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

                                    the conversion of any shares of MEDIQ Preferred Stock

                                    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
                                    each has agreed, subject to certain limitations, that
                                    all of the MEDIQ Stock beneficially owned by each 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 transaction 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, with the result that
                                    following the Merger stockholders' equity will decline
                                    from its present level to a deficit of $322 million on a
                                    pro forma basis as if such transaction had occurred on
                                    September 30, 1997 and negatively affect the Company's
                                    earnings due to substantially increased interest costs
                                    (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 may also be limited
                                    by the terms of the financing arrangements the Company
                                    will enter into as part of the Merger. See "RISK
                                    FACTORS."

                                    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.

                                    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

                                    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

Solicitation of Proxies...........  The cost of soliciting Proxies will be borne by the
                                    Company. The Company may solicit Proxies and the

                                    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

                                    Common Stock and each issued and outstanding share of
                                    MEDIQ Preferred Stock will be converted into the right

                                    directly or indirectly by MQ or the Company 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. As a result of the transactions contemplated by
                                    the Merger Agreement, the only equity interest in the

                                    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

                                    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"), the effectiveness of the
                                    Registration Statement, the dissemination of this Proxy
                                    Statement/Prospectus and the Schedule 13E-3 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 to the continuing truth
                                    in all material respects of the Company's

                                    litigation intended to prevent the Merger and the
                                    receipt of proceeds of the financings described in the
                                    commitment letters MQ has received from financial
                                    institutions with respect to the funds necessary to
                                    consummate the transactions contemplated by the Merger
                                    Agreement on 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) in amounts sufficient to consummate the
                                    transactions contemplated by the Merger Agreement, the
                                    Rotko Entities' performance of their obligations under

                                    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

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 below). Under certain
                                    circumstances related to a third party transaction,
                                    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--Termination" and "--No Solicitation of
                                    Alternative 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 and the Antitrust Division
                                    of the Department of Justice (the "Antitrust Division")
                                    in respect of the Merger and the related transactions.
                                    Prior to the Merger, the relevant waiting period under
                                    the HSR Act with respect to the Merger must be
                                    terminated or expire. 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

                                    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. 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

                                    Merger Agreement. For a summary of the foregoing

                                    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

                                    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 shall not have been previously
                                    exercised, it shall 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

THE ROLLOVER AGREEMENT............  As a condition to entering into the Merger Agreement, MQ
                                    required that the Rotko Entities enter into the Rollover
                                    Agreement. Pursuant to the Rollover Agreement, the Rotko
                                    Entities have agreed to convert the Rolled Shares into
                                    certain securities specified therein. The parties to the
                                    Rollover Agreement have agreed that either (i)
                                    immediately prior to the Effective Time, the Rotko
                                    Entities will transfer the Rolled Shares to MQ in
                                    exchange for securities of MQ which, at the Effective
                                    Time, will be converted into 1,340,200 shares of Series
                                    B Preferred Stock of the Surviving Corporation (the
                                    "Series B Preferred Stock") and a number of shares of
                                    Common Stock of the Surviving Corporation equal to
                                    10.98% (assuming an initial investment of $10.0 million
                                    in such common stock by the stockholders of the
                                    Surviving Corporation) of the shares of Common Stock of
                                    the Surviving Corporation to be outstanding immediately
                                    after the Effective Time (such Series B Preferred Stock
                                    and Common Stock of the Surviving Corporation are from
                                    time to time referred to herein together as the
                                    "Converted Shares") or (ii) the Certificate of Merger
                                    that is to be filed pursuant to the Merger Agreement
                                    will provide that the Rolled Shares will be converted in
                                    the Merger into the Converted Shares. 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, however, that if the termination of the Merger
                                    Agreement results from a failure to satisfy a condition
                                    relating to the performance by the Rotko Entities of the
                                    Rollover Agreement, such termination will not derogate
                                    from MQ's rights under the Rollover Agreement. For a
                                    summary of the foregoing provisions and certain other

Notes to Selected Consolidated 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 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.
 
(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 included in the computation of any diluted per
    share amount. Accordingly, only basic earnings per share have been
    presented.
 
(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
 
                                       17
<PAGE>
    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.

                                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 January 1995, the Company formed a special committee of the Board of
Directors and retained a financial advisor for the purpose of exploring
alternative ways to maximize stockholder value, including the possible sale or
restructuring of the Company. During this process, 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, including an offer from certain of the then current members of the
Company's management to acquire all of the MEDIQ Stock outstanding at that time
for $6.87 per share, consisting of $4.00 in cash and a pro rata interest in a
liquidating trust with an estimated value of $2.87 per share. In April 1995, the
Board accepted the recommendation of the special committee to reject that offer
as inadequate. In April, 1995, Mr. Carroll was elected President and Chief
Executive Officer of the Company. At that time, 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 a sale of the Company. See "SPECIAL FACTORS--Interests of
Certain Persons in the Merger." The Company and its financial advisor continued
to work through the spring and summer of 1995 to attract offers to acquire the
Company, but did not receive any satisfactory proposals. Finally, after
exploring a number of alternatives with its financial advisor, in October 1995,
the Board accepted the recommendation of the special committee to terminate any
further efforts to sell the Company at that time. The Board determined instead
to continue its previously announced strategy of divesting non-core operating
assets and using the divestiture proceeds to reduce indebtedness. This asset
sale 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 Products,
Inc. ("NutraMax") pursuant to which NutraMax agreed to repurchase all of the
NutraMax shares 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 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 substantially complete, 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 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 Hart-Scott-Rodino Antitrust Improvements
Act. In July 1997, the Company and UHS were informed by the Federal Trade
Commission (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. 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.
 
                                       20
<PAGE>
    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 submitted the six highest indications of interest,
five of which were from 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 conclusions reached by the
Executive Committee at its meeting on November 21.
 
    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.
 
    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 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 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
 
                                       21
<PAGE>
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 significantly lower price than the cash portion of the BRS
proposal. The Board, after conferring with executive management and the
Company's legal and financial advisors, determined that the substantially lower
bid, as well as other aspects of the third bidder's proposal, made it
undesirable 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.
 
    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.
 
                                       22
<PAGE>
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.
Because the value of the cash-only alternative was estimated to be approximately
$0.25 per share less than the combined cash and stock proposal, 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 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 the firm of Duane, Morris & Heckscher LLP on behalf
of the Rotko Entities, separately negotiated with BRS the
 
                                       23
<PAGE>
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 acquire securities of the Surviving Corporation at the same price at which
BRS would acquire securities of the same class and/or series in the Merger.
 
    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.
 
    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 Equity Contribution 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 Investor 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
 
                                       24
<PAGE>
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 Investor 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 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
 
                                       25
<PAGE>
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 value of the
      Merger Consideration of approximately $14.25 per share was more than was
      offered by the next highest bidder;
 
    - 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 and approximately 27% over
      the closing price of $10.8125 per share of the MEDIQ Preferred Stock on
      January 13, 1998, and approximately 62% over the closing price of $8.50
      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 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 was conducted in an evenhanded manner and that
      third parties interested in the Company had been afforded sufficient time
      and information to submit such a proposal had they wished to do so;
 
    - 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;
 
    - 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;
 
                                       26
<PAGE>
    - 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, for the foregoing
      reasons, 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 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
making an investment in the Company. MQ elected to proceed with the Merger for
the same purpose that motivated BRS. MQ and BRS believe that the Company will
have greater operating flexibility to focus on its long-term value by
emphasizing growth and operating cash flow without the constraint of the public
market's emphasis on quarterly earnings.
 
POSITION OF BRS AND MQ AS TO FAIRNESS OF THE MERGER
 
    BRS and MQ have considered the analyses of and the 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"), and BRS
and MQ believe these analyses and factors, when considered together with the
establishment of the Special Committee, the opinion of Salomon Smith Barney (see
"--Opinion of the Company's Financial Advisor") and the arm's length nature of
the negotiations between BRS and MQ, on the one hand, and the Company, on the
other, 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.

PURPOSES AND REASONS OF THE ROTKO ENTITIES AND MR. CARROLL 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
Mr. Carroll in agreeing to the transactions contemplated by the Merger Agreement
are to continue the pursuit of his 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 MR. CARROLL AS TO FAIRNESS OF THE MERGER
 
    Neither the Rotko Entities nor Mr. Carroll 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. Based, however, on their consideration
of, among other things, (i) historical market prices for the MEDIQ Stock
(including the fact that the Merger Consideration of approximately $14.25 per
share of MEDIQ Stock (valuing .075 of a share of Series A Preferred Stock at
approximately $0.50) is substantially higher than the market price per share of
MEDIQ Common Stock and MEDIQ Preferred Stock on the last full day on which each
such class of stock traded prior to announcement that the Company and MQ had
entered into the Merger Agreement), and (ii) the factors taken into account by
the Special Committee and the Board of Directors, including that an auction
process was conducted on behalf of the Company and that the Board of Directors
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, each of the Rotko Entities and Mr. Carroll believes that the Merger is
fair to the stockholders of the Company.
 
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. The Rotko Entities will also be required to acquire shares of the
Company's 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. MQ, BRS and the Rotko
Entities have also agreed to enter into a
 
                                       28
<PAGE>
securities 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 certain "drag-along," "tag-along,"
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 elect one
director of the Company so long as the Rotko Entities collectively own 5% or
more of the Surviving Corporation Common Stock. 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 upon the purchase price paid for the Company and, in the case
of Mr. Sandler, 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 $[ ] 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. Mr. Carroll is also
entitled to be indemnified by the Company for certain expenses incurred in
connection with his employment by the Company.
 
    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 $[   ] 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 a "Sale Event" (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 a "Sale Event." 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
 
                                       29
<PAGE>
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 $[      ] 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
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 will use the
after-tax proceeds from approximately $9.5 million in value received in respect
of the Option Consideration (the "Net Proceeds") to purchase securities of MQ
which will be converted into 7.7% of the Common Stock of the Surviving
Corporation upon consummation of the Merger at an aggregate purchase price of
$719,364, with the remaining Net Proceeds of approximately $         used to
purchase securities of MQ which will be converted into Series A Preferred Stock,
Series B Preferred Stock and Series C Preferred Stock of the Surviving
Corporation (the "Series C Preferred Stock" and, collectively with the Series A
Preferred Stock and the Series B Preferred Stock, the "Surviving Corporation
Preferred Stock"). The Surviving Corporation Preferred Stock will be acquired by
the Management Stockholders as described in "CAPITALIZATION."
 
    Immediately after the Effective Time and in connection with the Merger, the
Management Stockholders and others will also have the opportunity to purchase up
to 7.5% of the Surviving Corporation Common Stock at an aggregate purchase price
of $833,333. The Surviving Corporation Common Stock so acquired (the "Management
Purchase Shares") will, as to an individual Management Stockholder, 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 Management Stockholder 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
Management Stockholder resigns, 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, the Management
Stockholders and others will also have the opportunity to receive non-qualified
options (the "New Options") to purchase shares of Surviving Corporation Common
Stock equal to an aggregate of 2.5% of the outstanding Surviving Corporation
Common Stock at an aggregate exercise price of $277,777. Each year during such
five-year period, the Management Stockholders will have the opportunity to
acquire New Options for 0.5% of the
 
                                       30
<PAGE>
outstanding Surviving Corporation Common Stock. For each year, the opportunity
to receive any New Option will be subject to the Surviving Corporation's
achievement of certain financial performance conditions. In certain
circumstances, the Management Stockholders will have the right to immediately
receive any unissued or unvested New Options regardless of whether certain
financial performance conditions have been met. See "THE MERGER--Option
Consideration".
 
    OTHER.  Consummation of the Merger will also trigger certain rights to
receive distributions from the Company's deferred compensation plan.
 
    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 the Company (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 the Surviving
Corporation. In addition, BRS, or an affiliate of BRS, will receive a
transaction fee in respect of the Transactions.
 
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 Internal Revenue Code of 1986, as amended ("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.
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, tax-exempt entities and persons who do not hold their
shares as capital assets. 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 AND EXPECTED 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% 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
 
                                       31
<PAGE>
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
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
 
                                       32
<PAGE>
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).
 
                                       33
<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
 
                                       34
<PAGE>
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 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 II 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 IS QUALIFIED IN ITS ENTIRETY
BY REFERENCE TO THE FULL TEXT 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
 
                                       35
<PAGE>
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 performance, general business, economic, market and financial
conditions and other matters, many of which are beyond the control of the
Company and MQ. 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
 
                                       36
<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
 
                                       37
<PAGE>
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

FORECASTS; LIMITS OF RELIABILITY
 
    The Company does not as a matter of policy make public forecasts or
projections as to future performance or earnings. 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.

<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 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 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 an acquisition program by the Company and the
occurrence of certain other events (the "Acquisition Projections"). The
Acquisition Projections reflected the projected effects of potential
acquisitions not included in the Management Projections, the expansion of the
Company's business internationally and the expansion of the Company's
relationship with an existing business partner. 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. As of the date hereof, none of the acquisitions included in the
Acquisition Projections have been consummated or are probable and the Company
has not implemented any international expansion plans. 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 $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 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 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
 
                                       39
<PAGE>
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

                                  RISK FACTORS
 
SUBSTANTIAL LEVERAGE; STOCKHOLDERS' DEFICIT; LIQUIDITY
 
    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 refinance a
portion of indebtedness of the Company, to pay a portion of the fees and
expenses incurred in connection with the Merger and the Financings and to
provide for working capital requirements. Although the definitive terms of these
debt instruments have not been finalized as of the date of this Proxy Statement/
Prospectus, the Company expects that such terms will include significant
operating and financial restrictions, including limits on the Company's ability
to incur indebtedness, create liens, sell assets, engage in mergers or
consolidations, make investments and capital expenditures and pay dividends.
Upon consummation of the Merger, it is expected that the Company will have
substantial consolidated indebtedness. As of September 30, 1997, after giving
pro forma effect to the Merger and the Financings and the application of the net
proceeds therefrom, (i) the Company would have had $418.7 million of
consolidated indebtedness and (ii) since 370.7 million will be charged to
stockholders' equity, a deficit of $322.1 million in stockholders' equity would
exist. See "PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS." In addition,
the Company expects to incur additional indebtedness in connection with its
post-Merger strategy of pursuing strategic acquisitions and expanding through
internal growth. See "THE COMPANY." Such increased indebtedness and the
resulting leverage may have important consequences for the Company, including
the following: (i) the Company's ability to obtain additional financing for
acquisitions, working capital, capital expenditures or other purposes may be
impaired and any such financing may not be on terms favorable to the Company;
(ii) interest expense may reduce the funds that otherwise would be available to
the Company for its operations and future business opportunities; (iii) a
substantial decrease in net operating cash flows or an increase in expenses of
the Company could make it difficult for the Company to meet its debt service
requirements or pay cash dividends on the Series A Preferred Stock, and may
require the Company to modify its operations; (iv) substantial leverage may
place the Company at a competitive disadvantage and may make it more vulnerable
to a downturn in its business or the economy generally; (v) certain of such
indebtedness of the Company will be at variable rates of interest, which would
cause the Company to be vulnerable to increases in interest rates; (vi) certain
of such indebtedness will be secured by substantially all the assets of the
Company, reducing its ability to obtain additional financing; and (vii) the
Company may be hindered in the Company's ability to adjust rapidly to changing
market conditions. See "SOURCES AND AMOUNT OF FUNDS."
 
    In addition, the substantial leverage will have a negative effect on the
Company's net income. For the fiscal year ended September 30, 1997, the
Company's loss from continuing operations, on a pro forma basis as adjusted to
give effect to the Transactions and the acquisition of SpectraCair, but
excluding non-recurring items directly attributable to the Merger, would have
been $15.3 million, compared to the historical amounts for such period of $2.2
million. Pro forma net interest expense would have been $38.3 million (net of
$2.1 million of interest income) for the year ended September 30, 1997, as
compared to $17.0 million (net of $2.1 million of interest income) for the same
period on a historical basis. See "PRO FORMA CONDENSED CONSOLIDATED FINANCIAL
STATEMENTS."
 
    At the Effective Time, MEDIQ/PRN is expected to enter a new senior secured
credit facility consisting of a $175.0 million senior secured term loan facility
and a $50.0 million senior secured working capital credit facility. The new
credit facility agreement is expected to include certain covenants that, among
other things, restrict: (i) the making of investments, loans and advances,
redemptions and repurchases of capital stock and the paying of dividends and
other restricted payments including dividends in respect of the Series A
Preferred Stock to be issued in the Merger; (ii) the incurrence of additional
indebtedness; (iii) the granting of liens, other than certain permitted liens;
(iv) mergers, consolidations, and sales of all or a substantial part of the
Company's business or property; (v) the sale of assets; and
 
                                       41
<PAGE>
(vi) the making of capital expenditures. The Company will also be required to
maintain certain financial ratios, including interest coverage, fixed charge
coverage and leverage ratios. All of these restrictive covenants may restrict
the Company's ability to expand or to pursue its business strategies. The
ability of the Company to comply with these and other provisions of the new
credit facility agreement may be affected by changes in economic or business
conditions, results of operations or other events beyond the Company's control.
The breach of any of these covenants could result in a default under the new
credit facility agreement, in which case, depending on the actions taken by the
lenders thereunder or their successors or assignees, such lenders could elect to
declare all amounts borrowed under the new credit facility, together with
accrued interest, to be due and payable, and the Company could be prohibited
from making payments with respect to other indebtedness or in respect of the
Series A Preferred Stock until the default is cured or all indebtedness under
the new credit facility is paid or satisfied in full. If the Company were unable
to repay such borrowings, such lenders could proceed against their collateral.
If the indebtedness under the new credit facility were to be accelerated, there
can be no assurance that the assets of the Company would be sufficient to repay
in full such indebtedness and the other indebtedness of the Company.
 
    After the Merger is consummated, the Company's principal sources of
liquidity are expected to be cash flows from operations and borrowings under the
working capital credit portion of its senior secured credit facility. It is
anticipated that the Company's principal uses of liquidity under the new working
capital credit facility will be to finance working capital, meet debt service
requirements and make capital expenditures, and a portion thereof will be
available for the issuance of letters of credit. The term loan portion of the
senior secured credit facility will be drawn in full upon consummation of the
Merger.
 
CONTROL OF THE COMPANY
 
    Upon consummation of the Merger, a majority of the outstanding shares of
each class of capital stock of the Company will be held by the Investors.
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.
 
    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.
 
    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 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.
 
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
 
                                       42
<PAGE>
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 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.
 
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. 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
 
                                       43
<PAGE>
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; Stockholders' Deficit; Liquidity"
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 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, 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 (as defined in "SOURCES AND AMOUNT OF FUNDS"),
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.

                              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 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--Control 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 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. The
Merger Agreement (including the principal exhibits thereto) is attached to this
Proxy Statement/Prospectus as Annex I. See "THE MERGER" and "CERTAIN PROVISIONS
OF THE MERGER AGREEMENT." The Special Committee and the Board of Directors of
the Company have each, by unanimous vote, 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.       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       shares of MEDIQ
Preferred Stock, being a majority of the shares of MEDIQ Preferred Stock
entitled to vote thereon, are required to adopt and approve the Merger Agreement
and the transactions contemplated thereby, including the Merger.
 
    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), 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 going effect to the exercise of any outstanding
 
                                       45
<PAGE>
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. 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           , 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       shares of MEDIQ Common Stock and
      shares of MEDIQ Preferred Stock. The approximate number of record holders
of MEDIQ Shares on the Record Date is     . 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 the holders
at least       shares of MEDIQ Common Stock and       shares of MEDIQ Preferred
Stock, is necessary to constitute a quorum for the 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.

<PAGE>
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."

extent permissible) of the conditions set forth in the Merger Agreement (see
"THE MERGER--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 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 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."
 
                                       48
<PAGE>
EXCHANGE OF SHARES
 
    [          ] or another bank or trust company designated by MQ will 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 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 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 Preferred Stock (the "Excess Shares") representing such
fractions. Such sale will be made as soon as practicable after the Effective
Time.

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

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, MQ has agreed
that 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 of the Surviving Corporation 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 and generally including, without limitation, directors,
certain executive officers and beneficial owners of 10% or more of a class of
voting capital stock) 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.

                          SOURCES AND AMOUNT OF FUNDS
 
    It is expected that the funds required to consummate the Merger and the
Refinancing and to pay related fees and expenses will be provided by (i) $108.1
million of gross proceeds from the Investor Equity Contribution, (ii) $5.7
million of gross proceeds from the Management Equity Contribution, (iii) the
issuance of approximately $20.0 million of Series A Preferred Stock in
connection with the conversion of each issued and outstanding MEDIQ Share (other

Company) into the Merger Consideration, (iv) the issuance of $14.5 million of
equity pursuant to the Rollover, (v) $175.0 million from the Term Loans, (vi)

(vii) $30.0 million of gross proceeds from the Discount Debenture Offering,
(viii) $3.6 million in existing cash of the Company, and (ix) $.3 million of
borrowings under the revolving credit facility.
 
    The documentation governing the New Credit Facility, the Senior Subordinated
Notes (as defined), and the Discount Debentures (as defined) have not yet been
finalized. The following summary (i) is based upon certain commitment letters
provided to Bruckmann, Rosser, Sherrill & Co., Inc. (the "Sponsor"), (ii)
assumes that the Company becomes a party to such letters on or prior to the
consummation of the Merger and (iii) is subject to completion of final
documentation.
 
DESCRIPTION OF NEW CREDIT FACILITY
 
    The Company's existing $260.0 million credit facility (the "Existing Credit
Facility") with a syndicate of banks led by Banque Nationale de Paris ("BNP")
will be replaced by a senior secured credit facility provided to MEDIQ/PRN in an
aggregate principal amount of $225 million (the "New Credit Facility"). Pursuant
to the Senior Secured Credit Facility Commitment Letter dated as of February 2,
1998 (the "Senior Secured Credit Facility Commitment Letter") among the Sponsor,
Credit Suisse First Boston ("CSFB"), NationsBank, N.A. ("NB") and BNP (together
with CSFB and NB, the "Senior Lenders"), the Senior Lenders have agreed to
provide the New Credit Facility to MEDIQ/PRN. The following description is
qualified in its entirety by reference to the Senior Secured Credit Facility
Commitment Letter, which is incorporated herein by reference.
 
    The New 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
(the "Revolving Credit Facility"). Loans made under the Tranche A Term Loan
Facility ("Tranche A Term Loans") and loans made under the Tranche B Term Loan
Facility ("Tranche B Term Loans") constitute "Term Loans." Advances under the
Revolving Credit Facility are referred to as "Revolving Loans."
 
    Term Loans in the aggregate principal amount of $175.0 million will be drawn
on the closing date of the New Credit Facility. Subject to compliance with
customary conditions precedent, loans under the Revolving Credit Facility 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 be available 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 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.
 
                                       53
<PAGE>
    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
Tranche A Term Loans and the Revolving Loans, a margin equal to 1.0%, and in the
case of the Tranche B Term Loans, a margin equal to 1.50%, or (ii) the London
Interbank Offered Rate ("LIBOR"), plus, in the case of the Tranche A Term Loans
and the Revolving Loans, a margin equal to 2.25%, and in the case of the Tranche
B Term Loans, a margin equal to 2.75%. 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 Revolving Credit Facility will be due and payable in full at maturity.
The Term Loans will be subject to mandatory prepayments and reductions in the
event of certain extraordinary transactions or issuances of debt and equity by
MEDIQ/PRN. The Term Loans 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 the Company's ratio of total debt to pro forma EBITDA 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 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 Secured Credit Facility Commitment Letter requires the Sponsor to
cause MQ and the Company to become parties to such letter on or prior to the
consummation of the Merger and provides that the Sponsor will be released
automatically from all its rights, duties and obligations thereunder when the
Company becomes a party thereto.
 
    The Senior Lenders' commitment to provide the New 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 pro forma total debt to
pro forma EBITDA 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
any events, changes or effects which individually or in the aggregate 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 (a "Material Adverse Effect"); (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; (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
 
                                       54
<PAGE>
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 will issue senior subordinated notes (the
"Senior Subordinated Notes") in an aggregate principal amount of $200.0 million
pursuant to the Senior Subordinated Note Offering. The Company will issue senior
discount debentures (the "Discount Debentures") for aggregate gross proceeds of
$30.0 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 by each subsidiary of MEDIQ/PRN that guarantees the New Credit Facility.
The Discount Debentures will be senior, secured obligations of the Company,
ranking PARI PASSU in right of payment with all existing and future senior
secured obligations of the Company and will rank senior to all future
subordinated debt of the Company. The Discount Debentures will be secured by the
capital stock of MEDIQ/PRN that is owned by the Company (after giving effect to
the Transactions), but will not be guaranteed.
 
    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.
 
                                       55
<PAGE>
    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 the Sponsor, 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 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.
 
                                       56
<PAGE>
    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.
 
    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 the Sponsor to cause MQ and the
Company to become parties to such letter on or prior to the consummation of the
Merger and provides that the Sponsor will be
 
                                       57
<PAGE>
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 the
Sponsor, 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 notes
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 the 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 the 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 the Discount Debentures.
 
    If the Initial Purchasers are required to purchase the 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 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 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 the 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 the Sponsor to cause MQ
and the Company to become parties to such letter on or prior to the consummation
of the Merger and provides that the Sponsor 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.

             PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
 
    The following unaudited pro forma condensed consolidated financial
statements (the "Pro Forma Condensed Consolidated Financial Statements") have
been based on the historical consolidated financial statements of the Company as
of and for the year ended September 30, 1997 and the historical income statement
of SpectraCair for the eleven months ended August 31, 1997. The Company acquired
the remaining fifty percent interest in its SpectraCair joint venture on
September 1, 1997, and, accordingly, the Company's historical balance sheet at
September 30, 1997 includes the assets and liabilities of SpectraCair and the
Company's historical consolidated statement of operations include the results of
operations of SpectraCair for the one month ended September 30, 1997.
 
    As a result of the acquisition of SpectraCair 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 Condensed Consolidated Financial Statements do not reflect
the elimination of the above noted items.
 
    The pro forma condensed consolidated balance sheet gives effect to the
Transactions as if they were consummated on September 30, 1997. The pro forma
condensed consolidated statement of operations gives effect to the acquisition
of SpectraCair and the Transactions 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 historical consolidated financial statements and notes
thereto and other information contained in the documents incorporated by
reference herein.
 
    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.

(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 "THE MERGER--Interests of Certain Persons in the Merger."
 
(D) Reflects the increased interest cost related to the New Credit Facility, the
    Discount Debentures and the Senior Subordinated Notes, as follows:

                                  THE COMPANY
 
    The Company, through its wholly-owned subsidiary, MEDIQ/PRN, operates the
largest movable critical care medical equipment rental business in the United
States, serving more than 5,000 hospitals, alternate care facilities, nursing
homes and other health care providers nationwide. The Company rents over 650
different types of movable 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, oxygen concentrators, therapeutic support systems and specialty
hospital bed mattresses and overlays. The Company also sells a variety of
disposable products, accessories and repair parts used with the equipment it
rents, is the exclusive distributor of accessories and supplies manufactured by
Siemens Medical Systems, Inc. for respiratory care, catherization lab and
monitoring systems, and provides outsourcing services, including management,
consulting and administrative services, to health care providers and diagnostic
imaging centers. In fiscal 1997, rentals of movable medical equipment accounted
for approximately 80% of the Company's revenues, sales of disposable products,
equipment, accessories and repair parts used with equipment it rents accounted
for approximately 13% of the Company's revenues and the provision of outsourcing
services accounted for approximately 7% of the Company's revenues.
 
    The Company believes that rentals of medical equipment 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 care. As a result of these competing pressures, hospitals
often elect to rent or lease medical equipment rather than incur the substantial
capital costs required for equipment purchases. Additionally, as health care
costs have steadily increased, hospitals have sought to improve operating
performance by shifting the management of non-core activities such as asset
management and repair and maintenance to third parties. Hospitals and other
health care providers benefit from these programs by reducing operating costs,
increasing efficiency and/or minimizing technical obsolescence of equipment. As
a result, the Company believes that demand for medical equipment rentals and
outsourcing services is growing.
 
    In its critical care medical equipment rental business, the Company rents
its 140,000 unit movable medical equipment inventory to customers through 84
office locations in major metropolitan areas nationwide, 73 of which are
operated by the Company and the remainder of which are operated by independent
distributors. 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 support services, including equipment delivery, inspection, maintenance,
repair and documentation. The Company also rents therapeutic support surfaces
through SpectraCair, the remaining fifty percent (50%) interest of which the
Company did not already own having been acquired in September, 1997. In addition
to these standard rentals, the Company has entered into several revenue-share
arrangements with original equipment manufacturers ("OEM") pursuant to which the
Company rents moveable medical equipment and sells disposable products produced
by the OEM to the Company's customers. Under such arrangements, because the OEM
owns the equipment, the Company is able to generate additional revenues without
any additional capital investment in new equipment.
 
    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
outsourcing services. Each of the Company's outsourcing services benefits from
the Company's extensive distribution network and broad customer base. These
services include: (i) a comprehensive asset management program
(CAMP-Registered Trademark-) which analyzes the critical care equipment usage 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 service which provides safety inspections, preventive maintenance and
repairs for most critical care equipment through a team of more than 170
trained, experienced biomedical technicians, (iii) a logistics and
 
                                       68
<PAGE>
distribution service to assist equipment manufacturers in reducing their
transportation costs through utilization of the Company's nationwide branch
office network and (iv) a medical gas supply program designed to complement the
Company's respiratory equipment rentals.
 
    The Company believes that it can enhance its leadership position through the
continued implementation of its growth strategy. Key elements of such strategy
include (i) focusing on the development of its outsourcing businesses, including
CAMP-Registered Trademark-, biomedical repairs and logistics, (ii) leveraging
its infrastructure to increase sales in non-capital intensive businesses, such
as revenue sharing rentals, sales of parts, equipment and disposables and
outsourcing businesses and (iii) continuing to evaluate potential acquisitions
of critical care and other medical equipment rental companies and companies in
related industries.
 
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 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.

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

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 (the "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    % of the shares of MEDIQ Preferred Stock can elect all of the directors
(other than Outside Directors).
 
    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

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.

Series A Preferred Stock nor any other class or series 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, for the two (2) 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 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 Company 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 Common Stock, par value $.01 per share (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 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 Company 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 Company, 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 Company.
 
PREFERRED STOCK
 
    Following the Merger, the Company will be authorized by its Certificate of
Incorporation, as amended, to issue an aggregate of 30,000,000 shares of
Preferred Stock, par value $.01 per share (the "Surviving Corporation Preferred
Stock"). The Board of Directors will also be empowered under the Company'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
 
                                       71
<PAGE>
the MEDIQ 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
IV hereto, 8,000,000 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 up to 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.
 
    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 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 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.
 
    RANK.  The Series A Preferred Stock will, with respect to dividend rights
and rights on liquidation, winding up and dissolution of the Company, 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 Company (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
Company 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 Company
 
                                       72
<PAGE>
(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 Company 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 Company (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 Company, it will be junior in right of payment to all existing and future
indebtedness and obligations of the Company. The lending facilities to which the
Company will be a party will restrict payment of cash dividends by the Company.
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 Company 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
Company unless the Company 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 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 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 for all Dividend Periods then elapsed have not been paid or
set aside for payment, the amount of such unpaid dividends will be paid before
any sum will be set aside for or applied by the Company to the purchase,
redemption or other acquisition for value of any shares of Series A Junior
Securities (either pursuant to
 
                                       73
<PAGE>
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 Company from repurchasing shares of Series A Junior Securities from a holder
who is, or was, a director or employee of the Company (or an affiliate of the
Company) and (ii) prohibit the Company 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 Company in connection with the
Merger may have an adverse effect on the Company'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; Stockholders' Deficit;
Liquidity."
 
    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 Company 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
Series A Junior Securities. If upon any voluntary or involuntary liquidation,
dissolution or winding up of the Company, 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 Company 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, disolution or winding up of the affairs of the surviving
corporation with respect to the shares of Series A Preferred Stock.
 
    OPTIONAL REDEMPTION.  The Company 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
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.
 
                                       74
<PAGE>
    In the event of a redemption of only a portion of the then outstanding
shares of Series A Preferred Stock, the Company 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 Company on such record date. If a Redemption
Notice has been properly mailed, unless the Company 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 Company, 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 Company
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 Company, or (b) 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. 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 Company, any sale of all or substantially all of the assets of the Company
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 Company.
 
    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 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.

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

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.

and rights on liquidation, winding up and dissolution of the Company, rank
junior to the Series A Preferred Stock and senior to the Series C Preferred
Stock as to dividend distributions or distributions upon the liquidation,
winding up and dissolution of the Company
 
    Although the Preferred Stock will, with respect to dividend rights and
rights on liquidation, rank senior to Series C Preferred Stock issued by the
Company, it will be junior in right of payment to all existing and future
indebtedness and obligations of the Company. 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 Company.
 
    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

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 A Preferred Stock shall not be entitled to
any further participation in any distribution in the event of liquidation,
disolution or winding up of the affairs of the Surviving Corporation with
respect to the shares of Series A Preferred Stock.

of capital stock of the Company, 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 13.50% Cumulative
Compounding Preferred Stock, par value $.01 per share ("Series C Preferred

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.
 
    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

the Series C 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 C Preferred Stock will, with respect to dividend rights
and rights on liquidation, winding up and dissolution of the Company, 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 Company. The Series C Preferred Stock will also be junior in
right of payment to all existing and future indebtedness and obligations of the
Company. 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
Company.
 
    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

                   CERTAIN PROVISIONS OF THE MERGER AGREEMENT
 
    The following is a brief summary of certain provisions of the Merger

Stock, the Merger Agreement, and 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 IV 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

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

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 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 pursuant to clause (i), all MEDIQ
 
                                       79
<PAGE>
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 (iv) 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) (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 (the "Option Consideration"); provided that, with
respect to any person subject to Section 16 of the Securities 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.
 
                                       80
<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
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
 
                                       81
<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
 
                                       82
<PAGE>
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 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.

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 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 will immediately notify MQ of all relevant terms of
any such inquiries, proposals, indications of interest or offers received by the

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

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, (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
 
                                       84
<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 (i) 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 (i)
by the Company; (b) 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 (y) 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. 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 of the Department of Justice 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 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
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
 
                                       85
<PAGE>
requirements of Section 13 or 15(d) of the Exchange Act, for the two (2) 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 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, a wholly-owned
subsidiary of the Company, on terms and conditions reasonably acceptable to MQ
(the "Reorganization").
 
    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 refinancings contemplated

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 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
 
                                       87
<PAGE>
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 $98,600,000. 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.

        (c) by either MQ or the Company, if the Merger has not been consummated

    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 it on and as of

        (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

    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

    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.

    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 hereto, 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 hereto or their respective successors or assigns. The Merger
Agreement may be 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;
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.

    Proposal with the Company, (B) purchase, lease or otherwise acquire 25% or

    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

                                       93
<PAGE>
        (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 MEDIQ 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 Notice Proposal, (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

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

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 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 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.
 
                                       94
<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 certain provisions of the Stockholder
Agreements, copies of which agreements are attached as Annex VI 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.
 
                                       95
<PAGE>
    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.
 
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 its affiliates to,
directly or indirectly (including through its 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 certain provisions of the Rollover
Agreement, a copy of which is attached as Annex VII 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. Capitalized terms that are used in this section and are not defined
have the respective meanings given to them in the Rollover Agreement.
 
                                       96
<PAGE>
    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 specified in the Rollover Agreement.
 
    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
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 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 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
 
                                       97
<PAGE>
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 elect one director of the Company so long as the Rotko Entities
collectively own 5% of the Surviving Corporation Common Stock.
 
    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 proposes 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.

    also a trustee of two additional trusts established by the late Dr. Rotko

                              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. 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 III 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 on the date on which the Merger became effective. Within 120 days
after the Effective Time, either the Company or any stockholder who has 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
 
                                      102
<PAGE>
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 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).
 
                                      103
<PAGE>
    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 III 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
Preferred Stock, par value $.01 per share with a liquidation preference of
$10.00 per share ("Senior Preferred Shares") having the terms set forth on
Exhibit A hereto, except for Shares owned directly or indirectly by Acquiror or
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

    (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

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

    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 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
 
                                       2
<PAGE>
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 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
 
                                       3
<PAGE>
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 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
 
                                       4
<PAGE>
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.
 
    (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
 
                                       5
<PAGE>
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 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.

<PAGE>
    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.
 
    (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
 
                                       7
<PAGE>
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

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

    SECTION 2.2 CAPITALIZATION.  The authorized capital stock of the Company
consists of 40,000,000 Common Shares, value $1.00 per share, and 20,000,000
shares of preferred stock, par value $.50 per share, all of which have been

Shares were reserved for issuance and are issuable upon or otherwise deliverable
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
otherwise deliverable in connection with the exercise of outstanding non- plan
Options and (e) 699,788 Common Shares and 377,253 Preferred Shares were held in

plan or other arrangement under which it was granted; (ii) the number of and
series of Shares subject thereto; (iii) the exercise price and the name of the
option holder, and (iv) the weighted average exercise price of all outstanding
Options. There are no other shares of capital stock or other equity or voting

Subsidiaries is a party or may be bound requiring the issuance, transfer or sale
of any shares of capital stock or other equity or voting securities of the
Company or any securities or rights convertible into or exchangeable or

contracts, commitments, understandings or arrangements by which the Company 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
Share. All of the outstanding Common Shares and Preferred Shares are, and all
Common Shares and Preferred Shares which may be issued pursuant to the exercise
of outstanding Options or upon conversion of Preferred Shares will be, when
issued in accordance with the respective terms thereof, duly authorized, validly
issued, fully paid and nonassessable, issued in material compliance with all
applicable federal and state securities laws and not issued in violation of any
preemptive or similar rights. There are no bonds, debentures, notes or other
indebtedness having general voting rights (or convertible into securities having
such rights) of the Company issued and outstanding. There are no outstanding
obligations of the Company or any of its Subsidiaries to repurchase, redeem or
otherwise acquire any of the Company's equity or voting securities or to provide
funds to or make any investment (in the form of a loan, capital contribution or
otherwise) in any such subsidiary or any other entity. No entity in which the
Company owns, directly or indirectly, less than a 50% equity interest is,
individually or when taken together with all such other entities, material to
the business of the Company and its Subsidiaries taken as a whole.
 
    As used herein, "Options" shall mean options to acquire Common Shares or
Preferred Shares, as the case may be.

    event which with the notice or lapse of time or both would become a default)
    or result in the loss of a material benefit under, or give rise to any right
    of termination, amendment, acceleration or cancellation of, or result in the

Agreement by the Company and the consummation of the transactions contemplated
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.)
 
    SECTION 2.4 SEC FILINGS.
 
    (a) The Company has timely filed all required forms, reports, statements,
exhibits, schedules and other documents required to be filed with the SEC since

respective dates, the Company Public Reports complied in all material respects
with the requirements of the Securities Act, or the Exchange Act, as the case
may be, and the rules and regulations of the SEC promulgated thereunder
applicable to such Company Public Reports, and none of the Company Public
Reports contains any untrue statement of a material fact or omits to state a
material fact required to be stated therein or necessary in order to make the
statements therein, in the light of the circumstances under which they were
made, not misleading except, in each case, to the extent that a Public Company
Report has been amended, revised or superseded by a subsequent filing with the

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

during the periods involved (except as may be indicated in the notes thereto or
required by changes in generally accepted accounting principles) and (iv) fairly
present in all material respects the consolidated financial position of the
Company and its Subsidiaries as of the dates thereof and the consolidated
results of their operations, changes in stockholders equity and cash flows for
the periods then ended (subject, in the case of unaudited quarterly statements,
to normal, recurring, year-end audit adjustments), except that any pro forma
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

losses, occurrences and developments, has had or would reasonably be expected to
have a Material Adverse Effect on the Company. Except as set forth in Schedule
2.5, since September 30, 1997 the Company has conducted its business in the

    SECTION 2.6 LEGAL PROCEEDINGS.  Except as specifically described in the most
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
the Company or any Subsidiary, or for which the Company or any Subsidiary has

that is pending or threatened, or which would reasonably be expected to be

Company after January 1, 1992, which, if adversely determined would reasonably
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

Effect on the Company). The information contained in such Tax Returns is true

reasonably be expected to have a Material Adverse Effect on the Company. Except
as disclosed on Schedule 2.9, neither the Company nor any Subsidiary is
delinquent in the payment of any tax, assessment or governmental charge, except

the Form S-4 (as defined in Section 4.4(g)) will, at the time the Form S-4
becomes effective under the Securities Act of 1933, as amended (the "Securities
Act") contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein in order to make the statements
therein, in light of the circumstances under which they are made, not
misleading, or (ii) the Proxy Statement (as defined in Section 4.4(g)), will, at
the time the Proxy Statement is first mailed to the Company's stockholders or at
the time of the Special Meeting, contain any untrue statement of a material fact
or omit to state any material fact required to be stated therein in order to
make the statements therein, in light of the circumstances under which they are

    SECTION 2.17 PROPERTIES; CONDITION OF ASSETS.
 
    (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
 
                                       18
<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
contained in this Agreement are true and correct in all material respects, and
such representations and warranties do not omit any material fact necessary to
make the statements contained therein, in light of the circumstances under which
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

securities of the Company, and neither the Company nor any of its Subsidiaries
has any rights plan, preferred stock or similar arrangement which has any of the
aforementioned consequences.

Merger, this Agreement and the transactions contemplated hereby are (i) the
affirmative vote of the holders of a majority of the Preferred Shares, and (ii)
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

memorandum prepared by the Company) to any such group or person (or any of their
respective affiliates or associates) or their representatives in connection with

trademarks and copyrights and applications therefor owned by the Company and
each Subsidiary, that are used in the conduct of the business of the Company and

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,
infringing or otherwise adversely affecting the rights of any person with regard
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
 
                                       23
<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;

    health benefit or other fringe benefit of any director, officer or employee

    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
 
                                       27
<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

such information and are directed by such party to treat such information
confidentially. A party hereto shall take, at its sole expense, all commercially
reasonable actions to cause its Representatives to comply with this Section
4.4(a). Each party hereto shall be deemed to have breached this Section 4.4(a)

and shall use all commercially reasonable efforts to cause its Representatives
to, destroy or deliver to the other party, upon request, all Confidential
Information and Evaluation Material, and all copies thereof and upon request, a
party shall certify in writing to the party making such request that all such
Confidential Information and Evaluation Material has been so delivered or
destroyed.
 
    (b) Subject to Section 4.4(a), the Company shall (and shall cause its
Representatives to) afford to the Acquiror (or its Representatives, including
without limitation directors, officers and employees of the Acquiror and its
affiliates and counsel, accountants and other professionals retained by
Acquiror) such access throughout the period prior to the earlier of the
termination of both this Agreement and the Option Agreement (without exercise of
the option thereunder) or the Effective Time to such books, records (including

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
expenses (including attorney's fees) reasonably incurred by the Company in
connection with matters referred to in the immediately preceding sentence. The
Company shall make, subject to the condition that the transactions contemplated

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

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.

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

National Association of Securities Dealers, Inc. if it has used all commercially
reasonable efforts to consult with the other party.

    fees required to be paid, and all printing, mailing and other costs of

    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.

    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

    considering and taking action upon this Agreement. The Proxy Statement shall

    contemplated hereby. The Company will cause its transfer agent to make stock
    transfer records relating to the Company available to the Acquiror.

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

"Confidentiality Agreement")), including the exhibits, schedules, and other
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
One MEDIQ Plaza
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
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

words and also membership or membership interest of a member of a nonstock
corporation; and the words "depository receipt" mean a receipt or other
instrument issued by a depository representing an interest in one or more
shares, or fractions thereof, solely of stock of a corporation, which stock is

series of stock of a constituent corporation in a merger or consolidation to be

        (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
    depository receipts in respect thereof, at the record date fixed to
    determine the stockholders entitled to receive notice of and to vote at the
    meeting of stockholders to act upon the agreement of merger or
    consolidation, were either (i) listed on a national securities exchange or
    designated as a national market system security on an interdealer quotation
    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
    corporation surviving a merger if the merger did not require for its
    approval the vote of the holders of the surviving corporation as provided in
    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
    anything except:
 
           a.  Shares of stock of the corporation surviving or resulting from
       such merger or consolidation, or depository receipts in respect thereof;
 
           b.  Shares of stock of any other corporation, or depository receipts
       in respect thereof, which shares of stock or depository receipts at the
       effective date of the merger or consolidation will be either listed on a
       national securities exchange or designated as a national market system
       security on an interdealer quotation system by the National Association
       of Securities Dealers, Inc. or held of record by more than 2,000 holders;
 
           c.  Cash in lieu of fractional shares or fractional depository
       receipts described in the foregoing subparagraphs a. and b. of this
       paragraph; or
 
           d.  Any combination of the shares of stock, depository receipts and
       cash in lieu of fractional shares or fractional depository receipts
       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.
<PAGE>
    (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
    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
 
                                       2
<PAGE>
    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, 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
 
                                       3
<PAGE>
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.

                     RESTATED CERTIFICATE OF INCORPORATION
                                       OF

Corporation shall have authority to issue is 60,000,000 shares, divided into two

granted to or imposed upon the shares of each such class and upon the shares of
the first series of Preferred Stock:
 
     a. ISSUE IN SERIES. Preferred Stock may be issued from time to time in one
        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;
 
        (vi) The rights of the shares of the series in the event of voluntary or
             involuntary liquidation, dissolution or winding up of the
             Corporation;
<PAGE>
       (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.
 
    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
 
                                       2
<PAGE>
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
    8,000,000 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 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
<PAGE>
       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
       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.
 
           (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 Series A
       Junior Securities and cash in lieu of fractional shares of such Series A
       Junior Securities in connection therewith.
 
                                       2
<PAGE>
           (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
       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 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
       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.
 
           (a) OPTIONAL REDEMPTION.

               the place or places where certificates for shares of Series A
               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 A Preferred

           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 price, then, notwithstanding that
           the certificates evidencing any shares of Series A Preferred Stock so
           called for redemption shall not have been surrendered, (x) on the
           Redemption Date, the shares represented thereby so called for
           redemption shall be deemed no longer outstanding and shall have the

           (d) DEPOSIT OF FUNDS. The Corporation's obligation to deliver funds
       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 A 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
       paragraph 5 following such surrender and following the date of such

        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 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
<PAGE>
       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 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
 
                                       2
<PAGE>
       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.
 
           (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.
 
                                       3
<PAGE>
           (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

    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
    INDEBTEDNESS. To the extent that any action required to be taken by the

       Liquidation Preference (as provided in paragraph A4(a) below) at the time
       of repurchase as provided herein if not earlier declared and paid.

       respect thereof, compounded annually, at the rate of 13.5% per annum.
 
           (b) All dividends paid with respect to shares of Series C Preferred

       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.

       set apart for the payment of dividends or other distributions on any
       Series C Parity Securities for any period, and no Series C Parity

       distributions, redemptions, repurchases or acquisitions payable in Series
       C Junior Securities and cash in lieu of fractional shares of such Series
       C Junior Securities in connection therewith), unless (i) full Accumulated

       Preferred Stock and Series C 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 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.
 
           (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 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
       (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 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 (i) prohibit the
       Corporation from repurchasing shares of Series C 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,
 
                                       2

       redemptions, 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.
 
           (f) Dividends payable on Series C 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.

       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.

           been a sum set apart sufficient for such cash payment on the
           Redemption Date.
 
               (iii) In the event of a redemption pursuant to paragraph A(5)(a)
           hereof of only a portion of the then outstanding shares of Series C

           Stock to be redeemed except as to the Holder or Holders to whom the
           Corporation has failed to give said notice or except as to the Holder

                   (E) that the Holder is to surrender to the Corporation, at
               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
               Stock to be redeemed; and
 
                   (F) that dividends on the shares of Series C Preferred Stock
               to be redeemed shall cease to accumulate on such Redemption Date
               unless the Corporation defaults in the payment of the redemption

           the full redemption price for such shares shall be payable in cash to
           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 price, then, notwithstanding that
           the certificates evidencing any shares of Series C Preferred Stock so
           called for redemption shall not have been surrendered, (x) on the

           (d) DEPOSIT OF FUNDS. The Corporation's obligation to deliver funds
       in accordance with this paragraph (5) shall be deemed fulfilled if, on or
       before a Redemption Date, the Corporation shall deposit, with a bank 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
       paragraph 5 following such surrender and following the date of such

date of which being herein referred to as the "Notice 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
 
                                       2
<PAGE>
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;
 
                                       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.
 
                                       4

under Section 3, prior notification to or approval of any Governmental Entity is

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 facilitate, or furnish or disclose non-public information in
    furtherance of, any inquiries or the making
<PAGE>
    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 instruments as may be necessary to effectuate the intent
    of this proxy and hereby revokes any proxy
 
                                       2
<PAGE>
    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.

    supplemented, except upon the execution and delivery of a written agreement
    executed by the parties hereto.

<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

    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

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 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
<PAGE>
    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 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
 
                                       2
<PAGE>
    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,

    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.

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 facilitate, or furnish or disclose non-public information in
    furtherance of, any inquiries or the making
<PAGE>
    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 instruments as may be necessary to effectuate the intent
    of this proxy and hereby revokes any proxy
 
                                       2
<PAGE>
    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.
 
                                       3
<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.

    prior written consent. The Stockholder agrees that it shall not convert any

    diminishes the benefits of this Stockholder Agreement to the Acquiror.
 
        3. The Stockholder agrees to, and to cause any company, trust or other

<PAGE>
    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,

    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

    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 instruments as may be necessary to effectuate the intent
    of this proxy and hereby revokes any proxy
 
                                       2
<PAGE>
    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,
    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.
 
           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
<PAGE>
       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.
 
                                       2

     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 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
<PAGE>
        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.

ITEM 20 INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
    As permitted by the Delaware Law, the Company's Certificate of Incorporation
provides that directors of the Company shall not be personally liable to the
Company 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 Company or its stockholders, (ii) for acts of 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, relating
to prohibited dividends or distributions or the repurchase or redemption of
stock, or (iv) for any transaction from which the director derives an improper
personal benefit. In addition, the Company's By-laws provide for indemnification
of the Company's officers and directors to the fullest extent permitted under
Delaware law. Section 145 of the Delaware Law provides that a corporation may
indemnify any persons, including officers and directors, who were or are, or are
threatened to be made, parties to any threatened, pending or completed legal
action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of such corporation), by
reason of the fact that such person was an officer, director, employee or agent
of such corporation or is or was serving at the request of such corporation as
an officer, director, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise. The indemnity may include expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement
actually and reasonably incurred by such person in connection with such action,
suit or proceeding, provided such person acted in good faith and in a manner he
reasonably believed to be in or not opposed to the corporation's best interests
and, for criminal proceedings, had no reasonable cause to believe that his
conduct was unlawful. A Delaware corporation may indemnify officers and
directors in an action by or in the right of the corporation under the same
conditions, except that no indemnification is permitted without judicial
approval if the officer or director is adjudged to be liable to the corporation.
Where an officer or director is successful on the merits or otherwise in the
defense of any action referred to above, the corporation must indemnify him
against the expenses that such officer or director actually and reasonably
incurred. Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers or persons controlling
the Company pursuant to the foregoing provisions, the Company has been informed
that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act and
is therefore unenforceable.
 
    The directors and officers of the registrant are insured against certain
liabilities under the registrant's directors' and officers' liability insurance.

ITEM 22 UNDERTAKINGS
 
    The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 that is incorporated by reference in this
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
 
    The undersigned Registrant hereby undertakes as follows: that prior to any
public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed to be underwriters, in addition to the information
called for by the other Items of the applicable form.
 
    The Registrant undertakes that every prospectus (i) that is filed pursuant
to the immediately preceding undertaking or (ii) that purports to meet the
requirements of section 10(a)(3) of the Act and is used in connection with an
offering of securities subject to Rule 415, will be filed as a part of an
amendment to the registration statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933, each such post-effective amendment shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.
 
    Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Registrant of expenses incurred
or paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.
 
                                      II-4

    The undersigned Registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Items 4, 10(b), 11, or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.
 
    The undersigned Registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

undersigned, thereunto duly authorized in the City of Pennsauken, State of New
