     This Amendment No. 1 amends and supplements the Tender Offer Statement on
Schedule TO-T ("Schedule TO-T") filed by Shaner Hotel Group Limited Partnership,
a Delaware limited partnership ("Shaner Hotel Group"), on April 3, 2002,
relating to the offer by Shaner Hotel Group to purchase 2,465,322 shares of
Class A Common Stock, $0.01 par value per share (the "Shares"), and, if
applicable, the related preferred stock purchase rights, of Interstate Hotels
Corporation, a Maryland corporation (the "Company"), at a price of $3.00 per
Share, net to the seller in cash, without interest, upon the terms and subject
to the conditions set forth in the Offer to Purchase, dated April 3, 2002
("Offer to Purchase"), and in the related Letter of Transmittal, filed as
Exhibits (a)(1) and (a)(2), respectively (which, together with any amendments or
supplements thereto, collectively constitute the "Offer"). The amendments to
Schedule TO-T set forth below are reflected in the Offer to Purchase dated April
11, 2002, attached to this Amendment as Exhibit (a)(10).

ITEM 2.  SUBJECT COMPANY INFORMATION.

         Item 2 of the Schedule TO-T, which incorporates by reference the
information contained in the Offer to Purchase, is hereby amended and
supplemented as follows:

         The section of the Offer to Purchase entitled "The Tender Offer -
         Section 6. Price Range of Shares; Dividends" is hereby amended and
         supplemented by adding the following at the end of the chart showing
         stock prices:

                 [INTERSTATE HOTELS CORPORATION (NASDAQ: IHCO)]



        [CALENDAR YEAR                            HIGH($)       LOW($)      DIVIDEND($)]
                                                                   
        2002
        First Quarter                             2.50          1.40        -0-
        Second Quarter (April 1 - April 10)       2.64          2.16        -0-


          On April 2, 2002, the day prior to the day the Purchaser first

     on Nasdaq at $2.16 per share. Since that date the shares of the Company
     have closed on Nasdaq in the range of $2.36 to $2.64 per share. On April
     10, 2002, the Company's shares closed at $2.60 per share. You should obtain
     a recent quotation for your shares before you decide whether or not to
     tender.



ITEM 5.  PAST CONTACTS, TRANSACTIONS, NEGOTIATIONS AND AGREEMENTS.

     Item 5 of the Schedule TO-T, which incorporates by reference the
information contained in the Offer to Purchase, is hereby amended and
supplemented as follows:

     The section of the Offer to Purchase entitled "The Tender Offer - Section
     11. Background of this Offer; Past Contacts, Transactions or Negotiations
     with the Company" is hereby amended and supplemented by adding the
     following at the end of that Section:

          On April 3, 2002, Mr. Hewitt sent a letter to Mr. Shaner responding to
     Mr. Shaner's letter to the Board of the Company sent on March 21, 2002. Mr.
     Hewitt asserted that the Company believed that its treatment of the
     $25,000,000 as cash on the balance sheet is entirely appropriate. Mr.
     Hewitt also addressed the Worldgate investment. He noted that the Worldgate
     investment was approved unanimously by the Company's Board several months
     prior to the investment by the Investor Group. Finally, Mr. Hewitt
     acknowledged receipt of the shareholder proposals provided by the Shaner
     Hotel Group on March 25 and March 28, 2002.

          On April 3, 2002, the Company issued a press release stating that
     Interstate had authorized a special committee of its independent directors
     to review and evaluate the terms and conditions of the Offer of Shaner
     Hotel Group, and that the special committee and the full Board would make a
     recommendation to shareholders no later than Tuesday, April 16, 2002, about
     the Offer.

          In a letter sent to Mr. Hewitt on April 10, 2002, Shaner Hotel Group
     reiterated its position that the failure of the Company to segregate the
     $25,000,000 of restricted cash on the face of the balance sheet is in
     direct contravention of SEC rules. In the letter, Mr. Shaner raised
     additional issues regarding the Worldgate investment. Mr. Shaner maintained
     that if the Worldgate investment was approved prior to the Investor Group
     financing, the investment should have been disclosed in the proxy
     solicitation materials sent to the shareholders of the Company seeking
     their approval of the financing with the Investor Group, and that no such
     disclosure was made in those materials.

          On April 11, 2002, Shaner Hotel Group filed with the Securities and
     Exchange Commission its Schedule TO-TA relating to this Offer and
     incorporating an updated Offer to Purchase, and published a summary
     advertisement in The New York Times announcing the Offer, its terms, and
     how to obtain more information about and copies of the Offer.



ITEMS 6 AND 1. PURPOSES OF THE TRANSACTION AND PLANS OR PROPOSALS, and SUMMARY
TERM SHEET.

     Item 6 of the Schedule TO-T, which incorporates by reference the
information contained in the Offer to Purchase, is hereby amended and
supplemented as follows.

     The section of the Offer to Purchase entitled "The Tender Offer - Section
     12. Purpose of this Offer; Plans for the Company" is hereby amended and
     supplemented by changing the second full paragraph in that section to read
     in full as follows:

          The Purchaser's current plans for the Company are to complete the
     Offer, subject to the satisfaction or waiver of important conditions, to
     nominate and to vote for two candidates for election to the Company's board
     of directors at this year's annual meeting of shareholders, and to exercise
     the rights of a Class A Common shareholder. The board of directors
     currently consists of eleven members, five of whom are elected by the
     holders of Class A Common Stock, one by the holder of Class B Common Stock,
     and five by the holders of Series A Preferred Stock. The terms of the Class
     A directors are staggered, with two director seats up for election in 2002,
     one in 2003, and two in 2004. The Purchaser intends to nominate and to vote
     for one director candidate at the annual shareholder meeting in 2003 and
     two director candidates in 2004. The Purchaser also intends to use its
     representation on the board of directors to try to exert influence and
     control over the management and affairs of the Company. In addition,
     following the completion of this Offer, and in accordance with all
     applicable requirements and restrictions of the Company's articles of
     incorporation and bylaws, and of applicable law, the Purchaser will
     consider seeking to accomplish some or all of the following objectives in
     cooperation with the appropriate persons or entities.

     Item 1 of the Schedule TO-T, which incorporates by reference the
information contained in the Offer to Purchase, is hereby amended and
supplemented by changing, in the Section of the Offer to Purchase entitled
"Summary Term Sheet," the lead-in paragraph under the caption "What are your
plans for the Company" to read in full as set forth above for the change to
Section 12 of the Offer to Purchase.
