Item 3.  Past Contacts, Transactions or Negotiations.
- ---------------------------------------------------- 

     (a)  (1)  The nature and approximate amount in dollars of any transaction
          which has occurred since the commencement of the Issuer's second full
          fiscal year preceding the date of this Statement between ALZA and ADC
          on one hand and the Issuer on the other hand are as follows:

               As part of its initial organization and funding, the Issuer
          granted ALZA an option (the "License Option") to acquire a license
          for any or all of the products (the "Issuer Products") for which
          development was funded by the Issuer under its Research and
          Development Agreement with ALZA. In 1990, ALZA exercised its License
          Option for two Issuer Products: (i) a transdermal fentanyl product
          sold in the United States under the name Duragesic(R) and (ii) a
          transdermal testosterone product sold under the name Testoderm(R).
          Under each license, ALZA makes payments to the Issuer based on
          ALZA's and its affiliates' and sublicensees' sales of the licensed
          product. ALZA paid the Issuer $2,644,646, $8,776,814 and $6,265,401
          for the three months ended March 31, 1998 and the years ended
          December 31, 1997 and December 31, 1996, respectively, of which
          approximately 97.5%, 95% and 96% were attributed to Duragesic(R) for
          the three months ended March 31, 1998 and fiscal 1997 and 1996,
          respectively.

               The administrative, accounting, contract management and record
          keeping services required by the Issuer have been provided in the past
          and are currently being provided by ALZA and are billed to the Issuer
          at ALZA's standard administrative services rate. The Issuer paid ALZA
          $18,835, $105,512 and $86,548 for the three months ended March 31,
          1998 and the years ended December 31, 1997 and December 31, 1996,
          respectively.

          (2)  On November 20, 1997, PharmaInvest, L.L.C. ("PharmaInvest") on
          behalf of Pharmaceutical Royalties L.L.C., Pharmaceutical Royalty
          Investments Ltd. and Pharmaceutical Partners L.L.C. ("Pharmaceutical
          Partners") made an unsolicited tender offer (the "Tender Offer") to
          purchase up to 1,400 Class A Limited Partnership Interests,
          representing approximately 44% of the total outstanding Class A
          Limited Partnership Interests, for cash consideration per Class A
          Limited Partnership Interest of $12,000.  In response to the Tender
          Offer, the General Partner filed a Schedule 14D-9 (the "Schedule 14D-
          9") with the Securities and Exchange Commission (the "Commission"), in
          which the General Partner expressed no opinion with respect to the
          Tender Offer to the holders of the Class A Limited Partnership
          Interests and stated that the General Partner would remain neutral as
          to whether the Limited Partners should tender or refrain from
          tendering their Class A Limited Partnership Interests.  In its letter
          to 

                                       8
<PAGE>
 
          the Limited Partners advising them of its neutrality with respect to
          the Tender Offer, the General Partner drew the attention of the
          Limited Partners to certain facts, including, (i) the dates on which
          ALZA's exclusive rights with respect to Duragesic(R) and Testoderm(R)
          were scheduled to expire, (ii) the General Partner's expectation of
          the growth of sales of Duragesic(R) and (iii) the report of Securities
          Pricing and Research, Inc., an independent appraisal firm ("SPAR"),
          estimating that the rounded net asset value and fair market value of a
          Class A Limited Partnership Interest as of December 31, 1996 were
          $21,200 and $15,900, respectively. None of ADC, ALZA or the Issuer has
          any affiliation with SPAR, nor does any of them endorse the report
          prepared by SPAR (the "SPAR Report"). In addition, neither the General
          Partner nor the Issuer engaged SPAR to prepare the SPAR Report or
          participated in the preparation of the SPAR Report. The SPAR Report
          was not related to the Tender Offer and is not related to the Purchase
          Option.

               Also on November 20, 1997, Pharmaceutical Partners, an
          affiliate of PharmaInvest,  in a letter addressed to ALZA, set forth
          its views about the Purchase Option and its effects on the Limited
          Partners, the Issuer, the General Partner and ALZA.  In connection
          with the Issuer's consideration and evaluation of the Tender Offer,
          ALZA, on December 2, 1997, advised the Issuer of the matters raised in
          Pharmaceutical Partners' letter to ALZA and informed the Issuer of
          ALZA's position regarding such matters.  A copy of such letter was,
          with ALZA's permission, included as an exhibit to the Schedule 14D-9
          and sent to the holders of the Limited Partnership Interests.  On
          January 16, 1998, PharmaInvest amended its offer by increasing the
          purchase price of each Class A Limited Partnership Interest from
          $12,000 to $13,200.  In connection with the increase in the purchase
          price, the General Partner filed an amendment to its Schedule 14D-9
          stating that the General Partner continued to express no opinion to
          the holders of the Class A Limited Partnership Interests and that the
          General Partner would continue to remain neutral as to whether the
          Limited Partners should tender or refrain from tendering their Class A
          Limited Partnership Interests. In addition, the General Partner
          informed the Limited Partners that in reaching its conclusion with
          respect to the Tender Offer, the General Partner had taken into
          account (i) that SPAR had reduced its estimates of the rounded net
          asset value and fair market value of the Class A Limited Partnership
          Interests as of December 31, 1996, and (ii) the General Partner's
          expectation of the growth of sales of Duragesic.  On February 2, 1998,
          PharmaInvest announced that the Tender Offer had expired and that 72
          Class A Limited Partnership Interests were tendered in connection with
          the Tender Offer.

     (b)  As described in Section (a)(2) above, in November 1997, PharmaInvest
          made the Tender Offer. In the last fiscal year, PharmaInvest contacted
          the General Partner to make it aware of its possible interest in the
          Issuer as an investment opportunity. PharmaInvest sent letters on July
          11 and 17, 1997 continuing to express its interest in the Issuer. In
          October 1997, PharmaInvest had a conversation with the General Partner
          reiterating its interest in the Issuer. Following the conversation,
          PharmaInvest acquired two Class A Limited Partnership Interests, and
          on October 22, 1997 made a written request to receive a list of names
          and addresses of Limited Partners (the "List"). PharmaInvest received
          the List on November 2, 1997 and commenced the Tender Offer on
          November 20, 1997.

Item 4.  Terms of Transaction.
- ----------------------------- 

     (a)  Pursuant to the terms of the Limited Partnership Agreement, ADC has an
          option to purchase all (but not less than all) of the Limited
          Partnership Interests (the "Purchase Option"). The exercise price for
          exercise of the Purchase Option is $120 million less an amount equal
          to all cash distributed to the Limited Partners by the Issuer (the
          "Exercise Price").  As of the date hereof, the Exercise Price is
          $91,176,592.48.  The Exercise Price will be allocated among the
          Limited Partners based on their pro rata contributions.  At the
                                          ---------                      
          closing (the "Closing"), the holders of record of Class A Limited
          Partnership Interests as of the Closing date will receive $27,216.21
          per Class A Limited Partnership Interest (purchased in the original
          offering for $5,000 each) and the holder of the Class B Limited
          Partnership Interest will receive $4,084,720.48 for its Class B
          Limited Partnership Interest.  The Exercise Price will be paid by
          check to each holder of the Limited Partnership Interests.


          In accordance with the terms of the Limited Partnership Agreement, the
          Limited Partners are not required to take any steps to approve the
          exercise of the Purchase Option or the consummation of the
          transactions pursuant to the Purchase Option. Title to the Limited
          Partnership Interests automatically vests in ADC no later than 30 days
          after notice of the exercise of the Purchase Option is given to the
          Limited Partners, upon payment of the Purchase Price for the Limited
          Partnership Interests.  The exact date of Closing will be set forth in
          the Notice to Limited Partners of the Issuer to be distributed to the
          Limited Partners. 

     (b)  Not applicable.

<PAGE>
 
Item 5.  Plans or Proposals of the Issuer or Affiliate.
- ------------------------------------------------------ 

     Exercise of the Purchase Option will result in ADC owning all of the
Limited Partnership Interests. Upon purchase of all of the Limited Partnership
Interests by ADC, the Issuer will terminate as a limited partnership and the
General Partner will take all appropriate and necessary actions to suspend the
Issuer's public reporting obligations by filing a Form 15 with the Commission
and to wind up the affairs of the Issuer in accordance with California law. ADC
will continue as a wholly owned subsidiary of ALZA. Although ALZA and ADC have
no specific intentions with respect to the operations of the business of the
Issuer following the exercise of the Purchase Option, ALZA and ADC intend to
operate the business of the Issuer in a manner best designed, in the judgment of
ALZA, to realize the benefit of that business to ALZA and its stockholders.

Item 6.  Source and Amount of Funds or Other Consideration.
- ---------------------------------------------------------- 

     (a)  In accordance with the terms of the Limited Partnership Agreement, the
          Exercise Price is $91,176,592.48.  ALZA intends to contribute to ADC
          the amount of cash necessary to exercise the Purchase Option, which
          contribution ALZA intends to finance with its cash and marketable
          securities.

     (b)  The following tables set forth an estimate (except for the filing fee)
          of expenses for the transaction:

          Filing fees............................................    $ 18,236
          Accounting fees and expenses...........................       5,000
          Legal fees and expenses................................      25,000
          Printing expenses......................................       3,500
              Total..............................................    $ 51,736

          All of the expenses and fees will be paid by ALZA.

     (c)  Not applicable.

     (d)  Not applicable.

Item 7.  Purposes, Alternatives, Reasons and Effects.
- ---------------------------------------------------- 

     (a)  The purpose of this transaction is for ALZA, through ADC, to acquire
          all rights, on an exclusive basis, to the Issuer Products. ALZA
          believes that it is in the best interests of ALZA and ALZA's
          stockholders to exercise the Purchase Option at this time. ALZA has
          worldwide licenses, including the

                                       11
<PAGE>
 
          right to sublicense, to make, use and sell Testoderm(R) and
          Duragesic(R) products. Such licenses are currently exclusive; however,
          ALZA's exclusive rights with respect to Testoderm(R) and Duragesic(R)
          would end on July 26, 1998 and December 4, 1998, respectively. Because
          ALZA's exclusive rights are limited in duration, ALZA believes that
          exercising the Purchase Option is the most effective and comprehensive
          method of acquiring continued exclusive rights to Testoderm(R),
          Duragesic(R) and other Issuer Products. In addition, because ALZA's
          obligations to pay royalties to the Issuer under the licenses for
          Testoderm(R) and Duragesic(R) will terminate upon exercise of the
          Purchase Option, ALZA will benefit by retaining the full royalty 
          received on sales of Duragesic(R) and the full sales margin on 
          Testoderm(R).

     (b)  ADC and ALZA did not consider alternative means to accomplish the
          transaction because of the previously granted Purchase Option.

     (c)  The structure of the transaction is in accordance with the terms of
          the previously granted Purchase Option as set forth in the Limited
          Partnership Agreement. The transaction is being undertaken at this
          time because of the timing of the expiration of ALZA's exclusive
          rights discussed in Item 7(a) above.

     (d)  As a result of the transaction described herein, the Issuer will
          terminate as a limited partnership and the General Partner will take
          all appropriate and necessary actions to suspend the Issuer's public
          reporting obligations and to wind up the affairs of the Issuer in
          accordance with California law. The General Partner will continue as a
          wholly owned subsidiary of ALZA. For federal income tax purposes the
          Issuer will be treated as terminating on the date of the transaction
          and as distributing all of its assets, subject to all of its
          liabilities, to the General Partner on that date. The Issuer will not
          have taxable gain or loss as a result of the transaction described
          herein.

          The transaction described herein will cause each Limited Partner to
          dispose of its Limited Partnership Interests for consideration equal
          to such holder's pro rata share of the Exercise Price.  The following
                           --------                                            
          discussion sets forth general federal income tax considerations under
          the Internal Revenue Code (the "Code") for the Limited Partners with
          respect to cash received by the Limited Partners for the Limited
          Partnership Interests.  This discussion is intended only to provide
          general information to the Limited Partners that are subject to United
          States federal income tax; it may not address all relevant federal
          income tax consequences to such persons or to other categories of the
          Limited Partners (e.g., foreign persons, dealers in 
                            ----                                             

                                       12
<PAGE>
 
          securities, and persons that are exempt from federal income tax). This
          discussion is based upon present federal income tax laws and does not
          attempt to anticipate changes, including changes in tax rates, that
          may be made under currently pending legislative proposals. This
          discussion assumes that the Limited Partnership Interests were at all
          relevant times capital assets of the Limited Partners. This discussion
          does not address state, local or foreign tax considerations. ALL
          LIMITED PARTNERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS.

          Except as described below, the holder of a Limited Partnership
          Interest should generally have a capital gain or loss due to ADC's
          exercise of the Purchase Option equal to the difference between (i)
          the amount of cash received and (ii) the holder's basis in the Limited
          Partnership Interest.  A Limited Partner's basis in a Limited
          Partnership Interest is the Limited Partner's initial purchase price
          decreased by any partnership deductions taken by the Limited Partner
          and any cash distributed by the Issuer to the Limited Partner and
          increased by the Limited Partner's share of the Issuer's income. Under
          current law, capital gain or loss will be: (a) long-term if the
          Limited Partnership Interest has been held at least 18 months at the
          time the Purchase Option is exercised, (b) mid-term if the holding
          period is more than one year but less than (or equal to) 18 months,
          and (c) short term if the holding period is a year or less. Under
          Section 751 of the Code, the difference between the portion of the
          cash received by the holder that is attributable to "unrealized
          receivables" and "inventory" of the Issuer (together, "Section 751
          Property") over the portion of the holder's adjusted tax basis in the
          Limited Partnership Interest allocable to Section 751 Property will be
          treated as ordinary income or loss, rather than capital gain or loss.
          Although this conclusion is not entirely free from doubt, ADC believes
          that the only "unrealized receivables" of the Issuer should be the
          amount, if any, of accrued, but unpaid royalties under ALZA's licenses
          to Duragesic(R) and Testoderm(R). Treasury regulations require each
          person who transfers an interest in a partnership possessing Section
          751 Property to file a statement with such person's tax return
          reporting the transfer and certain other information relating thereto.
          Limitations may apply to deduction of capital loss.

          To the extent that any holder of a Limited Partnership Interest has
          not provided an appropriate taxpayer identification number on IRS Form
          W-9 or a substitute therefor, the holder may be subject to backup
          withholding by ALZA or ADC.

                                       13
<PAGE>
 
     (e)  The Purchase Price will be amortized by ALZA over a number of
          years.

Item 8.  Fairness of the Transaction.
- ------------------------------------ 

     (a)  Each of ADC and ALZA reasonably believes that the transaction reported
          herein is fair to the Limited Partners.  None of ALZA's or the General
          Partner's directors dissented to or abstained from voting on such
          transaction.

     (b)  Each of ADC and ALZA has based its respective belief that the
          transaction is fair to the holders of the Limited Partnership
          Interests on the fact that the Limited Partners were fully aware of
          the Purchase Option, which was an essential economic term of the
          Limited Partnership Interests, when they purchased their Limited
          Partnership Interests. The prospectus, pursuant to which the Limited
          Partnership Interests were offered and sold, fully described the
          Purchase Option. The Purchase Option, which is contained in the
          Limited Partnership Agreement, was also publicly filed with the
          Commission. The Limited Partners were also advised of the Purchase
          Option in each Form 10-K and each recent Form 10-Q public filing made
          by the Issuer with the Commission. In addition, the Limited Partners
          were reminded of the Purchase Option in connection with the Tender
          Offer and in evaluating whether or not to tender their Limited
          Partnership Interests in the Tender Offer. Accordingly, the Purchase
          Option was present in the initial public sale, was disseminated in the
          Issuer's charter documents and was discussed in the Issuer's periodic
          filings. As a result, every Limited Partner received substantial
          notice as to the terms of the Purchase Option prior to making any
          investment decision with respect to the Limited Partnership Interests.
          In addition, in its most recent filings the Issuer has indicated that
          ALZA's exclusive rights with respect to Duragesic(R) and Testoderm(R)
          would expire soon and that such expiration could lead to the exercise
          of the Purchase Option. In connection with its decision whether to
          exercise the Purchase Option, ALZA commissioned Frost & Sullivan, an
          independent market research firm ("Frost & Sullivan"), to prepare a
          market research report (the "Report") of revenue forecasts for
          Duragesic(R) (see Item 9 below). ALZA took into account the
          information contained in the Report in deciding whether the exercise
          of the Purchase Option was in the best interests of ALZA and ALZA's
          stockholders; however, because the Report did not assess the fairness
          of the exercise price of the Purchase Option, neither ALZA nor ADC
          considers that the Report is relevant with respect to the fairness of
          the transaction to the Limited Partners.

                                       14
<PAGE>
 
     (c)  The exercise of the Purchase Option and the consummation of the
          transactions thereunder do not require approval of the Limited
          Partners.

     (d)  No director of ALZA or the General Partner has retained an
          unaffiliated representative to act solely on behalf of the Limited
          Partners. As a limited partnership, the Issuer does not have any
          directors. Each director of the General Partner is an officer of the
          General Partner and an employee and officer or vice-president of ALZA.

     (e)  See Item 8(d) above.

     (f)  On November 20, 1997, PharmaInvest made the Tender Offer.  For further
          information with respect to the Tender Offer see Item 3(a)(2) above.

Item 9.  Reports, Opinions, Appraisals and Certain Negotiations.
- --------------------------------------------------------------- 

     (a)  In February of 1998, ALZA engaged Frost & Sullivan to prepare the 
          Report.

     (b)  ALZA engaged Frost & Sullivan to prepare the Report because of Frost &
          Sullivan's expertise with respect to analyzing sales and marketing
          information and trends of product sales in the pharmaceutical
          industry. Prior to engaging Frost & Sullivan, ALZA contacted several
          other market research firms, but chose Frost & Sullivan because of its
          availability and experience. ALZA has engaged Frost & Sullivan for
          other market research engagements from time to time and has paid
          normal service fees in connection with such engagements. The
          objectives of the Report were to (i) assess the revenue potential for
          Duragesic(R) during the period from 1997 to 2006, (ii) analyze the
          market opportunity for the same period, (iii) identify key competitive
          factors in the current and future market environment and (iv) identify
          key drivers of and restraints to market growth. After research using
          both primary and secondary sources, the key findings provided by the
          Report were (a) if a second transdermal product does not emerge on the
          market, Duragesic(R) is expected to continue to experience substantial
          growth throughout the forecast period due to an increased penetration
          into an expanding market, increased pricing and increased acceptance
          in key foreign markets, and (b) if a second transdermal product
          emerges on the market, in order to be competitive, a competitor would
          need to undercut the price of Duragesic(R).

     (c)  A copy of the Report is available for inspection and copying at the
          principal executive offices of ALZA during its regular business hours
          by any interested Limited Partner or his or her representative who has
          been so designated in writing.  A copy of the Report will be
          transmitted by ALZA 

                                       15
<PAGE>
 
          to any interested Limited Partner or his or her
          representative who has been so designated in writing upon written
          request and at the expense of the requesting Limited Partner.  A copy
          of the Report is also attached hereto as Exhibit (b).

Item 10.  Interest in Securities of the Issuer.
- ---------------------------------------------- 

     (a)  None of ADC, ALZA or any of their respective directors or officers own
          any Limited Partnership Interests. ALZA is the sole shareholder of the
          General Partner and each officer and director of the General Partner
          is an employee and officer or vice-president of ALZA. As described in
          this Statement, the General Partner may at any time, pursuant to the
          Purchase Option, purchase all of the outstanding Limited Partnership
          Interests.

     (b)  None.

Item 11. Contracts, Arrangements or Understandings With Respect to the Issuer's
- -------------------------------------------------------------------------------
         Securities.
         ---------- 

     Article Seven of the Limited Partnership Agreement grants ADC the Purchase
Option. The Purchase Option states that ADC may purchase all (but not less than
all) of the issued and outstanding Limited Partnership Interests at any time
after January 1, 1987 and prior to dissolution of the Issuer.  ADC may exercise
the Purchase Option by mailing a notice of exercise to the Limited Partners.

Item 12.  Present Intention and Recommendation of Certain Persons With Regard 
- -----------------------------------------------------------------------------
          to the Transaction.
          ------------------ 

     (a)  Not applicable.

     (b)  Not applicable.

Item 13.  Other Provisions of the Transaction.
- --------------------------------------------- 

     (a)  Appraisal rights are not afforded under applicable law in respect of
          the exercise of the Purchase Option and none will be afforded. Neither
          ALZA nor the General Partner is aware of any rights available to
          objecting holders of the Limited Partnership Interests under
          applicable law.

                                       16
<PAGE>
 
     (b)  None of ALZA, the General Partner or Issuer is aware of any grant of
          access to unaffiliated security holders to the corporate files of the
          Issuer or the appointment of counsel or appraisal services for
          unaffiliated security holders at the expense of the Issuer.

     (c)  Not applicable.

Item 14.  Financial Information.
- ------------------------------- 

     (a)  The Issuer's financial data is attached to this Statement as Exhibits
          (g)(1), (g)(2) and (g)(3).  The Issuer has no material fixed charges
          for the two most recent fiscal years and the appropriate interim
          period.  Book value per Class A Limited Partnership Interest at
          December 31, 1997 was $25.58 and at March 31, 1998 was $23.13.  Book
          value per Class B Limited Partnership Interest at December 31, 1997
          was $8,864 and at March 31, 1998 was $8,500.  Book value per General
          Partner interest at December 31, 1997 was $900 and at March 31, 1998
          was $849.

     (b)  The Issuer does not believe the pro forma disclosure required by this
          Item 14(b) is applicable because the Issuer would terminate upon
          giving effect to the transaction contemplated by this Schedule 13E-3.

Item 15.  Persons and Assets Employed, Retained or Utilized.

     (a)  Not applicable.

EXECUTIVE SUMMARY
- --------------------------------------------------------------------------------

SCOPE OF THE STUDY

                    Frost & Sullivan was commissioned by ALZA Corporation to
               provide revenue forecasts for Duragesic, a transdermal fentanyl
               patch, for the time period 1997-2006.

OBJECTIVES OF THE STUDY

                    The objectives of the research were to:

                    . Assess the revenue potential of Duragesic from 1997
                      through 2006.

                    . Identify key competitive factors in the current and
                      future market environment.

                    . Identify key drivers of and restraints to market growth.

                    . Analyze the market opportunity for the period 1997-2006.

RESEARCH METHODOLOGY

                    The information contained in this report was obtained
               through primary and secondary research.

                    Primary research included key discussions with:


                                      B-2
<PAGE>
 
                    . Executives at pharmaceutical companies participating in
                      the chronic pain therapy market

                    . Experts in the field of opiate therapy and chronic pain
                      treatment

                    Secondary sources used to obtain relevant support
               information included online data searches, trade journals, and
               syndicated publications.  In addition, IMS data encompassing
               sales of Duragesic and competing products for the period 1995-
               1997 were utilized.

                    Frost & Sullivan's initial approach to this project entailed
               in-depth interviews with experts in the field of chronic pain
               treatment.  In addition, executives at companies involved in the
               intractable pain market were interviewed to assess current and
               future market trends.

                    Following the initial phase of research, an in-depth
               analysis of the available information was done to develop a clear
               assessment and forecast of the market.

KEY FINDINGS

                    The key findings are as follows:

                    . For a scenario in which a second transdermal product does
                      not emerge on the market, Duragesic is expected to
                      continue to experience substantial growth throughout the
                      forecast period.  This growth will be due to increased
                      penetration into an expanding market, increased pricing,
                      and increased acceptance in key foreign markets.

                    . If a second product emerges on the market, in order to be
                      competitive, a company would need to undercut the price of
                      Duragesic.

                    Expanded market penetration should contribute to Duragesic's
               revenue growth.

DURAGESIC REVENUE FORECASTS

MARKET DEFINITION

                    Intractable pain is pain in which the cause cannot be
               removed or otherwise treated, and no relief or cure has been
               found.  Chronic pain is pain that persists for greater than one
               month beyond the course of an illness or injury, pain that
               continues sporadically over the span of years, or pain associated
               with a long-term disease such as cancer.

                    For the purposes of this project, the chronic pain market is
               defined as the population of people with cancer pain (malignant)
               and neuropathic pain (nonmalignant).  In 1997, the nonmalignant
               pain market totaled approximately 700,000 patients.  The total
               malignant chronic pain market was estimated to encompass 200,000
               patients.

                    The total value of the market is defined by the combined
               revenues generated by the following products: Duragesic, MS
               Contin, Oramorph, IR Morphine, Demerol, Dilaudid, and Kadian.  In
               1997, worldwide sales of Duragesic reached approximately $254.6
               million.  Approximately 80 percent of revenues were generated
               from U.S. sales.

Increased Penetration
of Duragesic into the Chronic Pain Market

                    A key component of future revenue growth will probably be a
               shift in the perception of opioid therapy.  According to leading
               experts in the field of opioid therapy, the market landscape in
               the United States is ripe for a revolution in how and for whom
               narcotic analgesics are prescribed.  A combination of regulatory,
               societal, and marketing factors will act in favor of
               liberalization in the use of these products.  This should result
               in an increase in prescribing patterns across indications
               (chronic cancer pain, neuropathic pain, and acute pain).

                    According to industry experts, regulatory changes and the
               effect of these changes on the medical community and society
               should instigate a shift in market dynamics.  Recent industry
               literature, position statements by patient advocacy
               organizations, and statements by the FDA have all focused on the
               inadequate treatment many pain patients receive in their final
               days of life as well as throughout their lifetime.  This trend is
               indicative of a significant change emerging in how these drugs
               are perceived.

                    Current misconceptions regarding tolerance and addiction
               prevent increased penetration of these products into the chronic
               pain market, specifically for chronic nonmalignant pain.  As
               experts and scientists continue to highlight the clinical
               pharmacological reality, these products will become less
               stigmatic.

                    In addition, the industry's continued study into the use of
               pain medication in nonmalignant pain patients should prove highly
               beneficial to the future market.  As scientific knowledge on the
               use of opioid therapy in this population of patients grows,

                                      B-6
<PAGE>
 
               industry participants, which have shown clinical effectiveness in
               this population, are expected to gain the approval to actively
               and aggressively market these products for nonmalignant pain
               indications.  An increase in marketing efforts directed at a end
               users currently undertreated is expected to correlate directly to
               an increase in the total number of prescriptions dispensed.

                    The growing use of Duragesic in the treatment of
               nonmalignant pain will be an integral component in the future
               sales growth of the product.  According to industry sources,
               approximately 700,000 patients suffer from neuropathic pain in
               the United States.  Unlike chronic cancer pain patients, these
               individuals are expected to live a typical life span, thus
               ensuring long-term annuity for companies.

                    The combination of a shift in perception, aggressive
               marketing, actions taken by patient advocacy groups, and trends
               to establish guidelines for the use of these products are
               expected to result in an increase in penetration of opioid
               therapy in the total pain population.

Increasing Acceptance of Duragesic
in the Following Key Foreign Markets: Spain,
Japan, Germany, United Kingdom, Italy, and France

                    The successful launch of Duragesic into key foreign markets
               is expected to contribute to a healthy growth pattern in the
               future.  Although some markets are highly profitable, in general,
               foreign markets do not generate revenues comparable to those of
               the U.S. market.  In many foreign markets, the industry cannot
               demand a price premium because of economic or regulatory factors.

                                      B-7
<PAGE>
 
                    Key markets in western Europe that do command price premiums
               include Germany and England.  As such, a large portion of future
               market growth will depend on these countries.  Other markets that
               are expected to prove profitable are Spain, Japan, Italy, and
               France.  The forecast model estimates that Duragesic will be
               launched into the Japanese market in 2001.

Price Increase of Duragesic

                    Based on historical trends, an increase in the price of
               Duragesic has been incorporated in the market forecast.  This is
               translated as an increase in the average price per year for
               treatment with Duragesic.  Because of a lack of direct
               competition in the form of a second transdermal patch or
               comparable delivery system, the price in relation to demand is
               inelastic (based on calculations made from historical demand and
               price increases).

                    Price elasticity allows companies to predict the effect of
               price on demand (and thus, unit sales).  It is defined as the
               sensitivity of demand with respect to price.  Inelastic
               translates into demand that is relatively unresponsive to price.
               Conversely, an elastic demand translates into demand that
               fluctuates greatly with price changes.  Factors that determine
               price elasticity include whether the necessity of the good and
               the availability of substitute products.  It is believed that the
               consumer (hospitals, private physicians, and managed care
               organizations) will accept price increases of 1.0 to 3.5 percent
               throughout the forecast period without significant correlating
               changes in demand.

Shifts in the Future Competitive Environment

                    An increase in the future competitive environment has also
               been integrated into the forecast model.  Although only one
               product is expected to have a significant impact on the market
               during the forecast period, this factor must be included in
               future predictions of market growth.

               Factors likely to contribute to market trends for this scenario
               include a change in market dynamics, reimbursement issues, and
               effects on foreign markets.

                    The following key analytical factors were utilized to
               determine the effect of a second product on the Duragesic
               revenues.

Creation Market

                    Because of the changing environment in the United States,
               the net number of individuals treated with opioid therapy is
               expected to increase in the future.  (This factor is discussed in
               the market opportunity assessment section of the first scenario).
               The expanding market, due to the growing penetration of opioid
               therapy in an undertreated population, will result in a creation
               market.

                    This new market opportunity will allow for competition to
               expand market revenues, despite a loss of prescription share due
               to increased competition.  This mechanism will reflect positively
               on Duragesic sales despite the emergence of a second transdermal
               patch.

                    An example of this dynamic occurred in the pharmaceuticals
               market in the early 1990s.  Prozac (marketed by Eli Lilly),
               launched in 1988, established a new class of products for the
               treatment of depression.  The product is a selective serotonin
               re-uptake inhibitor (SSRI).  The superior nature of the product
               in relation to other available products, combined with five years
               of market exclusivity, generated $880 million in revenues in the
               United States by 1993.

                    In 1993, the launch of Zoloft, Pfizer's SSRI changed a
               virtual monopoly into a competitive marketplace.  In addition,
               Zoloft was launched at a price below that of Prozac, thus
               significantly increasing the competition for Eli Lilly.

                                     B-10
<PAGE>
 
                    At the time Zoloft was launched, the market for a depressive
               was expanding because of a growing recognition of the disorder.
               This resulted in an increase in the population of potential
               users.  Although two equivalent drugs were available on the
               market, the size of the market had expanded significantly,
               leaving room for both competitors to increase penetration.
               Therefore, Zoloft gained a novel end-user population (a creation
               market) instead of converting patients already on Prozac.  Due to
               the market expansion, both companies were able to grow revenues
               significantly.

Pricing Strategy

                    To compete in a market already established and dominated by
               Duragesic, an emerging product would be forced to compete on the
               variable of price.  It is highly unlikely that an emerging
               product, priced equivalently, would be able to adequately compete
               with Duragesic after nine years of market exclusivity.  Because
               of this "head start," Duragesic will have the advantage of an
               already established distribution network; a strong, aggressive,
               and knowledgeable sales and marketing team; and most importantly,
               a high level of brand loyalty.

                    To compete with a solid product marketed globally, a second
               transdermal patch would most likely be forced to undercut
               Duragesic in price.  Based on the pricing of generic drugs in the
               pharmaceuticals industry, a second transdermal patch may be
               priced as much as 20 to 30 percent below Duragesic's price.  A
               product that is the only generic competitor to a branded
               pharmaceutical will undercut the branded product price by a
               minimal amount, approximately 20 percent.  As more generic
               products are launched and begin to compete in the market, generic
               manufacturers will further drop their prices.

Substitution at the Pharmacy Level

                    A key market dynamic that allows generic manufacturers to
               slightly undercut the branded competition is substitution at the
               pharmacy level.  Although a physician may prescribe the branded
               product, upon filling the prescription, a pharmacist may
               substitute a generic version.  This often occurs as a cost-
               cutting measure.

                    Substitution at the pharmacy level can be also done between
               two branded products if the substituted product is given an AB
               rating.  This rating, given by the FDA, denotes that these
               products are similar enough to be considered bio-equivalent.  If
               a second transdermal patch were to emerge and gain approval as
               bio-equivalent to Duragesic, substitution at the pharmacy level
               would be a highly plausible outcome.

                    An example of this occurred in the attention deficit
               disorder (ADD) market.  For years, pharmacological treatment of
               this disease was dominated by Ritalin (generic name
               methylpenidate).  Ritalin, the branded product, is marketed by
               Novartis.  Currently, one generic competitor exists--Medeva--with
               the product methylpenidate.  Methylpenidate is priced
               approximately 35 percent below Ritalin (based on the 1997 Redbook
               price).

                    According to industry sources, although Novartis continues
               to dominate in market share owing to its high price premium, the
               company is clearly losing in prescription share.  Industry
               sources claim that even though 80 percent of the prescriptions
               written are for Ritalin, less than 70 percent of the
               prescriptions dispensed are the branded product.  This is due to
               generic substitution occurring at the pharmacy level.

                                     B-12
<PAGE>
 
                    To substitute a generic product for a branded product, or
               potentially a branded product for an equivalent branded product,
               the pharmacist must ask the consumer for permission.  The main
               factor favoring the dispensation of the lower-priced product is
               the individual's managed care organization.  Although a consumer
               does have a choice as to the product dispensed, the HMO plan may
               only cover the lower-priced drug, therefore encouraging the
               individuals to choose it or pay for the difference themselves.

Effect of Second Product
on Foreign Markets Is Not Substantial

                    A second transdermal patch is not expected to be launched
               immediately on the global market without first generating
               substantial revenues in the United States.  In addition, because
               of the lengthy approval process in many countries, a 2000 launch
               in foreign markets is highly unlikely.  Because of these factors,
               the extent of Duragesic's market share loss in foreign markets
               during the forecast period will probably be insignificant.

MARKET DRIVERS

                    The following factors were determined to be key drivers of
               the future market.

Regulatory Changes

                    According to industry experts, state governments in the
               future are expected to establish guidelines and laws for use
               opioids that do not impede medical practice.

                                     B-13
<PAGE>
 
Perceptual Shift

                    The anticipated favorable shift in the perception of opioid
               therapy, within the medical community and within society at
               large, should contribute to increased use of such therapy.

Advocacy Groups

                    Action by patient advocacy groups continue to elevate the
               undertreatment of chronic pain as a significant medical issue.
               The groups are essential components of the market because they
               spur regulatory action by governmental bodies.

Increased Marketing

                    Based on the solid scientific results of industry studies,
               opioid therapy is expected to gain approval to aggressively
               market for nonmalignant pain indications.  This is expected to
               boost penetration into a population that is currently
               undertreated.

Potential for Long-Term Annuity

                    As opioid therapy becomes more widely used to treat
               nonmalignant chronic pain, industry participants will gain long-
               term annuity, since many of these patients will likely live
               typical life spans.

MARKET RESTRAINTS

                    The following factors were determined to be key restraints
               to market growth.

Gradual Process of Overcoming Misconceptions

                    Currently, misconceptions regarding the addictive nature of
               opioid analgesics inhibit greater penetration of these products
               into the population of chronic pain patients.  For many members
               of the medical community as well as patients, opioid analgesics
               are thought to be associated with a high risk of addiction.

                    According to experts in the field of opioid therapy,
               physical dependency is often used synonymously with addiction,
               leading to confusion.  As with many other types of drugs,
               physiological changes in the body lead to withdrawal symptoms
               when individuals cease using opioid narcotics.  However, this is
               not equivalent to addiction.  In patients with no history of
               addiction, this issue should not be considered a risk in the
               management of their pain.  Although addiction is not considered
               by knowledgeable physician and patients as a risk, it is a factor
               that impedes use among less knowledgeable individuals.

                    Although a change in the view of the addictive nature of
               these products is expected, the process will be gradual,
               occurring over a five to ten years.  Thus, an immediate
               substantial increase in the use of opioid therapy is unlikely.

Increased Competition in the Future Market

                    The launch of an innovative product offering pain relief
               with few side effects is expected to increase the competition in
               the market, and projected to significantly affect the chronic
               neuropathic pain market.

COMPETITIVE ENVIRONMENT

Analysis of Present Market Environment

                    The current narcotic analgesics market is dominated by seven
               participants, which can be stratified into two tiers of
               competition.  Duragesic and MS Contin control the first tier of
               competition.  Based on clinical pharmacology, Kadian and Oramorph
               can be considered first-tier competitors, although neither
               product commands as much prescription share as Duragesic or MS
               Contin.  Differences in overall equivalency, ease of use,
               duration of action, and analgesic effect differentiate these top
               competitors from second-tier products such as Dilaudid, Demerol,
               and IR morphine.

                    Second-tier products lack several key competitive advantages
               that prevent them from tightening the competitive environment.
               The major disadvantages are:

                    . Comparatively short duration of action

                    . Less controlled release of opioid

                    . Oral dosages are less effective than parenteral
                      counterparts

                    The shorter duration of action is a major weakness of
               second-tier opioid analgesic drugs.  This limitation prevents
               Demerol (meperidine) from being considered a viable product for
               relieving chronic pain (instead of one more appropriate for acute
               pain).  Furthermore, decreased duration of action prevents all
               second-tier competitors from gaining a position of strength in
               the total chronic pain market, since they are more suitable for
               various niche indications.

                    First-tier products also offer key advantages in ease of
               use, propelling these products into a different class.  The

                                     B-16
<PAGE>
 
               limitation of current second-tier products is expected to
               continue to prevent them from being a substantial competitive
               factor to Duragesic.

                    Of the first-tier competitors, MS Contin and Oramorph are
               similar products offering an oral product administered every 8 to
               12 hours.  Kadian competes directly with these two standard
               treatments, offering a product administered every 24 hours.
               Within the first tier of competition, the following factors
               continue to effect market dynamics:

     RAPID DOSE TITRATION

                    Duragesic is limited in one arena: it is not suitable for
               rapid dose titration.  If patients suffer a constant level of
               pain, the limitation is not significant, but for patients with
               rapid increases in pain intensity, Duragesic is not a suitable
               option.  Furthermore, in the future, opioid therapy is expected
               to expand as a treatment of severe acute pain.  Because of the
               limited time of opioid use in these patients, Duragesic will be
               unable to capitalize on this trend.

     EASE OF ADMINISTRATION

                    Ease of use remains a significant factor that continues to
               drive Duragesic sales.  The convenience of the transdermal
               administration mode is unmatched by other products on the market.
               Although oral morphine offers ease of use, the oral formulation
               of morphine sulfate is not as potent as the intravenous
               formulations.

     CONTINUED AGGRESSIVE MARKETING OF KADIAN

                    Kadian, the newest entrant into the opioid therapy market,
               is expected to continue to impact market dynamics and 

                                     B-17
<PAGE>
 
               modify the competitive environment. As marketing of Kadian
               continues and the product gains prescription share, oral morphine
               sulfate is expected to experience the biggest decline in sales.
               Kadian intensifies the competitive environment for Duragesic,
               offering a product with a significantly long duration of action.
               However, prescription share is not forecast to be significantly
               affected by this product.

Analysis of Future Market Environment

                    Research and development efforts in the narcotic analgesic
               market are focused on delivering equivalent pain relief to
               current marketed products while simultaneously diminishing side
               effects.  Figure 2-3 shows the products in development for the
               treatment of chronic pain in the narcotic analgesic
               pharmaceuticals market.

                    Strategies for delivering novel products tend to take one of
               two paths: Companies are developing new administration modes for
               already used compounds, or they are developing new compounds that
               display their potency through a variant mechanism.  It is the
               latter of the two strategies that, if successful, may be the
               greatest threat to Duragesic sales in the future.

                    The majority of products listed in Figure 2-3 will not have
               a significant, if any, impact on the future market for Duragesic.
               Products early in the developmental process are not expected to
               appear on the market until 2004 or 2005, if at all.  Many
               products in the later stages of development are not believed to
               have significant benefits or advantages that will threaten
               Duragesic's market share.  The exception to this is Ziconotide

                                     B-19

               (formerly SNX-111), which is currently completing Phase III
               clinical trials.

                    Ziconotide, in development by Neurex Corporation (Menlo
               Park, California), is a synthetic copy of a natural neurotoxin
               taken from cone snail venom.  The compound, delivered through an
               infusion pump, is a selective neuron specific calcium channel
               blocker (a neurochemical pathway through which pain signals
               travel to the brain).

                    The advantages and disadvantages of this product compared to
               Duragesic are listed in Figure 2-4.  The key advantage of
               Ziconotide over Duragesic is the lack of side effects.  It
               appears that use of Ziconotide is not associated with euphoria or
               mental confusion, which tend to accompany morphine-based
               analgesics.  This will prove a crucial marketing advantage, since
               individuals and physicians alike will favor a compound that
               relieves pain without diminishing the patient's mental capacity.

                    The company plans to file an new drug application in
               September 1998 with the FDA.  The initial label indication that
               Neurex will pursue is for use in patients who have failed all
               other forms of opiate therapy.  According to Neurex, this
               population consists of approximately 270,000 malignant and
               neuropathic pain patients.  The company estimates that
               approximately 10 percent of the 700,000 neuropathic pain patients
               (70,000) and 200,000 cancer pain patients are not receiving
               adequate pain relief from current treatments.

                    Because there are no existing treatment options for these
               patients, according to FDA guidelines, Ziconotide is eligible to
               be fast-tracked through the approval process.  Therefore, the
               launch date for this drug is estimated to be the first quarter of
               2000.

                    Although Ziconotide will not benefit immediately from a
               broad indication and thus not appear to be a competitive factor
               for Duragesic, "off-label" use is a factor.  The key benefits of
               Ziconotide are strong incentives for physicians to prescribe the
               drug to patients who wish to remit their chronic pain, without
               becoming debilitated by morphine-induced side effects.

                    The main disadvantage expected to inhibit the widespread
               success of Ziconotide is the product's delivery method.  The only
               intrathecal product currently on the market is Infumorph by
               Elkins Sinn.  It is not widely used and appears to be an option
               for treatment only after intravenous and oral therapy have
               failed.  The inconvenience of an infusion pump will serve as a
               restraint to penetration of Ziconotide.  Furthermore, the cost
               may also retrain the use of Ziconotide, which will be priced at
               approximately $3,500 to $5,000 per year.

                                ---------------

     ALZA Development Corporation ("ADC"), a wholly owned subsidiary of ALZA
Corporation ("ALZA"), and the general partner (the "General Partner") of ALZA
TTS Research Partners, Ltd., a California limited partnership (the
"Partnership") wishes to advise the holders of Class A Limited Partnership
Interests and the Class B Limited Partnership Interest that on
____________, 1998, the General Partner exercised its option to purchase all of
the issued and outstanding Limited Partnership Interests (the "Purchase Option")
as provided in the Agreement of Limited Partnership (the "Agreement of Limited
Partnership"). The Class A Limited Partnership Interests and the Class B Limited
Partnership Interest are referred to collectively in this Notice to Limited
Partners (the "Notice") as the "Limited Partnership Interests".

     The purchase price for all issued and outstanding Limited Partnership
Interests is $91,176,592.48 (the "Purchase Price") or $27,216.21 per Class A
Limited Partnership Interest and $4,084,720.48 for the Class B Limited
Partnership Interest. ALZA intends to contribute to ADC the amount of cash
necessary to exercise the Purchase Option, which contribution ALZA intends to
finance with its cash and marketable securities. The closing (the "Closing") of
the purchase of the Limited Partnership Interests will take place on _______,
1998 (the "Closing Date"). Upon the Closing, the General Partner will forward to
each holder of record of a Limited Partnership Interest as of the Closing Date a
check equal to such holder's pro rata interest in the Purchase Price.

                                 ------------

     This Notice relates to the exercise by ADC of its option to purchase all
issued and outstanding Limited Partnership Interests of the Partnership. ADC is
the General Partner of the Partnership and is a wholly owned subsidiary of ALZA.
This Notice is being given by ALZA and ADC.

                                SPECIAL FACTORS
                                ---------------

Purpose.

     The purpose of this transaction is for ALZA, through ADC, to acquire all
rights, on an exclusive basis, to products (the "Partnership Products") for 
which development was funded by the Issuer under its Research and Development 
Agreement (the "Development Agreement") with ALZA. ALZA believes that it
is in the best interests of ALZA and ALZA's stockholders to exercise the
Purchase Option at this time. ALZA has worldwide licenses, including the right
to sublicense, to make, use and sell (i) a transdermal fentanyl product sold
in the United States under the name Duragesic(R) and (ii) a transdermal
testosterone product sold under the name Testoderm(R). Such licenses are
currently exclusive; however, ALZA's exclusive rights with respect to
Testoderm(R) and Duragesic(R) would end on July 26, 1998 and December 4, 1998,
respectively. Because ALZA's exclusive rights are limited in duration, ALZA
believes that exercising the Purchase Option is the most effective and
comprehensive method of acquiring continued exclusive rights to Testoderm(R),
Duragesic(R) and other Partnership Products. In addition, because ALZA's
obligations to pay royalties to the Partnership under the licenses for
Testoderm(R) and Duragesic(R) will terminate upon exercise of the Purchase
Option, ALZA will benefit by retaining the full royalty received on sales of
Duragesic(R) and the full sales margin on Testoderm(R).

     The structure of the transaction is in accordance with the terms of the
previously granted Purchase Option as set forth in the Limited Partnership
Agreement. The transaction is being undertaken at this time because of the
timing of the expiration of ALZA's exclusive rights described above. ADC and
ALZA did not consider alternative means to accomplish the transaction because of
the previously granted Purchase Option.

1997 Tender Offer.

     On November 20, 1997, PharmaInvest, L.L.C. ("PharmaInvest") on behalf of
Pharmaceutical Royalties L.L.C., Pharmaceutical Royalty Investments Ltd. and
Pharmaceutical Partners L.L.C. ("Pharmaceutical Partners") made an unsolicited
tender offer (the "Tender Offer") to purchase up to 1,400 Class A Limited
Partnership Interests, representing approximately 44% of the total outstanding
Class A Limited Partnership Interests, for cash consideration per Class A
Limited Partnership Interest of $12,000.  In response to the Tender Offer, the
General Partner filed a Schedule 14D-9 (the "Schedule 14D-9") with the
Securities and Exchange Commission (the "Commission"), in which the General
Partner expressed no opinion with respect to the Tender Offer to the holders of
the Class A Limited Partnership Interests and stated that the General Partner
would remain neutral as to whether the Limited Partners should tender or refrain
from tendering their Class A Limited Partnership Interests. In its letter to the
Limited Partners advising them of its neutrality with respect to the Tender
Offer, the General Partner drew the attention of the Limited Partners to certain
facts, including, (i) the dates on which ALZA's exclusive rights with respect to
Duragesic(R) and Testoderm(R) were scheduled to expire, (ii) the General
Partner's expectation of the growth of sales of Duragesic(R) and (iii) the
report of Securities Pricing and Research, Inc., an independent appraisal firm
("SPAR"), estimating that the rounded net asset value and fair market value of a
Class A Limited Partnership Interest as of December 31, 1996 were $21,200 and
$15,900, respectively. None of ADC, ALZA or the Partnership has any affiliation
with SPAR, nor does any of them endorse the report prepared by SPAR (the "SPAR
Report"). In addition, neither the General Partner nor the Partnership engaged
SPAR to prepare the SPAR Report or participated in the preparation of the SPAR
Report. The SPAR Report was not related to the Tender Offer and is not related
to the Purchase Option.

     Also on November 20, 1997, Pharmaceutical Partners, an affiliate of
PharmaInvest,  in a letter addressed to ALZA, set forth its views about the
Purchase Option and its effects on the Limited Partners, the Partnership, the
General Partner and ALZA.  In connection with the Partnership's consideration
and evaluation of the Tender Offer, ALZA, on December 2, 1997, advised the
Partnership of the matters raised in Pharmaceutical Partners' letter to ALZA and
informed the Partnership of ALZA's position regarding such matters.  A copy of
such letter was, with ALZA's permission, included as an exhibit to the Schedule
14D-9 and sent to the holders of the Limited Partnership Interests.  On January
16, 1998, PharmaInvest amended its offer by increasing the purchase price of
each Class A Limited Partnership Interest from $12,000 to $13,200.  In
connection with the increase in the purchase price, the General Partner filed an
amendment to its Schedule 14D-9 stating that the General Partner continued to
express no opinion to the holders of the Class A Limited Partnership Interests
and that the General Partner would continue to remain neutral as to whether the
Limited Partners should tender or refrain from tendering their Class A Limited
Partnership Interests.  In addition, the General Partner informed the Limited
Partners that in reaching its 

                                      D-4
<PAGE>
 
conclusion with respect to the Tender Offer, the General Partner had taken into
account (i) that SPAR had reduced its estimates of the rounded net asset value
and fair market value of the Class A Limited Partnership Interests as of
December 31, 1996, and (ii) the General Partner's expectation of the growth of
sales of Duragesic(R). On February 2, 1998, PharmaInvest announced that the
Tender Offer had expired and that 72 Class A Limited Partnership Interests were
tendered in connection with the Tender Offer.

     As described above, in November 1997, PharmaInvest made the Tender Offer.
In the last fiscal year, PharmaInvest contacted the General Partner to make it
aware of its possible interest in the Partnership as an investment opportunity.
PharmaInvest sent additional letters on July 11 and 17, 1997 continuing to
express its interest in the Partnership.  In October 1997, PharmaInvest had a
conversation with the General Partner reiterating its interest in the
Partnership.  Following the conversation, PharmaInvest acquired two Class A
Limited Partnership Interests, and on October 22, 1997 made a written request to
receive a list of names and addresses of Limited Partners (the "List").
PharmaInvest received the List on November 2, 1997 and commenced the Tender
Offer on November 20, 1997.

Consequences.

     As a result of the transaction described herein, the Partnership will
terminate as a limited partnership and the General Partner will take all
appropriate and necessary actions to suspend the Partnership's public reporting
obligations and to wind up the affairs of the Partnership in accordance with
California law. The General Partner will continue as a wholly owned subsidiary
of ALZA. For federal income tax purposes the Partnership will be treated as
terminating on the date of the transaction and as distributing all of its
assets, subject to all of its liabilities, to the General Partner on that date.
The Partnership will not have taxable gain or loss as a result of the
transaction described herein.

                                      D-5
<PAGE>
 
     The transaction described herein will cause each Limited Partner to dispose
of its Limited Partnership Interests for consideration equal to such holder's
pro rata share of the Exercise Price.  The following discussion sets forth
- --------                                                                  
general federal income tax considerations under the Internal Revenue Code of
1986, as amended (the "Code") for the Limited Partners with respect to cash
received by the Limited Partners for the Limited Partnership Interests. This
discussion is intended only to provide general information to the Limited
Partners that are subject to United States federal income tax; it may not
address all relevant federal income tax consequences to such persons or to other
categories of the Limited Partners (e.g., foreign persons, dealers in
                                    ----
securities, and persons that are exempt from federal income tax). This
discussion is based upon present federal income tax laws and does not attempt to
anticipate changes, including changes in tax rates, that may be made under
currently pending legislative proposals. This discussion assumes that the
Limited Partnership Interests were at all relevant times capital assets of the
Limited Partners. This discussion does not address state, local or foreign tax
considerations. ALL LIMITED PARTNERS ARE URGED TO CONSULT THEIR OWN TAX
ADVISORS.

     Except as described below, the holder of a Limited Partnership Interest
should generally have a capital gain or loss due to ADC's exercise of the
Purchase Option equal to the difference between (i) the amount of cash received
and (ii) the holder's basis in the Limited Partnership Interest.  A Limited
Partner's basis in a Limited Partnership Interest is the Limited Partner's
initial purchase price decreased by any partnership deductions taken by the
Limited Partner and any cash distributed by the Partnership to the Limited
Partner and increased by the Limited Partner's share of the Partnership's
income. Under current law, capital gain or loss will be: (a) long-term if the
Limited Partnership Interest has been held at least 18 months at the time the
Purchase Option is exercised, (b) mid-term if the holding period is more than
one year but less than (or equal to) 18 months, and (c) short term if the
holding period is a year or less. Under Section 751 of the Code, the difference
between the portion of the cash received by the holder that is attributable to
"unrealized receivables" and "inventory" of the Partnership (together, "Section
751 Property") over the portion of the holder's adjusted tax basis in the
Limited Partnership Interest allocable to Section 751 Property will be treated
as ordinary income or loss, rather than capital gain or loss. Although this
conclusion is not entirely free from doubt, ADC believes that the only
"unrealized receivables" of the Partnership should be the amount, if any, of
accrued, but unpaid royalties under ALZA's licenses to Duragesic(R) and
Testoderm(R). Treasury regulations require each person who transfers an interest
in a partnership possessing Section 751 Property to file a statement with such
person's tax return reporting the transfer and certain other information
relating thereto. Limitations may apply to deduction of capital loss.

     To the extent that any holder of a Limited Partnership Interest has not
provided an appropriate taxpayer identification number on IRS Form W-9 or a
substitute therefor, the holder may be subject to backup withholding by ALZA or
ADC.

     The Purchase Price will be amortized by ALZA over a number of years.

Fairness.

     Each of ADC and ALZA reasonably believes that the transaction described
herein is fair to the Limited Partners.  None of ALZA's or the General Partner's
directors dissented to or abstained from voting on such transaction.

     Each of ADC and ALZA has based its respective belief that the transaction
is fair to the holders of the Limited Partnership Interests on the fact that the
Limited Partners were fully aware of the Purchase Option, which was an essential
economic term of the Limited Partnership Interests, when they purchased their
Limited Partnership Interests.  The prospectus, pursuant to which the Limited
Partnership Interests were offered and sold, fully described the Purchase
Option.  The Purchase Option, which is contained in the Limited Partnership
Agreement, was also publicly filed with the Commission.  The Limited Partners
were also advised of the Purchase Option in each Form 10-K and each recent Form
10-Q public filing made by the Partnership with the Commission.  In addition,
the Limited Partners were reminded of the Purchase Option in connection with the
Tender Offer and in evaluating whether or not to tender their Limited
Partnership Interests in the Tender Offer.  Accordingly, the Purchase Option was
present in the initial public sale, was disseminated in the Partnership's
charter documents and was discussed in the Partnership's periodic filings.  As a
result, every Limited Partner received substantial notice as to the terms of the
Purchase Option prior to making any investment decision with respect to the
Limited Partnership Interests.  In addition, in its most recent filings the
Partnership has indicated that ALZA's exclusive rights with respect to 
Duragesic(R) and Testoderm(R) would expire soon and
that such expiration could lead to the exercise of the Purchase Option.

     In connection with its decision whether to exercise the Purchase Option, in
February of 1998 ALZA commissioned Frost & Sullivan, an independent market
research firm ("Frost & Sullivan"), to prepare a market research report (the
"Report") of revenue forecasts for Duragesic. ALZA took into account the
information contained in the Report in deciding whether the exercise of the
Purchase Option was in the best interests of ALZA and ALZA's stockholders;
however, because the Report did not assess the fairness of the exercise price of
the Purchase Option, neither ALZA nor ADC considers that the Report is relevant
with respect to the fairness of the transaction to the Limited Partners. ALZA
engaged Frost & Sullivan to prepare the Report because of Frost & Sullivan's
expertise with respect to analyzing sales and marketing information and trends
of product sales in the pharmaceutical industry. Prior to engaging Frost &
Sullivan, ALZA contacted several other market research firms, but chose Frost &
Sullivan because of its availability and experience. ALZA has engaged Frost &
Sullivan for other market research engagements from time to time and has paid
normal service fees in connection with such engagements. The objectives of the
Report were to (i) assess the revenue potential for Duragesic(R) during the
period from 1997 to 2006, (ii) analyze the market opportunity for the same
period, (iii) identify key

                                      D-7
<PAGE>
 
competitive factors in the current and future market environment and (iv)
identify key drivers of and restraints to market growth. After research using
both primary and secondary sources, the key findings provided by the Report were
(a) if a second transdermal product does not emerge on the market, Duragesic(R)
is expected to continue to experience substantial growth throughout the forecast
period due to an increased penetration into an expanding market, increased
pricing and increased acceptance in key foreign markets, and (b) if a second
transdermal product emerges on the market, in order to be competitive, a
competitor would need to undercut the price of Duragesic(R). A copy of the
Report is available for inspection and copying at the principal executive
offices of ALZA during its regular business hours by any interested Limited
Partner or his or her representative who has been so designated in writing. A
copy of the Report will be transmitted by ALZA to any interested Limited Partner
or his or her representative who has been so designated in writing upon written
request and at the expense of the requesting Limited Partner.

     The exercise of the Purchase Option and the consummation of the
transactions thereunder do not require approval of the Limited Partners.

     No director of ALZA or the General Partner has retained an unaffiliated
representative to act solely on behalf of the Limited Partners.  As a limited
partnership, the Partnership does not have any directors.  Each director of the
General Partner is an officer of the General Partner and an employee and officer
or vice-president of ALZA.

Securities of the Partnership.

     The exact title of the class of security which is the subject of this
Notice is the Class A Limited Partnership Interests of ALZA TTS Research
Partners, Ltd.  As of March 31, 1998 (the most recent practicable date), there
were (i) 3,200 Class A Limited Partnership Interests and (ii) one Class B
Limited Partnership Interest issued and outstanding.  As of March 31, 1998 (the
most recent practicable date), there were approximately 1,972 holders of record
of Class A Limited Partnership Interests and one holder of record of the Class B
Limited Partnership Interest.  The rights of the Class A Limited Partnership
Interests and the Class B Limited Partnership Interest are the same except that
the holder of the Class B Limited Partnership Interest has a right to consult
with ADC with respect to certain matters.

     There is no established trading market for the Limited Partnership
Interests.

     The Partnership has not paid any dividends on the Class A Limited
Partnership Interests or on the Class B Limited Partnership Interest in the past
two years, except for distributions made to the holders of Limited Partnership
Interests pursuant to the terms of the Limited Partnership Agreement.

Past Contracts, Transactions or Negotiations.

     As part of its initial organization and funding, the Partnership granted
ALZA an option (the "License Option") to acquire a license for the Partnership
Products. In 1990, ALZA exercised its License Option for two Partnership
Products: (i)

                                     D-13
<PAGE>
 
Duragesic(R) and (ii) Testoderm(R). Under each license, ALZA makes payments to
the Partnership based on ALZA's and its affiliates' and sublicensees' sales of
the licensed product. ALZA paid the Partnership $2,644,646, $8,776,814 and
$6,265,401 for the three months ended March 31, 1998 and the years ended
December 31, 1997 and December 31, 1996, respectively, of which approximately
97.5%, 95% and 96% were attributed to Duragesic(R) for the three months ended
March 31, 1998 and fiscal 1997 and 1996, respectively.

     The administrative, accounting, contract management and record keeping
services required by the Partnership have been provided in the past and are
currently being provided by ALZA and are billed to the Partnership at ALZA's
standard administrative services rate. The Partnership paid ALZA $18,835,
$105,512 and $86,548 for the three months ended March 31, 1998 and the years
ended December 31, 1997 and December 31, 1996, respectively.

Terms of Transaction.

     Pursuant to the terms of the Limited Partnership Agreement, ADC has the
Purchase Option which allows ADC to purchase all (but not less than all) of the
Limited Partnership Interests. The exercise price for exercise of the Purchase
Option is $120 million less an amount equal to all cash distributed to the
Limited Partners by the Partnership (the "Exercise Price").  As of the date
hereof, the Exercise Price is $91,176,592.48.  The Exercise Price will
be allocated among the Limited Partners based on their pro rata contributions.
                                                       ---------               
At the Closing, the holders of record of Class A Limited Partnership Interests
as of the Closing Date will receive $27,216.21 per Class A Limited Partnership
Interest (purchased in the original offering for $5,000 each) and the holder of
the Class B Limited Partnership Interest will receive $4,084,720.48 for its
Class B Limited Partnership Interest.  The Exercise Price will be paid by check
to each holder of the Limited Partnership Interests.

     In accordance with the terms of the Limited Partnership Agreement, the
Limited Partners are not required to take any steps to approve the exercise of
the Purchase Option or the consummation of the transactions pursuant to the
Purchase Option.  Title to the Limited Partnership Interests automatically vests
in ADC no later than 30 days after notice of the exercise of the Purchase Option
is given to the Limited Partners, upon payment of the purchase price for the
Limited Partnership Interests.  The Closing Date is _______________, 1998.

     Exercise of the Purchase Option will result in ADC owning all of the
Limited Partnership Interests. Upon purchase of all of the Limited Partnership
Interests by ADC, the Partnership will terminate as a limited partnership and
the General Partner will take all appropriate and necessary actions to suspend
the Partnership's public reporting obligations by filing a Form 15 with the
Commission and to wind up the affairs

                                     D-14
<PAGE>
 
of the Partnership in accordance with California law. ADC will continue as a
wholly owned subsidiary of ALZA. Although ALZA and ADC have no specific
intentions with respect to the operations of the business of the Partnership
following the exercise of the Purchase Option, ALZA and ADC intend to operate
the business of the Partnership in a manner best designed, in the judgment of
ALZA, to realize the benefit of that business to ALZA and its stockholders.

     ALZA intends to contribute to ADC the amount of cash necessary to exercise
the Purchase Option, which contribution ALZA intends to finance with its cash
and marketable securities.  All of the fees and expenses of the transaction will
be paid by ALZA.

Interests in Securities of Partnership.

     None of ADC, ALZA or any of their respective directors or officers own any
Limited Partnership Interests. ALZA is the sole shareholder of the General
Partner and each officer and director of the General Partner is an employee and
officer or vice-president of ALZA. As described in this Notice, the General
Partner may at any time, pursuant to the Purchase Option, purchase all of the
outstanding Limited Partnership Interests.

Contracts, Arrangements or Understandings with Respect to Partnership's
Securities.


     Article Seven of the Limited Partnership Agreement grants ADC the Purchase
Option. The Purchase Option states that ADC may purchase all (but not less than
all) of the issued and outstanding Limited Partnership Interests at any time
after January 1, 1987 and prior to dissolution of the Partnership.  ADC may
exercise the Purchase Option by mailing a notice of exercise to the Limited
Partners.

                      OTHER PROVISIONS OF THE TRANSACTION
                      -----------------------------------

     Appraisal rights are not afforded under applicable law in respect of the
exercise of the Purchase Option and none will be afforded.  Neither ALZA nor ADC
is aware of any rights available to objecting holders of the Limited Partnership
Interests under applicable law.

     None of ALZA, ADC or the Partnership is aware of any grant of access to
unaffiliated security holders to the corporate files of the Partnership or the
appointment of counsel or appraisal services for unaffiliated security holders
at the expense of the Partnership.
