Crescendo shall request that ALZA or a third party perform the activities under each such Work Plan; provided, however, that ALZA's prior written consent shall be required for a third party to perform any activities that involve ALZA Technology or that could affect ALZA's rights under any agreement between ALZA and Crescendo or ALZA's rights as holder of the Class B Common Stock of Crescendo. Crescendo shall use diligent efforts to cause each third party other than ALZA (or a third party engaged by ALZA) to perform diligently the activities assigned it under a Work Plan. 3.2 Product Development - ALZA Obligations; Other ALZA -------------------------------------------------- Activities. Crescendo hereby engages ALZA to perform product identification, - ---------- evaluation, research, development and related activities in accordance with the tasks assigned to ALZA under the Work Plans accepted under Section 2, and to undertake such other activities as the parties may agree. ALZA diligently shall perform or cause to be performed such activities. In connection therewith, ALZA shall make available such of its scientific, engineering, manufacturing and other personnel, and shall take such steps as it deems necessary in order to perform its obligations in accordance with the terms hereof, but ALZA is not obligated to devote any specific amount of time or resources to activities hereunder.

The parties understand and acknowledge that ---------- it is difficult to predict accurately the activities that will be necessary to complete any Work Plan, including the Development Costs thereof, and that significant uncertainties exist in any product development effort. Crescendo and ALZA shall cooperate in good faith to devise mutually acceptable Work Plans for Product Development Programs, Technical Evaluations, candidate identification activities and such other activities as the parties may agree. ALZA and Crescendo shall review each such Work Plan from time to time, and with respect to a Work Plan for a Crescendo Product no less often than at the end of each stage of development, and shall revise each Work Plan as appropriate such that each Work Plan remains a best estimate of the work to be performed to complete the development objectives identified therein and of the Development Costs thereunder. Crescendo shall not be obligated to pay Development Costs in excess of those provided for in approved Work Plans, and ALZA shall not be obligated to perform work which would result in Development Costs exceeding those in approved Work Plans. 3.4 Consultation.

After such time as the License Option for a Crescendo Product in a - ------ country expires 7 unexercised as to such country, no additional Available Funds shall be expended for the development of such Crescendo Product for sale in such country. 3.8 Notices. ALZA shall notify Crescendo within three business ------- days after ALZA receives notice of clearance to market any Crescendo Product in any country. ALZA shall promptly notify Crescendo of the first commercial sale of a Crescendo Product, Developed Technology Product or Technical Evaluation Product in any country. 4.

The buy-out price shall be an amount equal to (i) 20 times (A) the payments made by or due from ALZA to Crescendo under Section 7.4 with respect to sales of such Developed Technology Product or Technical Evaluation Product, plus (B) such payments as would have been made by or due from ALZA to Crescendo if ALZA had not exercised any country-specific buy-out option with respect to such Developed Technology Product or Technical Evaluation Product, in each case, for the four calendar quarters immediately preceding the quarter in which the buy-out option is exercised, less (ii) any amounts previously paid to exercise any country- specific buy-out option with respect to such Developed Technology Product or Technical Evaluation Product. 11 7.6 Payments. Payments shown by each calendar quarter report -------- described in Section 5.3 to have accrued shall be due and payable on the date the report is due and shall be paid in United States dollars. Any and all taxes due or payable on such payments or with respect to the remittance thereof shall be deducted from such payments and shall be paid by ALZA to the proper taxing authorities, and proof of payment shall be secured and sent to Crescendo as evidence of such payment. The rate of exchange to be used in computing the amount of United States dollars due to Crescendo in satisfaction of payment obligations with respect to sales in foreign countries shall be calculated by converting the amount due in such foreign currency into United States dollars based on the rate for the purchase of United States dollars with such currency as published in the Wall Street Journal on the last business day of the calendar quarter for which payment is being made. 7.7 Certain Foreign Payments.
