                          (ZERO COUPON--SUBORDINATED)
                               ------------------

    The issue price  of each  Liquid Yield  Option-TM- Note  ("LYON"-TM-) to  be
issued  by ALZA Corporation, a Delaware corporation ("ALZA"), will be  $
(    % of principal amount  at maturity) (the "Issue Price"), and there will  be
no  periodic payments of interest. The  LYONs will mature on June    , 2014. The
Issue Price of  each LYON represents  a yield to  maturity of       % per  annum
(computed on a semi-annual bond equivalent basis) calculated from June   , 1994.
The LYONs will be subordinated to all existing and future Senior Indebtedness of
ALZA,  the principal  amount of  which as  of April  30, 1994  was $1.7 million,
excluding ALZA's  $249.3  million  principal amount  of  outstanding  commercial
paper, which will be retired with a portion of the proceeds from the sale of the
LYONs.  See  "Capitalization"  and  "Description of  LYONs  --  Subordination of
LYONs."

    Each LYON will be convertible at the option of the Holder at any time on  or
prior  to maturity, unless  previously redeemed or  otherwise purchased by ALZA.
Upon conversion, ALZA  may elect  to deliver Common  Stock, par  value $.01  per
share  (the "Common Stock"), of ALZA at a conversion rate of          shares per
LYON (the "Conversion Rate") or cash equal to the market value of the shares  of
Common  Stock into which the LYONs are convertible. The Conversion Rate will not
be adjusted  for  accrued  Original  Issue Discount,  but  will  be  subject  to
adjustment  upon the  occurrence of certain  events affecting  the Common Stock.
Upon conversion,  the Holder  will  not receive  any cash  payment  representing
accrued  Original Issue Discount;  such accrued Original  Issue Discount will be
deemed paid by the Common Stock or cash received on conversion. See "Description
of LYONs -- Conversion Rights." On May 13, 1994, the last reported sale price of
the Common Stock on the New York Stock Exchange was $23 1/8 per share.

    LYONs will be purchased by ALZA, at the option of the Holder, as of June   ,
1999, June   , 2004 and June    , 2009 (each, a "Purchase Date") for a  Purchase
Price  per LYON of $         , $         and $         (Issue Price plus accrued
Original Issue Discount  to such  Purchase Date),  respectively, representing  a
yield  per annum to the Holder on each such Purchase Date of    % (computed on a
semi-annual bond equivalent basis). Subject to certain conditions, ALZA, at  its
option,  may elect to pay the Purchase  Price as of any particular Purchase Date
in cash  or  shares  of  Common  Stock,  or  in  any  combination  thereof.  See
"Description  of LYONs  -- Purchase of  LYONs at  the Option of  the Holder." In
addition, as of 35 business days after  the occurrence of any Change in  Control
of  ALZA occurring on or prior to June   , 1999, each LYON will be purchased for
cash by ALZA,  at the option  of the Holder,  for a Change  in Control  Purchase
Price  equal to the Issue Price plus accrued Original Issue Discount to the date
set for such purchase.  See "Description of LYONs  -- Change in Control  Permits
Purchase of LYONs at the Option of the Holder."

    The LYONs will not be redeemable by ALZA prior to June   , 1999. Thereafter,
the LYONs are redeemable for cash at any time at the option of ALZA, in whole or
in  part, at Redemption  Prices equal to  the Issue Price  plus accrued Original
Issue Discount  to  the  date  of  redemption.  See  "Description  of  LYONs  --
Redemption of LYONs at the Option of ALZA."

    For  a discussion of certain United States federal income tax considerations
for  Holders  of  LYONs,   see  "Certain  United   States  Federal  Income   Tax
Considerations."

    Application has been made to list the LYONs on the New York Stock Exchange.

                               PROSPECTUS SUMMARY

    THE FOLLOWING SUMMARY IS QUALIFIED BY THE DETAILED INFORMATION AND FINANCIAL
STATEMENTS  INCLUDED ELSEWHERE OR INCORPORATED  BY REFERENCE IN THIS PROSPECTUS.
UNLESS OTHERWISE INDICATED, THE INFORMATION IN THIS PROSPECTUS ASSUMES THAT  THE
UNDERWRITER'S OVER-ALLOTMENT OPTION IS NOT EXERCISED.

                                      ALZA

    ALZA  is the recognized leader in the development of pharmaceutical products
based on controlled drug delivery technologies. Since the company's founding  in
1968,  ALZA's research and development efforts have resulted in a broad range of
proprietary therapeutic systems designed to  improve the medical value and  cost
effectiveness  of drug compounds by  improving efficacy, minimizing side effects
and/or providing greater patient  compliance. Among the ALZA-developed  products
commercialized  to  date  by  client  companies  are  Procardia  XL-R-,  for the
treatment  of   both  angina   and  hypertension,   Volmax-R-  (albuterol),   an
anti-asthmatic product, and Efidac/24-R-, an over-the-counter nasal decongestant
product,   all   utilizing  ALZA's   OROS-R-   oral  therapeutic   systems;  and
Transderm-Nitro-R- for the prevention and  treatment of angina, Nicoderm-R-,  an
aid  in smoking cessation,  and Duragesic-R- for the  management of chronic pain
(such as cancer pain), utilizing  various transdermal therapeutic systems.  More
than  60 additional products  utilizing ALZA therapeutic  systems are in various
stages of development  or clinical evaluation,  a number of  which are  awaiting
marketing  clearance in the United States  and/or other countries. ALZA recently
announced United States Food  and Drug Administration  ("FDA") clearance of  two
products  --  Glucotrol  XL-R- and  Actisite-R-  (tetracycline  HCl) periodontal
fiber. Glucotrol XL-R-, developed  jointly with Pfizer, Inc.,  is a product  for
the  treatment  of  diabetes taken  orally  once a  day.  Actisite-R-, developed
jointly  with  On-Site  Therapeutics,  Inc.,  is  the  first  sustained-release,
site-specific  drug therapy cleared  for marketing in the  United States for the
treatment of patients with adult periodontitis.

    Most of ALZA's product development activities have been undertaken  pursuant
to joint development and commercialization agreements, including agreements with
many  of the world's largest pharmaceutical companies. These agreements normally
provide for the pharmaceutical company client to reimburse ALZA for ALZA's costs
incurred in product  development and  clinical evaluation.  The client  receives
marketing  rights to the products and  ALZA receives royalties on product sales.
In some cases,  ALZA has rights  to co-promote the  products developed. In  many
cases,  ALZA manufactures all or  a portion of the  client's requirements of the
product. ALZA's  clients  often  take  responsibility  for  obtaining  necessary
regulatory   approvals  and  make  all  marketing  and  other  commercialization
decisions regarding the products. Therefore,  most of the variables that  affect
ALZA's  royalties and  fees are  not within ALZA's  control. For  the year ended
December  31,  1993,  royalties  from  sales  of  Procardia  XL  accounted   for
approximately 60% of ALZA's royalties and fees.

    As  part  of ALZA's  Target 2000  strategic plan,  ALZA intends  to increase
significantly the development, manufacturing and  marketing of its own  products
in  addition to  continuing its  client-based business.  In furtherance  of this
goal, ALZA  formed Therapeutic  Discovery  Corporation ("TDC")  and  distributed
"units,"  consisting of TDC shares  and ALZA warrants, as  a special dividend to
ALZA stockholders in  June 1993. TDC  was formed to  develop and  commercialize,
most  likely  through  licensing  to ALZA,  products  incorporating  ALZA's drug
delivery systems with various drug  compounds. ALZA contributed $250 million  in
cash  to TDC  and will  develop products  on behalf  of TDC  under a development
contract. ALZA has an option to license each product developed by TDC, and  also
has  an option to purchase all of the  TDC shares. The formation of TDC, and the
development of products with TDC, are intended to result in a potential pipeline

 (1) Includes  approximately $5.0 million of  one-time investment gains realized
     on long-term investments liquidated in connection with ALZA's  contribution
     to TDC. See "Prospectus Summary."
 (2) Includes  pre-tax charges and allowances of  $28.1 million ($0.23 per share
     on an after-tax basis) related primarily to manufacturing activities.
 (3) In 1991 ALZA incurred a one-time  charge of $101.3 million relating to  the
     purchase  of in-process  technology in  connection with  the acquisition of
     Bio-Electro Systems, Inc., a company acquired by ALZA in early 1992.
 (4) In February 1992, the Financial Accounting Standards Board issued Statement
     of Financial Accounting  Standards No. 109,  "Accounting for Income  Taxes"
     ("SFAS  109"). ALZA  adopted the  provisions of  SFAS 109  in its financial
     statements for the quarter ended March  31, 1993, increasing net income  by
     $6.6  million  ($0.08 per  share).  As permitted  by  SFAS 109,  prior year
     financial statements  have  not been  restated  to reflect  the  change  in
     accounting method.
 (5) On  November 15,  1993 ALZA  redeemed all  of its  outstanding 7  1/2% zero
     coupon  convertible  subordinated  debentures.  In  connection  with   this
     redemption,   ALZA  incurred   a  $3.8   million  (net   of  income  taxes)
     extraordinary refinancing  charge.  The  7  1/2%  zero  coupon  convertible
     subordinated  debentures  were  replaced with  commercial  paper  which was
     classified as short term debt, thereby reducing working capital.
 (6) Per share data  for 1989 and  1990 have been  restated to give  retroactive
     effect to a two-for-one stock split effective November 1991.
 (7) In  May 1993, the Financial Accounting  Standards Board issued Statement of
     Financial Accounting Standards No. 115, "Accounting for Certain Investments
     in Debt and Equity Securities" ("SFAS 115"). ALZA adopted the provisions of
     the new standard for  investments held as of  or acquired after January  1,
     1994.  In accordance with SFAS 115,  prior period financial statements have
     not been restated to reflect the change in accounting principle. Under SFAS
     115, all available-for-sale  securities were classified  as current  assets
     and  a $2.3 million  valuation allowance was established  at March 31, 1994
     for the difference between their cost and fair market value.
 (8) Stockholders' equity decreased from December 31, 1992 to December 31,  1993
     and  from  March  31, 1993  to  March 31,  1994  due primarily  to  the TDC
     distribution. See "Prospectus Summary."
 (9) The ratios of earnings to fixed charges were calculated by dividing the sum
     of (i)  income  (loss) before  income  taxes, extraordinary  item  and  the
     cumulative  effect of the accounting change and (ii) fixed charges (reduced
     by capitalized interest costs), by fixed charges. Fixed charges consist  of
     interest (expensed and capitalized), amortization of debt issue expense and
     the estimated interest portion of rent expense.
(10) Earnings  for the year  ended December 31, 1991  were insufficient to cover
     fixed charges by approximately $43 million.
(11) The pro forma ratio of  earnings to fixed charges  assumes the 7 1/2%  zero
     coupon   convertible  subordinated  debentures  and  the  commercial  paper
     outstanding  during  the  periods  presented  had  been  refinanced  on   a
     retroactive basis by the new LYONs.

                           INVESTMENT CONSIDERATIONS

    RELATIONSHIPS  WITH CLIENT COMPANIES.   ALZA's net  income currently results
primarily from royalties and fees paid  by client companies. Royalties and  fees
are   derived  from  sales  by  the   clients  of  products  incorporating  ALZA
technologies, and therefore vary from quarter to quarter as a result of changing
levels of product  sales by client  companies. Because ALZA's  clients make  all
marketing  and other commercialization  decisions with respect  to such products
(including,  in  many  cases,  taking  responsibility  for  obtaining  necessary
regulatory  approvals), most of  the variables that  affect ALZA's royalties and
fees are not directly within ALZA's  control. In addition, ALZA's royalties  and
fees  could be adversely affected  if the pressures for  cost containment in the
United States health  care system  were to result  in lower  selling prices  for
royalty-bearing products. During the quarter ended March 31, 1994, Procardia XL,
marketed  by Pfizer, Inc.,  accounted for approximately  60% of ALZA's royalties
and fees.

    RECENT   AND   PLANNED    EXPANSION   OF    MARKETING   AND    MANUFACTURING
ACTIVITIES.  ALZA recently began marketing the Testoderm transdermal therapeutic
system,  and intends to expand its sales and marketing activities in the future,
under co-promotion  arrangements, under  its arrangements  with TDC,  and  under
other  arrangements with third  parties (which could  include the acquisition or
license of  products and/or  technologies). While  the activities  with TDC  and
other  third parties are intended  to result in a  valuable pipeline of products
for marketing by ALZA,  there can be  no assurance that this  will be the  case.
ALZA  also has expanded and is continuing to expand its manufacturing facilities
in anticipation of future manufacturing  needs. Utilization of these  facilities
in  any  quarter  depends  on many  factors,  including  client  orders, product
approvals, and product launches and sales,  many of which are outside of  ALZA's
control.  There can  be no assurance  that ALZA's expanded  sales, marketing and
manufacturing activities will be successful.

    VOLATILITY OF SECURITIES PRICES.  The market prices of ALZA's securities are
subject to  significant  fluctuations in  response  to variations  in  quarterly
operating  results,  announcements of  new commercial  products  by ALZA  or its
competitors, developments or disputes  concerning patent or proprietary  rights,
regulatory  developments in both the United States and foreign countries, health
care reform  and  regulation,  and  economic  and  other  external  factors.  In
addition,  the pharmaceutical  sector of  the stock  market has  in recent years
experienced significant  price  fluctuations.  Such  fluctuations,  as  well  as
economic  conditions generally, may adversely affect  the market price of ALZA's
securities.

                                USE OF PROCEEDS

    The aggregate net proceeds to ALZA from the sale of the LYONs offered hereby
are estimated to be approximately $    million (or approximately $    million if
the Underwriter's over-allotment option is exercised  in full). ALZA will use  a
portion  of the  net proceeds  to retire at  maturity all  of ALZA's outstanding
commercial paper, which had an aggregate  principal amount of $249.3 million  as
of April 30, 1994, and had maturities of less than 120 days and bore interest as
of  such date at rates  ranging from 3.65% to 4.22%  per annum. The remainder of
the net proceeds  will be  used for  general corporate  purposes, which  include
working  capital, acquisition of additional  facilities and equipment, expansion
of  ALZA's   pharmaceutical  business   (including  its   sales  and   marketing
activities),  possible expenditures under joint  ventures, partnerships or other
similar agreements,  and  the  possible  acquisition  of  assets,  technologies,
products and businesses to expand ALZA's existing operations. Pending such uses,
ALZA will invest the net proceeds of the offering in marketable securities.

                PRICE RANGE OF COMMON STOCK AND DIVIDEND POLICY

    ALZA's  Common Stock  is traded  on the  New York  Stock Exchange  under the
symbol AZA. Prior to June 1, 1992,  the Common Stock was traded on the  American
Stock  Exchange under the same  symbol. The following table  sets forth the high
and low per share sales price for the Common Stock as reported on the  composite
tape  for the applicable exchange for  the quarters indicated. The last reported
sale price for the Common Stock on the  New York Stock Exchange on May 13,  1994
was  $23  1/8.  These  prices  do not  include  retail  mark-ups,  mark-downs or
commissions.

                              DESCRIPTION OF LYONS

    The LYONs are to be issued under an indenture to be dated as of June 1, 1994
(the "Indenture") between ALZA  and The Chase Manhattan  Bank, N.A., as  trustee
(the  "Trustee"). A copy of the form of  Indenture is filed as an exhibit to the
Registration Statement  of  which  this  Prospectus is  a  part.  The  following
summaries of certain provisions of the LYONs and the Indenture do not purport to
be complete and are subject to, and are qualified in their entirety by reference
to, all the provisions of the LYONs and the Indenture, including the definitions
therein  of certain  terms which are  not otherwise defined  in this Prospectus.
Wherever particular provisions or defined terms of the Indenture (or of the Form
of LYON which is  a part thereof)  are referred to,  such provisions or  defined
terms are incorporated herein by reference. References herein are to sections in
the Indenture and paragraphs in the Form of LYON.

GENERAL

    The  LYONs will  be unsecured  obligations of  ALZA limited  to $825,000,000
aggregate principal amount at maturity ($948,750,000 aggregate principal  amount
at maturity if the Underwriter's over-allotment option is exercised in full) and
will  mature on June   , 2014. The  principal amount at maturity of each LYON is
$1,000 and will be payable  at the office of  the Paying Agent, which  initially
will  be the Trustee, in The  City of New York, and  payment will be made at its
office in New York, or any other office of the Paying Agent maintained for  such
purpose. (Sections 2.2, 2.3 and 4.5 and Form of LYON, paragraph 3.)

    The  LYONs are being offered at  a substantial discount from their principal
amount at  maturity.  There  will  be no  periodic  payments  of  interest.  The
calculation  of the accrual  of Original Issue  Discount (the difference between
the Issue Price and the  principal amount at maturity of  a LYON) in the  period
during which a LYON remains outstanding will be on a semi-annual bond equivalent
basis  using a 360-day year composed of  twelve 30-day months; such accrual will
commence on the issue date of the LYONs. (Form of LYON, paragraph 1.)  Maturity,
conversion,  purchase by ALZA  at the option  of the Holder,  or redemption of a
LYON will cause Original Issue Discount and interest, if any, to cease to accrue
on such LYON, under the  terms and subject to  the conditions of the  Indenture.
(Section  2.8.) ALZA may not reissue a  LYON that has matured or been converted,
purchased by ALZA  at the  option of a  Holder, redeemed  or otherwise  canceled
(except for registration of transfer, exchange or replacement thereof). (Section
2.10.)  See "Certain United States Federal Income Tax Considerations -- Original
Issue Discount."

    The LYONs will be issued only in fully registered form, without coupons,  in
denominations  of $1,000  principal amount at  maturity or  an integral multiple
thereof. (Form of LYON, paragraph 11.) LYONs may be presented for conversion  at
the  office of the Conversion Agent and for exchange or registration of transfer
at the office of  the Registrar, each  of which initially  will be the  Trustee.
(Section  2.3.) No service charge will be  made for any registration of transfer
or exchange of LYONs;  however, ALZA may  require payment by a  Holder of a  sum
sufficient  to cover any tax, assessment or other governmental charge payable in
connection therewith. (Section 2.6.)

SUBORDINATION OF LYONS

    Indebtedness evidenced  by  the  LYONs  will be  subordinated  in  right  of
payment,  as set  forth in the  Indenture, to the  prior payment in  full of all
existing and  future  Senior  Indebtedness.  (Section 10.1  and  Form  of  LYON,
paragraph 8.) "Senior Indebtedness" means the principal of (and premium, if any)
and  unpaid interest  on all  present and  future (i)  indebtedness of  ALZA for
borrowed money, (ii) obligations of  ALZA evidenced by bonds, debentures,  notes
or  similar instruments, (iii)  indebtedness incurred, assumed  or guaranteed by
ALZA in connection with the acquisition by  it or a subsidiary of any  business,
properties  or assets (except purchase money indebtedness classified as accounts
payable under  generally accepted  accounting principles),  (iv) obligations  of
ALZA  as lessee under leases required to  be capitalized on the balance sheet of
the lessee under generally accepted accounting principles and leases of property
or assets made as part of any sale and lease-back transaction to which ALZA is a
party, (v) reimbursement  obligations of ALZA  in respect of  letters of  credit
relating   to  indebtedness  or  other  obligations  of  ALZA  that  qualify  as
indebtedness or obligations of the kind referred to in clauses (i) through  (iv)
above  and  (vi) obligations  of  ALZA under  direct  or indirect  guaranties in
respect of, and obligations (contingent  or otherwise) to purchase or  otherwise
acquire,  or  otherwise  to  assure  a  creditor  against  loss  in  respect of,
indebtedness or

                                       10
<PAGE>
obligations of others of the kinds referred to in clauses (i) through (v) above,
in each case unless, in the  instrument creating or evidencing the  indebtedness
or  obligation or pursuant to which the same is outstanding, it is provided that
such indebtedness  or obligation  is not  superior in  right of  payment to  the
LYONs. (Section 1.1.)

    By  reason of such  subordination, in the  event of dissolution, insolvency,
bankruptcy or other similar  proceedings, upon any  distribution of assets,  (i)
the  holders of Senior Indebtedness  will be entitled to  be paid in full before
payment may be made on  the LYONs and the Holders  of LYONs will be required  to
pay over their share of such distribution in respect of the LYONs to the holders
of  Senior Indebtedness until such Senior Indebtedness  is paid in full and (ii)
unsecured creditors of ALZA who  are not Holders of  LYONs or holders of  Senior
Indebtedness  may recover less, ratably, than holders of Senior Indebtedness and
may recover more, ratably, than the Holders of LYONs. (Section 10.2.)

    No payment  of  the  principal  amount at  maturity,  Issue  Price,  accrued
Original  Issue Discount, Redemption Price, Change  in Control Purchase Price or
interest, if any, with respect to any LYONs  may be made, nor may ALZA pay  cash
with  respect to the Purchase  Price or upon conversion  of any LYON (other than
cash in lieu of fractional shares) or  acquire any LYONs except as set forth  in
the  Indenture, if there shall have occurred  and be continuing (i) a default in
any payment with respect to any Senior Indebtedness of ALZA or (ii) an event  of
default  with respect to any Senior  Indebtedness of ALZA permitting the holders
thereof to accelerate the maturity thereof. (Section 10.4.)

    The LYONs will  be effectively  subordinated to  all liabilities,  including
trade   payables  and   capitalized  lease   obligations,  if   any,  of  ALZA's
subsidiaries. Any right  of ALZA to  receive assets of  any of its  subsidiaries
upon  liquidation or reorganization of the  subsidiary (and the consequent right
of the Holders of the LYONs to participate in those assets) will be  effectively
subordinated  to  the claims  of  that subsidiary's  creditors  (including trade
creditors), except to the extent that ALZA is itself recognized as a creditor of
such subsidiary, in which case the claims of ALZA would still be subordinate  to
any  security interests in the assets of such subsidiary and any indebtedness of
such subsidiary senior to that held by ALZA.

    As of April 30, 1994, the  principal amount of Senior Indebtedness was  $1.7
million,  excluding  ALZA's  $249.3  million  principal  amount  of  outstanding
commercial paper, which will be retired with a portion of the proceeds from  the
sale of the LYONs. There are no restrictions in the Indenture on the creation of
additional indebtedness, including Senior Indebtedness.

CONVERSION RIGHTS

    A  Holder of a LYON may convert it  at any time before the close of business
on June   ,  2014; PROVIDED, HOWEVER, that if  a LYON is called for  redemption,
the  Holder may  convert it  at any  time before  the close  of business  on the
Redemption Date. On conversion of  a LYON, ALZA may  elect to deliver shares  of
Common  Stock or  an amount  of cash  determined as  described below.  A LYON in
respect of which a Holder has delivered a Purchase Notice or a Change in Control
Purchase Notice exercising the option of such Holder to require ALZA to purchase
such LYON may be converted only if such notice is withdrawn by a written  notice
of  withdrawal delivered to the  Paying Agent prior to  the close of business on
the Purchase Date or the Change in Control Purchase Date, as the case may be, in
accordance with the terms of the Indenture. (Form of LYON, paragraph 9.)

    The initial Conversion Rate  is           shares of  Common Stock per  LYON,
subject  to adjustment upon the occurrence  of certain events described below. A
Holder otherwise entitled  to a fractional  share of Common  Stock will  receive
cash  in  lieu  of such  fractional  share equal  to  the market  value  of such
fractional share based on the Sale Price on the Trading Day immediately prior to
the Conversion  Date. A  Holder may  convert  a portion  of such  Holder's  LYON
provided  that the portion is $1,000 principal amount at maturity or an integral
multiple thereof. (Sections 11.1 and 11.3 and Form of LYON, paragraph 9.)

    On conversion of a LYON,  a Holder must (i)  complete and manually sign  the
conversion  notice on  the back  of the  LYON (or  complete and  manually sign a
facsimile thereof) and deliver such notice to the Conversion Agent or any  other
office  or agency maintained  for such purpose,  (ii) surrender the  LYON to the
Conversion Agent  or such  other office  or  agency by  physical or  book  entry
delivery, (iii) if required, furnish

                                       11
<PAGE>
appropriate  endorsements and transfer  documents and (iv)  if required, pay all
transfer or similar taxes. The date  on which all of the foregoing  requirements
have  been satisfied  is the  Conversion Date. (Section  11.2 and  Form of LYON,
paragraph 9.)

    On conversion  of  a  LYON, a  Holder  will  not receive  any  cash  payment
representing  accrued Original Issue Discount. ALZA's  delivery to the Holder of
the fixed number of shares of Common Stock (or cash in the applicable amount  as
provided  below)  into which  the LYON  is convertible  (together with  the cash
payment, if any, in lieu of fractional shares) will satisfy ALZA's obligation to
pay the principal amount at maturity of the LYON including the accrued  Original
Issue  Discount attributable to the period from the Issue Date to the Conversion
Date. Thus, the accrued  Original Issue Discount  is deemed to  be paid in  full
rather  than canceled, extinguished or forfeited. (Section 11.2.) The Conversion
Rate will not  be adjusted at  any time during  the term of  the LYONs for  such
accrued Original Issue Discount.

    In  lieu of delivering shares  of Common Stock upon  notice of conversion of
any LYON, ALZA may elect to pay the Holder surrendering a LYON an amount in cash
equal to  the  Sale  Price of  a  share  of  Common Stock  on  the  Trading  Day
immediately  prior to the  Conversion Date multiplied by  the Conversion Rate in
effect on such Trading Day, subject to adjustment upon the occurrence of certain
events described below; PROVIDED, that if such payment of cash is not  permitted
pursuant  to the  provisions of  the Indenture  or otherwise,  ALZA will deliver
shares of Common  Stock (and cash  in lieu  of fractional shares)  as set  forth
below.  Upon conversion of  any LYON, ALZA  shall inform the  Holder through the
Conversion Agent of its  election to deliver  shares of Common  Stock or to  pay
cash  in  lieu  of delivery  of  such shares  no  later than  two  business days
following the Conversion Date. If ALZA elects to deliver shares of Common Stock,
such shares will  be delivered through  the Conversion Agent  no later than  the
seventh  business day following the Conversion Date. If ALZA elects to pay cash,
such cash payment will  be made to  the Holder surrendering  such LYON no  later
than  the fifth business day following  such Conversion Date. (Sections 11.1 and
11.2.) For a  discussion of  the tax  treatment of  a Holder  receiving cash  or
Common  Stock, see "Certain  United States Federal  Income Tax Considerations --
Disposition or Conversion."

    ALZA may not pay cash upon conversion  of any LYON (other than cash in  lieu
of  fractional  shares) if  there has  occurred  and is  continuing an  Event of
Default described under "Events of Default; Notice and Waiver" below (other than
a default in such payment on such LYON). (Section 11.1.)

    The "Sale Price" on any Trading Day  means the closing sale price per  share
for  the Common Stock (or,  if no closing price is  reported, the average of the
bid and ask  prices or,  if more than  one in  either case, the  average of  the
average  bid  and  the average  ask  prices) on  such  date as  reported  in the
composite transactions for  the principal United  States securities exchange  on
which  the Common Stock  is traded or,  if the Common  Stock is not  listed on a
United States  national or  regional  securities exchange,  as reported  by  the
National  Association  of  Securities  Dealers  Automated  Quotation  System.  A
"Trading Day"  means each  day on  which the  securities exchange  or  quotation
system  which  is  used to  determine  the Sale  Price  is open  for  trading or
quotation.

    The Conversion  Rate will  be  adjusted for  dividends or  distributions  on
Common   Stock  payable  in  Common  Stock  or  other  capital  stock  of  ALZA;
subdivisions,  combinations  or  certain  reclassifications  of  Common   Stock;
distributions  to all  holders of  Common Stock  of certain  rights, warrants or
options to purchase Common Stock expiring  within 60 days after the record  date
for  such distribution at a price per share less than the Sale Price at the time
specified in the Indenture; and distributions to such holders of assets or  debt
securities of ALZA or certain rights, warrants or options to purchase securities
of  ALZA (excluding cash  dividends or other cash  distributions from current or
retained earnings  other  than any  Extraordinary  Cash Dividend).  However,  no
adjustment  need be  made if  Holders may participate  in the  transactions on a
basis and with notice that the Board of Directors of ALZA determines to be  fair
and  appropriate or in certain other cases. In cases where the fair market value
of the  assets,  debt securities  or  certain  rights, warrants  or  options  to
purchase securities of ALZA distributed to stockholders exceeds the Average Sale
Price  of the Common  Stock or such  Average Sale Price  exceeds the fair market
value of  the  assets,  debt  securities  or  rights,  warrants  or  options  so
distributed,  by less than $1.00, rather than being entitled to an adjustment in
the Conversion  Rate, the  Holder of  a  LYON upon  conversion thereof  will  be

                                       12
<PAGE>
entitled  to receive, in addition  to the shares of  Common Stock into which the
LYON is convertible, the kind and  amount of assets, debt securities or  rights,
warrants  or options  comprising the  distribution that  such Holder  would have
received if such Holder had converted such LYON immediately prior to the  record
date  for determining the stockholders entitled to receive the distribution. The
Indenture permits ALZA to increase the Conversion  Rate from time to time for  a
period of time not less than 20 business days. (Sections 11.6, 11.7, 11.8, 11.9,
11.10, 11.12 and 11.14 and Form of LYON, paragraph 9.)

    If  ALZA is a party to a consolidation, merger or binding share exchange, or
transfers all or substantially all  of its assets, the  right to convert a  LYON
into  Common Stock may be changed into  a right to convert into securities, cash
or other assets of ALZA or another person. (Section 11.14.)

    In the  event of  a taxable  distribution to  holders of  Common Stock  that
results  in an adjustment of the Conversion  Rate or in the event the Conversion
Rate is increased at the  discretion of ALZA, the Holders  of the LYONs may,  in
certain  circumstances, be  deemed to  have received  a distribution  subject to
United States  federal income  tax as  a dividend.  See "Certain  United  States
Federal Income Tax Considerations -- Constructive Dividend."

REDEMPTION OF LYONS AT THE OPTION OF ALZA

    No  sinking fund is provided for the LYONs. The LYONs will not be redeemable
by ALZA prior to June   ,  1999. Thereafter, ALZA may redeem the LYONs for  cash
as  a whole at  any time, or  from time to time  in part, upon  not less than 30
days' nor more than 60 days' notice  of redemption given by mail to the  Holders
of LYONs. (Sections 3.1 and 3.3 and Form of LYON, paragraphs 5 and 7.)

    The  following table shows Redemption Prices of a  LYON on June   , 1999, at
each June    thereafter prior to  maturity, and at  maturity on June    ,  2014,
which prices reflect the accrued Original Issue Discount calculated to each such
date.  The Redemption Price of a LYON  redeemed between such dates would include
an additional amount reflecting the  additional Original Issue Discount  accrued
since  the next preceding  date in the  table to, but  excluding, the Redemption
Date. (Form of LYON, paragraph 5.)

    If less than all of  the outstanding LYONs are  to be redeemed, the  Trustee
shall select the LYONs to be redeemed in principal amounts at maturity of $1,000

considers fair and appropriate. If a portion of a Holder's LYONs is selected for
partial redemption  and such  Holder  converts a  portion  of such  LYONs,  such
converted  portion shall be deemed to be of the portion selected for redemption.

PURCHASE OF LYONS AT THE OPTION OF THE HOLDER

    On June     , 1999, June      , 2004 and June     , 2009 (each, a  "Purchase
Date")  ALZA will  become obligated  to purchase,  at the  option of  the Holder
thereof, any  outstanding LYON  for which  a written  Purchase Notice  has  been
delivered  by the Holder  to the Paying Agent  or to any  other office or agency
maintained for such purpose at any time from the opening of business on the date
that is 20 business days prior to such Purchase Date until the close of business
on such Purchase Date and for which such Purchase Notice has not been withdrawn,
subject to certain additional conditions. The Purchase Price payable in  respect
of a LYON shall be equal to the Issue Price plus accrued Original Issue Discount
to  the Purchase Date, with  respect to each Purchase Date,  as set forth in the
table below. ALZA,  at its  option, may  elect to  pay the  Purchase Price  with
respect  to  any  particular Purchase  Date  in  cash or  Common  Stock,  or any
combination thereof.  (Section  3.8  and  Form of  LYON,  paragraph  6.)  For  a
discussion of the tax treatment of a Holder receiving cash, Common Stock, or any
combination   thereof,   see   "Certain  United   States   Federal   Income  Tax
Considerations -- Disposition or Conversion."

    ALZA will be required to give notice (the "ALZA Notice") on a date not  less
than  20  business days  prior  to any  Purchase Date  to  all Holders  at their
addresses shown in the  register of the Registrar  (and to beneficial owners  if
required  by applicable law) stating, among  other things, (i) whether ALZA will
pay the Purchase  Price of LYONs  in cash  or Common Stock,  or any  combination
thereof  (and, if a combination, specifying the percentage of the Purchase Price
to be paid  in each  of cash  and Common Stock),  and (ii)  the procedures  that
Holders must follow to require ALZA to purchase LYONs from such Holder. (Section
3.8.)

    The  Purchase  Notice  given by  each  Holder  electing to  require  ALZA to
purchase LYONs  shall state  (i) the  certificate  numbers of  the LYONs  to  be
delivered by such Holder for purchase by ALZA, (ii) the portion of the principal
amount  at maturity of LYONs to be purchased, which portion must be $1,000 or an
integral multiple thereof,  (iii) that such  LYONs are to  be purchased by  ALZA
pursuant  to the applicable provisions  of the LYONs and  (iv) in the event ALZA
elects, pursuant to the ALZA Notice, to  pay the Purchase Price with respect  to
the  applicable Purchase  Date in Common  Stock (in  whole or in  part) but such
Purchase Price  is ultimately  to  be paid  in cash  because  any of  the  other
conditions  to payment of the Purchase Price in Common Stock is not satisfied by
such Purchase  Date, as  described  below, whether  such  Holder elects  (a)  to
withdraw such Purchase Notice as to some or all of the LYONs to which it relates
(stating  the principal amount at maturity  and certificate numbers of the LYONs
as to which such withdrawal shall relate)  or (b) to receive cash in respect  of
the  Purchase Price for all LYONs subject to such Purchase Notice. If the Holder
fails to indicate such Holder's choice with respect to the election described in
clause (iv) above in the  Purchase Notice, such Holder  shall be deemed to  have
elected  to receive cash in respect of  the Purchase Price for all LYONs subject
to such Purchase Notice in such circumstances. (Section 3.8.)

    Any Purchase Notice may be  withdrawn by the Holder  by a written notice  of
withdrawal  delivered  to the  Paying Agent  or  to any  other office  or agency
maintained for such purpose prior to the close of business on the Purchase Date.
The notice of withdrawal  shall state the principal  amount at maturity and  the
certificate  numbers of the LYONs as to  which the withdrawal notice relates and
the principal amount at maturity, if any, which remains subject to the  Purchase
Notice. (Section 3.10.)

    The  table below  shows the Purchase  Prices of  a LYON as  of the specified
Purchase Dates:

<TABLE>
<CAPTION>

</TABLE>

    If ALZA elects to pay the Purchase Price, in whole or in part, in shares  of
Common Stock, the number of shares of Common Stock to be delivered in respect of
the  portion of the Purchase Price to be  paid in Common Stock shall be equal to
such portion of the  Purchase Price divided  by the Market Price  of a share  of
Common  Stock. However, no  fractional shares of Common  Stock will be delivered
upon any purchase by ALZA of LYONs through the delivery of such Common Stock  in
payment, in whole or in part, of the

                                       14
<PAGE>
Purchase  Price. Instead, ALZA will  pay cash based on  the Market Price for all
fractional shares of  Common Stock.  (Section 3.8.) See  "Certain United  States
Federal Income Tax Considerations -- Disposition or Conversion."

    The  "Market Price" means the average of the Sale Prices of the Common Stock
for the five Trading  Day period ending  on the third Trading  Day prior to  the
applicable  Purchase  Date,  appropriately  adjusted to  take  into  account the
occurrence during the seven Trading Days preceding such Purchase Date of certain
events that would result in an adjustment of the Conversion Rate with respect to
the Common Stock.  Because the Market  Price of the  Common Stock is  determined
prior  to the applicable  Purchase Date, Holders  of LYONs bear  the market risk
with respect to the value of the Common Stock to be received from the date  such
Market  Price is  determined to  such Purchase  Date. ALZA  may elect  to pay in
Common Stock only if the information necessary to calculate the Market Price  is
reported  in  THE WALL  STREET JOURNAL  or another  daily newspaper  of national
circulation. (Section 3.8.)

    Upon determination of the actual number  of shares of Common Stock  issuable
in   accordance  with   the  foregoing   provisions,  ALZA   will  publish  such
determination in THE WALL STREET JOURNAL or another daily newspaper of  national
circulation. (Section 3.8.)

    ALZA's  right to purchase LYONs,  in whole or in  part, with Common Stock is
subject to ALZA satisfying various conditions, including (i) the registration of
the Common Stock under the Securities  Act and the Exchange Act, if  applicable,
and (ii) any necessary qualification or registration under applicable state laws
or the availability of an exemption from such qualification and registration and
compliance with other applicable federal securities laws. If such conditions are
not  satisfied with respect  to a Holder  or Holders by  the Purchase Date, ALZA
will pay the  Purchase Price of  the LYONs of  such Holder or  Holders in  cash.
(Section  3.8.) See "Certain United States  Federal Income Tax Considerations --
Disposition or Conversion." ALZA  may not change the  form of consideration  (or
components thereof) to be paid once ALZA has given the ALZA Notice to Holders of
LYONs,  except as described  in the second sentence  of this paragraph. (Section
3.8.)

    ALZA will comply with the provisions of Rule 13e-4, Rule 14e-1 and any other
tender offer rules under the Exchange Act which may then be applicable and  will
file Schedule 13E-4 or any other schedule required thereunder in connection with
any offer by ALZA to purchase LYONs at the option of Holders. (Section 3.13.)

    Payment  of the Purchase  Price for a  LYON for which  a Purchase Notice has
been delivered and not  validly withdrawn is conditioned  upon delivery of  such
LYON  (together with necessary endorsements) to the Paying Agent or to any other
office or agency maintained for such purpose  at any time (whether prior to,  on
or  after the  Purchase Date) after  delivery of such  Purchase Notice. (Section
3.8.) Payment of the Purchase Price for  a LYON will be made promptly  following
the  later of the Purchase  Date or the time of  delivery of such LYON. (Section
3.10.) If the Paying Agent holds, in accordance with the terms of the Indenture,
money or securities sufficient  to pay the  Purchase Price of  such LYON on  the
business  day following the Purchase Date, then, on and after the Purchase Date,
such LYON will cease to be outstanding and Original Issue Discount on such  LYON
will  cease to  accrue and  will be  deemed paid,  whether or  not such  LYON is
delivered to the Paying Agent  or to any other  office or agency maintained  for
such  purpose, and all other rights of the Holder will terminate (other than the
right to receive the Purchase Price upon delivery of the LYON). (Section 2.8.)

    ALZA's ability to purchase LYONs  with cash may be  limited by the terms  of
its  then-existing  borrowing agreements.  No LYONs  may  be purchased  for cash
pursuant to  the  provisions  described  above if  there  has  occurred  and  is
continuing  an Event of  Default described under "Events  of Default; Notice and
Waiver" below (other than a  default in the payment  of the Purchase Price  with
respect to such LYONs). (Section 3.10.)

CHANGE IN CONTROL PERMITS PURCHASE OF LYONS AT THE OPTION OF THE HOLDER

    In  the event of any Change in Control of ALZA occurring on or prior to June
  , 1999, each  Holder of LYONs  will have  the right, at  the Holder's  option,
subject    to    the   terms    and    conditions   of    the    Indenture,   to

                                       15
<PAGE>
require ALZA to become obligated to purchase all or any part (provided that  the
principal  amount at maturity must be $1,000 or an integral multiple thereof) of
the Holder's LYONs on the date that is 35 business days after the occurrence  of
such  Change in Control (the "Change in  Control Purchase Date") at a cash price
equal to the Issue Price plus accrued  Original Issue Discount to the Change  in
Control Purchase Date (the "Change in Control Purchase Price"). (Section 3.9 and
Form  of  LYON, paragraph  6.)  See "Certain  United  States Federal  Income Tax
Considerations -- Disposition or Conversion."

    Within 15 business days  after the Change in  Control, ALZA is obligated  to
give notice regarding the Change in Control to the Trustee and to all Holders of
LYONs  at  their  addresses shown  in  the  register of  the  Registrar  (and to
beneficial owners  if required  by applicable  law), which  notice shall  state,
among  other things, (i)  the date of  such Change in  Control and, briefly, the
events causing such Change in Control, (ii) the last date by which the Change in
Control Purchase Notice  must be  given, (iii)  the Change  in Control  Purchase
Date,  (iv) the  Change in Control  Purchase Price, (v)  briefly, the conversion
rights of the  LYONs, (vi)  the name  and address of  the Paying  Agent and  the
Conversion  Agent, (vii) the Conversion Rate and any adjustments thereto, (viii)
that LYONs as to which a Change in Control Purchase Notice has been given may be
converted into Common Stock  only if the Change  in Control Purchase Notice  has
been  withdrawn in  accordance with  the terms  of the  Indenture, (ix)  a brief
description of  these  rights and  the  procedures  the Holder  must  follow  to
exercise  these  rights, and  (x)  the procedures  for  withdrawing a  Change in
Control Purchase Notice. ALZA will cause a  copy of such notice to be  published
in  THE WALL STREET JOURNAL or  another daily newspaper of national circulation.
(Section 3.9.)

    To exercise this right, the Holder must deliver written notice (a "Change in
Control Purchase Notice") to the Paying Agent  or to any other office or  agency
maintained  for such purpose of the exercise of such right prior to the close of
business on the Change in Control Purchase Date. The Change in Control  Purchase
Notice  shall state (i) the certificate numbers  of the LYONs to be delivered by
the Holder  thereof for  purchase by  ALZA, (ii)  the portion  of the  principal
amount  at maturity of LYONs to be purchased, which portion must be $1,000 or an
integral multiple thereof, and (iii) that such LYONs are to be purchased by ALZA
pursuant to the applicable provisions of the LYONs. (Section 3.9.)

    Any Change in Control Purchase  Notice may be withdrawn  by the Holder by  a
written  notice of  withdrawal delivered  to the  Paying Agent  or to  any other
office or agency maintained for such purpose  prior to the close of business  on
the  Change in Control Purchase  Date. The notice of  withdrawal shall state the
principal amount at  maturity and  the certificate numbers  of the  LYONs as  to
which  the withdrawal  notice relates and  the principal amount  at maturity, if
any, that  remains subject  to a  Change in  Control Purchase  Notice.  (Section
3.10.)

    Payment  of the  Change in  Control Purchase  Price for  a LYON  for which a
Change in Control Purchase Notice has  been delivered and not validly  withdrawn
is conditioned upon delivery of such LYON (together with necessary endorsements)
to  the  Paying Agent  or  to any  other office  or  agency maintained  for such
purpose, at  any time  (whether prior  to, on  or after  the Change  in  Control
Purchase  Date) after  the delivery of  such Change in  Control Purchase Notice.
(Section 3.9.) Payment  of the Change  in Control Purchase  Price for such  LYON
will be made promptly following the later of the Change in Control Purchase Date
or the time of delivery of such LYON. (Section 3.10.) If the Paying Agent holds,
in  accordance with  the terms  of the  Indenture, money  sufficient to  pay the
Change in Control Purchase Price of such LYON on the business day following  the
Change  in Control Purchase Date, then, on  and after such date, such LYON shall
cease to be outstanding and Original Issue  Discount on such LYON will cease  to
accrue  and will be  deemed paid, whether or  not such LYON  is delivered to the
Paying Agent or to any other office  or agency maintained for such purpose,  and
all  other rights of the Holder shall terminate (other than the right to receive
the Change in Control Purchase Price upon delivery of the LYON). (Section 2.8.)

                                       16
<PAGE>
    Under  the  Indenture, a  "Change  in Control"  of  ALZA is  deemed  to have
occurred  at  such  time  as  (i)  any  person  (including  its  Affiliates  and
Associates)  other than ALZA, its subsidiaries  or their employee benefit plans,
files a Schedule 13D or 14D-1 (or  any successor schedule, form or report  under
the Exchange Act) disclosing that such person has become the Beneficial Owner of
50%  or more  of ALZA's  Voting Stock,  or (ii)  there shall  be consummated any
consolidation or merger of ALZA in which ALZA is not the continuing or surviving
corporation or pursuant  to which the  Voting Stock of  ALZA would be  converted
into cash, securities or other property, in each case other than a consolidation
or  merger of ALZA in which the holders  of the Voting Stock of ALZA immediately
prior to the consolidation  or merger have, directly  or indirectly, at least  a
majority  of the Voting Stock of the surviving corporation immediately after the
consolidation or merger. (Section 3.9.)

    "Voting Stock" means,  with respect  to any  person, capital  stock of  such
person  having general  voting power  under ordinary  circumstances to  elect at
least a majority of the board of directors, managers or trustees of such  person
(irrespective  of whether or not at the time capital stock of any other class or
classes shall have or might have voting power by reason of the happening of  any
contingency). (Section 3.9.)

    ALZA will comply with the provisions of Rule 13e-4, Rule 14e-1 and any other
tender  offer rules under the Exchange Act which may then be applicable and will
file Schedule 13E-4 or any other schedule required thereunder in connection with
any offer by ALZA to  purchase LYONs at the option  of Holders upon a Change  in
Control. (Section 3.13.) The Change in Control purchase feature of the LYONs may
in  certain circumstances make  more difficult or discourage  a takeover of ALZA
and, thus, the removal of incumbent  management. The Change in Control  purchase
feature,  however, is not  the result of management's  knowledge of any specific
effort to accumulate  shares of Common  Stock or  to obtain control  of ALZA  by
means of a merger, tender offer, solicitation or otherwise, or part of a plan by
management to adopt a series of anti-takeover provisions. Instead, the Change in
Control  purchase feature is a standard  term contained in other LYONs offerings
that have been marketed by the Underwriter and the terms of such feature  result
from negotiations between ALZA and the Underwriter.

    If  a Change in Control  were to occur, there can  be no assurance that ALZA
would have sufficient funds to pay the Change in Control Purchase Price for  all
LYONs  tendered by the Holders thereof.  In addition, ALZA's ability to purchase
LYONs with  cash may  be limited  by the  terms of  its then-existing  borrowing
agreements. Payment of the Change in Control Purchase Price will be subordinated
to the repayment of Senior Indebtedness. See "Subordination of LYONs." A default
by  ALZA on  its obligation to  pay the  Change in Control  Purchase Price would
result in an Event of Default and  could result in acceleration of the  maturity
of  other indebtedness of ALZA at the time outstanding pursuant to cross-default
provisions. See  "Events  of  Default;  Notice and  Waiver."  No  LYONs  may  be
purchased  if there has occurred and is continuing an Event of Default described
under "Events of Default; Notice and Waiver" below (other than a default in  the
payment  of the Change  in Control Purchase  Price with respect  to such LYONs).
(Section 3.10.)

MERGERS AND SALES OF ASSETS BY ALZA

    The Indenture provides that ALZA may not consolidate with or merge into  any
other  person or sell, lease  or otherwise transfer all  or substantially all of
its assets to any other person,  unless, among other things, (i) the  resulting,
surviving  or transferee person  (if other than ALZA)  is organized and existing
under the  laws of  the United  States, any  state thereof  or the  District  of
Columbia  and such  person expressly assumes  all obligations of  ALZA under the
LYONs and  the  Indenture and  (ii)  ALZA or  such  successor person  shall  not
immediately thereafter be in default under the Indenture. Upon the assumption of
ALZA's  obligations by such  a person in such  circumstances, subject to certain
exceptions, ALZA shall be  discharged from all obligations  under the LYONs  and
the Indenture. (Section 5.1.) Certain of the foregoing transactions occurring on
or  prior to June  , 1999 could result in a Change in Control of ALZA permitting
each Holder to require ALZA  to purchase the LYONs  of such Holder as  described
above. (Section 3.9.)

EVENTS OF DEFAULT; NOTICE AND WAIVER

    The  Indenture provides that if an  Event of Default specified therein shall
have occurred and be continuing, either the  Trustee or the Holders of not  less
than 25% in aggregate principal amount at maturity of the LYONs then outstanding
may  declare  the Issue  Price of  the  LYONs plus  the Original  Issue Discount

                                       17
<PAGE>
on the LYONs accrued to the date  of such declaration to be immediately due  and
payable.  In the case of  certain events of bankruptcy  or insolvency, the Issue
Price of  the LYONs  plus the  Original Issue  Discount accrued  thereon to  the
occurrence  of such event shall automatically  become and be immediately due and
payable. See "Subordination of LYONs." If any LYONs are declared due and payable
before  their  stated  maturity,  the   holders  of  Senior  Indebtedness   then
outstanding  shall be entitled to receive payment  in full of all amounts due or
to become due on or with respect to all Senior Indebtedness, or provision  shall
be made for payment of such amounts, before the Holders of LYONs are entitled to
receive  any  payment on  account of  the LYONs.  (Section 10.3.)  Under certain
circumstances, the  Holders  of a  majority  in aggregate  principal  amount  at
maturity of the outstanding LYONs may rescind any such acceleration with respect
to  the LYONs and its consequences. (Section  6.2.) Interest shall accrue and be
payable on demand upon a default in the payment of principal amount at maturity,
Issue Price, accrued Original Issue Discount, Redemption Price, Purchase  Price,
Change  in  Control Purchase  Price  or cash  or shares  of  Common Stock  to be
delivered on conversion of  LYONs, in each  case to the  extent that payment  of
such interest shall be legally enforceable. (Form of LYON, paragraph 1.)

    Under the Indenture, an Event of Default is defined as any of the following:
(i) default in payment of the principal amount at maturity, Issue Price, accrued
Original  Issue Discount, Redemption Price, Purchase  Price or Change in Control
Purchase Price  with respect  to any  LYON  when such  becomes due  and  payable
(whether  or not payment is prohibited by the provisions of the Indenture), (ii)
failure by ALZA to deliver  shares of Common Stock or  pay cash in lieu  thereof
when  such Common Stock or cash is required to be delivered or paid, as the case
may be, following conversion of a LYON, (iii) failure by ALZA to comply with any
of its other agreements in the LYONs  or the Indenture upon the receipt by  ALZA
of  notice of such default by the Trustee or  by Holders of not less than 25% in
aggregate principal amount at maturity of the LYONs then outstanding and  ALZA's
failure  to  cure such  default within  60 days  after receipt  by ALZA  of such
notice, (iv) default  under any  mortgage, indenture or  instrument under  which
there  may  be  issued  or  by  which there  may  be  secured  or  evidenced any
indebtedness for money borrowed  of ALZA or  any Consolidated Subsidiary,  which
default  shall have  resulted in  such indebtedness,  in an  aggregate principal
amount exceeding $25,000,000, becoming or  being declared due and payable  prior
to the date on which it would otherwise have become due and payable without such
indebtedness  being  discharged or  such acceleration  having been  rescinded or
annulled, or there having been deposited in  trust a sum of money sufficient  to
discharge  such indebtedness within  a period of  30 days after  the giving of a
Notice of Default by the Trustee or by Holders of not less than 25% in aggregate
principal amount  at maturity  of the  LYONs then  outstanding, or  (v)  certain
events of bankruptcy or insolvency. (Section 6.1.)

    The  Trustee shall  give notice  to Holders of  the LYONs  of any continuing
default known  to the  Trustee  within 90  days  after the  occurrence  thereof;
provided,  that the Trustee  may withhold such  notice if it  determines in good
faith that withholding the notice is  in the interests of the Holders.  (Section
7.5.)

    The  Holders of a majority in aggregate  principal amount at maturity of the
outstanding LYONs  may direct  the  time, method  and  place of  conducting  any
proceeding  for any remedy available  to the Trustee or  exercising any trust or
power conferred on  the Trustee, provided  that such direction  shall not be  in
conflict with any law or the Indenture and subject to certain other limitations.
(Section  6.5.)  Before proceeding  to  exercise any  right  or power  under the
Indenture at the  direction of such  Holders, the Trustee  shall be entitled  to
receive  from such Holders  reasonable security or  indemnity satisfactory to it
against any  cost,  liability  or expense  which  might  be incurred  by  it  in
complying  with any such direction. No Holder of any LYON will have any right to
pursue any remedy with respect  to the Indenture or  the LYONs, unless (i)  such
Holder  shall have previously  given the Trustee written  notice of a continuing
Event of Default, (ii) the Holders of at least 25% in aggregate principal amount
at maturity of the outstanding  LYONs shall have made  a written request to  the
Trustee  to pursue such remedy, (iii) such Holder or Holders have offered to the
Trustee reasonable security or indemnity  satisfactory to the Trustee, (iv)  the
Holders  of  a  majority  in  aggregate  principal  amount  at  maturity  of the
outstanding LYONs have not given the Trustee a direction inconsistent with  such
request  within 60 days after receipt of  such request and (v) the Trustee shall
have failed to comply with the request within such 60-day period. (Section 6.6.)

                                       18
<PAGE>
    Notwithstanding the  foregoing,  the right  of  any Holder  (i)  to  receive
payment of the principal amount at maturity, Issue Price, accrued Original Issue
Discount,  Redemption Price, Purchase Price or  Change in Control Purchase Price
with respect to any LYON and any interest in respect of a default in the payment
of any such amounts  on such LYON, on  or after the due  date expressed in  such
LYON  or (ii)  to institute  suit for  the enforcement  of any  such payments or
conversion or (iii) to convert  LYONs (including, without limitation, the  right
to  receive cash in lieu of Common Stock  upon conversion if ALZA has elected to
pay cash  with respect  thereto) shall  not be  impaired or  adversely  affected
without such Holder's consent. (Section 6.7.) The Holders of at least a majority
in  aggregate principal amount at maturity of the outstanding LYONs may waive an
existing default and its consequences, other than (i) any default in any payment
on the LYONs, (ii) any default with respect to the conversion rights of LYONs or
(iii) any default in respect of certain covenants or provisions in the Indenture
which may not  be modified without  the consent of  the Holder of  each LYON  as
described in "Modification" below. (Section 6.4.)

    ALZA  will be required to furnish to  the Trustee annually a statement as to
any default by ALZA in the  performance and observance of its obligations  under
the Indenture. (Section 4.3.)

MODIFICATION

    Modification  and amendment of the Indenture or the LYONs may be effected by
ALZA and the Trustee with the consent of the Holders of not less than a majority
in aggregate principal amount at maturity of the LYONs then outstanding. Without
the consent of each  Holder affected thereby, however,  no amendment may,  among
other things, (i) reduce the principal amount at maturity, Issue Price, Purchase
Price,  Change in Control Purchase Price, Redemption Price or the amount of cash
payable in respect of conversion upon  ALZA's election to pay cash with  respect
thereto,  or extend the stated maturity of any  LYON or alter the manner or rate
of accrual of Original Issue Discount or  interest, or make any LYON payable  in
money  or  securities  other than  that  stated  in the  LYON,  (ii)  reduce the
principal amount at maturity of LYONs whose Holders must consent to an amendment
or any  waiver  under  the  Indenture, (iii)  modify  the  Indenture  provisions
relating  to such  amendments or  waivers, (iv)  make any  change that adversely
affects the right to convert any LYON or the right to require ALZA to purchase a
LYON (including, without limitation, the right to receive cash in lieu of Common
Stock upon conversion or purchase other than elimination of ALZA's option to pay
cash in lieu of delivering shares  of Common Stock upon conversion as  described
below), (v) modify the provisions of the Indenture relating to the subordination
of  the LYONs in a manner that adversely affects the rights of any Holder of the
LYONs, or (vi) impair  the right to  institute suit for  the enforcement of  any
payment  with  respect  to,  or  conversion of,  the  LYONs.  (Section  9.2.) In
addition, no  amendment may  be  made to  the  subordination provisions  of  the
Indenture that adversely affects the rights of any holder of Senior Indebtedness
then  outstanding, unless the  holders of such  Senior Indebtedness (as required
pursuant to  the terms  of such  Senior Indebtedness)  consent to  such  change.
(Section 9.2.)

    Without  the consent of any Holder of  LYONs, ALZA and the Trustee may amend
the Indenture  to (i)  cure any  ambiguity, omission,  defect or  inconsistency,
provided  that such amendment does not materially adversely affect the rights of
any Holder, (ii) provide  for the assumption by  a successor corporation of  the
obligations  of ALZA under the Indenture, (iii) provide for uncertificated LYONs
in addition to certificated  LYONs so long as  such uncertificated LYONs are  in
registered  form for United  States federal income  tax purposes, (iv) eliminate
ALZA's option to  pay cash in  lieu of  delivering shares of  Common Stock  upon
conversion  of LYONs (other  than cash in  lieu of fractional  shares and except
with respect  to elections  already made),  (v) make  any change  that does  not
adversely  affect the rights of  any Holder of LYONs or  (vi) make any change to
comply with the Trust Indenture Act of  1939, as amended, or any requirement  of
the  Commission in connection with the qualification of the Indenture under such
act. (Section 9.1.)

DISCHARGE OF THE INDENTURE

    ALZA may  satisfy  and discharge  its  obligations under  the  Indenture  by
delivering  to  the  Trustee  for  cancellation  all  outstanding  LYONs  or  by
depositing with the Trustee, after the  LYONs have become due and payable,  cash
(or, if permitted by the terms of the Indenture, other securities) sufficient to
pay  at stated maturity all  of the outstanding LYONs  and paying all other sums
payable under the Indenture by ALZA.

                                       19

INFORMATION CONCERNING THE TRUSTEE

    The Chase Manhattan Bank, N.A. is the Trustee under the Indenture. ALZA  and
its  subsidiaries  may  maintain  deposit  accounts  and  conduct  other banking
transactions with the Trustee in the ordinary course of business.

CLAIMS IN BANKRUPTCY

    If ALZA becomes  the subject of  a voluntary or  involuntary case under  the
United  States Bankruptcy Code, the claim of any Holder of a LYON may, under the
Bankruptcy Code, be limited to the Issue Price of the LYON plus that portion  of
the  Original Issue  Discount that is  deemed to  have accrued from  the date of
issue to the date of the commencement  of the bankruptcy case. In addition,  the
Holders  of  the  LYONs will  be  subordinated  in right  of  payment  to Senior
Indebtedness and effectively subordinated to indebtedness and other  obligations
of ALZA's subsidiaries. See "Subordination of LYONs."

                          DESCRIPTION OF CAPITAL STOCK

    DESCRIPTION  OF CAPITAL STOCK.  ALZA's  authorized capital stock consists of
300,000,000 shares of Common Stock par value $.01 per share, and 100,000  shares
of  Preferred  Stock,  par value  $.01  per  share (the  "Preferred  Stock"). No
Preferred Stock is  outstanding as of  the date of  this Prospectus. For  recent
prices of Common Stock, see "Price Range of Common Stock and Dividend Policy."

    On  March 31, 1994 there were 81,674,400 shares of Common Stock outstanding.
In addition there were  1,966,697 shares of Common  Stock reserved for  issuance
upon  exercise  of outstanding  warrants and  5,832,501  shares of  Common Stock
reserved for issuance under option  and other incentive plans.            shares
have been reserved for issuance upon conversion of the LYONs.

    Holders  of Common Stock are entitled to one vote for each share held on all
matters submitted to a vote of  stockholders. Subject to any superior rights  of
Preferred  Stock, holders of Common  Stock are entitled to  share, on a pro rata
basis, in all assets  remaining after payment of  or provision for  liabilities.
The shares of Common Stock are not subject to redemption. ALZA has the corporate
power to repurchase Common Stock.

    ALZA's  Board  of  Directors  has  authority to  fix  or  alter  the rights,
preferences, privileges, restrictions and other terms of any series of Preferred
Stock, the number  of shares constituting  any such series  and the  designation
thereof. ALZA has no present plans to issue any shares of Preferred Stock.

    ALZA  has a classified  Board of Directors  with directors serving staggered
terms of three  years each.  Directors may not  be removed  by the  stockholders
without  cause. Special meetings of  the stockholders may be  called only by the
Board of Directors, the Chairman of the Board or the President. Nominations  for
election  of  directors  may  be  made  by the  Board  of  Directors  or  by any
stockholder of  record  entitled  to  vote  for  directors,  provided  that  any
stockholder  nominating a candidate for director  must deliver written notice to
the Secretary of ALZA not later than the close of business 60 days in advance of
the stockholders' meeting  or 10  days after  the date  on which  the notice  of
meeting  is first given  to stockholders, whichever  is later. The stockholder's
notice must set  forth certain  information concerning the  stockholder and  the
stockholder's  nominee. No  nominations for director  shall be  presented to any
stockholders' meeting if  not made  in compliance with  such procedures.  ALZA's
bylaws also require that advance notice be given and certain other procedures be
followed with regard to any other business to be brought by a stockholder before
a  meeting of  stockholders. Such procedures  include the delivery  of notice of
such proposal to the Secretary of ALZA  not later than the close of business  60
days  in advance of the meeting or 10 days after the date on which the notice of
meeting is first given to stockholders, whichever is later. The notice must  set
forth  certain information concerning the stockholder and the proposed business,
including any  material  interest  of  the stockholder  in  that  business.  The
provisions  of  ALZA's Certificate  of  Incorporation and  bylaws  governing the
number and classification of the Board of Directors and certain related  matters
cannot be amended without the approval of at least 75% of the Board of Directors
or  the  affirmative vote  of  not less  than  80% of  the  voting power  of the
outstanding shares of voting capital stock. The affirmative vote of at least 80%
of the  voting  power of  the  outstanding shares  of  voting capital  stock  is
required to approve certain business combinations.

                                       20
<PAGE>
    The  provisions of ALZA's Certificate of Incorporation granting the Board of
Directors the authority to  issue Preferred Stock with  such terms as the  Board
may  determine, classifying  ALZA's Board, preventing  stockholders from calling
special meetings of  ALZA's stockholders, and  requiring supermajority votes  in
the  event of certain business combinations may inhibit any change in control of
ALZA.

            CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

    The  following  summary  of  material  United  States  federal  income   tax
considerations  is for general  information only. The summary  is based upon the
Internal Revenue Code of 1986, as amended (the "Code"), its legislative history,
existing and  proposed  regulations  thereunder,  published  rulings  and  court
decisions, all as in effect and existing on the date hereof and all of which are
subject  to change at any time.  The tax treatment of a  Holder of the LYONs may
vary  depending  upon  the   Holder's  particular  situation.  Certain   Holders
(including  insurance companies, tax-exempt organizations, individual retirement
and other tax-deferred accounts, financial institutions, broker-dealers, foreign
corporations, and individuals who  are not citizens or  residents of the  United
States)  may be subject to special rules  not discussed below. This summary does
not discuss the  tax considerations  of subsequent  purchasers of  LYONs and  is
limited  to investors who hold LYONs  as capital assets. Accordingly, purchasers
of LYONs  should  consult  their own  tax  advisors  as to  the  particular  tax
consequences to them of acquiring, holding, converting or otherwise disposing of
the  LYONs, including the  applicability and the  effect of any  state, local or
foreign tax laws and recent changes in applicable tax laws.

    ALZA has been advised  by Mayer, Brown &  Platt, special federal income  tax
counsel  to ALZA, that in the opinion of  such counsel the LYONs will be treated
as indebtedness for  United States  federal income tax  purposes. The  following
discussion  of  tax considerations  assumes that  the LYONs  will be  treated as
indebtedness.

ORIGINAL ISSUE DISCOUNT
    The LYONs are being  issued at a substantial  discount from their  principal
amount  at maturity. For federal income tax purposes, the difference between the
issue price (the first price at which a substantial amount of the LYONs are sold
for money)  and  the principal  amount  at  maturity of  each  LYON  constitutes
Original  Issue  Discount. Holders  of  the LYONs  will  be required  to include
Original Issue Discount in income periodically over the term of the LYONs before
the receipt of  the cash, Common  Stock or other  payments attributable to  such
income.

    A  Holder of  a LYON  must include  in gross  income for  federal income tax
purposes the sum of the daily  portions of Original Issue Discount with  respect
to the LYON for each day during the taxable year or portion of a taxable year on
which  such Holder holds the LYON ("Accrued Original Issue Discount"). The daily
portion is determined by allocating to each day of the accrual period a PRO RATA
portion of  an amount  equal to  the adjusted  issue price  of the  LYON at  the
beginning  of the accrual period multiplied by the yield to maturity of the LYON
(determined by compounding at the close of each accrual period and adjusted  for
the  length of the accrual  period). Under the Code,  the accrual period will be
each six month period which ends on the day in each calendar year  corresponding
to  the maturity date  of the LYON or  the date six  months before such maturity
date. The  information returns  provided  to holders  and the  Internal  Revenue
Service  (the "Service")  by the  Company regarding the  accrual of  OID will be
based on these six month accrual periods. Treasury regulations, however,  permit
a Holder to select an accrual period of any length and to vary the length of the
accrual  period over the term of the debt instrument, provided that each accrual
period is no longer  than one year  and each scheduled  payment of principal  or
interest  occurs on the final day of an accrual period or on the first day of an
accrual period. The adjusted issue price of the LYON at the start of any accrual
period is the issue price  of the LYON increased  by the Accrued Original  Issue
Discount  for each prior accrual period. Under these rules, Holders will have to
include in gross income increasingly greater amounts of Original Issue  Discount
in  each successive accrual period. ALZA will be required to furnish annually to
the Service and to certain noncorporate Holders information regarding the amount
of Original Issue Discount attributable to that year.

DISPOSITION OR CONVERSION
    A Holder's  basis  for  determining  gain  or loss  on  the  sale  or  other
disposition  of a LYON will be increased  by any Accrued Original Issue Discount
includable in such Holder's gross income. Gain or loss

                                       21
<PAGE>
upon a sale or other  disposition (including a sale to  ALZA or receipt of  cash
from ALZA on conversion) of a LYON, except as described below, will generally be
capital gain or loss, which will be long term if the LYON has been held for more
than one year.

    A  Holder's conversion of a LYON for Common Stock is generally not a taxable
event (except with respect to  cash received in lieu  of a fractional share).  A
Holder's  obligation to include  in gross income the  daily portions of Original
Issue Discount with respect to a  LYON will prospectively terminate on the  date
of  conversion. The Holder's basis in the Common Stock received on conversion of
a LYON  will be  the same  as the  Holder's basis  in the  LYON at  the time  of
conversion (exclusive of any tax basis allocable to a fractional share).

    If the Holder elects to exercise the option to tender the LYONs to ALZA on a
Purchase  Date  and ALZA  issues Common  Stock in  satisfaction of  the Purchase
Price, such exchange  is generally not  a taxable event  for federal income  tax
purposes,  and therefore, neither  gain nor loss would  be recognized, except as
described below with regard to fractional shares. In such event, a Holder's  tax
basis  in the  Common Stock  received in the  exchange will  be the  same as the
Holder's tax basis in the LYON tendered to ALZA in exchange therefor  (exclusive
of any tax basis allocable to a fractional share). If the original Holder elects
to exercise his or her option to tender the LYONs to ALZA on a Purchase Date and
ALZA  delivers cash and Common Stock in  satisfaction of the Purchase Price, the
Holder would recognize neither  gain nor loss. In  such event, the Holder's  tax
basis  in the  Common Stock  received in the  exchange will  be the  same as the
Holder's tax basis in the LYON tendered to ALZA in exchange therefor,  exclusive
of any basis allocable to fractional shares as described below, increased by the
amount  of  gain recognized  on the  exchange (other  than gain  recognized with
respect to a fractional share) and decreased  by the amount of cash received  in
the exchange.

    The  holding  period for  the  Common Stock  received  in the  conversion or
exchange will  include the  holding period  for  the LYON  tendered to  ALZA  in
exchange  therefor, except that the holding  period of Common Stock allocable to
Accrued Original Issue Discount  may commence on the  day following the date  of
conversion.  Gain or loss upon  a sale or other  disposition of the Common Stock
received on conversion or exchange of a LYON will be capital gain or loss if the
Common Stock is a capital asset in the hands of the Holder.

    If the Holder elects to  exercise his or her option  to tender the LYONs  to
ALZA  on a Purchase Date and ALZA  delivers cash in satisfaction of the Purchase
Price or if a Holder elects to exercise his or her option to tender the LYON  to
ALZA  for cash on a Change in Control Purchase Date, such an exchange would be a
taxable sale. Also, if the holder  elects to exercise the conversion option  and
ALZA delivers cash equal to the value of the shares of the Common Stock, such an
exchange  would be a  taxable sale. The  Holder would recognize  capital gain or
loss upon  the sale,  measured by  the  difference between  the amount  of  cash
transferred by ALZA to the Holder and the Holder's basis in the LYON.

    Under the current advance ruling policy of the IRS, cash received in lieu of
a  fractional share of Common Stock upon conversion or purchase of a LYON should
be treated as a payment  in exchange for the  fractional share interest in  such
Common  Stock. Accordingly, if the Common Stock  is a capital asset in the hands
of the Holder, the receipt of cash in lieu of a fractional share of Common Stock
should generally  result  in capital  gain  or loss,  if  any (measured  by  the
difference  between the cash received for  the fractional share and the Holder's
tax basis in a fractional share).

CONSTRUCTIVE DIVIDEND

    If at any time  ALZA makes a distribution  of property to stockholders  that
would  be taxable to such  stockholders as a dividend  for United States federal
income tax purposes (for example, distributions of evidences of indebtedness  or
assets  of ALZA, but  generally not stock  dividends or rights  to subscribe for
Common Stock) and,  pursuant to the  antidilution provisions of  the LYONs,  the
Conversion Rate of the LYONs is increased, such increase may be deemed to be the
payment of a taxable dividend to Holders of the LYONs.

                                  UNDERWRITING

    Merrill  Lynch, Pierce, Fenner &  Smith Incorporated (the "Underwriter") has
agreed, subject  to the  terms  and conditions  of  the Purchase  Agreement,  to
purchase  $825,000,000 aggregate principal amount at  maturity of the LYONs from
ALZA. The  Underwriter has  advised ALZA  that it  proposes to  offer the  LYONs
directly to the public at the offering price set forth on the cover page of this
Prospectus.  After  the  initial  public offering,  the  offering  price  may be
changed. The  LYONs  are  offered  subject to  receipt  and  acceptance  by  the
Underwriter  and  to certain  other conditions,  including  the right  to reject
orders in whole or in part.

    ALZA has granted the  Underwriter an option  for 30 days  after the date  of
this Prospectus to purchase up to an additional $123,750,000 aggregate principal
amount  at maturity of  LYONs to cover  over-allotments, if any,  at the initial
public offering price less the underwriting  discount as set forth on the  cover
page  of this Prospectus, plus accrued  Original Issue Discount, if any, accrued
from the Issue Date, computed on a semi-annual bond equivalent basis.

    ALZA  has  agreed  to  indemnify  the  Underwriter  against  certain   civil
liabilities,  including liabilities under the  Securities Act, and to contribute
to payments the Underwriter may be required to make in respect thereof.

    ALZA has agreed with the Underwriter not  to sell, offer to sell, grant  any
option  for the  sale of,  or otherwise  dispose of  or transfer  any securities
similar to the LYONs or any Common  Stock or any securities convertible into  or
exercisable  or exchangeable for such securities or Common Stock for a period of
90 days after the date of this  Prospectus without the prior written consent  of
the  Underwriter other  than Common  Stock issuable  upon the  exchange of LYONs
offered hereby, Common Stock issued or  sold pursuant to employee benefit  plans
and  dividend reinvestment plans, Common Stock issued upon exercise of currently
outstanding  options  or  warrants,  or  certain  privately  issued   restricted
securities.

    Application has been made to list the LYONs on the New York Stock Exchange.

    The  Underwriter  has  previously marketed  (and  anticipates  continuing to
market) securities  of other  issuers  under the  trademark "LYONs."  The  LYONs
offered  by ALZA hereby contain certain terms and provisions which are different
from such other  previously marketed LYONs,  the terms and  provisions of  which
also vary. See "Description of LYONs."

    From  time  to  time the  Underwriter  and  certain of  its  affiliates have
performed, and  may  in the  future  perform, investment  banking  or  financial
advisory services for ALZA.

                                 LEGAL MATTERS

    The validity of the issuance of the LYONs offered hereby will be passed upon
for  ALZA by  Heller, Ehrman, White  & McAuliffe, Palo  Alto, California, ALZA's
counsel. Shearman & Sterling, San Francisco, California, will act as counsel  to
the  Underwriter. Mayer, Brown  & Platt, Chicago, Illinois,  will act as special
counsel to  the Underwriter  and as  special United  States federal  income  tax
counsel to ALZA. At April 30, 1994, Julian N. Stern, a member of Heller, Ehrman,
White  &  McAuliffe who  is also  a director  and the  Secretary of  ALZA, owned
beneficially 158,645 shares of Common Stock (including options and warrants) and
other attorneys in that firm owned, in the aggregate, 700 shares of Common Stock
(including warrants).

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

    Section  102 of the Delaware General Corporation Law allows a corporation to
eliminate  the  personal  liability  of  directors  of  a  corporation  to   the
corporation  or to any of  its stockholders for monetary  damage for a breach of
his fiduciary duty as a director, except in the case where the director breached
his duty  of  loyalty, failed  to  act in  good  faith, engaged  in  intentional
misconduct  or knowingly violated a law, authorized the payment of a dividend or
approved a stock repurchase in violation  of Delaware corporate law or  obtained
an  improper personal  benefit. ALZA's  Certificate of  Incorporation contains a
provision that eliminates directors' personal liability as set forth above.

    Section 145 of the  Delaware General Corporation  Law, as amended,  provides
that  a  corporation may  indemnify  any person  who  was or  is  a party  or is
threatened to be made  a party to any  threatened, pending or completed  action,
suit or proceeding, whether civil, criminal, administrative or investigative, by
reason  of the fact that he is or  was a director, officer, employee or agent of
the corporation or is or was serving at its request in such capacity in  another
corporation  or  business  association  against  expenses  (including attorneys'
fees), judgments, fines and amounts  paid in settlement actually and  reasonably
incurred  by him in connection with such  action, suit or proceeding if he acted
in good faith and in a manner he reasonably believed to be in or not opposed  to
the  best interests of the corporation and,  with respect to any criminal action
or proceeding, had no reasonable cause to believe his conduct was unlawful.

    In addition, Article 9  of ALZA's Certificate  of Incorporation provides  as
follows:

    LIMITATION OF LIABILITY AND INDEMNIFICATION OF DIRECTORS.

    (a)   ELIMINATION  OF CERTAIN  LIABILITY OF DIRECTORS.   No  director of the
corporation shall be personally  liable to the  corporation or its  stockholders
for  monetary damages  for breach  of fiduciary duty  as a  director, except for
liability (i)  for  any  breach  of  the  director's  duty  of  loyalty  to  the
corporation or its stockholders, (ii) for acts or omissions not in good faith or
which  involve intentional misconduct or a knowing violation of law, (iii) under
Section 174 of the Delaware General Corporation Law or (iv) for any  transaction
from which the director derived an improper personal benefit.

    (b)  INDEMNIFICATION AND INSURANCE.

        (1)   RIGHT TO INDEMNIFICATION.  Each person  who was or is made a party
    or is threatened to be made a party to or is involved in any action, suit or
    proceeding, whether civil, criminal, administrative or

                                      II-1
<PAGE>
    investigative (a "proceeding"), because he or she, or a person of whom he or
    she is the  legal representative, is  or was  a director or  officer of  the
    corporation  or is  or was serving  at the  request of the  corporation as a
    director, officer,  employee  or  agent  of  another  corporation  or  of  a
    partnership,  joint venture,  trust or  other enterprise  (including service
    with respect to employee benefit plans), whether the basis of the proceeding
    is alleged action in an official  capacity as a director, officer,  employee
    or  agent or  in any  other capacity while  serving as  a director, officer,
    employee or agent, shall be indemnified and held harmless by the corporation
    to the fullest extent authorized by the Delaware General Corporation Law, as
    the same exists or may  hereafter be amended (but, in  the case of any  such
    amendment, only to the extent that such amendment permits the corporation to
    provide   broader  indemnification  rights  than   that  law  permitted  the
    corporation  to  provide  before  such  amendment),  against  all   expense,
    liability  and loss (including attorneys' fees, judgments, penalties, fines,
    Employee Retirement Income Security Act  of 1974 excise taxes or  penalties,
    and  amounts  paid  or to  be  paid  in settlement)  reasonably  incurred or
    suffered by such person in connection therewith; provided, however, that the
    corporation shall  indemnify  any  such person  seeking  indemnification  in
    connection with a proceeding (or part thereof) initiated by such person only
    if the proceeding (or part thereof) was authorized by the Board of Directors
    of  the corporation. Such indemnification shall  continue as to a person who
    has ceased to be a director, officer,  employee or agent and shall inure  to
    the  benefit of his or her heirs, executors and administrators. The right to
    indemnification conferred by this  Section shall be  a contract right  which
    may  not be retroactively amended and shall  include the right to be paid by
    the corporation the expenses  incurred in defending  any such proceeding  in
    advance  of its final disposition; provided,  however, that, if the Delaware
    General Corporation Law requires, the payment of such expenses incurred by a
    director or officer in his or her capacity as a director or officer (and not
    in any other capacity  in which service  was or is  rendered by such  person
    while  a director  or officer,  including, without  limitation, service with
    respect to an employee benefit plan) in advance of the final disposition  of
    the  proceeding shall be  made only upon  delivery to the  corporation of an
    undertaking, by  or on  behalf of  such director  or officer,  to repay  all
    amounts  so advanced if ultimately it shall be determined that such director
    or officer  is  not  entitled  to  be  indemnified  under  this  Section  or
    otherwise. The corporation may, by action of its Board of Directors, provide
    indemnification  to employees  and agents of  the corporation  with the same
    scope and effect as the indemnification of directors and officers.

        (2)  NONEXCLUSIVITY  OF RIGHTS.   The right to  indemnification and  the
    payment  of expenses  incurred in defending  a proceeding in  advance of its
    final disposition conferred in  this Section shall not  be exclusive of  any
    other  right  which  any person  may  have  or hereafter  acquire  under any
    statute, provision of this  Certificate of Incorporation, bylaw,  agreement,
    vote of stockholders or disinterested directors, or otherwise.

        (3)  INSURANCE.  The corporation may maintain insurance, at its expense,
    to  protect  itself and  any  director, officer,  employee  or agent  of the
    corporation or  another corporation,  partnership, joint  venture, trust  or
    other enterprise against any such expense, liability or loss, whether or not
    the  corporation would have the power  to indemnify such person against such
    expense, liability or loss under the Delaware General Corporation Law.

    ALZA has directors  and officers liability  insurance which would  indemnify
the  directors and officers of ALZA against damages arising out of certain kinds
of claims which  might be made  against them  based on their  negligent acts  or
omissions while acting in their capacity as such.

ITEM 17.  UNDERTAKINGS.

    The   undersigned  Registrant  hereby  undertakes   that,  for  purposes  of
determining any liability  under the  Securities Act  of 1933,  as amended  (the
"Securities  Act"), each  filing of the  Registrant's annual  report pursuant to
Section 13(a)  or Section  15(d) of  the  Securities Exchange  Act of  1934,  as
amended (and, where applicable, each filing of an employee benefit plan's annual
report  pursuant to  Section 15(d)  of the Securities  Exchange Act  of 1934, as
amended) that is incorporated by reference in this registration statement  shall
be  deemed to be a new registration statement relating to the securities offered
herein, and the offering of such securities  at that time shall be deemed to  be
the initial bona fide offering thereof.

    Insofar  as indemnification for liabilities under  the Securities Act may be
permitted to  directors,  officers and  controlling  persons of  the  Registrant
pursuant  to  the  provisions described  in  Item  15 above,  or  otherwise, the
Registrant has been advised that in  the opinion of the Securities and  Exchange
Commission  such indemnification  is against public  policy as  expressed in the
Securities Act and is, therefore, unenforceable.  In the event that a claim  for
indemnification  against  such  liabilities  (other  than  the  payment  by  the
Registrant of expenses incurred  or paid by a  director, officer or  controlling
person  of  the Registrant  in the  successful  defense of  any action,  suit or
proceeding) is  asserted by  such  director, officer  or controlling  person  in
connection  with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to  a court  of appropriate  jurisdiction the  question of  whether  such
indemnification  by it is  against public policy as  expressed in the Securities
Act and will be governed by the final adjudication of such issue.

    The undersigned Registrant hereby undertakes that:

        (1) For purposes of determining any liability under the Securities  Act,
    the  information omitted from the  form of prospectus filed  as part of this
    registration statement in reliance upon Rule 430A and contained in a form of
    prospectus filed by  the Registrant  pursuant to  Rule 424(b)(1)  or (4)  or
    497(h)  under  the  Securities  Act  shall be  deemed  to  be  part  of this
    registration statement as of the time it was declared effective.

        (2) For the purpose  of determining any  liability under the  Securities
    Act,  each post-effective amendment that contains a form of prospectus shall
    be deemed to  be a  new registration  statement relating  to the  securities
    offered  therein, and the offering of such  securities at that time shall be
    deemed to be the initial bona fide offering thereof.

                                                                        22062

amount at maturity of its LYONs solely to cover over-allotments.  The aforesaid
$____________ aggregate principal amount at maturity of LYONs (the "Initial
Securities") to be purchased by the Underwriter and all or any part of the
$____________ aggregate principal amount at maturity of the LYONs subject to the
over-allotment option described in Section 2(b) hereof (the "Option Securities")
are collectively referred to herein as the "Securities." The Securities are to
be issued pursuant to an indenture, in substantially the form filed as an
exhibit to the Registration Statement, to be dated as of May __, 1994 (the
"Indenture") between the Company and The Chase Manhattan Bank, N.A., as trustee
(the "Trustee").

          The Securities are convertible into shares of Common Stock, par value
$.01 per share (the "Common Stock"), of the Company at any time before the close
of business on the maturity date of the Securities.  Upon each of the fifth,
tenth and fifteenth anniversaries of the issuance date of the Securities, each
holder of the Securities has the option to require the Company to purchase such
Securities by paying, at the option of the Company, the issue price of the
Securities plus the accrued original issue discount to the date of purchase in
cash or in shares of Common Stock, or in any combination thereof.

          Prior to the purchase and public offering of the Securities by the
Underwriter, the Company and the Underwriter shall enter into an agreement
substantially in the form of Exhibit A hereto (the "Pricing Agreement").  The
Pricing Agreement may take the form of an exchange of any standard form of
written telecommunication between the Company and the Underwriter and shall
specify such applicable information as is indicated in Exhibit A hereto.  The
offering of the Securities will be governed by this Agreement, as supplemented
by the Pricing Agreement.  From and after the date of the execution and delivery
of the Pricing Agreement, this Agreement shall be deemed to incorporate the
Pricing Agreement.

          The Company has filed with the Securities and Exchange Commission (the
"Commission") a registration statement on Form S-3 (No. 33-_____) and a related
preliminary prospectus for the registration of the Securities, and the shares of
Common Stock to be issued upon conversion of the Securities, under the
Securities Act of 1933, as amended  (the "1933 Act"), has filed such amendments
thereto, if any, and such amended preliminary prospectuses as may have been
required to the date hereof, and will file such additional amendments thereto
and such amended prospectuses as may hereafter be required.  Such registration
statement (as amended, if applicable), in the form declared effective by the
Commission, and the prospectus constituting a part thereof (including in each
case all documents, if any, to the extent incorporated or deemed to be
incorporated by reference therein and the information, if any, deemed to be part
of the registration statement pursuant to Rule 430A(b) of the rules and
regulations of the Commission under the 1933 Act (the "1933 Act Regulations")),
as from time to time amended or supplemented pursuant to the 1933 Act, the
Securities Exchange Act of 1934, as amended (the "1934 Act"), or otherwise,


                                                                        22062

are hereinafter referred to as the "Registration Statement" and the
"Prospectus", respectively, except that if any revised prospectus shall be
provided to the Underwriter by the Company for use in connection with the
offering of the Securities which differs from the Prospectus on file at the
Commission at the time the Registration Statement becomes effective (whether or
not such revised prospectus is required to be filed by the Company pursuant to
Rule 424(b) of the 1933 Act Regulations), the term "Prospectus" shall refer to
such revised prospectus from and after the time it is first provided to the
Underwriter for such use.  All references in this Agreement to financial
statements and schedules and other information which is "contained," "included"
or "stated" in the Registration Statement or the Prospectus (and all other
references of like import) shall be deemed to mean and include all such
financial statements and schedules and other information which is incorporated
by reference in, or deemed to be a part of, the Registration Statement or the
Prospectus, as the case may be; and all references in this Agreement to
amendments or supplements to the Registration Statement or the Prospectus shall
be deemed to mean and include the filing of any document under the 1934 Act
after the date of this Agreement which is or is deemed to be incorporated by
reference in the Registration Statement or the Prospectus, as the case may be.

          The Company understands that the Underwriter proposes to make a public
offering of the Securities as soon as the Underwriter deems advisable after the
Registration Statement becomes effective, the Pricing Agreement has been
executed and delivered and the Indenture has been qualified under the Trust
Indenture Act of 1939, as amended (the "1939 Act").

     subsidiaries considered as one enterprise and do not materially interfere
     with the use made and proposed to be made of such properties.

          (xix)     The Company and its subsidiaries possess such material
     certificates, authorities or permits issued by the appropriate state,
     federal or foreign regulatory agencies or bodies necessary to conduct the
     business now operated by them, and neither the Company nor any of its
     subsidiaries has received any notice of proceedings relating to the
     revocation or modification of any such certificate, authority or permit
     which, singly or in the aggregate, if the subject of an unfavorable
     decision, ruling or finding, would materially and adversely affect the
     condition, financial or otherwise, or the earnings or business affairs of
     the Company and its subsidiaries considered as one enterprise.


                                                                        22062

          (xxi)     Except as contemplated by this Agreement, no distribution by
     the Company or any of its affiliates, and no distribution that could be

     (i) pursuant to employee benefit plans and dividend reinvestment plans,
     (ii) upon exercise of currently outstanding warrants or options or (iii)

          (xxii)    This Agreement has been, and, at the Representation Date,
     the Pricing Agreement will have been, duly executed and delivered by the
     Company.

          (b)  Any certificate designated as such signed by any officer of the
Company and delivered to the Underwriter or to counsel for the Underwriter shall

          SECTION 2.  SALE AND DELIVERY TO UNDERWRITER; CLOSING.

          (a)  On the basis of the representations and warranties herein
contained and subject to the terms and conditions herein set forth, the Company
agrees to sell to the Underwriter, and the Underwriter agrees to purchase from
the Company, the Initial Securities at the price per $1,000 principal amount at
maturity set forth in the Pricing Agreement.

          (1)  If the Company has elected not to rely upon Rule 430A under the
     1933 Act Regulations, the initial public offering price, the initial
     conversion rate, the yield to maturity of the Securities, and the purchase
     price (per $1,000 principal amount at maturity) to be paid by the
     Underwriter for the Securities have each been determined and set forth in
     the Pricing Agreement, dated the date hereof, and an amendment to the
     Registration Statement and the Prospectus will be filed before the
     Registration Statement becomes effective.

          (2)  If the Company has elected to rely upon Rule 430A under the 1933
     Act


                                                                        22062

     Regulations, the purchase price (per $1,000 principal amount at maturity)
     to be paid by the Underwriter for the Securities shall be an amount equal
     to the initial public offering price, less an amount per Security to be
     determined by agreement between the Underwriter and the Company.  The
     initial public offering price (per $1,000 principal amount at maturity) of
     the Securities shall be a fixed price to be determined by agreement between
     the Underwriter and the Company.  The initial Conversion Rate applicable to
     the Securities and the yield to maturity of the Securities likewise shall
     be determined by agreement between the Company and the Underwriter.  The
     initial public offering price, initial Conversion Rate, the purchase price
     and yield to maturity, when so determined, shall be set forth in the
     Pricing Agreement.  In the event that such prices, yield and Conversion
     Rate have not been agreed upon and the Pricing Agreement has not been
     executed and delivered by the parties thereto by the close of business on
     the fourth business day following the date of this Agreement, this
     Agreement shall terminate forthwith, without liability of any party to any
     other party, unless otherwise agreed to by the Company and the Underwriter.

          (b)  In addition, on the basis of the representations and warranties
herein contained and subject to the terms and conditions herein set forth, the
Company hereby grants an option to the Underwriter to purchase from it any or
all of the Option Securities (in multiples of $1,000 principal amount at
maturity) at the same price (per $1,000 principal amount at maturity) as is to
be paid by the Underwriter for the Initial Securities on the terms set forth in
the Pricing Agreement, plus accrued Original Issue Discount (as defined in the
Indenture), if any, from the date of issuance of the Initial Securities,
computed on a semi-annual bond-equivalent basis.  The option hereby granted will
expire automatically 30 days after (i) the date the Registration Statement
becomes effective, if the Company has elected not to rely upon Rule 430A under
the 1933 Act Regulations or (ii) the Representation Date, if the Company has
elected to rely upon Rule 430A under the 1933 Act Regulations, and may be
exercised in whole or in part (but only once) only for the purpose of covering
over-allotments which may be made in connection with the offering and
distribution of the Initial Securities upon notice by the Underwriter to the
Company at least three business days prior to the Date of Delivery (as defined
below), or at least two business days prior to the delivery of the Initial
Securities, setting forth the number of Option Securities as to which the
Underwriter is then exercising the option and the time and date of payment and
delivery for such Option Securities.  Any such time and date of delivery (a
"Date of Delivery") shall be determined by the Underwriter but shall not be
later than seven full business days after the exercise of such option, nor in
any event prior to the Closing Time, as hereinafter defined, unless otherwise
agreed by the Underwriter and the Company.

          (c)  Delivery of the Initial Securities shall be made at the offices
of the Underwriter in New York City, and payment of the purchase price for the
Initial Securities shall be made at the offices of Heller, Ehrman, White &

becomes effective (or, if the Company has elected to rely upon Rule 430A, the
fifth business day after execution of the Pricing Agreement), or such other time
not later than ten business days after such date as shall be agreed upon by the
Underwriter and the Company (such time and date of payment and delivery being
herein called the "Closing Time").  In addition, in the event that any or all of
the Option Securities are purchased by the Underwriter, payment of the purchase
price for, and delivery of certificates for, such Option Securities shall be
made at the above-mentioned offices of Heller, Ehrman, White & McAuliffe and the
Underwriter, respectively, or at such other place as shall be agreed upon by the
Underwriter and the Company, on the Date of Delivery as specified in the notice

Certificates evidencing the Initial Securities and the Option Securities, if
any, shall be registered in such names and in such denominations as the
Underwriter may request in writing at least two business days before the Closing
Time or the Date of Delivery, as the case may be.  The certificates for the
Initial Securities or the Option Securities, if any, will be made available for
examination and packaging by the Underwriter not later than 10:00 A.M. (New York
City time), on the last business day prior to the Closing Time or the  Date of

with the Underwriter as follows:

          (a)  The Company will notify the Underwriter immediately, and confirm
     the notice in writing, (i) of the effectiveness of the Registration
     Statement and any amendment thereto (including any post-effective
     amendment) and, if Rule 430A of the 1933 Act Regulations is being relied
     upon, of the filing of the amended Prospectus pursuant to Rule 430A and
     Rule 424(b)(1), (ii) of the receipt of any comments from the Commission,
     (iii) of any request by the Commission for any amendment to the
     Registration Statement or any amendment or supplement to the Prospectus or
     for additional information, and (iv) of the issuance by the Commission of
     any stop order suspending the effectiveness of the Registration Statement
     or the initiation of any proceedings for that purpose.  The Company will
     make every reasonable effort to prevent the issuance of any stop order and,
     if any stop order is issued, to obtain the lifting thereof at the earliest
     possible moment.

          (b)  The Company will not at any time file or make any amendment to
     the Registration Statement (including any post-effective amendment) or any
     amendment or


                                                                        22062

<PAGE>

                                       12

     supplement to the Prospectus (including any revised prospectus which the
     Company proposes for use by the Underwriter in connection with the offering
     of the Securities which differs from the prospectus on file at the
     Commission at the time the Registration Statement becomes effective,
     whether or not such revised prospectus is required to be filed pursuant to
     Rule 424(b) of the 1933 Act Regulations), whether pursuant to the 1933 Act,
     the 1934 Act or otherwise, of which the Underwriter shall not have
     previously been advised and furnished a copy a reasonable amount of time
     prior to its proposed filing, or to which the Underwriter or counsel for
     the Underwriter shall reasonably object.

          (c)  The Company will deliver to the Underwriter two signed copies of
     the Registration Statement as originally filed and of each amendment
     thereto (including exhibits filed therewith or incorporated by reference
     therein and documents incorporated or deemed incorporated by reference
     therein) as the Underwriter may reasonably request and will also deliver to
     the Underwriter as many conformed copies of the Registration Statement as
     originally filed and of each amendment thereto (without exhibits) as the
     Underwriter may reasonably request.

          (d)  The Company will furnish to the Underwriter, from time to time
     during the period when the Prospectus is required to be delivered under the
     1933 Act or the 1934 Act, such number of copies of the Prospectus (as
     amended or supplemented) as the Underwriter may reasonably request for the
     purposes contemplated by the 1933 Act or the 1934 Act or the respective
     applicable rules and regulations of the Commission thereunder.

          (e)  If any event shall occur or condition exist as a result of which
     it is necessary, in the opinion of counsel for the Underwriter or counsel
     for the Company, to amend the Registration Statement or amend or supplement
     the Prospectus in order that the Prospectus will not include an untrue
     statement of a material fact or omit to state a material fact necessary in
     order to make the statements therein not misleading in the light of the
     circumstances existing at the time it is delivered to a purchaser, the
     Company will promptly prepare and file with the Commission, subject to
     Section 3(b) hereof, such amendment or supplement as may be necessary to
     correct such untrue statement or omission, and the Company will furnish to
     the Underwriter a reasonable number of copies of such amendment or
     supplement.  The Company agrees to notify the Underwriter to suspend use of
     the Prospectus as promptly as practicable after the occurrence of such an
     event or the existence of such a condition, and the Underwriter hereby
     agrees to suspend use of the Prospectus until the Company has amended or
     supplemented the Prospectus to correct such misstatement or omission.

          (f)  The Company will use its best efforts, in cooperation with the


                                                                        22062

     United States as the Underwriter may designate; provided, however, that the
     Company shall not be obligated to qualify as a foreign corporation in any
     jurisdiction in which it is not so qualified.  In each jurisdiction in
     which the Securities or such shares of Common Stock have been so qualified,
     the Company will file such statements and reports as may be required by the
     laws of such jurisdiction to continue such qualification in effect for so

          (i)  If, at the time that the Registration Statement becomes
     effective, any information shall have been omitted therefrom in reliance
     upon Rule 430A of the 1933 Act Regulations, then immediately following the
     execution of the Pricing Agreement, the Company will prepare, and file or
     transmit for filing with the Commission in accordance with such Rule 430A
     and Rule 424(b) of the 1933 Act Regulations, copies of an amended
     Prospectus, or, if required by such Rule 430A, a post-effective amendment
     to the Registration Statement (including an amended Prospectus), containing
     all information so omitted.

          (j)  The Company, during the period when the Prospectus is required to
     be delivered under the 1933 Act or the 1934 Act, will file all documents
     required to be filed with the Commission pursuant to Section 13, 14 or 15
     of the 1934 Act within the time periods required by the 1934 Act and the
     1934 Act Regulations of which the Underwriter shall have previously been
     advised and furnished a copy, and to which the Underwriter or its counsel
     shall not have reasonably objected.

          (k)  For a period of five years after the Closing Time, the Company
     will furnish to the Underwriter copies of all reports and communications
     delivered to the Company's stockholders or to holders of the Securities as

     Q and 10-K, and all other reports and information furnished to its
     stockholders generally, not later than the time such reports are first
     furnished to its stockholders generally.

          (l)  The Company will use its best efforts to effect the listing of
     the Securities and the shares of Common Stock issuable upon conversion or
     purchase of the Securities on the New York Stock Exchange (the "NYSE")
     (and, in the case of such shares of the Common Stock, any other stock
     exchange on which the Common Stock is listed) and to cause the Securities
     to be registered under the 1934 Act.

          (m)  The Company will reserve and keep available at all times, free of
     preemptive rights, sufficient shares of Common Stock for issuance upon
     conversion of all the Securities.

     business in Cuba.

          (o)  During a period of 90 days from the date of the Pricing
     Agreement, the Company will not, without the Underwriter's prior written
     consent, directly or indirectly, sell, offer to sell, grant any option for
     the sale of, or otherwise dispose of or transfer, any securities similar to
     the Securities or any Common Stock or any security convertible into or
     exchangeable or exercisable for any Securities or any such similar
     securities or Common Stock except for securities (i) sold to the
     Underwriter pursuant to this Agreement, (ii) issued or sold pursuant to
     employee benefit plans and dividend reinvestment plans, (iii) issued upon
     exercise of currently outstanding warrants or options, or (iv) issued or
     sold in a transaction exempt from the registration requirements of the 1933
     Act; PROVIDED, HOWEVER, that in the case of clause (iv), such securities
     may not (A) exceed, or be convertible into or exchangeable or exercisable
     for more than, fifteen percent (15%) of the fully diluted equity interest
     in the company and (B) be eligible for the PORTAL trading system of the
     National Association of Securities Dealers, Inc.

                    (v)  Assuming the due authorization, execution and delivery
               thereof by the Trustee, the Indenture is a valid and binding
               obligation of the Company enforceable against the Company in

               specified herein and in the Pricing Agreement, will constitute
               valid and binding obligations of the Company, enforceable against
               the Company in accordance with their terms, subject as to
               enforcement (i) to bankruptcy, insolvency, reorganization,
               arrangement, moratorium, fraudulent conveyance and other laws of
               general applicability relating to or affecting creditors' rights
               and (ii) to general principles of equity, whether such
               enforcement is considered in a proceeding in equity or at law
               and, except as set forth above, will be entitled to the benefits
               of the Indenture; and the issuance of the Securities is not
               subject to any preemptive rights or other rights of first refusal
               arising by operation of law or under the Certificate of
               Incorporation or bylaws of the Company.

                    (vii)     The shares of Common Stock issuable upon
               conversion of the Securities at the initial Conversion Rate (as
               defined in the Indenture) have been duly authorized and validly
               reserved by the Company for issuance upon such conversion and,
               when issued and delivered upon such conversion in the manner
               provided in the Indenture, will be validly issued, fully paid and
               nonassessable; and the issuance of such shares upon such
               conversion is not presently subject to any preemptive rights or
               other rights of first refusal arising by operation of law or
               under the Certificate of Incorporation or bylaws of the Company.

                    (ix) This Agreement and the Pricing Agreement have been duly
               authorized by all necessary corporate action on the part of the
               Company and have been duly executed and delivered on behalf of
               the Company.

                    (x)  The Securities, the Common Stock and the Indenture

               the 1933 Act or proceedings therefor initiated or threatened by
               the Commission.

                    (xiii)    At the time the Registration Statement became
               effective and at the Representation Date, the Registration
               Statement (other than the financial statements and supporting
               schedules included therein, as to which no opinion need be
               rendered) complied as to form in all material respects with the
               requirements of the 1933 Act and the 1933 Act Regulations.

               captions "Description of LYONs," other than the information in
               the last paragraph under the heading "Conversion Rights," to the
               extent that it constitutes matters of law, summaries of legal
               matters, documents or proceedings, or legal conclusions, has been
               reviewed by such counsel and is correct in all material respects.

                    (xv) No government consents, approvals, authorizations,
               registrations, declarations or filings, or order of any court of

               the offering, issuance or sale of the Securities to the
               Underwriter, except such as may be required under the 1933 Act,
               the 1933 Act Regulations, the 1934 Act, the 1934 Act Regulations,
               the 1939 Act, the 1939 Act Regulations or state securities laws
               for the offering and sale of the Securities and the qualification
               of the Indenture under the 1939 Act.

                    (xvi)     Neither the execution and delivery of this
               Agreement, the Pricing Agreement or the Indenture by the Company
               nor the performance of this Agreement, the Pricing Agreement or
               the Indenture by the Company (A) conflicts with any provision of
               the Certificate of Incorporation or bylaws of the Company or (B)
               violates any law applicable to the Company.

                    (xvii)    Neither the issuance and delivery of the
               Securities or the Common Stock issuable upon conversion of the
               Securities nor the purchase of the Securities by the Company
               (A) conflicts with any provision of the Certificate of
               Incorporation or bylaws of the Company or (B) violates any law
               applicable to the Company.

               The opinion expressed in subsection (xv) of this Section 5(b)(1)

          rendered as to, federal or state securities laws, patent laws or

          subsection (b)(1) of this Section, Heller, Ehrman, White & McAuliffe
          shall additionally state that nothing has come to their attention that
          would lead them to believe (A) that the Registration Statement or any
          amendment thereto  (other than the financial statements and supporting
          schedules and other financial data included therein, and other than
          the information contained under the caption "Certain United States
          Federal Income Tax Considerations" in the Registration Statement, as
          to which no belief need be expressed), at the time the Registration
          Statement or any such amendment became effective, contained an untrue
          statement of a material fact or omitted or omits to state a material
          fact required to be stated therein or necessary in order to make the
          statements therein not misleading or that (B) that the Prospectus or
          any amendment or supplement thereto (other than the financial
          statements and supporting schedules and other financial data included
          therein, and other than the information contained under the caption
          "Certain United States Federal Income Tax Considerations" in the
          Prospectus, as to which no belief need be expressed), at the
          Representation Date (unless the term "Prospectus" refers to a
          prospectus which has been provided to the Underwriter by the Company
          for use in connection with the offering of the Securities which
          differs from the Prospectus on file at the Commission at the time the
          Registration Statement becomes effective, in which case at the time it
          is first provided to the Underwriter for such use) or at the Closing
          Time, contained or contains an untrue statement of a material fact or
          omitted or omits to state a material fact necessary in order to make
          the statements therein, in the light of the circumstances under which
          they were made, not misleading.

               (2)  A signed opinion of Peter D. Staple, Esq., Vice President
          and General Counsel of the Company, dated as of the Closing Time, in
          form and substance satisfactory to counsel for the Underwriter, to the
          effect that:

                    (i)  To the knowledge of such counsel, the Company is duly
               qualified as a foreign corporation to transact business and is in
               good standing in each jurisdiction in which such qualification is
               required, whether by reason of the ownership or leasing of
               property or the conduct of business, except where the failure to
               so qualify would not have a material adverse effect on the
               condition, financial or otherwise,


                                                                        22062

               plans or issued upon exercise of currently outstanding warrants
               or options, in each case as the same may be referred to in the
               Prospectus), and the shares of issued and outstanding Common
               Stock have been duly authorized and validly issued and are fully
               paid and non-assessable.

                    (iii)     Each subsidiary of the Company has been duly

               has corporate power and authority to own, lease and operate its
               properties and to conduct its business as described in the

               a foreign corporation to transact business and is in good
               standing in each jurisdiction in which such qualification is
               required, whether by reason of the ownership or leasing of
               property or the conduct of business, except where the failure to
               so qualify would not have a material adverse effect on the
               condition, financial or otherwise, or the earnings or business
               affairs of the Company and its subsidiaries considered as one
               enterprise; all of the issued and outstanding capital stock of
               each such subsidiary has been duly authorized and validly issued,
               is fully paid and non-assessable and, to such counsel's
               knowledge, is owned by the Company, directly or through
               subsidiaries, free and clear of any security interest, mortgage,
               pledge, lien, encumbrance, claim or equity.

                    (iv) The information in the Company's Annual Report on Form
               10-K filed with the Commission pursuant to the 1934 Act for the
               year ended December 31, 1993 under the caption "Item 3. Legal
               Proceedings", as supplemented by the information in the Company's
               Quarterly Report on Form 10-Q filed with the Commission pursuant

               caption "Part II: Other Information - Item 1.  Legal
               Proceedings," to the extent that it constitutes matters of law,
               summaries of legal documents or proceedings, or legal

               of its subsidiaries, (B) violate any law, administrative
               regulation or administrative or court decree applicable to the

               to which any of the properties or assets of the Company are
               subject.

     E & Y Letter"), in form and substance satisfactory to the Underwriter.

          (e)  At the Closing Time, the Underwriter shall have received from
     Ernst & Young a letter, dated as of the Closing Time, confirming, on the
     basis of a review in accordance with the procedures set forth in the First
     E & Y Letter, that nothing has come to their attention from the date of the
     most recent financial statements of the Company filed with the Commission,
     audited or interim, as the case may be, to a date not more than five days
     prior to the Closing Time which would require any change in the First E & Y
     Letter if it were required to be dated and delivered at the Closing Time,
     except in each case as described in the second such letter.

          (f)  Subsequent to the execution of this Agreement, no downgrading
     shall have occurred in the rating accorded any of the Company's debt
     securities by


                                                                        22062

     Standard & Poor's Corporation or Moody's Investors Service, and neither
     such organization shall have publicly announced that it has under
     surveillance or review, with possible negative implications, its rating
     accorded any of the Company's debt securities, if in the reasonable
     judgment of the Underwriter any such development is so material and adverse
     as to make it impracticable or inadvisable to consummate the sale and
     delivery of the Securities by the Underwriter as contemplated in the
     Prospectus.

          (g)  At the Closing Time, the Securities and the Common Stock issuable
     upon conversion thereof shall have been approved for listing on the NYSE
     upon notice of issuance.

          (h)  At the Closing Time, and at the Date of Delivery, if any, counsel
     for the Underwriter shall have been furnished with such documents and
     opinions as they may reasonably require for the purpose of enabling them to
     pass upon the issuance and sale of the Securities as herein contemplated
     and related proceedings, or in order to evidence the accuracy of any of the
     representations or warranties, or the fulfillment of any of the conditions,
     herein contained; and all proceedings taken by the Company in connection
     with the issuance and sale of the Securities as herein contemplated shall
     be satisfactory in form and substance to the Underwriter and counsel for
     the Underwriter.

          (i)  In the event that the Underwriter exercises its option provided
     in Section 2(b) hereof to purchase all or any portion of the Option
     Securities and the Date of Delivery is not the same as the Closing Time,
     the representations and warranties of the Company contained herein and the
     statements in any certificates furnished by the Company hereunder shall be
     true and correct as of the Date of Delivery, and, at the Date of Delivery,
     the Underwriter shall have received:

               (1)  A certificate, dated the Date of Delivery, of the President
          or a Vice President of the Company and the chief financial or chief
          accounting officer of the Company confirming that the certificate
          delivered at the Closing Time pursuant to Section 5(c) hereof remains
          true and correct as of the Date of Delivery.

               (2)  The favorable opinion of Heller, Ehrman, White & McAuliffe,
          counsel to the Company, in form and substance satisfactory to counsel
          for the Underwriter, dated the Date of Delivery, relating to the
          Option Securities to be purchased on the Date of Delivery and
          otherwise to the same effect as the opinion required by Section
          5(b)(1) hereof.


                                                                        22062

               (3) The favorable opinion of Peter D. Staple, Esq., Vice
          President and General Counsel of the Company, in form and substance
          satisfactory to counsel for the Underwriter, dated the Date of
          Delivery, and to the same effect as the opinion required by Section
          5(b)(2) hereof.

               (4)  The favorable opinion of Shearman & Sterling, counsel for
          the Underwriter, dated the Date of Delivery, relating to the Option
          Securities to be purchased on the Date of Delivery and otherwise to
          the same effect as the opinion required by Section 5(b)(3) hereof.

               (5)  The favorable opinions of Mayer, Brown & Platt, special
          counsel to the Underwriter and special tax counsel to the Company,
          dated the Date of Delivery, to the same effect as the opinion required
          by Section 5(b)(4) hereof.

               (6)  A letter from Ernst & Young, in form and substance
          satisfactory to the Underwriter and dated the Date of Delivery,
          substantially the same in form and substance as the letter furnished
          to the Underwriter pursuant to Section 5(e) hereof, except that the
          "specified date" in the letter furnished pursuant to this Section
          5(i)(6) shall be a date not more than five days prior to the Date of
          Delivery.

          If any of the conditions specified in this Section shall not have been
fulfilled when and as required to be fulfilled, this Agreement may be terminated
by the Underwriter by notice to the Company at any time at or prior to the
Closing Time, and such termination shall be without liability of any party to
any other party except as provided in Section 4 hereof, and provided further
that Sections 6 and 7 hereof shall survive such termination.

          SECTION 6.  INDEMNIFICATION.

          (a)  The Company agrees to indemnify and hold harmless the Underwriter
and each person, if any, who controls the Underwriter within the meaning of
Section 15 of the 1933 Act as follows:

          (i)  against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, arising out of any untrue statement or alleged
     untrue statement of a material fact contained in the Registration Statement
     (or any amendment thereto), including the information deemed to be part of
     the Registration Statement pursuant to Rule 430A(b) of the 1933 Act
     Regulations, if applicable, and all documents incorporated therein by
     reference, or the omission or alleged omission therefrom of a material fact
     required to be stated therein or necessary to make the


                                                                        22062

<PAGE>

                                       26

     statements therein not misleading or arising out of any untrue statement or
     alleged untrue statement of a material fact contained in any preliminary
     prospectus or the Prospectus (or any amendment or supplement thereto) or
     the omission or alleged omission therefrom of a material fact necessary in
     order to make the statements therein, in the light of the circumstances
     under which they were made, not misleading;

          (ii) against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, to the extent of the aggregate amount paid in
     settlement of any litigation, or any investigation or proceeding by any
     governmental agency or body, commenced or threatened, or of any claim
     whatsoever based, in each case, upon any such untrue statement or omission,
     or any such alleged untrue statement or omission, if such settlement is
     effected with the written consent of the Company; and

          (iii)     against any and all expense whatsoever, as incurred
     (including, subject to Section 6(c) hereof, the fees and disbursements of
     counsel chosen by the Underwriter), reasonably incurred in investigating,
     preparing or defending against any litigation, or any investigation or
     proceeding by any governmental agency or body, commenced or threatened, or
     any claim whatsoever based, in each case, upon any such untrue statement or
     omission, or any such alleged untrue statement or omission, to the extent
     that any such expense is not paid under (i) or (ii) above;

PROVIDED, HOWEVER, that this indemnity agreement shall not apply to any loss,
liability, claim, damage or expense to the extent arising out of any untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished to the Company by the
Underwriter, or any person controlling the Underwriter, expressly for use in the
Registration Statement (or any amendment thereto) or any preliminary prospectus
or the Prospectus (or any amendment or supplement thereto); and PROVIDED,
FURTHER, that the Company shall not be liable to the Underwriter under the
indemnity agreement in this subsection (a) with respect to any preliminary
prospectus to the extent that any such loss, liability, claim, damage or expense
of the Underwriter results from the fact that the Underwriter sold Securities to
a person to whom there was not sent or given, at or prior to the written
confirmation of such sale, a copy of the Prospectus as then amended or
supplemented (excluding documents incorporated by reference therein) in any case
where such delivery is required by the 1933 Act if the Company has previously
furnished copies thereof to the Underwriter and the loss, liability, claim,
damage or expense of the Underwriter results from an untrue statement or
omission or alleged untrue statement or omission of a material fact contained in
the preliminary prospectus which was corrected in the Prospectus (or the
Prospectus as amended or supplemented).

          (b)  The Underwriter agrees to indemnify and hold harmless the
Company,


                                                                        22062

<PAGE>

                                       27

its directors, each of its officers who signed the Registration Statement, and
each person, if any, who controls the Company within the meaning of Section 15
of the 1933 Act, against any and all loss, liability, claim, damage and expense
described in the indemnity contained in subsection (a) of this Section, as
incurred, but only with respect to untrue statements or omissions, or alleged
untrue statements or omissions, made in the Registration Statement (or any
amendment thereto) or any preliminary prospectus or the Prospectus (or any
amendment or supplement thereto) in reliance upon and in conformity with written
information furnished to the Company by the Underwriter expressly for use in the
Registration Statement (or any amendment thereto) or such preliminary prospectus
or the Prospectus (or any amendment or supplement thereto).

          (c)  Each indemnified party shall give notice as promptly as
reasonably practicable to each indemnifying party of any action commenced
against it in respect of which indemnity may be sought hereunder, but failure to
so notify an indemnifying party shall not relieve such indemnifying party from
any liability which it may have otherwise than on account of this indemnity
agreement.  An indemnifying party may participate at its own expense in the
defense of any such action.  If it so elects within a reasonable time after
receipt of such notice, an indemnifying party, jointly with any other
indemnifying parties receiving such notice, may assume the defense of such
action with counsel chosen by it and approved by the indemnified parties
defendant in such action, provided that, if such indemnified party or parties
reasonably determine that there may be legal defenses available to them which
are different from or in  addition to those available to such indemnifying party
or parties, then such indemnifying party or parties shall not be entitled to
assume such defense.  If the indemnifying party or parties are not entitled to
assume the defense of such action as a result of the proviso to the preceding
sentence, counsel for the indemnifying party or parties shall be entitled to
conduct the defense of such indemnifying party or parties and counsel for the
indemnified party or parties shall be entitled to conduct the defense of such
indemnified party or parties.  If an indemnifying party is entitled to so assume
the defense of such action and does in fact assume the defense of such action,
the indemnifying parties shall not be liable for any fees and expenses of
counsel for the indemnified parties incurred thereafter in connection with such
action.  In no event shall the indemnifying parties be liable for fees and
expenses of more than one counsel (in addition to any local counsel) separate
from their own counsel for all indemnified parties in connection with any one
action or separate but similar or related actions in the same jurisdiction
arising out of the same general allegations or circumstances.

          SECTION 7.  CONTRIBUTION.  In order to provide for just and equitable
contribution in circumstances in which the indemnity agreement provided for in
Section 6 hereof is for any reason held to be unenforceable by the indemnified
parties although applicable in accordance with its terms, the Company and the
Underwriter shall contribute to the aggregate losses, liabilities, claims,
damages and expenses of the nature contemplated by


                                                                        22062

                                       28

said indemnity agreement incurred by the Company and the Underwriter, as
incurred, in such proportions that the Underwriter is responsible for that
portion represented by the percentage that the underwriting discount appearing
on the cover page of the Prospectus bears to the initial public offering price
appearing thereon and the Company is responsible for the balance; provided,
however, that no person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation.  For
purposes of this Section, each person, if any, who controls the Underwriter
within the meaning of Section 15 of the 1933 Act shall have the same rights to
contribution as the Underwriter, and each director of the Company, each officer
of the Company who signed the Registration Statement, and each person, if any,
who controls the Company within the meaning of Section 15 of the 1933 Act shall
have the same rights to contribution as the Company.

          SECTION 8.  CONDITION OF COMPANY'S OBLIGATION.  The obligations of the
Company hereunder are subject to the condition that the Company shall have
received the favorable opinion, dated as of the Closing Time, of Mayer, Brown &
Platt, special tax counsel to the Company, to the effect that (i) the opinion of
such counsel set forth in the Prospectus under the caption "Certain United
States Federal Income Tax Considerations" is confirmed and (ii) the information
in the Prospectus under the caption "Certain United States Federal Income Tax
Considerations", while not purporting to discuss all tax matters relating to the
Securities, to the extent that it constitutes a summary of federal income tax
matters relating to the Securities, is correct in all material respects.

          SECTION 9.  REPRESENTATIONS, WARRANTIES AND AGREEMENTS TO SURVIVE
DELIVERY.  The representations, warranties, indemnities, agreements and other
statements of the Company or its officers set forth in this Agreement and the
Pricing Agreement, or contained in certificates of officers of the Company
submitted pursuant hereto, shall remain operative and in full force and effect,
regardless of any investigation made by or on behalf of the Underwriter or
controlling person, or by or on behalf of the Company, and shall survive
delivery of the Securities to, and payment for the Securities by, the
Underwriter.  The indemnities of the Underwriter set forth in this Agreement and
the Pricing Agreement shall remain operative and in full force and effect
regardless of any investigation made by or on behalf of the Company, its
directors, officers or controlling persons, or by or on behalf of the
Underwriter, and shall survive delivery of the Securities by, and payment for
the Securities to, the Company.

          SECTION 10.  TERMINATION OF AGREEMENT.

          (a)  The Underwriter may terminate this Agreement, by notice to the
Company, at any time at or prior to the Closing Time (i) if there has been,
since the date of this Agreement or since the respective dates as of which
information is given in the


                                                                        22062

Registration Statement, any material adverse change in the condition,
financial or otherwise, or in the earnings or business affairs of the Company
and its subsidiaries considered as one enterprise, whether or not arising in the
ordinary course of business, or (ii) if there has occurred any material adverse
change in the financial markets in the United States or any outbreak of
hostilities or escalation thereof, or other calamity or crisis the effect of
which is such as to make it, in the judgment of the Underwriter, impracticable
to market the Securities or to enforce contracts for the sale of the Securities,
or (iii) if trading in the Common Stock has been suspended by the Commission, or
if trading generally on either the American Stock Exchange or the New York Stock
Exchange has been suspended, or minimum or maximum prices for trading have been
fixed, or maximum ranges for prices for securities have been required, by either
of said Exchanges or by order of the Commission or any other governmental
authority, or if a banking moratorium has been declared by either Federal, New
York or California authorities.

          (b)  If this Agreement is terminated pursuant to this Section, such
termination shall be without liability of any party to any other party except as
provided in Section 4 hereof, and provided further that Sections 6, 7 and 9
hereof shall survive such termination.

          SECTION 11.  NOTICES.  All notices and other communications hereunder
shall be in writing and shall be deemed to have been duly given if mailed or
transmitted by any standard form of telecommunication.  Notices to the
Underwriter shall be directed to it at 101 California Street, San Francisco,

California  94301, Attention:  Sarah A. O'Dowd.

          SECTION 12.  PARTIES.  This Agreement and the Pricing Agreement are
made solely for the benefit of the Company and the Underwriter, and, to the
extent expressed, any person controlling the Company or the Underwriter within
the meaning of Section 15 of the 1933 Act, and the directors of the Company and
its officers who have signed the Registration Statement, and their respective
executors, administrators, successors and assigns, and no other person shall
acquire or have any right under or by virtue of this Agreement.  The term
"successors and assigns" shall not include any purchaser, as such purchaser, of
Securities from the Underwriter.

          SECTION 13.  GOVERNING LAW AND TIME.  This Agreement and the Pricing
Agreement shall be governed by and construed in accordance with the laws of the
State of New York applicable to agreements made and to be performed in said
State.  Unless otherwise set forth herein, specified times of day refer to New
York City time.


                                                                        22062

                                       30


          SECTION 14.  AMENDMENTS.  No amendment or waiver of any provision of
this Agreement, nor any consent or approval to any departure therefrom, shall in
any event be effective unless the same shall be in writing and signed by the
parties hereto.

          SECTION 15.  COUNTERPARTS.  This Agreement may be executed in one or
more counterparts and when a counterpart has been executed by each party, all
such counterparts taken together shall constitute one and the same agreement.


                                                                        22062

agreement, please sign and return to the Company a counterpart hereof, whereupon

          Trustee's certificate of authentication shall be substantially in
          the form of Exhibit A, which is a part of this Indenture.  The
          Securities may have notations, legends or endorsements required
          by law, stock exchange rule or usage (provided that any such
          notation, legend or endorsement required by usage is in a form
          acceptable to the Company and the Trustee).  Each Security shall
          be dated the date of its authentication.

               SECTION 2.2.   EXECUTION AND AUTHENTICATION.  The Securities
          shall be executed by the Company by either of its Co-Chairmen of
          the Board, its President or one of its Vice Presidents, under its
          corporate seal reproduced thereon attested by its Secretary or
          one of its Assistant Secretaries.  The signature of any of these
          officers on the Securities may be manual or facsimile.

               Securities bearing the manual or facsimile signatures of
          individuals who were at any time the proper Officers of the


                                      6

<PAGE>

          Company shall bind the Company, notwithstanding that such
          individuals or any of them have ceased to hold such offices prior
          to the authentication and delivery of such Securities or did not
          hold such offices at the Issue Date of such Securities.

               No Security shall be entitled to any benefit under this
          Indenture or be valid or obligatory for any purpose unless there
          appears on such Security a certificate of authentication
          substantially in the form provided for herein duly executed by
          the Trustee by manual signature of an authorized signatory, and
          such certificate upon any Security shall be conclusive evidence,
          and the only evidence, that such Security has been duly
          authenticated and delivered hereunder.

               The Trustee shall authenticate and make available for
          delivery Securities for original issue in an aggregate Principal
          Amount of up to $___,000,000 upon a Company Order without any
          further action by the Company; PROVIDED, HOWEVER, that in the
          event that the Company sells any Securities pursuant to the over-
          allotment option (the "OVER-ALLOTMENT OPTION") granted pursuant
          to Section 2 of the Purchase Agreement, dated _______________,
          1994, between the Company and Merrill Lynch & Co., Merrill Lynch,
          Pierce, Fenner & Smith Incorporated, then the Trustee shall
          authenticate and deliver Securities for original issue in an
          aggregate Principal Amount of up to $___,000,000 plus up to
          $___,___,000 aggregate Principal Amount of Securities sold
          pursuant to the Over-allotment Option upon a Company Order
          without any further action by the Company.  The aggregate
          Principal Amount of Securities outstanding at any time may not
          exceed the amount set forth in the foregoing sentence, subject to
          the proviso set forth therein, except as provided in Section 2.7.

               SECTION 2.3.   REGISTRAR, PAYING AGENT AND CONVERSION AGENT.
          The Company shall maintain an office or agency where Securities
          may be presented for registration of transfer or for exchange
          ("Registrar"), an office or agency where Securities may be
          presented for purchase or payment ("PAYING AGENT") and an office
          or agency where Securities may be presented for conversion
          ("CONVERSION AGENT").  The Registrar shall keep a register of the
          Securities and of their transfer and exchange.  The Company may
          have one or more co-registrars, one or more additional paying
          agents and one or more additional conversion agents.  The term
          Paying Agent includes any additional paying agent.  The term
          Conversion Agent includes any additional conversion agent.

               The Company shall enter into an appropriate agency agreement
          with any Registrar, Paying Agent, Conversion Agent or co-
          registrar (with the consent of the Trustee) other than the
          Trustee.  The agreement shall implement the provisions of this
          Indenture that relate to such agent.  The Company shall notify
          the Trustee and the Holders of the name and address of any such


                                      7

<PAGE>

          agent and of any change in the office or agency referred to in
          Section 4.5.  If the Company fails to maintain a Registrar,
          Paying Agent or Conversion Agent, the Trustee shall act as such
          and shall be entitled to appropriate compensation therefor
          pursuant to Section 7.7.  The Company or any Subsidiary or an
          Affiliate of either of them may act as Paying Agent, Registrar,
          Conversion Agent or co-registrar.

               The Company initially appoints the Trustee as Registrar,
          Conversion Agent and Paying Agent in connection with the
          Securities.

               SECTION 2.4.   PAYING AGENT TO HOLD MONEY AND SECURITIES IN
          TRUST.  Except as otherwise provided herein, prior to or on
          each due date of payments in respect of any Security, the Company
          shall deposit with the Paying Agent a sum of money or, if
          permitted by the terms hereof, securities sufficient to make such
          payments when so becoming due.  The Company shall require each
          Paying Agent (other than the Trustee) to agree in writing that
          the Paying Agent shall hold in trust for the benefit of
          Securityholders or the Trustee all money and securities held by
          the Paying Agent for the making of payments in respect of the
          Securities and shall notify the Trustee of any default by the
          Company in making any such payment.  At any time during the
          continuance of any such default, the Paying Agent shall, upon the
          written request of the Trustee, forthwith pay to the Trustee all
          money and securities so held in trust.  If the Company, a
          Subsidiary or an Affiliate of either of them acts as Paying
          Agent, it shall segregate the money and securities held by it as
          Paying Agent and hold it as a separate trust fund.  The Company
          at any time may require a Paying Agent to pay all money and
          securities held by it to the Trustee and to account for any money
          and securities disbursed by it.  Upon doing so, the Paying Agent
          shall have no further liability for the money and securities.

               SECTION 2.5.   SECURITYHOLDER LISTS.  The Trustee shall
          preserve in as current a form as is reasonably practicable the
          most recent list available to it of the names and addresses of
          Securityholders.  If the Trustee is not the Registrar, the
          Company shall furnish or cause to be furnished to the Trustee (i)
          at least semiannually on January 1 and July 1 a list of the names
          and addresses of Securityholders dated within 15 days of the date
          on which the list is furnished and (ii) at such other times as
          the Trustee may request in writing a list, in such form and as of
          such date as the Trustee may reasonably require, of the names and
          addresses of Securityholders.

               SECTION 2.6.   TRANSFER AND EXCHANGE.  Upon surrender for
          registration of transfer of any Security, together with a written
          instrument of transfer satisfactory to the Registrar duly
          executed by the Securityholder or such Securityholder's attorney


                                      8

<PAGE>

          duly authorized in writing, at the office or agency of the
          Company designated as Registrar or co-registrar pursuant to
          Section 2.3 or at the office or agency referred to in Section
          4.5, the Company shall execute, and the Trustee shall
          authenticate and deliver, in the name of the designated
          transferee or transferees, one or more new Securities of any
          authorized denomination or denominations, of a like aggregate
          Principal Amount.  The Company shall not charge a service charge
          for any registration of transfer or exchange, but the Company may
          require payment of a sum sufficient to pay all taxes, assessments
          or other governmental charges that may be imposed in connection
          with the transfer or exchange of the Securities from the
          Securityholder requesting such transfer or exchange (other than
          any exchange of a temporary Security for a definitive Security
          not involving any change in ownership).

               At the option of the Holder, Securities may be exchanged for
          other Securities of any authorized denomination or denominations,
          of a like aggregate Principal Amount, upon surrender of the
          Securities to be exchanged, together with a written instrument of
          transfer satisfactory to the Registrar duly executed by the
          Securityholder or such Securityholder's attorney duly authorized
          in writing, at such office or agency.  Whenever any Securities
          are so surrendered for exchange, the Company shall execute, and
          the Trustee shall authenticate and deliver, the Securities which
          the Holder making the exchange is entitled to receive.

               The Company shall not be required to make, and the Registrar
          need not register, transfers or exchanges of (a) Securities
          selected for redemption (except, in the case of Securities to be
          redeemed in part, the portion thereof not to be redeemed), (b)
          any Securities in respect of which a Purchase Notice or a Change
          in Control Purchase Notice has been given and not withdrawn by
          the Holder thereof in accordance with the terms of this Indenture
          (except, in the case of Securities to be purchased in part, the
          portion thereof not to be purchased) or (c) any Securities for a
          period of 15 days before a selection of Securities to be
          redeemed.

               SECTION 2.7.   REPLACEMENT SECURITIES.  If (a) any mutilated
          Security is surrendered to the Company or the Trustee, or (b) the
          Company and the Trustee receive evidence to their satisfaction of
          the destruction, loss or theft of any Security, and there is
          delivered to the Company and the Trustee such security or
          indemnity as may be required by them to save each of them
          harmless, then, in the absence of notice to the Company or the
          Trustee that such Security has been acquired by a bona fide
          purchaser, the Company shall execute, and upon its written
          request the Trustee shall authenticate and deliver, in exchange
          for any such mutilated Security or in lieu of any such destroyed,
          lost or stolen Security, a new Security of like tenor and


                                      9


<PAGE>

          Principal Amount, bearing a number not contemporaneously
          outstanding.

               In case any such mutilated, destroyed, lost or stolen
          Security has become or is about to become due and payable, or is
          about to be purchased by the Company pursuant to Article 3
          hereof, the Company in its discretion may, instead of issuing a
          new Security, pay or purchase such Security, as the case may be.

               Upon the issuance of any new Securities under this Section,
          the Company may require the payment of a sum sufficient to cover
          any tax or other governmental charge that may be imposed in
          relation thereto and any other expenses (including the fees and
          expenses of the Trustee) in connection therewith.

               Every new Security issued pursuant to this Section in lieu
          of any mutilated, destroyed, lost or stolen Security shall
          constitute an original additional contractual obligation of the
          Company, whether or not the destroyed, lost or stolen Security
          shall be at any time enforceable by anyone, and shall be entitled
          to all benefits of this Indenture equally and proportionately
          with any and all other Securities duly issued hereunder.

               The provisions of this Section are exclusive and shall
          preclude (to the extent lawful) all other rights and remedies
          with respect to the replacement or payment of mutilated,
          destroyed, lost or stolen Securities.

               SECTION 2.8.   OUTSTANDING SECURITIES; DETERMINATIONS OF
          HOLDERS' ACTION.  Securities outstanding at any time are all the
          Securities authenticated by the Trustee except for those
          cancelled by it, those delivered to it for cancellation,
          mutilated, destroyed, lost or stolen Securities for which the
          Trustee has authenticated and made available for delivery a new
          Security in lieu therefor pursuant to Section 2.7 and those
          described in this Section 2.8 as not outstanding.  A Security
          does not cease to be outstanding because the Company or an
          Affiliate thereof holds the Security; PROVIDED, HOWEVER, that in
          determining whether the Holders of the requisite Principal Amount
          of Securities have given or concurred in any request, demand,
          authorization, direction, notice, consent or waiver hereunder,
          Securities owned by the Company or any other obligor upon the
          Securities or any Affiliate of the Company or such other obligor
          shall be disregarded and deemed not to be outstanding, except
          that, in determining whether the Trustee shall be protected in
          relying upon any such request, demand, authorization, direction,
          notice, consent or waiver, only Securities which the Trustee
          knows to be so owned shall be so disregarded.  Subject to the
          foregoing, only Securities outstanding at the time of such
          determination shall be considered in any such determination


                                      10


<PAGE>

          (including, without limitation, determinations pursuant to
          Articles 6 and 9).

               If a Security is replaced pursuant to Section 2.7, it ceases
          to be outstanding unless the Trustee receives proof satisfactory
          to it that the replaced Security is held by a BONA FIDE
          purchaser.

               If the Paying Agent holds, in accordance with this
          Indenture, on a Redemption Date, or on the Business Day following
          a Purchase Date or a Change in Control Purchase Date, or on
          Stated Maturity, money or, if permitted by the terms hereof,
          securities sufficient to pay the Securities payable on that date,
          then on and after that date such Securities shall cease to be
          outstanding and Original Issue Discount and interest, if any, on
          such Securities shall cease to accrue and all other rights of the
          Holder shall terminate (other than the right to receive the
          applicable Redemption Price, Purchase Price or Change in Control
          Purchase Price, as the case may be, upon delivery of the Security
          in accordance with the terms of this Indenture); PROVIDED, that
          if such Securities are to be redeemed, notice of such redemption
          has been duly given pursuant to this Indenture or provision
          therefor satisfactory to the Trustee has been made.

               If a Security is converted in accordance with Article 11,
          then from and after the Conversion Date such Security shall cease
          to be outstanding and Original Issue Discount and interest, if
          any, shall cease to accrue on such Security.

               SECTION 2.9.   TEMPORARY SECURITIES.  Pending the
          preparation of definitive Securities, the Company may execute,
          and upon Company Order the Trustee shall authenticate and
          deliver, temporary Securities which are printed, lithographed,
          typewritten, mimeographed or otherwise produced, in any
          authorized denomination, substantially of the tenor of the
          definitive Securities in lieu of which they are issued and with
          such appropriate insertions, omissions, substitutions and other
          variations as the Officers executing such Securities may
          determine, as conclusively evidenced by their execution of such
          Securities.

               If temporary Securities are issued, the Company will cause
          definitive Securities to be prepared without unreasonable delay.
          After the preparation of definitive Securities, the temporary
          Securities shall be exchangeable for definitive Securities upon
          surrender of the temporary Securities at the office or agency of
          the Company designated for such purpose pursuant to Section 2.3
          or 4.5, without charge to the Holder.  Upon surrender for
          cancellation of any one or more temporary Securities the Company
          shall execute and the Trustee shall authenticate and deliver in
          exchange therefor a like Principal Amount of definitive


                                      11

<PAGE>

          Securities of authorized denominations.  Until so exchanged the
          temporary Securities shall in all respects be entitled to the
          same benefits under this Indenture as definitive Securities.

               SECTION 2.10.  CANCELLATION.  All Securities surrendered for
          payment, redemption or purchase by the Company pursuant to
          Article 3, conversion pursuant to Article 11, registration of
          transfer or exchange shall, if surrendered to any person other
          than the Trustee, be delivered to the Trustee and shall be
          promptly cancelled by it.  The Company may at any time deliver to
          the Trustee for cancellation any Securities previously
          authenticated and delivered hereunder which the Company may have
          acquired in any manner whatsoever, and all Securities so
          delivered shall be promptly cancelled by the Trustee.  The
          Company may not issue new Securities to replace Securities it has
          paid or delivered to the Trustee for cancellation or that any
          Holder has converted pursuant to Article 11.  No Securities shall
          be authenticated in lieu of or in exchange for any Securities
          cancelled as provided in this Section, except as expressly
          permitted by this Indenture.  All cancelled Securities held by
          the Trustee shall be disposed of by the Trustee in accordance
          with its normal procedures and evidence of such disposition shall
          be delivered to the Company unless the Company directs by Company
          Order that the Trustee deliver cancelled Securities to the
          Company.

                                      ARTICLE 3

                               REDEMPTION AND PURCHASES

               SECTION 3.1.   RIGHT TO REDEEM; NOTICES TO TRUSTEE.  The
          Company, at its option, may redeem the Securities for cash in
          accordance with the provisions set forth in paragraphs 5 and 7 of
          the Securities.  If the Company elects to redeem Securities
          pursuant to paragraph 5 of the Securities, it shall notify the
          Trustee in writing of the Redemption Date, the Principal Amount
          of Securities to be redeemed and the Redemption Price.

               The Company shall give the notice to the Trustee provided
          for in this Section 3.1 at least 60 days before the Redemption
          Date (unless a shorter notice shall be satisfactory to the
          Trustee).  If fewer than all the Securities are to be redeemed,
          the record date relating to such redemption shall be selected by
          the Company and given to the Trustee, which record date shall not
          be less than ten days after the date of notice to the Trustee.

               SECTION 3.2.   SELECTION OF SECURITIES TO BE REDEEMED.  If
          less than all the Securities are to be redeemed, the Trustee
          shall select the Securities to be redeemed PRO RATA or by lot or
          by any other method the Trustee considers fair and appropriate
          (so long as such method is not prohibited by the rules of any


                                      12


<PAGE>

          stock exchange on which the Securities are then listed).  The
          Trustee shall make the selection at least 35 but not more than 60
          days before the Redemption Date from outstanding Securities not
          previously called for redemption.  The Trustee may select for
          redemption portions of the Principal of Securities that have
          denominations larger than $1,000.  Securities and portions of
          them the Trustee selects shall be in Principal Amounts of $1,000
          or an integral multiple of $1,000.  Provisions of this Indenture
          that apply to Securities called for redemption also apply to
          portions of Securities called for redemption.  The Trustee shall
          notify the Company promptly, but not less than 35 days before the
          Redemption Date, of the Securities or portions of Securities to
          be redeemed.

               If any Security selected for partial redemption is
          thereafter surrendered for conversion in part before termination
          of the conversion right with respect to the portion of the
          Security so selected, the converted portion of such Security
          shall be deemed (so far as may be), solely for purposes of
          determining the aggregate Principal Amount of Securities to be
          redeemed by the Company, to be the portion selected for
          redemption.  Securities that have been converted during a
          selection of Securities to be redeemed may be treated by the
          Trustee as outstanding for the purpose of such selection.
          Nothing in this Section 3.2 shall affect the right of any Holder
          to convert any Security pursuant to Article 11 before the
          termination of the conversion right with respect thereto.

               SECTION 3.3.   NOTICE OF REDEMPTION.  At least 30 days but
          not more than 60 days before a Redemption Date, the Company shall
          mail a notice of redemption by first-class mail to each Holder of
          Securities to be redeemed in the manner provided in Section 12.2.

               The notice shall identify the Securities to be redeemed and
          shall state:

                    (1)  the Redemption Date;

                    (2)  the Redemption Price;

                    (3)  the Conversion Rate;

                    (4)  the name and address of the Paying Agent and
               Conversion Agent and of the office or agency referred to in
               Section 4.5;

                    (5)  that Securities called for redemption may be
               converted at any time before the close of business on the
               Redemption Date;


                                      13

<PAGE>

                    (6)  that Holders who want to convert Securities must
               satisfy the requirements set forth in paragraph 9 of the
               Securities;

                    (7)  that Securities called for redemption must be
               surrendered to the Paying Agent or at the office or agency
               referred to in Section 4.5 to collect the Redemption Price;

                    (8)  the CUSIP number of the Securities;

                    (9)  if fewer than all the outstanding Securities are
               to be redeemed, the certificate numbers and Principal
               Amounts of the particular Securities to be redeemed; and

                    (10) that, unless the Company defaults in payment of
               the Redemption Price, Original Issue Discount on Securities
               called for redemption and interest, if any, will cease to
               accrue on and after the Redemption Date.

               At the Company's written request, the Trustee shall give the
          notice of redemption in the Company's name and at the Company's
          expense.

               SECTION 3.4.   EFFECT OF NOTICE OF REDEMPTION.  Once notice
          of redemption is given, Securities called for redemption become
          due and payable on the Redemption Date stated in the notice and
          at the Redemption Price therefor except for Securities that are
          converted in accordance with the terms of this Indenture.  Upon
          the later of the Redemption Date and the date such Securities are
          surrendered to the Paying Agent or at the office or agency
          referred to in Section 4.5, such Securities called for redemption
          shall be paid at the Redemption Price therefor.

               SECTION 3.5.   DEPOSIT OF REDEMPTION PRICE.  Prior to or on
          the Redemption Date, the Company shall deposit with the Paying
          Agent (or if the Company or a Subsidiary or an Affiliate of
          either of them is the Paying Agent, shall segregate and hold in
          trust) money sufficient to pay the Redemption Price of all
          Securities to be redeemed on that date other than Securities or
          portions of Securities called for redemption which prior thereto
          have been delivered by the Company to the Trustee for
          cancellation.  The Paying Agent shall as promptly as practicable
          return to the Company any money, with interest, if any, thereon
          (subject to the provisions of Section 7.1(f)), not required for
          that purpose because of conversion of Securities pursuant to
          Article 11.  If such money is then held by the Company or a
          Subsidiary or an Affiliate of the Company in trust and is not
          required for such purpose it shall be discharged from such trust.


                                      14

               SECTION 3.6.   SECURITIES REDEEMED IN PART.  Upon surrender
          of a Security that is redeemed in part, the Company shall
          execute, and the Trustee shall authenticate and deliver to the
          Holder, a new Security in an authorized denomination equal in
          Principal Amount to the unredeemed portion of the Security
          surrendered.

               SECTION 3.7.   CONVERSION ARRANGEMENT ON CALL FOR
          REDEMPTION.  In connection with any redemption of Securities, the
          Company may arrange for the purchase and conversion of any
          Securities called for redemption by an agreement with one or more
          investment bankers or other purchasers to purchase all or a
          portion of such Securities by paying to the Trustee in trust for
          the Securityholders whose Securities are to be so purchased, on
          or before the close of business on the Redemption Date, an amount
          that, together with any amounts deposited with the Trustee by the
          Company for redemption of such Securities is not less than the
          Redemption Price, together with interest, if any, accrued to the
          Redemption Date, of such Securities.  Notwithstanding anything to
          the contrary contained in this Article 3, the obligation of the
          Company to pay the Redemption Price of such Securities, including
          all accrued interest, if any, shall be deemed to be satisfied and
          discharged to the extent such amount is so paid by such
          purchasers but no such agreement shall relieve the Company of its
          obligation to pay such Redemption Price and interest, if any.  If
          such an agreement is entered into, any Securities not duly
          surrendered for conversion by the Holders thereof may, at the
          option of the Company, be deemed, to the fullest extent permitted
          by law, acquired by such purchasers from such Holders and
          (notwithstanding anything to the contrary contained in Article
          11) surrendered by such purchasers for conversion, all as of
          immediately prior to the close of business on the Redemption
          Date, subject to payment of the above amount as aforesaid.  The
          Trustee shall hold and pay to the Holders whose Securities are
          selected for redemption any such amount paid to it for purchase
          and conversion in the same manner as it would moneys deposited
          with it by the Company for the redemption of Securities.  Without
          the Trustee's prior written consent, no arrangement between the
          Company and such purchasers for the purchase and conversion of
          any Securities shall increase or otherwise affect any of the
          powers, duties, responsibilities or obligations of the Trustee as
          set forth in this Indenture, and the Company agrees to indemnify
          the Trustee from, and hold it harmless against, any loss,
          liability or expense arising out of or in connection with any
          such arrangement for the purchase and conversion of any
          Securities between the Company and such purchasers, including the
          costs and expenses incurred by the Trustee in the defense of any
          claim or liability arising out of or in connection with the
          exercise or performance of any of its powers, duties,
          responsibilities or obligations under this Indenture.

               SECTION 3.8.   PURCHASE OF SECURITIES AT THE OPTION OF THE
          HOLDER.

               (a)  GENERAL.  Securities shall be purchased by the Company
          pursuant to paragraph 6 of the Securities as of June __, 1999, June
          __, 2004 and June __, 2009 (each, a "PURCHASE DATE"), at the
          purchase price specified therein (each, a "PURCHASE PRICE"), at
          the option of the Holder thereof, upon:

                    (1)  delivery to the Paying Agent or to the office or
               agency referred to in Section 4.5 by the Holder of a written
               notice of purchase (a "PURCHASE NOTICE") at any time from
               the opening of business on the date that is 20 Business Days
               prior to a Purchase Date until the close of business on such
               Purchase Date stating:

                         (A)  the certificate number of the Security that
                    the Holder will deliver to be purchased;

                         (B)  the portion of the Principal Amount of the
                    Security which the Holder will deliver to be purchased,
                    which portion must be $1,000 or an integral multiple
                    thereof;

                         (C)  that such Security shall be purchased on the
                    Purchase Date pursuant to the terms and conditions
                    specified in this Indenture and in paragraph 6 of the
                    Securities; and

                         (D)  whether, if the Company elects pursuant to
                    Section 3.8(b) to pay the Purchase Price on such
                    Purchase Date, in whole or in part, in shares of Common
                    Stock, but such portion of the Purchase Price to be
                    paid in Common Stock is ultimately to be paid in cash
                    because any condition in Section 3.8(d) is not
                    satisfied, such Holder elects (i) to withdraw such
                    Purchase Notice as to some or all of the Securities to
                    which it relates (stating the Principal Amount and
                    certificate numbers of the Securities as to which such
                    withdrawal shall relate), or (ii) to receive cash in
                    respect of the Purchase Price for all Securities
                    subject to such Purchase Notice; and

                    (2)  delivery of such Security, by hand or by
               registered mail prior to, on or after the Purchase Date
               (together with all necessary endorsements) to the Paying
               Agent at the offices of the Paying Agent or to the office or
               agency referred to in Section 4.5, such delivery being a
               condition to receipt by the Holder of the Purchase Price
               therefor; PROVIDED, HOWEVER, that such Purchase Price shall
               be so paid pursuant to this Section 3.8 only if the Security


                                      16

<PAGE>

               so delivered conforms in all respects to the description
               thereof in the related Purchase Notice.

               If a Holder, in such Holder's Purchase Notice and in any
          written notice of withdrawal delivered by such Holder pursuant to
          the terms of Section 3.10, fails to indicate such Holder's choice
          with respect to the election set forth in clause (D) of Section
          3.8(a)(1), such Holder shall be deemed to have elected to receive
          cash in respect of the Purchase Price otherwise payable in Common
          Stock.

               The Company shall purchase from the Holder thereof, pursuant
          to this Section 3.8, a portion of a Security if the Principal
          Amount of such portion is $1,000 or an integral multiple of
          $1,000.  Provisions of this Indenture that apply to the purchase
          of all of a Security also apply to the purchase of such portion
          of such Security.

               Any purchase by the Company contemplated pursuant to the
          provisions hereof shall be consummated by the delivery of the
          consideration to be received by the Holder promptly following the
          later of the Purchase Date and the time of delivery of the
          Security.

               Notwithstanding anything herein to the contrary, any Holder
          delivering to the Paying Agent or the office or agency referred
          to in Section 4.5 the Purchase Notice contemplated by this
          Section 3.8(a) shall have the right to withdraw at any time prior
          to the close of business on the Purchase Date such Purchase
          Notice by delivery of a written notice of withdrawal to the
          Paying Agent or such office or agency in accordance with Section
          3.10.

               The Paying Agent shall promptly notify the Company of the
          receipt by it of any Purchase Notice or written notice of
          withdrawal thereof.

               (b)  COMPANY'S RIGHT TO ELECT MANNER OF PAYMENT OF PURCHASE
          PRICE.  The Securities to be purchased pursuant to Section 3.8(a)
          may be paid for, at the election of the Company, in cash or
          Common Stock, or in any combination of cash and Common Stock,
          subject to the conditions set forth in this Section 3.8.  The
          Company shall designate, in the notice from the Company delivered
          pursuant to Section 3.8(e), whether the Company will purchase the
          Securities for cash or Common Stock, and, if a combination
          thereof, the percentages of the Purchase Price of Securities in
          respect of which it will pay in cash or Common Stock; PROVIDED
          that the Company will pay cash for fractional interests in Common
          Stock.  For purposes of determining the existence of potential
          fractional interests, all Securities subject to purchase by the
          Company held by a Holder shall be considered together (no matter


                                      17

<PAGE>

          how many separate certificates are to be presented).  Each Holder
          whose Securities are purchased pursuant to this Section 3.8 shall
          receive the same percentage of cash or Common Stock in payment of
          the Purchase Price for such Securities, except (i) as provided in
          Section 3.8(d) with regard to the payment of cash in lieu of
          fractional shares of Common Stock and (ii) in the event that the
          Company is unable to purchase the Securities of a Holder or
          Holders for Common Stock because any necessary qualifications or
          registrations of the Common Stock under applicable state
          securities laws cannot be obtained, the Company may purchase the
          Securities of such Holder or Holders for cash.  The Company may
          not change its election with respect to the consideration (or
          components or percentages of components thereof) to be paid once
          the Company has given notice thereof to Securityholders except
          pursuant to this Section 3.8(b) or Section 3.8(d).



               At least five Business Days before the Company Notice Date
          (as defined below), the Company shall deliver an Officers'
          Certificate to the Trustee specifying:

                    (i)  the manner of payment selected by the Company;

                    (ii)  the information required by Section 3.8(e);

                    (iii)  that the conditions to such manner of payment
               set forth in Section 3.8(d), as the case may be, have or
               will be complied with; and

                    (iv)  whether the Company desires the Trustee to give
               the notice required by Section 3.8(e).

               (c)  PURCHASE WITH CASH.  On each Purchase Date, at the
          option of the Company, the Principal Amount of the Securities in
          respect of which a Purchase Notice pursuant to Section 3.8(a) has
          been given, or a specified percentage thereof, may be purchased
          by the Company with cash equal to the aggregate Purchase Price of
          such Securities.  If the Company elects to purchase Securities
          with cash, notice as provided in Section 3.8(e) shall be sent to
          Holders (and to beneficial owners if required by applicable law,
          including without limitation, Rule 13e-4 ("RULE 13e-4", which
          term, as used herein, includes any successor provision thereto)
          under the Securities Exchange Act of 1934 (the "EXCHANGE ACT")
          not less than 20 Business Days prior to the Purchase Date (the
          "COMPANY NOTICE DATE").

               (d)  PAYMENT BY ISSUANCE OF COMMON STOCK.  On each Purchase
          Date, at the option of the Company, the Principal Amount of the
          Securities in respect of which a Purchase Notice pursuant to
          Section 3.8(a) has been given, or a specified percentage thereof,
          may be purchased by the Company by the issuance of a number of
          shares of Common Stock equal to the quotient obtained by dividing


                                      18


<PAGE>

          (i) the amount of cash to which the Securityholders would have
          been entitled had the Company elected to pay all or such
          specified percentage, as the case may be, of the Purchase Price
          of such Securities in cash by (ii) the Market Price (as defined
          below) of a share of Common Stock, subject to the next succeeding
          paragraph.

               The Company will not issue a fractional share of Common
          Stock in payment of the Purchase Price.  Instead the Company will
          pay cash for the current market value of the fractional share.
          The current market value of a fraction of a share shall be
          determined by multiplying the Market Price by such fraction and
          rounding the product to the nearest whole cent, with one-half
          cent being rounded upward.  It is understood that if a Holder
          elects to have more than one Security purchased, the number of
          shares of Common Stock shall be based on the aggregate amount of
          Securities to be purchased.

               If the Company elects to purchase the Securities by the
          issuance of shares of Common Stock, notice as provided in Section
          3.8(e) shall be sent to the Holders (and to beneficial owners if
          required by applicable law, including without limitation, Rule
          13e-4) not later than the Company Notice Date.

               The Company's right to exercise its election to purchase the
          Securities pursuant to Section 3.8 through the issuance of shares
          of Common Stock shall be conditioned upon:

                    (i)  the Company's not having given notice of an
               election to pay entirely in cash and its giving of timely
               notice of election to purchase all or a specified percentage
               of the Securities with Common Stock as provided herein;

                    (ii)  the registration of the shares of Common Stock to
               be issued in respect of the payment of the Purchase Price
               under the Securities Act of 1933 (the "SECURITIES ACT") and
               the Exchange Act, in each case if required;

                    (iii)  any necessary qualification or registration
               under applicable state securities laws or the availability
               of an exemption from such qualification and registration and
               compliance with other applicable federal securities laws;
               and

                    (iv)  the receipt by the Trustee of an Officers'
               Certificate and an Opinion of Counsel each stating that (A)
               the terms of the issuance of the Common Stock are in
               conformity with this Indenture and (B) the shares of Common
               Stock to be issued by the Company in payment of the Purchase
               Price in respect of Securities have been duly authorized
               and, when issued and delivered pursuant to the terms of this


                                      19

<PAGE>

               Indenture in payment of the Purchase Price in respect of the
               Securities, will be validly issued, fully paid and
               nonassessable and shall be free of any preemptive rights and
               any lien or adverse claim (provided that such Opinion of
               Counsel may state that, insofar as it relates to the absence
               of such preemptive rights, liens and adverse claims, it is
               given upon the best knowledge of such counsel), and, in the
               case of such Officers' Certificate, that conditions (i),
               (ii) and (iii) above have been satisfied and, in the case of
               such Opinion of Counsel, that conditions (ii) and (iii) (but
               only with respect to compliance with applicable federal
               securities laws) above have been satisfied.

          Such Officers' Certificate shall also set forth the number of
          shares of Common Stock to be issued for each $1,000 Principal
          Amount of Securities and the Sale Price (as defined below) of a
          share of Common Stock on each of the seven Business Days prior to
          the Purchase Date.  The Company may elect to pay in Common Stock
          only if the information necessary to calculate the Market Price
          is reported in THE WALL STREET JOURNAL or another daily newspaper
          of national circulation.  If such conditions are not satisfied
          prior to or on the Purchase Date and the Company elected to
          purchase the Securities pursuant to this Section 3.8 through the
          issuance of shares of Common Stock, the Company shall pay the
          Purchase Price in cash.

               The "MARKET PRICE" means the average of the Sale Price of
          the Common Stock for the five Trading Day period ending on the
          third Trading Day prior to the related Purchase Date,
          appropriately adjusted to take into account the actual
          occurrence, during the seven Trading Days preceding such Purchase
          Date, of any event described in Section 11.6, 11.7 or 11.8;
          subject, however, to the conditions set forth in Sections 11.9
          and 11.10.

               The "SALE PRICE" of the Common Stock on any date means the
          closing per share sale price (or if no closing sale price is
          reported, the average of the bid and ask prices or, if more than
          one in either case the average of the average bid and the average
          ask prices) on such date as reported in composite transactions
          for the principal United States securities exchange on which the
          Common Stock is traded or, if the Common Stock is not listed on a
          United States national or regional stock exchange, as reported by
          the National Association of Securities Dealers Automated
          Quotation System.

               (e)  NOTICE OF ELECTION.  The Company shall send notices of
          its election to purchase with cash or Common Stock or any
          combination thereof to the Holders (and to beneficial owners if

          specified in Section 3.8(c) or (d), as applicable.  Such notices
          shall state the manner of payment elected and shall contain the
          following information:

               In the event the Company has elected to pay the Purchase
          Price (or any specified percentage thereof) with Common Stock,
          the notice shall:

                    (1)  state that each Holder will receive Common Stock
               with a Market Price determined as of a specified date prior
               to the Purchase Date equal to such specified percentage of
               the Purchase Price of the Securities held by such Holder
               (except for any cash amount to be paid in lieu of fractional
               shares); and

                    (2)  state that because the Market Price of Common
               Stock will be determined prior to the Purchase Date, Holders
               will bear the market risk with respect to the value of the
               Common Stock to be received from the date such Market Price
               is determined to the Purchase Date.

               In any case, each notice shall include a form of Purchase
          Notice to be completed by the Securityholder and shall state:

                    (i)  the Purchase Price and Conversion Rate;

                    (ii)  the name and address of the Paying Agent and the
               Conversion Agent and of the office or agency referred to in
               Section 4.5;

                    (iii)  that Securities as to which a Purchase Notice
               has been given may be converted only if the applicable
               Purchase Notice has been withdrawn in accordance with the
               terms of this Indenture;

                    (iv)  that Securities must be surrendered to the Paying
               Agent or to the office or agency referred to in Section 4.5
               to collect payment;

                    (v)  that the Purchase Price for any security as to
               which a Purchase Notice has been given and not withdrawn
               will be paid promptly following the later of the Purchase
               Date and the time of surrender of such Security as described
               in (iv);

                    (vi)  the procedures the Holder must follow to exercise
               rights under Section 3.8 and a brief description of those
               rights;

                    (vii)  briefly, the conversion rights of the
               Securities; and

<PAGE>

                    (viii)  the procedures for withdrawing a Purchase
               Notice.

               At the Company's written request, the Trustee shall give
          such notice in the Company's name and at the Company's expense;
          PROVIDED, HOWEVER, that, in all cases, the text of such notice
          shall be prepared by the Company.

               Upon determination of the actual number of shares of Common
          Stock to be issued for each $1,000 Principal Amount of
          Securities, the Company will publish such determination in THE
          WALL STREET JOURNAL or another daily newspaper of national
          circulation and furnish the Trustee with an affidavit of
          publication.

               (f)  COVENANTS OF THE COMPANY.  All shares of Common Stock
          delivered upon purchase of the Securities shall be newly issued
          shares or treasury shares, shall be duly authorized, validly
          issued, fully paid and nonassessable and shall be free from
          preemptive rights and free of any lien or adverse claim.

               The Company shall use its best efforts to list or cause to
          have quoted any shares of Common Stock to be issued to purchase
          Securities on each national securities exchange or over-the-
          counter or other domestic market on which any other shares of the
          Common Stock are then listed or quoted.  The Company will
          promptly inform the Trustee in writing of any such listing.

               (g)  PROCEDURE UPON PURCHASE.  The Company shall deposit
          cash (in respect of a cash purchase under Section 3.8(c) or for
          fractional interests, as applicable) or shares of Common Stock,
          or any combination thereof, as applicable, at the time and in the
          manner as provided in Section 3.11, sufficient to pay the
          aggregate Purchase Price of all Securities to be purchased
          pursuant to this Section 3.8.  As soon as practicable after the
          later of the Purchase Date and the date such Securities are
          surrendered to the Paying Agent or at the office or agency
          referred to in Section 4.5, the Company shall deliver to each
          Holder entitled to receive Common Stock through the Paying Agent
          a certificate for the number of full shares of Common Stock
          issuable in payment of the Purchase Price and cash in lieu of any
          fractional interests.  The person in whose name the certificate
          for Common Stock is registered shall be treated as a holder of
          record of such Common Stock on the Business Day following the
          related Purchase Date.  Subject to Section 3.8(d), no payment or
          adjustment will be made for dividends on the Common Stock the
          record date for which occurred prior to the Purchase Date.

               (h)  TAXES.  If a Holder of a Security is paid in Common
          Stock, the Company shall pay any documentary, stamp or similar
          issue or transfer tax due on such issue of shares of Common


                                      22

<PAGE>

          Stock.  However, the Holder shall pay any such tax which is due
          because the Holder requests the shares of Common Stock to be
          issued in a name other than the Holder's name.  The Paying Agent
          may refuse to deliver the certificates representing the Common
          Stock being issued in a name other than the Holder's name until
          the Paying Agent receives a sum sufficient to pay any tax which
          will be due because the shares of Common Stock are to be issued
          in a name other than the Holder's name.  Nothing herein shall
          preclude any income tax withholding required by law or
          regulations.


               SECTION 3.9.   PURCHASE OF SECURITIES AT OPTION OF THE
          HOLDER UPON CHANGE IN CONTROL.  (a)  If on or prior to June __,
          1999 there shall have occurred a Change in Control, Securities
          shall be purchased, at the option of the Holder thereof, by the
          Company at the purchase price specified in paragraph 6 of the
          Securities (the "CHANGE IN CONTROL PURCHASE PRICE"), on the date
          that is 35 Business Days after the occurrence of the Change of
          Control (the "CHANGE IN CONTROL PURCHASE DATE"), subject to
          satisfaction by or on behalf of the Holder of the requirements
          set forth in Section 3.9(c).

               A "CHANGE IN CONTROL" shall be deemed to have occurred at
          such time as either of the following events shall occur:

                    (i)  There shall be consummated any consolidation or
               merger of the Company (A) in which the Company is not the
               continuing or surviving corporation or (B) pursuant to which
               the Voting Stock (as defined below) of the Company would be
               converted into cash, securities or other property, in each
               case other than a consolidation or merger of the Company in
               which the holders of Voting Stock of the Company immediately
               prior to the consolidation or merger have, directly or
               indirectly, at least a majority of the Voting Stock of the
               surviving corporation immediately after such consolidation
               or merger; or

                    (ii)  There is a report filed by any person, including
               that person's Affiliates and Associates, on Schedule 13D or
               14D-1 (or any successor schedule, form or report) pursuant
               to the Exchange Act, disclosing that such person (for the
               purposes of this Section 3.9 only, the term "person" shall
               include a "person" within the meaning of Section 13(d)(3) or
               Section 14(d)(2) of the Exchange Act or any successor
               provision to either of the foregoing) has become the
               beneficial owner (as the term "BENEFICIAL OWNER" is defined
               under Rule 13d-3 or any successor rule or regulation
               promulgated under the Exchange Act) of 50% or more of the
               voting power of the Company's Voting Stock then outstanding;
               PROVIDED, HOWEVER, that a person shall not be deemed


                                      23

<PAGE>

               beneficial owner of, or to own beneficially, (A) any
               securities tendered pursuant to a tender or exchange offer
               made by or on behalf of such person or any of such person's
               Affiliates or Associates until such tendered securities are
               accepted for purchase or exchange thereunder, or (B) any
               securities if such beneficial ownership (1) arises solely as
               a result of a revocable proxy delivered in response to a
               proxy or consent solicitation made pursuant to, and in
               accordance with, the applicable rules and regulations under
               the Exchange Act, and (2) is not also then reportable on
               Schedule 13D (or any successor schedule, form or report)
               under the Exchange Act.

          Notwithstanding the foregoing provisions of this Section 3.9, a
          Change in Control shall not be deemed to have occurred if at any
          time the Company, any Subsidiary, any employee stock ownership
          plan or any other employee benefit plan of the Company or any
          Subsidiary, or any person holding Voting Stock for or pursuant to
          the terms of any such employee benefit plan, files or becomes
          obligated to file a report under or in response to Schedule 13D
          or Schedule 14D-1 (or any successor schedule, form or report)
          under the Exchange Act disclosing beneficial ownership by it of
          shares of Voting Stock, whether in excess of 50% or otherwise.

               "VOTING STOCK" means, with respect to any person, the
          capital stock of such person having general voting power under
          ordinary circumstances to elect at least a majority of the board
          of directors, managers or trustees of such person (irrespective
          of whether or not at the time capital stock of any other class or
          classes shall have or might have voting power by reason of the
          happening of any contingency).

               "ASSOCIATE" shall have the meaning ascribed to such term in
          Rule 12b-2 of the General Rules and Regulations under the
          Exchange Act, as in effect on the date hereof.

               (b)  Within 15 Business Days after the occurrence of a
          Change in Control, the Company shall mail a written notice of
          such Change in Control by first-class mail to the Trustee and to
          each Holder (and to beneficial owners if required by applicable
          law, including without limitation, Rule 13e-4) and shall cause a
          copy of such notice to be published in THE WALL STREET JOURNAL or
          another daily newspaper of national circulation.  The notice
          shall include a form of Change in Control Purchase Notice to be
          completed by the Securityholder and shall state:

                    (1)  the events causing a Change in Control and the
               date of such Change in Control;

                    (2)  the date by which the Change in Control Purchase
               Notice pursuant to this Section 3.9 must be given;

                    (3)  the Change in Control Purchase Date;

                    (4)  the Change in Control Purchase Price;

               Conversion Agent and the office or agency referred to in
               Section 4.5;

                    (6)  the Conversion Rate and any adjustments thereto;

                    (7)  that Securities as to which a Change in Control
               Purchase Notice has been given may be converted into Common
               Stock only if the Change in Control Purchase Notice has been
               withdrawn in accordance with the terms of this Indenture;

                    (8)  that Securities must be surrendered to the Paying
               Agent or the office or agency referred to in Section 4.5 to
               collect payment;

                    (9)  that the Purchase Price for any Security as to
               which a Purchase Notice has been duly given and not
               withdrawn will be paid promptly following the later of the
               Change in Control Purchase Date and the time of surrender of
               such Security as described in (8);

                    (10)  the procedures the Holder must follow to exercise
               rights under this Section 3.9 and a brief description of
               those rights;

                    (11)  briefly, the conversion rights of the Securities;

                    (12)  the procedures for withdrawing a Change in
               Control Purchase Notice.

               (c)  A Holder may exercise its rights specified in Section
          3.9(a) upon delivery of a written notice of purchase (a "CHANGE
          IN CONTROL PURCHASE NOTICE") to the Paying Agent or to the office
          or agency referred to in Section 4.5 at any time prior to the
          close of business on the Change in Control Purchase Date,
          stating:

                    (1)  the certificate number of the Security which the
               Holder will deliver to be purchased;

                    (2)  the portion of the Principal Amount of the
               Security which the Holder will deliver to be purchased,
               which portion must be $1,000 or an integral multiple
               thereof; and


                                      25

<PAGE>

                    (3)  that such Security shall be purchased on the
               Change in Control Purchase Date pursuant to the terms and
               conditions specified in paragraph 6 of the Securities.

               The delivery of the Security, by hand or by registered mail
          prior to, on or after the Change in Control Purchase Date
          (together with all necessary endorsements), to the Paying Agent
          at the offices of the Paying Agent or to the office or agency
          referred to in Section 4.5 shall be a condition to the receipt by
          the Holder of the Change in Control Purchase Price therefor;
          PROVIDED, HOWEVER, that such Change in Control Purchase Price
          shall be so paid pursuant to this Section 3.9 only if the
          Security so delivered to the Paying Agent or such office or
          agency shall conform in all respects to the description thereof
          set forth in the related Change in Control Purchase Notice.

               The Company shall purchase from the Holder thereof, pursuant
          to this Section 3.9, a portion of a Security if the Principal
          Amount of such portion is $1,000 or an integral multiple of
          $1,000.  Provisions of this Indenture that apply to the purchase
          of all of a Security also apply to the purchase of such portion
          of such Security.

               Any purchase by the Company contemplated pursuant to the
          provisions of this Section 3.9 shall be consummated by the

          promptly following the later of the Change in Control Purchase
          Date and the date such Securities are surrendered to the Paying
          Agent or at the office or agency referred to in Section 4.5.

               Notwithstanding anything herein to the contrary, any Holder
          delivering to the Paying Agent or to the office or agency
          referred to in Section 4.5 the Change in Control Purchase Notice
          contemplated by this Section 3.9(c) shall have the right to
          withdraw such Change in Control Purchase Notice at any time prior
          to or on the Change in Control Purchase Date by delivery of a
          written notice of withdrawal to the Paying Agent or to such
          office or agency in accordance with Section 3.10.

               The Paying Agent shall promptly notify the Company of the
          receipt by it of any Change in Control Purchase Notice or written
          withdrawal thereof.

               SECTION 3.10.  EFFECT OF PURCHASE NOTICE OR CHANGE IN
          CONTROL PURCHASE NOTICE.  Upon receipt by the Paying Agent of the
          Purchase Notice or Change in Control Purchase Notice specified in
          Section 3.8(a) or Section 3.9(c), as applicable, the Holder of
          the Security in respect of which such Purchase Notice or Change
          in Control Purchase Notice, as the case may be, was given shall

          is withdrawn as specified in the following two paragraphs)

          thereafter be entitled to receive solely the Purchase Price or
          Change in Control Purchase Price, as the case may be, with

          Control Purchase Price shall be paid to such Holder promptly
          following the later of (x) the Business Day following the
          Purchase Date or the Change in Control Purchase Date, as the case
          may be, with respect to such Security (provided the conditions in

          satisfied) and (y) the time of delivery of such Security to the
          Paying Agent or to the office or agency referred to in Section
          4.5 by the Holder thereof in the manner required by Section

          respect of which a Purchase Notice or Change in Control Purchase
          Notice, as the case may be, has been given by the Holder thereof
          may not be converted into shares of Common Stock on or after the
          date of the delivery of such Purchase Notice or Change in Control
          Purchase Notice, as the case may be, unless such Purchase Notice
          or Change in Control Purchase Notice, as the case may be, has
          first been validly withdrawn as specified in the following two
          paragraphs.

          withdrawal delivered to the office of the Paying Agent or to the

          Date, as the case may be, specifying:

                    (1)  the certificate number of the Security in respect
               of which such notice of withdrawal is being submitted;

                    (2)  the Principal Amount of the Security with respect
               to which such notice of withdrawal is being submitted; and

               which remains subject to the original Purchase Notice or
               Change in Control Purchase Notice, as the case may be, and
               which has been or will be delivered for purchase by the
               Company.

               A written notice of withdrawal of a Purchase Notice may be
          in the form set forth in the preceding paragraph or may be in the
          form of (i) a conditional withdrawal contained in a Purchase
          Notice pursuant to the terms of Section 3.8(a)(1)(D) or (ii) a
          conditional withdrawal containing the information set forth in

          set forth in the preceding paragraph.

               There shall be no purchase of any Securities pursuant to
          Sections 3.8 (other than through the issuance of Common Stock) or

          3.9 if there has occurred (prior to, on or after, as the case may
          be, the giving, by the Holders of such Securities, of the
          required Purchase Notice or Change in Control Purchase Notice, as
          the case may be) and is continuing an Event of Default (other
          than a default in the payment of the Purchase Price or Change in
          Control Purchase Price, as the case may be, with respect to such
          Securities).

               SECTION 3.11.  DEPOSIT OF PURCHASE PRICE OR CHANGE IN
          CONTROL PURCHASE PRICE.  Prior to 3:00 p.m. (local time in The
          City of New York) on the Business Day following the Purchase Date
          or the Change in Control Purchase Date, as the case may be, the
          Company shall deposit with the Trustee or with the Paying Agent
          (or, if the Company or a Subsidiary or an Affiliate of either of
          them is acting as Paying Agent, shall segregate and hold in trust
          as provided in Section 2.4) an amount of cash in immediately
          available funds or securities, if expressly permitted hereunder,
          sufficient to pay the aggregate Purchase Price or Change in
          Control Purchase Price, as the case may be, of all the Securities
          or portions thereof which are to be purchased.

               SECTION 3.12.  SECURITIES PURCHASED IN PART.  Any Security
          which is to be purchased only in part shall be surrendered at the
          office of the Paying Agent or the office or agency referred to in
          Section 4.5 (with, if the Company or the Trustee so requires, due
          endorsement, or a written instrument of transfer in form
          satisfactory to the Company and the Trustee executed by the
          Holder or such Holder's attorney duly authorized in writing) and
          the Company shall execute and the Trustee shall authenticate and
          deliver to the Holder of such Security, without service charge, a
          new Security or Securities, of any authorized denomination as
          requested by such Holder in aggregate Principal Amount equal to,
          and in exchange for, the portion of the Principal Amount of the
          Security so surrendered which is not purchased.

               SECTION 3.13.  COVENANT TO COMPLY WITH SECURITIES LAWS UPON
          PURCHASE OF SECURITIES.  In connection with any offer to purchase
          or purchase of Securities under Section 3.8 or 3.9 hereof, the
          Company shall (i) comply with Rule 13e-4, if applicable, (ii)
          file the related Schedule 13E-4 (or any successor schedule, form
          or report) under the Exchange Act, if applicable, and (iii)
          otherwise comply with all Federal and state securities laws
          regulating the offer and delivery of shares of Common Stock upon
          purchase of the Securities (including positions of the SEC under
          applicable no-action letters) so as to permit the rights and
          obligations under Sections 3.8 and 3.9 to be exercised in the
          time and in the manner specified in Sections 3.8 and 3.9.

               SECTION 3.14.  REPAYMENT TO THE COMPANY.  The Trustee and
          the Paying Agent shall return to the Company any cash or shares
          of Common Stock, together with interest on such cash, if any, or


                                      28

<PAGE>

          dividends on such shares of Common Stock, if any, (subject to the
          provisions of Section 7.1(f)) held by them for the payment of a
          Purchase Price or Change in Control Purchase Price, as the case
          may be, of the Securities that remain unclaimed as provided in
          paragraph 13 of the Securities; PROVIDED, HOWEVER, that to the
          extent that the aggregate amount of cash or shares of Common
          Stock deposited by the Company pursuant to Section 3.11 exceeds
          the aggregate Purchase Price or Change in Control Purchase Price,
          as the case may be, of the Securities or portions thereof to be
          purchased, then promptly after the Business Day following the
          Purchase Date or Change in Control Purchase Date, as the case may
          be, the Trustee shall return any such excess to the Company
          together with interest or dividends, if any, thereon (subject to
          the provision of Section 7.1(f)).


                                      ARTICLE 4

                                      COVENANTS

               SECTION 4.1.   PAYMENT OF SECURITIES.  The Company shall
          promptly make all payments in respect of the Securities on the
          dates and in the manner provided in the Securities or pursuant to
          this Indenture.  Principal Amount, Issue Price, accrued Original
          Issue Discount, Redemption Price, Purchase Price, Change in
          Control Purchase Price and interest, if any, shall be considered
          paid on the applicable date due if on such date the Trustee or
          the Paying Agent holds, in accordance with this Indenture, cash
          or securities, if expressly permitted hereunder, sufficient to
          pay all such amounts then due.

               The Company shall, to the extent permitted by law, pay
          interest on overdue amounts at the per annum rate of interest set
          forth in paragraph 1 of the Securities, which interest on overdue
          amounts shall accrue from the date such amounts were originally
          due and payable.

               SECTION 4.2.   SEC REPORTS.  The Company shall file with the
          Trustee, within 15 days after it files such annual and quarterly
          reports, information, documents and other reports with the SEC,
          copies of its annual and quarterly reports and of the
          information, documents and other reports (or copies of such
          portions of any of the foregoing as the SEC may by rules and
          regulations prescribe) which the Company is required to file with
          the SEC pursuant to Section 13 or 15(d) of the Exchange Act (or
          any such successor provisions thereto).  In the event the Company
          is at any time no longer subject to the reporting requirements of
          Section 13 or 15(d) of the Exchange Act (or any such successor
          provisions), it shall continue to provide the Trustee with
          reports containing substantially the same information as would
          have been required to be filed with the SEC had the Company


                                      29

<PAGE>

          continued to have been subject to such reporting requirements,
          and the Trustee shall make any such reports available to
          Securityholders upon request.  In such event, such reports shall
          be provided at the times the Company would have been required to
          provide reports had it continued to have been subject to such
          reporting requirements.  The Company also shall comply with the
          other provisions of TIA Section 314(a).

               SECTION 4.3.   COMPLIANCE CERTIFICATE; NOTICE OF DEFAULTS.
          (a)  The Company shall deliver to the Trustee within 120 days
          after the end of each fiscal year of the Company (beginning with
          the fiscal year ending on December 3l, 1994) an Officers'
          Certificate stating whether or not the signers know of any
          Default that occurred during such period.  If they do, such
          Officers' Certificate shall describe the Default and its status.

               (b)  The Company shall file with the Trustee written notice
          of the occurrence of any Default or Event of Default within five
          Business Days of its becoming aware of such Default or Event of
          Default.

               SECTION 4.4.   FURTHER INSTRUMENTS AND ACTS.  Upon request
          of the Trustee, the Company will execute and deliver such further
          instruments and do such further acts as may be reasonably
          necessary or proper to carry out more effectively the purposes of
          this Indenture.

               SECTION 4.5.   MAINTENANCE OF OFFICE OR AGENCY.  The Company
          will maintain in the Borough of Manhattan, The City of New York,
          in such location as may be required by the rules of any
          securities exchange or quotation system on which the Securities
          may from time to time be listed, an office or agency where
          Securities may be presented or surrendered for payment, where
          Securities may be surrendered for registration of transfer,
          exchange, purchase, redemption or conversion and where notices
          and demands to or upon the Company in respect of the Securities
          and this Indenture may be served.  The corporate trust office of
          the Trustee in The City of New York, at which at any particular
          time its corporate trust business shall be administered, which
          office on the date hereof is located at One New York Plaza, 14th
          Floor, New York, N.Y. 10081, shall be such office or agency for
          all of the aforesaid purposes unless the Company shall maintain
          some other office or agency for such purposes and shall give prompt
          written notice to the Trustee and the Holders of the location, and
          any change of location, of such other office or agency.  If at any
          time the Company shall fail to maintain any such required office or
          agency or shall fail to furnish the Trustee with the address
          thereof, such presentations, surrenders, notices and demands may be
          made or served at the address of the Trustee set forth in Section
          12.2.


                                      30

     The Company may also from time to time designate one or more other
offices or agencies where the Securities may be presented or surrendered for
any or all such purposes and may from time to time rescind such designations;
PROVIDED, HOWEVER, that no such designation or rescission shall in any manner
relieve the Company of its obligation to maintain an office or agency in The
City of New York, for such purposes.

                            SUCCESSOR CORPORATION

     SECTION 5.1    WHEN COMPANY MAY MERGE OR TRANSFER ASSETS.  The Company,
in a single transaction or through a series of related transactions, shall not
consolidate with or merge with or into any other person or transfer (by
lease, assignment, sale or otherwise) all or substantially all of its
properties and assets to another person or group of affiliated persons,
unless:

          (a)  either (1) the Company shall be the continuing corporation or
     (2) the person (if other than the Company) formed by such consolidation
     or into which the Company is merged or to which all or substantially all
     of the properties and assets of the Company are transferred (i) shall be
     a corporation, partnership or trust organized and validly existing under
     the laws of the United States or any State thereof or the District of
     Columbia and (ii) shall expressly assume, by an indenture supplemental
     hereto, executed and delivered to the Trustee, in form satisfactory to
     the Trustee, all of the obligations of the Company under the Securities
     and this Indenture;

          (b)  immediately after giving effect to such transaction, and the
     assumption contemplated by clause (a) above, no Default or Event of
     Default shall have occurred and be continuing; and

          (c)  the Company shall have delivered to the Trustee an Officers'
     Certificate and an Opinion of Counsel, each stating that such
     consolidation, merger or transfer and, if a supplemental indenture is
     required in connection with such transaction, such supplemental
     indenture, comply with this Article and that all conditions precedent
     herein provided for relating to such transaction have been satisfied.

     For purposes of the foregoing, the transfer (by lease, assignment, sale
or otherwise) of the properties and assets of one or more Subsidiaries (other
than to the Company or another wholly owned Subsidiary), which, if such
assets were owned by the Company, would constitute all or substantially all
of the


                                      31

<PAGE>

properties and assets of the Company, shall be deemed to be the transfer of
all or substantially all of the properties and assets of the Company.

     The successor person formed by such consolidation or into which the
Company is merged or the successor person to which such conveyance, transfer
or lease is made shall succeed to, and be substituted for, and may exercise
every right and power of, the Company under this Indenture with the same
effect as if such successor had been named as the Company herein; and
thereafter, except in the case of (i) a lease of its properties and assets
substantially as an entirety and (ii) obligations the Company may have under
a supplemental indenture pursuant to Section 11.14, the Company shall be
discharged and released from all obligations and covenants under this
Indenture and the Securities.  The Trustee shall enter into a supplemental
indenture to evidence the succession and substitution of such successor
person and such discharge and release of the Company.

                            DEFAULTS AND REMEDIES

     SECTION 6.1.   EVENTS OF DEFAULT.  An "EVENT OF DEFAULT" occurs if:

          (1)  the Company defaults in the payment of the Principal Amount,
     Issue Price, accrued Original Issue Discount, Redemption Price, Purchase
     Price or Change in Control Purchase Price on any Security when the same
     becomes due and payable at its Stated Maturity, upon redemption, upon
     declaration, when due for purchase by the Company or otherwise, whether
     or not such payment shall be prohibited by Article 10;

          (2)  the Company fails to comply with any of its agreements in the
     Securities or this Indenture (other than those referred to in clause (1)
     above) and such failure continues for 60 days after receipt by the
     Company of a Notice of Default;

          (3)  the Company pursuant to or within the meaning of any
     Bankruptcy Law:

               (A)  commences a voluntary case or proceeding;

               (B)  consents to the entry of an order for relief against it
          in an involuntary case or proceeding or the commencement of any
          case against it;


                                      32

<PAGE>

               (C)  consents to the appointment of a Custodian of it or for
          any substantial part of its property;

               (D)  makes a general assignment for the benefit of its
          creditors;

               (E)  files a petition in bankruptcy or answer or consent
          seeking reorganization or relief; or

               (F)  consents to the filing of such petition or the
          appointment of or taking possession by a Custodian;

          (4)  a court of competent jurisdiction enters an order or decree
     under any Bankruptcy Law that:

               (A)  is for relief against the Company in an involuntary case
          or proceeding, or adjudicates the Company insolvent or bankrupt;

               (B)  appoints a Custodian of the Company or for any
          substantial part of its property; or

               (C)  orders the winding up or liquidation of the Company;

     and the order or decree remains unstayed and in effect for 60 days;

          (5)  the Company fails to deliver shares of Common Stock or pay
     cash in lieu thereof when such Common Stock or cash is required to be
     paid, as the case may be, following conversion of a Security; or

          (6)  a default under any mortgage, indenture, or instrument under
     which there may be issued or by which there may be secured or evidenced
     any indebtedness for money borrowed by the Company or any Consolidated
     Subsidiary, whether such indebtedness now exists or shall hereafter be
     created, which default shall have resulted in such indebtedness, in an
     aggregate principal amount exceeding $25,000,000, becoming or being
     declared due and payable prior to the date on which it would otherwise
     have become due and payable, without such indebtedness having been
     discharged, or such acceleration having been rescinded or annulled, or
     there having been deposited in trust a sum of money sufficient to
     discharge in full such indebtedness, within a period of 30 days after
     there shall have been given, by registered or certified mail, to the
     Company by the Trustee or to the Company and the Trustee by the Holders
     of at least 25% in principal amount of the Securities, a written notice
     specifying such default and requiring the


                                      33

<PAGE>

     Company to cause such indebtedness to be discharged, to cause there to
     be deposited in trust a sum sufficient to discharge in full such
     indebtedness or to cause such acceleration to be rescinded or annulled
     and stating that such notice is a "Notice of Default" hereunder.

     "BANKRUPTCY LAW" means Title 11, United States Code, or any similar
Federal or state law for the relief of debtors.

     "CUSTODIAN" means any receiver, trustee, assignee, liquidator, custodian
or similar official under any Bankruptcy Law.

     A Default under clause (2) above is not an Event of Default until the
Trustee notifies the Company, or the Holders of at least 25% in aggregate
Principal Amount of the Securities at the time outstanding notify the Company
and the Trustee, of the Default and the Company does not cure such Default
within the time specified in clause (2) above after receipt of such notice.
Any such notice must specify the Default, demand that it be remedied and
state that such notice is a "Notice of Default."

     The Company shall deliver to the Trustee, within 30 days after it
becomes aware of the occurrence thereof, written notice of any event which
with the giving of notice and the lapse of time or both would become an Event
of Default under clause (2), its status and what action the Company is taking
or proposes to take with respect thereto.

     SECTION 6.2.   ACCELERATION.  If an Event of Default (other than an
Event of Default specified in Section 6.1(3)or (4)) occurs and is continuing,
the Trustee by notice to the Company, or the Holders of at least 25% in
aggregate Principal Amount of the Securities at the time outstanding by
notice to the Company and the Trustee, may declare the Issue Price and
accrued Original Issue Discount to the date of declaration on all the
Securities to be immediately due and payable, whereupon, such Issue Price and
accrued Original Issue Discount shall be due and payable immediately,
provided that, if an Event of Default specified in Section 6.1(3) or (4)
occurs and is continuing, the Issue Price and accrued Original Issue Discount
on all the Securities to the date of the occurrence of such Event of Default
shall become and be immediately due and payable without any declaration or
other act on the part of the Trustee or any Securityholders, all of which are
hereby waived by the Company.  The Holders of a majority in aggregate
Principal Amount of the Securities at the time outstanding, by notice to the
Trustee (and without notice to any other Securityholder) may rescind an
acceleration and its consequences if the rescission would not conflict with
any judgment or decree and if all existing Events of Default have been cured
or waived except nonpayment of the Issue Price and


                                      34

<PAGE>

accrued Original Issue Discount that have become due solely as a result of
acceleration and if all amounts due to the Trustee under Section 7.7 have
been paid.  No such rescission shall affect any subsequent Default or impair
any right consequent thereto.

     SECTION 6.3.   OTHER REMEDIES.  If an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy to collect the
payment of the Issue Price and accrued Original Issue Discount on the
Securities or to enforce the performance of any provision of the Securities
or this Indenture.

     The Trustee may maintain a proceeding even if the Trustee does not
possess any of the Securities or does not produce any of the Securities in
the proceeding.  A delay or omission by the Trustee or any Securityholder in
exercising any right or remedy accruing upon an Event of Default shall not
impair the right or remedy or constitute a waiver of, or acquiescence in, the
Event of Default.  No remedy is exclusive of any other remedy.  All available
remedies are cumulative.

     SECTION 6.4.   WAIVER OF PAST DEFAULTS.  The Holders of a majority in
aggregate Principal Amount of the Securities at the time outstanding, by
notice to the Trustee (and without notice to any other Securityholder), may
waive an existing Default and its consequences except (a) an Event of Default
described in Section 6.1(1) or (5), (b) a Default in respect of a provision
that under Section 9.2 cannot be amended without the consent of each
Securityholder affected or (c) a Default under Article 11.  When a Default is
waived, it is deemed cured and shall cease to exist, but no such waiver shall
extend to any subsequent or other Default or impair any consequent right,

     SECTION 6.5.   CONTROL BY MAJORITY.  The Holders of a majority in
aggregate Principal Amount of the Securities at the time outstanding may
direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee or of exercising any trust or power conferred on the
Trustee.  However, the Trustee may refuse to follow any direction that
conflicts with law or this Indenture or that the Trustee determines in good
faith is unduly prejudicial to the rights of other Securityholders or would
involve the Trustee in personal liability unless the Trustee shall have been
provided with reasonable security or indemnity against such liability
satisfactory to the Trustee.

     SECTION 6.6.   LIMITATION ON SUITS.  A Securityholder may not pursue any
remedy with respect to this Indenture or the Securities unless:


                                      35

<PAGE>

          (1)  the Holder gives to the Trustee written notice stating that an
     Event of Default is continuing;

          (2)  the Holders of at least 25% in aggregate Principal Amount of
     the Securities at the time outstanding make a written request to the
     Trustee to pursue the remedy;

          (3)  such Holder or Holders offer to the Trustee reasonable
     security or indemnity against any loss, liability or expense
     satisfactory to the Trustee;

          (4)  the Trustee does not comply with the request within 60 days
     after receipt of the notice, the request and the offer of security or
     indemnity; and

          (5)  the Holders of a majority in aggregate Principal Amount of the
     Securities at the time outstanding do not give the Trustee a direction
     inconsistent with the request during such 60-day period.

     A Securityholder may not use this Indenture to prejudice the rights of
any other Securityholder or to obtain a preference or priority over any other
Securityholder.

     SECTION 6.7.   RIGHTS OF HOLDERS TO RECEIVE PAYMENT. Notwithstanding any
other provision of this Indenture, the right of any Holder to receive payment
of the Principal Amount, Issue Price, accrued Original Issue Discount,
Redemption Price, Purchase Price, Change in Control Purchase Price or
interest, if any, in respect of the Securities held by such Holder, on or
after the respective due dates expressed in the Securities or any Redemption
Date, and to convert the Securities in accordance with Article 11 (including
the right to receive cash in lieu of Common Stock upon conversion if the
Company has elected to pay cash with respect thereto), or to bring suit for
the enforcement of any such payment on or after such respective dates or the
right to convert, shall not be impaired or affected adversely without the
consent of each such Holder.

     SECTION 6.8.   COLLECTION SUIT BY TRUSTEE.  If an Event of Default
described in Section 6.1(1) occurs and is continuing, the Trustee may recover
judgment in its own name and as trustee of an express trust against the
Company for the whole amount owing with respect to the Securities and the
amounts provided for in Section 7.7.

     SECTION 6.9.   TRUSTEE MAY FILE PROOFS OF CLAIM.  In case of the
pendency of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition or other judicial
proceeding relative to the Company or any other obligor upon the Securities
or the property of the Company or of


                                      36

<PAGE>

such other obligor or their creditors, the Trustee (irrespective of whether
the Principal Amount, Issue Price, accrued Original Issue Discount,
Redemption Price, Purchase Price, Change in Control Purchase Price or
interest, if any, in respect of the Securities shall then be due and payable
as therein expressed or by declaration or otherwise and irrespective of
whether the Trustee shall have made any demand on the Company for the payment
of any such amount) shall be entitled and empowered, by intervention in such
proceeding or otherwise:

          (a)  to file and prove a claim for the whole amount of the
     Principal Amount, Issue Price, accrued Original Issue Discount,
     Redemption Price, Purchase Price, Change in Control Purchase Price or
     interest, if any, and to file such other papers or documents as may be
     necessary or advisable in order to have the claims of the Trustee
     (including any claim for the reasonable compensation, expenses,
     disbursements and advances of the Trustee, its agents and counsel) and
     of the Holders allowed in such judicial proceeding; and

          (b)  to collect and receive any moneys or other property payable or
     deliverable on any such claims and to distribute the same;

and any Custodian, receiver, assignee, trustee, liquidator, sequestrator or
similar official in any such judicial proceeding is hereby authorized by each
Holder to make such payments to the Trustee and, in the event that the
Trustee shall consent to the making of such payments directly to the Holders,
to pay the Trustee any amount due it for the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel,
and any other amounts due the Trustee under Section 7.7.

     Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan
of reorganization, arrangement, adjustment or composition affecting the
Securities or the rights of any Holder thereof, or to authorize the Trustee
to vote in respect of the claim of any Holder in any such proceeding.

     SECTION 6.10.  PRIORITIES.  If the Trustee collects any money pursuant
to this Article 6, it shall pay out the money in the following order:

          FIRST:  to the Trustee for amounts due under Section 7.7;

          SECOND:  to holders of Senior Indebtedness to the extent required
by Article 10;


                                      37

<PAGE>

          THIRD:  to Securityholders for amounts due and unpaid on the
Securities for the Principal Amount, Issue Price, accrued Original Issue
Discount, Redemption Price, Purchase Price, Change in Control Purchase Price
or interest, if any, as the case may be, ratably, without preference or
priority of any kind, according to such amounts due and payable on the
Securities; and

          FOURTH:  the balance, if any, to the Company.

     The Trustee may fix a record date and payment date for any payment to
Securityholders pursuant to this Section 6.10.  At least 15 days before such
record date, the Company shall mail to each Securityholder and the Trustee a
notice that states the record date, the payment date and amount to be paid.

     SECTION 6.11.  UNDERTAKING FOR COSTS.  In any suit for the enforcement
of any right or remedy under this Indenture or in any suit against the
Trustee for any action taken or omitted by it as Trustee, a court in its
discretion may require the filing by any party litigant (other than the
Trustee) in the suit of an undertaking to pay the costs of the suit, and the
court in its discretion may assess reasonable costs, including reasonable
attorneys fees, against any party litigant in the suit, having due regard to
the merits and good faith of the claims or defenses made by the party
litigant.  This Section 6.11 does not apply to a suit initiated by the
Trustee, a suit by a Holder pursuant to Section 6.7 or a suit by Holders of
more than 10% in aggregate Principal Amount of the Securities at the time
outstanding.

     SECTION 6.12.  WAIVER OF STAY, EXTENSION OR USURY LAWS.  The Company
covenants (to the extent it may lawfully do so) that it shall not at any time
insist upon, or plead, or in any manner whatsoever claim or take the benefit
or advantage of, any stay or extension law or any usury or other law,
wherever enacted, now or at any time hereafter in force, that would prohibit
or forgive the Company from paying all or any portion of the Principal
Amount, Issue Price, accrued Original Issue Discount, Redemption Price,
Purchase Price or Change in Control Purchase Price in respect of the
Securities, or any interest on any such amounts, as contemplated herein, or
that may affect the covenants or the performance of this Indenture or the
Securities; and the Company (to the extent that it may lawfully do so) hereby
expressly waives all benefit or advantage of any such law, and covenants that
it will not hinder, delay or impede the execution of any power herein granted
to the Trustee, but will suffer and permit the execution of every such power
as though no such law had been enacted.

                                       TRUSTEE

               SECTION 7.1.   DUTIES OF TRUSTEE.  (a)  If an Event of
          Default has occurred and is continuing, the Trustee shall
          exercise the rights and powers vested in it by this Indenture and
          use the same degree of care and skill in its exercise as a
          prudent man would exercise or use under the circumstances in the
          conduct of his own affairs.

               (b)  Except during the continuance of an Event of Default:

                    (1)  the Trustee need perform only those duties that
               are specifically set forth in this Indenture and no others;
               and

                    (2)  in the absence of bad faith on its part, the
               Trustee may conclusively rely, as to the truth of the
               statements and the correctness of the opinions expressed
               therein, upon certificates or opinions furnished to the
               Trustee and conforming to the requirements of this
               Indenture.  However, in the case of any such certificate or
               opinions which by any provision hereof are specifically
               required to be furnished to the Trustee, the Trustee shall
               examine the certificates and opinions to determine whether
               or not they conform to the requirements of this Indenture.

               (c)  The Trustee may not be relieved from liability for its
          own negligent action, its own negligent failure to act or its own
          willful misconduct, except that:

                    (1)  this paragraph (c) does not limit the effect of
               paragraph (b) of this Section 7.1;

                    (2)  the Trustee shall not be liable for any error of
               judgment made in good faith by a Trust Officer unless it is
               proved that the Trustee was negligent in ascertaining the
               pertinent facts; and

                    (3)  the Trustee shall not be liable with respect to
               any action it takes or omits to take in good faith in
               accordance with a direction received by it pursuant to
               Section 6.5.

               (d)  Every provision of this Indenture that in any way
          relates to the Trustee is subject to paragraphs (a), (b), (c) and
          (e) of this Section 7.1.

               (e)  The Trustee may refuse to perform any duty or exercise
          any right or power hereunder or extend or risk its own funds or


                                      39

<PAGE>

          otherwise incur any financial liability unless it receives
          indemnity satisfactory to it against any loss, liability or
          expense.

               (f)  Money held by the Trustee in trust hereunder need not
          be segregated from other funds except to the extent required by
          law.  The Trustee (acting in any capacity hereunder) shall be
          under no liability for interest on any money received by it
          hereunder except as the Trustee may otherwise have agreed in
          writing with the Company.

               SECTION 7.2.   RIGHTS OF TRUSTEE.  (a)  The Trustee may rely
          on any document believed by it to be genuine and to have been
          signed or presented by the proper person.  The Trustee need not
          investigate any fact or matter stated in the document.

               (b)  Before the Trustee acts or refrains from acting, it may
          require an Officers' Certificate or an Opinion of Counsel.  The
          Trustee shall not be liable for any action it takes or omits to
          take in good faith in reliance on such Officers Certificate or
          Opinion of Counsel.

               (c)  The Trustee may act through agents and shall not be
          responsible for the misconduct or negligence of any agent
          appointed with due care.

               (d)  Subject to the provisions of Section 7.1(c), the
          Trustee shall not be liable for any action it takes or omits to
          take in good faith which it believes to be authorized or within
          its rights or powers.

               (e)  The Trustee shall be under no obligation to exercise
          any of the rights or powers vested in it by this Indenture at the
          request or direction of any of the Holders pursuant to this
          Indenture, unless such Holders shall have offered to the Trustee
          reasonable security or indemnity against the costs, expenses and
          liabilities which might be incurred by it in compliance with such
          request or direction.

               (f)  The Trustee shall not be bound to make any
          investigation into the facts or matters stated in any resolution,
          certificate, statement, instrument, opinion, report, notice,
          request, direction, consent, order, bond, debenture, note, other
          evidence of indebtedness or other paper or document, but the
          Trustee, in its discretion, may make such further inquiry or
          investigation into such facts or matters as it may see fit, and,
          if the Trustee shall determine to make such further inquiry or
          investigation, it shall be entitled to examine the books, records
          and premises of the Company, personally or by agent or attorney.

               SECTION 7.3.   INDIVIDUAL RIGHTS OF TRUSTEE.  The Trustee in
          its individual or any other capacity may become the owner or
          pledgee of Securities and may otherwise deal with the Company or
          its Affiliates with the same rights it would have if it were not
          Trustee.  Any Paying Agent, Registrar, Conversion Agent or co-
          registrar may do the same with like rights.  However, the Trustee
          must comply with Sections 7.10 and 7.11.

               SECTION 7.4.   TRUSTEE'S DISCLAIMER.  The Trustee makes no
          representation as to the validity or adequacy of this Indenture
          or the Securities, it shall not be accountable for the Company's
          use of the proceeds from the Securities, it shall not be
          responsible for any statement in the registration statement for
          the Securities under the Securities Act or in the Indenture or
          the Securities (other than its certificate of authentication), or
          the determination as to which beneficial owners are entitled to
          receive any notices hereunder.

               SECTION 7.5.   NOTICE OF DEFAULTS.  If a Default occurs and
          is continuing and if it is known to the Trustee, the Trustee
          shall give to each Securityholder notice of the Default within 90
          days after it occurs.  Except in the case of a Default described
          in Section 6.1(1), the Trustee may withhold the notice if and so
          long as a committee of its Trust Officers in good faith
          determines that withholding the notice is in the interests of
          Securityholders.

               SECTION 7.6.   REPORTS BY TRUSTEE TO HOLDERS.  Within 60
          days after each June 15 beginning with the June 15 following the
          date of this Indenture, the Trustee shall mail to each
          Securityholder a brief report dated as of such June 15 that
          complies with TIA Section 313(a).  The Trustee also shall comply
          with TIA Section 313(b).

               A copy of each report at the time of its mailing to
          Securityholders shall be provided to the Company and shall be
          filed with the SEC and each stock exchange on which the
          Securities are listed.  The Company agrees promptly to notify the
          Trustee whenever the Securities become listed on any stock
          exchange and of any delisting thereof.

               SECTION 7.7.   COMPENSATION AND INDEMNITY.  The Company
          agrees:

                    (a)  to pay to the Trustee from time to time such
               compensation as shall have been agreed to in writing between
               the Company and the Trustee for all services rendered by it
               hereunder (which compensation shall not (to the extent
               permitted by law) be limited by any provision of law in
               regard to the compensation of a trustee of an express
               trust);


                                      41

<PAGE>

                    (b)  to reimburse the Trustee upon its request and, if
               required by the Company, submission of reasonable
               documentation for all reasonable expenses, disbursements and
               advances incurred or made by the Trustee in accordance with
               any provision of this Indenture (including the reasonable
               compensation and the expenses, advances and disbursements of
               its agents and counsel), except any such expense,
               disbursement or advance as may be attributable to its
               negligence or bad faith; and

                    (c)  to indemnify each of the Trustee or any
               predecessor Trustee for, and to hold it harmless against,
               any and all loss, liability, damage, claim or expense,
               including taxes (other than taxes based upon, measured or
               determined by the income of the Trustee), incurred without
               negligence or bad faith on its part, arising out of or in
               connection with the acceptance or administration of this
               trust, including the reasonable costs and expenses of
               defending itself against any claim or liability in
               connection with the exercise or performance of any of its
               powers or duties hereunder.

               The Trustee shall give the Company prompt notice of any
          claim or liability for which the Trustee might be entitled to
          indemnification under subparagraph (c) of this Section 7.7.  To
          secure the Company's payment obligations in this Section 7.7, the
          Trustee shall have a lien prior to the Securities on all money or
          property held or collected by the Trustee.

               The Company's payment obligations pursuant to this Section
          7.7 shall survive the discharge of this Indenture.  When the
          Trustee incurs expenses after the occurrence of a Default
          specified in Section 6.1(3) or (4), the expenses are intended to
          constitute expenses of administration under the Bankruptcy Law.
          The provisions of this Section shall survive the termination of
          this Indenture.

               SECTION 7.8.   REPLACEMENT OF TRUSTEE.  The Trustee may
          resign by so notifying the Company; PROVIDED, HOWEVER, no such
          resignation shall be effective until a successor Trustee has
          accepted its appointment pursuant to this Section 7.8.  The
          Holders of a majority in aggregate Principal Amount of the
          Securities at the time outstanding may remove the Trustee by so
          notifying the Trustee and may appoint a successor Trustee
          (subject to the consent of the Company, such consent not to be
          unreasonably withheld).  The Company shall remove the Trustee if:

                    (1)  the Trustee fails to comply with Section 7.10;

                    (2)  the Trustee is adjudged bankrupt or insolvent;


                                      42

<PAGE>

                    (3)  a receiver or other public officer takes charge of
               the Trustee or its property; or

                    (4)  the Trustee otherwise becomes incapable of acting.

               If the Trustee resigns or is removed or if a vacancy exists
          in the office of Trustee for any reason, the Company shall
          promptly appoint, by resolution of its Board of Directors, a
          successor Trustee.

               A successor Trustee shall deliver a written acceptance of
          its appointment to the retiring Trustee and to the Company.
          Thereupon the resignation or removal of the retiring Trustee shall
          become me effective, and the successor Trustee shall have all
          the rights, powers and duties of the Trustee under this
          Indenture.  The successor Trustee shall mail a notice of its
          succession to Securityholders.  The retiring Trustee shall
          promptly transfer all property held by it as Trustee to the
          successor Trustee, subject to the lien provided for in Section
          7.7.

               If a successor Trustee does not take office within 30 days
          after the retiring Trustee resigns or is removed, the retiring
          Trustee, the Company or the Holders of a majority in aggregate
          Principal Amount of the Securities at the time outstanding may
          petition any court of competent jurisdiction for the appointment
          of a successor Trustee.

               If the Trustee fails to comply with Section 7.10, any
          Securityholder may petition any court of competent jurisdiction
          for the removal of the Trustee and the appointment of a successor
          Trustee.

               SECTION 7.9.   SUCCESSOR TRUSTEE BY MERGER.  Except as
          otherwise provided in Section 7.8(4), if the Trustee consolidates
          with, merges or converts into, or transfers all or substantially
          all its corporate trust business or assets to, another
          corporation, the resulting, surviving or transferee corporation
          without any further act shall be the successor Trustee.

               SECTION 7.10.  ELIGIBILITY; DISQUALIFICATION.  The Trustee
          shall at all times satisfy the requirements of TIA Section
          310(a)(1).  The Trustee shall have a combined capital and surplus
          of at least $100,000,000 as set forth in its most recent
          published annual report of condition.  The Trustee shall comply
          with TIA Section 310(b), including the optional provision
          permitted by the second sentence of TIA Section 310(b)(9).  In
          determining whether the Trustee has conflicting interests as
          defined in TIA Section 310(b)(1), the provisions contained in the
          proviso to TIA Section 310(b)(1) shall be deemed incorporated
          herein.

               SECTION 7.11.  PREFERENTIAL COLLECTION OF CLAIMS AGAINST
          COMPANY.  The Trustee shall comply with TIA Section 311(a),
          excluding any creditor relationship listed in TIA Section 311(b).
          A Trustee who has resigned or been removed shall be subject to
          TIA Section 311(a) to the extent indicated therein.

                                DISCHARGE OF INDENTURE

               SECTION 8.1.   DISCHARGE OF LIABILITY ON SECURITIES.  When
          (i) the Company delivers to the Trustee all outstanding
          Securities (other than Securities replaced pursuant to Section
          2.7) for cancellation or (ii) all outstanding Securities have
          become due and payable and the Company deposits with the Trustee
          cash or, if expressly permitted by the terms hereof, securities
          sufficient to pay at Stated Maturity the Principal Amount of all
          outstanding Securities (other than Securities replaced pursuant
          to Section 2.7), and if in either case the Company pays all other
          sums payable hereunder by the Company (including, without
          limitation, sums payable by delivery of shares of Common Stock
          pursuant to Section 3.8), then this Indenture shall, subject to
          Section 7.7, cease to be of further effect.  The Trustee shall
          join in the execution of a document prepared by the Company
          acknowledging satisfaction and discharge of this Indenture on
          demand of the Company accompanied by an Officers' Certificate and
          Opinion of Counsel and at the cost and expense of the Company.

               SECTION 8.2.   REPAYMENT TO THE COMPANY.  The Trustee and
          the Paying Agent shall return to the Company upon written request
          any money or securities held by them for the payment of any
          amount with respect to the Securities that remains unclaimed for
          two years; PROVIDED, HOWEVER, that the Trustee or such Paying
          Agent, before being required to make any such return, may, at the
          expense of the Company, cause to be published once in THE WALL
          STREET JOURNAL or another daily newspaper of national circulation
          or mail to each such Holder notice that such money or securities
          remains unclaimed and that, after a date specified therein, which
          shall not be less than 30 days from the date of such mailing, any
          unclaimed money or securities then remaining will be returned to
          the Company.  After return to the Company, Holders entitled to
          the money or securities must look to the Company for payment as
          general creditors unless an applicable abandoned property law
          designates another person.

               SECTION 9.1.   WITHOUT CONSENT OF HOLDERS.  The Company and
          the Trustee may amend this Indenture or the Securities without
          the consent of any Securityholder:

                    (1)  to cure any ambiguity, omission, defect or
               inconsistency; PROVIDED, HOWEVER, that such amendment does
               not materially adversely affect the rights of any
               Securityholder;

                    (2)  to comply with Article 5 or Section 11.14;

                    (3)  to provide for uncertificated Securities in
               addition to certificated Securities so long as such

               purposes of the Internal Revenue Code of 1986, as amended;

                    (4)  to eliminate the Company's option to pay cash in
               lieu of delivering shares of Common Stock upon conversion of
               Securities (other than cash in lieu of fractional shares),
               except with respect to elections already made; or

                    (5)  to make any change that does not adversely affect
               the rights of any Securityholder; or

               amendment thereafter, or any requirement of the SEC in
               connection with the qualification of this Indenture under
               the TIA or any amendment thereof.

               SECTION 9.2.   WITH CONSENT OF HOLDERS.  With the written
          consent of the Holders of at least a majority in aggregate
          Principal Amount of the Securities at the time outstanding, the
          Company and the Trustee may amend this Indenture or the
          Securities.  However, without the consent of each Securityholder
          affected, an amendment or supplement to this Indenture or the
          Securities may not:

                    (1)  make any change to the Principal Amount of
               Securities whose Holders must consent to an amendment;

                    (2)  make any change to the rate of accrual in

                    (3)  reduce the Principal Amount or the Issue Price of
               or extend the Stated Maturity of any Security;

                    (4)  reduce the amount of cash payable in respect of
               conversion upon the Company's election to pay cash with

               Change in Control Purchase Price of any Security or extend
               the date on which the Purchase Price or Change in Control
               Purchase Price of any Security is payable;

                    (5)  make any Security payable in money or securities
               other than that stated in the Security;

                    (6)  make any change in Article 10 that adversely
               affects the rights of any Securityholder;

                    (7)  make any change in Section 6.4 or this Section
               9.2, except to increase any percentage referred to therein,
               or make any change in Section 6.7;

                    (8)  make any change that adversely affects the right
               to convert any Security (including the right to receive cash
               in lieu of Common Stock except as set forth in Section
               9.1(4));

                    (9)  make any change that adversely affects the right
               to require the Company to purchase the Securities in
               accordance with the terms thereof and this Indenture
               (including the right to receive cash if the Company has
               elected to pay cash upon such purchase); or

                    (10)  make any change to the provisions of this
               Indenture relating to the purchase of Securities at the
               option of the Holder pursuant to Section 3.8 or 3.9 which
               change would result in a violation of applicable federal or
               state securities laws (including positions of the SEC under
               applicable no-action letters), whether as a result of the
               exercise or performance of any rights or obligations under
               such provisions or otherwise.

               It shall not be necessary for the consent of the Holders
          under this Section 9.2 to approve the particular form of any
          proposed amendment, but it shall be sufficient if such consent
          approves the substance thereof.

               An amendment under this Section 9.2 or Section 9.1 may not
          make any change that adversely affects the rights under Article
          10 of any holder of Senior Indebtedness then outstanding unless
          the requisite holders of such Senior Indebtedness consent to such
          change pursuant to the terms of such Senior Indebtedness.

               After an amendment under this Section 9.2 becomes effective,
          the Company shall mail to each Holder a notice briefly describing
          the amendment.

               SECTION 9.3.   COMPLIANCE WITH TRUST INDENTURE ACT.  Every
          supplemental indenture executed pursuant to this Article shall
          comply with the TIA as then in effect.

               SECTION 9.4.   REVOCATION AND EFFECT OF CONSENTS, WAIVERS
          AND ACTIONS.  Until an amendment or waiver becomes effective,
          consent to it or any other action by a Holder of a Security
          hereunder is a continuing consent by the Holder and every
          subsequent Holder of that Security or portion of the Security
          that evidences the same obligation as the consenting Holder's
          Security, even if notation of the consent, waiver or action is
          not made on the Security.  However, any such Holder or subsequent
          Holder may revoke the consent, waiver or action as to such
          Holder's Security or portion of the Security if the Trustee
          receives the notice of revocation before the date the amendment,
          waiver or action becomes effective.  After an amendment, waiver
          or action becomes effective, it shall bind every Securityholder,
          except as provided in Section 9.2.

               SECTION 9.5.   NOTATION ON OR EXCHANGE OF SECURITIES.  If an
          amendment changes the terms of a Security, the Trustee may
          require the Holder of the Security to deliver it to the Trustee.
          The Trustee may place an appropriate notation on the Security
          regarding the changed terms and return it to the Holder.
          Alternatively, if the Company or the Trustee so determines, the
          Company in exchange for the Security shall issue and the Trustee
          shall authenticate a new Security that reflects the changed
          terms.

               SECTION 9.6.   TRUSTEE TO SIGN SUPPLEMENTAL INDENTURES.  The
          Trustee shall sign any supplemental indenture authorized pursuant
          to this Article 9 if the amendment does not adversely affect the
          rights, duties, liabilities or immunities of the Trustee.  If it
          does, the Trustee may, but need not, sign it.  In signing such
          amendment the Trustee shall be entitled to receive, and (subject
          to the provisions of Section 7.1) shall be fully protected in
          relying upon, an Officers' Certificate and an Opinion of Counsel
          stating that such amendment is authorized or permitted by this
          Indenture.

               SECTION 9.7.   EFFECT OF SUPPLEMENTAL INDENTURES.  Upon the
          execution of any supplemental indenture under this Article, this
          Indenture shall be modified in accordance therewith, and such
          supplemental indenture shall form a part of this Indenture for
          all purposes; and every Holder of Securities theretofore or
          thereafter authenticated and delivered hereunder shall be bound
          thereby.

          of creditors or any other marshalling of assets and liabilities
          of the Company, then and in any such event the holders of Senior

          amounts due or to become due on or in respect of all Senior
          Indebtedness, or provision shall be made for such payment in

          of this Section, the Trustee or the Holder of any Security shall
          have received any payment or distribution of assets of the
          Company of any kind or character, whether in cash, property or
          securities, including any such payment or distribution which may

          indebtedness of the Company being subordinated to the payment of
          the Securities, before all Senior Indebtedness is paid in full or
          payment thereof provided for, and if such fact shall, at or prior
          to the time of such payment or distribution, have been made known

          liquidating trustee, Custodian, assignee, agent or other Person
          making payment or distribution of assets of the Company for
          application to the payment of all Senior Indebtedness remaining
          unpaid, to the extent necessary to pay all Senior Indebtedness in
          full, after giving effect to any concurrent payment or
          distribution to or for the holders of Senior Indebtedness.

               The consolidation of the Company with, or the merger of the

          which acquires by conveyance or transfer such properties and

          the time such Securities so become due and payable shall be
          entitled to receive payment in full of all amounts due or to
          become due on or in respect of all Senior Indebtedness, or

          Securities or on account of the purchase or other acquisition of

               In the event that, notwithstanding the foregoing, the
          Company shall make any payment to the Trustee or the Holder of
          any Security prohibited by the foregoing provisions of this
          Section, and if such fact shall, at or prior to the time of such

          payment with respect to which Section 10.2 would be applicable.

               SECTION 10.4.  NO PAYMENT WHEN SENIOR INDEBTEDNESS IN
          DEFAULT.  In the event and during the continuation of any default

          with respect thereto, or in the event that any event of default
          with respect to any Senior Indebtedness shall have occurred and
          be continuing, permitting the holders of such Senior Indebtedness
          (or a trustee on behalf of the holders thereof) to declare such
          Senior Indebtedness due and payable prior to the date on which it
          would otherwise have become due and payable, unless and until
          such event of default shall have been cured or waived or shall
          have ceased to exist and such acceleration shall have been
          rescinded or annulled, or in the event any judicial proceeding
          shall be pending with respect to any such default, then no
          payment (including any payment which may be payable by reason of
          the payment of any other indebtedness of the Company being

          Company shall make any payment to the Trustee or the Holder of
          any Security prohibited by the foregoing provisions of this
          Section, and if such fact shall then have been made known to the
          Trustee or, as the case may be, such Holder, then and in such
          event such payment shall be paid over and delivered forthwith to
          the Company.

          Control Purchase Price or interest, if any, as the case may be,

          the Holders of the Securities, if, at the time of such
          application by the Trustee, the Trustee did not have actual
          knowledge that such payment would have been prohibited by the
          provisions of this Article.

          to the extent of the payments or distributions made to the
          holders of such Senior Indebtedness pursuant to the provisions of
          this Article (equally and ratably with the holders of all
          indebtedness of the Company which by its express terms is
          subordinated to indebtedness of the Company to substantially the
          same extent as the Securities are subordinated and is entitled to
          like rights of subrogation) to the rights of the holders of such

          payments over pursuant to the provisions of this Article to the
          holders of Senior Indebtedness by Holders of the Securities or
          the Trustee, shall, as among the Company, its creditors other
          than holders of Senior Indebtedness and the Holders of the
          Securities, be deemed to be a payment or distribution by the
          Company to or on account of the Senior Indebtedness.

          The provisions of this Article are and are intended solely for
          the purpose of defining the relative rights of the Holders of the
          Securities, on the one hand, and the holders of Senior
          Indebtedness, on the other hand.  Nothing contained in this
          Article or elsewhere in this Indenture or in the Securities is
          intended to or shall (a) impair, as among the Company, its
          creditors other than holders of Senior Indebtedness and the
          Holders of the Securities, the obligation of the Company, which
          is absolute and unconditional (and which, subject to the rights
          under this Article of the holders of Senior Indebtedness, is

          or (b) affect the relative rights against the Company of the
          Holders of the Securities and creditors of the Company other than
          the holders of Senior Indebtedness; or (c) prevent the Trustee or
          the Holder of any Security from exercising all remedies otherwise
          permitted by applicable law upon default under this Indenture,
          subject to the rights, if any, under this Article of the holders
          of Senior Indebtedness to receive cash, property and securities
          otherwise payable or deliverable to the Trustee or such Holder.

               SECTION 10.8.  TRUSTEE TO EFFECTUATE SUBORDINATION.  Each
          Holder of a Security by his acceptance thereof authorizes and
          directs the Trustee on his behalf to take such action as may be
          necessary or appropriate to effectuate the subordination provided
          in this Article and appoints the Trustee his attorney-in-fact for
          any and all such purposes.

               SECTION 10.9.  NO WAIVER OF SUBORDINATION PROVISIONS.  No
          right of any present or future holder of any Senior Indebtedness
          to enforce subordination as herein provided shall at any time in
          any way be prejudiced or impaired by any act or failure to act on
          the part of the Company or by any act or failure to act, in good
          faith, by any such holder, or by any non-compliance by the
          Company with the terms, provisions and covenants of this
          Indenture, regardless of any knowledge thereof any such holder
          may have or be otherwise charged with.

               Without in any way limiting the generality of the foregoing
          paragraph, the holders of Senior Indebtedness may, at any time
          and from time to time, without the consent of or notice to the
          Trustee or the Holders of the Securities, without incurring
          responsibility to the Holders of the Securities and without
          impairing or releasing the subordination provided in this Article
          or the obligations hereunder of the Holders of the Securities to
          the holders of Senior Indebtedness, do any one or more of the
          following:  (i) change the manner, place or terms of payment or
          extend the time of payment of, or renew or alter, Senior
          Indebtedness, or otherwise amend or supplement in any manner
          Senior Indebtedness or any instrument evidencing the same or any
          agreement under which Senior Indebtedness is outstanding; (ii)
          sell, exchange, release or otherwise deal with any property
          pledged, mortgaged or otherwise securing Senior Indebtedness;
          (iii) release any Person liable in any manner for the collection
          of Senior Indebtedness; and (iv) exercise or refrain from
          exercising any rights against the Company and any other Person.

               SECTION 10.10.  NOTICE TO TRUSTEE. The Company shall give
          prompt written notice to the Trustee of any fact known to the
          Company which would prohibit the making of any payment to or by
          the Trustee in respect of the Securities.  Notwithstanding the
          provisions of this Article or any other provision of this
          Indenture, the Trustee shall not be charged with knowledge of the
          existence of any facts which would prohibit the making of any
          payment to or by the Trustee in respect of the Securities, unless
          and until the Trustee shall have received written notice thereof
          from the Company or a holder of Senior Indebtedness or from any
          trustee therefor; and, prior to the receipt of any such written
          notice, the Trustee, subject to the provisions of Section 7.1,
          shall be entitled in all respects to assume that no such facts
          exist.

               Subject to the provision of Section 7.1, the Trustee shall
          be entitled to rely on the delivery to it of a written notice by
          a person representing himself to be a holder of Senior
          Indebtedness (or a trustee therefor) to establish that such
          notice has been given by a holder of Senior Indebtedness (or a
          trustee therefor).  In the event that the Trustee determines in
          good faith that further evidence required with respect to the
          right of any person as a holder of Senior Indebtedness to
          participate in any payment or distribution pursuant to this
          Article, the Trustee may request such person to furnish evidence
          to the reasonable satisfaction of the Trustee as to the amount of
          Senior Indebtedness held by such person, the extent to which such
          person is entitled to participate in such payment or distribution
          and any other facts pertinent to the rights of such person under
          this Article, and if such evidence is not furnished, the Trustee
          may defer any payment to such Person pending judicial
          determination as to the right of such Person to receive such
          payment.

               SECTION 10.11.  RELIANCE ON JUDICIAL ORDER OR CERTIFICATE OF
          LIQUIDATING AGENT.  Upon any payment or distribution of assets of
          the Company referred to in this Article, the Trustee, subject to
          the provisions of Section 7.1, and the Holders of the Securities
          shall be entitled to rely upon any order or decree entered by any
          court of competent jurisdiction in which such insolvency,
          bankruptcy, receivership, liquidation, reorganization,
          dissolution, winding up or similar case or proceeding is pending,
          or a certificate of the trustee in bankruptcy, liquidating
          trustee, Custodian, receiver, assignee for the benefit of
          creditors, agent or other Person making such payment or
          distribution, delivered to the Trustee or to the Holders of
          Securities, for the purpose of ascertaining the persons entitled
          to participate in such payment or distribution, the holders of
          the Senior Indebtedness and other indebtedness of the Company,
          the amount thereof or payable thereon, the amount or amounts paid


                                      53


<PAGE>

          or distributed thereon and all other facts pertinent thereto or
          to this Article.

               SECTION 10.12.  TRUSTEE NOT FIDUCIARY FOR HOLDERS OF SENIOR
          INDEBTEDNESS.  The Trustee shall not be deemed to owe any
          fiduciary duty to the holders of Senior Indebtedness and shall
          not be liable to any such holders if it shall in good faith
          mistakenly pay over or distribute to Holders of Securities or to
          the Company or to any other person cash, property or securities
          to which any holders of Senior Indebtedness shall be entitled by
          virtue of this Article or otherwise.

               SECTION 10.13.  RIGHTS OF TRUSTEE AS HOLDER OF SENIOR
          INDEBTEDNESS; PRESERVATION OF TRUSTEE'S RIGHTS.  The Trustee in
          its individual capacity shall be entitled to all the rights set
          forth in this Article with respect to any Senior Indebtedness
          which may at any time be held by it, to the same extent as any
          other holder of Senior Indebtedness, and nothing in this
          Indenture shall deprive the Trustee of any of its rights as such
          holder.

               Nothing in this Article shall apply to claims of, or
          payments to, the Trustee under or pursuant to Section 7.7.

               SECTION 10.14.  ARTICLE APPLICABLE TO PAYING AGENTS.  In
          case at any time any Paying Agent other than the Trustee shall
          have been appointed by the Company and be then acting hereunder,
          the term "Trustee" as used in this Article shall in such case
          (unless the context otherwise requires) be construed as extending
          to and including such Paying Agent within its meaning as fully
          for all intents and purposes as if such Paying Agent were named
          in this Article in addition to or in place of the Trustee;
          PROVIDED, HOWEVER, that Sections 10.10 and 10.12 shall not apply
          to the Company or any Affiliate of the Company if it or such
          Affiliate acts as Paying Agent.

               SECTION 10.15.  CERTAIN CONVERSIONS DEEMED PAYMENT.  For the
          purposes of this Article only, (1) the issuance and delivery of
          junior securities upon conversion of Securities in accordance
          with Article 11 shall not be deemed to constitute a payment or
          distribution on account of the Principal Amount, Issue Price,
          accrued Original Issue Discount, Redemption Price, Purchase
          Price, Change in Control Purchase Price, or interest, if any, as
          the case may be, in respect of Securities or on account of the
          purchase or other acquisition of Securities, and (2) the payment,
          issuance or delivery of cash, property or securities (other than
          junior securities) upon conversion of a Security shall be deemed
          to constitute payment on account of principal of such Security.
          For the purposes of this Section, the term "junior securities"
          means (a) shares of any stock of any class of the Company and (b)
          securities of the Company which are subordinated in right of


                                      54

<PAGE>

          payment to all Senior Indebtedness which may be outstanding at
          the time of issuance or delivery of such securities to the same
          extent as, or to a greater extent than, the Securities are so
          subordinated as provided in this Article.  Nothing contained in
          this Article or elsewhere in this Indenture or in the Securities
          is intended to or shall impair, as among the Company, its
          creditors other than holders of Senior Indebtedness and the
          Holders of the Securities, the right, which is absolute and
          unconditional, of the Holder of any Security to convert such
          Security in accordance with Article 11.


                                      ARTICLE 11

                                      CONVERSION

               SECTION 11.1.  CONVERSION PRIVILEGE.  A Holder of a Security
          may convert such Security into Common Stock at any time during
          the period stated in paragraph 9 of the Securities.  The number
          of shares of Common Stock issuable upon conversion of a Security
          per $1,000 of Principal Amount thereof (the "CONVERSION RATE")
          shall be that set forth in paragraph 9 in the Securities, subject
          to adjustment as herein set forth.  The Holders' right to convert
          Securities into Common Stock is subject to the Company's right to
          elect to instead pay such Holder the amount of cash set forth in
          the next succeeding sentence, in lieu of delivering such shares
          of Common Stock; PROVIDED, HOWEVER, that if such payment of cash
          is not allowed pursuant to the provisions of this Indenture or
          otherwise, the Company shall deliver shares of Common Stock (and
          cash in lieu of fractional shares of Common Stock) in accordance
          with this Article 11, whether or not the Company has delivered
          its notice of whether such Security shall be converted into
          Common Stock or cash pursuant to Section 11.2.  The amount of
          cash to be paid per $1,000 Principal Amount of a Security upon
          conversion shall be equal to the Sale Price of a share of Common
          Stock on the Trading Day immediately prior to the related
          Conversion Date multiplied by the Conversion Rate in effect on
          such Trading Day.

               The Company shall not pay cash in lieu of delivering shares
          of Common Stock upon the conversion of any Security pursuant to
          the terms of this Article 11 (other than cash in lieu of
          fractional shares pursuant to Section 11.3) if there has occurred
          (prior to, on or after, as the case may be, the Conversion Date
          or the date on which the Company delivers its notice of whether
          such Security shall be converted into Common Stock or cash
          pursuant to Section 11.2) and is continuing an Event of Default
          (other than a default in such payment on such Securities).

               A Holder may convert a portion of the Principal Amount of a
          Security if the portion is $1,000 or an integral multiple of


                                      55

<PAGE>

          $1,000.  Provisions of this Indenture that apply to conversion of
          all of a Security also apply to conversion of a portion of a
          Security.

               "AVERAGE SALE PRICE" means the average of the Sale Prices of
          the Common Stock for the shorter of:

                    (i)  30 consecutive Trading Days ending on the last
               full Trading Day prior to the Time of Determination with
               respect to the rights, options, warrants or distribution in
               respect of which the Average Sale Price is being calculated,
               or

                    (ii)  the period (x) commencing on the date next
               succeeding the first public announcement of (a) the issuance
               of rights, options or warrants or (b) the distribution, in
               each case, in respect of which the Average Sale Price is
               being calculated and (y) proceeding through the last full
               trading day prior to the Time of Determination with respect
               to the rights, warrants or distribution in respect of which
               the Average Sale Price is being calculated, or

                    (iii)  the period, if any, (x) commencing on the date
               next succeeding the Ex-Dividend Time with respect to the
               next preceding (a) issuance of rights, warrants, or options
               or (b) distribution, in each case, for which an adjustment
               is required by the provisions of Section 11.6(4), 11.7 or
               11.8 and (y) proceeding through the last full Trading Day
               prior to the Time of Determination with respect to the
               rights, warrants, or options or distribution in respect of
               which the Average Sale Price is being calculated.

                    If the Ex-Dividend Time (or in the case of a
               subdivision, combination or reclassification, the effective
               date with respect thereto) with respect to a dividend,
               subdivision, combination or reclassification to which
               Section 11.6(l), (2), (3) or (5) applies occurs during the
               period applicable for calculating "Average Sale Price"
               pursuant to the definition in the preceding sentence,
               "Average Sale Price" shall be calculated for such period in
               a manner determined by the Board of Directors to reflect the
               impact of such dividend, subdivision, combination or
               reclassification on the Sale Price of the Common Stock
               during such period.

               "TIME OF DETERMINATION" means the time and date of the
          earlier of (i) the determination of stockholders entitled to
          receive rights, warrants, or options or a distribution, in each
          case, to which Sections 11.6(4), 11.7 and 11.8 apply and (ii) the
          time ("EX-DIVIDEND TIME") immediately prior to the commencement
          of "ex-dividend" trading for such rights, options, warrants or


                                      56

<PAGE>

          distribution on the New York Stock Exchange or such other
          national or regional exchange or market on which the Common Stock
          is then listed or quoted.

               SECTION 11.2.  CONVERSION PROCEDURE.  To convert a Security
          a Holder must satisfy the requirements in paragraph 9 of the
          Securities.  The date on which the Holder satisfies all those
          requirements is the conversion date (the "CONVERSION DATE").
          Within two Business Days following the Conversion Date, the
          Company shall deliver to the Holder, through the Conversion
          Agent, written notice of whether such Security shall be converted
          into Common Stock or cash.  If the Company shall have notified
          the Holder that such Security shall be converted into Common
          Stock, the Company shall deliver to the Holder no later than the
          seventh Business Day following the Conversion Date, through the
          Conversion Agent, a certificate for the number of full shares of
          Common Stock issuable upon the conversion and cash in lieu of any
          fractional share determined pursuant to Section 11.3.  Except as
          provided in Section 11.1, if the Company shall have notified the
          Holder that such Security shall be converted into cash, the
          Company shall deliver to the Holder surrendering such Security
          the amount of cash payable upon such conversion on the fifth
          Business Day following such Conversion Date.  Except as provided
          in Section 11.1, the Company may not change its election with
          respect to the consideration to be delivered upon conversion of a
          Security once the Company has notified the Holder in accordance
          with this paragraph.

               The person in whose name the certificate is registered shall
          be treated as a stockholder of record on and after the Conversion
          Date; PROVIDED, HOWEVER, that no surrender of a Security on any
          date when the stock transfer books of the Company shall be closed
          shall be effective to constitute the person or persons entitled
          to receive the shares of Common Stock upon such conversion as the
          record holder or holders of such shares of Common Stock on such
          date, but such surrender shall be effective to constitute the
          person or persons entitled to receive such shares of Common Stock
          as the record holder or holders thereof for all purposes at the
          close of business on the next succeeding day on which such stock
          transfer books are open; PROVIDED, HOWEVER, that such conversion
          shall be at the Conversion Rate in effect on the date that such
          Security shall have been surrendered for conversion, as if the
          stock transfer books of the Company had not been closed.  Upon
          conversion of a Security, such person shall no longer be a Holder
          of such Security.

               Holders may surrender a Security for conversion by means of
          book entry delivery in accordance with paragraph 9 of the
          Securities and the regulations of the applicable book entry
          facility.


                                      57

<PAGE>

               No payment or adjustment will be made for dividends on any
          Common Stock except as provided in this Article 11.  On
          conversion of a Security, that portion of accrued Original Issue
          Discount attributable to the period from the Issue Date of the
          Security to the Conversion Date with respect to the converted
          Security shall not be cancelled, extinguished or forfeited, but
          rather shall be deemed to be paid in full to the Holder thereof
          through delivery of the Common Stock (together with the cash
          payment, if any, in lieu of fractional shares) or of cash, as the
          case may be, in exchange for the Security being converted
          pursuant to the provisions hereof.

               If the Holder converts more than one Security at the same
          time, the number of shares of Common Stock issuable or the amount
          of cash to be paid, as the case may be, upon the conversion shall
          be computed based on the total Principal Amount of the Securities
          converted.

               Upon surrender of a Security that is converted in part, the
          Company shall execute, and the Trustee shall authenticate and
          deliver to the Holder, a new Security in an authorized
          denomination equal in Principal Amount to the unconverted portion
          of the Security surrendered.

               If the last day on which a Security may be converted is a
          Legal Holiday in a place where a Conversion Agent is located, the
          Security may be surrendered to that Conversion Agent on the next
          succeeding day that is not a Legal Holiday.

               SECTION 11.3.  FRACTIONAL SHARES.  The Company will not
          issue a fractional share of Common Stock upon conversion of a
          Security.  Instead, the Company will deliver cash for the current
          market value of the fractional share.  The current market value
          of a fractional share shall be determined to the nearest 1/1000th
          of a share by multiplying the Sale Price, on the last Trading Day
          prior to the Conversion Date, of a full share by the fractional
          amount and rounding the product to the nearest whole cent.

               SECTION 11.4.  TAXES ON CONVERSION.  If a Holder converts a
          Security, the Company shall pay any documentary, stamp or similar
          issue or transfer tax due on the issue of shares of Common Stock
          upon such conversion.  However, the Holder shall pay any such tax
          which is due because the Holder requests the shares to be issued
          in a name other than the Holder's name.  The Conversion Agent may
          refuse to deliver the certificates representing the Common Stock
          being issued in a name other than the Holder's name until the
          Conversion Agent receives a sum sufficient to pay any tax which
          will be due because the shares are to be issued in a name other
          than the Holder's name.  Nothing herein shall preclude any tax
          withholding required by law or regulations.

               SECTION 11.5.  COMPANY TO PROVIDE STOCK.  The Company shall,
          prior to issuance of any Securities hereunder, and from time to
          time as may be necessary, reserve out of its authorized but
          unissued Common Stock a sufficient number of shares of Common
          Stock to permit the conversion of the Securities for shares of
          Common Stock.

               All shares of Common Stock delivered upon conversion of the
          Securities shall be newly issued shares or treasury shares, shall
          be duly and validly issued and fully paid and nonassessable and
          shall be free from preemptive rights and free of any lien or
          adverse claim.

               The Company will endeavor promptly to comply with all
          federal and state securities laws regulating the offer and
          delivery of shares of Common Stock upon conversion of Securities,
          if any, and will list or cause to have quoted such shares of
          Common Stock on each national securities exchange or in the over-
          the-counter market or such other market on which the Common Stock
          is then listed or quoted.

               SECTION 11.6.  ADJUSTMENT FOR CHANGE IN CAPITAL STOCK.  If,
          after the Issue Date, the Company:

                    (1)  pays a dividend or makes a distribution on its
               Common Stock in shares of its Common Stock;

                    (2)  subdivides its outstanding shares of Common Stock
               into a greater number of shares;

                    (3)  combines its outstanding shares of Common Stock
               into a smaller number of shares;

                    (4)  pays a dividend or makes a distribution on its
               Common Stock in shares of its Capital Stock (other than
               Common Stock or rights, warrants or options for its Capital
               Stock); or

                    (5)  issues by reclassification of its Common Stock any
               shares of its Capital Stock (other than rights, warrants or
               options for its Capital Stock),

          then the conversion privilege and the Conversion Rate in effect
          immediately prior to such action shall be adjusted so that the
          Holder of a Security thereafter converted may receive the number
          of shares or other units of Capital Stock of the Company which
          such Holder would have owned immediately following such action if
          such Holder had converted the Security immediately prior to such
          action.


                                      59

<PAGE>

               The adjustment shall become effective immediately after the
          record date in the case of a dividend or distribution and
          immediately after the effective date in the case of a
          subdivision, combination or reclassification.

               If after an adjustment a Holder of a Security upon
          conversion of such Security may receive shares or other units of
          two or more classes or series of Capital Stock of the Company,
          the Conversion Rate shall thereafter be subject to adjustment
          upon the occurrence of an action taken with respect to any such
          class or series of Capital Stock as is contemplated by this
          Article 11 with respect to the Common Stock, on terms comparable
          to those applicable to Common Stock in this Article 11.

               SECTION 11.7.  ADJUSTMENT FOR RIGHTS ISSUE.  If, after the
          Issue Date, the Company distributes any rights, warrants or
          options to all holders of its Common Stock entitling them, for a
          period expiring within 60 days after the record date for such
          distribution, to purchase shares of Common Stock at a price per
          share less than the Sale Price as of the Time of Determination,
          the Conversion Rate shall be adjusted in accordance with the
          formula:

                                           O + N
                                       --------------
                         R' = O + R  x
                                       O + (N x P)
                                           -------
                                              M
          where:

               R' = the adjusted Conversion Rate.

               R  = the current Conversion Rate.

               O  = the number of shares of Common Stock outstanding on the
                    record date for the distribution to which this Section
                    11.7 is being applied.

               N  = the number of additional shares of Common Stock offered
                    pursuant to the distribution.

               P  = the offering price per share of such additional shares.

               M  = the Average Sale Price, MINUS, in the case of (i) a
                    distribution to which Section 11.6(4) applies or (ii) a
                    distribution to which Section 11.8 applies, for which,
                    in each case, (x) the record date shall occur on or
                    before the record date for the distribution to which
                    this Section 11.7 applies and (y) the Ex-Dividend Time
                    shall occur on or after the date of the Time of
                    Determination for the distribution to which this
                    Section 11.7 applies, the fair market value (on the

<PAGE>

                    record date for the distribution to which this Section
                    11.7 applies) of (1) the Capital Stock of the Company
                    distributed in respect of each share of Common Stock in
                    such Section 11.6(4) distribution, and (2) the assets
                    of the Company or debt securities or any rights,
                    warrants or options to purchase securities of the
                    Company distributed in respect of each share of Common
                    Stock in such Section 11.8 distribution.

          The Board of Directors shall determine fair market values for the
          purposes of this Section 11.7.

               The adjustment shall become effective immediately after the
          record date for the determination of shareholders entitled to
          receive the rights, warrants or options to which this Section
          11.7 applies.

               No adjustment shall be made under this Section 11.7 if the
          application of the formula stated above in this Section 11.7
          would result in value of R' that is equal to or less than the
          value of R.

               SECTION 11.8.  ADJUSTMENT FOR OTHER DISTRIBUTIONS.  If,
          after the Issue Date, the Company distributes to all holders of
          its Common Stock any of its assets or debt securities or any
          rights, warrants or options to purchase securities of the Company
          (including securities or cash, but excluding (x) distributions of
          Capital Stock referred to in Section 11.6 and distributions of
          rights, warrants or options referred to in Section 11.7 and (y)
          cash dividends or other cash distributions that are paid out of
          consolidated current net earnings or earnings retained in the
          business as shown on the books of the Company unless such cash
          dividends or other cash distributions are Extraordinary Cash
          Dividends (as defined below)) the Conversion Rate shall be
          adjusted, subject to the provisions of the last paragraph of this
          Section 11.8, in accordance with the formula:

                                                M
                                             -------
                                   R' =  R x
                                              M-F


          where:

               R' = the adjusted Conversion Rate.

               R  = the current Conversion Rate.

               M  = the Average Sale Price, MINUS, in the case of a
                    distribution to which Section 11.6(4) applies, for
                    which (i) the record date shall occur on or before the

<PAGE>

                    record date for the distribution to which this Section
                    11.8 applies and (ii) the Ex-Dividend Time shall occur
                    on or after the date of the Time of Determination for
                    the distribution to which this Section 11.8 applies,
                    the fair market value (on the record date for the
                    distribution to which this Section 11.8 applies) of any
                    Capital Stock of the Company distributed in respect of
                    each share of Common Stock in such Section 11.6(4)
                    distribution.

               F  = the fair market value (on the record date for the
                    distribution to which this Section 11.8 applies) of the
                    assets, securities, rights, warrants or options to be
                    distributed in respect of each share of Common Stock in
                    the distribution to which this Section 11.8 is being
                    applied (including, in the case of cash dividends or
                    other cash distributions giving rise to an adjustment,
                    all such cash distributed concurrently).

          The Board of Directors shall determine fair market values for the
          purpose of this Section 11.8.

               The adjustment shall become effective immediately after the
          record date for the determination of shareholders entitled to
          receive the distribution to which this Section 11.8 applies.

               For purposes of this Section 11.8, the term "EXTRAORDINARY
          CASH DIVIDEND" shall mean any cash dividend with respect to the
          Common Stock the amount of which, together with the aggregate
          amount of cash dividends on the Common Stock to be aggregated
          with such cash dividend in accordance with the provisions of this
          paragraph, equals or exceeds the threshold percentages set forth
          in items (i) or (ii) below:

                    (i)  If, upon the date prior to the Ex-Dividend Time
               with respect to a cash dividend on the Common Stock, the
               aggregate amount of such cash dividend together with the
               amounts of all cash dividends on the Common Stock with Ex-
               Dividend Times occurring in the eighty-five (85) consecutive
               day period ending on the date prior to the Ex-Dividend Time,
               with respect to the cash dividend to which this provision is
               being applied equals or exceeds twelve and one-half percent
               (12.5%) of the average of the Sale Prices during the period
               beginning on the date after the first such Ex-Dividend Time
               in such period and ending on the date prior to the Ex-
               Dividend Time with respect to the cash dividend to which
               this provision is being applied (except that if no other
               cash dividend has had an Ex-Dividend Time occurring in such
               period, the period for calculating the average of the Sale
               Prices shall be the period commencing eighty-five (85) days
               prior to the date prior to the Ex-Dividend Time with respect


                                      62

               to the cash dividend to which this provision is being
               applied), such cash dividend together with each other cash
               dividend with an Ex-Dividend Time occurring in such eighty-
               five (85) day period shall be deemed to be an Extraordinary
               Cash Dividend and for purposes of applying the formula set
               forth above in this Section 11.8, the value of "F" shall be
               equal to (w) the aggregate amount of such cash dividend
               together with the amounts of the other cash dividends with
               Ex-Dividend Times occurring in such period MINUS (x) the
               aggregate amount of such other cash dividends with Ex-
               Dividend Times occurring in such period for which a prior
               adjustment in the Conversion Rate was previously made under
               this Section 11.8.

                    (ii)  If upon the date prior to the Ex-Dividend Time
               with respect to a cash dividend on the Common Stock, the
               aggregate amount of such cash dividend together with the
               amounts of all cash dividends on the Common Stock with Ex-
               Dividend Times occurring in the three-hundred-sixty-five
               (365) consecutive day period ending on the date prior to the
               Ex-Dividend Time with respect to the cash dividend to which
               this provision is being applied equals or exceeds twenty-
               five percent (25%) of the average of the Sale Prices during
               the period beginning on the date after the first such Ex-
               Dividend Time in such period and ending on the date prior to
               the Ex-Dividend Time with respect to the cash dividend to
               which this provision is being applied (except that if no
               other cash dividend has had an Ex-Dividend Time occurring in
               such period, the period for calculating the average of the
               Sale Prices shall be the period commencing three-hundred-
               sixty-five (365) days prior to the date prior to the Ex-
               Dividend Time with respect to the cash dividend to which
               this provision is being applied), such cash dividend
               together with each other cash dividend with an Ex-Dividend
               Time occurring in such three-hundred-sixty-five (365) day
               period shall be deemed to be an Extraordinary Cash Dividend
               and for purposes of applying the formula set forth above in
               this Section 11.8, the value of "F" shall be equal to (y)
               the aggregate amount of such cash dividend together with
               amounts of the other cash dividends with Ex-Dividend Times
               occurring in such period MINUS (z) the aggregate amount of
               such other cash dividends with Ex-Dividend Times occurring
               in such period for which a prior adjustment in the
               Conversion Rate was previously made under this Section 11.8.

               In the event that, with respect to any distribution to which
          this Section 11.8 would otherwise apply, the difference "M-F" as
          defined in the above formula is less than $1.00 or "F" is greater
          than "M", then the adjustment provided by this Section 11.8 shall
          not be made and in lieu thereof the provisions of Section 11.14
          shall apply to such distribution.

               SECTION 11.9.  WHEN ADJUSTMENT MAY BE DEFERRED.  No
          adjustment in the Conversion Rate need be made unless the
          adjustment would require an increase or decrease of at least 1%
          in the Conversion Rate.  Any adjustments that are not made shall
          be carried forward and taken into account in any subsequent
          adjustment.

               All calculations under this Article 11 shall be made to the
          nearest cent or to the nearest 1/1,000th of a share, as the case
          may be, with one-half of a cent and 5/10,000 of a share being
          rounded upwards.

               SECTION 11.10.  WHEN NO ADJUSTMENT REQUIRED.  No adjustment
          need be made for a transaction referred to in Section 11.6, 11.7,
          11.8 or 11.14 if Securityholders are to participate in the
          transaction on a basis and with notice that the Board of
          Directors determines to be fair and appropriate in light of the
          basis and notice on which holders of Common Stock participate in
          the transaction.

               No adjustment need be made for rights to purchase Common
          Stock pursuant to a Company plan for reinvestment of dividends or
          interest.

               No adjustment need be made for a change in the par value or
          no par value of the Common Stock.

               To the extent the Securities become convertible into cash
          pursuant to the terms of Section 11.6, 11.7, 11.8 or 11.14, no
          adjustment need be made thereafter as to the cash.  Interest will
          not accrue on the cash.

               SECTION 11.11.  NOTICE OF ADJUSTMENT.  Whenever the
          Conversion Rate is adjusted, the Company shall promptly mail to
          Securityholders a notice of the adjustment.  The Company shall
          file with the Trustee and the Conversion Agent such notice and a
          certificate from the Company's independent public accountants
          briefly stating the facts requiring the adjustment and the manner
          of computing it.  The certificate shall be conclusive evidence
          that the adjustment is correct.  Neither the Trustee nor any
          Conversion Agent shall be under any duty or responsibility with
          respect to any such certificate except to exhibit the same to any
          Holder desiring inspection thereof.

               SECTION 11.12.  VOLUNTARY INCREASE.  The Company from time
          to time may increase the Conversion Rate by any amount and for
          any period of time (PROVIDED, that such period is not less than
          20 Business Days).  Whenever the Conversion Rate is increased,
          the Company shall mail to Securityholders and file with the
          Trustee and the Conversion Agent a notice of the increase.  The
          Company shall mail the notice at least 15 days before the date


                                      64

<PAGE>

          the increased Conversion Rate takes effect.  The notice shall
          state the increased Conversion Rate and the period it will be in
          effect.

               A voluntary increase of the Conversion Rate does not change
          or adjust the Conversion Rate otherwise in effect for purposes of
          Sections 11.6, 11.7 or 11.8.

               SECTION 11.13.  NOTICE OF CERTAIN TRANSACTIONS.  If:

                    (1)  the Company takes any action that would require an
               adjustment in the Conversion Rate pursuant to Section 11.6,
               11.7 or 11.8 (unless no adjustment is to occur pursuant to
               Section 11.10); or

                    (2)  the Company takes any action that would require a
               supplemental indenture pursuant to Section 11.14; or

                    (3)  there is a liquidation or dissolution of the
               Company;

          then the Company shall mail to Securityholders and file with the
          Trustee and the Conversion Agent a notice stating the proposed
          record date for a dividend or distribution of the proposed
          effective date of a subdivision, combination, reclassification,
          consolidation, merger, binding share exchange, transfer,
          liquidation or dissolution.  The Company shall file and mail the
          notice at least 15 days before such date.  Failure to file or
          mail the notice or any defect in it shall not affect the validity
          of the transaction.

               SECTION 11.14.  REORGANIZATION OF COMPANY; SPECIAL
          DISTRIBUTIONS.  If the Company is a party to a transaction
          subject to Section 5.1 (other than a sale of all or substantially
          all of the assets of the Company in a transaction in which the
          holders of Common Stock immediately prior to such transaction do
          not receive securities, cash or other assets of the Company or
          any other person) or a merger or binding share exchange which
          reclassifies or changes its outstanding Common Stock, the person
          obligated to deliver securities, cash or other assets upon
          conversion of Securities shall enter into a supplemental
          indenture.  If the issuer of securities deliverable upon
          conversion of Securities is an Affiliate of the successor
          Company, that issuer shall join in the supplemental indenture.

               The supplemental indenture shall provide that the Holder of
          a Security may convert it into the kind and amount of securities,
          cash or other assets which such Holder would have received
          immediately after the consolidation, merger, binding share
          exchange or transfer if such Holder had converted the Security
          immediately before the effective date of the transaction,


                                      65

          assuming (to the extent applicable) that such Holder (i) was not
          a constituent person or an Affiliate of a constituent person to
          such transaction; (ii) made no election with respect thereto; and
          (iii) was treated alike with the plurality of non-electing
          Holders.  The supplemental indenture shall provide for
          adjustments which shall be as nearly equivalent as may be
          practical to the adjustments provided for in this Article 11.
          The successor Company shall mail to Securityholders a notice
          briefly describing the supplemental indenture.

               If this Section applies, neither Section 11.6 nor 11.7
          applies.

               If the Company makes a distribution to all holders of its
          Common Stock of any of its assets, or debt securities or any
          rights, warrants or options to purchase securities of the Company
          that, but for the provisions of the last paragraph of Section
          11.8, would otherwise result in an adjustment in the Conversion
          Rate pursuant to the provisions of Section 11.8, then, from and
          after the record date for determining the holders of Common Stock
          entitled to receive the distribution, a Holder of a Security that
          converts such Security in accordance with the provisions of this
          Indenture shall upon such conversion be entitled to receive, in
          addition to the shares of Common Stock into which the Security is
          convertible, the kind and amount of assets, debt securities or
          rights, warrants or options comprising the distribution that such
          Holder would have received if such Holder had converted the
          Security immediately prior to the record date for determining the
          holders of Common Stock entitled to receive the distribution.

               SECTION 11.15.  COMPANY DETERMINATION FINAL.  Any
          determination that the Company or the Board of Directors must
          make pursuant to Section 11.3, 11.6, 11.7, 11.8, 11.9, 11.10,
          11.14 or 11.17 is conclusive.

               SECTION 11.16.  TRUSTEE'S ADJUSTMENT DISCLAIMER.  The
          Trustee has no duty to determine when an adjustment under this
          Article 11 should be made, how it should be made or what it
          should be.  The Trustee has no duty to determine whether a
          supplemental indenture under Section 11.14 need be entered into
          or whether any provisions of any supplemental indenture are
          correct.  The Trustee shall not be accountable for and makes no
          representation as to the validity or value of any securities or
          assets issued upon conversion of Securities.  The Trustee shall
          not be responsible for the Company's failure to comply with this
          Article 11.  Each Conversion Agent (other than the Company or an
          Affiliate of the Company) shall have the same protection under
          this Section 11.16 as the Trustee.

               SECTION 11.17.  SIMULTANEOUS ADJUSTMENTS.  If this Article
          11 requires adjustments to the Conversion Rate under more than
          one of Sections 11.6, 11.7 or 11.8, and the record dates for the
          distributions giving rise to such adjustments shall occur on the
          same date, then such adjustments shall be made by applying,
          first, the provisions of Section 11.6, second, the provisions of
          Section 11.8 and, third, the provisions of Section 11.7.

               SECTION 11.18.  SUCCESSIVE ADJUSTMENTS.  After an adjustment
          to the Conversion Rate under this Article 11, any subsequent
          event requiring an adjustment under this Article 11 shall cause
          an adjustment to the Conversion Rate as so adjusted.

               Failure to mail a notice or communication to a
          Securityholder or any defect in it shall not affect its
          sufficiency with respect to other Securityholders.  If a notice
          or communication is mailed in the manner provided above, it is

                    (2)  an Opinion of Counsel stating that, in the opinion
               of such counsel, all such conditions precedent have been

                    (3)  a statement that, in the opinion of each such
               person, he has made such examination or investigation as is
               necessary to enable such person to express an informed

               been complied with; and

               SECTION 12.6.  SEPARABILITY CLAUSE.  In case any provision
          in this Indenture or in the Securities shall be invalid, illegal
          or unenforceable, the validity, legality and enforceability of

          AGENT AND REGISTRAR.  The Trustee may make reasonable rules for
          action by or a meeting of the Securityholders.  The Registrar,

               SECTION 12.8.  LEGAL HOLIDAYS.  A "Legal Holiday" is any day
          other than a Business Day.  If any specified date (including a
          date for giving notice) is a Legal Holiday, the action shall be
          taken on the next succeeding day that is not a Legal Holiday, and
          to the extent applicable no Original Issue Discount or interest,
          if any, shall accrue for the intervening period.

               SECTION 12.9.  GOVERNING LAW.  THIS INDENTURE AND THE
          SECURITIES SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH

          PRINCIPLES OF CONFLICT OF LAWS.

               SECTION 12.10.  NO RECOURSE AGAINST OTHERS.  A director,

          the Securities or this Indenture or for any claim based on, in
          respect of or by reason of such obligations or their creation.
          By accepting a Security, each Securityholder shall waive and
          release all such liability.  The waiver and release shall be part
          of the consideration for the issue of the Securities.

               SECTION 12.11.  SUCCESSORS.  All agreements of the Company
          in this Indenture and the Securities shall bind its successor.

          any number of copies of this Indenture.  Each signed copy shall
          be an original, but all of them together represent the same
          agreement.  One signed copy is enough to prove this Indenture.

          1.   INTEREST

               This Security shall not bear interest, except that if the
          Principal Amount hereof or any portion of such Principal Amount
          is not paid when due (whether upon acceleration pursuant to
          Section 6.2 of the Indenture, upon the date set for payment of
          the Redemption Price pursuant to paragraph 5 hereof, upon the
          date set for payment of a Purchase Price or Change in Control
          Purchase Price pursuant to paragraph 6 hereof or upon the Stated
          Maturity of this Security) or if cash or shares of Common Stock
          in respect of a conversion of this Security in accordance with
          the terms of Article 11 of the Indenture is not paid or
          delivered, as the case may be, when due, then in each such case
          the overdue amount shall bear interest at the rate of ___% per
          annum, compounded semiannually (to the extent that the payment of
          such interest shall be legally enforceable), which interest shall
          accrue from the date such overdue amount was due to the date
          payment of such amount, including interest thereon, has been made
          or duly provided for.  All such interest shall be payable on
          demand.

               Original Issue Discount (the difference between the Issue
          Price and the Principal Amount of the Security), in the period
          during which a Security remains outstanding, shall accrue at ___%
          per annum, on a semiannual bond equivalent basis using a 360-day
          year composed of twelve 30-day months, commencing on the Issue
          Date of this Security.

          2.   METHOD OF PAYMENT

               Subject to the terms and conditions of the Indenture, ALZA
          Corporation (the "Company") will make payments in respect of the
          Securities to the persons who are registered Holders of
          Securities at the close of business on the Business Day preceding
          the Redemption Date or Stated Maturity, as the case may be, or at
          the close of business on a Purchase Date or Change in Control
          Purchase Date, as the case may be.  Holders must surrender
          Securities to a Paying Agent to collect such payments in respect
          of the Securities.  The Company will pay cash amounts in money of
          The United States of America that at the time of payment is legal
          tender for payment of public and private debts.  However, the

          Company may make such cash payments by check payable in such
          money.

          3.   PAYING AGENT, CONVERSION AGENT AND REGISTRAR

          appoint and change any Paying Agent, Conversion Agent, Registrar
          or co-registrar (with the consent of the Trustee), upon notice to
          the Trustee and the Holders.  The Company or any of its
          Subsidiaries or any of their Affiliates may act as Paying Agent,
          Conversion Agent, Registrar or co-registrar.

          4.   INDENTURE

               The Company issued the Securities under an Indenture, dated
          as of June 1, 1994 (the "Indenture"), between the Company and the
          Trustee.  The terms of the Securities include those stated in the
          Indenture and those made part of the Indenture by reference to
          the Trust Indenture Act of 1939, as amended, as in effect on the
          date of the Indenture, except as provided in Section 9.3 of the
          Indenture (the "TIA").  Capitalized terms used herein or on the
          face hereof and not defined herein have the meanings ascribed
          thereto in the Indenture.  The Securities are subject to all such
          terms, and Securityholders are referred to the Indenture and the
          TIA for a statement of those terms.

               The Securities are general unsecured obligations of the
          Company limited to $___,000,000 aggregate Principal Amount
          (subject to Sections 2.2 and 2.7 of the Indenture) plus
          Securities not exceeding $___,___,000 aggregate Principal Amount
          sold pursuant to the Over-allotment Option.  The Indenture does
          not limit other indebtedness of the Company, secured or
          unsecured, including Senior Indebtedness.

          5.   REDEMPTION AT THE OPTION OF THE COMPANY

               No sinking fund is provided for the Securities.  The
          Securities are redeemable as a whole, or from time to time in
          part, at any time at the option of the Company at the Redemption
          Prices set forth below, PROVIDED, that the Securities are not
          redeemable prior to June __, 1999.

               The table below shows the Redemption Prices of a Security
          per $1,000 Principal Amount on the dates shown below and at
          Stated Maturity, which prices reflect accrued Original Issue
          Discount calculated to each such date.  The Redemption Price of a
          Security redeemed between such dates would include an additional
          amount reflecting the additional Original Issue Discount accrued

          6.   PURCHASE BY THE COMPANY AT THE OPTION OF THE HOLDER

               Subject to the terms and conditions of the Indenture, the
          Company shall become obligated to purchase, at the option of the
          Holder, the Securities held by such Holder on the following
          Purchase Dates and at the following Purchase Prices per $1,000
          Principal Amount, upon delivery of a Purchase Notice containing
          the information set forth in the Indenture, at any time from the
          opening of business on the date that is 20 Business Days prior to
          such Purchase Date until the close of business on such Purchase
          Date and upon delivery of the Securities to the Paying Agent by
          the Holder as set forth in the Indenture.  Such Purchase Price
          may be paid, at the option of the Company, in cash or by the
          issuance and delivery of shares of Common Stock of the Company,
          or in any combination thereof.

               Subject to the terms and conditions of the Indenture, if any
          Change in Control occurs on or prior to June __,  1999, the
          Company shall, at the option of the Holders, purchase all


                                      A-5

<PAGE>

          Securities for which a Change in Control Purchase Notice shall
          have been delivered as provided in the Indenture and not
          withdrawn, on the date that is 35 Business Days after the
          occurrence of such Change in Control, for a Change in Control
          Purchase Price equal to the Issue Price plus accrued Original
          Issue Discount to the Change in Control Purchase Date, which
          Change in Control Purchase Price shall be paid in cash.

               Holders have the right to withdraw any Purchase Notice or
          Change in Control Purchase Notice, as the case may be, by
          delivering to the Paying Agent a written notice of withdrawal in
          accordance with the provisions of the Indenture.

               If cash (or securities if expressly permitted under the
          Indenture) sufficient to pay the Purchase Price or Change in
          Control Purchase Price, as the case may be, of all Securities or
          portions thereof to be purchased as of the Purchase Date or the
          Change in Control Purchase Date, as the case may be, is deposited
          with the Paying Agent on the Business Day following the Purchase
          Date or the Change in Control Purchase Date, as the case may be,
          Original Issue Discount ceases to accrue on such Securities (or
          portions thereof) on and after such date, and the Holders thereof
          shall have no other rights as such (other than the right to
          receive the Purchase Price or Change in Control Purchase Price,
          as the case may be, upon surrender of such Security).

          7.   NOTICE OF REDEMPTION

               Notice of redemption will be mailed at least 30 days but not
          more than 60 days before the Redemption Date to each Holder of
          Securities to be redeemed at the Holder's registered address.  If
          money sufficient to pay the Redemption Price of all Securities
          (or portions thereof) to be redeemed on the Redemption Date is
          deposited with the Paying Agent prior to or on the Redemption
          Date, on and after such date Original Issue Discount ceases to
          accrue on such Securities or portions thereof.  Securities in
          denominations larger than $1,000 of Principal Amount may be
          redeemed in part but only in integral multiples of $1,000 of
          Principal Amount.

          8.   SUBORDINATION

               The Securities are subordinated to all existing and future
          Senior Indebtedness.  To the extent provided in the Indenture,
          Senior Indebtedness must be paid before the Securities may be
          paid.  The Indenture does not limit the present or future amount
          of Senior Indebtedness the Company may have.  The Company agrees,
          and each securityholder by accepting a Security agrees, to the
          subordination and authorizes the Trustee to give it effect and
          appoints the Trustee as attorney-in-fact for such purpose.

          9.   CONVERSION

               Subject to the second and third succeeding sentences, a
          Holder of a Security may convert it into Common Stock of the
          Company at any time before the close of business on June __,
          2014; PROVIDED, HOWEVER, that if a Security is called for
          redemption, the Holder may convert it at any time before the
          close of business on the Redemption Date.  The number of shares
          of Common Stock to be delivered upon conversion of a Security
          into Common Stock per $1,000 of Principal Amount shall be equal
          to the Conversion Rate.  A Holders' right to convert Securities
          into Common Stock is subject to the Company's right to elect to
          pay such Holder surrendering a Security pursuant to Article 11 of
          the Indenture an amount of cash as set forth in the next
          succeeding sentence, in lieu of delivering such shares of Common
          Stock.  The amount of cash to be paid per $1,000 of Principal
          Amount of a Security upon conversion of such Security shall be
          equal to the Sale Price of a share of Common Stock on the Trading
          Day immediately prior to the related Conversion Date multiplied
          by the Conversion Rate in effect on such Trading Day.  A Security
          in respect of which a Holder has delivered a Purchase Notice or
          Change in Control Purchase Notice exercising the option of such
          Holder to require the Company to purchase such Security may be
          converted only if the notice of exercise is withdrawn in
          accordance with the terms of the Indenture.

               The initial Conversion Rate is _____ shares of Common Stock
          per $1,000 Principal Amount, subject to adjustment in certain
          events described in the Indenture.  The Company will deliver cash
          or a check in lieu of any fractional share of Common Stock.

               To convert a Security a Holder must (i) complete and
          manually sign the conversion notice on the back of the Security
          (or complete and manually sign a facsimile of such notice) and
          deliver such notice to the Conversion Agent (or the office or
          agency referred to in Section 4.5 of the Indenture) or, if
          applicable, complete and deliver to The Depository Trust Company
          ("DTC", which term includes any successor thereto) the
          appropriate instruction form for conversion pursuant to DTC's
          book entry conversion program, (ii) surrender the Security to a
          Conversion Agent by physical or book entry delivery (which is not
          necessary in the case of conversion pursuant to DTC's book entry
          conversion program), (iii) furnish appropriate endorsements and
          transfer documents if required by the Conversion Agent, the
          Company or the Trustee and (iv) pay any transfer or similar tax,
          if required.  Book entry delivery of a Security to a Conversion
          Agent may be made by any financial institution that is a
          participant in DTC; conversion through DTC's book entry
          conversion program is available for any security that is held in
          an account maintained at DTC by any such participant.


                                      A-7

<PAGE>

               A Holder may convert a portion of a Security if the
          Principal Amount of such portion is $1,000 or an integral
          multiple of $1,000.  No payment or adjustment will be made for
          dividends on the Common Stock except as provided in the
          Indenture.  On conversion of a Security, that portion of accrued
          Original Issue Discount attributable to the period from the Issue
          Date to the Conversion Date with respect to the converted
          Security shall not be cancelled, extinguished or forfeited, but
          rather shall be deemed paid in full to the Holder thereof through
          the delivery of the Common Stock in exchange for the Security
          being converted pursuant to the terms hereof.

               The Conversion Rate will be adjusted for dividends or
          distributions on Common Stock payable in Common Stock or other
          Capital Stock; subdivisions, combinations or certain
          reclassifications of Common Stock; distributions to all holders
          of Common Stock of certain rights to purchase Common Stock for a
          period expiring within 60 days at less than the Sale Price at the
          Time of Determination; and distributions to such holders of
          assets or debt securities of the Company or certain rights to
          purchase securities of the Company (excluding certain cash
          dividends or distributions).  However, no adjustment need be made
          if Securityholders may participate in the transaction or in
          certain other cases.  The Company from time to time may
          voluntarily increase the Conversion Rate.

               If the Company is a party to a consolidation, merger or
          binding share exchange of the type specified in the Indenture, or
          certain transfers of all or substantially all of its assets to
          another person, or in certain other circumstances described in
          the Indenture, the right to convert a Security into Common Stock
          may be changed into a right to convert it into securities, cash
          or other assets of the Company or another person.

          10.  CONVERSION ARRANGEMENT ON CALL FOR REDEMPTION

               Any Securities called for redemption, unless surrendered for
          conversion before the close of business on the Redemption Date,
          may be deemed to be purchased from the Holders of such Securities
          at an amount not less than the Redemption Price, by one or more
          investment bankers or other purchasers who may agree with the
          Company to purchase such Securities from the Holders and to make
          payment for such Securities to the Trustee in trust for such
          Holders.

          11.  DENOMINATIONS; TRANSFER; EXCHANGE

               The Securities are in registered form, without coupons, in
          denominations of $1,000 of Principal Amount and integral
          multiples of $1,000.  A Holder may transfer or exchange
          Securities in accordance with the Indenture.  The Registrar may


                                      A-8

<PAGE>

          require a Holder, among other things, to furnish appropriate
          endorsements and transfer documents and to pay any taxes and fees
          required by law or permitted by the Indenture.  The Registrar
          need not transfer or exchange any Securities selected for
          redemption (except, in the case of a Security to be redeemed in
          part, the portion of the Security not to be redeemed) or any
          Securities in respect of which a Purchase Notice or Change in
          Control Purchase Notice has been given and not withdrawn (except,
          in the case of a Security to be purchased in part, the portion of
          the Security not to be purchased) or any Securities for a period
          of 15 days before a selection of Securities to be redeemed.

          12.  PERSONS DEEMED OWNERS

               The registered Holder of this Security may be treated as the
          owner of this Security for all purposes.

          13.  UNCLAIMED MONEY OR SECURITIES

               The Trustee and the Paying Agent shall return to the Company
          upon written request any money or securities held by them for the
          payment of any amount with respect to the Securities that remains
          unclaimed for two years, PROVIDED, HOWEVER, that the Trustee or
          such Paying Agent, before being required to make any such return,
          may at the expense of the Company cause to be published once in
          THE WALL STREET JOURNAL or another newspaper of national
          circulation or mail to each such Holder notice that such money or
          securities remains unclaimed and that, after a date specified
          therein, which shall not be less than 30 days from the date of
          such publication or mailing, any unclaimed money or securities
          then remaining will be returned to the Company.  After return to
          the Company, Holders entitled to the money or securities must
          look to the Company for payment as general creditors unless an
          applicable abandoned property law designates another person.

          14.  AMENDMENT; WAIVER

               Subject to certain exceptions set forth in the Indenture,
          (i) the Indenture or the Securities may be amended with the
          written consent of the Holders of at least a majority in
          aggregate Principal Amount of the Securities at the time
          outstanding and (ii) certain defaults or noncompliance with
          certain provisions may be waived with the written consent of the
          Holders of a majority in aggregate Principal Amount of the
          Securities at the time outstanding.  Subject to certain
          exceptions set forth in the Indenture, without the consent of any
          Securityholder, the Company and the Trustee may amend the
          Indenture or the Securities to, among other things, cure any
          ambiguity, defect or inconsistency, or to comply with Article 5
          or Section 11.14 of the Indenture or to make any change that does
          not adversely affect the rights of any Securityholder.

          15.  DEFAULTS AND REMEDIES

               Under the Indenture, Events of Default include (i) default
          in payment of the Principal Amount, Issue Price, accrued Original
          Issue Discount, Redemption Price, Purchase Price or Change in
          Control Purchase Price, as the case may be, in respect of the
          Securities when the same becomes due and payable; (ii) failure by
          the Company to deliver shares of Common Stock or pay cash in lieu
          thereof when such Common Stock or cash is required to be
          delivered or paid, as the case may be, following conversion of a
          Security; (iii) failure by the Company to comply with other
          agreements in the Indenture or the Securities, subject to notice
          and lapse of time; (iv) default under any mortgage, indenture or
          instrument under which there maybe issued or by which there may
          be secured or evidenced any indebtedness for money borrowed of
          the Company, which default shall have resulted in such
          indebtedness, in an aggregate principal amount exceeding
          $25,000,000, becoming or being declared due and payable prior to
          the date on which it would otherwise have become due and payable
          without such indebtedness being discharged or such acceleration
          having been rescinded or annulled, or there having been deposited
          in trust a sum of money sufficient to discharge such indebtedness
          within a period of 30 days after the giving of a Notice of
          Default; or (v) certain events of bankruptcy or insolvency.  If
          an Event of Default occurs and is continuing, the Trustee, or the
          Holders of at least 25% in aggregate Principal Amount of the
          Securities at the time outstanding, may declare all the
          Securities to be due and payable immediately.  Certain events of
          bankruptcy or insolvency are Events of Default which will result
          in the Securities becoming due and payable immediately upon the
          occurrence of such Events of Default.

               Securityholders may not enforce the Indenture or the
          Securities except as provided in the Indenture.  The Trustee may
          refuse to enforce the Indenture or the Securities unless it
          receives reasonable indemnity or security.  Subject to certain
          limitations, Holders of a majority in aggregate Principal Amount
          of the Securities at the time outstanding may direct the Trustee
          in its exercise of any trust or power.  The Trustee may withhold
          from Securityholders notice of any continuing Default (except a
          Default in payment of amounts specified in clause (i) above) if
          it determines that withholding notice is in their interests.

               Subject to certain limitations imposed by the TIA, the
          Trustee under the Indenture, in its individual or any other
          capacity, may become the owner or pledgee of Securities and may
          otherwise deal with and collect obligations owed to it by the
          Company or its Affiliates and may otherwise deal with the Company


                                      A-10

          or its Affiliates with the same rights it would have if it were
          not Trustee.

          17.  NO RECOURSE AGAINST OTHERS

               A director, officer, employee or stockholder, as such, of
          the Company shall not have any liability for any obligations of
          the Company under the Securities or the Indenture or for any
          claim based on, in respect of or by reason of such obligations or
          their creation.  By accepting a Security, each Securityholder
          waives and releases all such liability.  The waiver and release
          are part of the consideration for the issue of the Securities.

          18.  AUTHENTICATION

               This Security shall not be valid until an authorized
          signatory of the Trustee manually signs the Certificate of
          Authentication on the other side of this Security.

          19.  ABBREVIATIONS

          and CUST (=custodian), and UNIF TRANS MIN ACT (=Uniform Transfers
          to Minors Act).

          20.  GOVERNING LAW

                       REGISTRATION STATEMENT ON FORM S-3

Ladies and Gentlemen:

          We have acted as counsel to ALZA Corporation, a Delaware corporation
(the "Company"), in connection with the Registration Statement on Form S-3 to be
filed with the Securities and Exchange Commission on or about May 17, 1994 (the
"Registration Statement"), relating to $ 948,750,000 principal amount at
maturity of Liquid Yield Option -TM- Notes due 2014 (the "LYONs"), including
the shares of Common Stock issuable upon conversion thereof (the "Shares") at
the initial Conversion Rate defined in the form of Indenture included as
Exhibit 4.2 to the Registration Statement (the "Indenture"), all as disclosed
in the Registration Statement.

                                       I.

          We have assumed the authenticity of all records, documents and
instruments submitted to us as originals, the genuineness of all signatures, the
legal capacity of all natural persons and the conformity to the originals of all
records, documents and instruments submitted to us as copies.  We have based our
opinion upon the following records, documents, instruments and certificates and
such additional certificates relating to factual matters as we have deemed
necessary or appropriate for our opinion:

               (a)  The Certificate of Incorporation of the Company, certified
                    by the Secretary of State of the State of Delaware as of
                    May 9, 1994 and certified to us by an officer of the
                    Company as being complete and in full force and effect as
                    of the date of this opinion;

               (b)  The Bylaws of the Company certified to us by an officer of
                    the Company as being complete and in full force and effect
                    as of the date of this opinion;

               (c)  Certifications by officers of the Company (i) as to all of
                    the proceedings and actions of the Board of Directors of the
                    Company relating to the LYONs and the Shares, and (ii) as to
                    certain other factual matters;

               (d)  The Registration Statement;

               (e)  The Indenture; and

               (f)  Certification by an officer of The First National Bank of
                    Boston, transfer agent for the Company's Common Stock, as to
                    certain factual matters.

          We have assumed that the number of Shares issuable upon exercise of
the LYONs at the Conversion Rate is less than 210,526,402, the number of shares
of Common Stock of the Company currently authorized but not outstanding or
otherwise reserved for issuance and that this number of shares of Common Stock
will be available for issuance at the time of conversion.

          This opinion is limited to the General Corporation Law of the State of
Delaware, and we disclaim any opinion as to the laws of any other jurisdiction.
We further disclaim any opinion as to any statute, rule, regulation, ordinance,
order or other promulgation of any regional or local governmental body or as to
any related judicial or administrative opinion.

          Based upon the foregoing and our examination of such questions of law
as we have deemed necessary or appropriate for the purpose of this opinion, and
assuming (i) that the full consideration for each LYON and each Share as stated
in the Indenture and the Registration Statement is paid, and (ii) that all
applicable securities laws are complied with, it is our opinion that, when
issued and sold by the Company, the LYONs and the Shares will be legally issued,
fully paid and nonassessable.

          This opinion is rendered to you in connection with the Registration
Statement and is solely for your benefit.  This opinion may not be relied upon
by any other person, firm, corporation or other entity without our prior written
consent.  We disclaim any obligation to advise you of any change of law

opinion.

     Re:  REGISTRATION STATEMENT ON FORM S-3

Ladies and Gentlemen:

     We are acting as your special United States federal income tax counsel in
connection with the registration under the Securities Act of 1933, as amended,
of $948,750,000 aggregate principal amount at maturity of Liquid Yield Option -
TM- Notes due 2014 (Zero Coupon-Subordinated) (the "LYONs"-TM-) of ALZA
Corporation (the "Company"). In that capacity, we have examined the Registration
Statement on Form S-3 (the "Registration Statement") filed by the Company with
the Securities and Exchange Commission in connection with the proposed public
offering of the LYONs.

     We hereby confirm our opinion set forth in the Prospectus in the second
full paragraph under the caption "Certain United States Federal Income Tax
Considerations." Furthermore, we are of the opinion that the information in the
Registration Statement under the caption "Certain United States Federal Income
Tax Considerations," while not purporting to discuss all tax matters relating to
the LYONs, to the extent that it constitutes a summary of United States federal
income tax matters relating to the LYONs, is correct in all material respects.

     The foregoing is based on the Internal Revenue Code of 1986, as amended
(the "Code"), Treasury Regulations (including proposed Treasury Regulations)
promulgated thereunder, rulings, official pronouncements and judicial decisions,
all as in effect on the date hereof and all of which are subject to change or
different interpretations by the Internal Revenue Service or the courts.

     We consent to the use of this opinion as an exhibit to the Registration
Statement and further consent to the reference to our firm as special United
States federal income tax counsel to the Company under the caption "Legal
Matters" in the Registration statement and the Prospectus which forms a part
thereof.

                                             Very truly yours,
