                              CONNETICS CORPORATION
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                 MARCH 31, 2000
                                   (UNAUDITED)

1.      BASIS OF PRESENTATION
        We have prepared the accompanying unaudited condensed consolidated
financial statements of Connetics Corporation ("Connetics") in accordance with
generally accepted accounting principles for interim financial information and
pursuant to the instructions to Form 10-Q and Article 10 of Regulation S-X.
Accordingly, the financial statements do not include all of the information and
footnotes required by generally accepted accounting principles for complete
financial statements. In our opinion, all adjustments, consisting of normal
recurring accrual adjustments, considered necessary for a fair presentation have
been included. Operating results for the three month period ended March 31, 2000
are not necessarily indicative of the results that may be expected for the year
ending December 31, 2000.

        These financial statements and notes should be read in conjunction with
audited financial statements and notes to those financial statements for the
year ended December 31, 1999 included in our Annual Report on Form 10-K.


2.      EARNINGS PER SHARE
        We compute basic earnings per share based on the weighted average number
of common shares outstanding during the period. Diluted earnings per share also
includes the incremental shares expected to be issued pursuant to the exercise
of in-the-money stock options and other potentially dilutive securities. The
number of incremental shares from the assumed issuance of stock options and
other potentially dilutive securities is calculated applying the treasury stock
method. Common stock equivalent shares are excluded from the computation when
there is a loss, as their effect is anti-dilutive. The following table sets
forth the computations for basic and diluted earnings per share.

Accumulated other comprehensive income at March 31, 2000 and December 31, 1999
consisted of unrealized gains on securities of $21.0 million and $ 0.1 million,
respectively.

4.      RESEARCH AND LICENSE AGREEMENTS
        In January 1999, Connetics entered into a development, commercialization
and supply agreement with Celltech Group, PLC (formerly Medeva PLC) of the
United Kingdom ("Celltech)") for certain therapeutic indications pertaining to
relaxin. Under the terms of the agreement, Medeva paid $8.0 million upon
closing, which included a $4.0 million contract fee and a $4.0 million equity
investment, and will potentially pay $17.0 million of milestone payments based
upon the achievement of development milestones in the U.S. and Europe and $5.0
million for the development and approval of each indication in Europe in
addition to scleroderma. Celltech is responsible for all development and
commercialization activities in Europe and is required to pay royalties on sales
in Europe. In addition, Celltech will reimburse us for 50% of the product
development costs in the U.S. up to a maximum of $1.0 million per quarter, for
an estimated total of $10.0 million. We also agreed to potentially share U.S.
co-promotion rights with Celltech for up to five years, and Celltech will
purchase relaxin materials from us. We recorded $6.0 million for the quarter
ended March 31, 2000, and $5.0 million for the quarter ended March 31, 1999, in
contract revenue under this agreement.

        In July 1999, we entered into a development, commercialization and
supply agreement with Paladin Labs Inc., a Canadian corporation, for relaxin.
Under the terms of the agreement, Paladin will pay up to $3.2 million in
development, milestone and equity payments for the successful development of
Relaxin for the treatment of scleroderma. We may receive additional milestone
payments for the approval of additional indications for relaxin in Canada.
Paladin is responsible for all development and commercialization activities in
Canada, and will pay royalties on all sales of relaxin in Canada. For the three
months ended March 31, 2000, we recorded $0.2 million in contract revenue under
this agreement.

5.      INTERMUNE

        On April 28, 1999, our wholly-owned subsidiary InterMune became an
independent company through venture capital funding and a portion of our
original investment in InterMune was returned to us. We established InterMune to
develop Actimmune for serious pulmonary and infectious diseases and congenital
disorders shortly after we in-licensed Actimmune from Genentech in May 1998. We
retained approximately a 10% equity position in InterMune, which is now
approximately a 7% equity position, received a license fee payment of $500,000,
a $4.7 million return of invested capital, and will receive an additional return
of invested capital of $3.5 million in the form of cash and equity receivable
through fiscal 2001, of which we received $1.5 million in cash during the first
quarter of 2000. We have retained commercial rights to and revenue from
Actimmune for chronic granulomatous disease up to a predetermined annual
baseline that is preset for three years (January 15, 1999 through December 31,
2001) and will receive a royalty on Actimmune sales thereafter. In addition, we
have retained the product rights for potential dermatological applications of
Actimmune. During the first quarter of 2000, Intermune completed its initial
public offering, and as a result, we recorded a mark-to-market unrealized gain
of $20.4 million on our equity investment. The Intermune investment is included
in non current marketable securities in the Condensed Consolidated Balance Sheet
at March 31, 2000.

6.      LIQUIDITY AND FINANCIAL VIABILITY
        In the course of our development activities, we have sustained
continuing operating losses and expect such losses to continue for the next few
years. Our future capital uses and requirements depend on numerous factors,
including the progress of our research and development programs, the progress of
clinical testing, the time and costs involved in obtaining regulatory approvals,
the cost of filing, prosecuting, and enforcing patent claims and other
intellectual property rights, competing technological and market developments,
our ability to establish collaborative arrangements, the level of product
revenues, the possible acquisition of new products and technologies, and the
development of commercialization activities. Therefore, such capital uses and
requirements may increase in future periods. As a result, we may require
additional funds prior to reaching profitability and may attempt to raise
additional funds through equity or debt financings, collaborative arrangements
with corporate partners or from other sources. Our inability to obtain
sufficient funds could require us to delay, scale back or eliminate some or all
of our research and development programs, to limit the marketing of our
products, or to license to third parties the rights to commercialize products or
technologies that we would otherwise seek to develop and market ourselves.

7.      REVENUE RECOGNITION
When we receive non-refundable fees in connection with collaborative agreements,
we have recognized the fees as revenue when received, when the technology has
been transferred and when all of our contractual obligations relating to the
fees had been fulfilled. In December 1999, the Securities and Exchange
Commission issued Staff Accounting Bulletin No. 101 - Revenue Recognition in
Financial Statements (SAB 101). SAB 101 describes the SEC Staff's position on
the recognition of certain non-refundable upfront fees received in connection
with research collaborations. We are currently evaluating the applicability of
SAB 101 to our existing collaborative agreements. Should we conclude that the
approach described in SAB 101 is more


                                      -8-
<PAGE>   9

appropriate, we will change our method of accounting effective January 1, 2000
to recognize such fees over the term of the related agreement. If we make this
change in accounting principle, the cumulative effect would be recognized in the
year to date presentation for the quarter ending June 30, 2000. The cumulative
effect, if any, would be recorded as deferred revenue and would be recognized as
revenue over the remaining term of the respective collaborative research and
development agreements.

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

        This MD&A should be read in conjunction with the MD&A included in our
Annual Report on Form 10-K for the year ended December 31, 1999, and with the
unaudited condensed consolidated financial statements and notes to financial
statements included in this report. Except for historical information, the
discussion in this report contains forward-looking statements that involve risks
and uncertainties. When used in this report, the words "anticipate," "believe,"
"estimate," "will," "intend" and "expect" and similar expressions identify
forward-looking statements. Although we believe that our plans, intentions and
expectations reflected in these forward-looking statements are reasonable, these
plans, intentions, or expectations may not be achieved. Some of the factors
which, in our view, could cause actual results to differ are discussed under the
caption "Factors That May Affect Future-Results, Financial Condition and the
Market Price of Securities" and in our Annual Report on Form 10-K. Our
historical operating results are not necessarily indicative of the results to be
expected in any future period.

OVERVIEW

        We are currently developing Relaxin for the treatment of scleroderma,
infertility, peripheral arterial disease and organ fibrosis. We have completed
enrollment in a pivotal clinical trial for scleroderma, and we have two Phase
I/II clinical trials ongoing for infertility. In February, we filed an
investigational new drug application to initiate trials in peripheral arterial
disease. In our dermatology business, we received marketing clearance from the
U.S. Food and Drug Administration (FDA) in March 1999 to sell Luxiq
(betamethasone valerate) Foam, 0.12%, for the treatment of steroid responsive
scalp dermatoses. Our principal dermatology product under development is OLUX
Foam (clobetasol propionate) 0.05%, for the treatment of moderate to severe
scalp dermatoses, for which we submitted an NDA in July 1999. We also market
Ridaura (auranofin), a treatment for rheumatoid arthritis, and Actimmune
(interferon gamma) for the treatment of chronic granulomatous disease (through
licensing arrangements with Genentech and InterMune).

        Our product revenues for the quarter ended March 31, 2000 were $5.7
million, representing a 162% increase over revenues of $2.2 million for the same
period in 1999. The increase in total product sales was due to sales of Luxiq,
which was launched in April 1999, and sales growth for Actimune. Although
Ridaura sales increased quarter over quarter, we believe that Ridaura will
experience decreased sales for the remainder of 2000 due to competition from new
and existing products.

        Contract revenues for the quarter ended March 31, 2000 were $7.8 million
which includes a one-time $5 million payment from Celltech in connection with
our agreement for the development of Relaxin. In addition, we recorded $1.5
million in revenue in connection with our sublicense agreement with InterMune.
We expect contract revenue to fluctuate significantly depending on when and
whether we or our partners achieve milestones under existing agreements, and on
new business opportunities that we may identify.

        Our cost of product revenues includes the costs of Luxiq, Ridaura and
Actimmune, royalty payments on these products based on a percentage of our
product revenues, and product freight and distribution costs from CORD. For the
quarter ended March 31, 2000, we recorded cost of product revenues of $1.8
million compared to $1.2 million for the same period in 1999. The increase in
cost of product revenues in the first quarter of 2000 over the first quarter of
1999 is primarily due to costs associated with the sales of Luxiq and Actimmune,
which we began shipping in 1999, and higher product and royalty costs. In the
first quarter of 1999, we recorded $1.7 million of amortization expense
associated with the acquisition of product rights to Ridaura.


    RESEARCH AND DEVELOPMENT

        Research and development expenses were $6.1 million for the three months
ended March 31, 2000 compared to $4.7 million for the same period in 1999. The
increase in research and development expenses quarter over quarter was due to:

        o manufacturing scale-up of Relaxin;
        o conducting a Phase II/III trial of Relaxin for the treatment of
          scleroderma;
        o increasing personnel in our development organization; and
        o initiating of clinical trials of Relaxin for the treatment of
          infertility.

        We expect research and development expenses to remain at the same level
for the next few quarters, due to scale-up expenses related to Relaxin
manufacturing, Relaxin clinical trial activities for new disease indications,
and preclinical activities associated with technologies acquired from Soltec.

    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES

        Selling, general and administrative expenses were $5.5 million for the
quarter ended March 31, 2000 compared to $5.6 million for the same period in
1999. We expect selling, general and administrative expenses to remain flat or
increase slightly during the remainder of fiscal 2000.

        INTEREST INCOME (EXPENSE)

        Interest income was $0.7 million in the three months ended March 31,
2000, compared with $0.3 million for the same period in 1999. The increase in
interest income quarter over quarter was due to a higher investment balance as a
result of proceeds received through a public offering of our common stock in
October 1999 and funds received from corporate partnership arrangements.
Interest earned in the future will depend on our funding cycles and prevailing
interest rates. Interest expense decreased to $0.1 million for the three months
ended March 31, 2000, compared with $0.3 million for the same period in 1999.
The decrease in interest expense quarter over quarter was due to:

     o  lower imputed interest expense attributable to the non-interest bearing
        promissory note payable to SmithKline in connection with the acquisition
        of Ridaura; and
     o  lower balances outstanding for obligations under capital leases and
        loans, and notes payable


    NET INCOME (LOSS)

        Net income for the three months ended March 31, 2000 was $0.6 million
compared to a net loss $5.9 million for the same period in 1999. The net income
for the first quarter of 2000 was attributable to increased revenues and
included:

    o   a one-time $5 million contract payment from Celltech in connection with
        our agreement for the development of Relaxin; and
    o   contract payment of $1.5 million in connection with our Amended and
        Restated Exclusive Sublicense Agreement with InterMune.
    o   product revenue increase of 162% or $3.5 million quarter over quarter.

        We expect to incur losses for the remainder of 2000 and the foreseeable
future. These losses are expected to fluctuate from period to period based on
timing of product revenues, clinical material purchases, clinical trial
expenses, and possible acquisitions of new products and technologies.


LIQUIDITY AND CAPITAL RESOURCES

        We have financed our operations to date primarily through proceeds from
equity financings, collaborative arrangements with corporate partners, and bank
loans. At March 31, 2000, cash, cash equivalents and short-term investments
totaled $24.9 million compared to $26.3 million at December 31, 1999. During the
first quarter of 2000, we recorded an unrealized gain of $20.4 million on our
equity investment in InterMune. The InterMune investment is included in other
non-current assets. Our cash reserves are held in a variety of interest-bearing
instruments including high-grade corporate bonds, commercial paper and money
market accounts.

Cash flows from operating activity. Cash used in operations for the three month
periods ended March 31, 2000, and March 31, 1999, was $1.4 million and $1.4
million, respectively. Net income of $0.6 million for the first quarter of 2000
was affected by non-cash charges including $0.7 million of variable option
expense. Cash outflow for the first quarter of 2000 was


                                      -12-
<PAGE>   13

primarily for operating activities which included a $2.0 million and $2.2
million reduction in accounts payable and accrued process development expense,
respectively, partially offset by a lower accounts receivable balance.

        Cash flows from investing activity. Investing activities provided $5.4
million in cash during the three month period ended March 31, 2000, due to the
sale of $7.0 million of short-term investments partially offset by $1.5 million
of short term investment purchases.

        Cash flows from financing activity. Cash provided by financing
activities for the three months ended March 31, 2000 included $1.2 million of
cash proceeds from the issuance of stock, offset by $1.1 million of note and
lease payments.

        Working Capital. Working capital increased by $2.1 million to $15.5
million at March 31, 2000 from $13.4 million at December 31, 1999. The increase
in working capital was due to lower accounts payable and accrued liabilities
balances partially offset by cash used for operations.

        At March 31, 2000, we had an aggregate of $3.7 million in future
obligations of principal payments under capital leases, loans, long-term debt
and other obligations, of which $3.1 million is to be paid within the next year.

        We have an equity line agreement with an investor, Kepler, that may
potentially provide access to capital through sales of our common stock. The
equity line expires in December 2000. Until then, when our stock meets certain
minimum trading volume requirements and trades above $10.00 per share, then the
investor may require us to draw up to $500,000 against the equity line
approximately every three months in exchange for the sale of stock at a discount
to the market price. During the first quarter of 2000, our stock traded over
$10.00 per share for the first time since the Equity Line Agreement became
available in December 1997. Consequently, Kepler exercised its right to draw
down $500,000 against the equity line in exchange for our common stock, and we
issued 58,438 shares to Kepler at a purchase price of $8.556 on February 10,
2000. We also have the right to draw down on the equity line in exchange for the
sale of stock, beyond the $500,000 minimum investment each quarter, provided our
stock trades above $7.00 per share.

        We believe our existing cash, cash equivalents and short-term
investments, cash generated from product sales and collaborative arrangements
with corporate partners, will be sufficient to fund our operating expenses, debt
obligations and capital requirements through at least the next 12 months. Our
future capital uses and requirements depend on numerous factors, including the
progress of our research and development programs, the progress of clinical
testing, the time and costs involved in obtaining regulatory approvals, the cost
of filing, prosecuting, and enforcing patent claims and other intellectual
property rights, competing technological and market developments, our ability to
establish other collaborative arrangements, the level of product revenues, the
possible acquisition of new products and technologies and the development of
commercialization activities. Therefore such capital uses and requirements may
increase in future periods. As a result, we may require additional funds before
we become profitable and may attempt to raise additional funds through equity or
debt financings, collaborative arrangements with corporate partners or from
other sources.

        Other than the equity line agreement discussed above, we currently have
no commitments for any additional financings, and there can be no assurance that
additional funding will be


                                      -13-
<PAGE>   14

available to finance our ongoing operations when needed or, if available, that
the terms for obtaining such funds will be favorable or will not result in
dilution to our stockholders. Our inability to obtain sufficient funds could
require us to delay, scale back or eliminate some or all of our research and
development programs, to limit the marketing of our products or to license to
third parties the rights to commercialize products or technologies that we would
otherwise seek to develop and market ourselves.

YEAR 2000 COMPLIANCE

        As of May 8, 2000, we had not experienced, nor do we expect to
experience, any Year 2000-related disruption in the operation of our systems. To
our knowledge, none of our material suppliers or customers experienced any
material Year 2000 problems or had any difficulty resolving the so-called
"century leap year" algorithm. Although most Year 2000 problems should have
become evident on January 1, 2000 or February 29, 2000, additional Year
2000-related problems may become evident in the future.

FACTORS THAT MAY AFFECT FUTURE RESULTS, FINANCIAL CONDITION AND THE MARKET PRICE
OF SECURITIES

       Please also read Items 1 and 3 in our 1999 Annual Report and Form 10-K
where we have described our business and the challenges and risks we may face in
the future.

        Our results of operations have varied widely in the past, and they could
continue to vary significantly from quarter to quarter due to a number of
factors, including those listed below. Any shortfall in revenues would have an
immediate impact on our earnings per share, which could adversely affect the
market price of our common stock. Our operating expenses, which include sales
and marketing, research and development and general and administrative expenses,
are based on our expectations of future revenues and are relatively fixed in the
short term. Accordingly, if revenues fall below our expectations, we will not be
able to reduce our spending rapidly in response to such a shortfall. This will
adversely affect our operating results. Due to the foregoing factors, we believe
that quarter-to-quarter comparisons of our results of operations are not a good
indication of our future performance.

RISKS RELATED TO OUR BUSINESS

If we do not obtain the capital necessary to fund our operations, we wil be
unable to develop or market our products.

    We believe that our available cash resources will be sufficient to fund our
operating and working capital requirements for the next 12 months. Accordingly,
we may need to raise additional funding in the future. In particular, if our
ConXn clinical trial is successful, our working capital needs will increase as
we will incur additional regulatory and commercialization expenses for ConXn. In
this event, we would need to raise additional funds. If we are unable to raise
additional funds when needed, we may not be able to market our products as
planned, or continue development of our other products.

        We may need to raise additional funds through public or private
financings, strategic relationships or other arrangements. In particular, if our
ConXn clinical trial for scleroderma is successful, we would incur significant
additional expenditures associated with pursuing regulatory approval and
eventual commercialization of ConXn which would extend the date as of


                                      -14-
<PAGE>   15

which we could first achieve profitability. If we are unable to successfully
complete development and commercialization of ConXn, we may never achieve
profitability. If we need to raise additional money to fund our operations,
funding may not be available to us on acceptable terms, or at all.

Fluctuations in our operating results may cause our stock price to decline.

    Our quarterly and annual operating results are difficult to predict and may
fluctuate significantly from time to time and may not meet the expectations of
securities analysts and investors in some future period. As a result, the price
of our common stock could decline.

We have a history of losses, we expect to incur losses in the future, and we may
not be able to achieve or sustain profitability, which may cause our stock price
to decline.

    We have lost money every year since our inception. We had net losses of
$26.6 million in 1998 and $27.3 million 1999. Our accumulated deficit was $119.8
million at December 31, 1999. We expect to incur additional losses for at least
the next few years. We may not achieve profitability and, if we do reach
profitability, we may not be able to sustain it. Our ability to reach and
sustain profitability will depend upon the success of our current products and
our products under development.

If our corporate partners are no longer willing or able to fund the development
of ConXn, our current product revenue will not cover the cost of fully
developing and commercializing ConXn.

    We depend on licensing agreements with our corporate partners to
successfully develop and commercialize our products. We also generate revenue by
licensing our products to third parties for specific territories and
indications. Our reliance on third parties for our success carries several
risks, including the possibilities that:

    o   a product development contract may expire or a relationship may be
        terminated, and we will not be able to attract a satisfactory
        alternative corporate partner within a reasonable time;

    o   a corporate partner involved in the development of our products does
        not commit sufficient capital to successfully develop our products; and

    o   we may be contractually bound to terms that, in the future, are not
        commercially favorable to us.

If any of these risks occurs, we may not be able to successfully develop our
products at the rate we anticipate, or we may not be able to develop them at
all.

If we fail to protect our proprietary rights, competitors may be able to use our
technologies, which would weaken our competitive position, reduce our revenues
and increase our costs.

    Our commercial success depends in part on our ability and the ability of our
licensors to protect our technology and processes.



                                      -15-
<PAGE>   16

    The foam technology used in our Luxiq and OLUX products is not covered by
issued patents but is the subject of pending patent applications. If we do not
obtain patent coverage for Luxiq and OLUX, it may be easier and more attractive
for potential new market entrants to develop and introduce competitive products.

    With regard to patent applications that we or our licensors have filed, or
patents issued to us or our licensors:

      -     any pending patent applications may not issue as patents;
      -     our competitors may successfully challenge or circumvent our
            patents; or
      -     any patents which exist or are issued may not provide us with a
            competitive advantage.

    In addition, others may obtain patents that contain claims which cover
products or processes that we make, have made, use, or sell. If a third party
claimed an intellectual property right to technology we use, we might be forced
to discontinue an important product or product line; alter our products or
processes to avoid infringement; pay license fees and/or damages; and cease
certain activities.

    Under these circumstances, we may not be able to obtain a license to such
intellectual property on favorable terms, if at all. We may not succeed in any
attempt to redesign our products or processes to avoid infringement.

    A judgment adverse to us in any patent interference, litigation or other
proceeding arising in connection with these patent applications could materially
harm our business. In addition, the costs of any such proceeding may be
substantial whether or not we are successful.

We depend on third parties to protect and maintain our patent portfolio.

    Nearly our entire patent portfolio is licensed from third parties, who are
responsible to varying degrees for the prosecution and maintenance of those
patents. Our success will depend on our ability, or the ability of our
licensors, to obtain and maintain patent protection on technologies, to preserve
trade secrets, and to operate without infringing the proprietary rights of
others. It is possible that before any of our products in development can be
commercialized, the related patents may have expired or be close to expiration,
thus reducing any advantage of the patent. Moreover, composition of matter
patent protection, which gives patent protection for a compound or a
composition, may not be available for some of our product candidates.

    The patents licensed to us, if challenged, may not be upheld. In addition,
the patents in our relaxin patent portfolio begin to expire in 2002 in foreign
countries and 2005 in the United States. Additional patents may not issue, and
if they do, they may not be sufficient to protect our relaxin products.

If we do not successfully commercialize relaxin, we may lose fundamental
intellectual property rights to the product.

    Licenses with Genentech and the Florey Institute require us to use our best
efforts to commercialize relaxin. Our failure to successfully commercialize
relaxin may result in the reversion of our rights under these licenses to
Genentech and the Florey Institute. The termination of these agreements and
subsequent reversion of rights could cause us to lose fundamental intellectual
property rights to relaxin. This would prohibit us from continuing our


                                      -16-
<PAGE>   17

relaxin development programs, which would seriously harm our business and our
future prospects.

We are subject to foreign exchange risks which may increase our operational
expenses.

    We make payments to Boehringer Ingelheim for the production of ConXn in
Austrian schillings, and to CCL Pharmaceuticals for the production of Luxiq and
OLUX in pounds sterling. If the U.S. dollar depreciates against the schilling or
the pound, the payments that we must make will increase, which may harm our
financial condition.

Our use of hazardous materials exposes us to the risk of environmental
liabilities, and we may incur substantial additional costs to comply with
environmental laws.

    Our research and development activities involve the controlled use of
hazardous materials, chemicals and various radioactive materials. We are subject
to federal, state and local laws and regulations governing the use, storage,
handling and disposal of these materials and certain waste products. We cannot
completely eliminate the risk of accidental contamination or injury from these
materials. In the event of such an accident, we could be liable for any damages
that result and any liability could exceed our resources. We could be required
to incur significant costs to comply with environmental laws and regulations as
our research activities increase.

RISKS RELATED TO OUR PRODUCTS

If ConXn fails in its clinical trials for the treatment of scleroderma, we will
not be able to market ConXn for that disease.

    ConXn, the recombinant human relaxin product that we are developing, is
critical to our future success. We are initially studying ConXn for the
treatment of diffuse scleroderma, a serious disease involving the excessive
formation of connective tissue. We initiated a pivotal Phase II/III trial of
ConXn for the treatment of diffuse scleroderma in February 1999, and completed
patient enrollment in that trial in December 1999. To complete the development
of ConXn for scleroderma, we will need, at a minimum, to demonstrate the safety
and efficacy of ConXn in this clinical study; and submit a biologics license
application to the FDA for the purpose of obtaining approval to market ConXn in
the United States.

    The current ConXn clinical trial may not be successful and we may not be
able to submit a biologics license application for ConXn. Even if the clinical
data support the submission of a biologics license application, the FDA may not
approve this application for the indications for which we submit. Furthermore,
we may encounter unforeseen delays in the regulatory approval process.

If our clinical trials fail to demonstrate that our products are safe and
effective for the treatment of the diseases we are targeting, the FDA will not
permit us to market our products for those diseases.

    Our current trials or future clinical trials may not demonstrate the safety
and efficacy of any products and may not result in approval to market products.
The results from preclinical studies and early clinical trials may not be
predictive of results that will be obtained in later-stage testing. Many
companies in the pharmaceutical and biotechnology industries have suffered
significant setbacks in advanced clinical trials, even after promising results
from earlier trials.



                                      -17-
<PAGE>   18

    In addition to the clinical trial for scleroderma, we are in earlier stages
of development of ConXn for other indications, including infertility and
peripheral arterial disease. Even if ConXn is successful in the treatment of
scleroderma, the long-term potential of ConXn rests with other indications, such
as the ones we are studying. For ConXn to succeed, we will need, at a minimum,
to demonstrate the safety and efficacy of ConXn in these clinical studies, and
apply to the FDA to enter into pivotal trials for these indications in the
United States.

    In addition to ConXn, we have a pipeline of potential products that are all
subject to FDA review. Before any company can obtain regulatory approval for the
commercial sale of its products under development, it must demonstrate through
preclinical studies and clinical trials that the product is safe and effective
for use in the target indication for which approval is sought. The results from
preclinical studies and early clinical trials may not be predictive of results
that will be obtained in later-stage testing, and future clinical trials may not
demonstrate the safety and efficacy of any products and may not result in
approval to market products. Furthermore, we may encounter unforeseen delays in
the regulatory approval process. If we are unable to commence clinical trials as
planned, enroll sufficient patients in our clinical trials, complete the
clinical trials, or demonstrate the safety and efficacy of our products, our
business will be harmed. Even if a product from our research and development
programs performs favorably in clinical trials, the FDA may not approve it.

If Luxiq and OLUX do not achieve or sustain market acceptance, our revenues will
not increase and may not cover our operating expenses.

    Our future revenues will depend upon dermatologist and patient acceptance of
Luxiq, and OLUX if it receives regulatory clearance. Factors that could affect
acceptance of Luxiq and OLUX include:

      o     satisfaction with existing alternative therapies; ~
      o     the effectiveness of our sales and marketing efforts;
      o     undesirable and unforeseeable side effects; and
      o     the cost of the product as compared with alternative therapies.

    Since we have only had approval to sell Luxiq for one year, the potential
long-term patient acceptance of the product is uncertain. OLUX must receive FDA
clearance before we can sell in the United States, and we will be unable to
begin to assess acceptance of OLUX until we begin commercial sales.

If we are unable to develop alternative delivery systems for ConXn, patients
that do not suffer from severe diseases may not be willing to use the current
drug delivery system.

    In addition to demonstrating the safety and efficacy of ConXn in our current
clinical trials, we must meet several additional major development objectives
for ConXn. In particular, we may need to develop an alternative means of
delivering the drug. In our current clinical trials, ConXn is being delivered
through the use of an infusion pump. For a serious and life threatening
condition, such as diffuse scleroderma, this method of delivery may be
acceptable. However, we are pursuing other indications for ConXn, such as
treatment of infertility and peripheral vascular disease. For these indications,
we may need to develop an alternative delivery system; however, the known
biological properties of the relaxin molecule may decrease the availability of
certain



                                      -18-
<PAGE>   19

delivery systems. If we are not able to develop a suitable alternative delivery
system for ConXn, we may not be unable to market ConXn effectively for
indications that are not life threatening, such as infertility, and the
commercial potential of ConXn would be seriously harmed. Our inability to
develop ConXn to its full commercial potential would harm our future prospects
and revenue growth and our stock price would likely decline.

We rely on third parties to conduct clinical trials for our products, and those
third parties may not perform satisfactorily.

    We do not have the ability to independently conduct clinical studies, and we
rely on third parties to perform this function. If these third parties do not
perform satisfactorily, we may not be able to locate acceptable replacements or
enter into favorable agreements with them, if at all. If we are unable to rely
on clinical data collected by others, we could be required to repeat clinical
trials, which could significantly delay commercialization and require
significantly greater capital.

If we cannot maintain our regulatory approvals, we will be unable to sell our
products for their intended diseases.

    The process of obtaining and maintaining regulatory approvals for
pharmaceutical and biological drug products, and obtaining and maintaining
regulatory approvals to market these products for new indications, is lengthy,
expensive and uncertain. The manufacturing and marketing of drugs are subject to
continuing FDA and foreign regulatory review, and later discovery of previously
unknown problems with a product, manufacturing process or facility may result in
restrictions, including withdrawal of the product from the market.

        If we get approval, whether in the United States or internationally, we
will continue to be subject to extensive regulatory requirements. If we fail to
comply or maintain compliance with such laws and regulations, we may be fined
and barred from selling our products. In addition, governmental authorities
could seize our inventory of products or force us to recall our products already
in the market if we fail to comply with FDA regulations.

Manufacturing difficulties could delay commercialization of our products.

    We depend on third parties to manufacture our products and each product is
manufactured by a sole source manufacturer. These parties must comply with the
applicable FDA good manufacturing practice regulations, which include quality
control and quality assurance requirements as well as the corresponding
maintenance of records and documentation. Manufacturing facilities are subject
to ongoing periodic inspection by the FDA and corresponding state agencies,
including unannounced inspections, and must be licensed before they can be used
in commercial manufacturing of our products. If our sole source manufacturers
cannot provide us with our product requirements in a timely and cost-effective
manner, or if the product they are able to supply cannot meet commercial
requirements for shelf life, or if they are not able to comply with the
applicable good manufacturing practice regulations and other FDA regulatory
requirements, our sales of marketed products could be reduced and we could
suffer delays in the progress of clinical trials for products under development.
We do not have control over our third-party manufacturers' compliance with these
regulations and standards. CCL will need to pass an FDA inspection before we can
be approved to sell OLUX. The fact that a facility has passed inspection in the
past does not guarantee that it will pass future inspections.


                                      -19-
<PAGE>   20

If we are unable to contract with third parties to manufacture and distribute
our products in sufficient quantities, on a timely basis, or at an acceptable
cost, we may be unable to meet demand for our products and may lose potential
revenues.

    We have no manufacturing or distribution facilities for any of our products.
Instead, we contract with third parties to manufacture our products for us. If
these third parties are unable or unwilling to produce our products in
sufficient quantities, with appropriate quality for our clinical trials and
subsequent commercialization, if any, and under commercially reasonably terms,
our business will suffer.

    In addition, we have entered into an agreement with CORD Logistics, Inc. to
distribute Luxiq, Ridaura and Actimmune. CORD's inability to continue to
distribute our products in an effective manner or our inability to maintain
sufficient personnel with the appropriate levels of experience to manage this
function would seriously harm our business.


RISKS RELATED TO OUR INDUSTRY

If we do not obtain governmental approvals for our products in development, we
cannot sell these products.

    All of our products under development must be approved by the FDA before we
are permitted to sell them in the United States. To obtain approval, we must
show in preclinical and clinical trials that our products are safe and
effective. Clinical trial data can be the subject of differing interpretation,
and the FDA has substantial discretion in the approval process. The FDA may not
interpret our clinical data the way we do. The FDA may also require additional
clinical data to support approval.

    After we complete the clinical trials for a product, we will be required to
file a new drug application if the product is classified as a new drug, or a
biologics license application if the product is classified as a biologic, which
is a drug based on natural substances. The requirements for submission of these
applications and the FDA approval processes require substantial time and effort,
and the FDA may not grant approval on a timely basis or at all. The FDA can take
between one and two years to review new drug applications and biologics license
applications, or longer if significant questions arise during the review
process. In addition, delays or rejections may be encountered during FDA review.
Even after such time and expenditures, we may not obtain regulatory approval.
Any regulatory approval of a product that is granted may limit the indicated
uses for which the product may be marketed.

        If the FDA modifies existing guidelines for product development, the
time and costs associated with the development of products in our product line
may increase, in which case we may not be able to successfully develop our
products at the rate we anticipate or we may not be able to develop them at all.

    To market our products in countries outside of the United States, we and our
partners are required to obtain similar approvals from foreign regulatory
bodies. The foreign regulatory approval process includes all of the risks
associated with obtaining FDA approval, and approval by the FDA does not ensure
approval by the regulatory authorities of any other country. The process of
obtaining these approvals is time consuming and requires the expenditure of
substantial resources.


                                      -20-
<PAGE>   21

We face intense competition, which may limit our commercial opportunities and
our ability to become profitable.

    The pharmaceutical and biotechnology industries are highly competitive.
Products and therapies currently on the market or under development could
compete directly with some of our products. Numerous pharmaceutical and
biotechnology companies and academic research groups throughout the world are
engaged in research and development efforts with respect to therapeutic products
targeted at diseases or conditions addressed by us. Our commercial opportunities
will be reduced or eliminated if our competitors develop and market products
that are more effective, have fewer or less severe adverse side effects or are
less expensive than our products. In addition, many of our existing or potential
competitors, particularly large pharmaceutical companies, have substantially
greater financial, technical and human resources than we have. Many of these
competitors have more collective experience than we do in undertaking
preclinical testing and human clinical trials of new pharmaceutical products and
obtaining regulatory approvals for therapeutic product. Accordingly, our
competitors may succeed in developing and marketing products either that are
more effective than those that we may develop, alone or with our collaborators,
or that are marketed before any products we develop are marketed.

    If third party payors will not provide coverage or reimburse patients for
the use of our products, our revenues and profitability will suffer.

    Our products' commercial success is substantially dependent on whether
third-party reimbursement is available for the use of our products by hospitals,
clinics and doctors. Medicare, Medicaid, health maintenance organizations and
other third-party payers may not authorize or otherwise budget for the
reimbursement of our products. In addition, they may not view our products as
cost-effective and reimbursement may not be available to consumers or may not be
sufficient to allow our products to be marketed on a competitive basis.
Likewise, legislative proposals to reform health care or reduce government
programs could result in lower prices for or rejection of our products. Changes
in reimbursement policies or health care cost containment initiatives that limit
or restrict reimbursement for our products may cause our revenues to decline.

If product liability lawsuits are brought against us, we may incur substantial
costs.

    The testing and marketing of pharmaceutical products entails an inherent
risk of product liability. Our insurance may not provide adequate coverage
against potential product liability claims or losses, and insurance coverage may
not continue to be available to us on reasonable terms or at all. Even if we are
ultimately successful in product liability litigation, the litigation would
consume substantial amounts of our financial and managerial resources, and might
create adverse publicity, all of which would impair our ability to generate
sales.

RISKS RELATED TO OUR STOCK

Our stock price is volatile and the value of your investment in our stock could
decline in value.

    The market prices for securities of biotechnology companies like our company
have been and are likely to continue to be highly volatile. As a result,
investors in these companies often buy at very high prices only to see the price
drop substantially a short time later, resulting in an extreme


                                      -21-
<PAGE>   22

drop in value in the stock holdings of these investors. In addition, the
volatility could result in securities class action litigation. Any litigation
would likely result in substantial costs, and divert our management's attention
and resources.

If our officers, directors and principal stockholders act together, they may be
able to control our management and operations and they may make decisions that
are not in the best interests of other stockholders.

    Our directors, executive officers and principal stockholders and their
affiliates currently beneficially own in the aggregate approximately 65% of our
outstanding common stock. Accordingly, they collectively have the ability to
determine the election of all of our directors and to determine the outcome of
most corporate actions requiring stockholder approval. They may exercise this
ability in a manner that advances their best interests and not necessarily those
of other stockholders. This concentration of ownership may also have the effect
of delaying, deferring or preventing a change in control of our company, even if
the change in control would be beneficial to other stockholders.

Our charter documents and Delaware law contain provisions that could delay or
prevent an acquisition of us, even if the acquisition would be beneficial to our
stockholders.

    Our certificate of incorporation authorizes our board of directors to issue
undesignated preferred stock and to determine the rights, preferences,
privileges and restrictions of the preferred stock without further vote or
action by our stockholders. The issuance of preferred stock could make it more
difficult for third parties to acquire a majority of our outstanding voting
stock. We also have a stockholder rights plan, which entitles existing
stockholders to rights, including the right to purchase shares of preferred
stock, in the event of an acquisition of 15% or more of our outstanding common
stock, or an unsolicited tender offer for such shares. The existence of the
rights plan could delay, prevent, or make more difficult a merger or tender
offer or proxy contest involving us. Other provisions of Delaware law and of our
charter documents, including a provision eliminating the ability of stockholders
to take actions by written consent, could also delay or make difficult a merger,
tender offer or proxy contest involving us. Further, our stock option and
purchase plans generally provide for the assumption of such plans or
substitution of an equivalent option of a successor corporation or,
alternatively, at the discretion of the board of directors, exercise of some or
all of the option stock, including non-vested shares, or acceleration of vesting
of shares issued pursuant to stock grants, upon a change of control or similar
event.


ITEM 3.        QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

        We have supply contracts with Boehringer Ingelheim for Relaxin and CCL
Pharmaceuticals for Luxiq and OLUX. We also have a collaboration agreement with
Suntory for the development and commercialization of relaxin for the treatment
of scleroderma in Japan. As payments under these contracts are payable in local
currency, our financial results could be affected by changes in foreign currency
exchange rates. We have a bank loan that is sensitive to movement in interest
rates. Interest income from our investments is sensitive to changes in the
general level of U.S. interest rates, particularly since the majority of our
investments are in short-term instruments. Due to the nature of our short-term
investments, we have concluded that we face no material market risk exposure.
Therefore, no quantitative tabular disclosures are required.

Third Party which undertakes to perform those obligations of this Agreement

including specifically the obligation under SECTION 7.2.1.

        2.2 LICENSE TO FAULDING IMPROVEMENTS. Subject to the terms and

shall have the right to use or license such Faulding Improvement for any purpose

            2.3.1 The Parties acknowledge that the licenses granted to Faulding
in this Agreement include sublicenses under Third Party Licenses. Connetics

entered into prior to the Effective Date and all amendments, restatements or
renewals thereof. Connetics shall promptly disclose to Faulding any knowledge

patents or patent applications by Third Parties other than the Relaxin Patents.

            2.3.2 Connetics shall abide by the terms and conditions of all Third
Party Licenses to maintain the Third Party Licenses to which Faulding has taken
a sublicense for Faulding as Connetics' sublicensee. Connetics agrees not to
terminate or assign, nor by act or omission permit the termination or assignment
of, any of the Third Party Licenses to which Faulding has taken a sublicense,
nor to amend or by act or omission permit the amendment of any such Third Party
Licenses to the extent such an amendment would adversely affect Faulding's
rights under this Agreement, without Faulding's prior written consent, which
consent may be granted or withheld in Faulding's sole discretion. Within [*****]
entering into any amendment of a Third Party License, Connetics shall notify
Faulding and provide Faulding with a copy of the amendment.

        2.4 RESERVATION OF RIGHTS. No right, title, or interest is granted,
whether expressly or by implication, to any technology or intellectual property
rights owned by either Party, except for the rights and licenses expressly
granted under this Agreement, and each Party hereby reserves all rights not
expressly granted under this Agreement, nor shall anything in this Agreement be
deemed to restrict either Party from exploiting any of its rights not expressly
granted to the other Party under this Agreement.

        2.5 ENFORCEMENT OF LICENSED IP.

            2.5.1. A Party shall promptly notify the other Party if it becomes
aware of any infringement or misappropriation of the Licensed IP. As between the
Parties, Connetics shall have the primary right and discretion regarding
enforcement of the Licensed IP against Third Parties who may be infringing or
misappropriating such intellectual property rights. Connetics shall use
Commercially Reasonable Efforts, at its sole expense, to protect the exclusive
license granted to Faulding pursuant to this Agreement, taking into account the
costs and benefits of such action, including, without limitation, the costs to
be incurred in any such action and the amount and likelihood of the damages that
may be awarded in any such action.

            2.5.2. If Connetics (a) decides not to enforce the Licensed IP, or
having commenced an action fails to pursue it, or (b) does not bring such action
within sixty (60) days after receipt of Faulding's request to enforce the
Licensed IP, then Faulding may do so at its own



[*****] CONFIDENTIAL TREATMENT REQUESTED
<PAGE>   8

expense, and Connetics shall sign all documents and do all things necessary to
facilitate Faulding's exercising its rights under this subsection.

            2.5.3. In either case, the Party enforcing the Licensed IP at the
relevant time (the "ENFORCING PARTY") shall be entitled to recover all of its
actual costs, expenses and fees incurred in such action from the damages
awarded, and any remaining amount (subject to any amounts payable to any Third
Party licensee as a result of the damages awarded) shall be payable [*****] to
the Enforcing Party and [*****] to the Party not enforcing the Licensed IP (the
"NON-ENFORCING PARTY"). The Enforcing Party shall, in its sole discretion, have
the right to file and control such action as it deems warranted; provided,
however, that the Enforcing Party shall provide to the Non-enforcing Party and
its attorneys the following: (i) reasonable notice of, and permission to attend,
all meetings and proceedings related to such actions; (ii) copies of all
documents (including without limitation correspondence, notices, filings,
responses, requests, orders and rulings) related to such action in sufficient
detail and with sufficient time to enable the Non-enforcing Party to review and
provide comments on such documents; and (iii) timely information and updates
regarding the status of such action.

            2.5.4. The Non-enforcing Party agrees to cooperate with the
Enforcing Party to the extent reasonably requested by and at the expense of the
Enforcing Party, including, without limitation, being named as a party in such
proceeding. The Non-enforcing Party may choose to be represented by counsel of
its choice and at its own expense at all meetings, and to participate in all
discussions, but counsel for the Non-enforcing Party shall not be entitled to
appear in any legal or judicial proceedings.

        2.6 OTHER COUNTRIES. Connetics retains the right to grant licenses for
the sale, marketing and distribution of the Product in all countries outside the
Territory; provided, however, that Connetics agrees that for each such license
entered into after the Effective Date, it will impose on each such licensee, to
the extent permitted by applicable law, a covenant prohibiting the licensee
from: (a) seeking approval, directly or indirectly, from the relevant Regulatory
Authorities, to qualify facilities for manufacturing or finishing the Product
inside the Territory or to label or re-label the Product in a manner that would
permit it to be marketed or sold inside the Territory, (b) selling or exporting
the Product to any Third Party for use or resale inside the Territory, (c) or
selling the Product to any Third Party that Connetics has reason to believe
intends to resell or export the Product inside the Territory.


                                   ARTICLE III
                  CLINICAL DEVELOPMENT AND REGULATORY APPROVAL

        3.1 CLINICAL DEVELOPMENT.

            3.1.1 DEVELOPMENT COMMITTEE. The obligations and relationship
between the Parties pursuant to this Agreement shall be governed by a
development committee (the "DEVELOPMENT COMMITTEE"). Initially, and until such
time (if any) as Medeva objects, this provision shall be satisfied by the
inclusion of a Faulding representative on the Development Committee established
pursuant to the Medeva Agreement. If at any time Medeva asks that Faulding cease
to be represented on that Committee, then Connetics and Faulding shall, within
thirty (30) days after receipt of notice from Medeva, establish a separate
development committee



[*****] CONFIDENTIAL TREATMENT REQUESTED
<PAGE>   9

which will have the obligation to monitor progress and manage information
exchange between Connetics and Faulding. At the first meeting of the Development
Committee, the Parties shall establish a regular meeting time and structure.

                        MANUFACTURE AND COMMERCIALIZATION

        5.1 MANUFACTURE.

            5.1.1 CLINICAL SUPPLIES. Connetics shall, and shall cause its
Contract Manufacturer(s) to, commencing from the Effective Date until Faulding
receives Regulatory Approval to market the Product in the Territory, use
Commercially Reasonable Efforts to manufacture for and supply to Faulding, and
Faulding shall (subject to the terms of this Agreement) purchase, all Faulding's
required quantities of Relaxin Materials for use in Clinical Development;
including quantities required for any special access schemes or compassionate
use programs in the Territory, provided that Faulding shall not transfer the
Relaxin Materials or Product to any Third Party at any time except to the extent

Approval or compassionate use programs or special access schemes related to the
Product in the Field and Territory. The price for Product and/or Relaxin
Materials pursuant to this Section shall equal [*****].

            5.1.2 PRODUCT FOR COMMERCIAL SALE. Commencing upon Faulding's
initial purchase order and continuing until the termination or expiration of
this Agreement, Connetics shall, and shall cause its Contract Manufacturer(s),
to use Commercially Reasonable Efforts to manufacture for and supply to Faulding
all of Faulding's requirements for Product (based on Faulding's Annual Sales
Forecast) on the terms set forth in a Supply Agreement to be entered into as

[*****] CONFIDENTIAL TREATMENT REQUESTED

<PAGE>   12

similar types of products, and such additional terms and conditions as the
Parties may agree upon. If the Price to Faulding to purchase commercial supply
of Product exceeds forty percent (40%) of the Net Selling Price, then the
Parties shall recalculate the Price to Faulding and agree on a new price (the
"ADJUSTED PRICE TO FAULDING"). The Adjusted Price to Faulding shall equal the
original Price to Faulding minus the lesser of (1) fifty percent of the
difference between the original Price to Faulding and [*****] of the [*****],
and (2) [*****] of the [*****].

                Example 1. Solely for purposes of this Agreement, and by way of
                illustration, if the [*****] is [*****] and the Price to

                equal [*****]. The calculated reduction in the Price to Faulding
                is determined by the formula [*****]

                Example 2. Solely for purposes of this Agreement, and by way of
                illustration, if the [*****] is [*****] and the Price to
                Faulding is [*****], then the Adjusted Price to Faulding shall
                equal [*****]. The reduction in the Price to Faulding is limited
                to [*****], or [*****], which is less than the product of the
                calculation [*****]

Subject to SECTION 5.1.5 below, during the Term, Faulding shall purchase all its
requirements for Product from Connetics. Upon Faulding's request, during the

            5.1.4 INABILITY TO SUPPLY. If Connetics fails for any reason,
including without limitation a force majeure event described in SECTION 11.7, to
deliver Relaxin Materials and/or Product to Faulding, and such inability to
supply continues for more than [*****] without a plan (acceptable to Faulding)
by which Connetics proposes to cure the inability to supply within [*****] after
the inability first impacted Faulding, then Connetics hereby agrees to allocate
to Faulding a percentage of available Product equivalent to the percentage of
sales of Product in the Territory compared to sales of Product throughout the
world in the preceding [*****]. Alternatively, Faulding shall have the right
under such circumstances to contract with another supplier.

of the Term of this Agreement.

            5.1.6 RISK OF LOSS. All shipments shall be [*****], as defined by
the [*****], and Faulding shall bear the risk of loss and cost of transportation
of the Relaxin Materials and/or Product upon delivery by Connetics to [*****].

<PAGE>   14

            5.2.4 ANNUAL ADJUSTMENTS TO ROYALTY PAYMENTS BASED ON ACTUAL NET
SALES. At the end of each Year, if Net Sales are above the Forecast, Faulding
shall pay Connetics an amount equal to the difference between the Royalty
calculated and paid according to the Forecast for that Year, as it may have been
adjusted from time to time through the Year, and the Royalty owing on the actual
Net Sales for that Year. At the end of each Year, if Net Sales are below the
Forecast, Connetics shall refund to Faulding an amount equal to the difference
between the Royalty calculated and paid according to the Forecast for that Year,
as it may have been adjusted from time to time through the Year, and the Royalty
owing on the actual Net Sales for that Year. At the end of each Year the actual
royalty payable for the year will be calculated in accordance with SECTION 5.2.1
above. Faulding will make a final royalty payment (or if necessary request a
credit) so that the total royalty paid for the Year equals the amount payable in
accordance with SECTION 5.2.1.

            5.2.5 INITIAL PERIOD OF SALES. During the period of time between the
Launch Date in the Territory and the beginning of the next Year, Faulding shall
pay Connetics Royalties in accordance with SECTIONS 5.2.1. TO 5.2.4 above,
except that, for the determination of the average percentage royalty rate for
quarterly royalty payments, Faulding's forecast shall be annualized (scaled up
to an annual equivalent amount), and to determine the actual royalty rate
payable for the total period, Faulding's actual sales shall be annualized.

            5.2.6 ANNUAL SALES FORECAST. Faulding shall provide Connetics with a
projected total annual Net Sales of Relaxin in the Territory for each Year, no
later than ninety (90) days before the beginning of the Year.

within thirty (30) days after receipt of the invoice.

            5.3.3 NONCONFORMING CLINICAL SUPPLIES.

                (a) Within [*****] after the delivery of Relaxin Materials and
        the accompanying Certificate of Analysis to Faulding, Faulding shall
        submit to Connetics in writing any claim that Relaxin Materials do not
        conform with the Specifications, accompanied by a report of Faulding's
        analysis (which analysis shall be conducted in good faith) and a sample
        of the Relaxin Materials at issue, explaining in reasonable detail the
        basis on which the allegedly nonconforming Relaxin Materials does not
        meet the Specifications. Faulding shall not be obligated to pay for such
        nonconforming shipment of Relaxin Materials. Only those tests listed in
        the Specifications may be used to demonstrate nonconformance of Relaxin
        Materials.

                (b) Connetics shall conduct its own analysis of the sample in
        good faith within [*****] after the receipt by Connetics of the report

[*****] CONFIDENTIAL TREATMENT REQUESTED
<PAGE>   15

        and provide the results to Faulding. If, after analysis, Connetics
        agrees with the claim of nonconformity, Connetics shall replace the
        nonconforming Relaxin Materials with conforming Relaxin Materials at
        Faulding's request, in which case Faulding shall be obligated to pay
        only for such replacement Relaxin Materials. Faulding shall not be
        obligated to pay for the nonconforming Relaxin Materials, and Connetics
        shall credit Faulding for any amounts already paid for the nonconforming
        Relaxin Materials, and/or cancel its invoice to Faulding for such
        nonconforming Relaxin Materials if Faulding has not yet paid. If, after
        its own analysis, Connetics disagrees with the claim of nonconformity or
        determines that Faulding is responsible for the nonconformity, the
        Parties shall in good faith discuss and agree upon a settlement of the
        issue, and Faulding shall not be obligated to pay for such alleged
        nonconforming Relaxin Materials until such settlement is reached.

                (c) After Connetics has agreed that the Relaxin Materials
        shipment is nonconforming, and if the nonconformity is not the fault of
        Faulding, then Faulding shall return or destroy it at Connetics' request
        and cost in the most cost effective and environmentally safe and
        appropriate manner available, consistent with federal, state and local
        laws and regulations.

                (d) If conforming Relaxin Materials supplied under this
        Agreement become nonconforming or unsuitable at no fault of Connetics,
        Faulding will remain obligated to pay Connetics for such Relaxin
        Materials. At Connetics' request, Faulding shall return such unsuitable
        Relaxin Materials to Connetics. Otherwise, Faulding shall destroy it in
        the most environmentally safe and appropriate manner available,
        consistent with federal, state and local laws and regulations.

give the indemnifying party (the "INDEMNITOR") prompt written notice of any
Losses or discovery of fact upon which such indemnified party intends to base a
request for indemnification under SECTION 6.4 or 6.5. Notwithstanding the
foregoing, the failure to give timely notice to the Indemnitor shall not release
the Indemnitor from any liability to the Indemnitee to the extent the Indemnitor
is not prejudiced thereby.

            6.6.2 COPIES. The Indemnitee shall furnish promptly to the
Indemnitor copies of all papers and official documents in the Indemnitee's
possession or control which relate to any Losses; provided, however, that if the

Indemnitor shall also provide such papers and documents to the Indemnitee. The
Indemnitee shall cooperate with the Indemnitor in providing witnesses and
records necessary in the defense against any Losses.



[*****] CONFIDENTIAL TREATMENT REQUESTED

<PAGE>   20

            6.6.3 PARTICIPATION. The Indemnitor shall have the right, by prompt
notice to the Indemnitee, to participate in the defense of any third party claim
forming the basis of such Losses with counsel reasonably satisfactory to the
Indemnitee, and at the sole cost of the Indemnitor so long as (a) the Indemnitor
promptly notifies the Indemnitee in writing (but in no event more than 60 days
after its receipt of notice of the claim) that it will indemnify the Indemnitee
from and against any Losses the Indemnitee may suffer arising out of the claim,
and (b) the Indemnitor diligently participates the defense of the claim.

            6.6.4 CONTROL OF DEFENSE. If the Indemnitor participates in the
defense of the claim as provided above, the Indemnitee may at its option
relinquish total control to the Indemnitor or participate in such joint defense
with its own counsel who shall be retained, at the Indemnitee's sole cost and
expense; provided, however, that neither the Indemnitee nor the Indemnitor shall
consent to the entry of any judgment or enter into any settlement with respect
to the claim without the prior written consent of the other party, which consent
shall not be reasonably withheld or delayed. If the Indemnitee withholds consent
in respect of a judgment or settlement involving only the payment of money and
which would not involve any stipulation or admission of liability or result in
the Indemnitee becoming subject to injunctive relief or other relief, the
Indemnitor shall have the right, upon notice to the Indemnitee within five (5)
days or receipt of the Indemnitee's written denial of consent, to pay to the
Indemnitee the full amount of such proposed judgment or settlement, including
all interest, costs or other charges relating thereto, and shall pay all
attorneys' fees incurred to such date for which the Indemnitor is obligated
under this Agreement, if any at which time the Indemnitor's rights and
obligations and duty to indemnify with respect to the claim shall cease.

            6.6.5 SETTLEMENT. If the Indemnitor does not so participate in the
defense of such claim, the Indemnitee may conduct such defense with counsel of
its choice and at the sole cost of the Indemnitor and may settle such case (for
monetary damages only) as it shall determine in the exercise of its reasonable
discretion. Except as provided in this SECTION 6.6.5, the Indemnitor shall not
be liable for any settlement or other disposition of a Loss by the Indemnitee
which is reached without the written consent of the Indemnitor.

            6.6.6 COSTS AND EXPENSES. Except as provided in this SECTION 6.6,
the costs and expenses, including fees and disbursements of counsel, incurred by
any Indemnitee in connection with any claim shall be reimbursed on a calendar
quarter basis by the Indemnitor, without prejudice to the Indemnitor's right to
contest the Indemnitee's right to indemnification and subject to refund in the
event the Indemnitor is ultimately held not to be obliged to indemnify the
Indemnitee.

        6.7 LIMITATION OF LIABILITY. EXCEPT FOR ANY LOSS, LIABILITY, DAMAGE OR
OBLIGATION ARISING OUT OF OR RELATING TO THE INABILITY TO SUPPLY THE PRODUCT,
DISCLOSURE OF CONFIDENTIAL INFORMATION PURSUANT TO ARTICLE VIII, OR AS PROVIDED
IN SECTION 6.4 OR 6.5, IN NO EVENT SHALL EITHER PARTY HAVE ANY LIABILITY TO THE
OTHER PARTY OR ANY OTHER THIRD PARTY FOR ANY LOST OPPORTUNITY OR PROFITS, OR FOR
ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR SPECIAL DAMAGES ARISING OUT
OF A BREACH OF THIS AGREEMENT, UNDER ANY CAUSE OF ACTION OR THEORY OF LIABILITY
(INCLUDING NEGLIGENCE), AND WHETHER OR NOT SUCH PARTY TO THIS AGREEMENT HAS BEEN
ADVISED OF THE POSSIBILITY OF SUCH DAMAGE. THESE LIMITATIONS SHALL APPLY
NOTWITHSTANDING ANY FAILURE OF ESSENTIAL PURPOSE OF ANY LIMITED REMEDY.

published standards of the FDA.

            7.1.3 PERMITS; LICENSES. Connetics will maintain in effect all
governmental permits, licenses, orders, applications and Regulatory Approvals,

Product in accordance with such governmental permits, licenses, orders,

                                  ARTICLE VIII
                          CONFIDENTIALITY AND PUBLICITY

        8.1 PUBLIC RELATIONS AND ANNOUNCEMENTS. The Parties shall provide
courtesy copies of any public announcements concerning the relationship created
by this Agreement. Neither Party shall make any representations concerning the
other without the prior consent from the other Party. Except for such disclosure
as is required by applicable law and/or stock exchange regulation, neither Party
shall make any announcement, news release, public statement, publication or
presentation relating to the existence of this Agreement or the arrangements
referred to in this Agreement without the other Party's prior consent, which
consent will not be unreasonably withheld or delayed.

        8.2 CONFIDENTIALITY.

            8.2.1 CONFIDENTIAL INFORMATION. The Parties acknowledge that by
reason of their relationship to each other under this Agreement, each will have
access to certain information and materials concerning Relaxin Information, the
other's business, plans, trade secrets, customers (including, but not limited
to, customer lists of both Parties), technology, and/or products that is
confidential and of substantial value to that Party, which value would be
impaired if such information were disclosed to Third Parties ("CONFIDENTIAL
INFORMATION"). Each Party agrees that it will not use in any way other than
expressly authorized or contemplated under this Agreement, nor disclose to any
Third Party, any such Confidential Information revealed to it by the other Party
(except that Confidential Information may be disclosed, as required for the
purposes of this Agreement, to any Regulatory Authority, an Affiliate, assignee,
distributor, consultant or Third Party contractor or research and development
organization under similar written obligations of non-disclosure and non-use),
and will take every reasonable precaution to protect the confidentiality of such
information and with no less restrictive precautions than it takes to protect
its own confidential information. If Confidential Information is required to be
disclosed in response to a valid order by a court, regulatory authority or other
government body of competent jurisdiction, or if otherwise required to be
disclosed by law, or if necessary to establish the rights of either Party under
this Agreement, the receiving Party shall use commercially reasonable efforts to
provide the disclosing Party with advance notice of such required disclosure to
give the disclosing Party sufficient time to seek a protective order or other
protective measures, if any are available, for such Confidential Information.

            8.2.2 EXCEPTIONS. For purposes of this Agreement, information shall
be deemed Confidential Information if such information, by its nature or due to
the context within which it is disclosed, is obviously intended by the
disclosing Party to be kept confidential even if not identified as such in
writing or with legends or other markings, provided that Relaxin Information
shall automatically be treated as Confidential Information. Upon request by
either Party, the other Party will advise whether or not it considers any
particular information or materials to be Confidential Information. Confidential
Information does not include information, technical data or know-how which: (a)
is rightfully in the possession of the receiving Party at the time of disclosure
as shown by the receiving Party's files and records immediately prior to the
time of disclosure; (b) becomes part of the public knowledge or literature, not
as a result of any inaction or action of the receiving Party; (c) is
independently developed by a Party without the use of any Confidential
Information of the other Party; (d) is obtained from any Third Party who is
authorized to disclose such data and information without obligation of
confidentiality to the disclosing party, or (e) is approved for release in
writing by the disclosing Party.

        8.3 REMEDY. If either Party breaches any of its obligations with respect

injunction, in addition to any other rights or remedies, including money
damages, provided by law, without posting a bond.

        8.4 AGREEMENT TERMS. Subject to SECTION 8.1 and the exclusions set forth
in SECTION 8.2.2, the Parties shall treat the terms and conditions of this
Agreement as Confidential Information; provided, however, after written
notification to the other Party, each Party may disclose the existence of this
Agreement and the material terms and conditions of this Agreement under
circumstances that reasonably ensure the confidentiality thereof to: (a) any
government or regulatory authorities, including without limitation the United
States Security and Exchange Commission pursuant to applicable law (excluding,
to the extent legally permitted, disclosure of financial terms in any publicly
available versions of information so disclosed), (b) its legal representatives,
advisors and prospective investors, and (c) to Connetics' licensors to the
extent required for compliance with Connetics' obligations under the Third Party
Licenses.

practicable after notice of the Connetics Breach.

            9.2.2 FOR BREACH BY FAULDING. Upon breach by Faulding of any of its
material obligations contained in this Agreement ("FAULDING BREACH"), Connetics

             10.1.1 Connetics shall advise Faulding by telephone and facsimile
immediately of any proposed or announced visit or inspection, and as soon as

documentation, and opportunity to comment provided for above with respect to
Contract Manufacturers.

             10.1.2 Each Party shall notify, and shall cause its Affiliates and
sublicensees to notify, the other Party promptly upon receipt of:



[*****] CONFIDENTIAL TREATMENT REQUESTED

<PAGE>   27

        (a)     any information regarding any pending or threatened action which
                may affect the safety or efficacy claims of the Product or the
                continued marketing of the Product in any nation or
                jurisdiction,

        (b)     any material communications with or notice from a Regulatory
                Authority indicating that it intends to visit or inspect a
                Party's facilities, or the facilities of an Affiliate or
                sublicensee of such Party, for a purpose relevant to the
                development, manufacture or marketing of the Product.

        (c)     a communication or directive from a Regulatory Authority
                commencing or threatening seizure of (or other removal from the
                market of) Relaxin, Relaxin Materials, or Product.

        10.2 ADVERSE EXPERIENCE REPORTING. Each Party shall comply with the
provisions of EXHIBIT D as though it were fully set forth in this Agreement,
with respect to notification and reporting of adverse drug experiences and/or
adverse events. Without limiting the foregoing, each Party shall make such
reports as are necessary to comply with laws and regulations applicable to it,
at its sole expense.

        10.3 NOTIFICATION AND RECALL. If any Regulatory Authority issues or
requests a recall or takes similar action in connection with Relaxin or the
Product, or if either Party determines that an event, incident or circumstance
has occurred which may result in the need for a recall or market withdrawal, the
Party notified of or wishing to call such recall or similar action shall, within
twenty-four (24) hours, advise the other Party of notification or its
determination by telephone or facsimile, after which the Parties shall promptly
discuss and work together to effect an appropriate course of action; provided,
however, that either Party may initiate a recall or market withdrawal thereafter
if it deems such action necessary or appropriate. Connetics shall be responsible
for notification to FDA (or such other applicable Regulatory Authority with
respect to countries other than the United States and the Territory) and
compliance with applicable laws outside the Territory in conducting such recall.
Faulding shall be responsible for notification to the applicable Regulatory
Authority with respect to countries in the Territory and compliance with
applicable laws in the Territory in conducting such recall.

        10.4 RECALL EXPENSE. If a recall results from the breach of a Party's
warranties or obligations under this Agreement, the breaching Party shall bear
the full expense of both Parties incurred in any such recall. Such expenses of
recall shall include, without limitation, the expenses of notification and
destruction or return of the recalled Product and the sum paid for the recalled
Product. Without limitation of the foregoing, if the failure to meet applicable
legal requirements is caused by the act or omission of Connetics in manufacture
or sale of Product to Faulding, (a) Connetics shall have the option of (i)
replacing the recalled Product, or (ii) reimbursing Faulding for any amounts
paid to Connetics by Faulding under this Agreement for Product which are
recalled and/or cannot be shipped by Faulding due to the condition requiring the
recall, and (b) with respect to Product manufactured by Connetics, Connetics
shall reimburse Faulding for all liabilities incurred by Faulding by virtue of
being unable to meet its supply obligations to its customers because Product
could not be shipped by Connetics or Faulding due to the condition requiring
recall. In the event, however, that a recall is partially caused by Connetics'
actions or omissions and partially



[*****] CONFIDENTIAL TREATMENT REQUESTED
<PAGE>   28

caused by Faulding's actions or omissions, then each Party shall be responsible
for its proportionate share of the recall expenses based on its proportionate
share of causation.


                                   ARTICLE XI
                                  MISCELLANEOUS

        11.1 TAXES, TARIFFS, FEES. Faulding shall have the right to deduct from
the payments set forth in SECTION 4.1 any withholding tax applicable to
Connetics' income which Faulding is obliged to pay by under applicable law;
provided however that Faulding shall provide Connetics with an appropriate tax
receipt for the deducted amount which Connetics can present to its tax authority
and sufficient for Connetics to receive the corresponding credit to which it is
entitled. The Parties agree to cooperate in all respects necessary to take
advantage of such double taxation agreements as may be available to optimize the
tax obligations of each Party.

        11.2 CURRENCY OF PAYMENTS. For purposes of calculating Net Sales and
payments to be made to Connetics in respect of Net Sales, all amounts payable to
Connetics by Faulding pursuant to this Agreement shall be made to Connetics in
U.S. dollars and by wire transfer to the U.S. bank account(s) specified by
Connetics from time to time. Faulding shall apply a conversion rate from
Australian currency to U.S. dollars for amounts payable under this Agreement
equal to the average of the conversion rates in effect on the last day of each
month in the quarterly period for which such payment is due. The conversion
rates to be used in this Agreement shall be the rates reported in the Wall
Street Journal (West Coast Edition).

        11.3 COMPLIANCE WITH LAWS. In performing this Agreement, each Party
shall comply with all applicable laws and government regulations at all times,
including but not limited to any applicable laws and regulations in the
Territory and the U.S. with respect to the export or re-export or release of
technology and technical data.

        11.4 DISPUTE RESOLUTION AND GOVERNING LAW. The Parties shall endeavor to
resolve in good faith any disputes, controversy, conflicts or claims arising
from or relating to the subject matter of this Agreement, or the breach or
termination of this Agreement, failing which the following process shall apply:

             11.4.1 MEDIATION. The dispute, controversy or claim shall first be
referred to the chief executive officer of each of Faulding and Connetics for
resolution at a place to be agreed between such chief executive officers and,
failing agreement, at the head office of the Faulding (if Connetics requests the
referral) or Connetics (if Faulding requests the referral).

             11.4.2 FORMAL ARBITRATION. If the dispute, controversy or claim is
not settled or agreed between such chief executive officers within a period of
one (1) month, then it shall be settled by arbitration in accordance with the
[*****] then in effect. At the written request of either party, Faulding and
Connetics may each nominate one or more appropriately qualified experts, but
both parties must agree to the expert to be appointed. If the Parties are unable
to agree on an expert or experts, the arbitration will be conducted by a panel
of three (3) arbitrators who are knowledgeable in the subject matter that is at
issue in the dispute, are not affiliated directly or indirectly with either
Party, one of whom is selected by Faulding, one of whom is selected by
Connetics, and one of whom is selected by the mutual agreement of the other two
arbitrators.




[*****] CONFIDENTIAL TREATMENT REQUESTED
<PAGE>   29

During the arbitration, the Parties shall have such discovery rights as the
arbitrators may allow, consistent with the discovery permitted by the Federal
Code of Civil Procedure.

            11.4.3 POWERS OF ARBITRATORS. In any arbitration pursuant to this
section, the arbitrators shall be able to decree any and all relief of an
equitable nature, including but not limited to such relief as a temporary
restraining order, a preliminary or permanent injunction, as well as specific
performance. The arbitrators shall also be able to award direct and indirect
damages, but shall not award any other form of damage (e.g., punitive or
exemplary damages). The reasonable fees and expenses of the arbitrators, the
fees and expenses of a court reporter, and any expenses for a hearing room,
shall be borne equally by the Parties. The decision of the arbitrators shall be
final and will be handed down within a period of sixty days of being appointed.
The Party in whose favor the decision runs may enter, sue on or enforce the
decision in any court of competent jurisdiction at the option of such Party.

            11.4.4 GOVERNING LAW. This Agreement shall be governed, controlled,
interpreted and defined by and under the laws of the [*****] without regard to
that body of law known as conflicts of law. The place of arbitration shall be
[*****]. The arbitrators shall apply the law of the [*****] (regardless of that
jurisdiction's or any other jurisdiction's choice of law principles). The
Parties specifically disclaim application to this Agreement of the Convention on
Contracts for the International Sale of Goods.

        11.5 SECTION HEADINGS. The section headings contained in this Agreement
are included for convenience of reference only and form no part of the agreement
between the Parties. Therefore, the headings shall not affect in any way the
meaning or interpretation of this Agreement.

        11.6 NOTICES. Any notice required or permitted by this Agreement shall
be in writing and shall be sent by prepaid registered or certified mail, return
receipt requested; by facsimile; by internationally recognized courier; or by
personal delivery, in each case addressed to the other Party as follows:

If to Faulding, to:

               F. H. Faulding & Co. Limited
               Attn:  The Company Secretary

               AUSTRALIA
               Facsimile +61 8 8234 8230


Either Party may designate a different address by giving notice pursuant to this
Section to the other Party. Any notice given pursuant to this Section shall be
deemed to have been given when delivered or, if delivery is not accomplished by
some fault of the addressee, when tendered.

        11.7 FORCE MAJEURE. Neither Party shall be considered in default of
performance of its obligations under this Agreement, except any obligation under
this Agreement to make payments when due, to the extent that performance of such
obligations is delayed by contingencies or causes beyond the reasonable control
and not caused by the negligence or willful misconduct of such Party, including
but not limited to strike, fire, flood, earthquake, windstorm, governmental acts
or orders or restrictions, or force majeure, to the extent that the failure to
perform is beyond the reasonable control of the nonperforming Party.

        11.8 NONASSIGNABILITY AND BINDING EFFECT. Each Party agrees that its
rights and obligations under this Agreement may not be transferred or assigned
directly or indirectly, except as follows: (a) either Party may transfer or
assign this Agreement to an Affiliate of such Party which agrees in writing to
undertake the obligations under this Agreement provided the assigning Party
remains primarily liable, (b) either Party may transfer or assign this Agreement
in connection with the sale of all or substantially all of the assigning Party's
related business, and (c) either Party may transfer or assign this Agreement to
a non-Affiliate Third Party with the prior written consent of the other Party,
which consent shall not be unreasonably withheld. Subject to the foregoing, this
Agreement shall be binding upon and inure to, the benefit of the Parties, their
successors and assigns. Any attempted assignment contrary to the provisions of
this SECTION 11.8 shall be deemed ineffective, and either Party shall have the
right to terminate this Agreement, with the effect described in SECTION 9.3.1
with respect to a Connetics Breach or a Faulding Breach, as applicable.

        11.9 PARTIAL INVALIDITY. If any provision of this Agreement is or
becomes or is deemed to be invalid, illegal, or unenforceable in any
jurisdiction: (a) such provision will be deemed amended to conform to applicable
laws of such jurisdiction so as to be valid and enforceable, or, if it cannot be
so amended without materially altering the intention of the parties, it will be
stricken; (b) the validity, legality and enforceability of such provision will
not in any way be affected or impaired thereby in any other jurisdiction; and
(c) the remaining provisions of this Agreement will remain in full force and
effect. The Parties agree to renegotiate in good faith any term held invalid and
to be bound by the mutually agreed substitute provision in order to give the
most approximate effect intended by the Parties.

        11.10 NO WAIVER. No failure or delay on the part of a party in
exercising any right under this Agreement will operate as a waiver of, or
impair, any such right, unless a waiver is made in writing signed by the waiving
party. No single or partial exercise of any such right will preclude any



[*****] CONFIDENTIAL TREATMENT REQUESTED
<PAGE>   31

other or further exercise thereof or the exercise of any other right. No waiver
of any such right will be deemed a waiver of any other right under this
Agreement.

        11.11 COUNTERPARTS. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original and all of which
together shall constitute one instrument.

        11.12 ENTIRE AGREEMENT. This Agreement, including the attached Exhibits
which are incorporated in this Agreement by reference, constitutes the entire
agreement of the Parties with respect to the subject matter, and supersedes all
prior or contemporaneous understandings or agreements, whether written or oral,
between Connetics and Faulding with respect to such subject matter.
Specifically, this Agreement supercedes in their entirety the Confidential
Disclosure Agreement between the Parties dated August 13, 1999, and the Letter
of Understanding signed by the Parties effective February 7, 2000, both of which
shall have no further force or effect as of the Effective Date. This Agreement
may not be modified except by a writing signed by the Parties' authorized
representatives, and no amendment or modification of this Agreement shall be
valid or binding upon the Parties unless made in writing and signed by the duly
authorized representatives of both Parties.

        11.13 INDEPENDENT CONTRACTORS. The Parties to this Agreement are
independent contractors. This Agreement does not establish a relationship of
agency, partnership, joint venture, employment or franchise between the Parties
and neither Party shall have any authority to bind the other Party or incur any
obligation on the other Party's behalf.


The undersigned have executed this Agreement on behalf of the Parties as of the
Effective Date.
