ITEM 8. FAIRNESS OF THE TRANSACTION.

incorporated herein by reference.


   Each of the #6 GST Exempt Trust and the #7 GST Exempt Trust believes that 
the Merger is fair to the stockholders of the Company. Neither the #6 GST 
Exempt Trust nor the #7 GST Exempt Trust has undertaken any formal evaluation 
of the fairness of the Merger to the stockholders of the Company and did not 
find it practicable to quantify or otherwise attach relative weights to the 
various factors considered by them. However, in arriving at their belief that 
the Merger is fair to the stockholders of the Company, each of the #6 GST 
Exempt Trust and the #7 GST Exempt Trust considered the fact that (i) the BRS 
offer reflected a multiple of the Company's estimated 1997 EBITDA of 8.0x 
(and estimated 1998 EBITDA of 7.4x), which was higher than was 
offered in the 1995 auction process and compared favorably to selected latest 
12 months EBITDA multiples ranging from 6.4x to 7.9x in recent, comparable 
transactions, (ii) the Merger Consideration represented a substantial premium 
over the market price, both current and historical, of MEDIQ Stock, (iii) the 
Company had conducted, with the assistance of its professional advisors, an 
extensive auction, (iv) the Board had received the written opinion of its 
independent financial advisor (included herein as Exhibit (b)(2)) and (v) the 
Board had appointed Mr. Levitan to serve as a Special Committee to evaluate 
the fairness of the proposed transaction with BRS. 

    

   (c) The information set forth in "THE SPECIAL MEETING -- Record Date; 
Stock Entitled to Vote; Quorom" of the Proxy Statement/Prospectus is

Dear Fellow Stockholders:
 
   
    You are cordially invited to attend a Special Meeting (including any
adjournments or postponements thereof, the "Special Meeting") of the
stockholders of MEDIQ Incorporated (the "Company") to vote on the proposed
merger (the "Merger") of the Company with MQ Acquisition Corporation, a Delaware
corporation ("MQ") that has been organized by Bruckmann, Rosser, Sherrill & Co.,
L.P. Details of the Merger are discussed in the enclosed Proxy
Statement/Prospectus (the "Proxy Statement/Prospectus"), the forepart of which
includes a summary of the terms of the Merger and certain other information
relating to the proposed transactions.
    
 
    At the special meeting, you will be asked to approve and adopt the Agreement
and Plan of Merger, dated as of January 14, 1998 (the "Merger Agreement"), and
the transactions contemplated thereby. A copy of the Merger Agreement is
attached as Annex A to the enclosed Proxy Statement/Prospectus. Please carefully
read the accompanying Proxy Statement/Prospectus, which contains a detailed
description of the Merger and the Merger Agreement.
 
   
    On January 14, 1998, a Special Committee of the Board of Directors (the
"Special Committee") and the Board of Directors of the Company, by unanimous
vote (i) determined that the Merger, the Merger Agreement and the transactions
contemplated thereby are fair to and in the best interests of the holders of the
common stock, par value $1.00 per share, of the Company (the "MEDIQ Common
Stock"), (ii) determined that the Merger, the Merger Agreement and the
transactions contemplated thereby are fair to and in the best interests of the
holders of the Series A preferred stock, par value $.50 per share, of the
Company (the "MEDIQ Preferred Stock"), and (iii) recommended that holders of
MEDIQ Common Stock and holders of MEDIQ Preferred Stock each approve the Merger,
the Merger Agreement and the transactions contemplated thereby.
    
 
   
    The Merger requires the approval at the Special Meeting of (i) the holders
of a majority of the outstanding voting power of the MEDIQ Common Stock and the
MEDIQ Preferred Stock, voting together as a single class and (ii) the holders of
a majority of the outstanding shares of MEDIQ Preferred Stock. Pursuant to
stockholder agreements between MQ and certain stockholders of the Company,
holders of 4,701,464 shares of Common Stock and 4,730,006 shares of MEDIQ
Preferred Stock, representing approximately 24% of the outstanding MEDIQ Common
Stock (without giving effect to the conversion of any shares of MEDIQ Preferred
Stock into shares of MEDIQ Common Stock), approximately 75% of the outstanding
MEDIQ Preferred Stock and approximately 63% of the total combined voting power
of the MEDIQ Common Stock and the MEDIQ Preferred Stock voting together as a
single class (in each case without giving effect to the exercise of any
outstanding options to acquire MEDIQ Stock), have agreed to vote their shares in
favor of the Merger, the Merger Agreement and the other actions contemplated
thereby, subject to the terms and conditions thereof. The affirmative vote of
the shares of MEDIQ Stock subject to the stockholder agreements will be
sufficient to approve the Merger and the Merger Agreement.

Incorporated, a Delaware corporation (the "Company"), will be held at the
Company's corporate headquarters located at One MEDIQ Plaza, Pennsauken, New

        1. To consider and vote upon a proposal to approve and adopt the
    Agreement and Plan of Merger, dated as of January 14, 1998 (the "Merger
    Agreement"), between the Company and MQ Acquisition Corporation, a Delaware
    corporation ("MQ") organized by Bruckmann, Rosser, Sherrill & Co., L.P., and
    the transactions contemplated thereby, including the merger of MQ with and

    share of common stock, par value $1.00 per share, of the Company (the "MEDIQ
    Common Stock") and each share of Series A preferred stock, par value $.50
    per share, of the Company (the "MEDIQ Preferred Stock" and, collectively
    with the MEDIQ Common Stock, the "MEDIQ Shares" or the "MEDIQ Stock") issued
    and outstanding immediately prior to the effective time of the Merger (the
    "Effective Time") will be converted into the right to receive (i) $13.75 in
    cash, without interest, and (ii) 0.075 of a share of the Surviving
    Corporation's Series A 13% Cumulative Compounding Preferred Stock, par value

    dissenting shares. Each MEDIQ Share that is issued and outstanding
    immediately prior to the Effective Time and owned by MQ or the Company or
    any direct or indirect subsidiary of MQ or the Company will be canceled and
    no payments or any consideration will be made with respect thereto. See "THE
    MERGER--Merger Consideration" in the accompanying Proxy

of a majority of the outstanding voting power of the MEDIQ Common Stock and the

Stock into shares of MEDIQ Common Stock), approximately 75% of the outstanding
MEDIQ Preferred Stock and approximately 63% of the total combined voting power
of the MEDIQ Common Stock and the MEDIQ Preferred Stock voting together as a
single class (in each case without giving effect to the exercise of any
outstanding options to acquire MEDIQ Stock), have agreed to vote their shares in
favor of the Merger, the Merger Agreement and the other actions contemplated
thereby, subject to the terms and conditions thereof. The affirmative

                               MEDIQ INCORPORATED
                                ONE MEDIQ PLAZA
                       PENNSAUKEN, NEW JERSEY 08110-1460
                           PROXY STATEMENT/PROSPECTUS
                            ------------------------
 
    This Proxy Statement/Prospectus (the "Proxy Statement/Prospectus") is being
furnished to stockholders of MEDIQ Incorporated, a Delaware corporation ("MEDIQ"
or the "Company"), in connection with the solicitation of proxies by the Board
of Directors of the Company for use at the Special Meeting of stockholders of
the Company, including any adjournments or postponements thereof, scheduled to
be held on           , 1998 at 9:00 a.m., at the Company's corporate
headquarters located at One MEDIQ Plaza, Pennsauken, NJ 08110-1460 (the "Special
Meeting"). This Proxy Statement/Prospectus relates to the proposed merger (the
"Merger") of MQ Acquisition Corporation, a Delaware corporation ("MQ") that has
been organized by Bruckmann, Rosser, Sherrill & Co., L.P. ("BRS"), with and into
the Company with the Company as the surviving corporation (the "Surviving
Corporation") pursuant to the Agreement and Plan of Merger, dated as of January
14, 1998 (the "Merger Agreement"), between MQ and the Company, and the
transactions contemplated thereby.
 
   
    Pursuant to the Merger, each share of common stock, par value $1.00 per
share, of the Company (the "MEDIQ Common Stock") and each share of Series A
preferred stock, par value $.50 per share, of the Company (the "MEDIQ Preferred
Stock" and, collectively with the MEDIQ Common Stock, the "MEDIQ Shares" or the
"MEDIQ Stock") issued and outstanding immediately prior to the effective time of
the Merger (the "Effective Time") will be converted into the right to receive
(i) $13.75 in cash, without interest, and (ii) 0.075 of a share of the Surviving
Corporation's Series A 13% Cumulative Compounding Preferred Stock, par value
$.01 per share with a liquidation preference of $10.00 per share (the "Series A
Preferred Stock") (such cash and Series A Preferred Stock, the "Merger
Consideration"), except for MEDIQ Shares owned directly or indirectly by MQ or
the Company, Rolled Shares (as defined herein), and Dissenting Shares (as
defined herein). Each MEDIQ Share that is issued and outstanding immediately
prior to the Effective Time and owned by MQ or the Company or any direct or
indirect subsidiary of MQ or the Company, will be canceled and no payments or
any consideration will be made with respect thereto. See "THE MERGER--Merger
Consideration." As a consequence of the Merger, it is currently expected that at
the Effective Time BRS, together with other co-investors selected by BRS, will
hold approximately 829,219 shares of common stock, par value $.01 per share, of
the Surviving Corporation (the "Surviving Corporation Common Stock"),
representing approximately 82.9% of the outstanding shares of the Surviving
Corporation Common Stock, and approximately 5,624,565 shares of Series A
Preferred Stock, representing approximately 71.8% of the outstanding shares of
Series A Preferred Stock, and a majority of the outstanding shares of each other
class of capital stock of the Company. A copy of the Merger Agreement is
attached as Annex A to this Proxy Statement/Prospectus.
    
 
    This Proxy Statement/Prospectus also constitutes a prospectus of the Company
with respect to the shares of Series A Preferred Stock of the Surviving
Corporation to be issued in the Merger.
 
    The Merger requires the approval at the Special Meeting of (i) the holders
of a majority of the outstanding voting power of the MEDIQ Common Stock and the
MEDIQ Preferred Stock, voting together as a single class, and (ii) the holders
of a majority of the shares of outstanding MEDIQ Preferred Stock. Pursuant to
stockholder agreements between MQ and certain stockholders of the Company,
holders of 4,701,464 shares of MEDIQ Common Stock and 4,730,006 shares of MEDIQ
Preferred Stock, representing approximately 24% of the outstanding MEDIQ Common
Stock (without giving effect to the conversion of any shares of MEDIQ Preferred
Stock into shares of MEDIQ Common Stock), 75% of the outstanding MEDIQ Preferred
Stock and approximately 63% of the total combined voting power of the MEDIQ
Common Stock and the MEDIQ Preferred Stock voting together as a single class (in
each case excluding treasury shares and without giving effect to the exercise of
any outstanding options to acquire MEDIQ Stock), have agreed to vote their
shares in favor of the Merger, the Merger Agreement and the other actions
contemplated thereby, subject to the terms and conditions thereof. See "THE
STOCKHOLDER AGREEMENTS." The affirmative vote of the shares of MEDIQ Stock
subject to the stockholders agreements will be sufficient to approve the Merger
and the Merger Agreement. Holders of MEDIQ Common Stock and MEDIQ Preferred
Stock who do not vote in favor of the Merger and who comply with the applicable
provisions of the Delaware General Corporation Law (the "DGCL") will be entitled
to dissenters' rights of appraisal in connection with the Merger as described
herein. See "DISSENTING STOCKHOLDERS' RIGHTS."
 
    A Special Committee of the Board of Directors (the "Special Committee") and
the Board of Directors (the "Board") of the Company, by unanimous vote of those
directors present (who constituted all of the directors then in office) have (i)
determined that the Merger, the Merger Agreement and the transactions
contemplated thereby are fair to and in the best interests of the holders of
MEDIQ Common Stock, (ii) determined that the Merger, the Merger Agreement and
the transactions contemplated thereby are fair to and in the best interests of
the holders of MEDIQ Preferred Stock, and (iii) recommended that holders of
MEDIQ Common Stock and holders of MEDIQ Preferred Stock each approve the Merger,
the Merger Agreement and the transactions contemplated thereby.
 
   
    MEDIQ Common Stock is listed for trading on the American Stock Exchange (the
"AMEX") under the symbol "MED." MEDIQ Preferred Stock is listed for trading on
the AMEX under the symbol "MED.PR." On April 14, 1998, the last reported sale
price of MEDIQ Common Stock was $13.750 per share and the last reported sale
price of MEDIQ Preferred Stock was $13.375 per share. On January 14, 1998, the
last trading day before public announcement of the execution of the Merger
Agreement, the last sale price of MEDIQ Common Stock as reported on the AMEX was
$11.00 per share. On December 16, 1997, the last day MEDIQ Preferred Stock was
traded before public announcement of the execution of the Merger Agreement, the
last sale price of MEDIQ Preferred Stock as reported on the AMEX was $11.50 per
share (and the last sale price of MEDIQ Common Stock on such date was $11.56).
If the Merger is consummated, the Company anticipates that none of the shares of
the Surviving Corporation's capital stock will be listed on the AMEX or any
other national securities exchange and will not be quoted on the NASDAQ Stock
Market. See "RISK FACTORS--Delisting of MEDIQ Common Stock and MEDIQ Preferred
Stock From AMEX; Uncertainty Regarding Liquidity and Market Price for Series A
Preferred Stock."

other enclosed documents are first being mailed to holders of MEDIQ Stock on or

Required Votes....................  Approval of the Merger and the Merger Agreement requires
                                    (i) the affirmative vote of the holders of a majority of
                                    the outstanding voting power of the MEDIQ Common Stock
                                    and the MEDIQ Preferred Stock, voting together as a
                                    single class and (ii) the affirmative vote of the
                                    holders of a majority of the outstanding shares of MEDIQ
                                    Preferred Stock. With respect to the vote referred to in
                                    clause (i), holders of MEDIQ Common Stock are entitled
                                    to one vote for each share owned by such holder and
                                    holders of MEDIQ Preferred Stock are entitled to ten
                                    votes for each share owned by such holder.
                                    The Rotko Entities collectively own 4,701,464 shares of
                                    MEDIQ Common Stock and 4,730,006 shares of MEDIQ
                                    Preferred Stock, representing approximately 24% of the
                                    outstanding MEDIQ Common Stock (without giving effect to
                                    the conversion of any shares of MEDIQ Preferred Stock
                                    into shares of MEDIQ Common Stock), approximately 75% of
                                    the outstanding MEDIQ Preferred Stock and approximately
                                    63% of the total combined voting power of the MEDIQ
                                    Common Stock and the MEDIQ Preferred Stock, voting
                                    together as a single class (in each case without giving
                                    effect to the exercise of any outstanding options to
                                    acquire MEDIQ Stock). Each Rotko Entity has entered into
                                    a stockholder agreement pursuant to which it has agreed,
                                    subject to certain limitations, that all of the MEDIQ
                                    Stock beneficially owned by such Rotko Entity will be
                                    voted (or caused to be voted) in favor of the Merger
                                    Agreement and the transactions contemplated thereby,
                                    including the Merger (collectively, the "Stockholder
                                    Agreements"). See "THE SPECIAL MEETING--Required Votes"
                                    and "THE STOCKHOLDER AGREEMENTS." The affirmative vote
                                    of the shares of MEDIQ Stock subject to the Stockholder
                                    Agreements will be sufficient to approve the Merger and
                                    the Merger Agreement.
Risks of the Transaction..........  The Merger entails certain special risks with respect to
                                    the shares of Series A Preferred Stock to be received by
                                    holders of MEDIQ Stock in the Merger, in addition to
                                    those risks that are inherent in the Company's business.
                                    The special risks include (i) the fact that a majority
                                    of the outstanding shares of each class of capital stock
                                    of the Surviving Corporation will be held by the
                                    Investors and such persons will therefore control the
                                    Company and have the power to elect a majority of its
                                    directors, appoint new management and approve any action
                                    requiring the approval of the holders of a majority of
                                    any class of its capital stock, (ii) termination of the
                                    listing of the Company's securities on the AMEX, with
                                    the expectation that such delisting, coupled with
                                    concentration of ownership in the Investors and the
                                    Management Stockholders, may prevent the existence or
                                    development of an active trading market for the Series A
                                    Preferred Stock after the Merger and (iii) the
                                    substantial increase in the consolidated indebtedness of
                                    the Company and its subsidiaries in connection with the
                                    Merger will negatively affect the Company's earnings due
                                    to substantially increased interest costs. In addition,
                                    following the Merger, stockholders' equity will decline
                                    from its present level to a deficit of $320.5

                                    million on a pro forma basis as if the Merger and
                                    certain other transactions had occurred on December 31,
                                    1997 (with the further possibility that the equity and
                                    income impairments could adversely affect the Company's
                                    ability to achieve its business strategies and prospects
                                    or to pay dividends on the Series A Preferred Stock to
                                    be issued in the Merger). In addition, the Company's
                                    ability to declare and pay dividends will also be
                                    limited by the terms of the financing arrangements the
                                    Company will enter into as part of the Merger. See "RISK
                                    FACTORS."
Voting of Proxies.................  Shares of MEDIQ Stock represented by a properly executed
                                    proxy (a "Proxy") in the form accompanying this Proxy
                                    Statement/Prospectus received in time for the Special
                                    Meeting will be voted in the manner specified in the
                                    Proxy. Proxies that do not contain any instruction to
                                    vote for or against or to abstain from voting on a
                                    particular matter will be voted in favor of such matter.
                                    Abstentions and broker non-votes will be counted as
                                    present for the purposes of determining whether a quorum
                                    is present but will not be counted as votes cast in
                                    favor of the Merger Agreement. Because the outcome of
                                    the vote on the Merger Agreement and the transactions
                                    contemplated thereby, including the Merger, is based on
                                    the percentage of affirmative votes entitled to be cast
                                    by the holders of all outstanding shares of MEDIQ
                                    Preferred Stock and MEDIQ Common Stock, abstentions and
                                    broker non-votes will have the same effect as a vote
                                    against this proposal. See "THE SPECIAL MEETING--
                                    Required Vote." It is not expected that any matter other
                                    than the proposal to approve and adopt the Merger
                                    Agreement will be brought before the stockholders at the
                                    Special Meeting. If, however, other matters are properly
                                    presented, the persons named as proxies are expected to
                                    vote in accordance with their best judgment with respect
                                    to such matters.
Adjournments;
  Revocability of Proxies.........  If the Special Meeting is adjourned, for whatever
                                    reason, the approval of the Merger Agreement will be
                                    considered and voted upon by stockholders at the
                                    subsequent, reconvened meeting, if any. A stockholder
                                    may revoke a Proxy at any time prior to its exercise by
                                    (i) attending the Special Meeting and voting in person
                                    (although attendance at the Special Meeting will not in
                                    and of itself constitute revocation of a Proxy), (ii)
                                    giving notice of revocation of the Proxy at the Special
                                    Meeting, or (iii) delivering (a) a written notice of
                                    revocation of the Proxy, or (b) a duly executed Proxy
                                    relating to the matters to be considered at the Special
                                    Meeting, bearing a date later than the Proxy previously
                                    executed, to the Secretary of the Company, One MEDIQ
                                    Plaza, Pennsauken, NJ 08110-1460. Unless revoked in one
                                    of the manners set forth above, Proxies in the form
                                    enclosed will be voted at the Special Meeting in
                                    accordance with the instructions set forth therein.
Solicitation of Proxies...........  The cost of soliciting Proxies will be borne by the
                                    Company. The Company may solicit Proxies and the
                                    Company's directors, officers and employees may also
                                    solicit Proxies by telephone, telegram or personal
                                    interview. These persons will receive no additional
                                    compensation for their services. Arrangements will be
                                    made to furnish copies of Proxy materials to
                                    fiduciaries, custodians and brokerage houses for

                                    for their reasonable out-of-pocket expenses. Holders of
                                    MEDIQ Stock should not send stock certificates with
                                    their Proxy cards.
Security Ownership of Management

                                    the Company and their affiliates, including the Rotko
                                    Entities, were beneficial owners of an aggregate of

                                    shares of MEDIQ Preferred Stock (representing
                                    approximately 29% of the outstanding shares of MEDIQ
                                    Common Stock, approximately 78% of the outstanding
                                    shares of MEDIQ Preferred Stock and approximately 66% of

THE MERGER
Conversion of MEDIQ Stock.........  At the Effective Time, MQ will be merged with and into
                                    the Company and the Company will continue as the
                                    surviving corporation in the Merger. Pursuant to the

                                    Common Stock and each issued and outstanding share of
                                    MEDIQ Preferred Stock will be converted into the right
                                    to receive (i) $13.75 in cash, without interest, and
                                    (ii) 0.075 of a share of Series A Preferred Stock,
                                    except for MEDIQ Shares owned directly or indirectly by
                                    MQ or the Company, the Rolled Shares and Dissenting
                                    Shares. Each MEDIQ Share that is issued and outstanding

                                    Corporation that the current holders of MEDIQ Shares,
                                    other than the Rotko Entities and the Management

                                    Preferred Stock. Ownership of Series A Preferred Stock
                                    will not entitle or permit such holders to vote on any
                                    matter required or permitted to be voted upon by the
                                    stockholders of the Company, except as otherwise
                                    required by Delaware law; provided that, without the
                                    affirmative vote or written consent of the holders of a
                                    majority of the outstanding shares of Series A Preferred
                                    Stock, the Company will not (i) create, authorize or
                                    issue any other class or series of stock entitled to a
                                    preference prior to Series A Preferred Stock upon any
                                    dividend or distribution or any liquidation,
                                    distribution of assets, dissolution or winding up of the
                                    Company, or (ii) amend, alter or repeal any provision of
                                    the Company's Certificate of Incorporation so as to
                                    materially adversely affect the relative rights and
                                    preferences of the Series A Preferred Stock. Upon
                                    consummation of the Merger, the Investors will, in the
                                    aggregate, own a majority of the outstanding shares of
                                    Series A Preferred Stock.

Rotko Interests...................  Pursuant to the terms of the Stock Option Agreement
                                    dated January 14, 1998, by and among MQ and the Rotko
                                    Entities (the "Stock Option Agreement"), the Rotko
                                    Entities granted MQ an irrevocable option (the "Rotko
                                    Option") to purchase, under certain circumstances, at a
                                    cash exercise price of $14.50 per share, up to 4,701,464
                                    shares of MEDIQ Common Stock owned by the Rotko Entities
                                    (which represents approximately 24% of the total
                                    outstanding MEDIQ Common Stock as of January 14, 1998)

                                    see "STOCK OPTION AGREEMENT."
                                    As a condition to entering into the Merger Agreement, MQ
                                    required that the Rotko Entities enter into an agreement
                                    with MQ dated January 14, 1998 (the "Rollover
                                    Agreement"). Pursuant to the Rollover Agreement, the
                                    Rotko Entities have agreed to convert an aggregate of
                                    1,000,000 shares (the "Rolled Shares") of MEDIQ

                                    foregoing provisions and certain other provisions of the
                                    Rollover Agreement, see "THE ROLLOVER AGREEMENT."
                                    Pursuant to the Stockholder Agreements, the Rotko
                                    Entities have agreed, among other things and subject to
                                    certain conditions, to vote in favor of the Merger and
                                    the Merger Agreement. See "THE STOCKHOLDER AGREEMENTS."
Conversion of MQ Stock............  As a result of the Merger, each share of capital stock
                                    of MQ issued and outstanding immediately prior to the
                                    Effective Time, including any shares of capital stock
                                    issued by MQ to the Rotko Entities in exchange for the
                                    Rolled Shares, will be converted into and will represent
                                    the same number of shares of the same class of capital
                                    stock of the Surviving Corporation, provided that each
                                    of the Rolled Shares not owned by MQ immediately prior
                                    to the Effective Time will be converted into and
                                    thereafter represent the number of shares of capital
                                    stock of the Surviving Corporation as set forth in the

                                    the best interests of the holders of MEDIQ Common Stock,
                                    (ii) determined that the Merger, the Merger Agreement

                                    and in the best interests of the holders of MEDIQ
                                    Preferred Stock, and (iii) recommended that holders of
                                    MEDIQ Common Stock and holders of MEDIQ Preferred Stock

Opinion of the Company's Financial
  Advisor.........................  Smith Barney Inc. (now associated with Salomon Brothers
                                    Inc and collectively with Salomon Brothers Inc doing
                                    business as, and herein referred to as, "Salomon Smith
                                    Barney") has acted as financial advisor to the Company
                                    in connection with the Merger and has delivered to the
                                    Board of Directors of the Company a written opinion
                                    dated January 14, 1998 to the effect that, as of the
                                    date of such opinion and based upon and subject to
                                    certain matters stated therein, the Merger Consideration
                                    was fair, from a financial point of view, to the holders
                                    of MEDIQ Shares (other than the Rotko Entities and the
                                    Management Stockholders, as to which Salomon Smith
                                    Barney was not asked to opine). The full text of the
                                    written opinion of Salomon Smith Barney dated January
                                    14, 1998, which sets forth the assumptions made, matters
                                    considered and limitations on the review undertaken, is
                                    attached as Annex B to this Proxy Statement/ Prospectus
                                    and should be read carefully in its entirety. THE
                                    OPINION OF SALOMON SMITH BARNEY IS DIRECTED TO THE BOARD
                                    OF DIRECTORS OF THE COMPANY AND RELATES ONLY TO THE
                                    FAIRNESS OF THE MERGER CONSIDERATION FROM A FINANCIAL
                                    POINT OF VIEW, DOES NOT ADDRESS ANY OTHER ASPECT OF THE
                                    MERGER OR RELATED TRANSACTIONS AND DOES NOT CONSTITUTE A
                                    RECOMMENDATION TO ANY STOCKHOLDER AS TO HOW SUCH
                                    STOCKHOLDER SHOULD VOTE AT THE SPECIAL MEETING. See
                                    "SPECIAL FACTORS--Opinion of the Company's Financial
                                    Advisor."
Fractional Shares.................  No certificates or scrip representing fractional shares
                                    of Series A Preferred Stock will be issued in connection
                                    with the Merger, and such fractional share interests
                                    will not entitle the owner thereof to vote or to any
                                    rights of a stockholder of the Surviving Corporation
                                    after the Merger. Each holder of MEDIQ Shares exchanged
                                    pursuant to the Merger who would otherwise have been
                                    entitled to receive a fractional share of Series A
                                    Preferred Stock (after taking into account all MEDIQ
                                    Shares delivered by such holder) will receive, in lieu
                                    thereof, a cash payment (without interest) therefor
                                    determined as provided herein. See "THE MERGER--
                                    Fractional Shares."
Conditions to the Merger..........  The obligations of the Company and MQ to consummate the
                                    Merger are subject to various conditions, including,
                                    without limitation, the approval of the Merger Agreement
                                    and the transactions contemplated thereby by the holders
                                    of the requisite number of shares of MEDIQ Common Stock
                                    and MEDIQ Preferred Stock, the termination or expiration
                                    of the relevant waiting period under the
                                    Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
                                    amended (the "HSR Act") (which termination was granted
                                    on February 24, 1998), the effectiveness of the
                                    Registration Statement, the dissemination of this Proxy
                                    Statement/Prospectus and the Schedule 13E-3, the absence
                                    of pending material litigation intended to prevent the
                                    Merger by any governmental entity (or by any other
                                    person, which has a reasonable likelihood of success),
                                    and the absence of any injunction or other legal
                                    restraint or prohibition preventing the consummation of
                                    the Merger. See "REGULATORY APPROVALS." MQ's obligations
                                    to effect the Merger are further subject, among other
                                    things, to (i) the continuing truth in all material
                                    respects of the Company's representations made in

                                    obligations of the Company under the Merger Agreement,

                                    described in the commitment letters MQ has received from
                                    financial institutions with respect to amounts
                                    sufficient to consummate the transactions contemplated
                                    by the Merger Agreement on the terms and conditions set
                                    forth therein (or on such other terms and conditions, or
                                    involving such other financing sources, as are
                                    acceptable to MQ in its sole discretion), (iv) the Rotko
                                    Entities' performance of their obligations under the
                                    Rollover Agreement, and (v) the number of Dissenting
                                    Shares not exceeding 15% of the outstanding MEDIQ
                                    Shares. See "SOURCES AND AMOUNT OF FUNDS." The Company's
                                    obligations to effect the Merger are further subject to
                                    the continuing truth of MQ's representations made in the
                                    Merger Agreement, the performance of all material
                                    obligations of MQ under the Merger Agreement and the
                                    absence of pending material litigation intended to
                                    prevent the Merger by any governmental entity (or by any
                                    other person, which has a reasonable likelihood of
                                    success). The Company and MQ presently believe that the
                                    pending lawsuit challenging the Merger is without merit
                                    and does not have a reasonable likelihood of success and
                                    accordingly do not expect such litigation to result in a
                                    condition to the Merger failing to be satisfied. The
                                    Company and MQ may, to the extent permitted by
                                    applicable law, waive the conditions to their obligation
                                    to consummate the Merger; however, no such waivers are
                                    presently contemplated. See "CERTAIN PROVISIONS OF THE
                                    MERGER AGREEMENT-- Conditions," "THE MERGER--Conditions
                                    to the Consummation of the Merger" and "THE COMPANY--
                                    Stockholder Litigation."
Termination of the Merger
  Agreement.......................  The Merger Agreement may be terminated at any time,
                                    notwithstanding approval thereof by the requisite vote
                                    of the Company's stockholders, prior to the Effective
                                    Time (i) by mutual written consent of MQ and the
                                    Company, (ii) by either party if such party's obligation
                                    to consummate the transactions contemplated in the
                                    Merger Agreement shall have become impossible to
                                    satisfy, (iii) by either party if the Merger has not
                                    been consummated on or before August 31, 1998 (other
                                    than due to the failure of the party seeking to
                                    terminate the Merger Agreement to perform its
                                    obligations under the Merger Agreement at or prior to
                                    the Effective Time), (iv) by either party if the other
                                    party is in breach at any time prior to the Effective
                                    Time of any of the representations and warranties made
                                    by such party as though made on and as of such date and
                                    such breach would reasonably be expected to have a
                                    "material adverse effect" (as defined in the Merger
                                    Agreement), (v) by either party if, after a cure period,
                                    the other party shall not have performed and complied in
                                    all material respects with all covenants required by the
                                    Merger Agreement to be performed or complied with by it
                                    on and as of such date, or (vi) by MQ or the Company in
                                    certain other situations, including in connection with a
                                    Superior Proposal (as defined in the Merger Agreement).
                                    Under certain circumstances related to a third party

                                    termination of the Merger Agreement prior to the
                                    Effective Time will result in the payment of a break-up
                                    fee of $16,500,000 plus expenses by the Company to MQ.
                                    See "CERTAIN PROVISIONS OF THE MERGER AGREEMENT--

                                    Transactions."
Regulatory Approvals..............  On February 10, 1998, the Company and BRS each filed a
                                    notification report together with requests for early
                                    termination of the waiting period under the HSR Act with
                                    the Federal Trade Commission (the "FTC") and the
                                    Antitrust Division of the Department of Justice (the
                                    "Antitrust Division") in respect of the Merger and the
                                    related transactions. On February 24, 1998, the FTC and
                                    the Antitrust Division granted early termination of the
                                    waiting period under the HSR Act with respect to the
                                    Merger effective immediately. See "REGULATORY
                                    APPROVALS."
 
CERTAIN FEDERAL INCOME TAX
  CONSEQUENCES....................  The receipt of cash and Series A Preferred Stock by a
                                    stockholder pursuant to the Merger will be treated as a
                                    sale of stock generating capital gain (or loss) equal to
                                    the sum of (i) the cash received and (ii) the fair
                                    market value of the Series A Preferred Stock received
                                    less the stockholder's basis in the stock surrendered in
                                    the Merger. The Company may, in certain circumstances,
                                    be required to withhold tax from cash paid to
                                    stockholders. See "SPECIAL FACTORS-- Federal Income Tax
                                    Consequences."
 
TREATMENT OF MEDIQ
  STOCK OPTIONS...................  Upon the consummation of the Merger, each option to
                                    acquire MEDIQ Shares outstanding immediately prior to
                                    the Effective Time under the Company's stock option
                                    plans or similar arrangements, whether vested or
                                    unvested (each, an "Option," and collectively, the
                                    "Options"), will automatically become immediately
                                    exercisable and each holder of an Option will have the
                                    right to receive from the Company in respect of each
                                    MEDIQ Share underlying the Option (less applicable
                                    withholding taxes) (i) a cash payment in an aggregate
                                    amount equal to the difference between the cash portion
                                    of the Merger Consideration of $13.75, less the exercise
                                    price per MEDIQ Share applicable to such Option as
                                    stated in the applicable stock option agreement or other
                                    agreement plus (ii) 0.075 of a share of Series A
                                    Preferred Stock (the "Option Consideration"). From and
                                    after the Effective Time, Option holders will not have
                                    any other rights in respect thereof other than to
                                    receive payment for their Options as set forth herein.
                                    The Company has agreed to take all reasonably necessary
                                    actions to terminate its stock option plans and similar
                                    arrangements. The foregoing terms are subject to the
                                    Company obtaining any required consents from the holders
                                    of any Options and the making of any necessary
                                    amendments to the Company's stock option plans and other
                                    similar agreements. See "CERTAIN PROVISIONS OF THE
                                    MERGER AGREEMENT--Option Consideration."
 
INTERESTS OF CERTAIN PERSONS IN
  THE MERGER......................  In considering the recommendations of the Special
                                    Committee and the Board with respect to the Merger,
                                    stockholders should

                                    be aware that certain officers and directors of the
                                    Company and affiliates, associates and persons related
                                    to the officers and directors have interests in
                                    connection with the Merger that are different from, or
                                    in addition to, the interests of the Company's
                                    stockholders generally. The Special Committee and the
                                    Board of Directors were aware of these interests and
                                    considered them in addition to the other matters
                                    described under "SPECIAL FACTORS--Recommendation of the
                                    Special Committee and the Board of Directors; Reasons
                                    for the Merger."
                                    The employment agreements with the Company's President
                                    and Chief Executive Officer, Thomas E. Carroll, its
                                    Chief Financial Officer, Jay M. Kaplan, and Michael F.
                                    Sandler, a director of the Company and its former Chief
                                    Financial Officer, include provisions entitling those
                                    persons to bonuses paid in connection with the sale of
                                    the Company, calculated based, in the cases of Messrs.
                                    Carroll and Kaplan, upon the aggregate purchase price
                                    paid for the Company and, in the case of Mr. Sandler,
                                    upon the value received by the Company's stockholders in
                                    a sale of the Company. Upon consummation of the Merger,
                                    the Company expects to pay a bonus of approximately $3.9
                                    million to Mr. Carroll, a bonus of approximately
                                    $390,000 to Mr. Kaplan and a bonus of approximately $1.3
                                    million to Mr. Sandler. Under his employment agreement,
                                    Mr. Carroll is also entitled to receive an additional
                                    payment from the Company to compensate him for
                                    liabilities, if any, imposed under Section 4999 of the
                                    Internal Revenue Code of 1986, as amended (the "Code"),
                                    or any successor provision thereto. See "SPECIAL
                                    FACTORS-- Interests of Certain Persons in the Merger."
                                    The Options held by officers of the Company, including
                                    Options that have not yet vested, will be treated in the
                                    same manner as Options held by non-officers, as
                                    described under "THE MERGER--Option Consideration."
                                    Under the terms of the Company's deferred compensation
                                    plan, approximately $1.6 million of previously deferred
                                    employee compensation will become payable, upon
                                    consummation of the Merger, to certain former members of
                                    senior management who previously deferred such
                                    compensation. Deferred compensation will be paid to
                                    employees only at their election. The officers of the
                                    Company will remain in place after the Merger and their
                                    current employment agreements will remain in effect. In
                                    addition, the Management Stockholders will purchase
                                    shares of capital stock of the Surviving Corporation
                                    after the Merger and will be granted certain options to
                                    purchase additional shares of capital stock of the
                                    Surviving Corporation, as set forth in "SPECIAL
                                    FACTORS--Interests of Certain Persons in the Merger."
                                    In connection with the Merger it is currently expected
                                    that the Management Stockholders will acquire an
                                    aggregate of approximately 61,000 shares of the
                                    Surviving Corporation Common Stock representing
                                    approximately 6.1% of the outstanding shares of
                                    Surviving Corporation Common Stock, approximately
                                    201,549 shares of Series A Preferred Stock (not
                                    including shares of Series A Preferred Stock to be

                                    outstanding Surviving Corporation Common Stock on a
                                    fully diluted basis and will also have the opportunity
                                    to receive options to acquire securities of the
                                    Surviving Corporation, representing approximately 2.8%
                                    of the outstanding Surviving Corporation Common Stock,
                                    on a fully diluted basis. No final determination as to
                                    the identity of such persons or the amount of such
                                    shares to be acquired by any individual Management
                                    Stockholder, or the Managment Stockholders in the
                                    aggregate, has been made.

                                    Effective Time in respect of the Transactions (as
                                    defined herein) and thereafter will receive an annual

                                    agree to or otherwise assist in the effectuation of any
                                    such transaction; provided, however, that nothing in the
                                    Stockholder Agreements will prohibit any Rotko Entity
                                    from taking any action in his capacity as a director or
                                    officer of the Company to the extent such director or
                                    officer would be permitted to take such action under the
                                    Merger Agreement. For a summary of the foregoing
                                    provisions and certain other provisions of the

                                    AGREEMENTS." The existence of the Stockholder Agreements
                                    may have the effect of discouraging persons who might
                                    now or prior to the Effective Time be interested in
                                    acquiring all of or a significant interest in, or
                                    otherwise effecting a business combination with, the
                                    Company from considering or proposing such a
                                    transaction.
 
STOCK OPTION AGREEMENT............  Pursuant to the terms of the Stock Option Agreement, the
                                    Rotko Entities granted MQ an irrevocable option to
                                    purchase, under certain circumstances, at a cash
                                    exercise price of $14.50 per share, up to 4,701,464
                                    shares of MEDIQ Common Stock owned by the Rotko Entities
                                    (which represents approximately 24% of the total
                                    outstanding MEDIQ Common Stock) and 4,730,006 shares of
                                    MEDIQ Preferred Stock owned by the Rotko Entities (which
                                    represents approximately 75% of the outstanding MEDIQ
                                    Preferred Stock). The Rotko Option becomes exercisable
                                    only upon the occurrence of a Purchase Event (as such
                                    term is defined in the Stock Option Agreement). To the
                                    extent the Rotko Option has not been previously
                                    exercised, it will terminate and be of no further force
                                    and effect upon the earlier to occur of (i) the
                                    Effective Time of the Merger; (ii) termination of the
                                    Merger Agreement in accordance with certain of its
                                    termination provisions and (iii) in the case of any
                                    other termination of the Merger Agreement, the date that
                                    is 6 months following such termination (such date, the
                                    "Termination Date"). In the event MQ exercises the Rotko
                                    Option prior to the Effective Time, the MEDIQ Shares
                                    received by MQ would be canceled and would not be
                                    entitled to be converted into any Merger Consideration
                                    in the Merger. For a summary of the foregoing provisions
                                    and certain other provisions of the Stock Option
                                    Agreement, see "STOCK OPTION AGREEMENT." The existence
                                    of the Stock Option Agreement may have the effect of
                                    discouraging persons who might now or prior to the
                                    Effective Time be interested in acquiring all of or a
                                    significant interest in, or otherwise effecting a
                                    business combination with, the Company from considering
                                    or proposing such a transaction.
 
THE ROLLOVER AGREEMENT............  As a condition to entering into the Merger Agreement, MQ
                                    required that the Rotko Entities enter into the Rollover

                                    agreed that either (i) immediately prior to the
                                    Effective Time, the Rotko Entities will transfer the

                                    equal to approximately 11.0% (assuming an initial
                                    investment of $10.0 million in such common stock by the

         SELECTED CONSOLIDATED HISTORICAL AND PRO FORMA FINANCIAL DATA
    
 
   
    The following table sets forth selected consolidated historical financial
data of the Company for the last five completed fiscal years and the first
quarter of fiscal 1998. The Statement of Operations Data for the years ended
September 30, 1993-1997 and the Balance Sheet Data as of September 30, 1993-1997
were derived from audited Consolidated Financial Statements of the Company. The
Statement of Operations Data for the quarter ended December 31, 1997 and the
Balance Sheet Data as of December 31, 1997 were derived from the unaudited
Consolidated Financial Statements of the Company included in the Company's
Quarterly Report on Form 10-Q for the quarter ended December 31, 1997. The Other
Data was derived from Company-prepared schedules. The selected unaudited pro
forma financial data has been derived from the Pro Forma Financial Statements
(as defined herein) included elsewhere herein. The "Pro Forma Transactions"
Balance Sheet Data gives effect to the Transactions as if they were consummated
on December 31, 1997. The "Pro Forma Transactions Including CHI" Balance Sheet
Data gives effect to the Transactions and the CHI Acquisition as if they were
consummated on December 31, 1997. The "Pro Forma Transactions" Statement of
Operations Data gives effect to the Transactions and the Company's acquisition
of the 50% interest in SpectraCair that it did not already own (the "SpectraCair
Acquisition") as if they were consummated on October 1, 1996. The "Pro Forma
Transactions Including CHI" Statement of Operations Data gives effect to the
Transactions, the SpectraCair Acquisition and the CHI Acquisition as if they
were consummated on October 1, 1996. The pro forma financial information is
based on assumptions that management believes are reasonable and such
information is presented for comparative and informational purposes only. The
pro forma financial information does not purport to represent what the Company's
results of operations or financial condition would actually have been had the
Transactions, the SpectraCair Acquisition and the CHI Acquisition in fact
occurred on such dates or to project the Company's results of operations for any
future period or financial condition on any future date. This table should be
read in conjunction with the Pro Forma Financial Statements included elsewhere
herein and the Company's Annual Report on Form 10-K for the year ended September
30, 1997, as amended, the Company's Quarterly Report on Form 10-Q for the
quarter ended December 31, 1997, the Consolidated Financial Statements of the
Company and related notes thereto, the financial statements of CH Medical and
the related notes thereto filed as an exhibit to the Registration Statement, and
the other financial information contained in the documents included or
incorporated by reference herein. See "INCORPORATION OF CERTAIN DOCUMENTS BY
REFERENCE." See "THE COMPANY--Growth Strategy" and "--CHI Acquisition."

Notes to Selected Historical and Pro Forma Financial Data
    
 
(1) On September 30, 1994, MEDIQ/PRN acquired the critical care and life support
    rental equipment inventory of Kinetic Concepts, Inc. The purchase price,
    which was primarily financed with long-term debt, approximated $88.0
    million, including transaction costs and the assumption of certain capital
    lease obligations.
 
   
(2) On September 1, 1997, the Company acquired the remaining 50% interest in
    SpectraCair not previously owned by it for $1.9 million and the assumption
    of its former joint venture partner's portion of the outstanding debt of
    $4.4 million. Accordingly, the results of operations of SpectraCair for the
    one month ended September 30, 1997, are included in the Company's fiscal
    1997 operating results.
    
 
(3) Fiscal 1996 includes a $2.2 million restructuring charge.
 
(4) Fiscal 1993 includes interest income of $1.1 million partially offset by a
    $0.3 million net loss on the sale of assets.
 
    Fiscal 1994 includes a net gain on the sale of assets of $5.8 million and
    interest income of $1.4 million.
 
    Fiscal 1995 includes $1.5 million of interest income partially offset by a
    $0.4 million net loss on the sale of assets.
 
    Fiscal 1996 includes a $6.0 million reserve on the note receivable from MHM
    Services, Inc. ("MHM"), interest income of $1.5 million and a net gain on
    the sale of assets of $0.6 million.
 
   
    Fiscal 1997 includes an equity participation charge related to the
    repurchase of MEDIQ/PRN warrants of $11.0 million, a gain on the sale of
    stock of $9.2 million, a reserve on amounts due from MHM of $5.5 million,
    the write-off of deferred acquisition costs of $4.0 million, a gain on a
    note receivable of $1.8 million and interest income of $2.1 million.
    
 
   
    The three months ended December 31, 1997, include $0.2 million of interest
    income.
    
 
   
(5) Earnings per share have been restated in accordance with Statement of
    Financial Accounting Standards No. 128, Earnings Per Share ("SFAS 128"). In
    accordance with SFAS 128, since the Company has incurred losses from
    continuing operations for the years ended September 30, 1993-1997, no
    potential common shares have been included in the computation of any diluted
    per share amount. Accordingly, only basic earnings per share have been
    presented for all periods. For the three months ended December 31, 1997,
    earnings per share assuming dilution was $.05 and weighted average shares
    outstanding were 26,556,000.
    
 
(6) Includes sales of parts, disposables and equipment, outsourcing and
    management consulting.
 
(7) EBITDA is defined as income from continuing operations before interest,
    taxes, depreciation and amortization. EBITDA is presented because it is a
    widely accepted financial indicator of a company's ability to service
    indebtedness. However, EBITDA should not be considered as an alternative to
    income from operations or to cash flows from operating activities (as
    determined in accordance with generally accepted accounting principles) and
    should not be construed as an indication of a company's operating
    performance or as a measure of liquidity.
 
(8) EBITDA divided by total revenues.
 
   
(9) Represents the ratio of earnings to combined fixed charges and preferred
    stock dividends. In fiscal years 1993 through 1996, earnings were inadequate
    to cover combined fixed charges and preferred stock dividends by $11,046,
    $13,324, $3,658 and $6,556, respectively. Earnings were also inadequate to
    cover combined fixed charges and preferred stock dividends in the pro forma
    and combined periods ended September 30, 1997, and December 31, 1997, by
    $52,621, $52,667, $12,835 and $12,562, respectively.
    
 
   
(10) Represents stockholders' equity divided by weighted average MEDIQ Shares
    outstanding.

                                SPECIAL FACTORS
 
    Holders of MEDIQ Stock should carefully consider the following factors in
connection with their consideration of the Merger. See also "FORWARD-LOOKING
STATEMENTS" and "RISK FACTORS" elsewhere in this Proxy Statement/Prospectus.
 
BACKGROUND OF THE MERGER
 
    In November 1994, the Company formed a special committee of the Board of
Directors for the purpose of exploring alternative ways to maximize stockholder
value, including the possible sale or restructuring of the Company. The special
committee consisted of Mr. Rotko, Chairman of the Company's Board of Directors,
Mr. Miller, who had from time to time acted as a professional advisor to the
Rotko family, Dr. Shipon, Mr. Rotko's brother-in-law, and Bernard Korman, the
then-Chief Executive Officer of the Company. Other than Mr. Korman, who resigned
from the special committee in December 1994, none of the special committee
members were employees of the Company during their service as members of the
special committee.
 
   
    In January 1995, the Company retained a financial advisor to assist the
special committee. Subsequently, in January 1995, a corporation that was
organized by Archon Capital Partners, L.P. ("Archon"), in conjunction with
certain members of management led by Mr. Korman and including Messrs. Carroll
and Sandler, made an unsolicited offer to acquire the Company. Mr. Carroll's
participation in the Archon offer ceased in March 1995. Mr. Carroll is the Chief
Executive Officer of the Company and Messrs. Carroll and Sandler are members of
the Board of Directors.
    
 
    Archon offered to acquire the stock of the Company for a price of $5.00 per
share to non-controlling shareholders and, with respect to controlling
shareholders, alternatively either (i) $5.75 per share or (ii) $4.00 per share
in cash and interests, then owned by the Company, in PCI Services, Inc. and
NutraMax Products, Inc. ("NutraMax") valued at approximately $2.31 per MEDIQ
share. Following receipt of the Archon offer, the special committee determined
that the Company's financial advisor should conduct a market check to determine
the interest of unrelated third parties in the Company.
 
    Beginning in March 1995, the Company solicited, with the assistance of its
financial advisor, indications of interest from potential buyers for the Company
and received a number of proposals from interested parties. Potential buyers
were selected based on their likely interest in, and financial ability to
consummate, an acquisition of the Company. Fifty-two potential buyers were
solicited.
 
    In April 1995, the Board accepted the recommendation of the special
committee, based on the assessment of the Company's financial advisor that the
value of the Archon offer was below the low end of the value for the Company, to
reject that offer as inadequate. Also in April, the Company entered into
agreements with certain key executives that provided for the payment of "success
bonuses" upon the occurrence of certain strategic transactions involving the
Company, including the sale of the Company. See "SPECIAL FACTORS--Interests of
Certain Persons in the Merger." The success bonuses were adopted to create an
additional incentive for management to remain with the Company and maximize
shareholder value in the sale of the Company.
 
   
    In June 1995, the special committee received five third-party proposals.
Three of the proposals were for the acquisition of all of the stock of the
Company, with the assets of the Company other than PRN Holdings, Inc. ("PRN") to
be contributed to a liquidating trust, the equity interests in which would be
distributed to the Company's stockholders. Under those proposals, the estimated
distributable value per share of MEDIQ Stock ranged from $6.19 to $6.78. The
fourth proposal, for only the assets of PRN, would have resulted in
substantially less distributable value to the Company's stockholders. The fifth
proposal, also for the assets of PRN, would have resulted in negative
distributable value to the Company's stockholders.
    
 
                                       25
<PAGE>
    After extensive review of the three proposals with the highest proposed
aggregate financial return to the Company's stockholders, in July 1995 the
special committee authorized its representatives to negotiate with the top two
bidders (each of which required the establishment of a liquidating trust) and
invite each to submit its best and final offer. Thereafter, one of the top two
bidders withdrew its proposal.
 
    By early September 1995, following extended negotiations with the remaining
bidder, the special committee had made substantial progress toward reaching an
agreement for the sale of the Company. Subsequently, that bidder reduced its
valuation of the Company and, accordingly, its bid for the Company. In response,
the special committee and its advisors concluded that the reduced valuation and
bid were unsatisfactory. Thereafter, at the request of the special committee,
its representatives contacted the two next highest bidders to determine whether
they remained interested in acquiring the Company. Discussions with those
bidders were held in September and October 1995.
 
   
    On October 18, 1995, one of the two final bidders submitted a written
proposal to acquire the outstanding capital stock of PRN for an estimated total
value per share of MEDIQ Stock of $5.40. The other bidder's proposal, to acquire
the outstanding capital stock of PRN for an estimated total value per share of
MEDIQ Stock of $5.74, was communicated orally to representatives of the special
committee.
    
 
   
    The special committee met on October 19, 1995 to consider the two proposals
and discuss whether to recommend acceptance of one of the bids for PRN or to
negotiate further with the prospective bidders and whether to continue with an
auction process or, in light of the significant diversion of management time and
resources required by the auction process, to cease further efforts to sell the
Company at that time and continue to operate the Company as a stand-alone
business, either without divestitures of non-core businesses or with
divestitures that would enable management to focus its efforts on the Company's
core PRN business. At that meeting, the special committee resolved to recommend
to the Board that the Company terminate any further efforts to sell the Company
at that time. It was the consensus of the special committee that the bids did
not accord sufficient value to the potential of certain opportunities for the
Company's PRN business. The higher of the two final bids was at the low end of
the range of fair values of the Company prepared by the Company's financial
advisor. The other bid was lower, and both bids were highly conditional. At a
subsequent meeting of the Board, the special committee's recommendation was
accepted and the Board determined to continue its strategy (first announced in
November 1990) of divesting non-core assets and using the divestiture proceeds
to reduce indebtedness. This program was substantially completed by the fall of
1996 and included the transactions discussed below.
    
 
    In July 1996, PCI Services, Inc. ("PCI") agreed to be acquired by Cardinal
Health, Inc. ("Cardinal"). In exchange for its 46% interest in PCI the Company
received shares of Cardinal stock which it subsequently sold for approximately
$88.4 million.
 
   
    In September 1996, the Company entered an agreement with NutraMax pursuant
to which NutraMax agreed to repurchase all of the shares of NutraMax common
stock (the "NutraMax Common Stock") owned by the Company for an aggregate
purchase price of approximately $36.3 million.
    
 
    Also in 1996, the Company agreed to sell its ownership interest in
HealthQuest, Inc. for $75,000, and sold substantially all of the assets of MEDIQ
Mobile X-Ray Services, Inc. ("Mobile X-Ray") for (i) approximately $5.3 million
in cash, (ii) shares of Integrated Health Services common stock with an initial
value of $5.2 million (which shares were subsequently sold), and (iii) the
possibility of the Company receiving additional cash consideration based upon
the occurrence of certain future events. In fiscal year 1997, the Company
received approximately $1.1 million in additional cash consideration relating to
the Mobile X-Ray transaction.
 
    In May 1997, the Company sold the stock of Health Examinetics, Inc. for $1.7
million.
 
    In November 1997, the Company sold to InnoServ Technologies ("InnoServ") all
of the 2,026,438 shares of InnoServ common stock owned by it, as well as a
warrant to acquire additional shares of InnoServ common stock. Under the terms
of that agreement, no cash payment was made by InnoServ. The parties
 
                                       26
<PAGE>
agreed, however, to terminate a non-compete covenant relating to maintenance and
repair services. In addition, in the event of a change of control of InnoServ
before September 30, 1998, the Company will be entitled to certain payments from
the acquiring party.
 
    In the fall of 1996, with the implementation of the Company's strategic plan
to dispose of non-core assets and apply the proceeds thereof to reduce
indebtedness nearing completion, the Company engaged Salomon Smith Barney to
advise the Company in respect of strategic alternatives, including the possible
sale of the Company and the acquisition of companies with complementary
businesses. The Company had identified Universal Hospital Services, Inc., a
corporation that rents movable medical equipment to hospitals and other
healthcare providers ("UHS"), as an attractive potential acquisition candidate
which complemented the Company's core equipment rental business. Accordingly,
Salomon Smith Barney was asked to assist the Company in connection with a
possible transaction with UHS.
 
   
    In late 1996 and early 1997, the Company focused its efforts on a possible
transaction with UHS and the potential growth in the Company's core equipment
rental businesses which would have resulted from the acquisition of UHS. In
February 1997, the Company agreed to acquire all of the outstanding shares of
UHS for an aggregate purchase price (including refinancing of indebtedness) of
approximately $138 million. In April 1997, the stockholders of UHS approved the
acquisition subject to federal regulatory approval pursuant to the HSR Act. In
July 1997, the Company and UHS were informed by the FTC that it had authorized
its staff to take legal action to block the proposed transaction and,
subsequently, the FTC filed a motion for a preliminary injunction to block the
transaction. In September 1997, facing the likelihood of a protracted
administrative proceeding before the FTC, the uncertainty of the outcome and the
costs associated with continuing to defend against the efforts of the FTC to
prevent the transaction, the Company and UHS mutually terminated their
agreement.
    
 
    During the summer of 1997, the Board of Directors also reviewed the
implementation of the Company's strategic plan and its belief that the trading
range of MEDIQ Stock did not necessarily reflect the value of the Company and
the benefits the Company had realized and expected to realize from its focus on
its core business and growth opportunities. At that time, the Board considered
resuming a process designed to explore strategic alternatives and maximize
stockholder value, but deferred any action pending resolution of the proposed
transaction with UHS.
 
    Following termination in September 1997 of the agreement between the Company
and UHS, the Board determined to explore a possible sale of the Company and, on
October 17, 1997, the Executive Committee of the Board (the "Executive
Committee") met with executive management, the Company's legal counsel and
Salomon Smith Barney. At that meeting, the Executive Committee assessed the
Company's current market valuation and stock price performance and discussed the
possibility of enhancing stockholder value through the sale of the Company. In
addition, the Executive Committee discussed with the Company's legal and
financial advisors the principal anticipated events and timing of an auction
process. After discussion and evaluation of different transaction scenarios, the
Executive Committee authorized Salomon Smith Barney to conduct an auction on
behalf of the Company, in which bids for the acquisition of the Company would be
solicited with the goal of maximizing value for all stockholders. At that time,
the Rotko Entities advised the Company that they did not intend to seek any
treatment from any bidder different from that to be available to the Company's
other stockholders.
 
    On October 29, 1997, the Company issued a press release stating that the
Company had authorized Salomon Smith Barney to explore strategic alternatives,
including the possible sale of the Company. A confidential memorandum (the
"Confidential Memorandum") was then prepared for distribution to potential
buyers and a list of potential buyers to be contacted directly in respect of
their interest in a possible transaction was assembled.
 
    Between October 17 and November 17, 1997, approximately 50 potential buyers
were contacted. Potential buyers were selected based on their likely interest
in, and financial ability to consummate, an acquisition of the Company. In
addition, following the October 29 press release, Salomon Smith Barney
 
                                       27
<PAGE>
was contacted directly by a number of potential buyers, who were then considered
for participation in the process. Confidentiality and standstill agreements were
entered into with the 39 potential buyers that expressed an interest in the
Company and, beginning on October 31, 1997, copies of the Confidential
Memorandum, along with a letter setting forth the procedures of the auction
process, the deadline for firm offers and other bidding requirements, were sent
to such potential buyers.
 
    By the week of November 17, 1997, 20 written indications of interest had
been received from potential buyers. On November 21, 1997, at a regular meeting
of the Executive Committee, the Executive Committee reviewed with executive
management and the Company's legal and financial advisors the status of the
auction process and the identities of various potential buyers. The Executive
Committee was informed that the indications of interest submitted by 17 of the
20 potential buyers contemplated that the acquisition of the Company would be
treated as a recapitalization for financial reporting purposes.
 
    After conferring with executive management and the Company's legal and
financial advisors, the Executive Committee authorized Salomon Smith Barney to
contact the parties that had proposed the six highest prices for the Company,
five of which were financial buyers. The five financial buyers were invited,
after an opportunity for further due diligence and presentations from
management, to make a definitive proposal to acquire the Company. The other
potential buyer, an entity with an existing business in the Company's industry,
was asked to ascertain its level of confidence regarding the antitrust issues
involved in a transaction with the Company. After further discussions with
representatives of such potential buyer, that party elected not to pursue
further negotiations with the Company. Another potential financial buyer
subsequently was included in the final group after indicating that it expected
to increase its bid to be competitive with the other remaining bidders.
 
    On November 24, 1997, at a regular meeting of the Board of Directors, the
Board, executive management and the Company's legal counsel discussed the
results of the Company's requests for indications of interest and considered the
six potential buyers that had been invited to proceed in the auction process.
Also at that meeting, the Board affirmed the actions taken by the Executive
Committee at its meeting on November 21 in authorizing the progress of the
auction into a second round and selecting second round bidders.
 
    The six potential buyers were informed of their invitation to proceed and
given access to a special "Data Room" established by the Company that contained
detailed information concerning the Company. The six potential buyers were also
given the opportunity to meet with senior management of the Company and visit
the Company's headquarters. From December 3, 1997 through January 8, 1998, each
of the six potential buyers conducted extensive meetings with members of the
Company's senior management, including the chief executive officer, chief
financial officer and senior vice presidents, visited Company headquarters and
had access to the Data Room.
 
    By December 18, 1997, each of the six potential buyers had received a draft
of a merger agreement prepared by the Company and its legal counsel, and a
letter instructing that each bidder's "best and final" bid, indicating price per
share and key terms and conditions, as well as any comments on or changes to the
draft merger agreement, were due in January. This letter also stated that final
bids should not be conditioned on financing or further due diligence.
 
    On January 7 and 8, 1998, the Company received written offers to purchase
the Company, together with written revisions to the draft merger agreement, from
three of the six second-round bidders. The remaining three second-round bidders
did not submit offers to purchase the Company.
 
    A special meeting of the Board of Directors was held on January 9, 1998, at
which the Board reviewed the three written offers with the Company's executive
management and its legal and financial advisors. Following this review, the
Board determined that the proposal from BRS, in which each share of MEDIQ Stock
would be converted into $13.50 cash plus 0.1 of a share of Series A Preferred
Stock, was economically and structurally superior to the other two offers. In
particular, the BRS proposal represented
 
                                       28
<PAGE>
the highest value per share of MEDIQ Stock and, in addition, the cash portion of
the BRS proposal alone was higher than the total value of either of the other
two offers. Furthermore, the BRS proposal was not contingent upon the completion
of further due diligence.
 
    The BRS proposal contemplated, among other things, (i) that the Merger would
qualify for recapitalization treatment for financial reporting purposes, which
BRS proposed to achieve by requiring the Rotko Entities and certain key
executives of the Company, including Messrs. Carroll and Kaplan, to acquire an
equity interest in the Surviving Corporation, (ii) that, in satisfaction of the
foregoing requirement as it related to the Rotko Entities, the Rotko Entities
would be required to convert or exchange, prior to the Merger, between one
million and two million shares of their MEDIQ Preferred Stock into or for stock
of the Surviving Corporation, representing an equity interest of between 11.8%
and 23.6% in the Surviving Corporation, (iii) that, with respect to the other
shares of MEDIQ Stock owned by the Rotko Entities, the Rotko Entities would
receive the same consideration in the Merger as the other stockholders, (iv) the
agreement of the Rotko Entities to vote in favor of the transaction and provide
MQ with an option to purchase, under certain circumstances, all of the shares of
MEDIQ Stock owned by them, (v) the receipt by MQ for use in the Merger of
financing that, at that time, was described in draft commitment letters from
MQ's lenders which MQ indicated would be executed prior to the execution of the
merger agreement, and (vi) significant restrictions on the Board's ability to
terminate the merger agreement in the event of a superior proposal.
 
    The second highest bidder, among other things, (i) offered an aggregate
price lower than the cash portion of the BRS proposal, (ii) also required the
Rotko Entities and management to acquire an equity interest in the Surviving
Corporation, (iii) sought to conduct additional due diligence and (iv) failed to
assure the Company that it would have committed financing by the time of the
execution of a definitive merger agreement. The proposal submitted by the third
bidder offered a price lower than the cash portion of the BRS proposal and lower
than the aggregate price offered by the second highest bidder. The third
bidder's proposal also included, among other terms (i) elimination of the
Company's ability to terminate the merger agreement in the event of a higher
offer, (ii) a termination right in favor of the bidder in the event of a
material adverse change in the Company's prospects, and (iii) a relatively weak
representation and warranty from the third bidder in respect of its financing.
The Board, after conferring with executive management and the Company's legal
and financial advisors, determined, principally because of the lower bid price,
that it was not desirable for the Company to continue discussions with the third
bidder at that time.
 
   
    The Board also discussed the fact that the BRS proposal was conditioned on
the Stock Option Agreement, the Rollover Agreement, the Stockholder Agreements
and an equity investment in the Surviving Corporation by certain members of
management. The Board noted that Mark Levitan, a director since 1989, had no
interest in any proposed transaction with BRS different from that of the
Company's stockholders generally. The Board also considered the fact that, of
its members, (i) Messrs. Rotko and Shipon are, with their families,
beneficiaries of the Rotko Trust, (ii) Mr. Carroll would receive a success fee
if the Company were sold and, as president of the Company, would be likely to
invest in the Surviving Corporation, (iii) Mr. Sandler would receive a success
fee if the Company were sold, (iv) Messrs. Bonovitz and Miller had from time to
time acted as professional advisors to the Rotko family, and (v) each of the
foregoing individuals possessed interests potentially different from, or in
addition to, those of the Company's stockholders generally. Accordingly, after
further discussion, the Board asked Mr. Levitan to serve as a Special Committee
and evaluate independently the fairness of the proposed transactions.
    
 
    The Company's legal counsel then reviewed the function of the Special
Committee with the Board which, after discussion with counsel, agreed that the
Board would require the Special Committee's approval of the transactions
proposed by BRS. The Special Committee was also advised that it should consider
engaging separate counsel, to be independently selected by the Special
Committee, to assist it in reviewing the BRS proposal. The Special Committee
subsequently engaged the firm of Cozen and O'Connor to serve as its counsel.
Cozen and O'Connor was selected independently by Mr. Levitan based
 
                                       29
<PAGE>
on his past experience in dealing with the firm as his counsel in a number of
matters and on the firm's general reputation and experience in corporate and
securities transactions.
 
    The Board discussed the terms proposed by BRS for the preferred stock in the
surviving corporation to be distributed to the Company's stockholders, including
its liquidation preference and dividend accrual rate, and ways in which possibly
to improve its value. The Board also reviewed the comments of BRS on the draft
merger agreement, the probability of obtaining a break-up fee should BRS or its
acquisition subsidiary default after execution of a definitive merger agreement,
factors that could delay or prevent consummation of a merger after execution of
a definitive merger agreement, and the nature of the financing proposed to be
obtained by BRS. In addition, the Board reviewed the proposed sequence of events
for the next several days, including possible responses to each of the three
final bidders.
 
    At the conclusion of the January 9, 1998 Board meeting, the Board directed
executive management, with the assistance of the Company's legal and financial
advisors, to (i) commence negotiations with BRS, (ii) ascertain whether the
second highest bidder would be willing to raise its bid, and (iii) not hold
further discussions with the third bidder at that time. The Board also
instructed executive management and the Company's legal and financial advisors
to attempt to maximize the value of the BRS proposal and limit, to the extent
possible, the contingencies that would allow BRS to terminate a merger agreement
with the Company.
 
    During the afternoon of January 9, 1998, the second highest bidder, after
being contacted by the Company's legal and financial advisors, advised that it
expected to require three to four days of further due diligence and would also
require an additional period of time to conduct "background checks" on the
Company's management. This bidder also informed the Company that it was not
willing to increase its bid. BRS and its legal counsel were then contacted. BRS
and the Company discussed a number of issues relating to its bid. After further
negotiations that evening, BRS and the Company entered into an exclusivity
agreement terminable at any time by either party and which expired in any event
on January 15, 1998.
 
    On January 10, 1998, the Company's legal counsel delivered to BRS a revised
draft merger agreement.
 
    On January 11, 1998, representatives of BRS and its legal counsel met with
the Company's general counsel, outside legal counsel and representatives of
Salomon Smith Barney. At that meeting, there were further negotiations regarding
the terms and conditions of the BRS offer. During these negotiations, BRS was
asked to increase the value of its bid. In response, BRS indicated that it would
be willing to reallocate a portion of the aggregate value of its bid from stock
in the Surviving Corporation to cash, increasing the cash portion of its bid by
$0.25 per share (from $13.50 to $13.75 per share) and decreasing by 0.025 of a
share (from 0.1 to 0.075 of a share) the number of shares of Series A Preferred
Stock of the Surviving Corporation to be received in the Merger in exchange for
one share of MEDIQ Stock. BRS also agreed to increase the dividend rate on the
Series A Preferred Stock to 13% from 12.5% and to provide for a premium in the
event such Series A Preferred Stock was redeemed prior to January 1, 2002. The
net effect of such reallocation was to increase the value of the BRS offer,
which, giving effect to the reallocation, was estimated to be approximately
$14.25 per share of MEDIQ Stock. Alternatively, BRS indicated during the
negotiations that it would be willing to pay $14.00 cash per share of MEDIQ
Stock, but in a cash-only transaction that would not provide the Company's
stockholders with an equity interest in the Surviving Corporation. BRS would
not, however, agree to an all-cash transaction at a price greater than $14.00.
The value of the cash-only alternative, taking into account the proposed terms
of the Series A Preferred Stock and its potentially limited liquidity, was
estimated to be approximately $0.25 per share less than the combined cash and
stock proposal. Accordingly, the cash-only alternative was not pursued and the
Company continued to negotiate the Merger Agreement on the basis that the Merger
Consideration would consist of $13.75 in cash and 0.075 of a share of Series A
Preferred Stock. The parties also resolved most of the other significant issues
with respect to the terms of the Merger Agreement. At this meeting, BRS
reiterated that its offer remained subject to its reaching a satisfactory
arrangement with the Rotko Entities
 
                                       30
<PAGE>
and management in respect of their respective investments in the Surviving
Corporation, and in respect of the Stock Option Agreement, the Rollover
Agreement and the Stockholder Agreements.
 
    On January 11, 1998, the Company's legal counsel discussed with the Special
Committee and its counsel the terms of the BRS proposal, including those aspects
that related to the arrangements among BRS, the Rotko Entities and management.
During the period from January 12 through 14, 1998, the Company's legal counsel
and counsel to the Special Committee held a number of telephonic discussions in
respect of the proposed transactions.
 
    At a special meeting of the Board of Directors held on January 11, 1998, the
Board was advised of the progress of the negotiations with BRS and of the result
of discussions with the second highest bidder. Mr. Bonovitz, a director of the
Company and partner in the law firm of Duane, Morris & Heckscher LLP, counsel to
the Rotko Entities, also reported on discussions he had with counsel to BRS
regarding the general form of the proposed arrangements between BRS and the
Rotko Entities. Mr. Carroll also reported that he had engaged in general
discussions with BRS in respect of the terms of management's investment in the
Surviving Corporation and was awaiting a more specific proposal. At the
conclusion of the meeting, the Board directed the Company's executive
management, with the assistance of its advisors, to seek to finalize the merger
agreement with BRS on the terms described to the Board, and acknowledged that
management and representatives of the Rotko Entities should begin to negotiate
with BRS the arrangements requested by BRS. The Board then scheduled another
special meeting for the following evening.
 
    On January 12, 1998, the Company and its advisors continued to negotiate the
terms of the Merger Agreement with BRS and its representatives, while Mr. Rotko,
independently represented by Mr. Bonovitz and the firm of Duane, Morris &
Heckscher LLP, on behalf of the Rotko Entities, separately negotiated with BRS
the terms of the Stockholder Agreements, the Stock Option Agreement and the
Rollover Agreement. During these negotiations, the advisors to the Rotko
Entities advised BRS that the Rotko Entities would agree to invest one million
shares of MEDIQ Preferred Stock owned by them, representing the minimum amount
sought by BRS in its initial proposal of January 8, in securities of the
Surviving Corporation.
 
   
    Separately, Mr. Carroll, on behalf of himself and certain members of
management, negotiated with BRS an understanding as to the basic terms governing
management's participation in the Surviving Corporation, under which management
would (i) use the after-tax cash proceeds from approximately $9.5 million in
value received in respect of the Option Consideration paid for options to
acquire 1,000,000 shares of MEDIQ Common Stock to purchase approximately 6.1% of
the Surviving Corporation Common Stock, approximately 2.6% of the Series A
Preferred Stock, approximately 1.9% of the Series B Preferred Stock and
approximately 3.5% of the Series C Preferred Stock pursuant to the Management
Investment and (ii) receive the opportunity to purchase or receive options to
acquire additional shares of the Surviving Corporation Common Stock, all at the
same price at which BRS and the other investors would acquire securities of the
same class and/or series pursuant to the Equity Contribution.
    
 
    On the evening of January 12, 1998, the Board held a special meeting at
which the Board reviewed with executive management and the Company's legal and
financial advisors the results of the day's negotiations and certain issues
remaining to be resolved, including the status of the commitments for the
financing required by BRS, the status of the discussions between executive
management and BRS with respect to management's investment in the Surviving
Corporation and the status of the discussions between BRS and the Rotko
Entities. After a discussion, the Board authorized executive management, with
the assistance of the Company's advisors, to seek to finalize the draft merger
agreement on the terms discussed with the Board.
 
    Negotiations in respect of the final terms of the Merger Agreement, the
Stock Option Agreement, the Rollover Agreement, the Stockholder Agreements and
the arrangements with management continued on January 13, 1998 and concluded on
January 14, 1998.
 
                                       31
<PAGE>
    On January 14, 1998, the Special Committee and its legal counsel met with
Mr. Carroll and the Company's legal and financial advisors and discussed in
detail the course of the negotiations with BRS and the proposed treatment of the
Rotko Entities and Management Stockholders in the Merger. In the course of that
discussion, the Special Committee compared the proposed treatment of the
interests of the Rotko Entities and the Management Stockholders to the proposed
treatment of the interests of the Company's other stockholders. The Special
Committee discussed with its counsel and the Company's legal and financial
advisors the fact that other than in respect of the Rolled Shares, the shares of
MEDIQ Stock owned by the Rotko Entities would receive the same consideration in
the Merger as the shares of MEDIQ Stock owned by the Company's other
stockholders. The Special Committee also discussed with its counsel and the
Company's advisors the fact that the Series A Preferred Stock was senior to the
Series B Preferred Stock in respect of dividends, repurchase rights and
liquidation preference, and that the Series B Preferred Stock, unlike the Series
A Preferred Stock, would not possess optional or mandatory redemption features.
The Special Committee also discussed with its counsel and the Company's advisors
the fact that the Rolled Shares to be converted or exchanged by the Rotko
Entities into Surviving Corporation Common Stock and Series B Preferred Stock,
as well as all purchases of securities of the Surviving Corporation by the
Management Stockholders pursuant to the Management Investment and the other
terms of their arrangements with BRS, would be made at the same prices at which
the Investors would acquire securities of the same class and/or series pursuant
to the Equity Contribution, and that the conversion or exchange of the Rolled
Shares would not cause the Rotko Entities to recognize any taxable income in
respect of the Rolled Shares.
 
    After Mr. Carroll and the Company's legal and financial advisors were
excused from the meeting, the Special Committee and its counsel reviewed the
various aspects of the transaction, the results of the various negotiations with
BRS and the treatment proposed to be received by the Rotko Entities, the
Management Stockholders and the Company's other stockholders in the Merger.
 
    On the evening of January 14, 1998, the Board held a special meeting,
attended by all Board members, executive management, the Company's legal and
financial advisors and counsel to the Special Committee. The Board reviewed with
the Company's advisors the terms of the Merger Agreement and the other
agreements and arrangements contemplated thereby and reviewed the structure of
the Merger. In addition, counsel confirmed for the Board that BRS had stated
that it would not enter into the Merger Agreement unless, contemporaneously with
its execution and delivery, the Rotko Entities entered into the Stock Option
Agreement, the Rollover Agreement and the Stockholder Agreements.
 
    At the meeting, the Board also discussed, among other things, the agreements
and other arrangements among the Rotko Entities, the Management Stockholders and
BRS. In respect of the Stock Option Agreement, the Board discussed the fact that
the exercise of the Rotko Option could, under certain circumstances, allow BRS
to impede a third party bid for the Company. In reviewing the Stock Option
Agreement, the Board also noted that the Stock Option Agreement was a
requirement of the BRS bid and that, without it, the Company's stockholders
would not be able to receive the Merger Consideration. The Board also discussed
the terms on which the Rotko Entities and the Management Stockholders would
acquire their equity interests in the Surviving Corporation, and noted that such
persons would be acquiring their equity interests at the same prices at which
the Investors would acquire securities of the same class and/or series pursuant
to the Equity Contribution.
 
   
    Salomon Smith Barney then reviewed with the Board (including the Special
Committee) the financial analyses it performed in connection with its evaluation
of the Merger Consideration from a financial point of view. (See "--Opinion of
the Company's Financial Advisor.") The Board and counsel to each of the Company
and the Special Committee discussed with Salomon Smith Barney such financial
analysis and the underlying methodologies and assumptions utilized for purposes
of such analysis. Salomon Smith Barney then rendered its oral opinion (which
opinion was subsequently confirmed by delivery of a written opinion dated
January 14, 1998) to the effect that, as of the date of such opinion and based
upon and subject to certain matters stated therein, the Merger Consideration was
fair, from a financial point of view, to the
    
 
                                       32
<PAGE>
holders of MEDIQ Shares (other than the Rotko Entities and the Management
Stockholders, as to which Salomon Smith Barney was not asked to opine). See
"--Opinion of the Company's Financial Advisor."
 
    The Special Committee then reported to the Board that the Special Committee,
after reviewing the Merger Agreement, the Stock Option Agreement, the Rollover
Agreement, the Stockholder Agreements and the proposed arrangements between the
Management Stockholders and BRS, conferring with its counsel, and considering
the presentations of the Company's legal and financial advisors, approved the
Merger and the Merger Agreement, the Stock Option Agreement, the Rollover
Agreement, the Stockholder Agreements and the transactions and agreements
contemplated thereby and recommended that the Board approve the same.
 
    Thereafter, the Board voted unanimously to approve the Merger and the Merger
Agreement, the Stock Option Agreement, the Rollover Agreement, the Stockholder
Agreements and the transactions and agreements contemplated thereby and to
recommend them for approval by the Company's stockholders.
 
RECOMMENDATION OF THE SPECIAL COMMITTEE AND THE BOARD OF DIRECTORS; REASONS FOR
  THE MERGER
 
    At its meeting on January 14, 1998, the Board and the Special Committee each
unanimously determined, among other things, that the transactions contemplated
by the Merger Agreement, including the Merger and the execution and delivery of
the Stock Option Agreement, the Rollover Agreement and the Stockholder
Agreements among BRS and the Rotko Entities, and the transactions and agreements
contemplated thereby, taken together, are fair to, and in the best interests of,
the stockholders of the Company. The Special Committee and all of the members of
the Board recommend that holders of MEDIQ Stock vote FOR the Merger.
 
    Other than the recommendations of the Special Committee and the Board of
Directors that the Company's stockholders vote for the Merger, none of BRS, MQ,
the Rotko Entities, the Management Stockholders or any of the persons or
entities set forth on Schedule I hereto has made any recommendation with respect
to the Merger or any transaction or agreement contemplated thereby.
 
    The decisions of the Board and the Special Committee to approve the
Company's execution of the Merger Agreement were based, in large part, upon
balancing the risks and benefits of the Merger against the risks and benefits of
the other strategic alternatives available to the Company. After reviewing the
terms and conditions of the Merger Agreement and the transactions contemplated
thereby with their respective legal counsel and the Company's financial advisor,
the Board and the Special Committee deemed the Merger to be the alternative that
would be fair to, and in the best interests of, the stockholders of the Company.
See "-- Background of the Merger."
 
   
    In the course of reaching the decision to approve the Merger Agreement and
the Merger, during a series of meetings and special meetings that began in
November 1997 and concluded with the special meeting held on January 14, 1998,
each of the Board and the Special Committee consulted with executive management,
their respective legal counsel and the Company's financial advisor and
considered a number of factors, including, among others, the following:
    
 
    - that BRS offered the greatest aggregate consideration for each share of
      MEDIQ Stock offered in the auction process and that the $13.75 cash
      portion of the Merger Consideration exceeded the aggregate value offered
      by the next highest bidder (which had been given the opportunity to
      increase its bid but declined);
 
   
    - that the $13.75 per share cash portion of the Merger Consideration
      represents a premium of approximately 26% over the closing price of
      $10.9375 per share of the MEDIQ Common Stock on January 13, 1998 and
      approximately 20% over the closing price of $11.50 per share of the MEDIQ
      Preferred Stock on December 16, 1997, the last day MEDIQ Preferred Stock
      was traded before public announcement of the execution of the Merger
      Agreement (the closing price of MEDIQ Common Stock on such date was
      $11.56), and approximately 62% over the closing price of $8.50
    
 
                                       33
<PAGE>
      per share of the MEDIQ Common Stock and approximately 67% over the closing
      price of $8.25 per share of the MEDIQ Preferred Stock on October 29, 1997,
      the last trading day prior to the public announcement that the Company was
      evaluating strategic alternatives and had engaged Salomon Smith Barney to
      assist in that process;
 
    - that the BRS offer was substantially greater than any offer received in
      connection with the process conducted in 1995;
 
    - that, although the obligation of MQ to consummate the Merger is subject
      to, among other things, a funding condition, BRS had delivered to the
      Company commitments from its lenders for the entire amount of the debt
      financing needed to consummate the Merger transaction;
 
    - the alternatives available to the Rotko Entities as the Company's majority
      stockholders, including the possibility that they could sell their control
      position without necessarily sharing any control premium with the
      Company's other stockholders;
 
    - that the Special Committee and the Board agreed to the Merger only after a
      substantial number of potential buyers had been contacted over an extended
      period of time in a lengthy auction process designed to elicit third party
      proposals to acquire the Company and enhance stockholder value;
 
    - that the auction process, which began in October 1997, was conducted in
      what the Board and the Special Committee believed to be an evenhanded
      manner and that third parties interested in the Company had been afforded
      the opportunity to submit a proposal had they wished to do so and had been
      given access to senior management and substantial amounts of information
      to assist in formulating a proposal;
 
    - the opinion of Salomon Smith Barney to the effect that, as of the date of
      such opinion and based upon and subject to certain matters stated therein,
      the Merger Consideration was fair, from a financial point of view, to the
      holders of MEDIQ Shares (other than the Rotko Entities and the Management
      Stockholders, as to which Salomon Smith Barney was not asked to opine);
 
    - that the Rotko Entities were willing to agree to vote their shares of
      MEDIQ Stock in favor of the Merger and to enter into the Stock Option
      Agreement;
 
   
    - that the Company may, subject to the provisions set forth in the Merger
      Agreement, terminate the Merger Agreement in order to pursue a superior
      proposal if the Board of Directors determines that doing so is required by
      its fiduciary duty to the stockholders of the Company; however, the Board
      and the Special Committee recognized that (i) certain terms of the Merger
      Agreement limit the ability of the Company to consider and act upon
      competing bids in certain situations and (ii) the existence of the
      Stockholder Agreements and Stock Option Agreement may have the effect of
      discouraging persons from making or consummating competing bids;
    
 
    - that the amounts of the break-up fee and expense reimbursement under the
      Merger Agreement were reasonable in the judgment of the Special Committee
      and the Board in light of the value of the Merger Consideration to the
      Company's stockholders;
 
   
    - the terms of the Series A Preferred Stock and the market and other risks
      associated with such securities and the fact that the holders of Series A
      Preferred Stock, unlike the holders of the Surviving Corporation Common
      Stock, will not participate in increases in the residual equity value of
      the Company;
    
 
                                       34
<PAGE>
   
    - the presently favorable environment for merger transactions in the United
      States capital markets, which market condition is subject to change;
    
 
    - that BRS had agreed to provide the Company with satisfactory financial
      assurances regarding the performance by MQ of its obligations under the
      Merger Agreement;
 
    - that the Surviving Corporation agreed to honor the employment agreements
      of the Management Stockholders, who will therefore be able to continue the
      pursuit of their strategic view of the future of the Company; and
 
    - the Special Committee's and the Board's belief that, in view of the
      foregoing considerations, the Merger and Merger Agreement and the
      transactions contemplated thereby are fair to, and in the best interests
      of, the Company's stockholders.
 
    The foregoing discussion of the information and factors considered and given
weight by the Special Committee and the Board is not intended to be exhaustive.
In view of the variety of factors considered in connection with their evaluation
of the Merger, the Special Committee and the Board did not find it practicable
to, and did not, quantify or otherwise assign relative weights to the specific
factors considered in reaching their determinations. In addition, the Special
Committee and individual members of the Board may have given different weight to
different factors.
 
    The Special Committee and the Board of Directors evaluated the factors
described above in light of their knowledge of the business and operations of
the Company, and their business judgment, and concluded that the Merger and
Merger Agreement and the transactions contemplated thereby are fair to, and in
the best interests of, the Company and its stockholders.
 
    The Special Committee and the Board of Directors believe that the decision
to enter into the Merger is procedurally fair because: (i) management, with the
assistance of the Company's advisors, conducted what they believed to be a
thorough auction process; (ii) the Special Committee was disinterested and was
appointed to represent the interests of the Company's stockholders; (iii) the
Special Committee retained and was advised by Cozen and O'Connor, counsel
separate from counsel for the Company; and (iv) the Board obtained an opinion
concerning the fairness, from a financial point of view, of the Merger
Consideration to be received by the Company's stockholders in the Merger. In
light of these approvals and factors, the Special Committee and the Board of
Directors did not find it necessary to provide for the approval of the Merger
Agreement by the affirmative vote of at least a majority of the unaffiliated
stockholders of the Company.
 
PURPOSES AND REASONS OF BRS AND MQ FOR THE MERGER
 
    The purposes of the Merger are to enable BRS through MQ to make an
investment in, and obtain a controlling interest in, the Company, and to enable
existing stockholders of the Company to realize a substantial premium on the
shares of MEDIQ Stock owned by them. MQ was formed by BRS for the purpose of
engaging in such transactions. MQ elected to proceed with the Merger for the
same purpose that motivated BRS.
 
POSITION OF BRS AND MQ AS TO FAIRNESS OF THE MERGER
 
    BRS and MQ have considered (i) the historical market prices for the MEDIQ
Shares, including (x) the closing price on January 14, 1998, the last day MEDIQ
Common Stock traded before public announcement of the execution of the Merger
Agreement, as reported on the AMEX, of $11.00 per share and the closing price on
December 16, 1997, the last day MEDIQ Preferred Stock traded before public
announcement of the Merger Agreement, as reported on the AMEX, of $11.50 (the
closing price of MEDIQ Common Stock on such date was $11.56), and (y) the
closing price of $8.50 per share of the MEDIQ Common Stock and $8.25 per share
of the MEDIQ Preferred Stock on October 29, 1997, the last trading day prior to
the public announcement that the Company was evaluating strategic alternatives,
(ii) the premium the Merger Consideration represented in relation to the
historical market prices for the
 
                                       35
<PAGE>
   
MEDIQ Shares, (iii) the fact that the Company has advised BRS and MQ that its
offer provided holders of the MEDIQ Shares aggregate consideration in excess of
that offered by any of the other participants in the sale process and that the
$13.75 cash portion of the Merger Consideration exceeded the aggregate value
offered by any other bidder, (iv) the extent of the sale process described in
"--Background of the Merger," (v) the establishment of the Special Committee,
(vi) the unanimous recommendation of the Special Committee and the Board of the
Directors, (vii) the agreement of the Rotko Entities to vote their shares of
MEDIQ Stock in favor of the Merger, (viii) that the Board had received the
written opinion of its independent financial advisor (see "--Opinion of the
Company's Financial Advisor"), (ix) the arm's length nature of the negotiations
between BRS and MQ, on the one hand, and the Company, on the other, and (x) the
other analyses of and factors examined by the Special Committee and the Board
(described in detail in "--Recommendation of the Special Committee and the Board
of Directors; Reasons for the Merger"). BRS and MQ believe these analyses and
factors provide a reasonable basis for them to believe, as they do, that the
Merger is fair to the stockholders of the Company. This belief should not,
however, be construed as a recommendation to the Company's stockholders by BRS
or MQ to vote to approve the Merger or the Merger Agreement. Neither BRS nor MQ
has undertaken any formal evaluation of the fairness of the Merger to the
stockholders of the Company and neither of them has assigned specific relative
weights to the factors considered by them. BRS and MQ did not consider the net
book value or liquidation value of the Company.
    
 
   
PURPOSES AND REASONS OF THE ROTKO ENTITIES AND MESSRS. CARROLL AND KAPLAN IN
AGREEING TO THE MERGER
    
 
   
    The purposes of the Rotko Entities in agreeing to the transactions
contemplated by the Merger Agreement are to obtain substantial liquidity for
their equity investment in the Company, to facilitate the diversification of
their assets generally and to enable existing stockholders of the Company to
realize a substantial premium on the MEDIQ Shares owned by them. The purposes of
Messrs. Carroll and Kaplan in agreeing to the transactions contemplated by the
Merger Agreement are to continue the pursuit of their strategic view of the
future of the Company and to enable existing stockholders of the Company to
realize a substantial premium on the shares of MEDIQ Stock owned by them. See
"--Recommendation of the Special Committee and the Board of Directors; Reasons
for the Merger" and "--Interests of Certain Persons in the Merger."
    
 
POSITION OF THE ROTKO ENTITIES AND MESSRS. CARROLL AND KAPLAN AS TO FAIRNESS OF
  THE MERGER
 
   
    Each of the Rotko Entities and Messrs. Carroll and Kaplan believes that the
Merger is fair to the stockholders of the Company. Neither the Rotko Entities
nor Messrs. Carroll and Kaplan has undertaken any formal evaluation of the
fairness of the Merger to the stockholders of the Company and did not find it
practicable to quantify or otherwise attach relative weights to the various
factors considered by them. However, in arriving at their belief that the Merger
is fair to the stockholders of the Company, each of the Rotko Entities and
Messrs. Carroll and Kaplan considered the fact that (i) the BRS offer reflected
a multiple of the Company's estimated 1997 EBITDA of 8.0x (and estimated 1998
EBITDA of 7.4x), which was higher than was offered in the 1995 auction process
and compared favorably to selected latest 12-months EBITDA multiples ranging
from 6.4x to 7.9x in recent, comparable transactions (see "-- Opinion of the
Company's Financial Advisor--Selected Merger and Acquisition Transactions
Analysis"), (ii) the Merger Consideration represented a substantial premium over
the market price, both current and historical, of MEDIQ Stock, (iii) the Company
had conducted, with the assistance of its professional advisors, an extensive
auction, (iv) the Board had received the written opinion of its independent
financial advisor (see "--Opinion of the Company's Financial Advisor") and (v)
the Board had appointed Mr. Levitan to serve as a Special Committee to evaluate
the fairness of the proposed transaction with BRS. Finally, the Rotko Entities
and Messrs. Carroll and Kaplan considered the presently favorable environment
for merger transactions in the United States capital markets and the
availability to BRS of financing, both of which market conditions were subject
to change.
    
 
                                       36
<PAGE>
    In light of the nature of the Company's business, neither the Rotko Entities
nor Messrs. Carroll and Kaplan deemed net book value or liquidation value to be
relevant measures of the value of the Company. Accordingly, such values were not
considered.
 
    In evaluating the fairness of the transaction, the Rotko Entities and
Messrs. Carroll and Kaplan relied on the advice of the Company's advisors and
did not accord any particular weight to interim negotiating positions, including
the cash-only alternative, that were not reflected in the final offer from BRS.
 
    Each of the Rotko Entities and Messrs. Carroll and Kaplan believes that the
Merger is procedurally fair, although the approval of a majority of the
Company's stockholders other than the Rotko Entities and the Management
Stockholders is not separately required. In reaching this conclusion, the Rotko
Entities and Messrs. Carroll and Kaplan took into account a number of factors
relevant to procedural fairness as described above, including the extensive
auction process conducted by the Company, the establishment of the Special
Committee, its retention of independent legal counsel and its deliberations.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
    In considering the recommendations of the Special Committee and the Board
with respect to the Merger, stockholders should be aware that certain officers
and directors of the Company and affiliates, and associates and persons related
to the officers and directors have interests in connection with the Merger that
are different from, or in addition to, the interests of the Company's
stockholders generally. The Special Committee and the Board were aware of these
interests and considered them among the other matters described under "SPECIAL
FACTORS--Recommendation of the Board of Directors and the Special Committee;
Reasons for the Merger."
 
   
    ROTKO ENTITIES. The Rotko Entities, who as of the date hereof, collectively
were the beneficial owners of approximately 24% of the outstanding MEDIQ Common
Stock (without giving effect to the conversion of any shares of MEDIQ Preferred
Stock into shares of MEDIQ Common Stock) and 75% of the outstanding MEDIQ
Preferred Stock, may be deemed to be affiliates of the Company. The Merger
Agreement contemplates that the Rotko Entities, unlike other stockholders of the
Company, will maintain a continued interest in the Surviving Corporation Common
Stock. It is expected that immediately after the Effective Time, the Rotko
Entities will own approximately 109,781 shares or approximately 11.0% of the
outstanding Surviving Corporation Common Stock. The Rotko Entities will also be
required to acquire approximately 1,340,218 shares of the Series B Preferred
Stock. The Rotko Entities have entered into Stockholder Agreements pursuant to
which they are, subject to certain limitations, contractually bound to vote all
MEDIQ Shares owned by them in favor of the Merger. The affirmative vote of the
shares of MEDIQ Stock subject to the Stockholder Agreements will be sufficient
to approve the Merger and the Merger Agreement. See "THE STOCKHOLDER
AGREEMENTS."
    
 
   
    MQ has required, as a condition of its offer to purchase the Company, that
the Rotko Entities enter into an agreement with MQ, pursuant to which the Rotko
Entities must, immediately prior to the Merger, transfer the Rolled Shares to MQ
in exchange for securities of MQ, which at the Effective Time will be converted
into the Converted Shares. In the alternative, the Rolled Shares may be
converted into the Converted Shares in the Merger. The conversion in the Merger
of the Rolled Shares into such shares of Series B Preferred Stock and Surviving
Corporation Common Stock will not cause the Rotko Entities to recognize federal
taxable income upon such stock conversion. MQ, BRS and the Rotko Entities have
also agreed to enter into a securities rollover and holders agreement with
respect to the securities in the Surviving Corporation owned by the Rotko
Entities (the "Equity Holders Agreement"). Such Equity Holders Agreement will
contain, among other things, "drag-along" provisions requiring the Rotko
Entities to sell their securities in transactions supported by BRS, "tag-along"
rights to participate in sales of securities by BRS, and preemptive rights and
registration rights with respect to such shares, as well as certain restrictions
on their transfer. In addition, the Equity Holders Agreement will provide that
the Rotko Trust will have the right to designate one director of the Surviving
Corporation so long as the Rotko Entities collectively own 5% or more of the
Surviving Corporation Common Stock. The Rotko Trust has
    
 
                                       37
<PAGE>
   
advised the Company that it will initially designate Michael J. Rotko to serve
as a director of the Surviving Corporation. See "THE ROLLOVER AGREEMENT."
    
 
   
    SUCCESS BONUSES. The employment agreements with the Company's President and
Chief Executive Officer, Thomas E. Carroll, its Chief Financial Officer, Jay M.
Kaplan, and Michael F. Sandler, a director of the Company and its former Chief
Financial Officer, include provisions entitling those persons to bonuses,
calculated based, in the cases of Messrs. Carroll and Kaplan, upon the aggregate
purchase price paid for the Company and, in the case of Mr. Sandler, upon the
value received by the Company's stockholders upon a sale of the Company.
    
 
   
    Under the terms of his employment agreement with the Company, Mr. Carroll
will receive a one-time "success bonus" if, before June 30, 1998, a "Strategic
Transaction" (as defined in his employment agreement) occurs. The Merger
constitutes a "Strategic Transaction." Mr. Carroll's bonus payable upon a
Strategic Transaction is equal to the sum of (i) 0.25% of the aggregate purchase
price paid for the Company up to $375.0 million plus (ii) if the aggregate
purchase price paid for the Company exceeds $375.0 million, 1.5% of any purchase
price in excess of $375.0 million. For purposes of calculating the bonus, the
aggregate purchase price is based on the sum of (x) the total cash consideration
paid, plus (y) the value of any securities or other property received as
consideration, plus (z) the aggregate amount (including, without limitation,
accrued but unpaid interest and the unpaid amount of any capital leases) of any
liabilities assumed or refinanced by the purchaser in the acquisition, other
than current liabilities taken into account in computing working capital (except
for current liabilities for indebtedness for money borrowed, including accrued
but unpaid interest on capital leases). Accordingly, the Company expects to pay
a bonus to Mr. Carroll of approximately $3.9 million upon consummation of the
Merger. Mr. Carroll's employment agreement further provides that if he becomes
entitled to receive the incentive bonus referred to in the preceding sentence,
he will forfeit all rights to any stock appreciation right compensation
previously granted to him pursuant to his employment agreement. Under his
employment agreement, Mr. Carroll is also entitled to receive an additional
payment from the Company to compensate him for liabilities, if any, imposed
under Section 4999 of the Code, or any successor provision thereto.
    
 
    Under the terms of his employment agreement, Mr. Kaplan, Senior Vice
President and Chief Financial Officer of the Company, is entitled to receive a
one-time cash bonus upon the occurrence of a "Sale Event" (as defined in his
employment agreement). The Merger constitutes a "Sale Event." Mr. Kaplan's bonus
payable upon a Sale Event equals the sum of (i) 0.025% of the aggregate purchase
price paid for the Company up to $375.0 million plus (ii) if the aggregate
purchase price paid for the Company exceeds $375.0 million, 0.15% of any
purchase price in excess of $375.0 million. For purposes of calculating the
bonus, the aggregate purchase price is based on the sum of (x) the total cash
consideration paid for the Company, plus (y) the value of any securities or
other property received as consideration for the Company, plus (z) the aggregate
amount of any liabilities of the Company assumed or refinanced by the purchaser
in connection with the completion of the acquisition, other than current
liabilities taken into account in computing the working capital of the Company
(except for current liabilities for indebtedness for money borrowed, including
accrued but unpaid interest on capital leases). Accordingly, the Company expects
to pay a bonus to Mr. Kaplan of approximately $390,000 upon consummation of the
Merger.
 
    Mr. Sandler, a director of the Company, was Senior Vice President --
Finance, Treasurer and Chief Financial Officer of the Company until September
30, 1997. Under the terms of his employment agreement, Mr. Sandler is entitled
to receive a one-time bonus upon an "Event of Sale" (as defined in his
employment agreement), based on the value realized by the Company's stockholders
in the event of such a transaction, if the transaction occurs during either the
term of his employment agreement or the one-year period thereafter. The Merger
constitutes an "Event of Sale." If the Company's stockholders receive value for
their MEDIQ Shares equal to $6.50 or more per share, Mr. Sandler's bonus would
equal $.5 million, plus an additional $1,000 for each additional $.01 by which
the value received by the Company's stockholders exceeds $6.50 per MEDIQ Share.
Accordingly, the Company expects to pay a bonus to Mr. Sandler of approximately
$1.3 million upon consummation of the Merger.

    The executive officers of the Company are expected to remain in place after
the Merger and their current employment agreements will remain in effect.
 
   
    OPTIONS. Options held by officers of the Company, (including Options which
have not yet vested), will be treated in the same manner as Options held by
non-officers, as described in "THE MERGER--Option Consideration" and "--Effect
on Stock and Employee Benefit Matters." The number of Options held by Mr.
Carroll, Mr. Sandler and Mr. Kaplan are set forth in the table below.

    MANAGEMENT EQUITY INVESTMENT. The Management Stockholders are expected to
use the after-tax cash proceeds from approximately $9.5 million in value
received in respect of the Option Consideration paid for options to acquire
1,000,000 shares of MEDIQ Common Stock to purchase approximately $4.2 million of
securities of MQ, which upon consummation of the Merger will be converted into
approximately 201,549 shares (or approximately 2.6%) of the Series A Preferred
Stock, approximately 57,419 shares (or approximately 1.9%) of the Series B
Preferred Stock, approximately 103,782 shares (or approximately 3.5%) of the
Series C Preferred Stock and approximately 61,000 shares (or approximately 6.1%)
of the Surviving Corporation Common Stock. Such shares shall be acquired for a
purchase price of $10 per share, the same price per share as the securities sold
to the Investors pursuant to the Equity Contribution. See "THE MERGER--Option
Consideration." For more information regarding the ownership of securities of
the Surviving Corporation, see "SECURITY OWNERSHIP IN THE SURVIVING
CORPORATION."
    
 
   
    Immediately after the Effective Time and in connection with the Merger, it
is expected that certain persons designated by the Company will be provided the
opportunity to purchase additional shares of Surviving Corporation Common Stock
representing approximately 8.3% (on a fully diluted basis) of the Surviving
Corporation Common Stock at the same per share price as the shares of Surviving
Corporation Common Stock sold to the Investors pursuant to the Equity
Contribution. The Surviving Corporation Common Stock so acquired (the
"Management Purchase Shares") will, as to an individual employee be subject to
certain rights of the Company to repurchase such Surviving Corporation Common
Stock if, at any time during the five years after the date of such acquisition,
such employee resigns or is terminated. The amount of shares subject to the
Company's repurchase option and the price at which they may be repurchased are
subject to a variety of factors, including whether the employee is terminated
for cause or without cause and at what point over the five-year period any
resignation or termination occurs.
    
 
   
    Over a five-year period beginning on the Effective Time, it is also expected
that certain employees of the Company will be provided with the opportunity to
receive non-qualified options (the "New Options") to purchase shares of
Surviving Corporation Common Stock representing approximately 2.8% of the
outstanding Surviving Corporation Common Stock on a fully diluted basis at a
price per share equal to the price per share at which the shares of Surviving
Corporation Common Stock are sold to the Investors pursuant to the Equity
Contribution. Each year during such five-year period, such persons will have the
opportunity to acquire one-fifth of the New Options. For each year, the
opportunity to receive any New
    
 
                                       39
<PAGE>
   
Option will be subject to the Surviving Corporation's achievement of certain
financial performance conditions. In certain circumstances, such persons will
have the right to immediately receive any unissued or unvested New Options
regardless of whether certain financial performance conditions have been met.
    
 
    OTHER.  Under the terms of the Company's deferred compensation plan,
approximately $1.6 million of previously deferred employee compensation will
become payable upon consummation of the Merger to certain former members of
senior management of the Company who have previously deferred such compensation.
Deferred compensation will be paid to employees only at their election.
 
    Pursuant to the Merger Agreement, the Company is obligated, for a period of
six years after the effective time of the Merger, to indemnify directors and
officers of the Company and, subject to certain limitations, to maintain
directors' and officers' liability insurance substantially similar to that
currently in effect.
 
   
    MQ currently anticipates that BRS, or an affiliate of BRS, will enter into a
Management Agreement with MEDIQ/PRN (the "Management Agreement") at the
Effective Time. The Management Agreement will provide that BRS or such affiliate
will receive an annual management fee of $1.0 million from MEDIQ/PRN for certain
management, business and organizational strategy and merchant and investment
banking services rendered to the Company. The amount of the annual management
fee may be increased in certain circumstances based upon performance or other
criteria to be established by the Board of Directors of the Company. Such
management fees may be shared among BRS, FFT and Galen. In addition, an
affiliate of BRS, together with FFT and Galen, will receive from MEDIQ/PRN a
closing fee of approximately $6.0 million, in the aggregate, at the Effective
Time in respect of the Transactions. See "SOURCES AND AMOUNT OF FUNDS--Equity
Contribution."
    
 
ANTICIPATED ACCOUNTING TREATMENT
 
    The transaction has been structured as a merger so that stockholders of the
Company will have an opportunity to vote for or against the transaction prior to
any transfer of control and so that it can qualify and be accounted for as a
recapitalization. If the transaction is accounted for as a recapitalization, the
historical basis of the Company's assets and liabilities will not be affected by
the transaction. See "PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS."
 
FEDERAL INCOME TAX CONSEQUENCES
 
   
    The following is a general summary of the material federal income tax
consequences of the Merger to owners of MEDIQ Stock and is based upon current
provisions of the Code, existing regulations thereunder and current
administrative rulings and court decisions, all of which are subject to change.
The discussion assumes that stockholders of the Company hold their shares of
MEDIQ Stock as a capital asset within the meaning of Section 1221 of the Code -
I.E., that the shares are not being held as stock in trade, inventory, or
otherwise primarily for sale to customers in the ordinary course of a trade or
business. No attempt has been made to comment on all federal income tax
consequences of the Merger that may be relevant to particular stockholders who
are subject to special tax rules, such as dealers in securities, foreign
persons, mutual funds, insurance companies and tax-exempt entities. Furthermore,
the discussion does not address tax consequences that may apply to the Rotko
Entities, the Management Stockholders or to persons who may be considered,
applying the constructive stock ownership rules of Section 318 of the Code, to
own shares of stock of the Surviving Corporation that are held by the Rotko
Entities, BRS or other investors in MQ.
    
 
    OWNERS OF MEDIQ STOCK ARE ADVISED TO CONSULT THEIR OWN TAX ADVISORS
REGARDING THE FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER IN LIGHT OF THEIR
PERSONAL CIRCUMSTANCES AND THE CONSEQUENCES UNDER STATE, LOCAL AND FOREIGN TAX
LAWS.
 
    THE MERGER.  Owners of MEDIQ Stock will be treated as recognizing capital
gain or loss equal to the sum of (i) the cash received and (ii) the fair market
value of the Series A Preferred Stock received less the stockholder's basis in
the stock surrendered in the Merger. Such capital gain or loss will be long-term
(20%
 
                                       40
<PAGE>
or 28% rate for non-corporate taxpayers) or short-term, depending on the
stockholder's holding period for the MEDIQ Stock. A stockholder's basis for
Series A Preferred Shares received in the Merger will also equal the fair market
value of such shares at that time.
 
    DISTRIBUTIONS ON SERIES A PREFERRED STOCK.  Cash distributions on the Series
A Preferred Stock will be taxable to the holder as ordinary dividend income to
the extent that the cash amount does not exceed the Company's then current or
accumulated earnings and profits (as determined for federal income tax
purposes). To the extent that the amount of any distribution on the outstanding
Series A Preferred Stock exceeds the Company's then current or accumulated
earnings and profits (as determined for federal income tax purposes), the
distribution will be treated as a return of capital, thus reducing the holder's
adjusted tax basis in such outstanding Series A Preferred Stock. The amount of
any such excess distribution that is greater than the holder's adjusted tax
basis in the outstanding Series A Preferred Stock will be taxed as capital gain
and will be long-term capital gain (at a 20% or 28% rate for non-corporate
taxpayers, as applicable) if the holder's holding period for such outstanding
Series A Preferred Stock exceeds one year.
 
    To the extent that dividends are treated as ordinary income, dividends
received by corporate holders generally will be eligible for the 70%
dividends-received deduction under Section 243 of the Code. There are, however,
many exceptions and restrictions relating to the availability of such
dividends-received deduction, such as restrictions relating to (i) the holding
period of the stock on which the dividends are sought to be deducted, (ii)
debt-financed portfolio stock, (iii) dividends treated as "extraordinary
dividends" for purposes of Section 1059 of the Code, and (iv) taxpayers that pay
alternative minimum tax. Corporate stockholders should consult their own tax
advisor regarding the extent, if any, to which such exceptions and restrictions
may apply to their particular factual situations.
 
    Under Section 1059 of the Code, the tax basis of Series A Preferred Stock
that has been held by a corporate stockholder for two years or less is generally
reduced (but not below zero) by the non-taxed portion of an "extraordinary
dividend" for which a dividends-received deduction is allowed. To the extent
that a corporate holder's tax basis in its Series A Preferred Stock would have
been reduced below zero, such holder must generally recognize gain upon receipt
of such an "extraordinary dividend." Generally, an "extraordinary dividend" is a
dividend that (i) equals or exceeds 5% of the holder's basis in the Series A
Preferred Stock (treating all dividends having ex-dividend dates within an
85-day period as a single dividend) or (ii) exceeds 20% of the holder's adjusted
basis in the Series A Preferred Stock (treating all dividends having ex-dividend
dates within a 365-day period as a single dividend).
 
    CORPORATE STOCKHOLDERS ARE URGED TO CONSULT THEIR TAX ADVISORS WITH RESPECT
TO THE POSSIBLE APPLICATION OF SECTION 1059 OF THE CODE TO THEIR OWNERSHIP OF
PREFERRED STOCK.
 
   
    The declaration and payment of cash dividends with respect to shares of
Series A Preferred Stock will, after the Effective Time, be limited under the
terms of the financing arrangements of the Company. See "DESCRIPTION OF MEDIQ
CAPITAL STOCK FOLLOWING THE MERGER--Series A Preferred Stock--Dividends" and
"SOURCES AND AMOUNT OF FUNDS." Dividends that are not declared currently will,
under the terms of the Series A Preferred Stock, be added to the liquidation
preference of the Series A Preferred Stock unless declared and paid prior to
liquidation. The Company does not believe that, under current law, holders of
Series A Preferred Stock will be required to include any such accrued and unpaid
dividends in income until such dividends are paid in cash, and the Company does
not intend to treat any such accruing but unpaid dividends as distributions to
holders of Series A Preferred Stock under the information reporting rules.
Holders should be aware that the Internal Revenue Service could take the
position that such dividends are includible in income as they accrue prior to
the time that such dividends are declared and paid in cash.
    
 
    SERIES A PREFERRED STOCK DISCOUNT.  The Series A Preferred Stock is subject
to mandatory redemption on December 31, 2011 (the "Mandatory Redemption"). In
addition, subject to certain restrictions, the Series A Preferred Stock is
redeemable at any time or from time to time at the option of the Company at
 
                                       41
<PAGE>
specified redemption prices (the "Optional Redemption"). See "DESCRIPTION OF
MEDIQ CAPITAL STOCK FOLLOWING THE MERGER--Series A Preferred Stock--Optional
Redemption" and "-- Mandatory Redemption." In the event that the fair market
value of a share of Series A Preferred Stock is determined to be less than its
stated liquidation preference at the time of the Merger, holders of Series A
Preferred Stock may be required, pursuant to Section 305(c) of the Code, to
treat a portion of the difference between the Series A Preferred Stock's issue
price and its redemption price as constructive distributions of property
includible in income on a periodic basis as it accrues.
 
    Section 305(c) of the Code provides that the entire amount of a redemption
premium with respect to preferred stock that is subject to mandatory redemption
is treated as being distributed to the holders of such preferred stock on an
economic accrual basis over the period from issuance to the date of such
mandatory redemption. Preferred stock generally is considered to have a
redemption premium for this purpose if the price at which it must be redeemed
(the "Redemption Price") exceeds its issue price (its fair market value at the
time of issuance) by more than a DE MINIMIS amount. For this purpose, such
excess (the "Series A Preferred Stock Discount") will be treated as zero if it
is less than 1/4 of 1% of the Redemption Price multiplied by the number of
complete years from the date of issuance of the stock until the stock must be
redeemed. Series A Preferred Stock Discount is taxable as a constructive
distribution to the holder (treated as a dividend to the extent of the Company's
current and accumulated earnings and profits and otherwise subject to the
treatment described above for distributions) over the term of the preferred
stock using a constant interest rate method.
 
    Under recently issued regulations (the "Regulations"), certain optional
redemption features may also result in constructive distributions over the
period from the date of issue to the date of such optional redemption
distribution. The Company does not believe that the optional redemption rights
will result in constructive distributions to holders of Series A Preferred Stock
under these rules.
 
    SALE OR REDEMPTION OF SERIES A PREFERRED STOCK.  A redemption of shares of
Series A Preferred Stock for cash would be a taxable event. A redemption of
shares of Series A Preferred Stock for cash will generally be treated as a sale
or exchange if the holder does not own, actually or constructively within the
meaning of Section 318 of the Code, any stock of the Company other than the
redeemed Series A Preferred Stock. If a holder does own, actually or
constructively, other stock of the Company (including Series A Preferred Stock
not redeemed), a redemption of Series A Preferred Stock may, in certain
circumstances, be treated as a dividend to the extent of the Company's current
and accumulated earnings and profits (as determined for federal income tax
purposes). Such dividend treatment would not be applied if the redemption is
"not essentially equivalent to a dividend" with respect to the holder under
Section 302(b)(1) of the Code. A distribution to a holder will be "not
essentially equivalent to a dividend" if it results in a "meaningful reduction"
in the holder's stock interest in the Company. For this purpose, a redemption of
Series A Preferred Stock that results in a reduction in the proportionate
interest in the Company (taking into account any actual ownership of common
stock of the Company and any stock constructively owned) of a holder whose
relative stock interest in the Company is minimal and who exercises no control
over corporate affairs should be regarded as a meaningful reduction in the
holder's stock interest in the Company.
 
    If the redemption of the Series A Preferred Stock for cash is not treated as
a distribution taxable as a dividend, the redemption would result in capital
gain or loss equal to the difference between the amount of cash received and the
holder's adjusted tax basis in the Series A Preferred Stock redeemed, except to
the extent that the redemption price includes dividends which have been declared
by the Board of Directors of the Company prior to the redemption (such dividends
being separately taxable as described above). Similarly, upon the sale of the
Series A Preferred Stock, the difference between the sum of the amount of cash
and the fair market value of other property received and the holder's adjusted
basis in the Series A Preferred Stock would result in capital gain or loss. This
gain or loss would be long-term capital gain or loss if the holder's holding
period for the Series A Preferred Stock exceeds one year. Under current law,
capital gains recognized by corporations are taxed at a maximum rate of 35% and
the maximum rate on net capital gains in the case of individuals and other
non-corporate taxpayers is 20% for holding periods over 18 months (28% for
holding periods over one year, but not more than 18 months).
 
                                       42
<PAGE>
    If a redemption of Series A Preferred Stock is treated as a distribution
that is taxable as a dividend, the amount of the distribution will be measured
by the amount of cash received by the holder. The holder's adjusted tax basis in
the redeemed Series A Preferred Stock will be transferred to any remaining stock
holdings in the Company. If the holder does not retain any actual stock
ownership in the Company (only having a stock interest constructively), the
holder may lose such basis entirely. Under the "extraordinary dividend"
provision of Section 1059 of the Code, a corporate holder may, under certain
circumstances, be required to reduce its basis in its remaining shares of stock
of the Company (and possibly recognize gain) to the extent the holder claims the
70% dividends-received deduction with respect to the dividend. See the
discussion above under "--Distributions on Series A Preferred Stock."
 
    BACKUP WITHHOLDING.  Owners of MEDIQ Shares should be aware that the Company
will be required in certain cases to withhold and remit to the United States
Treasury 31% of amounts payable in the Merger or as dividends on Series A
Preferred Shares to any person (1) who has provided either an incorrect tax
identification number or no number at all, (2) who is subject to backup
withholding by the Internal Revenue Service for failure to report the receipt of
interest or dividend income properly, or (3) who has failed to certify to the
Company that he is not subject to backup withholding or that he is an "exempt
recipient." Backup withholding is not an additional tax, but rather may be
credited against the taxpayer's tax liability for the year.
 
OPINION OF THE COMPANY'S FINANCIAL ADVISOR
 
   
    Salomon Smith Barney was retained by the Company to act as its financial
advisor in connection with the proposed Merger. In connection with such
engagement, the Company requested that Salomon Smith Barney evaluate the
fairness, from a financial point of view, to the holders of MEDIQ Shares (other
than the Rotko Entities and the Management Stockholders, as to which Salomon
Smith Barney was not asked to opine), of the consideration to be received by
such holders in the Merger. On January 14, 1998, at meetings of the Board of
Directors of the Company and the Special Committee held to evaluate the proposed
Merger, Salomon Smith Barney delivered an oral opinion (which opinion was
subsequently confirmed by delivery of a written opinion dated January 14, 1998)
to the effect that, as of the date of such opinion and based upon and subject to
certain matters stated therein, the Merger Consideration was fair, from a
financial point of view, to the holders of MEDIQ Shares (other than the Rotko
Entities and the Management Stockholders).
    
 
    In arriving at its opinion, Salomon Smith Barney reviewed the Merger
Agreement and the terms of the Series A Preferred Stock attached as an exhibit
thereto and held discussions with certain senior officers, directors and other
representatives and advisors of the Company and certain senior officers and
other representatives and advisors of MQ concerning the business, operations and
prospects of the Company. Salomon Smith Barney examined certain publicly
available business and financial information relating to the Company as well as
certain financial forecasts and other information and data for the Company which
were provided to or otherwise discussed with Salomon Smith Barney by the
management of the Company. Salomon Smith Barney reviewed the financial terms of
the Merger as set forth in the Merger Agreement in relation to, among other
things: current and historical market prices and trading volumes of MEDIQ
Shares; the financial condition and historical and projected earnings and other
operating data of the Company; and the capitalization of the Company and MQ.
Salomon Smith Barney also considered, to the extent publicly available, the
financial terms of certain other similar transactions recently effected which
Salomon Smith Barney 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 Salomon Smith
Barney considered relevant in evaluating those of the Company. In connection
with its engagement, Salomon Smith Barney was requested to approach, and held
discussions with, third parties to solicit indications of interest in a possible
acquisition of the Company. In addition to the foregoing, Salomon Smith Barney
conducted such other analyses and examinations and considered such other
financial, economic and market criteria as Salomon Smith Barney deemed
appropriate in arriving at its opinion. Salomon Smith Barney noted that its
opinion was necessarily based upon
 
                                       43
<PAGE>
information available, and financial, stock market and other conditions and
circumstances existing and disclosed, to Salomon Smith Barney as of the date of
its opinion.
 
    In rendering its opinion, Salomon Smith Barney assumed and relied, without
independent verification, upon the accuracy and completeness of all financial
and other information and data publicly available or furnished to or otherwise
reviewed by or discussed with Salomon Smith Barney. With respect to financial
forecasts and other information and data provided to or otherwise reviewed by or
discussed with Salomon Smith Barney, the management of the Company advised
Salomon Smith Barney that such forecasts and other information and data were
reasonably prepared on bases reflecting the best currently available estimates
and judgments of the management of the Company as to the future financial
performance of the Company. Representatives of the Company also advised Salomon
Smith Barney that, in the Merger, the MEDIQ Preferred Stock would be treated as
the equivalent of the MEDIQ Common Stock into which it is convertible and,
therefore, with the consent of the Board of Directors of the Company, Salomon
Smith Barney evaluated the MEDIQ Preferred Stock as the equivalent of the MEDIQ
Common Stock for purposes of its opinion. Salomon Smith Barney assumed, with the
consent of the Board of Directors of the Company, that the Merger will be
recorded as a recapitalization for financial reporting purposes. Salomon Smith
Barney did not express any opinion as to what the value of the Series A
Preferred Stock will be when issued pursuant to the Merger or the price at which
the Series A Preferred Stock will trade or otherwise be transferable subsequent
to the Merger. Salomon Smith Barney did not make and was not provided with an
independent evaluation or appraisal of the assets or liabilities (contingent or
otherwise) of the Company nor did Salomon Smith Barney make any physical
inspection of the properties or assets of the Company. Although Salomon Smith
Barney evaluated the Merger Consideration from a financial point of view,
Salomon Smith Barney was not asked to and did not recommend the specific
consideration payable in the Merger, which was determined through negotiation
between the Company and MQ. No other limitations were imposed by the Company on
Salomon Smith Barney with respect to the investigations made or procedures
followed by Salomon Smith Barney in rendering its opinion.
 
    THE FULL TEXT OF THE WRITTEN OPINION OF SALOMON SMITH BARNEY DATED JANUARY
14, 1998, WHICH SETS FORTH THE ASSUMPTIONS MADE, MATTERS CONSIDERED AND
LIMITATIONS ON THE REVIEW UNDERTAKEN, IS ATTACHED HERETO AS ANNEX B AND IS
INCORPORATED HEREIN BY REFERENCE. HOLDERS OF MEDIQ SHARES ARE URGED TO READ THIS
OPINION CAREFULLY IN ITS ENTIRETY. THE OPINION OF SALOMON SMITH BARNEY IS
DIRECTED TO THE BOARD OF DIRECTORS OF THE COMPANY AND RELATES ONLY TO THE
FAIRNESS OF THE MERGER CONSIDERATION FROM A FINANCIAL POINT OF VIEW, DOES NOT
ADDRESS ANY OTHER ASPECT OF THE MERGER OR RELATED TRANSACTIONS AND DOES NOT
CONSTITUTE A RECOMMENDATION TO ANY STOCKHOLDER AS TO HOW SUCH STOCKHOLDER SHOULD
VOTE AT THE MEDIQ SPECIAL MEETING. THE SUMMARY OF THE OPINION OF SALOMON SMITH
BARNEY SET FORTH IN THIS PROXY STATEMENT/PROSPECTUS SETS FORTH THE MATERIAL
ELEMENTS OF SUCH OPINION.
 
    In preparing its opinion, Salomon Smith Barney performed a variety of
financial and comparative analyses, including those described below, and
provided the Company's Board and the Special Committee with a written
presentation with respect to such analyses. A copy of Salomon Smith Barney's
written presentation has been filed as an exhibit to the Schedule 13E-3 filed
with the Commission with respect to the Merger and will be available for
inspection and copying at the principal executive offices of the Company during
regular business hours by any interested stockholder or representatives of such
stockholder who have been designated as such in writing and may be inspected and
copied and obtained by mail from the Commission in the manner specified in
"AVAILABLE INFORMATION." The summary of such analyses does not purport to be a
complete description of the analyses underlying Salomon Smith Barney's opinion.
The preparation of a fairness opinion is a complex analytic process involving
various determinations as to the most appropriate and relevant methods of
financial analyses and the application of those methods to the particular
circumstances and, therefore, such an opinion is not readily susceptible to
summary description. Accordingly, Salomon Smith Barney believes that its
analyses must be considered as a whole and that selecting portions of its
analyses and factors, without considering all analyses and factors, could create
a misleading or incomplete view of the processes underlying such analyses and
opinion. In its analyses, Salomon Smith Barney made numerous assumptions with
respect to the Company, MQ, industry
 
                                       44
<PAGE>
performance, general business, economic, market and financial conditions and
other matters, many of which are beyond the control of the Company and MQ, such
as, among other things, the impact of competition on the business of the Company
and the medical equipment rental industry generally, industry growth, the
financing capability of MQ and its affiliates and the absence of any material
adverse change in the financial condition and prospects of the Company or the
medical equipment rental industry or in the financial markets in general. The
estimates contained in such analyses and the valuation ranges resulting from any
particular analysis are not necessarily indicative of actual values or
predictive of future results or values, which may be significantly more or less
favorable than those suggested by such analyses. In addition, analyses relating
to the value of businesses or securities do not purport to be appraisals or to
reflect the prices at which businesses or securities actually may be sold.
Accordingly, such analyses and estimates are inherently subject to substantial
uncertainty. Salomon Smith Barney's opinion and analyses were only one of many
factors considered by the Board of Directors of the Company and the Special
Committee in their evaluation of the Merger and should not be viewed as
determinative of the views of the Board of Directors, the Special Committee or
management of the Company with respect to the Merger Consideration or the
proposed Merger.
 
    SELECTED COMPANY ANALYSIS.  Using publicly available information, Salomon
Smith Barney analyzed, among other things, the market values and trading
multiples of the following selected publicly traded companies in the medical
equipment rental industry: Cohr Inc.; DVI Inc.; Hillenbrand Industries, Inc.;
Kinetic Concepts, Inc.; and Leasing Solutions Inc. (collectively, the "Selected
Companies"). Salomon Smith Barney compared market values as multiples of, among
other things, estimated calendar 1998 and 1999 earnings per share ("EPS"), and
adjusted market values (fully diluted market value, plus total debt outstanding,
less cash) as multiples of, among other things, latest 12 months revenues and
earnings before interest, taxes, depreciation and amortization ("EBITDA"). EPS
multiples for the Selected Companies were based on estimates of selected
investment banking firms and EPS multiples for the Company were based on
internal estimates of the management of the Company. All multiples were based on
closing stock prices as of January 12, 1998. Applying a range of selected
multiples for the Selected Companies of estimated calendar 1998 and 1999 EPS and
latest 12 months revenue and EBITDA of 14.0x to 18.0x, 11.5x to 14.5x, 2.2x to
2.8x and 7.7x to 9.3x, respectively, to corresponding financial data for the
Company resulted in an equity reference range for MEDIQ of approximately $9.86
to $12.93 per share, as compared to the Merger Consideration of approximately
$14.25 per share.
 
    SELECTED MERGER AND ACQUISITION TRANSACTIONS ANALYSIS.  Using publicly
available information, Salomon Smith Barney analyzed, among other things, the
implied transaction value multiples paid in the following selected transactions
in the medical equipment rental industry (acquiror/target): J.W. Childs Equity
Partners LP/Universal Hospital Services, Inc.; Richard C. Blum & Associates LP
and Fremont Partners LP/ Kinetic Concepts, Inc.; Universal Hospital Services,
Inc./Biomedical Equipment Rental & Sales, Inc.; MEDIQ/KCI Therapeutic Services,
Inc.; and MEDIQ/ATI Medical Inc. (collectively, the "Selected Transactions").
Salomon Smith Barney compared, among other things, transaction values as
multiples of latest 12 months revenues, EBITDA and earnings before interest and
taxes ("EBIT"). All multiples for the Selected Transactions were based on
information available at the time of announcement of the transaction. Applying a
range of selected multiples (excluding outliers) for the Selected Transactions
of latest 12 months revenues, EBITDA and EBIT of 2.2x to 2.8x, 6.4x to 7.9x and
13.2x to 16.2x, respectively, to corresponding financial data for the Company
resulted in an equity reference range for the Company of approximately $10.32 to
$13.42 per share, as compared to the Merger Consideration of approximately
$14.25 per share.
 
    No company, transaction or business used in the "Selected Company Analysis"
or "Selected Merger and Acquisition Transactions Analysis" as a comparison is
identical to the Company, MQ or the Merger. Accordingly, an analysis of the
results of the foregoing is not entirely mathematical; rather, it involves
complex considerations and judgments concerning differences in financial and
operating characteristics and other factors that could affect the acquisition,
public trading or other values of the Selected
 
                                       45
<PAGE>
Companies, Selected Transactions or the business segment, company or transaction
to which they are being compared.
 
    DISCOUNTED CASH FLOW ANALYSIS.  Salomon Smith Barney performed a discounted
cash flow analysis of the projected free cash flows of the Company for fiscal
years 1998 through 2002, based on internal estimates of the management of the
Company prepared under two scenarios, a base case ("Case I") and a growth case
("Case II"). The stand-alone discounted cash flow analysis of the Company was
determined by (i) adding (x) the present value of projected free cash flows over
the five-year period from 1998 to 2002 and (y) the present value of the
Company's estimated terminal value in year 2002 and (ii) subtracting the current
net debt of the Company. The range of estimated terminal values for the Company
at the end of the five-year period was calculated by applying terminal value
multiples ranging from 7.0x to 8.0x to the Company's projected 2002 EBITDA. The
cash flows and terminal values of the Company were discounted to present value
using discount rates ranging from 10.5% to 12.5% (Case I) and 14.5% to 16.5%
(Case II). Utilizing such terminal values and discount rates, these analyses
resulted in equity reference ranges for the Company of approximately $13.87 to
$17.60 per share (Case I) and $14.56 to $18.43 per share (Case II), as compared
to the equity value implied by the Merger Consideration of approximately $14.25
per share.
 
    PREMIUM ANALYSIS.  Salomon Smith Barney compared the premiums paid in the
Selected Transactions with the implied premium payable in the Merger. Applying a
range of selected premiums for the Selected Transactions of 25.0% to 40.0% to
the closing stock price of MEDIQ Common Stock on October 29, 1997 (the date on
which the Company publicly announced that it was exploring strategic
alternatives) resulted in an equity reference range for the Company of
approximately $10.63 to $11.90 per share, as compared to the Merger
Consideration of approximately $14.25 per share. The trading range of MEDIQ
Common Stock over the 52-week period prior to public announcement of the Merger
was between $6.31 and $11.88 per share.
 
    ABSOLUTE ACCRETION/DILUTION ANALYSIS.  Salomon Smith Barney analyzed the
ranges of prices that could potentially be payable by a strategic buyer of MEDIQ
Shares without the transaction having a dilutive effect on such buyer's EPS,
based on internal estimates of the management of the Company as to, among other
things, the pro forma combined company and the cost savings and other potential
synergies that could result from a transaction with a strategic buyer. For
purposes of such analysis, Salomon Smith Barney assumed, among other things,
transaction borrowing costs for such buyer consistent with a high quality credit
borrower. This analysis indicated that, at purchase prices in excess of $13.00
per share, the acquisition of the Company by a strategic buyer could be dilutive
to such buyer's EPS.
 
    SERIES A PREFERRED STOCK VALUATION ANALYSIS.  Salomon Smith Barney analyzed
the Series A Preferred Stock issuable in the Merger, based on Case I and Case II
estimates and on internal estimates of the management of the Company and
representatives of MQ as to, among other things, the debt-to-latest 12 months
EBITDA ratios of the pro forma combined company. The potential yield on the
Series A Preferred Stock was estimated by comparing the terms of the Series A
Preferred Stock with those of senior subordinated debt securities issued by
entities with debt-to-EBITDA levels comparable to those of the pro forma
combined entity. Risk adjustments were made for, among other things, seniority,
maturity, interest rates and liquidity. This analysis resulted in a present
value estimate for the Series A Preferred Stock of approximately $.50 per 0.075
of a share.
 
   
    OTHER FACTORS AND COMPARATIVE ANALYSES.  In rendering its opinion, Salomon
Smith Barney considered certain other factors and conducted certain other
comparative analyses, including, among other things, a review of (i) indications
of interest received from third parties other than MQ; (ii) the Company's
historical and projected financial results, (iii) the history of trading prices
and volume for MEDIQ Shares and the relationship between movements of such
shares, movements in the common stock of the Selected Companies and movements in
the S&P Industrial 500 Index, (iv) the liquidation, voting, conversion and
dividend features of the MEDIQ Preferred Stock and the Series A Preferred Stock,
(v) the potential rates of return of an equity investment in the pro forma
combined company, and (vi) the break-up fees in selected transactions with
transaction values of between $500 million and $750 million.

    Pursuant to the terms of Salomon Smith Barney's engagement, the Company has
agreed to pay Salomon Smith Barney for its services in connection with the
Merger an aggregate financial advisory fee based on a percentage of the total
consideration (including liabilities assumed) payable in connection with the
Merger. The fee payable to Salomon Smith Barney is currently estimated to be
approximately $3.7 million. The Company has also agreed to reimburse Salomon
Smith Barney for reasonable travel and other out-of-pocket expenses incurred by
Salomon Smith Barney in performing its services, including the reasonable fees
and expenses of its legal counsel, and to indemnify Salomon Smith Barney and
related persons against certain liabilities, including liabilities under the
federal securities laws, arising out of Salomon Smith Barney's engagement.
 
    Salomon Smith Barney has advised the Company that, in the ordinary course of
business, Salomon Smith Barney and its affiliates may actively trade or hold the
securities of the Company for their own account or for the account of customers
and, accordingly, may at any time hold a long or short position in such
securities. In addition, Salomon Smith Barney and its affiliates (including
Travelers Group Inc. and its affiliates) may maintain relationships with the
Company and affiliates of MQ.
 
    Salomon Smith Barney is an internationally recognized investment banking
firm and was selected by the Company based on Salomon Smith Barney's experience
and expertise. Salomon Smith Barney regularly engages in the valuation of
businesses and their securities in connection with mergers and acquisitions,
negotiated underwritings, competitive bids, secondary distributions of listed

and other purposes.
 
FORECASTS; LIMITS OF RELIABILITY
 
   
    The Company does not as a matter of policy make public forecasts or
projections as to future performance or earnings. With the exception of the
Acquisition Projections (as defined herein), the following projections did not
contemplate or include the CHI Acquisition.
    
 
   
    The Confidential Memorandum received by potential buyers in November 1997
contained the Management Projections, an overview of management's estimates of
the Company's future financial performance. The Management Projections are
summarized below.

                                       47
<PAGE>
    Material assumptions on which the Management Projections were based included
the following:
 
        1. Rental revenue growth is based on a 4% assumed growth rate in base
    rental business, a 15% assumed growth rate in rental revenue share
    activities and an assumed initial 50% growth rate in the SpectraCair rental
    business decreasing to 25% after fiscal 1998. Base rental growth assumed
    expansion into geographical markets where the Company currently does not
    have a presence, additional penetration in the homecare and alternate care
    markets, and new product expansions. Rental revenue share growth assumed
    additional market penetration of current revenue share products and the
    establishment of additional revenue share programs. Growth in the
    SpectraCair rental business assumed internal growth through targeted
    pricing, new product offerings, increased volume from existing customers and
    new customer development.
 
        2. Growth in the sales businesses assumed continued market expansion of
    proprietary products, expansion of such products into corporate accounts and
    new alliances with manufacturers, and it was also assumed that volume would
    increase through the addition of complementary products and the
    establishment of joint marketing arrangements with vendors and
    manufacturers.
 
        3. Growth in other revenues primarily assumed continued expansion of
    outsourcing revenues through growth in the Company's medical gases business,
    additional CAMP-Registered Trademark- and CAMP-Plus-Registered Trademark-
    programs, and expansion of manufacturer logistics and biomedical services.
    Expansion of such services would be through increased market penetration and
    volume.
 
   
        4. The cost and expense categories assumed that the historical
    relationship of individual expenses to historical revenue streams will
    remain consistent for the periods covered by the projections. Depreciation
    and amortization was based on the Company's expected depreciation and
    amortization for existing assets adjusted for projected capital expenditures
    of $15.0 million per year.
    
 
   
    Subsequent to the preparation of the Management Projections, at the request
of one of the six second-round bidders, management prepared and reviewed with
each of the second-round bidders a set of projections that assumed the
successful completion of a proposed acquisition program by the Company in its
core equipment rental business, as well as the expansion of the Support Surfaces
(as defined herein) business of its SpectraCair division and the broadening of
the Company's products and services into complementary areas, permitting it to
take advantage of its existing distribution network and customer bases (the
"Acquisition Projections"). The Acquisition Projections identified nineteen
potential acquisition targets, including CH Medical and another company which
subsequently signed a non-binding letter of intent with the Company in March
1998. The Acquisition Projections also reflected the projected effects of the
proposed expansion of the Company's business internationally and the proposed
expansion of the Company's relationship with an existing business partner. At
the time that the Acquisition Projections were prepared and made available to
the second-round bidders, there had been no substantive discussions with any of
the potential acquisition targets, although, in certain cases, there had been
preliminary discussions in respect of the target's level of interest in a
possible transaction. Under the Acquisition Projections, the Company's revenues
were projected to be approximately $255, $351, $405, $477 and $565 million for
fiscal years 1998-2002, and EBITDA was projected to be approximately $101, $145,
$165, $192 and $225 million for fiscal years 1998-2002. Following execution and
delivery of the Merger Agreement, the Company, with the consent of BRS, began to
actively investigate possible acquisitions, leading to the execution of a
definitive agreement with CHI and the non-binding letter of intent referred to
above. See "THE COMPANY--CHI Acquisition" and "--Growth Strategy." The expansion
of the Company's relationship with an existing business partner has taken place,
but has not yet resulted in additional revenues and continues to be in the
developmental stage.
    
 
    Management also prepared projections that assumed a more conservative
projected rate of sales and EBITDA growth than the Management Projections. These
projections, together with the Management Projections and certain other
materials, were utilized by Salomon Smith Barney for purposes of its financial
analysis. Under such projections, the Company's revenues were projected to be
approximately
 
                                       48
<PAGE>
$185, $209, $236, $264 and $294 million for fiscal years 1998-2002, and EBITDA
was projected to be approximately $68, $74, $81, $88 and $96 million for fiscal
years 1998-2002. Such projections were not provided to BRS or any other bidder
prior to the execution of the Merger Agreement on January 14, 1998.
 
   
    The projections described herein were not prepared with a view to public
disclosure or compliance with the published guidelines of the Commission or the
guidelines established by the American Institute of Certified Public Accountants
regarding projections or forecasts, and are included herein only because such
information was provided to the Board and, in the case of the Management
Projections and the Acquisition Projections, MQ and BRS. The projections are
subjective in many respects and thus susceptible to various interpretations and
periodic revisions based on actual experience and business developments. While
presented with numeric specificity, the projections are based upon numerous
estimates and assumptions that are inherently subject to significant business,
economic, industry and competitive uncertainties and contingencies, all of which
are difficult to predict and many of which are beyond the Company's control.
Certain assumptions on which the projections were based related to the
achievement of strategic goals, objectives and targets over the applicable
periods that are more favorable than historical results. There can be no
assurance that the assumptions made in preparing the projections will prove
accurate, and actual results may be materially greater or less than those
contained in the projections. None of the Company, MQ and BRS or their
respective financial advisors assumes any responsibility for the accuracy of any
of the projections. Neither the Company's independent auditors, nor any other
independent accountants or financial advisors, have compiled, examined or
performed any procedures with respect to the projections contained herein, nor
have they expressed any opinion or any form of assurance on such information or
its achievability, and assume no responsibility for, and disclaim any
association with, the projections. The inclusion of the projections should not
be regarded as an indication that the Company, MQ, BRS or any other person who
received such information considers it an accurate prediction of future events.
    
 
    The projections constitute forward-looking statements and involve risks and
uncertainties. The Company's actual results may differ significantly from
projected results. Factors that might cause such a difference include, but are
not limited to, the effect of changing economic or business conditions, the
impact of competition and other risk factors described more fully in the "RISK
FACTORS" section of this Proxy Statement/Prospectus and elsewhere in this Proxy
Statement/ Prospectus and the Company's other reports filed with the Commission.

<PAGE>
                                  RISK FACTORS
 
   
    Holders of MEDIQ Common Stock and MEDIQ Preferred Stock should carefully
consider certain risks related to the shares of Series A Preferred Stock to be
received by stockholders of the Company pursuant to the Merger as described
below, as well as the other information appearing in this Proxy
Statement/Prospectus.
    
 
SUBSTANTIAL LEVERAGE; ABILITY TO SERVICE DEBT; STOCKHOLDERS' DEFICIT
 
   
    The Company is expected to issue senior discount debentures and to cause
MEDIQ/PRN to issue senior subordinated debt securities and enter into a new
senior secured credit facility as described in "SOURCES AND AMOUNT OF FUNDS" to
finance a portion of the cash consideration to be paid to the holders of the
MEDIQ Common Stock and the MEDIQ Preferred Stock in the Merger, to finance the
CHI Acquisition, to refinance a portion of the indebtedness of the Company, to
pay a portion of the fees and expenses incurred in connection with the
Transactions and the CHI Acquisition and to provide for working capital
requirements. Upon consummation of the Merger, it is expected that the Company
will have substantial consolidated indebtedness. At December 31, 1997, on a pro
forma basis assuming consummation of the Transactions, but not the CHI
Acquisition, the Company would have had $428.8 million of consolidated
indebtedness, $108.2 million of mandatory redeemable preferred stock and a
stockholders' deficit of $320.5 million. Assuming consummation of the CHI
Acquisition and consummation of the Tranactions at December 31, 1997, on a pro
forma basis, the Company would have had $478.8 million of consolidated
indebtedness, $108.2 million of mandatory redeemable preferred stock and a
stockholders' deficit of $320.5 million. Upon completion of the Transactions,
the Company will have consolidated indebtedness substantially greater than the
Company's pre-Transactions consolidated indebtedness. On a pro forma basis,
assuming consummation of the Transactions and the SpectraCair Acquisition as of
October 1, 1996, but not the CHI Acquisition, the ratio of earnings to fixed
charges of the Company would have been .31 to 1 and .33 to 1 for the year ended
September 30, 1997 and the three months ended December 31, 1997, respectively
and, assuming consummation of the Transactions, the SpectraCair Acquisition and
the CHI Acquisition as of October 1, 1996, would have been .35 to 1 and .38 to 1
for the year ended September 30, 1997 and the three months ended December 31,
1997, respectively. See "PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS."
The Company believes it is likely to incur additional indebtedness in the
future, subject to certain limitations contained in the instruments and
documents governing its indebtedness. Accordingly, the Company will have
significant debt service obligations.
    
 
    The degree to which the Company is leveraged will have important
consequences for the Company, including the following: (i) the Company's ability
to obtain additional financing for working capital, capital expenditures,
acquisitions, debt service requirements or other purposes may be impaired; (ii)
a substantial portion of MEDIQ/PRN's cash flow from operations will be required
to pay its interest expense and principal repayment obligations and will not be
available for its general corporate needs; (iii) the Company's flexibility to
adjust to changing market conditions may be limited, and its ability to compete
against its less highly leveraged competitors may be reduced; (iv) the Company
may be far more vulnerable in the event of a downturn in its business or in the
economy generally; and (v) to the extent that MEDIQ/ PRN incurs borrowings under
the New Credit Facility, which borrowings will be at variable rates, it will be
vulnerable to increases in interest rates. See "SOURCES AND AMOUNT OF FUNDS."
 
   
    The successful implementation of the Company's business strategy is
necessary for the Company to be able to meet its anticipated debt service
requirements. In addition, the Company's ability to meet its debt service
requirements will depend on the Company's future performance, which is subject
to a number of factors, most of which are outside the Company's control. There
can be no assurance that the Company will generate sufficient cash flow from
operating activities to meet its debt service and working capital requirements.
Although the Company expects that the Discount Debentures will not require cash
interest payments for a number of years after the Effective Time, interest will
accrue during such time and, after
    
 
                                       50
<PAGE>
   
five years, the Company will be required to make cash interest payments thereon.
Moreover, the Company expects that the New Credit Facility will require cash
interest payments beginning in 1998 and that the Senior Subordinated Notes will
require cash interest payments beginning       , 1998. The Exchangeable
Debentures also currently require cash interest payments. In addition, the
Company expects that the principal of such loans and the entire principal amount
of the Exchangeable Debentures will be repaid prior to the mandatory redemption
date of the Series A Preferred Stock. See "SOURCES AND AMOUNT OF FUNDS." All or
a portion of such indebtedness will need to be refinanced at or prior to the
mandatory redemption date. There can be no assurance that any refinancing will
be possible at that time or that any possible refinancing will be on terms that
are acceptable to the Company. In the absence of such refinancing, the Company
could be forced to dispose of assets in order to make up for any shortfall in
the payments due on its indebtedness under circumstances that might not be
favorable to realizing the highest price for such assets, and there can be no
assurance that the Company's assets could be sold quickly enough, or for
sufficient amounts, to enable the Company to meet its obligations, including its
obligations with respect to the mandatory redemption of the Series A Preferred
Stock.
    
 
   
    In addition, the substantial leverage will have a negative effect on the
Company's net income. For the fiscal year ended September 30, 1997 and the three
months ended December 31, 1997, the Company's loss from continuing operations,
on a pro forma basis as adjusted to give effect to the Transactions and the
SpectraCair Acquisition as of October 1, 1996, but not the consummation of the
CHI Acquisition, would have been $17.4 million and $3.3 million, respectively,
compared to the historical amounts for such periods of a $2.2 million loss and
income of $1.3 million, respectively. Pro forma interest expense (net of
interest income) would have been $41.7 million and $10.9 million for the fiscal
year ended September 30, 1997 and the three months ended December 31, 1997,
respectively, as compared to $17.0 million and $3.4 million for the same periods
on a historical basis. On a pro forma basis as adjusted to give effect to the
Transactions, the SpectraCair Acquisition and the CHI Acquisition as of October
1, 1996, the Company's loss from continuing operations for the fiscal year ended
September 30, 1997 and the three months ended December 31, 1997 would have been
$17.4 million and $3.1 million, respectively. Pro forma interest expense (net of
interest income) would have been $46.0 million and $11.9 million for the fiscal
year ended September 30, 1997 and the three months ended December 31, 1997,
respectively. See "PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS."
    
 
   
    In October 1997, Standard & Poor's ("S&P") ratings for the Company and
MEDIQ/PRN were placed on CreditWatch with developing implications as a result of
the Company's decision to explore strategic alternatives. On January 20, 1998,
S&P revised the implication from developing to negative.
    
 
RESTRICTIVE COVENANTS
 
   
    The Company expects the indentures (the "Indentures") governing the Discount
Debentures and the Senior Subordinated Notes and the terms of the New Credit
Facility to contain, and any additional financing agreements are likely to
contain, certain restrictive covenants. The restrictions expected to be
contained in the Indentures and the New Credit Facility will affect, and in some
cases will significantly limit or prohibit, among other things, the ability of
the Company to incur indebtedness, make prepayments of certain indebtedness, pay
dividends, make acquisitions and other investments, engage in transactions with
stockholders and affiliates, issue capital stock, create liens, sell assets and
engage in mergers and consolidations. In addition to the restrictive covenants
described above, the Company expects that the New Credit Facility will require
MEDIQ/PRN to maintain a number of financial ratios. The failure of MEDIQ/ PRN
and its subsidiaries to maintain such ratios would constitute events of default
under the New Credit Facility, notwithstanding the ability of the Company to
meet its debt service obligations (including its obligations with respect to the
Securities). In the event the Company or MEDIQ/PRN fails to comply with the
various covenants contained in the New Credit Facility or the Indentures, as
applicable, it would be in default thereunder, and in any such case, the
maturity of substantially all of its long-term indebtedness could be
accelerated. A default under either of the Indentures would also constitute an
event of default
    
 
                                       51
<PAGE>
   
under the New Credit Facility. The Company expects that the New Credit Facility
will prohibit the redemption of the Series A Preferred Stock any time prior to
the repayment of the borrowings under the New Credit Facility. See "SOURCES AND
AMOUNT OF FUNDS."
    
 
CONTROLLING STOCKHOLDERS OF THE COMPANY
 
   
    Upon consummation of the Merger, it is expected that the Investors will own
at the Effective Time approximately 82.9% of the Surviving Corporation Common
Stock, 71.8% of the Series A Preferred Stock, 53.4% of the Series B Preferred
Stock and 96.5% of the Series C Preferred Stock. Accordingly, such persons will
control the Company and have the power to elect a majority of its directors, to
appoint new management and to approve any action requiring the approval of the
holders of any class of the Company's capital stock, including the adoption of
most amendments to the Company's Certificate of Incorporation and the approval
of mergers or sales of substantially all of the Company's assets or the creation
of new classes or series of the Company's capital stock. The directors so
elected will have the authority to effect decisions affecting the capital
structure of the Company, including the issuance of additional capital stock
(including classes or series which may be senior to, or PARI PASSU with, the
Series A Preferred Stock), the implementation of stock repurchase programs and
the declaration of dividends. There is no present intention to issue additional
capital stock senior to or PARI PASSU with Series A Preferred Stock; however,
there can be no assurance that such stock will not be issued in the future.
There is no present intention to engage in any post-Merger transaction that
would eliminate the Series A Preferred Stock of the Company to be issued in the
Merger to existing stockholders of the Company; however, no assurance can be
given that such a transaction will not occur in the future.
    
 
    In addition, the existence of a small number of controlling stockholders of
the Company may have the effect of making it more difficult for a third party to
acquire, or of discouraging a third party from seeking to acquire, a majority of
the outstanding equity securities of the Company. A third party would be
required to negotiate any such transaction with such stockholders and the
interests of such stockholders may be different from the interests of other
stockholders.
 
DELISTING OF MEDIQ COMMON STOCK AND MEDIQ PREFERRED STOCK FROM AMEX; UNCERTAINTY
REGARDING LIQUIDITY AND MARKET PRICE FOR SERIES A PREFERRED STOCK
 
    The Company and MQ have each agreed, pursuant to the Merger Agreement, to
cooperate in taking, or causing to be taken, all actions necessary, following
consummation of the Merger, to delist the MEDIQ Common Stock and the MEDIQ
Preferred Stock from the AMEX. The Series A Preferred Stock will not be listed
on the AMEX or any other securities exchange and will not be quoted on the
NASDAQ. Consequently, there can be no assurance that any trading market will
exist or develop for the Series A Preferred Stock after consummation of the
Merger. Shares of the Series A Preferred Stock will trade only in the
over-the-counter market. Although prices in respect of trades will be published
by the National Association of Securities Dealers, Inc. periodically in the
"pink sheets," quotes for such shares would not be readily available. As a
result, it is anticipated that the shares will trade much less frequently
relative to the trading volume of the Company's securities prior to consummation
of the Merger. At present there is no trading market for the Series A Preferred
Stock. There can be no assurance that holders will be able to sell their Series
A Preferred Stock at favorable prices or that the trading prices for the Series
A Preferred Stock will be comparable to the trading prices for MEDIQ Shares
prior to consummation of the Merger. A large number of shares of Series A
Preferred Stock may be traded by holders immediately following completion of the
Merger for various reasons, including payment of taxes. This might tend to
depress the market price of the Series A Preferred Stock.
 
    Although the stated value of the Series A Preferred Stock is set at its
liquidation preference of $10.00 per share, the valuation of the Series A
Preferred Stock is subject to uncertainties and contingencies, all of which are
difficult to predict, and the stated value of the Series A Preferred Stock and
the amounts at which the Series A Preferred Stock are reflected in the pro forma
financial information contained herein
 
                                       52
<PAGE>
are not necessarily reflective of the prices at which the Series A Preferred
Stock will actually trade at or after the time of their issuance, whether before
or after such securities are fully distributed. The liquidity of and the market
prices for the Series A Preferred Stock can be expected to vary with changes in
market and economic conditions, the financial condition and prospects of the
Company and other factors that generally influence the market prices of
securities, including in particular further fluctuations in the market for high
yield securities generally. Such fluctuations in the high yield market may
significantly affect liquidity and market prices independent of the financial
performance of and prospects for the Company and its subsidiaries. In addition,
the Series A Preferred Stock may trade at prices that do not fully reflect the
value of accrued but undeclared dividends. Due in part to such considerations,
the Board of Directors and the Special Committee, with the assistance of the
Company's financial advisor, have attributed to the Series A Preferred Stock a
significant discount from its stated value. See "SPECIAL FACTORS."
 
   
RANKING OF SERIES A PREFERRED STOCK
    
 
   
    The Series A Preferred Stock will rank junior in right of payment to all
existing and future liabilities and obligations (whether or not for borrowed
money) of the Company and to any Series A Senior Securities (as defined herein).
The Series A Preferred Stock will rank senior in right of payment to any Series
A Junior Securities (as defined herein) and on a parity with any Series A Parity
Securities (as defined herein). See "DESCRIPTION OF MEDIQ CAPITAL STOCK
FOLLOWING THE MERGER-- Series A Preferred Stock--Rank."
    
 
LIMITED VOTING RIGHTS
 
    Holders of Series A Preferred Stock will have very limited voting rights as
set forth in "MEDIQ CAPITAL STOCK AFTER THE MERGER--Preferred Stock" and will
have no rights with respect to the election of directors in the Surviving
Corporation, which rights are vested exclusively in the holders of the Surviving
Corporation Common Stock.
 
RESTRICTIONS ON THE PAYMENT OF DIVIDENDS
 
   
    Although dividends will accrue on the Series A Preferred Stock at the annual
rate of 13.0%, the declaration and payment of cash dividends will be subject to
the discretion of the Board of Directors. See "DESCRIPTION OF MEDIQ CAPITAL
STOCK FOLLOWING THE MERGER--Series A Preferred Stock." The ability of the
Company to declare and pay such dividends will depend upon its financial
condition, cash requirements, future prospects, and other factors deemed
relevant by the Board of Directors. The ability of the Board of Directors to
declare and pay such dividends may also be limited by the terms of any financing
arrangements which the Company may enter into in connection with the Merger,
including the Indentures and the New Credit Facility. See "SOURCES AND AMOUNT OF
FUNDS." In addition, under Delaware law, the Company is permitted to pay
dividends on its capital stock, including the Series A Preferred Stock, only out
of its surplus or, in the event that it has no surplus, out of its net profits
for the year in which a dividend is declared or for the immediately preceding
fiscal year. Surplus is defined as the excess of a company's total assets over
the sum of its total liabilities plus the par value of its outstanding capital
stock. In order to pay dividends in cash, the Company must have surplus or net
profits equal to the full amount of the cash dividend at the time such dividend
is declared. In determining the Company's ability to pay dividends, Delaware law
permits the Board of Directors of the Company to revalue the Company's assets
and liabilities from time to time to their fair market values in order to create
surplus. The Company cannot predict what the value of its assets or the amount
of its liabilities will be in the future and, accordingly, there can be no
assurance that the Company will be able to pay cash dividends on the Series A
Preferred Stock. See "--Substantial Leverage; Ability to Service Debt;
Stockholders' Deficit" and "PRO FORMA CONDENSED CONSOLIDATED FINANCIAL
STATEMENTS." Even if the Company has the ability to pay cash dividends on the
Series A Preferred Stock, the declaration and payment of such dividends will
remain subject to the discretion of the Board of Directors
    
 
                                       53
<PAGE>
to declare and pay any such cash dividends and there can be no assurance that
the Board of Directors will declare and pay cash dividends in respect of any
given dividend payment period.
 
POSSIBLE TERMINATION OF EXCHANGE ACT REPORTING
 
   
    After the Effective Time, the Company may not, depending upon the number of
holders of the Series A Preferred Stock, be subject to the reporting
requirements of the Exchange Act. The Company and MQ have agreed that, for a
period of twenty-four months after the Effective Time, the Company will continue
to comply with the periodic reporting requirements of the Exchange Act and
provide reports or information to its public stockholders so long as at least
500,000 shares of the Series A Preferred Stock remain outstanding. After the
expiration of the twenty-four month period following the Merger, the Company
may, depending upon the number of holders of the Series A Preferred Stock and
other factors, no longer file periodic reports under the Exchange Act or provide
reports or information to its stockholders. As a result, the information
available to stockholders regarding the financial condition of the Company could
be reduced, which reduction could have a material adverse effect on the value of
the Series A Preferred Stock. The Company currently anticipates being required
to file periodic reports under the Exchange Act pursuant to the Senior
Subordinated Notes and Discount Debentures, although such securities may be
repaid subsequent to the Effective Time and the Company's obligation to file
periodic reports under the Exchange Act in respect of such securities may
subsequently terminate.
    
 
   
REQUIRED OFFER TO PURCHASE EXCHANGEABLE DEBENTURES
    
 
   
    The Merger will result in a "Change of Control" under the Exchangeable
Debentures. Under the terms of the Exchangeable Debentures, within 20 days after
a "Change of Control," the Company is required to notify holders thereof of
their right to require the Company to purchase the Exchangeable Debentures at
100% of their principal amount plus accrued interest. Given current trading
prices for the Exchangeable Debentures, the Company does not anticipate a
significant number of holders tendering their Exchangeable Debentures for
purchase by the Company. However, circumstances occurring subsequent to the
consummation of the Merger may cause holders of the Exchangeable Debentures to
tender them. In the event the Company is required to purchase any Exchangeable
Debentures, it expects it will obtain the funds to make such purchases by
drawing upon the Revolving Credit Facility (as defined herein) included in the
New Credit Facility.
    
 
COMPETITION
 
    The movable medical equipment rental industry is highly competitive and the
Company, which operates throughout the United States, encounters competition in
all locations in which it operates. Competition is generated from (i) movable
medical equipment manufacturers which sell medical equipment directly to health
care providers and which the Company believes generate the strongest
competition; (ii) general leasing and financing companies and financial
institutions, such as banks, which finance the acquisition of movable medical
equipment by health care providers; and (iii) national, regional and local
medical equipment renting and leasing companies and medical equipment
distributors which rent medical equipment to health care providers. The Company
believes that the key factors influencing the decision regarding the selection
of a medical equipment rental vendor include availability and quality of movable
medical equipment, service and price. The Company faces competitive pressure in
all of its markets from existing competitors and from the potential entry of new
competitors. Although the Company believes that it is able to demonstrate the
cost-effectiveness of renting movable medical equipment on a long term basis,
the Company believes that many health care providers will continue to purchase a
substantial portion of their movable medical equipment.
 
                                       54
<PAGE>
ABILITY TO IMPLEMENT ACQUISITION STRATEGY AND ABILITY TO MANAGE GROWTH
 
   
    A key component of the Company's business strategy is the growth of the
Company's product and customer base through the acquisition of companies in
similar lines of business. The Company has entered into an agreement to acquire
certain assets of CH Medical as described in "THE COMPANY--CHI Acquisition," and
has also entered into a non-binding letter of intent with respect to another
potential acquisition. The Company believes that there currently exist ample
opportunities for other acquisitions, although there can be no assurance that
the Company will be able to consummate the CHI Acquisition or such other
potential acquisition or successfully capitalize on any other opportunities or
that such other opportunities will be available in the future. Although the New
Credit Facility is expected to include financing commitments sufficient to
finance the CHI Acquisition as well as other future acquisitions, in order to
capitalize on any other acquisition opportunities, the Company may need to
obtain additional capital and obtain certain federal and/or state regulatory
approvals, including approvals required to consummate the CHI Acquisition. To
raise additional capital, the Company may elect to undertake additional debt
financings. The issuance of additional debt securities or borrowings would
result in additional leverage and reduced working capital. Additionally, the
issuances of additional debt securities or borrowings will be restricted by the
terms of the Indentures and the New Credit Facility. There can be no assurance
that the Company will be able to obtain the necessary approvals or such
financing on terms acceptable to the Company, if at all, and the inability to
obtain such regulatory approvals or financing when desired could have a material
adverse effect on the Company's ability to implement its acquisition strategy
and capitalize on profitable opportunities.
    
 
    Following the Merger, the Company intends to grow and expand its business
through internal expansion and acquisitions. If such growth occurs, it will
place demands on the Company's management, employees, operations and physical
and financial resources. To manage its growth, the Company must continue to
implement and improve its operational and financial systems and to expand, train
and manage its employee base, and any inability of the Company to attract and
retain the executive and managerial personnel required by its expanding business
could have a material adverse effect on the results of operations and financial
condition of the Company. If the Company's systems, procedures or controls are
not adequate to support the Company's operations, management may not be able to
achieve the rapid expansion necessary to exploit potential market opportunities
for the Company's products and services.
 
   
    The CHI Acquisition, if consummated, and any additional acquisitions will
involve a number of additional risks, including diversion of management's
attention from other business concerns, the possible loss of key employees of CH
Medical and other acquired businesses and the potential difficulties in
integrating the operations of CH Medical and other acquired businesses with
those of the Company. The Company has not previously operated a manufacturer of
Support Surfaces or other medical equipment and there can be no assurance that
the Company will be able to successfully operate the manufacturing business of
CHI. In light of the foregoing, no assurance can be given as to the effect of
the CHI Acquisition and any other acquired businesses on the Company's business
or results of operations. See "THE COMPANY--CHI Acquisition."
    
 
RELIANCE ON KEY PERSONNEL
 
   
    The Company's success depends to a significant degree upon the continued
contributions of management, some of whom would be difficult to replace. The
loss of the services of certain members of senior management could have a
material adverse effect on the Company. Although Messrs. Carroll and Kaplan and
certain other members of senior management are expected to continue to be
stockholders of the Company following consummation of the Merger and will have
employment contracts with the Company, there can be no assurance that the
services of such personnel will continue to be available to the Company.
    
 
                                       55
<PAGE>
DEPENDENCE ON SALES REPRESENTATIVES AND SERVICE SPECIALISTS
 
    The Company believes that to be successful it must continue to hire, train
and retain highly qualified sales representatives and service specialists. The
Company's sales growth has been supported by hiring and developing new sales
representatives and adding, through acquisitions, established sales
representatives whose existing customers generally have become customers of the
Company. Due to the relationships developed between the Company's sales
representatives and its customers, upon the departure of a sales representative,
the Company faces the risk of losing the representative's customers, especially
if the representative were to represent one of the Company's competitors. In
addition, there has been, and the Company expects that there will continue to
be, intense competition in its industry for divisional managers and experienced
sales representatives. There can be no assurance that the Company will be able
to retain or attract qualified personnel in the future. Failure by the Company
to attract or retain such personnel could have a material adverse effect on the
Company's business, financial condition or results of operations.
 
REGULATION OF THE HEALTH CARE INDUSTRY
 
    The Company focuses its business on providing services to health care
institutions, particularly hospitals. The health care industry is subject to
extensive government regulation, licensure and prescribed operating procedures.
The continued acceptance of the Company's services and products by its customers
will depend, to a very significant degree, upon whether such services and
products will be in compliance with applicable regulations or will assist health
care institutions in complying with such regulations. While the Company closely
monitors such regulations and designs its services and products accordingly, a
substantial change in the level of regulation or the substance of particular
regulations could have a material adverse effect on the Company's business,
financial condition or results of operations.
 
UNCERTAINTY OF HEALTH CARE REFORM; REIMBURSEMENT OF HEALTH CARE COSTS
 
   
    There are widespread efforts to control health care costs in the United
States and abroad. As an example, The Balanced Budget Act of 1997 (the "BBA")
significantly reduces Federal spending on Medicare and Medicaid over the next
five years by reducing annual payment updates to acute care hospitals, changing
payment systems for both skilled nursing facilities and home health care
services from cost-based to prospective payment systems, eliminating annual
payment updates for durable medical equipment ("DME"), and allowing states
greater flexibility in controlling Medicaid costs at the state level. The
Company cannot reliably predict the timing of or the exact effect which these or
similar initiatives could have on the pricing and profitability of, or demand
for, the Company's products. However, certain provisions of the BBA, such as the
changes in the manner Medicare Part A reimburses skilled nursing facilities, may
change the manner in which the Company's customers make renting and purchasing
decisions and could have a material adverse effect on the Company. The Company
also believes it is likely that efforts by governmental and private payors to
contain costs through managed care and other efforts and to reform health
systems will continue in the future. There can be no assurance that current or
future initiatives will not have a material adverse effect on the Company's
business, financial condition or results of operations.
    
 
   
    The Company's products are rented and sold principally to health care
providers who receive reimbursement for the products and services they provide
from various public and private third party payors, including Medicare, Medicaid
and private insurance programs. If the CHI Acquisition is consummated, the
Company will also act as a durable medical equipment supplier under 42 U.S.C.
1395 et seq. and, as such, will furnish products directly to customers and bill
third party payors. As a result, the demand for the Company's products in any
specific care setting is dependent in part on the reimbursement policies of the
various payors in that setting. In order to be reimbursed, the products
generally must be found to be reasonable and necessary for the treatment of
medical conditions and must otherwise fall within the payor's list of covered
services. In light of increased controls on Medicare spending, there can be no
    
 
                                       56
<PAGE>
assurance of the outcome of future coverage or payment decisions for any of the
Company's products by governmental or private payors. If providers, suppliers
and other users of the Company's products and services are unable to obtain
sufficient reimbursement for the provision of the Company's products, a material
adverse impact on the Company's business, financial condition or results of
operations will likely result.
 
CONSOLIDATION OF PURCHASING ENTITIES
 
    One result of the health care reform debate in the United States is that
many health care providers have merged or consolidated with other members of
their industry in an effort to reduce costs or achieve operating synergies.
Accordingly, because larger purchasers tend to have more leverage in negotiating
prices and because this consolidation often results in the renegotiation of
contracts and in the granting of price concessions, this trend could have a
material adverse effect on the Company's business, financial condition or
results of operations.
 
FRAUD AND ABUSE LAWS
 
   
    The Company and its customers are subject to various federal and state laws
pertaining to health care fraud and abuse, including prohibitions on the
submission of false claims and the payment or acceptance of kickbacks or other
remuneration in return for the purchase or rental of Company products. The
United States Department of Justice and the Office of the Inspector General of
the United States Department of Health and Human Services have launched an
enforcement initiative which specifically targets the long-term care, home
health and DME industries. Sanctions for violating these laws include criminal
penalties and civil sanctions, including fines and penalties, and possible
exclusion from Medicare, Medicaid and other federal health care programs. There
can be no assurance that the Company's practices, including its practices with
respect to the CHI business, or the practices of the Company's customers will
not be challenged under federal and state fraud and abuse laws in the future or
that such a challenge would not have a material adverse effect on the business,
financial condition or results of operations of the Company.
    
 
PRODUCT LIABILITY
 
   
    The manufacture and marketing of medical products entails an inherent risk
of product liability claims. Although the Company has not experienced any
significant losses due to product liability claims and currently maintains
umbrella liability insurance coverage, there can be no assurance that the amount
or scope of the coverage maintained by the Company will be adequate to protect
it in the event a significant product liability claim is successfully asserted
against the Company.

                              THE SPECIAL MEETING
 
MATTERS TO BE CONSIDERED
 
   
    The purpose of the Special Meeting is to consider and vote upon a proposal
to approve and adopt the Merger Agreement entered into between MQ and the
Company, and the transactions contemplated thereby, including the Merger. If the
Merger is approved by the stockholders of the Company, MQ will merge with and
into the Company, and each issued and outstanding share of MEDIQ Common Stock
and each issued and outstanding share of MEDIQ Preferred Stock will be converted
into the right to receive (i) $13.75 in cash, without interest, and (ii) 0.075
of a share of Series A Preferred Stock of the Surviving Corporation having the
terms described in "DESCRIPTION OF MEDIQ CAPITAL STOCK FOLLOWING THE
MERGER--Series A Preferred Stock," except for MEDIQ Shares owned directly or
indirectly by MQ or the Company or any direct or indirect subsidiary of MQ or
the Company, the Rolled Shares and Dissenting Shares. Each Share that is issued
and outstanding immediately prior to the Effective Time and owned by MQ or the
Company or any direct or indirect subsidiary of MQ or the Company will be
canceled and no payment of any consideration will be made with respect thereto.
If the Merger is approved by the stockholders of the Company, each share of
capital stock of MQ issued and outstanding immediately prior to the Effective
Time (including any shares of capital stock issued by MQ in exchange for the
Rolled Shares) will be converted into and thereafter represent the same number
of shares of the same class of capital stock of the Company, provided that, each
of the Rolled Shares not owned by MQ immediately prior to the Effective Time
will be converted into and thereafter represent the number of shares of capital
stock of the Company as contemplated by the Rollover Agreement. If the Merger is
approved, a majority of the outstanding shares of each class of capital stock of
the Company will be held by the Investors (see "THE MERGER--Conversion of MQ
Stock" and "RISK FACTORS--Controlling Stockholders of the Company"). Although
the Investors will hold a majority of the outstanding shares of each class of
capital stock of the Company at the Effective Time, there is no current
intention to engage in any post-Merger transaction which would eliminate the
Series A Preferred Stock to be issued in the Merger to existing stockholders of
the Company. However, no assurance can be given that such a transaction will not
occur in the future. The Merger Agreement (including the principal exhibits
thereto) is attached to this Proxy Statement/Prospectus as Annex A. See "THE
MERGER" and "CERTAIN PROVISIONS OF THE MERGER AGREEMENT." The Special Committee
and the Board of Directors of the Company by unanimous vote, have each approved
the Merger and the Merger Agreement and the transactions contemplated thereby
and have each recommended that the Company's stockholders vote FOR approval of
the Merger, the Merger Agreement and the transactions contemplated thereby.
    
 
REQUIRED VOTES
 
   
    The Merger requires the approval at the Special Meeting of (i) the holders
of a majority of the outstanding voting power of the MEDIQ Common Stock and the
MEDIQ Preferred Stock, voting together as a single class and (ii) the holders of
a majority of the shares outstanding MEDIQ Preferred Stock. Adoption and
approval of the Merger Agreement and the transactions contemplated thereby,
including the Merger, require (i) 41,014,904 affirmative votes of the holders of
the outstanding voting power of the MEDIQ Shares, voting together as a single
class, with each share of MEDIQ Common Stock being entitled to one vote and each
share of MEDIQ Preferred Stock being entitled to ten votes, and (ii) the
affirmative vote of stockholders holding 3,133,000 shares of MEDIQ Preferred
Stock, being a majority of the shares of MEDIQ Preferred Stock entitled to vote
thereon.
    
 
   
    Pursuant to Stockholders Agreements between MQ and certain stockholders of
the Company, holders of 4,701,464 shares of MEDIQ Common Stock and 4,730,006
shares of MEDIQ Preferred Stock, representing approximately 24% of the
outstanding MEDIQ Common Stock (without giving effect to the conversion of any
shares of MEDIQ Preferred Stock into shares of MEDIQ Common Stock),
approximately 75% of the outstanding MEDIQ Preferred Stock and approximately 63%
of the total voting power of the MEDIQ Stock, voting together as a single class
(in each case without giving effect to the exercise of
    
 
                                       58
<PAGE>
any outstanding options to acquire MEDIQ Stock) have agreed, subject to certain
limitations, to vote their shares in favor of the Merger, the Merger Agreement
and any other actions contemplated thereby. The affirmative vote of the shares
of MEDIQ Stock subject to the Stockholder Agreements will be sufficient to
approve the Merger and the Merger Agreement. See "THE STOCKHOLDER AGREEMENTS."
Approval of the Merger by at least a majority of the stockholders who are not
affiliated with the Company is not required.
 
VOTING AND REVOCATION OF PROXIES
 
    Shares of MEDIQ Stock that are entitled to vote and are represented by a
Proxy properly signed and received at or prior to the Special Meeting, unless
subsequently properly revoked, will be voted in accordance with the instructions
indicated thereon. If a Proxy is signed and returned without indicating any
voting instructions, shares of MEDIQ Stock represented by such Proxy will be
voted FOR the proposal to approve and adopt the Merger Agreement and the
transactions contemplated thereby, including the Merger. Abstentions and broker
non-votes will be counted as present for the purposes of determining whether a
quorum is present but will not be counted as votes cast in favor of the Merger
Agreement. Because the outcome of the vote on the Merger Agreement and the
transactions contemplated thereby, including the Merger, is based on a
percentage of affirmative votes entitled to be cast by the holders of the
outstanding shares of MEDIQ Preferred Stock and MEDIQ Stock, abstentions and
broker non-votes will have the same effect as a vote against the proposal. The
Board of Directors of the Company is not currently aware of any business to be
acted upon at the Special Meeting other than as described herein. If, however,
other matters are properly brought before the Special Meeting or any
adjournments or postponements thereof, the persons appointed as proxies will
have discretion to vote or act thereon in accordance with their best judgment.
The persons appointed as proxies may not exercise their discretionary voting
authority to vote any Proxy in favor of any adjournments or postponements of the
Special Meeting if such proxy contains an instruction to vote against the
approval of the Merger Agreement.
 
    Any Proxy given pursuant to this solicitation may be revoked by the person
giving it at any time before the shares represented by such Proxy are voted at
the Special Meeting by (i) attending and voting in person at the Special
Meeting, (ii) giving notice of revocation of the Proxy at the Special Meeting,
or (iii) delivering to the Secretary of the Company (a) a written notice of
revocation or (b) a duly executed Proxy relating to the same shares and matters
to be considered at the Special Meeting, bearing a date later than the
previously executed Proxy. Attendance at the Special Meeting will not in and of
itself constitute a revocation of a Proxy. All written notices of revocation and
other communications with respect to revocation of proxies should be addressed
as follows: MEDIQ Incorporated, One MEDIQ Plaza, Pennsauken, NJ 08110-1460,
Attention: Secretary, and must be received before the taking of the votes at the
Special Meeting.
 
RECORD DATE; STOCK ENTITLED TO VOTE; QUORUM
 
   
    Only holders of MEDIQ Stock at the close of business on April 1, 1998 (the
"Record Date") will be entitled to receive notice of and to vote at the Special
Meeting. At the close of business on the Record Date, the Company had
outstanding and entitled to vote 19,369,826 shares of MEDIQ Common Stock and
6,265,998 shares of MEDIQ Preferred Stock. The approximate number of record
holders of MEDIQ Shares on the Record Date is 1,706. Because the outcome of the
vote on the Merger Agreement and the transactions contemplated thereby,
including the Merger, is based on the percentage of affirmative votes entitled
to be cast by the holders of all outstanding shares of MEDIQ Preferred Stock and
MEDIQ Stock, abstentions and broker non-votes will have the same effect as a
vote against this proposal.
    
 
   
    The presence, in person or by proxy, at the Special Meeting of (i) the
holders of shares of MEDIQ Stock representing a majority of the total number of
votes authorized to be cast by outstanding shares of MEDIQ Stock and (ii) the
holders of a majority of the outstanding shares of MEDIQ Preferred Stock, in
each case, at the close of business on the Record Date, is necessary to
constitute a quorum for the
    
 
                                       59
<PAGE>
transaction of business. Shares of MEDIQ Stock represented by Proxies which are
marked "abstain" or which are not marked as to any particular matter or matters
will be counted as shares present for purposes of determining the presence of a
quorum on all matters. Proxies relating to "street name" shares that are voted
by brokers will be counted as shares present for purposes of determining the
presence of a quorum on all matters, but will not be treated as shares having
voted at the Special Meeting as to any proposal as to which authority to vote is
withheld by the broker. The presence, in person or by proxy, of the shares of
MEDIQ Stock subject to the Stockholder Agreements will constitute a quorum for
the transaction of business.
 
SOLICITATION OF PROXIES
 
    The Company will bear the cost of the solicitation of Proxies and the cost
of printing and mailing this Proxy Statement/Prospectus. In addition to
solicitation by mail, the directors, officers and employees of the Company may
solicit Proxies from stockholders of the Company by telephone, telegram or in
person. Such directors, officers and employees will not be additionally
compensated for any such solicitation but may be reimbursed for out-of-pocket
expenses in connection therewith. Arrangements will also be made with brokerage
houses and other custodians, nominees and fiduciaries for their forwarding of
solicitation material to the beneficial owners of shares held of record by such
persons and the Company will reimburse such custodians, nominees and fiduciaries
for their reasonable out-of-pocket expenses in connection therewith.
 
    MEDIQ STOCKHOLDERS SHOULD NOT SEND STOCK CERTIFICATES WITH THEIR PROXY
CARDS.
 
DISSENTERS' RIGHTS
 
    A holder of shares of MEDIQ Stock wishing to exercise dissenters' rights of
appraisal must, before the taking of the vote on the Merger at the Special
Meeting, deliver to the Company a written demand for appraisal of such shares. A
demand for appraisal will be sufficient if it reasonably informs the Company of
the identity of the stockholder and that the stockholder intends thereby to
demand the appraisal of his or her shares and otherwise complies with applicable
law. See "DISSENTING STOCKHOLDERS' RIGHTS."

Company is One MEDIQ Plaza, Pennsauken, New Jersey 08110.
 
    BRS is a Delaware limited partnership principally engaged in the business of

organized in connection with the Merger and has not carried on any activities to
date other than those incident to its formation and the transactions
contemplated by the Merger Agreement. The address of the principal business
offices of each of BRS and MQ is c/o Bruckmann, Rosser, Sherrill & Co., Inc.,
126 East 56th Street, New York, NY 10022.
 
    The Rotko Entities consist of the Rotko 1983 Trust, Michael J. Rotko, Bessie
G. Rotko and Judith M. Shipon. The address of each of the Rotko Entities is c/o
Schnader Harrison Segal & Lewis, 1600 Market Street, Suite 3600, Philadelphia,
PA 19103-7286, Attention: John D. Iskrant, Esq.
 
   
    Mr. Carroll, Mr. Kaplan and such other persons as may be selected by the
Company and BRS prior to the Effective Time comprise the Management
Stockholders. No final determination has been made by the Company and BRS as to
the identity of such persons. See "SPECIAL FACTORS--Interests of Certain Persons
in the Merger."
    
 
EFFECTIVE TIME
 
   
    Pursuant to the Merger Agreement, upon the satisfaction or waiver (to the
extent permissible) of the conditions set forth in the Merger Agreement (see
"--Conditions to Consummation of the Merger"), MQ will merge with and into the
Company with the Company as the Surviving Corporation. The Merger will be
effected pursuant to the provisions of, and with the effect provided in, the
DGCL. The Merger will be consummated by filing with the Secretary of State of
the State of Delaware a certificate of merger in such form as may be required
by, and executed and acknowledged in accordance with, the DGCL (the "Certificate
of Merger"). At the Effective Time, the separate corporate existence of MQ will
cease, and the Surviving Corporation will continue its corporate existence under
the laws of the State of Delaware.
    
 
MERGER CONSIDERATION
 
   
    Pursuant to the Merger, each issued and outstanding share of MEDIQ Common
Stock and each issued and outstanding share of MEDIQ Preferred Stock will be
converted into the right to receive the Merger Consideration of (i) $13.75 in
cash, without interest, and (ii) 0.075 of a share of Series A Preferred Stock of
the Surviving Corporation, except for MEDIQ Shares owned directly or indirectly
by MQ or the Company, the Rolled Shares and Dissenting Shares. Each MEDIQ Share
that is issued and outstanding immediately prior to the Effective Time and owned
by MQ or the Company or any direct or indirect subsidiary of MQ or the Company
will be canceled and no payment of any consideration will be made with respect
thereto.
    
 
CONVERSION OF MQ STOCK
 
    As a result of the Merger, each share of capital stock of MQ issued and
outstanding immediately prior to the Effective Time (including any shares of
capital stock issued by MQ to the Rotko Entities in exchange for the Rolled
Shares) will be converted into and will represent the same number of shares of
the same class of capital stock of the Surviving Corporation, provided that,
each of the Rolled Shares not owned by
 
                                       61
<PAGE>
MQ immediately prior to the Effective Time will be converted into and thereafter
represent the number of shares of capital stock of the Surviving Corporation as
set forth in the Rollover Agreement. See "THE ROLLOVER AGREEMENT."
 
EXCHANGE OF SHARES
 
   
    MQ will designate a bank or trust company to act as the Exchange Agent for
the Merger (the "Exchange Agent"). The fees and expenses of the Exchange Agent
will be paid by the Surviving Corporation. As soon as practicable after the
Effective Time and in no event later than ten business days thereafter, the
Surviving Corporation will cause the distribution to holders of record of the
certificates representing the MEDIQ Stock (each a "Certificate") and Option
Agreements (as of the Effective Time) of (i) notice of the effectiveness of the
Merger and (ii) a form of letter of transmittal and other appropriate materials
and instructions for use in effecting the surrender of the Certificates for
payment of the Merger Consideration therefor and in effecting the surrender of
the Option Agreements for payment of the Option Consideration therefor. In the
event any Certificate or Option Agreement has been lost or destroyed, the
Exchange Agent will be authorized to accept an affidavit from the record holder
of such Certificate or the party to such Option Agreement in a form reasonably
satisfactory to the Surviving Corporation, subject to other conditions as the
Surviving Corporation may reasonably impose (including the posting of an
indemnity bond or other surety). Upon the surrender of each such Certificate,
together with such letter of transmittal, duly completed and validly executed in
accordance with the instructions thereto, the Exchange Agent will pay out of the
payment fund to which MQ remitted the Merger Consideration and the Option
Consideration (the "Payment Fund") amounts which such holders may be entitled,
less any amounts required to be withheld pursuant to applicable tax laws. Upon
the surrender of Option Agreements formerly representing Options, together with
a letter of transmittal, duly completed and validly executed in accordance with
the instructions thereto, the Exchange Agent will pay out of such payment fund
the Option Consideration to the holders of such Option Agreements, less any
amounts required to be withheld pursuant to applicable tax laws. The Exchange
Agent will accept such Certificates and Option Agreements upon compliance with
such reasonable terms and conditions as the Exchange Agent may impose to effect
an orderly exchange thereof in accordance with normal exchange practices. Until
surrendered as contemplated in this paragraph, (i) each Certificate will be
deemed at any time after the Effective Time to represent only the right to
receive upon such surrender the Merger Consideration, and (ii) each Option
Agreement will be deemed at any time after the Effective Time to represent only
the right to receive upon such surrender the Option Consideration. No interest
will be paid or will accrue on any cash payable as Merger Consideration or in
lieu of any fractional shares of Series A Preferred Stock, as the case may be.
    
 
FRACTIONAL SHARES
 
    No certificates or scrip representing fractional shares of Series A
Preferred Stock will be issued in connection with the Merger, and such
fractional share interests will not entitle the owner thereof to vote or to any
rights of a stockholder of the Surviving Corporation after the Merger. Each
holder of MEDIQ Shares exchanged pursuant to the Merger who would otherwise have
been entitled to receive a fractional share of Series A Preferred Stock (after
taking into account all MEDIQ Shares delivered by such holder) will receive, in
lieu thereof, a cash payment (without interest) therefor in an amount equal to
the value (determined with reference to the liquidation value of the Series A
Preferred Stock) of such fractional share provided that such cash payments do
not exceed $50,000 in the aggregate. If such cash payments exceed $50,000, each
holder of MEDIQ Shares exchanged pursuant to the Merger who would otherwise have
been entitled to receive a fractional share of Series A Preferred Stock (after
taking into account all MEDIQ Shares delivered by such holder) will receive, in
lieu thereof, a cash payment (without interest) representing such holder's
proportionate interest in the net proceeds from the sale by the Exchange Agent
(following the deduction of applicable transaction costs), on behalf of all such
holders, of the Series A
 
                                       62
<PAGE>
Preferred Stock (the "Excess Shares") representing such fractions. Such sale
will be made as soon as practicable after the Effective Time.
 
CONDUCT OF BUSINESS PENDING THE MERGER
 
    Pursuant to the Merger Agreement, the Company will, and will cause each of
its subsidiaries to, carry on its respective business in the ordinary course
consistent with past practice to use commercially reasonable efforts to preserve
intact its current business organization, keep available the services of its
current officers and employees and preserve its relationships with customers,
suppliers and others having business dealings with it. Pursuant to the Merger
Agreement, the Company will, and will cause each of its subsidiaries to, use
commercially reasonable efforts to (A) maintain insurance coverages and its
books, accounts and records in the usual manner consistent with prior practices,
(B) comply in all material respects with all laws, ordinances and regulations of
governmental entities applicable to it and (C) perform in all material respects
its obligations under all contracts and commitments to which it is a party or by
which it is bound, in each case other than where the failure to so maintain,
comply or perform, either individually or in the aggregate, has not had and
would not reasonably be expected to result in a material adverse effect on the
Company.

authorizations, qualifications and orders, individually or in the aggregate,
would not have a material adverse effect on the Company.
 
   
    The obligations of the Company under the Merger Agreement are subject to,
among other things, the fulfillment or waiver (to the extent permitted by the
Merger Agreement and applicable law), prior to or at the Effective Time, of
certain conditions, including: (i) the requisite vote of the Company's
stockholders having been obtained; (ii) the representations and warranties made
by MQ in the Merger Agreement remaining true and correct in all material
respects unless the inaccuracies (without giving effect to any materiality or
material adverse effect qualifications or materiality exceptions contained
therein) in such representations and warranties, individually or in the
aggregate, have not had and would not reasonably be expected to result in a
material adverse effect with respect to MQ; (iii) MQ having performed and
complied with all covenants required by the Merger Agreement to be performed or
complied with by it on or before the Effective Time except for such
nonperformance or noncompliance which, individually or in the aggregate, has not

MQ; (iv) the applicable waiting period under the HSR Act having expired or been
otherwise terminated; (v) no preliminary or permanent injunction or other order

governmental entity (or by any other person which has a reasonable likelihood of
success) (a) challenging or seeking to restrain consummation of the Merger or
any other transactions contemplated by the Merger Agreement or seeking to obtain

seeking to prohibit or limit ownership or operation by MQ, the Company or any of
their respective subsidiaries of any material portion of the business or assets

Schedule 13E-3 having been disseminated to the extent, and for the minimum time
period required by, the Exchange Act and the rules and regulations promulgated

waive the conditions to their obligations to consummate the Merger. However, no
such waivers are presently contemplated and each of the Company and MQ have
reserved their rights under the Merger Agreement.
    
 
                                       64
<PAGE>
   
    The Company and MQ presently believe that the pending lawsuit challenging
the Merger is without merit and does not have a reasonable likelihood of success
and accordingly do not expect such lawsuit to result in a condition to the
Merger failing to be satisfied. See "THE COMPANY--Stockholder Litigation."
    
 
REGULATORY APPROVALS
 
    On February 24, 1998, the FTC and the Antitrust Division granted early
termination of the waiting period under the HSR Act with respect to the Merger
effective immediately. See "REGULATORY APPROVALS."
 
EFFECT ON STOCK AND EMPLOYEE BENEFIT MATTERS
 
    Subject to the provisions of the plans, the employee benefit plans
maintained by the Company immediately prior to the Effective Time, other than
the Company's 1997 Stock Option Plan, will continue to be maintained by the
Company after the Effective Time.
 
    Immediately prior to the Effective Time, each Option outstanding under the
Company's 1987 Stock Option Plan, 1997 Stock Option Plan or similar arrangements
will become exercisable. For each MEDIQ Share subject to an Option, the holder
of the Option will be entitled to receive the Option Consideration as provided
in the Merger Agreement. Upon payment of the Option Consideration, each Option
will terminate. With respect to any person subject to Section 16 of the Exchange
Act, the Option Consideration will be paid as soon as practicable after the
first date payment can be made without liability to such person under Section
16(b) of the Exchange Act. Payment of the Option Consideration is subject to the
Company obtaining any required consents from the holders of Options.
 
AMEX DE-LISTING
 
   
    Following the consummation of the Merger, the Company anticipates that none
of the shares of the Company's capital stock will be listed on the AMEX or any
other national securities exchange and will not be quoted on the NASDAQ Stock
Market, Inc. Notwithstanding that the Surviving Corporation may not be required
to remain subject to the reporting requirements of Section 13 or 15(d) of the
Exchange Act, MQ has agreed that, for the two years following the Effective
Time, the Surviving Corporation will file with the Commission such reports as
are specified in Section 13 and 15(d) of the Exchange Act and required to be
filed in respect of securities similar to the Series A Preferred Stock by
issuers subject to the reporting requirements of Section 13 of the Exchange Act,
such reports to be so filed at the times specified for the filings of such
reports required under such Sections; provided that the Surviving Corporation
will have no obligation with respect to the shares of Series A Preferred Stock
to file such reports if fewer than 500,000 shares of Series A Preferred Stock
remain outstanding.
    
 
RESALE OF MEDIQ PREFERRED STOCK FOLLOWING THE MERGER
 
   
    The Series A Preferred Stock to be issued in connection with the Merger will
be freely transferable, except that shares issued to any stockholder who may be
deemed to be an "affiliate" (as defined under the Securities Act) of the Company
for purposes of Rule 145 under the Securities Act will not be transferable
except in compliance with the Securities Act. This Proxy Statement/Prospectus
does not cover the resale of Series A Preferred Stock issued to any person who
may be deemed to be an affiliate of the Company. In addition, the Investors, the
Rotko Entities and the Management Stockholders may enter into agreements among
themselves and with the Company restricting the transferability of their
securities.

<PAGE>
                          SOURCES AND AMOUNT OF FUNDS
 
   
    Management and BRS estimate that the Company will require approximately
$529.5 million in cash to consummate the Merger, effect the Refinancing and pay
related fees and expenses. Such funds are expected to be provided by (i) $4.0
million of existing cash balances, (ii) $1.0 million of Revolving Loans and
$100.0 million of Term Loans under the New Credit Facility, (iii) $265.0 million
of gross proceeds from the Senior Subordinated Note Offering, (iv) $50.0 million
of gross proceeds from the Discount Debenture Offering and (v) $109.5 million of
gross proceeds from the Equity Contribution. If the CHI Acquisition is
consummated, the Company expects to draw an additional $50.0 million of Term
Loans to finance such transaction.
    
 
   
    The documentation governing the New Credit Facility, the Senior Subordinated
Notes and the Discount Debentures has not yet been finalized.
    
 
   
DESCRIPTION OF NEW CREDIT FACILITY
    
 
   
    MEDIQ/PRN's existing $142.0 million credit facility (the "Existing Credit
Facility") with a syndicate of banks led by Banque Nationale de Paris ("BNP") is
expected to be replaced by a senior secured credit facility provided to
MEDIQ/PRN in an aggregate principal amount of $275.0 million (the "New Credit
Facility").
    
 
   
    The New Credit Facility will consist of three facilities: (i) an eight-year
senior secured term loan facility in an aggregate principal amount equal to
$150.0 million (the "Term Loan Facility"); (ii) a six-year revolving credit
facility in an aggregate principal amount not to exceed $50.0 million (the
"Revolving Credit Facility"); and (iii) a six-year senior secured acquisition
facility in an aggregate principal amount not to exceed $75.0 million (the
"Acquisition Facility"). Loans made under the Acquisition Facility are referred
to as "Acquisition Loans" and loans made under the Term Loan Facility are
referred to as "Term Loans." Advances under the Revolving Credit Facility are
referred to as "Revolving Loans."
    
 
   
    Term Loans in the aggregate principal amount of $100.0 million will be drawn
on the closing date of the New Credit Facility in connection with the
Transactions. Up to an additional $50.0 million of Term Loans will be drawn upon
consummation of the CHI Acquisition. If the CHI Acquisition is not consummated
within 60 days of the Effective Date, the $50.0 million of Term Loans designated
for financing the CHI Acquisition will no longer be available to the Company or
MEDIQ/PRN. Subject to compliance with customary conditions precedent and maximum
ratios, both before and after making any acquisition, of pro forma funded debt
to consolidated EBITDA (as such term shall be defined in the New Credit
Facility) and pro forma senior debt to consolidated EBITDA (as such term shall
be defined in the New Credit Facility), Acquisition Loans will be available for
up to eighteen months after which time (the "Conversion Date") the outstanding
balance then drawn under the Acquisition Facility shall convert to an amortizing
Term Loan. Amounts repaid under the Acquisition Facility may not be re-borrowed.
Subject to compliance with customary conditions precedent, Revolving Loans will
be available at any time prior to the final maturity of the Revolving Credit
Facility. Amounts repaid under the Revolving Credit Facility may be reborrowed
prior to the final maturity of the Revolving Credit Facility, provided that
availability requirements are met. Letters of credit will mature at any time
before the sixtieth business day prior to the final maturity of the Revolving
Credit Facility.
    
 
   
    All obligations of MEDIQ/PRN under the New Credit Facility will be
unconditionally guaranteed by each existing and each subsequently acquired or
organized domestic subsidiary of MEDIQ/PRN and, to the extent no adverse tax
consequences would result, foreign subsidiary of MEDIQ/PRN (the "Guarantors").
The New Credit Facility and the related guarantees will be secured by
substantially all the assets of MEDIQ/PRN and each Guarantor, including but not
limited to (a) a first priority pledge of all the capital stock of each
Guarantor and (b) perfected first priority security interests in, and mortgages
on, substantially all tangible and intangible assets of MEDIQ/PRN and each
Guarantor.

    Borrowings under the New Credit Facility will bear interest at a floating
rate based upon, at MEDIQ/ PRN's option, (i) the higher of the prime rate of
BNP, or the federal funds effective rate plus 0.50%, plus, in the case of the
Term Loans, a margin equal to 1.50%, and in the case of the Acquisition Loans
and the Revolving Loans, a margin equal to 1.0%, or (ii) the London Interbank
Offered Rate ("LIBOR"), plus, in the case of the Term Loans, a margin equal to
2.75%, and in the case of the Acquisition Loans and the Revolving Loans, a
margin equal to 2.25%. MEDIQ/PRN may elect interest periods of one, two, three
or six months for LIBOR borrowings. Interest shall be payable at the end of each
interest period and, in any event, at least every three months.
    
 
    In addition to paying interest on outstanding principal under the New Credit
Facility, MEDIQ/PRN will be required to pay a commitment fee to the lenders in
the New Credit Facility equal to 0.50% per annum of the undrawn portion of the
commitments in respect of the facilities (subject to adjustment as set forth
below), commencing to accrue upon the execution and delivery of the credit
agreement governing the New Credit Facility (the "Credit Agreement") and payable
quarterly in arrears and upon the termination of any commitment, in each case
for the actual number of days elapsed in a 360-day year. The Credit Agreement
will contain provisions under which commitment fees and margins on interest
rates under the facilities will be adjusted in increments to be agreed upon
based on performance goals to be agreed upon.
 
   
    The Term Loans will amortize on a quarterly basis and be payable in
installments under a schedule to be agreed upon. Principal amounts outstanding
under the Acquisition Facility at the Conversion Date will amortize on a
quarterly basis and be payable in installments under a schedule to be agreed
upon. Principal amounts outstanding under the Revolving Credit Facility will be
due and payable in full at maturity. The Acquisition Facility, the Revolving
Credit Facility and the Term Loan Facility will be subject to mandatory
prepayments and reductions in the event of certain extraordinary transactions or
issuances of debt and equity by MEDIQ/PRN or any guarantor. Such facilities will
also be required to be prepaid with 75% of the Excess Cash Flow (as such term
will be defined in the Credit Agreement) of MEDIQ/PRN or, if MEDIQ/PRN's ratio
of funded debt to consolidated EBITDA (as such term shall be defined in the New
Credit Facility) for the preceding 12-month period is less than 5.0 to 1.0, 50%
of such Excess Cash Flow.
    
 
   
    The New Credit Facility will contain representations and warranties,
covenants, events of default and other provisions customary for credit
facilities of this type. MEDIQ/PRN will pay the lenders thereunder certain
syndication and administration fees, reimburse certain expenses and provide
certain indemnities, in each case which are customary for credit facilities of
this type.
    
 
   
    In the event that the New Credit Facility is not entered into on or prior to
the consummation of the Merger, pursuant to the Senior Secured Credit Facility
Commitment Letter dated as of February 2, 1998, among Bruckmann, Rosser,
Sherrill & Co., Inc. ("BRS & Co."), BNP, Credit Suisse First Boston ("CSFB") and
NationsBank, N.A. ("NB" and, together with BNP and CSFB, the "Senior Lenders"),
the Senior Lenders have agreed to provide to MEDIQ/PRN a senior secured credit
facility (the "Standby Credit Facility") in the aggregate principal amount of
$225.0 million.
    
 
   
    The Standby Credit Facility will consist of three facilities: (i) a six-year
senior secured term loan facility in an aggregate principal amount equal to
$75.0 million (the "Tranche A Term Loan Facility"); (ii) an eight-year senior
secured term loan facility in an aggregate principal amount equal to $100.0
million (the "Tranche B Term Loan Facility"); and (iii) a six-year revolving
credit facility in an aggregate principal amount not to exceed $50.0 million.
Borrowings under the Standby Credit Facility will bear interest at a floating
rate based upon, at MEDIQ/PRN's option, (i) the higher of the prime rate of BNP,
or the federal funds effective rate plus 0.50%, plus, in the case of borrowings
under the Tranche A Term Loan Facility and borrowings under the revolving
facility, a margin equal to 1.0%, and in the case of borrowings under the
Tranche B Term Loan Facility, a margin equal to 1.50%, or (ii) LIBOR plus, in
the case of borrowings under the Tranche A Term Loan Facility and borrowings
under the revolving facility, a margin equal to 2.25%, and in the case of
borrowings under the Tranche B Term Loan Facility, a margin equal to 2.75%.
    
 
                                       67
<PAGE>
   
MEDIQ/PRN may elect interest periods of one, two, three or six months for LIBOR
borrowings. Interest shall be payable at the end of each interest period and, in
any event, at least every three months.
    
 
   
    The Standby Credit Facility will have commitment fees and guaranty, security
and amortization provisions substantially similar to the New Credit Facility. In
addition, the Standby Credit Facility will contain representations and
warranties, covenants, events of default and other provisions customary for
credit facilities of this type. MEDIQ/PRN will pay the Senior Lenders certain
syndication and administration fees, reimburse certain expenses and provide
certain indemnities, in each case which are customary for credit facilities of
this type.
    
 
   
    The Senior Lenders' commitment to provide the Standby Credit Facility is
subject to conditions customary for facilities of this nature, including, but
not limited to: (i) compliance with maximum total debt levels after giving
effect to the Transactions; (ii) compliance with maximum ratios of funded debt
to consolidated EBITDA (as such term shall be defined in the Standby Credit
Facility) for MEDIQ/PRN and the Company; (iii) the satisfactory completion by
the Senior Lenders of a legal, tax and environmental due diligence investigation
of MQ and the Company and their subsidiaries; (iv) the absence of a material
adverse change in the business, condition (financial or otherwise), operations,
performance, properties or prospects of the Company and its subsidiaries taken
as a whole; (v) the absence of any material litigation or administrative
proceedings, governmental investigations, actual or threatened, or other legal
or regulatory developments that could reasonably be expected to have a material
adverse effect on (A) the business, results of operations, property, condition
(financial or otherwise) or prospects of MQ, the Company and their respective
subsidiaries, taken as a whole or (B) the validity or enforceability of any of
the documents entered into in connection with the Transactions or the rights,
remedies and benefits available to the parties thereunder; (vi) the receipt of
all material governmental or third party consents or approvals necessary in
connection with the Transactions and the absence of any governmental or judicial
action that has a reasonable likelihood of restraining, preventing or imposing
materially burdensome conditions on the Transactions; (vii) the receipt of a
satisfactory solvency opinion (and related going-concern valuation) from an
independent valuation firm; (viii) satisfaction of the Senior Lenders that there
are no "market-out" events; and (ix) satisfaction of the Senior Lenders with the
terms of any class of preferred stock of the Company.
    
 
DESCRIPTION OF THE OFFERINGS
 
   
    NOTES AND DEBENTURES.  MEDIQ/PRN intends to issue senior subordinated notes
(the "Senior Subordinated Notes") in an aggregate principal amount of $265.0
million pursuant to the Senior Subordinated Note Offering. The Company intends
to issue senior discount debentures (the "Discount Debentures") for aggregate
gross proceeds of $50.0 million pursuant to the Discount Debenture Offering. The
Senior Subordinated Notes will bear interest from the date of issuance at the
then prevailing market rate, which interest will be payable semi-annually. The
Discount Debentures will be issued at a substantial original issue discount and
will accrete in value until five years after the issuance date (and not pay
interest during such period). Thereafter interest will accrue and be payable
semi-annually on the Discount Debentures. The Senior Subordinated Note Offering
and the Discount Debenture Offering will each be made pursuant to a Rule
144A/Regulation S distribution that, in each case, is expected to be consummated
concurrently with the closing of the Merger, although no assurance to this
effect can be given. In the event that the Senior Subordinated Note Offering
and/or the Discount Debenture Offering is not consummated concurrently with the
closing of the Merger, the Standby Senior Subordinated Credit Facility and/or
the Discount Debenture Standby Purchase Arrangement, as the case may be, will be
made available or consummated, as the case may be, at the time of the
consummation of the Transactions, which would result in the incurrence of
additional interest expense by MEDIQ/PRN and the Company.
    
 
    The Senior Subordinated Notes will be senior subordinated obligations of
MEDIQ/PRN, subordinated to all existing and future senior indebtedness,
including indebtedness pursuant to the New Credit Facility. The Senior
Subordinated Notes will be unconditionally guaranteed on a senior subordinated
basis
 
                                       68
<PAGE>
   
by each subsidiary of MEDIQ/PRN that guarantees the New Credit Facility. The
Discount Debentures will be senior obligations of the Company, ranking PARI
PASSU in right of payment with all existing and future senior obligations of the
Company and will rank senior to all future subordinated debt of the Company.
    
 
    The Senior Subordinated Notes will mature on the tenth anniversary of the
date of issuance and will be non-callable for five years and will be callable at
par plus one-half of the coupon following the fifth anniversary of issuance,
declining ratably to par following the eighth anniversary of issuance. At any
time prior to the third anniversary of issuance, MEDIQ/PRN may redeem an amount
to be determined of the Senior Subordinated Notes from the proceeds of one or
more public equity offerings at a redemption price to be fixed at the time of,
and as a function of, the pricing of the Senior Subordinated Notes, plus accrued
and unpaid interest. The Discount Debentures will mature on the eleventh
anniversary of the date of issuance. The Discount Debentures will be
non-callable for five years and will be callable at par plus one-half of the
yield following the fifth anniversary of issuance, declining ratably to par
following the eighth anniversary of issuance. At any time prior to the third
anniversary of issuance, the Company may redeem the Discount Debentures in
whole, but not in part, in each case from the proceeds of one or more public
equity offerings at a redemption price to be fixed at the time of, and as a
function of, the pricing of the Discount Debentures, plus accrued and unpaid
interest.
 
    In the event of a Change of Control (as such term will be defined in the
indentures governing the Senior Subordinated Notes and the Discount Debentures,
respectively), each holder of Senior Subordinated Notes and Discount Debentures
will have the right to require MEDIQ/PRN and the Company, as the case may be, to
repurchase such holder's Senior Subordinated Notes and Discount Debentures at a
purchase price equal to 101% of the principal amount (in the case of the Senior
Subordinated Notes) or the then current accreted value (in the case of the
Discount Debentures) thereof, plus accrued and unpaid interest to the date of
purchase.
 
    The indentures governing the Senior Subordinated Notes and the Discount
Debentures, respectively, will contain certain covenants customary for high
yield securities such as the Senior Subordinated Notes and the Discount
Debentures that, among other things, will limit the ability of MEDIQ/PRN and/or
the Company to: (i) incur additional indebtedness or permit certain subsidiaries
to incur additional indebtedness; (ii) create certain liens; (iii) permit the
issuance of capital stock by certain subsidiaries; (iv) enter into certain
transactions with affiliates; (v) issue preferred stock, pay dividends or make
certain other payments or permit certain subsidiaries to pay dividends or make
other distributions; or (vi) enter into certain mergers, consolidations and
agreements to sell assets or permit other asset sales.
 
    MEDIQ/PRN and the Company will, concurrently with the Senior Subordinated
Note Offering and the Discount Debenture Offering, enter into a registration
rights agreement with the initial purchasers of the Senior Subordinated Notes
and the Discount Debentures, pursuant to which MEDIQ/PRN and the Company will
agree to file a registration statement with respect to an offer to exchange the
Senior Subordinated Notes and the Discount Debentures for new issues of debt
securities of MEDIQ/PRN and the Company, respectively, registered under the
Securities Act, with terms substantially identical to those of the Senior
Subordinated Notes and the Discount Debentures. Under certain circumstances,
MEDIQ/ PRN and the Company will be required to provide a shelf registration
statement to cover resales of the Senior Subordinated Notes and Discount
Debentures by the holders thereof. If MEDIQ/PRN and/or the Company fail to
satisfy these registration obligations, they will be required to pay liquidated
damages to the holders of Senior Subordinated Notes and Discount Debentures,
respectively, under certain circumstances.
 
   
    STANDBY SENIOR SUBORDINATED CREDIT FACILITY.  In the event that the Senior
Subordinated Note Offering is not consummated on or prior to the consummation of
the Merger, pursuant to the Bridge Loan Commitment Letter (the "Bridge
Commitment Letter") dated as of February 2, 1998 among BRS & Co., CSFB,
NationsBridge, L.L.C. ("NLLC") and BNP (together with CSFB and NLLC, the "Bridge
Lenders"), the Bridge Lenders have agreed to provide to MEDIQ/PRN a senior
subordinated credit
    
 
                                       69
<PAGE>
facility (the "Standby Senior Subordinated Credit Facility") in the aggregate
principal amount of $200.0 million.
 
   
    The loans under the Standby Senior Subordinated Credit Facility (the "Senior
Subordinated Loans") will mature 364 days after the date of issue (the "Bridge
Maturity Date"). Interest on the Senior Subordinated Loans will accrue at a
floating rate which increases over time, subject to absolute and cash caps. As
of [            ], 1998, the interest rate on the Senior Subordinated Loans
would have been [  ]%. Senior Subordinated Loans may be prepaid in whole or in
part by MEDIQ/PRN at any time upon five days prior written notice.
    
 
    The Senior Subordinated Loans will be senior subordinated obligations of
MEDIQ/PRN, subordinated to all existing and future senior indebtedness,
including indebtedness pursuant to the New Credit Facility. The Senior
Subordinated Loans will be unconditionally guaranteed on a senior subordinated
basis by each subsidiary of MEDIQ/PRN that guarantees the New Credit Facility.
 
    The Standby Senior Subordinated Credit Facility will contain representations
and warranties, affirmative covenants, reporting covenants, negative covenants,
mandatory prepayment requirements and events of default customary for similar
financing transactions. Covenants will include (but not be limited to) certain
restrictions on indebtedness, loans, investments and joint ventures, guarantees
and other contingent obligations, restricted payments, fundamental changes,
sale-leaseback transactions, transactions with affiliates, subsidiary
distributions, capital expenditures, changes in business conducted, amendment of
indebtedness and other material documents, and prepayments or repurchase of
other indebtedness, all subject to customary exceptions. MEDIQ/PRN is also
obligated under the terms of the Bridge Commitment Letter to refinance the
Senior Subordinated Loans with a public offering or private placement of senior
subordinated notes.
 
    The Senior Subordinated Loans will be due and payable in a single
installment on the Bridge Maturity Date. Each Bridge Lender will have the option
to receive, in exchange for all or a part of its loans thereunder, exchange
notes of MEDIQ/PRN ("Exchange Notes") in a principal amount equal to the
principal amount of the Senior Subordinated Loans so exchanged and ranking PARI
PASSU with the Senior Subordinated Loans; provided, that a Bridge Lender may not
exercise this option prior to the Bridge Maturity Date otherwise than in
connection with a sale of the Exchange Notes to an unaffiliated third party. If
any Bridge Lender does not exchange its Senior Subordinated Loans for Exchange
Notes on or prior to the Bridge Maturity Date, such Bridge Lender shall be
required to extend the maturity of such Senior Subordinated Loan to another date
selected by such Bridge Lender. Such Bridge Lender shall be required to continue
to extend such maturity date until such Bridge Lender exchanges the Senior
Subordinated Loans for Exchange Notes or until the tenth anniversary of the
closing date of the Standby Senior Subordinated Credit Facility. The Exchange
Notes will mature on the tenth anniversary of the closing date of the Standby
Senior Subordinated Credit Facility and will initially bear interest at a rate
determined in a customary manner (but no less than 0.50% above the then existing
interest rate of loans under the Standby Senior Subordinated Credit Facility),
which rate will increase over time, subject to absolute and cash caps. All
Senior Subordinated Loans that remain outstanding after the Bridge Maturity Date
will accrue interest at the same rate as the Exchange Notes. The indenture
relating to the Exchange Notes will include covenants customary for a high yield
senior subordinated note issue of this type.
 
    The occurrence of a change of control (the definition of which is to be
agreed) (i) will be an event of default with respect to the Senior Subordinated
Loans and (ii) will give the holders of Exchange Notes the right to require
MEDIQ/PRN to repurchase such holder's Exchange Notes at a purchase price equal
to 101% of the principal amount thereof, plus accrued and unpaid interest to the
date of purchase.
 
    MEDIQ/PRN will be required to provide a shelf registration statement to
cover resales of the Exchange Notes by the holders thereof or to effect a
registered exchange offer of registered notes identical to the Exchange Notes
for all outstanding Exchange Notes. If MEDIQ/PRN fails to satisfy these
registration obligations, it will be required to pay liquidated damages to the
holders of Exchange Notes.
 
                                       70
<PAGE>
    In the event Senior Subordinated Loans are incurred under the Standby Senior
Subordinated Credit Facility, the Company has agreed that on the closing date of
the Standby Senior Subordinated Credit Facility, the Company will place in an
escrow account warrants to purchase shares of capital stock of the Company,
exercisable for ten years at the exercise price of $.01 per share, which will
represent up to 15% (on a fully diluted basis after giving effect to the
Transactions, but excluding $20.0 million of the Series A Preferred Stock) of
each class of capital stock of the Company to be outstanding after giving effect
to the Transactions; provided, that such warrants together with any warrants
placed in escrow in connection with the Discount Debenture Standby Purchase
Arrangement shall not, in the aggregate, represent more than 15% of each such
class on a fully diluted basis (after giving effect to the Transactions, but
excluding $20.0 million of Series A Preferred Stock). The Company will be
required to enter into a registration rights agreement with respect to such
warrants. Such warrants may be released from escrow in two circumstances: (i) in
connection with an issuance of senior subordinated notes to refinance the loans
under the Standby Senior Subordinated Credit Facility ("Refinancing"); and (ii)
pursuant to an "earn-in" formula. In connection with a Refinancing, warrants
will be released from escrow upon the request of the managing underwriter of
such sale to the extent such warrants are being sold with the refinancing
securities based on then current market conditions. The "earn-in" provision
provides that on the 15 month anniversary of the closing date of the Standby
Senior Subordinated Credit Facility, holders of Senior Subordinated Loans or
Exchange Notes will receive 25% of their pro rata portion of any remaining
warrants and thereafter will receive an additional 25% at the end of each
three-month period thereafter (so long as they continue to hold Senior
Subordinated Loans or Exchange Notes) until the period which is 24 months
following the Bridge Maturity Date, when all remaining warrants will be released
to such holders.
 
   
    The Bridge Commitment Letter requires BRS & Co. to cause MQ and the Company
to become parties to such letter on or prior to the consummation of the Merger
and provides that BRS & Co. will be released automatically from all its rights,
duties and obligations thereunder when the Company becomes a party thereto.
    
 
    The funding of the Standby Senior Subordinated Credit Facility is subject,
among other things, to conditions comparable to those applicable to the funding
of the New Credit Facility, including obtaining all necessary consents and the
execution of satisfactory loan documentation.
 
   
    DISCOUNT DEBENTURE STANDBY PURCHASE ARRANGEMENT.  In the event that the
Discount Debenture Offering is not consummated on or prior to the consummation
of the Merger, pursuant to the Discount Debenture Commitment Letter (the
"Discount Debenture Commitment Letter") dated as of February 2, 1998 among BRS &
Co., Credit Suisse First Boston Corporation ("CSFBC"), NationsBanc Montgomery
Securities LLC ("NMS") and BNP (together with CSFBC and NMS, the "Initial
Purchasers"), the Initial Purchasers have agreed to purchase $30.0 million of
aggregate gross proceeds of discount debentures having terms substantially the
same as the Discount Debentures (the "Discount Debenture Standby Purchase
Arrangement"), subject to satisfaction or waiver of certain conditions customary
for arrangements of this type.
    
 
   
    If the Initial Purchasers are required to purchase such discount debentures
in accordance with the Discount Debenture Standby Purchase Arrangement, the
Company will be required to provide a shelf registration statement to cover
resales of such discount debentures by the holders thereof. If the Company fails
to satisfy this registration requirement, it will be required to pay liquidated
damages to the holders of such discount debentures.
    
 
   
    If the Initial Purchasers are required to purchase such discount debentures
in accordance with the Discount Debenture Standby Purchase Arrangement, the
Company will place in an escrow account warrants to purchase shares of capital
stock of the Company exercisable for ten years at the exercise price of $0.01
per share, which will represent up to the same percentage of capital stock of
the Company outstanding after giving effect to the Transactions as do the
warrants under the Standby Senior Subordinated Credit Facility; provided, that
such warrants together with any warrants placed in escrow in
    
 
                                       71
<PAGE>
   
connection with the Standby Senior Subordinated Credit Facility shall not, in
the aggregate, represent more than such percentage. The Company will be required
to enter into a registration rights agreement with respect to such warrants.
Such warrants may be released from escrow in two circumstances: (i) in the event
warrants are necessary for the resale of such discount debentures by an Initial
Purchaser to a party not affiliated with such Initial Purchaser and only to the
extent necessary so that the sale price (including the warrants) does not exceed
the then accreted value of such discount debentures so sold; and (ii) pursuant
to an "earn-in" formula with terms identical to those of the "earn-in" formula
applicable to the Standby Senior Subordinated Credit Facility.
    
 
   
    The Discount Debenture Commitment Letter requires BRS & Co. to cause MQ and
the Company to become parties to such letter on or prior to the consummation of
the Merger and provides that BRS & Co. will be released automatically from all
its rights, duties and obligations thereunder when the Company becomes a party
thereto.
    
 
   
    The obligation of the Initial Purchasers to purchase discount debentures
pursuant to the Discount Debenture Standby Purchase Arrangement is subject,
among other things, to conditions comparable to those applicable to the funding
of the New Credit Facility.
    
 
   
    The Discount Debenture Commitment Letter will terminate in the event that
(i) a preliminary offering circular relating to the Discount Debenture Offering
reasonably acceptable to the Initial Purchasers shall not have been printed and
ready for distribution at least 30 days prior to the date of the Special
Meeting, (ii) after completion of an offering memorandum relating to the
Discount Debenture Offering, the Initial Purchasers shall have delivered a
written notice to the Company recommending that the Company proceed with the
marketing effort for the Discount Debenture Offering and the Company elects not
to then proceed with such marketing effort or (iii) following the marketing
effort with respect to the Discount Debenture Offering, (A) the Initial
Purchasers are prepared to enter into a customary purchase agreement providing
for the purchase of the Discount Debentures and (B) the Company elects not to
enter into such purchase agreement or, having entered into such purchase
agreement, such Discount Debenture Offering is not consummated for any reason
other than the failure by the Initial Purchasers to comply with their
obligations under such purchase agreement.
    
 
EQUITY CONTRIBUTION
 
    BRS has provided MQ with a commitment letter pursuant to which BRS and
related investors have committed to invest up to $98.6 million in securities of
MQ which will be converted in the Merger into a combination of equity securities

satisfaction of all of the conditions to MQ's obligations under the Merger
Agreement.
 
   
    FFT and Galen have each committed to an affiliate of BRS to invest up to

    In the event the Merger is consummated, any transaction and management fees
payable by the Company and its subsidiaries (see "SPECIAL FACTORS--Interests of
Certain Persons in the Merger") will be shared among BRS, FFT and Galen. With
respect to any such fees, BRS shall be entitled to the first 25% thereof, and
each of BRS, FFT and Galen shall be entitled to a pro rata share of the balance
(based on the amounts actually invested by BRS, FFT and Galen in the securities
of MQ), provided that BRS in its sole discretion may modify the allocation of
any management fees at any time after the first anniversary of the Effective
Time.
 
                                       72
<PAGE>
   
    In the event the Merger is not consummated, any break-up fees (or profit in
connection with the Stock Option Agreement) entitled to be received by BRS
pursuant to the Merger Agreement shall be shared as follows: (i) BRS shall be
entitled to the first 25% of any amounts remaining after reduction for any
out-of-pocket expenses incurred and paid by BRS, FFT or Galen in connection with

negotiation of definitive documentation, including a stockholders agreement
providing, among other things, each of FFT and Galen with representation on the
Board of Directors of the Company and the fulfillment to MQ's reasonable
satisfaction of all of the conditions to MQ's obligations under the Merger
Agreement.
 
    The foregoing commitment letters have been filed as exhibits to the Schedule
13E-3 and reference is made thereto.

                      DESCRIPTION OF CERTAIN INDEBTEDNESS
    
 
   
    In July 1993, the Company issued an aggregate of $34.5 million principal
amount of Exchangeable Debentures pursuant to an indenture dated as of July 30,
1993 (the "Exchangeable Debenture Indenture") between the Company and First
Fidelity Bank, N.A. Pennsylvania ("First Fidelity") as trustee. The Exchangeable
Debentures mature on July 15, 2003. Interest on the Exchangeable Debentures
accrues and is payable at the rate of 7.5% per annum and is payable
semiannually. The Exchangeable Debentures are general unsecured obligations of
the Company and are subordinated to all existing and future "Senior
Indebtedness" (as defined in the Exchangeable Debenture Indenture) of the
Company. Approximately $10.1 million in principal amount of the Exchange
Debentures is currently outstanding.
    
 
   
    The Company may, at its option, redeem the Exchangeable Debentures, in whole
or from time to time in part, at the following redemption prices, expressed as
percentages of the principal amount, plus accrued and unpaid interests, if
redeemed during the 12 months beginning July 15 of the years indicated below:

    In the event of a "Change of Control" (as defined in the Exchangeable
Debentures) with respect to the Company, each holder of the Exchangeable
Debentures has the right (a "Repurchase Right") to require the Company to
repurchase all or a portion of such holder's Exchangeable Debentures at a price
equal to 100% of the principal amount thereof plus accrued and unpaid interest;
provided, if for five Trading Days (as defined in the Exchangeable Debenture
Indenture) within the period of ten consecutive Trading Days ending immediately
before the "Change of Control" occurs, the Market Price (as defined in the
Exchangeable Debenture Indenture) of NutraMax Common Stock is at least equal to
105% of the then effective Exchange Rate (as defined in the Exchangeable
Debenture Indenture), no holder will be entitled to exercise such repurchase
right.
    
 
   
    A holder of an Exchangeable Debenture may exchange such Exchangeable
Debenture into shares of NutraMax Common Stock at any time before the close of
business on July 15, 2003. If the Exchangeable Debentures are called for
redemption, the holder may exchange its Exchangeable Debentures at any time
before the close of business on the tenth day prior to the date fixed for such
redemption. The current exchange rate is 65.3595 shares of NutraMax Common Stock
for each $1,000 principal amount of Exchangeable Debentures, subject to
adjustment; provided that the Company may, in lieu of delivering shares of
NutraMax Common Stock in exchange for the Exchangeable Debentures, elect to pay
the holder thereof an amount in cash equal to the Market Price of such shares of
NutraMax Common Stock into which the Exchangeable Debentures (or any portion
thereof) are exchangeable, plus any cash and other property theretofore
apportioned to such shares of NutraMax Common Stock.
    
 
   
    Pursuant to an Escrow Agreement dated as of July 30, 1993 between the
Company and First Fidelity, 2,254,902 shares of NutraMax Common Stock were
deposited by the Company in escrow with First Fidelity in support of the
Company's exchange obligations under the Exchangeable Debentures. On December
31, 1996, the Company sold to NutraMax all of the shares of NutraMax Common
Stock owned by the Company pursuant to an agreement under which the Company
received cash and an interest bearing note secured by a letter of credit. In the
event the Exchangeable Debentures are exchanged into shares of NutraMax Common
Stock, the amount of the note, which as of December 31, 1997 was $5.9 million,
will be reduced on a pro rata basis. The note is payable when the shares of
NutraMax Common Stock held in escrow in support of the Exchangeable Debentures
are delivered to NutraMax upon release from escrow. The shares of NutraMax
Common Stock are to be released from escrow upon the purchase or redemption of
Exchangeable Debentures by the Company.
    
 
   
    The consummation of the Merger will constitute a "Change of Control" for
purposes of the Exchangeable Debenture Indenture, and the Company is obligated,
within 20 days of such "Change of Control," to notify holders of Exchangeable
Debentures of their Repurchase Rights. See "RISK FACTORS--Required Offer to
Purchase Exchangeable Debentures."

                SECURITY OWNERSHIP IN THE SURVIVING CORPORATION
 
   
    The following table sets forth certain information with respect to the
presently anticipated beneficial ownership of the securities of the Surviving
Corporation immediately following consummation of the Merger. The amounts set
forth below assume an overall Equity Contribution of $109.5 million by the
Investors, of which $74.5, $20.0 and $15.0 million are assumed to have been
provided by BRS, FFT and Galen, respectively, and an overall Management
Investment of $4.2 million. Such amounts do not reflect the issuance of
additional shares of Surviving Corporation Common Stock which may be purchased
by certain persons after the Effective Time or the issuance of any options to
acquire securities of the Surviving Corporation which may be granted to the
employees of the Company. See "SPECIAL FACTORS-- Interests of Certain Persons in
the Merger." FFT and Galen have committed to an affiliate of BRS to invest up to
$30.0 and $20.0 million, respectively, in securities of the Surviving
Corporation. The amount of such investments, together with the investment by the
BRS Holders, shall be determined by BRS, but the investments by FFT and Galen
shall in no event be less than $20.0 and $15.0 million, respectively. See
"SOURCES AND AMOUNT OF FUNDS--Equity Contribution." The amounts included in the
table below represent the minimum investment by FFT and Galen. The actual
investments by BRS, FFT, Galen and the Management Stockholders have not been
definitively determined by BRS and remain subject to change.

             PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
 
   
    The following unaudited pro forma condensed consolidated financial
statements (the "Pro Forma Financial Statements") have been based on the
historical consolidated financial statements of the Company, SpectraCair and CH
Medical. The SpectraCair Acquisition was consummated on September 1, 1997, and,
accordingly, the Company's historical balance sheet at December 31, 1997
includes the assets and liabilities of SpectraCair and the Company's historical
consolidated statements of operations include the results of operations of
SpectraCair beginning September 1, 1997. The Company has entered into a
definitive agreement with respect to the CHI Acquisition and presently expects
to consummate this transaction either simultaneously with or shortly after the
Merger, subject to the satisfaction of certain conditions. There can be no
assurance, however, that the CHI Acquisition will be consummated. See "THE
COMPANY--CHI Acquisition."
    
 
   
    As a result of the SpectraCair Acquisition on September 1, 1997, the Company
anticipates the elimination of duplicative costs for functional areas and the
reduction of certain expenses as a result of expected synergies of $445,000. In
addition, SpectraCair recognized a charge in its statement of operations for the
eleven months ended August 31, 1997 of $573,000 related to the revenue generated
in fiscal 1996 from its acquisition of the rental assets of Bio Clinic
Corporation, a subsidiary of Sunrise Medical, Inc. on January 31, 1996. The Pro
Forma Financial Statements do not reflect the elimination of the above noted
items.
    
 
   
    The CH Medical historical financial information reflected in the Pro Forma
Financial Statements represent the accounts and operations of CH Medical with
respect to the CH Medical Business. During the period covered by the CH Medical
Financial Statements, the CH Medical Business was conducted as an integral part
of CHI's overall operations, and separate financial statements were not
prepared. The Company has been advised by CHI that the CH Medical Financial
Statements were prepared from the historical accounting records of CHI and
include various allocations for costs and expenses. Therefore, the statements of
operations of CH Medical may not be indicative of the results of operations that
would have resulted if CH Medical had operated on a stand alone basis. The
Company has been advised by CHI that all of the allocations and estimates
reflected in the CH Medical Financial Statements are based on assumptions that
CHI management believes are reasonable under the circumstances.
    
 
   
    Management expects that the CHI Acquisition will generate certain synergies
and result in a lower cost structure for the combined entity. Certain
anticipated cost savings for the closing of duplicate facilities and the
elimination of personnel are reflected in the Pro Forma Financial Statements.
Although management also anticipates that there will be additional cost savings
from the CHI Acquisition in such areas as insurance, advertising, and telephone
costs, travel, meals and entertainment expenses and taxes other than income,
such additional cost savings are not reflected in the Pro Forma Financial
Statements. Management estimates that such additional cost savings will
approximate $1.8 million per year. However, there can be no assurance that the
Company will be able to generate the expected cost savings.
    
 
   
    The pro forma condensed consolidated balance sheet gives effect to the
Transactions and, where applicable, the CHI Acquisition as if they were
consummated on December 31, 1997. The pro forma condensed consolidated
statements of operations give effect to the Transactions, the SpectraCair
Acquisition in fiscal 1997 and, where applicable, the CHI Acquisition as if they
were all consummated on October 1, 1996. The pro forma adjustments are described
more fully in the accompanying notes.
    
 
   
    The Pro Forma Financial Statements are presented for informational purposes
only and do not purport to be indicative of the results of operations that
actually would have been achieved had such transactions been consummated on the
date or for the periods indicated and do not purport to be indicative of the
balance sheet data or results of operations as of any future date or for any
future period. The Pro Forma Financial Statements should be read in conjunction
with the Company's Annual Report on Form 10-K for the year ended September 30,
1997, as amended, the Company's Quarterly Report on Form 10-Q for the quarter
ended December 31, 1997, the Consolidated Financial Statements of the
    
 
                                       77
<PAGE>
   
Company and related notes thereto, the financial statements with respect to the
CH Medical Business filed as Exhibit 99.8 to the Registration Statement, and the
other financial information contained in the documents included or incorporated
by reference herein. See "INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE."
    
 
   
    The pro forma adjustments were applied to the respective historical
statements to reflect and account for the Merger as a recapitalization.
Accordingly, the historical basis of the Company's assets and liabilities has
not been affected by the Merger. The acquisition of SpectraCair was and the CHI
Acquisition, if consummated, will be accounted for using the purchase method of
accounting. The purchase method of accounting allocates the aggregate purchase
price to the assets acquired and liabilities assumed based upon their respective
fair values. The allocation of the aggregate purchase price for the CH Medical
Business reflected in the Pro Forma Financial Statements is preliminary. The
final allocation of the aggregate purchase price is contingent upon studies and
valuations which have not yet been completed. Management is unable to predict
whether any adjustments as a result of the foregoing will have a material effect
on the Pro Forma Financial Statements.

(A) Reflects the elimination of transactions between the Company and SpectraCair
    for logistical services, and the elimination of the Company's portion of
    SpectraCair's historical loss, which the Company recognized on the equity
    method of accounting.
 
(B) Reflects the effect on income tax expense of the historical loss of
    SpectraCair and the pro forma adjustments described in the footnotes herein
    at an incremental effective tax rate of 40%. Prior to the September 1, 1997
    acquisition of SpectraCair, SpectraCair was a limited liability company and,
    therefore, was not subject to income taxes.
 
   
(C) Reflects the $1.0 million annual management fee pursuant to the Management
    Agreement. See "SPECIAL FACTORS--Interests of Certain Persons in the

    The Revolving Credit Facility is assumed to bear interest at an annual rate
    of LIBOR plus margins of 2.25% on amounts borrowed; bear interest at 2.25%
    for amounts reserved for letters of credit; and bear a fee of .5% for the
    undrawn portion of the unused commitments. Interest on the Revolving Credit
    Facility principally represents commitment fees on the undrawn portion of
    the commitments and the amount reserved for letters of credit. The Term
    Loans are assumed to bear interest at an annual rate of LIBOR plus 2.75%.
    The Company will pay a commitment fee of .5% per annum on the amount of
    unused commitments for Acquisition Loans. Interest on the Acquisition Loans
    represents commitment fees on $75.0 million of unused commitments. Under the
    Term Loan Facility, $100.0 million was assumed to be utilized to consummate
    the Transactions. If the CHI Acquisition is consummated, an additional $50.0
    million of Term Loans are expected to be utilized to acquire the CH Medical
    Business (see footnote E). Should the CHI Acquisition not be consummated
    simultaneously with the Merger, the Company will pay a commitment fee of .5%
    per annum on $50.0 million of the unused commitments under the Term Loan
    Facility from the date of the Merger until such commitments expire and
    interest on the Term Loans noted above would increase by a corresponding
    amount.

    LIBOR is based on the Company's average LIBOR rate for fiscal 1997 of 5.84%.
    The Discount Debentures and the Senior Subordinated Notes are assumed to
    bear interest at 12% and 9.5%, respectively. A 0.125% change in the interest
    rate on the above loans would increase or decrease annual interest expense

    Deferred financing fees on the New Credit Facility are allocated between the
    tranches based on each tranche's relative value to the total facility.
    Amortization periods for deferred financing fees related to the Revolving
    Credit Facility and the Acquisition Loans are six years and eight years for
    the Term Loans. Debt issue costs on the Discount Debentures and the Senior
    Subordinated Notes are amortized over eleven and ten years, respectively.
    
 
   
(E) The following unaudited pro forma statement of operations has been based on
    the CH Medical Financial Statements for the year ended August 31, 1997 filed
    as Exhibit 99.8 to the Registration Statement. The pro forma statement of
    operations is based on management's best estimate of the effects of the CHI
    Acquisition as if such acquisition had occurred on October 1, 1996 and the
    initial financing thereof. The pro forma statement of operations may not be
    indicative of the results of operations that actually would have been
    achieved had the CHI Acquisition been consummated on October 1, 1996.

    The Revolving Credit Facility is assumed to bear interest at an annual rate
    of LIBOR plus margins of 2.25% on amounts borrowed; bear interest at 2.25%
    for amounts reserved for letters of credit; and bear a fee of .5% for the
    undrawn portion of the unused commitments. Interest on the Revolving Credit
    Facility principally represents commitment fees on the undrawn portion of
    the commitments and the amount reserved for letters of credit. The Term
    Loans are assumed to bear interest at an annual rate of LIBOR plus 2.75%.
    The Company will pay a commitment fee of .5% per annum on the amount of
    unused commitments for Acquisition Loans. Interest on Acquisition Loans
    represent commitment fees on $75.0 million of unused commitments. Under the
    Term Loan Facility, $100.0 million was assumed to be utilized to consummate
    the Transactions. If the CHI Acquisition is consummated, an additional $50.0
    million of Term Loans are expected to be utilized to acquire the CH Medical
    Business (see footnote D). Should the CHI Acquisition not be consummated
    simultaneously with the Merger, the Company will pay a commitment fee of .5%
    per annum on $50.0 million of the unused commitments under the Term Loan
    Facility from the date of the Merger until such commitments expire and
    interest on the Term Loans noted above would increase by a corresponding
    amount. LIBOR is based on the Company's average LIBOR rate for fiscal 1997
    of 5.84%. The Discount Debentures and the Senior Subordinated Notes are
    assumed to bear interest at 12% and 9.5%, respectively. A 0.125% change in
    the interest rate on the above loans would increase or decrease quarterly
    interest expense and loss from continuing operations by:

    Deferred financing fees on the New Credit Facility are allocated between the
    tranches based on each tranche's relative value to the total facility.
    Amortization periods for deferred financing fees related to the Revolving
    Credit Facility and the Acquisition Loans are six years and eight years for
    the Term Loans. Debt issue costs on the Discount Debentures and the Senior
    Subordinated Notes are amortized over eleven and ten years, respectively.

    The pro forma statement of operations is based on management's best estimate
    of the effects of the CHI Acquisition as if such acquisition had occurred on
    October 1, 1996 and the initial financing thereof. The pro forma statement
    of operations may not be indicative of the results of operations that

    Taxes were calculated at an incremental effective tax rate of 40%. Of the
    $5,491 of total taxes, $2,636 of the tax effect of the above transactions
    were used to increase the Company's income tax receivable reflected in Other
    Current Assets. Such amount represents the Company's historical fiscal 1997
    income tax liability. The remainder of the tax effect of $2,855 is reflected
    in Deferred Income Taxes and Other Liabilities.
 
   
(J) On December 31, 1996, the Company sold to NutraMax all of the shares of
    NutraMax common stock owned by the Company at a price of $9.00 per share.
    Under the terms of the agreement the Company received from NutraMax cash and
    an interest bearing promissory note. The note is payable when NutraMax
    shares owned by the Company, which currently are held in escrow in support
    of the Company's 7.50% Exchangeable Debentures are released from that
    escrow. Upon consummation of the Merger, the holders of Exchangeable
    Debentures may require the Company to repurchase them. See "RISK FACTORS--
    Required Offer to Purchase Exchangeable Debentures" and "DESCRIPTION OF
    CERTAIN INDEBTEDNESS."
    
 
   
(K) The following unaudited pro forma statement of net investment in assets has
    been based on the CH Medical Financial Statements as of and for the three
    months ended November 30, 1997. The pro forma statement of net investment in
    assets is based on management's best estimate of the effects of the CHI
    Acquisition and the initial financing thereof. The CHI Acquisition will be
    accounted for using the purchase method of accounting whereby the aggregate
    purchase price will be allocated to the assets acquired and liabilities
    assumed based upon their respective fair values. The allocation of the
    aggregate purchase price reflected below is preliminary. The final
    allocation of the purchase price is contingent upon studies and valuations
    which have not yet been completed. Management is unable to predict whether
    any adjustment as a result of the foregoing will have a material effect.

                                  THE COMPANY
 
    The Company, through its wholly-owned subsidiary, MEDIQ/PRN, operates the
largest critical care, life support and movable medical equipment rental
business in the United States. Through its national distribution network, the
Company serves more than 5,000 hospitals, alternate care and home care
providers, nursing homes and other health care providers nationwide. The Company
rents over 650 different types of critical care, life support and other movable
medical equipment ("Medical Equipment"), including adult and infant ventilators,
adult, infant, neonatal and fetal monitors, infusion and suction pumps,
incubators, infant warmers, pulse oximeters, sequential compression devices and
oxygen concentrators. The Company also rents therapeutic support surfaces,
overlays and mattresses ("Support Surfaces").
 
    In addition to its core rental business, the Company sells a variety of
disposable products, accessories and repair parts primarily used with the types
of Medical Equipment it rents ("Disposables and Parts"). In addition, the
Company provides several outsourcing services to health care providers. The
Company's outsourcing services and sales of Disposables and Parts are natural
complements to the Company's core rental business, and enable the Company to
generate incremental revenues within an existing customer relationship as well
as leverage the Company's extensive distribution network and broad customer
base.
 
    The Company believes that rentals of Medical Equipment and Support Surfaces
and outsourcing of non-core functions of hospitals and other health care
providers have benefited from certain industry trends. In recent years,
hospitals have faced increasing pressure to reduce operating costs and capital
expenditures, while continuing to offer state-of-the-art health care. Equipment
rental programs can be more cost effective than the purchase or lease of movable
medical equipment because they enable health care providers to incur the cost
for equipment only when demand for such equipment exists, thus increasing the
providers' equipment utilization rates and decreasing their overall cost
structure. Additionally, by shifting the management of activities such as asset
management and repair and maintenance to third parties, hospitals and other
health care providers can reduce operating costs, increase efficiency and/ or
minimize technological obsolescence of equipment. As a result, the Company
believes that demand for medical equipment rentals and outsourcing services is
growing.
 
    In fiscal 1997, rental revenue accounted for approximately 80% of the
Company's revenues, sales of Disposables and Parts accounted for approximately
13% of the Company's revenues and the provision of Outsourcing Services (as
defined) accounted for approximately 7% of the Company's revenues.
 
RENTALS
 
   
    In its rental business, the Company rents its approximately 132,000 unit
Medical Equipment inventory to customers through 84 branch locations in major
metropolitan areas nationwide. Such locations operate 24 hours a day, 365 days a
year, with deliveries of patient-ready equipment typically made to customers
within two hours of a request. The Company's customers receive a full range of
rental and related services, including equipment delivery, inspection,
maintenance, repair and documentation. In September 1997, the Company
consummated the SpectraCair Acquisition in order to broaden its equipment rental
product lines to include rentals of Support Surfaces.
    
 
    In addition to standard rentals, the Company has entered into several
revenue-share arrangements with original equipment manufacturers ("OEMs")
pursuant to which the Company rents Medical Equipment and sells disposable
products produced by the OEMs to the Company's customers. Because the OEMs own
the equipment, such arrangements permit the Company to generate additional
revenues without any additional capital investment. In fiscal 1997, the Company
began to focus its efforts on increasing revenue sharing rental revenues as it
believes there are significant growth opportunities in this area.

<PAGE>
DISPOSABLES AND PARTS
 
    The Company sells a variety of Disposables and Parts to its customers,
primarily for use with the types of Medical Equipment it rents. The sales of
such Disposables and Parts are a natural complement to the Company's Medical
Equipment rental business. The Company distributes products to its existing
rental customers in order to enable them to fill smaller turnaround needs more
quickly and to smaller health care providers which do not meet the minimum order
requirements of the major medical supply distributors. The Company currently
supplies 4,000 disposable products primarily through contracted, centralized
distribution centers located in Salt Lake City, Utah and Pennsauken, New Jersey.
The Company also sells repair parts to its clients for the repair of their owned
equipment.
 
OUTSOURCING
 
    To address the needs of hospitals and other health care providers to better
manage their assets and increase profits, the Company also offers its customers
the following services, none of which require substantial capital investment by
the Company: (i) a Comprehensive Asset Management Program
(CAMP-Registered Trademark-, hereinafter "CAMP") which analyzes the critical
care equipment activity of a customer and provides a variety of logistics and
outsourcing services designed to manage, track and service the customer's
movable medical equipment; (ii) a biomedical repair service which provides
safety inspections, preventive maintenance and repairs for most critical care
equipment through a team of more than 170 experienced biomedical technicians;
(iii) a logistics and distribution service to assist equipment manufacturers in
reducing their transportation costs through utilization of the Company's
nationwide branch office network; (iv) a medical gas supply program designed to
complement the Company's respiratory equipment rentals and provide "one-stop"
service to health care providers in a fragmented market; and (v) a health care
consulting and management service designed to assist the Company's customers in
the management of their businesses (collectively, the "Outsourcing Services").
 
GROWTH STRATEGY
 
   
    In order to take full advantage of its market leadership and national
distribution network, the Company has introduced new services for its customers
and is pursuing strategic acquisition candidates. The following are the primary
elements of the Company's growth strategy.
    
 
    GROW CORE RENTAL BUSINESS.  The Company expects that certain regulatory and
industry trends will cause an increase in overall demand for equipment rentals.
The Company believes that it will be able to take advantage of these industry
trends and grow its core rental revenues by (i) capitalizing on its national
customer base, which the Company believes is the largest in the industry; (ii)
focusing on sub-acute and long term health care providers which have begun to
face pressure to reduce operating costs; (iii) identifying incremental rental
opportunities through its CAMP programs as it increases the number of hospitals
under CAMP contracts; (iv) increasing revenue sharing opportunities with rental
equipment manufacturers; and (v) continuing to market and grow SpectraCair as a
clinically efficient lower cost alternative to specialty beds.
 
    LEVERAGE INFRASTRUCTURE TO INCREASE REVENUES IN NON-CAPITAL INTENSIVE
BUSINESSES.  Because the Company's national distribution network has the most
expansive geographic coverage and broadest product line in its industry, the
Company believes that it can increase revenues in certain non-capital intensive
businesses by leveraging its infrastructure. In particular, the Company expects
to expand its marketing of Outsourcing Services, revenue sharing activities and
Disposables and Parts to its existing rental customer base. Moreover, the
Company plans to utilize its established distribution channels to develop these
businesses without incurring significant incremental costs. The Company believes
that leveraging its infrastructure to develop these businesses will produce an
increased return on assets, as these businesses require relatively low levels of
capital investment.
 
                                       94
<PAGE>
   
    FOCUS ON DEVELOPING ASSET MANAGEMENT PROGRAMS.  The Company believes that
its CAMP programs will continue to grow as a result of increasing competitive
pressure facing health care providers. Health care providers that have adopted
CAMP have been able to achieve cost savings through a reduction of biomedical
and other hospital staff, a decrease in equipment maintenance expenses and an
increase in asset utilization rates. Additionally, they have been able to
capture increased patient charges as a result of the superior information
gathering capability of CAMP. While most acute care facilities can benefit from
more efficient equipment management, the typical CAMP profile is 200 beds or
more and often part of an integrated network. Hospitals under CAMP contracts
increased from three as of December 31, 1996, to 15 as of December 31, 1997.
    
 
    ENTER INTO STRATEGIC PARTNERSHIPS.  The Company has and will continue to
seek new strategic partnerships to increase revenues. In biomedical repair, the
Company plans to increase revenues by partnering with equipment manufacturers to
provide biomedical repair services for their equipment. In December 1997, the
Company entered into an agreement with Siemens Medical Systems, Inc. USA
("Siemens"), a leading provider of medical equipment, to jointly provide
biomedical repair services to hospitals and other health care providers. The
Company estimates that the total biomedical repair market was $500 million in
1997 and believes that strategic partnerships such as the Siemens relationship
will provide continued growth opportunities. Earlier in 1997 the Company entered
into a contract with KCI New Technologies, Inc. ("NewTech") to be the exclusive
rental source of circulatory foot pumps manufactured by NewTech and the
exclusive distributor of related disposables, and in 1996 the Company entered
into a contract with Siemens to be the exclusive distributor of certain Siemens
accessories and parts.
 
   
    PURSUE STRATEGIC ACQUISITIONS.  The Company has demonstrated expertise in
integrating acquired medical equipment rental companies. The Company has
historically acquired complementary companies and integrated them effectively
into its existing operations. Since September 30, 1994, the Company has
consummated three acquisitions which, together with internal growth, have
resulted in an increase in revenues from $81.5 million in fiscal 1994 to $164.3
million on a pro forma basis in fiscal 1997. The Company has been able to
successfully complete and integrate these acquisitions by adhering to an
acquisition strategy which primarily focuses on acquisitions that (i) present a
relatively low level of integration risk, (ii) allow the Company to effectively
leverage its national distribution network, (iii) are complementary to the
Company's lines of business and (iv) have identifiable synergies. The Company
intends to continue to pursue acquisitions that it believes are consistent with
this acquisition strategy as well as its overall growth strategy. In addition to
the CHI Acquisition discussed below, the Company has entered into a non-binding
letter of intent with respect to another potential acquisition.
    
 
   
CHI ACQUISITION
    
 
   
    As part of its acquisition strategy, on April       , 1998, MEDIQ/PRN
entered into an Asset Purchase Agreement (the "Asset Purchase Agreement") with
the Sellers to purchase the CH Medical Business, which consists of certain of
the assets and rights of the Sellers including, but not limited to, inventory,
rental equipment and other tangible property, intellectual property rights, key
records (including customer lists, customer files, supplier information) and
certain contract rights, for a purchase price of approximately $50.0 million in
cash, including related costs and expenses, and the assumption of certain
specified obligations related to the acquired assets.
    
 
   
    CHI is a Texas-based corporation which has specialized in the development of
various medical products utilized in patient care treatment and therapy for over
thirty years. In addition to its development of medical products, CHI is a
national sales, rental and service corporation specializing in patient beds,
overlays, mattress replacement systems, pressure relieving pads and surfaces and
other therapeutic support surfaces with approximately 75 business locations
nationwide. CHI has, among other things, developed technology used in the
manufacture of beds and frameless systems for hospitals, extended care
facilities and homes to effectively treat the severe conditions and
complications inherent to patients who are bed confined. CHI offers a complete
line of portable pressure relieving products to provide hospitals and
    
 
                                       95
<PAGE>
   
extended care facilities with an array of bed therapies in a cost effective
manner. The assets acquired under the Asset Purchase Agreement involve only the
Sellers' assets related to the manufacture, sales and rental of beds and other
support surfaces and do not include the Sellers' other fabrication businesses.
    
 
   
    The obligations of MEDIQ/PRN under the Asset Purchase Agreement are
conditioned upon receipt of all statutory and regulatory consents and approvals
under the laws or regulations of the United States necessary to permit the
consummation of the acquisition and necessary to own and operate the acquired
assets, including approval under the HSR Act. Accordingly, on April 2, 1998,
MEDIQ/PRN and the Sellers each filed a notification report together with
requests for early termination of the waiting period under the HSR Act with the
FTC and the Antitrust Division in respect of the transaction and on April 13,
1998, the FTC and the Antitrust Division granted early termination of the
waiting period under the HSR Act in respect of the transaction. In addition to
approval under the HSR Act, the obligations of MEDIQ/PRN under the Asset
Purchase Agreement are also subject to, among other things, the fulfillment or
waiver of the following conditions:
    
 
   
    (a) The representations and warranties made by the Sellers and qualified by
the words "material" or "material adverse effect" or like words shall be true
and correct, and the representations and warranties not so qualified shall be
true in all material respects as of the closing.
    
 
   
    (b) The Sellers shall have performed and complied with all covenants,
agreements, and conditions required by the Asset Purchase Agreement to be
performed or complied with by them prior to or at the closing.
    
 
   
    (c) The consents necessary or advisable to transfer the acquired assets and
for MEDIQ/PRN to operate the business from and after the closing shall have been
secured in a form reasonably satisfactory to MEDIQ/PRN.
    
 
   
    (d) There shall not have been any material adverse effect in respect of the
acquired assets or the acquired business prior to the closing.
    
 
   
    (e) All of the liens and other encumbrances (excluding certain permitted
exceptions) outstanding on any of the acquired assets shall have been terminated
and released prior to or at the closing.
    
 
   
    (f) There shall not be any order of any court or administrative agency in
effect which restrains or prohibits the transactions contemplated by the Asset
Purchase Agreement or which would materially limit or adversely affect
MEDIQ/PRN's ownership or control of any of the acquired assets or the acquired
business, and there shall not have been threatened, nor shall there be pending,
any action or proceeding by or before any court or governmental agency or other
regulatory or administrative agency or commission, (i) challenging any of the
transactions contemplated by the Asset Purchase Agreement or seeking monetary
relief by reason of the consummation of such transactions or (ii) which might
have a material adverse effect on the acquired assets or on the business,
prospects or condition (financial or otherwise) of the Sellers.
    
 
   
    (g) MEDIQ/PRN shall have completed arrangements for the financing of the
purchase of the acquired assets on terms and conditions to MEDIQ/PRN's sole
satisfaction and it shall have received the proceeds thereof.
    
 
   
    All obligations of the Sellers under the Asset Purchase Agreement are
subject to, among other things, the fulfillment or waiver prior to or at the
closing, of the following conditions.
    
 
   
    (a) The representations and warranties made by MEDIQ/PRN in the Asset
Purchase Agreement and qualified by the words "material" or "material adverse
effect" or like words shall be true and correct, and the representations and
warranties not so qualified shall be true in all material respects as of the
closing.
    
 
                                       96
<PAGE>
   
    (b) MEDIQ/PRN shall have performed and complied with all covenants,
agreements and conditions required by the Asset Purchase Agreement to be
performed or complied with by it prior to or at the closing.
    
 
   
    In addition to the foregoing, the Asset Purchase Agreement contains certain
covenants by the Sellers relating to conduct of the business prior to the
effective time; corporate name changes after the effective time; cooperation;
obtaining of necessary consents; confidential information; no solicitation of
alternative transactions; and non-competition provisions. The Asset Purchase
Agreement also contains covenants made by MEDIQ/PRN relating to cooperation and
employee hiring and other employee related matters.
    
 
   
    It is anticipated that the closing of the CHI Acquisition will take place on
the date not later than the latest to occur of (i) 5 days after the closing of
the Merger or (ii) 5 days after the satisfaction or waiver of all conditions to
the closing, but in no event later than       1998. The consummation of the
Merger is not conditioned upon the closing of the CHI Acquisition, and the CHI
Acquisition is not conditioned upon the consummation of the Merger.
    
 
   
    There can be no assurance that the Company will ultimately consummate the
CHI Acquisition or that, if consummated, the terms of the CHI Acquisition will
be as described herein. The Company presently expects to finance the purchase
price of the CHI Acquisition with $50.0 million of Term Loans under the New
Credit Facility. See "SOURCES AND AMOUNT OF FUNDS." There can be no assurance
that the Company will be able to effectively integrate the CHI Acquisition into
its existing operations. In addition to the CHI Acquisition, the Company is also
continually reviewing other potential acquisition opportunities. There can be no
assurance that the Company will ultimately consummate any other such potential
acquisitions.
    
 
STOCKHOLDER LITIGATION
 
   
    On January 15, 1998, Crandon Capital Partners, a stockholder of the Company,
sued the Company and each of the Company's directors in Delaware Chancery Court,
alleging breaches of fiduciary duties in connection with the directors' approval
of the Merger and the related transactions. The complaint purports to be a class
action complaint and plaintiff seeks to enjoin the Merger or, in the
alternative, to recover compensatory damages. The Company believes that this
claim is completely without merit and does not have a reasonable likelihood of
success. The Company and the directors of the Company intend to vigorously
defend the action. A copy of the complaint was filed as Exhibit 99.2 to the
Company's Current Report on Form 8-K filed with the Commission on January 21,
1998 and is hereby incorporated herein by reference.
    
 
   
    It is a condition to the Company's and MQ's obligations to consummate the
Merger that there be no material litigation pending by a governmental entity (or
by any other person, which has a reasonable likelihood of success) seeking to
enjoin or otherwise prevent the Merger. The Company and MQ presently believe
that this claim is without merit and does not have a reasonable likelihood of
success and accordingly do not expect that the existence of this claim will
relieve the Company or MQ of its obligation under the Merger Agreement to
consummate the Merger although each of the Company and MQ has reserved its
rights under the Merger Agreement in respect of such matter.
    
 
    Based on information currently available to it, the Company believes that
resolution of the claim will not have a material adverse effect on the operation
or financial condition of the Company.
 
             DESCRIPTION OF MEDIQ CAPITAL STOCK PRIOR TO THE MERGER
 
GENERAL
 
    The Company is authorized by its Certificate of Incorporation, as amended,
to issue an aggregate of 40,000,000 shares of Common Stock, par value $1.00 per

The following is a summary of certain of the rights and privileges
 
                                       97
<PAGE>
pertaining to the MEDIQ Stock. For a full description of the MEDIQ Stock,
reference is made to the Company's Certificate of Incorporation, as amended,
which has been filed as an exhibit to the Registration Statement.
 
    The Merger and the Merger Agreement require for the approval thereof, (i)
the affirmative vote of the holders of a majority of the outstanding voting
power of the MEDIQ Shares, voting together as a single class and (ii) the
affirmative vote of the holders of a majority of the outstanding MEDIQ Preferred
Shares.
 
MEDIQ COMMON STOCK
 
   
    The holders of MEDIQ Common Stock are entitled to one vote per share on all
matters submitted for action by the stockholders. As of the Record Date,
19,369,826 shares of MEDIQ Common Stock were issued and outstanding.
    
 
    There is no provision for cumulative voting with respect to the election of
directors. The MEDIQ Common Stock and MEDIQ Preferred Stock vote together as a
single class, except that pursuant to the Company's Certificate of
Incorporation, the nominees for director who are not officers or employees of
the Company ("Outside Directors") are to be elected solely by the holders of
MEDIQ Common Stock, voting as a separate class. Accordingly, the holders of more
than 50% of the shares of MEDIQ Common Stock can elect all of the Outside
Directors.
 
    Subject to the rights of any holders of outstanding MEDIQ Preferred Stock,
all shares of MEDIQ Common Stock are entitled to share in such dividends as the
Board of Directors may from time to time declare from sources legally available
therefor.
 
    Subject to the rights of any holders of outstanding MEDIQ Preferred Stock,
upon liquidation or dissolution of the Company, whether voluntary or
involuntary, all shares of MEDIQ Common Stock are entitled to share equally in
the assets or surplus funds available for distribution to stockholders after
payment of all prior obligations of the Company.
 
    No holder of MEDIQ Common Stock possesses any preemptive rights to subscribe
or acquire any unissued or capital stock of the Company (whether now or
hereafter authorized) or securities of the Company convertible into or carrying
a right to subscribe to or acquire shares of capital stock of the Company.
 
MEDIQ PREFERRED STOCK
 
   
    On matters subject to a vote by holders of the MEDIQ Common Stock, the
holders of the MEDIQ Preferred Stock are entitled to 10 votes for each share of
MEDIQ Preferred Stock held. Without the consent of the holders of at least
66 2/3% of the outstanding shares of MEDIQ Preferred Stock, voting as a separate
class, the Company may not amend, alter or repeal the Certificate of
Incorporation of the Company in any way that would adversely affect the
preferences rights or powers of the MEDIQ Preferred Stock, or authorize any
class of stock ranking senior to the MEDIQ Preferred Stock. Without the consent
of the holders of at least a majority of the outstanding shares of MEDIQ
Preferred Stock, voting as a separate class, the Company cannot merge with any
other corporation. As of the Record Date, 6,265,998 shares of MEDIQ Preferred
Stock were issued and outstanding.
    
 
   
    There is no provision for cumulative voting with respect to the election of
directors. The MEDIQ Common Stock and MEDIQ Preferred Stock vote together as a
single class, except that pursuant to the Company's Certificate of
Incorporation, the nominees for Outside Directors are to be elected solely by
the holders of MEDIQ Common Stock, voting as a separate class. Accordingly, the
holders of more than 65.5% of the shares of MEDIQ Preferred Stock can elect all
of the directors (other than Outside Directors).
    
 
                                       98
<PAGE>
   
    All shares of MEDIQ Preferred Stock are entitled to share in such dividends
as the Board of Directors may from time to time declare from sources legally
available therefor, subject to the following provisions: (i) all shares of MEDIQ
Preferred Stock are entitled to share in cash dividends at a rate of 60% of the
then-current rate of cash dividends payable on each share of MEDIQ Common Stock
and (ii) dividends of shares of MEDIQ Preferred Stock may be paid to holders of
MEDIQ Preferred Stock if a dividend of shares of MEDIQ Common Stock is paid
simultaneously to holders of MEDIQ Common Stock.
    
 
    Upon the liquidation or dissolution of the Company, whether voluntary or
involuntary, the holders of MEDIQ Preferred Stock will be entitled to receive
from assets of the Company available for distribution to its stockholders,
before any payment or distribution will be made on the MEDIQ Common Stock, an
amount equal to $.50 per share. If after payment to the holders of MEDIQ
Preferred Stock of the full preferential amounts provided for in the preceding
sentence, assets or surplus funds remain in the Company then the holders of
MEDIQ Preferred Stock will be entitled to share in all such remaining assets or
surplus funds in the same manner as if all shares of MEDIQ Preferred Stock had
been converted into MEDIQ Common Stock.
 
            DESCRIPTION OF MEDIQ CAPITAL STOCK FOLLOWING THE MERGER
 
GENERAL
 
    If the Merger is approved by the requisite vote of the stockholders of MEDIQ
Stock at the Special Meeting, at the Effective Time the Certificate of
Incorporation of the Surviving Corporation shall be amended as set forth on
Annex D. The following is a summary of certain of the rights and privileges
that, after the Effective Time, will pertain to the stock of the Surviving
Corporation. For a full description of such stock, reference is made to the
Certificate of Incorporation of the Surviving Corporation, as amended, a copy of
which is attached hereto as Annex D.
 
   
    The MEDIQ Common Stock and the MEDIQ Preferred Stock are currently listed on
the AMEX. It is MQ's present intention that, following the Merger, neither the
Series A Preferred Stock nor any other class or series of the Surviving
Corporation's capital stock will be listed on the AMEX or any other national
securities exchange and will not be quoted on the NASDAQ Stock Market, Inc.
Notwithstanding that the Surviving Corporation may not be required to remain
subject to the reporting requirements of Section 13 or 15(d) of the Exchange
Act, the Surviving Corporation will, for the two years following the Effective
Time, file with the Commission such reports as are specified in Section 13 and
15(d) of the Exchange Act and required to be filed in respect of securities
similar to the Series A Preferred Stock by issuers subject to the reporting
requirements of Section 13 of the Exchange Act, such reports to be so filed at
the times specified for the filings of such reports required under such
Sections; provided that the Surviving Corporation will have no obligation to
file such reports if fewer than 500,000 shares of Series A Preferred Stock
remain outstanding.
    
 
   
    In addition, the Bylaws of MQ as in effect at the Effective Time will be the
Bylaws of the Surviving Corporation until thereafter exchanged or amended
(subject to the restrictions set forth in the Merger Agreement) or by applicable
law.
    
 
COMMON STOCK
 
    Following the Merger, the Surviving Corporation will be authorized by its
Certificate of Incorporation, as amended, to issue an aggregate of 30,000,000
shares of the Surviving Corporation Common Stock.
 
    The holders of Surviving Corporation Common Stock will be entitled to one
vote per share on all matters submitted for action by the stockholders. There is
no provision for cumulative voting with respect to the election of directors.
Accordingly, the holders of more than 50% of the shares of Surviving Corporation
Common Stock will be able to elect all of the directors. In such event, the
holders of the
 
                                       99
<PAGE>
remaining shares will not be able to elect any directors. The Rotko Entities,
pursuant to the Rollover Agreement, will be entitled to designate one director
of the Surviving Corporation under certain circumstances. See "THE ROLLOVER
AGREEMENT."
 
    Subject to the rights of any holders of outstanding Surviving Corporation
Preferred Stock, all shares of Surviving Corporation Common Stock will be
entitled to share in such dividends as the Board of Directors may from time to
time declare from sources legally available therefor.
 
    Subject to the rights of any holders of outstanding Surviving Corporation
Preferred Stock, upon liquidation or dissolution of the Surviving Corporation,
whether voluntary or involuntary, all shares of Surviving Corporation Common
Stock are entitled to share equally in the assets available for distribution to
stockholders after payment of all prior obligations of the Surviving
Corporation.
 
PREFERRED STOCK
 
   
    Following the Merger, the Surviving Corporation will be authorized by its
Certificate of Incorporation, as amended, to issue an aggregate of 40,000,000
shares of Surviving Corporation Preferred Stock. The Board of Directors will
also be empowered under the Surviving Corporation's Certificate of Incorporation
and without further stockholder action to divide any and all shares of the
Surviving Corporation Preferred Stock into series and to fix and determine the
relative rights and preferences of the shares of any series so established. The
issuance of Surviving Corporation Preferred Stock by the Board of Directors
could affect the rights of holders of shares of Surviving Corporation Common
Stock. For example, issuance of Surviving Corporation Preferred Stock could
result in a class of securities outstanding that will have certain preferences
with respect to dividends and in liquidation over the Surviving Corporation
Common Stock, and may enjoy certain voting rights, contingent or otherwise, in
addition to that of the Surviving Corporation Common Stock, and could result in
the dilution of the voting rights, net income per share and net book value of
the Surviving Corporation Common Stock.
    
 
SERIES A PREFERRED STOCK
 
    GENERAL.  In connection with the Merger, each holder of MEDIQ Shares will
receive, in exchange for each MEDIQ Share, in addition to cash consideration of
$13.75 (without interest), 0.075 of a share of Series A Preferred Stock.
Pursuant to the Certificate of Designation to be filed with the Secretary of
State of Delaware with respect to the Series A Preferred Stock included in Annex
D hereto, 10,000,000 shares of Series A Preferred Stock, par value $.01, with a
liquidation value of $10.00 per share plus accrued and unpaid dividends will be
authorized for issuance. The Series A Preferred Stock will be, when issued,
fully paid and non-assessable and holders thereof will have no preemptive rights
in connection therewith. In connection with the Transactions, the Company
expects to issue approximately 7,830,000 shares of Series A Preferred Stock.
 
    The Series A Preferred Stock will not be listed on the AMEX or any other
securities exchange and will not be quoted on the NASDAQ, consequently, there
can be no assurance that any trading market will exist or develop for the Series
A Preferred Stock after the Merger. Shares of the Series A Preferred Stock would
trade only in the over-the-counter market. Although prices in respect of trades
would be published by the National Association of Securities Dealers, Inc.
periodically in the "pink sheets," quotes for such shares would not be readily
available. As a result, it is anticipated that the shares will trade much less
frequently relative to the trading volume of the Company's securities prior to
the Merger. At present there is no trading market for the Series A Preferred
Stock. There can be no assurance that holders will be able to sell their
securities at favorable prices or that the trading prices for the securities
will be comparable to the trading prices for MEDIQ Shares prior to consummation
of the Merger. A large number of securities may be traded by holders immediately
following completion of the Merger for various reasons. This might tend to
depress the market price of the Series A Preferred Stock.
 
                                      100
<PAGE>
   
    Although the stated value of the Series A Preferred Stock is set at its
liquidation value of $10.00 per share, the valuation of the Series A Preferred
Stock is subject to uncertainties and contingencies, all of which are difficult
to predict, and the stated value of the Series A Preferred Stock and the amounts
at which the Series A Preferred Stock is reflected in the pro forma financial
information contained herein are not necessarily reflective of the prices at
which the Series A Preferred Stock will actually trade at or after the time of
their issuance, whether before or after such securities are fully distributed.
The liquidity of and the market prices for the Series A Preferred Stock can be
expected to vary with changes in market and economic conditions, the financial
condition and prospects of the Surviving Corporation and other factors that
generally influence the market prices of securities, including in particular
further fluctuations in the market for high yield securities generally. Such
fluctuations in the high yield market may significantly affect liquidity and
market prices independent of the financial performance of and prospects for the
Surviving Corporation and its subsidiaries. In addition, the Series A Preferred
Stock may trade at prices that do not fully reflect the value of accrued but
undeclared dividends. The Board of Directors and the Special Committee, with the
assistance of the Company's financial advisor, attributed to the Series A
Preferred Stock a significant discount from its stated value. See "SPECIAL
FACTORS."
    
 
   
    RANK.  The Series A Preferred Stock will, with respect to dividend rights
and rights on liquidation, winding up and dissolution of the Surviving
Corporation, rank (a) senior to the Surviving Corporation Common Stock, the
Series B Preferred Stock, the Series C Preferred Stock, and each other class of
capital stock or class or series of preferred stock issued by the Company after
the Effective Date, the terms of which specifically provide that such class or
series will rank junior to the Series A Preferred Stock as to dividend
distributions or distributions upon the liquidation, winding up and dissolution
of the Surviving Corporation (collectively referred to as "Series A Junior
Securities"), (b) on a parity with each other class of capital stock or class or
series of preferred stock issued by the Surviving Corporation after the
Effective Date the terms of which do not specifically provide that they rank
junior to Series A Preferred Stock or senior to Series A Preferred Stock as to
dividend distributions or distributions upon liquidation, winding up and
dissolution of the Surviving Corporation (collectively referred to as "Series A
Parity Securities"), and (c) junior to each other class of capital stock or
other class or series of preferred stock issued by the Surviving Corporation
that by its terms is senior to the Series A Preferred Stock with respect to
dividend distributions or distributions upon the liquidation, winding up and
dissolution of the Surviving Corporation (collectively referred to as "Series A
Senior Securities").
    
 
   
    Although the Series A Preferred Stock will, with respect to dividend rights
and rights on liquidation, rank senior to Series A Junior Securities issued by
the Surviving Corporation, it will be junior in right of payment to all existing
and future indebtedness and obligations of the Surviving Corporation. The
lending facilities to which the Company will be a party will restrict payment of
cash dividends by the Surviving Corporation. See "RISK FACTORS--Restrictions on
the Payment of Dividends" and "SOURCES AND AMOUNT OF FUNDS."
    
 
    DIVIDENDS.  Each holder of Series A Preferred Stock will be entitled to
receive, when, as and if declared by the Board of Directors, out of funds
legally available therefor, cash dividends on each share of Series A Preferred
Stock at a rate equal to $1.30 per share per annum. All dividends will be
cumulative, whether or not earned or declared, and will accrue on a daily basis
from the date of issuance of Series A Preferred Stock, and will be payable
semi-annually in arrears on each dividend payment date, commencing on the second
dividend payment date after the date of issuance of such Series A Preferred
Stock. Each dividend on Series A Preferred Stock will be payable to the holders
of record of Series A Preferred Stock as they appear on the stock register of
the Surviving Corporation on such record date as may be fixed by the Board of
Directors, which record date will not be less than 10 nor more than 60 days
prior to the applicable dividend payment date. Dividends will cease to accrue in
respect of shares of Series A Preferred Stock on the date of their repurchase by
the Surviving Corporation unless the Surviving Corporation has failed to pay the
relevant repurchase price on the date fixed for repurchase. Notwithstanding
anything to the contrary set forth above, unless and until such dividends are
declared by the Board of Directors, there
 
                                      101

will be no obligation to pay such dividends; provided, that such dividends will
continue to cumulate and will be added to the Series A Liquidation Preference
(as defined herein) at the time of repurchase as provided herein if not earlier
declared and paid. Accrued dividends on the Series A Preferred Stock if not paid
on the first or any subsequent dividend payment date following accrual will
thereafter accrue additional dividends ("Additional Dividends") in respect
thereof, compounded annually, at the rate of 13.0% per annum. All dividends paid
with respect to shares of Series A Preferred Stock will be paid pro rata to the
holders entitled thereto.
    
 
    As long as any Series A Preferred Stock is outstanding, no dividends will be
declared by the Board of Directors or paid or funds set apart for the payment of
dividends or other distributions on any Series A Parity Securities for any
period, and no Series A Parity Securities may be repurchased, redeemed or
otherwise acquired, nor may funds be set apart for such payment (other than
dividends, other distributions, redemptions, repurchases or acquisitions payable
in Series A Junior Securities and cash in lieu of fractional shares of such
Series A Junior Securities in connection therewith), unless (i) full accumulated
dividends have been paid or set apart for such payment on the Series A Preferred
Stock and Series A Parity Securities for all Dividend Periods terminating on or
prior to the date of payment of such dividends or distributions on, or such
repurchase or redemption of, such Series A Parity Securities (the "Series A
Parity Payment Date") and (ii) any such dividends are declared and paid pro rata
so that the amounts of any dividends declared and paid per share on outstanding
Series A Preferred Stock and each other share of Series A Parity Securities will
in all cases bear to each other the same ratio that accrued and unpaid dividends
(including any accumulated dividends) per share of outstanding Series A
Preferred Stock and such other outstanding shares of Series A Parity Securities
bear to each other.
 
   
    The holders of Series A Preferred Stock will be entitled to receive the
dividends in preference to and in priority over any dividends upon any of the
Series A Junior Securities. Such dividends on the Series A Preferred Stock will
be cumulative, whether or not earned or declared, so that if at any time full
accumulated dividends on all shares of Series A Preferred Stock then outstanding
have not been paid or set aside for all Dividend Periods then elapsed, the
amount of such unpaid dividends will be paid before any sum will be set aside
for or applied by the Surviving Corporation to the purchase, redemption or other
acquisition for value of any shares of Series A Junior Securities (either
pursuant to any applicable sinking fund requirement or otherwise) or any
dividend or other distribution will be paid or declared and set apart for
payment on any Series A Junior Securities; provided, however, that the foregoing
will not (i) prohibit the Surviving Corporation from repurchasing shares of
Series A Junior Securities from a holder who is, or was, a director or employee
of the Surviving Corporation (or an affiliate of the Surviving Corporation) and
(ii) prohibit the Surviving Corporation from making dividends, other
distributions, redemptions, repurchases or acquisitions in respect of Series A
Junior Securities payable in Series A Junior Securities and paying cash in lieu
of fractional shares of such Series A Junior Securities in connection therewith.
    
 
    Dividends payable on Series A Preferred Stock for any period less than one
year will be computed on the basis of a 360-day year consisting of twelve 30-day
months and the actual number of days elapsed in the period for which such
dividends are payable.
 
   
    The additional indebtedness incurred by the Surviving Corporation in
connection with the Merger may have an adverse effect on the Surviving
Corporation's ability to declare and pay accrued dividends on the Series A
Preferred Stock or to redeem the Series A Preferred Stock. See "RISK FACTORS--
Substantial Leverage; Ability to Service Debt; Stockholders' Deficit."
    
 
    LIQUIDATION PREFERENCE.  Upon any voluntary or involuntary liquidation,
dissolution or winding up of the Company, the holders of all shares of Series A
Preferred Stock then outstanding will be entitled to be paid out of the assets
of the Surviving Corporation available for distribution to its stockholders an
amount in cash equal to $10.00 per share, plus an amount equal to full
cumulative dividends (whether or not earned or declared) accrued and unpaid
thereon, including Additional Dividends, to the date of final distribution (the
"Series A Liquidation Preference") and no more, before any distribution is made
on any
 
                                      102
<PAGE>
Series A Junior Securities. If upon any voluntary or involuntary liquidation,
dissolution or winding up of the Surviving Corporation, the application of all
amounts available for payments with respect to Series A Preferred Stock and all
other Series A Parity Securities would not result in payment in full of Series A
Preferred Stock and such other Series A Parity Securities, the holders and
holders of Series A Parity Securities will share equally and ratably in any
distribution of assets of the Surviving Corporation in proportion to the full
liquidation preference to which each is entitled. After payment in full in
accordance with the preceding sentence, the holders of the Series A Preferred
Stock shall not be entitled to any further participation in any distribution in
the event of liquidation, dissolution or winding up of the affairs of the
Surviving Corporation with respect to the shares of Series A Preferred Stock.
 
   
    OPTIONAL REDEMPTION.  The Surviving Corporation may, at its option, redeem
at any time or from time to time, from any source of funds legally available
therefor, in whole or in part any or all of the shares of Series A Preferred
Stock, at a redemption prices set forth below, plus an amount equal to full
cumulative dividends (whether or not earned or declared) accrued and unpaid
thereon, including Additional Dividends, to the redemption date. The redemption
price for optional redemptions are as follows:

    No partial redemption of Series A Preferred Stock may be authorized or made
unless prior thereto, full accrued and unpaid dividends thereon for all dividend
periods terminating on or prior to the redemption date and an amount equal to a
prorated dividend thereon for the period from the dividend payment date
immediately prior to the redemption date to the redemption date have been or
immediately prior to the redemption notice are declared and paid in cash or are
declared and there has been a sum set apart sufficient for such cash payment on
the redemption date.
 
    In the event of a redemption of only a portion of the then outstanding
shares of Series A Preferred Stock, the Surviving Corporation will effect such
redemption pro rata according to the number of shares held by each holder of
Series A Preferred Stock.
 
    MANDATORY REDEMPTION.  All outstanding shares of the Series A Preferred
Stock will be redeemed from funds legally available therefor on December 31,
2011, at a price per share equal to the Series A Liquidation Preference on
December 31, 2011.
 
    NOTICE OF REDEMPTION.  At least 30 days and not more than 60 days prior to
the date fixed for any redemption of Series A Preferred Stock, written notice
(the "Redemption Notice") will be given by first class mail, postage prepaid, to
each holder of record of Series A Preferred Stock on the record date fixed for
such redemption of Series A Preferred Stock at such holder's address as set
forth on the stock register of the Surviving Corporation on such record date. If
a Redemption Notice has been properly mailed, unless the Surviving Corporation
defaults in the payment in full of the redemption price, then, notwithstanding
that the certificates evidencing any shares of Series A Preferred Stock so
called for redemption have not been surrendered, (x) on the redemption date, the
shares represented thereby so called for redemption will be deemed no longer
outstanding and will have the status of authorized but unissued shares of
Surviving Corporation Preferred Stock, undesignated as to series, (y) dividends
with respect to the shares so called for redemption will cease to accrue after
the redemption date and (z) all rights with respect to the shares so called for
redemption or subject to conversion will forthwith after such date cease and
terminate, except for the right of the holders to receive the funds, if any,
payable without interest upon surrender of their certificates therefor.

    VOTING RIGHTS.  The holders of Series A Preferred Stock will not be entitled
or permitted to vote on any matter required or permitted to be voted upon by the
stockholders of the Surviving Corporation, except as otherwise required by
Delaware law except that, without the written consent of the holders of a
majority of the outstanding shares of Series A Preferred Stock or the vote of
the holders of a majority of the outstanding shares of Series A Preferred Stock
at a meeting of the holders of Series A Preferred Stock called for such purpose,
the Surviving Corporation will not (a) create, authorize or issue any other
class or series of stock entitled to a preference prior to Series A Preferred
Stock upon any dividend or distribution or any liquidation, distribution of
assets, dissolution or winding up of the Surviving Corporation, or (b) amend,
alter or repeal any provision of the Surviving Corporation's Certificate of
Incorporation so as to materially adversely affect the relative rights and
preferences of the Series A Preferred Stock. In any case in which the holders
will be entitled to vote, each holder of Series A Preferred Stock will be
entitled to one vote for each share of Series A Preferred Stock held unless
otherwise required by applicable law. Without limiting the generality of the
foregoing, in no event will the holders of Series A Preferred Stock be entitled
to vote (individually or as a class) on any merger or consolidation involving
the Surviving Corporation, any sale of all or substantially all of the assets of
the Surviving Corporation or any similar transaction. The Investors will,
immediately after the Effective Time, own a majority of the outstanding shares
of Series A Preferred Stock. In light of the foregoing, holders of Series A
Preferred Stock will have very limited voting rights compared to the voting
rights that such holders currently have with respect to their MEDIQ Common Stock
or MEDIQ Preferred Stock, as the case may be. See "DESCRIPTION OF MEDIQ CAPITAL
STOCK PRIOR TO THE MERGER."
 
    NO RIGHT OF CONVERSION OR EXCHANGE.  The holders of Series A Preferred Stock
will not have any rights hereunder to convert such shares into or exchange such
shares for shares of any other class or classes or of any other series of any
class or classes of capital stock of the Surviving Corporation.
 
    NO PREEMPTIVE RIGHTS.  No holder of Series A Preferred Stock will possess
any preemptive rights to subscribe or acquire any unissued shares of capital
stock of the Surviving Corporation (whether now or hereafter authorized) or
securities of the Surviving Corporation convertible into or carrying a right to
subscribe to or acquire shares of capital stock of the Surviving Corporation.
 
    Dividends, including dividends with respect to the Series A Preferred Stock,
can only be paid by the Surviving Corporation to the extent funds are legally
available therefor under the DGCL. See "RISK FACTORS--Restrictions on the
Payment of Dividends."
 
SERIES B PREFERRED STOCK
 
   
    GENERAL.  In connection with the Transactions, each Rotko Entity and certain
other persons (including the Investors and the Management Stockholders) will
receive shares of the Series B Preferred Stock of the Surviving Corporation.
Pursuant to the Certificate of Designation to be filed with the Secretary of
State of Delaware with respect to the Series B Preferred Stock included in Annex
D hereto, 5,000,000 shares of Series B Preferred Stock with a stated value of
$10.00 per share and a liquidation preference of $10.00 per share plus accrued
and unpaid dividends will be authorized for issuance. The Series B Preferred
Stock will be, when issued, fully paid and non-assessable and holders thereof
will have no preemptive rights in connection therewith.
    
 
    Neither the stated value nor the liquidation preference of the Series B
Preferred Stock is necessarily indicative of the actual value of the shares of
Series B Preferred Stock at or after the time of their issuance. The value of
the Series B Preferred Stock can be expected to fluctuate with changes in market
and economic conditions, the financial condition and prospects of the Company
and other factors that generally influence the value of securities.
 
    RANK.  The Series B Preferred Stock will, with respect to dividend rights
and rights on liquidation, winding up and dissolution of the Surviving
Corporation, rank junior to the Series A Preferred Stock and
 
                                      104
<PAGE>
senior to the Series C Preferred Stock as to dividend distributions or
distributions upon the liquidation, winding up and dissolution of the Surviving
Corporation.
 
   
    Although the Series B Preferred Stock will, with respect to dividend rights
and rights on liquidation, rank senior to Series C Preferred Stock issued by the
Surviving Corporation, it will be junior in right of payment to all existing and
future indebtedness and obligations of the Surviving Corporation. As described
in "SOURCES AND AMOUNT OF FUNDS," the lending facilities to which the Company
will be a party will restrict payment of cash dividends by the Surviving
Corporation.
    
 
    DIVIDENDS.  Each holder of Series B Preferred Stock will be entitled to
receive, when, as and if declared by the Board of Directors, out of funds
legally available therefor, cash dividends on each share of Series B Preferred
Stock at a rate equal to $1.325 per share per annum. All dividends will be
cumulative and compounding, whether or not earned or declared, and will accrue
on a daily basis from the date of issuance of Series B Preferred Stock, and will
be payable semi-annually in arrears.
 
   
    LIQUIDATION PREFERENCE.  Upon any voluntary or involuntary liquidation,
dissolution or winding up of the Surviving Corporation, the holders of all
shares of Series B Preferred Stock then outstanding will be entitled to be paid
out of the assets of the Surviving Corporation available for distribution to its
stockholders an amount in cash equal to $10.00 per share, plus an amount equal
to full cumulative dividends (whether or not earned or declared) accrued and
unpaid thereon, including additional dividends, to the date of final
distribution after distributions are made on the Series A Preferred Stock and
before any distribution is made on any Series C Preferred Stock. After payment
in full in accordance with the preceding sentence, the holders of the Series B
Preferred Stock shall not be entitled to any further participation in any
distribution in the event of liquidation, dissolution or winding up of the
affairs of the Surviving Corporation with respect to the shares of Series B
Preferred Stock.
    
 
    NO MANDATORY REDEMPTION.  The Surviving Corporation is not required to
redeem any shares of Series B Preferred Stock.
 
    VOTING RIGHTS.  The holders of Series B Preferred Stock will not be entitled
or permitted to vote on any matter required or permitted to be voted upon by the
stockholders of the Surviving Corporation, except as otherwise required by
Delaware law.
 
    NO RIGHT OF CONVERSION OR EXCHANGE.  The holders of Series B Preferred Stock
will not have any rights hereunder to convert such shares into or exchange such
shares for shares of any other class or classes or of any other series of any
class or classes of capital stock of the Surviving Corporation.
 
    NO PREEMPTIVE RIGHTS.  No holder of Series B Preferred Stock will possess
any preemptive rights to subscribe or acquire any unissued shares of capital
stock of the Surviving Corporation (whether now or hereafter authorized) or
securities of the Surviving Corporation convertible into or carrying a right to
subscribe to or acquire shares of capital stock of the Surviving Corporation,
provided that the holders of the Series B Preferred Stock shall have the rights
provided for in the Equity Holders Agreement described herein in "THE ROLLOVER
AGREEMENT."
 
SERIES C PREFERRED STOCK
 
   
    GENERAL.  In connection with the Transactions, the Investors and the
Management Stockholders will receive shares of Series C Preferred Stock.
Pursuant to the Certificate of Designation to be filed with the Secretary of
State of Delaware with respect to the Series C Preferred Stock included in Annex
D hereto, 5,000,000 shares of Series C Preferred Stock with a stated value of
$10.00 per share and a liquidation preference of $10.00 per share plus accrued
and unpaid dividends will be authorized for issuance. The Series C Preferred
Stock to be issued will be, when issued, fully paid and non-assessable.
    
 
                                      105
<PAGE>
    Neither the stated value nor the liquidation preference of the Series C
Preferred Stock is necessarily indicative of the actual value of the shares of
Series C Preferred Stock at or after the time of their issuance. The value of
the Series C Preferred Stock can be expected to fluctuate with changes in market
and economic conditions, the financial condition and prospects of the Surviving
Corporation and other factors that generally influence the value of securities.
 
   
    RANK.  The Series C Preferred Stock will, with respect to dividend rights
and rights on liquidation, winding up and dissolution of the Surviving
Corporation, rank junior to the Series A Preferred Stock and the Series B
Preferred Stock as to dividend distributions or distributions upon the
liquidation, winding up and dissolution of the Surviving Corporation. The Series
C Preferred Stock will also be junior in right of payment to all existing and
future indebtedness and obligations of the Surviving Corporation. As described
in "SOURCES AND AMOUNT OF FUNDS," the lending facilities to which the Surviving
Corporation will be a party will restrict payment of cash dividends by the
Surviving Corporation.
    
 
    DIVIDENDS.  Each holder of Series C Preferred Stock will be entitled to
receive, when, as and if declared by the Board of Directors, out of funds
legally available therefor, cash dividends on each share of Series C Preferred
Stock at a rate equal to $1.35 per share per annum. All dividends will be
cumulative and compounding, whether or not earned or declared, and will accrue
on a daily basis from the date of issuance of Series C Preferred Stock, and will
be payable semi-annually in arrears.
 
   
    LIQUIDATION PREFERENCE.  Upon any voluntary or involuntary liquidation,
dissolution or winding up of the Surviving Corporation, the holders of all
shares of Series C Preferred Stock then outstanding will be entitled to be paid
out of the assets of the Surviving Corporation available for distribution to its
stockholders an amount in cash equal to $10.00 per share, plus an amount equal
to full cumulative dividends (whether or not earned or declared) accrued and
unpaid thereon, including additional dividends, to the date of final
distribution, after distributions are made on the Series A Preferred Stock and
the Series B Preferred Stock (the "Series C Liquidation Preference"). After
payment in full in accordance with the preceding sentence, the holders of the
Series C Preferred Stock shall not be entitled to any further participation in
any distribution in the event of liquidation, dissolution or winding up of the
affairs of the Surviving Corporation with respect to the shares of Series C
Preferred Stock.
    
 
    NO RIGHT OF CONVERSION OR EXCHANGE.  The holders of Series C Preferred Stock
will not have any rights hereunder to convert such shares into or exchange such
shares for shares of any other class or classes or of any other series of any
class or classes of capital stock of the Surviving Corporation.
 
    NO PREEMPTIVE RIGHTS.  No holder of Series C Preferred Stock will possess
any preemptive rights to subscribe or acquire any unissued shares of capital
stock of the Surviving Corporation (whether now or hereafter authorized) or
securities of the Surviving Corporation convertible into or carrying a right to
subscribe to or acquire shares of capital stock of the Surviving Corporation.
 
   
    OPTIONAL REDEMPTION.  The Surviving Corporation may, at its option, redeem
at any time or from time to time, from any source of funds legally available
therefor, in whole or in part any or all of the shares of Series C Preferred
Stock, at $10.00 in cash per share, plus an amount equal to full cumulative
dividends (whether or not earned or declared) accrued and unpaid thereon to the
Series C redemption date. No partial redemption of Series C Preferred Stock may
be authorized or made unless prior thereto, full accrued and unpaid dividends
thereon for all dividend periods terminating on or prior to the Series C
redemption date and an amount equal to a prorated dividend thereon for the
period from the dividend payment date immediately prior to the redemption date
have been or immediately prior to the redemption notice are declared and paid in
cash or are declared and there has been a sum set apart sufficient for such cash
payment on the redemption date.

    In the event of a redemption of only a portion of the then outstanding
shares of Series C Preferred Stock, the Surviving Corporation will effect such
redemption pro rata according to the number of shares held by each holder of
Series C Preferred Stock.
 
    MANDATORY REDEMPTION.  All outstanding shares of the Series C Preferred
Stock will be redeemed from funds legally available therefor on December 31,
2012 at a price per share equal to the Series C Liquidation Preference on
December 31, 2012.

extent permissible) of the conditions set forth in the Merger Agreement (see
"THE MERGER--Conditions to the Consummation of the Merger"), MQ will merge with
and into the Company with the Company as the Surviving Corporation. The Merger
will be effected pursuant to the provisions of, and with the effect provided in,
the DGCL. The Merger will be consummated by filing the Certificate of Merger

will continue its corporate existence under the laws of the State of Delaware
and the Merger will have the effects set forth in the applicable sections of the
DGCL.
 
CERTIFICATE OF INCORPORATION AND BYLAWS
 
   
    At the Effective Time, the Certificate of Incorporation of MQ (which MQ will
amend prior to the Effective Time in order to provide for the Series A Preferred
Stock, the Series B Preferred Stock and the Series C Preferred Stock, and to
otherwise effect the transactions contemplated by the Merger Agreement as
provided in Annex D hereto), as in effect immediately prior to the Effective
Time, will be the Certificate of Incorporation of the Surviving Corporation
until thereafter amended (subject to the restrictions set forth in the Merger
Agreement) in accordance with applicable law. MQ will not amend its Certificate
of Incorporation or bylaws prior to the Effective Time, pursuant to the previous
sentence or otherwise, without the consent of the Company, not to be
unreasonably withheld.
    
 
   
    At the Effective Time, the Bylaws of MQ as in effect immediately prior to
the Effective Time, will be the Bylaws of the Surviving Corporation until
thereafter amended (subject to the restrictions set forth in the Merger
Agreement) in accordance with applicable law.
    
 
DIRECTORS
 
    The directors of MQ immediately prior to the Effective Time will be the
initial directors of the Surviving Corporation in each case until their
successors are elected or appointed and qualified. The officers of the Company
immediately prior to the Effective Time will be the initial officers of the
Surviving Corporation in each case until their successors are elected or
appointed and qualified. See "MANAGEMENT OF THE SURVIVING CORPORATION AND
RELATED TRANSACTIONS."
 
MERGER CONSIDERATION
 
   
    Upon the terms and subject to the conditions of the Merger Agreement, at the
Effective Time, automatically by virtue of the Merger and without any further
action on the part of any party hereto or the holders of any of the following
securities: (i) each MEDIQ Share issued and outstanding immediately prior to the
Effective Time, other than MEDIQ Shares held immediately prior to the effective
time by the Company or MQ or any direct or indirect subsidiary of the Company or
MQ, the Rolled Shares and Dissenting Shares will be converted into and become
the right to receive the Merger Consideration of, (A) $13.75 in cash without any
interest thereon and (B) 0.075 of a share of Series A Preferred Stock; (ii) each
MEDIQ Share that is issued and outstanding immediately prior to the Effective
Time and owned by MQ or the Company or any direct or indirect subsidiary of MQ
or the Company, will be canceled and no payment of any consideration will be
made with respect thereto; (iii) as a result of their conversion
    
 
                                      108
<PAGE>
   
pursuant to clause (i), all MEDIQ Shares (excluding any MEDIQ Shares described
in clause (ii), and any Dissenting Shares) issued and outstanding immediately
prior to the Effective Time will cease to be outstanding and will automatically
be canceled and retired, and each Certificate previously evidencing such MEDIQ
Shares will thereafter solely represent the right to receive the Merger
Consideration pursuant to clause (i). The holders of Certificates will cease to
have any rights with respect to such Converted Shares except as otherwise
provided in the Merger Agreement or by law; and each share of capital stock of
MQ issued and outstanding immediately prior to the Effective Time (including any
shares of capital stock issued by MQ in exchange for the Rolled Shares) will be
converted into and thereafter represent the same number of shares of the same
class of capital stock of the Surviving Corporation, provided that, each of the
Rolled Shares not owned by MQ immediately prior to the Effective Time will be
converted into and thereafter represent the number of shares of capital stock of
the Surviving Corporation as set forth in the Rollover Agreement.
    
 
DISSENTING SHARES
 
    Notwithstanding any provision of the Merger Agreement to the contrary, any
MEDIQ Shares held by a holder (a "Dissenting Stockholder") who has timely
demanded and perfected his demand for appraisal of his MEDIQ Shares (such shares
being "Dissenting Shares") in accordance with Section 262 of the DGCL and as of
the Effective Time has neither effectively withdrawn nor lost his right to such
appraisal will not represent a right to receive Merger Consideration for such
MEDIQ Shares, but rather the holder thereof will be entitled to only such rights
as are granted by the DGCL. SEE "DISSENTING STOCKHOLDERS' RIGHTS."
 
OPTION CONSIDERATION
 
   
    Upon the consummation of the Merger, each Option outstanding immediately
prior to the Effective Time under the Company's stock option plans or similar
arrangements, whether vested or unvested, will automatically become immediately
exercisable and each holder of an Option will have the right to receive from MQ
in respect of each MEDIQ Share underlying the Option (less applicable
withholding taxes) the Options Consideration which is equal to (i) a cash
payment in an aggregate amount equal to the difference between the cash portion
of the Merger Consideration of $13.75, less the exercise price per Share
applicable to such Option as stated in the applicable stock option agreement or
other agreement plus (ii) 0.075 of a share of Series A Preferred Stock; provided
that, with respect to any person subject to Section 16 of the Exchange Act, no
Option Consideration will be paid to such person until payment can be made
without liability to such person under Section 16(b) of the Exchange Act. The
Company will take such other actions (including, without limitation, giving
requisite notices to holders of Options advising them of such accelerated
exercisability and right to obtain payment for their respective Options) as are
necessary to fully advise holders of Options of their rights and to facilitate
their timely exercise of such rights. From and after the Effective Time, other
than as expressly set forth in the Merger Agreement, no holder of an Option will
have any other rights in respect thereof other than to receive payment for his
or her Options as set forth herein, and the Company will take all reasonably
necessary actions to terminate the Company's stock option plans and similar
arrangements. The provisions of this paragraph are subject to the Company
obtaining any required consents from the holders of any Options and the making
of any necessary amendments to the Company's stock option plans and other
similar agreements.
    
 
EXCHANGE OF MEDIQ SHARES
 
    At the Effective Time, MQ will remit (or cause to be remitted) to the
Exchange Agent, for the benefit of the holders of the MEDIQ Shares and Options,
an amount equal to the aggregate cash portion of the Merger Consideration and
the Option Consideration and a number of shares of Series A Preferred Stock
equal to the aggregate portion of the Merger Consideration and Option
Consideration necessary to pay the holders of the MEDIQ Shares and Options.
 
                                      109
<PAGE>
   
    As soon as practicable after the Effective Time and in no event later than
ten business days thereafter, the Surviving Corporation will cause the
distribution to holders of record of the Certificates and Option Agreements (as
of the Effective Time) of (i) notice of the effectiveness of the Merger and (ii)
a form of letter of transmittal and other appropriate materials and instructions
for use in effecting the surrender of the Certificates for payment of the Merger
Consideration therefor and in effecting the surrender of the Option Agreements
for payment of the Option Consideration therefor. In the event any Certificate
or Option Agreement has been lost or destroyed, the Exchange Agent is authorized
to accept an affidavit from the record holder of such Certificate or the party
to such Option Agreement in a form reasonably satisfactory to MQ, subject to
such other conditions as MQ may reasonably impose (including the posting of an
indemnity bond or other surety). Upon the surrender of each such Certificate,
together with such letter of transmittal, duly completed and validly executed in
accordance with the instructions thereto, the Exchange Agent will pay out of the
Payment Fund the Merger Consideration to the holders of such Certificates, less
any amounts required to be withheld pursuant to applicable tax laws. Upon the
surrender of Option Agreements formerly representing Options, together with a
letter of transmittal, duly completed and validly executed in accordance with
the instructions thereto, the Exchange Agent will pay the Option Consideration
to the holders of such Option Agreements, less any amounts required to be
withheld pursuant to applicable tax laws. The Exchange Agent will accept such
Certificates and Option Agreements upon compliance with such reasonable terms
and conditions as the Exchange Agent may impose to effect an orderly exchange
thereof in accordance with normal exchange practices. Until surrendered as
contemplated in this paragraph, (i) each Certificate will be deemed at any time
after the Effective Time to represent only the right to receive upon such
surrender the Merger Consideration, and (ii) each Option Agreement will be
deemed at any time after the Effective Time to represent only the right to
receive upon such surrender the Option Consideration. No interest will be paid
or will accrue on any cash payable as Merger Consideration or in lieu of any
fractional shares of Series A Preferred Stock, as the case may be.
    
 
   
    If any portion of the Cash Merger Consideration or Option Consideration is
to be paid or any certificate representing shares of Series A Preferred Stock is
to be issued to a person other than the person in whose name a canceled
Certificate or Option Agreement is registered, it is a condition to such payment
or issuance that such canceled Certificate or Option Agreement be surrendered
and properly endorsed or shall be otherwise in proper form for transfer, and
that the person requesting such payment shall have paid any transfer and other
taxes required by reason of such payment in a name other than that of the
registered holder of the certificate or instrument surrendered or shall have
established to the reasonable satisfaction of MQ and the Exchange Agent that
such tax either has been paid or is not payable.
    
 
    After the Effective Time of the Merger, there will be no further transfer on
the records of the Company or its transfer agent of Certificates representing
MEDIQ Shares which have been converted, in whole or in part, pursuant to the
Merger Agreement into the right to receive the Merger Consideration, and if such
Certificates are presented to the Company for transfer, they will be canceled
against delivery of cash and Certificates for shares of Series A Preferred Stock
as provided herein.
 
    To the extent not immediately required for payment with respect to
surrendered MEDIQ Shares and Options, proceeds in the Payment Fund will be
invested by the Exchange Agent as directed by the Surviving Corporation (as long
as such directions do not impair the rights of holders of MEDIQ Shares or
Options), in direct obligations of the United States of America, obligations for
which the faith and credit of the United States of America is pledged to provide
for the payment of principal and interest, commercial paper rated of the highest
investment quality by Moody's Investors Service, Inc. or Standard & Poor's
Ratings Services, or certificates of deposit issued by a commercial bank having
at least $5 billion in assets, and any net earnings with respect thereto will be
paid to the Surviving Corporation as and when requested by the Surviving
Corporation.
 
    No dividends or other distributions with a record date after the Effective
Time will be paid to the holder of any unsurrendered Certificate with respect to
the shares of Series A Preferred Stock represented thereby and no cash payment
in lieu of fractional shares will be paid to any such holder until the surrender
 
                                      110
<PAGE>
of such Certificate in accordance with the Merger Agreement. Subject to the
effect of applicable laws, following surrender of any such Certificate, there
shall be paid to the holder of the Certificate representing whole shares of
Series A Preferred Stock issued in connection therewith, without interest, (i)
at the time of such surrender or as promptly thereafter as practicable, the
amount of any cash payable in lieu of a fractional share of Series A Preferred
Stock to which such holder is entitled and the proportionate amount of dividends
or other distributions with a record date after the Effective Time of the Merger
theretofore paid with respect to such whole number of shares of Series A
Preferred Stock, and (ii) at the appropriate payment date, the proportionate
amount of dividends or other distributions with a record date after the
Effective Time but prior to such surrender and a payment date subsequent to such
surrender payable with respect to such whole number of shares of Series A
Preferred Stock.
 
    After the Effective Time, holders of Certificates will cease to have any
rights as stockholders of the Company, except as provided herein or under the
DGCL. All cash paid and shares of Series A Preferred Stock issued upon the
surrender for exchange of Certificates in accordance with the terms of the
Merger Agreement (including any cash paid) will be deemed to have been issued
(and paid) in full satisfaction of all rights pertaining to the MEDIQ Shares
exchanged theretofore represented by such Certificates. No interest will be paid
on any Merger Consideration or Option Consideration payable to former holders of
MEDIQ Shares or Options.
 
    Promptly following the one-year anniversary date of the Effective Date, the
Exchange Agent will return to the Surviving Corporation all cash and shares of
Series A Preferred Stock in its possession out of the Payment Fund relating to
the transactions described in the Merger Agreement, and the Exchange Agent's
duties will terminate. Thereafter, each holder of a Certificate or an Option
Agreement will look only to the Surviving Corporation and only as general
creditors thereof for payment of their claims for the Merger Consideration and
the Option Consideration, including any cash in lieu of fractional shares of
Series A Preferred Stock and any dividends or distributions with respect to such
shares to which such holders may be entitled, and each such holder of a
Certificate or an Option Agreement may surrender the same to the Surviving
Corporation and upon such surrender (subject to applicable abandoned property,
escheat or similar laws) the Surviving Corporation will deliver to such holder
the Merger Consideration and/or Option Consideration with respect to such shares
or Options, as applicable.
 
   
    No certificates or scrip representing fractional shares of Series A
Preferred Stock will be issued in connection with the Merger, and such
fractional share interests will not entitle the owner thereof to vote or to any
rights of a stockholder of the Surviving Corporation after the Merger. Each
holder of MEDIQ Shares exchanged pursuant to the Merger who would otherwise have
been entitled to receive a fractional share of Series A Preferred Stock (after
taking into account all MEDIQ Shares delivered by such holder) will receive, in
lieu thereof, a cash payment (without interest) therefor in an amount equal to
the value (determined with reference to the liquidation value of such Series A
Preferred Stock) of such fractional share, provided that such cash payments do
not exceed $50,000 in the aggregate. If such cash payments exceed $50,000, each
holder of MEDIQ Shares exchanged pursuant to the Merger who would otherwise have
been entitled to receive a fractional share of Series A Preferred Stock (after
taking into account all MEDIQ Shares delivered by such holder) will receive, in
lieu thereof, a cash payment (without interest) representing such holder's
proportionate interest in the net proceeds from the sale by the Exchange Agent
(following the deduction of applicable transaction costs), on behalf of all such
holders, of the Excess MEDIQ Shares representing such fractions. Such sale will
be made as soon as practicable after the Effective Time.
    
 
    None of MQ, the Company, their respective affiliates, or the Exchange Agent
will be liable to any person in respect of any shares of Series A Preferred
Stock (or dividends or distributions with respect thereto) or cash from the
Payment Fund delivered to a public official pursuant to any applicable abandoned
property, escheat or similar law. If any Certificates or Option Agreements have
not been surrendered prior to three years after the Effective Time (or
immediately prior to such earlier date on which any cash, if any, in lieu of
fractional shares of Series A Preferred Stock would otherwise escheat to
 
                                      111
<PAGE>
   
or become the property of any Governmental Entity (as defined herein)), any such
cash, dividends or distributions in respect of such Certificates and Option
Agreements will, to the extent permitted by applicable law, become the property
of the Company, free and clear of all claims or interest of any person
previously entitled thereto.
    
 
ADJUSTMENT OF MERGER CONSIDERATION AND OPTION CONSIDERATION
 
    The Merger Consideration and the Option Consideration have been calculated
based upon the representations and warranties made by the Company with regard to
its capitalization. In the event that, at the Effective Time, the actual number
of MEDIQ Shares outstanding and/or the actual number of MEDIQ Shares issuable
upon the exercise of outstanding options, warrants or similar agreements or upon
conversion of securities (including without limitation, as a result of any stock
split, stock dividend, including any dividend or distribution of securities
convertible into MEDIQ Shares, or a recapitalization) is more than described,
the Merger Consideration and the Option Consideration will be appropriately
adjusted downward; provided that, no adjustment will be made unless, at the
Effective Time, the actual number of MEDIQ Shares outstanding plus the actual
number of MEDIQ Shares issuable upon the exercise of all such options, warrants
or similar agreements or upon the conversion of securities is more than 20,000
more than described.

employees,
 
                                      112
<PAGE>
   
affiliates, representatives and other agents (including attorneys, investment
bankers and accountants) of the Company and its subsidiaries not to, directly or
indirectly, solicit, initiate or encourage any inquiry, proposal, indication of
interest or offer from any person that constitutes or would reasonably be
expected to lead to any Acquisition Proposal (as defined herein) or enter into
discussions or negotiate with any person or entity in furtherance of any such
inquiries, proposals, indications of interest or offers or to obtain or approve
any Acquisition Proposal, or agree to or endorse any Acquisition Proposal, and
the Company will immediately notify MQ of all relevant terms of any such
inquiries, proposals, indications of interest or offers received by the Company
or any of its subsidiaries or by any such officer, director, employee,
affiliate, representative or agent, relating to any of such matters, any
material change in the details (including any amendments or proposed amendments)
of any such inquiries, proposals, indications of interest or offers, the
identity of each of the persons or entities making such inquiries, proposals,
indications of interest or offers, and, if any such inquiry, proposal,
indication of interest or offer is in writing, the Company will immediately
deliver a copy thereof to MQ; provided, however, that if, prior to the Effective
Time, the Company receives an Acquisition Proposal (that was not solicited after
January 9, 1998), from a New Bidder (as defined herein) that the Board of
Directors of the Company, after receiving the written advice of its legal
counsel, reasonably believes that it has a fiduciary duty to consider, then the
Company, without violating the Merger Agreement, may thereafter furnish
information to and enter into discussions or negotiations with such New Bidder
making such Acquisition Proposal; provided that, before furnishing any
information to, or entering into discussions or negotiations with, any such New
Bidder, the Company shall have obtained an executed confidentiality agreement
containing confidentiality, "standstill" and other customary terms and
conditions no less favorable to the Company than the terms and conditions of the
Confidentiality Agreement by and between MQ and the Company, dated October 30,
1997. Neither the Board of Directors of the Company, nor any committee thereof,
may (a) withdraw or modify, in a manner adverse to MQ, the approval or
recommendation by the Board of Directors or any such committee thereof of the
Merger Agreement or the Merger, (b) approve or recommend any Acquisition
Proposal, (c) enter into any agreement with respect to any Acquisition Proposal,
(d) take any action to facilitate any other Acquisition Proposal in any respect,
or (e) terminate the Merger Agreement in connection with any Acquisition
Proposal; provided that, nothing contained in the Merger Agreement will prevent
the Board of Directors or any committee thereof, after receiving an Acquisition
Proposal as described in the immediately preceding sentence that, after
receiving the written advice of its legal counsel, the Board of Directors
reasonably believes that it has a fiduciary duty to consider, from considering,
negotiating, approving or recommending to the stockholders of the Company such
an Acquisition Proposal from a New Bidder, provided that the Board of Directors
of the Company reasonably determines (after consultation with its financial
advisors) that such Acquisition Proposal (a) would result in a transaction more
favorable to the Company's stockholders than the transaction contemplated by the
Merger Agreement, (b) is made by a person financially capable of consummating
such Acquisition Proposal, and (c) provides for the acquisition by such person
of all or substantially all of the assets of the Company and its Subsidiaries,
taken as a whole, or at least a majority of the MEDIQ Shares outstanding on a
fully diluted basis (any such Acquisition Proposal being referred to herein as a
"Superior Proposal"); provided further that, at least three business days prior
to the Board of Directors (or any committee thereof) withdrawing, modifying or
changing its recommendation regarding the approval of the Merger or the Merger
Agreement in a manner adverse to MQ, or recommending to the stockholders of the
Company any Acquisition Proposal, the Company will send notice thereof to MQ (a
"Superior Proposal Notice") and, concurrently therewith, will pay the Break-Up
Fee (in the amount set forth below) and the Documented Expenses to MQ. The
Superior Proposal Notice will be deemed an irrevocable notice of termination of
the Merger Agreement by the Company and the Merger Agreement will be terminated
in accordance therewith, unless MQ, within three business days after delivery to
MQ of the Superior Proposal Notice, (a) makes an offer that the Company's Board
of Directors reasonably determines (after consultation with its financial
advisors is at least favorable to the Company's Stockholders as the Superior
Proposal that is the subject of the Superior Proposal Notice, and (b) returns
the Break-up Fee and the Documented Expenses to the Company. For purposes
hereof, "Acquisition Proposal" means any proposal for a merger, consolidation,
tender or exchange offer or other
    
 
                                      113
<PAGE>
   
business combination involving the Company or the acquisition of any substantial
equity interest in, or a substantial portion of the assets of the Company and
its Subsidiaries considered as a whole, other than the transactions contemplated
by the Merger Agreement. For purposes hereof, "New Bidder" means any person or
entity other than those persons and entities to whom presentations by management
of the Company concerning a possible sale of the Company were made between
November 1, 1997 and the date of the Merger Agreement. Without limiting the
foregoing, it is agreed that any violation of the restrictions set forth in this
paragraph by any officer, director, employee, affiliate, representative or agent
(including attorneys, investment bankers and accountants) of the Company or any
of its Subsidiaries will be deemed to be a breach of this paragraph by the
Company; and concurrently with sending a Superior Proposal Notice, or upon any
termination by MQ of the Merger Agreement pursuant to Sections 8.1(e) or (f)
thereof, the Company will reimburse MQ for its Documented Expenses up to $5.0
million and pay to MQ the Break-Up Fee of $16.5 million, in each case by wire
transfer of immediately available funds to an account designated by MQ for such
purpose.
    
 
CERTAIN COVENANTS
 
   
    On February 10, 1998, the Company and BRS each filed a notification report
together with requests for early termination of the waiting period under the HSR
Act with the FTC and the Antitrust Division in respect of the Merger and the
related transactions. On February 24, 1998, the FTC and the Antitrust Division
granted early termination of the waiting period under the HSR Act with respect
to the Merger, effective immediately. At any time before or after consummation
of the Merger, notwithstanding that early termination of the waiting period
under the HSR Act has been granted, the Antitrust Division or the FTC could take
such action under the antitrust laws as it deems necessary or desirable in the
public interest, including seeking to enjoin the consummation of the Merger or
seeking divestiture of substantial assets of the Company. At any time before or
after the Effective Time of the Merger, and notwithstanding that early
termination of the waiting period under the HSR Act has been granted, any state
could take such action under the antitrust laws as it deems necessary or
desirable in the public interest. Such action could include seeking to enjoin
the consummation of the Merger or seeking divestiture of substantial assets of
the Company. The Company and MQ will use their best efforts to respond as
promptly as practicable to any inquiries received from the FTC or the Antitrust
Division for additional information or documentation and to respond as promptly
as practicable to all inquiries and requests received from any state attorney
general or any other governmental entity, in connection with antitrust matters.
The Company and MQ have agreed to use commercially reasonable efforts to
overcome any objections which may be raised by the FTC or the Antitrust
Division. MQ has agreed to reimburse the Company for all expenses (including
attorney's fees) reasonably incurred by the Company in connection with matters
referred to in the immediately preceding sentence. The Company will make,
subject to the condition that the transactions contemplated by the Merger
Agreement actually occur, any undertakings (including undertakings to make
divestitures, provided, in any case, that such undertakings to make divestitures
need not themselves be effective or made until after the transactions
contemplated hereby actually occur) required in order to comply with the
antitrust requirements or laws of any governmental entity, including the HSR
Act, in connection with the transactions contemplated by the Merger Agreement,
provided that no such divestiture or undertaking will be made unless reasonably
acceptable to MQ.
    
 
    The Company has agreed to prepare and file with the Commission the
Registration Statement of which this Proxy Statement/Prospectus is a part. MQ
and the Company have also agreed to prepare and file with the Commission the
Schedule 13E-3 with respect to the transactions contemplated by the Merger
Agreement. All filing fees required to be paid, and all printing, mailing and
other costs of dissemination with respect to the Registration Statement, this
Proxy Statement/Prospectus or Schedule 13E-3 will be paid by the Company. The
Company has agreed to use its commercially reasonable efforts to take all steps
necessary to cause the Schedule 13E-3 to be filed with the Commission and to be
disseminated to the holders of MEDIQ Shares, in each case, as and to the extent
required by applicable federal securities laws. The Company has agreed to take
any action required to be taken under any applicable state securities laws
 
                                      114
<PAGE>
in connection with the registration and qualification of the shares of the
capital stock of the Company to be issued in connection with the Merger.
 
   
    To the extent requested by MQ, each of the parties has agreed to cooperate
with each other in taking, or causing to be taken, all actions necessary to
delist the MEDIQ Shares from the AMEX; provided that such delisting will not be
effective until after the Effective Time. The parties also acknowledged that it
is MQ's intention that, following the Merger, none of the shares of the
Surviving Corporation capital stock will be listed on the AMEX or any other
national securities exchange and will not be quoted on the NASDAQ.
Notwithstanding that the Surviving Corporation may not be required to remain
subject to the reporting requirements of Section 13 or 15(d) of the Exchange
Act, the Surviving Corporation will file with the Commission,for the two (2)
years following the Effective Time, such reports as are specified in Section 13
and 15(d) of the Exchange Act and required to be filed in respect of securities
similar to the Series A Preferred Stock by issuers subject to the reporting
requirements of Section 13 of the Exchange Act, such reports to be so filed at
the times specified for the filings of such reports required under such
Sections; provided that the Surviving Corporation will have no obligation to
file such reports if fewer than 500,000 shares of Series A Preferred Stock
remain outstanding.
    
 
    The Company will give MQ the opportunity to participate in the defense or
settlement of any litigation against the Company and its directors directly
relating to any of the transactions contemplated by the Merger Agreement until
the Effective Time provided, however, that no such settlement will be agreed to
without MQ's consent, which consent will not be unreasonably delayed or
withheld; and provided further that no settlement requiring a payment by a
director will be agreed to without such director's consent.
 
   
    At the request of MQ, prior to the Effective Time, the Company will
contribute all of its assets and liabilities (including any shares of capital
stock of its subsidiaries other than MEDIQ/PRN) to MEDIQ/ PRN, on terms and
conditions reasonably acceptable to MQ.
    
 
    The Company has agreed to cooperate with any reasonable requests of MQ or
the Commission related to the recording of the Merger as a recapitalization for
financial reporting purposes and to take such actions consistent with the terms
of the Merger Agreement, at MQ's reasonable request, as may be required to cause
the Merger to be recorded as such, including, without limitation, to assist MQ
and its affiliates with any presentation to the Commission with regard to such
recording and to include appropriate disclosure with respect to such recording
in all filings with the Commission and all mailings to stockholders made in
connection with the Merger. In furtherance of the foregoing, the Company will
provide to MQ for the prior review of MQ's advisors any description of the
transactions contemplated by the Merger Agreement which is meant to be
disseminated.
 
    The Company has agreed to provide, and will cause its Subsidiaries and its
and their respective officers and employees to provide, all reasonable
cooperation in connection with the arrangement of any financing contemplated by
the Merger Agreement, including without limitation, (a) the execution and
delivery of any commitment letters, underwriting or placement agreements, loan,
pledge and security documents, other definitive financing documents, or other
requested certificates or documents reasonably requested, (b) making available
on a timely basis any financial information of the Company and its Subsidiaries
that may be reasonably requested by MQ, (c) obtaining the solvency opinion
referred to in the Merger Agreement and obtaining the comfort letters and update
thereof from the Company's independent certified public accountants, with such
letters to be in customary form and to cover matters of the type customarily
covered by accountants in such financing transactions, and (d) making reasonably
available representatives and employees of the Company and its accountants and
attorneys in connection with any such financing, including for purposes of due
diligence and marketing efforts (including participation in "road shows")
related thereto. The obligations (including the payment of any fees and
expenses) on behalf of the Company in connection with any expenses of road
shows, commitment letters or other financings or
 
                                      115
<PAGE>
refinancings contemplated hereby will be subject to the occurrence of the
closing under the Merger Agreement.
 
    The Company has agreed that it will continue to timely make any such filings
with the Commission as may be required by applicable federal securities laws,
including without limitation required Quarterly Reports on Form 10-Q and Current
Reports on Form 8-K.
 
EMPLOYEE BENEFITS
 
   
    As of the Effective Time, the employees of the Company and each of its
subsidiaries (the "Company Employees") will continue employment with the
Surviving Corporation and its subsidiaries, respectively, in the same positions
and at the same level of wages and/or salary and employee benefits, as in effect
on the date of the Merger Agreement, with such changes as may occur before the
Effective Time in the ordinary course of business consistent with past practice.
Except as may be specifically required by applicable law or any agreement by
which the Company is bound, the Surviving Corporation and its subsidiaries will
have the same right to terminate or change the conditions of any Company
Employee's employment or to amend, modify or terminate any employee benefit plan
program or policy, as the Company and its subsidiaries presently.
    
 
    Notwithstanding any provisions of any Company or subsidiary employee benefit
plan, program or policy to the contrary, at the Effective Time any right of any
employee to make future investments in shares of the Company or to receive
employer contributions in shares of the Company will terminate, and any shares
of the Company held under any such plan, program or policy will be treated in
the Merger in accordance with the Merger Agreement, and any Merger Consideration
(including shares of Series A Preferred Stock) received thereunder will be, to
the extent applicable, reinvested in accordance with the terms of such plan,
program or policy. Before the Effective Time, the Company and its Subsidiaries
will take any and all action reasonably required to assure that the right of any
employee to make future investments in shares of the Company and the obligation
of the Company or any of its subsidiaries to contribute shares of the Company
under any such plan, program or policy is terminated as of the Effective Time.
 
INDEMNIFICATION
 
   
    Subsequent to the Effective Time, the Surviving Corporation will not, until
the later of (a) the six-year anniversary date of the Effective Date or (b) the
permitted termination or expiration date of any existing indemnification
agreement or arrangement of the Company or any of its subsidiaries disclosed on
the applicable schedule to the Merger Agreement (the period between the
Effective Date and the later of such subsequent dates, the "Indemnification
Period"), amend the Certificate of Incorporation or Bylaws of the Surviving
Corporation or take any other action, or fail to take any action, the effect of
which amendment, action or failure to act would be to reduce or limit the rights
to indemnity or advancement of expenses afforded to those persons who served as
directors or officers of the Company or any present or past subsidiary at any
time prior to the Effective Time or to hinder, delay or make more difficult in
any way the exercise of such rights to indemnity or advancement of expenses or
the ability of the Surviving Corporation or any subsidiary to indemnify such
persons or advance expenses. The Surviving Corporation will at all times
promptly exercise the powers granted to it by its Certificate of Incorporation,
its Bylaws and by applicable law to indemnify (and to advance expenses to),
subject to the terms and conditions thereof, to the fullest extent possible
those persons who served as directors or officers of the Company and present or
past subsidiaries prior to the Effective Time against all claims and expenses
made against or incurred by them arising from their service in such capacities.
Should any such person be made a party or be threatened to be made a party to
any threatened, pending or completed action, suit or proceeding at any time
during the Indemnification Period, by reason of the fact that he was a director
or officer of the Company or any present or past subsidiary or was serving as an
officer or director of any other enterprise at the request of the Company, the
indemnification provisions of the Merger Agreement will continue in
    
 
                                      116
<PAGE>
effect until the final disposition of all such actions, suits or proceedings,
whether or not the Indemnification Period has expired. These provisions are
intended to be for the benefit of, and are enforceable by, each person entitled
to indemnification thereunder, his heirs and his personal representatives. In
the event the Surviving Corporation or MQ or any of their respective successors
or assigns (a) consolidates with or merges into any other person and the
Surviving Corporation is not the continuing or surviving corporation or entity
of such consolidation or merger or (b) transfers all or substantially all of its
properties and assets to any person, the Surviving Corporation has agreed to
ensure that proper provision will be made so that the successors and assigns of
the Surviving Corporation will assume the indemnification obligations set forth
in the Merger Agreement. The Surviving Corporation will obtain and maintain in
effect for not less than six years after the Effective Date, the current
directors' and officers' liability insurance policies maintained by the Company
(provided that the Surviving Corporation may substitute therefor a policy or
policies providing substantially equivalent coverage containing similar terms
and conditions so long as no lapse in coverage occurs as a result of such
substitution) with respect to all matters, including the transactions
contemplated hereby, occurring prior to, and including the Effective Date;
provided that in no event will the Surviving Corporation be required to expend
more than 200% of the current annual premiums paid by the Company for such
coverage (the "Maximum Premium"); and provided, further, that if the Surviving
Corporation is unable to obtain the amount of insurance required by the Merger
Agreement for such aggregate premium, the Surviving Corporation will obtain, if
available, as much insurance as can be obtained for an annual premium not in
excess of the Maximum Premium.
 
FINANCING
 
   
    MQ will use commercially reasonable efforts, subject to normal conditions,
to arrange, as promptly as practicable, and consummate the financings described
in the commitment letters (or involving such other financing as may be
acceptable to MQ in its sole discretion) in respect of the transactions
contemplated by the Merger Agreement on customary commercial terms, including,
subject to normal conditions, using commercially reasonable efforts to assist
the Company in the negotiation of definitive agreements with respect thereto and
to satisfy all conditions applicable to MQ in such definitive agreements.
Subject to the Company having received the proceeds of such financings, MQ at
Closing will be capitalized with an equity contribution sufficient to finance
the transaction, in an amount up to $98.6 million. MQ will be under no
obligation pursuant to the immediately preceding sentence unless and until the
Company receives the proceeds of such financings on terms consistent with the
commitment letters or such other financings as may be acceptable to MQ in its
sole discretion. MQ will use commercially reasonable efforts to obtain a
solvency opinion in connection with such financings, addressed to the Board.
    
 
                                      117
<PAGE>
CONDITIONS
 
    All obligations of MQ under the Merger Agreement are subject to, among other
things, the fulfillment or waiver (to the extent permitted by the Merger
Agreement and applicable law), prior to or at the Effective Time, of the
following conditions:
 
        (a) The required Company stockholder approvals shall have been obtained.
 
        (b) The representations and warranties made by the Company shall be true

    had and would not reasonably be expected to result in a material adverse
    effect with respect to MQ.
 
        (c) MQ shall have performed and complied with all covenants required by

TERMINATION
 
    The Merger Agreement may be terminated and the Merger contemplated hereby
may be abandoned at any time, notwithstanding approval thereof by the applicable
stockholders, but prior to the Effective Time:
 
   
        (a) by mutual written consent of MQ and the Company;
    
 
        (b) by either MQ or the Company, if any of the conditions to such
    party's obligation to consummate the transactions contemplated in the Merger
    Agreement shall have become impossible to satisfy;
 
   
        (c) by either MQ or the Company, if the Merger has not been consummated
    on or before August 31, 1998 (unless the failure to consummate the Merger by
    such date shall be due to the action or failure to act of the party seeking
    to terminate the Merger Agreement in breach of such party's obligations
    under the Merger Agreement) provided that the right to terminate the Merger
    Agreement pursuant to this provision solely because of the failure of
    satisfaction of the conditions relating to litigation, shall not accrue
    until September 30, 1998;
    
 
   
        (d) by the Company, effective three business days after delivery to MQ
    of a Superior Proposal Notice, which Superior Proposal Notice shall have
    been preceded or accompanied by payment of the Break-Up Fee and the
    Documented Expenses to MQ, unless, within such three business-day period, MQ
    (A) makes an offer that the Company's Board of Directors reasonably
    determines (after
    
 
                                      120
<PAGE>
   
    consultation with its financial advisors) is at least as favorable to the
    Company's stockholders as the Superior Proposal that is the subject of the
    Superior Proposal Notice, and (B) returns the Break-Up Fee and the
    Documented Expenses to the Company;
    
 
   
        (e) by MQ if (A) the Board of Directors of the Company (or any committee
    thereof) (i) withdraws, modifies or changes its recommendation regarding the
    approval of the Merger or the Merger Agreement or the transactions
    contemplated hereby in a manner adverse to MQ, (ii) shall have recommended
    to the stockholders of the Company any Acquisition Proposal; (iii) shall
    have taken any action in violation of the covenant prohibiting solicitation
    of other transactions; (iv) shall have failed to reaffirm publicly its
    recommendation regarding the approval of the Merger or the Merger Agreement
    and the transactions contemplated hereby within three business days of
    receipt of MQ's written request to do so; or (v) shall have resolved, or
    entered into any agreement, to do any of the foregoing, or (B) the parties
    (other than MQ) to the Option Agreement or the Stockholder Agreement shall
    have breached their material obligations thereunder to MQ, or (C) or there
    shall have been a change in control of the Company;
    
 
   
        (f) by MQ if (i) the Company is in breach at any time prior to the
    Effective Time of any of the representations and warranties made by the
    Company as though made on and as of such date, unless the inaccuracies
    (without giving effect to any materiality or material adverse effect
    qualifications or materiality exceptions contained therein) in such
    representations and warranties, individually or in the aggregate, have not
    had and would not reasonably be expected to result in a material adverse
    effect with respect to the Company, or (ii) the Company shall not have
    performed and complied in all material respects with all covenants required
    by the Merger Agreement to be performed or complied with by the Company on
    and as of such date, which breach in the case of clauses (i) and (ii) cannot
    be or has not been cured, in all material respects, within 15 days after the
    giving of written notice to the Company; or
    
 
   
        (g) by the Company if (i) MQ is in breach at any time prior to the
    Effective Time of any of the representations and warranties made by MQ as
    though made on and as of such date, unless the inaccuracies (without giving
    effect to any materiality or material adverse effect qualifications or
    materiality exceptions contained therein) in such representations and
    warranties, individually or in the aggregate, have not had and would not
    reasonably be expected to result in a material adverse effect with respect
    to MQ, or (ii) MQ shall not have performed and complied in all material
    respects with all covenants required by the Merger Agreement to be performed
    or complied with by MQ on and as of such date, which breach in the case of
    clauses (i) and (ii) cannot be or has not been cured, in all material
    respects, within 15 days after the giving of written notice to MQ.
    
 
    Any party desiring to terminate the Merger Agreement is required to give
written notice of such termination and the reasons therefor to the other
parties.
 
    If the Merger Agreement is terminated pursuant to the above provisions, the
Merger Agreement will become void and of no effect and no party hereto shall
have any liability to the other for costs, expenses, loss of anticipated profits
or otherwise, except that (i) the agreements contained in certain sections of
the Merger Agreement concerning confidentiality and the payment of certain fees
and expenses, will survive the termination of the Merger Agreement, and (ii)
nothing will relieve any party from liability for any willful breach of the
Merger Agreement.
 
EXPENSES
 
   
    Except as expressly provided in the Merger Agreement, each party will bear
its respective expenses, fees and costs incurred or arising in connection with
the negotiation and preparation of the Merger Agreement and all transactions
related thereto, and the parties shall have no liability between or among
themselves for such expenses, fees or costs.

AMENDMENT AND WAIVER
 
   
    The Merger Agreement may be amended only by a written instrument duly signed
by the parties thereto or their respective successors or assigns. The Merger
Agreement may be amended by the parties thereto by action taken by or on behalf
of their respective Boards of Directors at any time prior to the Effective Time;
provided, however, that after approval of the Merger by the stockholders of the
Company, no amendment may be made which would reduce the amount or change the
type of consideration into which each share of MEDIQ Common Stock or MEDIQ
Preferred Stock or Option will be converted upon consummation of the Merger.

                             STOCK OPTION AGREEMENT
 
    The following is a brief summary of the material provisions of the Stock
Option Agreement, a copy of which is attached as Annex E to the Proxy
Statement/Prospectus and is incorporated herein. This summary is qualified in
its entirety by reference to the full text of the Stock Option Agreement.
Capitalized terms that are used in this section and are not otherwise defined
have the respective meanings given to them in the Stock Option Agreement.
 
GENERAL
 
   
    As a condition to entering into the Merger Agreement, MQ required that the
Rotko Entities enter into the Stock Option Agreement with MQ pursuant to which
the Rotko Entities granted MQ the option to purchase, under certain
circumstances, at an exercise price of $14.50 per share, up to 4,701,464 shares
of MEDIQ Common Stock owned or subsequently acquired by the Rotko Entities
(which represents approximately 24% of the total outstanding MEDIQ Common Stock
as of January 14, 1998) and 4,730,006 shares of MEDIQ Preferred Stock owned or
subsequently acquired by the Rotko Entities (which represents approximately 75%
of the outstanding MEDIQ Preferred Stock as of January 14, 1998)(collectively
the "Rotko Shares").
    
 
    The Stock Option Agreement may have the effect of discouraging persons who
might now or prior to the Effective Time be interested in acquiring all of or a
significant interest in, or otherwise effecting a business combination with, the
Company, from considering or proposing such a transaction.
 
    The Rotko Option becomes exercisable only upon certain events set forth in
the Stock Option Agreement (each, a "Purchase Event"). A Purchase Event means
any of the following events:
 
   
        (i) any person (other than MQ or any of its subsidiaries) shall have
    commenced (as such term is defined in Rule 14d-2 under the Exchange Act), or
    shall have filed a registration statement under the Securities Act, with
    respect to, a tender offer or exchange offer to purchase any MEDIQ Common
    Stock or MEDIQ Preferred Stock such that, upon consummation of such offer,
    such person would have beneficial ownership of 25% or more of the then
    outstanding MEDIQ Common Stock or MEDIQ Preferred Stock or more than 25% of
    the total voting power of the Company;
    
 
   
        (ii) the Company or any of its Subsidiaries shall or shall have entered
    into, authorized, recommended, proposed or publicly announced an intention
    to enter into, authorize, recommend, or propose, an agreement, arrangement
    or understanding with any person (other than MQ or any of its subsidiaries)
    to, or any person (other than MQ or any of its subsidiaries) shall have
    publicly announced a bona fide intention to (A) effect any Acquisition
    Proposal with the Company, (B) purchase, lease or otherwise acquire 25% or
    more of the assets of the Company and its consolidated subsidiaries or (C)
    purchase or otherwise acquire (including by way of merger, consolidation,
    tender or exchange offer or similar transaction) beneficial ownership of
    securities representing 25% or more of the voting power of the Company or
    any of its significant subsidiaries.
    
 
        (iii) any person (other than MQ or any subsidiary or stockholder of MQ,
    and other than a Rotko Entity) shall have acquired beneficial ownership or
    the right to acquire beneficial ownership of 25% or more of the MEDIQ Common
    Stock, MEDIQ Preferred Stock or voting power of the Company or there shall
    otherwise have been a change in control of the Company;
 
   
        (iv) the Company's Board of Directors (or any committee thereof) (a)
    shall have withdrawn, modified or changed its recommendation regarding the
    approval of the Merger or the Merger Agreement or the transactions
    contemplated thereby in a manner adverse to MQ, (b) shall have recommended
    to the stockholders of the Company any Acquisition Proposal, (c) shall have
    taken any action in violation of the covenant in the Merger Agreement
    prohibiting solicitation of other transactions, (d) shall have failed to
    reaffirm publicly its recommendation regarding the approval of the Merger or
    the Merger Agreement and the transactions contemplated thereby within three
    
 
                                      123
<PAGE>
   
    business days of receipt of MQ's written request to do so, or (e) shall have
    resolved, or entered into any agreement, to do any of the foregoing;
    
 
        (v) if any of the Rotko Entities shall have breached in any material
    respect any of their respective obligations under the Stockholder
    Agreements;
 
   
        (vi) if at the Special Meeting (including any adjournment or
    postponement thereof) the Company stockholder approvals shall not have been
    obtained or if the Company shall not have called and held a Special Meeting
    prior to the termination of the Merger Agreement after being requested to do
    so by MQ as provided in the Merger Agreement;
    
 
   
        (vii) the Merger Agreement shall have been terminated (or MQ shall have
    the right to terminate the Merger Agreement) (x) pursuant to certain
    provisions of the Merger Agreement relating to failure to satisfy conditions
    to the Merger or if the Merger is not consummated by August 31, 1998 and the
    Company's failure to perform any material covenant or obligation under, or
    other breach by the Company of, the Merger Agreement has caused or resulted
    in the failure of the Merger to occur on or before the date of such
    termination (or right to termination), or (y) pursuant to certain provisions
    of the Merger Agreement relating to (a) a Superior Proposal Notice, (b) a
    change in the Board of Directors recommendation for the Merger, (c) a breach
    of the Stock Option Agreements or Stockholder Agreements, (d) a change in
    control, or (e) the Company's material breach of its representations and
    warranties or failure to perform or comply with its covenants in all
    material respects; or
    
 
        (viii) the Company shall have delivered a Superior Proposal Notice.
 
TERMINATION
 
   
    To the extent the Rotko Option shall not have been previously exercised, it
will terminate and be of no further force and effect upon the earlier to occur
of (i) the Effective Time of the Merger; (ii) in the case of a termination of
the Merger Agreement in accordance with certain provisions for termination
relating to (a) mutual consent, (b) failure to satisfy conditions of the Merger,
(c) failure to consummate the transaction prior to August 31, 1998 or (d) MQ's
material breach of a representation and warranty or failure to perform or comply
with its covenants in all material respects, the date of such termination;
provided that (x) no Purchase Event shall have occurred prior to such
termination and (y) the Company shall not have been in breach of the Merger
Agreement prior to such termination; and (iii) in the case of any other
termination of the Merger Agreement, the date that is six months following such
termination (such date, the "Option Termination Date").
    
 
   
    Notwithstanding the foregoing, if the Rotko Option cannot be exercised
before the Option Termination Date as a result of any injunction, order or
similar restraint issued by a court of competent jurisdiction, the Rotko Option
will expire on (and the Option Termination Date will be so extended until the
earlier of) (i) the 30th business day after such injunction, order or restraint
shall have been dissolved or (ii) when such injunction, order or restraint shall
have become permanent and no longer subject to appeal, as the case may be.
    
 
EXERCISE OF OPTION
 
    The MEDIQ Shares to be acquired pursuant to exercise of the Rotko Option (if
such option is exercised in part) will be allocated pro rata as between shares
of MEDIQ Common Stock and MEDIQ Preferred Stock and as among each Stockholder
based upon the number of MEDIQ Shares owned by them. If MQ exercises the Rotko
Option for no more than two million MEDIQ Shares in the aggregate, the Rotko
Entities may designate among themselves the stockholders who will sell MEDIQ
Shares to MQ pursuant to such partial exercise of the Rotko Option, provided
that (x) the aggregate number of shares of MEDIQ Common Stock and MEDIQ
Preferred Stock to be sold to MQ pursuant to such exercise will remain the same
as if there had been no designation and (y) such designation will not adversely
affect the accounting treatment or economic impact of exercise of the Rotko
Option to MQ.
 
                                      124
<PAGE>
    In the event MQ exercises the Rotko Option in part and acquires MEDIQ Shares
which represent a majority of the total voting power of the Company's capital
stock, on a fully-diluted basis, MQ agrees that it will exercise the Rotko
Option in respect of all the subject MEDIQ Shares.
 
    In the event of any change in the MEDIQ Shares by reason of a stock
dividend, split-up, recapitalization, merger, consolidation, reorganization,
combination, exchange of shares or similar transaction, the type and number of
shares or securities subject to the Rotko Option, the purchase price therefor
will be adjusted appropriately so that MQ will receive upon exercise of the
Rotko Option the same class and number of outstanding shares or other securities
or property that MQ would have received in respect of the MEDIQ Common Stock or
MEDIQ Preferred Stock if the Rotko Option had been exercised immediately prior
to such event, or the record date therefor, as applicable.
 
    If, in connection with the exercise of the Rotko Option, prior notification
to or approval of any governmental entity is required, then the required notice
or application for approval will be promptly filed and/or expeditiously
processed by each member of the Rotko Entities and periods of time that
otherwise would run pursuant hereto (if any) will run instead from the date on
which any such required notification period has expired or been terminated or
such approval has been obtained, and in either event, any requisite waiting
period shall have passed.
 
                           THE STOCKHOLDER AGREEMENTS
 
    The following is a brief summary of the material provisions of the
Stockholder Agreements, copies of which agreements are attached as Annex F to
this Proxy Statement/Prospectus and are incorporated herein by reference. This
summary is qualified in its entirety by reference to the full text of the
Stockholder Agreements. Capitalized terms that are used in this section and not
defined have the respective meaning given to them in the Stockholder Agreements.
 
GENERAL
 
   
    As a condition to entering into the Merger Agreement, each of the Rotko
Entities entered into a separate Stockholder Agreement, pursuant to which, among
other things, the Rotko Entities granted to MQ an irrevocable proxy and power of
attorney to vote all of their respective MEDIQ Shares (i) in favor of the
Merger, the execution and delivery by the Company of the Merger Agreement and
the approval of the terms thereof and each of the other actions contemplated by
the Merger Agreement, the Stockholder Agreements and the Stock Option Agreement
and any actions required in furtherance thereof; (ii) against any action or
agreement that would result in a breach in any material respect of any covenant,
representation or warranty or any other obligation of the Company under the
Merger Agreement or under the Stockholder Agreements or the Stock Option
Agreement; and (iii) except as otherwise agreed to in writing in advance by MQ,
against the following actions (other than the Merger and the transactions with
the Rotko Entities or their affiliates contemplated by the Merger Agreement):
(1) any extraordinary corporate transaction, such as a merger, consolidation or
other business combination involving the Company or its subsidiaries; (2) any
sale, lease or transfer of a material amount of assets of the Company or its
subsidiaries or a reorganization, recapitalization, dissolution or liquidation
of the Company or its subsidiaries; (3) (a) any change in the majority of the
Board of Directors of the Company; (b) any material change in the present
capitalization of the Company or any amendment of the Company's Certificate of
Incorporation or Bylaws; (c) any other material change in the Company's
corporate structure or business; or (d) any other action, which is intended, or
could reasonably be expected, to impede, interfere with, delay, postpone,
discourage or materially adversely affect the contemplated economic benefits to
MQ of the Merger or the transactions contemplated by the Merger Agreement, the
Stockholder Agreements or the Stock Option Agreement. The Rotko Entities will
not enter into any agreement or understanding with any person or entity to vote
or give instructions in any manner inconsistent with clauses (i), (ii) or (iii)
of the preceding sentence.
    
 
                                      125

    The Rotko Entities represented and warranted that they have sole voting
power and sole power to issue instructions with respect to the matters set forth
in the Stockholder Agreements, sole power of disposition, sole power of
conversion, sole power to demand appraisal rights and sole power to engage in
the actions set forth in the Stockholder Agreements, in each case with respect
to the MEDIQ Shares owned by such Rotko Entities.
 
   
    The Stockholder Agreements may have the effect of discouraging persons who
might now or prior to the Effective Time be interested in acquiring all of or a
significant interest in, or otherwise affecting a business combination with, the
Company from considering or proposing such a transaction.
    
 
AGREEMENT NOT TO TRANSFER
 
    Each of the Rotko Entities agreed that it will not, and that such Rotko
Entity will not permit any company, trust or other person or entity controlled
by it to, and will not permit any of its affiliates to, contract to sell, sell
or otherwise transfer or dispose of any MEDIQ Shares owned by it or any interest
therein or securities convertible therein to or any voting rights with respect
thereto, other than (i) pursuant to the Merger, (ii) pursuant to the Stock
Option Agreement and (iii) with MQ's prior written consent. Each of the Rotko
Entities agreed that it will not convert any MEDIQ Preferred Stock into MEDIQ
Common Stock or take any other action which diminishes the benefits of the
Stockholder Agreement to MQ.
 
CERTAIN COVENANTS OF THE ROTKO ENTITIES
 
   
    The Rotko Entities agreed to, and agreed to cause any company, trust or
other person or entity controlled by the Rotko Entities to, cooperate fully with
MQ in connection with the Merger Agreement, the Stock Option Agreement, the
Stockholder Agreements and the transactions contemplated thereby. The Rotko
Entities agreed that they will not, and will not permit any such company, trust
or other entity or person to, and will not authorize any of their affiliates to,
directly or indirectly (including through their officers, directors, employees
or other representatives) solicit, initiate, encourage or facilitate, or furnish
or disclose non-public information in furtherance of, any inquiries or the
making of any proposal with respect to any recapitalization, merger,
consolidation or other business combination involving the Company, or the
acquisition of any capital stock or any material portion of the assets (except
for acquisition of assets in the ordinary course of business consistent with
past practice and not material in the aggregate to the Company) of the Company,
or any combination of the foregoing (a "Competing Transaction"), or negotiate,
explore or otherwise engage in discussions with any person (other than MQ and
its affiliates, or their respective directors, officers, employees, agents and
representatives) with respect to any Competing Transaction or enter into any
agreement, arrangement or understanding with respect to any Competing
Transaction or agree to or otherwise assist in the effectuation of any Competing
Transaction; provided, however, that nothing in the Stockholder Agreements will
require the Rotko Entities to prevent or restrict any director or trustee of the
Rotko Entities who is a director or officer of the Company from taking any
action in his capacity as a director or officer of the Company to the extent
such director or officer would be permitted to take such action under the Merger
Agreement.
    
 
TERMINATION
 
    The Stockholder Agreements may be terminated at the option of any party at
any time after the Option Termination Date.
 
                             THE ROLLOVER AGREEMENT
 
    The following is a brief summary of the material provisions of the Rollover
Agreement, a copy of which is attached as Annex G to this Proxy
Statement/Prospectus and is incorporated herein by reference. This summary is
qualified in its entirety by reference to the full text of the Rollover
Agreement.
 
                                      126
<PAGE>
Capitalized terms that are used in this section and are not defined have the
respective meanings given to them in the Rollover Agreement.
 
    As a condition to entering into the Merger Agreement, MQ required that the
Rotko Entities enter into a Rollover Agreement pursuant to which the Rotko
Entities agreed to convert an aggregate of 1,000,000 Rolled Shares of MEDIQ
Preferred Stock into certain securities of the Surviving Corporation specified
in the Rollover Agreement, instead of receiving cash merger consideration of
$13.75 and .075 of a share of Series A Preferred Stock per Rolled Share. MQ
required that the Rotko Entities enter into the Rollover Agreement in order to
reduce the amount required to finance the Merger and the other transactions
contemplated by the Merger Agreement and to facilitate the recordation of the
Merger for accounting purposes as a recapitalization of the Company. Mr. Rotko,
who was represented by Mr. Bonovitz and the firm of Duane Morris & Heckscher
LLP, on behalf of the Rotko Entities, separately negotiated the Rollover
Agreement with MQ.
 
    The parties to the Rollover Agreement agreed that either (i) immediately
prior to the Effective Time, the Rotko Entities will transfer the contribution
of the Rolled Shares in exchange for securities of MQ, which at the Effective
Time will be converted into the Converted Shares (1,340,200 shares of Series B
Preferred Stock and a number of shares of Surviving Corporation Common Stock
equal to 10.98% (assuming an initial investment of $10.0 million of Common
Stock), of the total outstanding shares of Surviving Corporation Common Stock)
or (ii) the Certificate of Merger will provide that the Rolled Shares will be
converted into the Converted Shares. The decisions as to whether alternative (i)
or (ii) above be employed will be determined by MQ in its sole discretion with
the approval of the Company, such approval not to be unreasonably withheld.
 
   
    The Rolled Shares to be converted into the Converted Shares pursuant to the
above paragraph will be determined, and the Converted Shares will be distributed
to each of the Rotko Entities, based on their pro rata ownership of MEDIQ
Preferred Stock; provided, however, that the Rotko Trust may, prior to the fifth
business day prior to the Effective Time, notify MQ in writing of a revised
allocation of Rolled Shares among the Rotko Entities and the allocation of the
Converted Shares among the Rotko Entities, whereby the schedule reflecting the
ownership of shares will be revised to reflect such revised allocation (so long
as the aggregate number of Rolled Shares converted into the aggregate number of
Converted Shares and the aggregate number of Converted Shares distributed in
respect of the Rolled Shares remains unchanged) (the "Reallocation"); provided
further, that the Reallocation will not adversely affect the accounting
treatment or the economic impact of the Merger and related transactions to MQ,
the Surviving Corporation and their stockholders other than the Rotko Entities.
    
 
    The Rollover Agreement will terminate immediately upon the termination of
the Merger Agreement if the Merger Agreement is terminated prior to the
Effective Time; provided, that if the termination of the Merger Agreement
results from a failure of the condition relating to performance of the Rollover
Agreement to be satisfied, such termination shall not derogate from MQ's rights
under the Rollover Agreement. The obligations of the parties to the Rollover
Agreement are subject to the execution of a definitive Equity Holders Agreement
reasonably satisfactory to the parties embodying terms substantially as set
forth in Exhibit I to the Rollover Agreement.
 
   
    The Equity Holders Agreement will provide for the following: (i) if BRS
sells (other than to affiliates, coinvestors and other similar parties) or has
redeemed more than 10% of its original investment in Series B Preferred Stock,
the Rotko Entities will have the right to participate on same terms and
conditions pro rata with BRS and other holders of Series B Preferred Stock;
provided, that if such sale or redemption is to or by the Company or any person
related to the Company within the meaning of Section 351(g)(3)(B) of the Code
(the Company and such a related person referred to herein as a "Disqualified
Person"), then BRS and/or its coinvestors, their respective affiliates or a
third party designated by BRS (other than to a Disqualified Person) will offer
to purchase such shares in lieu of the Disqualified Person and any such purchase
will not be directly or indirectly funded by a Disqualified Person; (ii) if
holders of a majority of Series B Preferred Stock propose to sell their shares,
they may elect to cause the Rotko Entities
    
 
                                      127
<PAGE>
to sell their shares on the same terms and conditions and the Rotko Entities
will consent to, and waive any objections with respect to, such transaction;
provided that, if such sale is to a Disqualified Person, BRS and/or its
coinvestors, their respective affiliates or a third party designated by BRS
(other than to a Disqualified Person) will have the right to purchase such
shares in lieu of the Disqualified Person and any such purchase will not be
directly or indirectly funded by a Disqualified Person; and if the Company
redeems shares of the Series A Preferred Stock or Series C Preferred Stock, BRS
and/or its coinvestors, their respective affiliates or a third party designated
by BRS (other than to a Disqualified Person) will offer to purchase (the
"Purchase Option") from the Rotko Entities a percentage of the Series B
Preferred Stock held by them equal to the aggregate liquidation preference of
the Series A Preferred Stock or Series C Preferred Stock so redeemed (not
including any redemption of Series A Preferred Stock issued as Merger
Consideration) divided by the sum of the aggregate liquidation preference of the
Series A, B and C Preferred Stock then outstanding plus the original cost of the
shares of Surviving Corporation Common Stock then outstanding; it being
understood that (a) the intent of the foregoing provision is to provide the
Rotko Entity with a similar investment opportunity as if they converted on the
same terms as BRS and its coinvestors and acquired shares of Series A Preferred
Stock, Series B Preferred Stock, Series C Preferred Stock and Surviving
Corporation Common Stock in the same proportions as BRS and other coinvestors
selected by BRS, (b) a purchase pursuant to the Purchase Option shall not be
directly or indirectly funded by a Disqualified Person and (c) the purchase
price pursuant to the Purchase Option for the Series B Preferred Stock shall be
in an amount not less than the par value plus accrued dividends on such stock
and shall be paid in comparable consideration to that offered to the redeeming
stockholders.
 
    The Equity Holders Agreement will provide that, if the Company proposes to
sell any equity securities, then the holders of the Series B Preferred Stock
will have an opportunity to purchase a proportionate amount of such equity
securities on the same terms and conditions as offered by the Company (in the
ratio of their equity ownership in the Company over the total equity in the
Company prior to the sale), unless such equity securities are issued (a) in
connection with a business combination (unanimously approved by Company's Board
of Directors), (b) to the Company's management or directors, (c) in connection
with debt financing or a bona fide public offering or (d) subject to certain
other exceptions to be negotiated.
 
   
    For the five year period beginning at the Effective Time, the Rotko Entities
will not be permitted to transfer their Series B Preferred Stock or their
Surviving Corporation Common Stock other than to family members and others by
the law of descent distribution or trusts for the benefit of such persons. For
the five-year period beginning on the fifth anniversary of the Effective Time
and ending on the tenth anniversary of the Effective Time, the Rotko Entities
may transfer their shares of Series B Preferred Stock and Surviving Corporation
Common Stock subject to the restrictions applicable to such shares. After the
tenth anniversary of the Effective Time, the Rotko Entities may transfer their
shares of Series B Preferred Stock and Surviving Corporation Common Stock free
of the restrictions applicable to such shares.
    
 
   
    The Equity Holders Agreement will provide that the Rotko Trust will have the
right to designate one director of the Surviving Corporation so long as the
Rotko Entities collectively own 5% of the Surviving Corporation Common Stock.
The Rotko Trust has advised the Company that it will initially designate Michael
J. Rotko to serve as a director of the Surviving Corporation.
    
 
   
    The Equity Holders Agreement will provide that if BRS proposes to sell 10%
or more of its Surviving Corporation Common Stock to a third party, then the
Rotko Entities will have the right to participate on the same terms and
conditions pro rata with BRS and other holders of the Surviving Corporation
Common Stock subject to certain exceptions to be negotiated. The Equity Holders
Agreement will provide that if the holders of a majority of the Surviving
Corporation Common Stock propose to sell their shares to a third party, they may
elect to cause the Rotko Entities to sell their shares of Surviving Corporation
Common Stock on the same terms and conditions and the Rotko Entities will
consent to, and waive any objections with respect to, such transaction. These
"tag-along" and "drag-along" rights relating to the Surviving Corporation Common
Stock will terminate immediately prior to such time as there is a bona fide
public offering of the Surviving Corporation Common Stock.

    additional trusts established by the late Dr. Rotko for the benefit of

                              REGULATORY APPROVALS
 
    The Merger is subject to the expiration or termination of the applicable
waiting period under the HSR Act. Certain aspects of the Merger will require
notification to, and filings with, certain securities and other authorities in
certain states, including jurisdictions where the Company currently operates.
 
    Under the HSR Act and the rules promulgated thereunder by the FTC, the
Merger may not be consummated until notifications have been given and certain
information has been furnished to the FTC and the Antitrust Division and the
applicable waiting period has expired or been terminated. On February 10, 1998,
the Company and BRS each filed a notification report together with requests for
early termination of the waiting period under the HSR Act with the FTC and the
Antitrust Division in respect of the Merger and the related transactions. On
February 24, 1998, the FTC and the Antitrust Division granted early termination
of the waiting period under the HSR Act with respect to the Merger effective
immediately. At any time before or after consummation of the Merger,
notwithstanding termination of the waiting period under the HSR Act, the
Antitrust Division or the FTC could take such action under the antitrust laws as
it deems necessary or desirable in the public interest, including seeking to
enjoin the consummation of the Merger or seeking divestiture of substantial
assets of the Company. At any time before or after the Effective Time, and
notwithstanding termination of the waiting period under the HSR Act, any state
could take such action under the antitrust laws as it deems necessary or
desirable in the public interest. Such action could include seeking to enjoin
the consummation of the Merger or seeking divestiture of substantial assets of
the Company. Private parties may also seek to take legal action under the
antitrust laws under certain circumstances.
 
    Based on information available to them, the Company and MQ 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 a challenge were
made, the Company and MQ would prevail or would not be required to accept
certain adverse conditions in order to consummate the Merger.
 
    The obligations of MQ under the Merger Agreement are also subject to the
receipt of all necessary licenses, permits, consents, approvals, authorizations,
qualifications and orders of governmental authorities and other third parties as
are necessary in connection with the transactions contemplated by the Merger
unless the failure to so obtain would not have a material adverse effect on the
Company and its subsidiaries, taken as a whole.
 
                        DISSENTING STOCKHOLDERS' RIGHTS
 
    If the Merger is consummated, stockholders of the Company who make the
demand described below with respect to their shares, who continuously are the
record holders of such shares through the Effective Time, who otherwise comply
with the statutory requirements of Section 262 (a copy of which is attached
hereto as Annex C to this Proxy Statement/Prospectus) and who neither vote in
favor of the Merger Agreement nor consent thereto in writing will be entitled to
an appraisal by the Delaware Court of the fair value of their shares of MEDIQ
Stock. Except as set forth herein, stockholders of the Company will not be
entitled to appraisal rights in connection with the Merger.
 
    A holder of shares of MEDIQ Stock wishing to exercise dissenters' rights of
appraisal must, before the taking of the vote on the Merger at the Special
Meeting, deliver to the Company a written demand for appraisal of such shares. A
demand for appraisal will be sufficient if it reasonably informs the Company of
the identity of the stockholder and that the stockholder intends thereby to
demand the appraisal of his or her shares.
 
   
    Within 10 days after the Effective Time, the Company is required to, and
will, notify each stockholder of the Company who has satisfied the foregoing
conditions of the date on which the Merger became effective. Within 120 days
after the Effective Time, either the Company or any stockholder who has
    
 
                                      132
<PAGE>
complied with the required conditions of Section 262 may file a petition in the
Delaware Court, with a copy served on the Company in the case of a petition
filed by a stockholder, demanding a determination of the fair value of the
shares of all dissenting stockholders. There is no present intent on the part of
the Company to file an appraisal petition and stockholders seeking to exercise
appraisal rights should not assume that the Company will file such a petition or
that the Company will initiate any negotiations with respect to the fair value
of such shares. Accordingly, stockholders who desire to have their shares
appraised should initiate any petitions necessary for the perfection of their
appraisal rights within the time periods and in the manner prescribed in Section
262. Within 120 days after the Effective Time, any stockholder who has
theretofore complied with the applicable provisions of Section 262 will be
entitled, upon written request, to receive from the Company, a statement setting
forth the aggregate number of shares of MEDIQ Stock not voted in favor of the
Merger Agreement and with respect to which demands for appraisal have been
received by the Company and the aggregate number of holders of such shares. Such
statement must be mailed within 10 days after the written request therefor has
been received by the Company or within 10 days after expiration of the period
for the delivery of demands for appraisal, whichever is later.
 
    If a petition for an appraisal is timely filed, at the hearing on such
petition, the Delaware Court will determine which stockholders are entitled to
appraisal rights. The Delaware Court may require the stockholders who have
demanded an appraisal for their shares and who hold stock represented by
certificates to submit their certificates of stock to the Register in Chancery
for notation thereon of the pendency of the appraisal proceedings; and if any
stockholder fails to comply with such direction, the Delaware Court may dismiss
the proceedings as to such stockholder. Where proceedings are not dismissed, the
Delaware Court will appraise the shares of MEDIQ Stock, owned by such
stockholders, determining the fair value of such shares exclusive of any element
of value arising from the accomplishment or expectation of the Merger, together
with a fair rate of interest, if any, to be paid upon the amount determined to
be the fair value. In determining fair value, the Delaware Court is to take into
account all relevant factors. In WEINBERGER V. UOP INC., the Delaware Supreme
Court discussed the factors that could be considered in determining fair value
in an appraisal proceeding, stating that "proof of value by any techniques or
methods which are generally considered acceptable in the financial community and
otherwise admissible in court" should be considered, and that "fair price
obviously requires consideration of all relevant factors involving the value of
a company." The Delaware Supreme Court stated that in making this determination
of fair value the court must consider market value, asset value, dividends,
earnings prospects, the nature of the enterprise and any other facts which could
be ascertained as of the date of the Merger which throw light on future
prospects of the merged corporation. In WEINBERGER, the Delaware Supreme Court
stated that "elements of future value, including the nature of the enterprise,
which are known or susceptible of proof as of the date of the Merger and not the
product of speculation, may be considered." Section 262, however, provides that
fair value is to be "exclusive of any element of value arising from the
accomplishment or expectation of the Merger."
 
    Holders of shares of MEDIQ Stock considering seeking appraisal should
recognize that the fair value of their shares determined under Section 262 could
be more than, the same as or less than the consideration they are entitled to
receive pursuant to the Merger Agreement if they do not seek appraisal of their
shares. The cost of the appraisal proceeding may be determined by the Delaware
Court and taxed against the parties as the Delaware Court deems equitable in the
circumstances. Upon application of a dissenting stockholder of the Company, the
Delaware Court may order that all or a portion of the expenses incurred by any
dissenting stockholder in connection with the appraisal proceeding, including
without limitation, reasonable attorney's fees and the fees and expenses of
experts, be charged pro rata against the value of all shares of stock entitled
to appraisal.
 
    From and after the Effective Time, no stockholder who has demanded appraisal
rights in compliance with the requirements of Section 262 of the DGCL will be
entitled to vote such stock for any purpose or to
 
                                      133
<PAGE>
receive such stock for any purpose or to receive payment of dividends or other
distributions on the stock (except dividends or other distributions that were
payable to record holders prior to the Effective Time).
 
    At any time within 60 days after the Effective Time, any stockholder will
have the right to withdraw such demand for appraisal and to accept the terms
offered in the Merger; after this period, the stockholder may withdraw such
demand for appraisal only with the consent of the Company. If no petition for
appraisal is filed with the Delaware Court within 120 days after the Effective
Time, stockholders' rights to appraisal will cease, and all holders of shares of
MEDIQ Stock will be entitled to receive the consideration offered pursuant to
the Merger Agreement. Inasmuch as the Company has no obligation to file such a
petition, and the Company has no present intention to do so, any holder of
shares of MEDIQ Stock who desires such a petition to be filed is advised to file
it on a timely basis. Any stockholder may withdraw such stockholder's demand for
appraisal by delivering to the Company a written withdrawal of his or her demand
for appraisal and acceptance of the Merger, except (i) that any such attempt to
withdraw made more than 60 days after the Effective Time will require written
approval of the Company, and (ii) that no appraisal proceeding in the Delaware
Court will be dismissed as to any stockholder without the approval of the
Delaware Court, and such approval may be conditioned upon such terms as the
Delaware Court deems just.
 
    The foregoing is only a summary of Section 262, and is qualified in its
entirety by reference to the provisions thereof, the full text of which is set
forth as Annex C to this Proxy Statement/Prospectus. Each stockholder of the
Company is urged to read carefully the full text of Section 262.

                          AGREEMENT AND PLAN OF MERGER
 
    THIS AGREEMENT AND PLAN OF MERGER (the "Agreement"), dated as of January 14,
1998, is by and between MQ ACQUISITION CORPORATION, a Delaware corporation
("Acquiror"), and MEDIQ INCORPORATED, a Delaware corporation (the "Company").
 
    WHEREAS, the respective Boards of Directors of the parties hereto have each
approved, upon the terms and subject to the conditions set forth in this
Agreement, the merger of Acquiror with and into the Company (the "Merger"),
pursuant to which each issued and outstanding share of common stock, par value
$1.00 per share, of the Company (a "Common Share") and each issued and
outstanding share of Series A Preferred Stock, par value $.50 per share, of the
Company (a "Preferred Share"; the Common Shares and the Preferred Shares are
sometimes referred to herein collectively as the "Shares"), will be converted
into the right to receive (i) $13.75 per Share net to the stockholder in cash,
without interest, and (ii) 0.075 shares of Series A 13% Cumulative Compounding

the Company and Dissenting Shares (as defined in Section 1.6(b)); and
 
    WHEREAS, the respective Boards of Directors of the Company and Acquiror have
determined that the Merger would be fair and in the best interests of their
respective stockholders; and
 
    WHEREAS, the Merger and this Agreement require for the approval thereof (i)
the affirmative vote of the holders of a majority of the outstanding voting
power of the Shares, voting together as a single class and (ii) the affirmative
vote of the holders of a majority of the outstanding Preferred Shares (the
"Company Stockholder Approvals"); and
 
    WHEREAS, Acquiror is unwilling to enter into this Agreement unless,
contemporaneously with the execution and delivery of this Agreement, certain
beneficial and record stockholders of the Company enter into agreements
(collectively, the "Stockholders Agreement") providing for certain actions
relating to the transactions contemplated by this Agreement and agreements
(collectively, the "Option Agreement") providing Acquiror with the option to
acquire the Shares owned by such persons and entities on the terms and
conditions set forth in the Option Agreement; and in order to induce Acquiror to
enter into this Agreement, the Company has approved the entering into by
Acquiror and such stockholders of the Stockholders Agreement and the Option
Agreement, and such stockholders have agreed to enter into, execute and deliver
the Stockholders Agreement and the Option Agreement; and
 
    WHEREAS, Acquiror is unwilling to enter into this Agreement unless,
contemporaneously with the execution and delivery of this Agreement, certain
beneficial and record stockholders of the Company (the "Rotko Entities") enter
into agreements to roll over certain Shares (the "Rotko Rollover Shares") owned
by such persons into securities of the Company, on the terms set forth on
Exhibit B hereto (the "Rollover Agreement"); and
 
    WHEREAS, it is intended that the Merger be recorded as a recapitalization
for financial reporting purposes.
 
    NOW, THEREFORE, in consideration of the foregoing premises and the
representations, warranties and agreements contained herein, the parties hereto
agree as follows:

the Merger to be consummated by filing with the Secretary of State of the State
of Delaware a certificate of merger (the "Certificate of Merger") in such form
as may be required by, and executed and acknowledged in accordance with, the
DGCL. The parties hereto shall cause the effective date of the Merger (the
"Effective Date") to occur on the date that the Certificate of Merger is filed
with the Secretary of State of the State of Delaware in accordance with the DGCL
(or at such later time, which shall be as soon as reasonably practicable, as may
be specified in the Certificate of Merger). The time on the Effective Date when
the Merger shall become effective is referred herein to as the "Effective Time."
    
 
    SECTION 1.3 EFFECTS OF THE MERGER.  At the Effective Time, the separate
corporate existence of Acquiror shall cease, and the Surviving Corporation shall
continue its corporate existence under the laws of the State of Delaware and the
Merger shall have the effects set forth in the applicable sections of the DGCL.
 
    SECTION 1.4 ARTICLES OF INCORPORATION; BYLAWS; DIRECTORS AND OFFICERS.
 
    (a) At the Effective Time, the Certificate of Incorporation of Acquiror
(which Acquiror shall amend prior to the Effective Time in order to provide for
the Senior Preferred Shares, on the terms set forth on Exhibit A, and the Series
B Preferred Stock and the Series C Preferred Stock, on the terms set forth on
Exhibit B hereto, and to otherwise effect the transactions contemplated by this
Agreement), as in effect immediately prior to the Effective Time, shall be the
Certificate of Incorporation of the Surviving Corporation until thereafter
amended (subject to the restrictions set forth in Section 4.2(c) hereof) in
accordance with applicable law. Acquiror shall not amend its Certificate of
Incorporation or Bylaws prior to the Effective Time, pursuant to the previous
sentence or otherwise, without the consent of the Company, not to be
unreasonably withheld.
 
    (b) At the Effective Time, the Bylaws of Acquiror as in effect immediately

4.2(c) hereof) in accordance with applicable law.
 
    (c) The directors of Acquiror immediately prior to the Effective Time shall
be the initial directors of the Surviving Corporation in each case until their
successors are elected or appointed and qualified.
 
    (d) The officers of the Company immediately prior to the Effective Time

their successors are elected or appointed and qualified.
 
    SECTION 1.5 MERGER CONSIDERATION; CANCELLATION OF SHARES.  Upon the terms
and subject to the conditions of this Agreement, at the Effective Time,
automatically by virtue of the Merger and without any further action on the part
of any party hereto or the holders of any of the following securities:
 
    (a) Each Share issued and outstanding immediately prior to the Effective
Time, other than Shares cancelled pursuant to Section 1.5(b) and Dissenting
Shares (as defined in Section 1.6(b)), shall be
 
                                      A-5
<PAGE>
converted into and become the right to receive, (i) $13.75 in net cash per Share
without any interest thereon and (ii) 0.075 shares of Senior Preferred Stock
(collectively, the "Merger Consideration").
 
    (b) Each Share that is issued and outstanding immediately prior to the
Effective Time and owned by the Acquiror or the Company or any direct or
indirect subsidiary of the Acquiror or the Company, shall be cancelled,
extinguished and retired, and no payment of any consideration shall be made with
respect thereto.
 
    (c) As a result of their conversion pursuant to Section 1.5(a), all Shares
(excluding any Shares described in Section 1.5(b), and any Dissenting Shares)
issued and outstanding immediately prior to the Effective Time shall cease to be
outstanding and shall automatically be cancelled and retired, and each
certificate ("Certificate") previously evidencing such Shares ("Converted
Shares") shall thereafter solely represent the right to receive the Merger
Consideration pursuant to Section 1.5(a) of this Agreement. The holders of
Certificates shall cease to have any rights with respect to such Converted
Shares except as otherwise provided herein or by law.
 
    (d) Each share of capital stock of Acquiror issued and outstanding
immediately prior to the Effective Time (including any shares of capital stock
issued by Acquiror in exchange for the Rotko Rollover Shares) shall be converted
into and thereafter represent the same number of shares of the same class of
capital stock of the Surviving Corporation, provided that, each of the Rotko
Rollover Shares not owned by the Acquiror immediately prior to the Effective
Time shall be converted into and thereafter represent the number of shares of
capital stock of the Surviving Corporation as set forth in the Rollover
Agreement.
 
    SECTION 1.6 DISSENTING SHARES.
 
    (a) Notwithstanding any provision of this Agreement to the contrary, any
Shares held by a holder (a "Dissenting Shareholder") who has timely demanded and
perfected his demand for appraisal of his Shares in accordance with Section 262
of the DGCL and as of the Effective Time has neither effectively withdrawn nor
lost his right to such appraisal shall not represent a right to receive Merger
Consideration for such Shares pursuant to Section 1.5 above, but rather the
holder thereof shall be entitled to only such rights as are granted by the DGCL.
 
    (b) If any Dissenting Shareholder demanding appraisal of such Dissenting
Shareholder's Shares ("Dissenting Shares") under the DGCL shall effectively
withdraw or lose (through failure to perfect or otherwise) his right to
appraisal, then as of the Effective Time or the occurrence of such event,
whichever later occurs, such Dissenting Shares shall automatically be converted
into and represent only the right to receive the Merger Consideration with
respect to such Shares as provided in Section 1.5 above upon surrender of the
Certificate or Certificates representing such Dissenting Shares in accordance
with this Agreement.
 
    (c) The Company shall give Acquiror prompt notice of any demands by a
Dissenting Shareholder for payment or notices of intent to demand payment
received by the Company under Section 262 of the DGCL and Acquiror shall have
the right to participate in and direct all negotiations and proceedings with
respect to such demands. The Company shall not, except with the prior consent of
Acquiror or as otherwise required by law, make any payment with respect to, or
settle, or offer to settle, any such demands.
 
    SECTION 1.7 STOCK OPTIONS.
 
    (a) Upon the consummation of the Merger, each option to acquire Shares
outstanding immediately prior to the Effective Time under the Company's stock
option plans or similar arrangements (as listed in Schedule 1.7(a)), whether
vested or unvested (each, an "Option," and collectively, the "Options"), shall
automatically become immediately exercisable and each holder of an Option shall
have the right to receive from Acquiror in respect of each Share underlying the
Option (less applicable withholding taxes) (i) a cash
 
                                      A-6
<PAGE>
payment in an aggregate amount equal to the difference between the cash portion
of the Merger Consideration of $13.75, less the exercise price per Share
applicable to such Option as stated in the applicable stock option agreement or
other agreement plus (ii) 0.075 share of Senior Preferred Stock (the "Option
Consideration"); provided that, with respect to any person subject to Section 16
of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), no
Option Consideration shall be paid to such person until payment can be made
without liability to such person under Section 16(b) of the Exchange Act. The
Company shall take such other actions (including, without limitation, giving
requisite notices to holders of Options advising them of such accelerated
exercisability and right to obtain payment for their respective Options) as are
necessary to fully advise holders of Options of their rights and to facilitate
their timely exercise of suchrights. From and after the Effective Time, other
than as expressly set forth in this Section 1.7, no holder of an Option shall
have any other rights in respect thereof other than to receive payment for his
or her Options as set forth herein, and the Company shall take all reasonably
necessary actions to terminate the Company's stock option plans and similar
arrangements.
 
    (b) The provisions of Section 1.7(a) shall be subject to the Company
obtaining any required consents from the holders of any Options and the making
of any necessary amendments to the Company's stock option plans and other
similar agreements. The Company shall use its commercially reasonable efforts to
obtain any such consents and make any such amendments. As used in this
Agreement, the requirement that Acquiror, the Company or any Subsidiary (as
defined in Section 2.1(c)) shall use its "commercially reasonable efforts" shall
not include efforts which require the Acquiror, Company or any Subsidiary (i) to
do any act that is commercially unreasonable under the circumstances; (ii) to
amend, waive or release, other than as contemplated by this Agreement, any
material rights in order to obtain approvals or consents; or (iii) except in
connection with the Financing (as defined herein), to provide guarantees or to
post any collateral.
 
    SECTION 1.8 SURRENDER OF SECURITIES; FUNDING OF PAYMENTS; STOCK TRANSFER
     BOOKS.
 
    (a) Prior to the Effective Time, Acquiror shall designate a bank or trust
company to act as agent for the holders of the Shares and Options (the "Exchange
Agent") for the purpose of exchanging Certificates for the Merger Consideration
and documents representing Options (the "Option Agreements") for the Option
Consideration. The fees and expenses of the Exchange Agent shall be paid by the
Company.
 
    (b) At the Effective Time, Acquiror shall remit (or cause to be remitted) to
the Exchange Agent, for the benefit of the holders of the Shares and Options, an
amount equal to the aggregate cash portion of the Merger Consideration and the
Option Consideration and a number of Shares of Senior Preferred Stock equal to
the aggregate portion of the Merger Consideration and Option Consideration
necessary to pay the holders of the Shares and Options pursuant to Sections 1.5
and 1.7 (the "Payment Fund").
 
    (c) As soon as practicable after the Effective Time and in no event later
than ten business days thereafter, the Surviving Corporation shall cause the
distribution to holders of record of the Certificates and Option Agreements (as
of the Effective Time) of (i) notice of the effectiveness of the Merger and (ii)
a form of letter of transmittal and other appropriate materials and instructions
for use in effecting the surrender of the Certificates for payment of the Merger
Consideration therefor and in effecting the surrender of the Option Agreements
for payment of the Option Consideration therefor. In the event any Certificate
or Option Agreement shall have been lost or destroyed, the Exchange Agent shall
be authorized to accept an affidavit from the record holder of such Certificate
or the party to such Option Agreement in a form reasonably satisfactory to
Acquiror, subject to other conditions as Acquiror may reasonably impose
(including the posting of an indemnity bond or other surety). Upon the surrender
of each such Certificate, together with such letter of transmittal, duly
completed and validly executed in accordance with the instructions thereto, the
Exchange Agent shall pay out of the Payment Fund the Merger Consideration to the
holders of such Certificates, less any amounts required to be withheld pursuant
to applicable tax laws. Upon the surrender of Option Agreements formerly
representing Options, together with a letter of transmittal, duly completed and
validly executed in accordance with the
 
                                      A-7
<PAGE>
instructions thereto, the Exchange Agent shall pay the Option Consideration to
the holders of such Option Agreements, less any amounts required to be withheld
pursuant to applicable tax laws. The Exchange Agent shall accept such
Certificates and Option Agreements upon compliance with such reasonable terms
and conditions as the Exchange Agent may impose to effect an orderly exchange
thereof in accordance with normal exchange practices. Until surrendered as
contemplated by this Section 1.8(c), (i) each Certificate shall be deemed at any
time after the Effective Time to represent only the right to receive upon such
surrender the Merger Consideration as contemplated by Section 1.5, and (ii) each
Option Agreement shall be deemed at any time after the Effective Time to
represent only the right to receive upon such surrender the Option Consideration
as contemplated by Section 1.7. No interest will be paid or will accrue on any
cash payable as Merger Consideration or in lieu of any fractional shares of
Senior Preferred Stock, as the case may be.
 
    (d) If any portion of the Cash Merger Consideration or Option Consideration
is to be paid or any certificate representing shares of Senior Preferred Stock
is to be issued to a person other than the person in whose name a cancelled
Certificate or Option Agreement is registered, it shall be a condition to such
payment or issuance that such cancelled Certificate or Option Agreement shall be
surrendered and shall be properly endorsed or shall be otherwise in proper form
for transfer and that the person requesting such payment shall have paid any
transfer and other taxes required by reason of such payment in a name other than
that of the registered holder of the certificate or instrument surrendered or
shall have established to the reasonable satisfaction of Acquiror and the
Exchange Agent that such tax either has been paid or is not payable.
 
    (e) After the Effective Time of the Merger, there shall be no further
transfer on the records of the Company or its transfer agent of Certificates
representing Shares which have been converted, in whole or in part, pursuant to
this Agreement into the right to receive the Merger Consideration, and if such
Certificates are presented to the Company for transfer, they shall be cancelled
against delivery of cash and Certificates for Shares of Senior Preferred Stock
as provided herein.
 
    (f) To the extent not immediately required for payment with respect to
surrendered Shares and Options, proceeds in the Payment Fund shall be invested
by the Exchange Agent as directed by the Surviving Corporation (as long as such
directions do not impair the rights of holders of Shares or Options), in direct
obligations of the United States of America, obligations for which the faith and
credit of the United States of America is pledged to provide for the payment of
principal and interest, commercial paper rated of the highest investment quality
by Moody's Investors Service, Inc. or Standard & Poor's Ratings Services, or
certificates of deposit issued by a commercial bank having at least $5 billion
in assets, and any net earnings with respect thereto shall be paid to the
Surviving Corporation as and when requested by the Surviving Corporation.
 
    (g) No dividends or other distributions with a record date after the
Effective Time shall be paid to the holder of any unsurrendered Certificate with
respect to the shares of Senior Preferred Stock represented thereby and no cash
payment in lieu of fractional shares shall be paid to any such holder pursuant
to Section 1.8(j) until the surrender of such Certificate in accordance with
this Section 1.8. Subject to the effect of applicable laws, following surrender
of any such Certificate, there shall be paid to the holder of the Certificate
representing whole shares of Senior Preferred Stock issued in connection
therewith, without interest, (i) at the time of such surrender or as promptly
thereafter as practicable, the amount of any cash payable in lieu of a
fractional share of Senior Preferred Stock to which such holder is entitled
pursuant to Section 1.8(j) and the proportionate amount of dividends or other
distributions with a record date after the Effective Time of the Merger
theretofore paid with respect to such whole number of shares of Senior Preferred
Stock, and (ii) at the appropriate payment date, the proportionate amount of
dividends or other distributions with a record date after the Effective Time but
prior to such surrender and a payment date subsequent to such surrender payable
with respect to such whole number of shares of Senior Preferred Stock.
 
                                      A-8
<PAGE>
    (h) After the Effective Time, holders of Certificates shall cease to have
any rights as stockholders of the Company, except as provided herein or under
the DGCL. All cash paid and shares of Senior Preferred Stock issued upon the
surrender for exchange of Certificates in accordance with the terms of this
Section 1.8 (including any cash paid pursuant to Section 1.8(j)) shall be deemed
to have been issued (and paid) in full satisfaction of all rights pertaining to
the Shares exchanged theretofore represented by such Certificates. No interest
shall be paid on any Merger Consideration or Option Consideration payable to
former holders of Shares or Options.
 
    (i) Promptly following the one-year anniversary date of the Effective Date,
the Exchange Agent shall return to the Surviving Corporation all cash and shares
of Senior Preferred Stock in its possession out of the Payment Fund relating to
the transactions described in this Agreement, and the Exchange Agent's duties
shall terminate. Thereafter, each holder of a Certificate or an Option Agreement
shall look only to the Surviving Corporation and only as general creditors
thereof for payment of their claims for the Merger Consideration and the Option
Consideration, including any cash in lieu of fractional shares of Senior
Preferred Stock and any dividends or distributions with respect to such shares
to which such holders may be entitled, and each such holder of a Certificate or
an Option Agreement may surrender the same to the Surviving Corporation and upon
such surrender (subject to applicable abandoned property, escheat or similar
laws) the Surviving Corporation shall deliver to such holder the Merger
Consideration and/or Option Consideration with respect to such shares or
Options, as applicable.
 
    (j) No certificates or scrip representing fractional shares of Senior
Preferred Stock shall be issued in connection with the Merger, and such
fractional share interests will not entitle the owner thereof to vote or to any
rights of a stockholder of the Surviving Corporation after the Merger. Each
holder of Shares exchanged pursuant to the Merger who would otherwise have been
entitled to receive a fractional Senior Preferred Share (after taking into
account all Shares delivered by such holder) shall receive, in lieu thereof, a
cash payment (without interest) therefor in an amount equal to the value
(determined with reference to the Liquidation Value of such Senior Preferred
Share) of such fractional share provided that such cash payments do not exceed
$50,000 in the aggregate. If such cash payments exceed $50,000, each holder of
Shares exchanged pursuant to the Merger who would otherwise have been entitled
to receive a fractional Share Senior Preferred Stock (after taking into account
all Shares delivered by such holder) shall receive, in lieu thereof, a cash
payment (without interest) representing such holder's proportionate interest in
the net proceeds from the sale by the Exchange Agent (following the deduction of
applicable transaction costs), on behalf of all such holders, of the Senior
Preferred Stock (the "Excess Shares") representing such fractions. Such sale
shall be made as soon as practicable after the Effective Time.
 
    (k) None of Acquiror, the Company, their respective affiliates, or the
Exchange Agent shall be liable to any person in respect of any shares of Senior
Preferred Stock (or dividends or distributions with respect thereto) or cash
from the Payment Fund delivered to a public official pursuant to any applicable
abandoned property, escheat or similar law. If any Certificates or Option
Agreements shall not have been surrendered prior to three years after the
Effective Time (or immediately prior to such earlier date on which any cash, if
any, in lieu of fractional shares of Senior Preferred Stock would otherwise
escheat to or become the property of any Governmental Entity (as defined
below)), any such cash, dividends or distributions in respect of such
Certificates and Option Agreements shall, to the extent permitted by applicable
law, become the property of the Company, free and clear of all claims or
interest of any person previously entitled thereto.
 
    SECTION 1.9. SUBSEQUENT 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 either of the Company or Acquiror acquired or to be
acquired by the Surviving Corporation as a result of, or in connection with, the
Merger 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 either the
 
                                      A-9
<PAGE>
Company or Acquiror, all such deeds, bills of sale, assignments and assurance
and to take, in the name and on behalf of each of such corporations or
otherwise, 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 in the Surviving Corporation or otherwise to
carry out the transactions contemplated by this Agreement.
 
    SECTION 1.10 ADJUSTMENT OF MERGER CONSIDERATION AND OPTION
CONSIDERATION.  The Merger Consideration payable pursuant to Section 1.5(a) and
the Option Consideration payable pursuant to Section 1.7 have been calculated
based upon the representations and warranties made by the Company in Section
2.2. In the event that, at the Effective Time, the actual number of Shares
outstanding and/or the actual number of Shares issuable upon the exercise of
outstanding options, warrants or similar agreements or upon conversion of
securities (including without limitation, as a result of any stock split, stock
dividend, including any dividend or distribution of securities convertible into
Shares, or a recapitalization) is more than as described in Section 2.2, the
Merger Consideration and the Option Consideration shall be appropriately
adjusted downward; provided that, no adjustment shall be made pursuant to this
Section 1.10 unless, at the Effective Time, the actual number of Shares
outstanding plus the actual number of Shares issuable upon the exercise of all
such options, warrants or similar agreements or upon the conversion of
securities is more than 20,000 more than as described pursuant to Section 2.2.
The provisions of this Section 1.10 shall not, in any event, derogate from the
representation and warranty set forth in Section 2.2.
 
                                   ARTICLE II
 
                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY
 
    The Company represents and warrants to Acquiror that:
 
    SECTION 2.1 CORPORATE ORGANIZATION AND AUTHORIZATION.
 
    (a) The Company is a corporation duly incorporated, validly existing and in
good standing under the laws of the State of Delaware and, upon obtaining the
Company Stockholder Approvals, has all requisite corporate power and authority
to, execute and deliver this Agreement and to carry out its obligations
hereunder. (b) (i) The Company has all requisite corporate power and authority
and all governmental authorizations, certificates, licenses, consents and
approvals required to own, lease and operate its properties and to carry on its
business as currently conducted, except where the failure to possess such
authorizations, certificates, licenses, consents and approvals (either
individually or in the aggregate) would not reasonably be expected to have a
Material Adverse Effect on the Company (as defined in Section 2.1(b)(ii)). The
Company is duly qualified or licensed to do business as a foreign corporation
and is in good standing in each jurisdiction where the character of the
properties owned, operated or leased by it or the nature of the activities
conducted by it makes such qualification necessary, except where the failure to
so qualify or be licensed or to maintain such good standing (either in one
jurisdiction or in the aggregate) would not reasonably be expected to have a
Material Adverse Effect on the Company.
 
    (ii) For purposes of this Agreement, "Material Adverse Effect" shall mean
with respect to the Company or Acquiror, as applicable, any change, effect or
event that (i) is material and adverse to the assets, liabilities, condition
(financial or otherwise), cash flows, results of operations or business of the
Company and the Subsidiaries (as defined in Section 2.1(c)) taken as a whole, or
Acquiror and its subsidiaries taken as a whole, respectively, or (ii) materially
impairs the ability of the Company or Acquiror, respectively, to perform its
obligations under this Agreement or otherwise materially threatens or materially
impedes the consummation of the Merger and the other transactions contemplated
by this Agreement or the conduct of the business of the Company or Acquiror, as
the case may be; provided, however, that Material Adverse Effect shall not be
deemed to include the impact of actions or omissions of the Company or Acquiror
taken with the prior written consent of the other in contemplation of the
transactions contemplated hereby.
 
                                      A-10
<PAGE>
    (c) All of the Company's subsidiaries are listed on Schedule 2.1(c) hereto
(the "Subsidiaries"). For purposes of this Agreement, "subsidiary" means any
entity of which securities or other ownership interests having ordinary voting
power to elect a majority of the Board of Directors or other persons performing
similar functions are directly or indirectly owned by such party. All of the
Company's "significant subsidiaries" are marked with an asterisk on Schedule
2.1(c) (the "Significant Subsidiaries"). For purposes of this section,
"significant subsidiary" has the meaning set forth in Rule 1-02(w) of Regulation
S-X of the Securities and Exchange Commission (the "SEC"). Except as set forth
on Schedule 2.1(c), each of the Company's Subsidiaries is wholly owned, directly
or indirectly, by the Company. Schedule 2.1(c) lists the outstanding capital
stock or other equity interests of each Subsidiary and the number of shares or
other equity interests owned by the record holders thereof. Other than bonus
plans and sales commission plans of the Company and the Subsidiaries implemented
by the Company and the Subsidiaries in the ordinary course of business, copies
or descriptions of which have been provided or made available to Acquiror, there
are no agreements, arrangements or commitments of any character (contingent or
otherwise) pursuant to which any person is or may be entitled to receive any
payment based on the revenues or earnings, or calculated in accordance
therewith, of the Company or any Subsidiary. There are no voting trusts, proxies
or other agreements or understandings to which the Company or any Subsidiary is
a party or by which the Company or any Subsidiary is bound with respect to the
voting of any shares of capital stock of the Company or any Subsidiary. Except
as set forth on Schedule 2.1(c), the Company and its Subsidiaries (i) do not
directly or indirectly own, (ii) have not agreed to purchase or otherwise
acquire and (iii) do not hold any interest convertible into or exchangeable or
exercisable for, 5% or more of the capital stock or other equity interest of any
corporation, partnership, company, joint venture or other business association
or entity.
 
    (d) Each Subsidiary is a corporation duly organized, validly existing and in
good standing under the laws its jurisdiction of incorporation and has all
requisite corporate power and authority and all governmental authorizations,
certificates, licenses, consents and approvals required to own, lease and
operate its properties and to carry on its business as currently conducted,
except where the failure to possess such authorizations, certificates, licenses,
consents and approvals (either individually or in the aggregate) would not
reasonably be expected to have a Material Adverse Effect on the Company. Each
Subsidiary is duly qualified or licensed to do business as a foreign corporation
and is in good standing in each jurisdiction where the character of the property
owned, operated or leased by it or the nature of the activities conducted by it
makes such qualification necessary, except where the failure to so qualify or be
licensed or to maintain such good standing (either in one jurisdiction or in the
aggregate) would not reasonably be expected to have a Material Adverse Effect on
the Company.
 
    (e) All of the outstanding capital stock of each Subsidiary held by the
Company (i) has been validly issued, is fully paid and nonassessable and is not
subject to preemptive or similar rights and (ii) except as described on Schedule

in connection with the exercise of outstanding Options heretofore granted under
the stock option plans listed in Schedule 1.7(a); and (d) 256,710 Common Shares
and 9,675 Preferred Shares were reserved for issuance and are issuable upon or

any of its Subsidiaries is obligated to issue (or to issue upon the occurrence
of certain events) additional shares of its capital stock, options, warrants or
rights to purchase, redeem or acquire any additional shares of its capital stock
or securities convertible into or exchangeable or exercisable for any such
shares or other securities. Each Preferred Share is convertible into one Common

hereby (except, in the case of consents, approvals, authorizations, filings or
permits with or from persons or entities other than Governmental Entities, where
the failure to make such filings or obtain such consents, approvals, orders,
authorizations or permits would not reasonably be expected to result in a
Material Adverse Effect on the Company.)

accounting principles (except, in the case of unaudited consolidated quarterly

Company and its Subsidiaries as of the dates thereof and the consolidated

financial statements contained in such consolidated financial statements are not
necessarily indicative of the consolidated financial position of Company and its
Subsidiaries as of the respective dates thereof and the consolidated results of
their operations, changes in stockholders' equity and cash flows for the periods
indicated.
 
    (c) The unaudited preliminary financial information reflected on Schedule

recent Company Form 10-K included in the Company Public Reports or as set forth
on Schedule 2.6, (a) there are no claims, actions, suits, proceedings or
investigations pending or, to the Company's knowledge, threatened against the
Company or any Subsidiary or their assets or properties, or with respect to
which the Company or any Subsidiary has retained or assumed responsibility by
contract or operation of law (i) seeking to enjoin, prohibit, restrain or
otherwise prevent the transactions contemplated hereby or (ii) which, if
adversely determined, individually or in the aggregate would reasonably be
expected to result in a Material Adverse Effect on the Company; and (b) there
are no judgments, decrees, orders, writs, injunctions, determinations or awards
issued by any Governmental Entity currently outstanding and unsatisfied against

be expected to have a Material Adverse Effect on the Company.
 
    SECTION 2.7 NO DIVIDENDS OR DISTRIBUTIONS.  Since September 30, 1997 there
has not been any declaration, setting aside or payment of any dividend or any
other distribution with respect to the Company's capital stock or any

    (a) Schedule 2.17 sets forth each parcel of real property owned in fee by
the Company or any of its Subsidiaries (collectively, the "Owned Properties")
and each parcel of real property leased, subleased or licensed by the Company or
any of the Subsidiaries (collectively, the "Leased Properties") (the Owned
Properties and Leased Properties being sometimes referred to herein collectively
as the "Company Properties"). The Company or one of the Subsidiaries has (i)
good and marketable fee title to the Owned Properties and (ii) good and valid
leasehold title or other occupancy right to the Leased Properties, free and
clear of all liens, claims and encumbrances which individually or in the
aggregate would materially impair use of such properties in the Company's
business as they are currently being used.
 
    (b) Each agreement under which the Leased Properties are leased, subleased
or licensed to the Company or its Subsidiaries as of the date hereof
(collectively, the "Company Leases") is in full force and effect in accordance
with its respective terms and the Company or one of the Subsidiaries is the
holder of the lessee's or tenant's interest thereunder and there exists no
default under any of the Company Leases by the Company or any of the
Subsidiaries and no circumstance exists which, with the giving of notice, the
passage of time or both would result in such a default, except for such defaults
or other circumstances which, individually or in the aggregate, have not had and
would not reasonably be expected to have a Material Adverse Effect on the
Company. Except as set forth in Schedule 2.17, the consummation of the Merger
and the transactions contemplated by this Agreement do not and will not violate
the terms of any of the Company Leases except for any violations, individually
or in the aggregate with all other violations, which have not had and would not
reasonably be expected to have a Material Adverse Effect on the Company. Neither
the Company nor any of the Subsidiaries (or any of the affiliates of any of the
 
                                      A-21
<PAGE>
foregoing) has an ownership, financial or other interest in the landlord under

any statutes, laws, regulations, rules, ordinances, permits, requirements,
orders or decrees now in effect except for such violations which, individually
or in the aggregate with all other violations, have not had and could not
reasonably be expected to have a Material Adverse Effect on the Company.
 
    SECTION 2.18 DISCLOSURE.  The representations and warranties of the Company

they were made, not misleading.
 
    SECTION 2.19 BOARD RECOMMENDATION; SECTION 203; REQUIRED VOTE.  (a) The
Special Committee and the Board of Directors of the Company, at a meeting duly
called and held, have each by unanimous vote of those directors present (who
constituted all of the directors then in office) (i) determined that the Merger,
this Agreement and the transactions contemplated hereby are fair to and in the
best interests of the holders of Common Shares, (ii) determined that the Merger,
this Agreement and the transactions contemplated hereby are fair to and in the
best interests of the holders of Preferred Shares, and (iii) recommended that

each approved the execution of this Agreement and the execution of the
Stockholders Agreement and the Option Agreement by the Acquiror and certain
stockholders of the Company prior to the execution of this Agreement in
accordance with Section 203 of the DGCL, so that such Section will not apply to
Acquiror, the Merger, this Agreement, the Stockholders Agreement, the Option
Agreement or the transactions contemplated hereby or thereby. No provision of
the Certificate of Incorporation, bylaws or other governing instruments of the
Company or any of its Subsidiaries would, directly or indirectly, restrict or
impair the ability of Acquiror or its affiliates to vote, or otherwise to
exercise the rights of a stockholder with respect to, securities of the Company
and its Subsidiaries that may be acquired or controlled by Acquiror or its
affiliates or permit any stockholder to acquire securities of the Company on a

the affirmative vote of the holders of a majority of the voting power of the
Common Shares and the Preferred Shares, voting together as a single class, with
the holders of the Common Shares each being entitled to cast one vote for each
Common Share owned of record by such holder and the holders of the Preferred
Shares each being entitled to cast ten votes for each Preferred Share owned of
record by such holder. No other vote of the holders of any class or series of
the Company's securities (including debt securities) is necessary to approve the
Merger, this Agreement or the transactions contemplated hereby and no vote of
the holders of any class or series of the Company's securities is necessary to
approve the Stockholders Agreement.
 
    (d) The execution, delivery and performance of this Agreement, the
Stockholders Agreement, the Option Agreement and the consummation of the
transactions contemplated hereby or thereby will not cause to be applicable to
the Company any state anti-takeover or similar statute or regulation.

employees, representatives and advisors (including the Company's financial

are pending or, to the knowledge of the Company, threatened that the Company is,
and to the knowledge of the Company, neither the Company nor any Subsidiary is,

to any Intellectual Property Right except for claims that have not had and would
not reasonably be expected to result in a Material Adverse Effect on the
Company. To the knowledge of the Company, except as set forth in Schedule 2.21,
no person is infringing the rights of the Company with respect to any
Intellectual Property Right. The Company has not licensed, or otherwise granted,
to any third party, any rights in or to any Intellectual Property Rights.

    SECTION 4.1 CONDUCT OF THE COMPANY PRIOR TO THE EFFECTIVE TIME. EXCEPT AS
OTHERWISE CONSENTED TO BY ACQUIROR:
 
        (a) No Solicitation; Other Offers.
 
        (i) From the date of this Agreement until the termination of this
    Agreement or the Effective Time, whichever first occurs, the Company shall
    not, and shall cause the Subsidiaries not to, and shall use its best efforts
    to cause the officers, directors, employees, affiliates, representatives and
    other agents (including attorneys, investment bankers and accountants) of
    the Company and the Subsidiaries not to, directly or indirectly, solicit,
    initiate or encourage any inquiry, proposal, indication of interest or offer
    from any person that constitutes or would reasonably be expected to lead to
    any Acquisition Proposal (as hereinafter defined) or enter into discussions
    or negotiate with any person or entity in furtherance of any such inquiries,
    proposals, indications of interest or offers or to obtain or approve any
    Acquisition Proposal, or agree to or endorse any Acquisition Proposal, and
    the Company shall immediately notify Acquiror of all relevant terms of any
    such inquiries, proposals, indications of interest or offers received by the
    Company or any Subsidiary or by any such officer, director, employee,
    affiliate, representative or agent, relating to any of such matters, any
    material change in the details (including any amendments or proposed
    amendments) of any such inquiries, proposals, indications of interest or
    offers, the identity of each of the persons or entities making such
    inquiries, proposals, indications of interest or offers, and, if any such
    inquiry, proposal, indication of interest or offer is in writing, the
    Company shall immediately deliver a copy thereof to Acquiror; provided,
    however, that if, prior to the Effective Time, the Company shall receive an
    Acquisition Proposal (that was not solicited after January 9, 1998), from a
    New Bidder (as defined below) that the Board of Directors of the Company,
    after receiving the written advice of its legal counsel, reasonably believes
    that it has a fiduciary duty to consider, then the Company, without
    violating this Agreement, may thereafter furnish information to and enter
    into discussions or negotiations with such New Bidder making such
    Acquisition Proposal; provided that, before furnishing any information to,
    or entering into discussions or negotiations with, any such New Bidder, the
    Company shall have obtained an executed confidentiality agreement containing
    confidentiality, "standstill" and other customary terms and conditions no
    less favorable to the Company than the terms and conditions of the
    Confidentiality Agreement (as defined in Section 9.5). Neither the Board of
    Directors of the Company, nor any committee thereof, shall (A) withdraw or
    modify, in a manner adverse to Acquiror, the approval or recommendation by
    the Board of Directors or any such committee thereof of this Agreement or
    the Merger, (B) approve or recommend any Acquisition Proposal, (C) enter
    into any agreement with respect to any Acquisition Proposal, (D) take any
    action to facilitate any other Acquisition Proposal in any respect, or (E)
    terminate this Agreement in connection with any Acquisition Proposal;
    provided that, nothing contained in this Section 4.1(a) or any other
    provision of this Agreement shall prevent the Board of Directors or any
    committee thereof, after receiving an Acquisition Proposal as described in
    the immediately preceding sentence that, after receiving the written advice
    of its legal counsel, the Board of Directors reasonably believes that it has
    a fiduciary duty to consider, from considering, negotiating, approving or
    recommending to the stockholders of the Company such an Acquisition Proposal
    from a New Bidder, provided that the Board of Directors of the Company
    reasonably determines (after consultation with its financial advisors) that
    such Acquisition Proposal (A) would result in a transaction more favorable
    to the Company's stockholders than the transaction contemplated by this
    Agreement, (B) is made by a person financially capable of consummating such
    Acquisition Proposal,(C) provides for the acquisition by such person of all
    or substantially all of the assets of the Company and its Subsidiaries,
    taken as a whole, or at least a majority of the Shares outstanding on a
    fully diluted basis (any such Acquisition Proposal being referred to herein
    as a "Superior Proposal"); provided further that, at least three business
    days prior to the Board of
 
                                      A-26
<PAGE>
    Directors (or any committee thereof) withdrawing, modifying or changing its
    recommendation regarding the approval of the Merger or this Agreement in a
    manner adverse to Acquiror, or recommending to the stockholders of the
    Company any Acquisition Proposal, the Company shall send notice thereof to
    Acquiror (a "Superior Proposal Notice") and, concurrently therewith, shall
    pay the Break-Up Fee and the Documented Expenses to the Acquiror. The
    Superior Proposal Notice shall be deemed an irrevocable notice of
    termination of this Agreement by the Company pursuant to Section 8.1(d) and
    this Agreement shall be terminated in accordance therewith unless Acquiror
    takes such actions as are described in clauses (A) and (B) of Section
    8.1(d). For purposes hereof, "Acquisition Proposal" means any proposal for a
    merger, consolidation, tender or exchange offer or other business
    combination involving the Company or the acquisition of any substantial
    equity interest in, or a substantial portion of the assets of the Company
    and its Subsidiaries considered as a whole, other than the transactions
    contemplated by this Agreement. For purposes hereof, "New Bidder" means any
    person or entity other than those persons and entities to whom presentations
    by management of the Company concerning a possible sale of the Company were
    made between November 1, 1997 and the date of this Agreement. Without
    limiting the foregoing, it is understood and agreed that any violation of
    the restrictions set forth in this paragraph (i) by any officer, director,
    employee, affiliate, representative or agent (including attorneys,
    investment bankers and accountants) of the Company or any of its
    Subsidiaries shall be deemed to be a breach of this paragraph (i) by the
    Company.
 
        (ii) Concurrently with sending a Superior Proposal Notice in accordance
    with Section 4.1(a)(i), or upon any termination by Acquiror of this
    Agreement pursuant to Sections 8.1(e) or (f), the Company shall reimburse
    Acquiror for its expenses (including attorney's fees) actually and
    reasonably incurred by Acquiror in connection with the transactions
    contemplated by this Agreement, documented to the reasonable satisfaction of
    the Company, up to a maximum of $5,000,000 (the "Documented Expenses") and
    (y) pay to Acquiror $16,500,000 (the "Break-Up Fee"), in each case by wire
    transfer of immediately available funds to an account designated by Acquiror
    for such purpose.

    Material Adverse Effect on the Company;

    sharing, compensation, severance, termination, stock option, pension,
    retirement, deferred compensation, or other employee benefit plan,

    health benefit or other fringe benefit of any director, officer or employee
    (except for normal increases in the ordinary course of business that are

    SECTION 4.2 COVENANTS OF ACQUIROR; EMPLOYEE BENEFITS; INDEMNIFICATION.
 
    (a) Employee Benefits. As of the Effective Time, the employees of the
Company and each Subsidiary (the "Company Employees") shall continue employment
with the Surviving Corporation and its subsidiaries, respectively, in the same
positions and at the same level of wages and/or salary and employee benefits, as
in effect on the date hereof, with such changes as may occur before the
Effective Time in the ordinary course of business consistent with past practice.
Except as may be specifically required by applicable law or any agreement by
which the Company is bound, the Surviving Corporation and its subsidiaries shall
have the same right to terminate or change the conditions of any Company
Employee's employment or to amend, modify or terminate any employee benefit plan
program or policy, as the Company and its Subsidiaries have on the date hereof.
 
    (b) Notwithstanding any provisions of any Company or Subsidiary employee
benefit plan, program or policy (including any employee pension benefit plan
within the meaning of Section 3(2) of ERISA) to the contrary, at the Effective
Time any right of any employee to make future investments in shares of the
Company or to receive employer contributions in shares of the Company shall
terminate, and any shares of the Company held under any such plan, program or
policy shall be treated in the Merger in accordance with this Agreement, and any
Merger Consideration (including shares of Senior Preferred Stock) received
thereunder shall be, to the extent applicable, reinvested in accordance with the
terms of such plan, program or policy. Before the Effective Time, the Company
and the Subsidiaries shall take any and all action reasonably required to assure
that the right of any employee to make future investments in shares of the
Company and the obligation of the Company or any Subsidiary to contribute shares
of the Company under any such plan, program or policy is terminated as of the
Effective Time.
 
    (c) Indemnification; Directors' and Officers' Insurance. Subsequent to the
Effective Time as contemplated by Section 1.4 hereof, the Surviving Corporation
shall not, until the later of (i) the six-year anniversary date of the Effective
Date or (ii) the permitted termination or expiration date of any existing
Company or Subsidiary indemnification agreement or arrangement disclosed on
Schedule 4.2 (the period between the Effective Date and the later of such
subsequent dates, the "Indemnification Period"), amend the Certificate of
Incorporation or Bylaws of the Surviving Corporation or take any other action,
or fail to
 
                                      A-30
<PAGE>
take any action, the effect of which amendment, action or failure to act would
be to reduce or limit the rights to indemnity or advancement of expenses
afforded to those persons who served as directors or officers of the Company or
any present or past subsidiary at any time prior to the Effective Time or to
hinder, delay or make more difficult in any way the exercise of such rights to
indemnity or advancement of expenses or the ability of the Surviving Corporation
or any Subsidiary to indemnify such persons or advance expenses. The Surviving
Corporation shall at all times promptly exercise the powers granted to it by its
Certificate of Incorporation, its Bylaws and by applicable law to indemnify (and
to advance expenses to), subject to the terms and conditions thereof, to the
fullest extent possible those persons who served as directors or officers of the
Company and present or past subsidiaries prior to the Effective Time against all
claims and expenses made against or incurred by them arising from their service
in such capacities. Should any such person be made a party or be threatened to
be made a party to any threatened, pending or completed action, suit or
proceeding at any time during the Indemnification Period, by reason of the fact
that he was a director or officer of the Company or any present or past
subsidiary or was serving as an officer or director of any other enterprise at
the request of the Company, the provisions of this Section 4.2(c) shall continue
in effect until the final disposition of all such actions, suits or proceedings,
whether or not the Indemnification Period shall have expired. The provisions of
this Section 4.2(c) are intended to be for the benefit of, and shall be
enforceable by, each person entitled to indemnification hereunder, his heirs and
his personal representatives. In the event the Surviving Corporation or the
Acquiror or any of their respective successors or assigns (A) consolidates with
or merges into any other person and the Surviving Corporation shall not be the
continuing or surviving corporation or entity of such consolidation or merger or
(B) transfers all or substantially all of its properties and assets to any
person, the Surviving Corporation shall ensure that proper provision shall be
made so that the successors and assigns of the Surviving Corporation shall
assume the obligations set forth in this Section 4.2(c). The Surviving
Corporation shall obtain and maintain in effect for not less than six years
after the Effective Date, the current directors' and officers' liability
insurance policies maintained by the Company (provided that the Surviving
Corporation may substitute therefor a policy or policies providing substantially
equivalent coverage containing similar terms and conditions so long as no lapse
in coverage occurs as a result of such substitution) with respect to all
matters, including the transactions contemplated hereby, occurring prior to, and
including the Effective Date; provided that in no event shall the Surviving
Corporation be required to expend more than 200% of the current annual premiums
paid by the Company for such coverage (the Maximum Premium); and provided,
further, that if the Surviving Corporation is unable to obtain the amount of
insurance required by this Section 4.2(c) for such aggregate premium, the
Surviving Corporation shall obtain, if available, as much insurance as can be
obtained for an annual premium not in excess of the Maximum Premium.
 
    (d) Financing. Acquiror shall use commercially reasonable efforts, subject
to normal conditions, to arrange, as promptly as practicable, and consummate the
Financing (as defined in Section 5.9) pursuant to the commitment letters
referred to in Section 3.4 hereof (or involving such other financing as may be
acceptable to Acquiror in its sole discretion) in respect of the transactions
contemplated by this Agreement on customary commercial terms, including, subject
to normal conditions, using commercially reasonable efforts to assist the
Company in the negotiation of definitive agreements with respect thereto and to
satisfy all conditions applicable to Acquiror in such definitive agreements.
Subject to the Company having received the proceeds of the Financing, Acquiror
at Closing shall be capitalized with an equity contribution sufficient to
finance the transaction, in an amount up to $98,600,000. Acquiror will be under
no obligation pursuant to the immediately preceding sentence unless and until
the Company receives the proceeds of the Financing on terms consistent with the
commitment letters referenced in Section 3.4, or such other financings as may be
acceptable to Acquiror in its sole discretion. Acquiror shall use commercially
reasonable efforts to obtain a solvency opinion in connection with the
Financing, addressed to the Board of Directors of the Company.

    SECTION 4.3 CONDUCT OF BUSINESS BY ACQUIROR PENDING THE MERGER.  Prior to
the Effective Time, except as otherwise contemplated or permitted by this
Agreement: Acquiror shall not, and shall cause its subsidiaries not to take, or
agree to take, any actions that would make any representation or warranty of
Acquiror or its subsidiaries contained in this Agreement untrue or incorrect so
as to cause any of the conditions set forth in Article V hereof not to be
fulfilled as of the Effective Time. Notwithstanding the foregoing, this Section
4.3 shall not create any obligation on the part of Acquiror (or its affiliates)
with respect to the Financing, Acquiror's obligations with respect to the
Financing are set forth in Section 4.2(d) hereof.
 
    SECTION 4.4 COVENANTS OF ACQUIROR AND THE COMPANY.
 
    (a) Confidentiality. Prior to the Effective Time and after any termination
of this Agreement, each party to this Agreement shall hold (and not use, in the
conduct of its or their business or otherwise) and shall use all commercially
reasonable efforts to cause its officers, directors, employees, accountants,
counsel, consultants, advisors and agents (collectively, "Representatives") to
hold in confidence (and not use, in the conduct of its or their business or
otherwise), unless compelled to disclose by judicial or administrative process
or by other requirements of law, all documents and information concerning the
other parties furnished in connection with the transactions contemplated by this
Agreement, whether furnished before or after the date of this Agreement and
regardless of the manner in which it is furnished ("Confidential Information"),
together with all analyses, compilations, studies or other documents or records
prepared by a party hereto or any of its Representatives to the extent that such
analyses, compilations, studies or other documents or records contain or
otherwise reflect or are generated from Confidential Information ("Evaluation
Material"). Confidential Information shall not include information that can be
shown to have been (i) previously known on a nonconfidential basis by such
party, (ii) in the public domain through no fault of such party or (iii) later
lawfully acquired by such party from sources other than the other party.
Notwithstanding the foregoing, any party may disclose Confidential Information
and Evaluation Material to its Representatives in connection with evaluating the
transactions contemplated by this Agreement and to its lenders in connection
with obtaining the financing for the transactions contemplated by this Agreement
so long as such persons are informed by such party of the confidential nature of
such information and are directed by such party to treat such information

without limitation directors, officers and employees of the Acquiror and its
affiliates and counsel, accountants and other professionals retained by

Merger and the transactions contemplated hereby and to respond as promptly as
practicable to any inquiries received from the Federal Trade Commission (the
"FTC") or the Antitrust Division of the Department of justice (the "Antitrust
Division") for additional information or documentation and to respond as
promptly as practicable to all inquiries and

requests received from any State Attorney General or any other Governmental
Entity, in connection with antitrust matters. The Company and Acquiror shall use
commercially reasonable efforts to overcome any objections which may be raised
by the FTC or Antitrust Division. Acquiror shall reimburse the Company for all

connection with matters referred to in the immediately preceding sentence. The
Company shall make, subject to the condition that the transactions contemplated
herein actually occur, any undertakings (including undertakings to make

need not themselves be effective or made until after the transactions
contemplated hereby actually occur) required in order to comply with the
antitrust requirements or laws of any governmental entity, including the HSR
Act, in connection with the transactions contemplated by this Agreement,
provided that no such divestiture or undertaking shall be made unless reasonably
acceptable to Acquiror.
 
    (d) Best Efforts. Acquiror and the Company shall each use its best efforts
to perform its obligations under this Agreement to satisfy the conditions set
forth in Articles V and VI, and to consummate the Merger on the terms and
conditions set forth in this Agreement; provided, however, that this Section
4.4(d) shall not create any obligation to use best efforts with respect to those
obligations which are expressly conditioned upon the use of "reasonable" or
"commercially reasonable" efforts of similar terms.
 
    (e) Certain Filings. The Company and Acquiror shall use their best efforts
to cooperate with one another in determining whether any action by or in respect
of, or filing with, any governmental body, agency or official, or authority is
required (other than pursuant to the HSR Act), or any actions, consents,
approvals or waivers are required to be obtained from parties to any material
contracts, in connection with the consummation of the transactions contemplated
by this Agreement and in seeking to timely obtain any such actions, consents,
approvals or waivers, or making any such filings or furnishing information
required in connection therewith.
 
    (f) Public Announcements. Acquiror, and the Company shall consult with each
other before issuing any press release or making any public statement with
respect to this Agreement or the transactions contemplated hereby and, shall not
issue any such press release or make any such public statement without the prior
consent of the other party, which consent shall not be unreasonably withheld or
delayed; provided, however, that a party may, without the prior consent of the
other party, issue such press release or make such public statement as may upon
the advice of counsel be required by law, any securities exchange or the
National Association of Securities Dealers, Inc. if it has used all commercially
reasonable efforts to consult with the other party.
 
    (g) Form S-4; Proxy Statement; Schedule 13E-3; Shareholder Approval.

    Form S-4 (the "Form S-4") in which will be included a preliminary proxy
    statement for stockholders of the Company in connection with the
    solicitation of proxies to approve the transactions contemplated by this
    Agreement (such proxy statement together with any amendments thereof or
    supplements thereto, in each case, in the form or forms mailed to the
    Company's stockholders, being the "Proxy Statement"). Concurrently with the
    filing of the Proxy Statement, Acquiror and its respective affiliates (to
    the extent required by law) shall prepare and file with the SEC, together
    with the Company, a Rule 13E-3 Transaction Statement on Schedule 13E-3
    (together with all supplements and amendments thereto, the "Schedule 13E-3")
    with respect to the transactions contemplated by this Agreement. All filing
    fees required to be paid, and all printing, mailing and other costs of
    dissemination with respect to the Form S-4, Proxy Statement or Schedule
    13E-3 shall be paid by the Company. The Acquiror shall furnish all
    information concerning them and the holders of its capital stock as the
    Company may reasonably request in connection with such actions. The Company
    shall use its commercially reasonable efforts to have the Form S-4 declared
    effective under the Securities Act as promptly as practicable after such
    filing. The Company shall use its commercially reasonable efforts to cause
    the Proxy Statement to be mailed to the
 
                                      A-33
<PAGE>
    Company's stockholders as promptly as practicable after the Form S-4 is
    declared effective under the Securities Act. The Company shall use its
    commercially reasonable efforts to take all steps necessary to cause the
    Schedule 13E-3 to be filed with the SEC and to be disseminated to the
    holders of Shares, in each case, as and to the extent required by applicable
    federal securities laws. The Company shall take any action required to be
    taken under any applicable state securities laws in connection with the
    registration and qualification of the Shares of the Capital Stock to be
    issued in connection with the Merger.
 
        (ii) If at any time prior to the Special Meeting any event or
    circumstance relating to the Company, the Acquiror or any of their
    respective affiliates, or its or their respective officers or directors,
    should be discovered by the Company or the Acquiror that should be set forth
    in a supplement or amendment to the Proxy Statement or the Form S-4 or
    Schedule 13E-3, such party shall promptly inform the other party and the
    Company shall promptly supplement, amend, update, or correct the Form S-4,
    Proxy Statement and/or Schedule 13E-3 and shall cause such supplement,
    amendment, update or correction to be filed with the SEC and to be
    disseminated to the holders of Shares, in each case, as and to the extent
    required by applicable federal securities laws.
 
   
       (iii) The Company shall immediately notify the Acquiror of (A) the
    receipt of any comments from the SEC relating to the Form S-4, the Schedule
    13E-3 or the Proxy Statement, (B) any request by the SEC for any amendment
    or supplement to the Form S-4, the Schedule 13E-3 or Proxy Statement or for
    additional information, and (C) the effectiveness of the Form S-4, the
    Schedule 13E-3 and the clearance of the Proxy Statement, and the Schedule
    13E-3. The Company shall consult with the Acquiror with respect to, and
    prior to, all filings with the SEC, including the Form S-4 and Schedule
    13E-3 and any amendment or supplement thereto, and all mailings to the
    Companies' stockholders in connection with the Merger, including the Proxy
    Statement. No filing of the Form S-4, the Proxy Statement, the Schedule
    13E-3 or any amendment or supplement thereto shall be made by the Company
    without the consent of the Acquiror (not to be unreasonably withheld).
    
 
        (iv) The Company shall, as requested by Acquiror, take such action as
    may be necessary with applicable law and its Certificate of Incorporation
    and Bylaws, to convene a special meeting of the holders of the Shares
    ("Special Meeting") as promptly as practicable for the purpose of
    considering and taking action upon this Agreement. The Proxy Statement shall
    contain the recommendations of the Special Committee and the Board of
    Directors of the Company that; the Merger, this Agreement and the
    transactions contemplated hereby are fair to and in the best interests of
    the holders of Common Shares, (ii) the Merger, this Agreement and the
    transactions contemplated hereby are fair to and in the best interests of
    the holders of Preferred Shares, and (iii) the recommendation referred to in
    Section 2.20 hereof that holders of Common Shares and holders of Preferred
    Shares each approve the Merger, this Agreement and the transactions
    contemplated hereby. The Company will cause its transfer agent to make stock
    transfer records relating to the Company available to the Acquiror.
 
    (h) To the extent requested by Acquiror, each of the parties shall cooperate
with each other in taking, or causing to be taken, all actions necessary to
delist the Shares from the AMEX; provided that such delisting shall not be
effective until after the Effective Time. The parties also acknowledge that it
is Acquiror's present intention that, following the Merger, none of the shares
of the Company's capital stock will be listed on the AMEX or any other national
securities exchange and will not be quoted on the NASDAQ. Notwithstanding that
the Surviving Corporation may not be required to remain subject to the reporting
requirements of Section 13 or 15(d) of the Exchange Act, for the two (2) years
following the Effective Time, the Surviving Corporation shall file with the SEC
such reports as are specified in Section 13 and 15(d) of the Exchange Act and
required to be filed in respect of securities similar to the Senior Preferred
Shares by issuers subject to the reporting requirements of Section 13 of the
Exchange Act, such reports to be so filed at the times specified for the filings
of such reports required under such Sections;
 
                                      A-34
<PAGE>
provided that the Surviving Corporation shall have no obligation to file such
reports if fewer than 500,000 Senior Preferred Shares remain outstanding.
 
    SECTION 4.5 TRANSACTION LITIGATION.  The Company shall give Acquiror the
opportunity to participate in the defense or settlement of any litigation
against the Company and its directors directly relating to any of the
transactions contemplated by this Agreement until the Effective Time provided,
however, that no such settlement shall be agreed to without Acquiror's consent,
which consent shall not be unreasonably delayed or withheld; and provided
further that no settlement requiring a payment by a director shall be agreed to
without such director's consent.

shall have become impossible to satisfy;
 
    (c) by either the Acquiror or the Company, if the Merger has not been
consummated on or before August 31, 1998 (unless the failure to consummate the

this Agreement) provided that the right to terminate this Agreement pursuant to
this Section 8.1(c) solely because of the failure to be satisfied of Section 5.8

or the Stockholder Agreement shall have breached their material obligations
thereunder to Acquiror, or (C) or there shall have been a Change in Control of
the Company.

        (i) any person or group (other than Acquiror) acquires or beneficially
    owns, or enters into an agreement with the Company or any of its
    Subsidiaries to acquire, directly or indirectly, 25% or more of the

    of the assets, revenues or earning power of the Company and its
    Subsidiaries, taken as a whole (it being understood that (x) shares of
    Subsidiaries constitute assets of the Company for purposes hereof and (y)
    the beneficial ownership by the Rotko Entities of any Share beneficially
    owned by them as of the date of this Merger Agreement shall not constitute a
    "Change in Control"); or
 
        (ii) the Company distributes or transfers, or publicly announces its
    intention to distribute or transfer, to its shareholders, by dividend or
    otherwise, assets constituting 25% or more of the market value or earning

    The Company agrees to notify Acquiror within five business days of the
occurrence of any Change in Control.

    (f) by the Acquiror if (i) the Company is in breach at any time prior to the
Effective Time of any of the representations and warranties made by the Company
as though made on and as of such date, unless the inaccuracies (without giving

materiality exceptions contained therein) in such representations and
warranties, individually or in the aggregate, have not had and would not

documents delivered pursuant hereto, contains the entire understanding of the

amended by the parties hereto by action taken by or on behalf of their
respective Boards of Directors at any time prior to the Effective Time;

    (b) No provision of the Confidentiality Agreement shall limit Acquiror's
right to exercise the Options granted to it under the Option Agreement or to

January 14, 1998
The Board of Directors
MEDIQ Incorporated

Pennsauken, New Jersey 08110
 
Members of the Board:
 
You have requested our opinion as to the fairness, from a financial point of
view, to the stockholders of MEDIQ Incorporated ("MEDIQ"), other than Rollover
Holders (as defined below), of the consideration to be received by such holders
pursuant to the terms and subject to the conditions set forth in the Agreement
and Plan of Merger, dated as of January 14, 1998 (the "Merger Agreement"), by
and among MQ Acquisition Corporation ("MQ") and MEDIQ. As more fully described
in the Merger Agreement, (i) MQ will be merged with and into MEDIQ (the
"Merger") and (ii) each outstanding share of the common stock, par value $1.00
per share, of MEDIQ (the "MEDIQ Common Stock") and each outstanding share of
Series A preferred stock, par value $0.50 per share, of MEDIQ (the "MEDIQ
Preferred Stock" and, together with the MEDIQ Common Stock, the "Shares") will
be converted into the right to receive (i) $13.75 in cash (the "Cash Amount")
and (ii) 0.075 of a share of newly issued Series A 13.0% cumulative compounding
preferred stock, par value $0.01 per share, of MEDIQ, with a liquidation
preference of $10.00 per share (the "Senior Preferred Stock" and, together with
the Cash Amount, the "Merger Consideration"). We have been advised by
representatives of MEDIQ that members of the Rotko family, related trusts and
certain members of the management of MEDIQ will, in connection with the
transactions contemplated by the Merger, rollover a portion of their Shares or
options to purchase such Shares, as the case may be, into newly issued
securities of MEDIQ (such stockholders and option holders, the "Rollover
Holders").
 
In arriving at our opinion, we reviewed the Merger Agreement and the terms of
the Senior Preferred Stock attached as an exhibit thereto and held discussions
with certain senior officers, directors and other representatives and advisors
of MEDIQ and certain senior officers and other representatives and advisors of
MQ concerning the business, operations and prospects of MEDIQ. We examined
certain publicly available business and financial information relating to MEDIQ
as well as certain financial forecasts and other information and data for MEDIQ
which were provided to or otherwise discussed with us by the management of
MEDIQ. We reviewed the financial terms of the Merger as set forth in the Merger
Agreement in relation to, among other things: current and historical market
prices and trading volumes of the Shares; the financial condition and historical
and projected earnings and other operating data of MEDIQ; and the capitalization
of MEDIQ and MQ. We considered, to the extent publicly available, the financial
terms of other 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 MEDIQ. In
connection with our engagement, we were requested to approach, and we held
discussions with, third parties to solicit indications of interest in the
possible acquisition of MEDIQ. In addition to the foregoing, we conducted such
other analyses and examinations and considered such other financial, economic
and market criteria as we deemed appropriate in arriving at our opinion.
 
In rendering our opinion, we have assumed and relied, without independent
verification, upon the accuracy and completeness of all financial and other
information and data publicly available or furnished to or otherwise reviewed by
or discussed with us. With respect to financial forecasts and other information
 
                                      B-1

and data provided to or otherwise reviewed by or discussed with us, we have been
advised by the management of MEDIQ that such forecasts and other information and
data were reasonably prepared reflecting the best currently available estimates
and judgments of the management of MEDIQ as to the future financial performance
of MEDIQ. We also have been advised by representatives of MEDIQ that, in the
Merger, the MEDIQ Preferred Stock will be treated as the equivalent of the MEDIQ
Common Stock into which it is convertible and therefore, with your consent, have
evaluated the MEDIQ Preferred Stock as the equivalent of the MEDIQ Common Stock
for purposes of our opinion. We have assumed, with your consent, that the Merger
will be recorded as a recapitalization for financial reporting purposes. We
express no opinion as to what the value of the Senior Preferred Stock will be
when issued pursuant to the Merger or the price at which the Senior Preferred
Stock will trade or otherwise be transferable subsequent to the Merger. We have
not made or been provided with an independent evaluation or appraisal of the
assets or liabilities (contingent or otherwise) of MEDIQ nor have we made any
physical inspection of the properties or assets of MEDIQ. Our opinion is
necessarily based upon information available to us, and financial, stock market
and other conditions and circumstances existing and disclosed to us, as of the
date hereof.
 
Smith Barney Inc. (now associated with Salomon Brothers Inc and collectively
with Salomon Brothers Inc doing business as Salomon Smith Barney) has been
engaged to render financial advisory services to MEDIQ in connection with the
Merger and will receive a fee for such services, a significant portion of which
is contingent upon consummation of the Merger. We also will receive a fee upon
the delivery of this opinion. In the ordinary course of our business, we and our
affiliates may actively trade or hold the securities of MEDIQ for our own
account or for the account of our customers and, accordingly, may at any time
hold a long or short position in such securities. In addition, we and our
affiliates (including Travelers Group Inc. and its affiliates) may maintain
relationships with MEDIQ and affiliates of MQ.
 
Our advisory services and the opinion expressed herein are provided for the
information of the Board of Directors of MEDIQ in its evaluation of the proposed
Merger, and our opinion is not intended to be and does not constitute a
recommendation to any stockholder as to how such stockholder should vote on the
proposed Merger. Our opinion may not be published or otherwise used or referred
to, nor shall any public reference to Salomon Smith Barney be made, without our
prior written consent.
 
Based upon and subject to the foregoing, our experience as investment bankers,
our work as described above and other factors we deemed relevant, we are of the
opinion that, as of the date hereof, the Merger Consideration to be received in
the Merger by holders of Shares (other than Rollover Holders) is fair, from a
financial point of view, to such holders.
 
Very truly yours,
/s/ SALOMON SMITH BARNEY

        (1) Provided, however, that no appraisal rights under this section shall
    be available for the shares of any class or series of stock, which stock, or

    meeting of stockholders to act upon the agreement of merger or
    consolidation, were either (i) listed on a national securities exchange or

    system by the National Association of Securities Dealers, Inc. or (ii) held
    of record by more than 2,000 holders; and further provided that no appraisal
    rights shall be available for any shares of stock of the constituent

    subsections (f) of sec. 251 of this title.
 
        (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
    under this section shall be available for the shares of any class or series
    of stock of a constituent corporation if the holders thereof are required by
    the terms of an agreement of merger or consolidation pursuant to sec. 251,
    252, 254, 257, 258, 263 and 264 of this title to accept for such stock

       described in the foregoing subparagraphs a., b. and c. of this paragraph.

        (3) In the event all of the stock of a subsidiary Delaware corporation
    party to a merger effected under sec. 253 of this title is not owned by the
    parent corporation immediately prior to the merger, appraisal rights shall
    be available for the shares of the subsidiary Delaware corporation.
 
   
    (c) Any corporation may provide in its Certificate of Incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its Certificate of
Incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets of
the corporation. If the Certificate of Incorporation contains such a provision,
the procedures of this section, including those set forth in subsections (d) and
(e) of this section, shall apply as nearly as is practicable.
    
 
    (d) Appraisal rights shall be perfected as follows:
 
        (1) If a proposed merger or consolidation for which appraisal rights are
    provided under this section is to be submitted for approval at a meeting of
    stockholders, the corporation, not less than 20 days prior to the meeting,
    shall notify each of its stockholders who was such on the record date for
    such meeting with respect to shares for which appraisal rights are available
    pursuant to subsections (b) or (c) hereof that appraisal rights are
    available for any or all of the shares of the constituent corporations, and
    shall include in such notice a copy of this section. Each stockholder
    electing to demand the appraisal of his shares shall deliver to the
    corporation, before the taking of the vote on the merger or consolidation, a
    written demand for appraisal of his shares. Such demand will be sufficient
    if it reasonably informs the corporation of the identity of the stockholder
    and that the stockholder intends thereby to demand the appraisal of his
    shares. A proxy or vote against the merger or consolidation shall not
    constitute such a demand. A stockholder electing to take such action must do
    so by a separate written demand as herein provided. Within 10 days after the
    effective date of such merger or consolidation, the surviving or resulting
    corporation shall notify each stockholder of each constituent corporation
    who has complied with this subsection and has not voted in favor of or
    consented to the merger or consolidation of the date that the merger or
    consolidation has become effective; or
 
        (2) If the merger or consolidation was approved pursuant to Section228
    or Section253 of this title, each constituent corporation, either before the
    effective date of the merger or consolidation or within ten days thereafter,
    shall notify each of the holders of any class or series of stock of such
    constituent corporation who are entitled to appraisal rights of the approval
    of the merger or consolidation and that appraisal rights are available for
    any or all shares of such class or series of stock of such constituent
    corporation, and shall include in such notice a copy of this section;
    provided that, if the notice is given on or after the effective date of the
    merger or consolidation, such notice shall be given by the surviving or
    resulting corporation to all such holders of any class or series of stock of
    a constituent corporation that are entitled to appraisal rights. Such notice
    may, and, if given on or after the effective date of the merger or
    consolidation, shall, also notify such stockholders of the effective date of
    the merger or consolidation. Any stockholder entitled to appraisal rights
    may, within 20 days after the date of mailing of such notice, demand in
    writing from the surviving or resulting corporation the appraisal of such
    holder's shares. Such demand will be sufficient if it reasonably informs the
    corporation of the identity of the stockholder and that the stockholder
    intends thereby to demand the appraisal of such holder's shares. If such
    notice did not notify stockholders of the effective date of the merger or
    consolidation, either (i) each such constituent corporation shall send a
    second notice before the effective date of the merger or consolidation
    notifying each of the holders of any class or series of stock of such
    constituent corporation that are entitled to appraisal rights of the
    effective date of the merger or consolidation or (ii) the surviving or
    resulting corporation shall send such a second notice to all such holders on
    or within 10 days after such effective date; provided, however, that is such
    second notice is sent more than 20 days following the sending of the first
    notice, such second notice need only be sent to each stockholder who is
    entitled to appraisal rights and who has demanded appraisal of such holder's
    shares in accordance with this subsection. An affidavit of the secretary or
 
                                      C-2
<PAGE>
    assistant secretary or of the transfer agent of the corporation that is
    required to give either notice that such notice has been given shall, in the
    absence of fraud, be prima facie evidence of the facts stated therein. For
    purposes of determining the stockholders entitled to receive either notice,
    each constituent corporation may fix, in advance, a record date that shall
    be not more than 10 days prior to the date the notice is given, provided,
    that if the notice is given on or after the effective date of the merger or
    consolidation, the record date shall be such effective date. If no record
    date is fixed and the notice is given prior to the effective date, the
    record date shall be the close of business on the day next preceding the day
    on which the notice is given.
 
    (e) Within 120 days after the effective date of the merger or consolidation,
the surviving or resulting corporation or any stockholder who has complied with
subsections (a) and (d) hereof and who is otherwise entitled to appraisal
rights, may file a petition in the Court of Chancery demanding a determination
of the value of the stock of all such stockholders. Notwithstanding the
foregoing, at any time within 60 days after the effective date of the merger or
consolidation, any stockholder shall have the right to withdraw his demand for
appraisal and to accept the terms offered upon the merger or consolidation.
Within 120 days after the effective date of the merger or consolidation, any
stockholder who has complied with the requirements of subsections (a) and (d)
hereof, upon written request, shall be entitled to receive from the corporation
surviving the merger or resulting from the consolidation a statement setting
forth the aggregate number of shares not voted in favor of the merger or
consolidation and with respect to which demands for appraisal have been received
and the aggregate number of holders of such shares. Such written statement shall
be mailed to the stockholder within 10 days after his written request for such a
statement is received by the surviving or resulting corporation or within 10
days after expiration of the period for delivery of demands for appraisal under
subsection (d) hereof, whichever is later.
 
    (f) Upon the filing of any such petition by a stockholder, service of a copy
thereof shall be made upon the surviving or resulting corporation, which shall
within 20 days after such service file in the office of the Register in Chancery
in which the petition was filed a duly verified list containing the names and
addresses of all stockholders who have demanded payment for their shares and
with whom agreements as to the value of their shares have not been reached by
the surviving or resulting corporation. If the petition shall be filed by the
surviving or resulting corporation, the petition shall be accompanied by such a
duly verified list. The Register in Chancery, if so ordered by the Court, shall
give notice of the time and place fixed for the hearing of such petition by
registered or certified mail to the surviving or resulting corporation and to
the stockholders shown on the list at the addresses therein stated. Such notice
shall also be given by 1 or more publications at least 1 week before the day of
the hearing, in a newspaper of general circulation published in the City of
Wilmington, Delaware or such publication as the Court deems advisable. The forms
of the notices by mail and by publication shall be approved by the Court, and
the costs thereof shall be borne by the surviving or resulting corporation.
 
    (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled to
appraisal rights. The Court may require the stockholders who have demanded an
appraisal for their shares and who hold stock represented by certificates to
submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as to
such stockholder.
 
    (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any element
of value arising from the accomplishment or expectation of the merger or
consolidation, together with a fair rate of interest, if any, to be paid upon
the amount determined to be the fair value. In determining such fair value, the
Court shall take into account all relevant factors. In determining the fair rate
of interest, the Court may consider all relevant factors, including the rate of
interest which the surviving or resulting corporation would have had to pay to
borrow money during the pendency of the proceeding. Upon application by the
surviving or resulting corporation or by any stockholder entitled to participate
in the appraisal proceeding, the Court may, in its discretion,
 
                                      C-3
<PAGE>
permit discovery or other pretrial proceedings and may proceed to trial upon the
appraisal prior to the final determination of the stockholder entitled to an
appraisal. Any stockholder whose name appears on the list filed by the surviving
or resulting corporation pursuant to subsection (f) of this section and who has
submitted his certificates of stock to the Register in Chancery, if such is
required, may participate fully in all proceedings until it is finally
determined that he is not entitled to appraisal rights under this section.
 
    (i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to the
stockholders entitled thereto. Interest may be simple or compound, as the Court
may direct. Payment shall be so made to each such stockholder, in the case of
holders of uncertificated stock forthwith, and the case of holders of shares
represented by certificates upon the surrender to the corporation of the
certificates representing such stock. The Court's decree may be enforced as
other decrees in the Court of Chancery may be enforced, whether such surviving
or resulting corporation be a corporation of this State or of any state.
 
    (j) The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.
 
    (k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded his appraisal rights as provided in subsection (d)
of this section shall be entitled to vote such stock for any purpose or to
receive payment of dividends or other distributions on the stock (except
dividends or other distributions payable to stockholders of record at a date
which is prior to the effective date of the merger or consolidation); provided,
however, that if no petition for an appraisal shall be filed within the time
provided in subsection (e) of this section, or if such stockholder shall deliver
to the surviving or resulting corporation a written withdrawal of his demand for
an appraisal and an acceptance of the merger or consolidation, either within 60
days after the effective date of the merger or consolidation as provided in
subsection (e) of this section or thereafter with the written approval of the
corporation, then the right of such stockholder to an appraisal shall cease.
Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery
shall be dismissed as to any stockholder without the approval of the Court, and
such approval may be conditioned upon such terms as the Court deems just.
 
    (l) The shares of the surviving or resulting corporation to which the shares
of such objecting stockholders would have been converted had they assented to
the merger or consolidation shall have the status of authorized and unissued
shares of the surviving or resulting corporation.

        or more series, each such series to have the terms stated herein and in
        the resolution of the Board of Directors of the Corporation providing
        for its issue. All shares of any one series of Preferred Stock will be
        identical, but shares of different series of Preferred Stock need not be
        identical or rank equally except insofar as provided by law or herein.
 
     b. CREATION OF SERIES. The Board of Directors will have authority by
        resolution to cause to be created one or more series of Preferred Stock,
        and to determine and fix with respect to each series prior to the
        issuance of any shares of the series to which such resolution relates:
 
        (i) The distinctive designation of the series and the number of shares
            which will constitute the series, which number may be increased or
            decreased (but not below the number of shares then outstanding) from
            time to time by action of the Board of Directors;
 
        (ii) The dividend rate and the times of payment of dividends on the
             shares of the series, whether dividends will be cumulative, and if
             so, from what date or dates;
 
       (iii) The price or prices at which, and the terms and conditions on
             which, the shares of the series may be redeemed at the option of
             the Corporation;
 
        (iv) Whether or not the shares of the series will be entitled to the
             benefit of a retirement or sinking fund to be applied to the
             purchase or redemption of such shares and, if so entitled, the
             amount of such fund and the terms and provisions relative to the
             operation thereof;
 
        (v) Whether or not the shares of the series will be convertible into, or
            exchangeable for, any other shares of stock of the Corporation or
            other securities, and if so convertible or exchangeable, the
            conversion price or prices, or the rates of exchange, and any
            adjustments thereof, at which such conversion or exchange may be
            made, and any other terms and conditions of such conversion or
            exchange;
 
                                      D-1
<PAGE>
        (vi) The rights of the shares of the series in the event of voluntary or
             involuntary liquidation, dissolution or winding up of the
             Corporation;
 
       (vii) Whether or not the shares of the series will have priority over or
             be on a parity with or be junior to the shares of any other series
             or class in any respect or will be entitled to the benefit of
             limitations restricting the issuance of shares of any other series
             or class having priority over or being on a parity with the shares
             of such series in any respect, or restricting the payment of
             dividends on or the making of other distributions in respect of
             shares of any other series or class ranking junior to the shares of
             the series as to dividends or assets, or restricting the purchase
             or redemption of the shares of any such junior series or class, and
             the terms of any such restriction;
 
      (viii) Whether the series will have voting rights, in addition to any
             voting rights provided by law, and, if so, the terms of such voting
             rights; and
 
        (ix) Any other preferences, qualifications, privileges, options and
             other relative or special rights and limitations of that series.
 
     c. DIVIDENDS. Holders of Preferred Stock shall be entitled to receive, when
        and as declared by the Board of Directors, out of funds legally
        available for the payment thereof, dividends at the rates fixed by the
        Board of Directors for the respective series, and no more, before any
        dividends shall be declared and paid, or set apart for payment, on
        Common Stock with respect to the same dividend period.
 
     d. PREFERENCE ON LIQUIDATION. In the event of the voluntary or involuntary
        liquidation, dissolution or winding up of the Corporation, holders of
        each series of Preferred Stock will be entitled to receive the amount
        fixed for such series plus, in the case of any series on which dividends
        will have been determined by the Board of Directors to be cumulative, an
        amount equal to all dividends accumulated and unpaid thereon to the date
        of final distribution whether or not earned or declared before any
        distribution shall be paid, or set aside for payment, to holders of
        Common Stock. If the assets of the Corporation are not sufficient to pay
        such amounts in full, holders of all shares of Preferred Stock will
        participate in the distribution of assets ratably in proportion to the
        full amounts to which they are entitled or in such order or priority, if
        any, as will have been fixed in the resolution or resolutions providing
        for the issue of the series of Preferred Stock. Neither the merger nor
        consolidation of the Corporation into or with any other corporation, nor
        a sale, transfer or lease of all or part of its assets, will be deemed a
        liquidation, dissolution or winding up of the corporation within the
        meaning of this paragraph except to the extent specifically provided for
        herein.
 
     e. REDEMPTION. The Corporation, at the option of the Board of Directors,
        may redeem all or part of the shares of any series of Preferred Stock on
        the terms and conditions fixed for such series.
 
     f. VOTING RIGHTS. Except as otherwise required by law, as otherwise
        provided herein or as otherwise determined by the Board of Directors as
        to the shares of any series of Preferred Stock prior to the issuance of
        any such shares, the holders of Preferred Stock shall have no voting
        rights and shall not be entitled to any notice of meeting of
        stockholders.
 
    5. BYLAWS. The board of directors of the Corporation is authorized to adopt,
amend or repeal the bylaws of the Corporation, except as otherwise specifically
provided therein.
 
    6. ELECTIONS OF DIRECTORS. Elections of directors need not be by written
ballot unless the bylaws of the Corporation shall so provide.
 
    7. RIGHT TO AMEND. The Corporation reserves the right to amend any provision
contained in this Certificate as the same may from time to time be in effect in
the manner now or hereafter prescribed by law, and all rights conferred on
stockholders or others hereunder are subject to such reservation.
 
                                      D-2
<PAGE>
    8. LIMITATION ON LIABILITY. The directors of the Corporation shall be
entitled to the benefits of all limitations on the liability of directors
generally that are now or hereafter become available under the General
Corporation Law of Delaware. Without limiting the generality of the foregoing,
no director of the Corporation shall be liable to the Corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director,
except for liability (i) for any breach of the director's duty of loyalty to the
Corporation or its stockholders, (ii) for acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (iii) under
Section 174 of the Delaware General Corporation Law, or (iv) for any transaction
from which the director derived an improper personal benefit. Any repeal or
modification of this Section 8 shall be prospective only, and shall not affect,
to the detriment of any director, any limitation on the personal liability of a
director of the Corporation existing at the time of such repeal or modification.

                                       OF
                               MEDIQ INCORPORATED
 
    MEDIQ Incorporated, a Delaware corporation (hereinafter called the
"Corporation"), pursuant to the provisions of Section 151 of the General
Corporation Law of the State of Delaware, does hereby make this Certificate of
Designation under the corporate seal of the Corporation and does hereby state
and certify that pursuant to the authority expressly vested in the Board of
Directors of the Corporation by the Certificate of Incorporation, the Board of
Directors has duly adopted the following resolutions:
 
    RESOLVED, that, pursuant to Article 4 of the Certificate of Incorporation
(which authorizes the creation and issuance of shares of Preferred Stock on such
terms as are determined by the Board of Directors), the Board of Directors
hereby fixes the designations and preferences and relative, participating,
optional and other special rights and qualifications, limitations and
restrictions of the following series of Preferred Stock:
 
    A. SERIES A PREFERRED STOCK.
 
        1. DESIGNATION OF SERIES. The designation of the series of Preferred
    Stock authorized by this resolution shall be "Series A 13.0% Cumulative
    Compounding Preferred Stock" ("Series A Preferred Stock") consisting of
    10,000,000 shares. The par value of Series A Preferred Stock shall be $.01
    per share.
 
        2. RANK. With respect to dividend rights and rights on liquidation,
    winding up and dissolution of the Corporation, Series A Preferred Stock
    shall rank (a) senior to the Common Stock of the Corporation, par value $.01
    per share ("COMMON STOCK"), the Series B Preferred Stock (defined in
    paragraph B below), the Series C Preferred Stock (defined in paragraph B
    below), and each other class of capital stock or class or series of
    preferred stock issued by the Corporation after the date hereof the terms of
    which specifically provide that such class or series shall rank junior to
    the Series A Preferred Stock as to dividend distributions or distributions
    upon the liquidation, winding up and dissolution of the Corporation
    (collectively referred to as "SERIES A JUNIOR SECURITIES"), (b) on a parity
    with each other class of capital stock or class or series of preferred stock
    issued by the Corporation after the date hereof the terms of which do not
    specifically provide that they rank junior to Series A Preferred Stock or
    senior to Series A Preferred Stock as to dividend distributions or
    distributions upon liquidation, winding up and dissolution of the
    Corporation (collectively referred to as "SERIES A PARITY SECURITIES"), and
    (c) junior to each other class of capital stock or other class or series of
    preferred stock issued by the Corporation that by its terms is senior to the
    Series A Preferred Stock with respect to dividend distributions or
    distributions upon the liquidation, winding up and dissolution of the
    Corporation (collectively referred to as "SERIES A SENIOR SECURITIES").
 
        3. DIVIDENDS.
 
           (a) Each Holder of Series A Preferred Stock shall be entitled to
       receive, when, as and if declared by the Board of Directors, out of funds
       legally available therefor, cash dividends on each share of Series A
       Preferred Stock at a rate equal to $1.30 per share per annum. All
       dividends shall be cumulative, whether or not earned or declared, and
       shall accrue on a daily basis from the date of issuance of Series A
       Preferred Stock, and shall be payable semi-annually in arrears on each
       Dividend Payment Date, commencing on the second Dividend Payment Date
       after the date of issuance of such Series A Preferred Stock. Each
       dividend on Series A Preferred Stock shall be payable to the Holders of
       record of Series A Preferred Stock as they appear on the stock register
       of the Corporation on such record date as may be fixed by the Board of
       Directors, which record
 
                                      D-4
<PAGE>
       date shall not be less than 10 nor more than 60 days prior to the
       applicable Dividend Payment Date. Dividends shall cease to accrue in
       respect of shares of Series A Preferred Stock on the date of their
       repurchase by the Corporation unless the Corporation shall have failed to
       pay the relevant repurchase price on the date fixed for repurchase.
       Notwithstanding anything to the contrary set forth above, unless and
       until such dividends are declared by the Board of Directors, there shall
       be no obligation to pay such dividends; PROVIDED, that such dividends
       shall continue to cumulate and shall be added to the Liquidation
       Preference (as provided in Paragraph A4(a) below) at the time of
       repurchase as provided herein if not earlier declared and paid. Accrued
       dividends on the Series A Preferred Stock if not paid on the first or any
       subsequent Dividend Payment Date following accrual shall thereafter
       accrue additional dividends ("ADDITIONAL DIVIDENDS") in respect thereof,
       compounded annually, at the rate of 13.0% per annum.
 
           (b) All dividends paid with respect to shares of Series A Preferred
       Stock pursuant to paragraph A(3)(a) shall be paid pro rata to the Holders
       entitled thereto.
 
           (c) Dividends on account of arrears for any past Dividend Period and
       dividends in connection with any optional redemption pursuant to
       paragraph A(5)(a) may be declared and paid at any time, without reference
       to any regular Dividend Payment Date, to the Holders of record on any
       date as may be fixed by the Board of Directors, which date is not more
       than 60 days prior to the payment of such dividends.
 
           (d) As long as any Series A Preferred Stock is outstanding, no
       dividends shall be declared by the Board of Directors or paid or funds
       set apart for the payment of dividends or other distributions on any
       Series A Parity Securities for any period, and no Series A Parity
       Securities may be repurchased, redeemed or otherwise acquired, nor may
       funds be set apart for such payment (other than dividends, other
       distributions, redemptions, repurchases or acquisitions payable in Series
       A Junior Securities and cash in lieu of fractional shares of such Series
       A Junior Securities in connection therewith), unless (i) full Accumulated
       Dividends have been paid or set apart for such payment on the Series A
       Preferred Stock and Series A Parity Securities for all Dividend Periods
       terminating on or prior to the date of payment of such dividends or

       Parity Securities (the "SERIES A PARITY PAYMENT DATE") and (ii) any such

       dividends declared and paid per share on outstanding Series A Preferred
       Stock and each other share of Series A Parity Securities will in all
       cases bear to each other the same ratio that accrued and unpaid dividends
       (including any Accumulated Dividends) per share of outstanding Series A
       Preferred Stock and such other outstanding shares of Series A Parity
       Securities bear to each other.
 
           (e) The Holders shall be entitled to receive the dividends provided
       for in paragraph A(3)(a) hereof in preference to and in priority over any
       dividends upon any of the Series A Junior Securities. Such dividends on
       the Series A Preferred Stock shall be cumulative, whether or not earned
       or declared, so that if at any time full Accumulated Dividends on all
       shares of Series A Preferred Stock then outstanding for all Dividend
       Periods then elapsed have not been paid or set aside for payment, the
       amount of such unpaid dividends shall be paid before any sum shall be set
       aside for or applied by the Corporation to the purchase, redemption or
       other acquisition for value of any shares of Series A Junior Securities
       (either pursuant to any applicable sinking fund requirement or otherwise)
       or any dividend or other distribution shall be paid or declared or set
       apart for payment on any Series A Junior Securities (the date of any such
       actions to be referred to as the "SERIES A JUNIOR PAYMENT DATE");
       PROVIDED, HOWEVER, that the foregoing shall not (i) prohibit the
       Corporation from repurchasing shares of Series A Junior Securities from a
       holder thereof who is, or was, a director or employee of the Corporation
       (or an affiliate of the Corporation) and (ii) prohibit the Corporation
       from making dividends, other distributions, redemptions, repurchases or
       acquisitions in respect of Series A Junior Securities payable in
 
                                      D-5
<PAGE>
       Series A Junior Securities and cash in lieu of fractional shares of such
       Series A Junior Securities in connection therewith.
 
           (f) Dividends payable on Series A Preferred Stock for any period less
       than one year shall be computed on the basis of a 360-day year consisting
       of twelve 30-day months and the actual number of days elapsed in the
       period for which such dividends are payable.
 
        4. LIQUIDATION PREFERENCE.
 
           (a) Upon any voluntary or involuntary liquidation, dissolution or
       winding up of the Corporation, the Holders of all shares of Series A

       unpaid thereon, including Additional Dividends, to the date of final
       distribution (the "LIQUIDATION PREFERENCE") and no more, before any
       distribution is made on any Series A Junior Securities. If upon any
       voluntary or involuntary liquidation, dissolution or winding up of the
       Corporation, the application of all amounts available for payments with
       respect to Series A Preferred Stock and all other Series A Parity
       Securities would not result in payment in full of Series A Preferred
       Stock and such other Series A Parity Securities, the Holders and holders
       of Series A Parity Securities shall share equally and ratably in any
       distribution of assets of the Corporation in proportion to the full
       liquidation preference to which each is entitled. After payment in full
       pursuant to this paragraph A(4)(a), the Holders shall not be entitled to
       any further participation in any distribution in the event of

       sale, conveyance, exchange or transfer (for cash, shares of stock,

       other business combination of the Corporation with one or more
       corporations (whether or not the Corporation is the surviving
       corporation) shall be deemed to be a voluntary or involuntary
       liquidation, dissolution or winding up of the Corporation.

        3. DIVIDENDS.
 
           (a) Each Holder of Series B Preferred Stock shall be entitled to
       receive, when, as and if declared by the Board of Directors, out of funds
       legally available therefor, cash dividends on each share of Series B
       Preferred Stock at a rate equal to $1.325 per share PER ANNUM. All
       dividends shall be cumulative, whether or not earned or declared, and
       shall accrue on a daily basis from the date of issuance of Series B
       Preferred Stock, and shall be payable semi-annually in arrears on
 
                                      D-11
<PAGE>
       each Dividend Payment Date, commencing on the second Dividend Payment
       Date after the date of issuance of such Series B Preferred Stock. Each
       dividend on Series B Preferred Stock shall be payable to the Holders of
       record of Series B Preferred Stock as they appear on the stock register
       of the Corporation on such record date as may be fixed by the Board of
       Directors, which record date shall not be less than 10 nor more than 60
       days prior to the applicable Dividend Payment Date. Dividends shall cease
       to accrue in respect of shares of Series B Preferred Stock on the date of
       their repurchase by the Corporation unless the Corporation shall have
       failed to pay the relevant repurchase price on the date fixed for
       repurchase. Notwithstanding anything to the contrary set forth above,
       unless and until such dividends are declared by the Board of Directors,
       there shall be no obligation to pay such dividends; PROVIDED, that such
       dividends shall continue to cumulate and shall be added to the
       Liquidation Preference (as provided in paragraph A4(a) below) at the time
       of repurchase as provided herein if not earlier declared and paid.
       Accrued dividends on the Series B Preferred Stock if not paid on the
       first or any subsequent Dividend Payment Date following accrual shall
       thereafter accrue additional dividends ("ADDITIONAL DIVIDENDS") in
       respect thereof, compounded annually, at the rate of 13.25% per annum.
 
           (b) All dividends paid with respect to shares of Series B Preferred
       Stock pursuant to paragraph A(3)(a) shall be paid PRO RATA to the Holders
       entitled thereto.
 
           (c) Dividends on account of arrears for any past Dividend Period may
       be declared and paid at any time, without reference to any regular
       Dividend Payment Date, to the Holders of record on any date as may be
       fixed by the Board of Directors, which date is not more than 60 days
       prior to the payment of such dividends.
 
           (d) As long as any Series B Preferred Stock is outstanding, no
       dividends shall be declared by the Board of Directors or paid or funds
       set apart for the payment of dividends or other distributions on any
       Series B Parity Securities for any period, and no Series B Parity
       Securities may be repurchased, redeemed or otherwise acquired, nor may
       funds be set apart for such payment (other than dividends, other
       distributions, redemptions, repurchases or acquisitions payable in Series
       B Junior Securities and cash in lieu of fractional shares of such Series
       B Junior Securities in connection therewith), unless (i) full Accumulated
       Dividends have been paid or set apart for such payment on the Series B
       Preferred Stock and Series B Parity Securities for all Dividend Periods
       terminating on or prior to the date of payment of such dividends or
       distributions on, or such repurchase or redemption of, such Series B
       Parity Securities (the "SERIES B PARITY PAYMENT DATE") and (ii) any such
       dividends are declared and paid pro rata so that the amounts of any
       dividends declared and paid per share on outstanding Series B Preferred
       Stock and each other share of Series B Parity Securities will in all
       cases bear to each other the same ratio that accrued and unpaid dividends
       (including any Accumulated Dividends) per share of outstanding Series B
       Preferred Stock and such other outstanding shares of Series B Parity
       Securities bear to each other.
 
           (e) The Holders shall be entitled to receive the dividends provided
       for in paragraph A(3)(a) hereof in preference to and in priority over any
       dividends upon any of the Series B Junior Securities. Such dividends on
       the Series B Preferred Stock shall be cumulative, whether or not earned
       or declared, so that if at any time full Accumulated Dividends on all
       shares of Series B Preferred Stock then outstanding for all Dividend
       Periods then elapsed have not been paid or set aside for payment, the
       amount of such unpaid dividends shall be paid before any sum shall be set
       aside for or applied by the Corporation to the purchase, redemption or
       other acquisition for value of any shares of Series B Junior Securities
       (either pursuant to any applicable sinking fund requirement or otherwise)
       or any dividend or other distribution shall be paid or declared or set
       apart for payment on any Series B Junior Securities (the date of any such
       actions to be referred to as the "SERIES B JUNIOR PAYMENT DATE");
       PROVIDED, HOWEVER, that the foregoing shall not (i) prohibit the
       Corporation from repurchasing shares of Series B Junior Securities from a
       holder thereof
 
                                      D-12
<PAGE>
       who is, or was, a director or employee of the Corporation (or an
       affiliate of the Corporation) and (ii) prohibit the Corporation from
       making dividends, other distributions, redemptions, repurchases or
       acquisitions in respect of Series B Junior Securities payable in Series B
       Junior Securities and cash in lieu of fractional shares of such Series B
       Junior Securities in connection therewith.
 
           (f) Dividends payable on Series B Preferred Stock for any period less
       than one year shall be computed on the basis of a 360-day year consisting
       of twelve 30-day months and the actual number of days elapsed in the
       period for which such dividends are payable.
 
        4. LIQUIDATION PREFERENCE.
 
           (a) Upon any voluntary or involuntary liquidation, dissolution or
       winding up of the Corporation, the Holders of all shares of Series B
       Preferred Stock then outstanding shall be entitled to be paid out of the
       assets of the Corporation available for distribution to its stockholders
       an amount in cash equal to $10.00 per share, plus an amount equal to full
       cumulative dividends (whether or not earned or declared) accrued and
       unpaid thereon, including Additional Dividends, to the date of final
       distribution (the "Liquidation Preference") and no more, before any
       distribution is made on any Series B Junior Securities. If upon any
       voluntary or involuntary liquidation, dissolution or winding up of the
       Corporation, the application of all amounts available for payments with
       respect to Series B Preferred Stock and all other Series B Parity
       Securities would not result in payment in full of Series B Preferred
       Stock and such other Series B Parity Securities, the Holders and holders
       of Series B Parity Securities shall share equally and ratably in any
       distribution of assets of the Corporation in proportion to the full
       liquidation preference to which each is entitled. After payment in full
       pursuant to this paragraph A(4)(a), the Holders shall not be entitled to
       any further participation in any distribution in the event of
       liquidation, dissolution or winding up of the affairs of the Corporation.
 
           (b) For the purposes of this paragraph A(4), neither the voluntary
       sale, conveyance, exchange or transfer (for cash, shares of stock,
       securities or other consideration) of all or substantially all of the
       property or assets of the Corporation nor the consolidation, merger or
       other business combination of the Corporation with one or more
       corporations (whether or not the Corporation is the surviving
       corporation) shall be deemed to be a voluntary or involuntary
       liquidation, dissolution or winding up of the Corporation.
 
        5. REDEMPTION. The Company shall not have the right nor the power to,
    and the Holders shall not have the right to require the Company to, redeem
    any shares of Series B Preferred Stock. Notwithstanding the foregoing, this
    Paragraph A(5) shall not prohibit the Corporation from acquiring from any
    Holder, with such Holder's consent, any shares of Series B Preferred Stock
    held by such Holder.
 
        6. VOTING RIGHTS.
 
           (a) The Holders shall not be entitled or permitted to vote on any

       the holders of a majority of the outstanding shares of Series B Preferred
       Stock or the vote of the holders of a majority of the outstanding shares
       of Series B Preferred Stock at a meeting of the holders of Series B
       Preferred Stock called for such purpose, the Corporation shall not (a)
       create, authorize or issue any other class or series of stock entitled to
       a preference prior to Series B Preferred Stock upon any dividend or
       distribution or any liquidation, distribution of assets, dissolution or
       winding up of the Corporation, or (b) amend, alter or repeal any
       provision of the Corporation's Certificate of Incorporation so as to
       materially adversely affect the relative rights and preferences of the
       Series B Preferred Stock.
 
                                      D-13
<PAGE>
           (b) Without limiting the generality of the foregoing, in no event
       shall the Holders be entitled to vote (individually or as a class) on any
       merger or consolidation involving the Corporation, any sale of all or
       substantially all of the assets of the Corporation or any similar
       transaction.
 
           (c) In any case in which the Holders shall be entitled to vote
       pursuant to paragraph A(6)(a) above, each Holder shall be entitled to one
       vote for each share of Series B Preferred Stock held unless otherwise
       required by applicable law.
 
        7. CONVERSION OR EXCHANGE. The Holders shall not have any rights
    hereunder to convert such shares into or exchange such shares for shares of
    any other class or classes or of any other series of any class or classes of
    Capital Stock of the Corporation.
 
        8. REISSUANCE OF SERIES B PREFERRED STOCK. Shares of Series B Preferred
    Stock which have been issued and reacquired in any manner, including shares
    purchased, redeemed or exchanged, shall have the status of authorized and
    unissued shares of Preferred Stock and may be reissued as part of a new
    series of Preferred Stock to be created by resolution or resolutions of the
    Board of Directors or as part of any other series of Preferred Stock, all
    subject to the conditions or restrictions on issuance set forth in any
    resolution or resolutions adopted by the Board of Directors providing for
    the issuance of any series of Preferred Stock; except that the Corporation
    may reissue shares of Series B Preferred Stock which are reacquired by the
    Corporation from a Holder who is, or was, an employee or director of the
    Corporation (or its affiliates).
 
        9. BUSINESS DAY. If any payment shall be required by the terms hereof to
    be made on a day that is not a Business Day, such payment shall be made on
    the immediately succeeding Business Day.
 
        10. NO PREEMPTIVE RIGHTS. No Holder will possess any preemptive rights
    to subscribe for or acquire any unissued shares of Capital Stock of the
    Corporation (whether now or hereafter authorized) or securities of the
    Corporation convertible into or carrying a right to subscribe to or acquire
    shares of Capital Stock of the Corporation.
 
        11. PROHIBITIONS AND RESTRICTIONS IMPOSED BY SENIOR SECURITIES AND

       distributions on, or such repurchase or redemption of, such Series C
       Parity Securities (the "SERIES C PARITY PAYMENT DATE") and (ii) any such
       dividends are declared and paid pro rata so that the amounts of any
       dividends declared and paid per share on outstanding Series C Preferred
       Stock and each other share of Series C Parity Securities will in all
       cases bear to each other the same ratio that accrued and unpaid dividends
       (including any Accumulated Dividends) per share of outstanding Series C
       Preferred Stock and such other outstanding shares of Series C Parity
       Securities bear to each other.

       dividends upon any of the Series C Junior Securities. Such dividends on
       the Series C Preferred Stock shall be cumulative, whether or not earned
       or declared, so that if at any time full Accumulated Dividends on all
       shares of Series C Preferred Stock then outstanding for all Dividend
       Periods then elapsed have not been paid or set aside for payment, the
       amount of such unpaid dividends shall be paid before any sum shall be set
       aside for or applied by the Corporation to the purchase, redemption or
       other acquisition for value of any shares of Series C Junior Securities

       apart for payment on any Series C Junior Securities (the date of any such
       actions to be referred to as the "SERIES C JUNIOR PAYMENT DATE");
       PROVIDED, HOWEVER, that the foregoing shall not

       repurchases or acquisitions in respect of Series C Junior Securities
       payable in Series C Junior Securities and cash in lieu of fractional
       shares of such Series C Junior Securities in connection therewith.

       than one year shall be computed on the basis of a 360-day year consisting
       of twelve 30-day months and the actual number of days elapsed in the
       period for which such dividends are payable.
 
        4. LIQUIDATION PREFERENCE.

       other business combination of the Corporation with one or more
       corporations (whether or not the Corporation is the surviving
       corporation) shall be deemed to be a voluntary or involuntary
       liquidation, dissolution or winding up of the Corporation.

               the place or places where certificates for shares of Series C
               Preferred Stock are to be surrendered for redemption, in the
               manner and at the price designated, his, her or its certificate
               or certificates representing the shares of Series C Preferred

               to be redeemed shall cease to accumulate on such Redemption Date

           the Person whose name appears on such certificate or certificates as
           the owner thereof, and each surrendered certificate shall be canceled
           and retired. In the event that less than all of the shares
           represented by any such certificate are redeemed, a new certificate
           shall be issued representing the unredeemed shares.
 
               (iii) If a Redemption Notice has been mailed in accordance with
           paragraph A(5)(c) above, unless the Corporation defaults in the
           payment in full of the redemption

       in accordance with this paragraph (5) shall be deemed fulfilled if, on or

       trust Corporation, or an affiliate of a bank or trust Corporation such
       funds as are required to be delivered by the Corporation pursuant to this
       paragraph (5) upon the occurrence of the related redemption consideration
       sufficient to pay all accrued and unpaid dividends on the shares to be
       redeemed, in trust for the account of the Holders of the shares to be
       redeemed (and so as to be and continue to be available therefor), with
       irrevocable instructions and authority to such bank or trust Corporation
       that such shares and funds be delivered upon redemption of the shares of
       Series C Preferred Stock so called for redemption. Any interest accrued
       on such funds shall be paid to the Corporation from time to time. Upon
       surrender of the certificates pursuant to paragraph A(5)(c)(ii), each
       Holder shall thereupon be entitled to any funds payable pursuant to this

    (e) In the event Acquiror wishes to exercise the Option, it shall deliver to
each Stockholder at the address set forth on Schedule I, a written notice (the
date of which being herein referred to as the "Notice
 
                                      E-2
<PAGE>
Date") specifying (i) the total number of Shares it intends to purchase pursuant
to such exercise and (ii) a place and date not earlier than two business days
nor later than 30 calendar days from the Notice Date for the closing of such
purchase (the "Closing Date"); provided that if the closing of the purchase and
sale pursuant to the Option (the "Closing") cannot be consummated by reason of
any applicable judgment, decree, order, law or regulation, the period of time
that otherwise would run pursuant to this sentence shall run instead from the
date on which such restriction on consummation has expired or been terminated;
and, provided further that, without limiting the foregoing, if prior
notification to or approval of any regulatory authority is required in
connection with such purchase, Acquiror and, if applicable, each Stockholder,
shall promptly file the required notice or application for approval and shall
expeditiously process the same (and each Stockholder shall cooperate in a
commercially reasonable manner with Acquiror in the filing of any such notice or
application and the obtaining of any such approval), and the period of time that
otherwise would run pursuant to this sentence shall run instead from the date on
which, as the case may be, (i) any required notification period has expired or
been terminated or (ii) such approval has been obtained, and in either event,
any requisite waiting period has passed.
 
    (f) The Shares to be acquired pursuant to exercise of the Option shall be
allocated pro rata as between Common Shares and Preferred Shares and as among
each Stockholder based upon the number of Shares owned by them as set forth on
Schedule I. If Acquiror exercises the Option for no more than two million Shares
in the aggregate, the Stockholders may designate among themselves the
Stockholders who shall sell Shares to Acquiror pursuant to such partial exercise
of the Option, provided that (x) the aggregate number of Common Shares and
Preferred Shares to be sold to Acquiror pursuant to such exercise shall remain
the same as if there had been no designation and (y) such designation shall not
adversely affect the accounting treatment or economic impact of exercise of the
Option to Acquiror.
 
    (g) In the event Acquiror exercises the Option in part and acquires Shares
which represent a majority of the total voting power of the Company's capital
stock, on a fully-diluted basis, Acquiror agrees that it will exercise the
Option in respect of all the Shares set forth on Schedule I.
 
    4. Payment and Delivery of Certificates.
 
    (a) At the Closing, referred to in Section 3 hereof, Acquiror shall pay to
each Stockholder the aggregate Purchase Price for the Shares purchased from such
Stockholder pursuant to the exercise of the Option.
 
    (b) At such Closing, simultaneously with the delivery as provided in Section
4(a), each Stockholder shall transfer to Acquiror good, valid and marketable
title to, and shall deliver to Acquiror a certificate or certificates
representing, the number of Shares purchased by Acquiror, accompanied by
appropriate stock power(s) in form reasonably satisfactory to Acquiror), which
Shares shall be free and clear of all liens, claims, charges, security
interests, rights of first refusal or offer, proxies, voting trusts or
agreements, understandings or arrangements and other encumbrances of any kind
whatsoever other than any restrictions under the Securities Act or the Exchange
Act.
 
    (c) If at the time of transfer of any Common Shares or Preferred Shares
pursuant to any exercise of the Option, the Company shall have issued any share
purchase rights or similar securities to holders of the Common Shares or the
Preferred Shares, then each such Share shall also represent rights with terms
substantially the same as and at least as favorable to Acquiror as those issued
to the Stockholders.
 
    5. Authorizations, etc.
 
    (a) Each Stockholder hereby represents and warrants to Acquiror that:
 
        (i) The Stockholder has full power and authority to execute and deliver
    this Option Agreement and to consummate the transactions contemplated
    hereby;
 
        (ii) such execution, delivery and consummation have been authorized by
    the Stockholder, and no other proceedings or actions by the Stockholder are
    necessary therefor;
 
                                      E-3
<PAGE>
       (iii) this Option Agreement has been duly and validly executed and
    delivered and represents a valid and legally binding obligation of the
    Stockholder, enforceable against the Stockholder in accordance with its
    terms;
 
        (iv) the Stockholder is the Beneficial Owner (in addition to the
    registered owner) of, and has good, valid and marketable title to, the
    Common Shares and the Preferred Shares set forth opposite his name on
    Schedule I hereto, which are all of the Shares owned, directly or
    indirectly, by the Stockholder, and the Stockholder does not have any right
    to acquire any additional Shares; and
 
        (v) the Stockholder has taken all necessary action, and obtained all
    necessary consents and authorizations (except as may be required by the HSR
    Act), to authorize and permit it to sell the Shares upon exercise of the
    Option, all of which Shares, upon sale pursuant hereto, and shall be
    delivered free and clear of all claims, liens, encumbrances, restrictions
    and security interests, rights of first refusal or offer, and not subject to
    any preemptive rights.
 
    (b) Acquiror hereby represents and warrants to each Stockholder that:
 
        (i) Acquiror has full corporate power and authority to execute and
    deliver this Option Agreement and to consummate the transactions
    contemplated hereby;
 
        (ii) such execution, delivery and consummation have been authorized by
    all requisite corporate action by Acquiror, and no other corporate
    proceedings are necessary therefor;
 
       (iii) this Option Agreement has been duly and validly executed and
    delivered and represents a valid and legally binding obligation of Acquiror,
    enforceable against Acquiror in accordance with its terms; and
 
        (iv) any Shares or other securities acquired by Acquiror upon exercise
    of the Option will not be taken with a view to the public distribution
    thereof and will not be transferred or otherwise disposed of except in
    compliance with the Securities Act.
 
        (v) prior to the Closing, Acquiror will have taken all necessary action
    and obtained all necessary consents and authorizations (except as may be
    required by the HSR Act), to authorize and permit it to purchase the Shares
    upon exercise of the Option.
 
    6. Adjustment upon Changes in Capitalization.
 
    In the event of any change in the Common Shares or Preferred Shares by
reason of a stock dividend, split-up, recapitalization, merger, consolidation,
reorganization, combination, exchange of shares or similar transaction, the type
and number of shares or securities subject to the Option, and the Purchase Price
therefor, shall be adjusted appropriately so that Acquiror shall receive upon
exercise of the Option the same class and number of outstanding shares or other
securities or property that Acquiror would have received in respect of the
Common Shares or Preferred Shares if the Option had been exercised immediately
prior to such event, or the record date therefor, as applicable.
 
    7. Severability.
 
    Any term, provision, covenant or restriction contained in this Option
Agreement held by a court or other Governmental Entity of competent jurisdiction
to be invalid, void or unenforceable, shall be ineffective to the extent of such
invalidity, voidness or unenforceability, but neither the remaining terms,
provisions, covenants or restrictions contained in this Option Agreement, nor
the validity or enforceability thereof in any other jurisdiction shall be
affected or impaired thereby. Any term, provision, covenant or restriction
contained in this Option Agreement that is so found to be so broad as to be
unenforceable shall be interpreted to be as broad as is enforceable.
 
                                      E-4

in whole or in part to any person; provided that no such assignment shall
relieve Acquiror of its obligations hereunder. The terms and conditions of this

hereto and their respective successors and permitted assigns. Nothing in this

Agreement, except as expressly provided herein.

Agreement and, in the case of the Stockholder, at the address set forth in the
Stockholder Agreement.

each such counterpart shall be deemed to be an original instrument, but both
such counterparts together shall constitute but one agreement.

Agreement against such non-performing party shall be entitled to specific
performance and injunctive and other equitable relief, and the parties hereto
further agree to waive any requirement for the securing or posting of any bond

relief. This provision is without prejudice to any other rights that either
party hereto may have against the other party hereto for any failure to perform

violation of applicable law, rule or regulation.
 
    (i) Regulatory Approvals. If, in connection with the exercise of the Option
under Section 3, prior notification to or approval of any Governmental Entity is
required, then the required notice or application for approval shall be promptly

that otherwise would run pursuant hereto (if any) shall run instead from the
date on which any such required notification period has expired or been
terminated or such approval has been obtained, and in either event, any

c/o Bruckmann, Rosser & Sherrill & Co., Inc.
126 East 56th Street
New York, NY 10022
 
    Re: Stockholder Agreement
 
Dear Sirs:
 
    The undersigned (the "Stockholder") understands that MQ Acquisition
Corporation, a Delaware corporation ("Acquiror") and Mediq Incorporated, a
Delaware corporation (the "Company") are entering into an Agreement and Plan of
Merger, dated the date hereof, as the same may be amended from time to time (the
"Merger Agreement"), providing for, among other things, the merger of Acquiror
with and into the Company on the terms and conditions set forth therein (the
"Merger").
 
    The Stockholder is a stockholder of the Company and is entering into this
letter agreement (the "Stockholder Agreement") to induce you to enter into the
Merger Agreement and to consummate the transactions contemplated thereby.
Capitalized terms used but not defined herein shall have the same meanings as in
the Merger Agreement.
 
    The Stockholder confirms its agreement with you as follows:
 
        1. The Stockholder represents, warrants and agrees that Schedule I
    annexed hereto sets forth the Common Shares and Preferred Shares of which
    the Stockholder or its affiliates (as defined under the Securities Exchange
    Act of 1934, as amended) are the record or beneficial owner and that the
    Stockholder and its affiliates are on the date hereof the lawful owners of
    the number of Shares set forth in Schedule I beside the name of the
    Stockholder or such other person. Except as set forth in Schedule I, neither
    the Stockholder nor any of its affiliates, own or hold any rights to acquire
    any additional shares of the capital stock of the Company (by exercise of
    stock options or otherwise) or any interest therein or any voting rights
    with respect to any additional Shares. The Stockholder, together with other
    persons who are signatories to this Stockholder Agreement or letter
    agreements with Acquiror containing substantially the same terms and
    conditions as set forth herein, has sole voting power and sole power to
    issue instructions with respect to the matters set forth herein, sole power
    of disposition, sole power of conversion, sole power to demand appraisal
    rights and sole power to engage in the actions set forth herein, in each
    case with respect to the Shares set forth on Schedule I hereto beside the
    name of the Stockholder or such other person.
 
        2. The Stockholder agrees that it will not, will not permit any company,
    trust or other person or entity controlled by the Stockholder to, and will
    not permit any of its affiliates to, contract to sell, sell or otherwise
    transfer or dispose of any Shares or any interest therein or securities
    convertible therein to or any voting rights with respect thereto, other than
    (i) pursuant to the Merger, (ii) pursuant to the Option Agreement dated of
    even date herewith between Acquiror and the undersigned (iii) with your
    prior written consent. The Stockholder agrees that it shall not convert any
    Preferred Shares into Common Shares or take any other action which
    diminishes the benefits of this Stockholder Agreement to the Acquiror.
 
        3. The Stockholder agrees to, and to cause any company, trust or other
    person or entity controlled by the Stockholder to, cooperate fully with you
    in connection with the Merger Agreement, the Option Agreement, this
    Stockholders Agreement and the transactions contemplated thereby and hereby.
    The Stockholder agrees that it will not, and will not permit any such
    company, trust or other
 
                                      F-1
<PAGE>
    entity or person to, and will not authorize any of its affiliates to,
    directly or indirectly (including through its officers, directors, employees
    or other representatives) to solicit, initiate, encourage or facilitate, or
    furnish or disclose non-public information in furtherance of, any inquiries
    or the making of any proposal with respect to any recapitalization, merger,
    consolidation or other business combination involving the Company, or the
    acquisition of any capital stock or any material portion of the assets
    (except for acquisition of assets in the ordinary course of business
    consistent with past practice and not material in the aggregate to the
    Company) of the Company, or any combination of the foregoing (a "Competing
    Transaction"), or negotiate, explore or otherwise engage in discussions with
    any person (other than Acquiror and its affiliates, or their respective
    directors, officers, employees, agents and representatives) with respect to
    any Competing Transaction or enter into any agreement, arrangement or
    understanding with respect to any Competing Transaction or agree to or
    otherwise assist in the effectuation of any Competing Transaction; provided,
    however, that nothing herein shall require the Stockholder to prevent or
    restrict any director or trustee of the Stockholder who is a director or
    officer of the Company from taking any action in his capacity as a director
    or officer of the Company to the extent such director or officer would be
    permitted to take such action under the Merger Agreement.
 
        4. The Stockholder agrees that all of the Shares beneficially owned by
    the Stockholder, or over which the Stockholder has voting power or control,
    directly or indirectly (including any Shares beneficial ownership of which
    is acquired by the Stockholder after the date hereof), at the record date
    for any meeting of the Company's stockholders, however called, or in
    connection with any written consent of the stockholders of the Company,
    shall be voted (or caused to be voted) (i) in favor of the Merger, the
    execution and delivery by the Company of the Merger Agreement and the
    approval of the terms thereof and each of the other actions contemplated by
    the Merger Agreement, this Stockholder Agreement and the Option Agreement
    and any actions required in furtherance hereof and thereof; (ii) against any
    action or agreement that would result in a breach in any material respect of
    any covenant, representation or warranty or any other obligation of the
    Company under the Merger Agreement or under this Stockholder Agreement or
    the Option Agreement; and (iii) except as otherwise agreed to in writing in
    advance by Acquiror, against the following actions (other than the Merger
    and the transactions with you or your affiliates contemplated by the Merger
    Agreement): (1) any extraordinary corporate transaction, such as a merger,
    consolidation or other business combination involving the Company or its
    Subsidiaries; (2) any sale, lease or transfer of a material amount of assets
    of the Company or its Subsidiaries or a reorganization, recapitalization,
    dissolution or liquidation of the Company or its Subsidiaries; (3) (a)
    subject to Section 7 hereof, any change in the majority of the Board of
    Directors of the Company; (b) any material change in the present
    capitalization of the Company or any amendment of the Company's Certificate
    of Incorporation or Bylaws; (c) any other material change in the Company's
    corporate structure or business; or (d) any other action, which is intended,
    or could reasonably be expected, to impede, interfere with, delay, postpone,
    discourage or materially adversely affect the contemplated economic benefits
    to Acquiror of the Merger or the transactions contemplated by the Merger
    Agreement, this Stockholder Agreement or the Option Agreement. The
    Stockholder shall not enter into any agreement or understanding with any
    person or entity to vote or give instructions in any manner inconsistent
    with clauses (i), (ii) or (iii) of the preceding sentence.
 
        5. The Stockholder hereby grants to, and appoints, Acquiror and its
    officers, and any other designee of Acquiror, each of them individually, the
    Stockholder's irrevocable proxy and attorney-in-fact (with full power of
    substitution) to vote (as indicated in paragraph 4 above) the Shares listed
    on Schedule I hereto beside the name of the Stockholder, and any Shares
    beneficial ownership of which is acquired by the Stockholder after the date
    hereof, at a duly called meeting of the Company's stockholders (and, in the
    event the Stockholder has breached its obligations under this Stockholder
    Agreement or the Option Agreement or the Company breaches its obligation
    under the Merger Agreement to call and hold or otherwise fails to hold the
    Special Meeting, by duly executed written
 
                                      F-2
<PAGE>
    consent of stockholders). The Stockholder intends this proxy to be
    irrevocable, subject to Section 16 hereof, and coupled with an interest and
    will take such further action and execute such other instruments as may be
    necessary to effectuate the intent of this proxy and hereby revokes any
    proxy previously granted by the Stockholder with respect to the
    Stockholder's Shares. The Stockholder agrees that if requested by Acquiror,
    the Stockholder will not attend or vote any Shares beneficially owned by the
    Stockholder at any annual or special meeting of stockholders or execute any
    written consent of stockholders.
 
        6. The Stockholder has the legal capacity, power and authority to enter
    into and perform all of such Stockholder's obligations under this
    Stockholder Agreement. The execution, delivery and performance of this
    Stockholder Agreement by such Stockholder will not violate any other
    agreement to which such Stockholder is a party including, without
    limitation, any trust agreement, voting agreement, stockholders agreement or
    voting trust. This Stockholder Agreement has been duly and validly executed
    and delivered by the Stockholder, and is enforceable against the Stockholder
    in accordance with its terms. There is no beneficiary or holder of any
    interest of the Stockholder or any trust of which the Stockholder is a
    trustee whose consent is required for the execution and delivery of this
    Stockholder Agreement or the consummation of the transactions contemplated
    hereby. If the Stockholder is married and the Stockholder's Shares
    constitute community property, this letter agreement has been duly
    authorized, executed and delivered by, and constitutes a valid and binding
    agreement of, the Stockholder's spouse, enforceable against such spouse in
    accordance with its terms.
 
        7. Except for filings under the Hart-Scott-Rodino Antitrust Improvements
    Act of 1976, as amended, and with the Securities and Exchange Commission if
    applicable, no filing with, and no permit, authorization, consent or
    approval of, any state or federal public body or authority is necessary for
    the execution of this Stockholder Agreement by the Stockholder and the
    consummation by the Stockholder of the transactions contemplated hereby.
 
        8. The Stockholder's Shares (as listed on Schedule I) and the
    certificates representing such Shares are now and at all times during the
    term hereof will be held by the Stockholder, or by a nominee or custodian
    for the benefit of the Stockholder, free and clear of all liens, claims,
    security interests, rights of first refusal or offer, proxies, voting trusts
    or agreements, understandings or arrangements or any other encumbrances
    whatsoever, except for any such encumbrances or proxies arising hereunder.
 
        9. No broker, investment banker, financial advisor or other person is
    entitled to any broker's, finder's, financial advisor's or other similar fee
    or commission in connection with the transactions contemplated hereby based
    upon arrangements made by the Stockholder.
 
        10. The Stockholder agrees that damages are an inadequate remedy for the
    breach by the Stockholder of any term or condition of this Stockholder
    Agreement and that Acquiror shall be entitled, without limitation of other
    available rights or remedies, to specific performance, a temporary
    restraining order and preliminary and permanent injunctive relief in order
    to enforce the Stockholder's agreements herein.
 
        11. The Stockholder agrees that this Stockholder Agreement and the
    obligations hereunder shall attach to such Stockholder's Shares and shall be
    binding upon any person or entity to which legal or beneficial ownership of
    such Shares shall pass, whether by operation of law or otherwise, including
    without limitation such Stockholder's heirs, guardians, administrators or
    successors.
 
        12. From time to time, at the other party's request and without further
    consideration, each party hereto shall execute and deliver such additional
    documents and take all such further action as may be necessary or desirable
    to consummate and make effective, in the most expeditious manner
    practicable, the transactions contemplated by this Stockholder Agreement.

        13. This Stockholder Agreement may not be modified, amended, altered or
    supplemented, except upon the execution and delivery of a written agreement
    executed by the parties hereto.
 
        14. This Stockholder Agreement shall be governed by and construed in
    accordance with the laws of the State of Delaware, regardless of the laws
    that might otherwise govern under applicable principles of conflicts of laws
    thereof.
 
        15. Whenever possible, each provision or portion of any provision of
    this Stockholder Agreement will be interpreted in such manner as to be
    effective and valid under applicable law but if any provision or portion of
    any provision of this Stockholder Agreement is held to be invalid, illegal
    or unenforceable in any respect under any applicable law or rule in any
    jurisdiction, such invalidity, illegality or unenforceability will not
    affect any other provision or portion of any provision in such jurisdiction,
    and this Stockholder Agreement will be reformed, construed and enforced in
    such jurisdiction as if such invalid, illegal or unenforceable provision or
    portion of any provision had never been contained herein. Each party hereto
    irrevocably and unconditionally consents and submits to the exclusive
    jurisdiction of the courts of the State of Delaware and of the United States
    of America located in the State of Delaware for any actions, suits or
    proceedings arising out of or relating to this agreement and the
    transactions contemplated hereby, and further agrees that service of any
    process, summons, notice or document by U.S. registered or certified mail to
    the Stockholder at Duane Morris & Heckscher LLP, One Liberty Place,

    of any action, suit or proceeding arising out of this Stockholder Agreement
    or the transactions contemplated hereby, in the courts of the State of
    Delaware located in Wilmington, Delaware or the United States of America
    located in Wilmington, Delaware, and hereby further irrevocably and
    unconditionally waives and agrees not to plead or claim in any such court
    that any such action, suit or proceeding brought in any such court has been
    brought in an inconvenient forum.
 
        16. This Stockholder Agreement may be terminated at the option of any
    party at any time after the Termination Date (as defined in the Option
    Agreement). Please confirm that the foregoing correctly states the
    understanding between us by signing and returning to me a counterpart
    hereof, whereupon this will become a legal and binding obligation.

MQ Acquisition Corporation
c/o Bruckmann, Rosser & Sherrill & Co., Inc.
126 East 56th Street
New York, NY 10022
 
    Re: Stockholder Agreement
 
Dear Sirs:
 
    The undersigned (the "Stockholder") understands that MQ Acquisition
Corporation, a Delaware corporation ("Acquiror") and Mediq Incorporated, a
Delaware corporation (the "Company") are entering into an Agreement and Plan of
Merger, dated the date hereof, as the same may be amended from time to time (the
"Merger Agreement"), providing for, among other things, the merger of Acquiror
with and into the Company on the terms and conditions set forth therein (the
"Merger").
 
    The Stockholder is a stockholder of the Company and is entering into this
letter agreement (the "Stockholder Agreement") to induce you to enter into the
Merger Agreement and to consummate the transactions contemplated thereby.
Capitalized terms used but not defined herein shall have the same meanings as in
the Merger Agreement.
 
    The Stockholder confirms its agreement with you as follows:
 
        1. The Stockholder represents, warrants and agrees that Schedule I
    annexed hereto sets forth the Common Shares and Preferred Shares of which
    the Stockholder or its affiliates (as defined under the Securities Exchange
    Act of 1934, as amended) are the record or beneficial owner and that the
    Stockholder and its affiliates are on the date hereof the lawful owners of
    the number of Shares set forth in Schedule I beside the name of the
    Stockholder or such other person. Except as set forth in Schedule I, neither
    the Stockholder nor any of its affiliates, own or hold any rights to acquire
    any additional shares of the capital stock of the Company (by exercise of
    stock options or otherwise) or any interest therein or any voting rights
    with respect to any additional Shares. The Stockholder, together with other
    persons who are signatories to this Stockholder Agreement or letter
    agreements with Acquiror containing substantially the same terms and
    conditions as set forth herein, has sole voting power and sole power to
    issue instructions with respect to the matters set forth herein, sole power
    of disposition, sole power of conversion, sole power to demand appraisal
    rights and sole power to engage in the actions set forth herein, in each
    case with respect to the Shares set forth on Schedule I hereto beside the
    name of the Stockholder or such other person.
 
        2. The Stockholder agrees that it will not, will not permit any company,
    trust or other person or entity controlled by the Stockholder to, and will
    not permit any of its affiliates to, contract to sell, sell or otherwise
    transfer or dispose of any Shares or any interest therein or securities
    convertible therein to or any voting rights with respect thereto, other than
    (i) pursuant to the Merger, (ii) pursuant to the Option Agreement dated of
    even date herewith between Acquiror and the undersigned (iii) with your
    prior written consent. The Stockholder agrees that it shall not convert any
    Preferred Shares into Common Shares or take any other action which
    diminishes the benefits of this Stockholder Agreement to the Acquiror.
 
        3. The Stockholder agrees to, and to cause any company, trust or other
    person or entity controlled by the Stockholder to, cooperate fully with you
    in connection with the Merger Agreement, the Option Agreement, this
    Stockholders Agreement and the transactions contemplated thereby and hereby.
    The Stockholder agrees that it will not, and will not permit any such
    company, trust or other entity or person to, and will not authorize any of
    its affiliates to, directly or indirectly (including through its officers,
    directors, employees or other representatives) to solicit, initiate,
    encourage or
 
                                      F-6
<PAGE>
    facilitate, or furnish or disclose non-public information in furtherance of,
    any inquiries or the making of any proposal with respect to any
    recapitalization, merger, consolidation or other business combination
    involving the Company, or the acquisition of any capital stock or any
    material portion of the assets (except for acquisition of assets in the
    ordinary course of business consistent with past practice and not material
    in the aggregate to the Company) of the Company, or any combination of the
    foregoing (a "Competing Transaction"), or negotiate, explore or otherwise
    engage in discussions with any person (other than Acquiror and its
    affiliates, or their respective directors, officers, employees, agents and
    representatives) with respect to any Competing Transaction or enter into any
    agreement, arrangement or understanding with respect to any Competing
    Transaction or agree to or otherwise assist in the effectuation of any
    Competing Transaction; provided, however, that nothing herein shall require
    the Stockholder to prevent or restrict any director or trustee of the
    Stockholder who is a director or officer of the Company from taking any
    action in his capacity as a director or officer of the Company to the extent
    such director or officer would be permitted to take such action under the
    Merger Agreement.
 
        4. The Stockholder agrees that all of the Shares beneficially owned by
    the Stockholder, or over which the Stockholder has voting power or control,
    directly or indirectly (including any Shares beneficial ownership of which
    is acquired by the Stockholder after the date hereof), at the record date
    for any meeting of the Company's stockholders, however called, or in
    connection with any written consent of the stockholders of the Company,
    shall be voted (or caused to be voted) (i) in favor of the Merger, the
    execution and delivery by the Company of the Merger Agreement and the
    approval of the terms thereof and each of the other actions contemplated by
    the Merger Agreement, this Stockholder Agreement and the Option Agreement
    and any actions required in furtherance hereof and thereof; (ii) against any
    action or agreement that would result in a breach in any material respect of
    any covenant, representation or warranty or any other obligation of the
    Company under the Merger Agreement or under this Stockholder Agreement or
    the Option Agreement; and (iii) except as otherwise agreed to in writing in
    advance by Acquiror, against the following actions (other than the Merger
    and the transactions with you or your affiliates contemplated by the Merger
    Agreement): (1) any extraordinary corporate transaction, such as a merger,
    consolidation or other business combination involving the Company or its
    Subsidiaries; (2) any sale, lease or transfer of a material amount of assets
    of the Company or its Subsidiaries or a reorganization, recapitalization,
    dissolution or liquidation of the Company or its Subsidiaries; (3) (a)
    subject to Section 7 hereof, any change in the majority of the Board of
    Directors of the Company; (b) any material change in the present
    capitalization of the Company or any amendment of the Company's Certificate
    of Incorporation or Bylaws; (c) any other material change in the Company's
    corporate structure or business; or (d) any other action, which is intended,
    or could reasonably be expected, to impede, interfere with, delay, postpone,
    discourage or materially adversely affect the contemplated economic benefits
    to Acquiror of the Merger or the transactions contemplated by the Merger
    Agreement, this Stockholder Agreement or the Option Agreement. The
    Stockholder shall not enter into any agreement or understanding with any
    person or entity to vote or give instructions in any manner inconsistent
    with clauses (i), (ii) or (iii) of the preceding sentence.
 
        5. The Stockholder hereby grants to, and appoints, Acquiror and its
    officers, and any other designee of Acquiror, each of them individually, the
    Stockholder's irrevocable proxy and attorney-in-fact (with full power of
    substitution) to vote (as indicated in paragraph 4 above) the Shares listed
    on Schedule I hereto beside the name of the Stockholder, and any Shares
    beneficial ownership of which is acquired by the Stockholder after the date
    hereof, at a duly called meeting of the Company's stockholders (and, in the
    event the Stockholder has breached its obligations under this Stockholder
    Agreement or the Option Agreement or the Company breaches its obligation
    under the Merger Agreement to call and hold or otherwise fails to hold the
    Special Meeting, by duly executed written consent of stockholders). The
    Stockholder intends this proxy to be irrevocable, subject to Section 16
    hereof, and coupled with an interest and will take such further action and
    execute such other
 
                                      F-7
<PAGE>
    instruments as may be necessary to effectuate the intent of this proxy and
    hereby revokes any proxy previously granted by the Stockholder with respect
    to the Stockholder's Shares. The Stockholder agrees that if requested by
    Acquiror, the Stockholder will not attend or vote any Shares beneficially
    owned by the Stockholder at any annual or special meeting of stockholders or
    execute any written consent of stockholders.
 
        6. The Stockholder has the legal capacity, power and authority to enter
    into and perform all of such Stockholder's obligations under this
    Stockholder Agreement. The execution, delivery and performance of this
    Stockholder Agreement by such Stockholder will not violate any other
    agreement to which such Stockholder is a party including, without
    limitation, any trust agreement, voting agreement, stockholders agreement or
    voting trust. This Stockholder Agreement has been duly and validly executed
    and delivered by the Stockholder, and is enforceable against the Stockholder
    in accordance with its terms. There is no beneficiary or holder of any
    interest of the Stockholder or any trust of which the Stockholder is a
    trustee whose consent is required for the execution and delivery of this
    Stockholder Agreement or the consummation of the transactions contemplated
    hereby. If the Stockholder is married and the Stockholder's Shares
    constitute community property, this letter agreement has been duly
    authorized, executed and delivered by, and constitutes a valid and binding
    agreement of, the Stockholder's spouse, enforceable against such spouse in
    accordance with its terms.
 
        7. Except for filings under the Hart-Scott-Rodino Antitrust Improvements
    Act of 1976, as amended, and with the Securities and Exchange Commission if
    applicable, no filing with, and no permit, authorization, consent or
    approval of, any state or federal public body or authority is necessary for
    the execution of this Stockholder Agreement by the Stockholder and the
    consummation by the Stockholder of the transactions contemplated hereby.
 
        8. The Stockholder's Shares (as listed on Schedule I) and the
    certificates representing such Shares are now and at all times during the
    term hereof will be held by the Stockholder, or by a nominee or custodian
    for the benefit of the Stockholder, free and clear of all liens, claims,
    security interests, rights of first refusal or offer, proxies, voting trusts
    or agreements, understandings or arrangements or any other encumbrances
    whatsoever, except for any such encumbrances or proxies arising hereunder.
 
        9. No broker, investment banker, financial advisor or other person is
    entitled to any broker's, finder's, financial advisor's or other similar fee
    or commission in connection with the transactions contemplated hereby based
    upon arrangements made by the Stockholder.
 
        10. The Stockholder agrees that damages are an inadequate remedy for the
    breach by the Stockholder of any term or condition of this Stockholder
    Agreement and that Acquiror shall be entitled, without limitation of other
    available rights or remedies, to specific performance, a temporary
    restraining order and preliminary and permanent injunctive relief in order
    to enforce the Stockholder's agreements herein.
 
        11. The Stockholder agrees that this Stockholder Agreement and the
    obligations hereunder shall attach to such Stockholder's Shares and shall be
    binding upon any person or entity to which legal or beneficial ownership of
    such Shares shall pass, whether by operation of law or otherwise, including
    without limitation such Stockholder's heirs, guardians, administrators or
    successors.
 
        12. From time to time, at the other party's request and without further
    consideration, each party hereto shall execute and deliver such additional
    documents and take all such further action as may be necessary or desirable
    to consummate and make effective, in the most expeditious manner
    practicable, the transactions contemplated by this Stockholder Agreement.
 
        13. This Stockholder Agreement may not be modified, amended, altered or
    supplemented, except upon the execution and delivery of a written agreement
    executed by the parties hereto.
 
                                      F-8
<PAGE>
        14. This Stockholder Agreement shall be governed by and construed in
    accordance with the laws of the State of Delaware, regardless of the laws
    that might otherwise govern under applicable principles of conflicts of laws
    thereof.
 
        15. Whenever possible, each provision or portion of any provision of
    this Stockholder Agreement will be interpreted in such manner as to be
    effective and valid under applicable law but if any provision or portion of
    any provision of this Stockholder Agreement is held to be invalid, illegal
    or unenforceable in any respect under any applicable law or rule in any
    jurisdiction, such invalidity, illegality or unenforceability will not
    affect any other provision or portion of any provision in such jurisdiction,
    and this Stockholder Agreement will be reformed, construed and enforced in
    such jurisdiction as if such invalid, illegal or unenforceable provision or
    portion of any provision had never been contained herein. Each party hereto
    irrevocably and unconditionally consents and submits to the exclusive
    jurisdiction of the courts of the State of Delaware and of the United States
    of America located in the State of Delaware for any actions, suits or
    proceedings arising out of or relating to this agreement and the
    transactions contemplated hereby, and further agrees that service of any
    process, summons, notice or document by U.S. registered or certified mail to
    the Stockholder at Duane Morris & Heckscher LLP, One Liberty Place,
    Philadelphia, PA 19103, Attention: Sheldon M. Bonovitz or Frederick W.

MQ Acquisition Corporation
c/o Bruckmann, Rosser & Sherrill & Co., Inc.
126 East 56th Street
New York, NY 10022
 
    Re: Stockholder Agreement
 
Dear Sirs:
 
    The undersigned (the "Stockholder") understands that MQ Acquisition
Corporation, a Delaware corporation ("Acquiror") and Mediq Incorporated, a
Delaware corporation (the "Company") are entering into an Agreement and Plan of
Merger, dated the date hereof, as the same may be amended from time to time (the
"Merger Agreement"), providing for, among other things, the merger of Acquiror
with and into the Company on the terms and conditions set forth therein (the
"Merger").
 
    The Stockholder is a stockholder of the Company and is entering into this
letter agreement (the "Stockholder Agreement") to induce you to enter into the
Merger Agreement and to consummate the transactions contemplated thereby.
Capitalized terms used but not defined herein shall have the same meanings as in
the Merger Agreement.
 
    The Stockholder confirms its agreement with you as follows:
 
        1. The Stockholder represents, warrants and agrees that Schedule I
    annexed hereto sets forth the Common Shares and Preferred Shares of which
    the Stockholder or its affiliates (as defined under the Securities Exchange
    Act of 1934, as amended) are the record or beneficial owner and that the
    Stockholder and its affiliates are on the date hereof the lawful owners of
    the number of Shares set forth in Schedule I beside the name of the
    Stockholder or such other person. Except as set forth in Schedule I, neither
    the Stockholder nor any of its affiliates, own or hold any rights to acquire
    any additional shares of the capital stock of the Company (by exercise of
    stock options or otherwise) or any interest therein or any voting rights
    with respect to any additional Shares. The Stockholder, together with other
    persons who are signatories to this Stockholder Agreement or letter
    agreements with Acquiror containing substantially the same terms and
    conditions as set forth herein, has sole voting power and sole power to
    issue instructions with respect to the matters set forth herein, sole power
    of disposition, sole power of conversion, sole power to demand appraisal
    rights and sole power to engage in the actions set forth herein, in each
    case with respect to the Shares set forth on Schedule I hereto beside the
    name of the Stockholder or such other person.
 
        2. The Stockholder agrees that it will not, will not permit any company,
    trust or other person or entity controlled by the Stockholder to, and will
    not permit any of its affiliates to, contract to sell, sell or otherwise
    transfer or dispose of any Shares or any interest therein or securities
    convertible therein to or any voting rights with respect thereto, other than
    (i) pursuant to the Merger, (ii) pursuant to the Option Agreement dated of
    even date herewith between Acquiror and the undersigned (iii) with your
    prior written consent. The Stockholder agrees that it shall not convert any
    Preferred Shares into Common Shares or take any other action which
    diminishes the benefits of this Stockholder Agreement to the Acquiror.
 
        3. The Stockholder agrees to, and to cause any company, trust or other
    person or entity controlled by the Stockholder to, cooperate fully with you
    in connection with the Merger Agreement, the Option Agreement, this
    Stockholders Agreement and the transactions contemplated thereby and hereby.
    The Stockholder agrees that it will not, and will not permit any such
    company, trust or other entity or person to, and will not authorize any of
    its affiliates to, directly or indirectly (including
 
                                      F-11
<PAGE>
    through its officers, directors, employees or other representatives) to
    solicit, initiate, encourage or facilitate, or furnish or disclose
    non-public information in furtherance of, any inquiries or the making of any
    proposal with respect to any recapitalization, merger, consolidation or
    other business combination involving the Company, or the acquisition of any
    capital stock or any material portion of the assets (except for acquisition
    of assets in the ordinary course of business consistent with past practice
    and not material in the aggregate to the Company) of the Company, or any
    combination of the foregoing (a "Competing Transaction"), or negotiate,
    explore or otherwise engage in discussions with any person (other than
    Acquiror and its affiliates, or their respective directors, officers,
    employees, agents and representatives) with respect to any Competing
    Transaction or enter into any agreement, arrangement or understanding with
    respect to any Competing Transaction or agree to or otherwise assist in the
    effectuation of any Competing Transaction; provided, however, that nothing
    herein shall require the Stockholder to prevent or restrict any director or
    trustee of the Stockholder who is a director or officer of the Company from
    taking any action in his capacity as a director or officer of the Company to
    the extent such director or officer would be permitted to take such action
    under the Merger Agreement.
 
        4. The Stockholder agrees that all of the Shares beneficially owned by
    the Stockholder, or over which the Stockholder has voting power or control,
    directly or indirectly (including any Shares beneficial ownership of which
    is acquired by the Stockholder after the date hereof), at the record date
    for any meeting of the Company's stockholders, however called, or in
    connection with any written consent of the stockholders of the Company,
    shall be voted (or caused to be voted) (i) in favor of the Merger, the
    execution and delivery by the Company of the Merger Agreement and the
    approval of the terms thereof and each of the other actions contemplated by
    the Merger Agreement, this Stockholder Agreement and the Option Agreement
    and any actions required in furtherance hereof and thereof; (ii) against any
    action or agreement that would result in a breach in any material respect of
    any covenant, representation or warranty or any other obligation of the
    Company under the Merger Agreement or under this Stockholder Agreement or
    the Option Agreement; and (iii) except as otherwise agreed to in writing in
    advance by Acquiror, against the following actions (other than the Merger
    and the transactions with you or your affiliates contemplated by the Merger
    Agreement): (1) any extraordinary corporate transaction, such as a merger,
    consolidation or other business combination involving the Company or its
    Subsidiaries; (2) any sale, lease or transfer of a material amount of assets
    of the Company or its Subsidiaries or a reorganization, recapitalization,
    dissolution or liquidation of the Company or its Subsidiaries; (3) (a)
    subject to Section 7 hereof, any change in the majority of the Board of
    Directors of the Company; (b) any material change in the present
    capitalization of the Company or any amendment of the Company's Certificate
    of Incorporation or Bylaws; (c) any other material change in the Company's
    corporate structure or business; or (d) any other action, which is intended,
    or could reasonably be expected, to impede, interfere with, delay, postpone,
    discourage or materially adversely affect the contemplated economic benefits
    to Acquiror of the Merger or the transactions contemplated by the Merger
    Agreement, this Stockholder Agreement or the Option Agreement. The
    Stockholder shall not enter into any agreement or understanding with any
    person or entity to vote or give instructions in any manner inconsistent
    with clauses (i), (ii) or (iii) of the preceding sentence.
 
        5. The Stockholder hereby grants to, and appoints, Acquiror and its
    officers, and any other designee of Acquiror, each of them individually, the
    Stockholder's irrevocable proxy and attorney-in-fact (with full power of
    substitution) to vote (as indicated in paragraph 4 above) the Shares listed
    on Schedule I hereto beside the name of the Stockholder, and any Shares
    beneficial ownership of which is acquired by the Stockholder after the date
    hereof, at a duly called meeting of the Company's stockholders (and, in the
    event the Stockholder has breached its obligations under this Stockholder
    Agreement or the Option Agreement or the Company breaches its obligation
    under the Merger Agreement to call and hold or otherwise fails to hold the
    Special Meeting, by duly executed written consent of stockholders). The
    Stockholder intends this proxy to be irrevocable, subject to Section 16
 
                                      F-12
<PAGE>
    hereof, and coupled with an interest and will take such further action and
    execute such other instruments as may be necessary to effectuate the intent
    of this proxy and hereby revokes any proxy previously granted by the
    Stockholder with respect to the Stockholder's Shares. The Stockholder agrees
    that if requested by Acquiror, the Stockholder will not attend or vote any
    Shares beneficially owned by the Stockholder at any annual or special
    meeting of stockholders or execute any written consent of stockholders.
 
        6. The Stockholder has the legal capacity, power and authority to enter
    into and perform all of such Stockholder's obligations under this
    Stockholder Agreement. The execution, delivery and performance of this
    Stockholder Agreement by such Stockholder will not violate any other
    agreement to which such Stockholder is a party including, without
    limitation, any trust agreement, voting agreement, stockholders agreement or
    voting trust. This Stockholder Agreement has been duly and validly executed
    and delivered by the Stockholder, and is enforceable against the Stockholder
    in accordance with its terms. There is no beneficiary or holder of any
    interest of the Stockholder or any trust of which the Stockholder is a
    trustee whose consent is required for the execution and delivery of this
    Stockholder Agreement or the consummation of the transactions contemplated
    hereby. If the Stockholder is married and the Stockholder's Shares
    constitute community property, this letter agreement has been duly
    authorized, executed and delivered by, and constitutes a valid and binding
    agreement of, the Stockholder's spouse, enforceable against such spouse in
    accordance with its terms.
 
        7. Except for filings under the Hart-Scott-Rodino Antitrust Improvements
    Act of 1976, as amended, and with the Securities and Exchange Commission if
    applicable, no filing with, and no permit, authorization, consent or
    approval of, any state or federal public body or authority is necessary for
    the execution of this Stockholder Agreement by the Stockholder and the
    consummation by the Stockholder of the transactions contemplated hereby.
 
        8. The Stockholder's Shares (as listed on Schedule I) and the
    certificates representing such Shares are now and at all times during the
    term hereof will be held by the Stockholder, or by a nominee or custodian
    for the benefit of the Stockholder, free and clear of all liens, claims,
    security interests, rights of first refusal or offer, proxies, voting trusts
    or agreements, understandings or arrangements or any other encumbrances
    whatsoever, except for any such encumbrances or proxies arising hereunder.
 
        9. No broker, investment banker, financial advisor or other person is
    entitled to any broker's, finder's, financial advisor's or other similar fee
    or commission in connection with the transactions contemplated hereby based
    upon arrangements made by the Stockholder.
 
        10. The Stockholder agrees that damages are an inadequate remedy for the
    breach by the Stockholder of any term or condition of this Stockholder
    Agreement and that Acquiror shall be entitled, without limitation of other
    available rights or remedies, to specific performance, a temporary
    restraining order and preliminary and permanent injunctive relief in order
    to enforce the Stockholder's agreements herein.
 
        11. The Stockholder agrees that this Stockholder Agreement and the
    obligations hereunder shall attach to such Stockholder's Shares and shall be
    binding upon any person or entity to which legal or beneficial ownership of
    such Shares shall pass, whether by operation of law or otherwise, including
    without limitation such Stockholder's heirs, guardians, administrators or
    successors.
 
        12. From time to time, at the other party's request and without further
    consideration, each party hereto shall execute and deliver such additional
    documents and take all such further action as may be necessary or desirable
    to consummate and make effective, in the most expeditious manner
    practicable, the transactions contemplated by this Stockholder Agreement.
 
        13. This Stockholder Agreement may not be modified, amended, altered or
    supplemented, except upon the execution and delivery of a written agreement
    executed by the parties hereto.
 
                                      F-13
<PAGE>
        14. This Stockholder Agreement shall be governed by and construed in
    accordance with the laws of the State of Delaware, regardless of the laws
    that might otherwise govern under applicable principles of conflicts of laws
    thereof.
 
        15. Whenever possible, each provision or portion of any provision of
    this Stockholder Agreement will be interpreted in such manner as to be
    effective and valid under applicable law but if any provision or portion of
    any provision of this Stockholder Agreement is held to be invalid, illegal
    or unenforceable in any respect under any applicable law or rule in any
    jurisdiction, such invalidity, illegality or unenforceability will not
    affect any other provision or portion of any provision in such jurisdiction,
    and this Stockholder Agreement will be reformed, construed and enforced in
    such jurisdiction as if such invalid, illegal or unenforceable provision or
    portion of any provision had never been contained herein. Each party hereto
    irrevocably and unconditionally consents and submits to the exclusive
    jurisdiction of the courts of the State of Delaware and of the United States
    of America located in the State of Delaware for any actions, suits or
    proceedings arising out of or relating to this agreement and the
    transactions contemplated hereby, and further agrees that service of any
    process, summons, notice or document by U.S. registered or certified mail to
    the Stockholder at Duane Morris & Heckscher LLP, One Liberty Place,
    Philadelphia, PA 19103, Attention: Sheldon M. Bonovitz or Frederick W.
    Dreher, or to Acquiror c/o Bruckmann, Rosser & Sherrill & Co., Inc., 126
    East 56th Street, New York, N.Y. 10022, Attention: Bruce Bruckmann, shall be
    effective service of process for any action, suit or proceeding brought
    against such party in such court (and such address shall be also used for
    notices under this Stockholder Agreement). Each party hereto hereby
    irrevocably and unconditionally waives any objection to the laying of venue
    of any action, suit or proceeding arising out of this Stockholder Agreement
    or the transactions contemplated hereby, in the courts of the State of
    Delaware located in Wilmington, Delaware or the United States of America
    located in Wilmington, Delaware, and hereby further irrevocably and
    unconditionally waives and agrees not to plead or claim in any such court
    that any such action, suit or proceeding brought in any such court has been
    brought in an inconvenient forum.
 
        16. This Stockholder Agreement may be terminated at the option of any
    party at any time after the Termination Date (as defined in the Option
    Agreement). Please confirm that the foregoing correctly states the
    understanding between us by signing and returning to me a counterpart
    hereof, whereupon this will become a legal and binding obligation.

MQ Acquisition Corporation
c/o Bruckmann, Rosser & Sherrill & Co., Inc.
126 East 56th Street
New York, NY 10022
 
    Re: Stockholder Agreement
 
Dear Sirs:
 
    The undersigned (the "Stockholder") understands that MQ Acquisition
Corporation, a Delaware corporation ("Acquiror") and Mediq Incorporated, a
Delaware corporation (the "Company") are entering into an Agreement and Plan of
Merger, dated the date hereof, as the same may be amended from time to time (the
"Merger Agreement"), providing for, among other things, the merger of Acquiror
with and into the Company on the terms and conditions set forth therein (the
"Merger").
 
    The Stockholder is a stockholder of the Company and is entering into this
letter agreement (the "Stockholder Agreement") to induce you to enter into the
Merger Agreement and to consummate the transactions contemplated thereby.
Capitalized terms used but not defined herein shall have the same meanings as in
the Merger Agreement.
 
    The Stockholder confirms its agreement with you as follows:
 
        1. The Stockholder represents, warrants and agrees that Schedule I
    annexed hereto sets forth the Common Shares and Preferred Shares of which
    the Stockholder or its affiliates (as defined under the Securities Exchange
    Act of 1934, as amended) are the record or beneficial owner and that the
    Stockholder and its affiliates are on the date hereof the lawful owners of
    the number of Shares set forth in Schedule I beside the name of the
    Stockholder or such other person. Except as set forth in Schedule I, neither
    the Stockholder nor any of its affiliates, own or hold any rights to acquire
    any additional shares of the capital stock of the Company (by exercise of
    stock options or otherwise) or any interest therein or any voting rights
    with respect to any additional Shares. The Stockholder, together with other
    persons who are signatories to this Stockholder Agreement or letter
    agreements with Acquiror containing substantially the same terms and
    conditions as set forth herein, has sole voting power and sole power to
    issue instructions with respect to the matters set forth herein, sole power
    of disposition, sole power of conversion, sole power to demand appraisal
    rights and sole power to engage in the actions set forth herein, in each
    case with respect to the Shares set forth on Schedule I hereto beside the
    name of the Stockholder or such other person.
 
        2. The Stockholder agrees that it will not, will not permit any company,
    trust or other person or entity controlled by the Stockholder to, and will
    not permit any of its affiliates to, contract to sell, sell or otherwise
    transfer or dispose of any Shares or any interest therein or securities
    convertible therein to or any voting rights with respect thereto, other than
    (i) pursuant to the Merger, (ii) pursuant to the Option Agreement dated of
    even date herewith between Acquiror and the undersigned (iii) with your
    prior written consent. The Stockholder agrees that it shall not convert any
    Preferred Shares into Common Shares or take any other action which
    diminishes the benefits of this Stockholder Agreement to the Acquiror.
 
        3. The Stockholder agrees to, and to cause any company, trust or other
    person or entity controlled by the Stockholder to, cooperate fully with you
    in connection with the Merger Agreement, the Option Agreement, this
    Stockholders Agreement and the transactions contemplated thereby and hereby.
    The Stockholder agrees that it will not, and will not permit any such
    company, trust or other entity or person to, and will not authorize any of
    its affiliates to, directly or indirectly (including
 
                                      F-17
<PAGE>
    through its officers, directors, employees or other representatives) to
    solicit, initiate, encourage or facilitate, or furnish or disclose
    non-public information in furtherance of, any inquiries or the making of any
    proposal with respect to any recapitalization, merger, consolidation or
    other business combination involving the Company, or the acquisition of any
    capital stock or any material portion of the assets (except for acquisition
    of assets in the ordinary course of business consistent with past practice
    and not material in the aggregate to the Company) of the Company, or any
    combination of the foregoing (a "Competing Transaction"), or negotiate,
    explore or otherwise engage in discussions with any person (other than
    Acquiror and its affiliates, or their respective directors, officers,
    employees, agents and representatives) with respect to any Competing
    Transaction or enter into any agreement, arrangement or understanding with
    respect to any Competing Transaction or agree to or otherwise assist in the
    effectuation of any Competing Transaction; provided, however, that nothing
    herein shall require the Stockholder to prevent or restrict any director or
    trustee of the Stockholder who is a director or officer of the Company from
    taking any action in his capacity as a director or officer of the Company to
    the extent such director or officer would be permitted to take such action
    under the Merger Agreement.
 
        4. The Stockholder agrees that all of the Shares beneficially owned by
    the Stockholder, or over which the Stockholder has voting power or control,
    directly or indirectly (including any Shares beneficial ownership of which
    is acquired by the Stockholder after the date hereof), at the record date
    for any meeting of the Company's stockholders, however called, or in
    connection with any written consent of the stockholders of the Company,
    shall be voted (or caused to be voted) (i) in favor of the Merger, the
    execution and delivery by the Company of the Merger Agreement and the
    approval of the terms thereof and each of the other actions contemplated by
    the Merger Agreement, this Stockholder Agreement and the Option Agreement
    and any actions required in furtherance hereof and thereof; (ii) against any
    action or agreement that would result in a breach in any material respect of
    any covenant, representation or warranty or any other obligation of the
    Company under the Merger Agreement or under this Stockholder Agreement or
    the Option Agreement; and (iii) except as otherwise agreed to in writing in
    advance by Acquiror, against the following actions (other than the Merger
    and the transactions with you or your affiliates contemplated by the Merger
    Agreement): (1) any extraordinary corporate transaction, such as a merger,
    consolidation or other business combination involving the Company or its
    Subsidiaries; (2) any sale, lease or transfer of a material amount of assets
    of the Company or its Subsidiaries or a reorganization, recapitalization,
    dissolution or liquidation of the Company or its Subsidiaries; (3) (a)
    subject to Section 7 hereof, any change in the majority of the Board of
    Directors of the Company; (b) any material change in the present
    capitalization of the Company or any amendment of the Company's Certificate
    of Incorporation or Bylaws; (c) any other material change in the Company's
    corporate structure or business; or (d) any other action, which is intended,
    or could reasonably be expected, to impede, interfere with, delay, postpone,
    discourage or materially adversely affect the contemplated economic benefits
    to Acquiror of the Merger or the transactions contemplated by the Merger
    Agreement, this Stockholder Agreement or the Option Agreement. The
    Stockholder shall not enter into any agreement or understanding with any
    person or entity to vote or give instructions in any manner inconsistent
    with clauses (i), (ii) or (iii) of the preceding sentence.
 
        5. The Stockholder hereby grants to, and appoints, Acquiror and its
    officers, and any other designee of Acquiror, each of them individually, the
    Stockholder's irrevocable proxy and attorney-in-fact (with full power of
    substitution) to vote (as indicated in paragraph 4 above) the Shares listed
    on Schedule I hereto beside the name of the Stockholder, and any Shares
    beneficial ownership of which is acquired by the Stockholder after the date
    hereof, at a duly called meeting of the Company's stockholders (and, in the
    event the Stockholder has breached its obligations under this Stockholder
    Agreement or the Option Agreement or the Company breaches its obligation
    under the Merger Agreement to call and hold or otherwise fails to hold the
    Special Meeting, by duly executed written consent of stockholders). The
    Stockholder intends this proxy to be irrevocable, subject to Section 16
 
                                      F-18
<PAGE>
    hereof, and coupled with an interest and will take such further action and
    execute such other instruments as may be necessary to effectuate the intent
    of this proxy and hereby revokes any proxy previously granted by the
    Stockholder with respect to the Stockholder's Shares. The Stockholder agrees
    that if requested by Acquiror, the Stockholder will not attend or vote any
    Shares beneficially owned by the Stockholder at any annual or special
    meeting of stockholders or execute any written consent of stockholders.
 
        6. The Stockholder has the legal capacity, power and authority to enter
    into and perform all of such Stockholder's obligations under this
    Stockholder Agreement. The execution, delivery and performance of this
    Stockholder Agreement by such Stockholder will not violate any other
    agreement to which such Stockholder is a party including, without
    limitation, any trust agreement, voting agreement, stockholders agreement or
    voting trust. This Stockholder Agreement has been duly and validly executed
    and delivered by the Stockholder, and is enforceable against the Stockholder
    in accordance with its terms. There is no beneficiary or holder of any
    interest of the Stockholder or any trust of which the Stockholder is a
    trustee whose consent is required for the execution and delivery of this
    Stockholder Agreement or the consummation of the transactions contemplated
    hereby. If the Stockholder is married and the Stockholder's Shares
    constitute community property, this letter agreement has been duly
    authorized, executed and delivered by, and constitutes a valid and binding
    agreement of, the Stockholder's spouse, enforceable against such spouse in
    accordance with its terms.
 
        7. Except for filings under the Hart-Scott-Rodino Antitrust Improvements
    Act of 1976, as amended, and with the Securities and Exchange Commission if
    applicable, no filing with, and no permit, authorization, consent or
    approval of, any state or federal public body or authority is necessary for
    the execution of this Stockholder Agreement by the Stockholder and the
    consummation by the Stockholder of the transactions contemplated hereby.
 
        8. The Stockholder's Shares (as listed on Schedule I) and the
    certificates representing such Shares are now and at all times during the
    term hereof will be held by the Stockholder, or by a nominee or custodian
    for the benefit of the Stockholder, free and clear of all liens, claims,
    security interests, rights of first refusal or offer, proxies, voting trusts
    or agreements, understandings or arrangements or any other encumbrances
    whatsoever, except for any such encumbrances or proxies arising hereunder.
 
        9. No broker, investment banker, financial advisor or other person is
    entitled to any broker's, finder's, financial advisor's or other similar fee
    or commission in connection with the transactions contemplated hereby based
    upon arrangements made by the Stockholder.
 
        10. The Stockholder agrees that damages are an inadequate remedy for the
    breach by the Stockholder of any term or condition of this Stockholder
    Agreement and that Acquiror shall be entitled, without limitation of other
    available rights or remedies, to specific performance, a temporary
    restraining order and preliminary and permanent injunctive relief in order
    to enforce the Stockholder's agreements herein.
 
        11. The Stockholder agrees that this Stockholder Agreement and the
    obligations hereunder shall attach to such Stockholder's Shares and shall be
    binding upon any person or entity to which legal or beneficial ownership of
    such Shares shall pass, whether by operation of law or otherwise, including
    without limitation such Stockholder's heirs, guardians, administrators or
    successors.
 
        12. From time to time, at the other party's request and without further
    consideration, each party hereto shall execute and deliver such additional
    documents and take all such further action as may be necessary or desirable
    to consummate and make effective, in the most expeditious manner
    practicable, the transactions contemplated by this Stockholder Agreement.
 
        13. This Stockholder Agreement may not be modified, amended, altered or
    supplemented, except upon the execution and delivery of a written agreement
    executed by the parties hereto.
 
                                      F-19
<PAGE>
        14. This Stockholder Agreement shall be governed by and construed in
    accordance with the laws of the State of Delaware, regardless of the laws
    that might otherwise govern under applicable principles of conflicts of laws
    thereof.
 
        15. Whenever possible, each provision or portion of any provision of
    this Stockholder Agreement will be interpreted in such manner as to be
    effective and valid under applicable law but if any provision or portion of
    any provision of this Stockholder Agreement is held to be invalid, illegal
    or unenforceable in any respect under any applicable law or rule in any
    jurisdiction, such invalidity, illegality or unenforceability will not
    affect any other provision or portion of any provision in such jurisdiction,
    and this Stockholder Agreement will be reformed, construed and enforced in
    such jurisdiction as if such invalid, illegal or unenforceable provision or
    portion of any provision had never been contained herein. Each party hereto
    irrevocably and unconditionally consents and submits to the exclusive
    jurisdiction of the courts of the State of Delaware and of the United States
    of America located in the State of Delaware for any actions, suits or
    proceedings arising out of or relating to this agreement and the
    transactions contemplated hereby, and further agrees that service of any
    process, summons, notice or document by U.S. registered or certified mail to
    the Stockholder at Duane Morris & Heckscher LLP, One Liberty Place,
    Philadelphia, PA 19103, Attention: Sheldon M. Bonovitz or Frederick W.
    Dreher, or to Acquiror c/o Bruckmann, Rosser & Sherrill & Co., Inc., 126
    East 56th Street, New York, N.Y. 10022, Attention: Bruce Bruckmann, shall be
    effective service of process for any action, suit or proceeding brought
    against such party in such court (and such address shall be also used for
    notices under this Stockholder Agreement). Each party hereto hereby
    irrevocably and unconditionally waives any objection to the laying of venue
    of any action, suit or proceeding arising out of this Stockholder Agreement
    or the transactions contemplated hereby, in the courts of the State of
    Delaware located in Wilmington, Delaware or the United States of America
    located in Wilmington, Delaware, and hereby further irrevocably and
    unconditionally waives and agrees not to plead or claim in any such court
    that any such action, suit or proceeding brought in any such court has been
    brought in an inconvenient forum.
 
        16. This Stockholder Agreement may be terminated at the option of any
    party at any time after the Termination Date (as defined in the Option
    Agreement). Please confirm that the foregoing correctly states the
    understanding between us by signing and returning to me a counterpart
    hereof, whereupon this will become a legal and binding obligation.

                                   AGREEMENT
 
    THIS AGREEMENT (the "Agreement") is dated as of January 14, 1998 by and
between MQ Acquisition Corporation, a Delaware corporation ("MQ"), MEDIQ
Incorporated, a Delaware corporation ("MEDIQ"), Michael J. Rotko ("Rotko"), T/D
Bernard B. Rotko dated November 18, 1983 (the "Rotko Trust), Bessie G. Rotko and
Judith M. Shipon (each a "Rotko Entity," and collectively with Rotko, the "Rotko
Entities").
 
BACKGROUND
 
    Contemporaneously with the execution of that certain Agreement and Plan of
Merger, dated as of January 14, 1998 (as may be amended from time to time, the
"Merger Agreement") by and between MQ and MEDIQ, MQ requires that Rotko Entities
enter into this Agreement whereby the Rotko Entities agree to convert an
aggregate of 1,000,000 shares (the "Rolled Shares") of Series A Preferred Stock,
par value $.50 per share of MEDIQ (the "MEDIQ Preferred Stock") into certain
securities specified herein.
 
    Capitalized terms used herein but not otherwise defined shall have the
meanings ascribed to them in the Merger Agreement.
 
    NOW, THEREFORE, in consideration of the premises and the agreements
contained herein and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto agree as
follows:
 
           1.  ROLLOVER.  The parties hereto agree that either (i) immediately
       prior to the Effective Time, the Rotko Entities will transfer the Rolled
       Shares to MQ (the "Contribution") in exchange for securities of MQ, which
       at the Effective Time will be converted into 1,340,200 shares of Series B
       Preferred Stock (defined below) and a number of shares of Common Stock of
       the Surviving Corporation equal to 10.98% (assuming an initial investment
       of $10 million of Common Stock) of the total outstanding shares of Common
       Stock of the Surviving Corporation (the Series B Preferred Stock and the
       Common Stock, together the "Converted Shares") or (ii) the Certificate of
       Merger that is to be filed pursuant to Section 1.2 of the Merger
       Agreement shall provide that the Rolled Shares shall be converted into
       the Converted Shares. The decisions as to whether alternative (i) or (ii)
       above be employed shall be determined by MQ in its sole discretion with
       the approval of MEDIQ, such approval not to be unreasonably withheld. For
       purposes of this Agreement, "Series B Preferred Stock" shall mean
       preferred stock of the Surviving Corporation having the terms
       substantially in the form attached hereto as EXHIBIT I.
 
           2.  ALLOCATION.  The Rolled Shares to be converted into the Converted
       Shares pursuant to paragraph 1 shall be determined, and the Converted
       Shares shall be distributed to the each of the Rotko Entities, based on
       their pro rata ownership of Preferred Stock as set forth on Schedule I
       hereto; PROVIDED, that the Rotko Trust may, prior to the fifth business
       day prior to the Effective Time, notify MQ in writing of a revised
       allocation of Rolled Shares among the Rotko Entities and the allocation
       of the Converted Shares among the Rotko Entities, whereby such Schedule I
       shall be revised to reflect such revised allocation (so long as the
       aggregate number of Rolled Shares converted into the aggregate number of
       Converted Shares and the aggregate number of Converted Shares distributed
       in respect of the Rolled Shares remains unchanged) (the "Reallocation");
       PROVIDED FURTHER that the Reallocation shall not adversely affect the
       accounting treatment or the economic impact of the Merger and related
       transactions to MQ, the Surviving Corporation and their shareholders
       other than the Rotko Entities.
 
                                      G-1
<PAGE>
           3.  REPRESENTATIONS AND WARRANTIES OF THE ROTKO ENTITIES.  Each of
       the Rotko Entities represents and warrants that (i) the Rotko Entities as
       the sole beneficial owner of the Rolled Shares and have good title to,
       the Rolled Shares, free and clear of any lien, security interest,
       restriction, right of first refusal or encumbrance or claim of any kind,
       (ii) at the Effective Time, the Rotko Entities will be the sole
       beneficial owner of the Rolled Shares and will have good title to, the
       Rolled Shares, free and clear of any lien, security interest,
       restriction, right of first refusal or encumbrance or claim of any kind,
       (iii) this Agreement has been duly executed and delivered by each of the
       Rotko Entities, and this Agreement constitutes the legal, valid and
       binding obligations of each of the Rotko Entities, enforceable in
       accordance with its terms, and (iv) each of the Rotko Entities has full
       legal right, power and authority to enter into this Agreement and to
       perform its other obligations hereunder.
 
           4.  TERMINATION.  This Agreement shall terminate immediately upon the
       termination of the Merger Agreement if the Merger Agreement is terminated
       prior to the Effective Time; provided, that if the termination of the
       Merger Agreement results from a failure of the condition set forth in
       Section 5.12(c) thereof to be satisfied, such termination shall not
       derogate from MQ's rights under this Agreement. The obligations of the
       parties hereto under this Agreement are subject to the execution of a
       definitive shareholders agreement (the "Shareholders Agreement")
       reasonably satisfactory to the parties embodying terms substantially as
       set forth in Exhibit I. .
 
           5.  COUNTERPARTS.  This Agreement may be executed in identical
       counterpart copies, each of which shall be an original, but all of which
       taken together shall constitute one and the same agreement.
 
           6.  FURTHER ASSURANCES.  The parties hereto agree to execute such
       other documents and to take such further actions as may be necessary to
       carry out the intent and purposes of this Agreement and the transactions
       contemplated hereby.
 
           7.  FACSIMILES.  This Agreement and any signed agreement or
       instrument entered into in connection with this Agreement, and any
       amendments hereto or thereto, to the extent signed and delivered by means
       of a facsimile machine, shall be treated in all manner and respects as an
       original agreement or instrument and shall be considered to have the same
       binding effect as if it were the original signed version thereof
       delivered in person. At the request of any party hereto or to any such
       agreement or instrument, each other party hereto or thereto shall
       re-execute original forms thereof and deliver them to all other parties.
       No party hereto or to any such agreement or instrument shall raise the
       use of a facsimile machine to deliver a signature or the fact that any
       signature or agreement or instrument was transmitted or communicated
       through the use of a facsimile machine as a defense to the formation of a
       contract and each such party forever waives any such defense.
 
           8.  GOVERNING LAW.  THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED
       IN ACCORDANCE WITH THE LAWS OF THE STATE OF DELAWARE WITHOUT REGARD TO
       THE CONFLICTS OF LAW PRINCIPLES THEREOF.
 
                                      G-2

    IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of
the date and year first written above.

     the following:
 
     -- If BRS sells (other than to affiliates, coinvestors and other similar
        parties) or has redeemed more than 10% of its original investment in
        Series B Preferred Stock, the Rotko Entities will have the right to
        participate on same terms and conditions pro rata with BRS and other
        holders of Series B Preferred Stock; provided, that if such sale or
        redemption is to or by the Company or any person related to the Company
        within the meaning of Section 351(g)(3)(B) of the Internal Revenue Code
        (the Company and such a related person referred to herein as a
        "Disqualified Person"), then BRS and/or its coinvestors, their
        respective affiliates or a third party designated by BRS (other than a
        Disqualified Person) will offer to purchase such shares in lieu of the
        Disqualified Person and any such purchase shall not be directly or
        indirectly funded by a Disqualified Person.
 
     -- If holders of a majority of Series B Preferred Stock proposes to sell
        their shares, they may elect to drag along the Rotko Entities who will
        consent to, and waive any objections with respect to, such transaction;
        PROVIDED, that, if such sale is to a Disqualified Person, BRS and/or its
        coinvestors, their respective affiliates or a third party designated by
        BRS (other than a Disqualified Person) shall have the right to purchase
        such shares in lieu of the Disqualified Person and any such purchase
        shall not be directly or indirectly funded by a Disqualified Person.
 
     -- If the Company shall redeem shares of the Series A or Series C Preferred
        Stock, BRS and/or its coinvestors, their respective affiliates or a
        third party designated by BRS (other than a Disqualified Person) will
        offer to purchase (the "Purchase Option") from the Rotko Entities a
        percentage of the Series B Preferred Stock held by them equal to the
        aggregate liquidation preference of the Series A or Series C Preferred
        Stock so redeemed (not including any redemption of Series A
 
                                      G-4
<PAGE>
        Preferred Stock issued as Merger Consideration) divided by the sum of
        the aggregate liquidation preference of the Series A, B and C Preferred
        Stock then outstanding plus the original cost of the shares of Common
        Stock then outstanding; it being understood that (i) the intent of the
        foregoing provision is to provide the Rotko Entity with a similar
        investment opportunity as if they converted on the same terms as BRS and
        its coinvestors and acquired Shares of Series A, B and C Preferred Stock
        and Common Stock in the same proportions as BRS and other coinvestors,
        (ii) a purchase pursuant to the Purchase Option shall not be directly or
        indirectly funded by a Disqualified Person and (iii) the purchase price
        pursuant to the Purchase Option for the Series B Preferred Stock shall
        be in an amount not less than the par value plus accrued dividends on
        such stock and shall be paid in comparable consideration to that offered
        to the redeeming shareholders.
 
 12. PREEMPTION: The Shareholders Agreement will provide that, if the Company
     proposes to sell any equity securities, then the holders of the Series B
     Preferred Stock will have an opportunity to purchase a proportionate amount
     of such equity securities on the same terms and conditions as offered by
     the Company (in the ratio of their equity ownership in the Company over the
     total equity in the Company prior to the sale), unless such equity
     securities are issued (A) in connection with a business combination
     (unanimously approved by Company's Board of Directors), (B) to the
     Company's management or directors, (C) in connection with debt financing or
     a bona fide public offering or (D) subject to certain other exceptions to
     be negotiated.
 
 13. RESTRICTIONS ON TRANSFER. For the five year period beginning the Effective
     Time, the Rotko Entities will not be permitted to transfer their Series B
     Preferred Stock or their Common Stock other than to family members and
     others by the law of descent distribution or trusts for the benefit of such
     persons. For the five year period beginning on the fifth anniversary of the
     Effective Time and ending on the tenth anniversary of the Effective Time,
     the Rotko Entities may transfer their shares of Series B Preferred and
     Common stock subject to the restrictions applicable to such shares. After
     the tenth anniversary of the Effective Time, the Rotko Entities may
     transfer their shares of Series B Preferred and Common stock free of the
     restrictions applicable to such shares.
 
 14. BOARD OF DIRECTORS: The Shareholder Agreement will provide that the Rotko
     Trust shall have the right to elect one director of the Company so long as
     the Rotko Entities own 5% or more of the Common Stock of the Company.
 
 15. TAG-ALONG/DRAG-ALONG RELATING TO COMMON SHARES: The Shareholders Agreement
     will provide that if BRS proposes to sell 10% or more of its Common Shares
     to a third party, then the Rotko Entities will have the right to
     participate on the same terms and conditions pro rata with BRS and other
     holders of the Common Stock subject to certain exceptions to be negotiated.
     The Shareholders Agreement will provide that if the holders of a majority
     of the Common Shares proposes to sell their shares to a third party, they
     may elect to drag along the Rotko Entities on the same terms and conditions
     who will consent to, and waive any objections with respect to, such
     transaction. The tag-along and drag-along rights relating to the Common
     Stock will terminate immediately prior to such time as there is a bona fide
     public offering of the Company's Common Stock.
 
 16. PIGGY-BACK RIGHTS. The Rotko Entities may include their shares of the
     Series A Preferred Stock or Series B Preferred Stock, on a pro rata basis
     with other shareholders, in any registration statement filed by the Company
     under the Securities Act of 1933 (other than with respect to Form S-4 and
     Form S-8) that registers shares of Series A Preferred Stock or Series B
     Preferred Stock on terms and conditions to be negotiated.
