         FOURTH AMENDMENT AND OVERRIDE AGREEMENT, dated as of September 6, 2000
(this "Override Agreement"), to the Credit Agreement, dated as of August 11,
1999 (as amended, supplemented or otherwise modified prior to the date hereof,
the "Existing Credit Agreement"; as modified hereby and as further amended,
supplemented or otherwise modified from time to time, the "Credit Agreement"),
among CELADON GROUP, INC., a Delaware corporation ("Group") and CELADON TRUCKING
SERVICES, INC., a New Jersey corporation ("Trucking"; together with Group, each
a "Borrower", collectively, the "Borrowers") the banks and other financial
institutions parties thereto (the "Lenders"), and ING (U.S.) CAPITAL LLC, as

                                    RECITALS

         The Borrowers have requested that the Administrative Agent and
the Lenders agree to amend and override certain provisions of the Credit
Agreement as set forth in this Override Agreement. The Administrative Agent and
the Lenders parties hereto are willing to agree to such amendments and
overrides, but only on the terms and subject to the conditions set forth herein.

         NOW, THEREFORE, in consideration of the premises and for other
good and valuable consideration, the receipt and sufficiency of which is hereby
acknowledged, the Borrowers, the Administrative Agent and the Lenders hereby
agree as follows:

         1. Defined Terms. Unless otherwise defined herein, terms defined in the
Credit Agreement are used herein as therein defined.

         2. Overriding Provisions. The override provisions of this
Section 2 shall remain effective for the period (the "Override Period") from the
Override Agreement Effective Date (as defined below) to but not including
October 31, 2000 (the "Override Termination Date"). From and after the Override
Termination Date, the override provisions of this Section 2 shall automatically
terminate and the terms of the Existing Credit Agreement shall control;
provided, however, that during the Override Period, the following provisions
shall control, notwithstanding any provision to the contrary contained in the
Existing Credit Agreement:

         (a) The first paragraph of the Recitals to the Existing Credit
Agreement is hereby amended by deleting the number "$35,000,000" from subclause
(b) thereof, and by substituting the number "$37,000,000" in lieu thereof; and

         (b) Schedule 1.1 to the Existing Credit Agreement is hereby amended by
deleting such Schedule in its entirety and substituting in lieu thereof a new
Schedule 1.1 attached to this Overriding Agreement.
