                        TO BE HELD ON NOVEMBER   , 1997
    
 
TO THE SHAREHOLDERS OF MAIL BOXES ETC.:
 
   
    A Special Meeting of Shareholders of Mail Boxes Etc. (the "Company" or
"MBE") will be held at the Company's offices at 6060 Cornerstone Court West, San
Diego, California 92121 on          , November   , 1997, at 9:00 a.m., Pacific
Standard Time (together with any adjournment or postponement thereof, the
"Special Meeting"), for the following purposes:
    
 
   
1.  To consider and vote upon a proposal to approve the principal terms of the
    Agreement and Plan of Merger, dated May 22, 1997 as amended as of October 9,
    1997 (the "Merger Agreement"), relating to the merger of a wholly owned
    subsidiary of U.S. Office Products Company ("USOP") with and into MBE. Under
    the original terms of the Merger Agreement, the outstanding shares of common
    stock, no par value per share, of MBE, are to be converted into shares of
    common stock, $.001 par value per share, of USOP, subject to certain
    conditions and adjustments as set forth in the Merger Agreement. On October
    7, 1997, USOP announced a three-for-two stock split in the form of a stock
    dividend (the "stock split") payable on November 6, 1997 to record holders
    as of October 23, 1997. To give effect to the stock split, USOP and MBE
    amended the Merger Agreement as of October 9, 1997 all as more fully set
    forth in the accompanying Proxy Statement/Prospectus and in the Merger
    Agreement, a copy of which is included as Appendix I to the Proxy
    Statement/Prospectus; and
    
 
2.  To transact such other business as may properly come before the Special
    Meeting or any adjournment or postponement thereof.
 
   
    Only shareholders of record at the close of business on September 30, 1997
are entitled to notice of and to vote at the Special Meeting.
    
 
                                          By Order of the MBE Board of
                                          Directors,

                                          Vice President, General Counsel and
                                          Secretary

                                OCTOBER   , 1997
    
 
TO THE SHAREHOLDERS OF MAIL BOXES ETC.:
 
   
    You are cordially invited to attend a Special Meeting of Shareholders of
Mail Boxes Etc. (the "Company" or "MBE") on          , November   , 1997, at
9:00 a.m., Pacific Standard Time, at the Company's offices at 6060 Cornerstone
Court West, San Diego, California 92121 (together with any adjournment or
postponement thereof, the "Special Meeting").
    
 
   
    As described in the enclosed Proxy Statement/Prospectus, at the Special
Meeting you will be asked to consider and vote upon a proposal to approve the
principal terms of the merger of a newly created, wholly owned subsidiary of
U.S. Office Products Company ("USOP") with and into MBE (the "Merger") as
provided in the Agreement and Plan of Merger, dated as of May 22, 1997 as
amended as of October 9, 1997 (the "Merger Agreement"). Upon completion of the
Merger, MBE will become a wholly owned subsidiary of USOP. Under the original
terms of the Merger Agreement, each outstanding share of common stock of MBE was
to be converted into one share of common stock of USOP, subject to certain
conditions and adjustments as set forth in the Merger Agreement. On October 7,
1997, USOP announced a three-for-two stock split in the form of a stock dividend
(the "stock split") payable on November 6, 1997, to record holders as of October
23, 1997. To give effect to the stock split, USOP and MBE amended the Merger
Agreement as of October 9, 1997 so that each outstanding share of common stock
of MBE will be converted into 1.5 shares of common stock of USOP, subject to
certain conditions and adjustments as set forth in the Merger Agreement. The
Merger Agreement and the proposed Merger are discussed in more detail in the
accompanying Proxy Statement/Prospectus and its appendices (the "Proxy
Statement/ Prospectus").
    
 
    In light of the proposed Merger, the Company has not scheduled and, if the
Merger is approved by shareholders and consummated, does not anticipate holding,
its Annual Meeting of Shareholders.
 
    A summary of certain provisions of Chapter 13 of the California General
Corporation Law pertaining to the rights of dissenting shareholders in
connection with the proposed Merger is included in the Proxy
Statement/Prospectus in the section entitled "The Merger--Dissenters' Rights of
Appraisal." The complete text of Chapter 13 of the California General
Corporation Law is included as Appendix III to the Proxy Statement/Prospectus.
 
    The Merger is intended to be a tax-free reorganization for federal income
tax purposes. See "The Merger--Certain Federal Income Tax Consequences" in the
accompanying Proxy Statement/Prospectus.
 
    IN UNANIMOUSLY APPROVING THE MERGER AGREEMENT, YOUR BOARD OF DIRECTORS HAS
DETERMINED THAT THE MERGER IS IN THE BEST INTERESTS OF MBE AND ALL OF ITS
SHAREHOLDERS AND RECOMMENDS THAT THE SHAREHOLDERS OF MBE VOTE TO APPROVE THE
PRINCIPAL TERMS OF THE MERGER AND THE TRANSACTIONS IT CONTEMPLATES.
 
    The Merger Agreement and financial and other information concerning the
businesses of MBE and USOP are included in the Proxy Statement/Prospectus and
other documents filed by MBE and USOP with the Securities and Exchange
Commission. Please review the Proxy Statement/Prospectus carefully.
 
    The affirmative vote of the holders of a majority of the outstanding shares
of MBE common stock is required to approve the principal terms of the Merger.
Therefore, failure to return the proxy card will have the same effect as a vote
against the Merger. Accordingly, we urge you to complete, sign and date the
enclosed proxy card and return it in the enclosed return envelope, whether or
not you plan to attend the Special Meeting. Your vote is important.
 
                                        Sincerely,
 
                                        Anthony W. DeSio
 
                                        VICE CHAIRMAN OF THE BOARD AND CHIEF

                                PROXY STATEMENT
                            ------------------------
 
   
                          U.S. OFFICE PRODUCTS COMPANY
                                   PROSPECTUS
                    UP TO 19,530,457 SHARES OF COMMON STOCK
    
 
   
    This Proxy Statement/Prospectus relates to the proposed merger (the
"Merger") of Mail Boxes Etc., a California corporation (the "Company" or "MBE"),
and Santa Fe Acquisition Corp. ("Sub"), a newly created, wholly owned subsidiary
of U.S. Office Products Company, a Delaware corporation ("USOP" or "U.S. Office
Products"), pursuant to an Agreement and Plan of Merger, dated as of May 22,
1997 (the "Merger Agreement"), by and among USOP, Sub and the Company. As of
October 9, 1997, USOP, MBE and Sub amended the Merger Agreement (the amended
Merger Agreement is hereafter referred to as the "Merger Agreement"). On October
7, 1997, USOP announced a three-for-two stock split in the form of a stock
dividend (the "stock split") payable on November 6, 1997 to record holders as of
October 23, 1997. The October 9, 1997 amendment to the Merger Agreement included
changes made to take account of the stock split. The information in this Proxy
Statement/Prospectus describes the terms of the Merger on a post-stock split
basis except where otherwise indicated.
    
 
   
    In the Merger, USOP will exchange 1.5 shares of its common stock, par value
$.001 per share ("USOP Common Stock"), for each share of the Company's common
stock, no par value per share (the "MBE Common Stock" or the "Company Common
Stock"), if the average of the daily closing prices (as reported on the Nasdaq
National Market) of a share of USOP Common Stock during the Averaging Period (as
defined below) is between $15.33 and $19.33. Prior to the declaration of the
stock split and the amendment of the Merger Agreement, each share of Company
Common Stock was to be exchanged for 1 share of USOP Common Stock, subject to
adjustment if the Average Price of USOP Common Stock (as defined below) was less
than $23.00 or more than $29.00. The revised terms--adjusting the Exchange Ratio
to 1.5 shares of USOP Common Stock for each share of Company Common Stock,
subject to adjustment if the Average Price of USOP Common Stock is less than
$15.33 or more than $19.33--reflect the impact of the stock split and preserve
the economic terms of the Merger, as originally agreed to by USOP and MBE prior
to the declaration of the stock split.
    
 
   
    The Averaging Period is the period consisting of the 20 trading days ending
either two business days before the date of the Company's special meeting (the
"Special Meeting") of shareholders (if the closing of the Merger takes place
within five business days of the Special Meeting) or two business days before
the closing date of the Merger (if the closing takes place more than five
business days after the Special Meeting). The term "Average Price of USOP Common
Stock" means the average of the daily closing prices (as reported on the Nasdaq
National Market) of USOP Common Stock during the Averaging Period, with the
closing prices on all days prior to November 7, 1997 (the ex-dividend date)
being divided by 1.5 to give effect to the stock split. Prior to November 7,
1997, the closing prices of USOP Common Stock will be reported on the Nasdaq
National Market without giving effect to the stock split. To convert the daily
closing prices of USOP Common Stock on all days prior to November 7, 1997 into a
post-split equivalent price, the closing price on each such day will be divided
by 1.5 and the resulting adjusted closing price will be used to determine the
Average Price of USOP Common Stock.
    
 
   
    If the Average Price of USOP Common Stock is more than $19.33, the number of
shares of USOP Common Stock for which each share of MBE Common Stock will be
exchanged in the Merger (the "Exchange Ratio") will be adjusted as described
below. If the Average Price of USOP Common Stock is less than $15.33, the
Exchange Ratio may be adjusted as described below. Because the Averaging Period
for determining the Average Price of USOP Common Stock may extend until as late
as two business days before the closing of the Merger, the Exchange Ratio will
not be known with certainty until as late as such time. Therefore, at the time
they vote, MBE shareholders will not know the number of shares of USOP Common
Stock that they will receive in the Merger. The following toll-free number is
available for MBE shareholders to obtain a daily closing price for the USOP
Common Stock: 800/874-1667. As described herein, the maximum value of the USOP
Common Stock (based upon the Average Price of USOP
    
<PAGE>
   
Common Stock) to be received by MBE shareholders in the Merger is capped at
$29.00 per share of MBE Common Stock. However, there is no minimum value (based
upon the Average Price of USOP Common Stock) for the USOP Common Stock to be
received by shareholders in the Merger, and such value could be less than $23.00
per share of MBE Common Stock. See "Risk Factors--Special Considerations with
Respect to the Merger--Risks Associated with Exchange Ratio," "--Merger Approval
Confers Discretion on Company Board to Terminate or Proceed with Merger if
Average Price of USOP Common Stock is Below $15.33," "The Mail Boxes Etc.
Special Meeting--Matters to be Considered" and "The Merger Agreement--Conversion
of Shares."
    
 
   
    Based upon the number of outstanding shares of USOP Common Stock and MBE
Common Stock as of September 30, 1997, the record date for the Special Meeting
(the "Record Date"), and assuming the Exchange Ratio is equal to 1.5, up to
18,886,582 shares of USOP Common Stock will be issued to the Company's
shareholders in the Merger (assuming currently exercisable options to purchase
1,786,129 shares of MBE Common Stock are fully exercised) representing
approximately 17.0% of the shares of USOP Common Stock that would be outstanding
immediately following the closing of the Merger. On October 6, 1997, the last
reported sale price of the MBE Common Stock on the Nasdaq National Market was
$28.25 per share, and the last reported sale price of the USOP Common Stock on
the Nasdaq National Market on the same day was $35.125 per share (which price
does not reflect the stock split).
    
 
    The Merger is subject to a number of conditions. Among these conditions are
(i) the approval of the principal terms of the Merger by the shareholders of
MBE, (ii) the continuing accuracy, generally as of the closing date of the
Merger, of the representations and warranties made by USOP and MBE in the Merger
Agreement, (iii) the receipt of all required governmental approvals, and (iv)
the receipt of certain advice regarding the tax and accounting consequences of
the Merger. In addition, if holders of more than five percent of the outstanding
shares of MBE Common Stock vote against approval of the principal terms of the
Merger, USOP may, in its discretion, elect to terminate the Merger Agreement.
 
   
    U.S. Office Products has filed a Registration Statement on Form S-4 (such
registration statement and all exhibits and amendments thereto are referred to
herein as the "Registration Statement") pursuant to the Securities Act of 1933,
as amended (the "Securities Act"), covering the issuance of up to 19,530,457
shares of USOP Common Stock, in connection with the Merger. This Proxy
Statement/Prospectus also constitutes a prospectus of USOP comprising a part of
the Registration Statement.
    
 
    Certain major shareholders of MBE beneficially owning, as of the Record
Date, an aggregate of approximately 34% of the outstanding shares of MBE Common
Stock have executed and delivered agreements and irrevocable proxies to USOP
obligating these shareholders, among other things, to vote their shares of MBE
Common Stock in favor of the Merger (hereinafter, the "Voting Agreements"). See
"The Merger--Voting Agreements."
 
    All information contained in this Proxy Statement/Prospectus relating to
USOP has been supplied by USOP, and all information relating to the Company has
been supplied by the Company.
 
    SEE "RISK FACTORS" BEGINNING ON PAGE 16 FOR CERTAIN INFORMATION THAT SHOULD
BE CONSIDERED BY MBE SHAREHOLDERS.
 
    THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES
AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE
ACCURACY OR ADEQUACY OF THIS PROXY STATEMENT/PROSPECTUS. ANY REPRESENTATION TO
THE CONTRARY IS A CRIMINAL OFFENSE.
 
   
    THIS PROXY STATEMENT/PROSPECTUS AND THE ACCOMPANYING FORM OF PROXY ARE FIRST
BEING MAILED TO SHAREHOLDERS OF THE COMPANY ON OR ABOUT OCTOBER   , 1997. A
SHAREHOLDER WHO HAS GIVEN A PROXY MAY REVOKE IT AT ANY TIME BEFORE IT IS
EXERCISED.

THE SPECIAL MEETING
 
    TIME, PLACE AND DATE

offices at 6060 Cornerstone Court West, San Diego, California 92121 on
November   , 1997, at 9:00 a.m., Pacific Standard Time. See "The Mail Boxes Etc.
Special Meeting--General."
    
 
    PURPOSES OF THE SPECIAL MEETING
 
    At the Special Meeting, holders of MBE Common Stock will consider and vote
upon a proposal to approve the principal terms of the Merger. Upon completion of
the Merger, MBE will become a wholly owned subsidiary of USOP. Shareholders will
also consider and vote upon any other matter that may properly come before the
Special Meeting. See "The Mail Boxes Etc. Special Meeting--Matters to be
Considered."
 
    VOTE REQUIRED; RECORD DATE
 
    The approval of the principal terms of the Merger will require the
affirmative vote of the holders of a majority of the outstanding shares of MBE
Common Stock entitled to vote on such matter. Only holders of MBE Common Stock
as of the close of business on the Record Date will be entitled to notice of,
and to vote at, the Special Meeting. See "The Mail Boxes Etc. Special Meeting."
 
    RECOMMENDATION OF THE COMPANY'S BOARD OF DIRECTORS
 
    The Board of Directors of the Company (the "Company Board") believes that
the terms of the Merger are fair to, and in the best interests of, the Company
and its shareholders. By a unanimous vote of the Company Board at a meeting held
on May 21, 1997, the Company Board approved the Merger Agreement and recommends
a vote FOR approval of the principal terms of the Merger.
 
    SECURITY OWNERSHIP OF MANAGEMENT
 
   
    As of the Record Date, directors and executive officers of MBE were
beneficial owners of approximately 19% of the outstanding shares of MBE Common
Stock. As of the Record Date, directors and executive officers of USOP and their
affiliates were not beneficial owners of any of the outstanding shares of MBE
Common Stock.
    
 
    THE VOTING AGREEMENTS
 
    Certain major shareholders of MBE beneficially owning, as of the Record
Date, an aggregate of approximately 34% of the outstanding shares of MBE Common
Stock have executed and delivered the Voting Agreements to USOP obligating these
shareholders, among other things, to vote their shares of MBE Common Stock in
favor of the Merger. These agreements terminate if the Merger Agreement is
terminated. See "The Merger--Conflicts of Interest" and "--Voting Agreements."
 
    OPINION OF MBE'S FINANCIAL ADVISOR
 
    MBE retained ABN AMRO Chicago Corporation ("AACC") to act as its financial
advisor in connection with a possible transaction to enhance shareholder value.
As part of this engagement, MBE requested that AACC render its opinion as to the
fairness to MBE's shareholders of the Exchange Ratio to be received in the
Merger.
 
    As part of its evaluation of the proposed terms of the Merger, AACC rendered
an opinion that, as of May 22, 1997, and subject to certain assumptions, factors
and limitations set forth in its written opinion as
 
                                       4
<PAGE>
described below, the Exchange Ratio to be received by MBE shareholders is fair
to such shareholders from a financial point of view. See "The Merger--Opinion of
Financial Advisor."
 
   
    THE FULL TEXT OF THE WRITTEN OPINION OF AACC, DATED MAY 22, 1997, WHICH SETS
FORTH THE ASSUMPTIONS MADE, MATTERS CONSIDERED AND LIMITATIONS ON THE REVIEW
UNDERTAKEN IN CONNECTION WITH THE OPINION, IS ATTACHED AS APPENDIX II TO THIS
PROXY STATEMENT/PROSPECTUS AND SHOULD BE READ IN ITS ENTIRETY. AACC'S OPINION
DOES NOT REFLECT THE STOCK SPLIT ANNOUNCED BY USOP ON OCTOBER 7, 1997. AACC'S
OPINION WAS PREPARED FOR THE COMPANY BOARD AND ADDRESSES ONLY THE FAIRNESS OF
THE EXCHANGE RATIO TO THE HOLDERS OF MBE COMMON STOCK FROM A FINANCIAL POINT OF
VIEW. THE AACC OPINION DOES NOT CONSTITUTE A RECOMMENDATION TO ANY SHAREHOLDER
AS TO HOW SUCH SHAREHOLDER SHOULD VOTE WITH RESPECT TO THE PROPOSED MERGER AND
DOES NOT CONSTITUTE AN OPINION AS TO WHAT THE VALUE OF USOP COMMON STOCK
ACTUALLY WILL BE WHEN ISSUED TO MBE SHAREHOLDERS IN THE MERGER. THE SUMMARY OF
THE OPINION OF AACC SET FORTH IN THIS PROXY STATEMENT/ PROSPECTUS IS QUALIFIED
IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF SUCH OPINION.
    
 
THE MERGER
 
    GENERAL
 
    The Merger Agreement contemplates the merger of Sub, a wholly owned and
newly created subsidiary of USOP, with and into the Company whereby the Company
will survive the Merger. Once the Merger is completed, the Company will become a
wholly owned subsidiary of USOP.
 
   
    Under the terms of the Merger Agreement, USOP will exchange 1.5 shares of
USOP Common Stock for each share of MBE Common Stock in the Merger if the
Average Price of USOP Common Stock is between $15.33 and $19.33. If the Average
Price of USOP Common Stock is more than $19.33, the Company's shareholders will
receive for each share of MBE Common Stock that number of shares of USOP Common
Stock equal to 1.5 times the quotient of $19.33 divided by the Average Price of
USOP Common Stock. If the Average Price of USOP Common Stock is less than $15.33
and if MBE elects to terminate the Merger Agreement, USOP has the option, but
not the obligation, to adjust the Exchange Ratio to be equal to 1.5 times the
quotient of $15.33 divided by the Average Price of USOP Common Stock. If USOP
adjusts the Exchange Ratio as described, MBE must accept the adjustment and,
assuming all other conditions are satisfied or waived, proceed with the Merger.
If the Average Price of USOP Common Stock is less than $15.33 and MBE does not
elect to terminate the Merger Agreement, the Exchange Ratio will not change.
Shareholders should note that, under the terms of the Merger Agreement, the
maximum value (based on the Average Price of USOP Common Stock) of the USOP
Common Stock to be received by MBE shareholders in the Merger is capped at
$29.00 per share of MBE Common Stock, while there is no minimum value of such
stock to be received in the Merger. Because the Averaging Period for determining
the Average Price of USOP Common stock may extend until as late as two business
days before the closing of the Merger, the Exchange Ratio will not be known with
certainty until as late as such time. Therefore, at the time they vote, MBE
shareholders will not know the number of shares of USOP Common Stock that they
will receive in the Merger. The following toll-free number is available for MBE
shareholders to obtain a daily closing price for the USOP Common Stock:
800/874-1667. See "Risk Factors--Special Considerations with Respect to the
Merger--Risks Associated with Exchange Ratio," "--Merger Approval Confers
Discretion on Company Board to Terminate or Proceed with Merger if Average Price
of USOP Common Stock is Below $15.33" and "The Mail Boxes Etc. Special Meeting--
Matters to be Considered." Each of the shareholders of MBE Common Stock who
would be entitled to receive a fractional share of USOP Common Stock upon
surrender of such shareholder's shares of MBE Common Stock will receive, in lieu
thereof, cash in an amount equal to the value of such fractional share. See "The
Merger Agreement--General" and "--Conversion of Shares."
    
 
    The Merger will become effective on the date when the parties file with the
California Secretary of State all of the documents required to be filed by the
California General Corporation Law (the "CGCL") (such documents, the "Merger
Documents"), or at such other time as Sub and MBE agree should be
 
                                       5
<PAGE>
specified in the Merger Documents (the date and time of such filing, or such
later date or time as may be set forth in the filing, will be referred to as the
"Effective Time"). Assuming all conditions to the Merger contained in the Merger
Agreement are satisfied or waived prior thereto, it is currently anticipated
that the Effective Time will occur as soon as practicable following the MBE
Special Meeting.
 
    CONFLICTS OF INTEREST
 
    In considering the recommendation of the Company Board with respect to the
Merger, shareholders should be aware that certain members of the Company's
management and the Company Board have interests in the Merger that are in
addition to their interests in the Merger as shareholders of the Company
generally. These interests arise from, among other things, certain employee
benefit plans, indemnification arrangements and other matters that USOP will
assume or has agreed to provide after the Merger. See "The Merger--Conflicts of
Interest."
 
    GOVERNMENTAL AND REGULATORY APPROVAL
 
    Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended
(the "HSR Act"), and the rules promulgated thereunder by the Federal Trade
Commission (the "FTC"), the Merger may not be completed until notifications have
been given and certain information has been furnished to the FTC and the
Antitrust Division of the U.S. Department of Justice (the "Antitrust Division")
and specified waiting period requirements have been satisfied. USOP and MBE
filed notification and report forms under the HSR Act with the FTC and the
Antitrust Division on June 20, 1997. The FTC and the Antitrust Division granted
early termination of the HSR Act waiting period on July 3, 1997. Thus, the
waiting period requirements of the HSR Act have been satisfied. Nevertheless, at
any time before or after consummation of the Merger, the FTC, the Antitrust
Division or state attorneys' general could take such action under the antitrust
laws as they deem necessary or desirable in the public interest, including
seeking to enjoin the consummation of the Merger. Private parties may also seek
to take legal action under the antitrust laws under certain circumstances.
 
    Based on the information available to them, USOP and MBE believe that the
Merger can be effected in compliance with federal and state antitrust laws.
However, there can be no assurance that a challenge to the completion of the
Merger on antitrust grounds will not be made or that, if such challenge were
made, USOP and MBE would prevail or would not be required to accept certain
conditions, including the divestitures of certain assets, in order to complete
the Merger.
 
    ACCOUNTING TREATMENT
 
    The Merger is intended to qualify as a pooling-of-interests for accounting
purposes. Under this method of accounting, following completion of the Merger,
the financial conditions, results of operations and cash flows of USOP and MBE
will be reflected for accounting purposes as if MBE had always been a wholly
owned subsidiary of USOP. USOP has been advised by its independent accountants
that they believe the Merger will qualify as a pooling-of-interests under
generally accepted accounting principles. MBE has been advised by its
independent accountants that MBE meets the criteria for a pooling-of-interests.
USOP's obligation to complete the Merger is conditioned on, among other things,
(i) the receipt by USOP and MBE, at the Effective Time, of written confirmation
from their respective independent accountants of the advice described above, and
(ii) no events having occurred which would establish with reasonable certainty
that the Merger could not be treated as a pooling-of-interests.
 
    FEDERAL INCOME TAX CONSEQUENCES
 
    The Merger is intended to be a tax-free reorganization in which no gain or
loss will be recognized by USOP or MBE and no gain or loss will be recognized by
MBE shareholders, except with respect to cash received in lieu of fractional
shares. MBE has received an opinion of its counsel, O'Melveny & Myers LLP,
 
                                       6
<PAGE>
to the effect that the Merger will constitute a tax-free reorganization within
the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended
(the "Code"). For a summary of the substance of such opinion, see "The
Merger--Federal Income Tax Consequences."
 
    CONDITIONS TO THE MERGER
 
    The obligations of USOP and MBE to consummate the Merger are subject to
various conditions. Among these conditions are (i) the approval of the principal
terms of the Merger by the shareholders of MBE, (ii) the continuing accuracy,
generally as of the closing date of the Merger, of the representations and
warranties made by USOP and MBE in the Merger Agreement, (iii) the receipt of
all required governmental approvals, and (iv) confirmation of the accountants'
advice and receipt of the tax opinion described above. See "The Merger
Agreement--Conditions."
 
    TERMINATION
 
   
    The Merger Agreement may be terminated at any time prior to the Effective
Time (a) by mutual written consent of USOP and MBE; (b) by MBE or USOP if the
Merger has not occurred by November 30, 1997 (unless the failure to consummate
the Merger is the result of a breach of a covenant or a willful and material
breach of any representation or warranty set forth in the Merger Agreement by
the party seeking to terminate the Merger Agreement); (c) if the Average Price
of USOP Common Stock is less than $15.33 and USOP determines not to adjust the
Exchange Ratio to be equal to the 1.5 times the quotient of $15.33 divided by
the Average Price of USOP Common Stock after receipt of MBE's notice that it
intends to terminate the Merger Agreement; or (d) upon the occurrence of certain
other events described below. See "The Merger Agreement--Termination."
    
 
    If the Merger Agreement is terminated pursuant to specified termination
provisions in the Merger Agreement, MBE will be required to pay a cash
termination fee and certain other cash amounts to USOP. Such cash termination
fee and other cash amounts will be at least equal to $4,623,262 and may be
significantly higher under certain circumstances. See "The Merger
Agreement--Termination."
 
   
    DISCRETION OF COMPANY BOARD TO TERMINATE OR PROCEED WITH MERGER IF AVERAGE
     PRICE OF USOP COMMON STOCK IS BELOW $15.33
    
 
   
    If the Average Price of USOP Common Stock is below $15.33, the Company Board
may elect to (i) terminate the Merger Agreement, in which event the Merger would
be terminated unless USOP were to agree to adjust the Exchange Ratio to provide
the MBE shareholders with at least $23.00 in value (based on the Average Price
of USOP Common Stock) per share of MBE Common Stock, or (ii) proceed with the
Merger with an Exchange Ratio equal to 1.5, without any adjustment. Subject to
compliance with its fiduciary duties to shareholders, the Company Board does not
currently plan to submit to a further shareholder vote the Company Board's
decision whether to terminate or proceed with the Merger if the Average Price of
USOP Common Stock is below $15.33. See "Risk Factors--Special Considerations
with Respect to the Merger--Merger Approval Confers Discretion on Company Board
to Terminate or Proceed with Merger if Average Price of USOP Common Stock is
Below $15.33" and "The Mail Boxes Etc. Special Meeting--Matters to be
Considered."
    
 
    DISSENTERS' RIGHTS
 
    Under the CGCL, shareholders of record of MBE who do not wish to accept
shares of USOP in the Merger will have the right to have the fair value of their
MBE shares appraised by judicial determination and paid to them in cash only if
demands for payment are duly filed with respect to five percent or more of the
outstanding shares of MBE Common Stock. In order to perfect such dissenters'
rights, holders of MBE Common Stock must comply with certain procedural
requirements, including filing written notice with MBE not later than the date
of the Special Meeting of an intention to dissent and demand payment of the
 
                                       7
<PAGE>
fair value of their shares, voting against approval of the principal terms of
the Merger and making a written demand for payment and depositing the
certificates representing such shares within 30 days after notice is given by
USOP and MBE of the results of the vote at the Special Meeting. See "The
Merger--Dissenters' Rights of Appraisal" and Appendix III.
 
    FEDERAL SECURITIES LAW CONSEQUENCES
 
    This Proxy Statement/Prospectus, unless appropriately amended or
supplemented, does not cover any resales by MBE shareholders of any shares of
USOP Common Stock that they receive in the Merger, and no person is authorized
to make any use of this Proxy Statement/Prospectus in connection with any such
resale.
 
    All shares of USOP Common Stock received by MBE shareholders in the Merger
will be freely transferable, except that persons who are deemed to be
"affiliates" (as such term is defined for purposes of the pooling-of-interests
requirements and the Securities Act) of MBE prior to the Merger may resell
shares they receive only in transactions permitted by the resale provisions of
Rule 145 promulgated under the Securities Act, or as otherwise permitted under
the Securities Act. Persons who may be deemed to be affiliates of MBE generally
include individuals or entities who or that control, are controlled by, or are
under common control with, MBE and may include certain officers, directors and
principal shareholders of MBE. In addition, except for certain permitted DE
MINIMIS sales (subject to compliance with federal securities laws), such
affiliates will not be permitted to sell shares they receive in the Merger until
USOP has released results of operations that reflect the combined post-Merger
operations of USOP and MBE for a minimum of 30 days.
 
    LISTING
 
    It is a condition to the Merger that the shares of USOP Common Stock to be
issued in the Merger be authorized for quotation and trading on the Nasdaq
National Market.
 
    COMPARATIVE RIGHTS OF STOCKHOLDERS
 
    The rights of shareholders of MBE currently are governed by the CGCL, as
well as the Restated Articles of Incorporation of MBE (the "MBE Charter") and
the Restated Bylaws of MBE (the "MBE Bylaws"). Upon consummation of the Merger,
shareholders of MBE will become stockholders of USOP, and their rights as
stockholders of USOP will be governed by the Delaware General Corporation Law
(the "DGCL"), the Amended and Restated Certificate of Incorporation of USOP (the
"USOP Charter") and the Amended and Restated Bylaws of USOP (the "USOP Bylaws").
For a discussion of various differences between the rights of shareholders of
MBE and the rights of stockholders of USOP, see "Comparative Rights of
Stockholders of U.S. Office Products and Mail Boxes Etc."
 
    CERTAIN OTHER AGREEMENTS
 
    Each of the affiliates of MBE has agreed not to transfer or otherwise
dispose of or reduce such affiliate's risk relating to (i) any shares of MBE
Common Stock within 30 days prior to the Effective Time, and (ii) any shares of
USOP Common Stock until USOP has released results of operations that reflect the
combined post-Merger operations of USOP and MBE for a minimum of 30 days, except
for certain DE MINIMIS transactions as permitted under the affiliate agreements.
In addition, each of the affiliates has agreed to certain federal securities law
restrictions on the resale of USOP Common Stock. See "The Merger--Federal
Securities Law Consequences." The restrictions on resale are intended to
preserve the characterization of the Merger for federal income tax purposes as a
tax-free reorganization, to comply with the requirements for
pooling-of-interests accounting treatment and to comply with restrictions on the
resale of securities imposed by the federal securities laws.

    accounted for under the purchase method is included from the dates of their

    show the pro forma income before extraordinary item and book value
    attributable to each share of MBE Common Stock that will be exchanged for
    USOP Common Stock in the Merger. Because it is assumed that each share of
    MBE Common Stock will be exchanged for one share of USOP Common Stock, the

                                  RISK FACTORS
 
    THE FOLLOWING RISK FACTORS, IN ADDITION TO THE OTHER INFORMATION CONTAINED
OR INCORPORATED BY REFERENCE IN THIS PROXY STATEMENT/PROSPECTUS, SHOULD BE
CONSIDERED BY HOLDERS OF MBE COMMON STOCK IN EVALUATING WHETHER TO APPROVE THE
MERGER AND THEREBY BECOME HOLDERS OF USOP COMMON STOCK. THESE FACTORS SHOULD BE
CONSIDERED IN CONJUNCTION WITH THE OTHER INFORMATION INCLUDED OR INCORPORATED BY
REFERENCE INTO THIS PROXY STATEMENT/PROSPECTUS.
 
    SPECIAL CONSIDERATIONS WITH RESPECT TO U.S. OFFICE PRODUCTS COMPANY.
Relevant risk factors to the operation of USOP's business include the following:
 
    DEPENDENCE UPON ACQUISITIONS FOR FUTURE GROWTH
 
    USOP's increase in revenues and the markets it serves since its formation
has depended upon the acquisition of additional businesses offering a broad
array of office and educational products and business services. There can be no
assurance that definitive agreements for additional acquisitions will be
executed or that additional acquisitions will be completed. In addition, there
can be no assurance that USOP's management and financial controls, personnel,
computer systems and other corporate support systems will be adequate to manage
the continuing increase in the size and scope of its operations and acquisition
activity.
 
    USOP depends on acquisitions and organic growth to increase its earnings.
There can be no assurance that it will complete acquisitions in a manner that
coincides with the end of its fiscal quarters. The failure to complete
acquisitions on a timely basis could have a material adverse effect on USOP's
quarterly results. Likewise, delays in implementing planned integration
strategies and activities also could adversely affect its quarterly earnings.
 
    In addition, there can be no assurance that future acquisitions will occur
at the same pace or be available to USOP on favorable terms, if at all. If USOP
is unable to use USOP Common Stock as consideration in acquisitions, for
example, because it believes that the market price of USOP Common Stock is too
low or because the owners of potential acquisition targets conclude that the
market price of USOP Common Stock is too volatile, USOP would need to use cash
to make acquisitions and, therefore, would be unable to negotiate acquisitions
that it would account for under the pooling-of-interests method of accounting
(which is available only for all-stock acquisitions). This might adversely
affect the pace of USOP's acquisition program and the impact of acquisitions on
USOP's quarterly results. In addition, the consolidation of the domestic
contract stationer industry has reduced the number of larger companies available
for sale, which could lead to higher prices being paid for the acquisition of
the remaining domestic, independent companies.
 
    RISKS RELATED TO EXPANSION INTO NEW PRODUCT AND SERVICE AREAS AND TO
     ACQUISITIONS
 
    USOP has increased the range of products and services it offers through
acquisitions of companies offering products and services that are complementary
to the office supply services that USOP has offered since it began operations.
USOP's ability to manage an aggressive consolidation program in markets other
than the domestic contract stationer market has not yet been fully tested.
USOP's efforts to sell additional products and services to existing customers
are in their early stages and there can be no assurance that such efforts will
be successful. In addition, USOP expects that certain of its products and
services will not be easily cross-sold and may be marketed and sold
independently of other products and services.
 
    In addition, there can be no assurance that companies that have been
acquired or that may be acquired in the future will achieve sales and
profitability levels that justify the purchase prices paid by USOP. Acquisitions
may involve a number of special risks that could have a material adverse effect
on USOP's operations and financial performance, including adverse short-term
effects on its reported operating results; diversion of management's attention;
difficulties with the retention, hiring and training of key personnel; risks
associated with unanticipated problems or legal liabilities; and amortization of
 
                                       16
<PAGE>
acquired intangible assets. Finally, although USOP conducts due diligence and
generally requires representations, warranties and indemnifications from the
former owners of acquired companies, there can be no assurance that such owners
will have accurately represented the financial and operating conditions of their
companies. If an acquired company's financial or operating results were
misrepresented, the acquisition could have a material adverse effect on the
results of operations and financial condition of USOP.
 
    RISKS RELATED TO INTERNATIONAL EXPANSION
 
    As of September 3, 1997, USOP conducted international operations in New
Zealand, Australia, Canada and, through its 49% interest in Dudley Stationery
Limited ("Dudley"), in the United Kingdom. USOP's international operations have
grown substantially since USOP's inception. International revenues increased
from $197.3 million, or 11.7% of consolidated revenues, in fiscal 1996, to
$829.9 million, or 29.3% of consolidated revenues in fiscal 1997. USOP expects
to continue to focus significant attention and resources on international
expansion in the future and expects foreign sales to continue to represent a
significant portion of USOP's total sales. Expansion into international markets
involves additional risks relating to currency exchange rates; new and different
legal, regulatory and competitive requirements; difficulties in staffing and
managing foreign operations; different business lines; and other factors.
 
    RISKS RELATED TO INTEGRATION OF ACQUISITIONS AND LIMITED COMBINED OPERATING
     HISTORY
 
    USOP was founded in October 1994 and conducted no operations prior to the
acquisition of its founding companies in February 1995. From its initial public
offering through the end of its most recent fiscal year, USOP acquired 159
companies. Since the end of its 1997 fiscal year, USOP has continued to make
acquisitions. In most cases, the managers of the acquired companies have
continued to operate their companies after being acquired by USOP. There can be
no assurance that USOP will be able to integrate all of these companies within
its operations without substantial costs, delays or other problems. In addition,
there can be no assurance that USOP's executive management group can continue to
oversee USOP and effectively implement its operating or growth strategies in
each of the markets that it serves. There also can be no assurance that the
rapid pace of acquisitions will not adversely affect USOP's continuing efforts
to integrate acquisitions and manage those acquisitions profitably.
 
    DEPENDENCE UPON IMPLEMENTATION AND OPERATION OF SYSTEMS
 
    USOP believes that the successful operation of the businesses that it has
acquired and intends to acquire depends in part on the implementation of
computerized inventory management and order processing systems and warehouse
management and distribution systems. USOP may experience delays, complications
or expenses in implementing, integrating and operating its various systems, any
of which could have a material adverse effect on USOP's results of operations
and financial condition. In addition, interruptions or disruptions in systems
operations could adversely affect the financial results of particular locations.
Finally, USOP expects that its operating and technology systems will require
modification, improvement or replacement as USOP expands or as new technologies
make these systems obsolete. Such modifications, improvements or replacements
may require substantial expenditures to design and implement and may require
interruptions in operations during periods of implementation, any of which could
have a material adverse effect on USOP's results of operations and financial
condition.
 
    SUBSTANTIAL COMPETITION AND INDUSTRY CONSOLIDATION
 
    USOP operates in a highly competitive environment. In the markets in which
it operates, USOP generally competes with a large number of smaller, independent
companies, many of which are well-established in their markets. In addition, in
the contract stationer market, USOP currently competes with five large office
products companies, each of which has significant financial resources. Several
of its large competitors operate in many of its geographic and product markets,
and other competitors may choose to enter USOP's geographic and product markets
in the future. In addition, as a result of this competition,
 
                                       17
<PAGE>
USOP may lose customers or have difficulty acquiring new customers. As a result
of competitive pressures on the pricing of products, USOP's revenues or margins
may decline.
 
    USOP faces significant competition to acquire additional businesses as the
office products industry undergoes continuing consolidation. Significant
competition exists, or is expected to develop, in the other markets that USOP
serves or is planning to enter as consolidation occurs (or accelerates) in those
markets. A number of USOP's major competitors are actively pursuing acquisitions
outside of the United States. These companies, or other large companies, may
compete with USOP for acquisitions in markets other than the market for office
products. Such competition could lead to higher prices being paid for acquired
companies.
 
    In response to industry and market changes, including industry consolidation
and the continued volatility in the market prices of shares of common stock of
companies in the industry, USOP considers, from time to time, additional
strategies to enhance stockholder value in light of such changes. These include,
among others, strategic alliances and joint ventures; spin-offs; purchase, sale,
or merger transactions with other large companies; a recapitalization of USOP;
and other similar transactions. In considering any of these strategies, USOP
evaluates the consequences of such strategies including, among other things, the
leverage that would result from such a transaction, the tax effects of the
transaction, and the accounting consequences of the transaction, including
whether the transaction would result in the need for USOP to restate its
financial statements to account for prior transactions under the purchase rather
than the pooling-of-interests method or would eliminate USOP's ability to use
the pooling-of-interest method of accounting to account for acquisitions in the
future. In addition, such strategies could have various other significant
consequences, including changes in the management, control or operational or
acquisition strategies of USOP. There can be no assurance that any one of these
strategies will be undertaken, or that, if undertaken, any such strategy will be
completed successfully.
 
    CONSIDERATION FOR OPERATING COMPANIES EXCEEDS ASSET VALUE
 
    The purchase prices of USOP's acquisitions have not been established by
independent appraisals, but generally have been determined through arm's length
negotiations between USOP's management and representatives of such companies.
The consideration paid for each such company has been based primarily on the
value of such company as a going concern and not on the value of the acquired
assets. Valuations of these companies determined solely by appraisals of the
acquired assets would have been less than the consideration paid for the
companies. No assurance can be given that the future performance of such
companies will be commensurate with the consideration paid. Moreover, USOP has
incurred and expects to continue to incur significant amortization charges
resulting from consideration paid in excess of the fair value of the net assets
of the companies acquired in business combinations accounted for under the
purchase method of accounting.
 
    QUARTERLY FLUCTUATIONS IN OPERATING RESULTS
 
    USOP's business is subject to seasonal influences. USOP's revenues and
profitability in its core office products business have been lower in the first
two quarters of its fiscal year, primarily due to the lower level of business
activity in North America during the summer months. The seasonality of the core
office products business, however, is expected to be impacted by the seasonality
of its other operations, which have been expanding through acquisitions. For
example, the revenues and profitability of USOP's school supplies and school
furniture business have been higher during USOP's first and second quarters and
significantly lower in its third and fourth quarters, and the revenues and
profitability of USOP's operations in New Zealand and Australia have generally
been higher in USOP's third quarter. As USOP's mix of business evolves through
future acquisitions, these seasonal fluctuations may continue to change.
 
    Quarterly results also may be materially affected by the timing of
acquisitions, the timing and magnitude of costs related to such acquisitions,
variations in the prices paid by USOP for the products it sells, the mix of
products sold, general economic conditions and the retroactive restatement in
accordance with generally accepted accounting principles of USOP's consolidated
financial statements for acquisitions
 
                                       18
<PAGE>
accounted for under the pooling-of-interests method. Moreover, the operating
margins of companies acquired by USOP may differ substantially from those of
USOP, which could contribute to the further fluctuation in its quarterly
operating results. Therefore, results for any quarter are not necessarily
indicative of the results that USOP may achieve for any subsequent fiscal
quarter or for a full fiscal year. Fluctuations caused by variations in
quarterly operating results may have a material adverse effect on the market
price of USOP Common Stock.
 
    VOLATILITY OF STOCK PRICE
 
    The market price of USOP Common Stock is subject to significant
fluctuations. These fluctuations can be caused by variations in stock market
conditions, changes in financial estimates by securities analysts or failures by
USOP or its competitors to meet such estimates, quarterly operating results,
announcements by USOP or its competitors, general conditions in the office
products and services industry and other factors. Since the beginning of fiscal
1997 through September 3, 1997, USOP Common Stock has traded in the range of
$20.00 to $45.50 per share. The stock market in recent years has experienced
extreme price and volume fluctuations that often have been unrelated or
disproportionate to the operating performance of publicly traded companies.
These broad fluctuations may have a material adverse effect on the market price
of USOP Common Stock.
 
    NEED FOR ADDITIONAL FINANCING TO CONTINUE ACQUISITION STRATEGY
 
    USOP expects that it will continue to finance acquisitions in the United
States by using cash as well as shares of USOP Common Stock. In addition, USOP
expects that future acquisitions outside of the United States may be entirely or
substantially for cash consideration. In certain circumstances, USOP may be
unable to use stock as consideration for acquisitions. See "-- Dependence upon
Acquisitions for Future Growth." If it does not have sufficient cash resources
to pay the cash consideration for acquisitions, USOP may be unable to continue
the current pace of its aggressive acquisition program, which could have a
material adverse impact on it and the market price of USOP Common Stock.
 
    Assuming that the current pace of its acquisitions continues, USOP may need
debt or equity financing in order to continue its acquisition program. There can
be no assurance that it will be able to obtain such financing if and when it is
needed or that any such financing will be available on terms it deems
acceptable.
 
    RELIANCE ON KEY PERSONNEL
 
    USOP's operations depend on the continued efforts of Jonathan J. Ledecky,
its Chairman of the Board and Chief Executive Officer, its other executive
officers and the senior management of certain of its subsidiaries. Furthermore,
USOP's operations will likely depend on the senior management of certain of the
companies that may be acquired in the future.
 
    Although Mr. Ledecky devotes substantially all of his time and attention to
USOP's business, Mr. Ledecky is the Non-Executive Chairman of U.S.A. Floral
Products, Inc. ("USA Floral"), a company co-founded by Mr. Ledecky in April 1997
to create a national consolidator and operator of floral products distribution
businesses, and Chairman of Consolidation Capital Corporation ("CCC"), a company
founded by Mr. Ledecky in February 1997 to build consolidated enterprises
through the acquisition of businesses in a variety of fragmented industries,
other than the industries in which USOP is currently involved and certain other
industries. USA Floral has filed a registration statement under the Securities
Act to register 4.6 million shares for sale to the public at a disclosed
estimated price per share of between $10.00 and $12.00. Mr. Ledecky owns 1.1
million shares of the common stock of USA Floral. CCC has filed a registration
statement under the Securities Act to register 25 million shares for sale to the
public at a disclosed estimated price per share of $20.00. Mr. Ledecky owns
approximately 4.4 million shares of the common stock of CCC. CCC has stated that
it intends to hire an executive management team with acquisition experience.
 
                                       19
<PAGE>
    If Mr. Ledecky or any of the other people described above becomes unable to
continue in his or her present role, or if USOP is unable to attract and retain
other skilled employees, its business could be adversely affected. USOP
currently has key man life insurance covering Mr. Ledecky in the amount of $20
million, but it does not have and does not intend to obtain key man life
insurance covering any of its other executive officers or other members of
senior management of its subsidiaries.
 
    CONTROL BY MANAGEMENT AND STOCKHOLDERS
 
    As of September 3, 1997, officers and directors of USOP and its subsidiaries
beneficially owned approximately 26% of the outstanding shares of USOP Common
Stock. These stockholders acting together may be able to elect a sufficient
number of directors to control USOP's Board of Directors and to approve or
disapprove any matter submitted to a vote of stockholders.
 
    RISKS RELATED TO UNIONIZED EMPLOYEES
 
    A small number of USOP's employees are members of labor unions. If unionized
employees were to engage in a strike or other work stoppage, or if other
employees were to become unionized, USOP could experience a disruption of
operations or higher labor costs, which could have a material adverse effect on
operations.
 
    POTENTIAL EFFECT OF SHARES ELIGIBLE FOR FUTURE SALE ON PRICE OF USOP COMMON
     STOCK
 
   
    USOP has an aggressive acquisition program under which it has issued
approximately 48 million of its approximately 73 million outstanding shares as
of September 3, 1997. As of September 3, 1997, approximately 2.5 million of the
shares issued in acquisitions were subject to contractual restrictions on the
transfer thereof. The contractual restrictions expire at various times,
generally up to two years from the date of issuance of the shares. In addition,
as of September 3, 1997, approximately 500,000 of the 48 million shares of USOP
Common Stock issued in acquisitions were subject to restrictions on transfer
because they were issued in acquisitions accounted for under the
pooling-of-interests method of accounting. Under the pooling-of-interests method
of accounting, the affiliates of the acquired companies, which are, in most
cases, all of the stockholders of the companies acquired by USOP, must be free
to sell or otherwise transfer shares of USOP Common Stock received in the
acquisition, subject to their compliance with the federal securities laws, as
soon as USOP releases results of operations that reflect the combined
post-acquisition operations of USOP and the acquired company for a minimum of 30
days. The approximately 500,000 shares (750,000 shares after the stock split) of
USOP Common Stock will become freely transferable (subject to certain volume and
other restrictions of Rule 145(d) under the Securities Act) upon USOP's public
announcement of results of operations reflecting 30 days of combined
post-acquisition operations of it and the acquired companies. In addition, if
the Merger is completed at an Exchange Ratio of 1.5, approximately 7.6 million
shares (including approximately 1.6 million shares subject to currently
exercisable options) to be received by affiliates of MBE will become freely
transferable upon USOP's public announcement of results of operations reflecting
30 days of combined post-Merger operations. USOP expects to complete additional
acquisitions in the future that will be accounted for under the
pooling-of-interests method. If a significant number of shares of USOP Common
Stock are issued in acquisitions that are completed in close proximity to each
other, such shares will become freely tradeable at the same time. If a large
number of shares are sold in the market by stockholders (such as former
affiliates of MBE) as soon as their shares become freely transferable, the price
of shares of USOP Common Stock could be adversely affected.
    
 
    ANTI-TAKEOVER EFFECTS OF CERTAIN CHARTER PROVISIONS
 
    The Board of Directors of USOP has the authority to issue up to 500,000
shares of preferred stock and to determine the price, rights, preferences and
privileges of those shares without any further stockholder action. The rights of
the holders of USOP Common Stock will be subject to, and may be adversely
affected by, the rights of the holders of any shares of preferred stock that may
be issued in the
 
                                       20
<PAGE>
future. The issuance of preferred stock could have the effect of making it more
difficult for a third party to acquire a majority of the outstanding voting
stock of USOP.
 
    SPECIAL CONSIDERATIONS WITH RESPECT TO MAIL BOXES ETC.  Relevant risk
factors to the operation of the Company's business include the following:
 
    RECENT CHANGES TO SENIOR MANAGEMENT AND ASSOCIATED RISKS
 
    The operating results of any company are heavily dependent upon the efforts
and success of its senior management team. In the past 12 months, the Company's
senior management team has undergone major changes with the addition of a new
President and Chief Operating Officer and a number of other members of senior
management, some of whom have been with the Company for fewer than six months.
Moreover, the Company's Chief Executive Officer, who has led the Company from
its inception 17 years ago, is expected to retire shortly. The Company is
subject to certain risks associated with its new management structure,
including, among others, risks relating to employee and franchise relations,
managerial efficiency and effectiveness and overall familiarity with MBE's
business and operations.
 
    RELIANCE ON UNITED PARCEL SERVICE AND ASSOCIATED RISKS; RECENT WORK STOPPAGE
     AT UNITED PARCEL SERVICE
 
    The Company estimates that nearly 40% of the gross sales of a typical MBE
center in the United States are attributable to services provided by United
Parcel Service ("UPS"). In addition, the Company estimates that over 90% of
general ground shipping from MBE centers in the United States is done through
UPS. As such, UPS is a key vendor for the MBE network. If UPS were to raise its
prices to the MBE network or otherwise materially adversely change the terms on
which it does business with the MBE network, the revenues of the MBE network
could be materially and adversely affected. The Company's contract with UPS,
providing for the rates and other terms on which UPS provides services to the
Company's franchisees and their customers, has been terminable upon seven days'
notice by either party. This contract expired on May 10, 1997. Since then, the
companies have been operating under extensions of this contract. Negotiations
for a new contract are in progress.
 
    From August 4, 1997 through August 19, 1997 the International Brotherhood of
Teamsters was on strike against UPS. As a result, UPS effectively ceased
providing shipping services to the Company's franchisees for a period of 16
calendar days. The Company's franchisees used the services of alternative
carriers including Federal Express and the U.S. Postal Service, but such
alternative carriers did not, during this period, fully accommodate the
shipments that would have been handled by UPS in the absence of the strike. In
addition, the Company believes that during the strike many shipments were
deferred by customers. The strike had an adverse impact on the MBE franchisees
during this period and will, in turn, adversely affect MBE's revenue from
royalty and marketing fees with respect to the period of the strike. Utilizing
"worst case" assumptions, that is, that during the strike there was no revenue
from shipments ordinarily handled by UPS, no shipments were handled by
alternative carriers and no shipments were deferred for shipment following
termination of the strike, the Company estimates that its revenues for the
period of the strike would decrease by approximately $820,000 and the
corresponding reduction in net income for the month would be approximately
$300,000, or approximately $0.0245 per share. It is a condition to USOP's
obligation to effect the Merger that there not have occurred a material adverse
change in MBE's business, operations, financial condition or results of
operations between the date of the Merger Agreement and the proposed Closing
Date. Accordingly, if the UPS strike constituted such a material adverse change,
USOP would be entitled under the Merger Agreement not to effect the Merger.
 
   
    As of the Record Date, UPS owned approximately 16% of the outstanding shares
of MBE Common Stock. If the Merger is completed, UPS will own approximately 2.4%
of USOP Common Stock based upon the shares outstanding as of the Record Date.
    
 
                                       21
<PAGE>
    LACK OF CONTROL OVER FRANCHISES
 
    As is true of franchises generally, the Company is limited in the amount of
control it may exercise over its licensed franchisees. In the United States,
only one of the MBE centers is Company-owned; the remainder of the MBE centers
are owned and operated by franchisees licensed directly by MBE. Outside of the
United States, all of the MBE centers are owned and operated by MBE's master
licensees or franchisees licensed by MBE's master licensees. This lack of direct
control by MBE may limit MBE's ability to, among other things, launch "pilot" or
test programs, introduce new goods and services, establish system wide
purchasing programs and generally change the image or focus of the MBE system in
the future. The Company's inability to take any of such actions in the future
could have a material adverse effect on its business and results of operations.
 
    FLUCTUATIONS IN OPERATING RESULTS
 
    The Company's operating results are affected by a wide variety of factors
that could materially and adversely affect its revenues and profitability,
including factors pertaining to (i) customer demand; (ii) general economic
conditions in the retail industry and in countries in which the Company's
franchisees and master licensees do business; (iii) competition (see "--
Competition"); (iv) fluctuations in foreign currency exchange rates and the
possibility that one or more master licensees may experience high rates of
inflation or currency crises in their respective countries; (v) new product
development, such as increased research, development and marketing expenses
associated with new product introductions and risks associated with customer
acceptance (see also "-- Dependence upon Development of New Products and
Services" below); and (vi) sales and marketing risks, including the risk that
the Company will be unable to continue selling franchises at current or historic
levels.
 
    COMPETITION
 
    The businesses in which MBE operates are highly competitive. MBE experiences
competition from several sources. Direct competition comes from other national
chains and independents and from specialty service providers, such as copy
centers, quick print centers and office supply companies. There is also growing
competition from the United States Postal Service as it attempts to compete
against MBE centers with its postal service centers located in shopping centers
and other locations. MBE is attempting to respond to these competitive
challenges. However, there can be no assurance that the Company's efforts will
prove beneficial or that MBE ultimately will be able to compete effectively in
the markets in which it currently operates or in which it may operate in the
future. See "-- Dependence upon Development of New Products and Services."
 
    GOVERNMENTAL REGULATION
 
   
    The FTC has adopted a rule that requires franchisors to make certain
disclosures to prospective franchise owners prior to the offer or sale of
franchises. This rule requires, among other things, the disclosure of
information necessary for a prospective franchise owner to make an informed
decision as to whether to enter into a franchise relationship and requires
disclosure of the circumstances in which franchisors may make predictions on
future sales, income and profits. Failure to comply with this rule constitutes
an unfair or deceptive act or practice under the Federal Trade Commission Act
(the "FTC Act"). Violators of the rule are subject to civil penalty actions
brought by the FTC of up to $10,000 per violation. In addition, the FTC may
bring an action in federal or state court for damages on behalf of franchisees.
No assurance can be given that such a proceeding will not be commenced in the
future. Any such proceeding against the Company, were it to be commenced, could
result in significant expense to the Company and diversion of management's time
and effort, which could have a material adverse effect on the Company.
    
 
                                       22
<PAGE>
    Numerous states have adopted laws regulating franchise operations and the
franchisor-franchisee relationship, and similar legislation has been proposed in
the U.S. Congress and several other states. Existing state laws impose various
filing and disclosure requirements in connection with the offer and sale of
franchises and regulate the establishment and termination of, and provide
remedies respecting, franchise relationships. These laws generally apply to both
MBE's area and individual franchises. In addition, some states may bring either
civil or criminal proceedings against a franchisor for violations of state law.
The Florida Attorney General's Office investigated the Company's franchise
practices several years ago and has not formally closed the investigation. No
assurance can be given that other state proceedings will not be commenced in the
future. Any such proceeding against the Company, were it to be commenced, could
result in significant expense to the Company and diversion of management's time
and effort, which could have a material adverse effect on the Company.
 
    Violation of state franchise laws can also result in various remedies for
franchisees, including a right to rescind the franchise agreement and obtain
restitution of amounts paid and a right to sue for damages. As of the date
hereof, the Company is subject to pending actions brought by various of its
current and former franchisees alleging, among other things, violations by the
Company of state franchise laws. No assurance can be given that such actions
will not have a material adverse effect on the Company. See "-- Legal
Proceedings."
 
    LEGAL PROCEEDINGS
 
    As of the date hereof, MBE is subject to various pending lawsuits from its
individual franchisees and former employees and may in the future become subject
to lawsuits and claims in the course of its business. While MBE intends to
defend vigorously these actions, the Company is unable to make a meaningful
estimate of the amount or range of loss that could result from an unfavorable
outcome of all pending litigation, such as the impact of litigation or
settlement costs on MBE's results of operations for any particular period. No
assurance can be given that the pending litigation, or any future litigation to
which the Company may become subject, will not have a material adverse effect on
MBE's financial condition or liquidity. See -- "Governmental Regulation."
 
    DEPENDENCE UPON AND LIMITATIONS ON PROTECTION OF PROPRIETARY RIGHTS
 
    MBE believes that proprietary rights have been and will continue to be
important in enabling it to compete. MBE is the owner of federal and, where
appropriate, state registered trademarks and service marks, which include "Mail
Boxes Etc.", "Mail Boxes Etc. USA", "MBE", "Minute Mail", "The Post Office
Alternative", "MBE and Square Globe Design", "Money Back Express","Big or Small,
We Ship It All", "Making Business Easier", "TicketNet", "It's Not What We Do,
It's How We Do It" and "We're the Biggest Because We Do It Right." MBE has also
developed various symbols or icons representing MBE services and has obtained
copyright registration for many of those symbols. MBE has filed for registration
for the service mark "No Limit Shipping". MBE has also applied for registration
of one or more of its marks in foreign countries where it has expanded and plans
to expand. MBE plans to file for trademark protection for other marks if and
when they may be developed. However, no assurance can be given that MBE will
develop any new marks or that any of MBE's pending or future applications for
foreign or domestic trademark protection will ultimately be approved by the
applicable government authorities.
 
    MBE may be involved from time to time in litigation to determine the
enforceability, scope and validity of proprietary rights. Any such litigation
could result in substantial cost to MBE and diversion of effort by MBE's
management. No assurance can be given that any such litigation, if commenced,
would be resolved in a manner favorable to MBE or that MBE will otherwise be
successful in protecting or establishing the validity of proprietary rights.
 
    MBE is aware of a few limited geographic areas in which the use of the "Mail
Boxes Etc." name or variations thereof by others apparently predates MBE's
rights. No assurance can be given that such areas
 
                                       23
<PAGE>
will not be material to the future expansion of MBE's business. In Canada, where
there are approximately 185 MBE centers, the Canada Post Corporation ("CPC"), a
crown corporation of the Canadian government, has opposed MBE's trademark
filings since the original applications were filed in approximately 1987. CPC
has informed MBE that it believes that it has exclusive trademark rights to the
words "mail" and "post" under applicable Canadian law. In recent rulings, the
Canadian trademark office has denied several of MBE's trademark applications on
the basis of CPC's opposition thereto. MBE is currently in negotiations with CPC
regarding the use of MBE's trademarks in Canada. However, no assurance can be
given as to the ultimate outcome of these negotiations or as to MBE's ability
ultimately to obtain satisfactory trademark protection in Canada.
 
    DEPENDENCE UPON DEVELOPMENT OF NEW PRODUCTS AND SERVICES
 
    The Company believes that, in order to remain competitive in the business
services, communications and postal business sectors, it will be necessary to
successfully develop and introduce new products and services. In the past, the
Company has successfully developed and introduced a number of innovative
products and services, such as color copying, "No Limit Shipping" and its
national accounts program. However, there can be no assurance that the Company
will be able to develop or introduce successfully any new products or services
in the future. The Company's inability to develop and introduce new products and
services could cause the Company to lose market share and impair its
competitiveness, which would materially and adversely affect the Company's
operations and financial performance.
 
    DEPENDENCE UPON INTERNATIONAL EXPANSION AND DEVELOPMENT AND ASSOCIATED RISKS
 
    An integral part of the Company's future expansion plans includes continued
international expansion through the sale of new master licenses and by assisting
in the development of existing master licensees. As of September 3, 1997, there
were over 500 franchised MBE centers operating outside of the United States, and
master licenses had been sold to develop the MBE system in over 50 countries.
The international expansion of the MBE franchise system entails, in addition to
the risks described above, substantial risks relating to currency exchange
rates; new and different legal, regulatory and competitive requirements;
difficulties in attracting and supporting qualified entrepreneurs who can adapt
the MBE system to local markets and simultaneously build a franchise system;
risks that the master licensees in the various international markets could fail
in their performance and attract litigation from their franchisees or suppliers;
and other factors. There can be no assurance that the Company will be successful
in managing these risks or in achieving any desired international expansion of
the MBE franchise system.
 
    SPECIAL CONSIDERATIONS WITH RESPECT TO THE MERGER
 
    RISKS ASSOCIATED WITH EXCHANGE RATIO
 
   
    As described herein (see "The Merger Agreement -- Conversion of Shares"),
the number of shares of USOP Common Stock to be received by MBE shareholders
will be based upon the Average Price of USOP Common Stock over the Averaging
Period. The actual dollar value of USOP Common Stock to be received by MBE
shareholders as of the Effective Time of the Merger will depend upon the market
price of USOP Common Stock as of such time. Such market price may be less than
or greater than the Average Price of USOP Common Stock. The market prices of
USOP Common Stock and MBE Common Stock as of a recent date are set forth above
under the heading "Market Price Data." MBE shareholders are advised to obtain
recent market quotations for USOP Common Stock and MBE Common Stock. The shares
of USOP Common Stock and MBE Common Stock historically have been subject to
substantial price volatility. No assurance can be given as to the market prices
of USOP Common Stock or MBE Common Stock at any time before the Effective Time
or as to the market price of USOP Common Stock at any time thereafter. See
"Market Price Data."
    
 
                                       24
<PAGE>
   
    In deciding whether to approve the Merger, MBE shareholders should also
consider that, under the terms of the Merger Agreement, the maximum value of the
shares of USOP Common Stock (based upon the Average Price of USOP Common Stock)
to be received by MBE shareholders in the Merger is $29.00 per share of MBE
Common Stock, since if the Average Price of USOP Common Stock exceeds $19.33,
the Exchange Ratio will automatically be adjusted downward to be equal to 1.5
times the quotient of $19.33 divided by the Average Price of USOP Common Stock.
See "The Merger Agreement -- Conversion of Shares." In contrast, there is no
floor on the minimum value (based upon the Average Price of USOP Common Stock)
of the USOP Common Stock to be received by MBE shareholders in the Merger. As
discussed below, if the Average Price of USOP Common Stock is below $15.33 per
share, the Company Board will have the discretion to (i) terminate the Merger
Agreement, in which event the Merger would be terminated unless USOP elects to
adjust the Exchange Ratio upward to provide for $23.00 in value (based upon the
Average Price of USOP Common Stock) per share of MBE Common Stock, or (ii)
proceed with the Merger without any adjustment to the Exchange Ratio, regardless
of what the Average Price of USOP Common Stock is. See "-- Merger Approval
Confers Discretion on Company Board to Terminate or Proceed with Merger if
Average Price of USOP Common Stock is Below $15.33."
    
 
    Because the Averaging Period for determining the Average Price of USOP
Common Stock may extend until as late as two business days before the closing of
the Merger, the Exchange Ratio will not be known with certainty until as late as
such time. Therefore, at the time they vote, MBE shareholders will not know the
number of shares of USOP Common Stock that they will receive in the Merger.
 
   
    MERGER APPROVAL CONFERS DISCRETION ON COMPANY BOARD TO TERMINATE OR PROCEED
     WITH MERGER IF AVERAGE PRICE OF USOP COMMON STOCK IS BELOW $15.33
    
 
   
    Pursuant to the Merger Agreement, if the Average Price of USOP Common Stock
is below $15.33, the Company Board may, without any further vote of MBE
shareholders, elect to (i) terminate the Merger Agreement (in which event the
Merger would be terminated unless USOP were to agree to adjust the Exchange
Ratio to be equal to 1.5 times the quotient of $15.33 divided by the Average
Price of USOP Common Stock and thereby require MBE to proceed with the Merger
(assuming all other conditions to the Merger are satisfied or waived) with such
adjusted Exchange Ratio), or (ii) proceed with the Merger with an Exchange Ratio
equal to 1.5, without any adjustment. Such discretion of the Company Board
presents potential risks to MBE shareholders. For example, if the Average Price
of USOP Common Stock is less than $15.33 per share and the Company Board
determines that it is in the best interests of the Company and its shareholders
to proceed with the Merger, MBE shareholders could receive USOP Common Stock in
the Merger with a fair market value significantly less than $23.00 per share of
MBE Common Stock. Conversely, if the Average Price of USOP Common Stock falls
below $15.33 per share and the Company Board elects to terminate the Merger (and
USOP elects not to adjust the Exchange Ratio), MBE shareholders would not
receive any shares of USOP Common Stock and would instead retain their MBE
shares, the value of which might decline immediately and substantially as a
result of the termination of the Merger. See "The Mail Boxes Etc. Special
Meeting -- Matters to be Considered."
    
 
    FAILURE TO CAPITALIZE ON NEW OPPORTUNITIES
 
    In considering and approving the Merger Agreement and the Merger, USOP's
Board of Directors took into account the opportunities that are expected to
result from the Merger. There can be no assurance that USOP will be able to
capitalize on these opportunities or that it will not encounter substantial
delays or additional costs in connection with this effort. Among the
opportunities that were considered by USOP's Board of Directors are (i) the
potential for USOP to distribute products and services to MBE's customers in the
small office and home office ("SOHO") market (businesses with 20 or fewer
employees); (ii) the ability of MBE franchisees to offer their customers a
broader and more competitively priced array of office products and business
services by taking advantage of the combined purchasing power of USOP and MBE;
and (iii) the potential for USOP and MBE to use their combined
 
                                       25
<PAGE>
purchasing power to negotiate strategic alliances or other arrangements with
vendors that will enable USOP and MBE franchisees to offer their customers
additional, attractive products and services. There can be no assurance that
USOP will be able to capitalize on these opportunities. The failure to
capitalize on these opportunities could have a material adverse effect on the
business, results of operations and financial condition of USOP after completion
of the Merger.
 
    DEPENDENCE UPON RETENTION AND INTEGRATION OF KEY EMPLOYEES
 
    The success of MBE after the Merger is dependent upon the retention and
integration of the key management, sales, marketing and other employees of MBE.
Competition for qualified personnel is keen, and competitors often attempt to
recruit key employees during the period leading up to a merger and during the
integration phase following a merger. Stock options, which generally become
exercisable only over a period of several years of employment, serve as an
important incentive for retaining key employees. In accordance with their terms,
certain stock options held by several key MBE optionees will be fully
exercisable upon the completion of the Merger, thus potentially reducing the
retention incentive provided by such options. There can be no assurance that key
employees will remain with MBE or USOP following the Merger. The loss of
services of any of the key employees of MBE could materially and adversely
affect the business, financial condition and results of operation of MBE and
USOP.
 
    EXPENSES RESULTING FROM THE MERGER
 
    USOP and MBE estimate that they will incur direct transaction costs relating
primarily to regulatory filing costs, and the fees of financial advisors,
attorneys, accountants, financial printers, proxy solicitors and certain other
costs relating to the Merger of approximately $7.0 million associated with the
Merger, which will be charged to operations as nonrecurring acquisition costs.
Of the $7.0 million, $2.5 million was charged to MBE's operations as
nonrecurring Merger costs for its first quarter ended July 31, 1997.

<PAGE>
                                 THE COMPANIES
 
    MBE
 
    The predecessor company to Mail Boxes Etc. (Mail Boxes Etc. USA, Inc. ("MBE
USA")) was established in 1980 in Carlsbad, California by Anthony W. DeSio,
MBE's Vice Chairman of the Board and Chief Executive Officer, and three other
individuals. Mail Boxes Etc., which DeSio and another outside investor founded,
acquired MBE USA in 1983. MBE became a publicly held company in 1986. Today, MBE
is the world's largest franchisor of postal, business and communications retail
service centers.
 
    There are more than 2,800 MBE centers operating throughout the United States
and more than 500 MBE centers serving customers outside the U.S. With MBE master
licenses in place in more than 50 countries abroad, the Company's distribution
network is approximately ten times larger than that of its nearest competitor.
 
    MBE is a service-based company. It has grown far beyond its original
business of providing customers with alternative retail services to the U.S.
Post Office. MBE today offers a broad spectrum of business and communications
solutions, including packing and shipping, photocopying, faxing and mail
receiving services, office supplies and other related services. MBE centers are
also used by large corporations that need a national distribution system to
dispense a variety of services to their customers and field-based employees.
 
    The primary sources of revenues for the Company are (1) royalty and
marketing fees paid by franchisees, (2) fees paid by buyers of new franchises,
and (3) sales of supplies and equipment to MBE centers.
 
    MBE sells franchises in the United States by using its own sales force and
its national network of over 90 area franchisees. In international markets, the
Company sells master licenses for the rights to operate in countries other than
the United States. The master licensees in turn have the right to sell area
franchises and individual franchises in their own countries.
 
    USOP
 
    USOP is one of the world's largest and fastest growing suppliers of a broad
range of office and educational products and business services to corporate,
commercial, industrial and educational customers. Since its founding in October
1994, USOP has emerged as a leading consolidator of several highly fragmented
industries that serve the needs of its customers. USOP currently provides
products and services from over 450 facilities in the United States, and from
over 400 facilities in New Zealand, Australia and Canada. USOP also operates in
the United Kingdom through Dudley. USOP currently has over 18,000 employees.
 
    USOP's strategy has been to serve as the sole source for the full range of
products and business services used by middle market businesses and educational
institutions around the world. USOP believes that middle market businesses,
which it defines as businesses with between 20 and 500 employees, constitute one
of the fastest growing sectors of the economy and have served as a greater
source of new job growth in recent years than have larger organizations. USOP
sells a full range of products and services, including office supplies, office
furniture, print and forms management services, technology network services and
equipment, corporate travel services, school supplies and furniture and office
coffee and beverage services. USOP's goal is to be the provider of choice for
all of a customer's office needs by offering superior customer service,
convenience and a full range of products and services.
 
    If the Merger is approved by MBE's shareholders, USOP expects to expand its
customer base to include MBE's customers, which are primarily the SOHO market.
USOP believes it will be able to offer its
 
                                       27
<PAGE>
broad range of products and services to these new customers and thereby provide
those customers with the opportunity to meet all of their office needs through
USOP.
 
    USOP has an aggressive acquisition program through which it has acquired and
seeks to acquire companies with established sales presences and brand names in
given geographic, product or service markets. Since its initial public offering
in February 1995 through September 3, 1997, USOP has completed more than 190
acquisitions. USOP believes that the fragmented nature of many of the markets it
serves has both allowed it to identify suitable acquisition candidates and
enabled it, through acquisitions, to establish a leadership position in these
markets. For example, USOP believes that, based upon current sales volume, it is
now one of the largest contract stationers in the United States, one of the
largest school supply distributors in the United States, one of the largest
providers of office coffee services in the United States and one of the largest
providers of contract furniture in the United States. USOP is currently
organized into eight divisions to serve its various product, service and
geographic markets, and to identify and pursue strategic acquisitions within
these markets.
 
    SUB
 
    Sub is a California corporation organized in May 1997. Sub has not carried
on any significant activities other than activities undertaken in connection
with the Merger Agreement and the transactions contemplated thereby. The mailing
address and telephone number of Sub are the same as those for USOP.

                      THE MAIL BOXES ETC. SPECIAL MEETING
 
    GENERAL
 
   
    This Proxy Statement/Prospectus is being furnished to holders of MBE Common
Stock in connection with the solicitation of proxies by the Company Board for
use at the Special Meeting to be held on          , November   , 1997, at 6060
Cornerstone Court West, San Diego, California 92121, commencing at 9:00 a.m.,
Pacific Standard Time, and at any adjournment or postponement thereof.
    
 
    MATTERS TO BE CONSIDERED
 
    At the Special Meeting, holders of MBE Common Stock will consider and vote
upon a proposal to approve the principal terms of the Merger and such other
matters as may properly be brought before the Special Meeting.
 
   
    One of the principal terms of the Merger Agreement allows MBE to terminate
the Merger Agreement if the Average Price of USOP Common Stock is less than
$15.33 per share and if USOP does not elect to adjust the Exchange Ratio to
provide that MBE shareholders will receive $23.00 in value (based upon the
Average Price of USOP Common Stock) per share of MBE Common Stock in the Merger.
The Company Board does not currently plan to submit to a further shareholder
vote the question of whether to give notice to USOP to terminate the Merger or
to proceed with the Merger with an unadjusted Exchange Ratio if the Average
Price of USOP Common Stock is below $15.33. Under the CGCL, the Company Board
may, in its discretion, abandon a merger without further approval by the
outstanding shares at any time before the merger is effective. However, the
Company Board's discretion to terminate or proceed with the Merger is subject to
its fiduciary duties to MBE shareholders under applicable law. In general, these
fiduciary duties require the Company Board to act in good faith, in a manner the
directors believe to be in the best interests of the Company and its
shareholders and with such care as an ordinarily prudent person would use under
similar circumstances. The Company Board will consider the following factors in
deciding whether to terminate or proceed with the Merger if the Average Price of
USOP Common Stock is below $15.33 per share: (i) whether the reasons the Company
Board originally recommended approval of the Merger remain valid (see "The
Merger -- Recommendation of the Board of Directors of MBE and MBE's Reasons for
the Merger"); (ii) how far below $15.33 the Average Price of USOP Common Stock
is at the time of the decision; (iii) the causes of the decline in the Average
Price of USOP Common Stock; (iv) the business prospects and outlook for USOP and
MBE (individually and on a combined basis); and (v) prevailing market
conditions. In connection with its decision, the Company Board will consult with
its financial and legal advisors. See "Risk Factors -- Special Considerations
with Respect to the Merger -- Merger Approval Confers Discretion on Company
Board to Terminate or Proceed with Merger if Average Price of USOP Common Stock
is Below $15.33."
    
 
    RECOMMENDATION OF THE BOARD OF DIRECTORS OF MAIL BOXES ETC.
 
    The Company Board believes that the terms of the Merger Agreement are fair
to, and in the best interests of, the Company and its shareholders. THE BOARD OF
DIRECTORS OF MAIL BOXES ETC. HAS UNANIMOUSLY APPROVED THE MERGER AGREEMENT AND
RECOMMENDS A VOTE FOR APPROVAL OF THE PRINCIPAL TERMS OF THE MERGER.
 
    RECORD DATE; VOTING RIGHTS; PROXIES; INDEPENDENT PUBLIC ACCOUNTANTS
 
   
    The Company Board has fixed the close of business on September 30, 1997 as
the Record Date for determining holders entitled to notice of and to vote at the
Special Meeting. As of the Record Date, there were 11,400,302 shares of MBE
Common Stock issued and outstanding, each of which entitles the holder thereof
to one vote, which shares were held by approximately 670 holders of record.
    
 
                                       29
<PAGE>
    The approval of the Merger requires the affirmative vote of the holders of a
majority of the outstanding shares of MBE Common Stock as of the Record Date.
 
    THE MATTERS TO BE CONSIDERED AT THE SPECIAL MEETING ARE OF GREAT IMPORTANCE
TO SHAREHOLDERS. ACCORDINGLY, SHAREHOLDERS ARE URGED TO READ AND CAREFULLY
CONSIDER THE INFORMATION PRESENTED IN THIS PROXY STATEMENT/PROSPECTUS, AND TO
COMPLETE, DATE, SIGN AND PROMPTLY RETURN THE ENCLOSED PROXY CARD IN THE ENCLOSED
ENVELOPE.
 
    All shares of MBE Common Stock represented by properly executed proxies
will, unless such proxies have been previously revoked, be voted and will be
voted in accordance with the instructions indicated in such proxies. IF NO
INSTRUCTIONS ARE INDICATED, SUCH SHARES OF MBE COMMON STOCK WILL BE VOTED FOR
APPROVAL OF THE PRINCIPAL TERMS OF THE MERGER. MBE does not know of any matters
other than as described in the Notice of Special Meeting of Shareholders that
are to come before the Special Meeting. If any other matter or matters are
properly presented for action at the Special Meeting, the persons named in the
enclosed form of proxy and acting thereunder will have discretion to vote on
such matters. A shareholder who has given a proxy may revoke it at any time
before it is exercised by giving written notice of revocation to the Secretary
of MBE, by signing and returning a later dated proxy or by voting in person at
the Special Meeting; however, mere attendance at the Special Meeting will not in
and of itself have the effect of revoking the proxy. The presence, in person or
by properly executed proxy, of the holders of a majority of the outstanding
shares of MBE Common Stock entitled to vote at the Special Meeting is necessary
to constitute a quorum at the Special Meeting.
 
    Abstentions and broker non-votes will be treated as present for quorum
purposes, but will not be counted as voted for purposes of determining the
approval of any matter submitted to shareholders for a vote. The term "broker
non-votes" refers to shares held by a broker in street name which are present by
proxy but are not voted on a matter pursuant to rules prohibiting brokers from
voting on non-routine matters, such as approval of the Merger, without
instructions from the beneficial owner of the shares. Because the approval of
the Merger by shareholders of MBE requires the affirmative vote of a majority of
the shares of MBE Common Stock outstanding as of the Record Date, failure to
submit a proxy, an abstention or a broker non-vote will each have the same
effect as a vote against approval of the Merger.
 
    It is expected that one or more representatives of Ernst & Young LLP will be
present at the Special Meeting. The representative(s) will have the opportunity
to make a statement and to respond to appropriate questions.
 
    PERSONAL SOLICITATIONS AND SHARED COSTS
 
    All expenses of MBE's solicitation of proxies, including the cost of mailing
this Proxy Statement/ Prospectus, will be borne by MBE. In addition to
solicitation by use of the mails, proxies may be solicited from MBE shareholders
by directors, officers and employees of MBE in person or by telephone, telegram
or other means of communication. Such directors, officers and employees will not
be additionally compensated, but may be reimbursed for reasonable out-of-pocket
expenses in connection with such solicitation. MBE has retained MacKenzie
Partners, Inc., a proxy solicitation firm, for assistance in connection with the
solicitation of proxies for the Special Meeting at a cost of $5,000 plus
reimbursement for reasonable out-of-pocket expenses. Arrangements will also be
made with brokerage houses, custodians, nominees and fiduciaries for forwarding
of proxy solicitation materials to beneficial owners of shares held of record by
such brokerage houses, custodians, nominees and fiduciaries, and MBE will
reimburse such brokerage houses, custodians, nominees and fiduciaries for their
reasonable expenses incurred in connection therewith.

                                   THE MERGER
 
GENERAL DESCRIPTION OF THE MERGER
 
   
    On May 22, 1997, USOP, MBE and Sub signed the Merger Agreement. As of
October 9, 1997, USOP, MBE and Sub amended the Merger Agreement to take into
account the stock split announced by USOP on October 7, 1997. Prior to the
declaration of the stock split and the amendment of the Merger Agreement, each
share of Company Common Stock was to be exchanged for 1 share of USOP Common
Stock, subject to adjustment if the Average Price of USOP Common Stock was less
than $23.00 or more than $29.00. The amendment adjusted the Exchange Ratio to
1.5 shares of USOP Common Stock for each share of Company Common Stock, subject
to adjustment if the Average Price of USOP Common Stock is less than $15.33 or
more than $19.33, to reflect the impact of the stock split and preserve the
economic terms of the Merger as originally agreed to by USOP and MBE prior to
the declaration of the stock split. If the Average Price of USOP Common Stock is
more than $19.33, the Company's shareholders will receive for each share of MBE
Common Stock that number of shares of USOP Common Stock equal to 1.5 times the
quotient of $19.33 divided by the Average Price of USOP Common Stock. If the
Average Price of USOP Common Stock is less than $15.33 and if MBE elects to
terminate the Merger Agreement, USOP has the option, but not the obligation, to
adjust the Exchange Ratio to be equal to 1.5 times the quotient of $15.33
divided by the Average Price of USOP Common Stock. If USOP adjusts the Exchange
Ratio as described, MBE must accept the adjustment and, assuming all conditions
to the Merger are satisfied or waived, proceed with the Merger. If the Average
Price of USOP Common Stock is less than $15.33 and MBE does not elect to
terminate the Merger Agreement, the Exchange Ratio will not change. Each of the
shareholders of MBE Common Stock who would be entitled to receive a fractional
share of USOP Common Stock upon surrender of such shareholder's shares of MBE
Common Stock will receive, in lieu thereof, cash in an amount equal to the value
of such fractional share.
    
 
STOCK OPTIONS
 
    Upon the closing of the Merger, each outstanding and unexercised option to
purchase shares of MBE Common Stock will be assumed by USOP and converted into
an option to purchase the Option Conversion Number (as defined below) of shares
of USOP Common Stock at an exercise price per share equal to the Adjusted
Exercise Price (as defined below). The term "Option Conversion Number" is
defined in the Merger Agreement as the number of shares of MBE Common Stock
purchasable pursuant to the original option multiplied by the Exchange Ratio.
The term "Adjusted Exercise Price" is defined in the Merger Agreement as the
exercise price of the original option divided by the Exchange Ratio. Such
assumed option will otherwise have substantially the same terms and conditions
as the option to which it is related, including the same vesting schedule (other
than to the extent accelerated pursuant to the terms of such option or in
accordance with the terms of any employment agreements existing as of the date
of the Merger Agreement).
 
EFFECTIVE TIME OF THE MERGER
 
    On the closing date of the Merger, the parties will file with the California
Secretary of State (i) a copy of the Merger Agreement, (ii) an officer's
certificate for each of Sub and MBE, and (iii) a certificate of satisfaction of
the California Franchise Tax Board for Sub, all as required by Section 1103 of
the CGCL, and will make all other filings or recordings required under the CGCL.
The Merger will become effective at such time as the Merger Documents are duly
filed with the California Secretary of State, or at such other time as Sub and
MBE may agree to specify in the documents to be filed with the Secretary of
State. Assuming all conditions to the Merger contained in the Merger Agreement
are satisfied or waived prior thereto, it is currently anticipated that the
Effective Time will occur as soon as practicable following the Special Meeting.
 
                                       31
<PAGE>
PROCEDURES FOR EXCHANGE OF CERTIFICATES
 
    As soon as reasonably practicable after the Effective Time, USOP will cause
to be mailed to holders of record of MBE Common Stock on the Record Date (a) a
letter of transmittal and (b) instructions for effecting the exchange of
certificates representing MBE Common Stock for certificates representing USOP
Common Stock. Upon surrender of certificates representing MBE Common Stock, the
executed letter of transmittal and other reasonably required documents, former
holders of MBE Common Stock will receive shares of USOP Common Stock and cash in
lieu of fractional shares. SHAREHOLDERS SHOULD NOT SEND THEIR CERTIFICATES WITH
THEIR PROXY CARD.
 
BACKGROUND OF THE MERGER
 
   
    References in the discussion below to the price of USOP Common Stock do not
reflect the effect of the stock split.
    
 
    On September 20, 1996, the Company Board met to discuss the possibility of
exploring MBE's strategic and financial alternatives, including possible
strategic relationships with other companies, for the purpose of maximizing
shareholder value. The Company Board authorized its Executive Committee to
pursue exploratory discussions with investment bankers regarding a possible role
as financial advisor to the Company.
 
    In October 1996, the Company Board met to discuss the possible hiring of a
financial advisor to assist MBE in analyzing its strategic and financial
alternatives. The Company Board then authorized the Executive Committee to
retain AACC to act as MBE's exclusive financial advisor.
 
    From November 1996 through January 1997, representatives of the Executive
Committee together with senior officers of MBE met with AACC to discuss the
scope of the assignment to be undertaken by AACC and the proposed process to be
followed. On December 4, 1996, MBE executed an engagement letter agreement with
AACC (the "Engagement Letter"). In addition, AACC and MBE developed a list of
possible strategic acquirors to be contacted during the process. AACC also
conducted a financial analysis of MBE and the potential strategic acquirors and
prepared a confidential memorandum describing MBE (the "Confidential
Memorandum").
 
    In February 1997, AACC began to contact potentially interested strategic
acquirors and to distribute certain materials, including the Confidential
Memorandum, for them to review. A total of 23 potential strategic acquirors were
contacted. Of the 23 initial contacts, seven companies reviewed public materials
and then declined interest. Five companies, including USOP, signed
confidentiality agreements and received the Confidential Memorandum. The other
parties declined interest in pursuing the opportunity.
 
    On March 20, 1997, AACC received preliminary indications of interest from
two parties (each, an "Interested Party" and together, the "Interested
Parties"). USOP submitted a preliminary proposal setting forth a fixed
one-for-one share exchange ratio in a tax-free exchange that would receive
pooling-of-interests accounting treatment. On March 20, 1997, the last reported
sale price of USOP Common Stock on the Nasdaq National Market was $25.13 per
share. The other Interested Party (the "Second Interested Party") submitted a
preliminary proposal of an exchange of a fraction of its shares having a value
of between $23.00 and $25.00 for each outstanding share of MBE Common Stock.
This floating exchange ratio would have been subject to a mutually agreed upon
"collar", would have been tax-free and would have been accounted for under the
pooling-of-interests method of accounting.
 
    On March 24, 1997, the Company Board met with AACC to review the preliminary
proposals and discuss the process to date and the next steps to be taken. In
particular, the Company Board discussed whether AACC should continue discussions
with the Interested Parties and whether the Interested Parties should be invited
to meet with key management of MBE. The Company Board directed AACC to continue
to have discussions with the Interested Parties and to proceed with management
meetings between the Interested Parties and MBE.

    On both April 2 and 3, 1997, key management from MBE and AACC met with key
management from USOP in San Diego. During these meetings, MBE presented an
overview of the operations of MBE and recent developments, including a
description of new strategic initiatives. USOP presented an overview of its
operations to MBE.
 
    On April 9, 1997, key management from MBE and AACC met with a senior officer
from the Second Interested Party in San Diego. During this meeting, MBE
presented an overview of its operations and recent developments. The Second
Interested Party presented an overview of its operations to MBE.
 
    On April 17, 1997, senior management from MBE and AACC met with additional
members of the senior management team from USOP in Washington, D.C. MBE and USOP
continued to discuss possible advantages of a combination, and USOP explained in
more detail its corporate history, operations, strategy and growth plans.
 
    On May 1 and 2, 1997, AACC received revised indications of interest through
several telephone conversations with the Interested Parties. After some
negotiation, USOP proposed a floating exchange ratio having a value equal to
$26.25 per MBE share. USOP's Common Stock price at this time was $24.75. The
Second Interested Party proposed an exchange of a fraction of its shares, which
at that time represented a value less than that represented by the USOP
proposal. On May 2, 1997, the Executive Committee met with AACC to discuss the
revised proposals from the Interested Parties. The Executive Committee directed
AACC to continue to negotiate with USOP.
 
    During the following weeks, Frederic Floberg, Senior Managing Director of
AACC, had several discussions with Jonathan Ledecky, CEO and Chairman of the
USOP Board, regarding a possible strategic transaction. On May 15, 1997, Mr.
Ledecky indicated that members of the Executive Committee of USOP's Board of
Directors were concerned about the previously discussed fixed value offer of
$26.25 per share of MBE Common Stock because the then current price of USOP
Common Stock had declined to $23.88 per share and USOP was concerned about the
potential dilution to USOP stockholders that could result from a fixed value
offer.
 
   
    On May 16, 1997, USOP returned to its original proposal, which consisted of
the terms in the Merger Agreement prior to its amendment to reflect the stock
split. These terms were as follows: the Exchange Ratio would be one as long as
the Average Price of USOP Common Stock was between $23.00 and $29.00 per share;
if the Average Price of USOP Common Stock was above $29.00, then the Exchange
Ratio would be a fraction of a share of USOP Common Stock equal to the quotient
of $29.00 divided by the Average Price of USOP Common Stock; if the Average
Price of USOP Common Stock was below $23.00, then there would be no automatic
adjustment in the Exchange Ratio, and the Company could terminate the Merger
Agreement unless USOP should elect to adjust the Exchange Ratio to be equal to
the quotient of $23.00 divided by the Average Price of USOP Common Stock. Mr.
Ledecky, Mark D. Director, Chief Administrative Officer, General Counsel and
Secretary of USOP, Michael Dooling, Chairman of the Board of Directors, and
Anthony W. DeSio, Chief Executive Officer of MBE, and their respective advisors
subsequently proceeded with the negotiation of a draft of the Merger Agreement.
    
 
    The Company Board met on May 20, 1997 with Mr. Floberg and other AACC
representatives and counsel in attendance and reviewed a draft of the Merger
Agreement. The purpose of the meeting was to give final consideration as to
whether any other alternatives (e.g. continuing as an independent company for
the time being) might present a better value for the shareholders of MBE, to
consider the terms of the proposed draft contract, to receive and consider the
advice of AACC with respect to the fairness of the proposed transaction with
USOP and to determine whether or not to continue to negotiate the contract. At
the Company Board meeting, AACC summarized for the Company Board the results of
its analyses undertaken for purposes of rendering an opinion relating to the
proposed transaction with USOP. Such analyses included a review of the stock
price history of the MBE Common Stock and the USOP Common Stock, a comparison of
MBE and USOP with other publicly traded companies, an analysis of the
contribution of MBE to the financial results and condition of USOP resulting
from the contemplated
 
                                       33
<PAGE>
transaction and an analysis of the transaction in comparison to selected other
acquisition transactions in the franchise industry. The AACC presentation also
included a discounted cash flow analysis for MBE, a present value analysis of
possible future stock prices of MBE Common Stock and a pro forma merger
analysis. These analyses are summarized elsewhere in this Proxy
Statement/Prospectus. See "-- Opinion of Financial Advisor." AACC also rendered
its opinion, confirmed in writing as of May 22, 1997, that as of such date and
subject to the assumptions and limitations identified in the opinion, the
Exchange Ratio to be received by the shareholders of MBE is fair to such
shareholders from a financial point of view. See "-- Opinion of Financial
Advisor."
 
    The Company Board concluded that the process employed to solicit proposals
for transactions was conducted in such a manner as to result in the most
attractive alternative available to the shareholders of MBE and that the USOP
proposal offered a better opportunity for enhancing shareholder value than that
offered by the continuation of MBE as an independent company for the time being.
Accordingly, the Company Board directed its representatives to complete the
negotiation of the Merger Agreement. After the close of the market on May 21,
1997, the Company Board had several follow-up teleconference meetings and
determined that the proposed transaction was in the best interests of MBE's
shareholders, unanimously approved the final form of the agreement between MBE
and USOP and authorized MBE's officers to execute the Merger Agreement. After
the meetings of the Company Board and USOP's Board of Directors, the Merger
Agreement was executed by the parties and a press release announcing the
proposed transaction was issued before the commencement of trading on Thursday,
May 22, 1997.
 
RECOMMENDATION OF THE BOARD OF DIRECTORS OF MBE AND MBE'S REASONS FOR THE MERGER
 
    The Company Board unanimously approved the Merger and recommends that
shareholders vote FOR approval and adoption of the principal terms of the
Merger. The Company Board believes that the Merger is fair to and in the best
interests of the shareholders of MBE. The Company Board considered the terms and
structure of the Merger and the terms and conditions of the Merger Agreement and
decided to approve the Merger and recommended unanimously that the shareholders
approve the principal terms of the Merger, in light of the following factors:
 
    (i) the fact that the Merger Agreement resulted from a comprehensive process
that the Company Board believes was conducted in such a manner as to result in
the most attractive alternative available to the shareholders of MBE (see
"--Background of the Merger");
 
    (ii) the information presented by AACC at the May 20, 1997 meeting of the
Company Board and the written opinion of AACC dated May 22, 1997, to the effect
that the Exchange Ratio is fair to the MBE shareholders. SHAREHOLDERS ARE URGED
TO READ THE OPINION OF AACC IN ITS ENTIRETY. THIS OPINION IS INCLUDED AS EXHIBIT
II TO THIS PROXY STATEMENT/ PROSPECTUS.
 
    (iii) the strategic and financial alternatives available to MBE, including
remaining an independent company and pursuing its existing growth strategy;
 
    (iv) information with respect to the financial condition and business of
USOP, including, among other things, USOP's recent earnings performance, and the
demonstrated ability of USOP to successfully implement its growth strategy;
 
    (v) current and historical market prices and trading information with
respect to each company's common stock;
 
    (vi) the fact that the USOP Common Stock to be exchanged for MBE Common
Stock represents ownership interests in a significantly larger company with a
significantly broader, more active trading market;
 
    (vii) the length of time that would be required if the Merger were not
completed to achieve the shareholder value to be received by the MBE
shareholders through the Merger;
 
                                       34
<PAGE>
    (viii) the fact that, under the Merger Agreement, the Merger is expected to
be treated as a tax-free reorganization under the Code;
 
    (ix) the expected accounting treatment of the Merger as a
pooling-of-interests (thereby avoiding the reduction in future earnings which
would result under purchase accounting);
 
    (x) the fact that the implied value resulting from the Exchange Ratio to be
received by MBE shareholders represents a premium of 24.8% over the
pre-announcement market price of MBE Common Stock;
 
    (xi) the history of MBE's contacts with other prospective parties;
 
    (xii) the financial strength of, and consolidation opportunities available
to, USOP and its management;
 
    (xiii) the fact that, under the Merger Agreement, the Company Board is
permitted, under certain circumstances and subject to certain notice and other
requirements specified in the Merger Agreement, to provide information to or
enter into discussions or negotiations with any person or entity that makes an
unsolicited, Superior Proposal, as defined below and in the Merger Agreement
(see "The Merger Agreement--Certain Covenants--No Inconsistent Activities"); and
 
    (xiv) the published reports of research analysts regarding USOP's long-term
growth prospects and the potential for share price appreciation, some of which
reports reflect target stock prices substantially above USOP's current stock
price, and the opportunity for MBE shareholders to participate in this potential
appreciation.
 
    The foregoing discussion of the information and factors considered by the
Company Board is not intended to be exhaustive. The information and factors were
considered by the Company Board in connection with its review of the Merger
Agreement and the proposed Merger. In view of the variety of factors considered
in connection with its evaluation of the Merger, the Company Board did not find
it practicable to, and did not, quantify or otherwise assign relative weights to
the specific factors considered in reaching its determination. In addition,
individual members of the Company Board may have given different weights to
different factors. Based upon this analysis, the Company Board determined that
the Merger was in the best interests of the shareholders of MBE.
 
OPINION OF FINANCIAL ADVISOR
 
    MBE retained AACC to act as its financial advisor in connection with a
possible transaction to enhance shareholder value. In connection with such
engagement, MBE requested that AACC render its opinion as to the fairness to
MBE's shareholders of the Exchange Ratio to be received in the Merger.
 
    On May 22, 1997, in connection with the evaluation of the proposal from USOP
by the Company Board, AACC rendered an opinion that, as of such date, and
subject to certain assumptions, factors and limitations set forth in such
written opinion as described below, the Exchange Ratio to be received by MBE
shareholders is fair to such shareholders from a financial point of view.
 
   
    THE FULL TEXT OF THE WRITTEN OPINION OF AACC, DATED MAY 22, 1997, WHICH SETS
FORTH THE ASSUMPTIONS MADE, MATTERS CONSIDERED AND LIMITATIONS ON THE REVIEW
UNDERTAKEN IN CONNECTION WITH THE OPINION, IS ATTACHED AS APPENDIX II TO THIS
PROXY STATEMENT/PROSPECTUS AND SHOULD BE READ IN ITS ENTIRETY FOR INFORMATION
WITH RESPECT TO PROCEDURES FOLLOWED, ASSUMPTIONS MADE AND MATTERS CONSIDERED BY
AACC IN RENDERING ITS OPINION. AACC'S OPINION DOES NOT REFLECT THE STOCK SPLIT
ANNOUNCED BY USOP ON OCTOBER 7, 1997. AACC'S OPINION WAS PREPARED FOR THE
COMPANY BOARD AND ADDRESSES ONLY THE FAIRNESS OF THE EXCHANGE RATIO TO THE
HOLDERS OF MBE COMMON STOCK. THE AACC OPINION DOES NOT CONSTITUTE A
RECOMMENDATION TO ANY SHAREHOLDER AS TO HOW SUCH SHAREHOLDER SHOULD VOTE WITH
RESPECT TO THE PROPOSED MERGER AND DOES NOT CONSTITUTE AN OPINION AS TO WHAT THE
VALUE OF USOP COMMON STOCK ACTUALLY WILL BE WHEN ISSUED TO MBE SHAREHOLDERS
PURSUANT TO THE MERGER. THE SUMMARY OF THE OPINION OF AACC SET FORTH IN THIS
PROXY STATEMENT/PROSPECTUS IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL
TEXT OF THE OPINION.
    
 
                                       35
<PAGE>
    In connection with its opinion, AACC reviewed the Merger Agreement and
certain related documents and held discussions with certain senior officers,
directors and other representatives and advisors of MBE and certain senior
officers and other representatives of USOP concerning the businesses, operations
and prospects of MBE and USOP. AACC examined certain publicly available business
and financial information relating to MBE and USOP, as well as certain financial
data and other data for MBE and certain financial information and other data
related to USOP which were provided to or otherwise discussed with AACC by the
respective management of MBE and USOP. AACC reviewed the financial terms of the
Merger as set forth in the Merger Agreement in relation to: (i) current and
historical market prices and trading volumes of MBE Common Stock and USOP Common
Stock; (ii) the respective companies' financial and other operating data; and
(iii) the capitalization and financial condition of MBE and USOP. AACC also
considered, to the extent publicly available, the financial terms of certain
other similar transactions recently effected which AACC considered relevant in
evaluating the Merger and analyzed certain financial, stock market and other
publicly available information relating to the businesses of other companies
whose operations AACC considered relevant in evaluating those of MBE and USOP.
In connection with AACC's engagement, AACC identified, approached and held
discussions with certain third parties to solicit indications of interest in a
possible acquisition of MBE.
 
    In rendering its opinion, AACC assumed and relied upon the accuracy and
completeness of the financial and other information reviewed by it, and it did
not make, obtain or assume any responsibility for independent verification of
such information. In addition, AACC did not make an independent evaluation or
appraisal of the assets and liabilities of MBE or USOP or any of their
respective subsidiaries.
 
   
    The following is a summary of the financial analyses AACC utilized in
connection with providing its written opinion to the Company Board on May 20,
1997. The prices of USOP Common Stock referenced in this summary do not reflect
the stock split.
    
 
    (a)  STOCK TRADING HISTORY.  AACC examined the history of the closing prices
and trading volumes for the shares of MBE Common Stock. This examination showed
that during the four week period from April 21, 1997 to May 16, 1997, the
closing price of MBE Common Stock ranged from $21.00 per share to $18.00 per
share. This range may be compared to the range of values to be received pursuant
to the Exchange Ratio. In addition, this examination showed that over the period
from May 16, 1996 to May 16, 1997, the closing price of MBE Common Stock ranged
from $25.88 per share to $16.50 per share. AACC also examined the history of the
closing prices and trading volumes for the shares of USOP Common Stock. This
examination showed that during the four-week period from April 21, 1997 to May
16, 1997, the closing price of USOP Common Stock ranged from $26.25 per share to
$20.50 per share. In addition, this examination showed that over the period from
May 16, 1996 to May 16, 1997, the closing price of USOP Common Stock ranged from
$44.88 per share to $20.50 per share.
 
    (b)  COMPARISON OF SELECTED PEER COMPANIES.  AACC compared selected
historical stock market and balance sheet data and historical or pro forma
financial ratios for MBE and USOP to the corresponding data and ratios of the
following group of selected franchisor companies (in the case of MBE) and groups
of office products distribution companies (in the case of USOP) and the
companies indicated within each such group: (a) Franchisor Group: Boston
Chicken, Inc., General Nutrition Companies, HFS, Incorporated, McDonald's
Corporation, Papa John's International; (b) Office Products Distribution-- (i)
Contract Stationers: Boise Cascade Office Products, BT Office Products,
Corporate Express, (ii) Office Superstores: Office Depot, OfficeMax, Staples,
and (iii) Mail Order: Viking Office Products. The multiples of MBE and USOP were
calculated using a price of $19.00 per share of MBE Common Stock and a price of
$23.75 per share of USOP Common Stock, the closing prices as of May 16, 1997.
Such data and ratios included, among other things, total market capitalization
(current stock price multiplied by shares outstanding plus total debt less cash
and cash equivalents), total market capitalization to latest 12 months ("LTM")
sales, LTM earnings before interest, taxes, depreciation and amortization
("EBITDA") and LTM earnings before interest and taxes ("EBIT"), as well as
calendar year 1997 and 1998 estimated price-to-earnings ("P/E") ratios. The LTM
data for MBE was based upon MBE's reported results for the period ended January
31,
 
                                       36
<PAGE>
1997, adjusted for the one-time litigation charge incurred in MBE's second
quarter of its 1997 fiscal year. The LTM data for USOP was based upon USOP's pro
forma reported results for the period ended January 25, 1997, excluding MBE, and
adjusted for nonrecurring items. For the franchisor companies, an analysis of
total market capitalization to LTM sales yielded a range of 9.8x to 2.1x (with a
median of 3.8x) compared to 2.9x for MBE. For the office products companies, an
analysis of total market capitalization to LTM sales yielded a range of 1.1x to
0.3x (with a median of 0.6x) compared to 0.7x for USOP. For the franchisor
companies, an analysis of total market capitalization to LTM EBITDA yielded a
range of 20.7x to 12.1x (with a median of 13.5x) compared to 10.9x for MBE. For
the office products companies, an analysis of total market capitalization to LTM
EBITDA yielded a range of 15.0x to 7.3x (with a median of 10.1x) compared to
11.9x for USOP. For the franchisor companies, an analysis of total market
capitalization to LTM EBIT yielded a range of 27.9x to 15.4x (with a median of
16.3x) compared to 11.6x for MBE. For the office products companies, an analysis
of total market capitalization to LTM EBIT yielded a range of 19.1x to 11.4x
(with a median of 14.0x) compared to 14.2x for USOP. For the franchisor
companies, an analysis of calendar 1997 estimated P/E ratios yielded a range of
32.1x to 15.7x (with a median of 20.9x) compared to 17.8x for MBE. For the
office products companies, an analysis of calendar 1997 estimated P/E ratios
yielded a range of 27.0x to 12.9x (with a median of 18.4x) compared to 16.3x for
USOP. For the franchisor companies, an analysis of calendar 1998 estimated P/E
ratios yielded a range of 24.6x to 12.1x (with a median of 16.4x) compared to
14.8x for MBE. For office products companies, an analysis of calendar 1998
estimated P/E ratios yielded a range of 21.1x to 11.1x (with a median of 15.0x)
compared to 12.4x for USOP.
 
    (c)  SELECTED TRANSACTIONS ANALYSIS.  AACC analyzed certain information
relating to selected transactions in the franchising industry (the "Selected
Transactions"). Such analysis indicated that for the Selected Transactions, (i)
aggregate consideration as a multiple of LTM sales ranged from 6.2x to 0.6x with
a median of 2.2x compared to a multiple of 3.6x at $23.00 per share and 4.6x at
$29.00 per share for the Merger (per share amounts reflect the range of possible
offer prices for MBE Common Stock), (ii) aggregate consideration as a multiple
of LTM EBITDA ranged from 15.8x to 4.4x with a median of 8.9x compared to a
multiple of 13.5x at $23.00 per share and 17.4x at $29.00 per share for the
Merger, (iii) aggregate consideration as a multiple of LTM EBIT ranged from
28.0x to 9.5x with a median of 14.2x compared to a multiple of 14.4x at $23.00
per share and 18.5x at $29.00 per share for the Merger, and (iv) equity
consideration as a multiple of LTM net income ranged from 30.4x to 14.9x with a
median of 21.2x compared to a multiple of 25.2x at $23.00 per share to 31.7x at
$29.00 per share for the Merger.
 
    (d)  CONTRIBUTION ANALYSIS.  AACC reviewed certain historical operating and
financial information (including, among other things, revenue, EBIT, net income
and market capitalization) for MBE, USOP and the pro forma financial information
reflecting the Merger and other transactions of USOP. This analysis indicated
that MBE would have contributed (i) 2.3% to pro forma combined revenue, 10.0% to
pro forma combined EBIT and 12.2% to pro forma combined net income, in each case
for the twelve month period ended January 31, 1997 and assuming that the Merger
had occurred on February 1, 1996, and (ii) 14.0% to pro forma combined total
market capitalization and 14.6% to pro forma combined ownership, in each case as
of May 16, 1997 and assuming that the Merger had occurred as of that date.
 
    (e)  DISCOUNTED CASH FLOW ANALYSIS.  AACC performed a discounted cash flow
analysis of MBE. AACC calculated a net present value of estimated cash flows as
provided by MBE management for the fiscal years ended April 30, 1998 through
2001 using discount rates ranging from 13.0% to 17.0%. AACC calculated MBE's
terminal values in the fiscal year 2001 based on multiples ranging from 8x EBIT
to 11x EBIT. These terminal values were then discounted to present value using
discount rates from 13.0% to 17.0%. Using the foregoing terminal values and
discounted cash flows for MBE, the equity value per share ranged from $19.99 to
$28.51.
 
    (f)  PRESENT VALUE OF PROJECTED STOCK PRICE ANALYSIS.  AACC calculated the
present value of a share of MBE Common Stock assuming various growth rates
applied to estimated fiscal year 1997 earnings per share. Earnings per share
multiples ranging from 15.0x to 22.5x were applied to the fiscal year 2001
 
                                       37
<PAGE>
estimated earnings per share, and then discounted at rates ranging from 13.0% to
17.0%. The present value suggested a range of valuation for MBE between $14.55
per share and $28.06 per share.
 
    The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to practical analysis or summary description. Selecting
portions of the analyses or of the summary set forth above, without considering
the analyses as a whole, could create an incomplete view of the processes
underlying AACC's opinion. In arriving at its fairness determination, AACC
considered the results of all of such analyses. No company or transaction used
in the above analyses as a comparison is identical to MBE or USOP or the Merger.
The analyses were prepared solely for purposes of AACC's opinion provided to the
Company Board as to the fairness of the Exchange Ratio to be received by the
shareholders of MBE pursuant to the Merger Agreement and do not purport to be
appraisals or necessarily reflect the prices at which businesses or securities
actually may be sold. Analyses based upon forecasts of future results are not
necessarily indicative of actual future results, which may be significantly more
or less favorable than suggested by such analyses. Because such analyses are
inherently subject to uncertainty, being based upon numerous factors or events
beyond the control of the parties or their respective advisors, none of MBE,
USOP, AACC or any other person assumes responsibility if future results are
materially different from those forecast.
 
    AACC, as part of its investment banking business, is continually engaged in
the valuation of businesses in connection with mergers and acquisitions, as well
as initial and secondary offerings of securities and valuations for other
purposes. MBE selected AACC as its financial advisor because AACC is a
nationally recognized investment banking firm that has substantial experience in
transactions similar to the Merger.
 
    In the ordinary course of AACC's business, AACC and its affiliates may
actively trade securities of MBE and USOP for their own account and for the
accounts of customers and, accordingly, may at any time hold a long or short
position in such securities.
 
    Pursuant to the Engagement Letter, MBE engaged AACC to act as its financial
advisor in connection with the possible sale of MBE. Pursuant to the terms of
the Engagement Letter, MBE has paid AACC a $50,000 initial retainer fee, and an
additional $250,000 is payable by MBE to AACC since AACC has rendered the
fairness opinion. Pursuant to the terms of the Engagement Letter, MBE will pay
AACC, on the closing date, cash compensation equal to one percent (1.0%) of the
transaction value, less amounts paid previously under the Engagement Letter.
Further, MBE has agreed to reimburse AACC for its reasonable out-of-pocket
expenses, including attorneys' fees, and to indemnify AACC against certain
liabilities, including certain liabilities under the federal securities laws.
 
APPROVAL OF THE BOARD OF DIRECTORS OF U.S. OFFICE PRODUCTS COMPANY AND U.S.
  OFFICE PRODUCTS' REASONS FOR THE MERGER
 
    The Board of Directors of USOP unanimously approved the Merger Agreement.
The Merger does not require the approval of USOP's stockholders. In reaching its
conclusion to approve the Merger Agreement, the Board of Directors of USOP
considered many factors, including the following material factors:
 
    (i) the potential for MBE and USOP to provide an enhanced level of service
to the SOHO market by making available a broader range of business products and
services;
 
    (ii) MBE's revenue and financial condition including MBE's increases in
revenues during the first three fiscal quarters of its 1997 fiscal year, and as
compared to MBE's year-to-date earnings as of January 31, 1996; MBE's excess
cash; and MBE's low level of indebtedness;
 
    (iii) the ability of MBE franchisees to offer to their customers a larger
variety of office products and business services at the same favorable prices
that other large office supply competitors offer to the public;
 
    (iv) the expected accounting treatment of the Merger as a
pooling-of-interests (thereby avoiding the reduction in future earnings which
would result under purchase accounting);
 
                                       38
<PAGE>
    (v) the breadth of MBE's franchise network and the strategic benefits to
USOP of expanding its business to include the SOHO market through MBE's broad
distribution methods;
 
    (vi) the regulatory approvals required to consummate the Merger and the
favorable prospects for receiving all of such approvals;
 
    (vii) MBE's success as a franchisor;
 
    (viii) the greater purchasing power of USOP, which can benefit MBE
franchisees and their customers as well as MBE (and, thus, USOP and its
stockholders); and
 
    (ix) the name recognition of MBE.
 
    The foregoing discussion of the information and factors considered by the
USOP Board of Directors is not intended to be exhaustive. In view of the variety
of factors considered in connection with its evaluation of the Merger, the USOP
Board of Directors did not find it practicable to, and did not, quantify or
otherwise assign relative weights to the specific factors considered in reaching
its determination. In addition, individual members of the USOP Board of
Directors may have given different weights to different factors. Based on this
analysis, the USOP Board of Directors determined that the Merger is consistent
with and in furtherance of USOP's long-term business strategy and USOP's goal of
becoming the premier supplier of all office products and business services to
small and medium-sized companies.
 
   
    The factors considered by the USOP Board of Directors include
forward-looking statements relating to the opportunities that are expected to
result from the Merger. The actual results, performance or achievement of USOP
and MBE assuming consummation of the Merger could differ materially from the
anticipated results expressed above. Factors that could cause or contribute to
such differences include those discussed in "Risk Factors" beginning on page 16.
Neither the Company nor USOP undertakes any obligation to revise these
forward-looking statements to reflect any future events or circumstances.
    
 
SHARES TO BE VOTED BY DIRECTORS AND EXECUTIVE OFFICERS
 
   
    As of the Record Date, directors and executive officers of MBE had or shared
ownership of approximately 19% of the outstanding shares of MBE Common Stock. As
of the Record Date, directors and executive officers of USOP and their
affiliates were not beneficial owners of any of the outstanding shares of MBE
Common Stock.
    
 
FEDERAL INCOME TAX CONSEQUENCES
 
    Neither MBE, USOP nor Sub intends to secure a ruling from the Internal
Revenue Service (the "Service") with respect to the tax consequences of the
Merger. However, it is the opinion of O'Melveny & Myers LLP, counsel to MBE,
that, on the basis of facts, representations and assumptions set forth or
referred to in such opinion, (a) the Merger will constitute a reorganization
within the meaning of section 368(a) of the Code, and USOP, MBE and Sub will
each be a party to the reorganization within the meaning of section 368(b) of
the Code; (b) no gain or loss will be recognized by the holders of shares of MBE
Common Stock upon the receipt of shares of USOP Common Stock in exchange for
such shares of MBE Common Stock, except that a shareholder who receives cash in
lieu of a fractional share interest in USOP Common Stock will recognize gain or
loss equal to the difference between such cash and the basis allocated to the
fractional share interest; (c) the basis of the shares of USOP Common Stock
received by a holder of shares of MBE Common Stock (including any fractional
share interest treated as received) will be the same as the basis of the shares
of MBE Common Stock exchanged therefor; and (d) the holding period of the shares
of USOP Common Stock received by a holder of shares of MBE Common Stock
(including any fractional share interest treated as received) will include the
holding period of the shares of MBE Common Stock exchanged therefor, provided
such shares of MBE Common Stock were held as a capital asset at the effective
time of the Merger.

    TAX IMPLICATIONS TO MBE, USOP AND SUB
 
    No gain or loss will be recognized for federal income tax purposes by MBE,
USOP or Sub as a result of the Merger.
 
    TAX IMPLICATIONS TO DISSENTING SHAREHOLDERS
 
    Holders of MBE Common Stock who exercise their dissenters' rights with
respect to their shares will generally be treated as if such shares were
exchanged for the amount of cash received. Accordingly, dissenting shareholders
may recognize gain or loss as a result of the Merger. The nature and amount of
such gain or loss will depend on a number of factors, and shareholders
considering dissenting are strongly urged to consult their tax advisors as to
the particular tax consequences of doing so.
 
    OTHER TAX ASPECTS
 
    Apart from federal income taxes, no attempt has been made to determine any
tax that may be imposed on a shareholder by the country, state or jurisdiction
in which the holder resides or is a citizen. In addition to federal income
taxes, shareholders may be subject to other taxes, such as state or local income
taxes that may be imposed by various jurisdictions. Shareholders may also be
subject to income, intangible property, estate and inheritance taxes in their
state of domicile. Shareholders should consult their own tax advisors with
regard to state income, inheritance and estate taxes.
 
    THE FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE IS INTENDED TO PROVIDE
ONLY A SUMMARY, AND DOES NOT ADDRESS TAX CONSEQUENCES WHICH MAY VARY WITH, OR
ARE CONTINGENT ON, INDIVIDUAL CIRCUMSTANCES. MOREOVER, THIS DISCUSSION DOES NOT
ADDRESS ANY FOREIGN, STATE OR LOCAL TAX CONSEQUENCES OF THE DISPOSITION OF STOCK
IN MBE BEFORE THE MERGER OR THE DISPOSITION OF USOP STOCK AFTER THE MERGER.
ACCORDINGLY, EACH SHAREHOLDER IS STRONGLY URGED TO CONSULT WITH SUCH
SHAREHOLDER'S TAX ADVISOR TO DETERMINE THE PARTICULAR TAX CONSEQUENCES TO SUCH
SHAREHOLDER OF THE MERGER, INCLUDING THE APPLICABILITY AND EFFECT OF FOREIGN,
STATE, LOCAL AND OTHER TAX LAWS.
 
    ACCOUNTING TREATMENT
 
    The Merger is intended to qualify as a pooling-of-interests for accounting
purposes. Under this method of accounting, following completion of the Merger,
the financial conditions, results of operations and cash flows of USOP and MBE
will be reflected for accounting purposes as if MBE had always been a wholly
owned subsidiary of USOP. USOP has been advised by its independent accountants
that they believe the Merger will qualify as a pooling-of-interests under
generally accepted accounting principles. MBE has been advised by its
independent accountants that MBE meets the criteria for a pooling-of-interests.
USOP's obligation to complete the Merger is conditioned on, among other things,
(i) the receipt by USOP and MBE, at the Effective Time, of written confirmation
from their respective independent accountants of the advice described above, and
(ii) no events having occurred which would establish with reasonable certainty
that the Merger could not be treated as a pooling-of-interests.
 
    CONFLICTS OF INTEREST
 
   
    As of the Record Date, directors and executive officers of MBE beneficially
owned an aggregate of 2,196,994 shares of MBE Common Stock. Assuming the maximum
value of $29.00 (based on the Average Price of USOP Common Stock) per share of
MBE Common Stock is received by MBE shareholders in the Merger, the aggregate
dollar value of the shares of USOP Common Stock to be received in the Merger by
the executive officers and directors of MBE would be approximately $63,712,826.
    
 
                                       40
<PAGE>
    Certain of the major shareholders of MBE beneficially owning in the
aggregate approximately 34% of the shares of MBE Common Stock outstanding as of
the Record Date have entered into the Voting Agreements pursuant to which they
have agreed, among other things, to vote in favor of the Merger. See "--Voting
Agreements."
 
    Pursuant to the employment agreement dated September 18, 1996 between MBE
and James H. Amos, Jr., MBE's President and Chief Operating Officer, if Mr.
Amos' employment with MBE is terminated solely due to a sale or merger of MBE
prior to September 20, 1998, Mr. Amos is entitled to receive his annual base
salary of $231,000 over a 12-month period following his date of termination and
to retain his medical insurance coverage (under the terms of MBE's then-existing
medical insurance plan) for a period of one year following such termination.
USOP expects to negotiate employment arrangements with certain executive
officers of MBE on mutually agreeable terms which the Company anticipates will
be similar to those arrangements that USOP typically negotiates with executive
officers of other companies that it acquires.
 
    Pursuant to the Merger Agreement, USOP is required to indemnify and defend
(and to bear all associated costs and expenses) each officer and director of MBE
serving as such immediately prior to the Effective Time of the Merger from and
against any and all claims, damages and losses relating to or arising out of (i)
their performance of their respective Company duties prior to the Effective
Time, or (ii) the consummation of any of the transactions contemplated by the
Merger Agreement. In addition, USOP is required under the Merger Agreement to
cause the surviving corporation to provide, for a period of four years following
the Effective Time, officers' and directors' liability insurance in respect of
acts or omissions occurring prior to the Effective Time covering each person
covered by MBE's officers' and directors' liability insurance policy currently
in effect on terms with respect to coverage and amount that are no less
favorable than those provided in MBE's current policy. See "The Merger
Agreement--Certain Covenants."
 
    As of the Record Date, directors and executive officers of MBE held
outstanding options to purchase an aggregate of 1,302,007 shares of MBE Common
Stock. Pursuant to the Merger Agreement, each MBE stock option outstanding at
the Effective Time, including the options held by MBE directors and executive
officers, will be converted into an option to acquire the Option Conversion
Number of shares of USOP Common Stock at an exercise price per share equal to
the Adjusted Exercise Price. See "The Merger Agreement--Stock Options."
 
    In light of the foregoing, the directors and executive officers of MBE may
have personal interests in the Merger which are not identical to the interests
of other MBE shareholders.
 
    VOTING AGREEMENTS
 
    USOP has entered into the Voting Agreements with certain of the major
shareholders of MBE (and their affiliates) beneficially owning approximately 34%
of the outstanding shares of MBE Common Stock as of the Record Date. These
agreements, dated May 22, 1997, include (i) an agreement to vote or cause to be
voted the shares of MBE Common Stock owned or controlled by the shareholders
executing the agreements in favor of the Merger, (ii) an appointment of USOP as
proxy for and on behalf of such shareholders to vote their shares of MBE Common
Stock in favor of the Merger, and, (iii) except as provided in the affiliate
agreement to which each such shareholder is a party (see "--Certain Other
Agreements"), an agreement not to sell, transfer, pledge or otherwise dispose of
any of their shares of MBE Common Stock or any interest therein without the
written consent of USOP. The Voting Agreements were executed by Michael Dooling,
MBE's Chairman of the Board, Anthony W. DeSio, MBE's Vice Chairman of the Board
and Chief Executive Officer, and United Parcel Service of America, Inc. The
Voting Agreements terminate on the earlier of the Effective Time or the
termination of the Merger Agreement in accordance with its terms.
 
                                       41
<PAGE>
    CERTAIN OTHER AGREEMENTS
 
    Each of the affiliates of MBE has agreed not to transfer or otherwise
dispose of or reduce such affiliate's risk relating to (i) any shares of the MBE
Common Stock within 30 days prior to the Effective Time, and (ii) any shares of
USOP Common Stock acquired in the Merger until USOP has released results of
operations that reflect the combined post-Merger operations of USOP and MBE for
a minimum of 30 days, except for certain DE MINIMIS transactions as permitted
under the affiliate agreements. In addition, each of the affiliates has agreed
to certain federal securities law restrictions on the resale of USOP Common
Stock. See "--Federal Securities Law Consequences." The restrictions on resale
are intended to preserve the characterization of the Merger for federal income
tax purposes as a tax-free reorganization, to comply with the requirements for
pooling-of-interests accounting treatment and to comply with restrictions on the
resale of securities imposed by the federal securities laws.
 
    FEDERAL SECURITIES LAW CONSEQUENCES
 
    This Proxy Statement/Prospectus, unless appropriately amended or
supplemented, does not cover any resales by MBE shareholders of any shares of
USOP Common Stock that they receive in the Merger, and no person is authorized
to make any use of this Proxy Statement/Prospectus in connection with any such
resale.
 
    All shares of USOP Common Stock received by MBE shareholders in the Merger
will be freely transferable, except that persons who are deemed to be
"affiliates" (as such term is defined for purposes of the pooling-of-interests
requirements and the Securities Act) of MBE prior to the Merger may resell
shares they receive only in transactions permitted by the resale provisions of
Rule 145 promulgated under the Securities Act, or as otherwise permitted under
the Securities Act. Persons who may be deemed to be affiliates of MBE generally
include individuals or entities who or that control, are controlled by, or are
under common control with, MBE and may include certain officers, directors and
principal shareholders of MBE. In addition, except for certain permitted DE
MINIMIS transactions (subject to compliance with federal securities laws), such
affiliates will not be permitted to sell shares they receive in the Merger until
USOP has released results of operations that reflect the combined post-Merger
operations of USOP and MBE for a minimum of 30 days. See "--Certain Other
Agreements."
 
    GOVERNMENTAL AND REGULATORY APPROVAL
 
    Under the HSR Act, and the rules promulgated thereunder by the FTC, the
Merger may not be completed until notifications have been given and certain
information has been furnished to the FTC and the Antitrust Division and
specified waiting period requirements have been satisfied. USOP and MBE filed
notification and report forms under the HSR Act with the FTC and the Antitrust
Division on June 20, 1997. The FTC and the Antitrust Division granted early
termination of the HSR waiting period on July 3, 1997. Thus, the waiting period
requirements of the HSR Act have been satisfied. Nevertheless, at any time
before or after consummation of the Merger, the FTC, the Antitrust Division or
state attorneys' general could take such action under the antitrust laws as they
deem necessary or desirable in the public interest, including seeking to enjoin
the consummation of the Merger. Private parties may also seek to take legal
action under the antitrust laws under certain circumstances.
 
    Based on the information available to them, USOP and MBE believe that the
Merger can be effected in compliance with federal and state antitrust laws.
However, there can be no assurance that a challenge to the consummation of the
Merger on antitrust grounds will not be made or that, if such challenge were
made, USOP and MBE would prevail or would not be required to accept certain
conditions, including the divestitures of certain assets, in order to consummate
the Merger.
 
                                       42
<PAGE>
    DISSENTERS' RIGHTS OF APPRAISAL
 
    The rights of shareholders of MBE to dissent from approval of the Merger and
demand payment for their shares are governed by Chapter 13 of the CGCL, the full
text of which is reprinted as Appendix III to this Proxy Statement/Prospectus.
The summary of these rights set forth below is not intended to be complete and
is qualified in its entirety by reference to Appendix III.
 
    Under the CGCL, shareholders of MBE will not have any dissenters' rights
with respect to the Merger unless demands for payment are duly filed with
respect to five percent or more of the outstanding shares of MBE Common Stock.
If the holders of five percent or more of the outstanding shares of MBE Common
Stock duly file demands for payment and fully comply with Chapter 13 of the
CGCL, they will have dissenters' rights to be paid in cash the fair market value
of their shares.
 
    Under the CGCL, "fair market value" is determined as of the day before the
first announcement of the terms of the Merger Agreement, excluding any
appreciation or depreciation as a consequence of the Merger. If the parties are
unable to agree on a fair market value, the dissenting shareholder may request
the Superior Court for the County of San Diego to determine the fair market
value of the shares. The court's decision would be subject to appellate review.
 
    The terms of the Merger Agreement were publicly announced on May 22, 1997.
On May 21, 1997, the last trading day prior to the public announcement of the
terms of the Merger, the high and low sales prices for MBE Common Stock were
$19.63 and $19.13, respectively.
 
    DISSENTERS' RIGHTS CANNOT BE VALIDLY EXERCISED BY PERSONS OTHER THAN
SHAREHOLDERS OF RECORD REGARDLESS OF THE BENEFICIAL OWNERSHIP OF THE SHARES.
Persons who are beneficial owners of shares held of record by another person,
such as a broker, a bank or a nominee, should instruct the record holder to
follow the procedures outlined below if such beneficial owners wish to dissent
from the approval of the Merger.
 
    As described more fully below, in order to perfect their dissenters' rights,
shareholders of record must: (i) make written demand for the purchase of their
dissenting shares to MBE or its transfer agent on or before the date of the
Special Meeting; (ii) vote their dissenting shares against approval of the
Merger; and (iii) within 30 days after the mailing to shareholders by MBE of
notice of approval of the Merger, submit the certificates representing their
dissenting shares to MBE, or its transfer agent, for notation thereon that they
represent dissenting shares. Failure to follow any of these procedures may
result in the loss of statutory dissenters' rights.
 
    DEMAND FOR PURCHASE
 
    Dissenting shareholders of MBE must submit to MBE at its principal office,
6060 Cornerstone Court West, San Diego, California 92121, or to its transfer
agent, Chase Mellon Shareholder Services, 400 South Hope Street, 4th floor, Los
Angeles, California 90071, a written demand that MBE purchase for cash those
shares with respect to which they wish to act as dissenting shareholders.
 
    The notice must state the number of shares held of record which the
shareholder demands to be purchased and the amount claimed to be the "fair
market value" of those shares. That statement of fair market value will
constitute an offer by the dissenting shareholder to sell such shares at that
price. SUCH DEMAND WILL NOT BE EFFECTIVE UNLESS IT IS RECEIVED BY NOT LATER THAN
THE DATE OF THE SPECIAL MEETING.
 
    Dissenting shareholders may not withdraw their demand for payment without
the consent of the Company Board. The rights of dissenting shareholders to
demand payment terminate if the Merger is abandoned (although dissenting
shareholders are entitled upon demand to reimbursement of expenses incurred in a
good faith assertion of their dissenters' rights), or if the shares are
transferred prior to submission for endorsement as dissenting shares.
 
    No shareholder who has a right to demand payment of cash for such
shareholder's shares and who in fact makes such a demand will have any right to
attack the validity of the Merger or have the Merger set
 
                                       43
<PAGE>
aside or rescinded, except in an action to test whether MBE has received the
number of shares required to approve the Merger. Any shareholder who does not
demand payment of cash for such shareholder's shares and who institutes an
action to attack the validity of the Merger or to have the Merger set aside or
rescinded would not thereafter have any right to demand payment of cash pursuant
to the exercise of dissenters' rights.
 
    VOTE AGAINST APPROVAL OF THE MERGER
 
    Dissenting shareholders must vote their dissenting shares against approval
of the Merger. Record shareholders may vote part of the shares that they are
entitled to vote in favor of the Merger or abstain from voting a part of such
shares without jeopardizing their dissenters' rights as to other shares;
however, if record shareholders vote part of the shares they are entitled to
vote in favor of the Merger and fail to specify the number of shares they are so
voting, it is conclusively presumed under California law that their approving
vote is with respect to all shares that they are entitled to vote. Voting
against the Merger will not of itself, absent compliance with the provisions of
Chapter 13 of the CGCL summarized herein, satisfy the requirements of the CGCL
for exercise and perfection of dissenters' rights. However, any shareholder
desiring to exercise dissenters' rights must vote against approval of the
Merger.
 
    NOTICE OF APPROVAL
 
    If shareholders have a right to require MBE to purchase their shares for
cash under the dissenters' rights provisions of the CGCL, MBE will mail to each
such shareholder a notice of approval of the Merger within ten days after the
date of shareholder approval, stating the price determined by it to represent
the "fair market value" of the dissenting shares. The statement of price will
constitute an offer to purchase any dissenting shares at that price.
 
    SUBMISSION OF STOCK CERTIFICATES
 
    Within 30 days after the mailing of the notice of approval of the business
combination, dissenting shareholders must submit to MBE or its transfer agent,
at the address set forth above, certificates representing the dissenting shares
to be purchased, to be stamped or endorsed with a statement that the shares are
dissenting shares or are to be exchanged for certificates of appropriate
denomination so stamped or endorsed. The notice of approval of the Merger will
specify the date by which the submission of certificates for endorsement must be
made and a submission made after that date will not be effective for any
purpose.
 
    PURCHASE OF DISSENTING SHARES
 
    If a dissenting shareholder and MBE agree that the shares are dissenting
shares and agree upon the price of the shares, MBE will, upon surrender of the
certificates, make payment of that amount (plus interest thereon at the legal
rate on judgments from the date of such agreement) within 30 days after that
agreement. Any agreement between dissenting shareholders and MBE fixing the
"fair market value" of any dissenting shares must be filed with the Secretary of
MBE.
 
    If MBE denies that the shares are dissenting shares, or MBE and a dissenting
shareholder fail to agree upon the "fair market value" of the shares, the
dissenting shareholder may, within six months after the date on which notice of
approval of the Merger was mailed to the shareholder, but not thereafter, file a
complaint (or intervene in a pending action, if any) in the Superior Court for
San Diego County, State of California, requesting that the Superior Court
determine whether the shares are dissenting shares and the "fair market value"
of such dissenting shares. The Superior Court may appoint one or more impartial
appraisers to determine the "fair market value" per share of the dissenting
shares. The costs of the action, including reasonable compensation to the
appraisers to be fixed by the court, will be assessed or apportioned as the
Superior Court considers equitable, but if the "fair market value" is determined
to
 
                                       44
<PAGE>
exceed the price offered to the shareholder by MBE, then MBE will be required to
pay such costs (including, in the discretion of the Superior Court, attorneys'
fees, fees of expert witnesses and interest at the legal rate on judgments, if
such "fair market value" is determined to exceed 125% of the price offered by
MBE). A dissenting shareholder must bring this action within six months after
the date on which notice of approval of the Merger was mailed to the shareholder
whether or not the corporation responds within such time to the shareholder's
written demand that MBE purchase for cash shares voted against the approval of
the Merger.
 
    The Merger Agreement entitles USOP to terminate the Merger Agreement if
holders of more than five percent of the outstanding shares of MBE Common Stock
vote against approval of the Merger. USOP expects that it will not terminate the
Merger Agreement for this reason unless the percentage of shares of MBE Common
Stock voted against the Merger makes it unlikely that the Merger could be
accounted for under the pooling-of-interests method of accounting. In general,
the Merger could not be accounted for as a pooling-of-interests if more than 10%
of the shares of MBE Common Stock were dissenting shares that had to be
purchased for cash pursuant to Chapter 13 of the CGCL.

                              THE MERGER AGREEMENT
 
    THE FOLLOWING IS A SUMMARY DESCRIPTION OF CERTAIN TERMS OF THE MERGER
AGREEMENT, WHICH IS ATTACHED AS APPENDIX I TO THIS PROXY STATEMENT/PROSPECTUS
AND IS INCORPORATED HEREIN BY REFERENCE. THIS DESCRIPTION CONTAINS THE MATERIAL
TERMS OF THE MERGER AGREEMENT BUT IS NOT COMPLETE AND IS QUALIFIED BY REFERENCE
TO THE MERGER AGREEMENT. MBE SHAREHOLDERS ARE URGED TO READ THE MERGER AGREEMENT
CAREFULLY IN ITS ENTIRETY. CAPITALIZED TERMS USED BUT NOT DEFINED IN THIS
SUMMARY HAVE THE MEANINGS GIVEN TO THEM IN THE MERGER AGREEMENT.
 
    GENERAL
 
    The Merger Agreement provides that, upon the satisfaction or waiver of
specified conditions, MBE and USOP will consummate the Merger, in which Sub will
merge with and into MBE, with MBE as the Surviving Corporation. Upon the
effectiveness of the Merger, the separate existence of Sub will cease and USOP
will own directly 100% of the outstanding capital stock of MBE. The closing of
the Merger is expected to take place as soon as practicable after the
satisfaction or waiver of the conditions set forth in the Merger Agreement,
including approval of the Merger Agreement by MBE shareholders.
 
    Upon and after the Merger, the MBE Charter will be the Articles of
Incorporation of the Surviving Corporation and the Bylaws of Sub will be the
Bylaws of the Surviving Corporation. The initial directors of the Surviving
Corporation will be the directors of Sub immediately prior to the Merger and the
initial officers of the Surviving Corporation will be the officers of MBE
immediately prior to the Merger, with the addition of Mark D. Director, Chief
Administrative Officer, and General Counsel and Secretary of USOP, as an
Assistant Secretary of MBE, and except that Mr. DeSio will not serve as the
Chief Executive Officer of the Surviving Corporation.
 
    CONVERSION OF SHARES
 
   
    The Merger Agreement provides that at the Effective Time each share of MBE
Common Stock issued and outstanding as of the Effective Time (other than shares
that are held by dissenting shareholders) will be converted into the right to
receive 1.5 shares of USOP Common Stock, subject to adjustment under certain
circumstances in the event that the Average Price of USOP Common Stock (as
defined above) is less than $15.33 or more than $19.33. If the Average Price of
USOP Common Stock is more than $19.33, the Exchange Ratio will automatically be
adjusted to be equal to 1.5 times the quotient of $19.33 divided by the Average
Price of USOP Common Stock. If the Average Price of USOP Common Stock is less
than $15.33 and if MBE elects to terminate the Merger Agreement, USOP has the
option, but not the obligation, to adjust the Exchange Ratio to be equal to 1.5
times the quotient of $15.33 divided by the Average Price of USOP Common Stock.
If USOP adjusts the Exchange Ratio as described, MBE must accept the adjustment
and, assuming all other conditions to the Merger are satisfied or waived,
proceed with the Merger. If the Average Price of USOP Common Stock is less than
$15.33 and MBE does not elect to terminate the Merger Agreement, the Exchange
Ratio will not change. See "Risk Factors -- Special Considerations with Respect
to the Merger -- Risks Associated with Exchange Ratio" and " -- Merger Approval
Confers Discretion on Company Board to Terminate or Proceed with Merger if
Average Price is Below $15.33." Each of the shareholders of MBE Common Stock who
would be entitled to receive a fractional share of USOP Common Stock upon
surrender of such shareholder's shares of MBE Common Stock will receive, in lieu
thereof, cash in an amount equal to the value of such fractional share.
    
 
    The Merger Agreement also provides that at the Effective Time each share of
MBE Common Stock owned by USOP, Sub or any other subsidiary of USOP will
automatically be canceled or retired without conversion and without payment of
any consideration. As of the date of this Proxy Statement/Prospectus, none of
USOP, Sub or any other subsidiary of USOP owned any shares of MBE Common Stock.
 
    As of the Effective Time, shares of MBE Common Stock will no longer be
outstanding and will automatically be canceled and retired and shall cease to
exist. Each certificate previously representing shares of MBE Common Stock will
represent only the right to receive shares of USOP Common Stock into
 
                                       46
<PAGE>
which the MBE Common Stock was converted in the Merger. No fractional shares of
USOP Common Stock will be issued in the Merger. Instead of fractional shares,
holders of MBE Common Stock will receive a cash payment equal to the fraction of
USOP Common Stock that would otherwise be issued, multiplied by the Average
Price of USOP Common Stock.
 
    STOCK OPTIONS
 
    Pursuant to the Merger Agreement and the terms of the outstanding options
under MBE's Restated 1985 Stock Option Plan, 1995 Employee Stock Option Plan and
1995 Stock Option Plan for Non-Employee Directors, each option outstanding
immediately prior to the Effective Time, whether or not exercisable, will be
converted as of the Effective Time into the right to purchase from USOP the
Option Conversion Number of shares of USOP Common Stock at the Adjusted Exercise
Price (each, an "Adjusted Option"). Each Adjusted Option will have substantially
the same terms as the MBE stock option to which it is related. No fractional
shares of USOP Common Stock will be issued on exercise of an Adjusted Option. A
holder who exercises an Adjusted Option and would otherwise be entitled to
receive a fractional share will receive instead an amount of cash equal to the
fractional part of a share of USOP Common Stock multiplied by the closing price
of USOP Common Stock on the Nasdaq National Market System on the trading date
immediately preceding the exercise date. USOP has agreed to take such actions as
are necessary for the conversion of MBE stock options into Adjusted Options. See
"The Merger -- Stock Options."

    The Merger Agreement contains representations and warranties of MBE relating
to, among other things, (a) proper organization, power and qualification, (b)
capital structure, (c) the authorization, performance and enforceability of the

    CERTAIN COVENANTS
 
    CONDUCT OF BUSINESS
 
    Under the terms of the Merger Agreement, MBE has agreed that, during the
period from the date of the Merger Agreement until the Effective Time, it will
and it will cause its subsidiaries to, conduct their businesses in the ordinary
course. In particular, MBE has agreed that, other than as set forth in the
Merger Agreement or with USOP's consent, it will not and it will not permit any
of its subsidiaries to: (a) declare, set aside or pay any dividends on, or make
any other distributions in respect of, any of its capital stock, other than
distributions or dividends by any wholly owned subsidiary of MBE to its parent,
(b) split, combine or reclassify any of its capital stock or issue or authorize
the issuance of securities in respect of, or
 
                                       47
<PAGE>
in lieu of or in substitution for, shares of its capital stock, (c) purchase,
redeem or otherwise reacquire shares of capital stock or other securities of MBE
or any of its subsidiaries or any rights, warrants or options to acquire such
shares or securities, (d) other than the issuance upon the exercise of
outstanding options to purchase MBE Common Stock or pursuant to employment
agreements existing on the date of the Merger Agreement, issue, deliver, sell,
award, pledge, dispose of or otherwise encumber or authorize or propose the
issuance, delivery, grant, sale, award, pledge or other encumbrance or
authorization of, any shares of capital stock or any voting securities or
securities convertible into, or any rights, warrants or options to acquire, any

    NO INCONSISTENT ACTIVITIES
 
    MBE has agreed that it will (a) terminate existing discussions with other
parties regarding the potential acquisition of MBE or any other transaction that
would be inconsistent with the Merger Agreement and (b) not, and will not permit
its subsidiaries to, nor authorize or permit any officer, director or employee
or investment banker, attorney or other representative or advisor to solicit or
initiate or encourage the submission of, any Takeover Proposal (as defined
below), or participate in any discussions or negotiations regarding, or furnish
to any person any information with respect to, or take any other action to
facilitate any inquiries or the making of any proposal that constitutes, or may
reasonably be expected to lead to, any Takeover Proposal. The foregoing
requirements do not prohibit the Company Board from furnishing information to or
entering into discussions or negotiations with any person or entity that makes
an unsolicited bona fide proposal to acquire MBE, but only to the extent that
(i) the Company Board determines in good faith, with written advice from outside
counsel, that such action is required by its fiduciary duties to MBE's
shareholders, (ii) the Company Board determines in good faith, with written
advice of its financial advisors, that the proposal is financially superior to
the transaction contemplated by the Merger Agreement and the party making the
proposal has demonstrated that the funds necessary for its proposal are
reasonably likely to be available (a "Superior Proposal"), and (iii) prior to
furnishing such information to, or entering into discussions or negotiations
with, such person or entity, MBE provides written notice to USOP to the effect
that it is furnishing the information to or entering into discussions or
negotiations with the person or entity making such proposal and receives an
executed confidentiality agreement from such person or entity. MBE agrees to
provide notice to USOP within 24 hours of any
 
                                       48
<PAGE>
inquiries, offers or proposals it receives with respect to a Takeover Proposal
and to keep USOP informed of the status of any such inquiry, offer or proposal.
In addition, MBE agrees to give USOP five business days' advance notice of any
agreement to be entered into with, or any information to be supplied to, any
person making such inquiry, offer or proposal. The Merger Agreement defines
"Takeover Proposal" as any written proposal for a merger, consolidation,
purchase of assets, tender offer or other business combination involving MBE or
any of its subsidiaries, or any proposal or offer to acquire in any manner,
directly or indirectly, an equity interest in, any voting securities of, or a
substantial portion of the assets of, the Company or any of its subsidiaries,
other than the transactions contemplated by the Merger Agreement. The Merger
Agreement does not prohibit MBE or the Company Board from disclosing to its
shareholders a position as contemplated by Rule 14d-9 and Rule 14e-2(a) under
the Exchange Act with respect to a Takeover Proposal by means of a tender offer.
 
    DIRECTOR AND OFFICER INDEMNIFICATION
 
    The Merger Agreement provides that the articles of incorporation and bylaws
of the Surviving Corporation will contain provisions for indemnification and
exculpation of MBE directors and officers that are currently contained in MBE's
articles of incorporation and bylaws and that the provisions will not be amended
or repealed in a manner adverse to the individuals who are, prior to the
Effective Time, directors, officers, employees or agents of MBE, for six years
following the Effective Time. USOP guarantees for the benefit of MBE's directors
and officers the indemnification arrangements set forth in the articles of
incorporation and bylaws as well as in any indemnification agreements. The
amount of USOP's guarantee obligations cannot exceed the amount permitted by its
credit agreement which, as of the date of this Proxy Statement/Prospectus is $40
million. The successor and assigns of USOP and the Surviving Corporation are
bound by these provisions.
 
    In addition to the foregoing, USOP agrees to indemnify and defend (and bear
all costs and expenses associated therewith) each officer and director of MBE
serving as such immediately prior to the Effective Time for and against any
claims, damages or losses relating to or arising out of (a) their performance of
their respective Company duties before the Effective Time or (b) the
consummation of any of the transactions contemplated by the Merger Agreement.
USOP also agrees to provide for four years officers' and directors' liability
insurance covering such officers and directors for acts and omissions occurring
prior to the Effective Time in amounts and on terms no less favorable than those
provided for by MBE's insurance policy in place prior to the Effective Time,
provided that USOP's aggregate cost for such coverage may not exceed an amount
equal to four times the premium cost for MBE's insurance policy for the year
ended April 30, 1997.

Time, whether before or after approval by the shareholders of MBE (except as
otherwise indicated below) (a) by mutual written consent of USOP and MBE; (b) by
USOP or MBE (so long as the party seeking to terminate is not then in material
breach of any representation, warranty, covenant or other agreement contained in
the Merger Agreement), upon a breach of any representation, warranty, covenant
or agreement on the part of the other party to the Merger Agreement or if any
representation or warranty of the other party has become untrue, in either case
such that such breach or untruth would be incapable of being cured or corrected
by November 30, 1997; provided, that a willful breach is deemed to be incapable
of being cured or corrected by such date; (c) by USOP or MBE if any governmental
entity issues an order, decree, injunction or ruling or takes any other action
permanently enjoining, restraining or otherwise prohibiting the consummation of
the Merger and such order or other action has become final and nonappealable;
(d) by USOP or MBE, if the Merger has not occurred by November 30, 1997, unless
the failure to consummate is the result of a breach of a covenant in the Merger
Agreement or a willful and material breach of any representation or warranty by
the party seeking to terminate; (e) by USOP or MBE (provided that if MBE is the
terminating party, it is not in material breach of any of its obligations under
the Merger Agreement), if the approval of MBE shareholders required for the
consummation of the Merger has not been obtained because of a failure to receive
the required vote at a duly held meeting of the MBE shareholders; (f) by MBE,
prior to approval of the Merger by its shareholders and upon five business days'
prior notice to USOP, if, as a result of a Superior Proposal by a party other
than USOP or its affiliates, the Company Board determines that its
    
 
                                       50
<PAGE>
   
fiduciary duties to the MBE shareholders require it to accept the Superior
Proposal, provided that (i) MBE has determined, after receiving written advice
of outside counsel, that its fiduciary duties require acceptance of the Superior
Proposal, after giving effect to concessions offered by USOP described in the
following clause (ii), and (ii) , prior to accepting the Superior Proposal and
terminating the Merger Agreement, MBE has offered USOP an opportunity (for a
period of at least five business days following receipt of the offer) to amend
the Merger Agreement to provide for terms substantially similar to those
included in the Superior Proposal; (g) by USOP, if the Company Board (or any
committee thereof) (i) withdraws or modifies adversely its approval and
recommendation of the Merger or the Merger Agreement, (ii) , within 10 days
after USOP's request, fails to reaffirm such approval or recommendation, (iii)
approves or recommends any Takeover Proposal, other than with USOP or its
affiliate, or a tender offer or exchange offer for 15% or more is commenced and
the Company Board fails to recommend against such tender offer or exchange
offer, (iv) resolves to take any action described in this clause (g), or (v)
fails to call and hold a meeting of MBE shareholders within 40 days after the
Commission declares the Registration Statement effective; or (h) by MBE, if the
Average Price of USOP Common Stock is less than $15.33, unless USOP, within
three days after receipt of MBE's written election to terminate, elects to
adjust the Exchange Ratio to be equal to 1.5 times the quotient of $15.33
divided by the Average Price of USOP Common Stock.
    
 
   
    MBE will be required to pay a cash termination fee to USOP if (a) MBE
terminates the Merger Agreement to accept a Superior Proposal in accordance with
the terms of the Merger Agreement described in clause (f) of the preceding
paragraph or if USOP terminates the Merger Agreement for one of the reasons
described in clause (g) of the preceding paragraph or because of MBE's material
breach of its covenant not to pursue an alternative Takeover Proposal, (b) MBE
or USOP terminates the Merger Agreement because the Merger is not completed by
November 30, 1997 and within six months after such termination MBE enters into a
definitive agreement with another entity (other than USOP or an affiliate) in
respect of a Takeover Proposal or (c) MBE's shareholders do not approve the
Merger and at the time of termination of the Merger Agreement or prior to the
Special Meeting, there has been a Takeover Proposal (whether or not the Takeover
Proposal has been rejected or withdrawn prior to such termination or the
meeting) and MBE enters into a definitive agreement with another entity within
one year of termination. The cash termination fee will equal (i) $9,569,924 or
(ii), if greater and if MBE enters into a definitive agreement with respect to a
Takeover Proposal within six months following the termination of the Merger
Agreement for one of the reasons described in clause (d), (e), (f) or (g) in the
preceding paragraph, then 3% of the product of the number of outstanding shares
of MBE Common Stock on a fully diluted basis on the date such definitive
agreement is executed, multiplied by the value per share of MBE Common Stock of
the consideration to be paid pursuant to such Takeover Proposal. If the Merger
Agreement is terminated as described in this paragraph, MBE will be required to
pay USOP at the time of such termination, in addition to any other cash
termination fee paid or payable, an amount in cash equal to $3,082,175 to cover
the expenses of USOP and Sub incurred in connection with the Merger. In
addition, if the Merger Agreement is terminated because MBE shareholder approval
is not received and at the time of such termination or prior to the Special
Meeting there has been a Takeover Proposal, MBE will be required to pay to USOP
the $3,082,175 referenced in the preceding sentence plus cash in an amount equal
to $1,541,087 (which amount would be deducted from any cash termination fee that
the Company would be required to pay if it enters into a definitive agreement
respecting a Takeover Proposal within one year following the termination of the
Merger Agreement for failure of the Company's shareholders to approve the
Merger).
    
 
    FEES AND EXPENSES
 
    In addition to the expenses described above under the heading "--
Termination," whether or not the Merger is completed, each party will bear its
own expenses incurred in connection with the Merger, other than costs relating
to the preparation of the Proxy Statement/Prospectus, which will be shared
equally by USOP and MBE.

<PAGE>
    AMENDMENT AND WAIVER
 
    The Merger Agreement may be amended by the parties at any time prior to
approval by MBE shareholders, but after such approval, there can be no amendment
that by law would require further approval by the shareholders without further
shareholder approval. Any amendment must be in writing and signed by both
parties.
 
    At any time prior to the Effective Time, the parties may (a) extend the time
for performance of any of the obligations or acts of the other parties, (b)
waive any inaccuracies in the representations and warranties contained in the
Merger Agreement or in any document delivered pursuant to the Merger Agreement
or (c) subject to the requirements described in the preceding paragraph, waive
compliance with any of the agreements or conditions contained in the Merger
Agreement. Any agreement regarding extension or waiver must be in writing and
signed by the party granting such extension or waiver.

    (k) Adjustment to reflect the federal income taxes for certain acquisitions
accounted for under the pooling-of-interest market which were taxed as
subchapter S corporations as if these companies had been subject to taxation as
C corporations. As a result of being subchapter S corporations, any tax
liabilities prior to acquisitions were the responsibility of the individual
company stockholders.

Directors of USOP as shares of one or more classes or series. Subject to the
provisions of the USOP Charter and limitations prescribed by law, the Board of
Directors of USOP is expressly authorized to adopt resolutions to issue the
shares, to fix the number of shares and to change the number of shares
constituting any series, and to provide for or change the voting powers,
designations, preferences and relative, participating, optional or other special
rights, qualifications, limitations or restrictions thereof, including dividend
rights (including whether dividends are cumulative), dividend rates, terms of
redemption (including sinking fund provisions), redemption prices, conversion
rights and liquidation preferences of the shares constituting any class or
series of USOP Preferred Stock, in each case without any further action or vote
by the stockholders. USOP has no current plans to issue any shares of USOP
Preferred Stock of any class or series.
 
    One of the effects of undesignated USOP Preferred Stock may be to enable the
Board of Directors of USOP to render more difficult or to discourage an attempt
to obtain control of USOP by means of a tender offer, proxy context, merger or
otherwise, and thereby to protect the continuity of USOP's management. The
issuance of shares of USOP Preferred Stock pursuant to the USOP Board of
Directors' authority described above may adversely affect the rights of the
holders of USOP Common Stock. For example, USOP Preferred Stock issued by USOP
may rank prior to USOP Common Stock as to dividend rights, liquidation
preference or both, may have full or limited voting rights and may be
convertible into shares of USOP Common Stock. Accordingly, the issuance of
shares of USOP Preferred Stock may discourage bids for the USOP Common Stock or
may otherwise adversely affect the market price of USOP Common Stock.

                     COMPARATIVE RIGHTS OF STOCKHOLDERS OF
                    U.S. OFFICE PRODUCTS AND MAIL BOXES ETC.
 
    The rights of USOP stockholders are currently governed by the DGCL, the USOP
Charter and the USOP Bylaws. The rights of MBE shareholders are currently
governed by the CGCL, the MBE Charter and the MBE Bylaws. Upon consummation of
the Merger, the rights of MBE shareholders who become stockholders of USOP in
the Merger will be governed by the DGCL, the USOP Charter and the USOP Bylaws.
 
    There follows a summary of the differences between the rights of
shareholders of MBE and USOP. This summary does not purport to be complete and
is qualified in its entirety by reference to the DGCL, the CGCL, the USOP
Charter, the USOP Bylaws, the MBE Charter and the MBE Bylaws.
 
AUTHORIZED CAPITAL
 
    The authorized capital stock of MBE is 40,000,000 shares of MBE Common Stock
and 10,000,000 shares of preferred stock, each having no par value per share.
The authorized capital stock of USOP is 500,000,000 shares of USOP Common Stock
and 500,000 shares of preferred stock, each having a par value $.001 per share.
 
SIZE OF BOARD OF DIRECTORS
 
    Under the CGCL, although changes in the number of directors must normally be
approved by the shareholders, a corporation's articles of incorporation or
bylaws may include a provision that sets forth a permissible range in the number
of directors within which the board of directors may fix the exact number of
directors without shareholder approval. The range must be such that the highest
number is equal to one less than twice the lowest number. The MBE Bylaws provide
that the Company Board shall consist of not less than five nor more than nine
directors, with the exact number to be set from time to time.
 
    Under the DGCL, a corporation's certificate of incorporation may authorize
the board of directors to change the authorized number of directors by amendment
to the bylaws or in the manner provided in the bylaws, and there is no
requirement that the board's discretion be limited within a permissible range.
The USOP Bylaws provide that the size of the board of directors is to be
established by resolution of a majority of the board of directors.
 
CUMULATIVE VOTING
 
    The CGCL allows shareholders to cumulate votes in the election of directors,
subject to the corporation's articles of incorporation and bylaws, as long as
the candidates have been nominated and any one shareholder has given notice of
his or her intention to cumulate votes. The MBE Bylaws do not alter the right
provided by the CGCL. The DGCL allows cumulative voting when the corporation's
certificate of incorporation provides for it; however, the USOP Charter does not
so provide.
 
CLASSIFIED BOARD OF DIRECTORS
 
    A classified board is one on which a certain number, but not all, of the
directors are elected on a rotating basis each year. Under the CGCL, directors
generally are elected annually; however, corporations that (i) have stock
designated as qualified for trading as a national market system security on
Nasdaq and have 800 or more shareholders of record, or (ii) have their stock
listed on the American Stock Exchange or the New York Stock Exchange are
permitted to designate a classified board (of two or three classes) by
 
                                       63
<PAGE>
adopting amendments to their articles or bylaws, which amendments must be
approved by a majority of the outstanding shares. The DGCL permits, but does not
require, a classified board of directors, with staggered terms under which
one-half or one-third of the directors are elected for terms of two or three
years, respectively. This method of electing directors makes a change in the
composition of the board of directors, and a potential change in control of a
corporation, a lengthier and more difficult process. Neither the USOP Bylaws nor
the MBE Bylaws currently provides for a classified board of directors.
 
REMOVAL OF DIRECTORS
 
    Under the CGCL, the entire board of directors may be removed, with or
without cause, with the approval of a majority of the outstanding shares
entitled to vote. However, where individual directors are candidates for removal
or the board is classified, no director may be removed if the number of votes
cast against removal would be sufficient to elect the director under cumulative
voting (regardless of whether shares may otherwise be voted cumulatively) and
certain other requirements are met. Under the DGCL, directors on an unclassified
board may be removed with or without cause by a majority of the outstanding
shares entitled to vote.
 
WRITTEN CONSENT OF STOCKHOLDERS
 
    Both the CGCL and DGCL provide that the stockholders of a corporation may
take action by written consent without a meeting, unless the corporation's
certificate or articles of incorporation provide otherwise. The MBE Bylaws do
not contain any provisions prohibiting actions by written consent, although they
do require unanimous consent for certain elections of directors. The USOP Bylaws
allow the stockholders to take any action by written consent of the percentage
of the vote required for the action to be taken at a meeting of stockholders.
 
POWER TO CALL SPECIAL STOCKHOLDERS' MEETINGS
 
    Under the CGCL, a special meeting of shareholders may be called by the board
of directors, the chairman of the board, the president, the holders of shares
entitled to cast not less than 10 percent of the votes at such meeting and such
additional persons as are authorized by the articles of incorporation or the
bylaws. Under the DGCL, a special meeting of stockholders may be called by the
board of directors or by any other person authorized to do so in the certificate
of incorporation or the bylaws. The MBE Bylaws do not grant any person other
than those listed in the CGCL the right to call a special meeting of
shareholders. The USOP Bylaws authorize the board of directors, the chairman of
the board, the president, and stockholders holding together at least 25% of the
shares entitled to vote to call a special meeting of the stockholders.
 
STOCKHOLDER APPROVAL OF CERTAIN BUSINESS COMBINATIONS
 
    A number of states (but not California) have adopted special laws designed
to make certain kinds of "unfriendly" corporate takeovers, or other transactions
involving a corporation and one or more of its significant stockholders, more
difficult. Under Section 203 of the DGCL, certain "business combinations" with
"interested stockholders" of Delaware corporations are subject to a three-year
moratorium unless specified conditions are met. An "interested stockholder" is
defined as a person who, together with any affiliates and/or associates of such
person, beneficially owns, directly or indirectly, 15% or more of the
outstanding voting shares of a Delaware corporation. Section 203 prohibits
certain business combinations (defined broadly to include mergers,
consolidations, sales or other dispositions of assets having an aggregate value
in excess of 10% of the consolidated assets of the corporation, and certain
transactions that would increase the interested stockholder's proportionate
share ownership in the corporation) between an interested stockholder and a
corporation for a period of three years after the date the interested
stockholder acquired its stock, unless (i) the business combination or the
transaction which resulted in the stockholder becoming an interested stockholder
is approved by the corporation's board of
 
                                       64
<PAGE>
directors prior to the date the interested stockholder acquired shares, (ii) the
interested stockholder acquired at least 85% of the voting stock of the
corporation in the transaction in which it become an interested stockholder, or
(iii) the business combination is approved by a majority of the board of
directors and by the affirmative vote of two-thirds of the votes entitled to be
cast by disinterested stockholders at an annual or special meeting. The
provisions of Section 203 apply to USOP because USOP has not "opted out" of
Section 203.
 
FILLING VACANCIES ON THE BOARD OF DIRECTORS
 
    Under the CGCL, unless otherwise provided in a corporation's articles of
incorporation or bylaws, any vacancy on the board of directors other than one
created by removal of a director may be filled by the board of directors. If the
number of directors then in office is less than a quorum, a vacancy may be
filled by the unanimous written consent of the directors then in office, by the
affirmative vote of a majority of the directors at a meeting held pursuant to
notice or waivers of notice or by a sole remaining director. A vacancy created
by removal of a director may be filled by the board only if so authorized by a
corporation's articles of incorporation or by a bylaw approved by the
corporation's shareholders. MBE's Bylaws permit vacancies created by removal of
a director to be filled only by a majority vote of the outstanding shares or
unanimous written consent in the absence of a meeting. Under the DGCL,
vacancies, including those created by removal, and newly created directorships
may be filled by a majority of the directors then in office or a sole remaining
director (even though less than a quorum), unless otherwise provided in the
certificate of incorporation or bylaws (and unless the certificate of
incorporation directs that a particular class is to elect such director, in
which case a majority of any other directors elected by such class, or a sole
remaining director, shall fill such vacancy). The USOP Charter provides for the
filling of vacancies by majority vote of the remaining directors, except that
stockholders may fill a vacancy created by the removal of a director in that
same meeting.
 
LOANS TO OFFICERS AND EMPLOYEES
 
    Under the CGCL, any loan or guaranty to or for a director or officer of the
corporation or its parent requires approval of a majority of a corporation's
shareholders entitled to act thereon, unless such loan or guaranty is authorized
under an employee benefit plan approved by a majority of the shareholders
entitled to act thereon (after disclosure to such shareholders that such plan
authorizes such loans or guaranties to or for officers and directors). In
addition, the CGCL provides that, notwithstanding the foregoing, if the
corporation has outstanding shares held of record by 100 or more shareholders on
the date such loan or guaranty is approved by the board of directors, and the
corporation has a bylaw approved by shareholders authorizing the board alone to
approve such loan or guaranty, such a loan or guaranty may be approved by the
board alone (excluding the vote of any interested director) if the board
determines that any such loan or guaranty may reasonably be expected to benefit
the corporation. The MBE Bylaws do not address, and hence do not authorize the
board to grant, such loans or guaranties. Under the DGCL, a corporation may make
loans to, guarantee the obligations of or otherwise assist its officers or other
employees and those of its subsidiaries (including directors who are also
officers or employees) when such action, in the judgment of the directors, may
reasonably be expected to benefit the corporation.
 
INDEMNIFICATION AND LIMITATION OF LIABILITY
 
    California and Delaware have similar laws respecting indemnification by a
corporation of its officers, directors, employees and other agents. The laws of
both states also permit, with certain exceptions, corporations to adopt a
provision in their articles or certificate of incorporation eliminating the
liability of a director to the corporation or its stockholders for monetary
damages for breach of the director's fiduciary duty of care. There are
nonetheless certain differences between the laws of the two states respecting
indemnification and limitation of liability.
 
                                       65
<PAGE>
    MBE's articles of incorporation eliminate the liability of directors to the
corporation to the fullest extent permissible under the CGCL. The CGCL does not
permit the elimination of monetary liability where such liability is based upon:
(a) intentional misconduct or knowing and culpable violation of law; (b) acts or
omissions that a director believes to be contrary to the best interests of the
corporation or its shareholders, or that involve the absence of good faith on
the part of the director; (c) receipt of an improper personal benefit; (d) acts
or omissions that show reckless disregard for the director's duty to the
corporation or its shareholders, where the director in the ordinary course of
performing a director's duties should be aware of a risk of serious injury to
the corporation or its shareholders; (e) acts or omissions that constitute an
unexcused pattern of inattention that amounts to an abdication of the director's
duty to the corporation and its shareholders; (f) interested transactions
between the corporation and a director in which a director has a material
financial interest; and (g) liability for improper distributions, loans or
guarantees.
 
    The USOP Charter also eliminates the liability of directors to the fullest
extent permissible under the DGCL. Under the DGCL, such provision may not
eliminate or limit director monetary liability for (a) breaches of the
director's duty of loyalty to the corporation or its stockholders; (b) acts or
omissions not in good faith or involving intentional misconduct or knowing
violations of law; (c) the payment of unlawful dividends or unlawful stock
repurchases or redemptions; or (d) transactions in which the director received
an improper personal benefit. Such limitation of liability provision also may
not limit a director's liability for violation of, or otherwise relieve USOP or
its directors from the necessity of complying with, federal or state securities
laws, or affect the availability of non-monetary remedies such as injunctive
relief or rescission.
 
    The CGCL permits indemnification of expenses incurred in derivative or
third-party actions, except that with respect to derivative actions (a) no
indemnification may be made without court approval when a person is adjudged
liable to the corporation in the performance of that person's duty to the
corporation and its shareholders, unless a court determines that such person is
fairly and reasonably entitled to indemnity for expenses, and then such
indemnification may be made only to the extent that such court shall determine,
and (b) no indemnification may be made in respect of amounts paid or expenses
incurred in settling or otherwise disposing of a threatened or pending action
without court approval or expenses incurred in defending a pending action which
is settled or otherwise disposed of without court approval.
 
    Indemnification is permitted by the CGCL only for actions taken in good
faith, reasonably believed to be lawful and believed to be in the best interests
of the corporation and its shareholders and not in violation of the requirements
described above, as determined by a majority vote of a quorum of the
disinterested directors, independent legal counsel (if a quorum of disinterested
directors is not obtainable), a majority vote of a quorum of the shareholders
(excluding shares owned by the indemnified party) or the court handling the
action. Indemnification is required when the individual has successfully
defended the action on the merits.
 
    The DGCL generally permits indemnification for expenses incurred in the
defense or settlement of a derivative or third-party action, provided there is a
determination that the person seeking indemnification acted in good faith and in
a manner reasonably believed to be both lawful and in, or (in contrast to the
CGCL) not opposed to, the best interests of the corporation. Such determination
may be made by the disinterested directors, by independent legal counsel or by a
majority vote of a quorum of the stockholders. Without court approval, however,
no indemnification may be made in respect of any derivative action in which such
person is adjudged liable to the corporation. The DGCL also requires
indemnification of expenses when the individual being indemnified has
successfully defended the action on the merits or otherwise.
 
    California corporations may include in their articles of incorporation a
provision which extends the scope of indemnification through agreements, bylaws
or other corporate action beyond that specifically authorized by statute except
to the extent expressly prohibited by statute. MBE's articles of incorporation
 
                                       66
<PAGE>
include such a provision. The USOP Charter authorizes indemnification to the
fullest extent permitted by law.
 
    Both the CGCL and DGCL provide that the indemnification permitted thereunder
shall not be deemed exclusive of any other rights under any bylaw, agreement,
vote of stockholders or disinterested directors or otherwise.
 
INSPECTION OF STOCKHOLDERS LIST
 
    Both the CGCL and the DGCL allow any stockholder to inspect the
stockholders' list for a purpose reasonably related to such person's interest as
a stockholder. The CGCL provides, in addition, for an absolute right to inspect
and copy the corporation's shareholder list by persons holding an aggregate of
five percent or more of a corporation's voting shares, or shareholders holding
an aggregate of one percent or more of such shares who have filed a Schedule 14A
with the Commission relating to the election of directors. The DGCL does not
provide for any such absolute right of inspection, and no such right is granted
under the USOP Charter or USOP Bylaws. Lack of access to stockholder records
could result in impairment of a stockholder's ability to coordinate opposition
to management proposals.
 
DIVIDENDS AND REPURCHASES OF SHARES
 
    The CGCL dispenses with the concepts of par value of shares as well as
statutory definitions of capital, surplus and the like. The concepts of par
value, capital and surplus are retained under the DGCL.
 
    Under the CGCL, a corporation may not make any distribution (including
dividends, whether in cash or other property, and repurchases of its shares)
unless either the corporation's retained earnings immediately prior to the
proposed distribution equal or exceed the amount of the proposed distribution
or, immediately after giving effect to such distribution, the corporation's
assets (exclusive of goodwill, capitalized research and development expenses and
deferred charges) would be at least equal to 1.25 times its liabilities (not
including deferred taxes, deferred income and other deferred credits), and the
corporation's current assets would be at least equal to its current liabilities
(or 1.25 times its current liabilities if the average pre-tax and pre-interest
expense earnings for the preceding two fiscal years were less than the average
interest expense for such years). Such tests are applied to California
corporations on a consolidated basis.
 
    The DGCL permits a corporation to declare and pay dividends out of surplus
or, if there is no surplus, out of net profits for the fiscal year in which the
dividend is declared or for the preceding fiscal year as long as the amount of
capital of the corporation following the declaration and payment of the dividend
is not less than the aggregate amount of the capital represented by the issued
and outstanding stock of all classes having a preference upon the distribution
of assets. In addition, the DGCL generally provides that a corporation may
redeem or repurchase its shares only if such redemption or repurchase would not
impair the capital of the corporation or if it repurchases shares having a
preference upon the liquidation of assets and it retires such shares upon
acquisition.
 
STOCKHOLDER VOTING
 
    Both the CGCL and the DGCL generally require that a majority of the
stockholders of both acquiring and target corporations approve mergers. The DGCL
does not require a stockholder vote of the surviving corporation in a merger
(unless the corporation provides otherwise in its certificate of incorporation)
if (a) the merger agreement does not amend the existing certificate of
incorporation, (b) each share of the surviving corporation before the merger is
an identical share after the merger, and (c) the number of shares to be issued
by the surviving corporation in the merger does not exceed 20% of the shares
outstanding immediately prior to the merger. The CGCL contains a similar
exception to its voting requirements for reorganizations where shareholders or
the corporation itself, or both, immediately prior
 
                                       67
<PAGE>
to the reorganization will own immediately after the reorganization equity
securities constituting more than five-sixths of the voting power of the
surviving or acquiring corporation or its parent entity.
 
    Both the CGCL and the DGCL also require that a sale of all or substantially
all of the assets of a corporation be approved by a majority of the voting
shares of the corporation transferring such assets. With certain exceptions, the
CGCL also requires that mergers, reorganizations, certain sales of assets and
similar transactions be approved by a majority vote of each class of shares
outstanding. In contrast, the DGCL generally does not require class voting,
except in certain transactions involving an amendment to the certificate of
incorporation which adversely affects a specific class of shares.
 
    The CGCL also requires that holders of nonredeemable shares of common stock
receive nonredeemable common stock in a merger of the corporation with the
holder of more than 50% but less than 90% of such common stock or its affiliate
unless all of the holders of such common stock consent to the transaction. This
provision of the CGCL may have the effect of making a "cash-out" merger by a
majority shareholder more difficult to accomplish. Although the DGCL does not
parallel the CGCL in this respect, under some circumstances, Section 203 of the
DGCL can provide similar protection against coercive two-tiered bids for a
corporation in which the stockholders are not treated equally. See
"--Stockholder Approval of Certain Business Combinations."
 
    The CGCL also provides that, except in certain circumstances, when a tender
offer or a proposal for a reorganization or for a sale of assets is made by an
interested party (generally a controlling or managing party of the target
corporation), an affirmative opinion in writing as to the fairness of the
consideration to be paid to the shareholders must be delivered to shareholders.
This fairness opinion requirement does not apply to a corporation which does not
have shares held of record by at least 100 persons, or to a transaction which
has been qualified under California state securities laws. Furthermore, if a
tender of shares or vote is sought pursuant to an interested party's proposal
and a later proposal is made by another party at least ten days prior to the
date of acceptance of the interested party's proposal, the shareholders must be
informed of the later proposal and be afforded a reasonable opportunity to
withdraw any vote, consent or proxy, or to withdraw any tendered shares. The
DGCL has no comparable provision, and the stockholders of USOP might, therefore,
be deprived of an opportunity to consider such other proposal.
 
INTERESTED DIRECTOR TRANSACTIONS
 
    Under both the CGCL and the DGCL, certain contracts or transactions in which
one or more of a corporation's directors has an interest are not void or
voidable because of such interest provided that certain conditions, such as
obtaining the required approval and fulfilling the requirements of good faith
and full disclosure, are met. Under the CGCL, however, if shareholder approval
of the interested transaction is sought, the interested director is not entitled
to vote his shares at a shareholder meeting with respect to the transaction and
if board approval is sought, the contract or transaction must be approved by a
majority vote of a quorum of the directors, without counting the vote of any
interested directors (except that interested directors may be counted for
purposes of establishing a quorum). Under the DGCL, if board approval is sought,
the contract or transaction must be approved by a majority of the disinterested
directors (even though less than a majority of a quorum). Therefore, certain
transactions that the Company Board might not be able to approve because of the
number of interested directors could be approved by a majority of the
disinterested directors of USOP, although less than a majority of a quorum.
 
STOCKHOLDER DERIVATIVE SUITS
 
    The CGCL provides that a shareholder bringing a derivative action on behalf
of a corporation need not have been a shareholder at the time of the transaction
in question, provided that certain tests are met. Under the DGCL, a stockholder
may only bring a derivative action on behalf of the corporation if the
stockholder was a stockholder of the corporation at the time of the transaction
in question or his or her stock thereafter devolved upon him or her by operation
of law. The CGCL also provides that the
 
                                       68
<PAGE>
corporation or the defendant in a derivative suit may make a motion to the court
for an order requiring the plaintiff shareholder to furnish a security bond.
Delaware does not have a similar bonding requirement.
 
DISSENTERS' OR APPRAISAL RIGHTS
 
    Under both the CGCL and the DGCL, a stockholder of a corporation
participating in certain major corporate transactions may, under varying
circumstances, be entitled to dissenters' or appraisal rights pursuant to which
such stockholder may receive cash in the amount of the fair market value of his
or her shares in lieu of the consideration he or she would otherwise receive in
the transaction. Under the DGCL, such appraisal rights are not available (a)
with respect to the sale, lease or exchange of all or substantially all of the
assets of a corporation (unless specifically provided for in the certificate of
incorporation), (b) with respect to a merger or consolidation by a corporation
the shares of which are either listed on a national securities exchange or are
held of record by more than 2,000 holders if such stockholders receive only
shares of the surviving corporation or shares of any other corporation which are
either listed on a national securities exchange or held of record by more than
2,000 holders, plus cash in lieu of fractional shares, or (c) to stockholders of
a corporation surviving a merger if no vote of the stockholders of the surviving
corporation is required to approve the merger.
 
    The limitations on the availability of appraisal rights under the CGCL are
different from those under the DGCL. Shareholders of a California corporation
(such as MBE) whose shares are listed on a national securities exchange or on a
list of over-the-counter margin stocks issued by the Board of Governors of the
Federal Reserve System generally do not have such appraisal rights unless the
holders of at least 5% of the class of outstanding shares claim the right or the
corporation or any law restricts the transfer of such shares. Appraisal rights
are unavailable, however, if the shareholders of a corporation or the
corporation itself, or both, immediately prior to the reorganization will own
immediately after the reorganization equity securities constituting more than
five-sixths of the voting power of the surviving or acquiring corporation or its
parent entity. In general, the CGCL affords appraisal rights in sale of asset
reorganizations.

<PAGE>
                             SHAREHOLDER PROPOSALS
 
    Any MBE shareholder who intended to submit a shareholder proposal to be
considered at the next annual meeting of MBE shareholders must have submitted
such proposal by March 14, 1997. If the Merger is completed, no Annual Meeting
of MBE Shareholders will be held.

    Certain legal matters with respect to the validity of the securities offered

                          AGREEMENT AND PLAN OF MERGER
 
    AGREEMENT AND PLAN OF MERGER, dated as of May 22, 1997, among U. S. OFFICE
PRODUCTS COMPANY, a Delaware corporation ("PARENT"), SANTA FE ACQUISITION CORP.,
a California corporation and a direct, wholly-owned subsidiary of Parent
("SUB"), and Mail Boxes Etc., a California corporation (the "COMPANY").
 
                                   BACKGROUND
 
    A. The respective Boards of Directors of Parent, Sub and the Company have
approved the merger of Sub with and into the Company (the "MERGER"), upon the
terms and subject to the conditions set forth in this Agreement and in
accordance with the General Corporation Law of the State of California (the
"CGCL"), whereby each issued and outstanding share of common stock of the
Company, no par value per share (the "COMPANY COMMON STOCK"), other than shares
to be cancelled in accordance with Section 2.1(b), will be converted into the
right to receive a certain number of shares of common stock, $.001 par value per
share, of Parent ("PARENT COMMON STOCK"), such number to be determined as
provided herein.
 
    B. The Merger requires the approval of the holders of a majority of the
outstanding shares of the Company Common Stock (the "COMPANY STOCKHOLDER
APPROVAL").
 
    C. Parent, Sub and the Company desire to make certain representations,
warranties, covenants and agreements in connection with the Merger and also to
prescribe various conditions to the Merger.
 
    D. For federal income tax purposes, it is intended that the Merger will
qualify as a reorganization within the meaning of Sections 368(a)(1)(A) and
(a)(2)(E) of the Internal Revenue Code of 1986, as amended (the "CODE").
 
    E. For accounting purposes, it is intended that the Merger will be accounted
for as a "POOLING-OF-INTERESTS."
 
    F. Concurrently with the execution of this Agreement and as an inducement to
Parent to enter into this Agreement, Michael Dooling, Anthony DeSio, and United
Parcel Service, stockholders of the Company (the "SIGNIFICANT STOCKHOLDERS"),
have entered into a voting agreement with Parent (the "SIGNIFICANT STOCKHOLDER
AGREEMENT") in the form of Exhibit B hereto pursuant to which the Significant
Stockholders have, among other things, agreed to vote their shares of the
Company Common Stock in favor of the Merger. In addition, concurrent with the
execution of this Agreement, the Company has obtained from each other affiliate
of the Company a written agreement in substantially the form of Exhibit 5.9
hereto and a copy of such agreement has been delivered to Parent.
 
                                   AGREEMENT
 
    In consideration of the representations, warranties, covenants and
agreements contained in this Agreement, the parties agree as follows:
 
                                   ARTICLE I
                                   THE MERGER
 
    SECTION 1.1  THE MERGER.  Upon the terms and subject to the conditions set
forth in this Agreement, and in accordance with the CGCL, Sub shall be merged
with and into the Company at the Effective Time (as defined in Section 1.3).
Following the Merger, the separate corporate existence of Sub shall cease and
the Company shall continue as the surviving corporation (the "SURVIVING
CORPORATION") and shall succeed to and assume all the rights and obligations of
the Company and of Sub in accordance with the CGCL.
 
                                       4
<PAGE>
    SECTION 1.2  CLOSING.  The closing of the Merger will take place at 10:00
a.m. on a date to be specified by the parties, which shall be no later than the
second business day after satisfaction or waiver of the conditions set forth in
Article VI (the "CLOSING DATE"), at the offices of O'Melveny & Myers LLP, Suite
1700, 610 Newport Center Drive, Newport Beach, California 92660, unless another
time, date or place is agreed to in writing by the parties hereto.

an officers' certificate for each of Sub and the Company, and (iii) a
certificate of satisfaction of the California Franchise Tax Board for each of
Sub and the Company, all as required by Section 1103 of the CGCL (such
documents, the "MERGER DOCUMENTS"), and shall make all other filings or
recordings required under the CGCL. The Merger shall become effective at such
time as the Merger Documents are duly filed with the California Secretary of
State, or at such other time as Sub and the Company shall agree should be
specified in the documents to be filed with the Secretary of State (the date and
time of such filing, or such later date or time as may be set forth therein,
being the "EFFECTIVE TIME").
 
    SECTION 1.4  EFFECTS OF THE MERGER.  The Merger shall have the effects set

applicable provisions of the CGCL.
 
    SECTION 1.5  ARTICLES OF INCORPORATION AND BY-LAWS.
 
    (a) From and after the Effective Time, the articles of incorporation of the
Company shall be the articles of incorporation of the Surviving Corporation
until thereafter changed or amended as provided therein or by applicable law.
 
    (b) From and after the Effective Time, the bylaws of Sub shall be the Bylaws
of the Surviving Corporation until thereafter changed or amended as provided
therein or by applicable law.
 
    SECTION 1.6  DIRECTORS AND OFFICERS.  The initial directors of the Surviving
Corporation shall be the directors of Sub immediately prior to the Effective
Time, each to serve until their successors have been duly elected or appointed
and qualified or until their earlier death, resignation or removal in accordance
with the Surviving Corporation's articles of incorporation and bylaws. The
initial officers of the Surviving Corporation shall be the officers of the
Company immediately prior to the Effective Time, with the addition of Mark D.
Director as Assistant Secretary of the Surviving Corporation, each to serve
until their successors have been duly elected or appointed and qualified or
until their earlier death, resignation or removal in accordance with the
Surviving Corporation's articles of incorporation and bylaws.
 
    SECTION 1.7  ADDITIONAL ACTIONS.  If, at any time after the Effective Time,
the Surviving Corporation shall consider or be advised that any deeds, bills of
sale, assignments, assurances or any other actions or things are necessary or
desirable to vest, perfect or confirm of record or otherwise in the Surviving
Corporation its right, title or interest in, to or under any of the rights,
properties or assets of Sub or the Company or otherwise to carry out this
Agreement, the officers and directors of the Surviving Corporation shall be
authorized to execute and deliver, in the name and on behalf of Sub or the
Company, all such deeds, bills of sale, assignments and assurances and to take
and do, in the name and on behalf of Sub or the Company, all such other actions
and things as may be necessary or desirable to vest, perfect or confirm any and
all right, title and interest in, to and under such rights, properties or assets

                                   ARTICLE II
                EFFECT OF THE MERGER ON THE CAPITAL STOCK OF THE
               CONSTITUENT CORPORATIONS; EXCHANGE OF CERTIFICATES
 
    SECTION 2.1  EFFECT ON CAPITAL STOCK.  At the Effective Time, by virtue of
the Merger and without any action on the part of Parent, Sub, the Company, or
the holders of any shares of the Company Common Stock or any shares of capital
stock of Sub:
 
    (a)  CAPITAL STOCK OF SUB.  Each share of the capital stock of Sub issued
and outstanding immediately prior to the Effective Time shall be converted into
and exchanged for one fully paid and nonassessable share of common stock of the
Surviving Corporation.
 
    (b)  CANCELLATION OF PARENT OWNED STOCK.  Each share of the Company Common
Stock that is owned by Parent, Sub or any other subsidiary of Parent immediately
prior to the Effective Time shall automatically be cancelled and retired without
any conversion thereof and no consideration shall be delivered with respect
thereto.
 
    (c)  CONVERSION OF COMMON STOCK.  Each share of Company Common Stock issued
and outstanding as of the Effective Time, other than shares to be cancelled in
accordance with Section 2.1(b) or that are held by stockholders ("DISSENTING
STOCKHOLDERS") duly exercising dissenters' rights pursuant to Chapter 13 of the
CGCL and Section 2.3 hereof, shall be converted, subject to Section 2.2(d), into
the right to receive one share of Parent Common Stock (the "EXCHANGE RATIO"),
subject to adjustment as provided for in this Section 2.1(c). The Exchange Ratio
shall not be adjusted if the Share Value (as defined below) is equal to or
greater than $23.00, but no greater than $29.00. If the Share Value is greater
than $29.00, then the Exchange Ratio shall automatically be adjusted to equal
the quotient of (i) $29.00 divided by (ii) the Share Value. If the Share Value
is less than $23.00, then, if the Company has notified Parent of its election to
terminate this Agreement pursuant to Section 7.1(i) hereof, Parent shall have
the option in its sole and absolute discretion, but not the obligation, to
adjust the Exchange Ratio to be equal to the quotient of (iii) $23.00, divided
by (iv) the Share Value, and the Company shall be obligated to accept such
adjustment. If the Share Value is less than $23.00, and if the Company does not
elect to terminate this Agreement pursuant to Section 7.1(i), the Exchange Ratio
shall be unchanged.
 
    For purposes hereof, the "SHARE VALUE" shall be an amount equal to the
average closing price for the Parent Common Stock as reported on the Nasdaq
National Market System for the twenty (20) consecutive trading days prior to the
date two (2) business days prior to the Company Stockholders' Meeting (as
defined in Section 5.1(d), so long as the Closing Date occurs within five
business days of the Company Stockholders' Meeting or, if the Closing Date is
more than five business days after the Company Stockholders' Meeting, the
Closing Date.
 
    As of the Effective Time, all such shares of the Company Common Stock shall
no longer be outstanding and shall automatically be cancelled and retired and
shall cease to exist, and each certificate previously representing any such
shares shall thereafter represent only the right to receive a certificate
representing the shares of Parent Common Stock into which such the Company
Common Stock was converted in the Merger. The holders of such certificates
previously evidencing such shares of the Company Common Stock outstanding
immediately prior to the Effective Time shall cease to have any rights with
respect to such shares of the Company Common Stock as of the Effective Time
except as otherwise provided herein or by law. Such certificates previously
representing shares of the Company Common Stock shall be exchanged for
certificates representing whole shares of Parent Common Stock issued in
consideration therefor upon the surrender of such certificates in accordance
with the provisions of Section 2.2, without interest. No fractional shares of
Parent Common Stock shall be issued, and, in lieu thereof, a cash payment shall
be made pursuant to Section 2.2(d).
 
                                       6
<PAGE>
    SECTION 2.2  EXCHANGE OF CERTIFICATES.
 
    (a)  EXCHANGE PROCEDURE.  As soon as reasonably practicable after the
Effective Time, Parent shall cause to be mailed to each holder of record of a
certificate or certificates which immediately prior to the Effective Time
represented outstanding shares of the Company Common Stock (the "CERTIFICATES"),
(i) a letter of transmittal (which shall be in customary form and shall specify
that delivery shall be effected, and risk of loss and title to the Certificates
shall pass, only upon proper delivery of the Certificates to Parent's transfer
agent (the "TRANSFER AGENT")), and (ii) instructions for use in effecting the
surrender of the Certificates in exchange for certificates representing shares
of Parent Common Stock. Upon surrender of a Certificate for cancellation to the
Transfer Agent, together with such letter of transmittal, duly executed, and
such other documents as may reasonably be required by the Transfer Agent, the
holder of such Certificate shall be entitled to receive in exchange therefor a
certificate evidencing that number of whole shares of Parent Common Stock which
such holder has the right to receive in respect of the shares of the Company
Common Stock formerly evidenced by such Certificate (after taking into account
all shares of the Company Common Stock then held of record by such holder), cash
in lieu of fractional shares of Parent Common Stock to which such holder is
entitled pursuant to Section 2.2(d) and any dividends or other distributions to
which such holder is entitled pursuant to Section 2.2(b), and the Certificate so
surrendered shall forthwith be cancelled. In the event of a transfer of
ownership of the Company Common Stock which is not registered in the transfer
records of the Company, a certificate representing the proper number of shares
of Parent Common Stock may be issued to a person other than the person in whose
name the Certificate so surrendered is registered, if such Certificate,
accompanied by all documents required to evidence and effect such transfer,
shall be properly endorsed with signature guarantee or otherwise be in proper
form for transfer and the person requesting such payment shall pay any transfer
or other taxes required by reason of the issuance of shares of Parent Common
Stock to a person other than the registered holder of such Certificate or
establish to the satisfaction of Parent that such tax has been paid or is not
applicable. Until surrendered as contemplated by this Section 2.2, each
Certificate shall be deemed at any time after the Effective Time to represent
only the right to receive upon such surrender the certificate evidencing whole
shares of Parent Common Stock, cash in lieu of any fractional shares of Parent
Common Stock to which such holder is entitled pursuant to Section 2.2(d) and any
dividends or other distributions to which such holder is entitled pursuant to
Section 2.2(b). No interest will be paid or will accrue on any cash payable
pursuant to Section 2.2(b) or 2.2(d).
 
    (b)  DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED SHARES.  No dividends or
other distributions declared or made after the Effective Time with respect to
Parent Common Stock with a record date after the Effective Time shall be paid to
the holder of any unsurrendered Certificate with respect to the shares of Parent
Common Stock represented thereby, and no cash payment in lieu of fractional
shares shall be paid to any such holder pursuant to Section 2.2(d), in each case
until the surrender of such Certificate in accordance with this Article II.
Subject to the effect of applicable escheat laws, following surrender of such
Certificate, there shall be paid to the holder of the certificate representing
whole shares of Parent Common Stock issued in exchange therefor, without
interest, (i) at the time of such surrender, the amount of any such cash payable
in lieu of a fractional share of Parent Common Stock to which such holder is
entitled pursuant to Section 2.2(d) and the amount of dividends or other
distributions with a record date after the Effective Time theretofore paid with
respect to such whole shares of Parent Common Stock, and (ii) at the appropriate
payment date, the amount of dividends or other distributions with a record date
after the Effective Time but prior to such surrender and with a payment date
subsequent to such surrender payable with respect to such whole shares of Parent
Common Stock.
 
    (c)  NO FURTHER OWNERSHIP RIGHTS IN THE COMPANY COMMON STOCK.  All shares of
Parent Common Stock issued upon the surrender for exchange of Certificates in
accordance with the terms of this Article II (including any cash paid pursuant
to Section 2.2(b) or 2.2(d)) shall be deemed to have been issued (and paid) in
full satisfaction of all rights pertaining to the shares of the Company Common
Stock theretofore represented by such Certificates, subject, however, to the
Surviving Corporation's obligation to pay any dividends or make any other
distributions with a record date prior to the Effective Time which may have
 
                                       7
<PAGE>
been declared or made by the Company on such shares of the Company Common Stock
in accordance with the terms of this Agreement or prior to the date of this
Agreement and which remain unpaid at the Effective Time and have not been paid
prior to surrender. At the Effective Time, the stock transfer books of the
Company shall be closed, and there shall be no further registrations of
transfers of shares of the Company Common Stock thereafter on the records of the
Company. If, after the Effective Time, Certificates are presented to the
Surviving Corporation, Parent or the Transfer Agent for any reason, they shall
be cancelled and exchanged as provided in this Article II.
 
    (d)  NO FRACTIONAL SHARES.
 
        (i) No Certificates or scrip representing fractional shares of Parent
    Common Stock shall be issued upon the surrender for exchange of
    Certificates, and such fractional share interests will not entitle the owner
    thereof to vote or to any rights of a stockholder of Parent.
 
        (ii) Each holder of shares of Company Common Stock issued and
    outstanding at the Effective Time who would otherwise be entitled to receive
    a fractional share of Parent Common Stock upon surrender of stock
    certificates for exchange pursuant to this Article II (after taking into
    account all shares of Company Common Stock then held by such holder) shall
    receive, in lieu thereof, cash in an amount equal to the value of such
    fractional shares, which shall be equal to the fraction of a share of Parent
    Common Stock that would otherwise be issued multiplied by the Share Value.
 
       (iii) As soon as practicable after the determination of the amount of
    cash, if any, to be paid to holders of Certificates with respect to any
    fractional share interests, Parent shall promptly pay such amounts to such
    holders of Certificates subject to and in accordance with the terms of
    Section 2.2(b).
 
    (e)  NO LIABILITY.  None of Parent, Sub, the Company or the Transfer Agent
shall be liable to any holder of shares of the Company Common Stock for any
shares of Parent Common Stock (or dividends or distributions with respect
thereto) or cash otherwise deliverable or payable to any holder of shares of the
Company Common Stock to a public official pursuant to any applicable abandoned
property, escheat or similar law.
 
    SECTION 2.3  DISSENTERS' RIGHTS.  If any Dissenting Stockholder shall be
entitled to require the Company to purchase such stockholder's shares for their
fair market value, as provided in Chapter 13 of the CGCL, the Company shall give
Parent notice thereof and Parent shall have the right to participate in all
negotiations and proceedings with respect to any such demands. Neither the
Company nor the Surviving Corporation shall, except with the prior written
consent of Parent, voluntarily make any payment with respect to, or settle or
offer to settle, any such demand for payment. If any Dissenting Stockholder
shall fail to perfect or shall have effectively withdrawn or lost the right to
dissent, the shares held by such stockholder shall thereupon be entitled to be
surrendered in exchange for shares of Parent Common Stock as provided by
Sections 2.1 and 2.2 hereof.
 
                                  ARTICLE III
 
                         REPRESENTATIONS AND WARRANTIES
 
    SECTION 3.1 REPRESENTATIONS AND WARRANTIES OF THE COMPANY. Except as set
forth on the disclosure schedule (provided that an item on such disclosure
schedule shall be deemed to qualify only the particular subsection or
subsections of this Section 3.1 specified for such item) delivered by the
Company to Parent prior to the execution of this Agreement (the "COMPANY
DISCLOSURE SCHEDULE"), the Company represents and warrants to Parent and Sub as
follows:
 
    (a) ORGANIZATION, STANDING AND CORPORATE POWER. The Company and each of its
subsidiaries is a corporation duly organized, validly existing and in good
standing under the laws of the jurisdiction in which it is organized and has the
requisite corporate power and authority to carry on its business as now being
conducted. The Company and each of its subsidiaries is duly qualified or
licensed to do business and is in good standing in each jurisdiction in which
the nature of its business or the ownership or leasing of its properties makes
such qualification or licensing necessary, other than in such jurisdictions
where the failure to be so qualified or licensed would not, individually or in
the aggregate, have a "material adverse effect" (as defined in Section 8.3) on
the Company.
 
                                       8
<PAGE>
    (b) SUBSIDIARIES. The Company Disclosure Schedule lists each subsidiary of
the Company and its jurisdiction of incorporation or organization. All of the
outstanding shares of capital stock of each such subsidiary have been validly
issued and are fully paid and nonassessable and are owned by the Company, by
another subsidiary of the Company or by the Company and another such subsidiary,
free and clear of all pledges, claims, liens, charges, encumbrances and security
interests of any kind or nature whatsoever (collectively, "LIENS"). Except for
the capital stock of its subsidiaries, and as disclosed in the Company
Disclosure Schedule, the Company does not own, directly or indirectly, any
capital stock or other ownership interest in any corporation, partnership, joint
venture or other entity.
 
    (c) CAPITAL STRUCTURE. The authorized capital stock of the Company consists
of 40,000,000 shares of the Company Common Stock, no par value per share, and
10,000,000 shares of preferred stock, no par value per share (the "COMPANY
PREFERRED STOCK"). At the close of business on April 30, 1997, (i) 11,300,273
shares of the Company Common Stock and no shares of the Company Preferred Stock
were issued and outstanding, (ii) 1,281,882 shares of the Company Common Stock
were reserved for issuance upon exercise of outstanding Stock Options (as
defined in Section 5.4), and (iii) an aggregate of 2,779,127 shares of the
Company Common Stock were reserved for issuance under the Company's Stock
Option/Purchase Plans (as defined in Section 5.4). Except as set forth above, at
the close of business on April 30, 1997 and since April 30, 1997, no shares of
capital stock or other voting securities of the Company were issued, reserved
for issuance or outstanding and since April 30, 1997 no shares of capital stock
or other voting securities of the Company have been issued by the Company except
upon exercise of Stock Options outstanding on April 30, 1997. There are no
outstanding stock appreciation rights of the Company and no outstanding limited
stock appreciation rights or other rights to redeem for cash options or warrants
of the Company. All outstanding shares of capital stock of the Company are, and
all shares which may be issued upon the exercise of Stock Options will be, when
issued, duly authorized, validly issued, fully paid and nonassessable and not
subject to preemptive rights. All of the issued and outstanding shares of the
capital stock of the Company were offered, issued, sold and delivered by the
Company in compliance with all applicable state and federal laws concerning the
issuance of securities. There are no bonds, debentures, notes or other
indebtedness of the Company having the right to vote (or convertible into, or
exchangeable for, securities having the right to vote) on any matters on which
stockholders of the Company may vote. Except as set forth above, as of the date
of this Agreement, there are no outstanding securities, options, warrants,
calls, rights, commitments, agreements, arrangements or undertakings of any kind
to which the Company or any of its subsidiaries is a party or by which any of
them is bound obligating the Company or any of its subsidiaries to issue,
deliver or sell, or cause to be issued, delivered or sold, additional shares of
capital stock or other voting securities of the Company or of any of its
subsidiaries or obligating the Company or any of its subsidiaries to issue,
grant, extend or enter into any such security, option, warrant, call, right,
commitment, agreement, arrangement or undertaking. There are no outstanding
contractual obligations of the Company or any of its subsidiaries to repurchase,
redeem or otherwise acquire any shares of capital stock (or options to acquire
any such shares) of the Company or any of its subsidiaries. There are no
agreements, arrangements or commitments of any character (contingent or
otherwise) pursuant to which the Company or any of its subsidiaries is required
to file a registration statement under the Securities Act of 1933, as amended
(the "SECURITIES ACT"), or which otherwise relate to the registration of any
securities of the Company.
 
    (d) AUTHORITY; NONCONTRAVENTION.
 
        (i) The Company has the requisite corporate power and authority to enter
    into this Agreement and, subject to the Company Stockholder Approval, to
    consummate the transactions contemplated by this Agreement. The execution
    and delivery of this Agreement by the Company and the consummation by the
    Company of the transactions contemplated by this Agreement have been duly
    authorized by all necessary corporate action on the part of the Company,
    subject to the Company Stockholder Approval of this Agreement. This
    Agreement has been duly executed and delivered by the Company and

    limited by applicable bankruptcy, reorganization, moratorium or other such
    law. The execution and delivery of this Agreement does not, and the
    consummation of the transactions contemplated by this Agreement and
    compliance with the provisions of this Agreement will not, conflict with, or
    result in any violation of or default (with or without notice or lapse of
    time, or both) under, or give rise to a right of termination, cancellation
    or acceleration of any obligation or to loss of any benefit under, or result
    in the creation of any Lien upon any of the properties or assets of the
    Company or any of its subsidiaries under, (i) the articles of incorporation
    or bylaws of the Company or the comparable charter or organizational
    documents of any of its subsidiaries, (ii) any loan or credit agreement,
    note, bond, mortgage, indenture, lease or other agreement, instrument,
    permit, concession, franchise or license applicable to or, in the case of
    franchises or licenses, granted by, the Company or any of its subsidiaries
    or otherwise applicable to their respective properties or assets or (iii)
    subject to the governmental filings and other matters referred to in the
    following sentence, any judgment, order, decree, injunction, statute, law,
    ordinance, rule or regulation applicable to the Company or any of its
    subsidiaries or their respective properties or assets, other than, in the
    case of clause (ii), any such conflicts, violations, defaults, rights or
    Liens that would not, individually or in the aggregate, have a material
    adverse effect on the Company.
 
        (ii) No consent, approval, order or authorization of, or registration,
    declaration or filing with, any federal, state or local government or any
    court, administrative or regulatory agency or commission or other
    governmental authority or agency, domestic or foreign (a "GOVERNMENTAL
    ENTITY"), is required by the Company or any of its subsidiaries in
    connection with the execution and delivery of this Agreement by the Company
    or the consummation by the Company of the transactions contemplated by this
    Agreement, except for (A) the filing with the Federal Trade Commission and
    the Antitrust Division of the Department of Justice (the "SPECIFIED
    AGENCIES") of a premerger notification and report form by the Company under
    the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (the "HSR ACT"),
    (B) the filing with the Securities and Exchange Commission (the "SEC") of
    (1) the Proxy Statement (as defined in Section 5.1) and (2) such reports
    under Section 13(a) of the Securities Exchange Act of 1934, as amended (the
    "EXCHANGE ACT"), as may be required in connection with this Agreement and
    the transactions contemplated by this Agreement and (C) the filing of the
    Merger Documents with the California Secretary of State and appropriate
    documents with the relevant authorities of other states in which the Company
    is qualified to do business.
 
       (iii) The Company hereby represents that its Board of Directors, at a
    meeting duly called and held, has unanimously (A) determined that this
    Agreement and the transactions contemplated hereby, including the Merger,
    are fair to and in the best interest of the Company's stockholders, (B)
    approved this Agreement and the transactions contemplated hereby, including
    the Merger, which approval satisfies in full the requirements of the CGCL
    with respect to the transactions contemplated hereby, and (C) resolved to
    recommend approval and adoption of this Agreement and the Merger by its
    stockholders.
 
    (e) SEC DOCUMENTS; FINANCIAL STATEMENTS.
 
        (i) The Company has filed with the SEC all reports and forms and other
    documents required to be filed by it pursuant to relevant United States
    securities statutes, regulations, policies and rules (the "SEC DOCUMENTS"),
    all of which have complied in all material respects with all applicable
    requirements of such statutes, regulations, policies and rules. As of their
    respective dates, none of the SEC Documents, except as revised or superseded
    by a later filed SEC Document, without regard to any amendments or filings
    after the date hereof, contained any untrue statement of a material fact or
    omitted to state a material fact required to be stated therein or necessary
    in order to make the statements therein, in light of the circumstances under
    which they were made, not misleading. In addition, nothing has come to the
    attention of the Company since the date any SEC Document was filed that
    would have made, as of the filing date, any statement in any SEC Document
    untrue in a
 
                                       10
<PAGE>
    material respect, or that, if omitted to be stated as of the filing date,
    would have made the statements in such SEC Document, in light of the
    circumstances under which they were made, misleading. Except to the extent
    that information contained in any SEC Document has been revised or
    superseded by a later-filed SEC Document filed and publicly available prior
    to the date of this Agreement, none of the SEC Documents contains any untrue
    statement of a material fact or omits to state any material fact required to
    be stated therein or necessary in order to make the statements therein, in
    light of the circumstances under which they were made, not misleading. The
    financial statements of the Company included in the SEC Documents have been
    prepared in accordance with generally accepted accounting principles
    (except, in the case of unaudited statements, as permitted by Form 10-Q of
    the SEC) applied on a consistent basis during the periods involved (except
    as may be indicated in the notes thereto) and fairly present the
    consolidated financial position of the Company and its consolidated
    subsidiaries as of the dates thereof and the consolidated results of their
    operations and cash flows for the periods then ended (subject, in the case
    of unaudited statements, to the omission of footnote information and normal
    year-end audit adjustments consisting of normal, recurring accruals that are
    not material).
 
        (ii) The books, records and accounts of the Company and its subsidiaries
    (A) have been maintained in accordance with good business practices on a
    basis consistent with prior years, (B) are stated in reasonable detail and
    accurately and fairly reflect in all material respects the transactions and
    dispositions of the assets of the Company and its subsidiaries and (C)
    accurately and fairly reflect in all material respects the basis for the
    Company's financial statements. The Company has devised and maintains a
    system of internal accounting controls sufficient to provide reasonable
    assurances that (D) transactions are executed in accordance with
    management's general or specific authorization; and (E) transactions are
    recorded as necessary (1) to permit preparation of financial statements in
    conformity with generally accepted accounting principles or any other
    criteria applicable to such statements and (2) to maintain accountability
    for assets.
 
       (iii) Except as set forth in the SEC Documents filed prior to the date of
    this Agreement, and except for liabilities and obligations incurred in the
    ordinary course of business consistent with past practice since April 30,
    1996, neither the Company nor any of its subsidiaries has any material
    liabilities or obligations of any nature (whether accrued, absolute,
    contingent or otherwise).
 
    (f) INFORMATION SUPPLIED. None of the information supplied or to be supplied
by the Company specifically for inclusion or incorporation by reference in (i)
the Form S-4 (as defined in Section 5.1) will, at the time the Form S-4 is filed
with the SEC, at any time it is amended or supplemented or at the time it
becomes effective under the Securities Act, contain any untrue statement of a
material fact or omit to state any material fact required to be stated therein
or necessary to make the statements therein, in light of the circumstances under
which they are made, not misleading or (ii) the Proxy Statement will, at the
date it is first mailed to the Company's stockholders or at the time of the
Company Stockholders' Meeting, contain any untrue statement of a material fact
or omit to state any material fact required to be stated therein or necessary in
order to make the statements therein, in light of the circumstances under which
they are made, not misleading. The Proxy Statement will comply as to form in all
material respects with the requirements of the Exchange Act and the rules and
regulations thereunder, except that no representation or warranty is made by the
Company with respect to statements made or incorporated by reference therein
based on information supplied by Parent or Sub specifically for inclusion or
incorporation by reference in the Proxy Statement.
 
    (g) NO DEFAULTS. Neither the Company nor any of its subsidiaries is, or has
received notice that it would be with the passage of time, in default or
violation of any term, condition or provision of (i) the articles of
incorporation or bylaws of the Company or the comparable charter or
organizational documents of any of its subsidiaries, (ii) any loan or credit
agreement, note, bond, mortgage, indenture, lease or other agreement,
instrument, permit, concession, franchise or license applicable to or, in the
case of franchises or licenses, granted by, the Company or any of its
subsidiaries or otherwise applicable to their respective
 
                                       11
<PAGE>
properties or assets or (iii) any judgment, order, decree, injunction, statute,
law, ordinance, rule or regulation applicable to the Company or any of its
subsidiaries or their respective properties or assets, other than, in the case
of clause (ii) and, with respect to statutes, laws, ordinances, rules or
regulations, clause (iii), any such defaults or violations that would not,
individually or in the aggregate, have a material adverse effect on the Company.
 
    (h) ABSENCE OF CERTAIN CHANGES OR EVENTS. Except as disclosed in the SEC
Documents filed prior to the date of this Agreement, since April 30, 1996 the
Company and its subsidiaries have conducted their businesses only in the
ordinary course consistent with prior practice, and there has not been (i) any
material adverse change in the Company's business, operations, affairs,
prospects, properties, assets, profits or condition (financial or otherwise),
(ii) any declaration, setting aside or payment of any dividend or other
distribution (whether in cash, stock or property) with respect to any of the
Company's capital stock, (iii) any split, combination or reclassification of any
of its capital stock or any issuance or the authorization of any issuance of any
other securities in respect of, in lieu of or in substitution for shares of its
capital stock, (iv) any amendment of any material term of any outstanding
security of the Company or any subsidiary, (v) any sale, encumbrance, assignment

acquisition of any corporation, partnership or other business organization or

and in amounts and on terms consistent with past practices, or any change in the
material terms of any such indebtedness or guarantee of the Company or any
subsidiary (including indebtedness of a third party subject to any such
guarantee), (viii) any granting by the Company or any of its subsidiaries to any
officer or employee of the Company or any of its subsidiaries of any increase in
compensation, except in the ordinary course of business consistent with prior
practice or as was required under employment agreements in effect as of the date
of the most recent audited financial statements included in the SEC Documents
filed prior to the date of this Agreement (a list of all such employment
agreements being set forth in Schedule 3.1(h) to Section 3.1(h) of the Company
Disclosure Schedule), (ix) any granting by the Company or any of its
subsidiaries to any such officer or employee of any increase in severance or

required by a change in generally accepted accounting principles.
 
    (i) LITIGATION. Except as disclosed in the SEC Documents filed prior to the
date of this Agreement, there is no claim, suit, action, investigation, audit or

there any judgment, order, decree or injunction applicable to the Company or any
of its subsidiaries that, individually or in the aggregate, could reasonably be
expected to have any such effect.
 
    (j) ABSENCE OF CHANGES IN BENEFIT PLANS.
 
        (i) Except as disclosed in the SEC Documents filed prior to the date of

       result of the transactions contemplated by this Agreement;
 
           (G) with respect to each Company Plan, there has occurred no

    trademarks, trade dress franchises, domain names and similar rights now used
    or employed in the business of the Company and its subsidiaries (the
    "INTELLECTUAL PROPERTY") and such rights will not cease to be valid rights

    Intellectual Property by the Company and its subsidiaries does not and will
    not conflict with, infringe upon or otherwise violate the valid rights of
    any third party in or to such Intellectual Property, and no action has been
    instituted against or notices received by the Company or any subsidiary that

    state all material information (including but not limited to the discussion
    of litigation matters) set forth in them; (C) do not omit any required
    material information; (D) accurately state the Company's position that it
    does not provide to prospective area or individual franchisees "earnings
    claims" information (as that term is defined in the FTC's franchise
    disclosure regulations and the North American Securities Administrators
    Association's current Uniform Franchise Offering Circular Guidelines); (E)
    have been timely revised to reflect any material changes or developments in
    the Company's franchise system, agreements, operations, financial condition,
    litigation matters, or other matters requiring disclosure under any
    applicable foreign, federal, state, and/or local law; and (F) include all
    material documents (including but not limited to audited financial
    statements for the Company) required by any applicable foreign, federal,
    state, and/or local law to be provided to prospective area franchisees,
    individual franchisees and/or, if applicable, any licensees.
 
        (ii) FRANCHISE AND LICENSE AGREEMENTS. The Company's past and present
    agreements with its area franchisees, individual franchisees, and licenses:
    (A) materially comply with applicable foreign, federal, state, and/or local
    laws and regulations; (B) do not include provisions that would prevent or
    otherwise impair the Company's ability to undergo a change in ownership or
    control or require the
 
                                       20

    obligation to comply with all applicable federal, state, and local laws and
    regulations; and (F) impose on area franchisees, individual franchisees, and

    names the Company as an additional insured, requires the insurer to notify
    the Company before it terminates any such insurance policy for nonpayment,
    and permits the Company to make such payments to maintain such insurance
    coverage on behalf of any non-paying area franchisee, individual franchisee,
    or licensee.
 
        (iii) REGISTRATION AND DISCLOSURE COMPLIANCE. All of the area
    franchises, individual franchises, and licenses of the Company have been
    sold in material compliance with applicable foreign, federal, state, and/or
    local franchise disclosure and registration requirements. As a result,
 
           (A) each prospective area franchisee, individual franchisee, and, if
       applicable, licensee was provided with any required FOC at the earlier of
       (1) the first personal face-to-face meeting between the Company and the
       then prospect for the purposes of discussing the acquisition of an area
       franchise, individual franchise, or, if applicable, license, (2) at least
       ten business days before the execution of any agreement with the Company

       franchisee, individual franchisee, or, if applicable, licensee, or (3)
       within any other minimum time period imposed by law;
 
           (B) at least five business days before execution of any agreements
       with the Company, each prospective area franchisee, individual
       franchisee, and, if applicable, licensee was provided with a completed
       execution copy of the Company's area franchise agreement, individual
       franchise agreement, or, if applicable, license agreement, respectively,
       together with any related documents (E.G., spousal consent form, phone
       transfer agreement, software license, security agreement, equipment
       lease, national account agreement) with all pertinent specific
       information for such prospective area franchisee, individual franchisee,
       or, if applicable, licensee set forth in those agreements and documents;
 
           (C) each FOC provided to a prospective area franchisee, individual
       franchisee, or, if applicable, licensee complied in all material respects
       at the time of the delivery of such FOC with applicable foreign, federal,
       state, and/or local laws regarding such franchise offering circulars;
 
           (D) each of the Company's required FOCs were either properly
       registered with appropriate franchise regulatory authorities, covered by
       a proper notice filing with appropriate franchise regulatory authorities,
       or qualified for an exemption from such registration or notice filing
       requirements;
 
           (E) each of the Company's offerings were, where applicable, either
       properly registered with appropriate business opportunity sales
       authorities or qualified for an exemption from such registration
       requirements;
 
           (F) the Company obtained signed acknowledgments of receipt for the
       delivery of each FOC to prospective area franchisees, individual
       franchisees, and, if applicable, licensees;
 
           (G) to the extent that the Company may have experienced lapses in one
       or more jurisdictions for its registrations for area franchise offerings,
       individual franchise offerings, and/or, if applicable, license offerings,
       the Company did not offer or sell during the period of any such lapses
       any such area franchises, individual franchises, or, if applicable,
       licenses for franchises (1) in those jurisdictions, (2) to be operated
       outside those jurisdictions by residents of those
 
                                       21
<PAGE>
       jurisdictions, or (3) the sale of which might otherwise have triggered
       the application of the franchise registration laws of those jurisdictions
       during the periods of any such lapse;
 
           (H) to the extent required by foreign, federal, state, and/or local
       law, the Company has complied with all applicable franchise advertising
       filing requirements;
 
           (I) to the best of its knowledge, the Company is not aware of any
       instances in which any of its employees, sales agents, or sales brokers
       for area franchises, individual franchises, or, if applicable, licenses
       provided information to prospective area franchisees, individual
       franchisees, or, if applicable, individual licensees, that materially
       differed from the information contained in the FOCs provided to such
       prospects (including but not limited to "earnings claim" information);
 
           (J) where required, the Company properly filed with appropriate
       franchise regulatory authorities amendments to its FOCs to reflect any
       material changes or developments in the Company's franchise system,
       agreements, operations, financial condition, litigation or other matters
       requiring disclosure;
 
           (K) where required, the Company complied with foreign, federal,
       state, and/or local laws (including in particular those of California and
       North Dakota) requiring registration, disclosure, and/or other compliance
       activities associated with any "material modifications" made to the
       Company's then current area franchises, individual franchises, or, if
       applicable, licenses; and
 
           (L) the Company properly and timely converted the format of its FOCs
       from the prior format prescribed by the Uniform Franchise Offering
       Circular guidelines to the so-called "plain English" guidelines currently
       in effect for FOCs prepared in accordance with Uniform Franchise Offering
       Circular guidelines.
 
        (iv) FRANCHISE AND RELATED LITIGATION. The Company's April 1997 FOCs for
    its universal area franchise agreement and universal individual franchise
    agreement set forth accurate summary information about
 
           (A) any governmental regulatory, criminal, and/or material civil
       actions pending against the Company alleging a violation of a foreign
       and/or United States franchise, antitrust or securities law, fraud,
       unfair or deceptive practices, or comparable allegations as well as
       actions other than ordinary routine litigation incidental to the
       Company's business which are significant in the context of the number of
       the Company's franchisees and the size, nature or financial condition of
       the franchise system or its business operations;
 
           (B) any convictions of a felony, nolo contendre pleas to a felony
       charge, and adverse final judgments in a civil action in foreign
       countries and/or the United States since April 1987 as well as all
       material actions since April 1987 involving violation of a franchise,
       antitrust or securities law, fraud, unfair or deceptive practices, or
       comparable allegations; and
 
           (C) all currently effective injunctive or restrictive orders or
       decrees relating to the franchise area under a foreign, federal, state,
       or local franchise, securities, antitrust, trade regulation, or trade
       practices law resulting from a concluded or pending action or proceeding
       brought by a public agency.
 
In addition, the Company has not received notice of any threatened
administrative, criminal and/or material civil action against it and/or any
persons disclosed in Item II of the Company's April 1997 FOCs for its Universal
Area Franchise Agreement and Universal Individual Franchise Agreement where such
threatened administrative, criminal and/or material civil action alleges a
violation of a foreign and/or United States franchise, antitrust law, or
securities law, fraud, unfair or deceptive practices, or comparable allegations
as well as actions other than ordinary routine litigation incidental to the
Company's business which are significant in the context of the number of the
Company's franchisees and the size, nature, or financial condition of the
franchise system or its business operations.
 
                                       22
<PAGE>
        (v) FRANCHISEE RELATIONS AND OPERATIONS. All expenditures from the
    National Media Fund, which is administered by the Advertising Advisory
    Council (comprised of ten elected domestic franchisee or area franchisee
    representatives and a representative of the Company), are approved by that
    Council and all expenditures from the National Media Fund are authorized
    verbally and in writing by such Council. The Company is not aware of any
    material allegations that any of the expenditures from the National Media
    Fund have been unauthorized by the Advertising Advisory Council, paid to the
    Company for anything other than expressly permitted by the contractual
    provisions associated with the National Media Fund, or was otherwise
    improper. In the Company's communications with its area franchisees,
    individual franchisees, licensees, and representative groups of those area
    franchisees, individual franchisees, and/or licensees, the Company is not
    aware of any material misstatements regarding its operations, franchise
    system, agreements, financial condition, litigation matters, or plans that
    could be used as a basis for a successful fraud, misrepresentation, or
    franchise law violation claim against the Company. The Company has taken and
    continues to take commercially reasonable efforts to protect the
    confidentiality of its current Operations Manual.
 
        (vi) FRANCHISE TERMINATIONS. The Company's termination of or effort to
    terminate or refusal to renew any area franchisee, individual franchisee,
    or, if applicable, licensee, has complied with applicable federal, state,
    and/or local franchise termination laws and regulations including, in
    particular, but not limited to, having provided any such area franchisee,
    individual franchisee, or, if applicable, licensee involved in such a
    nonrenewal or termination any statutorily required notice and opportunity to
    cure. The Company has complied with all other applicable foreign, federal,
    state, and/ or local laws and/or regulations relating to ongoing franchise
    relationships, the termination of such relationships, and/or the non-renewal
    of such relationships.
 
    (w) CONTRACTS.
 
        (i) The Company Disclosure Schedule lists each written or oral contract,
    agreement, arrangement, lease, instrument, mortgage or commitment to which
    the Company or its Subsidiaries is a party or may be bound ("CONTRACT") (A)
    which involves payments by or to the Company or its Subsidiaries of more
    than $200,000 per annum, excluding those Contracts that (x) involve payments
    by franchisees or licensees to the Company, or (y) are between the Company
    (on its own behalf or on behalf of its franchisees) and vendors entered into
    in the ordinary course of business, provided, however, that this exclusion
    shall not apply to any Contract governing material outside vendor
    relationships entered into after April 30, 1996 and not previously filed as
    an exhibit to the SEC Documents; (B) material amendments to any compensation
    agreement or arrangement (including severance agreement or arrangement) with
    any officer, director or 5% stockholder or any former officer or director,
    if such amendment has not previously been filed with the Company's SEC
    Documents; (C) material amendments to franchise agreements, master
    agreements, area agreements or franchise offering circulars; (D)
    international franchise agreements; (E) which is an arrangement limiting or
    restraining the Company or any subsidiary or any successor thereto from
    engaging or competing in any manner or in any business; (F) under which the
    Company or any subsidiary guarantees the payment or performance by others or
    in any way is or will be liable with respect to obligations of any other
    person; or (G) which is a material arrangement not made in the ordinary
    course of business.
 
        (ii) There have been filed as exhibits to, or incorporated by reference
    in, the Form 10-K of the Company for the year ended April 30, 1996 all
    Contracts which, as of the date hereof, are material as described in Item
    601(b)(10) of Regulation S-K.
 
        (iii) All Contracts are valid and binding and in full force and effect
    on the date of this Agreement except to the extent they have previously
    expired in accordance with their terms. None of the Company, the
    subsidiaries nor, to the Company's knowledge, any other parties, have
    violated any provision of, or committed or failed to perform any act which
    with notice, lapse of time or both would constitute a default under the
    provisions of, any Contract, the termination or violation of which, or the
 
                                       23
<PAGE>
    default under which, could reasonably be expected to have a material adverse
    effect on the Company. True and complete copies of all Contracts listed on
    the Company Disclosure Schedule or listed in the Form 10-K of the Company
    for the year ended April 30, 1996, together with all amendments thereto,
    have been delivered to Parent.
 
    SECTION 3.2 REPRESENTATIONS AND WARRANTIES OF PARENT. Except as set forth on
the disclosure schedule (provided that an item on such disclosure schedule shall
be deemed to qualify only the particular subsection or subsections of this
Section 3.2 specified for such item) delivered by Parent to the Company prior to
the execution of this Agreement (the "PARENT DISCLOSURE SCHEDULE"), Parent
represents and warrants to the Company as follows:
 
    (a) ORGANIZATION, STANDING AND CORPORATE POWER. Parent is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Delaware and has the requisite corporate power and authority to carry on its
business as now being conducted. Parent is duly qualified or licensed to do
business and is in good standing in each jurisdiction in which the nature of its
business or the ownership or leasing of its properties makes such qualification
or licensing necessary, other than in such jurisdictions where the failure to be
so qualified or licensed would not, individually or in the aggregate, have a
material adverse effect on Parent.
 
    (b) CAPITAL STRUCTURE. The authorized capital stock of Parent consists of
500,000,000 shares of Parent Common Stock, and 500,000 shares of preferred
stock, $.001 par value per share ("PARENT PREFERRED STOCK"). No shares of Parent
Preferred Stock are outstanding on the date of this Agreement. At the close of
business on April 26, 1997, (i) 69,652,669 shares of Parent Common Stock were
issued and outstanding, (ii) no shares of Parent Common Stock were held by
Parent in its treasury, (iii) 7,588,774 shares of Parent Common Stock were
reserved for issuance upon exercise of outstanding options to purchase shares of
Parent Common Stock granted to employees of or consultants to Parent or its
subsidiaries or affiliates under the terms of Parent's 1994 Amended and Restated
Long-Term Incentive Compensation Plan (the "PARENT STOCK OPTION PLAN"), (iv)
9,896,181 shares of Parent Common Stock were reserved for issuance upon exercise
of Parent's outstanding convertible subordinated notes, as described in Parent
SEC Documents (as defined below), (v) 500,000 shares of Parent Common Stock were
reserved or available for issuance under the terms of the Parent's Employee
Stock Purchase Plan, as described in the Parent SEC Documents, (vi) 750,000
shares of Parent Common Stock were reserved or available for issuance under the
terms of the Parent's 1996 Non-Employee Directors' Stock Plan, as described in
the Parent SEC Documents, and (vii) the number of shares of Parent Common Stock
available for issuance upon exercise of options issued under the terms of the
Parent Stock Option Plan automatically increases to 20% of the total number of
issued and outstanding shares of Parent Common Stock, as described in the Parent
SEC Documents. Except as set forth above, at the close of business on April 26,
1997, no shares of capital stock or other voting securities of the Parent were
issued, reserved for issuance or outstanding, and since April 26, 1997 until the
date hereof no shares of capital stock or other voting securities have been
issued by Parent except (y) upon the exercise of options or other rights
outstanding at April 26, 1997 under the plans listed in the third sentence of
this subsection (b), and (z) the issuance of not more than 56,769 shares of
Parent Common Stock in connection with acquisitions. All outstanding shares of
capital stock of Parent are, and all shares which may be issued pursuant to this
Agreement will be, when issued, duly authorized, validly issued, fully paid and
nonassessable and not subject to preemptive rights. Except for the Convertible
Subordinated Notes due 2001 and the Convertible Subordinated Notes due 2003 as
described in the Parent SEC Documents, there are no bonds, debentures, notes or
other indebtedness of Parent having the right to vote (or convertible into, or
exchangeable for, securities having the right to vote) on any matters on which
stockholders of Parent may vote. Except as set forth above, as of the date of
this Agreement, there are no outstanding securities, options, warrants, calls,
rights, commitments, agreements, arrangements or undertakings of any kind to
which Parent is a party or by which it is bound obligating Parent to issue,
deliver or sell, or cause to be issued, delivered or sold, additional shares of
capital stock or other voting securities of Parent or obligating Parent to
issue, grant, extend or enter into any such security, option, warrant, call,
 
                                       24
<PAGE>
right, commitment, agreement, arrangement or undertaking, except for options and
other equity compensation granted by Parent with respect to no more than
4,000,000 shares of Parent Common Stock since April 26, 1997. There are no
outstanding contractual obligations of Parent to repurchase, redeem or otherwise
acquire any shares of capital stock of Parent. As of the date of this Agreement,
the authorized capital stock of Sub consists of 1,000 shares of common stock, no
par value per share, of which 100 shares have been validly issued, all of which
are fully paid and nonassessable and are owned by Parent free and clear of any
Liens.
 
    (c) AUTHORITY; NONCONTRAVENTION.
 
        (i) Parent and Sub have the requisite corporate power and authority to
    enter into this Agreement and to consummate the transactions contemplated by
    this Agreement. The execution and delivery of this Agreement and the
    consummation of the transactions contemplated by this Agreement have been
    duly authorized by all necessary corporate action on the part of Parent and
    Sub. This Agreement has been duly executed and delivered by Parent and Sub
    and constitutes a valid and binding obligation of each such party,
    enforceable against each such party in accordance with its terms, except to
    the extent such enforcement may be limited by applicable bankruptcy,
    reorganization, moratorium, or other law. The execution and delivery of this
    Agreement does not, and the consummation of the transactions contemplated by
    this Agreement and compliance with the provisions of this Agreement will
    not, conflict with, or result in any violation of, or default (with or
    without notice or lapse of time, or both) under, or give rise to a right of
    termination, cancellation or acceleration of any obligation or to loss of
    any benefit under, or result in the creation of any Lien upon any of the
    properties or assets of Parent or any of its subsidiaries under, (i) the
    articles incorporation or bylaws of Parent or Sub or the comparable charter
    or organizational documents of any other subsidiary of Parent, (ii) any loan
    or credit agreement, note, bond, mortgage, indenture, lease or other
    agreement, instrument, permit, concession, franchise or license applicable
    to Parent or any of its subsidiaries or their respective properties or
    assets or (iii) subject to the governmental filings and other matters
    referred to in the following sentence, any judgment, order, decree,
    injunction, statute, law, ordinance, rule or regulation applicable to Parent
    or any of its subsidiaries or their respective properties or assets, other
    than, in the case of clause (ii), any such conflicts, violations or defaults
    that would not, individually or in the aggregate, have a material adverse
    effect on Parent.
 
        (ii) No consent, approval, order or authorization of, or registration,
    declaration or filing with any Governmental Entity is required by Parent or
    any of its subsidiaries in connection with the execution and delivery of
    this Agreement or the consummation by Parent or Sub, as the case may be, of
    any of the transactions contemplated by this Agreement, except for (A) the
    filing with the Specified Agencies of a premerger notification and report
    form under the HSR Act, (ii) the filing with the SEC of (1) the Form S-4 and
    (2) such reports under Sections 13(a), 13(d) and 16(a) of the Exchange Act
    as may be required in connection with this Agreement and the transactions
    contemplated by this Agreement, (C) the filing of the Merger Documents with
    the California Secretary of State and appropriate documents with the
    relevant authorities of other states, as required under applicable law, and
    (D) such other consents, approvals, orders, authorizations, registrations,
    declarations and filings, including under (1) the laws of any foreign
    country in which the Company or any of its subsidiaries conducts any
    business or owns any property or assets or as otherwise required under
    applicable foreign law or (2) the "takeover" or "blue sky" laws of various
    states, the failure of which to be obtained or made would not, individually
    or in the aggregate, have a material adverse effect on Parent or prevent or
    materially delay the consummation of any of the transactions contemplated by
    this Agreement.
 
    (d) SEC DOCUMENTS; FINANCIAL STATEMENTS. Parent has filed with the SEC all
required reports and forms and other documents required to be filed by it
pursuant to relevant United States securities statutes, regulations, policies
and rules (the "PARENT SEC DOCUMENTS"), all of which have complied in all
material respects with all applicable requirements of such statutes,
regulations, policies and rules. As of their
 
                                       25
<PAGE>
respective dates, none of the Parent SEC Documents, except as revised or
superseded by a later filed Parent SEC Document, without regard to any
amendments or filings after the date hereof, contained any untrue statement of a
material fact or omitted to state a material fact required to be stated therein
or necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading. In addition, nothing
has come to the attention of Parent since the date any Parent SEC Document was
filed that would have made, as of the filing date, any statement in any Parent
SEC Document untrue in a material respect, or that, if omitted to be stated as
of the filing date, would have made the statements in such Parent SEC Document,
in light of the circumstances under which they were made, misleading. Except to
the extent that information contained in any Parent SEC Document has been
revised or superseded by a later-filed Parent SEC Document filed and publicly
available prior to the date of this Agreement, none of the Parent SEC Documents
contains any untrue statement of a material fact or omits to state any material
fact required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading. The financial statements of Parent included in the Parent SEC
Documents have been prepared in accordance with generally accepted accounting
principles (except, in the case of unaudited statements, as permitted by Form
10-Q of the SEC) applied on a consistent basis during the periods involved
(except as may be indicated in the notes thereto) and fairly present the
consolidated financial position of Parent and its consolidated subsidiaries as
of the dates thereof and the consolidated results of their operations and cash
flows for the periods then ended (subject, in the case of unaudited statements,
to the omission of footnote information and normal year-end adjustments).
 
    (e) INFORMATION SUPPLIED. None of the information supplied or to be supplied
by Parent or Sub for inclusion or incorporation by reference in (i) the Form S-4
will, at the time the Form S-4 is filed with the SEC, at any time it is amended
or supplemented or at the time it becomes effective under the Securities Act,
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary to make the statements therein,
in light of the circumstances under which they are made, not misleading or (ii)
the Proxy Statement will, at the date the Proxy Statement is first mailed to the
Company's Stockholders or at the time of the Company Stockholders' Meeting,
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they are made, not
misleading. The Form S-4 will comply as to form in all material respects with
the requirements of the Securities Act and the rules and regulations promulgated
thereunder, except that no representation or warranty is made by Parent or Sub
with respect to statements made or incorporated by reference in either the Form
S-4 or the Proxy Statement based on information supplied by the Company
specifically for inclusion or incorporation by reference therein.
 
    (f) FINANCIAL ADVISORS. No financial advisor, investment banker, broker or
other person is entitled to any financial advisor's, finder's or other similar
fee or commission in connection with the transactions contemplated by this
Agreement based upon arrangements made by or on behalf of Parent.
 
    (g) ACCOUNTING MATTERS. Neither Parent nor any of its affiliates has taken
or agreed to take any action or is aware of any condition that would prevent
Parent from accounting for the business combination to be effected by the Merger
as a pooling-of-interests.
 
    (h) POOLING OPINION. Parent's Board of Directors has received a written
opinion from Price Waterhouse LLP that, in accordance with generally accepted
accounting principles and applicable rules and regulations of the SEC, Parent is
a poolable entity and the Merger should be treated as a "pooling of interests"
for accounting purposes (the "PARENT POOLING OPINION").

    SECTION 4.2  NO INCONSISTENT ACTIVITIES.  In light of the consideration
given by the Board of Directors of the Company prior to the execution of this
Agreement to, among other things, the transactions contemplated hereby, and in
light of advice received from the Company's financial advisors, the Company
agrees that it shall (a) terminate any existing discussions and/or negotiations
with other parties concerning the potential acquisition of the Company or any
other transaction that would be inconsistent with the transactions contemplated
hereby, and (b) not, nor shall it permit any of its subsidiaries to, nor shall
it authorize or permit any officer, director or employee of, or any investment
banker, attorney or other advisor or representative of, the Company or any of
its subsidiaries to, directly or indirectly, solicit or initiate, or encourage
the submission of, any Takeover Proposal (as defined below), or participate in
any discussions or negotiations regarding, or furnish to any person any

Directors from furnishing information to or entering into discussions or
negotiations with any person or entity that makes an unsolicited bona fide
proposal to acquire the Company pursuant to a merger, consolidation, share

or other similar transaction, if, and only to the extent that, (i) the Company's
Board of Directors determines in good faith, after considering applicable law
and receiving the written advice of outside counsel, that such action is
required by its fiduciary duties to the Company's Stockholders under applicable
law, (ii) the Company's Board of Directors determines in good faith, after
receiving the written advice of its financial advisors, that such unsolicited

(iii) prior to furnishing such information to, or entering into discussions or
negotiations with, such person or entity, the Company provides written notice to
Parent to the effect that it is furnishing information to, or entering into
discussions or negotiations with, such person or entity and receives from such
person or entity an executed confidentiality agreement in reasonably customary
form. The Company shall notify Parent orally and in writing of any inquiries,
offers or proposals with respect to a Takeover Proposal (including without
limitation the terms and conditions of any such proposal, the identity of the
person making it and all other information reasonably requested by Parent),
within 24 hours of the receipt thereof, shall keep Parent
 
                                       28
<PAGE>

of, the Company or any of its subsidiaries, other than the transactions
contemplated by this Agreement. Neither the Company nor any of its subsidiaries
shall, directly or indirectly, release any third party from any confidentiality
agreement. Nothing contained herein shall prohibit the Company or its Board of
Directors from disclosing to its stockholders a position as contemplated by Rule

Proposal by means of a tender offer.

    (a) As promptly as reasonably practicable after the execution of this
Agreement, (i) the Company shall prepare and file with the SEC a proxy statement
relating to the meeting of the Company's stockholders to be held to obtain the
Company Stockholder Approval (together with any amendments thereof or
supplements thereto, the "PROXY STATEMENT") and (ii) Parent shall prepare and
file with the SEC a registration statement on Form S-4 (together with all
amendments thereto, the "FORM S-4") in which the Proxy Statement shall be
included as a prospectus, in connection with the registration under the
Securities Act of the shares of Parent Common Stock to be issued to the
stockholders of the Company pursuant to the Merger. Each of Parent and the
Company shall use all reasonable efforts to cause the Form S-4 to become

under any applicable federal or state securities laws in connection with the
issuance of shares of Parent Common Stock pursuant to the Merger. Each of Parent
and the Company shall furnish all information concerning itself to the other as
the other may reasonably request in connection with such actions and the
preparation of the Form S-4 and Proxy Statement. The Company authorizes Parent
to utilize in the Form S-4 and in all such state filed materials, the
information concerning the Company and its subsidiaries provided to Parent in
connection with, or contained in, the Proxy Statement. Parent promptly will
advise the Company when the Form S-4 has become effective and of any supplements
or amendments thereto, and the Company shall not distribute any written material
that would constitute, as advised by counsel to the Company, a "prospectus"
relating to the Merger or the Parent Common Stock within the meaning of the
Securities Act or any applicable state securities law without the prior written
consent of Parent. As promptly as practicable after the Form S-4 shall have
become effective, the Company and Parent shall mail the Proxy Statement to the
Company's stockholders.
 
    (b) Parent agrees promptly to advise the Company if at any time prior to the
meeting of stockholders of the Company to approve the Merger any information
provided by it in the Proxy Statement is or becomes incorrect or incomplete in
any material respect and to provide the Company with the information needed to

applicable law after the mailing thereof to the stockholders of the Company.
 
    (c) The Company agrees promptly to advise Parent if at any time prior to the
meeting of its stockholders any information provided by it in the Proxy
Statement is or becomes incorrect or incomplete in any material respect and to
provide Parent with the information needed to correct such inaccuracy or
omission. The Company will furnish Parent with such supplemental information as
may be necessary in
 
                                       29
<PAGE>
order to cause the Proxy Statement, insofar as it relates to the Company and its
subsidiaries, to comply with applicable law after the mailing thereof to
stockholders of the Company.
 
    (d) As soon as reasonably practicable following the date of this Agreement,
the Company shall call and hold a meeting of its stockholders (the "COMPANY
STOCKHOLDERS' MEETING") for the purpose of obtaining the Company Stockholder
Approval. The Company shall use its best efforts to solicit from its
stockholders proxies, and shall take all other action necessary or advisable to
secure the vote or consent of stockholders required by applicable law or
otherwise to obtain the Company Stockholder Approval and through its Board of
Directors shall (subject to their fiduciary duties) recommend to its
stockholders the giving of the Company Stockholder Approval.
 
    SECTION 5.2  ACCESS TO INFORMATION; CONFIDENTIALITY.  Each of the Company

access during normal business hours during the period prior to the Effective
Time to all their respective properties, books, contracts, commitments,
personnel and records and, during such period, each of the Company and Parent

to the other party, (a) a copy of each report, schedule, registration statement
and other document filed by it during such period pursuant to the requirements
of federal or state securities laws and (b) all other information concerning its
business, properties and personnel as such other party may reasonably request.

will hold, and will cause its respective officers, employees, accountants,
counsel, financial advisers and other representatives and affiliates to hold,
any confidential information in accordance with the Confidentiality Agreement
dated February 28, 1997, between Parent and the Company (the "CONFIDENTIALITY
AGREEMENT").
 
    SECTION 5.3  REASONABLE EFFORTS; NOTIFICATION.
 
    (a) Upon the terms and subject to the conditions set forth in this
Agreement, each of the parties agrees to use reasonable efforts to take, or
cause to be taken, all actions, and to do, or cause to be done, and to assist
and cooperate with the other parties in doing, all things necessary, proper or
advisable to consummate and make effective, in the most expeditious manner
practicable, the Merger and the other transactions contemplated by this
Agreement, including (i) the making of all necessary registrations and filings
(including filings with Governmental Entities, if any), (ii) the obtaining of
all necessary consents, approvals or waivers from third parties and (iii) the
execution and delivery of any additional instruments necessary to consummate the
transactions contemplated by, and to fully carry out the purposes of, this
Agreement.
 
    (b) the Company shall give prompt written notice to Parent, and Parent shall
give prompt written notice to the Company, of (i) any representation or warranty
made by it contained in this Agreement that is qualified as to materiality
becoming untrue or any such representation or warranty that is not so qualified
becoming untrue in any material respect or (ii) the failure by it to comply with
or satisfy any covenant, condition or agreement to be complied with or satisfied
by it under this Agreement; provided, however, that no such notification shall
affect the representations, warranties, covenants or agreements of the parties
or the conditions to the obligations of the parties under this Agreement.
 
    SECTION 5.4  STOCK OPTION PLANS.
 
    (a) As soon as practicable following the date of this Agreement, the Board
of Directors of the Company (or, if appropriate, any committee administering the
Stock Option/Purchase Plans (as defined below)) shall adopt such resolutions or
take such other actions as are required, if any, to adjust the terms of all
outstanding stock options to purchase shares of the Company Common Stock ("STOCK
OPTIONS") heretofore granted under any stock option, stock purchase, restricted
stock unit or stock appreciation rights plan, program or arrangement of the
Company, including, without limitation, the Restated 1985 Stock Option Plan, the
Santa Fe 1995 Employee Stock Option Plan, and the Santa Fe 1995 Stock Option
 
                                       30
<PAGE>
Plan for Non-Employee Directors (collectively, the "STOCK OPTION/PURCHASE
PLANS") as is necessary to provide that each Stock Option outstanding
immediately prior to the Effective Time, whether or not then exercisable, shall
be immediately converted as of the Effective Time into the right to purchase
from Parent the Option Conversion Number (as defined below) of shares of Parent
Common Stock (each, an "ADJUSTED OPTION"). Each Adjusted Option will have
substantially the same terms as the Stock Option to which it is related,
including the same vesting schedule (other than to the extent accelerated
pursuant to the terms of such Stock Option, Stock Option/Purchase Plans or in
accordance with the present terms of any employment agreements existing on the
date hereof, which Stock Option shall remain exercisable following the Effective
Time in accordance with the provisions of the Stock Option Plan under which
granted), except for its exercise price and the number and kind of shares
subject thereto. The exercise price of any Adjusted Option (the "ADJUSTED
EXERCISE PRICE") shall be an amount equal to the exercise price of the Stock
Option related to such Adjusted Option as of the date of this Agreement divided
by the Exchange Ratio. The "OPTION CONVERSION NUMBER" for any Adjusted Option
shall be equal to the number of shares purchasable pursuant to the Stock Option
related to such Adjusted Option as of the date of this Agreement multiplied by
the Exchange Ratio. No certificates or scrip representing fractional shares of
Parent Common Stock shall be issued upon the exercise of any Adjusted Option,
and no fractional share interest will entitle the owner thereof to vote or to
any rights of a stockholder of Parent. Each holder of any Adjusted Option who
exercises such Adjusted Option in accordance with its terms and this Agreement
who would otherwise have been entitled to receive a fraction of a share of
Parent Common Stock (after taking into account all Adjusted Options delivered by
such holder on the date such Adjusted Options are exercised) shall receive, in
lieu thereof, cash (without interest) in an amount equal to such fractional part
of a share of Parent Common Stock multiplied by the closing price of Parent
Common Stock on the Nasdaq National Market System (as reported by THE WALL
STREET JOURNAL or, if not reported thereby, any other authoritative source) on
the trading date immediately preceding the date such Adjusted Options are
exercised.
 
    (b) Parent agrees to take such actions as are necessary for the conversion
of such Stock Options of the Company pursuant to Section 5.4(a) into Adjusted
Options, including the reservation, issuance and listing of Parent Common Stock.
 
    (c) A holder of an Adjusted Option may exercise such Adjusted Option in
whole or in part in accordance with its terms by delivering a properly executed
notice of exercise to Parent, together with the consideration therefor and the
federal withholding tax information, if any, required in accordance with the
related Stock Option Plan.
 
    SECTION 5.5  CONVEYANCE TAXES.  Parent and the Company shall cooperate in
the preparation, execution and filing of all returns, questionnaires,
applications or other documents regarding any real property transfer or gains,
sales, use, transfer, value added, stock transfer and stamp taxes, any transfer,
recording, registration and other fees, and any similar taxes which become
payable by Parent or the Company in connection with the transactions
contemplated hereby that are required or permitted to be filed on or before the
Effective Time. All of such taxes and expenses shall be borne by Parent.
 
    SECTION 5.6  INDEMNIFICATION, EXCULPATION AND INSURANCE.
 
    (a) The articles of incorporation and the bylaws of the Surviving
Corporation shall contain the provisions with respect to indemnification and
exculpation from liability set forth in the Company's articles of incorporation
and bylaws on the date of this Agreement, which provisions shall not be amended,
repealed or otherwise modified for a period of six years from the Effective Time
in any manner that would adversely affect the rights thereunder of individuals
who on or prior to the Effective Time were directors, officers, employees or
agents of the Company, unless such modification is required by law. Parent
hereby unconditionally and irrevocably guarantees for the benefit of the
Company's directors and officers the obligations of the Company and the
Surviving Corporation under the foregoing indemnification arrangements,
including any such existing indemnification agreements to which the Company is a
party; provided,
 
                                       31
<PAGE>
however, that in no event shall the amount of such guarantee exceed an amount
permitted for such a guarantee under the terms of Parent's credit agreement.
 
    (b) If Parent, the Surviving Corporation or any of their successors or
assigns (i) consolidates with or merges into any other person and shall not be
the continuing or surviving corporation or entity of such consolidation or
merger or (ii) transfers all or substantially all of its properties and assets
to any person, then and in each such case, proper provisions shall be made so
that the successors and assigns of Parent or the Surviving Corporation, as the
case may be, shall assume the obligations set forth in this Section 5.6.
 
    (c) Parent shall, to the fullest extent permitted by applicable law,
indemnify and defend (and bear all costs and expenses, including without
limitation reasonable attorneys' fees and costs, associated therewith) each
officer and director of the Company serving as such immediately before the
Effective Time for and against any and all claims, damages and losses relating
to or arising out of (i) their performance of their respective Company duties
prior to the Effective Time, or (ii) the consummation of any of the transactions
contemplated in this Agreement Parent shall cause the Surviving Corporation to
provide officers' and directors' liability insurance in respect of acts or
omissions occurring prior to the Effective Time covering each such person
currently covered by the Company's officers' and directors' liability insurance
policy on terms with respect to coverage and amount no less favorable than those
of such policy in effect on the date hereof (or, if such insurance policy cannot
be obtained, such insurance policy on terms with respect to coverage and amount
as favorable as can be obtained, subject to the proviso at the conclusion of
this sentence), provided, however, that the aggregate cost of such insurance
over such four-year period shall not exceed the product of four multiplied by
the premium cost for such policy during the year ended April 30, 1997.
 
    SECTION 5.7  FEES AND EXPENSES.  Except as provided in Section 7.5, whether
or not the Merger is consummated, all costs and expenses incurred in connection
with this Agreement and the transactions contemplated hereby shall be paid by
the party incurring such expenses, except that those expenses incurred in
connection with printing and mailing the Proxy Statement and Form S-4, will be
shared equally by Parent and the Company.
 
    SECTION 5.8  PUBLIC ANNOUNCEMENTS.  Parent and Sub, on the one hand, and the
Company, on the other hand, will consult with each other before issuing, and
provide each other the opportunity to review and comment upon, any press release
or other public statements with respect to the transactions contemplated by this
Agreement, including the Merger, and shall not issue any such press release or
make any such public statement prior to such consultation, except as may be
required by applicable law, court process or by obligations pursuant to any
listing agreement with any national securities exchange.
 
    SECTION 5.9  AFFILIATES; ACCOUNTING AND TAX TREATMENT.
 
    (a) The Company shall (i) promptly deliver to Parent a letter identifying
all persons who may be deemed affiliates of the Company under Rule 145 of the
Securities Act or otherwise under applicable SEC accounting releases with
respect to pooling-of-interests accounting treatment and (ii) at least 30 days
prior to the Effective Time obtain (if not previously obtained) from each such
affiliate a written agreement substantially in the form of Exhibit 5.9 hereto.
The Company shall obtain such a written agreement as soon as practicable from
any person who may be deemed to have become an affiliate of the Company after
the Company's delivery of the letters referred to in clause (i) above and prior
to the Effective Time.
 
    (b) Promptly after the date hereof, Parent shall provide the Company with
information regarding Parent's compliance procedures for ensuring that those
persons deemed to be affiliates of Parent under Rule 145 of the Securities Act
or otherwise under applicable SEC accounting releases with respect to
pooling-of-interests accounting treatment are required to abide by those
restrictions on transactions involving their shares of Parent Common Stock (or
securities convertible into, or exercisable for, shares of Parent Common Stock)
that are necessary to preserve the Merger's qualification for
pooling-of-interests accounting treatment. If the Company, after consultation
with its outside legal and financial advisors
 
                                       32
<PAGE>
reasonably concludes that supplemental assurances are necessary to permit the
satisfaction of any of the other covenants or any of the conditions precedent
set forth in the Agreement, then Parent shall cooperate with the Company to
implement mutually acceptable supplemental arrangements, including without
limitation, obtaining written affiliate agreements from Parent's affiliates
substantially in the form of Exhibit 5.9 attached hereto.
 
    (c) Each party hereto shall use its best efforts to (i) cause the Merger to
qualify, and shall not take any actions which could prevent the Merger from
qualifying, for pooling-of-interests accounting treatment and as a
reorganization under the provisions of Section 368(a) of the Code, and (ii)
obtain the opinions of counsel referred to in Section 6.3(c).

                       TERMINATION, AMENDMENT AND WAIVER
 
    SECTION 7.1  TERMINATION.  This Agreement may be terminated at any time
prior to the Effective Time, whether before or after approval by the
stockholders of the Company or of Parent:
 
    (a) by mutual written consent of Parent and the Company;
 
    (b) by Parent (provided that Parent is not then in material breach of any
representation, warranty, covenant or other agreement contained herein), upon a
breach of any representation, warranty, covenant or agreement on the part of the
Company set forth in this Agreement, or if any representation or warranty of the
Company shall have become untrue, in either case such that the conditions set
forth in Section 6.2(a) or Section 6.2(b), as the case may be, would be
incapable of being satisfied by October 31, 1997; provided that, in any case, a
willful breach shall be deemed to cause such conditions to be incapable of being
satisfied for purposes of this Section 7.1(b);
 
    (c) by the Company (provided that the Company is not then in material breach
of any representation, warranty, covenant or other agreement contained herein),
upon a breach of any representation, warranty, covenant or agreement on the part
of Parent set forth in this Agreement, or if any representation or warranty of
Parent shall have become untrue, in either case such that the conditions set
forth in Section 6.3(a) or Section 6.3(b), as the case may be, would be
incapable of being satisfied by October 31, 1997; provided that, in any case a
willful breach shall be deemed to cause such conditions to be incapable of being
satisfied for purposes of this Section 7.1(c);
 
    (d) by either Parent or the Company, if any Governmental Entity shall have
issued an order, decree, injunction or ruling or taken any other action
permanently enjoining, restraining or otherwise prohibiting the consummation of
the Merger and such order, decree, injunction or ruling or other action shall
have become final and nonappealable;
 
    (e) by either Parent or the Company, if the Merger shall not have occurred
by October 31, 1997, unless the failure to consummate the Merger is the result
of a breach of a covenant set forth in this Agreement or a willful and material
breach of any representation or warranty set forth in this Agreement by the
party seeking to terminate this Agreement;
 
    (f) by either Parent or the Company (provided that if the terminating party
is the Company, the Company shall not be in material breach of any of its
obligations hereunder), if the approval of the stockholders of the Company
required for the consummation of the Merger shall not have been obtained by
reason of the failure to obtain the required vote at a duly held meeting of the
Company's stockholders or at any adjournment or postponement thereof;
 
    (g) by the Company, prior to the approval of the Merger by its stockholders,
upon five business days' prior notice to Parent, if, as a result of a Superior
Proposal by a party other than Parent or any of its
 
                                       35
<PAGE>
affiliates, the Company's Board of Directors determines in good faith that their
fiduciary obligations under applicable law require that such Superior Proposal
be accepted; provided, however, that (i) the Company's Board of Directors shall
have concluded in good faith, after considering provisions of applicable law and
after giving effect to all concessions which may be offered by Parent pursuant
to clause (ii) below, after receiving the written advice of outside counsel,
that such action is required by its fiduciary duties to the Company's
Stockholders under applicable law and (ii) prior to any such termination and
prior to accepting, or entering into any agreement regarding, the Superior
Proposal the Company shall provide Parent (for at least the five business days
following the receipt of the notice) an opportunity to amend this Agreement to
provide for terms substantially similar to those included in the Superior
Proposal, and in addition the Company shall, and shall cause its respective
financial and legal advisors to, negotiate in good faith with Parent to make
such adjustments in the terms and conditions of this Agreement as would enable
the Company to proceed with the transactions contemplated hereby. In the event
that Parent, in its sole discretion, determines to amend this Agreement as
provided above, then the Company shall enter into such amendment and shall not
enter into any agreement regarding the specific Superior Proposal under
consideration;
 
    (h) by Parent, if the Board of Directors of the Company (or any committee
thereof) (i) withdraws or modifies adversely its approval and recommendation of
the Merger or this Agreement, (ii) within ten days after Parent's request, shall
fail to reaffirm such approval or recommendation, (iii) shall approve or
recommend any Takeover Proposal, other than with Parent or an affiliate thereof,
or a Tender Offer or Exchange Offer for 15% or more is commenced and the
Company's Board of Directors fails to recommend against acceptance of such
Tender Offer or Exchange Offer, (iv) shall resolve to take any of the actions
specified in this Section 7.1(h); or (v) fails to call and hold the Company
Stockholder's Meeting within forty (40) days after the SEC declares the Form S-4
effective; provided, however, that the disclosure by the Company of only the
existence and terms of a Takeover Proposal, which disclosure includes a
reaffirmation of the approval and recommendation of the Company's Board of
Directors with respect to the Merger and this Agreement as described in Section
3.1(d)(iii) hereof, shall not constitute a withdrawal or adverse modification
within the meaning of clause (i) of this subsection (h); or
 
    (i) by the Company, if the Share Value would be less than $23.00 per share
unless Parent, within three days after receipt of written notice by the Company
of its intention to so terminate, shall have elected to adjust the Exchange
Ratio pursuant to the fourth sentence of Section 2.1(c) hereof.
 
    SECTION 7.2  EFFECT OF TERMINATION.  In the event of termination of this
Agreement by either the Company or Parent as provided in Section 7.1, this
Agreement shall forthwith become void and have no effect, without any liability
or obligation on the part of Parent, Sub or the Company or their respective
officers or directors, except as set forth in Section 3.1(p), Section 5.7 and
Section 7.5, which Sections shall survive termination, and except to the extent
that such termination results from the willful and material breach by a party of
any of its representations, warranties, covenants or agreements set forth in
this Agreement.
 
    SECTION 7.3  AMENDMENT.  This Agreement may be amended by the parties at any
time before or after approval hereof by the stockholders of the Company;
provided, however, that after such stockholder approval there shall not be made
any amendment that by law requires further approval by the stockholders of the
Company without the further approval of such stockholders as required by law.
This Agreement may not be amended except by an instrument in writing signed on
behalf of all of the parties.
 
    SECTION 7.4  EXTENSION; WAIVER.  At any time prior to the Effective Time,
the parties may (a) extend the time for the performance of any of the
obligations or other acts of the other parties, (b) waive any inaccuracies in
the representations and warranties contained in this Agreement or in any
document delivered pursuant to this Agreement or (c) subject to the proviso of
Section 7.3, waive compliance with any of the agreements or conditions contained
in this Agreement. Any agreement on the part of a party to any such extension or
waiver shall be valid only if set forth in an instrument in writing,
 
                                       36
<PAGE>
signed on behalf of such party. The failure of any party to this Agreement to
assert any of its rights under this Agreement or otherwise shall not constitute
a waiver of those rights.
 
    SECTION 7.5  TERMINATION FEE.  (a) In the event that (i) the Company
terminates this Agreement pursuant to Section 7.1(g), Parent terminates this
Agreement pursuant to Section 7.1(h) or Parent terminates this Agreement as a
result of the Company's material breach of Section 4.2, or (ii) Parent or the
Company terminates this Agreement pursuant to Section 7.1(e) and within six
months after such termination the Company shall have entered into a definitive
agreement with any person (other than Parent or any of its affiliates) regarding
a Takeover Proposal, or (iii) Company Stockholder Approval is not received and
at the time of such termination or prior to the Company Stockholders' Meeting
there shall have been a Takeover Proposal (whether or not such Takeover Proposal
shall have been rejected or shall have been withdrawn prior to the time of such
termination or of the Company Stockholders' Meeting), and the Company shall have
entered into a definitive agreement with any person (other than Parent or any of
its affiliates) with any person within one year of termination then the Company
shall pay to Parent (by wire transfer of immediately available funds, and as a
condition to termination in the case of a termination pursuant to Section
7.1(g)) a cash termination fee in an aggregate amount equal to (A) 3% of the
product of the number of outstanding shares of Company Common Stock on a fully
diluted basis (as though all options or other securities convertible into or
exercisable or exchangeable for shares of Company Common Stock had been so
converted, exercised or exchanged) on the date hereof, multiplied by $24.50, or,
(B) if greater and if the Company enters into a definitive agreement with
respect to a Takeover Proposal within six months following termination of this
Agreement under Section 7.1(e), Section 7.1(f), Section 7.1(g), or Section
7.1(h), then 3% of the product of the number of outstanding shares of Company
Common Stock on a fully diluted basis (as though all options or other securities
convertible into or exercisable or exchangeable for shares of Company Common
Stock had been so converted, exercised or exchanged) on the date such definitive
agreement is executed, multiplied by the value per share of Company Common Stock
of the consideration to be paid in such Takeover Proposal. If the Company is
obligated to pay such termination fee pursuant to clause (i) of the preceding
sentence, then the Company shall pay on account of such fee on the date of
termination of this Agreement the fee calculated under clause (A) of the
immediately preceding sentence, and, if the Company subsequently enters into a
definitive agreement with respect to a Takeover Proposal within six months
following termination of this Agreement, the Company shall immediately pay to
Parent the amount, if any, by which the termination fee calculated under clause
(B) of the immediately preceding sentence exceeds the termination fee calculated
under clause (A) of the immediately preceding sentence.
 
    (b) Upon the termination of this Agreement for one of the reasons set forth
in Section 7.5(a), the Company shall pay to Parent (by wire transfer of
immediately available funds), and as a condition to termination in the case of a
termination pursuant to Section 7.1(g) hereof, a cash amount equal to 1% of the
product of the number of outstanding shares of Company Common Stock on a fully
diluted basis (as though all options or other securities convertible into or
exercisable or exchangeable for shares of Company Common Stock had been so
converted, exercised or exchanged) on the date hereof multiplied by $24.50 at
the time of termination, to cover Parent's and Sub's legal, accounting,
printing, investment banking and other costs, expenses and fees incurred in
connection with the transactions contemplated by this Agreement.
 
    (c) Upon the termination of this Agreement because Company Stockholder
Approval is not received and at the time of such termination or prior to the
Company Stockholders' Meeting there shall have been a Takeover Proposal, the
Company shall pay to Parent (by wire transfer of immediately available funds)
the amount set forth in Section 7.5(b) hereof, plus an amount equal to one-half
of 1% of the product of the number of outstanding shares of Company Common Stock
on a fully diluted basis (as though all options or other securities convertible
into or exercisable or exchangeable for shares of Company Common Stock had been
so converted, exercised or exchanged) on the date hereof multiplied by $24.50 at
the time of termination. If the fee required to be paid by this subsection (c)
has been paid and thereafter the Company
 
                                       37
<PAGE>
is required to pay amounts under subsection (a) and (b) by reason of clause
(iii) of subsection (a), then the fee paid under this subsection (c) shall
offset such amounts required to be paid by reason of such clause (iii) of
subsection (a).
 
    (d) The Company agrees that the agreements contained in Section 7.5(a) and
7.5(b) are an integral part of the transactions contemplated by this Agreement.
If the Company fails to promptly pay Parent any fee due under Section 7.5(a) or
7.5(b), the Company shall pay the costs and expenses (including legal fees and
expenses) in connection with any action, including the filing of any lawsuit or
other legal action, taken to collect payment, together with interest on the
amount of any unpaid fee at the publicly announced prime rate of Bankers Trust
Company from the date such fee was first due.

                                AMENDMENT NO. 1
                                       TO
                          AGREEMENT AND PLAN OF MERGER
    
 
   
    THIS AMENDMENT NO. 1 TO AGREEMENT AND PLAN OF MERGER (this "Amendment") is
entered into as of October 9, 1997, by and among U. S. OFFICE PRODUCTS COMPANY,
a Delaware corporation ("PARENT"), SANTA FE ACQUISITION CORP., a California
corporation and a direct, wholly-owned subsidiary of Parent ("SUB"), and MAIL
BOXES ETC., a California corporation (the "COMPANY"). This Amendment amends the
Agreement and Plan of Merger dated as of May 22, 1997 (the "Merger Agreement")
among Parent, Sub and the Company. Terms used herein that are not defined shall
have the meanings ascribed thereto in the Merger Agreement.
    
 
   
                                    RECITAL
    
 
   
    WHEREAS, on October 7, 1997 Parent announced a three-for-two stock split for
shares of Parent Common Stock, with a record date of October 23, 1997 (the
"SPLIT RECORD DATE") for the dividend effecting such stock split, which record
date will be prior to the Closing Date; and
    
 
   
    WHEREAS, Parent, Sub and the Company have determined that it is in their
respective best interests for the Merger Agreement to be amended in certain
respects.
    
 
   
    NOW, THEREFORE, in consideration of the premises and of the covenants and
agreements herein contained, the parties hereto, intending to be legally bound,
agree as follows:
    
 
   
    1. Section 2.1(c) of the Merger Agreement is amended in its entirety to read
as follows:
    
 
   
        "(c) CONVERSION OF COMMON STOCK. Each share of Company Common Stock
    issued and outstanding as of the Effective Time, other than shares to be
    cancelled in accordance with Section 2.1(b) or that are held by stockholders
    ("DISSENTING STOCKHOLDERS") duly exercising dissenters' rights pursuant to
    Chapter 13 of the CGCL and Section 2.3 hereof, shall be converted, subject
    to Section 2.2(d), into the right to receive one and one-half shares of
    Parent Common Stock (the "EXCHANGE RATIO"), subject to adjustment as
    provided for in this Section 2.1(c). The Exchange Ratio shall not be
    adjusted if the Share Value (as defined below) is equal to or greater than
    $15.33, but no greater than $19.33. If the Share Value is greater than
    $19.33, then the Exchange Ratio shall automatically be adjusted to equal 1.5
    times the quotient of (i) $19.33 divided by (ii) the Share Value. If the
    Share Value is less than $15.33, then, if the Company has notified Parent of
    its election to terminate this Agreement pursuant to Section 7.1(i) hereof,
    Parent shall have the option in its sole and absolute discretion, but not
    the obligation, to adjust the Exchange Ratio to be equal to 1.5 times the
    quotient of (iii) $15.33, divided by (iv) the Share Value, and the Company
    shall be obligated to accept such adjustment. If the Share Value is less
    than $15.33, and if the Company does not elect to terminate this Agreement
    pursuant to Section 7.1(i), the Exchange Ratio shall be unchanged."
    
 
   
    2. The paragraph immediately following Section 2.1(c) of the Merger
Agreement is amended in its entirety to read as follows:
    
 
   
    "For purposes hereof, the "SHARE VALUE" shall be an amount equal to the
    average closing price for the Parent Common Stock as reported on the
    Nasdaq National Market System for the twenty (20) consecutive trading
    days prior to the date two (2) business days prior to the Company
    Stockholders' Meeting (as defined in Section 5.1(d)), so long as the
    Closing Date occurs within five business days of the Company
    Stockholders' Meeting or, if the Closing Date is more than five business
    days after the Company Stockholders' Meeting, the Closing Date.
    Notwithstanding the foregoing, in the event any of such 20 consecutive
    trading days is before the first day on which Parent Common Stock trades
    ex-dividend (each a "PRE-SPLIT TRADING DAY"), for purposes of the
    calculation to be made pursuant to this paragraph the closing price for
    the Parent Common Stock for each Pre-Split Trading Day shall be
    multiplied by two-thirds."
    
 
                                       1
<PAGE>
   
    3. The following paragraph shall be added at the end of section 2.1 of the
Merger Agreement:
    
 
   
        "If after October 7, 1997 and prior to the Effective Time Parent shall
    declare a stock split (including a reverse split) of Parent Common Stock or
    a dividend payable in Parent Common Stock (in addition to or in lieu of the
    stock split described herein), or any other distribution of securities to
    holders of Parent Common Stock with respect to their Parent Common Stock, or
    if Parent does not effect the stock split announced on October 7, 1997, then
    the number of shares of Parent Common Stock to be issued upon conversion of
    a share of Company Common Stock pursuant to Section 2.1(c) shall be
    appropriately adjusted (pursuant to the appropriate adjustment of all
    relevant share amounts and all relevant dollar amounts) to reflect such
    stock split, dividend or other distribution of securities or to reflect the
    failure to effect the stock split announced on October 7, 1997, in each case
    to preserve the economic terms of the Merger."
    
 
   
    4. All references to "October 31, 1997" in Sections 7.1 (b), (c) and (e) of
the Merger Agreement are amended to read "November 30, 1997."
    
 
   
    5. Section 7.1(i) of the Merger Agreement is amended in its entirety to read
as follows:
    
 
   
        "(i) by the Company, if the Share Value would be less than $15.33 per
    share unless Parent, within three days after receipt of written notice by
    the Company of its intention to so terminate, may have elected to adjust the
    Exchange Ratio pursuant to the fourth sentence of Section 2.1(c) hereof."
    
 
   
    6. This Amendment shall be governed by, and construed and enforced in
accordance with, the laws of the State of California, regardless of the laws
that might otherwise govern under applicable principles of conflict of laws
thereof.
    
 
   
    7. As amended hereby, the Merger Agreement is ratified and confirmed in all
respects.
    
 
   
    IN WITNESS WHEREOF, Parent, Sub and the Company have caused this Agreement
to be signed by their respective officers thereunto duly authorized, all as of
the date first written above.

May 22, 1997
 
Board of Directors
Mail Boxes Etc.
6060 Cornerstone Court West
San Diego, CA 92121-3795
 
Members of the Board:
 
We understand that Mail Boxes Etc. (the "Company"), U.S. Office Products Company
(the "Acquiror") and Santa Fe Acquisition Corp., a wholly owned subsidiary of
the Acquiror (the "Acquisition Sub"), propose to enter into an Agreement and
Plan of Merger dated May 22, 1997 (the "Merger Agreement") pursuant to which
Acquisition Sub will be merged with and into the Company in a transaction (the
"Merger") in which each issue and outstanding share of common stock of the
Company, no par value per share (the "Company Common Stock"), will be converted
into the right to receive 1.0 (the "Exchange Ratio") share of common stock of
the Acquiror, $0.001 par value per share (the "Acquiror Common Stock"), provided
that (i) if the average closing price (as reported on the Nasdaq National
Market) for the Acquiror Common Stock for the twenty (20) consecutive trading
days prior to the date two (2) business days prior to the Company Stockholders'
Meeting (as defined in the Merger Agreement) ("Share Value") is greater than
$29.00, each outstanding share of Company Common Stock will be converted into
the right to receive a fraction of a share of Acquiror Common Stock determined
by dividing $29.00 by the Share Value, and (ii) if the Share Value is less than
$23.00, the parties may mutually agree that the Exchange Ratio will remain 1.0,
or the Exchange Ratio may be adjusted, if requested by the Company and agreed to
by the Acquiror, so that each share of Company Common Stock will be converted
into the right to receive that number of shares of Acquiror Common Stock
determined by dividing $23.00 by the Share Value. In the absence of any such
agreement contemplated by clause (ii) above, the Company shall have the right to
terminate the Merger Agreement.
 
You have asked us whether, in our opinion, the Exchange Ratio to be received by
the holders of Company Common Stock in the Merger is fair to such stockholders
from a financial point of view.
 
In connection with this opinion, we have reviewed the Merger Agreement and
certain related documents and held discussions with certain senior officers,
directors and other representatives and advisors of the Company and certain
senior officers and other representatives of the Acquiror concerning the
businesses, operations and prospects of the Company and the Acquiror. We
examined certain publicly available business and financial information relating
to the Company and the Acquiror as well as certain financial data and other data
for the Company and certain financial information and other data related to the
Acquiror which were provided to or otherwise discussed with us by the respective
management of the Company and the Acquiror. We reviewed the financial terms of
the Merger as set forth in the Merger Agreement in relation to: (i) current and
historical market prices and trading volumes of Company Common Stock and
Acquiror Common Stock: (ii) the respective companies' financial and other
operating data; and (iii) the capitalization and financial condition of the
Company and the Acquiror. We also considered, to the extent publicly available,
the financial terms of certain other similar transactions recently effected
which we considered relevant in evaluating the Merger and analyzed certain
financial, stock market and other publicly available information relating to the
businesses of other companies whose operations we considered relevant in
evaluating those of the Company and the Acquiror. In connection with our
engagement, we identified, approached and held discussions with certain third
parties to solicit indications of interest in a possible acquisition of the
Company.
 
In rendering our opinion, we have assumed and relied upon the accuracy and
completeness of the financial and other information reviewed by us and we have
not made or obtained or assumed any responsibility for independent verification
of such information. In addition, we have not made an independent evaluation or
appraisal of the assets and liabilities of the Company or the Acquiror or any of
their respective subsidiaries. With respect to the financial data of the
Company, we have assumed that it has been reasonably prepared on bases
reflecting the best currently available estimates and judgments of the
<PAGE>
management of the Company as to the future financial performance of the Company.
We have assumed that the Merger will be consummated in accordance with the terms
of the Merger Agreement including among other things, that the Merger will be
accounted for as a pooling of interests under generally accepted accounting
principles and as a tax-free reorganization for federal income tax purposes. We
are not expressing any opinion in the event that the Share Value is less than
$23.00. We are also not expressing any opinion as to what the value of the
Acquiror Common Stock actually will be when issued to the Company stockholders
pursuant to the Merger or the price at which the Acquiror Common Stock will
trade subsequent to the Merger.
 
ABN AMRO Chicago Corporation ("AACC"), as part of its investment banking
business, is continually engaged in the valuation of businesses in connection
with mergers and acquisitions, as well as initial and secondary offerings of
securities and valuations for other purposes. We have acted as financial advisor
to the Board of Directors of the Company in connection with this transaction and
will receive a fee for our services, including rendering this opinion, a
significant portion of which is contingent upon the consummation of the Merger.
In the ordinary course of our business, AACC and its affiliates may actively
trade securities of both the Company and Acquiror for their own account and for
the accounts of customers and, accordingly, may at any time hold a long or short
position in such securities.
 
It is understood that this letter is solely for the benefit and use of the Board
of Directors of the Company in its consideration of the Merger and may not be
relied upon by any other person, used for any other purpose or reproduced,
disseminated, quoted or referred to at any time, in any manner or for any
purpose without our prior written consent, except that this letter may be used
as part of any proxy statement/ prospectus relating to the Merger. This letter
does not address the Company's underlying business decision to enter into the
Merger or constitute a recommendation to any shareholder as to how such
shareholder should vote with respect to the proposed Merger. Finally, our
opinion is necessarily based on economic, monetary, market and other conditions
as in effect on, and the information made available to us, as of the date
hereof, and we assume no responsibility to update or revise our opinion based
upon circumstances or events occurring after the date hereof.
 
Based upon and subject to the foregoing, we are of the opinion that, as of the
date hereof, the Exchange Ratio is fair from a financial point of view to the
shareholders of the Company.
 
                                          Very truly yours,
                                          ABN AMRO CHICAGO CORPORATION

SECTION1300. REORGANIZATION OR SHORT-FORM MERGER; DISSENTING SHARES; CORPORATE
  PURCHASE AT FAIR MARKET VALUE; DEFINITIONS.
 
    (a) If the approval of the outstanding shares (Section 152) of a corporation
is required for a reorganization under subdivisions (a) and (b) or subdivision
(e) or (f) of Section 1201, each shareholder of the corporation entitled to vote
on the transaction and each shareholder of a subsidiary corporation in a
short-form merger may, by complying with this chapter, require the corporation
in which the shareholder holds shares to purchase for cash at their fair market
value the shares owned by the shareholder which are dissenting shares as defined
in subdivision (b). The fair market value shall be determined as of the day
before the first announcement of the terms of the proposed reorganization or
short-form merger, excluding any appreciation or depreciation in consequence of
the proposed action, but adjusted for any stock split, reverse stock split, or
share dividend which becomes effective thereafter.
 
    (b) As used in this chapter, "dissenting shares" means shares which come
within all of the following descriptions:

Commissioner of Corporations under subdivision (o) of Section 25100 or (B)

provision does not apply to any class of shares described in *** subparagraph
(A) or (B) if demands for payment are filed with respect to 5 percent or more of
the outstanding shares of that class.
 
    (2) Which were outstanding on the date for the determination of shareholders
entitled to vote on the reorganization and (A) were not voted in favor of the

against the reorganization, or which were held of record on the effective date
of a short-form merger; provided, however, that *** subparagraph (A) rather than
*** subparagraph (B) of this paragraph applies in any case where the approval
required by Section 1201 is sought by written consent rather than at a meeting.
 
    (3) Which the dissenting shareholder has demanded that the corporation
purchase at their fair market value, in accordance with Section 1301.

SECTION 1301. NOTICE TO HOLDERS OF DISSENTING SHARES IN REORGANIZATIONS; DEMAND
  FOR PURCHASE; TIME; CONTENTS.
 
    (a) If, in the case of a reorganization, any shareholders of a corporation
have a right under Section 1300, subject to compliance with paragraphs (3) and
(4) of subdivision (b) thereof, to require the corporation to purchase their
shares for cash, such corporation shall mail to each such shareholder a notice
of the approval of the reorganization by its outstanding shares (Section 152)
within 10 days after the date of such approval, accompanied by a copy of
Sections 1300, 1302, 1303, 1304 and this section, a statement of the price
determined by the corporation to represent the fair market value of the
dissenting shares, and a brief description of the procedure to be followed if
the shareholder desires to exercise the shareholder's right under such sections.
The statement of price constitutes an offer by the corporation to purchase at
the price stated any dissenting shares as defined in subdivision (b) of Section
1300, unless they lose their status as dissenting shares under Section 1309.
 
    (b) Any shareholder who has a right to require the corporation to purchase
the shareholder's shares for cash under Section 1300, subject to compliance with
paragraphs (3) and (4) of subdivision (b) thereof, and who desires the
corporation to purchase such shares shall make written demand upon the
corporation for the purchase of such shares and payment to the shareholder in
cash of their fair market value. The demand is not effective for any purpose
unless it is received by the corporation or any transfer agent thereof (1) in
the case of shares described in clause (i) or (ii) of paragraph (1) of
subdivision (b) of Section 1300 (without regard to the provisos in that
paragraph), not later than the date of the shareholders' meeting to vote upon
the reorganization, or (2) in any other case within 30 days after the date on
which the notice of the approval by the outstanding shares pursuant to
subdivision (a) or the notice pursuant to subdivision (i) of Section 1110 was
mailed to the shareholder.
 
                                       2
<PAGE>
    (c) The demand shall state the number and class of the shares held of record
by the shareholder which the shareholder demands that the corporation purchase
and shall contain a statement of what such shareholder claims to be the fair
market value of those shares as of the day before the announcement of the
proposed reorganization or short-form merger. The statement of fair market value
constitutes an offer by the shareholder to sell the shares at such price. (ADDED

its principal office or at the office of any transfer agent thereof, (a) if the
shares are certificated securities, the shareholder's certificates representing
any shares which the shareholder demands that the corporation purchase, to be
stamped or endorsed with a statement that the shares are dissenting shares or to
be exchanged for certificates of appropriate denomination so stamped or endorsed

subsequent transfers of the dissenting shares on the books of the corporation,
the new certificates, initial transaction statement, and other written
statements issued therefor shall bear a like statement, together with the name
of the original dissenting holder of the shares. (ADDED BY STATS. 1975, C. 682,

SECTION 1303. PAYMENT OF AGREED PRICE WITH INTEREST; AGREEMENT FIXING FAIR
  MARKET VALUE; FILING; TIME OF PAYMENT.
 
    (a) If the corporation and the shareholder agree that the shares are
dissenting shares and agree upon the price of the shares, the dissenting
shareholder is entitled to the agreed price with interest thereon at the legal
rate on judgments from the date of the agreement. Any agreements fixing the fair
market value of any dissenting shares as between the corporation and the holders
thereof shall be filed with the secretary of the corporation.
 
    (b) Subject to the provisions of Section 1306, payment of the fair market
value of dissenting shares shall be made within 30 days after the amount thereof
has been agreed or within 30 days after any statutory or contractual conditions
to the reorganization are satisfied, whichever is later, and in the case of
certificated securities, subject to surrender of the certificates therefor,
unless provided otherwise by agreement. (ADDED BY STATS. 1975, C. 682, SECTION

  MARKET VALUE; LIMITATION; JOINDER; CONSOLIDATION; DETERMINATION OF ISSUES;
  APPOINTMENT OF APPRAISERS.
 
    (a) If the corporation denies that the shares are dissenting shares, or the
corporation and the shareholders fail to agree upon the fair market value of the
shares then the shareholder demanding purchase of such shares as dissenting
shares or any interested corporation, within six months after the date on which
notice of the approval by the outstanding shares (Section 152) or notice
pursuant to subdivision (i) of Section 1110 was mailed to the shareholder, but
not thereafter, may file a complaint in the superior court of the proper county
praying the court to determine whether the shares are dissenting shares or the

fair market value of the dissenting shares or both or may intervene in any
action pending on such a complaint.
 
    (b) Two or more dissenting shareholders may join as plaintiffs or be joined
as defendants in any such action and two or more such actions may be
consolidated.
 
    (c) On the trial of the action, the court shall determine the issues. If the
status of the shares as dissenting shares is in issue, the court shall first
determine that issue. If the fair market value of the dissenting shares is in
issue, the court shall determine, or shall appoint one or more impartial
appraisers to determine the fair market value of the shares. (ADDED BY STATS.
1975, C. 682, SECTION 7, EFF. JAN. 1, 1977).

  JUDGMENT; PAYMENT; APPEAL; COSTS.
 
    (a) If the court appoints an appraiser or appraisers, they shall proceed
forthwith to determine the fair market value per share. Within the time fixed by

court shall determine the fair market value of the dissenting shares.
 
    (c) Subject to the provisions of Section 1306, judgment shall be rendered
against the corporation for payment of an amount equal to the fair market value
of each dissenting share multiplied by the number of dissenting shares which any
dissenting shareholder who is a party, or who has intervened, is entitled to
require the corporation to purchase, with interest thereon at the legal rate
from the date on which judgment was entered.
 
    (d) Any such judgment shall be payable forthwith with respect to
uncertificated securities and, with respect to certificated securities, only
upon the endorsement and delivery to the corporation of the certificates for the
shares described in the judgment. Any party may appeal from the judgment.
 
    (c) The costs of the action, including reasonable compensation to the
appraisers to be fixed by the court, shall be assessed or apportioned as the
court considers equitable, but, if the appraisal exceeds the price offered by
the corporation, the corporation shall pay the costs (including in the
discretion of the court attorneys' fees, fees of expert witnesses and interests
at the legal rate on judgments from the date of compliance with Sections 1300,
1301 and 1302 if the value awarded by the court for the shares is more than 125
percent of the price offered by the corporation under subdivision (a) of Section
1301). (ADDED BY STATS. 1975, C. 682, SECTION 7, EFF. JAN. 1. 1977. AMENDED BY

    Except as expressly limited in this chapter, holders of dissenting shares
continue to have all the rights and privileges incident to their shares, until

thereof cease to be dissenting shareholders and cease to be entitled to require

shareholder who has initiated proceedings in good faith under this chapter all
necessary expenses incurred in such proceedings and reasonable attorneys' fees.
 
    (b) The shares are transferred prior to their submission for endorsement in
accordance with Section 1302 or are surrendered for conversion into shares of
another class in accordance with the articles.
 
    (c) The dissenting shareholder and the corporation do not agree upon the

the approval by the outstanding shares or notice pursuant to subdivision (i) of

SECTION 1311. EXEMPT SHARES
 
    This chapter, except Section 1312, does not apply to classes of shares whose
terms and provisions specifically set forth the amount to be paid in respect of
such shares in the event of a reorganization or merger. (Added by Stats. 1975,
c. 682, Section 7, eff. Jan. 1, 1977. Amended by Stats. 1988, c. 919, Section

SECTION 1312. RIGHT OF DISSENTING SHAREHOLDER TO ATTACK, SET ASIDE OR RESCIND
  MERGER OR REORGANIZATION; RESTRAINING ORDER OR INJUNCTION; CONDITIONS
 
    (a) No shareholder of a corporation who has a right under this chapter to
demand payment of cash for the shares held by the shareholder shall have any
right at law or in equity to attack the validity of the reorganization or
short-form merger, or to have the reorganization or short-form merger set aside
or rescinded, except in an action to test whether the number of shares required
to authorize or approve the reorganization have been legally voted in favor
thereof; but any holder of shares of a class whose terms and provisions
specifically set forth the amount to be paid in respect to them in the event of
a reorganization or short-form merger is entitled to payment in accordance with
those terms and provisions or, if the principal terms of the reorganization are
approved pursuant to subdivision (b) of Section 1202, is entitled to payment in
accordance with the terms and provisions of the approved reorganization.
 
    (b) If one of the parties to a reorganization or short-form merger is
directly or indirectly controlled by, or under common control with, another
party to the reorganization or short-form merger, subdivision (a) shall not
apply to any shareholder of such party who has not demanded payment of cash for
such shareholder's shares pursuant to this chapter; but if the shareholder
institutes any action to attack the validity of the reorganization or short-form
merger or to have the reorganization or short-form merger set aside or
rescinded, the shareholder shall not thereafter have any right to demand payment
of cash for the shareholder's shares pursuant to this chapter. The court in any
action attacking the validity of the reorganization or short-form merger or to
have the reorganization or short-form merger set aside or rescinded shall not
restrain or enjoin the consummation of the transaction except upon 10 days'
prior notice to the corporation and upon a determination by the court that
clearly no other remedy will adequately protect the complaining shareholder or
the class of shareholders of which such shareholder is a member.
 
    (c) If one of the parties to a reorganization or short-form merger is
directly or indirectly controlled by, or under common control with, another
party to the reorganization or short-form merger, in any action to attack the
validity of the reorganization or short-form merger or to have the
reorganization or short-form merger set aside or rescinded, (1) a party to a
reorganization or short-form merger which controls another party to the
reorganization or short-form merger shall have the burden of proving that the
transaction is just and reasonable as to the shareholders of the controlled
party, and (2) a person who controls two or more parties to a reorganization
shall have the burden of proving that the transaction is just and reasonable as
to the shareholders of any party so controlled. (ADDED BY STATS. 1975, C. 682,

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
    USOP's Amended and Restated By-laws provide that USOP shall, to the fullest
extent permitted by Section 145 of the General Corporation Law of the State of
Delaware, as amended from time to time, indemnify all persons whom it may
indemnify pursuant thereto.
 
    Section 145 of the General Corporation Law of the State of Delaware permits
a corporation, under specified circumstances, to indemnify its directors,
officers, employees or agents against expenses (including attorney's fees),
judgments, fines and amounts paid in settlements actually and reasonably
incurred by them in connection with any action, suit or proceeding brought by
third parties by reason of the fact that they were or are directors, officers,
employees or agents of the corporation, if such directors, officers, employees
or agents acted in good faith and in a manner they reasonably believed to be in
or not opposed to the best interests of the corporation and, with respect to any
criminal action or proceeding, had no reason to believe their conduct was
unlawful. In a derivative action, i.e., one by or in the right of the
corporation, indemnification may be made only for expenses actually and
reasonably incurred by directors, officers, employees or agents in connection
with the defense or settlement of an action or suit, and only with respect to a
matter as to which they shall have acted in good faith and in a manner they
reasonably believed to be in or not opposed to the best interests of the
corporation, except that no indemnification shall be made if such person shall
have been adjudged liable to the corporation, unless and only to the extent that
the court in which the action or suit was brought shall determine upon
application that the defendant directors, officers, employees or agents are
fairly and reasonably entitled to indemnity for such expenses despite such
adjudication of liability.
 
    Article Eight of USOP's Amended and Restated Certificate of Incorporation
provides that USOP directors will not be personally liable to USOP or its
stockholders for monetary damages resulting from breaches of their fiduciary
duty as directors except (a) for any breach of the duty of loyalty to USOP or
its stockholders, (b) for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (c) under Section 174 of
the General Corporation Law of the State of Delaware, which makes directors
liable for unlawful dividends or unlawful stock repurchases or redemptions or
(d) for transactions from which directors derive improper personal benefit.

ITEM 22. UNDERTAKINGS
 
    Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the provisions described in Item 14, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.
 
    The undersigned Registrant hereby undertakes:
 
    (1) To file, during any period in which any offers or sales are being made,
a post-effective amendment to the registration statement:
 
    (i) To include any prospectus required by Section 10(a)(3) of the Securities
Act of 1933;
 
    (ii) To reflect in the prospectus any facts or events arising after the
effective date of the registration statement (or the most recent post-effective
amendment thereof) which, individually or in aggregate, represent a fundamental
change in the information set forth in the registration statement.
Notwithstanding the foregoing, any increase or decrease in volume of securities
offered (if the total dollar value of securities offered would not exceed that
which was registered) and any deviation from the low or high and of the
estimated maximum offering range may be reflected in the form of prospectus
filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the
changes in volume and price represent no more than 20
 
                                      II-2
<PAGE>
percent change in the maximum aggregate offering price set forth in the
"Calculation of Registration Fee" table in the effective registration statement;
 
    (iii) To include any material information with respect to the plan of
distribution not previously disclosed in the registration statement or any other
material change to such information in the registration statement.
 
    (2) That for the purpose of determining any liability under the Act each
such post-effective amendment may be deemed to be a new registration statement
relating to the securities being offered therein and the offering of such
securities at the time may be deemed to be the initial bona fide offering
thereof.
 
    (3) To remove from registration by means of a post-effective amendment any
of the securities which are being registered which remain unsold at the
termination of the offering.
 
    (4) That, for purposes of determining any liability under the Securities Act
of 1933, each filing of the registrant's annual report pursuant to Section 13(a)
or Section 15(d) of the Securities Exchange Act of 1934 that is incorporated by
reference in the registration statement shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.
 
    (5) To deliver or cause to be delivered with the Prospectus, to each person
to whom the Prospectus is sent or given, the latest annual report to security
holders that is incorporated by reference in the Prospectus and furnished
pursuant to and meeting the requirements of Rule 14a-3 or Rule 14c-3 under the
Securities Exchange Act of 1934; and where interim financial information
required to be presented by Article 3 of Regulation S-X are not set forth in the
Prospectus, to deliver, or caused to be delivered to each person to whom the
Prospectus is sent or given, the latest quarterly report that is specifically
incorporated by reference in the Prospectus to provide such interim financial
information.
 
    (6) As follows: that prior to any public reoffering of the securities
registered hereunder through use of a prospectus which is a part of this
registration statement, by any person or party who is deemed to be an
underwriter within the meaning of Rule 145(c), the issuer undertakes that such
reoffering prospectus will contain the information called for by the applicable
registration form with respect to reoffering by persons who may be deemed
underwriters, in addition to the information called for by the other items of
the applicable form.
 
    (7) That every prospectus (i) that is filed pursuant to paragraph (1)
immediately preceding or (ii) that purports to meet the requirements of Section
10(a)(3) of the Act and is used in connection with an offering of securities
subject to Rule 415, will be filed as part of an amendment to the registration
statement and will not be used until such amendment is effective, and that, for
purposes of determining any liability under the Securities Act of 1933, each
such post-effective amendment shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
 
    (8) To respond to requests for information that is incorporated by reference
into the Prospectus pursuant to Items 4, 10(b), 11, or 13 of this Form, within
one (1) business day of receipt of such request, and to sent the incorporated
documents by first class mail or other equally prompt means. This includes
information contained in documents filed subsequent to the effective date of the
registration statement through the date of responding to the request.
 
    (9) To supply by means of a post-effective amendment, Rule 424(c) supplement
or information incorporated by reference, all information concerning a material
transaction, and the company being acquired involved there, that was not the
subject of and included in the registration statement when it became effective.

Re: Issuance of Shares Pursuant to Registration Statement on Form S-4

Ladies and Gentlemen:

   

We have acted as counsel to U.S. Office Products Company, a Delaware 
corporation (the "Company"), in connection with the preparation and filing 
with the Securities and Exchange Commission under the Securities Act of 1933, 
as amended (the "Act"), of a Registration Statement on Form S-4 (the 
"Registration Statement") relating to the offering of up to 19,530,457 shares 
of common stock, $.001 par value per share (the "Shares"), which Shares may 
be issued in connection with the merger of a wholly owned subsidiary of the 
Company with and into Mail Boxes Etc., a California corporation ("MBE"), 
pursuant to the terms and conditions of the Agreement and Plan of Merger (the 
"Merger Agreement") dated as of May 22, 1997 and as amended on October 9, 
1997 among the Company, Santa Fe Acquisition Corp. and MBE.  Of the 
19,530,457 Shares, 2,430,004 shares relate to outstanding options of MBE 
that, upon consummation of the merger,  will be converted into the right to 
purchase Shares of USOP.

    

We understand that the issuance of the Shares pursuant to the Merger 
Agreement is contingent upon, among other things, the requisite approval of 
the Merger by the shareholders of MBE, and the filing of Articles of Merger 
with the Secretary of State of the State of Delaware and the Secretary of 
State of the State of California. In rendering the opinion set forth below, 
we have examined originals, or copies certified or otherwise identified to our 
satisfaction, of such documents, records, certificates and other instruments 
of the Company as in our judgment are necessary or appropriate for purposes 
of this opinion. In our examination, we have assumed the genuineness of all 
signatures, the authenticity of all documents submitted to us as originals, 
and the conformity with the originals of all documents submitted to us as 
copies thereof.

Our opinion set forth below is limited to the Delaware General Corporation 
Law.

   

Based upon the foregoing, we are of the opinion that, when and to the extent 
that (i) the Registration Statement has become effective under the Act, (ii) 
the three-for-two stock split in the form of a dividend announced by the 
Company on October 7, 1997 is paid prior to the issuance of the Shares, (iii) 
the shareholders of MBE have approved the Merger, (iv) the appropriate 
filings have been made concerning the Merger with the Secretary of State of 
the State of Delaware and the Secretary of State of the State of 
California, and (v) the Shares are issued as described in the Registration 
Statement and in accordance with the terms and conditions of the Merger 
Agreement, including provisions relating to outstanding options of MBE, the 
Shares will be validly issued, fully paid and nonassessable.

We hereby consent to the use of this opinion as an exhibit to the Registration 
Statement and to the use of our name under the caption "Legal Matters" in the 
Registration Statement. In giving such consent, we do not hereby admit that 
we are acting within the category of persons whose consent is required under 
Section 7 of the Act and the rules and regulations of the Commission 
thereunder.

Very truly yours,


/s/ Morgan, Lewis and Bockius LLP
