                             PRODUCT DEVELOPMENT AND

                           COMMERCIALIZATION AGREEMENT

      THIS PRODUCT DEVELOPMENT AND COMMERCIALIZATION AGREEMENT (the "Agreement")
is made and entered into by and between ARADIGM CORPORATION, a California
corporation having its principal place of business at 26219 Eden Landing Road,
Hayward, California 94545 ("Aradigm"), and SMITHKLINE BEECHAM, PLC, a United
Kingdom corporation having a principal place of business at New Horizons Court,
Brentford, Middlesex, TW8 9EP England ("SB"), as of September 30, 1997 (the
"Effective Date"). Aradigm and SB may be referred to herein as a "Party" or,
collectively, as "Parties."

                                   BACKGROUND

      A. Aradigm has developed and owns the rights to a drug delivery system
known as the AERx(TM) Pain Management System. This system may be capablE of
delivering certain properly formulated analgesic drugs via inhalation to treat
pain. To date, Aradigm has committed its own resources to complete Phase I
testing of an AERx-morphine sulfate product and 28-day pre-clinical pulmonary
toxicology studies with respect to such product and has discussed the regulatory
requirements of such AERx system with the FDA.

      B. Aradigm desires to enter into a collaborative relationship to support
the completion of human clinical development of such AERx system for its use in
the delivery of certain analgesic drugs for use in both inpatient and outpatient
pain management settings and to commercialize the AERx system, once appropriate
regulatory approval has been achieved, in conjunction with such analgesic drugs.

      C. SB has substantial experience in the distribution, marketing and sale
of pharmaceuticals. SB is willing to support Aradigm's efforts to complete
development of the AERx system for its use in delivering certain analgesic drugs
and obtain worldwide regulatory approval to market Aradigm's AERx system in
conjunction with such analgesic drugs for pain management, in order to obtain
exclusive marketing rights to such AERx system.

      D. The Parties desire to enter into an agreement establishing the
development and supply terms under which, at the direction of a development
committee and a commercialization committee to be formed by the Parties, (a)
Aradigm will be responsible (i) for completing development of the AERx device
and drug packet for use in the delivery of certain analgesic drugs for pain
management, (ii) for collaborating with SB on conducting the required clinical
trials and obtaining the necessary marketing approvals, with SB's cooperation
and certain financial support, and (iii) for manufacturing and supplying to SB
the approved AERx system and formulated analgesic drugs in finished form, and
(b) SB will collaborate with Aradigm in conducting such clinical trials and will
have exclusive, worldwide rights to market and sell such AERx system and drugs
for use in pain management. Contemporaneously with this Agreement, the Parties
are also entering into a Stock Purchase Agreement pursuant to which SB shall
purchase from Aradigm up to $10 million in Aradigm equity.

2.3, the DEVELOPMENT COMMITTEE shall prepare a proposed budget (the "Proposed
Budget") to account for the DEVELOPMENT COSTS to be expended or incurred by each
Party in conducting the DEVELOPMENT tasks undertaken under such DEVELOPMENT PLAN
for the applicable AERx SYSTEM or PRODUCT. Such Proposed Budget shall be
prepared no more than thirty (30) days after completion of the applicable
DEVELOPMENT PLAN, and shall include, without limitation, the DEVELOPMENT COSTS
to be expended or incurred by each Party.

            (b) Upon completion of each such Proposed Budget by the DEVELOPMENT
COMMITTEE, such Proposed Budget shall be submitted to each Party. Each Party
shall have the right to review and approve each such Proposed Budget. Any
changes to the Proposed Budget suggested by a Party shall be submitted in
writing to the other Party and the DEVELOPMENT COMMITTEE no more than thirty
(30) days after receipt of the Proposed Budget by the Party, and the DEVELOPMENT
COMMITTEE shall consider all such changes in good faith and shall prepare a
revised Proposed Budget reflecting the changes submitted by each Party. Such
revised Proposed Budget shall then be provided to each Party for the same review
and approval process provided above. Such review process shall continue until
each Party has approved such Proposed Budget, at which point such approved
Proposed Budget shall be deemed to be the binding budget for incurring or
expenditure of DEVELOPMENT COSTS by each of the Parties with respect to
DEVELOPMENT of the applicable AERx SYSTEM or PRODUCT (a "BUDGET"), subject to
amendment as provided in subsection (c) below.

            (c) Aradigm shall use DILIGENT EFFORTS to comply with the applicable
BUDGET with respect to Aradigm's incurring of DEVELOPMENT COSTS for each
particular DEVELOPMENT activity and the other costs provided for in the BUDGET
for the relevant activity during the applicable calendar year. In the event that
Aradigm does incur any expenses for a particular activity that exceed the BUDGET
therefor, such event shall not be considered a breach of this Agreement by
Aradigm, but SB shall not be responsible for funding any such excess amount,
unless otherwise agreed by the Parties. If Aradigm believes that completion of
the assigned DEVELOPMENT tasks or other tasks for which costs are provided in
the BUDGET during such year will exceed the portion of the BUDGET that is to be
funded by SB and that is allocated for Aradigm's efforts, Aradigm will contact
the DEVELOPMENT COMMITTEE promptly after such determination in order to initiate
discussion by the DEVELOPMENT COMMITTEE of such matter and appropriate means of
resolving same. In addition, changes to the SPECIFICATIONS or other changes in
DEVELOPMENT PLANS may necessitate changes in the applicable BUDGET, due to
required changes in the Parties' respective DEVELOPMENT efforts. The DEVELOPMENT
COMMITTEE shall consider in good faith any needed adjustments to the BUDGET
resulting from any of the foregoing. The DEVELOPMENT COMMITTEE may agree, after
the approval of the BUDGET for DEVELOPMENT COSTS for 



                                       12

increase in DEVELOPMENT funding BUDGET for such DEVELOPMENT, and such
recommendation shall be duly considered by SB. Any changes to the BUDGET
recommended by the DEVELOPMENT COMMITTEE and approved by SB shall be made in
writing and signed by each PARTY.

            (d) Except as otherwise agreed by the Parties, SB shall provide
funding to Aradigm for the DEVELOPMENT COSTS incurred by Aradigm in accordance
with the agreed BUDGETS, but excluding any costs incurred with respect to the
efforts to be conducted by Aradigm at its expense as provided in subsection (e)
below. Such funding shall be paid in advance to Aradigm for each calendar
quarter, according to the DEVELOPMENT COSTS outlined in the relevant BUDGET to
be incurred by Aradigm during the coming calendar quarter during each year in
which Aradigm is conducting DEVELOPMENT, with the first installment to be paid
no later than thirty (30) days after the Effective Date, and each installment
thereafter to be paid by the first day of the respective calendar quarter. For
each calendar quarter after the Effective Date during which Aradigm conducts
DEVELOPMENT, Aradigm shall submit a report to SB no more than forty-five (45)
days after the beginning of such calendar quarter, which report shall set forth
Aradigm's determination of the actual DEVELOPMENT COSTS incurred by Aradigm in
conducting DEVELOPMENT work during the previous calendar quarter. If such report
indicates that Aradigm expended less than the amount funded by SB, as provided
herein, for such quarter in completing tasks assigned for such quarter under the
DEVELOPMENT PLAN (but excluding tasks Aradigm is to perform at its expense under
subsection (e)), such amounts that were not expended may be credited by SB
against the amounts to be paid by SB hereunder at the beginning of the next
quarter. If such report indicates that Aradigm expended less than the amount
funded by SB for such quarter because Aradigm was unable to conduct or to
complete certain tasks assigned for such quarter under the DEVELOPMENT PLAN, SB
shall bring such matter to the DEVELOPMENT COMMITTEE, which shall determine
whether to reallocate the unexpended funding provided to Aradigm with respect to
such tasks, in order to accomplish the tasks that were not conducted or
completed.

            (e) Aradigm shall be responsible for providing all funding required
to support the conduct of all Aradigm's responsibilities as set forth in the
agreed summary DEVELOPMENT PLAN (attached hereto as Exhibit B) for work
performed by Aradigm for DEVELOPMENT of the INITIAL PRODUCT under this
Agreement, but excluding all efforts (the "Funded Work") of Aradigm relating to
(i) [*] (including all Aradigm's manpower and out-of-pocket expenses relating to
such work and the [*] (ii) [*] and (iii) [*]. All DEVELOPMENT COSTS
associated with conducting such Funded Work shall be funded by SB under
subsection (d) above, consistent with the applicable BUDGET. In the event that
the detailed DEVELOPMENT PLAN agreed to by the Parties as provided in Section
2.3 for the DEVELOPMENT of the INITIAL PRODUCT (as such plan may be amended or
modified by the Parties) requires that Aradigm expend or incur in excess of [*]

[*] in conducting such DEVELOPMENT pursuant to such DEVELOPMENT PLAN
(but excluding the Funded Work), then SB shall provide funding to Aradigm to
support such additional Aradigm efforts or work, provided that the extent of
such funding by SB shall be limited to the amount approved by SB management in
the relevant BUDGET, as originally approved or subsequently modified.

      2.5 REPORTS. Each Party shall maintain accurate and complete records of
all DEVELOPMENT activities and all results of any trials, studies and other
investigations conducted by or on behalf of such Party hereunder. At least ten
(10) days prior to each meeting of the DEVELOPMENT COMMITTEE, each Party shall
prepare a written report for the DEVELOPMENT COMMITTEE summarizing the progress
of the work, successes, problems, and delays in that period. Based on
information in such reports and other information known to the DEVELOPMENT
COMMITTEE, the DEVELOPMENT COMMITTEE shall review the relevant DEVELOPMENT PLANS
for the remainder of the year to see if modification is required. The general
format of the reports shall be as agreed by the Parties from time to time, and
shall be delivered to the DEVELOPMENT COMMITTEE and the other Party. Such
reports shall include, without limitation, discussions related to any
significant deviations from the DEVELOPMENT PLAN and proposed actions to address
such significant deviations, but need not restate items specifically reported to
the regular meetings of the DEVELOPMENT COMMITTEE.

      2.6   DEVELOPMENT DILIGENCE.

            (a) SB and Aradigm agree that the Parties shall seek to obtain
REGULATORY APPROVAL of the INITIAL PRODUCT and any other AERx SYSTEM chosen for
DEVELOPMENT by the DEVELOPMENT COMMITTEE in all of the MAJOR MARKET COUNTRIES,
and that each Party shall use DILIGENT EFFORTS to conduct such DEVELOPMENT
efforts as are outlined in the relevant DEVELOPMENT PLAN to obtain such
REGULATORY APPROVALS as soon as practicable and subject to the regulatory and
other legal requirements in the relevant country. The Parties also shall use
DILIGENT EFFORTS to conduct such DEVELOPMENT efforts as are required to obtain
REGULATORY APPROVAL of the INITIAL PRODUCT and any other AERx SYSTEM chosen for
DEVELOPMENT by the DEVELOPMENT COMMITTEE in each additional country of the
TERRITORY selected by the COMMERCIALIZATION COMMITTEE, pursuant to Section 5.3,
for commercialization of such particular AERx SYSTEM.

            (b) The Parties agree to use DILIGENT EFFORTS in accordance with the
applicable DEVELOPMENT PLAN in conducting the DEVELOPMENT of the INITIAL PRODUCT
with the goal of obtaining, if possible, REGULATORY APPROVAL in all MAJOR MARKET
COUNTRIES with respect to [*] the INITIAL PRODUCT in managing pain, which [*] in
the particular countries for use of the INITIAL PRODUCT for both post-operative
pain and alleviation of acute exacerbations of [*]. The Parties agree further
that if DEVELOPMENT of the INITIAL PRODUCT with the intention of [*] for
management of pain is not permitted in a particular country, the Parties will
proceed using DILIGENT EFFORTS with the

DEVELOPMENT of the INITIAL PRODUCT in such countries to [*] of the
INITIAL PRODUCT for both post-operative pain and alleviation of acute
exacerbations of [*] to the extent that such is permitted.
SB agrees to use DILIGENT EFFORTS to meet the schedule established in the
applicable DEVELOPMENT PLAN for achieving specific clinical DEVELOPMENT
milestones in the DEVELOPMENT of the INITIAL PRODUCT in the MAJOR MARKET
COUNTRIES. SB shall be deemed to have used DILIGENT EFFORTS if SB has achieved
specified DEVELOPMENT milestones with respect to the INITIAL PRODUCT no later
than the dates set forth in subsections (c) and (d) below, subject to any
adjustment of such dates as provided in subsection (e) below, with the
understanding that achievement of a specified DEVELOPMENT milestone with respect
to DEVELOPMENT for the general indication of management of pain shall be deemed
to satisfy the relevant milestones for each of subsections (c) and (d) below.

            (c) [*] PAIN INDICATION. With respect to each of the
following MAJOR MARKET COUNTRIES - U.S.A., France, Germany, United Kingdom,
Japan and China - SB shall use DILIGENT EFFORTS to attempt to achieve the
following DEVELOPMENT milestones by the applicable date with respect to
DEVELOPMENT of the INITIAL PRODUCT for use in managing [*]

      o     INITIATION of PHASE III TRIAL for the INITIAL PRODUCT needed to
            support the relevant APPROVAL APPLICATION for [*] within [*] of the
            date specified for commencement of such trial in the applicable
            DEVELOPMENT PLAN as such plan existed upon commencement of the first
            PHASE II TRIAL on the INITIAL PRODUCT in a MAJOR MARKET COUNTRY.

      o     Filing of relevant APPROVAL APPLICATION for [*] within [*] of the
            date specified for filing such application in the applicable
            DEVELOPMENT PLAN as such plan existed upon commencement of the first
            PHASE III TRIAL on the INITIAL PRODUCT in a MAJOR MARKET COUNTRY.

            (d) [*] INDICATION. With respect to each of the following countries
- - U.S.A., France, Germany, United Kingdom, Japan and China - SB shall achieve
the following DEVELOPMENT milestones by the applicable date with respect to
DEVELOPMENT of the INITIAL PRODUCT for use in the alleviation of acute
exacerbations of [*] cancer patients, etc.):

      o     INITIATION of PHASE III TRIAL needed to support relevant APPROVAL
            APPLICATION for acute exacerbations of [*] within [*] of the date
            specified for commencement of such trial in the applicable
            DEVELOPMENT PLAN as such plan existed upon commencement of the first
            PHASE II TRIAL on the INITIAL PRODUCT in a MAJOR MARKET COUNTRY.

      o     Filing of relevant APPROVAL APPLICATION for acute exacerbations of
            [*] within [*] of the date specified for filing such application in
            the applicable DEVELOPMENT PLAN as such plan existed upon
            commencement of the first PHASE III TRIAL on the INITIAL PRODUCT in
            a MAJOR MARKET COUNTRY.

            (e) ADJUSTMENTS OF DATES FOR ACHIEVING MILESTONES. The dates set
forth in subsection (c) or (d) above for achieving the specified DEVELOPMENT
milestones may be adjusted for a particular milestone only as provided herein,
or as otherwise agreed in writing. If any of the following events occur: (i) a
change in the SPECIFICATIONS of the applicable PRODUCT that requires additional
DEVELOPMENT effort beyond that set forth in the then-existing DEVELOPMENT PLAN;
(ii) a change relating to the medical, scientific, or regulatory criteria or
attributes of the applicable PRODUCT, which change is beyond SB's reasonable
control; (iii) delays in Aradigm's conduct of its responsibilities under the
applicable DEVELOPMENT PLAN; or (iv) Aradigm's delay in or failure to supply to
SB the quantities of the applicable PRODUCT or placebo for clinical trial use
within the amounts and time frame established by the applicable DEVELOPMENT
PLAN; and if the occurrence of one of the foregoing events causes a material
delay in SB's ability to conduct DEVELOPMENT on such PRODUCT with respect to
achievement of a particular DEVELOPMENT milestone required to be achieved under
subsection (c) or (d) above, then the required date for achieving such
DEVELOPMENT milestone shall be delayed by the amount of time that SB can
reasonably establish it was delayed, due to the occurrence of such event, in
conducting such DEVELOPMENT efforts.

            (f) REMEDY FOR FAILURE TO MEET MILESTONE. In the event that SB fails
to meet a specified DEVELOPMENT milestone for the INITIAL PRODUCT in a
particular MAJOR MARKET COUNTRY by the applicable date, as required in
subsection (c) and (d) above, as such date may be adjusted under subsection (e)
above, Aradigm shall have the option, upon its written notice to SB delivered no
later than [*] after such failure, of [*] under this Agreement in such MAJOR
MARKET COUNTRY, and such [*] with respect to SB PROPRIETARY DRUGS, if any.
Notwithstanding the foregoing, however, it is agreed that if the [*] for the
indications of the management of pain, post-operative pain, and/or alleviation
of acute exacerbations of [*] is not legally permitted in a particular MAJOR
MARKET COUNTRY by the applicable governmental authorities, there shall be no
requirement for SB to achieve any DEVELOPMENT milestone in such country for such
indication that is not permitted, and this subsection (f) shall no longer be
applicable with respect to such DEVELOPMENT milestone for such indication in
such country.

      2.7 SPECIFICATIONS; MODIFICATIONS TO AERX DEVICE. The DEVELOPMENT
COMMITTEE shall set the SPECIFICATIONS with respect to each AERx SYSTEM selected
for DEVELOPMENT and may modify such SPECIFICATIONS as appropriate, but subject
to the applicable BUDGET. The summary SPECIFICATIONS for the INITIAL PRODUCT are
attached hereto as Exhibit C, reflecting the Parties' agreement and
understanding as of the

<PAGE>   22

Effective Date of the performance and features of the INITIAL PRODUCT. Promptly
after the Effective Date, the DEVELOPMENT COMMITTEE shall prepare the agreed
detailed SPECIFICATIONS for the INITIAL PRODUCT. During the term of the
Agreement, Aradigm shall have the right to make modifications or changes to any
PRODUCT and will provide SB's V.P. and Director, WSO/QA with prior notice of
such modifications or changes; provided, however, that any such modifications or
changes that, in Aradigm's or SB's reasonable opinion, would: (i) result in a
change to the SPECIFICATIONS; (ii) adversely affect the related IND or APPROVAL
APPLICATION for the related PRODUCT; (iii) materially delay Aradigm's completion
of related tasks under the DEVELOPMENT PLAN for such PRODUCT; (iv) increase the
MANUFACTURING COSTS for the affected PRODUCT or (v) adversely affect market
receptivity to the PRODUCT; shall be subject to the prior approval of the
DEVELOPMENT COMMITTEE. SB's V.P. and Director, WSO/QA shall review any such
Aradigm notice of a proposed modification or change to determine if SB believes
such modification or change meets any of the criteria set forth in subsections
(i) through (v) above. If, based on such review, SB reasonably believes that
such proposed modification or change meets one (or more) of the criteria, SB
shall provide Aradigm, within twenty (20) days of receipt of Aradigm's notice,
written notice indicating such belief and the basis for such belief, and such
proposed change or modification shall then be referred to the DEVELOPMENT
COMMITTEE for review. At Aradigm's reasonable request for proposed modifications
or changes that may meet the criteria set forth above, the DEVELOPMENT COMMITTEE
will attempt to meet promptly in order to discuss the proposed modifications or
changes to determine whether to approve such proposals. For any such approved
changes in the SPECIFICATIONS, the DEVELOPMENT COMMITTEE shall agree on the
appropriate changes required to the applicable DEVELOPMENT PLAN, and the
following shall be applicable:

            (a) If the approved changes or modifications are, in the judgment of
the DEVELOPMENT COMMITTEE, expected to be useful only in the FIELD, then SB
shall be obligated to pay the DEVELOPMENT COSTS to implement such changes.

            (b) If the approved changes or modifications are, in the judgment of
the DEVELOPMENT COMMITTEE, expected to be used in products of Aradigm other than
the AERx SYSTEM in addition to use in the AERx SYSTEM, then the costs of making
such changes or modifications shall be borne by Aradigm.

      2.8 DATA MANAGEMENT SERVICE. The Parties acknowledge that Aradigm intends
to explore the development and marketing of data management and related services
based on the data collection capabilities of the AERx DEVICE and reserves the
right to do so, provided that SB shall also have the right to do so. Aradigm and
SB each will report to the DEVELOPMENT COMMITTEE and COMMERCIALIZATION COMMITTEE
from time to time on its plans and efforts in this area. The manner in which any
such service based on the AERx SYSTEM is commercialized will be subject to the
approval of the DEVELOPMENT COMMITTEE and COMMERCIALIZATION COMMITTEE, not to be
unreasonably withheld.

      2.9 USE OF ANALGESIC DRUG OUTSIDE PAIN MANAGEMENT. The Parties understand
that there may be particular ANALGESIC DRUGS that have utility for indications
outside the 



                                       17
<PAGE>   23
 management of pain. For such an ANALGESIC DRUG that is not under DEVELOPMENT or
commercialization hereunder as a DRUG PRODUCT, Aradigm may bring a written
request to SB to be permitted to develop and market such ANALGESIC DRUG solely
for indication(s) other than pain management. Within [*] of receipt of such
request, SB shall either (a) agree that Aradigm may develop and market such
ANALGESIC DRUG for indications other than pain management, in which case such
ANALGESIC DRUG shall be deemed an "Excluded Drug" hereunder and shall no longer
be within the scope of the definition of ANALGESIC DRUG; or (b) reject Aradigm's
request in writing, in which case such ANALGESIC DRUG may not be developed
independent of this Agreement. For all Excluded Drugs, Aradigm shall use
DILIGENT EFFORTS to develop and commercialize such Excluded Drugs, subject to
the following: Aradigm may develop, market and promote such Excluded Drugs
solely for indications and uses outside of the management of pain, and Aradigm
covenants that it shall not knowingly develop, market, promote or sell products
containing such Excluded Drugs for use in management of pain via pulmonary
delivery of such products, and that it shall contractually require any THIRD
PARTY who develops, markets or otherwise promotes such Excluded Drug by or on
behalf of Aradigm or to Aradigm's benefit, to make the same covenant with
respect to the applicable Aradigm products.

     2.10 [*] In the event that SB obtains data that any [*] substance is or,
based on testing in appropriate models, is likely to be useful in the management
of pain, and provided that such drug substance is not already in development by
Aradigm or its affiliate or licensee, SB may request in writing to the
DEVELOPMENT COMMITTEE that such [*] substance be selected for DEVELOPMENT
hereunder for use in the FIELD for use in the management of pain. Within [*] of
such request, the DEVELOPMENT COMMITTEE shall either (a) select such [*]
substance for DEVELOPMENT in the FIELD hereunder as an ANALGESIC DRUG for use in
the management of pain, in which case the Parties shall appropriately amend the
definition of "ANALGESIC DRUG" to include such [*] substance as an ANALGESIC
DRUG and amend the other terms of the Agreement as necessary to provide for the
DEVELOPMENT and commercialization of such drug hereunder as a DRUG PRODUCT; or
(b) reject SB's request in writing, in which case such [*] substance shall not
be developed under this Agreement unless the DEVELOPMENT COMMITTEE shall
subsequently decide to select such [*] substance for DEVELOPMENT in the FIELD
hereunder as an ANALGESIC DRUG.

3.    REGULATORY FILINGS.

      3.1   APPROVAL APPLICATIONS.

            (a) Except as otherwise provided in this Section 3.1, SB will be
responsible for preparing, assembling and submitting all APPROVAL APPLICATIONS
needed to obtain REGULATORY APPROVAL of AERx SYSTEMS, AERx DEVICES, DRUG
PRODUCTS and ACCESSORIES throughout the TERRITORY, in consultation with and
under the supervision of the DEVELOPMENT COMMITTEE. Such APPROVAL APPLICATIONS
will be owned by and filed [*] Aradigm shall prepare and submit to SB for
inclusion in the APPROVAL APPLICATIONS the materials relating directly to the
AERx

                                       18.
<PAGE>   24
DEVICE and the drug packaging for the DRUG PRODUCT. SB will be responsible for
using DILIGENT EFFORTS to cause such APPROVAL APPLICATIONS to progress through
the approval process throughout the TERRITORY, and Aradigm shall be responsible
for using DILIGENT EFFORTS to support this process.

            (b) Except as otherwise provided below, Aradigm shall be responsible
for preparing and submitting the DRUG MASTER FILES for reference by such
APPROVAL APPLICATIONS, which shall reference the drug master file of the bulk
drug manufacturer of the particular ANALGESIC DRUG in DEVELOPMENT. Aradigm will
grant to SB the right of reference to such DRUG MASTER FILES by the APPROVAL
APPLICATIONS submitted by SB under this Section 3.1. Aradigm will retain
ownership of such DRUG MASTER FILES and all INFORMATION to the extent owned by
Aradigm contained therein. Notwithstanding the foregoing, SB will retain
ownership of all drug master files of SB (or its licensor) and all INFORMATION
contained therein related to the bulk manufacture of SB PROPRIETARY DRUGS, and
Aradigm shall have no right to own any drug master files or INFORMATION related
to any ANALGESIC DRUG that is supplied by or on behalf of SB in accordance with
this Agreement. Aradigm shall have the right to take all permitted measures to
protect the confidentiality of the INFORMATION in such DRUG MASTER FILES. With
respect to DRUG PRODUCTS containing SB PROPRIETARY DRUGS, or that SB is
supplying to Aradigm as permitted herein, SB shall prepare, or obtain a right of
reference to, the drug master file relating to the bulk manufacturing of such
ANALGESIC DRUGS, and shall deliver the same to Aradigm for inclusion in the DRUG
MASTER FILE.

            (c) In the event that the regulatory approval process in any
particular jurisdiction requires a 510(k) application (or equivalent foreign
application) with respect to the AERx DEVICE and/or drug package aspects of the
DRUG PRODUCT of an AERx SYSTEM separate from the NDA applicable to the ANALGESIC
DRUG contained within the applicable DRUG PRODUCT, then Aradigm shall take
responsibility in such situations for preparing and submitting the 510(k) (or
equivalent) applications, and SB shall remain responsible for the related NDAs,
except that it is understood that in those countries in which Aradigm is not
legally permitted to take responsibility for the 510(k) (or equivalent)
applications (e.g., because Aradigm does not have an established office in such
country), then SB shall have responsibility in such countries for filing of such
510(k) (or equivalent) applications, and shall serve as the correspondent with
the FDA or equivalent, but Aradigm shall remain responsible for doing the work
that is required to prepare, pursue approval of and maintain such filing in
accordance with the relevant BUDGET. All such efforts of Aradigm under this
subsection (c) shall be DEVELOPMENT COSTS funded as provided by SB under the
applicable BUDGET.

            (d) In the event SB has any communications or meetings with the FDA
or any other regulatory agency regarding such APPROVAL APPLICATIONS or the
process of seeking or obtaining REGULATORY APPROVAL of a particular PRODUCT, but
only to the extent such communications or meetings relate to approval or
performance of the PRODUCT, SB shall involve Aradigm in preparing for such
communication or meeting and shall give all consideration to Aradigm's concerns
relating thereto, and Aradigm shall be entitled to have one representative (or
such additional number of representatives as the DEVELOPMENT 



                                      19.
<PAGE>   25
COMMITTEE deems appropriate and in accordance with the applicable BUDGET) attend
any such meetings with such agencies, to the extent permitted by such agencies.
SB shall be responsible for all costs and expenses of preparing, submitting and
prosecuting such APPROVAL APPLICATIONS and all fees associated with REGULATORY
APPROVAL of PRODUCTS.

      3.2 ADVERSE EVENTS. The term "Adverse Event" as used in this Section shall
mean any noxious, pathological or unintended adverse change in anatomical,
physiological or metabolic function as indicated by physical signs, symptoms
and/or laboratory changes occurring in clinical trials, post-marketing
surveillance, or clinical practice during use of an AERx SYSTEM, AERx DEVICE,
DRUG PRODUCT or ACCESSORY or published in the medical literature, whether or not
considered causally related to the PRODUCT. The foregoing includes, without
limitation, an exacerbation of a pre-existing condition, intercurrent illness,
drug interaction, significant worsening of a disease under investigation or
treatment, and significant failure of expected pharmacological or biological
action. During the term of the Agreement, each Party shall notify the other of
any information of which such Party becomes aware concerning any Adverse Event
according to the procedure agreed by the Parties as provided below. With respect
to Adverse Events, the following shall apply:

            (a) Promptly after the Effective Date, each Party shall appraise the
other Party of the standard operating procedures for the investigation and
reporting of Adverse Events regarding its products. The Parties shall then
promptly develop and agree upon procedures for the reporting to each other
Adverse Events concerning the PRODUCTS. The Parties shall immediately implement
such agreed procedures and shall provide each other on a regular basis with any
appropriate information which enables the other party to meet its regulatory
obligations in the territories in which it is commercializing or developing
PRODUCTS or which is relevant to the safe use of PRODUCTS. The agreed procedures
will be reviewed jointly on a regular basis or when there is a change in
regulations governing Adverse Events reporting.

            (b) All Adverse Events reports and queries for SB should be
addressed to its central safety department, i.e., Associate Director, Worldwide
Clinical Safety, SmithKline Beecham Pharmaceuticals, New Frontiers Science
Park-South Site, Third Avenue, Harlow, Essex, CM19 5AW, England (facsimile
number 44 1279 644322; telephone number 44 1279 644693) and for Aradigm should
be addressed to its Director, Regulatory Affairs, Aradigm, 26219 Eden Landing
Road, Hayward, CA 94545 (facsimile number (510) 783-0410; telephone number (510)
783-0100), or such other safety representative as may be designated by SB for SB
or by Aradigm for Aradigm.

      3.3 ASSIGNMENT OF APPROVAL APPLICATIONS AND ROYALTY PAYMENT TO SB. No
later than [*] after the expiration of the Agreement under Section 14.1 or the
termination of this Agreement (including termination with respect to particular
countries or a particular AERx SYSTEM) or the termination of SB's rights to a
particular AERx SYSTEM pursuant to Section 2.6, 2.9, 5.5, 14.2 (due to the
uncured breach by SB), or 14.3, SB shall, with respect to each country in which
SB's rights hereunder have terminated, either assign to Aradigm or its designee
or withdraw, at Aradigm's direction as provided in writing to SB, or withdraw 
if 

* Certain information on this page has been omitted and filed
   separately with the Commission. Confidential treatment has
   been requested with respect to the omitted portions.

                                       20.
<PAGE>   26
 Aradigm has not provided SB with such direction or if such assignment is not
legally permissible, all APPROVAL APPLICATIONS submitted and REGULATORY
APPROVALS obtained with respect to the relevant AERx SYSTEMS, AERx DEVICES, DRUG
PRODUCTS and ACCESSORIES subject to such termination in such countries (but
excluding any DRUG PRODUCTS that contain SB PROPRIETARY DRUGS). Thereupon, SB
shall grant Aradigm the irrevocable right of reference with respect to all
clinical data and results owned by SB that arose as a result of work performed
under this Agreement with respect to such PRODUCTS in such countries (excluding
any DRUG PRODUCTS that contain SB PROPRIETARY DRUGS). In addition, promptly
after notice of such expiration or termination, but in any event within [*]
after the effective date of such expiration or termination, SB shall transfer to
Aradigm a copy of all written materials relating to all such APPROVAL
APPLICATIONS and REGULATORY APPROVALS to the extent requested by Aradigm,
including without limitation clinical data packages, application materials, and
Adverse Event reporting materials and databases. Aradigm shall pay SB, within
[*] after receipt of an invoice therefor, SB's actual, out-of-product expenses
in copying and transferring such copies of written materials to Aradigm. During
the period after notice of termination of the AGREEMENT and up to the date of
such termination, SB shall continue to use the same level of efforts SB used
prior to such notice in providing supply to consumers of PRODUCTS, subject to
amounts of the PRODUCT remaining in SB's inventory at the time of such notice
(and including amounts of PRODUCTS added to such inventory due to delivery by
Aradigm of PRODUCTS ordered by SB). In addition, if Aradigm, in a particular
country and with respect to a particular AERx SYSTEM, AERx DEVICE, DRUG PRODUCT
or ACCESSORY, relies on a REGULATORY APPROVAL of SB to continue marketing the
AERx SYSTEM, AERx DEVICE, DRUG PRODUCT or ACCESSORY (if already approved in the
country), or relies on the data and information in an APPROVAL APPLICATION
relating to such PRODUCT to obtain REGULATORY APPROVAL in such country to
commercialize the PRODUCT, then Aradigm will pay SB a royalty equal to [*] of
Aradigm's, its AFFILIATES' and its and their licensees' net sales of such AERx
SYSTEM, AERx DEVICE, DRUG PRODUCT or ACCESSORY in such country. Aradigm's and
its AFFILIATES' and licensees' "net sales" of such PRODUCTS shall be calculated
in a manner consistent with the calculation of NET SALES as provided herein.

4.    MILESTONE PAYMENTS.

      4.1 INITIAL MILESTONE PAYMENTS. In partial consideration for the licenses
granted to SB in the Agreement under PATENTS and INFORMATION, SB shall pay
Aradigm the following amounts in U.S. Dollars within the specified time period
after the occurrence of the specified events:

            (a) $9.0 million due upon the Effective Date subject to expiration
of the waiting period under the Act as provided in Section 15.1, such payment to
be made within five (5) business days after the HSR Approval Date, as such term
is defined in Section 15.1;

            (b) [*] within thirty (30) days after INITIATION of the first PHASE
II TRIAL under this Agreement of the INITIAL PRODUCT.

* Certain information on this page has been omitted and filed
  separately with the Commission. Confidential treatment has
  been requested with respect to the omitted portions.


                                       21.
<PAGE>   27

For clarity, no payment shall be owed under this Section 4.1 if the milestone
event is not achieved during the term of the Agreement prior to the receipt of
the notice of termination from the terminating Party by the receiving Party.

      4.2 MILESTONE PAYMENTS FOR CERTAIN DEVELOPMENT EVENTS. As additional
consideration for the licenses granted to SB in the Agreement under PATENTS and
INFORMATION, SB shall pay Aradigm the following amounts in U.S. Dollars within
thirty (30) days after the occurrence of the specified events:

            (a) [*] upon INITIATION of the first PHASE III TRIAL under this
Agreement of an AERx SYSTEM;

            (b) [*] upon the filing of the first APPROVAL APPLICATION filed
under this Agreement with the FDA or its equivalent for an AERx SYSTEM in the
U.S.A., Japan, or any three of the five MAJOR MARKET COUNTRIES located in
Europe ; and

            (c) [*] upon the first REGULATORY APPROVAL for an AERx SYSTEM in [*]

For avoidance of doubt, it is agreed that the above milestone payments shall be
made just once with respect to achievement of any particular milestone event by
the first AERx SYSTEM to achieve such milestone, regardless of the number of
times such milestone event may be achieved by such AERx SYSTEM or any other AERx
SYSTEM. For clarity, no payment shall be owed under this Section 4.2 if the
milestone event is not achieved during the term of the Agreement prior to the
receipt of the notice of termination from the terminating Party by the receiving
Party.

      4.3 MILESTONE PAYMENTS FOR ADDITIONAL SYSTEMS. As used herein, the term
"Additional AERx SYSTEM" shall mean an AERx SYSTEM under DEVELOPMENT pursuant to
this Agreement that contains an ANALGESIC DRUG that is a different Active
Ingredient (as defined below) from that utilized in the DRUG PRODUCT in an AERx
SYSTEM for which the milestone payments under Section 4.2 or this Section 4.3
have been paid by SB. For purposes of this Section, the term "Active Ingredient"
shall mean the actual chemical compound that is the ANALGESIC DRUG in a DRUG
PRODUCT. A prodrug, metabolite, ester, salt, hydrate, solvate, polymorph or
isomer (each, a "Related Compound") of a particular Active Ingredient shall not
be considered a different "Active Ingredient" from such Active Ingredient with
respect to DEVELOPMENT of a DRUG PRODUCT containing such Related Compound,
provided that the DEVELOPMENT COMMITTEE agrees that the DEVELOPMENT efforts
needed to achieve REGULATORY APPROVAL of such DRUG PRODUCT and the related AERx
SYSTEM shall be substantially less than the typical DEVELOPMENT efforts required
for a DRUG PRODUCT containing an entirely different chemical entity. However,
notwithstanding the foregoing it is agreed that morphine acetate is a different
Active Ingredient from morphine sulfate. As additional consideration for the
licenses granted to SB in the Agreement under PATENTS and INFORMATION, for each
such Additional AERx SYSTEM, the following milestones payments

shall be paid in U.S. Dollars within thirty (30) days after the occurrence of
the specified events according to the following schedule, unless otherwise
agreed by the Parties:

            (a) [*] upon INITIATION of the first PHASE I TRIAL under this
Agreement for such Additional AERx SYSTEM;

            (b) [*] upon INITIATION of the first PHASE III TRIAL under this
Agreement for such Additional AERx SYSTEM;

            (c) [*] upon filing of the first APPROVAL APPLICATION under this
Agreement with the FDA or its equivalent covering such Additional AERx
SYSTEM in [*] and

            (d) [*] upon the first REGULATORY APPROVAL of such Additional
AERx SYSTEM in [*].

For avoidance of doubt, for any such Additional AERx SYSTEM, it is agreed that
the above milestone payments shall be made just once with respect to achievement
of any particular milestone event by such Additional AERx SYSTEM, regardless of
the number of times such milestone event may be achieved by such AERx SYSTEM.
For clarity, no payment shall be owed under this Section 4.3 if the milestone
event is not achieved during the term of the Agreement prior to the receipt of
the notice of termination from the terminating Party by the receiving Party.
Further, it is agreed that, with respect to any such Additional AERx SYSTEM for
which milestones hereunder are being or have been paid, a DRUG PRODUCT
containing a different dose or strength of the same ANALGESIC DRUG as is
contained in such Additional AERx SYSTEM, or that is in DEVELOPMENT for a
different labeled indication than that for which such Additional AERx SYSTEM was
in DEVELOPMENT, shall not constitute a separate "Additional AERx SYSTEM" for
which milestone payments hereunder must be made beyond the payments made for
milestone events achieved by such additional AERx SYSTEM.

      4.4 ADDITIONAL PAYMENT CONDITIONS. With respect to milestone payments owed
under either Section 4.2 or 4.3, the following shall be applicable:

            (a) In the event that a particular DRUG PRODUCT and the related AERx
DEVICE are subject to separate APPROVAL APPLICATIONS (e.g., because the AERx
DEVICE may be approved under a 510(k) application separate from the NDA for the
DRUG PRODUCT), the particular milestone payments owed under Section 4.1 or 4.2,
as applicable, in such situation for filing of APPROVAL APPLICATIONS and receipt
of REGULATORY APPROVALS shall be owed when the particular milestone event has
been achieved by both the DRUG PRODUCT and the AERx DEVICE in DEVELOPMENT.

            (b) Upon the first REGULATORY APPROVAL for an AERx SYSTEM [*] at 
such time as one of the following conditions has been met:

V.P. and Director, WSO, such [*] SB and Aradigm each agrees to use DILIGENT
EFFORTS to achieve [*] prior to the first REGULATORY APPROVAL of an AERx SYSTEM.

5.    DISTRIBUTION LICENSE AND MARKETING.

      5.1 DISTRIBUTION LICENSE. Subject to compliance with the terms of this
Agreement, Aradigm hereby grants SB the exclusive license under the ARADIGM
PATENTS and the INFORMATION owned or CONTROLLED by Aradigm and provided to SB
under this Agreement to use, import, market, offer for sale and sell, solely in
the TERRITORY and solely for use in the FIELD, the AERx SYSTEMS, AERx DEVICES,
DRUG PRODUCTS and ACCESSORIES that were either (i) purchased from Aradigm
hereunder or (ii) manufactured pursuant to the permitted exercise of the Back-Up
License granted to SB under Section 6.6(c). SB may sublicense such license
rights to its AFFILIATES. SB may sublicense such license rights to THIRD PARTIES
in any MAJOR MARKET COUNTRY only to the extent permitted by Aradigm in writing,
which approval shall not be unreasonably withheld, and may freely sublicense
such rights to THIRD PARTIES in any other country in the TERRITORY. Aradigm
shall not develop the AERx SYSTEMS, AERx DEVICES, and DRUG PRODUCTS for any use
outside the FIELD; provided that the foregoing shall not be interpreted to
prevent Aradigm or its AFFILIATES or THIRD PARTY licensees from developing or
having developed its other AERx pulmonary drug delivery devices for any use
outside the FIELD. Unless otherwise agreed by the Parties in writing, SB is not
licensed hereunder to, and SB covenants that it shall not knowingly, develop,

DEVICES, DRUG PRODUCTS and ACCESSORIES for any use or utility outside the FIELD
or in any country outside the TERRITORY.

      5.2 GRANT BACK LICENSE. SB hereby grants Aradigm a royalty-free,
worldwide, nonexclusive license under the SB PATENTS to manufacture, import,
use, market and sell pulmonary delivery products; provided, however that during
the term of this Agreement, the foregoing license shall not include or cover
pulmonary delivery or any other use of any SB PROPRIETARY DRUG except to the
extent that such drug is an ANALGESIC DRUG under DEVELOPMENT or being
commercialized as part of a DRUG PRODUCT under this Agreement, and that after
expiration or termination of this Agreement, the foregoing license shall not
include or cover the manufacture, import, use, marketing or sale of any SB
PROPRIETARY DRUG for pulmonary delivery or any other use.

      5.3 OVERALL MANAGEMENT OF COMMERCIALIZATION EFFORTS. Promptly after the
INITIATION of PHASE III TRIALS on the first AERx SYSTEM, the Parties shall form
the COMMERCIALIZATION COMMITTEE constituted of an equal, agreed-on number of
representatives from each Party. The COMMERCIALIZATION COMMITTEE shall meet
regularly, at least once each quarter thereafter during the Agreement. Such
meetings shall take place at an SB location in the U.S.A. or, if requested by
either Party, via telephone or video teleconference. The COMMERCIALIZATION
COMMITTEE shall oversee all activities of the Parties under this Agreement
relating to commercialization and marketing of PRODUCTS, including coordinating
the overall strategy for the commercialization of PRODUCTS and preparing for the
launch of PRODUCTS. The COMMERCIALIZATION COMMITTEE shall: (i) review the
Marketing Plans and appropriate amendments thereto; (ii) be the primary contact
point between the Parties regarding the transfer of INFORMATION and the
discussion of efforts to conduct marketing of PRODUCTS; (iii) review PRODUCT
marketing success and formulate strategies to address issues with PRODUCT
commercialization; (iv) select the countries, in addition to the MAJOR MARKET
COUNTRIES, in which to conduct DEVELOPMENT and commercialization of the AERx
SYSTEMS; and (v) evaluate commercial opportunities for additional new PRODUCTS.
Each Party may appoint its representatives to the COMMERCIALIZATION COMMITTEE.
The members of the project teams shall meet and otherwise communicate as
frequently as appropriate to carry out the objectives of the Marketing Plans.
The COMMERCIALIZATION COMMITTEE shall operate by unanimous decision of its
members, and the members of the COMMERCIALIZATION COMMITTEE shall make a good
faith effort to reach decisions on all matters before the committee; provided,
however, that it is understood that [*] members on the COMMERCIALIZATION
COMMITTEE. All expenses of Aradigm in attending COMMERCIALIZATION COMMITTEE
meetings shall be borne by Aradigm.

      5.4 MARKETING PLANS. At least [*] prior to the expected commercial launch
of an AERx SYSTEM in any country, SB shall provide Aradigm's representatives on
the COMMERCIALIZATION COMMITTEE with a copy of the SB's draft marketing plan for
such AERx SYSTEM and components thereof in such country for Aradigm's review and
comment.

Thereafter, on an annual basis, in accordance with the timing within SB's
internal practices and procedures for producing marketing plans, SB shall
provide Aradigm with its marketing plan for such PRODUCT for the following year,
for Aradigm's review and comment. Such marketing plans shall also include SB's
projected sampling of each AERx SYSTEM, AERx DEVICE, DRUG PRODUCT, and ACCESSORY
(if legally permissible) during the following year. Aradigm shall treat all such
marketing plans as SB's CONFIDENTIAL INFORMATION. SB shall consider in good
faith all Aradigm's reasonable suggestions or concerns regarding such SB
marketing plans. In connection with the development of a commercialization
strategy for the AERx SYSTEMS and components thereof, SB will give consideration
to making appropriate use of the distribution capabilities that Aradigm is
establishing for its other pulmonary delivery products for distribution of the
AERx DEVICE, provided that nothing herein shall be construed to mean that SB
shall be under any obligation to use such distribution capabilities. Subject to
the foregoing, and to compliance with Section 5.5, all decisions regarding
marketing, promotion and sales of each AERx SYSTEM, AERx DEVICE, DRUG PRODUCT,
and ACCESSORY throughout the TERRITORY by or on behalf of SB shall be at SB's
sole discretion.

      5.5   MARKETING DILIGENCE.

            (a) SB and its AFFILIATES shall use DILIGENT EFFORTS to market and
sell each AERx SYSTEM that has received REGULATORY APPROVAL in all countries in
the TERRITORY where such REGULATORY APPROVAL has been granted. Without limiting
the generality of the foregoing, SB agrees to launch sales of the AERx SYSTEM in
each such country within [*] of the date SB obtains REGULATORY APPROVAL in such
country which approval includes any required pricing approval that is granted at
a price that is, in SB's judgment, reasonably exercised, commercially viable. In
addition, there shall be a presumption that SB has failed to use DILIGENT
EFFORTS in conducting marketing of an AERx SYSTEM if for a continuous period of
[*] at any time following launch of commercial sales of such AERx SYSTEM in a
country, no sales of the AERx SYSTEM or its component AERx DEVICE, DRUG PRODUCT
or ACCESSORIES are made in such country; provided that such event is not
directly caused by an event of force majeure (but only for so long as SB uses
DILIGENT EFFORTS to end the effects of such event of force majeure). If SB
breaches the foregoing requirements in a particular country, and fails to cure
such breach within [*] days of written notice thereof from Aradigm, then Aradigm
may terminate SB's rights hereunder in such country with respect to such AERx
SYSTEM upon written notice provided to SB no later than ninety (90) days after
the end of such [*] day period, but provided that SB has not cured such breach
prior to Aradigm's giving such notice of termination.

            (b) In addition to the obligations under subsection (a), SB shall,
in order to [*] according to the following schedule, which [*]

provided, however, that if [*] in the geographical areas of (i) the U.S.A., (ii)
Japan, or (iii) [*] in Europe, then the foregoing obligation [*] shall be
[*] for each of such geographical areas (i.e., as listed in (i), (ii)
or (iii)) in which such [*] In addition, the foregoing obligation to [*] shall
be [*], but only during the period of
time in which such circumstances continue to exist:

            (1) an event of force majeure (as defined in Section 15.7) has
      occurred that prevents or impedes SB from making sales of the INITIAL
      PRODUCT or its related AERx DEVICES or DRUG PRODUCTS, but only so long as
      the effects of such event continue and so long as SB continues to make
      DILIGENT EFFORTS to end the effects of such event of force majeure; or

            (2) Aradigm has committed a breach of its obligation to supply SB
      with INITIAL PRODUCT or its related AERx DEVICES or DRUG PRODUCTS and such
      breach has caused SB to be unable to meet a substantial amount of existing
      orders for any such PRODUCTS, but only so long as the effects of such
      breach continue such that SB's sales of such affected PRODUCTS, as
      measured during any [*] of such PRODUCTS for the three month period
      directly prior to the date of such breach; or

            (3) SB is manufacturing PRODUCTS pursuant to the permitted exercise
      of the Back-Up License under the provisions of Section 6.6(c), but only so
      long as SB continues to have the right to exercise such manufacturing
      license.

During any period in which [*] under this Section 5.5(b) is [*] as
provided above, the [*] shall also be [*], such that the aggregate length
of time for which SB shall have the obligation to [*] subject to earlier
termination of the Agreement. In the event that SB's right to commercialize
PRODUCTS is terminated in the U.S.A., the [*] shall be reduced as provided
above, and such [*] in Japan or at least [*] in Europe. In the event SB 
[*] hereunder, Aradigm may give SB written notice of such [*], and if SB has
not cured such [*] within [*] of such notice, Aradigm may then [*] by
written notice provided no later than [*] after the end of such cure period.

            (c) The COMMERCIALIZATION COMMITTEE shall use DILIGENT EFFORTS to
determine which countries (in addition to the MAJOR MARKET COUNTRIES) to select
pursuant to Section 5.3 for DEVELOPMENT and commercialization of the AERx
SYSTEMS. Countries in the world may be excluded from the TERRITORY as provided
below.

                  (i) If the COMMERCIALIZATION COMMITTEE determines that SB will
not commercialize any AERx SYSTEMS in a particular country, either itself or
through an AFFILIATE or sublicensee, the COMMERCIALIZATION COMMITTEE shall give
Aradigm written notice of such determination promptly after such determination,
and upon such notice all SB's right to distribute all PRODUCTS in such country
shall immediately terminate, except as otherwise provided in subsection (iii)
below, and thereafter such country shall be excluded from the definition of
"TERRITORY" and Aradigm shall have the right to distribute, market and sell the
PRODUCTS in such country and to license others to do so, except that Aradigm
shall have no such right with respect to a DRUG PRODUCT which contains an SB
PROPRIETARY DRUG.

                  (ii) If by the date that is [ * ] after the [ * ] in a MAJOR
MARKET COUNTRY, the COMMERCIALIZATION COMMITTEE has not selected a particular
country for commercialization of the AERx SYSTEMS, and the Parties have not
commenced DILIGENT EFFORTS [*] in such country, then immediately upon written 
notice provided by Aradigm after such date (but subject to the dispute 
resolution provisions of Section 13.1 in the event that SB contends that the 
foregoing requirements are not met), and except as otherwise provided 
in subsection (iii) below, all SB's right to distribute AERx SYSTEMS, 
AERx DEVICES, ACCESSORIES and DRUG PRODUCTS in such country shall immediately 
terminate, and thereafter such country shall be excluded from the definition 
of "TERRITORY" and Aradigm shall have the right to distribute, market and sell
the AERx SYSTEMS and DRUG PRODUCTS in such countries and to license others to 
do so, except that Aradigm shall have no such right with respect to a DRUG 
PRODUCT which contains an SB PROPRIETARY DRUG.

                  (iii) Notwithstanding the provisions of subsections (i) and
(ii) above, if SB has launched PRODUCTS in at least [ * ] in Europe within [ * ]
after the first REGULATORY APPROVAL of an AERx SYSTEM in a MAJOR MARKET COUNTRY,
then the COMMERCIALIZATION COMMITTEE may elect not to launch the PRODUCTS, or to
cease commercialization of PRODUCTS, in any country of the European Union, so
long as SB continues to commercialize the PRODUCTS in at least [ * ] in Europe,
and such election shall not trigger the rights of Aradigm under subsection (ii)
above with respect to such other countries. Similarly, if SB has launched
PRODUCTS in the U.S.A. within [ * ] after the first REGULATORY APPROVAL of an
AERx SYSTEM in a MAJOR MARKET COUNTRY, then the COMMERCIALIZATION COMMITTEE may
elect not to launch the PRODUCTS, or to cease commercialization of PRODUCTS, 
[ * ] and such election shall not trigger the rights of Aradigm under subsection
(ii) above with respect to [ * ] However, if SB has not launched the PRODUCTS
in at least [ * ]

[*] in Europe within [*] after the first REGULATORY APPROVAL of an 
AERx SYSTEM in a MAJOR MARKET COUNTRY, then all countries in the European 
Union shall be excluded from the definition of "TERRITORY" and Aradigm 
shall have the right to distribute, market and sell the AERx SYSTEMS and 
DRUG PRODUCTS in such countries and to license others to do so, except 
that Aradigm shall have no such right with respect to a DRUG PRODUCT which 
contains an SB PROPRIETARY DRUG.

      5.6 REPORTS. Commencing after the first commercial sale of a PRODUCT in
any country, SB will provide to Aradigm a report on a quarterly basis within
forty-five (45) days of the end of such calendar quarter summarizing SB's, its
AFFILIATES' and sublicensees' marketing efforts and containing a true and
accurate accounting of quarterly sales, including calculations of NET SALES
itemized by PRODUCT and by country, with respect to the PRODUCTS sold during
such period, and the corresponding royalty payments due Aradigm pursuant to
Section 7.3.

      5.7 PACKAGING AND LABELING. The PRODUCTS for commercial sale under this
Agreement shall be packaged by Aradigm and labeled consistent with the
requirements of the regulatory authorities in the country in which it will be
sold, and where legally permissible, shall identify any applicable ARADIGM
PATENTS consistent with marking requirements, and shall identify Aradigm as the
manufacturer of the PRODUCTS and SB as the distributor of such PRODUCTS. Subject
to the foregoing and to compliance with Section 9.10, SB shall in its reasonable
discretion determine the packaging and labeling for the PRODUCTS for resale
hereunder.

      5.8   RESTRICTIVE COVENANTS.

            (a) SB OBLIGATIONS. During the term of the Agreement, SB and its
AFFILIATES shall not market or sell any products [ * ] covered by this
Agreement in any countries of the TERRITORY. Notwithstanding the foregoing, SB
shall retain the right to develop, market and sell, or to have THIRD PARTIES
develop, market and sell in [ * ] all countries.

            (b) ARADIGM OBLIGATIONS. During the term of this Agreement, except
as otherwise permitted in Section 2.9, Aradigm and its AFFILIATES shall not (i)
manufacture or sell any products, or license any THIRD PARTY to manufacture or
sell any products, [ * ] covered by this Agreement; or (ii) manufacture or sell,
or license any THIRD PARTY to manufacture or sell, in any countries in the
TERRITORY any pulmonary inhalation drug products that (1) are similar in
function and performance to the AERx SYSTEM, (2) are [ * ] Aradigm or such
licensee specifically for the treatment of cancer pain or post-operative pain,
and (3) have analgesic efficacy comparable to DRUG PRODUCTS for use in treating
cancer pain or post-operative pain. Except as expressly provided in subsection
(ii) in the foregoing, Aradigm and its AFFILIATES shall retain the right to

develop, market and sell, any and all products (other than AERx DEVICES and DRUG
PRODUCTS) for use outside the FIELD in all countries, but subject to Section
5.1. For clarification, the foregoing shall not be interpreted to prevent
Aradigm from developing, using, making and selling other of its AERx pulmonary
drug delivery systems for use outside the FIELD, except to the extent expressly
provided in subsection (ii) in the foregoing.

      5.9 RESTRICTIONS ON DISTRIBUTORS AND DEALERS. SB shall require that its
AFFILIATES, and all its non-AFFILIATE distributors or dealers to whom SB or its
AFFILIATES sell the PRODUCTS for resale, shall not knowingly market, promote,
advertise or sell the PRODUCTS for any use other than use in the FIELD or in any
country or territory outside the TERRITORY, subject to compliance with any
applicable laws or governmental regulations. Except as otherwise permitted in
Section 2.10, Aradigm shall require that its AFFILIATES, and all its
non-AFFILIATE distributors or dealers to whom Aradigm or its AFFILIATES sell any
pulmonary inhalation devices, packets containing drugs for use in such pulmonary
inhalation devices, or accessories therefor, including, but not limited to, any
AERx pulmonary drug delivery devices, for use outside the FIELD, shall not
knowingly market, promote or advertise use of such devices, packets or
accessories for use in the FIELD, and, to the extent the TERRITORY is less than
the entire world, shall not knowingly market or sell any PRODUCTS for use in the
TERRITORY, subject to compliance with any applicable laws or governmental
regulations.

6.    MANUFACTURING AND SUPPLY.

      6.1 MANUFACTURING RIGHTS. Subject to Section 6.6, Aradigm shall retain all
rights to manufacture or have manufactured the AERx SYSTEMS, AERx DEVICES, DRUG
PRODUCTS and ACCESSORIES. Aradigm agrees to supply the clinical trial
requirements for the AERx DEVICES, DRUG PRODUCTS, placebos (in AERx unit
packets), and ACCESSORIES used in clinical DEVELOPMENT and SB's, its AFFILIATES,
and its sublicensees' requirements in the TERRITORY for all PRODUCTS for
promotional use in the FIELD and for commercial sale for use in the FIELD,
pursuant to the supply terms provided below.

      6.2 BULK DRUG SUBSTANCE. Subject to the following, Aradigm shall be
responsible for securing a supply of bulk ANALGESIC DRUGS for inclusion in DRUG
PRODUCTS. Such supply will be obtained from suppliers holding current drug
establishment registrations and DRUG MASTER FILES with FDA and similar foreign
regulatory agencies and appropriate current licenses from the U.S. Drug
Enforcement Administration and from similar foreign regulatory agencies. In the
event that SB can obtain the bulk supply of a particular ANALGESIC DRUG on terms
more favorable than Aradigm is able to obtain, then SB may contract to obtain
the bulk supply to be provided to Aradigm at SB's cost; provided that if SB
obtains such bulk supply pursuant to a contractual arrangement with the supplier
that grants SB exclusive rights to such supply, SB covenants that [ * ] in the
event of termination of this Agreement in its entirety pursuant to Section 2.6,
5.5, 14.2 (due to the uncured breach by SB), or 14.3, and provided further
that if the Agreement terminates as to

specific countries, pursuant to Sections 2.6 or 5.5, then [*] such bulk
ANALGESIC DRUGS as [*] in order to commercialize the AERx SYSTEMS in such
countries, except that, notwithstanding the above, [*] any ANALGESIC DRUG that
is covered by a PATENT owned or controlled by SB or its AFFILIATE.

      6.3   CLINICAL SUPPLY. Aradigm agrees to provide for use by the Parties
such quantities of the AERx DEVICE, ACCESSORIES, DRUG PRODUCT and placebos (in
AERx unit packets), required for conducting preclinical and clinical
DEVELOPMENT, as the DEVELOPMENT COMMITTEE provides under the applicable
DEVELOPMENT PLAN. Clinical supplies of the DRUG PRODUCT under DEVELOPMENT (and
placebo if required) shall be formulated and packaged as determined by the
DEVELOPMENT COMMITTEE for use with AERx DEVICE in the clinical trials to be
conducted under this Agreement. The forecast of such DEVELOPMENT requirements
for such PRODUCTS shall be contained within the relevant DEVELOPMENT PLAN, as
updated in accordance with Section 2.3. Aradigm shall use such forecasts and
updates to prepare the manufacturing of such requirements of the PRODUCTS (and
placebo) for preclinical and clinical use for the next four (4) calendar
quarters. Aradigm shall supply the quantities of the AERx DEVICES, ACCESSORIES,
DRUG PRODUCTS and placebos for use in clinical trials at the delivery times
outlined in the relevant DEVELOPMENT PLAN; provided, however, that such delivery
times are not less than [*] days after the most recent update of such
requirements as outlined in the relevant DEVELOPMENT PLAN. To the extent
possible, the DEVELOPMENT COMMITTEE shall use good faith efforts to ensure that
each update of the DEVELOPMENT requirements in a particular DEVELOPMENT PLAN
shall not deviate, with respect to any particular item, by more than [*] from
the amount of such item forecasted to be required in the most recent previous
forecast. Notwithstanding the foregoing, if unanticipated changes arise that
result in an increase by more than [*] from the amount of such PRODUCT
previously forecasted to be required, in the quantity requirements of AERx
DEVICES, ACCESSORIES, DRUG PRODUCTS and/or placebos required for DEVELOPMENT
under the applicable trial protocol, Aradigm will use DILIGENT EFFORTS to
fulfill the requirements in excess of [*] of the forecasted requirements,
subject to its other business obligations. Shipment, delivery and acceptance of
AERx DEVICES, ACCESSORIES, DRUG PRODUCTS and placebos shall be in accordance
with Sections 6.8 and 6.10 of this Agreement. Reimbursement to Aradigm for
supplying PRODUCTS and placebos under this Section 6.3 shall be as provided in
Section 7.1.

      6.4   COMMERCIAL PRODUCT SUPPLY. Aradigm agrees to provide SB with its
commercial requirements of the AERx SYSTEMS, AERx DEVICES, DRUG PRODUCTS and
ACCESSORIES for which REGULATORY APPROVAL has been obtained, in FINISHED FORM
pursuant to the following terms.

      6.5   FORECASTING AND ORDERING MECHANISMS.

            (a) At such time after the Effective Date that Aradigm [*] Aradigm
shall provide to SB such INFORMATION in Aradigm's CONTROL relating to Aradigm's
PRODUCT

manufacturing steps and timing, and in particular with respect to lead times
Aradigm requires to achieve manufacture of PRODUCTS on a commercial scale
hereunder, as SB reasonably requires in order to determine appropriate
procedures and mechanisms for providing to Aradigm forecasts of SB's (and its
AFFILIATES' and sublicensees') requirements for PRODUCTS to be ordered and
purchased hereunder, and for ordering such requirements. SB shall review such
INFORMATION promptly after receipt, and appropriate representatives from SB and
Aradigm shall then meet to determine the appropriate forecasting, ordering and
inventory mechanisms that will be used by the Parties for ordering and supplying
the commercial requirements of PRODUCTS hereunder. Such forecasting, ordering
and inventory mechanisms shall be set forth in a writing, and upon mutual
execution of such writing by the Parties, such mechanisms (the "Supply
Procedures") shall become part of this Agreement.

      (b) With respect to the forecasting mechanism, such Supply Procedures
shall provide: (i) that within an agreed period of time prior to the first
expected REGULATORY APPROVAL of an AERx SYSTEM, SB shall provide a good faith
estimate of its expected requirements, on a per quarter basis, for each
particular PRODUCT in the AERx SYSTEM to be ordered for an agreed period before
and an agreed period after the AERx SYSTEM launch; (ii) as of an agreed time
before the first expected REGULATORY APPROVAL of a particular AERx SYSTEM, SB
shall provide Aradigm a rolling 12 month forecast for SB's expected orders for
each particular PRODUCT during each month during such 12 month period; (iii) SB
shall provide Aradigm updated forecasts for expected orders of PRODUCTS at
agreed intervals of time; (iv) that in each forecast provided, the forecasted
orders for an agreed time period for each forecasted PRODUCT shall constitute
binding orders by SB for such PRODUCTS, to be placed during such agreed time
period; and (v) that the amount by which the forecasted orders for each PRODUCT
in a particular forecast delivered to Aradigm may not deviate by more than [*]
from the forecast for orders for such PRODUCTS in the most recent previous
forecast submitted to Aradigm. Such forecasting mechanism in the Supply
Procedures shall also provide that SB may make a written request that Aradigm
permit the binding order to deviate from the limitations that are established in
the Supply Procedures, which request Aradigm will reasonably consider.

            (c) With respect to the ordering mechanism, such Supply Procedures
shall provide: (i) that SB or its AFFILIATES shall place orders for the PRODUCTS
to be supplied under the Agreement on SB's standard purchase order form,
specifying the quantity of each specific PRODUCT ordered and the requested
delivery date, which shall not in any event be sooner or later than agreed time
period(s) from the date of such purchase order; (ii) that to the extent any
purchase order, invoice or acknowledgment form used by SB contains any
provisions additional or contrary to the provisions of this Agreement, such
additional or contrary provision shall have no force or effect and the terms of
this Agreement shall control; (iii) that Aradigm shall not be obligated to
supply any amounts of a particular PRODUCT in such order more than an agreed
percentage of the unit quantity of such PRODUCT specified in the binding
forecast for the applicable time period; (iv) that SB's orders for a PRODUCT may
not be less than an agreed percentage of the binding forecast for such PRODUCT
for the applicable time period; (v) that Aradigm agrees that it will use
DILIGENT EFFORTS to provide additional amounts of a particular PRODUCT, beyond

            (d) The Supply Procedures shall also establish an inventory
mechanism for PRODUCTS, which shall provide that (i) within an agreed period of
time after the commercial launch of a particular AERx SYSTEM, Aradigm shall use
DILIGENT EFFORTS to maintain an inventory of the PRODUCT in such AERx SYSTEM at
least equal to the written forecast for purchases of such product to be made
during an agreed number months in the most recent forecast provided to Aradigm
by SB under the forecasting mechanism of the Supply Procedures, with the
understanding that such agreed number of months must take into account stability
considerations; (ii) SB shall maintain an inventory of all PRODUCTS in
accordance with SB's normal practices, and shall give Aradigm quarterly updates
of the extent of such inventory; (iii) each Party's inventory of PRODUCTS and/or
components maintained under such inventory mechanism shall only be permitted to
fall below the levels established in subsection (i) above in the event that SB
submits orders in excess of the forecasted amounts or Aradigm experiences
manufacturing or supply problems with respect to the PRODUCTS; (iv) Aradigm
shall use DILIGENT EFFORTS in accordance with Aradigm's normal practices to
promptly replenish any inventory of a PRODUCT that is depleted in satisfying
purchases of the PRODUCT by SB hereunder; and (v) Aradigm's inventory of
PRODUCTS as required under the Supply Procedures shall be maintained by Aradigm
at no charge to SB.

            (e) The Parties further agree that if the foregoing forecasting,
ordering or inventory mechanisms established in the Supply Procedures are
determined by the Parties, in good faith cooperation and giving reasonable
consideration to each Party's economic and business needs, to be inappropriate
given the then-existing manufacturing and supply circumstances regarding
PRODUCTS hereunder, the Parties will discuss in good faith appropriate
amendments to the applicable mechanisms in the Supply Procedures.

      6.6 RESOLUTION OF SUPPLY PROBLEMS. Problems with respect to inability of
Aradigm to supply on a timely basis PRODUCTS ordered by SB in compliance with
this Agreement shall be addressed as provided below.

            (a) If [*] that Aradigm will not be able to supply to SB [*] most
recent orders and/or binding forecasts of orders for a particular PRODUCT
submitted by SB in accordance with the Supply Procedures, Aradigm shall
immediately notify SB in writing of such determination, which notice shall
provide SB with the details on the extent of the expected shortfall of supply,
the causes of such inability to supply, and Aradigm's proposed solution to the
problem. Upon such notice of a supply problem, or in any event upon Aradigm's
failure to satisfy, within the delivery time frame specified by SB consistent
with the Supply Procedures, a portion of the PRODUCTS ordered by SB in
compliance with this Agreement, but provided that such supply problem or failure
cannot be satisfied or addressed by SB's and Aradigm's existing inventories for
such PRODUCTS and will cause an interruption in the supply of such PRODUCTS by
SB or its AFFILIATES to the commercial market for [*] then SB and Aradigm will

agreed amount of such PRODUCTS to cover the shortfall in supply, with Aradigm
continuing to supply an agreed amount of such PRODUCTS. [*] to the supply
problem will be [*].

            (b) If the Parties cannot reach agreement on an appropriate
resolution to the supply problem within [*] of commencing such discussions under
subsection (a) above, senior management representatives of the Parties will
immediately meet to discuss in good faith the problem in an effort to reach
agreement on such resolution. As part of such discussions, Aradigm shall make
[*] during the period when such supply problem with respect to such PRODUCTS is
expected to continue. Any agreed resolution by the Parties to the supply problem
will be set forth in a writing executed by both Parties. If, despite good faith
efforts, the senior management officials are unable to reach agreement on such
resolution of the supply problem within [*] of their commencing such
discussions, then at SB's written request provided to Aradigm no more than [*]
thereafter, the Parties will proceed as provided in subsection (c) below.

            (c) If there is a PRODUCT supply problem subject to the provisions
of subsections 6.6(a) and (b) above, and (1) the [*] resolution of such problem

subsection (b), or (2) Aradigm has failed to meet to discuss the problems as
required above, then at SB's written request provided to Aradigm no more than
[*] SB shall be permitted to exercise the license granted in the following
sentence. Subject to all other obligations of the Agreement, Aradigm hereby
grants to SB a co-exclusive license (the "Back-Up License"), under relevant
ARADIGM PATENTS and INFORMATION owned or CONTROLLED by Aradigm, as necessary to
permit SB to make or have made only the PRODUCT that is the subject of such
supply problem that was not resolved by the Parties, solely for sale in the
TERRITORY for use in the FIELD under this Agreement. However, SB covenants,
represents and warrants that SB shall not exercise the Back-Up License unless
and until the conditions specified in the first sentence of this Section 6.6(c)
have been completely satisfied. In the event that SB is permitted to exercise
the Back-Up License, then SB shall have the right to grant one sublicense under
the Back-Up License to a THIRD PARTY, solely for the period in which SB's right
to exercise the license hereunder exists, and provided further that [*]
Immediately upon SB's written request hereunder to exercise the Back-Up License,
Aradigm shall transfer to SB copies of all INFORMATION, including technical
information, that is owned or Controlled by Aradigm, relates to the manufacture
of the PRODUCT that is the subject of the Back-Up License and is reasonably
necessary to enable SB to manufacture such PRODUCT. Thereafter, but only during
the period when SB is permitted hereunder to exercise the Back-Up License, SB
shall be permitted access to and a right of reference to the DRUG MASTER FILES
and any APPROVAL APPLICATIONS held in Aradigm's name for the PRODUCTS that are
the subject of such Back-Up License. Aradigm shall provide SB reasonable
assistance, at SB's request and SB's expense, with respect to understanding such
manufacturing INFORMATION and practicing the Back-Up License.

<PAGE>   40

Notwithstanding the grant of the Back-Up License, Aradigm shall continue to
utilize its DILIGENT EFFORTS to continue to supply to SB amounts of the affected
PRODUCT ordered by SB hereunder.

      Any exercise of the Back-Up License by SB under this subsection (c) shall
be subject to compliance by SB with the following:

                  (i) With respect to the PRODUCT that was the subject of the
supply problem and is covered by the Back-Up License, [*] the amounts of such
PRODUCT that [*] as provided in subsection (b) above, during the Parties'
discussions, for the period of the supply problem, except that [*] for the
PRODUCT during the applicable period, and provided further that if [*] such
PRODUCT at any time during the period, [*] any amounts of such PRODUCT [*] under
this subsection (c)(i) shall immediately terminate;

                  (ii) At such time as Aradigm, according to [*] under
subsection (b) above, is able to meet all of SB's forecasted orders for the
PRODUCTS, and provided that Aradigm at that time [*] the Back-Up License granted
under this Section 6.6(c) shall no longer be exerciseable with respect to such
PRODUCT, and SB shall immediately cease to exercise and practice the Back-Up
License, provided that SB shall retain all rights under this Section 6.6 with
respect to any subsequent supply problem as to any PRODUCT.

                  (iii) If the Back-Up License is due to a supply problem caused
by an event of force majeure (as defined in Section 15.7) affecting Aradigm or
one of its suppliers of components for the affected PRODUCT, then SB's payment
obligations set forth in Section 7.3 with respect to the affected PRODUCT that
is the subject of such Back-Up License [*] manufactured under the Back-Up
License and sold by SB or its AFFILIATES or sublicensees. For any supply problem
that is not caused by an event of force majeure, SB's payment obligations set
forth in Section 7.3 [*] manufactured under the Back-Up License and sold by SB
or its AFFILIATES or sublicensees. Nothing in the foregoing shall limit or
affect in any way SB's obligations to make the payments outlined in Sections 7.2
and 7.3 to the full extent required on all PRODUCTS supplied to SB by Aradigm.

      6.7 PRODUCT SAMPLES. The Parties agree that a program of providing samples
of AERx DEVICES, DRUG PRODUCTS and ACCESSORIES to doctors, hospitals and other
potential customers at no charge will be important to the successful marketing
and commercialization of the AERx SYSTEMS. The COMMERCIALIZATION COMMITTEE shall
discuss and establish a reasonable program for providing such samples to
appropriate entities, provided that Aradigm shall have the right to approve such
sampling rate with respect to any particular PRODUCT, which approval shall not
be unreasonably withheld or delayed. 

* Certain information on this page has been omitted and filed
  separately with the Commission. Confidential treatment has
  been requested with respect to the omitted portions.

Aradigm agrees that [*] to be used by SB in providing such samples, provided
that the numbers of such samples, with respect to any such PRODUCT, do not
exceed the agreed amounts for sampling for the applicable period, unless the
Parties otherwise agree. SB covenants that SB and its AFFILIATES shall not
resell any PRODUCTS [*] for sampling purposes. The COMMERCIALIZATION COMMITTEE
will establish a reasonable means for identifying the PRODUCTS that are [*] SB
shall include in the forecasts delivered under Section 6.5 the number of
PRODUCTS to be ordered for sampling purposes.

      6.8 DELIVERY AND RISK OF LOSS. Delivery of PRODUCTS ordered hereunder
shall be FCA (i.e., "free carrier") at the Aradigm manufacturing site for the
PRODUCT. "FCA" shall be construed in accordance with INCOTERMS 1990 of the
International Chamber of Commerce, except as otherwise provided herein. Title to
and risk of loss of the PRODUCTS purchased hereunder shall transfer to SB upon
delivery to the carrier designated by SB (or if no carrier is designated, the
carrier selected by Aradigm) at that delivery site. PRODUCTS shall be in
FINISHED FORM at delivery, packaged by Aradigm for shipment in an appropriate
manner to be agreed upon by the Parties. At SB's request and cost, Aradigm shall
arrange shipping and/or insurance to specified SB locations, provided that SB
shall be responsible for obtaining all customs clearances required. All costs of
shipping and insurance shall be borne by SB. SB shall be responsible for
compliance with all exportation and importation laws, regulations and duties. To
the extent required by law or regulation, Aradigm agrees to obtain any necessary
export licenses for the export of the PRODUCTS to destinations outside the
U.S.A., and SB shall reimburse Aradigm for all reasonable costs and expenses of
obtaining such export licenses.

      6.9   QUALITY OF MANUFACTURING.

            (a) Aradigm shall manufacture or have manufactured and supply
PRODUCTS in accordance with the SPECIFICATIONS and with cGMP regulations and in
compliance with all applicable laws. Aradigm shall provide a Certificate of
Analysis and Conformance ("COA") to SB with each shipment of PRODUCTS ordered by
SB specifying that such PRODUCTS conform with the SPECIFICATIONS. Aradigm shall
provide the results of the QC analysis conducted by Aradigm along with any
supporting data. SB shall be under no obligation to accept any shipment of
PRODUCTS without an accompanying COA.

            (b) As used in this subsection (b), the term "Remaining Shelf Life"
shall mean, with respect to particular DRUG PRODUCT ordered by SB, the amount of
time remaining from the date that such DRUG PRODUCTS are delivered to SB until
the expiration date of such DRUG PRODUCTS, which expiration date shall be 
consistent with the expiration dating approved by the FDA or other relevant
regulatory authority. At least [six (6)] months prior to commencement of
shipment of DRUG PRODUCTS to SB for commercial sale, the DEVELOPMENT COMMITTEE
shall establish the minimum amount of Remaining Shelf Life (the "Minimum Shelf
Life") that must, on the date of delivery to SB under Section 6.8, remain with
respect to DRUG PRODUCTS delivered to SB. Over the term of the Agreement, the
DEVELOPMENT COMMITTEE may adjust the agreed Minimum Shelf Life period as
appropriate. SB shall be under no obligation to accept any shipment of such
DRUG

                                       36.
<PAGE>   42
PRODUCTS that do not have at least the Minimum Shelf Life remaining on the date
of delivery. If SB elects to accept DRUG PRODUCTS which upon receipt from
Aradigm have less than the Minimum Shelf Life remaining, then SB may return any
such accepted DRUG PRODUCTS that expire while housed in SB's inventory or that
are returned by a customer for credit due to such expiration, and SB shall
receive a full credit for the purchase price that SB paid for such returned DRUG
PRODUCTS against future payments owed by SB to Aradigm under this Agreement.

            (c) Aradigm shall be responsible for the safe handling, storage and
transportation of AERx DEVICES and DRUG PRODUCTS until delivery to SB as
provided in Section 6.8. All PRODUCTS sold and shipped pursuant to this
Agreement shall be manufactured in accordance with all applicable federal, state
and local environmental, health and safety laws and regulations in effect at the
time and place of manufacture of PRODUCTS, and all waste, including but not
limited to all hazardous waste, generated at the time of manufacture of PRODUCTS
shall be disposed of in accordance with all applicable federal, state and local
laws and regulations.

      6.10 ACCEPTANCE. SB shall have the right to test at its expense, using
acceptance testing procedures to be agreed upon by the DEVELOPMENT COMMITTEE, a
portion of each shipment of PRODUCTS to confirm that such shipment meets the
SPECIFICATIONS. Where it is required by the local regulations, further testing
on importation in accordance with the SPECIFICATIONS shall be carried out by SB.
If SB rejects in whole or in part any nonconforming shipment of AERx DEVICES or
DRUG PRODUCTS, SB shall immediately provide Aradigm written notice of such
rejection. Aradigm shall use commercially reasonable efforts to replace the
nonconforming AERx DEVICES or DRUG PRODUCTS, at no additional cost to SB, as
soon as possible; provided, however, that if Aradigm reasonably disputes SB's
conclusion that such AERx DEVICES or DRUG PRODUCTS do not meet the applicable
SPECIFICATIONS, Aradigm shall not be obligated, in order to meet the foregoing
obligation to provide replacement product, to supply more than such amounts of
such products as are available in Aradigm's inventory and shall not be obligated
to maintain such inventory during such dispute, provided that the foregoing
shall not be interpreted to change in any way Aradigm's ongoing supply
obligations with respect to other PRODUCTS ordered by SB in conformance with the
Supply Procedures as provided in Section 6.5. If Aradigm disagrees with SB's
determination that the rejected shipment did not meet the SPECIFICATIONS, a
sample of the rejected shipment shall be submitted to an independent, qualified
third-party laboratory that is mutually acceptable and selected by the parties
promptly in good faith. Such laboratory shall determine whether the rejected
AERx DEVICES or DRUG PRODUCTS (as applicable) meet the SPECIFICATIONS, and such
laboratory's determination shall be final and determinative for purposes of this
Agreement. The Party against whom the laboratory rules shall bear all costs of
the laboratory testing. If the laboratory rules that the shipment failed to meet
SPECIFICATIONS, the replacement shipment shall be at no charge to SB (provided
SB paid for the initial shipment). If the laboratory rules the rejected shipment
met the SPECIFICATIONS, then SB shall accept such batch for use and shall
reimburse Aradigm for the replacement shipment (including all costs of shipping
and insurance). Shipments of AERx DEVICES or DRUG PRODUCTS not meeting the
SPECIFICATIONS may, at Aradigm's option and expense, be returned to Aradigm or
destroyed by SB.

the Agreement for the purchase and sale of the INITIAL PRODUCTS, SB shall pay
to Aradigm [*] of the NET SALES of all INITIAL PRODUCTS sold by SB, its
AFFILIATES or sublicensees where Aradigm owes [*] the above-stated royalty based
on such sales The amounts owing with respect to such sales made in a particular
calendar quarter are due and payable by SB within forty-five (45) days after the
end of such quarter.

      7.4   TIMING OF PAYMENTS.

            (a) The payment obligations under Section 7.3 shall accrue upon the
sale of the particular PRODUCT to the THIRD PARTY purchaser by SB, its AFFILIATE
or sublicensee, which is deemed to occur on the date of the invoice for such
sale. Such payment obligations that have accrued during a particular calendar
quarter shall be payable within forty-five (45) days of the end of such calendar
quarter. Such payments shall be accompanied by a report as provided in Section
5.6.

            (b) The  [*] shall be payable within forty-five (45) days after the

on a country-by-country basis and a PRODUCT-by-PRODUCT basis.

            (d) All amounts due under this Agreement shall be payable in U.S.
Dollars. If governmental regulations in a particular foreign country prevent
remittances of such amounts to Aradigm in the U.S.A. with respect to sales of
PRODUCTS made in that country, SB shall pay the amounts due based on sales in
that country into a bank account in such country designated by Aradigm, which
amounts may be in the local currency. Aradigm shall have the reciprocal right
with respect to any amounts that are due to SB under Section 3.3.

      7.5 WITHHOLDING TAXES. SB agrees to use good faith, DILIGENT EFFORTS to
eliminate (or, if that is not possible, to minimize) any withholding or other
taxes assessed by any foreign country on the amounts paid by SB to Aradigm

income). In the event that a tax is assessed on Aradigm by a foreign country on
account of the amounts payable to Aradigm under Section 7.3 of this Agreement

with respect to any withholding taxes assessed on royalties which are due to SB
under Section 3.3.

      7.6 COMPULSORY LICENSES. In the event that a governmental agency in any
country grants to a THIRD PARTY, or compels Aradigm to grant to a THIRD PARTY, a
license under the ARADIGM PATENTS which license permits such THIRD PARTY to
make, use and sell in such country any AERx SYSTEM, AERx DEVICE, DRUG PRODUCT or
ACCESSORY, then [*] such THIRD PARTY with respect to SB's use and sale of such
PRODUCT in such country to the [*] of this Agreement; but provided that if the
foregoing would result in [*] then at Aradigm's request senior management
officers of the Parties shall meet and discuss in good faith an appropriate
resolution to the problem.

      7.7 CONVERSION OF NET SALES. NET SALES in a particular country outside the
U.S.A. during a particular calendar quarter shall be equal to the year-to-date
NET SALES converted into U.S.A. Dollars less year-to-date NET SALES for the
previous calendar quarter(s) converted into U.S.A. Dollars. NET SALES shall be
converted from the currency of the sale into U.S.A. Dollars at the average daily
rates of exchange for the year from January 1 to the end of such calendar
quarter, from such country's currency into U.S.A. Dollars as reported in the
Wall Street Journal or some other source agreeable to both Parties, and shall be
converted at such average year-to-date rate at the end of such quarter. Aradigm
shall use the same mechanism for converting net sales with respect to royalties
which are due to SB under Section 3.3.

      7.8 AUDIT RIGHTS. SB shall keep and require its AFFILIATES and
sublicensees to keep complete and accurate records of all NET SALES and Third
Party Product Royalties and Third Party Device Royalties paid by SB, and SB
shall obtain and keep copies of such records sent by its AFFILIATES and
sublicensees. Upon twenty (20) days prior written notice to SB, Aradigm shall
have the right, at Aradigm's expense, to have a certified public accountant or
the equivalent reasonably acceptable to SB audit such records kept by SB to
confirm that all payments made hereunder are accurate and that the Third Party
Product Royalties and Third Party Device Royalties submitted by SB are accurate.
Any audit performed pursuant to this Section shall take place during the life of
this Agreement and for six (6) months after its termination or expiration;
provided, however, that such examination shall not take place more often than
once a year and shall not cover such records for more than the preceding two (2)
calendar years. In addition, any such audit shall take place during regular
business hours at SB's principal place of business or at any other location
where SB may make the applicable records available; provided, however that
access to such records shall be provided in such manner so as not to interfere
with the normal conduct of SB's business or operations. Access to such records
kept by SB shall be limited to such records (or the relevant portion thereof) as
are reasonably required to determine that payments made under this Agreement are
accurate (or if such payments are not accurate then to determine the proper
payment amount), and provided further that such accountant shall report to
Aradigm only as to the accuracy of the payments and Aradigm and/or its
accountant shall execute such confidentiality agreements with respect to such
access as SB may request. Any amounts showed to be owed to Aradigm shall be
immediately

paid with interest at [ * ] per month (or the maximum amount allowed by law, if
less) from the day such amounts were first due until paid. In addition, if the
audit shows underpayment by [ * ] or more of the amounts due during the audited
period, SB shall pay Aradigm's reasonable expenses in having such audit
conducted. SB shall have a reciprocal right to audit Aradigm's records, under
similar provisions, including the right of collection of interest for any
overpayment by SB to Aradigm hereunder, and right to have its reasonable
expenses in conducting such audit paid by Aradigm if the audit shows overpayment
by [ * ] or more of the amounts paid by SB during the audited period, to
determine if the DEVELOPMENT COSTS, MANUFACTURING COSTS, and Third Party Product
Royalties and Third Party Device Royalties submitted by Aradigm hereunder are
accurate. Aradigm shall have the reciprocal obligation to keep complete and
accurate records of DEVELOPMENT COSTS, MANUFACTURING COSTS, Third Party Product
Royalties, Third Party Device Royalties and net sales which are subject to the
royalty payments owed to SB by Aradigm under Section 3.3, and SB shall have a
reciprocal right to audit Aradigm's records with respect to royalty payments
owed to SB by Aradigm under Section 3.3 to determine if the payments submitted
to SB are accurate, under similar provisions, including the right of collection
of interest for any underpayment by Aradigm to SB hereunder, and right to have
its reasonable expenses in conducting such audit paid by Aradigm if the audit
shows underpayment by [ * ] or more of the amounts paid by SB during the audited
period.

8.    WARRANTY AND PRODUCT SERVICE.

      8.1 WARRANTY.

            (a) AERx DEVICE; ACCESSORIES. Aradigm warrants to SB, which warranty
SB may extend to all purchasers and end-users, at the time of any sale that, for
a period of [ * ] from the date of delivery to an end-user of an AERx DEVICE
or ACCESSORY, such AERx DEVICE or ACCESSORY shall conform in all material
respects to the SPECIFICATIONS, shall conform to any SPECIFICATIONS required by
the applicable REGULATORY APPROVALS, and shall be free from material defects in
materials and workmanship. The obligations of Aradigm with respect to breach of
the foregoing warranty are expressly limited to, at Aradigm's option, the repair
or replacement of the AERx DEVICE or ACCESSORY that fails to meet the warranty,
at Aradigm's cost. Aradigm's obligations hereunder apply with respect to a
particular AERx DEVICE or ACCESSORY only if such PRODUCT actually fails to meet
the above warranty and such failure was not caused by misuse, attempts to
repair, or by accident, fire or other hazard unless caused by Aradigm, its
AFFILIATES or their respective officers, directors, representatives, agents or
employees. For clarification, the foregoing limitation shall not be interpreted
to limit any rights under Section 12.1.

            (b) DRUG PRODUCT. Aradigm warrants that DRUG PRODUCT delivered
hereunder will (i) be manufactured by Aradigm in accordance with cGMP and other
applicable FDA and other rules and regulations of the U.S.A. and MAJOR MARKET
COUNTRIES and (ii) conform to the SPECIFICATIONS at the time of delivery. SB's
exclusive remedies and Aradigm's entire liability with respect to the warranty
in this Section 8.1(b) are as set forth in 

* Certain information on this page has been omitted and filed separately with

                                       46.
<PAGE>   52

Section 6.10 with respect to acceptance of PRODUCTS, provided that the foregoing
does not limit any rights under Section 12.1.

      8.2 DISCLAIMER. EXCEPT FOR THE EXPRESS WARRANTIES AND REPRESENTATIONS
CONTAINED IN THIS AGREEMENT, NEITHER SB NOR ARADIGM MAKES, AND EACH HEREBY
EXPRESSLY DISCLAIMS, ANY WARRANTIES OR REPRESENTATIONS, EITHER EXPRESS OR
IMPLIED, WHETHER IN FACT OR IN LAW, INCLUDING WITHOUT LIMITATION IMPLIED
WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE OR
NON-INFRINGEMENT.

      8.3 PRODUCT HELP-LINE. SB understands and agrees that SB shall be
responsible for providing first-line help-line service to purchasers or users of
the PRODUCTS, which means addressing and resolving all questions relating to use
or functionality of the PRODUCTS posed by end users of the PRODUCTS, to the
extent that SB's designated service personnel are capable. SB shall provide
help-line service to the end users of the PRODUCTS and shall provide adequate
training to the personnel staffing such help-line. With respect to any such
questions regarding the PRODUCTS that SB's designated service personnel are
unable to resolve after reasonable efforts, SB will refer such customers to
Aradigm for second-line customer support service hereunder to obtain resolution
of such questions. SB shall make all such requests for second-line customer
service by telephone or such other means of communication (such as e-mail) as
Aradigm may implement from time to time. Such second-line customer service shall
be available during such hours as Aradigm establishes.

      8.4 PRODUCT SERVICE. Aradigm agrees to establish a service center for
receiving from end users any AERx DEVICES and ACCESSORIES that have experienced
malfunctions, in order to perform or arrange for service to correct such
malfunctions. Aradigm agrees to use DILIGENT EFFORTS to repair or replace
malfunctioning units promptly after receipt using mutually agreed upon criteria
to determine whether the unit is to be repaired or replaced. For any such
malfunctioning units that are covered by the warranty under Section 8.1, such
repair or replacement cost shall be at Aradigm's expense. Prior to launch of the
first PRODUCT, the Parties will agree to a policy regarding payment to Aradigm
for the costs of product service for units no longer covered by the warranty
provided in Section 8.1.

9.    INTELLECTUAL PROPERTY.

      9.1 OWNERSHIP OF TECHNOLOGY. Aradigm shall retain all right, title and
interest in and to the ARADIGM PATENTS and all INFORMATION owned or CONTROLLED
by Aradigm, and SB shall retain all right, title and interest in and to the SB
PATENTS and all INFORMATION owned or CONTROLLED by SB, subject to the rights
granted hereunder. Each Party shall have and retain sole and exclusive title to
all INVENTIONS that are made, conceived, reduced to practice or generated solely
by its or its AFFILIATE'S employees, agents, or other persons acting under its
authority, and to all PATENTS claiming such INVENTIONS. Each Party shall own a
fifty percent (50%) undivided interest in all JOINT INVENTIONS made, conceived,
reduced to practice or generated under the Agreement, and all JOINT PATENTS


                                       47.
<PAGE>   53

claiming such JOINT INVENTIONS. Except as expressly provided otherwise in this
Agreement, each joint owner may make, use, sell, keep, license, assign, or
mortgage such JOINT INVENTIONS and JOINT PATENTS, and otherwise undertake all
activities a sole owner might undertake with respect to the same, without the
consent of and without accounting to the other joint owner. Inventorship of
inventions shall be determined under U.S. patent law regarding inventorship.

      9.2 PROSECUTION AND MAINTENANCE OF PATENTS; ABANDONMENT. Each Party shall
have the sole right and responsibility to file, prosecute and maintain its
independently owned PATENTS and shall bear all expenses associated therewith.
Aradigm shall use DILIGENT EFFORTS to file, prosecute and maintain the ARADIGM
PATENTS (or foreign equivalents thereof) in the countries listed in Exhibit F
(to the extent such prosecution is permitted under the applicable patent laws).
The Parties agree to discuss in good faith a mutually agreeable patent strategy
with respect to all JOINT INVENTIONS that may be patentable. With respect to all
JOINT INVENTIONS for which the Parties agree patent protection should be sought,
SB and Aradigm shall cooperate in good faith to file, prosecute and maintain the
JOINT PATENTS covering such JOINT INVENTIONS, and the Parties shall jointly bear
all expenses associated therewith. However, either Party may choose at any time
not to continue to pay any such prosecution and maintenance costs with respect
to a particular JOINT PATENT, and shall immediately thereafter assign all its
rights in such JOINT PATENT claiming a JOINT INVENTION to the Party that pays
all such costs. In the event that a Party elects not to prosecute a PATENT
application on a particular JOINT INVENTION, the other Party may do so at its
sole discretion and expense, and all rights in such JOINT INVENTION and the
JOINT PATENT claiming such invention shall be assigned to such other Party.
Aradigm shall have the right, but not the obligation, to seek extensions of the
terms of ARADIGM PATENTS and to seek to obtain Supplemental Protection
Certificates, and similar rights, based on ARADIGM PATENTS at its own expense.
Aradigm shall reasonably consider SB's requests with respect to such efforts
relating to the FIELD. At Aradigm's request, SB shall provide to Aradigm a copy
of any requested REGULATORY APPROVAL held by SB, and any information relating
thereto, to the extent necessary for the purpose of seeking such extensions of
ARADIGM PATENTS and/or obtaining such Supplemental Protection Certificates or
similar rights. If Aradigm decides to abandon prosecution or maintenance of a
particular ARADIGM PATENT whose claims relate directly to an AERx SYSTEM, AERx
DEVICE, ACCESSORY or DRUG PRODUCT, SB may request that SB have the right to
continue such prosecution and/or maintenance, which request Aradigm will
reasonably consider, provided that Aradigm need not in any event grant any such
request if Aradigm has a strategic reason, with respect to its prosecution
strategy for its PATENTS, for abandoning such PATENT (which reason may not
include simply cost savings). If Aradigm grants SB's request, SB may continue
the prosecution and maintenance of such ARADIGM PATENT, at SB's expense,
provided that SB keep Aradigm reasonably informed of the progress of any such
prosecution.

      9.3 THIRD PARTY TECHNOLOGY. The Parties hereby agree that if either Party
becomes aware of any technology or intellectual property rights owned by a THIRD
PARTY which may be useful or necessary to the DEVELOPMENT, manufacture, use, or
sale of a particular PRODUCT or PRODUCTS, such Party shall bring such
information to the attention of the 


                                       48.
<PAGE>   54
DEVELOPMENT COMMITTEE. The DEVELOPMENT COMMITTEE shall discuss and analyze the
information and situation, to determine whether to seek to acquire or obtain a
license to such technology or intellectual property rights. However, except as
otherwise provided in this Section and in Sections 9.5 or 9.6, neither the
DEVELOPMENT COMMITTEE nor any Party shall obtain or license such technology or
intellectual property rights for use under this Agreement without the [ * ] if
such acquisition or license would require payment of any amounts to the THIRD
PARTY owner with respect to the DEVELOPMENT, manufacture, use or sale of
PRODUCTS hereunder, which [ * ] shall include [ * ] such acquisition or license
shall be [ * ]. With respect to a proprietary ANALGESIC DRUG owned by a THIRD
PARTY, neither Party may license such ANALGESIC DRUG for use in a DRUG PRODUCT
hereunder without the written approval of both Parties, which approval shall [*]
of royalty or other payments owed to such THIRD PARTY for such license. For
clarity, nothing in the foregoing shall prevent a Party from obtaining or
licensing THIRD PARTY technology if such Party is entirely responsible for all
payments relating to such acquisition or licensing.

      9.4 INTELLECTUAL PROPERTY ISSUES. In the event that either Party
reasonably believes that the manufacture or sale of a particular PRODUCT may
infringe a PATENT owned by a THIRD PARTY (whether before or after an action
based on such PATENT has been filed), then such Party will provide the other
Party all INFORMATION in its possession relating to such belief. Promptly
thereafter, the Parties shall meet to discuss in good faith the appropriate
steps to take to address such possible infringement, which may include, without
limitation: (a) negotiating and entering into a license agreement with such
THIRD PARTY that grants the Parties the right to continue making, using and
selling such PRODUCT, or (b) modifying the applicable PRODUCT so that the
Parties believe it no longer infringes, or (c) proceeding without any change
based on a reasonable analysis that such PRODUCT does not infringe and/or such
PATENT is not valid or enforceable. In the event that the Parties decide to
obtain a license from such THIRD PARTY, the consideration for such license shall
be paid as provided in Section 9.7 below. In the event one Party [ * ] during
the exercise of SB's rights under this AGREEMENT, but [ * ] the Parties shall
submit such issue promptly thereafter to an independent, mutually-acceptable,
THIRD PARTY patent attorney, who shall [ * ]. The expenses of engaging such
patent attorney for such [ * ]. If such attorney determines that [ * ] as
provided in Section 9.7. For clarity, nothing in the foregoing shall prevent a
Party from obtaining or licensing THIRD PARTY technology if such Party is
entirely responsible for all payments relating to such acquisition or licensing.

      9.5 DEFENSE AND SETTLEMENT OF THIRD PARTY PATENT CLAIMS. PATENT
infringement claims by THIRD PARTIES against PRODUCTS shall be addressed as
follows:

  the Commission. Confidential treatment has been requested with respect to the
  omitted portions.

                                       49.
<PAGE>   55
 (a) If a THIRD PARTY brings any claim or action (a "3d Party Patent Action")
against SB or Aradigm that the manufacture, use, sale, offer for sale, or
importation of a PRODUCT infringes an issued PATENT that is owned or controlled
by such THIRD PARTY (but excluding from the definition of "3d Party Patent
Action" any claims or actions that the ANALGESIC DRUG in a PRODUCT is
infringing, which is provided for in Section 9.6 below), the Party subject to
such 3d Party Patent Action shall have the right to defend itself, at its
expense and using counsel of its choosing. Each Party agrees to notify the other
promptly in writing of any such 3d Party Patent Action against it. The Parties
agree to cooperate reasonably in the defense of 3d Party Patent Actions,
provided that each Party shall have the sole final discretion with respect to
its own defense, [ * ]. In the event that SB is subject to any 3d Party Patent
Action but Aradigm is not also subject to such 3d Party Patent Action, SB agrees
that Aradigm shall be permitted to join such 3d Party Patent Action to defend,
at its own expense, its interests in such action as a necessary party, whether
by interpleader or otherwise. SB agrees that SB will not object to any attempt
by Aradigm to become a party to any such dispute.

            (b) In any 3d Party Patent Action against SB, SB shall have the
right to settle or compromise at SB's expense such 3d Party Patent Action
without Aradigm's prior written consent, provided that, subject to subsection
(c) below, in any such settlement or compromise (i) [*] by the manufacture, use,
sale, offer for sale, or importation of the accused PRODUCTS, (ii) [ * ], (iii)
if SB obtains a license from the THIRD PARTY under the applicable PATENTS to
continue to use, import, market, offer for sale or sell the PRODUCT, such
license [ * ] and (iv) Aradigm's [ * ]. In any 3d Party Patent Action against
Aradigm, Aradigm shall have the right to settle or compromise at Aradigm's
expense such 3d Party Patent Action without SB's prior written consent, provided
that, subject to subsection (c) below, in any such settlement or compromise (i)
if Aradigm obtains a license from the THIRD PARTY under the applicable PATENTS
to manufacture, supply and sell to SB the PRODUCT, such license [ * ] and (ii)
SB's right [ * ] Aradigm shall not settle or compromise such claim or action [ *
] if such settlement or compromise would [ * ] under this Agreement.

            (c) In the event that: (1) a Party that is a defendant in a 3d Party
Patent Action [ * ] that is the subject of such 3d Party Patent Action [ * ] or
otherwise that such 3d Party Patent Action should [ * ] and (2) such Party is 
[ * ] the other Party that allows the Parties to continue to make, import, use,
offer for sale and sell the accused PRODUCT as contemplated hereunder; then upon
notice to the other Party, the appropriate

senior management officers of each Party shall immediately meet to discuss in
good faith and agree upon [*] to such 3d Party Patent Action, which may include,
without limitation: (i) modifying the applicable PRODUCT so that it no longer
infringes, or (ii) ceasing to manufacture and sell such PRODUCT and proceeding
promptly to develop a replacement PRODUCT therefor on terms commercially
acceptable to each Party. During such discussions [*] If the Parties do not
agree, within [*] days of the notice provided under this subsection (c)
with respect to such 3d Party Patent Action, on a resolution to the situation,
then such situation shall immediately be referred to binding arbitration under
Section 13.1 for resolution, with the following additional requirements for such
arbitration: The object of such arbitration shall be that the arbitration
establish an appropriate resolution to such 3d Party Patent Action with respect
to the affected PRODUCT, which resolution shall [*] If such arbitration is
required hereunder, the Parties hereby agree that immediately upon such referral
to arbitration, the Parties will agree on an arbitration procedure and mechanism
that assures achieving a decision under the arbitration on an expedited basis,
it being agreed that a resolution of the issue as soon as possible is critical
to the defendant in the underlying 3d Party Patent Action.

            (d) Notwithstanding the foregoing, [*] in defending against any
claim or action under Section 9.5(a) to the extent such claim is based upon any
[*] or its AFFILIATE or a THIRD PARTY acting on behalf of [*] or its AFFILIATE
or a THIRD PARTY acting on behalf of [*] of the PRODUCT in combination with any
product or service not [*].

            (e) Any royalty obligation that Aradigm or SB is obligated to pay
under a final judgment for future sales of the PRODUCT shall be [*] pursuant to
the provisions of Section 9.7 below.

      9.6 THIRD PARTY CLAIMS REGARDING ANALGESIC DRUG. SB shall defend any claim
or action by a THIRD PARTY against SB and/or Aradigm based on a claim that the
ANALGESIC DRUG in a PRODUCT infringes a PATENT issued in the U.S.A. or a MAJOR
MARKET COUNTRY which is owned or controlled by such THIRD PARTY, provided that
Aradigm notifies SB promptly in writing of such action against Aradigm. Aradigm
shall give SB control of the defense thereof (and any negotiations for
settlement or compromise thereof) and will cooperate fully in the defense
thereof, provided that Aradigm shall have the right to participate in all
aspects of such defense relating to claims against Aradigm and to consult with
SB thereupon, and SB shall reasonably consider all Aradigm's suggestions
regarding defense of the claims against Aradigm. Subject to SB having such
control, Aradigm, at its own expense, may participate in such defense of Aradigm
using counsel of its choice, provided that such participation does not conflict
with SB's defense. SB shall not settle or compromise any such claim or action
without Aradigm's prior written consent, if such settlement or compromise would

<PAGE>   57

impose on Aradigm any obligation to pay or incur any costs or expenses. [*] to
the extent that such defense relates to claims against the ANALGESIC DRUG per
se. In the event that SB does not undertake the defense of an action against
ARADIGM hereunder within fifteen (15) days of notice to SB of such claim, then
ARADIGM shall have the full right to defend itself, using counsel of its own
choosing, against such claim, including any negotiations for settlement or
compromise thereof, and SB shall reimburse ARADIGM for all reasonable costs and
expenses of such defense.

      9.7 PAYMENT FOR THIRD PARTY LICENSES. If the Parties agree to obtain a
license under THIRD PARTY PATENTS with respect to manufacture, use or sale of a
PRODUCT, as provided in Section 9.4 or if the Parties are required to pay
royalties to a THIRD PARTY to settle or otherwise resolve a PATENT infringement
suit alleging PATENT infringement by a PRODUCT, as provided in Section 9.5, the
Parties agree that all such royalties shall be paid as provided in this Section.
For royalties that are based on the manufacture, use, sale, offer for sale or
importation of DRUG PRODUCTS or the use of an AERx SYSTEM (the "Third Party
Product Royalties"), the payment shall be as provided in subsection (a) below.
For royalties that are based on the manufacture, use, sale, offer for sale or
importation of an AERx DEVICE or ACCESSORY (the "Third Party Device Royalties"),
the payment shall be as provided in subsection (b) below.

Section 6.9(b)), applicable to the particular AERx DEVICES or ACCESSORIES on
which such Third Party Device Royalties are (or would be) owed, to be less than
[*]. Any amounts of such Third Party Device Royalties that [*] limitation shall

the NET SALES of such AERx DEVICE or ACCESSORIES, then Aradigm shall give SB
written notice, and the Parties shall meet to address such situation by good
faith negotiation between senior management representatives of the Parties using
DILIGENT EFFORTS, to be commenced promptly, to seek to find [*]. In the event
that such management representatives cannot reach such agreeable resolution to

matter shall be resolved by binding arbitration under Section 13.1, with the
following additional requirement for such arbitration: The object of such
arbitration shall be that the arbitration establish a [*] such Third Party

to Section 9.3 or 9.4, under a PATENT claiming an ANALGESIC DRUG composition of

agree on the [*] entry into such license.

      9.8   ENFORCEMENT OF ARADIGM PATENT RIGHTS.

            (a) If any ARADIGM PATENT is infringed by a THIRD PARTY in any
country, the Party to this Agreement first having knowledge of such infringement
shall promptly notify the other in writing. The notice shall set forth the facts
of that infringement in reasonable detail. Aradigm shall have the primary right,
but not the obligation, to institute, prosecute, and control any action or
proceeding with respect to such infringement, by counsel of its own choice and
at its expense.

            (b) If such suspected infringement involves the manufacture, use,
sale, or offer for sale in the TERRITORY of an AERx SYSTEM, AERx DEVICE, DRUG
PRODUCT or ACCESSORY that is intended for use in the FIELD, and the alleged
infringement is of an ARADIGM PATENT whose claims are primarily directed towards
the FIELD or products for use in the FIELD (a "Field Infringement"), SB shall
have the right, at its own expense, to be represented in any such action by
counsel of its own choice, provided that Aradigm shall control the action.
Further, if SB reasonably believes that a THIRD PARTY is infringing an ARADIGM
PATENT in a manner constituting a Field Infringement, and Aradigm fails to bring
an action or proceeding against such suspected infringer within a period of [*]
days after having knowledge of such Field Infringement, then, and only then, 
SB shall have the right to bring and control an action against such infringer 
by counsel of its own choice and at its expense, and Aradigm shall have the 
right to be represented in any such action by counsel of its own choice at 
its own expense. The Party controlling any such action involving a Field 
Infringement shall

consider in good faith the interests of the other Party in so doing, and in any
event shall not settle or consent to an adverse judgment in any such action that
would have a material adverse effect on the rights or interests of the other
Party without the prior express written consent of the other Party. If one Party
brings any such action or proceeding, the other Party agrees to be joined as a
Party plaintiff if necessary to prosecute the action and to give the first Party
reasonable assistance and authority to file and prosecute the suit

            (c) Any damages or other monetary awards recovered in an action
against an infringer of a ARADIGM PATENT based on a Field Infringement shall be
allocated to the Parties in the following manner: first, to reimburse Aradigm
and SB for their respective out-of-pocket expenses (including reasonable
attorneys' fees and costs) incurred in prosecuting such infringement action (if
the recovery is less than both Party's costs, then on a pro rata basis based
upon their respective out-of-pocket expenses); and second, [*] of the remaining
balance from such recovery shall be allocated to the Party bringing suit, and
the remaining [*] of such balance shall be allocated as follows: [*], and such
amount shall be paid to [*]. Aradigm retains all other rights with respect to
enforcement of ARADIGM PATENTS.

            (d) In the event a counterclaim is asserted against SB or Aradigm
during an action prosecuted under this Section 9.8, which counterclaim is not
otherwise addressed elsewhere in the Agreement, SB or Aradigm, as applicable,
shall have the rights to defend against such counterclaim according to the
procedures outlined in Sections 9.5(a), (b) and (c).

      9.9 ENFORCEMENT OF JOINT PATENT RIGHTS. If any JOINT PATENT is infringed
by a THIRD PARTY in any country in the TERRITORY, the Party to this Agreement
first having knowledge of such infringement shall promptly notify the other in
writing. The notice shall set forth the facts of that infringement in reasonable
detail. Aradigm shall have the primary right, but not the obligation, to
institute, prosecute, and control any action or proceeding with respect to such
infringement, by counsel of its own choice, and SB shall have the right, at its
own expense, to be represented in any such action by counsel of its own choice.
If Aradigm fails to bring an action or proceeding against such suspected
infringer within a period of ninety (90) days after having knowledge of such
infringement, then SB shall have the right to bring and control an action
against such infringer by counsel of its own choice, and Aradigm shall have the
right to be represented in any such action by counsel of its own choice at its
own expense. The Party controlling any such action shall consider in good faith
the interests of the other Party in so doing, and shall not settle or consent to
an adverse judgment in any such action which would have a material adverse
effect on the rights or interests of the other Party without the prior express
written consent of the other Party, which consent shall not be unreasonably
withheld. If one Party brings any such action or proceeding with respect to a
JOINT PATENT, the other Party agrees to be joined as a Party plaintiff if
necessary to prosecute the action and to give the first Party reasonable
assistance and authority to file and prosecute the suit. Any damages or other
monetary awards recovered in an action against an infringer of a JOINT PATENT
shall be allocated to the Parties in the following manner: first, to the
reimbursement of Aradigm and SB

for their respective out-of-pocket expenses (including reasonable attorneys'
fees and costs) incurred in prosecuting such infringement action (if the
recovery is less than both Party's costs, then on a pro rata basis based upon
their respective out-of-pocket expenses; and second [*] of the remaining
balance from such recovery shall be allocated to the Party bringing suit, and
the remaining [*] of such balance shall be allocated as follows: [*] and such
amount shall be paid to [*].

      9.10 TRADEMARKS AND TRADENAMES GENERALLY. The DEVELOPMENT COMMITTEE will
select, after consultation and mutual agreement, trademarks or tradenames to be
owned by Aradigm and used by SB under license for each AERx SYSTEM and other
related PRODUCTS (the "Product Marks"). With respect to the selection of Product
Marks, it is agreed and understood that if a REGULATORY APPROVAL is achieved in
the European Union for an AERx SYSTEM, a single Product Mark may need to be
employed throughout the European Union with respect to such AERx SYSTEM,
depending on the regulations in existence at the time. If the DEVELOPMENT
COMMITTEE agrees, one of the Product Marks to be used on all PRODUCTS is
AERx(TM) Pain Management System; if such mark is not agreed to, then Aradigm may
specify an alternative mark to be used on all PRODUCTS, subject to SB's approval
to be withheld only if there is a substantial trademark infringement issue with
the proposed mark, or other issue (such as likelihood of confusion) identified
by SB reasonably and good faith that could interfere with use of such mark. Such
mark designated by Aradigm (whether AERx, if agreed, or the other acceptable
mark) shall be referred to herein as the "APMS Trademark". As provided in
Section 9.11 below, Aradigm agrees that SB shall have the exclusive right to use
the APMS Trademark, which right is solely for use in association with marketing
and sale of the PRODUCTS for use in the FIELD, but such right shall not prevent
Aradigm from using or licensing the AERx(TM) trademark (or such other
generally-applicable mark as selected by Aradigm as provided above) for any use
other than in the FIELD. SB, its AFFILIATES and/or sublicensees shall not adopt,
use, or register any acronym, trademark, tradename, service mark or other
marketing name of Aradigm or any confusingly similar mark or symbol as part of
SB's or its AFFILIATE'S own trademark or tradename for other products it
markets. Likewise, Aradigm, its AFFILIATES and/or sublicensees shall not adopt,
use, or register any acronym, trademark, trade name, service mark or other
marketing name of SB or any confusingly similar mark or symbol as part of
Aradigm's or its AFFILIATE'S own trademark or trade name for other products it
markets. For clarification, it is agreed that SB shall have the unilateral right
to select trademarks for any SB PROPRIETARY DRUG and Aradigm shall have no
ownership interest in such marks.

      9.11 TRADEMARK LICENSE. Subject to the terms of this Agreement, Aradigm
hereby grants to SB a license in the TERRITORY, with the right to grant
sublicenses to SB's permitted sublicensees under Section 5.1, to use the Product
Marks, including the APMS Trademark, for the term of this Agreement in
connection with the marketing, promotion and sale of PRODUCTS for use in the
FIELD as contemplated in this Agreement. Such license shall be exclusive as to
all THIRD PARTIES, but Aradigm shall retain all its rights under such Product
Marks as necessary 


* Certain information on this page has been omitted and filed
  separately with the Commission. Confidential treatment has
  been requested with respect to the omitted portions.


                                       55.
<PAGE>   61

to perform its obligations under this Agreement, and Aradigm shall retain all
its rights to use the AERx(TM) trademarK (or such other generally-applicable
mark as selected by Aradigm as provided in Section 9.10 above) for any use
outside the FIELD. SB's right to use the Product Marks, shall terminate in each
country in which SB's rights under this Agreement to distribute, market and sell
the PRODUCTS are terminated in accordance with this Agreement.

      9.12 TRADEMARK REGISTRATION. With respect to each Product Mark (as defined
in Section 9.10) selected by the Parties under Section 9.10, and for each
country in which SB intends to market a PRODUCT using such Product Mark, the
Parties determine which Party shall be responsible for searching, filing,
registering and maintaining a registration for such Product Mark in such
country. The Parties shall share equally all expenses incurred in obtaining and
maintaining such registrations of Product Marks in the TERRITORY. In case a
particular Product Mark is not available for use and registration in connection
with a PRODUCT for use in the FIELD in a particular country, due to a rejection
of the trademark by a government agency, actual or threatened opposition,
cancellation or litigation as to use and/or registration of the Product Mark by
a THIRD PARTY, and/or a decision by the DEVELOPMENT COMMITTEE that use of the
Product Mark is likely to cause confusion with a THIRD PARTY'S trademark, the
DEVELOPMENT COMMITTEE shall select, and the Parties shall approve, an alternate
mark as the Product Mark for such PRODUCT in such country. In those countries
where a trademark license must be recorded, Aradigm will provide and record a
separate trademark license for the Product Marks at Aradigm's expense.

      9.13 GOODWILL AND USE. The ownership of all goodwill that arises or
accrues from the use of the Product Marks (as defined in Section 9.10) shall
vest in and inure to the benefit of Aradigm. SB shall submit to Aradigm copies
of all packaging, promotional materials, advertising and marketing literature
relating to a PRODUCT that contain any Product Mark for Aradigm's reasonable
approval prior to their first use and thereafter prior to implementing any
change or addition to such previously approved packaging, promotional materials,
advertising and marketing literature. If Aradigm has not responded within four
(4) weeks after any such submission, Aradigm's approval with respect to the
submission will be deemed to have been received.

      9.14 DEFENSE OF TRADEMARK CLAIM. In the event that any THIRD PARTY
initiates any claim, complaint, suit, proceeding or cause of action (a
"Trademark Claim") against Aradigm, SB or any of their respective AFFILIATES,
officers, directors or employees alleging trademark infringement resulting from
the use and/or registration of a Product Mark (as defined in Section 9.10), the
Party first having knowledge of such Trademark Claim shall provide the other
Party immediately with all information relating to such Trademark Claim.
Promptly thereafter, the Parties shall meet and discuss in good faith the
appropriate actions to take in response to such Trademark Claim, provided that,
in any event the Party sued may defend itself against such claim if necessary.
Each Party agrees to cooperate fully with the other Party and its agents in
defense of any such Trademark Claim. [*] officers, directors, employees, agents,
successors and assigns from and against any loss, damage or liability, including
for attorney's fees and costs, that may result from any action brought by a
THIRD PARTY based on SB or its AFFILIATES'

                                       56.

use of the APMS Trademark. All expenses relating to the defense of any Trademark
Claim, any amounts payable to THIRD PARTIES to settle or otherwise resolve such
Trademark Claim with respect to the APMS Trademark, and all costs associated
with recall and replacement of PRODUCTS bearing the APMS Trademark, to the
extent required by an adverse judgment in favor of such THIRD PARTY, [*] by
Aradigm, and such recall shall not be subject to the provisions of Section 6.13.
Neither Party shall settle or otherwise resolve such Trademark Claim in a manner
that adversely affects the other Party's rights in the Product Mark without the
other Party's prior written consent.

      9.15 INFRINGEMENT OF PRODUCT MARK. In the event that Aradigm or SB becomes
aware of actual or threatened infringement by a THIRD PARTY of a Product Mark
(as defined in Section 9.10) anywhere in the TERRITORY, that Party shall
promptly notify the Party in writing of all information relating to such
infringement. SB shall have the first right, but not the obligation, to bring,
at its own expense, an infringement and/or opposition or cancellation action
against the THIRD PARTY infringer and to use Aradigm's name in connection
therewith and to name Aradigm as a party thereto. If SB does not commence a
particular infringement and/or opposition or cancellation action within ninety
(90) days of receipt of the notice of infringement, then Aradigm, after
notifying SB in writing, shall have the right, but not the obligation, to bring
such infringement and/or opposition or cancellation action at its own expense.
The Party conducting such action shall have full control over its conduct,
including settlement thereof, provided, however, that SB shall not settle or
otherwise resolve any such action relating to the APMS Trademark (as defined in
Section 9.10) in a manner that adversely affects Aradigm's rights in the APMS
Trademark without Aradigm's prior written consent. The Parties shall keep each
other informed about the progress and status of all litigation or actions
brought under this Section 9.15, and SB and Aradigm shall reasonably assist one
another and cooperate in any such litigation or action at the other's request
without expense to the requesting Party. Aradigm and SB shall recover first
their respective actual out-of-pocket expenses, or pro rata proportions thereof,
associated with any litigation brought under this Section 9.15, or settlement
thereof, out of any damages, settlement payments or other recovery received by
either Party. Any amounts remaining from such damages, settlement payments or
other recovery shall [*]

      9.16 TRADEMARK LITIGATION INDEMNITY. In any action brought pursuant to
Section 9.15, the Party bringing the action shall indemnify the other Party, its
AFFILIATES, and sublicensees, and their respective officers, directors,
shareholders, employees, agents, successors and assigns from any loss, damage or
liability, including for attorney's fees and costs, that may result from claims,
counterclaims or crossclaims asserted by the defendant in such action, except to
the extent that such losses, damages or liabilities result from negligence or
willful misconduct of the other Party.

10. EXCHANGE OF INFORMATION, CONFIDENTIALITY AND PUBLICATION.

      10.1 EXCHANGE OF INFORMATION. Promptly after the Effective Date, Aradigm
shall disclose and supply to SB all INFORMATION relating to the FIELD, to the
extent known to Aradigm and Aradigm is legally able to disclose, that is
necessary to enable SB to fully carry out

                                       57.
<PAGE>   63

all of its rights and obligations under this Agreement. Thereafter, during the
term of the Agreement, Aradigm shall promptly disclose and supply to SB any
further INFORMATION meeting the foregoing requirements that may have become
known to Aradigm during such time. For clarification, the foregoing obligation
shall not require Aradigm to disclose proprietary INFORMATION relating to
manufacturing of the PRODUCTS except if required as provided in Section 6.6.

      10.2 CONFIDENTIALITY. Except as otherwise provided in this Article 9,
during the term of this Agreement and for a period of [*] thereafter, each Party
shall maintain in confidence and shall use only for purposes of this Agreement
all CONFIDENTIAL INFORMATION disclosed by the other Party under the Agreement,
except as may be otherwise provided herein. Notwithstanding the foregoing, a
Party may disclose the other Party's CONFIDENTIAL INFORMATION to those of its
AFFILIATES, permitted sublicensees, directors, officers, employees, agents,
consultants and clinical investigators that have a need to know such INFORMATION
in order to achieve the purposes of this Agreement, provided that such Party
will obtain prior agreement from its AFFILIATES, permitted sublicensees,
directors, officers, employees, agents, consultants or clinical investigators to
whom disclosure is to be made to hold in confidence and not make use of such
CONFIDENTIAL INFORMATION for any purpose other than those permitted by this
Agreement. Each Party will promptly notify the other upon discovery of any
unauthorized use or disclosure of the CONFIDENTIAL INFORMATION.

      10.3 AUTHORIZED DISCLOSURE. Each Party may disclose CONFIDENTIAL
INFORMATION of the other Party to THIRD PARTIES solely to the extent such
disclosure is reasonably necessary in filing or prosecuting patent applications,
prosecuting or defending litigation or complying with applicable laws,
governmental regulations or court orders, provided that such Party will give
reasonable advance notice to the other Party of such disclosure requirement and
shall give the other Party sufficient opportunity to object to such disclosure
or to secure confidential treatment of such CONFIDENTIAL INFORMATION required to
be disclosed to the extent that such is available. Either Party may disclose
(subject to the confidentiality restrictions contained herein) CONFIDENTIAL
INFORMATION to THIRD PARTIES to the extent necessary to perform its obligations
under this Agreement, provided such THIRD PARTIES execute confidentiality
agreements containing terms no less strict than those contained herein. Further,
nothing in this Article 9 shall be construed as preventing or in any way
inhibiting either Party from complying with statutory and regulatory
requirements governing the development, manufacture, use and sale or other
distribution of any PRODUCT in any manner consistent with the terms of this
Agreement, provided that any such compliance that requires disclosing to
regulatory authorities confidential or other information received from the other
Party may be made only if such Party provides reasonable advance notice of such
disclosure to the other Party and makes reasonable efforts to obtain
confidential treatment of such confidential information if requested by the
other Party to the extent that such is available.

      10.4 PUBLICATION. Aradigm shall not submit for written or oral publication
any manuscript, abstract or the like which includes data or other information
relating to any PRODUCT without first obtaining the prior written consent of SB,
which consent shall not be

unreasonably withheld. Aradigm shall send such publications to SB in the English
language if practicable. SB shall not submit for written or oral publication any
manuscript, abstract or the like which includes data or other information
relating to PRODUCT without first obtaining the prior written consent of
Aradigm, which consent shall not be unreasonably withheld. The Parties agree to
review and comment within thirty (30) working days on any such draft
publication. Each Party shall use its DILIGENT EFFORTS to bind the clinical
investigators and other agents it utilizes for the DEVELOPMENT of PRODUCT in its
particular territory to a provision similar to this Section, provided that it is
understood that a Party's inability to bind a clinical investigator to such a
similar provision shall not prohibit such party from utilizing such clinical
investigator. The contribution of each Party shall be noted in all publications
or presentations by acknowledgment or coauthorship, whichever is appropriate.

      10.5 CONFIDENTIALITY ISSUES IN BANKRUPTCY. In the event that a court or
other legal or administrative tribunal, directly or through an appointed master,
trustee or receiver, assumes partial or complete control over the assets of a
Party to this Agreement based on the insolvency or bankruptcy of such Party, the
bankrupt or insolvent Party shall promptly notify the court or other tribunal
(a) that confidential information received from the other Party under this
Agreement remains the property of the other Party and (b) of the confidentiality
obligations under this Agreement with respect to such information. In addition,
the bankrupt or insolvent Party shall, to the extent permitted by law, take all
steps necessary or desirable to maintain the confidentiality of the other
Party's confidential information and to seek to ensure that the court, other
tribunal or appointee maintains such information in confidence in accordance
with the terms of this Agreement.

governmental authorities and other entities and persons required to be obtained
by Aradigm in connection with entry into this Agreement.

            (e) ARADIGM PATENTS. To Aradigm's knowledge, as of the Effective
Date, the manufacture, use or sale of the PRODUCTS in the FIELD will not violate
the intellectual property rights of any THIRD PARTY, and Aradigm has no present

representation or warranty that the ARADIGM PATENTS are valid or enforceable, or
that they will be so during the term of this Agreement.

            (f) NO CONFLICT. No agreement between Aradigm and a THIRD PARTY in

prevent Aradigm from performing its obligations under this Agreement or granting
to SB the rights granted hereunder.

            (g) DATA REGARDING PRODUCTS. Aradigm has no present knowledge of the

of any court, governmental body or administrative or other agency having
jurisdiction over it.

            (d) NO CONFLICT. No agreement between SB and a THIRD PARTY in
existence as of the Effective Date would prevent SB from performing its
obligations under this Agreement or granting to Aradigm the rights granted
hereunder, and SB shall not enter into any such THIRD PARTY agreement that would
prevent SB from performing its obligations under this Agreement or granting to
Aradigm the rights granted hereunder.

      11.3  CERTAIN ADDITIONAL COVENANTS.

            (a) Aradigm shall pay all royalties or other sums that Aradigm may
owe to any THIRD PARTY by virtue of its activities under this Agreement, and
shall perform and observe all of the other material obligations under all
present and future agreements between Aradigm and any THIRD PARTY that are in
any way related to Aradigm's ability to grant the rights Aradigm has granted to
SB under this Agreement or to Aradigm's ability to perform its obligations to SB
under this Agreement. In the event that Aradigm receives notice from any such
THIRD PARTY that Aradigm has committed a breach of its obligations under any
such agreement, or if Aradigm anticipates such breach, which breach may give
rise to a right by such THIRD PARTY to terminate or materially diminish
Aradigm's rights to PATENTS and/or INFORMATION in the FIELD licensed to Aradigm,
which PATENTS and/or INFORMATION are sublicensed to SB hereunder, or otherwise
to diminish materially Aradigm's ability to perform its obligations to SB under
this Agreement, Aradigm shall immediately notify SB of such situation, and
Aradigm shall promptly cure such breach. However, if Aradigm is unable to cure
such breach, Aradigm shall, to the extent possible, permit SB to cure such
breach on Aradigm's behalf.

            (b) SB shall pay all royalties or other sums that SB may owe to any
THIRD PARTY by virtue of its activities under this Agreement, and shall perform
and observe all of the other material obligations under all present and future
agreements between SB and any THIRD PARTY that are in any way related to SB's
ability to perform its obligations to Aradigm under this Agreement. In the event
that SB receives notice from any such THIRD PARTY that SB has committed a breach
of its obligations under any such agreement, or if SB anticipates such breach,
which breach may give rise to a right by such THIRD PARTY to terminate or
materially diminish SB's rights under such agreement or otherwise to diminish
materially SB's ability to perform its obligations to SB under this Agreement,
SB shall immediately notify Aradigm of such situation, and SB shall promptly
cure such breach. However, if SB is unable to cure such breach, SB shall, to the
extent possible, permit Aradigm to cure such breach on SB's behalf.

            (c) Aradigm agrees that Aradigm and its AFFILIATES shall not
knowingly conduct any development work, either themselves or in conjunction with
any other licensees or partners, on the AERx DEVICE or DRUG PRODUCTS for use
outside the FIELD; provided that the foregoing shall not be interpreted to
prevent Aradigm or its AFFILIATES or other licensees from developing other
Aradigm pulmonary drug delivery products, including products based on the AERx
design or technology, for use outside the FIELD and shall not limit Aradigm's
rights under Section 2.9.

12.   INDEMNIFICATION.

      12.1 INDEMNIFICATION BY ARADIGM. Subject to compliance with Section 12.3,
Aradigm agrees to indemnify, defend and hold harmless SB, its AFFILIATES, and
their respective officers, directors, shareholders, representatives, agents and

attributable to or caused by the acts or omissions of Aradigm or its AFFILIATES
or their respective officers, directors, representatives, agents or employees,
[*] or (c) breach of any representation or warranty of Aradigm in Section 11.1

this Section 12.1 with respect to any Losses resulting from (1) the negligent or
intentionally wrongful act or omission of the SB, its AFFILIATES or their
respective officers, directors, representatives, agents or employees, (2) the
improper storage, transportation, marketing, training, or handling of a PRODUCT
by any person or entity other than Aradigm, its AFFILIATES or their respective
officers, directors, representatives, agents or employees, (3) the improper use
of a PRODUCT by any person or entity other than Aradigm, its AFFILIATES or their
respective officers, directors, agents or employees, or (4) a Defective
Marketing Claim (as defined in Section 12.2). With respect to any THIRD PARTY
claim, suit or action based upon death or injury to any person or damage to any
property based on use of an AERx SYSTEM, AERx DEVICE, DRUG PRODUCT or ACCESSORY,
Aradigm agrees to provide SB, at SB's expense, with reasonable assistance in
SB's defense of such claim, suit or action.

      12.2 INDEMNIFICATION BY SB. Subject to compliance with Section 12.3, SB
agrees to indemnify and defend Aradigm, its AFFILIATES, and their respective
officers, directors, shareholders, representatives, agents and employees (the
"Aradigm Indemnitees"), from and against any and all Losses (as defined in
Section 12.1) resulting from a THIRD PARTY claim, suit or action based upon: (a)
death or injury to any person or damage to any property to the extent caused by
the defective or negligent marketing or promotion of a PRODUCT by SB or its
AFFILIATES hereunder (a "Defective Marketing Claim"); (b) harm or damage
attributable to or caused by the acts or omissions of SB or its AFFILIATES or
their respective officers, directors, representatives, agents or employees, [*]
or (b) breach or any representation or warranty of SB in Section 11.2 hereof.

12.2 with respect to any Losses resulting from (1) the negligent or
intentionally wrongful act or omission of Aradigm, its AFFILIATES or their
respective officers, directors, representatives, agents or employees, (2) the
improper storage, transportation, marketing, training, or handling of a PRODUCT
by entities or persons other than SB or its sublicensees or their respective
AFFILIATES, or their respective officers, directors, representatives, agents or
employees, (3) the improper use of a PRODUCT, unless caused by SB or its
sublicensees or their respective AFFILIATES, or their respective officers,

THIRD PARTY claim, suit or action based upon death or injury to any person or
damage to any property based on use of a PRODUCT, SB agrees to provide Aradigm,
at Aradigm's expense, with reasonable assistance in Aradigm's defense of such
claim, suit or action.

      12.3 INDEMNITY PROCEDURE. In the event that a Party is seeking
indemnification under Section 12.1 or 12.2, it shall inform the other Party (the
"Indemnifying Party") of a claim as soon as reasonably practicable after it
receives notice of the claim, shall permit the Indemnifying Party to assume
direction and control of the defense of the claim (including the right to settle
the claim solely for monetary consideration), and, at the Indemnifying Party's
expense, shall cooperate as reasonably requested in the defense of the claim.
The Indemnified Party shall have the right to retain its own counsel, subject to
the approval of any such outside counsel by the Indemnifying Party, with the
fees and expenses to be paid by the Indemnifying Party if representation of such
Party by the counsel retained by Indemnifying Party would be inappropriate due
to actual or potential differing interests between such indemnitee and any other
party represented by such counsel in such proceedings. The Indemnifying Party
may not settle such action or claim, or otherwise consent to an adverse judgment
in such action or claim, without the express written consent of the Indemnified
Party if such settlement or adverse judgment diminishes the rights or interests
of the Indemnified Party.

      12.4 LIMITATION OF LIABILITY. IN NO EVENT SHALL EITHER PARTY, ITS
DIRECTORS, OFFICERS, EMPLOYEES, AGENTS OR AFFILIATES BE LIABLE TO THE OTHER
PARTY FOR ANY INDIRECT, INCIDENTAL, OR CONSEQUENTIAL DAMAGES, WHETHER BASED UPON
A CLAIM OR ACTION OF CONTRACT, WARRANTY, NEGLIGENCE, STRICT LIABILITY OR OTHER
TORT, OR OTHERWISE, ARISING OUT OF THIS AGREEMENT.

      12.5 LIABILITY INSURANCE. Immediately upon the launch of AERx SYSTEM in
the TERRITORY by SB, its AFFILIATES or its sublicensees, and for a period of [*]
after the expiration or earlier termination of this Agreement, each Party shall
obtain and/or maintain, respectively, at its sole cost and expense, and in the
case of ARADIGM, from insurance companies reasonably satisfactory to SB, product
liability insurance and contractual liability coverage, in amounts,
respectively, which are reasonable and customary in the U.S. pharmaceutical
industry for companies of comparable size and activities at the respective place
of business of each party. Such product liability insurance shall insure against
personal injury, physical injury, or property damage arising out of the
manufacture, sale, distribution, or marketing of AERx SYSTEM in the TERRITORY.
Each Party shall provide written proof of the existence of such insurance to the
other Party upon request. Notwithstanding the foregoing, during the period
specified above ARADIGM shall maintain product liability insurance with a
minimum of [*] per occurrence (or claim) and annual aggregate limit of
liability.

13.   DISPUTE RESOLUTION; ARBITRATION.

      13.1 DISPUTE RESOLUTION PROCESS. If a dispute or controversy regarding any
right or obligation under this Agreement arises between the Parties, the Parties
will seek to resolve such dispute or controversy or failure to agree by good
faith negotiation and DILIGENT EFFORTS 

* Certain information on this page has been omitted and filed
  separately with the Commission. Confidential treatment has
  been requested with respect to the omitted portions.


                                       63.

between senior management representatives of the Parties, to be commenced
promptly after such dispute or controversy or failure to agree arises. If such
dispute or controversy or failure to agree is not resolved by such negotiation
within thirty (30) days of notice by one Party to the other, and at least one
Party requires such resolution, then the Parties shall proceed as follows. Any
unresolved dispute, controversy, action, claim or proceeding initiated by either
Party (other than a THIRD PARTY action, claim or other proceeding in a bona fide
action, claim or other proceeding initiated by a THIRD PARTY against a Party)
relating to, arising out of or resulting from this Agreement, or the performance
by either Party of its obligations hereunder, or any alleged breach, termination
or invalidity of this Agreement, whether before or after termination or
expiration of this Agreement, shall be finally resolved by binding arbitration.
Whenever a Party shall decide to institute arbitration proceedings, it shall
give written notice to that effect to the other Party. The Parties agree that
the service of any notice in the course of such arbitration proceeding at their
respective addresses as provided for in Section 15.5 below shall be valid and
sufficient. Any arbitration hereunder shall be conducted under the then existent
Rules of Commercial Arbitration of the American Arbitration Association. Each
such arbitration shall be conducted in the English language by a panel of three
arbitrators appointed in accordance with such rules, and shall be held in San
Francisco, California if SB has initiated the arbitration, or in Philadelphia,
Pennsylvania if Aradigm has initiated the arbitration. The arbitrators shall
have the authority to grant specific performance, and to allocate between the
Parties the costs of arbitration in such equitable manner as they determine,
provided that no punitive damages will be recoverable by either Party in such a
proceeding. The decision of the Arbitration Tribunal in any such arbitration
shall be final and not appealable, and shall be enforceable in any court of
competent jurisdiction or application may be made to such court for judicial
acceptance of any award and an order of enforcement, as the case may be. Each
Party hereby consents to the jurisdiction of the federal courts of the United
States in New York, New York for the purposes of enforcing the decisions entered
pursuant to an arbitration hereunder and for enforcing the agreements between
the Parties reflected in this Section 13.1. In no event shall a demand for
arbitration be made after the date when institution of a legal or equitable
proceeding based upon such claim, dispute or other matter in question would be
barred by the applicable statute of limitations. Notwithstanding the foregoing,
either Party may at any time seek equitable relief before any court having
jurisdiction, pending resolution of the underlying issue or dispute pursuant to
the terms of this Section 13.1.

      13.2  GOVERNING LAW. This Agreement will be governed by and interpreted
in accordance with the laws of the State of New York, without regard to
conflicts of laws principles.

14.   TERM OF AGREEMENT AND TERMINATION.

      14.1 TERM. Unless earlier terminated as provided in this Article 13 or
under Sections 2.6 or 5.5 or 15.1, this Agreement shall terminate in the
TERRITORY with respect to a particular AERx SYSTEM ten (10) years from the date
of commercial launch by or on behalf of SB of such AERx SYSTEM [*] provided
however that if such commercial launch of the AERx SYSTEM [*] occurs [*] years
or more after commercial launch of such AERx SYSTEM by or on behalf of SB in [*]

                                      64.
<PAGE>   70
 such termination will occur thirteen (13) years from the date of the commercial
launch of such AERx SYSTEM in the last of such [*] Upon such termination with
respect to a particular AERx SYSTEM, all SB's rights hereunder to purchase,
market, distribute, promote, offer for sale and sell such AERx SYSTEM in any
country in the TERRITORY shall terminate, unless otherwise agreed by the Parties
in writing. Unless terminated earlier in accordance with this Article 14 or
Sections 2.6 or 5.5, this Agreement shall expire in its entirety on the
termination of the Agreement with respect to all AERx SYSTEMS, as provided
above. The Parties agree that at least [*] with respect to a particular AERx
SYSTEM, or the expiration of the Agreement, the Parties will meet, discuss in
good faith and attempt to reach mutually acceptable agreement to provide for an
extension of the licenses granted hereunder and Aradigm's continuing supply to
SB of such AERx SYSTEM and commercially viable economic terms for such supply.
In the event that the Parties do not reach agreement on Aradigm's continuing
supply to SB of PRODUCTS by the date [*] the Parties will discuss in good faith
the amount of residual payments, if any, that Aradigm would pay to SB based on
sales of PRODUCTS by Aradigm, its AFFILIATES and licensees during [*] such
termination of the Agreement.

      14.2 TERMINATION FOR MATERIAL BREACH. Each Party shall have the right to
terminate this Agreement after written notice to the other that the other is in
material breach of this Agreement, unless the other Party cures the breach
before the expiration of ninety (90) days, thirty (30) days in the case of a
delayed payment, after such written notice.

      14.3 TERMINATION BY SB. Commencing on the first anniversary of the
Effective Date, SB may terminate this Agreement in its entirety, on written
notice to Aradigm as provided below, in the event that SB reasonably determines,
using the same standards SB uses in assessing whether or not to continue
development or marketing of its own internally-invented products, that the
patent, medical/scientific, technical, regulatory, or commercial profile of the
PRODUCTS do not justify continued development and/or marketing, as applicable,
of the PRODUCTS. If SB elects to terminate the Agreement under this Section 14.3
prior to launch of commercial marketing of any PRODUCTS, SB must give Aradigm
[*] advance written notice of its intention to terminate, and such termination
will be effective at the end of such [*] notice period. During such period, 
[*] during such period by Aradigm within the agreed BUDGET for the DEVELOPMENT
work to be conducted in the period provided that in the event there is any [*]
as recorded in the report for such period to be provided to SB by Aradigm 
under Section 2.4, [*] within thirty (30) days after [*] therefor. If SB elects
to terminate the Agreement under this Section 14.3 after commercial launch of
any PRODUCTS, SB must give Aradigm [*] advance written notice of its intention
to terminate, and such termination will be effective at the end of such [*]
notice period. SB may continue to sell any PRODUCTS remaining in its inventory
during such notice period, but such right to continue selling PRODUCTS shall
terminate upon termination of the Agreement at the end of such notice period.

if, at any time, the other party shall file in any court or agency pursuant to
any statute or regulation of any state or country, a petition in bankruptcy or
insolvency or for reorganization or for an arrangement or for the appointment of
a receiver or trustee of the party or of its assets, or if the other party
proposes a written agreement of composition or extension of its debts, or if the
other party shall be served with an involuntary petition against it, filed in
any insolvency proceeding, and such petition shall not be dismissed with sixty
(60) days after the filing thereof, or if the other party shall propose or be a
party to any dissolution or liquidation, or if the other party shall make an
assignment for the benefit of creditors.

      14.5 CONSEQUENCES OF TERMINATION. Upon the expiration or any termination
of this Agreement, (i) [*] develop, make, use and sell PRODUCTS in the FIELD; 
and (ii) SB shall destroy and shall not retain any copies of any CONFIDENTIAL
INFORMATION provided by Aradigm hereunder, except that SB's legal department may
retain one copy thereof solely for archival purposes. Further, if Aradigm
terminates the Agreement under Section 2.6, 5.5 or 14.2 or SB terminates the
Agreement under Section 14.3, then immediately upon such termination [*] the
PRODUCTS and any additional Aradigm products for use in the FIELD that comprise
modifications to existing products or are additional ANALGESIC DRUG products for
use in the FIELD.

      14.6 ACCRUED RIGHTS, SURVIVING OBLIGATIONS. Termination of this Agreement
shall terminate all licenses granted hereunder (except as provided in this
Section 13.4), but shall not affect any rights to payment or other rights that
accrued prior to the date of termination. Additionally, the terms of Section 9.1

of the following Sections shall survive any termination of this Agreement, to
the extent provided in the following: 3.2; 3.3; 5.2; 6.12(a), (b), (d), (f) and

insolvency of Aradigm, SB shall be entitled to retain the license rights and
licenses granted herein, subject to SB's performance of all its obligations
under the Agreement and to Aradigm's rights to terminate this Agreement for

Agreement.

            (b) All license rights and licenses granted under or pursuant to
this Agreement under PATENTS and INFORMATION, including know-how and trade

rights to "intellectual property" as defined under Section 101(52) of the U.S.
Bankruptcy Code. Each Party agrees that the other Party as a licensee of such
rights under this Agreement, shall retain and may fully exercise all of its
rights and elections under the U.S. Bankruptcy Code, subject to performance by
such electing Party of its preexisting obligations under this Agreement.

15.   MISCELLANEOUS.

      15.1 HART-SCOTT-RODINO COMPLIANCE. Upon the date that there is mutual
execution of the Agreement, SB and Aradigm shall simultaneously notify the
Agreement and the Stock Purchase Agreement (as described in Paragraph D of the
Recitals hereof) to the Federal Trade Commission in accordance with the
requirements of the Hart-Scott-Rodino Antitrust Improvements Act (the "Act"). SB
shall pay the forty five thousand U.S. dollar (U.S. $45,000) fee required for
such notification. The date of the expiration or earlier termination of the
applicable waiting period required by the Act after such notification shall be
referred to as the "HSR Approval Date". In the event that the FTC shall formally
request additional information which thereby extends the termination of the
applicable waiting period beyond thirty (30) days after the initial notification
under the Act, the parties shall promptly meet to determine, in good faith, the
appropriate response to such request. In the event the HSR Approval Date has not
occurred within ninety (90) days after the Parties' initial notification under
the Act, then either Party may elect to terminate this Agreement on written
notice to be provided no later than twenty (20) days after the end of such
ninety (90) day period, and no payment shall be due to Aradigm under this
Agreement or the Stock Purchase Agreement upon such termination.

      15.2 PRESS RELEASES; DISCLOSURE OF AGREEMENT. Upon signing the Agreement,
Aradigm will issue the press release set forth in Exhibit D attached hereto. No
public announcement or other disclosure to THIRD PARTIES concerning the terms of
this Agreement shall be made, either directly or indirectly, by any Party to
this Agreement, except as may be legally required or as may be required for
recording purposes, without first obtaining the written approval of the other
Party and agreement upon the nature and text of such announcement or disclosure,
provided that this requirement shall not be applicable (a) to any public
announcement or other disclosure concerning the existence of or terms of this
Agreement to the extent that the information in such public announcement or
other disclosure was already the subject of a written approval under this
provision, or (b) to disclosure by [*] provided that, prior to any such
disclosure, such THIRD PARTY [*] with respect to such disclosure. The Party

desiring to make any such public announcement or other disclosure shall inform
the other Party of the proposed announcement or disclosure in reasonably
sufficient time prior to public release, and shall provide the other Party with
a written copy thereof, in order to allow such other Party to comment upon such
announcement or disclosure. Each Party agrees that it shall cooperate fully with
the other with respect to all disclosures regarding this Agreement to the
Securities Exchange Commission and any other governmental or regulatory
agencies, including requests for confidential treatment of proprietary
information of either Party included in any such disclosure.

      15.3 RECORDATION. Subject to compliance with all confidentiality
obligations of SB under this Agreement, SB shall have the right, at any time, to
record or register this Agreement in appropriate governmental or regulatory
offices anywhere in the TERRITORY, and Aradigm shall provide reasonable
assistance to SB in effecting such recording or registration, provided that SB
shall take appropriate measures available to protect the confidentiality of the
terms of the Agreement.

      15.4 ENTIRE AGREEMENT; AMENDMENT. This Agreement, and the existing
Confidentiality Agreements between the Parties related to the subject matter of
this Agreement, and the Stock Purchase Agreement between the Parties which is
effective as of the Effective Date, sets forth the terms of the collaboration
agreement between the Parties hereto and, except as otherwise set forth herein,
supersedes and terminates all prior representations, agreements and
understandings between the Parties regarding the subject matter hereof. Any
modification of this Agreement shall be effective only when in writing and
signed by the Parties, and specifically stating that it is an amendment to this
Agreement.

      15.5 ASSIGNMENT. This Agreement and the licenses and rights herein granted
shall be binding upon and inure to the benefit of the successors in interest of
the respective Parties. Neither Party may assign or transfer this Agreement or
any rights or obligations hereunder without the prior written consent of the
other Party, which consent shall not be unreasonably withheld, except that SB
may make such an assignment without Aradigm consent to AFFILIATES or to a
successor to all or substantially all of the related business assets of SB
relating to this Agreement, whether by way of a merger, sale of stock, sale of
assets or other similar transaction.

      15.6 NOTICES. Any notice required or permitted to be given under this
Agreement shall be in writing, shall specifically refer to this Agreement and

      15.7 SEVERABILITY. If any Article or part thereof of this Agreement is
declared invalid by any court of competent jurisdiction, or any government or
other agency having jurisdiction over either Aradigm or SB deems any Article or
part thereof to be contrary to any anti-trust or competition laws then such
declaration shall not affect the remainder of the Article or other Articles. To
the extent possible the Parties shall revise such invalidated Article or part
thereof in a manner that will render such provision valid without impairing the
Parties' original intent. In the event a Party's rights are materially affected
as a result of a change in this Agreement under this Paragraph, the Parties will
renegotiate the terms and conditions of this Agreement to resolve any
inequities.

      15.8 FORCE MAJEURE. Except as otherwise provided herein, no Party shall be
in breach of this Agreement, or liable to the other Party, for any delay or
failure of performance to the extent such delay or failure is caused by
circumstances beyond its reasonable control and that by the exercise of DILIGENT
EFFORTS it is unable to prevent, provided that the party claiming excuse uses
its DILIGENT EFFORTS to overcome the same.

      15.9 EXPENSES. Except as otherwise provided in the Agreement, all expenses
incurred by SB in connection with its obligations under this Agreement will be
borne solely by SB and all expenses incurred by Aradigm in connection with its
obligations under this Agreement will be 



                                      69.
<PAGE>   75

borne solely by Aradigm. Each Party will be responsible for appointing its own
employees, agents and representatives, who will be compensated by such Party.
Each Party will be responsible for paying any finder's or broker's fee owed to a
THIRD PARTY that such Party incurs based directly or indirectly on negotiating
and entering this Agreement, and shall indemnify the other Party against any
obligation to pay such fee.

      15.10 NON-WAIVER. The failure of a Party in any one or more instances to
insist upon strict performance of any of the terms and conditions of this
Agreement shall not be construed as a waiver or relinquishment, to any extent,
of the right to assert or rely upon any such terms or conditions on any future
occasion.

      15.11 DISCLAIMER OF AGENCY/RELATIONSHIP OF THE PARTIES. This Agreement
shall not constitute any Party the legal representative or agent of another, nor
shall any party have the right or authority to assume, create, or incur any
THIRD PARTY liability or obligation of any kind, express or implied, against or
in the name of or on behalf of another except as expressly set forth in this
Agreement. The relationship between Aradigm and SB under this Agreement is that
of independent contractors. Aradigm and SB are not joint venturers, partners,
principal and agent, master and servant, employer or employee, and have no
relationship other than as independent contracting Parties. Aradigm shall have
no power to bind or obligate SB in any manner. Likewise, SB shall have no power
to bind or obligate Aradigm in any manner. Neither Party shall have any
responsibility for the hiring, firing, compensation or employee benefits of the
other Party's employees.

      15.12 PERFORMANCE BY AFFILIATES. SB hereby covenants that its AFFILIATES
shall comply with all obligations under this Agreement to the same extent as if
such AFFILIATES were SB hereunder. SB shall be responsible for any breach by its
AFFILIATES of the obligations set forth herein. Aradigm hereby covenants that

                 ARADIGM AND SMITHKLINE BEECHAM SIGN WORLDWIDE
                     COMMERCIALIZATION AGREEMENT TO DEVELOP
                        AERx(TM) PAIN MANAGEMENT SYSTEM

        HAYWARD, CALIFORNIA, SEPTEMBER 30, 1997.  Aradigm Corporation (NASDAQ:
ARDM) announced today that it has signed an agreement with SmithKline Beecham
(SB) to develop and commercialize a pulmonary drug delivery system for
providing immediate pain relief using opiates and opioids. The hand-held
AERx(TM) Pain Management System, an "electronic inhaler," is being designed to
combine proprietary pulmonary delivery technology with disposable liquid drug
packets to deliver medication rapidly and reproducibly into the bloodstream via
the lung. The collaboration represents the first commercial application of
Aradign's AERx platform technology. Pivotal clinical trials with morphine
sulfate, the first product targeted for commercialization, are expected to
start in 1998. Aradigm and SB also executed a stock purchase agreement under
which SB has agreed to purchase newly issued Aradigm common stock in two
transactions, the first of which will occur once the agreements become
effective at a 25% premium to Aradigm's recent market price.

        Under the terms of the agreements, by the time the first product is
commercialized, Aradigm could receive approximately $40 million in milestones,
development payments and equity investments. Aradigm will receive $9 million in
upfront payments and a $5 million equity investment once the agreements become
effective. Additional milestones and development costs would be paid if SB
decides to develop additional opiates and opioids for delivery with the AERx
Pain Management System. In exchange, SB will have exclusive worldwide
commercial rights to the AERx Pain Management System for use with such
analgesics. Aradigm will be the manufacturer of all the products covered by
this agreements and will also receive royalties on net sales. The agreements
between Aradigm and SB will become effective upon clearance of a filing under
the Hart-Scott-Rodino Antitrust Improvements Act.

        Poorly treated pain is a major problem which is receiving increasing
attention from the medical community. Among cancer patients, over 4 million
people worldwide suffer from pain, a majority of whom experience multiple
"breakthrough" pain events each day. Breakthrough pain refers to acute
exacerbations of paid which "break through" the patient's normal baseline


                                       1.

level of pain medication. In the postoperative arena, 20 million patients each
year require treatment with narcotics after surgery. Many of these patients in
pain are underserved by currently available treatments. The limitations include
painful and costly intravenous (IV) administrations and injections, slow onset
of action even with the more "immediate release" oral products, as well as
misuse and safety concerns. The AERx Pain Management System is being
specifically designed to address these problems and improve patients' quality of
life. AERx technology has the potential to deliver pain relief as rapidly and
effectively as the current "gold standard" of care, intravenous
patient-controlled analgesia, without needles. In a Phase I trial in healthy
volunteers, the speed and reproductibility of morphine delivery using the AERx
technology was comparable to morphine delivered intravenously.

     The non-invasive, self-administered nature of the AERx Pain Management
System, with confirmation from planned clinical studies, offers the possibility
that it may be usable in both hospital and outpatient settings. This may reduce
healthcare costs by allowing patients to leave the hospital earlier and treat
their postoperative pain at home. Unlike other pain management products, the
AERx Pain Management System is being designed in include patented electronic
"lock and key" technology for proper patient identification to prevent
overdosing and misuse, and will automatically record all dosage events.

     "Aradigm is developing this product to provide a safe, self-administered
drug delivery system to treat patients that suffer from poorly treated chronic
or acute pain. We are delighted to be collaborating with one of the world's
leading pharmaceutical companies on this product," stated Richard P. Thompson,
president and CEO of Aradigm. "The agreement with SmithKline Beecham validates
Aradigm's approach to advanced pulmonary drug delivery, and is consistent with
our strategy of forming alliances with world-class corporate partners."

     "There remains a tremendous need to improve upon current methods of
alleviating pain," said Dr. Jerry Karabelas, executive vice president,
SmithKline Beecham Pharmaceuticals. "We are eager to work as partners with
Aradigm in realizing the potential of a technology that may bring relief to so
many patients."

     Located in Hayward, California, Aradigm is engaged in the development of
novel, pulmonary drug delivery systems designed to enhance the delivery and
effectiveness of a number of existing and development stage drugs and reduce the
need for injectable drug therapy. Aradigm plans to commercialize its proprietary
technologies on two product platforms; the SmartMist(TM) Respiratory Management
System, which is designed to improve the effectiveness of treatment provided by
metered dose inhalers; and the AERx(TM) Pulmonary Drug Delivery System, which
creates aerosols from liquid drug formulations for delivery locally to the lung
or into the bloodstream via the lung.

discovers, develops, manufactures, and markets pharmaceuticals, vaccines,
over-the-counter medicines, and health-related consumer products, and

any of the following events:

                      (i) all or substantially all of the assets of Aradigm 
are sold, leased, exchanged or otherwise transferred to any other person or
group of persons acting in concert as a partnership or other group (a "Group")
other than an affiliate of Aradigm;

                      (ii) Aradigm is merged or consolidated with or into
another entity with the effect that the existing equity holders hold less than
50% of the combined voting power of the then outstanding securities ordinarily
(and apart from rights arising under special circumstances) having the right to
vote in the election of directors (or in the election of persons serving in a



                                       9.

similar capacity) of the surviving entity of such merger or the entity resulting
from such consolidation.

                      (iii)  a change in the composition of the board of 
directors of Aradigm as a result of which during any period of two consecutive
years after the First Closing, individuals who at the beginning of such period
constitute Aradigm's Board of Directors (together with any new director whose
election by Aradigm's Board of Directors or whose nomination for election by
Aradigm's shareholders was approved by a vote of at least two-thirds of the
directors then still in office who either were directors at the beginning of
such period or whose election or nomination for election was previously so
approved) cease for any reason to constitute a majority of the directors in
office at the end of such period; or

                      (iv) a person or Group shall, as a result of a tender or
exchange offer, open market purchases, merger, privately negotiated purchases or
otherwise, have become, directly or indirectly, the beneficial owner (within the
meaning of Rule 13d-3 under the Securities Exchange Act of 1934, as amended) of
the securities of Aradigm representing 50% or more of the combined voting power
of the then outstanding securities of Aradigm ordinarily (and apart from rights
arising under special circumstances) having the right to vote in the election of
directors.

               (h) Aradigm shall not have (i) filed in any court or agency
pursuant to any statute or regulation of any state or country, a petition in
bankruptcy or insolvency or for reorganization or for an arrangement or for the
appointment of a receiver or trustee of the party or of its assets, or (ii) been
served with an involuntary petition against it, filed in any insolvency
proceeding, which petition has not been dismissed as of the Second Closing Date.

        5.2 CONDITIONS TO OBLIGATIONS OF ARADIGM. Aradigm's obligation to issue
and sell the Additional Shares at the Second Closing is subject to the
fulfillment to Aradigm's satisfaction, on or prior to the Second Closing, of the
following conditions:

               (a) REPRESENTATIONS AND WARRANTIES TRUE. The representations and
warranties made by SB in Section 3 hereof shall be true and correct at the date
of the Second Closing, with the same force and effect as if they had been made
on and as of said date.

               (b) PERFORMANCE OF OBLIGATIONS. SB shall have performed and
complied with all agreements and conditions herein required to be performed or
complied with by it on or before the Second Closing.

of the United States or of any state that are required in connection with the
lawful sale and issuance of the Additional Shares pursuant to this Agreement
shall have been duly obtained and shall be effective on and as of the Second
Closing. No stop order or other order enjoining the sale of the Additional
Shares shall have been issued and no proceedings for such purpose shall be
pending or, to the knowledge of Aradigm, threatened by the SEC or any
commissioner of corporations or similar officer of any state having jurisdiction
over this transaction. At the time of the Second Closing, the sale and 



                                      10.
<PAGE>   11

issuance of the Additional Shares shall be legally permitted by all laws and
regulations to which SB and Aradigm are subject.

6.      MISCELLANEOUS.

under the laws of the State of California as applied to agreements among
California residents, made and to be performed entirely within the State of
California.

        6.2 SUCCESSORS AND ASSIGNS. Except as otherwise expressly provided
herein, the provisions hereof shall inure to the benefit of, and be binding
upon, the successors, assigns, heirs, executors, and administrators of the
parties hereto.

        6.3 ENTIRE AGREEMENT. This Agreement, the Development Agreement, and the
Exhibits hereto and thereto, and the other documents delivered pursuant hereto
constitute the full and entire understanding and agreement among the parties
with regard to the subjects hereof, and no party shall be liable or bound to any
other party in any manner by any representations, warranties, covenants, or
agreements except as specifically set forth herein or therein. Nothing in this
Agreement, express or implied, is intended to confer upon any party, other than
the parties hereto and their respective successors and assigns, any rights,
remedies, obligations, or liabilities under or by reason of this Agreement,
except as expressly provided herein.

        6.4 SEPARABILITY. In case any provision of this Agreement shall be
invalid, illegal, or unenforceable, it shall, to the extent practicable, be
modified so as to make it valid, legal and enforceable and to retain as nearly

be binding upon SB, each future holder of the Shares, and Aradigm.

        6.6 DELAYS OR OMISSIONS. No delay or omission to exercise any right,
power, or remedy accruing to SB or any subsequent holder of any Shares upon any
breach, default or noncompliance of Aradigm under this Agreement, shall impair
any such right, power, or remedy, nor shall it be construed to be a waiver of
any such breach, default or noncompliance, or any acquiescence therein, or of
any similar breach, default or noncompliance thereafter occurring. It is further
agreed that any waiver, permit, consent, or approval of any kind or character on
SB's part of any breach, default or noncompliance under this Agreement or any
waiver on SB's part of any provisions or conditions of this Agreement must be in
writing and shall be effective only to the extent specifically set forth in such

c/o SmithKline Beecham Corporation 
One Franklin Plaza (FP 1935) 
Philadelphia, PA 19102

RE:     ARADIGM CORPORATION

Ladies and Gentlemen:

We have acted as counsel to Aradigm Corporation, a California corporation (the
"Company"), in connection with the issuance and sale to you of the Initial
Shares (as defined in the Stock Purchase Agreement between you and the Company,
dated as of September ___, 1997 (the "Purchase Agreement")), such issuance and
sale to take place pursuant to the terms and conditions of the Purchase
Agreement. We are rendering this opinion pursuant to Section 5.1(b) of the
Purchase Agreement. Except as otherwise defined herein, capitalized terms used
but not defined herein have the respective meanings given to them in the
Purchase Agreement.

In connection with this opinion, we have examined and relied upon the
representations and warranties as to factual matters contained in and made
pursuant to the Agreement by the various parties and originals or copies
certified to our satisfaction, of such records, documents, certificates,
opinions, memoranda and other instruments as in our judgment are necessary or
appropriate to enable us to render the opinion expressed below. Where we render
an opinion "to the best of our knowledge" or concerning an item "known to us" or
our opinion otherwise refers to our knowledge, it is based solely upon (i) an
inquiry of attorneys within this firm who perform legal services for the
Company, (ii) receipt of a certificate executed by an officer of the Company
covering such matters, and (iii) such other investigation, if any, that we
specifically set forth herein.

In rendering this opinion, we have assumed the genuineness and authenticity of
all signatures on original documents; the authenticity of all documents
submitted to us as originals; the conformity to originals of all documents
submitted to us as copies; the accuracy, completeness and authenticity of
certificates of public officials; and the due authorization, execution and
delivery of all documents (except the due authorization, execution and delivery
by the Company of the Purchase Agreement) where authorization, execution and
delivery are prerequisites to the effectiveness of such documents. We have also
assumed that all individuals executing and delivering documents in their
individual capacities had the legal capacity to so execute and deliver; that you
have received all documents you were to receive under the Purchase Agreement;
that the Purchase Agreement is an obligation binding upon you; that you have
filed any required California franchise or income tax 


<PAGE>   19
Page Two

returns and have paid any required California franchise or income taxes; and
that there are no extrinsic agreements or understandings among the parties to
the Purchase Agreement that would modify or interpret the terms of the Purchase
Agreement or the respective rights or obligations of the parties thereunder.

Our opinion is expressed only with respect to the federal laws of the United
States of America and the laws of the State of California. We express no opinion
as to whether the laws of any particular jurisdiction apply, and no opinion to
the extent that the laws of any jurisdiction other than those identified above
are applicable to the subject matter hereof. We are not rendering any opinion as
to compliance with any antifraud law, rule or regulation relating to securities,
or to the sale or issuance thereof.

With respect to the opinion in paragraph 3 hereof regarding issued and
outstanding capital stock of the Company, we have examined and have relied
solely on a certificate furnished by the Company's transfer agent, Bank of
Boston, a copy of which has been made available to you. We have undertaken no
independent verification with respect thereto.

With regard to our opinion in paragraph 4 below with respect to material
defaults under any of the Material Agreements (as defined below), we have relied
solely upon (i) inquiries of officers of the Company, (ii) a list supplied to us
by the Company of material agreements to which the Company is a party, or by
which it is bound (the "Material Agreements"), and (iii) an examination of the
items on the aforementioned list; we have made no further investigation.

On the basis of the foregoing, in reliance thereon and with the foregoing
qualifications, we are of the opinion that:

        1. The Company has been duly incorporated and is a validly existing
corporation in good standing under the laws of the State of California. The
Company has the requisite corporate power to own its property and assets and to
conduct its business as it is currently being conducted and, to the best of our
knowledge, is qualified as a foreign corporation to do business and is in good
standing in each jurisdiction in the United States in which the ownership of its
property or the conduct of its business requires such qualification and where
any statutory fines or penalties or any corporate disability imposed for the
failure to disqualify would materially and adversely affect the Company, its
assets, financial condition or operations.

        2. The Purchase Agreement has been duly and validly authorized, executed
and delivered by the Company and constitutes a legal, valid and binding
agreement of the Company enforceable against the Company in accordance with its
terms, except as enforcement may be limited by applicable bankruptcy,
insolvency, reorganization, arrangement with creditors, 


<PAGE>   20
Page Three

moratorium or other similar laws affecting creditors' rights, and subject to
general equity principles and to limitations on availability of equitable
relief, including specific performance.

        3. The Company's authorized capital stock consists of forty-five million
(45,000,000) shares of Common Stock, of which (excluding the Initial Shares to
be issued at Closing) ___________________________________________ (___________)
are issued and outstanding. The Initial Shares have been duly and validly
authorized, and upon issuance and delivery against payment therefor in
accordance with the Purchase Agreement will be validly issued, outstanding,
fully paid and nonassessable. To the best of our knowledge, there are no
options, warrants, conversion privileges, preemptive rights or other rights
outstanding to purchase any shares of the authorized but unissued capital stock
of the Company, other than rights granted under the Company's Equity Incentive
Plan, Non-Employee Directors Stock Option Plan and Employee Stock Purchase Plan,
for which the Company has reserved 2,355,000 shares of its Common Stock, a
warrant held by a lease financing entity to purchase 37,500 shares of Common
Stock, and the rights created in connection with the transactions contemplated
by the Purchase Agreement.

        4. The execution, delivery and performance of the Purchase Agreement by
the Company and the offer, issuance and sale of the Initial Shares pursuant
thereto (a) do not constitute a material default under the provisions of any of
the Material Agreements, (b) do not violate any provision of the Company's
Certificate of Incorporation or Bylaws, and (c) do not violate or contravene (i)
any governmental statute, rule or regulation applicable to the Company or (ii)
any order, writ, judgment, injunction, decree, determination or award which has
been entered against the Company and of which we are aware, the violation or
contravention of which would materially and adversely affect the Company, its
assets, financial condition or operations.

        5. To the best of our knowledge, there is no action, suit, proceeding or
investigation pending or overtly threatened against the Company before any
domestic or foreign court or administrative agency that questions the validity
of the Purchase Agreement or might result, either individually or in the
aggregate, in any material adverse change in the assets, financial condition or
operations of the Company.

        6. All consents, approvals, authorizations or orders of, and filings,
registrations and qualifications with any regulatory authority or governmental
body in the United States required for the consummation by the Company of the
offer, issuance and sale of the Initial Shares contemplated by the Purchase
Agreement have been made or obtained.

        7. The offer and sale of the Initial Shares is exempt from the
registration requirements of the Securities Act of 1933, as amended.

This opinion is intended solely for your benefit and is not to be made available
to or be relied upon by any other person, firm, or entity without our prior
written consent.

Very truly yours,

COOLEY GODWARD LLP
