1.  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

ORGANIZATION

Arris Pharmaceutical Corporation, a Delaware corporation ("Arris" or the 
"Company"), uses an integrated drug discovery approach combining 
structure-based drug design, combinatorial chemistry and its proprietary 
Delta Technology to discover and develop a number of diverse synthetic small 
molecule therapeutics for commercially important disease categories where 
existing therapies have significant limitations.  Arris' product development 
programs include protease discovery programs targeting the inhibition of 
enzymes implicated in asthma, inflammatory disease, osteoporosis, cancer and 
autoimmune disease.  The Company's technology platform also includes 
receptor-based discovery programs designed to discover small molecule drugs 
that mimic important therapeutic proteins that are already successful 
products.

The consolidated financial statements include the accounts of the Company and 
its wholly-owned subsidiaries, Arris Protease, Inc., and Arris 
Pharmaceuticals Canada, Inc. ("Arris Canada").  All significant intercompany 
accounts and transactions have been eliminated.

BASIS OF PRESENTATION

The unaudited consolidated financial statements included herein have been 
prepared by the Company according to the rules and regulations of the 
Securities and Exchange Commission.  Certain information and footnote 
disclosures normally included in complete financial statements prepared in 
accordance with generally accepted accounting principles have been condensed 
or omitted pursuant to such rules and regulations.  The financial statements 
reflect, in the opinion of management, all adjustments (which include only 
normal recurring adjustments) necessary to state fairly the financial 
position and results of operations as of and for the periods indicated.  The 
results of operations for the three- and nine-month periods ended September 
30, 1997 are not necessarily indicative of the results to be expected for 
subsequent quarters or the full fiscal year. 

These financial statements should be read in conjunction with the audited 
financial statements and the notes thereto included in the Company's 1996 
Annual Report on Form 10-K filed with the Securities and Exchange Commission.

                NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
                                           

2.  NOTE PAYABLE

On September 29, 1997, the Company replaced its Bank of America line of 
credit with a new credit agreement with Sumitomo Bank, Limited and Silicon 
Valley Bank jointly to provide up to $20 million dollars in debt financing.  
Interest only payments are due quarterly until September 30, 1998, at which 
time principal and interest is payable in 48 monthly installments.  Interest 
is computed on a Eurodollar rate, which was approximately 7.7% on September 
30, 1997.  The loan is subject to certain financial covenants over the course 
of the agreement.  The Company was in compliance with all covenants at 
September 30, 1997.  The balance outstanding on this loan at September 30, 1997 
was $11.8 million.

3. STOCK OPTION PLANS

On May 21, 1997, stockholders approved the Company's 1989 stock option plan, 
as amended to increase the aggregate number of shares of common stock 
authorized for issuance under such plan by 750,000 shares, to 3,417,500 
shares.

On August 31, 1997, the Company adopted the 1997 Non-Officer Equity Incentive 
Stock Option Plan, whereby non-officer employees and consultants may be 
issued nonqualified stock options to purchase the Company's common stock at 
the discretion of the board of directors.  All options granted under this 
plan become exercisable pursuant to the applicable terms of the grant.  
Generally the exercise price of the options are granted at fair market value, 
vest ratably over four years and expire ten years from the date of grant.

4.  EARNINGS PER SHARE

In February 1997, the Financial Accounting Standards Board issued Statement 
No. 128, Earnings per Share, which is required to be adopted on December 31, 
1997. At that time, the Company will be required to change the method 
currently used to compute earnings per share and to restate all prior 
periods.  Under the new requirements for calculating basic earnings per 
share, the dilutive effect of stock options will be excluded.  The 
requirement is expected to have no effect on earnings per share for the nine 
months ended September 30, 1997 and 1996. The impact of Statement 128 on the 
calculation of diluted earnings per share for these periods is also expected 
to have no effect.

5.  OTHER RECENT PRONOUNCEMENTS

In 1997, Statement of Financial Accounting Standard No. 130 (SFAS 130) 
"Reporting Comprehensive Income" and Statement of Financial Accounting 
Standard No. 131 (SFAS 131), "Disclosures About Segments of an Enterprise and 
Related Information" were issued and are effective for fiscal years 
commencing after December 15, 1997.  The Company will comply with the 
requirements of SFAS 130 and SFAS 131 in fiscal year 1998.

6.  SUBSEQUENT EVENT

On November 2, 1997, the Company signed a definitive agreement with Sequana 
Therapeutics, Inc. ("Sequana"), pursuant to which the Company will acquire 
all of the outstanding Common Stock of Sequana based on an exchange ratio of 
1.35 shares of the Company's Common Stock for each share of Sequana. The 
acquisition will be accounted for as a "purchase" and is valued at  
approximately $166 million.

                           AND RESULTS OF OPERATIONS


THIS QUARTERLY REPORT ON FORM 10-Q CONTAINS, IN ADDITION TO HISTORICAL 
INFORMATION, FORWARD-LOOKING STATEMENTS THAT INVOLVE RISKS AND UNCERTAINTIES. 
THE COMPANY'S ACTUAL RESULTS COULD DIFFER SIGNIFICANTLY FROM THE RESULTS 
DISCUSSED IN THE FORWARD-LOOKING STATEMENTS.  FACTORS THAT COULD CAUSE OR 
CONTRIBUTE TO SUCH DIFFERENCES INCLUDE, BUT ARE NOT LIMITED TO, THOSE 
DISCUSSED UNDER "CERTAIN BUSINESS RISKS" BELOW AS WELL AS ELSEWHERE HEREIN, 
TOGETHER WITH THOSE DISCUSSED IN "ITEM 1. BUSINESS" AND "BUSINESS RISKS" IN 
THE COMPANY'S REPORT ON FORM 10-K FOR THE YEAR ENDED DECEMBER 31, 1996, FILED 
MARCH 31, 1997.

OVERVIEW

Since its inception in April 1989, the Company has devoted substantially all 
of its resources to its research and development programs.  To date, the 
Company's only source of revenue has been its corporate collaborations with 
Pharmacia & Upjohn, Inc. and its predecessors ("PNU"), Amgen, Inc. ("Amgen"), 
Bayer AG ("Bayer"), SmithKline Beecham Corporation ("SB"), Merck & Co. 
("Merck") and Abbott Laboratories ("Abbott").  Its collaborations have taken 
a variety of forms including, in each case, certain of the following 
elements:  payments to the Company of an up-front commitment fee, purchase of 
the Company's common stock (PNU human growth hormone collaboration only), 
research funding payments, purchase of compounds produced, milestone payments 
when milestones are achieved, and royalties upon the sale of any resulting 
products.  Where appropriate, the up-front commitment fees have been recorded 
as deferred revenue until earned.

In September 1997, the Company announced the results of the third in a series 
of Phase IIa studies of APC-366, a tryptase inhibitor for the treatment of 
asthma. The results of this crossover study of bronchial hyperresponsiveness 
showed improvement over the placebo control in two-thirds of the trial's 
asthmatic patients, however, did not reach statistical significance as 
measured by the amount of histamine (PD-20) required to produce a drop of 20 
percent or more in FEV-1, a measure of lung function.  

The Company has not been profitable since inception and expects to incur 
substantial losses for at least the next several years, primarily due to the 
cost of its research and development programs, including preclinical studies 
and human clinical trials.  The Company expects that losses will fluctuate 
from quarter to quarter, that such fluctuations may be substantial, and that 
results from prior quarters may not be indicative of future operating 
results. As of September 30, 1997, the Company's accumulated deficit was 
approximately $70.6 million.

RESULTS OF OPERATIONS

Revenue 

The Company's revenues increased to $5.5 million and $18.4 million for the 
three- and nine-month periods ended September 30, 1997, respectively, 
compared to $5.2 million and $16.2 million, respectively, for the comparable 
periods in 1996.  All of the Company's revenues presently are attributable to 
collaborations with PNU, Amgen, Bayer, SB, Merck and Abbott. The increases in 
1997 were primarily due to: (i) the full effects of the research funding for 
the

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

collaboration with SB to develop inhibitors using Arris' Delta technology 
targeting intracellular viral proteases, which commenced in June 1996 and 
expanded in July 1997;  (ii)  the research funding for  the collaboration 
with Merck to develop small molecule inhibitors of proteases involved in 
osteoporosis, which commenced in November 1996;  (iii)  the shipment of small 
molecule synthetic organic compounds under the combinatorial chemistry 
collaboration with PNU (250,000 total compounds are due under the three-year 
agreement), which commenced in March 1996; and  (iv)  the recognition of a 
portion of a license fee from Abbott for the transfer of technology, which 
commenced in June 1997.  These increases were partially offset by lower 
revenues recognized under the erythropoeitin collaboration with Amgen, in 
which the research funded portion ended during the first quarter of 1997 and 
the human growth hormone collaboration with PNU, in which the research funded 
portion will end in 1997.
                                           
Research and development

Research and development expenses increased to $7.5 million and $22.8 million 
for the three- and nine-month periods ended September 30, 1997, respectively, 
from $5.6 and $18.1 million in the comparable periods in 1996.  This increase 
was primarily due to the higher expenditures associated with the clinical 
trials of APC-366 and investments in proprietary research programs.  Research 
and development expenses as a percentage of total expenses has remained 
relatively constant at approximately 80% and 82% of total expenses for the 
three- and nine-months ended September 30, 1997 and approximately 79% and 82% 
for the comparable periods in 1996.  The Company expects its research and 
development costs will increase for the remainder of 1997 in absolute dollars 
when compared to 1996 as a result of further expansion of its proprietary 
research programs, conduct of preclinical studies, and clinical trials. 

General and administrative

The Company's general and administrative expenses increased to $1.9 million 
and $5.1 million for the three- and nine-month periods ended September 30, 
1997, from $1.3 and $3.9 million in the comparable periods in 1996.  The 
increase in expenses for the three- and nine-month periods was primarily due 
to additional headcount in Business Development and Finance, as well as costs 
associated with additional facility space.  In spite of the overall increase, 
general and administrative expenses as a percentage of total expenses 
remained relatively constant at approximately 20% and 18% for the three- and 
nine-month periods ended September 30, 1997 and approximately 18% and 17% for 
the comparable periods in 1996.  The Company expects its general and 
administrative costs will increase for the remainder of 1997 in absolute 
dollars when compared to 1996 in order to provide corporate support for 
expanding research and development efforts.

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

Interest income and expense

Interest income decreased to $745,000 for the three-months ended September 
30, 1997, from $879,000 for the same period in 1996 and increased to $2.5 
million for the nine-months ended September 30, 1997 from $2.2 million for 
the same period in 1996.  The decrease for the three-months ended September 
30, 1997 compared to the same period in 1996 was primarily due to the 
decrease in average cash balances between the periods.  The increase for the 
nine-months ended September 30, 1997 compared to the same period in 1996 was 
primarily due to the increase in average cash balances between the periods, 
resulting from receipt of net proceeds of approximately $36 million from the 
public offering of 3,000,000 shares of the Company's Common Stock which 
closed on March 27, 1996, and approximately $5.5 million from the exercise on 
April 24, 1996 by the underwriters of the over allotment option of 450,000 
shares in the public offering.  The receipt of up-front fees collected under 
new collaborations, proceeds from research funding and collection of revenues 
from the shipment of compounds under the collaboration with PNU have helped 
to sustain the cash levels.  Interest expense increased to $325,000 for the 
three-month period ended September 30, 1997, from $208,000 for the same 
period in 1996, and increased to $707,000 for the nine-months ended September 
30, 1997, from $486,000 for the same period in 1996.  The increase for the 
three- and nine-month periods  ended September 30, 1997 was the result of 
higher debt balances primarily from the previous line of credit with Bank of 
America.  The Company has only used draw downs from that line for capital 
acquisitions during the nine-months ended September 30, 1997.  The Company 
expects interest expense to fluctuate as financing needs change for further 
expansion of the Company's facilities and acquisition of lab equipment.

LIQUIDITY AND CAPITAL RESOURCES

The Company has financed its operations since inception primarily through 
private and public offerings of its Capital Stock and through corporate 
collaborations.  As of September 30, 1997, the Company had realized 
approximately $92.5 million in net proceeds from offerings of its Capital 
Stock. In addition, the Company has realized $75 million from its corporate 
collaborations (excluding the $5.4 million equity investment in the Company 
made by PNU). 

The Company's principal sources of liquidity are its cash and investments, 
which totaled $56.3 million as of September 30, 1997.  In September 1997, the 
Company entered into a new credit agreement with Sumitomo Bank, Limited and 
Silicon Valley Bank jointly, for borrowings up to  $20 million.  As of 
September 30, 1997 the Company had borrowed $11.8 million and had $8.2 
million remaining available under this agreement.

Net cash used in operating activities during the nine-month period ended 
September 30, 1997 was $10.6 million compared to $6.2 million in the same 
period in 1996.  The increase was primarily due to the increase in net loss 
for the nine months ended September 30, 1997 and the timing of cash received 
under the Company's collaboration agreements.  Cash used in operating 
activities is expected to fluctuate from quarter to quarter depending, in

timing and amounts, if any, of cash received from existing and any new 
collaboration agreements.

The Company also spent approximately $5.4 million for the purchase of 
property, plant and equipment during the nine months ended September 30, 
1997.  Additional equipment will be needed as the Company increases its 
research and development activities.  The Company received net financing of 
$4.1 million, which was comprised of borrowings under existing credit 
instruments and payments under lease agreements, during the nine-months ended 
September 30, 1997.

The Company's revenues presently are attributable to collaborations with PNU, 
Amgen, Bayer SB, Merck and Abbott. The research phase of the Amgen 
erythropoeitin collaboration ended in February 1997.  The proof of concept 
phase of the SB collaboration has been extended through the end of 1997 and 
can be extended by SB for an additional six month period, at which time it 
may enter into a research phase. The human growth hormone collaboration with 
PNU and research support of the Bayer collaboration for an oral tryptase 
inhibitor extends through the fourth quarter of 1997.  The research support 
for the Factor Xa program with PNU and the osteoporosis program with Merck 
extends through third and fourth quarters of 1998, respectively. The 
Combinatorial Chemistry collaboration with PNU extends beyond the next 12 
months.  If the Company is unable to renew or replace any of these 
collaborations or extend the SB collaboration into the research phase, such 
events may have a material adverse effect on the Company's business and 
financial condition.

The Company expects that its existing capital resources, including research 
and development revenues from existing collaborations, will enable the 
Company to maintain current and planned operations through at least the next 
42 months. The Company may need to raise substantial additional capital to 
fund its operations beyond the end of such period.  The Company expects that 
it will seek such additional funding through new collaborations, through the 
extension of existing collaborations or through public or private equity or 
debt financing.

There can be no assurance that additional financing will be available on 
acceptable terms or at all.  Any additional funds raised by issuing equity 
securities, may result in further dilution to stockholders.  If adequate 
funds are not available, the Company may be required to delay, to reduce the 
scope of or to eliminate one or more of its research or development programs 
or to obtain funds through arrangements with collaborative partners or others 
that may require the Company to relinquish rights to certain of its 
technologies or products that the Company would otherwise seek to develop or 
commercialize itself.

RECENT EVENTS
                                           
On November 3, 1997 the Company announced that it had signed a definitive 
agreement with Sequana Therapeutics, Inc. ("Sequana"), pursuant to which the 
Company will acquire all

of the outstanding stock of Sequana based on an exchange ratio of 1.35 shares 
of the Company's common stock for each share of Sequana.  The combined 
Company is proposed to be renamed AxyS Pharmaceuticals, Inc. and will trade 
on the Nasdaq National Market System.  The acquisition is valued at 
approximately $166 million, will be accounted for as a "purchase" and is 
expected to result in a substantial charge related to "in-process" technology 
when the transaction is completed, which is currently expected to take place 
in early 1998.  The transaction is expected to qualify as a tax-free 
reorganization and has been approved by the Boards of Directors of both 
corporations. The transaction must be approved by the stockholders of each 
company. Certain stockholders owning approximately 19% of the outstanding 
Common Stock of Sequana have agreed to vote their shares in favor of the 
transaction. The completion of the transaction is subject to certain risks, 
including, but not limited to, the potential inability to complete the merger 
as scheduled, or at all, potential problems associated with integrating the 
two companies, including the risk that key employees will choose to leave, 
acceptance of the combined companies by corporate partners of each company, 
some of whom will have the right to terminate their collaborations as the 
result of the merger, acceptance of the merger by the stockholders of each 
company and by the market, as well as those associated with the ongoing 
businesses of each company as discussed in their respective SEC filings.

CERTAIN BUSINESS RISKS 

The Company is at an early stage of development.  The Company's technologies 
are, in many cases, new and all are still under development.  All of the 
Company's proposed products are in research or development and will require 
significant additional research and development efforts prior to any 
commercial use, including extensive preclinical and clinical testing as well 
as lengthy regulatory approval.  There can be no assurance that the Company's 
research and development efforts will be successful, that any of its proposed 
products will prove to be safe and efficacious in the clinical trials or that 
any commercially successful products will ultimately be developed by the 
Company.  In addition, many of the Company's currently proposed products are 
subject to development and licensing arrangements with the Company's 
collaborators.  Therefore, the Company is dependent on the research and 
development efforts of these collaborators.  Moreover, the Company is 
entitled only to a portion of the revenues, if any, realized from the 
commercial sale of any of the proposed products covered by the 
collaborations.  The Company has experienced significant operating losses 
since its inception and expects to incur significant operating losses over at 
least the next several years.  The development of the Company's technology 
and proposed products will require a commitment of substantial funds to 
conduct these costly and time consuming activities.  All of the Company's 
revenues to date have been received pursuant to the Company's collaborations.

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


Should the Company or its collaborators fail to perform in accordance with 
the terms of their agreements, any consequent loss of revenue under the 
agreements could have a material adverse effect on the Company's results of 
operations. The proposed products under development by the Company have never 
been manufactured on a commercial scale and there can be no assurance that 
such products can be manufactured at a cost or in quantities necessary to 
make them commercially viable.  The Company has no sales, marketing or 
distribution capability.  If any of its products subject to collaborative 
agreements are successfully developed, the Company must rely on its 
collaborators to market such products.  
                                           
If the Company develops any products which are not subject to collaborative 
agreements, it must either rely on other pharmaceutical companies to market 
such products or must develop a marketing and sales force with technical 
expertise and supporting distribution capability in order to market such 
products directly.  

The foregoing risks reflect the Company's early stage of development and the 
nature of the Company's industry and products.  Also inherent in the 
Company's stage of development is a range of additional risks, including 
competition, uncertainties regarding protection of patents and proprietary 
rights, government regulation and uncertainties regarding health care reform. 
These risks and uncertainties are discussed further in "Item 1. - Business - 
Business Risks" on Form 10-K for the year ended December 31, 1996, filed by 
the Company March 31, 1997.
