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) 

 
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

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

     OTC; and any real property and buildings held under lease by the Company,
     OHI and OTC are held by them under valid, subsisting and enforceable leases

     material adverse effect on the Company, OHI and OTC, taken as a whole,
     except as described the Prospectus.
 
          (z)  The Company, OHI and OTC maintain a system of internal accounting
     controls sufficient to provide reasonable assurance that (i) transactions
     are executed in accordance with management's general or specific
     authorizations; (ii) transactions are recorded as necessary to permit
     preparation of financial statements in conformity with generally accepted
     accounting principles and to maintain asset accountability; (iii)

     access to assets is permitted only in accordance with management's general
     or specific authorization; and (iv) the recorded accountability for assets

     appropriate action is taken with respect to any differences.

solely for the purpose of covering over-allotments made in connection with the
offering of the U.S. Firm Shares. If any Additional Shares are to be purchased,
each U.S. Underwriter agrees, severally and not jointly, to purchase the number
of Additional Shares (subject to such adjustments to eliminate fractional shares
as the U.S. Representatives may determine) that bears the same proportion to the
total number of Additional Shares to be purchased as the number of U.S. Firm
Shares set forth in Schedule I hereto opposite the name of such Underwriter
bears to the total number of U.S. Firm Shares.

          Each of the Company and UPC hereby agrees that, without the prior
written consent of Morgan Stanley & Co. Incorporated on behalf of the
Underwriters, it will not, during the period ending 180 days after the date of
the Prospectus, except with respect to employee stock option plans in effect as
of the date of this Agreement, (i) offer, pledge, sell, contract to sell, sell
any option or 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 (ii) 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 (i) or (ii) 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 the Shares to be sold hereunder.

          4.  Terms of Public Offering.  The Company is advised by you that the
Underwriters propose to make a public offering of their respective portions of
the Shares as soon after the Registration Statement and this Agreement have
become effective as in your judgment is advisable.  The Company is further
advised by you that the Shares are to be offered to the public initially at
U.S.$_____ a share (the "PUBLIC OFFERING PRICE") and to certain dealers selected
by you at a price that represents a concession not in excess of U.S.$____ a
share under the Public Offering Price, and that any Underwriter may allow, and
such dealers may reallow, a concession, not in excess of U.S.$____ a share, to
any Underwriter or to certain other dealers.

          6.  Conditions to the Underwriters' Obligations. The obligations of
the Company to sell the Shares to the Underwriters and the several obligations

     each case from that set forth in the Prospectus (exclusive of any
     amendments or supplements thereto subsequent to the date of this Agreement)
     that, in your judgment, is material and adverse and that makes it, in your
     judgment, impracticable to market the Shares on the terms and in the manner
     contemplated in the Prospectus.

          (b)  The Underwriters shall have received on the Closing Date:

               (i)  certificates, dated the Closing Date and signed by (x) an

          true and correct as of the Closing Date and that the Company, OHI and
          OTC have complied with all of the agreements and satisfied all of the
          conditions on their part to be performed or satisfied hereunder on or

     dated the Closing Date, to the effect that:

          obligations under, this Agreement will not contravene any provision of
          applicable law or the certificate of incorporation or by-laws of the
          Company, OHI or OTC or, to such counsel's knowledge, any agreement or
          other instrument binding upon the Company, OHI or OTC that is material
          to the Company, OHI and OTC and its subsidiaries, taken as a whole,
          or, to the best of such counsel's knowledge, any judgment, order or
          decree of any governmental body, agency or court having jurisdiction
          over the Company, OHI or OTC, and no consent, approval, authorization
          or order of, or qualification with, any governmental body or agency is
          required for the performance by the Company, OHI or OTC of its

          jurisdictions in connection with the offer and sale of the Shares by
          the U.S. Underwriters and International Underwriters;

                                       15

 
               (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

 
          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

          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

          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.

     U.S. Representatives, dated the Closing Date, to the effect that:

          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.

     opinion of Richards Layton & Finger, Delaware counsel to the Company, dated
     the Closing Date, to the effect that:

          7.  Covenants of the Company and UPC.  In further consideration of the

     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

     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

     so amended or supplemented will not, in 

                                       21

 
     the light of the circumstances when the Prospectus is delivered to a

     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

     Registration Statement, any preliminary prospectus, the Prospectus and

     fees and expenses of any consultants engaged in connection with the road

     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

 
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

 
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

 
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

 
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

 
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

 
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,


                              ____________________________
