                              UNDERWRITING AGREEMENT

   Goldman, Sachs & Co.
   J.P. Morgan Securities Inc.
        As representatives of the
     several Underwriters named in the
     respective Pricing Agreements.
   c/o Goldman, Sachs & Co.
   85 Broad Street
   New York, New York 10004

   Dear Sirs: 

        From time to time Mallinckrodt Group Inc., a New York corporation (the
   "Company"), proposes to enter into one or more Pricing Agreements (each a
   "Pricing Agreement") in the form of Annex I hereto, with such additions and
   deletions as the parties thereto may determine, and, subject to the terms
   and conditions stated herein and therein, to issue and sell to the firms
   named in Schedule I to the applicable Pricing Agreement (such firms
   constituting the "Underwriters" with respect to such Pricing Agreement and
   the securities specified therein) certain of its debt securities (the
   "Securities") specified in Schedule II to such Pricing Agreement (with
   respect to such Pricing Agreement, the "Designated Securities"). 

        The terms and rights of any particular issuance of Designated
   Securities shall be as specified in the Pricing Agreement relating thereto
   and in or pursuant to the indenture (the "Indenture") identified in such
   Pricing Agreement. 


        1.   Particular sales of Designated Securities may be made from time
   to time to the Underwriters of such Securities, for whom the firms
   designated as representatives of the Underwriters of such Securities in the
   Pricing Agreement relating thereto will act as representatives (the
   "Representatives"). The term "Representatives" also refers to a single firm
   acting as sole representative of the Underwriters and to Underwriters who
   act without any firm being designated as their representative. This
   Underwriting Agreement shall not be construed as an obligation of the
   Company to sell any of the Securities or as an obligation of any of the
   Underwriters to purchase the Securities. The obligation of the Company to
   issue and sell any of the Securities and the obligation of any of the
   Underwriters to purchase any of the Securities shall be evidenced by the
   Pricing Agreement with respect to the Designated Securities specified
   therein. Each Pricing Agreement shall specify the aggregate principal
   amount of such Designated Securities, the initial public offering price of
   such Designated Securities, the purchase price to the Underwriters of such
   Designated Securities, the names of the Underwriters of such Designated
   Securities, the names of the Representatives of such Underwriters and the
   principal amount of such Designated Securities to be purchased by each
   Underwriter and shall set forth the date, time and manner of delivery of
   such Designated Securities and payment therefor. The Pricing Agreement
   shall also specify (to the extent not set forth in the Indenture and the
   registration statement and prospectus with respect thereto) the terms of
   such Designated Securities. A Pricing Agreement shall be in the form of an
   executed writing (which may be in counterparts), and may be evidenced by an
   exchange of telegraphic communications or any other rapid transmission
   device designed to produce a written record of communications transmitted.
   The obligations of the Underwriters under this Agreement and each Pricing
   Agreement shall be several and not joint. 

        2.   The Company represents and warrants to, and agrees with, each of
   the Underwriters that: 

        (a)  Two registration statements on Form S-3 (File No. 33-47081 and
   33-       ) in respect of the Securities have been filed with the
   Securities and Exchange Commission (the "Commission"); such registration
   statements as they may have been amended prior to their effectiveness and
   any post-effective amendment thereto filed on or prior to the date of this
   Agreement or the applicable Time of Delivery, each in the form heretofore
   delivered or to be delivered to the Representatives (for themselves and for
   each of the other underwriters), have been declared effective by the
   Commission in such form; no other document with respect to such
   registration statement or document incorporated by reference therein has
   heretofore been filed or transmitted for filing with the Commission (other
   than the prospectuses filed pursuant to Rule 424(b) of the rules and
   regulations of the Commission under the Securities Act of 1933, as amended
   (the "Act"), and such other documents listed in Annex III hereto, each in
   the form heretofore delivered to the Representatives); and no stop order
   suspending the effectiveness of either of the registration statements has
   been issued and no proceeding for that purpose has been initiated or
   threatened by the Commission (any preliminary prospectus (including, if
   applicable, any preliminary prospectus supplement) included in such
   registration statement or filed with the Commission pursuant to Rule
   424(a) of the Act, being hereinafter called a "Preliminary Prospectus". 
   The various parts of such registration statements, including all exhibits
   thereto and the documents incorporated by reference in the prospectus
   contained in each of the registration statements at the time such part of
   such registration statement became effective but excluding Form T-1, each
   as amended at the time such part of such registration statement became
   effective, being hereinafter collectively called the "Registration
   Statement"; the prospectus (including, if applicable, any prospectus
   supplement) relating to the Securities, in the form in which it has most
   recently been filed, or transmitted for filing, with the Commission on or


   prior to the date of this Agreement, being hereinafter called the
   "Prospectus"; any reference herein to any Preliminary Prospectus or the
   Prospectus shall be deemed to refer to and include the documents
   incorporated by reference therein pursuant to the applicable form under the
   Act, as of the date of such Preliminary Prospectus or Prospectus, as the
   case may be; any reference to any amendment or supplement to any
   Preliminary Prospectus or the Prospectus shall be deemed to refer to and
   include any documents filed after the date of such Preliminary Prospectus
   or Prospectus, as the case may be, under the Securities Exchange Act of
   1934, as amended (the "Exchange Act"), and incorporated by reference in
   such Preliminary Prospectus or Prospectus, as the case may be; any
   reference to any amendment to the Registration Statement shall be deemed to
   refer to and include any annual report of the Company filed pursuant to
   Section 13(a) or 15(d) of the Exchange Act after the effective date of the
   Registration Statement that is incorporated by reference in the
   Registration Statement; and any reference to the Prospectus as amended or
   supplemented shall be deemed to refer to the Prospectus as amended or
   supplemented in relation to the applicable Designated Securities in the
   form in which it is filed with the Commission pursuant to Rule 424(b) under
   the Act in accordance with Section 5(a) hereof, including any documents
   incorporated by reference therein as of the date of such filing); 

        (b)  The documents incorporated by reference in the Prospectus, when
   they became effective or were filed with the Commission, as the case may
   be, complied as to form in all material respects with the requirements of
   the Act or the Exchange Act, as applicable, and the rules and regulations
   of the Commission thereunder, and none of such documents, at such time of
   effectiveness or filing, as the case may be, contained an untrue statement
   of a material fact or omitted to state a material fact required to be
   stated therein or necessary to make the statements therein not misleading;
   and any further documents so filed and incorporated by reference in the
   Prospectus or any further amendment or supplement thereto, when such
   documents become effective or are filed with the Commission, as the case
   may be, will comply as to form in all material respects with the
   requirements of the Act or the Exchange Act, as applicable, and the rules
   and regulations of the Commission thereunder and, at such time of
   effectiveness or filing, as the case may be, will not contain an untrue
   statement of a material fact or omit to state a material fact required to
   be stated therein or necessary to make the statements therein not
   misleading; provided, however, that this representation and warranty shall
   not apply to any statements or omissions made in reliance upon and in
   conformity with information furnished in writing to the Company by an
   Underwriter of Designated Securities through the Representatives expressly
   for use in the Prospectus as amended or supplemented relating to such
   Designated Securities; 

        (c)  The Registration Statement and the Prospectus comply as to form,
   and any further amendments or supplements to the Registration Statement or
   the Prospectus will comply as to form, in all material respects with the
   requirements of the Act and the Trust Indenture Act of 1939, as amended
   (the "Trust Indenture Act") and the rules and regulations of the Commission
   thereunder and do not and will not, as of the applicable effective date as
   to the Registration Statement and any amendment thereto and as of the
   applicable filing date as to the Prospectus and any amendment or supplement
   thereto, contain an untrue statement of a material fact or omit to state a
   material fact required to be stated therein or necessary to make the
   statements therein not misleading; provided, however, that this
   representation and warranty shall not apply to any statements or omissions
   made in reliance upon and in conformity with information furnished in
   writing to the Company by an Underwriter of Designated Securities through
   the Representatives expressly for use in the Prospectus as amended or
   supplemented relating to such Designated Securities; 


        (d)  Neither the Company nor any of its subsidiaries has sustained
   since the date of the latest audited financial statements included or
   incorporated by reference in the Prospectus any material loss or
   interference with its business from fire, explosion, flood or other
   calamity, whether or not covered by insurance, or from any labor dispute or
   court or governmental action, order or decree, otherwise than as set forth
   or contemplated in the Prospectus; and, since the respective dates as of
   which information is given in the Registration Statement and the
   Prospectus, there has not been any change in the capital stock (except for
   subsequent issuances, if any, pursuant to reservations or agreements
   referred to in the Prospectus and except for subsequent repurchases by the
   Company not in excess of those disclosed in the Registration Statement as
   authorized as of the date the Registration Statement becomes effective) or
   any material change in long-term debt of the Company or any of its
   subsidiaries or any material adverse change in or affecting the general
   affairs, business prospects, management, financial position, stockholders'
   equity or results of operations of the Company and its subsidiaries,
   otherwise than as set forth or contemplated in the Prospectus; 

        (e)  The Company has been duly incorporated and is validly existing as

   incorporation, with corporate power and authority to own its properties and
   conduct its business as described in the Prospectus; 

        (f)  The Company has an authorized capitalization as set forth in the
   Prospectus (except for subsequent issuances, if any, pursuant to
   reservations or agreements referred to in the Prospectus and except for
   subsequent repurchases by the Company not in excess of those disclosed in
   the Registration Statement as authorized as of the date the Registration
   Statement becomes effective), and all of the issued shares of capital stock
   of the Company have been duly and validly authorized and issued and are
   fully paid and, except as may be otherwise provided by Section 630 of the
   New York Business Corporation Law, non-assessable; 

        (g)  The Securities have been duly authorized, and, when Designated
   Securities are issued, authenticated, delivered and paid for in accordance
   with the Indenture, this Agreement and the Pricing Agreement with respect
   to such Designated Securities, such Designated Securities will have been
   duly executed, authenticated, issued and delivered and will constitute
   valid and legally binding obligations of the Company (subject, as to
   enforcement, to bankruptcy, insolvency, reorganization and other laws of
   general applicability relating to or affecting creditors' rights and to
   general equity principles) entitled to the benefits provided by the
   Indenture, which will be substantially in the form filed as an exhibit to
   the Registration Statement; the Indenture has been duly authorized and duly
   qualified under the Trust Indenture Act and, at the Time of Delivery of
   such Designated Securities (as defined in Section 4 hereof), the Indenture
   will constitute a valid and legally binding instrument, enforceable in
   accordance with its terms, subject, as to enforcement, to bankruptcy,
   insolvency, reorganization and other laws of general applicability relating
   to or affecting creditors' rights and to general equity principles; and the
   Indenture conforms in all material respects and the Designated Securities
   will conform in all material respects, to the descriptions thereof
   contained in the Prospectus as amended or supplemented with respect to such
   Designated Securities;

      (h)    The issue and sale of the Securities and the compliance by the
   Company with all of the provisions of the Securities, the Indenture, this
   Agreement and any Pricing Agreement, and the consummation of the
   transactions herein and therein contemplated will not conflict with or
   result in a breach or violation of any of the terms or provisions of, or
   constitute a default under, any material indenture, mortgage, deed of
   trust, loan agreement or other agreement or instrument to which the Company


   is a party or by which the Company is bound or to which any of the property
   or assets of the Company is subject, nor will such action result in any
   violation of the provisions of the Certificate of Incorporation, as
   amended, or By-laws, as amended, of the Company or, to the best of the
   Company's knowledge, any statute or any order, rule or regulation of any
   court or governmental agency or body having jurisdiction over the Company
   or any of its properties; and no consent, approval, authorization, order,
   registration or qualification of or with any such court or governmental
   agency or body is required for the issue and sale of the Securities or the

   Agreement or any Pricing Agreement or the Indenture except such as have
   been, or will have been prior to the Time of Delivery, obtained under the
   Act and the Trust Indenture Act and such consents, approvals,
   authorizations, registrations or qualifications as may be required under
   state securities or Blue Sky laws in connection with the purchase and
   distribution of the Securities by the Underwriters; 

        (i)  Other than as set forth in the Prospectus, there are no legal or
   governmental proceedings pending to which the Company or any of its
   subsidiaries is a party or of which any property of the Company or any of
   its subsidiaries is the subject which, if determined adversely to the
   Company or any of its subsidiaries, would individually or in the aggregate
   have a material adverse effect on the current or future consolidated
   financial position, stockholders' equity or results of operations of the
   Company and its subsidiaries; and, to the best of the Company's knowledge,
   no such proceedings are threatened or contemplated by governmental
   authorities or threatened by others;

   such term is defined in Rule 1-02 of Regulation S-X ("Significant
   Subsidiaries") is in violation of its Certificate of Incorporation, as
   amended, or By-laws, as amended.  Neither the Company nor any of its
   subsidiaries is in default in the performance or observance of any
   obligation, covenant or condition contained in any material indenture,
   mortgage, deed of trust, loan agreement, lease or other agreement or
   instrument to which it is a party or by which it or any of its properties
   may be bound; and

        (m)  Ernst & Young LLP, who have certified certain financial
   statements of the Company and its subsidiaries, are independent public
   accountants as required by the Act and the rules and regulations of the
   Commission thereunder.

   the Company to the Representatives for the account of such Underwriter,
   against payment by such Underwriter or on its behalf of the purchase price
   therefor by certified or official bank check or checks, payable to the
   order of the Company in the funds specified in such Pricing Agreement, all
   at the place and time and date specified in such Pricing Agreement or at
   such other place and time and date as the Representatives and the Company
   may agree upon in writing, such time and date being herein called the "Time
   of Delivery" for such Securities. 

        5.   The Company agrees with each of the Underwriters of any
   Designated Securities: 

        (a)  To prepare the Prospectus as amended and supplemented in relation

   relating to the applicable Designated Securities or, if applicable, such
   earlier time as may be required by Rule 424(b); to make no further
   amendment or any supplement to the Registration Statement or Prospectus as

   Statement has been filed or becomes effective or any supplement to the
   Prospectus or any amended Prospectus has been filed with the Commission, of
   the issuance by the Commission of any stop order or of any order preventing
   or suspending the use of any prospectus relating to the Securities, of the
   suspension of the qualification of such Securities for offering or sale in
   any jurisdiction, of the initiation or threatening of any proceeding for
   any such purpose, or of any request by the Commission for the amending or
   supplementing of the Registration Statement or Prospectus or for additional
   information relating thereto or relating to matters discussed therein; and,
   in the event of the issuance of any such stop order or of any such order

   Representatives may request and to comply with such laws so as to permit
   the continuance of sales and dealings therein in such jurisdictions for as
   long as may be necessary to complete the distribution of such Securities,
   provided that in connection therewith the Company shall not be required to
   qualify as a foreign corporation or to file a general consent to service of
   process in any jurisdiction; 

        (c)  To furnish the Underwriters with copies of the Prospectus as
   amended or supplemented in such quantities as the Representatives may from
   time to time reasonably request, and, if the delivery of a prospectus is
   required at any time in connection with the offering or sale of the
   Securities and if at such time any event shall have occurred as a result of
   which the Prospectus as then amended or supplemented would include an
   untrue statement of a material fact or omit to state any material fact


   necessary in order to make the statements therein, in the light of the
   circumstances under which they were made when such Prospectus is delivered,
   not misleading, or, if for any other reason it shall be necessary during
   such same period to amend or supplement the Prospectus or to file under the
   Exchange Act any document incorporated by reference in the Prospectus in
   order to comply with the Act, the Exchange Act or the Trust Indenture Act,
   to notify the Representatives and upon their request to file such document
   and to prepare and furnish without charge to each Underwriter and to any
   dealer in securities as many copies as the Representatives may from time to
   time reasonably request of an amended Prospectus or a supplement to the
   Prospectus which will correct such statement or omission or effect such
   compliance; 

        (d)  To make generally available to its securityholders as soon as
   practicable, but in any event not later than eighteen months after the
   effective date of the Registration Statement (as defined in Rule 158(c)),

   audited) complying with Section 11(a) of the Act and the rules and
   regulations of the Commission thereunder (including at the option of the
   Company Rule 158); and 

        (e)  During the period beginning from the date of the Pricing
   Agreement for such Designated Securities and continuing to and including

   after the date of such Pricing Agreement not to offer, sell, contract to
   sell or otherwise dispose of any debt securities of the Company which
   mature more than one year after such Time of Delivery and which are
   substantially similar to such Designated Securities, without the prior
   written consent of the Representatives. 

        6.   The Company covenants and agrees with the several Underwriters
   that the Company will pay or cause to be paid the following: (i) the fees,
   disbursements and expenses of the Company's counsel and accountants in
   connection with the registration of the Securities under the Act and all
   other expenses in connection with the preparation, printing and filing of
   the Registration Statement, any Preliminary Prospectus and the Prospectus
   and amendments and supplements thereto and the mailing and delivering of
   copies thereof to the Underwriters and dealers; (ii) the cost of printing

   incident to the performance of its obligations hereunder which are not
   otherwise specifically provided for in this Section. It is understood,
   however, that, except as provided in this Section, Section 8 and Section 11

   Securities by them, and any advertising expenses connected with any offers
   they may make.

   equity principles; and the Indenture has been duly qualified under the
   Trust Indenture Act; 

        (vii)     The issue and sale of the Designated Securities and the
   compliance by the Company with all of the provisions of the Designated
   Securities, the Indenture, this Agreement and the Pricing Agreement with
   respect to the Designated Securities and the consummation of the
   transactions herein and therein contemplated will not conflict with or
   result in a breach or violation of any of the terms or provisions of, or
   constitute a default under, any material indenture, mortgage, deed of
   trust, loan agreement or other agreement or instrument known to such
   counsel to which the Company is a party or by which the Company is bound or
   to which any of the property or assets of the Company is subject, nor will
   such actions result in any violation of the provisions of the Certificate
   of Incorporation, as amended, or By-laws, as amended, of the Company or any
   statute or any order, rule or regulation known to such counsel of any court
   or governmental agency or body having jurisdiction over the Company or any
   of its properties; 

        (viii)    No consent, approval, authorization, order, registration or
   qualification of or with any court or governmental agency or body is
   required for the issue and sale of the Designated Securities or the
   consummation by the Company of the transactions contemplated by this
   Agreement or such Pricing Agreement or the Indenture, except such as have
   been obtained under the Act and the Trust Indenture Act and such consents,
   approvals, authorizations, registrations or qualifications as may be
   required under state securities or Blue Sky laws in connection with the
   purchase and distribution of the Designated Securities by the Underwriters;


        (ix) The documents incorporated by reference in the Prospectus as
   amended or supplemented (other than the financial statements and related
   schedules therein, as to which such counsel need express no opinion), when
   they became effective or were filed with the Commission, as the case may
   be, complied as to form in all material respects with the requirements of
   the Act or the Exchange Act, as applicable, and the rules and regulations
   of the Commission thereunder; and nothing has come to such counsel's
   attention that has caused them to believe that any of such documents (other


   than the financial statements and related schedules therein, as to which
   such counsel need express no belief), when they became effective or were so
   filed, as the case may be, contained, in the case of a registration
   statement which became effective under the Act, an untrue statement of a
   material fact or omitted to state a material fact required to be stated
   therein or necessary to make the statements therein not misleading, or in
   the case of other documents which were filed under the Act or the Exchange
   Act with the Commission, an untrue statement of a material fact or omitted
   to state a material fact necessary in order to make the statements therein,
   in the light of the circumstances under which they were made when such
   documents were so filed, not misleading; 

        (x)  The Registration Statement and the Prospectus as amended or
   supplemented and any further amendments and supplements thereto made by the
   Company prior to the Time of Delivery for the Designated Securities (other
   than the financial statements and related schedules therein, as to which
   such counsel need express no opinion) comply as to form in all material
   respects with the requirements of the Act and the Trust Indenture Act and
   the rules and regulations thereunder; nothing has come to such counsel's
   attention that has caused them to believe that, as of its effective date,
   the Registration Statement or any further amendment thereto made by the
   Company prior to the Time of Delivery (other than the financial statements
   and related schedules therein, as to which such counsel need express no
   belief) contained an untrue statement of a material fact or omitted to
   state a material fact required to be stated therein or necessary to make
   the statements therein not misleading or that, as of its date, the
   Prospectus as amended or supplemented or any further amendment or
   supplement thereto made by the Company prior to the Time of Delivery (other
   than the financial statements and related schedules therein, as to which
   such counsel need express no belief) contained an untrue statement of a
   material fact or omitted to state a material fact necessary to make the
   statements therein, in light of the circumstances in which they were made,
   not misleading or that, as of the Time of Delivery, either the Registration
   Statement or the Prospectus as amended or supplemented or any further
   amendment or supplement thereto made by the Company prior to the Time of
   Delivery (other than the financial statements and related schedules
   therein, as to which such counsel need express no belief) contains an
   untrue statement of a material fact or omits to state a material fact
   necessary to make the statements therein, in light of the circumstances in
   which they were made, not misleading;

        (xi) Such counsel does not know of any contracts or other documents of
   a character required to be filed as an exhibit to the Registration
   Statement or required to be incorporated by reference into the Prospectus
   as amended or supplemented or required to be described in the Registration
   Statement or the Prospectus as amended or supplemented which are not filed
   or incorporated by reference or described as required; 

        (xii)     The Company is not and, after giving effect to the offering
   and sale of the Securities, will not be an "investment company" or an
   entity "controlled" by an "investment company", as such terms are defined
   in the Investment Company Act; and

        (xiii)    Neither the Company nor any of its Significant Subsidiaries
   is in violation of its Certificate of Incorporation, as amended, or By-
   laws, as amended.  To the best of such counsel's knowledge, neither the
   Company nor any of its subsidiaries is in default in the performance or
   observance of any obligation, covenant or condition contained in any
   material indenture, mortgage, deed of trust, loan agreement, lease or other
   agreement or instrument to which it is a party or by which it or any of its
   properties may be bound. 


        (d)  On the date of the Pricing Agreement for such Designated
   Securities and at the Time of Delivery for such Designated Securities, the
   independent auditors of the Company who have certified the financial
   statements of the Company and its subsidiaries included or incorporated by
   reference in the Registration Statement shall have furnished to the
   Representatives a letter, dated the effective date of the Registration
   Statement or the date of the most recent report filed with the Commission
   containing financial statements and incorporated by reference in the
   Registration Statement, if the date of such report is later than such
   effective date, and a letter dated such Time of Delivery, respectively, to
   the effect set forth in Annex II hereto, and with respect to such letter
   dated such Time of Delivery, as to such other matters as the
   Representatives may reasonably request and in form and substance
   satisfactory to the Representatives; 

        (e)  (i) Neither the Company nor any of its subsidiaries shall have
   sustained since the date of the latest financial statements included or
   incorporated by reference in the Prospectus as amended or supplemented any
   material loss or interference with its business from fire, explosion, flood
   or other calamity, whether or not covered by insurance, or from any labor
   dispute or court or governmental action, order or decree, otherwise than as
   set forth or contemplated in the Prospectus as amended or supplemented, and
   (ii) since the respective dates as of which information is given in the
   Prospectus as amended or supplemented there shall not have been any change
   in the capital stock or long-term debt of the Company or any of its
   subsidiaries or any change in or affecting the general affairs, business
   prospects, management, financial position, stockholders' equity or results
   of operations of the Company and its subsidiaries, otherwise than as set
   forth or contemplated in the Prospectus as amended or supplemented, the
   effect of which, in any such case described in clause (i) or (ii), is in
   the judgment of the Representatives so material and adverse as to make it
   impracticable or inadvisable to proceed with the public offering or the
   delivery of the Designated Securities on the terms and in the manner
   contemplated in the Prospectus as amended or supplemented; 

        (f)  On or after the date of the Pricing Agreement relating to the
   Designated Securities (i) no downgrading shall have occurred in the rating
   accorded the Company's debt securities by any "nationally recognized
   statistical rating organization," as that term is defined by the Commission
   for purposes of Rule 436(g)(2) under the Act and (ii) no such organization
   shall have publicly announced that it has under surveillance or review,
   with possible negative implications, its rating of any of the Company's
   debt securities; 

        (g)  On or after the date of the Pricing Agreement relating to the
   Designated Securities there shall not have occurred any of the following:
   (i) a suspension or material limitation in trading in securities generally
   on the New York Stock Exchange; (ii) a suspension or material limitation in
   trading in the Company's securities on the New York Stock Exchange; (iii) a
   general moratorium on commercial banking activities in New York or Illinois
   (in the case of Illinois, only to the extent that a general moratorium on
   commercial banking activities in Illinois affects the Underwriters' ability
   to fulfill their obligations hereunder at the Time of Delivery) declared by
   either Federal or New York State or Illinois authorities; or (iv) an
   outbreak or escalation of hostilities involving the United States or the
   declaration by the United States of a national emergency or war, if the
   effect of any such event specified in this clause (iv) in the judgment of
   the Representatives makes it impracticable or inadvisable to proceed with
   the public offering or the delivery of the Designated Securities on the
   terms and in the manner contemplated in the Prospectus as amended or
   supplemented; and 


        (h)  The Company shall have furnished or caused to be furnished to the
   Representatives at the Time of Delivery for the Designated Securities a
   certificate or certificates of the Chairman or a Vice President and the
   Controller or Treasurer of the Company as to the accuracy of the
   representations and warranties of the Company herein at and as of such Time
   of Delivery, as to the performance by the Company of all of its obligations
   hereunder to be performed at or prior to such Time of Delivery, as to the
   matters set forth in subsections (a) and (e) of this Section and as to such
   other matters as the Representatives may reasonably request. 

        8. (a)  The Company will indemnify and hold harmless each Underwriter
   against any losses, claims, damages or liabilities, joint or several, to
   which such Underwriter may become subject, under the Act or otherwise,
   insofar as such losses, claims, damages or liabilities (or actions in
   respect thereof) arise out of or are based upon an untrue statement or
   alleged untrue statement of a material fact contained in any Preliminary
   Prospectus, any preliminary prospectus supplement, the Registration
   Statement, the Prospectus as amended or supplemented and any other
   prospectus relating to the Securities, or any amendment or supplement
   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, and will reimburse each
   Underwriter for any legal or other expenses reasonably incurred by such
   Underwriter in connection with investigating or defending any such action
   or claim as such expenses are incurred; provided, however, that the Company
   shall not be liable in any such case to the extent that any such loss,
   claim, damage or liability arises out of or is based upon an untrue
   statement or alleged untrue statement or omission or alleged omission made
   in any Preliminary Prospectus, any preliminary prospectus supplement, the
   Registration Statement, the Prospectus as amended or supplemented and any
   other prospectus relating to the Securities, or any such amendment or
   supplement in reliance upon and in conformity with written information
   furnished to the Company by any Underwriter of Designated Securities
   through the Representatives expressly for use in the Prospectus as amended
   or supplemented relating to such Securities. 

        (b)  Each Underwriter will indemnify and hold harmless the Company
   against any losses, claims, damages or liabilities to which the Company may
   become subject, under the Act or otherwise, insofar as such losses, claims,
   damages or liabilities (or actions in respect thereof) arise out of or are
   based upon an untrue statement or alleged untrue statement of a material
   fact contained in any Preliminary Prospectus, any preliminary prospectus
   supplement, the Registration Statement, the Prospectus as amended or
   supplemented and any other prospectus relating to the Securities, or any
   amendment or supplement 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 any Preliminary Prospectus, any preliminary prospectus
   supplement, the Registration Statement, the Prospectus as amended or
   supplemented and any other prospectus relating to the Securities, or any
   such amendment or supplement in reliance upon and in conformity with
   written information furnished to the Company by such Underwriter through
   the Representatives expressly for use therein; and will reimburse the
   Company for any legal or other expenses reasonably incurred by the Company
   in connection with investigating or defending any such action or claim as
   such expenses are incurred. 

        (c)  Promptly after receipt by an indemnified party under subsection
   (a) or (b) above of notice of the commencement of any action, such
   indemnified party shall, if a claim in respect thereof is to be made
   against the indemnifying party under such subsection, notify the


   indemnifying party in writing of the commencement thereof; but the omission
   so to notify the indemnifying party shall not relieve it from any liability
   which it may have to any indemnified party otherwise than under such
   subsection. In case any such action shall be brought against any
   indemnified party and it shall notify the indemnifying party of the
   commencement thereof, the indemnifying party shall be entitled to
   participate therein and, to the extent that it shall wish, jointly with any
   other indemnifying party similarly notified, to assume the defense thereof,
   with counsel satisfactory to such indemnified party (who shall not, except
   with the consent of the indemnified party, be counsel to the indemnifying
   party), and after notice from the indemnifying party to such indemnified
   party of its election so to assume the defense thereof, the indemnifying
   party shall not be liable to such indemnified party under such subsection
   for any legal expenses of other counsel or any other expenses, in each case
   subsequently incurred by such indemnified party, in connection with the
   defense thereof other than reasonable costs of investigation.  No
   indemnifying party shall, without the written consent of the indemnified
   party, effect the settlement or compromise of, or consent to the entry of
   any judgment with respect to, any pending or threatened action or claim in
   respect of which indemnification or contribution may be sought hereunder
   (whether or not the indemnified party is an actual or potential party to
   such action or claim) unless such settlement, compromise or judgment (i)
   includes an unconditional release of the indemnified party from all
   liability arising out of such action or claim and (ii) does not include a
   statement as to, or an admission of, fault, culpability or a failure to
   act, by or on behalf of any indemnified party.

        (d)  If the indemnification provided for in this Section 8 is
   unavailable to or insufficient to hold harmless an indemnified party under
   subsection (a) or (b) above in respect of any losses, claims, damages or
   liabilities (or actions in respect thereof) referred to therein, then each
   indemnifying party shall contribute to the amount paid or payable by such
   indemnified party as a result of such losses, claims, damages or
   liabilities (or actions in respect thereof) in such proportion as is
   appropriate to reflect the relative benefits received by the Company on the
   one hand and the Underwriters of the Designated Securities on the other
   from the offering of the Designated Securities to which such loss, claim,
   damage or liability (or action in respect thereof) relates. If, however,
   the allocation provided by the immediately preceding sentence is not
   permitted by applicable law or if the indemnified party failed to give the
   notice required under subsection (c) above, then each indemnifying party
   shall contribute to such amount paid or payable by such indemnified party
   in such proportion as is appropriate to reflect not only such relative
   benefits but also the relative fault of the Company on the one hand and the
   Underwriters of the Designated Securities on the other in connection with
   the statements or omissions which resulted in such losses, claims, damages
   or liabilities (or actions in respect thereof), as well as any other
   relevant equitable considerations. The relative benefits received by the
   Company on the one hand and such Underwriters on the other shall be deemed
   to be in the same proportion as the total net proceeds from such offering
   (before deducting expenses) received by the Company bear to the total
   underwriting discounts and commissions received by such Underwriters. The
   relative fault shall be determined by reference to, among other things,
   whether the untrue or alleged untrue statement of a material fact or the
   omission or alleged omission to state a material fact relates to
   information supplied by the Company on the one hand or such Underwriters on
   the other and the parties' relative intent, knowledge, access to
   information and opportunity to correct or prevent such statement or
   omission. The Company and the Underwriters agree that it would not be just
   and equitable if contribution pursuant to this subsection (d) were
   determined by per capita allocation (even if the Underwriters were treated
   as one entity for such purpose) or by any other method of allocation which
   does not take account of the equitable considerations referred to above in


   this subsection (d). The amount paid or payable by an indemnified party as
   a result of the losses, claims, damages or liabilities (or actions in
   respect thereof) referred to above in this subsection (d) shall be deemed
   to include any legal or other expenses reasonably incurred by such
   indemnified party in connection with investigating or defending any such
   action or claim. Notwithstanding the provisions of this subsection (d), no
   Underwriter shall be required to contribute any amount in excess of the
   amount by which the total price at which the applicable Designated
   Securities underwritten by it and distributed to the public were offered to
   the public exceeds the amount of any damages which such Underwriter has
   otherwise been required to pay by reason of such untrue or alleged untrue
   statement or omission or alleged omission. No person guilty of fraudulent
   misrepresentation (within the meaning of Section 11(f) of the Act) shall be
   entitled to contribution from any person who was not guilty of such
   fraudulent misrepresentation. The obligations of the Underwriters of
   Designated Securities in this subsection (d) to contribute are several in
   proportion to their respective underwriting obligations with respect to
   such Securities and not joint. 

        (e)  The obligations of the Company under this Section 8 shall be in
   addition to any liability which the Company may otherwise have and shall
   extend, upon the same terms and conditions, to each person, if any, who
   controls any Underwriter within the meaning of the Act; and the obligations
   of the Underwriters under this Section 8 shall be in addition to any
   liability which the respective Underwriters may otherwise have and shall
   extend, upon the same terms and conditions, to each officer and director of
   the Company and to each person, if any, who controls the Company within the
   meaning of the Act. 

        9. (a)  If any Underwriter shall default in its obligation to purchase
   the Designated Securities which it has agreed to purchase under the Pricing
   Agreement relating to such Designated Securities, the Representatives may
   in their discretion arrange for themselves or another party or other
   parties to purchase such Designated Securities on the terms contained
   herein and in the applicable Pricing Agreement. If within thirty-six hours
   after such default by any Underwriter the Representatives do not arrange
   for the purchase of such Designated Securities, then the Company shall be
   entitled to a further period of thirty-six hours within which to procure
   another party or other parties satisfactory to the Representatives to
   purchase such Designated Securities on such terms. In the event that,
   within the respective prescribed period, the Representatives notify the
   Company that they have so arranged for the purchase of such Designated
   Securities, or the Company notifies the Representatives that it has so
   arranged for the purchase of such Designated Securities, the
   Representatives or the Company shall have the right to postpone the Time of
   Delivery for such Designated Securities for a period of not more than
   seven days, in order to effect whatever changes may thereby be made
   necessary in the Registration Statement or the Prospectus as amended or
   supplemented, or in any other documents or arrangements, and the Company
   agrees to file promptly any amendments or supplements to the Registration
   Statement or the Prospectus which in the opinion of the Representatives may
   thereby be made necessary. The term "Underwriter" as used in this Agreement
   shall include any person substituted under this Section with like effect as
   if such person had originally been a party to the Pricing Agreement with
   respect to such Designated Securities. 

        (b)  If, after giving effect to any arrangements for the purchase of
   the Designated Securities of a defaulting Underwriter or Underwriters by
   the Representatives and the Company as provided in subsection (a) above,
   the aggregate principal amount of such Designated Securities which remains
   unpurchased does not exceed one-eleventh of the aggregate principal amount
   of the Designated Securities, then the Company shall have the right to
   require each non-defaulting Underwriter to purchase the principal amount of


   Designated Securities which such Underwriter agreed to purchase under the
   Pricing Agreement relating to such Designated Securities and, in addition,
   to require each non-defaulting Underwriter to purchase its pro rata share
   (based on the principal amount of Designated Securities which such
   Underwriter agreed to purchase under such Pricing Agreement) of the
   Designated Securities of such defaulting Underwriter or Underwriters for
   which such arrangements have not been made; but nothing herein shall
   relieve a defaulting Underwriter from liability for its default. 

        (c)  If, after giving effect to any arrangements for the purchase of
   the Designated Securities of a defaulting Underwriter or Underwriters by
   the Representatives and the Company as provided in subsection (a) above,
   the aggregate principal amount of Designated Securities which remains
   unpurchased exceeds one-eleventh of the aggregate principal amount of the
   Designated Securities, as referred to in subsection (b) above, or if the
   Company shall not exercise the right described in subsection (b) above to
   require non-defaulting Underwriters to purchase Designated Securities of a
   defaulting Underwriter or Underwriters, then the Pricing Agreement relating
   to such Designated Securities shall thereupon terminate, without liability
   on the part of any non-defaulting Underwriter or the Company, except for
   the expenses to be borne by the Company and the Underwriters as provided in
   Section 6 hereof and the indemnity and contribution agreements in Section 8
   hereof; but nothing herein shall relieve a defaulting Underwriter from
   liability for its default. 

        10.  The respective indemnities, agreements, representations,
   warranties and other statements of the Company and the several
   Underwriters, as set forth in this Agreement or made by or on behalf of
   them, respectively, pursuant to this Agreement, shall remain in full force
   and effect, regardless of any investigation (or any statement as to the
   results thereof) made by or on behalf of any Underwriter or any controlling
   person of any Underwriter, or the Company, or any officer or director or
   controlling person of the Company, and shall survive delivery of and
   payment for the Securities. 

        11.  If any Pricing Agreement shall be terminated pursuant to
   Section 9 hereof, the Company shall not then be under any liability to any
   Underwriter with respect to the Designated Securities covered by such
   Pricing Agreement except as provided in Section 6 and Section 8 hereof;
   but, if for any other reason Designated Securities are not delivered by or
   on behalf of the Company as provided herein, the Company will reimburse the
   Underwriters through the Representatives for all out-of-pocket expenses
   approved in writing by the Representatives, including fees and
   disbursements of counsel, reasonably incurred by the Underwriters in making
   preparations for the purchase, sale and delivery of such Designated
   Securities, but the Company shall then be under no further liability to any
   Underwriter with respect to such Designated Securities except as provided
   in Section 6 and Section 8 hereof. 

        12.  In all dealings hereunder, the Representatives of the
   Underwriters of Designated Securities shall act on behalf of each of such
   Underwriters, and the parties hereto shall be entitled to act and rely upon
   any statement, request, notice or agreement on behalf of any Underwriter
   made or given by such Representatives jointly or by such of the
   Representatives, if any, as may be designated for such purpose in the
   Pricing Agreement. 

        All statements, requests, notices and agreements hereunder shall be in
   writing, and if to the Underwriters shall be delivered or sent by mail,
   telex or facsimile transmission to the address of the Representatives as
   set forth in the Pricing Agreement; and if to the Company shall be
   delivered or sent by mail, telex or facsimile transmission to the address
   of the Company set forth in the Registration Statement: Attention:


   Secretary; provided, however, that any notice to an Underwriter pursuant to
   Section 8(c) hereof shall be delivered or sent by mail or facsimile
   transmission to such Underwriter at its address set forth in its
   Underwriters' Questionnaire, or telex constituting such Questionnaire,
   which address will be supplied to the Company by the Representatives upon
   request. Any such statements, requests, notices or agreements shall take
   effect upon receipt thereof. 

        13.  This Agreement and each Pricing Agreement shall be binding upon,
   and inure solely to the benefit of, the Underwriters, the Company and, to
   the extent provided in Section 8 and Section 10 hereof, the officers and
   directors of the Company and each person who controls the Company or any
   Underwriter, and their respective heirs, executors, administrators,
   successors and assigns, and no other person shall acquire or have any right
   under or by virtue of this Agreement or any such Pricing Agreement. No
   purchaser of any of the Securities from any Underwriter shall be deemed a
   successor or assign by reason merely of such purchase. 

        14.  Time shall be of the essence of each Pricing Agreement. As used
   herein, "business day" shall mean any day when the Commission's office in
   Washington, D.C. is open for business. 

        15.  This Agreement and each Pricing Agreement shall be construed in
   accordance with the laws of the State of New York. 

        16.  This Agreement and each Pricing Agreement may be executed by any
   one or more of the parties hereto and thereto in any number of
   counterparts, each of which shall be deemed to be an original, but all such
   respective counterparts shall together constitute one and the same
   instrument. 

        If the foregoing is in accordance with your understanding, please sign
   and return to us 10 counterparts hereof.

                                      Very truly yours,

                                      Mallinckrodt Group Inc.

   Goldman, Sachs & Co.

      As Representatives of the several
      Underwriters named in Schedule I hereto,
   c/o Goldman, Sachs & Co.
   85 Broad Street
   New York, New York 10004

                                           , 199  

   Dear Sirs: 

        Mallinckrodt Group Inc., a New York corporation (the "Company"),
   proposes, subject to the terms and conditions stated herein and in the
   Underwriting Agreement, dated              , 199    (the "Underwriting
   Agreement"), between the Company on the one hand and Goldman, Sachs & Co.
   and J.P. Morgan Securities Inc. on the other hand, to issue and sell to the
   Underwriters named in Schedule I hereto (the "Underwriters") the Securities
   specified in Schedule II hereto (the "Designated Securities"). Each of the
   provisions of the Underwriting Agreement is incorporated herein by
   reference in its entirety, and shall be deemed to be a part of this
   Agreement to the same extent as if such provisions had been set forth in
   full herein; and each of the representations and warranties set forth
   therein shall be deemed to have been made at and as of the date of this
   Pricing Agreement, except that each representation and warranty which
   refers to the Prospectus in Section 2 of the Underwriting Agreement shall
   be deemed to be a representation or warranty as of the date of the
   Underwriting Agreement in relation to the Prospectus (as therein defined),
   and also a representation and warranty as of the date of this Pricing
   Agreement in relation to the Prospectus as amended or supplemented relating
   to the Designated Securities which are the subject of this Pricing
   Agreement. Each reference to the Representatives herein and in the
   provisions of the Underwriting Agreement so incorporated by reference shall
   be deemed to refer to you. Unless otherwise defined herein, terms defined
   in the Underwriting Agreement are used herein as therein defined. The
   Representatives designated to act on behalf of the Representatives and on

                                     ANNEX II
        Pursuant to Section 7(d) of the Underwriting Agreement, the Company's
   independent certified public accountants shall furnish letters to the
   Underwriters to the effect that: 
        (i)  They are independent auditors with respect to the Company and its
   subsidiaries within the meaning of the Act and the applicable published
   rules and regulations thereunder; 
        (ii) In their opinion, the consolidated financial statements and any
   supplementary financial information and schedules (and, if applicable,
   prospective financial statements and/or pro forma financial information)
   examined by them and included or incorporated by reference in the
   Registration Statement or the Prospectus comply as to form in all material
   respects with the applicable accounting requirements of the Act or the
   Exchange Act, as applicable, and the related published rules and
   regulations thereunder; and, if applicable, they have made a review in
   accordance with standards established by the American Institute of
   Certified Public Accountants of the consolidated interim financial
   statements, selected financial data, pro forma financial information,
   prospective financial statements and/or condensed financial statements
   derived from audited financial statements of the Company for the periods
   specified in such letter, as indicated in their reports thereon, copies of
   which have been furnished to the representatives of the Underwriters (the
   "Representatives"); 
        (iii)     They have made a review in accordance with standards
   established by the American Institute of Certified Public Accountants of
   the unaudited condensed consolidated statements of income, consolidated
   balance sheets and consolidated statements of cash flows included in the
   Prospectus and/or included in the Company's quarterly report on Form 10-Q
   incorporated by reference into the Prospectus as indicated in their reports
   thereon copies of which have been furnished to the Agents; and on the basis
   of specified procedures including inquiries of officials of the Company who
   have responsibility for financial and accounting matters regarding whether
   the unaudited condensed consolidated financial statements referred to in
   paragraph (vi)(A)(i) below comply as to form in all material respects with
   the applicable accounting requirements of the Act and the Exchange Act and
   the related published rules and regulations thereunder, nothing came to
   their attention that caused them to believe that the unaudited condensed
   consolidated financial statements do not comply as to form in all material
   respects with the applicable accounting requirements of the Act and the
   Exchange Act and the related published rules and regulations; 
        (iv) The unaudited selected financial information with respect to the
   consolidated results of operations and financial position of the Company
   for the five most recent fiscal years included in the Prospectus and
   included or incorporated by reference in Item 6 of the Company's Annual
   Report on Form 10-K for the most recent fiscal year agrees with or is
   derived from (specifying in each case which) the corresponding amounts
   (after restatement where applicable) in the audited consolidated financial
   statements for five such fiscal years which were included or incorporated
   by reference in the Company's Annual Reports on Form 10-K for such
   fiscal years; 
        (v)  They have compared the information in the Prospectus under
   selected captions with the disclosure requirements of Regulation S-K and on
   the basis of limited procedures specified in such letter nothing came to
   their attention as a result of the foregoing procedures that caused them to
   believe that this information does not conform in all material respects
   with the disclosure requirements of Items 301, 302, 402 and 503(d),
   respectively, of Regulation S-K; 
        (vi) On the basis of limited procedures, not constituting an audit in
   accordance with generally accepted auditing standards, consisting of a
   reading of the unaudited financial statements and other information
   referred to below, a reading of the latest available interim financial
   statements of the Company, inspection of the minute books of the Company
   since the date of the latest audited financial statements included or
   incorporated by reference in the Prospectus, inquiries of officials of the
   Company responsible for financial and accounting matters and such other
   inquiries and procedures as may be specified in such letter, nothing came
   to their attention that caused them to believe that: 
        (A)  the unaudited condensed consolidated statements of income,
   consolidated balance sheets and consolidated statements of cash flows
   included in the Prospectus and/or included or incorporated by reference in
   the Company's Quarterly Reports on Form 10-Q incorporated by reference in
   the Prospectus (i) do not comply as to form in all material respects with
   the applicable accounting requirements of the Exchange Act and the related


   published rules and regulations thereunder, or (ii) are not in conformity
   with generally accepted accounting principles applied on a basis
   substantially consistent with the basis for the audited consolidated
   statements of income, consolidated balance sheets and consolidated
   statements of cash flows included or incorporated by reference in the more
   recent of the Company's Annual Report on Form 10-K for the most recent
   fiscal year or the Prospectus;  
        (B)  any other unaudited income statement data and balance sheet items
   included in the Prospectus do not agree with the corresponding items in the
   unaudited consolidated financial statements from which such data and items
   were derived, and any such unaudited data and items were not determined on
   a basis substantially consistent with the basis for the corresponding
   amounts in the audited consolidated financial statements included or
   incorporated by reference in the more recent of the Company's Annual Report
   on Form 10-K for the most recent fiscal year or the Prospectus; 
        (C)  the unaudited financial statements which were not included in the
   Prospectus but from which were derived the unaudited condensed financial
   statements referred to in Clause (A) and any unaudited income statement
   data and balance sheet items included in the Prospectus and referred to in
   Clause (B) were not determined on a basis substantially consistent with the
   basis for the audited financial statements included or incorporated by
   reference in the more recent of the Company's Annual Report on Form 10-K
   for the most recent fiscal year or the Prospectus; 
        (D)  any unaudited pro forma consolidated condensed financial
   statements included or incorporated by reference in the Prospectus do not
   comply as to form in all material respects with the applicable accounting
   requirements of the Act and the published rules and regulations thereunder
   and, if applicable, the pro forma adjustments have not been properly
   applied to the historical amounts in the compilation of those statements; 
        (E)  as of a specified date not more than five days prior to the date
   of such letter, there have been any changes in the consolidated capital
   stock (other than issuances of capital stock upon exercise of options and
   stock appreciation rights, upon earn-outs of performance shares and upon
   conversions of convertible securities, in each case which were outstanding
   on the date of the latest balance sheet included or incorporated by
   reference in the Prospectus) or any increase in the consolidated long-term
   debt of the Company and its subsidiaries, or any decreases in consolidated
   net current assets or stockholders' equity or other items specified by the
   Representatives, as agreed to by the auditors, or any increases in any
   items specified by the Representatives, as agreed to by the auditors, in
   each case as compared with amounts shown in the latest balance sheet
   included or incorporated by reference in the Prospectus, except in each
   case for changes, increases or decreases which the Prospectus discloses
   have occurred or may occur or which are described in such letter; and 
        (F)  for the period from the date of the latest financial statements
   included or incorporated by reference in the Prospectus to the specified
   date referred to in Clause (E) there were any decreases in consolidated net
   revenues or operating profit or the total or per share amounts of
   consolidated net income or other items specified by the Representatives, as
   agreed to by the auditors, or any increases in any items specified by the
   Representatives, as agreed to by the auditors, in each case as compared
   with the comparable period of the preceding year and with any other period
   of corresponding length specified by the Representatives, as agreed to by
   the auditors, except in each case for increases or decreases which the
   Prospectus discloses have occurred or may occur or which are described in
   such letter; and 
        (vii)     In addition to the audit referred to in their report(s)
   included or incorporated by reference in the Prospectus and the limited
   procedures, inspection of minute books, inquiries and other procedures
   referred to in paragraphs (iii) and (vi) above, they have carried out
   certain specified procedures, not constituting an audit in accordance with
   generally accepted auditing standards, with respect to certain amounts,
   percentages and financial information specified by the Representatives, as
   agreed to by the auditors, which are derived from the general accounting
   records of the Company and its subsidiaries, which appear in the Prospectus
   (excluding documents incorporated by reference), or in Part II of, or in
   exhibits and schedules to, the Registration Statement specified by the
   Representatives, as agreed to by the auditors, or in documents incorporated
   by reference in the Prospectus specified by the Representatives, as agreed
   to by the auditors, and have compared certain of such amounts, percentages
   and financial information with the accounting records of the Company and
   its subsidiaries and have found them to be in agreement. 
        All references in this Annex II to the Prospectus shall be deemed to
   refer to the Prospectus (including the documents incorporated by reference
   therein) as defined in the Underwriting Agreement as of the date of the
   letter delivered on the date of the Pricing Agreement for purposes of such
   letter and to the Prospectus as amended or supplemented (including the
