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 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. 9 (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 to the Issuer. --------- 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. 10 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 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 margin on ALZA's sales of 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 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. 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. Pending federal legislation would reduce the holding period for long-term gain to one year. Limitations may apply to deduction of capital loss. 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 Issuer will have no "unrealized receivables" as of the date of the transaction described above. 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 (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 terms of the Purchase Option are contained in the Limited Partnership Agreement, which 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 (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).
