Gentlemen:

            Yellow Corporation, a Delaware corporation (the "Company"), hereby
agrees with you as follows:

            SECTION 1. Appointment of Paying Agent.

            The Company proposes to issue and sell up to $ in aggregate
principal amount of notes due from nine months to thirty years from date of
issue (the "Notes"), and has appointed Merrill Lynch & Co., Merrill Lynch,
Pierce, Fenner & Smith Incorporated (the "Placement Agent") as the Placement
Agent for such Notes. The Company hereby appoints Citibank, N.A. (the "Paying
Agent"), to act, on the terms and conditions specified herein, as issuing and
paying agent and registrar for the Notes.

            SECTION 2. Note Form; Signature.

            The Company will from time to time furnish the Paying Agent with an
adequate supply of registered Notes, without coupons, serially numbered, and
which will have the principal amount, date of issue, maturity date and rate of
interest left blank. Each will be signed (either manually or by mechanical
impression (facsimile signature) in the name and on behalf of the Company by any
two of the President, and any Vice President and the Treasurer of the Company,
or any one of the foregoing and any Assistant Treasurer of the Company acting
jointly (the "Requisite Officers"). The Notes will be substantially in the form
of Exhibit A hereto and shall have a maturity of not less



                                       -2-

incumbency and specimen signatures of Requisite Officers. Until the Paying
Agent receives a subsequent incumbency certificate, the Paying Agent shall be
entitled to rely on the information set forth in the incumbency certificate it
last received for purposes of determining the Requisite Officers. The Paying
Agent shall not have any responsibility to determine whether any signature on a
Note purporting to be that of a Requisite Officer is genuine, so long as such
signature resembles the specimen signature set forth in the original incumbency
certificate or in a subsequent certificate delivered to the Paying Agent. Any
Note bearing the signatures of two persons each of whom is a Requisite Officer
on the date he signs such Note shall be a binding obligation of the Company upon
the completion and countersignature thereof by the Paying Agent, notwithstanding
that such person shall have died or shall have ceased to hold his office or
shall have ceased to be a Requisite Officer on the date such Note is completed,
countersigned or delivered by the Paying Agent except as the Company has
notified the Paying Agent otherwise by delivery of a new incumbency certificate.

agreements between the Company and the Paying Agent. Oral instructions will

in immediately available funds sufficient to pay the principal of any such Note,
together with accrued interest due at maturity.

            SECTION 10. Registration; Transfer.

            (a) The Paying Agent shall maintain a register in which it shall
register the names, addresses and taxpayer identification numbers of the holders
of the Notes in accordance with information provided pursuant to Section 4
thereof and shall register the transfer of the Notes to the extent permitted by

                                      -6-


of such Note for the purposes of receiving, payment of the principal of and
interest on such Note and for all other purposes whatsoever, whether or not such
Note be overdue, and neither the Company nor the Paying Agent shall be affected
by notice to the contrary.

            (c) The Paying Agent shall not register the attempted transfer of
any Note unless it has received the written consent and confirmation of the
Company and the applicable Placement Agent to such transfer stating that such
transfer is subject to the transfer restrictions as set forth in the Note
(attached hereto as Exhibit A) and that such transfer is being made pursuant to
Rule 144A ("Rule l44A") of the Securities Act of 1933, as amended (the "1933
Act") to (i) a "qualified institutional buyer" (as defined in Rule l44A) under
Rule 144A or Regulation S of the 1933 Act or (ii) to an "accredited investor"
(as defined in Rule 501(a) of the 1933 Act). The Paying Agent shall register
such transfer in accordance with the conditions of such consent.

            (d) All Notes presented for presented registration of transfer shall
be duly endorsed or be accompanied by a written instrument of transfer and a
certification that such transfer is pursuant to Rule 144A in a form reasonably
satisfactory to the Company, duly executed by the Registered Holder or his duly
authorized (in writing) attorney.

            SECTION 11. Mutilated, Lost, Stolen or Destroyed Notes.

            In case any Note shall become mutilated or destroyed, lost or

Paying Agent shall authenticate and deliver, a new Note having a number not
contemporaneously outstanding, in exchange and substitution for the affiliated
Note or in lieu of and substitution for the Note destroyed, lost or stolen. In
every such case, the applicant for a substituted Note shall furnish to the
Company and to the Paying Agent such security or indemnity as may be required by
them to save each of them harmless, and, in every case of destruction, loss or
theft, the applicant shall also furnish to the Company and to the Paying Agent
evidence to their satisfaction of the destruction, loss or theft of such Note
and of the ownership thereof. The Paying Agent may authenticate any such
substituted Note and deliver the same upon the written request or authorization
of the Requisite Officers. Upon the issuance of any substituted



                                      -7-


Note, the Company may require from the applicant the payment of a sum sufficient
to cover any expense connected therewith. In case any Note which has matured or
is about to mature shall become mutilated or be destroyed, lost or stolen, the
Company may, instead of issuing a substitute Note, pay or authorize the payment
of the same (without surrender thereof except in the case of a mutilated Note)
if the applicant for such payment shall furnish the Company and the Paying Agent
with such security or indemnity as may be required by them to save each of them
harmless, and, in the case of destruction, loss or theft, evidence to the
satisfaction of the Company of the destruction, loss or theft of such Note and
of the ownership thereof. All applications under this Section 11 shall be
processed by the Paying Agent.

            SECTION 12. Satisfaction and Discharge.

            The Company at any time may satisfy all of its obligations with
respect to the Notes by irrevocably depositing in trust with the Paying Agent
cash or U.S. Government Securities with maturity dates, interest rates or yields
and principal amounts sufficient to pay the principal of and interest on all
such Notes as and when the same become due and payable. In the event of any such
deposit, the Paying Agent agrees that it will hold such cash or U.S. Government
Securities so deposited, in trust for the benefit of the holders of Notes, as
trust funds for payment of the principal of and interest on the Notes to which
such deposit relates. For the purposes hereof, the term "U.S. Government
Securities" means direct obligations of the United States of America to pay
principal which obligations are not callable at the issuer's option, or direct
obligations of the United States of America to pay interest, in each case for
the payment of which the full faith and credit of the United States of America
is pledged.

            SECTION 13. Return of the Unclaimed Funds.

            Any cash or U.S. Government Securities deposited with the Paying
Agent and remaining unclaimed for two years after the date upon which the last
payment of principal of or interest on any Note to which such deposit relates
shall have become due and payable, shall be repaid to the Company by the Paying
Agent on demand, and the holder of any Note to which such deposit related
entitled to receive payment shall thereafter look only to the Company for the
payment thereof and all liability of the Paying Agent with respect to such cash
or U.S. Government Securities shall thereupon cease.



                                      -8-


            SECTION 14. Resignation or Removal of Paying Agent.

            The Paying Agent may at any time resign as such Agent by giving
written notice to the Company of such intention on its part, specifying the date
on which its desired resignation shall become effective; provided, however, that
such date shall not be less than three months after receipt of such notice by
the Company. The Paying Agent may be removed at any time by the filing with it
of an instrument in writing signed on behalf of the Company and specifying such
removal and the date when it is intended to become effective. Such resignation
or removal shall take effect upon the date of the appointment by the Company of
a successor Paying Agent, and the acceptance of such appointment by such
successor Paying Agent.

            SECTION 15. Reliance on Instructions.

            The Paying Agent shall incur no liability in acting hereunder upon
instructions pursuant to Section 4 hereof and as otherwise contemplated hereby
which the Paying Agent believed in good faith and without gross negligence to
have been properly given.

            SECTION 16. Cancellation; Destruction of Cancelled and Unissued
Notes.

            All Notes surrendered for payment, registration of transfer or
exchange shall upon receipt be promptly cancelled by the Paying Agent. All
cancelled Notes shall be destroyed by the Paying Agent and the Paying Agent
shall forthwith deliver a certificate of such destruction to the Company. Upon
the written request of the Company, the Paying Agent shall promptly destroy all
unissued Notes in its possession and forthwith deliver a certificate of such
destruction to the Company.

            SECTION 17. Representation and Warranties of the Company.

            Each instruction given to the Paying Agent in accordance with
Section 4 hereof shall constitute a representation and warranty to the Paying
Agent by the Company that the issuance and delivery of the Notes have been duly
and validly authorized by the Company and when completed, countersigned and
delivered pursuant hereto, the Notes will constitute the valid and legally
binding obligations of the Company.



                                      -9-
