                               AMENDMENT NO. 1 TO
                               OPERATING AGREEMENT

         THIS AMENDMENT NO. 1 TO OPERATING AGREEMENT ("Amendment") is executed
as of November 9, 2000 by and among TA Operating Corporation, a Delaware
corporation ("TA Operating"), TA Franchise Systems, Inc., a Delaware corporation
("TA Franchise") and Freightliner LLC, a Delaware limited liability company that
was formerly a Delaware corporation known as Freightliner Corporation
("Freightliner").

                                   WITNESSETH:

     WHEREAS, TA Operating, TA Franchise and Freightliner are parties to that
certain Freightliner Express Operating Agreement dated July 21, 1999 (the
"Operating Agreement"); and

     WHEREAS, TA Operating, TA Franchise and Freightliner have agreed to amend
the Operating Agreement, in accordance with Section 8.5 thereof, pursuant to the
terms set forth herein;

         NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, the parties hereto agree as
follows:

     1. Section 6.1 of the Operating Agreement shall be deleted in its entirety
and replaced as follows:

                  "6.1 TERM. This Agreement shall have an initial term of ten
years and thereafter shall be terminable upon six months' advance notice given
by either party to the other. This Agreement shall also be terminable by either
party in accordance with Section 6.2 or by Freightliner in accordance with
Section 8.4. Except as otherwise provided in Section 6.2 or Section 8.4, any
notice of termination may be given no earlier than the date six months prior to
the expiration date of the initial term and the effective date of termination
shall be the date six months after the date of the giving of such notice. Until
an effective notice of termination is given by either party and the effective
date of the termination is reached, this Agreement shall continue in full force
and effect."

     2. Section 8.4 of the Operating Agreement shall be deleted in its entirety
and replaced as follows:

                  "8.4     ASSIGNMENT; FREIGHTLINER'S RIGHT TO TERMINATE IN
CONNECTION WITH CHANGE OF CONTROL WITH OFFEROR. This Agreement and the rights
and obligations hereunder may not be assigned, delegated, sold, transferred or
encumbered in whole or in part by Freightliner or TA Operations without the
prior written approval of the other party. The foregoing prohibition on
assignment without prior written approval shall not apply, however, to any
direct or indirect assignment of this Agreement (including by merger) that would
occur in connection with any transaction involving any of TravelCenters, TA
Operations or any successor to TravelCenters or TA Operations that would result
in a Change of Control as defined in that certain Stockholders' Agreement
relating to TravelCenters of America, Inc. attached as Exhibit A to that certain
Freightliner Equity Rollover Agreement dated November 9, 2000 between
Freightliner and TCA Acquisition Corporation, a Delaware corporation ("2000
Stockholders' Agreement"). Notwithstanding the foregoing, however, Freightliner
shall have the right to elect to terminate this Agreement in the case of any
proposed Change of Control transaction with an Offeror (as defined in the 2000
Stockholders' Agreement) regardless of whether the 2000 Stockholders' Agreement
is then in effect; provided that if the 2000 Stockholders' Agreement is then in
effect and the Change of Control therefore would trigger the right of first
purchase provided for under Section 3.7 of the 2000 Stockholders' Agreement,
Freightliner shall have first been given the opportunity in accordance with said
Section 3.7 to exercise its right of first purchase and there shall have been no
effective exercise by Freightliner of such right of first purchase. Any election
by Freightliner to terminate this Agreement in accordance with this Section 8.4
shall be made by a notice of termination delivered to TA Operations prior to the
expiration of Freightliner's right of first purchase under Section 3.7 of the
2000 Stockholders' Agreement (if the 2000 Stockholders' Agreement is then in
effect) or within 30 days after notice from TA Operations of the proposed Change
in Control transaction (if the 2000 Stockholders' Agreement is not in effect).
Any such termination shall be effective only in the event a Change of Control
transaction with an Offeror is consummated, in which case the termination shall
be effective as of the date of the Change of Control.

         3.       Except as set forth in this Amendment, all other terms and
conditions of the Operating Agreement shall remain in full force and effect.

         IN WITNESS WHEREOF, the parties hereto, intending to be legally bound,
have executed this Amendment as of the date first above written.
