ITEM 5. OTHER EVENTS

        On September 8, 1997, a Transaction Agreement (the "Transaction
Agreement") was entered into among Starwood Lodging Trust (the "Trust"), SLT
Realty Limited Partnership (the "Realty Partnership"), Starwood Lodging
Corporation (the "Corporation") and SLC Operating Limited Partnership (the
"Operating Partnership" and, together with the Trust, the Realty Partnership and
the Corporation, the "Starwood Companies"), WHWE L.L.C. ("WHWE"), Woodstar
Investor Partnership ("Woodstar"), Nomura Asset Capital Corporation ("Nomura"),
Juergen Bartels ("Bartels" and, together with WHWE, Woodstar and Nomura, the
"Members"), Westin Hotels & Resorts Worldwide, Inc. ("Westin Worldwide"), W&S
Lauderdale Corp. ("Lauderdale"), W&S Seattle Corp. ("Seattle"), Westin St. John
Hotel Company, Inc. ("St. John"), W&S Denver Corp. ("Denver"), W&S Atlanta Corp.
("Atlanta" and, together with Westin Worldwide, Lauderdale, Seattle, St. John
and Denver, "Westin") and W&S Hotel L.L.C. (the "LLC" and, together with Westin,
the "Westin Companies"). Westin owns, manages, franchises and represents 108
hotels and resorts, with approximately 47,800 rooms in 23 countries worldwide.

         The Transaction Agreement provides that Westin Worldwide will be merged
into the Trust (the "Merger"). In connection with the Merger, all of the issued
and outstanding shares of capital stock of Westin Worldwide (other than
dissenting shares and shares held by Westin and its subsidiaries or shares held
by the Starwood Companies and their subsidiaries) will be converted into an
aggregate of 6,285,783 Class A Exchangeable Preferred Shares, par value $.01 per
share (the "Class A EPS"), of the Trust and 5,294,783 Class B Exchangeable
Preferred Shares, liquidation value $38.50 per share (the "Class B EPS"), of the
Trust and cash in the amount of $177.926 million. The Transaction Agreement
provides for an adjustment to the cash consideration paid in connection with the
Merger under certain circumstances, including adjustments based on the aggregate
indebtedness and working capital of Westin on the closing date and the capital
expenditures made by Westin between the date the Transaction Agreement was
signed and the closing date. The Transaction Agreement also permits Westin
Worldwide to make a cash dividend in an amount up to $160 million to its
stockholders during 1997, which dividend Westin Worldwide had determined that it
expected to make prior to the execution of the Transaction Agreement and
irrespective of the closing under the Transaction Agreement.

         The Transaction Agreement also contemplates that the stockholders of
Lauderdale, Seattle and Denver will contribute all of the outstanding shares of
such companies to the Realty Partnership and that the Realty Partnership will
issue to such stockholders an aggregate of 597,844 units of the Realty
Partnership. In addition, in connection with the foregoing share contributions,
the Realty Partnership will assume, repay or refinance the indebtedness of
Lauderdale, Seattle and Denver and assume up to $147.2 million of indebtedness
incurred by the Members prior to such contributions. The Transaction Agreement
also permits Lauderdale and Seattle to make cash dividends in an aggregate
amount up to $6 million to their stockholders during 1997, which dividends
Lauderdale and Seattle had determined that they expected to make prior to the
execution of the Transaction Agreement and irrespective of the closing under the
Transaction Agreement. The Transaction Agreement also permits Denver to make a
cash dividend to its stockholders in an amount equal to Denver's earnings and
profits for 1997, which dividend Denver had determined that it expected to make
prior to the execution of the Transaction Agreement and irrespective of the
closing under the Transaction Agreement. In the event that Denver makes any such
cash dividend, the cash portion of the consideration to be paid in connection
with the Merger will be decreased by an amount equal to the amount of such
dividend.

         The Transaction Agreement also contemplates that the stockholders of
Atlanta and St. John will contribute all of the outstanding shares of such
companies to the Operating Partnership and that the Operating Partnership will
issue to such stockholders an aggregate of 393,156 units of the Operating
Partnership. In addition, prior to the foregoing share contributions, the
Operating Partnership will assume, repay or refinance indebtedness of Atlanta
and St. John and assume up to $6 million of indebtedness expected to be incurred
by the Members prior to such contributions. The Transaction Agreement also
contemplates that prior to the closing date, the Realty Partnership will lend
Atlanta approximately $34.2 million and permits Atlanta to pay a dividend of
such amount to its stockholders, which dividend Atlanta had determined that it
expected to make prior to the execution of the Transaction Agreement and
irrespective of the closing under the Transaction Agreement.

         The Class A EPS, Class B EPS and partnership units to be issued in
connection with the Merger and the contribution of Seattle, Lauderdale, Denver,
St. John and Atlanta to the Realty Partnership and the Operating Partnership
will provide the holders thereof with substantially the same economics as, and
will be exchangeable on a one-for-one basis (subject to certain adjustments)
for, the paired shares of the Trust and the Corporation. 

         In addition, the shares of Class B EPS and the partnership units to be
issued in the transactions contemplated by the Transaction Agreement will
provide a liquidation preference of $38.50 and provide the holders with a right
from and after the fifth anniversary of the Closing Date to require the Trust to
redeem such shares of Class B EPS and such partnership units at a price of
$38.50.

         The closing is subject to numerous conditions, including, among other
things, that the Transaction Agreement shall have been duly approved by holders
of the paired shares of the Trust and the Corporation, the waiting period under
the Hart-Scott-Rodino Antitrust Improvements Act shall have expired or been
terminated, an opinion shall have been delivered by counsel to the Starwood
Companies with respect to certain tax matters, there shall have been no change
in the general economic, financial or market conditions in the United States
that materially and adversely affects the ability of the Starwood Companies to
obtain the financing necessary to consummate the transactions contemplated by
the Transaction Agreement and the owners of hotels party to management,
franchise or similar agreements with the Westin Companies from whom consents,
approvals or authorizations are required to be obtained in connection with the
consummation of the transactions contemplated by the Transaction Agreement shall
not have delivered written notices of their intention to terminate agreements
that would account for $8 million or more of the projected revenues for 1998.

        The Transaction Agreement provides that if the Transaction Agreement is
terminated under certain circumstances, the Starwood Companies will be required
to pay the Westin Companies a termination fee of $5 million and all costs and
expenses incurred by the Westin Companies and the Members in connection with the
Transaction Agreement and the transactions contemplated thereby in an amount not
to exceed $5 million.

NOTE 1. BASIS OF PRESENTATION
 
     (A) The Trust and the Corporation have unilateral control of SLT Realty
Limited Partnership ("Realty") and SLC Operating Limited Partnership
("Operating" and together with Realty the "Partnerships"), respectively, and,
therefore, the historical financial statements of Realty and Operating are
consolidated with those of the Trust and the Corporation. Unless the context
otherwise requires, all references herein to the "Company" refer to the Trust
and the Corporation, and all references to the "Trust" and the "Corporation"
include the Trust and the Corporation and those entities respectively owned or
controlled by the Trust or the Corporation, including Realty and Operating,
respectively.
 
NOTE 2. WESTIN ACQUISITION
 
     (B) On September 9, 1997, the Company announced the execution of a
definitive agreement to acquire W&S Hotel L.L.C. (the "LLC" and, together with
its subsidiaries, "Westin") and its subsidiaries for approximately $1.829
billion. The subsidiaries of the LLC consist of: Westin Worldwide, Lauderdale,
Seattle, St. John, Denver and Atlanta. As part of the acquisition, Westin
Worldwide will be merged into the Trust, the stock of Seattle, Lauderdale and
Denver (which own the Westin Hotel Seattle, the Westin Hotel Fort Lauderdale and
the Westin Hotel Tabor Center, respectively) will be contributed to Realty and
the stock of Atlanta and St. John (which own the Westin Peachtree Plaza and the
Westin Resort, St. John, respectively) will be contributed to Operating. Also as
part of the acquisition, certain assets of Westin Worldwide, including portions
of its management and franchising operations, and of Seattle, Lauderdale and
Denver are expected either to be transferred to the Corporation and Operating or
transferred into subsidiaries in which the Trust will own nonvoting preferred
stock and less than 10% of the voting stock and the Corporation will own more
than 90% of the voting stock.
 
     The pro forma adjustments allocate Westin's assets between the Trust and
the Corporation in accordance with the terms of the acquisition. As a result,
all the properties owned by Westin (other than the Westin Peachtree Plaza and
the Westin Resort, St. John) are combined with the Trust and the remaining
assets of Westin are combined with the Corporation. The following is a list of
the hotels that are wholly-owned by Westin:

to issue 6,285,783 shares of newly created Class A Exchangeable Preferred Stock
with an aggregate value of approximately $310.8 million (using the closing stock
price of $49.4375 per paired share on September 8, 1997) and 5,294,783 shares of
newly created Class B Exchangeable Preferred Stock with an aggregate value of
approximately $261.8 million (using the closing stock price of $49.4375 per
paired share on September 8, 1997). The Company also intends to issue 991,000
limited partnership units of the Partnerships with an aggregate value of
approximately $49.0 million (using the closing stock price of $49.4375 per

     Finally, the Company intends to assume approximately $1.030 billion of debt
and pay cash in the amount of approximately $178.0 million to be drawn down
under the Company's revolving line of credit. The Company expects to refinance
some of Westin's debt to obtain credit terms similar to the Company's existing
credit facilities.

all references herein to the "Company" refer to the Trust and the Corporation,
and all references to the "Trust" and the "Corporation" include the Trust and
the Corporation and those entities respectively owned or controlled by the Trust
or the Corporation, including Realty and Operating.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Members of
W&S Hotel L.L.C.:
 
     We have audited the accompanying consolidated balance sheets of W&S Hotel
L.L.C. (a Delaware limited liability company) and subsidiaries as of December
31, 1996 and 1995, and the related consolidated statements of operations,
members' equity and cash flows for the year ended December 31, 1996 and for the
period from acquisition (May 12, 1995) through December 31, 1995. We have also
audited the accompanying combined statements of operations, changes in net
assets and cash flows of the predecessor business (as defined in Note 1) for the
year ended December 31, 1994, and for the period from January 1, 1995 through
May 12, 1995. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of W&S Hotel
L.L.C. and subsidiaries as of December 31, 1996 and 1995, and the consolidated
results of their operations and their cash flows for the year ended December 31,
1996 and for the period from acquisition (May 12, 1995) through December 31,
1995, and the combined results of operations, changes in net assets and cash
flows of the predecessor business for the year ended December 31, 1994, and for
the period from January 1, 1995 through May 12, 1995, in conformity with
generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
                           DECEMBER 31, 1996 AND 1995
 
1. BASIS OF PRESENTATION
 
     W&S Hotel L.L.C. (the LLC) acquired the stock of Westin Hotel Company and
certain additional subsidiaries and affiliates on May 12, 1995 (the
acquisition). Prior to the acquisition, the LLC had no material operations. The
consolidated financial statements of the LLC include the results of operations
of the acquired enterprises since the acquisition. The combined financial
statements of the predecessor business include the results of operations of the
acquired enterprises prior to the purchase but exclude businesses and assets not
acquired. The LLC and the predecessor business are collectively referred to in
these notes as the Company.
 
     The accompanying interim consolidated financial statements of the LLC have
been prepared by the LLC without audit. Certain information and footnote
disclosures normally included in financial statements presented in accordance
with generally accepted accounting principles have been condensed or omitted.
All amounts and disclosures included in the notes for the six months ended June
30, 1997 and 1996, and as of June 30, 1997 are unaudited. Management of the LLC
believes the disclosures made are adequate to make the information presented not
misleading. However, the interim consolidated financial statements should be
read in conjunction with the consolidated financial statements and notes
thereto.
 
     In the opinion of management of the LLC, the accompanying interim unaudited
consolidated financial statements reflect all adjustments (which include only
normal recurring adjustments) necessary to present fairly the financial position
of the LLC as of June 30, 1997 and the results of operations and cash flows for
the six months ended June 30, 1997 and 1996. Interim results are not necessarily
indicative of fiscal year performance because of the impact of seasonal and
short-term variations.
 
2. DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     A. DESCRIPTION OF BUSINESS
 
     The Company operates in the lodging industry under the name of Westin
Hotels & Resorts. It owns, manages, franchises and represents upscale hotels and
resorts in locations worldwide. Substantially all owned hotels and partnerships
are located in the United States. Operating revenues from hotel operations
consist of rooms, food and beverage and other operating department revenues
generated by owned hotels. Operating revenues from management services are
primarily for management, franchise and related services provided to nonowned
hotels.
 
     The Company also provides workers' compensation, property, general and
automobile liability coverage to the owned and managed hotels through its wholly
owned subsidiary, Westel Insurance Company.
 
     B. MEMBERS' EQUITY
 
     The LLC is a limited liability company formed on November 21, 1994, under
the laws of Delaware. It shall continue until December 31, 2044, unless
terminated sooner.
 
     There are Class A members and a Class B member in the LLC. The Class A
members are Woodstar Investor Partnership, an affiliate of the Starwood Capital
Group L.P.; WHWE L.L.C., an affiliate of Goldman, Sachs & Co.; and a senior
executive of the Company. Nomura Asset Capital Corporation is the sole Class B
member. Members' liability is limited to their respective capital contributions.
Concurrence of the Class B member is required for certain decisions.
 
     Earnings and losses of the LLC after a preferred return are generally
allocated to each member in accordance with their respective percentage
interests, but losses are allocated first to members with positive equity
balances. The percentage interests totaled 73% for Class A members and 27% for
the Class B member. Generally, distributions of net proceeds from operations and
excess refinancing proceeds are made to the
 
                                      F-29
<PAGE>   34
 
Class A members to the extent of interest on their unreturned capital
contributions, and thereafter, to all members in proportion to their respective
percentage interests.
 
     The original Class A members have committed to contribute capital up to
$132,000,000 no later than May 12, 1998. As of December 31, 1996, these members
had contributed cash of $93,000,000 and notes of $2,640,000. In lieu of
receiving distributions, the Class A members have reduced their remaining
capital commitment by approximately $18,000,000 through December 31, 1996. There
are significant restrictions on the ability to transfer the Class A members'
interests. The remaining capital commitment and additional contributions were
funded during the six months ended June 30, 1997 in connection with hotel
acquisitions.
 
     C. CONSOLIDATION
 
     The consolidated and combined financial statements include the accounts of
the Company and the acquired subsidiaries. The consolidated and combined
statements of operations also include the Company's share of net income from
partnerships. All significant intercompany transactions and accounts have been
eliminated.
 
     D. ACCOUNTING ESTIMATES
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities, the
disclosure of contingent assets and liabilities at the date of the financial
statements, and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
     E. CASH AND CASH EQUIVALENTS
 
     Cash and cash equivalents consist of cash and highly liquid debt
instruments bearing floating interest rates and other short-term investments
purchased with a maturity of three months or less.
 
     F. GUEST AND TRADE RECEIVABLES
 
     In the ordinary course of business, the Company extends credit to guests of
owned hotels, primarily business travelers. In addition, the Company extends
credit to managed and franchised hotels located principally in North America and
Asia for the payment of management and marketing fees and for reimbursement of
payroll and other expenses.
 
     G. INVENTORIES
 
     Inventories include food, beverage and supplies and are valued at the lower
of cost (first-in, first-out) or replacement market.
 
     H. INVESTMENTS IN PARTNERSHIPS
 
     The Company's investments in partnerships that are not majority-owned or
controlled are accounted for using the equity method.
 
     I. PROPERTY AND EQUIPMENT
 
     Depreciation and amortization of property and equipment are provided using
the straight-line method over the assets' estimated useful lives as follows:
 
<TABLE>
<S>                                   <C>
Buildings and leasehold
  improvements......................  Shorter of 5-45 years or remaining lease
                                      term
Furniture, fixtures and equipment...  2-12 years
Expendable supplies.................  2-4 years
</TABLE>
 
     The Company uses an annual group method of depreciation. Under this method,
individual assets are not specifically identified for purposes of determining
retirements. Fully depreciated asset groups are written off the year after they
are fully depreciated. Proceeds from miscellaneous sales of depreciable property
and equipment are credited to accumulated depreciation.
 
                                      F-30
<PAGE>   35
 
     Expendable supplies include linens, china, silverware and glassware. They
are depreciated to 50% of the cost of initial stock. Replacements are expensed
when purchased.
 
     Maintenance and repairs, including the cost of minor replacements, are
charged to property maintenance expense accounts. The cost of additions and
betterments of property are capitalized to property and equipment accounts.
 
     Interest incurred during the construction or renovation of hotels and
related facilities is capitalized and amortized over the estimated useful lives
of the assets. No interest was capitalized in 1996, 1995 or 1994. In the six
months ended June 30, 1997, capitalized interest totaled $411,000.
 
     J. INTANGIBLE AND OTHER ASSETS
 
     Intangible and other assets include management contracts, goodwill,
software and deferred loan costs. Management contracts represent the allocation
of the Company's acquisition cost based on the estimated present value of income
primarily from management agreements, less accumulated amortization. The direct
costs incurred to obtain a management or franchise agreement are also
capitalized. Goodwill represents the excess of the Company's acquisition cost
over the net fair value of assets acquired and liabilities assumed, less
accumulated amortization. Deferred loan costs and computer software are stated
at cost, less accumulated amortization. Capitalized cost for computer software
includes both external and internal labor costs directly attributable to the
development of software.
 
     The costs incurred to acquire management contracts are amortized using the
straight-line method over the lives of the contracts. Goodwill is amortized
using the straight-line method. Deferred loan costs are amortized using the
straight-line method, which approximates the effective interest method over the
contractual terms of the related indebtedness. Software costs are amortized
using the straight-line method over the estimated economic lives of the
software, not to exceed seven years. Estimated useful lives are as follows:
 
<TABLE>

                                               W&S HOTEL L.L.C.   PREDECESSOR BUSINESS
                                               ----------------   --------------------
<S>                                            <C>                <C>
Management contracts.........................     5-15 years            25 years
Goodwill.....................................       40 years            40 years
Deferred loan costs..........................      2-7 years                 N/A
Software.....................................      2-7 years             7 years
</TABLE>
 
     The estimated lives of the management contracts include the weighted
averages of the remaining contract periods as of the respective business
acquisition dates. The predecessor owner acquisition occurred in 1988.
 
     Management periodically assesses the carrying value of intangible assets to
determine whether any changes in estimated useful lives have occurred.
 
     K. LONG-LIVED ASSETS
 
     The recoverability of management contract costs, goodwill and hotel
investments are periodically evaluated to determine whether such costs will be
recovered from future operations. Evaluations of goodwill are based on estimated
undiscounted cashflow. Management contracts and hotel investments are
individually evaluated based on undiscounted cashflow. If the undiscounted
amounts are insufficient to recover the recorded assets, then the estimated
amounts are discounted to determine the revised carrying value and a write-down
for the difference is recorded.
 
     L. DERIVATIVE FINANCIAL INSTRUMENTS
 
     The company enters into interest-rate protection agreements to manage
well-defined interest rate risk and does not use them for trading or speculative
purposes. The Company's agreements are with major international financial
institutions that are expected to fully perform under the terms of the
agreements thereby reducing the credit risk from the transactions.
 
                                      F-31
<PAGE>   36
 
     Fees paid for interest-rate protection agreements are recorded ratably as
interest expense over the terms of the agreements and the related impact on the
Company's cash flows is included in cash flows from operating activities.
 
     Gains or losses on interest-rate protection agreements that the Company
considers hedges, including hedges of anticipated refinancing transactions, are
deferred. In order for gains or losses for anticipated refinancing transactions
to be deferred the Company must determine, by reviewing its ability and intent
to refinance, that it is probable that the anticipated refinancing will occur.
If the Company concludes that an interest rate protection agreement no longer
qualifies as a hedge, gains or losses would be recorded as other income
(expense) at each reporting date based on the amount that would have been paid
or received to settle the agreement on the reporting date.
 
     M. INCOME TAXES
 
     The members of the LLC are required to include their respective share of
profits and losses in their separate income tax returns. Income taxes reflected
in the financial statements relate to taxable corporations owned by the LLC
included in the consolidated financial statements.
 
     The operations of the predecessor business have been included in the
consolidated tax returns of the predecessor owner and its affiliates. Income
taxes for the predecessor business have been computed assuming the Company was a
stand-alone entity.
 
     Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases, and to operating loss and tax credit carryforwards. Deferred tax assets
and liabilities are measured using enacted tax rates expected to apply to
taxable income in the years in which those temporary differences are expected to
be recovered or settled. The effect on the deferred tax assets and liabilities
of a change in tax rates is recognized in income in the period that includes the
enactment date.
 
     N. FOREIGN CURRENCY TRANSLATION
 
     The financial statements include foreign currency amounts attributed to
foreign subsidiaries and branches that have been translated into U.S. dollars
using year-end exchange rates for assets and liabilities and average annual
rates for revenues and expenses. Translation gains or losses arising from
fluctuations in the year-end exchange rates are recorded as equity adjustments
from foreign currency translations. Foreign exchange gains or losses recorded in
the statements of operations include actual foreign exchange transactions and
the effect of exchange rate fluctuations on assets or liabilities that are
denominated in currencies other than their own.
 
     O. ADVERTISING COSTS
 
     The Company expenses the production costs of advertising the first time the
advertising takes place.
 
     P. EQUITY-BASED COMPENSATION
 
     The Company accounts for its equity-based compensation following the fair
value accounting provisions of Statement of Financial Accounting Standards
(SFAS) No. 123, Accounting for Stock-Based Compensation. The predecessor
business did not have equity-based compensation arrangements.
 
3. BUSINESS ACQUISITION
 
     On May 12, 1995, the LLC acquired all of the stock of Westin Hotel Company
and certain additional investments, which are collectively referred to as the
predecessor business. The acquisition has been accounted for using the purchase
method of accounting. Accordingly, the total cost has been allocated to the
assets purchased and the liabilities assumed based upon the fair values at the
date of acquisition. The purchase price in excess of the estimated fair value of
the net assets acquired was $154,079,000 and has been recorded as goodwill.
Valuation allowances for deferred tax assets resulting principally from net
operating losses and foreign tax credit carryforwards were recorded as part of
the acquisition. If those net operating losses or foreign
 
                                      F-32
<PAGE>   37
 
tax credits are used, goodwill will be reduced accordingly. A summary of the
acquisition of the predecessor business follows:

</TABLE>
 
4. CASH MANAGEMENT
 
     The Company invests cash in excess of operating needs in short-term
investments in which its funds are available upon request. Under the program,
participants' cash receipts are deposited in a centralized bank account. The
full amount of the funds in the centralized account is available for use by the
participants in their normal operations. Interest income or expense is allocated
to participants that are not wholly owned based upon their net funds deposited
or borrowed under the program. The interest rate is based upon the average yield
of investments in the centralized account.
 
     At December 31, 1996 and 1995, the payable to affiliates includes
$3,010,000 and $2,503,000, respectively, representing net cash transfers under
the hotel cash management program.

     The LLC had a 50% ownership interest in Biltmore Hotel Partners, which
owned the Arizona Biltmore located in Phoenix, Arizona. Additionally, the LLC
received a preferred return on invested capital of $22,000,000. This amount,
which had previously been included in investments in partnerships, was repaid to
the LLC during the year ended December 31, 1996. In February 1997, the LLC sold
its interest in Biltmore Hotel Partners for $50,518,000. This transaction
generated a pretax gain of approximately $20,969,000, and net proceeds after a
required repayment of long-term debt were approximately $44,000,000. The net
proceeds from this transaction have been utilized to fund a portion of the
Company's hotel acquisitions.
 
     The Company has an approximate 49% ownership interest in the Westin O'Hare
Hotel Venture located at the O'Hare Airport in Chicago, Illinois, a 20%

     Additionally, a subsidiary of the Company is the general partner and has an
effective ownership interest of approximately 8% in Westin Hotels Limited
Partnership (WHLP), which owns The Westin Michigan Avenue in Chicago and The
Westin St. Francis in San Francisco, but has reduced the investment basis and
share of earnings to zero because of priorities associated with other investor
returns. At December 31, 1996, WHLP had assets of $263,148,000 and equity of
$68,381,000. At December 31, 1995, WHLP had assets of $246,698,000 and equity of
$61,403,000. WHLP had revenues of $110,950,000, $51,791,000, $45,453,000 and
$99,388,000 and net income (loss) of $6,978,000, $4,244,000, ($2,531,000) and

through December 31, 1995, the period from January 1, 1995 through May 12, 1995
and the year ended December 31, 1994, respectively.
 
     Investments include unamortized cost in excess of the Company's share of
the net assets of partnerships of $22,818,000 at December 31, 1996 ($19,700,000
is attributable to the investment in Biltmore Hotel Partners) and $32,230,000 at
December 31, 1995. This amount is being amortized into income over the lives of
the underlying assets.
 
     Partnership distributions totaled $25,378,000 in 1996 (including
$22,000,000 from the Biltmore Hotel Partners); $3,369,000 from May 12, 1995
through December 31, 1995; none from January 1, 1995 through May 12, 1995; and
$389,000 in 1994.
 
     During 1994, two investments in hotel companies located in Singapore, which
were less than 20% owned, were sold for gross proceeds of $28,363,000, resulting
in a gain of $16,404,000, net of a sales commission of $3,091,000 paid to an
associated company.

     Substantially all property and equipment is pledged as security under the
long-term debt agreements.
 
     There are restrictive covenants under the Subordinated Notes and under the
Senior Secured Notes which were repaid in 1997 as discussed below. These
covenants include maintaining specified levels of debt service coverage and
earnings before interest, taxes, depreciation and amortization and permit
dividends or capital distributions to be made to or by the LLC only if the
Company has complied with the terms of the long-term debt agreements.
 
     In May 1997, the Company elected not to exercise its option to extend the
due date of the Senior Secured Notes and repaid the notes with the proceeds of a
$331,000,000 Senior Credit Facility led by Goldman Sachs Credit Partners L.P..
This facility is comprised of a revolving facility of $50,152,000, and a term
facility of $280,848,000. The revolving facility matures in February 2002 and
the term facility matures in May 2002 and contains similar security and
restrictive covenants as the former Senior Secured Notes. The Senior Credit
Facility also contains restrictive covenants that require minimum levels of net
worth and certain leverage and interest coverage ratios.
 
     The loans incurred in 1997 are secured by the acquired hotel property and
equipment. The loan agreements typically require the hotel to fund reserves for
taxes, insurance, and debt service (current restricted cash) and for capital
replacement (noncurrent restricted assets). The acquired resort located in the
U.S. Virgin Islands has a total loan facility of $29,500,000. The resort will
borrow the remaining $9,500,000 in connection with a renovation.

     During 1995, in connection with its borrowing under the Senior Secured
Notes, the Company entered into an interest-rate protection agreement with the
lender, which is the sole class B member of the LLC. On the basis of interest
rates as of December 31, 1996, the settlement amount due to the lender would
have been approximately $5,449,000 had the Company repaid the outstanding
principal of the Senior Secured Notes on December 31, 1996.
 
     The Company accounted for the interest-rate protection agreement as a hedge
against its anticipated future refinancing debt risk. Accordingly, the Company
deferred recognition of changes in the estimated settlement amount of the
agreement. In connection with the repayment of the Senior Secured Notes, the
Company settled the interest rate protection agreement associated with the
Senior Secured Notes for an insignificant amount.
 
     The interest rate protection agreement also required that the Company pay
an interest-rate management fee equal to an annual rate of .93 percent of the
Senior Secured Note amount. This fee, which was approximately $3,098,000 in 1996
and $2,002,000 from May 12, 1995 to December 31, 1995, is included in interest
expense.
 
     The predecessor owner borrowed funds when it acquired the predecessor
business. The related interest cost has not been included in the predecessor
business financial statements as that debt has not been assumed by the LLC and
there are no ongoing guarantees or pledges of the Company's assets relating to
that debt.

     At December 31, 1996, the LLC's taxable subsidiaries had net operating
losses available for carryforward to future years of $10,722,000 for federal
income tax purposes that will expire in the years 2005 through 2010. The LLC's
taxable subsidiaries also had net operating losses available for carryforward to
future years relating to various city and state tax jurisdictions that aggregate
$63,824,000 and expire in the years 1997 through 2011.

     The foreign tax credits available for carryforward to future years of
$16,965,000 will expire in the years 1999 through 2001. Foreign tax credits
totaling $2,886,000 expired during 1996, and $860,000 of 1996 foreign tax
credits have been carried forward.
 
     The Company's alternative minimum tax credit carryforwards of $2,443,000
may be used indefinitely to reduce future regular federal income taxes to the
extent regular federal income taxes exceed alternative minimum tax. The general
business credits available for carryforward to future years of $855,000 will
expire in the years 2002 through 2011.
 
     Substantially all of the Company's valuation allowance is for net operating
loss and tax credit carryforwards generated through May 12, 1995. Future tax
benefits from these net operating loss and tax credit carryforwards for which a
valuation allowance has been provided will reduce goodwill. During 1996 goodwill
was reduced by $472,000 for tax benefits from operating loss carryforwards.
 
     The Company's valuation allowance decreased by a net $2,869,000 during
1996. This decrease was principally due to the expiration of tax credits and net
operating loss carryforwards for which a valuation allowance had previously been
provided.
 
     The Company's valuation allowance increased by $125,000 from May 12, 1995
through December 31, 1995, decreased by $769,000 from January 1, 1995 through
May 12, 1995 and increased by $2,253,000 during 1994. The changes in the
valuation allowance were primarily due to the net generation or utilization of
federal and state operating losses during the respective periods.
 
     The LLC is indemnified by the predecessor owner, subject to $2,000,000 to
be paid by the LLC after an agreed amount of current taxes are paid, against
taxes for periods prior to the acquisition. The LLC has recorded the $2,000,000
obligation in deferred income tax liabilities.

     Under a captive insurance program, the Company provides insurance coverage
for workers' compensation, automobile and general liability claims arising at
hotel properties owned or managed by the Company through policies written
directly and through assumed reinsurance arrangements. Estimated insurance
claims payable represent outstanding claims and those estimated to have been
incurred but not reported based upon historical loss experience. Actual costs
may vary from estimates based on trends of losses for filed claims and claims
estimated to be incurred but not yet filed.

     At December 31, 1996, standby letters of credit amounting to $23,000,000
had been issued to provide collateral for the estimated claims. The letters of
credit are guaranteed by the predecessor owner.
 
     Underwriting profit with respect to the captive insurance program amounted
to $3,250,000 and $3,333,000 for the six months ended June 30, 1997 and 1996,
respectively, $7,335,000 in 1996; $4,330,000 from May 12, 1995 through December
31, 1995; $2,381,000 from January 1, 1995 through May 12, 1995; and $3,607,000
in 1994. Amounts related to premium income are included in other departmental

expenses.
 
16.  PENSIONS
 
     The Company sponsors two domestic defined benefit plans and several defined
contribution plans. The Company has determined that it will primarily use
defined contribution plans to provide retirement benefits to employees.
 
     In December 1995, the Company amended its qualified noncontributory defined
benefit plan for management employees (Management Retirement Plan) to curtail
any further benefit accruals beyond December 31, 1995. All benefits earned under
the plan were vested at December 31, 1995. The plan has not been terminated. The
Company recognized a curtailment gain of $4,186,000 in accordance with SFAS No.
88, Employers' Accounting for Settlements and Curtailments of Defined Benefit
Pension Plans and for Terminated Benefits, in the May 12, 1995 through December
31, 1995 consolidated statement of operations.
 
     A noncontributory, nonqualified Supplemental Executive Retirement Plan
provides benefits for certain executives. The plan is unfunded apart from
general assets of the Company.
 
     The Company also sponsors a qualified investment and profit-sharing plan
covering domestic employees that meet certain minimum service requirements.
Participants are able to contribute a portion of their compensation to the plan.
The Company matches participant contributions up to a certain portion of
participant base pay. The Company also makes profit-sharing contributions to the
plan based on a portion of participants' base pay. The amount of expense for
investment matching and profit sharing totaled $1,300,000 in 1996; $1,157,000
from May 12, 1995 through December 31, 1995; $659,000 from January 1, 1995
through May 12, 1995; and $1,652,000 in 1994.
 
     The Company sponsors nonqualified deferred compensation plans for
executives. The Company makes matching contributions based on participant
contributions and percentages of compensation. One of the executive deferred
compensation plans also provides a fixed rate of return to participants. The
costs of the executive deferred compensation plans are not significant.

     The actuarial present value of the projected benefit obligation of the
Supplemental Executive Retirement Plan was determined assuming an increase in
future compensation levels of 6.0% and 6.5% at December 31, 1996 and 1995,
respectively. Because benefits were frozen on December 31, 1995, no assumption
for increases in future compensation levels was required in order to determine
the present value of the projected benefit obligation of the Management
Retirement Plan. An expected long-term rate of return on plan assets of 8.5% was
used in each period. A discount rate of 7.5% was used during 1994 and was
increased to 8.5% on December 31, 1994. It was subsequently reduced to 7.5% on
December 31, 1995, and remains unchanged on December 31, 1996. The changes in
the discount rate and future compensation levels have not had a significant
impact on net pension costs.
 
17. OTHER POSTRETIREMENT BENEFITS
 
     The Company sponsors two defined benefit postretirement plans that cover
certain domestic salaried employees. One plan provides life insurance, and the
other provides medical and dental benefits. The noncontributory life insurance
plan is fully funded and the related assets are invested in short-term U.S.
government securities. The postretirement health care plan is contributory, with
retiree contributions adjusted annually, and contains other cost-sharing
features such as deductibles and coinsurance. The Company funds the health plan
on a pay-as-you-go basis.

     For measurement purposes, a 7.0% annual rate of increase in the per capita
cost of covered health care benefits was assumed for 1996; the rate was assumed
to decrease gradually to 5% by 2016 and remain at that level thereafter. The
health care cost trend rate assumption has a significant effect on the amounts
reported. To illustrate, increasing the assumed health care cost trend rates by
one percentage point in each year would increase the accumulated postretirement
benefit obligation as of December 31, 1996 by $709,000 and the aggregate of the
service and interest cost components of net periodic postretirement benefit cost
for the year then ended by $129,000.
 
     An expected long-term rate of return on plan assets of 5% was used in 1996.
An expected long-term rate of return on plan assets of 5.7% was used in each of
the other periods. A discount rate of 7.5% was used during 1994 and was
increased to 8.5% on December 31, 1994. It was subsequently reduced to 7.5% on
December 31, 1995, and remains unchanged on December 31, 1996. The changes in
the discount rate have not had a significant impact on postretirement benefit
costs.

18. FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The carrying values of the Company's financial instruments approximate fair
value as determined by the Company, using appropriate market information and
valuation methodologies, as noted below. Considerable judgment is required to
develop the estimates of fair value. Thus, the estimates provided below as of
December 31 are not necessarily indicative of the amounts that could be realized
in a current market exchange.

19. COMMITMENTS AND CONTINGENCIES
 
     As of June 30, 1997, the Company had capital commitments as follows:
 
<TABLE>
<S>                                                           <C>

     Total commitments......................................  $32,178,000
                                                              ===========
</TABLE>
 
     Approximately $12,725,000 of capital expenditures will be funded from
mortgage loans and capital leases.
 
     The Company has also guaranteed its proportionate share of a joint venture
indebtedness totaling $2,800,000 and has provided operating cash flow guarantees
to a partnership and a managed hotel totaling $7,500,000.
 
     In January 1996 the Company, its Chief Executive Officer and a consultant
of the Company were named defendants in a lawsuit filed by Radisson Hotels
International, Inc. (Radisson). Radisson has asserted claims for patent
infringement, trade secret misappropriation, unfair competition and breach of
contract. The Company has filed motions for summary judgment seeking to
invalidate the patent and dismiss the other claims. The Company has indemnified
its consultant for Radisson's patent infringement claim. The plaintiff claims
substantial damages, but the Company believes that the alleged damages are
unsupported, the patent is invalid, and the case is without merit. The Company
intends to vigorously defend itself in these matters.
 
     The Company is also a defendant in various lawsuits which are incidental to
its business. Management believes that the ultimate resolution of these matters
will not have a material effect on the Company's financial position or results
of operations.
 
     The Company operates in Asia subject to an exclusive license granted by the
predecessor owner to manage, franchise and invest in hotels in Asia under the
Westin Hotels & Resorts name. The license has an initial term of ten years
commencing from May 12, 1995, with additional renewal provisions of up to 30
years at the Company's option provided certain conditions are met. Commencing in
May 1999, the Company has an option to acquire the rights, title and interest in
this license agreement for $90,000,000 plus certain adjustments. The purchase
option requires a cash payment of $60,000,000 plus a $30,000,000 20-year
promissory note. The exercise of this purchase option can be accelerated by the
predecessor owner if the Company acquires a controlling interest in a hotel
management company in the Asia territory.
 
20. MANAGEMENT AND SERVICE AGREEMENTS
 
     The Company provides management and related services to owned and nonowned
hotels under agreements with terms generally ranging from 2 to 30 years. Fees
paid to the Company are based primarily upon percentages of the hotels' gross
operating revenues or gross operating profits as defined in the agreements.

     The Company also maintains a corporate sales and marketing program. The
hotels reimburse the Company pro rata for marketing services, including all
costs in connection with hotel reservations. A financial summary of marketing
activities follows:

</TABLE>
 
     The net cost reflects the Company's pro rata share of sales, marketing and
hotel reservation costs.
 
     Additionally, under the agreements, the Company generally provides hotels
with the services of certain full-time employees. The Company is reimbursed for
these employees' salaries and related benefits.
 
     Management and representation fees to partnerships carried on the equity
basis of accounting are at terms that are comparable to fees under similar
agreements with unrelated third parties.
 
21. OPERATING LEASE OBLIGATIONS
 
     Operating lease agreements cover land, hotel buildings, office space,
furniture and equipment at several locations. Lease terms generally provide that
the Company is to pay minimum rentals, taxes, insurance, maintenance and
utilities associated with the leased properties, as well as rentals based upon
percentages of operating profits or revenues. Rent expense pursuant to
percentages of operating profits totaled $3,215,000 and $1,618,000 for the six
months ended June 30, 1997 and 1996, respectively. Additionally, percentage rent
expense totaled $3,633,000 for the year ended 1996 and was not material for 1995
or 1994.
 
     Future minimum lease payments are as follows:

</TABLE>
 
     A portion of the minimum lease payments are recovered as part of the
marketing services reimbursement.
 
22. EQUITY-BASED COMPENSATION
 
     During the period from May 12, 1995 to December 31, 1995, the LLC awarded
equity-based compensation to certain key employees. The equity-based
compensation arrangements consist of options granted to acquire up to 5% of the
outstanding equity of the LLC or its subsidiaries. The options vest over a
five-year period and may be exercised upon the earlier of five years or a change
in control in or liquidation of the LLC. The option strike prices increase from
initial strike prices based on the fair value of the LLC at the date of
employment, at annual rates ranging from 15% to 25%, with a weighted average
rate of increase of 18%. Additional options were granted during 1996
representing approximately .25% of the total outstanding
 
                                      F-49
<PAGE>   54
 
equity of the LLC or its subsidiaries. These options may be exercised based on
the estimated fair value of the LLC or its subsidiaries at the grant date,
increasing annually by 10% with similar vesting provisions as the options
granted in 1995. All options granted were outstanding at December 31, 1996.
Twenty percent of the options granted prior to December 31, 1995 were vested at
December 31, 1996. No options were exercisable and no options were exercised,
forfeited or expired during the period from May 12, 1995 to December 31, 1996.
 
     The LLC estimates the fair value of its stock options following the
provisions of SFAS 123, Accounting for Stock-Based Compensation. Under the
provisions of SFAS 123, the fair value of the LLC's increasing strike price
options is calculated based on the difference between a risk-free interest rate
that corresponds to the option period and the rate of increase of the option
strike price. Since the rates of increase exceed the risk-free interest rates of
5.4% at December 31, 1995 and 6.2% at December 31, 1996, the fair value of the
options at the time of the award was zero. Accordingly, no compensation expense
has been reflected in the accompanying financial statements. At December 31,
1996, the Company believes the market value of the LLC's equity subject to
option exceeds the corresponding option exercise price.

24. SUBSEQUENT EVENTS (UNAUDITED)
 
     In August 1997, the Company terminated its postretirement life insurance
plan. The insurance obligations were settled through the purchase of
nonparticipating single premium insurance contracts, and the remaining plan
assets totaling approximately $6,500,000 were transferred to a voluntary
employee benefit association (VEBA) to fund future medical expenses.
Additionally, the Company amended its postretirement medical plan to exclude a
substantial portion of its employees. A limited number of qualified employees
and
 
                                      F-50
<PAGE>   55
 
retirees will continue to receive this benefit. The Company estimates that the
impact of these benefit plan changes will result in a pretax gain of
approximately $2,400,000.
 
     Additionally, the Company has approved the termination of the management
retirement plan. The Company plans to settle the accumulated obligations through
nonparticipating insurance contracts. The Company anticipates that this
settlement, which is subject to regulatory approval, will result in a pre-tax
loss of approximately $4,000,000. This transaction is expected to be completed
in 1998.
 
     Subsequent to June 30, 1997, the Company entered into an interest-rate
protection agreement for a notional amount of $112,500,000 related to the Senior
Credit Facility. This agreement, which terminates in June 2000, provides for
interest rate protection in the event that floating interest rates exceed
certain levels.
 
     Subsequent to June 30, 1997 and pursuant to a private placement, the
Company offered shares in certain affiliates of Westin Hotel Company to certain
officers of the Company. The Company has received approximately $2,000,000 of
refundable deposits for these shares, but the subscriptions for such shares have
yet to be accepted by such affiliates of Westin Hotel Company. The offering may
be cancelled or postponed by the Company at any time before completion; in the
event the offering is cancelled or postponed, the purchase price deposits that
have been received by such affiliates of Westin Hotel Company in respect of such
offering would be refunded.
 
     In September 1997, the boards of managers and directors of the members of
the LLC entered into a transaction agreement to sell the stock of Westin Hotel
Company and its affiliates that are currently owned by the LLC. This sale, which
is scheduled to be completed in January 1998, includes substantially all assets,
liabilities and operations that are presently owned by the LLC.

parties ("Affiliated Shares") or Worldwide Shares ("Dissenting Shares" and,
together with the Affiliated Shares, the "Excluded Shares") that are owned by
stockholders ("Dissenting Stockholders") exercising appraisal rights pursuant to
Section 262 of the DGCL) shall be converted into, and become exchangeable for, a
pro rata portion (based upon the aggregate number of Worldwide Shares issued and
outstanding immediately prior to the Effective Time) of (x) a number of shares
of Class A Exchangeable Preferred Stock of Starwood Trust, par value $.01 per
share, having the terms set forth on Annex A hereto ("Class A EPS") equal to the
product of (A) the Nondissenting Portion times (B) 6,285,783, (y) a number of
shares of Class B Exchangeable Preferred Stock of Starwood Trust, liquidation
value $38.50 per share, having the terms set forth on Annex B hereto ("Class B
EPS") equal to the product of (A) the Nondissenting Portion times (B) 5,294,783,
and (z) subject to the following provisions of this Section 1.3(a), cash in an
amount equal to the product of (A) the Nondissenting Portion times (B)
177,926,000 reduced by the aggregate amount of cash dividends paid by Denver
pursuant to Section 6.1(b)(iv)(c) prior to the Effective Time (collectively, the
"Merger Consideration"). The "Nondissenting Portion" shall be equal to one minus
a fraction, the numerator of which is the number of Dissenting Shares and the
denominator of which a number of Worldwide Shares (other than Affiliated Shares)
issued and outstanding immediately prior to the Effective Time. In addition, in
connection with the Merger, Starwood Trust will Assume (or cause to be Assumed)
all indebtedness of Worldwide and of each entity set forth on Schedule 1.3(a) in
which Worldwide has a direct or indirect equity interest (including joint
venture indebtedness) (collectively "Worldwide Debt") outstanding immediately
prior to the Effective Date. At the Effective Time, no Worldwide Share shall any
longer be outstanding and all Worldwide Shares shall be canceled and retired and
shall cease to exist, and each certificate (a "Certificate") formerly
representing any of such Worldwide Shares (other than Excluded Shares) shall
thereafter represent only the right to the Merger Consideration and the right,
if any, to receive pursuant to Section 4.1(d) cash in lieu of fractional shares
into which such Worldwide Shares have been converted pursuant to this Section
1.3(a) and any distribution or dividend pursuant to Section 4.1(b).
 
     (b) In the event the principal amount of outstanding indebtedness of the
Westin Subsidiaries and their respective Subsidiaries (excluding any
intercompany indebtedness for borrowed money) immediately prior to the Effective
Date is less than the amount set forth in Schedule 1.3(b), the aggregate amount
of the cash portion of the Merger Consideration shall be increased by an amount
equal to the excess of the amount of such indebtedness set forth in Schedule
1.3(b) over the sum of (i) the principal amount of such indebtedness Assumed
pursuant to Section 1.1 or Section 1.3 and (ii) the amount of any cash paid
pursuant to Section 1.1(f), this Agreement, and each outstanding share of
Worldwide that is converted into a portion of
 
                                        5
<PAGE>   9
 
the Merger Consideration in the Merger shall be converted into its pro rata
portion of such increased Merger Consideration.
 
     (c) In the event that (1) the sum of (i) the principal of and all accrued
and unpaid interest on the outstanding indebtedness of the Members (or their
permitted transferees) that is Assumed by the Starwood Realty Partnership or the
Starwood Operating Partnership pursuant to Section 1.1, (ii) the principal
amount of indebtedness of the Westin Subsidiaries and their respective
Subsidiaries (including the allocable portion of the indebtedness of
non-subsidiary joint ventures) that is Assumed by the Starwood Companies
pursuant to Section 1.1 or Section 1.3 (other than any indebtedness incurred to
fund (a) Actual Scheduled Expenditures in excess of Budgeted Scheduled
Expenditures, (b) Actual Unscheduled Expenditures or (c) acquisitions that, in
any such case, are permitted to be made as a result of the operation of this
Section 1.3 or any indebtedness incurred by any joint venture that is not
controlled by the Westin Companies) and (iii) without duplication of any amounts
described in clause (i) or (ii), any cash paid pursuant to Section 1.1(f)
exceeds the amount set forth in Schedule 1.3(c), then the aggregate amount of
the cash portion of the Merger Consideration shall be decreased by an amount
equal to such excess, and each outstanding share of Worldwide that is converted
into a portion of the Merger Consideration in the Merger shall be converted into
its pro rata portion of such decreased Merger Consideration.
 
     (d) In the event the aggregate amount of capital expenditures or
investments made in respect of the hotels or other assets relating to the Westin
Companies and/or their respective Subsidiaries set forth on Schedule 1.3(d)-1
during the period beginning on January 1, 1997 and ending on December 31, 1997
("Actual Scheduled Expenditures") (calculated in accordance with GAAP (as
defined in Section 1.4(f)) applied on a basis consistent with the Westin
Companies' past practice), is less than the aggregate amount of capital
expenditures or investments for such hotels or other assets set forth on
Schedule 1.3(d)-1 ("Budgeted Scheduled Expenditures"), the cash portion of the
Merger Consideration shall be decreased by an aggregate amount of cash equal to
the sum of all such deficits. For purposes of this Section, the portion of
Actual Capital Expenditures made during the period commencing on January 1, 1997
and ending on June 30, 1997 shall be deemed to be no greater than the amounts
set forth on Schedule 1.3(d)-2.
 
     (e) In the event the amount of Actual Scheduled Expenditures exceeds the
amount of Budgeted Scheduled Expenditures, or in the event that capital
expenditures or investments are made in respect of any hotel or other asset
relating to any of the Westin Companies and/or their respective Subsidiaries
that is not set forth on Schedule 1.3(d)("Actual Unscheduled Expenditures"),
then, subject to the fourth succeeding sentence, the cash portion of the Merger
Consideration shall be increased by an aggregate amount of cash equal to the sum
of all such excesses and amounts of Actual Unscheduled Expenditures less all
such excesses and amounts financed directly or indirectly with indebtedness
Assumed (or caused to be Assumed) by any Starwood Company pursuant to this
Agreement. The Westin Companies hereby agree that at least ten business days
prior to making any Actual Scheduled Expenditure that exceeds the amount of the
related Budgeted Scheduled Expenditure or any Actual Unscheduled Expenditure,
the Westin Companies will provide the Starwood Companies with written notice of
any such proposed expenditure (the "Proposed Expenditure"). Notwithstanding
anything contained herein to the contrary, the Westin Companies shall not make
any Proposed Expenditure unless the Starwood Companies approve such Proposed
Expenditure in writing, except as provided in the second succeeding sentence. In
the event the Starwood Companies do not so approve such Proposed Expenditure
within ten business days after receipt of such notice, representatives of the
Starwood Companies and representatives of the Westin Companies will attempt to
resolve the matter. If such attempt does not result in the resolution of such
matter, either (i) the Westin Companies shall not make such Proposed Expenditure
for so long as this Agreement is in effect or (ii) the Westin Companies may make
such Proposed Expenditure but the cash portion of the Merger Consideration shall
not be increased in respect of such excess. Notwithstanding anything contained
herein to the contrary, (i) any refusal by the Starwood Companies to approve the
making of a Proposed Expenditure must be made by the Starwood Companies in good
faith, (ii) the Starwood Companies shall be deemed to approve the making of a
Proposed Expenditure the amount of which the Starwood Companies agree is
required to be made by the Westin Companies by the terms of any agreement to
which any of the Westin Companies is a party on the date hereof and which
agreement is set forth on Schedule 7.2(a) (it being understood and agreed that
(a) the Starwood Companies
 
                                        6
<PAGE>   10
 
shall not be deemed to have approved any such expenditure in excess of
$1,000,000 if the Starwood Companies determine, in good faith and on a
reasonable basis, that the agreement pursuant to which such expenditure is
proposed to be made does not require the Westin Companies or any of their
Subsidiaries to make such expenditure or that the failure to make such
expenditure would not impose a penalty on any of the Westin Companies or their
Subsidiaries) and (b) the Starwood Companies shall be deemed to have approved
expenditures with respect to the properties located in San Antonio, Texas and
Savannah, Georgia made after June 30, 1997 to the extent that the portion of
such expenditures funded by equity contributions from the Westin Companies does
not exceed $8,890,000 and $240,000 respectively, and to the extent that any
other expenditures in respect of such properties are approved or deemed approved
by operation of this Section 1.3(e), and any Proposed Expenditure made in
connection with a hotel or other item relating to St. John and/or its
Subsidiaries shall be deemed approved by the Starwood Companies except to the
extent the aggregate amount of such Proposed Expenditures for the 1997 calendar
year exceeds $13,200,000.
 
     (f) The Westin Companies agree that, for so long as this Agreement is in
effect, they shall not acquire any assets (other than assets acquired in the
ordinary course of business consistent with past practice or acquisitions of
assets constituting capital expenditures subject to Section 1.3(d) or 1.3(e)) or
securities of any other Person for an aggregate purchase price in excess of
$1,000,000 without the prior written consent of the Starwood Companies;
provided, however, that in the event that the Starwood Companies object to the
making of an acquisition by the Westin Companies pursuant to this Section 1.3(f)
that can, at the time of any objection thereto by the Starwood Companies, be
acquired by the Westin Companies pursuant to the terms of an agreement relating
to such acquisition, subject to the terms and conditions specified in such
agreement, none of the Starwood Companies or any of their Affiliates may,
without the prior written consent of the Members, pursue or make such
acquisition for the account of any of the Starwood Companies or any of their
affiliates for a period of one year after the date, if any, of the termination
of this Agreement. In the event that any of the Westin Companies makes an
acquisition in accordance with the provisions of this Section 1.3(f), the cash
portion of the Merger Consideration shall be increased by an aggregate amount
equal to the purchase price (other that any portion thereof that is financed by
indebtedness that is assumed by the Starwood Companies) and transaction costs
paid in connection with such acquisition.
 
     (g) At the election of the Westin Companies, the parties will amend this
Agreement to provide that the stockholders of Worldwide and each of the other
Westin Companies may elect to receive different forms of the consideration to be
issued in connection with the Merger and the Subsidiary Contributions provided
that the aggregate amount of each of the Class A EPS, the Class B EPS, Starwood
Realty Partnership Units, Starwood Operating Partnership Units and cash to be
issued in the Merger and each of the Subsidiary Contributions shall not be
altered by such amendment, and each of the parties hereto agrees that in the
event the Westin Companies exercise such option, they will promptly execute and
deliver such amendment and such other documents as may be reasonably requested
by the Westin Companies to effect such amendment; provided, however, that any
amendment to this Agreement made pursuant to this Section 1.3(g) shall not
adversely affect the ability of the Merger to constitute a "reorganization"
within the meaning of the Code or adversely affect the REIT status of Starwood
Trust.
 
     (h) Cancellation of Worldwide Shares. Each Excluded Share (that is not a
Dissenting Share) issued and outstanding immediately prior to the Effective
Time, shall, by virtue of the Merger and without any action on the part of the
holder thereof, cease to be outstanding, shall be canceled and retired without
payment of any consideration therefor and shall cease to exist.
 
     1.4. WORKING CAPITAL ADJUSTMENTS
 
     (a) At least two business days prior to the Closing Date, the Westin
Companies shall prepare, based on the Westin Companies' books and records and
other information then available, and deliver to the Starwood Companies a
consolidated balance sheet (each an "Estimated Working Capital Balance Sheet")
prepared in accordance with GAAP consistent with the Westin Companies' past
practice (except as provided herein) and setting forth an estimate of the
aggregate Working Capital as of the Closing Date (each, an "Estimated Working
Capital") for each of (i) Worldwide and its Subsidiaries, (ii) Lauderdale and
its Subsidiaries,
 
                                        7

(iii) Seattle and its Subsidiaries, (iv) Denver and its Subsidiaries (v) Atlanta
and its Subsidiaries and (vi) St. John and its Subsidiaries (each, a "Westin
Group").
 
     If the Estimated Working Capital for Worldwide and its Subsidiaries exceeds
zero, the cash portion of the Merger Consideration shall be increased by the
amount of such excess. In the event the Estimated Working Capital for Worldwide
and its Subsidiaries is less than zero, the cash portion of the Merger
Consideration shall be decreased by the amount of such deficit.
 
     If the Estimated Working Capital for any Westin Group other than Worldwide
and its Subsidiaries exceeds zero, the Starwood Companies shall deliver to the
LLC or the stockholders of the Westin Subsidiary of such Westin Group,
concurrently with the Subsidiary Contribution in respect of such Westin Group,
an amount in cash equal to the amount of such excess. If the Estimated Working
Capital for any Westin Group other than Worldwide and its Subsidiaries is less
than zero, LLC or the stockholders of such Westin Group shall deliver to the
applicable Starwood Company, concurrently with the Subsidiary Contribution in
respect of such Westin Group, an amount in cash equal to the amount of such
deficit.
 
     In the event the Estimated Working Capital for any Westin Group is zero,
the cash portion of the Merger Consideration (in the case of Worldwide and its
Subsidiaries) or the Subsidiary Contribution relating to such Westin Group (in
the case of any Westin Group other than Worldwide and its Subsidiaries), as
applicable, shall not be adjusted.
 
     (b) As promptly as practicable, but no later than 90 days after the Closing
Date, the Starwood Companies shall cause their accountants, Coopers & Lybrand,
to prepare and deliver to the LLC and its accountants, Arthur Andersen, a
consolidated balance sheet of each of the Westin Groups (collectively, the
"Closing Balance Sheets"), together with a report of Coopers & Lybrand thereon,
for the purpose of establishing the Closing Working Capital for each Westin
Group. The Closing Balance Sheets shall reflect the Current Assets and Current
Liabilities of each Westin Group as of the close of business on the Closing Date
and shall be prepared on a basis consistent with that required hereby to be used
in the preparation of the relevant Estimated Working Capital Balance Sheet.
 
     (c) If the Closing Working Capital for any Westin Group exceeds the
Estimated Working Capital for such Westin Group, Starwood Trust, Starwood Realty
Partnership or Starwood Operating Partnership, as applicable, shall, subject to
subsection (d) of this Section 1.4, deliver to the stockholders of such Westin
Group an aggregate amount in cash equal to the amount of such excess. If the
Closing Working Capital for any Westin Group is less than Estimated Working
Capital for such Westin Group, each of the stockholders of such Westin Group
shall, subject to subsection (d) of this Section 1.4, deliver to Starwood Trust,
Starwood Realty Partnership or Starwood Operating Partnership, as applicable,
such stockholder's pro rata portion an aggregate amount in cash equal to the
amount of such deficit. In the event the Closing Working Capital for any Westin
Group equals the Estimated Working Capital for such Westin Group, no adjustment
shall be made pursuant to this clause (c).
 
     All amounts owed pursuant to this subsection (c) and subsection (d) of this
Section 1.4 shall include interest, from and including the Closing Date to but
excluding the date of payment, at a rate per annum equal to the rate of interest
announced by Citibank, N.A. from time to time as its Prime or Base Rate in New
York City in effect from time to time.
 
     (d) If the LLC disagrees with any items on the Closing Balance Sheet for
any Westin Group, the LLC shall notify the Starwood Companies in writing of such
disagreement within 30 days after the Starwood Companies' receipt thereof, and
such notice shall set forth the basis for such disagreement in reasonable
detail. During such 30-day period, the Starwood Companies shall afford the LLC
and its duly designated representatives access to all the Starwood Companies'
books and records and cause the Starwood Companies' accountants to afford the
LLC and its duly designated representatives access to all the work papers of the
Starwood Companies' accountants during regular business hours as required by the
LLC to review the Closing Balance Sheet for such Westin Group in each case
solely for purposes of resolving such disagreement, and the LLC shall not,
directly or indirectly, use or permit any of its Affiliates (as defined in
Section 9.12(b)) to use such information for any other purpose or disclose or
permit any of its Affiliates to disclose such information to
 
                                        8
<PAGE>   12
 
any other Persons, except as required by law or court order. The LLC and the
Starwood Companies shall thereafter negotiate in good faith to resolve any such
disagreements; provided that the Starwood Companies shall promptly pay to the
LLC, or the LLC shall promptly pay to the Starwood Companies, as the case may
be, the amount, if any, determined pursuant to subsection (c) that is not
subject to dispute. If the LLC and the Starwood Companies are unable to resolve
any such disagreements within 30 days after the LLC's receipt of the Starwood
Companies' notice described above, the LLC and the Starwood Companies shall
select an Auditor to resolve the disagreements in accordance with subsection (e)
of this Section 1.4.
 
     (e) The "Auditor" shall be a "big six" nationally recognized certified
public accounting firm mutually selected by the respective accounting firms of
the LLC and the Starwood Companies solely to resolve only those disputed items
in accordance with the terms of this Agreement. The LLC and the Starwood
Companies shall use their reasonable best efforts to cause the Auditor to
resolve all disagreements on the disputed items as soon as practicable; provided
that the Auditor shall be bound by the provisions of this Section 1.4 and shall
not assign a value to any item greater than the greatest value for such item
claimed by either party or less than the smallest value for such item claimed by
either party. Each of the LLC and the Starwood Companies shall permit the
Auditor to have full access to their books, records, key employees and
independent accountants in order to resolve any such disagreements. The
resolution of such disagreements by the Auditor shall be final and binding on
the LLC and the Starwood Companies. The fees and expenses of the Auditor shall
be paid by the party whose position is most at variance with the decision of the
Auditor, as such person shall be determined by the Auditor.

                         REPRESENTATIONS AND WARRANTIES
 
     5.1. REPRESENTATIONS AND WARRANTIES OF THE WESTIN COMPANIES. Each of the
LLC and the Members hereby represents and warrants to the Starwood Companies
that:
 
     (a) Organization, Good Standing and Qualification. Each of the Westin
Companies, and each of their respective Subsidiaries is a limited liability
company, corporation or partnership duly organized, validly existing and in good
standing under the laws of its respective jurisdiction of organization and has
all requisite corporate, limited liability company or partnership power and
authority to own and operate its properties and assets and to carry on its
business as presently conducted; each is qualified to do business and is in good
standing as a foreign corporation, limited liability company or partnership in
each jurisdiction where the ownership or operation of its properties or conduct
of its business requires such qualification, except where the failure to be so
qualified or in good standing, when taken together with all other such failures,
is not reasonably likely to have a Westin Material Adverse Effect (as defined
below). The Westin Companies have made available to the Starwood Companies
complete and correct copies of the certificate of formation of the LLC and the
certificates of incorporation and by-laws, each as amended to date, of each of
the Westin Subsidiaries and each of their Subsidiaries. The certificate of
formation of the LLC and certificates of incorporation and by-laws of the Westin
Subsidiaries and their respective Subsidiaries so made available are in full
force and effect.
 
     As used in this Agreement, the term (i) "Subsidiary" means, with respect to
any Westin Company or any Starwood Company, as the case may be, any entity,
whether incorporated or unincorporated, of which at least a majority of the
securities or ownership interests having by their terms ordinary voting power to
elect a majority of the Board of Directors or other persons performing similar
functions is directly or indirectly owned or controlled by such party or by one
or more of its respective Subsidiaries or by such party and any one or more of
its respective Subsidiaries and (ii) "Westin Material Adverse Effect" means a
material adverse change in or effect on (or any development that would likely
result in such change or effect on) the financial condition, properties,
business, results of operations or prospects of the Westin Companies and their
Subsidiaries taken as a whole; provided, however, that any such effect resulting
from any change in law, rule or regulation or GAAP or interpretations thereof
that applies to both the Starwood Companies and the Westin Companies shall not
be considered when determining if a Westin Material Adverse Effect has occurred.
 
     (b) Capital Structure. The authorized capital stock of Lauderdale, Seattle,
St. John, Atlanta, Denver and Worldwide consists solely of 2,000,000, 2,000,000,
1000, 100, 100 and 2,000,000 shares of common stock, respectively, of which
987,931.4, 987,931.4, 10, 100, 100 and 987,931.4 shares of common stock were
outstanding as of the date hereof. All the outstanding capital stock of
Lauderdale, Seattle, St. John, Denver, Atlanta and Worldwide has been duly
authorized and is validly issued, fully paid and nonassessable and, except as
set forth in Section 5.1(b) of the disclosure letter delivered to the Starwood
Companies by the Westin Companies and the Members on or prior to entering into
this Agreement (the "Westin Disclosure Letter")(it being understood and agreed
that the inclusion of an item on the Westin Disclosure Letter shall not
constitute an admission by the Westin Companies that such item is required to be
set forth therein in response to the representation and warranty that
corresponds to such section of the Westin Disclosure Letter), owned beneficially
by the LLC. Lauderdale, Seattle, St. John, Atlanta, Denver and Worldwide have no
shares of capital stock reserved for issuance, except that, as of the date
hereof, Juergen Bartels, Frederick J. Kleisner and Richard L. Mahoney hold
options to purchase shares of Worldwide, Seattle and Lauderdale pursuant to
their respective employment and related agreements, all of which shall either
have been exercised or terminated immediately prior to the Effective Time.
Except as set forth in Section 5.1(b) of the Westin Disclosure Letter, each of
the outstanding shares of capital stock or other securities of each of the
Subsidiaries of the Westin Subsidiaries is duly authorized, validly issued,
fully paid and nonassessable and, except for directors' qualifying shares, owned
directly or indirectly by Lauderdale, Seattle, St. John, Atlanta, Denver and
Worldwide, free and clear of any lien, pledge, security interest, claim or other
encumbrance. Except as set forth above, there are no preemptive or other
outstanding rights (other than with respect to wholly-owned subsidiaries),
options, warrants, conversion rights, stock appreciation rights, redemption
rights, repurchase
 
                                       15

capital stock or other securities of the Westin Subsidiaries or any of their

exchangeable into or exercisable for, or giving any Person a right to subscribe
for or acquire, any securities of Lauderdale, Seattle, St. John, Atlanta, Denver
or Worldwide or any of their respective Subsidiaries, and no securities or
obligations evidencing such rights are authorized, issued or outstanding. None

bonds, debentures, notes or other obligations the holders of which have the
right to vote (or that are convertible into or exercisable for securities having
the right to vote) with the stockholders, members or partners, as the case may
be, of any of the Westin Subsidiaries or any of their Subsidiaries on any matter
("Westin Voting Debt"). At June 30, 1997, the aggregate principal amount of the
Worldwide Debt (without inclusion of any indebtedness of Westin Hotels Limited
Partnership, Westin Chicago Limited Partnership, Westin St. Francis Limited

contemplated hereby. This Agreement is a valid and binding agreement of each of
the Members and the Westin Companies enforceable against each of the Members and
the Westin Companies in accordance with its terms, subject to bankruptcy,
insolvency, fraudulent transfer, reorganization, moratorium and similar laws of
general applicability relating to or affecting creditors' rights and to general
equity principles (the "Bankruptcy and Equity Exception").

Agreement and the other transactions contemplated hereby and the Board of

required to be obtained by any of the Members or the Westin Companies from, any
governmental or regulatory authority, agency, commission, court, body or other
governmental entity ("Governmental Entity"), in connection with the execution
and delivery of this Agreement by the Members and the Westin Companies and the
consummation by Worldwide of the Merger and by the Members and the Westin
Companies of the other transactions contemplated hereby, except those that the
failure to make or obtain are not, individually or in the aggregate, reasonably
likely to have a Westin Material Adverse Effect or prevent, materially delay or
materially impair the ability of Worldwide to consummate the Merger or the
Westin Companies to consummate the transactions contemplated by this Agreement.
 
     (ii) Except as set forth in Section 5.1(d) of the Westin Disclosure Letter,
the execution, delivery and performance of this Agreement by the Members and the
Westin Companies, the consummation by Worldwide of the Merger and the
consummation by the Members and the Westin Companies of the other transactions
contemplated hereby will not constitute or result in (A) a breach or violation
of, or a default under, the respective certificates of formation, limited
liability company agreement or partnership agreement of the Members or the LLC
or the respective certificates of incorporation or by-laws of the Westin
Subsidiaries or the comparable governing instruments of any of their
Subsidiaries, (B) a breach or violation of, or a default or the loss of any
material benefit under, or the acceleration of any obligations or the creation

time or both) pursuant to, any agreement, lease, contract, note, mortgage,
indenture, license, arrangement or other obligation not otherwise terminable by
the other party

Companies or any of their Subsidiaries is subject or (C) any change in the
rights or obligations of any party under any of the Westin Contracts, except, in
the case of clause (B) or (C) above, for any breach, violation, default, loss of
benefits, acceleration, creation or change that, individually or in the
aggregate, is not reasonably likely to have a Westin Material Adverse Effect or

consummate the Merger or the Westin Companies to consummate the transactions
contemplated by this Agreement.

arrangement that covers employees, directors, former employees or former
directors of the Westin Companies and their Subsidiaries (the"Compensation and
Benefit Plans") and any trust arrangements or insurance contract forming a part
of such Compensation and Benefit Plans has been "furnished" (it being understood
that the term "furnished" shall be deemed to include, but not be limited to, the

Westin Companies and their Subsidiaries relating to any anticipated increases in

any withdrawal liability or hypothetical withdrawal liability under Section 4201
of ERISA of any ERISA Affiliate.
 
     (ii) All Compensation and Benefit Plans are in substantial compliance with

meaning of Section 3(2) of ERISA (a "Pension Plan") and that is intended to be
qualified under Section 401(a) of the Code has received a favorable
determination letter from the Internal Revenue Service (the "IRS") or such
determination letter request has been or will be filed with the IRS prior to the
end of the any applicable remedial/amendment period, and the Westin Companies
are not aware of any event that would adversely affect such qualification. None
of the Westin Companies nor any of their Subsidiaries has engaged in a
transaction with respect to any Compensation and Benefit Plan that, assuming the
taxable period of such transaction expired as of the date hereof, would subject
the Westin Companies or any of their Subsidiaries to a material tax or penalty
imposed by either Section 4975 of the Code or Section 502 of ERISA.
 
     (iii) As of the date hereof, no liability under Subtitle C or D of Title IV

employer plan, within the meaning of Section 4001(a)(15) of ERISA (a "Single
Employer Plan"). To the knowledge of the Westin Companies, no proceeding has
been initiated to terminate any Multiemployer Plan. To the knowledge of the
Westin Companies, no Multiemployer Plan is in reorganization as described in
Section 4241 of ERISA or insolvent as described in Section 4245 of ERISA. Except
as disclosed in Section 5.1(h) of the Westin Disclosure Letter, none of the
Westin Companies, their Subsidiaries or, to the knowledge of the Westin

disputed contribution to any Multiemployer Plan. None of the Westin Companies,
their Subsidiaries or, to the knowledge of Westin Companies, ERISA Affiliates is
bound by a contract or agreement or has any obligation or liability described in
Section 4204 of ERISA. No notice of a "reportable event", within the meaning of
Section 4043 of ERISA for which the 30-day reporting requirement has not been
waived, has been required to be filed for any Pension Plan or, to the knowledge
of Westin Companies, by any ERISA Affiliate within the 12-month period ending on
the date hereof.
 
     (iv) All contributions required to be made under the terms of any
Compensation and Benefit Plan as of the date hereof have been timely made or
have been reflected on the most recent consolidated balance sheet provided to
Starwood Trust prior to the date hereof. Neither any Pension Plan nor any Single
Employer Plan of an ERISA Affiliate has an "accumulated funding deficiency"
(whether or not waived) within the meaning of Section 412 of the Code or Section
302 of ERISA. None of the Westin Companies nor any of their Subsidiaries has

determined on the basis of the actuarial assumptions contained in the Pension
Plan's most recent actuarial valuation), did not exceed the then current value
of the assets of such Pension Plan, and there has been no material change in the
financial condition of such Pension Plan since the last day of the most recent
plan year.
 
     (vi) None of the Westin Companies nor any of their Subsidiaries has any
obligation for retiree health and life benefits under any Compensation and
Benefit Plan, except as set forth in Section 5.1(h) of the Westin Disclosure
Letter. Except as disclosed in Section 5.1(h)(vi) of the Westin Disclosure
Letter, the Westin Companies or their Subsidiaries may amend or terminate any
such plan under the terms of such plan at any time without incurring any
material liability thereunder.
 
     (vii) Except as disclosed in Section 5.1(h)(vii) of the Westin Disclosure
Letter, all Compensation and Benefit Plans covering current or former non-U.S.

respects with applicable local law. The Westin Companies and their Subsidiaries
have no material unfunded liabilities with respect to any Pension Plan that
covers such non-U.S. employees, in excess of the amount reserved therefor.

     Lease, nor, to the knowledge of the Westin Companies, any other party to
     such Space Lease is in breach or default under such Space Lease, except in

consummate, subject only to any stockholder approval required by the laws of the
State of Maryland and the rules of the New York Stock Exchange (the "Starwood
Trust Requisite Vote"), the Merger and the other transactions contemplated by
this Agreement. This Agreement is a valid and binding agreement of each of the
Starwood Companies, enforceable against each of the Starwood Companies in

     (ii) The Special Committee of the Starwood Disinterested Trustees of the

received the opinion of its financial advisors, Morgan Stanley & Co.
Incorporated, to the effect that the consideration to be paid by the Starwood
Trust in the Merger and by the other Starwood Companies in the other
transactions contemplated hereby is fair to the stockholders of Starwood Trust
and Starwood Corp., a copy of which opinion has been delivered to the LLC. It is
agreed and understood that such opinion is for the benefit of the Special
Committee of Starwood Disinterested Trustees of the Board of Trustees of
Starwood Trust and the Special Committee of the Starwood Disinterested Directors
of the Board of Directors of Starwood Corp. and may not be relied on by the
Westin Companies. The Board of Trustees of Starwood Trust and the Board of
Directors of Standard Corp. have unanimously approved this Agreement and the
Merger and the other transactions contemplated hereby.
 
     (iii) Prior to the Effective Time, Starwood Trust will have taken all

nonassessable, and no stockholder or unitholder, as applicable, of Starwood
Trust, Starwood Corp., Starwood Realty Partnership or Starwood Operating

Securities Exchange Act of 1934, as amended (the "Exchange Act"), (C) to comply
with state securities or "blue sky" laws and (D) required to be made with the

execution and delivery of this Agreement by the Starwood Companies and the
consummation by the Starwood Companies of the transactions contemplated hereby
and by Starwood Trust of the Merger, except those that the failure to make or

Starwood Material Adverse Effect or prevent, materially delay or materially
impair the ability of the Starwood Companies to consummate the transactions
contemplated by this Agreement.
 
     (ii) The execution, delivery and performance of this Agreement by the
Starwood Companies does not, and the consummation by the Starwood Companies of
the transactions contemplated hereby and by Starwood Trust of the Merger will
not, constitute or result in (A) a breach or violation of, or a default under,

Trust Regulations, partnership or by-laws of the Starwood Companies or the
comparable governing instruments of any of their Subsidiaries, (B) a breach or

ability of the Starwood Companies to consummate the transactions contemplated by
this Agreement.
 
     (e) Starwood Trust and Starwood Corp. Reports; Financial
Statements. Starwood Trust and Starwood Corp. have made and will make all

respective dates, the Starwood Reports did not, and any Starwood Reports filed
with the SEC subsequent to the date hereof will not, contain any untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements made therein, in light of the
circumstances in which they were made, not misleading. Each of the consolidated

fairly present, the consolidated financial position of Starwood Trust and
Starwood Corp. and their Subsidiaries as of its date and each of the

effect), in each case in accordance with GAAP consistently applied during the
periods involved, except as may be noted therein.

filed prior to the date hereof, there are no civil, criminal or administrative
actions, suits, claims, hearings, investigations or proceedings pending or, to
the knowledge of Starwood Trust and Starwood Corp., threatened against the
Starwood Companies or any of their Affiliates that could result in any claims
against, or obligations or liabilities of, the
 
                                       32
<PAGE>   36
 
Starwood Companies or any of the Affiliates, except for those that are not,
individually or in the aggregate, reasonably likely to have a Starwood Material
Adverse Effect or prevent or materially burden or materially impair the ability
of the Starwood Companies to consummate the transactions contemplated by this
Agreement.
 
     (g) Takeover Statutes. No Takeover Statute or any applicable anti-takeover

     (h) Tax Matters. As of the date hereof, none of the Starwood Companies or
any of their Affiliates has taken or agreed to take any action, nor do Starwood

investment trust" within the meaning of Section 856 of the Code.
 
     (i) Taxes. Except as set forth in the Starwood Reports filed prior to the

each of the Starwood Companies, each of their Subsidiaries and each Starwood
Affiliated Group has filed all Tax Returns required to be filed; (ii) all such
Tax Returns are complete and accurate and disclose all Taxes required to be paid
by each of the Starwood Companies, each of their Subsidiaries and each Starwood
Affiliated Group for the periods covered thereby and all Taxes shown to be due
on such Tax Returns have been timely paid; (iii) all Taxes (whether or not shown
on any Tax Return) owed by any of the Starwood Companies, any of their
Subsidiaries or any Starwood Affiliated Group have been timely paid; (iv) none
of any of the Starwood Companies, any of their Subsidiaries or any member of any
Starwood Affiliated Group has waived or been requested to waive any statute of
limitations in respect of Taxes which waiver is currently in effect; (v) the Tax
Returns referred to in clause (i), to the extent related to income Taxes, have
been examined by the appropriate taxing authority or the period for assessment
of the Taxes in respect of which such Tax Returns were required to be filed has
expired; (vi) there is no action, suit, investigation, audit, claim or
assessment pending or proposed or threatened with respect to Taxes of any of the
Starwood Companies, any of their Subsidiaries or any Starwood Affiliated Group;
(vii) all deficiencies asserted or assessments made as a result of any
examination of the Tax Returns referred to in clause (i) have been paid in full;
(viii) there are no liens for Taxes upon the assets of any of the Starwood
Companies or any of their Subsidiaries except liens relating to current Taxes
not yet due; (ix) all Taxes which any of the Starwood Companies, any of their
Subsidiaries or any Starwood Affiliated Group are required by law to withhold or
to collect for payment have been duly withheld and collected, and have been paid
or accrued, reserved against and entered on the books of the Starwood Companies.
 
     As used in this Agreement, the term "Starwood Affiliated Group" means any
"affiliated group" (as defined in Section 1504(a) of the Code without regard to
the limitations contained in Section 1504(b) of the Code) that, at any time on
or before the Effective Time, includes or has included any of the Starwood
Companies or any of their Subsidiaries or any predecessor of or successor to any
of the Starwood Companies or any of their Subsidiaries (or another such
predecessor or successor), or any other group of corporations which, at any time
on or before the Closing Date, files or has filed Tax Returns on a combined,
consolidated or unitary basis with any of the Starwood Companies or any of their
Subsidiaries or any predecessor of or successor to any of the Starwood Companies
or any of their Subsidiaries (or another such predecessor or successor).
 
     (j) Brokers and Finders. None of the Starwood Companies and none of their
officers, directors or employees has employed any broker, agent or finder or
incurred any liability for any brokerage fees, commissions or finders' fees in
connection with the Merger or the other transactions contemplated by this
Agreement, except that Starwood Trust has employed Morgan Stanley & Co.
Incorporated as its financial advisor, the fees of which shall be paid by the
Starwood Companies.

     (k) "REIT" Status. Starwood Trust is currently a "real estate investment
trust" ("REIT") for federal income tax purposes. From and after January 1, 1995,
neither the IRS nor any other taxing entity or authority has made any assertion
that Starwood Trust does not qualify as a REIT for income tax purposes, nor has
there been any challenge to the REIT status of Starwood Trust.
 
     (l) "Partnership" Status. Each of Starwood Realty Partnership and Starwood
Operating Partnership is classified and taxable as a partnership for U.S.
federal income tax purposes.
 
     (m) Starwood Report Disclosure. The Starwood Reports, taken as a whole, do
not contain 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 or include an untrue statement of a material fact or omit to
state a material fact necessary in order to make the statements, in light of the
circumstances under which they were made, not misleading.

copies of notice or other communications received by the Starwood Companies or
the Westin Companies, as the case may be, or any of their respective
Subsidiaries, from any third party and/or any Governmental Entity with respect
to the Merger and the other transactions contemplated by this
 
                                       37
<PAGE>   41
 
Agreement. The Westin Companies and the Starwood Companies each shall give
prompt notice to the other of (i) any change that is reasonably likely to result
in a Westin Material Adverse Effect or Starwood Material Adverse Effect,
respectively, (ii) any notice or other communication from any third Person
alleging that the consent of such third Person is or may be required in
connection with the transactions contemplated by this Agreement, and (iii) any
material default under any Contract or event which, with notice or lapse of time
or both, would become such a default on or prior to the Closing Date or
Effective Time and of which any of the Westin Companies has knowledge. Without
limitation of the foregoing, the Starwood Companies shall give the LLC notice of
any breach by the Westin Companies of any of the provisions of this Agreement,
of the failure of the Westin Companies to satisfy any of the conditions to the
obligation of the Starwood Companies to consummate the transactions contemplated
by this Agreement, or of any change or development that is likely to result in
any such breach by the Westin Companies or any such failure by the Westin
Companies to satisfy any such condition promptly upon the Starwood Companies'
learning of such breach, failure or development from a source other than the
Westin Companies.
 
     (f) Without limiting the generality of the undertakings pursuant to this
Section 6.5, the Westin Companies and the Starwood Companies agree (i) to
provide promptly to any and all federal, state, local or foreign court or
Government Entity with jurisdiction over enforcement of any applicable antitrust
laws ("Government Antitrust Entity") information and documents requested by any
Government Antitrust Entity or necessary, proper or advisable to permit
consummation of the Merger and the transactions contemplated by this Agreement
and (ii) take promptly, in the event that any permanent or preliminary
injunction or other order is entered or becomes reasonably foreseeable to be
entered in any proceeding that would make consummation of the Merger or the
other transaction contemplated hereby in accordance with the terms of this
Agreement, any and all reasonable steps, including the appeal thereof or the
posting of a bond necessary to vacate, modify or suspend such injunction or
order, so as to permit such consummation on a schedule as close as possible to
that contemplated by this Agreement; provided, however, that the foregoing shall
not require the Starwood Companies or the Westin Companies to make any
divestiture or consent to any divestiture in order to fulfill any condition or
obtain any consent, authorization or approval or to appeal an injunction or
order, or to post a bond in respect of such appeal, that is not economically
reasonable for the Starwood Companies.
 
     6.6. TAX MATTERS (a) None of the Westin Companies or the Starwood Companies
shall take or cause to be taken any action, whether before or after the
Effective Time, that would disqualify the Merger as a "reorganization" within
the meaning of Section 368(a) of the Code.
 
     (b) Each of the Starwood Companies will use their best efforts to maintain
REIT status, for U.S. federal income tax purposes, of Starwood Trust from the
date hereof through December 31, 1998 and the partnership status, for U.S.
federal income tax purposes, of each of Starwood Realty Partnership and Starwood
Operating Partnership from the date hereof through the tenth anniversary of the
Closing Date. None of the Starwood Companies will take any action that would
adversely affect the ability of Starwood Trust to qualify as a REIT for U.S.
federal income tax purposes from the date hereof through December 31, 1998 and
for each of Starwood Realty Partnership and Starwood Operating Partnership to be
classified and taxable as a partnership for U.S. federal income tax purposes
from the date hereof through the tenth anniversary of the Closing Date.
 
     6.7. ACCESS. Upon reasonable notice, and except as may otherwise be
required by applicable law, each of the Westin Companies and the Starwood
Companies shall (and shall cause its Subsidiaries to) afford the other's
officers, employees, counsel, accountants and other authorized representatives
("Representatives") access, during normal business hours throughout the period
prior to the Closing Date, to its properties, books, contracts and records and,
during such period, each shall (and shall cause its Subsidiaries to) furnish
promptly to the other all information concerning its business, properties and
personnel as may reasonably be requested, provided that no investigation
pursuant to this Section shall affect or be deemed to modify any representation
or warranty made by any Westin Company or any Starwood Company, and provided,
further, that the foregoing shall not require any Westin Company or Starwood
Company to permit any inspection, or to disclose any information, that in the
reasonable judgment of such Westin Company or Starwood Company, as the case may
be, would result in the disclosure of any trade secrets of third parties or
violate any of its obligations with respect to confidentiality if such Westin
Company or Starwood Company, as the case may be, shall have used best efforts to
obtain the consent of such third party to such inspection or disclosure. All
requests for
 
                                       38
<PAGE>   42
 
information made pursuant to this Section shall be directed to an executive
officer of the LLC or Starwood Trust, as the case may be, or such Person as may
be designated by either of its officers, as the case may be. Prior to the
Effective Date, the Westin Companies shall deliver to the Starwood Companies,
not later than 45 days after the end of each monthly period and in the form
customarily prepared by the Westin Companies, the unaudited combined
consolidated internal financial statements of the Westin Subsidiaries, including
an income statement, balance sheet and cash flow statement for the monthly
period then ended and for the period from the beginning of the current fiscal
year to the end of such monthly period. All such information shall be governed
by the terms of the Confidentiality Agreement.
 
     For a period of six years after the Effective Date, the LLC and its
representatives shall have reasonable access to all the books and records of the
Westin Companies with respect to periods prior to the Closing Date to the extent
that such access may reasonably be required by the LLC in connection with
matters relating to or affected by the operations of any of the Westin Companies
prior to the Closing Date. The Starwood Companies shall afford such access upon
receipt of reasonable advance notice and during normal business hours. The LLC
shall be solely responsible for any costs or expenses incurred by it pursuant to
this Section 6.7. If any of the Westin Companies shall desire to dispose of any
of such books and records prior to the expiration of such six-year period, the
Westin Companies, prior to such disposition, shall give the LLC a reasonable
opportunity, at the LLC's expense, to segregate and remove such books and
records as the LLC may select.
 
     For a period of six years after the Closing Date, the Starwood Companies
and their respective representatives shall have reasonable access to all the
books and records relating to any of the Westin Companies or their assets or
business which the LLC or any of the Members or their Affiliates may retain
after the Effective Time. Such access shall be afforded by the LLC, the Members
and their Affiliates upon receipt of reasonable advance notice and during normal
business hours. The Starwood Companies shall be solely responsible for any costs
and expenses incurred by it pursuant to this Section 6.7. If any of the LLC or
the Members or any of their Affiliates shall desire to dispose of any of such
books and records prior to the expiration of such six-year period, the LLC or
such Members shall, prior to such disposition, give the Starwood Companies a
reasonable opportunity, at the Starwood Companies' expense, to segregate and
remove such books and records as the Starwood Companies may select.
 
     6.8. AFFILIATES. Prior to the Effective Time, each Westin Company shall
deliver to Starwood Trust a list of names and addresses of those Persons who
are, in the opinion of such Westin Company, as of the time of the Stockholders
Meeting, "affiliates" of such Westin Company within the meaning of Rule 145
under the Securities Act. Each Westin Company shall provide to Starwood Trust
such information and documents as Starwood Trust shall reasonably request for
purposes of reviewing such list. There shall be added to such list the names and
addresses of any other Person subsequently identified by either Starwood Trust
or such Westin Company as a Person who may be deemed to be such an affiliate of
such Westin Company; provided, however, that no such Person identified by
Starwood Trust shall be added to the list of affiliates of such Westin Company
if Starwood Trust shall receive from such Westin Company, on or before the date
of the Stockholders Meeting, an opinion of counsel reasonably satisfactory to
Starwood Trust to the effect that such Person is not such an affiliate. Each
Westin Company shall exercise its best efforts to deliver or cause to be
delivered to Starwood Trust, prior to the date of the Stockholders Meeting, from
each affiliate of a Westin Company identified in the foregoing list (as the same
may be supplemented as aforesaid), a letter dated as of the Closing Date
substantially in the form attached as Exhibit A (the "Affiliates Letter").
 
     6.9. REGISTRATION AND STOCK EXCHANGE LISTING. Starwood Trust and Starwood
Corp. shall use all reasonable efforts to cause the Starwood Paired Shares into
which the Class A EPS, Class B EPS, Starwood Realty Partnership Units and
Starwood Operating Partnership Units issued in the Merger or the other
transactions contemplated by this Agreement are exchangeable to be registered by
filing a registration statement with the SEC and approved for listing on the
NYSE subject to official notice of issuance, pursuant to the Registration Rights
Agreement.
 
     6.10. PUBLICITY. The initial disclosure of the transactions contemplated
hereby shall be a joint press release in the form of Annex D hereto. Except as
otherwise required by applicable law or the rules or regulations of any
securities exchange on which the securities of such party are listed or traded,
no party or any
 
                                       39
<PAGE>   43
 
of its affiliates shall issue or cause the publication of any press release or
other public announcement or disclosure with respect to the transactions
contemplated by this Agreement without the consent of each other party, and in
any event, each party agrees that it shall give each other party reasonable
opportunity to review and comment upon any such release or announcement prior to
publication of the same provided, however, the Starwood Companies and the Westin
Companies shall be free to make comments to their stockholders, shareholders,
employees, and owners of hotels with which such companies or their affiliates
have management, franchise, license or similar agreements, and to financial
analysts and the press which are substantially consistent with disclosures in
all such permitted press releases or announcements.
 
     6.11. OPTIONS; BENEFITS.
 
     (a) Stock Options. Prior to the Effective Time, each of the Westin
Companies shall take such actions as may be necessary such that immediately
prior to the Effective Time each Westin Company Option, whether or not then
exercisable, shall be exercised for securities of the Westin Companies, it being
understood that (i) 60% of such securities so issued in connection with such
exercises of Westin Company Options shall be "vested" for purposes of the
employment agreements pursuant to which such Westin Company Options were issued
and (ii) 40% of such securities so issued in connection with such exercises of
Westin Company Options shall be "unvested" for purposes of the employment
agreements pursuant to which such Westin Company Options were issued and that
any Starwood Securities issued in the transactions contemplated by this
Agreement in respect of such "unvested" securities will be deemed to be
"unvested" in a manner similar to that set forth in such employment agreements
with the first 50% of such unvested securities to vest on May 12, 1998 and the
remaining 50% of such unvested securities to vest on May 12, 1999.
 
     (b) Employee Benefits. Each of Starwood Trust and Starwood Corp. agrees
that each of Starwood Trust and Starwood Corp. shall maintain for a period of
twelve months immediately following the Effective Time, employee benefit plans,
programs, policies and arrangements for employees of the Westin Companies and
their Subsidiaries and employees of unaffiliated companies that have the
benefits of plans administered by the Westin Companies ("Adopting
Non-Affiliates") Adopting Non-Affiliates which in the aggregate are no less
favorable than the employee benefit plans, programs, policies and arrangements
of the Westin Companies and their Subsidiaries in effect on the Effective Time,
in which such employees are eligible to participate immediately preceding the
Effective Time. Starwood Trust and Starwood Corp. will cause such employee
benefit plans to take into account for purposes of eligibility and vesting
thereunder service by employees of the Westin Companies and their Subsidiaries
and employees of Adopting Non-Affiliates as if such service were with Starwood
Trust or Starwood Corp. Starwood Trust and Starwood Corp. shall honor all
employee benefit obligations to current and former employees (including
employees of Adopting Non-Affiliates) under the Compensation and Benefit Plans
and all employee severance plans (or policies) in existence on the date hereof
and all employment or severance agreements entered into by the Westin Companies
or adopted by the Board of Directors or Board of Managers, as applicable, of
each Westin Company prior to the date hereof. Nothing in this Agreement shall be
interpreted as limiting the power of Starwood Trust or Starwood Corp. to cause
the amendment or termination of any Compensation and Benefit Plan, any other
individual employee benefit plan, program, agreement or policy or as requiring
Starwood Trust or Starwood Corp. or their Subsidiaries to offer to continue
(other than as required by its terms) any written employment contract, so long
as in the aggregate Starwood Trust and Starwood Corp. comply with this Section
6.11(b).
 
     6.12. FEES AND EXPENSES. Except as otherwise provided herein and in Section
9.10, each of the parties hereto shall bear its own costs and expenses
(including, without limitation, fees and disbursements of its counsel,
accountants and other financial, legal, accounting or other advisors), incurred
by it or its Affiliates in connection with the preparation, negotiation,
execution, delivery and performance of this Agreement and each of the other
documents and instruments executed in connection with or contemplated by this
Agreement and the consummation of the transactions contemplated hereby and
thereby (collectively, the "Acquisition Expenses"); provided, however, that the
Acquisition Expenses of the Westin Companies (including, without limitation, the
cost of all third party consents to be obtained by the Westin Companies (it
being understood and agreed that the Starwood Companies shall have the right to
approve the incurrence of such expenses prior to such incurrence) and all taxes
(including transfer, recording or similar fees and all income taxes payable by
the Westin Companies and their Subsidiaries directly resulting from the
reorganizations contemplated by
 
                                       40
<PAGE>   44
 
Section 6.17) payable in connection with any transactions or restructurings
contemplated by this Agreement to take place on or prior to the Closing Date,
the fees and expenses of Arthur Andersen & Co. incurred by the Westin
Subsidiaries related to the preparation of the Proxy Statement and the delivery
of the "comfort letter" described in Section 6.5(b) and the fees and expenses
incurred in connection with earnings and profits, valuation and similar due
diligence evaluations, investigations or studies) shall be borne entirely by the
Starwood Companies, and provided further that the Members shall bear the
Acquisition Expenses attributable to the fees and expenses of the financial and
legal advisors to the Members and the Westin Companies incurred in connection
with the transactions contemplated by this Agreement.
 
     6.13. TAKEOVER STATUTE. If any Takeover Statute is or may become applicable
to the Merger or the other transactions contemplated by this Agreement, each of
Starwood Trust and Starwood Corp. and its Board of Trustees or Board of
Directors, as the case may be, shall grant such approvals and take such actions
as are necessary so that such transactions may be consummated as promptly as
practicable on the terms contemplated by this Agreement or by the Merger and
otherwise act to eliminate or minimize the effects of such statute or regulation
on such transactions.
 
     6.14. STARWOOD TRUST AND STARWOOD CORP. VOTE. Starwood Trust and Starwood
Corp. shall cause to be voted (or a consent to be given with respect to) any
Starwood Trust Shares or Starwood Corp. Shares beneficially owned by it or any
of its Affiliates or with respect to which it or any of its Affiliates has the
power (by agreement, proxy or otherwise) to cause to be voted (or to provide a
consent), in favor of the adoption and approval of this Agreement and of the
Merger at any meeting of stockholders of Starwood Trust or Starwood Corp. at
which this Agreement shall be submitted for adoption and approval and at all
adjournments or postponements thereof (or, if applicable, by any action of
stockholders of Starwood Trust or Starwood Corp. by consent in lieu of a
meeting).
 
     6.15. NAME AND MANAGEMENT OF STARWOOD CORP. AND STARWOOD TRUST. Immediately
after the Effective Time, the certificate of incorporation and the by-laws of
Starwood Corp. shall be amended to change the name of Starwood Corp. to "Westin
Hotels & Resorts Worldwide, Inc." Starwood Trust shall include Stuart M.
Rothenberg (and successors to such person as shall be designated by The Goldman
Sachs Group, L.P. ("GS Group") or an affiliate thereof designated by GS Group
("Goldman Sachs")) on each management slate of nominees to the board of trustees
of Starwood Trust. Starwood Corp. shall include Barry S. Volpert (and successors
to such person as shall be designated by Goldman Sachs) and Juergen Bartels (to
the extent he continues as Chief Executive Officer) on each management slate of
nominees to the board of directors of Starwood Corp. Any person so designated by
Goldman Sachs shall be subject to the approval of the Starwood Companies, which
approval shall not be unreasonably withheld; in the event the Starwood Companies
disapprove any such person, Goldman Sachs shall then have the right to designate
another person for approval by the Starwood Companies. The right to designate a
director of Starwood Corp. will expire if Affiliates of Goldman Sachs sell (to
unaffiliated Persons) more than 50% of the Starwood Securities received by
Affiliates of Goldman Sachs in the transactions contemplated by this Agreement
(or Starwood Securities that may be received upon exchange thereof), and the
right to designate a trustee of Starwood Trust will expire if Affiliates of
Goldman Sachs sell (to unaffiliated Persons) more than 75% of the Starwood
Securities received by Affiliates of Goldman Sachs in the transactions
contemplated by this Agreement (or Starwood Securities that may be received upon
exchange thereof). At any time after the Closing Date, if WHWE, Whitehall Street
Limited Partnership V or Goldman Sachs Capital Partners, L.P. defaults in any
payment obligation or materially breaches any of its other agreements, covenants
or obligations under this Agreement or the Other Agreement (as defined in
Section 7.2(k)), and such default or breach continues for 30 days after notice
by the Starwood Companies to Goldman Sachs, then Goldman Sachs's right to
designate individuals to management's slate of nominees under this Section 6.15
shall immediately terminate and Goldman Sachs shall cause its then existing
designees to resign, in each case for so long as such default continues. In the
event the B EPS is exchanged, directly or indirectly, into A EPS or Paired
Shares, this paragraph shall apply with respect to the A EPS or Paired Shares
received upon such exchange, with the A EPS or Paired Shares, as applicable,
received upon exchange of the Purchaser Securities received in the transactions
contemplated by this Agreement that is being deemed to be the last sold. The
management of Starwood Trust and Starwood Corp. after the Effective Time will be
determined in accordance with Article III of this Agreement.

     6.16. ADDITIONAL COVENANTS.
 
     (a) Starwood Trust hereby agrees that, from and after the Closing Date,
Starwood Trust will unconditionally guarantee all indebtedness incurred by any
Member in connection with the transactions contemplated hereby pursuant to a
guarantee reasonably acceptable to the Westin Companies and to the Members.
 
     (b) The Starwood Companies will permit each of the Members (or their
permitted transferees) to guarantee all indebtedness incurred by such Members
(or their permitted transferees) in connection with the transactions
contemplated by this Agreement that is assumed by Starwood Realty Partnership or
Starwood Operating Partnership, as applicable, in connection with the Subsidiary
Contributions (it being understood and agreed that such Members (and their
permitted transferees) will not guarantee any such indebtedness originally
incurred by the Westin Subsidiaries or any subsidiaries of the Westin
Subsidiaries), and, in the event that Starwood Trust is required to make any
payment in respect of its guarantee of such indebtedness described in clause (a)
above and the Members elect to guarantee indebtedness pursuant to this clause
(b), the Members (or their permitted transferees) will pay to Starwood Trust
their proportionate share (based on the proportion that the amount of
indebtedness incurred by such Members (or their permitted transferees) and
assumed by Starwood Realty Partnership or Starwood Operating Partnership bears
to the total amount of indebtedness incurred by all the Members (or their
permitted transferees)) of the amount of any such payment made by Starwood Trust
in respect of such guarantee. The Members (or their permitted transferees) may
at any time, at their option, terminate all or any portion of the guarantees of
indebtedness described in the previous sentence; in the event the Members (or
their permitted transferees) terminate such guarantee or any portion thereof,
(i) Starwood Trust may terminate its guarantee of the portion of such
indebtedness as to which such Member or Members (or their transferees)
terminated its or their guarantee, (ii) the portion of the indebtedness as to
which the guarantee of the Members (or their permitted transferees) has been so
terminated shall no longer be subject to Section 6.16(c), (iii) the amount of
indebtedness of Starwood Realty Partnership or Starwood Operating Partnership
required to be outstanding pursuant to Section 6.16(d)(i) shall be decreased by
the amount of Indebtedness as to which such guarantee has been terminated and
(iv) in the event that each of WHWE, Woodstar and Nomura (or their permitted
transferees) terminates 80% (by dollar amount) or more of its respective
guarantee, the obligations of Starwood Trust, Starwood Realty Partnership and
Starwood Operating Partnership set forth in this Section 6.16(b) and Sections
6.16(a), 6.16(c) (other than the last sentence thereof) and 6.16(d) shall
terminate as of the date of such termination of such guarantees.
 
     (c) Starwood Trust agrees that, in the event the Members exercise their
option to guarantee indebtedness pursuant to clause (b) of this Section 6.16,
during the period beginning on the Closing Date and ending on the date that is
two years after the Closing Date, none of Starwood Trust, Starwood Realty
Partnership, Starwood Operating Partnership, the Westin Subsidiaries contributed
to Starwood Realty Partnership or Starwood Operating Partnership, or any of
their respective Subsidiaries, will repay or refinance any of the indebtedness
assumed by Starwood Realty Partnership or Starwood Operating Partnership in
connection with the Subsidiary Contributions. In the event that after such
two-year period, any such indebtedness of the Starwood Realty Partnership is
repaid or refinanced, the Starwood Realty Partnership will permit the Members to
guarantee indebtedness of the Starwood Realty Partnership having the same
principal amount as such indebtedness so repaid or refinanced by the Starwood
Realty Partnership and, in the event that after such two-year period, any such
indebtedness of the Starwood Operating Partnership is repaid or refinanced the
Starwood Operating Partnership will permit the Members to guarantee indebtedness
of the Starwood Operating Partnership having the same principal amount as such
indebtedness so repaid or refinanced by the Starwood Operating Partnership.
Starwood Trust agrees that for a period of six and one-half months after the
Closing Date it will not repay or refinance, or permit to be repaid or
refinanced, $160 million of the indebtedness of Worldwide and $34,200,000 of
indebtedness of Atlanta permitted to be incurred by Worldwide and Atlanta,
respectively, after the date hereof and prior to the Closing Date.
 
     (d) In the event the Members exercise their option to guarantee
indebtedness pursuant to clause (b) of this Section 6.16, during the period
beginning on the Closing Date and ending on the date that is ten years after the
Closing Date, (i) Starwood Realty Partnership and Starwood Operating Partnership
will maintain an
 
                                       42
<PAGE>   46
 
aggregate amount of indebtedness equal to an amount that is no less than the
amount of indebtedness assumed by Starwood Realty Partnership or Starwood
Operating Partnership, as applicable, in connection with the Subsidiary
Contributions (other than any such indebtedness originally incurred by any of
the Westin Subsidiaries or any subsidiary of the Westin Subsidiaries), (ii) none
of Starwood Trust, Starwood Realty Partnership, Starwood Operating Partnership,
the Westin Subsidiaries contributed to Starwood Realty Partnership or Starwood
Operating Partnership, or any of their respective Subsidiaries, will voluntarily
sell, assign, pledge, dispose of or otherwise transfer any of the stock of such
Westin Subsidiaries contributed to Starwood Realty Partnership or Starwood
Operating Partnership in the Subsidiary Contributions or any of the land and
improvements of such Westin Subsidiaries (excluding time shares), except in a
"like-kind" exchange exempt from taxation pursuant to Section 1031 of the Code,
and (iii) each of Starwood Trust, Starwood Operating Partnership and Starwood
Realty Partnership will comply with covenants substantially to the effect set
forth in Schedule 6.16(d); provided, however, that the Starwood Companies shall
not be required to comply with the covenants contained in this Section 6.16(d)
from and after the date, if any, on which the failure of the Starwood Companies
to comply with such covenants would not adversely affect any of the Members or
the tax position of any of the Members; and provided further, however, that the
Members shall not unreasonably withhold or delay waivers of particular
applications of the covenants set forth in this Section 6.16(d) requested by the
Starwood Companies from time to time so long as such waivers shall not adversely
affect the tax position of any of the Members.
 
     (e) From and after the closing date, each of Starwood Trust, Starwood
Corp., Starwood Realty Partnership and Starwood Operating Partnership shall, no
later than February 28 of each year, deliver to the Members (or their designees)
and each other holder of the stock of a Westin Subsidiary that contributed the
stock of such Westin Subsidiary in a Subsidiary Contribution such accurate
reports and other information as shall be reasonably requested by the Members
(or their designees) for them to file their tax returns for the previous year.
 
     (f) For a period of one year after the Closing Date, the Members will not
sell or otherwise transfer ("Transfer") any of the shares of Class A EPS, Class
B EPS, Starwood Realty Partnership Units or Starwood Operating Partnership Units
received in the transactions contemplated by this Agreement, or any Starwood
Paired Shares received upon conversion or exchange of any thereof (collectively,
"Starwood Securities"), to any Person; provided, however, that any of the
Members may Transfer any of the Class A EPS or Class B EPS received in the
transactions contemplated by this Agreement, or any Starwood Paired Shares
received upon conversion or exchange of any thereof, to one or more investors in
such Member or one or more designees of such investors to whom Starwood
Securities are transferred or issued as contemplated by Section 1.3(g)
("Permitted Designees"), which investors or Permitted Designees have agreed in
writing to comply with the restrictions on Transfer set forth in this paragraph
(f) as though they were Members. From and after the first anniversary of the
Closing Date, none of the Members (or their permitted transferees) or any other
holder of Starwood Realty Partnership Units or Starwood Operating Partnership
Units shall Transfer any Starwood Realty Partnership Units or Starwood Operating
Partnership Units received in the transactions contemplated by this Agreement to
any Person without the prior written consent of the Starwood Realty Partnership
or the Starwood Operating Partnership, as applicable; provided, however, that
this sentence shall not prevent any exchange of any Starwood Realty Partnership
Units or Starwood Operating Partnership Units received in the transactions
contemplated by this Agreement for other Starwood Securities or the Transfer of
any Starwood Securities received upon exchange of Starwood Realty Partnership
Units or Starwood Operating Partnership Units received in the transactions
contemplated by this Agreement. During each of the first four calendar quarters
ending on or after the first anniversary of the Closing Date, no Member will
Transfer more than 25% of the Starwood Securities received by it in the
transactions contemplated by this Agreement, or any Paired Shares received upon
exchange of any Starwood Securities received in the transactions contemplated by
this Agreement, to any Person other than an investor in such Member or one or
more Permitted Designees of such investors; provided, however, that in the event
that less than 25% of such Starwood Securities received by any Member (or an
investor in a Member or a Permitted Designee) are Transferred in any quarter to
any Person other than to the investors in such Member or one or more Permitted
Designees of such investors, the other Starwood Securities held by such Member,
investor or Permitted Designee that could have been Transferred in such quarter
may be Transferred by such Member (or such investor or Permitted Designee) in a
 
                                       43
<PAGE>   47
 
subsequent quarter and the Transfer of such Starwood Securities shall not reduce
the amount of Starwood Securities that could otherwise be Transferred by such
Member (or such investor or Permitted Designee) in such subsequent quarter; and
provided further that this sentence shall not permit a Transfer of Starwood
Realty Partnership Units or Starwood Operating Partnership Units that would be
prohibited by the second sentence of this Section 6.16(f). In the event that a
Member Transfers any of the Starwood Securities to investors in such Member or
to one or more Permitted Designees, such Transfers will be conditioned on the
receipt by such Member of a written agreement of such transferees to be bound by
the provisions of this Section 6.16(f) and Section 6.16(g). Notwithstanding
anything contained herein to the contrary, in the event of a Change in Control
(as defined in the Starwood LTIP) the restrictions on transfer of the Starwood
Securities provided in this paragraph (f)(other than in the second sentence
hereof) shall no longer apply.
 
     (g) Each of the Members agrees that it will not Transfer any of the
Starwood Securities in violation of the registration requirements of the
Securities Act of 1933, as amended, or in such a manner as to cause Starwood
Realty Partnership or Starwood Operating Partnership to be a "publicly traded
partnership" for purposes of the Code.
 
     6.17. REORGANIZATION OF THE PURCHASED ENTITIES. Immediately prior to the
Closing Date, the LLC shall cause the Westin Companies, and shall use all
reasonable efforts to cause the Joint Venture Affiliates, to be reorganized such
that, in the opinion of counsel to the Starwood Companies, the acquisition
contemplated hereby will not adversely affect the ability of Starwood Trust to
qualify as a "real estate investment trust" as defined in Section 856 of the
Code and/or for the purposes of minimizing the number of required consents or
approvals in connection with the transactions contemplated hereby. Such
reorganization shall include such mergers and sales of the Subsidiaries of the
Westin Subsidiaries or assets thereof as shall be necessary or appropriate to
accomplish the foregoing. The preceding sentence notwithstanding, the purchaser
of any assets or the stock of any Subsidiaries of the Westin Subsidiaries to be
sold shall be either a Starwood Company or a subsidiary thereof or a Westin
Subsidiary or a subsidiary thereof. If Worldwide is dissolved or merged into
another corporation as a result of this reorganization, then references in this
Agreement to Worldwide shall be deemed to be references to the
successor-in-interest to Worldwide.
 
     6.18. CLOSING AFTER JANUARY 2, 1998. In the event the Starwood Companies
advise the Westin Companies that the Closing is likely to be delayed beyond
January 2, 1998, the LLC, the Members and the Westin Subsidiaries each agree to
take whatever actions may be reasonably requested by the Starwood Companies to
reorganize and restructure the businesses and assets of the Westin Companies so
as to preserve, to the extent practicable, the tax benefits to the Starwood
Companies that would have accrued had the Closing occurred on January 2, 1998,
and to minimize, to the extent practicable, any tax detriment to the Starwood
Companies that might occur due to the Closing occurring after January 2, 1998
(including by transferring assets among the Westin Subsidiaries and/or by
leasing assets to one or more of the Starwood Companies); provided, however,
that the Starwood Companies shall pay all expenses and costs (including any
incremental Taxes and legal and accounting fees and expenses) actually incurred
by the LLC, the Members and the Westin Subsidiaries in connection with such
reorganization and restructuring and, in the event this Agreement is terminated
in connection with the unwinding of such reorganization and restructuring.
 
     6.19. COMMITMENTS FOR TITLE INSURANCE. The Westin Companies shall deliver
to the Starwood Companies not less than ten days prior to the Effective Date,
with respect to each parcel of real property identified in clause (i) of Section
5.1(p) of the Westin Disclosure Letter and each parcel of Leased Property
identified in clause (ii) of Section 5.1(p) of the Westin Disclosure Letter
(with the exception of immaterial office leases comprising part of the Tenant
Leases), (i) a survey, acceptable to the title company referred to in the last
sentence of this Section 6.19, of a recent date with respect to each such parcel
showing no encroachments or other survey defects with respect to the buildings,
structures and other improvements located on such property; and (ii) a current
commitment for the issuance of an owner's title insurance policy or leasehold
owner's title insurance policy, as the case may be, all of which policies shall
be 1990 form policies with an endorsement deleting the "creditor's rights"
exception or exclusion, with extended coverage insuring over all general
exceptions customarily contained in such policies, including without limitation
general exceptions 1 (rights or claims of parties in possession), 2 (survey
matters), 3 (easements), 4 (mechanic's liens) and 5 (taxes or special
assessments not shown as existing liens), with a Form 3.1 Zoning endorsement
(including
 
                                       44
<PAGE>   48
 
parking and loading docks), survey endorsements insuring that the real property
described in the title insurance policy is the same real estate as shown on the
survey and that the survey accurately depicts the location and dimensions of the
real estate, access endorsement insuring that each street adjacent to the real
property is a public street and that there is direct and unencumbered pedestrian
and vehicular access to such street from the real property, contiguity
endorsement (if the real property consists of more than one record parcel)
insuring that all record parcels are contiguous to one another, location
endorsement identifying the improvements located on the real property, owner's
comprehensive endorsement insuring that there are no encroachments of
improvements onto adjoining land and no violations of enforceable covenants,
conditions or restrictions of record or building lines (and also insuring
against any loss of the right to maintain the improvements located on the real
property because of any such encroachments or current or future violations), and
a non-imputation endorsement insuring against loss due to undisclosed knowledge
of the Westin Companies imputed to the Starwood Companies. Each of such
commitments shall be written by a nationally recognized title insurance company
in amount, form and substance satisfactory to the Starwood Companies and shall
provide that, upon the satisfaction of the conditions specified therein, the
Starwood Companies will have good and marketable title thereto (including all
appurtenant easements), free and clear of all Liens, except for Permitted Liens.
 
     6.20. LIQUOR AND OTHER LICENSES. The Westin Companies shall cooperate, and
prior to the Closing Date shall cause the Westin Companies and their
Subsidiaries, and shall use their reasonable best efforts to cause Westin
O'Hare, to cooperate, with the Starwood Companies in any lawful manner
reasonably requested by the Starwood Companies in connection with obtaining the
regulatory approvals of the transactions contemplated by this Agreement as may
be required by any public agencies administering laws regulating the sale of
alcoholic beverages, including but not limited to, obtaining, by transfer or
otherwise, such approvals for, and/or the issuance of all liquor, cabaret and
other federal, state and local licenses necessary to maintain continuity of
service of alcoholic beverages, as well as the continuity of the same forms of
business operations conducted at, in or upon each property by the Westin
Companies and their Subsidiaries, Westin O'Hare and all other Hotels which are
subject to Hotel Agreements, immediately before the Closing Date. If any such
regulatory approval or license issuance shall not be obtainable by the Starwood
Companies prior to the Closing Date, the Members and the LLC shall, after the
Closing Date, cooperate, and prior to the Closing Date, shall cause the Westin
Companies and their Subsidiaries, and shall use their reasonable best efforts to
cause Westin O'Hare, to cooperate, with the Starwood Companies, at the Starwood
Companies' sole expense, in any lawful and reasonable measure to maintain
continuity of the liquor service as well as the continuity of the same forms of
business operations conducted at, in or upon each property by the Westin
Companies and their Subsidiaries immediately before the Closing Date. Nothing
herein shall require any holder of any liquor, cabaret or other federal, state
or local license to permit any unlicensed Person to unlawfully exercise any
privilege under such license or to have any unlawful interest in liquor
inventory or in revenues from any business operated under such license. The
duties to cooperate set forth herein above shall include, without limitation,
the execution of documents and the renewal of any license or permit issued by
any Governmental Entity.
 
     6.21. SOLICITATION OF EMPLOYEES. Each of the Members and the LLC agrees
that, during the period beginning on the Closing Date and ending on the second
anniversary of the Closing Date, neither it, nor any of its Affiliates (which
such Member unilaterally controls), will, directly or indirectly, solicit
employment, consulting or other services of any employees of the Starwood
Entities, the Westin Subsidiaries or any of their subsidiaries or otherwise
induce such employees to leave the employment of the Starwood Entities, the
Westin Subsidiaries or any of their subsidiaries or breach his or her employment
agreement, if any, with the Starwood Entities, the Westin Subsidiaries or any of
their subsidiaries.
 
     6.22. CONFIDENTIALITY. (a) The Members and the LLC consent and agree not
to, and not to permit their Affiliates to, disclose, communicate, use to the
detriment of any of the Westin Subsidiaries or any of their subsidiaries or
Joint Venture Affiliates, or for the benefit of any other Person, or misuse in
any way, any confidential information or trade secrets of the Purchased
Entities, including, without limitation, the terms, duration and expiration date
of any Hotel Agreement. Nothing in this Section 6.22 shall restrict the Members
and the LLC from disclosing any information that (i) becomes part of the public
domain through no fault of the Members, the LLC or any of their Affiliates or
(ii) is required to be disclosed by law or court order.
 
                                       45
<PAGE>   49
 
     (b) Remedies. The Members and the LLC acknowledge and agree that damages
would not adequately compensate the Starwood Companies if the Members, the LLC
or any of their Affiliates were to breach any of their covenants contained in
Sections 6.21 and 6.22. Consequently, the Members and LLC shall be entitled, in
addition to any other remedies available at law or in equity, to specifically
enforce the terms of Section 6.21 or 6.22 by means of injunction or other
equitable relief.
 
     (c) Validity and Reformation. Should any term or provision of this Section
6.22 be held invalid, unenforceable or illegal by a final adjudication of any
court having competent jurisdiction, or be or become invalidated by reason of
any applicable law or statute existing now or in the future, (i) such term or
provision shall be reformed to reflect the parties' intent and to be enforceable
to the maximum extent permissible under applicable law and (ii) the validity or
enforceability of the remainder of this Section 6.22 shall not be affected
thereby and shall remain in full force and effect.
 
     6.23. CAPITALIZED LEASE OBLIGATIONS. None of the Westin Companies shall
prior to the Effective Date terminate any capitalized lease obligation prior to
its scheduled expiration date.
 
     6.24. FURTHER ASSURANCES. From time to time after the Effective Time, the
officers and director of the Surviving Trust shall be authorized to execute and
deliver, in the name and on behalf of the Westin Subsidiaries and their
respective Subsidiaries or otherwise, such deeds and other instruments and to
take or cause to be taken such further or other action as shall be necessary or
desirable in order to vest or perfect in or to confirm, of record or otherwise,
in the Surviving Trust title to, and possession of, all the property, rights,
privileges, powers, immunities and franchises of the Westin Companies and
otherwise carry out the purposes of this Agreement. With respect to any license,
certificate, approval, authorization, agreement, contract, lease, easement and
other commitment included in the Westin Companies' assets which requires the
consent of any third Person to the Merger or any other transaction contemplated
hereby, if any such consent has not been obtained prior to the Effective Time,
thereafter the LLC and each of the Members shall cooperate with the Surviving
Trust and Starwood Corp. at their request in endeavoring to obtain such consent
promptly, and if any such consent is unobtainable, to use all reasonable efforts
to secure to the Surviving Trust and Starwood Corp. the benefits thereof in some
other manner; provided, however, that nothing herein shall relieve any of the
LLC or the Members of their respective obligations under Section 6.5.
 
     6.25. TRANSFER OF CERTAIN RIGHTS OF LLC. At the Closing, the LLC shall
transfer, assign and convey any and all rights and interests to which it is
entitled to under the Amended and Restated Stock Purchase Agreement, dated as of
May 12, 1995, among Westin Hotel Holding Corp., Westin Hotel L.L.C., Ceasar Park
Hotel Investment, Inc. and Aoki Corporation, and any other agreements entered
into in connection therewith (collectively, the "Aoki Agreement"), to the
Starwood Companies; provided, however, that to the extent that any such
transfer, assignment or conveyance would constitute a breach of the Aoki
Agreement, this Agreement (and any related documents delivered at the Closing)
shall not constitute an actual or attempted transfer, assignment or conveyance
of the Aoki Agreement unless and until the consent or waiver of such breach is
obtained from the parties to the Aoki Agreement other than the Westin Companies.
To the extent that the consents and waivers referred to in the proviso to the
immediately preceding sentence are not obtained prior to the Closing, (x) each
Member and the LLC shall use all reasonable efforts to (A) provide or cause to
be provided to the Starwood Companies the benefits of the Aoki Agreement, (B)
cooperate in any arrangement, reasonable and lawful as to both the Members and
the LLC and the Starwood Companies, designed to provide such benefits to the
Starwood Companies and (C) enforce for the account of the Starwood Companies any
rights of the Members and the LLC arising from the Aoki Agreement, including all
rights to payments and to indemnification, in each case after consulting with
and upon the advice and direction of the Starwood Companies. In connection with
the foregoing, the Members and the LLC agree to make their personnel, and
applicable books and records, reasonably available to the Starwood Companies (at
no cost to the Starwood Companies) in order to effect all actions reasonably
required to be taken under this Section 6.26. The Starwood Companies agree to
reimburse the Members and the LLC for all reasonable out-of-pocket expenses
incurred by them in connection with the foregoing.
 
     6.26. NOMURA CONSENTS. Nomura hereby agrees to provide the consents to the
transactions contemplated by this Agreement described in Section 7.2(l).
 
                                       46
<PAGE>   50
 
     6.27. ESCROW ARRANGEMENT. The Members and the LLC shall use all reasonable
efforts to establish, on or prior to the Closing Date, the escrow arrangement
contemplated by Section 7.2(k).
 
     6.28. ADDITIONAL AGREEMENTS WITH NOMURA. On or prior to March 28, 1998,
Nomura will not securitize indebtedness held by it relating to Denver (with an
aggregate principal amount of $45 million plus $8.5 million of preferred equity)
or to St. John (currently with an aggregate principal amount of $20 million) and
will allow the Starwood Companies to prepay all of such indebtedness (and
preferred equity) plus all breakage costs relating to any related U.S. Treasury
hedge positions (it being understood that Nomura will use its best efforts to
minimize such costs, including, but without limitation, "rolling" such hedge
positions into the new loans referred to below), but otherwise without premium
or penalty, on or prior to March 29, 1998. Concurrently therewith, Starwood
Trust will borrow from Nomura no less than $67.6 million principal amount of
indebtedness secured by one or more first mortgages (the underlying property of
which, in Nomura's reasonable judgment, is promptly capable of supporting an
optimal securitization of such indebtedness with a structure and pursuant to
documentation which is usual and customary for securitizations by Nomura and
which satisfy rating agency standards) on comparable quality assets as Denver
and St. John and on terms that will provide Nomura with comparable pricing,
fees, debt service coverage, collateralization, amortization and other economic
terms, in the aggregate, as Nomura would have received had the indebtedness of
Denver and St. John been securitized by Nomura instead of being prepaid.
 
     The contemplated loans on Atlanta aggregating up to $34.2 million will not
be secured by any lien or encumbrance on the equity interests in Westin Portman
Peachtree II L.L.C. On the Closing Date, the $15 million of related credit
enhancement from the Members for capital improvements over three years will
become credit enhancement (on the same terms and conditions) from Starwood
Corporation and the Starwood Operating Partnership and the Members will be
released by Nomura and its affiliates from any obligation on such credit
enhancement after such date. Securitization of the indebtedness related to
Atlanta may proceed as planned by Nomura.

Effective Time by the Westin Companies or the Starwood Companies or any of their
respective Subsidiaries from, any Governmental Entity (collectively,
"Governmental Consents") in connection with the execution and delivery of this
Agreement and the consummation of the Merger and the other transactions
contemplated hereby by the Westin Companies and the Starwood Companies shall
have been made or obtained (as the case may be), except those the failure to
make or to obtain are not, individually or in the aggregate, reasonably likely
to have a Westin Material Adverse Effect or a Starwood Material Adverse Effect
or to provide a
 
                                       47
<PAGE>   51
 
reasonable basis to conclude that the parties hereto or any of their affiliates

enjoins or otherwise prohibits consummation of the Merger or the other
transactions contemplated hereby (collectively, an "Order"), and no Governmental
Entity shall have instituted any proceeding therefor.
 
     7.2. CONDITIONS TO OBLIGATIONS OF THE STARWOOD COMPANIES. The obligations
of the Starwood Companies to effect the Merger and the other transactions
contemplated hereby are also subject to the satisfaction or waiver by the
Starwood Companies at or prior to the Effective Time of the following
conditions:
 
     (a) Representations and Warranties. The representations and warranties of
the Westin Companies set forth in this Agreement shall be true and correct in
all material respects as of the date of this Agreement and as of the Closing
Date as though made on and as of the Closing Date (except to the extent any such
representation and warranty expressly speaks as of an earlier date and except to

shall speak as of the date the last revisions to the Westin Disclosure Letter
are furnished to the Starwood Companies)), and the Starwood Companies shall have
received a certificate to such effect signed on behalf of the Westin Companies
by the chief financial officer and secretary of Worldwide provided, however,
that notwithstanding anything herein contained to the contrary, this Section
7.2(a) shall be deemed to have been satisfied even if (i) such representations
or warranties were not true and correct on the date of this Agreement but are so
true and correct on the Closing Date or (ii) any such representation or warranty
(other than the representations and warranties contained in Section 5.1(a),
5.1(b), 5.1(c), 5.1(e), 5.1(o), 5.1(t) and 5.1(u)) is untrue as written but such
representation or warranty would be true if any or all of the documents listed
on Schedule 7.2(a) hereof and the contents thereof (other than any documents
referenced in any such documents that are not themselves also listed on Schedule
7.2(a) hereof) were incorporated as exceptions to such representation and
warranty.
 
     (b) Performance of Obligations of the Westin Companies. The Westin
Companies shall have performed in all material respects all material obligations

transaction contemplated in Section 6.1(b)(iv)(d), the Starwood Companies shall
have received the opinion of Sidley & Austin, special counsel to the Starwood
Companies, subject to assumptions reasonably acceptable to the Westin Companies,
to the effect that (A) the Merger will constitute a "reorganization" with the
meaning of Section 368(a) of the Code and (B) Starwood Trust will continue to
qualify as a REIT for U.S. federal income tax purposes after consummation of the
transactions contemplated by this Agreement.
 
     (ii) The Starwood Companies shall have received the opinion of Sidley &
Austin, special counsel to the Starwood Companies, dated the Closing Date, in
substantially the form attached hereto as Annex E-1, which opinion shall restate
as of the Closing Date the opinion described in Section 7.2(c)(i).
 
     (iii) Starwood Trust shall have received an opinion of Sullivan & Cromwell,
special counsel to the Westin Companies, dated the Closing Date, substantially
in the form attached hereto as Annex E-3.
 
     (d) Accountants Letter. The Starwood Companies shall have received from
Arthur Andersen LLP the "comfort letter" described in Section 6.5(b).
 
     (e) Fairness Opinion. The Special Committee of Disinterested Trustees of
the Board of Trustees of Starwood Trust and the Special Committee of
Disinterested Directors of the Board of Directors of Starwood Corp. shall have
received an opinion of Morgan Stanley & Co. Incorporated, in a form satisfactory
to each
 
                                       48
<PAGE>   52
 
board, to the effect that the Merger, the Subsidiary Contributions and the other
transaction contemplated by this Agreement are fair, from a financial point of
view, to Starwood Trust and Starwood Corp.
 
     (f) Material Adverse Change. There shall not have occurred, since the date
of this Agreement, any material adverse change in the financial condition,
properties, business or results of operations of the Westin Companies and their
Subsidiaries taken as a whole or any development or combination of developments
individually or in the aggregate, that has had or is reasonably likely to have a
Westin Material Adverse Effect.
 
     (g) Change in Tax Laws. There shall not have been any changes in the U.S.
federal income tax laws that materially and adversely affects the ability of
Starwood Trust to consummate the Merger as a "tax-free reorganization" under the
Code or on the ability of Starwood Trust to maintain its status as a REIT for
purposes of the Code.
 
     (h) Financing. There shall have been no change in the general economic,
financial or market conditions in the United States that materially and
adversely affects that ability of the Starwood Companies to obtain the financing
necessary to consummate the transactions contemplated by this Agreement.
 
     (i) FIRPTA Certificate. LLC, each Member and any other person receiving
Starwood Securities or other consideration pursuant to this Agreement shall have
delivered to the Starwood Companies a certification of nonforeign status, in

investors in Joint Venture Affiliates and ground lessors of Hotels (or the
properties on which such Hotels are located) from whom consents, approvals or
authorizations are required to be obtained in connection with the consummation
of the transactions contemplated by this Agreement shall not have delivered
written notices of their intention to terminate such agreements or ground leases
("Termination Notices"); provided that this condition shall be deemed to have
been satisfied unless the projected 1998 management fee and/or franchise fee
and/or other revenues (other than marketing fees (including portions of
management and franchise fees that are allocated to marketing fees) and
reimbursed expenses and other revenue items that do not result in a profit for
the Westin Companies) from all such contracts in respect of which such notices
have been received, equal or exceed, in the aggregate, $8,000,000; provided,
further, that this condition shall be deemed to have been waived by the Starwood
Companies if the Starwood Companies do not elect not to consummate the
transactions contemplated by this Agreement as a result of the failure to
satisfy this condition on or prior to November 25, 1997; provided, however, that
in the event the transaction described on Section 6.1(b)(iv)(a) shall not have
occurred prior to November 25, 1997, the foregoing reference to November 25,
1997 shall be deemed to be a reference to the earlier to occur of (i) the
occurrence of the transaction contemplated by Section 6.1(b)(iv)(a) or (ii) the
date that is fourteen days before the Stockholders' Meeting referred to in
Section 6.4. For purposes of the foregoing sentence, 50% of the projected 1998
management fee and/or franchise fee and/or other revenues with respect to
management, franchise or similar agreements that are subject to the provisions
of the License and Master Assignment Agreement, dated as of May 12, 1995, among
Westin International Asia Pacific Corporation, Aoki Corporation, Westin Hotel
Company and the other parties thereto, shall be included in determining whether
the $8,000,000 threshold in the previous sentence has been equaled or exceeded.
Notwithstanding the foregoing, applicable written consents or approvals (as
distinguished form Termination Notices), including such approvals as are
required for modifications to Joint Venture Agreements and/or the execution of
supplementary agreements reasonably required for the continued ownership of
Joint Venture Affiliates in a manner consistent with the REIT or Paired Share
qualification requirements applicable to the Starwood Companies, shall be
required from such owners, unaffiliated third party investors or ground lessors
(collectively, the "Third Parties"), as applicable, with respect to the assets
identified on Schedule 7.2(j), and the failure to obtain any such consent or
approval from the applicable Third Party shall be deemed to be the delivery by
such Third Party of a Termination Notice for purposes of the first proviso to
the first sentence of this Section 7.2(j).
 
                                       49
<PAGE>   53
 
     (k) Other Agreements. WHWE, Woodstar, Nomura and Bartels shall have
executed and delivered an indemnity agreement in the form agreed to on the date
hereof (the "Other Agreement"), and there shall have been established, on or
prior to the Closing Date, with respect to the matters described in the Other
Agreement, an escrow arrangement relating to the Starwood Securities received by
the stockholders of the Westin Subsidiaries other than WHWE, Woodstar, Nomura
and Bartels, in form and substance reasonably satisfactory to the Starwood
Companies, providing for the same pro rata economic effect with respect to such
stockholders as the Other Agreement provides for WHWE, Woodstar, Nomura and
Bartels.
 
     (l) Nomura Consents. Nomura and Property Acquisition Trust, as the case may
be, shall have consented to the transactions contemplated by this Agreement
under all debt agreements relating to indebtedness of the Joint Venture
Affiliates, Westin Companies and their respective Subsidiaries and under any
joint venture agreements, limited liability agreements or partnership agreements
to which Nomura is a party; provided, however, the foregoing shall not require
Nomura to consent to the assumption by any of the Starwood Companies of the
Subordinated Debt of Westin Hotel Company issued to Nomura pursuant to the
Subordinated Note and Class B Purchase Agreement dated as of May 12, 1995 among
Nomura and certain Westin Companies or the Participation Agreement dated as of
May 12, 1995, among Nomura, the Members, the LLC and the other parties thereto
and nothing herein shall be deemed to be such a consent.
 
     7.3. CONDITIONS TO OBLIGATION OF THE WESTIN COMPANIES. The obligations of

any manner that shall have proximately contributed to the occurrence of the
failure of the Merger to be consummated.

and the Merger and the other transactions contemplated hereby may be abandoned
at any time prior to the Effective Time, whether before or after the approval by

terminated and the Merger and the other transactions contemplated hereby may be
abandoned at any time prior to the Effective Time, whether before or after the
approval by the stockholders of Starwood Corp. or the shareholders of Starwood

Starwood Corp. or the Board of Trustees of Starwood Trust if (i) there has been
a material breach by the Westin Companies of any representation, warranty,
covenant or agreement contained in this Agreement that is not curable or, if
curable, is not cured within 30 days after written notice of such breach is
given by the Starwood Companies to the party committing such breach (provided
that if such 30-day period would but for this proviso extend past January 2,
1998, such period shall be deemed to end on January 2, 1998) or (ii) as
contemplated by the penultimate sentence of Section 9.14(a), in the case of
either (i) or (ii) above, by action to such effect of the Board of Directors of
Starwood Corp. or the Board of Trustees of Starwood Trust.
 
     8.5. EFFECT OF TERMINATION AND ABANDONMENT.
 
     (a) In the event of termination of this Agreement and the abandonment of
the Merger and the other transactions contemplated hereby pursuant to this
Article VIII, this Agreement (other than as set forth in Section 9.1) shall
become void and of no effect with no liability on the part of any party hereto
(or of any of its trustees, directors, officers, employees, agents, legal and
financial advisors or other representatives); provided, however, except as
otherwise provided herein, no such termination shall relieve any party hereto of
any liability or damages resulting from any wilful breach of this Agreement.
 
     (b) In the event that (a) this Agreement is terminated by the Westin
Companies pursuant to Section 8.3, (b) the condition set forth in Section 7.1(a)
shall not have been satisfied and this Agreement shall have been terminated
pursuant to Section 8.2, (c) the Starwood Companies shall have failed to satisfy
any of the conditions set forth in Section 7.3(a), (b), (c)(i), (c)(ii), (d),
(e) or (g) on or prior to the Closing Date and the Westin Companies shall, by
written notice delivered to Starwood Trust, elect not to consummate the
transactions contemplated hereby as a result of such failure or (d) the Starwood
Companies otherwise fail to consummate the transactions contemplated by this
Agreement, then the Starwood Companies shall promptly, but in no event later
than five business days after the date of such event, pay the Westin Companies a
termination fee of $5,000,000 and shall promptly, but in no event later than
five business days after the date of such event, pay all the charges and
expenses incurred by the Westin Companies and the Members in connection with
this Agreement and the transactions contemplated by this Agreement in an amount
not to exceed $5,000,000, in each case payable by wire transfer of same day
funds; provided, however, that no such payment shall be required in the event
that (i) the Westin Companies shall have failed, after the expiration of 30 days
after receipt by the Westin Companies of written notice of such failure during
which the Westin Companies shall have the opportunity to cure any such failure,
provided, that such cure period shall not extend beyond January 2, 1998 unless
the parties shall have agreed to extend the Closing Date to a date that is later
than January 2, 1998 to satisfy any condition specified in Section 7.2 that is
required to be satisfied by the Westin Companies prior to the Closing Date, (ii)
the Starwood Companies elect not to consummate the transactions as a result of
the failure of the satisfaction of the condition specified in Section 7.1(b) or
(c) or 7.2(a), (b), (c)(iii), (d), (f), (g), (i), (j), (k) or (l) or Section
9.14 or (iii) the Starwood Companies fail to deliver the opinions of Sidley &
Austin required to be delivered by Section 7.3(c)(i) or (ii), and the sole cause
of such failure is a change in the factual circumstances of the Westin Companies
occurring after the date hereof that causes one or more explicit assumptions
contained in the opinion attached hereto as Annex E-1 to be untrue as of the
Closing Date. The Starwood Companies' payment shall be the sole and exclusive
remedy of the Westin Companies against the Starwood Companies and any of their
Subsidiaries and their respective directors, officers, employees, agents,
advisors or other representatives with respect to the breach of any covenant or
agreement giving rise to such payment. The Starwood Companies acknowledge that
the agreements contained in this Section 8.5(b) are an integral part of the
transactions contemplated by this Agreement and that, without these agreements,
the Westin Companies would not enter into this Agreement.

provision and (b) the remainder of this Agreement and the application of such
provision to other Persons or circumstances shall not be affected by such
invalidity or unenforceability, nor shall such invalidity or unenforceability
affect the validity or enforceability of such provision, or the application
thereof, in any other jurisdiction.
 
     9.12. INTERPRETATION; CERTAIN DEFINED TERMS.
 
     (a) The table of contents and headings herein are for convenience of
reference only, do not constitute part of this Agreement and shall not be deemed
to limit or otherwise affect any of the provisions hereof. Where a reference in
this Agreement is made to a Section, Annex, Schedule or Exhibit, such reference
shall be to a Section of or Exhibit or Annex to this Agreement unless otherwise
indicated. Whenever the words "include," "includes" or "including" are used in
this Agreement, they shall be deemed to be followed by the words "without
limitation." For purposes of this Agreement, "indebtedness" includes
indebtedness for borrowed money and capitalized lease obligations.
 
     (b) As used in this Agreement, the term (1) "Affiliate" means, with respect
to any Person, any other Person which directly or indirectly controls, is
controlled by or is under common control with such Person, and (2) "Purchased
Entities" means the Westin Subsidiaries and their Subsidiaries and all other
entities of which any of Westin Subsidiaries or any of their Subsidiaries has a
direct ownership interest, including the Joint Venture Affiliates.
 
     9.13. SUCCESSORS AND ASSIGNS. (a) The rights of each party under this
Agreement shall not be assignable by such party prior to the Effective Time
without the written consent of each of the other parties. Following the
Effective Time, any party may assign any of its rights hereunder, but no such
assignment shall relieve it of its obligations hereunder.
 
     (b) This Agreement shall be binding upon and inure to the benefit of the
parties hereto and their successors and permitted assigns. The successors and
permitted assigns hereunder shall include without limitation, in the case of the
Starwood Companies, any permitted assignee as well as the successors in interest
to such permitted assignee (whether by merger, liquidation (including successive
mergers or liquidations) or otherwise). Except as provided in Section 6.11,
nothing in this Agreement, expressed or implied, is intended or shall be
construed to confer upon any Person other than the parties and successors and
assigns permitted by this Section 9.13 any right, remedy or claim under or by
reason of this Agreement.
 
     9.14. DISCLOSURE LETTER UPDATING. (a) The Westin Companies may revise the
Westin Disclosure Letter to reflect any changes that occur after the date hereof
or to reflect matters coming to the attention of the Westin Companies after the
date hereof by delivering a revised Westin Disclosure Letter (or portion
thereof) to the Starwood Companies at any time prior to ten business days prior
to the Closing Date, marked to show changes from the most recent previously
delivered Westin Disclosure Letter (or such portion thereof). The Starwood
Companies shall have the right to review the revised Westin Disclosure Letter
(or such portion thereof) for a period of ten business days after receipt
thereof. If during such ten business-day period the Starwood Companies shall
have made a reasonable determination that the revised information contained in
the Westin Disclosure Letter (or such portion thereof), together, in the case of
the first revision to the Westin Disclosure Letter, with any document referred
to in the Westin Disclosure Letter as of the date hereof which is not listed in
Schedule 7.2(a) (without giving effect to any revision thereof occurring after
the date hereof), would have on the Closing Date caused the condition set forth
in Section 7.2(a) not to have been satisfied, the Starwood Companies shall have
the right to deliver a notice to the Westin Companies during such period to the
effect that the Starwood Companies are electing to terminate this Agreement
pursuant to Section 8.4. If the Starwood Companies do not give such notice
within such period, the Starwood Companies shall be
 
                                       56
<PAGE>   60
 
deemed to have accepted such revisions and/or the inclusion of such additional
documents as a revision to Schedule 7.2(a), and the Westin Disclosure Letter
shall be deemed to be superseded by the revised Westin Disclosure Letter.
 
     (b) The Starwood Companies may revise the Starwood Disclosure Letter to
reflect any changes that occur after the date hereof or to reflect matters
coming to the attention of the Starwood Companies after the date hereof by
delivering a revised Starwood Disclosure Letter (or portion thereof) to the
Westin Companies and the Members at any time prior to ten business days prior to
the Closing Date, marked to show changes from the most recent previously
delivered Starwood Disclosure Letter (or such portion thereof). The Westin
Companies shall have the right to review the revised Starwood Disclosure Letter
(or such portion thereof) for a period of ten business days after receipt
thereof. If during such ten business-day time period the Westin Companies and
the Members shall have made a reasonable determination that the revised
information contained in the Starwood Disclosure Letter (or such portion
thereof) would have on the Closing Date caused the condition set forth in
Section 7.3(a) not to have been satisfied, the Westin Companies shall have the
right to deliver a notice to the Starwood Companies during such period to the
effect that the Westin Companies and the Members are electing to terminate this
Agreement pursuant to Section 8.3. If the Westin Companies and the Members do
not give such notice within such period, the Westin Companies shall be deemed to
have accepted such revisions, and the Starwood Disclosure Letter shall be deemed
to be superseded by the revised Starwood Disclosure Letter.
