performs research and development activities on behalf of
Crescendo directed toward the development of pharmaceutical
products; and
     WHEREAS, ALZA is marketing Doxil-Registered Trademark-

a program with the goal of receiving clearance by the FDA to

                                    AGREEMENT
                                    ---------

         NOW, THEREFORE, in consideration of the mutual covenants and conditions
contained in this Agreement, and for other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties hereto
agree as follows:

1.       PURCHASE AND SALE
         -----------------

         Upon the terms and subject to all of the conditions in this Agreement
and the performance by each of the parties of their respective obligations, the
Purchaser agrees to purchase from the Seller and the Seller agrees to sell and
deliver to the Purchaser on the Closing Date (as hereinafter defined), those of
Starting Point, L.L.C.'s assets which are not Excluded Assets (the "Purchased

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

         The Purchaser shall issue at the Closing (hereinafter define) 250,000
shares of its Rule 144 Common Stock, issued pursuant to Rule 506 of Regulation D
of the Securities Act of 1933, as amended (the "Purchase Price"). The Seller's
accounts payables and all other liabilities, through and including the Closing

<PAGE>

parties shall execute a hold harmless and indemnification agreement in favor of
each other for any and all claims that may arise as a result of (i) Seller's
ownership of Starting Point, L.L.C. prior to Closing in favor of Purchaser; and
(ii) Purchaser's ownership of Starting Point, L.L.C. from and after Closing in
favor of Seller. The Indemnification Agreements are attached hereto as Exhibit
"B".

         (a)      Piggyback Registration Rights:

                  (i) Notice of Registration. If Purchaser at any time proposes
to register any shares of its Common Stock under the 1933 Act whether or not for
sale for its own account, other than an offering primarily or exclusively to
employees and the registration form to be used may also be used for the
registration of the Shares (a "Piggyback Registration"), Purchaser shall at such
time notify Seller at least thirty (30) days prior to the filing of any
registration statement with respect thereto. Upon the receipt of a written
request of the Seller made within ten (10) days after such notice (which request
shall specify the number of Shares intended to be registered), Purchaser will
use its best efforts, subject to the limitations set forth below, to include in
such registration statement the number of shares sought to be registered by the
Seller. Each such request shall also contain an undertaking from the Seller to
provide all such information and material and to take all actions as may be
required in order to permit Purchaser to comply with all applicable federal and
state securities laws.

                  (ii) Underwriting. Notwithstanding any other provisions of
this Section 2, in the case of an underwritten public offering, if the managing
underwriter determines that market factors require limitation of the number of
shares to be underwritten, the managing underwriter may limit the number of
shares to be included in such Piggyback Registration, but to no greater
percentage than any other shareholder is limited.

                  (iii) Indemnification. To the extent permitted by law, the
Purchaser will indemnify Seller and each person controlling Seller within the
meaning of Section 15 of the Securities Act and each underwriter, if any, of the
Purchaser's securities, with respect to any registration, qualification or
compliance which has been effected pursuant to this Agreement, against all
expenses, claims, losses, damages or liabilities as incurred (or actions in
respect thereof), including any of the foregoing incurred in settlement of any
litigation, commenced or threatened, arising out of or based on any untrue
statement (or alleged untrue statement) of a material fact contained in any
registration statement, prospectus, offering circular or other document, or any
amendment or supplement thereto, incident to any such registration,
qualification or compliance, or based on any omission (or alleged omission) to
state therein a material fact required to be stated therein or necessary to make
the statements therein, in light of the circumstances in which they were made,
not misleading or any violation of the Purchaser of any rule or regulation
promulgated under the Securities Act applicable to the Purchaser in connection
with any such registration, qualification or compliance, and the Purchaser will
reimburse Seller and each underwriter, if any, for any legal and other expenses
reasonably incurred in connection with investigation, preparing of defending

                                        2

<PAGE>

any such claim, loss, damage, liability or action, provided that the Purchaser
will not be liable in any such case to the extent that any such claim, loss,
damage, liability or expense arises out of or is based on any untrue statement
or omission or alleged untrue statement or omission, made in reliance upon and
in conformity with written furnished to the Purchaser by the Seller or the
underwriter (specifically for inclusion in a registration statement or
prospectus) seeking information.

         (b) Allocation: The parties to this Agreement have agreed that the
Purchase Price shall be allocable as follows:

costs to the Purchaser. Such announcement must be approved by the Seller prior

of the Website.

         (d) Rule 144 Reporting: With a view to making available the benefits of
certain rules and regulations of the SEC which may at any time permit the sale
of the Shares to the public without registration, Purchaser agrees to:

                  (i) make and keep public information available, as those terms
are understood and defined in Rule 144 under the Securities Act, at all times;

                  (ii) file with the SEC in a timely manner all reports and

the Exchange Act, a copy of the most recent annual or quarterly report of the
Purchaser, and such other reports and documents of the Purchaser, and such other
reports and documents so filed as Seller may reasonably request in availing
itself of any rule or regulation of the SEC allowing Seller to sell any such
securities without registration.

Dollars ($1,500,000.00) (the "Minimum Value") at the close of trading on the
date which is one (1) year from the Closing Date of this transaction (the
"Valuation Date"). If the Shares are not worth the Minimum Value at the close of
trading on the Valuation Date, then the Purchaser shall deliver to the Seller
the number of shares of Common Stock in Purchaser so that the Seller receives
the Minimum Value, as determined at the close of trading on the Valuation Date.

3.       NO ASSUMPTION OF OBLIGATIONS BY PURCHASER
         -----------------------------------------

         (a) Except for the Assumed Agreements (as defined herein) Purchaser

correct copies of which have been delivered to Purchaser, to the extent such
obligations are accompanied by a correlated duty of performance or payment on
the part of the other party(s) thereto. Notwithstanding the foregoing, if the

and if no required consent to such assignment and transfer has been obtained
from the third party involved, then such obligation or instrument shall not be
assigned and transferred, but Purchaser shall have the right but not the
