            MERISTAR HOTELS & RESORTS TO MERGE WITH INTERSTATE HOTELS

      NEW COMPANY WILL OPERATE MORE THAN 400 HOTELS WITH OVER 86,000 ROOMS

      WASHINGTON, D.C., AND PITTSBURGH, May 2, 2002--MeriStar Hotels & Resorts
(NYSE: MMH) and Interstate Hotels Corporation (Nasdaq: IHCO), the nation's two
largest independent hotel management companies, today announced that they have
signed a definitive agreement to merge.

      The combined company will be the premier independent hotel operator in the
world, operating more than 86,000 rooms in 412 hotels, representing over 30
franchise brands in North America and Europe. The combined company will possess
expansive operational and financial resources enabling it to provide
state-of-the-art services to hotel owners.

      The combined company, to be named Interstate Hotels Corporation, will
include BridgeStreet Corporate Housing Worldwide and Doral Resorts & Conference
Centers. It will have estimated 2002 pro forma revenues of $340 million, and
estimated pro forma EBITDA of $33 million to $35 million. The transaction is
valued at approximately $68 million based on MeriStar's closing stock price of
$1.21 on May 1, resulting in a total market capitalization of $260 million for
the combined company.

      The combined company will be headquartered in Washington, D.C. while
maintaining a significant operating presence in Pittsburgh. Paul W. Whetsell,
MeriStar chairman and chief


                                     - 1 -
<Page>

executive officer, and John Emery, president and chief operating officer, will
continue in those roles for the merged company. Interstate's Chairman and Chief
Executive Officer Thomas F. Hewitt will serve on the combined company's board of
directors. The combined company's board of directors initially will include six
members nominated by MeriStar and seven members nominated by Interstate, of
which five initially will be representatives from Interstate's Investor Group.

      "The merger will create an independent hotel management company with a
portfolio of more than 400 properties in the United States, Canada and Russia,
which will allow us to achieve significant economies of scale," said Whetsell.
"We expect synergistic corporate savings of between $8 million and $10 million
on an annualized basis. The merger will be accretive to stockholders in 2002."

      Commenting on the merger, Hewitt said, "Since our spin-off from Wyndham
International, we have been committed to strengthening the financial structure
of our organization and strategically growing the company. We have
overwhelmingly concluded that this transaction is in the best interests of our
stockholders. We believe the combined company will offer stockholders of both
companies a strong platform for future growth.

      "In addition, we will be a stronger, more efficient operator, allowing us
to generate higher returns for our owners and, as a result, higher management
fees for the new company than we could have achieved operating separately,"
Hewitt said. "Both companies' properties are complementary, and Interstate's
presence in Eastern Europe, combined with MeriStar's BridgeStreet Corporate
Housing Worldwide division's experience in Western Europe, creates additional
growth avenues."

      "Both Interstate and MeriStar have a highly focused emphasis on customer
service and generating the highest possible returns for their owners," Whetsell
said. "Our initial internal


                                     - 2 -
<Page>

mission will be to meld our highly similar operating philosophies into one
common culture and focus on associate retention. We expect the transaction to be
virtually seamless to employees at our hotels."

TRANSACTION HIGHLIGHTS

      In the tax-free, stock-for-stock merger of Interstate into MeriStar,
Interstate stockholders will receive 4.6 shares of the surviving company's
common stock for each share of the 12.2 million shares of Interstate common
stock outstanding and each of the 39.4 million existing shares of MeriStar
common stock and operating partnership units will remain outstanding. All
Interstate stock options will be converted into options to purchase shares of
the combined company.

      The consummation of the merger is subject to various conditions, including
U.S. antitrust clearance and the respective approvals of the stockholders of
Interstate and MeriStar. The stockholders meetings and the closing are expected
to occur in the third quarter of 2002. MeriStar or Interstate may each receive
from the other a termination fee of $2 million plus up to $500,000 in expenses
if the merger agreement is terminated by the other party under various
circumstances.

      In connection with the transaction, Interstate's Investor Group will
convert its Interstate convertible debt and preferred equity into shares of
common stock of the combined company and receive a payment of $9.25 million. The
Investor Group and Interstate senior management have committed to vote in favor
of the merger their Class A common stock, which will constitute approximately 57
percent of Interstate's common stock expected to be outstanding at the time of
the Interstate stockholders meeting. Oak Hill Capital Partners and its
affiliates and MeriStar management, which collectively own 22 percent of
MeriStar common stock, have agreed to vote their shares in favor of the merger.


                                     - 3 -

      The respective boards of directors approved the transaction yesterday. The
Interstate board action was based in part upon the recommendation of its Special
Committee of independent directors. Each board received a fairness opinion from
its respective financial advisor. Salomon Smith Barney advised MeriStar in the
transaction and Merrill Lynch advised Interstate.

GROWTH STRATEGIES AND TRANSACTION BENEFITS

      "Due to economies of scale, a larger customer base, and an improved
capital structure, the merged company will have expanded avenues of growth,"
Emery said. "The new company will have a real estate joint venture in place to
acquire $300 million to $500 million of hotel assets, and up to $50 million of
cash and availability on its line of credit to participate in joint ventures."

      The hotel management business unit will use its expanded resources to
provide current and prospective owners with a wide array of improved services
and benefits, including Internet-based business information systems providing
real-time data for better yield management and cost control; broader electronic
and direct sales resources, including more than 2,000 sales professionals;
increased cost efficiency through national purchasing; and capital for
co-investments and joint ventures.

      BridgeStreet's growth will be gained through expansion of its national
client base and European operations, as well as its recently established
licensing program for North American markets.

      Doral Resorts & Conference Centers will grow through new management
contracts that leverage the strength of the Doral name and a central
reservations system.

CAPITAL STRUCTURE

      A new $113 million senior credit facility will replace the existing
revolving credit


                                     - 4 -
<Page>

facilities of both companies. The facility, for which credit commitments have
been received, will have a three-year term loan and a three-year revolver with a
one-year option to extend. The interest rate on the facility will range from
LIBOR + 300 basis points to LIBOR + 450 basis points, based on certain financial
covenant levels. Total debt outstanding, net of cash, is expected to be $135
million at closing. Emery commented, "The merger significantly improves our
capital structure due to the conversion of Interstate's $25 million of
convertible notes and $7.25 million of convertible preferred stock into shares
of common stock of the combined company prior to closing."

      Upon completion of the merger, the combined company is expected to have
approximately 105 million common shares and operating partnership units
outstanding.

CONFERENCE CALL

      MeriStar and Interstate will hold a joint conference call at 2 p.m. ET
today to discuss in greater detail the merger of the two companies. The
conference call will feature Paul W. Whetsell, chairman and chief executive
officer, MeriStar Hotels & Resorts; Thomas F. Hewitt, chairman and chief
executive officer of Interstate Hotels; and John Emery, president and chief
operating officer of MeriStar Hotels & Resorts. A simultaneous webcast of the
conference call will be available at MeriStar's Web site, www.meristar.com, and
at www.streetevents.com.

      The new company will combine MeriStar's 277 managed hotels with
Interstate's 135 properties, giving it more than twice those of its nearest
competitor in terms of properties and three times the size in number of rooms.
The combined company will be the largest independent operator of full-service

      AGREEMENT AND PLAN OF MERGER (this "AGREEMENT"), dated as of May 1, 2002,
by and between INTERSTATE HOTELS CORPORATION, a Maryland corporation
("INTERSTATE"), and MERISTAR HOTELS & RESORTS, a Delaware corporation
("MERISTAR").

                                    RECITALS

      A. The respective Boards of Directors of MeriStar and Interstate have each
determined that the merger of Interstate with and into MeriStar on the terms and
subject to the conditions set forth in this Agreement, with MeriStar as the
surviving corporation (the "MERGER"), is advisable and that it is in the best
interest of their respective corporations and stockholders to combine the
respective businesses of MeriStar and Interstate, and consequently have approved
and adopted the Merger and this Agreement, in accordance with, as to MeriStar,
the General Corporation Law of the State of Delaware (the "DGCL") and, as to
Interstate, the Maryland General Corporation Law (the "MGCL").

      B. Concurrently with the execution of this Agreement, (i) as a condition
to the willingness of Interstate to enter into this Agreement, the executive
officers and certain directors of MeriStar (the "PRINCIPAL MERISTAR MANAGERS")
and certain holders of MeriStar Common Stock (the "PRINCIPAL MERISTAR
STOCKHOLDERS") are entering into a voting agreement, dated the date hereof (the
"MERISTAR VOTING AGREEMENT"), which provides, among other things, that each
Principal MeriStar Manager and each Principal MeriStar Stockholder party thereto
will vote his or her shares of MeriStar Common Stock in favor of the MeriStar
Proposals at the MeriStar Stockholders Meeting; and (ii) as a condition to the
willingness of MeriStar to enter into this Agreement, certain holders of
Interstate Common Stock (the "PRINCIPAL INTERSTATE STOCKHOLDERS") are entering
into a voting agreement, dated the date hereof (the "INTERSTATE VOTING
AGREEMENT"), which provides, among other things, that (a) each Principal
Interstate Stockholder will vote his or her shares of Interstate Common Stock in
favor of the Interstate Proposals at the Interstate Stockholders Meeting, (b) a
portion of the Interstate Convertible Securities held by each Principal
Interstate Stockholder will be converted, on or immediately prior to the record

into shares of Interstate Common Stock, and (c) the holders of Interstate
Convertible Securities representing a majority of the combined (x) aggregate
principal amount of Interstate Convertible Notes outstanding and (y) aggregate
stated amount of the Interstate Series B Preferred Stock outstanding on the
record date for such vote of such holders, in each case, excluding Interstate
Convertible Securities held by Interstate or any of its executive officers, will
vote in favor of the Interstate Proposals.

      C. For federal income tax purposes it is intended that the Merger shall
qualify as a reorganization under the provisions of Section 368(a) of the
Internal Revenue Code of 1986, as amended (the "CODE"), and the rules and
regulations promulgated under the Code.

      D. Certain terms used in this Agreement have the meanings specified in
Section 8.1.

      NOW, THEREFORE, in consideration of the mutual representations, warranties
and agreements contained herein, and for other good and valuable consideration
the receipt and sufficiency of which are hereby acknowledged, the parties to

and Continental Stock Transfer Trust Company (as amended, the "MERISTAR RIGHTS
AGREEMENT") (the "MERGER CONSIDERATION");

            (b) At the Effective Time, all Interstate Common Stock shall no
longer be outstanding, shall be canceled and retired and shall cease to
exist, and each instrument or certificate (a "CERTIFICATE") formerly
representing any Interstate Common Stock (other than shares of Interstate
Common Stock owned by Interstate or by MeriStar, any MeriStar Subsidiary or
any Interstate Subsidiary) shall thereafter represent only the right to
receive the Merger Consideration and any distribution or dividend thereon
pursuant to Section 2.2(c), in each case, without interest.

            (c) At the Effective Time, each share of MeriStar Common Stock,
including the associated MeriStar Right, issued and outstanding immediately
prior to the Effective Time, shall remain issued and outstanding and shall
continue to represent one validly issued, fully paid and nonassessable share of
the Surviving Corporation Common Stock and one associated MeriStar Right.

            (d) At the Effective Time, each of the Interstate Convertible
Securities issued and outstanding immediately prior to the Effective Time, shall
remain issued and outstanding and shall be deemed to be a convertible
security of the Surviving Corporation.

      Section 2.4 EXCHANGE OF CERTIFICATES.

            (a) EXCHANGE AGENT. As of the Effective Time, the Surviving
Corporation shall deposit with the transfer agent for shares of the Surviving
Corporation Common Stock, or with such other bank or trust company designated by
the Surviving Corporation prior to the Effective Time and reasonably acceptable
to Interstate (the "EXCHANGE AGENT"), for the benefit of the holders of
Certificates, for exchange in accordance with this Article II through the
Exchange Agent, certificates representing the number of shares of Surviving
Corporation Common Stock (such shares of Surviving Corporation Common Stock,
together with any dividends or distributions with respect thereto to which the
holders of Certificates may be entitled pursuant to Section 2.2(c) hereof being
hereinafter referred to as the "EXCHANGE FUND") issuable pursuant to Section
2.1(b) hereof in exchange for outstanding shares of Interstate Common Stock.

            (b) EXCHANGE PROCEDURES. Promptly after the Effective Time, the
Surviving Corporation shall cause the Exchange Agent to mail to each holder of
record of a Certificate (other than MeriStar, any MeriStar Subsidiary or any
Interstate Subsidiary) (i) a letter of transmittal specifying that delivery
shall be effected, and that risk of loss and title to the Certificates shall
pass, only upon delivery of the Certificates (or affidavits of loss in lieu of
Certificates) to the Exchange Agent, in a form and with other customary
provisions reasonably


                                       4
<Page>

specified by Interstate, and (ii) instructions for surrendering the Certificates
in exchange for (A) certificates representing shares of Surviving Corporation
Common Stock, (B) cash in lieu of fractional shares and (C) any unpaid dividends
and other distributions. Upon surrender of a Certificate for cancellation to the
Exchange Agent together with such letter of transmittal, duly executed, the
holder of that Certificate shall be entitled to receive in exchange (1) a
certificate representing that number of whole shares of Surviving Corporation
Common Stock that the holder is entitled to receive under this Article II, (2) a
check in the amount (after giving effect to any required tax withholding) of (x)
any cash in lieu of fractional shares plus (y) any unpaid cash dividends and any
other dividends or other distributions (other than stock dividends) that such
holder has the right to receive under the provisions of this Article II, and the
Certificate so surrendered shall immediately be canceled. No interest will be
paid or accrued on any amount payable upon due surrender of the Certificates. In
the event of a transfer of ownership of Interstate Common Stock or any
Interstate Convertible Securities that is not registered in the transfer records
of Interstate, a certificate representing the proper number of shares of
Surviving Corporation Common Stock, together with a check for any cash to be
paid upon the surrender of the Certificate and any other dividends or
distributions in respect of those shares, may be issued or paid to such
transferee if the Certificate formerly representing such Interstate Common Stock
or any Interstate Convertible Securities is presented to the Exchange Agent,
accompanied by all documents required to evidence and effect the transfer and to
evidence that any applicable stock transfer taxes have been paid. If any
certificate for shares of Surviving Corporation Common Stock is to be issued in
a name other than that in which the surrendered Certificate is registered, it
shall be a condition of such exchange that the person requesting such exchange
shall pay any transfer or other taxes required by reason of the issuance of
certificates for shares of Surviving Corporation Common Stock in a name other
than that of the registered holder of the surrendered Certificate, or shall
establish to the satisfaction of the Surviving Corporation or the Exchange Agent
that such tax has been paid or is not applicable.

            (c) DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED INTERSTATE COMMON
STOCK. Whenever a dividend or other distribution is declared by MeriStar or the
Surviving Corporation in respect of MeriStar Common Stock or Surviving
Corporation Common Stock and the record date for that dividend or other
distribution is at or after the Effective Time, that declaration shall include
dividends or other distributions in respect of all shares issuable under this
Agreement. No dividends or other distributions in respect of Surviving
Corporation Common Stock shall be paid to any holder of any unsurrendered
Certificate until that Certificate is surrendered for exchange in accordance
with this Article II. Subject to the effect of applicable Laws, following
surrender of any such Certificate, there shall be issued or paid to the holder
of the certificates representing whole shares of Surviving Corporation Common
Stock issued in exchange therefor, without interest, (i) at the time of such
surrender, the dividends or other distributions with a record date after the
Effective Time and a payment date on or prior to the date of issuance of such
whole shares of Surviving Corporation Common Stock and not previously paid, and
(ii) at the appropriate payment date, the dividends or other distributions
payable with respect to such whole shares of Surviving Corporation Common Stock
with a record date after the Effective Time but with a payment date subsequent
to surrender. For purposes of dividends or other distributions in respect of
shares of Surviving Corporation Common Stock, all shares of Surviving
Corporation Common Stock to be issued pursuant to the Merger shall be deemed
issued and outstanding as of the Effective Time.


                                       5
<Page>

            (d) NO FURTHER OWNERSHIP RIGHTS IN INTERSTATE COMMON STOCK. Each
Certificate shall be deemed at any time after the Effective Time to represent
only the right to receive the Merger Consideration, as contemplated by this
Section 2.2. All shares of Surviving Corporation Common Stock, together with any
cash paid under Section 2.2(c) hereof or Section 2.2(f) hereof issued upon the
surrender for or exchange of Certificates in accordance with the terms of this
Agreement, shall be deemed to have been issued in full satisfaction of all
rights pertaining to the shares of Interstate Common Stock formerly represented
by such Certificates.

            (e) NO FURTHER TRANSFERS. After the Effective Time, the stock
transfer books of Interstate shall be closed, and there shall be no further
registration of transfers on the records of Interstate of the shares of
Interstate Common Stock that were outstanding immediately prior to the Effective
Time.

            (f) FRACTIONAL SHARES. No certificates or scrip representing
fractional shares of Surviving Corporation Common Stock shall be issued upon the
surrender for exchange of Certificates, and such fractional share interest shall
not entitle its owner to vote, to receive dividends or to any other rights of a
stockholder of the Surviving Corporation. Each holder of a fractional share
interest shall be paid an amount in cash equal to the product obtained by
multiplying (A) the fractional share interest to which such holder would
otherwise be entitled (after taking into account all shares of Interstate Common
Stock held at the Effective Time by such holder) by (B) the closing price for a
share of MeriStar Common Stock as reported on the New York Stock Exchange (the
"NYSE") Composite Tape as reported by the Dow Jones News Services on the first
trading day immediately preceding the date on which the Effective Time occurs.
As promptly as practicable after the determination of the amount of cash, if
any, to be paid to the holders of fractional share interests, the Exchange Agent
shall so notify MeriStar prior to the Effective Time, or the Surviving
Corporation after the Effective Time, and MeriStar or the Surviving Corporation,
as applicable, shall deposit such amounts with the Exchange Agent (and such
amount shall become part of the Exchange Fund) and cause the Exchange Agent to
forward payments to such holders in accordance with Sections 2.2(b) and (c)
hereof.

            (g) TERMINATION OF EXCHANGE FUND. Any shares of Surviving
Corporation Common Stock and any portion of the Exchange Fund or of dividends or
other distributions with respect to Surviving Corporation Common Stock deposited
by the Surviving Corporation with the Exchange Agent (including the proceeds of
any investments of those funds) that remains unclaimed by the former
stockholders of Interstate 180 days after the Effective Time shall be paid to
the Surviving Corporation. Any former stockholders of Interstate who have not
theretofore complied with this Article II shall thereafter look only to the
Surviving Corporation for payment of their Merger Consideration and any
dividends and other distributions issuable or payable pursuant to Section 2.2(c)
hereof upon due surrender of their Certificates (or affidavits of loss in lieu
of Certificates), in each case, without any interest. Notwithstanding the
foregoing, none of the Surviving Corporation, the Exchange Agent or any other
person shall be liable to any former holder of shares of Interstate Common Stock
for any amount properly delivered to a public official under applicable
abandoned property, escheat or similar Laws. If any Certificates shall not have
been surrendered prior to five years after the Effective Time (or immediately
prior to such earlier date on which any Merger Consideration in respect of such
Certificate would otherwise escheat to or become the property of any
Governmental Entity), any


                                       6
<Page>

amounts payable in respect of such Certificate shall, to the extent permitted by
applicable Law, become the property of the Surviving Corporation, free and clear
of all claims or interests of any person previously entitled to those amounts.

            (h) LOST CERTIFICATES. In the event any Certificate shall have been
lost, stolen or destroyed, upon the making of an affidavit of that fact by the
person claiming such Certificate to be lost, stolen or destroyed and the posting
by such person of a bond in the form customarily required by the Surviving
Corporation as indemnity against any claim that may be made against it with
respect to such Certificate, the Exchange Agent shall issue in exchange for such
lost, stolen or destroyed Certificate the shares of Surviving Corporation Common
Stock, any unpaid dividends or other distributions and any cash payment in lieu
of a fractional share in respect of that Certificate issuable or payable under
this Article II upon due surrender thereof and deliverable in respect of the
shares of Interstate Common Stock and associated Interstate Stockholder Rights
represented by such Certificate under this Agreement, in each case, without
interest.

      Section 2.5 APPRAISAL RIGHTS. In accordance with Section 3-202(c) of the
MGCL, no appraisal rights shall be available to holders of shares of Interstate
Class A Common Stock in connection with the Merger. In accordance with Section
3-202 of the MGCL, appraisal rights shall be available to the holders of shares
of Interstate Class B Common Stock and Interstate Series B Preferred Stock in
connection with the Merger.

      Section 2.6 ADJUSTMENTS TO PREVENT DILUTION. In the event that prior to
the Effective Time there is a change in the number of shares of Interstate
Common Stock or shares of the common stock, par value $0.01 per share, of
MeriStar (the "MERISTAR COMMON STOCK") or securities convertible or exchangeable
into or exercisable for shares of Interstate Common Stock or shares of MeriStar
Common Stock issued and outstanding as a result of a distribution,
reclassification, stock split (including a reverse stock split), stock dividend
or distribution or other similar transaction (other than as contemplated by this
Agreement), the Exchange Ratio shall be equitably adjusted to eliminate the
effects of that event.

      Section 2.7 WITHHOLDING RIGHTS. The Surviving Corporation shall be
entitled to deduct and withhold from any amounts otherwise payable pursuant to
this Agreement to any holder of a Certificate such amounts as it is required to
deduct and withhold with respect to the making of such payment under the Code,
or any provisions of applicable Law. To the extent that amounts are so withheld
by the Surviving Corporation, such withheld amounts shall be treated for
purposes of this Agreement as having been paid to the holder of a Certificate in
respect to which such deduction and withholding was made by the Surviving
Corporation.

      Section 2.8 STOCK OPTIONS.

            (a) Prior to the Effective Time, MeriStar and Interstate shall take
all such actions as may be necessary to cause each outstanding Interstate Stock
Option to be automatically assumed and converted at the Effective Time into an
option (a "MERISTAR EXCHANGE OPTION") to purchase that number of shares of
Surviving Corporation Common Stock equal to the number of shares of Interstate
Common Stock issuable immediately prior to the Effective Time upon exercise of
such Interstate Stock Option (without regard to actual restrictions on


                                       7
<Page>

exercisability) multiplied by the Exchange Ratio, with an exercise price equal
to the exercise price that was in effect under such Interstate Stock Option
immediately prior to the Effective Time divided by the Exchange Ratio, and with
such MeriStar Exchange Option being otherwise subject to the same terms and
conditions as the terms and conditions of such Interstate Stock Option
immediately before the Effective Time. It is the intention of the parties that
the options so assumed by the Surviving Corporation qualify following the
Effective Time as "incentive stock options," as defined in Section 422 of the
Code, if and to the extent such options qualified as incentive stock options
prior to the Effective Time. In connection with the granting of MeriStar
Exchange Options, the Surviving Corporation shall (i) reserve for issuance the
aggregate number of shares of Surviving Corporation Common Stock that will
become subject to MeriStar Exchange Options pursuant to this Section 2.6, (ii)
from and after the Effective Time, upon exercise of MeriStar Exchange Options,
make available for issuance all shares of Surviving Corporation Common Stock
covered thereby, subject to the terms and conditions applicable thereto, and
(iii) within 10 business days following the Effective Time, file a registration
statement with the SEC on Form S-8 covering the issuance of shares of Surviving
Corporation Common Stock upon exercise of the MeriStar Exchange Options.

            (b) Each MeriStar Stock Option granted under the MeriStar Option
Plan that is outstanding (whether or not then exercisable) as of immediately
prior to the Effective Time and that has not been exercised or canceled prior
thereto, shall, at the Effective Time, survive the Merger, be deemed exercisable
only for shares of Surviving Corporation Common Stock and continue to have, and
be subject to, the same terms and conditions as set forth in the MeriStar Option
Plan, as amended, and any relevant option agreements (as in effect immediately
prior to the Effective Time) pursuant to which it was granted.

            ARTICLE III REPRESENTATIONS AND WARRANTIES OF INTERSTATE

Section 3.11 of the Interstate Disclosure Letter, neither Interstate nor any
Interstate Subsidiary, nor to Interstate's knowledge, any other person, is in
violation of or in default under (nor does there exist any condition which with

investigations (collectively, "CLAIMS") that are uninsured (in whole or in
part), pending or, to the knowledge of Interstate, threatened against Interstate

be expected to result in a Material Adverse Effect on Interstate. Neither

                  (iii) Section 3.14(a)(iii) of the Interstate Disclosure Letter
sets forth and describes the status, as of the date of this Agreement, of any
material agreements involving Intellectual Property currently in negotiation or
proposed ("PROPOSED INTELLECTUAL PROPERTY AGREEMENTS") by Interstate or the
Interstate Subsidiaries.

            (b) OWNERSHIP. Except as set forth in Section 3.14(b) of the
Interstate Disclosure Letter, Interstate or the Interstate Subsidiaries
exclusively own the entire right, title and interest to (or otherwise have the
right to use pursuant to a valid license, sublicense or other agreement), free
and clear of all Liens, and have the unrestricted right to use, sell or license
(subject to any such license terms, as applicable) all Intellectual Property,
and have the right to bring actions for infringement of all of their owned
Intellectual Property, except, with respect to any of the above, where the
failures to so own or have such rights, individually or in the aggregate, have
not resulted and could not reasonably be expected to result in a Material
Adverse Effect on Interstate.

            (c) CLAIMS. Except as set forth in Section 3.14(c) of the Interstate
Disclosure Letter, neither Interstate nor any of the Interstate Subsidiaries has
been, during the three years preceding the date of this Agreement, a party to

challenges the validity, enforceability, ownership, or right to use, sell, or
license any of its Intellectual Property, except for Claims that, individually
or in the aggregate, have not resulted and could not reasonably be expected to
result in a Material Adverse Effect on Interstate. To the knowledge of
Interstate, no third party is infringing upon or otherwise violating any
Intellectual Property of Interstate or any of the Interstate Subsidiaries,
except for infringements or violations that, individually or in the aggregate,
have not resulted and could not reasonably be expected to result in a Material
Adverse Effect on Interstate. To the knowledge of Interstate, none of the
Intellectual Property owned, licensed or used by it or any Interstate Subsidiary
infringes upon or otherwise violates any intellectual property rights of others.

            (d) ADMINISTRATION AND ENFORCEMENT. Interstate and the Interstate
Subsidiaries have taken all necessary and desirable actions to maintain and
protect each item of


                                       21
<Page>

Intellectual Property owned by Interstate or any Interstate Subsidiary, except
for failures to take such actions that, individually or in the aggregate, have
not resulted and could not reasonably be expected to result in a Material
Adverse Effect on Interstate. To the knowledge of Interstate, all of the
Intellectual Property rights of Interstate and the Interstate Subsidiaries are
valid and enforceable.

            (e) PROTECTION OF TRADE SECRETS AND TECHNOLOGY. Without limiting the
generality of Section 3.14(d) hereof, Interstate and the Interstate Subsidiaries
have taken all reasonable precautions to protect the secrecy, confidentiality,
and value of their trade secrets and the proprietary nature and value of their
Technology and other Intellectual Property, except for failures to take such
precautions that, individually or in the aggregate, have not resulted and could
not reasonably be expected to result in a Material Adverse Effect on Interstate.

            (f) EFFECT OF TRANSACTION. Neither Interstate nor any of the
Interstate Subsidiaries is, nor, as a result of the execution and delivery of
this Agreement or its performance of its obligations hereunder, will be, in
violation of any agreement relating to any Intellectual Property, except for
violations that, individually or in the aggregate, could not reasonably be
expected to result in a Material Adverse Effect on Interstate. After the
completion of the transactions contemplated by this Agreement, Interstate and
the Interstate Subsidiaries will continue to own all right, title, and interest
in and to or have a license to use all their Intellectual Property on identical
terms and conditions as Interstate and the Interstate Subsidiaries enjoyed
immediately prior to such transactions, except for failures to own or have
available for use that, individually or in the aggregate, have not resulted and
could not reasonably be expected to result in a Material Adverse Effect on
Interstate.

      Section 3.15 TAXES. Except as set forth in Section 3.15 of the Interstate
Disclosure Letter and except as has not had and could not reasonably be expected
to have, individually or in the aggregate, a Material Adverse Effect on
Interstate:

            (a) Interstate and each Interstate Subsidiary has timely filed or
caused to be filed all Tax Returns required to be filed by or with respect to
it, its operations and assets, and has paid or caused to be paid or, in respect
of Taxes not yet due, has accrued, all Taxes shown thereon as owing. All Tax
Returns filed by Interstate or any Interstate Subsidiary were prepared in
compliance with all applicable Laws and regulations and were true, complete, and
correct in all respects as of the date on which they were filed or as
subsequently amended to the date hereof. Complete copies of federal, state,
local, and foreign Tax Returns of Interstate and each Interstate Subsidiary for
each of the years ended 2000 and 1999 have heretofore been delivered or made
available to MeriStar. Prior to the date hereof, Interstate has provided to
MeriStar copies of all revenue agents' reports and other written assertions of
deficiencies or other liabilities for Taxes of Interstate and each Interstate
Subsidiary with respect to past periods for which the applicable statute of
limitations has not expired. As used in this Agreement, (i) "TAX" or "TAXES"
shall mean all taxes of any kind, charges, fees, customs, duties, imposts,
levies or other assessments, including, without limitation, all net income,
gross receipts, ad valorem, value added, transfer, gains, franchise, profits,
inventory, net worth, capital stock, asset, sales, use, license, estimated
withholding, payroll, transaction, capital, employment, social security, workers
compensation, unemployment, excise, any interest and any penalties, additions to
tax or additional amounts, imposed by any taxing authority (domestic or foreign)
and shall include any


                                       22
<Page>

transferee liability in respect of Taxes; and (ii) "TAX RETURNS" shall mean all
returns, reports, or similar statements required to be filed with respect to any
Tax (including any attached schedules), including, without limitation,
information returns, claims for refund, amended returns, or declarations of
estimated Tax.

            (b) Interstate and each Interstate Subsidiary has timely paid or
caused to be paid all Taxes for which a notice of, or assessment or demand for,
payment has been received or which are otherwise due and payable with respect to
Interstate or any Interstate Subsidiary, its operations and assets, except for
Taxes that are being contested in good faith by appropriate proceedings (all of
which are disclosed on Section 3.15(b) of the Interstate Disclosure Letter) and
for payment of which Taxes adequate reserves will have been set up as of the
Closing Date.

            (c) Interstate and each of the Interstate Subsidiaries has complied
with all applicable Laws, rules, and regulations relating to the withholding of
Taxes and has timely collected or withheld and paid over to the proper
governmental authorities all amounts shown to be owing or withheld on its Tax
Returns and paid over for all prior periods under all applicable Laws.

            (d) There are no outstanding agreements, waivers, or arrangements
extending the statutory period of limitations for the assessment or collection
of Taxes with respect to any Tax Return that relates to Interstate or any
Interstate Subsidiary, which waivers or extensions currently are in effect, and
no request for any such waiver or extension is currently pending.

            (e) There are no Tax rulings, request for rulings, or closing
agreements relating specifically to Interstate or any Interstate Subsidiary
which could affect its liability for Taxes for any period after the Closing
Date.

            (f) No action, suit, proceeding, investigation, audit, claim, or
assessment is presently pending or to the knowledge of Interstate, proposed with
regard to any Taxes that relate to Interstate or any Interstate Subsidiary for
which Interstate or any Interstate Subsidiary would or could be liable. None of
Interstate or any Interstate Subsidiary has received a request from any taxing
authority for information with respect to Taxes of Interstate or the Interstate
Subsidiaries. Neither Interstate nor any Interstate Subsidiary has any knowledge
of any fact or condition that, if known to any taxing authority having
jurisdiction, would likely result in the issuance of a notice of proposed
deficiency or similar notice of intention to assess Taxes against Interstate or
the Interstate Subsidiaries, and no issue has arisen in any examination of
Interstate or the Interstate Subsidiaries by any taxing authority that if raised
with respect to any other period not so examined would result in a material
deficiency for any other period not so examined, if upheld.

            (g) Neither Interstate nor any of the Interstate Subsidiaries (i)
has agreed to or is required to make any adjustment pursuant to Section 481 of
the Code (or any predecessor or similar provision of other Laws or regulations)
by reason of a change in accounting method or otherwise; (ii) has knowledge that
any taxing authority has proposed any such adjustment or change which proposal
is currently pending; or (iii) has an application


                                       23
<Page>

pending with any taxing authority requesting permission for any change in
accounting methods that relates to its business and operations.

            (h) Neither Interstate nor any Interstate Subsidiary (i) is a party
to, is bound by, or has any obligation under, any Tax sharing agreement or
similar contract, (ii) has any current or potential contractual obligation to
indemnify any other person with respect to Taxes, or (iii) has any obligation to
make distributions in respect of Taxes.

            (i) No Taxes are delinquent or constitute a lien (other than with
respect to Taxes which are not yet due and payable) against Interstate or any
Interstate Subsidiary, except with respect to Taxes being contested in good
faith by appropriate proceedings (all of which are disclosed on Section 3.15(i)
of the Interstate Disclosure Letter) and for payment of which Taxes adequate
reserves have been established.

            (j) There is no contract, agreement, plan, or arrangement covering
any person that, individually or collectively, could give rise to the payment of
any amount that would not be deductible by Interstate or any Interstate
Subsidiary by reason of Section 280G of the Code.

            (k) The unused "net operating losses" (as defined in Section 172 of
the Code) of Interstate and each Interstate Subsidiary as reflected on the
applicable Tax Returns, and the years in which all such net operating losses
arose and will expire are set forth on Section 3.15(k) of the Interstate
Disclosure Letter.

            (l) To the knowledge of Interstate, no property of Interstate or any
Interstate Subsidiary is "tax-exempt use property" within the meaning of Section
168 of the Code.

            (m) Neither Interstate nor, to the knowledge of Interstate, any of
its affiliates has taken or agreed to take any action, nor is Interstate aware
of any agreement, plan or other circumstance, that would prevent the Merger from
constituting a transaction qualifying as a reorganization under Section 368(a)
of the Code.

            (n) Neither Interstate nor any Interstate Subsidiary has been either
a distributing or controlled corporation within the meaning of Section 355 of
the Code within the two years preceding the date of this Agreement.

      Section 3.16 NON-COMPETITION AGREEMENTS.

            (a) Section 3.16(a) of the Interstate Disclosure Letter sets forth a
complete and accurate list of any Contract to which Interstate or any Interstate
Subsidiary is a party which purports to restrict or prohibit Interstate or any
Interstate Subsidiary collectively from, directly or indirectly, engaging in any
business currently engaged in by Interstate, any Interstate Subsidiary or any
other persons affiliated with Interstate. Except as set forth in Section 3.16(a)
of the Interstate Disclosure Letter or as has not had and could not reasonably
be expected to have, individually or in the aggregate, a Material Adverse Effect
on Interstate, neither Interstate nor any Interstate Subsidiary is a party to
any Contract which purports to restrict or prohibit Interstate or any Interstate
Subsidiary collectively from, directly or indirectly,


                                       24
<Page>

engaging in any business currently engaged in by Interstate, any Interstate
Subsidiary or any other persons affiliated with Interstate and none of
Interstate's officers, directors or key employees is a party to any agreement
which, by virtue of such person's relationship with Interstate, restricts
Interstate or any Interstate Subsidiary or affiliate of either of them from,
directly or indirectly, engaging in any of the businesses described above.

            (b) Assuming the completeness and accuracy of the list of names and
addresses of the properties contained in Section 4.29(a) of the MeriStar
Disclosure Letter, Section 3.16(b) of the Interstate Disclosure Letter sets
forth a complete and accurate list of each management agreement, franchise
agreement or other agreement to which Interstate or any Interstate Subsidiary is
a party that contains any restrictions on engaging in any business (or the
geographical scope of such business) currently engaged in by Interstate, any
Interstate Subsidiary, any other persons affiliated with Interstate or by
MeriStar, any MeriStar Subsidiary or any other persons affiliated with MeriStar,
in each case, that would be breached or violated or that would result in the
restriction or termination of such management agreement as a result of the
execution, delivery or performance of this agreement or the consummation of the
transactions contemplated hereby.

      Section 3.17 AGREEMENTS WITH REGULATORY AGENCIES. Except as set forth in
Section 3.17 of the Interstate Disclosure Letter, neither Interstate nor any

by, or is a party to any written agreement, consent agreement or memorandum of
understanding with, or is a party to any commitment letter or similar
undertaking to, or is subject to any order or directive by, or is a recipient of
any extraordinary supervisory letter from, or has adopted any board resolutions
at the request of (each, whether or not listed in Section 3.17 of the Interstate
Disclosure Letter, a "INTERSTATE REGULATORY AGREEMENT" ), any Governmental
Entity that restricts the conduct of its business, except for any Interstate
Regulatory Agreements that, individually or in the aggregate, have not resulted
and could not reasonably be expected to result in a Material Adverse Effect on
Interstate. Neither Interstate nor any Interstate Subsidiary has been advised by
any Governmental Entity that such Governmental Entity is considering issuing or
requesting any Interstate Regulatory Agreement, except for any such proposed
Interstate Regulatory Agreements that, individually or in the aggregate, could
not reasonably be expected to result in a Material Adverse Effect on Interstate.

      Section 3.18 OPINION OF FINANCIAL ADVISOR. Merrill Lynch & Co. (the
"INTERSTATE FINANCIAL ADVISOR") has delivered to the Board of Directors of
Interstate its opinion to the effect that, as of the date of this Agreement,
the Transaction (as defined therein) is fair, from a financial point of view,
to the holders of Interstate Common Stock, other than the Investor, whether
or not the Merger is consummated, which opinion will be accompanied by an
authorization to include a copy of such opinion in the Proxy Materials.
Interstate will deliver to MeriStar a signed copy of the written opinion for
informational purposes only promptly after receipt by Interstate of such
opinion.

      Section 3.19 BROKERS. No broker, finder, investment banker or financial
advisor other than the Interstate Financial Advisor is entitled to any
brokerage, finder's or other fee or commission in connection with the Merger or
the other transactions contemplated by this Agreement based upon arrangements

their affiliates. Prior to the date of this Agreement, Interstate has made

<Page>

to MeriStar a complete and correct copy of all agreements between Interstate or
any of the Interstate Subsidiaries or their affiliates and the Interstate
Financial Advisor under which the Interstate Financial Advisor would be entitled
to any payment relating to the Merger or such other transactions.

      Section 3.20 CERTAIN STATUTES. The Board of Directors of Interstate has
taken or will take all appropriate and necessary actions to ensure that the
restrictions on business combinations in Sections 3-602 and 3-603 of the MGCL
will not have any effect on the Merger or the other transactions contemplated by
this Agreement. No "fair price," "moratorium," "control share acquisition" or
other similar state or federal anti-takeover statute or regulation (each a
"TAKEOVER STATUTE") is, as of the date of this Agreement, applicable to the
Merger or such other transactions.

      Section 3.21 INFORMATION. None of the information to be supplied by

statement of a material fact or omit to state any material fact required to be
stated in the Proxy Statement or necessary in order to make the statements in
the Proxy Statement, in light of the circumstances under which they are made,
not misleading. The Proxy Statement (except for those portions of the Proxy
Statement that relate only to MeriStar or the MeriStar Subsidiaries or
affiliates of MeriStar) will comply as to form in all material respects with the
provisions of the Exchange Act.

      Section 3.22 VOTE REQUIRED. The Requisite Interstate Vote is the only vote
of the holders of any class or series of Interstate's capital stock necessary
(under the rules and regulations of the NASDAQ, Interstate's charter and bylaws,

Merger or the other transactions contemplated by this Agreement.

      Section 3.23 PROPERTIES.

            (a) Section 3.23(a)(i) of the Interstate Disclosure Letter sets

Interstate Properties to which Interstate or a Interstate Subsidiary owns fee

such Interstate Property, and (2) for those Interstate Properties leased by
Interstate or a Interstate Subsidiary, such lessee holds valid leasehold title
to such Interstate Property, which title is, in each case described in clauses

Encumbrances, Interstate Ordinary Course Leases and the Interstate Space Leases
and Encumbrances for taxes not yet due and payable or which are not being

reasonably be expected to have a Material Adverse Effect on Interstate.

            (b) Except as set forth in Section 3.23(b) of the Interstate
Disclosure Letter, and except for matters which could not, individually or in
the aggregate, reasonably be expected to have a Material Adverse Effect on
Interstate or to materially and adversely affect the use or occupancy (or, if
applicable, any proposed developments) of the Interstate Properties in a manner
which could reasonably be expected to have a Material Adverse Effect on
Interstate, Interstate has no knowledge that any currently required certificate,
permit or license (including building permits and certificates of occupancy)
from any Governmental Entity having jurisdiction over any Interstate Property
has not been obtained or is not in full force and effect or is subject to any
pending modification or cancellation.

            (c) Section 3.23(c) of the Interstate Disclosure Letter sets forth a
complete and accurate list of all definitive agreements made or entered into by
Interstate or any Interstate Subsidiary as of the date hereof, (x) to sell,

the ownership or financing of the interest of Interstate or such Interstate
Subsidiary in any Interstate Property or (y) to purchase real property to which
Interstate or any Interstate Subsidiary is a party.

            (d) Except as set forth in Section 3.23(d) of the Interstate

sale, mortgage, pledge, hypothecation, assignment, sublease or lease of any
material portion of the Interstate Property or Interstate's or any Interstate
Subsidiary's interest therein or other transfer of all or any part of any
Interstate Property or Interstate's or any Interstate Subsidiary's interest
therein, except for (i) leases or subleases entered into in the ordinary course
of business for long-term stay rental units, newsstands, gift shops, restaurants
and other establishments customarily located in hotel properties, (ii) leases
and subleases of rooftops and other portions of the Interstate Properties for
telecommunications purposes and (iii) other leases, subleases and similar
agreements the existence of which could not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect on Interstate
(collectively, "INTERSTATE ORDINARY COURSE LEASES").

            (e) The leases underlying the leased Interstate Properties
referenced in Section 3.23(a)(i) of the Interstate Disclosure Letter
(collectively, the "INTERSTATE LEASES") are


                                       27
<Page>

accurately set forth in Section 3.23(e) of the Interstate Disclosure Letter.
Each of the Interstate Leases is valid, binding and in full force and effect as
against Interstate or the Interstate Subsidiaries and, to Interstate's
knowledge, as against the other party thereto, except to the extent the failure
to be binding and in full force and effect could not reasonably be expected to
have a Material Adverse Effect on Interstate. There does not exist under any of
the Interstate Leases any default or event of default by Interstate or any
Interstate Subsidiary or, to the knowledge of Interstate, any default or event
of default of any other party, and, to Interstate's knowledge, no event has
occurred which, with notice or lapse of time or both, would constitute such a
default or event of default, except as could not, individually or in the
aggregate, be reasonably expected to result in a Material Adverse Effect on
Interstate.

            (f) Section 3.23(f) to the Interstate Disclosure Letter sets forth a
list of the hotel franchise agreements (the "INTERSTATE FRANCHISE AGREEMENTS")
under which Interstate or any Interstate Subsidiary is a franchisee. Each of the
Interstate Franchise Agreements is valid, binding and in full force and effect
(except to the extent the failure to be binding and in full force and effect
could not, individually or in the aggregate, reasonably be expected to result in
a Material Adverse Effect on Interstate). There are no defaults under the
Interstate Franchise Agreements by Interstate or any Interstate Subsidiary or,
to the knowledge of Interstate, by any other party thereto, nor have any events
occurred which with the giving of notice or the passage of time or both would
constitute such a default or event of default thereunder, except as could not,
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect on Interstate.

            (g) Section 3.23(g) of the Interstate Disclosure Letter sets forth
all material leases, subleases, licenses, time-share and other agreements, other
than Interstate Ordinary Course Leases (collectively, the "INTERSTATE SPACE
LEASES"), granting to any person or entity other than Interstate or any
Interstate Subsidiary any right to the possession, use, occupancy or enjoyment
of the Interstate Properties or any portion thereof. Each Interstate Space Lease
is valid, binding and in full force and effect, all rent and other sums and
charges payable by the tenant or occupant thereunder (a "INTERSTATE SPACE
TENANT") are current, no notice of default or termination under any Interstate
Space Lease is outstanding, no termination event or condition or uncured default
on the part of Interstate or any Interstate Subsidiary or, to the knowledge of
Interstate, the Interstate Space Tenant, exists under any Interstate Space
Lease, and no event has occurred and no condition exists that, with the giving
of notice or the lapse of time, or both, would constitute such a default or
termination event or condition, except where such default, termination,
termination event, condition or failure to be valid, binding and in full force
and effect, individually or in the aggregate, has not had and could not
reasonably be expected to have a Material Adverse Effect on Interstate.

            (h) Each of Interstate and the Interstate Subsidiaries owns good and
valid title to or holds valid leasehold title to, as the case may be, all of its
material tangible personal property and assets (other than the Interstate
Properties) used in, held for use in or which are necessary for the conduct of
the business of Interstate as currently conducted, except where the failure to
hold good and valid title to such property and assets, individually or in the

other illegal payment.

      Section 3.31 INTERSTATE INSURANCE BUSINESS.

            (a) Each Interstate Subsidiary that is an insurance company (each, a
"INTERSTATE INSURANCE SUBSIDIARY") is listed in Section 3.31(a) of the
Interstate Disclosure Letter.

            (b) Interstate has previously provided to MeriStar copies of audited
annual and unaudited quarterly convention statements (the "INTERSTATE SAP
FINANCIAL STATEMENTS") as filed with the domiciliary state insurance departments
of each Interstate Insurance Subsidiary as of and for the years ended December
31, 2001, 2000 and 1999, prepared in compliance with GAAP. Each of the
Interstate SAP Financial Statements fairly presents in all material respects the
results of operations of the applicable Interstate Insurance Subsidiary for the
period therein set forth, in each case in accordance with SAP. The schedules
included in the Interstate SAP Financial Statements, when considered in relation
to the basic statutory financial statements included therein, present fairly in
all material respects the information shown therein. Except as set forth in
Section 3.31(b) of the Interstate Disclosure Letter, when filed, each of the
Interstate SAP Financial Statements was correct in all material respects when
filed and did not omit to state any material facts required to be stated or
necessary in order to make the Interstate SAP Financial Statements not
misleading.

            (c) Each outstanding insurance contract (each, a "INTERSTATE
INSURANCE CONTRACT") issued, reinsured or underwritten by a Interstate Insurance
Subsidiary is listed in Section 3.31(c) of the Interstate Disclosure Letter,
together with the maximum amount payable by Interstate or any of the Interstate
Subsidiaries thereunder. All outstanding reinsurance, coinsurance and other
similar contracts ("INTERSTATE REINSURANCE CONTRACTS") with respect to such
Interstate Insurance Contracts are listed in Section 3.31(c) of the Interstate
Disclosure Letter. All Interstate Insurance Contracts and Interstate Reinsurance
Contracts are, to the extent required under applicable Laws, on forms approved
by the insurance regulatory authority of the jurisdiction where issued or filed
and have not been objected to by such authority within the period provided for
objection and have been filed or registered as required with all other
applicable Governmental Entities.

            (d) All benefits payable with respect to each Interstate Insurance
Contract by a Interstate Insurance Subsidiary or, to the knowledge of
Interstate, by any other person that is a party to or bound by such Interstate
Insurance Contract, have in all material


                                       31
<Page>

respects been paid in accordance with the terms of such Interstate Insurance
Contract. All benefits payable with respect to each Interstate Reinsurance
Contract, have in all material respects been paid in accordance with the terms
of such Interstate Reinsurance Contract.

            (e) All Interstate Insurance Contracts and Interstate Reinsurance
Contracts have been marketed and sold in compliance with all applicable Laws,
except as could not reasonably be expected to result in a Material Adverse
Effect on Interstate.

            (f) No Interstate Insurance Subsidiary has received any written, or
to the knowledge of Interstate, oral information that would cause it to believe
that the financial condition of any other party to any Interstate Insurance
Contract or Interstate Reinsurance Contract is so impaired as to be reasonably
likely to result in a default by such party under such contract.

            (g) The loss runs for the years ended December 31, 2001, 2000 and
1999, which have previously been provided by Interstate to MeriStar in writing,
are true, correct and complete in all material respects.

            (h) Except as set forth in Section 3.31(h) of the Interstate
Disclosure Letter, all reserves and other liabilities with respect to insurance
and for claims and benefits incurred but not reported ("RESERVE LIABILITIES") as
established or reflected in the Interstate SAP Financial Statements (i) were
determined in accordance with generally accepted actuarial standards
consistently applied, (ii) are fairly stated in accordance with sound actuarial
principles, (iii) are based on actuarial assumptions that are in accordance with
those called for by the relevant Interstate Insurance Contract and the related
Interstate Reinsurance Contract and (iv) meet in all material respects the
requirements of all applicable insurance Laws. Adequate provision for such
Reserve Liabilities has been made (under generally accepted actuarial principles
consistently applied) to cover the total amount of all reasonably anticipated
matured and unmatured benefits, dividends, claims and other liabilities of the
Interstate Insurance Subsidiaries under all Interstate Insurance Contracts and
Interstate Reinsurance Contracts (including, without limitation, any liability
arising under or as a result of any reinsurance, coinsurance or other similar
contract) on the date of such Interstate SAP Financial Statement based on then
current information that forms a reasonable basis for such determination. Each
of the Interstate Insurance Subsidiaries owns assets that qualify as legal
reserve assets under applicable insurance Laws in an amount at least equal to
all of such Interstate Insurance Subsidiary's Reserve Liabilities.

            (i) Except as set forth in Section 3.31(i) of the Interstate
Disclosure Letter, adequate provision has been made for all estimated losses,
settlements, costs and expenses from pending suits, actions and proceedings
contemplated by the Interstate SAP Financial Statements.

            (j) Interstate has previously delivered to MeriStar true and
complete lists as of December 31, 2001 of all assets held in the investment
portfolios of the Interstate Insurance Subsidiaries. None of the investments
included in such investment portfolios is in default with respect to the payment
of principal, interest or dividends thereon or is materially impaired. All such
investments comply with all applicable Laws. Each Interstate Insurance


                                       32
<Page>

Subsidiary owns assets which qualify as admitted assets under applicable state
insurance Laws in an amount at least equal to the sum of all of its insurance
reserves and minimum statutory capital and surplus reflected on the latest
Interstate SAP Financial Statements.

            (k) Each of the Interstate Insurance Subsidiaries has filed all
reports, statements, documents, registrations, filings or submissions required
to be filed by it with any applicable Governmental Entity, which filings conform
in all material respects to any applicable Laws, except where the failure to so
file or conform could not, individually or in the aggregate, be reasonably
expected to have a Material Adverse Effect on Interstate.

            (l) Section 3.31(l) of the Interstate Disclosure Letter sets forth a
true, correct and complete listing of all securities deposited with state
insurance departments and other regulatory authorities, which deposits have been
completed in accordance with the Schedule of Deposits set forth in each
Interstate Insurance Subsidiary's December 31, 2001 annual statement.

            (m) Except as set forth in Section 3.31(m) of the Interstate
Disclosure Letter, there are no pending (or to the knowledge of Interstate,
threatened) disputes, claims, suits, arbitrations or other actions with third
parties relating to, in connection with or arising from premiums or other
amounts payable to a Interstate Insurance Subsidiary or benefits or other
amounts payable by a Interstate Insurance Subsidiary under the Interstate
Insurance Contracts or Interstate Reinsurance Contracts.

            (e) There are no Tax rulings, request for rulings, or closing

            (f) No action, suit, proceeding, investigation, audit, claim, or
assessment is presently pending or to the knowledge of MeriStar, proposed with

<Page>

the issuance of a notice of proposed deficiency or similar notice of intention
to assess Taxes against MeriStar or the MeriStar Subsidiaries, and no issue has
arisen in any examination of MeriStar or the MeriStar Subsidiaries by any taxing
authority that if raised with respect to any other period not so examined would
result in a material deficiency for any other period not so examined, if upheld.

            (g) Neither MeriStar nor any of the MeriStar Subsidiaries (i) has
agreed to or is required to make any adjustment pursuant to Section 481 of the

any taxing authority has proposed any such adjustment or change which proposal
is currently pending; or (iii) has an application pending with any taxing
authority requesting permission for any change in accounting methods that
relates to its business and operations.

is bound by, or has any obligation under, any Tax sharing agreement or similar
contract, (ii) has any current or potential contractual obligation to indemnify
any other person with respect to Taxes, or (iii) has any obligation to make
distributions in respect of Taxes.

            (i) No Taxes are delinquent or constitute a lien (other than with
respect to Taxes which are not yet due and payable) against MeriStar or any
MeriStar Subsidiary, except with respect to Taxes being contested in good faith
by appropriate proceedings (all of which are disclosed on Section 4.15(i) of the
MeriStar Disclosure Letter) and for payment of which Taxes adequate reserves
have been established.

            (j) There is no contract, agreement, plan, or arrangement covering

any amount that would not be deductible by MeriStar or any MeriStar Subsidiary
by reason of Section 280G of the Code.

            (k) The unused "net operating losses" (as defined in Section 172 of
the Code) of MeriStar and each MeriStar Subsidiary as reflected in the
applicable Tax Returns, and the years in which all such net operating losses
arose and will expire are set forth on Section 4.15(k) of the MeriStar
Disclosure Letter.

            (l) To the knowledge of MeriStar, no property of MeriStar or any
MeriStar Subsidiary is "tax-exempt use property" within the meaning of Section
168 of the Code.

            (m) Neither MeriStar nor, to the knowledge of MeriStar, any of its
affiliates has taken or agreed to take any action, nor is MeriStar aware of any

of the Code.

            (n) Neither MeriStar nor any MeriStar Subsidiary has been either a
distributing or controlled corporation within the meaning of Section 355 of the
Code within the two years preceding the date of this Agreement.

Disclosure Letter, and except for matters which could not, individually or in
the aggregate, reasonably be expected to have a Material Adverse Effect on

permit or license (including building permits and certificates of occupancy)

pending modification or cancellation.

            (c) Section 4.23(c) of the MeriStar Disclosure Letter sets forth a

under any of the MeriStar Leases any default or event of default by MeriStar or
any MeriStar Subsidiary or, to the knowledge of MeriStar, any default or event
of default of any other party, and, to MeriStar's knowledge, no event has

MeriStar.

            (f) Section 4.23(f) to the MeriStar Disclosure Letter sets forth a
list of the hotel franchise agreements (the "MERISTAR FRANCHISE AGREEMENTS")
under which MeriStar or a MeriStar Subsidiary is a franchisee. Each of the
MeriStar Franchise Agreements is valid, binding and in full force and effect
(except to the extent the failure to be binding and in full force and effect
could not, individually or in the aggregate, reasonably be expected to result in
a Material Adverse Effect on MeriStar). There are no defaults under the MeriStar
Franchise Agreements by MeriStar or a MeriStar Subsidiary or, to the knowledge
of MeriStar, by any other party thereto, nor have any events occurred which with
the giving of notice or the passage of time or both would constitute such a
default or event of default thereunder, except as could not, individually or in

MeriStar.

            (g) Section 4.23(g) of the MeriStar Disclosure Letter sets forth all

tenant or occupant thereunder (a "MERISTAR SPACE TENANT") are current, no notice
of default or termination under any MeriStar Space Lease is outstanding, no
termination event or condition or uncured default on the part of MeriStar or any
MeriStar Subsidiary or, to the knowledge of MeriStar, the MeriStar Space Tenant,
exists under any MeriStar Space Lease, and no event has occurred and no
condition exists that, with the giving of notice or the lapse of time, or both,
would constitute such a default or termination event or condition, except where
such default,


                                       51
<Page>

full force and effect, individually or in the aggregate, has not had and could
not reasonably be expected to have a Material Adverse Effect on MeriStar.

            (h) Each of MeriStar and the MeriStar Subsidiaries owns good and
valid title to or holds valid leasehold title to, as the case may be, all of its
material tangible personal property and assets (other than the MeriStar
Properties) used in, held for use in or which are necessary for the conduct of
the business of MeriStar as currently conducted, except where the failure to
hold good and valid title to such property and assets, individually or in the
aggregate, has not had, and could not reasonably be expected to have a Material
Adverse Effect on MeriStar.

            (i) MeriStar has not received notice of and, to the knowledge of
MeriStar, there is no pending, threatened or contemplated condemnation
proceeding affecting the MeriStar Property, any property with respect to which
MeriStar or any MeriStar Subsidiary is a party to a hotel management agreement
or participating lease ("MERISTAR MANAGED PROPERTY"), or any part thereof, nor
any sale or other disposition of the MeriStar Property, MeriStar Managed
Property or any part thereof in lieu of condemnation. No portion of the MeriStar
Property or MeriStar Managed Property has suffered any material damage by fire
or other casualty that has not heretofore been completely repaired and restored,
except as, individually or in the aggregate, has not had and could not
reasonably be expected to have a Material Adverse Effect on MeriStar.

copies of the MeriStar Leases and the MeriStar Space Leases that are true,
correct and complete in all material respects.

reports will not contain any untrue statement of a material fact or omit to
state any material fact required to be stated therein or necessary in order to
make the statements therein, in the light of the circumstances under which they

best efforts (through its agents or otherwise) to solicit from its stockholders

cause the Board of Directors of MeriStar to breach its fiduciary duties to
MeriStar's stockholders under applicable Law, after receipt of advice to such
effect from independent legal counsel.

            (c) MeriStar and Interstate shall coordinate and cooperate with
respect to the timing of the Interstate Stockholders Meeting and the MeriStar
Stockholders Meeting and shall use their reasonable best efforts to hold such
meetings on the same day.

      Section 5.6 ACCESS TO INFORMATION; CONFIDENTIALITY.

            (a) Except as required under any confidentiality agreement or
similar agreement or arrangement to which MeriStar or Interstate or any of their
respective subsidiaries is a party or under applicable Law or the regulations or
requirements of any securities exchange or quotation service or other self
regulatory organization with whose rules the parties are required to comply,
from the date of this Agreement to the Effective Time, MeriStar and Interstate
shall (and shall cause their respective subsidiaries to): (i) provide to the
other (and its officers, directors, employees, accountants, consultants, legal
counsel, lenders, financial advisors, investment bankers, agents and other
representatives (collectively, "REPRESENTATIVES")) access, at reasonable times
upon prior notice, to the officers, employees, agents, properties, offices and
other facilities of the other and its subsidiaries and to the books and records
thereof; and (ii) furnish promptly such information concerning the business,
properties, Contracts, assets,


                                       64
<Page>

liabilities, personnel and other aspects of the other party and its subsidiaries
as the other party or its Representatives may reasonably request. No
investigation conducted under this Section 5.6 shall affect or be deemed to
modify any representation or warranty made in this Agreement.

            (b) The parties shall comply with, and shall cause their respective
Representatives to comply with, all of their respective obligations under the
Confidentiality Agreement, dated June 13, 2001 (the "CONFIDENTIALITY
AGREEMENT"), between MeriStar and Interstate with respect to the information
disclosed under this Section 5.6, and this Section 5.6(b) shall survive the
termination of this Agreement.

      Section 5.7 NO SOLICITATION BY INTERSTATE.

            (a) Interstate shall not, nor shall it permit any of the Interstate
Subsidiaries to, nor shall it authorize or permit any Representative of
Interstate or any of the Interstate Subsidiaries to, (i) solicit, initiate, or
encourage the submission of any Interstate Acquisition Proposal (as defined
below), (ii) except to the extent permitted by paragraph (b), enter into any
agreement with respect to any Interstate Acquisition Proposal, or (iii)
participate in any discussions or negotiations regarding, or furnish to any
person any non-public information with respect to Interstate or the Interstate
Subsidiaries in connection with, or take any other action to facilitate any
inquiries or the making of any proposal that constitutes, or may reasonably be
expected to lead to, any Interstate Acquisition Proposal; PROVIDED, HOWEVER,
that prior to the Interstate Stockholders Meeting, the Board of Directors of
Interstate, to the extent required by its duties under applicable Law as
determined in good faith by a majority of the disinterested members thereof,
having received the advice of outside counsel, may, in response to unsolicited
requests therefor, participate in discussions or negotiations with, or furnish
information pursuant to an appropriate confidentiality agreement to, any person
or entity that makes or expresses a bona fide intention to make an unsolicited
Interstate Acquisition Proposal, provided that the Board of Directors of
Interstate first determines in good faith, based on the vote of a majority of
the disinterested members thereof, that such Person or entity has the ability
and financial resources to consummate a Interstate Superior Proposal (as
determined below). Without limiting the foregoing, it is understood that any
violation of the restrictions set forth in the preceding sentence by a
Representative of Interstate or of any of the Interstate Subsidiaries, whether
or not such person is purporting to act on behalf of Interstate, a Interstate
Subsidiary or otherwise, shall be deemed to be a breach of this paragraph by
Interstate. For all purposes of this Agreement, "INTERSTATE ACQUISITION
PROPOSAL" means any proposal other than a proposal by MeriStar or a MeriStar
Subsidiary, for a merger, consolidation, share exchange, business combination or
other similar transaction involving Interstate or any of its significant
subsidiaries or any proposal or offer (including, without limitation, any
proposal or offer to stockholders of Interstate), other than a proposal or offer
by MeriStar or a MeriStar Subsidiary, to acquire in any manner, directly or
indirectly, securities representing more than 30% of the outstanding voting
power of Interstate on the date hereof, or 30% or more of the consolidated
assets of Interstate. Interstate immediately shall cease and cause to be
terminated all existing discussions or negotiations with any persons conducted
heretofore with respect to, or that could reasonably be expected to lead to, any
Interstate Acquisition Proposal. Notwithstanding the foregoing, the Board of
Directors of Interstate may, after receipt of an unsolicited Interstate
Acquisition Proposal, request such information as may be necessary to determine
whether the Person or


                                       65
<Page>

entity making such Interstate Acquisition Proposal has the ability and financial
resources to consummate a Interstate Superior Proposal.

            (b) Neither the Board of Directors of Interstate nor any committee
thereof shall (i) withdraw, modify or otherwise change, or propose publicly to
withdraw, modify or otherwise change, in a manner adverse to MeriStar, the
Interstate Board Recommendation or (ii) approve or recommend, or propose to
approve or recommend, any Interstate Acquisition Proposal. Notwithstanding the
foregoing, the Board of Directors of Interstate, to the extent required by its
duties under applicable Law as determined in good faith by a majority of the
disinterested members thereof, having received the advice of outside counsel,
may approve or recommend (and, in connection therewith, withdraw or modify or
otherwise change the Interstate Board Recommendation) a Interstate Superior
Proposal (as defined below). For purposes of this Agreement, a "INTERSTATE
SUPERIOR PROPOSAL" means a bona fide written proposal made by a third party to
acquire Interstate pursuant to a tender or exchange offer, a merger, a share
exchange, a sale of all or substantially all of its assets or otherwise, in any
such case, on terms which a majority of the disinterested members of the Board
of Directors of Interstate determines in their good faith judgment (after
consultation with nationally-recognized independent financial advisors and after
taking into account all legal, financial, regulatory and other material aspects
of such proposal, the person making the proposal, the strategic benefits to be
derived from the Merger and the long-term prospects of MeriStar and the MeriStar
Subsidiaries) to be more favorable to Interstate and its stockholders than the
Merger and for which financing, to the extent required, is then fully committed
or which, in the good faith judgment of a majority of such disinterested members
(after consultation with independent financial advisors), is reasonably capable
of being obtained by such third party.

            (c) Interstate shall promptly advise MeriStar orally and in writing
of any Interstate Acquisition Proposal or any inquiry with respect to or which
could reasonably be expected to lead to any Interstate Acquisition Proposal, the
material terms and conditions of such Interstate Acquisition Proposal or inquiry
and the identity of the person making any such Interstate Acquisition Proposal
or inquiry. Interstate shall keep MeriStar fully informed of the status and
details of any such Interstate Acquisition Proposal or inquiry. Interstate shall
give MeriStar at least three days' advance notice of any information to be
supplied to, and at least five days' advance notice of any agreement to be
entered into with, any person making a Interstate Acquisition Proposal.

            (d) Nothing contained in this Section 5.7 will prohibit Interstate
from taking and disclosing to its stockholders a position contemplated by Rule
14e-2(a) promulgated under the Exchange Act or from making any disclosure to
Interstate's stockholders if the Board of Directors of Interstate determines
that such disclosure is necessary in order to comply with the Board of Directors
of Interstate's duties under applicable Law.

      Section 5.8 NO SOLICITATION BY MERISTAR.

            (a) MeriStar shall not, nor shall it permit any of the MeriStar
Subsidiaries to, nor shall it authorize or permit any Representative of MeriStar
or any of the MeriStar Subsidiaries to, (i) solicit, initiate, or encourage the
submission of, any MeriStar Acquisition Proposal (as defined below), (ii) except
to the extent permitted by paragraph (b),


                                       66
<Page>

enter into any agreement with respect to any MeriStar Acquisition Proposal, or
(iii) participate in any discussions or negotiations regarding, or furnish to
any person any non-public information with respect to MeriStar or the MeriStar
Subsidiaries in connection with, or take any other action to facilitate any
inquiries or the making of any proposal that constitutes, or may reasonably be
expected to lead to, any MeriStar Acquisition Proposal; PROVIDED, HOWEVER, that
prior to the MeriStar Stockholders Meeting, to the extent required by the duties
of the Board of Directors of MeriStar under applicable Law, as determined in
good faith by a majority of the disinterested members thereof after consultation
with and receipt of advice from independent legal counsel, MeriStar may, in
response to unsolicited requests therefor, participate in discussions or
negotiations with, or furnish information pursuant to an appropriate
confidentiality agreement to, any person or entity that makes or expresses a
bona fide intention to make an unsolicited MeriStar Acquisition Proposal,
provided that the Board of Directors of MeriStar first determines in good faith,
based on the vote of a majority of the disinterested members thereof, that such
Person or entity has the ability and financial resources to consummate a
MeriStar Superior Proposal (as determined below). Without limiting the
foregoing, it is understood that any violation of the restrictions set forth in
the preceding sentence by a Representative of MeriStar or of any of the MeriStar
Subsidiaries, whether or not such person is purporting to act on behalf of
MeriStar, a MeriStar Subsidiary or otherwise, shall be deemed to be a breach of
this paragraph by MeriStar. For all purposes of this Agreement, "MERISTAR
ACQUISITION PROPOSAL" means any proposal other than a proposal by Interstate or
a Interstate Subsidiary, for a merger, consolidation, share exchange, business
combination or other similar transaction involving MeriStar or any of its
significant subsidiaries or any proposal or offer (including, without
limitation, any proposal or offer to stockholders of MeriStar), other than a
proposal or offer by Interstate or a Interstate Subsidiary, to acquire in any
manner, directly or indirectly, securities representing more than 30% of the
outstanding voting power of MeriStar on the date hereof, or 30% or more of the
consolidated assets of MeriStar. MeriStar immediately shall cease and cause to
be terminated all existing discussions or negotiations with any persons
conducted heretofore with respect to, or that could reasonably be expected to
lead to, any MeriStar Acquisition Proposal. Notwithstanding the foregoing, the
Board of Directors of MeriStar may, after receipt of an unsolicited MeriStar
Acquisition Proposal, request such information as may be necessary to determine
whether the Person or entity making such MeriStar Acquisition Proposal has the
ability and financial resources to consummate a MeriStar Superior Proposal.

            (b) None of the Board of Directors of MeriStar nor any committee or
subcommittee thereof shall (i) withdraw, modify or otherwise change, or propose
publicly to withdraw, modify or otherwise change, in a manner adverse to
Interstate, the MeriStar Board Recommendation or (ii) approve or recommend, or
propose to approve or recommend, any MeriStar Acquisition Proposal.
Notwithstanding the foregoing, the Board of Directors of MeriStar, to the extent
required by the duties of the Board of Directors of MeriStar under applicable
Law, as determined in good faith by a majority of the disinterested members
thereof after consultation with and receipt of advice from independent legal
counsel, may approve or recommend (and, in connection therewith, withdraw or
modify or otherwise change the MeriStar Board Recommendation) a MeriStar
Superior Proposal (as defined below). For purposes of this Agreement, a
"MERISTAR SUPERIOR PROPOSAL" means a bona fide written proposal made by a third
party to acquire MeriStar pursuant to a tender or exchange offer, a merger, a
share exchange, a sale of all or substantially all of its assets or otherwise,
in any such case, on terms which a majority of the disinterested members of the
Board of Directors of MeriStar determines in their


                                       67
<Page>

good faith judgment (after consultation with nationally-recognized independent
financial advisors and after taking into account all legal, financial,
regulatory and other material aspects of such proposal, the person making the
proposal, the strategic benefits to be derived from the Merger and the long-term
prospects of Interstate and the Interstate Subsidiaries) to be more favorable to
MeriStar and its stockholders than the Merger and for which financing, to the
extent required, is then fully committed or which, in the good faith judgment of
a majority of such disinterested members (after consultation with independent
financial advisors), is reasonably capable of being obtained by such third
party.

            (c) MeriStar shall promptly advise Interstate orally and in writing
of any MeriStar Acquisition Proposal or any inquiry with respect to or which
could reasonably be expected to lead to any MeriStar Acquisition Proposal, the
material terms and conditions of such MeriStar Acquisition Proposal or inquiry
and the identity of the person making any such MeriStar Acquisition Proposal or
inquiry. MeriStar shall keep Interstate fully informed of the status and details
of any such MeriStar Acquisition Proposal or inquiry. MeriStar shall give
Interstate at least three days' advance notice of any information to be supplied
to, and at least five days' advance notice of any agreement to be entered into
with, any person making a MeriStar Acquisition Proposal.

            (d) Nothing contained in this Section 5.8 will prohibit MeriStar
from taking and disclosing to its stockholders a position contemplated by Rule
14e-2(a) promulgated under the Exchange Act or from making any disclosure to
MeriStar's stockholders if the Board of Directors of MeriStar determines that
such disclosure is necessary in order to comply with the Board of Directors of
MeriStar's duties under applicable Law.

Investment Corporation and Interstate Property Partnership, L.P. dated as of

      Section 5.10 DIRECTORS' AND OFFICERS' INDEMNIFICATION AND INSURANCE.

            (a) MeriStar agrees that all rights to indemnification now existing
in favor of any director, officer, employee or agent of Interstate and the
Interstate Subsidiaries (the "INDEMNIFIED PARTIES") as provided in their
respective corporate governance documents, in an agreement between an
Indemnified Party and Interstate or one of the Interstate Subsidiaries, or
otherwise, in each case as in effect on the date of this Agreement, shall
survive the Merger and shall continue in full force and effect for a period of
not less than six years after the Effective Time; provided that in the event any
claim or claims are asserted or made within such six-year period, all rights to
indemnification in respect of any such claim or claims shall continue until
final disposition of any and all such claims. The Surviving Corporation shall
indemnify all Indemnified Parties to the fullest extent permitted by applicable
Law with respect to all acts and omissions arising out of such individuals'
services as officers, directors, employees or agents of Interstate or any of the
Interstate Subsidiaries or as trustees or fiduciaries of any plan for the
benefit of employees, or otherwise on behalf of, Interstate or any of the
Interstate Subsidiaries, occurring prior to the Effective Time, including the
transactions contemplated by this Agreement. Without limiting the generality of
the foregoing, in the event any such Indemnified Party is or becomes involved in
any capacity in any action, proceeding or investigation in connection with any
matter, including the transactions contemplated by this Agreement, occurring at
or after the Effective Time, the Surviving Corporation shall pay as incurred
such Indemnified Party's legal and other expenses (including the cost of any
investigation and preparation) incurred in connection therewith.

            (b) MeriStar agrees that, from and after the Effective Time, the

containing terms and conditions which are no less advantageous, taken as a
whole, and


                                       69
<Page>

provided that such substitution shall not result in any gaps or lapses in
coverage with respect to matters occurring prior to the Effective Time; and
provided, further, that the Surviving Corporation shall not be required to pay
an annual premium in excess of 300% of the last annual premium paid by
Interstate prior to the date of this Agreement, and, if the Surviving
Corporation is unable to obtain the insurance required by this Section 5.10(b),
it shall obtain as much comparable insurance as possible for an annual premium
equal to such maximum amount.

            (c) The provisions of this Section 5.10 are intended to be for the
benefit of each Indemnified Party and his or her heirs and representatives.

      Section 5.11 AFFILIATES. Prior to the later of (x) the 30th day after the
date of this Agreement and (y) the 15th day after the record date for the
Interstate Stockholders Meeting, (i) Interstate shall deliver to MeriStar a

under Rule 145 of the Securities Act as of the record date for the Interstate
Stockholders Meeting, including, without limitation, all of its directors and
executive officers; and (ii) Interstate shall advise the persons identified in
such letter ("RULE 145 AFFILIATES") of the resale restrictions imposed by
applicable securities Laws and shall use its reasonable best efforts to obtain
from each person identified in such letter a written agreement, substantially in
the form of Annex I to this Agreement (a "RULE 145 AFFILIATE AGREEMENT" ).
Notwithstanding anything to the contrary contained in this Agreement, the
Surviving Corporation shall be entitled to withhold, or to instruct the Exchange
Agent to withhold, certificates representing Surviving Corporation Common Stock
to be received by any such stockholder, until such time as MeriStar or the
Surviving Corporation has received a duly executed and delivered Rule 145
Affiliate Agreement from such Rule 145 Affiliate.

      Section 5.12 REASONABLE BEST EFFORTS. Subject to the terms and conditions
provided in this Agreement and to applicable legal requirements, each of the
parties to this Agreement agrees to use its reasonable best efforts consistent
with the duties under applicable Laws of the Board of Directors of such party to
take, or cause to be taken, all actions, and to do, or cause to be done, and to
assist and cooperate with the other parties to this Agreement in doing, as
promptly as practicable, all things necessary, proper or advisable to ensure
that the conditions set forth in Article VI are satisfied and to consummate and
make effective the transactions contemplated by this Agreement. If at any time
after the Effective Time, any further action is necessary or desirable to carry
out the purposes of this Agreement, including without limitation, the execution
of additional instruments, the proper officers and directors of each party to
this Agreement shall take all such necessary action. Nothing contained in this

control or direct the other party's operations prior to the Effective Time.

      Section 5.13 CONSENTS; FILINGS; FURTHER ACTION.

            (a) Without limiting the generality of Section 5.12 hereof, subject

Agreement shall use its reasonable best efforts to (i) obtain any consent,
license, approval, authorization or permit of, waiver by, or order of, make any
filing with, and provide any notification to, any Governmental Entity that is
required to be obtained or made by MeriStar or Interstate or any of their
subsidiaries in connection with the authorization, execution and delivery of
this Agreement and


                                       70
<Page>

the consummation of the Merger and the other transactions contemplated by this
Agreement, (ii) make all necessary filings, and thereafter make any other
submissions either required or deemed appropriate by each of the parties, with
respect to this Agreement and the Merger and the other transactions contemplated
by this Agreement required under (A) the Securities Act, the Exchange Act and
any other applicable federal or Blue Sky Laws, (B) the HSR Act, (C) the DGCL,
(D) the MGCL, (E) any other applicable Law, (F) the rules and regulations of the
NYSE, and (G) the rules and regulations of the NASDAQ. The parties to this
Agreement shall cooperate and consult with each other in connection with the
making of all such filings, including by providing copies of all such documents
(other than any filings under the HSR Act) to the nonfiling party and its
advisors prior to filing, and none of the parties will file any such document if
any of the other parties shall have reasonably objected to the filing of such
document unless such filing is required by applicable Law. No party to this
Agreement shall consent to any voluntary extension of any statutory deadline or
waiting period or to any voluntary delay of the consummation of the Merger and
the other transactions contemplated by this Agreement at the behest of any
Governmental Entity without the consent and agreement of the other parties to
this Agreement, which consent shall not be unreasonably withheld or delayed.

            (b) Without limiting the generality of Section 5.12 hereof, each
party to this Agreement shall promptly inform the others of any material
communication from the Federal Trade Commission, the Department of Justice or
any other domestic or foreign government or governmental or multinational
authority regarding any of the transactions contemplated by this Agreement. If
any party or any affiliate thereof receives a request for additional information
or documentary material from any such government or authority with respect to
the transactions contemplated by this Agreement, then such party shall endeavor
in good faith to make, or cause to be made, as soon as reasonably practicable,
an appropriate response in compliance with such request. Each party shall advise
the other parties promptly in respect of any understandings, undertakings or
agreements (oral or written) which such party proposes to make or enter into
with the Federal Trade Commission, the Department of Justice or any other
domestic or foreign government or governmental or multinational authority in
connection with the transactions contemplated by this Agreement. In furtherance
and not in limitation of the foregoing, each party shall use its reasonable best
efforts to resolve such objections, if any, as may be asserted with respect to
the transactions contemplated by this Agreement under any antitrust, competition
or trade regulatory Laws, rules or regulations of any domestic or foreign
government or governmental authority or any multinational authority.
Notwithstanding the foregoing, nothing in this Section 5.13 shall require, or be
construed to require, MeriStar or Interstate, in connection with the receipt of
any regulatory approval, to proffer to, or agree to (A) sell or hold separate
and agree to sell, divest or to discontinue or limit, before or after the
Effective Time, any assets, businesses, or interest in any assets or businesses
of MeriStar, Interstate or the Surviving Corporation or any of their respective
affiliates (or to consent to any sale, or agreement to sell, or discontinuance
or limitation by MeriStar or Interstate, as the case may be, of any of its
assets or businesses) or (B) agree to any conditions relating to, or changes or
restriction in, the operations of any such asset or businesses which, in either
case, could reasonably be expected to result in a Material Adverse Effect on
MeriStar, a Material Adverse Effect on Interstate, a Material Adverse Effect on
the Surviving Corporation or to materially and adversely impact the economic or
business benefits to such party of the transactions contemplated by this
Agreement.

date of this Agreement and until the Effective Time, each party to this
Agreement shall use its reasonable best efforts to cause the Merger to qualify,
and shall not, without the prior written consent of the parties to this
Agreement, knowingly take any actions or cause any actions to be taken which
could prevent the Merger from qualifying, as a reorganization under the
provisions of Section 368(a) of the Code. Following the Effective Time, and
consistent with any such consent, none of the Surviving Corporation, or any of
its affiliates shall knowingly take any action or knowingly cause any action to
be taken which would cause the Merger to fail to so qualify as a reorganization
under Section 368(a) of the Code.

make any such public statement prior to such consultation, except to the extent

other parties before issuing any such release or making any such public
statement.

use their reasonable best efforts to cause the Surviving Corporation to cause
the Interstate Class A Common Stock to be de-listed from the NASDAQ and the
Interstate Common Stock to be de-registered under the Exchange Act as soon as
practicable following the Effective Time.

      Section 5.17 TAKEOVER STATUTES. If any Takeover Statute is or may become
applicable to the Merger or the other transactions contemplated by this
Agreement, each of MeriStar and Interstate and its respective board of directors
shall grant such approvals and take such other actions as are necessary so that
such transactions may be consummated as promptly as practicable on the terms
contemplated by this Agreement and otherwise act to eliminate or minimize the
effects of such statute or regulation on such transactions.

      Section 5.18 DIVIDENDS. Interstate and MeriStar shall coordinate with each
other with respect to the declaration, setting of record dates and payment dates
of dividends on Interstate Common Stock and MeriStar Common Stock and Surviving
Corporation Common Stock so that holders of Interstate Common Stock do not
receive dividends on Interstate Common Stock and the Surviving Corporation
Common Stock received in the Merger in respect of any calendar quarter or fail
to receive a dividend on either Interstate Common Stock or the Surviving
Corporation Common Stock received in the Merger in respect of any calendar
quarter and so that holders of MeriStar Common Stock do not receive dividends
more than one time in respect of any calendar quarter.

consent of MeriStar, the Board of Directors of Interstate shall not (a) amend

      Section 5.21 NYSE LISTING CRITERIA COMPLIANCE.

            (a) Prior to the Effective Time, MeriStar may take such actions as
may be reasonably required in order to maintain compliance with the continued
listing criteria contained in Paragraph 802 of the New York Stock Exchange
Listed Company Manual (the "NYSE CONTINUED LISTING CRITERIA") with the prior
written consent of Interstate, such consent not to be unreasonably withheld or
delayed; PROVIDED, HOWEVER, that MeriStar shall be permitted to engage in a
reverse split of the MeriStar Common Stock or combination of the MeriStar Common
Stock in order to comply with the NYSE Continued Listing Criteria without the
consent of Interstate, so long as appropriate adjustments to the Exchange Ratio
are made pursuant to Section 2.1(c) hereof.

            (b) MeriStar may also include, as a proposal to be voted upon at the
MeriStar Stockholders Meeting, a proposal to amend its certificate of

Corporation Common Stock or combination of the Surviving Corporation Common
Stock in order to comply with the NYSE Continued Listing Criteria.

      Section 5.22 RULE 16B-3 APPROVALS. The Board of Directors or Compensation

this Agreement by action taken by or on behalf of their respective Boards of
Directors at any time prior to the Effective Time; provided that, after the

deemed severable and the invalidity or unenforceability of any provision shall
not affect the validity or enforceability or the other provisions of this
Agreement. If any provision of this Agreement, or the application of that
provision to any person or any circumstance, is invalid or unenforceable, (a) a
suitable and equitable provision shall be substituted for that provision in
order to carry out, so far as may be valid and enforceable, the intent and
purpose of the invalid or unenforceable provision and (b) the remainder of this

invalidity or unenforceability affect the validity or enforceability of the
provision, or the application of that provision, in any other jurisdiction.

                                    RECITALS:

      A. MeriStar and Interstate Hotels Corporation, a Maryland corporation (the
"COMPANY" or "INTERSTATE"), propose to enter into an Agreement and Plan of
Merger, dated as of the date hereof (the "MERGER AGREEMENT"), pursuant to which
the Company will be merged with and into MeriStar on the terms and subject to

corporation in the Merger. Except as otherwise defined herein, capitalized terms
used herein shall have the respective meanings ascribed thereto in the Merger
Agreement.

      B. As of the date hereof, except as set forth on Schedule A, each
Stockholder beneficially owns and is entitled to (i) dispose of (or to direct

name on Schedule A hereto (such Series B Shares, together with any other
securities other than Notes (as defined below) issued by the Company, the
beneficial ownership of which is acquired by such Stockholder during the period
from and including the date hereof through and including the date on which this
Agreement is terminated pursuant to Section 5.2 hereof, are collectively
referred to herein as such Stockholder's "SUBJECT SHARES") and/or (ii) dispose
of (or to direct the disposition of) and, subject to any limitations imposed by
the terms of such securities, to convert (or to direct the conversion of) 8.75%
Subordinated Convertible Notes of the Company (the "NOTES") in the principal

Notes, together with any other Notes, the beneficial ownership of which is

hereof through and including the date on which this Agreement is terminated
pursuant to Section 5.2 hereof, are referred to as such Stockholder's "SUBJECT
NOTES"). The Subject Notes and the Subject Shares are collectively referred to
as such Stockholder's "SUBJECT SECURITIES". Set forth on Schedule A to this
Agreement is (i) the "Applicable Conversion Rate" (as defined in the Articles
Supplementary to the Charter of Interstate Designating the Series B Shares) for
the Series B Shares and (ii) the "Conversion Price" (as defined in the Notes)
for the Notes, each as in effect on the date hereof.

      C. As a condition and inducement to its willingness to enter into the
Merger Agreement, MeriStar has requested that each Stockholder agree, and each
Stockholder has agreed, to enter into this Agreement.

warranties and covenants contained in this Agreement, and for other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto hereby agree as follows:


<Page>

                          I. VOTING OF SUBJECT SHARES

      1.1 AGREEMENT TO VOTE SUBJECT SHARES. From the date hereof until this
Agreement is terminated pursuant to Section 5.2 hereof, at any meeting of the
stockholders of the Company called to consider and vote upon the adoption of the
Merger Agreement (and at any and all postponements and adjournments thereof)
(the "INTERSTATE STOCKHOLDERS MEETING"), and in connection with any action to be
taken in respect of the adoption of the Merger Agreement by written consent of
the stockholders of the Company, each Stockholder will vote or cause to be voted
(including by written consent, if applicable) all of such Stockholder's Subject
Shares which it has the right to vote in favor of the adoption of the Merger
Agreement and in favor of the Interstate Proposals and any other matter
necessary or appropriate for the consummation of the transactions relating to
the Merger contemplated by the Merger Agreement that is considered and voted
upon at any such meeting or made the subject of any such written consent, as
applicable. At any meeting of the stockholders of the Company called to consider
and vote upon any Adverse Proposal (and at any and all postponements and
adjournments thereof), and in connection with any action to be taken in respect
of any Adverse Proposal by written consent of the stockholders of the Company,
each Stockholder will vote or cause to be voted (including by written consent,
if applicable) all of such Stockholder's Subject Shares which it has the right
to vote against the adoption of such Adverse Proposal. For purposes of this
Agreement, the term "ADVERSE PROPOSAL" means any (a) Interstate Acquisition
Proposal that is not a Interstate Superior Proposal, (b) proposal or action that
could reasonably be expected to result in a breach of any covenant, agreement,
representation or warranty of the Company set forth in the Merger Agreement, or
(c) the following actions (other than the Merger, the other transactions
contemplated by the Merger Agreement and any other action the approval of which
has been recommended by the board of directors of the Company): (i) any
extraordinary corporate transaction, such as a merger, consolidation or other
business combination involving the Company or any Interstate Subsidiary; (ii) a
sale, lease or transfer of a material amount of assets of the Company or any
Interstate Subsidiary, or a reorganization, recapitalization, dissolution or
liquidation of the Company or any Interstate Subsidiary; (iii) (1) any change in
a majority of the persons who constitute the board of directors of the Company
as of the date hereof; (2) any change in the present capitalization of the
Company or any amendment of the Company's charter or bylaws, as amended to date;
(3) any other material change in the Company's corporate structure or business;
or (4) any other action that is intended, or could reasonably be expected, to
impede, interfere with, delay, postpone, or adversely affect the Merger and the
other transactions contemplated by this Agreement and the Merger Agreement or
increase the likelihood that such transactions will not be consummated.

      1.2 IRREVOCABLE PROXY. (a) (a) GRANT OF PROXY. Each Stockholder hereby
appoints MeriStar and any designee of MeriStar, each of them individually, as of
the record date for the Interstate Stockholders Meeting, as such Stockholder's
proxy and attorney-in-fact, with full power of substitution and resubstitution,
to vote or act by written consent with respect to all of such Stockholder's
Subject Shares which it has the right to vote (i) in accordance with Section 1.1
hereof and (ii) to sign its name (as a stockholder) to any consent, certificate
or other document relating to the Company that the law of the State of Maryland
may permit or require in connection with any matter referred to in Section 1.1
hereof. This proxy is given to secure the performance of the duties of such
Stockholder under this Agreement and its existence will not be deemed to relieve
the Stockholders of their obligations under Section 1.1 hereof. Each Stockholder
affirms that this proxy is coupled with an interest and is irrevocable until
termination of this Agreement pursuant to Section 5.2 hereof, whereupon such
proxy and power of attorney shall automatically terminate. Each Stockholder will


                                       2
<Page>

take such further action or execute such other instruments as may be necessary
to effectuate the intent of this proxy. For Subject Shares as to which the
Stockholder is the beneficial but not the record owner, the Stockholder will
cause any record owner of such Subject Shares to grant to MeriStar a proxy to
the same effect as that contained herein.

            (b) OTHER PROXIES REVOKED. Each Stockholder represents that any
proxy heretofore given in respect of such Stockholder's Subject Shares is not
irrevocable (or if irrevocable, such Stockholder will have secured the
termination of such proxy on or prior to the record date for the Interstate
Stockholders Meeting), and hereby revokes any and all such proxies, such
revocation to be effective on the record date for the Interstate Stockholders
Meeting.

      1.3 CONSENT TO THE MERGER AGREEMENT AND POST-MERGER USE OF PROCEEDS. Each
Stockholder hereby consents to the Merger, the Merger Agreement and the
consummation of the transactions contemplated thereby and by this Agreement.
Each Stockholder hereby acknowledges and agrees that, following the Effective
Time, there shall be no restriction or limitation on the use of the proceeds by
MeriStar and its subsidiaries from the issuances of the Series B Shares or the
Notes.

                          II. CONVERSION OF SECURITIES

      2.1 AGREEMENT TO CONVERT SUBJECT SECURITIES. Unless this Agreement is
terminated pursuant to Section 5.2 hereof, each Stockholder will convert or
cause to be converted all of such Stockholder's Subject Securities into
Interstate Class A Common Stock on or prior to the record date for the
Interstate Stockholders' Meeting in a manner consistent with that certain
Conversion Incentive Agreement by and between the Company and CGLH Partners I LP
and CGLH Partners II LP each, a Delaware limited partnership (the "INVESTOR
STOCKHOLDERS"), and the Company shall deliver to the Stockholder certificates
representing the number of validly issued, fully paid and nonassessable shares
of Class A Common Stock equal to (i) in the case of such Stockholder's Subject
Shares, the product obtained by multiplying the Applicable Conversion Rate for
the Series B shares (as such term is defined in Articles Supplementary to the
Charter of Interstate Designating the Series B Shares) by the number of Series B
Shares being converted, and (ii) in the case of such Stockholder's Subject
Notes, the quotient of the principal amount of Subject Notes to be converted
divided by the Conversion Price (as such term is defined in the Notes), provided
that, to the extent that conversion by such Stockholder of all of such
Stockholder's Subject Securities is restricted by the Conversion Restrictions
(as defined in Section 3.1(a)), such Stockholder will convert or cause to be
converted the greatest quantity of such Subject Securities as does not result in
a breach of such restrictions.

      2.2 RIGHT NOT TO CONVERT. Notwithstanding anything in Section 2.1 to the
contrary, each Stockholder shall have the right but not the obligation (the
"NON-CONVERSION RIGHT") not to convert such Stockholders' Subject Securities on
or prior to the record date for the Interstate Stockholders Meeting if, on such
record date there shall exist, in the reasonable opinion of a majority of such
Stockholders, a Record Date Failure. As used in this Agreement, the term "RECORD
DATE FAILURE" shall mean the failure to be satisfied of any of the conditions
set forth in Section 6.1(e), Section 6.2(c), or Section 6.3(a), (c) or (f) of
the Merger Agreement, PROVIDED, HOWEVER, that (i) any reference in such
conditions to the "Closing Date" shall be read as a reference to the record date
for the Interstate Stockholders Meeting, and (ii) any requirement for the
receipt by any party of a certificate signed by any party shall be read out of
such condition.


                                       3
<Page>

      2.3 CONVERSION FOLLOWING MERGER OF OUTSTANDING SUBJECT SECURITIES. Each
Stockholder agrees that, as contemplated by Section 4.1(d) of the Notes and
Section 7(c) of the Articles Supplementary to the Charter of Interstate
Designating the Series B Shares, (i) each of such Stockholder's Subject
Securities outstanding immediately prior to the Effective Time (other than those
that are Interstate Common Stock) shall be converted, immediately following the
Effective Time, into that number of shares of Surviving Corporation Common
Stock, associated MeriStar Rights and cash lieu of fractional shares, if any, as
such Stockholder would have received upon exchange of such Subject Securities in
the Merger had such Subject Securities been converted in accordance with their
terms into shares of Interstate Common Stock immediately prior to the Merger if
such conversion had been permitted pursuant to the terms of such securities and
(ii) each of such Stockholder's Subject Securities outstanding immediately prior
to the Effective Time that are shares of Interstate Common Stock shall be
exchanged in the Merger as provided for in the Merger Agreement.

                       III. REPRESENTATIONS AND WARRANTIES

      3.1 CERTAIN REPRESENTATIONS AND WARRANTIES OF THE STOCKHOLDERS. Each
Stockholder, severally and not jointly, represents and warrants to MeriStar, as

of termination, amendment, cancellation, notice or acceleration under, (i) if
applicable, such Stockholder's partnership agreement or similar constitutive
documents, (ii) any contract, commitment, agreement, understanding, arrangement
or restriction of any kind to which such Stockholder is a party or by which the

<Page>

            (c) NO CONFLICTS. Neither the execution and delivery of this
Agreement nor the performance by MeriStar of its obligations hereunder will
conflict with, result in a violation or breach of, or constitute a default (or

immediate family, a family trust of such Stockholder, a charitable institution
or Related Transferee of such Stockholder (as such term is defined in that
certain Investor Agreement between the Company and certain of the Stockholders,

pursuant to Section 5.6 hereof; (b) except pursuant to the terms of this
Agreement, grant any proxies or powers of attorney with respect to any Subject
Securities, deposit any Subject Securities into a voting trust or enter into a
voting agreement with respect to any Subject Securities; or (c) take any action

warranties contained herein untrue or incorrect or have the effect of impairing

capital stock or other securities of the Company on, of or affecting the Subject
Securities or any other similar action that would have the effect of changing a
Stockholder's ownership of Subject Securities or (ii) a Stockholder becomes the
beneficial owner of any additional Subject Securities, then the terms of this
Agreement will apply to the Subject Securities held by such Stockholder
immediately following the effectiveness of the events described in clause (i) or
such Stockholder becoming the beneficial owner thereof, as described in clause
(ii).

the Company in connection with their respective reasonable best efforts to

<Page>

the Merger Agreement. This Agreement may be earlier terminated by the mutual
consent of the MeriStar and the Stockholders representing a majority of the
Subject Securities subject to this Agreement. Except as set forth below, in the
event of termination of this Agreement pursuant to this Section 5.2, this
Agreement will become null and void and of no effect with no liability on the
part of any party hereto and all proxies granted hereby will be automatically
revoked; provided, however, that no such termination will relieve any party
hereto from any liability for any breach of this Agreement occurring prior to
such termination.

      Notwithstanding anything to the contrary contained in this Agreement, if
this Agreement is terminated for any reason, Sections 3.1(a), 3.1(b), 5.1, 5.5
and 5.15 hereof and the preceding sentence of this Section 5.2 will survive any
termination of this Agreement indefinitely.

      5.3 EXTENSION; WAIVER. Any agreement on the part of a party to waive any
provision of this Agreement, or to extend the time for any performance
hereunder, will be valid only if set forth in an instrument in writing signed on
behalf of such party. The failure of any party to this Agreement to assert any
of its rights under this Agreement or otherwise will not constitute a waiver of
such rights. Any waiver by any party of a breach of any provision of this
Agreement will not operate as or be construed as a waiver of any other breach of
such provision or of any breach of any other provision of this Agreement. The
failure of a party to insist upon strict adherence to any term of this Agreement
or one or more sections hereof will not be considered a waiver or deprive that
party of a right thereafter to insist upon strict adherence to that term or any
other term of this Agreement.

      5.4 ENTIRE AGREEMENT; NO THIRD-PARTY BENEFICIARIES; SEVERAL OBLIGATIONS.
This Agreement and the Merger Agreement constitute the entire agreement among
the parties hereto with respect to the subject matter hereof, and supersede all
prior agreements and understandings, both written and oral, among the parties
with respect to such matters. Neither the Merger Agreement nor this Agreement is
intended to confer upon any Person other than the parties hereto any rights or
remedies. The obligations of, and the representations and warranties made by,
each Stockholder shall be several and not joint and shall relate only to such
Stockholder.

      5.5 GOVERNING LAW; WAIVER OF JURY TRIAL. (a) (A) THIS AGREEMENT SHALL BE
DEEMED TO BE MADE IN AND IN ALL RESPECTS SHALL BE INTERPRETED, CONSTRUED AND
GOVERNED BY AND IN ACCORDANCE WITH THE LAW OF THE STATE OF DELAWARE WITHOUT
REGARD TO CONFLICT OF LAW PRINCIPLES.

            (b) Each party acknowledges and agrees that any controversy which
may arise under this Agreement is likely to involve complicated and difficult
issues, and therefore each such party hereby irrevocably and unconditionally
waives any right such party may have to a trial by jury in respect of any
litigation directly or indirectly arising out of or relating to this Agreement,
or the transactions contemplated by this agreement. Each party certifies and
acknowledges that (i) no representative, agent or attorney of any other party
has represented, expressly or otherwise, that such other party would not, in the
event of litigation, seek to enforce the foregoing waiver, (ii) each such party
understands and has considered the implications of this waiver, (iii) each such
party makes this waiver voluntarily, and (iv) each such party has been induced
to enter into this agreement by, among


                                       8

other things, the mutual waivers and certifications in this Section 5.5(b).

or to such other persons or addresses as may be designated in writing by the

      5.7 ASSIGNMENT. Neither this Agreement nor any of the rights, interests,
or obligations under this Agreement may be assigned or delegated, in whole or in
part, by operation of law or otherwise, by any Stockholder without the prior
written consent of MeriStar or by MeriStar without the consent of the applicable
Stockholder (and then only with respect to such Stockholder), and any such
assignment or delegation that is not consented to will be null and void;
PROVIDED that this Agreement, together with any rights, interests, or
obligations of MeriStar hereunder, may be assigned or delegated, in whole or in
part, by MeriStar to any direct or indirect wholly owned subsidiary of MeriStar
without the consent of or any action by any Stockholder upon notice by MeriStar
to each Stockholder affected thereby as herein provided; PROVIDED FURTHER,
HOWEVER, that any such assignment shall not relieve MeriStar of its obligations
hereunder. Subject to the preceding sentence, this Agreement will be binding
upon, inure to the benefit of, and be enforceable by, the parties and their
respective successors and assigns (including, without limitation, any Person to
whom any Subject Securities are sold, transferred or assigned).

      5.8 FURTHER ASSURANCES. Each Stockholder will execute and deliver such
other documents and instruments and take such further actions as may be
necessary or appropriate or as may be reasonably requested by MeriStar in order
to ensure that MeriStar receives the full benefit of this Agreement.

      5.9 PUBLICITY. MeriStar and each Stockholder will reasonably consult with
each other party and with the Company before issuing any press release or
otherwise making any public statements with respect to this Agreement and will
not issue any such press release or make any such public statement before such
consultation, except as may be required by Law or applicable stock exchange


                                       10
<Page>

rules.

      5.10 ENFORCEMENT. Irreparable damage would occur in the event that any of
the provisions of this Agreement were not performed in accordance with their
specific terms or were otherwise breached. Accordingly, the parties will be
entitled to an injunction or injunctions to prevent breaches of this Agreement
and to enforce specifically the terms and provisions of this Agreement, this
being in addition to any other remedy to which they are entitled at law or in
equity.

      5.11 SEVERABILITY. The provisions of this Agreement shall be deemed
severable and the invalidity or unenforceability of any provision shall not
affect the validity or enforceability or the other provisions of this Agreement.
If any provision of this Agreement, or the application of that provision to any
person or any circumstance, is invalid or unenforceable, (a) a suitable and
equitable provision shall be substituted for that provision in order to carry
out, so far as may be valid and enforceable, the intent and purpose of the
invalid or unenforceable provision and (b) the remainder of this Agreement and
the application of the 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 the provision, or the
application of that provision, in any other jurisdiction.

      5.12 COUNTERPARTS. This Agreement may be executed in any number of
counterparts, each such counterpart being deemed to be an original instrument,
and all such counterparts shall together constitute the same agreement.

      5.13 HEADINGS. The descriptive headings contained herein are for
convenience and reference only and will not affect in any way the meaning or
interpretation of this Agreement.

      5.14 REMEDIES NOT EXCLUSIVE. All rights, powers and remedies provided
under this Agreement or otherwise available in respect hereof at law or in
equity will be cumulative and not alternative, and the exercise of any thereof
by either party will not preclude the simultaneous or later exercise of any
other such right, power or remedy by such party.

      5.15 JURISDICTION; CONSENT TO SERVICE OF PROCESS. (a) (a) Each party
hereto hereby irrevocably and unconditionally submits, for itself and its
property, to the exclusive jurisdiction of the Chancery or other courts of the
State of Delaware (a "DELAWARE COURT"), and any appellate court from any such
court, in any suit, action or proceeding arising out of or relating to this
Agreement, or for recognition or enforcement of any judgment resulting from any
suit, action or proceeding, and each party hereby irrevocably and
unconditionally agrees that all claims in respect of any such suit, action or
proceeding may be heard and determined in a Delaware Court.

            (b) It will be a condition precedent to each party's right to bring
any such suit, action or proceeding that such suit, action or proceeding, in the
first instance, be brought in a Delaware Court (unless such suit, action or
proceeding is brought solely to obtain discovery or to enforce a judgment), and
if each such court refuses to accept jurisdiction with respect thereto, such
suit, action or proceeding may be brought in any other court with jurisdiction.

            (c) No party may move to (i) transfer any such suit, action or
proceeding from a Delaware Court to another jurisdiction, (ii) consolidate any
such suit, action or proceeding brought in a Delaware Court with a suit, action
or proceeding in another jurisdiction, or (iii) dismiss any such suit, action or
proceeding brought in a Delaware Court for the purpose of bringing the same in
another


                                       11
<Page>

jurisdiction.

            (d) Each party hereby irrevocably and unconditionally waives, to the
fullest extent it may legally and effectively do so, (i) any objection which it
may now or hereafter have to the laying of venue of any suit, action or
proceeding arising out of or relating to this Agreement in a Delaware Court,
(ii) the defense of an inconvenient forum to the maintenance of such suit,
action or proceeding in any such court, and (iii) the right to object, with
respect to such suit, action or proceeding, that such court does not have
jurisdiction over such party. Each party irrevocably consents to service of
process in any manner permitted by law.

      5.16 FIDUCIARY DUTIES. Each Stockholder is signing this Agreement solely
in such Stockholder's capacity as the beneficial owner of Subject Securities
and, notwithstanding anything herein to the contrary, nothing contained herein
shall limit or affect any actions taken by such Stockholder or any designee of
such Stockholder in his or her capacity, if any, as an officer or director of
the Company or any of its Subsidiaries and none of such actions in any such
capacity shall be deemed to constitute a breach of this Agreement.

      5.17 BENEFICIAL OWNERSHIP. For purposes of this Agreement, the term
"beneficial owner" shall have the meaning ascribed to such term under Rule 13d-3
under the Securities Exchange Act of 1934, and the terms "beneficially own" and
"beneficial ownership" shall have correlative meanings therewith.

The following is the MeriStar Hotels & Resorts, Inc. Stockholder Voting
Agreement, dated as of May 1, 2002, among Interstate Hotels Corporation and the
persons set forth on Schedule A thereto

                         MERISTAR HOTELS & RESORTS, INC.
                          STOCKHOLDER VOTING AGREEMENT

      VOTING AGREEMENT, dated as of May 1, 2002 (this "AGREEMENT"), among
Interstate Hotels Corporation, a Maryland corporation ("INTERSTATE"), and each
of the persons set forth on Schedule A hereto (each, a "STOCKHOLDER" and,
collectively, the "STOCKHOLDERS").

                                    RECITALS:

      A. Interstate and Meristar Hotels & Resorts, Inc., a Delaware corporation
("MERISTAR") propose to enter into an Agreement and Plan of Merger, dated as of
the date hereof (the "MERGER AGREEMENT"), pursuant to which Interstate will be
merged with and into MeriStar on the terms and subject to the conditions set
forth in the Merger Agreement. MeriStar will be the surviving corporation in the
Merger. Except as otherwise defined herein, capitalized terms used herein shall
have the respective meanings ascribed thereto in the Merger Agreement.

      B. As of the date hereof, each Stockholder beneficially owns and is
entitled to dispose of (or to direct the disposition of) and to vote (or to
direct the voting of) the number of shares of MeriStar Common Stock set forth
opposite such Stockholder's name on Schedule A hereto (such shares together with
any other shares of MeriStar Common Stock, the beneficial ownership of which is
acquired by such Stockholder during the period from and including the date
hereof through and including the date on which this Agreement is terminated
pursuant to Section 4.2 hereof, are collectively referred to herein as such
Stockholder's "SUBJECT SHARES").

      C. As a condition and inducement to their willingness to enter into the
Merger Agreement, Interstate has requested that each Stockholder agree, and each
Stockholder has agreed, to enter into this Agreement.

      NOW, THEREFORE, in consideration of the foregoing and the representations,
warranties and covenants contained in this Agreement, and for other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto hereby agree as follow:

                          I. VOTING OF SUBJECT SHARES

      1.1 AGREEMENT TO VOTE SUBJECT SHARES. From the date hereof until this
Agreement is terminated pursuant to Section 4.2 hereof, at any meeting of the
stockholders of MeriStar called to consider and vote upon the adoption of the
Merger Agreement (and at any and all postponements and adjournments thereof),
and in connection with any action to be taken in respect of the adoption of the
Merger Agreement by written consent of the stockholders of MeriStar, each
Stockholder will vote or cause to be voted (including by written consent, if
applicable) all of such Stockholder's Subject Shares which it has the right to
vote in favor of the adoption of the Merger Agreement and in favor of the
MeriStar Proposals and any other matter necessary or appropriate for the
consummation of the transactions relating to the Merger contemplated by the
Merger Agreement that is considered and voted upon at any such meeting or made
the subject of any such written consent, as applicable. At any meeting of the
stockholders of MeriStar called to consider and vote


<Page>

upon any Adverse Proposal (and at any and all postponements and adjournments
thereof), and in connection with any action to be taken in respect of any
Adverse Proposal by written consent of the stockholders of MeriStar, each
Stockholder will vote or cause to be voted (including by written consent, if
applicable) all of such Stockholder's Subject Shares which it has the right to
vote against the adoption of such Adverse Proposal. For purposes of this
Agreement, the term "ADVERSE PROPOSAL" means any (a) MeriStar Acquisition
Proposal that is not a MeriStar Superior Proposal, (b) proposal or action that
could reasonably be expected to result in a breach of any covenant, agreement,
representation or warranty of MeriStar set forth in the Merger Agreement, or (c)
the following actions (other than the Merger, the other transactions
contemplated by the Merger Agreement and any other action the approval of which
has been recommended by the board of directors of MeriStar): (i) any
extraordinary corporate transaction, such as a merger, consolidation or other
business combination involving MeriStar or any MeriStar Subsidiary; (ii) a sale,
lease or transfer of a material amount of assets of MeriStar or any MeriStar
Subsidiary, or a reorganization, recapitalization, dissolution or liquidation of
MeriStar or any MeriStar Subsidiary; (iii) (1) any change in a majority of the
persons who constitute the board of directors of MeriStar as of the date hereof;
(2) any change in the present capitalization of MeriStar or any amendment of
MeriStar's certificate of incorporation or bylaws, as amended to date; (3) any
other material change in MeriStar's corporate structure or business; or (4) any
other action that is intended, or could reasonably be expected, to impede,
interfere with, delay, postpone, or adversely affect the Merger and the other
transactions contemplated by this Agreement and the Merger Agreement or increase
the likelihood that such transactions will not be consummated.

      1.2 IRREVOCABLE PROXY. (a) (a) GRANT OF PROXY. Each Stockholder hereby
appoints Interstate and any designee of Interstate, each of them individually,
as such Stockholder's proxy and attorney-in-fact, with full power of
substitution and resubstitution, to vote or act by written consent with respect
to all of such Stockholder's Subject Shares which it has the right to vote (i)
in accordance with Section 1.1 hereof and (ii) to sign its name (as a
stockholder) to any consent, certificate or other document relating to MeriStar
that the law of the State of Delaware may permit or require in connection with
any matter referred to in Section 1.1 hereof. This proxy is given to secure the
performance of the duties of such Stockholder under this Agreement and its
existence will not be deemed to relieve the Stockholders of their obligations
under Section 1.1 hereof. Each Stockholder affirms that this proxy is coupled
with an interest and is irrevocable until termination of this Agreement pursuant
to Section 4.2 hereof, whereupon such proxy and power of attorney shall
automatically terminate. Each Stockholder will take such further action or
execute such other instruments as may be necessary to effectuate the intent of
this proxy. For Subject Shares as to which the Stockholder is the beneficial but
not the record owner, the Stockholder will cause any record owner of such
Subject Shares to grant to Interstate a proxy to the same effect as that
contained herein.

            (b) OTHER PROXIES REVOKED. Each Stockholder represents that any
proxy heretofore given in respect of such Stockholder's Subject Shares is not
irrevocable, and is hereby revoked.

                       II. REPRESENTATIONS AND WARRANTIES

      2.1 CERTAIN REPRESENTATIONS AND WARRANTIES OF THE STOCKHOLDERS. Each
Stockholder, severally and not jointly, represents and warrants to Interstate as
follows:


                                       2
<Page>

            (a) OWNERSHIP. Such Stockholder is the sole beneficial owner of the
number of Subject Shares set forth opposite such Stockholder's name on Schedule
A hereto and has full and unrestricted power to dispose of, to vote, to grant a
proxy in respect of and to convert such securities of MeriStar, as applicable.
Such Subject Shares are now, and at all times during the term hereof will be
held by such Stockholder or any Permitted Transferee (as defined in Section 4.1
hereof), or by a nominee or custodian for the benefit of such Stockholder, free
and clear of all Liens and proxies, except for any Liens or proxies arising
hereunder. Except as set forth opposite the Stockholder's name on Schedule A
hereto, such Stockholder (i) does not beneficially own any securities issued by
MeriStar on the date hereof; (ii) does not, directly or indirectly, beneficially
own or have any option, warrant or other right to acquire any shares issued by
MeriStar that are or may by their terms become entitled to vote on any matter
presented to MeriStar's Stockholders or any securities that are convertible or
exchangeable into or exercisable for any securities issued by MeriStar that are
or may by their terms become entitled to vote, or any matter presented to
MeriStar's Shareholders nor is such Stockholder subject to any contract,
commitment, arrangement, understanding or relationship (whether or not legally
enforceable), other than this Agreement, that allows or obligates such
Stockholder to vote, dispose of or acquire any securities issued by MeriStar;
and (iii) holds exclusive power to vote the Subject Shares on any matter
presented to MeriStar's stockholders in respect of which such Subject Shares are
entitled to vote or give consent and has not granted a proxy to any other Person
to vote or give consent the Subject Shares, subject to the limitations set forth
in this Agreement.

            (b) POWER AND AUTHORITY; EXECUTION AND DELIVERY. Such Stockholder
has all requisite individual power and authority to execute and deliver this
Agreement and to consummate the transactions contemplated hereby, and has taken
all necessary action to authorize the execution, delivery and performance of
this Agreement. This Agreement has been duly executed and delivered by such
Stockholder and constitutes a valid and binding obligation of such Stockholder,
enforceable against such Stockholder in accordance with its terms.

            (c) NO CONFLICTS. The execution and delivery of this Agreement do
not, and, subject to compliance with the HSR Act and appropriate filings under
securities laws (which such Stockholder agrees to make promptly), to the extent
applicable, the consummation of the transactions contemplated hereby and
compliance with the provisions hereof will not, conflict with, result in a
violation or breach of, or constitute a default (or an event that, with notice
or lapse of time or both, would result in a default) or give rise to any right
of termination, amendment, cancellation, notice or acceleration under, (i) any
contract, commitment, agreement, understanding, arrangement or restriction of
any kind to which such Stockholder is a party or by which such Stockholder is
bound, (ii) any injunction, judgment, writ, decree, order or ruling applicable
to such Stockholder or (iii) any law, statute, rule or regulation applicable to
such Stockholder; except in the case of clauses (i) and (ii) for conflicts,
violations, breaches or defaults that could not reasonably be expected to (1)
impair the ability of such Stockholder to perform its obligations under this
Agreement or (2) prevent or delay the consummation of any of the transactions
contemplated by this Agreement or the Merger Agreement.

            (d) BROKERS. Except as set forth in Section 4.19 of the Merger
Agreement, no broker, finder or investment banker is entitled to any brokerage,

            (c) NO CONFLICTS. Neither the execution and delivery of this
Agreement nor the performance by Interstate of its respective obligations
hereunder will conflict with, result in a violation or breach of, or constitute
a default (or an event that, with notice or lapse of time or both, would result
in a default) or give rise to any right of termination, amendment, cancellation,

documents, (ii) any contract, commitment, agreement, understanding, arrangement

                     III. CERTAIN COVENANTS OF STOCKHOLDERS

      3.1 RESTRICTION ON TRANSFER OF SUBJECT SHARES, PROXIES AND
NONINTERFERENCE. No Stockholder will, directly or indirectly: (a) except
pursuant to the terms of this Agreement, (i) offer for sale, sell, transfer,
tender, pledge, encumber, assign or otherwise dispose of, or (ii) enter into any
contract, option or other arrangement or understanding with respect to or (iii)
consent to the offer for sale, sale, transfer, tender, pledge, encumbrance,
assignment or other disposition of, any or all of such Stockholder's Subject
Shares other than any sale, transfer, assignment or other action restricted by
this clause 3.1(a) to members of such Stockholder's immediate family, a family
trust of such Stockholder or a charitable institution (each a "PERMITTED

with respect to any Subject Shares, deposit any Subject Shares into a voting
trust or enter into a voting agreement with respect to any Subject Shares; or
(c) take any action that could reasonably be expected to make any of its
representations or warranties contained herein untrue or incorrect or have the
effect of impairing the ability of such Stockholder to perform such
Stockholder's obligations under this Agreement or preventing or delaying the
consummation of any of the transactions contemplated by this Agreement or the
Merger Agreement.


                                       4
<Page>

      3.2 ADJUSTMENTS. (a)(a) In the event (i) of any stock dividend, stock
split, recapitalization, reclassification, combination or exchange of shares of
capital stock or other securities of MeriStar on, of or affecting the Subject
Shares or any other similar action that would have the effect of changing a
Stockholder's ownership of Subject Shares or (ii) a Stockholder becomes the
beneficial owner of any additional Subject Shares, then the terms of this
Agreement will apply to the Subject Shares held by such Stockholder immediately
following the effectiveness of the events described in clause (i) or such
Stockholder becoming the beneficial owner thereof, as described in clause (ii).

            (b) Each Stockholder hereby agrees, while this Agreement is in
effect, to promptly notify Interstate of the number of any new Subject Shares
acquired by such Stockholder, if any, after the date hereof.

      3.3 NO SOLICITATION. Subject to Section 4.16, no Stockholder will take,
authorize or permit any of its officers, directors, employees, agents or
representatives (including any investment banker, financial advisor, attorney or
accountant for such Stockholder) ("REPRESENTATIVES") to take, any action that
MeriStar would be prohibited from taking under the first sentence of Section
5.8(a) of the Merger Agreement (disregarding for purposes of this Section 3.3
the proviso to such sentence). Each Stockholder will, and will cause its
Representatives to, immediately cease all existing discussions or negotiations
with respect to any of the foregoing and promptly (and in any event within one
business day) advise Interstate in writing of the receipt by such Stockholder of
a request for information or any inquiries or proposals relating to a MeriStar
Acquisition Proposal. Notwithstanding any provision of Sections 3.3 or 3.5
hereof the contrary, (a) if any Stockholder or any of its Representatives is a
member of the Board of Directors of MeriStar, such member of the Board of
Directors of MeriStar may take actions in such capacity to the extent permitted
by Section 5.8 of the Merger Agreement, and (b) if any Stockholder is an officer
of MeriStar, such officer may take actions in such capacity to the extent
directed to do so by the Board of Directors in compliance with Section 5.8 of
the Merger Agreement.

      3.4 WAIVER OF APPRAISAL RIGHTS. Each Stockholder hereby waives any rights
of appraisal or rights to dissent from the Merger that such Stockholder may
have.

      3.5 COOPERATION. Each Stockholder will cooperate fully with MeriStar and
Interstate in connection with their respective reasonable best efforts to
fulfill the conditions to the Merger set forth in Article VI of the Merger
Agreement.

      3.6 DISCLOSURE. Each Stockholder hereby authorizes Interstate to publish
and disclose in any announcement or disclosure required by the SEC and the Proxy
Statement (including all documents and schedules filed with the SEC in
connection with either of the foregoing), its identity and ownership of the
Subject Shares and the nature of its commitments, arrangements and
understandings under this Agreement provided that such Stockholder is provided
with a reasonable opportunity to review and comment on such disclosure.

                               IV. MISCELLANEOUS

      4.1 FEES AND EXPENSES. Each party hereto will pay its own expenses
incident to preparing for, entering into and carrying out this Agreement and the
consummation of the


                                       5
<Page>

transactions contemplated hereby.

      4.2 AMENDMENT; TERMINATION. This Agreement may not be amended except by an
instrument in writing signed on behalf of Interstate and each of the parties
whose rights or obligations are changed by the terms of such amendment. This
Agreement will terminate on the earliest to occur of (a) the Effective Time or
(b) the date the Merger Agreement is terminated in accordance with its terms.
This Agreement may be earlier terminated by the mutual consent of the Board of
Directors of Interstate and the Stockholders representing a majority of the
Subject Shares subject to this Agreement. Except as set forth below, in the
event of termination of this Agreement pursuant to this Section 4.2, this
Agreement will become null and void and of no effect with no liability on the
part of any party hereto and all proxies granted hereby will be automatically
revoked; provided, however, that no such termination will relieve any party
hereto from any liability for any breach of this Agreement occurring prior to
such termination.

      Notwithstanding anything to the contrary contained in this Agreement, if
this Agreement is terminated for any reason, Sections 4.1, 4.5 and 4.15 hereof
and the preceding sentence of this Section 4.2 will survive any termination of
this Agreement indefinitely.

      4.3 EXTENSION; WAIVER. Any agreement on the part of a party to waive any
provision of this Agreement, or to extend the time for any performance
hereunder, will be valid only if set forth in an instrument in writing signed on
behalf of such party. The failure of any party to this Agreement to assert any
of its rights under this Agreement or otherwise will not constitute a waiver of
such rights. Any waiver by any party of a breach of any provision of this
Agreement will not operate as or be construed as a waiver of any other breach of
such provision or of any breach of any other provision of this Agreement. The
failure of a party to insist upon strict adherence to any term of this Agreement
or one or more sections hereof will not be considered a waiver or deprive that
party of a right thereafter to insist upon strict adherence to that term or any
other term of this Agreement.

      4.4 ENTIRE AGREEMENT; NO THIRD-PARTY BENEFICIARIES; SEVERAL OBLIGATIONS.
This Agreement and the Merger Agreement constitute the entire agreement among
the parties hereto with respect to the subject matter hereof, and supersede all
prior agreements and understandings, both written and oral, among the parties
with respect to such matters. Neither the Merger Agreement nor this Agreement is
intended to confer upon any Person other than the parties hereto any rights or
remedies. The obligations of, and the representations and warranties made by,
each Stockholder shall be several and not joint and shall relate only to such
Stockholder.

      4.5 GOVERNING LAW; WAIVER OF JURY TRIAL.(a) (a) THIS AGREEMENT SHALL BE
DEEMED TO BE MADE IN AND IN ALL RESPECTS SHALL BE INTERPRETED, CONSTRUED AND
GOVERNED BY AND IN ACCORDANCE WITH THE LAW OF THE STATE OF DELAWARE WITHOUT
REGARD TO CONFLICT OF LAW PRINCIPLES.

            (b) Each party acknowledges and agrees that any controversy which
may arise under this Agreement is likely to involve complicated and difficult
issues, and therefore each such party hereby irrevocably and unconditionally
waives any right such party may have to a trial by jury in respect of any
litigation directly or indirectly arising out of or relating to this Agreement,
or the transactions contemplated by this agreement. Each party certifies and
acknowledges that (i) no representative, agent or attorney of any other party
has represented, expressly or otherwise, that


                                       6
<Page>

such other party would not, in the event of litigation, seek to enforce the
foregoing waiver, (ii) each such party understands and has considered the
implications of this waiver, (iii) each such party makes this waiver
voluntarily, and (iv) each such party has been induced to enter into this
agreement by, among other things, the mutual waivers and certifications in this
Section 4.5(b).

      4.6 NOTICES. Any notice, request, instruction or other document to be
given hereunder by any party to the others shall be in writing and delivered

<Page>

notice as provided above.

      4.7 ASSIGNMENT. Neither this Agreement nor any of the rights, interests,
or obligations under this Agreement may be assigned or delegated, in whole or in
part, by operation of law or otherwise, by any Stockholder without the prior
written consent of Interstate or by Interstate without the consent of the
applicable Stockholder (and then only with respect to such Stockholder), and any
such assignment or delegation that is not consented to will be null and void;
PROVIDED that this Agreement, together with any rights, interests, or
obligations of Interstate hereunder, may be assigned or delegated, in whole or
in part, by Interstate to any direct or indirect wholly owned subsidiary of
Interstate without the consent of or any action by any Stockholder upon notice
by Interstate to each Stockholder affected thereby as herein provided; PROVIDED
FURTHER, HOWEVER, that any such assignment shall not relieve MeriStar of its
obligations hereunder. Subject to the preceding sentence, this Agreement will be
binding upon, inure to the benefit of, and be enforceable by, the parties and
their respective successors and assigns (including, without limitation, any
Person to whom any Subject Shares are sold, transferred or assigned).

      4.8 FURTHER ASSURANCES. Each Stockholder will execute and deliver such
other documents and instruments and take such further actions as may be
necessary or appropriate or as may be reasonably requested by Interstate in
order to ensure that Interstate receive the full benefit of this Agreement.

      4.9 PUBLICITY. Except as may be required by Law or applicable stock
exchange rules, MeriStar, Interstate, and each Stockholder will reasonably
consult with each other party before issuing any press release or otherwise
making any public statements with respect to this Agreement and will not issue
any such press release or make any such public statement before such
consultation.

      4.10 ENFORCEMENT. Irreparable damage would occur in the event that any of
the provisions of this Agreement were not performed in accordance with their
specific terms or were otherwise breached. Accordingly, the parties will be
entitled to an injunction or injunctions to prevent breaches of this Agreement
and to enforce specifically the terms and provisions of this Agreement, this
being in addition to any other remedy to which they are entitled at law or in
equity.

      4.11 SEVERABILITY. The provisions of this Agreement shall be deemed
severable and the invalidity or unenforceability of any provision shall not
affect the validity or enforceability or the other provisions of this Agreement.
If any provision of this Agreement, or the application of that provision to any
person or any circumstance, is invalid or unenforceable, (a) a suitable and
equitable provision shall be substituted for that provision in order to carry
out, so far as may be valid and enforceable, the intent and purpose of the
invalid or unenforceable provision and (b) the remainder of this Agreement and
the application of the 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 the provision, or the
application of that provision, in any other jurisdiction.

      4.12 COUNTERPARTS. This Agreement may be executed in any number of
counterparts, each such counterpart being deemed to be an original instrument,
and all such counterparts shall together constitute the same agreement.


                                       8

      4.13 HEADINGS. The descriptive headings contained herein are for
convenience and reference only and will not affect in any way the meaning or
interpretation of this Agreement.

      4.14 REMEDIES NOT EXCLUSIVE. All rights, powers and remedies provided
under this Agreement or otherwise available in respect hereof at law or in
equity will be cumulative and not alternative, and the exercise of any thereof
by either party will not preclude the simultaneous or later exercise of any
other such right, power or remedy by such party.

      4.15 JURISDICTION; CONSENT TO SERVICE OF PROCESS. (a)(a) Each party hereto
hereby irrevocably and unconditionally submits, for itself and its property, to
the exclusive jurisdiction of the Chancery or other courts of the State of
Delaware (a "DELAWARE COURT"), and any appellate court from any such court, in
any suit, action or proceeding arising out of or relating to this Agreement, or
for recognition or enforcement of any judgment resulting from any suit, action
or proceeding, and each party hereby irrevocably and unconditionally agrees that
all claims in respect of any such suit, action or proceeding may be heard and
determined in a Delaware Court.

            (b) It will be a condition precedent to each party's right to bring
any such suit, action or proceeding that such suit, action or proceeding, in the
first instance, be brought in a Delaware Court (unless such suit, action or
proceeding is brought solely to obtain discovery or to enforce a judgment), and
if each such court refuses to accept jurisdiction with respect thereto, such
suit, action or proceeding may be brought in any other court with jurisdiction.

            (c) No party may move to (i) transfer any such suit, action or
proceeding from a Delaware Court to another jurisdiction, (ii) consolidate any
such suit, action or proceeding brought in a Delaware Court with a suit, action
or proceeding in another jurisdiction, or (iii) dismiss any such suit, action or
proceeding brought in a Delaware Court for the purpose of bringing the same in
another jurisdiction.

            (d) Each party hereby irrevocably and unconditionally waives, to the
fullest extent it may legally and effectively do so, (i) any objection which it
may now or hereafter have to the laying of venue of any suit, action or
proceeding arising out of or relating to this Agreement in a Delaware Court,
(ii) the defense of an inconvenient forum to the maintenance of such suit,
action or proceeding in any such court, and (iii) the right to object, with
respect to such suit, action or proceeding, that such court does not have
jurisdiction over such party. Each party irrevocably consents to service of
process in any manner permitted by law.

      4.16 FIDUCIARY DUTIES. Each Stockholder is signing this Agreement solely
in such Stockholder's capacity as the beneficial owner of Subject Shares and,
notwithstanding anything herein to the contrary, nothing contained herein shall
limit or affect any actions taken by such Stockholder or any designee of such
Stockholder in his or her capacity, if any, as an officer or director of
MeriStar or any of its Subsidiaries and none of such actions in any such
capacity shall be deemed to constitute a breach of this Agreement.

      4.17 BENEFICIAL OWNERSHIP. For purposes of this Agreement, the term
"beneficial owner" shall have the meaning ascribed to such term under Rule 13d-3
under the Securities Exchange Act of 1934, and the terms "beneficially own" and
"beneficial ownership" shall have correlative meanings therewith.

      9.7. JURISDICTION; CONSENT TO SERVICE OF PROCESS.

            (a) Each party hereto hereby irrevocably and unconditionally
submits, for itself and its property, to the exclusive jurisdiction of the
Chancery or other courts of the State of Maryland (a "MARYLAND COURT"), and
any appellate court from any such court, in any suit, action or proceeding
arising out of or relating to this Agreement, or for recognition or
enforcement of any judgment resulting from any suit, action or proceeding,
and each party hereby irrevocably and unconditionally agrees that all claims
in respect of any such suit, action or proceeding may be heard and determined
in a Maryland Court.

            (b) It will be a condition precedent to each party's right to
bring any such suit, action or proceeding that such suit, action or
proceeding, in the first instance, be brought in a Maryland Court (unless
such suit, action or proceeding is brought solely to obtain discovery or to
enforce a judgment), and if each such court refuses to accept jurisdiction
with respect thereto, such suit, action or proceeding may be brought in any
other court with jurisdiction.

            (c) No party may move to (i) transfer any such suit, action or
proceeding from a Maryland Court to another jurisdiction, (ii) consolidate
any such suit, action or proceeding brought in a Maryland Court with a suit,
action or proceeding in another jurisdiction, or (iii) dismiss any such suit,
action or proceeding brought in a Maryland Court for the purpose of bringing
the same in another jurisdiction.

            (d) Each party hereby irrevocably and unconditionally waives, to
the fullest extent it may legally and effectively do so, (i) any objection
which it may now or hereafter have to the laying of venue of any suit, action
or proceeding arising out of or relating to this Agreement in a Maryland
Court, (ii) the defense of an inconvenient forum to the maintenance of such
suit, action or proceeding in any such court, and (iii) the right to object,
with respect to such suit, action or proceeding, that such court does not
have jurisdiction over such party. Each party irrevocably consents to service
of process in any manner permitted by law.

      9.8. FIDUCIARY DUTIES.

Each Security Holder is signing this Agreement solely in such Security Holder's
capacity as the beneficial owner of the Convertible Securities and,
notwithstanding anything herein to the contrary, nothing contained herein shall
limit or affect any actions taken by such Security Holder or any designee of
such Security Holder in his or her capacity, if any, as an officer or director
of the Company or any of its Subsidiaries and none of such actions in any such
capacity shall be deemed to constitute a breach of this Agreement.

      9.9. COUNTERPARTS. This Agreement may be executed in any number of
counterparts, each of which shall be an original, but all of which together
shall constitute one instrument. All signatures need not appear on any one
counterpart.

      9.10. SEVERABILITY. Any term or provision of this Agreement which is
invalid or unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such invalidity or unenforceability without
rendering invalid or unenforceable the remaining terms and provisions of this
Agreement or affecting the validity or enforceability of any of the terms or
provisions of this Agreement in any other jurisdiction.

      9.11. SPECIFIC PERFORMANCE. The parties hereto acknowledge that there
would be no adequate remedy at law if any party fails to perform any of its
obligations hereunder, and accordingly agree that each party, in addition to any
other remedy to which it may be entitled at law or in equity, shall be entitled
to injunctive relief, including specific performance, to enforce such
obligations without the posting of any bond, and, if any action should be
brought in equity to enforce any of the provisions of this Agreement, none of
the parties hereto shall raise the defense that there is an adequate remedy at
law.
