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

         (i)    Subject to Section 1.2 hereof, Yellow and SCST shall take all
reasonable steps necessary and appropriate to cause all conditions to the

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

                         the proceeds of such Debt Agreements, in the
                         approximate amount of $110.7 million, subject to
                         adjustment on a post-closing basis in the manner set
                         forth in paragraph 1.2.1(i)(c) of the Disclosure Letter
                         (the "Yellow Payment");

               (ii)  the Registration Statement shall have been filed and
                     declared effective by the Commission, and there shall be
                     no stop order in effect with respect thereto, and no
                     proceeding for that purpose shall have been instituted
                     or threatened by the Commission;

               (iii) the actions and filings with regard to state securities and
                     blue sky laws of the United States (and any comparable laws

                     Market, on official notice of distribution;

               (v)   no order, injunction or decree issued by any Government
                     Authority or other legal restraint or prohibition
                     preventing the consummation of the Distribution or any of
                     the other transactions contemplated by this Agreement or

                                      -4-



               (viii) Yellow's Board of Directors shall be satisfied that the
                      Distribution will be made out of surplus within the
                      meaning of Section 170 of the Delaware General
                      Corporation Law;

               (ix)   Yellow's Board of Directors shall have approved the
                      Separation and the Distribution and shall not have
                      abandoned or deferred the Distribution at 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,



<PAGE>



                                      -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



<PAGE>


                                      -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
(the "Allocated Employees"). Yellow shall not be responsible for insurance,
employee benefits and other related benefits of the Allocated Employees that
accrue from and after the Distribution Date except as may be provided in an
individual agreement between Yellow and any Allocated Employee. SCST shall be
responsible for all costs associated with the Allocated Employees from and after
the Distribution Date. Yellow shall not be responsible for any Cobra benefit, or
unemployment or workers' compensation benefit of an employee whose employment
ends or whose injury or death occurs while an employee of SCST. SCST shall
reimburse Yellow in accordance with the procedures set forth in Section 4.4 if
Yellow determines that it has made any direct or indirect payment in respect
thereof, including without limitation as a result of adjustment to its insurance
rates or government fund payment obligations. SCST's health and life insurance
plans will not exclude pre-existing conditions for the Allocated Employees
(except to the extent such pre-existing conditions were excluded from the
corresponding Yellow plan immediately prior to the Distribution Date), will
waive any waiting period requirements for the Allocated Employees, and will
waive any evidence of insurability provisions for the Allocated Employees. In
addition, SCST's health plans will apply toward any deductible requirements and
out-of-pocket maximum limits for the plan year in which the Distribution takes
place any amounts paid by an Allocated Employee toward such requirements and
limits under the Yellow health plan in which he or she participated during such
plan year. SCST shall, and shall cause its Subsidiaries to, grant the Allocated
Employees credit for their service

                                      -7-


with Yellow and its Subsidiaries prior to the Distribution Date for purposes of
eligibility to participate in and vesting in the benefit plans sponsored by SCST
and its Subsidiaries.

     2.3 Stock Options and Restricted Stock. The outstanding stock options held
by Yellow's directors, employees and other parties, including Allocated
Employees, to purchase stock of Yellow shall be adjusted in the manner set forth
in paragraph 2.3 of the Disclosure Letter. Certain senior officers of Yellow and
its Subsidiaries Yellow Transportation, Meridian IQ and Yellow Technologies have
received restricted stock grants. All such senior officers who are actively
employed by Yellow or any such Subsidiary on the Distribution Date will agree to
waive the shares of SCST Common Stock that they would otherwise have received in
exchange for additional restricted shares of Yellow Common Stock commensurate in
value to the impact of the Distribution on the value of their previous
restricted stock grants. The additional grants of restricted stock will be
subject to the same restrictions and vesting dates as the original grants.

     2.4 Third Party Debt. SCST and/or its subsidiaries shall make all future
interest and principal payments on and after the Distribution Date on all Third
Party Debt in addition to the Debt Agreements listed in paragraph 1.2.1 of the
Disclosure Letter which resides on the books of SCST or its subsidiaries as of
the Distribution Date, and SCST shall indemnify and hold Yellow harmless for
payment of interest or principal after the Distribution Date in accordance with
Section 4.3. Third Party Debt is listed in paragraph 2.4 of the Disclosure
Letter.

     2.5 Certain Financial Support Arrangements.

         2.5.1 Guarantees by Yellow of SCST Obligations. As of the date hereof,
               Yellow has provided guarantees of certain obligations of SCST and
               its subsidiaries, the holders, amount and duration of which are
               set forth in paragraph 2.5.1 of the Disclosure Letter (the
               "Guarantees"). As of the Distribution Date, Yellow shall cancel
               all Guarantees which it is permitted to cancel without the
               consent of any 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 Date to remove such Guarantee
               by Yellow of obligations of SCST and its Subsidiaries, and SCST
               shall indemnify and hold Yellow harmless from any damages,
               claims, monies or other demands incurred by or asserted against
               Yellow which arise out of, in connection with or with reference
               to any Guarantee in accordance with Section 4.3. SCST shall not

               Yellow will not extend any Guarantee beyond the end of the term
               of each obligation as in effect on the date hereof.

         2.5.2 Insurance, Collateral and Claims Administration Obligations.

               2.5.2.1 Insurance. Responsibility as between SCST and Yellow for
                       any self-insurance, retention, deductible, retrospective
                       premium, or similar items, including without limitation
                       associated administrative expenses and allocated loss
                       adjustment or similar expenses, arising after the
                       Distribution Date under any and all former or current
                       insurance policies maintained by Yellow and related to
                       liabilities or losses of SCST or its Subsidiaries prior
                       to the Distribution Date shall be allocated by Yellow to
                       SCST or Yellow (each of the foregoing being a "party")
                       on a basis not inconsistent with past practices 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 paying party in accordance with the
                       procedures set forth in Section 4.4.

               2.5.2.2 Self-Insurance Pool and AIT "Bank". As of the
                       Distribution Date, a calculation shall be made by
                       Yellow of the total of all premiums paid since inception
                       by SCST and its Subsidiaries for 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 Atlanta, Georgia ("AIT") relating
                       to certain third-party liability claims incurred by
                       Yellow an 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.

                       From the total derived in the preceding 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 self-insurance

                       retention pool from its inception to the Distribution
                       Date (the sum derived from this calculation hereinafter
                       being referred to as the "Net Ultimate Liability of
                       Yellow" and the calculation being detailed in paragraph
                       2.5.2.2 of the Disclosure Letter).

                       After the Distribution Date, claims determined by 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
                       Ultimate Liability of Yellow in accordance with Section
                       4.3. SCST shall reimburse Yellow in accordance with the
                       procedures set forth in 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.

               2.5.2.3 Collateral. In order to cover certain Collateral
                       Requirements (as defined below) of SCST and its
                       Subsidiaries, Yellow has provided letters of credit,
                       indemnity bonds or other collateral to secure certain
                       obligations of SCST and its subsidiaries for
                       self-insurance retention deductibles, retrospective
                       premiums and cash payment for reserves as set forth in
                       paragraph 2.5.2.3 of the Disclosure Letter. With respect

                     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

                     instruct SCST to provide such increased Collateral with a
                     credit against SCST's replacement Collateral obligation
                     described above, at Yellow's option.

                     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.

obligations of Yellow and potential claims against third parties exist which
shall be divided between Yellow and SCST as follows:

                     the bankruptcy of Preston, whether already incurred or to
                     be incurred in the future, shall be the sole 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, specifically including any
                     payment or valuation of the Warrant dated July 15, 1998, to
                     purchase shares of Preston, that is presently held by

                     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 Preston and the former ownership of
                     Preston by Yellow.

                     unpaid interline receivables that are owed by Luciano to

                     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

                     limitation attorneys' fees up to a maximum of $25,000, 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
                     Luciano Litigation Expenses"). Amounts received by SCST or

                     shall be paid first to Yellow in full satisfaction of the
                     Yellow Luciano Litigation Expenses, promptly upon receipt

                     Benesight as the TPA of Saia's medical plan. SCST and Saia
                     shall solely be responsible for the future prosecution of
                     any claim against Benesight and SCST and Saia shall be the
                     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 Litigation
                     Expenses"). Amounts received by SCST or Saia as 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
                     of Action Express, Inc. (merged into Saia effective March
                     4, 2001) on November 3, 1998, future sums are due both Dan
                     and David Fulkerson in the form of payments under the terms
                     of their non-compete agreements through January 31, 2006
                     and January 31, 2005, respectively. The responsibility for
                     all such payments after the Distribution shall rest with
                     SCST and/or Saia, and SCST shall indemnify and hold Yellow
                     harmless for all damages, payments, costs and expenses
                     incurred by Yellow after the Distribution Date which relate
                     in any manner to the Action Express acquisition or claims
                     for damages from the prior owners of Action Express
                     allegedly arising out of said acquisition in accordance
                     with Section 4.3.

           2.6.5     Jevic Executive Employment and Severance Agreements. In
                     connection with the acquisition by Yellow of Jevic on July
                     9, 1999, Yellow and Jevic entered into employment
                     agreements (the "Jevic Employment Agreements") with certain
                     senior officers of Jevic, which employment agreements
                     incorporated by reference severance agreements previously
                     entered into between said senior officers and Jevic. The
                     responsibility for any payments under the Jevic Employment
                     Agreements after the Distribution Date shall rest with SCST
                     and Jevic, and SCST shall indemnify and hold Yellow
                     harmless for all damages, payments, costs and expenses
                     incurred by Yellow after the Distribution Date which relate
                     in any manner to claims for damages or payments under the
                     Jevic Employment Agreements in accordance with Section 4.3.

                                   ARTICLE III

                         REPRESENTATIONS AND WARRANTIES


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

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

           (b)       Authority and Status. Yellow has full power and authority
                     to execute and deliver this Agreement and the Tax Sharing
                     Agreement, to perform its obligations hereunder and under
                     the Tax Sharing Agreement, and to consummate the
                     transactions contemplated hereby and under the Tax Sharing
                     Agreement without the necessity of any act or consent of
                     any other person. Yellow has taken all necessary and
                     appropriate corporate action, including obtaining all
                     necessary board consents, with respect to the execution,
                     delivery and performance of this Agreement and the Tax
                     Sharing Agreement. This Agreement and the Tax Sharing
                     Agreement to be executed, delivered and performed by Yellow
                     in connection herewith constitute or will, when 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.

                     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

                     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

                     limitation, the consummation of the transactions
                     contemplated hereby and thereby will conflict with or

                     of the Certificate of Incorporation or By-laws, as amended

                                   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



<PAGE>


                                      -18-

information 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


<PAGE>


                                      -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


<PAGE>


                                      -20-


employing 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

                               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.

       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
