Purchase Agreement (the "Kahler Stock Purchase Agreement"), dated as of August
5, 1997, among the Issuer, WREF I, WRECIP I and Kahler Realty Corporation, a
Minnesota corporation ("Kahler") attached hereto as Exhibit 2. Pursuant to the

Item 4.  Purpose of Transaction.

                  WREF I and WRECIP I acquired the Issuer's securities for
investment purposes. The acquisition of the 2,284,262 shares of Issuer Common
Stock and the 250,000 shares of Issuer Preferred Stock was made pursuant to the
terms of the Kahler Stock Purchase Agreement.

                  Pursuant to the terms of the Kahler Stock Purchase Agreement,
the Issuer increased the size of its Board of Directors from 8 to 9 directors
and caused Kazilionis to be designated as a member of its Board of Directors

long as WREF I and WRECIP I continue to beneficially own at least 33-1/3% of the

designate for nomination as a director of the Issuer as part of the Issuer's
management slate that number of directors equal to the product of the percentage
of outstanding Issuer

Common Stock beneficially owned by WREF I and WRECIP I (on a fully diluted
basis) multiplied by the number of directors on the Board of Directors of the
Issuer. The Issuer has agreed to provide the same type of support for the
election of the designees of WREF I and WRECIP I as directors of the Issuer that
its affiliates and management provide to persons standing for election as

                  Pursuant to the Articles Supplementary of the Articles of
Incorporation of the Issuer which relate to the Issuer Preferred Stock (as

I and WRECIP I may convert their holdings of Issuer Preferred Stock into shares
of Issuer Common Stock at any time after issuance of the Issuer Preferred Stock
and prior to the fifth day prior to the date set for the redemption of such
Issuer Preferred Stock in whole or in part or the closing of any transaction
involving the liquidation, dissolution or winding up of the Issuer. The number
of shares of Issuer Common Stock issued upon such conversion will be equal to
the Original Series A Issue Price (as defined in the Articles Supplementary), as
adjusted (currently $100), divided by the Conversion Price (as defined in the
Articles Supplementary) applicable to each share of Issuer Preferred Stock, as
adjusted (currently $14.7093). The Original Series A Issue Price and the
Conversion Price are to be adjusted to take into account any stock dividends,
combinations, splits or similar events with respect to the Issuer Common Stock
or Issuer Preferred Stock.

                  In addition, pursuant to the Articles Supplementary, the
holders of the Issuer Preferred Stock have the right, upon the occurrence of

                                   ARTICLE I

                   THE PURCHASE AND SALE OF STOCK AND NOTES

            SECTION 1.1 General. Upon the terms and subject to the conditions
set forth in this Agreement, the Funds shall sell to the Purchaser, and the
Purchaser shall purchase from the Funds, the Stock and Notes at the Closing (as
hereinafter defined). The consideration for the Stock and the Notes shall be
paid as provided in Section 1.3.

            SECTION 1.2 Closing. Unless this Agreement shall have been
terminated and the transactions herein contemplated shall have been abandoned
pursuant to Section 6.1, and subject to the satisfaction or waiver of the
conditions set forth in Article V, the closing of the Stock Purchase and the
Notes Purchase (the "Closing") shall take place on the later of (i) October 15,
1997 (or such earlier date as the Purchaser may designate at its discretion on
at least two business days' prior written notice to the Funds) and (ii) the date
which is two business days following satisfaction or waiver of the conditions
set forth in Article V (other than with respect to actions to take place on the
date of Closing or the day preceding the date of Closing) at the offices of
Brobeck, Phleger & Harrison, 4675 MacArthur Court, Suite 1000, Newport Beach,
California 92660, unless another date, time or place is agreed to in writing by
the parties hereto; provided that in the event the condition precedents set
forth in Article V are satisfied on or after October 15, 1997 but the Purchaser
does not yet have available all necessary financing to consummate the Closing,
the Purchaser may specify that the Closing Date will occur on the first date
that all such financing is available (but in no event shall such date be later
than December 23, 1997) provided that the Purchaser has been using, and
continues to use, reasonable best efforts to obtain such financing at the
earliest practicable date and the Purchaser delivers to the Funds (x) a letter
from Bank One of Arizona confirming that its commitment remains in full force
and effect and unmodified in any material respect or written financial
commitments in form and substance reasonably acceptable to the Funds from other
financial institutions reasonably acceptable to the Funds with respect to the
financing contemplated by the Bank One of Arizona Commitment and (y) written
financing commitments in form and substance reasonably acceptable to the Funds
from Merrill Lynch & Co. or from other financial institutions reasonably
acceptable to the Funds with respect to all equity and other financing that is
required to consummate the transactions contemplated by this Agreement. The
actual date and time of the Closing are referred to herein as the "Closing
Date."

            SECTION 1.3       Consideration.

            (a) General. (i) The consideration for the Stock shall consist of:
(i) $94,680,000 in cash (the "Cash Consideration"); provided, however, that the
amount payable pursuant to this clause (i) shall be reduced by an amount equal
to the sum of the accumulated earnings and profits through the Closing Date as
determined pursuant to Section 1.4 (for purposes of this Section 1.3(a), the
accumulated earnings and profits as determined pursuant to Section 1.4 shall not
be reduced by any distributions made after the date of this Agreement), plus
$250,000; provided further, that if the Closing has not occurred on or before
October 15, 1997, the amount

                                                                               3


of cash payable to the Funds at Closing shall be increased by an amount equal to
a 10% per annum return on $151,680,000 for the period beginning on (and
including) October 16, 1997 through (but excluding) the Closing Date (it being
understood, however, that if the Closing Date is October 16, 1997, the
consideration payable will be increased by one day's return) which return shall
be computed on the basis of a 365-day year and for the actual number of days
elapsed in the period during which it accrues, (ii) 2,284,262 shares (the
"Purchaser Common Stock Consideration") of common stock, par value $.01 per
share, of the Purchaser (the "Purchaser Common Stock"); provided, however, that
if, after the date of this Agreement and prior to the Closing Date, (x) the
issued and outstanding shares of Purchaser Common Stock shall have been changed,
or a record date shall have been set for a change of such issued and outstanding
shares, into a different number of shares or a different class by reason of any
stock dividend, subdivision, reclassification, recapitalization, split,
combination, exchange of shares or otherwise, the Purchaser Common Stock
Consideration shall be correspondingly adjusted to reflect such change or (y)
the Purchaser shall effect a merger, consolidation or other business
combination, then at the Closing the Funds shall be entitled to receive such
consideration under this clause (ii) as the Funds would have received in such
merger, consolidation or other business combination had the Funds owned the
Purchaser Common Stock Consideration at the time of such transaction (iii)
250,000 shares (the "Purchaser Convertible Preferred Stock Consideration" and
collectively with the Cash Consideration and Purchaser Common Stock
Consideration, the "Stock Purchase Consideration") of convertible preferred
stock, par value $.01 per share, of the Purchaser (the "Purchaser Convertible
Preferred Stock") having the powers, preferences, and other rights set forth in
the articles supplementary attached hereto as Exhibit 1.3 (the "Certificate of

certificate from the Purchaser, signed on behalf of the Purchaser by its chief
financial officer, stating that all conditions set forth in Article V (other

the conditions set forth in Article V are or will be satisfied within two days,
prior to the Closing the Company and its Subsidiaries will be restructured in
the manner identified in Steps 1 through 4 of Schedule 1.5 (the "Pre-Closing
Restructuring"). The specific legal steps required to effect the Restructuring

preparation of all documentation and making all necessary legal arrangements to
effect the Pre-Closing Restructuring, except for any expenses or costs which the
Funds are expressly required to pay under this Agreement relating to the Stock
Purchase and in connection with obtaining any Required Consent. The Purchaser

Company a reasonable opportunity to review and comment on, all documentation and
other arrangements relating to the Pre-Closing Restructuring and the Pre-Closing
Restructuring will be effected in a manner that does not impose any tax or other
liability or obligation of any nature on the Funds. The Funds, the Company, and

Company's Investment Entities, shall cooperate with the Purchaser in connection
with the matters contemplated by this Section 1.5. The Company and the

prior to the first day of the Trading Period the Purchaser shall be deemed to
have elected to pay cash) either (i) pay to the Funds by wire transfer in
immediately available funds to one or more bank accounts designated by the Funds
an aggregate amount of cash or (ii) issue shares of Purchaser Common Stock in
the manner and number calculated as provided in paragraph (ii) below (the
"Preliminary Earn-Out Payment") equal to the Preliminary Earn-Out Payment Amount
(as defined below).

                  (ii) The number of shares of Purchaser Common Stock to be
issued to the Funds in payment of the Preliminary Earn-Out Payment calculated
pursuant to Section 2.1(a)(i) above shall be fixed based on the twenty "Trading

                   (i) Not later than four (4) business days prior to the
Earn-Out Payment Date, the Purchaser shall deliver to the Funds a certificate
(the "Purchaser's Earn-Out Calculation Certificate") in the form set forth on
Schedule 2.1(b) setting forth and certifying the Purchaser's good faith
determination of (A) the Adjusted 1999 EBITDA (as defined below), (B) the
Adjusted Valuation Amount (as defined below), (C) the aggregate Capital
Expenditures (as defined below) incurred after the Closing (and prior to
September 30, 1998) for September Qualifying Projects (as defined below), (D)
the aggregate Capital Expenditures incurred after the Closing (and prior to
December 31, 1998) for December Qualifying Projects (as defined below), (E) the
aggregate Capital Expenditures incurred after the Closing (and prior to March
31, 1999) for March Qualifying Projects (as defined below), (F) 1997/1998 Room
Revenues (as defined below), (G) Lessee 1999 Adjusted Portfolio EBITDA, (H)
Excess Lessee Adjusted EBITDA, (I) the Earn-Out Ratio (as defined below) and (J)
the Earn-Out Payment Amount (as defined below), which certificate shall set
forth in reasonable detail the basis for each of such determinations.
Purchaser's determination of the Earn-Out Ratio as set forth in the Purchaser's
Earn-Out Calculation Certificate is referred to herein as the "Preliminary
Earn-Out Ratio" and Purchaser's determination of the Earn-Out Payment Amount as
set forth in the Purchaser's Earn-Out Calculation Certificate is referred to
herein as the "Preliminary Earn-Out Payment Amount." The amounts set forth in
the Purchaser's Earn-Out Calculation Certificate shall be derived from the
Purchaser's and Lessee's audited financial statements. The Funds shall have the
right to review and copy all of the computations and underlying books and
records of the Purchaser and its Subsidiaries and the Lessee that are relevant
to the determination of any amounts set forth in the Purchaser's Earn-Out
Calculation Certificate, including, without limitation, all underlying books and
records (including auditors work papers) relating to the preparation of the
Purchaser's and Lessee's audited financial statements to the extent they relate

therewith.

                  (ii) The Funds shall notify the Purchaser in writing ("Funds'
Dispute Notice") within forty-five (45) days after receiving the Purchaser's
Earn-Out Calculation Certificate if the Funds disagree with the Purchaser's
determination of the Earn-Out Payment Amount, which notice shall set forth in
reasonable detail each item which the Funds' dispute and the basis for their
disagreement. If no Funds' Dispute Notice is received by the Purchaser within
such forty-five (45) day period, the Purchaser's determination of the Earn-Out
Payment Amount shall be final and binding on the parties and shall be the final
Earn-Out Payment Amount.

                  (iii) The Funds and Purchaser shall negotiate in good faith to
resolve any disagreement with respect to the final Earn-Out Payment Amount. If
the Funds and the Purchaser are unable to agree with respect to the final
Earn-Out Payment Amount within thirty (30) days of the receipt by the Purchaser
of the Funds' Dispute Notice, the Funds and the Purchaser shall select a
mutually acceptable "big six" accounting firm other than the accounting firm
then engaged by either party (the "Independent Accounting Firm"), and submit
their dispute to the Independent Accounting Firm. The Independent Accounting
Firm will be requested to review only the disputed items identified and not
previously resolved by the Funds and the Purchaser. The Independent Accounting
Firm shall resolve such dispute after reviewing written submissions of the Funds
and the Purchaser supporting their respective determinations of the items in
dispute and stating each of their calculations of the final Earn-Out Payment
Amount. The Independent Accounting Firm shall make an independent determination
of all disputed items and then calculate the final Earn-Out Payment Amount based
upon such independent determination and the Funds' and Purchaser's determination
of all amounts not in dispute. In its determination, the Independent Accounting
Firm shall be entitled to rely on presentations prepared by the Funds and the
Purchaser. The decision of the Independent Accounting Firm shall be conclusive
between, and final and binding on, the parties hereto. The fees and expenses of
the Independent Accounting Firm will be paid by the party (either the Funds or
the Purchaser) whose calculation of the Earn-Out Payment Amount deviates the
furthest from the final Earn-Out Payment Amount as calculated by the Independent
Accounting Firm.

                  (iv) Upon the final determination of the Earn-Out Payment
Amount in accordance herewith, the Purchaser shall pay to the Funds the amount
(if any) by which the final Earn-Out Payment Amount exceeds the Preliminary
Earn-Out Payment and the Funds shall pay to the Purchaser the amount (if any) by
which the Preliminary Earn-Out Payment exceeds the final Earn-Out Payment
together, in either case with interest thereon from the date of any Dispute
Notice at a rate of interest equal to the "Prime Rate" established by Wells
Fargo Bank, N.A. on the date of payment. Such payment shall be made within five
(5) business days after all disputes, if any, have been resolved as set forth
above. Such payment shall be by wire transfer of immediately available funds to
a bank account specified by the recipient not less than two (2) business days
prior to such payment date. In the event that the final Earn-Out Payment Amount
exceeds the Preliminary Earn-Out Payment by more than $250,000 then the
Purchaser at its election may rather than paying cash as provided above issue
such number of shares of Purchaser Common Stock as is calculated in accordance
with Section 2.1(a)(ii) above.

EBITDA shall all be adjusted to reflect the pro rata interest in such Portfolio
Hotels as set forth on Schedule 2.1(c).

            (d) Allocation of Earn-Out Payment Amount. The Earn-Out Payment
Amount consisting of cash shall be paid and the Earn-Out Payment Amount
consisting of Purchaser Common Stock shall be issued to each of the Funds pro
rata in accordance with their respective percentage ownership of the Company
Common Stock as set forth on Schedule 1.3(c).

reasonably be expected to result in a material liability.

                      (iii) The Company is not required to contribute to, and
has not been required within the preceding six years to contribute to, any
"multiemployer plan" (within the meaning of section 3(37) of ERISA).

                      (iv) Each Company Plan which is intended to be qualified
within the meaning of Section 401(a) of the Code has received a favorable
determination letter from the Internal Revenue Service ("IRS") as to its
qualification, and to the best knowledge of the Company, nothing has occurred
that would reasonably be expected to result in the loss of such status.

                      (v) Schedule 3.1(p)(v) sets forth each Company Plan (other
than a multiemployer plan) that is subject to Title IV of ERISA (a "Title IV
Plan"). Except as set forth on Schedule 3.1(p)(v), no accumulated funding
deficiency or unpaid required installments within the meaning of section 412 of
the Code exists, nor has there been issued a waiver or variance of the minimum
funding standards imposed by the Code with respect to any Title IV Plan, nor has
any lien been created under section 302(f) of ERISA or security been required

the Company is a party, is bound or is otherwise liable, by its terms or in
effect would reasonably be expected to require any payment or transfer of money,
property or other consideration on account of or in connection with the sale,
lease, exchange or transfer of either any shares of stock or any of the assets
of the Company (whether or not any such payment would constitute a "parachute
payment" or "excess parachute payment" within the meaning of Section 280G of the
Code).

                      (vii) Schedule 3.1(p)(vii) sets forth a list of all
collective bargaining agreements to which the Company, its Subsidiaries or
Investment Entities is a party as of the date hereof and any pending grievances
thereunder. As of the date hereof, no demand for recognition made by any labor
organization is pending with respect to any employees of the Company or its
Subsidiaries. To the knowledge of the Company, the Company has not at any time
during the last two years (a) had, nor is there now threatened, a material
strike, picketing, work stoppage, work slowdown, lockout or other labor trouble
or dispute or grievance under any collective bargaining agreement or (b) engaged
in any unfair labor practice or discriminated on the basis of age or other
discrimination prohibited by applicable law in their employment conditions or
practices. As of the date hereof, there are no representation petitions, unfair
labor practice or age discrimination charges or complaints, or other charges or
complaints alleging illegal discriminatory practices by the Company, pending or
to the knowledge of the Company threatened before the National Labor Relations
Board or any other governmental body, which would be reasonably likely to result
in a material liability. The Company has not incurred any liability or
obligation under the Worker Adjustment and Retraining Notification Act or
similar state laws, which remains unpaid or unsatisfied.

expected to subject the Company or any of the Company Plans to any liability
under ERISA, the Code or any other applicable laws (excluding liabilities with
respect to the payment of contributions and premiums in the ordinary course),
except where such liability would not reasonably be expected to have a Company
Material Adverse Effect.

                      (x) As of the date hereof, the Company has not received
notice of any pending investigations by any governmental agency with respect to
any of the Company Plans that would reasonably be expected to subject the

3.1(t) or in the Report of Marshall and Stevens previously provided to
Purchaser, the Improvements are in a good state of condition, normal wear and
tear excepted, except where the failure to be in such condition would not,
individually or in the aggregate, reasonably be expected to have a Company

list of all material policies of insurance (other than Title Insurance

Schedule 3.1(v) and transactions among any of the Company and its Subsidiaries
and Investment Entities, there are no material contracts, agreements or
transactions between the Company, any of its Subsidiaries or its Investment
Entities, on the one hand, and the Funds or any Affiliate of the Funds, on the
other.

            (w) Investment Intention. Each Fund is acquiring its portion of the
Purchaser Common Stock Consideration and the Purchaser Convertible Preferred
Stock Consideration solely for its own account for the purpose of investment and
not with a view to or for sale in connection with any distribution thereof.

            (x) Ability to Bear Risk. The financial situation of each Fund is
such that it can afford to bear the economic risk of holding the unregistered
shares of Purchaser Common Stock and Purchaser Convertible Preferred Stock for
an indefinite period and such Fund can afford to suffer the complete loss of its
investment in the Purchaser Common Stock Consideration and the Purchaser
Convertible Preferred Stock Consideration.

            (y) Access to Information; Evaluation of Risks. (i) Each Fund has
had access to and/or has received and carefully reviewed information (including,
without limitation, financial information) regarding the Purchaser and the
shares of Purchaser Common Stock and Purchaser Convertible Preferred Stock and
has been granted the opportunity to ask questions of, and receive answers and
request information from, representatives of the Purchaser concerning the terms
and conditions of the acquisition of the Purchaser Common Stock Consideration
and the Purchaser Convertible Preferred Stock Consideration and to obtain any
additional information which it deems necessary in connection with its decision
to acquire the Purchaser Common Stock Consideration and the Purchaser
Convertible Preferred Stock Consideration and (ii) its knowledge and experience
in financial and business matters is such that it is capable of evaluating the
merits and risks of the investment in the Purchaser Common Stock Consideration
and Purchaser Convertible Preferred Stock Consideration.

            (z) Shares Not Registered. Each Fund understands and acknowledges
that the shares of Purchaser Common Stock Consideration and the Purchaser
Convertible Preferred Stock Consideration have not been registered under the
Securities Act or any other applicable securities law, and that unless so
registered may not be offered, sold or otherwise transferred except in
compliance with the registration requirements of the Securities Act or any other
applicable securities law, pursuant to an exemption therefrom or in a
transaction not subject thereto and in each case in compliance with the
conditions for transfer set forth in Section 4.13 below.

            (aa) Status of Fund. Each Fund is an "accredited investor" as
defined under the Securities Act.

            (ab) Brokers. No broker, finder or investment banker is entitled to
any brokerage, finder's or other fee or commission in connection with the
transactions contemplated by this Agreement based upon arrangements made by or
on behalf of the Company or the Funds.

            SECTION 3.2 Representations and Warranties of the Purchaser. The
Purchaser hereby represents and warrants to the Funds and the Company as
follows:

            (a) Corporate Organization. The Purchaser is a corporation duly
organized, validly existing and in good standing under the laws of the state of
its incorporation and has the requisite corporate power and authority for such
entity to own, lease and operate its properties and to carry on its business as
it is now being conducted.

            Each Subsidiary of the Purchaser is a Person duly organized, validly
existing and in good standing under the laws of the jurisdiction of its
formation and has the requisite corporate or partnership power and authority to
own, lease and operate its Properties and assets and to carry on its business as
it is now being conducted, except where the failure to be duly organized and in
good standing or to have such power and authority would not, individually or in
the aggregate, reasonably be expected to have a Purchaser Material Adverse
Effect. The Purchaser and each of its Subsidiaries is duly qualified or licensed
as a foreign corporation or partnership to do business, and is in good standing,
in each jurisdiction where the character of the properties and assets owned,
leased or operated by it or the nature of its activities makes such
qualification or licensing necessary, except for such failures to be so duly
qualified or licensed and in good stand which would not, individually or in the
aggregate, reasonably be expected to have a Purchaser Material Adverse Effect.

            (b) Capitalization. (i) The authorized capital stock of the
Purchaser consists of 50,000,000 shares of Purchaser Common Stock, $.01 par
value and 10,000,000 shares of Preferred Stock, $0.01 par value per share
("Purchaser Preferred Stock"). As of July 29, 1997, (i)(A) 20,386,635 shares of
Purchaser Common Stock were issued and outstanding, all of which were validly
issued, fully paid and nonassessable and were issued free of preemptive rights
and (B) an aggregate of 2,319,811 shares of Purchaser Common Stock were reserved
for issuance and issuable upon or otherwise deliverable in connection with the
Purchaser's dividend reinvestment and stock purchase plan or the exercise of
outstanding options or other rights to acquire shares of Purchaser Common Stock
(other than pursuant to the conversion of or exchange for operating partnership
units of Sunstone Hotel Investors, L.P.). As of the date hereof, no shares of
Purchaser Preferred Stock are issued and outstanding. As of July 29, 1997,
2,562,560 shares of the Purchaser Common Stock were reserved for issuance and/or
issuable upon or otherwise deliverable in connection with the conversion of or
exchange for operating partnership units of Sunstone Hotel Investors, L.P.

            (c) Authority Relative to Agreements. The Purchaser has all
necessary power and authority for such entity to execute and deliver this
Agreement and the Registration Rights Agreement, to perform its obligations
hereunder and thereunder and to consummate the transactions contemplated hereby
and thereby. The execution, delivery and performance of this

                                                                              34

Agreement by the Purchaser, and the consummation by the Purchaser of the
transactions contemplated hereby, have been duly authorized by the Board of
Directors of the Purchaser and no other corporate or other proceedings on the
part of the Purchaser are necessary to authorize this Agreement and the
consummation by the Purchaser of such transactions (including without
limitation, the amendment to the Certificate of Incorporation of the Purchaser
by the Certificate of Designation). The execution, delivery and performance of
the Registration Rights Agreement by the Purchaser and the consummation by the
Purchaser of the transactions contemplated thereby have been duly authorized by
all necessary corporate action by the Purchaser. This Agreement has been duly
executed and delivered by the Purchaser and, assuming due authorization,
execution and delivery by the other parties hereto, constitutes a legal, valid
and binding obligation of the Purchaser, enforceable against the Purchaser in
accordance with its terms except as enforceability may be limited by bankruptcy,
insolvency, reorganization, moratorium and other similar laws relating to or
affecting creditors' rights generally, by general equitable principles
(regardless of whether such enforceability is considered in a proceeding in
equity or at law) or by an implied covenant of good faith and fair dealing. On
the Closing Date, the Registration Rights Agreement will be validly executed and
delivered by the Purchaser and, assuming the due authorization, execution and
delivery hereof by the Fund constitute a legal, valid and binding obligation of
the Purchaser, enforceable against the Purchaser in accordance with its terms,
except as enforceability may be limited by bankruptcy, insolvency,
reorganization, moratorium and other similar laws relating to or affecting
creditors' rights generally, by general equitable principles (regardless of
whether such enforceability is considered in a proceeding in equity or at law)
or by an implied covenant of good faith and fair dealing.

            (d) No Conflict; Required Filings and Consents. (i) The execution,
delivery and performance of this Agreement by the Purchaser do not and will not:
(A) conflict with or violate the Articles of Incorporation or By-Laws of the
Purchaser, (B) assuming that all consents, approvals and authorizations
contemplated by subsection (ii) below have been obtained and all filings
described in such subsection have been made, conflict with or violate any
Governmental Regulation applicable to the Purchaser or any of its Subsidiaries
or by which any of them or their respective properties are bound or (C) assuming
that all consents, approvals and authorizations contemplated by subsection (ii)
below have had been obtained and all filings described in such clause have been
made, result in any breach or violation of or constitute a default, or give rise
to any right of termination, amendment, acceleration or cancellation of, or
result in the creation of a Lien or encumbrance on any of the property or assets
of the Purchaser or any of its Subsidiaries pursuant to, any note, bond,
mortgage, indenture, contract, agreement, lease, license, permit, franchise or
other instrument or obligation to which the Purchaser or any of its Subsidiaries
is a party or by which the Purchaser or any of its Subsidiaries or any of their
respective properties are bound.

                      (ii) The execution, delivery and performance of this
Agreement by the Purchaser and the consummation of the transactions contemplated
hereby by the Purchaser do not and will not require any consent, approval,
authorization or permit of, action by, filing with or notification to, any
Governmental Entity, except for: (A) applicable filings pursuant to the HSR Act
and the expiration or termination of all applicable waiting periods thereunder,

Property transfer gains tax or Real Property transfer tax, (D) the filing with

the Securities Exchange Act of 1934, as amended (the "Exchange Act") as may be
required in connection therewith, and (E) such other consents, approvals,
authorizations, permits, actions, filings or notifications the failure of which
to make or obtain would not, individually or in the aggregate, reasonably be
expected to have a Purchaser Material Adverse Effect or arise in connection with
the matters referred to in Section 1.5.

            (e) SEC Filings; Financial Statements. (i) The Purchaser has filed
all forms, reports, statements and other documents required to be filed with the
SEC since January 1, 1996 (collectively, the "SEC Reports"). The SEC Reports
(including the Registration Statement on Form S-1, Registration No. 33-84346),
including all the SEC Reports filed after the date of this Agreement and prior
to the Closing Date, were or will be in compliance in all material respects with
the applicable requirements of the Securities Act or the Exchange Act, as
applicable, each as in effect on the date so filed. None of the SEC Reports

            SECTION 4.8 Public Announcements. The Purchaser, on the one hand,
and the Company and the Fund, on the other hand, shall consult with each other
before issuing any press release or otherwise making any public statements with
respect to the Stock Purchase, shall provide each other the opportunity to
review and comment upon, any such press release or public statement, and shall
not issue any such press release or make any such public statement prior to such
consultation, except as may be required by law or any listing agreement with any
securities exchange on which its securities are listed. The parties agree that
the initial press release to be issued with respect to the Stock Purchase shall
be in the form heretofore agreed to by the parties.

            SECTION 4.9 Maintenance of REIT Qualification. If at any time either
the Purchaser or the Funds believes that the consummation by the Purchaser of
the transactions contemplated by this Agreement, after giving effect to the
additional actions contemplated by Schedule 1.5 hereto, would result in the
Purchaser losing its REIT Qualification, such party shall promptly advise the
others of such belief and the reasons therefore and all parties will negotiate
in good faith and use their respective best efforts to agree to such
modifications to the transactions contemplated by this Agreement and Schedule
1.5 as may be necessary to allow the consummation of the transactions
contemplated hereby without the loss of the Purchaser's REIT Qualification and
in a manner that does not diminish in any material respect the benefits of the
transactions contemplated hereby to the Funds and the Purchaser.

            SECTION 4.10 Transfer Restrictions. (a) Each Fund covenants and
agrees that all shares of Purchaser Common Stock and the Purchaser Convertible
Preferred Stock constituting the Purchaser Common Stock Consideration and the
Purchaser Convertible Preferred Stock Consideration or received upon conversion
of the Purchaser Convertible Preferred Stock and issued to such Fund (the
"Shares") will not be transferred or otherwise disposed of except in a
transaction registered or exempt from registration under the Securities Act.
Each Fund agrees that, without the consent of the Purchaser, such Fund will not,
directly or indirectly, offer, transfer, sell, pledge, hypothecate or otherwise
dispose of any of the Shares, except for (i) sales in compliance with Rule 144
under the Securities Act, (ii) a public offering of Shares in accordance with
the registration rights set forth in the Registration Rights Agreement or (iii)
a sale, pledge, hypothecation or other disposition in connection with which such
Fund shall have delivered to the Purchaser a written opinion of legal counsel to
such Fund, reasonably satisfactory in form and substance to the Purchaser, to
the effect that the transaction may be effected without registration under the
Securities Act.

            (b) Each Fund covenants and agrees that, notwithstanding anything
herein to the contrary, such Fund will not, directly or indirectly, transfer,
sell or otherwise dispose of any Shares for a period of twelve (12) months after
the Closing Date (the "Initial Lock-Up Period"). Following the Initial Lock-Up
Period, the Funds shall be permitted to sell, transfer or otherwise dispose of
the following percentages of all Shares owned by the Funds on the day after the
Closing Date (which number of Shares shall be increased or decreased as
appropriate in the event that the number of issued and outstanding shares of
Purchaser Common Stock shall have been changed into a different number of shares
or a different class by reason of any stock dividend, subdivision,
reclassification, recapitalization, split, combination, exchange of shares or
otherwise):

(i) up to 25% of the Shares may be sold, transferred or otherwise disposed of
during the period ending on the three month anniversary of the last day of the
Initial Lock-Up Period; (ii) up to 50% of the shares may be sold, transferred or
otherwise disposed of during the period ending on the six month anniversary of
the last day of the Initial Lock-Up Period; (iii) up to 75% of the shares may be
sold, transferred or otherwise disposed of during the period ending on the nine
month anniversary of the last day of Initial Lock-Up Period and (iv) on the day
after the one year anniversary of the last day of the Initial Lock-Up Period all
restrictions in this clause (b) will terminate; provided that following the
Initial Lock-Up Period, the Funds may, in their sole discretion, distribute
solely to their respective limited and general partners all or any portion of
the Shares in a registered offering utilizing the registration rights provided
for in the Registration Rights Agreement. For purposes of determining the number
of Shares sold, transferred or otherwise disposed of for purposes of this clause
(b), the Purchaser Common Stock and Purchaser Convertible Preferred Stock shall
be aggregated and considered together, with the Purchase Convertible Preferred
Stock being treated on an as converted basis.

            SECTION 4.11      Board Representation.

            (a) (i) The Purchaser shall increase the number of authorized
      directors from 8 to 9 and cause one person designated by the Funds to be
      elected to fill the vacancy created on the Board of Directors of the
      Purchaser, effective upon the Closing Date. Thereafter, in the event that
      the Purchaser shall increase the number of members of its Board of
      Directors, the Funds shall be entitled to have a number of representatives
      on the Board of Directors of the Purchaser so that the Funds
      representation on the Board of Directors of the Purchaser shall equal a
      number of directors equal to the product of the total number of directors
      on such Board multiplied by the percentage of the outstanding Purchaser
      Common Stock that is beneficially owned by the Funds (other than shares
      purchased by the Funds from any person other than the Purchaser) on a
      fully diluted basis (including the shares of Purchaser Common Stock
      issuable upon conversion of the Purchaser Convertible Preferred Stock)
      provided, however, that such calculation shall be rounded to the nearest
      whole number of directors; provided, further, that, unless otherwise
      provided in Section 4.1(a)(ii), irrespective of the above calculation, the
      Funds shall have at least one designee on the Board of Directors of the
      Purchaser. In the event that the Funds are entitled to designate more than
      one person to serve on the Purchaser's Board of Directors, the Funds'
      designees shall be allocated among the Purchaser's classes of directors as
      equally as possible.

                  (ii) If the number of directors designated by the Funds is
      increased to greater than one pursuant to Section 4.11(a)(i), then the
      Purchaser agrees that as long as the Funds continue to beneficially own in
      the aggregate a number of shares of the Purchaser Common Stock equal to at
      least 50% of the outstanding Purchaser Common Stock beneficially owned by
      the Funds immediately following the Closing, which calculation shall be
      made as appropriate to take into account any conversions,
      reclassifications, reorganizations, in-kind dividends, splits, reverse
      splits and similar events that may occur with the Purchaser Common Stock,
      at all meetings of the stockholders of

                                                                              46

      the Purchaser at which members of the Purchaser's Board of Directors are
      elected, the Purchaser shall nominate for election as a director as part
      of the management slate, a number of persons designated by the Funds such
      that if such persons were elected as directors the number of directors of
      the Purchaser designated by the Funds pursuant to this Section would equal
      the number of directors as determined pursuant to Section 4.11(a)(i). The
      Purchaser also agrees that as long as the Funds continue to beneficially
      own in the aggregate a number of shares of the Purchaser Common Stock
      equal to at least 33 1/3% but less than 50% of the Purchaser Common Stock
      beneficially owned by the Funds immediately following the Closing, which
      calculation shall be made as appropriate to take into account any
      conversions, reclassifications, reorganizations, in-kind dividends,
      splits, reverse splits and similar events that may occur with the
      Purchaser Common Stock, at all meetings of the stockholders of the
      Purchaser at which members of the Purchaser's Board of Directors are
      elected, the Purchaser shall nominate for election as a director as part
      of the management slate, one person designated by the Funds unless a
      person designated by the Funds pursuant to this Section is serving as a
      director of the Purchaser and such person's term will not expire in
      connection with such shareholder meeting. The Purchaser agrees to provide
      the same type of support for the election of the designees of the Funds as
      directors of the Purchaser, its affiliates and its management provides to
      other persons standing for election as directors of the parent as part of
      the management slate. In the event that any designee of Purchaser for
      election to the Purchaser's Board of Directors pursuant to the foregoing
      provisions shall cease to serve as a director for any reason (other than
      the failure of the stockholders of Purchaser to elect such person as a
      director), the vacancy resulting therefrom shall be filled by a designee
      of the Funds.

                  (iii) As long as the Funds have the right to designate at
      least one nominee to the Board of Directors of the Company, unless
      otherwise agreed by the Funds, each Committee of the Purchaser's Board of
      Directors will contain at least one member designated by the Funds.

                  (iv) The Purchaser shall furnish to the Funds' designee or
      designees, as the case may be, on the Purchaser's Board of Directors all
      information that is provided to the other members of the Board of
      Directors of the Purchaser.

                  (v) The Purchaser and the Funds agree that any breach of this
      Section 4.11 would cause irreparable injury to the Funds and that money
      damages will be an inadequate remedy for any breach or threatened breach
      of the agreements described in this Section 4.11. The Purchaser agrees
      that in the event of a breach or a threatened breach of the agreements
      described in this Section 4.11, the Funds shall, in addition to other
      rights and remedies existing in their favor, be entitled to specific
      performance and/or injunctive relief in order to enforce, or prevent any
      violations of, the provisions of this Section 4.11 (without the posting of
      a bond or other security).

            SECTION 4.12 Amendment of Articles of Incorporation. On or prior to
the Closing Date, the Purchaser shall amend its Certificate of Incorporation by
filing the Certificate

of Designation with the Secretary of the State of Delaware. As long as any
shares of Purchaser Convertible Preferred Stock remain outstanding, Purchaser
will reserve and have available for issuance to the holders of the Purchaser
Convertible Preferred Stock upon conversion thereof a number of authorized but
unissued shares of the Purchaser Common stock equal to the number of shares of
Purchaser Common Stock issuable upon conversion of the Purchaser Convertible
Preferred Stock.

            SECTION 4.13 Non-Solicitation. If the transactions contemplated
hereby have been abandoned pursuant to Section 6.1 or if this Agreement shall
have been terminated for any reason, the Purchaser hereby agrees that from the
date hereof until the date of such termination or abandonment and for a period
of twenty-four (24) months thereafter, Purchaser shall not, on its own behalf or
an behalf of any person, firm or company, directly or indirectly, solicit or
offer employment to any person who is or has been employed by the Company or its
Subsidiaries or its Investment Entities at any time during the twelve (12)
months immediately preceding such solicitation.

            SECTION 4.14 No Negotiation. Until such time, if any, as this
Agreement is terminated pursuant to Section 6.1, the Funds will not, and will
cause the Company and its Subsidiaries and their respective employees and agents
not to, directly or indirectly, solicit, initiate, or encourage any inquiries or
proposals from, discuss or negotiate with, provide any non-public information
to, or consider the merits of any unsolicited inquiries or proposals from, any
Person (other than the Purchaser) relating to any transaction involving the sale
of all or substantially all of the business or assets of the Company or any
Subsidiary of the Company, or any of the capital stock of the Company or any
Subsidiary of the Company, or any merger, consolidation, business combination,
or similar transaction involving the Company or any Subsidiary of the Company.

            SECTION 4.15 Organization and Qualification of Subsidiaries. The
Company shall use its reasonable best efforts to provide the Purchaser, as soon
as reasonably practicable following the date hereof, the records identified on
Schedule 3.1(a). In addition, to the extent any Subsidiary is not duly
organized, validly existing and in good standing under the laws of the
jurisdiction of its formation and, with respect to each Subsidiary that owns a
Hotel Property or material asset, qualified to do business in the state where
such Hotel Property or other material asset is located, the Company shall, at
the Funds' sole cost and expense, take all action necessary to make such
Subsidiary duly organized, validly existing and in good standing or qualified to
do business, as applicable, in such jurisdiction prior to the Closing.

            SECTION 4.16 Licenses and Permits. As soon as practicable, and in
any event no later than thirty (30) days after the date hereof, the Company
shall provide Purchaser with a list and copies of all Licenses and Permits
possessed by the Company and its Subsidiaries.

            SECTION 4.17      Additional Information.

            Within 30 days of the date hereof, the Company shall provide
Purchaser with a list and copies of all agreements pursuant to which the Company
or its Subsidiaries is or may be liable for a payment of in excess of $5,000 in
any given year.

            SECTION 4.18 New York Stock Exchange Listing. The Purchaser shall,
if permitted by the rules of the New York Stock Exchange (the "NYSE") or such
other national securities exchange as the Purchaser Common Stock may be listed,
list and keep listed on the NYSE or such other national securities exchange as
the Purchaser Common Stock may be listed, all shares of the Purchaser Common
Stock Consideration which have been registered under the Securities Act for so
long as the Purchaser Common Stock remains so listed.

            SECTION 4.19 Share Trust. The Purchaser shall not repurchase, redeem
or otherwise acquire any of the Purchaser Common Stock if such action would
cause any of the Purchaser Common Stock Consideration or the Purchaser Preferred
Stock Consideration, or any shares of the Purchaser Common Stock issued to the
Funds upon the conversion thereof, to be transferred pursuant to the Purchaser's
Amended Articles of Incorporation to the Share Trust (as such term is defined in
Section 2(a) of such Articles of Incorporation); provided that for purposes of
determining whether such a repurchase, redemption or acquisition of Purchaser
Common Stock would cause such a transfer to the Share Trust, it shall be assumed
that: (i) each constituent partner of the Funds owns (independent of such
partner's ownership in the Fund) no more Purchaser Common Stock than such
partner owned on the Closing Date, and (ii) each such constituent partner's
percentage ownership interest in the Funds is the lesser of (A) such partner's
actual ownership percentage at the time of the repurchase, redemption or
acquisition, or (B) such partner's ownership percentage as delivered to the
Purchaser prior to the date hereof. If there is a reasonable question on the
part of the Funds as to whether an intended repurchase, redemption or other
acquisition by the Purchaser of the Purchaser Common Stock will cause such a
transfer to the Share Trust, upon receipt by the Funds and approval by the
Funds' counsel of an opinion to the Purchaser from counsel to the Purchaser in
form and substance reasonably satisfactory to the Funds to the effect that the
intended acquisition will not cause such a transfer to the Share Trust, the
Company will be permitted to effect such repurchase, redemption or other
acquisition, provided, that the Purchaser will remain liable for any breach of
the first sentence of this Section 4.19 with respect to such transaction. The
Funds shall provide the Purchaser and its counsel such written representations
of and undertakings on the part of the Funds addressing such matters as shall be
reasonably required by such counsel in connection with the preparation of such
opinion.

            SECTION 4.20 Earnings and Profits Distribution. (a) (i) Subject to
the terms and conditions set forth in this Section 4.20, the Company will seek
to obtain all necessary financing for the Distribution from one or more
financial institutions (excluding the Funds or the Purchaser) on the terms and
conditions set forth in this Section 4.20 (the "Distribution Financing"), and
the Purchaser will not participate in obtaining the Distribution Financing
(other than, if requested by the Company, identifying potential sources of the
Distribution Financing).

The Distribution Financing may be secured only by assets of the Company and/or
its Subsidiaries and shall be repayable solely from such assets and/or the
earnings and profits of such assets; provided that the Distribution Financing
may include a general recourse obligation of the Company prior to the
contribution of its assets to a limited liability company or grantor trust as
contemplated by Schedule 1.5 and, after such contribution, to such limited
liability company or grantor trust; provided further that the lenders shall not
have any general recourse to the Purchaser or its assets other than the Company
and/or its Subsidiaries and the Purchaser shall not be required to guarantee or
otherwise provide assurances to the lenders or be a party to the agreements with
respect to the Distribution Financing but shall have the right to approve the
Distribution Financing, which approval shall not be unreasonably withheld (with
the ability of the Purchaser to withhold its consent being subject to its using
its reasonable best efforts to cause the satisfaction of the conditions in
Article V hereof and such approval not to be withheld on the basis of the
security granted for such Financing or its maturity as long as such terms comply
with the provisions hereof, and the Purchaser will also not be permitted to
withhold its consent if the Distribution Financing can be repaid at the option
of the borrower without penalty). The Company will use its reasonable commercial
efforts to have the Distribution Financing secured by as few Properties of the
Company and its Subsidiaries as the Company in good faith believes is practical
in order to obtain such financing, provided that the Company will be entitled to
have such financing secured by as many Properties of the Company as it deems
necessary in order to obtain such financing and shall not secure the financing
with any assets other than Properties or the proceeds thereof. The maturity date
of the Distribution Financing will be at least two years after the Closing Date.
Neither the Purchaser nor the Funds shall be responsible for the costs and
expenses of the Company seeking to arrange, or effecting, the Distribution
Financing.

      (ii) Notwithstanding the foregoing, the Funds may, but shall not be
obligated to, fund the Distribution by accepting a promissory note (the
"Distribution Note") issued by the Company as a dividend to the Funds. The
Distribution Note, if issued, and related security shall be on the same terms
and conditions as the Distribution Financing described in Section 4.20(a)(i)
except that the Distribution Note shall mature in two years, subject to optional
prepayment by the borrower without penalty and, the borrower will have the right
within 60 days of issuance to repackage the collateral for such loan with first
mortgages on Hotel Properties having a loan to value ratio based on recent MAI
Appraisals on commercially reasonable terms mutually acceptable to the Purchaser
and the Funds.

            (b) In the event that the Company determines in good faith that it
is unable to obtain the Distribution Financing described in Section 4.20(a)(i)
from parties other than the Funds and the Funds determine in their sole
discretion not to finance the Distribution as permitted by Section 4.20(a)(ii),
the Company, the Funds and the Purchaser will negotiate in good faith and use
their respective reasonable best efforts to agree upon an alternative structure
to fund the Distribution in a manner that, unless agreed otherwise by the
parties hereto, does not diminish in any material respect the benefits of the
transactions contemplated hereby to the Funds and the Purchaser does not cause
the Purchaser to lose its REIT Qualification.

            (c) Notwithstanding the foregoing, (A) the Funds shall not be
required to incur or assume any liability or obligation of any nature
(including, without limitation, making any amendment or modification to any
existing agreement, arrangement or understanding to any Governmental Entity or
other third party), and (B) neither the Company, the Purchaser nor any of their
respective Subsidiaries shall be required to incur or assume any liability or
obligation of any nature (including, without limitation, making any amendment or
modification to any existing agreement, arrangement or understanding) with
respect to the Distribution Financing until the day immediately preceding the
Closing Date and receipt of satisfactory evidence that the conditions to the
Closing in Article V will be satisfied on the date of Closing, but thereafter
the consummation of the Distribution Financing will not be contingent on the
Closing.

            SECTION 4.21 GMX. The Company shall use its reasonable best efforts
to ensure that on or before the Closing Date, the Company owns 100% of the
outstanding shares of the common stock of GMX, Inc.

            SECTION 4.22 Non-Core Assets. The Company shall use commercially
reasonably efforts to sell the Non-Core Assets set forth on Schedule 4.22;
provided, however, that the Company will not enter into any contract or other
obligation to sell any of the Non-Core Assets without the prior consent of the
Purchaser, which consent shall not be unreasonably withheld.

                           CONDITIONS TO THE CLOSING

            SECTION 5.1 Conditions to Obligation of Each Party to Effect the
Merger. The respective obligations of each party to effect the Closing shall be
subject to the satisfaction at or prior to the Closing Date of the following
conditions precedent:

            (a) Government Approvals. All consents, approvals, authorizations or
permits of, actions by, or filings with or notifications to, and all expirations
of waiting periods imposed by, any Governmental Entity listed on Schedule 5.1(a)
shall have been filed, occurred or been obtained and shall be in full force and
effect.

            (b) No Injunctions or Restraints; Illegality. No temporary
restraining order, preliminary or permanent injunction or other order issued by
any court of competent jurisdiction or other legal restraint or prohibition
preventing the consummation of the Stock Purchase shall be in effect, no action
or proceeding shall have been commenced by any Governmental Entity seeking any
injunction, restraining order or other order which seeks to prohibit
consummation of the Stock Purchase, and no action or proceeding shall have been
commenced by any Governmental Entity seeking material damages in connection with
the Stock Purchase shall be pending; provided, however, that the parties
invoking this condition shall use reasonable efforts to have any such action,
proceeding, order or injunction vacated. There shall not be any action

<PAGE>   57
                                                                              51

taken, or any statute, rule, regulation or order enacted, entered, enforced or
deemed applicable to the Stock Purchase, which makes the consummation of the
Stock Purchase illegal.

            (c) Maintenance of REIT Qualification. Neither the Purchaser nor the
Funds shall have determined in good faith based upon the written opinion of
outside counsel that the consummation by the Purchaser of the transactions
contemplated by this Agreement, after giving effect to the additional actions
contemplated by Schedule 1.5 hereto and despite efforts by the Purchaser and the
Funds to restructure the transactions contemplated hereby and by Schedule 1.5 in
order to preserve the Purchaser's REIT Qualification pursuant to Section 4.9,
would result in the Purchaser losing its REIT Qualification.

            (d) Earnings and Profits Certification. The Company and the
Purchaser shall have obtained the certification of the earnings and profits
calculation from KPMG as provided in Section 1.4 in a form reasonably acceptable
to the Purchaser and the Funds, and such certification shall have been revised
by KPMG to include the earnings and profits actually generated between the date
of the original certification pursuant to Section 1.4 and the most recent date
through which the earnings and profits are ascertainable as well as a reasonable
estimate of any earnings and profits from such most recent date through the
Closing Date, and Ernst and Young, LLP shall have reviewed and approved in the
exercise of its reasonable judgment the certification and workpapers of KPMG.

            (e) Confirmation of Exempted Holder Status for Funds. No later than
two weeks following receipt by the Funds of a draft legal opinion from counsel
to the Purchaser to the effect that the proposed ownership by the Funds of the
shares of Purchaser Common Stock Consideration or Purchaser Convertible
Preferred Stock Consideration will not violate the restrictions contained in
Sections 2(b)(i)(x), 2(b)(i)(y) and 2(b)(i)(z) of Article V of the Amended
Articles of Incorporation of the Purchaser, the Funds shall provide the
Purchaser and its counsel (i) such representations and undertakings regarding
the Funds and its constituent partners as are reasonably necessary to address
the assumptions contained in such legal opinion regarding the Funds status as an
Exempted Holder (as defined in the Purchaser's Amended Articles of
Incorporation) and (ii) on or prior to the Closing, the Funds shall deliver to
the Purchaser written assurance that the Funds agree that any violation or
attempted violation by any individual of the Ownership Limit (as defined in
Section 2(a) of Article V of the Purchaser's Amended Articles of Incorporation)
due to such individual's Beneficial Ownership of the Purchaser Common Stock
Consideration or Purchaser Convertible Preferred Stock Consideration (or any
shares of Common Stock issued upon conversion thereof) (as defined in Section
2(a) of the Purchaser's Amended Articles of Association) will result in transfer
of their shares to the Share Trust as defined in and pursuant to Section 2(c) of
Article V of the Amended Articles of Incorporation.

            SECTION 5.2 Conditions to Obligations of Purchaser. The obligations
of the Purchaser to effect the transactions contemplated by this Agreement are
further subject to the satisfaction of the following conditions prior to the
Closing Date unless waived by the Purchaser:

            (a) Representations and Warranties. (i) The representations and
warranties of the Funds set forth in this Agreement shall be true, correct and
complete as of the date of this Agreement and (except to the extent such
representations and warranties speak as of an earlier date) as of the Closing
Date as though made on and as of the Closing Date, except as otherwise
contemplated by this Agreement and except for such failures to be true, correct
and complete as of the Closing Date that would not individually or in the
aggregate reasonably be expected to have a Company Material Adverse Effect (it
being agreed that any matter for which the Purchaser is compensated pursuant to
clause (iv) of Section 7.1(c) shall not be deemed to have a Company Material
Adverse Effect) or arise out of or relate to the transactions referred to in
Section 1.5, and (ii) the Purchaser shall have received certificates to such
effect signed on behalf of the Funds by the general partner of the Funds,
respectively; provided, however, that receipt of such certificate shall not be
evidence that the Purchaser concurs with anything set forth in such certificate.

            (b) Performance of Obligations of the Company and the Funds. The
Company and the Funds shall have performed in all material respects all material
obligations, required to be performed by it under this Agreement at or prior to
the Closing Date, and the Purchaser shall have received certificates to such
effect signed on behalf of the Company (with respect to the Company's
obligations) and the Funds (with respect to the Funds' obligations) by the chief
financial officer of the Company and the general partners of the Funds,
respectively.

            (c) Required Consents; Governmental Approvals. (i) All Required
Consents shall have been obtained on terms and conditions that comply with the
terms of any side letter and that would not have a Company Material Adverse
Effect and shall be in full force and effect, and (ii) Purchaser shall have
received all consents, approvals, Licenses and Permits of Governmental Entities
so as to enable Sunstone Hotel Investors, L.P. to own the Properties (or the
Investment Entities to own the Properties owned by the Investment Entities on
the date hereof) and to enable Sunstone Hotel Properties, Inc. to operate the
Properties immediately following the Closing Date substantially in the same
manner as operated on the date hereof; provided that with respect to Licenses
and Permits or other governmental consents or approvals that can be obtained
only after consummation of the Stock Purchase, such consents, approvals,
Licenses or Permits shall not be a condition precedent if Purchaser shall have
not received advice from its counsel, after due inquiry of the appropriate
regulatory agency or from the appropriate regulatory agency to the effect that
there is a substantial possibility that such Licenses and Permits will not be
obtained promptly following such consummation and that failure to procure the
applicable License and Permit will result in a Company Material Adverse Effect.

            (d) No Material Adverse Change. Since the date hereof, (i) there
shall have been no material adverse change in the business, Properties, assets,
results of operations, financial condition or prospects of the Company and its
Subsidiaries taken as a whole, nor (ii) shall there have been any development
which, taken together with all other developments in the aggregate, would
reasonably be expected to result in such a material adverse change, in each case
of clause (i) and (ii) except for such developments or changes arising out of or
relating to the transactions

            SECTION 6.1 Termination. This Agreement may be terminated and the
Stock Purchase contemplated hereby may be abandoned at any time prior to the
Closing Date:

            (a)   by mutual written consent of the Purchaser and the Funds;

            (b) by the Purchaser, upon a breach of any representation, warranty,
covenant or agreement on the part of the Company or the Funds set forth in this
Agreement, or if any such representation or warranty of the Company or the Funds
shall have been or become untrue, in each case such that the conditions set
forth in Section 5.2(a) or Section 5.2(b), as the case may be, would be
incapable of being satisfied (following notice and failure to cure within 20
days of such notice);

            (c) by the Funds, upon a breach of any representation, warranty,
covenant or agreement on the part of the Purchaser set forth in this Agreement,
or if any such representation or warranty of the Purchaser shall have been or
become untrue, in each case such that the conditions set forth in Section 5.3(a)
or Section 5.3(b), as the case may be, would be incapable of being satisfied
(following notice and failure to cure within 20 days of such notice);

            (d) by either the Purchaser or the Funds, if any permanent
injunction or action by any Governmental Entity preventing the consummation of
the Stock Purchase or transactions contemplated by Section 1.5 shall have become
final and nonappealable;

            (e) by either the Purchaser or the Funds if the Stock Purchase shall
not have been consummated on or prior to December 31, 1997; or

            (f) by the Funds in the event that all of the conditions precedent
in Sections 5.1 and 5.2 are satisfied or would be satisfied but for a breach of
this Agreement by the Purchaser, the Funds are prepared to effect the
transactions required to occur on the day before the Closing and on the Closing
Date and the Purchaser is unable to effect the Closing due to the Purchaser not
having available all necessary financing, subject to the right of the Purchaser
to delay the Closing Date pursuant to the proviso in Section 1.2.

            SECTION 6.2 Effect of Termination. In the events of the termination
of this Agreement pursuant to Section 6.1, this Agreement shall forthwith become
void and there shall be no liability on the part of any party hereto except as
set forth in Section 4.3, in Section 7.1 and in the immediately succeeding
sentence; provided, however, that nothing herein shall

                                                                              56

relieve any party from liability for any willful and material breach hereof. The
Purchaser shall be liable to the Funds for all direct, actual damages (and all
expenses incurred by the Funds and the Company in connection with the
preparation, negotiation and execution of this Agreement and the taking of all
actions contemplated hereby) incurred by the Funds due to the failure of the
Closing to occur if this Agreement is terminated pursuant to Section 6.1(f).

written environmental and engineering reports prepared by Purchaser's
consultants.

6.4 and Section 6.2, the Purchaser and the Funds shall each bear their own fees
and expenses in connection with this Agreement and the transactions contemplated
hereby. Without limiting the foregoing, the Funds shall pay all fees and
expenses of Simpson Thacher & Bartlett, counsel to the Funds, incurred in
connection with the preparation, negotiation and execution of this Agreement and
the consummation of the transactions contemplated hereby.

            SECTION 6.5 Amendment. This Agreement may be amended, supplemented
or otherwise modified by the parties hereto only by written agreement executed
and delivered by duly authorized officers of the respective parties.

            SECTION 6.6 Waiver. Any party hereto may (a) extend the time for the
performance of any of the obligations or other acts of the other parties hereto,
(b) waive any inaccuracies in the representations and warranties contained
herein or in any document delivered pursuant hereto or (c) waive compliance with
any of the agreements or conditions contained herein. Any such extension or
waiver shall be valid only if set forth in an instrument in writing signed by
the party or parties to be bound thereby. The failure of any party to this
Agreement to assert any of its rights under this Agreement or otherwise shall
not constitute a waiver of such rights.


                                  ARTICLE VII

                              GENERAL PROVISIONS

notwithstanding the foregoing, (i) the representations and warranties contained

<PAGE>   63
                                                                              57

Terminating Representations") shall survive the Closing and shall not terminate
and (iii) the agreements in Sections 4.3(c) (as it applies to Section 4.3(b)
only), 4.4, 4.5, 4.10, 4.11, 4.12, 4.18 and 4.19 shall survive the Closing and
shall not terminate (collectively, the "Non-Terminating Pre-Closing
Agreements"). No party shall have any liability or obligation of any nature with
respect to any representation, warranty or pre-Closing agreement after the
termination thereof.

            (b) Indemnification by Purchaser. Subject to Section 7.1(d), (e),
(f) and (h), from and after the Closing Date, the Purchaser shall indemnify and
hold harmless the Funds, the Funds' Affiliates, each of their respective
directors, officers, employees and agents, and each of the heirs, executors,
successors and assigns of any of the foregoing from and against any and all
damages, claims, losses, expenses, costs, obligations and liabilities including
without limiting the generality of the foregoing, liabilities for all reasonable
attorneys' fees and expenses (including attorney and expert fees and expenses
incurred to enforce the terms of this Agreement in the event of a breach)
(collectively, "Losses and Expenses") suffered or incurred by any such
indemnified Person arising from, relating to or otherwise in respect of, (i) any
breach of, or inaccuracy in, any representation or warranty of the Purchaser
contained in this Agreement or in the certificate delivered pursuant to Section
5.3(a) of this Agreement and (ii) any breach of any agreement of the Purchaser
contained in this Agreement.

            (c) Indemnification by the Funds. Subject to Sections 7.1(d), (e),
(f) and (h), from and after the Closing Date, the Funds shall, jointly and
severally, indemnify and hold harmless the Purchaser, Purchaser's Affiliates,
each of their respective directors, officers, employees and agents, and each of
the heirs, executors, successors and assigns of any of the foregoing from and
against any and all Losses and Expenses suffered or incurred by any such
indemnified Person arising from, relating to or otherwise in respect of, (i) any
breach of, or inaccuracy in, any representation or warranty of the Funds
contained in this Agreement or in the certificates delivered pursuant to Section
5.2(a) of this Agreement, (ii) any breach by the Funds of Section 4.1 of this
Agreement or the related provisions of the certificate delivered pursuant to
Section 5.2(b) other than a breach of any provision of clause (a) through (m)
(which shall be subject to indemnification pursuant to clause (iii) hereof),
(iii) any breach of any agreement of the Funds contained in this Agreement
except for matters covered by clause (ii), and (iv) for the matters (and in the
manner) set forth on Schedule 7.1(c).

            (d) Limitations on Indemnification. Neither the Purchaser nor the
Funds shall have any obligation to indemnify any indemnified person pursuant to
clause (i) of Section 7.1(b) or clause (i) of Section 7.1(c) (other than with
respect to a Non-Termination Representation, which shall not be subject to this
Section 7.1(d)) unless the aggregate of all Losses and Expenses in respect of
all matters subject to such claims would, but for this section, exceed
$2,500,000, in which case the Purchaser or the Funds, respectively, shall,
subject to the immediately succeeding sentence, be liable for all amounts in
excess of such $2,500,000 threshold; provided, however, that no threshold shall
apply to breaches of representations contained in Section 3.1(c)(i) as to the
percentage ownership of capital stock of those corporate entities identified by
the footnotes on Schedule 3.1(c)(i). The maximum aggregate liability of the
Purchaser on the one hand and the Funds, collectively, on the other for all
Losses and Expenses incurred by all


                                Page 88 of 139

<PAGE>   64
                                                                              58

indemnified parties for all matters subject to clause (i) of Section 7.1(b) or
clause (i) of Section 7.1(c) (in each case other than with respect to
Non-Terminating Representations, which shall not be subject to this Section
7.1(d)), as applicable, is $5,000,000 in the aggregate for all matters and
neither the Purchaser nor the Funds shall have any obligation or liability
pursuant to such clauses in excess of such amount.

            (e) Third-Party Claims. If a claim by a third party is made against
an indemnified Person hereunder, and if such indemnified Person intends to seek
indemnity with respect thereto under this Article, such indemnified Person shall
promptly notify the indemnifying Person in writing of such claims setting forth
such claims in reasonable detail, provided that failure of such indemnified
Person to give prompt notice as provided herein shall not relieve the
indemnifying Person of any of its obligations hereunder, except to the extent
that the indemnifying Person is materially prejudiced by such failure. The
indemnifying Person shall have twenty (20) days after receipt of such notice to
undertake, through counsel of its own choosing, subject to the reasonable
approval of such indemnified Person, the settlement or defense thereof, and the
indemnified Person shall cooperate with it in connection therewith; provided,
however, that the indemnified Person may participate in such settlement or
defense through counsel chosen by such indemnified Person; provided that the
fees and expenses of such counsel shall be borne by such indemnified Person. If
the indemnifying Person shall assume the defense of a claim, it shall not settle
or compromise such claim without the prior written consent of the indemnified
Person (which consent shall not be unreasonably withheld) unless (i) the
indemnifying Person agrees in writing that the indemnified Person is entitled to
indemnification in respect of such claim pursuant to this Section 7.1, (ii) such
settlement or compromise includes as an unconditional term thereof the giving by
the claimant of a release of the indemnified Person from all liability with
respect to such claim and (iii) such settlement or compromise does not involve
the imposition of equitable remedies or the imposition of any obligations on
such indemnified Person other than financial obligations for which such
indemnified party will be indemnified hereunder. If the indemnifying Person
shall assume the defense of a claim, all fees and expenses of the indemnifying
Person's counsel and other costs of defending such claim shall be borne by the
indemnifying party; provided that the fees of any separate counsel retained by
the indemnified Person shall be borne by such indemnified Person unless there
exists a conflict between them as to their respective legal defenses (other than
one that is of a monetary nature), in which case the indemnified Person shall be
entitled to retain separate counsel, the reasonable fees and expenses of which
shall be reimbursed by the indemnifying Person. If the indemnifying Person does
not notify the indemnified Person within twenty (20) days after the receipt of
the indemnified Person's notice of a claim of indemnity hereunder that it elects
to undertake the defense thereof, the indemnified Person shall have the right to
defend the claim and shall not settle or compromise the claim without the
consent of the indemnifying party (which consent will not be unreasonably
withheld) unless the indemnifying party agrees in writing that it is not
entitled to any indemnities pursuant to this Section 7.1.

            (f) Termination of Indemnification. The obligations to indemnify and
hold harmless a Person pursuant to Section 7.1(b) or 7.1(c) shall terminate when
the applicable representation, warranty or agreement terminates pursuant to
Section 7.1(a); provided, however,


                                Page 89 of 139

<PAGE>   65
                                                                              59

that such obligation to indemnify and hold harmless shall not terminate with
respect to any item as to which the person to be indemnified shall have, after
the Closing Date but before the expiration of the applicable period, previously
made a claim by delivering a written notice (stating in reasonable detail the
basis of such claim) to the indemnifying party; provided, further, that a claim
for any item under Section 3.1(q) shall not be deemed made with respect to any
Tax until such time as the Purchaser receives written notice from a taxing
authority asserting that such Tax is due or, if earlier, such time as Purchaser,
its Subsidiary or Investment Entity has actually paid such Tax (but such claim
will be deemed made only to the extent of such payment).

            (g) Exclusive Remedy. After the Closing Date, the indemnification
provided pursuant to this Section 7.1 shall be the sole and exclusive remedy of
any party hereto for any Losses and Expenses arising out of or relating to any
breach of any representation, warranty or agreement contained in this Agreement.

            (h) Calculation of Loss and Expenses. In the event of any breach of
representation and warranty contained in Section 3.1 or Section 3.2, the amount
of Losses and Expenses arising from, relating to or otherwise in respect of such
breach shall be determined based on the entire amount of any such Losses and
Expenses, not merely the portion above any "Material Adverse Effect" or other
materiality qualifiers contained in the applicable representation and warranty.

            SECTION 7.2 Notices. All notices, requests, claims, demands and
other communications hereunder shall be in writing and shall be given (and shall
be deemed to have been duly given upon receipt) by delivery in Person, by cable,
telecopy, telegram or telex or by registered or certified mail (postage prepaid,
return receipt requested) to the respective parties at the following addresses

                ARTICLES SUPPLEMENTARY CLASSIFYING 250,000 SHARES
                      OF PREFERRED STOCK AS 7.9% CLASS A
                     CUMULATIVE CONVERTIBLE PREFERRED STOCK


            SUNSTONE HOTEL INVESTORS, INC., a corporation organized and existing
under the laws of the State of Maryland (the "Company"), and having its
principal office in the State of Maryland at c/o The Prentice Hall Corporation
System, Inc., 11 East Chase Street, Suite 7-C, Baltimore City, Maryland 21202,
hereby certifies to the State Department of Assessments and Taxation of Maryland
(the "Department") that:

            FIRST: Pursuant to the authority expressly vested in the Board of
Directors (the "Board") of the Company by Article V, Section 5 of the Company's
Amended Articles of Incorporation filed with the Department on September 23,
1994, as amended, (the "Charter") and Section 2-105 of the Maryland General
Corporation Law ("MGCL"), the Board has, at a duly called and noticed meeting
held on August 1, 1997 at which a quorum of directors was present and acting
throughout, adopted resolutions classifying 250,000 authorized but unissued
shares of preferred stock of the Company, par value $0.01 per share ("Preferred
Stock"), as a separate class of Preferred Stock to be known as "7.9% Class A
Cumulative Convertible Preferred Stock," setting the preferences, conversion and
other rights, voting powers, restrictions, limitations as to dividends and other
distributions, qualifications and terms and conditions of redemption of the 7.9%
Class A Cumulative Convertible Preferred Stock, as set forth in Article SECOND
of these Articles Supplementary, and authorizing the issuance of up to 250,000
shares of 7.9% Class A Cumulative Convertible Preferred Stock.

            SECOND: The class of Preferred Stock of the Company created by the
resolutions duly adopted by the Board and referred to in these Articles
Supplementary shall have the following designation, number of shares, powers,
rights, preferences, qualifications, limitations and restrictions, as to
dividends, voting rights, conversion, terms and conditions of redemption,
liquidation and other terms and conditions.

            1. Designation and Number. A class of Preferred Stock of the Company
designated as "7.9% Class A Cumulative Preferred Stock" (the "Class A Preferred
Stock") is hereby established. The number of shares of Class A Preferred Stock
shall be 250,000.

            2. Maturity. The Class A Preferred Stock has no stated maturity and
will not be subject to any sinking fund or a mandatory redemption.

            3. Other Classes or Series of Preferred Stock. The Board is hereby
authorized to fix or alter the powers, rights, designations, preferences,
qualifications, limitations




                               Page 104 of 139
<PAGE>   2
and restrictions granted to or imposed upon additional classes of Preferred
Stock, and the number of shares constituting any such class and the designation
thereof, or of any of them. Subject to compliance with applicable protective
voting rights which may be granted to any class of Preferred Stock in Articles
Supplementary or to the Class A Preferred Stock ("Protective Provisions"), but
notwithstanding any other rights of the Preferred Stock or any class thereof,
the powers, rights, designations, preferences, qualifications, limitations and
restrictions of any such additional class may be subordinated to, pari passu
with (including, without limitation, inclusion in provisions with respect to
liquidation and acquisition preferences, redemption and/or approval of matters
by vote or written consent), or senior to any of those of any present or future
class of Preferred or Common Stock. Subject to compliance with applicable
Protective Provisions and these Articles Supplementary, the Board is also
authorized to increase or decrease the number of shares of any class (including
the Class A Preferred Stock), prior or subsequent to the issue of that class,
but not below the number of shares of such class then outstanding. In case the
number of shares of any class shall be so decreased, the shares constituting
such decrease shall resume the status which they had prior to the adoption of
the resolution originally fixing the number of shares of such class.

            4. Dividend Provisions. Subject to the rights of classes of
Preferred Stock which may from time to time come into existence in compliance
with Section 9, the holders of shares of Class A Preferred Stock shall be
entitled to receive for each share of Class A Preferred Stock cash dividends,
out of any assets legally available therefor, prior and in preference to any
declaration or payment of any cash dividend on the Common Stock of the Company,
at the greater of (i) 7.9% of the Original Class A Issue Price (as defined
below) (as adjusted for any stock dividends, combinations or splits with respect
to such shares) per share per annum or (ii) the product of the dividend or other
distribution paid by the Company for the quarter in question on each share of
the Common Stock (including all regular and special dividends and distributions)
multiplied by the number of shares of Common Stock into which such shares of
Class A Preferred Stock could be converted pursuant to subsection 7(a) below.
All such dividends shall be declared and paid quarterly in arrears
contemporaneously with payment of the dividends or other distributions on the
Common Stock and with the same record date for determining holders entitled to
receive such dividend as the corresponding record date on the Common Stock;
provided that if no dividends or other distributions are declared and paid on
the Common Stock for 150 days, a cash dividend for such quarter will be declared
and paid to the holders of shares of Class A Preferred Stock in accordance with
clause (i) on such 150th day. The determination of whether the amount of the
quarterly dividend on the Class A Preferred Stock will be established pursuant
to clause (i) or clause (ii) of this Section 4 will be made for each three-month
period ending each March 31, June 30, September 30 or December 31 and the
determination of whether clause (i) or clause (ii) is greater shall be made
solely on the basis of the dividends paid or to be paid on the Common Stock
during such quarterly period. Such dividends shall accrue on each share of Class
A Preferred Stock from the initial date of issuance of such share, and shall
accrue from day to day, whether or not earned or declared. Such dividends shall
be cumulative so that, except as provided below, if such dividends in respect of
any previous or current annual dividend period, at the annual rate specified
above, shall not have



                                      2




                               Page 105 of 139
<PAGE>   3
been paid the deficiency shall first be fully paid before any dividend or other
distribution shall be paid on or declared and set apart for the Common Stock. If
any dividend is not paid when due, interest shall accrue on such unpaid dividend
at the rate of 7.9% per annum compounded quarterly from the date that such
dividend was due to the date such dividend is paid. Cumulative dividends with
respect to a share of Class A Preferred Stock with a record date for payment
prior to the Conversion Date or which have accrued and remain unpaid for any
prior quarterly dividend period shall, upon conversion of such share to Common
Stock, be paid to the holder of such share. Except as provided in the
immediately preceding sentence, cumulative dividends with respect to a share of
Class A Preferred Stock which are accrued shall, upon conversion of such share
to Common Stock, not then or thereafter be paid and shall cease to be accrued,
payable and/or in arrears.

            In the event that the Company has failed to pay when due any
dividend on the Class A Preferred Stock then, until such dividend has been paid
in full, neither the Company nor any corporation, partnership, limited liability
company or other entity directly or indirectly controlled by the Company will
redeem, purchase or otherwise acquire any shares of Common Stock.

            Any dividend or distribution which is declared by the Company and
payable with assets of the Company other than cash shall be governed by the
provisions of subsections 7(d)(i) and 7(e), as applicable, of these Articles
Supplementary.

            5.    Liquidation Preference.

                  (a) In the event of any liquidation, dissolution or winding up
of the Company, either voluntary or involuntary, subject to the rights of
classes of Preferred Stock that may from time to time come into existence in
compliance with Section 9, the holders of Class A Preferred Stock shall (unless
such shares of Class A Preferred Stock are converted into shares of Common Stock
pursuant to Section 7 hereof) be entitled to receive, prior and in preference to
any distribution of any of the assets of the Company to the holders of Common
Stock by reason of their ownership thereof, an amount per share equal to the sum
of (i) $100.00 for each outstanding share of Class A Preferred Stock (the
"Original Class A Issue Price") (as adjusted for any stock dividends,
combinations or splits with respect to such shares) and (ii) an amount equal to
accrued but unpaid dividends on each such share to the date of dissolution,
liquidation or winding up (collectively, the "Liquidation Preference"). If upon
the occurrence of such event, the assets and funds thus distributed among the
holders of the Class A Preferred Stock shall be insufficient to permit the
payment to such holders of the full aforesaid preferential amounts, then,
subject to the rights of classes of Preferred Stock that may from time to time
come into existence in compliance with Section 9, the entire assets and funds of
the Company legally available for distribution shall be distributed ratably
among the holders of the Class A Preferred Stock in proportion to the amount of
such stock owned by each such holder.

<PAGE>   4
                  (b) Upon the completion of the distribution required by
subsection (a) of this Section 5 and any other distribution that may be required
with respect to classes of Preferred Stock that may from time to time come into
existence in compliance with Section 9, if assets remain in the Company, the
holders of the Common Stock of the Company shall receive all of the remaining
assets of the Company.

                  (c)(i) For purposes of this Section 5, a liquidation,
dissolution or winding up of the Company shall be deemed to be occasioned by, or
to include (A) the acquisition of a majority of the beneficial voting control of
the Company by another entity by means of any transaction or series of related
transactions (including, without limitation, any reorganization, merger or
consolidation) unless, in the case of any acquisition of the Company to which
the Company is not a party, the holders of a majority of the outstanding shares
of Class A Preferred Stock determines otherwise within 15 days of receiving
notice of such event or (B) a sale of all or substantially all of the assets of
the Company; unless the Company's shareholders of record as constituted
immediately prior to such acquisition or sale will, immediately after such
acquisition or sale (by virtue of securities issued as consideration for the
Company's acquisition or sale or otherwise) hold at least 50% of the voting
power of the surviving or acquiring entity.

                        (ii) In any of such events, if the consideration
received by the Company is other than cash, its value will be deemed its fair
market value.

                              (A) The method of valuation of securities not
subject to investment letter or other similar restrictions on free marketability
covered by subparagraph (B) below shall be as follows:

                                    (1) If traded on a securities exchange or
through the Nasdaq National Market, the value shall be deemed to be the average
of the closing prices of the securities on such exchange over the thirty-day
period ending three (3) days prior to the closing;

                                    (2) If actively traded over-the-counter, the
value shall be deemed to be the average of the closing bid or sale prices
(whichever is applicable) over the thirty-day period ending three (3) days prior
to the closing; and

                                    (3) If there is no active public trading
market, the value shall be the fair market value thereof, as mutually determined
by the Company and the holders of at least a majority of the voting power of all
then outstanding shares of Class A Preferred Stock.

                              (B) The method of valuation of securities subject
to investment letter or other restrictions on free marketability (other than
restrictions arising solely by virtue of a shareholder's status as an affiliate
or former affiliate) shall be to make an appropriate discount from the market
value determined as above in subparagraph (A) (1), (2)



                                      4




                               Page 107 of 139
<PAGE>   5
or (3) to reflect the approximate fair market value thereof, as mutually
determined by the Company and the holders of at least a majority of the voting
power of all then outstanding shares of Class A Preferred Stock.

                              (C) The fair market value of any other property or
assets shall be mutually determined by the Company and the holders of at least a
majority of the voting power of all then outstanding shares of Class A Preferred
Stock.

                        (iii) In the event the requirements of this subsection
3(c) are not complied with, the Company shall forthwith either:

                              (A) cause such closing to be postponed until such
time as the requirements of this subsection 5(c) have been complied with; or

                              (B) cancel such transaction, in which event the
powers, rights, designations and preferences of the holders of the Class A
Preferred Stock shall revert to and be the same as such powers, rights,
designations and preferences existing immediately prior to the date of the first
notice referred to in subsection 5(c)(iv) below.

                        (iv) The Company shall give each holder of record of
Class A Preferred Stock written notice of such impending transaction not later
than twenty (20) days prior to the shareholders' meeting called to approve such
transaction, or twenty (20) days prior to the closing of such transaction,
whichever is earlier, and shall also notify such holders in writing of the final
approval of such transaction (in either instance a "Liquidation Notice"). The
first of such notices shall describe the material terms and conditions of the
impending transaction and the provisions of this Section 5, and the Company
shall thereafter give such holders prompt notice of any material changes. The
transaction shall in no event take place sooner than twenty (20) days after the
Company has given the first notice provided for herein or sooner than ten (10)
days after the Company has given notice of any material changes provided for
herein; provided, however, that such periods may be shortened upon the written
consent of the holders of Class A Preferred Stock that are entitled to such
notice rights or similar notice rights and that represent at least a majority of
the voting power of all then outstanding shares of such Class A Preferred Stock.

            6.    Redemption.

                  (a) Subject to the rights of classes of Preferred Stock which
may from time to time come into existence in compliance with Section 9, on or at
any time and from time to time after October 15, 2002 (each a "Class A
Redemption Date"), the Company may at any time it may lawfully do so, at the
option of the Board, redeem in whole or in part the Class A Preferred Stock by
paying in cash therefor an amount per share equal to the Redemption Percentage
(as defined below) of the Original Class A Issue Price (as adjusted for any
stock dividends, combinations or splits with respect to such shares) plus all
accrued but unpaid



                                      5




                               Page 108 of 139
<PAGE>   6
dividends on such shares (the "Class A Redemption Price"). Any redemption
effected pursuant to this subsection (6)(a) shall be made on a pro rata basis
among the holders of the Class A Preferred Stock in proportion to the number of
shares of Class A Preferred Stock then held by them. As used herein the
"Redemption Percentage" shall mean the percentage specified in the following
table:

      Redemption Date                           Redemption Percentage (%)

       October 15, 2002 to October 14, 2003            105
       October 15, 2003 to October 14, 2004            104
       October 15, 2004 to October 14, 2005            103
       October 15, 2005 to October 14, 2006            102
       October 15, 2006 to October 14, 2007            101
       October 15, 2007 and thereafter                 100

                  (b) As used herein and in subsections (6)(c) and (d) below,
the term "Redemption Date" shall refer to each "Class A Redemption Date" and the
term "Redemption Price" shall refer to each "Class A Redemption Price." Subject
to the rights of classes of Preferred Stock which may from time to time come
into existence in compliance with Section 9, at least thirty (30) but no more
than forty-five (45) days prior to each Redemption Date, written notice shall be
mailed, first class postage prepaid, to each holder of record (at the close of
business on the business day next preceding the day on which notice is given) of
the Class A Preferred Stock to be redeemed, at the address last shown on the
records of the Company for such holder, notifying such holder of the redemption
to be effected, specifying the number of shares to be redeemed from such holder,
the Redemption Date, the Redemption Price, the place at which payment may be
obtained and calling upon such holder to surrender to the Company, in the manner
and at the place designated, his, her or its certificate or certificates
representing the shares to be redeemed (the "Redemption Notice"). Except as
provided in subsection (6)(c), on or after the Redemption Date, each holder of
Series A Preferred Stock to be redeemed shall surrender to the Company the
certificate or certificates representing such shares, in the manner and at the
place designated in the Redemption Notice, and thereupon the Redemption Price of
such shares shall be paid to the order of the person whose name appears on such
certificate or certificates as the owner thereof and each surrendered
certificate shall be cancelled. In the event less than all the shares
represented by any such certificate are redeemed, a new certificate shall be
issued representing the unredeemed shares.

                  (c) From and after the Redemption Date, unless there shall
have been a default in payment of the Redemption Price, all rights of the
holders of shares of Class A Preferred Stock designated for redemption in the
Redemption Notice as holders of Class A Preferred Stock (except the right to
receive the Redemption Price without interest upon surrender of their
certificate or certificates) shall cease with respect to such shares, and such
shares shall not thereafter be transferred on the books of the Company or be
deemed to be outstanding for any purpose whatsoever. Subject to the rights of
classes of Preferred Stock which may from



                                      6




                               Page 109 of 139
<PAGE>   7
time to time come into existence in compliance with Section 9, if the funds of
the Company legally available for redemption of shares of Class A Preferred
Stock on any Redemption Date are insufficient to redeem the total number of
shares of Class A Preferred Stock to be redeemed on such date, those funds which
are legally available will be used to redeem the maximum possible number of such
shares ratably among the holders of such shares to be redeemed based upon their
holdings of Class A Preferred Stock. The shares of Class A Preferred Stock not
redeemed shall remain outstanding and entitled to all the rights and preferences
provided herein. Subject to the rights of classes of Preferred Stock which may
from time to time come into existence in compliance with Section 9, at any time
thereafter when additional funds of the Company are legally available for the
redemption of shares of Class A Preferred Stock, such funds will immediately be
used to redeem the balance of the shares which the Company has become obliged to
redeem on any Redemption Date but which it has not redeemed.

                  (d) On or prior to each Redemption Date, the Company may
deposit the Redemption Price of all shares of Class A Preferred Stock designated
for redemption in the Redemption Notice, and not yet redeemed or converted, with
a bank or trust corporation having aggregate capital and surplus in excess of
$100,000,000 as a trust fund for the benefit of the respective holders of the
shares designated for redemption and not yet redeemed, with irrevocable
instructions and authority to the bank or trust corporation to publish the
notice of redemption thereof and pay the Redemption Price for such shares to
their respective holders on or after the Redemption Date, upon receipt of
notification from the Company that such holder has surrendered his, her or its
share certificate to the Company pursuant to subsection (6)(b) above. As of the
date of any such deposit (even if prior to the Redemption Date), the deposit
shall constitute full payment of the shares to the holders, and from and after
the date of the deposit the shares so called for redemption shall be redeemed
and shall be deemed to be no longer outstanding, and the holders thereof shall
cease to be shareholders with respect to such shares and shall have no rights
with respect thereto except the rights to receive from the bank or trust
corporation payment of the Redemption Price of the shares, without interest,
upon surrender of their certificates therefor, and the right to convert such
shares as provided in Section 5 hereof. Such instructions shall also provide
that any monies deposited by the Company pursuant to this subsection (6)(d) for
the redemption of shares thereafter converted into shares of the Company's
Common Stock pursuant to Section 7 hereof prior to the Redemption Date shall be
returned to the Company forthwith upon such conversion. The balance of any
monies deposited by the Company pursuant to this subsection (6)(d) remaining
unclaimed at the expiration of two (2) years following the Redemption Date shall
thereafter be returned to the Company upon its request expressed in a resolution
of its Board.

            7. Conversion. The holders of the Class A Preferred Stock shall have
conversion rights as follows (the "Conversion Rights"):

                  (a) Right to Convert. Each share of Class A Preferred Stock
shall be convertible, at the option of the holder thereof, at any time after the
date of issuance of such share and on or prior to the fifth day prior to the
Redemption Date or the closing of any



                                      7




                               Page 110 of 139
<PAGE>   8
transaction involving the liquidation, dissolution or winding up of the Company,
if any, as may have been fixed in any Redemption Notice or Liquidation Notice
with respect to the Class A Preferred Stock, at the office of the Company or any
transfer agent for such stock, into such number of fully paid and nonassessable
shares of Common Stock as is determined by dividing the Original Class A Issue
Price by the Conversion Price applicable to such share, determined as hereafter
provided, in effect on the date the certificate is surrendered for conversion.
The initial Conversion Price per share for shares of Class A Preferred Stock
shall be $14.7093; provided, however, if after August 4, 1997 and prior to the
filing date of these Articles Supplementary, any event occurs that would result
in an adjustment to the Conversion Price if such event occurred after the date
of issue, the initial Conversion Price shall be correspondingly adjusted to
reflect such change; and provided further, however, that the Conversion Price
for the Class A Preferred Stock shall be subject to adjustment as set forth in
subsection 7(d) after the date of issuance.

                  (b)   Automatic Conversion.  [Intentionally Omitted]

                  (c) Mechanics of Conversion. Before any holder of Class A
Preferred Stock shall be entitled to convert the same into shares of Common
Stock, such holder shall surrender the certificate or certificates therefor,
duly endorsed, at the office of any transfer agent of the Company for the Class
A Preferred Stock, and shall give written notice to the Company at its principal
corporate office, of the election to convert the same and shall state therein
the name or names in which the certificate or certificates for shares of Common
Stock are to be issued. The Company shall, as soon as practicable thereafter,
issue and deliver at such office to such holder of Class A Preferred Stock, or
to the nominee or nominees of such holder, a certificate or certificates for the
number of shares of Common Stock to which such holder shall be entitled as
aforesaid. Such conversion shall be deemed to have been made immediately prior
to the close of business on the date of such surrender of the shares of Class A
Preferred Stock to be converted (the "Conversion Date"), and the person or
persons entitled to receive the shares of Common Stock issuable upon such
conversion shall be treated for all purposes as the record holder or holders of
such shares of Common Stock as of the Conversion Date. The holder of record of
shares of Class A Preferred Stock on a dividend record date who surrenders such
shares for conversion during the period between a dividend record date and the
corresponding dividend payment date shall be entitled to receive the dividend on
such dividend payment date notwithstanding the prior conversion of such shares.

                  (d) Conversion Price Adjustments of Preferred Stock for
Certain Splits and Combinations. The Conversion Price of the Class A Preferred
Stock shall be subject to adjustment from time to time as follows:

                        (i) In the event the Company should at any time or from
time to time after the date upon which any shares of Class A Preferred Stock
were first issued (the "Purchase Date") fix a record date for the effectuation
of a split or subdivision of the outstanding shares of Common Stock or the
determination of holders of Common Stock entitled to receive



                                      8




                               Page 111 of 139
<PAGE>   9
a dividend or other distribution payable in additional shares of Common Stock or
other securities or rights convertible, exchangeable or exercisable into, or
entitling the holder thereof to receive directly or indirectly, additional
shares of Common Stock (hereinafter referred to as "Common Stock Equivalents"),
without payment of any consideration by such holder for the additional shares of
Common Stock or the Common Stock Equivalents (including the additional shares of
Common Stock issuable upon conversion, exchange or exercise thereof), then, as
of such record date (or the date of such dividend distribution, split or
subdivision if no record date is fixed), the Conversion Price of the Class A
Preferred Stock shall be appropriately decreased so that the number of shares of
Common Stock issuable on conversion of each share of such class shall be
increased in proportion to such increase in the aggregate number of shares of
Common Stock outstanding and those issuable with respect to such Common Stock
Equivalents, with the number of shares issuable with respect to Common Stock
Equivalents determined from time to time in the manner provided for deemed
issuances in subsection 7(d)(iii) below.

                        (ii) If the number of shares of Common Stock outstanding
at any time after the Purchase Date is decreased by a combination of the
outstanding shares of Common Stock, then, following the record date of such
combination, the Conversion Price for the Class A Preferred Stock shall be
appropriately increased so that the number of shares of Common Stock issuable on
conversion of each share of such class shall be decreased in proportion to such
decrease in the aggregate number of shares of Common Stock outstanding.

                        (iii) In the case of the issuance (whether before, on or
after the Purchase Date) of Common Stock Equivalents, the following provisions
shall apply for all purposes of subsection 7(d)(i):

                              (A) The aggregate maximum number of shares of
Common Stock deliverable upon conversion of or in exchange (to the extent then
convertible or exchangeable) for any such convertible or exchangeable securities
or upon the exercise of options to purchase or rights to subscribe for such
convertible or exchangeable securities and subsequent conversion or exchange
thereof shall be deemed to have been issued at the time such securities were
issued or such options or rights were issued and for a consideration equal to
the consideration, if any, received by the Company for any such securities and
related options or rights (excluding any cash received on account of accrued
interest or accrued dividends), plus the minimum additional consideration, if
any, to be received by the Company upon the conversion or exchange of such
securities or the exercise of any related options or rights.

                              (B) In the event of any change in the number of
shares of Common Stock deliverable or in the consideration payable to the
Company upon exercise of such options or rights or upon conversion of or in
exchange for such convertible or exchangeable securities, including, but not
limited to, the Conversion Price of the Class A Preferred Stock, to the extent
in any way affected by or computed using such options, rights or securities,
shall be recomputed to reflect such change, but no further adjustment shall be
made for the actual



                                      9




                               Page 112 of 139
<PAGE>   10
issuance of Common Stock or any payment of such consideration upon the exercise
of any such options or rights or the conversion or exchange of such securities.

                              (C) Upon the expiration of any such options or
rights, the termination of any such rights to convert or exchange or the
expiration of any options or rights related to such convertible or exchangeable
securities, the Conversion Price of the Class A Preferred Stock, to the extent
in any way affected by or computed using such options, rights or securities or
options or rights related to such securities, shall be recomputed to reflect the
issuance of only the number of shares of Common Stock (and convertible or
exchangeable securities which remain in effect) actually issued upon the
exercise of such options or rights, upon the conversion or exchange of such
securities or upon the exercise of the options or rights related to such
securities.

                              (D) The number of shares of Common Stock deemed
issued and the consideration deemed paid therefor pursuant to subsection
7(d)(iii)(A) shall be appropriately adjusted to reflect any change, termination
or expiration of the type described in either subsection 7(d)(iii)(B) or (C).

                  (e) Other Distributions. In the event the Company shall
declare or otherwise effect a dividend or distribution payable in securities of
other persons, evidences of indebtedness issued by the Company or other persons,
assets (excluding cash dividends) or Common Stock Equivalents not referred to in
subsection 7(d)(i), then, in each such case, the holders of the Class A
Preferred Stock shall be entitled to a proportionate share of any such dividend
or distribution as though they were the holders of the number of shares of
Common Stock of the Company into which their shares of Class A Preferred Stock
are convertible as of the record date fixed for the determination of the holders
of Common Stock of the Company entitled to receive such dividend or
distribution.

                  (f) Recapitalizations. If at any time or from time to time
there shall be a recapitalization of the Common Stock (other than a subdivision,
combination or merger or sale of assets transaction provided for elsewhere in
this Section 7 or Section 5), provision shall be made so that the holders of the
Class A Preferred Stock shall thereafter be entitled to receive upon conversion
of the Class A Preferred Stock the number of shares of stock or other securities
or property of the Company or otherwise, to which a holder of Common Stock
deliverable upon conversion would have been entitled on such recapitalization.
In case of any such recapitalization, the successor or acquiring corporation (if
other than the Company) shall expressly assume the due and punctual observance
and performance of each and every covenant and condition of this Agreement to be
performed and observed by the Company and all the obligations and liabilities
hereunder, subject to such modifications as may be deemed appropriate (as
determined by resolution of the Board of Directors of the Company) in order to
provide for adjustments of shares of the Common Stock issuable upon conversion
of the Class A Preferred Stock which shall be as nearly equivalent as
practicable to the adjustments provided for in subsection 7(d).



                                      10




                               Page 113 of 139
<PAGE>   11
                  (g) No Impairment. The Company will not, by amendment of its
Articles of Incorporation or through any reorganization, recapitalization,
transfer of assets, consolidation, merger, dissolution, issue or sale of
securities or any other voluntary action, avoid or seek to avoid the observance
or performance of any of the terms to be observed or performed hereunder by the
Company, but will at all times in good faith assist in the carrying out of all
the provisions of this Section 7 and in the taking of all such action as may be
necessary or appropriate in order to protect the Conversion Rights of the
holders of the Class A Preferred Stock against impairment.

                  (h)   No Fractional Shares and Certificate as to Adjustments.

                        (i) No fractional shares shall be issued upon the
conversion of any share or shares of the Class A Preferred Stock. Any fractional
interest in a share of Common Stock resulting from conversion of shares of Class
A Preferred Stock will be paid in cash (computed to the nearest cent) based on
the fair market value (as defined in subsection 5(c)(ii) above) of the Common
Stock. If more than one share of Class A Preferred Stock is surrendered for
conversion at substantially the same time by the same holder, the number of full
shares of Common Stock issuable upon the conversion will be computed on the
basis of all the shares of Class A Preferred Stock surrendered at that time by
that holder.

                        (ii) Upon the occurrence of each adjustment or
readjustment of the Conversion Price of Class A Preferred Stock pursuant to this
Section 7, the Company, at its expense, shall promptly compute such adjustment
or readjustment in accordance with the terms hereof and prepare and furnish to
each holder of Class A Preferred Stock a certificate setting forth such
adjustment or readjustment and showing in detail the facts upon which such
adjustment or readjustment is based. The Company shall, upon the written request
at any time of any holder of Class A Preferred Stock, furnish or cause to be
furnished to such holder a like certificate setting forth (A) such adjustment
and readjustment, (B) the Conversion Price for such class of Preferred Stock at
the time in effect, and (C) the number of shares of Common Stock and the amount,
if any, of other property which at the time would be received upon the
conversion of a share of Class A Preferred Stock.

                  (i) Notices of Record Date. In the event of any taking by the
Company of a record of the holders of any class of securities for the purpose of
determining the holders thereof who are entitled to receive any dividend (other
than a cash dividend) or other distribution, any right to subscribe for,
purchase or otherwise acquire any shares of stock of any class or any other
securities or property, or to receive any other right, the Company shall mail to
each holder of Class A Preferred Stock, at least 20 days prior to the date
specified therein, a notice specifying the date on which any such record is to
be taken for the purpose of such dividend, distribution or right, and the amount
and character of such dividend, distribution or right.


                                      11

                  (j)   Reservation of Stock Issuable Upon Conversion.

                        (i) The Company shall at all times reserve and keep
available out of its authorized but unissued shares of Common Stock, solely for
the purpose of effecting the conversion of the shares of the Class A Preferred
Stock, such number of its shares of Common Stock as shall from time to time be
sufficient to effect the conversion of all outstanding shares of the Class A
Preferred Stock; and if at any time the number of authorized but unissued shares
of Common Stock shall not be sufficient to effect the conversion of all then
outstanding shares of the Class A Preferred Stock, in addition to such other
remedies as shall be available to the holder of such Preferred Stock, the
Company will use its best efforts to take such corporate action as may, in the
opinion of its counsel, be necessary to increase its authorized but unissued
shares of Common Stock to such number of shares as shall be sufficient for such
purposes, including, without limitation, engaging in best efforts to obtain the
requisite shareholder approval of any necessary amendment to its Articles of
Incorporation.

                        (ii) For the purposes of this subsection 7(j)(i), the
number of shares of Common Stock which the Company would be required to deliver
upon the conversion of all the outstanding shares of Class A Preferred Stock
will be computed as if at the time of the computation all the outstanding shares
of Class A Preferred Stock were held by a single holder.

                        (iii) If any shares of Common Stock required to be
reserved for purposes of conversion of the Class A Preferred Stock hereunder
require registration with or approval of any governmental authority under any
Federal or State law before such shares may be issued upon conversion, the
Company shall in good faith and as expeditiously as possible endeavor to cause
such shares to be duly registered or approved, as the case may be. The Company
will seek to list the shares of Common Stock required to be delivered upon
conversion of the Class A Preferred Stock, prior to the delivery, upon each
national securities exchange, if any, upon which the outstanding shares of
Common Stock are listed at the time of delivery.

                  (k) Taxes. The Company will pay any documentary stamp of
similar issue or transfer taxes payable in respect of the issue or delivery of
shares of Common Stock on conversion of Class A Preferred Stock; provided,
however, that the Company will not be required to pay any tax which may be
payable in respect of any transfer involved in the issue or delivery of shares
of Common Stock in a name other than that of the holder of record of the Class A
Preferred Stock to be converted and no such issue or delivery will be made
unless and until the person requesting the issue or delivery has paid to the
Company the amount of any such tax or has established, to the satisfaction of
the Company, that the tax has been paid.

                  (l) Notices. Any notice required by the provisions of this
Section 5 to be given to the holders of shares of Class A Preferred Stock shall
be deemed given if deposited in the United States mail, postage prepaid, and
addressed to each holder of record at such holder's address appearing on the
books of the Company.




                                      12

            8.    Voting Rights.

                  (a) Except as required by law or by the provisions of
subsections 6(b) and (c), the holders of each share of Class A Preferred Stock
shall have the right to one vote for each share of Common Stock into which such
holder's shares of Class A Preferred Stock could then be converted, and with
respect to such vote, such holder shall have full voting rights and powers equal
to the voting rights and powers of the holders of Common Stock, and shall be
entitled, notwithstanding any provision hereof, to notice of any shareholders'
meeting in accordance with the bylaws of the Company, and shall be entitled to
vote, together with holders of Common Stock as a single class, with respect to
any matter submitted to a vote of holders of Common Stock. Fractional votes
shall not, however, be permitted and any fractional voting rights available on
an as-converted basis (after aggregating all shares into which shares of Class A
Preferred Stock held by each holder could be converted) shall be rounded to the
nearest whole number (with one-half being rounded upward).

                  (b) In the event the Company fails to pay dividends to the
holders of Class A Preferred Stock contemporaneously with dividends paid to the
holders of Common Stock for two consecutive quarters or, in the event no
dividends have been paid or declared on the Common Stock, by the 150th day
thereafter, in either event in accordance with Section 2 hereof, then and until
such accrued but unpaid dividends shall have been paid in full, the holders of
Class A Preferred Stock shall, voting separately as one class, have the
exclusive and special right to elect one (1) director to the Board of the
Company, provided, however, that if, at such time, the number of directors of
the Company, as fixed by the shareholders or the Board of Directors of the
Company, is the maximum number permitted by the Charter of the Company, the
Company shall use its best efforts to cause its Charter to be amended to
increase the maximum number of directors of the Company so as to allow for the
election on one (1) director by the holders of the Class A Preferred Stock, and
the right of the holders of the Class A Preferred stock to elect one (1)
director in such instance will be deferred until such time as the Charter of the
Company is amended to appropriately increase the maximum number of directors
permitted thereunder. Once all accrued but unpaid dividends on the Class A
Preferred Stock shall have been paid in full, the holders of Class A Preferred
Stock shall no longer be entitled to a special right to elect a director under
this subsection 8(b) but shall instead vote together with the holders of Common
Stock in the election of directors in accordance with subsection 8(a) above, and
any such director then in office shall be deemed to have resigned effective with
such payment. In any election of directors pursuant to this subsection 8(b),
each holder of shares of Class A Preferred Stock shall be entitled to one vote
for each share of Common Stock into which such holder's Class A Preferred Stock
is convertible as determined in accordance with subsection 8(a) above. The
special and exclusive voting right of the holders of the Class A Preferred
Stock, voting separately as one class, contained in this subsection 8(b) may be
exercised either at a special meeting of the holders of Class A Preferred Stock
called as provided below, or at any annual or special meeting of the
shareholders of the Company, or by unanimous written consent of such holders in
lieu of a meeting. The director to be elected by the holders of the Class A
Preferred Stock, voting separately as one class, pursuant to this subsection
8(b),



                                      13




                               Page 116 of 139
<PAGE>   14
shall serve for terms extending from the date of his election and qualification
until the earlier of (i) the next succeeding annual meeting of shareholders,
(ii) his successor has been elected and qualified or (iii) all such accrued but
unpaid dividends on the Class A Preferred Stock shall have been paid in full.

            (c) If at any time any directorship to be filled by the holders of
Class A Preferred Stock, voting separately as one class pursuant to subsection
8(b) above, has been vacant for a period of ten (10) days, the Secretary of the
Company shall, upon the written request of the holders of record of shares
representing at least ten percent (10%) of the voting power of the Class A
Preferred Stock then outstanding, call a special meeting of the holders of Class
A Preferred Stock for the purpose of electing the director to fill such vacancy.
Such meeting shall be held at the earliest practicable date at such place as is
specified in or determined in accordance with the Bylaws of the Company. If such
meeting shall not be called by the Secretary of the Company within ten (10) days
after personal service of said written request on him, then the holders of
record of shares representing at least ten percent (10%) of the voting power of
the Class A Preferred Stock then outstanding may designate in writing one of
their number to call such meeting at the expense of the Company, and such
meeting may be called by such person so designated upon the notice required for
annual meetings of shareholders and shall be held at the place specified in the
notice. Any holder of the Class A Preferred Stock so designated shall have
access to the stock books of the Company relating to the Class A Preferred Stock
for the purpose of calling a meeting of the shareholders pursuant to these
provisions.

            9. Protective Provisions. Subject to the rights of classes of
Preferred Stock which may from time to time come into existence in compliance
with Section 9, so long as any shares of Class A Preferred Stock are
outstanding, the Company shall not (including through a merger or consolidation
with another corporation or otherwise), without first obtaining the approval (by
vote or written consent, as provided by law) of the holders of at least a
majority of the then outstanding shares of Class A Preferred Stock:

                  (a) alter or change the rights, preferences or privileges of
the shares of Class A Preferred Stock so as to affect adversely the shares;

                  (b) increase or decrease (other than by redemption or
conversion) the total number of authorized shares of Class A Preferred Stock;

                  (c) authorize or issue, or obligate itself to issue, any other
equity security, including any other security convertible into or exercisable
for any equity security having a preference over, or being on a parity with, the
Class A Preferred Stock with respect to voting, dividends or upon liquidation.

            10. Status of Converted or Redeemed Stock. In the event any shares
of Class A Preferred Stock shall be redeemed or converted pursuant to Section 6
or Section 7 hereof, the shares so converted or redeemed shall be cancelled and
shall not be issuable by the Company.

SUNSTONE HOTEL INVESTORS, INC. ("Sunstone"), a Maryland corporation, WESTBROOK
REAL ESTATE FUND I, L.P., a Delaware limited partnership ("Westbrook Fund") and

and the Funds to consummate the transactions contemplated by the Stock Purchase
Agreement that this Registration Rights Agreement be executed and delivered by
Sunstone and the Funds.

            NOW, THEREFORE, in consideration of the premises and mutual
covenants and agreements herein contained the parties hereto agree as follows:


                                   AGREEMENT


            1. Definitions. As used in this Agreement, the following capitalized
terms shall have the following respective meanings:

            "Common Stock" shall mean the common stock, par value $0.01 per
      share, of Sunstone and its successors.

            "Demand Party" shall mean (a) Westbrook Fund, (b) Westbrook

      limitation, any present or future general or limited partner of either of
      the Funds, or any general or limited partner of any general or limited

      hereunder; provided that to be a Demand Party under clause (c), a Holder
      or



                                     -1-




                               Page 120 of 139

      amended, or any similar federal statute, and the rules and regulations of
      the SEC thereunder, all as the same shall be in effect from time to time,

      a reference to the comparable section, if any, of any such similar federal
      statute.

            "Holder" shall mean each of the Funds, and any other holder of
      Registrable Securities (including any direct or indirect transferees of
      the Funds) who agree in writing to be bound by the provisions of this
      Agreement.

            "Initial Lock-Up Period" shall have the meaning set forth in the
      Stock Purchase Agreement.

            "Person" shall mean any individual, partnership, joint venture,
      corporation, trust, unincorporated organization, government or any

      issued or issuable upon conversion of the Convertible Preferred Stock
      issued to the Funds pursuant to the Stock Purchase Agreement, and (3) any

      or stock split or other distribution, recapitalization or reclassification
      with respect to, or in exchange for, or in replacement of, any other
      Registrable Securities. As to any particular Registrable Securities, once
      issued, such Registrable Securities shall cease to be Registrable
      Securities when (i) a registration statement with respect to the sale by
      the Holder of such securities shall have become effective under the
      Securities Act and such securities shall have been disposed of in
      accordance with such registration statement, (ii) such securities shall

      provision) under the Securities Act, (iii) such securities shall have been
      otherwise transferred, new certificates for such securities not bearing a
      legend restricting further transfer shall have been delivered by Sunstone

      or any state securities or blue sky law then in force, or (iv) such
      securities shall have ceased to be outstanding.

            "Registration Expenses" shall mean any and all expenses incident to
      performance of or compliance with this Agreement, including, without

      Securities Dealers, Inc. (the "NASD") registration and filing fees
      (including, if applicable, the fees and expenses of any "qualified
      independent underwriter," as such term is defined in Schedule E to the



                                       -2-




                               Page 121 of 139
<PAGE>   3
      By-laws of the NASD, and of its counsel), (ii) all fees and expenses of
      complying with securities or blue sky laws (including the reasonable fees
      and disbursements of counsel for the underwriters, if any, in connection
      with blue sky qualifications of the Registrable Securities), (iii) all
      printing, messenger and delivery expenses, (iv) all fees and expenses
      incurred in connection with the listing of the Registrable Securities on
      the New York Stock Exchange or on any securities exchange pursuant to
      clause (viii) of Section 5, (v) the fees and disbursements of one counsel
      for Sunstone and of its independent public accountants, including the
      expenses of any special audits and/or "cold comfort" letters required by
      or incident to such performance and compliance, (vi) the reasonable fees
      and disbursements of one counsel selected pursuant to Section 8 hereof by
      the Holders of the Registrable Securities being registered to represent
      such Holders in connection with each such registration, (vii) any fees and
      disbursements of underwriters, if any, customarily paid by the issuers or
      sellers of securities, including liability insurance if Sunstone so
      desires or if the underwriters so require, and the reasonable fees and
      expenses of any special experts retained in connection with the requested
      registration, but excluding underwriting discounts and commissions,
      transfer taxes, and (viii) other reasonable out-of-pocket expenses of
      Holders (provided that such expenses shall not include expenses of counsel
      other than those provided for in clause (vi) above).

            "Securities Act" shall mean the Securities Act of 1933, as amended,
      or any similar federal statute and the rules and regulations of the SEC
      thereunder, all as the same shall be in effect from time to time, and a
      reference to a particular section thereof shall be deemed to include a
      reference to the comparable section, if any, of any such similar federal
      statute.

            "SEC" shall mean the Securities and Exchange Commission or any other
      federal agency at the time administering the Securities Act or the
      Exchange Act.

            2. Incidental Registrations. (a) Right to Include Common or Common
Equivalent Registrable Securities. If Sunstone at any time after the Initial
Lock-Up Period proposes to register its Common Stock under the Securities Act
(other than a registration on Form S-4 or S-8, or any successor or other forms
promulgated for similar purposes), for sale for its own account, in a manner
which would permit registration of Registrable Securities for sale to the public
under the Securities Act, it will, at each such time, give prompt written notice
to all Holders of Registrable Securities of its intention to do so and of such
Holders' rights under this Section 2. Upon the written request of any such
Holder made within 15 days after the receipt of any such notice (which request
shall specify the Registrable Securities intended to be disposed of by such
Holder), Sunstone will use its best efforts to effect the registration under the
Securities Act of all Registrable Securities which Sunstone has been so
requested to register by the Holders thereof, to the extent requisite to permit
the disposition of the Registrable Securities so to be registered; provided that
(i) if, at any time after giving written notice of its intention to register any
securities and prior to the effective date of the registration statement filed
in connection with such registration, Sunstone shall determine for any reason
not to proceed with the proposed registration of the securities to be sold by
it, Sunstone may, at its election, give written notice of such determination to
each Holder of Registrable Securities and,



                                     -3-




                               Page 122 of 139
<PAGE>   4
thereupon, shall be relieved of its obligation to register any Registrable
Securities in connection with such registration (but not from its obligation to
pay the Registration Expenses in connection therewith), and (ii) if such
registration involves an underwritten offering, all Holders of Registrable
Securities requesting to be included in Sunstone's registration must sell their
Registrable Securities to the underwriters selected by Sunstone on the same
terms and conditions as apply to Sunstone, with such differences, including any
with respect to indemnification and liability insurance, as may be customary or
appropriate in combined primary and secondary offerings; and provided further
that under no circumstances will the scope of any indemnification or
contribution obligations of any Holder be broader than the provisions of Section
6(b) hereof nor will the maximum liability of the Holders be greater than that
specified in Section 6 hereof. If a registration requested pursuant to this
Section 2(a) involves an underwritten public offering, any Holder of Registrable
Securities requesting to be included in such registration may elect, in writing
within seven (7) business days prior to the effective date of the registration
statement filed in connection with such registration, not to register such
securities in connection with such registration. Nothing in this Section 2(a)
shall operate to limit the right of any Holder to request the registration of
Common Stock issuable upon conversion or exercise of convertible securities held
by such Holder notwithstanding the fact that at the time of request such Holder
holds only convertible securities.

            (b) Expenses. Sunstone will pay all Registration Expenses in
connection with each registration of Registrable Securities requested pursuant
to this Section 2.

            (c) Priority in Incidental Registrations. If a registration pursuant
to this Section 2 involves an underwritten offering and the managing underwriter
advises Sunstone in writing that, in its opinion, the number of shares of Common
Stock requested to be included in such registration exceeds the number which can
be sold in such offering, so as to be likely to have an adverse effect on the
price, timing or distribution of the Common Stock offered in such offering as
contemplated by Sunstone, then Sunstone will include in such registration (i)
first, 100% of the securities Sunstone proposes to sell and (ii) second, the
number of Registrable Securities requested to be included in such registration
which, in the opinion of such managing underwriter, can be sold without having
the adverse effect referred to above, such amount to be allocated pro rata among
all requesting Holders on the basis of the relative number of shares of
Registrable Securities then held by each such Holder (provided that any shares
thereby allocated to any such Holder that exceed such Holder's request will be
reallocated among the remaining requesting Holders in like manner).

            (d) Limitations on Shelf Offerings. Notwithstanding the foregoing,
in the event that Registrable Securities have been included in a registration
effected by Sunstone pursuant to Rule 415 under the Securities Act in accordance
with this Section 2, the Holders agree that, without the prior written consent
of Sunstone, they will not effect more than one sale of Registrable Securities
pursuant to such registration in any 30-day period.

            3. Registration on Request. (a) Request by the Demand Party. At any
time after the Initial Lock-Up Period, upon the written request of the Demand
Party requesting that Sunstone effect the registration under the Securities Act
of all or part of such Demand Party's



                                     -4-




                               Page 123 of 139
<PAGE>   5
Registrable Securities and specifying the amount and intended method of
disposition thereof, Sunstone will promptly give written notice of such
requested registration to all other Holders of such Registrable Securities, and
thereupon will, as expeditiously as possible, use its best efforts to effect the
registration under the Securities Act of:

            (i) such Registrable Securities (including, if such request relates
      to a security which is convertible into shares of Common Stock, the shares
      of Common Stock issuable upon such conversion) which Sunstone has been so
      requested to register by the Demand Party; and

            (ii) all other Registrable Securities of the same class or series as
      are to be registered at the request of a Demand Party and which Sunstone
      has been requested to register by any other Holder thereof by written
      request given to Sunstone within 15 days after the giving of such written
      notice by Sunstone (which request shall specify the amount and intended
      method of disposition of such Registrable Securities),

all to the extent necessary to permit the disposition (in accordance with the
intended method thereof as aforesaid) of the Registrable Securities so to be
registered; provided, that with respect to any Demand Party, Sunstone shall not
be obligated to effect any registration of Registrable Securities under this
Section 3(a) unless such Demand Party requests that Sunstone register at least
20% of the total number of Registrable Securities then outstanding (or such
lesser percent if the anticipated aggregate offering price, net of underwriting
discounts and commissions would exceed $10,000,000); and provided, further,
that, Sunstone shall not be obligated to file a registration statement relating
to any registration request under this Section 3(a) (x) within a period of six
months after the effective date of any other registration statement relating to
any registration request under this Section 3(a) or relating to any registration
effected under Section 2 in which Registrable Securities were included in such
registration, (y) if with respect thereto the managing underwriter, the SEC, the
Securities Act or the rules and regulations thereunder, or the form on which the
registration statement is to be filed, would require the completion of an audit
other than the regular audit conducted by Sunstone at the end of its fiscal
year, in which case the filing may be delayed until the completion of such
regular audit (unless the Holders of the Registrable Securities to be registered
agree to pay the expenses of Sunstone in connection with such an audit other
than the regular audit) or (z) subject to Section 9(j)(ii), during any period of
not more than 90 days that the Company, its executive officers or directors are
precluded from selling shares of Common Stock as the result of any lock-up
restrictions imposed by any underwriter in a previous primary offering, unless
such underwriters agree otherwise. Nothing in this Section 3 shall operate to
limit the right of a Holder to request the registration of Common Stock issuable
upon conversion or exercise of convertible securities held by such Holder
notwithstanding the fact that at the time of request such Holder holds only
convertible securities.

            (b) Notwithstanding the foregoing provisions of Section 3(a),
Sunstone shall not be obligated to effect more than two demand registrations
pursuant to requests made by the Demand Holders pursuant to this Section 3. No
Holder's rights under this Section 3 shall be affected by a registration
pursuant to Section 2.



                                     -5-




                               Page 124 of 139
<PAGE>   6
            (c) Registration Statement Form. If any registration requested
pursuant to this Section 3, which is proposed by Sunstone to be effected by the
filing of a registration statement on Form S-3 (or any successor or similar
short-form registration statement), shall be in connection with an underwritten
public offering, and if the managing underwriter shall advise Sunstone in
writing that, in its opinion, the inclusion of additional information is of
material importance to the success of such proposed offering, then such
registration shall include such other information.

            (d) Expenses. Sunstone will pay all Registration Expenses in
connection with each of the registrations of each class or series of Registrable
Securities effected pursuant to this Section 3.

            (e) Effective Registration Statement. A registration requested
pursuant to this Section 3 will not be deemed to have been effected unless the
applicable registration statement has become effective; provided that if, prior
to the end of any applicable distribution period as defined in the Securities
Act, the offering of Registrable Securities pursuant to such registration is
interfered with by any stop order, injunction or other order or requirement of
the SEC or other governmental agency or court, such registration will be deemed
not to have been effected with respect to any selling Holder whose Registrable
Securities that are registered have not been fully distributed.

            (f) Selection of Underwriters. If a requested registration pursuant
to this Section 3 involves an underwritten offering, the Holders of a majority
of the shares of Registrable Securities which are held by Holders and which
Sunstone has been requested to register shall have the right to select the
investment banker or bankers and managers to administer the offering; provided,
however, that such investment banker or bankers and managers shall be reasonably
satisfactory to Sunstone.

            (g) Priority in Requested Registrations. If a requested registration
pursuant to this Section 3 involves an underwritten offering and the managing
underwriter advises Sunstone in writing that, in its opinion, the number of
shares of Common Stock requested to be included in such registration (including
securities of Sunstone which are not Registrable Securities) exceeds the number
which can be sold in such offering, Sunstone will include in such registration
only the Registrable Securities requested to be included in such registration.
In the event that the number of Registrable Securities requested to be included
in such registration exceeds the number which, in the opinion of such managing
underwriter, can be sold, the number of such Registrable Securities to be
included in such registration shall be allocated pro rata among all requesting
Holders on the basis of the relative number of shares of Registrable Securities
then held by each such Holder; provided that any shares thereby allocated to any
such Holder that exceed such Holder's request shall be reallocated among the
remaining requesting Holders in like manner; provided, further that if any such
exclusion causes less than 90% of the number of shares of Registrable Securities
as to which registration was requested by the Holders to be registered, such
registration shall not constitute a request for registration under Section 3(b).
In the event that the number of Registrable Securities requested to be included
in such registration is less than the number which, in the opinion of the
managing underwriter, can



                                     -6-




                               Page 125 of 139
<PAGE>   7
be sold, Sunstone may include in such registration up to the number of shares of
Common Stock that, in the opinion of the underwriter, can be sold.

            (h) Additional Rights. If Sunstone at any time grants to any other
holders of Common Stock, or Common Stock issuable upon conversion, exchange or
exercise of a security, any rights to request Sunstone to effect the
registration under the Securities Act of any such shares of Common Stock on
terms more favorable to such holders than the terms set forth in this Section 3,
the terms of this Section 3 shall be deemed amended or supplemented to the
extent necessary to provide the Holders such more favorable rights and benefits.
The provisions of this Section 3(h) will not be applicable to the registration
rights of the limited partners of Sunstone Hotel Investors, L.P. permitting them
to require Sunstone to register the shares of Common Stock into which their
partnership units are exchangeable.

            4. Stock Purchase Agreement Transfer Restrictions. Notwithstanding
anything in this Agreement to the contrary, any sales of Registrable Securities
shall be subject to the conditions set forth in Section 4.10 of the Stock
Purchase Agreement.

            5. Registration Procedures. If and whenever Sunstone is required to
use its best efforts to effect or cause the registration of any Registrable
Securities under the Securities Act as provided in this Agreement, Sunstone
will, as expeditiously as possible:

                  (a) prepare and, in any event within 120 days after the end of
      the period within which a request for registration may be given to
      Sunstone, file with the SEC a registration statement with respect to such
      Registrable Securities and use its best efforts to cause such registration
      statement to become effective; provided, however, that Sunstone may
      discontinue any registration of its securities which is being effected
      pursuant to Section 2 at any time prior to the effective date of the
      registration statement relating thereto or in accordance with Section
      3(b);

                  (b) prepare and file with the SEC such amendments and
      supplements to such registration statement and the prospectus used in
      connection therewith as may be necessary to keep such registration
      statement effective during the distribution period, in the case of a
      registration effected pursuant to Section 2, or for a period not in excess
      of 270 days (or such lesser period ending on the day after the
      distribution of all registered securities is complete) in the case of a
      registration effected pursuant to Section 3, and to comply with the
      provisions of the Securities Act, the Exchange Act and the rules and
      regulations of the SEC thereunder with respect to the disposition of all
      securities covered by such registration statement during such period in
      accordance with the intended methods of disposition by the seller or
      sellers thereof set forth in such registration statement; provided that
      before filing a registration statement or prospectus relating to the sale
      of Registrable Securities, or any amendments or supplements thereto,
      Sunstone will furnish to counsel selected pursuant to Section 8 hereof by
      the Holders of the Registrable Securities covered by such registration
      statement to represent such Holders, copies of all documents proposed to
      be filed, which documents will be subject to the



                                     -7-

<PAGE>   8
      review of such counsel within five (5) days after receipt thereof, and
      Sunstone will give reasonable consideration in good faith to any comments
      of such counsel;

                  (c) furnish to each seller of such Registrable Securities such
      number of copies of such registration statement and of each amendment and
      supplement thereto (in each case including all exhibits filed therewith,
      including any documents incorporated by reference), such number of copies
      of the prospectus included in such registration statement (including each
      preliminary prospectus and summary prospectus), in conformity with the
      requirements of the Securities Act, and such other documents as such
      seller may reasonably request in order to facilitate the disposition of
      the Registrable Securities by such seller;

                  (d) use its best efforts to register or qualify such
      Registrable Securities covered by such registration statement under such
      other securities or blue sky laws of such jurisdictions as each seller
      shall reasonably request, and do any and all other acts and things which
      may be reasonably necessary or advisable to enable such seller to
      consummate the disposition in such jurisdictions of the Registrable
      Securities owned by such seller, except that Sunstone shall not for any
      such purpose be required to qualify generally to do business as a foreign
      corporation in any jurisdiction where, but for the requirements of this
      clause (iv), it would not be obligated to be so qualified, to subject
      itself to taxation in any such jurisdiction or to consent to general
      service of process in any such jurisdiction;

                  (e) use its best efforts to cause such Registrable Securities
      covered by such registration statement to be registered with or approved
      by such other governmental agencies or authorities as may be necessary to
      enable the seller or sellers thereof to consummate the disposition of such
      Registrable Securities;

                  (f) notify promptly each seller of any such Registrable
      Securities covered by such registration statement, at any time when a
      prospectus relating thereto is required to be delivered under the
      Securities Act within the appropriate period mentioned in clause (b) of
      this Section 5, of Sunstone's becoming aware that the prospectus included
      in such registration statement, as then in effect, includes an untrue
      statement of a material fact or omits to state a material fact required to
      be stated therein or necessary to make the statements therein not
      misleading in the light of the circumstances then existing, and at the
      request of any such seller, prepare and furnish to such seller a
      reasonable number of copies of an amended or supplemental prospectus as
      may be necessary so that, as thereafter delivered to the purchasers of
      such Registrable Securities, such prospectus shall not include an untrue
      statement of a material fact or omit to state a material fact required to
      be stated therein or necessary to make the statements therein not
      misleading in the light of the circumstances then existing;

                  (g) otherwise use its best efforts to comply with all
      applicable rules and regulations of the SEC, and make available to its
      security holders, as soon as reasonably practicable (but not more than
      eighteen months) after the effective date of the registration



                                     -8-

      statement, if required, an earnings statement which shall satisfy the
      provisions of Section 11(a) of the Securities Act and the rules and
      regulations promulgated thereunder;

                  (h) (i) use its best efforts to list such Registrable
      Securities on any securities exchange on which the Common Stock is then
      listed if such Registrable Securities are not already so listed and if
      such listing is then permitted under the rules of such exchange; and (ii)
      use its best efforts to provide a transfer agent and registrar for such
      Registrable Securities covered by such registration statement not later
      than the effective date of such registration statement;

                  (i) enter into such customary agreements (including an
      underwriting agreement in customary form), which may include
      indemnification provisions in favor of underwriters and other persons in
      addition to, or in substitution for the provisions of Section 6 hereof,
      and take such other actions as sellers of a majority of shares of such
      Registrable Securities or the underwriters, if any, reasonably requested
      in order to expedite or facilitate the disposition of such Registrable
      Securities;

                  (j) to the extent permitted by the rules of the AICPA, use its
      best efforts to obtain a "cold comfort" letter or letters from Sunstone's
      independent public accountants in customary form and covering matters of
      the type customarily covered by "cold comfort" letters as the seller or
      sellers of a majority of shares of such Registrable Securities shall
      reasonably request (provided that Registrable Securities constitute at
      least 25% of the securities covered by such registration statement, unless
      such a "cold comfort" letter or letters are provided to other selling
      holders in connection with such registration); it being understood,
      however, that Sunstone will, if requested by the underwriters in any
      underwritten offering, be obligated to use its best efforts to obtain for
      such underwriters a "cold comfort" letter or letters from Sunstone's
      independent public accountants in customary form;

                  (k) make available for inspection by any seller of such
      Registrable Securities covered by such registration statement, by any
      underwriter participating in any disposition to be effected pursuant to
      such registration statement and by any attorney, accountant or other agent
      retained by any such seller or any such underwriter, all pertinent
      financial and other records, pertinent corporate documents and properties
      of Sunstone, and cause all of Sunstone's officers, directors and employees
      to supply all information reasonably requested by any such seller,
      underwriter, attorney, accountant or agent in connection with such
      registration statement;

                  (l) notify counsel (selected pursuant to Section 8 hereof) for
      the Holders of Registrable Securities included in such registration
      statement and the managing underwriter or agent, immediately, and confirm
      the notice in writing (A) when the registration statement, or any
      post-effective amendment to the registration statement, shall have become
      effective, or any supplement to the prospectus or any amendment prospectus
      shall have been filed, (B) of the receipt of any comments from the SEC,
      (C) of any request of the SEC to amend the registration statement or amend
      or supplement



                                     -9-

      the prospectus or for additional information and (D) of the issuance by
      the SEC of any stop order suspending the effectiveness of the registration
      statement or of any order preventing or suspending the use of any
      preliminary prospectus, or of the suspension of the qualification of the
      registration statement for offering or sale in any jurisdiction, or of the
      institution or threatening of any proceedings for any of such purposes;

                  (m) use reasonable efforts to prevent the issuance of any stop
      order suspending the effectiveness of the registration statement or of any
      order preventing or suspending the use of any preliminary prospectus and,
      if any such order is issued, to obtain the withdrawal of any such order at
      the earliest possible moment;

                  (n) if requested by the managing underwriter or agent or any
      Holder of Registrable Securities covered by the registration statement,
      promptly incorporate in a prospectus supplement or post-effective
      amendment such information as the managing underwriter or agent or such
      Holder reasonably requests to be included therein, including, without
      limitation, the number of Registrable Securities being sold by such Holder
      to such underwriter or agent, the purchase price being paid therefor by
      such underwriter or agent and any other terms of the underwritten offering
      of the Registrable Securities to be sold in such offering; and make all
      required filings of such prospectus supplement or post-effective amendment
      as soon as practicable after being notified of the matters incorporated in
      such prospectus supplement or post-effective amendment;

                  (o) cooperate with the Holders of Registrable Securities
      covered by the registration statement and the managing underwriter or
      agent, if any, to facilitate the timely preparation and delivery of
      certificates (not bearing any restrictive legends) representing securities
      sold under the registration statement, and enable such securities to be in
      such denominations and registered in such names as the managing
      underwriter or agent, if any, or such Holders may request;

                  (p) obtain for delivery to the Holders of Registrable
      Securities being registered and to the underwriter or agent an opinion or
      opinions of counsel for Sunstone in customary form and in form, substance
      and scope reasonably satisfactory to such Holders, underwriters or agents
      and their counsel; and

                  (q) cooperate with each seller of Registrable Securities and
      each underwriter or agent participating in the disposition of such
      Registrable Securities and their respective counsel in connection with any
      filings required to be made with the NASD.

            Sunstone may require each seller of Registrable Securities as to
which any registration is being effected to furnish Sunstone with such
information regarding such seller and pertinent to the disclosure requirements
relating to the registration and the distribution of such securities as Sunstone
may from time to time reasonably request in writing.




                                     -10-

<PAGE>   11
            Each Holder of Registrable Securities agrees that, upon receipt of
any notice from Sunstone of the happening of any event of the kind described in
clause (f) of this Section 5, such Holder will forthwith discontinue disposition
of Registrable Securities pursuant to the registration statement covering such
Registrable Securities until such Holder's receipt of the copies of the
supplemented or amended prospectus contemplated by clause (f) of this Section 5,
and, if so directed by Sunstone, such Holder will deliver to Sunstone (at
Sunstone's expense) all copies, other than permanent file copies then in such
Holder's possession, of the prospectus covering such Registrable Securities
current immediately prior to the receipt of such notice. In the event Sunstone
shall give any such notice, the period mentioned in clause (b) of this Section 5
shall be extended by the number of days during the period from and including the
date of the giving of such notice pursuant to clause (f) of this Section 5 and
including the date when each seller of Registrable Securities covered by such
registration statement shall have received the copies of the supplemented or
amended prospectus contemplated by clause (f) of this Section 5.

            In lieu of satisfying the requirements of Sections 2 or 3 hereunder,
Sunstone may, at any time after the Initial Lock-Up Period, elect to file a
registration statement pursuant to Rule 415 under the Securities Act permitting
the resale of all Registrable Securities and shall covenant and agree to keep
such registration statement effective for a period of two years after the
expiration of the Initial Lock-Up Period (or such shorter period as to any
Holder that is then entitled to sell his or its Registrable Securities under
Rule 144 in any three-month period without restriction). All other provisions of
this Agreement shall continue to apply to any such registration. Upon expiration
of the initial two-year registration, if a Holder still holds Registrable
Securities that cannot be sold under Rule 144 during any three-month period
without restriction, Sunstone will file a new registration statement pursuant to
Rule 415 under the Securities Act (or maintain the effectiveness of the initial
registration statement) permitting the resale of all such Registrable Securities
that then remain unsold and shall keep such registration statement effective for
one additional period of two years.

            6.    Indemnification.

                  (a) Indemnification by Sunstone. In the event of any
registration of any securities of Sunstone under the Securities Act pursuant to
Section 2 or 3, Sunstone will, and it hereby does, indemnify and hold harmless,
to the extent permitted by law, the seller of any Registrable Securities covered
by such registration statement, each affiliate of such seller and their
respective directors and officers or general and limited partners or members or
managing members (including any director, officer, affiliate, employee, agent or
controlling Person of any of the foregoing), each other Person who participates
as an underwriter in the offering or sale of such securities and each other
Person, if any, who controls such seller or any such underwriter within the
meaning of the Securities Act (collectively, the "Seller Indemnified Parties"),
against any and all losses, claims, damages or liabilities, joint or several,
and expenses (including reasonable attorney's fees and reasonable expenses of
investigation) to which such Seller Indemnified Party may become subject under
the Securities Act, common law or otherwise, insofar as such losses, claims,
damages or liabilities (or actions or proceedings in respect thereof, whether or
not such Seller Indemnified Party is a party thereto) arise out of or are based
upon (i) any untrue statement or alleged untrue statement of any material fact



                                     -11-



                                Page 130 of 139

<PAGE>   12
contained in any registration statement under which such securities were
registered under the Securities Act, any preliminary, final or summary
prospectus contained therein, or any amendment or supplement thereto, or (ii)
any omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein (in the case of a
prospectus, in light of the circumstances under which they were made) not
misleading, and Sunstone will reimburse such Seller Indemnified Party for any
legal or any other expenses reasonably incurred by it in connection with
investigating or defending against any such loss, claim, liability, action or
proceeding (collectively, a "Violation"); provided that Sunstone shall not be
liable to any Seller Indemnified Party in any such case to the extent that any
such loss, claim, damage, liability (or action or proceeding in respect thereof)
or expense arises out of or is based upon any untrue statement or alleged untrue
statement or omission or alleged omission made in such registration statement or
amendment or supplement thereto or in any such preliminary, final or summary
prospectus in reliance upon and in conformity with written information furnished
to Sunstone through an instrument duly executed by such seller specifically
stating that it is for use in the preparation thereof nor shall it apply to
amounts paid in settlement of any such loss, claim, damage, liability, or action
if such settlement is effected without the consent of Sunstone (which consent
shall not be unreasonably withheld or delayed); and provided, further, that in
the case of any registration effected pursuant to Section 3 or any registration
effected pursuant to Section 2 in which the underwriters have agreed to
indemnify the Holders for the matters set forth in this proviso, if any losses,
claims, damages or liabilities arise out of or are based upon a Violation which
did not appear in the final prospectus, Sunstone shall not have any liability
with respect thereto to the Holder, any underwriter, or any person who controls
such Holder or underwriter within the meaning of Section 15 of the Securities
Act if the Holder or underwriter delivered a copy of the preliminary prospectus
to the person alleging such losses, claims, damages or liabilities and failed to
deliver a copy of the final prospectus, as so supplemented, to such person at or
prior to the written confirmation of the sale to such person. Such indemnity
shall remain in full force and effect regardless of any investigation made by or
on behalf of such seller or any Seller Indemnified Party and shall survive the
transfer of such securities by such seller.

                  (b) Indemnification by the Seller. In the event of any
registration of any securities of Sunstone under the Securities Act pursuant to
Section 2 or 3, each selling Holder will, and it hereby does, indemnify and hold
harmless, to the extent permitted by law, Sunstone and all other prospective
sellers of Registrable Securities, each affiliate of Sunstone or such seller and
their respective directors and officers or general and limited partners or
members or managing members (including any director, officer, affiliate,
employee, agent or controlling Person of any of the foregoing) and each other
Person, if any, who controls Sunstone or any such seller within the meaning of
the Securities Act (collectively, the "Company Indemnified Parties") against any
and all losses, claims, damages or liabilities, joint or several, and expenses
(including reasonable attorney's fees and reasonable expenses of investigation)
to which such Company Indemnified Party may become subject under the Securities
Act, common law or otherwise, insofar as such losses, claims, damages or
liabilities (or actions or proceedings in respect thereof, whether or not such
Company Indemnified Party is a party thereto) arise out of or are based upon any
untrue statement or alleged untrue statement in or omission or alleged omission
from such registration statement, any preliminary, final or summary prospectus



                                     -12-



                                Page 131 of 139
 
<PAGE>   13
contained therein, or any amendment or supplement, if such untrue statement or
alleged untrue statement or omission or alleged omission was made in reliance
upon and in conformity with written information furnished to Sunstone through an
instrument duly executed by such seller specifically stating that it is for use
in the preparation of such registration statement, preliminary, final or summary
prospectus or amendment or supplement, or a document incorporated by reference
into any of the foregoing, provided that no Holder shall be liable to any
Company Indemnified Party with respect to amounts paid in settlement of any such
loss, claim, damage, liability or action if such settlement is effected without
the consent of such Holder (which consent shall not be unreasonably withheld or
delayed); and provided further that if any losses, claims, damages or
liabilities arise out of or are based upon a violation which did not appear in
the final prospectus, no Holder shall have any liability with respect thereto to
Sunstone, any other seller or any person who controls Sunstone or such other
seller within the meaning of Section 15 of the Securities Act if Sunstone or an
underwriter delivered a copy of the preliminary prospectus to the person
alleging such losses, claims, damages or liabilities and failed to deliver a
copy of the final prospectus, as so supplemented, to such person at or prior to
the written confirmation of the sale to such person. Such indemnity shall remain
in full force and effect regardless of any investigation made by or on behalf of
Sunstone or any of the prospective sellers, or any of their respective
affiliates, directors, officers or controlling Persons and shall survive the
transfer of such securities by such seller. In no event shall the liability of
any selling Holder of Registrable Securities hereunder be greater in amount than
the dollar amount of the proceeds received by such Holder upon the sale of the
Registrable Securities giving rise to such indemnification obligation.

                  (c) Notices of Claims, Etc. Promptly after receipt by a Seller
Indemnified Party or a Company Indemnified Party (an "Indemnified Party")
hereunder of written notice of the commencement of any action or proceeding with
respect to which a claim for indemnification may be made pursuant to this
Section 6, such Indemnified Party will, if a claim in respect thereof is to be
made against an indemnifying party, give written notice to the latter of the
commencement of such action; provided that the failure of the Indemnified Party
to give notice as provided herein shall not relieve the indemnifying party of
its obligations under the preceding subdivisions of this Section 6, except to
the extent that the indemnifying party is actually prejudiced by such failure to
give notice. In case any such action is brought against an Indemnified Party,
unless in such Indemnified Party's reasonable judgment a conflict of interest
between such Indemnified Party and indemnifying parties may exist in respect of
such claim, the indemnifying party will be entitled to participate in and to
assume the defense thereof, jointly with any other indemnifying party similarly
notified to the extent that it may wish, with counsel reasonably satisfactory to
such Indemnified Party, and after notice from the indemnifying party to such
Indemnified Party of its election so to assume the defense thereof, the
indemnifying party will not be liable to such Indemnified Party for any legal or
other expenses subsequently incurred by the latter in connection with the
defense thereof other than reasonable costs of investigation. In the event that
the Indemnified Parties are conducting the defense of any action or other
claims, the indemnifying party will not be responsible for the costs and
expenses of more than one counsel for all of the Indemnified Parties (plus the
fees and expenses of one local counsel if the action is pending in a foreign
jurisdiction). No indemnifying party will consent to entry of any judgment or
enter into any settlement which does not include as an unconditional



                                     -13-



                                Page 132 of 139

<PAGE>   14
term thereof, the giving by the claimant or plaintiff to such Indemnified Party
of a release from all liability in respect to such claim or litigation.

                  (d) Contribution. If the indemnification provided for in this
Section 6 from the indemnifying party is unavailable to an Indemnified Party
hereunder in respect of any losses, claims, damages, liabilities or expenses
referred to herein, then the indemnifying party, in lieu of indemnifying such
Indemnified Party, shall contribute to the amount paid or payable by such
Indemnified Party as a result of such losses, claims, damages, liabilities or
expenses in such proportion as is appropriate to reflect the relative fault of
the indemnifying party and Indemnified 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 such
indemnifying party and Indemnified Parties 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 or omission or alleged omission to
state a material fact, has been made by, or relates to information supplied by,
such indemnifying party or Indemnified 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 under this Section 6(d) as a
result of the losses, claims, damages, liabilities and expenses referred to
above shall include any legal or other fees or expenses reasonably incurred by
such party in connection with any investigation or proceeding.

            The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 6(d) were determined by pro rata
allocation or by any other method of allocation which does not take into account
the equitable considerations referred to in the immediately preceding paragraph.
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 fraudulent misrepresentation.

                  (e) Other Indemnification. Indemnification similar to that
specified in the preceding subdivisions of this Section 6 (with appropriate
modifications) shall be given by Sunstone and each seller of Registrable
Securities with respect to any required registration or other qualification of
securities under any federal or state law or regulation or governmental
authority other than the Securities Act.

                  (f) Non-Exclusivity. The obligations of the parties under this
Section 6 shall be in addition to any liability which any party may otherwise
have to any other party.

                  (g) Conflicting Provisions. To the extent that the provisions
of this Section 6 differ from the terms and conditions of any indemnification
provision contained in any underwriting agreement entered into in connection
with any underwritten offering effected pursuant to Section 2 hereof, the
indemnification provisions contained in such underwriting agreement will, for
all purposes, supersede the terms and conditions of this Section 6. To the
extent that the provisions of this Section 6 differ from the terms and
conditions contained in any underwriting agreement entered into in connection
with any underwritten offering effected pursuant to Section 3 hereof, then (x)
unless otherwise agreed to by the Holders of Registrable



                                     -14-



                                Page 133 of 139

<PAGE>   15
Securities participating in any such registration, with respect to the
substantive scope and limitations (including, without limitation, the maximum
liability of the Holders) of the indemnification and contribution provided by
Sunstone and the Holders to the Indemnified Person, the provisions of this
Section 6 shall govern and supersede the terms of such Underwriting Agreement
and (y) with respect to all other matters the terms of the underwriting
agreement will supersede the terms and conditions of this Section 6.

                  (h) Indemnification by Underwriters. Sunstone may require, as
a condition to including any Registrable Securities in any registration
statement filed in accordance with Section 3 herein, that Sunstone shall have
received an undertaking reasonably satisfactory to it from any underwriter to
indemnify and hold harmless Sunstone in customary form.

            7. Rule 144. Sunstone covenants that it will file the reports
required to be filed by it under the Securities Act and the Exchange Act and the
rules and regulations adopted by the SEC thereunder (or, if Sunstone is not
required to file such reports, it will, upon the request of any Holder of
Registrable Securities, make publicly available such information), and it will
take such further action as any Holder of Registrable Securities may reasonably
request, all to the extent required from time to time to enable such Holder to
sell shares of Registrable Securities without registration under the Securities
Act within the limitation of the exemptions provided by (i) Rule 144 under the
Securities Act, as such Rule may be amended from time to time or (ii) any
similar rule or regulation hereafter adopted by the SEC. Upon the request of any
Holder of Registrable Securities, Sunstone will deliver to such Holder a written
statement as to whether it has complied with such requirements. Notwithstanding
anything contained in this Section 7, Sunstone may de-register under Section 12
of the Exchange Act if it is then permitted to do so pursuant to the Exchange
Act and the rules and regulations thereunder and, in such circumstances, shall
not be required hereby to file any reports which may be necessary in order for
Rule 144 or any similar rule or regulation to be available.

            8. Selection of Counsel. In connection with any registration of
Registrable securities pursuant to Sections 2 and 3 hereof, the Holders of a
majority of the Registrable Securities covered by any such registration may
select one counsel to represent all Holders of Registrable Securities covered by
such registration.

            9.    Miscellaneous.

                  (a) Amendments and Waivers. This Agreement may be amended and
Sunstone may take any action herein prohibited, or omit to perform any act
herein required to be performed by it, only if Sunstone shall have obtained the
written consent to such amendment, action or omission to act, of the Holders of
a majority of the Registrable Securities then outstanding; provided, however,
that no amendment, waiver or consent to the departure from the terms and
provisions of this Agreement that is adverse to the Funds or any of their
respective successors and assigns shall be effective as against any such Person
for so long as such Person holds any Registrable Securities unless consented to
in writing by such Person. Each Holder of any Registrable Securities at the time
or thereafter outstanding shall be bound by any consent



                                     -15-



                                Page 134 of 139

authorized by this Section 9(a), whether or not such Registrable Securities
shall have been marked to indicate such consent.

                  (b) Successors, Assigns and Transferees. This Agreement shall
be binding upon and shall inure to the benefit of the parties hereto and their
respective successors and assigns. The rights to cause the Company to register
Registrable Securities pursuant to Section 2 or 3 may be assigned (but only with
all related obligations) by a Holder to a transferee or assignee of such
securities, provided: (a) the Company is, within a reasonable time after such
transfer, furnished with written notice of the name and address of such
transferee or assignee and the securities with respect to which such
registration rights are being assigned; (b) such transferee or assignee assigns
in writing to be bound by and subject to the terms and conditions of this
Agreement. Without limitation of the foregoing, in the event that either of the
Funds distributes or otherwise transfers any shares of the Registrable
Securities to any of its present or future general or limited partners, Sunstone
hereby acknowledges that the registration rights granted pursuant to this
Agreement shall be transferred to such partner or partners on a pro rata basis,
and that at or after the time of any such distribution or transfer, any such
partner or group of partners shall designate a Person to act on its behalf in
delivering any notices or making any requests hereunder. Notwithstanding the
foregoing, in the event of a transfer of the registration rights granted
pursuant to this Agreement to a Fund's general or limited partners, such
partners shall not have any registration rights pursuant to Section 2 with
respect to any registration effected pursuant to Rule 415 under the Securities
Act.

                  (c) Notices. All notices and other communications provided for
hereunder shall be in writing and shall be sent by first class mail, telex,

participating in the offering, to the extent requested by the Company, sell or
otherwise transfer or dispose of (other than to donees who agree to be similarly
