                  NOTES TO THE UNAUDITED FINANCIAL STATEMENTS
                                 June 30, 1998

1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Organization and Basis of Presentation
Aradigm Corporation (the "Company") was incorporated in California in January
1991.  Since inception, Aradigm has been engaged in the development and
commercialization of non-invasive pulmonary drug delivery systems.  The Company
does not anticipate receiving significant revenue from the sale of products in
the upcoming year. Principal activities to date have included obtaining
financing, recruiting management and technical personnel, securing operating
facilities, conducting research and development, and expanding commercial
production capabilities.  These factors indicate that the Company's ability to
continue its research, development and commercialization activities is
dependent upon the ability of management to obtain additional financing as
required.

In the opinion of management, the financial statements reflect all adjustments,
which are of a normal recurring nature, necessary for a fair presentation.  The
accompanying financial statements should be read in conjunction with the
financial statements and notes thereto included with the Company's Annual
Report on Form 10-K.  The results of the Company's operations for the interim
periods presented are not necessarily indicative of operating results for the
full fiscal year or any future interim periods.

Use of Estimates
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions
that affect the amounts reported in the financial statements and accompanying
notes. Actual results could differ from those estimates.

Cash Equivalents and Investments
The Company considers all highly liquid investments purchased with an original
maturity of three months or less to be cash equivalents.  The Company places
its cash and cash equivalents in money market funds, commercial paper and
corporate master notes.  The Company's short-term investments consist of
corporate notes with maturities ranging from three to twelve months.

The Company classifies its investments as available-for-sale.
Available-for-sale investments are recorded at fair value with unrealized gains
and losses reported in the statement of shareholders' equity.  Fair values of
investments are based on quoted market prices, where available.  Realized gains
and losses, which have been immaterial to date, are included in interest and
other income and are derived using the specific identification method for
determining the cost of investments sold.  Dividend and interest income is
recognized when earned.

Depreciation and Amortization
The Company records property and equipment at cost and calculates depreciation
using the straight-line method over the estimated useful lives of the
respective assets, generally four to seven years. Machinery and equipment
acquired under capital leases is amortized over the useful lives of the assets.
Leasehold improvements are amortized over the shorter of the term of the lease
or useful life of the improvement.

Revenue Recognition
Contract revenues consist of revenue from collaboration agreements and
feasibility studies. The Company recognizes revenue ratably under the
agreements as costs are incurred. Deferred revenue represents the portion of
research payments received that has not been earned.  In accordance with
contract terms, up-front and milestone payments from collaborative research
agreements are considered

<PAGE>   8

reimbursements for costs incurred under the agreements and, accordingly, are
generally deferred when received and recognized as revenue based on actual
efforts expended over the remaining terms of the agreements.  Non-refundable
signing or license fee payments that are not dependent on future performance
under collaborative agreements are recognized as revenue when received.  Costs
of contract revenue approximate such revenue and are included in research and
development expenses.

Common Stock and Net Loss Per Share
Basic net loss per share has been computed using the weighted average number of
shares of common stock outstanding during the period.  At June 30, 1998 and
1997, outstanding stock options and other stock equivalents are not included as
their effect would be antidilutive.

In April 1998, the Company raised $12 million through a private sale of 1.1
million newly-issued shares of its common stock to a select group of
institutional investors.

Contingencies
In June of 1998, Eli Lilly and Company ("Lilly") filed a complaint against the
Company in the United States District Court for the Southern District of
Indiana.  The complaint made various allegations against the Company, arising
from the Company's decision to enter into an exclusive collaboration with Novo
Nordisk A/S, addressing the development and commercialization of a pulmonary
delivery system for insulin and insulin analogs.  The complaint seeks a
declaration that Lilly scientists are co-inventors of a patent application
filed by the Company relating to pulmonary delivery of an insulin analog or, in
the alternative, enforcement of an alleged agreement to grant Lilly an
nonexclusive license under such patent application.  The complaint also
contains certain other allegations and seeks unspecified damages and injunctive
relief. Management believes that Lilly's claims are without merit and that
this litigation will not have a material adverse effect on the Company's
results of operations, cash flows or financial position.  The Company recently
filed an answer denying all material allegations of the complaint.

Recent Accounting Pronouncements
In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 130 ("SFAS 130"), "Reporting Comprehensive
Income," and Statement of Financial Accounting Standards No. 131 ("SFAS 131"),
"Disclosures about Segments of an Enterprise and Related Information," which
require additional disclosures to be adopted beginning in the first quarter of
1998 and on December 31, 1998, respectively.

Under SFAS 130, the Company is required to display comprehensive income and its
components as part of the Company's full set of financial statements.
Comprehensive income is comprised of net income and other comprehensive income.
The measurement and presentation of net income will not change.  Other
comprehensive income includes certain changes in equity of the Company that are
excluded from net income.  Specifically, SFAS 130 requires unrealized holding
gains and losses on the Company's available-for-sale securities, which are
currently reported separately in shareholders' equity, to be included in other
comprehensive income.  During the first two quarters of 1998 and 1997, total
comprehensive income did not differ materially from net income reported for
those periods.

SFAS 131 requires that the Company report financial and descriptive information
about its reportable operating segments.  The Company is evaluating the impact,
if any, of SFAS 131 on its financial statement disclosures, but does not
believe the additional disclosure will be material to the financial statements.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS

         The discussion below contains forward-looking statements that are
based on the beliefs of the Company's management, as well as assumptions made
by, and information currently available to, the Company's management.  The
Company's future results, performance or achievements could differ materially
from those expressed in, or implied by, any such forward-looking statements as
a result of certain factors, including, but not limited to, those discussed in
this section as well as in the section entitled "Risk Factors" and elsewhere in
the Company's Form 10-K filed with the Securities and Exchange Commission on
March 24, 1998.

         The Company's business is subject to significant risks including, but
not limited to, the success of its research and development efforts, its
dependence on corporate partners for marketing and distribution resources,
obtaining and enforcing patents important to the Company's business, clearing
the lengthy and expensive regulatory process and possible competition from
other products. Even if the Company's products appear promising at various
stages of development they may not reach the market or may not be commercially
successful for a number of reasons. Such reasons include, but are not limited
to, the possibilities that the potential products will be found to be
ineffective during clinical trials, fail to receive necessary regulatory
approvals, be difficult to manufacture on a large scale, be uneconomical to
market, be precluded from commercialization by proprietary rights of third
parties or may not gain acceptance from health care professionals and patients.
Readers are cautioned not to place undue reliance on the forward-looking
statements contained herein.  The Company undertakes no obligation to publicly
release the results of any revision to these forward-looking statements which
may be made to reflect events or circumstances occurring after the date hereof
or to reflect the occurrence of unanticipated events.

OVERVIEW

         Since its inception in 1991, Aradigm has been engaged in the
development of pulmonary drug delivery systems. As of June 30, 1998, the
Company had an accumulated deficit of $43.5 million. The Company has been
unprofitable since inception and expects to incur additional operating losses
over at least the next several years as the Company's research and development
efforts, preclinical and clinical testing activities and manufacturing scale-up
efforts expand and as the Company plans and builds its late-stage clinical and
early commercial production capabilities.  To date, Aradigm has not sold any
products and does not anticipate receiving significant revenue from product
sales in 1998.  The sources of working capital have been equity financing,
financing of equipment acquisitions, interest earned on investments of cash and
revenues from research and feasibility agreements and development contracts.

         The Company has performed and has been compensated for expenses
incurred during initial feasibility work and for work performed under
collaborative agreements. Once feasibility is demonstrated, the Company's
strategy is to enter into development contracts with pharmaceutical corporate
partners. The Company anticipates that these partners will pay for research and
development expenses and will make additional payments to the Company as it
achieves certain significant milestones. The Company also expects to receive
royalties from its corporate partners based on revenues from product sales and
to receive revenue from the manufacturing of unit dose packets and hand-held
devices.  However, there can be no assurance that the Company will be able to
generate sufficient product or contract research revenue to become profitable
or to sustain profitability.

RESULTS OF OPERATIONS

         Three and Six Months Ended June 30, 1998 and 1997

         Contract Revenue.  Contract revenue for the three-month period ended
June 30, 1998 increased to $4.1 million from $170,000 for the same period in
1997. Contract revenue for the six-month period ended June 30, 1998 increased
to $6.8 million from $740,000 for the same period in 1997.  These increases in
revenue were due primarily to increased partner-funded product development
activities.  The Company is developing pulmonary delivery systems with
SmithKline Beecham, plc, to manage acute and breakthrough pain using narcotic
analgesics, and Novo Nordisk A/S, to manage diabetes using insulin and other
blood glucose regulating compounds.  Costs of contract research revenue
approximate such revenue and are included in research and development expense.

         Research and Development Expenses.  Research and development expenses
for the three-month period ended June 30, 1998 increased to $5.6 million from
$3.3 million for the same period in 1997. Research and development expenses for
the six-month period ended June 30, 1998 increased to $10.0 million from $5.8
million for the same period in 1997.  These increases were attributable
primarily to the hiring of additional scientific personnel and expenses
associated with the expansion of research and development efforts on the AERx
system. These expenses represent proprietary research expenses as well as the
costs related to contract research revenue and include salaries and benefits of
scientific and development personnel, laboratory supplies, consulting services
and the expenses associated with the development of manufacturing processes.
The Company expects research and development spending to increase significantly
over the next few years as the Company continues to expand its development
activities under collaborative agreements and plans, builds and scales up a
late-stage clinical and early-stage commercial manufacturing facility.  The
increase in research and development expenditures cannot be predicted
accurately as it depends in part upon future success in obtaining new
collaborative agreements.

         General and Administrative Expenses.  General and administrative
expenses for the three-month period ended June 30, 1998 increased to $2.7
million from $1.5 million for the same period in 1997. General and
administrative expenses for the six-month period ended June 30, 1998 increased
to $5.0 million from $2.4 million for the same period in 1997.  These increases
were attributable primarily to support of the Company's increased research
efforts, additional facilities expense, administrative staffing, business
development and marketing activities.  The Company expects to incur greater
general and administrative expenses in the future as it expands its research,
development and manufacturing activities and increases its efforts to develop
collaborative relationships with corporate partners.

         Interest Income.  Interest income for the three-month period ended
June 30, 1998 increased to $493,000 from $342,000 for the same period in 1997.
Interest income for the six-month period ended June 30, 1998 increased to
$811,000 from $724,000 for the same period in 1997.  These increases were due
to the Company maintaining larger cash and investment balances. The higher cash
and investment balances are a result of the Company's receipt of research
funding and milestone payments from collaborative partners, the completion of a
private placement of the Company's Common Stock in April 1998 which raised net
proceeds of $12.0 million, and Novo Nordisk A/S making a $5.0 million equity
investment in Aradigm at a 25% premium-to-market price in conjunction with the
June 1998 development agreement between the Company and Novo Nordisk A/S to
develop insulin products using Aradigm's non-invasive pulmonary drug delivery
system.


         Interest Expense.  Interest expense for the three-month period ended
June 30, 1998 increased to $127,000 from $22,000 for the same period in 1997.
Interest expense for the six-month period ended June 30, 1998 increased to
$217,000 from $36,000 for the same period in 1997.  These increases are a
result of higher outstanding capital lease and equipment loan balances under
the Company's equipment lines of credit.
<PAGE>   11
LIQUIDITY AND CAPITAL RESOURCES

         The Company has financed its operations since inception primarily
through private placements and public offerings of its capital stock, proceeds
from financings of equipment acquisitions, contract research revenue and
interest earned on investments. As of June 30, 1998, the Company had received
approximately $72.3 million in net proceeds from sales of its capital stock.
The Company also has a $5.0 million equipment line of credit, of which
approximately $438,000 remains available for purchases through September 1998.
As of June 30, 1998, the Company had cash, cash equivalents and investments of
approximately $40.0 million.  The Company also has the right to sell $5 million
of common stock to each of SmithKline Beecham, plc, and Novo Nordisk A/S.

         Net cash provided by operating activities in the six months ended June
30, 1998 was $1.1 million compared to net cash used of $6.8 million in the same
period in 1997.  The increase resulted primarily from increases in deferred
revenue, accounts payable, accrued liabilities and receivables offset partially
by an increase in net loss of $800,000.

         Net cash used in investing activities in the six months ended June 30,
1998 was $10.5 million compared to net cash provided of $1.6 million in the
same period in 1997.  The decrease resulted primarily from the Company's
expenditures made for capital equipment and decreased receipts of net proceeds
from investment maturities.

         Net cash provided by financing activities in the six months ended June
30, 1998 of $19.6 million resulted primarily from the Company's receipt of
proceeds from the issuance of common stock and net receipt of proceeds from
equipment loans.  Net cash used in financing activities in the six months ended
June 30, 1997 of $96,000 resulted primarily from the Company's repayment of
capital lease obligations.

         The development of the Company's technology and proposed products will
require a commitment of substantial funds to conduct the costly and
time-consuming research and preclinical and clinical testing activities
necessary to develop and refine such technology and proposed products and to
bring any such products to market.  The Company's future capital requirements
will depend on many factors, including continued progress in the research and
development of the Company's technology and drug delivery systems, the ability
of the Company to establish and maintain favorable collaborative arrangements
with others, progress with preclinical studies and clinical trials, the time
and costs involved in obtaining regulatory approvals, the cost of development
and the rate of scale-up of the Company's production technologies, the cost
involved in preparing, filing, prosecuting, maintaining and enforcing patent
claims and the need to acquire licenses or other rights to new technology.

         The Company expects its cash requirements to increase due to expected
increases in expenses related to the further research and development of its
technologies resulting from a larger number of collaborative partnerships,
process development for the manufacture of AERx systems, and general and
administrative costs.  These expenses include, but are not limited to,
increases in personnel and personnel-related costs, purchases of capital
equipment, construction of prototype devices and facilities expansion including
the planning and building of a late-stage clinical and early-stage commercial
manufacturing facility.

         The Company expects that its existing capital resources, committed
funding from its existing corporate partnership with SmithKline Beecham and
Novo Nordisk AS and projected interest income will enable the Company to
maintain current and planned operations through at least 1999.  However, there
can be no assurance that the Company will not need to raise substantial
additional capital to fund its operations prior to such time.  There can be no
assurance that additional financing will be available on acceptable terms or at
all.  The Company's cash requirements, however, may vary materially from those
now planned because of results of research and development efforts, including
capital expenditures and funding preclinical and clinical trials and
manufacturing capacity for preclinical, clinical and full scale

manufacturing requirements of the AERx system. The Company may seek additional
funding through collaborations or through public or private equity or debt
financings. However, there cannot be any assurance that additional financing
can be obtained on acceptable terms, or at all. If additional funds are raised
by issuing equity securities, dilution to shareholders may result. If adequate
funds are not available, the Company may be required to delay, to reduce the
scope of, or to eliminate one or more of its research and development programs,
or to obtain funds through arrangements with collaborative partners or other
sources that may require the Company to relinquish rights to certain of its
technologies or products that the Company would not otherwise relinquish.

PART II.         OTHER INFORMATION

ITEM 1.    LEGAL PROCEEDINGS

                 In June of 1998, Eli Lilly and Company ("Lilly") filed a
           complaint against the Company in the United States District Court
           for the Southern District of Indiana.  The complaint made various
           allegations against the Company, arising from the Company's decision
           to enter into an exclusive collaboration with Novo Nordisk A/S,
           addressing the development and commercialization of a pulmonary
           delivery system for insulin and insulin analogs.  Management
           believes that Lilly's claims are without merit and that this
           litigation will not have a material adverse effect on the results of
           operations, cash flows or financial position.  The Company has
           sponsored various studies of the pulmonary delivery of insulin and
           insulin analogs using materials supplied by Lilly under a series of
           agreements dating from January of 1996.  The Company and Lilly had
           also conducted negotiations concerning a long-term supply agreement
           under which Lilly would supply bulk insulin to the Company for
           commercialization in the Company's AERx Diabetes Management System,
           and a separate agreement under which the Company would license
           certain intellectual property to Lilly.  These negotiations were
           terminated after the Company proceeded with its agreement with Novo
           Nordisk A/S.  The complaint seeks a declaration that Lilly
           scientists are co-inventors of a patent application filed by the
           Company relating to pulmonary delivery of an insulin analog or, in
           the alternative, enforcement of an alleged agreement to grant Lilly
           an nonexclusive license under such patent application.  The
           complaint also contains allegations of misappropriation of trade
           secrets, breach of fiduciary duty, conversion and unjust enrichment
           and seeks unspecified damages and injunctive relief.  The Company
           recently filed an answer denying all material allegations of the
           complaint.

     SECTION 4.  PLACE OF MEETINGS.  Meetings of shareholders shall be held at
the principal executive office of the corporation, or at any other place,
within or outside the State of California, which may be fixed either by the
Board of Directors or by the written consent of all persons entitled to vote at
such meeting, given either before or after the meeting and filed with the
Secretary of the Corporation.

     SECTION 5.  ANNUAL MEETING.

          (a)    The annual meeting of the shareholders of the corporation, for
the purpose of election of directors and for such other business as may
lawfully come before it, shall be held on such date and at such time as may be
designated from time to time by the Board of Directors.



                                       1

          (b)    At an annual meeting of the shareholders, only such business
shall be conducted as shall have been properly brought before the meeting.  To
be properly brought before an annual meeting, business must be:  (A) specified
in the notice of meeting (or any supplement thereto) given by or at the
direction of the Board of Directors, (B) otherwise properly brought before the
meeting by or at the direction of the Board of Directors, or (C) otherwise
properly brought before the meeting by a share-holder.  For business to be
properly brought before an annual meeting by a shareholder, the shareholder
must have given timely notice thereof in writing to the Secretary of the
corporation.  To be timely, a shareholder's notice must be delivered to or
mailed and received at the principal executive offices of the corporation not
later than the close of business on the sixtieth (60th) day nor earlier than
the close of business on the ninetieth (90th) day prior to the first
anniversary of the preceding year's annual meeting; provided, however, that in
the event that no annual meeting was held in the previous year or the date of
the annual meeting has been changed by more than thirty (30) days from the date
contemplated at the time of the previous year's proxy statement, notice by the
shareholder to be timely must be so received not earlier than the close of
business on the ninetieth (90th) day prior to such annual meeting and not later
than the close of business on the later of the sixtieth (60th) day prior to
such annual meeting or, in the event public announcement of the date of such
annual meeting is first made by the corporation fewer than seventy (70) days
prior to the date of such annual meeting, the close of business on the tenth
(10th) day following the day on which public announcement of the date of such
meeting is first made by the corporation. A shareholder's notice to the
Secretary shall set forth as to each matter the shareholder proposes to bring
before the annual meeting:  (i) a brief description of the business desired to
be brought before the annual meeting and the reasons for conducting such
business at the annual meeting, (ii) the name and address, as they appear on
the corporation's books, of the share-holder proposing such business, (iii) the
class and number of shares of the corporation which are beneficially owned by
the shareholder, (iv) any material interest of the shareholder in such business
and (v) any other information that is required to be provided by the
shareholder pursuant to Regulation 14A under the Securities Exchange Act of
1934, as amended (the "1934 Act"), in his capacity as a proponent to a
shareholder proposal.  Notwithstanding the foregoing, in order to include
information with respect to a shareholder proposal in the proxy statement and
form of proxy for a shareholder's meeting, shareholders must provide notice as
required by the regulations promulgated under the 1934 Act.  Notwithstanding
anything in these Bylaws to the contrary, no business shall be conducted at any
annual meeting except in accordance with the procedures set forth in this
paragraph (b).  The chairman of the annual meeting shall, if the facts warrant,
determine and declare at the meeting that business was not properly brought
before the meeting and in accordance with the provisions of this paragraph (b),
and, if he should so determine, he shall so declare at the meeting that any
such business not properly brought before the meeting shall not be transacted.

          (c)    Only persons who are nominated in accordance with the
procedures set forth in this paragraph (c) shall be eligible for election as
directors.  Nominations of persons for election to the Board of Directors of
the corporation may be made at a meeting of shareholders by or at the direction
of the Board of Directors or by any shareholder of the corporation entitled to
vote in the election of directors at the meeting who complies with the notice
procedures set forth in this paragraph (c).  Such nominations, other than those
made by or at the direction of the Board of Directors, shall be made pursuant
to timely notice in writing to the Secretary of the corporation in accordance
with the provisions of paragraph (b) of this Section 5.  Such share-





                                       2
<PAGE>   8



holder's notice shall set forth (i) as to each person, if any, whom the
shareholder proposes to nominate for election or re-election as a director:
(A) the name, age, business address and residence address of such person, (B)
the principal occupation or employment of such person, (C) the class and number
of shares of the corporation which are beneficially owned by such person, (D) a
description of all arrangements or understandings between the shareholder and
each nominee and any other person or persons (naming such person or persons)
pursuant to which the nominations are to be made by the shareholder, and (E)
any other information relating to such person that is required to be disclosed
in solicitations of proxies for election of directors, or is otherwise
required, in each case pursuant to Regulation 14A under the 1934 Act (including
without limitation such person's written consent to being named in the proxy
statement, if any, as a nominee and to serving as a director if elected); and
(ii) as to such shareholder giving notice, the information required to be
provided pursuant to paragraph (b) of this Section 5.  At the request of the
Board of Directors, any person nominated by a shareholder for election as a
director shall furnish to the Secretary of the corporation that information
required to be set forth in the shareholder's notice of nomination which
pertains to the nominee.  No person shall be eligible for election as a
director of the corporation unless nominated in accordance with the procedures
set forth in this paragraph (c).  The chairman of the meeting shall, if the
facts warrant, determine and declare at the meeting that a nomination was not
made in accordance with the procedures prescribed by these Bylaws, and if he
should so determine, he shall so declare at the meeting, and the defective
nomination shall be disregarded.

          (d)    For purposes of this Section 5, "public announcement" shall
mean disclosure in a press release reported by the Dow Jones News Service,
Associated Press or comparable national news service or in a document publicly
filed by the corporation with the Securities and Exchange Commission pursuant
to Section 13, 14 or 15(d) of the Exchange Act.

     SECTION 6.  POSTPONEMENT OF ANNUAL MEETING.  The Board of Directors and
the President shall each have authority to hold at an earlier date and/or time,
or to postpone to a later date and/or time, the annual meeting of shareholders.

     SECTION 7.  SPECIAL MEETINGS.

          (a)    Special meetings of the shareholders, for any purpose or
purposes, may be called by the Board of Directors, the Chairman of the Board of
Directors, the President, or the holders of shares entitled to cast not less
than ten percent (10%) of the votes at the meeting.

          (b)    Upon written request to the Chairman of the Board of
Directors, the President, any vice president or the Secretary of the
corporation by any person or persons (other than the Board of Directors)
entitled to call a special meeting of the share-holders, such officer forthwith
shall cause notice to be given to the shareholders entitled to vote, that a
meeting will be held at a time requested by the person or persons calling the
meeting, such time to be not less than thirty-five (35) nor more than sixty
(60) days after receipt of such request.  If such notice is not given within
twenty (20) days after receipt of such request, the person or persons calling
the meeting may give notice thereof in the manner provided by law or in these
bylaws. Nothing contained in this Section 7 shall be construed as limiting,
fixing or affecting the time or date when a meeting of share-holders called by
action of the Board of Directors may be held.





                                       3

     SECTION 8.  NOTICE OF MEETINGS.  Except as otherwise may be required by
law and subject to subsection 7(b) above, written notice of each meeting of
shareholders shall be given to each shareholder entitled to vote at that
meeting (see Section 15 below), by the Secretary, assistant secretary or other
person charged with that duty, not less than ten (10) (or, if sent by third
class mail, thirty (30)) nor more than sixty (60) days before such meeting.

         Notice of any meeting of shareholders shall state the date, place and
hour of the meeting and,

          (a)    in the case of a special meeting, the general nature of the
business to be transacted, and no other business may be transacted at such
meeting;

          (b)    in the case of an annual meeting, the general nature of
matters which the Board of Directors, at the time the notice is given, intends
to present for action by the shareholders;

          (c)    in the case of any meeting at which directors are to be
elected, the names of the nominees intended at the time of the notice to be
presented by management for election; and

          (d)    in the case of any meeting, if action is to be taken on any of
the following proposals, the general nature of such proposal:

               (1)   a proposal to approve a transaction within the provisions
of California Corporations Code, Section 310 (relating to certain transactions
in which a director has an interest);

               (2)   a proposal to approve a transaction within the provisions
of California Corporations Code, Section 902 (relating to amending the Articles
of Incorporation of the corporation);

               (3)   a proposal to approve a transaction within the provisions
of California Corporations Code, Sections 181 and 1201 (relating to
reorganization);

               (4)   a proposal to approve a transaction within the provisions
of California Corporations Code, Section 1900 (winding up and dissolution);

               (5)   a proposal to approve a plan of distribution within the
provisions of California Corporations Code, Section 2007 (relating to certain
plans providing for distribution not in accordance with the liquidation rights
of preferred shares, if any).

                 At a special meeting, notice of which has been given in
accordance with this Section, action may not be taken with respect to business,
the general nature of which has not been stated in such notice.  At an annual
meeting, action may be taken with respect to business stated in the notice of
such meeting, given in accordance with this Section, and, subject to
sub-section 8(d) above, with respect to any other business as may properly come
before the meeting.

     SECTION 9.  MANNER OF GIVING NOTICE.  Notice of any meeting of
shareholders shall be given either personally or by first-class mail, or, if
the corporation has outstanding shares held of record by 500 or more persons
(determined as provided in California Corporations Code Section





                                       4
<PAGE>   10



605) on the record date for such meeting, third-class mail, or telegraphic or
other written communication, addressed to the shareholder at the address of
that shareholder appearing on the books of the corporation or given by the
shareholder to the corporation for the purpose of notice.  If no such address
appears on the corporation's books or is given, notice shall be deemed to have
been given if sent to that shareholder by first-class mail or telegraphic or
other written communication to the corporation's principal executive office, or
if published at least once in a newspaper of general circulation in the county
where that office is located.  Notice shall be deemed to have been given at the
time when delivered personally or deposited in the mail or sent by telegram or
other means of written communication.

    If any notice addressed to a shareholder at the address of that shareholder
appearing on the books of the corporation is returned to the corporation by the
United States Postal Service marked to indicate that the United States Postal
Service is unable to deliver the notice to the shareholder at that address, all
future notices shall be deemed to have been duly given without further mailing
if these shall be available to the shareholder on written demand by the
shareholder at the principal executive office of the corporation for a period
of one year from the date of the giving of the notice.

     SECTION 10.     QUORUM AND TRANSACTION OF BUSINESS.

          (a)    At any meeting of the shareholders, a majority of the shares
entitled to vote, represented in person or by proxy, shall constitute a quorum.
If a quorum is present, the affirmative vote of the majority of shares
represented at the meeting and voting (which shares voting affirmatively also
constitute at least a majority of the required quorum) on any matter shall be
the act of the shareholders, unless the vote of a greater number or voting by
classes is required by law or by the Articles of Incorporation, and except as
provided in subsection (b) below.

          (b)    The shareholders present at a duly called or held meeting of
the shareholders at which a quorum is present may continue to do business until
adjournment, notwithstanding the withdrawal of enough shareholders to leave
less than a quorum, provided that any action taken (other than adjournment) is
approved by at least a majority of the shares required to constitute a quorum.

          (c)    In the absence of a quorum, no business other than adjournment
may be transacted, except as described in sub-section (b) above.

     SECTION 11.     ADJOURNMENT AND NOTICE OF ADJOURNED MEETINGS.  Any
meeting of shareholders may be adjourned from time to time, whether or not a
quorum is present, by the affirmative vote of a majority of shares represented
at such meeting either in person or by proxy and entitled to vote at such
meeting.

    In the event any meeting is adjourned, it shall not be necessary to give
notice of the time and place of such adjourned meeting pursuant to Sections 8
and 9 of these bylaws; provided that if any of the following three events
occur, such notice must be given:

          (a)    announcement of the adjourned meeting's time and place is not
made at the original meeting which it continues or

          (b)    such meeting is adjourned for more than forty- five (45) days
from the date set for the original meeting or





                                       5
<PAGE>   11

          (c)    a new record date is fixed for the adjourned meeting.

    At the adjourned meeting, the corporation may transact any business which
might have been transacted at the original meeting.

     SECTION 12.     WAIVER OF NOTICE, CONSENT TO MEETING OR APPROVAL OF
MINUTES.

          (a)    Subject to subsection (b) of this Section, the transactions of
any meeting of shareholders, however called and noticed, and wherever held,
shall be as valid as though made at a meeting duly held after regular call and
notice, if a quorum is present either in person or by proxy, and if, either
before or after the meeting, each of the persons entitled to vote but not
present in person or by proxy signs a written waiver of notice or a consent to
holding of the meeting or an approval of the minutes thereof.

          (b)    A waiver of notice, consent to the holding of a meeting or
approval of the minutes thereof need not specify the business to be transacted
or transacted at nor the purpose of the meeting; provided that in the case of
proposals described in subsection (d) of Section 8 of these bylaws, the general
nature of such proposals must be described in any such waiver of notice and
such proposals can only be approved by waiver of notice, not by consent to
holding of the meeting or approval of the minutes.

          (c)    All waivers, consents and approvals shall be filed with the
corporate records or made a part of the minutes of the meeting.

          (d)    A person's attendance at a meeting shall constitute waiver of
notice of and presence at such meeting, except when such person objects at the
beginning of the meeting to transaction of any business because the meeting is
not lawfully called or convened and except that attendance at a meeting is not
a waiver of any right to object to the consideration of matters which are
required by law or these bylaws to be in such notice (including those matters
described in subsection (d) of Section 8 of these bylaws), but are not so
included if such person expressly objects to consideration of such matter or
matters at any time during the meeting.

     SECTION 13.     NO ACTION BY WRITTEN CONSENT WITHOUT A MEETING.  No action
of the shareholders may be taken without a meeting or without prior notice.

     SECTION 14.     VOTING.  Voting at any meeting of shareholders need not be
by ballot; provided, however, that elections for directors must be by ballot if
balloting is demanded by a shareholder at the meeting and before the voting
begins.

    Until such time as this corporation becomes a listed corporation within the
meaning of Section 301.5 of the California Corporations Code, every person
entitled to vote at an election for directors may cumulate the votes to which
such person is entitled, i.e., such person may cast a total number of votes
equal to the number of directors to be elected multiplied by the number of
votes to which such person's shares are entitled, and may cast said total
number of votes for one or more candidates in such proportions as such person
thinks fit; provided, however, no shareholder shall be entitled to so cumulate
such shareholder's votes unless the candidates for which such shareholder is
voting have been placed in nomination prior to the voting and a shareholder has
given notice at the meeting, prior to the vote, of an intention to cumulate
votes.  In any election of directors, the candidates receiving the highest
number of votes, up to the number of directors to be elected, are elected.





                                       6
<PAGE>   12

    Except as may be otherwise provided in the Articles of Incorporation or by
law, and subject to the foregoing provisions regarding the cumulation of votes,
each shareholder shall be entitled to one vote for each share held; provided,
however, that the right to cumulative voting provided for above shall be
eliminated at such time as this corporation becomes a listed corporation within
the meaning of Section 301.5 of the California Corporation Code.

    Any shareholder may vote part of such shareholder's shares in favor of a
proposal and refrain from voting the remaining shares or vote them against the
proposal, other than elections to office, but, if the shareholder fails to
specify the number of shares such shareholder is voting affirmatively, it will
be conclusively presumed that the shareholder's approving vote is with respect
to all shares such shareholder is entitled to vote.

    No shareholder approval, other than unanimous approval of those entitled to
vote, will be valid as to proposals described in subsection 8(d) of these
bylaws unless the general nature of such business was stated in the notice of
meeting or in any written waiver of notice.

     SECTION 15.     PERSONS ENTITLED TO VOTE OR CONSENT.  The Board of
Directors may fix a record date pursuant to Section 60 of these bylaws to
determine which shareholders are entitled to notice of and to vote at a meeting
as provided in Section 14 of these bylaws.  Only persons in whose name shares
otherwise entitled to vote stand on the stock records of the corporation on
such date shall be entitled to vote or consent.

    If no record date is fixed:

          (a)    The record date for determining shareholders entitled to
notice of or to vote at a meeting of shareholders shall be at the close of
business on the business day next preceding the day notice is given or, if
notice is waived, at the close of business on the business day next preceding
the day on which the meeting is held; and

          (b)    The record date for determining shareholders for any other
purpose shall be at the close of business on the day on which the Board of
Directors adopts the resolution relating thereto, or the sixtieth (60th) day
prior to the date of such other action, whichever is later.

    A determination of shareholders of record entitled to notice of or to vote
at a meeting of shareholders shall apply to any adjournment of the meeting
unless the Board of Directors fixes a new record date for the adjourned
meeting; provided, however, that the Board of Directors shall fix a new record
date if the meeting is adjourned for more than forty-five (45) days from the
date set for the original meeting.

    Shares of the corporation held by its subsidiary or subsidiaries (as
defined in California Corporations Code, Section 189(b)) are not entitled to
vote in any matter.

     SECTION 16.     PROXIES.  Every person entitled to vote may do so either
in person or by one or more agents authorized to act by a written proxy
executed by the person or such person's duly authorized agent and filed with
the Secretary of the corporation; provided that no such proxy shall be valid
after the expiration of eleven (11) months from the date of its execution
unless otherwise provided in the proxy.  The manner of execution, suspension,
revocation, exercise and effect of proxies is governed by law.

     SECTION 17.     INSPECTORS OF ELECTION.  Before any meeting of
shareholders, the Board of Directors may appoint any persons, other than
nominees for office, to act as inspectors of election at the meeting or its
adjournment. If no inspectors of election are so appointed, the





                                       7
<PAGE>   13



chairman of the meeting may, and on the request of any shareholder or a
shareholder's proxy shall, appoint inspectors of election at the meeting.  The
number of inspectors shall be either one (1) or three (3).  If inspectors are
appointed at a meeting on the request of one or more shareholders or proxies,
the majority of shares represented in person or proxy shall determine whether
one (1) or three (3) inspectors are to be appointed.  If any person appointed
as inspector fails to appear or fails or refuses to act, the chairman of the
meeting may, and upon the request of any shareholder or a shareholder's proxy
shall, appoint a person to fill that vacancy.

    These inspectors shall:

          (a)    Determine the number of shares outstanding and the voting
power of each, the shares represented at the meeting, the existence of a
quorum, and the authenticity, validity, and effect of proxies;

          (b)    Receive votes or ballots;

          (c)    Hear and determine all challenges and questions in any way
arising in connection with the right to vote;

          (d)    Count and tabulate all votes or ballots;

          (e)    Determine when the polls shall close;

          (f)    Determine the result; and

          (g)    Do any other acts that may be proper to conduct the election
or vote with fairness to all shareholders.

                                   ARTICLE IV

                               BOARD OF DIRECTORS

     SECTION 18.     POWERS.  Subject to the provisions of law or any
limitations in the Articles of Incorporation or these bylaws, as to action
required to be approved by the shareholders or by the outstanding shares, the
business and affairs of the corporation shall be managed and all corporate
powers shall be exercised, by or under the direction of the Board of Directors.
The Board of Directors may delegate the management of the day-to-day operation
of the business of the corporation to a management company or other person,
provided that the business and affairs of the corporation shall be managed and
all corporate powers shall be exercised under the ultimate direction of the
Board of Directors.

     SECTION 19.     NUMBER OF DIRECTORS.  The authorized number of directors
of the corporation shall be not less than a minimum of five (5) nor more than a
maximum of nine (9) (which maximum number in no case shall be greater than two
times said minimum, minus one) and the number of directors presently authorized
is eight (8).  The exact number of directors shall be set within these limits
from time to time (a) by approval of the Board of Directors, or (b) by the
affirmative vote of a majority of the shares represented and voting at a duly
held meeting at which a quorum is present (which shares voting affirmatively
also constitute at least a majority





                                       8
<PAGE>   14

of the required quorum) or by the written consent of shareholders pursuant to
Section 13 hereinabove.

    Any amendment of these bylaws changing the maximum or minimum number of
directors may be adopted only by the affirmative vote of a majority of the
outstanding shares entitled to vote; provided, an amendment reducing the
minimum number of directors to less than five (5), cannot be adopted if votes
cast against its adoption at a meeting are equal to more than 16-2/3 percent of
the outstanding shares entitled to vote.

    No reduction of the authorized number of directors shall remove any
director prior to the expiration of such director's term of office.

     SECTION 20.     ELECTION OF DIRECTORS, TERM, QUALIFICATIONS.  The
directors shall be elected at each annual meeting of shareholders to hold
office until the next annual meeting.  Each director, including a director
elected or appointed to fill a vacancy, shall hold office either until the
expiration of the term for which elected or appointed and until a successor has
been elected and qualified, or until his death, resignation or removal.
Directors need not be shareholders of the corporation.

     SECTION 21.     RESIGNATIONS.  Any director of the corporation may resign
effective upon giving written notice to the Chairman of the Board, the
President, the Secretary or the Board of Directors of the corporation, unless
the notice specifies a later time for the effectiveness of such resignation.
If the resignation specifies effectiveness at a future time, a successor may be
elected pursuant to Section 23 of these bylaws to take office on the date that
the resignation becomes effective.

     SECTION 22.     REMOVAL.  The Board of Directors may declare vacant the
office of a director who has been declared of unsound mind by an order of court
or who has been convicted of a felony.

    The entire Board of Directors or any individual director may be removed
from office without cause by the affirmative vote of the holders of a majority
of the outstanding shares entitled to vote on such removal; provided, however,
that unless the entire Board is removed, no individual director may be removed
when the votes cast against such director's removal would be sufficient to
elect that director if voted cumulatively at an election at which the same
total number of votes cast were cast and the entire number of directors
authorized at the time of such director's most recent election were then being
elected.

     SECTION 23.     VACANCIES.  A vacancy or vacancies on the Board of
Directors shall be deemed to exist in case of the death, resignation or removal
of any director, or upon increase in the authorized number of directors or if
shareholders fail to elect the full authorized number of directors at an annual
meeting of shareholders or if, for whatever reason, there are fewer directors
on the Board of Directors, than the full number authorized.  Such vacancy or
vacancies may be filled by a majority of the remaining directors, though less
than a quorum, or by a sole remaining director.  The shareholders may elect a
director at any time to fill any vacancy not filled by the directors.

    If, after the filling of any vacancy by the directors, the directors then
in office who have been elected by the share-holders constitute less than a
majority of the directors then in office, any holder or holders of an aggregate
of five percent (5%) or more of the shares outstanding at that time and having
the right to vote for such directors may call a special meeting of shareholders
to be held to elect the entire Board of Directors.  The term of office of any
director shall terminate upon such election of a successor.

<PAGE>   15

     SECTION 24.     REGULAR MEETINGS.  Regular meetings of the Board of
Directors shall be held at such times, places and dates as fixed in these
bylaws or by the Board of Directors; provided, however, that if the date for
such a meeting falls on a legal holiday, then the meeting shall be held at the
same time on the next succeeding full business day.  Regular meetings of the
Board of Directors held pursuant to this Section 24 may be held without notice.

     SECTION 25.     PARTICIPATION BY TELEPHONE.  Members of the Board of
Directors may participate in a meeting through use of conference telephone or
similar communications equipment, so long as all members participating in such
meeting can hear one another.  Such participation constitutes presence in
person at such meeting.

     SECTION 26.     SPECIAL MEETINGS.  Special meetings of the Board of
Directors for any purpose may be called by the Chairman of the Board or the
President or any vice president or the Secretary of the corporation or any two
(2) directors.

     SECTION 27.     NOTICE OF MEETINGS.  Notice of the date, time and place of
all meetings of the Board of Directors, other than regular meetings held
pursuant to Section 24 above shall be delivered personally, orally or in
writing, or by telephone or telegraph to each director, at least forty-eight
(48) hours before the meeting, or sent in writing to each director by
first-class mail, charges prepaid, at least four (4) days before the meeting.
Such notice may be given by the Secretary of the corporation or by the person
or persons who called a meeting.  Such notice need not specify the purpose of
the meeting.  Notice of any meeting of the Board of Directors need not be given
to any director who signs a waiver of notice of such meeting, or a consent to
holding the meeting or an approval of the minutes thereof, either before or
after the meeting, or who attends the meeting without protesting prior thereto
or at its commencement such director's lack of notice.  All such waivers,
consents and approvals shall be filed with the corporate records or made a part
of the minutes of the meeting.

     SECTION 28.     PLACE OF MEETINGS.  Meetings of the Board of Directors may

     SECTION 29.     ACTION BY WRITTEN CONSENT WITHOUT A MEETING.  Any action
required or permitted to be taken by the Board of Directors may be taken
without a meeting, if all members of the Board of Directors individually or
collectively consent in writing to such action.  Such written consent or
consents shall be filed with the minutes of the proceedings of the Board of
Directors.  Such action by written consent shall have the same force and effect
as a unanimous vote of such directors.

     SECTION 30.     QUORUM AND TRANSACTION OF BUSINESS.  A majority of the
authorized number of directors shall constitute a quorum for the transaction of
business.  Every act or decision done or made by a majority of the authorized
number of directors present at a meeting duly held at which a quorum is present
shall be the act of the Board of Directors, unless the law, the Articles of
Incorporation or these bylaws specifically require a greater number.  A meeting
at which a quorum is initially present may continue to transact business,
notwithstanding withdrawal of directors, if any action taken is approved by at
least a majority of the number of directors constituting a quorum for such
meeting.  In the absence of a quorum at any meeting of

meeting, as provided in Section 31 of these bylaws.

     SECTION 31.     ADJOURNMENT.  Any meeting of the Board of Directors,

is adjourned for more than twenty-four (24) hours, notice of such adjournment
to another time or place shall be given prior to the time of the adjourned
meeting to the directors who were not present at the time of the adjournment.

     SECTION 32.     ORGANIZATION.  The Chairman of the Board shall preside at

corporation or, in the absence of the Secretary, any person appointed by the
Chairman shall act as secretary of the meeting.

     SECTION 33.     COMPENSATION.  Directors and members of committees may
receive such compensation, if any, for their services, and such reimbursement
for expenses, as may be fixed or determined by the Board of Directors.

adopted by a majority of the authorized number of directors, designate one or
more committees, each consisting of two (2) or more directors, to serve at the
pleasure of the Board of Directors.  The Board of Directors, by a vote of the
majority of authorized directors, may designate one or more directors as
alternate members of any committee, to replace any absent member at any meeting
of such committee.  Any such committee shall have authority to act in the
manner and to the extent provided in the resolution of the Board of Directors,
and may have all the authority of the Board of Directors in the management of
the business and affairs of the corporation, except with respect to:

          (a)    the approval of any action for which shareholders' approval or
approval of the outstanding shares also is required by the California

    Any committee may from time to time provide by resolution for regular
meetings at specified times and places.  If the date of such a meeting falls on
a legal holiday, then the meeting shall be held at the same time on the next
succeeding full business day.  No notice of such a meeting need be given.  Such
regular meetings need not be held if the committee shall so determine at any
time before or after the time when such meeting would otherwise have taken
place.  Special meetings may be called at any time in the same manner and by
the same persons as stated in Sections 25 and 26 of these bylaws for meetings
of the Board of Directors.  The provisions of Sections 24, 27, 28, 29, 30 and
31 of these bylaws shall apply to committees, committee members and committee
meetings as if the words "committee" and "committee member" were substituted
for the word "Board of Directors", and "director", respectively, throughout
such sections.

these bylaws may otherwise provide, the Board of Directors or its duly
appointed and authorized committee may authorize any officer or officers, agent
or agents, to enter into any contract or execute and deliver any instrument in
the name of and on behalf of the corporation, and such authorization may be

     SECTION 48.     LOANS.  No loans shall be contracted on behalf of the

institution, or from any firm, corporation or individual, and for such loans
and advances may make, execute and deliver promissory notes, bonds or other
evidences of indebtedness of the corporation and, when authorized as aforesaid,
may mortgage, pledge, hypothecate or transfer any and all stocks, securities
and other property, real or personal, at any time held by the corporation, and

Such authorization may be general or confined to specific instances.

     SECTION 49.     BANK ACCOUNTS.  The Board of Directors or its duly

                                       15
<PAGE>   21



appointed and authorized committee, by resolution, shall have delegated such

                                  ARTICLE VII

                   CERTIFICATES FOR SHARES AND THEIR TRANSFER

     SECTION 51.     CERTIFICATE FOR SHARES.  Every holder of shares in the
corporation shall be entitled to have a certificate signed in the name of the
corporation by the Chairman or Vice Chairman of the Board or the President or a
Vice President and by the Chief Financial Officer or an assistant financial
officer or by the Secretary or an assistant secretary, certifying the number of
shares and the class or series of shares owned by the share-holder.  Any or all
of the signatures on the certificate may be facsimile. In case any officer,
transfer agent or registrar who has signed or whose facsimile signature has
been placed upon a certificate shall have ceased to be such officer, transfer
agent or registrar before such certificate is issued, it may be issued by the
corporation with the same effect as if such person were an officer, transfer
agent or registrar at the date of issue.

    In the event that the corporation shall issue any shares as only partly
paid, the certificate issued to represent such partly paid shares shall have
stated thereon the total consideration to be paid for such shares and the
amount paid thereon.

     SECTION 52.     TRANSFER ON THE BOOKS.  Upon surrender to the Secretary or
transfer agent (if any) of the corporation of a certificate for shares of the
corporation duly endorsed, with reasonable assurance that the endorsement is
genuine and effective, or accompanied by proper evidence of succession,
assignment or authority to transfer and upon compliance with applicable federal
and state securities laws and if the corporation has no statutory duty to
inquire into adverse claims or has discharged any such duty and if any
applicable law relating to the collection of taxes has been complied with, it
shall be the duty of the corporation, by its Secretary or transfer agent, to
cancel the old certificate, to issue a new certificate to the person entitled
thereto and to record the transaction on the books of the corporation.

     SECTION 53.     LOST, DESTROYED AND STOLEN CERTIFICATES.  The holder of
any certificate for shares of the corporation alleged to have been lost,
destroyed or stolen shall notify the corporation by making a written affidavit
or affirmation of such fact.  Upon receipt of said affidavit or affirmation the
Board of Directors, or its duly appointed and authorized committee or any
officer or officers authorized by the board so to do, may order the issuance of
a new certificate for shares in the place of any certificate previously issued
by the corporation and which is alleged to have been lost, destroyed or stolen.
However, the Board of Directors or such authorized committee, officer or
officers may require the owner of the allegedly lost, destroyed or stolen
certificate, or such owner's legal representative, to give the corporation a
bond or other adequate security sufficient to indemnify the corporation and its
transfer agent and/or registrar, if any, against any claim that may be made
against it or them on account of such allegedly lost, destroyed or stolen
certificate or the replacement thereof. Said bond or other security shall be in
such amount, on such terms and conditions and, in the case of a bond, with such
surety or sureties as may be acceptable to the Board of Directors or to its
duly appointed and authorized committee or any officer or officers authorized
by the Board of Directors to determine the sufficiency thereof.  The
requirement of a bond or other security may be waived in particular





                                       16
<PAGE>   22



cases at the discretion of the Board of Directors or its duly appointed and
authorized committee or any officer or officers authorized by the Board of
Directors so to do.

     SECTION 54.     ISSUANCE, TRANSFER AND REGISTRATION OF SHARES.  The Board
of Directors may make such rules and regulations, not inconsistent with law or
with these bylaws, as it may deem advisable concerning the issuance, transfer
and registration of certificates for shares of the capital stock of the
corporation.  The Board of Directors may appoint a transfer agent or registrar
of transfers, or both, and may require all certificates for shares of the
corporation to bear the signature of either or both.

after the record date, except as otherwise provided in the Articles of
Incorporation, by agreement or by law.

     SECTION 61.     BYLAW AMENDMENTS.  Except as otherwise provided by law or
Section 19 of these bylaws, these bylaws may be amended or repealed by the
Board of Directors or by the affirmative vote of sixty-six and two-thirds

of the outstanding shares of each class or series entitled by law or the
Articles of Incorporation to vote as a class or series on the amendment or
repeal or adoption of any bylaw or bylaws; provided, however, after issuance of
shares, a bylaw specifying or changing a fixed number of directors or the
maximum or minimum number or changing from a fixed to a variable board or vice
versa may only be adopted by approval of the outstanding shares as provided
herein.

     SECTION 62.     CONSTRUCTION AND DEFINITION.  Unless the context requires
otherwise, the general provisions, rules of construction, and definitions
contained in the California Corporations Code shall govern the construction of

                                   ARTICLE X

                                INDEMNIFICATION

     SECTION 63.     INDEMNIFICATION OF DIRECTORS, OFFICERS, EMPLOYEES AND
OTHER AGENTS.

          (a)    DIRECTORS.  The corporation shall indemnify its directors to
the fullest extent not prohibited by the California General Corporation Law;
provided, however, that the corporation may limit the extent of such
indemnification by individual contracts with its directors; and, provided,
further, that the corporation shall not be required to indemnify any director
in connection with any proceeding (or part thereof) initiated by such person or
any proceeding by such person against the corporation or its directors,
officers, employees or other agents unless (i) such indemnification is
expressly required to be made by law, (ii) the proceeding was authorized by the
board of directors of the corporation or (iii) such





                                       19
<PAGE>   25

indemnification is provided by the corporation, in its sole discretion,
pursuant to the powers vested in the corporation under the California General
Corporation Law.

          (b)    OFFICERS, EMPLOYEES AND OTHER AGENTS.  The corporation shall
have power to indemnify its officers, employees and other agents as set forth
in the California General Corporation Law.

          (c)    DETERMINATION BY THE CORPORATION.  Promptly after receipt of a
request for indemnification hereunder (and in any event within 90 days thereof)
a reasonable, good faith determination as to whether indemnification of the
director is proper under the circumstances because each director has met the
applicable standard of care shall be made by:

               (1)   a majority vote of a quorum consisting of directors who
are not parties to such proceeding;

               (2)   if such quorum is not obtainable, by independent legal
counsel in a written opinion; or

               (3)   approval or ratification by the affirmative vote of a
majority of the shares of this corporation represented and voting at a duly
held meeting at which a quorum is present (which shares voting affirmatively
also constitute at least a majority of the required quorum) or by written
consent of a majority of the outstanding shares entitled to vote; where in each
case the shares owned by the person to be indemnified shall not be considered
entitled to vote thereon.

          (d)    GOOD FAITH.

               (1)   For purposes of any determination under this bylaw, a
director shall be deemed to have acted in good faith and in a manner he
reasonably believed to be in the best interests of the corporation and its
shareholders, and, with respect to any criminal action or proceeding, to have
had no reasonable cause to believe that his conduct was unlawful, if his action
is based on information, opinions, reports and statements, including financial
statements and other financial data, in each case prepared or presented by:

                    (i)   one or more officers or employees of the corporation
whom the director believed to be reliable and competent in the matters
presented;

                    (ii)  counsel, independent accountants or other persons as
to matters which the director believed to be within such person's professional
competence; and

                    (iii)     a committee of the Board upon which such director
does not serve, as to matters within such committee's designated authority,
which committee the director believes to merit confidence; so long as, in each
case, the director acts without knowledge that would cause such reliance to be
unwarranted.

               (2)   The termination of any proceeding by judgment, order,
settlement, conviction or upon a plea of nolo contendere or its equivalent
shall not, of itself, create a presumption that the person did not act in good
faith and in a manner which he reasonably





                                       20
<PAGE>   26



believed to be in the best interests of the corporation and its shareholders or
that he had reasonable cause to believe that his conduct was unlawful.

               (3)   The provisions of this paragraph (d) shall not be deemed
to be exclusive or to limit in any way the circumstances in which a person may
be deemed to have met the applicable standard of conduct set forth by the
California General Corporation Law.

          (e)    EXPENSES.  The corporation shall advance, prior to the final
disposition of any proceeding, promptly following request therefor, all expenses
incurred by any director in connection with such proceeding upon receipt of an
undertaking by or on behalf of such person to repay said amounts if it shall be
determined ultimately that such person is not entitled to be indemnified under
this bylaw or otherwise.

          (f)    ENFORCEMENT.  Without the necessity of entering into an
express contract, all rights to indemnification and advances to directors under
this bylaw shall be deemed to be contractual rights and be effective to the
same extent and as if provided for in a contract between the corporation and
the director.  Any right to indemnification or advances granted by this bylaw
to a director shall be enforceable by or on behalf of the person holding such
right in the forum in which the proceeding is or was pending or, if such forum
is not available or a determination is made that such forum is not convenient,
in any court of competent jurisdiction if (i) the claim for indemnification or
advances is denied, in whole or in part, or (ii) no disposition of such claim
is made within ninety (90) days of request therefor.  The claimant in such
enforcement action, if successful in whole or in part, shall be entitled to be
paid also the expense of prosecuting his claim.  The corporation shall be
entitled to raise as a defense to any such action (other than an action brought
to enforce a claim for expenses incurred in connection with any proceeding in
advance of its final disposition when the required undertaking has been
tendered to the corporation) that the claimant has not met the standards of
conduct that make it permissible under the California General Corporation Law
for the corporation to indemnify the claimant for the amount claimed.  Neither
the failure of the corporation (including its board of directors, independent
legal counsel or its shareholders) to have made a determination prior to the
commencement of such action that indemnification of the claimant is proper in
the circumstances because he has met the applicable standard of conduct set
forth in the California General Corporation Law, nor an actual determination by
the corporation (including its board of directors, independent legal counsel or
its shareholders) that the claimant has not met such applicable standard of
conduct, shall be a defense to the action or create a presumption that claimant
has not met the applicable standard of conduct.

          (g)    NON-EXCLUSIVITY OF RIGHTS.  To the fullest extent permitted by
the corporation's Articles of Incorporation and the California General
Corporation Law, the rights conferred on any person by this bylaw shall not be
exclusive of any other right which such person may have or hereafter acquire
under any statute, provision of the Articles of Incorporation, bylaws,
agreement, vote of shareholders or disinterested directors or otherwise, both
as to action in his official capacity and as to action in another capacity
while holding office.  The corporation is specifically authorized to enter into
individual contracts with any or all of its directors, officers, employees or
agents respecting indemnification and advances, to the fullest extent permitted
by the California General Corporation Law and the corporation's Articles of
Incorporation.





                                       21
<PAGE>   27

          (h)    SURVIVAL OF RIGHTS.  The rights conferred on any person by
this bylaw shall continue as to a person who has ceased to be a director and
shall inure to the benefit of the heirs, executors and administrators of such a
person.

          (i)    INSURANCE.   The corporation, upon approval by the board of
directors, may purchase insurance on behalf of any person required or permitted
to be indemnified pursuant to this bylaw.

          (j)    AMENDMENTS.  Any repeal or modification of this bylaw shall
only be prospective and shall not affect the rights under this bylaw in effect
at the time of the alleged occurrence of any action or omission to act that is
the cause of any proceeding against any agent of the corporation.

          (k)    EMPLOYEE BENEFIT PLANS.  The corporation shall indemnify the
directors and officers of the corporation who serve at the request of the
corporation as trustees, investment managers or other fiduciaries of employee
benefit plans to the fullest extent permitted by the California General
Corporation Law.

          (l)    SAVING CLAUSE.  If this bylaw or any portion hereof shall be
invalidated on any ground by any court of competent jurisdiction, then the
corporation shall nevertheless indemnify each director to the fullest extent
permitted by any applicable portion of this bylaw that shall not have been
invalidated, or by any other applicable law.

          (m)    CERTAIN DEFINITIONS.  For the purposes of this bylaw, the
following definitions shall apply:

               (1)   The term "proceeding" shall be broadly construed and shall
include, without limitation, the investigation, preparation, prosecution,
defense, settlement and appeal of any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative, arbitrative or
investigative.

               (2)   The term "expenses" shall be broadly construed and shall
include, without limitation, court costs, attorneys' fees, witness fees, fines,
amounts paid in settlement or judgment and any other costs and expenses of any
nature or kind incurred in connection with any proceeding, including expenses
of establishing a right to indemnification under this bylaw or any applicable
law.

               (3)   The term the "corporation" shall include, in addition to
the resulting corporation, any constituent corporation (including any
constituent of a constituent) absorbed in a consolidation or merger which, if
its separate existence had continued, would have had power and authority to
indemnify its directors, officers, and employees or agents, so that any person
who is or was a director, officer, employee or agent of such constituent
corporation, or is or was serving at the request of such constituent
corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, shall stand in the same
position under the provisions of this bylaw with respect to the resulting or
surviving corporation as he would have with respect to such constituent
corporation if its separate existence had continued.





                                       22
<PAGE>   28

               (4)   References to a "director," "officer," "employee," or
"agent" of the corporation shall include, without limitation, situations where
such person is serving at the request of the corporation as a director,
officer, employee, trustee or agent of another corporation, partnership, joint
venture, trust or other enterprise.

                                   ARTICLE XI

                          LOANS OF OFFICERS AND OTHERS

     SECTION 64.     CERTAIN CORPORATE LOANS AND GUARANTIES.  If the
corporation has outstanding shares held of record by 100 or more persons on the
date of approval by the Board of Directors, the corporation may make loans of
money or property to, or guarantee the obligations of, any officer of the
corporation or its parent or any subsidiary, whether or not a director of the
corporation or its parent or any subsidiary, or adopt an employee benefit plan
or plans authorizing such loans or guaranties, upon the approval of the Board
of Directors alone, by a vote sufficient without counting the vote of any
interested director or directors, if the Board of Directors determines that
such a loan or guaranty or plan may reasonably be expected to benefit the
corporation.

                                  ARTICLE XII

                             RIGHT OF FIRST REFUSAL

     SECTION 65.     RIGHT OF FIRST REFUSAL.  No shareholder shall sell,
assign, pledge, or in any manner transfer any of the shares of Common Stock of
the corporation or any right or interest therein, whether voluntarily or by
operation of law, or by gift or otherwise, except by a transfer which meets the
requirements hereinafter set forth in this bylaw:

          (a)    If the shareholder desires to sell or otherwise transfer any
of his shares of Common Stock, then the shareholder shall first give written
notice thereof to the corporation.  The notice shall name the proposed
transferee and state the number of shares to be transferred, the proposed
consideration, and all other terms and conditions of the proposed transfer.

          (b)    For thirty (30) days following receipt of such notice, the
corporation shall have the option to purchase all (but not less than all) of
the shares specified in the notice at the price and upon the terms set forth in
such notice; provided, however, that, with the consent of the shareholder, the
corporation shall have the option to purchase a lesser portion of the shares
specified in said notice at the price and upon the terms set forth therein.  In
the event of a gift or property settlement that is not otherwise exempted from
the provisions of this Section 64, the price shall be deemed to be the fair
market value of the Common Stock at such time as deter-mined in good faith by
the Board of Directors.  In the event the corporation elects to purchase all of
the shares or, with consent of the shareholder, a lesser portion of the shares,
it shall give written notice to the transferring shareholder of its election
and settlement for said shares shall be made as provided below in subsection
(d).  In the event the selling shareholder does not agree with the non-cash
valuation of the shares set by the Board of Directors, the Company shall engage
an independent appraiser to value the price of the shares.  The selling
shareholder shall have the right to approve the appraiser.  The cost of the
valuation shall be shared equally by the Company and the selling shareholder.





                                       23
<PAGE>   29

          (c)    The corporation may assign its rights hereunder.

          (d)    In the event the corporation and/or its assignee(s) elect to
acquire any of the shares of the transferring shareholder as specified in said
transferring shareholder's notice, the Secretary of the corporation shall so
notify the transferring shareholder and settlement thereof shall be made in
cash within thirty (30) days after the Secretary of the corporation receives
said transferring shareholder's notice; provided that if the terms of payment
set forth in said transferring shareholder's notice were other than cash
against delivery, the corporation and/or its assignee(s) shall pay for said
shares on the same terms and conditions set forth in said transferring
shareholder's notice.

          (e)    In the event the corporation and/or its assignees(s) do not
elect to acquire all of the shares specified in the transferring shareholder's
notice, said transferring shareholder may, within the sixty-day period
following the expiration of the option rights granted to the corporation and/or
its assignees(s) herein, transfer the shares specified in said transferring
shareholder's notice which were not acquired by the corporation and/or its
assignees(s) as specified in said transferring shareholder's notice.  All
shares so sold by said transferring shareholder shall continue to be subject to
the provisions of this bylaw in the same manner as before said transfer.

          (f)    Anything to the contrary contained herein notwithstanding, the
following transactions shall be exempt from the provisions of this bylaw:

               (1)   A shareholder's transfer of any or all shares held either
during such shareholder's lifetime or on death by will or intestacy to such
shareholder's immediate family or to any custodian or trustee for the account
of such shareholder or such shareholder's immediate family. "Immediate family"
as used herein shall mean spouse, lineal descendant, father, mother, brother,
or sister of the shareholder making such transfer.

               (2)   A shareholder's bona fide pledge or mortgage of any shares
with a commercial lending institution, provided that any subsequent transfer of
said shares by said institution shall be conducted in the manner set forth in
this bylaw.

               (3)   A shareholder's transfer of any or all of such
shareholder's shares to the corporation or to any other shareholder of the
corporation.

               (4)   A shareholder's transfer of any or all of such
shareholder's shares to a person who, at the time of such transfer, is an
officer or director of the corporation.

               (5)   A corporate shareholder's transfer of any or all of its
shares pursuant to and in accordance with the terms of any merger,
consolidation, reclassification of shares or capital reorganization of the
corporate shareholder, or pursuant to a sale of all or substantially all of the
stock or assets of a corporate shareholder.

               (6)   A corporate shareholder's transfer of any or all of its
shares to any or all of its shareholders.

<PAGE>   30

               (7)   A transfer by a shareholder which is a limited or general
partnership to any or all of its partners or former partners.

         In any such case, the transferee, assignee, or other recipient shall
receive and hold such Common Stock subject to the provisions of this bylaw, and
there shall be no further transfer of such Common Stock except in accord with
this bylaw.

          (g)    The provisions of this bylaw may be waived with respect to any
transfer either by the corporation, upon duly authorized action of its Board of
Directors, or by the share-holders, upon the express written consent of the
owners of a majority of the voting power of the corporation (excluding the
votes represented by those shares to be transferred by the transferring
shareholder).  This bylaw may be amended or repealed either by a duly
authorized action of the Board of Directors or by the shareholders, upon the
express written consent of the owners of a majority of the voting power of the
corporation.

          (h)    Any sale or transfer, or purported sale or transfer, of
securities of the corporation shall be null and void unless the terms,
conditions, and provisions of this bylaw are strictly observed and followed.

          (i)    The foregoing right of first refusal shall terminate on either
of the following dates, whichever shall first occur:

               (1)   On September 29, 2002; or

               (2)   Upon the date securities of the corporation are first
offered to the public pursuant to a registration statement filed with, and
declared effective by, the United States Securities and Exchange Commission
under the Securities Act of 1933, as amended.

          (j)    The certificates representing shares of Common Stock of the
corporation shall bear on their face the following legend so long as the
foregoing right of first refusal remains in effect:

         "HE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A RIGHT OF
         FIRST REFUSAL OPTION IN FAVOR OF THE CORPORATION AND/OR ITS
         ASSIGNEE(S), AS PROVIDED IN THE BYLAWS OF THE CORPORATION."

participation on behalf of any person.

     2.7     NO CONFLICT.  The execution and delivery of this Agreement does
not, and the consummation of the transactions contemplated hereby will not,
conflict with, or result in any violation of or default (with or without notice

cancellation or acceleration of any obligation or to a loss of material

truth and accuracy of Purchasers' representations and warranties in Section 4
of this Agreement, the offer, sale and issuance of the Common Stock is exempt
from registration under the Securities Act of 1933, as amended.

           REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE PURCHASERS

    Each of the Purchasers represents and warrants to, and covenants with, the

     2.12    AUTHORITY.  Such Purchaser has full right, power, authority and
capacity to enter into this Agreement and to consummate the transactions
contemplated hereby. This Agreement has been duly executed and delivered by
such Purchaser and constitutes a legal, valid and binding obligation of such
Purchaser enforceable in accordance with its terms, subject to laws of general
application relating to bankruptcy, insolvency and the relief of debtors and
rules of law governing specific performance, injunctive relief or other
equitable remedies, and to limitations of public policy as they may apply to
the indemnification provisions set forth in Section 7.3 of this Agreement.

     2.13    INVESTMENT EXPERIENCE; INVESTMENT INTENT; ETC.  (i) The Purchaser
is knowledgeable, sophisticated and experienced in making, and is qualified to
make, decisions with respect to investments in shares presenting an investment
decision like that involved in the purchase of the Shares; (ii) the Purchaser
is acquiring the number of Shares to be purchased by it in the ordinary course
of its business and for its own account solely for investment and with no
present intention of distributing any of such Shares, and no arrangement or
understanding exists with any other person regarding the distribution of such
Shares; (iii) the Purchaser will not, directly or indirectly, offer, sell,
pledge, transfer or otherwise dispose of (or solicit any offers to buy,
purchase or otherwise acquire or take a pledge of) any of the Shares except in
compliance with the Securities Act, and the rules and regulations promulgated
thereunder; and (iv) the Purchaser is an "accredited investor" within the
meaning of Rule 501 of Regulation D promulgated under the Securities Act.

     2.14    PURCHASER UNDERSTANDING AND AGREEMENTS.  The Purchaser
acknowledges and agrees that it will acquire the shares being purchased by it
in transactions not involving a public offering and that such shares are
subject to certain restrictions as to resale under the federal and state
securities laws. The Purchaser agrees and understands that, until satisfaction
of the prospectus delivery requirement (pursuant to an effective registration
statement under the Securities Act) in connection with each subsequent transfer
of any of the Shares, stop transfer instructions will be given to the transfer
agent for the Shares and each Share Certificate, and each certificate delivered
on transfer of or in substitution for any such certificate, shall bear a legend
in substantially the following form:

         THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS
         IMPOSED BY THE SECURITIES ACT OF 1933, AS AMENDED, AND APPLICABLE
         STATE SECURITIES LAW.  THE SHARES MAY NOT BE SOLD OR TRANSFERRED IN
         THE ABSENCE OF REGISTRATION OR AN EXEMPTION THEREFROM UNDER THE
         SECURITIES ACT OF 1933 AND ANY APPLICABLE STATE SECURITIES LAWS.

    The Purchaser agrees that it will not sell, pledge, assign, transfer or
otherwise dispose (collectively, "Transfer") of any of the Shares unless the
Transfer will be made pursuant to an exemption from the registration
requirements of the Securities Act or pursuant to an effective registration
statement under the Securities Act and pursuant to an exemption from any
applicable state securities laws or an effective registration or other
qualification under any applicable state securities laws.  The Purchaser
understands that exemptions from such registration requirements are limited.
The Company is under no obligation to register the Shares, except as provided
in Section 7.

     2.15    NO LEGAL, TAX OR INVESTMENT ADVICE.  The Purchaser understands
that nothing in this Agreement or any other materials presented to the
Purchaser in connection with the purchase of the Common Stock constitutes
legal, tax or investment advice. The Purchaser has consulted such





                                       4

legal, tax and investment advisors as it, in its sole discretion, has deemed
necessary or appropriate in connection with its purchase of the Common Stock.

<PAGE>   6

          (c)    the term "Registrable Shares" shall mean the shares of Common
Stock issued pursuant to this Agreement.

     2.23    REGISTRATION PROCEDURES AND EXPENSES.  The Company shall:

          (a)    use its best efforts to file a registration statement with the
SEC within thirty (30) days following the Closing Date to register the
Registrable Shares on Form S-3 under the Securities Act (providing for shelf
registration of the Common Stock under SEC Rule 415) or on such other form
which is appropriate to register all of the Registrable Shares for resale from
time to time by the Purchasers;

          (b)    use its best efforts, subject to receipt of necessary
information from the Purchasers, to cause such Registration Statement to become
effective as promptly after filing as practicable, and in any event, within
ninety (90) days following the Closing Date, and to cause (at the Company's
expense) Cooley Godward LLP, counsel to the Company, to furnish to each
Purchaser an opinion dated as of the effective date to the effects set forth in
EXHIBIT B;

          (c)    prepare and file with the SEC such amendments and supplements
to such Registration Statement and the prospectus used in connection therewith
as may be necessary to keep such Registration Statement effective until
termination of such obligation as provided in Section 7.5 below, subject to the
Company's right to suspend pursuant to Section 7.4;

          (d)    furnish to each Purchaser (and to each underwriter, if any, of
such Common Stock) such number of copies of prospectuses in conformity with the
requirements of the Securities Act and such other documents as the Purchasers
may reasonably request, in order to facilitate the public sale or other
disposition of all or any of the Registrable Shares by the Purchasers;

          (e)    file such documents as may be required of the Company for
normal securities law clearance for the resale of the Registrable Shares in
such states of the United States as may be reasonably requested by each
Purchaser; provided, however, that the Company shall not be required in
connection with this paragraph (e) to qualify as a foreign corporation or
execute a general consent to service of process in any jurisdiction;

          (f)    advise each Purchaser promptly:

               (i)   of any request by the SEC for amendments to the
Registration Statement or amendments to the prospectus or for additional
information relating thereto:

               (ii)  of the issuance by the SEC of any stop order suspending
the effectiveness of the Registration Statement under the Securities Act or of
the suspension by any state securities commission of the qualification of the
Registrable Shares for offering or sale in any jurisdiction, or the initiation
of any proceeding for any of the preceding purposes; and

               (iii) of the existence of any fact and the happening of any
event that makes any statement of a material fact made in the Registration
Statement, the prospectus and amendment or supplement thereto, or any document
incorporated by reference therein, untrue, or that requires the making of any
additions to or changes in the Registration Statement or the prospectus in
order to make the statements therein not misleading;





                                       6
<PAGE>   7

          (g)    in connection with the filing of any document that is to be
incorporated by reference into the Registration Statement or the prospectus
(after the initial filing of the Registration Statement):

               (i)   use its best efforts to provide copies of such document to
the Purchasers concurrently with such filing; and

               (ii)  make a Company representative available for discussion of
such document;

          (h)    use its best efforts to cause all Registrable Shares to be
listed on each securities exchange, if any, on which equity securities by the
Company are then listed; and

          (i)    bear all expenses in connection with the procedures in
paragraphs (a) through (h) of this Section 7.2 and the registration of the
Registrable Shares on such Registration Statement and the satisfaction of the
blue sky laws of such states.

     2.24    INDEMNIFICATION.

          (a)    The Company agrees to indemnify and hold harmless Purchaser
from and against any losses, claims, damages or liabilities to which such
Purchaser may become subject (under the Securities Act or otherwise) insofar as
such losses, claims, damages or liabilities (or actions or proceedings in
respect thereof) arise out of, or are based upon, any untrue statement or
alleged untrue statement of a material fact contained in the Registration
Statement or any omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, in each case on the effective date thereof, or arise out of any
failure by the Company to fulfill any undertaking included in the Registration
Statement, and the Company will, as incurred, reimburse such Purchaser for any
legal or other expenses reasonably incurred in investigating, defending or
preparing to defend any such action, proceeding or claim; provided, however,
that the Company shall not be liable in any such case to the extent that such
loss, claim, damage or liability arises out of, or is based upon, an untrue
statement or omission or alleged untrue statement or omission made in such
Registration Statement in reliance upon and in conformity with written
information furnished to the Company by or on behalf of such Purchaser
specifically for use in preparation of the Registration Statement or any breach
of this Agreement by Purchaser.

          (b)    Each Purchaser, severally and not jointly, agrees to indemnify
and hold harmless the Company (and each person, if any, who controls the
Company within the meaning of Section 5 of the Securities Act or Section 20 of
the Exchange Act, each officer of the Company who signs the Registration
Statement and each director of the Company), from and against any losses,
claims, damages or liabilities to which the Company (or any such officer,
director or controlling person) may become subject (under the Securities Act or
otherwise), insofar as such losses, claims, damages or liabilities (or actions
or proceedings in respect thereof) arise out of, or are based upon, any breach
of this Agreement by such Purchaser or any untrue statement of a material fact
contained in the Registration Statement or any omission or alleged omission to
state therein a material fact required to be stated therein or necessary to
make the statements therein not misleading in each case, on the effective date
thereof, if, and to the extent, such untrue statement





                                       7
<PAGE>   8



was made in reliance upon and in conformity with written information furnished
by or on behalf of such Purchaser specifically for use in preparation of the
Registration Statement, and such Purchaser will reimburse the Company (and each
of its officers, directors or controlling persons) for any legal or other
expenses reasonably incurred in investigating, defending or preparing to defend
any such action, proceeding or claim.

          (c)    Promptly after receipt by any indemnified person of a notice
of a claim or the beginning of any action in respect of which indemnity is to
be sought against an indemnifying person pursuant to this Section 7.3, such
indemnified person shall notify the indemnifying person in writing of such
claim or of the commencement of such action, and, subject to the provisions
hereinafter stated, in case any such action shall be brought against an
indemnified person and such indemnifying person shall have been notified
thereof, such indemnifying person shall be entitled to participate therein,
and, to the extent that it shall wish, to assume the defense thereof, with
counsel reasonably satisfactory to such indemnified person.  After notice from
the indemnifying person to such indemnified person of its election to assume
the defense thereof, such indemnifying person shall not be liable to such
indemnified person for any legal expenses subsequently incurred by such
indemnified person in connection with the defense thereof; provided, however,
that if there exists or shall exist a conflict of interest that would make it
inappropriate in the reasonable judgment of the indemnified person for the same
counsel to represent both the indemnified person and such indemnifying person
or any affiliate or associate thereof, the indemnified person shall be entitled
to retain its own counsel at the expense of such indemnifying person; provided,
further, that no indemnifying person shall be responsible for the fees and
expenses of more than one separate counsel for all indemnified parties.  The
indemnifying party shall not settle an action without the consent of the
indemnified party, which shall not be unreasonably withheld.

          (d)    If after proper notice of a claim or the commencement of any
action against the indemnified party, the indemnifying party does not choose to
participate, then the indemnified party shall defend itself at its own cost and
expense until there is an adjudication at which point the indemnifying party
shall then reimburse the indemnified party for its costs and expenses.

          (e)    If the indemnification provided for in this Section 7.3 is
required by its terms but is for any reason held to be unavailable to or
otherwise insufficient to hold harmless an indemnified party in respect of any
losses, claims, damages or liabilities referred to above, then each applicable
indemnifying party shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages or liabilities.

     2.25    PROSPECTUS DELIVERY.  The Purchaser hereby covenants with the
Company not to make any sale of the Shares after registration without
effectively causing the prospectus delivery requirement under the Securities
Act to be satisfied. The Purchaser acknowledges that there may be times when
the Company must suspend the use of the prospectus forming a part of the
Registration Statement until such time as an amendment to the Registration
Statement has been filed by the Company and declared effective by the SEC, or
until such time as the Company has filed an appropriate report with the SEC
pursuant to the Exchange Act. The Purchaser hereby covenants that it will not
sell any Shares pursuant to said prospectus during the period commencing at the
time at which the Company gives the Purchaser notice of the suspension of the
use of said prospectus and ending at the time the Company gives the Purchaser
notice that the Purchaser may thereafter effect





                                       8
<PAGE>   9

sales pursuant to said prospectus. Such suspension periods shall in no event
exceed 60 days in any 12 month period.

     2.26    TERMINATION OF OBLIGATIONS.  The obligations of the Company
pursuant to Section 7.2 hereof shall cease and terminate upon the earlier to
occur of (i) such time as all of the Registrable Shares have been re-sold, or
(ii) such time as all of the Registrable Shares may be re-sold pursuant to Rule
144(k).

     2.27    REPORTING REQUIREMENTS.

          (a)  With a view to making available the benefits of certain rules and
regulations of the SEC that may at any time permit the sale of the Shares to the
public without registration or pursuant to a registration statement on Form S-3,
the Company agrees to use its best efforts to:

               (i)   make and keep public information available, as those terms
are understood and defined in Rule 144 under the Securities Act;

               (ii)  file with the SEC in a timely manner all reports and other
documents required of the Company under the Securities Act and the Securities
Exchange Act of 1934; and

               (iii) so long as any of the Purchasers own Registrable
Securities, to furnish to the Purchasers forthwith upon request (1) a written
statement by the Company as to whether it is in compliance with the reporting
requirements of said Rule 144, the Securities Act and Securities Exchange Act
of 1934, or whether it is qualified as a registrant whose securities may be
resold pursuant to SEC Form S-3, and (2) a copy of the most recent annual or
quarterly report of the Company and such other reports and documents so filed
by the Company.

SECTION 2.    -   DEVELOPMENT ACTIVITIES AND RESPONSIBILITIES

     2.1     NOVO NORDISK and ARADIGM shall jointly conduct the Development
Programme, which shall initially consist of Diligent Efforts by the parties to
carry out a development plan addressing development of the Device and a
Packaged Product containing the Initial Compound for administration using the
Device.  The preliminary details of such development plan have been agreed upon
by the parties and are set forth in a separate document entitled "Milestone
Plan."  The details of this development plan shall be discussed and agreed on
in good faith between the parties and embodied in a document signed by both
parties, which shall thereafter be subject to further modification from time to
time as approved by the Steering Committee.  The product description for the
Packaged Product and the Device, including the Minimum Product Profile as well
as desired target profiles, shall be agreed by NOVO NORDISK and ARADIGM and
shall be included in the document defining the Development Programme.  It is
understood between the parties that the specifications for the Packaged Product
and the Device may require some changes during the course of the programme and
that such changes will be made when and as approved by the Steering Committee.
NOVO NORDISK shall specify within [...***...] after the initiation of a Phase
III trial of the initial Packaged Product one or more Other Compounds for study
by the Steering Committee as candidates for the second Packaged Product to be
added to the Development Programme and may from time to time thereafter propose
additional Other Compounds for the Development Programme.  Upon agreement by
the parties on a development plan to incorporate the preliminary details for
the development of such Other Compounds and determination by the Steering
Committee that such development is feasible and should be undertaken, such
Other Compounds will be added to the Development Progr*amme.  Each time an
Other Compound is added to the Development Programme in this manner, the
parties will agree in good faith on the financial terms not otherwise specified
herein for such development and commercialization, which will provide for a
reasonable sharing of the potential value of the Packaged Product containing
such compound, as well as on such other modifications of the other terms hereof
as may be reasonable under the circumstances.

     2.2     A Steering Committee will be established, consisting of an equal
number of people (at least three) from each party, whose responsibility will be
to ensure the Development Programme is carried out to the satisfaction of both
parties. The Steering Committee, [...***...], shall have responsibility for

resolution.  While in general the parties intend to act by mutual agreement,
with respect to issues concerning the design and implementation of clinical
trials and approval of specifications as provided in Article 4.9(d), the senior
management of NOVO NORDISK shall have the right to make the final decision.

     2.3     ARADIGM agrees that it will use Diligent Efforts to develop,
manufacture and supply, to the deadlines included in the Development Programme
agreed between the parties, the Packaged Product and the Device consistent with
Good Manufacturing Practice and any other relevant practices as required to
obtain Regulatory Approval for the Device and the Packaged Product in all major
markets in the Territory.  ARADIGM shall use Diligent Efforts to obtain all the
required Regulatory Approvals in the Territory required for NOVO NORDISK
commercialization of the Device with the Packaged Products.  However, in such
cases where the Device Regulatory Submission is an integrated part of the
Regulatory Submission, then ARADIGM shall only timely submit to NOVO NORDISK
all the sections of the Regulatory Submission which are required for obtaining
Regulatory Approval of the Device with the Packaged Products.  For countries
other than the United States, NOVO NORDISK shall provide reasonable
non-monetary assistance in structuring such Device Regulatory Submission,
provided NOVO NORDISK has the necessary experience to provide such assistance.
The personnel of NOVO NORDISK having relevant expertise in technical areas
affecting ARADIGM's activities directed to product development, production
process development and manufacturing scale-up and cost reduction, including
those pertaining to the Device as well as the Packaged Product, shall
participate or advise in the Development Programme in such manner as is
approved by the Steering Committee.

     2.4     The Development Costs necessary for activities after the Effective
Date required to develop the Packaged Product and the Device as specified in
the Development Programme referred to in Article 2.1 shall be allocated and
paid as described below:

For the avoidance of doubt, each of the amounts referred to in [...***...]
shall be payable only once.  Moreover, no further payments in respect of such
milestones will become due once NOVO NORDISK has paid ARADIGM a total of
[...***...].  Consequently, maximum total milestone payments to be paid by NOVO
NORDISK to ARADIGM under this Agreement in respect of such milestones shall
amount to [...***...].

Thus, the total milestone payments in respect of the Packaged Product
containing the second Programme Compound will be [...***...], plus milestone
amounts in respect of regulatory submission and approvals thereof to be agreed
upon at the time it is added to the Development Programme.  Upon request by
NOVO NORDISK to develop a third Programme Compound in the Development Programme
pursuant to Article 2.1, the parties will agree in good faith on the milestone
payments to apply to the clinical development of Packaged Products containing
such Other Compound.

Furthermore, NOVO NORDISK shall invest up to a total of USD ten million (USD
10,000,000) equity in ARADIGM at times and under terms as specified in a
separate agreement between the parties.

     2.5     Development Costs of ARADIGM to be borne by NOVO NORDISK will be
paid quarterly [...***...] by NOVO NORDISK based on budgeted expenses approved
by the Steering Committee, subject to a reconciliation to actual costs incurred
at the end of each year (based on a presentation to the Steering Committee no
later than sixty (60) days after the end of such year) approved by the Steering
Committee (such approval not to be unreasonably withheld or delayed) or more
frequently if requested by either party.  NOVO NORDISK shall pay or ARADIGM
shall refund, as applicable, any difference between amounts advanced and actual
costs incurred within thirty (30) days after such reconciliation is approved.
Any anticipated material deviations from established budgets will be reported
as promptly as practicable to the Steering Committee.

     4.3     ARADIGM shall supply all clinical trial quantities and all
commercial quantities of the Packaged Products and the Device to NOVO NORDISK
in a timely fashion in accordance with the Supply Agreement.

     4.4     For the quantities referred to in Article 4.3 above, NOVO NORDISK
shall [...***...] supply sufficient amounts of each Programme Compound in solid
bulk form for filling and packaging of the Packaged Products by ARADIGM in a
timely fashion.

     4.5     ARADIGM shall supply the clinical trial quantities of the Packaged
Products referred to in Article 4.3 above at its Development Cost.  As payment
for the commercial quantities of the Packaged Product referred to in Article
4.3 above, NOVO NORDISK shall [...***...]. For clinical trial supplies of the
Packaged Products, the Development Costs will be estimated by the parties and
paid quarterly in advance by NOVO NORDISK based on the forecasted number of
units to be produced for the Development Programme in such quarter, subject to
reconciliation to actual costs and the actual number of units produced at the
end of each year.  For commercial supplies of the Packaged Products,
[...***...] will be estimated annually by the parties to establish an interim
transfer price, subject to reconciliation at the end of each year.  Payment of
the interim transfer price will be made net 30 days from date of shipment by
ARADIGM.

     4.6     As payment for the clinical trial quantities of the Device
referred to in Article 4.3 above, NOVO NORDISK shall [...***...].  The parties
will cooperate to minimize the number of such units required, consistent with
meeting the objectives of the Development Programme, and will provide for
re-use of Devices to the extent practicable.  As payment for the commercial

year based on anticipated commercial pricing for the coming year.  Payment of
the interim transfer price will be made net thirty (30) days from date of
shipment by ARADIGM.

     4.7     NOVO NORDISK may following consultation with ARADIGM, at its sole
cost and for the purpose of ensuring sufficient security of supply, choose to
establish and operate a second commercial production facility for the Packaged
Product or the Device, at a site owned either by NOVO NORDISK or by ARADIGM, at
the election of ARADIGM.  The location  of the second site of manufacture shall
be negotiated in good faith between the parties hereto, but NOVO NORDISK may
require that it be located at least fifty (50) miles from the first production
facility.  ARADIGM will provide NOVO NORDISK with any non-monetary assistance
required to design and construct a second site.  All costs directly related to
such transfer of manufacture will be borne by NOVO NORDISK.  In the event
ARADIGM elects to own such facility, it will do so through an Affiliate
established for the sole purpose of owning and operating such facility, and
NOVO NORDISK will not bear any such transfer costs or the cost of that portion
of such facility that will be used by ARADIGM to meet the needs of its other
customers.  In the event NOVO NORDISK is the owner of such facility, its
license under Article 3.1 above shall be enlarged to include the right to make
Devices and/or Packaged Products, as applicable, at such facility, and ARADIGM
shall continue to share in the Gross Profit as contemplated by Article 5.
Regardless of which party owns such facility, [...***...] of product produced,
[...***...], will be included in the calculation of Gross Profit.

     4.8     ARADIGM agrees to keep NOVO NORDISK informed as to its financial
condition during the term of this Agreement.  If at any time the financial
resources of ARADIGM are not reasonably sufficient to enable it to continue to
meet its obligations hereunder for at least the next six (6) months, the
parties will meet to review and consider steps that might be taken to ensure
that ARADIGM will be able to perform.  Such steps could include, but are not
limited to, the termination of ARADIGM activities that it is not contractually
obligated to perform in order to conserve resources.  If steps implemented by
ARADIGM are not sufficient to correct the situation within a sixty (60) day
period and ARADIGM cannot demonstrate to the reasonable satisfaction of NOVO
NORDISK that it will be able to complete any needed financing within the next
thirty (30) days, (a) then NOVO NORDISK shall have the right but not the
obligation to provide such financing on terms and conditions, including
security, that are reasonable under the circumstances and (b) if this situation
arises after Regulatory Approval, NOVO NORDISK may also exercise its right to
have a second commercial facility established pursuant to Article 4.7 and in
this case ARADIGM shall not have the right to elect to own such facility.

     4.9     The Supply Agreement will, in addition to the foregoing, contain
terms and conditions consistent with the following principles:

                 (a) Devices and Packaged Products will be supplied by ARADIGM
                     in final packaging or, if it is more efficient, in primary
                     packaging with secondary packaging to be done by NOVO
                     NORDISK (and [...***...] of any such secondary packaging
                     will be included in the calculation of Gross Profit).

                 (b) NOVO NORDISK, as part of its sales and marketing
                     responsibility, will provide [...***...], but ARADIGM will
                     provide [...***...] (the costs of which

                     negligence or fault cannot be so determined or allocated,
                     then such liability shall be borne [...***...].

                 (e) In view of the need to ensure customer satisfaction, NOVO
                     NORDISK's customer service operation is expected to accept
                     returns and provide replacements of products in response to
                     customer complaints often without reference to whether or
                     not such product was defective. Replacement product will be
                     pulled from regular inventories [...***...].

                 (f) NOVO NORDISK will also have the right to order samples of
                     product containing active compound or placebo (i.e.,
                     product that is ordered, labeled and distributed as sample
                     product), which ARADIGM will supply at [...***...] and such
                     cost will not be included in the calculation of Gross
                     Profit. 

                 (g) ARADIGM will carry insurance against such risks and in such
                     amounts as is reasonable under the circumstances, including
                     insurance of bulk compound supplied by NOVO NORDISK against
                     loss and other casualties that can be reasonably insured
                     against. Since the efficiency with which bulk compound is
                     packaged into Packaged Product is an important cost factor,
                     ARADIGM and NOVO NORDISK will jointly develop and review
                     all aspects of the production process that affect
                     efficiency. If, notwithstanding these efforts, production
                     efficiencies are predicted to be below objectives
                     established by the Steering Committee [...***...], the
                     parties will meet to consiDEr corrective action, and any
                     improvements that are reasonable in light of anticipated
                     capital expenditures and the impact on profitability will
                     be implemented by ARADIGM. 

                 (h) In the event that this Agreement is terminated by NOVO
                     NORDISK pursuant to Article 9.7 or by ARADIGM other than
                     for a breach by NOVO NORDISK and if in such case NOVO
                     NORDISK elects to continue the commercialization of
                     Packaged Products and Devices, then NOVO NORDISK shall have
                     a right to set-up at its sole cost production facilities
                     for Packaged Products and Devices and ARADIGM shall in such
                     case provide NOVO NORDISK with access to all necessary or
                     useful documentation for its existing facilities and
                     reasonable non-monetary assistance required by NOVO NORDISK
                     for setting up such production facilities. Furthermore, in
                     such case NOVO NORDISK shall be granted a license to all
                     necessary rights under ARADIGM Patents and ARADIGM Know-How
                     required for production of Packaged Products and Devices in
                     its facilities. In such case ARADIGM shall continue to be
                     entitled to receive on an ongoing basis its [...***...] as
                     specified in Article 5.2, but reduced by the [...***...]
                     associated with thE transfer prices, as specified in
                     Articles 4.5 and 4.6, which shall be retained by NOVO
                     NORDISK as compensation for being required to undertake the
                     manufacturing function.

     4.10    In light of the length of time necessary to establish production
capacity, the Steering Committee will address long range capacity planning as a
part of the Development Programme. Within [...***...] of the Effective Date,
NOVO NORDISK will present to the Steering Committee a non-binding, long-term
forecast [...***...] of projected Device and Packaged Product unit sales on a
worldwide basis. Such forecast will be updated from time to time as part of NOVO
NORDISK's standard strategic planning process and such updates and any interim
forecast changes will be provided to the Steering Committee to ensure that
significant decisions with respect to capacity plans are made on the basis of
the most recent market forecasts. Subject to the review and approval of the
Steering Committee, ARADIGM and NOVO NORDISK will develop plans and associated
time lines for establishing needed

production capacity for [...***...] for at least [...***...] after First
Marketing. Each party will keep the other fully informed as to the status of
implementation of those aspects of such plans for which such party is
responsible. The Steering Committee will also assess the flexibility of the
planned production capacity to respond to changes in market demand and will
supervise the establishment of forecasting and order lead time procedures that
will optimize overall supply chain efficiency. It is the goal of the parties
that the ARADIGM will produce and ship product to NOVO NORDISK substantially as
follows:

             (a)     Once each quarter, NOVO NORDISK shall provide a [...***...]
rolling forecast to ARADIGM projecting unit volumes for Packaged Product and
Devices on a worldwide basis. The forecast for the first quarter will be binding
and may not be changed from the previous forecast. The second quarter forecast
may be changed by plus or minus [...***...] from the previous forecast. The
third quarter forecast may be changed by plus or minus [...***...] from the
previous forecast. The fourth quarter may be changed by plus or minus
[...***...] from the previous forecast. The fifth and sixth quarters may be
changed without limit subject to the limits of production capacity. The first
six quarter rolling order forecast will be provided to ARADIGM no later than
[...***...] months prior to First Marketing. The Steering Committee will review
and establish actual forecast and order procedures, which will be incorporated
in the Supply Agreement.

             (b)     NOVO NORDISK and ARADIGM shall use diligent efforts to keep
each other informed concerning changes in demand or capability to meet demand
and shall use diligent efforts to meet requests for changes in the forecast that
do not comply with the foregoing. 

             (c)     The Steering Committee will have the responsibility to
review and approve ARADIGM's inventory policies including the amounts carried at
each level of production. All orders will be shipped on completion and the
maintenance of finished goods inventory will be the responsibility of NOVO
NORDISK. Upon ARADIGM's request, NOVO NORDISK will provide an update of current
inventory levels held in finished goods at all NOVO NORDISK or Affiliate
locations. Likewise, ARADIGM will upon NOVO NORDISK's request provide an update
of current inventory levels of raw materials for Devices and Packaged Product,
including inventory levels of Initial Compound. 

             (d)     NOVO NORDISK shall use diligent efforts to maintain
sufficient production capacity for Initial Compound and shall keep ARADIGM
informed of its plans for increasing capacity as necessary to meet the
requirements of ARADIGM for the production of Packaged Product.

             (e)     The parties will on a regular basis review long term market
forecasts generated by NOVO NORDISK in its normal internal planning cycle for
the purpose of anticipating the need for expanded production capacity in
sufficient time to develop and implement plans for such expansions.

        4.11 If the volume of Packaged Products containing Initial Compound
supplied to NOVO NORDISK exceeds [...***...], NOVO NORDISK shall have the right,
after consultation

with ARADIGM, to establish at its sole cost an additional site for manufacturing
such Packaged Products at an existing NOVO NORDISK site where insulin is already
being processed. In such case, ARADIGM may require that the key production
equipment installed at this site will be [...***...] and that the production
steps involving laser drilling will be maintained and performed by ARADIGM at An
existing or new ARADIGM facility. In such case, ARADIGM will supply [...***...]
to NOVO NORDISK on the teRMs specified in Article 4.5 and in other respects in a
manner that is equivalent to how it provides such [...***...] to its own
Packaged Product production facility, with allocations in the event of a
shortage to be made on a pro rata basis. NOVO NORDISK's license under Article
3.1 above shall be enlarged to include the right to make such Packaged Products
at such facility, and ARADIGM will provide NOVO NORDISK reasonable non-monetary
assistance in establishing such production facility. All costs directly related
to such assistance will be borne by NOVO NORDISK. NOVO NORDISK shall have the
right to [...***...], provided that ARADIGM shall have the right to implemEnt
such improvements in its own facilities and to otherwise use such improvements
outside the Field as well as in its own production of Packaged Products. NOVO
NORDISK acknowledges and agrees that this facility will be used to meet demand
for Packaged Products in excess of the threshold volumes required to trigger
NOVO NORDISK's right to establish such facility and that priority will be given
to maintaining the production levels of ARADIGM at or above such threshold
volumes in order to ensure that ARADIGM's production capacity is used
efficiently. ARADIGM shall continue to share in the Gross Profit associated with
Packaged Products produced in this facility as specified by Article 5 (with the
[...***...] of product produced at such facility to be included in the
calculatIon of Gross Profit). In the event the parties determine that additional
capacity beyond that which has been established by ARADIGM and by NOVO NORDISK
hereunder, such additional capacity will be planned and added on such basis as
the parties agree upon.

SECTION 5. -  LICENSE PAYMENTS AND PROFIT SHARING

        5.1 In consideration of the licence and marketing rights granted by
ARADIGM in accordance with Article 3 above, NOVO NORDISK shall pay to ARADIGM
the sum of USD two million (USD 2,000,000) within twenty (20) days after the
Effective Date. Such payment is non-refundable and will be in addition to, and
may not be applied toward or otherwise credited against, any other payment
required hereunder, including but not limited to the payments provided for in
Article 2.4.

        5.2 In addition to the payments referred to in Article 5.1 above, each
year during the term of this Agreement NOVO NORDISK shall pay to ARADIGM
[...***...] on Net Sales of the Packaged Products and the Devices during such
year; provided, however, that a different percentage may be applicable to
Packaged Products containing Other Compounds as agreed by the parties pursuant
to Article 2.1. Interim payments shall be made to ARADIGM during such year in
the form of a percentage of Net Sales of Packaged Products and Devices intended
to approximate ARADIGM's interest in the Gross Profit. The applicable interim
payment percentage shall be established by agreement of the parties at the
beginning of each calendar year to govern payments during such year and a
reconciliation account established and settled at the end of the year to achieve
the Gross Profit specified above. The interim payments above and the transfer

<PAGE>   18

price profit components referred to in Articles 4.5 and 4.6 shall be credited
against ARADIGM's share in t*he Gross Profit. 

        5.3 If the parties agree that it is necessary to enter into a Licence
Agreement with a third party to secure intellectual property rights in any
country in the Territory for the Packaged Products or the Device, [...***...].
Notwithstanding the foregoing, NOVO NORDISK shall bear all such costs that may
be payable in respect of any Programme Compound to secure freedom of operation
for that compound. 

        5.4 NOVO NORDISK shall keep complete and correct records of the Net
Sales of the Packaged Products and the Device and other financial information
necessary to determine the Gross Profit and shall report such information as is
pertinent along with each payment to ARADIGM. ARADIGM will maintain similar
records with respect to its pertinent costs hereunder. 

        5.5 Interim payments under Article 5.2 of this Agreement shall be due
and payable within [...***...] of each calendar year. To achieve a year-end
reconciliation, ARADIGM will provide NOVO NORDISK with [...***...] NOVO NORDISK
within thirty (30) days after receipt of ARADIGM's report or, if later, within
seventy-five (75) days after the end of the year. NOVO NORDISK shall pay or
ARADIGM shall refund, as applicable, any difference between interim payments
made and actual results within thirty (30) days after delivery of such
reconciliation report, subject to the audit rights of the parties. 

        5.6 Payments under this Agreement in respect of Net Sales made in
currencies other than USD shall be calculated on the average daily exchange rate
for the applicable year to date period (i.e., from January 1 of each year to the
last business day of the quarter in question) for exchanging the local currency
into USD at the rate for buying USD quoted by Den Danske Bank, and its
successor(s) in Copenhagen, Denmark. 

        5.7 Not more than once in a calendar year, at ARADIGM's request, NOVO
NORDISK agrees to provide to ARADIGM, at ARADIGM's expense, a statement from an
independent auditor selected by ARADIGM and reasonably acceptable to NOVO
NORDISK, attesting to the correctness of NOVO NORDISK's payments. In the event
such auditor determines that additional amounts are due to ARADIGM, such amounts
shall be promptly paid by NOVO NORDISK, together with the reasonable costs of
conducting the audit, it being understood that ARADIGM will otherwise bear such
audit costs. NOVO NORDISK shall likewise have the right to require an auditor's
statement as to the accuracy of the pertinent costs of ARADIGM. In the event
such auditor determines that additional amounts are due to NOVO NORDISK, such
amounts shall be promptly paid by ARADIGM, together with the reasonable costs of
conducting the audit, it being understood that NOVO NORDISK will otherwise bear
such audit costs. Notwithstanding the foregoing, relevant NOVO NORDISK personnel
shall once a year have a right to review with relevant ARADIGM personnel cost
and investment accounts related to activities under this Agreement. 

        5.8 NOVO NORDISK agrees to use Diligent Efforts to achieve commercial
success for the Packaged Products and the Device in each country in the
Territory in which Regulatory

Approval has been obtained, except for such countries in which it would not be
desirable to market such products in light of the overall commercialisation
strategy therefor. Prior to the initiation of Phase III clinical studies,
reasonably documented sales forecasts for such products for each of the United
States, the EEC and Japan for [...***...] following commercial launch will be
established. The initial [...***...] will be reviewed and approved by the
Steering Committee, provided that if the Steering Committee is unable to agree
on such forecast, the senior managements of the two parties will meet in an
effort to reach agreement. If agreement cannot be reached, NOVO NORDISK will
decide the matter. The initial sales forecasts for the EEC and Japan will be
established by NOVO NORDISK after review and comment by the Steering Committee.
Prior to First Marketing, NOVO NORDISK will update the [...***...] and review
and discuss wIth the Steering Committee the marketing plan by which it intends
to meet its marketing diligence obligation hereunder in respect of product
launch and during the first year after launch. At the end of the first and
second years following First Marketing, updated reasonably documented forecasts
for the [...***...] will be similaRly established and marketing plans will
likewise be reviewed and discussed. If NOVO NORDISK subsequently revises such
forecasts to less than [...***...] of initially forecasted levels for any year
or if actual results in any year are less than [...***...] of the [...***...]
for such year, NOVO NORDISK will develop and review with ARADIGM strAteGIES to
be implemented to ensure that the expected market potential will be realised.
The parties will also discuss the establishment of [...***...] and will likewise
in good faith discuss any failure or anticipated failure to achieve such minimum
pricing. If, notwithstanding such efforts, sales forecasts or actual sales
continue to be materially short of expectations or if pricing continues to be
below targeted minimums for more than a year, NOVO NORDISK agrees that upon
request by ARADIGM it will in good faith negotiate such modifications to this
Agreement or the Supply Agreement as may be reasonably necessary to enable
[...***...] in light of the scale of the forecasTed or actual commercial
results. Alternatively, NOVO NORDISK may at its election after such a
renegotiation request by ARADIGM elect to terminate this Agreement and the
Supply Agreement. At the end of each of the [...***...] commencing with the
third year following First Marketing, NOVO NORDISK will review and discuss its
latest reasonably documented [...***...] forecasts and marketing plans with
ARADIGM.

         ARADIGM agrees to use Diligent Efforts to realize its pre-Phase III
cost estimate contemplated by the Minimum Product Profile that is the basis for
a decision to proceed with Phase III trials. If, notwithstanding such efforts,
Aradigm's actual Fully Burdened Cost of producing Packaged Products (excluding
for these purposes the cost of the Initial Compound) and Devices are materially
higher than estimated (for reasons other than lower than expected volume or
externalities such as exchange rates or inflation) and as a result gross margins
contemplated by the Minimum Product Profile are not achieved, ARADIGM will
develop and review with NOVO NORDISK strategies to be implemented to reduce
costs to targeted levels. If, notwithstanding such efforts, ARADIGM costs
continue to be materially higher than targeted levels for more than a year, then
ARADIGM agrees that upon request by NOVO NORDISK it will in good faith negotiate
such modifications to this Agreement or the Supply Agreement as may be
reasonably necessary to enable NOVO NORDISK to realise a reasonable profit on
its sales of Packaged Products and Devices. In no event will NOVO NORDISK be
under any obligation to agree to pay ARADIGM Fully Burdened Cost amounts for
Packaged Products and

Devices that do not enable a Gross Profit Margin of at least 70%. Alternatively,
ARADIGM may at its election after such a renegotiation request by NOVO NORDISK
elect to terminate this Agreement and the Supply Agreement. Notwithstanding the
foregoing, if in either of the above situations a party requests a renegotiation
of the terms of the Agreement or the Supply Agreement, it is expressly
understood that neither party will be required to agree to any terms that do not
enable it to realise a reasonable profit on its activities under this Agreement
and the Supply Agreement, it being further understood that the parties
anticipate a termination of this Agreement and the Supply Agreement if it is not
possible for both parties to realise a reasonable profit.

        5.9 Under no circumstances shall NOVO NORDISK be required to pay any
amount in excess of or in addition to the payments agreed under this Agreement.
If any payment made by NOVO NORDISK under this Agreement is subject to
withholding tax, such withholding tax shall be borne by ARADIGM and shall be
deducted from the payments made by NOVO NORDISK. Upon ARADIGM's written request,
NOVO NORDISK shall support ARADIGM in its efforts of minimizing any such
withholding taxes, and reasonably provide ARADIGM with relevant information
about documentation needed to reduce the withholding tax to a legal minimum or
to secure applicable credits in respect thereof.

SECTION 6.  -  INTELLECTUAL PROPERTY

        6.1 ARADIGM shall remain the sole owner of all ARADIGM Patent Rights and
ARADIGM Know-How obtained by ARADIGM individually prior to entering into this

improvements or inventions ("ARADIGM Programme Inventions") whether patentable
or not made jointly by the parties or individually by one of the parties as a
part of the Development Programme during the term of this Agreement and which
relate solely to [...***...]. ARADIGM shall be responsible for filing,
maintaining and defending any patents filed based on ARADIGM Programme
Inventions and will timely inform NOVO NORDISK of its intentions, activities and
filings in this respect. ARADIGM will grant NOVO NORDISK a royalty free license,
with the right to sublicense, under the ARADIGM Programme Inventions. Such
license will be perpetual but will be limited to applications [...***...]. (b)
Should ARADIGM decide not to patent an ARADIGM Programme Invention in any
country, NOVO NORDISK shall have the right to do so. In such case, NOVO NORDISK
shall be the owner of any patent or patent application based on such ARADIGM
Programme Invention and will grant ARADIGM a royalty free licence thereunder,
with the right to sublicence. Such licence will be for the life of the patent

with respect to specified Packaged Products, to applications other than those
for which there is continuing exclusivity under Article 3.3). Should ARADIGM
decide to abandon any such patent or patent application, in any country, NOVO
NORDISK shall have the option to take over such patent or patent application. In
such case, NOVO NORDISK shall be the owner thereof and will grant ARADIGM a
royalty free licence thereunder, with the right to sublicence. Such licence will

thereafter for sO long as NOVO NORDISK retains exclusivity under Article 3.3
with respect to specified Packaged Products, to applications other than those
for which there is continuing exclusivity under Article 3.3). (c) Furthermore,
NOVO NORDISK shall be entitled to enter any litigation in the defence and
enforcement of any such patents by any infringer thereof in the Field and the
parties shall agree in good faith regarding any such defence and enforcement, as
well as how to pay for any costs incurred and how to share any rewards. 

        6.4 (a) NOVO NORDISK shall retain ownership of any and all results,
improvements or inventions whether patentable or not made jointly by the parties
or individually by one of the parties as a part of the Development Programme
during the term of this Agreement and which relate solely to [...***...].
Inventions relating to the Formulated Compound owned by NOVO NORDISK are
referred to as "NOVO Formulation Inventions." NOVO NORDISK shall be responsible
for filing, maintaining and defending any patents filed based on NOVO
Formulation Inventions and will timely inform ARADIGM of its intentions,
activities and filings in this respect. NOVO NORDISK will grant ARADIGM a
royalty free licence, with the right to sublicence, under the NOVO Formulation
Inventions. Such licence will be perpetual but will be limited to applications
[...***...]. (b) Should NOVO NORDISK decide not to patent a NOVO Formulation

ARADIGM shall be the owner of any patent or patent application based on such
NOVO Formulation Invention and will grant NOVO NORDISK a royalty free licence
thereunder, with the right to sublicence, for the life of the patent. Should
NOVO NORDISK decide to abandon any such patent or patent application, in any
country, ARADIGM shall have the option to take over such patent or patent
application. In such case, ARADIGM shall be the owner of such patent or patent
application and will grant NOVO NORDISK a royalty free licence thereunder, with
the right to sublicence, for the life of the patent. (c) Furthermore, ARADIGM
shall be entitled to enter any litigation in the defence and enforcement of any
such patents by any infringer thereof [...***...] and the parties shall agree in
good faith regarding any such defence and enforcement, as well as how to pay for
any costs incurred and how to share any reward. 

        6.5 The foregoing is not intended to limit in any respect the rights of
ARADIGM under Articles 3.3, 9.3 and 9.5 to develop and commercialise Devices and
Packaged Products under the circumstances specified therein. NOVO NORDISK will
grant ARADIGM a perpetual royalty free licence, with the right to sublicence,
[...***...] utilized in the Development Programme needed by ARADIGM in order
only to conduct and continue the development, production and commercialisation
activities contemplated by Article 3.3, 9.3 and 9.5 of this Agreement.
