Dear Sirs and Mesdames:


          Overnite Corporation, a Virginia corporation (the "COMPANY"), proposes
to issue and sell to the several Underwriters, (as defined below)
________________ shares of its Common Stock, par value $.01 per share (the "FIRM
SHARES").

          It is understood that, subject to the conditions hereinafter stated,
____________ Firm Shares (the "U.S. FIRM SHARES") will be sold to the several
U.S. Underwriters named in Schedule I hereto (the "U.S. UNDERWRITERS") in
connection with the offering and sale of such U.S. Firm Shares in the United
States and Canada to United States and Canadian Persons (as such terms are
defined in the Agreement Between U.S. and International Underwriters of even
date herewith), and __________ Firm Shares (the "INTERNATIONAL SHARES") will be
sold to the several International Underwriters named in Schedule II hereto (the
"INTERNATIONAL UNDERWRITERS") in connection with the offering and sale of such
International Shares outside the United States and Canada to persons other than
United States and Canadian Persons.  Morgan Stanley & Co. Incorporated, Credit
Suisse First Boston Corporation, Donaldson, Lufkin & Jenrette Securities
Corporation and Merrill Lynch, Pierce, Fenner & Smith Incorporated shall act as
representatives (the "U.S. REPRESENTATIVES") of the several U.S. Underwriters,
and Morgan Stanley & Co. International Limited, Credit Suisse First Boston
(Europe) 
<PAGE>
 
Limited, Donaldson, Lufkin & Jenrette International and Merrill Lynch
International shall act as representatives (the "INTERNATIONAL REPRESENTATIVES")
of the several International Underwriters.  The U.S. Underwriters and the
International Underwriters are hereinafter collectively referred to as the
Underwriters.

          The Company also proposes to issue and sell to the several U.S.
Underwriters not more than an additional __________  shares of its Common Stock,
par value $.01 per share (the "ADDITIONAL SHARES"), if and to the extent that
the U.S. Representatives shall have determined to exercise, on behalf of the
U.S. Underwriters, the right to purchase such shares of common stock granted to
the U.S. Underwriters in Section 3 hereof.  The Firm Shares and the Additional
Shares are hereinafter collectively referred to as the "SHARES".  The shares of
Common Stock, par value $.01 per share, of the Company to be outstanding after
giving effect to the sales contemplated hereby are hereinafter referred to as
the "COMMON STOCK".

          The Company has filed with the Securities and Exchange Commission (the
"COMMISSION") a registration statement relating to the Shares.  The registration
statement contains two prospectuses to be used in connection with the offering
and sale of the Shares:  the U.S. prospectus, to be used in connection with the
offering and sale of Shares in the United States and Canada to United States and
Canadian Persons, and the international prospectus, to be used in connection
with the offering and sale of Shares outside the United States and Canada to
persons other than United States and Canadian Persons.  The international
prospectus is identical to the U.S. prospectus except for the outside front
cover page.  The registration statement as amended at the time it becomes
effective, including the information (if any) deemed to be part of the
registration statement at the time of effectiveness pursuant to Rule 430A under
the Securities Act of 1933, as amended (the "SECURITIES ACT"), is hereinafter
referred to as the "REGISTRATION STATEMENT"; the U.S. prospectus and the
international prospectus in the respective forms first used to confirm sales of
Shares are hereinafter collectively referred to as the "PROSPECTUS".  If the
Company has filed an abbreviated registration statement to register additional
shares of Common Stock pursuant to Rule 462(b) under the Securities Act (the
"RULE 462 REGISTRATION STATEMENT"), then any reference herein to the term
"Registration Statement" shall be deemed to include such Rule 462 Registration
Statement.

          In connection with the offering of the Shares contemplated hereby, the
Company, Union Pacific Corporation, a Utah corporation ("UPC"), Overnite
Holding, Inc., a 

                                       2

Transportation Company, a Virginia corporation and wholly owned subsidiary of
OHI ("OTC"), have entered into the transactions described in the Prospectus
under the caption "The Acquisition". Such transactions are referred to herein as
the "ACQUISITION".

          1.   Representations and Warranties of the Company, OHI and OTC.  The
Company, OHI and OTC, jointly and severally, represent and warrant to and agree

          (a)  The Registration Statement has become effective; no stop order
     suspending the effectiveness of the Registration Statement is in effect,
     and no proceedings for such purpose are pending before or threatened by the
     Commission.

          (b)  (i)  The Registration Statement, when it became effective, did
     not contain and, as amended or supplemented, if applicable, will not

     material adverse effect on the Company, OHI and OTC, taken as a whole.

               (viii)  the statements (A) in the Prospectus under the captions
          "Agreements with Union Pacific Corporation", "Description of Capital
          Stock" and "Underwriters", to the extent such section summarizes the
          terms of this Agreement, and (B) in the Registration Statement in
          Items 14 and 15, in each case insofar as such statements constitute
          summaries of the legal matters, documents or proceedings referred to
          therein, fairly present the information called for with respect to
          such legal matters, documents and proceedings and fairly summarize the
          matters referred to therein;
 
               (ix) the Company is not and, after giving effect to the offering
          and sale of the Shares and the application of the proceeds thereof as
          described in the Prospectus, will not be an "investment company" as
          such term is defined in the Investment Company Act of 1940, as
          amended;

               (x) each of the Intercompany Agreements has been duly authorized
          by the Company, OHI and OTC, and when executed and delivered by them,
          each will be a legal, valid and binding agreement of the Company, OHI
          and OTC enforceable against them in accordances with its respective
          terms, subject, as to enforcement, to bankruptcy, insolvency,
          reorganization and other laws of general applicability relating to or
          affecting creditors' rights and to general equitable principles; and

               (xi) such counsel (A) is of the opinion that the Registration
          Statement and Prospectus (except for financial statements and
          schedules and other financial and statistical data included therein as
          to which such counsel need not express any opinion) comply as to form
          in all material respects with the Securities Act and the applicable
          rules and regulations of the Commission thereunder, (B) has no reason
          to believe that (except for financial statements and schedules and
          other financial and statistical data as to which such counsel need not
          express any belief) the Registration Statement and the prospectus
          included therein at the time the Registration Statement became
          effective contained any untrue statement of a material fact or omitted
          to state a material fact required to be stated therein or necessary to
          make the statements therein not misleading and (C) has no reason to
          believe that (except for financial statements and schedules and other
          financial and statistical data as to which such counsel need not
          express any belief) the

                                       16
<PAGE>
 
          Prospectus contains any untrue statement of a material fact or omits
          to state a material fact necessary in order to make the statements
          therein, in the light of the circumstances under which they were made,
          not misleading.

               (xii)  The Registration Statement became effective under the
          Securities Act on [        ], 1998, and thereupon the offering of the
          Shares as contemplated by the Prospectus became registered under the
          Securities Act; to our knowledge, no stop order suspending the
          effectiveness of the Registration Statement has been issued and no
          proceedings for that purpose have been instituted or are pending or
          contemplated under the Securities Act.

          (d)  The Underwriters shall have received on the Closing Date an
     opinion of the Senior Vice President and General Counsel or Assistant
     General Counsel of UPC or other counsel satisfactory to the U.S.
     Representatives, dated the Closing Date, to the effect that:

               (i)   UPC has good and valid title to the stock of OHI, free and
          clear of all liens, encumbrances, equities or claims;
 
               (ii)  this Agreement has been duly authorized, executed and
          delivered by UPC and OHI;

               (iii) the execution and delivery by UPC of, and the performance
          by UPC of its obligations under, this Agreement will not contravene
          any provision of applicable law or the certificate of incorporation or
          by-laws of UPC or, to such counsel's knowledge, any agreement or other
          instrument binding upon UPC or any of its subsidiaries (other than OHI
          or OTC or any of its subsidiaries) that is material to UPC and its
          subsidiaries, taken as a whole, or, to such counsel's knowledge, any
          judgment, order or decree of any governmental body, agency or court
          having jurisdiction over UPC or any of its subsidiaries (other than
          OHI or OTC or any of its subsidiaries), and no consent, approval,
          authorization or order of, or qualification with, any governmental
          body or agency is required for the performance by UPC of its
          obligations under this Agreement, except (A) such as have been
          obtained under the Securities Act, and (B) such as may be required by
          the securities or Blue Sky laws 

                                       17

          of the various states in connection with the offer and sale of the
          Shares by the U.S. Underwriters;
 
               (iv)   the statements in the Prospectus under the caption
          "Agreements with Union Pacific Corporation" insofar as such statements
          constitute summaries of the documents referred to therein, fairly
          present the information called for with respect to such documents and
          fairly summarize the matters referred to therein;
 
              (v)     each of the Intercompany Agreements has been duly
          authorized, executed and delivered by UPC and is a legal, valid and
          binding agreement of UPC enforceable against it in accordance with its
          terms, subject, as to enforcement, to bankruptcy, insolvency,
          reorganization and other laws of general applicability relating to or
          affecting creditors' rights and to general equitable principles;
 
               (vi)   pursuant to the Stock Purchase and Indemnification
          Agreement, upon the closing of the Acquisition, UPC will transfer all
          of the capital stock of OHI to the Company free and clear of all
          liens, encumbrances, equities or claims on the capital stock of OHI or
          OTC arising through UPC; and
 
               (vii)  (A) such counsel is of the opinion that the Registration
          Statement, as of its effective date, and the Prospectus, as of its
          date and as of the date hereof, appeared on their face to be
          appropriately responsive in all material respects to the requirements
          of the Securities Act and the applicable rules and regulations of the
          Commission thereunder, (B) nothing has come to the attention of such
          counsel in the course of his participation in the preparation of the
          Registration Statement and Prospectus that caused him to believe that
          the Registration Statement, as of its effective date, or the
          Prospectus, as of its date and as of the date hereof, contain or
          contained any untrue statement of a material fact or omitted to state
          any material fact required to be stated therein or necessary to make
          the statements therein not misleading.

          (e)  The Underwriters shall have received on the Closing Date an
     opinion of the General Counsel of OTC or other counsel satisfactory to the
     U.S. Representatives, dated the Closing Date, to the effect that:

                                       18
<PAGE>
 
               (i) the statements in the Prospectus under the captions "Risk
          Factors--Disputes with Labor Organizations" (second and third
          paragraphs only) and "Business--Employees" (second paragraph only),
          "Risk Factors--Possible Adverse Effect of Governmental Policy and
          Regulations" (second paragraph only) and "Business--Environmental
          Regulation," insofar as such statements constitute summaries of the
          legal matters, documents or proceedings referred to therein, fairly
          present the information called for with respect to such legal matters,
          documents and proceedings and fairly summarize the matters referred to
          therein; and

               (ii) after due inquiry, such counsel does not know of any legal
          or governmental proceedings pending or threatened to which the
          Company, OHI or OTC or any of its subsidiaries is a party or to which
          any of the properties of the Company, OHI or OTC or any of its
          subsidiaries is subject that are required to be described in the
          Registration Statement or the Prospectus and are not so described or
          of any statutes, regulations, contracts or other documents that are
          required to be described in the Registration Statement or the
          Prospectus or to be filed as exhibits to the Registration Statement
          that are not described or filed as required.

          (f)  The Underwriters shall have received on the Closing Date an
     opinion of Richards Layton & Finger, Delaware counsel to the Company, dated
     the Closing Date, to the effect that:

               (i)   the outstanding shares of common stock of OHI have been
          duly authorized and are validly issued, fully paid and non-assessable;

               (ii)  OHI has good and valid title to the stock of OTC, free and
          clear of all liens, encumbrances, equities or claims;

               (iii) this Agreement has been duly authorized, executed and
          delivered by OHI; and

               (iv)  the execution and delivery by OHI of, and the performance
          by OHI of its obligations under, this Agreement will not contravene
          any provision of applicable law or the certificate of incorporation or
          by-laws of OHI.

          (g)  The Underwriters shall have received on the Closing Date an
     opinion of Cravath, Swaine & Moore, counsel for the Underwriters, dated the
     Closing Date, covering the matters referred to in Sections 6(c)(viii) (but
     only as to the statements in the Prospectus under "Description of Capital
     Stock" and "Underwriters") and 6(c)(xi) above.

          With respect to the opinions covering matters stated in Section
     6(c)(xi) above, Hunton & Williams, UPC counsel and Cravath, Swaine & Moore
     may state that their opinion and belief are based upon their participation
     in the preparation of the Registration Statement and Prospectus and any
     amendments or supplements thereto and review and discussion of the contents
     thereof, but are without independent check or verification, except as
     specified.

          The opinion of (i) Hunton & Williams described in Section 6(c) above,
     (ii) the Senior Vice President and General Counsel or Assistant General
     Counsel of UPC or other counsel satisfactory to the U.S. Representatives
     described in Section 6(d) above and (iii) the opinion of the General
     Counsel of OTC or other counsel satisfactory to the U.S. Representatives
     described in Section 6(e) above shall be rendered to the Underwriters at
     the request of the Company, UPC or OTC, as the case may be and shall so
     state therein.

          (g)  The Underwriters shall have received, on each of the date hereof
     and the Closing Date, a letter dated the date hereof or the Closing Date,
     as the case may be, in form and substance satisfactory to the Underwriters,
     from Deloitte & Touche LLP, independent public accountants, containing
     statements and information of the type ordinarily included in accountants'
     "comfort letters" to underwriters with respect to the financial statements
     and certain financial information contained in the Registration Statement
     and the Prospectus; provided that the letter delivered on the Closing Date
     shall use a "cut-off date" not earlier than the date hereof.

          (h)  The "lock-up" agreements, each substantially in the form of
     Exhibit A hereto, between you and certain officers and directors of the
     Company relating to sales and certain other dispositions of shares of
     Common Stock or certain other securities, delivered to you on or before the
     date hereof, shall be in full force and effect on the Closing Date.

          (i)  The several obligations of the U.S. Underwriters to purchase
     Additional Shares hereunder 

                                       20
<PAGE>
 
     are subject to the delivery to the U.S. Representatives on the Option
     Closing Date of such documents as they may reasonably request with respect
     to the good standing of the Company, the due authorization and issuance of
     the Additional Shares and other matters related to the issuance of the
     Additional Shares.

          7.  Covenants of the Company and UPC.  In further consideration of the
agreements of the Underwriters herein contained, the Company and, with respect
to paragraph (f) below, UPC, covenant with each Underwriter as follows:

          (a)  To furnish to you, without charge, five signed copies of the
     Registration Statement (including exhibits thereto) and for delivery to
     each other Underwriter a conformed copy of the Registration Statement
     (without exhibits thereto) and to furnish to you in New York City, without
     charge, as soon as practicable on the business day next succeeding the date
     of this Agreement and during the period mentioned in Section 7(c) below, as
     many copies of the Prospectus and any supplements and amendments thereto or
     to the Registration Statement as you may reasonably request.

          (b)  Before amending or supplementing the Registration Statement or
     the Prospectus, to furnish to you a copy of each such proposed amendment or
     supplement and not to file any such proposed amendment or supplement to
     which you reasonably object, and to file with the Commission within the
     applicable period specified in Rule 424(b) under the Securities Act any
     prospectus required to be filed pursuant to such Rule.

          (c)  If, during such period after the first date of the public
     offering of the Shares as in the opinion of counsel for the Underwriters
     the Prospectus is required by law to be delivered in connection with sales
     by an Underwriter or dealer, any event shall occur or condition exist as a
     result of which it is necessary to amend or supplement the Prospectus in
     order to make the statements therein, in the light of the circumstances
     when the Prospectus is delivered to a purchaser, not misleading, or if, in
     the opinion of counsel for the Underwriters, it is necessary to amend or
     supplement the Prospectus to comply with applicable law, forthwith to
     prepare, file with the Commission and furnish, at its own expense, to the
     Underwriters and to the dealers (whose names and addresses you will furnish
     to the Company) to which Shares may have been sold by you on behalf of the
     Underwriters and to any other dealers upon request, either amendments or
     supplements to the Prospectus so that the statements in the Prospectus as
     so amended or supplemented will not, in 

                                       21
<PAGE>
 
     the light of the circumstances when the Prospectus is delivered to a
     purchaser, be misleading or so that the Prospectus, as amended or
     supplemented, will comply with law.

          (d)  To endeavor to qualify the Shares for offer and sale under the
     securities or Blue Sky laws of such jurisdictions as you shall reasonably
     request.

     to you as soon as practicable an earning statement covering the twelve-
     month period ending September 30, 1999 that satisfies the provisions of
     Section 11(a) of the Securities Act and the rules and regulations of the
     Commission thereunder.

          (f) Whether or not the transactions contemplated in this Agreement are
     consummated or this Agreement is terminated, to pay or cause to be paid all
     expenses incident to the performance of its obligations under this
     Agreement, including: (i) the fees, disbursements and expenses of the
     Company's counsel and the Company's accountants in connection with the
     registration and delivery of the Shares under the Securities Act and all
     other fees or expenses in connection with the preparation and filing of the
     Registration Statement, any preliminary prospectus, the Prospectus and
     amendments and supplements to any of the foregoing, including all printing
     costs associated therewith, and the mailing and delivering of copies
     thereof to the Underwriters and dealers, in the quantities hereinabove
     specified, (ii) all costs and expenses related to the transfer and delivery
     of the Shares to the Underwriters, including any transfer or other taxes
     payable thereon, (iii) the cost of printing or producing any Blue Sky or
     Legal Investment memorandum in connection with the offer and sale of the
     Shares under state securities laws and all expenses in connection with the
     qualification of the Shares for offer and sale under state securities laws
     as provided in Section 7(d) hereof, including filing fees and the
     reasonable fees and disbursements of counsel for the Underwriters in
     connection with such qualification and in connection with the Blue Sky or
     Legal Investment memorandum, (iv) all filing fees and the reasonable fees
     and disbursements of counsel to the Underwriters incurred in connection
     with the review and qualification of the offering of the Shares by the
     National Association of Securities Dealers, Inc., (v) all fees and expenses
     in connection with the preparation and filing of the registration statement
     on Form 8-A relating to the Common Stock and all costs and expenses
     incident to listing the Shares on the Nasdaq 

                                       22
<PAGE>
 
     National Market, (vi) the cost of printing certificates representing the
     Shares, (vii) the costs and charges of any transfer agent, registrar or
     depositary, (viii) the costs and expenses of the Company relating to
     investor presentations on any "road show" undertaken in connection with the
     marketing of the offering of the Shares, including, without limitation,
     expenses associated with the production of road show slides and graphics,
     fees and expenses of any consultants engaged in connection with the road
     show presentations with the prior approval of the Company, travel and
     lodging expenses of the representatives and officers of the Company and any
     such consultants, and the cost of any aircraft chartered in connection with
     the road show, (ix) all expenses similar to those set forth in (i) through
     (viii) of this Section 7 in connection with any offer and sale of the
     Shares outside of the United States, including filing fees and the
     reasonable fees and disbursements of counsel for the Underwriters in
     connection with offers and sales outside of the United States, (x) all
     other costs and expenses incident to the performance of the obligations of
     the Company hereunder for which provision is not otherwise made in this
     Section. It is understood, however, that except as provided in this
     Section, Section 8 entitled "Indemnity and Contribution," and the last
     paragraph of Section 10 below, the Underwriters will pay all of their costs
     and expenses, including fees and disbursements of their counsel, stock
     transfer taxes payable on resale of any of the Shares by them and any
     advertising expenses connected with any offers they may make.

          8.  Indemnity and Contribution.  (a) (i)  The Company agrees to
indemnify and hold harmless each Underwriter and each person, if any, who
controls any Underwriter within the meaning of either Section 15 of the
Securities Act or Section 20 of the Securities Exchange Act of 1934, as amended
(the "EXCHANGE ACT"), from and against any and all losses, claims, damages and
liabilities (including, without limitation, any legal or other expenses
reasonably incurred in connection with defending or investigating any such
action or claim) caused by any untrue statement or alleged untrue statement of a
material fact contained in the Registration Statement or any amendment thereof,
any preliminary prospectus or the Prospectus (as amended or supplemented if the
Company shall have furnished any amendments or supplements thereto), or caused
by any omission or alleged omission to state therein a material fact required to
be stated therein or necessary to make the statements therein not misleading,
except insofar as such losses, claims, damages or liabilities are caused by any
such untrue statement or omission or alleged untrue 

                                       23
<PAGE>
 
statement or omission based upon information relating to any Underwriter
furnished to the Company in writing by such Underwriter through you expressly
for use therein.

          (b)  UPC agrees to indemnify and hold harmless each Underwriter and
each person, if any, who controls any Underwriter within the meaning of either
Section 15 of the Securities Act or Section 20 of the Securities Exchange Act of
1934, as amended (the "EXCHANGE ACT"), from and against any and all losses,
claims, damages and liabilities (including, without limitation, any legal or
other expenses reasonably incurred in connection with defending or investigating
any such action or claim) caused by any untrue statement or alleged untrue
statement of a material fact contained in the Registration Statement or any
amendment thereof, any preliminary prospectus or the Prospectus (as amended or
supplemented if the Company shall have furnished any amendments or supplements
thereto) or caused by any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, but, in each case, only insofar as such statement or
omission relates to the UPC Information.

          (c)  Each Underwriter agrees, severally and not jointly, to indemnify
and hold harmless the Company, its directors, its officers who sign the
Registration Statement, UPC and each person, if any, who controls the Company or
UPC within the meaning of either Section 15 of the Securities Act or Section 20
of the Exchange Act to the same extent as the foregoing indemnity from the
Company and UPC to such Underwriter, but only with reference to information
relating to such Underwriter furnished to the Company or UPC in writing by such
Underwriter through you expressly for use in the Registration Statement, any
preliminary prospectus, the Prospectus or any amendments or supplements thereto.

          (d)  In case any proceeding (including any governmental investigation)
shall be instituted involving any person in respect of which indemnity may be
sought pursuant to Section 8(a), 8(b) or 8(c), such person (the "INDEMNIFIED
PARTY") shall promptly notify the person against whom such indemnity may be
sought (the "INDEMNIFYING PARTY") in writing and the indemnifying party may, and
upon request of the indemnified party, shall, retain counsel reasonably
satisfactory to the indemnified party to represent the indemnified party and any
others the indemnifying party may designate in such proceeding and shall pay the
fees and disbursements of such counsel related to such proceeding.  In any such
proceeding, any indemnified party shall have the right to retain its own
counsel, but the fees and expenses of such counsel shall be at the expense of
such indemnified party unless (i) the 

                                       24
<PAGE>
 
indemnifying party and the indemnified party shall have mutually agreed to the
retention of such counsel or (ii) the named parties to any such proceeding
(including any impleaded parties) include both the indemnifying party and the
indemnified party and representation of both parties by the same counsel would
be inappropriate due to actual or potential differing interests between them. It
is understood that the indemnifying party shall not, in respect of the legal
expenses of any indemnified party in connection with any proceeding or related
proceedings in the same jurisdiction, be liable for the fees and expenses of
more than one separate firm (in addition to any local counsel) for all such
indemnified parties and that all such fees and expenses shall be reimbursed as
they are incurred. The indemnifying party shall not be liable for any settlement
of any proceeding effected without its written consent, but if settled with such
consent or if there be a final judgment for the plaintiff, the indemnifying
party agrees to indemnify the indemnified party from and against any loss or
liability by reason of such settlement or judgment. No indemnifying party shall,
without the prior written consent of the indemnified party, effect any
settlement of any pending or threatened proceeding in respect of which any
indemnified party is or could have been a party and indemnity could have been
sought hereunder by such indemnified party, unless such settlement includes an
unconditional release of such indemnified party from all liability on claims
that are the subject matter of such proceeding.

          (e)  To the extent the indemnification provided for in Section 8(a),
8(b) or 8(c) is unavailable to an indemnified party or insufficient in respect
of any losses, claims, damages or liabilities referred to therein, then each
indemnifying party under such paragraph, in lieu of indemnifying such
indemnified party thereunder, shall contribute to the amount paid or payable by
such indemnified party as a result of such losses, claims, damages or
liabilities (i) in such proportion as is appropriate to reflect the relative
benefits received by the indemnifying party or parties on the one hand and the
indemnified party or parties on the other hand from the offering of the Shares
or (ii) if the allocation provided by clause 8(e)(i) above is not permitted by
applicable law, in such proportion as is appropriate to reflect not only the
relative benefits referred to in clause 8(e)(i) above but also the relative
fault of the indemnifying party or parties on the one hand and of the
indemnified party or parties on the other hand in connection with the statements
or omissions that resulted in such losses, claims, damages or liabilities, as
well as any other relevant equitable considerations.  The relative benefits
received by the Company and UPC on the one hand and the Underwriters on the
other hand in connection with the 

                                       25
<PAGE>
 
offering of the Shares shall be deemed to be in the same respective proportions
as the net proceeds from the offering of the Shares (before deducting expenses)
received by the Company and the total underwriting discounts and commissions
received by the Underwriters, in each case as set forth in the table on the
cover of the Prospectus, bear to the aggregate Public Offering Price of the
Shares. The relative fault of the Company and UPC on the one hand and the
Underwriters on the other hand shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Company and UPC or by the Underwriters and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission. The Underwriters' respective obligations to
contribute pursuant to this Section 8 are several in proportion to the
respective number of Shares they have purchased hereunder, and not joint.

          (f) The Company, UPC and the Underwriters agree that it would not be
just or equitable if contribution pursuant to this Section 8 were determined by
pro rata allocation (even if the Underwriters were treated as one entity for
such purpose) or by any other method of allocation that does not take account of
the equitable considerations referred to in Section 8(e).  The amount paid or
payable by an indemnified party as a result of the losses, claims, damages and
liabilities referred to in the immediately preceding paragraph shall be deemed
to include, subject to the limitations set forth above, any legal or other
expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim.  Notwithstanding the
provisions of this Section 8, no Underwriter shall be required to contribute any
amount in excess of the amount by which the total price at which the Shares
underwritten by it and distributed to the public were offered to the public
exceeds the amount of any damages that such Underwriter has otherwise been
required to pay by reason of such untrue or alleged untrue statement or omission
or alleged omission.  No person guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation.  The remedies provided for in this Section 8 are not
exclusive and shall not limit any rights or remedies which may otherwise be
available to any indemnified party at law or in equity.

          (g)  The indemnity and contribution provisions contained in this
Section 8 and the representations, warranties and other statements of the
Company and UPC contained in this Agreement shall remain operative and in 

                                       26
<PAGE>
 
full force and effect regardless of (i) any termination of this Agreement, (ii)
any investigation made by or on behalf of any Underwriter or any person
controlling any Underwriter or by or on behalf of the Company, UPC, any of their
officers or directors or any person controlling the Company or UPC and (iii)
acceptance of and payment for any of the Shares.

          9.  Termination.  This Agreement shall be subject to termination by
notice given by you to the Company, if (a) after the execution and delivery of
this Agreement and prior to the Closing Date (i) trading generally shall have
been suspended or materially limited on or by, as the case may be, any of the
New York Stock Exchange, the American Stock Exchange, the National Association
of Securities Dealers, Inc., the Chicago Board of Options Exchange, the Chicago
Mercantile Exchange or the Chicago Board of Trade, (ii) trading of any
securities of the Company shall have been suspended on any exchange or in any
over-the-counter market, (iii) a general moratorium on commercial banking
activities in New York shall have been declared by either Federal or New York
State authorities or (iv) there shall have occurred any outbreak or escalation
of hostilities or any change in financial markets or any calamity or crisis
that, in your judgment, is material and adverse and (b) in the case of any of
the events specified in clauses 8(a)(i) through 8(a)(iv), such event, singly or
together with any other such event, makes it, in your judgment, impracticable to
market the Shares on the terms and in the manner contemplated in the Prospectus.

          10.  Effectiveness; Defaulting Underwriters.  This Agreement shall
become effective upon the execution and delivery hereof by the parties hereto.

          If, on the Closing Date or the Option Closing Date, as the case may
be, any one or more of the Underwriters shall fail or refuse to purchase Shares
that it has or they have agreed to purchase hereunder on such date, and the
aggregate number of Shares which such defaulting Underwriter or Underwriters
agreed but failed or refused to purchase is not more than one-tenth of the
aggregate number of the Shares to be purchased on such date, the other
Underwriters shall be obligated severally in the proportions that the number of
Firm Shares set forth opposite their respective names in Schedule I or Schedule
II bears to the aggregate number of Firm Shares set forth opposite the names of
all such non-defaulting Underwriters, or in such other proportions as you may
specify, to purchase the Shares which such defaulting Underwriter or
Underwriters agreed but failed or refused to purchase on such date; provided
that in no event shall the number of Shares that any Underwriter has agreed to
purchase pursuant to this Agreement be increased 

                                       27
<PAGE>
 
pursuant to this Section 10 by an amount in excess of one-ninth of such number
of Shares without the written consent of such Underwriter. If, on the Closing
Date, any Underwriter or Underwriters shall fail or refuse to purchase Firm
Shares and the aggregate number of Firm Shares with respect to which such
default occurs is more than one-tenth of the aggregate number of Firm Shares to
be purchased, and arrangements satisfactory to you and the Company for the
purchase of such Firm Shares are not made within 36 hours after such default,
this Agreement shall terminate without liability on the part of any non-
defaulting Underwriter or the Company. In any such case either you or the
Company shall have the right to postpone the Closing Date, but in no event for
longer than seven days, in order that the required changes, if any, in the
Registration Statement and in the Prospectus or in any other documents or
arrangements may be effected. If, on the Option Closing Date, any Underwriter or
Underwriters shall fail or refuse to purchase Additional Shares and the
aggregate number of Additional Shares with respect to which such default occurs
is more than one-tenth of the aggregate number of Additional Shares to be
purchased, the non-defaulting Underwriters shall have the option to (i)
terminate their obligation hereunder to purchase Additional Shares or (ii)
purchase not less than the number of Additional Shares that such non-defaulting
Underwriters would have been obligated to purchase in the absence of such
default. Any action taken under this paragraph shall not relieve any defaulting
Underwriter from liability in respect of any default of such Underwriter under
this Agreement.

          If this Agreement shall be terminated by the Underwriters, or any of
them, because of any failure or refusal on the part of the Company or UPC to
comply with the terms or to fulfill any of the conditions of this Agreement, or
if for any reason the Company or UPC shall be unable to perform its obligations
under this Agreement, other than due to a default on the part of any Underwriter
or the exercise of the Underwriters' right of termination under Section 9, the
Company and UPC agree, jointly and severally, to reimburse the Underwriters or
such Underwriters as have so terminated this Agreement with respect to
themselves, for all out-of-pocket expenses (including the fees and disbursements
of their counsel) reasonably incurred by such Underwriters in connection with
this Agreement or the offering contemplated hereunder.

          11.  Counterparts.  This Agreement may be signed in two or more
counterparts, each of which shall be an original, with the same effect as if the
signatures thereto and hereto were upon the same instrument.

                                       28

          12.  Applicable Law.  This Agreement shall be governed by and
construed in accordance with the internal laws of the State of New York.

          13.  Headings.  The headings of the sections of this Agreement have
been inserted for convenience of reference only and shall not be deemed a part
of this Agreement.

Dear Sirs and Mesdames:

          The undersigned understands that Morgan Stanley & Co. Incorporated
("MORGAN STANLEY") and Morgan Stanley & Co. International Limited ("MSIL")
propose to enter into an Underwriting Agreement (the "UNDERWRITING AGREEMENT")
with Overnite Corporation, a Virginia corporation (the "COMPANY") providing for
the public offering (the "PUBLIC OFFERING") by the several Underwriters,
including Morgan Stanley and MSIL (the "UNDERWRITERS") of 33,600,000 shares (the
"SHARES") of the Common Stock, par value $.01 per share, of the Company (the
"COMMON STOCK").

          To induce the Underwriters that may participate in the Public Offering
to continue their efforts in connection with the Public Offering, the
undersigned hereby agrees that, without the prior written consent of Morgan
Stanley on behalf of the Underwriters, it will not, during the period commencing
on the date hereof and ending 180 days after the date of the Prospectus (as
defined in the Underwriting Agreement), except with respect to employee stock
option plans in effect as of the date of the Underwriting Agreement, (1) offer,
pledge, sell, contract to sell, sell any option or 

                                       33
<PAGE>
 
contract to purchase, purchase any option or contract to sell, grant any option,
right or warrant to purchase, lend, or otherwise transfer or dispose of,
directly or indirectly, any shares of Common Stock or any securities convertible
into or exercisable or exchangeable for Common Stock, or (2) enter into any swap
or other arrangement that transfers to another, in whole or in part, any of the
economic consequences of ownership of the Common Stock, whether any such
transaction described in clause (1) or (2) above is to be settled by delivery of
Common Stock or such other securities, in cash or otherwise. The foregoing
sentence shall not apply to (a) the sale of any Shares to the Underwriters
pursuant to the Underwriting Agreement or (b) transactions relating to shares of
Common Stock or other securities acquired in open market transactions after the
completion of the Public Offering. In addition, the undersigned agrees that,
without the prior written consent of Morgan Stanley on behalf of the
Underwriters, it will not, during the period commencing on the date hereof and
ending 180 days after the date of the Prospectus, make any demand for or
exercise any right with respect to, the registration of any shares of Common
Stock or any security convertible into or exercisable or exchangeable for Common
Stock.

          Whether or not the Public Offering actually occurs depends on a number
of factors, including market conditions. Any Public Offering will only be made
pursuant to an Underwriting Agreement, the terms of which are subject to
negotiation between the Company and the Underwriters.


                              Very truly yours,

               --------------------------------------------------

Gentlemen:

  We are acting as counsel for Overnite Corporation (the "Company") in
connection with its Registration Statement on Form S-1, and any amendments
thereto (the "Registration Statement"), as filed with the Securities and
Exchange Commission, with respect to 36,960,000 shares of the Company's Common
Stock, $0.01 par value per share (the "Shares"), which are proposed to be
offered and sold by the Company as described in the Registration Statement.  In
connection with the filing of the Registration Statement, you have requested our
opinion concerning certain corporate matters.

  In rendering this opinion, we have relied upon, among other things, our
examination of such records of the Company and certificates of its officers and
of public officials as we have deemed necessary.

  Based upon the foregoing, we are of the opinion that:

  1. The Company is a corporation duly incorporated, validly existing and in
good standing under the laws of the Commonwealth of Virginia.

  2.  The Shares covered by the Registration Statement have been duly authorized
and, when such shares have been issued as described in the Registration
Statement, will be legally issued, fully paid and non-assessable.

  We consent to the filing of this opinion with the Securities and Exchange
Commission as an exhibit to the Registration Statement and to the statement made
in reference to this firm under the caption "Legal Matters" in the Prospectus
included therein.  In giving this consent, we do not admit that we are within
the category of persons whose consent is required by Section 7 of the Securities
Act of 1933 or the rules and regulations promulgated thereunder by the
Securities and Exchange Commission.

Lender pursuant hereto shall be evidenced by a separate Revolving Note.  Each
Revolving Note shall be issued on or before the Effective Date and shall bear
interest for the period from the initial Funding Date thereof until paid in full
on the unpaid principal amount thereof at the rate specified in Section 3.1 of
this Agreement.   Each Lender is hereby authorized to record in the books and
records of such Lender (without making any notation in such Lender's Revolving
Note or any schedule thereto) the amount and Funding Date of each Revolving Loan
made by such Lender, and the amount and date of each payment or prepayment of
any Revolving Loan.  No failure to so record nor any error in so recording shall
affect the obligations of the Borrowers to repay the actual outstanding
principal amount of the Revolving Loans, with interest thereon, as provided in
this Agreement.  The aggregate principal amount of the Revolving Loans shall be
payable on the Maturity Date, unless sooner accelerated pursuant to the terms of
this Agreement.

          Section 2.2  Revolving Loan Borrowing Procedures.
                       ------------------------------------

          (a)  Notice of Revolving Borrowing.  Whenever the Borrowers desire to
               -----------------------------                                   
borrow Revolving Loans under Section 2.1 hereof, the Borrowers shall deliver to
the Agent irrevocable written notice substantially in the form of Exhibit C
(each such notice, a "Borrowing Notice").  In the case of a Revolving Loan
bearing interest at the Base Rate, the Borrowing Notice shall be delivered no
later than 10:00 A.M. (Eastern time) on the Funding Date.  In the case of a
Revolving Loan bearing interest at the Applicable LIBOR Rate, the Borrowing
Notice shall be delivered no later than 10:00 A.M. at least three (3) LIBOR
Business Days prior to the first day of the LIBOR Period as to which such loan
relates, it being understood that the Borrowers' entitlement to request
Revolving Loans bearing interest at the Applicable LIBOR Rate is subject to
compliance with, and the limitations of, Section 3.8(a) (with such modifications
as shall be necessary to reflect that an initial loan, rather than the
conversion of an outstanding loan, is being requested).  The Borrowing Notice
shall specify (i) that the Borrowers wish to effect Revolving Loans, (ii) the
amount of the Revolving Loans thereby requested (which shall not be less than
$3,000,000 and shall be in multiples of $500,000), (iii) the requested Funding
Date of such Revolving Loans, which date shall be a Business Day, and (iv)
whether the requested Revolving Loans will bear interest at the Base Rate or
Applicable LIBOR Rate.  Each Borrowing Notice shall be accompanied by the
officer's certificate contemplated by Section 4.2(d) hereof.  In lieu of
delivering the above-described Borrowing Notice, and only with the consent of 
the Agent in its

                                                                              22
 
<PAGE>
 
sole discretion at such time, the Borrowers may give the Agent telephonic notice
of any such proposed borrowing by the time required under this Section 2.2(a);
provided that, in the event the Agent so consents, such notice shall be
- --------                                                               
confirmed in writing by delivery to the Agent promptly (but in no event later
than 12:00 noon (Eastern time) on the Funding Date of the requested Revolving
Loans) of a Borrowing Notice (it being understood that any such telephonic
notice shall be irrevocable).  Notwithstanding anything contained herein to the
contrary, the Agent, without any notice or other authorization being required,
shall (and is hereby irrevocably instructed by the Borrowers to) effect
Revolving Loans bearing interest at the Base Rate in an amount sufficient to
effect each payment of interest on the Loans due on each Interest Payment Date,
and of each payment of the Facility Fee and the Administrative Fee due on the
applicable Fee Payment Date, in accordance with Section 3.4(a) of this
Agreement, provided that to the extent such payments are greater than the
           --------                                                      
aggregate Lender Availability, such payments shall be effected by a debit to the
Borrowers' Account as provided in Section 3.4(a) hereof.

          (b)  Making of Revolving Loans.  Promptly after receipt of a Borrowing
               -------------------------                                        
Notice under clause (a) of this Section 2.2 (or telephonic notice if the Agent
so consents thereto), the Agent shall notify each Lender by telecopy or telex or
other customary form of teletransmission of the requested borrowing.  Each
Lender shall make the amount of its Revolving Loan available to the Agent in
Dollars and in immediately available funds, not later than 3:00 P.M. (Eastern
time) on the Funding Date specified in the Borrowing Notice.  After the Agent's
receipt of the proceeds of such Revolving Loans from the Lenders, the Agent
shall (unless it shall have learned that any of the conditions precedent set
forth in Section 4.2 hereof have not been satisfied) make the proceeds of such
Revolving Loans available to the Borrowers on such Funding Date and shall
disburse such funds in Dollars to the Borrowers in immediately available funds
by crediting the Borrowers' Account.

          (c)  Failure to Fund by Lender.  Unless the Agent shall have been
               -------------------------                                   
notified by any Lender prior to 12:00 P.M. (Eastern time) on any Funding Date in
respect of Revolving Loans requested under a Borrowing Notice that such Lender
does not intend to make available to the Agent such Lender's Revolving Loan on
such Funding Date, the Agent may assume that such Lender has made such amount
available to the Agent on such Funding Date and the Agent in its sole discretion
may, but shall not be obligated to, make available to the Borrowers a
corresponding amount on such Funding Date. If such corresponding amount is not
in fact made available to the Agent by such Lender on or prior to 3:00 P.M.
(Eastern time) on a Funding Date, such Lender agrees to pay and the Borrowers
agree to repay to the Agent forthwith on demand such corresponding amount
together with interest thereon, for each day from

                                                                              23
<PAGE>
 
the date such amount is made available to the Borrowers until the date such
amount is paid or repaid to the Agent, at (i) in the case of such Lender, the
Federal Funds Rate, and (ii) in the case of the Borrowers, the Base Rate. If
such Lender shall pay to the Agent such corresponding amount, such amount so
paid shall constitute such Lender's Revolving Loan, and if both such Lender and
the Borrowers shall have paid and repaid, respectively, such corresponding
amount, the Agent shall promptly pay over to the Borrowers such corresponding
amount in same day funds, but the Borrowers shall remain obligated for all
interest thereon. Nothing contained in this Section 2.2(b) shall be deemed to
relieve any Lender of its obligation hereunder to make its Revolving Loan on any
Funding Date.

          Section 2.3  Standby Letters of Credit.
                       ------------------------- 

          (a)  Generally.  Subject to and in accordance with the terms and
               ---------                                                  
conditions set forth herein, the Borrowers may request the Issuing Lender, from
time to time during the period commencing on the Effective Date and ending ten
(10) Business Days prior to the Maturity Date, to issue, and subject to the
terms hereof the Issuing Lender shall issue, for the account of the Borrowers,
one or more standby letters of credit (each, a "Standby Letter of Credit")
pursuant to the Issuing Lender's customary letter of credit application;
                                                                        
provided that by entering into this Agreement the Borrowers shall be deemed to
- --------                                                                      
have requested the reissuance, effective as of the Effective Date, of all
Standby Letters of Credit previously issued by the Agent for the account of
Operating Borrower prior to the Effective Date, and such Standby Letters of
Credit shall thereafter be deemed for all purposes to have been issued under
this Agreement as of the Effective Date; provided, further, that the L/C
                                         --------  -------              
Fronting Fee shall not be payable on the Effective Date in respect of such
Standby Letters of Credit.  The aggregate outstanding amount at any time and
from time to time of all Standby Letters of Credit shall not exceed $75,000,000.
The Issuing Lender shall have no obligation to issue any Standby Letter of
Credit if, after giving effect to the issuance thereof, the Total Outstanding
Amount shall then exceed the Aggregate Commitment (it being understood that the
Issuing Lender shall, upon request of the Borrowers, issue a Standby Letter of
Credit in an amount that would, after giving effect to the issuance thereof, not
cause the Aggregate Commitment to be exceeded).

          (b)  Standby Letter of Credit Fees; Maturity.  The Borrowers shall,
               ---------------------------------------                       
among other things, pay to the Issuing Lender for the benefit of the Lenders,
pro rata, on each L/C Fee Payment Date, in arrears, a fee (the "L/C Fee") per
annum (calculated on the basis of a 360 day year and the actual number of days
elapsed), computed by multiplying the Applicable LIBOR Margin for the Fiscal
Quarter immediately preceding the applicable L/C Fee Payment Date by the daily
average of the aggregate of all

                                                                              24
<PAGE>
 
Standby Letters of Credit outstanding during such Fiscal Quarter. Any change in
the Applicable LIBOR Margin resulting from a change in the Consolidated Leverage
Ratio shall be effective five (5) Business Days after receipt of Borrowers'
financial statements reflecting such ratio; provided, however, that if such
                                            --------  ------- 
financial statements are not delivered when due, then the highest Applicable
LIBOR Margin shall apply. In addition to the L/C Fee, the Borrowers shall pay to
the Issuing Lender, for its own account, a L/C Fronting Fee equal to 0.05% of
the amount of the Standby Letter of Credit per annum (calculated on the basis of
a 360 days year and the actual number of days the Standby Letter of Credit will
be outstanding) (the "L/C Fronting Fee"). The L/C Fronting Fee shall be payable
not later than the Fee Payment Date.

          All Standby Letters of Credit issued by the Issuing Lender as
contemplated by this Section 2.3 shall expire no later than the Maturity Date.
Notwithstanding that the Issuing Lender shall have no obligation to issue any
Standby Letter of Credit the expiration date of which shall extend beyond the
Maturity Date, if the expiration date of any Standby Letter of Credit shall in
fact extend beyond the Maturity Date, then on the last Business Day immediately
preceding the Maturity Date, there shall be deemed to have been made Revolving
Loans in the outstanding amount of all Standby Letters of Credit the expiration
date of which shall occur after the Maturity Date, the proceeds of which the
Issuing Lender shall deposit in a collateral account at the Issuing Lender or an
Affiliate thereof in order to collateralize such Standby Letters of Credit,
which collateral account shall bear interest for the account of the Borrowers
based upon investment of the funds as agreed between the Issuing Lender and the
Borrowers.

          (c)  Standby Letter of Credit Request Procedure.  Whenever the
               ------------------------------------------               
Borrowers desire that a Standby Letter of Credit be issued on its behalf, the
Borrowers shall give the Issuing Lender (with copies to be sent to the Agent and
each other Lender) at least three (3) Business Days' prior written notice
therefor.  The execution and delivery of each request for a Standby Letter of
Credit shall be deemed to be a representation and warranty by the Borrowers that
such Standby Letter of Credit may be issued in accordance with, and will not
violate the requirements of, this Section 2.3.  Unless the Issuing Lender has
received notice from the Agent or any Lender before it issues the respective
Standby Letter of Credit that one or more of the conditions specified in Section
4.2 are not then satisfied, or that the issuance of such Standby Letter of
Credit would violate this Section 2.3, then the Issuing Lender may issue the
requested Standby Letter of Credit for the account of the Borrowers in
accordance with the terms of this Agreement and, with respect to any matters not
specifically covered by this Agreement, in accordance with the Issuing Lender's
usual and customary commercial lending practices as in effect from time to time.

                                                                              25

          (d)  Letter of Credit Participations.
               ------------------------------- 

               (i)    Immediately upon the issuance by the Issuing Lender of any
     Standby Letter of Credit, the Issuing Lender shall be deemed to have sold
     and transferred to each Lender (other than the Issuing Lender), and each
     such Lender shall be deemed irrevocably and unconditionally to have
     purchased and received from the Issuing Lender, without recourse or
     warranty, an undivided interest and participation, in proportion to such
     Lender's Pro Rata Share, in such Standby Letter of Credit, each drawing
     made thereunder and the obligations of the Borrowers under this Agreement
     with respect thereto, and any collateral therefor.  Upon any change in a
     Lender's Pro Rata Share of the Revolving Loan Commitment, it is hereby
     agreed that with respect to all outstanding Standby Letters of Credit,
     there shall be an automatic adjustment to the participations pursuant to
     this Section 2.3(d) to reflect the new Pro Rata Share of the Revolving Loan
     Commitment of the assigning and assignee Lenders.

               (ii)   In determining whether to pay under any Standby Letter of
     Credit, the Issuing Lender shall have no obligation relative to the Lenders
     other than to confirm that any documents required to be delivered under
     such Standby Letter of Credit appear to have been delivered and that they
     appear to comply on their face with the requirements of such Standby Letter
     of Credit.  Any action taken or omitted to be taken by the Issuing Lender
     under or in connection with any Standby Letter of Credit, if taken or
     omitted in the absence of gross negligence or willful misconduct, shall not
     create for the Issuing Lender any resulting liability to any Lender.

               (iii)  Upon the request of any Lender, the Issuing Lender shall
     furnish to such Lender copies of any Standby Letter of Credit to which the
     Issuing Lender is party and such other documentation relating to such
     Standby Letter of Credit as may reasonably be requested by such Lender.

               (iv)   As between the Borrowers on the one hand and the Issuing
     Lender and the Lenders on the other hand, the Borrowers assume all risks of
     the acts and omissions of, or misuse of the Standby Letters of Credit by
     the respective beneficiaries of such Standby Letters of Credit. Without
     limiting the generality of the foregoing, neither the Issuing Lender nor
     any other Lender shall be responsible (except in the case of its gross
     negligence or willful misconduct) for the following:

                                                                              26
<PAGE>
 
               (A)  the form, validity, sufficiency, accuracy, genuineness or
          legal effect of any documents submitted by any party in connection
          with the application for and issuance of or any drawing under such
          Standby Letters of Credit, even if it should in fact prove to be in
          any respects invalid, insufficient, inaccurate, fraudulent or forged;

               (B)  the validity or sufficiency of any instrument transferring
          or assigning or purporting to transfer or assign any such Standby
          Letter of Credit or the rights or benefits thereunder or proceeds
          thereof, in whole or in part, which may prove to be invalid or
          ineffective for any reason;

               (C)  failure of the beneficiary of any such Standby Letter of
          Credit to comply fully with conditions required in order to draw upon
          such Standby Letter of Credit, other than material conditions or
          instructions that expressly appear in such Standby Letter of Credit;

               (D)  errors, omissions, interruptions or delays in the
          transmission or delivery of any messages by mail, cable, telegraph,
          telecopier, telex or otherwise, whether or not they are encoded;

               (E)  errors in interpretation of technical terms;

               (F)  any loss or delay in the transmission or otherwise of any
          document required in order to make a drawing under any such Standby
          Letter of Credit or the proceeds thereof;

               (G)  the misapplication by the beneficiary of any such Standby
          Letter of Credit of the proceeds of any drawing of any such Standby
          Letter of Credit; or

               (H)  any consequences arising from causes beyond the control of
          the Issuing Lender, including without limitation any acts of
          governments.

               (v)  The obligations of the Lenders to make payments to the Agent
     for the account of the Issuing Lender with respect to Standby Letters of
     Credit shall be irrevocable and not subject to any qualification or
     exception whatsoever and shall be made in accordance with the terms and
     conditions of this Agreement under all circumstances, including, without
     limitation, any of the following circumstances:

                                                                              27
<PAGE>
 
               (A)  any lack of validity or enforceability of this Agreement or
          any of the other Loan Documents;

               (B)  the existence of any claim, setoff, defense or other right
          which the Borrowers may have at any time against a beneficiary named
          in a Standby Letter of Credit, any transferee of any Standby Letter of
          Credit (or any Person for whom any such transferee may be acting), the
          Agent, the Issuing Lender, any Lender, or any other Person, whether in
          connection with this Agreement, any Standby Letter of Credit, the
          transactions contemplated herein or any unrelated transactions;

               (C)  any draft, certificate or any other document presented under
          the Standby Letter of Credit shall prove to be forged, fraudulent,
          invalid or insufficient in any respect or any statement therein shall
          prove to be untrue or inaccurate in any respect;

               (D)  the surrender or impairment of any security for the
          performance or observance of any of the terms of any of the Loan
          Documents;

               (E)  the occurrence of any Event of Default or Potential Event of
          Default; or

               (F)  the termination of this Agreement or any Commitment.

          (e)  Standby Letter of Credit Drawings Constitute Revolving Loans.  
               ------------------------------------------------------------    
The Issuing Lender shall promptly notify the Agent, and the Agent shall promptly
notify each Lender, in each case by telecopy or telex or other customary form of
teletransmission, of any drawing under any Standby Letter of Credit (each
drawing, a "Drawing").  Each Drawing shall immediately be deemed to be and for
all purposes of this Agreement shall constitute a Revolving Loan hereunder in
the amount of such drawing.  Each Lender shall promptly and unconditionally
pay to the Agent for the account of the Issuing Lender an amount equal to such
Lender's Pro Rata Share of such Drawing in same day funds.  Such payment shall
be made to the Agent at the Agent Lending Office.  If the Agent delivers such
notice to such Lender prior to 2:00 P.M. (Eastern time) on any Business Day,
such Lender shall make its required payment on the same Business Day.  If and to
the extent such Lender shall not have made available to the Agent for the
account of the Issuing Lender such Lender's Pro Rata Share of such Drawing, such
Lender agrees to pay to the Agent for the account of the Issuing Lender,
promptly upon demand, such amount, together with interest thereon, for each day
from such date until the date such amount is paid to the Agent for the Account
of the Issuing Lender at

                                                                              28
<PAGE>
 
the Federal Funds Rate plus 100 basis points. The failure of any Lender to make
available to the Agent for the Account of the Issuing Lender its Pro Rata Share
of any Drawing shall not relieve any other Lender of its obligation hereunder to
make available to the Agent for the Account of the Issuing Lender its Pro Rata
Share of any Drawing on the date so required; provided, however, that no Lender
                                              --------  -------    
shall be responsible for the failure of any other Lender to make available to
the Agent for the account of the Issuing Lender such other Lender's Pro Rata
Share of such Drawing.

          Section 2.4  Swing Line Loan Subfacility.
                       --------------------------- 

          (a)  Swing Line Subfacility.  Subject to the terms and conditions
               ----------------------                                      
hereof, Crestar Bank, in its individual capacity (as such, the "Swing Line
Lender"), shall, in its sole and absolute discretion from and after the
Effective Date until one Business Day prior to the Maturity Date, make certain
revolving credit loans (each, a "Swing Line Loan" and, collectively, the "Swing
Line Loans") to the Borrowers; provided, however, that (i) the aggregate
                               --------  -------        -               
principal amount of all Swing Line Loans shall at no time exceed $10,000,000
(such amount, the "Swing Line Subfacility"), and (ii) the sum of the aggregate
                                                  --                          
amount of all Revolving Loans (whether bearing interest at the Base Rate or
Applicable LIBOR Rate) plus the aggregate amount of all Swing Line Loans plus
                       ----                                                  
the aggregate amount of all Standby Letters of Credit shall at no time exceed
the Aggregate Commitment.

          (b)  The Swing Line Note; Maturity.  The Swing Line Loans made by the
               -----------------------------                                   
Swing Line Lender pursuant hereto shall be evidenced by a separate Swing Line
Note.  The Swing Line Note shall be issued on or before the Effective Date and
shall bear interest for the period from the date of the initial funding of any
Swing Line Loan until paid in full on the unpaid principal amount thereof.  The
Swing Line Lender is hereby authorized to record in its books and records
(without making any notation on the Swing Line Note or any schedule thereto) the
amount and date of funding of each Swing Line Loan made by it, and the amount
and date of each payment or prepayment of any Swing Line Loan.  No failure to so
record nor any error in so recording shall affect the obligations of the
Borrowers to repay the actual outstanding principal amount of the Swing Line
Loans, with interest thereon, as provided in this Agreement.  The aggregate
principal amount of the Swing Line Loans shall be payable on the Maturity Date,
unless sooner accelerated pursuant to the terms of this Agreement.

          (c)  Swing Line Loan Borrowing Procedure.  Whenever the Borrowers
               -----------------------------------                         
desire to borrow Swing Line Loans under this Section 2.4, the Borrowers shall
deliver to the Swing Line Lender irrevocable written notice (each such notice, a
"Swing Line Borrowing Notice"), and the Swing Line Lender may, in its sole and
absolute discretion

                                                                              29
<PAGE>
 
and upon such other arrangements as shall be specifically agreed to by the Swing
Line Lender and the Borrowers, make a Swing Line Loan to the Borrowers on the
date (which shall be a Business Day), at the time and in the amount so agreed;
provided, however, that (i) the principal amount of any Swing Line Loan made
- --------  -------        -
hereunder shall not be less than $1,000,000.00 (and shall be in multiples of
$250,000.00) and (ii) an individual Swing Line Loan shall be offered by the

Swing Line Lender for a period of not less than 1 but not more than 29 days (any
such period, a "Swing Line Period").

          (d)  Interest on Swing Line Loans.  Subject to the provisions of 
               ----------------------------                                    
clause (e) of this Section 2.4, in the event that the Swing Line Lender shall
make any Swing Line Loan pursuant to Section 2.4 hereof, the aggregate principal
amount of Swing Line Loans outstanding from time to time shall bear interest at
a rate per annum equal to the Base Rate for the applicable Swing Line Period.

          (e)  Repayment of Swing Line Loans.  Each Swing Line Loan made by the
               -----------------------------                                   
Swing Line Lender hereunder shall be due and payable upon the expiration of the
Swing Line Period relating to such Swing Line Loan.  The Swing Line Lender may,
at any time and in its sole and absolute discretion, by written notice to the
Borrowers and the Agent (which shall promptly deliver a copy thereof to the
other Lenders), demand repayment of its Swing Line Loans then outstanding by way
of a Revolving Loan borrowing (a "Mandatory Borrowing"), in which case the
Borrower shall be deemed to have requested a Revolving Loan borrowing in the
amount of the then outstanding Swing Line Loans which shall bear interest at the
Base Rate; provided, however, that, in the following circumstances, any such
           --------  -------                                                
demand shall also be deemed to have been given one Business Day prior to each of
(i) the Maturity Date, (ii) the occurrence of any Event of Default described in
 -                      --                                         
clause (g), (h) or (i) of Section 7.1 hereof, (iii) upon acceleration of the
Obligations hereunder, whether on account of an Event of Default described in
clause (g), (h) or (i) of Section 7.1 or any other Event of Default, and (iv)
the exercise of remedies in accordance with the provisions of Section 7.1
hereof. Each Lender hereby irrevocably agrees to make such Revolving Loans
promptly upon any such request or deemed request on account of a Mandatory
Borrowing, in the amount (but in proportion to each Lender's Pro Rata Share) and
in the manner specified in the preceding sentence and on the same such date
notwithstanding that (A) the amount of the Mandatory Borrowing may not comply
- --------------------                                                  
with the minimum amount for borrowings of Revolving Loans otherwise required
hereunder, (B) whether any conditions specified in Section 4.2 are then
satisfied, (C) whether a Default or an Event of Default then exists, (D) failure
of any such request or deemed request for Revolving Loans to be made by the time
otherwise required in Section 2.2 hereof, (E) the date of such Mandatory
Borrowing, or (F) any reduction in the Revolving Loan Commitment or termination
of the Commitments relating thereto immediately prior to such Mandatory
Borrowing or

                                                                              30

contemporaneously therewith. In the event that any Mandatory Borrowing cannot
for any reason be made on the date otherwise required above (including, without
limitation, as a result of the commencement of a proceeding in bankruptcy with
respect to the Borrowers), then each Lender hereby agrees that it shall
forthwith purchase (as of the date the Mandatory Borrowing would otherwise have
occurred, but adjusted for any payments received from the Borrowers on or after
such date and prior to such purchase) from the Swing Line Lender such
participations in the then outstanding Swing Line Loans as shall be necessary to
cause each such Lender to share in such Swing Line Loans ratably based upon its
respective Pro Rata Share of the Revolving Loan Commitment (determined before
giving effect to any termination of the Revolving Loan Commitments pursuant to
the last paragraph of Section 7.1), provided that (x) all interest payable on
                                    --------         
the Swing Line Loans shall be for the account of the Swing Line Lender until the
date as of which the respective participation of each other Lender is purchased,
and (y) at the time any purchase of participations pursuant to this sentence is
actually made, the purchasing Lender shall be required to pay to the Swing Line
Lender interest on the principal amount of such participation purchased for each
day from and including the day upon which the Mandatory Borrowing would
otherwise have occurred to but excluding the date of payment for such
participation, at the rate equal to, if paid within two (2) Business Days of the
date of the Mandatory Borrowing, the Federal Funds Rate, and thereafter at a
rate equal to the Base Rate.

          (f)  Optional Prepayment of Swing Line Loans. Subject to the
               ---------------------------------------                 
provisions of this clause (f) and Section 3.9 hereof, the Borrowers may, at
their sole option, prepay the principal amount of the Swing Line Loans in whole
or in part (in an amount of $250,000 or more and in multiples of $250,000) at
any time and from time to time, without premium or penalty. In respect of each
Optional Prepayment of a Swing Line Loan proposed to be made by the Borrowers,
the right of the Borrowers to make such Optional Prepayment is subject to the
Agent's receipt from the Borrowers, no later than 12:00 P.M. on the Business Day
specified therein as the date on which such Optional Prepayment is to be made,
of a written notice (which shall be irrevocable) specifying (i) that the
                                                             -    
Borrowers desire to prepay such Swing Line Loan, (ii) the principal amount of
                                                  --

                               ---
which such Optional Prepayment will be made. Any Optional Prepayment of a Swing
Line Loan, which has not been converted to a Revolving Loan, made by the
Borrowers as permitted hereunder shall be paid to the Agent for the account of
the Swing Line Lender no later than 12:00 P.M. (Eastern Time) on the applicable
prepayment date.

pursuant to clause (b) of this Section 3.1, the aggregate principal amount of
the Revolving Loans outstanding from time to time shall bear interest at a rate
per annum equal to the Base Rate until the entire principal amount of the

the Revolving Loans resulting from a change in the Base Rate shall be effective
as of the opening of business on the day on which such change is effective.

          (b)  LIBOR Rate.  In the event the Borrowers shall effect a LIBOR
               ----------

LIBOR Rate as provided in Section 2.2(a) hereof, the aggregate principal amount
of the Revolving Loans that are the subject of such LIBOR Conversion or
Borrowing Notice, as the case may be, shall bear interest at a rate per annum
equal to the Applicable LIBOR Rate.  Any change in the Applicable LIBOR Rate
resulting from a change in the Consolidated Leverage Ratio shall be effective
five (5) Business Days after receipt of Borrowers' financial statements
reflecting such ratio; provided, however, that if such financial statements are

Agreement, any Regulatory Change:

          (a)  shall subject any Lender to any tax, duty or other charge with
respect to its obligation to make or maintain any Loan or its Commitment, or
shall change the basis of taxation of payments to such Lender of the principal
of or interest on the Loans or in respect of any other amounts due under this
Agreement in respect of its obligation to make any Loan or maintain its
Commitment (except for changes in the rate of tax on the overall net income of
such Lender); or

          (b)  shall impose, modify or deem applicable any reserve, assessment,
special deposit, capital adequacy, capital maintenance or similar requirement
against assets of, deposits with or for the account of, or credit extended by,
such Lender or shall impose on such Lender any other condition affecting (i) the
obligation of the Lender to make or maintain the Loans or its Commitment, or

cost to such Lender of making or maintaining any Loan or maintaining its
Commitment or to reduce the amount of any sum received or receivable by such
Lender under, or the rate of return attributable to, this Agreement or under the
Revolving Notes or the Swing Line Note, such Lender shall, within 30 days after
the effective date of such Regulatory Change, provide written notice to the
Borrowers of such Regulatory Change (it being agreed by the parties hereto that
if such notice is given after 30 days' of the effective date of such Regulatory
Change, the Borrowers shall be liable to the Lenders for the additional amounts
payable pursuant to this Section 3.2 only to the extent such additional amounts
accrue from and after the date of the giving of such notice), together with a
certificate describing in reasonable detail such increase or reduction, as the
case may be, then, within 30 days after delivery of such notice by such Lender
to the Borrowers if such Regulatory Change shall impose costs in excess of those
costs, or reduce the amount of any such sum or rate of return below the amount
or rate, applicable on the date of this Agreement, the Borrowers, shall pay to
the Agent for the account of such Lender for the account of such Lender such
additional amount or amounts as will compensate such Lender for such increase or
reduction. A certificate of such Lender setting forth the basis for the amount
of said increase or reduction, as the case may be, shall be conclusive in the
absence of manifest error.

Revolving Loans or Swing Line Loans, or of the Facility Fee, the Administrative
Fee, the L/C Fee or the L/C Fronting Fee, in each case within four (4) Business
Days after due (whether by demand, acceleration or otherwise), the Borrowers,

amount, payable from time to time on demand, from the expiration of such four
(4) Business Day period following the date such amount shall have become due to
the date of payment thereof, accruing on a daily basis, at a per annum rate (the
"Default Rate") equal to the sum of (a) the greater of the Base Rate and
Applicable LIBOR Rate determined on and, in the case of any continuing default,
from time to time after the date of such default plus (b) two percent (2%).

due date, the Borrowers hereby irrevocably instruct and authorize the Agent to
effect each payment of interest on the Loans as of the close of business on the
fourth Business Day following each Interest Payment Date, and of each payment of

Lender's Pro Rata Share of the Revolving Loan Commitment, a Facility Fee (the

outstanding amounts of Revolving Loans and Standby Letters of Credit.  The
Facility Fee shall be computed at a rate per annum equal to the Applicable
Facility Fee.  The Facility Fee shall be due and payable in arrears on the Fee
Payment Date to which such Facility Fee relates and on the Maturity Date, and
shall be calculated on the basis of a 360 day year and the actual days elapsed.

Borrowers shall not be entitled to any credit if any Lender as to which such fee
shall have been paid ceases to be a Lender hereunder for the entire year in

Agent resigns as such during any year as to which the Administrative Fee has
been paid by the Borrowers, the Agent shall reimburse the Borrowers for the
portion of such Administrative Fee related to the period for which the Agent
will not continue to serve as Agent, calculated on the basis of a 360-day year
and the actual days elapsed).

          Section 3.8    LIBOR Conversion
                         ----------------

          (a)  Conversion.  So long as no Event of Default or Potential Event of
               ----------                                                       
Default shall have occurred and be continuing, the Borrowers shall have the
right to convert all or part of the outstanding Revolving Loans bearing interest
at the then Base Rate to loans bearing interest at the then Applicable LIBOR
Rate (such conversion, a "LIBOR Conversion"); provided, however, that (i) the
                                              --------  -------              
LIBOR Period to which such LIBOR Conversion shall relate will not extend beyond
the Maturity Date and (ii) there shall not be outstanding at any one time more
than eight (8) LIBOR Loans.  In order to effect a LIBOR Conversion, the
Borrowers shall give the Agent irrevocable written notice (such notice, a "LIBOR
Conversion Notice") prior to 10:00 A.M. (Eastern time), at least three LIBOR
Business Days prior to the first day of the LIBOR Period to which such LIBOR
Conversion shall apply, stating that (i) the Borrowers wish to effect a LIBOR
Conversion, (ii) the aggregate principal amount of outstanding Revolving Loans
which the Borrowers wish to bear interest at the Applicable LIBOR Rate (it being
understood and agreed that no LIBOR Conversion shall be permitted in an amount
less than $3,000,000.00 and shall be in multiples of $500,000.00), (iii) the
applicable LIBOR Period being elected by the Borrowers (it being understood that
no change in LIBOR with respect to any LIBOR Loans may be effected during any
applicable LIBOR Period) and (iv) the Business Day on which the LIBOR Period is
to be effective.

          (b)  Notice of LIBOR to Borrowers.  In the event the Borrowers have
               ----------------------------                                  
requested a LIBOR Conversion, the Agent shall give written notice to the
Borrowers and the Lenders of LIBOR as promptly as reasonably possible after such
rate is determined.  The Agent's determination of LIBOR shall be conclusive in
the absence of manifest error.

          (c)  Successive Notice of LIBOR Conversion.  Subject to the provisions
               -------------------------------------                            
of clause (a) of this Section 3.8, the Borrowers may, by executing a LIBOR
Conversion Notice at least three LIBOR Business Days prior to the first day of
the LIBOR Period to which such LIBOR Conversion Notice shall apply, execute
successive LIBOR Conversions with respect to any Revolving Loan then outstanding
and bearing interest at the Base Rate together with any then outstanding LIBOR
Loans the LIBOR Period in respect of which is scheduled to expire on or before
the start of the LIBOR Period specified in such LIBOR Conversion Notice.  If,
with respect to any LIBOR Loans, the Agent shall not have received a LIBOR
Conversion Notice for the next immediately succeeding LIBOR Period which
complies with the provisions of clause (a) of this Section 3.8, such LIBOR 

                                                                              38

Loans shall, immediately upon the expiration of the then current LIBOR Period
and without any notice to the Borrowers, bear interest at the Base Rate in
accordance with the provisions of Section 3.1(a) of this Agreement.

          (d)  Market Disruption, etc.  In the event that the Agent (i) shall
               ----------------------                                        
have determined (which determination shall be conclusive and binding upon the
Borrowers) that by reason of circumstances affecting the London interbank market
either adequate or reasonable means do not exist for ascertaining LIBOR elected
by the Borrowers pursuant to the terms hereof or (ii) the Agent shall have
determined (which determination shall be conclusive and binding on the
Borrowers) that the applicable LIBOR will not adequately and fairly reflect the
cost to the Agent of maintaining or funding loans bearing interest based on such
LIBOR rate, with respect to any portion of the Revolving Loans that the
Borrowers have requested be made as a LIBOR Loan (each, an "Affected Advance"),
the Agent shall promptly notify the Borrowers (by telephone or otherwise, to be
promptly confirmed in writing), with a copy to the Lenders, of such
determination.  If the Agent shall give such notice, (x) any Affected Advances
shall be made as advances which shall bear interest at the Base Rate, and (y)
any outstanding LIBOR Loan shall, from and after the last day of the then
current LIBOR Period applicable thereto, bear interest at the Base Rate or, if
requested by Borrowers in accordance with Section 3.8(a) and the disruption
referred to in clause (i) or (ii) of this Section 3.8(d), as the case may be, is
no longer in existence, at the Applicable LIBOR Rate following conversion in
accordance with Section 3.8(a).  Until any notice under clause (i) or (ii) of
this Section 3.8(d) has been withdrawn by the Agent, no amounts outstanding or
to be advanced hereunder shall bear interest based upon LIBOR.

          Section 3.9    Breakage, etc.   In the event of the prepayment of any
                         --------------                                        
LIBOR Loan (whether by way of acceleration or otherwise or due to an Optional
Prepayment of any LIBOR Loan pursuant to Section 3.6(b) hereof), the Borrowers
shall pay to the Agent for the account of each Lender whose LIBOR Loan has been
so prepaid any loss or expense which such Lender may incur or sustain directly
as a result of such prepayment, including without limitation, an amount equal to
(a) an amount of interest which would have accrued on the amount so prepaid for
the period beginning on the date of such prepayment and ending on the last day
of the applicable LIBOR Period (such period, the "Breakage Period"), at the
Applicable LIBOR Rate minus (b) the amount of interest (as reasonably determined
by each affected Lender) which would have accrued to such Lender on such amount
by placing such amount on deposit for the Breakage Period with leading banks in
the London interbank market, in each case, as evidenced by a certificate
delivered to the Borrowers by each affected Lender, which certificate shall be
binding upon the Borrowers in the absence of manifest error.

          Section 8.1  Appointment of Agent.
                       -------------------- 

                                                                              62

          (a) Appointment Generally.  Each of the Lenders hereby designates and
              ---------------------                                            
appoints Crestar Bank as the Agent of such Lender under this Agreement and the
other Loan Documents, and each of the Lenders hereby irrevocably authorizes the
Agent to take such action on its behalf under the provisions of this Agreement
and the other Loan Documents and to exercise such powers as are set forth herein
and therein, together with such other powers as are incidental thereto.  The
Agent agrees to act as such on the express conditions contained in this Article
VIII.

          (b) Agent Acts for Lenders.  The provisions of this Article VIII are
              ----------------------                                          
solely for the benefit of the Agent and the Lenders and the Borrowers shall have
no right (including as third party beneficiary) to rely on or enforce any of the
provisions hereof.  In performing its functions and other duties under this
Agreement and the other Loan Documents, the Agent shall act solely as agent for
the Lenders and does not assume and shall not be deemed to have assumed any
obligation toward or relationship of agency or trust with or for the Borrowers
or any of their Affiliates.

          Section 8.2  Nature of Duties; Non-Reliance on Agent and other 
                       -------------------------------------------------
Lenders.
- ------- 

          (a) The Agent shall not have any duties or responsibilities except
those expressly set forth in this Agreement or in the other Loan Documents. The
duties of the Agent shall be mechanical and administrative in nature. The Agent
shall not have by reason of this Agreement or any other Loan Document a
fiduciary relationship in respect of any Lender and is not a trustee for the
Lenders. Nothing in this Agreement or any of the other Loan Documents, expressed
or implied, is intended to or shall be construed to impose upon the Agent any
obligations in respect of this Agreement or any of the other Loan Documents
except as expressly set forth herein and therein. If the Agent seeks the consent
or approval of the Lenders to the taking or refraining from taking of any action
hereunder, the Agent shall send notice thereof to each Lender. The Agent shall
promptly notify each Lender at any time the Required Lenders or all of the
Lenders, as the case may be, have instructed the Agent to act or refrain from
acting pursuant hereto. The Agent may execute any of its duties hereunder or
under any other Loan Document by or through agents or attorneys-in-fact and
shall be entitled to advice of counsel concerning all matters pertaining to such
duties. The Agent shall not be responsible for the negligence or misconduct of
any agents or attorneys-in-fact selected by it with reasonable care.

          (b) Each Lender expressly acknowledges that neither the Agent nor any
of its officers, directors, employees, agents, attorneys-in-fact or Affiliates
has made any representations or warranties to it and that no act by the Agent
or any Affiliate thereof hereinafter taken, including any review of the affairs
of the Borrowers or any 

                                                                              63
<PAGE>
 
Subsidiary thereof, shall be deemed to constitute any representation or warranty
by the Agent to any Lender. Each Lender represents to the Agent that it has,
independently and without reliance upon the Agent or any other Lender, and based
on such documents and information as it has deemed appropriate, made its own
appraisal of and investigation into the business, assets, operations, property,
financial and other conditions, prospects and creditworthiness of the Borrowers
and their Subsidiaries and made its own decision to make its Loans and issue or
participate in the issuance of Standby Letters of Credit hereunder and enter
into this Agreement and the other Loan Documents to which it is a party. Each
Lender covenants that it will, independently and without reliance upon the Agent
or any other Lender, and based on such documents and information as it shall
deem appropriate at the time, continue to make its own credit analysis,
appraisals and decisions in taking or not taking action under this Agreement or
any other Loan Document to which it is a party, and to make such investigations
as it deems necessary to inform itself as to the business, assets, operations,
property, financial and other conditions, prospects and creditworthiness of the
Borrowers and their Subsidiaries. Except for notices, reports and other
documents expressly required to be furnished to the Lenders by the Agent
hereunder, the Agent shall not have any duty or responsibility to provide any
Lender with any credit or other information concerning the business, operations,
assets, property, financial and other conditions, prospects or creditworthiness
of the Borrowers and their Subsidiaries which may come into the possession of
the Agent or any of its officers, directors, employees, agents, attorneys-in-
fact or Affiliates.

          Section 8.3  Rights, Exculpation, Etc.   Neither the Agent nor any
                       ------------------------                             
of its Affiliates nor any of their respective officers, directors, employees,
agents, attorneys or consultants shall be liable to any Lender for any action
taken or omitted by it or such Person hereunder or under any of the other Loan
Documents, or in connection herewith or therewith, except that (a) the Agent
shall be obligated on the terms set forth herein for performance of its express
obligations hereunder, and (b) neither the Agent nor any such other Person shall
have any liability hereunder or under any other Loan Document except to the
extent arising out of its own gross negligence or willful misconduct (as
determined by the final judgment of a court of competent jurisdiction). The
Agent shall not be liable for any apportionment or distribution of payments made
by it in good faith pursuant to the terms of this Agreement and if any such
apportionment or distribution is subsequently determined to have been made in
error the sole recourse of any Lender to whom payment was due, but not made,
shall be to recover from other Lenders any payment in excess of the amount to
which they are determined to have been entitled. The Agent shall not be
responsible to any Lender for any recitals, statements, representations or
warranties made by the Borrowers or Subsidiary thereof in this Agreement or in
any other Loan Document or in any other document, certificate report

                                                                              64

or financial statement delivered by the Borrowers or any Subsidiary thereof in
connection herewith or therewith or for the execution, effectiveness,
genuineness, validity, enforceability, collectibility, or sufficiency of this
Agreement or any of the other Loan Documents, or any of the transactions
contemplated thereby, or for the financial condition of the Borrowers or any of
their Subsidiaries. The Agent shall not be required to make any inquiry
concerning conditions of this Agreement or any of the Loan Documents or the
financial condition of the Borrowers or their Subsidiaries or the existence or
possible existence of any Potential Event of Default or Event of Default. The
Agent may at any time request instructions from the Lenders with respect to any
actions or approvals which by the terms of this Agreement or of any of the other
Loan Documents the Agent is permitted or required to take or to grant, and if
such instructions are promptly requested, the Agent shall be absolutely entitled
to refrain from taking any action or to withhold any approval and shall not
incur any liability whatsoever to any Person for refraining from any action or
withholding any approval under any of the Loan Documents until it shall have
received such instructions from the Required Lenders or, to the extent
specifically provided herein, all the Lenders or unless it shall first be
indemnified by the Lenders against any and all liability and expense which may
be incurred by it by reason of refraining to take any action or withholding any
approval. Without limiting the foregoing, no Lender shall have any right of
action whatsoever against the Agent as a result of the Agent acting or
refraining from acting under this Agreement or any of the other Loan Documents
in accordance with the instructions of the Required Lenders or, to the extent
specifically provided herein, all the Lenders, and such instructions shall be
binding upon all Lenders (including their successors and assigns).

          Section 8.4  Reliance; Notice of Default.
                       --------------------------- 

          (a) The Agent shall be entitled to rely upon any written notice,
statement, certificate, order, letter, cablegram, telegram, telecopy, telex or
teletype message, statement or other document or any telephone message believed
by it in good faith to be genuine and correct and to have been signed or made by
the proper Person, and with respect to all matters pertaining to this Agreement
or any of the other Loan Documents and its duties hereunder or thereunder, upon
advice of legal counsel (including counsel for the Borrowers), independent
public accountants and other experts selected by it with reasonable care.  The
Agent may deem and treat each Lender as the owner of its interests hereunder for
all purposes unless and until the Agent shall have received a duly executed
instrument of assignment as contemplated by Section 9.8(c) hereof and the other
conditions to assignment, to the extent applicable, shall have been satisfied.

                                                                              65
<PAGE>
 
          (b) The Agent shall not be deemed to have knowledge or notice of the
occurrence of any Event of Default or Potential Event of Default unless the
Agent has received notice from a Lender or the Borrowers referring to this
Agreement, describing such Event of Default or Potential Event of Default and
stating that such notice is a "notice of Event of Default" of "notice of
Potential Event of Default", as the case may be.  The Agent shall take such
action with respect to such Event of Default or Potential Event of Default as
shall be reasonably directed by the Required Lenders.

          Section 8.5  Indemnification.   To the extent that the Agent is not
                       ---------------                                       
reimbursed and indemnified by the Borrowers or the Borrowers fail upon demand by
the Agent to perform their obligations to reimburse or indemnify the Agent, the
Lenders will severally reimburse and indemnify the Agent for and against any and
all liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements of any kind or nature whatsoever which
may be imposed on, incurred by, or asserted against the Agent in any way
relating to or arising out of this Agreement or any of the other Loan Documents
or any action taken or omitted by the Agent under this Agreement or any of the
other Loan Documents, in proportion to each Lender's Pro Rata Share; provided,
                                                                     --------
that no Lender shall be liable for any portion of such liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements resulting from the Agent's gross negligence or willful misconduct
(as determined by the final judgment of a court of competent jurisdiction). The
obligations of the Lenders under this Section 8.5 shall survive the payment in
full of the Revolving Loans and the Swing Line Loans and the termination of this
Agreement.

          Section 8.6  The Agent Individually.   With respect to its Pro Rata
                       ----------------------                                
Share hereunder and the Revolving Loans, Swing Line Loans, if any, and Standby
Letters of Credit made by it, the Agent shall have and may exercise the same
rights and powers hereunder and is subject to the same obligations and
liabilities as and to the extent set forth herein for any other Lender.  The
term "Lenders" or "Required Lenders" or any similar terms shall, unless the
context clearly otherwise indicates, include the Agent in its individual
capacity as a Lender.  The Agent and its Affiliates may accept deposits from,
lend money to, and generally engage in any kind of banking, trust or other
business with the Borrowers as if it were not acting as Agent pursuant hereto.

          Section 8.7  Successor Agent; Resignation of Agent.
                       ------------------------------------- 

          (a) The Agent may resign from the performance of its functions and
duties hereunder at any time by giving at least twenty (20) days' prior written
notice to the Lenders and the Borrowers.  In the event that the Agent gives
notice of its desire to resign from the performance of its functions and duties
as Agent, any such resignation 

                                                                              66
<PAGE>
 
shall take effect only upon (i) the repayment of any portion of the fees
received by the Agent required by Section 3.7(c) and (ii) the acceptance by a
successor Agent of appointment pursuant to clauses (b) and (c) below.

          (b) The Required Lenders shall jointly appoint a successor Agent,
which shall be a Lender hereunder. A successor Agent that is not one of the
original Lenders under this Agreement shall be reasonably acceptable to the
Borrowers, such acceptance not to be unreasonably withheld, delayed or
conditioned. Unless the Borrowers object to the appointment of a successor Agent
within five (5) Business Days after receipt of notice thereof, the Borrowers
shall be conclusively presumed to have consented to the appointment of the
successor Agent.

          (c) If a successor Agent shall not have been so appointed within said
twenty (20) day period, the retiring Agent shall then appoint a successor Agent
who shall serve as Agent until such time, if any, as the Lenders appoint a
successor Agent as provided above, it being understood and agreed that any
successor Agent so appointed by the retiring Agent pursuant to this clause (c)
need not be, notwithstanding the provisions of clause (b) above, a Lender
hereunder so long as such successor Agent is a commercial bank organized under
the laws of the United States of America or of any State thereof or of the
District of Columbia and has a combined capital and surplus of at least
$1,000,000,000.00.

          (d) Upon the appointment of a successor Agent, the term "Agent" shall,
for all purposes of this Agreement and the other Loan Documents, thereafter
include such successor Agent, the retiring Agent shall be discharged from its
duties and obligations as Agent, as appropriate, under this Agreement and the
other Loan Documents and the successor Agent shall thereupon succeed to and
become vested with all the rights, powers, privileges and duties of the retiring
Agent, except that the retiring Agent shall reserve all rights as to obligations
accrued or due to it, in its capacity as such, at the time of such succession
and all rights (whenever arising) under Section 9.10 hereof.

          Section 8.8  Certain Matters Requiring the Consent of all Lenders.
                       ----------------------------------------------------   
Subject to the provisions of Section 8.9(b) hereof, the consent of all the
Lenders shall be required for taking any of the following required or permitted
actions hereunder:

          (a) any decrease or increase in any interest rate or margin applicable
to any Loan or in any fee payable hereunder, or change in the method of
computing the interest rate or margin applicable to any Loan or in any fee
payable hereunder;

          (b)  any change in the Maturity Date;

                                                                              67
<PAGE>
 
          (c) any increase in the Aggregate Commitment;

          (d) any increase or decrease in the Commitment of any Lender;

          (e) any change in the definition of Required Lenders;

          (f) any assignment or delegation of Borrowers' Obligations and rights
hereunder;

          (g) any change in the definition of Pro Rata Share;

          (h) any amendment, modification or waiver of this Section 8.8; and

          (i) any postponement of the date of payment of any principal, interest
or fees (other than the Administrative Fee, which may be postponed or waived at
the sole discretion of the Agent) due hereunder.

For the avoidance of doubt, all other actions, consents, waivers and amendments
permitted or required hereunder by the Lenders shall be by the Required Lenders
(unless such action, consent, waiver or amendment shall relate only to an
individual Lender, in which case such action may be taken by such Lender
individually).

          Section 8.9  Defaulting Lenders Vote Not Counted.   Whenever the
                       -----------------------------------                
"Required Lenders" or "all the Lenders" shall be required or permitted to take
any action pursuant to the provisions of any Loan Document, for so long as a
Lender shall be in default of its obligation to advance its Pro Rata Share of
any Loan or advance any other funds to the Agent or any other Lender as required
hereunder:

          (a) until the earlier of the cure of such default and the termination
of the Revolving Loan Commitment, the term Required Lenders for purposes of this
Agreement shall mean Lenders  (excluding all Lenders whose default shall have
not been cured) whose Pro Rata Shares represent more than sixty-six and two-
thirds percent (66K%) of the aggregate Pro Rata Shares of such Lenders; and

          (b) until the earlier of the cure of such default and the termination
of the Revolving Loan Commitment, the term "all the Lenders" for purposes of
this Agreement shall mean Lenders (excluding all Lenders whose default shall
have not been cured) whose Pro Rata Shares represent one hundred percent (100%)
of the aggregate Pro Rata Shares of such Lenders.

                                                                              68

          Section 9.1  Amendments and Waivers; Cumulative Remedies.   No delay
                       -------------------------------------------            
or failure of any Lender or the Agent or the holder of any the Revolving Notes
or the Swing Line Note in exercising any right, power or privilege hereunder or
under any other Loan Document shall affect such right, power or privilege; nor
shall any single or partial exercise thereof or any abandonment or
discontinuance of steps to enforce such a right, power or privilege preclude any
further exercise thereof or of any other right, power or privilege. The rights
and remedies of any Lender or the Agent or any other holder of the Revolving
Notes or the Swing Line Note are cumulative and not exclusive of any rights or
remedies which any of them would otherwise have. Neither this Agreement or any
other Loan Document, nor any term, condition, representation, warranty, covenant
or agreement hereof or thereof, may be changed, waived, discharged or terminated
orally but only by an instrument in writing executed by the party against whom
such change, waiver, discharge or termination is sought. Any waiver, permit,
consent or approval of any kind or character (whether involving a breach,
default, provision, condition or term hereof or otherwise) on the part of any
Lender or the Agent or any other holder of any Note, or of the Borrowers under
this Agreement, or under any other Loan Document shall be effective only in the
specific instance and for the purpose for which given and only to the extent set
forth specifically in writing. No notice or demand given hereunder shall entitle
the recipient thereof to any other or further notice or demand in similar or
other circumstances.

          Section 9.2  Survival of Representations and Warranties.   All
                       ------------------------------------------       
representations, warranties, covenants and agreements of the Borrowers contained
herein or made in writing in connection herewith shall survive the execution and
delivery of this Agreement, the making of Loans hereunder and the  issuance of
the Notes.

Governmental Authority, (b) any change in the existing laws, rules and
regulations of any Governmental Authority, (c) the issuance of any order or
decree by any Governmental Authority, (d) any change in the interpretation or
administration of any applicable law, rule, regulation, order or decree by any
Governmental Authority (including any central bank or similar agency) charged

Lender to maintain the Revolving Loans or the Swing Line Loans, such Lender
shall so notify the Borrowers and the Agent and such Lender, by giving the
Borrowers at least one hundred twenty (120) Business Days' prior written notice,
may require the Borrowers to prepay the aggregate principal amount of, and all
accrued and unpaid Facility Fee and all other fees and all accrued and unpaid
interest on, the Revolving Loans and the Swing Line Loans, as the case may be
(together with any other amounts that may become payable hereunder as a result
thereof, including all amounts pursuant to Section 9.10 of this Agreement), on a
Business Day (the "Prepayment Date") specified in such notice. If after the date
of this Agreement and prior to the initial Funding Date it shall become unlawful
for any Lender to make any Revolving Loans or Swing Line Loans hereunder or to
maintain its Commitment, this Agreement shall terminate forthwith with respect
to such Lender and neither such Lender nor the Borrowers shall have any further
rights or obligations under this Agreement, provided, however, that the
Borrowers, in the event of any termination pursuant to this second sentence of
Section 9.3, shall pay to such Lender the amount of all accrued and unpaid fees,
if any, together with all amounts then due pursuant to Section 9.10 hereof. If
it shall become unlawful for any such Lender to make any Revolving Loans or
Swing Line Loans as provided in this Section 9.3, the Revolving Loan Commitment
shall automatically be deemed to be decreased in the amount of such Lender's Pro
Rata Share, and the Commitment of each such other Lender shall be adjusted
accordingly.

including any reduction or deduction for any set-off, recoupment, counterclaim
(whether sounding in tort, contract or otherwise) or tax.

          Section 9.5  Stamp Taxes.   The Borrowers agree to pay, and to save

transfer, documentary or similar taxes, assessments or charges (herein "Stamp
Taxes"), and any penalties or interest (excluding any penalties or interest
resulting from the willful misconduct or gross negligence of any Lender or the
Agent) with respect thereto, which may be assessed, levied, collected or imposed
by or upon such Lender, or otherwise become payable by such Lender, in

          Section 9.8  Successors and Assigns; Participations; Assignments.
                       --------------------------------------------------- 

          (a) Successors and Assigns.  This Agreement shall be binding upon and
              ----------------------                                           
inure to the benefit of and be enforceable by the respective permitted
successors and assigns of the parties hereto, provided that the Borrowers may
                                              --------                       
not assign or transfer any of its interest hereunder without the prior written
consent of the Lenders and the Agent.

          (b) Participations.  Any Lender may sell participation in all or any
              --------------                                                  
part of the Revolving Loans made by it or its Commitment or any other interest
herein or in its Revolving Note or in any other document delivered or instrument
delivered in connection herewith to another bank or other entity.  In the case
of such participation by a Lender, (i) the participant shall not have any rights
under this Agreement or the applicable Revolving Note or any other document or
instrument delivered in connection herewith (the participant's rights against
such Lender in respect of such participation to be those set forth in the
agreement executed by such Lender in favor of the participant relating thereto),
(ii) all amounts payable by the Borrowers shall be determined as if such
Lender had not sold such participation and (iii) the Borrowers shall continue to
deal directly with such Lender with respect to the transactions contemplated
hereby.

          (c) Assignments.  Each Lender may assign any of its rights or
              -----------                                              
interests under the Loan Documents to one or more financial institutions,
provided that:
- --------      

              (i)   each such assignment shall be in an amount not less than
     $10,000,000.00 (or such lesser amount if, after giving effect to such
     assignment 

                                                                              72
<PAGE>
 
     and all other assignments by such Lender occurring substantially
     simultaneously therewith, such assigning Lender shall hold no Commitment or
     any Revolving Loan);

              (ii)  each such assignment by a Lender of its Commitment or
     Revolving Loans shall be made in such manner so that the same portion of
     such Lender's Commitment, Revolving Loans, Revolving Note and obligations
     in respect of any Standby Letter of Credit is assigned to the respective
     assignee Lender;

              (iii) the assigning Lender shall pay to the Agent a one-time fee
     in the amount of $3,000.00; and

              (iv)  the Parent Borrower and the Agent shall have consented to
     such Assignment, which consent shall not be unreasonably withheld or
     delayed; provided that no consent of the Parent Borrower shall be required
              --------                                                         
     for assignments (x) to a Lender or an Affiliate of a Lender or (y) during
     the continuance of an Event of Default.

Upon execution and delivery by the assignee to the Borrowers and the Agent of an
instrument in writing pursuant to which such assignee agrees to be a "Lender"
hereunder (if not already a Lender) having the Commitment and Revolving Loans
specified in such assignment, and upon the consent of the Parent Borrower or the
Agent to the extent required above, the assignee shall have, to the extent of
such assignment, the rights, benefits and obligations of a Lender hereunder
holding the Commitment, Revolving Loans (or portions thereof) and Standby
Letters of Credit or deemed participations therein, as applicable, assigned to
it pursuant to such assignment (in addition to the Commitment, Revolving Loans
(or portions thereof) and Standby Letters of Credit or deemed participations
therein, as applicable, theretofore held by such assignee), and the assigning
Lender shall, to the extent of such assignment, be relieved from its Commitment
(or portion thereof) and other obligations hereunder so assigned.

          Section 9.9   Affirmative Rate of Interest Permitted by Law.   Nothing
                        ---------------------------------------------           
in this Agreement or in any Note shall require the Borrowers to pay interest to
the Agent for the account of the Lenders at a rate exceeding the maximum rate
permitted by applicable law to be charged or received by the Lenders, it being
understood that this Section 9.9 is not intended to make the criminal laws of
any jurisdiction applicable in circumstances in which they would not otherwise
apply.  If the rate of interest specified herein, in any Revolving Note or in
the Swing Line Note would otherwise exceed the maximum rate so permitted to be
charged or received with respect to any amounts 

                                                                              73

outstanding hereunder or under such Revolving Note or the Swing Line Note, the
rate of interest required to be paid to the Agent for the account of the Lenders
shall be automatically reduced to such maximum rate.

          Section 9.10  Costs and Expenses; Indemnification.
                        ----------------------------------- 

          (a) Without regard to whether the Effective Date shall have come into
existence or whether any Revolving Loan or Swing Line Loan or Standby Letter of
Credit shall have been made or issued hereunder, the Borrowers shall pay to each
Lender and the Agent, as the case may be, and reimburse each Lender and the
Agent for, as the case may be, and save each Lender and the Agent, as the case
may be, harmless from and indemnify each Lender and the Agent, as the case may
be, against losses from:  (i) all out-of-pocket costs and expenses of the Agent
and the Lenders (including such costs and expenses incurred by the Agent on
behalf of the Lenders) in connection with the preparation, execution, delivery,
waiver, modification and amendment of this Agreement and any other Loan Document
(to the extent applicable) and any other document or instrument delivered in
connection with the transactions contemplated hereby, including, without
limitation, the reasonable fees and expenses of counsel for the Agent with
respect thereto, and (ii) all reasonable out-of-pocket costs and expenses, if
any (including, without limitation, reasonable counsel fees and expenses), of
the Agent in such capacity (including such costs and expenses incurred by the
Agent on behalf of the Lenders) in connection with the enforcement (whether
through negotiations, legal proceedings or otherwise) of this Agreement and any
other Loan Document and any other document or instrument delivered in connection
with the transactions contemplated hereby, including, for the avoidance of doubt
and without limitation, reasonable counsel fees and expenses in connection with
the enforcement of rights under this Section 9.10(a); provided, that,
                                                      --------       
notwithstanding the foregoing, the Borrowers shall not be obligated to pay costs
and expenses referred to in this Section 9.10(a) to the extent that such costs
and expenses directly result from the gross negligence or willful misconduct of
a Lender or the Agent.

          (b) The Borrowers shall jointly and severally indemnify and hold
harmless each Lender, the Agent and their respective affiliates, officers,
directors, employees, agents and advisors (each, an "Indemnified Person") from
and against, and pay and reimburse each Indemnified Person for, any and all
claims, damages, losses, liabilities and expenses (including, without
limitation, reasonable fees and disbursements of counsel) which may be incurred
by or asserted or awarded against any Indemnified Person in each case arising
out of or in connection with or by reason of, or in connection with the
preparation for a defense of, any investigation, litigation or proceeding
arising out of, related to or in connection with this Agreement, the 

                                                                              74
<PAGE>
 
Revolving Notes, the Swing Line Note and any other document or instrument
delivered in connection with the transactions contemplated hereby, whether or
not an Indemnified Person is a party hereto or thereto and whether or not the
Effective Date shall have come into existence or any Revolving Loan or Swing
Line Loan or Standby Letter of Credit has been made or issued under this
Agreement; provided, however, that the Borrowers shall have no obligation to
           --------  -------
indemnify or hold harmless any Indemnified Person for liability or expenses to
the extent arising out of such Indemnified Person's gross negligence or willful
misconduct.

          (c) All amounts payable by the Borrowers under this Section 9.10 shall
be immediately due upon written request by a Lender or Agent, as the case may
be, for the payment thereof.  The obligations of the Borrowers under this
Section 9.10 shall survive the payment of the Revolving Notes and the Swing Line
Note.

          Section 9.11  Set-Off; Suspension of Payment and Performance.   Each
                        ----------------------------------------------        
Lender and the Agent is hereby authorized by the Borrowers, at any time and from
time to time, without notice (a) during any Event of Default, to set off
against, and to appropriate and apply to the payment of, the liabilities of the
Borrowers then due under this Agreement and any other Loan Document any and all
liabilities owing by any Lender or the Agent or any of their Affiliates to the
Borrowers (whether payable in Dollars or any other currency, whether matured or
unmatured and, in the case of liabilities that are deposits (including, without
limitation, any funds from time to time on deposit in the Borrowers' Account or
other account maintained with any Lender or the Agent Lender, whether general or
special, time or demand and however evidenced and whether maintained at a branch
or office located within or without the United States), and (b) during any Event
of Default, to suspend the payment and performance of such liabilities owing by
such Person or its Affiliates and, in the case of liabilities that are deposits,
to return as unpaid for insufficient funds any and all checks and other items
drawn against such deposits.

          Section 9.12  Sharing of Collections, Proceeds and Set-Offs;
                        ----------------------------------------------
Application of Payments.
- ----------------------- 

          (a) If any Lender, by exercising any right of set-off, counterclaim,
foreclosure or otherwise, receives payment of principal or interest or other
amount due on any Loan or Standby Letter of Credit which is greater than the Pro
Rata Share of such Lender, the Lender receiving such proportionately greater
payment shall purchase such participations in the Loans and Standby Letter of
Credit reimbursement obligations held by the other Lenders, and such other
adjustments shall be made as may be required, so that all such payments shall be
shared by the Lenders on the basis of their 

                                                                              75
<PAGE>
 
respective Pro Rata Shares; provided that if all or any portion of such
                            --------
proportionately greater payment of such indebtedness is thereafter recovered
from, or must otherwise be restored by, such purchasing Lender, the purchase
shall be rescinded and the purchase price restored to the extent of such
recovery, but without interest being paid by such purchasing Lender. Borrowers
agree, to the fullest extent they may effectively do so under applicable law,
that any holder of a participation in a Loan or reimbursement obligation,
whether or not acquired pursuant to the foregoing arrangements, may exercise
rights of set-off or counterclaim and other rights with respect to such
participation as fully as if such holder of a participation were a direct
creditor of Borrowers in the amount of such participation. If under any
applicable bankruptcy, insolvency or other similar law, any Lender receives a
secured claim in lieu of a set-off to which this Section would apply, such
Lender shall, to the extent practicable, exercise its rights in respect of such
secured claim in a manner consistent with the rights of the Lenders entitled
under this Section to share in the benefits of any recovery on such secured
claim.

          (b) If an Event of Default or a Potential Event of Default shall have
occurred and be continuing, the Agent and each Lender and Borrowers agree that
all payments on account of the Loans and Standby Letters of Credit shall be
applied by the Agent and the Lenders as follows:

              (i)   First, to the Agent for any fees then due and payable to the
     Agent under this Agreement until such fees are paid in full;

              (ii)  Second, to the Agent for any fees, costs or expenses
     (including expenses described in Section 9.10) incurred by the Agent under
     any of the Loan Documents or this Agreement, then due and payable and not
     reimbursed by Borrowers or the Lenders until such fees, costs and expenses
     are paid in full;

              (iii) Third, to the Lenders for their Pro Rata Shares of the
     Facility Fee then due and payable under this Agreement until such fee is
     paid in full;

              (iv)  Fourth, to the Lenders for their respective shares of all
     costs, expenses and fees then due and payable from Borrowers until such
     costs, expenses and fees are paid in full;

              (v)   Fifth, to the Lenders for their Pro Rata Shares of all
     interest then due and payable from Borrowers until such interest is paid in
     full; and

                                                                              76
<PAGE>
 
              (vi)  Sixth, to the Lenders for their Pro Rata Shares of the
     principal amount of the Loans and reimbursement obligations with respect to
     Standby Letters of Credit then due and payable from Borrowers until such
     principal is paid in full, which percentage shares shall be calculated by
     determining each Lender's Pro Rata Share.

          Section 9.13  Lenders' Obligations Several; Independent Nature of
                        ---------------------------------------------------
Lenders' Rights.   The obligation of each Lender hereunder is several and not
- ---------------                                                                
joint, and no Lender shall be the agent of any other (except to the extent the
Agent is authorized to act as such hereunder).  No Lender shall be responsible
for the obligation or commitment of any other Lender hereunder.  In the event
that any Lender at any time should fail to make a Loan as herein provided, the
other Lenders, or any of them as may then be agreed upon, at their sole option,
may make the Loan that was to have been made by the Lender so failing to make
such Loan. Nothing contained in any Loan Document and no action taken by Agent
or any Lender pursuant hereto or thereto shall be deemed to constitute Lenders
to be a partnership, an association, a joint venture or any other kind of
entity. The amounts payable at any time hereunder to each Lender shall be a
separate and independent debt.

          Section 9.14  Judicial Proceedings; Waiver of Jury Trial.   Any
                        ------------------------------------------       
judicial proceeding brought against the Borrowers with respect to any Credit
Agreement Related Claim may be brought in any court of competent jurisdiction in
the Commonwealth of Virginia, and, by execution and delivery of this Agreement,
the Borrowers (a) accepts, generally and unconditionally, the nonexclusive
jurisdiction of such courts and any related appellate court and irrevocably
agrees to be bound by any judgment rendered thereby in connection with any
Credit Agreement Related Claim and (b) irrevocably waives any objection it may
now or hereafter have as to the venue of any such proceeding brought in such a
court or that such a court is an inconvenient forum.  The Borrowers hereby
waives personal service of process and consents that service of process upon it
may be made by certified or registered mail, return receipt requested, at its
address specified or determined in accordance with the provisions of Section 9.6
of this Agreement, and service so made shall be deemed completed on the earlier
of (i) the receipt thereof and (ii) the fifth (5th) Business Day after such
service is deposited in the mail. Nothing herein shall affect the right of any
Lender, the Agent or any other Indemnified Person to serve process in any other
manner permitted by law or shall limit the right of any Lender, the Agent or any
other Indemnified Person to bring proceedings against the Borrowers in the
courts of any other jurisdiction. Any judicial proceeding by the Borrowers
against any Lender or the Agent involving any Credit Agreement Related Claim
shall be brought only in a court located in the Commonwealth of Virginia. THE
BORROWERS AND THE LENDERS AND THE AGENT HEREBY WAIVE 

                                                                              77

promptly and duly execute and deliver to a Lender or the Agent, as the case may
be, and to such other persons as such Lender or the Agent shall designate, such
further instruments and shall take such further action as may be required by law
or as such Lender or the Agent may from time to time request in order more
effectively to carry out and accomplish the intent and purpose of this Agreement
and the other Loan Documents and to establish and protect the rights and
remedies created or intended to be created in favor of the Lender hereunder or
under any other Loan Document.

          Section 9.17  No Fiduciary Relationship.   The Borrowers acknowledges
                        -------------------------                              
that no provision of this Agreement or in any of the other Loan Documents, and

                        ------------

invalid or unenforceable in whole or in part in any jurisdiction, then such
clause or provision shall, as to such jurisdiction, be ineffective to the extent
of such invalidity or unenforceability without in any manner affecting the
validity or enforceability of such clause or provision in any other jurisdiction
or the remaining provisions hereof in any jurisdiction.

number of counterparts and by different parties hereto on separate counterparts,
each complete set of which, when so executed and delivered by all parties, shall
be an original, but all such counterparts shall together constitute but one and
the same instrument.

No Option that is intended to be an incentive stock option shall be invalid for

                                 --------------

     The Plan shall be administered by the Administrator.  The Administrator
shall have authority to grant Stock Awards, Performance Shares, Options and SARs
upon such terms (not inconsistent with the provisions of this Plan), as the
Administrator may consider appropriate.  Such terms may include conditions (in
addition to those contained in this Plan) on the exercisability of all or any
part of an Option or SAR or on the transferability or forfeitability of a Stock
Award or an award of Performance Shares, including by way of example and not of
limitation, conditions on which

<PAGE>
 
Participants may defer receipt of benefits under the Plan, requirements that the
Participant complete a specified period of employment with the Company or a
Related Entity, requirements that the Company achieve a specified level of
financial performance or that the Company achieve a specified level of financial
return.  Notwithstanding any such conditions, the Administrator may, in its
discretion, accelerate the time at which any Option or SAR may be exercised, or
the time at which a Stock Award may become transferable or nonforfeitable or
both, or the time at which an award of Performance Shares may be settled or may
waive any of the conditions referred to above.  In addition, the Administrator
shall have complete authority to interpret all provisions of this Plan; to
prescribe the form of Agreements; to adopt, amend, and rescind rules and
regulations pertaining to the administration of the Plan; and to make all other
determinations necessary or advisable for the administration of this Plan.  The
express grant in the Plan of any specific power to the Administrator shall not
be construed as limiting any power or authority of the Administrator.  Any
decision made, or action taken, by the Administrator in connection with the
administration of this Plan shall be final and conclusive.  Neither the
Administrator nor any member of the Committee shall be liable for any act done
in good faith with respect to this Plan or any Agreement, Option, SAR, Stock
Award or award of Performance Shares.  All expenses of administering this Plan
shall be borne by the Company, a Related Entity or a combination thereof.

     The Committee, in its discretion, may delegate to one or more officers of
the Company all or part of the Committee's authority and duties with respect to
grants and awards to individuals who are not subject to the reporting and other
provisions of Section 16 of the Exchange Act.  The Committee may revoke or amend
the terms of a delegation at any time but such action shall not invalidate any
prior actions of the Committee's delegate or delegates that were consistent with
the terms of the Plan.



                                   ARTICLE IV

     Any employee of the Company or a Related Entity (including a corporation
that becomes a Related Entity after the adoption of this Plan), is eligible to
participate in this Plan if the Administrator, in its sole discretion,
determines that such person has contributed or can be expected to contribute to
the profits or growth of the Company or a Related Entity.  Directors of the
Company who are employees of the Company or a Related Entity may be selected to

of Common Stock allocated to the Option or portion thereof may be reallocated to
other Options, SARs, Performance Shares and Stock Awards to be granted under
this Plan. If an SAR is terminated, in whole or in part, for any reason other
than its exercise or the exercise of a related Option, the number of shares of
Common Stock allocated to the SAR or portion thereof may be reallocated to other
Options, SARs, Performance Shares and Stock Awards to be granted under this
Plan. If an award of Performance Shares is terminated, in whole or in part, the
number of shares of Common Stock allocated to the Performance Shares or portion
thereof may be reallocated to other options, SARs, Performance Shares and Stock
Awards to be granted under this Plan. If a Stock Award is forfeited, in whole or

Stock Award or portion thereof may be reallocated to other Options, SARs,
Performance Shares and Stock Awards to be granted under this Plan.

Option shall be determined by the Administrator on the date of grant, but shall
not be less than the Fair Market Value on the date the Option is granted.

6.03.      MAXIMUM OPTION PERIOD
           ---------------------

           The maximum period in which an Option may be exercised shall be ten
years from the date such Option was granted. The terms of any Option may provide
that it has a term that is less than such maximum period.

6.04.      NONTRANSFERABILITY
           ------------------

           Except as provided in Section 6.05, each Option granted under this
Plan shall be nontransferable except by will or by the laws of descent and
distribution. In the event of any transfer of an Option (by the Participant or
his transferee), the Option and any Corresponding SAR that relates to such
Option must be transferred to the same person or persons or entity or entities.
Except as provided in Section 6.05, during the lifetime of the Participant to
whom the Option is granted, the Option may be exercised only by the Participant.
No right or interest of a Participant in any Option shall be liable for, or
subject to, any lien, obligation, or liability of such Participant.

6.05.      TRANSFERABLE OPTIONS
           --------------------

           Section 6.04 to the contrary notwithstanding, if the Agreement
provides, an Option that is not an incentive stock option may be transferred by
a Participant to the Participant's children, grandchildren, spouse, one or more
trusts for the benefit of such family members or a partnership in which such
family members are the only partners, on such terms and conditions as may be
permitted under Securities Exchange Commission Rule 16b-3 as in effect from time
to time. The holder of an Option transferred pursuant to this section shall be
bound by the same terms and conditions that governed the Option during the
period that it was held by the Participant; provided, however, that such
transferee may not transfer the Option

                                       9
<PAGE>
 
except by will or the laws of descent and distribution.  In the event of any
transfer of an Option (by the Participant or his transferee), the Option and any
Corresponding SAR that relates to such Option must be transferred to the same
person or persons or entity or entities.

6.06.      EMPLOYEE STATUS
           ---------------

           For purposes of determining the applicability of Section 422 of the
Code (relating to incentive stock options), or in the event that the terms of
any Option provide that it may be exercised only during employment or within a
specified period of time after termination of employment, the Administrator may
decide to what extent leaves of absence for governmental or military service,
illness, temporary disability, or other reasons shall not be deemed
interruptions of continuous employment.

6.07.      EXERCISE
           --------

           Subject to the provisions of this Plan and the applicable Agreement,
an Option may be exercised in whole at any time or in part from time to time at
such times and in compliance with such requirements as the Administrator shall
determine; provided, however, that incentive stock options (granted under the
Plan and all plans of the Company and its Related Entities) may not be first
exercisable in a calendar year for stock having a Fair Market Value (determined
as of the date an Option is granted) exceeding the limit prescribed by Code
section 422(d). An Option granted under this Plan may be exercised with respect
to any number of whole shares less than the full number for which the Option
could be exercised. A partial exercise of an Option shall not affect the right
to exercise the Option from time to time in accordance with this Plan and the
applicable Agreement with respect to the remaining shares subject to the Option.
The exercise of an Option shall result in the termination of any Corresponding
SAR to the extent of the number of shares with respect to which the Option is
exercised.

6.08.      PAYMENT
           -------

           Unless otherwise provided by the Agreement, payment of the Option
price shall be made in cash or a cash equivalent acceptable to the
Administrator. Subject to rules established by the Administrator, payment of all
or part of the Option price may be made with shares of Common Stock which have
been owned by the Participant for at least six months and which have not been
used for another exercise during the prior six months. If Common Stock is used
to pay all or part of the Option price, the sum of the cash and cash equivalent
and the Fair Market Value (determined as of the day preceding the date of
exercise) of such shares must not be less than the Option price of the shares
for which the Option is being exercised.

6.09.      CHANGE IN CONTROL
           -----------------

           Section 6.07 to the contrary notwithstanding, each outstanding Option
shall be fully exercisable (in whole or in part at the discretion of the holder)
on and after a Control Change Date and during the period (i) beginning on the
first day after the commencement of a tender offer or exchange offer for shares
of Common Stock (other than an offer made by the Company); provided that shares
are acquired pursuant to such offer and (ii) ending on the thirtieth day
following the expiration of such offer.

6.10.      SHAREHOLDER RIGHTS
           ------------------

           No Participant shall have any rights as a shareholder with respect to
shares subject to his Option until the date of exercise of such Option.

6.11.      DISPOSITION OF STOCK
           --------------------

           A Participant shall notify the Company of any sale or other
disposition of Common Stock acquired pursuant to an Option that was an incentive
stock option if such sale or disposition occurs (i) within two years of the
grant of an Option or (ii) within one year of the issuance of the Common Stock
to the Participant. Such notice shall be in writing and directed to the
Secretary of the Company.

                                     SARS
                                     ----
7.01.      AWARD
           -----

           In accordance with the provisions of Article IV, the Administrator
will designate each individual to whom SARs are to be granted and will specify
the number of shares covered by each such award. In addition, no Participant may
be granted Corresponding SARs (under all incentive stock option plans of the
Company and its Affiliates) that are related to incentive stock options which
are first exercisable in any calendar year for stock having an aggregate Fair
Market Value (determined as of the date the related Option is granted) that
exceeds the limit prescribed by Code section 422(d).

7.02.      MAXIMUM SAR PERIOD
           ------------------

           The maximum period in which an SAR may be exercised shall be ten
years from the date such SAR was granted. The terms of any SAR may provide that
it has a term that is less than such maximum period.

                                       11
<PAGE>
 
7.03.      NONTRANSFERABILITY
           ------------------

           Except as provided in Section 7.04, each SAR granted under this Plan
shall be nontransferable except by will or by the laws of descent and
distribution. In the event of any such transfer, a Corresponding SAR and the
related Option must be transferred to the same person or persons or entity or
entities. Except as provided in Section 7.04, during the lifetime of the
Participant to whom the SAR is granted, the SAR may be exercised only by the
Participant. No right or interest of a Participant in any SAR shall be liable
for, or subject to, any lien, obligation, or liability of such Participant.

7.04.      TRANSFERABLE SARS
           -----------------

           Section 7.03 to the contrary notwithstanding, if the Agreement
provides, an SAR, other than a Corresponding SAR that is related to an incentive
stock option, may be transferred by a Participant to the Participant's children,
grandchildren, spouse, one or more trusts for the benefit of such family members
or a partnership in which such family members are the only partners, on such
terms and conditions as may be permitted under Securities Exchange Commission
Rule 16b-3 as in effect from time to time. The holder of an SAR transferred
pursuant to this section shall be bound by the same terms and conditions that
governed the SAR during the period that it was held by the Participant;
provided, however, that such transferee may not transfer the SAR except by will
or the laws of descent and distribution. In the event of any transfer of a
Corresponding SAR (by the Participant or his transferee), the Corresponding SAR
and the related Option must be transferred to the same person or person or
entity or entities.

7.05.      EXERCISE
           --------

           Subject to the provisions of this Plan and the applicable Agreement,
an SAR may be exercised in whole at any time or in part from time to time at
such times and in compliance with such requirements as the Administrator shall
determine; provided, however, that a Corresponding SAR that is related to an
incentive stock option may be exercised only to the extent that the related
Option is exercisable and only when the Fair Market Value exceeds the option
price of the related Option. An SAR granted under this Plan may be exercised
with respect to any number of whole shares less than the full number for which
the SAR could be exercised. A partial exercise of an SAR shall not affect the
right to exercise the SAR from time to time in accordance with this Plan and the
applicable Agreement with respect to the remaining shares subject to the SAR.
The exercise of a Corresponding SAR shall result in the termination of the
related Option to the extent of the number of shares with respect to which the
SAR is exercised.

7.06.      CHANGE IN CONTROL
           -----------------

           Section 7.05 to the contrary notwithstanding, each outstanding SAR
shall be fully exercisable (in whole or in part at the discretion of the holder)
on and after a Control Change Date and during the period (i) beginning on the
first day after the commencement of a tender offer or exchange offer for shares
of Common Stock (other than one made by the Company); provided that shares are
acquired pursuant to such offer and (ii) ending on the thirtieth day following
the expiration of such offer.

7.07.      EMPLOYEE STATUS
           ---------------

           If the terms of any SAR provide that it may be exercised only during
employment or within a specified period of time after termination of employment,
the Administrator may decide to what extent leaves of absence for governmental
or military service, illness, temporary disability or other reasons shall not be
deemed interruptions of continuous employment.

7.08.      SETTLEMENT
           ----------

           At the Administrator's discretion, the amount payable as a result of
the exercise of an SAR may be settled in cash, Common Stock, or a combination of
cash and Common Stock. No fractional share will be deliverable upon the exercise
of an SAR but a cash payment will be made in lieu thereof.

7.09.      SHAREHOLDER RIGHTS
           ------------------

           No Participant shall, as a result of receiving an SAR, have any
rights as a shareholder of the Company until the date that the SAR is exercised
and then only to the extent that the SAR is settled by the issuance of Common
Stock.



                                 ARTICLE VIII

                                 STOCK AWARDS
                                 ------------
8.01.      AWARD
           -----

           In accordance with the provisions of Article IV, the Administrator
will designate each individual to whom a Stock Award is to be made and will
specify the number of shares of Common Stock covered by each such award.

8.02.      VESTING
           -------

           The Administrator, on the date of the award, may prescribe that a
Participant's rights in a Stock Award shall be forfeitable or otherwise
restricted for a period of

                                       13
<PAGE>
 
time or subject to such conditions as may be set forth in the Agreement.  By way
of example and not of limitation, the restrictions may postpone transferability
of the shares or may provide that the shares will be forfeited if the
Participant separates from the service of the Company and its Related Entities
before the expiration of a stated period or if the Company, a Related Entity,
the Company and its Related Entities or the Participant fails to achieve stated
performance objectives.  The period that the shares are restricted shall be at
least three years; provided, however, that the period that the shares are
restricted shall be at least one year if the transferability, vesting or both is
subject to the satisfaction of performance objectives other than continued
employment.

8.03.      EMPLOYEE STATUS
           ---------------

           In the event that the terms of any Stock Award provide that shares
may become transferable and nonforfeitable thereunder only after completion of a
specified period of employment, the Administrator may decide in each case to
what extent leaves of absence for governmental or military service, illness,
temporary disability, or other reasons shall not be deemed interruptions of
continuous employment.

8.04.      CHANGE IN CONTROL
           -----------------

           Sections 8.02 and 8.03 to the contrary notwithstanding, on and after
a Control Change Date or the first day following the commencement of a tender
offer or exchange offer for shares of Common Stock (other than one made by the
Company), provided that shares are acquired pursuant to such offer, each
outstanding Stock Award shall be transferable and nonforfeitable as of the
Control Change Date or the first day following such offer.

8.05.      SHAREHOLDER RIGHTS
           ------------------

           Prior to their forfeiture (in accordance with the applicable
Agreement and while the shares of Common Stock granted pursuant to the Stock
Award may be forfeited or are nontransferable), a Participant will have all
rights of a shareholder with respect to a Stock Award, including the right to
receive dividends and vote the shares; provided, however, that during such
period (i) a Participant may not sell, transfer, pledge, exchange, hypothecate,
or otherwise dispose of shares of Common Stock granted pursuant to a Stock
Award, (ii) the Company shall retain custody of the certificates evidencing
shares of Common Stock granted pursuant to a Stock Award, and (iii) the
Participant will deliver to the Company a stock power, endorsed in blank, with
respect to each Stock Award. The limitations set forth in the preceding sentence
shall not apply after the shares of Common Stock granted under the Stock Award
are transferable and are no longer forfeitable.

                           PERFORMANCE SHARE AWARDS
                           ------------------------
9.01.      AWARD
           -----

           In accordance with the provisions of Article IV, the Administrator
will designate each individual to whom an award of Performance Shares is to be
made and will specify the number of shares of Common Stock covered by each such
award.

9.02.      EARNING THE AWARD
           -----------------

           The Administrator, on the date of the grant of an award, shall
prescribe that the Performance Shares, or a portion thereof, will be earned, and
the Participant will be entitled to receive payment pursuant to the award of
Performance Shares, only upon the satisfaction of performance objectives or such
other criteria as may be prescribed by the Administrator and set forth in the
Agreement. By way of example and not of limitation, the performance objectives
or other criteria may provide that the Performance Shares will be earned only if
the Participant remains in the employ of the Company or a Related Entity for a
stated period or that the Company, a Related Entity, the Company and its Related
Entities or the Participant achieve stated objectives. The performance period
shall be at least three years; provided, however, that the performance period
shall be at least one year if the Agreement provides that the Performance Shares
will be earned upon the satisfaction of stated performance objectives other than
continued employment. No payments will be made with respect to Performance
Shares unless, and then only to the extent that, the Administrator certifies
that such objectives have been achieved.

9.03.      PAYMENT
           -------

     In the discretion of the Administrator, the amount payable when an award of
Performance Shares is earned may be settled in cash, by the issuance of Common
Stock or a combination of cash and Common Stock.  A fractional share shall not
be deliverable when an award of Performance Shares is earned, but a cash payment
will be made in lieu thereof.

9.04.      SHAREHOLDER RIGHTS
           ------------------

     No Participant shall, as a result of receiving an award of Performance
Shares, have any rights as a shareholder until and to the extent that the award
of Performance Shares is earned and settled by the issuance of Common Stock.
After an award of Performance Shares is earned, if settled completely or
partially in Common Stock, a Participant will have all the rights of a
shareholder with respect to such Common Stock.

9.05.      NONTRANSFERABILITY
           ------------------

           Except as provided in Section 9.06, Performance Shares granted under
this Plan shall be nontransferable except by will or by the laws of descent and
distribution. No right or interest of a Participant in any Performance Shares
shall be liable for, or subject to, any lien, obligation, or liability of such
Participant.

9.06.      TRANSFERABLE PERFORMANCE SHARES
           -------------------------------

           Section 9.05 to the contrary notwithstanding, if the Agreement
provides, an award of Performance Shares may be transferred by a Participant to
the Participant's children, grandchildren, spouse, one or more trusts for the
benefit of such family members or a partnership in which such family members are
the only partners, on such terms and conditions as may be permitted under
Securities Exchange Commission Rule 16b-3 as in effect from time to time. The
holder of Performance Shares transferred pursuant to this section shall be bound
by the same terms and conditions that governed the Performance Shares during the
period that they were held by the Participant; provided, however that such
transferee may not transfer Performance Shares except by will or the laws of
descent and distribution.

9.07.      EMPLOYEE STATUS
           ---------------

           In the event that the terms of any Performance Share award provide
that no payment will be made unless the Participant completes a stated period of
employment, the Administrator may decide to what extent leaves of absence for
government or military service, illness, temporary disability, or other reasons
shall not be deemed interruptions of continuous employment.

9.08.      CHANGE IN CONTROL
           -----------------

           Section 9.02 to the contrary notwithstanding, each outstanding
Performance Share award shall be earned as of a Control Change Date or the first
day following the commencement of a tender offer or exchange offer (other than
one made by the Company), provided that shares are acquired pursuant to such
offer. The amount payable for such Performance Shares shall be settled in cash
or Common Stock or a combination of cash and Common Stock as determined by the
Administrator in its discretion as soon as practicable after the Control Change
Date or the first day following such tender offer or exchange offer.

                    ADJUSTMENT UPON CHANGE IN COMMON STOCK
                    --------------------------------------

     The maximum number of shares as to which Options, SARs, Performance Shares
and Stock Awards may be granted under this Plan and the terms of outstanding
Stock Awards, Options, Performance Shares and SARs, shall be adjusted as the
Committee shall determine to be equitably required in the event that (a) the
Company (i) effects one or more stock dividends, stock split-ups, subdivisions
or consolidations of shares or (ii) engages in a transaction to which Section
424 of the Code applies or (b) there occurs any other event which, in the
judgment of the Committee necessitates such action.  Any determination made
under this Article X by the Committee shall be final and conclusive.

     The issuance by the Company of shares of stock of any class, or securities
convertible into shares of stock of any class, for cash or property, or for
labor or services, either upon direct sale or upon the exercise of rights or
warrants to subscribe therefor, or upon conversion of shares or obligations of
the Company convertible into such shares or other securities, shall not affect,
and no adjustment by reason thereof shall be made with respect to, the maximum
number of shares as to which Options, SARs, Performance Shares and Stock Awards
may be granted or the terms of outstanding Stock Awards, Options, Performance
Shares or SARs.

     The Committee may make Stock Awards and may grant Options, SARs and
Performance Shares in substitution for performance shares, phantom shares, stock
awards, stock options, stock appreciation rights, or similar awards held by an
individual who becomes an employee of the Company or a Related Entity in
connection with a transaction or event described in the first paragraph of this
Article X.  Notwithstanding any provision of the Plan (other than the limitation
of Section 5.02), the terms of such substituted Stock Awards or Option, SAR or
Performance Shares grants shall be as the Committee, in its discretion,
determines is appropriate.



                                  ARTICLE XI

             COMPLIANCE WITH LAW AND APPROVAL OF REGULATORY BODIES
             -----------------------------------------------------

     No Option or SAR shall be exercisable, no Common Stock shall be issued, no
certificates for shares of Common Stock shall be delivered, and no payment shall
be made under this Plan except in compliance with all applicable federal and
state laws and regulations (including, without limitation, withholding tax
requirements), any listing agreement to which the Company is a party, and the
rules of all domestic stock exchanges on which the Company's shares may be
listed.  The Company shall

                                       17
<PAGE>
 
have the right to rely on an opinion of its counsel as to such compliance.  Any
share certificate issued to evidence Common Stock when a Stock Award is granted,
a Performance Share is settled or for which an Option or SAR is exercised may
bear such legends and statements as the Administrator may deem advisable to
assure compliance with federal and state laws and regulations.  No Option or SAR
shall be exercisable, no Stock Award or Performance Share shall be granted, no
Common Stock shall be issued, no certificate for shares shall be delivered, and
no payment shall be made under this Plan until the Company has obtained such
consent or approval as the Administrator may deem advisable from regulatory
bodies having jurisdiction over such matters.



                                  ARTICLE XII

                               GENERAL PROVISIONS
                               ------------------

12.01.     EFFECT ON EMPLOYMENT AND SERVICE
           --------------------------------

           Neither the adoption of this Plan, its operation, nor any documents
describing or referring to this Plan (or any part thereof), shall confer upon
any individual any right to continue in the employ or service of the Company or
a Related Entity or in any way affect any right or power of the Company or a
Related Entity to terminate the employment or service of any individual at any
time with or without assigning a reason therefor.

12.02.     UNFUNDED PLAN
           -------------

           The Plan, insofar as it provides for grants, shall be unfunded, and
the Company shall not be required to segregate any assets that may at any time
be represented by grants under this Plan. Any liability of the Company to any
person with respect to any grant under this Plan shall be based solely upon any
contractual obligations that may be created pursuant to this Plan. No such
obligation of the Company shall be deemed to be secured by any pledge of, or
other encumbrance on, any property of the Company.

12.03.     RULES OF CONSTRUCTION
           ---------------------

           Headings are given to the articles and sections of this Plan solely
as a convenience to facilitate reference. The reference to any statute,
regulation, or other provision of law shall be construed to refer to any
amendment to or successor of such provision of law.

                                       18
<PAGE>
 
12.04.     TAX WITHHOLDING
           ---------------

           Each Participant shall be responsible for satisfying any income and
employment tax withholding obligation attributable to participation in this
Plan. In accordance with procedures established by the Administrator, a
Participant may surrender shares of Common Stock, or receive fewer shares of
Common Stock than otherwise would be issuable, in satisfaction of all or part of
that obligation.

12.05.     LIMITATION ON BENEFITS
           ----------------------

              (a) Despite any other provision of this Plan, if the Accounting
Firm determines that receipt of benefits or payments under this Plan would
subject a Participant to tax under Code section 4999, it must determine whether
some amount of the benefits or payments would meet the definition of a "Reduced
Amount." If the Accounting Firm determines that there is a Reduced Amount, the
total benefits and payments must be reduced to such Reduced Amount, but not
below zero.

              (b) If the Accounting Firm determines that the benefits and
payments should be reduced to the Reduced Amount, the Company must promptly
notify the Participant of that determination, including a copy of the detailed
calculations by the Accounting Firm. All determinations made by the Accounting
Firm under this section are binding upon the Company and the Participant.

              (c) It is the intention of the Company and the Participant to
reduce the benefits and payments under this Plan only if the aggregate Net After
Tax Receipts to the Participant would thereby be increased. As a result of the
uncertainty in the application of Code section 4999 at the time of the initial
determination by the Accounting Firm under this section, however, it is possible
that amounts will have been paid or distributed under the Plan to or for the
benefit of a Participant which should not have been so paid or distributed
("Overpayment") or that additional amounts which will not have been paid or
distributed under the Plan to or for the benefit of a Participant could have
been so paid or distributed ("Underpayment"), in each case, consistent with the
calculation of the Reduced Amount. If the Accounting Firm, based either upon the
assertion of a deficiency by the Internal Revenue Service against the Company or
the Participant which the Accounting Firm believes has a high probability of
success or controlling precedent or other substantial authority, determines that
an Overpayment has been made, any such Overpayment must be treated for all
purposes as a loan ab initio for which the Participant must repay the Company
together with interest at the applicable federal rate under Code section
7872(f)(2); provided, however, that no such loan may be deemed to have been made
and no amount shall be payable by Participant to the Company if and to the
extent such deemed loan and payment would not either reduce the amount on which
Participant is subject to tax under Code section 1 or 4999 or generate a refund
of such taxes. If the Accounting Firm, based upon controlling precedent or other
substantial authority, determines that an Underpayment has occurred, the
Accounting Firm must promptly notify the Administrator of the amount

                                       19
<PAGE>
 
of the Underpayment and such amount, together with interest at the applicable
federal rate under Code section 7872(f)(2), must be paid to the Participant.

rights of any beneficiary of a Guarantee against the Overnite Group to the
extent that UPC is required to make any payment under such Guarantee. UPC agrees
not to unilaterally terminate or withdraw any Guarantee and agrees to abide by
the terms of the Guarantees if, to UPC's knowledge after reasonable inquiry,
such termination, withdrawal or non-compliance would cause more than a de-
minimis liability to the Overnite Group or result in the Overnite Group's
default under or violation of the terms of any agreement with a third party.
 
     7.  Collateral.     (a)  So long as the Guaranty relating to the Japanese
         -----------                                                          
Lease Financing, identified as Item 1 on Schedule A hereto, remains in effect or
otherwise continues to apply to UPC, Overnite agrees that it shall meet the
financial covenants which are contained in Article VI of the Bank Credit
Agreement as if such covenants were set forth in this Agreement.  During the
period that Overnite is required to comply with the foregoing covenants under
the terms hereof, the Overnite Group shall promptly notify UPC if it ever fails
to comply with any such covenant, and shall furnish to UPC such information
respecting the condition or operations, financial or otherwise, of the Overnite
Group, as UPC may from time to time reasonably request.

     (b) In the event that the Overnite Group fails to comply with Section 5(a),
UPC may request, and the Overnite Group shall promptly deposit with UPC,
Collateral (as defined below) having a value equal to  the maximum amount then
payable upon termination of the Japanese Leveraged Lease referred to above,
including any repayment of debt or equity investment required in connection with
such termination.  For purposes of this Agreement, the term ACollateral@ shall
mean (i) cash; (ii) U.S. Treasury Bills maturing not more than 180 days from the
date of delivery thereof by the Overnite Group to UPC; (iii) commercial paper
(other than the commercial paper of a party hereto or its Affiliates)
denominated in U.S. dollars, provided that such commercial paper (A) continues
to be rated at least "A-1" by Standard & Poor's Corporation and AP-1" by Moody's
Investors Service Inc., or the equivalent ratings by two nationally recognized
investment rating services, or, if unrated, is guaranteed by a company having
outstanding commercial paper that is so rated, (B) remains readily marketable
and is not convertible into capital stock, and (C) matures not more than 180
days from the date of delivery to UPC; (iv) an irrevocable standby letter of
credit, in a form and issued by a bank reasonably acceptable to UPC; and (v) any
payments or other distributions received with respect to any of the aforesaid
Collateral.  For purposes of this Agreement, non-cash Collateral shall be valued
at market value, except that any letters of credit shall be valued at the face
amount thereof. The Overnite Group shall deposit any Collateral no later than
one Business Day following the date UPC's request therefor is received, into one
or more accounts identified by UPC which reasonably identify the Overnite
Group's ownership interest and UPC's security interest  in such Collateral.

     (c)  If on any Business Day the value of the aggregate Collateral then on
deposit exceeds the Collateral required to be on deposit pursuant to this
Agreement, then UPC, within one Business Day of the Overnite Group's demand
therefor, shall return such excess amount of Collateral to the Overnite Group;
provided, however, that UPC shall not be required to return Collateral that it
would otherwise be obligated to return to the extent any claims have been
asserted against UPC

                                     -13-
<PAGE>
 
for payment under the Guaranty referred to in Section 7(a) above or if the
Overnite Group has failed to make any indemnity payment required under this
Agreement with respect to such Guaranty. UPC may, at its option, satisfy its
obligation under this Section 7(c) through the return of cash or non-cash
Collateral, or both.

     (d) The Overnite Group shall earn interest on its cash Collateral from and
including the date of deposit to but excluding the date such Collateral is
returned at a rate per annum equal to the rate at which the account designated
by UPC actually bears interest (UPC to use reasonable efforts to obtain the
highest interest rate for liquid deposits in such amount from time to time
offered by its bank).  Such interest shall be calculated in accordance with the
usual practices of the bank at which such account is established.  UPC shall
remit interest to an account designated by the Overnite Group within three
Business Days of its demand therefor; provided that such payment shall not be
required more frequently than on a quarterly basis.

     (e) In the event the Collateral requirements of this Section 7 are
applicable, as security for the payment of all amounts due or that may become
due by the Overnite Group to or on behalf of UPC in accordance with this
Agreement with respect to the Guaranty referred to in Section 7(a), above, the
Overnite Group hereby grants to UPC a security interest in all Collateral and
all payments thereon and proceeds thereof, and additions thereto and
substitutions therefor, which are and may hereafter be delivered or otherwise
transferred to UPC by the Overnite Group in accordance with the provisions of
this Agreement, and the Overnite Group hereby agrees to take all actions
reasonably requested by UPC in order to perfect the security interest granted
hereunder. UPC may apply Collateral on deposit with it pursuant to this Section
7 to satisfy the indemnity obligations of the Overnite Group with respect to the
Guaranty referred to in Section 7(a), above, if and when payment of such amounts
has not been made or received.
 
     8.  Third Party Claims.  (a) If any person entitled to indemnification
         ------------------                                                
under this 

                                     -14-
<PAGE>
 
Agreement (an "Indemnitee") receives notice of the assertion of any
claim or of the commencement of any action or proceeding by any person that is
not a party to this Agreement or a subsidiary of any such party (a "Third Party
Claim") against such Indemnitee, the Indemnitee shall promptly provide written
notice thereof (including a description of the Third Party Claim and an estimate
of any Indemnifiable Losses (which estimate shall not be conclusive as to the
final amount of such Indemnifiable Losses)) to the party required to provide
indemnification under this Agreement (the "Indemnifying Party") within 10
calendar days after the Indemnitee's receipt of notice of such Third Party
Claim.  Any delay by the Indemnitee in providing such written notice shall not
relieve the Indemnifying Party of any liability for indemnification hereunder
except to the extent that the rights of the Indemnifying Party are materially
prejudiced by such delay.

          (b) The Indemnifying Party shall have the right to participate in or,
by giving written notice to the Indemnitee, to assume the defense of any Third
Party Claim at such Indemnifying Party's expense and by such Indemnifying
Party's own counsel (which shall be reasonably satisfactory to the Indemnitee),
and the Indemnitee will cooperate in good faith in such defense. The Indemnitee
may retain its own counsel with respect to such Third Party Claims, but the
Indemnifying Party shall not be liable for any legal expenses incurred by the
Indemnitee after the Indemnitee has received notice of the Indemnifying Party's
intent to assume the defense of a Third Party Claim, unless the named parties to
such Third Party Claim (including any impleaded parties) include both the
Indemnifying Party and the Indemnitee and representation of both parties by the
same counsel would be inappropriate due to actual or potential differing
interests between them. If the Indemnifying Party fails to take steps reasonably
necessary to diligently pursue the defense of such Third Party Claim within 10
days of receipt of notice from the Indemnitee that such steps are not being
taken, the Indemnitee may assume its own defense and the Indemnifying Party
shall be liable for the reasonable costs thereof.

          (c) The Indemnifying Party may settle any Third Party Claim which it
has

                                     -15-
<PAGE>
 
elected to defend so long as the written consent of the Indemnitee to such
settlement is first obtained (which consent shall not be unreasonably withheld).
The Indemnified Party shall not settle any Third Party Claim without the written
consent of the Indemnifying Party unless the Indemnifying Party elects not to
defend such Third Party Claim.

          (d) In the event that a Third Party Claim involves a proceeding as to
which both the UPC Group and the Overnite Group may be Indemnifying Parties, the
parties hereto agree to cooperate in good faith in a joint defense of such Third
Party Claim.

          (e) Notwithstanding subsections (b), (c), and (d) of this Section 8,
the provisions of Article IV, V, and VI of that certain Tax Allocation Agreement
entered into by Union Pacific Corporation, Overnite, OHI, and OTC of even date
herewith (the "Tax Allocation Agreement") shall control and supercede this
Agreement with respect to any Third Party Claim by a taxing authority.
 
     9.   Contribution.  If the indemnification provided for in this Agreement
          ------------                                                        
with respect to Overnite Securities Liabilities or UPC Securities Liabilities is
for any reason held by a court or other tribunal to be unavailable on policy
grounds or otherwise, the UPC Group and the Overnite Group shall contribute to
the Indemnifiable Losses in such proportion as to reflect each party's relative
fault in connection with such Indemnifiable Losses. The relative fault of the
parties shall be determined by reference to, among other things, whether the
conduct or information giving rise to the Indemnifiable Losses is attributable
to the UPC Group or the Overnite Group and each party's relative intent, access
to information and opportunity to prevent or correct the Indemnifiable Losses.
No person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the 1933 Act) shall be entitled to contribution from any person who is
not guilty of fraudulent misrepresentation.

     10.  Cooperation.  So long as any books, records and files retained by the
          -----------

operations or assets of the Overnite Group remain in existence and available,
the UPC Group and the Overnite Group shall have the right upon prior written
notice to inspect and copy the same at any time during business hours for any
proper purpose, provided that such right will not extend to any books, records
and files, disclosure of which in accordance herewith would result in a waiver
of the attorney-client, work product or other privileges which permit non-
disclosure of otherwise relevant material in litigation or other proceedings, or
which are subject on the date hereof and at the time inspection is requested to
a non-disclosure agreement with a third party and a waiver cannot reasonably be
obtained,  provided that, in the case of material requested of the Overnite
Group, such request relates only to the businesses, operations or assets of the
Overnite Group as constituted on or prior to Closing or books, records and files
reasonably required by the UPC Group for tax, accounting or financial reporting
purposes or to enforce its rights under this Agreement or any other agreement
executed by the Overnite Group and the UPC Group in connection with the Offering
or Acquisition. The UPC Group and the Overnite Group agree that they shall not
destroy any such books, records or files without reasonable notice to the other
party or if such party receives within 10 days of such notice any reasonable
objection from the other party to such destruction. Except in the case of
dispute between the parties hereto, the UPC Group and the Overnite Group shall
cooperate with one another in a timely manner in any administrative or judicial
proceeding involving any matter affecting the actual or potential liability of
either party hereunder. Such cooperation shall include, without limitation,
making available to the other party during normal business hours all books,
records and information, and officers and employees (without substantial
disruption of operations or employment) necessary or useful in connection with
any inquiry, audit, investigation or dispute, any litigation or any other matter
requiring any such books, records, information, officers or employees for any
reasonable business purpose. The party requesting or otherwise entitled to any

                                     -17-

books, records, information, officers or employees pursuant to this Section 10
shall bear all reasonable out-of-pocket costs and expenses (except for salaries,
employee benefits and general overhead) incurred in connection with providing
such books, records, information, officers or employees. Notwithstanding the
foregoing, the provisions of this Section 10 shall not affect the rights and
obligations of the parties under the Tax Allocation Agreement.
 
     11.  Section 338 Elections and Related Matters.   (a)    Overnite agrees
          -----------------------------------------

cause the appropriate affiliate or affiliates of Overnite to make) any and all
similar elections available under any applicable state or local law with respect

Subelections"). Overnite further agrees (x) to cause to be made express
elections under Section 338(g) of the Code and the regulations thereunder to the

"Section 338(g) Elections"), and (y) to make any and all similar elections
available under any applicable state or local law, to the extent necessary to
allow any Section 338(h)(10) Subelection to be made (the "Section 338(g)

          (b) As requested from time to time by UPC (whether before, at, or

necessary information to UPC in connection with, the preparation of Internal
Revenue Service Form 8023, Elections Under Section 338 For Corporations Making
Qualified Stock Purchases, and any comparable or related forms required under

Elections and the Section 338(g) Elections and any Section 338(h)(10)
Subelections and any Section 338(g) Subelections.  Without limiting the

same to UPC at the Closing. If UPC determines at or after the Closing that any
change is to be made in a Section 338 Election Form previously executed by

may prepare a new Section 338 Election Form and deliver such new Section 338
Election Form to Overnite, and Overnite shall cause such Section 338 Election
Form to be duly executed by Overnite or an affiliate of Overnite, as

necessary or appropriate to effect the timely filing of any other Section 338
Election Forms required to be filed for any applicable state or local tax
purposes.

          (d) With respect to the filings described in Section 11 (c) above,
Overnite, OHI, OTC and UPC will (i) treat as valid the Section 338(h)(10)
Elections and the Section 338(g) Elections with respect to the Acquisition and
the deemed acquisition of OTC, and any Section 338(h)(10) Subelections and any
Section 338(g) Subelections, (ii) not take any action inconsistent with such

returns in the manner prescribed by applicable regulations or other applicable
law).

          (e) Overnite, OHI, and OTC, on the one hand, and UPC, on the other

                              SERVICES AGREEMENT
                              ------------------


     THIS SERVICES AGREEMENT (the "Agreement") is made and entered into as of
the _______ day of August, 1998 by and between Union Pacific Corporation, a Utah
corporation ("UPC"), and Overnite Corporation, a Virginia corporation
("Overnite").

     WHEREAS, Overnite intends to issue and sell or cause to be issued and sold
all of its outstanding common stock through an initial public offering (the
closing of which is hereafter referred to as the "Offering"); and

     WHEREAS, immediately following the Offering, Overnite intends to purchase
all of the issued and outstanding common stock of Overnite Holding, Inc., a
Delaware corporation ("OHI"), from UPC (the "Acquisition"), with the result that
Overnite will become a publicly-owned company and OHI will become a wholly-
owned, direct subsidiary of Overnite; and

     WHEREAS, Overnite Transportation Company, a Virginia corporation ("OTC"),
is a wholly-owned, direct subsidiary of OHI and immediately following the
Acquisition will become a wholly-owned, indirect subsidiary of Overnite; and

     WHEREAS, UPC has historically provided to its subsidiaries, including OHI
and OTC, certain corporate and administrative services more particularly
described hereinafter; and

     WHEREAS, UPC and Overnite desire that UPC continue to provide such services
following the Offering and Acquisition pursuant to the terms and conditions of
this Agreement.

     NOW, THEREFORE, in consideration of the mutual promises and covenants
herein contained, the parties hereto agree as follows:

     1.   Services.  Following the Offering and Acquisition, UPC will provide or
          --------                                                              
cause to be provided to Overnite and its subsidiaries , those corporate and
administrative services described in Exhibit A hereto (the "Services").  The
scope of the Services shall be adjusted by the parties as needed to conform to
good business practice and the requirements of applicable laws, regulations and
tariffs, and as otherwise agreed to by the parties.

     2.   Charges for Services.  (a) In consideration for the Services provided
          --------------------                                                 
or caused to be provided, Overnite agrees to pay the following charges to UPC:
<PAGE>
 
          (i)   Charges for Services performed by UPC through a third party
     (other than a subsidiary of UPC) shall be equal to the final invoiced costs
     charged by such third party to perform those Services. With respect to all
     other Services not to be provided through such a third party, UPC and
     Overnite will negotiate in good faith fees to be charged on a quarterly or
     one-time basis depending on the Services to be provided. Fees for Services
     provided directly by UPC or a subsidiary of UPC shall, unless specifically
     addressed in Exhibit A hereto, be based on the estimated costs of providing
     such Services, which shall include a reasonable allocation of direct and
     indirect overhead costs (including, without limitation, employee salaries,
     benefits and other costs and reasonable travel and other out-of-pocket
     expenses expected to be incurred in connection therewith).

          (ii)  So long as any Services are provided hereunder, UPC and Overnite
     will review all fees negotiated hereunder and the scope of Services being
     provided on a quarterly basis.  If either party believes that the actual
     cost of providing the Services represented by such fees will vary by at
     least 10% of the then current cost of providing such Services, the parties
     hereto will negotiate in good faith new fees reflecting such variation.
     All new fees shall apply prospectively only and no adjustment will be made
     to fees payable with respect to a preceding quarter.

          (iii) If any additional Services are included hereunder,  or if the
     scope or nature of Services provided at any time under this Agreement
     changes significantly, the parties hereto will negotiate in good faith new
     fees based on the estimated cost of providing such additional or revised
     Services, as contemplated in Section 2(a)(i).

          3.    Payments. (a) UPC shall submit to Overnite by the 10th working
                --------                                                      
day of each quarter an invoice for all charges associated with Services provided
during the preceding quarter, including any other amounts payable in respect of
the preceding quarter.  All invoices shall describe in reasonable detail the
Services provided and the charges associated therewith, any related adjustments
and any other amounts that are payable.  Except as provided in subparagraph  (b)
below, Overnite shall remit payment in full for all charges invoiced on or
before the last working day of the month in which the invoice is received.
Payment of all invoices shall be made by wire transfer of

                                      -2-
<PAGE>
 
immediately available funds to an account or accounts designated by UPC.  Any
late payment shall bear interest at the rate of 1% per month or fraction thereof
until paid.

          (b)  In the event of a dispute as to an invoiced amount, Overnite
shall promptly pay all undisputed amounts, but shall be entitled to withhold
amounts in dispute, and shall promptly notify UPC of such dispute and the basis
therefor. The parties agree to provide each other with sufficient records and
information to resolve such dispute and, without limiting the rights and
remedies of the parties hereunder, to negotiate in good faith a resolution
thereto. Notwithstanding this clause (b), the late payment interest provision in
Section 3(a) shall apply to all such withheld amounts that are ultimately
determined to be due.

     4.   Term of Agreement.  The term of this Agreement shall commence
          -----------------                                            
immediately following the Offering and Acquisition and shall continue thereafter
unless terminated by agreement of the parties hereto.  Notwithstanding the
foregoing, this Agreement shall become terminable, upon not less than 30 days'
prior written notice (i) with respect to any Services or any part thereof, at
any time by Overnite, or (ii) in whole or in part with respect to any Services,
at any time by UPC on or after the 18th month following the Offering except for
Services or any part thereof described in Item 6 to Exhibit A hereto which may
be terminated at any time by UPC following 30 days prior written notice.
Termination under this Paragraph  4 or otherwise shall have no effect on the
obligations of the parties to provide Services prior to the effective date of
such termination or to make payments in respect of charges incurred in
connection therewith or which relate to events occurring prior to such date.

     5.   Performance of Services.  (a) UPC shall perform the Services or cause
          -----------------------                                              
the Services to be performed with the same degree of care, skill and prudence
customarily exercised for its own operations.  It is understood and agreed that
the Services will be substantially identical in nature and quality to the
Services performed by UPC for OTC and its subsidiaries during the year prior to
the commencement of the term of this Agreement, except as required by Overnite's
becoming a public company after the Offering.

          (b)  Each party acknowledges that the Services will be provided only
with respect to the businesses of Overnite and its subsidiaries as such
businesses exist immediately following the Offering and Acquisition or as
otherwise mutually agreed by the parties.  Services will not be

                                      -3-
<PAGE>
 
requested for the benefit of any entity other than Overnite and its
subsidiaries.  Overnite agrees that it will use the Services only in accordance
with all applicable federal, state and local laws, regulations and tariffs and
in accordance with the reasonable conditions, rules, regulations and
specifications which are or may be set forth in any manuals, materials,
documents or instructions of UPC.  UPC reserves the right to take all actions,
including the termination of any Services or part thereof, in order to assure
that the Services are provided in accordance with any applicable laws,
regulations and tariffs.

          (c)  Any input or information needed by either party to perform or
utilize the Services pursuant to the provisions of this Agreement shall be
provided by the other party or its subsidiaries, as the case may be, in a manner
consistent with the practices employed by the parties during the year prior to
the Offering.  Should the failure by Overnite to provide such input or
information render the performance of the Services impossible or unreasonably
difficult, UPC may, upon reasonable notice, refuse to provide such Services.

     6.   Liability and Indemnification.  Except as provided below, UPC shall
          -----------------------------                                      
have no liability under this Agreement for damage or loss of any type suffered
by Overnite or its subsidiaries or any third party as a result of the
performance or non-performance of the Services. Each party shall indemnify,
defend and hold the other party harmless from and against all damages, losses
and out-of-pocket expenses (including fees and disbursements of counsel) caused
by or arising out of any willful breach or gross negligence by such indemnifying
party in the performance or non-performance of any obligation or agreement
contained herein or by the willful misconduct of such indemnifying party. In the
event of a claim against UPC by a third party, Overnite shall indemnify, defend
and hold UPC harmless from and against all damages, losses and out-of-pocket
expenses (including fees and disbursements of counsel) caused by or arising out
of the performance or non-performance of the Services, except where caused by
the willful breach or negligence of UPC or UPC's willful misconduct.
Notwithstanding any other provision of this Agreement,  UPC shall have no
liability for the acts or omissions of any third party (other than a subsidiary
of UPC) that provides Services hereunder so long as UPC has not been grossly
negligent in the selection of such third party.  For purposes of this section,
Services shall include services performed by UPC pursuant to the Tax Allocation
Agreement, dated August __, 1998, between UPC and Overnite, OHI and OTC.

     7.   Confidentiality.  The parties each agree to hold in trust and maintain
          ---------------                                                       
confidential, and, except as required by law or applicable rules and regulations
promulgated thereunder or by court order or other legal process, not to disclose
to others without first obtaining the prior written approval of the other party,
any information received by it from the other party or developed or otherwise
obtained by it under this Agreement, including all information resulting from
the provision or utilization of the Services hereunder (collectively, the
"Information").  At the time of termination of this Agreement in whole or in
part, each party shall, within 90 days after the effective date of such
termination, return to each other all written Information that it obtained and
shall not retain or allow any third party to retain photocopies or other
reproductions of such Information, provided that (i) the parties may retain any
Information to the extent reasonably needed to comply with applicable tax,
accounting or financial reporting requirements or to resolve any legal  issues
identified at the time of termination, and (ii) in the case of a partial
termination of this Agreement, the parties may retain any Information required
to perform or utilize any remaining Services covered by this Agreement.
Alternatively, each party may, upon receipt of the written consent of the other
party, destroy such Information instead of returning the same pursuant to the
foregoing sentence.  The obligations set forth in this Paragraph 7 shall not
apply to any Information which is shown by either party to be or have become
knowledge generally available to the public other than through the acts or
omissions of such party.

     8.   Assignment.  Neither party shall assign or transfer any of its rights
          ----------                                                           
or delegate any of its obligations under this Agreement without first obtaining
the prior written consent of the other party, which consent may be withheld by
such other party in its sole discretion; provided that UPC shall be permitted to
cause any Services to be provided on UPC's behalf through one or more third
parties selected by UPC; and provided further that the selection of any third
party by UPC shall be subject to the prior written consent of Overnite (which
shall not be unreasonably withheld or delayed) unless such third party shall
have provided the same or similar Services to UPC or its affiliates at any time
during the 12 months immediately preceding the Offering.  This Agreement shall
be binding upon and inure to the benefit of the parties hereto and their
successors and permitted assigns.

the net amount of all taxes actually incurred by a party as a result of an
action (or failure to act) by another party with respect to matters described in
this Agreement, taking into account the anticipated out-of-pocket costs of
resolving administrative disputes and 

                                       5
<PAGE>
 
litigation with the taxing authorities over the action or failure to act and the
likelihood of prevailing (based on the assumption that the taxing authorities
would challenge the desired tax treatment). Such tax resulting from such action
(or failure to act) shall be calculated using the allocated Federal Income Tax,
Environmental Tax, or Unitary Income Tax liability for the appropriate tax
jurisdiction, net of the present value of reasonably anticipated related future
offsetting tax benefits (based upon the tax law in effect at the time of
computation) discounted at a rate of ten percent (10%) per annum.

                                TAX ALLOCATIONS


     3.1  Consolidated Federal Income Tax; Environmental Tax.
          ---------------------------------------------------

     (a) The Overnite Consolidated Group's share of consolidated Federal Income
Tax and Environmental Tax liabilities for the tax periods beginning on or after
January 1, 1991, shall be allocated in accordance with subsections (b) and (c)
hereof.

     (b) The Overnite Consolidated Group's Federal Income Tax liability, or tax
benefit in the event of a loss, shall be determined jointly by UPC and  Overnite
Corporation based upon separate Items of the Overnite Consolidated Group to the
extent such Items were included in the Combined Consolidated Group's tax returns
as filed or finally adjusted and resulted in either a marginal tax cost or
benefit to the Combined Consolidated Group.  In general, the Federal Income Tax
cost or benefit to be allocated to the Overnite Consolidated Group shall be
equal to the difference between the Federal Income Tax actually payable by the
Combined Consolidated Group for a period and the amount of Federal Income Tax
which would have been payable by the Combined Consolidated Group for such period
if the Overnite Consolidated Group Items for such period had not been included
in the Combined Consolidated Group's tax returns for such period, provided that
the allocation principles enumerated in Appendix I to this Agreement shall
control to the extent such principles are inconsistent with the foregoing.
Except as otherwise specifically provided in this Agreement, for all periods
when UPC owns directly or indirectly 100% of the outstanding stock of Overnite
Holding or 

                                       8
<PAGE>
 
Overnite, the computation of the Overnite Consolidated Group's Federal Income
Tax liability or tax benefit shall not reflect any limitations it would have
suffered or benefits it would have realized if it had filed its return on a
stand-alone basis, but rather shall reflect its allocation of Federal Income Tax
costs or benefits actually realized, either as originally reported or adjusted
upon audit, amended return, or ultimate settlement, or otherwise realized by the
Combined Consolidated Group for any period.

     (c) The Overnite Consolidated Group's Environmental Tax liability shall be
determined jointly by UPC and  Overnite Corporation and shall be equal to the
amount of Environmental Tax which would be owed by the Overnite Consolidated
Group on a stand-alone basis.

     (d) Notwithstanding the foregoing, all items of income, gain, loss, or
deduction attributable to UPC's sale of the stock of Overnite Holding to
Overnite Corporation after the IPO pursuant to that certain Stock Purchase and
Indemnification Agreement between the Parties (the "Purchase Agreement"), and
the deemed sales of Overnite Holding's assets and Overnite's assets pursuant to
elections under Section 338(h)(10) of the Code shall be allocated to the UPC
Consolidated Group, except as set forth in the next following sentence.  Any
item of income or gain attributable to pre-IPO contingent liabilities of the
Overnite Consolidated Group which become payable or are otherwise accrued at or
after the IPO and result in additional amounts realized under Section 338 of the
Code shall be allocated to the Overnite Consolidated Group except to the extent
the UPC Consolidated Group receives the benefit of corresponding and offsetting
deductions.

     3.2  Unitary Income Taxes.
          -------------------- 

                                       9

     (a) The Overnite Consolidated Group's share of Unitary Income Tax
liabilities for the tax periods beginning on or after January 1, 1991, shall be
allocated in accordance with subsections (b) and (c) hereof.

     (b) The total Unitary Income Tax liability due to a taxing jurisdiction
where members of the Overnite Consolidated Group are included in a Unitary Group
with members of the UPC Consolidated Group shall be determined jointly by UPC
and Overnite Corporation and then allocated to the constituent Divisions in such
Unitary Group in accordance with the allocation principles enumerated in
Appendix II to this Agreement. Nexus both for purposes of the determination of
the Unitary Income Tax Liability in a particular jurisdiction and for purposes
of the allocation of such liability to constituent Divisions in the Unitary
Group shall be determined jointly by UPC and Overnite Corporation. Should a
particular taxing jurisdiction subsequently determine Nexus differently from a
determination previously used, the Unitary Income Tax liability shall be
governed by such taxing jurisdiction's sustained or agreed upon final
determination, and any additional Unitary Income Tax liabilities arising
therefrom shall be allocated among the constituent Divisions in the Unitary
Group in accordance with the allocation principles enumerated in Appendix II to
this Agreement.

     (c) Notwithstanding the foregoing, all items of unitary income, gain, loss,
or deduction attributable to UPC's sale of the stock of Overnite Holding to
Overnite Corporation after the IPO pursuant to the Purchase Agreement, and the
deemed sales of Overnite Holding's assets and Overnite's assets pursuant to
elections under Section 338(h)(10) of the Code (or the corresponding provisions
of state or local law) shall be allocated to the UPC Consolidated Group, except
as set forth in the next following 

                                       10
<PAGE>
 
sentence. Any item of income or gain attributable to pre-IPO contingent
liabilities of the Overnite Consolidated Group which become payable or are
otherwise accrued at or after the IPO and result in additional amounts realized
under Section 338 of the Code (or the corresponding provisions of state or local
law) shall be allocated to the Overnite Consolidated Group except to the extent
the UPC Consolidated Group receives the benefit of corresponding and offsetting
deductions.

     3.3 Miscellaneous Taxes. All liabilities for Miscellaneous Taxes shall
         -------------------                                               
remain the sole responsibility of the particular entity which incurred or whose
predecessor incurred the liability or whose activities (or predecessors'
activities) resulted in the liability, provided, however, that the IPO and
related transactions (including elections under Section 338(h)(10) of the Code
or the corresponding provisions of state or local law) shall not be considered
an activity of UPC for purposes of determining responsibility for Miscellaneous
Taxes.  Likewise, any additional Miscellaneous Taxes imposed, or refunds
received, as a result of audits, claims, amended returns, or any other reason
shall be the sole property or liability of the entity which incurred the
liability (or its successor) or is entitled to the refund or claim by operation
of law or under the terms of this Agreement.

     4.1  Estimated and Current Taxes.
          --------------------------- 

     (a) Overnite Corporation shall provide to UPC the separate tax data
necessary to determine the Overnite Consolidated Group's share of estimated
Federal Income Tax, 

                                       11
<PAGE>
 
Environmental Tax, and Unitary Income Tax ("Estimated Tax Payment") on such
schedule as is prescribed by UPC so that Estimated Tax Payments can be computed
and allocated in a timely fashion. On or before the due date for each Estimated
Tax Payment, UPC shall provide to Overnite Corporation a statement of the
Overnite Consolidated Group's allocable share of the Estimated Tax Payment to be
made. On or before such due date, Overnite Corporation shall pay to UPC the
amount of the Estimated Tax Payment identified in such statement.

     (b) Overnite Corporation shall provide to UPC the separate tax data
necessary to determine the share of the prior-year consolidated Federal Income
Tax, Environmental Tax, and Unitary Income Tax liability allocable to members of
the Overnite Consolidated Group.  Within 60 days of filing the tax returns, UPC
shall provide to Overnite Corporation a final statement of the Overnite
Consolidated Group's share of the actual prior-year consolidated Federal Income
Tax, Environmental Tax, and Unitary Income Tax liability. If the amount of the
Overnite Consolidated Group's prior-year tax liabilities exceeds the prior-year
Estimated Tax Payments previously remitted by members of the Overnite
Consolidated Group, Overnite Corporation shall pay to UPC the amount of such
excess. If the amount of the Overnite Consolidated Group's prior-year tax
liabilities is less than the prior-year Estimated Tax Payments previously
remitted by members of the Overnite Consolidated Group, UPC shall pay to
Overnite Corporation the amount of such difference. All such calculations shall
be made in accordance with Article III of this Agreement.

     4.2  Future Settlements. UPC shall give Overnite Corporation reasonable

claims, or amended returns is due from, or payable to, Overnite Corporation
under this Agreement. Overnite Corporation shall pay to UPC an amount equal to
the tax liabilities attributable to including the Overnite Consolidated Group in
the Combined Consolidated Group to the extent such tax liabilities were not
reflected in payments previously made by the members of the Overnite
Consolidated Group. UPC shall pay to Overnite Corporation an amount equal to the
tax benefits attributable to including the Overnite Consolidated Group in the
Combined Consolidated Group, to the extent that such tax benefits were not
previously paid to (or reflected in payments by) members of the Overnite
Consolidated Group. To the extent that all Items attributable to members of the
Overnite Consolidated Group for a tax period are finally settled or resolved but
a final settlement or resolution has not been reached with the taxing authority
because Items not attributable to members of the Overnite Consolidated Group
have not been settled or resolved, UPC shall pay Overnite Corporation its share
of such tax benefits, or Overnite Corporation shall pay UPC the Overnite
Consolidated Group's share of such tax liabilities, after the final settlement
or resolution of all such Items attributable to members of the Overnite
Consolidated Group. All such calculations shall be made in accordance with
Article III of this Agreement.

     4.3  Payments/Refunds.  Payments under this Agreement shall be made not
          ----------------                                                  
later than 11:00 a.m. (New York City time) on the day when due in U.S. dollars
by wire transfer of immediately available funds to the account designated for
that purpose by UPC or Overnite Corporation. Unless a different time is
specified for payment hereunder, such payments shall be due fifteen days after
appropriate notice is given that such payment is due. Whenever such payments
shall be stated to be due on a day other than a 

                                       13
<PAGE>
 
day on which banks are not required or authorized to close in New York City (a
"Business Day"), such payment shall be made on the next succeeding Business Day.
If an amount due hereunder shall not have been paid when due, such amount shall
bear interest from the date such payment is due, to but excluding the date of
payment of such amount, at a rate per annum equal to ten percent (10%). Interest
shall be calculated on the basis of a year of 365 or 366 days for the actual
number of days elapsed and compounded quarterly.

     4.4  Billing Disputes with Taxing Authorities. Where a taxing authority has
          ----------------------------------------                              
made or makes assessments, abatements, credits, refunds, or similar items or
posts payments, assessments, abatements, credits, refunds, or similar items on
or against one Party's tax account which are properly attributable hereunder to
the other Party's activities, the Parties shall cooperate with each other and
work together to resolve the billing discrepancies with the appropriate taxing
authority. Where the billing discrepancies cannot be resolved with the
appropriate taxing authority, the Parties shall make each other whole as if the
taxing authority had correctly posted the accounts of the Parties.

     5.1  Conduct of Audits; Amended Returns.
          ---------------------------------- 

     (a) UPC shall have responsibility and control with respect to the conduct
of audit examinations, extending the statute of limitations and choice of forum
in connection with 

                                       14
<PAGE>
 
audit examinations, and the filing of administrative refund claims or amended
returns for the Combined Consolidated Group and any member thereof (and for any
passthrough entity in which a member of the Combined Consolidated Group has an
interest) for consolidated Federal Income Tax, Environmental Tax, and Unitary
Income Tax liabilities for all periods beginning before the IPO. UPC shall
exercise such responsibility and control in a manner which lawfully Minimizes
the tax liabilities of the Combined Consolidated Group. UPC shall not exercise
such responsibility and control to jeopardize tax positions, elections, or other
items of the Overnite Consolidated Group, provided this is consistent with
lawfully Minimizing the tax liabilities of the Combined Consolidated Group.

     (b) The Parties shall cause all members of the Combined Consolidated Group,
and any passthrough entities in which a member has an interest, fully to
cooperate with each other during the course of any audit. UPC shall keep
Overnite Corporation advised of, and shall honor all reasonable requests by
Overnite Corporation to be involved in, the preparation of such claims and
amended returns and the audit process to the extent Overnite Consolidated Group
Items or issues are involved.

     (c) If Overnite Corporation shall determine that it is desirable for UPC,
Overnite Corporation, or a member of the Overnite Consolidated Group to file a
non-routine claim for refund or amended return with respect to any taxable
period beginning before the IPO, Overnite Corporation shall prepare and submit
such proposed claim to UPC, together with a reasoned legal analysis of the
merits of the proposed claim and a statement setting forth when the statute of
limitations on filing such claim will expire, in sufficient time for UPC to
consider and act on such proposed claim.

                                       15

     (d) Overnite Corporation may request that UPC not contest, or discontinue
the contest of, a consolidated Federal Income Tax, Environmental Tax, or Unitary
Income Tax issue relating to an Item of the Overnite Consolidated Group or its
members.  UPC shall comply with such request only if it determines, in its sole
and absolute discretion, that doing so would have no adverse effect upon the UPC
Consolidated Group.

     5.2  Protest; Litigation. If the consolidated Federal Income Tax,
          -------------------

Group (or any member thereof) or any other matter involving the Internal Revenue
Service with respect to any taxable period beginning before the IPO becomes or
has the potential to become the subject of litigation in any court or subject to
protest or any other administrative proceeding (including but not limited to
requests for rulings or technical advice memoranda), the decision to institute
the litigation or proceeding, the choice of forum, and the overall conduct of
the litigation or proceeding shall be the responsibility of, and shall be
controlled by, UPC. Such responsibility and control shall be exercised in a
manner which lawfully Minimizes the tax liabilities of the Combined Consolidated
Group. The Parties shall cause all members of the Combined Consolidated Group,
and any passthrough entities in which a member has an interest, fully to
cooperate with each other during the course of the litigation or proceeding. UPC
shall keep Overnite Corporation advised of, and shall honor all reasonable
requests by Overnite Corporation to be involved in, all litigation or
proceedings to the extent that Overnite Consolidated Group Items or issues are
involved.

     5.3  Opinion Procedure.
          ----------------- 

     (a) UPC shall hold Overnite Corporation harmless in the manner provided in

<PAGE>
 
Section 5.3(e) of this Agreement if

          (i) without Overnite Corporation's consent, UPC adjusts, compromises,
     or settles (or directs Overnite Corporation to adjust, compromise, or
     settle) a consolidated Federal Income Tax, Environmental Tax, or Unitary
     Income Tax issue relating to an Item of the Overnite Consolidated Group or
     its members;

          (ii) UPC fails to file (or directs Overnite Corporation not to file) a
     claim for refund or amended return submitted to UPC pursuant to Section
     5.1(d) of this Agreement; or

          (iii) over Overnite Corporation's written objection UPC takes (or
     directs Overnite Corporation to take) a consolidated Federal Income Tax,
     Environmental Tax, or Unitary Income Tax return position relating to an
     Item of the Overnite Consolidated Group or its members,

provided (x) with respect to clause (i) above a legal opinion is obtained that
the adjustment, compromise, or settlement does not reasonably reflect both the
likelihood of prevailing if the issue were fully and fairly litigated to a final
determination and the anticipated costs of resolving administrative disputes and
litigation with the taxing authorities, or (y) with respect to clauses (ii) and
(iii) above a legal opinion is obtained that Overnite Corporation's tax position
on the issue is more likely than not to prevail and to Minimize Tax Liabilities,
using the procedure (in the case of either (x) or (y) above) set forth in
Section 5.3(b) of this Agreement. This Section 5.3 shall not apply to an
adjustment, compromise, settlement, or return position which is preliminary to
commencing a refund claim or litigation in which such issue will be contested.
Article VIII of this Agreement shall not apply to any issue as to which a Party
invokes this 

                                       17
<PAGE>
 
opinion procedure.

     (b) If the Parties cannot agree within a reasonable time whether a return
position should be taken, or whether UPC should adjust, compromise, or settle an
Overnite Consolidated Group Item or file a claim for refund or amended return,
either Party can invoke the following opinion procedure as to such issue by
giving notice to the other. Within thirty (30) days of either Party's notice,
the Parties shall agree upon and simultaneously notify an outside law firm which
has recognized expertise in the field of taxation. Within thirty (30) days of
such notice to the law firm, the Parties shall supply to the law firm all
written support and supplementary documents which each Party deems necessary to
support its contention that the proposed adjustment, compromise, or settlement
does (or does not) reasonably reflect the likelihood of prevailing or that its
tax position on the issue under Section 5.3(a)(ii) or (iii) above is (or is not)
more likely than not to prevail. Either Party may discuss the issues with the
law firm prior to its decision, provided the other Party is given the
opportunity to be present. Within sixty (60) days of such notice to the law
firm,

          (i) with respect to an adjustment, compromise, or settlement described
     in clause (i) of Section 5.3(a), the law firm shall deliver to both Parties
     either (x) the law firm's reasoned opinion that such adjustment,
     compromise, or settlement reasonably reflects both the likelihood of
     prevailing on the issue if the issue were fully and fairly litigated to a
     final determination and the anticipated costs of resolving administrative
     disputes and litigation with the taxing authorities, or (y) if such
     adjustment, compromise, or settlement is not such a reflection, the law
     firm's reasoned opinion as to the likelihood (expressed as a percentage) of

                                       18
<PAGE>
 
     prevailing on the issue if fully and fairly litigated to a final
     determination and the law firm's good faith estimate of the anticipated
     costs (expressed in dollars) of resolving administrative disputes and
     litigation with the taxing authorities; or

          (ii) with respect to a claim for refund, amended return, or return
     position described in clauses (ii) or (iii) of Section 5.3(a), the law firm
     shall either (x) deliver its reasoned opinion to both Parties that, if the
     issue were fully and fairly litigated to a final determination, Overnite
     Corporation's tax position on the issue more likely than not would prevail,
     or (y) notify the Parties that the law firm cannot so opine. In the case of
     (x) above, the law firm shall also render its reasoned opinion as to the
     likelihood (expressed as a percentage) of prevailing on the issue if fully
     and fairly litigated to a final determination and the law firm's good faith
     estimate of the anticipated costs (expressed in dollars) of resolving
     administrative disputes and litigation with the taxing authorities.  If in
     the opinion of the law firm an expedited decision is necessary or advisable
     to protect either Party's rights, the law firm shall accelerate the dates
     for submissions and decision so as to protect the rights of the Parties. If
     the Parties so agree, inside tax counsel may be utilized instead of an
     outside law firm without affecting the remainder of this opinion procedure.

     (c) The Party whose position does not prevail under Section 5.3(b) shall
pay the fees and costs of the outside law firm used for the opinion procedure,
notwithstanding any contrary provision of this Agreement.

     (d) The determination made by the law firm (or inside tax counsel, as the
case may be) under Section 5.3(b) shall be conclusive and binding on the Parties
and shall not 

                                       19
<PAGE>
 
be subject to appeal, except in the case of manifest mathematical
error.

     (e) To the extent that the opinion procedure of this Section 5.3 is invoked
as to an Item (including but not limited to a Timing Item) and Overnite
Corporation prevails but Overnite Corporation's position with respect to the
Item is not adopted or implemented by UPC, the following reclassifications and
treatments shall occur for all purposes of this Agreement, including but not
limited to allocating tax costs or benefits related to such Item between the
Parties under Article III:

          (i) Overnite Corporation shall not be allocated the amount of any tax
     cost attributable to failure to adopt or implement Overnite Corporation's
     position with respect to the Item; and

          (ii) the benefit of the Turnaround of a Timing Item that is subject to
     the opinion procedure shall be reclassified and specially treated as a UPC
     Consolidated Group Item.

In the application of this Section 5.3(e), the principles contained in the
definition of the term Actual Loss shall apply.

     (f) At any time, the Parties may (by written agreement)  waive any portion
or all of this opinion procedure and reclassify or reallocate any Items as to
which a dispute arises within the contemplation of Section 5.3(b).

which is allocable or due to one Party from the other under this Agreement, or
on whether an action or failure to act has the effect of Minimizing taxes, then
either Party may invoke this procedure by giving notice to the other. Upon
receipt of such notice, the Parties shall select and notify a single public
accounting firm to resolve the dispute. If the Parties cannot agree on a single
firm within ten (10) days, they shall each select a nationally recognized public
accounting firm, which may include the public accounting firm which regularly
opines on either Party's financial statements ("Auditor"). Those two firms shall
jointly select and notify, within ten (10) days, a third independent nationally
recognized public accounting firm, which shall not be the Auditor of either
Party, to resolve the dispute. This Article VIII shall not apply to any issue as
to which a Party has invoked the

"Arbitrator") shall be provided with written arguments by each Party and all
supporting documents which each Party deems necessary within thirty (30) days of
selection of the Arbitrator. Each Party shall provide the other Party with
copies of all written arguments, documents, and correspondence submitted to the
Arbitrator. Either Party may discuss the issues with the Arbitrator provided the
other Party is given the opportunity to be present. Within sixty (60) days of
selection of the Arbitrator, the Arbitrator may request each Party to respond to
the written arguments provided by the other Party. The Arbitrator may also set a
date, time, and place for oral arguments. Within sixty (60) days of any oral
arguments or the last written arguments, whichever is later, the arbitrator
shall notify the Parties of its decision. If in the opinion of the Arbitrator an
expedited decision is necessary to protect either Party's rights, the Arbitrator
shall accelerate the dates for submissions, arguments, and decision so as to
protect the rights of the Parties.

     8.3  Binding Resolution. The determination made by the Arbitrator under

readopted and affirmed on behalf of any corporation which, subsequent to the
date hereof, becomes a member of the UPC Consolidated Group or the Overnite
Consolidated Group. UPC and Overnite Corporation shall, upon the written request
of the other, cause any of their respective subsidiaries formally to ratify and

                                  ----------

                       ALLOCATION OF FEDERAL INCOME TAX
                           LIABILITIES AND BENEFITS
                      ATTRIBUTABLE TO SPECIFIC TAX ITEMS

Pursuant to Section 3.1 of this Agreement, the  Overnite Consolidated Group
shall be allocated its pro rata contribution of Federal Income Tax cost or
benefit (either as originally filed or as adjusted upon audit, amended return,
or ultimate settlement, or otherwise), including interest and penalties, as a
result of the Combined Consolidated Group's activities for the applicable
periods. In general, the Federal Income Tax cost or benefit to be allocated to
the  Overnite Consolidated Group shall be equal to the difference between the
Federal Income Tax actually payable by the Combined Consolidated Group for a
period and the amount of Federal Income Tax which would have been payable by the
Combined Consolidated Group for such period if the  Overnite Consolidated
Group's Items for such period had not been included in the Combined Consolidated
Group's tax returns for such period, provided that the allocation principles
enumerated below shall control, subject to Section 3.1(d), to the extent such
principles are inconsistent with the foregoing:

     a. Net Operating Losses (NOLs). To the extent that the  Overnite
        ---------------------------                                  
Consolidated Group incurs an NOL, it shall be allocated the Federal Income Tax
benefit attributable to such loss when such benefit is realized (including
carrybacks) by the Combined 

                                      I-1
<PAGE>
 
Consolidated Group. If the Combined Consolidated Group does not fully utilize
the NOLs of all members of the Combined Consolidated Group for any period, the
Overnite Consolidated Group shall be allocated its pro rata share of the
Combined Consolidated Group's NOL benefit determined by multiplying such benefit
by a ratio the numerator of which is the NOL of the Overnite Consolidated Group
for such period and the denominator of which is the sum of the numerator and the
NOLs of any UPC Divisions which have an NOL for such period. The Overnite
Consolidated Group shall be allocated any tax benefit attributable to NOL
carryforwards when and to the extent the Combined Consolidated Group realizes
such benefit in a subsequent period as determined (on a first-in, first-out
basis) by applying the foregoing allocation principles in such subsequent
period.

     b. Capital Gains and Losses. To the extent that the Overnite Consolidated
        ------------------------                                              
Group realizes a net capital gain, the tax cost of such Item shall be determined
and allocated to the Overnite Consolidated Group at the applicable favorable
capital gain rate of tax, if any, for such Item for the period in question. To
the extent that the Overnite Consolidated Group realizes a net capital loss, the
Overnite Consolidated Group shall be allocated a tax benefit determined at the
applicable favorable capital gain rate, if any, but only when and to the extent
such net capital loss is fully utilized by the Combined Consolidated Group. To
the extent that the Combined Consolidated Group does not fully utilize the net
capital loss of the Combined Consolidated Group in any tax period, the net
capital loss of the Overnite Consolidated Group (for purposes of determining the
tax benefit) shall be limited to a pro rata share of the aggregate net capital
gains of the UPC Divisions which have net capital gains for the period, based on
a ratio the numerator of which is the net 

                                      I-2
<PAGE>
 
capital loss of the Overnite Consolidated Group for the period and the
denominator of which is the sum of the numerator and the net capital losses of
the UPC Divisions which have net capital losses for the period. The balance
shall be carried forward, and the Overnite Consolidated Group shall be allocated
the tax benefit when and to the extent the Combined Consolidated Group realizes
such benefit in a subsequent period as determined (on a first-in, first-out
basis) by applying the foregoing allocation principles in such subsequent
period.

     c. Section 1231 Gains and Losses.
        ----------------------------- 

     (1) To the extent that the Overnite Consolidated Group realizes a net
section 1231 gain (within the meaning of section 1231 of the Code), the tax cost
attributable to such Item shall be determined and allocated at the applicable
favorable rate of tax, if any, for items of section 1231 gain income for the tax
period in question. Where the  Overnite Consolidated Group realizes a net
section 1231 loss (within the meaning of section 1231 of the Code), but the
Combined Consolidated Group for the tax year in question realizes a net section
1231 gain, the tax benefit attributable to the  Overnite Consolidated Group's
net section 1231 loss shall be determined and allocated at the applicable rate
of tax for items of section 1231 gain income for such year. Where the Overnite
Consolidated Group realizes a net section 1231 loss and the Combined
Consolidated Group also realizes a net section 1231 loss for the tax year in
question:

          (i) The  Overnite Consolidated Group's net section 1231 loss shall be
multiplied by a ratio the numerator of which is the Combined Consolidated
Group's net section 1231 loss and the denominator of which is the sum of the net
section 1231 losses of the  Overnite Consolidated Group and those UPC Divisions
realizing net section 1231 

                                      I-3
<PAGE>
 
losses.

          (ii) The tax benefit attributable to the Overnite Consolidated Group's
net section 1231 loss shall be determined and allocated in an amount equal to
the sum of (x) the tax benefit of the product determined in clause (i) above,
calculated at the applicable rate of tax for items of section 1231 loss for such
year, and (y) the tax benefit of the difference between the Overnite
Consolidated Group's net section 1231 loss and the product determined in clause
(i) above, calculated at the applicable rate of tax for items of section 1231
gain for such year.

     (2) Notwithstanding the foregoing, to the extent that the Combined
Consolidated Group realizes a net section 1231 gain which is subject to the loss
recapture rules of section 1231 (c) of the Code, the additional tax associated
with the section 1231 loss recapture amount shall be borne by the members of the
Combined Consolidated Group which generated such net section 1231 losses during
the applicable look-back period. The net section 1231 losses which were
generated during the applicable look-back period and are the subject of loss
recapture in a post-1984 period shall be accounted for on a first-in, first-out
basis for purposes of sourcing the applicable period or periods to which such
loss recapture applies. To the extent that the loss recapture amount is sourced
from a year during the look-back period in which more than one Division had net
section 1231 losses, the  Overnite Consolidated Group shall be allocated a pro-
rata share of such loss recapture amount determined by multiplying the sourced
loss recapture amount of the Combined Consolidated Group for the period in
question by a ratio the numerator of which is the Overnite Consolidated Group's
net section 1231 loss for the period and the denominator of which is the sum of
the numerator and the net section 1231 losses of the 

                                      I-4
<PAGE>
 
UPC Divisions having net section 1231 losses for such period.

     d. Charitable Contribution Deductions. The  Overnite Consolidated Group
        ----------------------------------                                  
shall be allocated a charitable contribution deduction under section 170 of the
Code in an amount equal to the deduction realized by the Combined Consolidated
Group multiplied by a ratio the numerator of which is the charitable
contributions of the  Overnite Consolidated Group and the denominator of which
is the sum of the numerator and the charitable contributions of the UPC
Consolidated Group for such period. To the extent that the Combined Consolidated
Group is limited on the amount of its consolidated charitable contribution
deduction in any period, the  Overnite Consolidated Group shall be allocated any
tax benefit attributable to the excess charitable contributions when and if the
Combined Consolidated Group realizes such benefit in a subsequent period as
determined (on a first-in, first-out basis) by applying the foregoing allocation
principles in such subsequent period.

     e. Dividends-Received Deduction. To the extent that the  Overnite
        ----------------------------                                  
Consolidated Group has received dividends qualifying for a dividends-received
deduction under sections 243, 244, or 245 of the Code and the Combined
Consolidated Group's dividends-received deduction is not limited, the  Overnite
Consolidated Group shall be allocated the full allowable deduction (as limited
by subsection 246(c) or section 246A of the Code) based on the dividends it so
receives.  If the Combined Consolidated Group's dividends-received deduction is
limited in any tax period pursuant to a provision of the Code other than
subsection 246(c) or section 246A, the dividends received deduction allocated to
the Overnite Consolidated Group shall be limited to an amount equal to the
allowable dividends-received deduction of the Combined Consolidated Group
multiplied by a ratio 

                                      I-5
<PAGE>
 
the numerator of which is the sum of qualifying dividends received by the
Overnite Consolidated Group and the denominator of which is the sum of the
numerator and the qualifying dividends received by the UPC Consolidated Group.

     f. Alternative Minimum Tax (AMT) and Minimum Tax Credit (AMT Credit).
        ----------------------------------------------------------------- 
     (1) AMT. If the Combined Consolidated Group incurs an AMT liability under
         ---                                                                  
section 55 of the Code, the  Overnite Consolidated Group shall be allocated a
pro rata share of the excess of AMT over the regular tax liability (the "AMT
Increment") for the Combined Consolidated Group determined by multiplying the
Combined Consolidated Group's AMT Increment by a ratio the numerator of which is
the Overnite Consolidated Group's AMT Increment computed on a stand-alone basis
and the denominator of which is the sum of such numerator and the AMT Increments
of each UPC Division (using zero for any UPC Division which would have no AMT
Increment) computed on a stand-alone basis.

     (2) AMT Credit. To the extent that the Combined Consolidated Group utilizes
         ----------                                                             
an AMT Credit (including an AMT Credit attributable to a Fuel Credit carryover)
under section 53 of the Code against its regular tax liability for post-1987
periods, the applicable period to source such AMT Credit shall be determined on
a first-in, first-out basis. The Overnite Consolidated Group shall be allocated
a pro rata share of  such AMT Credit utilized by the Combined Consolidated Group
which is attributable to each sourcing period, determined by multiplying such
AMT Credit by a ratio the numerator of which is the  Overnite Consolidated
Group's AMT Increment (as determined under subsection (1) above)   for the
applicable sourcing period and the denominator of which is the sum of such
numerator and the AMT Increment of each UPC Division (as determined 

                                      I-6
<PAGE>
 
under subsection (1) above, increased by any Fuel Credit carryover attributable
to that UPC Division) for such applicable sourcing period. Notwithstanding the
foregoing, the Overnite Consolidated Group shall not be allocated the benefit
from any AMT Credits which are attributable to any period ending prior to
January 1, 1998.

     g. Credit for Producing Fuel from a Nonconventional Source (Fuel Credit).
        --------------------------------------------------------------------  
To the extent that the Combined Consolidated Group utilizes a Fuel Credit under
section 29 of the Code (other than AMT Credit which is attributable to a Fuel
Credit carryover, which shall be allocated under paragraph f above), the UPC
Consolidated Group shall be allocated all of such credit.

     h. Investment Tax Credit (ITC) and Investment Tax Credit Recapture (ITC
        --------------------------------------------------------------------
Recapture).
- ---------- 

     (1 ) ITC.  To the extent that the  Overnite Consolidated Group has
          ---                                                          
generated ITC (under former section 38 of the Internal Revenue Code of 1954, as
amended) on qualified property, and to the extent that the Combined Consolidated
Group is not limited in its utilization of such ITC, whether attributable to the
current period or by way of a carryback or carryforward, the  Overnite
Consolidated Group shall be allocated its full ITC based on its separate
qualified property. If the Combined Consolidated Group does not fully utilize
its ITC for any period, the  Overnite Consolidated Group shall be allocated its
pro rata share of the Combined Consolidated Group's ITC benefit for such period
determined by multiplying such benefit by a ratio the numerator of which is the
ITC generated by the  Overnite Consolidated Group for the period and the
denominator of which is the sum of the numerator and the ITC generated by all
UPC Divisions for the period. The  Overnite Consolidated Group shall be
allocated any tax benefit attributable 

                                      I-7
<PAGE>
 
to ITC carryovers when and if the Combined Consolidated Group realizes such
benefit in a subsequent period as determined (on a first-in, first-out basis) by
applying the foregoing allocation principles in such subsequent period.

     (2) ITC Recapture. To the extent that qualified property with respect to
         -------------                                                       
which the Overnite Consolidated Group has been allocated an ITC benefit is
prematurely disposed of (other than in connection with a deemed sale under the
Purchase Agreement pursuant to an election under Section 338(h)(10) of the Code)
thereby triggering ITC Recapture under section 47 of the Code, such ITC
Recapture shall be fully allocated to the  Overnite Consolidated Group in the
period in which such disposition occurs.

     i.  Credit for Increasing Research Activities (R&D Credit). To the extent
         ------------------------------------------------------               
that the Overnite Consolidated Group has an increase in its qualified research
expenses over its base period research expenses (the "Excess R&D Amount") as
defined in section 41 of the Code, and to the extent that the Combined
Consolidated Group utilizes an R&D Credit for such period, the  Overnite
Consolidated Group shall be allocated a pro rata share of the R&D Credit
utilized by the Combined Consolidated Group, based on a ratio the numerator of
which is the  Overnite Consolidated Group's Excess R&D Amount computed on a
stand-alone basis for the period and the denominator of which is the sum of the
numerator and the Excess R&D Amounts of each UPC Division having an Excess R&D
Amount computed on a stand-alone basis for the same period.

     j. Targeted Jobs Credit. To the extent that the Combined Consolidated Group
        --------------------                                                    
utilizes a targeted jobs credit within the meaning of section 51 of the Code,
the  Overnite Consolidated Group shall be allocated a pro rata share of such
credit determined by multiplying such credit by a ratio the numerator of which
is the  Overnite Consolidated 

                                      I-8
<PAGE>
 
Group's allowable targeted jobs credit computed on a stand-alone basis and the
denominator of which is the sum of the numerator and the allowable targeted jobs
credits of each UPC Division computed on a stand-alone basis.

     k. Credit for Federal Tax on Gasoline and Special Fuels. To the extent that
        ----------------------------------------------------                    
the Combined Consolidated Group utilizes a credit for federal tax on gasoline
and special fuels under section 34 of the Code, such credit shall be allocated
to the Division which generated it.

     1. Enhanced Oil Recovery Credit (EOR Credit). To the extent that the
        -----------------------------------------                        
Combined Consolidated Group generated  EOR Credits (within the meaning of
section 43 of the Code), whether attributable to the current period or by way of
a carryback or carryforward, the UPC  Consolidated Group shall be allocated all
of such EOR Credit.

     m. Foreign Tax Credits. The  Overnite Consolidated Group shall be allocated
        -------------------                                                     
the benefit of any foreign tax credits (under section 27 of the Code) realized
by the Combined Consolidated Group which are attributable to foreign taxes paid
by members of the Overnite Consolidated Group. If the Combined Consolidated
Group's utilization of foreign tax credits is limited in any tax period pursuant
to a provision of the Code, the Overnite Consolidated Group shall be allocated a
pro rata share of the foreign tax credit in an amount equal to the Combined
Consolidated Group's utilized foreign tax credit multiplied by a ratio the
numerator of which is the foreign tax credit of the  Overnite Consolidated Group
for such period and the denominator of which is the sum of the numerator and the
foreign tax credits of each UPC Division for such period. The tax benefit of any
unused foreign tax credit of the  Overnite Consolidated Group shall be allocated
when and if the Combined Consolidated Group realizes such benefit in a

                                      I-9
<PAGE>
 
subsequent period as determined (on a first-in, first-out basis) by applying the
foregoing allocation principles in such subsequent period.

     n. Interest on Tax Deficiencies and Refund Claims. To the extent that the
        ----------------------------------------------                        
allocated tax liability of the  Overnite Consolidated Group is increased, or its
allocated benefit is reduced, for any period, interest expense at the applicable
underpayment rates under section 6621 of the Code (or such higher interest rate
as is chargeable by the relevant taxing authority) for the periods in question
shall be allocated to the  Overnite Consolidated Group. To the extent that the
allocated tax liability of the  Overnite Consolidated Group is reduced, or  its
allocated benefit is increased, for any period, interest income at the
applicable overpayment rates under section 6621 of the Code (or such lower
interest rate as is payable by the relevant taxing authority) for the periods in
question shall be allocated to the  Overnite Consolidated Group.

     o. Penalties; Additions to Tax. Penalties and additions to tax assessed
        ---------------------------                                         
against the Combined Consolidated Group arising from Items allocated to (or tax
deficiencies, tax adjustments, or other matters related to) the  Overnite
Consolidated Group shall be directly allocated to the  Overnite Consolidated
Group. If penalties or additions to tax assessed against the Combined
Consolidated Group arise from Items allocated to (or tax deficiencies, tax
adjustments, or other matters related to) both the UPC Consolidated Group and
the  Overnite Consolidated Group, the  Overnite Consolidated Group shall be
allocated the amount of penalties or additions to tax which would have been
assessed against the Overnite Consolidated Group on a stand-alone basis.
Notwithstanding the foregoing, if the amount of penalties or additions to tax
assessed is limited because the Overnite Consolidated Group is included in the
Combined Consolidated Group, the 

                                      I-10
<PAGE>
 
Overnite Consolidated Group shall be allocated a pro rata share of the penalties
or additions to tax actually assessed determined by multiplying the amount of
such penalties or additions to tax by a ratio, the numerator of which is the
amount of penalties or additions to tax which would have been assessed against
the Overnite Consolidated Group on a stand-alone basis and the denominator of
which is the sum of the numerator and the amount of penalties or additions to
tax which would have been assessed against UPC on a stand-alone basis. Interest
on penalties and additions to tax shall be allocated to the party which is
allocated the penalties or additions to tax to which such interest relates.

     p. Unspecified Items. To the extent that an Item arises during a tax period
        -----------------                                                       
with respect to the  Overnite Consolidated Group that is included in the
Combined Consolidated Group's Federal Income Tax return but limited by reason of
a certain Code provision, regulation, ruling, or case law, and the allocation
provisions of this Appendix I do not specifically address the proration of such
Item, then the Parties shall attempt to agree on an equitable proration formula
within a reasonable period of notice of such issue. In the event no agreement is
reached, UPC shall apply the following principles in resolving such dispute:

     (i) The consolidated tax cost or benefit of an unspecified Item should be
allocated in proportion to the relative contribution of such unspecified Item by
the UPC Divisions and the  Overnite Consolidated Group.

     (ii) The amount of the allocation should be based on the actual
consolidated tax cost or benefit associated with such Item, rather than any
hypothetical costs or benefits 

                                      I-11
<PAGE>
 
which would arise if both the UPC Consolidated Group and the Overnite
Consolidated Group had filed separate returns on a stand-alone basis.

     (iii) The proration formula selected to allocate the tax cost or benefit
associated with such Item should be determined in a manner consistent with the
allocation procedures adopted herein for that specified Item most similar to the
unspecified Item in dispute. Failing resolution of the dispute on such basis, a
proration formula should be adopted which results in an equitable allocation of
the consolidated Item after taking into account the basis for the limitation
associated with the particular Code provision, regulation, ruling, or case law
dealing specifically with such unspecified Item.

                                  -----------

                                 ALLOCATION OF
                              UNITARY INCOME TAX
                            LIABILITIES AND BENEFITS

     Pursuant to Section 3.2 of this  Agreement, the  Overnite Consolidated
Group, or any member thereof, shall be allocated a pro rata share of any Unitary
Income Tax cost or benefit, including interest and penalties (either as
originally reported or as adjusted upon audit, amended return, or ultimate
settlement, or otherwise), arising by reason of its activities' being included
in a Unitary Income Tax return with activities of the UPC Consolidated Group or
any member thereof. In order to ascertain the  Overnite Consolidated Group's
allocated tax cost or benefit of such Unitary Income Tax Return in a particular
jurisdiction for a particular tax period, the following determinations and
allocation principles shall apply, subject to Section 3.2(c):

     Step 1. A hypothetical stand-alone Unitary Income Tax liability or benefit
     ------                                                                    
before application of NOLs and before credits ("Stand-alone Liability or
Benefit") for each Division in the Unitary Group shall be determined and
allocated to each Division. Divisions reporting a loss shall receive a benefit.
In the computation of each Division's Stand-alone Liability or Benefit, the
principles set forth in Section 3.1 and Appendix I of this Agreement with
respect to the computation and allocation of Federal Income Tax liability shall
be applied to the extent not inconsistent with Step 2 below, and all
limitations, modifications, allocation and apportionment methods, and elections
utilized 

                                      II-1
<PAGE>
 
in the Unitary Income Tax return as filed or adjusted shall govern the
computation of Divisions' Stand-alone Liability or Benefit.

     Step 2. The total of the Divisions' Stand-alone Liabilities (reduced by
     ------                                                                 
Stand-alone Benefits) as calculated in Step 1 shall be subtracted from the total
actual Unitary Income Tax liability before credits. The difference shall be
allocated to increase or reduce the Stand-alone Liability or Stand-alone Benefit
of each Division in an amount determined by multiplying such difference by a
ratio the numerator of which is the absolute value of such Division's Stand-
alone Liability or Benefit and the denominator of which is the sum of the
absolute values of each Division's Stand-alone Liability or Benefit.
Notwithstanding the foregoing, the portion of such difference which does not
exceed any NOL of the Unitary Group for the period (and the benefit, when
realized, of the NOL carryover or carryback associated with such portion) shall
be allocated to those Divisions which have a Stand-alone Benefit in an amount
determined by multiplying such portion by a ratio the numerator of which is such
Division's Stand-alone Benefit and the denominator of which is the sum of each
Division's Stand-alone Benefits. The benefit of any other NOL carryovers or
Carrybacks shall be allocated when realized based upon the ratio described in
the second sentence of this paragraph using Stand-alone Liabilities and Benefits
attributable to the period in which such NOL was generated.

     Step 3. Credits shall be allocated when realized to the Division which
     ------                                                                
generated the credits.

Miscellaneous Services of at least the same nature and quality as the similar

          -----

option to terminate this Agreement as to one or more of the particular
Miscellaneous Services by providing UPC with sixty (60) days' written notice

any time by providing UPC with written notice. If Overnite elects to terminate
Videoconferencing Equipment and Services prior to the end of the current lease
between UPC and Overnite for the Videoconferncing Equipment and Services,
Overnite agrees to pay remaining outstanding lease payments on the
Videoconferencing Equipment. Upon payment of such sums, all title to the
Videoconferencing Equipment shall pass to Overnite. UPC agrees to assist

          --------------------                                                  
in the first month after termination of this Agreement (or any extension
thereof), UPC shall submit to Overnite an invoice containing the estimated
charges for the Miscellaneous Services for the then current month and containing
a detailed statement, for the prior month, of all of the charges for
Miscellaneous Services.  Overnite shall remit payment in full for the estimated
charges, reflecting any adjustments for prior months' charges, by wire transfer
of immediately available funds to an account designated by UPC, on or prior to
the later of: (a) five (5) business days after receipt of such invoices, or (b)
the end of the then current month.  Overnite shall notify UPC of any dispute as
to an invoiced amount and the basis therefor.  In the event of a dispute as to
the invoiced amount, Overnite shall pay all undisputed amounts but shall be
entitled to withhold amounts in dispute. In the event of such a dispute, the
parties agree to provide each other with records and information relating to
such dispute and, without limiting their rights and remedies, to negotiate in
good faith to attempt to resolve such dispute.

          Any late payment shall be subject to any costs of collection

paid. UPC shall not commence suit on collection of late payment prior to
providing seven (7) days notice of its intent to commence suit to Overnite.

     6.   Multi-Century Compliance.  UPC represents that it is taking all
          ------------------------                                       
reasonable steps in an effort to make each item of hardware, software and
firmware created, modified, upgraded, revised, developed, or delivered
hereunder, or equipment and products containing such hardware, software or
firmware, accurately process date data (including without limitation
calculating, comparing and sequencing), within, from, into and between centuries
(including without limitation the twentieth and twenty-first centuries),
including leap year calculations.  UPC does not, by this Section, warrant that
each item of hardware, software and firmware created, modified, upgraded,
revised, developed, or delivered hereunder, or equipment and products containing
such hardware, software or firmware are Year 2000 compliant.

a party's business and which is not a matter of public record or generally known
to the public,

lists; bills; ideas; concepts; financial information; plans, practices, and
procedures; agreements, documents, or instruments involving the party; and any
information or materials deemed or designated as confidential or proprietary by
the party. Each party agrees that during and after the term of this Agreement
(or any extension thereof), unless specifically authorized by the other party in
a prior writing, it shall not, directly or indirectly, disclose the other
party's Confidential Information to any person or entity, or use the other
party's Confidential Information for its benefit. In the event that a party is
requested or required to disclose the other party's Confidential Information in
connection with any legal proceeding, interrogatory, subpoena, civil
investigative demand, or similar process, that party will promptly notify the
other party of the request or requirement so that the other party may seek an
appropriate protective order. If, in the absence of a protective order, a party,
on the advice of counsel, is compelled by any tribunal to disclose the other
party's Confidential Information, that party shall use its best

                                     - 8 -
<PAGE>
 
efforts to obtain an order or other assurance that confidential treatment will
be accorded to such Confidential Information required to be disclosed. Promptly

materials in its possession or control that contain, embody, or reflect the
other party's Confidential Information.

     8.   Assignment.  Neither party shall assign or transfer any of its rights
          -----------                                                          
or obligations under this Agreement except with the prior written consent of the
other party, which consent may be withheld by such other party in its sole
discretion.  This Agreement shall be binding upon and shall inure to the benefit
of the parties and their successors and permitted assigns. Notwithstanding any
other provision in this Agreement, UPC shall not be prohibited from selling or
divesting itself of UPT in any manner prior to the expiration of this Agreement,
provided that, in such event, this Agreement, and all rights and obligations
hereunder be assigned to and assumed by UPT and its affiliates.     

     9.  Liability and Indemnification. Except as provided specifically in the 
         -----------------------------            
Agreement, UPC shall have no liability under this Agreement for damage or loss
of any type suffered by Overnite or its subsidiaries or any third party as a
result of 

                                     - 9 -
<PAGE>
 
the performance or non-performance of the services provided under this
Agreement. Each party shall indemnify, defend and hold the other party harmless
from and against all damages, losses and out-of-pocket expenses (including fees
and disbursements of counsel) caused by or arising out of any willful breach or
gross negligence by such indemnifying party in the performance or non-
performance of any obligation or agreement contained herein or by the willful
misconduct of such indemnifying party. In the event of a claim against UPC by a
third party, Overnite shall indemnify, defend and hold UPC harmless from and
against all damages, losses and out-of-pocket expenses (including fees and
disbursements of counsel) caused by or arising out the performance or non-
performance of any obligation or agreement contained herein except where caused
by the willful breach, negligence, or willful misconduct of UPC. Notwithstanding
any other provision of this Agreement, UPC shall have no liability for the acts
or omissions of any third party (other than a subsidiary of UPC) that provides
services under this Agreement so long as UPC has not been grossly negligent in
the selection of such third party. In the event Overnite believes UPC is not
performing its obligations under this Agreement in accordance with the standards
agreed upon by the parties, Overnite shall so

                                     - 10 -
<PAGE>
 
notify UPC.  UPC agrees to cooperate with Overnite to address such performance
issues and to bring UPC's performance into conformance with such standards.

     10.  Licenses and Permits.  Overnite, at Overnite's sole expense, shall be
          --------------------                                                 
responsible for obtaining all necessary software licenses and/or permits
required for the performance of Miscellaneous Services as a result of the
Offering and Acquisition and OTC's and Overnite's corporate status.  Failure by
Overnite to obtain any necessary licenses and/or permits will not give rise to a
cause of action under this Agreement against UPC (including contract, tort or
warranty).  UPC will cooperate in good faith to assist Overnite with securing
all necessary licenses and/or permits.

assigned to OTC or Overnite.  UPC will encourage Development Staff Personnel to
remain at such present positions and will work with Overnite to establish
incentive programs to retain the employees, provided, however, that no

Agreement in accordance with the standards agreed upon by the parties, Overnite

performance issues and to bring UPC's performance into conformance with such
standards.

Trust") will be transferred to a trust established by Overnite for the Overnite
Plan;

     NOW, THEREFORE, in consideration of the mutual promises and covenants
herein contained, the parties hereto agrees as follows:

     1. ESTABLISHMENT OF TRUST. Overnite shall establish a trust, in form and

     2. ASSET TRANSFER. As soon as practicable after the IPO, UPC shall cause

a value equal to the total fair market value of the assets of the Overnite Plan
as of June 30, 1998, and (b) adjusted to reflect earnings or losses on such
assets through the date of the transfer of the assets.  UPC shall cause the

such records and information as may be necessary or appropriate to carry out
their respective obligations under this Agreement.  UPC, OTC, and Overnite agree
to file all documents required as a result of the Sale and the IPO, including
but not limited to any notices of "reportable events" required by Section
4043(b) of the Employee Retirement Income Security Act of 1974, as amended.

duties under this Agreement without first obtaining the prior written consent of
the other parties, which may be withheld by such other parties in their absolute
discretion. This Agreement shall be binding upon and inure to the benefit of the
parties hereto and their successors and permitted assigns.
