                           [_______________, 199_]

Goldman, Sachs & Co.
As Representatives of the
  several Underwriter's 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 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) A registration statement on Form S-3 (File No. 333-_________) in
respect of the Securities has been filed with the Securities and Exchange
Commission (the "Commission"); such registration statement as it may have been
amended prior to its 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), has
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 the registration statement 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 statement, including all
exhibits thereto and the documents incorporated by reference in the prospectus
contained in such registration statement 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

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

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,

      (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

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

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 

                                       9

 
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) Prior to 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 (the executed copy of the letter delivered
prior to the execution of this Agreement is attached as Annex I(a) hereto and a
draft of the form of letter to be delivered on the effective date of any
post-effective amendment to the Registration Statement and as of each Time of
Delivery is attached as Annex I(b) hereto);

      (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;


                                      10

 
      (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;

      (h) The Company shall have complied with the provisions of Section 5(c)
hereof with respect to the furnishing of Prospectuses on the New York Business
Day next succeeding the date of this Agreement; and

      (i) 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 

                                      11

 
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 

                                      12

 
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 

                                      13

 
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 

                                      14

 
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,

Dear Sirs:

      Mallinckrodt 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. 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 behalf of each of the Underwriters
of the Designated Securities pursuant to Section 12 of the Underwriting
Agreement and the address of the Representatives referred to in such Section 12
are set forth at the end of Schedule II hereto.

      An amendment to the Registration Statement, or a supplement to the
Prospectus, as the case may be, relating to the Designated Securities, in the
form heretofore delivered to you is now proposed to be filed with the
Commission.

      Subject to the terms and conditions set forth herein and in the
Underwriting Agreement incorporated herein by reference, the Company agrees to
issue and sell to each of the Underwriters, and each of the Underwriters agrees,
severally and not jointly, to purchase from the Company, at the time and place
and at the purchase price to the Underwriters set forth in Schedule II hereto,
the principal amount of Designated Securities set forth opposite the name of
such Underwriter in Schedule I hereto.

 
      If the foregoing is in accordance with your understanding, please sign and
return to us 10 counterparts hereof, and upon acceptance hereof by you, on
behalf of each of the Underwriters, this letter and such acceptance hereof,
including the provisions of the Underwriting Agreement incorporated herein by
reference, shall constitute a binding agreement between each of the Underwriters
and the Company. It is understood that your acceptance of this letter on behalf
of each of the Underwriters is or will be pursuant to the authority set forth in
a form of Agreement among Underwriters, the form of which shall be submitted to
the Company for examination upon request, but without warranty on the part of
the Representatives as to the authority of the signers thereof.

                                          Very truly yours,

                                          Mallinckrodt Inc.

                                   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 Representatives; 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) 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


                                      2

 
      (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
