3.    PER SHARE INFORMATION

      Net income (loss) per share is computed using the weighted average number
of shares of common stock outstanding during the periods presented. Common
equivalent shares are included in the computation for income periods and
excluded from the computation for loss periods as their effect is antidilutive,
except that, pursuant to the Securities and Exchange Commission Staff Accounting
Bulletins, common and common equivalent shares (stock options, warrants, and
convertible preferred stock) issued during the 12 month period prior to the
Company's initial public offering have been included in the calculation as if
they were outstanding for all periods through March 31, 1996 (using the treasury
stock method for stock options and warrants and the if-converted method for
convertible preferred stock). 

      The pro forma calculation of net income (loss) per share has been computed
as described above but also gives retroactive effect from the date of issuance
to the conversion of the convertible preferred stock which automatically
converted to common shares upon closing of the Company's initial public offering
in May 1996.

      In February 1997, the Financial Accounting Standards Board issued
Statement 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 primary earnings per share, the
dilutive effect of stock options will be excluded. The impact is not expected to
result in a change in primary earnings per share for the three and six months
ended June 30, 1997 and the three months ended June 30, 1996 as the Company
incurred net losses in these periods and, accordingly, the calculation of
earnings per share for these periods excluded stock options as their effect was
antidilutive. The impact for the six months ended June 30, 1996 resulted in no
change in primary earnings per share.

4.    SUBSEQUENT EVENTS

      In July 1997, the Company signed a 30 month agreement to sublease two
buildings, each building consisting of approximately 18,000 square feet of
additional research and office space. The agreement calls for total minimum
monthly rental payments ranging from $62,000 to $64,000 beginning on November 1,
1997. The Company intends to temporarily sublease one building and to utilize
the other building for additional research and administrative space.

         MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
                              RESULTS OF OPERATIONS

OVERVIEW

      As part of the Company's strategy to enhance its research and development
capabilities and to fund, in part, its capital requirements, Microcide has
entered into collaborative agreements with three major pharmaceutical companies.
The Company has received license fees, research support payments and milestone
payments pursuant to these agreements and can potentially receive additional
research support payments, additional milestone payments and royalty payments.
License payments are typically nonrefundable up-front payments for licenses to
develop, manufacture and market products, if any, that are developed as a result
of the collaboration. Research support payments are typically contractually
obligated payments to fund research and development over the term of the
collaboration. Milestone payments are payments contingent upon the achievement
of specified milestones, such as selection of candidates for drug development,
the commencement of clinical trials or receipt of regulatory approvals. If drugs
are successfully developed and commercialized as a result of the collaborative
agreements, the Company will receive royalty payments based upon the net sales
of such drugs.

      In June 1997, Microcide signed an agreement to provide Daiichi
Pharmaceutical Co., Ltd. with a subset of its synthetic molecular diversity
collection for use in Daiichi's own drug discovery screening programs in
consideration for future payments by Daiichi of $1.5 million. Delivery of the
compounds, receipt of the associated payments and recognition of related
revenues are expected to occur during the second half of 1997. In July 1997,
Microcide signed a one-year agreement to provide a minimum of 40,000 extracts
from its natural products diversity collection to Tularik Inc. for use in
Tularik's non-antimicrobial drug discovery screening programs. Pursuant to the
agreement, Microcide will receive payments for the extracts upon delivery to
Tularik, may provide refermentation of extracts for agreed upon amounts and may
potentially receive license fees and royalties on resulting products.

      Through June 30, 1997, the Company had received in the aggregate $24.5
million in license fees, milestone payments and research support payments under
the collaborative agreements. Assuming none of the existing collaborative
agreements is terminated prior to its scheduled expiration, the Company will be
entitled to receive up to an additional $23.0 million of research support
payments. In addition, in the event that any of the collaborative agreements are
extended beyond their current terms, the Company will be entitled to receive
additional research support payments.

      In the event that the Company achieves the specified research and product
development milestones, the Company will be entitled to receive milestone
payments under its collaborative agreements with three major pharmaceutical
companies ranging from $13.0 million to $32.5 million per product. No royalty
payments have yet been received and the Company does not expect to receive
royalties based upon the net sales of drugs for a significant number of years,
if ever.

      Quarterly results of operations are subject to significant fluctuations
based on the timing and amount of certain revenues earned under the
collaborative agreements. The Company expects to incur operating losses in the
future.

      This Form 10-Q contains forward-looking statements based upon current
expectations, including statements with regard to the potential receipt of
additional research support payments, milestone payments and royalties from the
Company's collaborative partners, payments related to delivering molecular
diversity samples to Daiichi and Tularik, and the period of time the Company's
existing capital resources and future payments under collaborative agreements
will be sufficient to satisfy the Company's funding requirements, expectations
concerning the Company's future research and development and general and
administrative expenses and future facility needs. Such forward-looking
statements involve risk and uncertainties, including without limitation, the
risk that the Company's collaborations will be terminated, development
candidates will not be identified, development candidates which are selected
will not proceed through pre-clinical trials or will not prove safe and
effective for treatment of humans in clinical trials, or that the
identification, selection, pre-clinical, and clinical testing of development
candidates will take substantially longer or be substantially more expensive
than contemplated by the Company, or that the Company will not be able to obtain
on a timely basis government regulatory clearance required for clinical testing,
manufacturing, and marketing of its products, and the other risks and
uncertainties set forth in the Company's annual report on Form 10-K for the year
ended December 31, 1996. Actual results and timing of certain events could
differ materially from those indicated in the forward-looking statements as a
result of these or other factors.

RESULTS OF OPERATIONS

THREE MONTHS ENDED JUNE 30, 1997 AND 1996

Revenues. Total revenues for the second quarter of 1997 were $3.0 million, an
increase of 34% from the $2.2 million in revenues recognized in the second
quarter of 1996. There were no license and milestone fees earned for either
period. Research support revenue increased in the second quarter of 1997 due
primarily to higher revenues earned from the Pfizer and Daiichi collaborative
agreements resulting from an increase in the number of research personnel
devoted to the collaborative projects, as well as an increase in reimbursable
research expenses, such as costs related to certain equipment and outside
consulting services.

Research and Development Expenses. Research and development expenses for the
second quarter increased approximately 88% from $2.3 million in 1996 to $4.3
million in 1997. The increases are due primarily to higher compensation and
other employee-related expenses associated with an increase in headcount to
support the Company's corporate collaborations and its internal programs, higher
spending for research supplies and materials, higher expenses related to
assembling the Company's molecular diversity collection, higher costs relating
to expanded research and development facilities and higher expenses for outside
consulting services. Research and development expenses are expected to further
increase in the third quarter as the Company continues to add research personnel
to support its corporate collaborations and internal programs.

General and Administrative Expenses. General and administrative expenses for the
second quarter increased 89% from $581,000 in 1996 to $1.1 million in 1997.
Increased expenses primarily consisted of higher compensation expenses due to an
increase in administrative personnel and higher costs for legal and other
outside services associated with being a public company. General and
administrative expenses may continue to increase in dollar amounts in the next
quarter, but are expected to be at a lower percentage of total operating
expenses.

Interest Income and Expense. Interest income for the second quarter increased
from $416,000 in 1996 to $650,000 in 1997, primarily due to an increase in
average cash balances in 1997 related to proceeds received from the Company's
initial public offering in May 1996, proceeds received from the sale of other
equity and cash received under 


                                      -9-
   10
collaborative agreements. Interest expense for the second quarter decreased from
$50,000 in 1996 to $40,000 in 1997 due to a decrease in capital lease balances
outstanding.

SIX MONTHS ENDED JUNE 30, 1997 AND 1996

Revenues. Total revenues for the first half of 1997 were $7.1 million, an
increase of 46% from the $4.9 million in revenues for the first half of 1996.
License and milestone fees were $1.0 million in each period. Research support
revenue increased from $3.9 million in the first half of 1996 to $6.1 million in
the first half of 1997 due primarily to higher revenues earned from the Pfizer
and Daiichi collaborative agreements resulting from an increase in the number of
research personnel devoted to the collaborative projects, as well as an increase
in reimbursable research expenses, such as costs related to certain equipment
and outside consulting services.

Research and Development Expenses. Research and development expenses for the
first half of 1997 were $8.4 million, an increase of approximately 107% from
$4.1 million in the first half of 1996, primarily due to increased compensation
and other employee-related expenses associated with an increase in headcount to
support the Company's corporate collaborations and its internal programs, higher
spending for research supplies and materials, higher expenses related to
assembling the Company's molecular diversity collection, higher costs relating
to expanded research and development facilities and higher expenses for outside
consulting services. Research and development expenses are expected to further
increase in the second half of 1997 as the Company continues to add research
personnel to support its corporate collaborations and internal programs.

General and Administrative Expenses. General and administrative expenses for the
first half of 1997 increased approximately 92% from $1.1 million in 1996 to $2.1
million in 1997. Increased expenses primarily consisted of higher compensation
expenses due to an increase in administrative personnel and higher costs for
legal and other outside services associated with being a public company. General
and administrative expenses may continue to increase in dollar amounts in the
second half of 1997 as compared to the first half of 1997, but are expected to
be at a lower percentage of total operating expenses.

Interest Income and Expense. Interest income for the first half of 1997
increased from $553,000 in 1996 to $1.3 million in 1997, primarily due to an
increase in average cash balances in 1997 related to proceeds received from the
Company's initial public offering in May 1996, proceeds received from the sale
of other equity and cash received under collaborative agreements. Interest
expense for the first half of 1997 decreased from $123,000 in 1996 to $93,000 in
1997 due to a decrease in capital lease balances outstanding.


LIQUIDITY AND CAPITAL RESOURCES

      The Company has financed its operations since inception primarily through
the sale of equity, through funds provided under collaborative agreements and
through equipment financing. As of June 30, 1997 the Company had received
approximately $64.2 million in net proceeds from the sale of equity and
approximately $24.5 million from license and milestone fees and research support
payments under collaborative agreements.

      Cash, cash equivalents and short-term investments at June 30, 1997 were
$44.1 million compared to $47.5 million at December 31, 1996. Net cash used in
the Company's operations was $1.7 million for the first half of 1997. Net cash
used in investing activities was $2.0 million, of which $1.3 million was capital
expenditures and $725,000 was purchases of investments in excess of maturities
of investments. Net cash used in financing activities was $421,000, of which
$582,000 was principal payments on capital lease obligations.

buildings, each building consisting of approximately 18,000 square feet of
additional research and office space. The agreement calls for total minimum
monthly rental payments ranging from $62,000 to $64,000 beginning on November 1,
1997. The additional buildings are adjacent to the Company's principal offices.
The Company intends to temporarily sublease one building and to utilize the
other building for additional research and administrative space. It is expected
that the additional space will support the Company's expansion activities
through 1999. 

      The Company believes that its existing capital resources, interest income
and future payments due under collaborative agreements will enable the Company
to maintain current and planned operations at least through 1998.
