                     FOR THE ANNUAL MEETING OF STOCKHOLDERS
                          TO BE HELD ON APRIL 13, 1999
                            ------------------------
 
                 INFORMATION CONCERNING SOLICITATION AND VOTING
 
GENERAL
 
     The Board of Directors of Genentech, Inc. ("Genentech" or the "Company")
hereby solicits your proxy for use at the Annual Meeting of Stockholders to be
held on Tuesday, April 13, 1999 (the "Annual Meeting"), or at any adjournment or
postponement of the Annual Meeting, for the purposes set forth in the foregoing
Notice of Annual Meeting of Stockholders. Copies of solicitation material will
be furnished to brokerage houses, fiduciaries and custodians to forward to
beneficial owners of Callable Putable Common Stock of Genentech, par value $0.02
per share ("Special Common Stock"), held in their names. The cost of
solicitation of proxies, including expenses in connection with preparing and
mailing this Proxy Statement, will be borne by Genentech. In addition, Genentech
will reimburse brokerage firms and other persons representing beneficial owners
of Special Common Stock for their expenses in forwarding solicitation material
to such beneficial owners. Original solicitation of proxies by mail may be
supplemented by telephone, telegram, internet and personal solicitation by
directors, officers or other regular employees of Genentech. No additional
compensation will be paid to directors, officers or other regular employees for
such services. This Proxy Statement and accompanying Proxy Card will be mailed
on or about March 2, 1999 to all stockholders entitled to vote at the Annual
Meeting.
 
VOTING RIGHTS AND OUTSTANDING SHARES
 
     Stockholders of record at the close of business on February 16, 1999 (the
"Record Date") will be entitled to notice of and to vote at the Annual Meeting.
On the Record Date, Genentech had outstanding 51,131,075 shares of Special
Common Stock and 76,621,009 shares of Common Stock, par value $0.02 per share
("Common Stock"). Each holder of record of shares of Special Common Stock or
Common Stock on the Record Date is entitled to one vote per share on each matter
to be considered at the Annual Meeting. An affirmative vote of a majority of the
shares present in person or represented by proxy and entitled to vote is
required for approval of all matters being submitted to the stockholders for
their consideration. All votes will be tabulated by the inspector of elections
appointed for the Annual Meeting, who will separately tabulate affirmative and
negative votes, abstentions and broker nonvotes. Abstentions and broker nonvotes
are each included in the number of shares present and voting. However,
abstentions will be counted toward the tabulations of votes cast on proposals
presented to the stockholders and will have the same effect as negative votes,
whereas broker nonvotes will not be counted for purposes of determining whether
a proposal has been approved or not.
 
     Any stockholder giving a proxy has the power to revoke it any time before
it is exercised, whether the proxy was given by telephone, via the internet or
by returning the Proxy Card. The proxy may be revoked by filing with the
Secretary of Genentech, at the principal executive office of Genentech, 1 DNA
Way, South San Francisco, California 94080, a notice of revocation or a duly
executed Proxy Card bearing a later date, or by making an authorized internet or
telephone communication on a later date in accordance with the instructions on
the enclosed Proxy Card. It may also be revoked by attendance at the Annual
Meeting and voting in person.

RELATIONSHIP WITH ROCHE HOLDINGS, INC.
 
     On October 25, 1995 (the "Effective Date"), a wholly-owned subsidiary
("Merger Subsidiary") of Roche Holdings, Inc., a Delaware corporation ("Roche"),
was merged with and into Genentech (the "Merger") pursuant to the Agreement and
Plan of Merger, dated as of May 23, 1995, as amended and restated, among
Genentech, Roche and Merger Subsidiary (the "Merger Agreement"). Roche is a
wholly-owned subsidiary of Roche Finance Ltd, a Swiss corporation, which is a
wholly-owned subsidiary of Roche Holding Ltd, a Swiss corporation ("Roche
Holding"). On the Effective Date, (i) each outstanding share of Common Stock,
par value $.02 per share, of Genentech (other than shares of Common Stock held
by Roche and its affiliates) was converted into one share of Special Common
Stock, (ii) each outstanding share of Common Stock held by Roche and its
affiliates was cancelled, and (iii) the outstanding common stock of Merger
Subsidiary was converted into shares of Common Stock representing the same
number of shares of Common Stock held by Roche and its affiliates immediately
prior to the Merger. Immediately following the Merger, Roche and its affiliates
owned 76,621,009 shares of Common Stock.
 
     On the Effective Date, Genentech's Certificate of Incorporation was amended
to provide that in accordance with the terms of the Amended Governance Agreement
(as defined below) Roche could cause Genentech to redeem the Special Common
Stock at predetermined prices. During the quarter beginning January 1, 1999, the
option price is $81.00 per share, and it increases on April 1, 1999 by $1.50 per
share to $82.50 per share for the final quarter of the redemption period, which
ends on June 30, 1999 (the "Call Rights"). In accordance with Genentech's
Certificate of Incorporation, for 30 business days following the expiration of
the redemption period or during the 60 business days following certain
insolvency events involving Genentech (the "Put Period"), the stockholders will
have the right to cause the purchase of none, some or all of their shares of
Special Common Stock at $60.00 per share (the "Put Rights"). Genentech's
obligation to redeem these shares is contingent upon the contribution by Roche
of the necessary redemption funds.
 
     On the Effective Date, Genentech and Roche entered into the Amended and
Restated Governance Agreement (the "Amended Governance Agreement"), which
contains terms relating to the corporate governance of the Company after the
Merger and the acquisition and disposition of securities of the Company by Roche
and its affiliates. The Amended Governance Agreement provides that following the
Put Period, the Board shall include two Roche designees, two officers of the
Company and the remainder shall be "independent directors" (defined as
individuals who are neither an officer of Genentech nor an employee, director,
principal stockholder or partner of Roche, its affiliates or any entity (other
than the Company and its subsidiaries) that was dependent on Roche or its
affiliates for more than 10% of its revenues or earnings in the most recent
fiscal year). Roche may also designate a number of such independent directors
equal to its voting interest of Genentech capital stock times the total number
of such independent directors. Prior to the end of the Put Period, Roche may not
designate more than two representatives to the Board (currently Drs. Humer and
Knowles) unless it acquires 100% ownership of Genentech. The Amended Governance
Agreement required the establishment of a Nominations Committee with exclusive
authority to nominate individuals to serve on the Board. The Nominations
Committee must have at least one director designated by Roche, one director who
is an officer of the Company and one independent director, and all nominations
for members of the Board who are not then serving as directors must be
unanimous, except for representatives designated by Roche pursuant to the terms
of the Amended Governance Agreement. Roche also agreed to provide the funds
necessary to satisfy the financial obligations regarding the Call Rights or the
Put Rights, as applicable. Roche Holding unconditionally guaranteed Roche's
payment obligations for the Put Rights under the terms of the Guaranty Agreement
dated as of the Effective Date between Genentech and Roche Holding.
 
     The Amended Governance Agreement specifies that the approval of the
directors of the Company designated by Roche under the Amended Governance
Agreement is required for the acquisition, sale, lease, license or transfer of
all or a substantial portion of the business or assets of the Company and
certain issuances and redemptions of capital stock of the Company. In addition,
the Amended Governance Agreement provides that the Company will not, except as
provided in the License Agreement (as defined below), enter into any material
licensing or marketing agreement for any products, processes, inventions or
developments made by the Company or its subsidiaries unless the Company has
first negotiated in good faith with Roche for not less
                                        2
   5
 
than three nor more than six months with a view toward reaching a mutually
beneficial licensing or marketing agreement.
 
     On the Effective Date, Genentech and F. Hoffmann-La Roche Ltd, a Swiss
corporation ("HLR"), entered into an Agreement (the "License Agreement")
granting HLR an option for ten years for licenses to use and sell certain of
Genentech's products in non-U.S. markets. In the second quarter of 1997 and the
second and fourth quarters of 1998, the Company and HLR agreed in principle to
changes to the License Agreement. Key changes to the License Agreement are
summarized as follows: (1) For future products, HLR may choose to exercise its
option either when the Company determines to move a product into development, or
at the end of Phase II clinical trials (as in the License Agreement). U.S. and
European development costs will be shared (discontinuing the distinction
regarding location or purpose of studies). (2) If HLR exercises its option at
the development determination point, U.S. and European development costs will be
shared 50/50. (3) If HLR exercises its option at the end of Phase II clinical
trials, HLR will reimburse the Company for 50% of any development costs
incurred, and subsequent U.S. and European development costs will be shared
75/25, HLR/Genentech. (4) For nerve growth factor (NGF), which HLR has already
exercised its option to develop, prospective U.S. and European development costs
will be shared 60/40, HLR/Genentech. (5) HLR has assumed development of
Xubix(TM), an oral IIb/IIIa antagonist, globally on its own. The Company may
subsequently opt-in and join development at any time up to 30 days after the New
Drug Application ("NDA") approval for the first indication. The Company and HLR
also agreed that if the Company chooses to opt-in, it will make a payment to HLR
of $25 million, and it will reimburse HLR for 50% of the U.S. and European
IIb/IIIa development costs incurred from May 1, 1997 to the opt-in date. HLR and
Genentech will co-promote Xubix(TM) in the U.S. with a 60/40, Genentech/HLR,
profit-sharing if the NDA approval for the first indication is for acute therapy
or a 50/50 profit-sharing if the NDA approval for the first indication is for
chronic therapy. If the Company does not opt-in, it will receive from HLR a 6%
royalty on worldwide sales of Xubix(TM).
 
     In general, with respect to the Company's products, HLR pays a royalty of
12.5% until a product reaches $100 million in aggregate sales outside of the
U.S., at which time the royalty rate on all sales increases to 15%. In addition,
HLR has rights to, and pays the Company 20% royalties on, Canadian sales of
Activase(R) (Alteplase, recombinant) tissue plasminogen activator, Protropin(R)
(somatrem for injection) growth hormone, Nutropin(R) [somatropin (rDNA origin)
for injection] growth hormone, Pulmozyme(R) (dornase alfa, recombinant)
inhalation solution and Actimmune(R) (interferon gamma-1b); sales of
Pulmozyme(R) inhalation solution outside of the U.S.; and sales of Rituxan(TM)
(Rituximab) outside of the U.S., excluding Japan. HLR currently has the right to
sell Pulmozyme(R) and pays royalties to the Company on such sales. The Company
supplies its products to HLR, and has agreed to supply products for which HLR
has exercised its option, for sales outside of the U.S. at cost plus 20%.

STOCKHOLDER PROPOSALS
 
     1999 Annual Meeting. Notice of any stockholder proposal that is intended to
be presented by such stockholder at Genentech's 1999 Annual Meeting must be
received by the Secretary of the Company no later than the close of business on
March 12, 1999, pursuant to the Company's Bylaws. The Bylaws require that notice
of any stockholder proposal be received by the Secretary of the Company not less
than 90 days prior to the meeting, unless fewer than 100 days' notice of the
meeting date is given or made to stockholders, in which case notice of any
stockholder proposal must be received not later than the close of business on
the 10th day following the day on which notice of the meeting date was given
(the "Bylaw Deadline"). Any notice of a stockholder proposal must set forth in
writing as to each matter the stockholder proposes to bring before the Annual
Meeting (a) a brief description of the business desired to be brought before the
Annual Meeting and the reasons for conducting such business at the Annual
Meeting, (b) the name and address, as they appear on the Company's books, of the
stockholder proposing such business, (c) the class and number of shares of the
Company that are beneficially owned by the stockholder and (d) any material
interest of the stockholder in such business. Stockholders are advised to review
the Company's Bylaws for the requirements regarding stockholder proposals.
 
     The Company has not been notified by any stockholder of his or her intent
to present a stockholder proposal at this year's Annual Meeting. Stockholders'
proxies may confer discretionary authority to vote on any matter properly
brought before the Annual Meeting, including any stockholder proposals received
between the date of this Proxy Statement and the Bylaw Deadline for this year's
Annual Meeting, which is March 12, 1999.
 
     2000 Annual Meeting. Notice of any stockholder proposal that is intended to
be presented by such stockholder at Genentech's 2000 Annual Meeting and included
in the Proxy Statement relating to that meeting must be received by the
Secretary of the Company no later than November 3, 1999 in order that it may be
considered for possible inclusion in the Proxy Statement and the form of Proxy
Card relating to that meeting.
 
     With respect to a stockholder proposal that is not intended to be included
in such Proxy Statement, if the Secretary of the Company does not receive notice
of such stockholder proposal by January 17, 2000, stockholders' proxies may
confer discretionary voting authority to the Company to vote proxies in the
discretion of the proxy holders on that proposal even if it is not specifically
reflected on the Proxy Card and stockholders have not had an opportunity to vote
on it by proxy. If a stockholder wishes to present a proposal at the Company's
2000 Annual Meeting and the proposal is not intended to be included in the Proxy
Statement relating to that meeting, the stockholder must give advance notice to
the Company prior to the Bylaw Deadline for such meeting determined in
accordance with the Bylaws, as described above. If a stockholder gives notice of
such a proposal after the Bylaw Deadline, the stockholder will not be permitted
to present the proposal to the stockholders for a vote at the meeting.
Stockholders are advised to review the Company's Bylaws for the requirements
regarding stockholder proposals.

                      PROPOSAL 1 -- ELECTION OF DIRECTORS
 
NOMINEES
 
     Genentech has three classes of directors serving staggered three-year
terms. The 2002 class consists of three directors, the 2001 class consists of
five directors and the 2000 class consists of two directors. The 2002 class
directors are to be elected at the Annual Meeting for three-year terms expiring
on the date of the Annual Meeting in 2002 or until each such director's
successor shall have been duly elected or appointed. It is intended that the
shares represented by proxies will be voted for the election of Messrs. Munro,
Smith and Tappan, each of whom is currently a member of the Board of Directors
of Genentech, as the 2002 class directors, unless the proxy withholds authority
to vote for any of them. Under the terms of the Amended Governance Agreement,
Roche agreed that in connection with the election of directors it would vote any
of its shares of Common Stock and Special Common Stock in proportion to the
votes cast by the other holders of Special Common Stock; provided, however,
Roche may cast all of its votes for any director nominee of Roche designated
under the Amended Governance Agreement. Drs. Knowles and Humer were previously
elected to the Board of Directors as Roche's nominees. The directors are elected
by a plurality of the votes of the Common Stock and Special Common Stock, voting
together as a single class, present in person or represented by proxy and
entitled to vote at the Annual Meeting.
 
           THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR EACH NOMINEE
 
     In the event any of such nominees becomes unable or unwilling to serve, the
shares represented by the proxies will be voted for the election of the balance
of those named and such other person as the Board of Directors may select. The
Board of Directors has no reason to believe that any such nominee will be unable
to serve.
 
     The following table sets forth the name and age (as of the date of the
Annual Meeting) of each of the directors, the class to which each has been
nominated for election or elected, their principal occupations at present, the
positions and offices held by each with Genentech in addition to the position as
a director, and the period during which each has served as a director of
Genentech.

(other than certain special committees) will at all times include at least one
director designated by Roche. The director designated by Roche to serve on any
committee will be entitled to designate as his or her alternate another director
designated by Roche.
 
     In 1998, the Audit Committee was comprised of Dr. Knowles and Messrs.
Murfin, Smith and Tappan. Dr. Humer served on the Audit Committee until February
1998, when he resigned from such committee and Dr. Knowles was appointed to

and provides a direct line of communication between the auditors and the Board.
The Audit Committee, with and without Company management present, meets with the
Company's independent auditors to review and discuss various
 
                                        7
   10
 
matters, including Genentech's financial statements, the quarterly reporting
process and management's control thereof, the inventory and receivable reserve
policies, the tax compliance program and strategy, the scope of external and
general audit activities, the independent auditor's fees and performance, the

practices and procedures.
 
     In 1998, the Compensation Committee was comprised of Ms. Levinson, Drs.
Humer and Boyer, and Mr. Munro, none of whom is an employee of Genentech. The
Compensation Committee administers Genentech's stock option plans, the stock
purchase plan and other corporate benefits programs. The Compensation Committee
also reviews and approves the annual bonus plan, bonus plan payouts, annual

policies and compliance, investor relations, corporate communications,
government relations, human resources, legal and regulatory affairs, compliance
with laws and regulations, and Board of Directors and Board committee
effectiveness.
 
     In 1998, the Executive Committee was comprised of Drs. Boyer, Humer and
Levinson and Mr. Munro. The Executive Committee was established to act when the
full Board of Directors is unavailable. It has all the authority of the Board in
the management of the business and affairs of Genentech, except those powers
that by law cannot be delegated by the Board of Directors.
 
     In 1998, the Nominations Committee was comprised of Ms. Levinson and Drs.
Boyer, Knowles and Levinson. The purpose of the Nominations Committee is to
identify, review and recommend potential nominees to the Board of Directors of
Genentech, and to recommend executive officers of the Company for election as
executive officers by the Board of Directors. The Nominations Committee will
consider nominees to the Board of Directors recommended by Genentech
stockholders. To be considered, stockholders wishing to nominate a person to the
Board of Directors should send a letter to the Secretary of Genentech that
complies with the notification requirements of Genentech's Bylaws. Each
stockholder of Genentech is also entitled to nominate candidates for director at
the Annual Meeting if such stockholder has given timely notice in proper written
form of his intent to make such nomination or nominations. To be timely, a
stockholder's notice must be received by the Secretary of the Company not later
than 90 days prior to the meeting, unless fewer than 100 days' notice of the
meeting date is given to stockholders, in which case a stockholder's notice must
be received not later than the close of business on the 10th day following the
day on which notice of the meeting date was given. Any stockholder's notice
regarding director nominations must set forth: (a) the name and address of the
stockholder who intends to make the nomination and of the person or persons to
be nominated, (b) a representation that the stockholder is a holder of record of
stock of the Company entitled to vote at such meeting to and intends to appear
in person or by proxy at the meeting to nominate the person or persons specified
in the notice, (c) a description of all arrangements or understandings between
the stockholder and each nominee and any other person or persons (naming such
person or persons) pursuant to which the nomination or nominations are to be
made by the stockholder, (d) such other information regarding each nominee
proposed by such stockholder as would be required to be included in a proxy
statement filed pursuant to the proxy rules of the Securities and Exchange
Commission had the nominee been nominated, or intended to be nominated, by the
Board of Directors, and (e) the consent of each nominee to serve as a director
of the corporation if so elected.

              PROPOSAL 2 -- AMENDMENT OF 1991 EMPLOYEE STOCK PLAN
 
     In December 1990, the Board of Directors adopted the 1991 Employee Stock
Plan under which 1,500,000 shares of the Company's Common Stock were initially
reserved for issuance; in April 1991, Genentech's stockholders approved the
plan. The 1991 Employee Stock Plan, as amended through the date hereof, shall
hereinafter be referred to as the "1991 Plan." Genentech believes that the 1991
Plan is an important part of providing incentives and retaining employees. In
December 1992, the Board of Directors approved amendments to the 1991 Plan to
(i) increase the number of shares of Common Stock available for issuance under
the 1991 Plan by an additional 1,400,000 shares to a total of 2,900,000 shares
and (ii) increase the maximum number of shares of Common Stock that may be
purchased by all participating employees under the 1991 Plan during any calendar
quarter in which Genentech pays a regular annual bonus from 180,000 shares to
200,000 shares. In May 1993, Genentech's stockholders approved such amendments.
In February 1995, the Board of Directors approved an amendment to the 1991 Plan
to increase the number of shares of Common Stock available for issuance under
the 1991 Plan by an additional 900,000 shares to a total of 3,800,000 shares. In
April 1995, Genentech's stockholders approved such amendment. In December 1996,
the Board of Directors approved an amendment to the 1991 Plan to increase the
number of shares of Special Common Stock available for issuance under the 1991
Plan by an additional 700,000 shares to a total of 4,500,000. In April 1997,
Genentech's stockholders approved such amendment. In December 1998, the Board of
Directors approved an amendment to the 1991 Plan to increase the number of
shares of Special Common Stock available for issuance under the 1991 Plan by an
additional 800,000 shares to a total of 5,300,000 (the "1999 Amendment"). The
Board of Directors has adopted the 1999 Amendment to ensure that Genentech has
shares available under the 1991 Plan to provide continued incentives to its
employees through the opportunity to purchase Special Common Stock of Genentech
on a quarterly basis. The Board recommends the 1999 Amendment to the Company's
stockholders for adoption.
 
     The affirmative vote of the holders of a majority of the Special Common
Stock and Common Stock represented at the Annual Meeting, voting together as a
single class, is required for the approval of this proposal, provided that a
quorum is present.
 
                    THE BOARD OF DIRECTORS RECOMMENDS A VOTE
                             IN FAVOR OF PROPOSAL 2
 
     The material terms of the 1991 Employee Stock Plan are outlined below.
 
GENERAL DESCRIPTION OF THE 1991 PLAN
 
     The 1991 Plan is intended to qualify under Section 423 of the Internal
Revenue Code of 1986, as amended (the "Code"), as an employee stock purchase
plan. On February 16, 1999, the closing price of Special Common Stock was
$80.375 per share. Rights granted under the 1991 Plan run for a maximum of 27
months.
 
     All full-time employees of Genentech are eligible to participate in the
1991 Plan, except for any employee who owns five percent or more of the total
combined voting power of all classes of stock of Genentech on the date of grant
of a right to purchase shares under the 1991 Plan ("Right"). As of February 16,
1999, there were approximately 3,438 employees of Genentech eligible to
participate in the 1991 Plan. Participation by officers in the 1991 Plan is on
the same basis as that of any other employee. No employee may be granted a Right
that permits such employee to purchase shares under the 1991 Plan at a rate that
exceeds $25,000 of fair market value of such shares (determined on the date of
grant of the Right) for each calendar year in which such Right is outstanding.
Rights are not assignable or transferable by a participating employee.
 
     Under the 1991 Plan, no Right granted to any participating employee may
cover more than 12,000 shares and the maximum number of shares that may be
purchased by all participating employees in any calendar quarter is 180,000
shares, provided that in any calendar quarter in which Genentech pays a regular
annual bonus, the maximum is 200,000 shares. Prior to the 1999 Amendment, the
total number of shares reserved for issuance under the 1991 Plan was 4,500,000
shares. Under the 1999 Amendment, an aggregate total of 5,300,000 shares of
Special Common Stock would be reserved for issuance under the 1991 Plan.
 
                                        9
   12
 
     The Compensation Committee of the Board of Directors fixes grant dates from
time to time on which the Company will grant Rights to purchase shares of
Special Common Stock under the 1991 Plan at prices not less than 85% of the
lesser of (i) the fair market value of the shares on the date of grant or (ii)
the fair market value of the shares on the date of purchase.
 
     Subject to the limits discussed above, the Compensation Committee
establishes the duration of the Rights grant and the terms for participation
under the 1991 Plan. Rights granted under the 1991 Plan are exercisable on such
specific dates and by such method of payment (regular payroll deductions, lump
sum cash payment or both) as determined by the Compensation Committee.
 
     During 1998, the Named Executive Officers purchased the following number of
shares under the 1991 Plan at the prices shown: Dr. Levinson -- 673 shares at
$49.19 per share; Mr. Young -- 776 shares at $49.19 per share; Mr.
Lavigne -- 109 shares at $49.19 per share; Dr. Desmond-Hellmann -- 218 shares at
$49.19 per share; and Dr. Henner -- 478 shares at $49.19 per share; all
executive officers as a group (26 persons) -- 10,731 shares at $49.19 per share;
and all employees (excluding executive officers) as a group -- 416,232 shares at
$49.19 to $59.08 per share.
 
FEDERAL TAX CONSEQUENCES OF THE 1991 PLAN
 
     The following is intended only as a general summary of the federal income
tax consequences in connection with participation in the 1991 Plan. All tax
matters discussed in this Proxy Statement should be verified with a tax
consultant. No taxable income is recognized by a participant either at the time
a Right is granted under the 1991 Plan or at the time the shares are purchased.
Instead, income tax consequences are generally deferred until a participant
disposes of the shares (e.g., by sale or gift). The federal income tax
consequences of a sale of shares purchased under the 1991 Plan depend on the
length of time the shares are held after the relevant date of grant and date of
exercise, as described below.
 
     If shares purchased under the 1991 Plan are held for more than one year
after the date of purchase and more than two years from the date of grant, the
participant generally will have taxable ordinary income on a sale or gift of the
shares to the extent of the lesser of: (i) 15% of the fair market value of the
stock at the date of grant; or (ii) the actual gain (the amount by which the
market value of the shares on the date of sale or gift exceeds the purchase
price). All additional gain upon the sale of stock is treated as long-term
capital gain. If the shares are sold for less than the purchase price, there is
no ordinary income, and the participant has a long-term capital loss for the
difference between the purchase price and the sale price.
 
     If the stock is sold or gifted within either one year after the date of
purchase or two years after the date of grant (a "disqualifying disposition"),
the participant generally has taxable ordinary income at the time of the sale or
gift to the extent that the fair market value of the stock at the date of
purchase was greater than the purchase price. This amount will be taxable in the
year of sale or disposition even if no gain is realized on the sale. A capital
gain would be realized for shares disposed of to the extent sales proceeds
exceed the fair market value of those shares on the date of purchase. A capital
loss would be realized to the extent the sales price of the shares disposed of
is less than the fair market value of such shares on the date of purchase. The
capital gain or loss would be long-term if the stock was held for more than one
year. Special tax consequences may follow from dispositions other than a sale or
gift.
 
     Ordinary income recognized by a participant upon a disqualifying
disposition constitutes taxable compensation which will be reported to the IRS,
but does not constitute "wages" subject to withholding by Genentech. The
Internal Revenue Service is studying this position and other related issues, and
may require withholding in the future. Genentech receives a deduction for
federal income tax purposes only to the extent that a participant realizes
ordinary income on a disqualifying disposition.
 
AMENDMENT OF THE 1991 PLAN
 
     The Board may amend, modify or terminate the 1991 Plan at any time without
notice, provided that no such amendment, modification or termination may
adversely affect any existing Rights of any participating employee, except for
variations to conform with local laws in the case of foreign branches or
designated
 
                                       10
   13
 
U.S. subsidiaries of the Company. In addition, subject to certain appropriate
adjustments to give effect to relevant changes in Genentech's capital stock, no
amendments to the 1991 Plan can be made without stockholder approval if such
amendment would increase the total number of shares offered under the 1991 Plan
or would render Rights "unqualified" for special tax treatment under the Code.
 
AMENDED PLAN BENEFITS
 
     The Company cannot now determine the number of shares of Special Common
Stock that will be purchased in the future under the 1991 Plan by all current
executive officers as a group or by all employees (excluding current executive
officers) as a group. The following table sets forth information with respect to
the number of shares of Special Common Stock purchased during 1998 under the
1991 Plan:

(1) Under the 1991 Plan, eligible employees of the Company may purchase shares
    at prices equal to 85% of the lesser of (i) the fair market value of the
    shares on the date of grant or (ii) the fair market value of the shares on
    the date of purchase. Non-employee members of the Company's Board of
    Directors are not eligible to participate in the 1991 Plan. The Dollar Value
    represents the fair market value per share of Special Common Stock on the
    date of purchase less the actual purchase price per share paid multiplied by
    the number of shares purchased by each person or group on each of the four
    purchase dates in 1998 under the 1991 Plan.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE
 
     Section 16(a) of the Exchange Act requires the Company's directors,
officers and persons who own more than 10% of any class of the Company's equity
securities (collectively, "Reporting Persons") to file reports of ownership and
changes in ownership of such securities. Reporting Persons are required by
Securities and Exchange Commission regulations to furnish the Company with
copies of all Section 16(a) reports they file. The Company believes that all
Forms 3, 4 and 5 required to be filed by its directors, officers and greater
than 10% shareholders were filed on time during 1998.
 
EXECUTIVE COMPENSATION
 
COMPENSATION OF DIRECTORS
 
     In 1998, each of the directors of Genentech, except Dr. Levinson and Mr.
Munro, were paid an annual retainer of $30,000. Mr. Munro, as Chairman of the
Board of Directors, was paid an annual retainer of $50,000. Dr. Levinson was not
paid for his services as a director. In addition, the directors, with the
exception of Dr. Levinson, received a total of $1,500 for each Board and
committee meeting at which the director was present in person and a total of
$500 for each Board and committee meeting at which the director was present by
telephone. All directors were reimbursed for expenses incurred in connection
with their service on the Board. Drs. Boyer and Potts also serve as consultants
to Genentech and receive compensation for their services. In 1998, Drs. Boyer
and Potts received $24,000 and $25,000, respectively, in consideration for their
consulting services. During 1998, no directors exercised options granted under
any of the Company's stock option plans other than Mr. Murfin, who exercised
options to purchase 4,125 shares for a gain of $233,578.
 
     In 1992, the Company established a Directors' Charitable Award Program (the
"Award Program") to acknowledge the service of directors to the Company and
enhance indirectly the ability of the Company to attract and retain directors of
the highest caliber. All members of the Board on or after May 1, 1992 are
eligible for the Award Program, subject to vesting requirements. The Award
Program is funded by life insurance policies purchased by the Company that
provide for a $1 million death benefit on participating directors. Upon the
death of a participating director, the Company may donate $200,000 per year for
five years
 
                                       13
   16
 
to up to four educational institutions or nonprofit organizations recommended by
the director, provided that any such institution or organization is approved by
the Company in the year of the donation. Individual directors derive no
financial benefit from the Award Program since all available insurance proceeds
and tax deductions accrue solely to the Company.
 
     Under the Automatic Grant Program (the "1996 Grant Program") of the
Company's 1996 Stock Option/Stock Incentive Plan (the "1996 Plan"), each
nonemployee member of the Board who is first appointed or elected to the
position after April 30, 1996, will automatically be granted, on the date of
such member's election to the Board, a nonstatutory option to purchase 20,000
shares of Special Common Stock. In addition, each employee director who is first
elected a member of the Board and who subsequently becomes a nonemployee
director after April 30, 1996 shall automatically be granted, on the date of
such individual's change from employee to nonemployee director, a nonstatutory
option to purchase 20,000 shares of Special Common Stock. Each option granted
under the 1996 Grant Program vests in increments of 5,000 shares on each of the
first, second, third and fourth anniversaries of the grant date and remains
exercisable until the expiration or earlier termination of the option term. Such
options have a term of ten years from the grant date. All options granted under
the 1996 Grant Program have an exercise price equal to 100% of the closing
selling price per share of the Company's Special Common Stock on the trading day
prior to the date of grant as reported in the Wall Street Journal. On February
12, 1998, Dr. Knowles was granted a nonstatutory option to purchase 20,000
shares of Special Common Stock at an exercise price of $67.0625 per share under
the 1996 Grant Program.

(1) The options were granted pursuant to the 1996 Plan and are nonstatutory
    options. The options become vested and exercisable as follows: 25% of the
    total option shares vest on the first anniversary of the grant date, with
    the remaining 75% vesting in equal monthly increments thereafter over the
    next three years. In addition, the options fully vest upon the event of a
    Corporate Transaction, as defined in the 1996 Plan, unless the acquiring
    company assumes the options, substitutes similar options or replaces the
    options with a comparable cash incentive program. The options also fully
    vest upon a Change in Control, as defined in the 1996 Plan. Upon an exercise
    of the Call Rights by Roche, the unvested options would be cancelled and the
    Company's Deferred Compensation Plan (the "DCP") would become effective. The
    DCP would replace the cancelled options with an account with a starting
    balance representing the approximate cash value of the cancelled options.
    The DCP account would vest much like the options would have vested,
    following the same vesting schedule.

    Company, including the Named Executive Officers, under all of the Company's
    stock option plans in 1998.
 
(3) The exercise price per share of options granted represented the fair market
    value of the underlying shares of Special Common Stock as based on the
    closing selling price per share of the Company's Special Common Stock on the
    trading day prior to the date of grant.
 
(4) The options granted have a term of ten years subject to earlier termination
    upon the occurrence of certain events related to termination of employment.
 
(5) Present value was determined under the Black-Scholes option pricing model
    based on the following weighted average assumptions: volatility of 11.783,
    representing the annual variance in the daily percentage change in the price
    of the Company's Special Common Stock over a one-year period prior to the
    date of grant; a risk-free interest rate of 5.41%, representing the average
    seven-year treasury bill; an average expected term of 7 years; a stock price
    at the grant date of $68.375 and a stock price upon exercise of $68.375.
    This valuation model was not adjusted for the vesting restrictions or the
    risk of forfeiture of the options. Under SFAS 123, forfeitures may be
    estimated or assumed to be zero; in this model, the forfeiture rate was
    assumed to be zero. The Company's use of this model in accordance with rules
    adopted by the Securities and Exchange Commission does not constitute an
    endorsement of the model nor an acknowledgment that such model can
    accurately determine the value of options. The valuation calculations do not
    necessarily represent the fair market value of individual options, and are
    not intended to forecast possible future appreciation, if any, of the price
    of the Special Common Stock. The ultimate realizable value of an option will
    depend on the market value of the Company's Special Common Stock on the date
    of exercise as compared to the exercise price of the option.

LOANS AND OTHER COMPENSATION
 
     In 1994, Genentech lent $250,000 to Ms. Kimberly Popovits, Vice President,
Sales, for the purchase of a home in connection with her relocation to the San
Francisco Bay Area. The loan is imputed to bear interest at the rate of 8.20%.
$150,000 of the loan is repayable in full on the earlier of five years from the
date the loan was made or the date of Ms. Popovits' termination of employment
with Genentech. $100,000 of the loan will be forgiven in five equal amounts on
the anniversary dates of the loan, provided Ms. Popovits is employed by
Genentech on such anniversary dates. The largest amount outstanding under the
loan during 1998 was $190,000, and $170,000 of the principal balance of the loan
is outstanding as of the date of this Proxy Statement. The imputed interest on
the loan is compensatory to Ms. Popovits and amounted to $15,763 in 1998.
 
     In 1992, Genentech lent $282,287 to Dr. John Curd, Vice President, Clinical
Development, for the purchase of a home in connection with his relocation to the
San Francisco Bay Area, and in 1994, Genentech lent $150,000 to Dr. Curd in
connection with a refinancing of the same residence. The 1994 and 1992 loans are
imputed to bear interest at the rate of 6.62%. $45,000 of the 1992 loan was
forgiven in two equal installments on the third and fourth anniversary dates of
the loan, leaving an aggregate balance of $387,287 for the two loans at that
time. In April 1996, Genentech amended the terms of the 1992 and 1994 loans to
forgive all amounts due under these loans in four equal installments on March 15
of 1997, 1998, 1999 and 2000, provided Dr. Curd is employed by Genentech on such
dates. In 1998, $96,822 of these loans was forgiven. The largest aggregate
amount outstanding under these loans during 1998 was $290,465, and $193,644 of
the aggregate principal balance of these loans is outstanding as of the date of
this Proxy Statement. The imputed interest on these loans is compensatory to Dr.
Curd and amounted to $16,876 in 1998.
 
     In 1997, Genentech lent $150,000 to Ms. Judy Heyboer, Senior Vice
President, Human Resources, for the purchase of a home in connection with her
relocation to San Mateo County. The loan is imputed to bear interest at the rate
of 6.74%. $75,000 of this loan is due and payable on the earlier of the fifth
anniversary of the date of the loan or the date of termination of Ms. Heyboer's
employment with Genentech. The remaining $75,000 will be forgiven in five equal
installments on the anniversary dates of the loan, provided Ms. Heyboer is
employed by Genentech on each of the forgiveness dates. The largest amount
outstanding under this loan during 1998 was $150,000, and the $135,000 of the
principal balance of this loan is outstanding as of the date

Ms. Heyboer and amounted to $10,028 in 1998.
 
     In 1994, Genentech lent $60,000 to Mr. Sean Johnston, Vice President,
Intellectual Property, for the purchase of a home. The loan is imputed to bear
interest at the rate of 6.98% and is due and payable in full on the earlier of
October 15, 1999 or the date of termination of Mr. Johnston's employment with
Genentech. The largest amount outstanding under this loan during 1998 was
$64,261, and $60,000 of this loan is outstanding as of the date of this Proxy
Statement. The imputed interest is compensatory to Mr. Johnston and amounted to
$4,261 in 1998.
 
COMPENSATION COMMITTEE REPORT(1)
 
     The Compensation Committee of the Board of Directors (the "Committee") is
currently composed of four nonemployee directors. The Committee is responsible
for setting and administering the policies that govern annual executive
salaries, bonuses (if any) and stock ownership programs. The Committee annually
evaluates the performance, and determines the compensation, of the Chief
Executive Officer ("CEO") and the other executive officers of Genentech based
upon a mix of the achievement of the corporate goals, individual performance and
comparisons with other pharmaceutical and biotechnology companies. The CEO is
not present during the discussion of his compensation.
 
     The policies of the Committee with respect to executive officers, including
the CEO, are to provide compensation sufficient to attract, motivate and retain
executives of outstanding ability and potential and to establish an appropriate
relationship between executive compensation and the creation of shareholder
value. To meet these goals, the Committee has adopted a mix among the
compensation elements of salary, bonus and stock options, with some bias toward
stock options to emphasize the link between executive incentives and the
creation of shareholder value as measured by the equity markets. In general, the
salaries and stock option awards of executive officers are not determined by the
Company's achievement of specific corporate performance criteria. Instead, the
Committee determines the salaries for executive officers based upon a review of
salary surveys of other pharmaceutical, biotechnology and San Francisco Bay Area
companies performed for the Committee. To provide the Committee with more
information for making compensation comparisons, Genentech surveys a broader
group of pharmaceutical and biotechnology companies than those companies
included in the Standard & Poors Healthcare (Drug) Index shown on Genentech's
Performance Graph. Based upon such surveys, the executive officers' salaries are
targeted at the fiftieth (50th) percentile, and officers' salaries and bonuses
are targeted at the seventy-fifth (75th) percentile, as compared to other
biotechnology companies, while stock options are set in the mid to high range
compared to other pharmaceutical companies. In awarding stock options, the
Committee considers individual performance, overall contribution to Genentech,
officer retention, the number of unvested stock options and the total number of
stock options to be awarded. After considering the criteria relating to awarding
stock options, during 1998 the Committee awarded to 24 of the current executive
officers, including all of the Named Executive Officers, options to purchase an
average of 64,375 shares of Genentech's Callable Putable Common Stock. In
determining where a given officer's total compensation, including the CEO's, is
set within the ranges and in light of the considerations described above, the
Committee subjectively evaluates such factors as the individual's performance
and the success of Genentech as measured by earnings per share, product
development progress, research prospects, and other critical success factors.
 
     Bonuses are provided to executive officers as part of Genentech's
company-wide bonus plan. Payment of bonuses is expressly linked to the
attainment of specified corporate goals that the Committee sets at each year's
December meeting for the next year. Among other things, these goals determine
whether a bonus will be paid to all eligible employees and the amount of funding
available for the bonus pool. For the bonus for services rendered in 1998, the
corporate performance goals, in order of importance, related to: (i) business
and financial performance,

including but not limited to increasing earnings per share, revenues and net
income percentage and forming strategic alliances by in-licensing products and
establishing relationships with other companies; (ii) accelerating and expanding
product development by filing Investigational New Drug Applications, initiating
or completing specified clinical trials investigating the use of new products,
selecting new products for development and filing New Drug Applications or
Product License Applications for new indications of marketed products; and (iii)
enhancing employee development. In setting these goals, the Committee is
cognizant of the long development cycle for human pharmaceuticals. The corporate
performance goals for bonuses selected by the Committee seek to balance the
desire for immediate earnings and the longer term goal of enhancing shareholder
value by bringing to market many of the potential therapies in Genentech's
research and development pipeline. In February 1999, the Committee reviewed the
corporate performance goals for bonuses and determined that approximately $18.0
million of the $20.2 million of corporate bonus targets were achieved. The
Committee allocated a bonus to the current CEO based on the achievement of the
requisite corporate goals, as discussed above, and based on the Committee's view
that the CEO's performance in achieving those goals had been excellent. The
Committee set a range of 20% to 40% of salary for bonuses for executive officers
other than the members of the Company's Executive Committee (Drs. Levinson,
Desmond-Hellman and Henner, Ms. Judy Heyboer and Messrs. Stephen G. Juelsgaard,
Lavigne and Young) and a range of 35% to 100% of salary for bonuses for members
of the Company's Executive Committee other than the CEO, in light of the
decision (discussed below) to forego base salary increases in 1998. Within the
applicable range, the Committee set the bonus for each executive officer based
on the Committee's subjective evaluation of the individual's performance and the
recommendation of the CEO.
 
     The Committee uses the same procedures described above for the other
executive officers in setting the annual salary, bonus and stock option awards
for the CEO. The CEO's salary is determined based on comparisons with
pharmaceutical and biotechnology companies as described above. In awarding stock
options, the Committee considers the CEO's performance, overall contribution to
Genentech, retention, the number of unvested stock options held and the total
number of options to be awarded. The CEO's bonus is dependent on Genentech
achieving the performance goals outlined above and the Committee's subjective
evaluation of the CEO's performance. As described above, in determining where
the CEO's total compensation is set within the ranges and in light of the
considerations described above, the Committee subjectively evaluates such
factors as the individual's performance and the success of Genentech as measured
by the factors outlined above. In 1997, the Committee elected, at the request of
Dr. Levinson and the Company's Executive Committee, to not increase the base
salaries in 1998 for Dr. Levinson and Executive Committee members. Instead,
these select executive officers participate in an expanded bonus program
approved by the Committee that ties the amount of bonus to earnings performance.
Compared to other companies surveyed by Genentech, the current CEO's salary,
bonus and stock options are competitive.
 
     Section 162(m) of the Code limits the federal income tax deductibility of
compensation paid to Genentech's CEO and to each of the Named Executive
Officers. Under Section 162(m), Genentech generally may deduct compensation paid
to such an officer only to the extent that it does not exceed $1 million during
any calendar year or is "performance-based" as defined in Section 162(m).
Genentech expects that the deductibility limit of Section 162(m) currently will
have an insignificant effect on Genentech. Current cash compensation paid to
each of Genentech's executives, with one exception, is less than $1 million per
year and is thus generally fully deductible to the Company. In addition, since
January 1, 1997, all stock options granted to the Company's executive officers
(under Genentech's 1994 Stock Option Plan and 1996 Stock Option/ Stock Incentive
Plan) have been qualified as performance-based compensation under Section
162(m). Thus, Genentech will continue to receive a federal income tax deduction
in connection with the exercise of such stock options. Finally, all options
granted prior to January 1, 1997 under Genentech's various stock option plans,
with one exception, are exempt from the deductibility limitation of Section
162(m) pursuant to various transition rules contained in the regulations under
Section 162(m).

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
     During 1998, Genentech's Compensation Committee consisted of Drs. Boyer and
Humer, Ms. Levinson and Mr. Munro. Dr. Humer joined The Roche Group in 1995 as
the Head of its Pharmaceuticals Division and is currently Chief Executive
Officer of The Roche Group. He is also a member of the Board of Directors and
Chairman of the Executive Committee of The Roche Group. Pursuant to the terms of
the Amended Governance Agreement, Dr. Humer is serving on Genentech's
Compensation Committee as a designee of Roche. See "Certain Relationships and
Related Transactions" below for a description of Genentech's relationship with
Roche.
 
CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
     In January 1980, Genentech and Hoffmann-La Roche Inc. ("Hoffmann-La Roche")
entered into an agreement regarding the development and commercialization of
human leukocyte ("alpha") and fibroblast ("beta") interferons (the "Interferon
License Agreement"). Hoffmann-La Roche is a New Jersey corporation and a
subsidiary of Roche, and as such is affiliated with Genentech. Pursuant to this
agreement, as amended from time to time, Genentech granted Hoffmann-La Roche a
sole and exclusive, worldwide license to use and sell (and, under certain
circumstances, manufacture) alpha and beta interferons using organisms and
knowhow developed by Genentech and under patent rights belonging to Genentech,
for a period of 20 years. Pursuant to this agreement, Genentech is entitled to
royalties on sales of interferons by Hoffmann-La Roche for 10 years after
commercial introduction, unless the period of exclusivity is extended for an
additional 5-year, royalty-bearing period. These royalties totaled $11.6 million
in 1998.
 
     Effective April 1, 1998, Genentech transferred back to Roche the
promotional rights to Roferon(R)-A. In consideration, Genentech received $5
million plus royalties for sales of alpha interferon under the Interferon
License Agreement described above.
 
     In May 1991, Genentech entered into an agreement with Hoffmann-La Roche in
settlement of all disputes, including all issues in litigation between the
parties, relating to the Li patent on human growth hormone and methods for its
preparation. Under the settlement agreement, Genentech received a nonexclusive
license under the patent and will make payments and/or grant credits, against
future royalties under the Interferon License Agreement described above, to
Hoffmann-La Roche totaling $4 million over a ten-year period. In addition,
Hoffman-La Roche received a paid-up nonexclusive license under certain Genentech
patents for specific product applications.
 
     In January 1992, Genentech entered into an agreement with HLR relating to
the development and supply of a recombinant tumor necrosis factor ("TNF")
receptor-fusion protein being evaluated for use in septic shock, rheumatoid
arthritis and multiple sclerosis. Pursuant to this agreement, Genentech is
responsible for developing and scaling up a recombinant production process for
TNF receptor-fusion protein and for supplying preclinical and clinical
requirements of such material and, eventually, commercial requirements. HLR
reimburses Genentech for certain costs of developing and scaling its
manufacturing capability and will purchase manufactured TNF receptor-fusion
protein from Genentech; for 1998, such costs totaled approximately $2.5 million.
 
     Genentech and Roche have also entered into a Small Molecule Screening
Agreement for the screening of Roche's chemical library using certain mutually
agreed Genentech assays to find lead molecules for development into small
molecule therapeutics. Roche has the responsibility for supplying the chemical
library to be screened. Genentech has the responsibility for supplying the
assays and for undertaking the initial screening. If the screening results in
the identification of a molecule of interest to one of the parties, that party
shall advise the other party of its interest. The second party can then elect to
proceed with the interested party and jointly develop the molecule or it can
choose to let the interested party develop the molecule on its own. If a
molecule is jointly developed, the parties are to share equally the cost of
joint development and to agree to a plan proportioning research and development
responsibilities between them based on their capability. If a product is jointly
developed, both Genentech and Roche have the right to make, use and sell that
product and will negotiate an allocation of the major marketing territories
between them as well as appropriate royalties payable by each to the other for
sales of that product in that party's marketing territory. As a general
principle,
                                       20
   23
 
the markets for each product are to be allocated on an equal basis, but
Genentech is to have at least 50% of the marketing rights in North America and
Roche is to have at least 50% of the marketing rights in Europe, subject to
certain exceptions. After allocation of marketing rights, each party is to pay
the other a royalty on sales in that party's marketing territory with the
royalty to be determined by negotiation. As a general principle, the percentage
royalty payable on sales by either party to the other should have equivalent
royalty rates. If a product is unilaterally developed, the party unilaterally
developing that product has the sole right to make, use and sell that product
throughout the world and will pay the other party a royalty of 5% of sales.
 
     In 1994, Genentech entered into four R&D collaboration agreements with HLR
and Hoffmann-La Roche, each an affiliate of Genentech. The four collaborations
are in the areas of oral IIb/IIIa antagonists, oral IL-8 antagonists, oral
LFA/ICAM antagonists, and ras farnesyltransferase inhibitors. The collaboration
pursuant to the IL-8 agreement has been terminated.
 
     The oral IIb/IIIa antagonist agreement was further amended in principal in
the second quarter of 1997 and in the second and fourth quarters of 1998.
Pursuant to those amendments, HLR assumed development of the oral IIb/IIIa
antagonist globally on its own. Genentech may subsequently opt-in and join
development at any time up to 30 days after the NDA approval for the first
indication. If Genentech chooses to opt-in, it will make a payment to HLR of $25
million and reimburse HLR for 50% of the U.S. and European IIb/IIIa development
costs incurred from May 1, 1997 to the opt-in date. HLR and Genentech will
co-promote IIb/IIIa in the U.S. with a 60/40, Genentech/HLR, profit-sharing if
the NDA approval for the first indication is for acute therapy or a 50/50
profit-sharing if the NDA approval for the first indication is for chronic
therapy. If Genentech does not opt-in, it will receive from HLR a 6% royalty on
worldwide sales of the oral IIb/IIIa antagonist.
 
     The LFA/ICAM agreement is in the process of being amended and expanded to
include VLA-4/VCAM antagonists and anticoagulants. It is expected that, as
amended, the agreement would provide that Genentech will have the sole right to
sell LFA-1/ICAM antagonists and anticoagulants in the United States and retain
all associated profits, and Roche will have the sole right to sell those
products outside the U.S. and retain all associated profits, and that with
respect to VLA-4/VCAM, Roche will have the sole right to sell those products
throughout the world, will pay Genentech a royalty of 5% on such sales and will
retain all associated profits. It is expected that Genentech and Roche will
share equally the development costs associated with the development of
LFA-1/ICAM antagonists and anticoagulants in the U.S. and Europe, except where
those costs are allocable to or involve countries outside the U.S. and Europe.
It is expected that Roche will have the sole responsibility for all the
development costs associated with the development of VLA-4/VCAM antagonists.
 
     In addition to the foregoing agreements, Genentech has developed a
mammalian cell line for HLR to produce a molecule that HLR has developed. HLR
will provide Genentech future services of an equivalent value in exchange for
Genentech's development efforts.
 
     On July 6, 1998, the Company entered into an agreement with HLR to provide
HLR exclusive marketing rights outside of the U.S. for
Herceptin(R)(Trastuzumab). Under the agreement, HLR paid a $40 million up-front
fee and has agreed to pay cash milestones tied to product development
activities, to contribute equally with the Company up to a maximum of $40
million on global development costs and to make royalty payments on product
sales. Genentech received no further amounts under the agreement in 1998.
 
     In July 1997, Genentech entered into a Group Purchasing Agreement with VHA
pertaining to the purchase by its member hospitals of Activase(R)(Alteplase,
recombinant) tissue plasminogen activator for the treatment of heart attack,
acute ischemic stroke and acute massive pulmonary embolism by its member
hospitals. VHA has created a joint venture, Novation, with University Health
Systems Consortium, and has assigned the agreement with Genentech to Novation.
Mr. Smith, a member of the Board of Directors of Genentech, is President and
Chief Executive Officer of VHA. Pursuant to the Group Purchasing Agreement,
Genentech pays Novation an administrative fee, based on a percentage of the
purchases of Activase(R) by Novation member hospitals. The percentage
administrative fee earned by Novation is dependent upon the volume of
Activase(R) purchased by member hospitals compared to the volume purchased in
the same period
 
                                       21
   24
 
for the previous year. Amounts paid to Novation under the Group Purchasing
Agreement totaled $812,313 in 1998.
 
     The Company has contracted with Jacobs Engineering Group, Inc. ("Jacobs")
to provide design and engineering services for various projects of the Company.
Ms. Levinson, a member of the Board of Directors of Genentech, is a member of
the Board of Directors of Jacobs. Amounts paid by Genentech to Jacobs totaled
$5.6 million in 1998.
 
     In October 1996, Genentech entered into a Collaborative Research Agreement
with The General Hospital Corporation to conduct collaborative research with Dr.
Mark Fishman of Massachusetts General Hospital ("MGH") pertaining to the
discovery and identification of new genes. Dr. Fishman is the son-in-law of Dr.
John T. Potts, Jr., a member of the Board of Directors of Genentech. Pursuant to
the agreement, Genentech provided funding to support such collaborative research
in Dr. Fishman's laboratories in the amount of $1.2 million per year over the
twenty-six month term of the agreement. Genentech received an option to a
royalty-bearing license to inventions made in the course of the collaboration.
As of January 1, 1999, the agreement was extended for a two-year period, and
Genentech agreed to provide $1.2 million in funding per year to support

        PROPOSAL 3 -- RATIFICATION OF SELECTION OF INDEPENDENT AUDITORS
 
     The Board of Directors has selected Ernst & Young LLP as Genentech's
independent auditors for the year ending December 31, 1999, and has further
directed that management submit the selection of independent auditors for
ratification by the stockholders at the Annual Meeting. Ernst & Young LLP has
audited Genentech's financial statements since its inception in 1976.
Representatives of Ernst & Young LLP are expected to be present at the Annual
Meeting, will have an opportunity to make a statement if they desire to do so
and will be available to respond to appropriate questions.
 
     Stockholder ratification of the selection of Ernst & Young LLP as
Genentech's independent auditors is not required by the Bylaws or otherwise. The
Board of Directors has elected to seek such ratification as a matter of good
corporate practice. Should the stockholders fail to ratify the selection of
Ernst & Young LLP as independent auditors, the Board of Directors will consider
whether to retain that firm for the year ending December 31, 1999.

     The affirmative vote of the holders of a majority of the Special Common
Stock and Common Stock represented at the Annual Meeting, voting together as a
single class, is required for approval of this proposal, provided that a quorum
is present.
 
                    THE BOARD OF DIRECTORS RECOMMENDS A VOTE
                         IN FAVOR OF SUCH RATIFICATION
 
                                 OTHER MATTERS
 
     The Board of Directors knows of no other business to be presented at the
Annual Meeting, but if other matters do properly come before the Annual Meeting,
it is intended that the persons named on the Proxy Card will vote on such
matters in accordance with their best judgment.
