                  MASTER SEPARATION AND DISTRIBUTION AGREEMENT

        This Master Separation and Distribution Agreement (this "Agreement") is
made and entered into as of the 30th day of September, 2002 by and among Yellow
Corporation, a Delaware corporation ("Yellow"), and SCS Transportation, Inc., a
Delaware corporation and a wholly owned subsidiary of Yellow ("SCST").
Capitalized terms used herein and not otherwise defined shall have the meanings
assigned to them in Article VII hereof.

                                    RECITALS

        A.     WHEREAS, Yellow is the sole stockholder of SCST, and SCST is the
               sole stockholder of the operating subsidiaries Saia Motor Freight
               Line, Inc. ("Saia") and Jevic Transportation, Inc. ("Jevic");

        B.     WHEREAS, Yellow's Board of Directors has determined pursuant to
               an integrated plan to (i) separate SCST, which comprises Yellow's
               non-union, regional operations, from Yellow's other businesses
               and operations (the "Separation") and (ii) distribute to Yellow's
               stockholders on a tax-free basis all of the outstanding shares of
               SCST's common stock (the "Distribution");

        C.     WHEREAS, Yellow's Board of Directors has determined that it is in
               the best interests of its stockholders to consummate the
               Separation and the Distribution;

        D.     WHEREAS, it is appropriate and desirable to set forth the
               principal corporate transactions required to effect the
               Separation and the Distribution and certain other agreements that
               will govern certain matters relating to such transactions
               (collectively, the "Transactions") and the relationship of Yellow
               and SCST following the consummation of the Transactions;

NOW, THEREFORE, the parties, intending to be legally bound, agree as follows:

                              TERMS AND CONDITIONS

        In consideration of the mutual covenants herein, and other good and
valuable consideration, the receipt and adequacy of which are hereby
acknowledged, it is hereby agreed as follows:

               (i) Subject to Section 1.2 hereof, Yellow and SCST shall take all
reasonable steps necessary and appropriate to cause all conditions to the
Distribution to be satisfied and to effect the Distribution. Yellow's Board of
Directors will have the sole discretion to determine the Distribution Date, and
Yellow will consummate the Distribution subject to the satisfaction or waiver by
Yellow's Board of Directors, in its sole discretion, of the conditions set forth
in Section 1.2.

              (ii) On or prior to the Distribution Date, Yellow will deliver to
the Distribution Agent for the benefit of the holders of record of Yellow Common
Stock on the Record Date, stock certificates, endorsed by Yellow in blank,
representing all of the outstanding shares of SCST Common Stock, and shall cause
the transfer agent for the Yellow Common Stock to instruct the Distribution
Agent to distribute on the Distribution Date the appropriate number of such
shares of SCST Common Stock to each such holder or designated transferee or
transferees of such holder.

             (iii) Subject to Section 1.3 hereof, each holder of record of
Yellow Common Stock (or such holder's designated transferee or transferees) on
the Record Date will be entitled to receive in the Distribution that number of
shares of SCST Common Stock equal to that number of shares of Yellow Common
Stock owned by such holder on the Record Date divided by a number equal to the
Distribution Ratio established by Yellow's Board of Directors.

        1.2    Conditions to Distribution.

               1.2.1  The obligations of each party hereto to consummate the

                               any time prior to the Record Date;

                       (x)     Yellow's Board of Directors shall be satisfied
                               that the Distribution does not constitute the
                               conveyance of all or substantially all of the
                               properties or assets of Yellow immediately prior
                               to the Distribution, as contemplated in Section
                               271 of the Delaware General Corporation Law;

                       (xi)    the Certificate of Incorporation and By-laws
                               shall be in effect;

                       (xii)   no other events or developments shall have
                               occurred that, in the sole judgment of Yellow,
                               would result in the Distribution having a
                               material adverse effect on Yellow or its
                               stockholders;

                       (xiii)  Yellow's Board of Directors shall be satisfied
                               that each of Yellow and SCST will be solvent
                               following the Distribution; and

                       (xiv)   SCST shall have made the Yellow Payment.

        1.3 Sale of Fractional Shares. The Distribution Agent shall not
distribute any fractional shares of SCST Common Stock ("Fractional Shares") to
any record holder of Yellow Common Stock in connection with the Distribution.
The Distribution Agent shall be instructed to aggregate all such Fractional
Shares and sell them in an orderly manner promptly after the Distribution Date
in the open market at the then-prevailing prices and, after completion of all
such sales, distribute a pro rata portion of the gross proceeds from such sales,
less appropriate deductions of the amount required to be withheld for federal
income tax purposes, to each record holder of Yellow Common Stock who would
otherwise have received a Fractional Share. Yellow shall pay all brokerage
charges, commissions and transfer taxes attributed to such sale.

        1.4 Sole Discretion of Yellow. The conditions set forth in Section 1.2
are for the sole benefit of Yellow and shall not give rise to or create any duty
on the part of Yellow or Yellow's Board of Directors to waive or not to waive
such conditions or limit in any way Yellow's right to terminate this Agreement
or alter the consequences of any such termination. Any determination made by
Yellow prior to the Distribution concerning the satisfaction or waiver of any or
all of the conditions set forth in Section 1.2 shall be conclusive. In addition,


                                      -5-


Yellow shall have the sole and absolute discretion to determine the date of
consummation of the Distribution (such date, the "Distribution Date"), all terms
of the Distribution, including without limitation the form, structure and terms
of any transaction(s) and/or offering(s) to effect the Distribution or related
to the Distribution and the timing of and conditions to the consummation of the
Distribution. In addition, Yellow may in its sole and absolute discretion at any
time and from time to time until the Distribution Date, modify or change the
terms of the Distribution, including without limitation accelerating or delaying
the timing of the consummation of all or part of the Distribution. SCST shall
cooperate with Yellow in all respects to accomplish the Distribution and shall,
at Yellow's direction, promptly take any and all actions necessary and desirable
to effect the Distribution, including without limitation the registration under
the Exchange Act of the SCST Common Stock on an appropriate registration form.
Yellow shall in its sole and absolute discretion select any investment bank and
managers in connection with the Distribution, as well as any financial printer,
solicitation and/or exchange agent and its own outside counsel.

        1.5 Termination of Obligations. The obligations of Yellow and SCST under
this Agreement shall terminate on a determination by Yellow to terminate the
transactions that comprise the Distribution.

                                   ARTICLE II

                       DIVISION OF ASSETS AND LIABILITIES


        2.1 Transfer of Assets and Liabilities.

               (a) On the terms and subject to the conditions set forth in
this Agreement and with effect as of the Contribution Date, Yellow hereby
contributes, assigns, transfers, conveys and delivers to SCST, and shall cause
its applicable Subsidiaries to contribute, assign, transfer, convey and deliver
to SCST or a member of the SCST Group, all of Yellow's and such applicable
Subsidiaries' respective rights, title and interest in and to the assets set
forth in paragraph 2.1 of the Disclosure Letter (the "Contributed Assets").
SCST, or the appropriate member of the SCST Group, hereby accepts from Yellow
and its Subsidiaries the Contributed Assets.

               (b) On the terms and subject to the conditions set forth in this
Agreement and with effect as of the Contribution Date, SCST hereby accepts,
assumes and agrees faithfully to perform, discharge and fulfill all the
liabilities set forth in paragraph 2.1 of the Disclosure Letter (the
"Contributed Liabilities") in accordance with their respective terms, and agrees
to cause its applicable Subsidiaries to accept, assume, perform, discharge and
fulfill all the Contributed Liabilities to be held by its Subsidiaries in
accordance with their respective terms. SCST shall thereafter be responsible for
all Contributed Liabilities, regardless of


                                      -6-


(i) when or where such liabilities arose or arise, (ii) whether the facts on
which they are based occurred prior to or subsequent to the date hereof, (iii)
where or against whom such liabilities are asserted or determined (including
without limitation any liabilities arising out of claims made by Yellow's or
SCST's respective directors, officers, employees, agents, Subsidiaries or
Affiliates against any member of the Yellow Group or the SCST Group), (iv)
whether such liabilities were asserted or determined prior to the date hereof,
and (v) whether such liabilities arise from or are alleged to arise from
negligence, recklessness, violation of law, fraud or misrepresentation by any
member of the Yellow Group or the SCST Group or any of their respective
directors, officers, employees, agents, Subsidiaries or Affiliates.

               (c) In the event that at any time or from time to time (whether
prior to or after the Contribution Date), any party hereto (or any member of
such party's respective Group) shall receive or otherwise possess any asset that
is allocated to any other Person pursuant to this Agreement, such party shall
promptly transfer, or cause to be transferred, such asset to the Person so
entitled thereto. Prior to any such transfer, the party possessing such asset
shall hold such asset in trust for any such other party, and upon such transfer
each party shall reimburse the other or make financial or other adjustments to
remedy any liabilities resulting from such transfer or possession.

        2.2 Allocated Employees. As of the Distribution, the employees of Yellow
listed in paragraph 2.2 of the Disclosure Letter shall become employees of SCST

exchange for additional restricted shares of Yellow Common Stock commensurate in
value to the impact of the Distribution on the value of their previous

                      other person in accordance with the documentation
                      governing such Guarantee. With respect to any Guarantees
                      the cancellation of which requires the consent of a third
                      party, SCST shall, subject to the following sentence, use
                      its reasonable best efforts following the Distribution

                               between Yellow and SCST. To the extent that any
                               party pays any expenses that were determined by
                               Yellow to be properly allocable to the other
                               party, such other party shall reimburse the

                               Yellow of the total of all premiums paid since

                               coverage under the self-insurance retention pool
                               which has been maintained by Yellow to buy down
                               the self-insurance retentions of Jevic and Saia
                               (and Action Express, Inc. and WestEx, Inc.,
                               merged into Saia effective March 4, 2001) from
                               external retention levels of third-party
                               insurance providers. To this amount there shall
                               be added $1,014,783.00, representing SCST's and
                               its Subsidiaries' shares of the "bank" that has
                               been established with AI Transport, Inc. of

                               and SCST's Subsidiaries over the course of
                               Yellow's insurance arrangements with AIT. All
                               payments made by AIT to Yellow prior to or after
                               the Distribution Date shall be retained solely by
                               Yellow.

                               paragraph, there shall be subtracted a sum equal
                               to a calculation made by Yellow of the actual
                               claim payments made by Yellow to resolve claims
                               involving SCST and its Subsidiaries within the

                               "Net Ultimate Liability of Yellow" and the
                               calculation being detailed in paragraph 2.5.2.2
                               of the Disclosure Letter).

                               Yellow to fall within the self-insurance pool
                               that arise out of, in connection with or with
                               reference to activity of SCST and its
                               Subsidiaries prior to the Distribution Date
                               (together the "SCST Excess Liability") shall be
                               paid first by Yellow after the Distribution Date
                               up to the Net Ultimate Liability of Yellow. If
                               and when said Net Ultimate Liability of Yellow is
                               exhausted, all remaining liability for SCST
                               Excess Liability shall be paid by SCST and its
                               Subsidiaries, and SCST shall indemnify Yellow for
                               any claims asserted against Yellow for amounts of
                               SCST Excess Liability in excess of the Net

                               Section 4.4 if Yellow determines that Yellow or
                               any of its Subsidiaries has made any direct or
                               indirect payment in respect of SCST Excess
                               Liability in excess of the Net Ultimate Liability
                               of Yellow.

                                        amount of the Collateral for such fiscal
                                        quarter as determined by Yellow.

                                    (6) Collateral Cost for any fiscal quarter
                                        ending after the seventh anniversary of
                                        the Distribution Date shall equal the
                                        sum of (a) the Billed Cost for such
                                        fiscal quarter plus (b) 125 basis points
                                        multiplied by the average daily face
                                        amount of the Collateral for such fiscal
                                        quarter as determined by Yellow.

                               The Collateral Cost shall be billed on a
                               quarterly basis in arrears following the
                               Distribution Date. If Yellow receives a refund
                               from collateral providers for the Billed Cost of
                               Collateral that SCST has replaced following
                               Yellow's payment of the annual cost of such
                               Collateral, Yellow shall reimburse SCST the
                               amount of such Billed Cost and related premium
                               paid by SCST or any of its Subsidiaries to Yellow
                               or any of its Subsidiaries within 15 calendar
                               days of receipt by Yellow of such refund. Payment
                               of the Collateral Cost by SCST shall be due
                               within 15 calendar days after receipt by SCST of
                               the applicable Yellow bill or invoice.

                               After the Distribution, Yellow shall leave
                               existing Collateral in place until such
                               Collateral has been released by its holders,
                               except that SCST immediately after the
                               Distribution shall replace $15 million of the
                               existing Collateral detailed in paragraph 2.5.2.3
                               of the Disclosure Letter with Collateral obtained
                               by SCST. Notwithstanding the foregoing, in the
                               event that SCST experiences demands for increased
                               Collateral from any of the holders of such
                               Collateral detailed in paragraph 2.5.2.3 of the
                               Disclosure Letter between the Distribution Date
                               and February 28, 2003, Yellow shall either
                               provide such increased Collateral or instruct
                               SCST to provide such increased Collateral with a
                               credit against SCST's replacement Collateral
                               obligation described above, at Yellow's option.


                                      -12-


                               Yellow shall provide no additional Collateral to
                               SCST or any of SCST's Subsidiaries for any
                               insurance or self-insurance obligations arising
                               after February 28, 2003.

                               Notwithstanding the foregoing, in the event that
                               any holder of any Collateral provided by Yellow
                               redeems or calls such Collateral, SCST shall be
                               required to reimburse Yellow in accordance with
                               the procedures set forth in Section 4.4 and to
                               indemnify and hold Yellow harmless in accordance
                               with Section 4.3.

                      2.5.2.4  Claims Administration Obligations. Yellow and
                               SCST acknowledge that Yellow currently receives
                               invoices for claims administration expenses
                               provided by third-party administrators ("TPAs")
                               that pertain in whole or in part to the handling
                               and disposition of claims on behalf of Saia under
                               SCST's and Saia's insurance programs for years
                               prior to the year ended March 1, 2000. Yellow
                               shall continue to pay such invoices by TPAs after
                               the Distribution Date and SCST and Saia shall be
                               jointly or severally obligated to reimburse
                               Yellow for the portion of such invoices which
                               relate to services performed by TPAs on behalf of
                               Saia. Yellow shall not pay the portion of any
                               such invoices as relate to services performed on
                               behalf of Saia until SCST and/or Saia has
                               verified in writing the correctness of the
                               billing, which SCST or Saia must do within
                               fifteen (15) calendar days of presentment of the
                               invoice by Yellow to SCST. If SCST or Saia does
                               not deliver such written verification on or prior
                               to the date that is fifteen (15) calendar days
                               after the presentment of such invoice, Yellow
                               shall regard SCST as having verified such
                               invoice. Yellow will use its reasonable efforts
                               to contest any such billing on Saia's behalf, and
                               the parties will provide all reasonable
                               cooperation required to resolve any billing
                               disputes. If Yellow and SCST decide not to pay a
                               disputed invoice or to pay only a portion
                               thereof, SCST will indemnify Yellow from any
                               damages or costs incurred by Yellow stemming from
                               such non-payment or partial payment in accordance
                               with Section 4.3. SCST or Saia, as the case may
                               be, shall reimburse Yellow within fifteen (15)
                               calendar days of Yellow's payment of that portion
                               of each TPA invoice that relates to performance
                               by TPAs of services on their behalf.


                                      -13-

                      responsibility of Yellow, and Yellow shall be the sole
                      beneficiary of any payment of the claim in bankruptcy that
                      has been filed by Yellow against Preston, either for
                      amounts already claimed or to be claimed in the future,

                      Preston, that is presently held by Yellow. Following the
                      Distribution Date, Yellow shall indemnify and hold SCST
                      harmless in accordance with Section 4.3 for claims which
                      in any manner relate to or stem from the bankruptcy of

                      future prosecution of any claim against Luciano and/or
                      Luis Saia, III for these unpaid interline receivables
                      after the Distribution and SCST and/or Saia shall be the
                      recipients of any and all judgment, settlement or other
                      recovery ultimately achieved as a result of or in
                      connection with such litigation against Luciano and Luis
                      Saia, III, after the payment to Yellow of all expenses,
                      including without limitation attorneys' fees up to a
                      maximum of $25,000, that Yellow determines that it or any

                      connection with such litigation shall be paid first to
                      Yellow in full satisfaction of the Yellow Luciano

                      sight as the TPA of Saia's medical plan. SCST and Saia

                      recipients of any and all judgment, settlement or other
                      recovery ultimately achieved as a result of such
                      litigation against Benesight, after the payment to Yellow
                      of all expenses, including without limitation attorneys'
                      fees up to a maximum of $20,000, that Yellow determines
                      that it or any of its Subsidiaries (other than SCST or
                      Saia) has incurred in the prosecution of this claim prior
                      to the Distribution (together, the "Yellow Benesight

                      a result of or in connection with such litigation shall be
                      paid first to Yellow in full satisfaction of the Yellow
                      Benesight Litigation Expenses, promptly upon receipt
                      thereof by any member of the SCST Group, and then to SCST
                      or another member of the SCST Group.

               2.6.4  Remaining Action Express Purchase Obligations. Pursuant to
                      the Purchase Agreement entered into between Dan and David
                      Fulkerson and Yellow for the issued and outstanding shares

                      laws of the state of Delaware.

               (b)    Authority and Status. Yellow has full power and authority

                      executed and delivered, constitute the valid and legally
                      binding obligations of Yellow, enforceable against it in
                      accordance with their respective terms, except as
                      enforceability may be limited by applicable equitable
                      principles or by bankruptcy, insolvency, reorganization,
                      moratorium or similar laws from time to time affecting the
                      enforcement of creditors' rights generally.

               (c)    Litigation. To the knowledge of Yellow, there is no claim,
                      litigation, action, suit or proceeding, administrative or
                      judicial, pending or threatened against Yellow or related
                      to the business or the assets transferred pursuant to this
                      Agreement or the transactions contemplated hereunder, at
                      law or in equity, before any federal, state, local or
                      foreign court or regulatory agency, or other governmental
                      authority, which could result


                                      -16-


                      in the institution of legal proceedings to prohibit or
                      restrain the consummation or performance of this Agreement
                      or the transactions contemplated hereby, or claim damages
                      as a result of this Agreement or the transactions
                      contemplated hereby.

               (d)    No Conflict. Neither the execution and delivery of this
                      Agreement and the Tax Sharing Agreement nor compliance
                      with the terms and provisions hereof and thereof,
                      including, without limitation, the consummation of the
                      transactions contemplated hereby and thereby, will
                      conflict with or result in the breach of any term,
                      condition or provisions of Yellow's Certificate of
                      Incorporation or By-laws or applicable law, regulation or
                      court order.

        3.2 Representations and Warranties of SCST. SCST represents and warrants
to Yellow as follows:

               (a) Organization and Standing. SCST is a corporation duly
        organized, validly existing and in good standing under the laws of the
        state of Delaware.

               (b) Authority and Status. SCST has full power and authority to
        execute and deliver this Agreement and the Tax Sharing Agreement, to
        perform its obligations hereunder and thereunder and consummate the
        transactions contemplated hereby and thereby without the necessity of
        any act or consent of any other person. SCST has taken all necessary and
        appropriate corporate action, including obtaining all necessary board
        and shareholder consents with respect to the execution, delivery and
        performance by SCST of this Agreement and of the Tax Sharing Agreement.
        This Agreement and the Tax Sharing Agreement constitute or will when
        executed and delivered constitute the valid and legally binding
        obligation of SCST enforceable against it in accordance with their
        respective terms, except as enforceability may be limited by applicable
        equitable principles or by bankruptcy, insolvency, reorganization,
        moratorium or similar laws from time to time affecting the enforcement
        of creditors' rights generally.

               (c) No Conflict. Neither the execution and delivery of this
        Agreement and the Tax Sharing Agreement nor the terms and provisions
        hereof and thereof including, without limitation, the consummation of
        the transactions contemplated hereby and thereby will conflict with or
        result in the breach of any term, condition or provisions of the
        Certificate of Incorporation or By-laws, as amended and restated, or
        applicable law, regulation or court order.



                                      -17-


                                   ARTICLE IV

                                 RELATED MATTERS


        4.1 Access to Information.

               (a) From and after the Distribution Date, each of Yellow and
SCST, on behalf of its respective Group, agrees to provide or cause to be
provided to the other Group any Information in the possession or under the
control of such Group which the requesting party reasonably needs

               (i) to comply with reporting, disclosure, filing or other
        requirements imposed on the requesting party (including under applicable
        securities laws) by a Governmental Authority having jurisdiction over
        the requesting party;

               (ii) for use in any other judicial, regulatory, administrative or
        other proceeding or in order to satisfy audit, accounting, claims,
        regulatory, litigation or other similar requirements, in each case other
        than claims or allegations that one party to this Agreement has against
        the other; or

               (iii) subject to the foregoing clause (ii), to comply with its
        obligations under this Agreement or the Tax Sharing Agreement;

provided, however, that in the event that any party hereto determines that any
such provision of Information could be commercially detrimental, violate any law
or agreement, or waive any attorney-client privilege, the parties shall take all
reasonable measures to permit the compliance with such obligations in a manner
that avoids any such harm or consequence.

               (b) Except as otherwise specifically provided for herein, a
party providing Information or witnesses to the other hereunder shall be
entitled to receive from the recipient, upon the presentation of appropriate
invoices therefor, payments for such amounts relating to supplies, out-of-pocket
expenses, and such other costs, employee time and disbursements, which may be
reasonably incurred in providing such Information or witnesses. Invoices shall
be due and payable within fifteen (15) calendar days of receipt. Employee time
shall be billed at the involved employee's hourly rate for hourly employees with
a four-hour minimum, and salary calculated on a per diem basis for salaried
employees with a one calendar day minimum.

        4.2 Confidentiality. Each of Yellow and its Subsidiaries (other than
SCST and its Subsidiaries) and SCST and its Subsidiaries shall hold and cause
each of their respective officers, directors, employees, agents, consultants and
advisors to hold, in strict confidence, all non-public information concerning
the other party, unless compelled to disclose such informa-


                                      -18-


tion by judicial or administrative process or, in the opinion of counsel, by the
requirements of law (in which case such party shall promptly notify the other
party so that the other party may seek a protective order or other appropriate
remedy). Each party shall not release or disclose such information to any other
person except its auditors, attorneys, financial advisors, bankers,
subcontractors and other consultants and advisors who have a need to know, who
shall be bound by the provisions of this Section 4.2. Each party shall be deemed
to have satisfied its obligations hereunder with respect to confidential
information supplied by the other party if it exercises the same care as it does
to preserving the confidentiality of its own similar information.

        4.3 Indemnification.

               (a) Except as otherwise provided in this Agreement, Yellow
shall indemnify SCST, its Subsidiaries and their officers, directors, managers,
members, employees, agents, affiliates and advisors (collectively, the "SCST
Indemnitees") from and against and shall reimburse such SCST Indemnitees in
respect of any and all Losses resulting from or arising out of (i) any Yellow
Liabilities (whether arising prior to or after the Distribution Date), (ii) the
failure of Yellow to perform any of its obligations under this Agreement in any
material respect, and (iii) all Liabilities arising out of the business,
operations and assets of Yellow and Yellow's Subsidiaries after the Distribution
Date.

               (b) Except as otherwise provided in this Agreement, SCST shall
indemnify Yellow, its Subsidiaries and their officers, directors, managers,
members, employees, agents, affiliates and advisors (collectively, the "Yellow
Indemnitees") from and against and shall reimburse such Yellow Indemnitees in
respect of any and all Losses resulting from or arising out of (i) any of the
SCST Liabilities (whether arising prior to or after the Distribution Date), (ii)
the failure of SCST to perform any of its obligations under this Agreement in
any material respect, and (iii) all Liabilities arising out of the business,
operations and assets of SCST and SCST's Subsidiaries after the Distribution
Date.

               (c) Any Liabilities not allocated to Yellow or its
Subsidiaries or to SCST or its Subsidiaries hereunder shall be allocated to
either Yellow or SCST by the Chief Executive Officer of Yellow in his sole
discretion.

               (d) Neither party shall be liable for indemnification with
respect to any claim for which indemnification may result hereunder unless the
party seeking indemnification (the "Indemnitee") notifies the other party (the
"Indemnifying Party") in writing of the nature of the claim in as much detail as
is feasible within a reasonable time after the facts giving rise to such claim
are known to the Indemnitee. The Indemnifying Party shall be entitled to
participate at its own expense in the defense or, if it so elects by a writing
delivered to the Indemnitee within thirty (30) calendar days after receipt of
such notice, to assume at its own expense the defense of the matter giving rise
to the claim for indemnification or of any suit


                                      -19-


brought in connection with it. If the Indemnifying Party elects to assume a
defense and is reasonably creditworthy or carries insurance so as to make it
reasonable to expect it will be able to discharge an adverse judgment, the
defense shall be conducted by counsel chosen by it. Only one counsel will be
provided for the Indemnitee in any one proceeding regardless of the number of
entities or individuals to be indemnified and the Indemnifying Party shall be
able to settle if it obtains an unconditional release without limitations on
future conduct. If the Indemnitee elects to assume the defense of any such claim
or suit and retains such counsel, the Indemnitee shall bear the fees and
expenses of its own counsel arising out of any legal service thereafter
performed by that counsel. In the event the Indemnitee elects to defend against
any such claim it will, so long as the Indemnifying Party is actively engaged in
defense of the claim, refrain from paying or compromising the claim and will
extend its cooperation and assistance to the Indemnifying Party in its defense
against the claim. If the parties hereto or an Indemnitee is unable to agree
upon or settle any claim for indemnity, either party or an Indemnitee may submit
the Indemnitee claim to the dispute resolution procedure provided for herein.
Notwithstanding the foregoing, there shall be no obligation for one party to
indemnify the other for any dispute in which the amount in controversy is less
than $5,000.

        4.4 Manner of Payments. Except as otherwise provided in this Agreement,
any reimbursements or other payments to be made on and after the Distribution
Date by any party to any other party hereunder shall be due within fifteen (15)
calendar days of the receipt by the owing party of an invoice or other billing
documentation accompanied by reasonably detailed supporting information.

        4.5 Taxes. Yellow and SCST have entered into a Tax Sharing Agreement
regarding their respective rights and obligations with respect to taxes of
Yellow and SCST for all periods prior to (or including) the Distribution and
certain other tax related matters. In the event of any conflict between the
terms of the Tax Sharing Agreement and the terms of this Agreement, the terms of
the Tax Sharing Agreement shall prevail.

        4.6 Expenses. Except as otherwise provided in this Agreement or the Tax
Sharing Agreement, all out-of-pocket expenses incurred in connection with the
Distribution up to and including the Distribution Date shall be paid by Yellow.
Thereafter, except as otherwise provided in this Agreement or in the Tax Sharing
Agreement, each party shall bear its own expenses in connection with the
Distribution.

        4.7 Non-solicitation. For twenty-four (24) months after the date hereof,
Yellow and SCST shall not, directly or indirectly, offer, induce, recruit,
solicit, influence or attempt to influence any employee of the other or any of
its subsidiaries to terminate his or her employment for the purpose of working
for the other (without the prior written consent of the other party). This
Section 4.7 shall not prohibit one party from hiring an employee of the other
party if such employment is the result of an employee's soliciting employment by
the employ-


                                      -20-


ing party without any inducement or attempt by the employing party to encourage
said employee, or if the employment occurs as a result of a general solicitation
for employment by one party not specifically directed at the other party.

                                    ARTICLE V

                               DISPUTE RESOLUTION


        5.1 Use of Dispute Resolution; Presumptions. Except as otherwise set
forth in the Tax Sharing Agreement, resolution of any and all disputes arising
from or in connection with this Agreement or the Tax Sharing Agreement, whether
based on contract, tort or otherwise (collectively, "Disputes"), shall be
exclusively governed by and settled in accordance with the provisions of this
Article V, it being understood and agreed by SCST that any calculation or
determination made by Yellow with respect to or in connection with the
Distribution or this Agreement shall be deemed reasonable and binding on SCST
absent manifest error.

        5.2 Negotiation. The parties shall make a good faith attempt to resolve
any Dispute through negotiation. Within fifteen (15) calendar days after notice
of a Dispute is given by either party to the other party, each party shall
select a negotiating team comprised of vice president-level employees of such
party and shall meet within fifteen (15) calendar days after the end of the
first fifteen (15) calendar day negotiating period to attempt to resolve the
matter. During the course of negotiations under this Section 5.2, all reasonable
requests made by one party to the other for Information, including requests for
copies of relevant documents, will be honored. The specific format for such
negotiations will be left to the discretion of the designated negotiating teams
and may include the preparation of agreed upon statements of fact or written
statements of position furnished to the other party.

        5.3 Non-binding Mediation. In the event that any Dispute arising out of
or related to this Agreement is not settled by the parties within fifteen (15)
calendar days after the first meeting of the vice president-level negotiating
teams under Section 5.2, the parties will attempt in good faith to resolve such
Dispute by non-binding mediation in accordance with the American Arbitration
Association Commercial Mediation Rules as in effect at such time. Mediation
shall be held within thirty (30) calendar days of the end of such fifteen (15)
calendar day negotiation period of the negotiating teams. Except as provided in
Section 5.4, no litigation for the resolution of such Dispute may be commenced
until the parties attempt in good faith to settle the dispute by such mediation
in accordance with such rules and either party has concluded in good faith that
amicable resolution through continued mediation of the matter does not appear
likely. The costs of mediation shall be shared equally by the parties to the
mediation. Any settlement reached by mediation shall be recorded in writing,
signed by the parties, and shall be binding on them.



                                      -21-


        5.4 Proceedings. Nothing herein, however, shall prohibit either party
from initiating litigation or other judicial or administrative proceedings if
there is a substantial likelihood that such party would be substantially harmed
by a failure to act during the time that such good faith efforts are being made
to resolve the Dispute through negotiation or mediation. In the event that
litigation is commenced under this Section 5.4, the parties agree to continue to
attempt to resolve any Dispute according to the terms of Section 5.2 and Section
5.3 during the course of such litigation proceedings under this Section 5.4.

        5.5 Continuity of Service and Performance. Unless otherwise agreed in
writing, the parties will continue to provide service on all of the commitments
in this Agreement and the Tax Sharing Agreement during the course of dispute
resolution pursuant to the provisions of this Article V with respect to all
matters not subject to the Dispute.

        5.6 Further Assurances. In addition to the actions specifically provided
for elsewhere in this Agreement, each of the parties hereto shall use its
reasonable best efforts to (i) execute and deliver such further documents and
take such other actions as any other party may reasonably request in order to
effectuate the purposes of this Agreement and to carry out the terms hereof, and
(ii) take, or cause to be taken, all actions, and to do or cause to be done all
things reasonably necessary, proper or advisable under applicable law,
regulation and agreements or otherwise to consummate and make effective the
transactions contemplated by this Agreement, including without limitation using
its reasonable best efforts to obtain any consents and approvals and make any
filings and applications necessary or desirable in order to consummate the
transactions contemplated by this Agreement.

                                   ARTICLE VI

matter thereto and may not be changed in any way, except as provided in Section
6.3.

        6.3 Waiver and Modification. An amendment or modification of this
Agreement will be valid and effective only if it is in writing and signed by
each party to this Agreement. In addition, a waiver of any duty, obligation or
responsibility of a party under this Agreement will be valid and effective only
if it is evidenced by writing, signed by or on behalf of the party against whom
the waiver or discharge is sought to be enforced. The waiver by either party of


                                      -22-


a breach of a provision of this Agreement will not constitute a waiver of the
succeeding breach of the provision or a waiver of the provision itself.
