     other agreement, or subject to any judgment, decree or order of any court
     or administrative agency, that would interfere with their use of the
     Intellectual Property of MEDIQ Sub or that would conflict with MEDIQ Sub's
     business as heretofore conducted.  Schedule 4.10(a) also identifies all
     Intellectual Property (other than Commercial Rights) of MEDIQ Sub that

     (ii).  No invention that is owned by any employee or consultant of MEDIQ

     shall have the meaning set forth under Section 5000(b)(1) of the Code and
     any regulations promulgated thereunder.
 
          (d) No 'employee pension benefit plan' as defined in Section 3(2) of

              REPRESENTATIONS AND WARRANTIES OF MMI AND MMI SUB
 
     As an inducement to MEDIQ and MEDIQ Sub to enter into this Agreement, MMI
and MMI Sub, as the case may be, represent and warrant as follows:
 
     5.1  Organization and Standing.
 
          (a) Each of MMI and MMI Sub is a corporation duly organized, validly
     existing and in good standing under the laws of the state of its
     incorporation, has all requisite corporate power and authority to own, 
     operate and lease its properties and carry on its business as now 
     conducted, and is duly qualified to do business and is in good standing 
     as a foreign corporation in each jurisdiction in which the failure to so 
     qualify would constitute a Material Adverse Effect on either MMI or MMI 
     Sub.
 
          (b) Each of MMI and MMI Sub has delivered or made available to MEDIQ
     complete and accurate copies of its current Articles of Incorporation or
     Certificate of Incorporation, as the case may be, and Bylaws and minutes of
     all of its directors' and stockholders' meetings.
 
     5.2  MMI Shares and the Warrant.
 
          (a) The MMI Shares and the Warrant which are to be transferred to
     MEDIQ by MMI pursuant hereto are free and clear of any and all
     Encumbrances; 

          (b) MMI has the full right, power and authority to issue and
     transfer to MEDIQ at the Closing the MMI Shares and the Warrant;
 
          (c) The MMI Shares and the Warrant to be issued to MEDIQ as
     contemplated hereunder are duly authorized and, when issued and exchanged
     pursuant to the terms of this Agreement, will be duly authorized, validly
     issued, fully paid, non-assessable and not subject to any preemptive or
     similar rights.
 
     5.3  Authority, Approval and Enforceability.
 
          (a) Each of MMI and MMI Sub has full corporate power and authority to
     execute, deliver and, subject to obtaining the required approvals of the
     holders of MMI Common Stock, perform its obligations under this Agreement,

     Agreement has been duly executed and delivered by each of MMI and MMI Sub.
 
          (b) Neither MMI nor MMI Sub is a party to, subject to or bound by any

     any court or other governmental body which would prevent the execution or
     delivery of this Agreement or consummation of the transactions contemplated
     herein by MMI or MMI Sub.  The execution and delivery by each of MMI and
     MMI Sub of this Agreement does not, and the performance and consummation of
     the transactions contemplated by this Agreement will not, result in any
     conflict with, breach or violation of or default, termination or forfeiture
     under (or upon the failure to give notice or the lapse of time, or both,
     result in any conflict with, breach or violation of or default, termination
     or forfeiture under) any terms or provisions of its Articles of
     Incorporation or Certificate of Incorporation, as the case may be, or
     Bylaws, or any statute, rule, regulation, judicial, governmental,
     regulatory or administrative decree, order or judgment, or any agreement,
     lease or other instrument to which either is a party or to which any of
     their respective assets are subject, the breach, violation, default,
     termination or forfeiture of which would constitute a Material Adverse
     Effect on either MMI or MMI Sub.
 
          (c) No consent, approval, authorization, order, registration, 
     qualification or filing of or with any court or any regulatory authority 
     or any other governmental or administrative body is required on its part 
     for the consummation by each of MMI and MMI Sub, as the case may be, of 
     the transactions contemplated by this Agreement, except (i) the filing of 
     the Certificate of Merger and related officers' certificates with the 
     Secretary of State of the State of Delaware; (ii) such consents, 
     approvals, authorizations, orders, registrations, qualifications and
     filings which, if not obtained or made, would not have a Material Adverse 
     Effect on the ability of MMI and MMI Sub to consummate the transactions 
     contemplated hereunder and (iii) registration of the MMI Shares under the 
     1933 Act and applicable state securities laws.

     Sub and, subject to obtaining the required approvals of the holders of MMI
     Common Stock, MMI, enforceable against each in accordance with the terms
     hereof, except as may be limited by applicable bankruptcy, insolvency,
     reorganization, moratorium or similar laws affecting creditors' rights
     generally and subject to general principles of equity and, with respect to
     MMI, subject to MMI obtaining the required approval of the holders of MMI

          (b) As of its filing date, each of the SEC Filings complied in all

     untrue statement of any material fact or omit to state any material fact
     necessary in order to make the statements made therein, in the light of the
     circumstances under which they were made, not misleading except to the
     extent corrected by a subsequently filed SEC Filing filed prior to the date
     hereof.

          (b) there has not been any satisfaction or discharge by MMI of (i) any
     lien, claim, or encumbrance in favor of MMI or (ii) payment of any

     Material Adverse Effect on MMI;

     Each of MMI, MMI Sub, MEDIQ and MEDIQ Sub, as the case may be, agrees and
covenants to the others, except as expressly provided otherwise herein, as

counsel for any Party hereto.
 
     6.2  Publicity.  Each Party agrees that, from the date hereof through the
Closing Date, no public release or announcement concerning the transactions
contemplated hereby shall be issued by any Party without the prior written
consent of each other party (which consent shall not be unreasonably withheld),
except as such release or announcement may be required by law or the rules or
regulations of any United States or foreign securities exchange or the NASDAQ
National Market System, in which case the party required to make the release or
announcement shall allow each other Party reasonable time to comment on such
release or announcement in advance of such issuance.
 
     6.3  Best Efforts.  Each Party will use all reasonable efforts to cause all
conditions to the Closing to be satisfied.

efforts to cause the Merger to qualify as a tax-free reorganization under
Sections 368(a)(1)(A) and 368(a)(2)(E) of the Code and accordingly will not,
either before or after consummation of the Merger, take any action or fail to
take any action that would prevent the Merger from qualifying as a tax-free
reorganization under Section 368(a)(2)(E) of the Code or be inconsistent with
such qualification.
 
     6.7  Employee Matters.
 
          (a) Except as a provided in Section 9.2(d) hereof, the Parties agree
     that each of MMI, MMI Sub and the surviving corporation shall not be
     required pursuant to this Agreement to offer employment or to continue
     employment to persons employed by MEDIQ Sub ('MEDIQ Sub Employees') as of
     the Closing Date.
 
          (b) The Parties agree that each of MMI and MMI Sub shall not be
     required pursuant to this Agreement to maintain after the Closing any
     compensation and employee benefit plans, arrangements and perquisites
     provided by MEDIQ Sub for any MEDIQ Sub Employee retained by MMI, MMI Sub
     or the surviving corporation.
 
          (c) MEDIQ and MEDIQ Sub shall take all action necessary so that MMI
     and the surviving corporation do not incur any liability or continuing
     obligation after the Closing for any Plan, except to the extent such
     liability has been specifically accrued on the MEDIQ Sub Financials,
     including without limitation MEDIQ Sub's participation in MEDIQ's fully
     funded employee benefits plan(s) and its 401(k) plan and the distribution
     of any benefits thereunder to the respective participants.  MMI shall
     provide to all employees of the surviving corporation, or cause to be
     provided, as of the Effective Time, medical, dental, disability, workers
     compensation, life insurance and other fringe benefits commensurate with
     those benefits that are offered to other employees of R Squared Scan
     Systems, Inc.
 
     6.8  Tax Matters.
 
          (a) MEDIQ will be responsible for and will cause to be prepared and
     duly filed all Returns (as defined in Section 6.8(h)) in which MEDIQ Sub is
     includible for all taxable years ending on or before the Effective Time,
     and all consolidated, combined or similar Returns for periods beginning
     September 30, 1993 and ending at the Effective Time with respect to which
     MEDIQ Sub is includible for such period.  MEDIQ shall prepare that portion
     of any such Returns related to MEDIQ Sub in accordance with the methodology
     used in prior years.  MEDIQ will not amend that portion of any Return
     related to MEDIQ Sub without the written approval of MMI, which approval
     will not be unreasonably withheld.  MEDIQ will pay or cause to be paid, and
     shall indemnify and hold MEDIQ Sub and MMI harmless against, all Taxes (as
     defined in Section 6.8(h)) to which such Returns relate, but only to the
     extent such Taxes have not been specifically accrued on the Closing Balance
     Sheet.

          (b) Other than Returns to be prepared by MEDIQ pursuant to paragraph
     (a), MMI will be responsible for and will cause to be prepared and duly
     filed any and all Returns of MEDIQ Sub for any and all taxable periods
     which include and end after the Effective Time (the 'Overlap Period'), and
     any taxable period beginning after the Effective Time.  MEDIQ will be
     responsible for and will indemnify and hold harmless MEDIQ Sub and MMI with
     respect to all Taxes for the Overlap Period in an amount equal to the
     liability for Taxes that would have resulted had the Overlap Period ended
     at the Effective Time (utilizing, if applicable, the actual tax rate
     imposed on a particular category of income by the applicable taxing
     jurisdiction) and which Taxes have not been accrued on the Closing Balance
     Sheet.  Any amount so payable by MEDIQ will be remitted to MEDIQ Sub at
     least ten business days prior to the due date of the respective returns
     pursuant to written notice by MMI of such due date; provided that MEDIQ
     approves of the amount (such approval not to be unreasonably
     withheld).  MEDIQ Sub shall remit the full amount received from MEDIQ
     pursuant to this Section 6.8(b) to the appropriate Tax authority within the
     time period required by law.
 
          (c) MMI will pay or cause to be paid and shall indemnify and hold
     MEDIQ harmless from and against the following Taxes with respect to taxable
     items of MEDIQ Sub:  (i) any and all Taxes arising in or attributable to
     any taxable period (or that portion of any taxable period) beginning after
     the Closing Date, due or payable by MEDIQ Sub or MEDIQ (computed in a
     manner consistent with the allocation of Taxes for the Overlap Period);
     (ii) any and all Taxes not incurred in the ordinary course of business
     attributable to acts or omissions of MMI or MEDIQ Sub occurring after the
     Closing but on the Closing Date; (iii) any and all Taxes attributable to an
     Overlap Period other than that portion of such Taxes for which MEDIQ is
     responsible pursuant to Section 6.8(b) above; and (iv) any and all Taxes
     arising in or attributable to any taxable period (or that portion of any
     taxable period) ending on or before the Closing Date to the extent provided
     for in the Closing Balance Sheet.
 
          (d) MMI and MEDIQ Sub agree that, with respect to any Tax, MEDIQ Sub
     shall not carry back a net operating loss which arises in any taxable
     period ending after the Closing Date ('Subsequent Loss') to any taxable
     period of MEDIQ ending on or before the Closing Date.  If a Subsequent Loss
     with respect to any Tax is carried back into any taxable period of MEDIQ
     ending on or before the Closing Date, MEDIQ shall be entitled to any refund
     or credit of Taxes realized as a result thereof. This paragraph (d) shall
     not apply to any adjustment to which paragraph (e) applies.
 
          (e) (i) If any adjustment is made to any Tax Return relating to MEDIQ
     or any of its Affiliates (including MEDIQ Sub) for any taxable period (or
     portion thereof) ending on or prior to the Closing Date (whether such
     adjustment is a result of or in settlement of any audit, other
     administrative proceeding or the filing of an amended return to reflect the
     consequences of any determination made in connection with any such audit or
     proceeding or otherwise) and there is a correlative offsetting adjustment
     applicable to MMI or any of its Affiliates (including MEDIQ Sub) for any
     taxable period (or portion thereof) ending after the Closing Date, the
     party whose adjustment is favorable (i.e., the party to which there inures,
     directly or indirectly, a net Tax benefit as the result of any adjustment
     (MMI or MEDIQ, as the case may be)) shall pay to the other party the amount
     of such net Tax benefit at such time or times as and to the
     extent that such benefit is realized through a refund of Tax or actual
     reduction in the amount of Taxes which would otherwise be paid if such
     adjustment had not been made; provided, however, that the party whose 
     adjustment is favorable shall not be required to make a payment to the 
     other party in excess of the amount (if any) of the net Tax detriment to 
     such other party correlative to such net Tax benefit; provided, further, 
     that if the party whose adjustment is favorable realizes a net Tax 
     benefit prior to the time the other party realizes a net Tax detriment, 
     the party whose adjustment is favorable shall not be required to make any
     payment to the other party until such time or times as the net Tax 
     detriment is actually realized by such other party.
 
             (ii) If any adjustment is made to any Tax Return relating to MMI or
        any of its Affiliates (including MEDIQ Sub) for any taxable period (or
        portion thereof) ending after the Closing Date (whether as a result of
        or in settlement of any audit, other administrative proceeding or
        judicial proceeding or the filing of an amended Return to reflect the
        consequences of any determination made in connection with
        any such audit or proceeding or otherwise) and there is a correlative
        offsetting adjustment applicable to MEDIQ or any of its Affiliates
        (including MEDIQ Sub) for any taxable period (or portion thereof) ending
        on or prior to the Closing Date, the party whose adjustment is favorable
        (i.e., the party to which there inures, directly or indirectly, a net
        Tax benefit as the result of any adjustment (MMI or MEDIQ, as the case
        may be)) shall pay to the other party the amount of such net Tax benefit
        at such time or times as and to the extent that such benefit is realized
        through a refund of Tax or actual reduction in the amount of Taxes which
        would otherwise be paid if such adjustment had not been made; provided,
        however, that the party whose adjustment is favorable shall not be
        required to make a payment to the other party in excess of the amount
        (if any) of the net Tax detriment to such other party correlative to
        such net Tax benefit; provided, further, that if the party whose
        adjustment is favorable realizes a net Tax benefit prior to the time the
        other party realizes a net Tax detriment, the party whose adjustment is
        favorable shall not be required to make any payment to the other party
        until such time or times as the net Tax detriment is actually realized
        by such other party.
 
             (iii) If either MMI or MEDIQ makes a payment to the other party
        pursuant to subparagraphs (i) or (ii) above and (a) it is later
        determined by the applicable taxing authority that the party who made
        such payment is not entitled to the net Tax benefit which gave rise to
        such payment, then the party who received such payment shall promptly
        remit to the party who made such payment the amount of such payment that
        is attributable to the disallowed Tax benefit or (b) if, as a result of
        a correlative adjustment, an attribute arising in a later period which
        would otherwise be able to be carried back to the taxable year or years
        in which the party making the payment thereunder realized a net Tax
        benefit (a 'Displaced Carryback') cannot be utilized, the party
        receiving a payment pursuant to this subsection (e) will repay to the
        payer an amount sufficient to place the payer in the same position
        (ignoring for the purpose any potential carryforward of the Displaced
        Carryback) as it would have been if the correlative adjustment had not
        occurred, except that the payer shall subsequently return an amount up
        to such repayment when, as and to the extent the payer actually receives
        a net Tax benefit from the Displaced Carryback.
 
             (iv) For purposes of determining whether a correlative adjustment
        described in this paragraph (e) has a net Tax benefit or detriment to 
        the party affected, (a) all effects of such adjustment, including, 
        without limitation, interest, penalties and additions to Tax required 
        to be paid or received, any Tax imposed upon a refund or reduction in 
        Tax and any Tax consequences occasioned by any payment made or to be 
        made by one party to the other shall be taken into account, and (b) 
        whether a party suffers a Tax detriment or receives a Tax benefit will 
        be determined as if such party filed a separate Return for all periods.
 
          (f) After the Effective Time, MMI and MEDIQ Sub, on the one hand, and
     MEDIQ, on the other hand, will make available to the other, as reasonably
     requested, all information, records or documents relating to the liability
     for Taxes for all periods prior to or including the Effective Time and will
     preserve such information, records or documents until the expiration of any
     applicable statute of limitations or extensions thereof.
 
          (g) Any and all tax sharing, tax indemnity, or tax allocation
     agreements with respect to which MEDIQ Sub was a party at any time prior to
     the Effective Time shall terminate upon the Effective Time.  No further
     amounts shall be payable under such agreements following the Effective
     Time, other than amounts due MEDIQ Sub with respect to all periods through
     and including the Effective Time.
 
          (h) For purposes of this Agreement:  (i) the term 'Taxes' means (A)
     all federal, state, local, foreign and other net income, gross income,
     gross receipts, sales, use, ad valorem, value added, intangible, unitary,
     capital gain, transfer, franchise, profits, license, lease, service,
     service use, withholding, backup withholding, payroll, employment,
     estimated, excise, severance, stamp, occupation, premium, property,
     prohibited transactions, windfall or excess profits, customs, duties or
     other taxes, fees, assessments or charges of any kind whatsoever, together
     with any interest and any penalties, additions to tax or additional amounts
     with respect thereto, (B) any liability for payment of amounts described in
     clause (A) whether as a result of transferee liability, of being a member
     of an affiliated, consolidated, combined or unitary group for any period,
     or otherwise through operation of law and (C) any liability for the payment
     of amounts described in clauses (A) or (B) as a result of any tax sharing,
     tax indemnity or tax allocation agreement or any other express or implied
     agreement to indemnify any other person; and the term 'Tax' means any one
     of the foregoing Taxes; and (ii) the term 'Returns' means all returns,
     declarations, reports, statements and other documents required to be filed
     in respect of Taxes; and the term 'Return' means any one of the foregoing
     Returns.
 
          (i) MEDIQ represents and warrants to MMI  and MMI Sub as follows:
 
             (i) To the extent a failure to do so would constitute a Material
        Adverse Effect on MMI or MEDIQ Sub, MEDIQ Sub, and every member of a
        consolidated, combined, unitary, or other similar group for federal,
        state or local income tax purposes (for the period during which MEDIQ
        Sub was included in that group) all such other entities collectively
        referred to herein as 'Tax Affiliates'), has filed on a timely basis all
        Returns required to have been filed by it and has paid on a timely basis
        all Taxes shown thereon to be due.  All such Returns were true, complete
        and correct as of the date on which they were filed.  The provisions for
        taxes in the Financial Statements set forth the maximum liability of
        MEDIQ Sub for Taxes relating to periods covered thereby.  No liability
        for Taxes has been incurred by MEDIQ Sub since the dates of the 
        Financial Statements other than in the ordinary course of MEDIQ Sub' 
        business.  MEDIQ Sub is not aware of any reasonably possible state of 
        facts, other than the results from its normal business operations, 
        which could result in a liability for Taxes in excess of those shown 
        on the Financial Statements.
 
             (ii) With respect to all amounts in respect of Taxes imposed upon
        MEDIQ Sub or Tax Affiliates, or for which MEDIQ Sub or Tax Affiliates is
        or could be liable, and with respect to all taxable periods or portions
        of periods ending on or before the Effective Time, all applicable Tax
        laws and agreements have been fully complied with, and all such amounts
        required to be paid by MEDIQ Sub or Tax Affiliates to taxing authorities
        or others have been paid.
 
             (iii) Except as otherwise set forth on Schedule 6.8:
 
                (1) None of the Returns required to be filed by  MEDIQ Sub and
           Tax Affiliates contains, or will contain, a disclosure statement
           under Section 6662 (or any predecessor provision) of the Code, or any
           similar provision of state, local or foreign law;
 
                (2) MEDIQ Sub or Tax Affiliates have not received notice that
           the Internal Revenue Service ('IRS') or any other taxing authority
           has asserted against MEDIQ Sub or Tax Affiliates any deficiency or
           claim for additional Taxes in connection with any Return, and no
           issues have been raised (and are currently pending) by any taxing
           authority in connection with any Return;
 
                (3) All Tax deficiencies asserted or assessed against MEDIQ Sub
           and Tax Affiliates have been paid or finally settled;
 
                (4) There is no pending or threatened action, audit, proceeding,
           or investigation with respect to (i) the assessment or collection of
           Taxes or (ii) a claim for refund made by MEDIQ Sub and Tax Affiliates
           with respect to Taxes previously paid;
 
                (5) All amounts that were required to be collected or withheld
           by MEDIQ Sub, or with respect to Taxes of MEDIQ Sub, have been duly
           collected or withheld, and all such amounts that were required to be
           remitted to any taxing authority have been duly remitted;
 
                (6) All Returns have been audited by the IRS or the relevant
           taxing authority, or the time for assessment of additional Taxes with
           respect thereto has been closed by applicable statutes of limitation,
           and all liabilities for Taxes asserted by the IRS (or any other
           relevant taxing authority) have been satisfied, for all taxable years
           ending on or before September 30, 1989; Returns for taxable years
           beginning subsequent to September 30, 1989 remain subject to
           examination;
 
                (7) MEDIQ Sub and Tax Affiliates have not requested an extension
           of time to file any Return not yet filed, and have not granted any
           waiver of any statute of limitations with respect to, or any
           extension of a period for the assessment of, any Tax;
 
                (8) MEDIQ Sub and Tax Affiliates have not taken any action not
           in accordance with past practice that would have the effect of
           deferring any Tax liability of MEDIQ Sub from any taxable period
           ending on or before or including the Effective Time to any subsequent
           taxable period;
 
                (9) None of the income recognized, for federal, state, local or
           foreign income tax purposes, by MEDIQ Sub during the period 
           commencing on October 1, 1993 and ending at the Effective Time will
           be derived other than in the ordinary course of business;
 
                (10) MEDIQ Sub has not filed a consent pursuant to the
           collapsible corporation provisions of Section 341(f) of the Code (or
           any corresponding provision of state, local or foreign income tax
           law) or agreed to have Section 341(f)(2) of the Code (or any
           corresponding provision of state, local or foreign income tax law)
           apply to any disposition of any asset owned by it;

           accounting method or otherwise, nor do MEDIQ Sub or the MEDIQ Sub
           Shareholders have any knowledge that the IRS (or other taxing
           authority) has proposed, or is considering, any such change in
           accounting method or other adjustment;
 
                (14) None of the assets of MEDIQ Sub is property which is
           required to be treated as owned by any other person pursuant to the

     6.8, the representations and warranties in clauses (i), (ii), and
     subclauses 1 through 7, inclusive, 9, 17, 24 and 27 of clause (iii) of

     6.9  Closing Balance Sheet.  Within 90 days after the Closing Date, MEDIQ
will prepare and Deloitte & Touche, the independent certified public accountants
('MEDIQ's Auditors'), will audit and present to MMI and MEDIQ a balance sheet of
MEDIQ Sub as of the Closing Date (the 'Proposed Closing Balance Sheet') together
with their calculation of the Net Tangible Assets of MEDIQ Sub as of the Closing
Date (the 'Closing Calculation').  The Proposed Closing Balance Sheet shall
present fairly the financial position of MEDIQ Sub as of the Closing Date in
accordance with GAAP using practices and procedures consistent with the
preparation of the Audited Financials, except as required by or otherwise in
connection with SFAS 109. MMI and its independent certified public accountants
('MMI's Auditors') shall have the right to review the workpapers of MEDIQ's
Auditors (the 'Workpapers') utilized in preparing the Proposed Closing Balance
Sheet and calculating the Closing Calculation for purposes of verifying the
accuracy and fairness of the Proposed Closing Balance Sheet and the Closing
Calculation.  The Proposed Closing Balance Sheet and the Closing Calculation
shall be binding upon MMI unless MMI gives written notice of disagreement
with any of said values or amounts to MEDIQ within 10 days after its
receipt of the Workpapers, specifying the nature and extent of such
disagreement.  If MMI and MEDIQ mutually agree upon a balance sheet and/or the
Net Tangible Assets of MEDIQ Sub as of the date which is 10 days after MEDIQ's
receipt of such notice from MMI, such agreement shall be binding upon MMI and
MEDIQ.  If MMI and MEDIQ are unable to resolve any such disagreement before such
date, the disagreement shall be referred for final determination to an
independent accounting firm of national reputation mutually acceptable to MMI
and MEDIQ (the 'Selected Firm'), and the resolution of that disagreement and the
calculation of the Net Tangible Assets of MEDIQ Sub resulting therefrom shall be
final and binding upon MMI and MEDIQ for purposes of this Agreement.  The
Proposed Closing Balance Sheet as finally determined is the 'MEDIQ Sub Closing
Balance Sheet.'  The fees and disbursements of MEDIQ's Auditors incurred in the
preparation of the Proposed Closing Balance Sheet submitted to MMI and the audit
thereof shall be paid by MEDIQ Sub.  MMI shall pay the fees and disbursements of
the MMI's Auditors.  The fees and disbursements of the Selected Firm shall be
paid by MMI and MEDIQ as the Selected Firm shall determine based upon its
assessment of the relative merits of the positions taken by each in any
disagreement presented to such firm.
 
     6.10  Preparation of Proxy or Information Statement.  MMI, acting through
its board of directors, shall cause a special meeting (the 'Special Meeting') as
soon as practicable after the date hereof, if determined by MMI, with advise of
its legal counsel, to be necessary or desirable, for the purpose of submitting
this Agreement and all actions contemplated hereby for approval of MMI's
shareholders.  MMI, with the cooperation of MEDIQ, will use all reasonable best
efforts to obtain and furnish the information required to be included by it in a
Proxy Statement or, if MMI, with the advice of legal counsel, reasonably
determines, an Information Statement (i) to file a Proxy Statement or
Information Statement, as the case may be, with the SEC as soon as practicable
after the date hereof, (ii) to respond as soon as possible to any comments of
the SEC relating to the Proxy Statement or Information Statement, as the case 
may be, and any preliminary version thereof and (iii) to cause the definitive 
Proxy Statement or Information Statement, as the case may be, relating to this
Agreement and the transactions contemplated hereby and thereby to be mailed to
its shareholders, as soon as reasonably practicable.  The Proxy Statement or
Information Statement, as the case may be, and all amendments and supplements
thereto, shall comply with applicable law.  Each of MMI and MEDIQ agrees to
provide promptly to the other such information concerning its business and
financial statements and affairs as the other shall reasonably request and as
shall be reasonably required in connection with the action to be taken by MMI to
prepare the Proxy Statement or Information Statement, as the case may be, or any
amendments or supplements thereto, and each of MMI and MEDIQ agrees to cause
their respective counsel and auditors to cooperate with the other's counsel and
auditors in the preparation thereof.  MMI will promptly advise MEDIQ, and MEDIQ
will promptly advise MMI, in writing if at any time prior to the Effective Time
either MMI or MEDIQ shall obtain knowledge of any facts that might make it
necessary or appropriate to amend or supplement the Proxy Statement or
Information Statement, as the case may be, in order to make the statements
contained or incorporated by reference therein not misleading 
or to comply with applicable law.  Anything to the contrary
contained herein notwithstanding, MMI shall not include in the Proxy Statement
or Information Statement, as the case may be, any information with respect to
MEDIQ or its affiliates or associates, the form and content of which information
shall not have been approved by MEDIQ prior to such inclusion, such approval not
to be unreasonably withheld.
 
     6.11  Suppliers and Customers.  (a) At the Closing, MEDIQ Sub shall deliver
Schedule 6.11(a) to MMI setting forth a list (by name, address and person to
contact) of the 20 largest customers of MEDIQ Sub and (b) as soon as practicable
after the date hereof, MEDIQ Sub shall deliver Schedule 6.11(b) to MMI setting
forth a list (by name, address and persons to contact) of the 20 largest
suppliers of MEDIQ Sub, each such schedule for the 12-month period ended
September 30, 1993 together with the approximate dollar amount of purchases and
sales during said period and a summary description of the products purchased or
sold, as applicable; provided, however, that prior to the Closing neither MMI
nor MMI Sub shall contact the suppliers set forth on Schedule 6.11(b) regarding
the accounts described therein without MEDIQ's prior written consent (such
consent not to be unreasonably withheld).  Except as set forth in Schedule
6.11(b), MEDIQ Sub does not have any sole source suppliers (othen than in
situations where alternative sources are readily available).

     business, goodwill and its relationships with customers, suppliers,

     it did prior to the date of this Agreement.  MEDIQ Sub will use all
     reasonable efforts to keep and maintain the existing favorable business
     relationship with each of such customers, suppliers, officers, employees

     material operating decisions (including, without limitation, proposed
     employee hiring, layoff and termination decisions).  Notwithstanding the

to MMI, its accountants, legal counsel and other representatives during such
period all such information concerning MEDIQ Sub's affairs as MMI may reasonably
request but subject to Section 13.10 below (confidentiality and nondisclosure 
agreements); provided, that subject to Section 9.2(b) hereof, any furnishing 
of such information pursuant hereto or any investigation by MMI shall not 
affect MMI's right to rely on the representations, warranties, agreements and 
covenants made by each of MEDIQ and MEDIQ Sub in this Agreement; and, provided,
further, however, that nothing contained herein shall require MEDIQ and MEDIQ 
Sub to furnish any information on a 'by customer' basis, but only on an 
aggregate basis except as specifically provided in Section 6.11 hereof. MEDIQ 
and MEDIQ Sub shall deliver to MMI all written documentation requested by it

distributed to its stockholders free and clear of all Encumbrances as soon as
practicable following the registration of the MMI Shares by MMI pursuant to the
terms and conditions of Article XI hereof, but in no event later than 60 days

                               COVENANTS OF MMI
 
     MMI covenants to MEDIQ and MEDIQ Sub, as the case may be, as follows:
 
     8.1  Nomination of Two Directors to MMI Board.
 
          (a) As of the Closing and thereafter until the distribution by MEDIQ
     of the MMI Shares to its stockholders, MMI shall cause two individuals 
     designated in writing by MEDIQ (collectively, the 'MEDIQ Designees') 
     after the Closing Date and not later than 60 days in advance of the next 
     meeting held for the purpose of electing directors to be nominated for 
     election to the board of directors of MMI; provided, however, that MEDIQ 
     in its written designation of such individuals shall provide MMI with (i)
     such information regarding each designee proposed by MEDIQ as would be 
     required to be included in a proxy statement filed pursuant to the proxy 
     rules of the United States Securities and Exchange Commission had the 
     nominee been nominated, or intended to be nominated, by the Board of 
     Directors of MMI, (ii) the consent of each nominee to serve as a director
     of MMI if so elected and (iii) any other information reasonably requested
     by MMI.
 
          (b) In the event either MEDIQ Designee shall cease to serve as a
     director of MMI prior to distribution of the MMI Shares by MEDIQ to its
     stockholders, MEDIQ shall have the right, (i) unless in breach of its
     obligation to distribute the MMI Shares in accordance with Section 7.12
     hereof or (ii) upon a distribution by MEDIQ of the MMI Shares or the
     Warrant in violation of the 1933 Act or applicable state securities laws,
     to designate another individual, reasonably acceptable to a majority of the
     other members of the board of directors of MMI, to fill the vacancy created
     by such cessation in order to serve as a member of the board of directors
     of MMI; provided, however, that MEDIQ in its written designation of such
     individual shall provide MMI with such information regarding each designee
     proposed by MEDIQ as would be required to be included in a proxy statement
     filed pursuant to the proxy rules of the United States Securities and
     Exchange Commission had the nominee been nominated, or intended to be
     nominated, by the board of directors of MMI, and any other information
     reasonably requested by MMI.  The board of directors of MMI shall review
     such information and determine whether such designee is reasonably
     acceptable to serve as a member of the board of directors of MMI (such
     chosen designee, a 'Successor') as soon as reasonably practicable following
     MEDIQ's designation of such individual.  The process set forth in this
     Section 8.1(b) shall be repeated until such vacancy no longer exists.
 
          (c) MMI hereby covenants and agrees (i) to exercise its reasonable and
     good faith efforts as of the Effective Time and until the MMI Shares are
     distributed by MEDIQ to its stockholders, to cause the MEDIQ Designees and
     any Successor to serve as members of the board of directors of MMI and (ii)
     as of the Closing Date and until such time as the MMI Shares are
     distributed by MEDIQ to its stockholders, to cause the board of directors
     of MMI to consist of no more than seven members.
 
     8.2  Absence of Certain Changes to MMI.  Prior to the Closing, except as
expressly permitted or contemplated hereby, MMI will not, without MEDIQ's prior
written consent (which consent shall not be unreasonably withheld):
 
          (a) set aside or pay any dividend to its shareholders except (i)
     dividends consistent with past practices (but not greater than $0.04 per
     share) and (ii) a special dividend of $0.15 per share (not including
     dividends described in subsection (i) immediately above), or make any 
     distribution of assets to, or repurchase any MMI Common Stock or other 
     securities from its shareholders;
 
          (b) issue or grant any securities or securities convertible into
     capital stock or grant or issue any options, warrants or rights to
     subscribe for capital stock or securities convertible into capital stock;
 
          (c) amend (other than an amendment to increase the compensation
     payable or to become payable thereunder) or terminate the employment
     contract of Mr. Alan D. Margulis as President and Chief Executive Officer;
 
          (d) acquire or dispose of any properties or assets used in MMI's
     business the individual value of which exceeds $50,000 except in the
     ordinary course of business;
 
          (e) amend MMI's Articles of Incorporation or Bylaws; or
 
          (f) engage in any activities or transactions outside the ordinary
     course of MMI's business as currently conducted.
 
     8.3  Material Operating Decisions.  Prior to the Effective Time MMI agrees
to consult with MEDIQ concerning any of its material operating decisions
(including, without limitation, proposed employee hiring, layoff and termination
decisions). Notwithstanding the foregoing MEDIQ expressly acknowledges that MMI
alone shall make such operating decisions and if the Merger does not close,
MEDIQ shall have no liability to MMI in respect to such consultation; and if the
Merger does close, such consultation shall not effect the rights of MEDIQ set
forth in Article X hereof.
 
     8.4  Access to Information.  Each of MMI and MMI Sub will give MEDIQ and
its accountants, legal counsel and other representatives full access, during
normal business hours throughout the period prior to the Closing, to all of the
properties, books, contracts, commitments and records relating to their
respective business, assets and liabilities, and each of MMI and MMI Sub will
furnish to MEDIQ, its accountants, legal counsel and other representatives
during such period all such information concerning their respective affairs as
MEDIQ may reasonably request but subject to Section 13.10 below (confidentiality
and nondisclosure agreements); provided, that, subject to Section 9.3(b) hereof,
any furnishing of such information pursuant hereto or any investigation by MEDIQ
shall not affect MEDIQ's right to rely on the representations, warranties,
agreements and covenants made by each of MMI and MMI Sub in this Agreement.
 
     8.5  Commitment to Favorable Vote.  MMI agrees to vote all shares of MMI
Sub Common Stock held by it in favor of the approval of this Agreement and the
transactions contemplated herein.
 
     8.6  MEDIQ Guarantees.  MMI will use its reasonable efforts to obtain
releases of MEDIQ from its guarantees of indebtedness of MEDIQ Sub.  To the
extent any such release shall not be obtained, MMI shall indemnify MEDIQ and
hold MEDIQ harmless against all liability or obligation arising out of such
guarantees.
 
     8.7  MMI Qualifications.  To the extent that MMI is not qualified to do
business and in good standing in any jurisdiction in which it is required to be
qualified, MMI shall use its reasonable efforts to become so qualified and in
good standing prior to the Effective Time.

the earlier of (i) the distribution of the MMI Shares to the stockholders of
MEDIQ pursuant to a registration statement prepared by MMI in accordance with
Article XI hereof and (ii) April 30, 1995 (the earlier date, the
'Indemnification Cut-off Date'), except with respect to the obligations,
representations and warranties set forth in Section 6.8(i) hereof (tax matters)
which shall terminate sixty days following the expiration of the statute of
limitations applicable to the Tax with respect to which the representation or
warranty applies (the 'Tax Indemnification Cut-off Date'), and, in either case,
except to the extent that a Notice (as defined in Section 10.3 below) has been
delivered to MEDIQ prior to the Indemnification Cut-off Date or the Tax
Indemnification Cut-off Date, as applicable in respect of claims for
indemnification set forth in such Notice.
 
     Except as set forth in the immediately succeeding sentence, MEDIQ shall
have no obligations under this Section 10.1 unless and until the aggregate
amount of liability for Losses to MMI and the surviving corporation exceeds
$300,000, whereupon MEDIQ shall be liable to indemnify for all such amounts over
$300,000 up to a maximum aggregate of Ten Million Dollars ($10,000,000).
 
     In any case in which claims for indemnification have been asserted by MMI
or the surviving corporation and have been set forth in a Notice, all Parties
agree that the indemnity obligations of MEDIQ with respect to such matters shall
continue in full force and effect until such matters have been settled by
agreement of the Parties or by resolution of such matters in accordance with the
terms of this Agreement. Subject to Section 9.2(b) no
disclosure by MEDIQ or MEDIQ Sub other than the disclosure contained in this
Agreement, including the schedules hereto, nor any investigation made by or on
behalf of MMI or MMI Sub with respect to MEDIQ or MEDIQ Sub shall be deemed to
affect MMI's reliance on the representations, warranties, covenants and
agreements made by MEDIQ or MEDIQ Sub contained in this Agreement
and shall not constitute a waiver of MMI's or the surviving corporation's
rights to indemnity as herein provided for the breach or inaccuracy of or
failure to perform or comply with any of MEDIQ's or MEDIQ Sub's representations,
warranties, covenants or agreements under this Agreement.
 
     10.2  Indemnification of MEDIQ.  MMI agrees to indemnify, defend and hold
harmless MEDIQ from and against and shall reimburse MEDIQ against and in respect
of any and all Losses that MEDIQ shall incur or suffer and which arise from or
are attributable to, by reason of or in connection with any breach or inaccuracy
of or any failure to perform or comply with any of MMI's representations,
warranties, agreements or covenants contained in this Agreement, including all
schedules and certificates referred to herein and officers' certificates
required to be delivered hereunder; provided, however, that indemnification for
matters specifically contemplated by Section 11.6 shall be governed by such
section and not this Section 10.2.
 
     The indemnity obligations of MMI pursuant to this Section 10.2 for a breach
or inaccuracy of or a failure to perform or comply with any or all of such
representations, warranties, covenants and agreements shall terminate upon the
Indemnification Cut-off Date, except to the extent a Notice (as defined in
Section 10.3) has been delivered to MMI prior to the Indemnification Cut-off
Date in respect of claims for indemnification set forth in such Notice.
 
     MMI shall have no obligations under this Section 10.2 unless and until the
aggregate amount of liability for Losses to MEDIQ exceeds $300,000, whereupon
MMI shall be liable to indemnify MEDIQ for all such amounts over $300,000 up to
a maximum aggregate of Ten Million Dollars ($10,000,000).
 
     In any case in which claims for indemnification have been asserted by MEDIQ
and have been set forth in a Notice, all Parties agree that the indemnity
obligations of MMI with respect to such matters shall continue in full force and
effect until such matters have been settled by agreement of the Parties or by
resolution of such matters in accordance with the terms of this
Agreement.  Subject to Section 9.3(b), no disclosure by MMI or MMI Sub other
than the disclosure contained in this Agreement, including the schedules hereto,
nor any investigation made by or on behalf of MEDIQ or MEDIQ Sub, with respect
to MMI or MMI Sub shall be deemed to affect MEDIQ's reliance on the
representations, warranties, covenants and agreements made by MMI or MMI Sub
contained in this Agreement and shall not constitute a waiver of MEDIQ's rights
to indemnity as herein provided for the breach or inaccuracy of or failure to
perform or comply with any of MMI's or MMI Sub's representations, warranties,
covenants or agreements under this Agreement.
 
     10.3  Procedure for Indemnification
 
          (a) In the event that a Party shall incur or suffer any Losses in
     respect of which indemnification may be sought by such party pursuant to
     the provisions of this Article X, the party seeking to be indemnified
     hereunder (the 'Indemnitee') shall assert a claim for indemnification by
     written notice (a 'Notice') to the party from whom indemnification is
     sought (the 'Indemnitor') briefly stating the nature and basis of such
     claim.  In the case of Losses arising by reason of any third party claim,
     the Notice shall be given within 25 days of the filing or other written
     assertion of any such claim against the Indemnitee, but the failure of the
     Indemnitee to give the Notice within such time period shall not relieve 
     the Indemnitor of any liability that the Indemnitor may have to the 
     Indemnitee except to the extent that the Indemnitor is actually prejudiced
     thereby; provided, however, that any such notice shall be given no later 
     than the Indemnification Cut-off Date, or the Tax Indemnification Cut-off
     Date, as applicable.
 
          (b) The Indemnitee shall provide to the Indemnitor on request all
     information and documentation reasonably necessary to support and verify
     any Losses which the Indemnitee believes give rise to a claim for
     indemnification hereunder and shall give the Indemnitor reasonable access
     to all books, records and personnel in the possession or under the control
     of the Indemnitee which would have bearing on such claim.
 
          (c) In the case of third party claims for which indemnification is
     sought, the Indemnitor shall have the option (i) to conduct any proceedings
     or negotiations in connection therewith, (ii) to take all other steps to
     settle or defend any such claim (provided that the Indemnitor
     shall not settle any such claim without the
     consent of the Indemnitee, which consent shall not be unreasonably
     withheld) and (iii) to employ counsel to contest any such claim or
     liability in the name of the Indemnitee or otherwise.  In any event, the
     Indemnitee shall be entitled to participate at its own expense with its own
     counsel in any proceedings relating to any third party claim.  The
     Indemnitor shall, within 25 days of receipt of the Notice, notify the
     Indemnitee of its intention to assume the defense of the claim.  Until the
     Indemnitee has received notice of the Indemnitor's election whether to
     defend any claim, the Indemnitee shall take reasonable steps to defend (but
     may not settle) such claim and the reasonable costs and expenses (including
     the reasonable fees and expenses of counsel) in connection therewith shall
     be reimbursed by Indemnitor if and to the extent the claim itself is one
     for which indemnification is owing hereunder.  If the Indemnitor shall
     decline to assume the defense of any such claim, or shall fail to notify
     the Indemnitee within 25 days after receipt of the notice of the
     Indemnitor's election to defend such claim, the Indemnitee may settle such
     claim (provided that any such settlement without the prior written consent
     of the Indemnitor shall not be determinative of the amount of any
     Loss).  If the Indemnitor notifies the Indemnitee that it wishes to accept
     a bona fide written offer from any such claimant or plaintiff (which offer
     includes a release of the Indemnitor from all liability in respect of such
     claim), and the Indemnitee does not consent to such settlement, the
     Indemnitor shall not be liable under this Section 10.3 for the amount by
     which any subsequent settlement or judgment with respect to such claim
     exceeds such bona fide written settlement offer.  The expenses of all
     proceedings, contests or lawsuits in respect of such claims shall be borne
     by the Indemnitor if and to the extent such third party claim itself is one
     for which indemnification is owing hereunder.  Regardless of which Party
     shall assume the defense of the claim, the Parties agree to cooperate fully
     with one another in connection therewith. If and to the extent the
     Indemnitor is responsible pursuant hereto to indemnify the Indemnitee in
     respect of a third party claim then within 10 days after the occurrence of
     a settlement or judgment with respect to such third party claim, the
     Indemnitor shall deliver to the Indemnitee, at the Indemnitor's option
     either: (a) the number of shares (in whole shares) of MMI Common Stock that
     have an aggregate value (valued at $5.25 per share) most nearly equal to 
     the amount of any Losses (or such portion thereof as the
     Indemnitor shall be responsible for pursuant to the provisions hereof), or
     (b) cash equal to the amount of any Losses (or such portion thereof as the
     Indemnitor shall be responsible for pursuant to the provisions hereof).  
     In the event that any Losses incurred by the Indemnitee do not involve 
     payment by the Indemnitee of a third party claim, then, if and to the 
     extent the Indemnitor is responsible pursuant hereto to indemnify the 
     Indemnitee against such Losses, the Indemnitor shall within 10 days after
     agreement on the amount of Losses or the determination of the amount by 
     an arbitrator in accordance with Section 10.4 hereof deliver to the 
     Indemnitee at the Indemnitor's option either:  (a) the number of shares 
     (in whole shares) of MMI Common Stock that have an aggregate value (valued
     at $5.25 per share) most nearly equal to the amount of such Losses
     (or such portion thereof as the Indemnitor shall be responsible for 
     pursuant to the provisions hereof), or (b) cash equal to the amount of 
     such Losses (or the portion thereof as the Indemnitor shall be responsible
     for pursuant to the provisions hereof). Any shares of MMI Common Stock 
     delivered by (i) MEDIQ to MMI to satisfy Losses shall be cancelled and 
     (ii) MMI to MEDIQ to satisfy Losses shall be deemed fully paid and 
     nonassessable.
 
     10.4  Arbitration.  Any controversy involving a claim by an indemnified
party pursuant to this Article X shall be finally settled by arbitration in Los
Angeles, California, in accordance with the then-current Commercial Arbitration
Rules of the American Arbitration Association, and judgment upon the award
rendered by the arbitrator may be entered in any court having jurisdiction
thereof.  Such arbitration shall be conducted by  an arbitrator chosen by mutual
agreement of MMI and MEDIQ.  Failing such agreement, the arbitration shall be
conducted by 3 independent arbitrators, none of whom shall have any competitive
interest with MMI or MEDIQ:  MMI shall choose one such arbitrator, MEDIQ shall
choose one such arbitrator, and such two arbitrators shall mutually select a
third arbitrator.  Any decision of two such arbitrators shall be binding on MMI
and MEDIQ.  There shall be limited discovery prior to the arbitration hearing,
subject to the discretion of the arbitrators, as follows: (a) exchange of
witness lists and copies of documentary evidence and documents related to or
arising out of the issues to be arbitrated, (b) depositions of all party
witnesses, and (c) such other depositions as may be allowed by the arbitrator
upon a showing of good cause.  Depositions shall be conducted in accordance with
the California Code of Civil Procedure.  Each party shall pay its own costs and
expenses (including counsel fees) of any such arbitration except that the
arbitrator can compel one Party to pay all or a portion of the other Party's
costs and expenses.

     10.5  Survivability of Representations, Warranties, Covenants and
Agreements.  Except as expressly set forth herein, each Party's respective
representations, warranties, covenants and agreements contained in this
Agreement and any other document delivered in connection herewith shall
terminate and be of no further force and effect after the date which is the
Indemnification Cut-off Date, except with respect to (i) the representations and
warranties set forth in Section 6.8(i) hereof (tax matters) which shall
terminate and be of no further force and effect after the date which is the Tax
Indemnification Cut-off Date and (ii) the covenants and agreements of either MMI
or MEDIQ set forth herein which by their terms pertain to periods following the
Indemnification Cut-off Date.
 
     10.6  Exclusive Remedy.  Except as set forth herein, the respective
indemnity obligations of MMI and MEDIQ pursuant to this Article X, (together
with all of MMI Parties' and MEDIQ Parties' representations, warranties,
covenants and other agreements) shall survive the Closing and the indemnity
obligations set forth in this Article X, absent fraud, shall be the exclusive
remedy of MMI and MEDIQ, with respect to matters resulting in Losses; provided
that the Parties recognize and agree that in the event of a breach by the MMI
Parties on the one hand or the MEDIQ Parties on the other hand of the covenants
and agreements set forth in Sections 6.5, 7.5, 7.9, 7.11, 7.12, 8.1, 8.5, and
Article 11 that money damages would not be an adequate remedy to either for such
breach and, even if money damages were adequate, it would be impossible to
ascertain or measure with any degree of accuracy the damages sustained by the
respective Parties therefrom and, accordingly, if there should be a breach or
threatened breach of such sections, the Party to be harmed thereby shall be
entitled to an injunction restraining the other or others from any breach
without showing or proving actual damages. Nothing in the preceding sentence
shall limit or otherwise affect any remedies the Parties may otherwise have
against each other under Applicable Law.  Notwithstanding anything to the
contrary contained herein, such covenants and agreements shall survive the
Closing and terminate only upon expiration of the applicable statutes of
limitations.
 
                                  ARTICLE XI
 
                             REGISTRATION RIGHTS
 
     11.1  Definitions.  For purposes of this Article XI:
 
          (a) The terms 'register,' 'registered,' and 'registration' refer to a
     registration effected by preparing and filing a registration statement in
     compliance with the 1933 Act and the declaration or ordering of
     effectiveness of such registration statement; and
 
          (b) The term 'Registrable Securities' refers to the MMI Shares, the
     Noncompetition Shares, the Warrant and Warrant Shares and any MMI Common
     Stock issued as a dividend or other distribution with respect to, or in
     exchange or in replacement thereof except that the MMI Shares, the
     Noncompetition Shares, the Warrant or Warrant Shares (or any particular
     shares thereof) shall cease to be Registrable Securities when and to the
     extent (i) except as otherwise contemplated by Section 11.2(b) hereof, a
     registration statement with respect to the sale of the MMI Shares, the
     Noncompetition Shares, the Warrant or Warrant Shares has become effective
     under the 1933 Act and the MMI Shares, the Noncompetition Shares, the
     Warrant and Warrant Shares have been disposed of in accordance with such
     registration statement; or (ii) the MMI Shares, the Warrant or Warrant
     Shares cease to be outstanding; or (iii) except as otherwise contemplated
     by Section 11.2(b), the MMI Shares shall have been distributed to the
     stockholders of MEDIQ pursuant to the provisions beginning 'provided,
     however' in Section 7.12 hereof.
 
     11.2  Registration.
 
          (a) MMI shall employ its reasonable efforts to cause all Registrable
     Securities to be registered under the 1933 Act as soon as reasonably
     practicable after the filing of its annual report on Form 10-K for the
     fiscal year ending April 28, 1995; provided, however, that if MMI shall
     furnish to MEDIQ a certificate signed by its President stating that, in the
     good faith judgment of the board of directors of MMI, it would be 
     detrimental to MMI or its shareholders for a registration statement to be
     filed in the near future, then MMI shall have the right to defer the 
     filing of a registration statement with respect to such Registrable 
     Securities until such time as the board of directors of MMI deems 
     advisable, but in no event later than November 30, 1995, and thereafter 
     shall employ its reasonable efforts to cause all Registrable Securities 
     to be registered under the 1933 Act as soon as practicable.

     MMI shall be obligated to effect only one registration pursuant to this
Article XI.
 
          (b) The registration referred to in Section 11.2(a) hereof shall cover
     the subsequent sale of Registrable Securities distributed to any MEDIQ
     stockholders who may also then be deemed an 'affiliate' (as defined in the
     1933 Act) of MMI (each such Person, an 'Affiliate Stockholder'), and MMI
     shall cause the registration statement with respect to such Affiliate
     Stockholders' Registrable Securities to remain effective for 180 days after
     first becoming effective; provided, however, that no Affiliate Stockholder
     shall sell an amount of Registrable Securities to any one purchaser
     constituting more than 5% of then outstanding MMI Common Stock pursuant to
     the registration statement.
 
          (c) MMI and MEDIQ shall enter into a 'piggy-back' registration rights
     agreement which shall contain customary terms and conditions,
     including  without limitation (i) the transfer of such rights from MEDIQ to
     Affiliate Stockholders upon distribution pursuant to Section 7.12 hereof,
     (ii) the period such rights shall survive which shall be for a period of
     two years following the expiration of the 180-day period referred to in
     Section 11.2(b) above and (iii) indemnification provisions substantially
     similar to those provided for in Section 11.6 hereof.
 
          (d) Nothwithstanding anything to the contrary in Section 13.13 hereof,
     it is expressly agreed that the Affiliate Stockholders at the time of the
     distribution pursuant to Section 7.12 are intended thrid party
     beneficiaries of Article XI as applicable to such Affiliate Stockholders.
 
     11.3  Obligations of MMI.  Whenever required under paragraph 11.2 to use
its reasonable efforts to effect the registration of any Registrable Securities,
MMI shall, as expeditiously as reasonably possible:
 
          (a) Prepare and file with the SEC a registration statement with
     respect to such Registrable Securities and use its best efforts to cause
     such registration statement to become effective.
 
          (b) Prepare and file with the SEC such amendments and supplements to
     such registration statement and the prospectus used in connection with such
     registration statement as may be necessary to comply with the provisions of
     the 1933 Act with respect to the disposition of all securities covered by
     such registration statement.
 
          (c) Furnish to MEDIQ such numbers of copies of a prospectus, and such
     other documents as it may reasonably request in order to facilitate the
     disposition of Registrable Securities owned by it.
 
          (d) Use its reasonable efforts to register and qualify the securities
     covered by such registration statement under such other securities or Blue
     Sky laws of such jurisdictions as shall be reasonably appropriate for the
     distribution of the securities covered by the registration statement,
     provided that MMI shall not be required in connection therewith or as a
     condition thereto to qualify to do business or to file a general consent to
     service of process in any such states or jurisdictions.
 
     11.4  Condition Precedent.  It shall be a condition precedent to the
obligations of MMI to take any action pursuant to this Article XI that MEDIQ
shall furnish to MMI information regarding MEDIQ, the Registrable Securities
held by MEDIQ and other such information as MMI shall reasonably request and as
shall be required in connection with the action to be taken by MMI.
 
     11.5  Expenses of Registration.  All expenses incurred by MMI in connection
with preparation of a registration statement, I including without limitation all
registration and qualification fees, printers' and accounting fees, fees and
disbursements of counsel for MMI shall be borne by MMI.
 
     11.6  Indemnification.  Notwithstanding anything to the contrary set forth
in Article X hereof, in connection with the Registrable Securities being
included in a registration statement under this Article XI:
 
          (a) To the extent permitted by law, MMI will indemnify and hold
     harmless MEDIQ and each Person, if any, who controls MEDIQ within the
     meaning of the 1933 Act, against any losses, claims, damages or liabilities
     to which they may become subject under the 1933 Act insofar as such losses,
     claims, damages or liabilities (or actions in respect thereof) arise out of
     or are based on any untrue or alleged untrue statement of any material fact
     contained in such registration statement, including any preliminary
     prospectus or final prospectus contained therein or any amendments
     or supplements thereto, or arise out of or are based upon the omission
     or alleged omission to state therein a material fact required to be
     therein, or necessary to make the statements therein not misleading; 
     and will reimburse MEDIQ or such controlling person of MEDIQ for any 
     legal or other expenses reasonably incurred by them in connection 
     with investigating or defending any such loss, claim, damage, 
     liability, or action; provided, however, that the indemnity 
     agreement contained in this paragraph 11.6(a) shall not (i) apply
     to amounts paid in settlement of any such loss, claim, damage, liability,
     or action if such settlement is effected without the consent of MMI (which
     consent shall not be unreasonably withheld); or (ii) apply to any such case
     for any such loss, claim, damage, liability, or action to the extent that
     it arises out of or is based upon an untrue statement or alleged untrue
     statement or omission or alleged omission made in connection with such
     registration statement, preliminary prospectus, final prospectus, or
     amendments or supplements thereto, in reliance upon and in conformity with
     written information furnished by MEDIQ or such controlling person of MEDIQ
     for use in connection with such registration.
 
          (b) To the extent permitted by law, MEDIQ will indemnify and hold
     harmless MMI, each of its directors, each of its officers who have signed
     the registration statement, each Person, if any, who controls MMI within
     the meaning of the 1933 Act, and each agent for MMI against any losses,
     claims, damages or liabilities to which MMI or any such director, officer,
     controlling person or agent of MMI may become subject under the 1933 Act
     insofar as such losses, claims, damages or liabilities arise out of or are
     based upon any untrue statement or alleged untrue statement of any material
     fact contained in such registration statement, including any preliminary
     prospectus or final prospectus contained therein or any amendments or
     supplements thereto, or arise out of or are based upon the omission or
     alleged omission to state therein a material fact required to be stated
     therein or necessary to make the statements therein not misleading, in 
     each case to the extent, but only to the extent, that
     such untrue statement or alleged untrue statement or omission or alleged
     omission was made in such registration statement, preliminary or final
     prospectus, or amendments or supplements thereto, in reliance upon and in
     conformity with information furnished by MEDIQ for use in connection with
     such registration; and MEDIQ will reimburse any legal or other expenses 
     reasonably incurred by MMI or any such director, officer, controlling 
     person or agent of MMI in connection with investigating or defending any 
     such loss, claim, damage, liability, or action; provided, however, that 
     the indemnity agreement contained in this paragraph 11.6(b) shall not 
     apply to amounts paid in settlement of any such loss, claim, damage, 
     liability, or action if such settlement is effected without the consent of
     MEDIQ (which consent shall not be unreasonably withheld).  This indemnity
     will be in addition to any liability which MEDIQ may otherwise have.
 
          (c) Any Person entitled to indemnification hereunder will:  (i) give
     notice to the indemnifying party of any claim with respect to which it
     seeks indemnification; and (ii) unless in such indemnified party's
     reasonable judgment a conflict of interest between such indemnified and
     indemnifying parties may exist with respect to such claim, permit such
     indemnifying party to assume the defense of such claim with counsel
     reasonably satisfactory to the indemnified party.  If such defense is
     assumed, the indemnifying party will not be subject to any liability for
     any settlement made without its consent (but such consent will not be
     unreasonably withheld).  An indemnifying party who is not entitled to, or
     elects not to, assume the defense of a claim will not be obligated to pay
     the fees and expenses of more than one counsel for all parties indemnified
     by such indemnifying party with respect to such claim, unless in the
     reasonable judgment of any indemnified party a conflict of interest may
     exist between such indemnified party and any other such indemnified parties
     with respect to such claim.  The failure to notify an indemnifying party of
     the commencement of any such action, if prejudicial to its ability to
     defend such action, shall relieve such indemnifying party of any liability
     to the indemnified party under this paragraph, but the omission to notify
     the indemnifying party will not relieve him of any liability that he may
     have to any indemnified party otherwise than under this paragraph.
 
     11.7  Transfer of Registration Rights.  The registration rights of MEDIQ
under this Article XI shall not be transferred to any transferee who acquires
any shares of the Registrable Securities without the prior written consent of
MMI which may be withheld for any reason or no reason at all, provided, however,
that the registration rights of MEDIQ under this Article XI may be transferred
to one transferee who acquires all the shares of Registrable Securities in a
transaction where MEDIQ is selling all of its outstanding capital stock or
substantially all of its assets or where MEDIQ is merged into another
corporation and is not the surviving entity with the prior written consent of
MMI which shall not be unreasonably withheld.
 
                                 ARTICLE XII

                                 TERMINATION
 
     12.1  Termination by Mutual Consent.  Notwithstanding approval of the
Merger by MMI, MMI Sub, MEDIQ or MEDIQ Sub, or their respective stockholders,
this Agreement may be terminated (i) at any time prior to the Closing by written
consent of MMI and MEDIQ or (ii) by either MMI or MEDIQ if the Closing does 
not occur within 120 days of the date of this Agreement provided that no MMI 
Party as to MMI and no MEDIQ Party as to MEDIQ is in breach of any of its 
representations, warranties, consents or agreements contained herein.
 
     12.2  Termination by MMI.  MMI may terminate this Agreement at any time
prior to the Closing by delivery of written notice to MEDIQ if: (a) MMI
determines in the exercise of its reasonable judgment that the pendency of any
lawsuit or the institution or threat of any governmental or administrative
action, investigation or inquiry which questions the validity or the legality of
the transactions contemplated hereby or which seeks to prevent, restrain, change
or obtain damages in respect of such transactions, makes it inadvisable to
consummate the transactions contemplated hereby, notwithstanding that such
lawsuit, action, investigation or inquiry may be deemed to be without merit; (b)
MEDIQ or MEDIQ Sub have breached or violated this Agreement in any material
respect and, if such breach or violation is curable, has failed to cure such
violations within 10 days of receiving written notice thereof.
 
     12.3  Termination by MEDIQ.  MEDIQ may terminate this Agreement at any time
prior to the Closing by delivery of written notice to MMI if: (a) MEDIQ
determines in the exercise of its reasonable judgment that the pendency of any
lawsuit or the institution or threat of any governmental or administrative
action, investigation or inquiry which questions the validity or the legality of
the transactions contemplated hereby or which seeks to prevent, restrain, change
or obtain damages in respect of such transactions, makes it inadvisable to
consummate the transactions contemplated hereby, notwithstanding that such
lawsuit, action, investigation or inquiry may be deemed to be without merit; (b)
MMI or MMI Sub has breached or violated this Agreement in any material respect
and, if such breach or violation is curable, has failed to cure such violations
within 10 days of receiving written notice thereof; or (c) any representation or
warranty made by MMI or MMI Sub is false or inaccurate in any material respect
or there is any material misrepresentation or omission by either MMI or MMI Sub;
or (d) the average of the daily closing prices for 10 consecutive trading days
of the MMI Common Stock between the date of this Agreement and the second day
preceding the Closing falls below $4.00 (a 'Stock Price Default') provided MEDIQ
delivers written notice of its election to terminate within 10 business days of
the occurrence of a Stock Price Default.  For purposes of this Section 12.3, the
closing price for each day shall be the last such reported sales price, or, in
case no such reported sale takes place on such day, the average of the closing
bid and asked prices for such day of the MMI Common Stock in the over-the
counter market as reported by the Nasdaq National Market System or any
comparable system.
 
     12.4  Effect of Termination.  In the event of termination as provided
above, all parties hereto shall bear their own costs associated with this
Agreement and all transactions mentioned herein and there shall be no obligation
on the part of either party's officers, directors or share/stockholders;
provided, that (a) Sections 13.5 (publicity), 13.9 (each party to bear own
costs), 13.10 (confidentiality) and 13.11 (attorneys' fees) shall survive such
termination and continue in full force and effect and (b) nothing herein will
relieve any party from liability for any breach of this Agreement prior to such
termination.

                     EXHIBIT A -- Form of Warrant Agreement
 
                                WARRANT AGREEMENT
 
     This WARRANT AGREEMENT (the 'Agreement') is made as of [__________], 1994
between MMI Medical, Inc., a California corporation ('MMI'), and MEDIQ
Incorporated, a Delaware corporation ('MEDIQ').
 
                                   RECITALS
 
     WHEREAS, in connection with that certain Agreement and Plan of
Reorganization among MMI, MMI Acquisition Subsidiary, Inc., MEDIQ and MEDIQ
Equipment and Maintenance Services, Inc. dated [______________], 1994 (the
'Reorganization Agreement'), MMI shall issue to MEDIQ (i) 2,050,000 shares (the
'MMI Shares') of $0.01 par value common stock of MMI (the 'MMI Common Stock')
and (ii) one warrant (the 'Warrant') entitling MEDIQ to purchase an aggregate of
325,000 shares of MMI Common Stock (the shares of MMI Common Stock issued upon
exercise of the Warrant are referred to herein as the 'Warrant Shares'); and

     WHEREAS, in connection with the Reorganization Agreement, MMI and MEDIQ
have agreed to enter into this Agreement.
 
     NOW, THEREFORE, in consideration of the premises and the mutual agreements
set forth herein and in the Reorganization Agreement, the parties hereto agree
as follows:
 
                                   ARTICLE I
 
                      ISSUANCE AND DELIVERY OF THE WARRANT
 
     1.01.  Issuance of the Warrant.  Subject to the Closing (as defined and as
such other capitalized terms used herein without definition are defined in the
Reorganization Agreement) having occurred MMI will issue and deliver the Warrant
to MEDIQ on the Closing Date.  The Warrant shall be substantially in the form of
Exhibit 1 attached hereto. The Warrant shall be dated the Closing Date, and
shall be signed on behalf of MMI by its President or a Vice President under its
corporate seal reproduced thereon and attested by its Secretary or an Assistant
Secretary.

                                 ARTICLE II
 
                     DURATION AND EXERCISE OF THE WARRANT
 
     2.01.  Duration of Warrant.  The Warrant may be exercised on or after the
business day following the Closing and prior to the close of business on the
fourth anniversary thereof, except as otherwise provided in Article IV hereof.
 
     2.02.  Terms of Exercise.  The Warrant shall entitle the holder thereof to
purchase the number of shares of MMI Common Stock stated therein, adjusted as
provided in Article III, upon payment of $6.25 per share, adjusted as provided
in Article III.  Such price, as in effect from time to time as provided in
Article III, is referred to herein as the 'Exercise Price.'
 
     2.03.  Exercise of the Warrant.
 
          (a) The Warrant shall be exercised in whole or in part by surrendering
     it, together with a subscription in the form appearing on the reverse side
     thereof duly executed and accompanied by a certified or official bank 
     check in payment of the Exercise Price.
 
          (b) In lieu of paying the Exercise Price to MMI with respect to the
     exercise of the Warrant into Warrant Shares as required by Section 2.03(a)
     hereof, the holder may pay all or any portion of the Exercise Price with 
     respect to such Warrant Shares by surrendering the Warrant to MMI to the 
     extent representing Warrant Shares equal to (A) the aggregate Exercise 
     Price of the Warrant Shares so surrendered, divided by (B) the excess of 
     (1) the current market price per share of MMI Common Stock (determined as
     provided in Section 3.01(d) below) on the business day immediately 
     preceding the date on which the Warrant is delivered to the Company for 
     exercise, over (2) the Exercise Price per share in effect at such time.
     Any Warrant surrendered pursuant to this Section 2.03(b) shall be
     accompanied by a duly completed and executed Assignment in such form as 
     attached to the Warrant set forth in Schedule 1 attached hereto assigning
     the right to purchase surrendered Warrant Shares to the Company.
 
          (c) The Warrant shall be exercisable during the period provided in
     Section 2.01 hereof at any time in whole or from time to time in part.  As
     soon as practicable after the Warrant has been so exercised, MMI shall
     issue and deliver or cause to be delivered to, or upon the order of, the
     holder of such Warrant, in such name or names as may be directed by such
     holder, a certificate or certificates for the number of full Warrant Shares
     to which such holder is entitled, and cash as provided in Section 3.09 in
     respect of any remaining fractional interest in a Warrant Share and, if
     such Warrant shall not have been exercised in full, a new Warrant for the
     number of full shares of MMI Common Stock as to which such Warrant shall
     not have been exercised.  Any Warrant so surrendered shall be cancelled by
     or on behalf of MMI.
 
     2.04.  Common Stock Issued upon Exercise of the Warrant.
 
          (a) All Warrant Shares, when issued in accordance with the terms
     hereof, shall be duly authorized, validly issued, fully paid and
     nonassessable, and shall be free and clear of all Encumbrances.  MMI shall
     pay all documentary stamp taxes, if any, attributable to the initial
     issuance of Warrant Shares.  MMI shall not be required, however, to pay any
     tax imposed in connection with any transfer involved in the issue of the
     Warrant Shares in a name other than that of the holder of the Warrant who
     shall have exercised the same.  In such case, MMI shall not be required to
     issue any certificate for Warrant Shares until the person or persons
     requesting the same shall have paid to MMI the amount of any such tax or
     shall have established to MMI's reasonable satisfaction that the tax has
     been paid or that no tax is due.
 
          (b) Irrespective of the date of issue of certificates for any Warrant
     Shares, each person in whose name any certificate is issued shall be deemed
     to have become the holder of record of the Warrant Shares represented
     thereby on the date on which the Warrant was exercised and payment of the
     Exercise Price was tendered as provided in Section 2.03.
 
                                  ARTICLE III
 
                           ANTI-DILUTION PROVISIONS
 
     3.01.  Adjustment of Exercise Price and Number of Warrant Shares.  The
number of Warrant Shares purchasable upon the exercise of each Warrant
and the Exercise Price shall be subject to adjustment as follows:
 
          (a) If MMI shall (i) pay a dividend in shares of MMI Common Stock or
     make a distribution in shares of MMI Common Stock, (ii) subdivide its
     outstanding shares of MMI Common Stock, (iii) combine its outstanding
     shares of MMI Common Stock or (iv) issue by reclassification of its shares
     of MMI Common Stock other securities of MMI (including any such
     reclassification in connection with a consolidation or merger in which MMI
     is the surviving corporation), the number of Warrant Shares purchasable
     upon exercise of each Warrant immediately prior thereto shall be adjusted
     so that the holder of each Warrant shall be entitled to receive the kind
     and number of Warrant Shares or other securities of MMI which the holder
     would have owned or would have been entitled to receive after the happening
     of any of the events described above, had such Warrant been exercised
     immediately prior to the happening of such event or any record date with
     respect thereto.  An adjustment made pursuant to this paragraph (a) shall
     become effective immediately after the effective date of such event
     retroactive to the record date, if any, for such event.  Such adjustment
     shall be made successively whenever any event listed above shall occur.
 
          (b) If MMI shall issue rights, options or warrants to all holders of
     the outstanding MMI Common Stock, without any charge to such holders,
     entitling them (for a period within 45 days after the record date mentioned
     below) to subscribe for or purchase shares of MMI Common Stock at a price
     per share which is lower at the record date mentioned below than the then
     current market price per share of MMI Common Stock (as defined in paragraph
     (d) below), the number of Warrant Shares thereafter purchasable upon the
     exercise of each Warrant shall be determined by multiplying the number of
     Warrant Shares theretofore purchasable upon exercise of each Warrant by a
     fraction, the numerator of which shall be the number of shares of MMI
     Common Stock outstanding on the date of issuance of such rights, options or
     warrants plus the number of additional shares of MMI Common Stock offered
     for subscription or purchase, and the denominator of which shall be the
     number of shares of MMI Common Stock outstanding on the date of issuance of
     such rights, options or warrants plus the number of shares which the
     aggregate offering price of the total number of shares of MMI Common Stock
     so offered would purchase at the current market price per share of MMI
     Common Stock at such record date.  Such adjustment shall be made whenever
     such rights, options or warrants are issued, and shall become effective
     immediately after the record date for the determination of stockholders
     entitled to receive such rights, options and warrants.
 
          (c) If MMI shall distribute to all holders of shares of MMI Common
     Stock (including any such distribution made in connection with a
     consolidation or merger in which MMI is the surviving corporation)
     evidences of its indebtedness or assets (excluding cash dividends or
     distributions payable out of consolidated earnings or earned surplus and
     dividends or distributions referred to in paragraph (a) above or in the
     paragraph immediately following this paragraph) or rights, options or 
     warrants, or convertible or exchangeable securities containing the right 
     to subscribe for or purchase shares of MMI Common Stock (excluding those 
     referred to in paragraph (b) above) then, in each case, the number of 
     Warrant Shares thereafter purchasable upon the exercise of each Warrant 
     shall be determined by multiplying the number of Warrant Shares 
     theretofore purchasable upon the exercise of each Warrant by a fraction, 
     the numerator of which shall be the then current market price per share of
     MMI Common Stock (as defined in paragraph (d) below) on the date of such 
     distribution, and the denominator of which shall be the then current 
     market price per share of MMI Common Stock (as defined in paragraph (d)
     below), less the then fair value (as determined in good faith by the 
     board of directors of MMI, whose determination shall be conclusive
     if made in good faith) of the portion of the assets or evidences of 
     indebtedness so distributed or of such subscription rights, options or 
     warrants, or of such convertible or exchangeable securities applicable to
     one share of MMI Common Stock.  Such adjustment shall be made whenever 
     any such distribution is made, and shall become effective on the date of 
     distribution retroactive to the record date for the determination of 
     shareholders entitled to receive such distributions.
 
          If MMI shall make a distribution to all holders of the shares of MMI 
     Common Stock of stock of a subsidiary or securities convertible into or 
     exercisable for such stock, then in lieu of an adjustment in the number of
     Warrant Shares purchasable upon the exercise of each Warrant, the holder 
     of each Warrant, upon the exercise thereof at any time after such 
     distribution, shall be entitled to receive from MMI, such subsidiary or 
     both, as MMI shall determine, the stock or other securities to which such
     holder would have been entitled if such holder had exercised such Warrant
     immediately prior thereto, all subject to further adjustment as provided 
     in this Section 3.01; provided, however, that no adjustment in respect of
     dividends or interest on such stock or other securities shall be made
     during the term of a Warrant or upon the exercise of a Warrant.
 
          (d) For the purpose of any computation under (i) Section 2.03(b), (ii)
     paragraphs (b) or (c) of this Section 3.01 and (iii) Section 3.05, the
     current market price per share of MMI Common Stock at any date shall be the
     average of the daily closing prices for 20 consecutive trading days
     commencing 30 trading days before the date of such computation. The closing
     price for each day shall be the last such reported sales price regular way
     or, in case no such reported sale takes place on such day, the average of
     the closing bid and asked prices regular way for such day, in each case on
     the principal national securities exchange on which the shares of MMI
     Common Stock are listed or admitted to trading or, if not listed or
     admitted to trading, the closing sale price, or if none available, the
     average of the closing bid and asked prices of the MMI Common Stock in the
     over-the-counter market as reported by the NASDAQ National Market System 
     or any comparable system or if not approved for quotation on the NASDAQ 
     National Market System or any comparable system, the average of the 
     closing bid and asked prices as furnished by two members of the National 
     Association of Securities Dealers, Inc. selected from time to time by MMI
     for that purpose.
 
          (e) No adjustment in the number of Warrant Shares purchasable
     hereunder shall be required unless such adjustment would require an
     increase or decrease of at least one percent (1%) in the number of Warrant
     Shares purchasable upon the exercise of each Warrant; provided, however,
     that any adjustments which by reason of this paragraph (e) are not required
     to be made shall be carried forward and taken into account in any
     subsequent adjustment.  All calculations shall be made to the nearest
     one-thousandth of a share.
 
          (f) Whenever the number of Warrant Shares purchasable upon the
     exercise of each Warrant is adjusted, as herein provided, the Exercise
     Price payable upon exercise of each Warrant shall be adjusted by
     multiplying the Exercise Price immediately prior to such adjustment by a
     fraction, the numerator of which shall be the number of Warrant Shares
     purchasable upon the exercise of each Warrant immediately prior to such
     adjustment, and the denominator of which shall be the number of Warrant
     Shares purchasable immediately thereafter.
 
          (g) No adjustment in the number of Warrant Shares purchasable upon the
     exercise of each Warrant need be made under paragraphs (b) and (c) if MMI
     issues or distributes to each holder of Warrants the rights, option,
     warrant, or convertible or exchangeable securities, or evidences of
     indebtedness or assets referred to in those paragraphs which each holder of
     Warrants would have been entitled to receive had the Warrants been
     exercised prior to the happening of such event or the record date with
     respect thereto.  No adjustment need be made for a change in the par value
     of the Warrant Shares.
 
          (h) In the event that at any time, as a result of an adjustment made
     pursuant to paragraph (a) above, the holders of Warrant shall become
     entitled to purchase any securities of MMI other than shares of MMI Common
     Stock, thereafter the number of such other shares so purchasable upon
     exercise of each Warrant and the Exercise Price of such shares shall be
     subject to adjustment from time to time in a manner and on terms as nearly
     equivalent as practicable to the provisions with respect to the Warrant
     Shares contained in paragraphs (a) through (g), inclusive, above, and the
     provisions of Sections 2.01 (duration), 2.02 (terms of exercise), 3.02
     (notice) and 3.03 (no adjustment for dividends), with respect to the
     Warrant Shares, shall apply on like terms to such other securities.

          (i) Upon the expiration of any rights, options, warrants or conversion
     or exchange privileges, if any thereof shall not have been exercised, the
     Warrant Price and the number of shares of MMI Common Stock purchasable 
     upon the exercise of each Warrant shall, upon such expiration, be 
     readjusted and shall thereafter be such as it would have been had it been
     originally adjusted (or had the original adjustment not been required, as
     the case may be) as if (i) the only shares of MMI Common Stock so issued 
     were the shares of MMI Common Stock, if any, actually issued or sold upon
     the exercise of such rights, options, warrants or conversion or exchange 
     rights and (ii) such shares of MMI Common Stock, if any, were issued or 
     sold for the consideration actually received by MMI upon such exercise 
     plus the aggregate consideration, if any, actually received by MMI for the
     issuance, sale or grant of all such rights, options, warrants or 
     conversion or exchange rights whether or not exercised; provided,
     however, that no such readjustment shall have the effect of increasing the
     Warrant Price or decreasing the number of shares of MMI Common Stock 
     purchasable upon the exercise of each Warrant by an amount in excess of 
     the amount of the adjustment initially made in respect to the issuance, 
     sale or grant of such rights, options, warrants or conversion or exchange
     rights.
 
     3.02.  Notice of Change in Shares Issuable, etc.  Whenever the securities
issuable or deliverable in exchange for Warrant is changed pursuant to this
Article III, MMI promptly shall prepare a certificate executed by its chief
financial officer, setting forth a brief statement of the facts requiring the
change and specifying the effective date of such change and the number or amount
of, and describing the shares or other securities issuable or deliverable in
exchange for, each Warrant as so changed. MMI shall mail such a notice to each
holder of Warrant at the address registered with MMI.  Failure to file such
statement or to publish such notice, or any defect in such statement or notice,
shall not affect the legality or validity of any such change.
 
     3.03.  No Adjustment for Dividends.  Except as provided in Section 3.01, no
adjustment in respect of any dividends shall be made during the term of a
Warrant or upon the exercise of a Warrant.
 
     3.04.  Form of Warrant.  The form of Warrant need not be changed because of
any change in the amounts or nature of securities issuable or deliverable
pursuant to this Article III, and Warrants issued after such change may state
the same number of shares issuable in exchange for the Warrant as is stated in
the Warrant initially issued pursuant to this Agreement.  However, MMI at any
time, in its sole discretion (which shall be conclusive), may change the form of
Warrant to reflect any such change in the amounts or nature of securities
issuable or deliverable upon exercise, provided such change in form does not
otherwise affect the substance thereof; and any Warrant thereafter issued or
countersigned, whether in exchange or substitution for an outstanding Warrant or
otherwise, may be in the form as so changed.
 
     3.05.  Cash in Lieu of Fractional Shares.  MMI shall not be required to
issue fractional shares of MMI Common Stock upon exercise of Warrants.  If, by
reason of any change be made pursuant to this Article III, the holder of any
Warrant would be entitled, upon the exercise of any rights evidenced thereby, to
receive a fractional interest in a share, MMI, upon such exercise, shall
purchase such fractional interest for an amount in cash equal to the current
market price per share of MMI Common Stock (as defined in Section 3.01(d)) on
the trading day immediately preceding the date the Warrant is presented for
exercise multiplied by such fractional interest.
 
                                  ARTICLE IV
 
       PRESERVATION OF PURCHASE RIGHTS UPON MERGER, CONSOLIDATION, ETC.
 
     In case of any consolidation of MMI with or merger of MMI into another
corporation or in case of any sale, transfer or lease to another corporation of
all or substantially all the property of MMI, MMI or such surviving or
purchasing corporation, as the case may be, shall execute with each holder of
Warrants an agreement that each holder shall have the right thereafter upon
payment of the Exercise Price in effect immediately prior to such action to
purchase upon exercise of each Warrant the kind and amount of shares and other
securities, cash and property which the holder would have owned or would have
been entitled to receive after the happening of such consolidation, merger,
sale, transfer or lease had such Warrant been exercised immediately prior to
such action; provided, however, that no adjustment in respect of dividends,
interest or other income on or from such shares or other securities, cash and
property shall be made during the term of a Warrant or upon the exercise of a
Warrant.  Such agreement shall provide for adjustments, which shall be as nearly
equivalent as may be practicable to the adjustments provided for in Article 
III.  The provisions of this Article IV shall similarly apply to successive 
consolidations, mergers, sales, transfers or leases.
 
                                   ARTICLE V
 
              OTHER PROVISIONS FOR PROTECTION OF WARRANT HOLDERS
 
     5.01.  Reservation of Shares.  MMI at all times shall reserve and keep
available such number of shares of its authorized but unissued MMI Common Stock
as from time to time shall be sufficient to permit the exercise of all
outstanding Warrants.  If at any time the number of authorized but unissued
shares of MMI Common Stock shall not be sufficient for such purpose, MMI will
take such action as, in the opinion of its counsel, may be necessary to 
increase its authorized but unissued MMI Common Stock to such number of shares
as shall be sufficient for such purpose.  Prior to the issuance of any Warrant
Shares, MMI shall secure the listing of such Warrant Shares upon any securities
exchange upon which shares of Common Stock are then listed, if any.
 
     5.02.  Lost and Misplaced Warrant Certificates.  If any Warrant becomes
lost, stolen, mutilated or destroyed, MMI, on such terms as to indemnity or
otherwise as it may in its discretion impose, will issue a new Warrant of like
denomination, tenor and date as the Warrant so lost, stolen, mutilated or
destroyed.  Any such new Warrant shall constitute an original contractual
obligation of MMI, whether or not the allegedly lost, stolen, mutilated or
destroyed Warrant shall at any time be enforceable by anyone.
 
     5.03.  Enforcement of Warrant Rights.  All rights of action are vested in
the respective holders of the Warrant.  Any holder of any Warrant may, in his
own behalf and for his own benefit, enforce, and may institute and maintain any
suit, action or proceeding against MMI suitable to enforce, or otherwise in
respect of, his right to exercise his Warrant for the purchase of the number of
Warrant Shares issuable or deliverable in exchange therefor, in the manner
provided in the Warrant and in this Agreement.
 
     5.04.  Notice of Distributions.  Whenever MMI shall authorize the payment
or distribution of a cash or other dividend to all holders of the MMI Common
Stock which does not require an adjustment to the Warrant pursuant to
Subsections (a), (b) or (c) of Section 3.01 hereof, then MMI will cause to be
mailed to the holder of the Warrant by first class mail addressed to such holder
at the address appearing in the records of MMI, at least 10 days before the
applicable record date with respect to such dividend or distribution, a notice
stating (A) the date on which record is to be taken for the purpose of such
dividend or distribution, or, if a record is not to be taken, the date as of
which the holders of MMI Common Stock of record to be entitled to such dividend
or distribution are to be determined and (B) a brief description of the kind and
aggregate amount of such dividend or distribution, including, if available, the
amount thereof on a per share of MMI Common Stock basis.

 
                                ARTICLE VI
 
                    TRANSFER AND OWNERSHIP OF WARRANT
 
     6.01.  Negotiability and Ownership.  Any Warrant issued hereunder shall not
be sold, transferred, assigned or hypothecated or in any manner transferred by
MEDIQ except in compliance with the Securities Act of 1933, as amended, and any
applicable state securities laws.  Any attempt to sell, transfer, assign or
hypothecate in contravention of this Section shall be null and void.
 
     6.02.  Exchange of Warrant.  Upon the issuance and prior to the expiration
thereof, one or more Warrant may be surrendered at the office MMI for exchange
and, upon cancellation thereof, one or more new Warrant shall be issued as
requested by the holder of the cancelled Warrant or Warrants for the same
aggregate number of shares as were issuable in exchange for the Warrant or
Warrants so cancelled.
 
                                  ARTICLE VII
 
                           MISCELLANEOUS PROVISIONS
 
     7.01.  Applicable Law.  This Agreement and the Warrant shall be governed by

regard to the choice of law rules thereof.

     7.04.  Benefits of this Agreement. Nothing in this Agreement shall be
construed to give to any person or corporation other than MMI and the holders of
Warrants or Warrant Shares any legal or equitable right, remedy or claim under
this Agreement.  This Agreement shall be for the sole and exclusive benefit of
MMI and the holders of Warrants or Warrant Shares.
 
     7.05.  Headings.  The section headings herein are for convenience only

hereof.
 
     7.06.  Counterparts.  This Agreement may be executed in any number of

                          TERMINATION AND AMENDMENT
 
     8.01.  Termination upon Failure of Closing. Notwithstanding anything herein
to the contrary, this Agreement shall terminate and all Warrant granted

shall have been terminated prior to the Closing thereof.

                EXHIBIT F -- Form of Noncompetition Agreement
 
                         MEDIQ NONCOMPETITION AGREEMENT
 
     THIS NONCOMPETITION AGREEMENT (the 'Agreement') is made and entered into as

     WHEREAS, MEDIQ has this date conveyed to MMI, all of the issued and
outstanding capital stock of MEDIQ Sub pursuant to that certain Agreement and
Plan of Reorganization among MMI, MMI Acquisition Subsidiary, Inc. ('MMI Sub'),
MEDIQ Sub and MEDIQ (the 'Reorganization Agreement');
 
     WHEREAS, upon the consummation of the transactions contemplated in the
Reorganization Agreement, MMI Sub merged with and into MEDIQ Sub with MMI
holding all of the outstanding capital stock of MEDIQ Sub as the 'surviving
corporation' (as defined in the Reorganization Agreement);
 
     WHEREAS, the business of MEDIQ Sub as currently conducted, including
without limitation the business of providing repair and maintenance services,

scanners, nuclear medicine equipment, magnetic resonance imaging
systems and other diagnostic imaging equipment for hospitals and mobile and
fixed-site operators (the 'Business') has heretofore been conducted in the
Territory (as defined below);
 
     WHEREAS, MMI through MEDIQ Sub intends to carry on the Business;
 
     WHEREAS, pursuant to Section 7.8 of the Reorganization Agreement, MEDIQ has
agreed to enter into a noncompetition agreement in favor of MMI and the
surviving corporation;
 
     WHEREAS, if MEDIQ were to compete with MMI's operation of the Business in
the Territory through the surviving corporation other than as permitted herein,
MMI could be deprived of the benefit of any reputation or goodwill of the
surviving corporation as may exist after the date hereof; and
 
     WHEREAS, the covenants provided herein are material, significant and
essential to effecting the transactions contemplated by the Reorganization
Agreement, and the Noncompetition Shares (defined below) and the consideration
under the Reorganization Agreement has been transferred from MMI to MEDIQ in
exchange for such covenants.
 
                                   AGREEMENT
 
     NOW, THEREFORE, in consideration of the sum of 20,000 shares (the
'Noncompetition Shares') of MMI Common Stock, as that term is defined in the
Reorganization Agreement, and the premises and of the respective representations
and warranties contained herein and the respective covenants and agreements
contained in this Agreement and the Reorganization Agreement and to induce MMI
to perform its obligations thereunder, the parties hereto agree as follows:
 
     1.  Term.  The term of this Agreement shall commence on the date of the
Closing, as that term is defined in the Reorganization Agreement, and shall
terminate on the fifth anniversary of the date of the Closing,
except that the covenant set forth in Section 2(c) shall terminate on the third
anniversary of the date of the Closing.
 
     2.  Covenant Not to Compete.  For the term of this Agreement, MEDIQ shall
not, directly or indirectly:
 
          (a) engage in the Business or any business competing with the
     Business;
 
          (b) have any interest in, own, manage, operate, control, be connected
     with as a stockholder (other than as a stockholder of less than one percent
     (1%) of the issued and outstanding stock of a publicly held corporation),
     joint venturer, officer, partner, employee or consultant, or otherwise
     engage or invest or participate in the Business or any business which shall
     compete with the Business conducted by the surviving corporation or any
     successor of the surviving corporation in the Territory; or
 
          (c) solicit any then current employee of the surviving corporation to
     leave the employ of the surviving corporation.
 
          (d) Notwithstanding the foregoing, MEDIQ shall not be restricted from
     repairing or maintaining (directly or indirectly through subsidiaries)
     nuclear medicine equipment in conjunction with MEDIQ Sub's business of
     providing nuclear medicine and ultrasound services, so long as MEDIQ does
     not bid for nuclear medicine equipment maintenance contracts currently held
     by MMI when such contracts are renewed.
 
     3.  Injunctive Relief.  The parties hereto agree that damages would be an
inadequate remedy for MMI or the surviving corporation in the event of breach or
threatened breach of this Agreement and thus, in any such event, MMI or the
surviving corporation may, either with or without pursuing any potential damage
remedies, immediately obtain and enforce an injunction prohibiting MEDIQ from
violating this Agreement.
 
     4.  Territory.  For purposes of this Agreement, 'Territory' means the
Business carried on by the surviving corporation in those counties in the
respective states listed on Schedule 1.
 
     5.  Enforceability.  It is the desire and intent of the parties hereto that
the provisions of this Agreement be enforced to the fullest extent permissible
under the laws and public policies of each jurisdiction in which enforcement is
sought.  Accordingly, if any provision of this Agreement shall be adjudicated to
be invalid or unenforceable, such provision, without any action on the part of
the parties hereto, shall be deemed amended to delete or to modify (including,
without limitation, a reduction in duration, geographical area or prohibited
business activities) the portion adjudicated to be invalid or unenforceable,
such deletion or modification to apply only with respect to the operation of
such provision in the particular jurisdiction in which such adjudication is
made, and such deletion or modification to be made only to the extent necessary
to cause the provision as amended to be valid and enforceable.
 
     6.  Noncompetition Shares.  As an inducement to MEDIQ to enter into this
Agreement, MMI represents and warrants that (a) the Noncompetition Shares which
are to be transferred to MEDIQ by MMI pursuant hereto are free and clear of any
and all Encumbrances (as defined in the Reorganization Agreement); (b) MMI has
the full right, power and authority to issue and transfer the Noncompetition
Shares to MEDIQ pursuant to the terms of this Agreement; and (c) the
Noncompetition Shares to be issued to MEDIQ  as contemplated hereunder are duly
authorized and, when issued pursuant to the terms of this Agreement, will be
duly authorized, validly issued, fully paid, non-assessable, not subject to any
preemptive or similar rights.
 
     7.  Amendment; Beneficiary; Termination.  This Agreement may be amended
only by a written instrument signed by each of the parties hereto.  Nothing in 
this Agreement, express or implied, is intended to confer upon any third person
any rights or remedies under or by reason of this Agreement.  This Agreement 
may be terminated only upon the written agreement of MMI, the surviving 
corporation and MEDIQ.  No waiver of any provision of this Agreement shall 
constitute a waiver of any other provision hereof (whether or not similar) nor
shall such waiver constitute a continuing waiver unless otherwise expressly 
provided.
 
     8.  Complete Understanding.  This Agreement constitutes the full and
complete understanding and agreement of the parties with respect to the subject
matter hereof and supersedes all prior and contemporaneous understandings and
agreements with respect to the subject matter hereof.

     respective Certificates of Incorporation or Bylaws, or, to the best of such
     counsel's knowledge, any judicial or governmental decree, order or judgment
     to which MEDIQ Sub is a party or to which either of MEDIQ or MEDIQ Sub.

     authorization, order, registration, qualification or filing of or with any
     court or any regulatory authority or other governmental body (other than
     the filing of the Certificate of Merger and other than consents or filings
     required by state and federal securities laws in connection with the
     issuance of MMI Common Stock) required for the consummation by MEDIQ or
     MEDIQ Sub of the transactions contemplated by this Agreement which has not
     been obtained or waived.
 
          (v) Upon the delivery and filing of the Certificate of Merger with the
