
         Registrable Securities in the registration as to which such withdrawal
         was made.

                  (e) Shareholder may request to have Registrable Securities
         included in an unlimited number of registrations under this Section
         2.1.

         2.2. Demand Rights.

                  (a) Upon written request of the Shareholder made at any time
         (but subject to the limitations on sales of Registrable Securities in
         the Investor Agreement), the Company shall, under the terms and subject
         to the conditions set forth in this Section 2.2, and Sections 2.3 and
         2.4, file (and use its reasonable efforts to cause to become effective)
         a registration statement covering, and use its reasonable efforts to
         qualify for


                                      -4-
<PAGE>   214

         sale under the blue sky or securities laws of the various states of the
         United States as may be requested by the Shareholder (except any such
         state in which, in the opinion of the managing underwriter of the
         offering, the failure to so qualify would not materially and adversely
         affect the proposed offering or in which the Company would be required
         to submit to general jurisdiction to effect such registration), in
         accordance with the intended method or methods of disposition set forth
         in that notice, of such number of Registrable Securities, as may be
         designated by the Shareholder in its request, or that portion thereof
         designated in said request for registration in each of the Designated
         Jurisdictions (as defined below). A request for registration under this
         Section 2.2 shall specify the number of Registrable Securities to be
         registered, the jurisdictions in the United States in which such
         registration is to be effected (the "Designated Jurisdictions") and the
         proposed manner of sale, including the name and address of any proposed
         underwriter. The principal underwriter or underwriters for any such
         offering shall be selected by the Shareholder, subject to the Company's
         approval, which may not be unreasonably withheld or delayed.
         Notwithstanding any other provision in this Section, the Shareholder
         shall not be permitted to make a demand for registration pursuant to
         this Section unless the number of Registrable Securities covered by
         such demand is at least 500,000 shares of Common Stock (or securities
         convertible into such number of shares of Common Stock) (as such number
         may be appropriately adjusted to reflect stock splits, reverse stock
         splits, dividends and any other recapitalization or reorganization of
         the Company) or such lesser number of shares and Notes as would yield
         gross proceeds of not less than $2 million based on the average closing
         price of the Common Stock over the ten trading day period immediately
         preceding the date of the written request hereunder (with the gross
         proceeds of Series B Preferred Stock deemed to be the greater of its
         liquidation preference on the date of such demand and the average
         closing price of the Common Stock into which it is convertible and the
         gross proceeds of debt shall be deemed to be the greater of its
         principal amount and the average closing price of the Common Stock into
         which it is convertible).

                  (b) If the distribution proposed to be effected pursuant to
         this Section 2.2 involves an underwritten offering of Registrable
         Securities and securities of the Company other than Registrable
         Securities ("Other Securities"), and if the managing underwriter of
         such underwritten offering indicates in writing its opinion that
         including all or part of such securities in the coverage of such
         registration statement will materially and adversely affect the sale of
         the securities proposed to be sold, then the number of securities
         proposed to be sold shall be reduced to the maximum number of
         securities (or principal amount) specified by the managing underwriter.
         In such a case, first priority shall be afforded to Registrable
         Securities in accordance with Section 2.1(b) and (c).

                  (c) The Company may delay the filing of any registration
         statement requested under this Section 2.2, or delay its effectiveness,
         for a reasonable period (but not longer than 90 days) if, in the sole
         judgment of the Company's Board of Directors, (i) a delay is necessary
         in light of pending financing transactions, corporate reorganizations
         or other major events involving the Company, or (ii) filing at the time
         requested would materially and adversely affect the business or
         prospects of the Company in view of


                                      -5-
<PAGE>   215

         disclosures that may be thereby required. Once the cause of the delay
         is eliminated, the Company shall promptly notify the Shareholder and,
         promptly after Shareholder notifies the Company to proceed, the Company
         shall file a registration statement and begin performance of its
         remaining obligations under this Section 2.2.

                  (d) The Shareholder shall be entitled to request not more than
         seven registrations under this Section 2.2 (provided that the filing of
         a registration statement in more than one Designated Jurisdiction in
         connection with a concurrent or substantially concurrent distribution
         shall be deemed for the purposes of this Agreement to be a single
         registration). However, if the Shareholder requests a registration
         under this Section 2.2, but no registration statement becomes effective
         with respect to the Registrable Securities covered by such request, or
         any registration statement is withdrawn or prematurely terminated
         (whether pursuant to this Section 2.2 or as a result of any stop order,
         injunction or other order or requirement of the SEC or any other
         governmental agency or court), then such request shall not count as a
         request for purposes of determining the number of requests for
         registration the Shareholder may make under this Section 2.2.

                  (e) If there is an effective registration statement requested
         by the Shareholder pursuant to this Section 2.2, the Shareholder may
         require the Company to delay the filing of any registration statement
         relating to convertible securities or shares of Common Stock or delay
         its effectiveness, for a reasonable period (but not longer than 90
         days) if, in the sole judgment of the Shareholder, a delay is necessary
         in order to avoid materially and adversely affecting the disposition of
         Registrable Securities pursuant to the offering by the Shareholder;
         provided that the foregoing shall not limit the Company's right to file
         and have declared effective registration statements for any other
         offering.

         2.3. Registration Conditions. Notwithstanding any other provision of
this Agreement, the Company shall not be required to effect a registration of
any securities under this Article II, or file any post-effective amendment to
such a registration statement relating to such a qualification:

                  (a) unless Shareholder agrees to (x) sell and distribute a
         portion or all of their Registrable Securities in accordance with the
         plan or plans of distribution adopted by and through underwriters, if
         any, acting for the Company or any such other sellers of Notes, Common
         Stock or Series B Preferred Stock, and (y) bear a pro rata share of
         underwriter's discounts and commissions;

                  (b) if, in the case of a request for registration under
         Section 2.2, the Company has given notice under Section 2.1 of its
         intention to file a registration statement under the Securities Act and
         has not completed or abandoned the proposed offering (for so long as
         the Company continues in good faith to pursue the proposed offering);
         and

                  (c) unless the Company has received from Shareholder all
         information the Company has reasonably requested concerning Shareholder
         and their method of


                                      -6-

         distribution of Registrable Securities, so as to enable the Company to
         include in the registration statement all facts required to be
         disclosed in it.

         2.4. Covenants and Procedures. If the Company becomes obligated under
this Article II to effect a registration of Registrable Securities on behalf of
Shareholder, then (as applicable to the jurisdictions for which such
registration is to be made):

                  (a) The Company, at its expense as provided in Section 4.2,
         shall prepare and file with the SEC a registration statement covering
         such securities and such other related documents as may be necessary or
         appropriate relating to the proposed distribution, and shall use
         reasonable efforts to cause the registration statement to become
         effective. The Company will also, with respect to any registration
         statement, file such post-effective amendments to the registration
         statement (and use reasonable efforts to cause them to become
         effective) and such supplements as are necessary so that current
         prospectuses are at all times available for a period of at least 180
         days after the effective date of the registration statement or for such
         longer period, not to exceed 360 days, as may be required under the
         plan or plans of distribution set forth in the registration statement.
         Shareholder shall promptly provide the Company with such information
         with respect to Shareholder' Registrable Securities to be so registered
         and, if applicable, the proposed terms of their offering, as is
         required for the registration. If the Registrable Securities to be
         covered by the registration statement are not to be sold to or through
         underwriters acting for the Company, the Company shall:

                           (i) deliver to Shareholder, as promptly as
                  practicable, as many copies of preliminary prospectuses as
                  Shareholder may reasonably request (in which case Shareholder
                  shall keep a written record of the distribution of the
                  preliminary prospectuses and shall refrain from delivery of
                  the preliminary prospectuses in any manner or under any
                  circumstances which would violate the Securities Act or the
                  securities laws of any other jurisdiction, including the
                  various states of the United States);

                           (ii) deliver to Shareholder, as soon as practicable
                  after the effective date of the registration statement, and
                  from time to time thereafter during the applicable period
                  described in Section 2.4, as many copies of the relevant
                  prospectus as Shareholder may reasonably request; and

                           (iii) in case of the happening, after the effective
                  date of the registration statement and during the applicable
                  180 or 360-day period described in the second sentence of
                  Section 2.4(a), of any event or occurrence as a result of
                  which the prospectus, as then in effect, would include an
                  untrue statement of a material fact or omit to state any
                  material fact required to be stated therein or necessary to
                  make any statement therein not misleading in the light of the
                  circumstances in which it was made, give Shareholder written
                  notice of the event or occurrence and prepare and furnish to
                  Shareholder, in such quantities as it may reasonably request,
                  copies of an amendment of or a supplement to such


                                      -7-
<PAGE>   217

                  prospectus as may be necessary so that the prospectus, as so
                  amended or supplemented and thereafter delivered to purchasers
                  of the Registrable Securities covered by such prospectus, will
                  not contain any untrue statement of a material fact or omit to
                  state any material fact required to be stated therein or
                  necessary to make the statements therein, in the light of the
                  circumstances under which it was made, not misleading.

                  (b) The Company will notify Shareholder of any action by the
         SEC or any Commission to suspend the effectiveness of any registration
         statement filed pursuant hereto or the initiation or threatened
         initiation of any proceeding for such purpose or the receipt by the
         Company of any notification with respect to the suspension of the
         qualification of the securities for sale in any jurisdiction.
         Immediately upon receipt of any such notice, Shareholder shall cease to
         offer or sell any Registrable Securities pursuant to the registration
         statement or prospectus in the jurisdiction to which such order or
         suspension relates. The Company will also notify Shareholder promptly
         of the occurrence of any event or the existence of any state of facts
         that, in the judgment of the Company, should be set forth in such
         registration statement or prospectus. Immediately upon receipt of such
         notice, Shareholder shall cease to offer or sell any Registrable
         Securities pursuant to such registration statement or prospectus, cease
         to deliver or use such registration statement or prospectus and, if so
         requested by the Company, return to the Company at the Company's
         expense all copies of such registration statement or prospectus. The
         Company will as promptly as practicable take such action as may be
         necessary to amend or supplement such registration statement or
         prospectus in order to set forth or reflect such event or state of
         facts and provide copies of such proposed amendment or supplement to
         Shareholder.

                  (c) On or before the date on which the registration statement
         is declared effective, the Company shall use its reasonable efforts to:

                           (i) register or qualify (and cooperate with
                  Shareholder, the underwriter or underwriters, if any, and
                  their counsel, in connection with the registration or
                  qualification of) the securities covered by the registration
                  statement for offer and sale under the securities or blue sky
                  laws of each state and other jurisdiction as Shareholder or
                  any underwriter reasonably requests;

                           (ii) keep each such registration or qualification
                  effective, including through new filings, or amendments or
                  renewals, during the period the registration statement or
                  prospectus is required to be kept effective; and

                           (iii) do any and all other acts or things necessary
                  or advisable to enable the disposition in all such
                  jurisdictions of the Registrable Securities covered by the
                  applicable registration statement, provided that the Company
                  will not be required to qualify generally to do business in
                  any jurisdiction where it is not then so qualified.


                                      -8-
<PAGE>   218

                  (d) The Company shall use its reasonable efforts to cause all
         Registrable Securities of Shareholder included in the registration
         statement to be listed, by the date of the first sale of such shares
         pursuant to such registration statement, on the NASDAQ NMS or each
         securities exchange on which the securities are then listed or proposed
         to be listed, if any, as directed by the Shareholder (subject to the
         Company's consent, which consent shall not be unreasonably withheld or
         delayed).

                  (e) The Company shall make available to Shareholder and any
         underwriter participating in the offering conducted pursuant to the
         registration statement an earnings statement satisfying Section 11(a)
         of the Securities Act no later than 45 days after the end of the
         12-month period beginning with the first day of the Company's first
         fiscal quarter commencing after the effective date of the registration
         statement. The earnings statement shall cover such 12-month period.
         This requirement will be deemed to be satisfied if the Company timely
         files complete and accurate information on Forms 10-Q, 10-K, and 8-K
         under the Exchange Act, and otherwise complies with Rule 158 under the
         Securities Act as soon as feasible.

                  (f) The Company shall cooperate with Shareholder and the
         managing underwriter or underwriters, if any, to facilitate the timely
         preparation and delivery of certificates (not bearing any restrictive
         legends) representing Registrable Securities to be sold under the
         registration statement, and to enable such securities to be in such
         denominations and registered in such names as the managing underwriter
         or underwriters, if any, or Shareholder, may request, subject to the
         underwriters' obligation to return any certificates representing unsold
         securities.

                  (g) The Company shall use its reasonable efforts to cause
         Registrable Securities covered by the registration statement to be
         registered with or approved by such other governmental agencies or
         authorities in the United States (including the registration of
         Registrable Securities under the Exchange Act) as may be necessary to
         enable Shareholder or the underwriter or underwriters, if any, to
         consummate the disposition of such securities.

                  (h) The Company shall, during normal business hours and upon
         reasonable notice, make available for inspection by Shareholder, any
         underwriter participating in any offering pursuant to the registration
         statement, and any attorney, accountant or other agent retained by
         Shareholder or any such underwriter (collectively, the "Inspectors"),
         all financial and other records, pertinent corporate documents, and
         properties of the Company (including non-public information), as shall
         be reasonably necessary to enable the Inspectors to exercise their due
         diligence responsibilities; provided that any Inspector receiving
         non-public information shall have previously entered into an
         appropriate confidentiality agreement in mutually satisfactory form and
         substance. The Company shall also cause its officers, directors, and
         employees to supply all information reasonably requested by any
         Inspector in connection with the registration statement.


                                      -9-
<PAGE>   219

                  (i) The Company shall use its reasonable efforts to obtain a
         "cold comfort" letter and, as applicable, a "long-form comfort letter"
         from the Company's independent public accountants, and an opinion of
         counsel for the Company, each in customary form and covering such
         matters of the type customarily covered by cold comfort letters and
         long form comfort letters and legal opinions in connection with public
         offerings of securities, as Shareholder reasonably request.

                  (j) The Company shall enter into such customary agreements
         (including an underwriting agreement containing such representations
         and warranties by the Company and such other terms and provisions, as
         are customarily contained in underwriting agreements for comparable
         offerings and are reasonably satisfactory to the Company) and take all
         such other actions as Shareholder or the underwriters participating in
         such offering and sale may reasonably request in order to expedite or
         facilitate such offering and sale (other than such actions which are
         disruptive to the Company or require significant management
         availability), including providing reasonable availability of
         appropriate members of senior management of the Company to provide
         customary due diligence assistance in connection with any offering and
         to participate in customary "road show" presentations in connection
         with any underwritten offerings in substantially the same manner as
         they would in an underwritten primary registered public offering by the
         Company of its Common Stock, after taking into account the reasonable
         business requirements of the Company in determining the scheduling and
         duration of any road show.

                                   ARTICLE III

                                 INDEMNIFICATION

         3.1. Indemnification by the Company. In the event of any registration
under the Securities Act by any registration statement pursuant to rights
granted in this Agreement of Registrable Securities held by Shareholder, the
Company will hold harmless Shareholder and each underwriter of such securities
and each other person, if any, who controls any Shareholder or such underwriter
within the meaning of the Securities Act, against any losses, claims, damages,
or liabilities (including legal fees and costs of court), joint or several, to
which Shareholder or such underwriter or controlling person may become subject
under the Securities Act or otherwise, insofar as such losses, claims, damages,
or liabilities (or any actions in respect thereof) arise out of or are based
upon any untrue statement or alleged untrue statement of any material fact (i)
contained, on its effective date, in any registration statement under which such
securities were registered under the Securities Act or any amendment or
supplement to any of the foregoing, or which arise out of or are based upon the
omission or alleged omission to state a material fact required to be stated
therein or necessary to make the statements therein not misleading or (ii)
contained in any preliminary prospectus, if used prior to the effective date of
such registration statement, or in the final prospectus (as amended or
supplemented if the Company shall have filed with the SEC any amendment or
supplement to the final prospectus) if used within the period which the Company
is required to keep the registration to which such registration statement or
prospectus relates current under Section 2.4, or which arise out of or are


                                      -10-
<PAGE>   220

based upon the omission or alleged omission (if so used) to state a material
fact required to be stated in such prospectus or necessary to make the
statements in such prospectus not misleading; and will reimburse Shareholder and
each such underwriter and each such controlling person for any legal or any
other expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, or liability; provided, however, that
the Company shall not be liable to any Shareholder or its underwriters or
controlling persons in any such case to the extent that any such loss, claim,
damage, or liability arises out of or is based upon an untrue statement or
alleged untrue statement or omission or alleged omission made in such
registration statement or such amendment or supplement, in reliance upon and in
conformity with information furnished to the Company through a written
instrument duly executed by Shareholder or such underwriter specifically for use
in the preparation thereof.

         3.2. Indemnification by Shareholder. It shall be a condition precedent
to the obligation of the Company to include in any registration statement any
Registrable Securities of Shareholder that the Company shall have received from
Shareholder an undertaking, reasonably satisfactory to the Company and its
counsel, to indemnify and hold harmless (in the same manner and to the same
extent as set forth in Section 3.1) the Company, each director of the Company,
each officer of the Company who shall sign the registration statement, and any
person who controls the Company within the meaning of the Securities Act, (i)
with respect to any statement or omission from such registration statement, or
any amendment or supplement to it, if such statement or omission was made in
reliance upon and in conformity with information furnished to the Company
through a written instrument duly executed by Shareholder specifically for use
in the preparation of such registration statement or amendment or supplement,
and (ii) with respect to compliance by Shareholder with applicable laws in
effecting the sale or other disposition of the securities covered by such
registration statement.

         3.3 Indemnification Procedures. Promptly after receipt by an
indemnified party of notice of the commencement of any action involving a claim
referred to in the preceding Sections of this Article III, the indemnified party
will, if a resulting claim is to be made or may be made against an indemnifying
party, give written notice to the indemnifying party of the commencement of the
action. If any such action is brought against an indemnified party, the
indemnifying party will be entitled to participate in and to assume the defense
of the action with counsel reasonably satisfactory to the indemnified party, and
after notice from the indemnifying party to such indemnified party of its
election to assume defense of the action, the indemnifying party will not be
liable to such indemnified party for any legal or other expenses incurred by the
latter in connection with the action's defense. An indemnified party shall have
the right to employ separate counsel in any action or proceeding and participate
in the defense thereof, but the fees and expenses of such counsel shall be at
such indemnified party's expense unless (a) the employment of such counsel has
been specifically authorized in writing by the indemnifying party, which
authorization shall not be unreasonably withheld, (ii) the indemnifying party
has not assumed the defense and employed counsel reasonably satisfactory to the
indemnified party within 30 days after notice of any such action or proceeding,
or (iii) the named parties to any such action or proceeding (including any
impleaded parties) include the indemnified party and the indemnifying party and
the indemnified party shall have been advised by such counsel that there may be
one or more legal defenses available to the indemnified party that are different
from


                                      -11-
<PAGE>   221

or additional to those available to the indemnifying party (in which case the
indemnifying party shall not have the right to assume the defense of such action
or proceeding on behalf of the indemnified party), it being understood, however,
that the indemnifying party shall not, in connection with any one such action or
separate but substantially similar or related actions in the same jurisdiction
arising out of the same general allegations or circumstances, be liable for the
reasonable fees and expenses of more than one separate firm of attorneys (in
addition to all local counsel which is necessary, in the good faith opinion of
both counsel for the indemnifying party and counsel for the indemnified party in
order to adequately represent the indemnified parties) for the indemnified party
and that all such fees and expenses shall be reimbursed as they are incurred
upon written request and presentation of invoices. Whether or not a defense is
assumed by the indemnifying party, the indemnifying party will not be subject to
any liability for any settlement made without its consent. No indemnifying party
will consent to entry of any judgment or enter into any settlement which does
not include as an unconditional term the giving by the claimant or plaintiff, to
the indemnified party, of a release from all liability in respect of such claim
or litigation.

         3.4. Contribution. If the indemnification required by this Article III
from the indemnifying party is unavailable to or insufficient to hold harmless
an indemnified party in respect of any indemnifiable losses, claims, damages,
liabilities, or expenses, then the indemnifying party shall contribute to the
amount paid or payable by the indemnified party as a result of such losses,
claims, damages, liabilities, or expenses in such proportion as is appropriate
to reflect (i) the relative benefit of the indemnifying and indemnified parties
and (ii) if the allocation in clause (i) is not permitted by applicable law, in
such proportion as is appropriate to reflect the relative benefit referred to in
clause (i) and also the relative fault of the indemnified and indemnifying
parties, in connection with the actions which resulted in such losses, claims,
damages, liabilities, or expenses, as well as any other relevant equitable
considerations. The relative fault of the indemnifying party and the indemnified
party shall be determined by reference to, among other things, whether any
action in question, including any untrue or alleged untrue statement of a
material fact, has been made by, or relates to information supplied by, such
indemnifying party or parties, and the parties' relative intent, knowledge,
access to information, and opportunity to correct or prevent such action. The
amount paid or payable by a party as a result of the losses, claims, damage,
liabilities, and expenses referred to above shall be deemed to include any legal
or other fees or expenses reasonably incurred by such party in connection with
any investigation or proceeding. The Company and Shareholder agree that it would
not be just and equitable if contribution pursuant to this Section 3.4 were
determined by pro rata allocation or by any other method of allocation which
does not take account of the equitable considerations referred to in the prior
provisions of this Section 3.4.

         Notwithstanding the provisions of this Section 3.4, no indemnifying
party shall be required to contribute any amount in excess of the amount by
which the total price at which the securities were offered to the public by the
indemnifying party exceeds the amount of any damages which the indemnifying
party has otherwise been required to pay by reason of an untrue statement or
omission. No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Securities Act) shall be entitled to contribution from
any person who was not guilty of such a fraudulent misrepresentation.

                                   ARTICLE IV

                                OTHER AGREEMENTS

         4.1. Other Registration Rights. The Company agrees that it will not
grant to any party registration rights which would allow such party to limit
Shareholder' priority for the sale or distribution of Registrable Securities
upon the exercise of a demand registration right pursuant to Section 2.2 or
incidental registration rights pursuant to Section 2.1.

         4.2. Expenses. All expenses incurred by the Company in connection with
any registration statement covering Registrable Securities offered by
Shareholder, including, without limitation, all registration and filing fees
(including all expenses incident to filing with the National Association of
Securities Dealers, Inc.), printing expenses, reasonable fees and disbursements
of counsel (except for the fees and disbursements of counsel for Shareholder)
and of the independent certified public accountants, underwriter's reasonable
legal, accounting and out-of-pocket expenses, and the expense of qualifying such
securities under state blue sky laws, shall be borne by the Company, including
such expenses of any registration delayed by the Company under the fourth
paragraph of Section 2.2; provided, however, that the Company shall not be
required to pay for any expenses of any registration proceeding begun pursuant
to Section 2.2 if the registration request is subsequently withdrawn at the
request of the Shareholder (in which case the Shareholder shall bear such
expenses, each such Shareholder to bear its pro rata share of the expense based
on the number of Registrable Securities such Shareholder intended to include in
such registration compared to the total number of Registrable Securities all of
such Shareholder intended to include in such registration), unless the
Shareholder agrees to forfeit its right to one demand registration under Section
2.2; provided further, however, that if at the time of such withdrawal, the
Shareholder have learned of a material adverse change in the condition,
business, or prospects of the Company from that known at the time of its
request, then the Shareholder shall not be required to pay any of such expenses
and shall retain their rights pursuant to Section 2.2. The Company's obligations
under this Section 4.2 shall apply to each registration under the Securities Act
or state blue sky legislation pursuant to Section 2.2. However, all
underwriter's discounts and commissions covering Registrable Securities offered
by Shareholder shall be borne by Shareholder.

         4.3. Dispositions During Registration. Each Shareholder agrees that,
without the consent of the managing underwriter(s) in an underwritten offering
in respect of Common Stock or other Subject Securities, it will not effect any
sale or distribution of Common Stock or other Subject Securities (other than
Registrable Securities included in such offering), during the ten (10) day
period prior to, and during the ninety (90) day period beginning on, the
effective date of the registration statement filed by the Company in respect of
such underwritten offering, or any shorter period as may apply to the Company
and its affiliates.

         4.4. Transfer of Rights. All rights of Shareholder under this Agreement
shall be transferable by Shareholder to any party who acquires Registrable
Securities in compliance with the Investor Agreement and who executes an
instrument in form and substance satisfactory to the Company in which it agrees
to be bound by the terms of this Agreement as if an original


                                      -13-
<PAGE>   223

signatory hereto, in which case such transferee shall thereafter be a
"Shareholder" for all purposes of this Agreement. In the case of any assignment,
the party or parties who have the rights and benefits of Shareholder under this
Agreement shall become parties to and be subject to this Agreement, and shall
not, as a group, have the right to request any greater number of registrations
than Shareholder would have had if no assignment had occurred. Upon any transfer
of the registration rights or benefits of this Agreement, Shareholder shall give
the Company written notice prior to or promptly following such transfer stating
the name and address of the transferee and identifying the securities with
respect to which such rights are being assigned. Such notice shall include or be
accompanied by a written undertaking by the transferee to comply with the
obligations imposed hereunder. Unless otherwise agreed by Shareholder and the
parties to whom registration rights have been transferred, in the event any
registration rights are transferred in accordance with the terms of this
Agreement, any actions required to be taken by Shareholder will be taken with
the approval of the holders of such registration rights who hold a majority of
the Registrable Securities, whose actions shall bind all such holders of such
registration rights.

         4.5. Best Registration Rights. If the Company grants to any Person with
respect to any security issued by the Company or any of its Affiliates
registration rights (other than as to the number of demand registrations) that
provide for terms that are in any manner more favorable to the holder of such
registration rights than the terms granted to the Shareholder (or if the Company
amends or waives any provision of any agreement providing registration rights of
others or takes any other action whatsoever to provide for terms that are more
favorable to other holders than the terms provided to the Shareholder other than
the number of demand registrations or the minimum amount of shares required to
exercise demand registration rights), then this Agreement shall immediately be
deemed amended to provide the Shareholder with any (or all) of such more
favorable terms as Shareholder shall elect to include herein. The Company shall
promptly give notice to the Shareholder of the granting of any such registration
rights to another Person.

                             STOCKHOLDERS AGREEMENT

         THIS STOCKHOLDERS AGREEMENT (the "AGREEMENT"), dated as of August 31,
2000, by and among Thomas F. Hewitt, J. William Richardson and Kevin P. Kilkeary
(each a "STOCKHOLDER" and together the "STOCKHOLDERS") and CGLH Partners I LP
and CGLH Partners II LP, each a Delaware limited partnership (together the
"INVESTOR").

                                   WITNESSETH

         WHEREAS, contemporaneously with the execution hereof, Interstate Hotels
Corporation, a Maryland corporation (the "COMPANY"), is entering into an amended
and restated employment agreement with each of the Stockholders pursuant to
which each Stockholder shall become, upon the closing of the transactions
contemplated by the Securities Purchase Agreement to be entered into between the
Company and the Investor (the "PURCHASE AGREEMENT"), the record holder of the
number of shares of Series B Convertible Preferred Stock, par value $.01 per
share (the "SERIES B PREFERRED STOCK") set forth beside such Stockholder's name
below, and which Series B Preferred Stock shall vest over time; and

         WHEREAS the Stockholders and the Investors desire to enter into certain
agreements with each of the Stockholders with respect to the Series B Preferred
Stock to be granted to the Stockholders.

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants and obligations herein set forth, the parties agree as follows:

         Section 1. Irrevocable Proxy. Each Stockholder as the record holder and
beneficial owner of the below indicated shares of Series B Preferred Stock,
hereby revokes all previous proxies and appoints CGLH Partners III LP, a
Delaware limited partnership, as representative of the Investor, as the true and
lawful proxy and attorney-in-fact for the undersigned to vote on any and all
matters at any annual or special meeting of the holders of Series B Preferred
Stock and to exercise any and all rights to execute written consent or approval
and any similar right granted to all of the below indicated shares of Series B
Preferred Stock of such Stockholder and all of the shares of Series B Preferred
Stock hereafter acquired by such Stockholder pursuant to Section 2(a) of the
Articles Supplementary to the Charter of the Company designating the Series B
Preferred Stock (together such "STOCKHOLDER'S SHARES").

         Each Stockholder authorizes and directs the proxy holder to file this
proxy with the Secretary of the Company and authorizes the proxy holder, and any
subsequent proxy holder, to substitute another person as proxy holder and to
file the substitution instrument with the Secretary of the Company.

         This proxy is irrevocable and is coupled with an interest in that it is
given in consideration of the agreements herein between each Stockholder and the
Investor, and is being delivered as an inducement for the Investor to allow such
Stockholder to participate with the




<PAGE>   230



Company and affiliates of the Investor in an investment partnership. As such
this proxy may not be revoked without the written consent of the Investor. Each
Stockholder agrees not to attempt to vote such Stockholder's Shares, execute
consents in respect thereof or grant proxies or assign rights to vote with
respect to such Stockholder's Shares to any other party

         Section 2. Tag-Along Rights. (a) Subject to Section 2(d) below in the
event that the Investor proposes to Sell (a "DISPOSITION") any Series B
Preferred Stock to a person other than an affiliate or associate of the Investor
or a Related Transferee (as such term is defined in the Investor Agreement,
which appears as Exhibit C to the Securities Purchase Agreement) and other than
to the Stockholders (a "PURCHASER"), in any private sale or any registered
public offering, then the Investor shall provide notice (a "PROPOSAL NOTICE") of
such proposed Disposition to each of the Stockholders no later than five (5)
days prior to the proposed closing of such Disposition. Each Proposal Notice
shall describe in reasonable detail the terms of the proposed Disposition,
including, without limitation, (i) the identity and address of the Purchaser,
(ii) the number of shares of Series B Preferred Stock proposed to be Sold by the
Investor (the "SALE STOCK"), (iii) the proposed amount and form of consideration
to be paid by the Purchaser to the Investor and (iv) any other material terms or
conditions of such proposed Disposition, and shall include a statement to the
effect that the Purchaser has been informed of the Tag-Along Rights (as defined
herein) and an acknowledgment by the Purchaser indicating that it has been so
informed and agrees to such terms. A copy of the Proposal Notice shall promptly
be sent to the Company.

                  (b) Subject to Sections 2(c) and 2(d) below, with respect to
each proposed Disposition each Stockholder shall have the right (the "TAG-ALONG
RIGHT") to require the Purchaser to purchase from such Stockholder and at the
Price Per Share (as defined below) all or a portion of the number of shares of
Series B Preferred Stock which represents the number of shares of Series B
Preferred Stock obtained by multiplying (A) a fraction, the numerator of which
is the number of shares of Sale Stock and the denominator of which is the number
of shares of Series B Preferred Stock Beneficially Owned by the Investor and any
Group of which it is a member as of the date of the Proposal Notice, times (B)
the number of shares of Series B Preferred Stock Beneficially Owned by such
Stockholder as of the date of the Proposal Notice.

                  (c) If the Purchaser declines to purchase all of the shares of
Series B Preferred Stock of the Investor and the Stockholders to be sold
pursuant to Section 2(b) hereof, each Stockholder shall have the right to
require the Purchaser to purchase from such Stockholder and at the Price Per
Share all or a portion of the number of shares of Series B Preferred Stock equal
to the number obtained by multiplying (A) a fraction, the numerator of which is
the number of shares of Series B Preferred Stock represented by the Sale Stock
and the denominator of which is the number of shares of Series B Preferred Stock
Beneficially Owned by the Investor and any Group of which it is a member and the
Stockholders as of the date of the Proposal Notice, times (B) the number of
shares of Series B Preferred Stock Beneficially Owned by the Stockholder as of
the date of the Proposal Notice. The number of shares sold by the Investor shall
be reduced to the extent any of the Stockholders choose to exercise their rights
under this Section 2(c).

<PAGE>   231

                  (d) To exercise his Tag-Along Right such Stockholder shall
provide to the Investor written notice of his election to exercise such right
(an "ACCEPTANCE") no later than three (3) days after his receipt of a Proposal
Notice (such three day period, the "ACCEPTANCE PERIOD"). After the lapse of the
Acceptance Period within which the Investor shall not have received an
Acceptance from the Stockholder, the Investor may consummate, without the
participation of the Stockholder, a Sale to one or more purchasers, for
consideration equal to or less than the purchase price specified in the Proposal
Notice and on terms no more favorable to the Investor than those specified in
the Proposal Notice.

                  (e) All Sales of shares of Series B Preferred Stock to the
Purchaser by any Stockholder shall be on the same terms, including
representations, warranties and covenants, as apply to the Investor in respect
of the Sale of the Sale Stock.

                  (f) For purposes of this Agreement:

                  (i) "PER SHARE PRICE" means an amount equal to the quotient
obtained by dividing (A) the aggregate purchase price to be paid by the
Purchaser in respect of the Sale Stock by (B) the number of shares of Sale
Stock;

                  (ii) "SELL" means to sell, or in any other way directly or
indirectly transfer, assign, distribute, pledge, encumber or otherwise dispose
of, either voluntarily or involuntarily, and the terms "SALE," "SELLING" and
"SOLD" shall have meanings correlative to the foregoing; and

                  (iii) "GROUP" has the meaning as such term is used in Rule
13(d) of the Rules under the Securities Exchange Act of 1934.

         Section 3. Drag-Along Rights. (a) If the Investor proposes to Sell to
any person or group of persons (other than an affiliate of the Investor or a
Related Transferee and other than the Stockholders) (collectively, a "BUYER"),
in a bona fide arm's-length transaction or series of transactions, including by
way of a purchase agreement, tender offer, merger or other business combination
transaction or otherwise, 10% or more (such percentage the "SALE PERCENTAGE") of
the shares of Series B Preferred Stock beneficially owned by the Investor and
any Group of which it is a member (any such transaction being referred to herein
as a "MAJOR Sale"), then the Investor may elect to require each Stockholder to
Sell the Sale Percentage of shares of Series B Preferred Stock beneficially
owned by such Stockholder concurrently with such Major Sale to such Buyer at the
purchase price per share, and upon the terms and conditions of, and with the
same representations, warranties and covenants as apply to the Investor in, the
Major Sale.

                  (b) The rights set forth in this Section 3(a) shall be
exercised by giving notice (the "SECTION 3 NOTICE") to each Stockholder setting
forth in detail the terms of the proposed Sale, including without limitation,
(i) the identity and address of the Buyer, (ii) the number of shares of Series B
Preferred Stock proposed to be Sold by the Investor (the "SALE STOCK"), (iii)
the proposed amount and form of consideration to be paid by the Buyer to the
Investor and (iv) any other material terms or conditions of such proposed
Disposition, and shall include a



                                      -3-
<PAGE>   232


statement to the effect that the Buyer has been informed of the Drag-Along
Rights (as defined herein) and an acknowledgment by the Buyer indicating that it
has been so informed and agrees to such terms, and (vi) the proposed closing
date of the Major Sale, which proposed date (the "SECTION 3 CLOSING DATE") shall
be the later of (A) a business day not less than 15 or more than 60 days after
such Section 3 Notice is delivered to the Stockholders or (B) the fifth business
day following the receipt of all regulatory or third party consents and
approvals, if any, applicable to such Sale.

                  (c) Each Stockholder will (i) take all such actions as may be
requested by Investor to carry out the purposes of this Section 3, and (ii)
execute all documents containing such terms and conditions, including, without
limitation, representations and warranties with respect to (x) matters of title
to such Stockholder's securities and (y) the due authorization (or capacity) and
due and valid execution and delivery by such Stockholder of documentation in
respect of the Major Sale, as those executed by the Investor, and shall execute
and deliver such other instruments and agreements as may be requested by the
Investor. Each Stockholder shall be severally obligated to join on a pro-rata
basis (based on such Shareholder's share of the aggregate proceeds paid in such
Major Sale) in any indemnification that is to be provided in connection with
such Major Sale, other than any such indemnification that relates specifically
to a particular Stockholder, such as indemnification with respect to
representations and warranties given by an Stockholder regarding such
Stockholder's title to and ownership of shares of Series B Preferred Stock or
valid authorization by such Stockholder with respect to such Major Sale.

                  Section 4. Purchase upon Termination.At any time after the
termination of any Stockholder's employment with the Company the Investor shall
have the right (but not the obligation) to acquire all of such Stockholder's
Shares (the "PURCHASE INTEREST"), for an amount equal to the fair market value
of such Purchase Interest as of the Purchase Interest Closing Date. The
following procedure shall apply to such proposed acquisition:

                  (a) The Investor shall give notice (the "PURCHASE NOTICE") to
such Stockholder specifying the fair market value for such Stockholder's
Purchase Interest as of the date of such Purchase Notice, determined by the
Investor in good faith. For a period of 10 days after the Purchase Notice has
been given, the Investor and such Stockholder shall negotiate in good faith to
mutually agree on such fair market value (the "PURCHASE PRICE").

                  (b) On a date mutually agreed by the Investor and the
Stockholder, but in no event later than 20 days after the Purchase Notice has
been given (such date, the "PURCHASE CLOSING DATE"), the Investor shall pay to
the Stockholder the Purchase Price against the delivery of certificates or other
instruments evidencing such shares of Series B Preferred Stock duly endorsed for
transfer.

                  (c) Any dispute as to the fair market value of the Purchase
Interest shall be submitted for final determination to a mutually acceptable
investment banking firm of national reputation familiar with the valuation of
companies in the hospitality and lodging industry (an



                                      -4-
<PAGE>   233



"INVESTMENT BANKING FIRM"). In the event that the Investor and the Stockholder
cannot agree on a mutually acceptable Investment Banking Firm within 10 business
days, the Investor, on the one hand, and the Stockholder, on the other hand,
shall each select one Investment Banking Firm, which two Investment Banking
Firms shall jointly make such determination within 20 business days after the
date of the Purchase Notice, or, if such two Investment Banking Firms are unable
to agree on such determination, the two Investment Banking Firms shall, by the
end of the 20th business day after the date of the Purchase Notice, select a
third Investment Banking Firm and notify such third Investment Banking Firm in
writing (with a copy to the Investor and the Stockholder) of their respective
determinations of the fair market value of the Purchase Interest following which
such third Investment Banking Firm shall, within 15 business days after the date
of its selection, notify the Investor and the Stockholder in writing of its
selection of one or the other of the two original determinations of the fair
market value of the Purchase Interest, which determination shall be final and
binding on the Investor and the Stockholder. The costs of the Investment Banking
Firms shall be borne by the Investor.

                  Section 5. Notices.Any notice required or permitted to be
given or made to a person under this Agreement shall be in writing and shall be
deemed given or made: (i) when delivered in person, by overnight mail using a
